Next Section Next Section Previous Section Previous Section
CCL HISTORICAL INC - S-4 - 20000817 - BUSINESS

POST-MERGER CORECOMM'S INTERNET BUSINESS DEPENDS ON CONTINUED GROWTH OF THE
INTERNET AS A MEDIUM OF COMMUNICATION AND COMMERCE.

Post-merger CoreComm's future success in the Internet service provider business substantially depends on continued growth in the use of the Internet. Although we believe that Internet usage and popularity will continue to grow, it cannot be certain that this growth will continue or that it will continue in its present form. If Internet usage declines or evolves away from post-merger CoreComm's business, its growth in this case will slow or stop and its financial results may suffer.

POST-MERGER CORECOMM'S SERVICES WILL DEPEND UPON ITS NETWORK INFRASTRUCTURE, AND THE FAILURE TO HAVE SUFFICIENT CAPACITY TO ACCOMMODATE NEW USERS, TO MAINTAIN RELIABILITY OR TO MAINTAIN SECURITY COULD HAVE A MATERIAL ADVERSE EFFECT ON POST-MERGER CORECOMM'S ABILITY TO ATTRACT AND RETAIN CUSTOMERS.

Success in post-merger CoreComm's businesses depends, in part, on the capacity, reliability and security of its network infrastructure. Network capacity constraints may occur in the future, both at the local and national levels. These capacity constraints would result in slowdowns, delays or inaccessibility when members try to use a particular service. Poor network performance could cause customers to discontinue service with post-merger CoreComm. Reducing the incidence of these problems will require constantly expanding and improving post-merger CoreComm's infrastructure, which could be very costly and time consuming.

Our Internet services network infrastructure is composed of a complex system of routers, switches, transmission lines and other hardware used to provide Internet access

40

and other services. This network infrastructure will require continual upgrades and adaptation as the number of customers and the amount and type of information they wish to transmit over the Internet increases. This development of network infrastructure will require substantial financial, operational and managerial resources. We cannot be certain that post-merger CoreComm will be able to upgrade or adapt its network infrastructure to meet additional demand or changing customer requirements on a timely basis and at a commercially reasonable cost, or at all. If post-merger CoreComm fails to upgrade its network infrastructure on a timely basis or adapt it to an expanding customer base, changing customer requirements or evolving industry standards, its business could be adversely affected.

Post-merger CoreComm will also have to protect its infrastructure against fire, power loss, telecommunications failure, computer viruses, security breaches and similar events. We do not currently maintain a redundant or backup network operations center. A significant portion of Voyager's computer equipment, including critical equipment dedicated to its Internet access services, is presently located at two network operating centers: one in East Lansing, Michigan and the other in New Berlin, Wisconsin. A natural disaster or other unanticipated occurrence at post-merger CoreComm's switch or collocation facilities, network operations center or points-of-presence through which members connect to the Internet, in the networks of telecommunications carriers post-merger CoreComm will use, or in the Internet backbone in general could cause interruptions in post-merger CoreComm's Internet services.

POST-MERGER CORECOMM'S GROWTH STRATEGY AND ACQUISITIONS MAY NOT BE SUCCESSFUL.

In the future, post-merger CoreComm may acquire or try to acquire products and businesses from, make investments in, or enter into strategic alliances with, companies which have products or distribution networks in its current markets or in areas into which it intends to expand its networks. Any future acquisitions, investments, strategic alliances or related efforts will be accompanied by risks such as:

- the difficulty of identifying appropriate acquisition candidates;

- the difficulty of assimilating the operations of the respective entities;

- the potential disruption of post-merger CoreComm's ongoing business;

- the inability of management to capitalize on the opportunities presented by acquisitions, investments, strategic alliances or related efforts;

- the failure to successfully incorporate licensed or acquired trademarks and technology rights into its manufacturing and distribution of its products;

- the inability to maintain uniform standards, controls, procedures and policies; and

- the impairment of relationships with employees and customers as a result of changes in management.

We cannot assure you that post-merger CoreComm will be successful in overcoming these risks or any other problems encountered with these acquisitions, investments, strategic alliances or related efforts.

41

POST-MERGER CORECOMM WILL DEPEND ON THE SERVICES OF A SMALL NUMBER OF KEY

MANAGEMENT PEOPLE WHO CURRENTLY MANAGE CORECOMM.

We believe that post-merger CoreComm's success depends to a significant extent upon the abilities and continued efforts of CoreComm's current senior management, including George S. Blumenthal, the Chairman of the board of directors, J. Barclay Knapp, its President, Chief Executive Officer and Chief Financial Officer and Patty J. Flynt, its Senior Vice President and Chief Operating Officer. The loss of the services of any of these people could have a negative effect upon post-merger CoreComm's results of operations and financial condition. You should be aware that several members of senior management are officers and/or directors of other companies and that none of these individuals have entered into employment agreements with post-merger CoreComm.

RISK FACTORS RELATING TO POST-MERGER CORECOMM'S CAPITAL STRUCTURE:

POST-MERGER CORECOMM WILL HAVE SUBSTANTIAL INDEBTEDNESS, WHICH COULD ADVERSELY AFFECT ITS FINANCIAL HEALTH AND PREVENT IT FROM FULFILLING ITS OBLIGATIONS UNDER ITS EXISTING DEBT.

Post-merger CoreComm will assume substantial debt and debt service obligations from CoreComm and Voyager. As of June 30, 2000, on a pro forma basis it would have had $351.7 million of consolidated indebtedness outstanding and $661.4 million of stockholders' equity after giving effect to both the ATX merger and the Voyager merger. As of the same date, it would have had $304.3 million of consolidated indebtedness outstanding and $476.6 million of stockholders' equity after giving effect to only the ATX merger, and it would have had $187.4 million of consolidated indebtedness outstanding and $233.2 million of stockholders' equity after giving effect to only the Voyager merger. We also expect post-merger CoreComm to seek significant vendor financing from equipment manufacturers as well as other additional debt financing arrangements.

The substantial amount of debt that post-merger CoreComm will have and that it or its subsidiaries may incur in the future could have important consequences for you. For example, it could:

- limit post-merger CoreComm's ability to obtain additional financing, if needed, for working capital, capital expenditures, acquisitions, debt service requirements or other purposes;

- increase post-merger CoreComm's vulnerability to adverse economic and industry conditions;

- require post-merger CoreComm to dedicate a substantial portion of its cash flow from operations to payments on its debt and accordingly reduce funds available for operations, future business opportunities or other purposes;

- limit post-merger CoreComm's flexibility in planning for, or reacting to, changes in post-merger CoreComm's business and the industry in which it competes; and

- place post-merger CoreComm at a competitive disadvantage compared to its competitors that have less debt.

42

RESTRICTIONS IMPOSED BY POST-MERGER CORECOMM'S DEBT AGREEMENTS MAY SIGNIFICANTLY LIMIT ITS ABILITY TO EXECUTE ITS BUSINESS STRATEGY AND INCREASE THE RISK OF DEFAULT UNDER ITS DEBT OBLIGATIONS.

Any debt instruments for future indebtedness incurred by post-merger CoreComm or its subsidiaries are expected to contain a number of covenants that may significantly limit post-merger CoreComm's or its subsidiaries' ability to, among other things:

- borrow additional money;

- make capital expenditures and other investments;

- pay dividends;

- merge, consolidate or dispose of assets; and

- enter into transactions with related entities.

In addition, in the future, post-merger CoreComm's debt instruments or those of its subsidiaries may contain financial maintenance covenants. If the affected company fails to comply with these covenants, it will be in default under the applicable debt instrument. A default, if not waived, could result in acceleration of indebtedness, in which case the debt would become immediately due and payable. If this occurs, post-merger CoreComm may not be able to repay its debt or borrow sufficient funds to refinance it. Even if new financing is available, it may not be on terms that are acceptable. In addition, complying with these covenants may cause post-merger CoreComm to take actions that it otherwise would not take, or refrain from actions that it otherwise would take.

POST-MERGER CORECOMM WILL HAVE ANTI-TAKEOVER DEFENSE PROVISIONS THAT MAY DETER
POTENTIAL ACQUIRORS AND DEPRESS ITS STOCK PRICE.

Post-merger CoreComm's certificate of incorporation and by-laws will contain provisions that could have the effect of making it more difficult for a third party to acquire, or of discouraging a third party from attempting to acquire, control of post-merger CoreComm. These provisions include the following:

- post-merger CoreComm will be able to issue preferred stock with rights senior to those of its common stock;

- post-merger CoreComm will have a classified board of directors;

- post-merger CoreComm's by-laws will prohibit action by written consent by stockholders; and

- post-merger CoreComm's bylaws will require advance notice for nomination of directors and for stockholder proposals.

The indenture for CoreComm's 6% convertible notes, which will become the obligation of a subsidiary of post-merger CoreComm, also contain provisions that could have the effect of making it more difficult for a third party to acquire, or of discouraging a third party from attempting to acquire, control of post-merger CoreComm. These

43

provisions would require it to make an offer to purchase all of the 6% convertible notes upon a change of control if required by the noteholders. Provisions such as these in post-merger CoreComm's or its subsidiaries' indebtedness may decrease the likelihood that stockholders will receive a possibly substantial premium for their shares over then current market prices, and may limit the ability of stockholders to approve transactions that they may deem to be in their best interest.

In addition, under the shareholder rights plan that may be adopted by post-merger CoreComm, holders of its common stock would be entitled to one preferred share purchase right for each outstanding share of common stock they hold, exercisable under defined circumstances involving a potential change of control as discussed in this joint proxy statement and prospectus. If adopted, the preferred share purchase rights would have the anti-takeover effect of causing substantial dilution to a person or group that attempts to acquire post-merger CoreComm on terms not approved by its board of directors. Those provisions could have a material adverse effect on the premium that potential acquirors might be willing to pay in an acquisition or that investors might be willing to pay in the future for shares of post-merger CoreComm's common stock. Please refer to the section of this joint proxy statement and prospectus entitled "Description of the Capital Stock of Post-merger CoreComm -- The Shareholder Rights Plan."

POST-MERGER CORECOMM MAY HAVE RESTRICTIONS ON DIVIDENDS.

Neither CoreComm nor Voyager has ever paid a cash dividend in respect of its stock, and we do not currently intend to do so in the foreseeable future. In addition, the payment of any dividends by post-merger CoreComm in the future will be at the discretion of its board of directors and will depend upon, among other things, future earnings, operations, capital requirements, its general financial condition, the general financial condition of its subsidiaries and general business conditions.

In addition, post-merger CoreComm's or its subsidiaries' present and future debt instruments may restrict post-merger CoreComm's payment of dividends or the payment of dividends or distributions to post-merger CoreComm by its subsidiaries. Please refer to the section of this discussion of risk factors entitled "Restrictions imposed by post-merger CoreComm's debt agreements may significantly limit its ability to execute its business strategy and increase the risk of default under its debt obligations."

RISK FACTORS RELATING TO THE MERGER TRANSACTIONS:

BECAUSE OF THE CASH COMPONENT OF THE MERGER CONSIDERATION IN BOTH THE ATX MERGER AND THE VOYAGER MERGER, CORECOMM WILL BE REQUIRED TO OBTAIN FINANCING IN ORDER TO COMPLETE THE MERGERS.

The consideration in both the ATX merger and the Voyager merger includes cash, and, therefore, CoreComm intends to undertake either an equity or debt-based financing in order to fund the cash payments prior to closing. On August 14, 2000 CoreComm announced that it had received a total of $310 million of committed financing. This financing is subject to the fulfillment of some conditions, including obtaining an

44

additional $50 million of financing. See "Summary -- Recent Development" for more information regarding the financing commitments and conditions.

Any debt financing that is obtained may have the following effects on post-merger CoreComm:

- post-merger CoreComm will likely have a higher degree of leverage than CoreComm currently does, resulting in a larger amount of debt service costs;

- any debt instruments to which post-merger CoreComm will be subject as a result of financing the mergers will likely have restrictive covenants that may limit post-merger CoreComm's ability to obtain additional financing to fund future working capital, acquisitions or other needs;

- the debt instruments may impose financial and other restrictive covenants that may limit post-merger CoreComm's flexibility in planning for or reacting to changes in its industry; and

- any equity financing may have the effect of diluting the outstanding shares of CoreComm and post-merger CoreComm, and thus may cause a decrease in the share price of CoreComm and post-merger CoreComm common stock.

POST-MERGER CORECOMM MAY NOT BE ABLE TO INTEGRATE VOYAGER OR ATX OR ITS OTHER RECENT ACQUISITIONS. FAILING TO DO SO WOULD ADVERSELY AFFECT ITS RESULTS OF OPERATIONS.

CoreComm entered into the ATX merger agreement and the Voyager merger agreement to strengthen its positions in the provision of both Internet and telephone services and to create the opportunity for potential cost savings. Achieving the benefits of the ATX merger and the Voyager merger will depend in part on integrating technology, operations and personnel in a timely and efficient manner to minimize the risk that the ATX merger and the Voyager merger will result in the unplanned loss of customers or key employees or the continued diversion of the attention of management. Another challenge is to demonstrate to our customers that the ATX merger and the Voyager merger will not result in adverse changes in client service standards or business focus and persuade our personnel that the component companies' business cultures are compatible. We cannot assure you that the ATX merger and the Voyager merger can be successfully integrated or that any of the anticipated benefits will be realized, and failure to do so could have a material adverse effect on post-merger CoreComm's business, financial condition and operating results.

Moreover, Voyager has expanded its operations rapidly during the past two years. Much of this growth is attributable to 27 acquisitions that Voyager has made since July 1998. Furthermore, during 1999, CoreComm acquired MegsINet Inc. and USN Communications Inc. and is continuing to integrate those acquisitions. Failure to integrate these acquisitions successfully could have a material adverse effect on post-merger CoreComm's business, financial condition and operating results.

45

GENERAL RISK FACTORS:

MANY OF POST-MERGER CORECOMM'S OFFICERS AND DIRECTORS FACE POTENTIAL CONFLICTS OF INTEREST BECAUSE THEY ARE OFFICERS AND DIRECTORS OF OTHER COMPANIES IN THE TELECOMMUNICATIONS INDUSTRY, WHICH COULD IMPEDE THEIR ABILITY TO MAKE DECISIONS FOR POST-MERGER CORECOMM. IN ADDITION, SOME OF POST-MERGER CORECOMM'S OFFICERS AND OTHER EMPLOYEES ARE EMPLOYED BY POST-MERGER CORECOMM'S AFFILIATES.

Many of post-merger CoreComm's directors and officers are also directors and officers of other companies in post-merger CoreComm's industry, and some are employed by historical affiliates of post-merger CoreComm. In addition, some of post-merger CoreComm's officers and all of its directors are also officers and/or directors of NTL Incorporated, a commonly managed historical affiliate, which is a telecommunications company that has historical ties to CoreComm. From time to time, opportunities may arise that would be pursued by one or more of these companies and post-merger CoreComm at the same time. In addition, CoreComm and NTL have entered into various transactions and service arrangements. Because all of post-merger CoreComm's directors will be directors of NTL, decisions about these opportunities or transactions may result in conflicts of interest. In those instances, post-merger CoreComm's board of directors will seek to act, with the advice of its counsel, in a manner consistent with each director's duties to post-merger CoreComm and its stockholders under applicable law.

Furthermore, many of post-merger CoreComm's officers and employees will allocate their business time between post-merger CoreComm and NTL. These officers and employees will not be available on a full-time basis to post-merger CoreComm in the future, and they may have duties to these other companies which may interfere with their duties to post-merger CoreComm.

RISK FACTORS RELATED TO VOYAGER THAT WILL BE APPLICABLE TO POST-MERGER CORECOMM PRIMARILY BECAUSE OF THE COMPLETION OF THE VOYAGER MERGER:

VOYAGER'S OPERATING RESULTS FLUCTUATE.

Voyager has experienced significant fluctuations in its results of operations on a quarterly and annual basis, which it expects to continue to experience in its future quarterly and annual results of operations due to a variety of factors, many of which are outside of Voyager's control, including:

- demand for and market acceptance of Voyager's services;

- customer retention;

- the timing and magnitude of capital expenditures, including costs relating to the expansion of operations and network infrastructure;

- introductions of new services or enhancements by Voyager and its competitors;

- increased competition in Voyager's markets within the Midwest;

- growth of Internet use and establishment of Internet operations by mainstream enterprises;

46

- changes in Voyager's and its competitors' pricing policies; and

- general economic conditions affecting Voyager's industry.

VOYAGER'S FUTURE SUCCESS DEPENDS SIGNIFICANTLY ON RETAINING EXISTING CUSTOMERS
AND GENERATING NEW ONES.

Voyager believes that its long-term success depends largely on its ability to retain existing customers while continuing to attract new customers. Voyager has invested significant resources in its network infrastructure and customer and technical support capabilities to provide high levels of customer care. Voyager cannot be certain that these investments will maintain or improve its customer retention rate. Voyager believes that intense competition from its competitors, some of which offer free hours of service or other enticements for new customers, has caused, and may continue to cause, some of Voyager's customers to switch to its competitors' services. Voyager is also susceptible to losing customers that it acquires through its acquisitions due to the customers' lack of familiarity with Voyager and the billing and network difficulties that sometimes occur after an acquisition. In addition, some new subscribers use the Internet only as a novelty and do not become consistent users of Internet services and, therefore, may be more likely to discontinue their service. These factors may adversely affect Voyager's subscriber retention rates, which would have an adverse effect on its business and operating results.

RISK FACTORS RELATING TO THE TERMS OF THE VOYAGER MERGER AGREEMENT:

VOYAGER STOCKHOLDERS CANNOT BE CERTAIN OF THE MARKET VALUE OR THE AVERAGE TRADING PRICE OF THE POST-MERGER CORECOMM COMMON SHARES THEY WILL RECEIVE FOR THEIR SHARES OF VOYAGER COMMON STOCK

In the Voyager merger, Voyager stockholders will be entitled to receive 0.292 of a post-merger CoreComm common share plus $3.00 in cash for each share of Voyager common stock they hold.

If the average per share trading price of CoreComm common shares is less than $33.03, Voyager has the right to terminate the Voyager merger agreement, subject to CoreComm's ability to prevent Voyager from doing so. In order for CoreComm to prevent termination, it would have to increase the fraction of a post-merger CoreComm common share to be issued to Voyager stockholders for each Voyager share such that the value of the CoreComm common shares to be included in the consideration paid for each share of Voyager common stock will not be lower than $12.02. If CoreComm elects not to exercise this "topping-up" right, the Voyager merger agreement would then be terminated. However, Voyager may elect not to exercise its right to terminate the Voyager merger agreement. In that case, the aggregate value to be received for each share of Voyager common stock, based on the average trading price, would be less than $15.02.

If the average per share trading price of CoreComm common shares is less than $41.17 and at or above $33.03, then the fraction of a post-merger CoreComm share to be issued to Voyager stockholders for each Voyager share will be increased such that

47

total merger consideration (including the $3.00 in cash) for each share of Voyager common stock will not be lower than $15.02. As a result, post-merger CoreComm could be required to issue more than 0.292 of a post-merger CoreComm common share in exchange for each share of Voyager common stock.

If the average per share trading price of CoreComm common shares during a specified period shortly before the completion of the Voyager merger is at or below $56.97 and at or above $41.17, for each share of Voyager common stock, Voyager stockholders will receive 0.292 of a share of post-merger CoreComm stock plus $3.00 in cash. Because the average trading price of shares of CoreComm stock may fluctuate while the exchange ratio is fixed, Voyager stockholders would receive between $15.02 and $19.64 in total merger consideration (including the $3.00 in cash). Therefore, a decrease in the average trading price of CoreComm common shares within the range will result in Voyager stockholders receiving a set number of post-merger CoreComm common shares at a lower value and thus less total merger consideration.

If the average per share trading price of CoreComm common shares is greater than $56.97, the fraction of a post-merger CoreComm common share to be issued to Voyager stockholders for each Voyager share will be reduced such that total merger consideration (including the $3.00 in cash) for each share of Voyager common stock will not exceed $19.64. As a result, Voyager stockholders may receive less than 0.292 of a post-merger CoreComm common share in exchange for each share of Voyager common stock.

If the Voyager merger has not occurred by July 15, 2000 due to reasons specified in the Voyager merger agreement, the fraction of a post-merger CoreComm common share to be issued to Voyager stockholders for each Voyager share will be fixed at 0.292 if the average per share trading price of CoreComm common shares is at or above $41.17 and no greater than $58.17 (not $56.97). The upper threshold will increase at a fixed rate for each 31-day period elapsed after July 31, 2000 in which the Voyager merger is not completed. If these specified events occur, the value of the consideration (including the $3.00 in cash) Voyager stockholders will receive for each share of Voyager common stock may exceed $19.64.

The average per share trading price of CoreComm common shares is computed based on the volume weighted-average trading price of CoreComm common shares on the Nasdaq Stock Market for ten randomly selected trading days out of the 20 consecutive trading days ending on the last trading day prior to closing of the Voyager merger. However, the actual trading price of CoreComm common shares at the time of the closing of the Voyager merger may be either higher or lower than the average trading price, so the actual market value of the post-merger CoreComm common shares you receive in the Voyager merger may be either higher or lower than the value of those shares for purposes of calculating the amount of consideration under the Voyager merger agreement. The average trading price of CoreComm common stock may vary because of factors such as:

- changes in the business, operating results or prospects of CoreComm, ATX or Voyager;

48

- market assessments of the likelihood that the Voyager merger or ATX merger will occur;

- the timing of the completion of the Voyager and/or ATX merger;

- the prospects of operations post-Voyager merger and post-ATX merger;

- adjustments resulting from stock splits, spin-offs or similar events; and

- the general market and economic conditions.

In addition, the exchange of the certificates representing shares of Voyager common stock for certificates representing shares of post-merger CoreComm common stock will not take place immediately upon completion of the Voyager merger. Voyager stockholders will thus be unable to sell or otherwise transfer these shares of post-merger CoreComm common stock for a period following the completion of the Voyager merger. The market value of the shares of post-merger CoreComm common stock may be either lower or higher at the time Voyager stockholders receive certificates representing shares of post-merger CoreComm common stock and thus become able to sell those shares, than at the time of the Voyager merger.

THE TERMINATION FEE AND VOTING AGREEMENT MAY DISCOURAGE OTHER COMPANIES FROM
TRYING TO ACQUIRE VOYAGER.

In the Voyager merger agreement, Voyager agreed to pay a termination fee of $19.0 million to CoreComm in specified circumstances, including some circumstances where a third party acquires or seeks to acquire Voyager. This provision could discourage other companies from trying to acquire Voyager, even if those other companies might be willing to offer a greater amount of consideration to Voyager stockholders than CoreComm has offered in the Voyager merger agreement. Payment of the termination fee would have a material adverse effect on Voyager's financial condition. In addition, in connection with the execution of the Voyager merger agreement some of the directors and officers of Voyager, holding 63.9% of the outstanding shares of Voyager common stock, entered into a voting agreement with CoreComm. These stockholders agreed to vote their shares in favor of the Voyager merger agreement and granted CoreComm and its designees irrevocable proxies to vote their shares in favor of the Voyager merger. In some circumstances, this agreement will remain in effect for a period of six months after the Voyager merger agreement is terminated. These provisions may discourage other companies from trying to acquire Voyager.

RISK FACTORS RELATED TO ATX THAT WILL BE APPLICABLE TO POST-MERGER CORECOMM PRIMARILY BECAUSE OF THE COMPLETION OF THE ATX MERGER:

RISK FACTORS RELATING TO THE BUSINESS OF ATX:

ATX MAY BE REQUIRED TO MAKE SIGNIFICANT CAPITAL EXPENDITURES RELATING TO ITS
INFORMATION SYSTEMS INFRASTRUCTURE.

ATX's billing, customer service and management information systems are vital to its growth and its ability to bill customers, monitor costs and respond to customer service issues. As ATX continues its transition to being a full service, integrated telecommunica-

49

tions provider, its need for sophisticated systems will increase. The cost of implementing these systems has been, and will continue to be, significant. Additionally, any of the following developments could negatively affect ATX's business or financial condition:

- ATX's failure to adequately and timely identify all of its information and processing needs;

- the failure of ATX's systems to operate as expected;

- ATX's failure to upgrade systems as necessary; and

- failure by third party service providers to deliver necessary systems or services.

ATX IS A PRIVATE COMPANY AND RELIES TO A SIGNIFICANT EXTENT ON SERVICES AND OTHER ASSISTANCE PROVIDED AT MARKET COST BY AFFILIATES AND OWNERS OF ATX. THIS ASSISTANCE WILL NO LONGER BE AVAILABLE TO ATX AFTER THE ATX MERGER.

For fifteen years, ATX has operated as a private company. Only recently has ATX begun to implement initiatives to create and expand its management infrastructure so that ATX's growth can be sustained. For instance, ATX currently shares employees with University City Housing, an entity controlled by Michael Karp, the Chief Executive Officer and the majority stockholder of ATX. University City Housing provides general accounting, cash management, tax return preparation, payroll and human resources services to ATX. Under a transition services agreement, these arrangements will be provided on a scale that will be reduced over time following the completion of the ATX merger. Failure to replace the services and assistance formerly provided by affiliates and owners of ATX on terms acceptable to ATX could result in material disruptions to the business and operations of ATX.

RISK FACTORS RELATING TO THE TERMS OF THE ATX MERGER AGREEMENT:

THE MARKET PRICE OF POST-MERGER CORECOMM COMMON STOCK AFTER THE ATX MERGER IS
UNCERTAIN BECAUSE OF THE COMPLEX STRUCTURE OF THE ATX MERGER.

There is currently no public market for ATX common stock. While it is believed that the securities markets will recognize that, despite its complex structure, the ATX merger is actually an acquisition of ATX by CoreComm, and treat post-merger CoreComm's common stock as it has CoreComm common shares historically, there can be no assurance that an active trading market will develop or be sustained. There is uncertainty as to the prices at which the shares of post-merger CoreComm common stock will trade.

VOYAGER.NET, INC.

Voyager is a large Internet communications company focused in the Midwestern United States with approximately 368,000 subscribers as of June 30, 2000. Voyager provides high-speed data communications services and Internet access to residential and business subscribers. Services include high-speed DSL, providing dedicated telecommunications services to business, cable modem access, dial-up Internet access, Web-hosting, electronic commerce, situating servers at a common location and long distance phone services. Voyager operates the largest dial-up Internet network in the Midwest in terms of geographic coverage, with approximately 200 Voyager-owned points of presence in Michigan, Wisconsin, Ohio, Illinois, Indiana and Minnesota. Voyager has competitive local exchange carrier status in Michigan, Ohio, Indiana and Wisconsin.

INDUSTRY BACKGROUND

The Internet has rapidly developed into an integral business and personal communications tool. Consumers and businesses are demanding solutions that provide them with the ability to access and utilize the Internet in a fast, secure and reliable manner. Factors driving the growth in the number of Internet users and Web sites include the large and growing installed base of low-cost personal computers, advances in the performance and speed of personal computers and modems, improvements in network infrastructure, easier access to the Internet and the increasing importance of the Internet as a communications and commercial medium. Businesses have also rapidly established corporate Internet sites and connectivity as a means to expand customer reach and improve communications efficiency. Many businesses are utilizing the Internet as a lower cost alternative to certain traditional telecommunications services.

The Internet communications market is highly fragmented. These Internet service providers vary widely in their geographic coverage, customer focus and the nature and the quality of their services. The Internet service provider market is generally segmented into three broad categories:

- national providers that are typically full-service providers that offer a broad range of Internet access and other services to businesses;

- regional providers that include the regional telephone operators, competitive local exchange carriers and Internet access providers, such as Voyager; and

52

- local providers that are typically closely-held start-ups or small companies serving a single market.

The vast majority of Internet communication companies are small, local operations with fewer than 10,000 customers each.

Despite the growth in the Internet communications industry, very few Internet communication companies are profitable. In addition, the dramatic growth of Internet usage and dependency has prompted customers to demand from their providers more enhanced technology and services and reliable, high-speed, quality Internet access. Thus, Internet service providers will be faced with expending significant capital resources to attract and retain subscribers. As a result, the industry is expected to undergo substantial consolidation over the next few years, particularly among the local providers, who typically lack the financial resources necessary to continue to compete. Voyager believes that the anticipated growth in Internet use and the significant number of under- capitalized local providers within its region meeting its acquisition criteria provides Voyager with an excellent opportunity to extend its scalable business model.

VOYAGER

The business model that Voyager has developed has resulted in substantial revenue and subscriber growth, reduced customer acquisition costs and significant cash flow from operations and includes customer satisfaction efforts. Voyager's business model is based on the following key principles:

- Voyager controls the costs of acquiring new customers by focusing on markets in the Midwestern United States, thereby reducing the need for more expensive, broad-based marketing campaigns;

- Voyager focuses on delivering product quality and services and customer care, which Voyager believes results in word-of-mouth referrals and customer retention greater than the industry average;

- Voyager manages 100% of its network equipment and customer care operations, which reduces its telecommunication costs and enhances control over its network utilization, efficiency, scalability and quality, and Voyager owns or leases 100% of its network equipment; and

- Voyager realizes cost savings and economies of scale from its acquired businesses by reducing duplicated network infrastructure and taking steps to consolidate sales and marketing, network operations, customer support and back office operations.

Voyager has begun to implement a strategy to become a leading provider of high-speed DSL services in the Midwest. DSL technology is a high-speed Internet connectivity option using existing telephone wiring, widely heralded as the next-generation Internet connectivity option. DSL enables connection speeds up to 50 times faster than using a standard, 28.8 Kbps modem over existing phone lines. Voyager's DSL deployment strategy will establish a network capable of providing bundled phone, high-speed Internet and future communications services.

53

DSL technology is particularly well suited for small and medium-sized businesses looking to connect their entire staff to the Internet over a single high-speed Internet connection, or for customers looking to access the Internet at top speeds. DSL includes the following benefits:

- provides a dedicated, "always on" connection;

- is faster than integrated services digital network and modem connections;

- is more affordable than dedicated T1 and frame relay connections; and

- is more reliable, and less complicated to use than dial-up connectivity options.

Voyager has a two-tiered strategy to provide DSL services:

- provide DSL services directly as a competitive local exchange carrier to customers in secondary and tertiary markets throughout our region; and

- continue to provide DSL services through existing relationships with major data competitive local exchange carriers in selected major metropolitan areas.

Voyager expects to soon begin deploying DSL services in approximately 40 cities from the central offices of 240 incumbent local exchange carriers, reaching more than 400,000 small and medium-sized business customers and 3.8 million residential customers. Voyager is targeting secondary and tertiary markets within its region, covering areas that are less competitive than the major metropolitan areas. Target markets include Michigan cities of Alpena, Ann Arbor, Battle Creek, Charlotte, Flint, Gaylord, Grand Rapids, Hastings, Hillsdale, Jackson, Kalamazoo, Lansing, Petoskey, Sturgis, Three Rivers, and Traverse City; Ohio cities of Akron, Canton, Dayton, Hamilton, Middletown, Springfield, Toledo, Troy, and Youngstown; Indiana cities of Columbus, and Seymour; Illinois cities of Aurora, Elgin, and Joliet; and Wisconsin cities of Appleton, Kenosha, Madison, Milwaukee, Newberg, Stevens Point, Green Bay, and Vandyne. When Voyager's DSL network is deployed in these cities, service will be available in more than 170 cities and townships in the Midwest region.

Voyager is well positioned to begin offering DSL services directly to its customers in its Midwest region as it has a strong presence, a large installed customer base, and a substantial network infrastructure. Voyager's high-speed strategy is intended to establish Voyager as one of the dominant providers of DSL services in the Midwest. Voyager's sales and marketing plans include up-selling its installed customer base as well as attracting customers from other providers in the region.

Web Services. Voyager's Web services help organizations and individuals implement their Web site and e-commerce goals. Voyager offers various Web hosting and other services that enable customers to establish a Web site presence without maintaining their own Web servers and high-speed connectivity to the Internet.

- WEB HOSTING. Voyager offers a diverse range of shared, dedicated and co-location Web hosting services for small and medium businesses. Voyager's Web hosting service includes state-of-the-art Web servers, high-speed connections to the Internet at its network operations centers, and registration of Voyager's customers' domain name and Internet address. Voyager also offers Web page design, development, maintenance and traffic reporting and consulting services. Voyager currently has over 12,900 Web hosting subscribers.

- CO-LOCATION. Voyager offers co-location services, providing telecommunications facilities for customer-owned Web servers, for customers who prefer to own and have physical access to their servers but require the reliability, security and performance of its on-site facilities. Voyager's co-location customers house their equipment at Voyager's secure network operating centers and receive direct high-speed connections to the Internet.

Content is made available through revenue sharing and co-branding agreements with organizations including CMGI Inc.'s MyWay.com, Wizshop.com, Amazon.com, eToys, and local media. Customers access the portal page at www.voyager.net.

Other Services and Offerings. Voyager also offers other enhanced communications services to meet the one-stop shopping demands of residential and business customers.

- VIRTUAL PRIVATE NETWORKS. Voyager's custom virtual private networks solutions enable its customers to deploy tailored, Internet protocol-based mission-critical business applications for internal enterprise, business-to-business and business-to-

56

customer data communications on its network while also affording high-speed access to the Internet. Voyager offers its customers a secure network on which to communicate and access information between an organization's geographically dispersed locations, collaborate with external groups or individuals, including customers, suppliers, and other business partners and use the Web to access information on the Internet and communicate with other Web users.

- LONG DISTANCE AND OTHER TELECOMMUNICATIONS. Voyager currently resells long distance telecommunications services as well as an 800 service, calling cards and prepaid cards to its Internet customers through its VoyagerLink operations. Voyager currently offers this interstate and intrastate long-distance service to its customers at a fixed rate per minute, with no set-up or monthly charges. Voyager also has begun offering bundled voice and data services to customers who seek Internet access and telecommunications services from a single source.

SALES AND MARKETING

Marketing. Voyager's marketing philosophy is based on the belief that a consumer's selection of an Internet service provider is often strongly influenced by a personal referral. Accordingly, Voyager believes that the customer satisfaction of its subscriber base has led to significant word-of-mouth referrals. Voyager's referral incentive program awards subscribers one month of free service for every customer referred. As a result, over 70% of new sign-ups come from existing subscriber referrals. Voyager's proprietary customer care and billing system automatically tracks and credits the subscriber's account, thus providing Voyager with valuable marketing information and flexibility with this program. Voyager also markets its services through strategic relationships with value added resellers in the local communities, such as computer stores, trade associations, unions, Web development companies, local area network administrators and other retail stores which represent and promote Voyager on a commission basis. These relationships are a significant source of new customers. In addition, Voyager offers free Internet training classes within its markets to cultivate interest in the Internet and increase brand recognition. Voyager does not use mass marketing media as a major source of acquiring new customers, but instead believes that by providing superior customer service and developing strong relationships within local communities, particularly in small- and medium-sized markets, Voyager can continue to grow at rates greater than the industry average with very low costs per new customer acquired.

Web-based Marketing. Voyager maintains a Web site (www.voyager.net) that provides Internet users with the opportunity to learn about Voyager and enroll in one of its Internet access service plans. Upon viewing information on Voyager's services, potential customers can either subscribe online or contact a customer support employee for enrollment. Customers who sign up online or through Voyager's toll-free number have their accounts created immediately and are thus able to use their accounts within minutes of account activation.

57

Free CDs and Diskettes. Upon the request of prospective customers, Voyager distributes free software via CD and diskettes that contain both the Netscape browser software for Windows 95, Windows 3.1 and Macintosh as well as Microsoft's Internet Explorer 4.0. The software is configured to facilitate installation and connection to a Voyager point of presence. Individuals receiving the CD or diskettes have the opportunity to obtain the free browser software contained on the CD by opening an account with Voyager, either online or via a toll-free telephone number. New customers can be online in a matter of minutes after opening an account online or by calling Voyager's toll-free telephone number.

Business Sales and Support. Voyager has a business sales and support team dedicated to selling and providing customized support to its growing small- and medium-sized business customers. Voyager's business teams include support personnel located throughout its target region. This strong local presence allows it to meet face-to-face with its business customers to evaluate their needs and respond with customized solutions. Voyager's locally-based sales and support teams are supported by additional network engineers at its headquarters for trouble-shooting on specific problems.

CUSTOMER SERVICE AND TECHNICAL SUPPORT

Voyager provides its customer service and technical support through two large call centers located in East Lansing, Michigan and New Berlin, Wisconsin. Voyager provides 100% of its customer care internally and does not outsource any customer operations to third party providers. Voyager has staffed its call centers with over 260 employees, or more than 50% of its workforce. Voyager's two main centers are fully-integrated so that both centers can handle calls from subscribers located anywhere within the region. This interoperability allows Voyager to more efficiently handle support calls, thus reducing telephone hold times. Voyager has upgraded its phone system that routes calls, tracks important call-in data, automatically answers certain questions and moves customers quickly through the call-in process. Its comprehensive staff training program and incentive compensation program linked to customer satisfaction has led to significant improvements in the time required to move subscribers through the various calling queues. In addition to using Voyager's call centers, subscribers can also e-mail questions directly to technical support staff, as well as find solutions online through the use of the tutorials found at Voyager's Web site. Voyager's free Internet training and educational classes within its markets also allow its customers and potential subscribers to ask questions about the Internet and Voyager's services.

NETWORK AND TECHNOLOGY

Network Infrastructure. Voyager designed and built its network to specifically service Internet (data) traffic. The network is comprised primarily of the latest Cisco Systems' routing and switching equipment, which provides a common platform for increased flexibility and maintenance while allowing for the use of advanced routing protocols to quickly and dependably deliver customer traffic. Voyager has two network operating centers to oversee traffic flows and general network operations, as opposed to a single network operating center as found in many national networks, which helps create

58

redundancy and ensures a secure and reliable network. Voyager is continuously improving its network infrastructure and connectivity costs through its relationships with incumbent local exchange carriers such as Ameritech Corporation and GTE Corporation as well as with competitive local exchange carriers such as Brooks Fiber (MCI WorldCom), Phone Michigan (McLeodUSA), Time Warner, Coast to Coast and Focal Communications.

Voyager's points of presence are linked to regional network points, or hubs, which are its two network operating centers. These network points are linked to the Internet by fiber optic connections and employ asynchronous transfer mode, frame relay and other methods of handling traffic efficiently. Interlinked network points allow Internet users to access sites located on other network points. In the event that one of its subscribers wishes to access a Web site that is located on another service provider's network, data is directed to a network access point where information sharing is conducted under arrangements known as peering. The flow of information across a network access point allows information to be downloaded from one service provider's network to a subscriber on another service provider's network.

Points of Presence. Voyager's approximately 200 dial-in points of presence primarily utilize digital access servers manufactured by 3Com Corporation and Lucent Technologies, Inc. These servers allow for a variety of customer connections from standard dial-up to traditional telecommunications lines, including integrated digital services network. Voyager's network has been reconfigured to include redundant data circuits which will automatically route customer traffic in the event of a failure. Voyager's network topology offers high levels of performance and security. Through various relationships with competitive local exchange carriers, Voyager has been able to reduce the overall number of points of presence by consolidating several of them into "SuperPOPs" with expanded calling areas. The SuperPOP allows Voyager to consolidate its equipment into one large modem bank and eliminate various telecommunication links from its points of presence back to the network operating center, thereby creating enhanced network reliability and reducing telecommunication costs. Voyager has worked with its providers to create additional SuperPOPs and Voyager intends to explore opportunities to create additional SuperPOPs in the future.

Network Operation Centers. Voyager has two main network operation centers, or hubs, in East Lansing, Michigan and New Berlin, Wisconsin. These two hubs house all of its internal network equipment, including servers, routers, mail, hosting and disk arrays, as well as its main routing equipment and connection to the Internet. The two hubs have been interconnected to provide redundancy and to ensure the highest quality network. The hubs are monitored on a 24 hours per day, seven days per week basis in order to provide the highest level of network performance.

Peering Relationships. Peering is the act of exchanging data across networks, typically at specific, discrete locations. By allowing separate networks to exchange data, users on a particular Internet service provider's network are able to access information and communicate with users on another provider's network. Many formal peering points exist where several dozen Internet service providers and other providers exchange data,

59

including network access points. Internet service providers can also run connections to peer with several different providers, known as multihoming. Multihoming allows an Internet service provider to provide better service, as inbound and outbound data can go over different routes if a particular network is overloaded. Voyager has relationships at multiple points with several different organizations, including Verio, Inc. in Ann Arbor, Michigan, NAP.net in Chicago, Illinois and MCI and Savvis in Kalamazoo, Michigan, thus building in network redundancy that allows for better connectivity for its customers.

Integrating Acquired Networks. As Voyager continues to play a leading role in consolidating the Internet service provider industry, one of its tasks is to configure the acquired equipment and network into its regional Internet-based network. Voyager has taken steps to gain scale economies by eliminating redundant and expensive Internet connectivity and better utilizing Voyager's current infrastructure. Its integration plan calls for connecting the acquired points of presence directly to its network at the most cost effective point and eliminating duplicate Internet telecommunication costs. Voyager typically connects within three to six months after the acquisition so as to allow for a prompt yet smooth integration of the acquired networks and to reduce service disruptions.

COMPETITION

The Internet services market is extremely competitive and highly fragmented. Voyager faces competition from numerous types of providers in its six state region and anticipates that competition will only intensify in the future as the Internet service provider industry consolidates. Voyager believes that the primary competitive factors determining success as an Internet service provider are:

- accessibility and performance of service;

- quality customer support;

- price;

- access speed;

- brand awareness;

- ease of use; and

- scope of geographic coverage.

Voyager believes that it has competed favorably based on these factors, particularly due to:

- regionally focused operating strategy;

- focus on customer care and service;

- performance of Voyager-owned network facilities; and

- competitive, multi-tiered pricing policy.

60

Voyager's current competitors include many large companies that have substantially greater market presence, brand name recognition and financial resources. Some of Voyager's local or regional competitors may also enjoy greater recognition within a particular community. Voyager currently competes, or expects to compete, with the following types of companies:

- established online information service providers, which provide basic Internet access as well as proprietary information not available through public Internet access, such as America Online, Inc.;

- national Internet service providers, including EarthLink Network, Inc.;

- numerous regional and local Internet service providers, some of which have significant market share in their particular market area;

- providers of Web hosting, co-location and other Internet-based business services, such as Verio, Inc.;

- computer hardware and software and other technology companies that provide Internet connectivity with their products, including IBM and Microsoft Corporation;

- national long distance carriers such as AT&T Corporation, MCI WorldCom and Sprint Corporation;

- regional Bell operating companies and local telephone companies;

- cable operators, including Tele-Communications, Inc. and Time Warner Cable; and

- nonprofit or educational Internet service providers.

Many of the major cable companies and some other Internet access providers have begun to offer or are exploring the possibility of offering Internet connectivity through the use of cable modems. Cable companies, however, are faced with large-scale upgrades of their existing plant equipment and infrastructure in order to support connections to the Internet backbone via high-speed cable access devices. Voyager believes that there is a trend toward horizontal integration through acquisitions or joint ventures between cable companies and telecommunications carriers. Other alternative service companies have also announced plans to enter the Internet connectivity market with various wireless terrestrial and satellite-based service technologies. In addition, several competitive local exchange carriers and other Internet access providers have launched national or regional digital subscriber line programs providing high speed Internet access using the existing copper telephone infrastructure. Several of these competitive local exchange carriers have announced strategic alliances with local, regional and national Internet service providers to provide broadband Internet access. Recently, several national access providers have begun to offer Internet access for free or at substantial discounts to prevailing rates, which may result in significant pricing pressure. Voyager also believes that manufacturers of computer hardware and software products, media and telecommunications companies and others will continue to enter the Internet services market, which will also intensify competition. Any of these developments could materially and adversely affect Voyager's business, operating results and financial condition.

61

GOVERNMENT REGULATION

The further deployment of competitive services in the market will continue to be hampered by incumbent local exchange carrier activities. This is a challenge not only affecting Voyager, but affects all competitive local exchange carriers in all states in the country.

Voyager has begun negotiations of interconnection agreements with the major incumbent local exchange carriers in its service territories. These agreements set forth the terms, conditions and rates of Voyager's interconnection with the incumbent local exchange carriers' telecommunications networks, including, but not limited to, co-location and UNEs. Under the Federal Telecommunications Act of 1996, these negotiations are to be commenced upon the competitive local exchange carriers' written request for negotiations. If an interconnection agreement is unable to be negotiated within 135-160 days after the incumbent local exchange carriers' receipt of the written request for negotiation, either party may petition the state public service commission/ public utility commission for arbitration of the outstanding issues. Although each state varies as to its own arbitration practice and procedure, parties generally present oral and written evidence, participate at hearings at which witnesses are subject to cross examination, and are allowed to submit briefs and response briefs in support of their respective positions. 180-210 days after the complaint for arbitration is filed is the normal time frame within which the state commission will issue their decision.

Even if Voyager does not have an interconnection agreement with a particular incumbent local exchange carrier, Voyager is able to order service from the incumbent local exchange carrier's tariff in most circumstances. This allows Voyager to continue to move forward with implementing its business plan even though Voyager may not have an executed interconnection agreement. Upon execution of an interconnection agreement, Voyager's continued ordering of service from the incumbent local exchange carrier will be under the interconnection agreement in what should be a seamless transition.

In addition to Voyager's competitive local exchange carrier services, Voyager provides long distance service as a reseller through its subsidiary Horizon Telecommunications, Inc. Long distance service consists of both intrastate and interstate service and therefore is influenced by decisions of both state commissions and the FCC. Voyager is authorized in all six states in which it provides long distance service: Indiana, Illinois, Michigan, Minnesota, Ohio and Wisconsin. As a reseller, Voyager does not have the significant capital investment in network equipment necessary to provide long distance telephone service. The state commissions and the FCC have implemented rules and procedures for the transferring of customers from one provider to another in order to reduce "slamming," the transfer of the customer from one long distance carrier to another without the customer's consent. Voyager has long implemented procedures to obtain a letter of authority, or other approved method (e.g., third party verification), to confirm that the customer does in fact want to change from its current long distance provider to Voyager. Voyager has tariffs on file with the FCC setting forth the terms, conditions and rates applicable to its provisioning of long distance service. Although the long distance regulatory environment is not as active as the local telecommunications arena, it is difficult to predict how either state and/or federal regulatory authority will

62

impact the provisioning of long distance service in the short or long term. For more information on government regulation of the telecommunications industry, please refer to the section of this joint proxy statement and prospectus entitled "Government Regulation of the Telecommunications Services Business."

INTELLECTUAL PROPERTY

Voyager has developed and acquired certain proprietary rights for which it has sought and will continue to seek federal, state and local protection. Voyager relies on a combination of copyright, trademark and trade secret laws to protect its proprietary rights, particularly related to its names and logos. "Voyager.net" and the associated logo are names and marks which belong to Voyager. In addition, Voyager has registered VoyagerLink and several other names, marks and logos, and has additional registrations pending for names and marks, under which it does business at local levels within its region. An integral part of its successful business strategy is its proprietary Web-based customer care and billing system. Voyager is exploring whether to seek patent protection with respect to this customer care system and will act accordingly. Voyager has each of its employees enter into an inventions agreement under which each agrees that any intellectual property rights developed while in Voyager's employment belong to Voyager. Voyager cannot assure you that the steps taken by it to protect its proprietary rights will be adequate to prevent misappropriation of its technology or that third parties, including competitors, will not independently develop technologies that are substantially equivalent or superior to its proprietary technology.

In connection with the delivery of its access and other services, Voyager relies on the use of products of software manufacturers that it bundles in its software for users with personal computers operating on the Windows or Macintosh platforms. While some of the applications included in its start-up kit for access service subscribers are shareware that it has obtained permission to distribute or that are otherwise in the public domain and freely distributable, certain other applications included in the start-up kit have been licensed where necessary. Voyager currently intends to maintain or negotiate renewals of all existing software licenses and authorizations as necessary, although Voyager cannot be certain that such renewals will be available to it on acceptable terms, if at all. Voyager may also enter into licensing arrangements in the future for other applications.

EMPLOYEES

As of June 30, 2000, Voyager had 487 employees, including 408 full-time employees and 79 regular part-time employees. Voyager is not a party to any collective bargaining agreements covering any of its employees, has never experienced any material labor disruption and is unaware of any current efforts or plans to organize its employees. Voyager considers its relationships with its employees to be good.

PROPERTIES

Voyager leases each of its office locations. Voyager leases currently cover in the aggregate approximately 55,000 square feet of space. Voyager has two primary lease locations which serve as its network operating centers: East Lansing, Michigan, which is also its corporate headquarters, with approximately 17,000 square feet, which lease

63

expires in 2007; and New Berlin, Wisconsin, where Voyager leases space at four locations covering in the aggregate approximately 25,000 square feet under long-term leases. Voyager recently renegotiated its leases in East Lansing and New Berlin to increase the square feet of space at these facilities to approximately 32,000 square feet and 67,000 square feet, respectively. The effective time of each lease is expected to be mid-July. Voyager also leases space, typically less than 50 square feet per location, to house its network equipment at each of its points of presence. Voyager does not own any real estate. Voyager believes that its current facilities are suitable and adequate for its business and, upon expiration of its leases, Voyager does not anticipate any significant difficulty in obtaining renewals or alternative space in its desired markets.

LITIGATION

Voyager has been, from time to time, involved in various litigation matters arising in the ordinary course of business. Voyager is not involved currently in any pending legal proceedings that, either individually or taken as a whole, will have a material adverse effect on its business, financial condition and results of operations.

ATX TELECOMMUNICATIONS SERVICES, INC.

ATX offers its customers a full range of high-speed communications services including long distance, local, wireless and network services such as network data integration, Internet access and Web consulting, development and hosting throughout the New York-Virginia corridor. In addition, ATX offers Advanced Communications Solutions products tailored to meet the needs of its business customers, such as conference calling, travel services, pre-paid calling, enhanced fax and PC-based billing. Customers are billed on a single, consolidated invoice, delivered by traditional means or near real time Web-based billing that allows the customer to sort the information to detail calling patterns.

The predecessors to ATX started operations in 1985. On February 9, 2000, ATX Telecommunications Services, Ltd., its general partner A.T. Communications, Inc., Global Telecom Services, Ltd. and its general partner Global Telecommunications, Inc., merged with and into ATX Telecommunications Services, Inc., a newly-formed Delaware corporation, which was the surviving corporation.

BUSINESS STRATEGY

ATX intends to:

- PROVIDE INTEGRATED COMMUNICATIONS SERVICES AND TARGET HIGH GROWTH SECTORS. ATX offers a full complement of high-speed data and telecommunications services on a bundled and individual basis for which it provides a single bill. ATX believes that providing one-stop communications services, including local and long distance services as well as data and Internet services, will help ATX to meet the needs of its customers, penetrate its targeted markets, capture a larger portion of its customers' communications expenditures and increase customer retention. ATX is focusing on the following products in an effort to grow its revenues: local service, network data integration, Web hosting/Web development and Internet service.

64

- CONTINUE TO DEVELOP A SUPER-REGIONAL NETWORK IN COMMUNICATIONS INTENSIVE MARKETS. ATX's goal is to expand its network reach in the Northeast region.

- TARGET SMALL- AND MEDIUM-SIZED BUSINESSES. ATX will continue to target small-and medium-sized businesses, as well as Fortune 1,000 companies, in the New York-Virginia corridor. ATX believes that these customers are typically under-served by incumbent local exchange carriers and that they will value ATX's ability to provide an integrated suite of advanced telecommunications and consulting services on one bill. ATX believes that its 15-year operating history and strong presence in its region make it well-positioned to exploit this attractive market.

- EXPAND ATX'S SALES FORCE TO INCREASE REVENUE, MARKET SHARE AND GEOGRAPHIC REACH. With an experienced sales force in the New York-Virginia corridor, in an effort to expand its revenues, ATX plans to expand its sales force going forward with new offices in southern New England, southern New Jersey and New York.

- CONTINUE TO PENETRATE ENHANCED VOICE AND DATA SERVICES INTO ITS EXISTING CUSTOMER BASE. ATX cross-sells voice and data services to its existing customer base. ATX's dedicated client care specialists focus on customer service and opportunities to introduce new products to existing accounts. Compared with generating new customers, this process is less time-intensive due to existing customers' familiarity with ATX and has the ability to provide higher revenue margins because it is likely there will be lower additional sales expense. Moreover, ATX believes that providing additional services significantly increases customer retention. Since April 1998, when ATX entered the local service market, ATX has delivered local services to approximately 28% of its long distance customer base. ATX plans to focus on marketing to its existing customers its data products, including network data integration, Web hosting/Web development and Internet service.

- EXPAND SMART-BUILD NETWORK EXPANSION FOCUSED ON CLUSTERED CUSTOMER FOOTPRINT. ATX operates a capital-efficient switch and facilities-based network that utilizes highly advanced technology. From its inception, ATX has used a "smart-build" network strategy, building and owning the intelligent components of its network while leasing unbundled local loops and inter-exchange transport facilities from other carriers. The purpose of this strategy is to allow ATX to enter new markets rapidly, selectively target customer clusters, provide low cost redundancy, and generate cash flow quickly, while minimizing capital expenditures. As a result, approximately 90% of total ATX traffic originates and approximately 75% of ATX traffic terminates on its network.

PRODUCTS AND SERVICES

ATX offers its customers a full range of broadband communications services. ATX's current product offerings include:

Long distance. ATX has offered switched and dedicated long distance services since its inception in 1985. Long distance services include inbound/outbound service, international, 800 or 888 service and calling card telephone service. ATX currently

New Products and Services. ATX believes that DSL, network managed services and co-location server farm for electronic commerce platforms offer significant potential for revenue growth. ATX intends to continue focusing its efforts on advancing these new products and services.

SALES, MARKETING AND DISTRIBUTION

The ATX sales model is based on its consultative sales approach, its proprietary marketing and training tools, the experience of its sales force, its "farm-team" training

66

and career development program, and its shared vision and incentive structure to reward individual and team performance objectives.

Each ATX sales consultant provides value to the customer by tailoring telecommunications products that meet the specific needs of the customer. Each sale begins with an evaluative consultation that investigates the telecom needs of the customer. The ATX sales consultant then designs a tailored, integrated and cost-effective telecom platform that addresses the specific customer's communications needs. The level of the sales consultant's telecom and customer knowledge necessary to sell successfully can be achieved only through significant training, mentoring and devotion of corporate resources.

ATX has an experienced and long-tenured sales force. Over 25% of ATX's senior sales force professionals have been with ATX for more than 5 years, and 18 out of 22 members of the sales management team have been promoted from within the ATX organization. ATX's 243 sales personnel are organized in ten teams, including sales consultants at all levels.

CUSTOMERS AND PROPRIETARY SYSTEMS

Customers. Approximately ninety percent of ATX's customers are located in the New York-Virginia corridor. No single customer represents more than 2% of total sales. These customers are typically under-served by the incumbent local exchange carrier and value ATX's ability to provide an integrated complement of advanced telecommunications and consulting services on one bill. All of ATX's revenues are from end-users, with no wholesale, carrier or reciprocal compensation revenues. In addition, a large portion of ATX's customers are in industries, such as health services, insurance, legal services, banking and transportation, that have a high demand for data intensive and comprehensive telecommunication services.

Management Information Systems. ATX has invested in the construction of a series of proprietary software applications and an extensive corporate Intranet in its efforts to achieve a paperless work environment in which all job critical information is readily available online. ATX's employees can use the corporate Intranet to access detailed product and corporate information, industry research and updates, competitive intelligence files, online training and certification, calendars, a personnel directory,

67

community activities, philanthropic organizations, and other important content from the convenience of their desktops. Online forms and sophisticated e-mail applications have further increased productivity by enhancing communications at ATX.

ATX currently utilizes internally developed proprietary systems for integrated order management and provisioning, as well as for customer relations management. For billing, ATX uses a combination of an external service bureau and proprietary software.

ATX NETWORK ARCHITECTURE

ATX employs a "smart build" network architecture for the delivery of local and long distance telephony and data services. Since its predecessors' inception, ATX has invested capital in switching and networking technologies. ATX's growth has been through deliberate, planned expansion, resulting in an efficient heterogeneous, interconnect network connecting the major metropolitan service areas throughout North America. ATX's network development strategy has focused around high-density commercial zones where ATX gains control of the "last mile" of fiber or copper loop via a potential build or a lease. This "last mile" ultimately connects each customer to the ATX network, which ATX believes creates a desirable customer dynamic that affords operating efficiencies and results in higher customer retention rates.

ATX believes that, in the future, a significant amount of telecommunications traffic will utilize packet switching technologies. The current and emerging technologies provide for the encapsulation of all types of telecommunications services within a common packet switched protocol. As a result, ATX is currently developing its network towards an Internet network, packet switched, centric model.

COMPETITION

The telecommunications industry and all of its segments are highly competitive and many of ATX's existing and potential competitors have greater financial, marketing, technical and other resources than does ATX. ATX faces heavy competition in the telecommunications industry for all of the services it currently provides and those it intends to provide in the future. Competition for ATX's products and services is based on price, quality, network reliability, service features and responsiveness to customers' needs. ATX's strongest competitors in the long distance market are AT&T and MCI-WorldCom, and to a lesser degree, emerging competitive local exchange carriers. In the local market, ATX's strongest competitors are AT&T (Teleport), MCI-WorldCom (MFS) and Bell Atlantic. In the Internet connectivity market, MCI-WorldCom, Sprint and some local Internet service providers offering dial-up connectivity in the small business segment represent ATX's strongest competition. ATX's primary competitors in the Web development market are local Web development companies. Competition is relatively strong in the areas of network integration and integrated access. In other markets, such as data communications and wireless, ATX faces relatively strong competition.

EMPLOYEES

As of June 30, 2000, ATX had approximately 600 employees, none of whom are represented by a labor union or are members of a collective bargaining unit.

ATX's headquarters/executive offices and primary technical operations facility are leased from entities controlled by Michael Karp, the Chief Executive Officer and principal stockholder of ATX. ATX currently pays approximately $1.0 million per year in rent for its headquarters/executive offices and approximately $450,000 per year in rent for its primary technical operations facility. The lease for ATX's headquarters/executive offices expires in January 2004, and ATX has an option to renew the lease for an additional five years. The lease for ATX's primary technical operations facility expires in December 2002. All of ATX's sales offices and the smaller technical operations facility are leased. ATX pays a total of approximately $425,000 per year in rent for its sales offices and the smaller technical operations facility. The leases for ATX's sales offices and the smaller technical operations facility expire between August 2001 and March 2005. ATX has options to renew certain of these leases.

GOVERNMENT REGULATION OF
THE TELECOMMUNICATIONS SERVICES BUSINESS

The following section describes government regulation that is applicable to the businesses of CoreComm, Voyager, ATX and post-merger CoreComm.

OVERVIEW

Many of the telecommunications services that post-merger CoreComm, CoreComm, Voyager and ATX currently provide and will provide in the future are regulated by federal, state and local government agencies. The following summary does not purport to describe all current and proposed regulations and laws affecting the telecommunications industry. Other existing federal and state regulations and legislation are the subject of judicial proceedings, legislative hearings and administrative proposals, which could change in varying degrees the manner in which this industry operates. Neither the outcome of these proceedings nor their impact on the telecommunications industry or our business can be determined at this time. Future federal or state regulations and legislation may be less favorable to us than current regulation and legislation and therefore may have a material and adverse impact on our business and financial prospects. In addition, we may expend significant financial and managerial resources to participate in proceedings setting rules at either the federal or state level, without achieving a favorable result.

At the federal level, the FCC has jurisdiction over interstate and international services. Interstate services are communications that originate in one state and terminate in another. State public service commissions exercise jurisdiction over intrastate services, which are communications that originate and terminate in a single state. Municipalities and other local government agencies may also regulate limited aspects of post-merger CoreComm's business, such as the use of government-owned rights-of-way and construction permits. Post-merger CoreComm's networks also may have to comply with numerous local regulations such as building codes, franchise and right-of-way licensing requirements.

TELECOMMUNICATIONS ACT OF 1996

The Telecommunications Act of 1996 has resulted and will continue to result in substantial changes in the marketplace for telecommunications services. These changes include opening local exchange services to competition and a substantial increase in the addressable services for us. Among its more significant provisions, the Telecommunications Act:

- removes legal barriers to entry into all telecommunications markets, including long distance and local exchange services;

- requires incumbent local exchange carriers, such as SBC or Bell South, to "interconnect" with and provide telecommunications services for resale by competitors;

70

- permits incumbent local exchange carriers, including Bell regional operating companies in some circumstances to enter into new markets, such as long distance and cable television;

- relaxes regulation of telecommunications services provided by incumbent local exchange carriers and all other telecommunications service providers; and

- directs the FCC to establish an explicit subsidy mechanism for the preservation of universal service.

The FCC was also directed by Congress to revise and make explicit subsidies inherent in the access charge paid by inter-exchange carriers for use of local exchange carriers' services.

REMOVAL OF ENTRY BARRIERS

The provisions of the Telecommunications Act enable post-merger CoreComm to provide a full range of telecommunications services in any state. Although post-merger CoreComm will be required to obtain certification from state public service commissions in almost all cases, the Telecommunications Act limits substantially the ability of a state public service commission to deny a request for certification. The provisions of the Telecommunications Act also reduce the barriers to entry by other potential competitors and therefore increase the level of competition post-merger CoreComm will likely face in all markets affected by the Telecommunications Act. Please refer to the section of this joint proxy statement and prospectus entitled "Risk Factors -- Risk factors relating to post-merger CoreComm's business."

INTERCONNECTION WITH LOCAL EXCHANGE CARRIER FACILITIES

A company cannot compete effectively with the incumbent local exchange carriers in the switched local telephone services market unless it is able to connect its facilities with the incumbent local exchange carriers' facilities and obtain access to essential services and resources under reasonable rates, terms and conditions. The Telecommunications Act places a number of access and interconnection requirements on all local exchange providers, including competitive local exchange carriers, with additional requirements placed on incumbent local exchange carriers. These requirements are intended to provide access to networks under reasonable rates, terms and conditions. Specifically, incumbent local exchange carriers must provide the following:

Separation of Network Elements. Incumbent local exchange carriers must offer access to various parts of their network on a separate basis. This requirement allows new competitors such as us to purchase at cost-based rates elements of an incumbent local exchange carrier's network that may be necessary to provide service to our customers.

Dialing Parity. All local exchange carriers must provide dialing parity, which means that a customer calling to or from a competitive local exchange carrier network cannot be required to dial more digits than is required for a comparable call originating and terminating on the incumbent local exchange carriers' network.

71

Telephone Number Portability. Telephone number portability enables a customer to keep the same telephone number when the customer switches local exchange carriers.

Reciprocal Compensation. The duty to provide reciprocal compensation means that local exchange carriers must terminate calls that originate on competing networks in exchange for a cost based level of compensation and that they are entitled to termination of calls that originate on their network at the same level of compensation.

Resale. Local exchange carriers generally may not prohibit or place unreasonable restrictions on the resale of their telecommunications services. In addition, incumbent local exchange carriers must offer these services to resellers at a wholesale rate that is less than the retail rate charged to end users.

Collocation. Subject to space and equipment use limitations, incumbent local exchange carriers must permit competitive local exchange carriers to install and maintain certain types of their own network equipment in incumbent local exchange carriers' central offices and remote terminals. The rates, terms and conditions are subject to negotiation and, failing agreement, to arbitration before state public utilities commissions.

Access to Rights-of-Way. All incumbent local exchange carriers, competitive local exchange carriers and certain other utilities must provide access to their poles, ducts, conduits and rights-of-way on a reasonable, nondiscriminatory basis.

Incumbent local exchange carriers are required to negotiate in good faith with other carriers that request any or all of the arrangements discussed above. If a requesting carrier is unable to reach agreement with the incumbent local exchange carriers within a prescribed time, either carrier may request arbitration by the applicable state commission.

The rates charged by incumbent local exchange carriers for interconnection and separate network elements must be calculated using a forward-looking, incremental cost methodology, but may still vary greatly from state to state. These rates must be approved by state regulatory commissions, often following a lengthy and expensive negotiation, arbitration, and review process. Recurring and non-recurring charges for local loops and other separate network elements may change based on the rates proposed by incumbent local exchange carriers and approved by state regulatory commissions from time to time, which creates uncertainty about how interconnection and separate element rates will be determined in the future and which could have an adverse effect on our operations. In January 1999, the United States Supreme Court upheld the FCC's authority to adopt national pricing rules for interconnection services, unbundled network elements, and resale by competitive local exchange carriers. The Supreme Court left open, however, the question of the legality of the total element long-run incremental pricing methodology adopted by the FCC. On July 18, 2000, the United States Court of Appeals for the Eighth Circuit vacated and remanded several of the FCC's pricing rules, which may require the FCC to implement a new pricing methodology that may be less

72

favorable to competitive local exchange carriers. For example, the Eighth Circuit overturned the FCC's pricing rule that required the total element long-run incremental cost of an element to be measured based on the use of the "most efficient telecommunications technology currently available and the lowest cost network configuration." The Eighth Circuit did, however, find that the use of a forward-looking incremental cost methodology is reasonable. Portions of the Eighth Circuit's July 2000 ruling may be appealed to the Supreme Court.

While the Telecommunications Act generally requires incumbent local exchange carriers to offer interconnection, separate network elements and resold services to competitive local exchange carriers, incumbent local exchange carriers-to-competitive local exchange carriers interconnection agreements may have short terms, requiring the competitive local exchange carriers to renegotiate the agreements. In addition, incumbent local exchange carriers may not provide timely provisioning or adequate service quality, thereby impairing a competitive local exchange carrier's reputation with customers who can easily switch back to the incumbent local exchange carriers. In January 1999, the United States Supreme Court upheld the FCC's authority to adopt national pricing rules for interconnection services, separate network elements, and resale by competitive local exchange carriers.

On remand from the Supreme Court's January 1999 decision, the FCC adopted an order on September 15, 1999, which specified the separate elements that incumbent local exchange carriers must make available to competitors. The FCC reaffirmed that incumbents must provide separate access to six of the seven network elements that were listed in the FCC's 1996 order. According to the FCC, separate access to the seventh item, operator and directory assistance services, is no longer necessary to facilitate competition. The FCC's order also added additional separate elements to the list -- subloops, portions of loops and dark fiber -- but declined, except in limited circumstances, to require incumbent local exchange carriers to separate the facilities used exclusively to provide high-speed Internet access and other data services. In addition, the FCC initiated a further rulemaking proceeding to consider whether carriers should be able to combine separate elements to provide special access services in competition with those provided by the incumbent local exchange carriers. Portions of the FCC's 1999 ruling have been appealed by several parties.

In February 1999, the FCC determined that calls to Internet service providers are interstate in nature, thus falling under the FCC's jurisdiction and outside the scope of the Telecommunications Act's reciprocal compensation requirements. The FCC initiated a review of compensation arrangements for calls to Internet service providers but stated that, in the meantime, parties may voluntarily include reciprocal compensation provisions in their interconnection agreements and that state commissions may order compensation for termination of Internet service provider calls. Many states decided to leave intact existing decisions in favor of reciprocal compensation for Internet service provider-bound calls. On March 24, 2000, the U.S. Court of Appeals for the D.C. Circuit overturned the FCC's decision that calls to Internet service providers are not local. The court found that the FCC had failed to explain adequately its determination that a call does not

73

"terminate" at an Internet service provider merely because the Internet service providers then originate further telecommunications that extend beyond state boundaries. In response to this court ruling, the FCC could restate its original jurisdictional conclusion, it could determine that calls to Internet service providers are local, or it could create a new classification for them. If it concludes that such calls are local, competitive local exchange carriers could be entitled to reciprocal compensation under the Telecommunications Act for terminating Internet service provider-bound traffic, which could have a favorable impact on our revenues. Such a decision, however, could also potentially lead to more state control over Internet-related services, which could have a negative effect on our roll out of such services. Legislation has been introduced in Congress that would declare Internet traffic not to be subject to reciprocal compensation. Enactment of such a provision could have an adverse effect on our revenues.

Several incumbent local exchange carriers have filed petitions at the FCC and have initiated legislative efforts to effect a waiver of the obligation to unbundle and offer services for resale with regard to high-speed data or "advanced" services. In addition, certain incumbent local exchange carriers are seeking to provide these services on an interLATA (long distance) basis before they have been granted approval by the FCC pursuant to Section 271 of the Telecommunications Act to enter the long distance market. Permitting incumbent local exchange carriers to provision data services through separate affiliates with fewer regulatory requirements could have a material adverse impact on our ability to compete in the data services sector. The FCC imposed conditions on the merger of SBC with Ameritech in October 1999 and on the merger of Bell Atlantic and GTE in June 2000 that permit the provisioning of advanced data services via separate subsidiaries under various requirements, some of which expire in the near term. We cannot predict whether these requirements are enforceable, nor whether they will deter anticompetitive behavior if they are enforceable. Bell Atlantic's, now Verizon's, application for long distance service in New York and SBC's application for long distance service in Texas have been approved subject to similar separate subsidiary provisions. These areas of regulation are subject to change through additional proceedings at the FCC or upon judicial review.

Although the FCC has held that incumbent local exchange carriers providing advanced services continue to be required to comply with the resale and unbundling obligations of the Telecommunications Act, it has started a proceeding to determine whether incumbent local exchange carriers can create separate affiliates for advanced services that would be free of these obligations. In November 1999, the FCC ruled that quality discounts on tariffed digital subscriber line services that incumbent local exchange carriers provide to Internet service providers need not be resold to competitive telecommunications providers at lower wholesale rates.

