CAPITALIZATION

The following table sets forth the capitalization of the Company as of June 30, 1998, (i) on an actual basis and (ii) as adjusted to reflect the conversion of all outstanding shares of Preferred Stock into Common Stock and the sale of 3,000,000 shares of Common Stock offered by the Company hereby at an assumed initial public offering price of $14.00 per share and the receipt of the estimated net proceeds therefrom.

DILUTION

The net tangible book value of the Company at June 30, 1998 was approximately $3,642,000 or $0.28 per share. Pro forma net tangible book value per share is determined by dividing the Company's tangible net worth (tangible assets less liabilities) by the number of shares of Common Stock outstanding, after giving effect to the conversion of Preferred Stock upon completion of this offering. After giving effect to the sale by the Company of the 3,000,000 shares of Common Stock offered hereby at an assumed initial public offering price of $14.00 per share, after deducting estimated underwriting discounts and commissions and offering expenses, the pro forma net tangible book value of the Company as of June 30, 1998 would have been $41,302,000, or $2.55 per share. This represents an immediate increase in net tangible book value of $2.27 per share to existing stockholders and an immediate dilution in net tangible book value of $11.45 per share to new investors purchasing shares at the assumed initial public offering price. The following table illustrates this per share dilution:

The following table summarizes, on a pro forma basis as of June 30, 1998, the difference between the number of shares of Common Stock purchased from the Company, the total consideration paid and the average price per share paid by the existing stockholders and by the new investors (at an assumed initial public offering price of $14.00 per share for shares purchased in this offering, before deducting estimated underwriting discounts and commissions and offering expenses):

(1) The foregoing computations assume no exercise of outstanding stock options. As of June 30, 1998, options were outstanding to purchase 2,483,292 shares at a weighted average exercise price of $2.50 per share and warrants were outstanding to purchase 3,088,462 shares at a weighted average exercise price of $6.64 per share. To the extent that outstanding options and warrants are exercised, there will be further dilution to new investors.

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

The following discussion and analysis should be read in conjunction with "Selected Consolidated Financial Data" and the Company's Consolidated Financial Statements and Notes included elsewhere in this Prospectus. The discussion in this Prospectus contains forward-looking statements that involve risks and uncertainties, such as statements of the Company's plans, objectives, expectations and intentions. The cautionary statements made in this Prospectus should be read as being applicable to all related forward- looking statements wherever they appear in this Prospectus. The Company's actual results could differ materially from those discussed here. Factors that could cause or contribute to such differences include those discussed in "Risk Factors," as well as those discussed elsewhere herein. See "Risk Factors" and "Information Regarding Forward-Looking Statements."

OVERVIEW

Terayon develops, markets and sells cable modem systems based upon its S- CDMA technology. Since its inception in January 1993, the Company has focused on the development of its S-CDMA technology, as well as certain other core technologies, to enable broadband transmission of data over cable networks. The Company commenced the specifications and design of its first ASIC in October 1994 and produced the first version of this ASIC in June 1996. The Company concurrently developed an end-to-end broadband access system, the TeraComm system, around the ASIC. During late 1996 and through 1997, the Company commenced limited field trials of the TeraComm system with several cable operators. In the first quarter of 1998, the Company commenced volume shipments to a small number of cable operators. The Company recognized revenues of $2.1 million in the year ended December 31, 1997 and $9.4 million for the six months ended June 30, 1998. The Company generally recognizes product revenues upon shipment of products to customers. Future agreements with certain distribution partners may contain price protection provisions and certain return rights. The Company's existing agreements currently do not contain such provisions.

The Company sells its products both in the United States and internationally and markets its products primarily to cable operators and distributors. To date, a small number of customers has accounted for all of the Company's sales. In 1997, sales to Telegate, Sumitomo and NET Brasil represented approximately 30%, 29% and 14%, respectively, of the Company's revenues. In the first six months of 1998, sales to Shaw, Sumitomo and Cablevision represented approximately 40%, 14% and 10%, respectively, of the Company's revenues. The Company expects that sales to a limited number of customers will continue to account for a substantial portion of the Company's sales for the foreseeable future. If orders from significant customers are delayed, cancelled or otherwise fail to occur in any particular period, or if any significant customer delays payment or fails to pay, the Company could experience significant operating losses in such period. As a result, the Company expects to experience significant fluctuations in its operating results on a quarterly and annual basis. See "Risk Factors--Dependence on Small Number of Customers," "--Dependence on Cable Industry to Upgrade to Two- Way Cable Infrastructure" and "--Ability to Market Effectively to Cable Operators."

The market for broadband access products and services is intensely competitive and is characterized by rapid technological change, new product development and product obsolescence, evolving industry standards and significant price erosion of products over time. The Company has experienced and expects to continue to experience downward pressure on its unit ASPs. The Company has had negative gross margins since inception. While the Company has initiated cost reduction programs to offset pricing pressures on its products, there can be no assurance that these cost reduction efforts will continue to keep pace with competitive price pressures or lead to improved gross margin. If the Company is unable to reduce costs efficiently, its gross margin and profitability will continue to be adversely affected. The Company's gross margin also is affected by the sales mix of TeraLink 1000 Master Controllers, TeraLink

26

Gateways and TeraPro cable modems, as the TeraPro modems have significantly lower margins than the TeraLink 1000 Master Controllers and TeraLink Gateway headend products. For the foreseeable future, the Company expects to achieve negative or nominal margins on TeraPro cable modems and expects that sales of TeraPro cable modems will continue to constitute a significant portion of its revenues. As a result of these factors, the Company's gross margins and operating results are likely to be adversely affected in the near term. See "Risk Factors--Market Acceptance of Cable Modems; Competing Technologies," "-- Ability to Achieve Cost Reductions," "--Limited Manufacturing Experience and Dependence on Contract Manufacturer," "--Erosion of Average Selling Prices" and "--Highly Competitive Industry; Established Competitors."

The Company's ability to generate revenues also depends on guaranteeing the availability of supplies from its sole sources, increasing the manufacturing and testing capacity of its products by a contractor while ensuring product quality, and continuing deployment of its products by existing and new customers. In the first quarter of 1998, the Company transitioned its manufacturing operations from CMC to Solectron. The Company recorded a charge of $1.3 million in the first quarter of 1998 relating to the write-off of obsolete inventory and the transition of manufacturing operations to Solectron. The Company currently tests and assembles the TeraLink 1000 Master Controller and the TeraLink Gateway headend equipment at its Santa Clara facility. Finished TeraPro cable modems are drop shipped by Solectron to Terayon customers. See "Risk Factors--Limited Manufacturing Experience and Dependence on Contract Manufacturer."

The Company sustained net losses of $3.7 million, $10.7 million, $22.5 million and $11.3 million for the years ended December 31, 1995, 1996 and 1997 and for the six months ended June 30, 1998, respectively. As a result, the Company had an accumulated deficit of $48.5 million as of June 30, 1998. The Company's operating expenses are based in part on its expectations of future sales, and the Company expects that a significant portion of its expenses will be committed in advance of sales. As a result, net income may be adversely affected by a reduction in sales if the Company is unable to adjust expenses quickly in response to any decrease in sales. The Company expects to increase significantly expenditures in technical development, sales and marketing and manufacturing as it engages in activities related to product enhancement, cost reduction and commercialization of new products. Additionally, the Company expects to increase capital expenditures and other operating expenses in order to support and expand the Company's operations. As a result, the Company expects to continue to incur losses for the foreseeable future. There can be no assurance that the Company will achieve or sustain profitability in the future. See "Risk Factors--Early Stage of Development; History of Losses," "-- Fluctuations in Operating Results" and "--Lengthy Sales Cycle."

RESULTS OF OPERATIONS

SIX MONTHS ENDED JUNE 30, 1997 AND 1998

Revenues. The Company had revenues of $93,000 for the six months ended June 30, 1997, as the Company did not commence selling its products until June 1997. For the six months ended June 30, 1998, the Company had revenues of $9.4 million, primarily due to sales of headend controllers, cable modems and, to a lesser extent, telephony modules.

Cost of Goods Sold. Cost of goods sold consists of direct product costs as well as the cost of the Company's manufacturing operations group, which cost consists of assembly, test and quality assurance for products, warranty costs and associated costs of personnel and equipment. For the six months ended June 30, 1997, the Company incurred $482,000 in cost of goods sold primarily related to the costs of the manufacturing operations group as it prepared for commercialization of the Company's products. The Company incurred $11.5 million in cost of goods sold for the six months ended June 30, 1998, which included a charge of $1.3 million relating to the write-off of obsolete inventory and the transition of manufacturing operations to Solectron.

27

Gross Profit (Loss). The Company incurred a gross loss of $389,000 for the six months ended June 30, 1997 due to costs associated with the Company's manufacturing operations group. The Company incurred a gross loss of $2.1 million for the six months ended June 30, 1998, primarily due to manufacturing costs spread over low volumes of products sold, together with a charge of $1.3 million relating to the write-off of obsolete inventory and the transition of manufacturing operations to Solectron.

Research and Development. Research and development expenses consist primarily of personnel costs, as well as design expenditures, equipment and supplies required to develop and enhance the Company's products. Research and development expenses decreased from $5.9 million in the six months ended June 30, 1997 to $4.9 million in the six months ended June 30, 1998 as a result of timing of the Company's development projects. The Company intends to continue to increase investment in research and development programs in future periods for the purpose of enhancing current products, reducing the cost of current products and developing new products.

Sales and Marketing. Sales and marketing expenses consist primarily of salaries for sales, marketing and support personnel, and costs related to tradeshows, consulting and travel. Sales and marketing expenses increased from $1.5 million in the six months ended June 30, 1997 to $3.0 million in the six months ended June 30, 1998, primarily due to increased payroll costs related to additional sales and support personnel for commercial trials and deployment of the Company's products. The Company expects sales and marketing expenses to increase in the future as the Company expands its customer base.

General and Administrative. General and administrative expenses primarily consist of salary and benefits for administrative officers and support personnel, travel expenses, legal, accounting and consulting fees. General and administrative expenses increased from $1.1 million in the six months ended June 30, 1997 to $1.3 million in the six months ended June 30, 1998. The Company expects that general and administrative expenses will increase as a result of the additional reporting requirements imposed on the Company as a public company and increased infrastructure to support expanded activities of the Company.

Net Interest Income (Expense). Net interest income was $123,000 in the six months ended June 30, 1997 compared to net interest expense of $32,000 in the six months ended June 30, 1998. The decrease primarily was a result of lower interest income on lower average cash balances and higher interest expense on term debt in the six months ended June 30, 1998.

YEARS ENDED DECEMBER 31, 1995, 1996 AND 1997

Revenues. The Company did not recognize any revenues from product sales in 1995 or 1996, as the Company did not commence selling its products until June 1997. The Company recognized product revenues of $1.6 million in 1997, primarily due to sales of headend controllers and cable modems. A majority of the products shipped during 1997 were for customer trial purposes. During 1997, the Company also recognized $480,000 of technology development revenues pursuant to a technology development agreement (the "Development Agreement") to provide telephony modules to a telecommunications systems manufacturer. The Company does not expect significant revenues to be recognized pursuant to the Development Agreement in the future.

Cost of Goods Sold. In 1995, the Company incurred $676,000 in cost of goods sold as a result of technology development costs incurred pursuant to the Development Agreement. The Company did not incur any cost of goods sold in 1996. The Company incurred $6.5 million in cost of goods sold in 1997, reflecting the costs of the Company's manufacturing operations group for the full year and direct product costs related to sales that occurred primarily in the last six months of 1997.

28

Gross Profit (Loss). The Company incurred a gross loss of $676,000 in 1995 due to technology development costs incurred pursuant to the Development Agreement. The Company did not realize any gross profit or loss in 1996. The Company incurred a gross loss of $4.3 million in 1997, primarily due to manufacturing costs for the full year spread against revenues recognized primarily in the last six months of 1997. The manufacturing costs incurred in the first six months of 1997 consisted of pre-production activities related to preparation for commercialization of the Company's products.

Research and Development. Research and development expenses increased from $2.0 million in 1995 to $8.0 million in 1996, primarily due to increased number of personnel and related labor costs and approximately $1.5 million of prototype and non-recurring engineering costs related to the development of the Company's initial products. Research and development expenses increased from $8.0 million in 1996 to $11.3 million in 1997 due to increased staffing and associated engineering costs related to new and existing product development.

Sales and Marketing. Sales and marketing expenses increased from $205,000 in 1995 to $1.1 million in 1996, primarily as a result of increased number of personnel and related labor costs and costs related to promotional activities and early trials of the Company's products. Sales and marketing expenses increased from $1.1 million in 1996 to $4.5 million in 1997, primarily due to increased payroll costs related to additional sales and support personnel for commercial and market trials and the commercial launch of the Company's products.

General and Administrative. General and administrative expenses increased from $825,000 in 1995 to $1.8 million in 1996, primarily due to increased hiring and higher legal and travel expenses related to preparations for the commercial release of the Company's products. General and administrative expenses increased from $1.8 million in 1996 to $2.5 million in 1997, due to increased number of personnel and related payroll costs and higher legal and executive travel expenses.

Net Interest Income (Expense). Net interest income increased from $68,000 in 1995 to $253,000 in 1996, as a result of increased cash balances during 1996 resulting from the Company's financing activities during those periods. Net interest income decreased from $253,000 in 1996 to $128,000 in 1997, primarily as a result of higher interest expense due to larger loan balances.

Revenues increased in each of the consecutive three month periods due to commencement of commercial shipment of the Company's products in June 1997. The Company incurred increasing gross losses and declining gross margin in the second half of 1997 as the Company commenced sales of cable modems which, due to low volume production quantities and resulting high manufacturing costs and per-unit overhead allocations, were sold at negative margins. Revenues for the fourth quarter of 1997 include $480,000 of product development revenues related to the Company's development of a telephony module for a telecommunications system manufacturer. Gross margin improved in the first and second quarters of 1998 as unit volume sales increased and unit manufacturing costs declined. Gross margin also improved in the period due to a change in product mix, with a higher ratio of higher margin headend products sold relative to lower margin cable modems. Operating expenses varied in the last four quarters ended June 30, 1998 due to the timing of research and development projects and due to significant trade shows in the fourth quarter of 1997 and the second quarter of 1998.

The Company has experienced, and expects to continue to experience, fluctuations in its operating results on a quarterly and an annual basis. Historically, the Company's quarterly revenues have been unpredictable due to a number of factors. Factors that have influenced and will continue to influence the Company's operating results include: a long sales cycle for the Company's products; competitive pricing pressures; the effects of extended payment terms, promotional pricing, service, marketing or other terms offered to customers; accuracy of customer forecasts of end user demand; personnel changes; quality control of products sold; and regulatory changes or delays in obtaining required regulatory approvals. For example, the Company's product shipments to date to a customer in Brazil have been significantly lower than anticipated, due to delays in certain regulatory approvals in Brazil. There can be no assurance that similar delays will not occur in other countries in which the Company

30

is marketing or plans to market its products. Any such delays would have an adverse effect on the Company's operating results for a particular period. Factors that may influence the Company's operating results in the future include: the size and timing of customer orders and subsequent shipments; customer order deferrals in anticipation of new products or technologies; timing of product introductions or enhancements by the Company or its competitors; market acceptance of new products; technological changes in the cable, wireless and telecommunications industries; changes in the Company's operating expenses; customers' capital spending; delays of orders by customers; customers' delay in or failure to pay accounts receivable; and general economic conditions. See "Risk Factors--Fluctuations in Operating Results."

INCOME TAXES

The Company has not generated any net income to date and therefore has not accrued any income taxes since its inception. The Company accounts for income taxes under Statement of Financial Accounting Standards No. 109. Realization of deferred tax assets is dependent on future earnings, if any, the timing and amount of which are uncertain. Accordingly, valuation allowances in amounts equal to the net deferred tax assets as of December 31, 1997 and 1996 have been established to reflect these uncertainties.

At December 31, 1997, the Company had federal and state net operating loss carryforwards of $31.0 million and $15.0 million, respectively, and federal and state tax credit carryforwards of $1.7 million and $1.2 million, respectively, that will expire at various dates beginning in 1999 through 2012, if not utilized. Utilization of net operating loss and tax credit carryforwards may be subject to a substantial annual limitation due to the ownership change limitations provided by the Internal Revenue Code of 1986, as amended, and similar state provisions. The annual limitation may result in the expiration of net operating loss and tax credit carryforwards before full utilization.

STOCK-BASED COMPENSATION

With respect to certain stock option grants in 1997 and the first six months of 1998, the Company had recorded deferred compensation of $2.1 million as of June 30, 1998. The Company amortized approximately $12,000 of the deferred compensation in 1997 and $106,000 in the first six months of 1998, and will amortize the remainder over the related vesting period of the stock options. The future compensation charges are subject to reduction for any employee who terminates employment prior to the expiration of such employee's vesting period. See Note 8 of Notes to Consolidated Financial Statements.

LIQUIDITY AND CAPITAL RESOURCES

Since its inception through June 30, 1998 the Company met its liquidity needs primarily through private sales of preferred stock for aggregate proceeds of $52.7 million, before deduction of issuance costs.

Since its inception, the Company has used cash in operating activities of $41.0 million through June 30, 1998. Cash used in operating activities in 1995, 1996, 1997 and the first six months of 1998 was $2.3 million, $9.4 million, $20.8 million and $8.5 million, respectively. In 1995, 1996 and the first six months of 1998, cash used in investing activities was $1.3 million, $6.5 million and $309,000, respectively. Investment activities in 1995 and the first six months of 1998 consisted primarily of the purchase of hardware, software and test equipment and in 1996 consisted primarily of the purchase of short- term investments. Cash provided by investing activities, primarily from the sales of short-term investments, was $1.5 million in 1997.

At June 30, 1998 the Company had approximately $6.0 million in cash and cash equivalents and a $10.0 million revolving line of credit. At June 30, 1998, the Company was in violation of certain covenants under its line of credit.

31

The Company believes that its cash balances and funds available under the bank line of credit, together with the proceeds of this offering, will be sufficient to satisfy its cash requirements for at least the next 12 months. There can be no assurance, however, that the Company will not require additional financing prior to such time to fund its operations and it may seek to raise such additional funds through the sale of public or private equity or debt financing or from other sources. The sale of additional equity or debt securities may result in additional dilution to the Company's stockholders. There can be no assurance that any additional financing will be available to the Company on acceptable terms, or at all, when required by the Company. See "Risk Factors--Significant Future Capital Requirements."

YEAR 2000

Many existing computer systems and applications and other control devices use only two digits to identify a year in the date field, without considering the impact of the upcoming change in the century. As a result, in less than two years, computer systems and applications used by many companies may need to be upgraded to comply with Year 2000 requirements. Significant uncertainty exists in the computer industry concerning the potential effects associated with such compliance. The Company relies on computer systems in operating and monitoring many significant aspects of its business, including financial systems (such as general ledger, accounts payable, accounts receivable, inventory and order management), customer services, infrastructure and network and telecommunications equipment. The Company also relies directly and indirectly on the systems of external enterprises such as customers, suppliers, creditors, financial organizations and domestic and international governments. The Company currently estimates that its costs associated with Year 2000 compliance, including any costs associated with the consequences of incomplete or untimely resolution of Year 2000 compliance issues, will not have a material adverse effect on the Company's business, financial condition or results of operations in any given year. However, the Company has not extensively investigated and does not believe that it has fully identified the impact of Year 2000 compliance and has not concluded that it can resolve any issues that may arise in connection with Year 2000 compliance without disruption of its business or without incurring significant expense. In addition, even if the Company's internal systems are not materially affected by Year 2000 compliance issues, the Company could be affected through disruption in the operation of the enterprises with which the Company interacts. There can be no assurance that the Company's products will be Year 2000 compliant, that third-party products with which the Company's products interface will be Year 2000 compliant or that any changes to third-party products made in response to Year 2000 compliance issues will not render the Company's products incompatible with such third-party products.

RECENT FINANCIAL ACCOUNTING PRONOUNCEMENTS

In June 1997, the Financial Accounting Standards Board ("FASB") issued Statement No. 130, Reporting Comprehensive Income. This statement requires that all items that are to be required to be recognized under accounting standards as components of comprehensive income be reported in a financial statement that is displayed with the same prominence as other financial statements. This statement is effective for fiscal years beginning after December 15, 1997, and will be adopted by the Company for the year ended December 31, 1998.

