THE COMPANY

GTS is a provider of a broad range of telecommunications services to businesses, other telecommunications service providers and consumers in Russia, the Commonwealth of Independent States ("CIS") and Central Europe. Through its subsidiary Hermes Europe Railtel B.V. ("HER"), GTS is developing, and operating the initial segments of, a pan-European high capacity fiber optic network that is designed to interconnect a majority of the largest Western and Central European cities and to transport international voice, data and multimedia/image traffic for other carriers throughout Western and Central Europe. GTS's strategy to develop its businesses generally has been to establish joint ventures with a strong local partner or partners while maintaining a significant degree of operational control. The Company's business activities consist of the ownership and operation of (i) international long distance businesses, which operate through international gateways that provide international switching services and transmission capacity, (ii) local access networks, which provide local telephone service, (iii) cellular networks, which provide wireless telecommunications services, (iv) a domestic long distance business, (v) data networks and (vi) carriers' carrier networks, which provide high volume transmission capacity to other carriers.

In Russia and the CIS, GTS's objective is to become the premier alternative telecommunications operator. To attain its objective, the Company has partnered with regional telephone companies and with Rostelecom, the national long distance carrier in Russia. The Company currently operates in 24 oblasts (regions) and the city of Moscow in Russia, as well as in 11 additional cities in the CIS, and believes it is well-positioned to become the leading independent telecommunications service provider in Russia. These businesses include: (i) EDN Sovintel ("Sovintel"), which provides Moscow, and recently St. Petersburg, with international long distance and local telephone services and access to the major domestic long distance carriers; (ii) TeleCommunications of Moscow ("TCM"), which provides local access services in Moscow; (iii) TeleRoss (as defined herein), which provides domestic long distance services in fourteen cities in Russia, including Moscow, as well as Very Small Aperture Terminal ("VSAT") service to customers outside its primary long distance satellite network; (iv) Sovam Teleport ("Sovam"), which provides data services, including high-speed data transmission, electronic mail, Internet access services, as well as Russia On Line, the first Russian language Internet service; and (v) the Company's cellular operations ("GTS Cellular"), which operate cellular networks in twelve regions in Russia and also in Kiev, Ukraine, with licenses covering regions with an aggregate population of approximately 25 million people at the end of 1996. Whenever practical, GTS's businesses integrate and co-market their service offerings in Russia and the CIS, utilizing TeleRoss as the domestic long distance provider, Sovintel as the international gateway, TCM and GTS Cellular for local access, and Sovam as the data communications and Internet access network for business applications and on-line services. Together, GTS's Russian and CIS ventures carried 202.5 million and 291.3 million minutes of traffic for the year ended December 31, 1996 and the nine months ended September 30, 1997, respectively, and had approximately 24,600 customers, including approximately 16,300 cellular subscribers, as of September 30, 1997. See "Business -- Russia and the CIS."

In Western Europe, GTS seeks to position itself as the leading independent carriers' carrier through the development of two ventures, HER and GTS-Monaco Access S.A.M. ("GTS-Monaco Access"). HER's objective is to become the leading pan-European carriers' carrier by providing centrally managed cross-border telecommunications transmission capacity to telecommunications companies including traditional Public

Telecommunications Operators ("PTOs") and new entrants, such as alternative carriers, global consortia of telecommunications operators, international carriers, Internet backbone networks, resellers, value-added networks and other service providers ("New Entrants") on an approximately 18,000 kilometer high capacity fiber optic network designed to interconnect a majority of the largest Western and Central European cities. HER is currently operating over an approximately 1,700-kilometer portion of the network linking Brussels, Antwerp, Rotterdam, Amsterdam, London and Paris. HER expects to roll out full telecommunications transport service over approximately 2,900 kilometers of fiber optic cable linking the cities of London, Rotterdam, Amsterdam, Antwerp, Brussels, Paris, Dusseldorf and Frankfurt (the "initial five country network") in the second quarter of 1998. The full 18,000 kilometer network is expected to become fully operational during the year 2000. HER also plans to lease capacity on a transatlantic cable linking the European network to North America and is exploring various interconnectivity options to Russia and Asia. Such intercontinental interconnectivity will help HER satisfy the needs of its European customers with respect to outgoing traffic and attract additional non-European customers with traffic terminating in Europe. HER commenced commercial service over the Brussels-Amsterdam portion of the network in late 1996 and the London-Paris portion in November 1997. GTS-Monaco Access operates an international gateway in Monaco in partnership with, and utilizing the existing gateway infrastructure of, the Principality of Monaco and provides transit and routing of international calls to other telecommunications operators. Through its HER and GTS-Monaco Access ventures, GTS is building a new network for transporting voice, data and multimedia/image traffic for other carriers throughout Western and Central Europe and for worldwide international voice, data and multimedia/image traffic that either originates or terminates in, or transits through, Western and Central Europe. See "Business -- Western Europe."

In Central Europe, GTS's objective is to become one of the leading alternative telecommunications providers in the region. GTS currently provides private data communications services to government and commercial customers in Hungary and the Czech Republic. In the Czech Republic, the Company provides outgoing voice services and operates an international gateway and a data services network. In Hungary, GTS operates a VSAT network, which GTS believes is the largest VSAT network in Central Europe as measured by number of VSAT sites. The Company has also signed an agreement to provide international data services in Poland, subject to the receipt of necessary governmental approvals. GTS's strategy is to expand its service offerings as the regulatory environment permits, leverage its existing VSAT and international gateway infrastructure where possible and provide a broad range of services to its target markets.

Although GTS does not currently own or operate significant telecommunication assets in Asia, GTS's objective is to become an established and diversified telecommunications provider in China and India. GTS seeks to leverage its position in these countries to capitalize on opportunities as they arise.

BUSINESS STRATEGY

GTS seeks to develop businesses to meet the rapidly expanding market demand for telecommunications services. GTS's goal in emerging markets is to establish itself as the leading alternative to the incumbent telecommunications service providers and as a premier provider of value-added services. In addition, the Company seeks to position itself as the leading independent carriers' carrier within Western and Central Europe through the development of a pan-European fiber optic network and an international gateway in Monaco.

GTS believes that it will be able to successfully operate its businesses and develop business opportunities by pursuing the following strategies:

- Identify and Seize Early Market Opportunities. GTS's primary strategy is to identify less developed markets in which the incumbent operator offers inadequate service and where liberalization of telecommunications regulations may be pending. The Company believes that entering these less developed markets quickly is a key competitive advantage in the global telecommunications market. GTS leverages its management's knowledge of the markets in which the Company operates to assess and react quickly when attractive business opportunities arise.

- Establish Joint Ventures with Experienced Local Partners. GTS seeks to establish and maintain strategic partnerships and relationships with key telecommunications operators and service providers in the countries in which it operates. The Company believes that these relationships increase its ability to anticipate and respond to changes in the regulatory and legal environment and assist with license renewal and expansion of its operating companies.

- Retain Significant Operational Control. In general, GTS actively participates in the management of its ventures by (i) providing most of the funding for the ventures' operations, (ii) selecting key members of the local management team, (iii) developing business plans and marketing strategies together with local management, (iv) monitoring operating functions, (v) maintaining close working relationships with local partners and (vi) integrating its networks and businesses in a manner which is consistent with the Company's overall strategic objectives.

- Build Infrastructure to Provide High Quality Services. GTS continues to develop and expand its network infrastructure. The Company believes that its networks offer service, quality and cost advantages over incumbent providers as a result of the Company's customer support, network monitoring, management systems and its ability to integrate and co-market its service offerings.

- Leverage Management Depth and Experience. GTS's management has significant experience in the development and operation of telecommunications businesses outside the United States. The Company believes that this experience, together with the Company's extensive operations, has provided its management with the ability to identify, evaluate and pursue international telecommunications business opportunities. Additionally, GTS has assembled a management team comprised of executives with extensive experience managing telecommunications companies in the respective local markets. GTS believes that its management team possesses a broad knowledge of relevant political and regulatory structures, as well as the cultural awareness and fluency with international and local business practices necessary to implement the Company's objectives.

- Ability to Access Capital. In general, the Company's financing strategy is to establish parent level funding to meet general corporate needs and the costs of start-ups and acquisitions and, when it is possible and cost-effective, to finance ongoing operations at the venture level. Since 1993, the Company has raised approximately $268 million in equity and approximately $215 million of debt (of which approximately $74 million was raised through shareholders). In addition, HER completed a $265 million private placement of senior notes (of which $56.5 million was placed into escrow for the first two years' interest payments) in 1997. The Company's principal investors include affiliates of George Soros and Alan B. Slifka and certain of his affiliates.

In addition to its overall business strategy, GTS has developed specific market strategies to achieve its goals in emerging markets and Western Europe.

Emerging Markets. The Company pursues its goals in emerging markets through a three-stage approach of market entry, market expansion and market integration.

- Market Entry. GTS identifies a market as a suitable target for entry based upon: (i) superior growth prospects for such market, demonstrated by growing demand for high quality telecommunications services; (ii) the provision of inadequate services by incumbent providers, typically resulting from the incumbents' unwillingness to offer high quality services with reliable customer support at attractive prices; and (iii) attractive regulatory environments in which emerging alternative telecommunications providers such as GTS have, or expect to have over a clearly defined time horizon, the ability to compete on a substantially equal basis with the incumbent providers in terms of certain services and the cost of providing those services. Once GTS has identified a market as suitable for entry, the Company seeks to establish its presence in that market by establishing a venture with a strong local partner or partners. In general, GTS maintains a significant degree of operational control in such ventures. Through such ventures, the Company benefits from its partners' ability to provide infrastructure, regulatory expertise and personnel that will provide GTS with a competitive advantage in entering that market. When entering a new market, GTS's strategy is to provide its customers with higher quality service as compared to the services offered by incumbent providers.

- Market Expansion. Having entered a market successfully and established a limited service offering to its targeted customer base, GTS then seeks to expand the range of services it offers to existing and potential customers and to further develop its relationships with local partners. By broadening its service offerings, GTS anticipates achieving increased economies of scale through the common use of administrative and operating functions already in place, increasing the Company's share of its customers' telecommunications spending and expanding GTS's base of potential customers through the provision of a bundled service offering. The Company also seeks to expand its targeted geographic market by forming new partnerships, installing infrastructure and offering services in additional geographic regions, allowing the Company to further enhance its operating leverage and ability to service its customers' telecommunications needs.

- Market Integration. GTS ultimately intends to integrate and co-market its service offerings in each of the markets in which it operates. The Company believes such integration enables it to enhance its operating efficiency by leveraging its distribution channels, infrastructure and networks, and management information systems. As customers develop a need for a broader variety of telecommunications services, the Company believes GTS's integrated operations will represent an attractive service alternative for customers seeking a single provider with the ability to meet all their telecommunications needs.

Western Europe. The Company seeks to position itself as the leading independent carriers' carrier within Western Europe through the development of HER's pan-European fiber optic network and the operation of GTS-Monaco Access's international gateway in partnership with, and utilizing the gateway infrastructure of, the Principality of Monaco. The overall strategy of GTS in Western Europe is to complement and enhance the services provided by PTOs and New Entrants in a way that helps them to more successfully meet the needs of their end-user customers. HER seeks to enter the market ahead of competition and encourage a wide variety of carriers to use its network with service offerings that meet their needs. To establish itself as the leading carriers' carrier for international telecommunications within Europe, HER intends to provide its customers with significantly higher quality transmission and advanced network capabilities at a competitive price by utilizing advanced, uniform technology across the region and providing redundant routing for higher levels of reliability.

FINANCING PLAN

In general, the Company's strategy is to finance general corporate cash needs, the development of start-up ventures and acquisitions through the parent company and, when possible and cost effective, to finance ongoing operations at the venture level. Since 1993, the Company has raised approximately $268 million in equity and approximately $215 million of debt (of which approximately $74 million was raised through shareholders). In addition, HER completed a $265 million private placement of senior notes (of which $56.5 million was placed into escrow for the first two years' interest payments) in 1997.

Concurrently with the Notes Offering, the Company is undertaking the Stock Offerings, which offerings will be made by separate prospectuses. The consummation of both the Note Offering and the Stock Offerings are conditioned upon the consummation of the other.

The Company believes that the net proceeds from the Offerings, together with existing cash, will be sufficient to fund its expected capital needs until at least June 1999. GTS expects that it may require additional capital to execute its current business plan and to fund expected operating losses, as well as to consummate future acquisitions and exploit opportunities to expand and develop its businesses. Management expects that GTS and its ventures will incur over $515 million of capital expenditures during the next three years, of which approximately $235 million will be incurred in 1998. Of these amounts, approximately $290 million will be used to fund construction of the HER network, with approximately $35 million required for the roll out of the initial five country network that is expected to be completed in the second quarter of 1998. The Company also will need to fund operating losses of its ventures for at least the next 12 months. In addition, as part of its business strategy, the Company regularly evaluates potential acquisitions and joint ventures. The Company has no definitive agreement with respect to any acquisition or joint venture, although from time to time it has discussions with other companies and assesses opportunities on an on-going basis. The Company may fund these acquisitions or joint ventures with a portion of the net proceeds from the Offerings. See "Risk Factors -- Additional Capital Requirements" and "Management's Discussion and Analysis of Financial Condition and Results of Operations -- Liquidity and Capital Resources."

As of September 30, 1997, after giving effect to the Stock Offerings, certain affiliates of George Soros, Alan B. Slifka and certain affiliates, and certain affiliates of Capital Research International are expected to own approximately 20.4%, 10.8% and 10.1% of the Common Stock on a fully-diluted basis, respectively. See "Principal Stockholders."

                                         defined) for the benefit of the holders
                                         of the Notes. The Company will grant to
                                         the Trustee for the benefit of the
                                         holders of the Notes, a first priority
                                         and exclusive security interest in the
                                         Escrow Account and the proceeds
                                         thereof. Funds will be disbursed from
                                         the Escrow Account for interest
                                         payments (but not additional interest)
                                         on the Notes. Upon acceleration of the
                                         maturity of the Notes, the Escrow
                                         Agreement will provide for the payment
                                         of the amount remaining in the Escrow
                                         Account to the Trustee to be applied on
                                         account of amounts owing on the Notes
                                         as provided in the Indenture. Pending
                                         such disbursement, all funds contained
                                         in the Escrow Account will be invested
                                         in Cash Equivalents (as defined). See
                                         "Description of Notes -- Escrow

Change of Control...................     Upon the occurrence of a Change of
                                         Control, each holder of the Notes may
                                         require the Company to repurchase such
                                         holder's Notes, in whole or in part, at
                                         a purchase price in cash equal to 101%
                                         of their principal amount plus accrued
                                         and unpaid interest, if any, to any
                                         repurchase date. The failure of the
                                         Company to repurchase Notes of any
                                         holder exercising such right will
                                         constitute an Event of Default. See
                                         "Description of the Notes -- Change of
                                         Control."

                                         unsecured debt obligations of the
                                         Company. The Company is a holding
                                         company which conducts its operations
                                         entirely through its subsidiaries and
                                         affiliates. The Notes will be
                                         effectively subordinated to all
                                         liabilities of the Company's
                                         subsidiaries and affiliates. The
                                         Indenture dated as of             ,
                                         1998 between the Company and The Bank
                                         of New York, as trustee (the
                                         "Trustee"), under which the Notes will
                                         be issued will permit the incurrence or
                                         issuance by Restricted Group Members
                                         (as defined) of the Company of
                                         substantial additional indebtedness.
                                         The aggregate amount of outstanding
                                         obligations of the Company's Restricted

                                         approximately $[     ] as of September
                                         30, 1997. See "Description of the
                                         Notes -- Ranking."

Certain Covenants...................     The Indenture contains covenants that,
                                         among other restrictions, limit the
                                         ability of the Company and the

SUMMARY HISTORICAL CONSOLIDATED FINANCIAL DATA

The following summary historical consolidated financial data as of December 31, 1996 and September 30, 1997 and for the years ended December 31, 1994, 1995 and 1996 and for the nine months ended September 30, 1997 are derived from the Company's audited Consolidated Financial Statements. The following unaudited summary historical consolidated financial data for the nine months ended September 30, 1996 are derived from the Company's unaudited Consolidated Financial Statements. The summary historical consolidated financial data presented below should be read in conjunction with "Management's Discussion and Analysis of Financial Condition and Results of Operations," and the audited Consolidated Financial Statements and related notes thereto appearing elsewhere in this Prospectus.

Under generally accepted accounting principles, a majority of the Company's ventures are accounted for by the equity method of accounting. Under this method, the operating results of the ventures are included in the Company's Consolidated Statement of Operations as a single line item, "Equity in losses of ventures." The Company recognizes 100% of the losses in ventures where the Company bears all of the financial risk (which includes all of the Company's significant ventures except for Sovintel and, historically, HER). Also, the assets, liabilities and equity of the ventures are included in the Company's Consolidated Balance Sheets as a single line item, "Investments in and advances to ventures." See Note 2 to the Company's audited Consolidated Financial Statements and "Management's Discussion and Analysis of Financial Condition and Results of Operations -- Overview." Financial information about the Company's equity ventures is included below under "Supplemental Information -- Summary Historical Financial Data -- Equity Investments."

(1) As a result of the Company's increase in ownership interest and amendment to the HER Shareholders Agreement that was completed on July 16, 1997, the Company accounts for its ownership interest in HER under the consolidation method of accounting. Prior to this date, the Company accounted for HER using the equity method of accounting.

(2) Because of the Company's historic losses, the Company has experienced a deficiency of earnings available to cover fixed charges throughout its existence. The deficiency of earnings available to cover fixed charges has been computed by adding loss from continuing operations before income taxes minus undistributed earnings of associated companies and fixed charges. Fixed charges consist of interest on all indebtedness and amortization of discount on all indebtedness.

RISK FACTORS

ADDITIONAL CAPITAL REQUIREMENTS

GTS expects that it may require additional capital to execute its current business plan and to fund expected operating losses, as well as to consummate future acquisitions and exploit opportunities to expand and develop its businesses. Management expects that GTS and its ventures will incur over $515 million of capital expenditures during the next three years, of which approximately $235 million will be incurred in 1998. Of these amounts, approximately $290 million will be used to fund construction of the HER network, with approximately $35 million required for the roll out of the initial five country network that is expected to be completed in the second quarter of 1998. The Company also will need to fund operating losses of its ventures for at least the next 12 months. In addition, as part of its business strategy, the Company regularly evaluates potential acquisitions and joint ventures. The Company has no definitive agreement with respect to any material acquisition or joint venture, although from time to time it has discussions with other companies and assesses opportunities on an on-going basis. The Company may fund such acquisitions or joint ventures with a portion of the net proceeds from the Offerings.

The Company believes that the net proceeds from the Offerings, together with existing cash, will be sufficient to fund its expected capital needs until at least June 1999. The actual amount and timing of the Company's future capital requirements, however, may differ materially from management's estimates. In particular, the accuracy of management's estimates are subject to changes and fluctuations in the Company's revenues, operating costs and development expenses, which can be affected by the Company's ability to (i) effectively and efficiently manage the expansion of the HER network and operations, (ii) obtain infrastructure contracts, rights-of-way, licenses and other regulatory approvals necessary to complete and operate the HER network, (iii) negotiate favorable contracts with suppliers, including large volume discounts on purchases of capital equipment and (iv) access markets, attract sufficient numbers of customers and provide and develop services for which customers will subscribe. The Company's revenues and costs are also dependent upon factors that are not within the Company's control such as regulatory changes, changes in technology, increased competition and various factors such as strikes, weather, and performance by third-parties in connection with the Company's operations. Due to the uncertainty of these factors, actual revenues and costs may vary from expected amounts, possibly to a material degree, and such variations are likely to affect the Company's future capital requirements. Historically, GTS has experienced liquidity problems resulting in part from the Company's need to meet the capital requirements of certain of its joint ventures in excess of forecast amounts. In addition, certain of the Company's joint ventures have not met management's financial performance expectations or have not been able to secure local country financing and thus have not been able to generate the expected cash inflows. In addition, if the Company expands its operations at an accelerated rate or consummates acquisitions, the Company's funding needs will increase, possibly to a significant degree, and it will expend its capital resources sooner than currently expected. The Company may also be required to repay its Convertible Bonds upon maturity in the year 2000 to the extent such bonds are not converted into Common Stock. As a result of the foregoing, or if the Company's capital resources otherwise prove to be insufficient, the Company may need to raise additional capital. See "-- Government Regulation," "-- Competition," "-- Technology," "-- HER Network Roll-out," "Management's Discussion and Analysis of Financial Condition and Results of Operations," and "Use of Proceeds."

If the Company decides to raise additional funds through the incurrence of debt, it may become subject to additional or more restrictive financial covenants and its interest obligations will increase. If the Company decides to raise additional funds through the issuance of equity, the interests of holders of the Common Stock, will be diluted. There can be no assurance that additional financing will be available to GTS on favorable terms or at all, and failure to generate sufficient funds in the future, whether from operations or by raising additional debt or equity capital, may require the Company to delay or abandon some or all of its anticipated expenditures, to sell assets, or both, and could affect the Company's ability to compete, either of which could have a material adverse effect on the operations of the Company, and could affect the value of the Notes. See "Management's Discussion and Analysis of Financial Condition and Results of Operations" and "Use of Proceeds."

12

SUBSTANTIAL LEVERAGE

GTS is, and will continue to be, highly leveraged as a result of the substantial indebtedness it has incurred and intends to incur to pursue the implementation of its business plans. On a pro forma consolidated basis, after giving effect to the issuance of the Notes, the Company would have had approximately $533.7 million aggregate principal amount of indebtedness outstanding at September 30, 1997. GTS's debt instruments permit the Company and its subsidiaries to incur certain additional indebtedness to fund expansion of the Company's businesses and for other permitted purposes. The degree to which the Company is leveraged could have important consequences for holders of the Notes, including (i) limiting the Company's ability to refinance its existing indebtedness or obtain additional financing to fund future working capital, capital expenditures and other general corporate requirements, (ii) requiring the dedication of a substantial portion of the Company's cash flow from operations to the payment of principal of, and interest on, its indebtedness, thereby reducing the availability of such cash flow to fund working capital, capital expenditures or other general corporate purposes, (iii) limiting the Company's flexibility in planning for, or reacting to, changes in its business and the telecommunications industry, (iv) limiting the Company's ability to obtain additional financing to make capital expenditures and acquisitions, (v) limiting the Company's ability to withstand adverse economic conditions or take advantage of significant business opportunities that may arise, (vi) limiting the Company's ability to invest in new or developing technologies, (vii) limiting the Company's ability to respond to changes affecting the implementation of its financing, construction or operating plans and (viii) placing the Company at a competitive disadvantage with respect to less-leveraged competitors. In addition, the Company's operating and financial flexibility will be limited by covenants contained in agreements governing the indebtedness of the Company. Among other things, these covenants limit or may limit the ability of the Company and its subsidiaries to incur additional indebtedness, make capital expenditures, pay dividends or make distributions on capital stock of the Company or make certain other restricted payments, create certain liens upon assets, dispose of certain assets or enter into certain transactions with affiliates. There can be no assurance that such covenants will not materially and adversely affect the Company's ability to finance its future operations or capital needs or to engage in other business activities which may be in the interest of the Company.

The Company must substantially increase its net cash flow in order to meet its debt service obligations, and there can be no assurance that the Company will be able to meet such obligations, including the obligations of the Company under the Notes. If the Company is unable to generate sufficient cash flow or otherwise obtain funds necessary to make required payments, or if it otherwise fails to comply with the various covenants under its indebtedness, it would be in default under the terms thereof, which would permit the holders of such indebtedness to accelerate the maturity of such indebtedness and could cause defaults under other indebtedness of the Company, including the Notes. Such defaults could result in a default on the Notes and could delay or preclude payments of interest or principal thereon.

RANKING; UNSECURED STATUS OF THE NOTES

The Notes will represent unsecured, senior obligations of the Company, and will rank senior in right of payment to all subordinated indebtedness of the Company and at least pari passu in right of payment with all other present and future unsecured, senior indebtedness of the Company. On September 30, 1997, on a pro forma consolidated basis after giving effect to the Notes Offering, GTS would have had approximately $533.7 million of total indebtedness, of which $433.7 million ($450.1 million on a combined basis) would have ranked senior to the Notes. The Notes will be effectively subordinated to all indebtedness of the Company's subsidiaries and joint ventures. On September 30, 1997, the Company's equity investees had $16.4 million of indebtedness. Although the Indenture will limit the ability of the Company and its subsidiaries to incur additional indebtedness, the Company may incur significant amounts of indebtedness pursuant to certain exceptions in the Indenture. In the event of a bankruptcy, liquidation or reorganization of the Company or any default in the payment of any indebtedness under any senior secured credit facility or other secured indebtedness, holders of such secured indebtedness will be entitled to payment in full from the proceeds of all assets of the Company pledged to secure such indebtedness prior to any payment of such proceeds to holders

13

of the Notes. Consequently, there can be no assurance that the Company will have sufficient funds to make payments to holders of the Notes. See "Description of the Notes."

HOLDING COMPANY STRUCTURE; SIGNIFICANT LIMITATIONS ON ACCESS TO SUBSIDIARIES' AND JOINT VENTURES' CASH FLOW

GTS is a holding company which has no significant business operations or assets other than its interests in joint ventures and its subsidiaries. Accordingly, GTS must rely entirely upon distributions from the joint ventures and its subsidiaries and investments to generate the funds necessary to meet its obligations, including payments on the Notes. The joint ventures and the Company's subsidiaries are separate and distinct legal entities which have no obligation, contingent or otherwise, to pay any amount due pursuant to the Notes or to make any funds available therefor, whether by dividends, loans or other payments. In addition, should the Company receive dividends or other distributions from its joint ventures, subsidiaries or investments, the ability of the Company to repatriate such profits and capital is dependent upon the provisions of the applicable foreign investment and exchange laws and availability of foreign exchange in sufficient quantities in those countries. The amount of such dividends and other distributions from these entities will be affected by the current tax systems in these jurisdictions, primarily the provisions relating to corporate profits and withholding taxes. See "-- Taxes; Availability of Net Operating Loss Carryforwards." Furthermore, because consent is required of the joint venture partners in some of the Company's joint ventures for distributions from such joint ventures, the Company's ability to receive dividends and other distributions is to some degree dependent on cooperation from its joint venture partners. See "-- Dependence on Certain Local Parties; Absence of Control." Thus, there can be no assurance that the Company will be able to realize benefits from its joint ventures, subsidiaries and investments through the receipt of dividends or other distributions at such times and amounts it desires. Any failure by GTS to receive dividends or other distributions from its joint ventures, subsidiaries or investments would restrict the Company's ability to repay the Notes and could otherwise have a material adverse effect on the Company's business, results of operations and financial condition. In the event that the Company were unable to meet its working capital needs and capital expenditure requirements with cash generated from operations or borrowings from other sources, the Company would have to consider various options, such as refinancing outstanding indebtedness, obtaining additional equity capital or selling certain assets. There can be no assurance that the Company will be able to raise new equity capital, refinance its outstanding indebtedness, or obtain new financing in the future, or that, if the Company is able to do so, the terms available will be favorable to the Company. See "Management's Discussion and Analysis of Financial Condition and Results of Operations -- Liquidity and Capital Resources."

ABILITY TO SERVICE DEBT; ABILITY TO REPURCHASE NOTES UPON A CHANGE OF CONTROL

In the event of a Change of Control (as defined herein), each holder of outstanding Notes may require the Company to repurchase all or a portion of such holder's Notes. The ability of the Company to make payments in connection with such redemptions or repurchases, and the ability of the Company to meet its debt service obligations generally, including its principal and interest obligations under the Notes, will depend on the future operating performance and financial results of the Company. There can be no assurance that the cash generated from operations, together with any cash available from any financing alternatives and asset sales, will allow the Company to meet its debt service obligations, including its obligations with respect to the Notes. In the event the Company is unable to make such payments out of cash generated from operations, it would need to consider various alternatives such as refinancing the Notes, raising additional equity capital or selling certain assets.

HISTORY OF OPERATING LOSSES

The Company has historically sustained substantial operating and net losses. The Company had net losses of $0.4 million in 1992, $2.4 million in 1993, $12.0 million in 1994, $40.4 million in 1995, $68.0 million in 1996 and $87.9 million for the nine months ended September 30, 1997. The Company's cumulative net losses totalled $213.8 million from inception through September 30, 1997. Further development of the Company's business will require significant additional expenditures and the Company expects that it will have significant operating and net losses and will record significant net cash outflow, before financing, in coming years. There

14

can be no assurance that the Company's operations will achieve or sustain profitability or positive cash flow in the future. If the Company cannot achieve and sustain operating profitability or positive cash flow from operations, it may not be able to meet its debt service obligations or working capital requirements. See "Management's Discussion and Analysis of Financial Condition and Results of Operations."

HER NETWORK ROLL-OUT

HER's ability to achieve its strategic objective will depend in large part on the successful, timely and cost-effective completion of the HER network. Although HER currently operates commercially over an approximately 1,700 kilometer portion of the network linking Brussels, Antwerp, Rotterdam, Amsterdam, London and Paris, the development of the remainder of the network may be delayed or adversely affected by a variety of factors, uncertainties and contingencies. Many of these factors, such as strikes, natural disasters and other casualties, are beyond HER's control. In addition, HER will need to negotiate and conclude additional agreements with various parties regarding, among other things, rights-of-way and development and maintenance of the network infrastructure and equipment. Historically, HER has experienced substantial delays in concluding these agreements and developing its network. There can be no assurance that HER will be successful in concluding necessary agreements, or that delays in concluding such agreements will not materially and adversely affect the speed or successful completion of the network. The successful and timely completion of the network will also depend on, among other things, (i) the availability to HER of substantial amounts of additional capital and financing, (ii) timely performance by various third parties of their contractual obligations to engineer, design and construct portions of the network and (iii) HER's ability to obtain and maintain applicable governmental approvals.

HER expects to roll out full telecommunications service over the initial five country network in the second quarter of 1998, and the 18,000 kilometer network to be operational during the year 2000. Although HER believes that its cost estimates and the build-out schedule are reasonable, there can be no assurance that the actual construction costs or time required to complete the network build-out will not substantially exceed current estimates.

Any significant delay or increase in the costs associated with development of the HER network could have a material adverse effect on HER and the Company.

Development of the HER network is capital intensive. Management expects that approximately $290 million in capital expenditures will be incurred in connection with the buildout of the HER network, with approximately $35 million required for the roll out of the initial five country network that is expected to be completed in the second quarter of 1998. While HER raised approximately $265 million in a private placement of its senior notes in August 1997 (of which $56.5 million has been placed in escrow for the first two years' interest payments on the notes), additional financing must be obtained to construct the HER network and there can be no assurance that such additional financing will be completed. Failure to obtain necessary financing may require HER to delay or abandon its plans for deploying the remainder of the network and would adversely affect the viability of HER, or may require the Company to make additional capital contributions to HER at the expense of the Company's other operations, either of which could have a material adverse effect on the operations of the Company. HER's revenues and the cost of deploying its network and operating its business will depend upon a variety of factors including, among other things, HER's ability to (i) effectively and efficiently manage the expansion of its network and operations, (ii) negotiate favorable contracts with suppliers, (iii) obtain additional licenses, regulatory approvals, rights-of-way and infrastructure contracts to complete and operate the network, (iv) access markets and attract sufficient numbers of customers and (v) provide and develop services for which customers will subscribe. HER's revenues and costs are also dependent upon factors that are not within HER's control such as regulatory changes, changes in technology, increased competition and various factors such as strikes, weather and performance by third-parties in connection with the development of the network. Due to the uncertainty of these factors, actual costs and revenues may vary from expected amounts, possibly to a material degree, and such variations would likely affect HER's future capital requirements. See "Management's Discussion and Analysis of Financial Condition and Results of Operations -- Liquidity and Capital Resources." HER must obtain additional infrastructure provider agreements for the long-term lease of dark fiber, rights-of-way and other permits to install fiber optic

15

cable from railroads, utilities and governmental authorities to build out the network. There can be no assurance that HER will be able to maintain all of its existing agreements, rights and permits or to obtain and maintain the additional agreements, rights and permits needed to implement its business plan on acceptable terms. Loss of substantial agreements, rights and permits or the failure to enter into and maintain required arrangements for the HER network could have a material adverse effect to enter on HER's business. In addition, HER depends on third parties for leases of dark fiber for substantial portions of its network. There can be no assurance that HER will be able to enter into and maintain required arrangements for leased portions of the HER network, which could have a material adverse effect on HER's business.

In order to operate and, in the case of some countries, even to construct the network in accordance with current plans, HER must obtain the necessary regulatory approvals. To date, HER has obtained licenses, authorizations and/or registrations in the United Kingdom, the Netherlands, Belgium, Germany and France and has obtained a trial concession to operate in Switzerland. In addition, HER intends to file applications in other countries in anticipation of service launch in accordance with the HER network roll-out plan. The terms and conditions of these licenses, authorizations or registrations may limit or otherwise affect HER's scope of operations. There can be no assurance that HER will be able to obtain, maintain or renew licenses, authorizations or registrations to provide the services it currently provides and plans to provide, that such licenses, authorizations or registrations will be issued or renewed on terms or with fees that are commercially viable, or that the licenses, authorizations or registrations required in the future can be obtained by HER. The loss of, or failure to obtain, these licenses, authorizations or registrations or a substantial limitation upon the terms of these licenses, authorizations or registrations could have a material adverse effect on HER. See "Business -- Western Europe -- HER -- Licenses and Regulatory Issues."

RISKS RELATING TO REORGANIZATION OF RUSSIAN TELECOMMUNICATIONS INDUSTRY

Svyazinvest was established by the Russian government in 1994 to hold the government's interest in 88 regional telecommunication companies. In April 1997, President Yeltsin approved the transfer of additional government-owned telecommunications assets, including the government's 51% stake in Rostelecom (the government controlled international and long distance operator), to Svyazinvest. On July 30, 1997, Mustcom Ltd., a Cyprus-based company that represents the interests of a consortium which includes ICFI Cyprus, Renaissance International Ltd., Deutsche Morgan Grenfell, Morgan Stanley, and an affiliate of George Soros, purchased a 25% stake in Svyazinvest for $1.87 billion. As of September 30, 1997, affiliates of George Soros beneficially owned 25.8% of the Company's Common Stock. The President has also authorized the sale of another 24% of Svyazinvest at a future date. This sale is scheduled to occur in the first half of 1998 and is currently reserved solely for Russian investors. The Russian government has announced that it will retain a controlling 51% interest in Svyazinvest. As a result of the government's actions, a single entity, Svyazinvest, now owns a majority interest in most of the Company's principal venture partners and other telecommunication service providers in Russia which together provide a range of international and domestic long distance and local telecommunications services throughout Russia. The consolidation of many of its partners under Svyazinvest and the possible sale of a significant interest in Svyazinvest to foreign and/or Russian investors will likely subject the Company to more coordinated competition from Svyazinvest, and may lead to material adverse changes in the business relationships between the Company and such partners, which business relationships represent a material component of the Company's business strategy in Russia. There can be no assurance that the continuing privatization of Svyazinvest, or the evolution of government policy regarding Svyazinvest and Rostelecom, will not have a material adverse effect on the Company or its ventures. See "-- Competition," "-- Dependence on Certain Local Parties; Absence of Control" and "Business -- Russia and the CIS -- Overview" and "Principal Stockholders."