The FCC has adopted rules requiring incumbent local exchange carriers to provide collocation to competitive local exchange carriers for the purpose of interconnecting their competing networks. Under the rules adopted by the Local Competition Orders, incumbent local exchange carriers are required to provide either physical collocation or virtual collocation at their switching offices. Recently, the FCC established new rules

74

designed to make it easier and less expensive for competitive local exchange carriers to obtain collocation at incumbent local exchange carrier central offices by, among other things, restricting the incumbent local exchange carriers' ability to prevent certain types of equipment from being collocated and requiring incumbent local exchange carriers to offer alternative collocation arrangements to competitive local exchange carriers. On March 17, 2000, however, the U.S. Court of Appeals for the D.C. Circuit overturned several of these collocation rules, finding that the FCC had failed to make a determination about whether all the types of equipment incumbent local exchange carriers are required to collocate is "necessary" for interconnection or access to separate elements. According to the court, such a determination is required under the Telecommunications Act. The court also rejected other FCC rules that permit competitive local exchange carriers to cross-connect their equipment with the equipment of other competitive local exchange carriers and give competitive local exchange carriers the option of collocating equipment in any unused space in an incumbent local exchange carrier central office. While ultimately the FCC could provide reasoned explanations for its current collocation requirements, the uncertainty created by this court decision could provide incumbent local exchange carriers with a basis for refusing to collocate multi-function equipment or provide collocation in a timely and efficient manner. This could have a negative impact on our network deployment plans.

In this March 17, 2000 order, the court also overturned the FCC's determination that incumbent local exchange carriers must permit collocating competitive local exchange carriers to cross-connect their facilities. The court stated that the FCC failed to explain how cross-connects between competitive local exchange carriers are necessary for interconnection with or access to the separate elements of the incumbent local exchange carriers. In addition, the court rejected some of the FCC's provisions regarding the implementation of physical collocation, such as the requirement that incumbent local exchange carriers give competitors the option of collocating equipment "in any unused space." The immediate impact of these rulings is that incumbent local exchange carriers may seek to hinder physical collocation, driving up collocation costs. The FCC will have the opportunity to offer explanations for its decisions, but these explanations may not be issued in the near future. The March 17, 2000 order did uphold FCC rules regarding cost allocation and imposing the requirement that incumbent local exchange carriers provide cageless and adjacent collocation.

On December 9, 1999, the FCC released an order that requires incumbent local exchange carriers to offer line sharing as a separate network element by June 6, 2000. Line sharing permits competitive local exchange carriers to use a customer's existing line to provide DSL services while the incumbent local exchange carrier continues to use the same line to provide voice service. Prices for line sharing will be set by the states based on a cost methodology adopted by the FCC. This decision has been appealed. In the meantime, a number of Bell regional operating companies have reached agreements to provide line sharing at no or at very low cost, subject to a true-up once the applicable state commission sets a price. These cost-based line sharing charges may improve the business outlook for our Internet-related products and services initiatives.

75

SBC, through its Project Pronto, is changing its network architecture. These changes may have an impact on CoreComm's ability to interconnect and collocate for the provision of DSL services. One of the changes is the replacement of copper lines with fiber lines in certain parts of the SBC network. Currently, many types of DSL services can be transmitted only over copper lines. Another change involves a reduction in the size of remote terminal facilities in SBC's network. This limits the space available for CoreComm and other providers to place their DSL equipment in those remote terminal facilities. SBC may also be deploying DSL-related equipment that is not compatible for interconnection with competitors' DSL equipment.

In addition to requiring the incumbent local exchange carriers to open their networks to competitors and reducing the level of regulation applicable to competitive local exchange carriers, the Telecommunications Act also reduces the level of regulation that applies to the incumbent local exchange carriers, thereby increasing their ability to respond quickly in a competitive market. For example, the FCC has applied "streamlined" tariff regulation of the incumbent local exchange carriers, which shortens the requisite waiting period before which tariff changes may take effect. These developments enable the incumbent local exchange carriers to change rates more quickly in response to competitive pressures. The FCC has also adopted heightened price flexibility for the incumbent local exchange carriers, subject to specified caps. If exercised by the incumbent local exchange carriers, this flexibility may decrease CoreComm's ability to compete effectively with the incumbent local exchange carriers in its markets.

The Telecommunications Act also gives the FCC authority to decide to forebear from regulating carriers if it believes regulation would not serve the public interest. The FCC is charged with reviewing its regulations for continued relevance on a regular basis. As a result of this mandate, a number of regulations that apply to competitive local exchange carriers have been, and others may in the future be, eliminated. We cannot, however, guarantee that any regulations that are now or will in the future be applicable to us will be eliminated.

Congress is considering a number of bills that would deregulate the provision of advanced services by incumbent local exchange carriers. These regulatory or legislative outcomes could have an adverse effect on our ability to obtain access to the network elements necessary for the provision of advanced services to our customers or to compete with incumbent local exchange carriers in the provision of such services.

LOCAL EXCHANGE CARRIER ENTRY INTO NEW MARKETS

Our principal competitor in each local exchange market we enter is the incumbent local exchange carrier. Bell regional operating companies are currently permitted to provide long distance services to customers outside of their local service areas and in conjunction with their mobile telephone service offerings, but they are prohibited from providing long distance services that originate in the states where they provide local telephone service, which is referred to as in-region long distance service. Section 271 of the Telecommunications Act established procedures under which regional Bell operating

76

companies can provide in-region long distance services in a state after receiving approval from the FCC. To obtain approval, the regional Bell operating companies must comply with a competitive checklist that incorporates, among other requirements, the interconnection requirements discussed above. Please refer to the section entitled "Government Regulation of the Telecommunications Services Business -- Interconnection with Local Exchange Carrier Facilities."

Approval under Section 271 from the FCC will enable regional Bell operating companies to provide customers with a full range of local and long distance telecommunications services. The provision of long distance services by regional Bell operating companies is expected to reduce the market share of the major long distance carriers, which may be significant customers of our services. Consequently, the entry of the regional Bell operating companies into the long distance market may have adverse consequences on the ability of competitive local exchange carriers such as us both to generate access revenues from the inter-exchange carriers and to compete in offering a package of local and long distance services. On December 22, 1999, the FCC approved an application filed by Bell Atlantic, now Verizon, seeking authority to begin providing long distance services to customers located in the State of New York. This action represented the first Section 271 approval by the FCC, which on June 30, 2000, also approved SBC's application for Section 271 authority in Texas. We anticipate that Verizon, SBC and other Bell regional operating companies will soon initiate similar proceedings to obtain long distance service authority in other states in which we operate or plan to operate. For example, Verizon already has begun the necessary regulatory review process in the Commonwealth of Massachusetts.

COMPETITIVE LOCAL EXCHANGE CARRIER INTERSTATE ACCESS CHARGES

In addition to charging other carriers reciprocal compensation for terminating local traffic, CoreComm also collects access charges from carriers for originating and terminating interexchange traffic. Some interexchange carriers, including AT&T and Sprint, have challenged the switched access rates of certain competitive local exchange carriers, and have withheld some payments for the switched access services that they continue to receive. Although no formal complaints have been filed against CoreComm, AT&T and Sprint have filed complaints against other competitive local exchange carriers asserting that such competitive local exchange carriers' service charges for switched access services are higher than those of the incumbent local exchange carriers serving the same territory, and are therefore unjust and unreasonable. These interexchange carriers have refused to pay competitive local exchange carriers any originating access charges in excess of the corresponding incumbent rate. Because CoreComm's access charges are appreciably less than those of some competitive local exchange carriers, and are lower than the access charges of smaller incumbents having traffic volumes similar to CoreComm's, CoreComm does not expect the FCC to require any appreciable reduction in CoreComm's tariffed rates. In addition, in June 2000, the FCC denied the first complaint brought by Sprint against another competitive local exchange carrier based solely on a comparison of the rates of the competitive local exchange carrier to those of incumbent local exchange carriers in the same territory.

77

RELAXATION OF REGULATION

Through a series of proceedings, the FCC has established different levels of regulation for "dominant carriers" and "non-dominant carriers." As a non-dominant carrier, we are subject to relatively limited regulation by the FCC. However, at a minimum, we must offer interstate services at just and reasonable rates in a manner that is not unreasonably discriminatory.

One goal of the Telecommunications Act is to increase competition for telecommunications services and thus reduce the need for regulation of these services. To this end, the Telecommunications Act requires the FCC to streamline its regulation of incumbent local exchange carriers and permits the FCC to forbear from regulating particular classes of telecommunications services or providers. Since post-merger CoreComm is a non-dominant carrier and, therefore, is not heavily regulated by the FCC, the potential for regulatory forbearance likely will be more beneficial to the incumbent local exchange carriers than to us in the long run.

The Telecommunications Act requires all common carriers, including us, to charge just and reasonable rates for their services and to file schedules of these rates with the FCC. These schedules are known as "tariffs" and they represent a contract between a carrier and its customers. The Telecommunications Act permits the FCC to "forbear" from enforcing certain provisions of the Telecommunications Act and the FCC has used this authority to determine that it is in the public interest to prohibit non-dominant carriers from filing tariffs for their interstate services. This decision of the FCC and its "mandatory detariffing" was recently affirmed by the U.S. Court of Appeals for the D.C. Circuit. Currently, the FCC is not permitting non-dominant carriers to file new tariffs and will require existing tariffs to be withdrawn by 2001. The FCC's preclusion of non-dominant interstate carriers from filing tariffs may increase our exposure to litigation. Currently, tariffs contain provisions limiting the liability of providers on a variety of issues. In the absence of filed tariffs, carriers would have to rely on negotiated contracts with each customer to provide these liability limitations.

Another FCC decision permits, but does not require, competitive local exchange carriers to file tariffs for the charges that they levy on interstate long distance carriers for completing calls to competitive local exchange carriers' customers. Proposals are pending before the FCC to make detariffing of access services mandatory for competitive local exchange providers. See "Government Regulation of the Telecommunications Services Business -- Universal Service and Access Charge Reform" below.

UNIVERSAL SERVICE AND ACCESS CHARGE REFORM

On May 8, 1997, the FCC issued an order implementing the provisions of the Telecommunications Act relating to the preservation and advancement of universal telephone service. This order requires all telecommunications carriers providing interstate telecommunications services, including us, to contribute to universal service support for schools, libraries and rural health care programs. Our contribution to the federal support funds is calculated based on a percentage of our gross end-user interstate and international telecommunications revenue. Although we have already begun contributing

78

to the federal universal service and high cost funds, the amount of our required contribution changes each quarter. Various states are also in the process of implementing their own universal service programs. We are currently unable to quantify the amount of subsidy payments that we will be required to make and the effect that these required payments will have on our financial condition.

On July 30, 1999, the United States Court of Appeals for the Fifth Circuit overturned some of the FCC's rules governing the collection and distribution of those payments. In October 1999, the FCC released two orders in response to the Fifth Circuit's decision. One order permits incumbent local exchange carriers to continue to recover their universal service contributions from access charges or to establish end-user charges. The second order changed the contribution basis for school/library funding to eliminate calculations based upon intrastate revenues. A number of parties have petitioned the Supreme Court to review the Fifth Circuit's decision. The Supreme Court recently agreed to decide the constitutionality of the FCC's methodology used to compute universal service support payments.

In May 1999, the FCC adopted a framework for a new, forward-looking, high-cost support mechanism that will provide support for non-rural telecommunications carriers. The FCC stated that the support mechanism will be used only to determine federal support and will not impose any obligation on a state to impose intrastate surcharges. It is not possible to determine at this time what effect this ruling will have on the level of contributions we are required to make to either the federal or various state universal service programs, or if it will become easier for us to become qualified as recipients of universal service funds when we serve high-cost areas.

In a related proceeding, on May 16, 1997, the FCC issued an order implementing reforms to its access charge rules. Access charges are charges imposed by local exchange carriers on long distance providers for access to the local exchange network, and are designed to compensate the local exchange carrier for its investment in the local network. The FCC regulates interstate access and the states regulate intrastate access. This order required incumbent local exchange carriers to substantially decrease over time the prices they charge for switched and special access and changed how access charges are calculated. These changes are intended to reduce access charges and shift certain usage-based charges to flat-rated, monthly per-line charges. To the extent that these rules are effective in reducing access charges, our ability to offer customers lower-cost access services might be impaired.

On August 27, 1999, the FCC issued an order implementing further reforms to its access charge rules. The FCC's order granted most local exchange carriers greater pricing flexibility and instituted other access charge reforms designed to increase competition and reduce access charges. These changes could impair our ability to offer customers lower-cost access services. The FCC also issued a notice of proposed rulemaking, proposing additional pricing flexibility. In addition, the FCC has initiated a proceeding to consider whether to adopt rules constraining competitive local exchange carrier access charges. To the extent competitive local exchange carrier access charges are reduced, our revenue could decrease.

79

On May 31, 2000, the FCC issued an order adopting an integrated interstate access reform and universal service proposal put forth by a coalition of incumbent local exchange carriers and inter-exchange carriers. These reforms are aimed primarily at price cap (incumbent) local exchange carriers, but it is too early to assess what impact, if any, they will have on CoreComm.

Some state public service commissions have adopted rules or are currently considering actions to preserve universal services and promote the public interest.

LOCAL GOVERNMENT AUTHORIZATIONS

Many jurisdictions where we may provide services require license or franchise fees based on a percentage of certain revenues. Because the Telecommunications Act specifically allows municipalities to charge fees for use of the public rights-of-way, it is likely that jurisdictions that do not currently impose fees will seek to impose fees in the future. However, the amount and basis of these fees have been successfully challenged by several telecommunications service providers. Federal courts have struck down municipal ordinances that:

- do not relate the fees imposed under the ordinance to the extent of a provider's use of the rights-of-way;

- do not relate the fees imposed under the ordinance to the costs incurred by the local government in maintaining the rights-of-way; or

- seek to impose fees based on a concept of the "value" of the use to the provider by relating the fees to provider revenues.

Additionally, because the Telecommunications Act requires jurisdictions to charge non-discriminatory fees to all telecommunications providers, telecommunications providers are challenging municipal fee structures that excuse other companies, particularly the incumbent local exchange carriers, from paying license or franchise fees, or allow them to pay fees that are materially lower than those that are required from new competitors such as CoreComm. A number of these decisions have been appealed and, in any event, it is uncertain how quickly particular jurisdictions will respond to the court decisions without a specific legal challenge initiated by us or another competitive local exchange carrier to the fee structure at issue.

REGULATION OF RESELLERS

The FCC has defined resale as any activity in which a party, the reseller, subscribes to the services or facilities of a facilities-based provider, or another reseller, and then reoffers communications services to the public for profit, with or without adding value. Resellers are common carriers generally subject to all rules and regulations placed on providers of the underlying services by either the FCC or the states in which they operate. The FCC has held that prohibitions on the resale of common carrier services are unjust, unreasonable, and unlawfully discriminatory in violation of the Telecommunications Act. Accordingly, all common carriers must make their services available for resale at rates, terms, and conditions that do not unreasonably discriminate against

80

resellers. The Telecommunications Act imposes the additional duty upon incumbent local exchange carriers to make their services available for resale at wholesale rates. The FCC adopted specific requirements for determining these wholesale rates for local telecommunications services. While the United States Supreme Court upheld the FCC's authority to adopt these rules, the FCC's specific pricing rules remained subject to further judicial review.

On July 18, 2000, the United States Court of Appeals for the Eighth Circuit vacated the FCC's rule that required the incumbent local exchange carriers to exclude all costs that reasonably can be avoided when an incumbent local exchange carrier provides a telecommunications service for resale at wholesale rates to a requesting carrier. The Eighth Circuit ruled that incumbent local exchange carriers should only exclude those costs that an incumbent local exchange carrier will actually avoid incurring in the future. To the extent that the cost of resale services increases as a result of this Eighth Circuit decision, our operating expenses could increase. This Eighth Circuit ruling may be appealed to the Supreme Court.

As to other telecommunications service providers, such as competitive local exchange carriers and wireless providers, there is no regulation that requires them to give discounts to resellers below the rates offered to end users of the same quantities of similar services. The FCC's requirement that wireless providers offer resale services is currently set to expire on November 24, 2002.

LOCAL MULTIPOINT DISTRIBUTION SERVICE

The FCC has established a new wireless service referred to as local multipoint distribution service. The FCC allocated two frequency blocks in each of 493 Basic Trading Areas in the United States to local multipoint distribution service: Block A with 1,150 MHz of spectrum in the 28 GHz and 31 GHz bands, and Block B with 150 MHz in the 31 GHz band. Local multipoint distribution service licenses are awarded for ten-year terms with renewal expectancies provided to licensees that make a showing of substantial service in their licensed areas.

Local multipoint distribution service may be used to provide any kind of communications service on a common carrier or non-common carrier basis. Radio frequencies in the 28 and 31 GHz bands are generally capable of only "line-of-sight" transmission and reception, may receive interference from certain weather conditions, and do not lend themselves to mobile applications. Local multipoint distribution service is expected to be used for the delivery of various broadband services to homes and offices, including telecommunications, Internet access and two-way video. At least seven other countries, including Canada and Mexico, have licensed local multipoint distribution service on either a permanent or experimental basis. Local multipoint distribution service licensees are expected to be able to provide a wide array of services, two-way capabilities and high capacity through the use of newer digital equipment and transmission mechanisms. The FCC expects that Block-A local multipoint distribution service licensees especially, by applying cellular-style frequency re-use technology to an already

81

large frequency bandwidth, have the potential to become competitors to incumbent local exchange carriers and cable operators.

In the initial auction, CoreComm won 15 Block-A licenses for Basic Trading Areas encompassing substantially all population centers in the state of Ohio, for a total bid of $25,241,133. The FCC has since granted CoreComm's 15 local multipoint distribution service licenses with an effective date of June 8, 1998.

INTERNATIONAL OPERATIONS

CoreComm already provides international resale services and may ultimately expand its operations to other countries. The FCC requires every carrier that originates international telecommunications from within the U.S., either through the use of its own facilities or on a resale basis, to secure in advance an authorization from the FCC under Section 214 of the Telecommunications Act. Additionally, these carriers must file with the FCC a tariff containing the rates, terms, and conditions of their international service offerings. CoreComm holds a Section 214 Authorization for both facilities-based and resale international services and has filed a tariff for its international resale services.

INTERNET REGULATION

The FCC currently does not regulate the provision of Internet service, although it does regulate common carriers that provide elements of the "backbone" networks on which the Internet is based. Similarly, state public utility commissions generally do not regulate Internet service, except in some limited circumstances where incumbent local exchange carriers provide Internet services. The FCC and some states, however, are reviewing the development of the Internet and the types of services that are provided through it. For example, if the FCC should determine that an Internet service provider offers a service that is an exact substitute for long distance telephone service with the sole distinction that it is based on a packet-switched network rather than a circuit- switched network, the FCC may determine that it should impose similar regulation on the new services.

STATE REGULATION GENERALLY

Most states require companies to be certified or authorized by the state's public utility commission in order to provide common carrier services. These certifications generally require a showing that the carrier has adequate financial, managerial and technical resources to offer the proposed services in a manner consistent with the public interest.

In addition to obtaining certification, in each state, we must negotiate terms of interconnection with the incumbent local exchange carrier before we can begin providing switched services. See "Government Regulation of the Telecommunication Services Business -- Interconnection with Local Exchange Carrier Facilities." State public utility commissions are required to approve interconnection agreements before they become effective and must arbitrate disputes among the parties upon request. We have already entered into interconnection agreements with Ameritech, which is now a part of SBC,

82

Cincinnati Bell Telephone and Verizon. We have also initiated the process of negotiations with SBC and Verizon for additional interconnection agreements. Regulatory changes could require renegotiation of relevant portions of existing interconnection agreements, or require additional court and regulatory proceedings.

We are not presently subject to price regulation based on costs or earnings. Most states require competitive local exchange carriers to file tariffs setting forth the terms, conditions and prices for intrastate services. Some states permit tariffs to list a rate range or set prices on an individual case basis. Other state requirements may include filing of periodic reports, the payment of regulatory fees and surcharges and compliance with service standards and consumer protection rules.

Several states provide incumbent local exchange carriers with flexibility for their rates, special contracts (selective discounting) and tariffs, particularly for services that are considered to be competitive. This pricing flexibility increases the ability of the incumbent local exchange carrier to compete with us and constrains the rates we may charge for our services. States may grant incumbent local exchange carriers additional pricing flexibility. At the same time, some incumbent local exchange carriers may request increases in local exchange rates to offset revenue losses due to competition.

Some states require prior approvals or notification for certain transfers of assets, customers or ownership of a competitive local exchange carrier and for issuance of bonds, notes or other evidence of indebtedness or securities of any nature. Delays in receiving required regulatory approvals may occur.

RECIPROCAL COMPENSATION

Reciprocal compensation is the compensation paid by one carrier to complete local calls placed by its customers to customers on another local exchange carrier's network. Because Internet service providers, such as Voyager, receive many more calls than they make, we expect that after completion of the Voyager merger, we will receive significantly more reciprocal compensation than we will pay. However, as a result of uncertainties in the current regulatory environment and several trends in the telecommunications business, which are discussed below, it is not clear by how much CoreComm's revenues from reciprocal compensation will increase over the next few years.

Some incumbent local exchange carriers have refused to pay reciprocal compensation charges that they claim are the result of Internet service provider traffic because they believe that this type of traffic is outside the scope of existing interconnection agreements. On February 26, 1999, the FCC issued a declaratory ruling and Notice of Proposed Rulemaking concerning Internet service provider traffic. The FCC concluded in that ruling that Internet service provider traffic is jurisdictionally mixed and largely interstate in nature, and thus within the FCC's jurisdiction. However, the FCC also determined that there was no federal rule that governed reciprocal compensation for Internet service provider traffic at the time that the then-existing interconnection agreements were negotiated and concluded that it should permit states to determine whether reciprocal compensation should be paid for calls to Internet service providers under existing interconnection agreements. The FCC requested comment as to what

83

reciprocal compensation rules should govern this traffic upon expiration of existing interconnection agreements.

In light of the FCC's order, state commissions which have previously addressed this issue and required reciprocal compensation to be paid for Internet service provider traffic may reconsider and may modify their prior rulings. Some recent state regulatory commission decisions regarding reciprocal compensation calls placed to Internet service providers could result in lower revenues for competitive local exchange carriers, including us, in those states. The issue remains undecided in various other states. Several incumbent local exchange carriers, including SBC and Verizon, are seeking to overturn prior orders that they claim are inconsistent with the FCC's February 26, 1999 order. The relief they seek includes repayment of reciprocal compensation amounts they previously paid. The great majority of the state commissions that have considered the issue since the FCC's February 26, 1999 order have rejected the incumbent local exchange carriers' arguments and required them to pay reciprocal compensation for Internet service provider-bound traffic. Only a small minority of the state commissions that have considered the issue are not requiring reciprocal compensation for this traffic, at least pending negotiations and a further FCC decision. A few states are not requiring current payment, but are requiring a true-up if necessary at the time of the FCC's future decision. In addition, all of the federal courts that have reviewed this issue on the merits have upheld state decisions requiring that reciprocal compensation be paid for internet service provider-bound traffic.

On March 24, 2000, the U.S. Court of Appeals for the District of Columbia Circuit vacated the FCC's declaratory ruling that Internet-bound calls, including Internet service provider calls, are jurisdictionally interstate and therefore not local calls for which reciprocal compensation is owed. The Court remanded the proceeding to the FCC for a further review of the nature of these calls for purposes of reciprocal compensation. CoreComm cannot predict the impact of the Court's ruling on pending or future proceedings at this time. In May 2000, the Illinois Commerce Commission, in an interconnection arbitration, reaffirmed its prior holding that Internet service provider calls are local and subject to payment of reciprocal compensation. However, the Illinois Commerce Commission at the same time opened a general proceeding to examine the issues surrounding the explosion of Internet traffic and its effect on the issue of reciprocal compensation. A finding that reciprocal compensation is not payable for Internet service provider traffic in Ohio, Illinois or New York would have an adverse effect on our future revenues and business strategy.

As our existing interconnection agreements expire and as we enter new markets, we must negotiate new reciprocal compensation rates and traffic scope with each incumbent carrier. We expect that rates for Internet service provider reciprocal compensation will be lower under new interconnection agreements than under our existing agreements. A reduction in rates payable for Internet service provider reciprocal compensation could have an adverse effect on our future revenues and business strategy.

THE CORECOMM SPECIAL MEETING

Voting Rights; Votes Required for Approval. The CoreComm board of directors has fixed the close of business on August 11, 2000 as the record date for the determination of the CoreComm shareholders entitled to notice of the CoreComm special meeting. On August 11, 2000, there were 40,162,454 common shares of CoreComm, which were held of record by 320 holders. As of July 13, 2000, CoreComm's directors and executive officers and their affiliates beneficially owned an aggregate of 6,740,437 common shares of CoreComm (excluding common shares reserved for options), or approximately 22.49% of the outstanding shares of CoreComm entitled to vote on the proposals.

The presence, either in person or by proxy, of the holders of a majority of the outstanding common shares of CoreComm is necessary to constitute a quorum at the CoreComm special meeting. Assuming the existence of a quorum, the affirmative vote of the holders of a majority of CoreComm's outstanding common shares voting at that meeting is required to approve and adopt the Voyager merger agreement, approve and adopt the ATX merger agreement, approve the domestication merger, approve and adopt the domestication merger agreement and approve the increase in CoreComm's authorized share capital. Holders of record of CoreComm common shares on the CoreComm record date are entitled to one vote per common share of CoreComm at the CoreComm special meeting.

If a shareholder attends the CoreComm special meeting, that shareholder may vote by ballot. However, since many shareholders may be unable to attend the CoreComm special meeting, those shareholders can ensure that their shares are voted at the meeting by signing and dating the enclosed proxy card and returning it in the envelope provided. When a proxy card is returned properly signed and dated, the CoreComm shares represented by that proxy card will be voted in accordance with the instructions on the proxy card.

Shareholders are urged to mark the box on the proxy card to indicate how their CoreComm common shares are to be voted. If a shareholder returns a signed proxy card but does not indicate how that shareholder's CoreComm shares are to be voted, the CoreComm shares represented by the proxy card will be voted "FOR" all of the proposals. The proxy card also confers discretionary authority on the individuals appointed by the CoreComm board of directors and named on the proxy card to vote the CoreComm shares represented on the proxy card on any other matter that is properly presented for action at the CoreComm special meeting, including any adjournments or postponements of the special meeting. That discretionary authority will not be used to vote for adjournment of the CoreComm special meeting to permit further solicitation of proxies if the shareholder votes against any proposal.

86

Any CoreComm shareholder who executes and returns a proxy card may revoke the proxy at any time before it is voted by:

- delivery to the Secretary of CoreComm, prior to the special meeting, a written notice of revocation bearing a later date or time than the proxy;

- granting a subsequent proxy; or

- appearing in person and voting at the CoreComm special meeting.

Attendance at the CoreComm special meeting will not in and of itself constitute revocation of a proxy.

Solicitation of Proxies. CoreComm will bear its own costs of solicitation of proxies. The cost of preparing, printing and mailing this joint proxy statement and prospectus will be paid by the party incurring those expenses. Brokerage houses, fiduciaries, nominees and others will, upon request, be reimbursed for their out-of-pocket expenses in forwarding proxy materials to owners of CoreComm common shares held in their names. In addition to the solicitation of proxies by use of the mails, proxies may be solicited from CoreComm shareholders by directors, officers and employees of CoreComm in person or by telephone, telegraph, facsimile or other appropriate means of communication. No additional compensation, except for reimbursement of reasonable out-of-pocket expenses, will be paid to these directors, officers and employees of CoreComm in connection with the solicitation. In addition, D.F. King & Co., a proxy solicitation firm, has been engaged by CoreComm to act as proxy solicitor and will receive fees estimated at $10,000, plus reimbursement of out-of-pocket expenses. Any questions or requests for assistance regarding this joint proxy statement and prospectus and related proxy materials may be directed to:

Other Matters. CoreComm is not aware of any business or matter other than those indicated above that may be properly presented at the CoreComm special meeting. If, however, any other matter properly comes before the CoreComm special meeting, the proxy holders will, in their discretion, vote on it in accordance with their best judgment. Any proposal by a shareholder intended to be presented at the 2001 annual meeting of shareholders must have been received by CoreComm at the address listed above not later than December 28, 2000 for inclusion in CoreComm's proxy statement and form of proxy relating to CoreComm's 2001 annual meeting of shareholders. CoreComm's board of directors will review any shareholder proposals that are filed as required, and will determine whether those proposals meet the criteria for inclusion in the proxy solicitation materials or for consideration at the 2001 annual meeting. Copies of CoreComm's bylaws are available to shareholders free of charge upon request to Amy Minnick, Associate

87

Director of CoreComm's Investor Relations. CoreComm retains discretion to vote proxies on matters of which it is not properly notified.

THE VOYAGER SPECIAL MEETING

Voting Rights; Votes Required for Approval. The Voyager board of directors has fixed the close of business on August 15, 2000, as the record date for the determination of the Voyager stockholders entitled to notice of and to vote at the Voyager special meeting. On August 15, 2000, there were 31,654,758 Voyager common shares outstanding, which were held of record by 94 holders. As of August 15, 2000, Voyager's directors and executive officers beneficially owned an aggregate of 20,837,577 shares of Voyager common stock (excluding shares reserved for options), or approximately 65.8% of the outstanding Voyager common stock entitled to vote on the merger proposal, which requires the affirmative vote of a majority of Voyager's outstanding shares of common stock voting together as a single class. In connection with the execution of the Voyager merger agreement, certain principal stockholders of Voyager, beneficially owning 63.9% of the outstanding shares of Voyager common stock, agreed to vote in favor of the Voyager merger agreement, thus assuring that the Voyager merger will be approved by the Voyager stockholders and therefore those principal stockholders have sufficient voting power to assure adoption of the Voyager merger agreement. Please refer to the section of this joint proxy statement and prospectus entitled "The Merger Agreements -- The Merger Agreement between CoreComm and Voyager -- Related Agreements -- The Voting Agreement" for more information regarding the agreements of the principal stockholders of Voyager and a description of the rights granted to CoreComm.

The presence, either in person or by proxy, of the holders of a majority of the outstanding Voyager shares is necessary to constitute a quorum at the Voyager special meeting. Assuming the existence of a quorum, the affirmative vote of the holders of at least a majority of the issued and outstanding shares of Voyager common stock is required to approve the merger with CoreComm. Holders of record of Voyager common stock on the Voyager record date are entitled to one vote per share at the Voyager special meeting.

If a stockholder attends the Voyager special meeting, that stockholder may vote by ballot. However, since many stockholders may be unable to attend the Voyager special meeting, the Voyager board of directors is soliciting proxies so that each holder of Voyager common stock on the Voyager record date has the opportunity to vote on the proposals to be considered at the Voyager special meeting. The Voyager common stock represented by a properly signed, dated and returned proxy card will be voted in accordance with the instructions on the proxy card. WITH RESPECT TO ADOPTION OF THE MERGER AGREEMENT WITH CORECOMM, IF A STOCKHOLDER DOES NOT RETURN A SIGNED PROXY CARD, THAT STOCKHOLDER'S VOYAGER COMMON STOCK WILL NOT BE VOTED AND THUS WILL HAVE THE EFFECT OF A VOTE "AGAINST" THE PROPOSAL. SIMILARLY, A BROKER NON-VOTE OR AN ABSTENTION WILL HAVE THE EFFECT OF A VOTE "AGAINST" THE PROPOSAL.

Stockholders are urged to mark the box on the proxy card to indicate how their shares of Voyager common stock are to be voted. If a stockholder returns a signed proxy

88

card, but does not indicate how their shares of Voyager common stock are to be voted, the Voyager common stock represented by the proxy card will be voted "FOR" all of the proposals. The proxy card also confers discretionary authority on the individuals appointed by the Voyager board of directors and named on the proxy card to vote the Voyager common stock represented thereby on any other matter that is properly presented for action at the Voyager special meeting, including any adjournments or postponements of the special meeting. That discretionary authority will not be used to vote for adjournment of the Voyager special meeting to permit further solicitation of proxies if the stockholder votes against any proposal.

Any Voyager stockholder who executes and returns a proxy card may revoke the proxy at any time before it is voted by:

- delivery to the Secretary of Voyager.net, Inc. at 4660 S. Hagadorn Road, Suite 320, East Lansing, Michigan 48823, prior to the special meeting, of a written notice of revocation bearing a later date or time than the proxy;

- granting a subsequent proxy; or

- appearing in person and voting at the Voyager special meeting.

Attendance at the Voyager special meeting will not in and of itself constitute revocation of a proxy.

Solicitation of Proxies. Voyager will bear its own costs of solicitation of proxies. The cost of preparing, printing and mailing this joint proxy statement and prospectus will be paid by the party incurring those expenses. Brokerage houses, fiduciaries, nominees and others will, upon request, be reimbursed for their out-of-pocket expenses in forwarding proxy materials to owners of Voyager common shares held in their names. In addition to the solicitation of proxies by use of the mails, proxies may be solicited from Voyager stockholders by directors, officers and employees of Voyager in person or by telephone, telegraph, facsimile or other appropriate means of communication. No additional compensation, except for reimbursement of reasonable out-of-pocket expenses, will be paid to these directors, officers and employees of Voyager in connection with the solicitation. Any questions or requests for assistance regarding this joint proxy statement and prospectus and related proxy materials may be directed to:

STOCKHOLDER PROPOSALS

Voyager will hold an annual meeting of stockholders in the year 2000 only if the Voyager merger has not been completed. Voyager will publicly announce the date of such meeting once it has been set. Under the rules of the SEC relating to when a

89

company must include a stockholder's proposal in its proxy statement, stockholder proposals intended to be included in the Voyager 2000 proxy statement must be received at Voyager's principal executive offices no later than the 10th day following the date on which Voyager publicly announces the date of such meeting. Additionally, under the provisions of the Voyager by-laws relating to nominations of persons for election to the Voyager board of directors and the proposal of business, stockholder nominations and proposals eligible to be considered at the Voyager 2000 annual meeting must be received at Voyager's principal executive offices no later than the 10th day following the date on which Voyager publicly announces the date of such meeting.

Other Matters. Voyager is not aware of any business or matter other than those indicated above that may be properly presented at the Voyager special meeting. If, however, any other matter properly comes before the Voyager special meeting, the proxy holders will, in their discretion, vote thereon in accordance with their best judgment. Copies of Voyager's by-laws are available to stockholders free of charge upon request to Voyager's Investor Relations Department. Voyager retains discretion to vote proxies on matters of which it is not properly notified.

THE MERGER TRANSACTIONS

THE MERGER BETWEEN CORECOMM AND VOYAGER

BACKGROUND OF THE MERGER BETWEEN CORECOMM AND VOYAGER

In January, 1998, Voyager retained Chase Securities, Inc. to evaluate strategic alternatives for Voyager, including the possible sale of Voyager which, at the time, was privately held. Chase set up an auction process for exploring these alternatives that continued for approximately a month and a half. During this auction process in which Chase contacted CoreComm for their possible interest in such a transaction. On March 16, 1999, CoreComm submitted a preliminary, non-binding indicative expression of interest to acquire Voyager. CoreComm and Voyager did not enter into a transaction at that time due to differences as to the valuation of Voyager. Following the auction process, Voyager's management decided not to sell Voyager and went ahead with an initial public offering in July 1999.

On December 15, 1999, Christopher P. Torto, Voyager's Chief Executive Officer, was contacted by Albert E. Schneider III, a CoreComm consultant, to reintroduce CoreComm to Voyager and discuss possible ways in which CoreComm and Voyager could cooperate. A meeting was scheduled for December 20, 1999 at Voyager's offices in East Lansing, Michigan.

On December 20, 1999, Mr. Torto and Glenn Friedly, Voyager's chairman, met with Mr. Schneider at Voyager's offices. At the meeting, the parties discussed various potential scenarios for cooperation, including a potential merger of the companies.

On December 21, 1999, in light of its preliminary discussions with CoreComm and its recognition of the significant consolidation occurring in the Internet services providers market, Voyager engaged Morgan Stanley Dean Witter & Co. Incorporated to explore the possibility of pursuing a strategic business combination or possible sale of Voyager.

On January 17, 2000, Messrs. Torto and Friedly met with Barclay Knapp, CoreComm's Chief Executive Officer, Patty Flynt, CoreComm's Chief Operating Officer, Michael Peterson of CoreComm's Corporate Development group and Mr. Schneider, in New Brunswick, New Jersey for an introductory meeting and to discuss possible business combinations.

On January 28, 2000, representatives of CoreComm met with Mr. Torto at Voyager's offices in order to perform operational due diligence on Voyager.

On January 30, 2000, Mr. Torto met in Atlanta, Georgia, with executives of a major Internet service provider to discuss a possible acquisition of Voyager by that company.

During the month of January 2000, Morgan Stanley contacted eleven parties, including a larger Internet service provider, regarding the possible acquisition of Voyager. Following this contact, a second larger Internet service provider expressed an interest in Voyager and requested due diligence materials to further evaluate a potential acquisition.

On February 2, 2000, Messrs. Torto and Friedly and a representative of Morgan Stanley, met with Mr. Knapp, Ms. Flynt, Mr. Peterson and Mr. Schneider at

91

CoreComm's offices in Cleveland, Ohio. At the meeting, the parties discussed the various operating strategies of the two companies.

On February 3, 2000, Voyager received an oral proposal from the second major Internet service provider to acquire Voyager. This proposal included common stock of the second major Internet service provider issued at an exchange ratio that reflected a ten percent premium to the exchange ratio based on the then-prevailing market price of Voyager stock and did not include any cash component. In addition, the second major Internet service provider demanded exclusivity rights for a period of two weeks. Voyager's management felt that the proposal was inadequate and that the request for exclusivity was inappropriate in light of the preliminary status of the discussions between the parties.

On February 9, 2000, Goldman, Sachs & Co. was engaged by CoreComm to undertake a study to render an opinion as to the fairness to CoreComm of the possible acquisition of all or a portion of the stock or assets of Voyager.

On February 10, 2000, at a regularly scheduled meeting, the Voyager board of directors discussed at length various growth strategies that might be available to Voyager. The strategies included possible business combinations with CoreComm, the two Internet service providers that had already contacted Voyager and other companies. The Voyager board instructed management to continue to explore strategic combinations with interested parties.

On February 15, 2000, representatives of CoreComm met with Chris Michaels, Voyager's Chief Technology Officer, in East Lansing, Michigan. The purpose of the meeting was to conduct further due diligence on Voyager's operations.

Following execution of confidentiality agreements with each of the second Internet service provider and CoreComm, the parties and their attorneys and accountants conducted due diligence between February 18-22. Legal counsel for Voyager began the preparation of preliminary documentation for each of the proposed business combinations.

On February 21, 2000, Mr. Schneider met with Mr. Torto in East Lansing, Michigan to discuss a preliminary term sheet for a transaction with CoreComm. The main items discussed were valuation, form of consideration, lock-up issues and numerous employee issues, including the vesting of stock options under Voyager's stock option plan.

On February 25, 2000, representatives of Voyager visited CoreComm's offices in Cleveland to conduct due diligence on CoreComm's operations.

During the month of February 2000, Morgan Stanley continued discussions with the two Internet service providers that had already contacted Voyager regarding the potential sale of Voyager. The second Internet service provider did not substantially change its offer, which Voyager's management believed to be inadequate. The first Internet service provider never made a formal offer to acquire Voyager. Of the other nine other parties contacted by Morgan Stanley, none made a formal offer to acquire Voyager.

A draft of a proposed merger agreement was sent to CoreComm on March 1, 2000 by Voyager's counsel. CoreComm's counsel began reviewing the draft at that time.

On March 2, 2000, Mr. Peterson, on behalf of CoreComm, forwarded proposed terms for a strategic business combination to Mr. Torto. The proposal contemplated that CoreComm would acquire 100% of the outstanding capital stock of Voyager through a merger. The proposed terms offered consideration of $15.00 per share for all of the outstanding shares of Voyager, with $3.00 to be paid in cash and $12.00 to be paid in CoreComm common shares. In addition, CoreComm requested a two week period of exclusivity. The letter setting forth the CoreComm proposal provided that unless it was accepted by March 3, 2000, it would be withdrawn.

On March 3, 2000, the Voyager board of directors met in New York, New York. Mr. Torto described the CoreComm proposal to the Voyager board. Voyager's legal and financial advisors discussed the process and the CoreComm proposal. It was agreed that Voyager management would pursue further discussions with CoreComm regarding the proposed business combination.

On March 4, 2000, Messrs. Friedly, Torto and John Hayes, a member of Voyager's board of directors, met telephonically with their legal advisors and Morgan Stanley to further discuss the structure and terms of the proposed transaction with CoreComm. During discussions between representatives of Morgan Stanley and CoreComm on March 4, 2000, after being told by Voyager that the $15.00 per share offered by CoreComm was inadequate to enter into a transaction, CoreComm increased the offered consideration to $16.00 per share for all of the outstanding shares of Voyager, with $3.00 to be paid in cash and $13.00 to be paid in CoreComm common shares. At that time it was agreed that management would continue the discussions with CoreComm. It was arranged that the parties along with their legal and financial advisors would meet in New York, New York on March 5, 2000.

On March 5, 2000, the parties along with their legal and financial advisors, met in New York, New York to discuss the general structure and terms of the proposed transaction. During this meeting, CoreComm proposed a one week period of exclusivity. After a lengthy discussion of the material issues that would be presented by such a transaction, Voyager agreed to an exclusivity period until Friday, March 10, 2000 at 12:00 noon. CoreComm's counsel continued their review of the draft Voyager merger agreement and related documents and provided a revised draft reflecting their comments. The parties agreed to a meeting the following day to discuss the terms of the proposed transaction in more detail. Although at this point a number of material terms were not resolved, the parties had narrowed the issues considerably.

On March 6, 2000, the parties met again with their legal and financial advisors. Counsel for Voyager identified open negotiation matters relating to the proposed transaction. Mr. Peterson and Mr. Schneider met separately with Mr. Torto to inform him of CoreComm's negotiations to acquire ATX. During the next several days, Voyager's attorneys and financial advisors began conducting due diligence on ATX.

93

On March 7, 2000, the board of directors of CoreComm held a preliminary meeting at which Messrs. Knapp and Peterson and Richard J. Lubasch, CoreComm's general counsel, made a presentation to the CoreComm board of the principal terms of the proposed agreements with Voyager as well as ATX. CoreComm's board of directors gave approval to continue negotiations with each party.

On March 9, 2000, the CoreComm board of directors held another meeting at which Messrs. Knapp, Peterson and Lubasch again discussed the principal terms of the proposed merger with Voyager. At this meeting, Goldman Sachs delivered a presentation to the CoreComm board of directors regarding its analysis of the financial terms of the proposed transaction with Voyager. At the conclusion of the presentation, Goldman Sachs expressed its willingness to render an opinion as to the fairness to CoreComm of the consideration to be paid to Voyager under the proposed Voyager merger agreement, subject to negotiation of a definitive merger agreement with terms and in a form not materially different to the form presented at the meeting. After discussion, the CoreComm board unanimously determined that the proposed Voyager merger agreement, the Voyager merger and the issuance of common shares of CoreComm in connection with the Voyager merger were advisable and in the best interests of the CoreComm stockholders, and the CoreComm board approved the Voyager merger agreement and the related issuance of the common shares of CoreComm. The CoreComm board also unanimously resolved to recommend that CoreComm's shareholders approve the issuance of the common shares of CoreComm under the Voyager merger agreement.

On the morning of March 10, 2000, CoreComm and ATX issued a joint press release publicly announcing CoreComm's agreement to buy ATX for approximately $900.0 million in cash and stock.

On March 10, 2000, the parties reconvened in New York and continued discussions to finalize the terms of the proposed merger.

On March 10, 2000, Messrs. Peterson and Schneider met with Mr. Torto and a representative of Morgan Stanley to discuss further any open issues. Following this discussion, Messrs. Torto, Friedly and Hayes, met with Messrs. Knapp, Peterson and Schneider to discuss CoreComm's strategic direction and plans for growth. Following such discussions, Mr. Torto continued the negotiation of the terms of the proposed transaction with Mr. Knapp. At this time, the parties finalized the economic terms of the transaction and agreed on an exchange ratio of 0.292 CoreComm common shares for each Voyager share, $3.00 in cash consideration per Voyager share, and the terms of the collar mechanisms.

On March 10, 2000, CoreComm and Voyager extended the exclusivity period until Monday, March 13, 2000 at 12:00 noon.

From March 10, 2000 through March 12, 2000, definitive agreements to implement the Voyager merger were finalized by the parties.

On March 12, 2000, prior to the execution of the definitive merger agreement, Goldman Sachs delivered its oral opinion to CoreComm management, which was

94

subsequently confirmed by a written opinion, dated March 12, 2000 and addressed to the CoreComm board, that as of that date, the stock consideration and the cash consideration, in the aggregate, to be exchanged by CoreComm under the merger agreement was fair from a financial point of view to CoreComm.

On the evening of March 12, 2000, the Voyager board of directors met by telephone to discuss the proposed merger and the definitive documentation. Legal counsel for Voyager summarized the status of negotiations and terms of the definitive documentation for the Voyager board. Morgan Stanley made a financial presentation to the Voyager board and delivered its opinion that the merger consideration to be received by the holders of shares of common stock of Voyager under the Voyager merger agreement was fair from a financial point of view to Voyager's stockholders. After extensive discussions with its legal counsel and its financial advisors of the risks and advantages of the proposed transaction to Voyager and its stockholders, the Voyager board unanimously approved the proposed Voyager merger, the Voyager merger agreement and the transactions contemplated by it on the terms discussed at the meeting and authorized management to complete and execute the definitive Voyager merger agreement.

On the morning of March 13, 2000, CoreComm and Voyager issued a joint press release publicly announcing the Voyager merger and the execution of the Voyager merger agreement.

RECOMMENDATION OF THE BOARD OF DIRECTORS OF CORECOMM; REASONS FOR THE MERGER

The board of directors of CoreComm has determined that the Voyager merger is in the best interests of CoreComm and its shareholders and has unanimously approved and adopted the Voyager merger agreement. ACCORDINGLY, CORECOMM'S BOARD OF DIRECTORS RECOMMENDS THAT THE SHAREHOLDERS OF CORECOMM VOTE "FOR" APPROVAL AND ADOPTION OF THE VOYAGER MERGER AGREEMENT.

In reaching the determination that the Voyager merger agreement and the Voyager merger are in the best interests of CoreComm and its shareholders, the CoreComm board consulted with CoreComm's management, as well as its financial advisor, legal counsel and accountants and considered the short-term and long-term interests of CoreComm and the other acquisitions available to CoreComm. While the CoreComm board considered all of these factors, it did not make determinations with respect to each of the factors. Rather, the CoreComm board made its judgment with respect to the Voyager merger and Voyager merger agreement based on the total mix of information available to it, and the judgments of individual board members may have been influenced to a greater or lesser degree by their individual views with respect to different factors.

Positive Factors Considered by the CoreComm Board of Directors. In making its determination with respect to the Voyager merger, the CoreComm board considered the following material positive factors:

Geographic Fit and Concentration. Voyager operates principally in Michigan, Ohio, Wisconsin, Illinois and Indiana, and this coverage complements CoreComm's

95

geographic footprint in this region. In addition, because Voyager's subscribers are geographically concentrated, CoreComm will have the ability to offer telephone service to Voyager's subscribers.

Enhanced Position as an Integrated Communications Provider. The Voyager merger will improve CoreComm's ability to market DSL services and enlarge its subscriber base, which will enhance CoreComm's overall growth potential. In addition, post-merger CoreComm will be able to cross-sell its services to both Voyager and CoreComm customers, which will provide an excellent opportunity for post-merger CoreComm to generate additional value per subscriber. The aggregation of the customer base of CoreComm and Voyager will also create a much larger Internet service provider that will be better able to compete with other Internet service providers.

Voyager is a Unique Internet Service Provider Asset. Voyager is a large independent Internet communications company focused on the Midwestern United States. Voyager also has a large installed customer base and a substantial network infrastructure. Voyager has also focused attention on customer care and has been able to achieve good customer retention and word-of-mouth referrals.

Complementary Business Strategies. Voyager and CoreComm have complementary business models and services that will allow CoreComm to offer a broader range of the two companies combined services to both existing and new customers. Both companies have maintained a customer focus, and their businesses rely on their ability to retain and attract customers. Voyager's Internet service provider customers fit within CoreComm's plan of marketing telephone services to Internet service provider customers.

Strong Balance Sheet. Following the Voyager merger, post-merger CoreComm is expected to have a strong balance sheet. The pro forma equity of the two companies combined at December 31, 1999 is approximately $575 million. In addition, post-merger CoreComm should have access to a broad range of financing, including secured and unsecured debt due to increased physical assets.

Management Team. The Voyager merger will give CoreComm access to an experienced management team that has the breadth and depth to effectively lead and manage post-merger CoreComm's targeted growth in the Internet service provider business, make future acquisitions and develop post-merger CoreComm's "Internet-centric" plan.

Opinion of Goldman, Sachs & Co. Goldman, Sachs & Co. has delivered its written opinion, dated March 12, 2000, to the board of directors of CoreComm that, as of that date, the cash consideration and the stock consideration, in the aggregate, to be exchanged under the Voyager merger agreement was fair from a financial point of view to CoreComm. The opinion of Goldman Sachs does not constitute a recommendation as to how any holder of CoreComm common shares should vote with respect to the transaction. A copy of Goldman Sachs' written opinion is attached to this joint proxy statement and prospectus as Annex F, and the

96

shareholders of CoreComm are encouraged to, and should read this opinion in its entirety. Please also see the section of this joint proxy statement and prospectus entitled "The Merger between CoreComm and Voyager -- The Opinion of Goldman Sachs" for more detailed information regarding Goldman Sachs' opinion.

Negative Factors Considered by the CoreComm Board of Directors. The CoreComm board considered the matters described in this joint proxy statement and prospectus under the heading "Risk Factors" as well as the following potentially negative factors in its deliberations concerning the Voyager merger.

Unrealized Benefits. There is a risk that the potential benefits of the Voyager merger may not be realized.

Loss of Key Management. There is a risk of management and employee disruption associated with the Voyager merger, including the risk that despite the efforts of post-merger CoreComm following the Voyager merger, key technical, sales and management personnel might not remain employed by post-merger CoreComm following the Voyager merger.

Service Disruptions. Any disruptions in Voyager's services due to the Voyager merger or system failure could result in the loss of existing and prospective customers, which is one of the key factors on which Voyager's future success is dependent.

Market Changes. There is potential for the dial-up Internet service provider services to become increasingly commoditized, as more Internet service providers start offering dial-up service at lower prices.

Price Pressures. There is a possibility that the increased competition could lead Internet-service providers to change pricing structures, which could negatively affect Voyager's business and financial results.

The CoreComm board concluded that potentially negative factors considered by it were not sufficient, either individually or collectively, to outweigh the advantages of the Voyager merger.

RECOMMENDATION OF THE BOARD OF DIRECTORS OF VOYAGER; REASONS FOR THE MERGER

The board of directors of Voyager has determined that the terms of the Voyager merger, the Voyager merger agreement and the transactions contemplated by the Voyager merger agreement are fair to, and are in the best interests of, Voyager and its stockholders. Voyager's board of directors has unanimously approved the Voyager merger and the Voyager merger agreement. ACCORDINGLY, VOYAGER'S BOARD OF DIRECTORS RECOMMENDS THAT THE STOCKHOLDERS OF VOYAGER VOTE "FOR" APPROVAL AND ADOPTION OF THE VOYAGER MERGER AND THE VOYAGER MERGER AGREEMENT.

In reaching the determination that the Voyager merger and the Voyager merger agreement are in the best interests of Voyager and its stockholders, the Voyager board of directors consulted with Voyager management, legal counsel and accountants and was advised by Morgan Stanley Dean Witter, its financial advisor in this transaction, and

97

considered the short-term and long-term interests of Voyager. In particular, the Voyager board of directors considered the following material factors, among others, all of which it deemed favorable, in reaching its decision to approve the Voyager merger and the Voyager merger agreement:

- Value of Consideration to be Received by Voyager Stockholders in the Voyager Merger as Compared to Historical and Recent Market Price of Voyager Common Stock; Cash Consideration. Based upon the exchange ratio and the closing price of CoreComm common shares on March 10, 2000 (the last trading day prior to the public announcement of the Voyager merger), Voyager stockholders would receive, subject to adjustment, post-merger CoreComm common shares and cash in the Voyager merger having an aggregate value of $17.00, representing a 31% premium over the closing price of $13.00 for Voyager common stock on March 10, 2000 and a 15% premium over $15.00, the price for Voyager common stock at the time of its initial public offering. Additionally, the Voyager board of directors viewed as favorable the meaningful cash component of the Voyager merger consideration of $3.00 per share to be received by Voyager stockholders.

- Adjustment to Exchange Ratio. As a result of the Voyager merger, each share of Voyager common stock held by a Voyager stockholder at the effective time will be exchanged for 0.292 of a post-merger CoreComm common share and $3.00 in cash. If the average trading price of common shares of CoreComm during a specified period ending shortly before the completion of the Voyager merger is at or below $56.97 and at or above $41.17, for each share of Voyager common stock, Voyager stockholders will receive 0.292 of a share of post-merger CoreComm common stock having a value, based on the average trading price, ranging from $12.02 per share to $16.64 per share. For more information about this "collar" provision, please read the section of this joint proxy statement and prospectus entitled "The Merger Agreements -- The Merger Agreement between CoreComm and Voyager -- Merger Consideration."

- Termination Rights of Voyager in the Event of a Decrease in the Price of CoreComm Common Stock. Voyager has the right to terminate the Voyager merger agreement and "walk away" from the Voyager merger if the volume weighted average closing price per share of the CoreComm common shares described above decreases below $33.03, subject to CoreComm's option to "top-up" or increase the number of post-merger CoreComm common shares to be issued to Voyager stockholders so that the aggregate value of each post-merger CoreComm common share to be received by Voyager stockholders will be equal to at least $12.02.

- Voyager's Business, Condition and Prospects. The Voyager board of directors recognized that the market for Internet service providers was becoming increasingly competitive and that the industry, which had been highly fragmented, was experiencing significant consolidation. The Voyager board of directors considered Voyager's plan to remain competitive in the rapidly evolving Internet communications industry through the roll-out of its strategy to become a leading

98

provider of broadband DSL services in the Midwest. In order to roll-out its DSL plan, Voyager would need greater access to capital and expansion of its senior and mid-level management. By merging with CoreComm, the Voyager board of directors believed Voyager would enjoy significantly greater access to such resources and particularly noted CoreComm's strong management team.

- Structure and Tax-Free Nature of the Voyager Merger. The Voyager board of directors viewed as favorable to its determination the fact that a significant portion of the merger consideration to be received by Voyager stockholders would be stock rather than cash. This allows the Voyager stockholders both to share in any future appreciation of post-merger CoreComm and to convert their shares of Voyager common stock into post-merger CoreComm common shares on a tax-free basis, although Voyager stockholders will be taxed on the lesser of cash received or gain realized.

- Termination Rights of Voyager in the Event of a Superior Acquisition Proposal and Termination Fee. The Voyager merger agreement permits the Voyager board of directors to continue to receive unsolicited inquiries and proposals regarding other potential business combinations, negotiate and give information to third parties, and subject to the satisfaction of certain conditions, in the exercise of its fiduciary duties, withdraw or modify its recommendation to the Voyager stockholders regarding the Voyager merger and enter into an agreement with respect to a more favorable transaction with a third party, subject to the payment of a $19.0 million termination fee to CoreComm.

- Increased Market Capitalization. As of March 10, 2000, on a pro forma combined basis, assuming completion of the merger with Voyager and the merger with ATX, the total market capitalization of the surviving company, based on shares of common stock outstanding, would be approximately $2.9 billion, which is considerably greater than the total market capitalization of Voyager of approximately $411.0 million on this date. Based in part on discussions with its financial advisors, the Voyager board of directors believes that this increased total market capitalization will provide Voyager stockholders with enhanced liquidity.

- Morgan Stanley Fairness Opinion. The board of directors of Voyager considered as favorable to its determination the opinion, analyses and presentations of Morgan Stanley to the effect, that as of the date of the opinion, and based upon and subject to certain matters stated in the opinion, the merger consideration to be received by the Voyager stockholders was fair from a financial point of view to the stockholders. The opinion of Morgan Stanley contains a description of the factors considered, the assumptions made and the scope of review undertaken by Morgan Stanley in rendering its opinion. A more detailed description of Morgan Stanley's fairness opinion is provided below under the caption "The Opinion of Morgan Stanley" and the full text of the opinion received by the Voyager board of directors is attached as Annex E.

99

The Voyager board of directors also considered the following potentially negative factors in its deliberations concerning the Voyager merger:

- Limited Public Trading History. CoreComm was spun-off on September 2, 1998, and consequently, the CoreComm common shares have a limited trading history in the public market. The Voyager board of directors, however, did note that the value of a CoreComm common share had increased 372% from its closing price on the first day after the spin-off to its closing price on March 10, 2000, the last trading day prior to the public announcement of the Voyager merger.

- Limited Public Float. Despite CoreComm's larger total market capitalization, the average trading volume of its common shares since the September 2, 1998 spin-off is 150,806 as contrasted with the average trading volume of Voyager since its initial public offering on July 21, 1999, excluding the trading volume on July 21, 1999, of 398,276. The Voyager board of directors believes that an increased public float will result following the completion of the Voyager merger, as well as the ATX merger, thus increasing liquidity for Voyager stockholders.

- Other Potential Transactions May Delay the Completion of the Voyager Merger. The Voyager board of directors noted potential transactions by CoreComm, including the ATX merger, prior to or simultaneously with the completion of the Voyager merger, and the difficulty of evaluating the Voyager merger in light of these potential transactions. The Voyager board of directors also considered the possibility that the closing for the Voyager merger could be delayed until October 31, 2000 or later as a result of these transactions. This negative factor was partially offset by providing for automatic adjustments to the exchange ratio to allow Voyager stockholders to participate in a greater portion of any increases in the trading price of CoreComm common shares in the event that the Voyager merger is not consummated on or prior to July 15, 2000.

- Post-Merger CoreComm Will Have Substantial Indebtedness. The Voyager board of directors considered the substantial indebtedness that post-merger CoreComm will have after completion of the Voyager merger and ATX merger.

- Successful Implementation of CoreComm Business Strategy May Not be Realized. The Voyager board of directors considered the risk that CoreComm is in the early growth stage of its development, having been formed in September, 1998 from previously owned subsidiaries of another company as well as from other independent businesses. As a result, CoreComm has only recently begun to develop the necessary staff to effectively manage and operate its businesses and implement its "Smart LEC" strategy.

- Successful Integration of Acquisitions May Not be Realized. Post-merger CoreComm's success in the telecommunications industry depends largely on its ability to successfully integrate the businesses that it has acquired in the recent past, as well as its ability to integrate the business of Voyager and ATX following the mergers.

100

- Anticipated Benefits May Not be Realized. The Voyager board of directors considered the risk that the anticipated benefits of the Voyager merger to Voyager's stockholders may not be realized as a result of possible changes in the Internet services and telecommunications industry in general, the inability to achieve the anticipated reduction in expenses or other potential difficulties in integrating the two companies.

- Significant Costs Involved. The Voyager board of directors considered the significant costs involved in connection with completing the Voyager merger and the ATX merger and the substantial management time and effort required to complete the Voyager merger and the ATX merger.

The Voyager board of directors was aware of the potential benefits to the members of Voyager's management and the Voyager board of directors, discussed below in "Interests of Certain Persons In the Merger -- Voyager Affiliates," including the acceleration of certain options to acquire shares of Voyager common stock; agreements by certain officers and directors to enter into revised promissory notes related to outstanding loans owed to Voyager by those persons; and the provisions granting indemnification and directors' insurance to the directors of Voyager for actions and omissions of such person occurring prior to the effective time of the Voyager merger. The Voyager board of directors determined that these potential benefits were such that they would not affect the ability of the members of the Voyager board of directors to discharge their duties.

In view of the wide variety of factors considered by the Voyager board of directors, the Voyager board of directors did not find it practicable to, and did not, quantify or otherwise attempt to assign relative weights to the specific factors considered. The Voyager board of directors viewed its position and recommendation as being based on the totality of the information presented to and considered by it. After taking into consideration all the factors set forth above, the Voyager board of directors determined that the potential benefits of the proposed Voyager merger outweighed the potential detriments associated with the proposed Voyager merger.

THE OPINION OF GOLDMAN SACHS

Opinion of Goldman Sachs to CoreComm in the Voyager Transaction. Goldman Sachs has delivered its written opinion, dated March 12, 2000, to the board of directors of CoreComm that, as of that date, the stock consideration and the cash consideration, in the aggregate, to be exchanged under the Voyager merger agreement was fair from a financial point of view to CoreComm.

THE FULL TEXT OF THE WRITTEN OPINION OF GOLDMAN SACHS DATED MARCH 12, 2000, WHICH IDENTIFIES ASSUMPTIONS MADE, MATTERS CONSIDERED AND LIMITATIONS ON THE REVIEW UNDERTAKEN IN CONNECTION WITH THE OPINION, IS ATTACHED AS ANNEX F AND IS INCORPORATED BY REFERENCE IN THIS JOINT PROXY STATEMENT AND PROSPECTUS. SHAREHOLDERS OF CORECOMM ARE URGED TO, AND SHOULD, READ THIS OPINION IN ITS ENTIRETY.

101

In connection with its opinion, Goldman Sachs reviewed, among other things:

- the Voyager merger agreement,

- the annual reports to shareholders and annual reports on Form 10-K of CoreComm for the year ended December 31, 1998,

- registration statement on Form S-1 of Voyager relating to the initial public offering of Voyager,

- interim reports to stockholders and Quarterly Reports on Form 10-Q of CoreComm and Voyager,

- other communications from CoreComm and Voyager to their respective stockholders,

- internal financial analyses and forecasts for CoreComm prepared by the management of CoreComm,

- internal financial analyses and forecasts for Voyager prepared by the management of Voyager and approved for use in its analyses by the management of CoreComm, referred to as the Voyager forecasts, and

- estimates of operating synergies projected by the management of CoreComm to result from the Voyager merger, referred to as the Synergies.

Goldman Sachs also held discussions with members of the senior managements of Corecomm and Voyager regarding the past and current business operations, financial condition, and future prospects of their respective companies. In addition, Goldman Sachs:

- reviewed the reported price and trading activity for the CoreComm and Voyager common stock and relied upon the various valuation analyses for CoreComm that it had previously prepared in connection with the ATX merger,

- compared financial and stock market information for CoreComm and Voyager with similar information for selected other companies the securities of which are publicly traded, and

- reviewed the financial terms of recent business combinations and performed such other studies and analyses as it considered appropriate.

Goldman Sachs relied upon the accuracy and completeness of all of the financial and other information reviewed by it and assumed such accuracy and completeness for purposes of rendering its opinion. Goldman Sachs assumed with CoreComm's consent that the Voyager forecasts and synergies had been reasonably prepared and reflected the best currently available estimates and judgments of CoreComm. In addition, Goldman Sachs did not make an independent evaluation or appraisal of the assets and liabilities of CoreComm or Voyager or any of their respective subsidiaries and Goldman Sachs has not been furnished with any such evaluation or appraisal. The opinion of Goldman Sachs was provided for the information and assistance of the board of directors of CoreComm in connection with its consideration of the transaction contemplated by the Voyager

102

merger agreement and this opinion does not constitute a recommendation as to how any holder of CoreComm shares should vote with respect to the transaction.

CoreComm and Voyager did not impose any material limitations on Goldman Sachs in performing its financial analyses and investigations.

The following is a summary of the material financial analyses used by Goldman Sachs in connection with providing its written opinion, dated March 12, 2000, to CoreComm's board of directors.

THE FOLLOWING SUMMARIES OF FINANCIAL ANALYSES INCLUDE INFORMATION PRESENTED IN TABULAR FORMAT. YOU SHOULD READ THESE TABLES TOGETHER WITH THE TEXT OF EACH SUMMARY.

Historical Stock Trading Analysis. Goldman Sachs reviewed the historical trading performance of the CoreComm and Voyager common stock and a composite index comprised of certain publicly traded Internet service providers and the S&P 500 for the period from March 3, 1999 to March 3, 2000. The Internet service provider composite index consisted of America Online, Inc., EarthLink Network, Inc., Flashnet Communications, Inc., Internet America, Inc., Juno Online Services, Inc., NetZero, Inc. and OneMain.com, Inc. These companies were chosen because they are publicly-traded companies with operations that for purposes of analysis may be considered similar to Voyager. These analyses indicated that the CoreComm common stock outperformed Voyager, the Internet service provider composite and the S&P 500, while Voyager underperformed CoreComm, generally outperformed the Internet service provider composite and generally underperformed the S&P 500 during the period of time analyzed.

Selected Companies Analysis. Goldman Sachs reviewed and compared certain financial information relating to CoreComm and Voyager to corresponding financial information, ratios and public market multiples for the following publicly traded corporations in the Internet service provider industry:

- America Online, Inc.

- EarthLink Network, Inc.

- Flashnet Communications, Inc.

- Internet America, Inc.

- Juno Online Services, Inc.

- NetZero, Inc.

- OneMain.com, Inc.

The selected companies were chosen because they are publicly traded companies with operations that for purposes of analysis may be considered similar to Voyager.

Goldman Sachs also calculated and compared various financial multiples and ratios based on information it obtained from SEC filings, Goldman Sachs Equity Research estimates, other equity research estimates and other publicly available data. The multiples and ratios for CoreComm and Voyager were calculated using their respective

103

common stock closing prices on March 7, 2000. The multiples and ratios for CoreComm and Voyager were based on information provided by their respective management and publicly available data. The multiples and ratios for each of the selected comparable Internet service providers were based on the most recent publicly available information. Goldman Sachs' analyses of the selected companies compared the following to the results for CoreComm and Voyager:

- levered market capitalization as a multiple of estimated 2000 revenue,

- levered market capitalization as a multiple of estimated 2001 EBITDA,

- levered market capitalization as a multiple of estimated 1999 subscribers, and

- levered market capitalization as a multiple of estimated 2000 subscribers.

The results of these analyses are summarized as follows:

Discounted Cash Flow Analysis. Goldman Sachs performed a discounted cash flow analysis of Voyager on a standalone basis, as well as considering the estimated potential benefits of the combination of Voyager and CoreComm, based upon forecasts provided by Voyager management and approved for use in connection with the opinion by the management of CoreComm. Goldman Sachs calculated a range of per share values for the common stock based on the sum of (i) the discounted present value of the five-year (2000-2004) stream of projected after-tax cash flows of Voyager, using discount rates ranging from 14% to 18%; and (ii) the present value of Voyager of the terminal value of Voyager in 2004, assuming an EBITDA exit multiple range between 8.0x and 12.0x. The above financial sensitivity analysis yielded per share values as of January 1, 2000 ranging from $15.19 to $25.20 on a stand alone basis, and $32.97 to $56.77 when considering the estimated potential benefits of the Voyager merger.

Goldman Sachs also examined the sensitivity of the discounted cash flow value of Voyager to changes in operating assumptions. Using for illustration purposes a weighted average cost of capital, or WACC, discount rate of 15% and an EBITDA exit multiple of 11.0x, Goldman Sachs calculated the per share value of Voyager common stock, on

104

both a stand alone basis and considering the estimated potential benefits of the combination, assuming the increase or decrease in revenues and basis change in EBITDA margin. The results of these analyses are as follows:

Pro Forma Merger Analysis. Goldman Sachs prepared pro forma analyses of the financial impact of the merger using discounted cash flows estimates for the five year period of 2000-2004 for CoreComm and Voyager prepared by their respective managements. For each of the years 2000 through 2004, Goldman Sachs assumed merger consideration to be comprised of 81% stock and 19% cash and a share price of $17.00 per share of Voyager common stock. Based on such analyses, the proposed transaction would be highly accretive to CoreComm stockholders on an earnings per share basis in the years 2000 through 2004, considering the estimated potential benefits of the combination and slightly dilutive to CoreComm shareholders on an earnings per share basis in the years 2000 through 2004, on a stand alone basis.

Pro Forma Contribution Analysis. Goldman Sachs reviewed selected estimated future operating and financial information for CoreComm, Voyager and the combined company on a stand alone basis resulting from the merger based on their respective managements' financial forecasts. Goldman Sachs also analyzed the relative income statement contribution of CoreComm and Voyager to the combined company, before taking into account any of the possible benefits that may be realized following the Voyager merger, based upon estimated results for the years 1999 through 2004.

The preparation of a fairness opinion is a complex process and is not necessarily susceptible to partial analysis or summary description. Selecting portions of the analyses or of the summary set forth above, without considering the analyses as a whole, could create an incomplete view of the processes underlying Goldman Sachs' opinion. In arriving at its fairness determination, Goldman Sachs considered the results of all such analyses. No company or transaction used in the above analyses as a comparison is directly comparable to CoreComm or Voyager, or the contemplated transaction.

The analyses were prepared solely for purposes of Goldman Sachs' providing its opinion to the CoreComm board of directors as to the fairness from a financial point of view to CoreComm of the cash consideration and the stock consideration, in the aggregate, to be exchanged under the Voyager merger agreement. These analyses do not purport to be appraisals or necessarily reflect the prices at which businesses or securities actually may be sold. Analyses based upon forecasts of future results are not necessarily indicative of actual future results, which may be significantly more or less favorable than suggested by such analyses. Because these analyses are inherently subject to uncertainty, being based upon numerous factors or events beyond the control of the parties or their respective advisors, none of CoreComm, Voyager, Goldman Sachs or any other person assumes responsibility if future results are materially different from those forecast.

As described above, Goldman Sachs' opinion to the board of directors of CoreComm was one of many factors taken into consideration by the CoreComm board of directors in making its determination to approve the merger agreement. The foregoing is a summary of the material financial analyses used by Goldman Sachs in connection with providing its opinion but it does not purport to be a complete description of the analyses performed by Goldman Sachs.