In June 1997, FASB issued Statement No. 131, Disclosures About Segments of an Enterprise and Related Information. This statement replaces Statement No. 14, Financial Reporting for Segments of a Business Enterprise, and changes the way public companies report segment information. This statement is effective for fiscal years beginning after December 15, 1997 and will be adopted by the Company for the year ended December 31, 1998.

BUSINESS

OVERVIEW

Terayon develops, markets and sells cable modem systems that enable cable operators to cost-effectively deploy reliable two-way broadband access services. The Company's TeraComm system is designed to allow cable operators to minimize time-consuming and costly network infrastructure upgrades, achieve reduced time to market and provide a wide range of service levels to residential and commercial end users. Cable operators using the TeraComm system are able to provide additional revenue-generating services to end users, enabling cable operators to compete effectively in the emerging market for broadband access services.

The Company's TeraComm system, comprised of the TeraPro cable modem, the TeraLink 1000 Master Controller, the TeraLink Gateway and the TeraView Element Management and Provisioning Software, is based on Terayon's S-CDMA technology. S-CDMA enables reliable two-way broadband communications over both pure coaxial and HFC cable infrastructure by maximizing resistance to noise that interferes with data transmissions over previously unusable frequency spectrum.

INDUSTRY BACKGROUND

DEMAND FOR BROADBAND ACCESS

In recent years, the volume of bandwidth intensive data, voice and video traffic across the Internet, corporate intranets and other public networks has increased dramatically. This demand has been driven by the proliferation of residential and commercial computer users that are accessing networks in a variety of applications, including communications via the Internet, electronic commerce and telecommuting. These applications often require the transmission of large, multimedia-intensive files. IDC estimates that the number of Internet users will increase from approximately 69 million at the end of 1997 to approximately 320 million by the end of 2002. IDC also estimates that the number of home office households will increase from approximately 35 million at the end of 1997 to approximately 50 million by the end of 2002.

Despite significant advances in the performance of computer processors and data backbone networks, high speed data transmission has been limited by the existing local access network infrastructure (the local loop), which is not optimized for distribution of data-intensive multimedia content. Users of dial- up analog modems with maximum data rates of only 28.8 Kbps to 56 Kbps often experience frustration, as they encounter frequent and lengthy delays or complete failures in transmission. In response to the growing demand for increased bandwidth, the communications industry has begun to deploy new broadband access technologies that can deliver megabit per second ("Mbps") or better performance to end users.

ADVANTAGES OF CABLE MODEMS OVER ALTERNATIVE BROADBAND ACCESS TECHNOLOGIES

As residential and commercial demand for faster Internet access continues to grow, particularly for applications such as streaming audio and video, IP telephony and interactive two-way video, service providers are investing in enabling infrastructure and technologies. Various technologies have emerged to address the need for broadband access. The leading technologies include ISDN, ADSL and xDSL technologies being marketed by telecommunications companies, and cable infrastructure technologies such as cable modems being marketed by cable operators. These digital technologies offer substantial performance increases over traditional analog 56 Kbps dial-up modem technologies.

Of the digital technologies, cable modems currently provide the highest available two-way transmission speeds and their "always on" availability eliminates the tedious and unreliable dial-up process of other technologies. The existing cable infrastructure offers other important advantages over alternative broadband architectures. Currently, the cable infrastructure passes over 95% of homes in the United States and a large number of small businesses. In addition, the cable infrastructure has the capacity to offer a wide range of broadband services, such as digital TV, Internet access and IP telephony. Many cable operators have recognized the need to expand beyond broadcast and video TV services to diversify their business and remain competitive. A growing number of cable operators have already expanded their business to include data- over-cable services through affiliations with service providers such as @Home and Road Runner, and several cable operators are exploring voice-over-cable services as well. Kinetic Strategies Inc. estimates that over 200,000 North American homes currently have data-over-cable services.

LIMITATIONS OF EXISTING CABLE INFRASTRUCTURE

Most cable networks were designed to provide one-way video broadcast from the cable headend to subscribers. Data-over-cable and other two-way services require cable operators to provide an upstream return path from subscribers to the headend. Noise interferes with upstream signal transmissions, potentially resulting in corrupted information or service outages. Common noise problems are (i) "ingress noise," a relatively constant level of interference resulting from home appliances and consumer electronics leaking noise into the cable system through imperfections in the cable plant, such as faulty connections or cracked cable shielding and (ii) "impulse noise," which is transient, unpredictable interference that results from home appliances switching on and off. Noise is a particular problem in the upstream return path because each home's noise is aggregated into the headend. In addition, the 5 to 42 MHz frequency spectrum reserved for subscriber-to-headend transmissions is highly susceptible to ingress and impulse noise.

CABLE OPERATOR OBJECTIVES IN DEPLOYING BROADBAND ACCESS SERVICES

In order to successfully exploit the opportunities offered by the increasing demand for broadband access, cable operators face a number of challenges.

Cost-effectively manage system noise. Cable modems based on current- generation TDMA technologies typically require a Signal-to-Noise Ratio ("SNR") of 20dB or better for reliable operation. To respond to ingress noise, cable operators using cable modems based on TDMA often must upgrade their networks to an HFC architecture. An upgrade to an HFC system includes replacing a substantial portion

34

of the existing coaxial network with optical fiber, replacing the headend transmission equipment with optical transmission systems and providing additional interface layers between the optical fiber and the coaxial connection into the home.

To further address ingress noise and attempt to prevent impulse noise interference, cable operators must often completely rebuild their HFC network. This entails dividing the network into smaller segments, to isolate noise and therefore limit the aggregate noise arriving at the headend, as well as replacing coaxial drops in the homes of subscribers for data services and placing filters on non-subscriber homes. In addition, many TDMA-based systems employ a frequency-agile scheme where the transmission system will shift transmission to a pre-reserved backup channel if the primary channel is affected by a noise event. Despite these expenditures, cable operators using TDMA may still be required to increase routine maintenance procedures in order to provide reliable service and to restrict two-way services to a limited portion of the 5 to 42 MHz frequency spectrum where noise events are less likely to occur. To reduce these costs and improve the quality of their service, cable operators require new upstream transmission technologies that address both ingress and impulse noise.

Minimize network capital equipment costs. Noise levels are directly related to the number of homes passed by a network, regardless of the number of subscribers on such network. As a result, the number of homes that can be supported by a single TDMA-based cable modem headend is limited, even in the early phase of deployment, when the number of subscribers may be very small. Cable operators using TDMA technology are often required to deploy a large number of headends to create a large service area "footprint." Minimizing initial investments and attaining "pay-as-you-go" capability that allows revenues to support incremental investment are vital to the ability of cable operators to enter the broadband access market.

Time to market. As telecommunications operators move quickly to offer broadband services, the Company believes that a cable operator's success in a particular geographic market will be determined by being first to market with broadband access services. Therefore, the Company believes that cable operators will need the ability to accelerate cable modem deployments in order to enhance their competitive position.

Ability to offer tiered services. The Company believes that cable operators can benefit from having a network capable of offering tiered services that allow them to maximize revenue from bandwidth allocated to those services. For example, a residential end user who only utilizes e-mail or Internet access may only be willing to pay a small premium over the cost of a dial-up connection, while commercial end users may be willing to pay a substantial premium for guaranteed bandwidth. In order to offer multiple tiers of service with varied access speeds and priority connections, cable operators need the ability to assign a portion of shared bandwidth to individual end users.

To meet these challenges, cable operators require a highly reliable broadband access solution that can be deployed rapidly at low initial costs, that enables cable operators to maximize revenues from available bandwidth capacity, and that scales as the number of broadband access subscribers increases.

THE TERAYON SOLUTION

The Company's TeraComm system is designed to enable cable operators to minimize time-consuming and costly network infrastructure upgrades, achieve reduced time to market and provide a wide range of service levels to residential and commercial end users. Cable operators using the TeraComm system are able to provide additional revenue-generating services to end users, enabling cable operators to compete effectively in the emerging market for broadband access services. The Company's system is based on its spread- spectrum technology, S-CDMA, which offers cable operators the following advantages:

35

Minimize cable infrastructure upgrades. Terayon's S-CDMA technology operates at extremely low SNRs, which enables Terayon's cable modems to be deployed on pure coaxial or HFC-upgraded systems, with minimal system upgrades. TDMA-based systems, which demand higher SNRs for operation, often require costly system upgrades or complete rebuilds to high quality HFC in order to support comparable broadband access services.

Reduce time to market. Activating two-way transmission by installing the TeraComm system does not require the time-consuming network upgrades or rebuilds usually required to support TDMA-based transmission equipment. As a result, cable operators can accelerate cable modem deployment and reduce their time to market with broadband access services, thereby enhancing their competitive position.

Minimize initial headend capital equipment costs. By deploying the TeraComm system, cable operators can minimize the initial capital expense for headend equipment. The noise-resistant properties of S-CDMA allow more cable segments to be aggregated to form a single shared upstream channel. These properties provide cable operators with a cost-effective solution during initial stages of deployment even with a limited number of users. As the number of users increases, additional Terayon equipment can be installed for a smooth transition to a larger-scale network. For large deployments, the routed architecture of Terayon's system will support a large number of headends, enabling cable operators to effectively manage thousands of subscribers as a single IP network with multiple logical sub-networks. In contrast, TDMA-based systems only support a smaller number of homes passed per headend due to susceptibility to noise-related service problems.

Increase signal transmission reliability. Cable operators who plan to offer broadband access services must demonstrate the ability to provide reliable and continuous service. S-CDMA enables cable operators to maintain signal transmission even in high noise environments. Further, S-CDMA's rate-adaptive response to sudden changes in plant conditions prevents even short service outages, unlike alternative systems that utilize a frequency-agile scheme, which can result in a loss of service.

Maximize spectrum usage. The TeraComm system is designed to operate effectively in the lowest frequency ranges of the upstream spectrum, where noise is too severe to allow the operation of TDMA-based systems. As a result, cable operators who employ the TeraComm system can utilize more of the existing upstream bandwidth than alternative broadband access technologies.

Generate additional revenue through tiered services. The high capacity and dynamic bandwidth management capabilities of the TeraComm system are designed to enable cable operators to offer a wide range of services at tiered prices. Cable operators can emulate high margin commercial-service offerings such as T-1, frame-relay and leased lines in the same network as lower margin, residential, Internet access.

Reduce ongoing cable infrastructure maintenance costs. Cable operators utilizing the TeraComm system can capitalize on S-CDMA's noise-resistant properties, which enable cable operators to operate plants in a wide range of conditions, thus reducing on-going maintenance costs and minimizing service problems. For example, while all cable operators monitor their networks on a regular basis, cable operators using TDMA-based systems are generally required to take more frequent corrective action than cable operators using S-CDMA- based systems to prevent normal "wear and tear" on the cable system from impacting service.

The Company's objective is to be the leading provider of cable modem systems to cable operators seeking to provide broadband access services to residential and commercial end users. Key elements of the Company's strategy are as follows:

Supply leading cable operators worldwide. The Company's initial target market is the ten largest cable companies in each major geographic area. In most markets, a small number of large cable operators often provide services to a majority of subscribers in a specific region and thus influence the purchase decisions of smaller cable operators. In the United States, ten cable operators together own and operate facilities passing approximately 74% of total homes passed. To date, three of the largest North American cable operators are deploying the TeraComm system commercially.

Establish relationships with industry leaders. The Company seeks to provide cable operators with a complete broadband access solution by establishing relationships with networking companies, systems integrators and other industry leaders. For example, the Company has a co-development agreement with Cisco to create an integrated headend solution. Additionally, the Company and @Home have integrated the Company's products with @Home's service. The Company will continue to pursue strategic relationships to expand the capabilities of its system.

Expand worldwide distribution channels. The Company intends to continue to increase its direct sales efforts and to establish strategic relationships with leading distributors worldwide. The Company's distribution strategy is to customize its sales and distribution efforts to address the specific needs of each market. For example, the Company has an agreement with Sumitomo, through its subsidiary Crossbeam Networks Corporation ("Crossbeam"), to distribute the Company's products in Japan. In Latin America, Europe and other parts of Asia the Company has appointed local distributors with expertise in their specific geographic regions. In the United States, the Company has begun to establish distribution relationships to provide broadband access solutions to smaller cable operators.

Provide superior customer service and support. The Company believes that its ability to provide consistent high quality service and support will be a key factor in attracting and retaining customers. In addition to assigning a field applications engineer to each customer account, the Company provides its customers with technical support and training through customer support representatives and representatives of distributors. The Company provides service and support to its customers 24 hours a day, 7 days a week.

Adopt and advocate industry standards. The rapidly evolving market in which the Company participates has recently adopted DOCSIS for cable modem standards, and the industry has commenced discussion of a next-generation cable modem standard, DOCSIS 2.0. The Company is developing a next-generation product, known as the UCM, which is intended to offer a mode of operation compliant with DOCSIS. The Company is actively participating in industry standard-setting efforts and intends to work with the MCNS consortium to incorporate S-CDMA into the DOCSIS 2.0 standard.

Leverage S-CDMA technology. The Company believes that its S-CDMA technology provides significant advantages over alternative broadband access technologies. The Company's team of engineers has extensive experience in many areas of broadband access system design, including communication systems, ASICs, data networking, RF, software and hardware. The Company intends to leverage these engineering capabilities to expand the features and functionality of its S-CDMA technology, and to apply S-CDMA to additional applications such as IP telephony, wireless communications and LMDS.

TECHNOLOGY

Terayon's products are based on the Company's S-CDMA technology. S-CDMA is integrated into a single ASIC chip, which implements the physical ("PHY") layer and media access control ("MAC") layer

37

communication protocols in the TeraComm system. S-CDMA is the primary differentiator between Terayon's cable modems and those of competitors who use TDMA-based technology for the PHY and MAC layer protocols. S-CDMA is designed to maximize resistance to noise, optimize use of network capacity and provide cable operators with multiple revenue streams through the ability to offer multiple Quality of Service levels.

Maximum noise resistance through spread spectrum and rate adaptive technologies. S-CDMA, like asynchronous Code Division Multiple Access ("CDMA") commonly used in mobile communications, is a form of spread spectrum technology. Spread spectrum technology was originally designed for use by the military to provide reliable and secure communications in harsh RF environments. The RF environment is subject to a variety of noise sources that can interfere with the transmission of data. In spread spectrum systems, data is transmitted by spreading the information across a range of frequencies and across a period of time, allowing sufficient information reception for the data to be reconstructed by the receiver. Data is encoded by transmitters in unique spreading codes that allow multiple data streams to be received and decoded by the receiver simultaneously. Therefore, noise events that are typically specific to a particular frequency or a period of time do not significantly interfere with transmission

In addition to spread spectrum, S-CDMA incorporates other techniques, including forward error correction and interleaving, that further enhance the ability of S-CDMA to resist impulse and ingress noise. In extremely harsh noise environments, S-CDMA incorporates a rate adaptive mode of operation that changes modulation schemes, reducing capacity, but allowing continued reliable transmission. This combination of techniques enables S-CDMA-based systems to operate in SNR environments as low as 13dB at full capacity, and as low as - 13dB in rate adaptive mode.

Optimal capacity utilization through synchronization. In asynchronous CDMA systems, codes arriving at the receiver are unaligned. This causes mutual interference between the codes, which forces the use of lower order modulation schemes resulting in significantly reduced data capacity. S-CDMA minimizes mutual interference by ensuring that codes are synchronized with each other through ranging, power management and adaptive equalization. The process of ranging guarantees time alignment by ensuring all codes arrive at the receiver at the same time. Power management and adaptive equalization compensate for variables such as temperature and changes in network topology. These techniques allow S-CDMA to utilize higher order modulation schemes providing a capacity of 14 Mbps in a 5 MHz channel in both the upstream and downstream paths. This 14 Mbps capacity is divided into 144 data streams, each of which is represented by a unique S-CDMA spreading code.

Efficient bandwidth management for multiple levels of Quality of Service. The TeraComm system segments each 14 Mbps upstream and downstream channel into 128 user data streams and 16 management and control data streams. Separating user data from management and control ensures high channel efficiency under heavy channel loading. Each of the 128 user data streams has a continuous data payload capacity of 64 Kbps. The bandwidth manager software residing in the system headend allocates data streams to cable modems individually or in groups. Data streams can also be assigned on a permanent basis, or can be multiplexed among multiple modems based on a fairness algorithm in the bandwidth manager. This capability allows the TeraComm system to provide a variety of Quality of Service levels. Constant Bit Rate ("CBR") services can be provisioned in increments of 64 Kbps by continuous assignment of data streams to a TeraPro cable modem. As a result, services such as leased lines and T-1 circuits can be emulated. Unspecified Bit Rate ("UBR") services can be supported by allowing modems to contend for data streams on an "as requested" basis. Because all access requests and grants are communicated through management streams, the impact on channel efficiency is minimized as more modems contend for bandwidth. Both CBR and UBR services can co-exist on a single channel enabling a cable operator to create multiple service levels and maximize revenue from the available bandwidth capacity.

CURRENT PRODUCTS

The Company's TeraComm system enables cable operators to cost-effectively deploy reliable two-way broadband access services. The TeraComm system is comprised of the TeraPro cable modem, the TeraLink 1000 Master Controller, the TeraLink Gateway and the TeraView Element Management and Provisioning Software.

The following diagram illustrates the TeraComm system:

[Diagram of the components of the TeraComm system]

THE TERACOMM SYSTEM

TeraPro Cable Modem. The TeraPro cable modem is a data communications device installed in a subscriber's home or business. The TeraPro cable modem connects to the subscriber's PC via a standard 10BaseT Ethernet connector and to the cable network via a standard coaxial cable connector. The TeraPro cable modem automatically configures itself without user intervention, thus minimizing modem installation time. In addition, the configuration software for the TeraPro cable modem is downloaded remotely, allowing centralized software upgrades directly from the headend management system.

The TeraPro cable modem delivers full two-way communication over the cable network, with data rates of up to 14 Mbps per 5 MHz channel in both the upstream and the downstream direction. The TeraPro cable modem operates at full capacity at an SNR as low as 13 dB, and gradually adjusts throughput to provide transmission at an SNR as low as -13 dB. This feature will permit the TeraPro cable modem to operate across any portion of the 5 to 42 MHz upstream RF spectrum.

TeraLink 1000 Master Controller. The TeraLink 1000 Master Controller is a data channel controller and multiplexer located at the cable headend system or distribution hub. The TeraLink 1000 Master Controller provides control, management and data transport functions for TeraPro cable modems connected to the cable network. It offers dynamic bandwidth management, high-speed traffic concentration, access control to data networking resources, and data service quality and integrity.

39

The TeraLink 1000 Master Controller is a single channel, rack-mountable controller that supports up to 2,000 cable modems per channel. Additional TeraLink 1000 Master Controllers can be added to scale service as performance and subscriber needs grow. The TeraLink 1000 Master Controller, with the TeraLink Gateway, provides a 100 BaseT interface for direct connectivity to a private backbone or any vendor's router or switch. Alternatively, the TeraLink 1000 Master Controller, with its built-in ATM OC-3 interface, can be connected via an ATM switch, or directly to Cisco's 7500 series routers.

TeraLink Gateway. The TeraLink Gateway is a rack-mountable edge concentrator providing end-user clients with broadband access to a remote IP backbone (e.g., Internet) as well as efficient communication between modems. The TeraLink Gateway includes an ATM OC-3 interface for connectivity to up to two TeraLink 1000 Master Controllers or an ATM switch. It also provides a 10/100 BaseT Ethernet/Fast Ethernet auto-sense interface to a headend backbone or any IP router including the Cisco Universal Broadband Router. The TeraLink Gateway also includes a separate 10 BaseT interface, which may be connected to a separate management network or the headend network. The TeraLink Gateway supports up to 2,000 cable modems per RF channel when connected to a TeraLink 1000 Master Controller. When used with the TeraLink Gateway, the TeraPro cable modems behave as an extension of the TeraLink Gateway, providing maximum bandwidth and privacy.

TeraView Element Management and Provisioning Software. The TeraView Element Management and Provisioning Software is a Windows 95 and Windows NT standards- based software application installed at the headend system or the network operations center. The TeraView software allows cable operators to configure, control, monitor and maintain multiple channels of the TeraComm system.