MANAGING RAPID GROWTH

As a result of the Company's past and expected continued growth and expansion, significant demands have been placed on the Company's management, operational and financial resources and on its systems and controls. The Company continues to construct segments of the HER network, expand its operations within Russia and the CIS and expand into additional geographic and service markets when business and regulatory conditions warrant. In order to manage its growth effectively, the Company must continue to implement and

16

improve its operational and financial systems and controls, purchase and utilize additional telecommunications facilities and expand, train and manage its employee base. Inaccuracies in the Company's forecasts of market demand could result in insufficient or excessive telecommunications facilities and disproportionate fixed expenses for certain of its operations. There can be no assurance that the Company will be able to construct and operate the entire HER network as currently planned, expand with the markets in which its ventures are currently operating or expand into additional markets at the rate presently planned by the Company, or that any existing regulatory barriers to such expansion will be reduced or eliminated. As the Company proceeds with its development and expansion, there will be additional demands on the Company's customer support, sales and marketing and administrative resources and network infrastructure. There can be no assurance that the operating and financial control systems and infrastructure of the Company and its ventures will be adequate to maintain and effectively manage future growth. The failure to continue to upgrade the administrative, operating and financial control systems or the emergence of unexpected expansion difficulties could materially and adversely affect the Company's business, results of operations and financial condition.

RISKS RELATING TO EMERGING MARKETS

Substantially all of the Company's revenue is derived from operations in emerging markets, where the Company's businesses are subject to numerous risks and uncertainties, including political, economic and legal risks, such as unexpected changes in regulatory requirements, tariffs, customs, duties and other trade barriers, difficulties in staffing and managing foreign operations, problems in collecting accounts receivable, political risks, fluctuations in currency exchange rates, foreign exchange controls which restrict or prohibit repatriation of funds, technology export and import restrictions or prohibitions, delays from customs brokers or government agencies, seasonal reductions in business activity, and potentially adverse tax consequences resulting from operating in multiple jurisdictions with different tax laws, which could materially adversely impact the Company's business, results of operations and financial condition.

The political systems of many of the emerging market countries in which the Company operates or plans to operate are slowly emerging from a legacy of totalitarian rule. Political conflict and, in some cases, civil unrest and ethnic strife may continue in some of these countries for a period of time. Many of the economies of these countries are weak, volatile and reliant on substantial foreign assistance. Expropriation of private businesses in such jurisdictions remains a possibility, whether by an outright taking or by confiscatory tax or other policies. There can be no assurance that GTS's operations will not be materially and adversely affected by such factors or by actions to expropriate or seize its operations. The success of free market reforms undertaken in certain of the emerging market countries in which the Company operates is also uncertain, and further economic instability may occur. These factors may reduce and delay business activity, economic development and foreign investment.

Legal systems in emerging market countries frequently have little or no experience with commercial transactions between private parties. The extent to which contractual and other obligations will be honored and enforced in emerging market countries is largely unknown. Accordingly, there can be no assurance that difficulties in protecting and enforcing rights in emerging market countries will not have a material adverse effect upon GTS and its operations. Additionally, the Company's businesses operate in uncertain regulatory environments. The laws and regulations applicable to GTS's activities in emerging market countries are in general new and subject to change and, in some cases, incomplete. There can be no assurance that local laws and regulations will become stable in the future, or that changes thereto will not materially adversely affect the operations of GTS. Additionally, telecommunications regulations in the more developed Western European markets in which GTS participates are currently undergoing changes initiated by the Commission of the European Union. See "Business."

RISKS RELATING TO RUSSIA AND THE CIS

Substantially all of the Company's revenue is derived from operations in Russia and the CIS. Foreign companies conducting operations in the former Soviet Union face significant political, economic, and legal risks.

17

Political. The political systems of Russia and the other independent countries of the CIS, which are in a stage of relative infancy, are vulnerable to instability due to the populace's dissatisfaction with reform, social and ethnic unrest and changes in government policies. Such instability could lead to events that could have a material adverse effect on the Company's operations in these countries. In recent years, Russia has been undergoing a substantial political transformation. During this transformation, legislation has been enacted to protect private property against expropriation and nationalization. However, due to the lack of experience in enforcing these provisions in the short time they have been in effect and due to potential political changes in the future, there can be no assurance that such protections would be enforced in the event of an attempted expropriation or nationalization. Expropriation or nationalization of the Company, its assets or portions thereof, whether by an outright taking or by confiscatory tax or other policies potentially without adequate compensation, would have a material adverse effect on the Company.

The various government institutions and the relations between them, as well as the government's policies and the political leaders who formulate and implement them, are subject to rapid and potentially violent change. For example, the Constitution of the Russian Federation gives the President of the Russian Federation substantial authority, and any major changes in, or rejection of, current policies favoring political and economic reform by the President may have a material adverse effect on the Company. Furthermore, the political and economic changes in Russia have resulted in significant dislocations of authority. The local press and international press have reported that significant organized criminal activity has arisen and high levels of corruption among government officials exist where the Company operates. While the Company does not believe it has been adversely affected by these factors to date, no assurance can be given that organized or other crime will not in the future have a material adverse effect on the Company.

Economic. Over the past five years the Russian government has enacted reforms to create the conditions for a more market-oriented economy. Despite some progress in implementing its reforms, including progress in reducing inflation and stabilizing the currency and industrial production, there remains generally rising unemployment and underemployment, high government debt relative to gross domestic product and high levels of corporate insolvency. No assurance can be given that reform policies will continue to be implemented and, if implemented, will be successful, that Russia will remain receptive to foreign trade and investment or that the economy will improve.

In addition, Russia, the CIS and other emerging countries in which the Company operates currently receive substantial financial assistance from several foreign governments and international organizations. To the extent any of this financial assistance is reduced or eliminated, economic development in Russia, the CIS and such other countries may be adversely affected.

Russian and CIS businesses have a limited operating history in market-oriented conditions. The relative infancy of the business culture is reflected in the Russian banking system's under-capitalization and liquidity crises. There have been concerns about rumors that many Russian banks continue to have cash shortages. The Russian Central Bank has reduced banks' reserve requirements in order to inject more liquidity into the Russian financial system, but has stressed that it will not bail out the weaker banks. Many of these banks are expected to disappear over the next several years as a result of bank failure and anticipated consolidation in the industry. A general Russian banking crisis could have a material adverse effect on the Company's operations and financial performance and on the viability of the Company's receivables.

Regulation of the Telecommunications Industry. The Russian telecommunications system is currently regulated largely through the issuance of licenses. There is currently no comprehensive legal framework with respect to the provision of telecommunications services in Russia, although a number of laws, decrees and regulations govern or affect the telecommunications sector. As a result, ministry officials have a fairly high degree of discretion to regulate the industry. Although telecommunication licenses may not be transferred under Russian law, the Russian Ministry of Communications (the "MOC") has adopted the position that licensees may enter into agreements with third parties in connection with the provision of services under the licensee's license; however, the MOC does not generally review agreements entered into by licensees. There can be no assurances that the current or future regulation of the Russian telecommunications systems will not have a material adverse effect on the Company.

18

Current Russian legislation governing foreign investment activities does not prohibit or restrict foreign investment in the telecommunications industry. However, on February 28, 1997, the State Duma, the lower house of parliament, approved, on the first reading, draft foreign investment legislation which would restrict any significant future foreign investment in numerous sectors of the Russian economy, including telephone and radio communications. It is unlikely that such restrictive legislation will be enacted, unless the political climate changes dramatically. See "-- Political." More likely is the emergence of restrictions on foreign investment in strategic industries, which could result in foreign ownership limitations in industries such as telecommunications which are not uncommon in many countries. The draft legislation has been referred to the Russian government for comment. For such draft legislation to become Federal law, it must be passed by a majority vote of the State Duma at another two readings, then be approved by a majority of the Federation Council, the upper house of parliament, and signed by the President of the Russian Federation. Rejection of such legislation by the Federation Council can be overridden by a two-thirds majority of the State Duma. Rejection of such legislation by the President can be overridden by a two-thirds majority of each of the Federation Council and the State Duma. There can be no assurance that future regulation of foreign investment in the telecommunications industry will not have a material adverse effect on the Company.

In addition, a lack of consensus exists over the manner and scope of government control over the telecommunications industry. Because the telecommunications industry is widely viewed as strategically important to Russia, there can be no assurance that recent government policies liberalizing control over the telecommunications industry will continue. Any change in or reversal of such governmental policies could have a material adverse effect on the Company. See "Business -- Russia and CIS -- Licenses and Regulatory Issues."

Legal Risks. As part of the effort to transform their economies into more market-oriented economies, the Russian and other CIS governments have rapidly introduced laws, regulations and legal structures intended to give participants in the economy a greater degree of confidence in the legal validity and enforceability of their obligations. Risks associated with the legal systems of Russia and the other independent republics of the CIS include (i) the untested nature of the independence of the judiciary and its immunity from economic, political or nationalistic influence; (ii) the relative inexperience of judges and courts in commercial dispute resolutions and generally in interpreting legal norms; (iii) inconsistencies among laws, presidential decrees, government resolutions and ministerial orders; (iv) frequently conflicting local, regional and national laws, rules and regulations; (v) the lack of legislative, judicial or administrative guidance on interpreting the applicable rules; and (vi) a high degree of discretion on the part of government authorities and arbitrary decision making which increases, among other things, the risk of property expropriation. The result has been considerable legal confusion, particularly in areas such as company law, commercial and contract law, securities and antitrust law, foreign trade and investment law and tax law. Accordingly, there can be no assurance that the Company will be able to enforce its rights in any disputes with its joint venture partners or other parties in Russia or the CIS or that its ventures will be able to enforce their respective rights in any disputes with partners, customers, suppliers, regulatory agencies or other parties in Russia or that the Company can be certain that it will be found to be in compliance with all applicable laws, rules and regulations.

Russia has adopted currency and capital transfer regulations designed to prevent the flight of capital from its borders. These regulations require certain licenses for the movement of capital, which includes the incurrence and repayment of indebtedness and the payment of capital contributions in foreign exchange to Russian entities. The Company is resolving licensing issues with respect to certain intercompany loans and capital contributions with the applicable government agencies and believes that any licensing irregularities that may arise will not have a material adverse effect on its financial condition or results of operations. There can be no assurance, however, that Russian government authorities will not take an unexpected adverse position which could materially adversely affect the Company's business.

Taxes. Generally, taxes payable by Russian companies are substantial. In addition, taxes payable by Russian companies are numerous and include taxes on profits, revenue, assets and payroll as well as value-added tax ("VAT"). Moreover, statutory tax returns of Russian companies are not consolidated and therefore, each company must pay its own Russian taxes. Because there is no consolidation provision, dividends are subject to Russian taxes at each level. Currently, dividends are taxed at 15% and the payor is required to

19

withhold the tax when paying the dividend, except with respect to dividends to foreign entities that qualify for an exemption under treaties on the avoidance of double taxation. To date, the system of tax collection has been relatively ineffective, resulting in the continual imposition of new taxes in an attempt to raise government revenues. This history, plus the existence of large government budget deficits, raises the risk of a sudden imposition of arbitrary or onerous taxes, which could adversely affect the Company.

Because of uncertainties associated with the laws and regulations of the Russian tax system and the increasingly aggressive interpretation, enforcement and collection activities of the Russian tax authorities, the Company's Russian taxes may be in excess of the estimated amount expensed to date and accrued on the Company's balance sheets. It is the opinion of management that the ultimate resolution of the Company's Russian tax liability, to the extent not previously provided for, will not have a material adverse effect on the financial condition of the Company. However, depending on the amount and timing of an unfavorable resolution of this contingency, it is possible that the Company's future results of operations or cash flows could be materially affected in a particular period.

In various foreign jurisdictions, the Company is obligated to pay VAT on the purchase or importation of assets, and for certain other transactions. In many instances, VAT can be offset against VAT which the Company collects and otherwise would remit to the tax authorities, or may be refundable. Because the law in some jurisdictions is unclear, the local tax authorities could assert that the Company is obligated to pay additional amounts of VAT. In the opinion of management, any additional VAT which the Company may be obligated to pay would not be material.

ADEQUACY OF MANAGEMENT, LEGAL AND FINANCIAL CONTROLS IN EMERGING MARKETS

Many of the emerging market countries in which the Company operates, particularly in Russia and the CIS where the Company has to date derived most of its revenues, are deficient in management and financial reporting concepts and practices, as well as in modern banking, computer and other control systems. The Company historically has had difficulty in hiring and retaining a sufficient number of qualified employees to work in these markets. As a result of these factors, the Company has experienced difficulty in establishing management, legal and financial controls, collecting financial data and preparing financial statements, books of account and corporate records and instituting business practices that meet Western standards.

The Company has a policy worldwide of complying with all applicable laws and seeks to ensure that all persons in its employ comprehend and comply with such laws. The application of the laws of any particular country, however, is not always clear, particularly in emerging market countries where commercial practices differ significantly from practices in the United States and other Western countries and the legal and regulatory frameworks are less developed. In addition, some practices, such as the payment of fees for the purpose of obtaining expedited customs clearance and other commercial benefits, that may be common methods of doing business in these markets might be unlawful under the laws of the United States. As a result of the difficulty the Company historically has experienced in emerging markets in instituting business practices that meet Western reporting and control standards, it historically has been unable to ascertain whether certain practices by its ventures, which were not in accordance with Company policy, were in compliance with applicable U.S. and foreign laws. If it were to be determined that the Company or any of its ventures were involved in unlawful practices and were the factual and legal issues relating thereto to be resolved adversely, the Company or its ventures could be exposed, among other things, to significant fines, risk of prosecution and loss of its licenses. See "-- Risks Relating to Emerging Markets" and "-- Government Regulation."

In light of these circumstances, in the second half of 1996 the Company increased its efforts to improve its management and financial controls and business practices. The Company recruited a more experienced financial and legal team, including a new Chief Financial Officer of the Company, a senior finance officer overseeing all of the regions in which the Company operates, a senior finance officer for the CIS region, and a senior legal officer for the CIS region. The Company also established a Treasury group and adopted a more rigorous Foreign Corrupt Practices Act ("FCPA") compliance program. The Company has developed and implemented a training program for employees regarding U.S. legal and foreign local law compliance. The Company also appointed a Compliance Officer responsible for monitoring compliance with such laws and

20

training Company personnel around the world. In connection with these developments, the Company expanded its corporate business practices policy to include, in addition to compliance with U.S. laws such as the FCPA, compliance with applicable local laws such as the conflict of interest rules under the 1996 Russian Joint Stock Company Law, currency regulations and applicable tax laws.

In early 1997, the Company retained special outside counsel to conduct a thorough review of certain business practices of the Company in the emerging markets in which the Company operates in order to determine whether deficiencies existed that needed to be remedied. As a result of this review, the Company replaced certain senior employees in Russia and instituted additional and more stringent management and financial controls. As a result of the review, the Company has not identified any violations of law that management believes would have a material adverse effect on the Company's financial condition. There can be no assurances, however, that if the Company or any of its ventures were found by government authorities to have committed violations of law that, depending on the penalties assessed and the timing of any unfavorable resolution, the Company's future results of operations and cash flows would not be materially adversely affected in a particular period.

Although the Company believes that this review was properly conducted and was sufficient in scope, there can be no assurance that all potential deficiencies have been identified or that the control procedures and compliance programs initiated by the Company will be effective. If the Company or any of its ventures are ever found to have committed violations of law, depending on the penalties assessed and the timing of any unfavorable resolution, the Company's future results of operations and cash flows could be materially adversely affected in a particular period. Management believes, however, that the actions taken during the past twelve months to strengthen the Company's management, financial controls and legal compliance, coupled with the implementation of the recent recommendations from the review and the oversight provided through the Audit Committee of the Board of Directors of the Company to ensure compliance, will be adequate to address the recurrence of any past possible deficiencies.

DEPENDENCE ON CERTAIN LOCAL PARTIES; ABSENCE OF CONTROL

Many GTS operations including Sovintel, TeleRoss and GTS Cellular have been developed in cooperation or partnership with key local parties, such as regional PTOs. The Company is substantially dependent on its local partners to provide marketing expertise and knowledge of the local regulatory environment in order to facilitate the acquisition of necessary licenses and permits. Any failure by the Company to form or maintain alliances with local partners, or the preemption or disruption of such alliances by the Company's competitors or otherwise, could adversely affect the Company's ability to penetrate and compete successfully in the emerging markets it operates in or enters. In addition, in the uncertain legal environments in which GTS operates, certain GTS businesses may be vulnerable to local government agencies or other parties who wish to renegotiate the terms and conditions of, or terminate, their agreements or other understandings with GTS.

While the Company may have the right to nominate key employees, direct the operations and determine the strategies of such joint ventures, under the terms of their respective constituent documents, the Company's partners in some of the ventures have the ability to frustrate the exercise of such rights. Significant actions by most of GTS's ventures, such as approving budgets and business plans, declaring and paying dividends, and entering into significant corporate transactions effectively require the approval of GTS's local partners. Further, the Company would be unlikely as a practical matter to want to take significant initiatives without the approval of its joint venture partners. Accordingly, the absence of unilateral control by the Company over the operations of its joint ventures could have a material adverse effect on the Company.

In addition, the Company and its venture partners frequently compete in the same markets. For example, Rostelecom, GTS's partner in Sovintel, is the dominant international and domestic long distance carrier in Russia. In addition, many of the regional telephone companies partnered with GTS in the TeleRoss Ventures offer cellular services in direct competition with certain of the operations of GTS Cellular. Such competition with its partners may lead to conflicts of interest for GTS and its partners in the operations of their ventures. There can be no assurance that any such conflicts will be resolved in favor of GTS. In addition, the

21

combination under Svyazinvest of the Russian government's majority interest in Rostelecom and 85 of the regional telephone companies gives Svyazinvest a majority interest in entities that provide international and domestic long distance and local telecommunications services throughout Russia and may expose the Company to more coordinated competition from its partners in the Russian telecommunications market. See "-- Risks Relating to Reorganization of Russian Telecommunications Industry."

GOVERNMENT REGULATION

As a multinational telecommunications company, GTS through its ventures is subject to varying degrees of regulation in each of the jurisdictions in which its ventures provide services. Local laws and regulations, and the interpretation of such laws and regulations, differ significantly among the jurisdictions in which the Company and its ventures operate. There can be no assurance that future regulatory, judicial and legislative changes will not have a material adverse effect on the Company, that regulators or third parties will not raise material issues with regard to the Company's or its ventures' compliance or noncompliance with applicable regulations or that any changes in applicable laws or regulations will not have a material adverse effect on the Company or any of its ventures.

Many of GTS's ventures require telecommunications licenses, most of which have been granted for periods of three to ten years. The terms and conditions of these licenses may limit or otherwise affect the ventures' scope of operations. The Company has had favorable experience obtaining, maintaining and renewing licenses in the past. However, there can be no assurance that it will be able to obtain, maintain or renew licenses to provide the services it currently provides and plans to provide, that such licenses will be issued or renewed on terms or with fees that are commercially viable, or that licenses required by future ventures can be obtained by the Company or its partners. The loss of or a substantial limitation upon the terms of these telecommunications licenses could have a material adverse effect on the Company. See each section under "Business" entitled "Licenses and Regulatory Issues."

A substantial portion of HER's strategy is based upon the timely implementation of regulatory liberalization of the European Union ("EU") telecommunications market on January 1, 1998 under existing European Community ("EC") directives. Although EU member states have a legal obligation to liberalize their markets in accordance with their requirements, certain more detailed aspects of the EU regulatory framework to apply in the liberalized environment after January 1, 1998 still remain to be adopted. In addition, Ireland, Portugal, Spain, Luxembourg and Greece have been granted extensions from the January 1, 1998 deadline. There can be no assurance that each EU member state will proceed with the expected liberalization on schedule, or at all, or that the trend toward liberalization will not be stopped or reversed in any of the countries. Accordingly, HER faces the risk that it will establish the HER network and make capital expenditures in a given country in anticipation of regulatory liberalization which does not subsequently occur.

In order to give effect to EC directives in each member state, national governments must pass legislation liberalizing their respective markets. This applies not only to the liberalization requirements set out in existing EC directives, but also to requirements set out in directives which have yet to be adopted. The implementation of EC directives in the telecommunications sector has been inconsistent or ambiguous in some EU member states. Such implementation could limit, constrain or otherwise adversely affect HER's ability to provide certain services. Furthermore, national governments may not necessarily pass legislation implementing an EC directive in the form required, or at all, or may pass such legislation only after a significant delay. Even if a national legislature enacts appropriate regulation within the time frame established by the EU, there may be significant resistance to the implementation of such legislation from PTOs, regulators, trade unions and other sources. Further, HER's provision of services in Europe may be materially adversely affected if any EU member state imposes greater restrictions on non-EU international services than on international services within the EU. These and other potential obstacles to liberalization could have a material adverse effect on HER's operations by preventing HER from establishing its network as currently intended, as well as a material adverse effect on the Company.

22

COMPETITION

GTS faces significant competition in all of its existing telecommunications businesses and for the types of acquisition and development opportunities it seeks in both emerging and Western European markets. GTS's competition in these markets includes national PTOs, multinational telecommunications carriers, other telecommunications developers and certain niche telecommunications providers. In addition, certain of the Company's joint venture partners, including Rostelecom and the regional telephone companies in Russia, certain of HER's rail-based shareholders and other entities in the emerging markets in which the Company operates, are also competitors of the Company. As a result of the recent combination under Svyazinvest of the government's majority interest in Rostelecom and 85 of the regional telephone companies, the Company may in the future be subject to more coordinated competition from its partners in the Russian telecommunications market. Although the Company believes it has a favorable and cooperative relationship with its joint venture partners, there can be no assurance that these partners will continue to cooperate with the Company in the future or that they will not increase competitive pressures on the Company. Any measures taken by the partners that reduce the level of cooperation with the Company could jeopardize the Company's ability to participate in the management and operation of its joint ventures and could have a material adverse effect on the Company.

WorldCom, Inc. ("WorldCom") recently announced the construction of a pan-European fiber network, the first phase of which is expected to connect London, Amsterdam, Brussels, Frankfurt and Paris by early 1998. Although the Company believes that the proposed WorldCom pan-European network is primarily intended to carry WorldCom traffic, WorldCom has stated that any excess capacity on such network will be used to provide a competitive "carriers' carrier" service.

HER also competes with respect to its "point-to-point" transborder service offering against circuits currently provided by PTOs through International Private Leased Circuits. In addition, the liberalization of the European telecommunications market is likely to attract additional entrants to both the "point-to-point" and other telecommunications markets. There can be no assurance that HER will compete effectively against its current or future competitors.

Many of the Company's competitors have technical, financial, marketing and other resources substantially greater than those of GTS. There can be no assurance that the Company will be able to overcome successfully the competitive pressures to which it is subject, both in the markets in which it currently operates and in markets into which it might expand. See each section under "Business" entitled "Competition." In addition, many of the Company's current and potential competitors are not subject to, or constrained by the prohibitions of, the FCPA, including the prohibition against making payments to government officials in order to obtain commercial benefits. The Company is subject to and seeks to comply with the limitations and prohibitions of such law, and accordingly may be subject to competitive disadvantages to the extent that its competitors are able to secure business, licenses or other preferential treatment through the making of such payments. Accordingly, there can be no assurances that the Company will be able to compete effectively against companies free from such limitations in the emerging markets where such commercial practices are commonplace. See "-- Adequacy of Management, Legal and Financial Controls in Emerging Markets."

CONTROL BY CERTAIN STOCKHOLDERS

Certain persons control substantial portions of the Company's voting stock. After giving effect to the Stock Offerings, Soros Foundation-Hungary and certain of its affiliates (collectively the "Soros Foundations"), Alan B. Slifka and certain of his affiliates, and affiliates of Capital Research International are expected to beneficially own, or have rights to acquire, approximately 20.4%, 10.8% and 10.1%, respectively, of the Common Stock on a fully diluted basis. See "Principal Stockholders." In addition, three persons affiliated with the Soros Foundations currently serve on the Company's Board of Directors (the "Board of Directors"). Consequently, these entities are in a position to exercise control over the outcome of matters submitted for stockholder actions, including the election of members to the Board of Directors, and are able to influence the management and affairs of the Company. Additionally, affiliates of the Soros Foundations and of Capital International, Inc. have purchased debt securities of the Company that include covenants that restrict the

23

operating and financing activities of the Company. In certain situations, the interests of holders of the Company's equity securities may diverge from the interests of the holders of the Company's debt securities, and holders of both equity and debt securities of the Company may be in a position to require GTS to act in a way that is not consistent with the general interests of the holders of the Common Stock. See "-- Substantial Additional Capital Requirements," "Management," "Principal Stockholders" and "Certain Related Party Transactions."

CURRENCY AND EXCHANGE RISKS

All of GTS's operations are conducted outside the United States. A substantial portion of the Company's anticipated revenues (as well as the majority of its operating expenses) will be in foreign currency. As a result, the Company will be subject to significant foreign exchange risks. In particular, GTS's ventures in countries whose currencies are considered "soft currencies" subject the Company to the risk that it will accumulate currencies which may not be readily convertible into hard currency and which may be subject to significant limitations on repatriation. The Company does not enter into hedging transactions to limit its foreign currency risk exposure, although the Company may implement such practices in the future. There can be no assurance that GTS's operations will not be adversely affected by such factors. In addition, these factors may limit the ability of the Company to reinvest earnings from ventures in one country to fund the capital requirements of ventures in other countries.

In Russia, where the Company derives most of its revenue, the ruble has generally experienced a steady depreciation relative to the U.S. Dollar over the past three years, although there has been some instability in the ruble exchange rate over this period of time. The Company's tariffs are denominated in U.S. Dollars but charges are invoiced and collected in rubles, while the Company's major capital expenditures are generally denominated and payable in various foreign currencies. To the extent such major capital expenditures involve importation of equipment and the like, current law permits the Company to convert its ruble revenues into foreign currency to make such payments. The ruble is generally not convertible outside Russia. A market exists within Russia for the conversion of rubles into other currencies, but it is limited in size and is subject to rules limiting the purposes for which conversion and payment may be effected. The limited availability of other currencies may tend to inflate their values relative to the ruble and there can be no assurance that such a market will continue to exist indefinitely. Moreover, the banking system in Russia is not yet as developed as its Western counterparts and considerable delays may occur in the transfer of funds within, and the remittance of funds out of, Russia. Any delay in converting rubles into a foreign currency in order to make a payment or delay in the transfer of such foreign currency could have a material adverse effect on the Company.

EXCHANGE CONTROLS AND REPATRIATION RISKS RELATING TO RUSSIAN SECURITIES

Russia has adopted currency and capital transfer regulations designed to prevent the flight of capital from its borders. These regulations require certain licenses for the movement of capital, which includes the incurrence and repayment of indebtedness and the payment of capital contributions in foreign exchange to Russian entities. The Company is resolving licensing issues with respect to certain intercompany loans and capital contributions with the applicable government agencies and believes that any licensing irregularities that may arise will not have a material adverse effect on its financial condition or results of operations. There can be no assurance, however, that Russian government authorities will not take an unexpected adverse position which could materially affect the Company's business.

No assurance can be given that Russian foreign investment and currency legislation will continue to permit repatriation of the proceeds from investments. Furthermore, no assurance can be given that further restrictions will not be imposed on the conversion of ruble earnings into foreign currency for purposes of making dividend payments or on the repatriation of profits. If any such further restrictions were imposed, they would have a material adverse effect on the Company's interests in Russia.

TRANSACTIONS WITH AFFILIATES

The Company has entered into financing agreements with certain of its affiliates. It is the Company's view that each such transaction has been on terms no less favorable to the Company than other similar transactions available to the Company with unaffiliated parties, if available at all. Generally, such transactions

24

have been the Company's only recourse to meet financing needs and/or business goals. Despite the foregoing, prospective purchasers may wish to consider the circumstances in which such transactions were made, the terms of such transactions and the Company's possible alternative courses of action. The Company may enter into transactions in the future with affiliates in order to meet its financing needs and/or business goals. See "Certain Related Party Transactions" and "Description of Certain Indebtedness."

DEPENDENCE ON KEY PERSONNEL

The Company believes that its growth and future success will depend in large part upon the efforts of a small number of key executive officers, as well as on its ability to attract and retain highly skilled and qualified personnel to work in the emerging markets in which it operates. Henry Radzikowski, who served as Chief Executive Officer -- CIS and Eastern Europe Operations from February 1994 until January 1997 and who has extensive experience in the telecommunications industry in Russia, resigned in 1997. Stewart Reich became Senior Vice President-Russia effective September 1, 1997. The Company has also replaced or reassigned executive officers and senior personnel. The competition for qualified personnel in the telecommunications industry is intense, particularly in emerging markets where the Company operates and, accordingly, there can be no assurance that the Company will be able to hire and retain qualified personnel. Although the Company believes it has maintained a strong management team, despite the change of personnel in Russia and the CIS, there can be no assurance as to what effect such personnel changes will have on the Company's operations in Russia and the CIS.

DEPENDENCE ON EFFECTIVE INFORMATION SYSTEMS

To complete its billing, the Company must record and process massive amounts of data quickly and accurately. While the Company believes its ventures' management information systems are currently adequate, certain of such systems will have to grow as the ventures' businesses expand. The Company believes that the successful expansion of its information systems and administrative support will be important to its continued growth, its ability to monitor and control costs, to bill customers accurately and in a timely fashion and to achieve operating efficiencies. There can be no assurance that the Company will not encounter delays or cost-overruns or suffer adverse consequences in implementing these systems. Any such delay or other malfunction of the Company's management information systems could have a material adverse effect on the Company's business, financial condition and results of operations.

TAXES; AVAILABILITY OF NET OPERATING LOSS CARRY FORWARDS

The tax rules and regimes prevailing in certain emerging market countries in which the Company operates or plans to operate are, in many cases, new and rapidly changing. Repatriation of profits may result in additional taxes. In addition, other forms of taxation, including VAT, excise taxes and import duties, change at an unpredictable pace and may have an adverse effect on the Company's operations.

Availability of tax holidays and provisions of tax treaties with the United States are subject to changes which may affect GTS's utilization of certain tax benefits in the countries in which it operates as well as in the United States. Certain ventures in the CIS and Hungary are operating under tax holidays granted by local governments. Tax holidays are for periods ranging from up to five to several years after achieving profitability under local tax regulations. In addition to these holidays, certain of the Company's foreign ventures have foreign tax loss carryforwards in excess of $25.0 million.

As of December 31, 1996, the Company had net operating loss carryforwards for U.S. federal income tax purposes of approximately $60.9 million expiring in fiscal years 2003 through 2011. Because of the "change in ownership" provisions of the Tax Reform Act of 1986, the utilization of the Company's net operating loss carryforwards will be subject to an annual limitation as a result of the consummation of the Offerings.

The Company's financial statements do not reflect any provision for benefits that might be associated with the U.S. and non-U.S. loss carryforwards. There can be no assurance that such loss carryforwards will be allowed, in part or full, by local tax authorities against future income.

25

TECHNOLOGY

The telecommunications industry is subject to rapid and significant changes in technology and such technological advances may reduce the relative effectiveness of existing technology and equipment. The Company obtains telecommunications equipment from a number of vendors, upon whom it is dependent for the adaptation of such equipment to meet varying local telecommunications standards. The cost of implementation of emerging and future technologies could be significant. There can be no assurance that the Company will maintain competitive services or that the Company will obtain appropriate new technology on a timely basis or on satisfactory terms. Any failure by the Company to maintain competitive services or obtain new technologies could have a material adverse effect on the Company's business, financial condition and results of operations.

Development and operation of the HER network are also subject to certain technological risks. The network has been designed to utilize SDH technology. While SDH represents an advanced, new transmission technology, HER's ability to upgrade technology from this platform may be important in establishing and/or maintaining a cost advantage over competitive carriers. There can be no assurance that the HER network will achieve the technical specifications for which it was designed or that HER will be able to upgrade the network as technological improvements in telecommunications equipment are introduced. Failure to achieve current specifications for, or future upgrades of, the network may materially and adversely affect the viability of the HER network and could have a material adverse effect on the business and prospects of GTS.

DIFFICULTY IN OBTAINING RELIABLE MARKET INFORMATION

The Company operates in markets in which it is difficult to obtain reliable market information. The Company's business planning has been based on certain assumptions concerning subscriber base, usage levels, pricing and operating expenses based on the Company's experience and the Company's own investigation of market conditions in the emerging market countries in which it operates. No assurances can be given as to the accuracy of such assumptions, and such assumptions may not be indicative of the actual performance of the Company's operations.

ENFORCEABILITY OF JUDGMENTS

Substantially all of the assets of the Company (including all of the assets of the Company's operating ventures) are located outside the United States. As a result, it will be necessary for investors to comply with foreign laws in order to enforce judgments obtained in a United States court (including those with respect to federal securities law claims) against the assets of the operating ventures, including foreclosure upon such assets, and there can be no assurance that any U.S. judgments would be enforced under any such foreign laws.

NO PRIOR PUBLIC MARKET

The Company does not intend to apply for a listing of the Notes on any national securities exchange or for quotation of the Notes through the Nasdaq National Market in the United States. The Company has been advised by the Underwriters that, following completion of the initial offering of the Notes, the Underwriters intend to make a market in the Notes, although they are under no obligation to do so and may discontinue any market-making activities at any time without notice. No assurances can be given as to the liquidity of the trading market for the Notes or that an active public market for the Notes will develop. If an active public market does not develop, the market price and liquidity of the Notes may be adversely affected.

26

USE OF PROCEEDS

The aggregate net proceeds of the Notes Offering are estimated to be approximately $96.0 million after deducting estimated expenses of the Notes Offering payable by the Company. Concurrently with the sale of the Notes, the Company intends to complete the Stock Offerings, the net proceeds of which is expected to be approximately $186.8 million after deducting estimated expenses of the Stock Offerings payable by the Company.

The Company primarily intends to use the net proceeds from the Offerings to provide working capital for existing telecommunications ventures, particularly in Russia and the CIS, to expand the Company's operations, and for general corporate purposes. The Company also intends to use a portion of the net proceeds to repay loans of $70 million (plus accrued interest) from shareholders which bear interest at 10% per annum and mature on January 19, 2001 and February 2, 2001. Also, as part of its business strategy, the Company regularly evaluates potential acquisitions and joint ventures, including the acquisition of minority interests in existing joint ventures. The Company has no definitive agreement with respect to any material acquisition or joint venture, although from time to time it has discussions with other companies and assesses opportunities on an on-going basis. A portion of the net proceeds from the Offerings may be used to fund such acquisitions. Approximately $20.0 million of the net proceeds of the Notes Offering will be placed in the Escrow Account. Pending any use of its net proceeds from the Offerings in the manner described above, the Company intends to invest the proceeds in short-term investment grade obligations, bank deposits or similar instruments.

27

(1) As a result of the Company's increase in ownership interest and amendment to the HER Shareholders Agreement that was completed on July 16, 1997, the Company accounts for its ownership interest in HER under the consolidation method of accounting. Prior to this date, the Company accounted for HER under the equity method of accounting.