Goldman Sachs, as part of its investment banking business, is continually engaged in the valuation of businesses and their securities in connection with mergers and

106

acquisitions, negotiated underwritings, competitive biddings, secondary distributions of listed and unlisted securities, private placements, and valuations for estate, corporate and other purposes. Goldman Sachs is familiar with CoreComm having provided investment banking services in conjunction with the acquisition of ATX and having been retained to undertake a study to render their opinion in connection with the transactions contemplated by the Voyager merger agreement.

Goldman Sachs provides a full range of financial, advisory and brokerage services and in the course of its normal trading activities may from time to time effect transactions and hold positions in the securities or options on securities of CoreComm for its own account and for the account of customers.

Under a letter agreement dated February 9, 2000, CoreComm exclusively engaged Goldman Sachs to undertake a study to render an opinion as to the fairness to CoreComm of the possible acquisition of all or a portion of the stock or assets of Voyager. Under the terms of this engagement letter, CoreComm has agreed to pay Goldman Sachs a fee of $2,000,000 in cash for its services upon consummation of such acquisition.

CoreComm also has agreed to reimburse Goldman Sachs for its reasonable out-of-pocket expenses, including attorneys' fees, and to indemnify Goldman Sachs against certain liabilities, including certain liabilities under the federal securities laws.

THE OPINION OF MORGAN STANLEY

Under a letter agreement dated as of December 21, 1999, Morgan Stanley was engaged to provide financial advisory services to Voyager. Morgan Stanley was selected by the Voyager board to act as its financial advisor for the Voyager merger based on Morgan Stanley's qualifications, expertise and reputation, as well as its knowledge of the business and affairs of Voyager. On March 12, 2000, Morgan Stanley delivered its oral opinion to the Voyager board that, as of this date, the consideration to be received by the holders of shares of common stock under the Voyager merger agreement was fair from a financial point of view to the Voyager stockholders. Morgan Stanley later confirmed its oral opinion in writing by delivery of its written opinion dated March 12, 2000, which stated the considerations and assumptions upon which Morgan Stanley's opinion was based.

THE FULL TEXT OF THE OPINION DATED MARCH 12, 2000, WHICH SETS FORTH ASSUMPTIONS MADE, PROCEDURES FOLLOWED, MATTERS CONSIDERED AND LIMITATIONS ON THE SCOPE OF THE REVIEW UNDERTAKEN BY MORGAN STANLEY IN RENDERING ITS OPINION, IS ATTACHED AS ANNEX E TO THIS JOINT PROXY STATEMENT AND PROSPECTUS. VOYAGER STOCKHOLDERS ARE URGED TO READ THE ENTIRE OPINION CAREFULLY. MORGAN STANLEY'S WRITTEN OPINION IS DIRECTED TO THE VOYAGER BOARD AND ONLY ADDRESSES THE FAIRNESS OF THE CONSIDERATION TO BE RECEIVED BY THE HOLDERS OF SHARES OF VOYAGER COMMON STOCK UNDER THE VOYAGER MERGER AGREEMENT FROM A FINANCIAL POINT OF VIEW AS OF THE DATE OF THE OPINION. MORGAN STANLEY'S WRITTEN OPINION DOES NOT ADDRESS ANY OTHER ASPECT OF THE VOYAGER MERGER AND DOES NOT CONSTITUTE A RECOMMENDATION TO ANY VOYAGER STOCKHOLDER AS TO HOW TO VOTE AT THE

107

VOYAGER SPECIAL MEETING. THIS SUMMARY OF THE OPINION IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE OPINION'S FULL TEXT.

In arriving at Morgan Stanley's written opinion, Morgan Stanley, among other things:

- reviewed publicly available financial statements and other information of Voyager and CoreComm;

- reviewed internal financial statements and other financial and operating data concerning Voyager, CoreComm, and ATX prepared by the managements of Voyager, CoreComm, and ATX, respectively;

- reviewed financial projections prepared by the managements of Voyager, CoreComm, and ATX, respectively;

- discussed the past and current operations and financial condition and the prospects of Voyager, including information relating to the strategic, financial and operational benefits anticipated from the Voyager merger with senior executives of Voyager;

- discussed the past and current operations and financial condition and the prospects of CoreComm, including information relating to the strategic, financial and operational benefits anticipated from the Voyager merger and the ATX merger, with senior executives of CoreComm;

- discussed the past and current operations and financial condition and the prospects of ATX, including information relating to the strategic, financial and operational benefits anticipated from the ATX merger, with senior executives of ATX and CoreComm;

- reviewed the pro forma impact of the Voyager merger and the ATX merger on CoreComm's consolidated capitalization and financial ratios;

- reviewed the reported prices and trading activity for the Voyager common stock and the CoreComm common shares;

- compared the financial performance of Voyager, CoreComm, and ATX and the prices and trading activity of the Voyager common stock and the CoreComm common shares with those of other comparable publicly-traded companies and their securities;

- participated in discussions and negotiations among representatives of Voyager, CoreComm and their legal advisors;

- reviewed the Voyager merger agreement, the ATX merger agreement and related documents; and

- performed other analyses and considered other factors that Morgan Stanley considered to be appropriate.

In rendering its opinion, Morgan Stanley assumed and relied upon without independent verification the accuracy and completeness of the information reviewed by

108

Morgan Stanley for the purposes of its opinion. Morgan Stanley relied upon the assessment of the managements of Voyager, CoreComm, and ATX of their ability to retain key employees of their respective companies. With respect to the financial projections, including information relating to certain strategic, financial and operational benefits anticipated from the Voyager merger and the ATX merger, Morgan Stanley assumed they were reasonably prepared on bases reflecting the best currently available estimates and judgments of the future financial performance of Voyager, CoreComm, and ATX. In addition, Morgan Stanley assumed the Voyager merger will be completed in accordance with the terms set forth in the Voyager merger agreement, including that the Voyager merger will be treated as a tax-free reorganization and/or exchange pursuant to the Internal Revenue Code of 1986. Morgan Stanley has not made any independent valuation or appraisal of the assets or liabilities of Voyager, CoreComm, or ATX, nor was Morgan Stanley furnished with any such appraisals. Morgan Stanley's opinion is necessarily based on financial, economic, market and other conditions as in effect on, and the information made available to it as of, the date of this document.

The following is a brief summary of the material financial analyses performed by Morgan Stanley in connection with its oral opinion and the preparation of its opinion letter dated March 12, 2000. Certain of these summaries of financial analyses include information presented in tabular format. In order to fully understand the financial analyses used by Morgan Stanley, the tables must be read together with the text of each summary. The tables alone do not constitute a complete description of the financial analyses.

Historical Public Market Trading Value. Morgan Stanley reviewed the recent stock price performance of Voyager based on an analysis of the historical closing prices and trading volumes from July 21, 1999, the date of Voyager's initial public offering, through March 10, 2000. The following table lists the average daily closing prices of shares of Voyager common stock for the periods indicated. Morgan Stanley then compared the CoreComm offer price of approximately $17.00, based on the closing price of the CoreComm common shares on March 10, 2000, to the average Voyager closing prices over this period.

Comparative Stock Price Performance. As part of its analysis, Morgan Stanley compared the stock price performance of the Voyager common stock from July 21, 1999 through March 10, 2000 with that of the Nasdaq Composite Index and a group of

109

selected domestic Internet service providers and the stock price performance of the CoreComm common shares from March 10, 1999 through March 10, 2000 with that of the Nasdaq Composite Index and a group of selected competitive local exchange carriers.

The group of selected domestic Internet service providers forming Voyager's peer group included EarthLink Network, Inc., Prodigy Communications Corporation, OneMain.Com, Inc. and Internet America, Inc. The group of selected competitive local exchange carriers forming CoreComm's peer group included Allegiance Telecom, Inc., Focal Communications Corporation, MGC Communications, Inc. and US LEC Corp.

Comparable Companies Analysis. Using closing market prices on March 10, 2000, Morgan Stanley calculated aggregate value, defined as equity value adjusted for capital structure, to revenue multiples for Voyager for calendar years 2000 and 2001 and subscriber multiples for Voyager at the end of calendar years 1999 through 2001, based on estimates developed by Voyager's management. Morgan Stanley then compared the revenue and subscriber multiples obtained for Voyager with multiples obtained for the Voyager peer group based on publicly available research estimates. Morgan Stanley calculated aggregate value to calendar year 1999 gross property, plant and equipment multiples and aggregate value to revenue multiples for calendar years 1999 and 2000 for CoreComm based on estimates developed by CoreComm's management. Morgan Stanley then compared the gross property, plant and equipment and revenue multiples for CoreComm with multiples obtained for the CoreComm peer group based on publicly available research estimates. In addition, Morgan Stanley calculated aggregate value to calendar year-end 1999 gross property, plant and equipment multiples and aggregate value to revenue multiples for calendar years 1999 and 2000 for ATX, CoreComm's pending merger partner, based on estimates developed by ATX's management. Morgan Stanley then compared the gross property, plant and equipment and revenue multiples for ATX with multiples obtained for a group of selected peer companies based on publicly available research estimates. The group of selected companies forming ATX's peer group included ITC DeltaCom, Inc., Network Plus Corp., CTC Communications

110

Group, Inc., Northeast Optic Network, Inc. and US LEC Corp. This analysis resulted in the following information:

Morgan Stanley noted that CoreComm's offer price based on the closing price of CoreComm common shares on March 10, 2000 represented a multiple of 5.8x Voyager's calendar year 2000 revenue and 3.6x Voyager's calendar year 2001 revenue.

No company used in the peer group comparison is identical to Voyager, CoreComm or ATX. In evaluating the peer group companies, Morgan Stanley made judgments and assumptions with regard to industry performance, general business, economic, market and financial conditions and other matters, many of which are beyond the control of Voyager, CoreComm and ATX, such as the impact of competition on Voyager, CoreComm and ATX and the industry generally, industry growth and the absence of any material adverse change in the financial condition and prospects of Voyager, CoreComm and ATX or the industry or in the financial markets in general. Mathematical analysis, such as determining the average or median, is not in itself a meaningful method of using peer group data.

Securities Research Analysts' Future Price Targets Analysis. Morgan Stanley reviewed the 12-month price targets for the shares of the Voyager common stock as

111

projected by analysts from various financial institutions in recent reports. These targets reflected each analyst's estimate of the future public market trading price of the Voyager common stock at the end of the particular period considered for each estimate. Morgan Stanley then arrived at the present value for these targets using an estimated equity discount rate of 14.8% for the Voyager common stock.

This analysis supported the following mean and median values for the Voyager common stock:

                                                                         PRESENT

                                                              -------    -------
Mean........................................................  $20.25     $18.43
Median......................................................  $20.50     $18.70

Discounted Cash Flow Analysis. Morgan Stanley performed a discounted cash flow analysis, which considers the present value of projected cash flows using discount rates and terminal year EBITDA multiples as indicated below, of Voyager's business. Morgan Stanley analyzed Voyager's business using a forecast for the period beginning January 1, 2000 and ending December 31, 2004, based on estimates developed by Voyager's management. Morgan Stanley estimated Voyager's discounted cash flow value by using a discount rate range of 13.5% to 14.5% and terminal multiples of estimated 2004 EBITDA ranging from 7.0x to 9.0x. This analysis yielded a range of values for the Voyager common stock of approximately $12 per share to $17 per share. CoreComm's offer price of approximately $17, based on the closing price of CoreComm common shares on March 10, 2000, represented a premium to the discounted cash flow values of 0% to 42%.

Morgan Stanley also performed a discounted cash flow analysis of CoreComm's business. Morgan Stanley analyzed CoreComm's business using a forecast for the period beginning January 1, 2000 and ending December 31, 2005, based on estimates developed by CoreComm's management. Morgan Stanley estimated CoreComm's discounted cash flow value by using a discount rate of 17.5% and terminal multiples of estimated 2004 EBITDA ranging from 9.0x to 11.0x. This analysis yielded a range of values for CoreComm common shares of approximately $63 per share to $78 per share. Morgan Stanley noted that the public market trading price for the CoreComm common stock as of March 10, 2000 was $47.88. The discounted cash flow value of the CoreComm common stock represented a premium to the public market trading value of CoreComm common shares of 32% to 63%. In addition, Morgan Stanley performed a discounted cash flow analysis of ATX's business. Morgan Stanley analyzed ATX's business using a forecast for the period beginning January 1, 2000 and ending December 31, 2004, based on estimates developed by ATX's management. Morgan Stanley estimated ATX's discounted cash flow value by using a discount rate of 17.5% and terminal multiples of estimated 2004 EBITDA ranging from 9.0x to 11.0x. This analysis yielded a range of values for ATX of approximately $722 million to $871 million.

Morgan Stanley performed a variety of financial and comparative analyses solely for purposes of providing its opinion to the Voyager board as to the fairness from a financial point of view to the Voyager stockholders of the merger consideration.

The preparation of a fairness opinion is a complex process and is not necessarily susceptible to partial analysis or summary description. In arriving at its opinion, Morgan Stanley considered the results of all of its analyses as a whole and did not attribute any particular weight to any analysis or factor considered by it. Furthermore, selecting any portion of its analyses, without considering all analyses, would create an incomplete view of the process underlying its opinion. In addition, Morgan Stanley may have given various analyses and factors more or less weight than other analyses and factors, and may have considered various assumptions more or less probable than other assumptions, so that the ranges of valuations resulting from any particular analysis described above should not be taken to be Morgan Stanley's view of the actual value of Voyager, CoreComm or ATX.

In performing its analyses, Morgan Stanley made numerous assumptions with respect to industry performance, general business and economic conditions and other matters, many of which are beyond the control of Voyager, CoreComm or ATX. The analyses performed by Morgan Stanley are not necessarily indicative of future results or actual values, which may be significantly more or less favorable than those suggested by such estimates. The analyses performed were prepared solely as part of Morgan Stanley's analysis of the fairness of the merger consideration from a financial point of view to the Voyager stockholders and were conducted in connection with the delivery of its opinion to the Voyager board. The analyses are not intended to be appraisals or to reflect the prices at which Voyager, CoreComm or ATX might actually be sold or the price at which their securities may trade.

The merger consideration was determined through arm's-length negotiations between Voyager and CoreComm and was approved by the Voyager board. Morgan Stanley did not recommend any specific merger consideration to Voyager or that any specific merger consideration constituted the only appropriate merger consideration for the merger. Morgan Stanley's opinion to the Voyager board was one of many factors taken into consideration by the Voyager board in making its determination to approve the Voyager merger. Consequently, the Morgan Stanley analyses described above should not be viewed as determinative of the opinion of the Voyager board with respect to the value of Voyager or whether the Voyager board would have been willing to agree to different merger consideration.

make a market or otherwise effect transactions, for its own account or for the accounts of customers, in the securities of Voyager, CoreComm and ATX.

Under the letter agreement dated as of December 21, 1999, Morgan Stanley has provided advisory services and a financial opinion in connection with the merger and Voyager has agreed to pay a fee of approximately $5.0 million to Morgan Stanley based on the aggregate value of the transaction if the Voyager merger is consummated. In addition, Voyager has also agreed to indemnify Morgan Stanley and its affiliates, their respective directors, officers, agents and employees and each person, if any, controlling Morgan Stanley or any of its affiliates against specified liabilities and expenses, including the fees of its legal counsel and specified liabilities under the federal securities laws, arising out of Morgan Stanley's engagement and the transactions in connection with their engagement.

INTERESTS OF CERTAIN PARTIES IN THE MERGER -- VOYAGER AFFILIATES

Treatment of Options Granted Under Voyager's Stock Option Plan. Voyager's stock option plan provides for acceleration of unvested shares in the event of a change of control of Voyager. Accordingly, unvested options granted under Voyager's stock option plan to officers and directors of Voyager will vest upon completion of the Voyager merger.

Voyager Employment Agreements. CoreComm has agreed to honor all obligations under the terms of the employment agreements to which Voyager or any of its subsidiaries is presently a party.

Registration Rights Agreement. Upon consummation of the Voyager merger, certain principal stockholders of Voyager, including certain officers and directors, will enter into a registration rights agreement pursuant to which these principal stockholders will have the right to demand that post-merger CoreComm, at any time on or after six months from the date of the closing of the Voyager merger, register all or part of their registrable shares of common stock, provided that post-merger CoreComm is not required to effect more than one registration. In addition, these principal stockholders may participate, or "piggy-back" in equity offerings initiated by post-merger CoreComm that are registered under the Securities Act of 1934, subject to, the approval of the underwriters involved with any such equity offering and other customary terms and conditions.

Indemnification and Insurance. Under the Voyager merger agreement, post-merger CoreComm will preserve all rights to indemnification existing as of March 12, 2000 in favor of any current or former director, officer, or employee of Voyager for a period of at least six years following the Voyager merger. Post-merger CoreComm will also indemnify directors, officers, agents and employees of Voyager against liabilities or claims arising before the Voyager merger is completed and as a result of their positions with Voyager. Finally, post-merger CoreComm will pay the applicable person's legal and other expenses in connection with any proceeding arising out of any matter occurring until the Voyager merger is completed.

114

Prior to the effective time of the Voyager merger, CoreComm will purchase, subject to limitations as to cost, an extended reporting period endorsement under Voyager's existing directors' and officers' liability insurance coverage for Voyager's directors and officers which shall provide Voyager's directors and officers with coverage at least as favorable as the current policy for six years following the Voyager merger. It is anticipated that the total aggregate cost of such coverage will be approximately $750,000.

Certain Indebtedness of Voyager Affiliates. In connection with the execution of the Voyager merger agreement, certain executive officers and a director agreed to revise the terms of certain outstanding promissory notes which each such person had issued in favor of Voyager.

- Voyager had previously made two loans, evidenced by promissory notes, to Christopher Torto, its Chief Executive Officer and President. In April 1999, Voyager made a loan in the principal amount of $0.5 million to Mr. Torto which is payable over three years and in July 1999, Voyager made a loan in the principal amount of $5.0 million which is payable over four years. Mr. Torto executed a side agreement with CoreComm in which Mr. Torto agreed to enter into revised notes effective as of the closing of the Voyager merger. In the side letter, Mr. Torto agreed to pay 25% of the principal due on the promissory notes at the closing of the Voyager merger with the remainder of the principal and interest due two years from the closing, subject to certain earlier repayment obligations if Mr. Torto sells any shares of CoreComm common stock prior to the maturity of the revised notes.

- In January 1999, Voyager made a loan to Mr. Friedly, Chairman of the Voyager board of directors, in the principal amount of $4.2 million, in connection with the sale of certain Voyager stock to Mr. Friedly. The promissory note issued in connection with this loan matures in January 2003. Mr. Friedly executed a side agreement with CoreComm in which Mr. Friedly agreed to enter into a revised note effective as of the closing of the Voyager merger. In the side letter, Mr. Friedly agreed to pay 25% of the principal due on the promissory note at the closing of the Voyager merger with the remainder of the principal and interest due two years from the closing, subject to certain earlier repayment obligations if Mr. Friedly sells any shares of CoreComm common stock prior to the maturity of the revised note.

- In January 1999, Voyager made a loan to Mr. Osvaldo deFaria, the Chief Operating Officer of Voyager, in the principal amount of $1.8 million, in connection with the sale of certain Voyager stock to Mr. deFaria. The promissory note issued in connection with this loan matures in January 2003. Mr. deFaria executed a side agreement with CoreComm in which Mr. deFaria agreed to enter into a revised note effective as of the closing pursuant to which Mr. deFaria agreed to certain earlier repayment obligations if Mr. deFaria sells any shares of CoreComm common stock prior to the maturity of the revised note.

ACCOUNTING TREATMENT

APPRAISAL RIGHTS

Under Delaware law, a Voyager stockholder may exercise his, her or its appraisal rights by delivering to Voyager a demand in writing for the appraisal of its shares and not voting for or consenting in writing to the Voyager merger agreement or the Voyager merger. Voyager stockholders considering seeking appraisal should recognize that the fair value of shares could be determined to be more than, the same as or less than the value of the Voyager merger consideration to which stockholders are entitled if they do not exercise their appraisal rights. Stockholders who elect to exercise appraisal rights must comply strictly with all of the procedures set forth in Section 262 of the Delaware General Corporation Law to preserve those rights. We have attached a copy of Section 262 of the Delaware General Corporation Law, which sets forth these appraisal rights, as Annex D to this joint proxy statement and prospectus.

Section 262 of the Delaware General Corporation Law sets forth the required procedure a stockholder seeking appraisal must follow. Making sure that you actually perfect your appraisal rights can be complicated. The procedural rules are specific and must be followed completely. Failure to comply with the procedure may cause you to lose your appraisal rights. The following is only a summary of your rights and the procedure relating to appraisal rights and is qualified in its entirety by the provisions of Section 262 of the Delaware General Corporation Law. Please review Section 262 for the complete procedure. Voyager will not give you any notice other than as described in this joint proxy statement and prospectus and as required by Delaware law.

APPRAISAL RIGHTS PROCEDURES

If you are a Voyager stockholder and you wish to exercise your appraisal rights, you must satisfy the following provisions of Section 262 of the Delaware General Corporation Law. Only a record holder may demand appraisal, and therefor, if you are the beneficial owner of shares held of record by a broker, bank or other nominee, you must direct such record owner to comply with the requirements of the statute.

- You must make a written demand for appraisal: You must deliver a written demand for appraisal to Voyager before the taking of the vote on the Voyager merger agreement and the Voyager merger at the special meeting.

- You must not vote for or consent in writing to the Voyager merger: You must not consent to or vote for the Voyager merger or the adoption of the Voyager merger agreement. If you vote for or consent by written consent to the Voyager merger agreement and Voyager merger, you will not be entitled to any right to seek appraisal.

116

- You must continuously hold your Voyager shares: You must continuously hold, as a record holder, your shares of Voyager common stock from the date you make the demand for appraisal through the completion of the Voyager merger. If you are the record holder of Voyager common stock on the date you make a written demand for appraisal but then transfer your shares before the Voyager merger, you will lose any right to appraisal in respect of those shares.

- You should read the paragraphs below for more details on making a demand for appraisal.

A written demand for appraisal of Voyager common stock must be executed by or on behalf of a stockholder of record and must reasonably identify the stockholder and that he, she or it intends to demand appraisal of his, her or its shares. If you own Voyager common stock in a fiduciary capacity, such as a trustee, guardian or custodian, the demand for appraisal must be executed by or for the record owner.

If you own Voyager common stock with one or more persons, such as in a joint tenancy or tenancy in common, the demand for appraisal must be executed by or for all joint owners. An authorized agent, which could include one or more of the joint owners, may sign the demand for appraisal for a stockholder of record; however, the agent must expressly disclose who the stockholder of record is and that the agent is signing the demand as that stockholder's agent.

If you are a record owner, such as a broker, who holds Voyager common stock as a nominee for others, you may exercise a right of appraisal with respect to the shares held for one or more beneficial owners, while not exercising such right for other beneficial owners. In such a case, you should specify in the written demand the number of shares as to which you wish to demand appraisal. If you do not expressly specify the number of shares, we will assume that your written demand covers all the shares of Voyager common stock that are in your name.

If you are a Voyager stockholder who elects to exercise appraisal rights, you should mail or deliver by hand a written demand to:

Voyager.net, Inc.
4660 S. Hagadorn Road, Suite 320 East Lansing, MI 48823
Attention: Secretary

It is important that Voyager receives all written demands before the stockholder meeting on September , 2000. As explained above, this written demand should be signed by, or on behalf of, the stockholder of record. The written demand for appraisal should specify the stockholder's name and mailing address, the number of shares of common stock owned, and that the stockholder is thereby demanding appraisal of his, her or its shares.

If you fail to comply with any of these conditions and the Voyager merger becomes effective, you will only be entitled to receive the Voyager merger consideration provided in the Voyager merger agreement.

117

Written Notice. Within 10 days after the completion of the Voyager merger, Voyager must give written notice setting forth the date the Voyager merger has become effective to each stockholder who has fully exercised his, her or its appraisal rights in full compliance with the conditions of Section 262 of the Delaware General Corporation Law.

Petition with the Chancery Court. Within 120 days after the completion of the Voyager merger, either Voyager or any stockholder who has complied with the conditions of Section 262 may file a petition for appraisal in the Delaware Chancery Court demanding that the Chancery Court determine the value of the shares of Voyager stock held by all of the stockholders who are entitled to appraisal rights. Voyager has no present intention of filing an appraisal petition. Accordingly, if you intend to preserve your rights of appraisal, you should file a petition in the Delaware Court of Chancery. Because Voyager has no obligation to file a petition, if no stockholder files a petition within 120 days after the completion of the Voyager merger, you will lose your rights of appraisal.

Withdrawal of Demand. If you change your mind and decide you no longer want to assert appraisal rights, you may withdraw your demand for appraisal rights at any time within 60 days after the closing of the Voyager merger. You may also withdraw your demand for appraisal rights after 60 days after the closing of the Voyager merger, but only with the written consent of Voyager. Once a petition for appraisal has been filed with the Delaware Court of Chancery, such proceeding may not be discussed as to any stockholder without approval of the court. If you effectively withdraw your demand for appraisal rights, you will receive the merger consideration provided in the Voyager merger agreement.

Request for Appraisal Rights Statement. If you have complied with the conditions of Section 262, you are entitled to receive a statement from Voyager which sets forth the number of shares held by stockholders who have demanded appraisal rights, and the number of stockholders who own those shares. To receive this statement, you must send a written request to Voyager within 120 days after the completion of the Voyager merger. Voyager has 10 days after receiving a request to mail you the statement.

Chancery Court Procedures. If you properly file a petition for appraisal in the Delaware Chancery Court, Voyager will then have 20 days after service of a copy of the petition is made on it to provide the Chancery Court with a list of the names and addresses of all stockholders who have demanded appraisal rights and have not reached an agreement with Voyager as to the value of their shares. At a hearing on the petition, the Chancery Court will determine which stockholders, if any, have fully complied with Section 262 of the Delaware General Corporation Law and whether they are entitled to appraisal rights under
Section 262. The Chancery Court may also require you to submit your stock certificates to the Register in Chancery so that it can note on the certificates that an appraisal proceeding is pending. If you do not follow the Chancery Court's directions, you may be dismissed from the proceeding.

Appraisal of Shares. After the Chancery Court determines which stockholders are entitled to appraisal rights, it shall determine the fair value of your shares exclusive of

118

any value arising from the expectation or accomplishment of the Voyager merger. After the Chancery Court determines the fair value of their shares, it will direct Voyager to pay that value to the stockholders who qualified to have their shares appraised. The Chancery Court can also direct Voyager to pay interest, simple or compound, on that value if the Chancery Court determines that interest is appropriate. In order to receive your payment for your shares, you must then surrender your stock certificates to Voyager.

The Chancery Court could determine that the fair value of shares of stock is more than, the same as or less than the merger consideration. You should also be aware that an opinion of an investment banking firm that the Voyager merger is fair is not an opinion of an investment banking firm that the merger consideration constitutes fair value under Section 262.

Costs and Expenses of Appraisal Proceeding. The costs of the appraisal proceeding may be assessed against Voyager and/or the stockholders participating in the appraisal proceeding, as the Chancery Court deems equitable under the circumstances. You may also request that the Chancery Court allocate the expenses of the appraisal action incurred by any stockholder pro rata against the value of all of the shares entitled to appraisal.

Loss of Stockholder's Rights. If you demand appraisal rights, after the completion of the Voyager merger you will not be entitled to:

- vote shares of stock, for any purpose, for which you have demanded appraisal rights;

- receive payment of dividends or any other distribution with respect to such shares, except for dividends or distributions, if any, that are payable to holders of record as of a record date prior to the effective time of the Voyager merger; or

- receive the payment of the consideration provided for in the Voyager merger agreement, unless you properly withdraw your demand for appraisal.

If you fail to comply strictly with the procedures described above you will lose your appraisal rights. Consequently, if you wish to exercise your appraisal rights, we strongly urge you to consult a legal advisor.

THE MERGER BETWEEN CORECOMM AND ATX

BACKGROUND OF THE MERGER BETWEEN CORECOMM AND ATX

On December 9, 1999, Michael Peterson of CoreComm was contacted by Louis Friedman, a Managing Director at Donaldson, Lufkin & Jenrette Securities Corporation. Mr. Friedman informed Mr. Peterson that DLJ had been engaged by ATX to assist it in considering various strategic alternatives, including a possible sale of ATX, and inquired whether CoreComm would be interested in receiving a confidential information memorandum prepared by DLJ concerning ATX with a view towards participating in a transaction with ATX. Mr. Peterson indicated that CoreComm would be interested in receiving the confidential information memorandum.

On December 15, 1999, CoreComm executed a confidentiality agreement and was given a copy of the confidential information memorandum. The confidential information memorandum provided a detailed summary of ATX's corporate structure, business and projections and was intended to solicit interest in a business combination transaction. CoreComm was informed by DLJ that various other interested parties selected by DLJ had also received a copy of the confidential information memorandum and that following a review of such materials, all interested parties would be requested to submit a nonbinding indication of interest, which should include, among other things, the form of a proposed transaction, the form of consideration and a valuation range for ATX. CoreComm was informed that based on these nonbinding indications of interest, parties selected by DLJ and ATX would be invited to participate in a second phase which would include management presentations, tours of facilities, access to a data room and other due diligence procedures. DLJ informed CoreComm that the deadline for receipt of indications of interest was 12:00 noon on January 7, 2000.

Over the next three weeks, members of CoreComm management reviewed the materials that had been supplied. During this same period, representatives of CoreComm also spoke to representatives of DLJ in order to obtain certain clarifications and supplemental information.

On December 28, 1999, Goldman, Sachs & Co. was engaged by CoreComm to act as its financial advisor and to undertake a study to enable it to render an opinion in connection with the possible acquisition of all or a portion of the equity interest or assets of ATX.

On January 7, 2000, Michael Peterson met with Thomas Gravina, who was at that time Co-Chief Executive Officer of ATX and James Broner of DLJ to discuss in more detail the business and operations of ATX and CoreComm. Later that same day, CoreComm submitted a formal indication of interest. At that time, the proposal contemplated the purchase of substantially all the stock or assets of ATX by way of purchase or merger and assumed an estimation of valuation of ATX between $700.0 million and $900.0 million. The indication of interest further stated that any transaction would be subject to valuation adjustments depending on:

- ATX's debt and other noncurrent liabilities;

120

- working capital adjustments; and

- capital expenditures amounts.

At a regularly scheduled meeting of the CoreComm board of directors held on January 18, 2000, the CoreComm board of directors reviewed for the first time in a preliminary fashion the potential transaction with ATX. At that time the board of directors authorized CoreComm to continue to review a potential transaction with ATX.

On January 19, 2000, the management of ATX conducted a presentation for representatives of CoreComm's senior management at ATX's executive offices in Bala Cynwyd, Pennsylvania, a suburb of Philadelphia. Attending on behalf of CoreComm were Patty Flynt, Chief Operating Officer, Mr. Peterson and other representatives of CoreComm. In addition, CoreComm was accompanied by representatives of Goldman Sachs. All of ATX's senior management, including Mr. Gravina and Debra Buruchian, the other Co-Chief Executive Officer at that time, Tim Allen, Vice President of Sales and Marketing, and Jeffrey Coursen, Vice President of Strategic Development, were present, as were representatives of DLJ.

On January 24 and January 25, 2000, counsel to CoreComm conducted legal due diligence in a data room at ATX's headquarters in Bala Cynwyd, Pennsylvania. In addition, Goldman Sachs also conducted its financial due diligence. On those dates CoreComm simultaneously conducted operational due diligence at the same location.

On February 1, 2000, a meeting was held at ATX's headquarters in Bala Cynwyd, Pennsylvania. This meeting was attended by Barclay Knapp, the President, Chief Executive Officer and Chief Financial Officer of CoreComm, Mr. Peterson, Mr. Gravina, Michael Karp (ATX's then principal partner and current principal stockholder) and a representative of DLJ. The purpose for these discussions was for the parties to further familiarize themselves with each other and to further assess the interest of the parties in pursuing a business combination transaction.

On February 3, 2000, DLJ informed CoreComm that it was invited to submit a definitive proposal to ATX as part of the process DLJ was conducting on behalf of ATX. CoreComm was informed that all definitive proposals had to be received by Tuesday, February 22, 2000. The invitation was accompanied by a draft merger agreement prepared by ATX's outside counsel. CoreComm was asked to mark up the agreement, provide clear descriptions of its contemplated structure for the transaction, clearly state the valuation and the form of consideration in a transaction, as well as provide other customary terms to be included in a proposal.

Between February 3, 2000 and February 22, 2000, on a number of occasions representatives of CoreComm met and/or had discussions with representatives of ATX, DLJ and Goldman Sachs in order for both parties to obtain additional information about each other (including information that CoreComm desired to have in order to prepare its definitive proposal) and for both parties to conduct operational due diligence.

On February 22, 2000, CoreComm submitted its proposal to DLJ and ATX. That proposal contemplated a structure substantially in the form being submitted for approval

121

in this joint proxy statement and prospectus. The proposal assumed an estimated valuation of ATX at approximately $800.0 million, with valuation adjustments depending on:

- debt and other noncurrent liabilities;

- working capital adjustments; and

- capital expenditure amounts.

The proposal contemplated the $800.0 million being allocated $80.0 million in cash, $200.0 million in common stock and $520.0 million in preferred stock.

On February 23, 2000, DLJ invited CoreComm and its legal and financial advisers to meet with representatives of ATX and its financial and legal advisers in order to discuss and resolve outstanding due diligence items. On February 25, 2000, a meeting was held in the offices of ATX's lawyers.

During the next week, ATX and CoreComm and their respective advisors conducted intensive due diligence on the remaining legal and financial issues and negotiated via conference calls and through the exchange of facsimiles the underlying documentation and various proposals. The negotiations covered, among other things, the determination of the total consideration, as well as the mix among the cash, common stock and convertible preferred stock components.

On March 2, 2000, CoreComm presented a revised proposal to DLJ. The major revisions involved increasing the cash portion of the consideration and adjusting the features of the convertible preferred stock to create more immediate value for the existing ATX stockholders.

On March 3, 2000, the parties entered into an exclusivity agreement that provided that the parties would negotiate exclusively with each other until 9:00
a.m. on Thursday, March 9, 2000.

On March 3, 2000, the parties orally agreed on a term sheet for the transaction laying out the total consideration, the mix between the different components of the consideration, and the general terms of the different components of the consideration.

On March 4, 2000, Mr. Gravina and Mr. Knapp discussed issues related to management roles, incentive plans for management and employees and the future operations of the combined company. This conversation was a continuation of discussions Mr. Gravina had with Mr. Peterson throughout the period of negotiations which continued up until the date of execution of the ATX merger agreement.

Beginning on March 6, 2000, and continuing on March 7, 2000, representatives of the parties met at CoreComm's attorneys' offices in New York City with a view to negotiating definitive terms for the transaction. Negotiations centered primarily around the structure of the transaction and details related to the forms of consideration to be received by the existing ATX stockholders. In addition, at these meetings CoreComm management indicated for the first time to ATX and DLJ the potential transaction being negotiated with Voyager.

122

On March 7, 2000, CoreComm's board of directors held a special meeting at which they received a report from Messrs. Peterson and Lubasch as to the status of the transaction (as well as the Voyager merger). The board of directors indicated its approval to continue negotiations and finalize documentation for a definitive agreement in each transaction, subject to final approval by the board of directors.

On March 8, 2000, the parties met with their respective lawyers and advisers in order to review the documentation and the parties agreed to have their representatives reconvene in New York on March 9, 2000 in order to finalize the transaction. Also, on March 8, 2000, the parties extended the exclusivity agreement until 4:30 A.M. on Friday, March 10, 2000.

On March 9, 2000, the parties again met at CoreComm's attorneys' offices to finalize documentation and negotiate the remaining open issues.

Also on March 9, 2000, the CoreComm board of directors held a meeting to approve the ATX merger agreement and the ATX merger. Representatives of Goldman Sachs made a presentation regarding its analysis of the financial terms of the proposed transaction and delivered their oral opinion, which was subsequentially confirmed in writing that, as of that date, the stock consideration and the cash consideration, in the aggregate, to be paid by CoreComm under the ATX merger agreement was fair from a financial point of view to CoreComm.

Late on the evening of March 9, 2000, the material open issues having been resolved, documentation was completed and definitive agreements relating to the ATX merger and the other related transactions were executed. The ATX merger was announced publicly early on March 10, 2000.

Beginning in mid-July, CoreComm, ATX and the stockholders of ATX began discussions to explore the possibility of restructuring the terms of the ATX merger to increase the portion of the $150 million of cash consideration that could be paid, at CoreComm's option, in the form of notes, and to make other changes to the terms of the consideration to be received by the ATX stockholders. Negotiations continued through July 31, 2000, when the parties agreed to amend the original ATX merger agreement. The CoreComm board of directors approved all of the amendments.

RECOMMENDATION OF THE BOARD OF DIRECTORS OF CORECOMM; REASONS FOR THE ATX MERGER

The board of directors of CoreComm has determined that the ATX merger is fair and in the best interests of the shareholders of CoreComm and has unanimously approved and adopted the ATX merger agreement. ACCORDINGLY, CORECOMM'S BOARD OF DIRECTORS RECOMMENDS THAT THE SHAREHOLDERS OF CORECOMM VOTE "FOR" APPROVAL AND ADOPTION OF THE ATX MERGER AGREEMENT.

In considering the recommendation of the CoreComm board of directors with respect to the ATX merger, CoreComm shareholders should also consider that some of

123

the members of the CoreComm board of directors have interests in the merger that may be different from, or in addition to, the interests of the shareholders of CoreComm generally. For more information concerning the interests of these persons in the ATX merger, please refer to the section of this joint proxy and prospectus entitled "The Merger between CoreComm and ATX -- Interests of Certain Parties in the Merger -- CoreComm Affiliates."

In reaching the determination that the ATX merger agreement and the ATX merger are in the best interests of CoreComm and its shareholders, CoreComm's board of directors consulted with CoreComm's management, as well as its financial advisor, legal counsel and accountants and considered the short-term and long-term interests of CoreComm and other acquisitions available to CoreComm. The factors considered by CoreComm's board of directors include those described below. While all of these factors were considered by CoreComm's board of directors, CoreComm's board of directors did not make determinations with respect to each of the factors. Rather, CoreComm's board of directors made its judgment with respect to the ATX merger and the ATX merger agreement based on the total mix of information available to it, and the judgments of individual directors may have been influenced to a greater or lesser degree by their individual views with respect to different factors.

In particular, the CoreComm board of directors considered the following material factors, among others, all of which it deemed favorable, in reaching its decision to approve the ATX merger and the ATX merger agreement:

- Judgment, advice and analyses of management. The board of directors placed significant reliance on the judgment, advice and analyses of its management with respect to the strategic, financial and operational benefits of the merger with ATX, based in part on the business, financial, accounting and legal due diligence investigations performed with respect to ATX.

- Potential synergies as a result of the ATX merger. Among other things, the combination of ATX and CoreComm should enable post-merger CoreComm to extract the better sales practices and superior skills that are currently found in their separate sales forces, eliminating those practices and skills that are less effective. Growth is anticipated through the offering of post-merger CoreComm's residential services in the geographic markets currently serviced by ATX, while incorporating ATX's proven customer service and retention capabilities. ATX has a customer base consisting of approximately 100,000 local access lines and approximately 320,000 long distance access line equivalents, an asset which potentially can be penetrated with CoreComm's services. Specifically, combining with ATX should augment CoreComm's penetration of its "Smart LEC" rollout in the Eastern U.S. and provide an immediate boost to the increasing Internet-centric focus of CoreComm's business. Coupled with general cost synergies inherent in combining back-office operations and correlated business strategies, the board of directors recognized the potential for efficiencies and cost savings.

- Superior business strategy, capability, market position and growth prospects. The board of directors believes that a business combination with ATX will enhance

124

CoreComm's goal of expansion and the creation of a national telecommunications presence. ATX's principal markets, Pennsylvania, New Jersey, Delaware, Maryland, the District of Columbia and Virginia, are within the geographic areas that were next scheduled to be developed by CoreComm. In addition, by combining CoreComm's operations in the Midwest with ATX's presence in the Mid-Atlantic, post-merger CoreComm's footprint will expand to areas currently occupied by a number of different regional Bell operating companies and other competitive local exchange carriers. The board of directors believes that the ATX merger would be accretive to post-merger CoreComm EBITDA, thus enhancing its cash flow and enabling additional expansion with available funds. Furthermore, it is expected that post-merger CoreComm will be able to target higher margin data-centric business customers than CoreComm does today. Accordingly, the potential expanded customer base could combine with enhanced revenues per customer (and the reduced churn characteristics ATX brings) to provide more rapid growth.

- The ATX merger agreement. The express terms and conditions of the ATX merger agreement provide an equitable basis to combine the two companies from the standpoint of CoreComm. The form of consideration given to ATX stockholders potentially was a particularly attractive feature in that a significant portion of the consideration was non-cash, in the form of post-merger CoreComm common and preferred stock and, potentially, senior notes.

- Advantages of a larger enterprise. The combination of ATX and CoreComm should result in a larger company that should provide post-merger CoreComm with more depth to the management team and cost savings in its dealings with its vendors, due to the larger volume of business it would generate for them.

- Improved cash flow. Historically, ATX has generated substantial revenues. If those results were to continue, post-merger CoreComm could manifest better financial results, capital raising abilities and available cash than CoreComm alone.

- The complementary nature of CoreComm's and ATX's businesses. In addition to the synergies discussed above, the board of directors also focused on the complementary features of ATX's and CoreComm's businesses. For instance, ATX employs "Smart Build" network architecture similar to that utilized by CoreComm.

- Opinion of CoreComm's financial advisor. Goldman, Sachs & Co. has delivered its written opinion, dated March 9, 2000, to the board of directors of CoreComm that, as of that date, the stock consideration and the cash consideration, in the aggregate, to be paid by CoreComm under the ATX merger agreement, as in effect on that date, was fair from a financial point of view to CoreComm. The opinion of Goldman Sachs does not constitute a recommendation as to how any holder of CoreComm common shares should vote with respect to the transaction. The board of directors of CoreComm also reviewed the methodologies used by Goldman Sachs in rendering this opinion in valuing ATX. A copy of Goldman Sachs' written opinion dated August 10, 2000 is attached to this joint proxy statement and prospectus as Annex G, and the shareholders of CoreComm are

125

encouraged to, and should read this opinion in its entirety. Please also see the section of this joint proxy statement and the prospectus entitled, "The Merger between CoreComm and ATX -- The Opinion of Goldman Sachs" for more detailed information regarding Goldman Sachs' opinion.

The CoreComm board of directors also considered the following potentially negative factors in its deliberations concerning the merger:

- ATX is a private entity. The fact that ATX is a newly-formed corporation derived from two limited partnerships meant that analyzing its financial information, especially in light of absence of historical financial information prepared in accordance with United States generally accepted accounting principles, was more difficult than if ATX had been a publicly-traded entity. In addition, ATX's management infrastructure is not as well-developed as that of a publicly-traded company.

- Inherent challenges to effecting the transaction. The inherent challenges to effecting the ATX merger and the attendant risk that management resources may be diverted from other strategic opportunities and from operational matters for an extended period of time.

- The possibility that, despite the efforts of the combined company, technical and management personnel might not remain employees with post-merger CoreComm. There is a risk of management and employee disruption with the ATX merger, including the risk that despite the efforts of post-merger CoreComm following the ATX merger, key technical, sales and management personnel might not remain employed by post-merger CoreComm.

The board of directors of CoreComm concluded that the potential negative factors considered by it were not sufficient, either individually or collectively, to outweigh the advantages of the ATX merger.

THE OPINION OF GOLDMAN SACHS

Opinion of Goldman Sachs to CoreComm in the ATX Transaction. Goldman Sachs has delivered its written opinions, dated March 9, 2000 and August 10, 2000 to the board of directors of CoreComm that, as of these dates, the stock consideration and the cash consideration in the aggregate, to be paid by CoreComm under the March 9, 2000 ATX merger agreement and that agreement, as amended through July 31, 2000, respectively, was fair from a financial point of view to CoreComm.

THE FULL TEXT OF THE WRITTEN OPINION OF GOLDMAN SACHS DATED AUGUST 10, 2000, WHICH IDENTIFIES ASSUMPTIONS MADE, MATTERS CONSIDERED AND LIMITATIONS ON THE REVIEW UNDERTAKEN IN CONNECTION WITH THE OPINION, IS ATTACHED AS ANNEX G AND IS INCORPORATED HEREIN BY REFERENCE IN THIS JOINT PROXY STATEMENT AND PROSPECTUS. SHAREHOLDERS OF CORECOMM ARE URGED TO, AND SHOULD, READ THIS OPINION IN ITS ENTIRETY.

126

In connection with its August 10, 2000 opinion, Goldman Sachs reviewed, among other things:

- the ATX merger agreement, as amended through July 31, 2000,

- the annual reports to shareholders and annual reports on Form 10-K of CoreComm for the year ended December 31, 1999,

- audited cash basis financial statements of ATX for the two years ended December 31, 1997,

- draft GAAP basis financial statements of ATX for the three years ended December 31, 1999,

- interim reports to shareholders and Quarterly Reports on Form 10-Q of CoreComm,

- other communications from CoreComm to their shareholders,

- other information related to ATX,

- internal financial analyses and forecasts for CoreComm and ATX prepared by their respective managements, and

- internal financial analyses and forecasts for ATX prepared by the management of ATX and approved for use in its analyses by the management of CoreComm, which is referred to as the ATX forecasts.

Goldman Sachs also held discussions with members of the senior managements of CoreComm and ATX regarding the past and current business operations, financial condition, and future prospects of their respective companies. In addition, Goldman Sachs:

- reviewed the reported price and trading activity for the CoreComm common stock and performed various valuation analyses of CoreComm based upon projections by the management of CoreComm and other financial and stock market information,

- compared certain financial and stock market information for CoreComm and ATX with similar information for certain other companies the securities of which are publicly traded, and

- reviewed the financial terms of certain recent business combinations and performed such other studies and analyses as it considered appropriate.

Goldman Sachs relied upon the accuracy and completeness of all of the financial and other information reviewed by it and assumed such accuracy and completeness for purposes of rendering its opinion. Goldman Sachs assumed with CoreComm's consent that the ATX forecasts had been reasonably prepared and reflected the best currently available estimates and judgments of ATX. In addition, Goldman Sachs did not make an independent evaluation or appraisal of the assets and liabilities of CoreComm or ATX or any of their respective subsidiaries and Goldman Sachs has not been furnished with any such evaluation or appraisal. The opinion of Goldman Sachs was provided for the information and assistance of the board of directors of CoreComm in connection with its

127

consideration of the transaction contemplated by the ATX merger agreement and this opinion does not constitute a recommendation as to how any holder of CoreComm shares should vote with respect to such transaction.

CoreComm and ATX did not impose any material limitations on Goldman Sachs in performing its financial analyses and investigations.

The following is a summary of the material financial analyses used by Goldman Sachs in connection with providing its opinion to CoreComm's board of directors on March 9, 2000.

In connection with its August 10, 2000 opinion, Goldman Sachs updated certain of the analyses described below and the results of such updates did not change Goldman Sachs' opinion as to the fairness, from a financial point of view, of the stock consideration and the cash consideration, in the aggregate, to be paid by CoreComm under the ATX merger agreement. The updated Goldman Sachs discounted cash flow analysis of ATX on a standalone basis used the same methodology described below under "Discounted Cash Flow Analysis" below but used a range of discount rates of 15% to 35% and a range of EBITDA exit multiples of 9x to 12x yielded values as of June 30, 2000 ranging from $464,000,000 to $1,161,000,000.

THE FOLLOWING SUMMARIES OF FINANCIAL ANALYSES INCLUDE INFORMATION PRESENTED IN TABULAR FORMAT. YOU SHOULD READ THESE TABLES TOGETHER WITH THE TEXT OF EACH SUMMARY.

Historical Stock Trading Analysis. Goldman Sachs reviewed the historical trading performance of the CoreComm common stock and three composite indices comprised of certain publicly traded competitive local exchange carriers for the period from May 1, 1999 to March 1, 2000. The first composite index consisted of Allegiance Telecom, Focal, Mpower Communications and US LEC, or "Smart Build Competitive Local Exchange Carriers." The second composite index consisted of CTC, e.spire and ITC DeltaCom, or "Other competitive local exchange carriers." The third composite index was Network Plus, Inc. These companies were chosen because they are publicly-traded companies with operations that for purposes of analysis may be considered similar to ATX Telecommunications Services, Inc.

Selected Companies Analysis. Goldman Sachs reviewed and compared certain financial information relating to CoreComm and ATX to corresponding financial information, ratios and public market multiples for the following publicly traded corporations in the competitive local exchange carrier industry:

SMART BUILD COMPETITIVE LOCAL     OTHER COMPETITIVE LOCAL      COMPETITIVE LOCAL
      EXCHANGE CARRIERS              EXCHANGE CARRIERS         EXCHANGE CARRIERS

Focal Communications Corp.      e.spire Communications Inc.
Mpower Communications Inc.           ITC DeltaCom Inc.
       US LEC Corp.

128

The selected companies were chosen because they are publicly traded companies with operations that for purposes of analysis may be considered similar to CoreComm and ATX.

Goldman Sachs also calculated and compared various financial multiples and ratios based on information it obtained from SEC filings, Goldman Sachs Equity Research estimates, other equity research estimates and other publicly available data. The multiples and ratios for CoreComm were calculated using the CoreComm common stock closing price on March 7, 2000. The multiples and ratios for CoreComm were based on information provided by its management. The multiples and ratios for each of the selected comparable competitive local exchange carriers were based on the most recent publicly available information. Goldman Sachs' analyses of the selected companies compared the following to the results for CoreComm:

- levered market capitalization, which is the market value of fully diluted common equity plus the book value of debt and capital lease obligations less cash, as a multiple of gross plant, property and equipment (PPE),

- levered market capitalization as a multiple of net PPE,

- levered market capitalization as a multiple of estimated 2000 revenue,

- levered market capitalization as a multiple of estimated 2001 revenue, and

- levered market capitalization as a multiple of estimated 2002 earnings before interest, taxes, depreciation and amortization, or EBITDA.

The results of these analyses are summarized as follows:

Discounted Cash Flow Analysis. Goldman Sachs performed a discounted cash flow analysis of ATX Telecommunications Services, Inc. on a standalone basis based upon forecasts provided by ATX management and approved for use in connection with the

129

opinion by the management of CoreComm. Goldman Sachs calculated a range of values for the common stock based on the sum of (i) the discounted present value of the five-year (2000-2004) stream of projected after-tax cash flows of ATX, using a range of weighted average cost of capital, or WACC, discount rates between 14% and 17%; and (ii) the present value of ATX of the terminal value of ATX Telecommunications Services, Inc. in 2004, assuming an EBITDA exit multiple range between 9.0x and 12.0x. The above financial sensitivity analysis yielded values as of January 1, 2000 ranging from $759,000,000 to $1,121,000,000.

Goldman Sachs also examined the sensitivity of the discounted cash flow value of ATX to changes in operating assumptions. Using for illustration purposes a WACC discount rate of 15% and an EBITDA exit multiple of 11.0x, Goldman Sachs calculated the value of ATX assuming the increase or decrease of up to 20% in the variations of number of new consultants and their respective productivities. Finally, using the same illustrative scenario, Goldman Sachs analyzed the value of ATX assuming increases in capital expenditures and attrition, which is the number of local lines and their associated revenues terminated in a given year. The results of these analyses are as follows:

Pro Forma Merger Analysis. Goldman Sachs prepared pro forma analyses of the financial impact of the ATX merger using discounted cash flows estimates for the five year period of 2000 through 2004 for CoreComm and ATX prepared by their respective managements. For each of the years 2000 through 2004, Goldman Sachs assumed the consideration to be paid to ATX stockholders comprised of 56% stock, 28% convertible

131

stock and 17% cash and a ten day weighted average share price of $45.10 per share of CoreComm common stock, a 10% premium to the closing price of CoreComm common stock on March 7, 2000. Based on these analyses, the proposed transaction would be slightly dilutive to CoreComm's stockholders on a 2004 discounted cash flow basis.

Pro Forma Contribution Analysis. Goldman Sachs reviewed selected estimated future operating and financial information for CoreComm, ATX and the combined company resulting from the merger based on their respective managements' financial forecasts. Goldman Sachs also analyzed the relative income statement contribution of CoreComm and ATX to the combined company based upon estimated results for the years 1999 through 2004.

The preparation of a fairness opinion is a complex process and is not necessarily susceptible to partial analysis or summary description. Selecting portions of the analyses or of the summary set forth above, without considering the analyses as a whole, could create an incomplete view of the processes underlying Goldman Sachs' opinions. In arriving at its fairness determination, Goldman Sachs considered the results of all of these analyses. No company or transaction used in the above analyses as a comparison is directly comparable to CoreComm or ATX or the contemplated transaction.

The analyses were prepared solely for purposes of Goldman Sachs' providing its opinions to the CoreComm board of directors as to the fairness from a financial point of view to CoreComm of the stock consideration and the cash consideration, in the aggregate, to be paid by CoreComm under the ATX merger agreement. These analyses do not purport to be appraisals or necessarily reflect the prices at which businesses or securities actually may be sold. Analyses based upon forecasts of future results are not necessarily indicative of actual future results, which may be significantly more or less favorable than suggested by such analyses. Because these analyses are inherently subject to uncertainty, being based upon numerous factors or events beyond the control of the parties or their respective advisors, none of CoreComm, ATX, Goldman Sachs or any other person assumes responsibility if future results are materially different from those forecast.

As described above, Goldman Sachs' March 9, 2000 opinion to the board of directors of CoreComm was one of many factors taken into consideration by the CoreComm board of directors in making its determination to approve the ATX merger agreement. The foregoing is a summary of the material financial analyses used by Goldman Sachs in connection with providing its opinions but it does not purport to be a complete description of the analyses performed by Goldman Sachs.

Goldman Sachs, as part of its investment banking business, is continually engaged in the valuation of businesses and their securities in connection with mergers and acquisitions, negotiated underwritings, competitive biddings, secondary distributions of listed and unlisted securities, private placements, and valuations for estate, corporate and other purposes. Goldman Sachs has acted as CoreComm's financial advisor in connection with, and has participated in negotiations leading to, the ATX merger agreement.

132

Goldman Sachs may also provide investment banking services to CoreComm in the future. CoreComm selected Goldman Sachs as its financial advisor because it is a nationally recognized investment banking firm that has substantial experience in transactions similar to the ATX merger.

Goldman Sachs provides a full range of financial, advisory and brokerage services and in the course of its normal trading activities may from time to time effect transactions and hold positions in the securities or options on securities of CoreComm for its own account and for the account of customers.

Under a letter agreement dated December 28, 1999, CoreComm exclusively engaged Goldman Sachs to act as its financial advisor and to undertake a study to enable it to render an opinion in connection with the possible acquisition of all or a portion of the equity interests or assets of ATX. Under the terms of this engagement letter, CoreComm has agreed to pay Goldman Sachs a transaction fee based on the outcome of the transaction as follows:

- if at least 50% of the outstanding equity interests or assets (based on the book value thereof) of ATX is acquired in one or more transactions, Goldman Sachs will be paid a transaction fee of $7,000,000; and

- if less than 50% of the outstanding equity interests or assets (based on the book value thereof) of ATX is acquired, Goldman Sachs will be paid a mutually acceptable transaction fee.

CoreComm has agreed to pay the transaction fee to Goldman Sachs in cash upon consummation of such acquisition.

CoreComm also has agreed to reimburse Goldman Sachs for its reasonable out-of-pocket expenses, including attorneys' fees, and to indemnify Goldman Sachs against certain liabilities, including certain liabilities under the federal securities laws.

INTERESTS OF CERTAIN PARTIES IN THE MERGER -- CORECOMM AFFILIATES

Merger Agreement Terms Governing the Composition of the Board of Directors of Post-merger CoreComm. The ATX merger agreement provides that the board of directors of CoreComm will become the members of the board of directors of post- merger CoreComm after the ATX merger and that the current directors of ATX will resign. For more information regarding the directors of post-merger CoreComm, please read the section of this joint proxy statement and prospectus entitled "Management of Post-merger CoreComm."

Merger Agreement Terms Governing the Composition of Post-merger CoreComm's Management. The ATX merger agreement provides that the current officers of CoreComm will become the officers of post-merger CoreComm after the ATX merger and that the current officers of ATX will resign. For more information regarding the officers of post-merger CoreComm, please read the section of this joint proxy statement and prospectus entitled "Management of post-merger CoreComm."

133

Accelerated Vesting of CoreComm Stock Options. All outstanding options under CoreComm's 1998 and 1999 stock option plans will vest and become exercisable upon the completion of the ATX merger. CoreComm has obtained waivers from its directors and officers and is seeking waivers from its other employees to forego the accelerated vesting of these options.

ACCOUNTING TREATMENT

For more information regarding the accounting treatment of the ATX merger, please refer to the unaudited pro forma financial data of ATX in the section of this joint proxy statement and prospectus entitled "Unaudited Pro Forma Financial Data."

APPRAISAL RIGHTS

CoreComm shareholders have no appraisal rights with respect to the ATX merger. CoreComm shareholders will have appraisal rights with respect to the domestication merger. Please read the section of this discussion of the merger transactions entitled "-- The Domestication Merger -- Appraisal Rights" for more information regarding appraisal rights with respect to the domestication merger.

THE DOMESTICATION MERGER

PRINCIPAL REASONS FOR THE DOMESTICATION PROPOSAL

The CoreComm board of directors has determined that the domestication merger is fair and in the best interests of CoreComm and its shareholders and has unanimously approved the domestication merger. The domestication merger will not occur unless either the Voyager merger or the ATX merger or both mergers are to be completed immediately after the completion of the domestication merger.
ACCORDINGLY, CORECOMM'S BOARD OF DIRECTORS RECOMMENDS THAT THE SHAREHOLDERS OF CORECOMM VOTE "FOR" AUTHORIZATION OF THE DOMESTICATION MERGER SO LONG AS EITHER THE VOYAGER MERGER OR THE ATX MERGER OR BOTH MERGERS WILL BE COMPLETED IMMEDIATELY AFTER THE COMPLETION OF THE DOMESTICATION MERGER.

The domestication merger is motivated principally by the tax efficiencies that the board of directors of CoreComm believes will be achieved if CoreComm changes its domicile from Bermuda to the State of Delaware in the United States immediately prior to completing either the ATX merger or the Voyager merger.

If the Voyager merger occurs but the ATX merger does not occur, and if CoreComm does not change its domicile immediately prior to the Voyager merger, the Voyager merger would not be able to be structured as a tax-free transaction. This would effectively have prevented Voyager from entering into the transaction.

If only the ATX merger occurs or if both the ATX merger and the Voyager merger occur, the board of directors of CoreComm believes it is also in the best interests of

134

CoreComm and its shareholders to change CoreComm's domicile to the United States in order to avoid the tax inefficiencies that would result if CoreComm were to remain a Bermuda corporation in which case it would become a subsidiary of a Delaware parent (post-merger CoreComm). Specifically, as a Bermuda company, it would not be able to consolidate for United States federal income tax purposes with post-merger CoreComm. Moreover, if CoreComm remained a Bermuda corporation after it became a wholly-owned subsidiary of post-merger CoreComm, CoreComm would become subject to the "deemed dividend" and other provisions applicable to "controlled foreign corporations" under the "subpart F" rules of the United States federal income tax code of 1986, as amended, which were enacted in order to discourage U.S. companies from conducting certain operations through foreign subsidiaries.

APPRAISAL RIGHTS

If you are a shareholder of CoreComm who does not vote in favor of the domestication merger and are not satisfied that you have been offered the fair value of your common shares, you may (within one month after the date notice of the CoreComm Special General Meeting was given) apply to the Bermuda courts to appraise the fair value of your common shares.

Within one month after the Bermuda court's appraisal, CoreComm will be entitled to pay you an amount equal to the value of your common shares as appraised by the court. However, where the court has appraised any shares under this procedure and the amalgamation has been completed prior to the appraisal then, within one month after the court's appraisal, if the amount paid to you for your shares is less than the appraisal by the court, CoreComm will pay to you the difference between the amount paid to you and the value appraised by the court. There is no appeal from an appraisal by the court under this procedure.

THE INCREASE IN SHARE CAPITAL

CoreComm's board of directors has determined that the increase in share capital of CoreComm to 200 million common shares and 5 million preferred shares is in the best interests of CoreComm and its shareholders and has unanimously approved the increase in share capital. ACCORDINGLY, CORECOMM'S BOARD OF DIRECTORS RECOMMENDS THAT THE SHAREHOLDERS OF CORECOMM VOTE "FOR" THE PROPOSAL TO INCREASE CORECOMM'S SHARE CAPITAL.

The board of directors of CoreComm recommends that shareholders vote for the increase in share capital in order to facilitate future acquisitions by CoreComm in the event the ATX merger and the Voyager merger do not occur. The increase in share capital will not be needed if either the ATX merger or the Voyager merger occurs, because post-merger CoreComm will have authorized share capital of 200 million common shares and 5 million preferred shares.

THE MERGER AGREEMENTS

The following is a brief summary of the significant provisions of the merger agreements. Copies of the merger agreements between CoreComm and Voyager and between CoreComm and ATX are attached to this joint proxy statement and prospectus as Annex A and Annex B, respectively. A copy of the amalgamation agreement between CoreComm and CoreComm Merger Sub, Inc. is attached to this joint proxy statement and prospectus as Annex C. YOU SHOULD READ BOTH MERGER AGREEMENTS AND THE AMALGAMATION AGREEMENT CAREFULLY AND IN THEIR ENTIRETY.

THE MERGER AGREEMENT BETWEEN CORECOMM AND VOYAGER

The following is a brief summary of the significant provisions of the merger agreement between CoreComm and Voyager. A copy of the Voyager merger agreement is attached as Annex A and incorporated into this joint proxy statement and prospectus. YOU SHOULD READ THE VOYAGER MERGER AGREEMENT CAREFULLY AND IN ITS ENTIRETY.

GENERAL

The Voyager merger agreement provides for the merger of a newly-formed wholly-owned subsidiary of CoreComm with and into Voyager. Voyager will survive and become a wholly-owned subsidiary of post-merger CoreComm.

MERGER CONSIDERATION

In the Voyager merger, each outstanding share of common stock, par value $0.0001 per share, of Voyager will be converted into the right to receive $3.00 in cash and 0.292 of a share of common stock of post-merger CoreComm based on an exchange ratio calculated as follows:

If the average trading price prior to closing per common share of CoreComm is:

- equal to or greater than $41.17 and equal to or less than $56.97 (subject to adjustment as described below), the exchange ratio will be fixed at 0.292;

- greater than $56.97, the exchange ratio will be calculated by dividing $16.64 by the average trading price per CoreComm common share; or

- less than $41.17 and equal to or greater than $33.03, the exchange ratio will be calculated by dividing $12.02 by the average trading price per CoreComm common share; or

- less than $33.03, then Voyager has the right to notify CoreComm it wishes to terminate the Voyager merger agreement:

- if Voyager gives that notification, CoreComm can prevent the termination by adjusting the exchange ratio so that the Voyager stockholders receive $12.02 worth of post-merger CoreComm common stock per share of Voyager common stock; and

136

- if Voyager does not give that notification, the exchange ratio will be 0.3639 shares of post-merger CoreComm common stock for each share of Voyager common stock, subject to adjustments described below to preserve the tax-free treatment of the Voyager merger.

The average trading price per CoreComm common share will be computed by taking the volume weighted average trading price of CoreComm common shares for ten randomly selected trading days out of the 20 consecutive trading days ending with the last day prior to the closing of the Voyager merger.

ADJUSTMENTS TO STOCK CONSIDERATION

If the average trading price of CoreComm common shares is below $33.03, Voyager has the right to notify CoreComm that it wishes to terminate the Voyager merger agreement. The average trading price will be calculated as of the end of the trading day prior to the scheduled closing date of the Voyager merger, so it will only be possible to determine whether Voyager has the right to give the termination notification on that date.

-- Voyager elects not to give the termination notice:

Voyager stockholders will be entitled to receive merger consideration with a total value equal to 0.3639 of a share of common stock of post-merger CoreComm, plus $3.00 for each share of Voyager common stock.

In order to ensure that the Voyager merger will be treated as a tax-free reorganization under the federal tax laws, the composition of the consideration will be adjusted to 80% post-merger CoreComm common stock and 20% cash. The value of the post-merger CoreComm common stock for purposes of the adjustment will be based on the trading price of the CoreComm common shares on the date the Voyager merger closes.

The following table shows, for various assumed trading prices of CoreComm common stock on the closing date:

- the total value of the consideration to be received;

- the composition, cash versus stock, of the consideration after the adjustment; and

- the fraction of a share of post-merger CoreComm common stock to be issued for each share of Voyager common stock, after adjustment.

-- Voyager elects to give the termination notice:

- CoreComm may elect to adjust the fraction of a share of post-merger CoreComm common stock to be issued in respect of each share of Voyager common stock so that the value of that fraction of a share will be $12.02. In that case, Voyager may not terminate the Voyager merger agreement.

For example, if the average trading price of CoreComm common shares were $20.00, then Voyager could give CoreComm notice of its intention to terminate the Voyager merger agreement. If CoreComm elects not to accept the termination, it would be required to increase the fraction of a share of post-merger CoreComm common stock to be issued in respect of each share of Voyager common stock to 0.601 of a share. In this example, Voyager stockholders would receive 0.601 of a share of post-merger CoreComm common stock plus $3.00 in cash for each share of Voyager common stock, totaling $15.02 worth of consideration per share.

The following table sets forth the exchange ratios between post-merger CoreComm common stock and Voyager common stock for some average trading prices of CoreComm common shares, assuming that Voyager notifies CoreComm of its intention to terminate the Voyager merger agreement and CoreComm elects to adjust the exchange ratio:

                   $30.00                                             0.401

- CoreComm may also elect not to adjust the exchange ratio, in which case the Voyager merger agreement will terminate and the Voyager merger will not occur.

To date, the Voyager board of directors has not made any decision as to whether Voyager will notify CoreComm that it wishes to terminate the Voyager merger agreement if the average trading price is less than $33.03. To date, the CoreComm board of directors has not made any decision as to whether it would elect to adjust the

138

exchange ratio between Voyager common stock and post-merger CoreComm common stock.

Adjustments will also be required to be made to the exchange ratio if (1) the closing of the Voyager merger has not occurred on or prior to July 15, 2000,
(2) CoreComm has engaged in a transaction that would (x) require the approval of the shareholders of CoreComm, (y) require CoreComm to include information relating to the transaction in the pro forma financial statements that are required to be contained in this joint proxy statement and prospectus or (z) require CoreComm to amend or restate its pro forma financial statements in any material manner, and (3) all other conditions to closing have been satisfied (or waived by the party entitled to waive the condition) or are capable of being satisfied on that date with reasonable best efforts.

In these circumstances, commencing on the later to occur of July 16, 2000 and the first business day after which the circumstances described above are present, which is referred to as the trigger date, the fraction of a share of post-merger CoreComm common stock that a Voyager stockholder will be entitled to receive will be fixed at 0.292 so long as the average trading price per CoreComm common share does not exceed $47.875 multiplied by the applicable collar percentage, which will be increased by an additional five percentage points per each 31 day period beginning on the sixteenth calendar day following the trigger date.

The following chart presents some examples of how the exchange ratio and maximum value of the merger consideration would be adjusted assuming a base stock price of $47.875 and a trigger date of July 16, 2000:

                                             EXCHANGE RATIO TO BE FIXED

CLOSING DATE                 PERCENTAGE      BY THE COLLAR PERCENTAGE)        CONSIDERATION
------------                 ----------      --------------------------      ---------------
July 16....................    121.5%                  $58.17                    $19.99
August 31..................    126.5%                  $60.56                    $20.68
October 1..................    131.5%                  $62.96                    $21.38
November 1.................    136.5%                  $65.35                    $22.08

In addition, the base amount of $47.875 is to be adjusted:

- upon any reclassification, recapitalization, stock split, reverse stock split, combination or exchange of shares or any dividend payable in CoreComm common shares so that the existing Voyager stockholders achieve the same economic effect originally contemplated; and

- upon any distribution to CoreComm shareholders of, or rights or warrants for, capital stock, other than common stock debt, other assets, other than cash dividends or by reducing the base amount in a manner designed to reflect the decrease in value achieved by the distribution.

139

CoreComm may only effect a distribution described in this paragraph, if the distribution does not include operating assets that are required to maintain the current operating businesses of CoreComm, Inc. (a subsidiary of CoreComm) and the distribution of such operating assets would not have a material adverse effect on the current operating businesses of CoreComm, Inc., provided that this paragraph shall not prohibit a distribution of the local multipoint distribution service licenses and related assets.

If the average trading price of CoreComm common shares is above $33.03, the fraction of a share of post-merger CoreComm common stock to be received by Voyager stockholders for each share of Voyager common stock will be adjusted, based on the average trading price. Under that adjustment formula, Voyager stockholders will receive up to a maximum of $16.64 worth of post-merger CoreComm common stock for each share of Voyager common stock plus the $3.00 in cash.

All per-share consideration may be adjusted if CoreComm engages in any transaction that has the mathematical effect of reducing the value of each share of CoreComm common stock while preserving CoreComm's existing shareholder's total value, such as a stock split or spin-off. In that case, the shares of post-merger CoreComm common stock to be received by Voyager's stockholders will be increased to preserve the value to be received.

Post-merger CoreComm will not issue fractional shares in the Voyager merger. As a result, the total number of shares of post-merger CoreComm common stock that each Voyager stockholder receives in the Voyager merger will be rounded down to the nearest whole number. Each of these stockholders will also receive a cash payment for the remaining fractional share.

POST CLOSING CAPITALIZATION

The percentages calculated below do not take into account the exercise of any outstanding stock options or warrants or the conversion of any convertible securities that would result in the issuance of the common equity of any of the companies mentioned.