PRODUCTS UNDER DEVELOPMENT

Universal Cable Modem and TeraLink 2000 Master Controller. The Company currently is designing and developing a next-generation system, which includes the UCM and an accompanying headend controller, the TeraLink 2000 Master Controller. The UCM and the TeraLink 2000 Master Controller will be designed to be fully compliant with DOCSIS standards, while also offering additional features and performance enabled by the use of the S-CDMA technology. The UCM and the TeraLink 2000 Master Controller are in the early stages of development and the Company does not anticipate commercial deployment of these products until 1999.

The UCM will be designed to operate in any of three modes: (i) as an existing TeraPro cable modem to ensure backward compatibility for existing TeraComm system users; (ii) as a DOCSIS-compliant modem that will be compatible with multiple vendors' DOCSIS-compliant systems; and (iii) as an advanced system. In the advanced mode the UCM will be designed to offer DOCSIS-compliant 64/256 QAM modulation downstream channels, coupled with an advanced S-CDMA upstream channel, offering up to 40 Mbps downstream channel capacity and 30 Mbps upstream channel capacity.

CUSTOMERS

The Company markets its products to cable operators that seek to provide broadband access services to both residential and commercial end users. The Company's initial target market consists of the ten largest cable companies in each major geographic area. In most markets, a small number of large cable operators often provide services to a majority of subscribers in a specific region and thus influence the purchasing decisions of smaller cable operators. In the United States, ten cable operators together own and operate facilities passing approximately 74% of total homes passed. The Company commenced volume shipments of its products in the first quarter of 1998. To date, three of the largest North American cable operators are deploying the TeraComm system commercially.

40

Selected examples of the range of customers and applications for which the TeraComm system is being commercially deployed are as follows:

Cablevision. Cablevision is the fifth largest cable operator in the United States, with cable infrastructure passing approximately 5.1 million homes, primarily located in New York, New Jersey, Connecticut, Ohio and Massachusetts. Cablevision is currently deploying Terayon's products in systems located in Long Island, New York and areas of Connecticut for its optimum high speed data service.

Shaw Cable. Shaw is the third largest cable operator in Canada, with cable infrastructure passing approximately 2.0 million homes. Shaw currently has the largest cable modem deployment in Canada, with over 35,000 cable modem users. Shaw has selected Terayon to supply cable modem systems for Shaw's @Home service deployments in Victoria, British Columbia, Edmonton, Alberta and parts of metropolitan Toronto, Ontario.

Sumitomo. The Company has a distribution agreement with Sumitomo under which Crossbeam is distributing the TeraComm system to three of Japan's leading cable operators. The TeraComm system's noise resistant properties are designed to enable two-way broadband access over pure coaxial networks, which comprise the majority of Japan's cable infrastructure.

TCA Cable TV, Inc. TCA is the 16th largest cable operator in the United States, with cable infrastructure passing approximately 1.2 million homes, primarily in Texas, Arkansas and Louisiana. TCA has deployed the TeraComm system in Bryan/College Station, Texas and Amarillo, Texas. TCA provides a tiered service offering, with prices ranging from $49.95 per month for residential Internet access to $175 per month for commercial Internet access. TCA has announced that it intends to leverage the noise resistant properties of Terayon's products to deploy broadband access services on a pure coaxial network in Tyler, Texas.

Three customers accounted for approximately 73% of the Company's revenues in 1997 and for approximately 64% of the Company's revenues in the first six months of 1998. In 1997, sales to Telegate, Sumitomo and NET Brasil represented approximately 30%, 29% and 14%, respectively, of the Company's revenues. In the first six months of 1998, sales to Shaw, Sumitomo and Cablevision represented approximately 40%, 14% and 10%, respectively, of the Company's revenues. The Company believes that a substantial majority of its revenues will continue to be derived from sales to a relatively small number of customers for the foreseeable future. In addition, the Company believes that sales to these customers will be focused on a small number of projects. See "Risk Factors--Dependence on Small Number of Customers."

RESEARCH AND DEVELOPMENT

The Company believes that its future success will depend upon its ability to enhance its existing products and to develop and introduce new products that meet a wide range of evolving cable operator and end user needs. In addition, to address competitive and pricing pressures, the Company expects that it will have to reduce the unit cost of manufacturing its cable modems through design and engineering changes. For example, the Company has developed and intends to introduce a single-board modem by the end of 1998, which the Company anticipates will provide cost savings over its current dual-board modem. There can be no assurance that the Company will be successful in redesigning its products, that any such redesign will be made on a timely basis and without introducing significant errors and product defects, or that any such redesign, including the single-board modem, would result in sufficient cost reductions to allow the Company to significantly reduce the list price of its products or improve its gross margin.

The Company also currently is designing and developing a next-generation system, which includes the UCM and an accompanying headend controller, the TeraLink 2000 Master Controller. The UCM and the TeraLink 2000 Master Controller will be designed to be fully compliant with emerging DOCSIS standards, while also offering additional features and performance enabled by the use of the S-CDMA technology. The UCM and the TeraLink 2000 Master Controller are in the early stages of development and the

41

Company does not anticipate commercial deployment of these products until 1999. See "Risk Factors--Evolving Market; Rapid Technological Change; Market Acceptance of S-CDMA," "--Ability to Achieve Cost Reductions," "--Evolving Industry Standards" and "--Dependence on Products Under Development."

As of June 30, 1998, the Company had 51 employees engaged in research and development. The Company's total research and development expenses for 1995, 1996 and 1997 and the first six months of 1998 were $2.0 million, $8.0 million, $11.3 million and $4.9 million, respectively.

SALES AND MARKETING

Terayon has direct sales forces in North America, Latin America and Europe. The Company also distributes its products via distributors and systems integrators. Terayon has signed a distribution agreement with Sumitomo under which Crossbeam is distributing the TeraComm system to three of Japan's leading cable operators.

The Company markets its products directly to cable operators through its sales force, key distribution and technology partners, as well as other marketing vehicles such as industry press, trade shows and the World Wide Web. Through its marketing efforts, the Company strives to educate cable operators on the technological and business benefits of its system solution, as well as the Company's ability to provide quality support and service to the customer. Terayon participates in the major trade shows and industry events for the cable industry in the United States and is expanding its presence in other markets through joint participation at local events with its international sales and marketing partners. Industry referrals and reference accounts are significant marketing tools developed and utilized by the Company.

CUSTOMER SERVICE AND TECHNICAL SUPPORT

The Company believes that its ability to consistently provide high quality service and support will be a key factor in attracting and retaining customers. The Technical Services and Support ("TSS") organization provides support 24 hours a day, seven days per week. Prior to deployment of the Company's systems, each cable operator's needs are assessed and proactive solutions are implemented, including various levels of training, periodic management and coordination meetings, and problem escalation procedures. Terayon places a strong emphasis on technical training, both for cable operators and systems integrators. Initial training is offered to cable operators and systems integrators at no cost, both in Terayon's headquarters in Santa Clara and on a cable operator's or system integrator's premises. At June 30, 1998, the TSS organization consisted of 13 employees located in North America, Europe, Latin America and Asia.

In addition, Terayon has developed sophisticated tools for remote diagnosis and monitoring of the TeraComm systems deployed by cable operators. Such tools enable the Company to monitor cable operators' installations of the TeraLink 1000 Master Controller and to proactively suggest solutions before problems become noticeable to end users. The Company is developing a Web-based knowledge system to provide cable operators with access to the latest technical support information.

MANUFACTURING

The Company outsources the materials procurement, printed circuit board assembly, and product assembly and testing to turnkey contract manufacturers. Currently, the Company contracts with Solectron, located in Milpitas, California, for the manufacture of the majority of its products. CMC, located in Santa Clara, California, also manufactures certain of the Company's products. The Company has a limited in-house manufacturing capability at its headquarters in Santa Clara. This facility is currently used for the assembly and final testing of TeraLink 1000 Master Controller and TeraLink Gateways, pilot production of new modem designs, sample testing of products received from volume modem manufacturers, developing the manufacturing process and documentation for new products in preparation for outsourcing. The Company also repairs products returned from customers with its in-house manufacturing resources.

The Company's future success will depend in significant part on its ability to obtain high volume manufacturing at low costs. As volume increases, the Company plans to engage additional contract

42

manufacturers, to procure additional manufacturing facilities and equipment, to modify existing inventory procedures, to substantially increase its personnel and to revise its quality assurance and testing practices. There can be no assurance that any of these efforts will be successful. The Company anticipates that the need to reduce the manufacturing costs of its cable modem and will continue to evaluate the use of low cost third-party suppliers and manufacturers. See "Risk Factors--Ability to Achieve Cost Reductions" and "-- Limited Manufacturing Experience and Dependence on Contract Manufacturer."

Subcontractors supply the Company's contract manufacturers with both standard components and subassemblies manufactured to the Company's specifications. The Company is dependent upon certain key suppliers for a number of the components for its products. For example, the Company currently relies on VLSI for the Company's S-CDMA ASIC, which is used in the Company's headend and cable modem products. In addition, all of the Company's products contain one or more components that are currently only available from a single source.

COMPETITION

The market for broadband access systems is extremely competitive and is characterized by rapid technological change. The Company's direct competitors in the cable modem arena include Bay Networks, Com21, Hayes, Hybrid, Matsushita, Motorola, Phasecom, RCA, Samsung, Scientific-Atlanta, Sony, 3Com, Toshiba and Zenith and there are many other potential market entrants. In addition, Bay Networks, Com21, Hybrid and Motorola introduced cable modems prior to the Company, and have established relationships and have worked with customers for a longer period of time than the Company. The principal competitive factors in this market include: product performance, features and reliability; price; size and stability of operations; breadth of product line; sales and distribution capability; technical support and service; relationships with cable operators; standards compliance; and general industry and economic conditions. Certain of these factors are outside of the Company's control. The existing conditions in the broadband access market could change rapidly and significantly as a result of technological changes, and the development and market acceptance of alternative technologies could decrease the demand for the Company's products or render them obsolete. There can be no assurance that these companies and other competitors will not introduce broadband access products that will be less costly or provide superior performance or achieve greater market acceptance than the Company's products.

The Company sells products that also compete with existing data access and transmission systems utilizing the telecommunications networks, such as those of 3Com. Additionally, the Company's controller and headend system products face intense competition from well-established companies such as Bay Networks, Cisco and 3Com. Many of the Company's current and potential competitors have significantly greater financial, technical, marketing, distribution, customer support and other resources, as well as greater name recognition and access to customers than the Company. There can be no assurance that the Company will be able to compete successfully against current or future competitors or that the competitive pressures faced by the Company will not have a material adverse effect on its business, operating results and financial condition.

The market for cable modems may be impacted by the development of other technologies that enable the provisioning of broadband access services. Examples of such technologies include technologies that increase the efficiency of digital transmission over telephone companies' existing copper infrastructure, such as various xDSL, as well as ISDN. Similarly, broadband access services may be deployed over a number of other media, including fiber optic cable, DBS and other wireless technologies. Broadband access services based on some of these competing technologies are already available and could materially limit acceptance of cable modem-based services. The failure of broadband access services based on cable modem technology to gain widespread commercial acceptance by cable operators and end users of broadband access services would have a material adverse effect on the Company's business, operating results and financial condition. See "Risk Factors -- Highly Competitive Industry; Established Competitors."

43

REGULATION

The Company and its customers are subject to varying degrees of federal, state and local regulation. The jurisdiction of the FCC extends to the communications industry, including broadband access products such as those of the Company. The FCC has promulgated regulations that, among other things, set installation and equipment standards for communications systems. Although FCC regulations and other governmental regulations have not materially restricted the Company's operations, there can be no assurance that future regulations adopted by the FCC or other regulatory bodies will not have a material adverse effect on the Company. Further, regulation of the Company's customers may adversely impact the Company's business, operating results and financial condition. For example, FCC regulatory policies affecting the availability of cable services and other terms on which cable companies conduct their business, may impede the Company's penetration of certain markets. In addition, regulation of cable television rates may affect the speed at which cable operators upgrade their cable infrastructures to two-way HFC. Changes in, or the failure by the Company to comply with, applicable domestic and international regulations could have a material adverse effect on the Company's business, operating results and financial condition. In addition, the increasing demand for communications systems has exerted pressure on regulatory bodies worldwide to adopt new standards for such products and services, generally following extensive investigation of and deliberation over competing technologies. The delays inherent in this governmental approval process have in the past, and may in the future, cause the cancellation, postponement or rescheduling of the installation of communications systems by the Company's customers, which in turn may have a material adverse effect on the sale of products by the Company to such customers. For example, the Company experienced delays in product shipments to a customer in Brazil due to delays in certain regulatory approvals in Brazil, and there can be no assurance that similar delays will not occur in other countries in which the Company markets or plans to market its products. In addition, the Company's customers in certain parts of Asia, such as Japan, are required to obtain licenses prior to selling the Company's products, and delays in obtaining such licenses could have an adverse impact on the Company's operating results. See "Risk Factors -- Regulation of the Communications Industry."

In the United States, in addition to complying with FCC regulations, the Company's products will be required to meet certain safety requirements. For example, the Company will be required to have its products certified by UL in order to meet federal requirements relating to electrical appliances to be used inside the home. Outside of the United States, the Company's products will be subject the regulatory requirements of each country in which the products are manufactured or sold. These requirements are likely to vary widely, and there can be no assurance that the Company will be able to obtain on a timely basis or at all such regulatory approvals as may be required for the manufacture, marketing or sale of its products. Any delay in or failure to obtain such approvals or meet such requirements could have a material adverse effect on the Company's business, operating results and financial condition. See "Risk Factors -- Other Regulatory Approvals or Certifications."

INTELLECTUAL PROPERTY

The Company relies on a combination of patent, trade secret, copyright and trademark laws and contractual restrictions to establish and protect proprietary rights in its products. The Company has two issued patents and five patent applications pending in the United States. The Company has seven patent applications pending internationally. There can be no assurance that the Company's patent applications will be granted or, if granted, that the claims covered by the patents will not be reduced from those included in the Company's applications. Any patent might be subject to challenge in court and, whether or not challenged, might not be sufficiently broad to prevent third parties from developing equivalent technologies or products. The Company has entered into confidentiality and invention assignment agreements with its employees, and enters into non-disclosure agreements with certain of its suppliers, distributors and appropriate customers so as to limit access to and disclosure of its proprietary information. There can be no assurance that these statutory and contractual arrangements will prove

44

sufficient to prevent misappropriation of the Company's technology or to deter independent third-party development of similar technologies.

The Company pursues the registration of its trademarks in the United States and has applications pending to register several of its trademarks. However, since the laws of certain foreign countries might not protect the Company's products or intellectual property rights to the same extent as do the laws of the United States, effective trademark, copyright, trade secret and patent protection might not be available in every country in which the Company's products might be manufactured, marketed or sold.

The Company expects that developers of cable modems will increasingly be subject to infringement claims as the number of products and competitors in the Company's industry segment grows. The Company has received a letter from an individual claiming that the Company's technology infringes a patent held by such individual. The Company has reviewed the allegations made by such individual and, after consulting with its patent counsel, does not believe that the Company's technology infringes any valid claim of such individual's patent. There can be no assurance that, if the issue were to be submitted to a court, such a court would not find that the Company's products infringe the patent, nor that the individual will not continue to assert infringement. If the Company is found to have infringed such individual's patent, the Company could be subject to substantial damages and/or an injunction preventing it from conducting its proposed business, and the Company's business could be materially and adversely affected. In addition, there can be no assurance that other third parties will not assert infringement claims against the Company in the future. Any such claim, whether meritorious or not, could be time- consuming, result in costly litigation, cause product shipment delays or require the Company to enter into royalty or licensing agreements. Such royalty or licensing agreements may not be available on terms acceptable to the Company or at all, which could have a material adverse effect upon the Company's business, operating results and financial condition. Litigation also may be necessary to enforce the Company's intellectual property rights. Any infringement claim or other litigation against or by the Company could have a material adverse effect on the Company's business, operating results and financial condition.

EMPLOYEES

As of June 30, 1998, Terayon had 106 employees, of which 51 were in the engineering group, 27 were in marketing, sales and customer support, 15 were in operations and 13 were in general and administrative functions. None of the Company's employees is represented by a union. The Company believes that its relations with its employees are good.

PROPERTIES

The Company leases an approximately 30,000 square foot facility located in Santa Clara, California and has an option to lease approximately 10,000 additional square feet in August 1998. The current lease for the Santa Clara facility expires in March 2002. The Company has sales offices in Denver, Colorado; Atlanta, Georgia; Sao Paulo, Brazil; and Brussels, Belgium. The Company believes that its existing facilities are adequate to meet its needs for the immediate future and that future growth can be accommodated by leasing additional or alternative space near its current facilities.

LEGAL PROCEEDINGS

The Company is not currently a party to any material legal proceedings.

(1) Options generally vest at a rate 20% on the first anniversary of the vesting commencement date and 1/48th each month thereafter. The term of each option granted is generally the earlier of (i) ten years or (ii) 90 days after termination of the optionee's services to the Company. Options are immediately exercisable; however, the unvested shares purchasable under such options are subject to repurchase by the Company at the original exercise price paid per share upon the optionee's cessation of service prior to the vesting of such shares.
(2) Based on an aggregate of 1,304,050 options granted to employees, consultants and directors, including the Named Executive Officers, of the Company during the fiscal year ended December 31, 1997.
(3) The exercise price per share of each option was equal to the fair market value of the Common Stock on the date of grant as determined by the Board of Directors.
(4) The potential realizable value is calculated based on the term of the option at its time of grant (ten years). It is calculated assuming that the fair market value of the Company's Common Stock on the date of grant appreciates at the indicated annual rate compounded annually for the entire term of the option and that the option is exercised and sold on the last day of its term for the appreciated stock price.

AGGREGATE OPTION EXERCISES IN FISCAL 1997 AND DECEMBER 31, 1997 OPTION VALUES

There were no exercises of options by any Named Executive Officer in the fiscal year ended December 31, 1997.

EMPLOYEE BENEFIT PLANS

1997 Equity Incentive Plan. The Company's 1997 Equity Incentive Plan (the "1997 Plan") was adopted in March 1997 and amended in December 1997 and June 1998. An aggregate of 3,300,000 shares of Common Stock currently are authorized for issuance under the 1997 Plan. However, each year on January 1, starting with January 1, 1999, the aggregate number of shares of Common Stock that are available for issuance under the 1997 Plan will automatically be increased to that number of shares of Common Stock that is equal to 5% of the Company's outstanding shares of Common Stock on such date.

The 1997 Plan provides for the grant of incentive stock options, as defined under the Internal Revenue Code of 1986, as amended (the "Code"), to employees (including officers and employee directors) and non-statutory stock options, restricted stock purchase awards and stock bonuses to employees (including officers and employee directors), directors and consultants of the Company and its affiliates. The 1997 Plan is administered by the Compensation Committee, which determines the recipients and types of awards to be granted, including the exercise price, number of shares subject to the award and the exercisability thereof.

51

The terms of options granted under the 1997 Plan may not exceed 10 years. The Compensation Committee determines the exercise price of options granted under the 1997 Plan. However, the exercise price for an incentive stock option cannot be less than 100% of the fair market value of the Common Stock on the date of the option grant, and the exercise price for a non-statutory stock option cannot be less than 85% of the fair market value of the Common Stock on the date of the option grant. Options granted under the 1997 Plan vest at the rate specified in the option agreement. Generally, the right to exercise 20% of the total number of shares granted vest 12 months after the date of option grant, with the reminder vesting monthly over four years thereafter, such that an option is fully vested on the fifth anniversary of the date of the option grant. Generally, the optionee may not transfer a stock option other than by will or the laws of descent or distribution. However, an optionee may designate a beneficiary who may exercise the option in the event of the optionee's death or disability. Unless the terms of an optionee's option agreement provide for an earlier termination, in the event of the optionee's cessation of his or her relationship with the Company due to death or disability, the optionee's beneficiary may exercise any vested options up to 18 months and 12 months, respectively, after the date of such cessation. If such optionee's relationship with the Company ceases for any reason other than the optionee's death or disability, the optionee may exercise any vested options during the 30 days following such cessation.