(2) Because of the Company's historic losses, the Company has experienced a deficiency of earnings available to cover fixed charges throughout its existence. The deficiency of earnings available to cover fixed charges has been computed by adding loss from continuing operations before income taxes minus undistributed earnings of associated companies and fixed charges. Fixed charges consist of interest on all indebtedness and amortization of discount on all indebtedness.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
AND RESULTS OF OPERATIONS

The following is a discussion of the financial condition and results of operations of the Company as of September 30, 1997 and 1996, December 31, 1996 and 1995 and for the nine months ended September 30, 1997 and 1996 and for the years ended December 31, 1996, 1995 and 1994. The following discussion should be read in conjunction with the Company's Consolidated Financial Statements and the notes related thereto. Certain statements contained in "Management's Discussion and Analysis of Financial Condition and Results of Operations" including, without limitation, those concerning (i) projected traffic volume, (ii) future revenues and costs, (iii) changes in the Company's competitive environment and
(iv) the performance of future equity-method investments, contain forward-looking statements concerning the Company's operations, economic performance and financial condition. Because such statements involve risks and uncertainties, actual results may differ materially from those expressed or implied by such forward-looking statements.

OVERVIEW

Business. GTS is a provider of a broad range of telecommunications services to businesses, other telecommunications service providers and consumers in Russia and the CIS and Central Europe. Through HER, GTS is developing, and operating the initial segments of, a pan-European high capacity fiber optic network which is designed to interconnect a majority of the largest Western and Central European cities and to transport international voice, data and multimedia/image traffic for other carriers throughout Western and Central Europe. GTS's strategy to develop its businesses generally has been to establish joint ventures with a strong local partner or partners while maintaining a significant degree of operational control. The Company's business activities consist of the ownership and operation of (i) international long distance businesses, which operate through international gateways that provide international switching services and transmission capacity, (ii) local access networks, which provide local telephone service, (iii) cellular networks, which provide wireless telecommunications services, (iv) a domestic long distance business, (v) data networks and (vi) carriers' carrier networks, which provide high volume transmission capacity to other carriers.

The Company began to acquire interests in numerous telecommunications ventures beginning in 1994 and continued to acquire such interests throughout 1995 and 1996. Ventures with significant financial results in 1994 included Sovintel (an international long distance and domestic and local access telecommunications service provider) and GTS-Hungary (a VSAT network telecommunications service provider); ventures that incurred start-up costs associated with building out their business infrastructure in 1994 included Sovam (a data and internet telecommunications service provider) and EuroHivo (a paging telecommunications service provider). In 1995, TeleRoss (a domestic long distance telecommunications service provider) and GTS Cellular (a basic cellular telecommunications service provider) began operations and expanded into numerous regions within the CIS by the end of 1996. Telecommunications of Moscow ("TCM") (a local access telecommunications service provider) began operations in 1996. HER (a carriers' carrier telecommunications service provider) began its network build-out in 1995, began limited operations at the end of 1996 and expects to continue to develop its network during 1998 and beyond. The fact that these ventures are in various stages of development affects the discussion of comparative results below.

GTS has invested significantly in its ventures through capital contributions and loans. In addition, the Company has made a significant commitment to its businesses and ventures through the provision of management assistance and training. GTS has also incurred significant expenses in identifying, negotiating and pursuing new telecommunications opportunities. GTS and certain of its ventures are experiencing continuing losses and negative operating cash flow primarily because the businesses are in the developmental and start-up phases of operations. Management recognizes that the Company must generate additional capital resources in order to continue its operations and meet its new development initiatives. The ultimate recoverability of the Company's investments in and advances to ventures is dependent on many factors including, but not limited to, the ability of the Company to obtain sufficient financing to continue to meet its capital and operational commitments, the economies of the countries in which it does business and the ability of the Company to maintain the necessary telecommunications licenses.

31

The Company's businesses are developing rapidly. Some of the businesses operate in countries with emerging economies which have uncertain economic, political and regulatory environments. The general risks of operating businesses in the CIS and other developing countries include the possibility for rapid change in government policies including telecommunications regulations, economic conditions, the tax regime and foreign currency regulations.

ACCOUNTING METHODOLOGY

Accounting for Business Ventures. Wholly-owned subsidiaries and majority-owned ventures where the Company has unilateral operating and financial control are consolidated. Those ventures where the Company exercises significant influence, but does not exercise unilateral operating and financial control, are accounted for by the equity method. The Company has certain majority-owned ventures that are accounted for by the equity method as a result of super-majority voting conditions or other governmentally imposed uncertainties so severe that they prevent the Company from obtaining unilateral control of the venture.

Profit and Loss Accounting. The Company recognizes profits and losses in accordance with its underlying ownership percentage or allocation percentage as specified in the agreements with its partners; however, the Company recognizes 100% of the losses in ventures where the Company bears all of the financial risk (which includes all of the Company's significant ventures except for Sovintel and, historically, HER). Accordingly, the portion of the losses that would normally be assigned to the minority interest partner ("Excess Losses") is recognized by the Company. When such ventures become profitable, the Company recognizes 100% of the profits until such time as the Excess Losses previously recognized by the Company have been recovered. As of September 30, 1997, $5.3 million and $9.7 million represents the net unrecovered Excess Losses for the Company's consolidated and equity method investments, respectively, that is expected to favorably benefit future period results from operations upon the Company's existing business ventures becoming profitable. This accounting policy was adopted prior to 1995; however, 1995 was the first year that the excess loss amount was deemed material for recognition within the Company's accounting records. For the period from January 1, 1997, through August 31, 1997, the Company recognized 100% of HER's losses due to GTS being the financing partner during this period. As a result of HER's completion of a private placement of $265.0 million of senior notes (of which $56.5 million was placed in escrow for the first two years' interest payments) in August 1997, management no longer considers itself as the financing partner.

Inter-Affiliate Transactions. Several of the Company's ventures have entered into business arrangements through which they provide integrated solutions for their customers by leveraging each others' telecommunications infrastructure. These arrangements have historically been focused primarily within a region; however, as GTS has increased its geographic coverage and telecommunication capabilities, these arrangements have expanded between regions. In accordance with generally accepted accounting principles, all significant intercompany accounts and transactions are eliminated upon consolidation.

Turnover Taxes. The Company's ventures within the CIS region incur a 4% turnover tax that is based on the revenues earned. The Company includes these taxes as a component of its operating expenses, since these taxes are incidental to the revenue cycle.

The following table summarizes the accounting methodology for the principal business ventures through which the Company conducts its business.

(1) The TeleRoss Operating Company is comprised of two wholly-owned holding companies and a 99% owned subsidiary that operates a domestic long distance network and holds the applicable operating license for TeleRoss and performs the customer invoicing and collection functions for telecommunications services. TeleRoss Operating Company is accounted for under the consolidation method of accounting because GTS has unilateral control over the operations and management decisions. TeleRoss Operating Company's operations are further discussed in "-- Results of Operations -- Consolidated Ventures." A significant portion of TeleRoss Operating Company's costs of revenue consists of settlement fees paid to the TeleRoss Ventures, with such fees being recorded as revenue by the TeleRoss Ventures. In 1996 and for the nine months ended September 30, 1997, all of the TeleRoss Ventures' revenue was derived from such fees. Any decline in the business or operations of the TeleRoss Ventures would have a material adverse effect on the results of TeleRoss Operating Company.

(2) TeleRoss Ventures is comprised of thirteen joint ventures that are 50% beneficially owned by GTS, which originate traffic and provide local termination of calls through agency arrangements with TeleRoss Operating Company. GTS does not exercise unilateral control over the TeleRoss Ventures and therefore, they are appropriately accounted for under the equity method of accounting. TeleRoss Ventures' operations are further discussed in "-- Results of Operations -- Non-Consolidated Ventures."

(3) GTS has reached an agreement in principle to purchase its minority partner's 33% interest in Sovam and expects to consummate the transaction in January 1998, thereby making Sovam a wholly owned subsidiary of GTS.

(4) GTS conducts its cellular operations through (i) Vostok Mobile, a wholly owned GTS venture which owns between 50% and 70% of a series of 11 cellular joint ventures in various regions in Russia, (ii) PrimTelefone, a 50% owned venture in Vladivostok, Russia and (iii) Bancomsvyaz, an approximately 25% beneficially-owned venture in Kiev, Ukraine.

(5) As of July 16, 1997, HER is accounted for by the consolidation as opposed to the equity method of accounting.

RESULTS OF OPERATIONS -- CONSOLIDATED VENTURES

Management's discussion included within "-- Results of Operations -- Consolidated Ventures" reflects the following significant operating ventures: TeleRoss Operating Company, GTS-Hungary, CzechNet and CzechCom (collectively the "Czech Companies") and HER (for fiscal 1997). See "Results of Operations -- Non-Consolidated Ventures (Equity Investees)" for a discussion of the operating results of Sovintel, TCM, Sovam, TeleRoss Ventures, GTS Cellular, HER (prior to fiscal 1997), GTS-Monaco Access, EuroHivo and the Asia business ventures.

Nine Months Ended September 30, 1997 compared to Nine Months Ended September 30, 1996

Revenue. The Company's consolidated revenue for the nine months ended September 30, 1997 increased by $15.6 million to $30.2 million, an increase of over 100% from the comparable period in 1996. TeleRoss Operating Company's growth accounted for approximately 54.3% of the Company's total growth over the nine months ended September 30, 1997.

The CIS region's consolidated revenue was $19.0 million for the nine months ended September 30, 1997, of which TeleRoss' revenue comprised 86.3%. TeleRoss Operating Company's revenue increased by $10.3 million to $16.4 million for the nine months ended September 30, 1997, from the comparable period in 1996. Service revenue represented approximately 69.5% of the total TeleRoss Operating Company revenue for the nine months period ended September 30, 1997. The remaining revenue generated by TeleRoss Operating Company was primarily related to equipment sales and installation revenue of $2.9 million and $1.8 million for the nine months ended September 30, 1997 and 1996, respectively.

Within the Central Europe region, GTS-Hungary and the Czech Companies accounted for 100% of the $9.5 million in revenue earned for the nine months ended September 30, 1997. GTS-Hungary's revenue increased by $1.4 million to $5.9 million for the nine months ended September 30, 1997, from the comparable period in 1996, largely due to a 25.0% increase in the number of VSATs installed since September 1996. Revenue of the Czech Companies, which provide a range of international telephone, private data and internet access services, increased by $2.4 million to $3.6 million, for the nine months ended September 30, 1997, from the comparable period in 1996, primarily due to increased voice and internet traffic and lease line services.

All of Western Europe's consolidated revenue of $2.3 million for the nine months ended September 30, 1997 was derived from HER's initial Amsterdam to Brussels route.

Gross Margin. GTS's consolidated gross margin was $1.9 million and $1.8 million, or 6.3% and 12.0% of total revenue, for the nine months ended September 30, 1997 and 1996, respectively. The decrease in consolidated gross margin as a percentage of revenue was attributable to the consolidation of HER in fiscal 1997.

TeleRoss Operating Company had a gross margin of $1.0 million and $(1.0) million for the nine months ended September 30, 1997 and 1996, respectively. GTS-Hungary had gross margins of $2.7 million and $1.9 million for the nine months ended September 30, 1997 and 1996, respectively (representing 45.8% and 42.2% of GTS-Hungary's revenue during these periods). The remaining consolidated gross margin of $(1.8) million and $0.9 million for the nine months ended September 30, 1997 and 1996, respectively, was primarily attributable to HER, which generated a negative gross margin of $(3.2) million for the nine months ended September 30, 1997, and to the Czech Companies, which generated gross margin of $0.9 million and $0.2 million for the nine months ended September 30, 1997 and 1996, respectively.

Operating Expenses. Consolidated operating costs were $52.1 million and $35.7 million for the nine months ended September 30, 1997 and 1996, respectively. The increase in operating costs reflected the growth in expenditures associated with building business infrastructure, the inclusion of HER's operating expenses and increasing corporate staff.

Equity in (Losses)/Earnings of Ventures. GTS recognized losses from its investments in non-consolidated ventures of $18.2 million and $7.0 million for the nine months ended September 30, 1997 and 1996, respectively. Included in these losses were $10.4 million and $5.1 million for the nine months ended

34

September 30, 1997 and 1996, respectively, that related to GTS's ownership share of the losses incurred. The increase in the Company's losses from its ventures was primarily the result of write-downs of investments and assets of approximately $17.4 million and $2.4 million in the Asia and Central Europe regions, respectively, for the nine months ended September 30, 1997. The Company would have recognized earnings from its investments in non-consolidated ventures of $1.6 million for the nine months ended September 30, 1997, had the Company not recognized the write-downs of investments and assets of approximately $17.4 million and $2.4 million, respectively. The Asia region write-downs were the result of management's periodic reassessment of the recoverability of its long-lived assets, and accordingly, specific assets are now reflected at their fair value as determined by their expected recovery as of September 30, 1997. Their fair value was based on the estimated future cash flows to be generated by the assets, discounted at a market rate of interest. The write-down of Central Europe's investment in EuroHivo was a result of the Company's decision in the third quarter to recognize the contingent liabilities associated with the expected liquidation and discontinuation of EuroHivo's operations as of September 30, 1997. In addition, the Company's results were negatively affected by the recognition of Excess Losses of $5.5 million and $1.9 million for the nine months ended September 30, 1997 and 1996, respectively. As of September 30, 1997, $9.7 million represents the net unrecovered Excess Losses for the Company's equity method investments, respectively, that is expected to favorably benefit future period results from operations upon the Company's existing equity method business ventures becoming profitable. CIS' ventures, primarily Sovintel and TCM (with combined earnings to the Company of $11.6 million and $8.3 million for the nine months ended September 30, 1997 and 1996, respectively), generated earnings for the Company of approximately $8.2 million and $5.0 million for the nine months ended September 30, 1997 and 1996, respectively, which partially offset losses generated by other ventures. See "-- Results of Operations -- Non-Consolidated Ventures (Equity Investees)."

Interest, Net. GTS incurred interest expenses of $21.1 million and $7.3 million for the nine months ended September 30, 1997, and 1996, respectively. Interest expense is comprised of interest accrued from debt maturing within one year, long-term debt obligations, amortization of debt discount on the long-term debt obligations and various other debt instruments. The increase in interest expense was primarily related to the issuance of $144.8 million in Convertible Bonds in July 1997 and $265.0 million in senior notes raised in August 1997 by HER. See "-- Liquidity and Capital Resources."

GTS earned interest income of $5.3 million and $1.5 million for the nine months ended September 30, 1997 and 1996, respectively, primarily as a result of investing the proceeds from equity and debt offerings in various highly liquid investments.

Provision for Income Taxes. The company's consolidated tax provision was $1.8 million and $1.0 million for the nine months ended September 30, 1997 and 1996, respectively. The Company's income tax rates are significantly affected by foreign taxes and the utilization of net operating losses. In addition, the Company operates worldwide in numerous tax jurisdictions. As a result, losses incurred in one jurisdiction may not be available to offset income in another.

Year Ended December 31, 1996 compared to Year Ended December 31, 1995 and compared to Year Ended December 31, 1994

Revenue. The Company's consolidated revenue was $24.1 million, $8.4 million and $2.5 million for the years ended December 31, 1996, 1995 and 1994, respectively. The growth in revenue was attributable to the commencement in 1995 of commercial operations by TeleRoss Operating Company, as well as the continued expansion of services and customer base in Central Europe.

TeleRoss Operating Company generated revenue of $9.2 million and $3.8 million, representing 38.3% and 44.9% of the Company's consolidated revenue for the years ended December 31, 1996 and 1995, respectively. Service revenue represented 64.1% and 21.1% of TeleRoss Operating Company's revenue for the years ended December 31, 1996 and 1995, respectively, with the balance of its revenue in such periods principally represented by equipment sales. The growth in revenue was a result of increased traffic volume generated by the TeleRoss Ventures as they expanded to seven new cities during the year ended December 31, 1996, added customers in existing cities and installed several VSATs at customer locations outside of cities in which they have a presence.

35

GTS-Hungary and the Czech Companies accounted for $6.9 million and $2.3 million of the Company's consolidated revenue in 1996, respectively, compared to $4.2 million and $0.3 million in 1995, respectively, and $1.3 million and none in 1994, respectively. The growth in revenue of GTS-Hungary from 1994 to 1996 was due to the expansion of its customer base and the introduction of microwave technology services. The Hungary state lottery accounted for 55.3%, 65.0% and 67.2% of GTS-Hungary's revenue in 1996, 1995 and 1994, respectively. The growth in revenue of the Czech Companies was generated through increases in voice traffic carried from sixteen buildings at December 31, 1996 as compared to eight buildings at December 31, 1995.

Gross Margin. GTS's consolidated gross margin was $5.2 million, or 21.6% of revenue, for the year ended December 31, 1996 and $0.02 million, or 0.0% of revenue, for the years ended December 31, 1995 and 1994.

TeleRoss Operating Company incurred a negative gross margin of $1.0 million for both the years ended December 31, 1996 and 1995 which was the result of the high fixed cost component of its network hub in Moscow. GTS-Hungary had a gross margin of $3.0 million, $1.7 million and $(0.3) million, representing 43.4%, 40.5% and (23.1)% of GTS-Hungary's revenue for the years ended December 31, 1996, 1995 and 1994, respectively. The favorable gross margin trend reflected the increased utilization of GTS-Hungary's 1,000 VSAT capacity hub located in Budapest. The remaining gross margin of $3.2 million for the year ended December 31, 1996 was attributable to the higher margin sales of equipment and consulting services.

Operating Expenses. Consolidated operating costs were $52.9 million, $41.0 million and $12.9 million for the years ended December 31, 1996, 1995 and 1994, respectively. The increase in operating costs reflected the growth in expenditures associated with building business infrastructure for primarily the TeleRoss Operating Company and GTS-Hungary and increasing corporate staff.

Equity in (Losses)/Earnings of Ventures. GTS recognized losses from its investments in non-consolidated ventures of $10.2 million, $7.9 million and $0.1 million for the years ended December 31, 1996, 1995 and 1994, respectively. Included in these losses were $5.7 million, $5.2 million and $0.1 million for the years ended December 31, 1996, 1995 and 1994, respectively, that related to GTS's ownership share of the losses. In addition, the Company's results were negatively affected due to the recognition of Excess Losses of $4.5 million and $2.7 million for the years ended December 31, 1996 and 1995, respectively. See "--Overview." The Company would have recognized additional losses of $8.2 million and $3.3 million for the years ended December 31, 1996 and 1995, respectively, had the Company been considered the financing partner of HER during those time periods. The Company's losses from its ventures were primarily the result of most of its ventures being in the early stages of operations. Sovintel and TCM, however, generated combined earnings of $11.8 million and $3.8 million for the years ended December 31, 1996 and 1995, respectively, which partially offset losses generated by other ventures.

Other Non-Operating Income. Favorably affecting the 1995 results was the non-recurring $10.3 million gain the Company recognized as a result of its cash settlement of certain claims with a third party in 1995.

Interest, Net. GTS incurred interest expense of $11.1 million, $0.7 million and $0.1 million for the years ended December 31, 1996, 1995 and 1994, respectively. The increase in interest expense was due to the $60.0 million increase in debt during 1996. See "--Liquidity and Capital Resources."

GTS earned interest income of $3.6 million, $2.2 million and $1.2 million for the years ended December 31, 1996, 1995 and 1994, respectively, primarily as a result of investing the proceeds from private placements of common stock in various highly liquid investments.

Provision for Income Taxes. The Company's consolidated tax provision was $1.4 million and $2.6 million for the years ended December 31, 1996 and 1995, respectively. These rates were significantly affected by foreign taxes and the utilization of net operating losses. In addition, the Company operates world-wide in numerous tax jurisdictions. As a result, losses incurred in one jurisdiction may not be available to offset income in another. The Company had no income tax expense for the year ended December 31, 1994.

RESULTS OF OPERATIONS -- NON-CONSOLIDATED VENTURES (EQUITY INVESTEES)

Nine Months Ended September 30, 1997 compared to Nine Months Ended September 30, 1996

RUSSIA -- CIS

Sovintel. Sovintel's revenue increased by 58.9% to $82.0 million for the nine months ended September 30, 1997, from $51.6 million for the comparable period in 1996. The increase in revenue was primarily the result of telecommunications services revenue, which increased to $61.5 million for the nine months ended September 30, 1997, from $34.9 million for the nine months ended September 30, 1996, due to the Moscow customer base growth and traffic from other GTS ventures that generated increased volume of outgoing international and domestic minutes carried by Sovintel. Incoming international revenue grew significantly by $6.3 million to $9.9 million for the nine months ended September 30, 1997, from the comparable period in 1996. Included in Sovintel's 1997 traffic revenue was $8.7 million for the nine months ended September 30, 1997, that was related to customers using phone numbers provided by TCM. This revenue was derived primarily from international/long distance traffic and local traffic. Sovintel and TCM have an arrangement whereby Sovintel reimburses TCM 50% of installation charges, monthly fees and local traffic revenues and approximately 33% of the international/long distance billings from TCM-supplied phone numbers.

Sovintel's non-traffic related revenue increased to $20.5 million for the nine months ended September 30, 1997, from $16.7 million for the comparable period in 1996. In March 1997, Sovintel's historically largest customer for port sales revenue, MTS, received its own numbering plan. Accordingly, management expects revenue from port sales to continue to decline.

Sovintel's gross margin percentage decreased to 37.8% for the nine months ended September 30, 1997, as compared to 40.7% for the comparable period in 1996, in part due to a general price decrease implemented in April 1997.

Operating expenses were $12.4 million and $7.3 million, or 15.1% and 14.1% of total revenue, for the nine months ended September 30, 1997 and 1996, respectively. The increase in operating expenses for the nine months ended September 30, 1997 was related to an increase in turnover taxes associated with revenues, and also increased personnel, advertising and sales force costs required to support Sovintel's growth.

Income tax expense was $4.7 million and $3.9 million for the nine months ended September 30, 1997 and 1996, respectively.

TCM. TCM's revenue grew 64.9% to $20.7 million for the nine months ended September 30, 1997, from the comparable period in 1996. TCM's gross margin was $16.0 million and $10.3 million, or 77.3% and 81.7% of total revenue, for the nine months ended September 30, 1997 and 1996, respectively. The decrease in gross margin as a percentage of revenue was attributable to higher infrastructure and settlement costs. Operating expenses were $2.0 million and $1.2 million, or 9.7% and 9.5% of total revenue, for the nine months ended September 30, 1997 and 1996, respectively.

Sovam. Sovam's revenue increased by 61.3% to $12.9 million for the nine months ended September 30, 1997, from the comparable period in 1996. Sovam's revenue was derived primarily from data services, network capabilities and application revenues. The increase in revenue is primarily attributable to the expansion of Sovam's network throughout Russia and the CIS and the improvement in the quality of Internet services due to increased international bandwidth.

Sovam's gross margin was $5.0 million, or 39.5% of total revenue, for the nine months ended September 30, 1997, up from $2.1 million, or 26.3%, for the nine months ended September 30, 1996. Operating expenses were $4.6 million and $4.2 million, or 35.7% and 52.5% of total revenue, for the nine months ended September 30, 1997 and 1996, respectively.

TeleRoss Ventures. Revenue for the TeleRoss Ventures for the nine months ended September 30, 1997 and 1996 was $5.1 million and $1.3 million, respectively. The increase in revenues reflected growth in settlement fees charged to the TeleRoss Operating Company. The settlement fees are based on minutes of use by regional customers in the core switched voice services, as well as installation work and equipment sales.

37

Gross margin was $3.7 million and $0.8 million, or 72.6% and 66.6% of total revenue, for the nine months ended September 30, 1997 and 1996, respectively. Operating expenses of $2.5 million and $1.5 million were incurred for the nine months ended September 30, 1997 and 1996, respectively.

GTS Cellular. The Company operates three cellular networks through differing ownership structures; Vostok Mobile, Prim Telefone and Bancomsvyaz.

Revenue for Vostok Mobile increased by 41.5% from $10.6 million to $15.0 million for the nine months ended September 30, 1997, from the comparable period in 1996, as a result of increased subscribership to approximately 11,000 at September 30, 1997. Vostok Mobile's gross margin was $7.6 million and $5.3 million, or 50.7% and 50.0% of total revenue, for the nine months ended September 30, 1997 and 1996, respectively. Operating expenses were $4.8 million and $5.4 million for the nine months ended September 30, 1997 and 1996, respectively. The higher operating costs in 1996 was attributed to development and start-up expenses related to new business ventures.

Revenue for PrimTelefone increased by 43.3% to $8.2 million for the nine months ended September 30, 1997, from the comparable period in 1996, due to an increase in subscribership to approximately 4,600 as of September 30, 1997.

PrimTelefone's gross margin was $4.7 million and $3.0 million, or 57.3% and 52.6% of total revenue, for the nine months ended September 30, 1997 and 1996, respectively. Operating expenses were $2.7 million and $1.5 million, or 32.9% and 26.3% of total revenue, for the nine months ended September 30, 1997 and 1996, respectively.

Revenues for Bancomsvyaz was $4.0 million for the nine months ended September 30, 1997, with a gross margin of $1.5 million and operating expenses of $3.4 million for the nine months ended September 30, 1997, respectively.

WESTERN EUROPE

GTS-Monaco Access. In 1997, GTS-Monaco Access revenue increased significantly to $7.9 million for the nine months ended September 30, 1997, from $2.2 million for the same period in 1996. The increase was the result of a substantially larger traffic base and number of countries covered under the network. Gross margin for the nine months ended September 30, 1997 and 1996 was $0.4 million and $(0.3) million, respectively.

CENTRAL EUROPE

Eurohivo. Eurohivo's operating results were minimal for the nine months ended September 30, 1997 and 1996. In September 1997, the Company recorded a $2.4 million charge in the third quarter to recognize the contingent liabilities associated with the planned liquidation and discontinuance of Eurohivo's operations. See Footnote 2 in the Company's condensed consolidated financial statements for additional disclosures related to Eurohivo.

ASIA

Most of the Company's ventures within the Asia region were in the start-up phase and had not commenced operations in 1996. The non-consolidated ventures in the Asia region had no revenue for the nine months ended September 30, 1997, and had minimal revenue of $0.5 million for the nine months ended September 30, 1996. See Footnote 2 in the Company's condensed consolidated financial statements for additional disclosures related to the Company's Asia operations.

Year Ended December 31, 1996 compared to Year Ended December 31, 1995 and compared to Year Ended December 31, 1994

RUSSIA -- CIS

Sovintel. Sovintel's revenue for the years ended December 31, 1996, 1995 and 1994 was $75.0 million, $44.3 million, and $20.7 million, respectively. Sovintel's revenue was derived from telecommunications

38

services, including international, domestic and local traffic, and other non-traffic related revenue associated with port and equipment sales, leased line installation and maintenance. Telecommunications services traffic revenue was $50.8 million, $26.8 million and $19.5 million, representing 67.7%, 60.5% and 94.2% of Sovintel's total revenue, for the years ended December 31, 1996, 1995 and 1994, respectively.

Revenue from outgoing international, domestic long distance and Moscow local traffic was $44.0 million, $24.6 million and $18.0 million for the years ended December 31, 1996, 1995 and 1994, respectively. This growth was due to Sovintel's increased customers in Moscow and traffic from other GTS ventures. Sovintel began providing Moscow local access services in 1995. Revenue from incoming international minutes was $6.8 million, $2.2 million and $1.5 million for the years ended December 31, 1996, 1995 and 1994, respectively. Included in Sovintel's 1996 traffic revenue was $5.0 million from customers using phone numbers provided by TCM.

Sovintel's non-traffic related revenue of $24.2 million, $17.5 million and $1.2 million for the years ended December 31, 1996, 1995 and 1994, respectively, was primarily attributable to non-recurring port sales revenues of $12.4 million and $14.4 million for the years ended December 31, 1996 and 1995, respectively. Included in 1996 non-traffic related revenue was $3.7 million from one-time installation charges related to TCM-supplied phone numbers. There were no significant port sales in 1994.

Sovintel's gross margin was $31.1 million, $18.0 million and $8.2 million, or 41.5%, 40.6% and 39.6% of revenue, for the years ended December 31, 1996, 1995 and 1994, respectively. The gross margin percentage remained relatively unchanged over the past three years as the decrease in average revenue per minute for international and intercity calls was partially offset by the decrease in average settlement cost per minute.

Operating expenses were $10.3 million, $7.1 million and $4.6 million, or 13.7%, 16.0% and 22.2% of total revenue, for the years ended December 31, 1996, 1995 and 1994, respectively. Turnover taxes and personnel related costs comprised the majority of the increase in selling, general and administrative costs. The increase in personnel related costs reflected the growth in sales and general operations of Sovintel.

Income tax expense was $5.2 million and $2.6 million for the years ended December 31, 1996 and 1995, respectively. The increase in income tax expense was attributable to Sovintel's profitable operations. According to Russian Federation tax holiday provisions, Sovintel was exempt from income taxes for a two-year period beginning with the first year of taxable income, which was in 1993.

TCM. TCM's total revenue was $16.5 million for the year ended December 31, 1996 and had minimal activities in 1995. TCM had a gross margin of $13.2 million, or 80.0% of total revenue, and operating expenses of $1.9 million, or 11.5% of total revenue, for the year ended December 31, 1996.

Sovam. Sovam's revenue was $11.7 million, $4.4 million and $3.3 million for the years ended December 31, 1996, 1995 and 1994, respectively. The increase in revenues is primarily attributable to the wider variety of service offerings, including the introduction of Russia On Line services.

Gross margin was $3.4 million, $1.5 million and $1.8 million, or 29.1%, 34.1% and 54.6% of total revenue for the years ended December 31 in 1996, 1995 and 1994, respectively. The decline in gross margin as a percentage of revenue was reflective of the higher cost of sales component in Sovam's recently introduced products. Operating expenses were $5.7 million, $3.3 million and $2.1 million, or 48.7%, 75.0% and 63.6% of total revenue, for the years ended December 31, in 1996, 1995 and 1994, respectively.

TeleRoss Ventures. Revenues for TeleRoss Ventures for the years ended December 31, 1996 and 1995 were $2.4 million and $0.1 million, respectively. Revenues resulted from settlement fees charged to TeleRoss Operating Company. The growth in total revenue was the result of steady growth in sales of core switched voice services in the five cities serviced in 1995 as well as the addition of seven new cities to the network in 1996.

Gross margin for the years ended December 31, 1996 and 1995 was $1.6 million and $0.1 million, respectively. Operating expenses of $2.3 million and $0.2 million were incurred for the years ended December 31, 1996 and 1995, respectively.

39

GTS Cellular. The Company operates three cellular networks through differing ownership structures: Vostok Mobile, PrimTelefone and Bancomsvyaz.

Revenue for Vostok Mobile was $16.5 million and $2.0 million for the years ended December 31, 1996 and 1995, respectively. Vostok Mobile's gross margin was $9.3 million and $1.1 million, or 56.4% and 55.0% of total revenue, and operating expenses were $9.2 million and $4.7 million for the year ended December 31, 1996 and 1995, respectively.

Revenue for PrimTelefone was $8.4 million and $2.2 million for the years ended December 31, 1996 and 1995, respectively. PrimTelefone's gross margin was $4.7 million and $0.6 million, or 56.0% and 27.3% of total revenue, and operating expenses were $3.7 million and $0.7 million for the years ended December 31, 1996 and 1995, respectively.

Bancomsvyaz did not have significant operations until 1997.

WESTERN EUROPE

HER. HER represents substantially all of GTS's investment in the Western Europe region. A small operational revenue stream was earned in 1996.

Operating expenses were $16.0 million, $6.7 million and $0.2 million for the years ended December 31, 1996, 1995 and 1994, respectively. The increase in selling, general and administrative expenses reflected HER's continued transition from the start-up phase to the operational phase.

GTS-Monaco Access. Limited international traffic was carried from GTS subsidiaries through GTS-Monaco Access for termination worldwide during 1995 which resulted in minimal revenues earned. Total revenue was $3.9 million and gross margin was $(0.4) million for the year ended December 31, 1996.

CENTRAL EUROPE

EuroHivo. EuroHivo's revenue was $1.0 million and $0.5 million for the years ended December 31, 1996 and 1995, respectively. Although revenue improved significantly during 1996, EuroHivo continued to show negative gross margins of $(0.2) million and $(0.5) million for the years ended December 31, 1996 and 1995, respectively. Furthermore, operating expenses decreased to $1.9 million for the year ended December 31, 1996 from $2.4 million for the year ended December 31, 1995 despite a 64.0% increase in personnel during 1996. This was primarily attributable to management's decision to grow revenue through alternative measures resulting in significant reductions to advertising expenditures in 1996.

ASIA

Most of the Company's ventures within the Asia region were in the start-up phase and had not commenced operations in 1996. The non-consolidated ventures in the Asia region had revenue of $7.0 million and $0.0 million for the years ended December 31, 1996 and 1995, respectively. The revenue in 1996 consisted principally of equipment sales. The Company believes that future revenue will be derived primarily from providing telecommunications engineering and consulting services.

LIQUIDITY AND CAPITAL RESOURCES

The telecommunications business is capital intensive. The Company generally is the primary source of funding for its ventures, both for working capital and capital expenditures. Under a typical arrangement, GTS's venture partner contributes the necessary licenses or permits under which the venture will conduct its business, office space and other equipment. GTS's contribution is generally cash and equipment, but may consist of other specific assets as required by the joint venture agreement.

The Company has raised capital through the issuance of equity securities and through various debt agreements. The issuance of equity securities has raised $36.5 million, $107.7 million, $42.1 million and $62.1 million in 1997, 1996, 1995 and 1994, respectively, net of placement fees, for a total of $248.4 million. In addition, the Company and HER received $409.8 million, $60.0 million and $23.3 million in 1997, 1996 and

40

1995, respectively, for a total of $493.1 million under various debt agreements. Included within the debt proceeds identified above, the Company received $3.5 million, $60.0 million and $10.0 million in 1997, 1996 and 1995, respectively, from lenders who are affiliated with, and are considered related parties to, the Company as a result of their (or their affiliates) ownership of the Company's Common Stock.

The Company had working capital of $353.4 million and $66.5 million as of September 30, 1997 and 1996, respectively. Approximately $190.0 million of the $353.4 million of working capital at September 30, 1997, is restricted, pursuant to the terms and conditions of the senior notes issued by HER in August 1997, for the buildout of the HER Network. The Company had an accumulated deficit of $213.8 million as of September 30, 1997, including a net loss of approximately $87.9 million and $48.5 million for the nine months ended September 30, 1997 and 1996, respectively. During 1997, the Company has incurred and expects to continue to incur substantial expenditures to fund the working capital requirements of its ventures, to provide capital equipment for certain of its ventures, and to engage in new development and acquisitions.

GTS will require substantial capital investment to execute its business plans and to fund expected operating losses. Management expects that GTS and its ventures will incur over $515.0 million of capital expenditures during the next three fiscal years, of which approximately $235.0 million will be incurred in 1998. The Company has obtained funds in 1997 through a variety of financing arrangements, including (i) the issuance in September 1997 of $39.2 million of Common Stock in a private placement of equity with a value of $15.67 per common share, (ii) the issuance in August 1997 of $265.0 million in gross proceeds (of which $56.5 million was placed into escrow to fund the first two years' interest payments) of 11.5% Senior Notes by HER that may be redeemed upon the successful completion of a complying equity offering or meeting other certain criteria, and
(iii) the issuance in July and August 1997 of $144.8 million in gross proceeds of the Convertible Bonds by GTS, that are convertible into Common Stock upon the Company's completion of a complying equity offering.