Assuming that the ATX merger does not occur and that no adjustment to the exchange ratio between Voyager common stock and post-merger CoreComm common stock is made, following the Voyager merger, post-merger CoreComm will have approximately 49.3 million shares of common stock outstanding. Voyager stockholders will own approximately 18.7% of this total. The remaining 81.3% of post-merger CoreComm's common stock will be owned by CoreComm's common stockholders as of immediately prior to the Voyager merger.

Assuming that the ATX merger occurs and that no adjustment to the exchange ratio between Voyager or ATX common stock and post-merger CoreComm common stock is made, following the Voyager merger, post-merger CoreComm will have approximately 61.7 million shares of common stock outstanding. Voyager stockholders will own approximately 15.0% of this total. The remaining 85.0% of post-merger CoreComm's common stock will be owned by a combination of CoreComm's current

140

common shareholders and ATX's common stockholders or their transferees as of immediately prior to the ATX merger.

Assuming that the average trading price of CoreComm common shares is $20.00 and CoreComm elects to adjust the exchange ratio between Voyager common stock and post-merger CoreComm common stock, following the Voyager merger and without taking into account the ATX merger, post-merger CoreComm will have approximately 53.1 million shares of its common stock outstanding. Voyager stockholders will own approximately 24.5% of that total, and the remaining 75.5% will be owned by CoreComm shareholders as of immediately prior to the Voyager merger.

Assuming that the average trading price of CoreComm common shares is $20.00 and CoreComm elects to adjust the exchange ratio between Voyager common stock and post-merger CoreComm common stock, following the ATX merger and the Voyager merger, post-merger CoreComm will have approximately 65.5 million shares of its common stock outstanding. Voyager stockholders will own approximately 19.9% of that total. Current ATX stockholders will own approximately 18.9% of that total, and the remaining 61.2% will be owned by CoreComm shareholders as of immediately prior to the Voyager merger.

The calculations contained in the preceding two paragraphs do not take into account the exercise of any outstanding stock options or warrants or the conversion of any convertible securities that would result in the issuance of the common equity of any of the companies involved.

ADJUSTMENTS TO STOCK AND CASH CONSIDERATION

The amount of cash consideration, which is $3.00 for each share of Voyager common stock, that Voyager stockholders are entitled to receive could be adjusted if either of the tax opinions to be delivered by counsel to CoreComm or Voyager is not reasonably expected to be delivered because less than 80% of the value of the merger consideration would be in the form of post-merger CoreComm common stock. In this case, the number of common shares of post-merger CoreComm to be received will be increased, and accordingly the amount of cash to be received will be reduced, so that the value of the shares of common stock of post-merger CoreComm to be received in the Voyager merger will constitute 80% of the total merger consideration. The purpose of this adjustment is to ensure that the transaction will be treated as a tax-free reorganization under federal tax laws.

EFFECTIVE TIME OF THE VOYAGER MERGER

Promptly after the satisfaction or waiver of the conditions of the Voyager merger set forth in the Voyager merger agreement, CoreComm will file a certificate of merger with the Secretary of State of the State of Delaware. When this filing has been made, a newly-formed subsidiary of CoreComm will be merged with and into Voyager, and the separate corporate existence of this merger subsidiary will cease. Voyager will survive the Voyager merger and exist as a wholly-owned subsidiary of post-merger CoreComm. The directors of Voyager immediately following the Voyager merger will be those of

141

CoreComm's merger subsidiary. Immediately following the Voyager merger, the officers of Voyager immediately prior to the Voyager merger will continue as the officers of Voyager.

VOYAGER STOCK OPTIONS

Each outstanding Voyager stock option will become an option to acquire a number of shares of post-merger CoreComm common stock equal to the number of shares of Voyager common stock subject to the option immediately prior to the effective time using a formula based on the exchange ratio used to determine the fraction of a share of post-merger CoreComm common stock to be received by Voyager stockholders in connection with the Voyager merger plus the quotient obtained by dividing the cash consideration received by Voyager stockholders in connection with the merger by the average trading price of CoreComm common shares. Under the Voyager stock option plan, all outstanding options will vest and become exercisable upon completion of the Voyager merger. The issuance of the shares of post-merger CoreComm common stock to be received upon exercise of the options issued by post-merger CoreComm will be registered by post-merger CoreComm.

EXCHANGE OF CERTIFICATES

Post-merger CoreComm will appoint an exchange agent to handle the exchange of the Voyager common stock certificates in the Voyager merger. Once the Voyager merger is complete, post-merger CoreComm will deposit with the exchange agent the certificates representing post-merger CoreComm common stock, the aggregate cash consideration, including the cash to be provided instead of fractional shares, and any related dividends or distributions, issuable in the merger in exchange for outstanding shares of Voyager common stock.

Soon after the closing of the Voyager merger, the exchange agent will send to each holder of Voyager common stock a letter of transmittal for use in the exchange and instructions explaining how to surrender certificates to the exchange agent. Holders who surrender their certificates to the exchange agent, together with a properly completed letter of transmittal, will receive the appropriate merger consideration. Holders of unexchanged stock certificates will receive any dividends or other distributions payable by post-merger CoreComm after the Voyager merger only after their certificates are surrendered. VOYAGER STOCKHOLDERS SHOULD NOT RETURN STOCK CERTIFICATES WITH THE ENCLOSED PROXY CARD.

No certificates or scrip representing CoreComm common stock will be issued upon surrender for exchange of Voyager certificates. Cash will be issued instead of fractional shares of post-merger CoreComm common stock otherwise issuable upon surrender of those certificates, based on the closing price for CoreComm common shares on Nasdaq on the first business day immediately following the closing of the Voyager merger.

If Voyager stock certificates have been lost, stolen or destroyed, Voyager stockholders will only be entitled to obtain post-merger CoreComm common stock and the cash consideration by providing an affidavit of loss and, if required by post-merger

142

CoreComm, posting a bond in an amount sufficient to protect post-merger CoreComm against claims related to the Voyager certificates.

NO SOLICITATIONS

Voyager has agreed in the Voyager merger agreement that it will not, and will cause its subsidiaries and affiliates and their respective officers, directors, employees, investment bankers, attorneys, accountants and other advisors or representatives not to, solicit, initiate, or encourage (including by way of furnishing non-public information), or take any action to facilitate, any inquiries or the making of any proposal that constitutes an acquisition proposal or any inquiries or making of any proposal that constitutes, or is reasonably expected to lead to, an acquisition proposal or participate in any activities, discussions or negotiations regarding an acquisition proposal. Under the Voyager merger agreement, an acquisition proposal means any proposed or actual:

- merger, consolidation or similar transaction involving Voyager;

- sale or other disposition of any assets representing 15% or more of the consolidated assets of Voyager and its subsidiaries;

- issuance, sale or other disposition of securities representing 15% or more of the votes of the outstanding shares of Voyager common stock;

However, Voyager may furnish information to, and enter into discussions or negotiations with, any person that makes an unsolicited written acquisition proposal if:

- after consultation with its outside legal counsel, the Voyager board determines in good faith that these actions are necessary for the Voyager board to comply with its fiduciary duties to the Voyager stockholders under applicable law;

- the proposal is not subject to financing contingencies or is, in the good faith judgment of the Voyager board after consultation with a nationally recognized financial advisor, reasonably capable of being financed and is at least as likely to be consummated as the Voyager merger;

- the Voyager board determines in good faith that the acquisition proposal would result in a more favorable transaction to Voyager's stockholders from a financial point of view; and

- Voyager enters into a confidentiality agreement with the person making the proposal.

For any acquisition proposal that it receives, Voyager agreed to notify CoreComm of the identity of the company making the proposal and the material terms of the proposal

145

and to provide CoreComm with a copy of any written proposal. Additionally, Voyager agreed to inform CoreComm of, and provide CoreComm with copies of, any material changes to the proposal. Voyager also agreed to terminate and to cause its subsidiaries and affiliates and their respective officers, directors, employees, investment bankers, attorneys, accountants and other advisors, to terminate activities, discussions or negotiations relating to any acquisition proposal that was ongoing at the time of the signing of the Voyager merger agreement.

CONDUCT OF THE BUSINESS

Conduct of Business by Voyager

Voyager has agreed to carry on its business, and cause its subsidiaries to carry on their businesses, in the usual, regular and ordinary course of business, consistent with past practice and in accordance with and to the extent consistent with the business plan of Voyager, with no less diligence and effort than would be applied in the absence of the Voyager merger agreement and will use its reasonable best efforts to preserve intact its and its subsidiaries business organization, to keep available the services of the present officers and key employees and to preserve the goodwill of customers, suppliers and all other persons having business relationships with Voyager. In addition, without the prior written consent of CoreComm, Voyager has agreed that it will not among other things:

- enter into any agreement or arrangement that materially limits Voyager or its subsidiaries or that would, after the closing of the merger, limit or restrict Voyager or CoreComm or their affiliates from engaging or competing in any line of business or in any geographic area, other than in the ordinary course of business consistent with past practice;

- adopt a plan of, or resolutions providing for, complete or partial liquidation, merger, consolidation, restructuring, recapitalization or reorganization;

- settle, release, waive or otherwise compromise any material rights, claims or litigation; or

- take any action that would result in any of Voyager's representations or warranties set forth in the Voyager merger agreement becoming untrue or cause any conditions to closing to not be satisfied, other than those actions that would not materially adversely affect Voyager's ability to complete the transactions contemplated by the Voyager merger agreement.

CONDUCT OF BUSINESS BY CORECOMM

Without the prior written consent of Voyager, CoreComm will not declare, set aside or pay any dividends or make any other distributions, except for dividends paid by a subsidiary of CoreComm to CoreComm or any subsidiary of CoreComm that is, directly

147

or indirectly, wholly-owned by CoreComm and except as permitted by the Voyager merger agreement.

MEETINGS OF STOCKHOLDERS; OBLIGATIONS TO RECOMMEND

Voyager has agreed to take all actions necessary to convene a meeting of its stockholders and to consider and vote upon the approval of the Voyager merger agreement and the Voyager merger and CoreComm has agreed to take all actions necessary to convene a meeting of its shareholders to consider and vote upon the Voyager merger agreement and the issuance of common stock of CoreComm in connection with the Voyager merger.

The Voyager board has agreed to recommend to its stockholders the adoption of the Voyager merger agreement. The Voyager board is not permitted to withdraw or modify its recommendation unless:

- Voyager has complied with the restrictions of solicitation described above;

- there is a pending superior proposal;

- the Voyager board determines in good faith that this action is necessary to comply with its fiduciary duty; and

- Voyager delivers prior notice to CoreComm that it intends to take this action.

The CoreComm board has agreed to recommend to its shareholders that they approve and adopt the Voyager merger agreement.

TAX-FREE TREATMENT

Neither of CoreComm nor Voyager will take, or fail to take, or cause to be taken or fail to cause to be taken, any action, whether before or after the closing of the Voyager merger, which action or failure to take any action would cause the merger to fail to constitute a "reorganization" within the meaning of
Section 368(a) of the Internal Revenue Code or a transaction that, together with the reincorporation of CoreComm from a Bermuda corporation to a Delaware corporation, qualifies as an exchange under the provisions of Section 351 of the Internal Revenue Code and which is treated for U.S. federal income tax purposes as a transfer of Voyager common stock by the stockholders of Voyager to CoreComm in exchange for the merger consideration. However, it is further intended by CoreComm and Voyager that if the ATX merger occurs prior to the Voyager merger, and the Voyager merger agreement is assigned to post-merger CoreComm, then the ATX merger, the ATX recapitalization and the transactions described in the Voyager merger agreement will be treated for U.S. federal income tax purposes as one integrated transaction qualifying as an exchange under the provisions of
Section 351 of the Internal Revenue Code in which the stockholders of Voyager transfer Voyager common stock in exchange for post-merger CoreComm common stock.

148

CONSENTS AND APPROVALS

CoreComm and Voyager have agreed to make all necessary filings, including those under U.S. antitrust laws and under the Telecommunications Act, and to use all reasonable efforts to obtain all consents and approvals required in connection with the closing of the transactions contemplated by the Voyager merger agreement.

LISTING APPLICATION

CoreComm and Voyager have agreed to cooperate in the preparation and submission to Nasdaq of all reports, applications and other documents that may be necessary to enable all of the CoreComm common stock that will be outstanding or reserved for issuance at the effective time of the Voyager merger to be listed for trading on Nasdaq. CoreComm and Voyager will also use reasonable best efforts to cause the Voyager common stock to be de-listed from Nasdaq as soon as practicable following the effective time of the Voyager merger.

PROXY STATEMENT; REGISTRATION STATEMENT

CoreComm and Voyager will cooperate in the preparation and filing of the joint proxy statement and prospectus.

OFFICERS' AND DIRECTORS' INDEMNIFICATION

After the Voyager merger is completed, post-merger CoreComm will preserve all rights to indemnification existing as of March 12, 2000, the date of the Voyager merger agreement, in favor of any current or former director, officer or employee of Voyager for a period of at least six years following the Voyager merger. Post-merger CoreComm will also indemnify directors, officers, agents and employees of Voyager against liabilities or claims arising before the Voyager merger is completed and as a result of their positions at Voyager. Finally, post-merger CoreComm will pay the applicable persons' legal and other expenses incurred in connection with any proceeding arising out of any matter occurring until the Voyager merger is completed, and, with limitations as to cost, maintain Voyager's current directors' and officers' liability insurance in place for at least six years following the Voyager merger.

EMPLOYEE BENEFITS

Post-merger CoreComm has agreed that it will honor all obligations under the existing terms of the employment and severance agreements to which Voyager or any of

149

its subsidiaries is presently a party, except as may otherwise be agreed to by the parties to these agreements.

CoreComm has agreed that individuals who are employed by Voyager or any of its subsidiaries immediately prior to the closing of the Voyager merger will remain employees of Voyager or any of its subsidiaries, provided, that no employee will have the right to continued employment by post-merger CoreComm, Voyager or any of their respective subsidiaries for any period of time after the closing of the Voyager merger that is not otherwise required by law or contract.

To the extent that any employee of Voyager or any of its subsidiaries becomes a participant in any employee benefit plan maintained by post-merger CoreComm or any of its subsidiaries, post-merger CoreComm will, or will cause its subsidiaries to, give the affected employees full credit solely for the purposes of eligibility and vesting under its employee benefits plans for the affected employee's service with post-merger CoreComm, Voyager or any affiliate of either one to the same extent recognized immediately prior to the closing of the Voyager merger, provided, that the entry dates into the employee benefit plans for the affected employees will be in the normal course of the plan's administration, which may be the beginning of the plan year.

After the effective time of the Voyager merger, until the date post-merger CoreComm determines in its sole discretion to modify, amend, terminate or replace the benefit plans of Voyager, post-merger CoreComm will cause Voyager to maintain its benefit plans (but not bonus or equity-based plans) on substantially similar terms to those currently in effect. After the effective time of the Voyager merger, if post-merger CoreComm decides to move any employees of Voyager or its subsidiaries to a post-merger CoreComm employee benefit plan, the affected employees will be permitted to participate in the post-merger CoreComm employee benefit plan on terms substantially similar to those provided to employees of post-merger CoreComm.

REINCORPORATION

CoreComm has agreed to take any and all action that may be considered advisable or necessary to reincorporate by merger from a Bermuda corporation to a Delaware corporation so that at the time of the completion of the transactions contemplated by the Voyager merger agreement, CoreComm is a Delaware corporation.

THE ATX MERGER

CoreComm will be permitted to take any and all action that may be considered advisable or necessary to complete the ATX merger and none of the actions taken in accordance with the ATX merger or consequences of these actions will be considered a breach of a representation or warranty or be considered to cause a failure of a condition to closing to be satisfied if, but for action or consequence of the ATX merger, the condition would otherwise be satisfied.

150

OTHER ACTIONS

Prior to the effective time of the Voyager merger, Voyager and CoreComm will not, and will not permit any of their respective subsidiaries to, take any action that would, or that could reasonably be expected to, result in any of the conditions to the Voyager merger not being satisfied other than as provided in the Voyager merger agreement.

CoreComm will have the right to have its designated representatives, as provided to Voyager from time to time, upon reasonable notice, present within normal business hours and without material disruption to the business of Voyager for consultation at Voyager's principal offices until the closing of the merger. These designated representatives will have the right to review and become familiar with the conduct of the business of Voyager and will be available to be consulted and will have authority on behalf of CoreComm in regard to consultation regarding Voyager's material decisions. CoreComm will take all reasonable actions necessary to ensure that its designated representatives will be readily available during normal business hours. Voyager will not take any action involving any material decision without written notice to and favorable consultation with the designated representatives of CoreComm (which shall not be unreasonably withheld, delayed or conditioned with respect to time or content), unless CoreComm or its designated representatives have failed to respond within five business days to the written notice.

A material decision means, for purposes of the Voyager merger agreement, any of the following to the extent the decision may affect the assets, the obligations or the business of Voyager:

- any purchase order, capital expenditure or other purchase of assets in excess of $100,000 in any instance to be delivered, or the payment for which will become due, after the closing of the Voyager merger;

- the acceptance of any material customer contract or the establishment of any pricing policy that deviates in any material respect from the terms and conditions of current pricing policies as previously provided to CoreComm;

- any general communication with customers related to the business or to the Voyager merger; or

- a material change in material promotional or marketing decisions or policies.

- has notified CoreComm of its intention to enter into a binding agreement with respect to a superior proposal and, after taking into account any modifications to the transactions contemplated by the Voyager merger agreement that CoreComm has then proposed in writing and not withdrawn, the Voyager board has determined that the other proposal is and continues to be a superior proposal; and

- concurrently with the effectiveness of the termination, has paid to CoreComm the termination fee described under the section of this joint proxy statement and prospectus entitled "The Merger Agreement Between CoreComm and Voyager -- Termination Fees."

- the Voyager merger is not consummated by October 31, 2000 and Voyager is not in material breach of its obligations, or

RELATED AGREEMENTS

THE VOTING AGREEMENT

In connection with the execution of the Voyager merger agreement, the principal stockholders of Voyager (Media/Communications Partners II Limited Partnership, Media/Communication Investors Limited Partnership, Christopher P. Torto, Glenn R. Friedly, Apache Holdings II Limited Partnership and Apache Holdings Limited Partnership), who together hold approximately 63.9% of the voting power of Voyager's outstanding common stock, executed a voting agreement with CoreComm, dated as of March 12, 2000.

In the voting agreement, the principal stockholders of Voyager agreed:

- to vote their shares in favor of the Voyager merger, the Voyager merger agreement and the transactions contemplated by the Voyager merger agreement;

- to vote against any business combination other than the Voyager merger;

- not to, nor permit any person under their control to, enter into any voting agreement or grant a proxy or power of attorney with respect to their shares held of record or beneficially owned by any of them or form a group under the securities law.

In addition, the principal stockholders further agreed not to:

Furthermore, each principal stockholder agreed not to tender, sell, assign, pledge or otherwise transfer its shares of Voyager common stock and to enter into a stockholder

156

agreement upon completion of the Voyager merger, which is described below, in the event that the principal stockholder holds 7.5% or more of post-merger CoreComm common stock.

The voting agreement terminates upon the earliest to occur of:

- the closing of the transactions contemplated by the Voyager merger agreement;

- the date the Voyager merger agreement is terminated if terminated by Voyager because the shareholders of CoreComm have failed to approve the issuance of common shares of CoreComm in connection with the Voyager merger; or

- 180 days after the date the Voyager merger agreement is terminated in accordance with its terms, other than as set forth above.

THE STOCKHOLDERS AGREEMENT

In connection with the Voyager merger, each principal stockholder of Voyager will execute a stockholders agreement, the terms of which provide that, in the event that the principal stockholder holds 7.5% or more of post-merger CoreComm common stock, that principal stockholder will:

- Vote its shares in the same proportion as the votes cast by all holders of post-merger CoreComm voting securities other than the parties to this agreement and any affiliates and associates of post-merger CoreComm with respect to the applicable matter, or, in the event of a proposed change of control transaction, in the manner recommended to the stockholders by the post-merger CoreComm board of directors.

- Not deposit any voting securities in a voting trust or subject any voting securities to any voting arrangement or agreement.

- Not offer, sell, assign, pledge, encumber or dispose of or transfer any shares of post-merger CoreComm common stock prior to nine months after the date of the closing of the Voyager merger, except that the common stock may be pledged in respect of a margin loan or to a lending institution that agrees to be similarly restricted.

- Not offer, sell, assign, pledge, encumber or dispose of or transfer any voting securities, if after this action, the holder of the voting securities disposed of would own 5% or more of the aggregate voting power of all outstanding post-merger CoreComm voting securities on an as-converted basis.

158

- Generally offer, sell, assign, pledge, encumber, dispose or transfer voting securities only in the following manners:

THE REGISTRATION RIGHTS AGREEMENT

In connection with the Voyager merger, post-merger CoreComm and the principal stockholders of Voyager will enter into a registration rights agreement. Under the registration rights agreement, the principal stockholders of Voyager will be granted various registration rights with respect to post-merger CoreComm common shares issued to them in connection with the Voyager merger.

- Demand Registration Rights. The holders of at least 43.5% of the then outstanding post-merger CoreComm common stock covered by the registration rights agreement, at any time on or after six months from the date of the closing of the Voyager merger, have the right to demand that post-merger CoreComm register all or part of their registrable shares of common stock. The following conditions must be met to trigger this registration obligation:

- post-merger CoreComm is not required to effect more than one demand registration; and

159

- the number of shares of post-merger CoreComm common stock proposed to be registered by these stockholders shall not be less that 1,500,000 shares, subject to adjustment.

Post-merger CoreComm's obligation to file a demand registration statement is subject to reasonable and customary delays due to post-merger CoreComm's intentions or activities or the effectiveness of another stockholder's registration statement.

- Piggyback Registration Rights. The principal stockholders of Voyager can request to have their shares of registrable common stock registered if, at any time prior to the second anniversary of the registration rights agreement, post-merger CoreComm files a registration statement to register any of its common shares for its own account. The following conditions must be met to trigger this registration obligation:

- The number of shares that can be registered at any one time may be limited by any underwriter, if, in its opinion, the amount of common stock required to be included in the registration statement exceeds the amount that can be sold in the offering without adversely affecting the distribution.

- No piggyback registration rights apply with respect to most Forms S-8 or Forms S-4.

The number of times the piggyback registration rights may be exercised is unlimited. The registration rights agreement contains restrictions on future grants of registration rights by post-merger CoreComm that could interfere with the demand rights described above.

The registration rights agreement also contains customary provisions regarding the payment of expenses by post-merger CoreComm and mutual indemnification agreements between post-merger CoreComm and the securityholders who are parties to the registration rights agreement for securities law violations.

THE MERGER AGREEMENT BETWEEN CORECOMM AND ATX

The following is a brief summary of the significant provisions of the merger agreement between CoreComm and ATX. A copy of the ATX merger agreement is attached to and incorporated into this joint proxy statement and prospectus as Annex B. You should read the ATX merger agreement carefully and in its entirety.

GENERAL

The ATX merger agreement provides for a merger and amalgamation of CoreComm with and into a newly-formed wholly-owned subsidiary, CoreComm Merger Sub Inc., solely in order to relocate the jurisdiction of CoreComm from Bermuda to Delaware. In this domestication merger, each existing common share of CoreComm (and the accompanying right to acquire one one-hundredth of a share of CoreComm's

160

Series A Junior Preferred Stock under CoreComm's shareholders rights plan) will be exchanged for one share of common stock of the subsidiary.

Immediately following the completion of the domestication merger, the newly reincorporated CoreComm will merge directly into ATX, and ATX will be renamed "CoreComm Limited" (also referred to as post-merger CoreComm).

Simultaneously with the ATX merger, ATX will be recapitalized by having the existing ATX stockholders exchange all of the issued and outstanding shares of ATX common stock, par value $0.01 per share, for the consideration outlined below.

In the ATX merger, each issued and outstanding common share of CoreComm will be exchanged for one share of post-merger CoreComm common stock.

In the recapitalization, all of the shares of ATX common stock will be exchanged for the following aggregate consideration:

- $500.0 million of post-merger CoreComm common stock (based on the value of CoreComm common shares at the time of signing, and subject to adjustment and a collar, as discussed below);

- $250.0 million of post-merger CoreComm convertible preferred stock, (for further description of the terms and provisions of the convertible preferred stock, please read the section of this joint proxy statement and prospectus entitled "Description of the Capital Stock of post-merger CoreComm"); and

- $150.0 million in cash, of which up to $110 million may be paid in the form of three-year senior notes, at CoreComm's option, plus up to $9 million of additional three-year senior notes, if any three-year senior notes are actually issued.

The number of shares of post-merger CoreComm common stock to be issued in the ATX recapitalization is initially set assuming the price per share (based on the price per share of the CoreComm common shares during the ten trading day period before the signing of the ATX merger agreement) will equal $40.328, otherwise known as the base amount. This will result in the issuance of approximately 12.4 million shares of post-merger CoreComm common stock. However, if the volume weighted average trading price of CoreComm common shares during the ten trading days prior to the closing date of the ATX merger is greater than a specified price, known as the threshold stock price, then the number of shares of post-merger CoreComm common stock to be issued in the recapitalization will be adjusted such that the aggregate value of the post-merger CoreComm common stock received by ATX stockholders, based on the ten-day average trading price, is increased to equal the original value ($500.0 million) multiplied by a fraction, the numerator of which is the collar stock price and the denominator of which is the base amount. While the aggregate value of post-merger CoreComm common stock received in the ATX recapitalization will have increased (because the value of each share will be more than the base amount) the ATX stockholders will receive no more than, and could receive less than, the approximately 12.4 million shares discussed above.

161

The threshold stock price is determined by multiplying the base amount by 115%, with the following further adjustments:

- if the closing of the ATX merger has not occurred on or prior to July 15, 2000; and

- after the date of the ATX merger agreement, CoreComm has engaged in a transaction that would:

- require the approval of the CoreComm shareholders; or

- require CoreComm to include the information relating to the transaction in the pro forma financial statements required for the registration statement of which this proxy statement is a part; or

- require CoreComm to materially amend the pro forma financial statements; and

- all closing conditions to the ATX merger agreement have been satisfied or are capable of being satisfied with reasonable best efforts, other than the granting of all regulatory consents and/or the effectiveness of the registration statement, because of the engagement by CoreComm in a transaction other than the ATX merger,

then, commencing on the trigger date, which is the later to occur of

- July 16, 2000 and

- the first business day after which the circumstances set forth in the third bullet point in the prior paragraph are present,

the 115% will be increased as follows: 2.5 percentage points on the trigger date, and an additional five percentage points per each 31-day period beginning on the sixteenth calendar day following the trigger date. Any increase of that nature will be prorated during each such 31-day period.

In addition, the base amount of $40.328 will also be adjusted:

- upon any reclassification, recapitalization, stock split, reverse stock split, combination or exchange of shares or any dividend payable in CoreComm common shares so that the existing ATX stockholders achieve the same economic effect originally contemplated in the ATX merger agreement; and

- upon any distribution to CoreComm shareholders of, or rights or warrants for, capital stock (other than common stock), debt, other assets (other than cash dividends) or by reducing the base amount in a manner designed to reflect the decrease in value achieved by such distribution.

The ATX merger agreement provides that CoreComm, at its election, may cause up to $110 million of the $150 million payable in cash to be paid in the form of three-year senior notes. If any three-year senior notes are issued, the stockholders of ATX will be entitled to receive an additional amount in the form of three-year senior notes. This additional amount will not exceed $9 million and will be reduced proportionately to the

162

extent that less than $110 million of the cash consideration that could be paid in three-year senior notes is actually paid in three-year senior notes.

The features of these three-year senior notes are as follows:

- The notes will mature three years after the closing of the ATX merger.

- The interest rate will be set at 7% per year. Interest will be paid in cash or common stock, at post-merger CoreComm's election, on a semi-annual basis. If interest is paid in the form of common stock, either the issuance of that common stock must be covered by an effective registration statement under the Securities Act or a registration statement under the Securities Act covering the resale of that common stock must be effective as of the date of the interest payment.

- Post-merger CoreComm is permitted to prepay the notes at any time without penalty or premium.

- The notes must generally be repaid out of the net proceeds on any future equity or debt financing, excluding certain contemplated financings and the refinancing of the same. Specifically, 50% of all those net proceeds must be applied to repay the notes until $100 million in aggregate principal amount of notes is repaid. After $100 million in aggregate principal amount of notes is repaid, 100% of those net proceeds must be applied to repay the notes.

- If $110 million of the cash consideration is paid in the form of notes, post-merger CoreComm must make the following mandatory repayments:

- $2.3 million on January 1, 2001;

- $700,000 on the six-month anniversary of the closing of the ATX merger;

- $3 million on January 1, 2002; and

- $3 million on January 1, 2003.

If less than $110 million of the cash consideration is paid in the form of notes, the above-described repayments will be reduced proportionately.

If the principal amount of notes issued has been reduced, other than by payment of the above amounts, the required repayments set forth above shall be reduced proportionately and the excess shall be forgiven.

- Post-merger CoreComm will be entitled to satisfy in full all of its obligations under the notes by paying less than the full outstanding principal amount of the notes if:

- On or before December 31, 2001, post-merger CoreComm pays an amount equal to the excess of the outstanding aggregate principal amount of the notes (plus any accrued interest) over $6 million; or

- On or before December 31, 2002, post-merger CoreComm pays an amount equal to the excess of the outstanding aggregate principal amount of the notes (plus any accrued interest) over $3 million.

163

- The notes will rank senior to all subordinated indebtedness and equal with all other senior indebtedness. Post-merger CoreComm will not be permitted to incur secured indebtedness, other than vendor financing and certain other currently contemplated financing, and any refinancings of those financings, unless it secures the notes equally, to the extent that the amount of secured indebtedness is less than or equal to the amount repaid on the notes; and to the extent that the amount of that secured indebtedness is greater than the amount repaid on the notes, the notes must be given a security interest that is superior to that of the secured indebtedness.

The ATX merger agreement also provides that the aggregate consideration to be received by the existing ATX stockholders:

- is to be reduced or increased, respectively, by the amount that working capital of ATX at closing is greater or less than $0 on the earlier of the closing date and August 31, 2000;

- is to be reduced by the amount of debt of ATX at the earlier of the closing date and August 31, 2000;

- is to be reduced or increased to the extent ATX has made less than or more than approximately $5.8 million of capital expenditures between January 1 to July 31, 2000, with any increase to be limited to $1.5 million; and

- is to be reduced to the extent that ATX makes specified distributions or payments to its stockholders or is required to make transaction-related payments, including investment banking and professional fees, after August 31, 2000.

The ATX merger agreement requires the ATX stockholders to satisfy ATX's obligations to ATX employees who have rights under the ATX Phantom Unit Plan. It is currently expected that in satisfying those obligations, approximately 930,000 shares of post-merger CoreComm common stock that would otherwise be issued to the ATX stockholders in the ATX recapitalization will be delivered directly to those ATX employees in satisfaction of their rights under the ATX Phantom Unit Plan, which will be terminated at the time of the ATX recapitalization.

No certificates or scrip representing fractional shares of post-merger CoreComm common stock will be issued upon surrender for exchange of holders of CoreComm certificates. Cash will be issued instead of fractional shares of post-merger CoreComm common stock upon surrender of that certificate, along with any dividends or other distributions to which the holder is entitled, in each case without interest and less any required withholding taxes.

The ATX merger and the recapitalization are intended to qualify as exchanges and as tax-free reorganizations for federal income tax purposes.

Dissenters' rights of appraisal are not available to CoreComm's shareholders in connection with the ATX merger. However, dissenters' rights of appraisal are available to CoreComm's shareholders in connection with the domestication merger.

164

The ATX merger agreement is governed by the laws of the State of Delaware without regard to conflicts of law rules.

Except as otherwise specified in the ATX merger agreement or agreed by the parties, each party will pay all fees and expenses it incurs in the ATX merger.

POST CLOSING CAPITALIZATION

Following the ATX recapitalization and the ATX merger, post-merger CoreComm will have approximately 52.5 million shares of common stock outstanding. CoreComm's pre-merger shareholders will own approximately 76.4% of the total and ATX's current shareholders will own approximately 23.6% of the total.

Taking into account the ATX merger and the Voyager merger, post-merger CoreComm will have approximately 61.7 million shares of the common stock outstanding, CoreComm's current shareholders will own approximately 64.9% of the total, ATX's current stockholders will own approximately 20.1% of the total and Voyager's current stockholders will own approximately 15.0% of the total.

All of the percentages calculated above do not take into account any adjustments to the number of shares of post-merger CoreComm common stock that current ATX stockholders or Voyager stockholders will receive. The percentages also do not take into account the exercise of any outstanding stock options or warrants or the conversion of any convertible securities that would result in the issuance of additional common equity of CoreComm, Voyager or ATX. For more information about how the Voyager merger will affect the capitalization of post-merger CoreComm, please read "The Merger Agreements -- The Merger Agreement Between CoreComm and Voyager -- Post-Closing Capitalization."

EFFECTIVE TIME OF THE MERGER

The ATX merger will be completed upon the filing of a certificate of merger with the Secretary of State of the State of Delaware. The parties believe this will occur at the same time as the closing, which, unless the parties otherwise agree, will occur on the second business day immediately following the day on which the last of the conditions to closing are fulfilled or waived.

EXCHANGE OF CERTIFICATES

Once the ATX merger is complete, ATX will deposit with the exchange agent for the ATX merger, the certificates representing the shares of post-merger CoreComm common stock and cash issuable under the ATX merger (and cash instead of fractional shares) in exchange for outstanding CoreComm common shares.

All shares of post-merger CoreComm common stock issued upon the surrender for exchange of CoreComm common shares will be issued in full satisfaction of all rights to CoreComm common shares, except for ATX's obligation to pay any dividends or make any other distributions with a record date prior to the date the ATX merger is effected

165

which may have been declared or made by CoreComm on or prior to March 9, 2000 and that remain unpaid.

As soon as possible after the ATX merger, the exchange agent will mail a letter of transmittal and instructions to CoreComm shareholders, explaining how to surrender CoreComm common shares to the exchange agent. Upon surrender of CoreComm certificates to the exchange agent, CoreComm shareholders will be entitled to receive a certificate representing the number of whole shares of post-merger CoreComm common stock, and cash instead of any fractional share.

Post-merger CoreComm will be required to file and keep in place until all shares issued to the ATX stockholders in the ATX recapitalization may be sold in accordance with Rule 144 under the Securities Act, a shelf registration statement covering the resale of all of the securities identified above. Only one underwritten offering will be permitted to be made using the shares registered under the shelf registration.

Demand Registration Rights. At any time on or after nine months from the date of closing of the ATX merger, the holders of at least 10% of the outstanding shares of common stock subject to the agreement will have the right, exercisable only once, to demand that post-merger CoreComm register all or part of their registrable shares of common stock under the Securities Act, provided that the number of shares of common stock proposed to be registered may not be less than 1,500,000 shares as of the date of the request (subject to appropriate adjustments).

In addition, at any time after the date the registration rights agreement is executed, the holders of at least 25% of the outstanding shares of convertible preferred stock have the right, exercisable only once, to demand that post-merger CoreComm register all or

178

part of their shares of convertible preferred stock under the Securities Act. The following conditions must be met to trigger this registration obligation:

- post-merger CoreComm is not required to effect more than one such demand registration of preferred stock; and

- the stated value of the preferred shares to be registered may not be less than $80,000,000 as of the date of the request.

The requirement to file a demand registration statement is subject to reasonable and customary delays due to post-merger CoreComm's intentions or activities or effectiveness of another stockholder's registration statement.

Piggyback Registration Rights. The existing stockholders of ATX can request that their shares of registrable common stock be registered under the Securities Act if, at any time prior to the fourth anniversary of the registration rights agreement, post-merger CoreComm files a registration statement to register any of its common stock for its own account or for the account of any of its stockholders. The following conditions must be met to trigger this registration obligation:

- The number of shares that can be registered at any one time may be limited by any underwriters; and

- No piggyback registration rights apply with respect to most registration statements utilizing Forms S-8 or Forms S-4.

The registration rights agreement contains restrictions on future grants of registration rights by post-merger CoreComm that could interfere with the demand rights described above.

The registration rights agreement also contains customary provisions regarding the payment of expenses by post-merger CoreComm and mutual indemnification agreements between post-merger CoreComm and the securityholders who are parties to the registration rights agreement for security law violations.

THE TRANSITION SERVICES AGREEMENT

In connection with the ATX merger, post-merger CoreComm and University City Housing, an entity owned by Michael Karp, the Chief Executive Officer and principal stockholder of ATX, will enter into a transition services agreement providing:

- During the 12 month term of the transition services agreement, UCH or its affiliates will provide, to post-merger CoreComm or to a subsidiary, the services that are currently being provided by UCH to ATX, including, but not limited to, general accounting, cash management, taxes, payroll and human resource services, in a manner and at a level of service consistent with the services previously provided.

- Other services may be contracted by post-merger CoreComm or a subsidiary on a project-by-project basis, consistent with the specified fees.

179

- The transition services agreement may be terminated by post-merger CoreComm on 20 days' prior written notice to UCH.

THE DOMESTICATION MERGER AGREEMENT

The following is a brief summary of the significant terms and provisions of the amalgamation and merger agreement between CoreComm and its wholly-owned subsidiary, CoreComm Merger Sub, Inc. A full copy of the domestication and amalgamation merger agreement is attached as Annex C to and incorporated into this joint proxy statement and prospectus. We encourage you to read the domestication merger agreement carefully and in its entirety.

The domestication merger agreement provides for the amalgamation and merger of CoreComm into CoreComm Merger Sub, Inc. The domestication merger will occur immediately prior to the earlier of the closing of (a) the ATX merger or (b) the Voyager merger. As a result of the domestication merger CoreComm will cease to exist as a Bermuda company. Please refer to the section entitled "The Merger Transactions -- The Domestication Merger" for more information.

The certificate of incorporation and by-laws of CoreComm Merger Sub, Inc. will govern the Delaware corporation formed by the domestication merger.

In the domestication merger each issued and outstanding common share, par value $0.01 per share, of CoreComm, together with each accompanying right to acquire one one-hundredth of a share of CoreComm Series A Junior Participating Preferred Stock, shall be canceled and exchanged for one share of CoreComm Merger Sub, Inc. common stock. Each share of CoreComm Merger Sub, Inc. held by CoreComm will be cancelled for no consideration.

Appraisal Rights. Under the domestication amalgamation and merger agreement, the shares of CoreComm owned by a dissenting CoreComm shareholder who has applied for appraisal will be canceled with effect at the time of the domestication merger in consideration for the right to receive such consideration as may be payable pursuant to Bermuda law to the dissenting shareholders upon completion of the domestication merger. In the event that a dissenting shareholder fails to perfect, effectively withdraws or otherwise loses any right to appraisal and payment under Section 106 of the Companies Act, that dissenting shareholder will no longer have any right to appraisal thereunder and will be entitled to elect to receive the merger consideration.

Conditions. Each of CoreComm's and CoreComm Merger Sub, Inc.'s obligation to complete the domestication merger is subject to the certain completion of either of the ATX merger or the Voyager merger.

Directors. The directors of CoreComm will be the directors of CoreComm Merger Sub, Inc. immediately following the domestication merger.

Termination. The domestication merger agreement will automatically terminate upon the later of (a) the termination of the ATX merger agreement and
(b) the termination of the Voyager merger agreement.

CERTAIN RELATIONSHIPS AND
RELATED TRANSACTIONS FOR CORECOMM

CONFLICTS OF INTEREST

Many of CoreComm's officers and directors are also officers and directors of other companies in post-merger CoreComm's industry and some are employed by CoreComm's affiliates. Their duties to these companies may require significant amounts of their attention and may also present conflicts of interest, either of which may impede their ability to make decisions for post-merger CoreComm. Please refer to the section entitled "Risk Factors."

SERVICES PROVIDED BY NTL INCORPORATED

NTL, an historical affiliate of CoreComm, shares some resources with CoreComm, such as office space and employees. NTL will provide post-merger CoreComm and its subsidiaries with management, financial, legal and technical services, access to office space and equipment and use of supplies. Amounts charged to post-merger CoreComm by NTL will consist of salaries and direct costs allocated to post-merger CoreComm where identifiable, and a percentage of the portion of NTL's corporate overhead which cannot be specifically allocated to NTL (which will be agreed upon by post-merger CoreComm's board of directors and the board of directors of NTL). It is not practicable to determine the amounts of these expenses that would be incurred if post-merger CoreComm were to operate as an unaffiliated entity. In our opinion, this allocation method is reasonable. For the year ended December 31, 1999 and for the period from April 1, 1998 (date operations commenced) to December 31, 1998, NTL charged CoreComm $2,330,000 and $313,000, respectively.

In 1998, the percentage of NTL's non-allocated overhead that was charged to CoreComm was 30 percent. This percentage was increased to 50% because two other companies that had been sharing these expenses have been sold.

OTHER SERVICES

Through CoreComm's subsidiary, CoreComm Newco, Inc., CoreComm currently provides billing and software development services to subsidiaries of NTL, and historically provided such services to Cellular Communications of Puerto Rico, Inc., the company from which CoreComm was spun-off in 1998. We believe that these transactions are priced on an arm's length basis. General and administrative expenses were reduced by $800,000, $275,000, $138,000 and $217,000 for the year ended December 31, 1999, the period from April 1, 1998 (date operations commenced) to December 31, 1998, the period from January 1, 1998 to May 31, 1998, and the year ended December 31, 1997, respectively, as a result of these charges.

181

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS FOR ATX

ATX PROPERTIES AND FACILITIES

ATX's headquarters and executive offices and primary technical operations facility are leased from entities controlled by Michael Karp, the Chief Executive Officer and the majority stockholder of ATX. ATX currently pays approximately $1 million per year in rent for its headquarters/executive offices and approximately $450,000 per year in rent for its primary technical operations facility. The lease for ATX's primary technical operations facility currently expires in December 2002. In connection with the ATX merger, these leases are expected to be modified to reflect provisions found in arm's length negotiations for such arrangements, including, without limitation:

- the landlord will be required to give consent to a reasonable sublease, and will be entitled to all profits from that sublease;

- there will be a standard recapture right;

- there will be a standard non-disturbance clause;

- post-merger CoreComm will no longer be obligated to share facilities, employees and/or supplies with the landlord;

- existing provisions regarding the purchase of telecommunications services by landlord or other tenants from ATX/post-merger CoreComm will be eliminated; and

- existing arrangements granting the landlord a percentage of ATX's/post-merger CoreComm's revenues will be eliminated.

ATX 401(k) PLAN AND HEALTH BENEFIT PLANS

Prior to July 1, 2000 ATX's 401(k) plan and ATX's health benefit plans were joint plans with University City Housing. These plans have been amended so that employees of University City Housing do not participate in these ATX plans. It is expected that post-merger CoreComm will adopt CoreComm's existing plans and ATX's employees will be entitled to participate in those plans instead of the existing ATX plans.

ATX LIABILITY INSURANCE PLANS

ATX's liability insurance plans are held jointly with University City Housing. In connection with the ATX merger, each of ATX's liability insurance plans will be amended so that University City Housing will not be entitled to participate in these plans.

LETTERS OF CREDIT

Michael Karp has guaranteed or secured letters of credit issued by financial institutions on behalf of ATX. As of March 2000, the aggregate amount of these letters of credit is approximately $667,000. In connection with the ATX merger, arrangements will be made by CoreComm to replace the letters of credit or otherwise relieve Mr. Karp of liability under these letters of credit.

182

LOANS BY ATX TO THOMAS GRAVINA AND DEBRA BURUCHIAN

During 1999 and 2000, ATX's predecessor, two limited partnerships, made loans to Thomas Gravina, the current Co-President and a stockholder of ATX, and Debra Buruchian, the other current Co-President and also a stockholder of ATX, in the aggregate principle amounts of $2,132,842.32 each. These loans have been satisfied.

INDEBTEDNESS OF ATX TO MICHAEL KARP

The predecessor entities of ATX were indebted to Michael Karp in the aggregate principle amount of $3.6 million. Approximately $1.45 million of this amount was used to fund operating expenses of ATX. The remaining $2.15 million was used to fund acquisitions of property, plant and equipment by ATX. These loans have been retired.

PROVISION OF SERVICES TO ATX BY UNIVERSITY CITY HOUSING

University City Housing, an entity controlled by Michael Karp, currently provides general accounting, cash management, tax return preparation, payroll and human resources services to ATX. ATX pays UCH approximately 0.38% of its gross annual receipts for providing these services. For the year ended December 31, 1999, ATX paid UCH $501,000 for providing these services. For the six months ended June 30, 2000, ATX paid UCH $302,000 for these services.

In connection with the ATX merger, UCH and post-merger CoreComm will enter into a transition services agreement under which UCH will continue to provide these services to post-merger CoreComm for a limited period of time. The transition services agreement is more fully described in the section of this joint proxy statement and prospectus entitled "The Merger Agreements -- The Merger Agreement between CoreComm and ATX -- Related Agreements -- The Transition Services Agreement."

* NTL provides management, financial, legal and technical services to CoreComm. Amounts charged to CoreComm consist of salaries and direct costs allocated to the Company. In 1999 and 1998, NTL charged CoreComm $2,268,000 and $313,000, respectively. It is not practicable to determine the amounts of these expenses that would have been incurred had CoreComm operated as an unaffiliated entity. However, in the opinion of management of CoreComm, the allocation method is reasonable. The named executives, except Ms. Flynt, receive salaries from NTL and spend portions of their time providing executive management to CoreComm.

(1) Mr. Blumenthal resigned as Chief Executive Officer in March 1998, and Mr. Knapp was appointed Chief Executive Officer in March 1998.

(2) Other annual compensation consists of relocation expenses of $562,775 and $57,900 for 1999 and 1998, respectively.

(3) 1998 option grants do not include an aggregate of 508,246 options issued to the named executives as a result of an adjustment to pre-existing options in CCPR as a consequence of the spin-off. 1999 option grants do not include an aggregate of 4,110,207 options issued to the named executives as replacement options upon the exercise or cancellation of their respective warrants or options, in accordance with the plan under which these warrants or options were issued.

OPTION PLANS

Post-merger CoreComm will adopt and inherit the option plans of CoreComm. The following disclosure relates to those plans.

In 1998, CoreComm's board of directors adopted the CoreComm Limited 1998 Stock Option Plan and in 1999, CoreComm's board of directors adopted the CoreComm Limited 1999 Stock Option Plan, reserving under these plans shares for issuance to employees and directors.

The purpose of CoreComm's stock option plan is to encourage stock ownership by its employees and non-employee directors, and the employees and non-employee directors of its divisions, subsidiary corporations and other affiliates, so as to encourage its employees to continue being employed by CoreComm and to put forth maximum efforts for the success of its business. Under CoreComm's stock option plans, grants may be made of options to acquire shares of CoreComm's common stock. The options may be "incentive stock options" within the meaning of
Section 422 of the Internal Revenue Code. The terms of options granted under CoreComm's stock option plans, including provisions regarding vesting, exercisability, exercise price and duration, are generally set by the compensation committee of CoreComm's board of directors. In general, options under CoreComm's plans are 20% vested at grant and vest 20% each January 1 after they are granted, until they are fully vested.

191

In January 1999, CoreComm, Inc., one of CoreComm's wholly-owned subsidiaries, adopted a stock option plan. Options granted under that plan were not to be become exercisable unless and until there was either a registered public offering of CoreComm, Inc.'s common stock or a spin-off of CoreComm, Inc. However, under the terms of the options granted under that plan, CoreComm reserved the right to cancel the plan and issue new options in the parent company, CoreComm Limited. In March 2000, the compensation and option committee of CoreComm's board of directors approved the cancellation of the CoreComm, Inc. plan and the issuance of options in CoreComm Limited to eligible employees of CoreComm, which resulted in the issuance of options to purchase approximately 2.7 million shares of CoreComm Limited common stock. The strike prices of the new grants are approximately 30% of the fair market value of our common stock on the date of the board approval, $14.55. Eligibility for receiving the new grants was determined by, among other things, continued employment with CoreComm.

COMPARISON OF STOCKHOLDER RIGHTS

COMPARISON OF RIGHTS OF SHAREHOLDERS OF CORECOMM LIMITED (BERMUDA)
AND POST-MERGER CORECOMM

GENERAL

The rights of the holders of CoreComm common stock are currently governed by CoreComm's present memorandum of association, bye-laws and the Companies Act 1981 of Bermuda (the Companies Act). Through the domestication merger, the Bermuda company, CoreComm Limited, will become a Delaware corporation. If only the Voyager merger and not the ATX merger occurs, the resulting company will be a Delaware corporation. If the ATX merger occurs (regardless of whether the Voyager merger occurs), the resulting company will also be a Delaware corporation but will have adopted a certificate of incorporation and by-laws that are identical to those which would have been adopted by the resulting company in the Voyager merger. The following summary, which does not purport to be a complete statement of the general differences among the rights of the stockholders, sets forth material differences between the DGCL and the Companies Act, the new certificate of incorporation and by-laws to be adopted by post-merger CoreComm after consummation of the domestication merger and the Voyager and/or ATX mergers and the present memorandum of association and by-laws of CoreComm Limited. This summary is qualified in its entirety by reference to the full text of the DGCL and the Companies Act. For information as to how these documents may be obtained, see the section of this joint proxy statement and prospectus entitled "Where You Can Find More Information."

BERMUDA AND DELAWARE CORPORATE LAW

The Bermuda Companies Act, under which CoreComm was incorporated, differs in material respects from the provisions of the DGCL. Set forth below is a summary of significant provisions of the Companies Act that are materially different from the DGCL. The following statements are summaries, and do not purport to deal with all aspects of Bermuda or Delaware law that may be relevant to CoreComm and its shareholders and post-merger CoreComm and its stockholders.

AUTHORIZED CAPITAL STOCK

CoreComm had, as of July 31, 2000, 75.0 million authorized common shares, par value $0.01 per share, of which 40,161,704 were issued and outstanding and 1.0 million authorized preferred shares, par value $0.01 per share, of which none were issued and outstanding. The new certificate of incorporation and by-laws to be adopted by post-merger CoreComm will authorize the issuance of 200.0 million common shares, par value $0.01 per share, and 5.0 million preferred shares, par value $0.01 per share. If the ATX merger occurs, post-merger CoreComm will designate 250,000 preferred shares as convertible preferred stock.

VOTING RIGHTS WITH RESPECT TO EXTRAORDINARY CORPORATE TRANSACTIONS

Bermuda. Bermuda law permits amalgamation between two or more Bermuda companies (or between a Bermuda company and one or more Bermuda or foreign companies, and, subject to any requirement of the bye-laws of any of those companies, generally requires the approval, in the case of the amalgamation of non-affiliated companies, of a majority vote of three-fourths of shareholders of each of those companies present, in person or by proxy, at a meeting called for that purpose. CoreComm's bye-laws stipulate that a simple majority of the votes cast by the shareholders present, in person or by proxy, at the meeting is required to approve and any amalgamation of CoreComm with any other company. A 90% vote may be required where the amalgamation amounts to a scheme or contract under Section 102 of the Companies Act. A majority vote of shareholders is required to increase the authorized capital of a Bermuda company, but unless an increase is required, and unless there is any provision in the bye-laws to the contrary, no shareholder approval is required for the issuance of shares by an acquiring company in a share-for-share exchange, asset purchase, or, subject to the limitations set forth below, other forms of reorganization.

Delaware. Approval of mergers and consolidations and of sales, leases or exchanges of all or substantially all of the property or assets of a company, require the approval of the holders of a majority of the outstanding shares entitled to vote, except that no vote of the stockholders of a corporation surviving a merger is necessary if (a) the merger does not amend the certificate of incorporation of the corporation, (b) each outstanding share immediately prior to the effective date of the merger is to be an identical share after the merger, and (c) either no common stock of the corporation and no securities or obligations convertible into common stock are to be issued in the merger, or the common stock to be issued in the merger plus common stock initially issuable on conversion of other securities issued in the merger does not exceed 20% of the common stock of the corporation immediately before the effective date of the merger.

DISSENTERS' RIGHTS

Bermuda. Under Bermuda law, a dissenting shareholder of a company participating in extraordinary corporate transactions may, under varying circumstances, receive cash in the amount of the fair market value of its shares (as determined by a court), in lieu of the consideration it would otherwise receive in the transactions. Bermuda law generally does not condition dissenters' rights to circumstances in which a vote of the stockholders of the surviving company is required. Bermuda law, in general, provides for dissenters' rights in an amalgamation between non-affiliated companies and affiliated companies where one company is not a Bermuda company, an amendment to a company's memorandum of association, a scheme of arrangement, or reconstruction and certain other transactions. For a more thorough discussion of dissenters' rights under Bermuda law, see the section of this joint proxy statement and prospectus entitled "The Merger Transactions -- The Domestication Merger -- Appraisal Rights."

196

Delaware. Stockholders are entitled to demand appraisal of their shares in the case of mergers or consolidations, except where (a) they are stockholders of the surviving company and the merger did not require their approval under the DGCL, or (b) their shares are either listed on a national securities exchange or the Nasdaq Stock Market or held of record by more than 2,000 stockholders. Appraisal rights are available in either (a) or (b) above, however, if the stockholders are required by the terms of the merger or consolidation to accept any consideration other than (w) shares of the corporation surviving or resulting from the merger or consolidation, (x) shares of another company that are either listed on a national securities exchange or held of record by more than 2,000 stockholders, (y) cash in lieu of fractional shares, or (z) any combination of the above. Appraisal rights are not available in the case of a sale, lease, exchange or other disposition by a company of all or substantially all of its property and assets.

DERIVATIVE SUITS

Bermuda. In the event of extraordinary corporate transactions an action can be brought by minority shareholders, on behalf of a Bermuda company, seeking to enforce a right of action of that company. Under Bermuda law, a shareholder may commence a derivative action in the name of the company to remedy a wrong done to the company only (a) where the act complained of is alleged to be beyond the corporate capacity of the company or illegal, (b) where the act complained of constitutes a fraud against the minority shareholders by those controlling the company, (c) where an act requires approval by a greater percentage of the company's shareholders than actually approved it or (d) where the act infringes the personal rights of an individual shareholder. However, a derivative action will not be permitted where there is an alternative action available that would provide an adequate remedy. Any property or damages recovered by derivative action go to the company, not to the plaintiff shareholders. The Companies Act enables a shareholder who complains that the affairs of a company are being or have been conducted in a manner oppressive or prejudicial to some part of the shareholders, including itself, to petition the court. The Court will consider the interests of the shareholders in determining whether or not the company should be dissolved, with its assets distributed and may make any order it thinks fit. The Companies Act also provides that a company may be wound up by the court if the court is of the opinion that minority shareholders need relief from the oppressive conduct of the majority.

Except as mentioned above, claims against a Bermuda company by its shareholders must be based on the common law of Bermuda. A statutory right of action is conferred on subscribers to shares of a Bermuda company against persons (including directors and officers) responsible for the issue of a prospectus in respect of damage suffered by reason of an untrue statement contained in the prospectus, but this confers no right of action against the Bermuda company itself. In addition, a Bermuda company itself (as opposed to its shareholders) may take action against its officers (including directors) for breach of their statutory and fiduciary duty to act honestly and in good faith with a view to the best interests of the company.

Delaware. Derivative actions may be brought in Delaware by a stockholder on behalf of, and for the benefit of, the corporation. The DGCL provides that a stockholder

197

must state in the complaint that it was a stockholder of the corporation at the time of the transaction it is complaining about. A stockholder may not sue derivatively unless it first makes demand on the corporation that it bring suit and the demand has been refused, unless it is shown that the demand would have been futile. No suit may be brought against any officer, director, or stockholder for any debt of a corporation for which it is an officer, director, or stockholder, until judgment and execution for the action is obtained against the corporation.

SPECIAL MEETINGS OF STOCKHOLDERS

Bermuda. Under Bermuda law, a special meeting of shareholders may be convened by the shareholders at any time and must be convened upon the presence of shareholders holding not less than one-tenth of the paid-in capital of a company carrying the right to vote at general meetings.

Delaware. Stockholders generally do not have the right to call meetings of stockholders unless the right is granted in the certificate of incorporation or bylaws. However, if a company fails to hold its annual meeting within a period of 30 days after the date designated for the meeting, or if no date has been designated for a period of 13 months after its last annual meeting, the Delaware Court of Chancery may order a meeting to be held upon the formal request of a stockholder or director. The new by-laws to be adopted by post-merger CoreComm will state that the board of directors of post-merger CoreComm, the Chairman or the President may call a special meeting of stockholders but that a special meeting of stockholders may not be called by any other person or persons, including the stockholders of post-merger CoreComm.

AMENDMENTS TO CHARTER

Bermuda. Amendments to the memorandum of association and bye-laws of a Bermuda company must be submitted to a general meeting of the shareholders and will be effective only to the extent approved by the shareholders at such meeting. If the holders of not less than 20% in par value of the shares do not support the amendments they may apply to a court to annul the amendment within twenty-one days of the resolution amending the memorandum. The present by-laws require a 66 2/3% vote to amend some of their provisions.

Delaware. Amendments to the certificate of incorporation require the affirmative vote of the holders of a majority of the outstanding shares entitled to vote on that matter; except that if the certificate of incorporation requires the vote of a greater number or proportion of the holders of any class of stock than is required by Delaware law with respect to any matter, the provision of the certificate of incorporation may not be amended, altered or repealed except by the greater vote required. In addition, the holders of the outstanding shares of a class are entitled to vote as a class on any amendment to the certificate of incorporation, whether or not they are entitled to vote on that matter by the certificate of incorporation, if the amendment would increase or decrease the aggregate number of authorized shares of the class, increase or decrease the par value of the shares of the class or alter or change the powers, preferences or special

198

rights of the class so as to affect them adversely. The new certificate of incorporation and new by-laws will require a 66 2/3% vote to amend some of its provisions.

ANTI-TAKEOVER STATUTES

Bermuda. Bermuda does not currently have a tender offer statute. However, the Companies Act provides that where an offer is made for shares in a company by another company and, within four months of the offer, the holders of not less than 90% in value of the shares that are the subject of the offer accept it, the offeror may by notice, given within two months after the expiration of the four months, require that dissenting shareholders transfer their shares under the terms of the offer. Dissenting shareholders may apply to a court within one month of the notice objecting to the transfer, and the court may give any order as it thinks fit. The Companies Act also provides that the holders of not less than 95% of the shares of any class of shares in a company may give notice to the remaining shareholders or class of shareholders of the intention to acquire their shares on the terms set out in the notice. Recipients of the notice have a right to apply to the Bermuda courts for an appraisal.

Delaware. Generally, Section 203 of the DGCL prohibits a publicly held Delaware company from engaging in a "business combination" with an "interested stockholder" for a period of three years after the date of the transaction in which the person became an interested stockholder, unless (a) prior to such time, the board of directors of the corporation approved either the business combination or the transaction that resulted in the stockholder becoming an interested stockholder, (b) upon completion of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder owns at least 85% of the outstanding voting stock (with certain exclusions), or
(c) on or after such date the business combination is approved by the board of directors and by the affirmative vote of at least 66 2/3% of the outstanding voting shares that is not owned by the interested stockholder. An "interested stockholder" is a person who, together with affiliates or associates, owns 15% or more of the corporation's voting stock.

LIMITATIONS ON DIRECTOR LIABILITY

Bermuda. Under Bermuda law, a director must observe the statutory duty of care, which requires such director to act honestly and in good faith with a view to the best interests of a company and exercise the care, diligence and skill that a reasonably prudent person would exercise in comparable circumstances. Bermuda law renders void any provision in the bye-laws or any contract between a company and any such director exempting it from or indemnifying it against any liability for fraud or dishonesty of which it may be guilty in relation to that company.

Delaware. Under Delaware law, a company may include in its certificate of incorporation, a provision eliminating or limiting the liability of a director to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, provided that a company may not eliminate or limit the liability of a director (a) for any breach of the director's duty of loyalty to the corporation or its stockholders,

199

(b) for acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law, (c) acts concerning unlawful payments of dividends or stock purchases or redemptions under Section 174 of the DGCL, or
(d) for any transactions from which a director derived an improper personal benefit. The new certificate of incorporation will contain some provisions which will limit the liability of post-merger CoreComm's board of directors as permitted under Delaware law.

INDEMNIFICATION OF DIRECTORS AND OFFICERS

Bermuda. Under Bermuda law, a company is permitted to indemnify its officers and directors, out of the funds of the company, against any liability incurred by them in defending any proceedings, whether civil or criminal, in which judgment is given in their favor, or in which they are acquitted, or in connection with any application under relevant Bermuda legislation in which relief from liability is granted to them by the court. The present by-laws contain provisions regarding the indemnification of the officers and directors of CoreComm as permitted under Bermuda law.

Delaware. Under Delaware law, a company is permitted to indemnify its officers, directors and certain others against any liability or expenses incurred in any civil, criminal, administrative or investigative proceeding if they acted in good faith and in a manner they reasonably believed to be in or not opposed to the best interests of the corporation and, with respect to any criminal proceeding, had no reasonable cause to believe their conduct was unlawful, except that in any action brought by or in the right of the corporation, such indemnification may be made only for expenses (not judgments or amounts paid in settlement) and may not be made even for expenses if the officer, director or other person is adjudged liable to the corporation (unless otherwise determined by the court). In addition, under Delaware law, to the extent that a director or officer of a company has been successful on the merits or otherwise in defense of any proceeding referred to above, it must be indemnified against expenses (including attorneys' fees) actually and reasonably incurred by that party. The new by-laws will contain provisions relating to the indemnification of post-merger CoreComm's officers and directors.

INSPECTION OF BOOKS AND RECORDS; SHAREHOLDER LISTS

Bermuda. Bermuda law provides the general public with a right of inspection of a Bermuda company's public documents at the office of the Registrar of Companies in Bermuda, and provides a Bermuda company's shareholders with a right of inspection of the company's bye-laws, minutes of general (shareholder) meetings, and audited financial statements. The register of shareholders is also open to inspection by shareholders free of charge and, upon payment of a small fee, by any other person. A Bermuda company is required to maintain its share register in Bermuda but may, in certain circumstances, establish a branch register outside of Bermuda. A Bermuda company is required to keep at its registered office a register of its directors and officers that is open for inspection by members of the public without charge. Bermuda law does not, however, provide a general right for shareholders to inspect or obtain copies of any other corporate records.

200

Delaware. Any stockholder of record, in person or by attorney or other agents, upon written demand under oath stating the purpose of the demand, has the right during the corporation's usual hours for business to inspect, for any proper purpose, the corporation's stock ledger, a list of its stockholders, and its other books and records, and to make copies or extracts from these documents.

PREEMPTIVE RIGHTS

Bermuda. Under Bermuda law, no shareholder has a preemptive right to subscribe for additional issues of a company's shares unless, and to the extent that, the right is expressly granted to the shareholder under the bye-laws of a company or under any contract between the shareholder and the company.

Delaware. Under Delaware law, no stockholder has a preemptive right to subscribe to additional issues of a corporation's stock unless, and to the extent that, the right is expressly granted to the stockholder in the corporation's certificate of incorporation. The new certificate of incorporation will not provide for preemptive rights.

DIVIDENDS

Bermuda. Bermuda law permits payment of dividends and distributions of contributed surplus by a company unless the company, after the payment is made, would be unable to pay its liabilities as they become due, or the realizable value of the company's assets would be less, as a result of the payment, than the aggregate of its liabilities and its issued share capital and share premium accounts. The excess of the consideration paid on the issuance of shares over the aggregate par value of the shares must (except in certain limited circumstances) be credited to a share premium account. Share premium may be distributed in limited circumstances, for example to pay up unissued shares that may be distributed to shareholders in proportion to their holdings, but is otherwise subject to limitation.

Delaware. Delaware law generally allows dividends to be paid out of surplus of the corporation or out of the net profits of the corporation for the current fiscal year and/or the prior fiscal year. No dividends may be paid if they would result in the capital of the corporation being less than the capital represented by the preferred shares of the corporation.

VOTING RIGHTS AND QUORUM REQUIREMENTS

Bermuda. Under Bermuda law, in the absence of any other agreement to the contrary, the voting rights of shareholders are regulated by the present by-laws. The by-laws now in place for CoreComm specify that at least two shareholders present in person or by proxy and entitled to vote representing the holders of more than 50% of the issued shares shall be a quorum for all purposes which is required to transact business. Under the present by-laws, any shareholder of CoreComm who is present at a meeting may vote in person or by proxy and each shareholder is entitled to one vote for each CoreComm share owned.

201

Delaware. Under the DGCL and the new certificate of incorporation to be adopted by post-merger CoreComm, each holder of common shares will be entitled to one vote per share. A quorum will be satisfied when enough holders of the capital stock issued and outstanding and entitled to vote are present at an annual or special meeting, in person or by proxy, to cast a majority of the votes entitled to be cast by the stockholders. The new by-laws will provide that all matters which require a vote by the stockholders may (but need not) be by written ballot, and this determination will be made at the discretion of post-merger CoreComm's board of directors or the officer presiding at the meeting.

NUMBER AND QUALIFICATIONS OF DIRECTORS; SIZE OF BOARD

Bermuda. Under Bermuda law, the minimum number of directors on the board of directors of a company is two, although the minimum number of directors may be set higher and the maximum number of directors may also be set in accordance with the bye-laws of the company. The exact number of directors is usually fixed by the shareholders in general meeting. Only the shareholders may increase or decrease the number of director seats last approved by the shareholders.

The present by-laws of CoreComm set forth that the directors shall be divided into three classes, designated Class I, Class II and Class III and each class shall consist, as nearly as may be possible, of one-third of the total number of directors constituting the entire board. The term of the initial Class I directors shall terminate on the date of the year 2000 annual meeting; the term of the initial Class II Directors shall terminate on the date of the year 2001 annual meeting and the terms of the initial Class III directors shall terminate on the date of the year 2002 annual meeting of shareholders. At each annual meeting beginning in 2000, successors to the class of directors whose term expires at that annual meeting shall be elected for a three-year term. If the number of directors is changed, any increase or decrease shall be apportioned among the classes so as to maintain the number of directors in each class as nearly equal as possible.

The present by-laws of CoreComm set forth that the minimum number of directors shall be not less than three (3) and the maximum number of directors shall be fifteen (15). The current size of the board of directors of CoreComm is currently fixed at 8. The current by-laws also provide that whenever the holders of any one or more classes or series of preference shares issued by CoreComm shall have the right to elect directors at an annual or special meeting of shareholders, the election shall be governed by the terms of resolutions adopted by the board of directors at the time the class of preference shares is established.

Delaware. Under Delaware law, the minimum number or directors is one. The number of directors constituting the board of directors of a Delaware corporation may be specified in the bylaws or the certificate of incorporation. Accordingly, unless the certificate of incorporation provides otherwise, the directors may change the number of directors constituting the board by amending the bylaws. If the number of directors is specified in the certificate of incorporation, then any change in the number of directors must be made through a certificate of amendment approved by the stockholders.

202

The number of directors for post-merger CoreComm will be set in the new by-laws. The board of directors of post-merger CoreComm will be classified in the same manner as the board of directors of CoreComm.

REMOVAL OF DIRECTORS

Bermuda. Subject to its bye-laws the shareholders of a Bermuda company may, at a special general meeting called for the purpose, remove any director or the entire board of directors provided that notice of the meeting will be served on the director or directors concerned not less than fourteen days before such meeting. Any director given notice of removal will be entitled to be heard at the meeting. The present by-laws provide that directors may be removed from office for cause by the affirmative vote of at least a majority of the shares entitled to vote for the election of directors.

Delaware. Unless a corporation's certificate of incorporation provides otherwise and except in the case of a classified board of directors or where cumulative voting applies, Delaware law allows directors of a corporation to be removed with or without cause by the vote of the holders of a majority of the shares entitled to vote in any election of directors.

The new certificate of incorporation to be adopted by post-merger CoreComm will provide that directors may be removed only for cause by the affirmative vote of the holders of at least two-thirds (66 2/3%) of the outstanding shares of post-merger CoreComm then entitled to vote generally in the election of directors.

COMPARISON OF RIGHTS OF STOCKHOLDERS OF POST-MERGER CORECOMM AND VOYAGER

The rights of Voyager stockholders are currently governed by the Delaware General Corporation Law, or DGCL, Voyager's second amended and restated certificate of incorporation and Voyager's by-laws. The rights of post-merger CoreComm stockholders will be governed by the DGCL, post-merger CoreComm's certificate of incorporation and post-merger CoreComm's by-laws. Voyager's by-laws and second amended and restated certificate of incorporation and post-merger CoreComm's by-laws and certificate of incorporation are also sometimes referred to as charter documents. The following is a summary of material differences between the rights of Voyager stockholders and the rights of post-merger CoreComm stockholders. It is not a complete statement of the provisions affecting, and the differences between, the rights of Voyager stockholders and post-merger CoreComm stockholders. The summary is qualified in its entirety by reference to the DGCL, Voyager's second amended and restated certificate of incorporation and by-laws, and post-merger CoreComm's certificate of incorporation and by-laws.

FILLING VACANCIES ON THE BOARD OF DIRECTORS

Voyager. The Voyager by-laws provide that any vacancies in the board of directors, however resulted, shall be filled solely by the affirmative vote of a majority of the remaining directors then in office, even if less than a quorum of the board of directors.

Post-merger CoreComm. Post-merger CoreComm's certificate of incorporation will prohibit stockholder action by written consent in lieu of a stockholder meeting.

LIMITATION OF PERSONAL LIABILITY OF DIRECTORS AND INDEMNIFICATION

Voyager. Voyager's second amended and restated certificate of incorporation provides that a director will not be personally liable to Voyager or to its stockholders for monetary damages for breach of fiduciary duty as a director, except, if required by law, for liability; for any breach of the director's duty of loyalty to Voyager or its stockholders; for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law; under Section 174 of the Delaware General Corporation Law; and for any transaction from which the director derived an improper personal benefit. Voyager's second amended and restated certificate of incorporation provides a right to indemnification to directors and officers of Voyager to the fullest extent permitted by the DGCL. In addition, Voyager must indemnify any present or former director or officer of Voyager who or any person who is or was serving at the request of Voyager as a director, officer, employee or agent of another corporation who has been successful on the merits or otherwise in the defense of any claim or proceeding for expenses (including attorneys' fees) actually and reasonably incurred.