No incentive stock option (and, prior to the Company's stock being publicly traded, no non-statutory stock option) may be granted to any person who, at the time of the grant, owns (or is deemed to own) stock possessing more than 10% of the total combined voting power of the Company or any affiliate of the Company, unless the option exercise price is at lease 110% of the fair market value of the stock subject to the option on the date of grant and the term of the option does not exceed five years from the date of the grant. In addition, the aggregate fair market value, determined at the time of grant, of the shares of Common Stock with respect to which incentive stock options are exercisable for the first time by an optionee during any calendar year (under the 1997 Plan and all other stock plans of the Company and its affiliates) may not exceed $100,000.

When the Company becomes subject to Section 162(m) of the Code (which denies a deduction to publicly held corporations for certain compensation paid to specified employees in a taxable year to the extent that the compensation exceeds $1,000,000), no person may be granted options under the Incentive Plan covering more than 500,000 shares of Common Stock in any calendar year.

Shares subject to stock awards that have expired or otherwise terminated without having been exercised in full again become available for the grant of awards under the 1997 Plan. The Compensation Committee has the authority to reprice outstanding options or to offer optionees the opportunity to replace outstanding options with new options for the same or a different number of shares. Both the original and new options will count toward the Code Section 162(m) limitations set forth above.

Restricted stock purchase awards granted under the 1997 Plan may be granted pursuant to a repurchase option in favor of the Company in accordance with a vesting schedule and at a price determined by the Compensation Committee. Stock bonuses may be awarded in consideration of past services without a purchase payment. Rights under a stock bonus or restricted stock bonus agreement generally may not be transferred other than by will or the laws of descent and distribution during such period as the stock awarded pursuant to such an agreement remains subject to the agreement.

If there is any sale of all or substantially all of the Company's assets, any merger or any consolidation in which the Company is not the surviving corporation or a like transaction involving the Company, all outstanding awards under the 1997 Plan either will be assumed or substituted for by any surviving entity. If the surviving entity determines not to assume or substitute for such awards, the vesting of stock awards held by persons still serving the Company or its affiliate will be accelerated and such awards will terminate if not exercised prior to the sale of assets, merger or consolidation.

52

As of June 30, 1998, 39,250 shares of Common Stock had been issued upon the exercise of options granted under the 1997 Plan, options to purchase 1,010,560 shares of Common Stock were outstanding and 2,250,190 shares remained available for future grant. The 1997 Plan will terminate in March 2007 unless terminated by the Board before then. As of June 30, 1998, no stock awards or restricted stock had been granted under the 1997 Plan.

1995 Stock Option Plan. The Company also has a 1995 Stock Option Plan (the "1995 Plan"). The 1995 Plan is administered by the Board, unless the Board delegates administration to a committee comprised of members of the Board. Under the 1995 Plan, stock options and awards may be granted to employees, directors and consultants. Only employees may receive incentive stock options; employees, directors and consultants may receive non-statutory stock options and stock awards other than incentive stock options. The exercise price of incentive stock options granted under the 1995 Plan must be at least equal to the fair market value of the Common Stock on the date of grant, while the exercise price of nonstatutory options must equal at least 85% of such market value. Generally, the right to exercise 20% of the total number of shares granted vest 12 months after the date of option grant, with the reminder vesting monthly over four years thereafter, such that an option is fully vested on the fifth anniversary of the date of the option grant. Options and awards granted under the Plan must be exercised within ten years of the date of grant. The other terms of the 1995 Plan are substantially similar to the terms of the 1997 Plan.

As of June 30, 1998, 778,268 shares had been issued upon the exercise of options under the 1995 Plan, 1,332,732 shares of Common Stock were subject to outstanding options and 3,747 shares remained available for future grant. The 1995 Plan will terminate in March 2005 unless terminated by the Board of Directors before then.

1998 Non-Employee Directors' Stock Option Plan. In June 1998, the Board adopted the Directors' Plan to provide for the automatic grant of options to purchase shares of Common Stock to non-employee directors of the Company who are not employees of or consultants to the Company or of any affiliate of the Company (a "Non-Employee Director"). The Directors' Plan is administered by the Board, unless the Board delegates administration to a Committee comprised of members of the Board.

The aggregate number of shares of Common Stock that may be issued pursuant to options granted under the Directors' Plan is 200,000 shares. Pursuant to the terms of the Directors' Plan, after the effective date of the initial public offering of the Company's Common Stock, each person who is elected or appointed for the first time to be a Non-Employee Director automatically shall, upon the date of his or her initial election or appointment to be a Non-Employee Director by the Board or stockholders of the Company, be granted an option to purchase 30,000 shares of Common Stock. In addition, on the day following each Annual Meeting of Stockholders of the Company ("Annual Meeting"), commencing with the Annual Meeting in 1999, each person who is then serving as a Non-Employee Director automatically shall be granted an option to purchase 12,500 shares of Common Stock, which amount shall be prorated for any Non-Employee Director who has not continuously served as a Non-Employee Director for the 12-month period prior to the date of such Annual Meeting. In addition, on the day following each Annual Meeting, commencing with the Annual Meeting in 1999, each Non-Employee Director who is then serving as a member of a committee of the Board of Directors automatically shall be granted, for each such committee, an option to purchase 3,000 shares of Common Stock of the Company, which amount shall be prorated for any Non-Employee Director who has not continuously served as a member of such committee for the 12-month period prior to the date of such Annual Meeting.

The exercise price of the options granted under the Directors' Plan will be equal to the fair market value of the Common Stock on the date of grant. No option granted under the Directors' Plan may be exercised after the expiration of 10 years from the date it was granted. Options granted under the Directors' Plan vest and become exercisable as to 33% of the shares on the first anniversary of the date

53

of grant and 1/36th of the shares monthly thereafter. Options granted under the Directors' Plan generally are non-transferable. However, an optionee may designate a beneficiary who may exercise the option following the optionee's death. An optionee whose service relationship with the Company or any affiliate (whether as a Non-Employee Director of the Company or subsequently as an employee, director or consultant of either the Company or an affiliate) ceases for any reason may exercise vested options for the term provided in the option agreement (3 months generally, 12 months in the event of disability, and 18 months in the event of death).

In the event of certain changes in control of the Company, all outstanding awards under the Directors' Plan either will be assumed or substituted for by any surviving entity. If the surviving entity determines not to assume or substitute for such awards, the vesting and time during which such options may be exercised shall be accelerated prior to such event and the options will terminate if not exercised after such acceleration and at or prior to such event. Unless terminated sooner by the Board of Directors, the Directors' Plan will terminate in June 2008.

1998 Employee Stock Purchase Plan. In June 1998, the Company's Board of Directors approved the 1998 Employee Stock Purchase Plan (the "Purchase Plan"), covering an aggregate of 700,000 shares of Common Stock. The Purchase Plan is intended to qualify as an employee stock purchase plan within the meaning of Section 423 of the Code. Under the Purchase Plan, the Board of Directors may authorize participation by eligible employees, including officers, in periodic offerings following the adoption of the Purchase Plan. The offering period for any offering will be no more than 27 months.

Under the Purchase Plan, employees are eligible to participate if they are employed by the Company or an affiliate of the Company designated by the Board of Directors and are employed at least 20 hours per week and five months per year. Employees who participate in an offering will have the right to purchase up to the number of shares of Common Stock purchasable with a percentage designated by the Board of Directors, up to 15%, of an employee's earnings withheld pursuant to the Purchase Plan and applied, on specified dates determined by the Board of Directors, to the purchase of shares of Common Stock. The price of Common Stock purchased under the Purchase Plan will be equal to 85% of the lower of the fair market value of the Common Stock on the commencement date of each offering period or the relevant purchase date. Employees may end their participation in the offering at any time during the offering period, and participation ends automatically on termination of employment with the Company.

In the event of certain changes in control of the Company, the Company and the Board of Directors have discretion to provide that each right to purchase Common Stock will be assumed or an equivalent right will be substituted by the successor corporation, or the Board may shorten the offering period and provide for all sums collected by payroll deductions to be applied to purchase stock immediately prior to the change in control. The Purchase Plan will terminate at the Board's discretion or when all of the shares reserved for issuance under the Purchase Plan have been issued.

401(k) Plan. The Company maintains the Terayon Corporation 401(k) Retirement Plan (the "401(k) Plan") for eligible employees ("Participants"). A Participant may contribute up to 15% of his or her total annual compensation to the 401(k) Plan, or up to a statutorily prescribed annual limit, if less. The annual limit for 1998 is $10,000. Each Participant is fully vested in his or her deferred salary contributions. Participant contributions are held and invested by the 401(k) Plan's trustee. The Company may make discretionary contributions as a percentage of Participant contributions, subject to established limits. To date, the Company has not made any contributions to the
401(k) Plan on behalf of the Participants. The 401(k) Plan is intended to qualify under Section 401 of the Code, so that contributions by employees or by the Company to the 401(k) Plan, and income earned on the 401(k) Plan contributions, are not taxable to employees until withdrawn from the 401(k) Plan, and so that contributions by the Company, if any, will be deductible by the Company when made.

Mr. Rakib is the brother of Zaki Rakib, the Company's Chief Executive Officer and a director of the Company. See "Management --Employment Agreements."

In December 1995, in connection with the purchase by Cisco of Series B Preferred Stock of the Company, the Company granted Cisco a right of first offer to acquire the Company in the event the Company commences a sale of 50% or more of its outstanding capital stock or all of its assets. The Company also granted Cisco the right to make an offer to purchase the Company in the event the Company commences an initial public offering of its securities. Cisco holds more than 5% of the outstanding equity of the Company. Cisco also has the right to elect one director to the Company's Board of Directors. Cisco's rights terminate upon the completion of the Company's initial public offering.

In March 1996, the Company loaned Shlomo Rakib, the Company's Chairman of the Board, President and Chief Technical Officer, $100,000 pursuant to an interest- free promissory note, with the principal amount due in March 2001. The note (i) may be extended for a longer term at the option of the Company, (ii) is secured by 20,000 shares of Common Stock held by Mr. Rakib and (iii) will accelerate upon termination of his employment with the Company, the initial public offering of the Company's securities or the sale of the Company.

In December 1997, the Company entered into a strategic partnership and distributorship agreement with Sumitomo, a greater than 5% stockholder of the Company, whereby Sumitomo and the Company formed a strategic partner relationship for the purpose of promoting the Company's products in Japan. Pursuant to this agreement, the Company appointed Sumitomo as its exclusive distributor for the Company's products in Japan and as a non-exclusive distributor for the Company's products in the rest of the world. Sales to Sumitomo in the first six months of 1998 were approximately $1.3 million, which represented approximately 14% of the Company's revenues for such period.

The Company has granted options to certain of its directors and executive officers. See "Management -- Director Compensation."

The Company believes that the terms of the transactions described above were no less favorable to the Company than would have been obtained from an unaffiliated third party. Any future transactions between the Company and any of its officers, directors or principal stockholders will be on terms no less favorable to the Company than could be obtained from unaffiliated third parties and will be approved by a majority of the independent and disinterested members of the Board of Directors.

The Company intends to enter into indemnification agreements with its directors and executive officers for the indemnification of and advancement of expenses to such persons to the full extent permitted by law. The Company also intends to execute such agreements with its future directors and executive officers. See "Management -- Limitation on Directors' and Officers' Liability."

DESCRIPTION OF CAPITAL STOCK

Upon the completion of this offering, the authorized capital stock of the Company will consist of 30,000,000 shares of Common Stock, par value $0.001 per share, and 5,000,000 shares of Preferred Stock, par value $0.001 per share ("Preferred Stock").

COMMON STOCK

As of June 30, 1998, there were 13,220,733 shares of Common Stock (including shares of Preferred Stock that will be converted into Common Stock upon completion of this offering) outstanding held of record by 102 stockholders.

The holders of Common Stock are entitled to one vote for each share held of record on all matters submitted to a vote of the stockholders. Subject to preferences that may be applicable to any outstanding shares of the Preferred Stock, the holders of Common Stock are entitled to receive ratably such dividends as may be declared by the Board of Directors out of funds legally available therefor. See "Dividend Policy." In the event of a liquidation, dissolution or winding up of the Company, holders of the Common Stock are entitled to share ratably in all assets remaining after payment of liabilities and the liquidation preferences of any outstanding shares of Preferred Stock. Holders of Common Stock have no preemptive rights and no right to convert their Common Stock into any other securities. There are no redemption or sinking fund provisions applicable to the Common Stock. All outstanding shares of Common Stock are, and all shares of Common Stock to be outstanding upon the completion of this offering will be, fully paid and non-assessable.

PREFERRED STOCK

Pursuant to the Restated Certificate, the Board of Directors has the authority, without further action by the stockholders, to issue up to 5,000,000 shares of Preferred Stock in one or more series and to fix the designations, powers, preferences, privileges and relative participating, optional or special rights and the qualifications, limitations or restrictions thereof, including dividend rights, conversion rights, voting rights, terms of redemption and liquidation preferences, any or all of which may be greater than the rights of the Common Stock. The Board of Directors, without stockholder approval, can issue Preferred Stock with voting, conversion or other rights that could adversely affect the voting power and other rights of the holders of Common Stock. Preferred Stock could thus be issued quickly with terms calculated to delay, defer or prevent a change in control of the Company or make removal of management more difficult. Additionally, the issuance of Preferred Stock may have the effect of decreasing the market price of the Common Stock and may adversely affect the voting and other rights of the holders of Common Stock. Upon the completion of this offering, there will be no shares of Preferred Stock outstanding and the Company has no current plans to issue any shares of the Preferred Stock.

WARRANTS

In April 1998, the Company issued to Shaw a warrant ("Product Purchase Warrant") to purchase 3,000,000 shares of Common Stock at an exercise price of $6.50 per share. The Product Purchase Warrant is exercisable between April 6, 2003 and December 31, 2003, or earlier depending on the volume of cable modem purchases by Shaw in 1998, 1999 and 2000. In addition, the Company issued to Shaw a warrant ("Anti-Dilution Warrant") to purchase an indeterminate number of shares of Common Stock for an aggregate price of $1.00. The Anti-Dilution Warrant is exercisable from time to time when the Company issues certain new equity securities until the date upon which Shaw ceases to own at least 384,615 shares of Common Stock.

59

REGISTRATION RIGHTS

Pursuant to an agreement between the Company and the holders (or their permitted transferees) of approximately 8,200,635 shares of Common Stock and Preferred Stock (which Preferred Stock will automatically be converted into Common Stock upon the completion of this offering) and of warrants to purchase 3,038,462 shares of Common Stock ("Holders"), the Holders will be entitled to certain rights with respect to registration of such shares for sale in the public market. The Holders are entitled to certain rights with respect to the registration of such shares under the Securities Act. If the Company proposes to register its Common Stock, subject to certain exceptions, under the Securities Act, the Holders are entitled to notice of the registration and are entitled at the Company's expense to include such shares therein, provided that the managing underwriters have the right to limit the number of such shares included in the registration or exclude such shares entirely. In addition, certain of the Holders may require the Company, at the Company's expense, on no more than six occasions, to file a registration statement under the Securities Act with respect to their shares of Common Stock. Such rights may not be exercised until six months after the completion of this offering. Further, certain Holders may require the Company at the Company's expense on no more than four occasions, to register all or portion of their shares on Form S-3 when such form becomes available to the Company, subject to certain conditions and limitations. Such rights expire on the seventh anniversary of completion of this offering.

ANTI-TAKEOVER EFFECTS OF PROVISIONS OF CHARTER DOCUMENTS AND DELAWARE LAW

Charter Documents

The Restated Certificate and Restated Bylaws include a number of provisions that may have the effect of deterring hostile takeovers or delaying or preventing changes in control or management of the Company. First, the Restated Certificate provides that all stockholder action upon completion of this offering must be effected at a duly called meeting of holders and not by a consent in writing. Second, the Restated Bylaws provide that special meetings of the holders may be called only by (i) the Chairman of the Board of Directors, (ii) the Chief Executive Officer or (iii) Board of Directors pursuant to a resolution adopted by a majority of the total number of authorized directors. Third, the Certificate and the Bylaws provide for a classified Board of Directors. The Certificate includes a provision requiring cumulative voting for directors only if required by applicable California law. Under cumulative voting, a minority stockholder holding a sufficient percentage of a class of shares may be able to ensure the election of one or more directors. As a result of the provisions of the Certificate and applicable California and Delaware law, at any annual meeting whereby the Company had at least 800 stockholders as of the end of the fiscal year prior to the record date for such annual meeting, stockholders will not be able to cumulate votes for directors. Finally, the Restated Bylaws establish procedures, including advance notice procedures with regard to the nomination of candidates for election as directors and stockholder proposals. These provisions of the Restated Certificate and Restated Bylaws could discourage potential acquisition proposals and could delay or prevent a change in control or management of the Company. Such provisions also may have the effect of preventing changes in the management of the Company. See "Risk Factors--Anti-Takeover Provisions."

Delaware Takeover Statute

The Company is subject to the provisions of Section 203 of the Delaware General Corporation Law ("Section 203"). In general, Section 203 prohibits a publicly held Delaware corporation, such as the Company shall become upon completion of this offering, from engaging in a "business combination" with an "interested stockholder" for a period of three years after the date of the transaction pursuant to which the person became an interested stockholder, unless the business combination is approved in a manner prescribed by Delaware law. For purposes of Section 203, a "business combination" includes a merger, asset sale or other transaction resulting in a financial benefit to the interested stockholder, and

60

an "interested stockholder" is a person who, together with affiliates and associates, owns (or within three years prior, did own) 15% or more of the corporation's voting stock.

TRANSFER AGENT AND REGISTRAR

Boston Equiserve has been appointed as the transfer agent and registrar for the Company's Common Stock.

61

SHARES ELIGIBLE FOR FUTURE SALE

Prior to this offering, there has been no market for the Common Stock of the Company, and there can be no assurance that a significant public market for the Common Stock will develop or be sustained after this offering. Future sales of substantial amounts of Common Stock (including shares issued upon exercise of outstanding options and warrants) in the public market following this offering could adversely affect market prices prevailing from time to time and could impair the Company's ability to raise capital through sale of its equity securities. As described below, no shares currently outstanding will be available for sale immediately after this offering because of certain contractual restrictions on resale. Sales of substantial amounts of Common Stock of the Company in the public market after the restrictions lapse could adversely affect the prevailing market price and the ability of the Company to raise equity capital in the future.

Upon completion of this offering, the Company will have outstanding 16,220,733 shares of Common Stock (based upon shares outstanding as of June 30, 1998), assuming no exercise of the Underwriters' over-allotment option and no exercise of outstanding options or warrants that do not expire prior to completion of this offering. Of these shares, the 3,000,000 shares sold in this offering will be freely tradable without restriction under the Securities Act except for any shares purchased by "affiliates" of the Company as that term is defined in Rule 144 under the Securities Act. The remaining 13,220,733 shares of Common Stock held by existing stockholders are "Restricted Shares" as that term is defined in Rule 144. All such Restricted Shares are subject to lock-up agreements providing that, with certain limited exceptions, the stockholder will not offer, sell, contract to sell or otherwise dispose of any Common Stock of the Company, including any securities that are convertible into or exchangeable for, Common Stock for a period 180 days after the date of this Prospectus without the prior written consent of BT Alex. Brown Incorporated or the Company. As a result of these lock-up agreements, notwithstanding possible earlier eligibility for sale under the provisions of Rules 144, 144(k) and 701, none of these shares will be salable until 181 days after the date of this Prospectus. Beginning 181 days after the date of this Prospectus, 12,091,022 Restricted Shares will be eligible for sale in the public market, subject to volume and other limitations under Rule 144. In addition, as of June 30, 1998, there were outstanding options to purchase 2,483,292 shares and warrants to purchase 3,088,462 shares. Of such options and warrants, 5,521,754 shares issuable upon exercise are subject to lock-up agreements. The Company has agreed with BT Alex. Brown Incorporated not to release any stockholder from any lock-up agreement between the Company and the stockholder without the prior written consent of BT Alex. Brown Incorporated. BT Alex. Brown Incorporated may, in its sole discretion and at any time without notice, release all or any portion of the securities subject to lock-up agreements.