The Company believes that the net proceeds from the Offerings, together with existing cash and cash flow from operations, if any, will be sufficient to fund its expected capital needs until at least June 1999. The Company expects that it may require additional capital to execute its current business plan and to fund expected operating losses, as well as to consummate future acquisitions and exploit opportunities to expand and develop its businesses. There can be no assurances that the Company will be able to consummate additional financing on favorable terms. As a result, the Company may be subject to additional or more restrictive financial covenants, its interest obligations may increase significantly and its existing shareholders may be adversely diluted. Failure to generate sufficient funds in the future, whether from operations or by raising additional debt or equity capital, may require the Company to delay or abandon some or all of its anticipated expenditures, to sell assets, or both, either of which could have a material adverse effect on the operations of the Company.

HER

Construction of the HER fiber optic network is one of the Company's most significant business activities. The buildout of the network is expected to require approximately $290.0 million of capital expenditures during fiscal year 1998 and thereafter, with approximately $35.0 million required for initial five country network. As of September 30, 1997, approximately $27.6 million has been spent on network capital expenditures. In August 1997, HER completed the issuance of $265.0 million in gross proceeds of 11.5% Senior Notes due in August 2007. The Senior Notes are be general unsecured obligations of HER. HER currently estimates that its capital resources will be sufficient to fund operations and expected network development through December 1998, at which time it may be required to obtain additional funds. Sources of capital to fund network development after 1998 may include internally generated funds, bank debt and vendor financing. HER is currently in discussion with a number of financial institutions to obtain debt financing and to negotiate vendor financing with key suppliers of network equipment. Any failure to obtain necessary financing may require HER to delay or abandon its plans for the deploying the remainder of the network and would jeopardize the viability of HER, or may require the Company to make additional capital contributions to HER at the expense of the Company's other operations, either of which could have a material adverse effect on the

41

operations of the Company. There can be no assurance that GTS or its partners in HER would have sufficient capital to make contributions to HER, or that they would be willing to do so.

Pursuant to the Recapitalization, HER offered to GTS-Hermes, HIT Rail and the eleven individual members of the HIT Rail consortium the right to subscribe to additional common stock of the Company. GTS-Hermes and two of the members of HIT Rail exercised their rights, while HIT Rail and the nine remaining members of HIT Rail declined to participate.

As a result of the finalization of the Recapitalization, total shareholder loans of ECU 39.4 million (approximately $48.5 million) from, collectively, GTS-Hermes, HIT Rail and two of the members of HIT Rail, were converted into equity. Additionally, GTS-Hermes contributed ECU 46.0 million (approximately $51.8 million) and one of the members of HIT Rail contributed a ten-year fiber optic cable lease which was valued at ECU 1.8 million (approximately $2.0 million). The ownership of HER subsequent to the recapitalization was as follows: GTS-Hermes, 79.08%; HIT Rail, 12.63%; and the two members of HIT Rail combined, 8.29%. See "Business -- Western Europe -- HER -- HER Recapitalization."

Liquidity Analysis

The Company had cash and cash equivalents of $366.8 million and $86.5 million as of September 30, 1997 and 1996, respectively. Approximately $190.0 million of the $366.8 million of cash and cash equivalents at September 30, 1997, is restricted for the build-out of the HER network. The Company had restricted cash of $59.8 million and $3.9 million as of September 30, 1997 and 1996, respectively. Restricted cash included amounts held in escrow to pay the first two years' interest payments on the Senior Notes of HER, amounts held for equipment purchases under various debt agreements, and cash maintained in foreign financial institutions that may not be readily convertible into dollars or easily repatriated.

During the nine months ended September 30, 1997 and 1996, the Company used $38.9 million and $31.8 million, respectively, of cash for operating activities. Cash used for investing activities was $73.0 million and $48.0 million for the nine months ended September 30, 1997 and 1996, respectively. The use of cash in operations and for investing activities reflected primarily the development and buildout of existing telecommunications networks and the funding of fully operational ventures.

Substantially all of the Company's operations are in foreign countries and therefore the Company's consolidated financial results are subject to fluctuations in currency exchange rates. The Company's consolidated operations transact their business in the following significant currencies: Russian Ruble, Hungarian Forint, Belgian Franc and the European Currency Unit. For those operating companies that transact their business in currencies that are not readily convertible, the Company attempts to minimize its exposure by indexing its invoices and collections to the applicable dollar/foreign currency exchange rate to the extent its costs (including interest expense, capital expenditures and equity) are incurred in U.S. dollars. Although the Company will continue to attempt to match revenues, costs, borrowing and repayments in terms of their respective currencies, the Company may experience economic loss and a negative impact on earnings with respect to holdings solely as a result of foreign currency exchange rate fluctuations, which include foreign currency devaluations against the U.S. dollar. Furthermore, certain of the Company's operations have notes payable and notes receivable which are denominated in a currency other than their own functional currency or loans linked to the U.S. dollar. The Company may also experience economic loss and a negative impact on earnings related to these monetary assets and liabilities.

The Company is in the process of developing risk management policies that will establish guidelines for managing foreign exchange risk. The Company expects that these policies will be implemented in the first quarter of 1998, and anticipates that these policies will allow management to use financial hedging instruments to manage foreign exchange exposure. Currently, the Company is considering alternatives to hedge foreign exchange exposure resulting from the issuance of $265 million in senior notes by HER.

BUSINESS

INTRODUCTION

GTS is a provider of a broad range of telecommunications services to businesses, other telecommunications service providers and consumers in Russia, the CIS and Central Europe. Through HER, GTS is developing, and operating the initial segments of, a pan-European high capacity fiber optic network that is designed to interconnect a majority of the largest Western and Central European cities and to transport international voice, data and multimedia/image traffic for other carriers throughout Western and Central Europe. GTS's strategy to develop its businesses generally has been to establish joint ventures with a strong local partner or partners while maintaining a significant degree of operational control. The Company's business activities consist of the ownership and operation of (i) international long distance businesses, which operate through international gateways that provide international switching services and transmission capacity, (ii) local access networks, which provide local telephone service, (iii) cellular networks, which provide wireless telecommunications services, (iv) a domestic long distance business, (v) data networks and (vi) carriers' carrier networks, which provide high volume transmission capacity to other carriers.

In Russia and the CIS, GTS's objective is to become the premier alternative telecommunications operator. To attain its objective, the Company has partnered with regional telephone companies and with Rostelecom, the national long distance carrier in Russia. The Company currently operates in 24 oblasts (regions) and the city of Moscow in Russia, as well as in 11 additional cities in the CIS, and believes it is well-positioned to become the leading independent telecommunications service provider in Russia. These businesses include: (i) Sovintel, which provides Moscow, and recently St. Petersburg, with international long distance and local telephone services and access to the major domestic long distance carriers; (ii) TCM, which provides local access services in Moscow;
(iii) TeleRoss, which provides domestic long distance services in fourteen cities in Russia, including Moscow, as well as VSAT service to customers outside its primary long distance satellite network; (iv) Sovam, which provides data services, including high-speed data transmission, electronic mail, Internet access services, as well as Russia On Line, the first Russian language Internet service; and (v) GTS Cellular, which operates cellular networks in twelve regions in Russia and also in Kiev, Ukraine, with licenses covering regions with an aggregate population of approximately 25 million people at the end of 1996. Whenever practical, GTS's businesses integrate and co-market their service offerings in Russia and the CIS, utilizing TeleRoss as the domestic long distance provider, Sovintel as the international gateway, TCM and GTS Cellular for local access, and Sovam as the data communications and Internet access network for business applications and on-line services. Together, GTS's Russian and CIS ventures carried 202.5 million and 291.3 million minutes of traffic for the year ended December 31, 1996 and the nine months ended September 30, 1997, respectively, and had approximately 24,600 customers, including approximately 16,300 cellular subscribers, as of September 30, 1997. See "-- Russia and the CIS."

In Western Europe, GTS seeks to position itself as the leading independent carriers' carrier through the development of two ventures, HER and GTS-Monaco Access. HER's objective is to become the leading pan-European carriers' carrier by providing centrally managed cross-border telecommunications transmission capacity to telecommunications companies including traditional PTOs and New Entrants on an approximately 18,000 kilometer pan-European high capacity fiber optic network designed to interconnect a majority of the largest Western and Central European cities. HER is currently operating over an approximately 1,700- kilometer portion of the network linking Brussels, Antwerp, Rotterdam, Amsterdam, London and Paris. HER expects the initial five country network to be placed in operation in the second quarter of 1998. This segment of the network is expected to deliver managed transport services over approximately 2,900 kilometers of fiber optic cable linking the cities of London, Rotterdam, Amsterdam, Antwerp, Brussels, Paris, Dusseldorf and Frankfurt. The full 18,000 kilometer network is expected to become fully operational during the year 2000. HER also plans to lease capacity on a transatlantic cable linking the European network to North America and is exploring various interconnectivity options to Russia and Asia. Such intercontinental interconnectivity will help HER to satisfy the needs of its European customers with respect to outgoing traffic and to attract additional non-European customers with traffic terminating in Europe. HER commenced commercial service over the Brussels-Amsterdam portion of the network in late 1996, and the London-Paris portion in November 1997. GTS-Monaco Access operates an international gateway in Monaco in partnership with, and

43

utilizing the existing gateway infrastructure of, the Principality of Monaco and provides transit and routing of international calls to other telecommunications operators. Through its HER and GTS-Monaco Access ventures, GTS is building a new network for transporting voice, data and multimedia/image traffic for other carriers throughout Western and Central Europe and for worldwide international voice, data and multimedia/image traffic that either originates or terminates in, or transits through, Western and Central Europe. See " -- Western Europe."

In Central Europe, GTS's objective is to become one of the leading alternative telecommunications providers in the region. GTS currently provides private data communications services to government and commercial customers in Hungary and the Czech Republic. In the Czech Republic, the Company provides outgoing voice services and operates an international gateway and a data services network. In Hungary, GTS operates a VSAT network, which GTS believes is the largest VSAT network in Central Europe as measured by number of VSAT sites. The Company has also signed an agreement to provide international data services in Poland, subject to the receipt of necessary governmental approvals. GTS's strategy is to expand its service offerings as the regulatory environment permits, leverage its existing VSAT and international gateway infrastructure where possible and provide a broad range of services to its target markets. See " -- Central Europe."

Although GTS does not currently own or operate significant telecommunication assets in Asia, GTS's objective is to become an established and diversified telecommunications provider in China and India. GTS seeks to leverage its position in these countries to capitalize on opportunities as they arise. See "-- Asia."

BUSINESS STRATEGY

GTS seeks to develop businesses to meet the rapidly expanding market demand for telecommunications services. GTS's goal in emerging markets is to establish itself as the leading alternative to the incumbent telecommunications service providers and as a premier provider of value-added services. In addition, the Company seeks to position itself as the leading independent carriers' carrier within Western and Central Europe through the development of a pan-European fiber optic network and an international gateway in Monaco.

GTS believes that it will be able to successfully operate its businesses and develop business opportunities by pursuing the following strategies:

- Identify and Seize Early Market Opportunities. GTS's primary strategy is to identify less developed markets in which the incumbent operator offers inadequate service and where liberalization of telecommunications regulations may be pending. The Company believes entering these less developed markets quickly is a key competitive advantage in the global telecommunications market. GTS leverages its management's knowledge of the markets in which the Company operates to assess and react quickly when attractive business opportunities arise.

- Establish Joint Ventures with Experienced Local Partners. GTS seeks to establish and maintain strategic partnerships and relationships with key telecommunications operators and service providers in the countries in which it operates. The Company believes that these relationships increase its ability to anticipate and respond to changes in the regulatory and legal environment and assist with license renewal and expansion of its operating companies.

- Retain Significant Operational Control. In general, GTS actively participates in the management of its ventures by (i) providing most of the funding for the ventures' operations, (ii) selecting key members of the local management team, (iii) developing business plans and marketing strategies together with local management, (iv) monitoring operating functions, (v) maintaining close working relationships with local partners and (vi) integrating its networks and businesses in a manner which is consistent with the Company's overall strategic objectives.

- Build Infrastructure to Provide High Quality Services. GTS continues to develop and expand its network infrastructure. The Company believes that its networks offer service, quality and cost advantages over incumbent providers as a result of the Company's customer support, network monitoring, management systems and its ability to integrate and co-market its service offerings.

44

- Leverage Management Depth and Experience. GTS's management has significant experience in the development and operation of telecommunications businesses outside the United States. The Company believes that this experience, together with the Company's extensive operations, has provided its management with the ability to identify, evaluate and pursue international telecommunications business opportunities. Additionally, GTS has assembled a management team comprised of executives with extensive experience managing telecommunications companies in the respective local markets. GTS believes that its management team possesses a broad knowledge of relevant political and regulatory structures, as well as the cultural awareness and fluency with international and local business practices necessary to implement the Company's objectives.

- Ability to Access Capital. In general, the Company's financing strategy is to establish parent level funding to meet general corporate needs and the costs of start-ups and acquisitions and, when it is possible and cost-effective, to finance ongoing operations at the venture level. Since 1993, the Company has raised approximately $268 million in equity and approximately $215 million of debt (of which approximately $74 million was raised through shareholders). In addition, HER completed a $265 million private placement of senior notes (of which $56.5 million was placed in escrow for the first two years' interest payments) in 1997. The Company's principal investors include affiliates of George Soros and Alan B. Slifka and certain of his affiliates.

In addition to its overall business strategy, GTS has developed specific market strategies to achieve its goals in emerging markets and Western Europe.

Emerging Markets. The Company pursues its goals in emerging markets through a three-stage approach of market entry, market expansion and market integration.

- Market Entry. GTS identifies a market as a suitable target for entry based upon: (i) superior growth prospects for such market, demonstrated by growing demand for high quality telecommunications services; (ii) the provision of inadequate services by incumbent providers, typically resulting from the incumbents' unwillingness to offer high quality services with reliable customer support at attractive prices; and (iii) attractive regulatory environments in which emerging alternative telecommunications providers such as GTS have, or expect to have over a clearly defined time horizon, the ability to compete on a substantially equal basis with the incumbent providers in terms of certain services and the cost of providing those services. Once GTS has identified a market as suitable for entry, the Company seeks to establish its presence in that market by establishing a venture with a strong local partner or partners. In general, GTS maintains a significant degree of operational control in such ventures. Through such ventures, the Company benefits from its partners' ability to provide infrastructure, regulatory expertise and personnel that will provide GTS with a competitive advantage in entering that market. When entering a new market, GTS's strategy is to provide its customers with higher quality service as compared to the services offered by incumbent providers.

- Market Expansion. Having entered a market successfully and established a limited service offering to its targeted customer base, GTS then seeks to expand the range of services it offers to existing and potential customers and to further develop its relationships with local partners. By broadening its service offerings, GTS anticipates achieving increased economies of scale through the common use of administrative and operating functions already in place, increasing the Company's share of its customers' telecommunications spending and expanding GTS's base of potential customers through the provision of a bundled service offering. The Company also seeks to expand its targeted geographic market by forming new partnerships, installing infrastructure and offering services in additional geographic regions, allowing the Company to further enhance its operating leverage and ability to service its customers' telecommunications needs.

- Market Integration. GTS ultimately intends to integrate and co-market its service offerings in each of the markets in which it operates. The Company believes such integration enables it to enhance its operating efficiency by leveraging its distribution channels, infrastructure and networks, and management information systems. As customers develop a need for a broader variety of telecommunications services, the Company believes GTS's integrated operations will represent an attractive service

45

alternative for customers seeking a single provider with the ability to meet all their telecommunications needs.

Western Europe. The Company seeks to position itself as the leading independent carriers' carrier within Western Europe through the development of HER's pan-European fiber optic network and the operation of GTS-Monaco Access's international gateway in partnership with, and utilizing the gateway infrastructure of, the Principality of Monaco. The overall strategy of GTS in Western Europe is to complement and enhance the services provided by PTOs and New Entrants in a way that helps them to more successfully meet the needs of their end-user customers. HER seeks to enter the market ahead of competition and encourage a wide variety of carriers to use its network with service offerings that meet their needs. To establish itself as the leading carriers' carrier for international telecommunications within Europe, HER intends to provide its customers with significantly higher quality transmission and advanced network capabilities at a competitive price by utilizing advanced, uniform technology across the region and providing redundant routing for higher levels of reliability.

RUSSIA AND THE CIS

OVERVIEW

GTS is a leading provider of a broad range of telecommunications services in Russia. GTS's services include international long distance services, domestic long distance services, high speed data transmission and Internet access, cellular services and local access services. GTS was among the first foreign telecommunications operators in the CIS, where it began offering data links to the United States in 1986, international long distance services in 1992, local access to its networks in 1994 and cellular services in 1995. GTS has developed these businesses into a leading provider of telecommunications service offerings in Russia by building its own infrastructure, including a fully digital overlay network and interconnections with its local Russian telecommunications partners.

The Company believes that evolving changes in government policy over the last several years and the overall inadequacy of basic telecommunications services throughout Russia have created a significant opportunity. Before 1990, all international, domestic long distance and local telecommunications in the Soviet Union were provided by a monopoly state telecommunications company managed by the Ministry of Posts and Communications. In 1990, the Council of Ministers established a joint-stock company called Sovtelecom and transferred to it all of the telecommunications assets and operations of the Soviet Ministry of Posts and Communications. Following the dissolution of the Soviet Union in 1991, the name of the company was changed to Intertelecom. In 1992, the Russian government decided to split Intertelecom into several components to foster privatization, competition and investment. The international and long-distance assets and operations were combined into Rostelecom, creating a monopolistic service provider. The local telecommunications assets and operations were broken up into 88 independent regional joint-stock companies, seven of which serve cities, including the Moscow City Telephone Network and the Petersburg Telephone Network. Most of the regional companies have a telecommunications trunk operator and provide a domestic long distance service within their service region. Domestic long distance calls to and from areas outside the companies' service area, as well as international calls, are switched to and from Rostelecom, which forwards the calls to and from another regional company or a foreign carrier for international calls. Exceptions to this rule include the seven city operators. In Moscow and St. Petersburg, the trunk operators have been isolated into separate, long distance companies called Moscow MMT and St. Petersburg MMT. All domestic long distance and international calls originating from or terminating in Moscow and St. Petersburg are switched through the MMTs, which forward the calls to and from Rostelecom.

Following the former Soviet Union's transformation from a centralized economy to a more market-oriented economy, increased demand from emerging private businesses and from individuals, together with the poor state of the public telephone network, has led to rapid growth in the telecommunications sector in Russia and the CIS. In 1991 the MOC was established as the Russian successor to the Soviet Ministry of Posts and Communications to regulate and improve the telecommunications industry and to be the government's representative for its ownership share of the 88 regional operating companies, the assets currently held by

46

Svyazinvest (then the monopoly international and domestic long distance service provider) and national radio, television and satellite operating companies. This enabled the MOC and operating organizations to begin the privatization process, attract foreign investment and initiate joint ventures with foreign partners.

Although it remains subject to certain restrictions, significant progress in privatization of the telecommunications industry in Russia and the CIS has occurred. Under Russian law, state-owned enterprises within the telecommunications sector were subject to privatization but only pursuant to a decision of the Russian government in each individual case and with the state retaining a certain percentage of the stock of the privatized entity for three years, subject to extension for national security reasons. At present, virtually all of the former state telecommunications enterprises have been privatized and, subject to the above restrictions, shares of the newly formed joint stock companies have been sold to the public. Also, a significant number of private operators provide a wide variety of telecommunications services pursuant to licenses from the MOC to a growing number of customers throughout Russia. According to the MOC, more than 6,000 licenses have been granted to telecommunications operators in Russia, a large portion of which is assumed to represent licenses reissued to the same operators as a result of their reorganization or obligation to hold such licenses on counterfeit-proof paper.

In October 1994, the President authorized the establishment of Svyazinvest with the stated purpose of fostering greater efficiency and economies of scale within the industry through competition. As a wholly government-owned company, Svyazinvest was granted a controlling stake in approximately 85 regional telecommunications companies in order to compete in these respective markets. Svyazinvest was also given control of more than 20 million of the 25.5 million telephone lines in Russia, except in Moscow and St. Petersburg.

In April 1997, President Yeltsin approved the transfer of the federal government's 51% stake in Rostelecom, as well as similar stakes in Central Telegraph (the national PTO), the Yekaterinberg City Telephone Network and Giprosvyaz (a telecommunications research institute), to Svyazinvest. On July 30, 1997, Mustcom Ltd., a Cyprus-based company that represents the interests of a consortium which includes ICFI Cyprus, Renaissance International Ltd., Deutsche Morgan Grenfell, Morgan Stanley, and an affiliate of George Soros, purchased a 25% stake in Svyazinvest for $1.87 billion. The President has also authorized the sale of another 24% of Svyazinvest at a future date. This sale is scheduled to occur in the first half of 1998 and is currently reserved solely for Russian investors. The Russian government has announced that it will retain a controlling 51% interest in Svyazinvest.

The Russian government's interest in Svyazinvest is held by the MOC, which was reclassified as the State Committee on Telecommunications and Informatics during a recent government reorganization. The MOC remains the central body of federal authority in the Russian Federation, having responsibility for state management of the communications industry and supervisory responsibility for the condition and development of all types of communications.

Despite the recent changes in the Russian telecommunications industry, the level of telecommunications service generally available from most public operators in Moscow remains significantly below that available in cities of Western Europe and the United States, although in recent years, the Moscow local telephone infrastructure has benefitted from significant capital investment. By 1995, there were approximately 16 lines per 100 persons in Russia and 45 lines per 100 persons in Moscow. In comparison, there were 60 and 58 lines per 100 persons in the United States and Western Europe, respectively. In addition, the quality of services, reflected as the percentage of digital switching in local telephone networks, currently is approximately 12% in Russia compared to 65% and 66% in the United States and Western Europe, respectively.

Outside Moscow (and to a lesser extent St. Petersburg), most standard Russian telecommunications equipment is obsolete. For example, many of the telephone exchanges are electromechanical and most telephones still use pulse dialing. The Russian population is over 145 million, of which approximately two- thirds is concentrated in urban areas. The telecommunications market in Russia currently includes a number of operators that compete in different service offering segments -- local, inter-city, international, data and cellular services. In large measure, the relative lack of economic development in the regions accounts for the lack of improvement in local telecommunications infrastructure. Although the regions still generally rely on an

47

outdated infrastructure inherited from the former Soviet Union, they are starting to resort to sophisticated sources of finance, such as municipal bond offerings, in order to upgrade it.

Growth in the Russian telecommunications industry has been principally driven by businesses in Moscow requiring international and domestic long distance voice and data services and by consumers using mobile telephony. This growth has been most significant as multinational corporations have established a presence in Moscow and Russian businesses have begun to expand. The service sector, which includes operations in distribution, financial services and professional services and tends to be the most telecommunications-intensive service sector of the economy, is growing rapidly in Moscow. Since moving to a more market-oriented economy, the economic conditions in the outlying regions in Russia have also generally improved. The telecommunications industry in the outlying regions has experienced recent growth, principally as a result of growth in the industrial sector as well as the establishment of satellite offices in the regions by multinational corporations and growing Russian businesses. The extent of overall market growth will depend in part on the rate at which the Russian economy expands, although recent revenue growth in the sector has been significant (in spite of a declining economy in certain regions) because of increasing traffic from pre-existing customers and the normalization of tariffs for business services.

The Company believes it is well-positioned to take advantage of market growth factors due to (i) its early market entry, (ii) its strong infrastructure position in Moscow, by far the most important regional market, (iii) the local market experience of its local partners, (iv) the extent of its existing customer base and (v) its extensive range of international and domestic telecommunications services. GTS believes it is the only operator in Russia currently capable of providing a broad range of service offerings and marketing them as a single end-to-end service offering for its customers.

STRATEGY

GTS's objective is to become the premier alternative carrier in Russia and other key growth markets of the CIS. To attain this objective, the Company has developed and implemented the following strategy:

- Develop Strong Local Partnerships. The Company has and continues to develop its Russian and CIS business through alliances with experienced local partners, which to date have been primarily regional telephone companies and Rostelecom. These ventures combine the management, financial and marketing expertise of GTS together with its partner's ability to provide infrastructure and local regulatory experience. GTS believes that these relationships lend it credibility and increase its ability to anticipate and respond to the evolving regulatory and legal environment. GTS maintains a significant degree of managerial and operational control in its joint ventures through its foundation documents, which enable GTS to develop them in a manner consistent with its overall strategic objectives.

- Expand Customer Base. The Company continues to expand its customer base through the provision of basic telephone and digital services in markets where such services are not currently provided. Once they have established a presence in a market, the Company's ventures seek for opportunities to expand further into neighboring regions and cities.

- Increase Range of Digital Services. As its business customers expand their operations throughout Russia and the CIS and as their telecommunications needs become more sophisticated, the Company seeks to increase its revenues by expanding the range of integrated digital services offered to its customers.

- Offer High Quality Telecommunications Service and Customer Service. The Company continues to invest in and build sophisticated high-speed digital networks and other infrastructure through which customers can gain local access to the Company's services. In addition to providing advanced, high quality network infrastructure, the Company emphasizes and offers its customers a level of customer service which the Company believes cannot be found elsewhere in the market.

To date, GTS has made substantial progress employing this strategy. The Company provides digital voice, data and local services in Moscow through its Sovintel, Sovam and TCM ventures and provides these same services to thirteen additional Russian cities through its TeleRoss long distance network.

48

OPERATIONS

GTS provides a broad range of telecommunications services in Russia, including international long distance services, domestic long distance services, cellular services, high speed data transmission, Internet access and local access services. These services are supported by operator assistance, itemized call reporting and billing, and other value-added capabilities that leverage GTS's investment in advanced switching, data collection and processing equipment. GTS also provides customized systems integration, including PABXs, key systems, wiring and interconnectivity. GTS's own infrastructure is supplemented with dedicated and leased capacity to allow GTS to bypass the severely congested and poorly maintained local, domestic and long distance circuits of the Russian carriers.

Whenever practical, GTS's business units integrate and co-market their service offerings, utilizing TeleRoss as the long distance provider, Sovintel as the international gateway, TCM and GTS Cellular for local access, and Sovam as the data communications and Internet access network for business applications and on-line services. Through this integrated marketing approach, GTS is able to provide comprehensive telecommunications solutions to multinational corporations operating throughout Russia and the CIS.

The following table sets forth certain operating data related to the Company's operating ventures in Russia and the CIS.

(1) In 1994, the Company's interest in ventures operating in Russia consisted of a ten-percent interest in Baltic Communications Limited, a one-third interest in Sovam, and Sovintel, in which the Company owned a 12.5% interest through May 1994 and a 50% interest thereafter.

(2) Amounts include minutes between Company affiliates.

(3) International and inter-city long distance outgoing minutes not segregated in 1994.

SOVINTEL

GTS owns 50% of Sovintel, a joint venture with Rostelecom, the national long distance carrier. Sovintel was founded in 1990 by GTS, Rostelecom and GTE Spacenet, with GTS acquiring GTE Spacenet's interest in 1994. Sovintel markets a broad range of high quality telecommunications services by (i) directly providing international direct dial access to over 170 countries and private line dedicated voice channels and (ii) leveraging the infrastructure and services of the other GTS ventures, including TeleRoss, TCM and Sovam. In addition, Sovintel provides and installs for its customers equipment such as PABXs, key systems and wiring and provides maintenance and other value-added services. Sovintel customers, which primarily consist of businesses, hotels and Moscow-based cellular operators, are able to access these telecommunications services through Sovintel's fully-digital overlay network in Moscow. In addition, Sovintel has recently commenced construction of a limited network in St. Petersburg that is interconnected to Sovintel's Moscow network and is intended to support Sovintel's Moscow clients which have a presence in St. Petersburg. Sovintel serviced over 40,500 telephone numbers, or "ports," for business customers and cellular providers and had over 240 employees as of September 30, 1997.

49

Sovintel has constructed and operates a fully-digital overlay network in and around Moscow which consists of (i) an approximately 600-kilometer fiber optic ring, (ii) over 250 PABXs linked to the fiber optic ring, (iii) a fully-digital microwave network, (iv) a wireless local loop and (v) an international gateway connected to the fiber optic ring. In addition, Sovintel leases dedicated international long distance channels. Customers are connected to the Sovintel network via last mile connections to over 250 PABXs that provide "points-of-presence" in and around Moscow. The PABXs are connected to the network through a direct fiber connection or a digital microwave network. Some of Sovintel's new customers are temporarily connected to the network through a wireless local loop. The wireless local loop provides a significant competitive advantage because it allows Sovintel to connect customers to its network more quickly than alternative methods. As these customers are provided permanent connections to Sovintel's network through direct connections to the PABXs, additional customers are rolled onto the wireless local loop.

[GTS SOVINTEL MOSCOW NETWORK]

After a customer is connected to the Sovintel network, local telephone services are provided through the Sovintel fiber optic ring's interconnection with the switches of either TCM or MTU Inform. These switches provide access to local telephone service in Moscow through interconnections with the Moscow city telephone network ("MGTS") and the principal Moscow cellular providers. Sovintel provides its customers access to domestic long distance service through the TeleRoss long distance network, or through Rostelecom's network in cities not currently served by TeleRoss. International service is provided primarily through the Sovintel international gateway, which transmits international traffic via dedicated international leased long distance channels. Sovintel's customers also can receive high speed data services through Sovintel's interconnection with the Sovam data network. Accordingly, from a customer's perspective, Sovintel offers a broad range of telecommunication services.

Services. Sovintel markets a broad range of high quality telecommunications services by (i) directly providing international direct dial access to over 170 countries and private line dedicated voice services and (ii) by leveraging the infrastructure and services of the other GTS ventures. Sovintel's services include:

- Switched International, Domestic Long Distance and Local Services. Customers are provided switched international long distance services directly through Sovintel's international gateway in Moscow and its leased long distance channels. Domestic long distance services are marketed by Sovintel and provided either through the TeleRoss long distance network or, where the call destination is not served by TeleRoss, through Rostelecom's network. Local call service is provided by Sovintel indirectly as a result of its interconnection, through TCM or MTU Inform, with the Moscow city telephone network. Based on its familiarity with the market, the Company believes that Sovintel's services are distinguished by a higher level of quality than those of its competitors, particularly with respect to call completion rates for its domestic long distance and local call services. In addition, the Company trains its employees to provide customer service at a level which is comparable to that provided by Western telecommunications companies. As a result, the Company believes that customers choose Sovintel over its competitors because it has earned a reputation for providing high quality telecommunications services through an experienced and professional customer service staff.

- Private Line Channels. Private line channels, which are provided over dedicated leased lines, are principally utilized by customers with high-volume data traffic needs, such as Sovam and large data providers. Private line customers have access to intra-city service in Moscow through Sovintel's fiber optic ring and to inter-city service between Moscow and St. Petersburg via fiber leased by Sovintel, in

51

each case benefitting from Sovintel's high quality infrastructure. Private line domestic long distance service is provided through TeleRoss and, for cities not served by TeleRoss, through Rostelecom. International private line service is provided through dedicated leased fiber channels from Rostelecom.

- Equipment Sales, Installation Services and Project Planning and Management Services. In providing the above services to its customers, Sovintel installs and maintains equipment on its customers' premises, including PABXs, key systems and wiring. Sovintel also provides project planning and management services, including system design and management, to its customers.

- World Access Service. Customers are able to access Sovintel's international long distance services through the World Access Card, which provides customers either direct or calling-card-based portable access to domestic and international long distance service. The calling card can be used in 15 Russian cities, including Moscow and St. Petersburg, and 23 countries.

Sovintel complements its service offerings by providing a wide range of value-added services including operator assistance, maintenance and customer support and itemized call reporting and billing.

Customers and Pricing. Sovintel's customers consist primarily of high-volume business and professional customers, such as IBM, Credit Suisse Group and Reuters, other multinational corporations and Russian enterprises, a number of premium Moscow hotels and other telecommunications carriers. In addition, Sovintel is one of the primary providers of domestic and international long distance service for the major cellular service providers in Moscow, including VimpelCom, MTS and Moscow Cellular. Sovintel's customers typically demand a higher level of service than generally available in the market. Sovintel further provides to its large corporate customers data services such as frame relay and Internet access contracted from Sovam in order to offer "one-stop shopping" telecommunications solution to these customers, who increasingly require this type of service.

The pricing structure for international and domestic long distance calls is based upon traffic volume and overall market rates, with Sovintel's rates varying depending on the time and destination of the call. Local calls, other than calls placed to cellular phones, are completed without charge. Sovintel expects to continue its practice of not charging to complete local calls unless and until the MGTS begins to charge for completion of such calls. Sovintel prices its international long distance services slightly below those of its principal competitors, and has recently reduced its rates in anticipation of increased competitive pricing pressures. Sovintel's average revenue per minute for outgoing international long distance calls has declined from approximately $2.35 per minute for the year ended December 31, 1994 to approximately $1.19 per minute for the nine months ended September 30, 1997. Sovintel expects increased pricing pressure from competitors over time. Sovintel prices domestic long distance services in line with those of its principal competitors. Prices for domestic long distance services have increased significantly over the last several years, although such prices stabilized in the second half of 1996. Sovintel's private line services are priced competitively. Sovintel provides private line channels by releasing lines it leases from Rostelecom. The lines are leased by Sovintel from Rostelecom at wholesale rates and leased by Sovintel to its customers at prices in line with Rostelecom's retail rate.

Customers are billed monthly with larger-volume customers receiving discounts of up to 25%. Customers using international services, domestic long distance or data services are billed in U.S. dollars. To the extent permitted by law, payment is made either in U.S. dollars or in rubles at the ruble/dollar exchange rate at the time of payment, plus a conversion charge in order to minimize the impact of currency fluctuations. Sovintel currently bills on an invoicing system that was internally developed. Currently, the system is adequate for Sovintel's present customer base; however, the Company is evaluating alternatives for upgrading the system in anticipation of future growth.

Sales and Marketing. Sovintel's sales and marketing strategy targets large multinational and Russian businesses both directly and through contacts with real estate developers and business center managers in the greater Moscow area. These developers and managers typically determine which telecommunications service provider will service their respective properties. By identifying and building relationships with these developers and managers at an early stage (typically up to one year prior to the completion of a new building project),

52

Sovintel seeks to enhance the likelihood of winning the service contract. In addition to its traditional target market, Sovintel has recently begun to market its services to smaller businesses. Sovintel utilizes a departmentalized sales force in order to focus its sale efforts on the different segments within its target market. The sales force is comprised of 40 sales personnel, including 15 account managers, all of whom specialize in serving specific targeted industries. Dedicated marketing and customer support personnel provide technical support, customer service, training, market monitoring and promotional functions for Sovintel. Sovintel's sales and marketing personnel are paid through a combination of salary, commissions and incentive bonuses.