206

corporation, partnership, joint venture, trust, employee benefit plan or other enterprise, will be indemnified by post-merger CoreComm to the full extent permitted by the DGCL.

DIVIDENDS

Voyager. Voyager's second amended and restated certificate of incorporation provides that the board of directors, or an authorized committee of the board of directors, may, in designating the terms of a series of preferred stock, state the conditions upon which the holders of the series of preferred stock shall be entitled to receive dividends. The common stockholders shall be entitled to dividends only if the board of directors, or an authorized committee of the board of directors, declares dividends and as may be permitted by law.

Post-merger CoreComm. Post-merger CoreComm's certificate of incorporation will provide that the board of directors may state the conditions upon which the holders of a series of preferred stock shall be entitled to receive dividends. Post-merger CoreComm's certificate of incorporation will also provide that the common stockholders will be entitled to dividends as may be permitted by law.

AMENDMENTS TO CERTIFICATE OF INCORPORATION

Voyager. Voyager's second amended and restated certificate of incorporation provides that the certificate of incorporation may be amended by the affirmative vote of the majority of the outstanding shares entitled to vote on the amendment or repeal, and the affirmative vote of the majority of the outstanding shares of each class entitled to vote on that matter as a class, at a meeting of stockholders called expressly for that purpose.

The post-merger CoreComm certificate of incorporation will also provide that amendments to certain provisions of the certificate of incorporation will require the approval of the holders of 66 2/3% of the stock entitled to vote on the amendment.

207

AMENDMENTS TO BY-LAWS

Voyager. The Voyager by-laws provide that the by-laws may be amended or repealed by the board of directors by the affirmative vote of a majority of the directors then in office. The by-laws may also be amended or repealed at any annual meeting, or special meeting of stockholders called for that purpose, by the affirmative vote of at least two-thirds (66 2/3%) of the shares present in person or represented by proxy at the meeting and entitled to vote on the amendment or repeal, voting together as a single class. However, if the board of directors recommends that stockholders approve an amendment or repeal at a meeting of stockholders, that amendment or repeal shall only require the affirmative vote of the majority of the shares present in person or represented by proxy at the meeting and entitled to vote on the amendment or repeal, voting together as a single class.

Post-merger CoreComm. Post-merger CoreComm's certificate of incorporation will provide that the by-laws may be altered, amended or repealed, in whole or in part, or new by-laws may be adopted by either the affirmative vote of the holders of sixty-six and two-thirds percent (66 2/3%) of the outstanding capital stock of post-merger CoreComm entitled to vote on that matter or by a resolution adopted by the board of directors.

208

DESCRIPTION OF THE CAPITAL STOCK OF POST-MERGER CORECOMM

GENERAL

Post-merger CoreComm's authorized capital stock will consist of 200,000,000 shares of common stock, par value $0.01 per share, and 5,000,000 shares of preferred stock, par value $0.01 per share.

POST-MERGER CORECOMM COMMON STOCK

The holders of post-merger CoreComm's common stock will be entitled to one vote for each share held of record on all matters submitted to a vote of post-merger CoreComm's stockholders and do not have cumulative voting rights in the election of directors. Holders of post-merger CoreComm common stock will be entitled to receive proportionately dividends as may from time to time be declared by post-merger CoreComm's board of directors out of funds legally available for the payment of dividends. In the event of post-merger CoreComm's liquidation, dissolution or winding up, holders of post-merger CoreComm common stock would be entitled to share proportionately in all of post-merger CoreComm's assets available for distribution to holders of post-merger CoreComm common stock remaining after payment of liabilities and liquidation preference of any outstanding post-merger CoreComm preferred stock. Holders of post-merger CoreComm common stock will have no preemptive rights and will have no rights to convert post-merger CoreComm common stock into any other securities, and there will be no redemption provisions with respect to the common stock.

PREFERRED STOCK

The by-laws of post-merger CoreComm will authorize the board of directors to issue one or more series of preferred stock and determine, with respect to any series rights, if any, and their qualifications, limitations or restrictions, as are stated in resolutions adopted by the board of directors providing for the issue of the series and as are permitted by the DGCL.

The ability of the board of directors to issue one or more series of preferred stock will provide increased flexibility in structuring possible future financings and acquisitions and in meeting other corporate needs which might arise. The authorized shares of preferred stock, as well as shares of post-merger CoreComm common stock, will be available for issuance without further action by post-merger CoreComm stockholders, unless such action is required by applicable law or the rules of any stock exchange or automated quotation system on which post-merger CoreComm securities may be listed or applicable rules of any self-regulatory organization. If the approval of post-merger CoreComm stockholders is not required for the issuance of shares of preferred stock or common stock, the board of directors does not intend to seek stockholder approval. The board of directors will make any determination to issue the shares based on its judgment as to post-merger CoreComm's best interests and the best interests of its stockholders. The board of directors, in so acting, could issue preferred stock having terms that could discourage an acquisition attempt or other transaction that some or a majority of the

209

stockholders might believe to be in their best interests or in which stockholders might receive a premium for their shares over the then current market price of such shares.

SPECIAL CHARTER PROVISIONS

Post-merger CoreComm's certificate of incorporation, which post-merger CoreComm refers to as the "charter," will contain the provisions described below. Those charter provisions may have the effect, alone or in combination with each other or with the existence of authorized but unissued common stock and any series of preferred stock, of precluding or rendering more difficult a hostile takeover, making it more difficult to remove or change the composition of post-merger CoreComm's incumbent board of directors and its officers, being adverse to stockholders who desire to anticipate in a tender offer and depriving stockholders of possible opportunities to sell their shares at temporarily higher prices.

Classified board and filling of vacancies on the board of directors. The charter will provide that the directors shall be divided into three classes, each of which shall serve a staggered three-year term, and that vacancies on post-merger CoreComm's board of directors that may occur between annual meetings may be filled by post-merger CoreComm's board of directors. In addition, this provision will specify that any director elected to fill a vacancy on post-merger CoreComm's board of directors will serve for the balance of the term of the replaced director.

Removal of directors. The charter will provide that directors can be removed only by the stockholders for cause and then only by the affirmative vote of the holders of not less than two-thirds (66 2/3%) of post-merger CoreComm's combined voting power.

Voting requirement for some business combinations. The charter will also provide that, in addition to any affirmative vote required by law, the affirmative vote of holders of two-thirds (66 2/3%) of post-merger CoreComm's voting power will be necessary to approve any "business combination," as defined below, proposed by an "interested stockholder," as defined below. The additional voting requirements will not apply, however, if:

- the business combination was approved by not less than a majority of the continuing directors;

- a series of conditions are satisfied requiring, in summary, the following:

(A) that the consideration to be paid to post-merger CoreComm's stockholders in the business combination must be at least equal to the higher of:

(1) the highest per-share price paid by the interested stockholder in acquiring any shares of common stock during the two years prior to the announcement date of the business combination or in the transaction in which it became an interested stockholder, this date is referred to as the "determination date," whichever is higher; or

(2) the fair market value per share of common stock on the announcement date or determination date, whichever is higher, in either case

210

appropriately adjusted for any stock dividend, stock split, combination of shares or similar event with non-cash consideration treated similarly; and

(B) various "procedural" requirements are complied with, including the consent solicitation of proxies according to the rules of the SEC and no decrease in regular dividends, if any, after the interested stockholder became an interested stockholder, except as approved by a majority of the continuing directors.

An "interested stockholder" is defined as anyone who is the beneficial owner of more than 15% of the voting power of the voting stock, other than post-merger CoreComm and any employee stock plans sponsored by post-merger CoreComm, and includes any person who is an assignee of or has succeeded to any shares of voting stock in a transaction not involving a public offering that were at any time within the prior two-year period beneficially owned by an interested stockholder. The term "beneficial owner" includes persons directly and indirectly owning or having the right to acquire or vote the stock. Interested stockholders participate fully in all stockholder voting.

A "business combination" includes the following transactions:

- merger or consolidation of post-merger CoreComm or any subsidiary of post-merger CoreComm with an interested stockholder or with any other corporation or entity which is, or after the merger or consolidation would be, an affiliate of an interested stockholder;

- the sale or other disposition by post-merger CoreComm or a subsidiary of post-merger CoreComm of assets having a fair market value of $5,000,000 or more if an interested stockholder, or an affiliate of an interested stockholder is a party to the transaction;

- the adoption of any plan or proposal for post-merger CoreComm's liquidation or dissolution proposed by or on behalf of an interested stockholder, or an affiliate of an interested stockholder; or

- any reclassification of securities, recapitalization, merger with a subsidiary, or other transaction which has the effect, directly or indirectly, of increasing the proportionate share of any class of post-merger CoreComm's outstanding stock, or securities convertible in to stock, or a subsidiary owned by an interested stockholder, or an affiliate of an interested stockholder.

Determinations of the fair market value of non-cash consideration are made by a majority of the continuing directors.

The term "continuing directors" means any member of post-merger CoreComm's board of directors, while that person is a member of post-merger CoreComm's board of directors, who is not a affiliate or associate or representative of the interested stockholder and was a member of post-merger CoreComm's board of directors prior to the time that the interested stockholder became an interested stockholder, and any successor of a continuing director while that successor is a member of the post-merger CoreComm's

211

board of directors, who is not an affiliate or associate or representative of the interested stockholder and is recommended or elected to succeed the continuing director by a majority of continuing directors.

Voting requirements for some amendments to the charter. The charter will provide that the provisions set forth in this section under the heading "Special Charter Provisions" may not be repealed or amended in any respect, unless that action is approved by the affirmative vote of the holders of not less than two-thirds (66 2/3%) of post-merger CoreComm's voting power. The requirement of an increased stockholder vote is designed to prevent a stockholder who controls a majority of post-merger CoreComm's voting power from avoiding the requirements of the provisions discussed above by simply amending or repealing those provisions.

THE SHAREHOLDER RIGHTS PLAN

CoreComm currently has a shareholder rights plan in effect but concurrently with the domestication merger, the common shares of CoreComm and the rights attached to the shares will be exchanged for common stock of post-merger CoreComm. The current CoreComm shareholder rights plan will therefore be canceled by CoreComm. After the domestication merger and the ATX and Voyager mergers are consummated, the board of directors of post-merger CoreComm may adopt a shareholder rights plan. Any such plan would likely be substantially identical to the one currently in place by CoreComm. Adoption of a new shareholder rights plan by post-merger CoreComm will occur only if the domestication merger occurs.

The terms and provisions of the CoreComm shareholder rights plan have various anti-takeover effects as they cause substantial dilution to a person or group that attempts to acquire a substantial interest in CoreComm without the prior approval of the board of directors. Among the effects of the shareholder rights plan is that the rights from the shareholder rights plan could discourage a takeover attempt that might otherwise allow the holders of CoreComm common shares to sell their shares at a premium to the then current market price or which might otherwise be beneficial to shareholders. If a similar plan is adopted by post-merger CoreComm, these anti-takeover provisions in the shareholder rights plan could also have a material adverse effect on the premium that potential acquirors might be willing to pay in an acquisition or that investors might be willing to pay in the future for shares of post-merger CoreComm's common stock. For further discussion of the risk factors associated with the shareholder rights plan, please refer to the section of this joint proxy statement and prospectus entitled "Risk Factors -- Risk Factors relating to post-merger CoreComm's capital structure -- Post-merger CoreComm will have anti-takeover defense provisions that may deter potential acquirors and depress its stock price."

For more information regarding the shareholder rights plan of CoreComm, please refer to the description of the plan in the Registration Statement on Form 10, filed by CoreComm with the Securities and Exchange Commission on June 24, 1998 or refer to the plan itself, included as an exhibit to the Registration Statement on Form 10-12G, filed by CoreComm with the SEC on August 19, 1998 and Amendments Number One

212

and Two to the shareholder rights plan, included as exhibits to the Form 10-K filed by CoreComm with the SEC on March 29, 2000.

TRANSFER AGENT AND REGISTRAR

Post-merger CoreComm's transfer agent and registrar for the common stock will be Continental Stock Transfer & Trust Company.

SECTION 203 OF THE DELAWARE GENERAL CORPORATION LAW

Generally, Section 203 of the Delaware General Corporation Law prohibits a publicly held Delaware corporation from engaging in any business combination with an interested stockholder for a period of three years following the time that a stockholder becomes an interested stockholder, unless:

- prior to that time either the business combination or the transaction which resulted in the stockholder becoming an interested stockholder is approved by the board of directors of the corporation;

- upon consummation of the transaction which resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, excluding, for purposes of determining the number of shares outstanding, those shares held by persons who are both directors and officers and certain employee stock plans; or

- at or after that time the business combination is approved by the board and authorized at an annual or special meeting of stockholders, and not by written consent, by the affirmative vote of at least two-thirds of the outstanding voting stock which is not owned by the interested stockholder.

A business combination includes certain mergers, consolidations, asset sales, transfers and other transactions resulting in a financial benefit to the interested stockholder. An interested stockholder is a person who, together with affiliates and associates, owns 15% or more of the corporation's voting stock.

INDEMNIFICATION PROVISIONS

Section 145 of the Delaware General Corporation Law authorizes a corporation to indemnify its directors, officers, employees and agents against expenses (including attorneys' fees), judgments, fines and amounts paid in settlement reasonably incurred, including liabilities under the Securities Act, provided they act in good faith and in a manner reasonably believed to be in or not opposed to the best interests of the corporation, although in the case of proceedings brought by or on behalf of the corporation, such indemnification is limited to expenses and is not permitted if the individual is adjudged liable to the corporation (unless the court determines otherwise). The registrant's Certificate of Incorporation and Bylaws require the registrant to indemnify its officers and directors to the full extent permitted by Delaware law.

213

Section 102 of the Delaware General Corporation Law authorizes a corporation to limit or eliminate its directors' liability to the corporation or its stockholders for monetary damages for breaches of fiduciary duties, other than for (i) breaches of the duty of loyalty, (ii) acts or omissions not in good faith or that involve intentional misconduct or knowing violations of law, (iii) unlawful payments of dividends, stock purchases or redemptions, or (iv) transactions from which a director derives an improper personal benefit. The registrant's Certificate of Incorporation contains provisions limiting the liability of the directors to the registrant and to its stockholders to the full extent permitted by Delaware law.

Section 145 of the Delaware General Corporation Law authorizes a corporation to purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the corporation against any liability asserted against him or her and incurred by him or her in any such capacity, or arising out of his or her status as such. The registrant's Certificate of Incorporation and Bylaws provide that the registrant may, to the full extent permitted by law, purchase and maintain insurance on behalf of any director, officer, employee or agent of the registrant against any liability that may be asserted against him or her and the registrant currently maintains such insurance. The registrant will obtain liability insurance covering its directors and officers for claims asserted against them or incurred by them in such capacity, including claims brought under the Securities Act.

Insofar as indemnification for liabilities arising from the Securities Act may be permitted to directors, officers or persons controlling the registrant pursuant to the foregoing provisions, the registrant has been informed that in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

CONVERTIBLE PREFERRED STOCK

As part of the recapitalization of ATX occurring simultaneously with the ATX merger, the ATX stockholders will create a series of convertible preferred stock to be issued to its existing stockholders, with the material terms and conditions as are described below.

Dividends. Each share of convertible preferred stock entitles its holder to receive dividends out of funds of the corporation legally available for the payment of dividends prior to and in preference to any declaration or payment of any dividend on any securities junior in dividend rights to the convertible preferred stock (other than dividends payable in the form of those junior securities or securities convertible into those junior securities) and on a parity with any securities that are designated to be on a parity with the convertible preferred stock. Dividends are payable when and as authorized and declared by the board of directors of post-merger CoreComm. Dividends on each share of convertible preferred stock accrue at the rate determined as described below on the liquidation value of $1,000 per share. The dividend on the convertible preferred stock is cumulative and is payable in arrears on the anniversary of the date of issuance of the convertible preferred stock. Dividends accrue whether or not they have

214

been declared and whether or not there are profits, surplus or other funds of post-merger CoreComm legally available for the payment of dividends.

At the sole discretion of post-merger CoreComm, dividends may be paid either in cash or in shares of common stock. If paid in shares of post-merger CoreComm common stock, the amount of common stock to be paid will be calculated assuming such common stock has a value equal to 98% of the volume weighted average sale price during the prior 5 trading days immediately preceding the dividend payment date.

Post-merger CoreComm may not pay any dividends on any junior securities, other than dividends payable in the form of those junior securities, unless all accrued and unpaid dividends required to be paid on the convertible preferred stock and any parity securities as of the immediately prior scheduled dividend payment date have been paid in full and sufficient funds have been set aside for the next scheduled dividend payment date. Likewise, post-merger CoreComm may not redeem, acquire or repurchase any junior securities, except as required to comply with an employee incentive or benefit plan, unless it is current in its dividend payments on the convertible preferred stock and sufficient funds have been set aside for the next scheduled dividend payment date.

The dividend rate on the convertible preferred stock will be 3% per year for the first 12 months after the issuance of the three-year senior notes in the ATX merger. If any three-year senior notes remain outstanding as of the end of that period, the rate increases to 5% per year. If any three-year senior notes remain outstanding as of 18 months after the issuance of the three-year senior notes in the ATX merger, the rate increases to 7% per year. The amount of dividends payable for any period shorter or longer than a full year will be computed daily on the basis of a 360-day year. Dividends will be payable quarterly.

Liquidation, Dissolution or Winding up; Mergers, Consolidations and Asset Sales. In the event of any voluntary or involuntary liquidation, dissolution or winding up of post-merger CoreComm, the holders of convertible preferred stock then outstanding will be entitled to be paid out of the assets of post-merger CoreComm available for distribution to its stockholders after payment of any liquidation values of any securities senior in liquidation rights to the convertible preferred stock and before any securities junior in liquidation rights to the convertible preferred stock.

If, upon any liquidation, dissolution or winding up of post-merger CoreComm, the remaining assets of post-merger CoreComm available for distribution to its stockholders are insufficient to pay the holders of convertible preferred stock and all other classes or series of stock ranking equal to it with respect to liquidation the full amount to which they are entitled, the holders of convertible preferred stock and, together with holders of the equally preferenced stock, will share ratably (based on their relative liquidation values) in any distribution of the remaining assets and funds of post-merger CoreComm.

The voluntary consolidation or merger of post-merger CoreComm into another entity, or the sale of all or substantially all of the assets of post-merger CoreComm is not a liquidation or dissolution with respect to the convertible preferred stock.

215

Voting Rights. Except as otherwise provided below or as otherwise provided by law, holders of convertible preferred stock are not entitled to vote.

Post-merger CoreComm will not (a) alter, amend or repeal the preferences, special rights or other powers or privileges of the convertible preferred stock, or (b) create any class or series of securities senior to the convertible preferred stock without the written consent or affirmative vote of holders of a majority of the then outstanding shares of convertible preferred stock.

Mandatory Redemption. The convertible preferred stock is mandatorily redeemable by post-merger CoreComm on the twentieth anniversary of its date of issuance, to the extent there are funds legally available for such payment. At such time, post-merger CoreComm will redeem all shares of the convertible preferred stock at a redemption price of $1,000 per share, payable together with accrued and unpaid dividends either, in the sole discretion of post-merger CoreComm, in cash or in shares of common stock. If paid in shares of post-merger CoreComm common stock, the amount of common stock to be paid will be calculated assuming the common stock has a value equal to 98% of the volume weighted average sale price during the five trading days immediately preceding the redemption date.

All holders of record of convertible preferred stock will be given written notice of the redemption and the date and place for the redemption not less than 30 days nor more than 60 days prior to the redemption date. Each holder of convertible preferred stock will surrender that holder's certificates representing the convertible preferred stock to post-merger CoreComm at the place designated in the notice, and on the later of the date for the redemption and the date the certificates are surrendered, will receive the payment to which it is entitled.

On the redemption date, assuming notice has been provided in accordance with the paragraph above, all rights with respect to the convertible preferred stock, will terminate, except for the right of the holders of that stock to receive the redemption price (in cash or common stock).

Conversion Rights.

Conversion at the Option of Post-merger CoreComm. Beginning any time after the second anniversary of the initial issuance date of the convertible preferred stock, if the average current market price of the common stock for 20 consecutive trading days is at least 125% of the conversion price as of such time, post-merger CoreComm can require the conversion of the convertible preferred stock into that number of shares of common stock as is determined by dividing the liquidation value of the shares by a number equal to the conversion price as of that time. Similarly, at any time after the fifth anniversary, if the current market price is equal to or greater than the conversion price at that time, post-merger CoreComm can also require conversion of the convertible preferred stock.

Conversion at the Option of the Holder. At any time, the holder of the convertible preferred stock may convert the shares into shares of post-merger CoreComm common stock determined by dividing the liquidation value of the shares by a number equal to the conversion price as of such time. Furthermore, in the event of a change of control of

216

post-merger CoreComm, the holders shall, if the then current market price is less than the conversion price, have a one time option, upon not less than 30 days' notice nor more than 60 days' notice, to convert the convertible preferred stock into common stock determined by dividing the liquidation price by the greater of (a) 66.67% of the price of CoreComm common shares at the date of issuance of the convertible preferred stock and (b) the price per common share at which the change of control is occurring.

Determination of the Conversion Price. The conversion price for a conversion made at the option of the holder in the absence of a change of control or at the option of post-merger CoreComm is determined as follows:

- If three-year senior notes are issued to current ATX stockholders:

The conversion price is initially $32.11 per share and is subject to upward adjustment, depending on the aggregate principal amount of three-year senior notes that remain outstanding as of the six-month anniversary of the completion of the ATX merger. At the six-month anniversary, if all of the three-year senior notes remain outstanding, the conversion price will remain at $32.11 per share of post-merger CoreComm common stock. If less than all of the three-year senior notes remain outstanding at the six-month anniversary, the conversion price will increase from $32.11 per share by up to $3.94 per share, pro rata based on the then outstanding portion of the maximum $110 million aggregate principal amount of three-year senior notes that could be issued. If no three-year senior notes are outstanding at the six-month anniversary, the conversion price will be $36.05 per share. The following chart shows, for some assumed outstanding aggregate principal amounts of 3-year senior notes at the six-month anniversary, the conversion price that would apply and the number of shares that would result from a full conversion of the convertible preferred stock at that conversion price.

                                                          NUMBER OF SHARES
    AGGREGATE PRINCIPAL                                    OF COMMON STOCK
AMOUNT OF THREE-YEAR SENIOR     CONVERSION PRICE           INTO WHICH THE
  NOTES OUTSTANDING AS OF         PER SHARE OF            250,000 SHARES OF
       THE SIX-MONTH          POST-MERGER CORECOMM   CONVERTIBLE PREFERRED STOCK
        ANNIVERSARY               COMMON STOCK           WILL BE CONVERTIBLE
---------------------------   --------------------   ---------------------------
   $110.0 million                $32.11                  7,785,737
   $80.0 million                 $33.18                  7,533,627
   $40.0 million                 $34.62                  7,221,828
        None                     $36.05                  6,934,813

- If no three-year senior notes are issued to current ATX stockholders:

The conversion price will initially be the higher of:

(a) $40.328, subject to adjustment under the ATX merger agreement, multiplied by 110%; and

(b) 100% of the volume weighted-average trading price of the CoreComm common shares for the 10 trading day period ending on the trading day prior to the closing date of the ATX merger.

As of the date of this joint proxy statement and prospectus, the initial conversion price determined according to this method would be $44.36, and approximately 5.64

217

million shares of post-merger CoreComm common stock would be issued upon conversion of all of the convertible preferred stock.

Adjustments to Conversion Price. The conversion price is subject to adjustments based on changes in capitalization of post-merger CoreComm common stock such as stock splits, stock dividends, and the like. The conversion price will also be adjusted if, among other things, post-merger CoreComm issues to substantially all holders of post-merger CoreComm common stock rights, options or warrants to subscribe for or purchase shares of post-merger CoreComm common stock at a price below the then current conversion price.

Other Rights. Under the terms of the registration rights agreement to be entered into at the closing of the ATX merger, the initial holders of the convertible preferred stock will have the right in certain circumstances to sell their shares of convertible preferred stock or shares of common stock underlying the convertible preferred stock in underwritten offerings. For further information about these registration rights, please read the section of this joint proxy statement and prospectus entitled "The Merger Agreements -- The Merger Agreement Between CoreComm and ATX -- Related Agreements -- The Registration Rights Agreement."

MORE ABOUT THE COMPANIES

CORECOMM LIMITED

UNAUDITED PRO FORMA FINANCIAL DATA

In May 1999, CoreComm acquired MegsINet Inc. in exchange for cash and common stock and acquired certain assets of USN Communications, Inc. in exchange for cash and warrants to purchase common stock. The unaudited pro forma financial data of CoreComm presented below gives effect to the completed acquisitions of MegsINet and USN and the following proposed transactions:

- the ATX merger only;

- the Voyager merger only; and

- both the ATX merger and the Voyager merger together.

The pro forma financial data is based on CoreComm's historical financial statements and the historical financial statements of MegsINet, USN, ATX and Voyager. CoreComm is treated as the acquiring company for purposes of these pro forma financial data. Certain amounts in these historical financial statements have been reclassified to conform to CoreComm's presentation.

CoreComm will require $40.0 million in cash for the ATX merger and approximately $46.2 million in cash for the Voyager merger based on CoreComm's closing stock price of $11.81 per share on August 10, 2000, as well as the payment of any outstanding indebtedness under the Voyager credit agreement (as of July 14, 2000, the amount was approximately $23.8 million). The unaudited pro forma financial data has been prepared assuming Voyager does not elect to give a termination notice based on the trading price of CoreComm's common shares. CoreComm is evaluating its financing options and anticipates issuing additional debt and/or equity to fund the cash portion of these mergers. We expect post-merger CoreComm to incur negative cash flow from operations at least until post-merger CoreComm establishes an adequate customer base for its services. Post-merger CoreComm will require a significant amount of cash to develop its business, fund its capital commitments and service its indebtedness and other obligations. The unaudited pro forma financial data does not give effect to financing required to fund future operations of the combined companies.

The completed acquisitions have been accounted for using the purchase method of accounting, in which the assets acquired and liabilities assumed have been recorded at their fair values. The proposed mergers have been accounted for using the purchase method of accounting. Accordingly, the assets acquired and liabilities assumed have been recorded at their estimated fair values. We are unaware of events other than those disclosed in the notes to the unaudited pro forma financial data, including the potential adjustment to the Voyager merger exchange ratio, that would require a material change to the preliminary purchase price allocation. However, a final determination of necessary purchase accounting adjustments will be made upon the completion of a study to be undertaken to determine the fair value of certain assets and liabilities, including

219

intangible assets. Assuming CoreComm completes the ATX merger only, the Voyager merger only or both the ATX merger and the Voyager merger, the actual financial position and results of operations will differ, perhaps significantly, from the unaudited pro forma amounts reflected in this joint proxy statement and prospectus because of a variety of factors, including access to additional information, changes in value not currently identified and changes in operating results between the dates of the unaudited pro forma financial data and the dates on which the acquisitions take place.

The unaudited pro forma condensed statements of operations for the six months ended June 30, 2000 and the year ended December 31, 1999 give effect to the completed acquisitions and proposed mergers as if they had been consummated on January 1, 1999. The unaudited pro forma condensed balance sheets at June 30, 2000 give the effect to the proposed mergers as if they had been consummated on June 30, 2000.

ATX provided for bonuses and certain other compensation to its partners. Upon the merger with CoreComm, the compensation of these individuals will either cease or be reduced to be more consistent with compensation levels of other members of management. Approximately $4.2 million and $8.5 million of expense in the six months ended June 30, 2000 and the year ended December 31, 1999, respectively, would not have been incurred had the merger been consummated on January 1, 1999.

The pro forma adjustments are based upon available information and assumptions that we believe were reasonable at the time made. We believe that any variations from the available information and assumptions applied will not have a material effect on the pro forma financial data presented. The unaudited pro forma condensed statements of operations do not purport to present CoreComm's results of operations had the acquisitions occurred on the dates specified, nor are they necessarily indicative of the results of operations that may be achieved in the future. The unaudited pro forma condensed statements of operations do not reflect any adjustments for synergies that we expect to realize. We cannot assure you as to the amounts of, or that any, cost savings or revenue enhancements will be realized.

A significant component of the revenues included in the pro forma results is the historical revenues of USN from January 1, 1999 through the date CoreComm acquired the wireline assets of USN. Although USN quickly developed a large customer list and revenue base in 1997 and 1998, it had difficulties under its previous management providing services, including billing, customer care and other operational areas, and filed for bankruptcy in February 1999. Since the acquisition, CoreComm has been focusing on improving these operations, and has been successful in many areas. However, CoreComm did not actively continue to sell additional lines in these markets because it was not fully satisfied with the quality of the operations. Consequently, and consistent with CoreComm's due diligence, transaction structure and purchase price, revenues associated with the USN assets have declined significantly since the acquisition, and additional declines may continue as customers leave or "churn" off the service. However, CoreComm anticipates that the future operating results derived from the USN assets

220

will improve, although CoreComm has no way of assuring this. Please refer to the section entitled "Special Note Regarding Forward-Looking Statements."

The unaudited pro forma financial statements should be read in conjunction with CoreComm's financial statements and related notes, and with the financial statements and related notes of USN, MegsINet, ATX and Voyager, and the pro forma financial statements of Voyager, incorporated by reference or appearing elsewhere in this joint proxy statement and prospectus.

(1) The ATX share price was determined at the time of the third amendment to the ATX merger agreement on July 31, 2000. The Voyager merger exchange ratio is subject to adjustment if the average trading price prior to closing per common share of CoreComm is greater than $56.97 or less than $41.17. The ratio of cash and stock consideration that Voyager stockholders are entitled to receive is subject to

228

CORECOMM LIMITED

NOTES TO THE UNAUDITED PRO FORMA FINANCIAL DATA -- (CONTINUED)
(IN THOUSANDS)

adjustment if less than 80% of the value of the merger consideration would be in the form of New CoreComm common stock based on the price prior to closing. The Voyager share price is based on the closing price of CoreComm common stock on August 10, 2000 of $11.81.

(2) The Voyager cash consideration was adjusted to represent 20% of the value of the merger consideration.

The number of shares to be issued to ATX and Voyager stockholders may change based on the share price of CoreComm's common stock. If the share price of CoreComm's common stock were to exceed $46.38 and if the shares issued for the ATX merger decrease by 100,000, the total price in accordance with the purchase method of accounting would decrease by $1.4 million, which would be allocated entirely to intangibles, and the related amount of amortization expense would decrease by $0.3 million annually. If the average trading price prior to closing per common share of CoreComm is less than $33.03, and if Voyager does not elect to give a termination notice, for every $1.00 change in the average trading price per common share of CoreComm from the $11.81 assumed herein, the total price in accordance with the purchase method of accounting for the Voyager merger would increase or decrease by approximately $11.5 million, which would be allocated entirely to intangibles, and the related amount of amortization expense would increase or decrease by approximately $2.3 million annually.

The intangible assets arising from the ATX merger and the Voyager merger may include customer lists, other intangibles and goodwill. The amount of each individual intangible is not currently determinable. The amounts of each intangible will be determined based on appraisals and other analyses. The amortization period for each may vary, although it is assumed in Pro Forma Adjustment C below, that 5 years is a representative blended amortization period.

The cash consideration for the Voyager merger is subject to adjustment. The assumed interest rate used for the pro forma data is 12.0%. As of June 30, 2000, CoreComm did not need any additional financing to complete the ATX merger or the Voyager merger.

        outstanding phantom units under its

(1) The ATX share price was determined at the time of the third amendment to the ATX merger agreement on July 31, 2000. The Voyager merger exchange ratio is subject to adjustment if the average trading price prior to closing per common share of CoreComm is greater than $56.97 or less than $41.17. The ratio of cash and stock consideration that Voyager stockholders are entitled to receive is subject to adjustment if less than 80% of the value of the merger consideration would be in the form of New CoreComm common stock based on the price prior to closing. The Voyager share price is based on the closing price of CoreComm common stock on August 10, 2000 of $11.81.

(2) The Voyager cash consideration was adjusted to represent 20% of the value of the merger consideration.

The number of shares to be issued to ATX and Voyager stockholders may change based on the share price of CoreComm's common stock. If the share price of CoreComm's common stock were to exceed $46.38 and if the shares issued for the ATX merger decrease by 100,000, the total price in accordance with the purchase method of accounting would decrease by $1.4 million, which would be allocated entirely to intangibles, and the related amount of amortization expense would decrease by $.03 million annually. If the average trading price prior to closing per common share of CoreComm is less than $33.03, and if Voyager does not elect to give the termination notice, for every $1.00 change in the average trading price per common share of CoreComm from the $11.81 assumed herein, the total price in accordance with the purchase method of accounting for the Voyager merger would increase or decrease by approximately $11.5 million, which would be allocated entirely to intangibles, and the related amount of amortization expense would increase or decrease by approximately $2.3 million annually.

The intangible assets arising from the ATX merger and the Voyager merger may include customer lists, other intangibles and goodwill. The amount of each individual intangible is not currently determinable. The amounts of each intangible will be determined based on appraisals and other analyses. The amortization period for each may vary, although it is

The unaudited pro forma condensed consolidated statement of operations for the year ended December 31, 1999 assumes, that for the acquired entities presented, that the acquisitions in 1999 and 2000 had occurred on January 1, 1999. The unaudited pro forma condensed consolidated statement of operations for the six months ended June 30, 2000 assumes, that for the acquired entities presented, that the acquisition in 2000 had occurred on January 1, 2000. The unaudited pro forma condensed consolidated statements of operations are not necessarily indicative of the results of operations that would actually have occurred if the transactions had been consummated as of January 1, 1999 and January 1, 2000 and are not intended to indicate the expected results for any future period.

VOYAGER.NET, INC.

NOTES TO PRO FORMA CONDENSED CONSOLIDATED
FINANCIAL STATEMENTS (UNAUDITED)

A. Acquired customer bases in the amount of $58.4 million are being amortized over a three-year period beginning January 1, 1999 as if the acquisitions had occurred on that date.

B. The expense related to the issuance of common stock and options has been excluded from the pro forma condensed consolidated statement of operations since it is a non-recurring charge.

C. Voyager.net utilized $51.2 million of its revolving credit facility to complete the acquisitions in 1999 and in 2000. Additional interest expense on the related debt would have been approximately $2.7 million. The assumed interest rate was 8.5% for all periods presented.

VOYAGER.NET, INC.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF

VOYAGER FINANCIAL CONDITION AND RESULTS OF OPERATIONS

RECENT ACCOUNTING INTERPRETATION

On December 3, 1999, the SEC issued Staff Accounting Bulletin 101, Revenue Recognition in Financial Statements. SAB 101 summarizes some of the SEC's interpretations of the application of generally accepted accounting principles to revenue recognition. Revenue recognition under SAB 101 was initially effective for the Company's first quarter 2000 financial statements. However, SAB 101B, which was released June 26, 2000, delayed adoption of SAB 101 until no later than the fourth fiscal quarter 2000. Changes resulting from SAB 101 require that a cumulative effect of such changes for 1999 and prior years be recorded as an adjustment to net income on January 1, 2000 plus adjust the statement of operations for the three months ended in the quarter of adoption.

Although Voyager is still in the process of reviewing SAB 101, it believes that its revenue recognition practices are in substantial compliance with SAB 101 for the year ending December 31, 2000 or that adoption of its provisions would not be material to its annual or quarterly results of operations.

ACQUISITIONS

Voyager's acquisition strategy was designed to leverage its existing network and administrative operations to allow it to enter new markets within the Midwest, as well as to expand its presence in existing markets, and to realize economies of scale. Since December 31, 1999 Voyager has acquired two Internet service provider businesses in the Midwest totaling approximately 12,200 subscribers. Below is a summary of Voyager's completed acquisitions, with the number of subscribers acquired at the respective date of acquisition:

COMPANY                                    DATE        LOCATION      CUSTOMERS
-------                                  ---------    -----------    ---------
Valley Business Equipment..............  Feb. 2000    Oshkosh, WI     11,000
Livingston Online......................  Mar. 2000     Howell, MI      1,200

As a result of the Voyager merger agreement, all acquisition activity has been halted.

The following table sets forth certain consolidated statement of operations data for the three and six months ended June 30, 2000 and 1999. This information should be read in conjunction with Voyager's consolidated financial statements and notes.

Three Months Ended June 30, 2000 Compared to June 30, 1999

Revenues. Total consolidated revenues increased from $10.7 million for the three months ended June 30, 1999 to $18.6 million for the three months ended June 30, 2000, representing an increase of 74%. The revenue growth was primarily driven by the increase in Voyager's customer base from approximately 222,000 at June 30, 1999 to approximately 368,000 at June 30, 2000. The growth in customers was the result of both organic growth and acquisition activity; Voyager experienced internal growth from its effort to provide high quality customer and technical service and support, geographic expansion in its coverage areas and low customer churn rates.

Internet access service costs. Internet access service costs increased from $3.6 million for the three months ended June 30, 1999 to $7.4 million for the three months ended June 30, 2000. Internet access service costs as a percent of revenue increased from 34% for the three months ended June 30, 1999 to 40% for the three months ended June 30, 2000 due to investments in our network infrastructure and call centers. The increase in spending was primarily a result of an increase in customers and their associated network expenses and an increase in billing costs.

246

Sales and marketing. Sales and marketing expenses increased from $1.2 million for the three months ended June 30, 1999 to $2.2 million for the three months ended June 30, 2000. The increase in spending was primarily attributable to the growth in Voyager's customer base and support functions and the expansion of its geographic coverage area. As a percent of revenue, sales and marketing costs remained relatively constant at approximately 11% to 12% for the three months ended June 30, 1999 and 2000.

General and administrative. General and administrative expenses increased from $3.0 million for the three months ended June 30, 1999 to $5.9 million for the three months ended June 30, 2000. The absolute increase in spending was due to the growth of Voyager's business and the administrative functions necessary to support Voyager's growth. As a percentage of revenue, general and administrative costs increased from 28% for the three months ended June 30, 1999 to 32% for the three months ended June 30, 2000 due to additional recurring expenses as a result of Voyager's initial public offering on July 21, 1999. These recurring expenses included public relations, investor relations, and increases in legal, audit, and insurance. Additional expenses are a result of additional staff requirements as a result of Voyager's growth from June 30, 1999 to June 30, 2000.

Depreciation and amortization. Depreciation and amortization expenses increased from $5.0 million for the three months ended June 30, 1999 to $10.2 million for the three months ended June 30, 2000. This increase was primarily a result of the amortization of intangible assets related to acquiring Voyager's customer base since June 30, 1998, as well as increased capital spending for expanded network operations and infrastructure.

Voyager incurred a charge of $1.0 million for the three months ended June 30, 1999 and $25,000 for the three months ended June 30, 2000 related to the issuance of common stock and stock options. The amount of this charge was based on the issuance and grant of common stock and options at purchase and exercise prices below fair market value and a charge to reflect vesting of previously issued common stock or options granted. Voyager believes these charges to be non-recurring in nature because it expects to issue all future shares and stock options at prices that approximate market value. However, some unvested options to purchase common stock will continue to vest over the next four years, which will result in additional compensation expense of approximately $76,000 in periods subsequent to June 30, 2000.

Other expenses, net. Other expenses, net decreased from $1.0 million for the three months ended June 30, 1999 to $0.7 million for the three months ended June 30, 2000. This decrease is the net result of interest income on notes receivable from related parties offset by a higher average balance on Voyager's line-of-credit which was used to fund acquisitions completed during 1999 and 2000.

Net loss. As a result of the above, Voyager reported net loss of $4.5 million, or $0.19 per share applicable to common stockholders, for the three months ended June 30, 1999 as compared to net loss of $7.9 million, or $0.25 per share applicable to common stockholders, for the three months ended June 30, 2000.

247

EBITDA. EBITDA increased from $2.8 million for the three months ended June 30, 1999 to $3.1 million for the three months ended June 30, 2000. EBITDA represents earnings before interest, taxes, depreciation, amortization and non-recurring, non-cash compensation charges. EBITDA is provided because it is a measure commonly used by investors to analyze and compare companies on the basis of operating performance. EBITDA is not a measurement of financial performance under generally accepted accounting principles and should not be construed as a substitute for operating income, net income or cash flows from operating activities for purposes of analyzing our operating performance, financial position and cash flows. EBITDA, as calculated by Voyager, is not necessarily comparable with similarly titled measures for other companies.

Six Months Ended June 30, 2000 Compared to June 30, 1999

Revenues. Total consolidated revenues increased from $19.2 million for the six months ended June 30, 1999 to $36.7 million for the six months ended June 30, 2000, representing an increase of 91%. The revenue growth was primarily driven by the increase in Voyager's customer base from approximately 222,000 at June 30, 1999 to approximately 368,000 at June 30, 2000. The growth in customers was the result of both organic growth and acquisition activity. Voyager experienced internal growth from its effort to provide high quality customer and technical service and support, geographic expansion in its coverage areas and low customer churn rates.

Internet access service costs. Internet access service costs increased from $6.4 million for the six months ended June 30, 1999 to $14.6 million for the three months ended June 30, 2000. Internet access service costs as a percent of revenue increased from 33% for the six months ended June 30, 1999 to 40% for the six months ended June 30, 2000 due to investments in Voyager's network infrastructure and call centers. The increase in spending period over period was primarily a result of an increase in customers and their associated network expenses and an increase in billing costs.

Sales and marketing. Sales and marketing expenses increased from $2.2 million for the six months ended June 30, 1999 to $4.4 million for the six months ended June 30, 2000. The increase in spending was primarily attributable to the growth in Voyager's customer base and support functions and the expansion of its geographic coverage area. As a percent of revenue, sales and marketing costs remained relatively constant at approximately 11% to 12% for the six months ended June 30, 1999 and 2000.

General and administrative. General and administrative expenses increased from $5.5 million for the six months ended June 30, 1999 to $11.9 million for the six months ended June 30, 2000. The absolute increase in spending was due to the growth of Voyager's business and the administrative functions necessary to support its growth. As a percentage of revenue, general and administrative costs increased from 29% for the six months ended June 30, 1999 to 32% for the six months ended June 30, 2000 due to additional recurring expenses as a result of Voyager's initial public offering on July 21, 1999. These recurring expenses included public relations, investor relations, and increases in legal, audit, and insurance. Additional expenses are a result of additional staff

248

requirements as a result of Voyager's growth from June 30, 1999 to June 30, 2000. Headcount for General and Administrative staffing increased 41% from June 30, 1999 to June 30, 2000.

Depreciation and amortization. Depreciation and amortization expenses increased from $8.5 million for the six months ended June 30, 1999 to $18.4 million for the six months ended June 30, 2000. This increase was primarily a result of the amortization of intangible assets related to acquiring Voyager's customer base since June 30, 1998, as well as increased capital spending for expanded network operations and infrastructure.

Compensation charge for issuance of common stock and stock options. Voyager incurred a charge of $2.5 million for the six months ended June 30, 1999 and $50,000 for the six months ended June 30, 2000 related to the issuance of common stock and stock options. The amount of this charge was based on the issuance and grant of common stock and options at purchase and exercise prices below fair market value and a charge to reflect vesting of previously issued common stock or options granted. Voyager believes these charges to be non-recurring in nature because it expects to issue all future shares and stock options at prices that approximate market value. However, some unvested options to purchase common stock will continue to vest over the next four years, which will result in additional compensation expense of approximately $76,000 in periods subsequent to June 30, 2000.

Other expenses, net. Other expenses, net decreased from $1.8 million for the six months ended June 30, 1999 to $1.2 for the six months ended June 30, 2000. This decrease is the net result of interest income on notes receivable from related parties offset by a higher average balance on Voyager's line-of-credit which was used to fund acquisitions completed during 1998, 1999 and 2000.

Net loss. As a result of the above, Voyager reported net loss of $7.8 million, or $0.35 per share applicable to common stockholders, for the six months ended June 30, 1999 as compared to net loss of $13.8 million, or $0.44 per share applicable to common stockholders, for the six months ended June 30, 2000.

EBITDA. EBITDA increased from $5.1 million for the six months ended June 30, 1999 to $5.8 million for the six months ended June 30, 2000. EBITDA represents earnings before interest, taxes, depreciation, amortization and non-recurring, non-cash compensation charges. EBITDA is provided because it is a measure commonly used by investors to analyze and compare companies on the basis of operating performance. EBITDA is not a measurement of financial performance under generally accepted accounting principles and should not be construed as a substitute for operating income, net income or cash flows from operating activities for purposes of analyzing our operating performance, financial position and cash flows. EBITDA, as calculated by Voyager, is not necessarily comparable with similarly titled measures for other companies.

Fiscal Year Ended December 31, 1999 Compared to Fiscal Year Ended December 31, 1998

Revenues. Total consolidated revenues increased from $10.7 million for the twelve months ended December 31, 1998 to $48.5 million for the twelve months ended December 31, 1999, representing an increase of 353.2%. The revenue growth was driven by the increase in Voyager's customer base from approximately 142,000 at December 31, 1998 to approximately 336,000 at December 31, 1999. The growth in customers was primarily the result of Voyager's acquisition activity and strong internal growth from Voyager's effort to provide high quality customer and technical service and support, geographic expansion in Voyager's coverage areas and low customer churn rates.

Internet Access Service Costs. Internet access service costs increased from $3.6 million for the twelve months ended December 31, 1998 to $15.9 million for the twelve months ended December 31, 1999. The increase in absolute spending for the twelve months ended December 31, 1999 was primarily the result of an increase in customers and their associated network expenses and an increase in billing expenses for the increased customer base. Internet access service costs as a percent of revenue decreased from 33.7% for the twelve months ended December 31, 1998 to 32.9% for the twelve months ended December 31, 1999 due to improved telecommunication contracts and economies of scale, partially offset by higher telecommunication costs being incurred by the entities acquired during September and October.

Sales and Marketing. Sales and marketing expenses increased from $2.0 million for the twelve months ended December 31, 1998 to $6.4 million for the twelve months ended December 31, 1999. The increase in spending was attributable to the growth in Voyager's customer base and support functions and the expansion of its geographic coverage area. As a percentage of revenue, sales and marketing expenses decreased from 18.5% for the twelve months ended December 31, 1998 to 13.2% for the twelve months ended December 31, 1999. The decrease in sales and marketing expenses as a percentage of revenue reflects lower average customer acquisition costs, which is primarily attributable to the strong word of mouth and referral programs offered by Voyager.net.

General and Administrative. General and administrative expenses increased from $3.4 million for the twelve months ended December 31, 1998 to $14.2 million for the twelve months ended December 31, 1999. The absolute increase in spending was primarily due to the growth of Voyager's business and the administrative functions necessary to support Voyager's growth. As a percentage of revenue, general and administrative costs decreased from 31.8% for the twelve months ended December 31, 1998 to 29.2% for the twelve months ended December 31, 1999. The decrease on a percentage basis represents leveraging of resources across an increased customer base.

Depreciation and Amortization. Depreciation and amortization expense increased from $3.9 million for the twelve months ended December 31, 1998 to $23.8 million for the twelve months ended December 31, 1999. This increase was primarily the result of the amortization of intangible assets related to acquiring Voyager's customer base since December 31, 1998, as well as increased capital spending for expanded network operations and infrastructure.

250

Compensation Charge for Issuance of Common Stock and Stock Options. Voyager incurred a charge of $4.2 million for the twelve months ended December 31, 1998 which decreased to $2.6 million for the twelve months ended December 31, 1999. These charges were based on the issuance and grant of common stock and options to purchase at exercise prices below fair market value and a charge to reflect vesting of previously issued common stock or options granted. Voyager believes these charges to be non-recurring in nature because Voyager expects to issue all future shares and stock options at prices that approximate market value. However, some unvested options to purchase common stock will continue to vest over the next three years, which will result in additional compensation expense of approximately $111,000 in periods subsequent to December 31, 1999.

Other Income (Expense), Net. Other expense, net increased from $0.9 million for the twelve months ended December 31, 1998 to $1.7 million for the twelve months ended December 31, 1999. This increase is the result of the higher average balance during the first seven months of 1999 on Voyager's line-of-credit which was used to fund acquisitions completed during 1998 and 1999. The line of credit was paid off on July 25, 1999 with proceeds from the initial public offering.

Net Loss. As a result of the above, Voyager reported net loss of $(7.3) million, or $(0.43) per share applicable to common stockholders, for the twelve months ended December 31, 1998 as compared to net loss of $(16.1) million, or $(0.61) per share applicable to common stockholders, for the twelve months ended December 31, 1999.

EBITDA (as defined). EBITDA increased from $1.7 million for the twelve months ended December 31, 1998 to $12.0 million for the twelve months ended December 31, 1999.

Fiscal Year Ended December 31, 1998 Compared to Fiscal Year Ended December 31, 1997

Revenues. Total consolidated revenues increased from $3.5 million for the year ended December 31, 1997 to $10.7 million for the year ended December 31, 1998, representing an increase of 205.7%. The revenue growth was primarily driven by the increase in Voyager's customer base from approximately 17,000 at December 31, 1997 to approximately 142,000 at December 31, 1998. The growth in customers was primarily a result of the seven acquisitions during 1998, which added approximately 100,000 subscribers to our customer base.

Internet Access Service Costs. Internet access service costs increased from $1.3 million for the year ended December 31, 1997 to $3.6 million for the year ended December 31, 1998. Internet access service costs as a percent of revenue decreased from 37.1% for the year ended December 31, 1997 to 33.6% for the year ended December 31, 1998 due to improved telecommunication contracts and economies of scale. The increase in absolute spending for the year ended December 31, 1998 was driven by a significant

251

increase in customers and their associated network expenses and an increase in billing costs.

Sales and Marketing. Sales and marketing expense increased from $1.0 million for the year ended December 31, 1997 to $2.0 million for the year ended December 31, 1998. The increase in absolute spending was a result of the rapid growth of Voyager's operations and the acquisitions completed during 1998. As a percentage of revenue, sales and marketing costs decreased from 28.6% for the year ended December 31, 1997 to 18.7% for the year ended December 31, 1998. The decrease of sales and marketing expenses as a percentage of revenues reflects the efficiencies of Voyager's marketing programs over a larger customer base.

General and Administrative. General and administrative expenses increased from $1.5 million for the year ended December 31, 1997 to $3.4 million for the year ended December 31, 1998. The absolute increase in spending was due to the increase in support functions and basic infrastructure necessary to support the expansion of Voyager's business and the acquisition activity. As a percentage of revenue, general and administrative expenses decreased from 42.9% for the year ended December 31, 1997 to 31.8% for the year ended December 31, 1998. The decrease on a percentage basis represents efficiencies achieved through the integration of acquired businesses and leveraging resources across an increased customer base.

Depreciation and Amortization. Depreciation and amortization expense increased from $394,000 for the year ended December 31, 1997 to $3.9 million for the year ended December 31, 1998. This increase was a result of the amortization of intangible assets related to acquiring Voyager's customer base since December 31, 1997, as well as increased capital spending for expanded network operations and infrastructure.

Compensation Charge for Issuance of Common Stock and Stock Options. Voyager incurred a charge of $4.2 million for the year ended December 31, 1998 related to the issuance of common stock and stock options. The amount of this charge was based on the issuance and grant of common stock and options at purchase and exercise prices below fair market value.

Other Income (Expense), Net. Other expenses, net increased from $62,000 for the year ended December 31, 1997 to $0.9 million for the year ended December 31, 1998. This increase is the result of the higher average balance on Voyager's $40.0 million line-of-credit which was used to fund acquisitions completed during 1998.

Net (Loss). As a result of the above, Voyager reported a net loss of $(0.8) million, or $(0.10) per share, applicable to common stockholders, for the year ended December 31, 1997 as compared to a net loss of $(7.3) million, or $(0.43) per share applicable to common stockholders, for the year ended December 31, 1998.

EBITDA. EBITDA increased from ($364,000) for the year ended December 31, 1997 to $1.7 million for the year ended December 31, 1998. As a percentage of revenues, EBITDA increased from (10.5%) for the year ended December 31, 1997 to 16.1% for the year ended December 31, 1998.

252

LIQUIDITY AND CAPITAL RESOURCES.

Voyager's principal capital and liquidity needs historically have related to funding the cash portion of acquisitions, sales and marketing activities, the development and expansion of network infrastructure, the establishment of customer service and support operations and general working capital needs. Voyager's capital needs have historically been met through receipts from its prepaid customer base and additional capital from outside sources, including vendor capital leases, and the use of a $60.0 million revolving credit facility with a bank group led by Fleet National Bank.

On July 21, 1999, Voyager completed its initial public offering in which it raised net proceeds of approximately $99.5 million. Upon closing of the offering, $60.6 million of senior bank debt and accrued interest and fees were repaid, $8.8 million of preferred stock and cumulative dividends were redeemed, and $2.3 million of subordinated notes and accrued interest were repaid. Since the initial public offering, Voyager has used all of the remaining proceeds for general corporate purposes, acquisitions and capital expenditures.

Net cash provided by operating activities was $1.7 million for the six months ended June 30, 2000, compared to net cash provided by operating activities of $4.6 million for the six months ended June 30, 1999. The primary sources of cash from operating activities for the six months ended June 30, 2000 were $18.0 million in depreciation and amortization. These sources were partially offset by a $13.8 million net loss and a $1.1 million increase in deferred revenue.

Net cash used in investing activities was $10.1 million for the six months ended June 30, 2000, compared to net cash used in investing activities of $26.2 million for the six months ended June 30, 1999. Net cash provided from investing activities for the six months ended June 30, 2000 consisted of $5.3 million to acquire two Internet service provider businesses and $4.8 million for the purchase of capital equipment. Cash used in investing activities for the six months ended June 30, 1999 related to acquisition activity and the purchase of capital equipment.

Net cash provided by financing activities was $2.7 million for the six months ended June 30, 2000, compared to net cash provided by financing activities of $24.0 million for the six months ended June 30, 1999. The primary sources of cash from financing activities for the six months ended June 30, 2000 was the use of proceeds from Voyager's revolving credit facility and payments on capital leases.

Voyager believes that available cash on hand, amounts available under the credit facility, additional capital financing arrangements and cash flow from operations will be sufficient to meet Voyager's capital requirements for the next twelve months. Voyager's capital requirements depend on numerous factors including market acceptance of its services, its ability to maintain and expand its customer base, the rate of expansion of its infrastructure, the roll out of its DSL plan, which is expected to be available in selected Midwest cities at the end of the third quarter 2000 and other factors.

253

YEAR 2000 COMPLIANCE.

Voyager relies on third party telecommunications and information systems equipment and software that may not be Year 2000 compliant to provide its services. Voyager's efforts to address Year 2000 issues prior to January 1, 2000, included conducting an audit of its own systems and of its third-party suppliers as to assessment. Voyager developed and implemented a remediation plan with respect to third-party software, computer technology and services that may have failed to be Year 2000 compliant. Costs incurred to date related to Year 2000 issues have not been material, nor does it expect to incur additional material costs related to Year 2000 issues.

FORWARD-LOOKING STATEMENTS

This Management's Discussion and Analysis of Financial Condition and Results of Operations contains "forward-looking statements" within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934 that are subject to future events, risk and uncertainties that could cause actual results to differ materially from those expressed or implied. These statements can sometimes be identified by use of forward-looking words such as "may," "will," "anticipate," "estimate," "expect," or "intend." Important factors that either individually or in the aggregate could cause actual results to differ materially from those expressed include, without limitation, (1) the risk that the merger of Voyager and CoreComm will not be consummated, (2) Voyager's ability to provide superior customer care, (3) the success of its growth strategy, (4) its ability to integrate acquisitions successfully, (5) increased competition from regional and national Internet service providers, Voyager's ability to rollout its DSL strategy and (6) general economic conditions.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Voyager believes its exposure to market rate fluctuations on its investments is nominal due to the short-term nature of these investments. Voyager has no material future earnings or cash flow exposures with respect to its capital leases, which are all at fixed rates. To the extent it has borrowings outstanding under its credit facility, Voyager would have market risk relating to those amounts because the interest rates under the credit facility are variable. At present, Voyager has no plans to enter into any hedging arrangements with respect to those borrowings.

ATX

MANAGEMENT'S DISCUSSION AND ANALYSIS OF
ATX FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis should be read in conjunction with the unaudited condensed financial statements and notes thereto of ATX included herein as well as the combined financial statements and notes included in this joint proxy statement and prospectus. This information is not necessarily indicative of future operating results. Except for the historical information contained below, the matters discussed in this section are forward-looking statements that involve a number of risks and uncertainties, including those described in "Risk Factors." ATX's actual liquidity needs, capital resources and operating results may differ materially from the discussion set forth below in these forward-looking statements.

GENERAL

ATX operates a switch and facilities-based network that provides integrated voice and broadband data services including long distance, local and network services, Internet access and Web consulting, development and hosting. ATX was formed in 1985 and began as a switch and facilities-based provider of long distance services. Over time, ATX expanded its product offerings to meet the needs of its customers.

ATX has diversified its revenues by broadening its services in becoming a competitive local exchange carrier, Internet service provider and offering web based hosting and networking services to new and existing customers. ATX is in the process of transitioning local customers to its switched-based facility which ATX believes will increase gross profit margins by significantly reducing local carrier costs.

Until it was organized on February 9, 2000 as a corporation, ATX conducted its business operations through two limited partnerships, ATX Telecommunications Services, Ltd. and Global Telecom Services, Ltd. Upon the incorporation of ATX, Inc., ATX was subject to federal and state income taxation. ATX did not provide for an income tax benefit for the six months ended June 30, 2000 based on the uncertainty of future earnings and profits.

Three Months Ended June 30, 2000 as Compared to Three Months Ended June 30, 1999

Revenues

Revenues increased by $6.8 million or 20.4% to $40.3 million for the three months ended June 30, 2000 from $33.5 million for the same period in the prior year. The increase was primarily due to the development of local, Internet and network integration service revenue. Local exchange revenues increased approximately $4.3 million or 82.5% compared to the same period in the prior year. Network and wireless revenues increased approximately $2.3 million or 52.3% compared to the same period in the prior year.

Gross Profit

Gross profit decreased $1.8 million or 14.6% to $10.7 million for the three months ended June 30, 2000 from $12.5 million for the same period in the prior year. Gross profit as a percentage of revenue decreased 10.9% for the three months ended June 30, 2000 compared with the same period in the prior year as a result of additional costs associated with the transitioning of local exchange customers to ATX's network from a resale environment. Such transition costs include the build-out of co-locations and increased carrier costs to transition customers from a resale environment to ATX's network.

Selling, General and Administrative Expenses

Selling, general and administrative expenses increased $3.0 million to $15.9 million for the three months ended June 30, 2000 from $12.9 million for the same period in the

256

prior year because of the expansion of the sales force and infrastructure in anticipation of providing additional local exchange service and other products.

Year Ended December 31, 1999 as Compared to Year Ended December 31, 1998

Revenues

Revenues increased by $21.4 million to $135.0 million in fiscal year 1999 from $113.7 million in fiscal year 1998, representing an 18.8% increase. The increase was primarily due to the increase in long distance traffic and the development of local, Internet and network integration service revenues. There was also an increase in long distance traffic. The components of revenues include the diversification of services related to local exchange service, network and Internet and wireless based revenues. Local exchange revenues increased $14.4 million, representing an increase of 215.3% from fiscal year 1998. Network and wireless services revenues increased $4.7 million, representing an increase of 33.3% from fiscal 1998. Long distance revenues increased $2.3 million, representing an increase of 2.5% from fiscal year 1998.

Gross Profit

Gross profit increased to $49.5 million in fiscal year 1999 from $45.2 in fiscal year 1998, representing an increase of 9.5%. Gross profit as a percentage of revenues decreased 3.1% in fiscal year 1999 from 39.8% to 36.7% in fiscal year 1998, primarily as a result of ATX's lower gross margin for providing local exchange service in a resale environment.

258

Selling, General and Administrative Expenses

Selling, general and administrative expenses increased to $51.2 million in fiscal year 1999 from $43.3 million in fiscal year 1998 but decreased as a percentage of revenues to 37.9% in fiscal year 1999 from 38.1% in fiscal year 1998. Selling, general and administrative expenses, excluding partners' salaries and bonuses, increased $7.9 million relating to the expansion of the sales force and infrastructure in anticipation of providing additional local exchange service and other products. Salaries and related expenses excluding partners' salaries and bonuses are the most significant component of selling, general and administrative expenses and decreased as a percentage of selling, general and administrative expenses to 46.9% in fiscal year 1999 from 50.4% in fiscal year 1998. Selling, general and administrative expenses, excluding partners' salaries and bonuses, represented 31.0% and 29.9% of revenues for fiscal year 1999 and fiscal year 1998, respectively.

Net Loss

As a result of the expansion of the sales force and customer service in anticipation of future local exchange service and new product growth and Year 2000 expenditures, ATX incurred a net loss of $1.6 million in fiscal year 1999 compared with net income of $2.1 million in fiscal year 1998.

Year Ended December 31, 1998 as Compared to Year Ended December 31, 1997

Revenues

Revenues increased $21.1 million to $113.7 million in fiscal year 1998 from $92.6 million in fiscal year 1997, representing an increase of 22.8%. The increase was primarily due to the development of new products, including local exchange service and Internet based revenues. Local exchange service, network and Internet and wireless based revenues increased $11.5 million, representing a 123.6% increase from fiscal year 1997. Long distance revenues increased $9.6 million, representing a 11.5% increase from fiscal year 1997.

Gross Profit

Gross profit increased to $45.2 million in 1998 from $39.8 in 1997, representing an increase of 13.6%. Gross profit as a percentage of revenues decreased 3.2% to 39.8% in 1998 from 43.0% in 1997 primarily as a result of local carrier costs that resulted in lower margins in 1998 compared with 1997.

Selling, General and Administrative Expenses

Selling, general and administrative expenses increased to $43.3 million in fiscal year 1998 from $26.4 million in fiscal year 1997 and increased as a percentage of revenues to 38.1% in fiscal year 1998 from 28.5% in fiscal year 1997. Salaries and related expenses, excluding partners' salaries and bonuses, are the most significant component of selling, general and administrative expenses and decreased to 50.4% of selling, general and administrative expenses in fiscal year 1998 from 51.4% in fiscal year 1997. In fiscal year 1998, selling, general and administrative expenses included partners bonuses of $8.0 million compared to $0 in fiscal year 1997. Selling, general and administrative expenses,

259

excluding partners' bonuses and salaries, increased $8.9 million relating to the expansion of the sales force and infrastructure in anticipation of providing local exchange service and other products. Selling, general and administrative expenses, excluding partners' bonuses and salaries, represented 29.9% and 27.1% of revenues for fiscal year 1999 and fiscal year 1998, respectively. Additionally, ATX instituted a phantom unit plan for its employees in fiscal year 1998 that resulted in a non-cash charge to selling, general and administrative expenses of $1.8 million in fiscal year 1998.

Net Income

As a result of the partners' bonuses of $8 million and increased cost of revenues due to expansion of the sales force and costs related to increased customer service in anticipation of future local exchange service growth, ATX's net income decreased to $2.1 million in fiscal year 1998 compared to net income of $13.6 million in fiscal year 1997.

LIQUIDITY AND CAPITAL RESOURCES

ATX intends to continue its growth and its coverage of products and services in the northeastern region of the United States. ATX plans to expand its local exchange services through the build out of co-locations and purchases of network equipment. ATX has historically funded expansion into new markets, offering of new products and services and capital acquisitions through operations. If the ATX merger is not consummated, ATX may seek to raise additional funds through short term borrowings or private investment or raise capital in the public markets to fund those estimated capital expenditures and expansion of Competitive Local Exchange Service including the build out of co-locations and customer transition costs from a resale environment to its network. There can be no assurance that such funding will be available on acceptable terms and conditions which may cause the delay of certain of ATX's development plans.

ATX believes that its future cash flows from operations will be sufficient to fund its growth and future capital expenditures for the next 12 months including the additional costs relating to the expansion of Completive Local Exchange Service and its effect on future operations and earnings. ATX's expectations of future capital requirements and cash flows are based on current estimates and such estimates include the future increase in overall operating gross margins upon transitioning local exchange customers to its network. Based on the terms and conditions of the ATX merger agreement, ATX cannot be sure that actual costs or the timing and scope of the expenditures will be consistent with current estimates.

Cash and cash equivalents increased $300,000 at June 30, 2000 to $3.5 million from $3.2 million as of December 31, 1999. The increase is primarily attributable to cash provided by operation activities of $4.7 million, advances from related parties and capital contributions of $1.9 million, net of capital expenditures of $6.3 million.

INFLATION

ATX management does not believe that its business is impacted by inflation to a significantly different extent than the general economy.

ATX is not currently subject to the reporting requirements of the Securities Exchange Act of 1934, and accordingly does not file any reports, proxy statements or other information with the SEC. Upon the filing of the registration statement on Form S-4 and the completion of the ATX merger and the Voyager merger, however, post-merger CoreComm will become subject to the Exchange Act and will be required to file the applicable reports, proxy statements and other information with the SEC. You will be able to obtain copies of these filed documents from post-merger CoreComm, and you will be able to review and copy these documents in the manner described above.

This joint proxy statement and prospectus will be part of a registration statement on Form S-4 to be filed with the SEC under the Securities Act of 1933 by the surviving company in the ATX merger, which will be named CoreComm Limited, to register the issuance of its common stock to the current shareholders of CoreComm and the current stockholders of Voyager. Those shares will be held by public stockholders only if the ATX merger is approved and completed. This joint proxy statement and prospectus will also be part of a registration statement on Form S-4 to be filed with the SEC under the Securities Act by the Delaware corporation into which CoreComm will merge in the domestication merger, to register the issuance of its common stock to the current shareholders of CoreComm and the current stockholders of Voyager in connection with the Voyager merger. Those shares will be held by public stockholders only if the Voyager merger is approved and completed but the ATX merger is not.

This joint proxy statement and prospectus, which will constitute a part of each registration statement, does not contain all the information that will be set forth in the

262

registration statements. Some items of information will be contained in exhibits to the registration statements, as permitted by the rules and regulations of the SEC. Statements made in this joint proxy statement and prospectus as to the content of any contract, agreement or other document referred to are not necessarily complete. With respect to each of those contracts, agreements or other documents to be filed or incorporated by reference as an exhibit to the relevant registration statement, you should refer to the corresponding exhibit, when it is filed, for a more complete description of the matter involved and read all statements in this joint proxy statement and prospectus in light of that exhibit.

Because the completion of each of the Voyager merger and the ATX merger is not conditioned on the completion of the other, until the required shareholder votes occur and the mergers that are approved are completed, it is not possible to know which company will survive the mergers as the ultimate parent company. Therefore, registration statements for the surviving company resulting from completion of the ATX merger and the surviving company resulting from the completion of only the Voyager merger and not the ATX merger will be filed. However, the stock of only one company -- the ultimate parent company, depending on which mergers occur -- will be held and publicly traded.

MATERIAL UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

The following is a discussion of the material United States federal income tax consequences of the Voyager merger, the ATX merger and the domestication merger. The following discussion and the United States federal income tax opinions referred to below are based on and subject to the Internal Revenue Code of 1986, as amended, the regulations promulgated thereunder, existing administrative interpretations and court decisions and related laws, all of which are subject to change, possibly with retroactive effect, and based on assumptions, limitations, representations and covenants, including those contained in the representation letters of CoreComm, ATX and Voyager referred to below. This discussion does not address all aspects of United States federal income taxation that may be important to you in light of your particular circumstances or if you are subject to special rules, such as rules relating to:

- shareholders who are not citizens or residents of the United States

- financial institutions

- tax-exempt organizations

- insurance companies

- dealers in securities

- shareholders who acquired their shares of CoreComm or Voyager common stock through the exercise of options or similar derivative securities or otherwise as compensation

- shareholders who hold their shares of CoreComm or Voyager common stock as part of a straddle or conversion transaction.

This discussion assumes that you hold your CoreComm common stock or Voyager common stock as a capital asset within the meaning of Section 1221 of the Internal Revenue Code.

None of CoreComm, ATX or Voyager has requested or intends to request a ruling from the Internal Revenue Service regarding the tax consequences of any of the transactions with respect to CoreComm, ATX, Voyager or the shareholders of CoreComm, ATX or Voyager. Accordingly, no assurance can be given that the statements set forth in this discussion, which do not bind the Internal Revenue Service or the courts, will not be challenged by the Internal Revenue Service or sustained by the courts if so challenged.

Paul, Weiss, Rifkind, Wharton & Garrison, counsel to CoreComm, has delivered an opinion that the description of the federal income tax consequences to holders of CoreComm common shares contained under the heading "Treatment of CoreComm Shareholders" below and under the heading "Reporting Requirements" below correctly sets forth the material federal income tax consequences for CoreComm shareholders. Goodwin, Procter & Hoar LLP, counsel to Voyager, has delivered an opinion that the description of the federal income tax consequences to holders of Voyager Common Stock contained under the heading "Treatment of Voyager Shareholders" below and under the

264

heading "Reporting Requirements" below correctly sets the forth material federal income tax consequences for Voyager shareholders. Those opinions and the opinions set forth in the following paragraph are based on, among other things, representation letters provided to counsel by CoreComm, ATX and Voyager that will be confirmed by CoreComm, ATX and Voyager prior to the closing of the respective mergers.