In general, under Rule 144 as currently in effect, beginning 90 days after the date of this Prospectus, a person (or persons whose shares are aggregated) who has beneficially owned Restricted Shares for at least one year (including the holding period of any prior owner except an affiliate) would be entitled to sell within any three-month period a number of shares that does not exceed the greater of: (i) 1% of the number of shares of Common Stock then outstanding (which will equal approximately 162,207 shares immediately after this offering); or (ii) the average weekly trading volume of the Common Stock during the four calendar weeks preceding the filing of a Form 144 with respect to such sale. Sales under Rule 144 are also subject to certain manner of sale provisions and notice requirements and to the availability of current public information about the Company. Under Rule 144(k), a person who is not deemed to have been an affiliate of the Company at any time during the three months preceding a sale, and who has beneficially owned the shares proposed to be sold for at least two years (including the holding period of any prior owner except and affiliate), is entitled to sell such shares without complying with the manner of sale, public information, volume limitation or notice provisions of Rule 144.

Rule 701, as currently in effect, permits resales of shares in reliance upon Rule 144 but without compliance with certain restrictions, including the holding period requirement, of Rule 144. Any employee, officer or director of or consultant to the Company who purchased shares pursuant to a

62

written compensatory plan or contract may be entitled to rely on the resale provisions of Rule 701. Rule 701 permits affiliates to sell their Rule 701 shares under Rule 144 without complying with the holding period requirements of Rule 144. Rule 701 further provides that non-affiliates may sell such shares in reliance on Rule 144 without having to comply with the holding period, public information, volume limitation or notice provisions of Rule 144. All holders of Rule 701 shares are required to wait until 90 days after the date of this Prospectus before selling such shares. However, all Rule 701 shares are subject to lock-up agreements and will only become eligible for sale at the expiration of the 180-day lock-up agreements or no sooner than 90 days after the offering upon obtaining the prior written consent of BT Alex. Brown Incorporated.

Immediately after this offering, the Company intends to file a registration statement under the Securities Act covering shares of Common Stock subject to outstanding options under the 1995 Stock Option Plan, the 1997 Equity Incentive Plan, the 1998 Employee Stock Purchase Plan and the 1998 Non-employee Director's Stock Option Plan (collectively the "Incentive Stock Plans"). See "Management--Equity Incentive Plans". Based on the number of shares subject to outstanding options as of June 11, 1998 and currently reserved for issuance under the Incentive Stock Plans, such registration statement would cover approximately 5,600,000 shares. Such registration statement will automatically become effective upon filing. Accordingly, shares registered under such registration statement will, subject to Rule 144 volume limitations applicable to affiliates of the Company, be available for sale in the open market immediately after the 180-day lock-up agreements expire.

Also beginning 180 days after the date of this offering, holders of approximately 8,200,635 Restricted Shares and holders of warrants to purchase 3,038,462 shares of Common Stock will be entitled to certain rights with respect to registration of such shares for sale in the public market. See "Description of Capital Stock--Registration Rights". Registration of such shares under the Securities Act would result in such shares becoming freely tradable without restriction under the Securities Act (except for shares purchased by affiliates) immediately upon the effectiveness of such registration.

The Underwriting Agreement provides that the obligations of the Underwriters are subject to certain conditions precedent and that the Underwriters will purchase all shares of the Common Stock offered hereby if any such shares are purchased.

The Company has been advised by Representatives of the Underwriters that the Underwriters propose to offer the shares of Common Stock directly to the public at the initial offering price set forth on the cover page of this Prospectus and to certain dealers at such price less a concession not in excess of $ per share. The Underwriters may allow, and such dealers may reallow, a concession not in excess of $ per share to certain other dealers. After the initial public offering of the shares, the offering price and other selling terms may be changed by the Representatives of the Underwriters.

The Company has granted to the Underwriters an option, exercisable no later than 30 days after the date of this Prospectus, to purchase up to 450,000 additional shares of Common Stock at the initial public offering price less the underwriting discounts and commissions set forth on the cover page of this Prospectus. To the extent that the Underwriters exercise such option, each of the Underwriters will have a firm commitment to purchase approximately the same percentage of such additional shares as the number set forth next to such Underwriter's name in the above table bears to the total number of shares of Common Stock offered hereby, and the Company will be obligated, pursuant to the option, to sell such shares to the Underwriters to the extent the option is exercised. The Underwriters may exercise such option only to cover over- allotments made in connection with the sale of Common Stock offered hereby. If purchased, the Underwriters will offer such additional shares on the same terms as those on which the 3,000,000 shares are being offered.

The Company has agreed to indemnify the Underwriters against certain liabilities, including liabilities under the Securities Act, and to contribute to payments the Underwriters may be required to make in respect thereof.

The Company and its officers, directors and stockholders have agreed not to offer, sell or otherwise dispose of any shares of Common Stock for a period of 180 days after the date of this Prospectus without the prior written consent of BT Alex. Brown Incorporated. Such consent may be given without any public notice.

Prior to this offering, there has been no public market for the Common Stock of the Company. Consequently, the initial public offering price for the Common Stock will be determined by negotiation between the Company and the Representatives of the Underwriters. Among the factors to be considered in such negotiations will be prevailing market conditions, the results of operations of the Company in recent periods, the market capitalizations and stages of development of other companies that the Company and the Representatives of the Underwriters believe to be comparable to the Company, estimates of the business potential of the Company and its industry in general and the present state of the Company's development and other factors deemed relevant.

The Company has been advised by the Representatives that during and after this offering, the Underwriters may purchase and sell Common Stock in the open market. These transactions may include over-allotment and stabilizing transactions and purchases to cover syndicate short positions created in connection with this offering. Stabilizing transactions consist of certain bids or purchases for the purpose of preventing or retarding a decline in the market price of the Common Stock; and syndicate short positions involve the sale by the Underwriters of a greater number of shares of Common Stock than they are required to purchase from the Company in this offering. The Underwriters also may impose penalty bids, whereby selling concessions allowed to the syndicate members or other broker-dealers in respect of the Common Stock sold in this offering for their account may be reclaimed by the syndicate if such securities are repurchased by the syndicate in stabilizing or short-covering transactions. These activities may stabilize, maintain or otherwise affect the market price of the Common Stock, which may be higher than the price that might otherwise prevail in the open market. These transactions may be effected on the Nasdaq National Market or otherwise and these activities, if commenced, may be discontinued at any time.

The Representatives of the Underwriters have advised the Company that the Underwriters do not intend to confirm orders to any account over which they exercise discretionary authority.

(INFORMATION PERTAINING TO JUNE 30, 1998 AND THE SIX MONTH PERIODS ENDED

JUNE 30, 1997 AND 1998 IS UNAUDITED)

1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Description of Business

Terayon Communication Systems (the Company) was incorporated under the laws of the state of California on January 20, 1993 for the purpose of developing, producing, and marketing broadband access system products. In October 1997, the Company changed its legal name from Terayon Corporation. In July 1998, the Company reincorporated in the State of Delaware. Through December 31, 1996, the Company was active in product development, the acquisition of equipment and facilities, and raising capital; accordingly, the Company was in the development stage. The Company emerged from the development stage during 1997.

Unaudited Interim Financial Information

The accompanying consolidated financial statements at June 30, 1998 and for the six months ended June 30, 1997 and 1998 are unaudited but include all adjustments (consisting of normal recurring accruals) which, in the opinion of management, are necessary for a fair statement of the financial position and the operating results and cash flows for the interim date and periods presented. Results for the interim period ended June 30, 1998 are not necessarily indicative of results for the entire fiscal year or future periods.

Basis of Consolidation

The consolidated financial statements include the accounts of the Company and its majority owned subsidiaries, Terayon Communication Systems Europe and Terayon do Brasil. The minority interests in net losses of Terayon Communication Systems Europe and Terayon do Brasil were not significant for all periods presented. All material intercompany balances and transactions have been eliminated.

Use of Estimates

The preparation of the consolidated financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

Reclassifications

Certain prior year balances have been restated to conform with current year presentation.

Advertising Expenses

The Company accounts for advertising costs as expense in the period in which they are incurred. Advertising expense for the years ended December 31, 1995, 1996 and 1997 and for the six months ended June 30, 1997 and 1998 was not significant.

Cash Equivalents and Short-Term Investments

The Company invests its excess cash in money market accounts and debt instruments and considers all highly liquid debt instruments purchased with an original maturity of three months or less to be cash equivalents. Investments with an original maturity at the time of purchase of over three months but less

than a year are classified as short-term investments. At December 31, 1996 and 1997, approximately 90% and 45%, respectively, of the Company's total cash and short-term investment balance was placed on deposit with an affiliate of a convertible preferred stockholder (none at June 30, 1998). Management determines the appropriate classification of debt and equity securities at the time of purchase and reevaluates such designation at the end of each period.

At December 31, 1996 and 1997, all of the Company's investments in debt securities were classified as available-for-sale and were obligations issued by U.S. government agencies, maturing within one year. The amortized cost, which approximated fair value, of debt instruments classified as cash equivalents and short-term investments was approximately $6,436,000 and $4,508,000, respectively, at December 31, 1996 and approximately $99,000 and $418,000, respectively, at December 31, 1997 (none at June 30, 1998). The amount of unrealized gains or losses was not significant at December 31, 1996 or 1997. The estimated fair values of cash equivalents and short-term investments are based on quoted market prices. The amount of realized gains or losses for the years ended December 31, 1995, 1996, and 1997, and for the six months ended June 30, 1997 and 1998 were not significant.

Concentrations of Credit Risk, Customer, Supplier, and Product

The Company operates in one business segment, the development and sale of cable modem access products, which it sells primarily to customers within the cable and communications industries, including related parties (see Note 12). The Company performs ongoing credit evaluations of its customers and generally requires no collateral. A relatively small number of customers and resellers account for a significant percentage of the Company's revenues. The Company expects that the sale of its products to a limited number of customers and resellers may continue to account for a high percentage of revenues for the foreseeable future.

Currently, the Company relies on single source suppliers of materials and labor for the significant majority of its product inventory but is actively pursuing additional supplier alternatives. As a result, should the Company's current suppliers not produce and deliver inventory for the Company to sell on a timely basis, operating results may be adversely impacted.

Substantially all of the Company's revenues have been attributable to sales of the TeraLink and the TeraPro. These products are expected to account for a significant part of the Company's revenues for the foreseeable future. As a result, a decline in demand for or failure to achieve broad market acceptance of the TeraLink or the TeraPro would adversely affect operating results.

In addition, market acceptance of the Company's products may be affected by the emergence and evolution of industry standards. While the Company expects its products to become compliant with industry standards, its inability to do so may adversely affect operating results.

The Company invests its excess cash in debt instruments of the U.S. Treasury, governmental agencies, and corporations with strong credit ratings. The Company has established guidelines relative to diversification and maturities that attempt to maintain safety and liquidity. The Company has not experienced any significant losses on its cash equivalents or short-term investments.

Other Receivable

At June 30, 1998, the Company had a receivable of $242,000 relating to inventory components the Company was required to purchase from its previous contract manufacturer that were subsequently sold to its current contract manufacturer. Some of the components purchased from the previous subcontract manufacturer were obsolete or sold to the new subcontract manufacturer at a loss. The Company expensed approximately $1,300,000 for the obsolete and sold inventory in the six months ended June 30, 1998.

Property and Equipment

Property and equipment are carried at cost less accumulated depreciation and amortization. Property and equipment are depreciated for financial reporting purposes using the straight-line method over the estimated useful lives of three to five years. Leasehold improvements are amortized using the straight- line method over the shorter of the useful lives of the assets or the terms of the leases.

Revenue Recognition

The Company has also performed some research and product development work under best efforts technology development agreements. Due to technological risk factors, the costs of these agreements have been expensed as incurred and are included in cost of goods sold for the year ended December 31, 1995. Revenues are recognized when applicable customer milestones have been met,

including deliverables and, in any case, not in excess of the amount that would be recognized using the percentage-of-completion method. The Company met deliverables under an agreement in the fourth quarter of the year ended December 31, 1997 and recognized the related revenue (see Note 3).

Warranty Reserves

Due to the recent introduction of the Company's products, the Company has limited experience with warranty commitments that may arise with the current generation of its products. The Company's products generally carry a one-year warranty that includes factory and on-site repair services as needed for replacement of parts. Estimated expenses for warranty obligations are accrued as revenue is recognized. Reserve estimates are adjusted periodically to reflect actual experience.

Stock-Based Compensation

As described in Note 8, the Company has elected to account for its employee stock plans in accordance with Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to Employees" (APB Opinion No.25), and to adopt the disclosure-only provisions as required under Statement of Financial Accounting Standards No. 123, "Accounting for Stock-Based Compensation" (FAS 123).

Net Loss Per Share and Unaudited Pro Forma Stockholders' Equity (Net Capital Deficiency)

Historical basic and diluted net loss per share are computed using the weighted average number of common shares outstanding. Options, warrants, restricted stock and preferred stock were not included in the computation of diluted net loss per share because the effect would be antidilutive.

Pro forma net loss per share has been computed as described above and also gives effect, even if antidilutive, to common equivalent shares from preferred stock that will automatically convert upon the closing of the Company's initial public offering (using the as-if-converted method). If the offering contemplated by this Prospectus is consummated, all of the convertible preferred stock and redeemable convertible preferred stock outstanding as of the closing date will automatically be converted into an aggregate of approximately 8,360,635 shares of common stock based on the shares of convertible preferred stock outstanding at June 30, 1998. Unaudited pro forma shareholders' equity (net capital deficiency) at June 30, 1998, as adjusted for the conversion of preferred stock and redeemable preferred stock, is disclosed on the balance sheet.

Impact of Recently Issued Accounting Standards

In June 1997, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards No. 130, "Reporting Comprehensive Income" (FAS 130). FAS 130 requires that all items required to be recognized under accounting standards as components of comprehensive income be reported in a financial statement that is displayed with the same prominence as other financial statements. FAS 130 is effective for fiscal years beginning after December 15, 1997 and will be adopted by the Company for the year ended December 31, 1998. The Company's total comprehensive loss was the same as its net loss for the six months ended June 30, 1998.

In addition, during June 1997, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards No. 131, "Disclosures About Segments of an Enterprise and Related Information" (FAS 131). FAS 131 replaces FAS 14, "Financial Reporting for Segments of a Business Enterprise" and changes the way public companies report segment information.

3. DEFERRED REVENUE

On January 4, 1995, the Company entered into a Development and Production Agreement with a telecommunications systems manufacturer (the Manufacturer), whereby the Company agreed to develop an enabling technology for use with certain manufacturer technology (the Product). Pursuant to the agreement, the Manufacturer is obligated to purchase certain minimum quantities of the Product, and the Company has agreed to provide the Product to the Manufacturer on favorable pricing terms for a period of four years following completion of the Product. In addition, the Company has agreed that for the first three months following the completion of the Product, the Company will not sell the Product to any third party for use in the carrying of voice-over coaxial cables.

In accordance with the agreement, the Company will receive funding from the Manufacturer totaling $1,000,000. These payments were originally received upon the completion of certain milestones set forth in the agreement. In March 1998, the agreement was amended, and the Company is to receive the remaining payments (in addition to normal Product billings) over a certain number of future unit shipments to the Manufacturer. As of December 31, 1997, approximately $480,000 of cash advances had been received under the agreement. In the fourth quarter of the year ended December 31, 1997, the Company delivered the Product under the agreement and recognized the $480,000 as revenue. During the six months ended June 30, 1998, the Company recognized approximately $163,000 in revenue under this agreement.

4. COMMITMENTS

The Company leases its facility and certain equipment under operating leases. The operating lease for the Company's facility expires in 2002. Rental expense was approximately $114,000, $542,000, and $850,000 for the years ended December 31, 1995, 1996, and 1997, respectively, and approximately $351,000 and $361,000 for the six months ended June 30, 1997 and June 30, 1998, respectively. The Company signed a promissory note of approximately $59,000 in connection with the initial security deposit for the facility. The note did not bear interest and was paid in April 1997.

In March 1996, the Company subleased its former facilities to a third party through December 1997. Sublease rental income was approximately $106,000 and $122,000 for the years ended December 31, 1996 and 1997, respectively and approximately $73,000 for the six months ended June 30, 1997. In October 1997, the master lease and underlying sublease for these facilities were terminated concurrently.

The Company leases certain equipment under noncancelable lease agreements that are accounted for as capital leases. Equipment under capital lease arrangements and included in property and equipment aggregated approximately $452,000 at December 31, 1996 and 1997 and June 30, 1998. Related accumulated amortization was approximately $211,000, $337,000 and $365,000 at December 31, 1996 and 1997, and June 30, 1998, respectively. Amortization expense related to assets under capital leases is included in depreciation expense. In addition, the capital leases are secured by the related equipment, and the Company is required to maintain liability and property damage insurance.

Unconditional Purchase Obligations

The Company has unconditional purchase obligations to a few of its suppliers that support the Company's ability to manufacture its products. The obligations require the Company to purchase minimum quantities of the suppliers' products at a specified price. At June 30, 1998, the Company had approximately $16,340,000 of unconditional purchase obligations ($784,000 at December 31, 1997 and none at December 31, 1996).

5. DEBT OBLIGATIONS

In April 1997, the Company amended an existing credit agreement with a bank to provide for a revolving line of credit up to $10,000,000 and four term loans totaling $4,250,000. Borrowings under the revolving line of credit are limited to the lesser of a) 80% of accounts receivable less than ninety days from the invoice date or b) $10,000,000. Borrowings under the revolving line of credit bear interest at the bank's prime rate plus 0.50% per annum (8.75% at December 31, 1996 and 9.0% at December 31, 1997 and June 30, 1998). There were no borrowings under the revolving line of credit at December 31, 1996 and 1997 and June 30, 1998.

Each term loan is subject to an interest rate calculated at the bank's prime rate plus 1.50% per annum (9.75% at December 31, 1996 and 10% at December 31, 1997 and June 30, 1998). The first term loan is payable in thirty monthly payments consisting of six interest payments and twenty-four equal principal and interest payments through May 1998. Borrowings under the first term loan of approximately $303,000 and $85,000 were outstanding at December 31, 1996 and 1997. There were no borrowings under the first term loan at June 30, 1998.

The second term loan is payable in forty monthly payments of four interest payments and thirty-six equal principal and interest payments through October 1999. Borrowings under the second term loan of approximately $944,000, $611,000, and $444,000 were outstanding at December 31, 1996 and 1997 and June 30, 1998, respectively.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)

(INFORMATION PERTAINING TO JUNE 30, 1998 AND THE SIX MONTH PERIODS ENDED

JUNE 30, 1997 AND 1998 IS UNAUDITED)

The third term loan is payable according to two separate payment schedules. The first payment schedule includes thirty-six equal principal and interest payments through November 1999. At December 31, 1996 and 1997 and June 30, 1998, borrowings under the first payment schedule were approximately $820,000, $539,000 and $398,000, respectively. The second payment schedule consists of thirty-one payments of one interest payment and thirty equal principal and interest payments through December 1999. At December 31, 1997 and June 30, 1998, borrowings under the second payment schedule were approximately $119,000 and $87,000, respectively (none at December 31, 1996).

The fourth term loan is payable in forty-one monthly payments of five interest payments and thirty-six equal principal and interest payments through November 2000. Borrowings under the fourth term loan of approximately $1,458,000 and $1,208,000 were outstanding at December 31, 1997 and June 30, 1998, respectively (none at December 31, 1996).

Outstanding borrowings under the credit agreement are secured by all of the Company's assets. The credit agreement contains affirmative and negative covenants and will, among other things, require the Company to maintain minimum levels of investable funds and liquid assets. The credit agreement also limits the Company's ability to incur additional debt, to pay cash dividends, or to purchase or sell certain assets. Finally, the agreement restricts the Company to a maximum liability to tangible net worth ratio and prohibits certain acquisitions, mergers, consolidations, or similar transactions. At December 31, 1997 and June 30, 1998, the Company was out of compliance with certain covenants contained within the credit agreement and therefore has classified all outstanding borrowings as short-term at those dates.

The Company incurred interest expense related to the term loans of approximately $18,000, $88,000, and $205,000 for the years ended December 31, 1995, 1996, and 1997, respectively and $95,000 and $128,000 for the six months ended June 30, 1997 and 1998, respectively.

6. CONTINGENCIES

During 1997, the Company placed a noncancelable purchase order (subject to specific delivery date requirements) with a subcontract manufacturer. As delivery of the initial shipments was delayed by the manufacturer, the Company subsequently canceled the purchase order without the consent of the subcontract manufacturer. The Company has received notification from the subcontract manufacturer that the Company is obligated to make payment for materials and services rendered under the terms of the purchase order. While management believes that amounts recorded on its financial statements are adequate to cover all related risks, the subcontract manufacturer has not agreed to a settlement with the Company. Although the ultimate outcome of this matter cannot be determined at this time, management does not believe that the outcome will have a material adverse effect on the Company's financial position, results of operations, and cash flows. However, based on future developments, the Company's estimate of the outcome of these matters could change in the near term.