Ownership and Control. Sovintel is a joint venture between a wholly-owned entity of GTS and Rostelecom with each having a 50% ownership interest. Under Sovintel's charter, GTS and Rostelecom each have the right to appoint three of the six members of Sovintel's managing board. Rostelecom has the right to nominate the Director General (the highest ranking executive officer at Sovintel), while GTS has the right to nominate the First Deputy Director General (the next-highest ranking executive officer at Sovintel). In practice, the Director General and the First Deputy Director General together perform the role of a chief executive officer. Certain business decisions, including the adoption of Sovintel's annual budget and business plan as well as the distribution of profits and losses require the approval of both GTS and Rostelecom. Neither GTS nor Rostelecom are obligated to fund Sovintel's operations or capital expenditures. Losses and profits of Sovintel are allocated to the partners in accordance with their ownership percentages, in consideration of funds at risk. As of September 30, 1997, GTS and Rostelecom has each made equity contributions of $1.0 million to Sovintel. In addition, Sovintel had outstanding loans of $9.0 million to GTS as of September 30, 1997. See "Management's Discussion and Analysis -- Accounting Methodology -- Profit and Loss Accounting." The Sovintel joint venture agreement does not have an expiration date. See "Risk Factors -- Dependence on Certain Local Parties; Absence of Control."

TCM

GTS beneficially owns approximately 50% of TCM, a joint venture founded in 1994 that provides a licensed numbering plan and interconnection to the Moscow city telephone network for carriers needing basic local access service in Moscow. GTS's partners in TCM are MTU-Inform and a group of entrepreneurs with extensive telecommunications experience. TCM is currently licensed to provide 100,000 numbers in Moscow, of which approximately 44,000 have been leased. TCM has contracted with MGTS to construct up to an additional 100,000 numbers in several stages over the next five years, and currently plans to construct 10,000 numbers in each of 2000, 2001 and 2002. Any such construction, however, is subject to TCM obtaining a license covering the additional numbers and the availability of such numbers in the portion of the MGTS numbering plan in which TCM plans to construct such numbers. TCM's switching facilities are fully integrated with the networks of Rostelecom, Sovintel, and MGTS, allowing it to provide high quality digital service to its customers.

Services. TCM acts as a local gateway by providing numbers and ports to carriers in Moscow, including Sovintel, VimpelCom, MTS and Moscow Cellular, and thus providing interconnectivity to the Moscow city telephone network. Access to the Moscow city telephone network provides customers with the higher quality and broader range of services available in Moscow, such as the services provided by Sovintel. Access from outlying regions is typically obtained through a domestic long distance service provider such as TeleRoss. See "-- Sovintel" and "-- TeleRoss."

Customers and Pricing. TCM provides its services on the wholesale level to primary carriers. VimpelCom is TCM's primary customer and accounts for substantially all of TCM's revenues, hence the loss of VimpelCom as a customer would have a material adverse effect on the Company. TCM also provides ports to Sovintel and to other network operators including MTS and Moscow Cellular. TCM's ports are leased principally to carriers in Moscow. Although local access services are priced upon the basis of supply and demand factors in the local market, in general, for each port cellular operators pay an approximately $300 installation fee and a $16 flat monthly fee plus a per minute charge for traffic while other carriers pay a larger initial fee of approximately $500 and a monthly fee of approximately $25. Local access services are typically provided pursuant to five-year contracts that may be renewed upon expiration for additional one-year periods. TCM has entered into an agreement with Sovintel pursuant to which billing and collecting functions

53

for TCM-Sovintel joint customers are performed by Sovintel, with Sovintel remitting such amounts (less applicable settlement charges and administrative costs) to TCM. The rapid growth of cellular services in markets like Moscow has placed a premium on new numbers, which has translated into attractive prices for these numbers. TCM, however, believes these prices will decline over time.

Ownership and Control. GTS's indirect interest in TCM is represented by its approximately 52% interest in a holding company, which owns 95% of TCM. This structure provides GTS with 50% beneficial ownership interest in TCM. Decisions of the holding company regarding TCM require unanimous board approval and neither GTS nor its partner in the holding company is obligated to fund operations or capital expenditures of the holding company. In addition, neither the holding company nor the TCM shareholders are obligated to fund operations or capital expenditures of TCM. At both the holding company and TCM level, losses and profits are allocated to the partners in accordance with their ownership percentages, in consideration of funds at risk. GTS acquired its indirect, 50% beneficial interest in TCM for approximately $700,000 and certain additional consideration. As of September 30, 1997, GTS had no outstanding loans relating to TCM. See "Management's Discussion and Analysis -- Accounting Methodology -- Profit and Loss Accounting." None of the operative charters and agreements relating to the holding company or TCM have expiration dates. See "Risk Factors -- Dependence on Certain Local Parties; Absence of Control."

TELEROSS

TeleRoss, which began operations in 1995, consists of (i) two wholly-owned holding companies and a 99% owned subsidiary of GTS that operates a domestic long distance network (collectively, the "TeleRoss Operating Company") and (ii) thirteen joint ventures that are 50% beneficially-owned by GTS that originate traffic and provide local termination of calls (the "TeleRoss Ventures" and, together with TeleRoss Operating Company, "TeleRoss"). The TeleRoss domestic long distance network serves fourteen major Russian cities, including Moscow and, through VSAT technology, 19 customers located outside these cities. TeleRoss provides digital domestic long distance services and other value-added services through its own infrastructure as well as access to Sovintel's international gateway services and access to the Moscow city telephone network through TCM's switching facilities. Sovam uses the TeleRoss digital channels to provide regional data service and has co-located its access facilities with TeleRoss. As of September 30, 1997, TeleRoss employed approximately 188 persons of which approximately 90 people were based in Moscow and approximately 98 people were deployed in the regions in which TeleRoss operates.

54

TeleRoss's licenses cover the city of Moscow and a total of 39 regions throughout Russia. Most of the thirteen cities in which TeleRoss primarily operates are regional capitals, with an aggregate population of approximately 11.5 million. TeleRoss's licenses cover the entire oblast surrounding these cities, with populations totalling approximately 38.1 million persons, and GTS intends eventually to extend the reach of the TeleRoss network beyond the regional capitals to the surrounding areas. The cities in which TeleRoss currently offers its services are:

The TeleRoss network architecture involves local city switches connected to remote earth stations which communicate via satellite to a Moscow-based hub. This hub consists of the network control center, earth station equipment, multiplexing equipment and a switch. The earth stations, hub and related equipment are owned by TeleRoss, which gives TeleRoss the flexibility to redeploy network assets to other locations as necessary. The hub interconnects to Sovintel's network providing access to Sovam's data networks, TCM's switching facilities and Sovintel's international gateway, which transports international traffic via dedicated international leased satellites and fiber channels and provides access to Rostelecom's long distance networks. Outside of Moscow, TeleRoss's local joint venture partners provide interconnection to the local public telephone networks in each of the cities it serves. In addition to providing services through its network, TeleRoss currently serves 19 customers in 18 additional cities through VSAT technology which links the customers via satellite to the Moscow hub.

Services. Through its network and VSAT offerings, TeleRoss offers the following services:

- Carriers' Carrier Services. TeleRoss provides services as a "carriers' carrier," providing domestic long distance carrier services to cellular operators, Sovintel, the TeleRoss Ventures' regional partners and competitive bypass operators from the cities in which the TeleRoss Ventures operate, and to customers in remote cities using VSAT stations. These services are provided to and from Moscow, and are provided by TeleRoss at wholesale rates competitive with those offered by Rostelecom. TeleRoss also provides private line channels to Sovam in cities where the TeleRoss Ventures operate. In addition, TeleRoss has recently received a license to provide international private line service.

- World Connect Dial/Russia Connect Dial. Customers in TeleRoss's cities are provided dedicated local access to the regional TeleRoss switch through lines leased from the TeleRoss Venture's regional joint venture partner. These customers then have access to the domestic long distance service provided by TeleRoss, international long distance service provided by Sovintel and are fully integrated into the local phone networks operated by the applicable TeleRoss Venture's partner and to the Moscow city telephone network through TCM.

- Moscow Connect. Customers are provided with dedicated last mile connection over lines leased from the regional joint venture partner which lines are connected to a local TeleRoss switch. The TeleRoss network and its interconnection to TCM provide customers with a Moscow dial tone which allows users in remote locations better access to Moscow's advanced telecommunications infrastructure. In addition, Moscow Connect service provides better call quality at lower rates for domestic and international long distance. Moscow Connect also facilitates communications between users and their

56

Moscow-based associates as calls can be made to and from Moscow without the use of prefixes and without long distance charges accruing to the Moscow-based parties.

- Dedicated Circuits. Customers are provided with point-to-point clear channel circuits within Russia and internationally through the TeleRoss backbone and its interconnection with Sovintel's international gateway in Moscow. Dedicated circuits are generally used by news services, banks and other commercial customers who require high capacity and high quality service. This service can be used for voice or data, depending on the user's needs. In providing dedicated circuits, TeleRoss competes against other alternative communications providers, however, TeleRoss believes that it has a distinct price advantage over its competitors because of the use of its own infrastructure and the bulk purchase of satellite capacity.

- World Access Service. TeleRoss and Sovintel co-market World Access Service to their customers in each of the cities they serve through two products: World Access Direct and World Access Card. Through World Access Direct, TeleRoss customers can access domestic long distance and international service anywhere within the customer's city through the local telephone network. The World Access Card is a calling card which allows TeleRoss customers portable access to domestic long distance and international service from 15 Russian cities, including Moscow and St. Petersburg, and 23 countries. This service is provided through Sovintel's infrastructure.

- VSAT Services. For customers that are located outside the cities serviced by TeleRoss or that cannot be physically linked to TeleRoss's regional switches, TeleRoss offers VSAT service which connects these customers directly to TeleRoss's Moscow-based hub through a VSAT antenna installed at the customer's location. Both dedicated and switched services are provided through these VSAT arrangements.

In addition to continuing the development of its core domestic long distance business, TeleRoss's strategy includes the development of local access networks to capitalize on demand for local phone service and to capture additional customers for its long distance and value-added service offerings. Outside Moscow, TeleRoss has primarily pursued a strategy whereby it develops its own intra-city trunking network with copper based or fiber optic facilities leased from the regional joint venture partners. As of September 30, 1997, TeleRoss, in conjunction with regional joint venture partners, has installed approximately 25 kilometers of fiber optic cable in 3 cities and plans to install an aggregate of approximately 100 kilometers of additional fiber optic cable in up to an additional 6 cities over the next 24 to 30 months. Customers who obtain local phone numbers from TeleRoss's venture partners are directly interconnected to the local telephone company and to the Company's long distance network and Sovintel's international gateway and may obtain a broad range of value-added services offered by the Company.

Customers and Pricing. TeleRoss's customers include businesses and other telecommunications service providers such as carriers, PTOs, cellular operators, Sovintel and Sovam. TeleRoss's business customers consist of large multinational and Russian businesses in each of the regions it services, as well as medium and small-sized businesses. Between 1993 and mid-1996, consumer prices in TeleRoss's industry increased significantly as a result of Rostelecom raising its prices in an effort to raise capital for investment and development of its network infrastructure, although prices have stabilized over the past six months. In the first nine months of 1997, TeleRoss increased sales to carriers, which sales were made at wholesale rates, resulting in a decrease in the average rate per minute for TeleRoss. TeleRoss strategically prices its domestic long distance services at a slight premium over similar services offered by Rostelecom to account for a higher quality of service, but in line with the prices offered by regional competitors.

Sales and Marketing. TeleRoss markets its services to carriers and businesses through direct sales channels. As of September 30, 1997, TeleRoss employed 27 sales and marketing personnel, approximately half of which are based in Moscow with the other half deployed regionally to identify and contact prospective customers. The Moscow-based sales and marketing personnel are organized into industry groups in order to better identify and serve customer needs. Each region is typically served by one or two sales representatives. TeleRoss's sales efforts are supported by market research and promotional activities carried out at the joint venture level and tailored to the specific market base of each region. TeleRoss's marketing strategy is to attract

57

carrier customers by focusing on those carriers with high volume minutes operating in regions where TeleRoss has a competitive advantage. Through cross-marketing agreements with Sovintel and Sovam, TeleRoss markets many of the other service offerings of GTS's Russian businesses to customers throughout its service regions. Billing functions and the monitoring of quality control and technical issues are performed centrally through the Moscow-based hub.

Ownership and Control. TeleRoss consists of the TeleRoss Operating Company, and the 50% beneficially-owned TeleRoss Ventures. GTS controls TeleRoss Operating Company (which holds the network license) and co-manages the TeleRoss Ventures under the terms of the applicable TeleRoss Ventures' foundation agreements and charters. Under some of these charters, GTS generally has the right to designate the Chairman of the board of directors, and GTS's local partner has the right to designate the Deputy Chairman, for the first two-year term (and thereafter GTS and the local partner nominate the Chairman and Deputy Chairman for approval by the entire board on a rotating basis). The foundation agreements and charters do not have expiration dates. While GTS has significant influence within these ventures, decisions, including the decision to declare and pay dividends, are generally subject to GTS's partner's approval. See "Risk Factors -- Dependence on Certain Local Parties; Absence of Control." Neither GTS nor its respective joint venture partners are obligated to fund operations or capital expenditures of the TeleRoss Ventures. Losses and profits are allocated to the partners in accordance with their ownership percentages, in consideration of funds at risk. As of September 30, 1997, GTS and its partners had each made equity contributions aggregating $1.7 million to the various TeleRoss Ventures. Contributions made by the partners include contributions of cash and intangible assets, such as licenses. In addition, the various TeleRoss Ventures had outstanding loans of $3.3 million to GTS as of September 30, 1997. See "Management's Discussion and Analysis -- Accounting Methodology -- Profit and Loss Accounting."

SOVAM

Sovam is a venture owned 66.7% by GTS and 33.3% by the Institute for Automated Systems ("IAS"). Sovam was founded in 1990 as a venture equally owned by GTS and IAS. In 1992, Cable & Wireless acquired a 33% ownership interest in Sovam, which interest was subsequently acquired by GTS in 1994, bringing GTS's ownership interest to its current 66.7%. GTS has reached an agreement in principle to purchase IAS's interest in Sovam and expects to consummate the transaction in January 1998, thereby making Sovam a wholly owned subsidiary of GTS. Sovam provides high-speed data communications services, electronic mail and database access over a high-speed packet/frame relay network in 30 major Russian and CIS cities. Sovam also offers Russia On Line, the first Russian language Internet service, which provides direct access to the Internet as well as access to a wide range of local and international information services and databases. As of September 30, 1997, Sovam had approximately 1,667 data service customers and approximately 3,272 Russia On Line customers. Sovam employed over 100 persons in Moscow and other regions of the CIS as of September 30, 1997. Sovam provides equipment and maintains marketing and technical support personnel at each location either through its own infrastructure or through the infrastructure of TeleRoss.

In addition to serving the Moscow and St. Petersburg markets, Sovam co-locates its operations with the TeleRoss Ventures, offering its services in all TeleRoss cities, and also serves 15 additional cities in Russia and the CIS. Sovam operates under its own license within Russia while services elsewhere in the CIS are provided through applicable joint venture or local partner licenses. The local partners of the TeleRoss Ventures provide facilities, assist in the provision of leased lines to Sovam customers that allow them to connect with Sovam's local data switches and also provide technical support. Sovam utilizes Sovintel's international capabilities and, in TeleRoss-served locations, TeleRoss's satellite overlay network, to take data through its local data switches and over the leased lines to its customers. Customers may obtain virtual private data networks without investing in, acquiring, installing and maintaining their own network nodes and switches.

Services. Sovam's service offerings are comprised of data services, equipment and hardware sales and its Russia On Line services.

- Data Services. Sovam provided high speed connectivity, electronic mail, database access and fax services to approximately 1,667 customers as of September 30, 1997, in Russia and the CIS. Sovam customers can use electronic mail systems to send and receive messages and data and to access public and private data networks (including the Internet) worldwide. Customers may obtain virtual private data networks without investing in, acquiring, installing and maintaining their own network nodes and switches. In addition, Sovam offers its customers value-added data services. For example, Sovam offers "one-stop shopping" for hardware, software, installation and maintenance support and products such as "SovamMail," an e-mail service which allows customers to use Sovam's data network to send telex or facsimile messages to overseas recipients worldwide. Data services are currently available in 30 cities throughout Russia and the CIS, including Moscow, St. Petersburg, each of the cities served by TeleRoss and some cities outside of the TeleRoss network.

- Equipment and Hardware Sales. Sovam sells communications equipment and hardware, and provides related installation, maintenance and support functions, to its customers. Sovam's primary customers in the equipment and hardware market are banking clients who use the equipment to interface with Sovam's network.

- Russia On Line. Russia On Line is the first Russian language, as well as the first dual language, graphical user interface online service for accessing domestic and international information sources designed to appeal to a wide commercial audience. This service, which is distributed via GTS's domestic long distance infrastructure, provides customers with access to international databases (including the Internet), as well as an array of proprietary Russian and English language information services, such as news stories and market updates. Sovam had 2,606 Russia On Line subscribers as of September 30, 1997. Sovam has developed a modified version of Netscape's Internet browser, which utilizes the Cyrillic alphabet, as part of its Russia On Line package. Sovam's enhanced Russian version of Netscape's browser is provided by Sovam to its customers under a distribution agreement with Netscape. In addition, Sovam has signed a letter of intent with Microsoft whereby Microsoft has agreed to include software access to Russia On Line in its Russian version of Windows 97, which had not been released as of September 1997. Sovam has also entered into agreements with equipment

59

manufacturers, including Dell, Hewlett-Packard and U.S. Robotics, to include Russia On Line software with their products.

Customers and Pricing. Sovam's data communications customers consist primarily of banking and financial services organizations and large multinational companies, while Sovam's Russia On Line customers consist of a wide variety of commercial enterprises. Sovam charges customers an installation fee when service is commenced and a charge for any equipment which is installed. Thereafter, customers are billed on a monthly basis for leased line fees, port access charges and charges for data and Russia On Line services rendered during the month. Data services are priced on a two-tier structure with high volume users generally negotiating a flat-rate fee and lower volume uses paying a volume-based fee which on average was $446 and $675 per subscriber in 1996 and for the nine months ended September 30, 1997, respectively. Russia On Line customers pay a fixed monthly access charge plus an additional volume-based fee. Customers are billed in dollars and payment is remitted in rubles and, to the extent permitted by law, in dollars, with a 5% conversion fee added to ruble-denominated payments.

Sales and Marketing. Sovam employs a dedicated sales and marketing force comprised of 23 Russian nationals, 18 of which are based in Moscow with the remainder deployed in the other Russian and CIS regions. Salespersons are paid a fixed salary supplemented by sales commissions and performance-based bonuses. Sovam's sale efforts are focused primarily on the banking and financial communities and large multinational companies, although small and medium sized entities are also emerging as potential Sovam customers. Bundled service packages, which include Sovam's data and Internet service, Sovintel's international service and TeleRoss's long distance service, are frequently marketed together in order to offer customers a comprehensive telecommunications solution. In addition to data communications services, Sovam offers its customers hardware, installation and maintenance service and is a distributor of Northern Telecom equipment.

Ownership and Control. GTS owns 66.7% of Sovam and IAS owns the remaining 33.3%. GTS has reached an agreement in principle to purchase IAS's interest in Sovam and expects to consummate the transaction in January 1998, thereby making Sovam a wholly owned subsidiary of GTS. The Sovam managing board is comprised of three GTS representatives and two IAS representatives. Decisions of the managing board are adopted by a majority vote. Changes to the charter and certain business decisions, including decisions on distribution of profits and losses, obtaining loans and approving major transactions, require unanimous approval. See "Risk Factors -- Dependence on Certain Local Parties; Absence of Control." The Sovam charter does not have an expiration date. Neither GTS nor IAS are obligated to fund Sovam's operations or capital expenditures. Losses and profits of Sovam are allocated to the partners in accordance with their ownership percentages, in consideration of funds at risk. As of September 30, 1997, GTS and its partner had made equity contributions of $1.3 million and $0.7 million, respectively, to Sovam. In addition, Sovam had outstanding loans of $10.4 million to GTS as of September 30, 1997. See "Management's Discussion and Analysis -- Accounting Methodology -- Profit and Loss Accounting."

GTS CELLULAR

GTS Cellular operates three cellular businesses in Russia and Ukraine. In Russia, GTS has a wholly owned subsidiary Vostok Mobile, which operates eleven AMPS cellular companies in Russian regions west of the Urals under the trade name Unicel. Vostok Mobile owns between 50% and 70% of these cellular joint ventures (the "Unicel Ventures") in Russia. In addition, GTS intends to enter into the cellular markets of additional Russian regions through its Vostok Mobile venture. GTS also participates in PrimTelefone, a 50% owned joint venture that operates an NMT-450 network in Vladivostok and four other cities in the Primorsky region of Russia. In Ukraine, GTS has an approximately 25% beneficial interest in Bancomsvyaz which operates a DCS-1800 cellular network in Kiev, and an international overlay network in Ukraine. GTS Cellular entities possess licenses covering major Russian and Ukrainian markets (excluding Moscow and St. Petersburg) with an aggregate 1995 population of approximately 25 million people.

Vostok Mobile. Through Vostok Mobile, GTS participates in eleven cellular joint ventures in Russia. Vostok Mobile owns between 50% and 70% interests in each of the eleven Unicel Ventures with regional telephone companies and, in one instance, a private Russian company, owning the remaining ownership interest. The Unicel Ventures each operate an AMPS-based cellular network, which was chosen principally because of the lower licensing fees and equipment costs associated with AMPS operations. The Company believes that the Unicel Ventures' AMPS-based networks can be upgraded to digital AMPS ("D-AMPS") for an incremental capital investment. Cellular networks which utilize digital technology, such as D-AMPS, DCS and GSM offer several advantages over analog technology including improved overall signal and sound quality, improved call security, potentially lower incremental infrastructure costs for additional subscribers and the ability to provide enhanced data transmission services, such as facsimile and e-mail. Digital technology also provides increased system capacity. The ventures intend to convert to D-AMPS at such time as there exists sufficient competitive pressures and/or market demand for digital services to merit the additional investment.

AMPS technology is widely used by other cellular networks throughout Russia, making roaming commercially feasible. The Unicel Ventures have entered into roaming agreements with other AMPS-based cellular providers, which allow their subscribers to manually roam throughout Russia. Manual roaming, as opposed to automated roaming, requires subscribers to notify their local cellular providers of their travel plans

62

in order to receive roaming capability. Vostok Mobile is currently working with VimpelCom to develop automated roaming standards which will provide subscribers with automated roaming capability.

The Unicel Ventures, collectively, are licensed to provide cellular service to regions with an aggregate population of approximately 18.4 million people and the cellular networks of these ventures cover populations of approximately 6.5 million people. Over the next five years, Vostok Mobile plans to expand the coverage of the cellular networks to approximately 9.8 million people.

The Unicel Ventures are the only cellular operators in many of their respective regions. Each region, however, has the potential for three licensed operators, including one operator for each of the AMPS, NMT and GSM cellular standards, and the Company expects competition to increase in the future as the Russian economy develops and telephony demands increase. Each of the Unicel Ventures operates independently within uniform guidelines established by Vostok Mobile. The Unicel Ventures employ local engineering and marketing personnel, which helps the ventures maximize their presence in their respective markets and maintain quality control. Vostok Mobile and its ventures employed over 279 persons as of September 30, 1997, with over 240 persons employed regionally.

PrimTelefone. GTS's cellular operations in Vladivostok are conducted through PrimTelefone, a 50% owned GTS subsidiary, with the local electrosviaz owning the remaining 50%. PrimTelefone began operations in 1995 and operates an NMT-450 network in Vladivostok and four other cities in the Primorsky region. PrimTelefone entered and penetrated the Vladivostok market by leveraging its network design and full interconnection with the city telephone network. As a result, PrimTelefone's subscriber base has grown to 3,907 as of September 30, 1997 and PrimTelefone has been able to capture approximately half of the Vladivostok cellular market. PrimTelefone has also updated its billing system, which allows it to offer automated roaming. Although PrimTelefone has experienced significant growth, it does face competition. PrimTelefone's only current competitor has recently upgraded its network for more complete coverage and has been fully interconnected to the city telephone network and may prove to be more competitive in the future. PrimTelefone employs approximately 60 persons which include dedicated sales, marketing and customer service personnel.

PrimTelefone holds a license to provide cellular service to a region having a population of approximately 2.2 million people and, as of September 30, 1997, its cellular network covered an area with a population of approximately 1.2 million people. PrimTelefone plans to expand its network's coverage to approximately 1.7 million people over the next five years.

Bancomsvyaz. GTS operates in Ukraine through a 60% owned intermediate holding company which holds an approximately 49% interest in Bancomsvyaz, giving GTS an indirect approximately 25% economic interest in Bancomsvyaz. The remaining approximately 51% interest in Bancomsvyaz is owned by Bancomservice, a private company whose principals include telecommunications industry participants in Ukraine, and a Ukranian national. Bancomsvyaz is co-managed by GTS and Bancomservice, with Bancomservice appointing the General Director and GTS appointing the Chief Operating Officer, Chief Financial Officer and two Business Line directors. The current General Director has been active in the development of the telecommunications industry in Ukraine. Through Bancomsvyaz, GTS participates in the operation of a cellular network and an international overlay network. With over 96 employees, Bancomsvyaz markets its services and closely monitors technical and quality-related issues.

Cellular network. Bancomsvyaz operates a cellular network in Kiev utilizing DCS-1800 cellular technology, and operates under a cellular license that covers the Kiev oblast. Bancomsvyaz began cellular operations in 1996 by covering the city center of Kiev and expanded its coverage to include the entire city in 1997. Bamcomsvyaz currently provides automated roaming capability in the U.K. and has entered into a clearinghouse agreement with a European PTO which provides Bancomsvyaz customers with automated roaming capability with all GSM signatories with a roaming agreement with this PTO.

Bancomsvyaz holds a license to provide cellular service to a region having a population of approximately 4.5 million people and, as of September 30, 1997, its cellular network covered an area with approximately 1.7 million people. Bancomsvyaz plans to expand its network's coverage to approximately 3.2 million people over the next five years.

63

Overlay network. Bancomsvyaz provides switched traffic service through its overlay network in Kiev. Bancomsvyaz owns and operates a partitioned mobile switch for both its overlay and cellular businesses. Bancomsvyaz has seven central offices in the city and also provides last mile connections (which are primarily copper) from the central offices to customers. Local traffic is routed to the local telephone network through the mobile switch. International traffic is routed through a government-owned satellite dish to the GTS-Monaco Access international gateway. Bancomsvyaz emphasizes its high quality service and markets primarily to multinational companies, real estate developers and hotels. Bancomsvyaz is also negotiating with Sovintel to provide a link to Moscow and plans to offer VSAT-based connections to its network in the future.

Sales and Marketing. The GTS Cellular entities have entered into agreements with local distributors to more effectively reach their target markets. Particular emphasis is placed on product branding. Vostok Mobile's sales and marketing efforts are focused on the branding of its trade name, Unicel, which is marketed and promoted at the local level by each of the Unicel Ventures. By promoting the Unicel trade name, local ventures can emphasize their relationships with Vostok Mobile and the other Unicel Ventures, allowing customers to view the Unicel Ventures as integrated parts of a large cellular organization rather than as lone, independent operators. Bancomsvyaz operates under the trade name Golden Telecom.

Customers and Pricing. GTS Cellular's customers are primarily large, mid-sized and start-up businesses and wealthy individuals. Increases in the number of customers for GTS Cellular's ventures is typically linked to the economic health of the region in which such venture operates. Cellular service is generally a premium service in the cities in which GTS Cellular operates and is priced as such. Each venture begins with two tariff plans, a "standard" tariff plan and a "premium" tariff plan, which includes a fixed amount of airtime at a discounted per-minute rate. Each plan prices late night and weekend calls at off-peak rates. The Company expects that prices will decrease as competition increases. Connection fees are minimized in order to reduce license fees in AMPS regions (which are partially calculated by reference to connection fees), as well as to keep market entry costs low. GTS Cellular has benefited from high margins generated by the sale of handsets, which are marked up in line with other cellular operators in Russia and the CIS. Value-added services, such as call forwarding and conference calling, when available, are priced nominally and discounted when sold in packages. Cellular accounts are recorded in dollars and customers remit payment in rubles at the exchange rate on the date of the bill and, in instances permitted by law, in dollars. Ruble accounts generally are charged a two percent conversion fee and payments in rubles are applied at the rate of exchange on the date of payment. In order to lessen risks to its receivables, the Company and its cellular ventures require advance payment from all customers with prepayments averaging approximately $250 per customer for six to eight weeks of service.

Ownership and Control. GTS Cellular's Russian operations (except for the Vladivostok operations) are conducted through ventures that are owned between 50% and 70% by Vostok Mobile, a wholly owned subsidiary of GTS. GTS Cellular's Vladivostok and Ukrainian operations are conducted through ventures which require partner approval for most decisions. The applicable foundation agreements and charters do not have expiration dates. See "Risk Factors -- Dependence on Certain Local Parties; Absence of Control." Neither GTS nor any of its respective partners in its Vladivostok or Ukrainian operations are obligated to fund operations or capital expenditures. Losses and profits of all such ventures are allocated to the partners in accordance with their ownership percentages, in consideration of funds at risk. As of September 30, 1997, GTS and its partners had made equity contributions aggregating $15.8 million and $15.3 million, respectively, to the various GTS Cellular Ventures. Contributions made by the partners include contributions of cash and intangible assets, such as licenses. In addition, the various GTS Cellular Ventures had outstanding loans of $28.0 million to GTS as of September 30, 1997. See "Management's Discussion and Analysis -- Accounting Methodology -- Profit and Loss Accounting."

LICENSES AND REGULATORY ISSUES

Telecommunications operators in Russia are nominally subject to the regulations of the Regional Communications Committee (the "RCC"). As a practical matter, national telecommunications authorities of the individual CIS countries and certain regional and local authorities generally regulate telecommunications operators in their markets through their power to issue licenses and permits.

64

The Communications Law sets out a comprehensive legal and regulatory framework for the sector. It also sets forth general principles for the right to carry on telecommunications activities, describes government involvement in telecommunications regulation and operation, establishes the institutional framework involved in regulation and administration of telecommunications, and deals with various operational matters, such as ownership of networks, protection of fair competition, interconnection, privacy and liability. This institutional framework is implemented by separate legislation.

Licenses to provide telecommunications services are issued by the MOC on the basis of a decision by the Licensing Commission at the MOC. No new licensing regulations have been issued since the enactment of the Communications Law and in practice the MOC continues to issue licenses based on the Licensing Regulations. Under the Licensing Regulations, licenses for rendering telecommunications services may be issued and renewed for periods ranging from 3 to 10 years and several different licenses may be issued to one person. Once the licenses are received, the licensee is required to register its right to hold and operate under the license with Gossvyaznadzor, the national authority responsible for monitoring compliance with regulatory and technical norms. Renewals may be obtained upon application to the MOC and verification by appropriate government authorities that the licensee has conducted its activities in accordance with the licenses. Officials of the MOC have fairly broad discretion with respect to both the issuance and renewal procedures. Both the Communications Law and the Licensing Regulations provide that a license may not be transferred. However, regional authorities are sometimes in a practical position to limit these national authorities. In August 1995, the Russian government created Svyazinvest, a holding company, to hold the federal government's interests in the majority of Russian local telecommunications operators. Such entities at the oblast and krai levels (administrative regions within Russia) and two cities -- Moscow and St. Petersburg -- exercise significant control over their respective local telephone networks.

License procedures for the Company's cellular services include frequency licensing from the MOC through a two step process. A license must first be obtained from the MOC for permission to operate mobile cellular services on a commercial basis in a specific standard and frequency bandwidth. Thereafter, an approval to use specific frequencies within the band must be received from the State Radio Frequencies Commission. Once the licenses are received, Gossvyaznadzor confirms the rights of an operator to offer radio frequency transmissions on specific frequencies, administers type acceptance procedures for radio communications equipment and monitors compliance with licensing constraints. In each instance, the Company is required to obtain additional licenses and permits with respect to the use of equipment and the provision of services.

Telecommunications laws and regulations in Ukraine are similar in many respects to those of Russia but are subject to greater risks and uncertainties. Regulations currently prohibit foreign entities from owning more than 49% of any telecommunications operating company. GTS's Ukrainian joint venture agreements provide it with the option of purchasing an additional one percent of the cellular network if these rules are liberalized. The Ukrainian government has proposed substantial frequency permit fees in connection with providing GSM service in Ukraine. Although the government has not imposed additional fees on Bancomsvyaz's existing DCS-1800 service, there can be no assurance that such fees will not be imposed in the future.

GTS's subsidiaries and ventures hold the following licenses in Russia and Ukraine:

Switched Services. In Russia, the Company holds two licenses. The first license was reissued to Sovintel in November 1996 and authorizes Sovintel to operate as an international overlay network with the ability to interconnect with the Moscow region and St. Petersburg public switched telecommunications network ("PSTN"). This license ultimately requires Sovintel to provide service to at least 50,000 subscribers and expires in May 2000. It was amended in February 1997 to cover the Leningrad region. The second license was reissued to SFIT, Ltd., a wholly-owned subsidiary of GTS in February 1997, for provision of intercity services in 39 regions and in Moscow with ability to interconnect with the PSTN. In Kiev, Ukraine, the company holds a license for provision of overlay network services, including international services, in the name of its affiliate, Bancomsvyaz. In addition, Sovintel is an ITU recognized private operating agency ("RPOA"), which enables it to maintain a separate dialing code
(7-501) that can be directly dialed from over 170 countries. Sovintel's status as an RPOA also enables it to terminate calls directly with other operators.

65

Leased Circuits. In September 1996 the MOC issued to Sovintel a five-year license to lease local, intercity and international circuits in the territory of Moscow, Moscow region and St. Petersburg, valid until September 2001. The total amount of circuits leased is approximately 300 and may be increased up to a total authorized capacity of 2,500.

Data Services. In August 1996, the MOC reissued to Sovam a 2 1/2-year license, effective July 1996, to provide data transmission services via a dedicated network to a number of oblasts and other regions covering a large portion of Russia. The license permits a network capacity of not less than 5,000 customers, allows it to interconnect with other data transfer networks in Russia, and expires January 1, 1999.

Local Access Services. In January 1997, the MOC has licensed TCM to provide local telephone service in Moscow to not less than 100,000 subscriber local access lines. The license expires in May 2006. TCM has an agreement with MGTS to provide up to 200,000 lines, which would require an extension to its license, when its current capacity is reached.

Cellular Services. In connection with cellular operations, Russian law apportions the responsibility for regulating and licensing cellular businesses between national and regional regulators. National telecommunications regulators have been assigned the responsibility of regulating and licensing cellular businesses utilizing the GSM and NMT-450 cellular standards prevalent in Europe. These regulators have auctioned licenses to provide these services to a number of ventures that have included large, well capitalized western telecommunications providers such as U S WEST and Nokia during the last four years. Regional telecommunications authorities have been given the rights to supervise the observance of licenses by cellular businesses utilizing AMPS cellular standard service, which is prevalent in the United States. However, AMPS licenses are issued by the MOC. GTS believes that, in many instances, cellular operators obtaining AMPS standard licenses, particularly those in second tier cities, pay license fees that are lower than those paid for the GSM and NMT-450 "national standards". Licenses for cellular providers have a term of approximately 10 years.