Based upon, among other things, the representation letters referred to in the preceding paragraph, (a) it is the opinion of Paul, Weiss, Rifkind, Wharton & Garrison that the domestication merger constitutes for federal income tax purposes a reorganization described in Section 368(a) of the Internal Revenue Code; (b) it is the opinion of Paul, Weiss, Rifkind, Wharton & Garrison that the ATX merger constitutes for federal income tax purposes a reorganization described in Section 368(a) of the Internal Revenue Code and/or an exchange described in Section 351 of the Internal Revenue Code; (c) it is the opinion of Paul, Weiss, Rifkind, Wharton & Garrison that the Voyager merger constitutes for federal income tax purposes a reorganization within the meaning of Section 368(a) of the Internal Revenue Code and/or an exchange described in Section 351 of the Internal Revenue Code and (d) it is the opinion of Goodwin, Procter & Hoar LLP that the Voyager merger constitutes for federal income tax purposes a reorganization described in Section 368(a) of the Internal Revenue Code and/or an exchange described in Section 351 of the Internal Revenue Code. It is a condition to the obligation of CoreComm to complete the ATX merger that CoreComm shall have received the written opinion of its counsel to the effect set forth in clause (b) of the preceding sentence, and that such opinion shall not have been withdrawn. It is a condition to the respective obligations of CoreComm and Voyager to complete the Voyager merger that each shall have received the written opinion of its respective counsel to the effect set forth in clauses (c) and (d) of the preceding sentence, and that such opinion shall not have been withdrawn.

TREATMENT OF CORECOMM SHAREHOLDERS

Consequences of the Domestication Merger to CoreComm Shareholders.

A holder of CoreComm common shares who, under the domestication merger, exchanges CoreComm common shares for common stock of the newly-formed wholly- owned subsidiary of CoreComm will not recognize gain or loss as a result of this exchange, provided that CoreComm does not have any earnings and profits at the time of the domestication merger and further provided that, in the case of holders of CoreComm common shares that own less than 10% of CoreComm, such holder files an election with the Internal Revenue Service to include earnings and profits in lieu of recognizing gain. CoreComm believes it will not have any earnings and profits at the time of the domestication merger. The tax basis of the common shares received by the holder will be equal to the tax basis of the common shares surrendered, and the holding period of the common shares will include the holding period of the CoreComm common shares surrendered.

265

Consequences of the ATX Merger, If the Voyager Merger Does Not Occur, and Consequences of the ATX Merger and the Voyager Merger, If Both Occur, to CoreComm Shareholders Who Have Become Stockholders of the Newly-Formed Wholly-Owned Subsidiary of CoreComm Under the Domestication Merger

If the ATX merger occurs and the Voyager merger does not occur or if both the ATX merger and the Voyager merger occur, a holder of common stock received under the domestication merger who exchanges such common stock for ATX common stock under the ATX merger will not recognize gain or loss as a result of such exchange. The tax basis of the post-merger CoreComm common stock received by the holder will be equal to the tax basis of the domesticated CoreComm Merger Sub, Inc. common stock surrendered, and the holding period of the post-merger CoreComm common stock will include the holding period of the common stock of CoreComm Merger Sub, Inc. surrendered.

Consequences of the Voyager Merger, If the ATX Merger Does Not Occur, to CoreComm Shareholders Who Have Become Stockholders of the Newly-Formed Wholly-Owned Subsidiary of CoreComm Under the Domestication Merger

If the Voyager merger occurs and the ATX merger does not occur, a holder of domesticated CoreComm Merger Sub, Inc. common stock received under the domestication merger will not recognize gain or loss as a result of the Voyager merger.

TREATMENT OF VOYAGER STOCKHOLDERS

A holder of Voyager stock will recognize gain as a result of the Voyager merger equal to the lesser of the amount of cash received or the amount of gain realized. The holder's tax basis in the common stock of post-merger CoreComm received in the Voyager merger will be the holder's tax basis in the Voyager stock surrendered, decreased by the amount of cash received and increased by the amount of gain recognized, and the holder's holding period in the common stock of CoreComm (or its successor) received in the Voyager merger will include the holding period in the Voyager stock surrendered.

TAX IMPLICATIONS TO CORECOMM, ATX AND VOYAGER

CoreComm, ATX and Voyager will not recognize gain or loss for United States federal income tax purposes as a result of the domestication merger, the ATX merger and/or the Voyager merger.

REPORTING REQUIREMENTS

If you participate in an exchange of stock under the domestication merger, the ATX merger and/or the Voyager merger, you will be required to retain records and attach a statement to your tax returns for the taxable year in which the mergers are completed that contains facts relating to the exchange of stock, including the cost or other basis of stock surrendered in the merger(s) and the amount of stock received under the merger(s). All stockholders are urged to consult their own tax advisors to determine the

266

specific information that they may need to retain and/or file with the Internal Revenue Service.

This foregoing discussion is not intended to be a complete analysis or description of all potential United States federal income tax consequences or any other consequences of the merger(s). In addition, this discussion does not address tax consequences that may vary with, or are contingent on, your individual circumstances. Moreover, this discussion does not address any non-income tax or any foreign, state or local tax consequences of the merger(s). Accordingly, you are strongly urged to consult with your tax advisor to determine the particular United States federal, state, local or foreign income or other tax consequences to you of the mergers.

These condensed consolidated financial statements of Voyager.net, Inc. and its subsidiaries (the "Company") for the three and six months ended June 30, 2000 and 1999 and the related footnote information are unaudited and have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission. These financial statements included herein should be read in conjunction with the Company's audited consolidated financial statements and the related notes to the consolidated financial statements as of and for the year ended December 31, 1999, which are included in the Company's Form 10-K filed with the Securities and Exchange Commission and dated March 31, 2000. In management's opinion, the accompanying unaudited financial statements contain all adjustments (consisting of normal, recurring adjustments) which management considers necessary to present the consolidated financial position of the Company at June 30, 2000 and the results of its operations and cash flows for the three and six months ended June 30, 2000 and 1999. Certain information and footnote disclosures normally included in the financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted pursuant to such rules and regulations. The results of operations for the three and six months ended June 30, 2000 are not necessarily indicative of the results of operations expected for the year ended December 31, 2000.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

The pro forma results above include amortization of intangibles and interest expense on debt assumed issued to finance the acquisitions. The pro forma results are not necessarily indicative of what actually would have occurred if the acquisitions had been completed as of the beginning of each of the fiscal periods presented, nor are they necessarily indicative of future consolidated results.

3. DEBT:

The Company has a revolving available credit facility with a bank group in the amount of $60 million, with the option to extend to $70 million, on similar terms and conditions. The credit facility matures on June 30, 2005. The revolving credit facility agreement allows the Company to elect an interest rate as of any borrowing date based on either the (1) prime rate, or (2) LIBOR, plus a margin ranging from 0.5% to 2.75% depending on the ratio of funded debt to EBITDA. The elected rate as of June 30, 2000 is approximately 8.70%. Automatic and permanent reductions of the maximum commitments begin June 30, 2001 and continue until maturity.

4. EARNINGS PER SHARE:

The impact of dilutive shares is not significant. Net loss per share is computed using the weighted average number of common shares outstanding during the period. Inclusion of common share equivalents of 3,983,847 would be antidilutive and have been excluded from per share calculations.

5. SUPPLEMENTAL DISCLOSURE OF CASH FLOW INFORMATION:

The following is the supplemental cash flow information for all periods presented:

                                                                SIX MONTHS ENDED

Issuance of compensatory common stock and options........  $    50,000    $  1,044,000

6. STOCK-BASED COMPENSATION PLAN:

During the six months ended June 30, 2000, the Company granted 545,381 options to purchase common stock to certain members of management, employees and non-

F-7

VOYAGER.NET, INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

employees. At the grant date, all of the options granted vest in four equal annual installments beginning January 6, 2001. The exercise price for these options was not less than the fair market value of the Company's common stock on the grant date. Therefore, no additional compensation expense has been recognized in the six months ended June 30, 2000 for these options.

During the six months ended June 30, 2000, the Company recognized compensation expense of $50,000 relating to options granted prior to January 1, 2000.

7. RECENT ACCOUNTING INTERPRETATION:

On December 3, 1999, the Securities and Exchange Commission ("SEC") issued Staff Accounting Bulletin 101 ("SAB 101"), Revenue Recognition in Financial Statements. SAB 101 summarizes some of the SEC's interpretations of the application of generally accepted accounting principles to revenue recognition. Revenue recognition under SAB 101 was initially effective for the Company's first quarter 2000 financial statements. However, SAB 101B, which was released June 26, 2000, delayed adoption of SAB 101 until no later than the fourth fiscal quarter 2000. Changes resulting from SAB 101 require that a cumulative effect of such changes for 1999 and prior years be recorded as an adjustment to net income on January 1, 2000 plus adjust the statement of operations for the three months ended in the quarter of adoption.

Although the Company is still in the process of reviewing SAB 101, it believes that its revenue recognition practices are in substantial compliance with SAB 101 for the year ending December 31, 2000 or that adoption of its provisions would not be material to its annual or quarterly results of operations.

8. MERGER AGREEMENT:

On March 12, 2000, the Company entered into an agreement to merge with CoreComm Limited is a stock and cash transaction. The transaction is subject to stockholder approval, certain regulatory approvals and other conditions.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Organization and basis of presentation

Voyager.net, Inc. (the "Company ") owns 100% of Voyager Information Networks, Inc., which was incorporated in the State of Michigan in 1994. Voyager.net was incorporated in 1998 in the State of Delaware under the name Voyager Holdings, Inc. The Company's name was changed to Voyager.net, Inc. on April 29, 1999. The Company provides full service access to the Internet for corporate and residential users in Michigan, Illinois, Indiana, Minnesota, Ohio and Wisconsin.

Revenue recognition

The Company recognizes revenue for dial-up Internet access services, dedicated Internet access services and value-added Web services when the services are provided. Dial-up and dedicated Internet access service plans range from one month to one year. Value-added Web services are sold on a monthly basis. Advance collections relating to future access services are recorded as deferred revenue and recognized as revenue when earned.

Cash equivalents

The Company considers all highly liquid investments purchased with an initial maturity of three months or less to be cash equivalents.

Property and equipment

Property and equipment are stated at cost and depreciated over their estimated useful lives using the straight-line method. Equipment acquired under capital leases is depreciated over the related lease terms or the estimated productive useful lives, depending on the criteria met in determining the qualification as a capital lease. Costs of repair and maintenance are charged to expense as incurred.

Intangible assets

Intangible assets consist primarily of the cost of the acquired customer base. The acquired customer base is amortized using the straight-line method over 3 years based on the estimated customer churn rate. Bank financing fees, included in intangible assets, are being amortized on a straight-line basis over the term of the related debt. Other intangible assets are amortized over a 10 year period. Impairments, if any, are measured based upon discounted cash flow analyses and are recognized in operating results in the period in which the impairment in value is determined.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

Advertising costs

Advertising costs are expensed as incurred. Advertising expense of approximately $372,000, $185,000 and $1,174,000 was charged to operations in 1997, 1998 and 1999, respectively.

Financial instruments

The Company's financial instruments, as defined by Statement of Financial Accounting Standards ("SFAS") No. 107 "Disclosures About Fair Value of Financial Instruments," consist of cash, notes payable and long-term debt. The Company's estimate of the fair value of these financial instruments approximates their carrying amounts at December 31, 1998 and 1999.

Use of estimates

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Income taxes

A current tax liability or asset is recognized for the estimated taxes payable or refundable on tax returns for the year. Deferred tax liabilities or assets are recognized for the estimated future tax effects of temporary differences between financial and tax accounting.

10 years. During 1998, the Company issued 2,232,000 shares of restricted common stock to certain members of management for a nominal amount; 496,000 of which were subject to certain vesting provisions at December 31, 1998 through October 2002. During 1999, the Company issued an aggregate of 1,240,000 shares of restricted common stock at $4.84 per share to a member of management and the Chairman of the Board. Certain of these shares were subject to vesting through 2003. Prior to the Company's initial public offering, all shares of the unvested restricted common stock were accelerated and became 100% fully vested. The weighted average fair value at issuance for the restricted common stock and options were $1.77 and $6.16 per share at December 31, 1998 and 1999, respectively. Accordingly, the Company recorded compensation expense of $4,218,407 and $2,563,311 for the years ended December 31, 1998 and 1999, respectively.

Under SFAS No. 123, "Accounting for Stock-Based Compensation" (SFAS 123), compensation cost is measured at the grant date based on the value of the award and is recognized over the service (or vesting) period. Under SFAS 123, the Company's net loss and loss per share for the years ended December 31, 1998 and 1999 would have been adjusted to the pro forma amounts indicated in the following table:

Net loss per share is computed using the weighted average number of common shares outstanding during the period. Inclusion of common share equivalents would be anti-dilutive and have been excluded from the per share calculations for 1999. The impact of dilutive shares was not significant for 1997 and 1998.

ATX TELECOMMUNICATIONS SERVICES, INC.

NOTES TO UNAUDITED FINANCIAL STATEMENTS

1. ORGANIZATION AND BUSINESS

ATX Telecommunication Services, Inc. ("ATX, Inc." or "the Company") was organized in the state of Delaware on February 9, 2000 upon the consent of the former partners of ATX Telecommunications LP ("ATX") and Global Telecom LP ("Global"). The financial position of the Company as of June 30, 2000 included the net assets contributed by the former partnerships of ATX and Global to ATX, Inc. on February 9, 2000 at their historical costs basis. For financial reporting purposes, the results of operations for the Six Months ended June 30, 2000 include the results of operations of the former partnerships of ATX and Global. These partnerships were terminated on February 9, 2000 upon their merger into ATX, Inc. ATX, Inc. was capitalized with 10,000 shares of common stock at $.01 par value. Upon the merger, 1,000 shares of common stock was issued to the former partners of ATX and Global.

Upon the merger into ATX, Inc., distributions were made to certain former partners of ATX to satisfy their loans and advances.

The Company is a single-source provider of voice and data services offering a full range of telecommunications services, including long distance, local, data, private line, cellular, PC-based billing, prepaid calling, paging, Internet access and World Wide Web consulting, development and hosting.

The ATX Shareholders Agreement and former Partnership Agreements provided for bonuses to certain executives totaling $8,000,000 per year. The Company has recorded $4,000,000 of compensation expense for these bonuses included in selling, general and administrative expenses for the Six Months ended June 30, 2000 and June 30, 1999. These bonuses will be eliminated upon the merger agreement as discussed on Note 2.

2. PLAN OF RECAPITALIZATION AND MERGER

On April 9, 2000, ATX, Inc. and its stockholders ("ATX Stockholders") entered into a plan of recapitalization and merger ("Merger Agreement") with CoreComm Limited ("CoreComm"). Under the terms of the merger agreement, as amended, the ATX stockholders will exchange their issued and outstanding common stock for the following aggregate consideration: (i) approximately 12.4 million shares of CoreComm common stock; (ii) $250 million of CoreComm's 3% senior convertible preferred stock and (iii) $150 million in cash from CoreComm. Such amounts may be subject to adjustments as defined in the merger agreement. In the event CoreComm has not completed a debt or equity financing prior to the closing date, CoreComm may elect to issue short term notes of $110 million and reduce the cash consideration by such amount. The Merger Agreement is subject to regulatory and CoreComm shareholder approval, amongst other conditions.

3. BASIS OF PRESENTATION

In the opinion of management, all adjustments which have been made are necessary to present fairly the financial position of the Company as of June 30, 2000 and 1999 and the results of operations for the six month periods ended June 30, 2000 and 1999. The

F-33

ATX TELECOMMUNICATIONS SERVICES, INC.

NOTES TO UNAUDITED FINANCIAL STATEMENTS -- (CONTINUED)

results of operations for the six month period ending June 30, 2000 are not necessarily indicative of the results to be experienced for the fiscal year ending December 31, 2000.

The Statements and related notes herein have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission. Accordingly, certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles have been omitted pursuant to such rules and regulations. The accompanying notes should therefore be read in conjunction with the Company's December 31, 1999 financial statements included elsewhere herein.

INCOME TAXES

Upon the incorporation of ATX, Inc as of February 9, 2000, ATX is subject to federal and state income taxation. ATX did not provide for an income tax benefit for the Six Months ended June 30, 2000 based on the uncertainty of future earnings and profits.

Prior to the incorporation of ATX, Inc., the partners were required to report their respective share of the Company's profits and losses in their individual income tax returns. Accordingly, no provision for federal, state and local income taxes is reflected in these statements for periods prior to February 9, 2000.

4. PHANTOM UNIT PLAN

The Phantom Unit Plan ("the Plan") provides for the issuance of a total of 5,000,000 phantom units. The phantom units shall become payable on the earlier of termination or a change of control. Upon the termination of employment, such phantom unit holders shall be entitled to compensation. Such compensation shall be payable over a 36-month period beginning in the thirteenth month after termination. Compensation is determined by the Phantom Unit Plan's formula and is based on average net income as defined in the Plan for the three years prior to termination.

Upon a change in control as defined in the Plan, the Company will record a compensation charge equal to the fair market value of the phantom units. Such event would be the consummation of the Merger Agreement above resulting in a charge of approximately 5% of the fair market value of the aggregate consideration as described in Note 2.

5. SUPPLEMENTAL CASH FLOW INFORMATION

Prior to the merger into ATX, Inc. distributions were made to the former partners of ATX of approximately $4.3 million to satisfy their loan balances. Additionally, loans to an officer of the Company were forgiven of approximately $1.9 million and shown as a contribution to equity.

ATX TELECOMMUNICATIONS SERVICES GROUP

NOTES TO COMBINED FINANCIAL STATEMENTS

1. ORGANIZATION AND BUSINESS

The combined financial statements of ATX Telecommunications Services Group ("the Company") include the accounts of ATX Telecommunications Services Ltd. ("ATX") and Global Telecom Services, Ltd. ("Global") which were under common control and ownership by the same partners/family members. ATX and Global were limited partnerships organized under the laws of the Commonwealth of Pennsylvania. ATX and Global are single-source providers of voice and data services offering a full range of telecommunications services, including long distance, local, data, private line, cellular, PC-based billing, prepaid calling, paging, Internet access and World Wide Web consulting, development and hosting.

These partnerships were terminated on February 9, 2000 upon their merger into ATX Telecommunication Services, Inc. ("ATX, Inc."). ATX, Inc. was incorporated on the above date in the state of Delaware upon the consent of the Company's partners. ATX, Inc. was capitalized with 10,000 shares of common stock at $.01 par value. Upon the merger, 1,000 shares of common stock was issued to the former partners of ATX and Global. On such date, the Company contributed its assets and its liabilities were assumed by ATX, Inc. at their historical cost basis.

The partnership agreement provides for the allocation of profits and losses on an annual basis. Profits and losses are allocated among partners based on the partnership agreement.

Distributions, other than liquidating distributions, shall be made to all partners in proportion to their percentage interests except as otherwise stipulated in the partnership agreement.

The partnership agreement required that during 1999 certain partners receive distributions totaling $1,350,000 for prior years. This agreement also provides for bonuses to these partners totaling $8,000,000 per year for the years 1998 through 2002. The Company has recorded compensation expenses for these bonuses included in selling, general and administrative expenses for the years ended December 31, 1999 and 1998, respectively.

If a sale or public offering of the Company does not occur before January 31, 2003, certain minority partners have an option to put their respective interests to the Company at fair value, as defined within the partnership agreement. The total amount to be paid to these partners for their respective interests will be paid over a seven and one-half year period.

2. PLAN OF RECAPITALIZATION AND MERGER

On March 9, 2000, ATX, Inc. and its stockholders ("ATX Stockholders") entered into a plan of recapitalization and merger ("Merger Agreement") with CoreComm Limited ("CoreComm"). Under the terms of the merger agreement, ATX will be

F-40

NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)

recapitalized such that the ATX Stockholders will receive the following aggregate consideration: (i) approximately 12.4 million shares of CoreComm common stock; (ii) $250 million of CoreComm's 3% senior preferred stock and
(iii) $150 million in cash from CoreComm. Such amounts may be subject to adjustments as defined in the merger agreement. In the event CoreComm has not completed a debt or equity financing prior to the closing date, CoreComm may elect to issue short term notes of $70 million and reduce the cash consideration by such amount. The Merger Agreement is subject to regulatory and CoreComm shareholder approval, among other conditions.

3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Revenue Recognition

The Company recognizes revenue based on the customers' usage of services. Revenues are presented net of estimated discounts. Additionally, the Company accrues for unbilled telecommunication revenue as a result of its billing cycle and such amounts are included in accounts receivable.

Cost of Revenues

Cost of revenues includes network costs which consist of access, transport, and termination costs. Such costs are recognized when incurred in connection with the provision of telecommunication services.

Cash Equivalents

The Company considers all highly liquid debt instruments purchased with a maturity of three months or less to be cash equivalents.

Property and Equipment

Property and equipment are stated at cost. Depreciation and amortization are provided by the straight-line method over the estimated useful lives of the respective assets. Property and equipment are depreciated over useful lives ranging from five to seven years and leasehold improvements are amortized over the terms of the lease.

Intangible Assets

Intangible assets represent acquired customer lists which are being amortized using the straight line method over a 7-year period. Intangible assets are presented net of accumulated amortization of $522,504, $343,933 and $165,362 as of December 31, 1999, 1998 and 1997, respectively.

F-41

ATX TELECOMMUNICATIONS SERVICES GROUP

NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)

Impairment of Assets

The Company's long-lived assets and identifiable intangibles are reviewed for impairment whenever events or changes in circumstances indicate that the net carrying amount may not be recoverable. When such events occur, the Company measures impairment by comparing the carrying value of the long-lived asset to the estimated undiscounted future cash flows expected to result from the use of the assets and their eventual disposition. The Company determined that, as of December 31, 1999, there had been no impairment in the carrying value of the long-lived and intangible assets.

Advertising and Marketing Costs

All costs related to advertising and marketing the Company's products and services are expensed in the period incurred.

Income Taxes

The partners are required to report their respective share of the Company's profits and losses in their individual income tax returns. Accordingly, no provision for federal, state and local income taxes is reflected in the financial statements.

Concentrations of Credit Risk

The Company maintains its cash deposits and temporary cash investments with high-quality institutions at levels which may exceed federally insured limits. The Company has not experienced any losses on cash deposits or temporary cash investments maintained in this manner.

The Company sells its telecommunications services and products to customers operating primarily in the Northeastern region of the United States. The Company performs ongoing credit evaluation of its customers, and it generally does not require collateral from those customers.

Fair Value of Financial Instruments

The carrying value of all financial instruments approximates their fair value due to the short maturity of the respective instruments.

Use of Estimates

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

10. RETIREMENT PLAN

The Company's employees participate in a defined contribution profit sharing plan established under Section 401(k) of the Internal Revenue Code. The plan allows employees to defer up to 15% of their income through contributions to the plan on a pretax basis, subject to a statutory dollar limitation. In accordance with the provisions of the plan, the employer may match employees' contributions. In addition, the employer may make optional contributions to the plan. The Company and other business entities controlled by a partner of the Company participate in this plan. The Company made matching contributions to the plan for the years ended December 31, 1999, 1998 and 1997 of $176,166, $127,670 and $58,047, respectively.

11. PHANTOM UNIT PLAN

During 1998, ATX adopted the 1998 Phantom Unit Plan (the "Plan"). The Plan provides for the issuance of a total of 5,000,000 phantom units representing a phantom 5% equity interest in ATX. Eligible employees may receive phantom units or equivalent consideration as determined by a committee appointed by ATX to administer the Plan. The committee has the authority at its sole discretion to designate the employees eligible to participate in the Plan. In addition, the committee may terminate or amend the Plan at its discretion. Termination or amendment of the Plan shall not affect phantom awards previously granted. Typically, the awards vest over a seven-year period from the date of grant; however, an employee may receive credit for employment time prior to the date of the award at the discretion of the committee. The Plan is unfunded.

The phantom units become payable to a participant on the earlier of his termination of employment or a change of control. Upon termination of employment, a participant is entitled to compensation under the Plan. Such compensation is payable over a 36-month period beginning in the thirteenth month after termination. The participant's compensation is determined by his proportionate ownership of units and the Plan's formula for determining value, which is 10 times average net cash income as defined in the Plan for the prior three fiscal years.

The Company has recorded a noncash (benefit) charge of ($400,000) and $1,800,000 for the years ended December 31, 1999 and 1998, respectively, related to the issuance of the phantom units.

Upon a change in control as defined in the Plan, the participants will become entitled to receive compensation based upon the exchange or transaction value of ATX's equity. ATX, Inc. will record a compensation charge equal to the fair market value of the consideration payable to the Plan participants less amounts previously recorded. The consummation of the Merger Agreement, described in Note 2 above, would result in a non-cash charge of approximately $44 million.

A-6

NOW, THEREFORE, in consideration of the mutual covenants and agreements set forth herein, Parent, MergerCo and the Company hereby agree as follows:

ARTICLE I

THE MERGER

1.1 The Merger. Subject to the terms and conditions of this Agreement, at the Effective Time, the Company and MergerCo shall consummate the Merger pursuant to which (a) MergerCo shall be merged with and into the Company and the separate corporate existence of MergerCo shall thereupon cease, (b) the Company shall be the successor or surviving corporation in the Merger (sometimes hereinafter referred to as the "Surviving Corporation") and shall continue to be governed by the laws of the State of Delaware and the DGCL, and (c) the separate corporate existence of the Company with all its rights, privileges, immunities, powers and franchises shall continue unaffected by the Merger. Without limiting the generality of the foregoing, and subject thereto, at the Effective Time, all the properties, rights, privileges, powers and franchises of the Company and MergerCo shall vest in the Surviving Corporation, and all debts, liabilities and duties of the Company and MergerCo shall become the debts, liabilities and duties of the Surviving Corporation. The Company shall take such steps as are permitted under the DGCL to (i) amend the Certificate of Incorporation of the Company (the "Company Certificate") so that the Certificate of Incorporation of MergerCo, as in effect immediately prior to the Effective Time, shall be the Certificate of Incorporation of the Surviving Corporation until thereafter amended as provided by law and such Certificate of Incorporation, and (ii) amend the Bylaws of the Company (the "Company Bylaws") so that the Bylaws of MergerCo, as in effect immediately prior to the Effective Time, shall be the Bylaws of the Surviving Corporation until thereafter amended as provided by law, by the Certificate of Incorporation of the Surviving Corporation and by such Bylaws. Notwithstanding the foregoing, the name of the Surviving Corporation shall be "CoreComm-Voyager, Inc." and the Certificate of Incorporation and Bylaws of the Surviving Corporation shall so provide. The Merger shall have the effects specified in the DGCL, including Section 259 of the DGCL.

1.2 Effective Time. As promptly as practicable after all of the conditions set forth in Article IX shall have been satisfied or, if permissible, waived by the party entitled to the benefit of the same, MergerCo and the Company shall duly execute and file a certificate of merger (the "Certificate of Merger") with the Secretary of State of the State of Delaware in accordance with the DGCL. The Merger shall become effective as of the time of the Certificate of Merger has been duly filed or such other subsequent date or time as shall be

agreed upon by the parties and set forth in the Certificate of Merger and in accordance with the DGCL (the "Effective Time").

1.3 Closing. The closing of the Merger (the "Closing") shall take place at such time and on a date to be specified by the parties, which shall be no later than the second business day after satisfaction or waiver of all of the conditions set forth in Article IX

A-7

hereof (the "Closing Date"), at the offices of Paul, Weiss, Rifkind, Wharton & Garrison, 1285 Avenue of the Americas, New York, NY 10019, unless another date or place is agreed to by the parties hereto.

1.4 Tax Consequences. It is intended by all of the parties hereto that the Merger will qualify both or either (i) as a reorganization within the meaning of Section 368(a) of the Code or (ii) a transaction that, together with the Reincorporation (as defined herein) qualifies as an exchange under the provisions of Section 351 of the Code and which is treated for U.S. federal income tax purposes as a transfer of Company Common Stock by the shareholders of the Company to Parent in exchange for the Merger Consideration. All of the parties to this Agreement agree to report the Merger, for all purposes, in a manner which is consistent with the preceding sentence and no party shall take any action, or fail to take any action which action or failure to take such action would cause the Merger to fail to qualify (i) as a reorganization within the meaning of Section 368(a) of the Code or (ii) a transaction that, together with the Reincorporation (as defined herein) qualifies as an exchange under the provisions of Section 351 of the Code and which is treated for U.S. federal income tax purposes as a transfer of Company Common Stock by the shareholders of the Company to Parent in exchange for the Merger Consideration. However, it is further intended by all of the parties hereto that if the transactions with ATX Communications Services, Inc. ("ATX") described in Section 8.11 occur, and this Agreement is assigned as provided in Section 11.5, then the incorporation of ATX, the transactions with ATX described in Section 8.11, and the transactions described in this Agreement will be treated for U.S. federal income tax purposes as one integrated transaction qualifying as an exchange under the provisions of
Section 351 of the Code in which the shareholders of the Company transfer Company Common Stock in exchange for ATX stock.

ARTICLE II

DIRECTORS AND OFFICERS
OF THE SURVIVING CORPORATION

2.1 Directors of the Surviving Corporation. The directors of MergerCo immediately prior to the Effective Time shall be the directors of the Surviving Corporation immediately after the Effective Time until their successors shall have been duly elected or appointed and qualified or until their earlier death, resignation or removal in accordance with the Certificate of Incorporation and Bylaws of the Surviving Corporation. The Company will use reasonable efforts to cause any director who is a designee of the Company on the Board of Directors of any Company Subsidiary to resign as of the Effective Time.

2.2 Officers of the Surviving Corporation. The officers of the Company immediately prior to the Effective Time shall be the officers of the Surviving Corporation immediately after the Effective Time until their successors shall have been duly elected or appointed and qualified or until their earlier death, resignation or removal in accordance with the Certificate of Incorporation and Bylaws of the Surviving Corporation.

A-8

ARTICLE III

EFFECT OF THE MERGER ON THE CAPITAL STOCK
OF THE CONSTITUENT CORPORATIONS

3.1 Effect on Capital Stock. As of the Effective Time, by virtue of the Merger and without any action on the part of the holder of any shares of Company Common Stock or any shares of capital stock of MergerCo:

(a) Each issued and outstanding share of Company Common Stock held by the Company as a treasury share or held by any direct or indirect Company Subsidiary and each issued and outstanding share of Company Common Stock owned by Parent, MergerCo or any other direct or indirect Parent Subsidiary immediately prior to the Effective Time, shall be canceled and retired and cease to exist without any conversion thereof and no payment or distribution shall be made with respect thereto.

(b) Each share of Company Common Stock issued and outstanding immediately prior to the Effective Time, other than those shares referred to in Section 3.1(a), shall be canceled and shall be converted automatically into and represent the right to receive: (i) an amount equal to $3.00, net to the holder in cash, without any interest thereon (plus any cash in lieu of fractional shares as described in Section 4.1(e), the "Cash Consideration") and (ii) that number of fully paid and nonassessable shares of Parent Common Stock equal to $14.00 divided by the Base Stock Price (as defined below) (the "Exchange Ratio") (rounded to the nearest thousandth and subject to adjustment, as provided below, and subject to cash in lieu of fractional shares of Parent Common Stock, if any, pursuant to Section 4.1(e), the "Stock Consideration" and together with the Cash Consideration, the "Merger Consideration").

(c) The Exchange Ratio shall be adjusted as follows:

(i) if the Average Parent Common Stock Price is greater than the Collar Percentage multiplied by the Base Stock Price (such product being the "Ceiling Stock Price"), then the Exchange Ratio shall be adjusted such that the aggregate value (based on the Average Parent Common Stock Price) of the Stock Consideration will be equal to the value the Stock Consideration would represent if the Average Parent Common Stock Price were equal to the Ceiling Stock Price and there were no adjustments to the Exchange Ratio as contemplated in this Section
3.1. The Collar Percentage shall be equal to 119%, subject to the following adjustments: If (1) the Closing has not occurred on or prior to July 15, 2000, (2) subsequent to the date of this Agreement, Parent has engaged in a transaction (other than transactions contemplated by this Agreement or any transaction which would result in a Base Adjustment (as defined below)) (a "Parent Transaction") that would (x) require the approval of the stockholders of Parent or, (y) require Parent to include the information relating to such transaction in the pro forma financial statements (the "Pro Formas") that are required to be contained in the Registration

A-9

Statement or (z) require Parent to amend or restate the Pro Formas in any material manner, and (3) all conditions to Closing have been satisfied (or waived by the party entitled to waive such condition) or are capable of being satisfied on such date with reasonable best efforts, other than the conditions set forth in Sections 9.1(a) and 9.1(d) and the failure of either such condition to be satisfied is the result of a Parent Transaction, then, commencing on the later to occur of (i) July 16, 2000 and (ii) the first business day after which the circumstances set forth in clause (3) are present (such later date being the "Trigger Day") the Collar Percentage shall be increased as follows: 2.5 percentage points on the Trigger Day, and an additional five percentage points per each 31 day period (a "Monthly Period") (on a pro rata basis, based on the actual number of elapsed days in such Monthly Period at the Closing Date) beginning on the sixteenth calendar day following the Trigger Day;

(ii) if the Average Parent Common Stock Price is equal to or greater than 69% of the Base Stock Price and less than 86% of the Base Stock Price (86% of the Base Stock Price being the "Floor Stock Price"), then the Exchange Ratio shall be adjusted such that the aggregate value (based on the Average Parent Common Stock Price) of the Stock Consideration will be equal to the value the Stock Consideration would represent if the Average Parent Common Stock Price were equal to the Floor Stock Price and there were no adjustments to the Exchange Ratio as contemplated in this Section 3.1; and

(iii) subject to the provisions of Section 10.1(i), if the Average Parent Common Stock Price is less than 69% of the Base Stock Price, then the Exchange Ratio will equal that number that it would be set to in clause (ii) above if the Average Parent Common Stock Price were equal to 69% of the Base Stock Price.

For purposes of this Agreement, the "Average Parent Common Stock Price" means the volume weighted average trading price of Parent Common Stock for ten randomly selected trading days out of the twenty (20) consecutive trading days ending with the last trading day prior to the Closing Date. The "Base Stock Price" shall be equal to $47.875, subject to the following "Base Adjustments": (i) if, after the date of this Agreement and on or prior to the Closing Date the outstanding shares of Parent Common Stock shall be changed into a different number of shares by reason of any reclassification, recapitalization, stock split, reverse stock split, combination or exchange of shares, or any dividend payable in Parent Common Stock shall be declared thereon with a record date within such period, or any similar event shall occur, the Base Stock Price shall be adjusted accordingly to provide to the shareholders of the Company the same economic effect as contemplated by this Agreement absent such reclassification, recapitalization, stock split, reverse stock split, combination, exchange, dividend or similar event; and (ii) if, after the date of this Agreement and on or prior to the Closing Date, Parent shall distribute to all holders of Parent Common Stock shares of capital stock of Parent other than Parent Common Stock, evidences of indebtedness or other assets

A-10

(other than cash dividends out of current or retained earnings), or shall distribute to substantially all holders of Common Stock rights or warrants to subscribe for securities (other than those referred to in subsection (i) above), then in each such case the Base Stock Price shall be multiplied by a fraction of which the numerator shall be the Current Market Price (as defined below) of the Parent Common Stock on the record date less the then fair market value (as determined in good faith by the Board of Directors of Parent (the "Parent Board"), whose determination shall be conclusive evidence of such fair market value (absent manifest error or bad faith) and described in a board resolution) of the portion of the assets so distributed or of such subscription rights or warrants applicable to one share of Parent Common Stock and of which the denominator shall be the Current Market Price of the Parent Common Stock. The "Current Market Price" shall mean the volume weighted average trading price of Parent Common Stock for the ten randomly selected trading days out of the prior twenty (20) consecutive trading days. Parent may only effect a distribution described under (ii) above, if such distribution does not include operating assets that are required to maintain the current operating businesses of CoreComm, Inc. (a subsidiary of Parent) and the distribution of such operating assets would not have a material adverse effect on the current operating businesses of CoreComm, Inc., other than the local multipoint distribution service licenses and related assets.

(d) If at any time prior to Closing, either the written opinion of counsel required to be received by the Company pursuant to Section 9.2(e) or the written opinion required to be received by Parent pursuant to
Section 9.3(g) is not reasonably expected to be delivered in a form acceptable to the Company and Parent because less than 80% of the value of the Merger Consideration will be Stock Consideration (determined as of the Closing Date) and all other conditions to Closing set forth in Article IX have been satisfied (or waived by the party entitled to make such condition), then the Merger Consideration shall be adjusted by increasing the Stock Consideration and decreasing the Cash Consideration so that the Stock Consideration shall constitute 80% of the value of the Merger Consideration (determined as of the Closing Date) provided, that, after such adjustment, the Merger qualifies as a reorganization under the provisions of Section 368(a)(2)(E) of the Code.

(e) Each share of common stock, par value $.01 per share, of MergerCo (the "MergerCo Common Stock") issued and outstanding immediately prior to the Effective Time shall be converted into one validly issued, fully paid and non-assessable share of common stock, par value $.01 per share, of the Surviving Corporation (the "Surviving Corporation Common Stock"), certificates for which shall be issued to the stockholders of MergerCo on a pro rata basis in accordance with their respective shares of MergerCo upon surrender to the Surviving Corporation of such stockholders' certificates formerly representing such shares of MergerCo Common Stock.

(f) All shares of Company Common Stock, when converted as provided in
Section 3.1(b), shall no longer be outstanding and shall automatically be canceled

A-11

and retired and shall cease to exist, and each Certificate previously evidencing such shares shall thereafter represent only the right to receive the Merger Consideration and cash in lieu of fractional shares of Parent Common Stock in accordance with Sections 3.1(b) and 4.1(e) and any distribution or dividend under Section 4.1(c). The holders of Certificates previously evidencing shares of Company Common Stock outstanding immediately prior to the Effective Time shall cease to have any rights with respect to the Company Common Stock except as otherwise provided herein or by law and, upon the surrender of Certificates in accordance with the provisions of Article III hereof, shall only represent the right to receive for their shares of Company Common Stock the Merger Consideration and cash in lieu of fractional shares of Parent Common Stock in accordance with Sections 3.1(b) and 4.1(e) and any distribution or dividend under Section 4.1(c) in each case without interest.

3.2 Company Stock Options and Related Matters.

(a) Each option (collectively, the "Company Options") granted under the Company's Amended and Restated 1998 Stock Option and Incentive Plan (the "Company Stock Option Plan"), which is outstanding (whether or not then exercisable) as of immediately prior to the Effective Time and which has not been exercised or canceled prior thereto, shall, at the Effective Time, be assumed by Parent, subject to the provisions of this Section 3.2 (the "Assumed Options"). The Assumed Options shall not terminate in connection with the Merger and shall continue to have, and be subject to, the same terms and conditions as set forth in the Company Stock Option Plan and agreements (as in effect immediately prior to the Effective Time) pursuant to which the Company Options were granted, provided that (i) all references to the Company shall be deemed to be references to Parent and all references to shares of Company Common Stock shall be deemed to be references to shares of Parent Common Stock, (ii) each Company Option shall be exercisable for that number of whole shares of Parent Common Stock equal to the product of the number of shares of Company Common Stock covered by such Company Option immediately prior to the Effective Time multiplied by the Option Exchange Ratio (as defined below) and rounded to the nearest whole number of shares of Parent Common Stock and (iii) the exercise price per share of Company Common Stock under such Company Option shall be equal to the exercise price per share of Company Common Stock under the Company Option divided by the Option Exchange Ratio and rounded to the nearest cent. Parent shall (A) reserve for issuance the number of shares of Parent Common Stock that will become issuable upon the exercise of such Assumed Options pursuant to this
Section 3.2, (B) promptly after the Effective Time issue to each holder of a Company Option a document evidencing the assumption by Parent of the Company's obligations with respect thereto under this Section 3.2, and (C) promptly after the Effective Time, cause to be filed a registration statement on an appropriate form under the Securities Act of 1933, as amended (the "Securities Act"), relating to the Company Stock Option Plans then in effect and covering the shares of Parent Common Stock issuable upon exercise of the Assumed Options. As used in this Section 3.2, "Option Exchange Ratio" means the sum of

A-12

(i) the Exchange Ratio (as it may be adjusted) and (ii) the quotient obtained by dividing the per share Cash Consideration by the Average Parent Common Stock Price.

(b) The adjustments provided in this Section 3.2 with respect to any Company Options that are "incentive stock options" as defined in Section 422 of the Code, shall be and are intended to be effected in a manner which is consistent with Section 424(a) of the Code.

(c) The parties to this Agreement shall take all reasonable action required to exempt under SEC Rule 16(b)-3 the treatment of options contemplated hereby, including, if necessary or appropriate, obtaining approvals, by each party's Board of Directors, of the type described in a pertinent SEC no-action letter dated January 12, 1999.

ARTICLE IV

PAYMENT OF SHARES

4.1 Payment for Shares of Company Common Stock.

(a) From and after the Effective Time, such bank or trust company designated by Parent, and reasonably acceptable to the Company, shall act as exchange agent (the "Exchange Agent"). At or prior to the Effective Time, MergerCo shall deposit, or MergerCo shall otherwise take all steps necessary to cause to be deposited, with the Exchange Agent the aggregate Merger Consideration and the cash in lieu of fractional shares of Parent Common Stock (such aggregate Merger Consideration and cash in lieu of shares of Parent Common Stock together with any dividends or distributions with respect thereto to which the holders of Certificates may be entitled pursuant to Section 4.1(c) being hereinafter referred to as the "Exchange Fund") to which holders of shares of Company Common Stock shall be entitled pursuant to Section 3.1.

(b) Promptly after the Effective Time, Parent shall cause the Exchange Agent to mail to each holder of record of a Certificate or Certificates other than the Company, Parent, MergerCo or any Parent Subsidiary (i) a letter of transmittal which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates to the Exchange Agent and shall be in such form and have such other provisions as Parent may reasonably specify and (ii) instructions for use in effecting the surrender of the Certificates in exchange for the Merger Consideration and cash in lieu of fractional shares of Parent Common Stock. Upon surrender of a Certificate for cancellation to the Exchange Agent together with such letter of transmittal, duly executed and completed in accordance with the instructions thereto, the holder of such Certificate shall be entitled to receive in exchange therefor (x) a certificate representing the number of whole shares of Parent Common Stock representing the Stock Consideration to which such holder shall be entitled, (y) a check representing the amount of the Cash Consideration to which such holder shall be entitled and (z) a check representing the amount of cash in lieu of fractional shares of Parent Common Stock, if any, plus the amount of any dividends (other than stock dividends), or distributions, if any, pursuant to paragraph (c) below, in the case of

A-13

(y) and (z), after giving effect to any required withholding tax, and the Certificate so surrendered shall forthwith be canceled. No interest will be paid or accrued on the Cash Consideration or on cash payable in lieu of fractional shares or on the dividend or distribution, if any, payable to holders of Certificates pursuant to this Section 4.1. In the event of a transfer of ownership of Company Common Stock which is not registered in the transfer records of the Company, a Certificate representing the proper number of shares of Parent Common Stock, together with checks for the Cash Consideration to which such holder shall be entitled and for any cash to be paid in lieu of fractional shares of Parent Common Stock plus, to the extent applicable, the amount of any dividend or distribution, if any, payable pursuant to paragraph (c) below, may be issued and paid to such a transferee if the Certificate representing shares of such Company Common Stock is presented to the Exchange Agent, accompanied by all documents required to evidence and effect such transfer and to evidence that any applicable stock transfer taxes have been paid. If any certificate for shares of Parent Common Stock is to be issued in a name other than that in which the surrendered Certificate is registered, it shall be a condition of such exchange that the person requesting such exchange shall pay any transfer or other taxes required by reason of the issuance of certificates for shares of Parent Common Stock in a name other than that of the registered holder of the surrendered Certificate, or shall establish to the satisfaction of Parent or the Exchange Agent that such tax has been paid or is not applicable.

(c) Notwithstanding any other provisions of this Agreement, no dividends or other distributions on Parent Common Stock shall be paid with respect to any shares of Company Common Stock represented by a Certificate until such Certificate is surrendered for exchange as provided herein; provided, however, that subject to the effect of applicable laws, following surrender of any such Certificate, there shall be paid to the holder of the certificates representing whole shares of Parent Common Stock issued in exchange therefor, without interest, (i) at the time of such surrender, the amount of dividends or other distributions with a record date after the Effective Time theretofore payable with respect to such whole shares of Parent Common Stock and not paid, less the amount of any withholding taxes which may be required thereon, and (ii) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Effective Time but prior to surrender and a payment date subsequent to surrender payable with respect to such whole shares of Parent Common Stock, less the amount of any withholding taxes which may be required thereon.

(d) At and after the Effective Time, there shall be no transfers on the stock transfer books of the Company of the shares of Company Common Stock which were outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates are presented to the Surviving Corporation, they shall be canceled and exchanged for the Merger Consideration and cash in lieu of fractional shares, if any, in accordance with this Section 4.1 (plus dividends and distributions to the extent set forth in Section 4.1(c), if any).

(e) No certificates or scrip representing fractional shares of Parent Common Stock shall be issued upon the surrender for exchange of Certificates, and such fractional share

A-14

interest will not entitle its owner to vote, to receive dividends or to any other rights of a stockholder of Parent. In lieu of the issuance of any fractional shares of Parent Common Stock pursuant to Section 3.1(b), the Exchange Agent shall pay to each holder of shares of Company Common Stock exchanged pursuant to the Merger who are entitled to receive a fraction of a share of Parent Common Stock (after taking into account all Certificates delivered by such holder) in accordance with the provisions of this Article IV, an amount in cash equal to the product obtained by multiplying (A) the fractional shares of Parent Common Stock to which such holder is entitled (after taking into account all shares of Company Common Stock held at the Effective Time) by (B) the closing price for a share of Parent Common Stock on NASDAQ on the first business day immediately following the Effective Time.

(f) Any portion of the Exchange Fund (including the proceeds of any investments thereof and any shares of Parent Common Stock) that remains unclaimed by the former stockholders of the Company one year after the Effective Time shall be delivered to the Surviving Corporation. Any former stockholders of the Company who have not theretofore complied with this Article IV shall thereafter look only to the Surviving Corporation for payment of their Merger Consideration and cash in lieu of fractional shares (plus dividends and distributions to the extent set forth in Section 4.1(c), if any), as determined pursuant to this Agreement, without any interest thereon. None of Parent, MergerCo, the Company, the Exchange Agent or any other person shall be liable to any former holder of shares of Company Common Stock for any amount properly delivered to a public official pursuant to applicable abandoned property, escheat or similar laws. If any Certificates shall not have been surrendered prior to five years after the Effective Time (or immediately prior to such earlier date on which any Merger Consideration in respect of such Certificate would otherwise escheat to or become the property of any Governmental Entity (as defined herein)), any amounts payable in respect of such Certificate shall, to the extent permitted by applicable law, become the property of the Surviving Corporation, free and clear of all claims or interests of any person previously entitled to those amounts. In the event any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Certificate to be lost, stolen or destroyed and, if required by the Surviving Corporation, the posting by such person of a bond in such reasonable amount as the Surviving Corporation may direct as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent or the Surviving Corporation will issue and pay in exchange for such lost, stolen or destroyed Certificate the Merger Consideration and cash in lieu of fractional shares (plus, to the extent applicable, dividends and distributions payable pursuant to Section 4.1(c)) in each case without interest.

(g) Each of the Surviving Corporation and Parent shall be entitled to deduct and withhold from any amounts otherwise payable pursuant to this Agreement to any holder of a Certificate such amounts as it is required to deduct and withhold with respect to the making of such payment under the Code, or any provisions of Law. To the extent that amounts are so withheld by the Surviving Corporation or Parent, as the case may be, such withheld amounts shall be treated for purposes of this Agreement as having been

A-15

paid to the holder of a Certificate in respect to which such deduction and withholding was made by the Surviving Corporation or Parent, as the case may be.

ARTICLE V

REPRESENTATIONS AND WARRANTIES OF THE COMPANY

Except as set forth in the disclosure letter delivered at or prior to the execution hereof to Parent, which shall refer to the relevant Sections of this Agreement (the "Company Disclosure Schedule"), the Company represents and warrants to Parent and MergerCo as follows:

5.1 Existence; Good Standing; Authority; Compliance With Law.

(a) The Company is a corporation duly organized, validly existing and in good standing under the laws of the State of Delaware. Except as set forth in
Section 5.1 of the Company Disclosure Schedule, the Company is duly licensed or qualified to do business as a foreign corporation and is in good standing under the laws of any other state of the United States in which the character of the properties owned, leased or operated by it therein or in which the transaction of its business makes such qualification or licensing necessary, except where the failure to be so licensed or qualified would not, individually or in the aggregate, reasonably be expected to have a material adverse effect on the business, assets, properties, results of operations or financial condition of the Company and the Company Subsidiaries (as defined herein) taken as a whole (a "Company Material Adverse Effect"). The Company has all requisite corporate power and authority to own, operate, lease and encumber its properties and carry on its business as now conducted.

(b) Each of the Company Subsidiaries is a corporation, partnership or limited liability company (or similar entity or association in the case of those Company Subsidiaries organized and existing other than under the laws of a state of the United States) duly incorporated or organized, validly existing and in good standing under the laws of its jurisdiction of incorporation or organization, has the corporate or other power and authority to own its properties and to carry on its business as it is now being conducted, and is duly qualified or licensed to do business and is in good standing in each jurisdiction in which the character of the properties owned, leased or operated by it therein or in which the transaction of its business makes such qualification or licensing necessary, except as set forth in Section 5.1(b) of the Company Disclosure Schedule and except for jurisdictions in which such failures to be so qualified or to be in good standing would not, individually or in the aggregate, reasonably be expected to have a Company Material Adverse Effect.

(c) Neither the Company nor any of the Company Subsidiaries is in violation of any order of any court, Governmental Entity or arbitration board or tribunal, or any domestic law, statute, order, judgment, decree, ordinance, rule or regulation ("Law"), applicable to the Company or any Company Subsidiary or by which any of their respective properties or assets is bound or affected, which violations would, individually or in the aggregate, reasonably be expected to have a Company Material Adverse Effect.

A-16

(d) The Company and the Company Subsidiaries have obtained all franchises, grants, authorizations, licenses, permits, easements, variances, exceptions, consents, waivers, rights, certificates, approvals and orders of, and registrations required to be made with, any United States (federal, state or local) government, or governmental, regulatory or administrative authority, agency or commission, court or arbitrator of competent jurisdiction or stock exchange (each of the foregoing, a "Governmental Entity") that are material to its business as it is now being or is intended to be conducted (the "Company Permits"), except where failure to obtain any such Company Permit would not, individually or in the aggregate, reasonably be expected to have a Company Material Adverse Effect.

Parent has filed all required forms, reports, exhibits, schedules, statements and other documents with the SEC since September 2, 1998 (collectively, the "Parent SEC Reports"), all of which were prepared in accordance with the applicable requirements of the Securities Laws. All required Parent SEC Reports have been filed with the SEC and constitute all forms, reports, exhibits, schedules, statements and other documents required to be filed by Parent under the Securities Laws since September 2, 1998. As of their respective dates, Parent SEC Reports, including any financial statement or schedules included or incorporated therein by reference (i) complied as to form in all material respects with the applicable requirements of the Securities Laws and (ii) did not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements

A-39

made therein, in the light of the circumstances under which they were made, not misleading. Each of the consolidated balance sheets of Parent included in or incorporated by reference into Parent SEC Reports (including the related notes and schedules) fairly presents the consolidated results of operations and cash flow position of Parent and Parent Subsidiaries as of its date and each of the consolidated statements of income, retained earnings and cash flows of Parent included in or incorporated by reference into Parent SEC Reports (including any related notes and schedules) fairly presents the results of operations, retained earnings or cash flows, as the case may be, of Parent and Parent Subsidiaries for the periods set forth therein (subject, in the case of unaudited statements, to normal year-end audit adjustments which would not be material in amount or effect), in each case in accordance with generally accepted accounting principles consistently applied during the periods involved, except as may be noted therein and except, in the case of the unaudited statements, as permitted by Form 10-Q pursuant to Section 13 or 15(d) of the Exchange Act. All of such balance sheets and statements complied as to form in all material respects with applicable accounting requirements and with the published rules and regulations of the SEC with respect thereto. No Parent Subsidiary is subject to the periodic reporting requirements of the Exchange Act or is otherwise required to file any documents with the SEC or any national securities exchange or quotation service or comparable Governmental Entity.

6.8 Litigation. Except as set forth in Section 6.8 of Parent Disclosure Schedule and in the Parent SEC Reports, there is no litigation, suit, claim, action or proceeding pending or, to the knowledge of Parent, threatened against Parent or any of Parent Subsidiaries, as to which there is a reasonable likelihood of an adverse determination and which, if adversely determined, would, individually or in the aggregate, reasonably be expected to have a Parent Material Adverse Effect. Neither Parent nor any Parent Subsidiary is subject to any outstanding order, writ, injunction or decree which, individually or in the aggregate, has resulted or would, individually or in the aggregate, reasonably be expected to have a Parent Material Adverse Effect.

6.9 Absence of Certain Changes. Except as disclosed in Parent SEC Reports filed with the SEC between September 30, 1999 and the date of this Agreement or in Section 6.9 of the Parent Disclosure Schedule, since September 30, 1999 Parent and Parent Subsidiaries have conducted their businesses only in the ordinary course of business and there has not been:

(a) any declaration, setting aside or payment of any dividend or other distribution with respect to Parent Common Stock or any redemption, purchase or other acquisition of Parent's securities;

(b) any Commitment entered into by Parent or any of Parent Subsidiaries outside the ordinary course of business except for Commitments for expenses of attorneys, accountants and investment bankers incurred in connection with the Transactions;

(c) any material change in Parent's accounting principles, practices or methods; or

A-40

(d) any damage, destruction or other casualty loss with respect to any asset or property owned, leased or otherwise used by it or any Parent Subsidiaries, whether or not covered by insurance, which damage, destruction or loss, individually or in the aggregate, has resulted or would, individually or in the aggregate, reasonably be expected to have a Parent Material Adverse Effect.

6.10 Intellectual Property. Parent or the Parent Subsidiaries are the owner free and clear of any Liens of, or a licensee under a valid unrestricted license for, all Intellectual Property which are material to the business of Parent and the Parent Subsidiaries as currently conducted, taken as a whole. Except as disclosed in Parent SEC Reports or Section 6.10 of Parent Disclosure Schedule, there are no claims pending or, to Parent's knowledge, threatened, that Parent or any Parent Subsidiary is in violation of any such intellectual property right of any third party or that challenges the validity, enforceability, ownership, or right to use, sell, or license any Intellectual Property which would, individually or in the aggregate, reasonably be expected to have a Parent Material Adverse Effect, and, to Parent's knowledge, no third party is in violation of any intellectual property rights of Parent or any Parent Subsidiary which would, individually or in the aggregate, reasonably be expected to have a Parent Material Adverse Effect.

6.11 No Brokers. Neither Parent nor any of Parent Subsidiaries has entered into any contract, arrangement or understanding with any person or firm which may result in the obligation of such entity or the Company to pay any finder's fees, brokerage or agent's commissions or other like payments in connection with the negotiations leading to this Agreement or consummation of the Transactions, except that Parent has retained Goldman, Sachs & Co. and Albert Schneider as its financial advisor in connection with the Transactions. Other than the foregoing arrangements and the Company's arrangements with Morgan Stanley, Parent is not aware of any claim for payment of any finder's fees, brokerage or agent's commissions or other like payments in connection with the negotiations leading to this Agreement or consummation of the Transactions.

6.12 Opinion of Financial Advisor. Parent has received the opinion of Goldman, Sachs & Co. to the effect that, as of the date hereof, the Merger Consideration is fair to the holders of Parent Common Stock from a financial point of view.

6.13 Taxes. Except as set forth in Section 6.13 of the Parent Disclosure Schedule, each of the Parent and the Parent Subsidiaries (i) has filed, or will have filed, all Tax Returns required to be filed by it on or before the Closing Date (taking into account any applicable extensions) and all such Tax Returns are true, correct and complete in all material respects, and (ii) has paid, or will have paid, all Taxes required to be paid by it on or before the Closing Date (whether or not shown on any Tax Return), except, in each case, where the failure to file such Tax Returns or pay such Taxes would not, individually or in the aggregate, reasonably be expected to have a Parent Material Adverse Effect. Except as set forth in Section 6.13 of the Parent Disclosure Schedule, the most recent unaudited financial statements contained in the Parent's Quarterly Report on Form 10-Q for the quarter ended September 30, 1999 reflect an adequate reserve for all material Taxes payable by the Parent and the Parent Subsidiaries for all taxable periods and portions thereof through the date of such financial statements in

A-41

accordance with United States GAAP. To the knowledge of the Parent, and except as set forth in Section 6.13 of the Parent Disclosure Schedule, no deficiencies for any Taxes have been proposed, asserted or assessed against the Parent or any of the Parent Subsidiaries, there are no Tax liens on any assets of the Parent or of any of the Parent Subsidiaries (other than liens for current Taxes not yet due), and no requests for waivers of the time to assess any such Taxes are pending. The transactions described in Section 8.11, including the Reincorporation (as defined herein), will not result in any material Tax liability to Parent or to ATX.

6.14 Employee Benefit Plans. Each Parent Benefit Plan which is intended to be qualified under Section 401(a) of the Code has received a favorable determination or approval letter from the IRS regarding its qualification under such section, and neither the Parent nor any Affiliate knows of any event that has occurred which would preclude qualified status. With respect each Parent Benefit Plan, there has been no material failure to comply with any applicable provision of ERISA, the Code or any other law which would subject the Parent or any Affiliate to liability for any damages, penalty, or taxes that would, individually or in the aggregate, reasonably be expected to have a Parent Material Adverse Effect.

6.15 Definition of Parent's Knowledge. As used in this Agreement, the phrase "to the knowledge of Parent" or any similar phrase means the actual (and not the constructive or imputed) knowledge after due inquiry of the executive officers of Parent.

(d) Nothing contained in this Section 7.1 shall prohibit the Company from at any time taking and disclosing to its stockholders a position contemplated by Rule 14d-9 or Rule 14e-2 promulgated under the Exchange Act or making any disclosure required by Rule 14a-9 promulgated under the Exchange Act if, the Company Board determines, in its good faith reasonable judgment after consultation with outside legal counsel, that failure to so disclose would be inconsistent with its obligations under applicable law.

(ix) make or file and elections in respect of Taxes with respect to the Company or any of its Subsidiaries;

7.3 Tax-Free Treatment. Parent, MergerCo and the Company intend that the Merger will qualify as either (i) a reorganization within the meaning of Section 368(a) of the Code or (ii) a transaction that, together with the Reincorporation (as defined herein) qualifies as an exchange under the provisions of Section 351 of the Code and which is treated for U.S. federal income tax purposes as a transfer of Company Common Stock by the shareholders of the Company to Parent in exchange for the Merger Consideration. None of Parent, MergerCo or the Company shall take, or fail to take, or cause to be taken or fail to cause to be taken, any action, whether before or after the Closing, which action or failure to take any action would cause the Merger to fail to constitute a "reorganization" within the meaning of Section 368(a) of the Code or a transaction that, together with the Reincorporation (as defined herein) qualifies as an exchange under the provisions of Section 351 of the Code and which is treated for U.S. federal income tax purposes as a transfer of Company Common Stock by the shareholders of the Company to Parent in exchange for the Merger Consideration. However, it is further intended by all of the parties hereto that if the transactions with ATX described in Section 8.11 occur, and this Agreement is assigned as provided in
Section 11.5, then the incorporation of ATX, the transactions with ATX described in Section 8.11, and the transactions described in this Agreement will be treated for U.S. federal income tax purposes as one integrated transaction qualifying as an exchange under the provisions of Section 351 of the Code in which the shareholders of the Company transfer Company Common Stock in exchange for ATX stock. No party to this Agreement shall take a position on any Tax return that is inconsistent with the intentions expressed in this Section 7.3.

No amendment or supplement to the Proxy Statement will be made without the approval of each of Parent and the Company, which approval shall not be unreasonably withheld or delayed. Each of Parent and the Company agrees that the information provided by it for inclusion in the Proxy Statement or the Form S-4 and each amendment or supplement thereto, at the time of

A-50

mailing thereof and at the time of the respective meetings of stockholders of Parent and the Company, will not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading. Each of the Company and Parent will advise the other, and deliver copies (if any) to the other, promptly after either receives notice thereof, of any request by the SEC for amendment of the Proxy Statement or the Form S-4 or comments thereon and responses thereto or requests by the SEC for additional information, or notice of the time when the Form S-4 has become effective or any supplement or amendment has been filed, the issuance of any stop order or the suspension of the qualification of the Registered Securities issuable in connection with the Merger for offering or sale in any jurisdiction.

In the event that $ 750,000 is insufficient for the above referenced coverage, the Company may spend up to that amount to purchase such lesser coverage as is possible.

Except as expressly set forth in this Agreement, there are no representations or warranties of any party hereto, express or implied.

11.4 Miscellaneous. This Agreement (i) constitutes, together with the Confidentiality Agreement, Parent Disclosure Schedule and the Company Disclosure Schedule, the entire agreement and supersedes all of the prior agreements and understandings, both written and oral, among the parties, or any of them, with respect to the subject matter hereof, (ii) shall be binding upon and inure to the benefits of the parties hereto and their respective successors and assigns and is not intended to confer upon any other person (except as set forth below) any rights or remedies hereunder and (iii) may be executed in two or more counterparts which together shall constitute a single agreement. Except as provided in Section 8.7, this Agreement is not intended to confer upon any person other than the parties to this Agreement any rights or remedies under this Agreement. The parties hereto agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached.

11.6 Severability. If any provision of this Agreement, or the application thereof to any person or circumstance is held invalid or unenforceable, the remainder of this Agreement, and the application of such provision to other persons or circumstances, shall not be affected thereby, and to such end, the provisions of this Agreement are agreed to be severable.

11.7 Choice of Law/Consent to Jurisdiction. All disputes, claims or controversies arising out of this Agreement, or the negotiation, validity or performance of this Agreement, or the Transactions shall be governed by and construed in accordance with the laws of the State of Delaware without regard to its rules of conflict of laws.

Each of the parties hereto agrees, (a) to the extent such party is not otherwise subject to service of process in the State of Delaware, to appoint and maintain an agent in the State of Delaware as such party's agent for acceptance of legal process, and (b) that service of process may also be made on such party by prepaid certified mail with a proof of mailing receipt validated by the United States Postal Service constituting evidence of valid service. Service made pursuant to (a) or (b) above shall have the same legal force and effect as if served upon such party personally within the State of Delaware. For purposes of implementing the parties' agreement to appoint and maintain an agent for service of process in State of Delaware, each such party does hereby appoint The Corporation Trust Company, 1209 Orange Street, Wilmington, New Castle County, Delaware 19801, as such agent.

Any shares of Company Common Stock as to which the holder thereof shall have properly demanded appraisal in accordance with the requirements of Section 262 of the DGCL (any holder duly making such demand is referred to herein as a "Dissenting Stockholder") shall not be converted into the right to receive the Merger Consideration, unless and until such holder shall have failed to perfect, or shall have effectively withdrawn or lost, the right to appraisal of and payment for such shares of Common Stock under the DGCL, but instead such holder shall be entitled only to such rights as are provided for under
Section 262 of the DGCL.

EXHIBIT B

FORM OF REGISTRATION RIGHTS AGREEMENT

REGISTRATION RIGHTS AGREEMENT, dated as of , 2000 (the "Agreement"), by and between [CoreComm Limited], a corporation ("CoreComm" or the "Company") and the holders of Common Stock (as hereinafter defined) listed on Schedule 1 attached hereto (each a "Stockholder" and, collectively, the "Stockholders").

WHEREAS, pursuant to an Agreement and Plan of Merger, dated as of March , 2000 (the "Merger Agreement"), by and among the Company, CoreComm Group Sub I, Inc., a Delaware corporation and a wholly-owned subsidiary of Parent, and Voyager.net, Inc., a Delaware corporation, and, with respect to certain provisions thereof, each of the Stockholders is entitled to receive shares of the Company's common stock, par value $.01 per share (the "Common Stock") and cash;

WHEREAS, it is a condition to the consummation of the merger and the other transactions contemplated by the Merger Agreement that the Company grant to the Stockholders the registration rights and other rights set forth herein; and

In consideration of the mutual covenants and agreements set forth herein and for good and valuable consideration, the receipt of which is hereby acknowledged, the parties hereto agree as follows:

1. General; Securities Subject to this Agreement.

1.1 Grant of Rights. The Company hereby grants registration rights to the Stockholders upon the terms and subject to the conditions set forth in this Agreement. Capitalized terms used herein and not defined shall have the meanings assigned to such terms in the Merger Agreement.

1.2 Registrable Securities. For the purposes of this Agreement, "Registrable Securities" means any shares of Common Stock issued to the Stockholders pursuant to the Merger Agreement; provided, however, that (i) shares shall cease to be Registrable Securities for purposes of this Agreement when a registration statement covering such Registrable Securities has been declared effective under the Securities Act by the Commission and all such Registrable Securities have been disposed of pursuant to such effective registration statement and (ii) the securities of a Stockholder shall be deemed not to be Registrable Securities at any time when the entire amount of such Stockholder's Registrable Securities proposed to be sold in a single sale are or, in the opinion of counsel satisfactory to the Company, in its reasonable judgment, may be distributed to the public pursuant to Rule 144 (or any successor provision then in effect) under the Securities Act.

1.3 Stockholders of Registrable Securities. A Person is deemed to be a holder of Registrable Securities whenever such Person (i) is a party to this Agreement (or a permitted transferee thereof) and (ii) owns of record Registrable Securities. If the Company receives conflicting instructions, notices or elections from two or more

A-74

Persons with respect to the same Registrable Securities, the Company may act upon the basis of the instructions, notice or election received from the registered owner of such Registrable Securities.

2. Demand Registration Rights.

2.1 Demand Registration.

(a) At any time on or after six (6) months from the date of this Agreement, the Stockholders may make a written request (specifying the intended method of disposition) (such Stockholders, the "Initiating Stockholders") for registration under the Securities Act (a "Demand Registration") of all or part of the shares of Common Stock which constitute such Initiating Stockholders' Registrable Securities; provided, however, that, (i) the Company shall not be required to effect more than one (1) Demand Registration pursuant to this Agreement, (ii) the number of the shares of Common Stock proposed to be registered by the Initiating Stockholders shall not be less than 1,500,000 shares (subject to appropriate adjustments to reflect stock splits, stock dividends, corporate recapitalizations or similar transactions) as of the date of the request, and (iii) the Initiating Stockholders shall be the holders as of the date of the request of at least 43.5% of the then outstanding shares of Common Stock that constitute Registrable Securities hereunder.

(b) If at the time of any request to register Registrable Securities pursuant to this Section 2.1, the Company is engaged or plans to engage in within ninety (90) days of the time of such request in a registered public offering or any other activity which, in the good faith determination of the Board of Directors of the Company, would be required to be disclosed under applicable law as a result of such request or would be materially and adversely affected by the requested registration (each, a "Company Event"), then the Company may at its option direct that such request be delayed for a reasonable period of time not in excess of three (3) months from the effective date of such offering or the date of completion of such other activity, as the case may be, such right to delay a request to be exercised by the Company not more than once in any 365-day period. In addition, the Company shall not be required to effect any registration within three (3) months after the effective date of any other Registration Statement of the Company. Within ten days after receipt of a request for a Demand Registration, the Company shall give written notice (the "Notice") of such request to all other Stockholders holding the class of stock to which such Demand Registration relates and shall include in such registration all Registrable Securities of that class that the Company has received written requests for inclusion therein within 15 days after the Notice is given. Thereafter, in the case of Demand Registration, the Company may elect to include in such registration additional shares of Common Stock issued by the Company. All requests made pursuant to this Section 2.1 shall specify the class and aggregate number of Registrable Securities to be registered.

2.2 Effective Demand Registration. The Company shall use reasonable commercial efforts to cause any Demand Registration to become effective not later than

A-75

ninety (90) days after it receives a request under Section 2.1 hereof and to remain effective for the lesser of (i) the period during which all Registrable Securities registered in the Demand Registration are sold and
(ii) one hundred and twenty (120) days; provided, however, that if the Initiating Stockholders request the Company to withdraw such registration, other than as the result of a breach by the Company, it shall constitute a Demand Registration unless the Initiating Stockholders promptly pay all of the costs and expenses incurred by the Company in connection with such registration.

2.3 Underwriting Procedures.

(a) The offering of Registrable Securities pursuant to a Demand Registration shall be in the form of a firm commitment underwritten offering and the managing underwriter and other underwriters selected for such offering shall be selected by the Company, provided that the managing underwriter and other underwriters are reasonably acceptable to the Initiating Stockholders (having due regard to the experience and relationship with the Company of the managing underwriter and the other underwriters) (the "Approved Underwriter"). In such event, if the Approved Underwriter advises the Company in writing that in its opinion the aggregate amount of such Registrable Securities requested to be included in such offering is sufficiently large to have a material adverse effect on the success of such offering, the Company shall include in such registration only the aggregate amount of Registrable Securities that in the opinion of the Approved Underwriter may be sold without any such material adverse effect and shall reduce pro rata based on the number of Registrable Securities included in the request for Demand Registration, the amount of Registrable Securities to be included by each Stockholder in such registration.

(b) Distribution by Underwriters. The managing underwriter or underwriters selected for any offering shall enter into an agreement with the Company and the Stockholders whereby the underwriters shall be prohibited from (i) distributing 5% or greater of the Registrable Securities to any Person in connection with the initial placement of the Registrable Securities for the offering and from (ii) distributing 5% or greater of the Registrable Securities to any Person for 90 days after such initial placement.

3. Incidental or "Piggy-Back" Registration Rights.

3.1 Notice of Registration. If, at any time or from time to time prior to the second anniversary of the date hereof, the Company shall determine to register any of its Common Stock for sale in an Underwritten Offering for its own account (other than a registration relating to (i) a registration of an employee compensation plan or arrangement adopted in the ordinary course of business on Form S-8 (or any successor form) or any dividend reinvestment plan or (ii) a registration of securities on Form S-4 (or any successor form) including, without limitation, in connection with a proposed issuance in exchange for securities or assets of, or in connection with a merger or consolidation with another corporation), the Company will promptly give to the Stockholders written notice thereof, and include in such

A-76

registration (subject to Section 3.2) all the Registrable Securities specified in a written request made by any one or more of the Stockholders within ten days after such Stockholder's receipt of such written notice from the Company ("Incidental Registration"). The right of such Stockholder to have Registrable Securities included in a registration pursuant to this
Section 3.1 shall be conditioned upon such Stockholder's entering into (together with the Company and/or the other holders, if any, distributing their securities through such underwriting) an underwriting agreement in customary form with the managing underwriter or underwriters selected for such underwriting by the Company (the "Company Underwriter").