The Company has also received a letter from an individual claiming that the Company's technology infringes a patent held by such individual. The Company has reviewed the allegations made by such individual, and management does not believe that the outcome will have a material adverse effect on the Company's financial position, results of operations, or cash flows.

In the normal course of business, the Company from time to time receives inquiries with regard to various legal proceedings. In the opinion of management, any liability resulting from these inquiries has

been accrued and will not have a material adverse effect on the Company's financial position or results of operations.

7. REDEEMABLE CONVERTIBLE PREFERRED STOCK

In December 1997, the Company entered into a Series E redeemable convertible preferred stock agreement ("the Agreement"). The Agreement calls for the establishment of a $5,000,000 escrow account to fund the issuance of up to 333,334 shares of Series E redeemable convertible preferred stock ("the Stock") for cash at $15.00 per share. The escrow account will release cash to the Company as the Company reaches certain technological and customer base milestones as defined under the Agreement. Upon the first closing, the Company is also to issue a warrant to purchase up to an additional 33,334 shares of the Stock at $15.00 per share. In the event the final closing of the Agreement does not occur prior to the earlier of the (a) completion of the Company's initial public offering of shares of its Common Stock and (b) December 31, 1998, then any amount remaining in the escrow account will be returned to the Series E stockholder.

In February 1998, the Company reached a milestone under the Series E redeemable convertible preferred stock agreement and issued 100,000 shares of Series E redeemable convertible preferred stock, resulting in cash proceeds of approximately $1,500,000 to the Company. In conjunction with this issuance, the Company issued a warrant to the Series E stockholder to purchase 33,334 shares of the Company's redeemable convertible preferred stock at $15.00 per share.

In June 1998, the Company and the Series E stockholder amended the Series E redeemable convertible preferred stock agreement (the "Amendment"). The Amendment calls for the cancellation of all Series E redeemable convertible preferred stock outstanding with the $1,500,000 of proceeds from the cancellation being applied toward the issuance of 115,385 shares of Series D redeemable convertible preferred stock. In addition, all future milestones under the Series E redeemable convertible preferred stock agreement were canceled under the Amendment and 269,231 additional shares of Series D redeemable convertible preferred stock were issued resulting in additional proceeds of approximately $3,500,000. The Amendment also cancelled the warrant for the purchase of 33,334 Series E redeemable convertible preferred stock at $15.00 per share and issued a warrant for the purchase of 38,462 shares of Series D redeemable convertible preferred stock with an exercise price of $13.00 per share. The warrant is immediately exercisable and expires on the earlier of the effective date of the Company's initial public offering or June 11, 2003. The Company has recorded an expense of $19,000 to reflect the value of this warrant for the six months ended June 30, 1998.

The Series D redeemable convertible preferred stockholder also has the option to sell to the Company some or all of the 384,616 redeemable shares held by the Series D redeemable convertible preferred stockholder (the "Put Right") any time after July 1, 1998. The price paid by the Company to the Series D redeemable convertible preferred stockholder for any shares purchased pursuant to the Put Right is $13.00 per share. In the event of the exercise of the Put Right, the Company will apply the total amount of the Put Right toward the purchase of the Company's products. Any of the redeemable shares not sold back to the Company by the Series D redeemable convertible preferred stockholder will retain their Put Right until the Put Termination Date which is defined under the Agreement as the earlier of (a) February 20, 1999 and (b) the completion of the Company's initial public offering of shares of its Common Stock. In addition, in the event that prior to the Put Termination Date either
(a) the completion of the Company's initial public offering of shares of its Common Stock has not occurred or (b) an acquisition of at least ninety percent of all of the Company's capital stock has not occurred, then the

Series D redeemable convertible preferred stockholder has the right to receive a cash payment from the Company in an amount equal to ten percent of the aggregate purchase price of the number of redeemable shares held by the Series D redeemable convertible preferred stockholder as of the Put Termination Date.

In June 1998, the Company issued 192,308 shares of Series F redeemable convertible preferred stock resulting in proceeds of approximately $2,500,000 to the Company. Series F redeemable convertible preferred stock also contains an option that allows the Series F stockholder to sell some or all of the redeemable shares back to the Company at a price of $13.00 per share any time after June 1, 1999 to be used toward the purchase of the Company's products. Any of the redeemable shares not sold back to the Company by the Series F stockholder will retain the option until the completion of the Company's initial public offering of shares of its common stock.

8. STOCKHOLDERS' EQUITY (NET CAPITAL DEFICIENCY)

Convertible Preferred Stock

In April 1998, the Company's Board of Directors approved an increase in the authorized number of shares of convertible preferred stock to 10,399,097 shares.

In April 1998, the Company issued 384,615 shares of Series F convertible preferred stock and a warrant to purchase 3,000,000 shares of the Company's common stock at an exercise price of $6.50 per share, resulting in cash proceeds of approximately $5,000,000 to the Company. The warrant is exercisable at any time on or after April 6, 2003 and prior to December 31, 2003. The exercisability of the warrant can be accelerated based upon purchases of the Company's cable modem product by the Series F convertible preferred stockholder during the years ended December 31, 1998, 1999, and 2000 as defined within the warrant.

In April 1998, a $2,000,000 advance received from a Series D preferred stockholder in 1997 was converted into 153,846 shares of Series D convertible preferred stock (see Note 12).

In June 1998, the Company also issued 114,089 shares of Series D convertible preferred stock resulting in additional net proceeds of approximately $1,454,000 to the Company.

Convertible preferred stockholders and redeemable convertible preferred stockholders have the same voting rights as common stockholders. In addition, the Series A, B, B-1, C, D, E and F stockholders will vote as a single class. In the event of any voluntary or involuntary liquidation of the Company, Series A, B, B-1, C, D, E and F stockholders are entitled to a per share liquidation preference of $0.9545, $8.92, up to $17.84, $12.50, up to $19.50, up to $22.50, and up to $19.50, respectively, plus accrued dividends, if any.

Each share of preferred stock and redeemable preferred stock is convertible at the option of the holder into one share of common stock, subject to adjustments for future dilution since the date of issuance. Each share of Series A, B, and B-1 preferred stock automatically converts into common stock at the then applicable conversion rate upon the earlier of (a) the public offering of the Company's common stock with aggregate proceeds in excess of $10,000,000 or (b) the date on which the Company obtains the consent of at least two-thirds of the shares of Series A, B, and B-1 stockholders separately by class. Each share of Series C preferred stock automatically converts at the earlier of (a) the public offering of the Company's common stock at a per share price of $12.50 (b) the end of any twenty-day period after a public offering of the Company's common stock during which the closing sales price per share was at least $12.50, or (c) the date on which the Company obtains the consent of at least two-thirds of the shares of Series C stockholders, as applicable. Each share of Series D preferred and redeemable preferred stock, Series E preferred stock, and Series F preferred and redeemable preferred stock automatically converts at the earlier of (a) the public offering of the Company's common stock at a per share price of $13.00 or (b) the date on which the Company obtains the consent of at least two-thirds of the shares of Series D, E and Series F stockholders, as applicable. The Company has fully reserved shares of common stock for issuance upon the conversion of the convertible preferred stock and redeemable convertible preferred stock.

Stock-Based Compensation

In March 1995 and February 1997, the Board of Directors approved a stock option plan and an equity incentive plan, respectively, that authorized the grant of options to purchase shares of the Company's common stock. At December 31, 1997, the total authorized number of shares under the 1995 and 1997 plans was 2,114,747 and 1,050,000, respectively. The plans are administered by the Board of Directors and provide for incentive stock options or nonqualified stock options to be issued to employees, directors, and consultants of the Company. Prices for incentive stock options may not be less than the fair value of the common stock at the date of grant. Prices for nonqualified stock options may not be less than 85% of the fair value of the common stock at the date of grant. Options are immediately exercisable and vest over a period not to exceed five years from the date of grant. Any unvested stock issued is subject to repurchase by the Company at the original issuance price upon termination of the option holder's employment. Unexercised options expire ten years after the date of grant.

In March and July 1997, the Board of Directors authorized grants of common stock options outside the Company's stock option plans. The options are for 70,000 shares of common stock and generally vest over a three-year period in six equal installments occurring every six months. In May and June 1998, the Board of Directors authorized additional grants of 70,000 shares of common stock outside the Company's stock option plans.

In June 1998, the Company's Board of Directors authorized (i) the adoption of the amended 1997 Equity Incentive Plan, pursuant to which 2,250,000 additional shares (plus a number of shares equal to the difference between the number of shares remaining available for grant and the number of shares equal to 5% of the Company's outstanding common stock at each year end) of the Company's common stock have been reserved for future issuance to selected employees, directors and consultants, (ii) the adoption of the 1998 Non-Employee Directors' Stock Option Plan, pursuant to which 200,000 shares of the Company's common stock have been reserved for future issuance to non-employee directors of the Company, and (iii) the adoption of the 1998 Employee Stock Purchase Plan, pursuant to which 700,000 shares of the Company's common stock have been reserved for future issuance to eligible employees.

During the year ended December 31, 1997 and the six months ended June 30, 1998, the Company recorded aggregate deferred compensation of approximately $228,000 and $1,849,000, respectively, representing the difference between the grant price and the deemed fair value of the Company's common stock options granted during these periods. The amortization of deferred compensation is being charged to operations and is being amortized over the vesting period of the options, which is typically five years. For the year ended December 31, 1997 and the six months ended June 30, 1998, the amortized expense was approximately $12,000 and $106,000, respectively.

At December 31, 1997 and June 30, 1998, 103,050 and 127,152 shares, respectively, of common stock outstanding were subject to repurchase by the Company.

The Company has elected to follow APB Opinion No. 25 and related interpretations in accounting for its employee stock options because, as discussed below, the alternative fair value accounting provided for under FAS 123 requires the use of option valuation models that were not developed for use in valuing employee stock options. Under APB Opinion No. 25, when the exercise price of the Company's employee stock options equals the market price of the underlying stock on the date of grant, no compensation expense is recognized.

Pro forma information regarding net loss is required under FAS 123 and is calculated as if the Company had accounted for its employee stock options granted during the years ended December 31, 1995, 1996 and 1997 under the fair value method of FAS 123. The fair value for these options was estimated at the date of grant using the minimum value method with the following weighted average assumptions: risk-free interest rates of 5.34%, 6.22%, and 5.75% for 1995, 1996, and 1997, respectively; no dividend yield or volatility factors of the expected market price of the Company's common stock; and a weighted average expected life of the option of five years.

As discussed above, the option valuation models used under FAS 123 were developed for use in estimating the fair value of traded options that have no vesting restrictions and are fully transferable. In addition, option valuation models require the input of highly subjective assumptions, including the expected life of the option. Because the Company's employee stock options have characteristics significantly different from those of traded options and because changes in the subjective input assumptions can materially affect the fair value estimate, in management's opinion, the existing models do not necessarily provide a reliable single measure of the fair value of its employee stock options.

For purposes of pro forma disclosures, the estimated fair value of the options is amortized to expense over the options' vesting period. Had compensation cost for the Company's stock-based compensation plans been determined based on the fair value at the grant dates for awards under those plans consistent with the method of FAS 123, the Company's net loss and loss per share would have been increased to the pro forma amounts indicated below (in thousands, except per share data):

The pro forma impact of options on the net loss for the years ended December 31, 1995, 1996, and 1997 is not representative of the effects on net income
(loss) for future years, as future years will include the effects of options vesting as well as the impact of multiple years of stock option grants. The full effect of FAS 123 will not be fully reflected until 1999.

The options' weighted average grant date fair value, which is the value assigned to the options under FAS 123, was $0.02, $0.11, and $0.41 for options granted during 1995, 1996, and 1997, respectively.

Stockholders' Notes Receivable

In February 1993, the Company issued common stock to a founder in return for a full recourse note receivable for $12,500. The note bears an interest rate of 7.04% per annum and is due in February 1998.

During June and December 1995, two officers of the Company were provided cash advances totaling $81,133 for the purpose of purchasing the Company's Series A preferred stock. The underlying full recourse notes were paid in August 1996 and June 1998.

In September 1997, the Company issued common stock to an employee in return for a full recourse note receivable for $13,000. The note bears an interest rate of 5.81% per annum and is due in September 1998. Pursuant to the stock purchase agreement, the employee has the option to sell some or all of his shares to the Company on or after September 22, 1998 at a purchase price of $13.00 per share (the "Put Price"). Such option expires upon the earlier of September 22, 2003 and b) the completion of the Corporation's initial public offering of shares of its Common Stock. The Company has accrued the difference between the note receivable's per share price and the Put Price over the option's vesting period and included the cumulative difference in other accrued liabilities as of March 31, 1998. The note receivable was paid in full in January 1998.

In January 1998, the Company issued common stock to an employee in exchange for a full recourse note receivable for $9,375. The note bears interest at 5.7% and is payable in three equal annual payments commencing in January 1999.

9. INCOME TAXES

Due to operating losses and the inability to recognize the benefits therefrom, there is no provision for income taxes for the fiscal years ended December 31, 1995, 1996, and 1997.

Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Significant components of the Company's deferred tax assets as of December 31, 1996 and 1997 are as follows (in thousands):

Realization of deferred tax assets is dependent on future earnings, if any, the timing and the amount of which are uncertain. Accordingly, a valuation allowance, in an amount equal to the net deferred tax asset as of December 31, 1996 and 1997, has been established to reflect these uncertainties. The change in the valuation allowance was a net increase of approximately $1,533,000, $4,444,000, and $10,329,000 for the years ended December 31, 1995, 1996, and 1997, respectively.

As of December 31, 1997, the Company had federal and California net operating loss carryforwards of approximately $31,000,000 and $15,000,000, respectively. The Company also had federal and California research and development tax credit carryforwards of approximately $1,700,000 and $1,200,000, respectively. The net operating loss and credit carryforwards will expire at various dates beginning in the years 1999 through 2012, if not utilized.

Utilization of net operating loss and tax credit carryforwards may be subject to a substantial annual limitation due to the ownership change limitations provided by the Internal Revenue Code of 1986, as amended, and similar state provisions. The annual limitation may result in the expiration of net operating loss and tax credit carryforwards before full utilization.

The Company may make discretionary contributions based on profitability as determined by the Board of Directors. No amount was contributed by the Company to the plan during the years ended December 31, 1995, 1996, and 1997 or for the six months ended June 30, 1997 and 1998.

12. RELATED PARTY TRANSACTIONS

During the year ended December 31, 1997, the Company recognized revenue of approximately $617,000 in connection with product shipments made to a Series D preferred stockholder. In addition, during the six months ended June 30, 1998, the Company recognized revenue of approximately $1,312,000 and $3,785,000 in connection with product shipments made to a Series D preferred stockholder, and a Series F redeemable preferred and preferred stockholder, respectively. Accounts receivable from the related parties totaled approximately $362,000 and $2,236,000 at December 31, 1997 and June 30, 1998, respectively.

In September 1997, the Company received $2,000,000 from a Series D preferred stockholder in connection with a stock option agreement. As of December 31, 1997, the Company has recorded the amount received as an advance from the related party. The stock option agreement allows for the purchase of 153,846 shares of Series D preferred stock for the $2,000,000, on or before April 30, 1998. In April 1998, the $2,000,000 advance was converted into 153,846 shares of Series D convertible preferred stock.

13. SUBSEQUENT EVENT--DELAWARE REINCORPORATION

In June 1998, the Company's Board of Directors authorized the reincorporation of the Company in Delaware and an increase in the authorized number of shares of common stock from 20,000,000 shares to 35,000,000 shares. In July 1998, the Company's shareholders approved the reincorporation and the increase in authorized number of shares, and the reincorporation was effective as of July 8, 1998. The par value of the preferred and common stock is $.001 per share. Subsequent to the initial public offering, the Company's Certificate of Incorporation will be amended to authorize 5,000,000 shares of preferred stock which the Board of Directors has the authority to fix or alter the designation, powers, preferences and rights of the shares of each such series and qualifications, limitations or restrictions to any unissued series of preferred stock. The Company's reincorporation has been reflected in the June 30, 1998 consolidated financial statements. The change resulted in the transfer of $44,205,000 from convertible preferred stock and $2,415,000 from common stock to additional paid in capital.

ITEM 17. UNDERTAKINGS.

The undersigned Registrant hereby undertakes to provide the Underwriters at the closing specified in the Underwriting Agreement certificates in such denominations and registered in such names as required by the Underwriters to permit prompt delivery to each purchaser.

Insofar as indemnification for liabilities arising under the Securities Act of 1933 (the "Act") may be permitted to directors, officers, and controlling persons of the Registrant pursuant to the provisions described in Item 14 or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer, or controlling person of the Registrant in the successful defense of any action, suit, or proceeding) is asserted by such director, officer, or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

The undersigned Registrant hereby undertakes that: (1) for purposes of determining any liability under the Act, the information omitted from the form of prospectus as filed as part of the registration statement in reliance upon Rule 430A and contained in the form of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Act shall be deemed to be part of the registration statement as of the time it was declared effective,
(2) for the purpose of determining any liability under the Act, each post- effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and this offering of such securities at that time shall be deemed to be the initial bona fide offering thereof, and (3) to remove from registration by means of a post- effective amendment any of the securities being registered which remain unsold at the termination of the offering.

If, upon the occurrence of such event, the assets and funds thus distributed among the holders of the Series A Preferred Stock, Series B Preferred Stock, Series B-1 Preferred Stock, Series C Preferred Stock, Series D Preferred Stock, Series E Preferred Stock and Series F Preferred Stock shall be insufficient to permit the payment to such holders of the full aforesaid preferential amount, then the entire assets and funds of the corporation legally available for distribution shall be distributed ratably among the holders of the Series A Preferred Stock, Series B Preferred Stock, Series B-1 Preferred Stock,

3.


Series C Preferred Stock, Series D Preferred Stock, Series E Preferred Stock and Series F Preferred Stock in proportion to the preferential amount each such holder is otherwise entitled to receive.

(a) RIGHT TO CONVERT. Each share of Series A Preferred Stock, Series B Preferred Stock, Series B-1 Preferred Stock, Series C Preferred Stock, Series D Preferred Stock, Series E Preferred Stock and Series F Preferred Stock shall be convertible, at the option of the

4.


holder thereof, at the office of the corporation or any transfer agent for such stock. The number of shares of Common Stock to which a holder of Series A Preferred Stock, Series B Preferred Stock, Series B-1 Preferred Stock, Series C Preferred Stock, Series D Preferred Stock, Series E Preferred Stock or Series F Preferred Stock shall be entitled upon conversion shall be the product obtained by multiplying the applicable "Conversion Rate," determined as hereinafter provided, then in effect by the number of shares of Series A Preferred Stock, Series B Preferred Stock, Series B-1 Preferred Stock, Series C Preferred Stock, Series D Preferred Stock, Series E Preferred Stock or Series F Preferred Stock being converted by such holder.

The conversion rate in effect at any time for conversion of the shares of Series A Preferred (the "Series A Conversion Rate") shall be the quotient obtained by dividing $0.9545 by the "Series A Conversion Price," determined as hereinafter provided, in effect on the date the certificate is surrendered for conversion. The conversion rate in effect at any time for conversion of the shares of Series B Preferred (the "Series B Conversion Rate") shall be the quotient obtained by dividing $8.92 by the "Series B Conversion Price," determined as hereinafter provided, in effect on the date the certificate is surrendered for conversion.

The conversion rate in effect at any time for conversion of the shares of Series C Preferred (the "Series C Conversion Rate") shall be the quotient obtained by dividing $12.50 by the "Series C Conversion Price" determined as hereinafter provided, in effect on the date the certificate is surrendered for conversion. The conversion rate in effect at any time for conversion of the shares of Series D Preferred (the "Series D Conversion Rate") shall be the quotient obtained by dividing $13.00 by the "Series D Conversion Price" determined as hereinafter provided, in effect on the date the certificate is surrendered for conversion.

The conversion rate in effect at any time for conversion of the shares of Series F Preferred (the "Series F Conversion Rate") shall be the quotient obtained by dividing $13.00 by the "Series F Conversion Price" determined as hereinafter provided, in effect on the date the certificate is surrendered for conversion.