The Company's twelve Russian cellular companies have licenses which expire between 2005 and 2007. One of the companies initially received an operating license in 1994, six companies initially received an operating license in 1995 and five companies initially received an operating license in 1996.

Bancomsvyaz holds a license for provision of DCS-1800 mobile services in the Kiev oblast.

COMPETITION

Overview. GTS faces significant competition in virtually all of its existing telecommunications businesses in the CIS. Many of the Company's competitors and potential competitors, which include large multinational telecommunications companies, have substantially greater financial and technical resources than the Company and have the ability to operate independently or with global or local partners and to obtain a dominant position in these markets. The Company believes that it has a competitive advantage in each of these markets because of its operating history, its ability to bundle a broad range of telecommunications services in the region and its ability to make rapid decisions in pursuing new business opportunities and addressing customer service needs. The Company also believes that its local partnerships and reliance on nationals in the management of its businesses and joint ventures provide it with better knowledge of local political and regulatory structures, cultural awareness and access to customers.

International Services. Sovintel faces significant competition from more than ten other existing service providers in Moscow, including Rostelecom and joint ventures between local parties and multinational telecommunications providers. Large competitors include the "Combelga" joint venture, an RPOA operator in which Alcatel and the Belgian PTO participate as foreign investors, "Comstar", a joint venture between GPT Plessey and MGTS, providing services similar to those provided by the Company, TelMos, a joint venture between AT&T, MGTS, Global One, through its Moscow based ventures, and Peterstar, in Petersburg, which is part of the PLD Telekom group. Several smaller companies, such as DirectNet, and Aerocom provide high-volume and carrier's carrier services in Moscow. Bancomsvyaz competes in the switched international traffic market with the Kiev electrosviaz and UTel, a joint venture that includes Western partners with substantial capital and technical resources who together hold a dominant share of the

66

Kiev market. The Company expects that market consolidation will take place among the competitive field in international services.

Domestic Long Distance Services. The Company believes its major competitors in the Russian domestic long distance market consist of Rostelecom, the electrosviazs, including those which are partners in the Company's TeleRoss Ventures, and a variety of ventures that include foreign partners with substantial financial resources. The most significant of such competitors include: Global One, through its regional operations; Rustel, a venture that includes Rostelecom, other Russian partners and International Business Communication Systems, a Massachusetts telecommunications firm; Belcom, a private company in which Comsat has a majority interest and which provides VSAT services primarily to the energy sector; Satcom, a Russian joint venture licensed to provide local, long distance and international service over private and public switched networks; Teleport TP, a satellite overlay company jointly owned by Rostelecom and Petersburg Long Distance that provides satellite teleports in cities throughout Russia; and Comincom, a Russian private venture. In the Russian far east, TeleRoss competes with Vostok Telecom, which is owned by the Japanese companies KDD and NIC and certain Russian partners; and Nakhodka Telecom, which is owned by Cable & Wireless and certain Russian partners.

GTS both cooperates and competes with Rostelecom. Rostelecom provides only international and long distance services to international carriers and regional electrosviazs, and does not provide end-to-end customer services. GTS provides last mile, account management, and transit services for Rostelecom in Moscow, and uses Rostelecom channels and switches for both international and long distance services. GTS provides long distance and international services on an end-to-end basis, using service elements of Rostelecom, the electrosviazs and its own resources. However, Rostelecom does compete with Teleross, in that Teleross provides intercity services to customers, using satellite channels provided by other state agencies (Intersputnik), and provides transit services to various electrosviazs, on a traffic overflow basis.

GTS believes that it enjoys a number of competitive advantages in the Russian domestic long distance market, the most important being the maturity of its international and data service businesses in Russia. This provides GTS with access to the services, customers, products, licenses and facilities of its other businesses. The Company also believes that it has more experienced management, a more comprehensive strategy to build out a nationwide long distance network and stronger relationships with many regional telephone companies and with satellite capacity providers, such as Intersputnik, than most of its competitors. In addition, the Company believes that it does not have any significant competitor in the regional inter-city market (i.e., calls between Russian cities other than Moscow or St. Petersburg).

Data Services. Sovam has several primary competitors in the market for data services: Global One, which began packet-switched service in Moscow and St. Petersburg in June 1992, under the Sprint Networks venture; Demos, an Internet service provider; and Relcom, a cooperative affiliation of computer users that relies on an older generation of technology that supplies slower and lower-cost messaging facilities to customers (primarily domestic commodities traders) that do not require higher levels of service. In addition MCI and Rostelecom have recently announced their agreement to create a national Internet access network utilizing Rostelecom's domestic network and MCI's international infrastructure. Rostelecom has also announced the formation of a new Internet services company called RTK Internet, with Relcom as its partner. Although Sovam's business has grown quickly, the Company believes that Global One is the market leader. GTS believes that other potential competitors, including foreign PSTNs, Infotel, Infocom and Glasnet, are also active in this market.

Although the Company faces significant competition in this market, it believes that it enjoys certain competitive advantages, including the ability to reach a wide area throughout Russia through TeleRoss, innovative service offerings such as Russia On Line, the maturity of its business in the key banking services segment, high levels of customer service and support, and high speed digital channels through TeleRoss.

Local Access Services. The Company believes that its major competition in the Moscow local access market consists of a number of ventures with Western partners, including Telmos (which includes AT&T), Comstar (which includes GPT Plessey), and Combelga. However, since TCM has obtained an allocation of

67

up to 100,000 numbers, the Company believes that TCM will account for a substantial proportion of the new capacity to come onto the market within the next five years.

Cellular Services. Most Russian cellular markets have the potential for three licensed operators, including one operator for each of the GSM and NMT-450 cellular standards, which Russia has adopted as national standards, and one operator using the AMPS cellular standard, which has been set as a regional standard. Many large Western telecommunications operators, including U S WEST, Deutsche Telekom, STET, Midcom and Millicom, have participated in auctions for licenses to provide GSM and NMT-450 cellular service to certain significant Russian urban centers. In addition, a CDMA auction is likely to occur in the future which could result in one or more CDMA operators entering the market. In Ukraine, Bancomsvyaz competes primarily with an NMT operator and a GSM operator in Kiev. Additional GSM licenses were auctioned off in early 1997 and other GSM operators may enter other markets in 1998.

WESTERN EUROPE

OVERVIEW

GTS seeks to position itself as the leading independent carriers' carrier within Western Europe through the development of two ventures, HER and GTS-Monaco Access. HER's objective is to become the leading pan-European carriers' carrier by providing centrally managed cross-border telecommunications transmission capacity to telecommunications companies including traditional PTOs and New Entrants on an approximately 18,000 kilometer high capacity fiber optic network designed to interconnect a majority of the largest Western and Central European cities. HER is currently operating over an approximately 1,700-kilometer portion of the network linking Brussels, Antwerp, Rotterdam, Amsterdam, London and Paris. HER expects the initial five country network to be placed in operation in the second quarter of 1998. This segment of the network is expected to deliver managed transport services over approximately 2,900 kilometers of fiber optic cable linking the cities of London, Rotterdam, Amsterdam, Antwerp, Brussels, Paris, Dusseldorf and Frankfurt. The full 18,000 kilometer network is expected to become fully operational during the year 2000. HER also plans to lease capacity on a transatlantic cable linking the European network with North America and is exploring various interconnectivity options to Russia and Asia. Such intercontinental interconnectivity will help HER satisfy the needs of its European customers with respect to outgoing traffic and attract additional non-European customers with traffic terminating in Europe. HER commenced commercial service over the Brussels-Amsterdam portion of the network in late 1996, and the London-Paris portion in November 1997. GTS-Monaco Access operates an international gateway in Monaco in partnership with, and utilizing the existing gateway infrastructure of, the Principality of Monaco and provides transit and routing of international calls to other telecommunications operators. Through its HER and GTS-Monaco Access ventures, GTS is building a new network for transporting voice, data and multimedia/image traffic for other carriers throughout Western and Central Europe and for worldwide international voice, data and multimedia/image traffic that either originates or terminates in, or transits through, Western and Central Europe.

The Company believes that the international segment of the Western and Central European telecommunications market will be an attractive market for new telecommunications entrants because of its large size, the high operating costs and low productivity of current providers, and the barriers to entry created by the need to control a network and its rights-of-way.

The European telecommunications market has historically been dominated by monopoly PTOs. This system has ensured the development of broad access to telecommunications services in Europe, but it has also restricted the growth of high quality and competitively priced pan-European voice and data services. The current liberalization occurring in Europe is intended to address these structural deficiencies by breaking down PTO monopolies, allowing new telecommunications operators to enter the market and increasing the competition within the European telecommunications market. In March 1996, the European Commission adopted a directive (the "Full Competition Directive") requiring the full liberalization of all telecommunications services in most EU member states by January 1, 1998. The Company expects that full liberalization in these European countries will lead to the emergence of New Entrants with new and competitive service offerings. HER expects this increase in competition will result in lower prices and a substantial increase in the volume of traffic and range of telecommunication services provided. HER believes that as a result of the increased call volume and growth in value added services, participants in these markets will require significant amounts of new cross-border telecommunications transport capacity to provide their services.

The Hermes network will offer PTOs and New Entrants an attractive alternative for the transport of cross-border European telecommunications traffic. In the traditional system, PTOs own and control circuits only within their national borders, and as a result, cross-border traffic must be passed from one PTO to another PTO at the national boundary. No single PTO therefore owns or controls end-to-end circuits for cross-border calls. The alternative for carriers of this traffic will be to build their own transport capacity or use International Private Leased Circuits ("IPLCs") which are provisioned by combining half-circuits on the networks of two or more PTOs. The Company believes that there are a number of problems with these options that result in HER being well-positioned to become the leading independent carriers' carrier in Western and Central Europe. In particular, building their own transport capacity is unlikely to be an attractive option for most

69

carriers because of the high traffic volumes required to justify the expense, the need to focus resources on marketing and customer service, the time commitment and the regulatory and administrative complexities involved, particularly in obtaining the rights of way across national borders. Likewise, IPLCs provided by the PTOs also have a number of disadvantages, including high prices, lack of end-to-end quality control, lack of redundancy, low quality due to diversity of network systems and equipment, limited availability of bandwidth and long lead times for provisioning.

HER

HER's objective is to become the leading pan-European carriers' carrier by providing centrally managed cross-border telecommunications transmission capacity to telecommunications companies including PTOs and New Entrants. HER intends to offer these target customers a better transport system than is currently available in Europe with a higher and more consistent level of transmission quality, redundancy, network functionality and service across Europe at lower prices. Development of the HER network is dependent upon, among other things, HER's continuing ability to obtain the necessary financing, rights-of-way, licenses and other regulatory approvals in a timely and cost-effective manner. See "Risk Factors -- HER Network Roll-out."

HER is developing an approximately 18,000 kilometer, pan-European high capacity fiber optic network designed to interconnect a majority of the largest Western and Central European cities. Each access point of the network will be placed in operation as it is linked to the network. HER intends to build the network using the most accessible and cost-efficient infrastructure base in each of the regions served, including using rights-of-way and existing infrastructure of railways, motorways, pipeline companies, waterways and power companies. HER plans a flexible approach to the network build-out plan and intends to fine-tune the scope, route and design of the network based upon the evaluation of customer demand.

HER began initial trials of the Brussels-Amsterdam portion of the network in the third quarter of 1996 and commenced commercial service in November 1996. Commercial service connecting Paris to Amsterdam, Brussels and London started in November 1997.

HER expects to continue to roll-out full telecommunications transport service on the initial network in the first five countries linking the additional cities of Dusseldorf and Frankfurt in the second quarter of 1998. This initial network in the first five countries is expected to consist of 2,900 kilometers of fiber optic cable covering countries which, in 1995, originated over 60% of all outgoing calls and terminated over 60% of all incoming calls in the countries to be served by the full network. Network coverage is planned to be expanded to include Munich, Berlin, Geneva, Zurich, Stockholm, Copenhagen, and Milan in the third quarter of 1998. By the year 2000, the 18,000 kilometer HER network is expected to have points of presence in at least 32 cities in 15 European countries, including Southern and Central Europe. HER also plans to lease capacity on a transatlantic cable linking the European network with North America and is exploring various interconnectivity options to Russia and Asia.

HER has entered into agreements for the construction and/or lease of fiber optic routes for the initial network in the first five countries. Contracts have been concluded with respect to the portion of the network connecting Germany with each of France, the Netherlands and Switzerland and HER continues to negotiate rights-of-way and other infrastructure arrangements in five other Western European countries representing the remainder of the Western European portion of the rollout. HER will need to negotiate similar agreements to complete the network in four Central European countries. Buildout of the HER network is subject to numerous risks and uncertainties that could delay deployment or increase the costs of the network, or make the network commercially unfeasible. See "Risk Factors -- HER Network Roll-out."

HER was formed on July 6, 1993 by HIT Rail. HIT Rail was incorporated in 1990 by eleven national railways to carry out telecommunications engineering activities in order to construct and exploit a data communications network for railway traffic. GTS-Hermes purchased a 34.4% interest in HER in 1994 and has increased its interest to 50% in 1995 and to 79% in 1997. GTS-Hermes is a wholly owned subsidiary of GTS.

70

Business and Marketing Strategy

The overall strategy of HER is to offer PTOs and New Entrants pan-European cross-border telecommunications transport services to help them, in turn, more successfully meet the needs of their end-user customers. The HER network also provides a vehicle through which a carrier can compete in markets where it does not own infrastructure. HER expects to enter the market ahead of similar competition and encourage a wide variety of carriers to use its network with service offerings that meet their needs. HER's primary service offerings are large-capacity circuits for "wholesale" customers such as PTOs and New Entrants. HER's focus on carriers is designed to complement and not compete with carriers' own business objectives in providing services to end-users.

To establish HER as the leading carriers' carrier for international telecommunications within Europe, HER intends to offer its customers significantly higher quality transmission and extended/advanced network capabilities at a competitive price by focusing on the following:

High Capacity International Network Facilities. The HER network is designed to offer its customers access to high capacity network facilities outside their domestic markets, providing cross-border capabilities without requiring customers to invest in network infrastructure or being constrained by a narrow range of capacity offerings. With STM-64 technology and Wavelength Division Multiplexing ("WDM") upgrades, HER's fiber deployment plan provides for the equivalent of 128 fiber pairs of capacity across Europe.

Uniform Network Architecture. The HER network is designed to offer managed transport services from country to country and across multiple countries utilizing a single uniform network, in contrast to services currently available that use multiple providers over several networks with varying technologies and each under the control of separate, not necessarily compatible, network control systems. The HER network's uniform technology enhances service by providing quality and reliability as well as uniformity of features throughout the network.

Diverse Routing. The HER network architecture includes diverse, redundant routes that are designed to provide high levels of reliability. The network is designed to provide availability of over 99.98% for most routes and to provide customers with a wide range of telecommunications transmission capacity. To achieve this level of reliability without the use of a network similar to the HER network, HER believes that carrier customers would need to purchase additional dedicated circuits to provide for redundancy.

Rapid Provisioning. HER services provide access to the network, such that additional capacity can be provided to customers on the HER network on a rapid basis. This access provides a level of capabilities that HER believes is unavailable in Europe today. This ability to rapidly provide service is largely due to HER's development of capacity substantially in excess of HER's forecasted requirements.

- Flexibility. HER services are focused on providing customers flexibility across the network through which the customer may minimize risk by enabling network rerouting, eventually even under customer direct control.

- Advanced Technology. HER is deploying SDH technology which, by using WDM techniques and hardware, is upgradeable and will permit significant expansion of transmission capacity without increasing the number of fiber pairs in the network. This technology also provides the basis for structuring advanced operating features, such as virtual private network service and ATM-based services. Additionally, the SDH technology deployed by HER may be upgraded.

- Innovative Pricing. Currently the price of E1 equivalent circuits on transborder European routes is artificially high and not necessarily related to the cost of such circuits. HER intends to offer competitive pricing. HER will also offer highly tailored contract terms and volume discounts, which allow carrier customers to plan more efficiently the fixed costs of their service portfolio. Customers can select varying capacity, access, guaranteed availability and contract terms at competitive prices. Customers sourcing from PTOs are generally limited to order from a very narrow set of capabilities offered under inflexible pricing plans.

71

Although HER and GTS have relationships with certain PTOs or other access providers for specific projects, they do not have wide-ranging alliances with any of the major consortia or large Western telecommunications companies. Additionally, HER's strategy calls for it to focus on carriers' carrier services, so that it will limit overlap of target markets with its carrier customers in end user markets. HER believes that this independence will make it an attractive service provider for carriers who may otherwise be reluctant to obtain services from other providers of intra-European transport that also may be their competitors in the retail market.

SERVICES

HER's primary service is large capacity cross-border European circuits provided to carriers and service providers over an integrated, managed pan-European network structure thus providing a service for wholesale customers such as PTOs and New Entrants. The HER network will be based on SDH technology, which provides for digital transmission capability upon which a broad range of advanced functionality may be built and which offers network availability, flexibility, bandwidth speeds and error performance not otherwise available to carriers for transport of telecommunications traffic across national borders in Western and Central Europe. The network is designed to provide customers with a wide variety of bandwidth speeds, ranging from VC12/E1 Standard (equivalent to
2.048 Mbps) to STM-1/E4 Standard (equivalent to 155 Mbps) and beyond.

HER will provide high quality cross-border transmission services for licensed or otherwise authorized telecommunications providers. Services are based on the principle of adding greater value than currently available in the market while retaining competitive prices.

Point-to-Point Transport Service. The current market for cross-border transport is served by IPLCs provided by PTOs. IPLCs are formed by combining half-circuits from two PTOs between customer locations, often with additional PTOs providing transit segments. Under the IPLC service, overall service quality guarantees generally are not provided and only a limited range of bandwidth is available, usually only E1 and in certain instances, E3. The Company believes that HER's Point-to-Point Transport Service will be a major improvement to the PTO-based approach because it provides a greater range of bandwidths (from 2 Mbps (E1 or VC-12) to 140/155 Mbps (E4 or VC-4)) and allows customers to choose a service level agreement with guarantees appropriate for their applications, including guarantees for on-time service delivery and service availability.

Point-to-Point Transport Service consists of two services, "Integrated" and "Node-to-Node." The HER "Integrated" service provides an end-to-end service between customer-specified locations where the customer can request for HER to arrange for "last mile" services from the HER node location to the customer's location. The HER "Node-to-Node" service can be selected when the customer prefers to provides its own services to reach the local HER node location. In Node-to-Node Service, HER guarantees service only on its portion of the network between HER nodes. Both services are competitively priced relative to current service offerings. A premium is charged for the highest guaranteed level of service which incorporates an end-to-end, fully diverse, protected, "Integrated" service. The customer can choose flexible contract terms from one to five or more years' duration, with volume discount schemes designed to ensure that HER remains a cost-effective solution.

Virtual Infrastructure Service. Carriers and operators that plan to expand their operations to become pan-European service providers as the European marketplace is liberalized require a flexible and cost-effective means of telecommunications transport. To date such service providers obtain international transport service by leasing IPLCs. Leasing IPLCs requires a carrier to lease channels on a segment-by-segment basis from multiple PTOs, linking the target cities under arrangements having fixed capacity and pricing structure for each segment of the carrier's network. Leasing IPLCs has several disadvantages, including (i) difficulty in obtaining discount/volume pricing schemes since there is no single provider of pan-European coverage, (ii) delays in implementation due to numerous contractual negotiations and having to interconnect numerous IPLCs, (iii) limited availability of pan-European leased capacity at high bandwidth and (iv) variability of quality due to multiple operators and the absence of a single uniform network. Operators could also construct

72

their own network, which is expensive, time-consuming and complex and which may not be justified by such operators' traffic volume.

HER's Virtual Infrastructure Service will offer a new solution and an attractive alternative to leasing IPLCs or building infrastructure. This service will enable HER's customers to obtain a uniform pan-European or cross-border network under one service agreement by allowing the customer to select any number of cities along the HER network at a pricing structure based on the overall amount of leased capacity for the customer's entire network. The key feature behind Virtual Infrastructure Service is that it gives the customer the ability to add or reconfigure capacity in 24 hours between locations connected in the Virtual Infrastructure Service, thereby enabling the customers to respond almost immediately to changes in traffic. By being able to transfer capacity among the network routes, HER's customers are able to avoid over- and under-utilization of leased channels. This service offering provides a customer with the benefits of ownership (rapid provisioning, freedom to rearrange and control) with a "pay-as-you-go" managed service offering, without the burdens of up-front investment and costs required to build a network, and without having to manage the on-going maintenance and operation of the network.

The service would be delivered through pre-installed physical facilities at each of the customer locations. These facilities are designed to ensure that most growth or changes in customer requirements can be addressed purely by remote logical reconfiguration from the HER Network Operations Center. This remote network management ability is inherent in SDH technology and allows rapid provisioning and high quality of service.

Ring Service. Most medium to large carriers and operators purchase network capacity in excess of actual requirements, and prefer to have physical configuration control over their networks. The HER Ring Service connects multiple customer locations with multiple VC-4 paths in a ring configuration. The customer has direct control over the configuration of the VC-3 and VC-12 paths within the ring, and has exclusive control over the routing. Additional ring capacity can be added with no service interruption and additional customer locations may be added to the ring with minimal service interruption. Because HER is not required to configure 'idle' bandwidth or to manage the 'SDH subnet' this service can be provided at a very competitive rate vis-a-vis other point-to-point services.

Sales and marketing of HER's services are conducted through its sales and marketing department, which includes a director and senior sales managers responsible for various regions and customer segments. Additionally, HER expects that its railway shareholders that develop domestic telecommunications businesses, or other local network access providers, can provide an effective distribution channel to smaller carrier customers.

PRICING

Currently the price of cross-border pan-European calls are often significantly higher than the underlying cost of transport and terminating such calls and higher than the price of intra-country calls or transborder calls to and from liberalized markets. The low cost of operating the network enables HER to attractively and competitively price services in the face of declining overall tariffs for telecommunication services. HER's low-cost basis is due to, among other things, its use of up-to-date technology without the burden of legacy networks, which requires fewer employees to operate.

The term of a typical customer agreement currently ranges from 1 to 3 years. The customer agrees to purchase, and HER agrees to provide, cross-border transmission services. In general the customer agrees to pay certain non-recurring charges and recurring charges on an annual basis, payable in twelve monthly installments. If the customer terminates the service order prior to the end of the contract term, it is generally required to pay HER a cancellation charge equal to three months service for each of the twelve months remaining in the contract term. HER guarantees transmission services to a certain service level. If such levels are not met or HER fails to deliver service by the committed delivery date, the customer is eligible for a credit against charges otherwise payable in respect of the relevant link.

73

CUSTOMERS

HER's high capacity, SDH-based fiber optic network is designed to enable PTOs and New Entrants to integrate high quality, cross-border capacity into their end user offerings. As of November 30, 1997, fifteen customers were under contract for service on the HER network, including PTOs, a global consortium of PTOs, Internet service providers, an international carrier, VANs and resellers. HER provided capacity of approximately 110 E1 equivalent circuits as of November 30, 1997. The type and quality of HER's customers validates the concept of the HER network, and illustrates the type of customers who will be attracted to the full network. The success of this limited network also demonstrates the demand for cross-border transport services. In total, HER is targeting seven major market segments or customer groups which can be characterized as follows:

- Existing PTOs. This customer segment consists of the traditional European PTOs that generally participate in the standard bilateral agreements for cross-border connectivity. Hermes provides a vehicle for PTOs to compete in non-domestic markets both before and after January 1, 1998. As of January 1, 1998, both reserved and non-reserved traffic can be transported by alternative infrastructure providers, thus vastly expanding the available PTO market for HER.

- Global Consortia of Telecommunications Operators. Many of the largest PTOs and international carriers have pooled resources and formed consortia in order to compete more effectively in important telecommunications markets such as those in Western Europe particularly outside their home markets. Prior to liberalization of the provision of switched voice services in Western European markets, one of the primary objectives of these consortia is to provide non-reserved pan-European services to multinational business customers, including X.25/frame relay (high speed data network) service and closed-user group voice services. Under the current regulatory framework, consortia would otherwise be required to purchase leased lines at negotiated retail rates, even within their home countries. HER believes that it provides an attractive alternative at better pricing in those environments where such a consortium does not already own its infrastructure. Furthermore, HER believes that it is well positioned to provide cross-border connectivity between different domestic infrastructures of these alliances.

- International Carriers. This customer segment consists of non-European carriers with traffic between European and other international gateways. Such carriers include Teleglobe, GTS-Monaco Access and eventually the U.S. Regional Bell Operating Companies. HER can provide these customers a pan-European distribution network to gather and deliver traffic to and from their own and other hubs.

- Alternative Carriers. This segment consists of second carriers, cable TV and mobile carriers and competitive access providers. These new carriers have chosen to compete with the incumbent PTOs in their respective countries, and the Company believes that they would look favorably to an alternative such as HER. HER believes that this segment will sustain the largest growth as competition emerges in Europe. HER also believes that non-PTO competitors in Europe will prefer to use a non-PTO alternative like HER to meet their cross-border telecommunication transport needs.

- Internet Backbone Networks. Internet backbone networks are a fast emerging segment and are expected to generate significant requirements for the services HER offers. These require large capacity international connectivity services between Internet nodes
(point of interconnection between local Internet service providers) in all local European markets. The Internet segment is experiencing significant growth in demand for transmission capacity.

- Resellers. Resellers are carriers that do not own transmission facilities, but obtain communications services from another carrier for resale to the public. Resellers are also a growing segment of the market and are expected to increase in conjunction with the liberalization of the European telecommunications market. In the U.S., for example, resellers were a significant factor in the expansion of competition.

74

- Value Added Networks ("VANs") and other Service Providers. VANs are data communications systems in which special service features enhance the basic data transmission facilities offered to customers. Many of these networks are targeted to the data transfer requirements of specific international customer segments such as airlines and financial institutions. VANs' basic network transmission requirement is to connect data switches or processors. VANs currently purchase their own international circuits and build additional resiliency into their network infrastructure. HER will allow them to meet these needs cost-effectively, and to extend their services to new markets or customers without substantial capital investment.

HER expects that additional demand for alternative service providers will come from increased usage of dedicated circuits for Internet access, private lines for the deployment of wide-area networks by large corporations, "single source" local and long distance services by small and medium-sized businesses and emerging broad band applications such as cable TV programming distribution (other than broadcast) to the end user.

CURRENT OPERATIONS

HER currently operates an approximately 1,700 kilometer network connecting the cities of Brussels, Antwerp, Rotterdam, Amsterdam, London and Paris. HER began initial trials of a 244 kilometer portion of the network between Brussels and Amsterdam in the third quarter of 1996 and commenced commercial service in November 1996. Commercial service connecting Paris to Amsterdam, Brussels and London started in November 1997. HER's Network Operations Center located in Brussels, Belgium and its backup center located in Antwerp, Belgium are fully operational and house network management and customer support services which operate 24 hours a day, seven days a week. Billing and customer service functions are also operational.

NETWORK DESIGN

Network Architecture. The network architecture is based on a highly meshed flat topology which covers a wide geographical area with large distances between individual network nodes. This architecture allows rerouting of traffic at electronic speeds in the event of a network failure. This approach also lowers network cost by allowing each node to be sized to match anticipated traffic volumes rather than to a standard capacity. Individual nodes can be configured to connect any trunk to any other in the nodes, thus allowing efficient transmission of traffic. Each node will be connected to at least two other nodes allowing rerouting of traffic in the event of a network failure. HER believes that its network will be the first cross border pan-European network with such redundancy.

The HER network has been designed to be controlled by a single network management center and supported by advanced operational support systems. A centralized network center can pinpoint overloaded pathways or malfunctioning circuitry and reroute traffic much more quickly than networks controlled by separate network centers operated by PTOs in different countries. HER primarily uses Alcatel for the supply of transmission equipment and network management systems. HER's advanced operational support systems allow it to correct network failures and isolate equipment faults with greater speed and at a lower cost than is the case with heterogeneous multi-operator networks. Critical elements of the network, including network maintenance and control systems, are designed with redundancy in order to ensure a high quality of service. The network design has several important resilience features including: multiple paths to each node, built-in hardware redundancy and redundant power supplies. For all network routings, there will be at least two paths. Should service failure occur on one route, the network is designed to automatically re-route traffic to another route. HER believes that these techniques will result in performance of 99.98 percent or better for premium service customers for most routes.

HER expects to operate the entire network and to own substantially all of the network equipment as well as some segments of the fiber optic cable. A substantial part of the fiber is leased on a long-term basis. Long-term leases for fiber are advantageous to HER because they reduce the capital expense burden of building large quantities of capacity before they can be used. Where HER leases dark fiber, the infrastructure provider

75

will generally be responsible for maintaining such fiber optic cable. HER will enter into agreements with Alcatel and infrastructure providers and other third parties to supply and/or maintain the equipment for the HER network. See "Risk Factors -- HER Network Roll-out."

Network Capacity. The network will consist of Synchronous Digital Hierarchy ("SDH") STM-16 links managed by equipment and operating centers owned by HER and running on dark fiber leased from infrastructure providers or built by HER on leased rights of way. Each line system and multiplexer works initially at the 2.5 Gbps (STM-16) level. The most important types of equipment used or to be used in this network are Add-Drop Multiplexors ("ADMs") and regulators and a variety of optical amplifiers for boosting optical signals. The STM-16 links are expected, where needed, to be upgraded to STM-64. Furthermore, fibers will be multiplexed using WDM, also as required. Additional capacity can be achieved by adding new fiber accesses to a given city over alternative routes, thereby achieving more meshing and the resulting improved network availability.

Network Agreements. HER has entered into agreements and letters of intent with various infrastructure providers for construction and/or dark fiber lease of portions of the HER network. HER's agreements for leases of portions of the network typically required the infrastructure provider to provide a certain number of pairs of dark fiber and node and/or regenerator sites along the network route commencing on certain dates provided by HER. The term of a lease agreement typically ranges from 10 to 18 years. An agreement typically contains optical specification standards for the fiber and methods of testing. HER is allowed to use the cable for the transmission of messages and in other ways, including increasing capacity. The infrastructure provider also provides space for the location of equipment and spare parts and guarantees the provision of power and other utilities together with environmental controls and security to ensure the proper functioning of the equipment. The infrastructure provider is typically responsible for maintenance of the cable and the provision of first line maintenance to equipment and permits HER access to such facilities. Access arrangements to the nodes are also provided so that connection may be made to HER customers or to the rest of the network. An agreement also provides for an annual price for the provision of fiber and for the facilities and maintenance. The agreements typically provide for termination by the parties only for material breach, with a 90 day minimum cure period. The agreements typically contain a transition period after termination of the agreement to allow HER to continue to serve its customers until it can reach agreement with an alternative infrastructure provider.

Local Access. Access to the HER network will be provided to clients through SDH access lines including at the STM-1 or STM-4 level. However, customers who continue to use the older PDH technology may also access the HER network. In each city, as a HER point of presence is deployed, HER may contract with a local access network supplier for "last mile" services to customer locations. HER will not invest in building local access infrastructure but such connectivity can be supplied on a case-by-case basis via preferred local access partner arrangements. Currently Telfort in the Netherlands and Belgacom in Belgium are providing local access to the operating Amsterdam-Brussels route. In London and Paris, HER has contracted with local access providers to connect the HER network to intra-city networks in those cities. Pursuant to this agreement, HER can offer its carrier customers local connectivity in those cities. Various Local Access Network Suppliers may also be interested in HER for the purpose of linking the business centers in which they are active. Therefore, the

76

Company believes that the relationships between HER and local access network suppliers can benefit both parties. Set forth below is an illustration of the connection between the HER network and local access providers.

HER is currently operating on an approximately 1,700 kilometer portion of the network. Under HER's current plan, HER expects to have an aggregate of approximately 3,200 kilometers completed in the first half of 1998, approximately 10,200 kilometers completed at the end of 1998 and the entire 18,000 kilometer network completed by the year 2000. Hermes also plans to lease capacity on a transatlantic cable linking the European network with North America in 1999.

The Dusseldorf-Amsterdam, Frankfurt-Dusseldorf and Paris-Frankfurt fiber optic routes are currently under construction. "Under construction" means that with respect to each of the segments that make up each of these routes, one of the following is occurring: (i) HER has contracted to build or is contracting to build the

77

fiber optic cable segment, and (ii) HER has leased or will lease such segment of dark fiber optic cable from a third party who has built or is currently building such segment. The dates set forth above may be subject to delays due to a variety of factors, many of which are beyond the control of the Company. See "Risk Factors -- HER Network Roll-Out."

HER is deploying the network along the rights-of-way of several shareholders as well as the rights-of-way of a variety of alternative sources, including motorways, waterways, pipelines and utilities. The rights-of-way of HER-built portions of the network will be provided pursuant to long-term leases or other arrangements entered into with railroads, highway commissions, pipeline owners, utilities or others. HER generally prefers to use the infrastructure of its rail-based shareholders when such infrastructure is available on a timely and commercially reasonable basis. In certain cases, however, HER has not been able to reach agreement with such shareholders for the provision of rights-of-way along their railways, which has resulted in significant delays to the network buildout. In all cases, it is the policy of HER to evaluate multiple alternative infrastructure suppliers in order to maximize flexibility. As a result of its network development activities to date, HER has gained access to infrastructure for its network routes which, in certain cases, HER believes will be difficult for its competitors to duplicate.

Competition

The European and international telecommunications industries are competitive. HER's success depends upon its ability to compete with a variety of other telecommunications providers offering or seeking to offer cross-border services, including (i) the respective PTO in each country in which HER operates and (ii) global alliances among some of the world's largest telecommunications carriers. HER expects that some of these potential competitors may also become its customers. HER believes that the ongoing liberalization of the European telecommunications market will attract New Entrants to the market and increase the intensity of competition. Competitors in the market compete primarily on the basis of price and quality. HER intends to focus on these factors and on service innovation as well. HER business plan anticipates substantial head-to-head competition as well as indirect competition.

WorldCom recently announced plans to construct a pan-European fiber network, the first phase of which is expected to connect London, Amsterdam, Frankfurt, Brussels and Paris by early 1998. Although the Company believes that the proposed WorldCom pan-European network is primarily intended to carry WorldCom traffic, WorldCom has stated that any excess capacity on such network will be used to provide a competitive carrier's carrier service.

HER also competes with respect to its "point-to-point" transborder service offering against circuits currently provided by PTOs through International Private Leased Circuits. In addition, the liberalization of the European telecommunications market is likely to attract additional entrants to both the "point-to-point" and other telecommunications markets.

If HER's competitors, many of whom possess greater technical, financial and other resources than HER, devote significant resources to the provision of pan-European, cross-border telecommunications transport services to carriers, such action could have a material adverse effect on HER's business, financial condition and results of operations. There can be no assurance that HER will be able to compete successfully against such new or existing competitors. See "Risk Factors -- Competition."