3.2 Cutback. If the lead managing underwriter of an offering covered by Section 3.1 shall advise the Company in writing on or before the date five days prior to the date then scheduled for such offering that, in its opinion, the amount of Common Stock (including Registrable Securities) requested to be included in such registration exceeds the amount which can be sold in such offering without adversely affecting the distribution of the Common Stock being offered, then the Company will include in such registration: first, any shares proposed to be offered by the Company; second, Registrable Securities requested to be registered by the Stockholders and any other shares requested by other stockholders of the Company, including the Stockholders, to be included in such registration, allocated, if necessary, pro rata among the Stockholders and such other holders requesting such registration on the basis of the number of the shares Beneficially Owned at the time, provided, however, that in the event the Company will not, by virtue of the foregoing cut-back mechanism, include in any such registration all of the Registrable Securities requested to be included in such registration, the Stockholders may, upon written notice to the Company given within three days of the time the Stockholders first are notified of such matter, reduce the amount of Registrable Securities they desire to have included in such registration, whereupon only the Registrable Securities, if any, they desire to have included will be considered for such inclusion.

3.3 Right of Termination. The Company shall have the right to terminate or withdraw any registration initiated by it under Section 3.2 prior to the effectiveness of such registration whether or not the Stockholders have elected to include Registrable Securities in such registration.

4. Provisions Applicable to Demand and Piggy-Back Registrations.

4.1 Expenses. The Company shall pay all Registration Expenses (as defined in Section 6 hereof) incurred in connection with any registration pursuant to Section 2 or 3 hereto, unless such registration fails to become effective as a result of the fault of one or more Stockholders, in which case the Company will not be required to pay the Registration Expenses incurred with respect to the offering of such Stockholder's or Stockholders' Registrable Securities. The Registration Expenses incurred with respect to the offering of such Stockholder's or Stockholders' Registrable Securities shall be the product of (a) the aggregate amount of all

A-77

Registration Expenses incurred in connection with such registration and (b) the ratio that the number of such Registrable Securities bears to the total number of Registrable Securities included in the registration.

4.2 Holdback Agreements. Each Stockholder agrees not to effect any public sale or distribution of any Registrable Securities being registered or of any securities convertible into or exchangeable or exercisable for such Registrable Securities, including a sale pursuant to Rule 144 under the Act, during the ninety (90) day period beginning on the effective date of any Demand Registration or Incidental Registration or other underwritten offering in which such Stockholder is participating (except as part of such registration), if and to the extent requested by any other Stockholders, in the case of a non-underwritten public offering, or if and to the extent requested by the Approved Underwriter or Company Underwriter, in the case of an underwritten public offering.

5. Registration Procedures.

In connection with any registration statement filed pursuant to this Agreement, the Company will, as expeditiously as possible:

(a) in connection with a request pursuant to this Agreement, prepare and file with the Commission, after receipt of a request to file a registration statement with respect to Registrable Securities, a registration statement on any form for which the Company then qualifies or which counsel for the Company shall deem appropriate and which form shall be available for the sale of such Registrable Securities in accordance with the intended method of distribution thereof and, if the offering is an underwritten offering, shall be reasonably satisfactory to the managing underwriter or underwriters, and use its best efforts to cause such registration statement to become effective; provided, however, that before filing a registration statement or prospectus or any amendments or supplements thereto, the Company shall (i) furnish to the counsel selected by the Stockholder or Stockholders making the demand, if any, copies of all such documents proposed to be filed, and (ii) notify such counsel and each seller or prospective seller of Registrable Securities of any stop order issued or threatened by the Commission and take all reasonable actions required to prevent the entry of such stop order or to remove it if entered;

(b) in connection with a registration pursuant to this Agreement, prepare and file with the Commission such amendments and supplements to such registration statement and the prospectus used in connection therewith as may be necessary to keep such registration statement effective for a period of not more than one hundred twenty (120) days (or such shorter period that will terminate when all Registrable Securities covered by such registration statement have been disposed of);

(c) furnish to each seller of Registrable Securities such number of copies of the registration statement, each amendment and supplement thereto (in each case including all exhibits thereto), the prospectus included in such registration statement (including each preliminary prospectus) and such other documents as each seller

A-78

may reasonably request in order to facilitate the disposition of the Registrable Securities owned by such seller;

(d) use reasonable efforts to register or qualify such Registrable Securities under such other securities or "blue sky" laws of such jurisdictions as any seller or underwriter reasonably requests in writing and to do any and all other acts and things that may be reasonably necessary or advisable to register or qualify for sale in such jurisdictions the Registrable Securities owned by such seller; provided, however, that the Company shall not be required to (i) qualify generally to do business in any jurisdiction where it is not then so qualified, (ii) subject itself to taxation in any such jurisdiction, (iii) consent to general service of process in any such jurisdiction or (iv) provide any undertaking required by such other securities or "blue sky" laws or make any change in its charter or by-laws that the Board of Directors of the Company determines in good faith to be contrary to the best interest of the Company and its stockholders;

(e) use reasonable efforts to cause the Registrable Securities covered by such registration statement to be registered with or approved by such other governmental agencies or authorities as may be necessary by virtue of the business and operations of the Company to enable the seller or sellers thereof or the underwriters, if any, to consummate the disposition of such Registrable Securities;

(f) notify each seller of such Registrable Securities at any time when a prospectus relating thereto is required to be delivered under the Securities Act of the happening of any event as a result of which the prospectus included in such registration statement contains an untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, and prepare and file with the Commission as soon thereafter as practicable, after consultation with the Initiating Stockholders, a supplement or amendment to such prospectus so that, as thereafter delivered to the purchasers of such Registrable Securities, such prospectus will not contain an untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading;

(g) enter into customary agreements (including an underwriting agreement in customary form, if the offering is an underwritten offering) and take such other actions as are reasonably required in order to expedite or facilitate the disposition of such Registrable Securities;

(h) otherwise use reasonable efforts to comply with all applicable rules and regulations of the Commission; and

(i) use reasonable efforts to cause all Registrable Securities covered by the registration statement to be listed on each securities exchange or market, if any, on which similar securities issued by the Company are then listed, provided that the applicable listing requirements are satisfied.

A-79

The Company may require each seller or prospective seller of Registrable Securities as to which any registration is being effected to furnish to the Company such information regarding the distribution of such securities and other matters as may be required to be included in the registration statement.

Each holder of Registrable Securities agrees that, upon receipt of any notice from the Company of the happening of any event of the kind described in paragraph (f) of this Section 5, such holder shall forthwith discontinue disposition of Registrable Securities pursuant to the registration statement covering such Registrable Securities until such holder's receipt of the copies of the supplemented or amended prospectus contemplated by paragraph (f) of this
Section 5 and, if so directed by the Company, such holder shall deliver to the Company all copies, other than permanent file copies then in such holder's possession or copies delivered to prospective purchasers, of the prospectus covering such Registrable Securities current at the time of receipt of such notice. If the Company shall give any such notice, the Company shall extend the period during which such registration statement shall be maintained effective pursuant to this Agreement (including the period referred to in paragraph (b) of this Section 5) by the number of days during the period from and including the date of the giving of such notice pursuant to paragraph (f) of this Section 5 to and including the date when each seller of Registrable Securities covered by such registration statement shall have received the copies of the supplemented or amended prospectus contemplated by paragraph (f) of this Section 5.

A-80

alleged omission to state a material fact required to be stated therein or necessary to make the statements therein in light of the circumstances in which they were made not misleading, or any violation by the Company of the Securities Act or any rule or regulation thereunder applicable to the Company; provided, however, that the Company shall not be liable to the extent that any loss, claim, or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in such registration statement, any such preliminary prospectus, final prospectus, summary prospectus, amendment or supplement in reliance upon and in conformity with written information furnished to the Company by or on behalf of such Indemnified Party expressly for use in the Registration Statement; provided, further, that the Company shall not be liable to any seller of Registrable Securities (or to any person who acts as an underwriter in such sale or who controls such seller) to the extent that any loss, claim, or liability arises out of an untrue statement, alleged untrue statement, omission, or alleged omission made in any preliminary prospectus if either (a)(i) such seller failed to send or deliver a copy of the prospectus with or prior to written confirmation of the sale by such seller to the person asserting the claim and (ii) the prospectus would have corrected such untrue statement, alleged untrue statement, omission or alleged omission; or (b)(x) such untrue statement, alleged untrue statement, omission or alleged omission is corrected in an amendment or supplement to the prospectus and (y) having been furnished by or on behalf of the Company with copies of the prospectus as so amended or supplemented, such seller fails to deliver such prospectus as so amended or supplemented, with or prior to the written confirmation of the sale by such seller to the person asserting the claim.

7.2 Indemnification by Stockholders. In connection with any registration statement in which a Stockholder is participating, each such Stockholder shall furnish to the Company in writing such information and affidavits with respect to such Stockholder as the Company reasonably requests for use in connection with any such registration statement or prospectus and agrees to indemnify, to the fullest extent permitted by law, the Company, its officers, directors and agents and each person, if any, who controls the Company (within the meaning of the Securities Act) against any and all losses, claims, damages, and liabilities resulting from any untrue or alleged untrue statement of a material fact or any omission or alleged omission of a material fact required to be stated in any registration statement, prospectus or preliminary prospectus or any amendment thereof or supplement thereto or necessary to make the statements therein (in the case of a prospectus, in light of the circumstances under which they were made) not misleading, to the extent that such untrue or alleged untrue statement or omission is contained in or omitted from, as the case may be, any information or affidavit with respect to such Stockholder so furnished in writing by such Stockholder expressly for use in any such prospectus or preliminary prospectus; provided, however, that the liability of such Stockholder shall not exceed the net proceeds received by such Stockholder from the sale of its Registrable Securities. Each Stockholder also shall indemnify any underwriters of the Registrable Securities, their officers and directors and each

A-81

person who controls such underwriters (within the meaning of the Securities Act) to the same extent as provided above with respect to the indemnification of the Company; provided, however, that the indemnification of such Stockholder shall be limited to the net proceeds received by such Stockholder from the sale of its Registrable Securities.

7.3 Contribution. If the indemnification provided for in this Section 7 is unavailable to any Indemnified Party hereunder in respect of any losses, claims, damages, liabilities or expenses referred to herein, then the indemnifying party, to the extent such indemnification is unavailable, in lieu of indemnifying such Indemnified Party, shall contribute to the amount paid or payable by such Indemnified Party as a result of such losses, claims, damages, liabilities or expenses in such proportion as is appropriate to reflect the relative fault of the indemnifying party and Indemnified Parties in connection with the actions that resulted in such losses, claims, damages, liabilities or expenses. The relative fault of such indemnifying party and Indemnified Parties shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact, has been made by, or relates to information supplied by, such indemnifying party or Indemnified Parties, and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such action.

The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 7.3 were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to in the immediately preceding paragraph. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person.

NOW, THEREFORE, in consideration of the premises and of the mutual agreements, provisions and covenants herein contained, each Stockholder and the Company hereby agree as follows:

Section 1. Covenants of Stockholders with Respect to Voting Securities of the Company.

During the term of this Agreement and subject to all of the provisions hereof, each Stockholder and the Company agree as follows:

1.1 Acquisition of Voting Securities. Each Stockholder shall not acquire, agree to acquire or offer or propose to acquire, directly or indirectly, or in conjunction with or through any Person, record or beneficial ownership of any Voting Securities (as hereinafter defined), except (i) through the exercise of conversion rights, if any, of Voting Securities; (ii) by way of stock splits, reclassifications or stock dividends or other distributions or offerings made on a pro rata basis to holders of Voting Securities or any class of Voting Securities; (iii) from another Stockholder by bequest (including, without limitation, through the creation of a trust), gift, will, pledge, hypothecation or otherwise in accordance with clause (i) of Section 1.6 hereof; (iv) pursuant to a bequest or similar gift or transfer from a Person who is not a Stockholder, including, without limitation, through the creation of a trust for the benefit of a Stockholder; (v) pursuant to a will or the laws of descent and distribution from a Person who is not a Stockholder; or (vi) pursuant to the exercise of stock options or the receipt of other compensation or benefits involving Voting Securities granted to a Stockholder in such Stockholder's

A-88

capacity (if applicable) as an employee of the Company or any subsidiary of the Company; provided, however, that if, in connection with the transfer of Voting Securities to a Stockholder pursuant to clauses (iv) and (v) of this Section 1.1, a trust, corporation or other entity is formed for the purpose of holding Voting Securities for the benefit of a Stockholder (other than solely as an income beneficiary of a trust), then, as a condition precedent to the receipt by such Stockholder of any direct or indirect beneficial interest in such Voting Securities, such trust, corporation or other entity shall agree to be bound by the terms and conditions of a stockholder agreement having the same or substantially the same terms and conditions as this Agreement.

If a Stockholder shall acquire, directly or indirectly, record or beneficial ownership of, or the right to acquire, any Voting Securities in contravention of this Agreement, then such Stockholder shall promptly notify the Company, and the Company, in its sole discretion, may either (x) purchase (or cause its designee(s) to purchase) any or all of such acquired Voting Securities at a price equal to the price paid by such Stockholder or (y) require such Stockholder to dispose of, within 30 days from the date on which the Company requests such Stockholder to do so, only in accordance with the provisions of
Section 1.6 (ii) or (iv), the Voting Securities acquired in violation of this

Each Stockholder hereby acknowledges that any acquisition of Voting Securities in contravention of this Agreement shall constitute a breach of this Agreement and that the Company's right to purchase or require the disposition of Voting Securities pursuant to this Section 1.1 shall not be exclusive and shall be in addition to any other rights and remedies the Company may have in connection with a breach of this Agreement.

Each Stockholder shall vote or direct the vote of all Shares of Voting Securities that are (a) acquired pursuant to the Merger, (b) acquired by a Stockholder pursuant to Section 1.1, (c) held in trusts, corporations or other entities formed as contemplated by Section 1.6 or
(d) otherwise hereinafter acquired, with respect to which such Stockholder has the legal capacity to vote or to direct the vote of such Voting Securities, on each matter submitted to a vote of the stockholders of the Company, (x) in the same proportion as the votes cast by all holders of Voting Securities other than the Stockholders and any affiliates and associates of the Company, with respect to such matter, or, (y) in the event of a proposed change of control transaction for the Company, in the manner recommended to the stockholders by

A-89

(iv) be made to such Person if, immediately after such transaction, such Person (based upon the written representation of such Person, which as a condition precedent to such sale, transfer or other disposition shall be delivered to such Stockholder and to the Company prior to the consummation of such transaction), together with its affiliates and associates would be the direct or indirect beneficial or record owner of Voting Securities (when added to the Voting Securities (if any) already beneficially owned by such Person and its affiliates and associates) representing in excess of 5% of the Total Voting Power; (v) pursuant to a will or the laws of descent and distribution; provided, that the estate of a Stockholder shall be bound by the terms and conditions of this Agreement and if, immediately after any distribution out of such estate, any distributee, together with such distributee's affiliates and associates would (other than solely as an income beneficiary of a trust) be the direct or indirect beneficial or record owner of, or have the right to acquire, Voting Securities (when added to the Voting Securities (if any) already owned by such distributee and his/her affiliates and associates representing in excess of 5% of the Total Voting Power, then such distributee shall, as a condition precedent to receiving such shares of Voting Securities, agree to be bound by the terms and conditions of a stockholder agreement having the same terms and conditions as this Agreement; (vi) pursuant to a bequest or similar gift or transfer to any Person who is not a Stockholder or; provided that if, immediately after delivery of a bequest or similar gift or transfer, including, but not limited to, through the creation of a trust, the recipient, together with such recipient's affiliates and associates (including, as the case may be, the Stockholder making such transfer), would (other than solely as an income beneficiary of a trust) be the direct or indirect beneficial or record owner of, or have the right to acquire, Voting Securities (when added to the Voting Securities (if any) already owned

A-91

by such recipient and its affiliates and associates (including, as the case may be, the Stockholder making such transfer)) representing in excess of 5% of the Total Voting Power, then such recipient shall, as a condition precedent to receiving such shares of Voting Securities, agree to be bound by the terms and conditions of a stockholder agreement having the same terms and conditions as this Agreement; or (vii) as a result of any pledge or hypothecation to a bona fide financial institution to secure a bona fide loan, guaranty or other financial accommodation or as a result of any foreclosure with respect thereto; provided, however, that in connection with any transfer by a Stockholder of Voting Securities pursuant to clauses (v) or (vi) of this Section 1.6 to a trust, corporation or other entity and a Stockholder retains the authority, as trustee or otherwise, to vote, acquire or dispose of, or to direct the voting, acquisition or disposition of, Voting Securities to be held by such trust or other entity, then as a condition precedent to the transfer of such shares of Voting Securities to such trust or other entity, such Stockholder shall cause such trust or other entity to be bound by the terms and conditions of a stockholder agreement having the same or substantially the same terms and conditions as this Agreement.

Notwithstanding anything to the contrary contained herein, a Stockholder shall not dispose of or otherwise transfer any Voting Securities in violation of the provisions of Section 5 of the Securities Act.

1.7 No Solicitation. No Stockholder shall propose, solicit or participate in any fashion, in any transaction relating to an acquisition of, a business combination or similar transaction with, or a change of control of, the Company or make or solicit or encourage any Person to make a tender offer for Voting Securities.

1.8 Legend on Voting Securities. Each Stockholder agrees that each certificate representing its Voting Securities shall bear the following legend, which will remain thereon as long as such Voting Securities are subject to the restrictions contained in this Agreement:

The shares represented by this certificate are subject to the provisions of a Stockholder Agreement dated as of , 2000, among the Company and certain Stockholders, and may not be sold or transferred except in accordance therewith. Copies of said Agreement are on file at the offices of the Secretary of the Company.

The Company may enter a stop transfer order with the transfer agent (or agents) and the registrar (or registrars) of the Voting Securities against the transfer of legended Voting Securities held by a Stockholder except in compliance with the requirements of this Agreement. The Company agrees to remove promptly any stop transfer order with respect to, and issue promptly either legended (if the Voting Securities remain subject to the restrictions of this Agreement) or unlegended certificates in substitution for, certificates for any such Voting Securities that are no longer subject to or are to be transferred in compliance with the restrictions contained in this Agreement. Without limiting the generality of the foregoing, the Company shall promptly remove any stop transfer order in effect with respect to such certificates, upon the delivery to the Company of an opinion of counsel to a Stockholder, in form and substance reasonably

A-92

satisfactory to the Company, that legended certificates representing Voting Securities are no longer subject to this Agreement or that such Voting Securities are being transferred in compliance with the provisions of Sections 1.6, and shall promptly issue unlegended certificates in substitution for such legended certificates, except if such legended certificates are being transferred pursuant to Section 1.6 to a transferee who shall be bound by the terms and conditions of a Stockholder Agreement, in which event the Company may issue legended certificates.

RECAPITALIZATION AGREEMENT AND PLAN OF MERGER

RECAPITALIZATION AGREEMENT AND PLAN OF MERGER, dated as of March 9, 2000, by and among ATX Telecommunications Services, Inc., a Delaware corporation ("ATX"), CoreComm Limited, a Bermuda corporation ("CoreComm"), Thomas Gravina ("Gravina"), Debra Buruchian ("Buruchian"), Michael Karp ("Karp") and The Florence Karp Trust (the "Karp Trust" and, collectively with Gravina, Buruchian and Karp, the "ATX Stockholders").

RECITALS

WHEREAS, the Boards of Directors of ATX, and CoreComm, respectively, deem it advisable and in the best interests of ATX, CoreComm and their respective stockholders that ATX and CoreComm combine in order to advance the long-term business interests of ATX and CoreComm;

WHEREAS, the combination of ATX and CoreComm shall be effected by the terms of this Recapitalization Agreement and Plan of Merger (the "Agreement") through the Merger (of CoreComm Merger Sub (as defined herein) and ATX Merger Sub (as defined herein)) and the Recapitalization (each as defined herein) of ATX; and

WHEREAS, for federal income tax purposes, it is intended that the Merger and Recapitalization shall qualify as exchanges within the meaning of Section 351 of the Internal Revenue Code of 1986, as amended (the "Code") and as reorganizations within the meaning of Section 368(a) of the Code.

WHEREAS, the Boards of Directors of ATX and CoreComm have approved this Agreement and each of the documents required to be executed in connection with this Agreement to which it is a party.

Accordingly, in consideration of the representations, warranties, covenants and agreements contained herein, and intending to be legally bound hereby, the parties hereto agree as follows:

I. THE MERGER

1.1 The Formation of ATX Merger Sub, CoreComm Merger Sub and the Merger.

(a) As promptly as practicable following the execution of this Agreement, ATX shall cause to be organized for the sole purpose of effectuating the Merger contemplated herein a corporation organized under the laws of the State of Delaware ("ATX Merger Sub"). As promptly as practicable following the execution of this Agreement, CoreComm shall cause to be organized for the sole purpose of effecting the Domestication Merger (as defined in Section 1.1(d) below) and the Merger contemplated herein, a corporation organized under the laws of the State of Delaware ("CoreComm Merger Sub"). The respective certificates of incorporation and Bylaws of each of ATX Merger Sub and CoreComm Merger Sub shall be in such forms as shall be mutually determined by ATX and CoreComm as soon as practicable following the execution of this Agreement and the authorized capital stock of each of ATX Merger

B-6

Sub and CoreComm Merger Sub shall initially consist of 100 shares of common stock, par value $0.01 per share. All of the outstanding shares of ATX Merger Sub shall be issued to ATX at a price of $1.00 per share and all of the outstanding shares of CoreComm Merger Sub shall be issued to CoreComm at a price of $1.00 per share.

(b) As promptly as practicable following the execution of this Agreement, ATX (with respect to ATX Merger Sub) and CoreComm (with respect to CoreComm Merger Sub) shall take all requisite action to designate the directors and officers of ATX Merger Sub and CoreComm Merger Sub and take such steps as may be necessary or appropriate to complete the organization of ATX Merger Sub and CoreComm Merger Sub. ATX shall cause the directors of ATX Merger Sub to ratify and approve this Agreement. CoreComm shall cause the directors of CoreComm Merger Sub to ratify and approve this Agreement.

(c) As promptly as practicable following the organization of ATX Merger Sub, ATX, as the sole stockholder of ATX Merger Sub, shall cause ATX Merger Sub to adopt this Agreement and to perform its obligations under this Agreement. As promptly as practicable following the organization of CoreComm Merger Sub, CoreComm, as the sole stockholder of CoreComm Merger Sub shall cause CoreComm Merger Sub to adopt this Agreement and to perform its obligations under this Agreement. As promptly as practicable after the organization of ATX Merger Sub and CoreComm Merger Sub, the parties shall cause this Agreement to be amended to add ATX Merger Sub and CoreComm Merger Sub as parties hereto. Such amendment shall provide for the making by ATX Merger Sub of those representations and warranties equivalent to those set forth in Article 3 hereof that apply to ATX Merger Sub, and covenants and obligations equivalent to those set forth in Article 5 hereof that apply to ATX Merger Sub, and ATX Merger Sub and CoreComm Merger Sub shall each become a constituent corporation in the Merger.

(d) Immediately prior to the Merger, CoreComm shall amalgamate and merge with and into CoreComm Merger Sub (the "Domestication Merger"), subject to compliance with applicable provisions of the Delaware General Corporation Law (the "DGCL") and the laws of Bermuda. As a result of the Domestication Merger, each issued and outstanding share of CoreComm Common Stock shall become and represent one share of common stock, par value $.01 per share ("CoreComm Merger Sub Common Stock"), of CoreComm Merger Sub, and the independent existence of CoreComm shall cease. Prior to the consummation of the Domestication Merger, CoreComm, as sole stockholder of CoreComm Merger Sub, shall adopt this Agreement. Unless the context otherwise requires, all references in this Agreement to CoreComm shall be deemed to mean CoreComm prior to the consummation of the Domestication Merger and CoreComm Merger Sub following the consummation of the Domestication Merger, and all references to CoreComm Common Stock shall be deemed to mean the CoreComm Common Stock prior to the consummation of the Domestication Merger and CoreComm Merger Sub Common Stock after the consummation of the Domestication Merger.

B-7

(e) Subject to the provisions of this Agreement, a certificate of merger (the "Certificate of Merger") in such form as is required by the relevant provisions of the DGCL shall be duly prepared, executed and acknowledged by the appropriate parties and thereafter delivered to the Secretary of State of the State of Delaware for filing, as provided in the DGCL, on the Closing Date (as defined in Section 2.1). The Merger shall become effective upon the filing of the Certificate of Merger with the Secretary of State of the State of Delaware (the "Effective Time").

(f) At the Effective Time, the separate existence of ATX Merger Sub shall cease and ATX Merger Sub shall be merged (the "Merger") with and into CoreComm Merger Sub (ATX Merger Sub and CoreComm Merger Sub are sometimes referred to herein as the "Constituent Corporations" and CoreComm Merger Sub is sometimes referred to herein as the "Surviving Corporation"). The Certificate of Incorporation of CoreComm Merger Sub as in effect immediately prior to the Effective Time shall be the Certificate of Incorporation of the Surviving Corporation until thereafter amended as provided by the DGCL, the Bylaws of CoreComm Merger Sub as in effect immediately prior to the Effective Time shall be the Bylaws of the Surviving Corporation until thereafter amended as provided by the DGCL, the Certificate of Incorporation and such Bylaws.

(g) At and after the Effective Time, the effect of the Merger shall be as provided in the applicable provisions of the DGCL. Without limiting the generality of the foregoing, and subject thereto, the Surviving Corporation shall possess all the rights, privileges, powers and franchises of a public as well as of a private nature, and be subject to all the restrictions, disabilities and duties of each of the Constituent Corporations; and all and singular rights, privileges, powers and franchises of each of the Constituent Corporations, and all property, real, personal and mixed, and all debts due to either of the Constituent Corporations on whatever account, as well as for stock subscriptions and all other things in action or belonging to each of the Constituent Corporations, shall be vested in the Surviving Corporation, and all property, rights, privileges, powers and franchises, and all and every other interest shall be thereafter the property of the Surviving Corporation as they were of the Constituent Corporations, and the title to any real estate vested by deed or otherwise, in either of the Constituent Corporations, shall not revert or be in any way impaired; but all rights of creditors and all liens upon any property of either of the Constituent Corporations shall be preserved unimpaired, and all debts, liabilities and duties of the Constituent Corporations shall thereafter attach to the Surviving Corporation, and may be enforced against it to the same extent as if such debts and liabilities had been incurred by it.

1.2 The Recapitalization.

(a) Simultaneously with the Merger, ATX shall recapitalize (the "Recapitalization") by causing the ATX Stockholders to exchange, and the ATX Stockholders agree to exchange, all of the issued and outstanding shares of pre-Recapitalization ATX

B-8

common stock, par value $.01 per share ("ATX Common Stock") for the following aggregate consideration:

(i) That number of shares of ATX Common Stock equal to $500 million divided by the Base Stock Price. The "Base Stock Price" shall be equal to $40.328, subject to the Base Adjustments as defined below.

The number of shares of ATX Common Stock to be received by the ATX Stockholders in connection with the Recapitalization will be subject to a collar mechanism as follows: in the event that the volume weighted average trading price of CoreComm Common Stock for the ten trading days ending with the last trading day prior to the Closing Date (the "Closing Stock Price") is greater than the Collar Stock Price (as defined below), then the number of shares of ATX Common Stock to be issued to the ATX Stockholders pursuant to the Recapitalization will be adjusted such that the aggregate value (based on the Closing Stock Price) of the ATX Common Stock received by the ATX Stockholders is equal to the aggregate value (based on the Closing Stock Price) of ATX Common Stock they would have been entitled to receive if the Closing Stock Price were equal to the Collar Stock Price.

The "Collar Stock Price" shall be the Base Stock Price multiplied by the Collar Percentage. The Collar Percentage shall be equal to 115%, subject to the following adjustments: If (1) the Closing has not occurred on or prior to July 15, 2000, (2) subsequent to the date of this Agreement, CoreComm has engaged in a transaction (other than transactions contemplated by this Agreement, which shall not be deemed to include the potential transaction referred to in Section 5.18 or any transaction which would result in a Base Adjustment) (a "CoreComm Transaction") that would (x) require the approval of the stockholders of CoreComm or, (y) require CoreComm to include the information relating to such transaction in the pro forma financial statements (the "Pro Formas") that are required to be contained in the Registration Statement or (z) require CoreComm to amend or restate the Pro Formas in any material manner, and (3) all conditions to Closing have been satisfied (or waived by the party entitled to waive such condition) or are capable of being satisfied on such date with reasonable best efforts, other than the conditions set forth in Sections 6.10 and/or 6.11, and the failure of either such condition to be satisfied is the direct result of a CoreComm Transaction, then, commencing on the later to occur of (i) July 16, 2000 and (ii) the first business day after which the circumstances set forth in clause (3) are present (such later date being the "Trigger Day") the Collar Percentage shall be increased as follows: 2.5 percentage points on the Trigger Day, and an additional five percentage points per each 31 day period (a "Monthly Period") (on a pro rata basis, based on the actual number of elapsed days in such Monthly Period at the Closing Date) beginning on the sixteenth calendar day following the Trigger Day. An example of this calculation is set forth on Exhibit J.

The "Base Adjustments" shall be as follows: (i) if, after the date of this Agreement and on or prior to the Closing Date the outstanding shares of CoreComm Common Stock shall be changed into a different number of shares by reason of any reclassification, recapitalization, stock split, reverse stock split, combination or exchange

B-9

of shares, or any dividend payable in CoreComm Common Stock shall be declared thereon with a record date within such period, or any similar event shall occur, the Base Stock Price shall be adjusted accordingly to provide to the ATX Stockholders the same economic effect as contemplated by this Agreement prior to such reclassification, recapitalization, stock split, reverse stock split, combination, exchange, dividend or similar event; and (ii) if, after the date of this Agreement and on or prior to the Closing Date, CoreComm shall distribute to all holders of CoreComm Common Stock shares of capital stock of CoreComm other than CoreComm Common Stock, evidences of indebtedness or other assets (other than cash dividends out of current or retained earnings), or shall distribute to substantially all holders of Common Stock rights or warrants to subscribe for securities (other than those referred to in subsection (i) above), then in each such case the Base Stock Price shall be multiplied by a fraction of which the numerator shall be the Current Market Price (as defined below) of the CoreComm Common Stock on the record date less the then fair market value (as determined by the CoreComm Board of Directors, whose determination shall be conclusive evidence of such fair market value (absent manifest error) and described in a board resolution) of the portion of the assets so distributed or of such subscription rights or warrants applicable to one share of CoreComm Common Stock and of which the denominator shall be the Current Market Price of the CoreComm Common Stock. The "Current Market Price" shall mean the volume weighted average trading price of CoreComm Common Stock for the ten prior trading days. CoreComm may only effect a distribution described under (ii) above, if such distribution does not include operating assets that are required to maintain the current operating businesses of CoreComm, Inc. (a subsidiary of CoreComm), other than the local multipoint distribution service licenses and related assets.

(ii) 250,000 shares of ATX Series 3% Senior Convertible Exchangeable Preferred Stock, par value $.01 per share ("ATX Convertible Preferred Stock"), with such rights and preferences as set forth in the term sheet attached hereto as Exhibit A setting forth the terms and conditions of the ATX Convertible Preferred Stock; and

(iii) $150 million in cash (the "Cash Consideration") (subject to certain adjustments set forth herein) (collectively with the ATX Common Stock and the ATX Convertible Preferred Stock, the "Exchange Consideration"); provided, however, that in the event CoreComm has not completed a debt or equity financing (including a public or private sale of equity securities or an institutional debt financing) prior to the Closing Date, at CoreComm's election, the aggregate amount of Cash Consideration to be paid by CoreComm to the ATX Stockholders may be reduced by up to $70 million and such portion of the Cash Consideration shall be paid through the issuance of short term senior notes with such terms and conditions as set forth in the term sheet attached hereto as Exhibit B.

(b) ATX shall prepare as of a date not more than five (5) business days prior to the Closing Date, an unaudited consolidated balance sheet (estimated as of the Closing Date) and unaudited statements of income and cash flows of ATX for the period from the ATX Balance Sheet Date to the date of such statements (the "Pre-Closing Financial Statements") from the GAAP Audited Financials and the books and records of ATX in

B-10

accordance with GAAP (applied on a consistent basis using the same accounting methods, policies, practices, principles and procedures with consistent classifications, judgments and estimation methodologies used in preparation of the GAAP Audited Financials) and shall set forth the Working Capital ("Estimated Closing Working Capital"), the ATX Debt (the "Estimated Closing ATX Debt") and the estimated capital expenditures made by ATX during such period (the "Estimated Closing Capital Expenditures"). To the extent ATX intends to make distributions at Closing as permitted by Section 1.2(j), such intended distributions shall be included in the Pre-Closing Financial Statements on a pro-forma basis. ATX shall provide a copy of the Pre-Closing Financial Statements to CoreComm within three (3) days of its completion.

In the event that the Pre-Closing Financial Statements reflect that the Estimated Closing Working Capital is less than zero (such deficiency, the "Working Capital Shortfall"), then the Exchange Consideration shall be reduced (subject to the calculation of the Final Closing Financial Statements) by an amount equal to the excess of zero over the Estimated Closing Working Capital. If the Pre-Closing Financial Statements reflect that the Estimated Closing Working Capital is greater than zero (such excess, the "Working Capital Excess") then the Exchange Consideration shall be increased (subject to the calculation of the Final Closing Financial Statements) by an amount equal to the amount of the Working Capital Excess. The Working Capital Shortfall or Working Capital Excess, as applicable, shall be the "Pre-Closing Working Capital Adjustment."

In the event that the Pre-Closing Financial Statements reflect that Estimated Closing ATX Debt is greater than zero, then the Exchange Consideration shall be reduced (subject to the calculation of the Final Closing Financial Statements) by an amount equal to the Estimated Closing ATX Debt.

In the event that the Pre-Closing Financial Statements reflect that the Capital Expenditure Adjustment, as calculated using the Estimated Closing Capital Expenditures from the Pre-Closing Financial Statements, is greater than zero (such amount, the "Pre-Closing Capital Expenditure Adjustment"), then the Exchange Consideration shall be reduced (subject to a calculation of the final Closing Financial Statements) by an amount equal to the Pre-Closing Capital Expenditure Adjustment.

(c) Within ninety (90) days after the Closing Date (the "Closing Financial Statements Delivery Date"), ATX shall cause to be prepared and delivered to the Stockholder Representative (as defined below) a proposed unaudited balance sheet and proposed unaudited statements of income and cash flows (the "Proposed Closing Financial Statements") prepared in accordance with GAAP (applied on a consistent basis using the same accounting methods, policies, practices, principles and procedures with consistent classifications, judgments and estimation methodologies that were used in preparation of the GAAP Audited Financials) setting forth the Working Capital of ATX and ATX Debt as of the Closing Date and Capital Expenditures of ATX for the period from the ATX Balance Sheet Date through the Closing Date. For purposes of this Section 1.2, the Stockholder Representative shall mean BDO Seidman, LLP.

(d) The Stockholder Representative shall have a period of thirty (30) days (the "Review Period") from the date on which ATX delivers the Proposed Closing Financial Statements to the Stockholder Representative pursuant to Section 1.2(c), to review the Proposed Closing Financial Statements. If, prior to the expiration of the Review Period, the Stockholder Representative does not deliver a Dispute Notice (as defined below) to ATX, the unaudited balance sheet and unaudited statements of income and cash flows included in the Proposed Closing Financial Statements shall be deemed to be final and binding upon ATX and the ATX Stockholders for purposes of determining the Working Capital of ATX and the ATX Debt as of the Closing Date and the Capital Expenditures of ATX for the period from the ATX Balance Sheet Date through the Closing Date for purposes of this Agreement. The unaudited balance sheet and unaudited statements of income and cash flows included in the Proposed Closing Financial Statements shall not become final and binding at the end of the Review Period if, prior to the expiration of the Review Period, the Stockholder Representative delivers a written notice to ATX (the "Dispute Notice") setting forth in reasonable detail the disagreements that the Stockholder Representative has with the unaudited balance sheet and/or either of the unaudited statements of income and cash flows included in the Proposed Closing Financial Statements and the effect which such disagreements would have on the calculation of any of the Working Capital of ATX and ATX Debt as of the Closing Date or Capital Expenditures of ATX for the period from the ATX Balance Sheet Date through the Closing Date. If the Stockholder Representative delivers a Dispute Notice prior to the end of the Review Period, the representatives of ATX and the Stockholder Representative shall have a ten (10) day period (the "Settlement Period") from the date of the delivery of the Dispute Notice to attempt to resolve any dispute set forth in the Dispute Notice and to agree upon an unaudited balance sheet and unaudited statements of income and cash flows which shall be binding on ATX and the ATX Stockholder for purposes of this Agreement and to agree upon the Working Capital of ATX and ATX Debt as of the Closing Date and the Capital Expenditures of ATX for the period from the ATX Balance Sheet Date through the Closing Date. If the Stockholder Representative and ATX have not arrived at an agreement during the Settlement Period then, at any time following the termination of the Settlement Period, either the Stockholder Representative or ATX may submit the issue in dispute to the Philadelphia, Pennsylvania office of PricewaterhouseCoopers LLP (the "Accountant") for resolution in accordance with this Section. In resolving any disputed item, the Accountant (i) shall be bound by the provisions of this
Section 1.2, (ii) may not assign a value to any item greater than the greatest value for such item claimed by either party or less than the smallest value for such item claimed by either party, (iii) shall make its determination based solely on information submitted by the parties and not by independent review and
(iv) shall be instructed to issue a report containing its resolution of the disputed issue or issues (the "Accountant's Report") within thirty (30) days following submission of the dispute. The Accountant's Report shall be delivered by the Accountant to ATX and the Stockholder Representative, and shall be final and binding on ATX and the ATX Stockholders for purposes of this Agreement. The fees charged by the Accountant shall be paid by ATX.

(e) During the period of any dispute within the contemplation of this
Section 1.2, the ATX Stockholders, the Stockholder Representative and their representatives (including counsel and accountants) shall have reasonable access during normal business hours to all books, records, employees, offices and other facilities and properties of the Surviving Corporation to the extent required to complete their review of the Closing Financial Statements and shall be permitted to review the working papers (subject to the execution of customary waivers, releases and indemnifications), if any, of ATX or its auditor relating to the Closing; provided that any such access shall not unreasonably interfere with the day-to-day operations of ATX and shall be limited to those items related to the assessment of the Closing Financial Statements and matters related thereto. ATX and CoreComm or their auditors shall cooperate with the ATX Stockholders and other representatives of the ATX Stockholders in facilitating such review.

(f) In the event that the Final Closing Financial Statements reflect that the Working Capital of ATX as of the Closing Date is less than the Applicable Amount (such deficiency, the "Final Working Capital Shortfall"), then an amount equal to the excess of the Applicable Amount over the Final Working Capital Shortfall shall be paid to ATX from the Escrow (defined below) as provided in Subsection 1.2(i) (the "Final Shortfall"); provided, however, that the Final Shortfall shall be adjusted to reflect any adjustments to the Closing Exchange Consideration previously made due to a Pre-Closing Working Capital Adjustment. If the Final Closing Balance Sheet reflects that the Working Capital of ATX as of the Closing Date is greater than the Applicable Amount (a "Final Working Capital Excess") then an amount equal to the excess of the Final Working Capital Excess over the amount of Working Capital generated subsequent to July 31, 2000 shall be delivered to the ATX Stockholders by ATX as provided in Subsection 1.2(i); provided, however, that the Final Working Capital Excess (and any related amounts to be paid) shall be adjusted to reflect any adjustments to the Closing Exchange Consideration previously made due to a Pre-Closing Working Capital Adjustment. As used herein, the "Applicable Amount" means $2,000,000, if the Closing occurs on or prior to July 31, 2000 and zero if the Closing occurs after July 31, 2000.

(g) In the event that the Final Closing Financial Statements reflect that the ATX Debt is greater than zero (such amount the "Final ATX Debt"), then an amount equal to the Final ATX Debt shall be paid to ATX from the Escrow as provided in Subsection 1.2(i); provided, however, that the Final ATX Debt shall be adjusted to reflect any adjustments to the Closing Exchange Consideration previously made due to any Estimated Closing ATX Debt.

(h) In the event that the Final Closing Financial Statements reflect that the Capital Expenditure Adjustment, as calculated utilizing the Capital Expenditures as set forth on the Final Closing Financial Statements, is greater than zero (the "Final Capital Expenditure Adjustment"), then the amount equal to the Final Capital Expenditure Adjustment shall be paid to ATX from the Escrow as provided in Subsection 1.2(i); provided, however, that the Final Capital Expenditure Adjustment shall be adjusted to

B-13

reflect adjustments to the Closing Exchange Consideration previously made due to a Pre-Closing Capital Expenditure Adjustment.

(i) Upon the Recapitalization, an aggregate of 1.1111% of all shares of ATX Common Stock, ATX Convertible Preferred Stock and Cash Consideration (provided that if any portion of the Cash Consideration is to be payable in Short Term Senior Notes, the Short Term Senior Notes shall be delivered prior to the Cash Consideration) comprising the Exchange Consideration shall be deposited in escrow (the "Escrow") pursuant to an escrow agreement among ATX, CoreComm, each ATX Stockholder and an escrow agent selected by such parties (the "Escrow Agreement"). In the event of any reduction in the Exchange Consideration requiring a repayment to ATX under Subsections (f) through (h) above, such repayment shall be made pro rata from the ATX Common Stock, ATX Convertible Preferred Stock and cash in the Escrow, for purposes of which the ATX Common Stock shall be valued at the closing price for ATX Common Stock on the trading day immediately preceding the day on which the repayment of such share to ATX is effected. Any amounts payable by ATX under Subsection (f) as additional Exchange Consideration shall be in shares of ATX Common Stock based on the same valuation as set forth in the preceding sentence subject to the right of any ATX Stockholders to elect to receive such additional Exchange Consideration in cash.

(j) From the ATX Balance Sheet Date through the Closing Date, ATX shall be permitted to:

(i) make such cash distributions and payments to the ATX Stockholders:
(x) in order to satisfy any debt obligation of ATX to the ATX Stockholder(s) (including affiliates thereof); (y) in order to return any capital to the ATX Stockholders (including the amount of any positive capital account balances respecting the ATX Partnerships) (as hereinafter defined); and (z) of any undistributed profits computed in accordance with GAAP of ATX or the ATX Partnership through the Closing Date; provided that if there is insufficient cash on hand to make such distributions and payments, the amounts shall be payable by ATX on the business day next following the Closing Date and the payment of such amounts shall be deemed to have been made on the business day prior to the Closing Date for purposes of the adjustments set forth in this Section 1.2; or (ii) cancel or eliminate any indebtedness owed by any ATX Stockholders to ATX.

(k) The following terms, whenever used herein, shall have the following meanings for all purposes of this Agreement:

"ATX Balance Sheet Date" means December 31, 1999.

"ATX Capital Expenditure Obligation" means the obligation of ATX and the ATX Partnerships to make Capital Expenditures from the period commencing January 1, 2000 through the Closing Date in the amount and for those categories of items set forth on Section 1.2 of the ATX Disclosure Schedule.

1.3 Conversion of CoreComm Common Stock. As of the Effective Time, by virtue of the Merger and without any action on the part of the holder of any shares of ATX Merger Sub's common stock, par value $.01 per share ("ATX Merger Sub Common Stock") or CoreComm's common stock, par value $.01 per share ("CoreComm Common Stock"):

(a) Each issued and outstanding share of ATX Merger Sub Common Stock shall be converted into the right to receive one (1) share of CoreComm Common Stock.

(b) All shares of CoreComm Common Stock that are owned by CoreComm as treasury stock or by any Subsidiary of CoreComm shall be canceled and retired and shall cease to exist and no consideration shall be delivered in exchange therefor. As used in this Agreement, the word "Subsidiary" means, with respect to any party, any corporation or other organization, whether incorporated or unincorporated, of which (i) such party or any other Subsidiary of such party is a general partner (excluding partnerships, the general partnership interests of which held by such party or any Subsidiary of such party do not have a majority of the voting interest in such partnership) or (ii) at least a majority of the securities or other interests having by their terms ordinary voting power to elect a majority of the Board of Directors or others performing similar functions with respect to such corporation or other organization is directly or indirectly owned or controlled by such party or by any one or more of its Subsidiaries, or by such party and one or more of its Subsidiaries.

(c) Subject to Section 1.4, each issued and outstanding share of CoreComm Common Stock (other than shares to be canceled in accordance with Sec-

B-15

tion 1.3(b) and shares to be issued under Section 1.3(a)) shall be converted into the right to receive one (1) (the "Merger Ratio") fully paid and nonassessable shares of ATX Common Stock. All such shares of CoreComm Common Stock, when so converted, shall no longer be outstanding and shall automatically be canceled and retired and shall cease to exist, and each holder of a certificate representing any such shares shall cease to have any rights with respect thereto, except the right to receive the shares of ATX Common Stock and any cash in lieu of fractional shares of ATX Common Stock to be issued or paid in consideration therefor upon the surrender of such certificate in accordance with Section 1.4.

1.4 Exchange of Certificates. The procedures for exchanging outstanding shares of CoreComm Common Stock for ATX Common Stock pursuant to the Merger shall be as follows:

(a) As of the Effective Time, ATX shall deposit with an exchange agent selected by CoreComm and reasonably acceptable to ATX (the "Exchange Agent"), for the benefit of the holders of shares of CoreComm Common Stock, certificates representing the shares of ATX Common Stock and cash (such shares of ATX Common Stock together with any dividends or distributions with respect thereto, together with such cash, being hereinafter referred to as the "Exchange Fund") issuable pursuant to Section 1.3 in exchange for outstanding shares of CoreComm Common Stock.

(b) Promptly after the Effective Time, the Exchange Agent shall mail to each holder of record of a certificate or certificates which immediately prior to the Effective Time represented outstanding shares of CoreComm Common Stock (each a "Certificate" and, collectively, the "Certificates") whose shares were converted pursuant to Section 1.4 into the right to receive shares of ATX Common Stock (i) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates to the Exchange Agent and shall be in such form and have such other provisions as ATX and CoreComm may reasonably specify) and (ii) instructions for use in effecting the surrender of the Certificates in exchange for certificates representing shares of ATX Common Stock. Upon surrender of a Certificate for cancellation to the Exchange Agent, together with such letter of transmittal, duly executed, the holder of such Certificate shall be entitled to receive in exchange therefor a certificate representing that number of whole shares of ATX Common Stock which such holder has the right to receive pursuant to the provisions of this Article 1, and the Certificate so surrendered shall immediately be canceled. In the event of a transfer of ownership of CoreComm Common Stock which is not registered in the transfer records of CoreComm, a certificate representing the proper number of shares of ATX Common Stock may be issued to a transferee if the Certificate representing such CoreComm Common Stock is presented to the Exchange Agent, accompanied by all documents required to evidence and effect such transfer and by evidence that any applicable stock transfer taxes have been paid. Until surrendered as contemplated by this Section 1.4, each Certificate shall

B-16

be deemed at any time after the Effective Time to represent only the right to receive upon such surrender the certificate representing shares of ATX Common Stock and cash in lieu of any fractional share as contemplated by this Section 1.4. All shares of ATX Common Stock issued upon the surrender for or exchange of Certificates in accordance with the terms of this Agreement, shall be deemed to have been issued in full satisfaction of all rights pertaining to the CoreComm Common Stock shares formerly represented by such Certificates. The instructions for effecting the surrender of the Certificates shall set forth procedures that must be taken by the holder of any Certificate that has been lost, destroyed or stolen. It shall be a condition to the right of such holder to receive a certificate representing shares of ATX Common Stock that the Exchange Agent shall have received, along with the letter of transmittal, a duly executed lost certificate affidavit, including an agreement to indemnify ATX, signed exactly as the name or names of the registered holder or holders appeared on the books of CoreComm immediately prior to the Effective Time, together with a customary bond and such other documents as ATX or the Exchange Agent may reasonably require in connection therewith.

(c) No dividends or other distributions declared or made after the Effective Time with respect to ATX Common Stock with a record date after the Effective Time shall be paid to the holder of any unsurrendered Certificate with respect to the shares of ATX Common Stock represented thereby and no cash payment in lieu of fractional shares shall be paid to any such holder pursuant to subsection (e) below until the holder of such Certificate shall surrender such Certificate. Subject to the effect of applicable laws, following surrender of any such Certificate, there shall be paid to the holder of the certificates representing whole shares of ATX Common Stock issued in exchange therefor, without interest, (i) at the time of such surrender, the amount of any cash payable in lieu of a fractional share of ATX Common Stock to which such holder is entitled pursuant to subsection (e) below and the amount of dividends or other distributions with a record date after the Effective Time previously paid with respect to such whole shares of ATX Common Stock, and (ii) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Effective Time but prior to surrender and a payment date subsequent to surrender payable with respect to such whole shares of ATX Common Stock.

(d) All shares of ATX Common Stock issued upon the surrender for exchange of shares of CoreComm Common Stock in accordance with the terms hereof (including any cash paid pursuant to subsection (c) or (e) of this
Section 1.4) shall be deemed to have been issued in full satisfaction of all rights pertaining to such shares of CoreComm Common Stock, subject, however, to the Surviving Corporation's obligation to pay any dividends or make any other distributions with a record date prior to the Effective Time which may have been declared or made by CoreComm on such shares of CoreComm Common Stock in accordance with the terms of this Agreement on or prior to the date hereof and which remain unpaid at the Effective Time, and there shall be no further registration of transfers on the stock transfer books of the Surviving Corporation of the shares of CoreComm

B-17

Common Stock which were outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates are presented to the Surviving Corporation for any reason, they shall be canceled and exchanged as provided in this Section 1.4.

(e) No certificate or scrip representing fractional shares of ATX Common Stock shall be issued upon the surrender for exchange of Certificates, and such fractional share interests will not entitle the owner thereof to vote or to exercise any rights of a stockholder of ATX. Notwithstanding any other provision of this Agreement, each holder of shares of CoreComm Common Stock exchanged pursuant to the Merger who would otherwise have been entitled to receive a fraction of a share of ATX Common Stock (after taking into account all Certificates delivered by such holder) shall receive, in lieu thereof, cash (without interest) in an amount equal to such fractional part of a share of ATX Common Stock multiplied by the last reported sale price of ATX Common Stock, as reported on The Nasdaq National Market, on the first trading day after the Effective Time.

(f) Any portion of the Exchange Fund which remains undistributed to the stockholders of CoreComm for one year after the Effective Time shall be delivered to ATX, and any former stockholders of CoreComm who have not previously complied with this Section 1.4 shall thereafter look only to ATX for payment of their claim for ATX Common Stock, any cash in lieu of fractional shares of ATX Common Stock, and any dividends or distributions with respect to CoreComm Common Stock or ATX Common Stock.

(g) Neither CoreComm nor ATX shall be liable to any former holder of shares of CoreComm Common Stock or current holder of ATX Common Stock, as the case may be, for such shares (or dividends or distributions with respect thereto) delivered to a public official as required by any applicable abandoned property, escheat or similar law.

1.5 Directors and Officers of Surviving Corporation. The initial directors of the Surviving Corporation shall be the directors of CoreComm immediately prior to the Merger, each to hold office in accordance with the Certificate of Incorporation and Bylaws of the Surviving Corporation, and the initial officers of the Surviving Corporation shall be the officers of CoreComm immediately prior to the Merger, in each case until their respective successors are duly elected or appointed.

(c) In furtherance and not in limitation of the covenants of the parties contained in this Section 5.7, if any administrative or judicial action or proceeding, including any proceeding by a private party, is instituted (or threatened to be instituted) challenging the transaction contemplated by this Agreement as violative of any Regulatory Law, each of the parties hereto shall cooperate in all respects with each other and contest and resist any such action or proceeding and use its respective reasonable best efforts to have vacated, lifted, reversed or overturned any decree, judgment, injunction or other order, whether temporary, preliminary or permanent, that is in effect and that prohibits, prevents or restricts consummation of the transaction contemplated by this Agreement.

(g) CoreComm shall have the right to have its designated representatives, as provided to ATX from time to time (the "Designated CoreComm Representatives"), present within normal business hours and without material disruption to the business of ATX for consultation at ATX's principal offices from the date hereof until the Closing Date. Such Designated CoreComm Representatives shall have the right to review and become familiar with the conduct of the business of ATX and shall be available to be

B-44

consulted and shall have authority on behalf of CoreComm in regard to consultation in regard to Material Decisions (as defined below in this Section 5.7(g)).

"Material Decision" shall mean, for purposes of this Agreement, any of the following to the extent the same may affect the assets, the obligations or the business of ATX following the date hereof: (i) any entering into, termination or material amendment of, or waiver of any ATX's rights in respect of, any material contracts; (ii) any purchase order in excess of $100,000 in any instance to be delivered, or the payment for which shall become due, after the Closing Date; (iii) the acceptance of any material customer contract that deviates from the terms and conditions of current pricing policies; (iv) any action to respond to any material customer or regulatory complaint outside of the ordinary course of business; (v) any general communication with customers related to the business or to the Merger; or (vi) a material change in pricing, promotional, marketing or any other decision that would affect any of ATX's customary profit margins.

5.9 Effect of Due Diligence. In connection with CoreComm's investigation of the business of ATX, CoreComm may have received from or on behalf of ATX certain projections, including projected statements of operating revenues and income from operations of ATX. CoreComm acknowledges that there are uncertainties inherent in attempting to make such estimates, projections and other forecasts and plans, that CoreComm is familiar with such uncertainties, that CoreComm is taking full responsibility for making its own evaluation of the adequacy and accuracy of all estimates, projections and other forecasts and plans so furnished to it (including the reasonableness of the assumptions underlying such estimates, projections and forecasts), and that CoreComm shall have no claim against ATX, or any of its Affiliates with respect thereto. Accordingly, ATX makes no representation or warranty with respect to such estimates, projections and other forecasts and plans (including the reasonableness of the assumptions underlying such estimates, projections and forecasts).

5.10 Letters from Accountants; New Financial Statements.

(a) CoreComm shall use its reasonable best efforts to cause to be delivered to ATX "cold comfort" letters of Ernst & Young LLP its independent public accountants, dated the date on which the Registration Statement shall become effective and as of the

(b) On or prior to March 15, 2000, ATX shall provide to CoreComm revised versions of the ATX Financial Statements and the revised ATX Balance Sheet, which will present the combined balance sheets of the ATX Partnerships at December 31, 1997, December 31, 1998 and December 31, 1999 and the related combined statements of income, shareholder's equity and changes in financial position for the years then ended, including the footnotes thereto, and shall be certified by BDO Seidman, LLP, and shall fairly present the consolidated financial position of ATX and/or the ATX Partnerships at such dates and the consolidated results of operations of the ATX Partnerships and their subsidiaries for such respective periods, in each case in accordance with generally accepted accounting principles consistently applied for the periods covered thereby.

Prior to the filing of the Registration Statement, ATX shall use its reasonable best efforts to cause its accountants to supply to CoreComm the GAAP Audited Financials.

(c) ATX shall use its reasonable best efforts to cause to be delivered to CoreComm "cold comfort" letters of BDO Seidman LLP, its independent public accountants, dated the date on which the Registration Statement shall become effective and as of the Effective Time, respectively, and addressed to CoreComm in form and substance reasonably satisfactory to CoreComm and comparable in scope and substance to letters customarily delivered by independent public accountants in connection with registration statements similar to the Registration Statement and transactions such as the transaction contemplated by this Agreement.

(d) ATX shall provide CoreComm with any and all further financial statements or information which is necessary or advisable to prepare or include in the Registration Statement.

5.11 Nasdaq Application. ATX shall promptly prepare and submit an application to The Nasdaq National Market to list the shares of ATX Common Stock to be issued in the Merger and the Recapitalization and shall use its best efforts to cause such shares of ATX Common Stock to be approved for listing by The Nasdaq National Market, subject to official notice of issuance, prior to the Closing Date.

5.12 Stock Plans and Options. CoreComm currently intends to implement a stock option plan under which award grants may be made to post-Effective Time employees of ATX and its subsidiaries, and that such post-Effective Time employees shall include persons who prior to the Effective Time were employees of ATX or its subsidiaries as well as of CoreComm or its subsidiaries; it being understood that (i) nothing set forth herein shall be deemed to grant to any specific employee of post-Effective Time ATX or its subsidiaries any right to receive an option grant under any such plan, and (ii) the decision as to whether or not any such plan shall be implemented, the terms of any such

B-46

stock option plan, and the terms of any grant made thereunder, shall be within the discretion of post-Effective Time ATX, its board of directors, and any committee of such board which may administer such plan.

5.13 Access and Investigations. Prior to the Closing Date, ATX agrees that CoreComm shall be entitled to, through its employees and representatives, including Paul, Weiss, Rifkind, Wharton & Garrison, and Ernst & Young LLP (collectively, their "Representatives"), to make such investigation of the properties, businesses and operations of ATX, and such examination of the books, records and financial condition of ATX, as it wishes. Any such investigation and examination shall be conducted at a reasonable time, upon reasonable advance notice and under reasonable circumstances and ATX shall cooperate fully therein; provided, however, that no such investigation or examination shall interfere with the day-to-day operations of ATX. No investigation by CoreComm shall diminish or obviate any of the representations, warranties, covenants or agreements of ATX contained in this Agreement. In order that CoreComm may have full opportunity to make such physical, business, accounting and legal review, examination or investigation as it may wish of the affairs of ATX, ATX shall make available to the Representatives during such period all such information and copies of documents concerning the affairs of ATX as the Representatives may reasonably request, and shall permit the Representatives access to the properties of ATX in all parts thereof.

5.14 Communications Licenses and Authorizations. ATX shall obtain and maintain in full force and effect all Permits, and any renewals thereof, from the FCC and any appropriate State PUC and any municipal authority, and make all filings and reports and pay all fees reasonably necessary or required for the continued operation of its business, as and when such Permits, filings or reports are necessary or required, other than any Permits, filings or reports which would not, individually or in the aggregate, have a Material Adverse Effect.

5.15 FCC/State PUC Applications.

(a) As promptly as practicable after the execution and delivery of this Agreement, ATX shall prepare and deliver to CoreComm ATX's completed portion of all appropriate applications for FCC State PUC and municipal authority approval, and such other documents as may be required, with respect to the assignment of ATX's Permits to CoreComm (collectively, the "FCC/State PUC Applications"). As promptly as practicable after the execution and delivery of this Agreement, CoreComm shall prepare and deliver to ATX, CoreComm's portion of all appropriate FCC/State PUC Applications. As soon as practical after the execution and delivery of this Agreement, the parties shall file, or cause to be filed, the FCC/State PUC Applications. If the Closing shall not have occurred for any reason within any applicable initial consummation period relating to the FCC's or the State PUCs grant of the FCC/State PUC Applications, and neither ATX nor CoreComm shall have terminated this Agreement pursuant to Section 8.1, CoreComm and ATX shall jointly request one or more extensions of the consummation period of such grant. No party hereto shall knowingly take, or fail to take, any action if the intent or reasonably anticipated consequence of such action or failure to act is, or would be, to cause the FCC or State PUCs not to

B-47

B-56

Agreement), each of the ATX Stockholders hereby agree, jointly and severally, to indemnify and hold harmless ATX from and after the Closing against and with respect to any and all claims, demands, losses, costs, expenses, obligations, liabilities, damages, recoveries, and deficiencies, including interest, penalties, and reasonable fees and expenses of attorneys, experts, personnel and consultants incurred by the Indemnified Party (as defined herein) (including in any action or proceeding between the Indemnifying Party (as defined herein) and the Indemnified Party or between the Indemnified Party and any third party or otherwise) (together referred to as "ATX Losses") resulting from (i) any breach of a representation, warranty, covenant, or agreement made by ATX, ATX Merger Sub, or any of the ATX Stockholders, in this Agreement, the ATX Disclosure Schedules or any other certificate or document delivered by ATX, ATX Merger Sub or any of the ATX Stockholders to CoreComm pursuant to this Agreement each of which representation, warranty, covenant or agreement shall be considered without regard to any materiality or Material Adverse Effect qualification therein for purposes of determining whether a breach has occurred, and any and all demands, claims, actions, suits or proceedings, assessments, judgments, costs and legal and other expenses incident to the foregoing, and (ii) the failure of ATX to have either applied for or obtained any necessary regulatory authorization or approval from any state public utilities commission or comparable entity (regardless of whether or not such failure is disclosed in the ATX Disclosure Schedule) in any state in which ATX had in excess of $25,000 of revenues from intra-state operations in calendar year 1999.

9.2 Procedures for Indemnification.

(a) Promptly after receipt by a party (the "Indemnified Party") of notice of the commencement of any action by a person not a party to this Agreement involving the subject matter of the foregoing indemnity provisions other than with respect to Taxes (a "Third Party Suit"), such Indemnified Party shall, if a claim thereof is to be made against another party hereto (the "Indemnifying Party") pursuant to the provisions of Section 9.1, promptly notify such Indemnifying Party of the commencement thereof; but the omission to so notify such Indemnifying Party will not relieve it from any liability which it may have to the Indemnified Party to the extent the Indemnifying Party was not prejudiced by such omission.

(b) The Indemnifying Party shall have ten (10) days from receipt of such notice to notify the Indemnified Party whether or not it disputes its liability to the Indemnified Party with respect to such Third Party Suit and whether or not it desires, at its sole cost and expense, to defend such Third Party Suit. If the Indemnifying Party shall so notify the Indemnified Party that it desires to defend against such Third Party Suit, the Indemnifying Party shall have the right to defend against such Third Party Suit (unless (i) the Indemnifying Party is also a party to such Proceeding and the Indemnified Party determines in good faith that joint representation would be inappropriate, or (ii) the Indemnifying Party fails to provide reasonable assurance to the Indemnified Party of its financial capacity to defend such Proceeding and provide indemnification with respect to such Proceeding), with counsel reasonably satisfactory to such Indemnified Party, by

B-57

appropriate proceedings which shall be promptly settled or prosecuted by the Indemnifying Party, so long as it diligently conducts such defenses, to a final conclusion such that a (i) it will be conclusively established for purposes of this Agreement that the claims made in that Proceeding are within the scope of and subject to indemnification; (ii) no compromise or settlement of such claims may be effected by the Indemnifying Party without the Indemnified Party's consent unless (A) there is no finding or admission of any violation of Laws or any violation of the rights of any Person and no effect on any other claims that may be made against the Indemnified Party, and (B) the sole relief provided is monetary damages that are paid in full by the Indemnifying Party; and (iii) the Indemnified Party will have no liability with respect to any compromise or settlement of such claims effected without its consent and the Indemnified Party shall receive a full release. The Indemnified Party may elect to participate in any such contest at its own cost and expense; provided, however, that the control of such contest shall rest primarily with the Indemnifying Party.

(c) Notwithstanding the foregoing (i) if the defendants in any action include both the Indemnified Party and the Indemnifying Party and the Indemnified Party shall have reasonably concluded that there may be legal defenses available to it which are different from or additional to those available to the Indemnifying Party, or if there is a conflict of interest which would prevent counsel for the Indemnifying Party from also representing the Indemnified Party, the Indemnified Party shall have the right to select separate counsel to participate in the defense of such Third Party Suit on behalf of such Indemnified Party, at the cost of the Indemnified Party; and (ii) in the event that such Third Party Suit involves potentially criminal or fraudulent activity of an Indemnifying Party, the Indemnified Party shall have the right, at its sole option, to defend such Third Party Suit at the expense of the Indemnifying Party.

(d) If the Indemnifying Party shall fail to elect to defend against such Third Party Suit, then the amount of any such Third Party Suit, including all losses, judgments, expenses and costs incurred by the Indemnified Party in connection with any defense thereof shall be deemed to be a liability of the Indemnifying Party hereunder.

(e) After notice from the Indemnifying Party to such Indemnified Party of its election to assume the defense thereof, the Indemnifying Party shall not be liable to the Indemnified Party pursuant to the provisions of Sections 9.1 for any legal or other expense subsequently incurred by such Indemnified Party in connection with the defense thereof other than reasonable costs of investigation, unless (i) the Indemnified Party shall have employed counsel in accordance with Subsection (c) above, (ii) the Indemnifying Party shall not have employed counsel reasonably satisfactory to the Indemnified Party to represent the Indemnified Party within a reasonable time after the notice of the commencement of the action, or (iii) the Indemnifying Party has authorized the employment of counsel for the Indemnified Party at the expense of the Indemnifying Party.

(f) In the event the Indemnified Party shall have any claim against the Indemnifying Party hereunder which does not involve a claim or demand by or against a third party, the Indemnified Party shall promptly notify the Indemnifying Party of such

B-58

claim, providing reasonable details of the facts giving rise to the claim and a statement of the Indemnified Party's Loss in connection with the claim, to the extent such Loss is then known to the Indemnified Party and, otherwise, an estimate of the amount of the Loss that it reasonably anticipates that it will incur or suffer; however, failure by the Indemnifying Party to give notice shall not prejudice any rights contained herein.

9.3 Cooperation in Defense. In case of any claim, arbitration or legal proceeding, the defense of which is assumed by an Indemnifying Party in accordance with this Article 9, the Indemnified Party, upon request of the Indemnifying Party, shall provide reasonable cooperation (at the expense of the Indemnifying Party in accordance with this Article 9) in the defense thereof.

9.4 Limitations on Indemnification by ATX Stockholders. Notwithstanding
Section 9.1 or any other provision of this Agreement or applicable law, the ATX Stockholders' aggregate liability for ATX Losses indemnified pursuant to Section 9.1 is subject to the following limitations:

(a) The ATX Stockholders shall have no liability for any ATX Loss unless notice of a claim for such ATX Loss, specifying in reasonable detail the basis for such claim, is made upon ATX Stockholders prior to the expiration of the survival periods set forth in Section 10.1. The ATX Stockholders' maximum aggregate liability for ATX Losses shall be $250,000,000; plus the aggregate amount of any costs, charges and expenses (including without limitation legal expenses) incurred by ATX and CoreComm in bringing or enforcing any claims against the ATX Stockholders under this Agreement.

(b) The ATX Stockholders shall be liable for ATX Losses (other than ATX Losses due to or arising out of any inaccuracy in or any breach of a representation, warranty, covenant or agreement of ATX, ATX Merger Sub or the ATX Stockholders contained in Sections 3.1, 3.2, 3.3 and 3.20) (the "Basket Exclusions"), only if and to the extent that the aggregate ATX Losses exceed $10,000,000; provided, however, that the ATX Stockholders shall be liable only for amounts in excess of $5,000,000 (including the Basket Exclusions); provided further that the ATX Stockholders shall be liable for all ATX Losses related to the Basket Exclusions.

9.5 Mitigation of Losses.

(a) ATX Losses shall be subject to appropriate mitigation for (i) any actual recovery from third parties (less attorneys' fees, expenses and other costs of recovery), (ii) the actual collection of insurance proceeds (less attorneys' fees, expenses and other costs of recovery, net of any adjustments to the corresponding insurance premiums).

(b) Where an Indemnified Party is entitled (whether by right of indemnity, reimbursement or any other means) to recover from any Person (not being any employee or officer of an Indemnified Party, but including its or their insurers) any sum with respect to any matter giving rise to a claim, then (subject first to being indemnified and secured to the reasonable satisfaction of an Indemnified Party against all costs, expenses, tax or other liabilities which may be thereby incurred) the Indemnified Party

B-59

shall take all reasonable steps to enforce such recovery (keeping the Indemnifying Party fully informed of the progress of any action taken) and account to the Indemnifying Party for any net amounts that are recovered (not exceeding the amount previously paid by the Indemnifying Party and after first taking account of any liability or loss of the Indemnified Party with respect to which the Indemnifying Party is not liable).

9.6 Exclusivity. Following the Closing, the remedies (subject to the limitations) set forth in this Article 9 shall be the sole remedy for claims for liability for ATX Losses arising under this Agreement.

9.7 Indemnification Escrow. Upon the Recapitalization, 27% of the shares of ATX Common Stock comprising the Exchange Consideration shall be deposited in escrow (the "Indemnification Escrow") pursuant to an escrow agreement among ATX, each ATX Stockholder and an escrow agent selected by such parties with the consent of CoreComm (the "Indemnification Escrow Agreement"). Such shares
(together with any distributions thereon or the proceeds from the sales thereof) shall be held in the Indemnification Escrow subject to the terms of the Indemnification Escrow Agreement to secure the indemnification obligations of the ATX Stockholders under Section 9.1 hereof, and such assets shall be held and disbursed in accordance with the terms of the Indemnification Escrow Agreement. In the event of any claim by ATX against such assets, the shares of ATX Common Stock shall be valued at the closing price on the business day immediately preceding the date on which such shares are to be disbursed to an Indemnified Party in accordance with the terms of the Indemnification Escrow Agreement.

X. SURVIVAL OF REPRESENTATIONS AND WARRANTIES

WHEREAS, each Stockholder has independently determined that the Merger is in its best interest and each Stockholder wishes to facilitate the consummation of the Merger by entering into this Agreement and agreeing to be bound by the terms hereof;

NOW, THEREFORE, in consideration of the premises and of the mutual agreements, provisions and covenants herein contained, each Stockholder and the Company hereby agree as follows:

Section 1 Covenants of Stockholders with Respect to Voting Securities of the Company.