5.


Rate upon the date specified by vote or written consent of holders of at least two-thirds of the shares of the Series A Preferred Stock; each share of Series B Preferred Stock shall automatically be converted into shares of Common Stock at the then-effective Series B Conversion rate upon the date specified by vote or written consent of holders of at least two-thirds of the shares of the Series B Preferred Stock; each share of Series B-1 Preferred Stock shall automatically be converted into shares of Common Stock at the then-effective Series B-1 Conversion Rate upon the date specified by vote or written consent of holders of at least two-thirds of the shares of the Series B-1 Preferred Stock; each share of Series C Preferred Stock shall automatically be converted into shares of Common Stock at the then-effective Series C Conversion Rate upon the date specified by vote or written consent of holders of at least two-thirds of the shares of the Series C Preferred Stock; each share of Series D Preferred Stock shall automatically be converted into shares of Common Stock at the then-effective Series D Conversion Rate upon the date specified by vote or written consent of holders of at least two-thirds of the shares of the Series D Preferred Stock; each share of Series E Preferred Stock shall automatically be converted into shares of Common Stock at the then-effective Series E Conversion Price upon the date specified by vote or written consent of holders of at least two-thirds of the shares of Series E Preferred Stock and each share of Series F Preferred Stock shall automatically be converted into shares of Common Stock at the then-effective Series F Conversion Price upon the date specified by vote or written consent of holders of at least two-thirds of the shares of Series F Preferred Stock.

Each share of Series C Preferred Stock shall automatically be converted into shares of Common Stock at the then-effective Series C Conversion Rate immediately upon the earlier of (i) the closing of the sale of the corporation's Common Stock in a Qualified Public Offering at a price per share equal to or exceeding $12.50 (as adjusted for any stock dividends, combinations or splits with respect to such shares) or (ii) the end of any twenty (20) day period after a Qualified Public Offering during which the closing sales price per share (or closing bid, if no sales were reported) of the Common Stock of the corporation as quoted on any established stock exchange or a national market system, including, without limitation, the Nasdaq National Market or the Nasdaq SmallCap, was at least $12.50 (as adjusted for any stock dividends, combinations or splits with respect to such shares) for each day during such period. Each share of Series D Preferred Stock, Series E Preferred Stock and Series F Preferred Stock shall automatically be converted into shares of Common Stock at the then-effective Series D Conversion Rate , Series E Conversion Rate or Series F Conversion Rate, as the case may be, immediately upon the closing of the sale of the corporation's Common Stock in a Qualified Public Offering at a price per share equal to or exceeding $13.00 (as adjusted for any stock dividends, combinations or splits with respect to such shares).

(c) MECHANICS OF CONVERSION. Before any holder of Series A Preferred Stock, Series B Preferred Stock, Series B-1 Preferred Stock, Series C Preferred Stock, Series D Preferred Stock, Series E Preferred Stock or Series F Preferred Stock shall be entitled to convert the same into shares of Common Stock, such holder shall surrender the certificate or certificates therefor, duly

6.


endorsed, at the office of the corporation or any transfer agent for such stock, and shall give written notice to the corporation at such office that such holder elects to convert the same and shall state therein the name or names in which such holder wishes the certificate or certificates for shares of Common Stock to be issued. The corporation shall, as soon as practicable thereafter, issue and deliver at such office to such holder of Series A Preferred Stock, Series B Preferred Stock, Series B-1 Preferred Stock, Series C Preferred Stock, Series D Preferred Stock, Series E Preferred Stock or Series F Preferred Stock a certificate or certificates for the number of shares of Common Stock to which such holder shall be entitled as aforesaid. Such conversion shall be deemed to have been made immediately prior to the close of business on the date of surrender of the shares of Preferred Stock to be converted, and the person or persons entitled to receive the shares of Common Stock issuable upon such conversion shall be treated for all purposes as the record holder or holders of such shares of Common Stock on such date.

(d) ADJUSTMENTS TO CONVERSION PRICES FOR STOCK DIVIDENDS AND FOR COMBINATIONS OR SUBDIVISIONS OF COMMON STOCK. In the event that this corporation shall declare or pay, without consideration, any dividend on the Common Stock payable in Common Stock or in any right to acquire Common Stock for no consideration, or shall effect a subdivision of the outstanding shares of Common Stock into a greater number of shares of Common Stock (by stock split, reclassification or otherwise than by payment of a dividend in Common Stock or in any right to acquire Common Stock), or in the event the outstanding shares of Common Stock shall be combined or consolidated, by reclassification or otherwise, into a lesser number of shares of Common Stock, then the Series A Conversion Price, Series B Conversion Price, Series B-1 Conversion Price, Series C Conversion Price, Series D Conversion Price, Series E Preferred Conversion Price and Series F Conversion Price in effect immediately prior to such event shall, concurrently with the effectiveness of such event, be proportionately decreased or increased, as appropriate. In the event that this corporation shall declare or pay, without consideration, any dividend on the Common Stock payable in any right to acquire Common Stock for no consideration, then the corporation shall be deemed to have made a dividend payable in Common Stock in an amount of shares equal to the maximum number of shares issuable upon exercise of such rights to acquire Common Stock.

(e) ADJUSTMENTS FOR RECLASSIFICATION AND REORGANIZATION. If the Common Stock issuable upon conversion of the Series A Preferred Stock, Series B Preferred Stock, Series B-1 Preferred Stock, Series C Preferred Stock, Series D Preferred Stock, Series E Preferred Stock and Series F Preferred Stock shall be changed into the same or a different number of shares of any other class of classes of stock, whether by capital reorganization, reclassification or otherwise (other than a subdivision or combination of shares provided for in Section 3(d) above or a merger or other reorganization referred to in Section 2(d) above), the Series A Conversion Price, the Series B Conversion Price, Series B-1 Conversion Price, Series C Conversion Price, Series D Conversion Price, Series E Conversion Price and Series F Conversion Price then in effect shall, concurrently with the effectiveness of such reorganization or reclassification, be proportionately adjusted so that the Series A Preferred Stock, Series B Preferred Stock, Series B-1 Preferred Stock, Series C Preferred Stock, Series D Preferred Stock, Series E Preferred Stock and Series F Preferred Stock shall be convertible into, in lieu of the number of shares of Common Stock which the holders would otherwise have been entitled to receive, a number of shares of such other class of classes of stock equivalent to the number of shares of Common Stock that would have been subject to receipt by the holders upon conversion of the Series A Preferred Stock, Series B Preferred Stock, Series B-1

7.


Preferred Stock, Series C Preferred Stock, Series D Preferred Stock, Series E Preferred Stock and Series F Preferred Stock immediately before that change.

8.


Effective Price less than the then effective Conversion Price for the Series D Preferred Stock, then, and in each such case, such Conversion Price shall be reduced, as of the opening of business on the date of such issue or sale, to a price determined by multiplying such Conversion Price by a fraction (i) the numerator of which shall be (A) the number of shares of Common Stock issued or issuable upon conversion of the Series A Preferred Stock, Series B Preferred Stock, Series B-1 Preferred Stock, Series C Preferred Stock, Series D Preferred Stock, Series E Preferred Stock and Series F Preferred Stock outstanding immediately prior to such issue or sale, plus (B) the number of shares of Common Stock which the aggregate consideration received (as defined in subsection (f)(4)) by the corporation for the total number of Additional Shares of Common Stock so issued would purchase at such Conversion Price, and (ii) the denominator of which shall be the number of shares of Common Stock issued or issuable upon conversion of the Series A Preferred Stock, Series B Preferred Stock, Series B-1 Preferred Stock, Series C Preferred Stock, Series D Preferred Stock, Series E Preferred Stock and Series F Preferred Stock outstanding immediately prior to such issue or sale plus the total number of Additional Shares of Common Stock so issued.

If at any time or from time to time the corporation issues or sells, or is deemed by the express provisions of this subsection (f) to have issued or sold, Additional Shares of Common Stock, other than as a dividend or other distribution on any class of stock as provided in Section 3(d) above, and other than a subdivision or combination of shares of Common Stock as provided in Section 3(d) above, for an Effective Price less than the then effective Conversion Price for the Series F Preferred Stock, then, and in each such case, such Conversion Price shall be reduced, as of the opening of business on the date of such issue or sale, to a price determined by multiplying such Conversion Price by a fraction (i) the numerator of which shall be (A) the number of shares of Common Stock issued or issuable upon conversion of the Series A Preferred Stock, Series B Preferred Stock, Series B-1 Preferred Stock, Series C Preferred Stock, Series D Preferred Stock, Series E Preferred Stock and Series F Preferred Stock outstanding immediately prior to such issue or sale, plus (B) the number of shares of Common Stock which the aggregate consideration received (as defined in subsection (f)(4)) by the corporation for the total number of Additional Shares of Common Stock so issued would purchase at such Conversion Price, and (ii) the denominator of which shall be the number of shares of Common Stock issued or issuable upon conversion of the Series A Preferred Stock, Series B Preferred Stock, Series B-1 Preferred Stock, Series C Preferred Stock, Series D Preferred Stock, Series E Preferred Stock and Series F Preferred Stock outstanding immediately prior to such issue or sale plus the total number of Additional Shares of Common Stock so issued. For the purposes of the preceding sentence, the number of shares of Common Stock issued or issuable upon conversion of the Series A Preferred Stock, Series B Preferred Stock, Series B-1 Preferred Stock, Series C Preferred Stock, Series D Preferred Stock, Series E Preferred Stock and Series F Preferred Stock outstanding as of a given date shall be the sum of (A) the number of shares of Common Stock issuable upon conversion of the Series A Preferred Stock, Series B Preferred Stock, Series B-1 Preferred Stock, Series C Preferred Stock, Series D Preferred Stock, Series E Preferred Stock and Series F Preferred Stock actually outstanding, (B) the number of shares of Common Stock that have been issued upon conversion of the Series A Preferred Stock, Series B Preferred Stock, Series B-1 Preferred Stock, Series C Preferred Stock, Series D Preferred Stock, Series E Preferred Stock and Series F Preferred Stock, and (C) the number of shares of Common Stock issuable upon conversion of the Series A Preferred Stock, Series B Preferred Stock, Series B-1 Preferred Stock, Series C Preferred Stock, Series D Preferred Stock, Series E Preferred Stock and Series F Preferred Stock,

10.


which Preferred Stock could be obtained through the exercise or conversion of all other rights, options, warrants and convertible securities on the day immediately preceding the given date.

(5) For the purpose of making any adjustment required under
Section 3(f)(1), (2), or (3) the consideration received by the corporation for any issue or sale of securities shall (A) to the extent it consists of cash, be computed at the net amount of cash received by the corporation after deduction of any underwriting or similar commissions, compensation or concessions paid or allowed by the corporation in connection with such issue or sale but without deduction of any expenses payable by the corporation, (B) to the extent it consists of property other than cash, be computed at the fair value of that property as determined in good faith by the Board of Directors, and (C) if Additional Shares of Common Stock, Convertible Securities (as hereinafter defined) or rights, options or warrants to purchase either Additional Shares of Common Stock or Convertible Securities are issued or sold together with other stock or securities or other assets of the corporation for a consideration which covers both, be computed as the portion of the consideration so received that may be reasonably determined in good faith by the Board of Directors to be allocable to such Additional Shares of Common Stock, Convertible Securities, rights, options or warrants.

(6) For the purpose of any adjustment required under Section
3(f)(1), (2), or (3) if the corporation issues or sells any rights, options or warrants for the purchase of Common Stock or Preferred Stock, or stock or other securities convertible, exercisable or exchangeable into Common Stock or Preferred Stock (such rights, options or warrants for the purchase of Common Stock or Preferred Stock, or stock or other securities convertible, exercisable or exchangeable into Common Stock or Preferred Stock being herein referred to as "Convertible Securities"), and if the Effective Price of such Convertible Securities is less than the Series C Conversion Price, the Series D Conversion Price, the Series E Conversion Price or the Series F Conversion Price, as applicable, in each case, the maximum number of shares of Common Stock issuable upon exercise, exchange and/or conversion thereof shall be deemed to be Additional Shares of Common Stock as of the date of issuance of the Convertible Securities and the corporation shall be deemed to have received as consideration for the issuance of such shares an amount equal to the total amount of the consideration, if any, received by the corporation for the issuance of such Convertible Securities, plus the minimum amount of consideration, if any, payable to the corporation upon the exercise, exchange or conversion of the Convertible Securities; provided that if the minimum amounts of such consideration cannot be ascertained, but are a function of antidilution or similar protective clauses, the corporation shall be deemed to have received the minimum amounts of consideration without reference to such clauses; provided further that if the minimum amount of consideration payable to the corporation upon the exercise, exchange or conversion of Convertible Securities is reduced over time or on the occurrence or non- occurrence of specified events other than by reason of antidilution adjustments, the Effective Price shall be recalculated using the figure to which such minimum amount of consideration is reduced; provided further that if the minimum amount of consideration payable to the corporation upon the exercise, exchange or conversion of such Convertible Securities is subsequently increased, the Effective Price shall be again recalculated using the increased minimum amount of consideration payable to the corporation upon the exercise, exchange or conversion of such Convertible Securities. No further adjustment of the Series C Conversion Price, Series D Conversion Price , Series E Conversion Price or Series F Conversion Price, as applicable, as adjusted upon the issuance of such Convertible Securities, shall be made as a result of the actual issuance of Additional Shares of Common Stock

11.


on the exercise, exchange or conversion of any such Convertible Securities. If any such exercise, exchange or conversion privilege represented by any such Convertible Securities shall expire without having been exercised, exchanged or converted, the Series C Conversion Price, Series D Conversion Price, Series E Conversion Price or Series F Conversion Price, as applicable, as adjusted upon the issuance of such Convertible Securities, shall be readjusted to the Series C Conversion Price, Series D Conversion Price, Series E Conversion Price or Series F Conversion Price, as applicable, that would have been in effect had an adjustment been made on the basis that the only Additional Shares of Common Stock so issued were the Additional Shares of Common Stock, if any, actually issued or sold on the exercise, exchange or conversion of such Convertible Securities, and such Additional Shares of Common Stock, if any, were issued or sold for the consideration actually received by the corporation upon such exercise, exchange or conversion, plus the consideration, if any, actually received by the corporation for the issuance of such Convertible Securities whether or not exercised, exchanged or converted; provided that such readjustment shall not apply to prior conversions of Series C Preferred Stock, Series D Preferred Stock, Series E Preferred Stock or Series F Preferred Stock, as applicable.

(7) "Additional Shares of Common Stock" shall mean all shares of Common Stock issued by the corporation or deemed to be issued pursuant to this Section 3(f), whether or not subsequently reacquired or retired by the corporation other than (1) shares of Common Stock issued upon conversion of the Series A, Series B, Series B-1, Series C Preferred Stock, Series D Preferred Stock, Series E Preferred Stock and Series F Preferred Stock; (2) shares of Common Stock and/or options, warrants or other Common Stock purchase rights and the Common Stock issued pursuant to such options, warrants or other rights issued or to be issued to employees, officers or directors of, or consultants or advisors to the corporation or any subsidiary in connection with the provision of the services to the same pursuant to stock purchase or stock option plans or other arrangements that are approved by the Board; (3) shares of Common Stock issued pursuant to the Company's acquisition of another corporation by merger, purchase of substantially all assets or other reorganization; (4) shares of Common Stock issued in connection with equipment lease financing arrangements, credit agreements or other commercial transactions approved by the Board of Directors; and (5) shares of Common Stock issued pursuant to a corporate strategic partner transaction involving the license of technology, establishment of a joint venture, research and development agreement, product development or marketing agreement, or other similar arrangement.

(8) The "Effective Price" of Additional Shares of Common Stock or Convertible Securities, as applicable, shall mean the quotient determined by dividing the total number of Additional Shares of Common Stock or Convertible Securities, as applicable, issued or sold, or deemed to have been issued or sold by the corporation under this Section 3(f), into the aggregate consideration received, or deemed to have been received by the corporation for such issue under this Section 3(f), for such Additional Shares of Common Stock or Convertible Securities, as applicable.

(g) NO IMPAIRMENT. The corporation will not, by amendment of its certificate of incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed hereunder by the corporation, but will at all times in good faith assist in the carrying out of all the

12.


provisions of this Section 3 and in the taking of all such action as may be necessary or appropriate in order to protect the conversion rights of the holders of the Series A Preferred Stock, Series B Preferred Stock, Series B-1 Preferred Stock, Series C Preferred Stock, Series D Preferred Stock, Series E Preferred Stock and Series F Preferred Stock against impairment.

(h) CERTIFICATES AS TO ADJUSTMENTS. Upon the occurrence of each adjustment or readjustment of any Conversion Price pursuant to this
Section 3, the corporation at its expense shall promptly compute such adjustment or readjustment in accordance with the terms hereof and prepare and furnish to each holder of Series A Preferred Stock, Series B Preferred Stock, Series B-1 Preferred Stock, Series C Preferred Stock, Series D Preferred Stock, Series E Preferred Stock and Series F Preferred Stock a certificate executed by the corporation's chief financial officer setting forth such adjustment or readjustment and showing in detail the facts upon which such adjustment or readjustment is based. The corporation shall, upon the written request at any time of any holder of Series A Preferred Stock, Series B Preferred Stock, Series B-1 Preferred Stock, Series C Preferred Stock, Series D Preferred Stock, Series E Preferred Stock or Series F Preferred Stock furnish or cause to be furnished to such holder a like certificate setting forth (i) such adjustments and readjustments, (ii) the Series A Conversion Price, Series B Conversion Price, Series B-1 Conversion Price, Series C Conversion Price, Series D Conversion Price, Series E Conversion Price and Series F Conversion Price at the time in effect and
(iii) the number of shares of Common Stock and the amount, if any, of other property which at the time would be received upon the conversion of the Series A Preferred Stock, Series B Preferred Stock, Series B-1 Preferred Stock, Series C Preferred Stock, Series D Preferred Stock, Series E Preferred Stock and Series F Preferred Stock.

(i) NOTICES OF RECORD DATE. In the event that the corporation shall propose at any time: (i) to declare any dividend or distribution upon its Common Stock, whether in cash, property, stock or other securities, whether or not a regular cash dividend and whether or not out of earnings or earned surplus; (ii) to offer for subscription pro rata to the holders of any class or series of its stock any additional shares of stock of any class or series or other rights; (iii) to effect any reclassification or recapitalization of its Common Stock outstanding involving a change in the Common Stock; or (iv) to merge or consolidate with or into any other corporation, or sell, lease or convey all or substantially all of its assets, or to liquidate, dissolve or wind up; then, in connection with each such event, the corporation shall send to the holders of Series A Preferred Stock, Series B Preferred Stock, Series B-1 Preferred Stock, Series C Preferred Stock, Series D Preferred Stock, Series E Preferred Stock and Series F Preferred Stock:

(1) at least twenty (20) days prior written notice of the date on which a record shall be taken for such dividend, distribution or subscription rights (and specifying the date on which the holders of Common Stock shall be entitled thereto) or for determining rights to vote, if any, in respect of the matters referred to in (iii) and (iv) above; and

(2) in the case of the matters referred to in (iii) and
(iv) above, at least twenty (20) days prior written notice of the date when the same shall take place (and specifying the date on which the holders of Common Stock shall be entitled to exchange their Common Stock for securities or other property deliverable upon the occurrence of such event).

(j) ISSUE TAXES. The corporation shall pay any and all issue and other taxes that may be payable in respect of any issue or delivery of shares of Common Stock on conversion of

13.


Series A Preferred Stock, Series B Preferred Stock, Series B-1 Preferred Stock, Series C Preferred Stock, Series D Preferred Stock, Series E Preferred Stock and Series F Preferred Stock pursuant hereto; provided, however, that the corporation shall not be obligated to pay any transfer taxes resulting from any transfer requested by any holder in connection with any such conversion.