HER RECAPITALIZATION

HER has completed a recapitalization (the "HER Recapitalization"), wherein HER extended rights to subscribe to additional shares of HER to GTS-Hermes, HIT Rail and the eleven railways comprising the HIT Rail consortium. Pursuant thereto, GTS-Hermes and two of the eleven railways that comprise the HIT Rail consortium have exercised their subscription rights, while HIT Rail and the other nine railways have declined to exercise their subscription rights. HER has issued (i) 150,592 shares to GTS-Hermes in exchange for the conversion of loans and additional consideration, (ii) 24,007 shares to HIT Rail in exchange for the conversion of loans, (iii) 11,424 shares to Societe Nationale des Chemins de Fer Belges S.A. de Droit Public/Nationale Maatschappij der Belgische Spoorwegen N.V. Van Publiek Recht (the Belgian national railway)

78

("SNCB/NMBS") and (iv) 4,365 shares to AB Swed Carrier (a wholly owned subsidiary of SJ, the Swedish national railway). As a result, GTS-Hermes owns 79.08%, HIT Rail owns approximately 12.63%, SNCB/NMBS owns 6% and AB Swed Carrier owns 2.29% of the issued HER shares. Pursuant to the HER Recapitalization, HER, GTS-Hermes, HIT Rail, SNCB/NMBS and AB Swed Carrier have executed a new Shareholders Agreement, the principal terms of which are set forth below.

Under the new Shareholders Agreement, actions to be taken by shareholders will be adopted by a simple majority vote with the exception of certain actions which will require at least 85% of the votes cast: (i) purchase by HER of its own shares and any redemption thereof, (ii) exclusion of preemptive rights in the case of the issuance of new shares and the transfer of shares held by HER, except in the event of a public listing of the shares or of new shares or of an offering of shares or options on new shares (warrants) to professional investors in order to obtain further funding, (iii) winding up or dissolution of HER, (iv) any amendment to the articles of association other than those pertaining to increases in the authorized capital of HER or to convert HER into an N.V. ("Naamloze Vennootschap") to enable a public listing of shares or new shares,
(v) any amendment to the scope of HER's business, (vi) the declaration of dividends and (vii) the admission of new shareholders to the Shareholders Agreement. In addition, the Shareholders Agreement provides that (a) if GTS-Hermes is the owner of at least 50% of the issued shares, then it will have the right to make a binding nomination for the appointment of half of the members of the Board of Supervisory Directors or (b) if GTS-Hermes is the owner of at least two-thirds of the issued shares, then it will have the right to make a binding nomination for the appointment of half of the members of the Board of Supervisory Directors plus one member more, appointed pursuant to nominations by all other shareholders. As long as HIT Rail is the owner of at least one share, HIT Rail will be entitled to make a binding nomination for the appointment of at least one member of the Supervisory Board. The Shareholders Agreement also provides that shareholders who participated in the capital restructuring other than GTS-Hermes and HIT Rail with a shareholding of at least 6.8% subject to adjustment in the discretion of the other shareholders will be entitled to make a binding nomination for the appointment of one member of the Board of Supervisory Directors. Shareholders who participated in the capital restructuring other than GTS-Hermes and HIT Rail who hold fewer than 6.8% of the issued share capital of HER will be entitled on a rotating basis to make one binding nomination for the appointment of a member of the Board of Supervisory Directors for two-year periods.

Articles of Association and Shareholders Agreement

Under the Articles of Association and the Shareholders Agreement, both GTS-Hermes and HIT Rail have preemptive rights in connection with issuances of ordinary shares and options on shares to be issued in proportion to the total nominal value of the shares held by each of them. Preemptive rights can be exercised for four weeks after the date the notice of the offer is received by the shareholders.

The Shareholders Agreement provides that HER or its designated vendor will provide fiber capacity in its network for use by the shareholders of HER on fair commercial terms, use, quantity and price to be negotiated on a bilateral basis. In the Shareholders Agreement, HIT Rail has covenanted to (i) use its best efforts to establish such commercial agreements between individual HIT Rail shareholders and HER, to obtain rights of way from individual HIT Rail shareholders and to cooperate in obtaining such licenses as may advance the business of HER, (ii) use its best efforts to ensure that the HIT Rail shareholders cooperate in obtaining such license in accordance with the business plan of HER and as may be necessary or advisable in furtherance of HER's business, (iii) will not, so long as both HIT Rail and GTS-Hermes are shareholders of HER and for one year after HIT Rail ceases to be a shareholder, agree with any entity other than GTS-Hermes or HER to assist or cooperate in the development of any pan-European telecommunications operator and (iv) use its best efforts to obtain on HER's behalf such materials as may be required and arrange inspection visits of selected rights of way for the purpose of making initial cost estimates.

The foregoing summary of the Shareholders Agreement does not purport to be complete and is qualified in its entirety by reference to the Shareholders Agreement.

LICENSES AND REGULATORY ISSUES

A summary discussion of the regulatory framework in the countries of the network in the first five countries and the next five countries into which HER expects to develop the network is set forth below. This discussion is intended to provide a general outline, rather than a comprehensive discussion, of the more relevant regulations and current regulatory posture of the various jurisdictions.

National authorities in individual member states of the EU are responsible for regulating the operation (and in some cases the construction) of telecommunications infrastructure. HER believes that the adoption of the Full Competition Directive and the various related Directives adopted by the European Parliament and the Council of the EU have resulted in the removal of most regulatory barriers to the operation of telecommunications infrastructure in the countries of the initial network in the first five countries.

HER requires licenses, authorizations or registrations in all countries to operate the network. There can be no assurance that HER will be able to obtain such licenses, authorizations or registrations or that HER's operations will not become subject to other regulatory, authorization or registration requirements in the countries in which it plans to operate. Licenses, authorizations or registrations have been obtained in the United Kingdom, the Netherlands, Belgium, France and Germany and a trial concession has been granted in Switzerland. HER intends to file applications in other countries in anticipation of service launch in accordance with the network roll-out plan.

On June 28, 1990, the European Commission, in an effort to promote competition and efficiency in the European Union, issued a directive (the "1990 Directive") requiring EU member states to immediately liberalize all telecommunication services with the exception of voice telephony to the general public (basic voice services provided over the public switched voice network). This step liberalized value added services and voice services over corporate networks and/or "closed user groups," although the exact definitions of the terms used in the 1990 Directive were not altogether clear.

On July 22, 1993, the Council of EU agreed that all voice telephony services in EU member states should be liberalized by January 1, 1998 subject to additional transitional periods of up to five years to allow member states with less developed networks to achieve the necessary adjustments. It was agreed that such exemptions would be granted to Spain, Ireland, Greece and Portugal, subject to formal application and satisfaction of certain requirements. Luxembourg, because of the small size of its market, would be eligible for a special transitional period of up to two years.

In April 1995, a communication from the European Commission sought to clarify the types of services that were liberalized by the 1990 Directive, stating that the burden of proof as to why a service should be considered "reserved" and therefore not open to competition should be upon the PTOs and the regulatory authorities of member states. Along with this statement came the threat of formal procedures under the Treaty of Rome against member states that do not implement the 1990 Directive "within a reasonable time." Procedures have been brought so far against Italy, Greece, Germany and Spain for failing to apply the requirements of the 1990 Directive.

On March 13, 1996, the European Commission adopted the Full Competition Directive extending the 1990 Directive to all services, requiring that licensing procedures for these services be transparent and non-discriminatory, requiring member states to fully liberalize alternative infrastructure to allow a competitive market for "non-reserved" services such as data, value added services and non-public (closed-user group) switched voice services by July 1, 1996 and mandating open competition in all public telecommunications services, including voice telephony to the general public, by January 1, 1998 (except for countries to which grace periods were granted in accordance with the 1993 Council Resolution).

On April 10, 1997, the European Parliament and the Council of Ministers adopted a Directive on a common framework for general authorizations and individual licenses in the field of telecommunications services, including networks. Licenses must be awarded through open, non-discriminatory and transparent procedures and applications will be required to be dealt with in a timely fashion. The number of licenses may only be restricted to the extent required to ensure the efficient use of radio frequencies or for the time necessary to make available sufficient numbers in accordance with EC law.

80

HER believes that many European countries have revised telecommunications regulations to comply with the 1990 Directive and the Full Competition Directive and that such changes will enhance HER's ability to obtain other necessary regulatory approvals for its operations.

As a multinational telecommunications company, HER is subject to varying degrees of regulation in each of the jurisdictions in which it provides its services. Local laws and regulations and the interpretation of such laws and regulations, differ significantly among the jurisdictions in which HER operates. There can be no assurance that future regulatory, judicial and legislative changes will not have a material adverse effect on HER, that domestic or international regulators or third parties will not raise material issues with regard to HER's compliance or noncompliance with applicable regulations or that regulatory activities will not have a material adverse effect on HER. See "Risk Factors -- Government Regulation." The regulatory framework in certain jurisdictions in which HER provides its services is briefly described below.

United Kingdom

Since the elimination in 1991 of the United Kingdom telecommunications duopoly consisting of British Telecommunications and Mercury, it has been the stated goal of Oftel, the United Kingdom telecommunications regulatory authority, to create a competitive marketplace from which detailed regulation could eventually be withdrawn. The United Kingdom has already liberalized its market beyond the requirements of the Full Competition Directive, and most restrictions on competition have been removed in practice as well as in law. HER has received a license from the Secretary of State for Trade and Industry which grants it the right to run a telecommunications system or systems in the United Kingdom connected to an overseas telecommunications system and to provide international services over such systems. Like the licenses granted to other providers of international facilities-based services, the license granted to HER on December 18, 1996 was for an initial six months' duration and thereafter is subject to revocation on one month's notice in writing. The short duration of these initial licenses was adopted for administrative convenience on the opening-up of the United Kingdom market for international facilities-based services. The Department of Trade and Industry ("DTI") has confirmed that it intends to replace the initial licenses with new licenses and that it would not normally expect to revoke an initial license without replacing it with another license giving an equivalent authorization. The DTI is currently discussing with license holders the arrangements to put these new licenses into effect and although the DTI has indicated that the new licenses are expected to be of 25 years duration, there can be no certainty that this will be the case or that the new licenses will not contain terms or conditions unfavorable to HER.

The Netherlands

On July 1, 1997 the Dutch government abolished the prohibition on the use of fixed infrastructure for the provision of public voice telephony, thereby complying with the requirements of the Full Competition Directive six months ahead of schedule. On August 1, 1996, HER was granted a license for the installation, maintenance and use of a fixed telecommunications infrastructure.

An entirely new Telecommunications Bill was introduced to the Second Chamber (the House of Representatives) of the Parliament on September 15, 1997. The new Telecommunications Act is intended to confirm the full liberalization of the telecommunications market according to European Community standards. It is not expected that the new Telecommunications Act will detrimentally affect the conduct of business by HER.

Belgium

Belgium has implemented the "alternative infrastructure" provider provision of the Full Competition Directive. Full liberalization of competition, including the provision of voice telephony, requires further legislation which is expected to be introduced to the legislature in the near future. HER has obtained, through a wholly-owned subsidiary, a license from the Belgian regulatory authority to provide liberalized services using alternative infrastructure and is currently operating under its license in Belgium on the Brussels-Amsterdam

81

route. HER also has authorization to build infrastructure between major Belgian population centers and the relevant border crossings.

Germany

Germany has approved legislation to implement the Full Competition Directive and remove all remaining restrictions on competition from January 1998. HER was granted a license by the German regulatory authorities on July 18, 1997. The license permits HER to operate the portions of the network in Germany connecting Dusseldorf, Frankfurt and Stuttgart; Dusseldorf to the Dutch border; and Stuttgart to the French and Swiss borders. HER expects to extend its license in Germany as appropriate in order to enable it to operate the remaining portions of the network in Germany.

France

A new regulatory agency, the Autorite de Regulation des Telecommunications ("ART"), was established in France effective January 1, 1997. In 1996, France approved legislation to implement the Full Competition Directive and to remove all remaining restrictions on competition from January 1998. HER applied for an authorization to operate its network in specific regions of France, which was approved on October 22, 1997.

Switzerland

The Swiss Parliament has recently passed a new Telecommunications Law which will enter into force on January 1, 1998. Although Switzerland is not a Member State of the EU, the effect of the law is largely to mirror the EC telecommunications liberalization Directives and therefore from that date existing voice telephony monopoly will be abolished and such services will be fully liberalized. An independent national regulatory authority has previously been established. HER obtained a trial concession on October 30, 1997, in order to roll out its network and to provide its services in advance of the full liberalization coming into effect on January 1, 1998.

Italy

Although in the past Italy has been dilatory in implementing EC liberalization measures, Italy enacted legislation on July 31, 1997 which substantially completes the liberalization of services in accordance with the Full Competition Directive. The Parliament has also approved the creation of an independent national regulatory authority for the telecommunications and audiovisual sectors. The most recent EC liberalization Directives relating to licensing and interconnection remain to be implemented. HER intends to apply for a license to provide its services in due course.

Spain

Under the Full Competition Directive Spain was granted the right to request a delay of up to five years in liberalizing fully its telecommunications market. However, the Spanish government and the European Commission have agreed that full liberalization should take place on December 1, 1998. In order to ensure effective liberalization from that date, the Commission Decision granting the eleven month extension sets out a timetable of interim measures leading up to full liberalization. These measures include the passing of legislation authorizing regional cable operators to provide telecommunications services and the adoption of a new General Telecommunications Bill effectively transposing EC Directives into Spanish law. Further RETEVISION, S.A. has been granted a second national operator's license to compete with the national PTO and Spain has agreed to grant a third national operator license in early 1998. HER intends to apply for a license to provide its services in due course.

Sweden

Full liberalization of the Swedish telecommunications market occurred in 1993. A new Telecommunications Act was passed this year to reinforce the powers of the national regulatory authority, to ensure

82

conformity with EC Directives and to supplement the pre-existing licensing regime with a general authorization regime for services other than telephony services, mobile services and leased lines. HER intends to register to provide its services in due course.

Denmark

With the liberalization of infrastructure from July 1, 1997 Denmark has fully liberalized its telecommunications markets in accordance with the requirements of the relevant EC Directives. An independent national regulatory authority has been established. According to the Danish rules, HER will not require any regulatory approval in order to install or operate the network in Denmark.

GTS-MONACO ACCESS

GTS owns a 50% interest in and manages GTS-Monaco Access, a joint venture with the Principality of Monaco created to develop Monaco's existing international telecommunications infrastructure into a leading international gateway hub for transport of international traffic to European and overseas destinations. The Principality has constructed and operates a sophisticated international gateway infrastructure that includes an international digital switching center and a satellite earth station to support significant amounts of carriers' carrier traffic. Through Monaco's network, GTS-Monaco Access is linked to approximately 170 countries worldwide. GTS believes that this partnership provides it with the opportunity to build a strong international gateway operator in lucrative Western European markets.

GTS-Monaco Access offers competitively priced international switching and transit services, primarily to the "wholesale" international gateway and carrier-to-carrier portion of the international calling market, as distinguished from "retail" services offered to end users. Basic service offerings include (i) international switched traffic; (ii) international private lines; (iii) facilities management, including billing, customer management and fault reduction systems; (iv) resale distribution for Internet service providers; and
(v) prepaid calling card platform services.

With the cooperation of Monaco Telecom ("MT"), GTS-Monaco Access is entitled to exercise the privileges of signatories to international treaties such as the ITU, and to international satellite agreements, such as Intelsat, Inmarsat and Eutelsat. Other signatories are generally PTOs and other quasi-governmental telecommunications entities. GTS-Monaco Access purchases capacity on international fiber routes at rates available only to recognized operators which are substantially below the rates charged to other service providers. These fiber-based facilities are an important element for GTS-Monaco Access's core network and provide it with capacity that may be leased or resold to customers. Monaco inaugurated its independent country code, 377, on June 21, 1996, which made it eligible for certain privileges, including special terms (generally reserved for PTOs) in connection with transmission agreements, transit agreements, settlements and low-cost accounting rates with select carriers.

GTS's partner in GTS-Monaco Access is an investment fund designated by the Principality of Monaco to represent its interests. GTS-Monaco Access functions in cooperation with MT under a commercial agreement governing, among other things, the terms of use of existing facilities, access to and acquisition of new international infrastructure, and sales and marketing. GTS exercises operational control of the joint venture, and provides managerial and financial support, international telecommunications expertise and strategic planning. Neither GTS nor its partner is obligated to fund operations or capital expenditures of GTS-Monaco Access. Losses and profits of GTS-Monaco Access are allocated to the partners in accordance with their ownership percentages, in consideration of funds at risk. As of September 30, 1997, GTS and its partner had each made equity contributions of $1.7 million to GTS-Monaco Access. In addition, GTS-Monaco Access had outstanding loans of $2.9 million to GTS as of September 30, 1997. See "Management's Discussion and Analysis -- Accounting Methodology -- Profit and Loss Accounting." The agreement between GTS-Monaco Access and MT, by its terms, continues in operation until 2020.

BUSINESS AND MARKETING STRATEGY

GTS's objective is to develop GTS-Monaco Access into a leading international gateway hub. The Company's strategy to achieve this objective includes the following:

- Develop Advanced Carrier Services Offerings. GTS-Monaco Access intends to develop its "advanced carrier services" offerings to include global 0800 services and international free phone services, which GTS believes will broaden customer relationships, enhance revenues and help to protect it from price-based competition.

- Develop Relationships to Broaden Service Offerings. GTS-Monaco Access has begun to develop relationships to broaden its service offerings. GTS-Monaco Access has entered into agreements with UUNET, one of its gateway customers, to provide wholesale Internet access to GTS-Monaco Access's carrier customers in a number of Western European countries. The agreement allows these services to be "cobranded" with GTS's affiliates.

- Pricing. Price is a critical factor in the market for international switching as competition increases due to expanding international capacity, advances in technology and falling regulatory barriers. GTS- Monaco Access intends to price its services competitively with the prevailing price for comparable inter-PTO transit and gateway services. GTS-Monaco Access is not bound by legacy systems, infrastructure and personnel levels and can, therefore, manage lower cost operations.

- Leverage Non-Aligned Position. Because GTS's Western European activities are not allied with any of the major consortia or large Western European telecommunications companies, and generally focus on carriers' carrier services, GTS-Monaco Access will not compete with its carrier customers in retail markets. This independence should make GTS-Monaco Access an attractive service provider for Western European carriers who may otherwise be reluctant to obtain services from the larger operators of international gateways that are often their competitors in the retail market.

- Exploit GTS Synergies. GTS intends to support GTS-Monaco Access by allying it with other GTS companies in Europe and the CIS. GTS-Monaco Access is expected to realize significant reductions in its cost structure through access to low-cost pan-European transmission capacity through alternative infrastructure providers such as HER, Sovintel and C-Datacom International, Inc., GTS's Indian venture, already route international traffic through GTS-Monaco Access's gateway.

- Local Points of Presence. Beginning in the first quarter of 1998, GTS-Monaco Access intends to establish points of presence in the United Kingdom, France and Germany in order to take advantage of the HER network rollout and negotiate arrangements with local customers and suppliers for the pick up and delivery of international traffic.

CUSTOMERS

Targeted customers for GTS-Monaco Access include:

- Non-Aligned PTOs. GTS believes that various large American and Western European PTOs that lack adequate international switching and transport facilities of their own can be persuaded to purchase international services from GTS-Monaco Access, rather than from competing PTOs or consortia.

- Mobile Carriers. GTS believes that some of the non-PTO mobile carriers, which currently provide only a small percentage of Western European mobile telecommunications traffic, will prefer the "independent" international gateway service offerings of GTS-Monaco Access to those of their PTO competitors.

- Internet Service Providers. Growth in Internet usage creates a significant opportunity for a nonaligned Internet access provider such as GTS-Monaco Access, since many Internet service providers will be in direct competition with PTO-owned services in large European markets.

- Second Carriers/Resellers. GTS believes that many second carriers will seek to enter new markets quickly without investing in international switching capacity.

84

- Established ("Aligned") PTOs. This customer segment will be a niche market for GTS-Monaco Access. As markets are deregulated and carriers become increasingly competitive, traditional friendly correspondent relations may become strained, and opportunities may emerge to leverage GTS's non-aligned status to route traffic between rivals or to displace incumbents for transit relationships.

- Other GTS Companies. GTS-Monaco Access currently provides gateway services to Sovintel, CDI and other GTS companies that aggregate traffic or provide international long distance services. It may also provide these services to HER.

NETWORK

GTS has enhanced MT's existing technology platform of digital switching, fiber optic transmission, satellite and submarine cable facilities by interconnecting this existing network infrastructure to multiple terrestrial routes covering Europe and to undersea fiber optic cables connecting the GTS-Monaco Access network to Asia and the Americas.

The network infrastructure of GTS-Monaco Access is complementary with that of HER, with each serving the carriers' carrier market from different perspectives; HER for bandwidth services and GTS-Monaco Access for switched call terminations and other carrier services. Beginning in the first quarter of 1998, GTS-Monaco Access intends to establish points of presence in Europe by co-locating in certain cities served by HER, which will allow GTS-Monaco Access to terminate traffic through HER and reduce GTS-Monaco Access's transmission costs.

LICENSES AND REGULATORY ISSUES

Because it operates in coordination with MT, the licensed operator of the Monaco public network, and in indirect partnership with the government, GTS-Monaco Access's telecommunications activities in Monaco require no telecommunications license.

Because the Principality of Monaco is not an EU member state, GTS-Monaco Access's telecommunications activities in the Principality are not subject to European law. However, GTS-Monaco Access will have to comply with EU regulation to the extent it does business in EU member states. The regulatory requirements established by the EU create general guidelines under which the national agencies of EU member states regulate. Accordingly, local laws and regulations may differ significantly among these jurisdictions, and the interpretation and enforcement of such laws and regulations may vary. Local rules are sometimes based on the informal views of the local ministries which, in some cases, are subject to influence by the local PTOs. In certain of the Company's existing and target markets, there are laws and regulations which affect the number and types of customers which the Company can address. For instance, certain countries may and do require licenses for communication companies to interconnect to the public network to originate traffic.

In addition, one of the services provided by GTS-Monaco Access is a form of transit service, known in the industry as "re-filing." Re-filing is the practice of routing traffic through a third country in order to take advantage of disparities in settlement rates between different countries, allowing traffic to a potential country to be treated as if it originated in the third country that enjoys lower settlement rates with the destination country, thereby resulting in lower overall costs on an end-to-end basis. Re-filing is prevalent in the industry even though the practice is technically in contravention of ITU regulations. In practice, because of the widespread non-observance of these regulations, such a contravention normally does not give rise to specific legal problems. However, their enforceability essentially depends on the status given to ITU obligations by Member countries' domestic laws. Accordingly, there can be no assurance that GTS-Monaco Access's re-filing services might not be disrupted or be the subject of legal process at some time in the future. In such event, within the EU a defense may be available that the ITU regulations are anti-competitive and contravene the Treaty of Rome, although there can be no certainty that such a defense would succeed.

COMPETITION

GTS-Monaco Access faces competition from consortia of telecommunications operators, large PTOs and other international telephone operators with advanced network infrastructures, access to large quantities of

85

long-haul capacity and established customer bases. PTOs currently providing large amounts of international traffic have already established direct routes, transit arrangements and correspondent relations and many have excess capacity that they resell in competition with GTS-Monaco Access.

GTS expects that GTS-Monaco Access will be able to compete effectively in certain identified market segments because most of its targeted customers are in new and fast growing markets and have not established long-term relationships with international gateway providers, and because it has equal access to advanced infrastructure and international fiber routes, potential access to low cost transport from HER and an "independent" status that allows it to service a worldwide range of potential customers.

CENTRAL EUROPE

In Central Europe, GTS's objective is to become one of the leading alternative telecommunications providers in the region. GTS currently provides private data communications services to government and commercial customers in Hungary and the Czech Republic. In the Czech Republic, the Company provides outgoing voice services and operates an international gateway and a data services network. In Hungary, GTS operates a VSAT network which GTS believes is the largest VSAT network in Central Europe as measured by number of VSAT sites. The Company has also signed an agreement to provide international data services in Poland, subject to receipt of necessary governmental approvals. GTS's strategy is to expand its service offerings as the regulatory environment permits, leveraging its existing VSAT and international gateway infrastructure where possible and providing a broad range of services to its target markets.

Hungary

GTS-Hungary. GTS-Hungary, a 99% owned subsidiary of GTS, is a leading provider of customized data services offering high quality, reliable virtual private network services to customers throughout Hungary and, through other GTS affiliates, other countries in Central Europe. GTS-Hungary provides these services through VSATs installed at customer sites throughout the country and a microwave-based high speed overlay network for points in the Budapest metropolitan area. Along with these data transmission services, GTS-Hungary provides high quality customer service including (i) significant system integration support in the initial implementation of the customers' networks and in on-going expansion and improvements and (ii) a unique maintenance and technical support service, which include "rapid response" service calls and 24-hour hub service operations support, which can be backed by financial guarantees when required.

As of September 30, 1997, GTS-Hungary's VSAT network consisted of approximately 935 owned and operated VSAT sites which the Company believes makes it the largest VSAT-based network in Central Europe. GTS believes that its choice of VSAT technology as a way of quickly deploying a full range of business services nationwide will allow it to capture key customers and market segments. Such positioning, the Company believes, will enable GTS-Hungary to expand its service offerings as the Central European market matures and as regulatory authorities further privatize and deregulate the telecommunications industry. GTS-Hungary is undertaking a nationwide expansion of its microwave-based Budapest overlay network. The expansion will increase GTS-Hungary's revenue base in the region and provide opportunities to leverage further its other service offerings. There can be no assurance, however, that the expansion will be completed on a timely and commercially feasible basis.

The Hungarian state lottery is GTS-Hungary's largest customer, accounting for more than 54% of GTS-Hungary's VSAT revenue for the nine months ended September 30, 1997. GTS-Hungary has also targeted its VSAT network services to business customers in the domestic service industry and other government organizations. Although GTS-Hungary continues to diversify its revenue and customer base, the loss of the Hungarian state lottery as a customer would have a material adverse effect on GTS-Hungary's business.

GTS-Hungary generally charges its data services customers a flat monthly fee for a fixed amount of usage and usage-based fees for use above the contractual amount. Customers are billed in Hungarian forints (indexed to US dollars) on a monthly basis. Pricing is generally determined for an individual client based

86

upon the size of traffic requirements. In general, GTS-Hungary's strategy is to minimize the initial customer investment in order to lower the barriers to purchase, while committing customers to long-term contracts.

GTS-Hungary's major competitors include BankNet, Hungaro-DigiTel and MATAV, the Hungarian PTO, each of which operates a network with at least 200 VSAT sites. MATAV offers a broad range of services and has recently targeted the business sector that GTS serves. GTS believes that, while some of its competitors have stronger financial resources, GTS-Hungary remains the leading VSAT service provider in Hungary in terms of number of VSAT sites, the size and quality of its infrastructure and the quality of its service. GTS also believes it has distinguished itself from its competition by its superior customer service.

Currently, all VSAT licenses in Hungary have been granted under temporary telecommunications regulations. The temporary licenses prohibit connection to public telecommunications networks or other international or domestic data-transmitting systems. In December 1993, GTS received a temporary service permit to provide data-transfer services utilizing a VSAT-based wireless communications system throughout Hungary. In March 1997 the government issued new telecommunications regulations which require all operations with temporary licenses to apply for permanent licenses by the end of April 1997. GTS-Hungary has submitted applications for the conversion of its temporary licenses to permanent ones. While no assurances can be given, GTS expects permanent licenses to be issued in due course. The failure to receive such licenses would have a material adverse effect on the business of GTS-Hungary.

Neither GTS nor its partner in GTS-Hungary are obligated to fund operations or capital expenditures of GTS-Hungary. Losses and profits of GTS-Hungary are allocated to the partners in accordance with their ownership percentages, in consideration of funds at risk. As of September 30, 1997, GTS had made equity contributions of $9.5 million to GTS-Hungary, GTS' partner has not made any equity contributions as of September 30, 1997. In addition, GTS-Hungary had outstanding loans of $3.4 million to GTS as of September 30, 1997. See "Management's Discussion and Analysis -- Accounting Methodology -- Profit and Loss Accounting." Further, the joint venture does not have an expiration date.

EuroHivo. In addition to its network and data services, GTS also provides nationwide paging services primarily to the retail consumer market through its 70% owned joint venture, EuroHivo. GTS has concluded that EuroHivo is not a core business and is currently assessing offers to sell its interests in EuroHivo. In connection with this anticipated divestiture, the Company wrote-off its investment in EuroHivo in the third quarter of 1997. See "Management's Discussion and Analysis -- Results of Operations -- Consolidated Ventures."

Czech Republic

The Czech Companies. The Czech Companies, which consist of two wholly owned subsidiaries of GTS, offer the only alternative international telephony service in the Czech Republic, as well as a full range of private data services, delivered through a combination of a fully digital microwave overlay network and an international satellite gateway in Prague and GTS-Hungary's VSAT network. Through an intercompany arrangement with GTS-Hungary, the Czech Companies provide all of the same VSAT services offered by GTS-Hungary. In addition, the Czech Companies offer high-speed Internet access service and are among the leading Internet access providers in the Czech Republic. The Czech Companies seek to become the second carrier in the Czech Republic and are also targeting opportunities in Slovakia, based upon the historic relationship between the Czech and Slovak markets.

The Czech Companies network consist of an earth station linked to GTS-Monaco Access and to British Telecom, a series of point-to-point and point-to-multipoint microwave connections providing dedicated access to the buildings served by the Czech Companies and individual VSATs based on, and controlled by, GTS-Hungary's hub in Budapest.

The Czech Companies target customers include real estate developers, hotels and multinational companies which require international voice or data services or Internet connectivity, where both GTS's own services and the services of GTS partners are sold. The Czech Companies provide outgoing international voice services and high-speed Internet access to large commercial buildings in Prague. As of September 30, 1997,

87

the Czech Companies had concluded agreements with building owners to convert PABXs in 23 buildings in Prague. International voice services are offered at prices similar to those of the Czech PTO. The Czech market for VSAT services is extremely competitive, with prices at approximately 50% of those in Hungary for basic services. The Czech Companies plan to pursue customers who require value-added services which may be offered at higher prices and better margins.

The Czech Companies are licensed to provide international satellite and domestic private voice and data services. They received their operating licenses in 1994 and 1995 and began offering services in 1995. The licenses grant permission to install and operate up to 150 earth stations and, upon application, an additional 150 earth stations. The licenses currently prohibit the provision of switched voice services and the interconnection to public voice, telex and data networks and telecommunications networks of other providers.

The Czech Companies are the only alternative international telephony provider licensed in the Czech Republic. As such, their only competitor is SPT Telecom, the Czech PTO. Should SPT decide to compete aggressively with the Czech Companies, it has the ability to discount prices below those which could be easily sustained by the Czech Companies. In data services, Telenor, GITY and Nextel (a subsidiary of SPT Telecom) are the Czech Companies' three major competitors for data services in the Czech Republic. GTS believes that its experience in establishing VSAT services in the region and its emphasis on integrated voice and data services provides the Czech Companies with a competitive advantage. Additionally, GTS's transmission facilities and infrastructure in Hungary and Monaco provide them with a relatively low cost infrastructure and, as a consequence, greater pricing flexibility than their competitors. With respect to Internet services, GTS believes that, although this market consists of a large number of small providers and that SPT Telecom will seek to enter this market, the dedicated, high-speed infrastructure that the Czech Companies are installing will provide superior services to its customers.

ASIA

Chinese law generally prohibits foreign investment or participation in the operation of telecommunications services, while Indian law requires foreign telecommunications operators to conduct certain telecommunications businesses, including basic switched telephony and cellular services, through joint ventures that are at least 51% owned by Indian partners. GTS believes that these restrictive regulations will eventually be liberalized and that its early entry into these markets and its strong relationships with influential commercial firms and with local, regional and national-level government entities will provide it with a strong competitive advantage over competitors that await more explicit regulatory regimes authorizing direct telecommunications investments.

China

GTS participates in the nationwide tourist industry VSAT network through GTS China Investments LLC, a company in which GTS holds a 75% interest and an affiliate of the Soros Foundations owns a 25% interest. See "Certain Related Party Transactions." GTS China Investments LLC holds an indirect 63% interest in Beijing Tianmu Satellite Communications Technology Co. Ltd. ("Beijing Tianmu"), which provides technical, operational and financial support for the VSAT network. In addition, through Shanghai V-Tech Telecommunications Systems Co., Ltd. ("V-Tech"), a venture in which GTS holds a 75% interest, the Company provides financing, operational consulting, technical and engineering services to a Shanghai-based VSAT network operator.

With respect to V-Tech, in addition to the Company's initial equity contribution of $3.75 million, GTS committed to fund up to an additional $3.0 million (all of which has been funded as of September 30, 1997). The joint venture expires in April 2015, and profits and losses are allocated according to ownership interests in consideration of funds at risk. See "Management's Discussion and Analysis -- Accounting Methodology -- Profit and Loss Accounting."

With respect to Beijing Tianmu, in addition to the Company's initial equity contribution of $8.75 million, GTS is responsible for arranging additional financing of up to $14.4 million, subject to the approval of the venture's Board of Directors, the majority of members of which are elected by GTS. The joint venture expires

88

in March 2021, and profits and losses are allocated according to ownership interests, in consideration of funds at risk. See "Management's Discussion and Analysis -- Accounting Methodology -- Profit and Loss Accounting."

India

In India, GTS is following the strategy it implemented in Moscow and is currently pursuing in Central Europe, in which it initially penetrates the telecommunications market by developing satellite-based international gateway networks to provide telecommunications services to targeted business customers. GTS's operations in India are conducted through C-Datacom International, Inc. ("CDI"), a wholly owned subsidiary which provides digital international private line communications to and from India for multiple applications, including data and voice. While not permitted to provide telephony services, CDI is currently in the process of installing an international gateway switch adjacent to GTS-Monaco Access's international gateway for the purpose of handling international traffic.

EMPLOYEES

On September 30, 1997, GTS employed a total of 166 persons. On September 30, 1997, the joint ventures in which GTS participates employed approximately 1,400 persons. The Company believes its future success will depend on its continued ability to attract and retain highly skilled and qualified employees. The Company believes that its relations with its employees are good.

Although GTS's employees are not unionized, unions represent employees of the Company's railroad partners in HER. Under the agreements contemplated between HER and its railroad partners, some of these employees will be required to construct and maintain certain portions of the HER network. There can be no assurances that unionized employees of HER's partners will not experience labor unrest.

PROPERTIES

The Company's physical properties include owned and leased space for offices, storage and equipment rooms and collocation sites. Additional equipment rooms will be leased as networks are expanded. GTS maintains regional headquarters offices in Moscow and Budapest, as well as facilities in McLean, Virginia and London. Hermes is headquartered just outside of Brussels, Belgium.

LITIGATION

In addition to routine legal proceedings incidental to the conduct of its business, the Company, GTS-Hungaro and GTS-Hungary are named as defendants in an action captioned USH Ventures and USH Telecom, L.L.C. v. Global TeleSystems Group, Inc. and GTS-Hungaro, Inc., Civil Action No. 97C-08-86, commenced in August 1997, which is currently pending in the Superior Court of the State of Delaware in and for New Castle County. The complaint alleges breach of contract and interference with a business relationship. While it is not possible at this time to make a meaningful assessment of the outcome of this litigation, based upon information currently available and upon consultation with counsel, the Company does not believe that the outcome of this litigation will have a material adverse effect upon the financial condition of the Company.

See "-- Global TeleSystems Group, Inc. Non-Employee Directors' Stock Option Plan."