B-71

During the term of this Agreement and subject to all of the provisions hereof, each Stockholder and the Company agree as follows:

1.1 Acquisition of Voting Securities. Each Stockholder shall not acquire, agree to acquire or offer or propose to acquire, directly or indirectly, or in conjunction with or through any Person, record or beneficial ownership of any Voting Securities (as hereinafter defined), except (i) through the exercise of conversion rights, if any, of Voting Securities (including any conversion of the Preferred Stock); (ii) by way of stock splits, reclassifications or stock dividends or other distributions or offerings made on a pro rata basis to holders of Voting Securities or any class of Voting Securities; (iii) from another Stockholder by bequest (including, without limitation, through the creation of a trust), gift, will, pledge, hypothecation or otherwise in accordance with clause (i) of Section 1.6 hereof; (iv) pursuant to a bequest or similar gift or transfer from a Person who is not a Stockholder, including, without limitation, through the creation of a trust for the benefit of a Stockholder; (v) pursuant to a will or the laws of descent and distribution from a Person who is not a Stockholder; or (vi) pursuant to the grant or exercise of stock options or the receipt of other compensation or benefits involving Voting Securities granted to a Stockholder in such Stockholder's capacity (if applicable) as an employee or consultant of the Company or any subsidiary of the Company; provided, however, that if, in connection with the transfer of Voting Securities to a Stockholder pursuant to clauses (iv) and (v) of this Section 1.1, a trust, corporation or other entity is formed for the purpose of holding Voting Securities for the benefit of a Stockholder (other than solely as an income beneficiary of a trust), then, as a condition precedent to the receipt by such Stockholder of any direct or indirect beneficial interest in such Voting Securities, such trust, corporation or other entity shall agree to be bound by the terms and conditions of a stockholder agreement having the same or substantially the same terms and conditions as this Agreement.

If a Stockholder shall acquire, directly or indirectly, record or beneficial ownership of, or the right to acquire, any Voting Securities in contravention of this Agreement, then such Stockholder shall promptly notify the Company, and the Company, in its sole discretion, may either (x) purchase (or cause its designee(s) to purchase) any or all of such acquired Voting Securities at a price equal to the price paid by such Stockholder or (y) require such Stockholder to dispose of, within 30 days from the date on which the Company requests such Stockholder to do so, only in accordance with the provisions of

Each Stockholder hereby acknowledges that any acquisition of Voting Securities in contravention of this Agreement shall constitute a breach of this Agreement and that the Company's right to purchase or require the disposition of Voting Securities pursuant to this Section 1.1 shall not be exclusive and shall be in addition to any other rights and remedies the Company may have in connection with a breach of this Agreement.

(d) otherwise hereinafter acquired, with respect to which such Stockholder has the legal capacity to vote or to direct the vote of such Voting Securities, on each matter submitted to a vote of the stockholders of the Company, (x) in the same proportion as the votes cast by all holders of Voting Securities other than the Stockholders and any affiliates and associates of the Company, with respect to such matter, or, (y) in the event of a proposed change of control transaction for the Company, in the manner recommended to the stockholders by the Board of Directors of the Company provided that the Board of Directors, prior to such recommendation, shall have received an opinion from a nationally recognized investment banking firm to the effect that the transaction or the consideration to be received by the unaffiliated holders of the Common Stock is fair from a financial point of view to such stockholders; provided, further, that in the absence of such opinion such Voting Securities shall be voted as provided in clause (x) of this Section 1.2.

(a) Prior to ,(1) no Stockholder shall directly or indirectly, offer, sell, assign, pledge, encumber or otherwise dispose of or transfer in any manner any shares of Common Stock held by such Stockholder (the shares of Common Stock which may not be offered, sold, assigned, pledged, encumbered or otherwise disposed of during such period being the "Restricted Shares"), except that the Restricted Shares may be pledged in respect of a margin loan or to a bona fide third party lending institution provided that the pledgee shall be bound by the restrictions contained in this sentence; provided however, that if less than 50% of the Senior Notes (as defined in the Merger Agreement) issued to the Stockholders pursuant to the Merger Agreement have been repaid within six (6) months of the Closing (as defined in the Merger Agreement), the restrictions set forth in this Section 1.6(a), with respect to 25% of the Restricted Shares held by such Stockholder shall terminate on the six month anniversary of the Closing; provided, however, that disposition of any such shares that are released from such restrictions shall be subject to the volume limitations set forth in Rule 144(e) under the Securities Act.

(b) In addition, except as set forth above no Stockholder shall, directly or indirectly, offer, sell, assign, pledge, encumber or otherwise dispose of or transfer in any manner any Voting Securities (or enter into agreements or understandings with respect to the foregoing), if after such disposition, the Person holding such Voting Securities would own 5% or more of the Total Voting Power (or Voting Securities which are convertible into or exercisable for shares which, after giving effect to such exercise or conversion, would represent 5% or more of the Total Voting Power). Any offer, sale, assignment, pledge, encumbrance or other disposition or transfer of Voting Securities not otherwise prohibited by this Agreement shall only be effected, to the extent otherwise legally permissible, in the following manners: (i) pursuant to a bona fide public offering of Voting Securities (which may include a secondary distribution effected through the facilities of any national securities exchange on which the Voting Securities are listed); provided, however, that in case of any such proposed public offering, each Stockholder selling pursuant to such offering (the "Selling Stockholder") will use his/her/its best efforts (and will instruct the managing underwriter of any such public offering or broker-dealer to or through which such public offering is being made to use its best efforts) to achieve a sufficiently broad public distribution of the securities being offered (in light of the number of securities being offered), with the intention that no person or related group of persons should purchase in such public offering Voting Securities representing 5% or more of the Total Voting Power; (ii) pursuant to an unsolicited open market sale


(1) Nine (9) months from the closing.

B-74

(iii) pursuant to a tender offer made by the Company or any subsidiary of the Company or made by a third person to the stockholders of the Company as to which the Company's Board of Directors has recommended to the stockholders of the Company; (iv) pursuant to a privately-negotiated transaction with a Person who is not a Stockholder; provided, that in no case shall any such sale, transfer or other disposition under this clause (iv) be made to such Person if, immediately after such transaction, such Person (based upon the written representation of such Person, which as a condition precedent to such sale, transfer or other disposition shall be delivered to such Stockholder and to the Company prior to the consummation of such transaction), together with its affiliates and associates would be the direct or indirect beneficial or record owner of Voting Securities (when added to the Voting Securities (if any) already beneficially owned by such Person and its affiliates and associates) representing in excess of 5% of the Total Voting Power; (v) pursuant to a will or the laws of descent and distribution; provided, that the estate of a Stockholder shall be bound by the terms and conditions of this Agreement and if, immediately after any distribution out of such estate, any distributee, together with such distributee's affiliates and associates would (other than solely as an income beneficiary of a trust) be the direct or indirect beneficial or record owner of, or have the right to acquire, Voting Securities (when added to the Voting Securities (if any) already owned by such distributee and his/her affiliates and associates representing in excess of 5% of the Total Voting Power, then such distributee shall, as a condition precedent to receiving such shares of Voting Securities, agree to be bound by the terms and conditions of a stockholder agreement having the same terms and conditions as this Agreement; (vi) pursuant to a bequest or similar gift or transfer to any Person who is not a Stockholder or; provided that if, immediately after delivery of a bequest or similar gift or transfer, including, but not limited to, through the creation of a trust, the recipient, together with such recipient's affiliates and associates (including, as the case may be, the Stockholder making such transfer), would (other than solely as an income beneficiary of a trust) be the direct or indirect beneficial or record owner of, or have the right to acquire, Voting Securities (when added to the Voting Securities (if any) already owned by such recipient and its affiliates and associates (including, as the case may be, the Stockholder making such transfer)) representing in excess of 5% of the Total Voting Power, then such recipient shall, as a condition precedent to receiving such shares of Voting Securities, agree to be bound by the terms and conditions of a stockholder agreement having the same terms and conditions as this Agreement; or
(vii) as a result of any pledge or hypothecation to a bona fide financial institution to secure a bona fide loan, guaranty or other financial accommodation or as a result of any foreclosure with respect thereto; provided, however, that in connection with any transfer by a Stockholder of Voting Securities pursuant to clauses (v) or (vi) of this Section 1.6 to a trust, corporation or other entity and a

B-75

Stockholder retains the authority, as trustee or otherwise, to vote, acquire or dispose of, or to direct the voting, acquisition or disposition of, Voting Securities to be held by such trust or other entity, then as a condition precedent to the transfer of such shares of Voting Securities to such trust or other entity, such Stockholder shall cause such trust or other entity to be bound by the terms and conditions of a stockholder agreement having the same or substantially the same terms and conditions as this Agreement.

Notwithstanding anything to the contrary contained herein, a Stockholder shall not dispose of or otherwise transfer any Voting Securities in violation of the provisions of Section 5 of the Securities Act.

1.7 No Solicitation. No Stockholder shall propose, solicit or participate in any fashion, in any transaction relating to an acquisition of, a business combination or similar transaction with, or a change of control of, the Company or make or solicit or encourage any Person to make a tender offer for Voting Securities.

1.8 Legend on Voting Securities. Each Stockholder agrees that each certificate representing its Voting Securities shall bear the following legend, which will remain thereon as long as such Voting Securities are subject to the restrictions contained in this Agreement:

The shares represented by this certificate are subject to the provisions of a Stockholder Agreement dated as of , 2000, among the Company and certain Stockholders, and may not be sold or transferred except in accordance therewith. Copies of said Agreement are on file at the offices of the Secretary of the Company.

The Company may enter a stop transfer order with the transfer agent (or agents) and the registrar (or registrars) of the Voting Securities against the transfer of legended Voting Securities held by a Stockholder except in compliance with the requirements of this Agreement. The Company agrees to remove promptly any stop transfer order with respect to, and issue promptly either legended (if the Voting Securities remain subject to the restrictions of this Agreement) or unlegended certificates in substitution for, certificates for any such Voting Securities that are no longer subject to or are to be transferred in compliance with the restrictions contained in this Agreement. Without limiting the generality of the foregoing, the Company shall promptly remove any stop transfer order in effect with respect to such certificates, upon the delivery to the Company of an opinion of counsel to a Stockholder, in form and substance reasonably satisfactory to the Company, that legended certificates representing Voting Securities are no longer subject to this Agreement or that such Voting Securities are being transferred in compliance with the provisions of Sections 1.6, and shall promptly issue unlegended certificates in substitution for such legended certificates, except if such legended certificates are being transferred pursuant to Section 1.6 to a transferee who shall be bound by the terms and conditions of a Stockholder Agreement, in which event the Company may issue legended certificates.

The term of this Agreement shall commence at the Effective Time and shall terminate with respect to any given Stockholder (but only such Stockholder) (x) in the case of Michael Karp and The Florence Karp Trust, when such Stockholders (together with any transferees who are members of such Stockholder's immediate family or entities described in clause (v) of Section 1.6 hereof) ceased to own Voting Securities having, in the aggregate, 5% or more of the Total Voting Power, and (y) in the case of each of Debra Buruchian and Thomas Gravina, when such Stockholder (together with any transferees who are members of such Stockholder's immediate family or entities described in clause (v) of Section 1.6 hereof) ceases to own less than 50% of the Voting Securities issued to such party pursuant to the Recapitalization (after giving effect to any stock splits or stock dividends), unless the transaction or transactions which resulted in such Stockholder ceasing to hold such threshold number or percentage of Voting Securities shall have violated the terms of this Agreement. For purposes hereof, ownership of Voting Securities shall include record ownership of such securities as well as beneficial ownership thereof within the meaning of Rule 13d-3 under the Securities Exchange Act of 1934, as amended.

REGISTRATION RIGHTS AGREEMENT, dated as of , 2000 (the "Agreement"), by and between ATX Telecommunications Services, Inc. , a Delaware corporation (the "Company"), and each of Michael Karp ("Karp"), Debra Buruchian ("Buruchian"), Thomas Gravina ("Gravina") and The Florence Karp Trust (the "Trust"). Each of Karp, Buruchian, Gravina and the Trust is referred to as a "Stockholder").

WHEREAS, pursuant to a Recapitalization Agreement and Plan of Merger, dated as of March 9, 2000, as amended (the "Recapitalization and Merger Agreement"), by and among the Company, CoreComm Limited ("CoreComm"), and, with respect to certain provisions thereof, the Stockholders, ATX Merger Sub, Inc. ("ATX Merger Sub") and CoreComm Merger Sub, Inc. ("CoreComm Merger Sub") (i) CoreComm has been merged with and into CoreComm Merger Sub (with each issued and outstanding share of CoreComm's common stock converted into a share of common stock of CoreComm Merger Sub) (the "Domestication Merger"); (ii) CoreComm Merger Sub is being merged with and into the Company (the "Merger"); and (iii) the Company is being recapitalized by exchanging each pre-recapitalization share of the Company's common stock for shares of the Company's post-recapitalization common stock, par value $.01 per share (the "Common Stock"), shares of the Company Convertible Preferred Stock, par value $.01 per share (the "Preferred Stock"), and $150 million in cash and Senior Notes (as defined in the Recapitalization and Merger Agreement) with a possible issuance of up to $110 million in notes (the "Recapitalization").

WHEREAS, the Stockholders are the holders of all of the outstanding pre- recapitalization shares of the Company's common stock and it is a condition to the consummation of the recapitalization and the other transactions contemplated by the Recapitalization and Merger Agreement that the Company grant to the Stockholders the registration rights and other rights set forth herein; and

In consideration of the mutual covenants and agreements set forth herein and for good and valuable consideration, the receipt of which is hereby acknowledged, the parties hereto agree as follows:

1. General; Securities Subject to this Agreement.

1.1 Grant of Rights. The Company hereby grants registration rights to the Stockholders upon the terms and subject to the conditions set forth in this Agreement. Capitalized terms used herein and not defined shall have the meanings assigned to such terms in the Recapitalization and Merger Agreement.

1.2 Registrable Securities. For the purposes of this Agreement, "Registrable Securities" means, each of the following: (a) any shares of Common Stock issued to the Stockholders pursuant to the Recapitalization and Merger Agreement, (b) any shares of Preferred Stock issued to the Stockholders pursuant to the Recapitalization and Merger

B-83

Agreement, (c) any shares of Common Stock issued upon conversion of, or as payment of dividends on, or in exchange for shares of the Preferred Stock issued pursuant to the Recapitalization and Merger Agreement, and (d) any shares of Common Stock issued in payment of a dividend on the Senior Notes (as defined in the Recapitalization and Merger Agreement); provided, however, that shares shall cease to be Registrable Securities for purposes of this Agreement when a registration statement covering such Registrable Securities has been declared effective under the Securities Act by the SEC and all such Registrable Securities have been disposed of pursuant to such effective registration statement.

1.3 Stockholders of Registrable Securities. A Person is deemed to be a holder of Registrable Securities whenever such Person (i) is a party to this Agreement (or a permitted transferee thereof) and (ii) owns of record Registrable Securities. If the Company receives conflicting instructions, notices or elections from two or more Persons with respect to the same Registrable Securities, the Company may act upon the basis of the instructions, notice or election received from the registered owner of such Registrable Securities.

2. Demand Registration Rights.

2.1 Shelf and Demand Registration.

(a) Within 15 days following the Closing (as defined in the Merger Agreement), the Company shall cause to be filed with the Securities and Exchange Commission a Registration Statement registering under Rule 415 under the Securities Act all Registrable Securities (the "Shelf Registration"). The Company shall use its reasonable best efforts to cause such Shelf Registration to be declared effective under the Securities Act as soon as practicable following the filing thereof, and shall use its reasonable best efforts to cause such Shelf Registration to remain continuously effective under the Securities Act until such time as the securities which have been issued to the Stockholders at the Closing (as defined in the Recapitalization and Merger Agreement) may be freely sold without regard to the volume limitations under Rule 144 of the Securities Act by a Stockholder who is not otherwise an Affiliate of the Company within the meaning of Rule 144 (or such shorter period that will terminate when all Registrable Securities covered by the Shelf Registration have been sold). Subject to the provisions of Section 2.1(d), the Company agrees, if necessary, to supplement or make amendments to the Shelf Registration, if required by the registration form used by the Company for the Shelf Registration or by the instructions applicable to such registration form or by the Securities Act or the rules or regulations thereunder.

(b) At any time on or after the Closing, the Stockholders may make a written request (specifying the intended method of disposition) (such Stockholders, the "Initiating Common Stockholders") for one additional registration under the Securities Act (a "Demand Common Registration") of all or part of the shares of Common Stock which constitute such Initiating Stockholders' Registrable Securities; provided, however, that, (i) the number of shares of Common Stock proposed to be registered by the Initiating Common Stockholders in any Demand Common

B-84

Registration shall not be less than 1,500,000 shares (subject to appropriate adjustments to reflect stock splits, stock dividends, corporate recapitalizations or similar transactions) as of the date of the request, and (ii) the Initiating Common Stockholders shall be the holders as of the date of the request of at least 25% of the then outstanding shares of Common Stock that constitute Registrable Securities hereunder; provided, however, that such Demand Common Registration may be requested by Initiating Common Stockholders owning less than 25% of the then outstanding shares of Common Stock that constitute Registrable Securities hereunder so long as such Initiating Common Stockholders are the holders as of the date of the request of at least 10% of the then outstanding shares of Common Stock that constitute Registrable Securities hereunder.

(c) At any time on or after the Closing, the Stockholders may make a written request (specifying the intended method of disposition) (such Stockholders, the "Initiating Preferred Stockholders") for one additional registration under the Securities Act (a "Demand Preferred Registration") of all or part of the shares of Preferred Stock which constitute such Initiating Stockholders' Registrable Securities; provided, however, that,
(i) the face value of the shares of Preferred Stock proposed to be registered by the Initiating Stockholders shall not be less than $80,000,000 as of the date of the request, and (iv) the Initiating Preferred Stockholders shall be the holders as of the date of the request of at least 25% of the then outstanding shares of Preferred Stock that constitute Registrable Securities hereunder.

(d) If, so long as the Shelf Registration is in effect or at the time a demand for a Demand Registration (as defined below) is received by the Company, the Company is engaged in, or within 90 days plans to engage in a registered public offering for its own account or any other activity which, in the good faith determination of the Board of Directors of the Company, would (i) be required to be disclosed in a Demand Registration or which, under applicable law would require an amendment of or supplement to the Shelf Registration, and (ii) be materially and adversely affected by the proceeding with any such Demand Registration or amending or supplementing the Shelf Registration (each, a "Company Event"), then the Company may at its option direct that sales under the Shelf Registration be suspended, and requests for a Demand Registration be delayed for a reasonable period of time not in excess of three (3) months from the effective date of such offering or the date of completion of such other activity, as the case may be, such right to delay a Demand Registration or to suspend sales under the Shelf Registration to be exercised by the Company not more than once in any 365-day period; provided, however, that if the Company receives a written request from Initiating Common Stockholders or the Initiating Preferred Stockholders (the "Initiating Stockholders") to register the Registrable Securities of such Stockholders prior to the occurrence of a Company Event, then such registration shall not be delayed by any registration statement thereafter effected by the Company. In addition, the Company shall not be required to effect any Demand Registration within three (3) months after the effective date of any other registration statement

B-85

of the Company (other than the Shelf Registration). Within ten days after receipt of a request for a Demand Common Registration or a Demand Preferred Registration (each, a "Demand Registration"), the Company shall give written notice (the "Notice") of such request to all other Stockholders holding the class of stock to which such Demand Registration relates and shall include in such registration all Registrable Securities of that class that the Company has received written requests for inclusion therein within 15 days after the Notice is given. Thereafter, in the case of Demand Common Registration, the Company may elect to include in such registration additional shares of Common Stock issued by the Company. All requests made pursuant to this Section 2.1 (other than the Shelf Registration), shall specify the class and aggregate number of Registrable Securities to be registered.

2.2 Effective Demand Registration. The Company shall use reasonable commercial efforts to cause any Demand Registration to become effective not later than ninety (90) days after it receives a request under Section 2.1 of this Agreement and to remain effective for the lesser of (i) the period during which all Registrable Securities registered in the Demand Registration are sold and (ii) one hundred and twenty (120) days; provided, however, that if the Initiating Stockholders request the Company to withdraw such registration, other than as the result of a breach by the Company, it shall constitute a Demand Registration unless the Initiating Stockholders promptly pay all of the costs and expenses incurred by the Company in connection with such registration.

2.3 Underwriting Procedures.

(a) The offering of Registrable Securities pursuant to a Demand Registration shall be in the form of a firm commitment underwritten offering and the managing underwriter and other underwriters selected for such offering shall be selected by the Initiating Stockholders, provided that the managing underwriter and other underwriters are reasonably acceptable to the Company (having due regard to the experience and relationship with the Company of the managing underwriter and the other underwriters) (the "Approved Demand Underwriter"). In such event, if the Approved Demand Underwriter advises the Company in writing that in its opinion the aggregate amount of such Registrable Securities requested to be included in such offering is sufficiently large to have a material adverse effect on the success of such offering, the Company shall include in such registration only the aggregate amount of Registrable Securities that in the opinion of the Approved Demand Underwriter may be sold without any such material adverse effect and shall reduce pro rata based on the number of Registrable Securities included in the request for Demand Registration, the amount of Registrable Securities to be included by each Stockholder in such registration.

(b) An offering of Registrable Securities under the Shelf Registration may, but need not be, pursuant to an underwritten offering. However, if any such offering is to be pursuant to an underwritten offering, the Stockholder or Stockholders intending to sell Registrable Securities in such underwritten offering shall give the

B-86

Company written notice of their desire to proceed with an underwritten offering under the Shelf Registration. Only one underwritten offering under the Shelf Registration shall be permitted, and any such offering must be for at least 1,500,000 shares of Common Stock (subject to appropriate adjustments to reflect stock splits, stock dividends, corporate recapitalizations or similar transactions) or at least $80,000,000 face amount of Preferred Stock. The managing underwriter and other underwriters selected for such offering shall be selected by the Stockholders seeking to sell such shares through such underwriter, provided that the managing underwriter and other underwriters are reasonably acceptable to the Company (having due regard to the experience and relationship with the Company of the managing underwriter and the other underwriters) (the "Approved Shelf Underwriter" and together with an Approved Demand Underwriter, an "Approved Underwriter").

(c) Distribution by Underwriters. The managing underwriter or underwriters selected for any offering shall enter into an agreement with the Company and the Stockholders whereby the underwriters shall be prohibited from (i) distributing 5% or greater of the Registrable Securities to any Person in connection with the initial placement of the Registrable Securities for the offering and from (ii) distributing 5% or greater of the Registrable Securities to any Person for 90 days after such initial placement.

3. Incidental or "Piggy-Back" Registration Rights.

3.1 Notice of Registration. If, at any time or from time to time prior to the fourth anniversary of the date hereof, the Company shall determine to register any of its Common Stock for sale in an Underwritten Offering for its own account (other than a registration relating to (i) a registration of an employee compensation plan or arrangement adopted in the ordinary course of business on Form S-8 (or any successor form) or any dividend reinvestment plan or (ii) a registration of securities on Form S-4 (or any successor form) including, without limitation, in connection with a proposed issuance in exchange for securities or assets of, or in connection with a merger or consolidation with another corporation) (a "Company Registration"), or shall register any of its Common Stock pursuant to a demand request for registration by any holder of the Company's Common Stock other than the Stockholders (a "Third Party Demand Registration"), the Company will promptly give to the Stockholders written notice thereof, and include in such registration (subject to Section 3.2) all the Common Stock Registrable Securities specified in a written request made by any one or more of the Stockholders within ten days after such Stockholder's receipt of such written notice from the Company ("Incidental Registration"). The right of the Stockholder to have Common Stock Registrable Securities included in a registration pursuant to this Section 3.1 shall be conditioned upon such Stockholder entering into (together with the Company and/or the other holders, if any, distributing their securities through such underwriting) an underwriting agreement in customary form with the managing underwriter or underwriters selected for such underwriting by the Company or by

B-87

the stockholders who have demanded such registration (the "Company Underwriter").

3.2 Cutback. If the lead managing underwriter of an offering covered by Section 3.1 shall advise the Company in writing on or before the date five days prior to the date then scheduled for such offering that, in its opinion, the amount of Common Stock (including Common Stock Registrable Securities) requested to be included in such registration exceeds the amount which can be sold in such offering without adversely affecting the distribution of the Common Stock being offered, then the Company will include in such registration:

(i) in the case of a Company Registration, first, any shares proposed to be offered by the Company; second, Registrable Securities requested to be registered by the Stockholders and any other shares requested by other stockholders of the Company, including the Stockholders, to be included in such registration, allocated, if necessary, pro rata among the Stockholders and such other holders requesting such registration on the basis of the number of the shares Beneficially Owned at the time; and

(ii) in the case of a Third Party Demand Registration, first, any shares proposed to be offered by the stockholder or stockholders exercising their right to cause the Company to proceed with such Third Party Demand Registration (the "Initiating Third Party Holders"), second, any shares proposed to be offered by the Company, and third, Registrable Securities requested to be registered by the Stockholders and any other shares requested by other stockholders of the Company, including the Stockholders but excluding the Initiating Third Party Holders, to be included in such registration, allocated, if necessary, pro rata among the Stockholders and such other holders requesting such registration on the basis of the number of the shares Beneficially Owned at the time;

provided, however, that in the event the Company will not, by virtue of the foregoing cut-back mechanism, include in any such registration all of the Common Stock Registrable Securities requested to be included in such registration, the Stockholders may, upon written notice to the Company given within three days of the time the Stockholders first are notified of such matter, reduce the amount of Registrable Securities they desire to have included in such registration, whereupon only the Registrable Securities, if any, they desire to have included will be considered for such inclusion.

3.3 Right of Termination. The Company shall have the right to terminate or withdraw any registration initiated by it under Section 3.2 prior to the effectiveness of such registration whether or not the Stockholders have elected to include Registrable Securities in such registration.

4. Provisions Applicable to Demand and Piggy-Back Registrations.

4.1 Expenses. The Company shall pay all Registration Expenses (as defined in Section 6 hereof) incurred in connection with any registration pursuant to

B-88

Section 2 or 3 hereto, unless registration fails to become effective as a result of the fault of one or more Stockholders, in which case the Company will not be required to pay the Registration Expenses incurred with respect to the offering of such Stockholder's or Stockholders' Registrable Securities. The Registration Expenses incurred with respect to the offering of such Stockholder's or Stockholders' Registrable Securities shall be the product of (a) the aggregate amount of all Registration Expenses incurred in connection with such registration and (b) the ratio that the number of such Registrable Securities bears to the total number of Registrable Securities included in the registration.

4.2 Holdback Agreements. Each Stockholder agrees not to effect any public sale or distribution of any Registrable Securities being registered or of any securities convertible into or exchangeable or exercisable for such Registrable Securities, including a sale pursuant to Rule 144 under the Act, during the ninety (90) day period beginning on the effective date of any Demand Registration or Incidental Registration or other underwritten offering in which such Stockholder is participating (except as part of such registration), if and to the extent requested by any other Stockholders, in the case of a non-underwritten public offering, or if and to the extent requested by the Company Underwriter, in the case of an under-written public offering.

5. Registration Procedures.

In connection with any registration statement filed pursuant to this Agreement, the Company will, as expeditiously as possible:

(a) in connection with a request pursuant to this Agreement, prepare and file with the Commission, after receipt of a request to file a registration statement with respect to Registrable Securities, a registration statement on any form for which the Company then qualifies or which counsel for the Company shall deem appropriate and which form shall be available for the sale of such Registrable Securities in accordance with the intended method of distribution thereof and, if the offering is an underwritten offering, shall be reasonably satisfactory to the Approved Underwriters, and use its best efforts to cause such registration statement to become effective; provided, however, that before filing a registration statement or prospectus or any amendments or supplements thereto, the Company shall (i) furnish to the counsel selected by the Stockholder or Stockholders making the demand, if any, copies of all such documents proposed to be filed, and (ii) notify such counsel and each seller or prospective seller of Registrable Securities of any stop order issued or threatened by the Commission and take all reasonable actions required to prevent the entry of such stop order or to remove it if entered;

(b) in connection with a registration pursuant to this Agreement (other than a Shelf Registration), prepare and file with the Commission such amendments and supplements to such registration statement and the prospectus used in connection therewith as may be necessary to keep such registration statement effective for a period of not more than one hundred and twenty (120) days (or such shorter period

B-89

that will terminate when all Registrable Securities covered by such registration statement have been disposed of);

(c) furnish to each seller of Registrable Securities such number of copies of the registration statement, each amendment and supplement thereto (in each case including all exhibits thereto), the prospectus included in such registration statement (including each preliminary prospectus) and such other documents as each seller may reasonably request in order to facilitate the disposition of the Registrable Securities owned by such seller;

(d) use reasonable efforts to register or qualify such Registrable Securities under such other securities or "blue sky" laws of such jurisdictions as any seller or underwriter reasonably requests in writing and to do any and all other acts and things that may be reasonably necessary or advisable to register or qualify for sale in such jurisdictions the Registrable Securities owned by such seller; provided, however, that the Company shall not be required to (i) qualify generally to do business in any jurisdiction where it is not then so qualified, (ii) subject itself to taxation in any such jurisdiction, (iii) consent to general service of process in any such jurisdiction or (iv) provide any undertaking required by such other securities or "blue sky" laws or make any change in its charter or by-laws that the Board of Directors of the Company determines in good faith to be contrary to the best interest of the Company and its Stockholders;

(e) use reasonable efforts to cause the Registrable Securities covered by such registration statement to be registered with or approved by such other governmental agencies or authorities as may be necessary by virtue of the business and operations of the Company to enable the seller or sellers thereof or the Approved Underwriters, if any, to consummate the disposition of such Registrable Securities;

(f) notify each seller of such Registrable Securities at any time when a prospectus relating thereto is required to be delivered under the Securities Act of the happening of any event as a result of which the prospectus included in such registration statement contains an untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, and prepare and file with the Commission as soon thereafter as practicable, after consultation with the Initiating Stockholders and subject to the provisions of Section 2.1(d), a supplement or amendment to such prospectus so that, as thereafter delivered to the purchasers of such Registrable Securities, such prospectus will not contain an untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading;

(g) enter into customary agreements (including, in the case of a Demand Registration or a single underwritten offering under the Shelf Registration by Approved Shelf Underwriters an underwriting agreement in customary form) and take such other actions as are reasonably required in order to expedite or facilitate the disposition of such Registrable Securities in the manner permitted hereby;

B-90

(h) in the case of either a Demand Registration or a single underwritten offering under the Shelf Registration by Approved Shelf Underwriter, causing its officers to be available at reasonable times to participate in "road shows" and other information meetings organized by the managing Approved Demand Underwriter;

(i) otherwise use reasonable efforts to comply with all applicable rules and regulations of the Commission; and

(j) use reasonable efforts to cause all Registrable Securities covered by the registration statement to be listed on each securities exchange or market, if any, on which similar securities issued by the Company are then listed, provided that the applicable listing requirements are satisfied.

The Company may require each seller or prospective seller of Registrable Securities as to which any registration is being effected to furnish to the Company such information regarding the distribution of such securities and other matters as may be required to be included in the registration statement.

Each holder of Registrable Securities agrees that, upon receipt of any notice from the Company of the happening of any event of the kind described in paragraph (f) of this Section 5, such holder shall forthwith discontinue disposition of Registrable Securities pursuant to the registration statement covering such Registrable Securities until such holder's receipt of the copies of the supplemented or amended prospectus contemplated by paragraph (f) of this
Section 5 and, if so directed by the Company, such holder shall deliver to the Company all copies, other than permanent file copies then in such holder's possession or copies delivered to prospective purchasers, of the prospectus covering such Registrable Securities current at the time of receipt of such notice. If the Company shall give any such notice, the Company shall extend the period during which such registration statement shall be maintained effective pursuant to this Agreement (including the period referred to in paragraph (b) of this Section 5) by the number of days during the period from and including the date of the giving of such notice pursuant to paragraph (f) of this Section 5 to and including the date when each seller of Registrable Securities covered by such registration statement shall have received the copies of the supplemented or amended prospectus contemplated by paragraph (f) of this Section 5.

6. Registration Expenses. The Company shall pay all expenses incident to its performance of or compliance with this Agreement; provided, however, that the Company shall not pay the costs and expenses of any Stockholder relating to underwriters' commissions and discounts relating to Registrable Securities to be sold by such Stockholder, brokerage fees, transfer taxes or the fees or expenses of any counsel, accountants or other representatives retained by the Stockholders, individually or in the aggregate. All of the expenses described in this Section 6 that are to be paid by the Company are herein called the "Registration Expenses."

7. Indemnification; Contribution.

7.1 Indemnification by the Company. The Company agrees to indemnify, in the case of any registration statement filed pursuant to this Agreement, each seller

of any Registrable Securities covered by such registration statement, each other person who participates as an underwriter in the offering or sale of such securities, and each person, if any, who controls such seller or any such underwriter within the meaning of the Securities Act (collectively, the "Indemnified Parties") against any losses, claims, damages or liabilities to which such Indemnified Party may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any registration statement under which such securities were registered under the Securities Act, any preliminary prospectus, final prospectus or summary prospectus contained therein, or any amendment or supplement thereto, or any omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein in light of the circumstances in which they were made not misleading, or any violation by the Company of the Securities Act or any rule or regulation thereunder applicable to the Company; provided, however, that the Company shall not be liable to the extent that any loss, claim, or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in such registration statement, any such preliminary prospectus, final prospectus, summary prospectus, amendment or supplement in reliance upon and in conformity with written information furnished to the Company by or on behalf of such Indemnified Party expressly for use in the Registration Statement; provided, further, that the Company shall not be liable to any seller of Registrable Securities (or to any person who acts as an underwriter in such sale or who controls such seller) to the extent that any loss, claim, or liability arises out of an untrue statement, alleged untrue statement, omission, or alleged omission made in any preliminary prospectus if either (a)(i) such seller failed to send or deliver a copy of the prospectus with or prior to written confirmation of the sale by such seller to the person asserting the claim and (ii) the prospectus would have corrected such untrue statement, alleged untrue statement, omission or alleged omission; or (b)(x) such untrue statement, alleged untrue statement, omission or alleged omission is corrected in an amendment or supplement to the prospectus and (y) having been furnished by or on behalf of the Company with copies of the prospectus as so amended or supplemented, such seller fails to deliver such prospectus as so amended or supplemented, with or prior to the written confirmation of the sale by such seller to the person asserting the claim.

7.2 Indemnification by Stockholders. In connection with any registration statement in which a Stockholder is participating, each such Stockholder shall furnish to the Company in writing such information and affidavits with respect to such Stockholder as the Company reasonably requests for use in connection with any such registration statement or prospectus and agrees to indemnify, to the fullest extent permitted by law, the Company, its officers, directors and agents and each person, if any, who controls the Company (within the meaning of the Securities Act) against any and all losses, claims, damages, and liabilities resulting from any untrue or alleged untrue statement of a material fact or any omission or alleged

B-92

omission of a material fact required to be stated in any registration statement, prospectus or preliminary prospectus or any amendment thereof or supplement thereto or necessary to make the statements therein (in the case of a prospectus, in light of the circumstances under which they were made) not misleading, to the extent that such untrue or alleged untrue statement or omission is contained in or omitted from, as the case may be, any information or affidavit with respect to such Stockholder so furnished in writing by such Stockholder expressly for use in any such prospectus or preliminary prospectus; provided, however, that the liability of such Stockholder shall not exceed the net proceeds received by such Stockholder from the sale of its Registrable Securities. Each Stockholder also shall indemnify any underwriters of the Registrable Securities, their officers and directors and each person who controls such underwriters (within the meaning of the Securities Act) to the same extent as provided above with respect to the indemnification of the Company; provided, however, that the indemnification of such Stockholder shall be limited to the net proceeds received by such Stockholder from the sale of its Registrable Securities.

7.3 Contribution. If the indemnification provided for in this Section 7 is unavailable to any indemnified party hereunder in respect of any losses, claims, damages, liabilities or expenses referred to herein, then the indemnifying party, to the extent such indemnification is unavailable, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages, liabilities or expenses in such proportion as is appropriate to reflect the relative fault of the indemnifying party and indemnified parties in connection with the actions that resulted in such losses, claims, damages, liabilities or expenses. The relative fault of such indemnifying party and indemnified parties shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact, has been made by, or relates to information supplied by, such indemnifying party or indemnified parties, and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such action.

The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 7.3 were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to in the immediately preceding paragraph. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person.

8. Definitions. As used herein, the following terms shall have the following respective meanings:

"Beneficial Ownership" shall have the meaning set forth in Rule 13d-3 under the Exchange Act.

WHEREAS, the parties hereto desire to revise the Agreement to reflect that CoreComm will be merging directly into ATX as opposed to ATX Merger Sub merging into CoreComm;

NOW, THEREFORE, in consideration of the foregoing and the mutual covenants and agreements set forth herein and for other good and valuable consideration, the receipt and adequacy of which is hereby acknowledged, the parties hereto agree as follows:

Amendment to Section 1.1(f). Section 1.1(f) shall be deleted and replaced in its entirety with the following:

"At the Effective Time, the separate existence of CoreComm Merger Sub shall cease and CoreComm Merger Sub shall be merged (the "Merger") with and into ATX (ATX and CoreComm Merger Sub are sometimes referred to herein as the "Constituent Corporations" and ATX is sometimes referred to herein as the "Surviving Corporation"). The Certificate of Incorporation of ATX as in effect immediately prior to the Effective Time (as theretofore amended in accordance with Section 5.28 below) shall be the Certificate of Incorporation of the Surviving Corporation until thereafter amended as provided by the DGCL, and the Bylaws of ATX as in effect immediately prior to the Effective Time (as theretofore amended in accordance with Section 5.28 below) shall be the Bylaws of the Surviving Corporation until thereafter amended as provided by the DGCL, the Certificate of Incorporation and such Bylaws."

1. Amendment to Section 1.3. Section 1.3 shall be deleted and replaced in its entirety with the following:

"1.3 Conversion of CoreComm Common Stock. As of the Effective Time, by virtue of the Merger and without any action on the part of the holder of any

B-103

shares of ATX Common Stock or CoreComm's common stock, par value $.01 per share ("CoreComm Common Stock"):

(a) INTENTIONALLY OMITTED.

(b) All shares of CoreComm Common Stock that are owned by CoreComm as treasury stock or by any Subsidiary of CoreComm shall be canceled and retired and shall cease to exist and no consideration shall be delivered in exchange therefor. As used in this Agreement, the word "Subsidiary" means, with respect to any party, any corporation or other organization, whether incorporated or unincorporated, of which
(i) such party or any other Subsidiary of such party is a general partner (excluding partnerships, the general partnership interests of which held by such party or any Subsidiary of such party do not have a majority of the voting interest in such partnership) or (ii) at least a majority of the securities or other interests having by their terms ordinary voting power to elect a majority of the Board of Directors or others performing similar functions with respect to such corporation or other organization is directly or indirectly owned or controlled by such party or by any one or more of its Subsidiaries, or by such party and one or more of its Subsidiaries.

(c) Subject to Section 1.4, each issued and outstanding share of CoreComm Common Stock (other than shares to be canceled in accordance with Section 1.3(b) and shares to be issued under Section 1.3(a)) shall be converted into the right to receive one (1) (the "Merger Ratio") fully paid and nonassessable shares of ATX Common Stock. All such shares of CoreComm Common Stock, when so converted, shall no longer be outstanding and shall automatically be canceled and retired and shall cease to exist, and each holder of a certificate representing any such shares shall cease to have any rights with respect thereto, except the right to receive the shares of ATX Common Stock and any cash in lieu of fractional shares of ATX Common Stock to be issued or paid in consideration therefor upon the surrender of such certificate in accordance with Section 1.4."

2. Amendment to Section 1 of Amendment No. 1. Section 1 to Amendment No. 1 to the Recapitalization Agreement and Plan of Merger is hereby deleted in its entirety.

3. Amendment to Section 1.5. Section 1.5 shall be deleted and replace in its entirety with the following: "INTENTIONALLY OMITTED".

4. Amendment to Section 6.17. Section 6.17 of the Agreement is hereby deleted in its entirety.

5. General Amendment. Effective hereby, each reference in the Agreement to ATX Merger Sub which is no longer appropriate by virtue of the actions contemplated by this Amendment shall be considered ineffective and inapplicable and, accordingly, the Agreement shall be interpreted and enforced by the parties hereto as if ATX Merger Sub is not in existence and is not a party to this Agreement.

B-104

6. Other Provisions Unchanged. Except as specifically amended hereby, all other terms and conditions of the Agreement shall remain in full force and effect. To the extent that the Agreement includes such terms as "herein," "hereto," "in this Agreement" and the like, such terms shall be interpreted to refer to the Agreement, as modified by this Amendment.

7. Counterparts. This Amendment may be executed in separate counterparts, each of which shall be an original and all of which taken together shall constitute one and the same instrument.

AMENDMENT NO. 3
TO
RECAPITALIZATION AGREEMENT AND PLAN OF MERGER

This Amendment No. 3 to the Recapitalization Agreement and Plan of Merger (this "Amendment") is made and entered into July 31, 2000, by and between ATX Telecommunications Services, Inc., Thomas Gravina, Debra Buruchian, Michael Karp, The Florence Karp Trust, CoreComm Limited, ATX Merger Sub, Inc. and CoreComm Merger Sub, Inc. All capitalized terms which are used but not otherwise defined herein shall have meanings specified in the Agreement (as defined below), and all amendments thereto.

WHEREAS, CoreComm, CoreComm Merger Sub, ATX, ATX Merger Sub and the ATX Stockholders are parties to that certain Recapitalization Agreement and Plan of Merger, dated March 9, 2000, as amended by Amendment No. 1 to the Recapitalization Agreement and Plan of Merger, dated April 10, 2000, and by Amendment No. 2 to the Recapitalization Agreement and Plan of Merger, dated July 10, 2000 (the "Agreement"), pursuant to which ATX and CoreComm have agreed to combine in order to advance the long-term business interests of ATX and CoreComm; and

WHEREAS, the parties hereto desire to revise the Agreement to provide for certain changes to the terms of the Agreement.

NOW, THEREFORE, in consideration of the foregoing and the mutual covenants and agreements set forth herein and for other good and valuable consideration, the receipt and adequacy of which is hereby acknowledged, the parties hereto agree as follows:

1. Amendment to Section 1.2(a)(iii). Section 1.2(a)(iii) of the Agreement is hereby amended in its entirety to read as follows:

(iii) $150 million in cash (subject to certain adjustments set forth herein); provided, however, that CoreComm may, at its sole discretion, reduce the aggregate amount of cash to be paid by CoreComm to the ATX Stockholders to not less than $40 million (subject to certain adjustments set forth herein, the "Cash Consideration") and the balance of the $150 million payable under this subsection shall be paid through the issuance of notes with such terms and conditions as set forth in the term sheet attached hereto as Exhibit B (the "Senior Notes;" the combination of the Cash Consideration and Senior Notes payable hereunder being referred to as the "Notes and Cash Consideration;" the Notes and Cash Consideration, together with the ATX Common Stock and the ATX Convertible Preferred Stock, are collectively referred to as the "Exchange Consideration").(1) The adjustments set forth below to the contrary notwithstanding, if the result of the adjustments set forth below would be the payment to the ATX Stockholders of less than $40 million of the


1As described in Exhibit B, if Senior Notes are issued the principal amount thereof shall be increased by up to $9,000,000.

B-109

Notes and Cash Consideration in the form of cash (including adjustments pursuant to Section 1.2(j)), such adjustments shall, instead of reducing the Cash Consideration, reduce, on a dollar-for-dollar basis, the principal amount of Senior Notes to the extent that (but only to the extent that) the ATX Stockholders would be entitled to an increase in the Notes and Cash Consideration as a result of the Capital Expenditure Amount as of July 31, 2000 having been greater than $5,877,817. If such adjustment based on the Capital Expenditure Amount is greater than the reduction in cash, the excess of such adjustment shall be made by an increase in the principal amount of the Senior Notes. For avoidance of doubt, the intention of the parties is that any upward adjustment in the purchase price resulting from capital expenditures shall first be by way of a setoff against reductions of the cash consideration otherwise due in accordance with the adjustments below, and any excess over such reduction shall be by way of an increase in the principal amount of the Senior Notes.

2. Amendment to Section 1.2(b) through (i). Sections 1.2(b) through
(i) of the Agreement are hereby amended in their entirety to read as follows:

(b) ATX shall prepare as of the earlier of (x) the Closing Date and (y) August 31, 2000, an unaudited consolidated balance sheet (estimated as of the Closing Date or August 31, 2000, as the case may be) (the date as of which such balance sheet is dated being the "Target Date") and unaudited estimated statements of income and cash flows of ATX for the period from the ATX Balance Sheet Date to the Target Date (the "Estimated Target Date Financial Statements") from the GAAP Audited Financials and the books and records of ATX in accordance with GAAP (applied on a consistent basis using the same accounting methods, policies, practices, principles and procedures with consistent classifications, judgments and estimation methodologies used in preparation of the GAAP Audited Financials) and shall set forth the Working Capital as of the Target Date ("Estimated Target Date Working Capital"), the ATX Debt as of the Target Date (the "Estimated Target Date ATX Debt") and the estimated capital expenditures made by ATX and the ATX Partnerships during the period from the ATX Balance Sheet Date to July 31, 2000 (the "Estimated 7/31 Capital Expenditures Amount"). ATX shall prepare the Estimated Target Date Financial Statements as promptly as practicable, but in no event later than the earlier of (A) five (5) business days prior to the scheduled Closing Date, and (B) September 15, 2000. ATX shall provide a copy of the Estimated Target Date Financial Statements to CoreComm not later than three (3) days after its completion, and in any event at least two (2) business days prior to the scheduled Closing Date. If the Target Date is the Closing Date, ATX shall also deliver to CoreComm, together with the delivery of the Estimated Target Date Financial Statements, a detailed schedule of the distributions permitted by Section 1.2(j) hereof, if any, that it estimates will be made on or prior to the Closing Date (the "Estimated Closing Date Distributions"). If the Target Date is August 31, 2000

B-110

(and August 31, 2000 is not the Closing Date), not later than five (5)
business days prior to the scheduled Closing Date, ATX shall deliver to CoreComm a detailed schedule of the distributions permitted by Section 1.2(j) which (i) have actually been made subsequent to August 31, 2000 and prior to (but not including) the date of such schedule (the "Actual Distributions"), and (ii) ATX estimates will be made from the date of such schedule through the Closing Date (the "Estimated Additional Distributions;" the the Actual Distributions together with the Estimated Additional Distributions are together referred to as the "Estimated Distributions."

In the event that the Estimated Target Date Financial Statements reflect that the Estimated Target Date Working Capital is less than zero (such deficiency, the "Estimated Working Capital Shortfall"), then the Notes and Cash Consideration shall be reduced (subject to the calculation of the final Target Date Financial Statements) by an amount equal to the Estimated Working Capital Shortfall. Any such reduction shall be made as follows: the aggregate amount of Senior Notes to be issued as part of the Notes and Cash Consideration shall be reduced on a dollar-for-dollar basis by an amount equal to the lesser of $5 million and the amount of Estimated Working Capital Shortfall, and, if the Estimated Working Capital Shortfall exceeds $5 million, the Cash Consideration portion of the Notes and Cash Consideration shall be reduced by an amount equal to the amount by which the Estimated Working Capital Shortfall exceeds $5 million. If the Estimated Target Date Financial Statements reflect that the Estimated Target Date Working Capital is greater than zero (such excess, the "Estimated Working Capital Excess") then the Notes and Cash Consideration shall be increased (subject to the calculation of the final Target Date Financial Statements) by increasing the aggregate principal amount of Senior Notes to be issued at the Closing by an amount equal to the amount of the Estimated Working Capital Excess. The Estimated Working Capital Shortfall or Estimated Working Capital Excess, as applicable, shall be the "Estimated Target Date Working Capital Adjustment."

In the event that the Estimated Target Date Financial Statements reflect that Estimated Target Date ATX Debt is greater than zero, then the Notes and Cash Consideration shall be reduced (subject to the calculation of the final Target Financial Statements) by reducing the amount of the Cash Consideration portion of the Notes and Cash Consideration by an amount equal to the Estimated Target Date ATX Debt.

In the event that the Estimated Target Date Financial Statements reflect that the Estimated 7/31 Capital Expenditure Amount is less than $5,877,817 (the "Capital Expenditure Target Amount,") the Notes and Cash Consideration shall be reduced (subject to the calculation thereof based on the final Target Date Financial Statements) by reducing the aggregate principal amount of Senior Notes to be issued at the Closing by an amount equal to the difference between the Capital Expenditure Target Amount and the 7/31

B-111

Capital Expenditure Amount. In the event that the Estimated Target Date Financial Statements reflect that the 7/31 Capital Expenditure Amount is greater than the Capital Expenditure Target Amount, the Notes and Cash Consideration shall be increased (subject to the calculation thereof based on the final Target Date Financial Statements) by increasing the aggregate principal amount of Senior Notes to be issued at the Closing by an amount equal to the lesser of (i) $1,500,000, and
(ii) the difference between the Capital Expenditure Target Amount and the 7/31 Capital Expenditure Amount (the adjustments contemplated by this paragraph being the "Capital Expenditure Adjustment").

(c) Within ninety (90) days after the Closing Date (the "Financial Statements Delivery Date"), ATX shall cause to be prepared and delivered to the Stockholder Representative (as defined below) a proposed unaudited balance sheet and proposed unaudited statements of income and cash flows (the "Proposed Target Date Financial Statements") prepared in accordance with GAAP (applied on a consistent basis using the same accounting methods, policies, practices, principles and procedures with consistent classifications, judgments and estimation methodologies that were used in preparation of the GAAP Audited Financials) setting forth the Working Capital of ATX and ATX Debt as of the Target Date, and the Capital Expenditures of ATX and the ATX Partnerships for the period from (and excluding) the ATX Balance Sheet Date through (and including) July 31, 2000. For purposes of this
Section 1.2, the Stockholder Representative shall mean BDO Seidman, LLP. ATX shall also prepare and deliver to the Stockholder Representative at the same time as it delivers the Proposed Target Date Financial Statements, its calculation of the amount of the distributions made pursuant to Section 1.2(j) subsequent to the Target Date (the "ATX Distribution Calculation").

(d) The Stockholder Representative shall have a period of thirty
(30) days (the "Review Period") from the date on which ATX delivers the Proposed Target Date Financial Statements and the ATX Distribution Calculation to the Stockholder Representative pursuant to Section 1.2(c), to review the Proposed Target Date Financial Statements and the ATX Distribution Calculation. If, prior to the expiration of the Review Period, the Stockholder Representative does not deliver a Dispute Notice (as defined below) to ATX, the unaudited balance sheet and unaudited statements of income and cash flows included in the Proposed Target Date Financial Statements and the ATX Distribution Calculation shall be deemed to be final and binding upon ATX and the ATX Stockholders for purposes of determining the Working Capital of ATX, the ATX Debt as of the Target Date, the Capital Expenditures of ATX for the period from the ATX Balance Sheet Date through July 31, 2000 and the amount of the distributions made pursuant to Section 1.2(j) subsequent to the Target Date (the "Post-Target Date Distributions"). The unaudited balance sheet and unaudited statements of income and cash flows included in the Proposed Target Date Financial

B-112

Statements shall not become final and binding at the end of the Review Period, nor shall the ATX Distribution Calculation become final and binding if, prior to the expiration of the Review Period, the Stockholder Representative delivers a written notice to ATX (the "Dispute Notice") setting forth in reasonable detail the disagreements that the Stockholder Representative has with the unaudited balance sheet and/or either of the unaudited statements of income and cash flows included in the Proposed Target Date Financial Statements and/or with the ATX Distribution Calculation and the effect which such disagreements would have on the calculation of any of the Working Capital of ATX, the ATX Debt as of the Target Date, the Capital Expenditures of ATX for the period from the ATX Balance Sheet Date through July 31, 2000, the ATX Distribution Calculation or the amount (or form) of Notes and Cash Consideration payable to the ATX Stockholders. If the Stockholder Representative delivers a Dispute Notice prior to the end of the Review Period, the representatives of ATX and the Stockholder Representative shall have a ten (10) day period (the "Settlement Period") from the date of the delivery of the Dispute Notice to attempt to resolve any dispute set forth in the Dispute Notice and to agree upon an unaudited balance sheet and unaudited statements of income and cash flows and/or upon the amount of the Post-Target Date Distributions, which shall be binding on ATX and the ATX Stockholders for purposes of this Agreement and to agree upon the Working Capital of ATX, the ATX Debt as of the Target Date, the Capital Expenditures of ATX for the period from the ATX Balance Sheet Date through July 31, 2000 and the Post-Target Date Distributions. If the Stockholder Representative and ATX have not arrived at an agreement during the Settlement Period, then, at any time following the termination of the Settlement Period, either the Stockholder Representative or ATX may submit the issue in dispute to the Philadelphia, Pennsylvania office of PricewaterhouseCoopers LLP (the "Accountant") for resolution in accordance with this Section. In resolving any disputed item, the Accountant (i) shall be bound by the provisions of this Section 1.2, (ii) may not assign a value to any item greater than the greatest value for such item claimed by either party or less than the smallest value for such item claimed by either party,
(iii) shall make its determination based solely on information submitted by the parties and not by independent review and (iv) shall be instructed to issue a report containing its resolution of the disputed issue or issues (the "Accountant's Report") within thirty (30) days following submission of the dispute. The Accountant's Report shall be delivered by the Accountant to ATX and the Stockholder Representative, and shall be final and binding on ATX and the ATX Stockholders for purposes of this Agreement. The fees charged by the Accountant shall be paid by ATX.

(e) During the period of any dispute within the contemplation of this Section 1.2, the ATX Stockholders, the Stockholder Representative and their representatives (including counsel and accountants) shall have reasonable access during normal business hours to all books, records, employees, offices

B-113

and other facilities and properties of the Surviving Corporation to the extent required to complete their review of the Target Date Financial Statements and their examination of the calculations with respect to the ATX Distribution Calculation and shall be permitted to review the working papers (subject to the execution of customary waivers, releases and indemnifications), if any, of ATX or its auditor relating to the Target Date Financial Statements or the ATX Distribution Calculation; provided that any such access shall not unreasonably interfere with the day-to-day operations of ATX and shall be limited to those items related to the assessment of the Target Date Financial Statements or the ATX Distribution Calculation, as the case may be, and matters related thereto. ATX and CoreComm or their auditors shall cooperate with the ATX Stockholders and other representatives of the ATX Stockholders in facilitating such review.

(f) In the event that the final Target Date Financial Statements reflect that the Working Capital of ATX as of the Target Date is less than zero (such deficiency, the "Final Working Capital Shortfall"), then the Notes and Cash Consideration shall be reduced by an amount equal to the excess of zero over the Final Working Capital Shortfall (the "Final Shortfall"); provided, however, that the Final Shortfall shall be adjusted to reflect any adjustments to the Notes and Cash Consideration previously made due to an Estimated Target Date Working Capital Adjustment. Any such reduction shall be made to by reducing the Cash Consideration and/or the Notes to the same extent as they would have been reduced had the Final Shortfall been used at the Closing rather than the Estimated Working Capital Adjustment. If the Final Target Date Balance Sheet reflects that the Working Capital of ATX as of the Target Date is greater than zero (a "Final Working Capital Excess") then the Notes and Cash Consideration shall be increased by issuing additional Senior Notes to the ATX Stockholders in an aggregate amount equal to the excess of the Final Working Capital Excess over the amount of Working Capital generated subsequent to July 31, 2000; provided, however, that the Final Working Capital Excess (and any related amounts to be paid) shall be adjusted to reflect any adjustments to the Notes and Cash Consideration previously made due to an Estimated Target Date Working Capital Adjustment.

(g) In the event that the final Target Date Financial Statements reflect that the ATX Debt is greater than zero (such amount the "Final ATX Debt"), then the Notes and Cash Consideration shall be decreased by reducing the Cash Consideration portion of the Notes and Cash Consideration as provided in Section 1.2(i); provided, however, that the Final ATX Debt shall be adjusted to reflect any adjustments to the Closing Exchange Consideration previously made due to any Estimated Target Date ATX Debt.

(h) In the event that the final Target Date Financial Statements reflect that the capital expenditures made by ATX during the period from the ATX Balance Sheet Date to July 31, 2000 (the "7/31 Capital Expenditure

B-114

Amount") is less than the Estimated 7/31 Capital Expenditure Amount, then the Notes and Cash Consideration shall be decreased by decreasing the aggregate principal amount of Senior Notes by an amount equal to the excess of the Estimated 7/31 Capital Expenditure Amount over the 7/31 Capital Expenditure Amount; provided, however, if the Estimated 7/31 Capital Expenditure Amount was an amount in excess of $1,500,000 over the Capital Expenditure Target Amount, then, for purposes of the calculation required by this subsection (h), the Estimated 7/31 Capital Expenditure Amount shall be deemed to have been an amount equal to $1,500,000 over the Capital Expenditure Target Amount. For purposes of
Section 1.2, the 7/31 Capital Expenditure Amount shall include only amounts paid or payable by ATX prior to the Target Date which have been purchased and installed by ATX on or prior to July 31, 2000.

(i) In the event of any reduction to the Notes and Cash Consideration occurring after the Closing by operation of Subsections
(f) through (h) above which involves a reduction in the Cash Consideration, the ATX Stockholders shall be jointly and severally liable to pay to ATX in cash the amount in question. In the event of any reduction of the Notes and Cash Consideration occurring after the Closing by operation of Subsections (f) through (h) above which involves a reduction in the aggregate principal amount of the Senior Notes, ATX shall be entitled to cause each of the Senior Notes to be reduced by its pro-rata portion of such amount; provided, however, that in lieu of having the principal amount of any Senior Note reduced, the ATX Stockholder who originally received the indebtedness evidenced by such Senior Note may deliver to ATX a personal note having the same interest rate, payment and maturity dates as the Senior Notes in an amount equal to the amount which such ATX Stockholder's Senior Note would have been reduced; provided further, however, that such personal notes may only be delivered in respect of such ATX Stockholder's ratable share of $5,000,000. For purposes hereof, an ATX Stockholder's ratable share shall mean a fraction, the numerator of which is the aggregate principal amount of Senior Notes actually issued to such ATX Stockholder at the Closing (without giving effect to any post-Closing adjustment thereof pursuant to Sections 1.2(f) through (h) hereof) and the denominator of which is the aggregate amount of all Senior Notes actually issued to the ATX Stockholders at the Closing (without giving effect to any post-Closing adjustment thereof pursuant to Sections 1.2(f) through (h) hereof).

3. Amendments to Section 1.2(j). Section 1.2(j) of the Agreement is amended as follows:

(a) The period at the end of clause (ii) of Section 1.2(j) is deleted and a semicolon is inserted in lieu thereof followed by the word "or."

B-115

(b) A new clause (iii) is added following clause (ii) and reading as follows:

(iii) pay fees and expenses of ATX in connection with the transactions contemplated by this Agreement (such fees and expenses include any and all investment banking, legal, accounting and similar fees and expenses payable by ATX in connection with the transactions contemplated hereby).

(c) The following additional language is inserted following (but not as part of) clause (iii):

The Notes and Cash Consideration shall be reduced by reducing the Notes and Cash Consideration by an amount equal to any distribution made in accordance with this Section 1.2(j), such reductions being made as follows: the amount of Notes and Cash Consideration, and the portion thereof constituting the Cash Consideration, shall be reduced on a dollar for dollar basis by an amount equal to the Estimated Distributions permitted to be made pursuant to clauses (i) and (ii) of this Section 1.2(j); and the amount of Notes and Cash Consideration, and the portion thereof payable in Senior Notes, shall be reduced on a dollar for dollar basis by an amount equal to the Estimated Distributions that constitute distributions permitted to be made pursuant to clause
(iii) of this Section 1.2(j). If the distributions permitted to be made pursuant to clauses (i) and (ii) of this Section 1.2(j) exceeds the amount of the Estimated Distributions in respect thereof, ATX shall be entitled to be paid, and the ATX Stockholders shall be jointly and severally liable to pay to ATX, an amount in cash equal to the amount by which the actual amount of the distributions permitted to be made pursuant to such clauses
(i) and (ii) exceeds the amount of the Estimated Distributions in respect thereof. If the distributions permitted to be made pursuant to clause (iii) of this Section 1.2(j) exceeds the amount of the Estimated Distributions in respect thereof, ATX shall be entitled to cause each of the Senior Notes to be reduced by its pro-rata portion of the actual amount of the distributions permitted to be made pursuant to such clause (iii) to the extent that such amount exceeds the amount of the Estimated Distributions in respect thereof. The foregoing notwithstanding, any payment made subsequent to August 31, 2000 by ATX to any ATX Stockholder to the extent that such payment constitutes the repayment of funds advanced in cash by such ATX Stockholder to ATX subsequent to August 31, 2000 in order to fund ATX's working capital requirements for the period following August 31, 2000 through the Closing Date shall not be reflected in any purchase price adjustment and ATX shall make such reimbursements, if not already made, at or prior to the Closing Date. Anything in this Section 1.2(j) to the contrary notwithstanding, under no circumstances

B-116

may the aggregate amount of all distributions permitted by this
Section 1.2(j) exceed $25,000,000.

13. Amendment to Exhibits. Exhibits A, B, C and G to the Agreement are hereby superseded and replaced in their entirety with Exhibits A, B, C and G attached hereto, respectively.

14. Proxy Statement. Subject to obtaining the approval thereof of all parties in interest, CoreComm shall use its reasonable best efforts to cause an amended Schedule 14A relating to the transactions contemplated by the Agreement to be filed with the Securities and Exchange Commission within three (3) business days following the execution and delivery of this Amendment by all parties hereto. As soon as practicable following the filing of a definitive proxy statement with the Securities and Exchange Commission, having due regard for the rules and policies of the Securities and Exchange Commission, CoreComm will mail definitive proxy materials to its stockholders and will convene a meeting of its shareholders to consider the transactions contemplated by the Agreement not later than 30 days following the date of mailing of the definitive proxy materials to the CoreComm stockholders.

15. Conduct in the Ordinary Course. ATX acknowledges that notwithstanding the fact that the working capital adjustment provided for in Section 1.2 of the Agreement shall be based on working capital of ATX as of August 31, 2000 (if the Closing Date is subsequent to August 31, 2000), ATX shall continue to be obligated to conduct its business as required by
Section 5.3 of the Agreement until the Closing Date; provided, however that the ATX Stockholders and their Affiliates may make advances to ATX to fund ATX's working capital requirements in the ordinary course consistent with past practices, which advances shall not be deemed to constitute a breach of Section 5.3 of the Agreement.

16. Financing Terms. If CoreComm undertakes its proposed bank and its proposed Rule 144a financing prior to Closing, such financing shall be completed on terms which are not materially different from, in a manner materially adverse to CoreComm, the terms heretofore described to the ATX Stockholders. If either such financing is completed on terms materially different from those described to the ATX Stockholders, and such differences are materially adverse to CoreComm, CoreComm shall immediately notify the ATX Stockholders of such event, and absent a waiver by the ATX Stockholders of such noncompliance, CoreComm shall not be permitted to borrow under the Senior Notes described herein, and the remainder of this amendment shall remain in full force and effect. "Materially different" shall be considered to be any adverse modification to any term of such financings by at least 15% (other than the amount of each type of financing), which

B-119

may not be increased. The foregoing bank financing must be one comprehensive financing, including the syndication thereof. The intent is that CoreComm will enter the market to obtain one bank financing arrangement to be completed at one time in an amount between $100 million and $200 million. It is not contemplated that CoreComm will do two or more separate bank financings that do not close simultaneously. However, nothing herein is intended to limit CoreComm's ability to structure such bank financing in a customary manner, including, but not limited to, multiple tranches, staggered drawing and other standard provisions. In addition, upon delivery to the ATX Stockholders of a term sheet reasonably acceptable to the ATX Stockholders, the foregoing provisions (and their counterparts in Exhibit B) shall be deemed to apply to a bridge financing in addition to the bank and 144a financings. Such bridge financing will be subject to the same constraints described herein (and in Exhibit B) that apply to the bank and 144a financings.

17. Stock Option Plan; etc. Not later than seven (7) business days following the date of this Amendment, CoreComm shall deliver to ATX a proposal outlining employee stock option arrangements for ATX as well as term sheets outlining employment and/or consulting services to be provided to CoreComm by Thomas Gravina and Debra Buruchian subsequent to the Closing.

18. Letter of Credit. CoreComm shall cause to be posted a letter of credit, not to exceed $900,000, which shall be absolute and unconditional supporting ATX's leasehold obligations in respect of the rental of approximately 25,000 square feet of office space located in Bala Cynwyd, Pennsylvania. If this Agreement shall be terminated under conditions which would result in ATX being obligated to repay any capital expenditure advances made by CoreComm pursuant to Section 5.34 of the Agreement, without regard to any changes made herein, then ATX shall be obligated to take all actions necessary in order to promptly and effectively relieve CoreComm of any liability which it may have in respect of such letter of credit. In the event that the Agreement is terminated and ATX occupies the office space under such lease for at least 30 days following such termination, then ATX shall be required to replace CoreComm on the letter of credit.

19. Other Provisions Unchanged. Except as specifically amended hereby, all other terms and conditions of the Agreement shall remain in full force and effect. To the extent that the Agreement includes such terms as "herein," "hereto," "in this Agreement" and the like, such terms shall be interpreted to refer to the Agreement, as modified by this Amendment.

20. Counterparts. This Amendment may be executed in separate counterparts, each of which shall be an original and all of which taken together shall constitute one and the same instrument.

Annex D

DELAWARE GENERAL CORPORATION LAW

SEC.262. APPRAISAL RIGHTS.

(a) Any stockholder of a corporation of this State who holds shares of stock on the date of the making of a demand pursuant to subsection (d) of this section with respect to such shares, who continuously holds such shares through the effective date of the merger or consolidation, who has otherwise complied with subsection (d) of this section and who has neither voted in favor of the merger or consolidation nor consented thereto in writing pursuant to sec.228 of this title shall be entitled to an appraisal by the Court of Chancery of the fair value of the stockholder's shares of stock under the circumstances described in subsections (b) and (c) of this section. As used in this section, the word "stockholder" means a holder of record of stock in a corporation and also a member of record of a nonstock corporation; the words "stock" and "share" mean and include what is ordinarily meant by those words and also membership or membership interest of a member of a nonstock corporation; and the words "depository receipt" mean a receipt or other instrument issued by a depository representing an interest in one or more shares, or fractions thereof, solely of stock of a corporation, which stock is deposited with the depository.

(b) Appraisal rights shall be available for the shares of any class or series of stock of a constituent corporation in a merger or consolidation to be effected pursuant to sec.251 (other than a merger effected pursuant to sec.251(g) of this title), sec.252, sec.254, sec.257, sec.258, sec.263 or sec.264 of this title:

(1) Provided, however, that no appraisal rights under this section shall be available for the shares of any class or series of stock, which stock, or depository receipts in respect thereof, at the record date fixed to determine the stockholders entitled to receive notice of and to vote at the meeting of stockholders to act upon the agreement of merger or consolidation, were either (i) listed on a national securities exchange or designated as a national market system security on an interdealer quotation system by the National Association of Securities Dealers, Inc. or (ii) held of record by more than 2,000 holders; and further provided that no appraisal rights shall be available for any shares of stock of the constituent corporation surviving a merger if the merger did not require for its approval the vote of the stockholders of the surviving corporation as provided in subsection (f) of sec.251 of this title.

(2) Notwithstanding paragraph (1) of this subsection, appraisal rights under this section shall be available for the shares of any class or series of stock of a constituent corporation if the holders thereof are required by the terms of an agreement of merger or consolidation pursuant to sec.sec.251, 252, 254, 257, 258, 263 and 264 of this title to accept for such stock anything except:

a. Shares of stock of the corporation surviving or resulting from such merger or consolidation, or depository receipts in respect thereof;

D-1

b. Shares of stock of any other corporation, or depository receipts in respect thereof, which shares of stock (or depository receipts in respect thereof) or depository receipts at the effective date of the merger or consolidation will be either listed on a national securities exchange or designated as a national market system security on an interdealer quotation system by the National Association of Securities Dealers, Inc. or held of record by more than 2,000 holders;

c. Cash in lieu of fractional shares or fractional depository receipts described in the foregoing subparagraphs a. and b. of this paragraph; or

d. Any combination of the shares of stock, depository receipts and cash in lieu of fractional shares or fractional depository receipts described in the foregoing subparagraphs a., b. and c. of this paragraph.

(3) In the event all of the stock of a subsidiary Delaware corporation party to a merger effected under sec.253 of this title is not owned by the parent corporation immediately prior to the merger, appraisal rights shall be available for the shares of the subsidiary Delaware corporation.

(c) Any corporation may provide in its certificate of incorporation that appraisal rights under this section shall be available for the shares of any class or series of its stock as a result of an amendment to its certificate of incorporation, any merger or consolidation in which the corporation is a constituent corporation or the sale of all or substantially all of the assets of the corporation. If the certificate of incorporation contains such a provision, the procedures of this section, including those set forth in subsections (d) and
(e) of this section, shall apply as nearly as is practicable.

(d) Appraisal rights shall be perfected as follows:

(1) If a proposed merger or consolidation for which appraisal rights are provided under this section is to be submitted for approval at a meeting of stockholders, the corporation, not less than 20 days prior to the meeting, shall notify each of its stockholders who was such on the record date for such meeting with respect to shares for which appraisal rights are available pursuant to subsection (b) or (c) hereof that appraisal rights are available for any or all of the shares of the constituent corporations, and shall include in such notice a copy of this section. Each stockholder electing to demand the appraisal of such stockholder's shares shall deliver to the corporation, before the taking of the vote on the merger or consolidation, a written demand for appraisal of such stockholder's shares. Such demand will be sufficient if it reasonably informs the corporation of the identity of the stockholder and that the stockholder intends thereby to demand the appraisal of such stockholder's shares. A proxy or vote against the merger or consolidation shall not constitute such a demand. A stockholder electing to take such action must do so by a separate written demand as herein provided. W