93

GLOBAL TELESYSTEMS GROUP, INC. NON-EMPLOYEE DIRECTORS' STOCK OPTION PLAN

The purpose of the Global TeleSystems Group, Inc. Non-Employee Directors' Stock Option Plan (the "Directors' Plan") is to permit eligible non-employee directors of GTS (each a "Non-Employee Director") to share in the growth of the value of GTS through the grant and exercise of nonqualified stock options.

The total number of shares of Common Stock presently reserved and available for delivery under the Directors' Plan is 375,000, subject to adjustment upon certain changes in capitalization. Upon completion of the Offerings, an additional 900,000 shares of Common Stock, totalling 1,275,000 shares, will be reserved and available under the Directors' Plan. The Directors' Plan is administered by the compensation committee of the Board of Directors (the "Committee"). Only directors of GTS who are not employees of GTS or any subsidiary of GTS on the date on which an option is to be granted are eligible to participate in the Directors' Plan on such date.

An option (a "Directors' Option") to purchase shares of Common Stock was granted to each Non-Employee Director on the effective date of the Directors' Plan and a Director's Option is granted to each new Non-Employee Director when he or she is first elected or appointed to serve as a director of GTS. One-half of the Directors' Options vests six months after the date of grant. An additional one quarter become exercisable on the date six months following the first annual meeting of GTS's shareholders to occur after such date of grant, and the remaining one quarter shares become exercisable on the date six months following the second annual meeting of GTS's shareholders to occur after such date of grant. Prior to the completion of the Offerings, initial Directors' Options represented 18,000 shares of Common Stock. After the completion of the Offerings, an initial Directors' Option will represent 22,250 shares of Common Stock. On the date of the third annual meeting of GTS's shareholders following the grant of the initial Directors' Options to any Non-Employee Director, provided that such Non-Employee Director remains an incumbent on such date, an additional Directors' Option to purchase 13,500 shares of Common Stock is granted to such Non-Employee Director. The second Directors' Options become exercisable with respect to 4,500 shares on the date six months after the date of grant, with respect to an additional 4,500 shares on the date six months following the first annual meeting of GTS's shareholders to occur after such date of grant, and with respect to the final 4,500 shares on the date six months following the second annual meeting of GTS's shareholders to occur after such date of grant. After the completion of the Offerings, on the date of each annual meeting of GTS's shareholders, an additional Directors' Option to purchase 9,000 shares will be granted each year on the date of the Company's annual meeting to the individuals who will serve as elected Non-employee Directors of the Company during the next year.

Directors' Options are nonqualified stock options which are subject to certain terms and conditions including those summarized below. The exercise price per share of Common Stock purchasable under a Directors' Option will be equal to 100% of the fair market value of Common Stock on the date of grant. Each Directors' Option will expire upon the earliest of (a) the tenth anniversary of the date of grant, (b) one year after the Non-Employee Director ceases to serve as a director of GTS due to death or disability, (except that, in the case of disability, if the Non-Employee Director dies within that one-year period, the Directors' Option is exercisable for a period of one year from the date of death), (c) three months after the Non-Employee Director ceases to serve as a director of GTS for any reason other than death or disability, (except that, if the Non-Employee Director dies within that three-month period, his or her Directors' Options are exercisable for a period of one year from the date of such death), and (d) three months after the Non-Employee Director ceases to be employed by GTS if such Non-Employee Director had become an employee of GTS (except that, if the Non-Employee Director dies within that three-month period, his or her Directors' Options are exercisable for a period of one year from the date of such death). Each Directors' Option may be exercised in whole or in part by giving written notice of exercise to GTS specifying the Directors' Option to be exercised and the number of shares to be purchased. Such notice must be accompanied by payment in full of the exercise price in cash or by surrender of shares of Common Stock or a combination thereof. Directors' Options granted under the Directors' Plan may not be sold, pledged, assigned or otherwise disposed of in any manner other than by will or by the laws of descent and distribution.

94

At the time of grant, the Board of Directors may provide in connection with any grant made under the Directors' Plan that the shares of Common Stock received as a result of such grant are subject to a right of first refusal by GTS.

The Board of Directors may amend, alter, suspend, discontinue or terminate the Directors' Plan at any time, except that any such action will be subject to the approval of GTS shareholders at the next annual meeting following such Board of Directors' action if such shareholder approval is required by any federal or state law or regulation or the rules of any stock exchange or automated quotation system on which Common Stock may then be listed or quoted, or if the Board of Directors determines in its discretion to seek such shareholder approval.

THE GTS 401(k) PLAN

The GTS 401(k) Plan (the "401(k) Plan") is a defined contribution retirement benefit plan that is qualified for favorable tax treatment under
Section 401 of the Code. All employees of GTS, including the Named Executive Officers, who are at least 21 years of age and have completed the minimum service requirement are eligible to participate in the 401(k) Plan. The 401(k) Plan participants may defer pre-tax income by contributing to the plan up to the maximum amount permitted by law. After-tax contributions are also permitted under the 401(k) Plan. GTS matches 50% of each participant's pre-tax contribution to the 401(k) Plan up to 5% of the participant's total compensation. In addition, GTS may, in its sole discretion and in a nondiscriminatory manner, contribute additional amounts as profit sharing to each participant's account. The amounts that are deposited into each participant's account are invested among various investment options according to the direction of the participant. Each participant's pre-tax and after-tax contributions are immediately vested and nonforfeitable. GTS's matching contribution and profit sharing allocations to each participant's account do not vest until the participant has completed three years of service with GTS, at which time the matching contribution and profit sharing allocations become 100% vested. Each participant is eligible to begin receiving benefits under the
401(k) Plan on the first day of the month coincident with or following the attainment of normal retirement age. There is no provision for early retirement benefits under the 401(k) Plan.

THE SFMT, INC. EQUITY COMPENSATION PLAN

The purpose of the SFMT, Inc. Equity Compensation Plan (the "Equity Compensation Plan") is to attract, retain and motivate key employees, officers and eligible independent contractors of GTS and to enable such individuals to own Common Stock and to have a mutuality of interest with other shareholders of GTS through the grant of restricted stock and other equity-based awards.

The total number of shares of Common Stock that may be issued or transferred under the Equity Compensation Plan is four percent of the total number of shares of Common Stock outstanding at the beginning of the calendar year, subject to certain adjustments, which are described below. This threshold number may be increased by the number of shares (a) that were issued under the Equity Compensation Plan with respect to which no dividends were paid and (b) that were subsequently forfeited, in accordance with the terms of the Equity Compensation Plan.

The Equity Compensation Plan is administered by the Committee. The chief executive officer of GTS has the authority to recommend the individuals to whom awards will be granted, subject to approval by the Committee. The Committee has full and binding authority to determine the fair market value of the Common Stock and the number of shares included in any awards, to establish terms and conditions of any award, to interpret the Equity Compensation Plan, to prescribe rules relating to the Equity Compensation Plan and to make all other determinations necessary to administer the Equity Compensation Plan. The Committee may condition the vesting of restricted stock upon the attainment of specified performance goals or such other factors as the Committee may determine in its sole discretion. In the event that the Committee determines, in its sole discretion, that an award of restricted stock would not be appropriate with respect to any individual who has been recommended for an award by the chief executive officer, the Committee has the authority to grant to any such individual any other variety of equity-based compensation award, including, but not limited to, phantom stock, phantom units, stock appreciation rights, performance shares and performance units. The Committee does not, however, have the authority to grant stock options pursuant to the Equity Compensation Plan.

Grants under the Equity Compensation Plan are determined by the Committee in its sole discretion. For this reason, it is not possible to determine the benefits or amounts that will be received by any individual employee or group of employees in the future. The Equity Compensation Plan will remain effective until November 14, 2004, unless earlier terminated by GTS. No restricted stock may be granted under the Equity Compensation Plan on or after November 14, 2000.

During a specified period set by the Committee commencing with the date of any restricted stock award, the participant is not permitted to sell, transfer, pledge or otherwise encumber shares of restricted stock.

97

Within these limits, the Committee, in its sole discretion, may provide for the lapse of such restrictions or may accelerate or waive such restrictions in whole or in part, based on service, performance and such other factors. Unless the Committee specifically determines otherwise, a restricted stock award granted under the Equity Compensation Plan vests one-third on the second anniversary of the date of grant, one-third on the third anniversary of the date of grant and one-third on the fourth anniversary of the date of grant.

The Committee may impose such other restrictions on shares of Common Stock issued under the Equity Compensation Plan, including a right of first refusal by GTS that requires the participant to offer GTS any shares that the participant wishes to sell.

The Equity Compensation Plan provides that, in the event of a change to the Common Stock (whether by reason of merger, consolidation, reorganization, recapitalization, stock dividend, stock split, combination or exchange of shares, or other change in the capital structure made without receipt of consideration), the Board of Directors will preserve the value of outstanding awards by making certain equitable adjustments in its discretion.

The Board of Directors may amend, alter, suspend, discontinue or terminate the Equity Compensation Plan at any time, except that any such action will be subject to the approval of GTS shareholders at the first annual meeting following such action if such shareholder approval is required by any federal or state law or regulation or the rules of any stock exchange or automated quotation system on which Common Stock may then be listed or quoted, or if the Board of Directors determines in its discretion to seek such shareholder approval.

THE AMENDED AND RESTATED 1992 STOCK OPTION PLAN OF GLOBAL TELESYSTEMS GROUP, INC.

In 1992, the Board of Directors approved the adoption of the 1992 Stock Option Plan of Global TeleSystems Group, Inc. (the "1992 Option Plan") for key employees of GTS. The purpose of the 1992 Option Plan is to enable GTS to attract and retain the best personnel for positions of substantial responsibility, to provide additional incentives to employees of GTS and its subsidiaries and to promote the success of the business of GTS and its subsidiaries by providing certain employees with an ownership interest in the Company.

The total number of shares of Common Stock that may be subject to options granted under the 1992 Option Plan (the "1992 Options") is generally 18.5% of the total number of shares of Common Stock outstanding at the beginning of the calendar year.

The 1992 Option Plan is administered by the Committee, which must be composed of not less than two members of the Board of Directors who are "non-employee directors" within the meaning of Rule 16b-3 of the Exchange Act. The Committee has full and binding authority to determine the fair market value of the Common Stock, the exercise price of options to be granted, the persons to whom and the times at which options will be granted and the number of shares to be represented by each option. The Committee also has full and binding authority to interpret the 1992 Option Plan, to prescribe rules relating to the 1992 Option Plan, to establish terms and conditions of each 1992 Option and to make all other determinations necessary to administer the 1992 Option Plan.

The 1992 Option Plan will remain effective until November 14, 2004, unless earlier terminated by GTS. Grants under the 1992 Option Plan are determined by the Committee in its sole discretion. For this reason, it is not possible to determine the benefits or amounts that will be received by any individual employee or group of employees in the future.

The 1992 Option Plan authorizes the grant of both nonqualified options, which are not qualified for special tax treatment, and incentive stock options ("ISOs"), which qualify for special federal income tax treatment under Section 422 of the Code. The exercise price per share of Common Stock issuable pursuant to an ISO may not be less than 100% of the fair market value of Common Stock on the date of grant. Unless otherwise specified in any respective option agreement, a nonqualified 1992 Option will expire ten years and one day after the date of grant and an ISO will expire ten years from the date of grant. Each person granted 1992 Options shall be provided with an option agreement setting forth the terms of each grant pursuant to the

98

1992 Option Plan. Unless the Committee specifically determines otherwise, each 1992 Option vests one-third on each of the first three anniversaries of the date of grant. The full purchase price of the shares must be paid, either in cash, by delivery of previously owned shares, or by withholding of shares having a fair market value equal to the 1992 Option exercise price or by such other method approved by the Committee. Each 1992 Option expires (a) 30 days after the option holder ceases to be an employee of GTS for any reason other than death, disability or retirement, (b) one year from the date of death or disability of an employee, or (c) 90 days following retirement of the employee. 1992 Options may not be sold, pledged, assigned or otherwise disposed of in any manner other than by will or by the laws of descent and distribution.

The Committee may impose such other restrictions on shares of Common Stock issued under the 1992 Option Plan, including a right of first refusal by GTS. In addition, if the amount of any payment under the 1992 Option Plan, either separately or in combination with any other payment by GTS, would constitute an excess parachute payment within the meaning of Section 280G of the Code, the total payments payable under the 1992 Option Plan will be reduced in order to maximize the amount received by the participant under the 1992 Option Plan in combination with other payments by GTS.

The 1992 Option Plan provides that, in the event of a change to the Common Stock (whether by reason of merger, consolidation, reorganization, recapitalization, stock dividend, stock split, combination of shares or exchange of shares, or other change in the capital structure made without receipt of consideration), the Board of Directors will, in its discretion, preserve the value of outstanding 1992 Option Plan awards by making certain equitable adjustments.

The Board of Directors may amend, alter, suspend, discontinue, or terminate the 1992 Option Plan at any time, except that any such action will be subject to the approval of GTS shareholders at the first annual meeting following such Board of Directors action if such shareholder approval is required by any federal or state law or regulation or the rules of any stock exchange or automated quotation system on which Common Stock may then be listed or quoted, or if the Board of Directors determines in its discretion to seek such shareholder approval.

THE GTS 1996 TOP TALENT RETENTION PROGRAM

GTS implemented the GTS 1996 Top Talent Retention Program (the "Program") which, for 1996 only, alters the terms offered to certain employees under the 1992 Option Plan. Employees who are offered participation in the Program must sign a "retention agreement," the terms of which are described below, in order to receive any 1992 Options during 1996. The Program has been offered to approximately 28 employees, and it provides that any 1992 Options granted to such participants will vest as follows: (i) one-half of any 1992 Option granted under the Program will vest at a rate of 25% per year beginning on the first anniversary of the initial date of grant and (ii) the remaining portion of any 1992 Option granted under the Program will vest one-quarter according to the achievement of performance revenue levels, and one-quarter according to the achievement of price levels of Common Stock, provided that all options will vest on the fifth anniversary of the date of grant regardless of whether such performance revenue and pricing levels are attained.

GTS-HERMES, INC. 1994 STOCK OPTION PLAN

The GTS-Hermes, Inc. 1994 Stock Option Plan (the "GTS Hermes Plan") was adopted by the board of directors of GTS-Hermes, Inc. ("GTS-Hermes") in 1994 to enable employees of GTS-Hermes and its subsidiaries, including HER, and affiliates to participate in ownership of GTS-Hermes and to attract and retain key employees of particular merit. The GTS-Hermes Plan provides for the award of incentive stock options, nonqualified stock options and stock appreciation rights. All employees of GTS-Hermes and its subsidiaries, including HER, and affiliates are eligible to participate in the GTS-Hermes Plan.

The maximum number of shares authorized with respect to grants of awards under the GTS-Hermes Plan in each calendar year is 6.5% of the shares of common stock, par value $0.01 per share, of GTS-Hermes issued and outstanding, and the aggregate number of shares of stock subject to the GTS-Hermes Plan is 13% of the total shares of stock issued and outstanding. The GTS-Hermes Plan is administered by a committee appointed by the board of directors of GTS-Hermes, which has broad discretion to determine who shall receive awards under the GTS-Hermes Plan and the characteristics of any award thereunder, including the price, term and vesting of such award, and to interpret the terms of the GTS-Hermes Plan and awards granted under the GTS-Hermes Plan. Stock appreciation rights may not be awarded alone and may only be awarded in tandem with an option grant.

The GTS-Hermes Plan provides that in the event of a change in control, as defined under the GTS-Hermes Plan, any stock appreciation rights outstanding for at least six months and any stock options awarded under the GTS-Hermes Plan not previously exercisable and vested which have been held for at least six months from the date of grant will become fully vested and exercisable at an adjusted price to be determined

100

according to the highest sales price per share paid in any transaction reported or offer made at any time during the preceding 60 days as determined by the committee.

The board of directors of GTS-Hermes may amend, alter or discontinue the GTS-Hermes Plan at any time, provided that the rights of participants are not impaired, except that shareholder approval is necessary for certain material modifications.

HER intends to establish a stock option plan to replace the GTS-Hermes Plan for the purpose of incentivizing HER key employees, in substantially similar form to the GTS-Hermes Plan. The aggregate number of shares of HER stock subject to the proposed plan would be approximately 13% of the total shares of HER stock issued and outstanding including options. Grants under the GTS-Hermes Plan would be converted into grants under the proposed HER plan. Upon establishment of such plan, the GTS-Hermes Plan would be terminated.

(1) Stock options are for GTS-Hermes stock pursuant to the GTS-Hermes Plan. Each stock option vests one-third on each of the first three anniversaries of the date of grant. HER intends to establish a new stock option plan to replace the GTS-Hermes Plan during the fourth quarter of 1997. The new plan, the Key Employee Stock Option Plan of Hermes Europe Railtel B.V. (the "New Plan"), and the stock option agreements that will be issued pursuant thereto have been drafted and are pending final approval and execution. The options outstanding under the GTS-Hermes Plan will be converted into options under the New Plan as soon as practicable after such plan becomes effective.

(2) Due to the high exercise price of the options granted under the GTS-Hermes Plan and the relatively low value of GTS-Hermes shares, GTS and GTS-Hermes have agreed that it is reasonable to set the potential realizable value of the options at zero with respect to the assumed annual rates of stock price appreciation of 5% and 10% for the term of the options.

(3) In 1995, Jan Loeber was granted 3.5 shares.

EMPLOYMENT AGREEMENTS

GTS has executed employment agreements (together, the "Employment Agreements") with all the Named Executive Officers. The agreements with Messrs. Thames, Radzikowski and Marks include a three-year term of employment commencing on April 1, 1996. Mr. Radzikowski resigned from the Company in the second quarter of 1997. The agreements with Mr. Toth and Mr. Loeber include a two-year term of employment commencing on April 1, 1996 and January 3, 1995, respectively. All the Employment Agreements provide for the automatic renewal of the term for additional one-year periods after the initial term unless written notice of intent to terminate is provided by either party within a stated period of between 120 days and six months prior to the renewal date. The salary of each Named Executive Officer is reviewed yearly and may be increased at the sole discretion of the Board of Directors. In addition to salary, each Named Executive Officer is eligible for a performance-based annual bonus, to participate in the GTS 1992 Stock Option Plan (with the exception of Mr. Loeber whose employment agreement provides him with an option grant under the GTS-Hermes Plan), to receive standard health and insurance benefits that are provided to executives of GTS, to receive certain other fringe benefits and to be reimbursed for all reasonable expenditures incurred in the execution of each Named Executive Officer's respective duties. In addition, Mr. Loeber's employment agreement provides him with 20,000 shares of restricted stock that vest in an amount of one-third each year for three years beginning on January 2, 1997.

The performance-related bonuses are discretionary annual bonuses. Mr. Loeber's bonus is based on a comparison of the projected to the actual performance of HER during any given fiscal year. The maximum amount of Mr. Loeber's bonus is a percentage of his salary that is determined by the Board of Directors in its sole discretion. The bonus awards for Messrs. Thames, Marks and Toth are based on the achievement of performance goals by a combination of both GTS and the pertinent named Executive Officer and are determined each year by the compensation committee. The amount of the performance-based bonuses awarded to Messrs. Marks and Toth may equal up to 30% of the executive's salary for the year. Mr. Thames may receive a performance-based bonus of up to 100% of his salary for the year.

Each Employment Agreement may be terminated by GTS by giving notice of intent to not extend the term of employment, for cause or as a result of the Named Executive Officer's permanent disability. In the event that the employment relationship is terminated due to the employee's disability or death or if GTS provides notice of its intent not to renew the term of employment, GTS shall pay to the Named Executive Officer or to the Named Executive Officer's estate, as the case may be, the salary and bonus for the remaining portion of the fiscal year in which the termination of employment occurs. In addition, if the Company provides notice of its intent not to extend the term of employment, each Named Executive Officer will receive assurances in an amount equal to his salary for the greater of (a) the number of months or days in the notice period and (b) the period during which the Named Executive Officer remains subject to the restrictive covenants described below. If the Named Executive Officer is terminated for cause or if he quits other than for the reasons stated above, he shall not be entitled to any salary bonus or severance (other than accrued salary).

Each Employment Agreement includes noncompetition and nonsolicitation clauses that are effective during the term of employment and for a period of from four months to one year thereafter. In addition, the Employment Agreements include an unlimited covenant of confidentiality and nondisclosure. Any dispute arising under an employment agreement must be resolved through arbitration, except that each agreement also provides for specific performance and for a court injunction in the event of a breach by the Named Executive Officer.

CERTAIN RELATED PARTY TRANSACTIONS

Alan B. Slifka, the Chairman of the Board of Directors, owns an interest in an office building in New York in which GTS leased office space until the corporate headquarters were moved to McLean, Virginia on March 1, 1995. GTS retains a small office space in New York City that is leased from Mr. Slifka on a monthly basis, and the annual expense for 1996 was $40,600. Mr. Slifka also has a consulting agreement with GTS pursuant to which he is paid consulting fees of $100,000 per year.

Bernard McFadden, Director, has a consulting agreement with GTS pursuant to which he is paid $100,000 in consulting fees each year.

In August and September 1997, affiliates of George Soros and Mr. Slifka purchased 319,149 and 57,015 shares of Common Stock, respectively, at a price of $15.67 per share in the Company's private stock offering. In addition, affiliates of Mr. Slifka purchased $2.9 million of Convertible Bonds in September 1997. Pursuant to the terms of the indenture related to the Convertible Bonds, the Convertible Bonds will be convertible into such shares of Common Stock as is equal to the principal amount of such Convertible Bonds divided by the applicable conversion price, which conversion price shall be equal to the public offering price of the Common Stock in the Offerings. See "Description of Certain Indebtedness."

Affiliates of Soros Fund Management purchased $40 million of notes from GTS in 1996, which notes bear interest at 10% per annum, in partial consideration of which (i) W. James Peet was appointed to the Board of Directors and (ii) the affiliates received warrants to purchase 4,444,443 shares of Common Stock. Together with their prior equity interests in GTS, these affiliates currently hold, on a fully diluted basis (excluding shares underlying stock options), in excess of 26.6% of the Company's Common Stock. In accordance with the terms of the warrant agreement, the exercise price of the warrants was reduced from $10.27 per share to $9.33 per share as the outstanding debt had not been repaid prior to December 31, 1996. In addition, these affiliates collect a monitoring fee of $40,000 per month, which they will continue to collect until the consummation of the Offerings, at which point it will be reduced to $25,000. Under certain agreements, these affiliates have the right to co-invest with GTS in all of its new ventures throughout Asia, excluding countries in the former Soviet Union, and pursuant to this right, one of these affiliates holds a 25% interest in GTS China Investments LLC. See "Business -- Asia."

Affiliates of Capital Research International purchased $30 million of notes from GTS in 1996, which notes bear interest at 10% per annum, in partial consideration of which it received warrants to purchase 3,333,333 shares of Common Stock. In accordance with the terms of the warrant agreement, the exercise price of the warrants was reduced from $10.27 per share to $9.33 per share as the outstanding debt had not been repaid prior to December 31, 1996.

Jean Salmona, a director of GTS, is the Chairman and Chief Executive Officer of CESIA. CESIA also provides consultancy services for CDI and for HER. The Company paid $123,685 in 1996 and $0 in both 1995 and 1994 to CESIA for consulting services related to CDI. In addition, HER paid $84,270 in 1996 and $0 in both 1995 and 1994 to CESIA for consulting services. Further, the Company paid $2,314 and $5,443 to CESIA in 1996 and 1997, respectively, pursuant to the purchase agreement with CESIA related to the CDI business.

Pursuant to a 1995 purchase agreement, the Company received its interest in GTS-Vox Limited, the intermediate holding company of TCM, in exchange for a note in the principal amount of $693,380 issued to the sellers and certain additional consideration to its partners payable in the form of either cash or Common Stock based upon its financial performance. The Company paid the note in 1996. On January 17, 1997, the agreement was amended such that the consideration would only be in the form of the issuance of Common Stock and as such, GTS is obligated under these arrangements to issue up to a maximum of 1,121,640 shares of Common Stock. In the first quarter of 1997, pursuant to this agreement the Company issued 504,600 common shares, which was valued at the Company's current fair market value of $13.33 per share. Common Stock issued pursuant to the agreement must be held for a minimum holding period. In certain circumstances, if GTS's partners are unable to sell their shares of Common Stock, GTS is obligated to assist in locating a purchaser for the Common Stock, and, if unable to do so, to repurchase these shares. GTS's repurchase

103

obligations are at the following prices: (i) if shares of Common Stock are then being publicly traded, at the average trading price of such shares for the 10 trading days preceding such repurchase or (ii) if shares of Common Stock are not then publicly traded, at the price shares of Common Stock were most recently offered to individual investors in a private placement, or, if no such private placement has occurred within the three months preceding the repurchase of such shares, at a price determined by an independent financial institution to be agreed upon by GTS and the seller. As a result of their receipt of shares of Common Stock in 1997, the sellers became shareholders of GTS.

GTS purchased its interest in PrimTelefone, the Company's cellular operations in the Primorsky region of Russia, from Commstruct International, B.V. ("CIBV") for $500,000 cash and 400,000 shares of Common Stock of the Company, as a result of which CIBV became a stockholder of the Company. Pursuant to the asset purchase agreement relating to the purchase by GTS of its interest in PrimTelefone, CIBV has the right to have some or all of its shares of Common Stock repurchased, which right will terminate on the date when the Company first sells shares of Common Stock to the public pursuant to an effective registration statement under the Securities Act, by GTS over a five-year period at the current fair market value of such shares at the time of such repurchase.

Affiliates of Baring International Investment Management Limited ("Barings"), which affiliates consist primarily of investment funds and trusts, are shareholders of the Company and Barings may designate a non-voting observer to attend meetings of the Board of Directors of the Company. Barings' observer status terminates upon the consummation of an initial public offering of the Company's Common Stock. In April 1996, GTS entered into an agreement with First NIS Regional Fund SICAF, an affiliate of Barings, to organize GTS Ukrainian TeleSystems, L.L.C. (the "LLC"), a Delaware limited liability company 60% owned by GTS, which in turn entered into a stock purchase agreement to acquire 49% of all the ownership interests in Bancomsvyaz, a Ukrainian limited liability company. See "Business -- Russia and the CIS." Such acquisition closed in May 1996. By contractual arrangement, Barings designates one member of the board of directors of Bancomsvyaz. Barings funded $4.5 million to be applied towards the LLC's purchase of the interest in Bancomsvyaz and for the LLC's $1.5 million contribution to the registered capital of Bancomsvyaz. Prior to March 1, 1999, Barings may put its initial investment to GTS for $4.5 million, plus accrued interest at 13.5% per annum, or, if GTS has consummated an initial public offering of its Common Stock, may exercise an option to convert such investment into 438,311 shares of Common Stock at an exercise price of $10.27. In June 1997 the agreement was amended, such that Barings funded an additional $4.1 million to be applied toward Bancomsvyaz's capital expenditure and operating capital requirements. On September 30, 2000, Barings may put that portion of its LLC interest represented by the additional Barings investment to GTS for $4.1 million, or if GTS has consummated an initial public offering of its Common Stock, may exercise an option to convert such additional investment into 275,000 Shares of Common Stock at an exercise price of $15.00.

In 1996, the Company issued $40 million of notes (the "Chatterjee Notes") to the Chatterjee Group, an affiliate of George Soros. In connection with the issuance of the Chatterjee Notes, the Chatterjee Group received warrants (the "Chatterjee Warrants") to purchase 4,444,443 shares of Common Stock. The Chatterjee Warrants were initially issued with an exercise price of $10.27 per share, which exercise price was subsequently reduced to $9.33 per share in accordance with the terms of the warrant agreement. In addition, The Chatterjee Group was granted the right to appoint, and has appointed, one member to the Board of Directors and collects a monitoring fee of $40,000 per month, which it will continue to collect until the Company completes the Offering. The Chatterjee Group also has the right to co-invest with GTS in all of its new ventures throughout Asia, excluding countries in the former Soviet Union, and pursuant to this right has invested and holds a 25% interest in GTS China Investments LLC. See "Business -- Asia -- Operations." The Chatterjee Notes bear interest at 10% per annum and the principal is payable in 12 quarterly installments commencing April 1, 1998.

In 1996, the Company also issued $30 million of notes (the "Capital Research Notes") to affiliates of Capital Research International. In connection with the issuance of the Capital Research Notes, Capital Research International received warrants (the "Capital Research Warrants") to purchase 3,333,333 shares of Common Stock.

CONVERTIBLE BONDS

The Company sold approximately $144.8 million bonds ("Convertible Bonds") in the Convertible Bond Offering. The Convertible Bonds have a three year maturity and are unsecured, senior subordinated obligations of the Company. The Convertible Bonds are issued pursuant to an indenture containing certain covenants for the benefit of the holders of the Convertible Bonds, including, among other things, covenants

106

limiting the incurrence of indebtedness, restricted payments, liens, payment restrictions affecting certain subsidiaries and joint ventures, transactions with affiliates, asset sales and mergers and combinations. In the event of a change of control of the Company, holders of the Convertible Bonds have the right to require GTS to purchase such holder's Convertible Bonds at prices ranging from 106.5 percent of the principal amount if the date of redemption occurs on or before June 30, 1998 to 121.0 percent of the principal amount if the date of redemption occurs after June 30, 1999. The Convertible Bonds bear interest at the rate of 8.75% per annum until maturity on June 30, 2000. The Company has granted to the holders of the Convertible Bonds certain rights with respect to the registration of the shares of Common Stock issuable upon conversion of the Convertible Bonds.

Each Convertible Bond is convertible into such number of shares of Common Stock as is equal to the principal amount of such Convertible Bond divided by the applicable Conversion Price. The applicable Conversion Prices shall be determined as follows: (i) where a Complying Public Equity Offering (as defined herein) has not been preceded since the issuance of the Convertible Bonds by a Non-Complying Equity Offering (as defined herein), the Conversion Price shall equal the per share price to the public in the Complying Public Equity Offering, provided, however, that a 7% or 15% discount will be given to Convertible Bond holders from the per share price to the public if the Complying Public Equity Offering occurs during the second or third year, respectively, from the date of issuance of the Bonds; (ii) where a Complying Public Equity Offering has been preceded by one or more Non-Complying Equity Offerings since the issuance of the Convertible Bonds, the Conversion Price shall equal the lower of (a) the dollar-weighted average conversion price for all of such Non-Complying Equity Offerings and the Complying Public Equity Offering (as calculated for each such offering at the gross per share offering price for the applicable offering, provided, however, that a 7% or 15% discount will be included in the calculation if the closing dates of such offerings occur during the second or third year, respectively from the date of issuance of the Convertible Bonds) and (b) the conversion price for the Complying Public Equity Offering (as calculated in (i) above); (iii) where a Non-Complying Public Equity Offering of at least $50 million, which is not a Complying Public Equity Offering solely by reason of the offering's failure to satisfy the $100,000,000 offering size condition for a Complying Public Equity Offering, has not been preceded by a Complying Public Equity Offering since the issuance of the Bonds and has been preceded by one or more Non-Complying Equity Offerings, the Conversion Price shall equal the lower of (a) the dollar-weighted average conversion price for all of such Non- Complying Equity Offerings and the Non-Complying Public Equity Offering (as calculated for each Non-Complying Public Equity Offering at the per share offering price for the applicable offering, provided, however, that a 7% or 15% discount will be included in the calculation if the closing dates of such offerings occur during the second or third year, respectively from the date of issuance of the Convertible Bonds) and (b) the conversion price for the Non-Complying Public Equity Offering alone or (iv) in the case of any other Non-Complying Equity Offering not provided for in clause (iii) above, where no Complying Public Equity Offering has occurred since the issuance of the Convertible Bonds, the Conversion Price shall equal the lowest conversion price calculated for each Non-Complying Equity Offering (as calculated for each such offering at the gross per share offering price provided, however, that a 7% or 15% discount will be included in the calculation if the closing dates of such offerings occur during the second or third year from the date of issuance of the Convertible Bonds).

There shall be excluded from the calculation of the applicable Conversion Price any private equity offerings of Common Stock (made pursuant to an exemption from registration under the Securities Act) aggregating no more than $100 million in gross proceeds if such offering or offerings are consummated on or prior to December 31, 1997 and certain private sales of the Common Stock to a strategic purchaser so long as there has occurred a Complying Public Equity Offering or a Non-Complying Equity Offering.

Outstanding Convertible Bonds are, subject to certain conditions, redeemable at the option of the Company on or after the second anniversary of a Complying Public Equity Offering, at the principal amount thereof plus accrued interest, if any. At maturity the Convertible Bonds will be redeemed at their principal amount plus accrued interest; however, in the event that a Complying Public Equity Offering has not occurred, outstanding Convertible Bonds will be redeemed at 121% of their principal amount, plus accrued interest, if any.

107

A "Complying Public Equity Offering" means a public offering of Common Stock where, immediately following completion thereof, (a) the following conditions are met: (i) the Company has made public offerings of Common Stock with a cumulative public offering price of at least $100,000,000 to an aggregate of not less than 50 purchasers; (ii) the Common Stock has been listed or shall be listed in connection with the offering on either the New York Stock Exchange, the London Stock Exchange, the American Stock Exchange or the Nasdaq National Market; and (iii) the Company shall have registered additional shares of Common Stock from private offerings of Common Stock (made pursuant to an exemption from registration under the Securities Act) with a market value of at least $100,000,000 calculated using the offering price in the Complying Public Equity Offering and (b) the aggregate number of shares of Common Stock sold thereby, together with any Common Stock sold in any prior public offerings plus the number of shares of Common Stock into which the Convertible Bonds may be converted (calculated as if such conversion were to be effected on the date of determination) does not exceed 50 percent of the total number of shares of Common Stock outstanding on a fully diluted basis. A "Non-Complying Public Equity Offering" means a public equity offering of Common Stock which satisfies all of the conditions specified in (a) above, except that the cumulative public offering price is less than $100,000,000. A "Non-Complying Equity Offering" means (i) a private offering of Common Stock or (ii) a public offering of Common Stock that is not a Complying Public Equity Offering.

HER NOTES

HER sold $265 million aggregate principal amount of 11 1/2% Senior Notes due 2007 ("HER Notes") in August, 1997. The HER Notes have a ten year maturity and are unsecured, senior obligations of HER. HER placed approximately $56.5 million of the net proceeds in escrow for the first two years' interest payments on the HER Notes. The HER Notes were issued pursuant to an indenture containing certain covenants for the benefit of the holders of HER Notes, including, among other things, covenants limiting the incurrence of indebtedness, restricted payments, liens, payment restrictions affecting certain subsidiaries and joint ventures, transactions with affiliates, assets sales and mergers. The HER Notes are redeemable in whole or part, at the option of HER at any time on or after August 15, 2002 at a price ranging from 105.75 percent to 100.0 percent of the principal amount.

A portion of the HER Notes are also redeemable at any time or from time to time prior to August 15, 2000 at a redemption price equal to 111.5% of the principal amount of the HER Notes so redeemed, plus accrued and unpaid interest thereon, if any, to the date of redemption with the net cash proceeds of one or more public equity offerings or strategic equity investments resulting in aggregate gross cash proceeds to HER of at least $75 million. In the event of a change of control of HER, holders of the HER Notes have the right to require HER to purchase such holder's HER Notes at a price equal to 101% of the aggregate principal amount.