(k) RESERVATION OF STOCK ISSUABLE UPON CONVERSION. The corporation shall at all times reserve and keep available out of its authorized but unissued shares of Common Stock, solely for the purpose of effecting the conversion of the shares of the Series A Preferred Stock, Series B Preferred Stock, Series B-1 Preferred Stock, Series C Preferred Stock, Series D Preferred Stock, Series E Preferred Stock and Series F Preferred Stock, such number of its shares of Common Stock as shall from time to time be sufficient to effect the conversion of all outstanding shares of the Series A Preferred Stock, Series B Preferred Stock, Series B- 1 Preferred Stock, Series C Preferred Stock, Series D Preferred Stock, Series E Preferred Stock and Series F Preferred Stock; and if at any time the number of authorized but unissued shares of Common Stock shall not be sufficient to effect the conversion of all then outstanding shares of the Series A Preferred Stock, Series B Preferred Stock, Series B-1 Preferred Stock, Series C Preferred Stock, Series D Preferred Stock, Series E Preferred Stock and Series F Preferred Stock, the corporation will take such corporate action as may, in the opinion of its counsel, be necessary to increase its authorized but unissued shares of Common Stock to such number of shares as shall be sufficient for such purpose, including, without limitation, engaging in best efforts to obtain the requisite stockholder approval of any necessary amendment to these certificate.

(l) FRACTIONAL SHARES. No fractional share shall be issued upon the conversion of any share or shares of Series A Preferred Stock, Series B Preferred Stock, Series B-1 Preferred Stock, Series C Preferred Stock, Series D Preferred Stock, Series E Preferred Stock or Series F Preferred Stock. All shares of Common Stock (including fractions thereof) issuable upon conversion of more than one share of Series A Preferred Stock, Series B Preferred Stock, Series B-1 Preferred Stock, Series C Preferred Stock, Series D Preferred Stock, Series E Preferred Stock or Series F Preferred Stock by a holder thereof shall be aggregated for purposes of determining whether the conversion would result in the issuance of any fractional share. If, after the aforementioned aggregation, the conversion would result in the issuance of a fraction of a share of Common Stock, the corporation shall, in lieu of issuing any fractional share, pay the holder otherwise entitled to such fraction a sum in cash equal to the fair market value of such fraction on the date of conversion (as determined in good faith by the Board of Directors).

(m) NOTICES. Any notice required by the provisions of this
Section 3 to be given to the holder of shares of Series A Preferred Stock, Series B Preferred Stock, Series B-1 Preferred Stock, Series C Preferred Stock, Series D Preferred Stock, Series E Preferred Stock or Series F Preferred Stock shall be deemed given if deposited in the United States mail, postage prepaid, and addressed to each holder of record at the address for such holder appearing on the books of the corporation.

4. VOTING RIGHTS. Each holder of shares of the Series A Preferred Stock, Series B Preferred Stock, Series B-1 Preferred Stock, Series C Preferred Stock, Series D Preferred Stock, Series E Preferred Stock and Series F Preferred Stock shall be entitled to the number of votes equal to the number of shares of Common Stock into which such shares of Series A Preferred Stock, Series B Preferred Stock, Series B-1 Preferred Stock, Series C Preferred Stock, Series D

14.


Preferred Stock, Series E Preferred Stock or Series F Preferred Stock could be converted and shall have voting rights and powers equal to the voting rights and powers of the Common Stock (except as otherwise expressly provided herein or as required by law, voting together with the Common Stock as a single class) and shall be entitled to notice of any stockholders' meeting in accordance with the Bylaws of the corporation. Fractional votes shall not, however, be permitted and any fractional voting rights resulting from the above formula (after aggregating all shares into which shares of Series A Preferred Stock, Series B Preferred Stock, Series B-1 Preferred Stock, Series C Preferred Stock, Series D Preferred Stock, Series E Preferred Stock and Series F Preferred Stock held by each holder could be converted) shall be rounded to the nearest whole number (with one-half being rounded upward). Each holder of Common Stock shall be entitled to one (1) vote for each share of Common Stock held.

5. NO REISSUANCE OF SERIES A PREFERRED STOCK, SERIES B PREFERRED STOCK, SERIES B-1 PREFERRED STOCK, SERIES C PREFERRED STOCK, SERIES D PREFERRED STOCK, SERIES E PREFERRED STOCK OR SERIES F PREFERRED STOCK. No share or shares of
Series A Preferred Stock, Series B Preferred Stock, Series B-1 Preferred Stock, Series C Preferred Stock, Series D Preferred Stock, Series E Preferred Stock or Series F Preferred Stock acquired by the corporation by reason of redemption, purchase, conversion or otherwise shall be reissued, and all such shares shall be canceled, retired and eliminated from the shares that the corporation shall be authorized to issue.

6. COVENANTS. In addition to any other rights provided by law, so long as shares of Series A Preferred Stock, Series B Preferred Stock, Series B-1 Preferred Stock, Series C Preferred Stock, Series D Preferred Stock, Series E Preferred Stock or Series F Preferred Stock are outstanding, the corporation shall not, without first obtaining the affirmative vote or written consent of the holders of not less than a majority of the outstanding shares of the Series A Preferred Stock, Series B Preferred Stock, Series B-1 Preferred Stock, Series C Preferred Stock, Series D Preferred Stock, Series E Preferred Stock and Series F Preferred Stock, voting together as a single class and on an as-converted basis:

(a) amend or repeal any provision of, or add any provision to, this corporation's Certificate of Incorporation if such action would adversely alter or change the preferences, rights, privileges or powers of, or the restrictions provided for the benefit of, the Series A Preferred Stock, Series B Preferred Stock, Series B-1 Preferred Stock, Series C Preferred Stock, Series D Preferred Stock, Series E Preferred Stock or Series F Preferred Stock;

(b) create (by reclassification or otherwise) or issue shares of any class or series of stock having preferences prior to or on a parity with the Series A Preferred Stock, Series B Preferred Stock, Series B-1 Preferred Stock, Series C Preferred Stock, Series D Preferred Stock, Series E Preferred Stock or Series F Preferred Stock with respect to voting, dividends or upon liquidation;

(c) declare or pay a cash dividend on the Common Stock; or

(d) sell, lease, convey or otherwise dispose of or encumber all or substantially all of its property or business or merge into or consolidate with any other corporation immediately after which merger or consolidation (including any series of related transactions) the stockholders of the corporation shall hold less than fifty percent (50%) of the voting power of the surviving corporation.

15.


V.

For the management of the business and for the conduct of the affairs of the corporation, and in further definition, limitation and regulation of the powers of the corporation, of its directors and of its stockholders or any class thereof, as the case may be, it is further provided that:

1. The management of the business and the conduct of the affairs of the corporation shall be vested in its Board of Directors. The number of directors which shall constitute the whole Board of Directors shall be fixed exclusively by one or more resolutions adopted by the Board of Directors.

2. Subject to the rights of the holders of any series of Preferred Stock to elect additional directors under specified circumstances, following the closing of the initial public offering pursuant to an effective registration statement under the Securities Act of 1933, as amended (the "1933 Act"), covering the offer and sale of Common Stock to the public (the "Initial Public Offering"), the directors shall be divided into three classes designated as Class I , Class II and Class III, respectively. Directors shall be assigned to each class in accordance with a resolution or resolutions adopted by the Board of Directors. At the first annual meeting of stockholders following the closing of the Initial Public Offering, the term of office of the Class I directors shall expire and Class I directors shall be elected for a full term of three years. At the second annual meeting of stockholders following the Closing of the Initial Public Offering, the term of office of the Class II directors shall expire and Class II directors shall be elected for a full term of three years. At the third annual meeting of stockholders following the Closing of the Initial Public Offering, the term of office of the Class III directors shall expire and Class III directors shall be elected for a full term of three years. At each succeeding annual meeting of stockholders, directors shall be elected for a full term of three years to succeed the directors of the class whose terms expire at such annual meeting.

Notwithstanding the foregoing provisions of this Article, each director shall serve until his successor is duly elected and qualified or until his death, resignation or removal. No decrease in the number of directors constituting the Board of Directors shall shorten the term of any incumbent director.

3. Subject to the rights of the holders of any series of Preferred Stock, the Board of Directors or any individual director may be removed from office at any time with cause by the affirmative vote of the holders of a majority of the voting power of all of the then outstanding stock of voting stock of the Corporation, entitled to vote at an election of directors (the "Voting Stock").

4. Subject to the rights of the holders of any series of Preferred Stock, any vacancies on the Board of Directors resulting from death, resignation, disqualification, removal or other causes and any newly created directorships resulting from any increase in the number of directors, shall, unless the Board of Directors determines by resolution that any such vacancies or newly created directorships shall be filled by the stockholders, except as otherwise provided by law, be filled only by the affirmative vote of a majority of the directors then in office, even though less than a quorum of the Board of Directors, and not by the stockholders. Any director

16.


elected in accordance with the preceding sentence shall hold office for the remainder of the full term of the director for which the vacancy was created or occurred and until such director's successor shall have been elected and qualified.

5. In the event that Section 2115(a) of the California Corporations Code is applicable to this corporation, then the following shall apply:

(a) Every stockholder entitled to vote in any election of directors of this corporation may cumulate such stockholder's votes and give one candidate a number of votes equal to the number of directors to be elected multiplied by the number of votes to which the stockholder's shares are otherwise entitled, or distribute the stockholder's votes on the same principle among as many candidates as such stockholder thinks fit;

(b) No stockholder, however, may cumulate such stockholder's votes for one or more candidates unless (i) the names of such candidates have been properly placed in nomination, in accordance with the Bylaws of the corporation, prior to the voting, (ii) the stockholder has given advance notice to the corporation of the intention to cumulative votes pursuant to the Bylaws, and (iii) the stockholder has given proper notice to the other stockholders at the meeting, prior to voting, of such stockholder's intention to cumulate such stockholder's votes; and

(c) If any stockholder has given proper notice, all stockholders may cumulate their votes for any candidates who have been properly placed in nomination. The candidates receiving the highest number of votes of the shares entitled to be voted for them up to the number of directors to be elected by such shares shall be declared elected.

6. Subject to paragraph (h) of Section 43 of the Bylaws, the Bylaws may be altered or amended or new Bylaws adopted by the affirmative vote of at least sixty-six and two-thirds percent (66-2/3%) of the voting power of all of the then-outstanding shares of the Voting Stock. The Board of Directors shall also have the power to adopt, amend or repeal Bylaws.

(a) The directors of the corporation need not be elected by written ballot unless the Bylaws so provide.

(b) No action shall be taken by the stockholders of the corporation except at an annual or special meeting of stockholders called in accordance with the Bylaws or by written consent of the stockholders in accordance with the Bylaws prior to the closing of the Initial Public Offering and following the closing of the Initial Public Offering no action shall be taken by the stockholders by written consent.

(c) Advance notice of stockholder nominations for the election of directors and of business to be brought by stockholders before any meeting of the stockholders of the corporation shall be given in the manner provided in the Bylaws of the corporation.

VI.

1. A director of the corporation shall not be personally liable to the corporation or its stockholders for monetary damages for any breach of fiduciary duty as a director, except for

17.


liability (i) for any breach of the director's duty of loyalty to the corporation or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law (iii) under
Section 174 of the Delaware General Corporation Law, or (iv) for any transaction from which the director derived an improper personal benefit. If the Delaware General Corporation Law is amended after approval by the stockholders of this Article to authorize corporate action further eliminating or limiting the personal liability of directors, then the liability of a director shall be eliminated or limited to the fullest extent permitted by the Delaware General Corporation Law, as so amended.

2. Any repeal or modification of this Article VI shall be prospective and shall not affect the rights under this Article VI in effect at the time of the alleged occurrence of any act or omission to act giving rise to liability or indemnification.

VII.

1. The corporation reserves the right to amend, alter, change or repeal any provision contained in this Certificate of Incorporation, in the manner now or hereafter prescribed by statute, except as provided in paragraph B. of this Article VII, and all rights conferred upon the stockholders herein are granted subject to this reservation.

2. Notwithstanding any other provisions of this Certificate of Incorporation or any provision of law which might otherwise permit a lesser vote or no vote, but in addition to any affirmative vote of the holders of any particular class or series of the Voting Stock required by law, this Certificate of Incorporation or any Preferred Stock Designation, the affirmative vote of the holders of at least sixty-six and two-thirds percent (66-2/3%) of the voting power of all of the then-outstanding shares of the Voting Stock, voting together as a single class, shall be required to alter, amend or repeal Articles V, VI and VII.

SECTION 5. ANNUAL MEETING.

(a) The annual meeting of the stockholders of the corporation, for the purpose of election of directors and for such other business as may lawfully come before it, shall be held on such date and at such time as may be designated from time to time by the Board of Directors.

(b) At an annual meeting of the stockholders, only such business shall be conducted as shall have been properly brought before the meeting.

1.


brought before the meeting by or at the direction of the Board of Directors, or
(C) otherwise properly brought before the meeting by a stockholder. For business to be properly brought before an annual meeting by a stockholder, the stockholder must have given timely notice thereof in writing to the Secretary of the corporation. To be timely, a stockholder's notice must be delivered to or mailed and received at the principal executive offices of the corporation not later than the close of business on the sixtieth (60th) day nor earlier than the close of business on the ninetieth (90th) day prior to the first anniversary of the preceding year's annual meeting; provided, however, that in the event that no annual meeting was held in the previous year or the date of the annual meeting has been changed by more than thirty (30) days from the date contemplated at the time of the previous year's proxy statement, notice by the stockholder to be timely must be so received not earlier than the close of business on the ninetieth (90th) day prior to such annual meeting and not later than the close of business on the later of the sixtieth (60th) day prior to such annual meeting or, in the event public announcement of the date of such annual meeting is first made by the corporation fewer than seventy (70) days prior to the date of such annual meeting, the close of business on the tenth (10th) day following the day on which public announcement of the date of such meeting is first made by the corporation. A stockholder's notice to the Secretary shall set forth as to each matter the stockholder proposes to bring before the annual meeting: (i) a brief description of the business desired to be brought before the annual meeting and the reasons for conducting such business at the annual meeting, (ii) the name and address, as they appear on the corporation's books, of the stockholder proposing such business, (iii) the class and number of shares of the corporation which are beneficially owned by the stockholder, (iv) any material interest of the stockholder in such business and (v) any other information that is required to be provided by the stockholder pursuant to Regulation 14A under the Securities Exchange Act of 1934, as amended (the "1934 Act"), in his capacity as a proponent to a stockholder proposal. Notwithstanding the foregoing, in order to include information with respect to a stockholder proposal in the proxy statement and form of proxy for a stockholder's meeting, stockholders must provide notice as required by the regulations promulgated under the 1934 Act. Notwithstanding anything in these Bylaws to the contrary, no business shall be conducted at any annual meeting except in accordance with the procedures set forth in this paragraph (b). The chairman of the annual meeting shall, if the facts warrant, determine and declare at the meeting that business was not properly brought before the meeting and in accordance with the provisions of this paragraph (b), and, if he should so determine, he shall so declare at the meeting that any such business not properly brought before the meeting shall not be transacted.

(c) Only persons who are nominated in accordance with the procedures set forth in this paragraph (c) shall be eligible for election as directors. Nominations of persons for election to the Board of Directors of the corporation may be made at a meeting of stockholders by or at the direction of the Board of Directors or by any stockholder of the corporation entitled to vote in the election of directors at the meeting who complies with the notice procedures set forth in this paragraph (c). Such nominations, other than those made by or at the direction of the Board of Directors, shall be made pursuant to timely notice in writing to the Secretary of the corporation in accordance with the provisions of paragraph (b) of this Section 5. Such stockholder's notice shall set forth

2.


person, (D) a description of all arrangements or understandings between the stockholder and each nominee and any other person or persons (naming such person or persons) pursuant to which the nominations are to be made by the stockholder, and (E) any other information relating to such person that is required to be disclosed in solicitations of proxies for election of directors, or is otherwise required, in each case pursuant to Regulation 14A under the 1934 Act (including without limitation such person's written consent to being named in the proxy statement, if any, as a nominee and to serving as a director if elected); and
(ii) as to such stockholder giving notice, the information required to be provided pursuant to paragraph (b) of this Section 5. At the request of the Board of Directors, any person nominated by a stockholder for election as a director shall furnish to the Secretary of the corporation that information required to be set forth in the stockholder's notice of nomination which pertains to the nominee. No person shall be eligible for election as a director of the corporation unless nominated in accordance with the procedures set forth in this paragraph (c). The chairman of the meeting shall, if the facts warrant, determine and declare at the meeting that a nomination was not made in accordance with the procedures prescribed by these Bylaws, and if he should so determine, he shall so declare at the meeting, and the defective nomination shall be disregarded.

(d) For purposes of this Section 5, "public announcement" shall mean disclosure in a press release reported by the Dow Jones News Service, Associated Press or comparable national news service or in a document publicly filed by the corporation with the Securities and Exchange Commission pursuant to Section 13, 14 or 15(d) of the 1934 Act.

SECTION 6. SPECIAL MEETINGS.

(a) Special meetings of the stockholders of the corporation may be called, for any purpose or purposes, by (i) the Chairman of the Board of Directors, (ii) the Chief Executive Officer, (iii) the Board of Directors pursuant to a resolution adopted by a majority of the total number of authorized directors (whether or not there exist any vacancies in previously authorized directorships at the time any such resolution is presented to the Board of Directors for adoption) or (iv) for so long as Section 2115(a) of the California Corporations Code is applicable to the corporation, by the holders of shares entitled to cast not less than fifty percent (50%) of the votes at the meeting, and shall be held at such place, on such date, and at such time as the Board of Directors, shall fix.

(b) If a special meeting is called by any person or persons other than the Board of Directors, the request shall be in writing, specifying the general nature of the business proposed to be transacted, and shall be delivered personally or sent by registered mail or by telegraphic or other facsimile transmission to the Chairman of the Board of Directors, the Chief Executive Officer, or the Secretary of the corporation. No business may be transacted at such special meeting otherwise than specified in such notice. The Board of Directors shall determine the time and place of such special meeting, which shall be held not less than thirty-five (35) nor more than one hundred twenty
(120) days after the date of the receipt of the request. Upon determination of the time and place of the meeting, the officer receiving the request shall cause notice to be given to the stockholders entitled to vote, in accordance with the provisions of Section 7 of these Bylaws. If the notice is not given within sixty (60) days after the receipt of the request, the person or persons requesting the meeting may set the time and place of the meeting and give the notice. Nothing contained in this paragraph (b) shall be construed as limiting,

3.


fixing, or affecting the time when a meeting of stockholders called by action of the Board of Directors may be held.

SECTION 7. NOTICE OF MEETINGS. Except as otherwise provided by law or the Certificate of Incorporation, written notice of each meeting of stockholders shall be given not less than ten (10) nor more than sixty (60) days before the date of the meeting to each stockholder entitled to vote at such meeting, such notice to specify the place, date and hour and purpose or purposes of the meeting. Notice of the time, place and purpose of any meeting of stockholders may be waived in writing, signed by the person entitled to notice thereof, either before or after such meeting, and will be waived by any stockholder by his attendance thereat in person or by proxy, except when the stockholder attends a meeting for the express purpose of objecting, at the beginning of the meeting, to the transaction of any business because the meeting is not lawfully called or convened. Any stockholder so waiving notice of such meeting shall be bound by the proceedings of any such meeting in all respects as if due notice thereof had been given.

SECTION 8. QUORUM. At all meetings of stockholders, except where otherwise provided by statute or by the Certificate of Incorporation, or by these Bylaws, the presence, in person or by proxy duly authorized, of the holders of a majority of the outstanding shares of stock entitled to vote shall constitute a quorum for the transaction of business. In the absence of a quorum, any meeting of stockholders may be adjourned, from time to time, either by the chairman of the meeting or by vote of the holders of a majority of the shares represented thereat, but no other business shall be transacted at such meeting. The stockholders present at a duly called or convened meeting, at which a quorum is present, may continue to transact business until adjournment, notwithstanding the withdrawal of enough stockholders to leave less than a quorum. Except as otherwise provided by law, the Certificate of Incorporation or these Bylaws, all action taken by the holders of a majority of the vote cast, excluding abstentions, at any meeting at which a quorum is present shall be valid and binding upon the corporation; provided, however, that directors shall be elected by a plurality of the votes of the shares present in person or represented by proxy at the meeting and entitled to vote on the election of directors. Where a separate vote by a class or classes or series is required, except where otherwise provided by the statute or by the Certificate of Incorporation or these Bylaws, a majority of the outstanding shares of such class or classes or series, present in person or represented by proxy, shall constitute a quorum entitled to take action with respect to that vote on that matter and, except where otherwise provided by the statute or by the Certificate of Incorporation or these Bylaws, the affirmative vote of the majority (plurality, in the case of the election of directors) of the votes cast, including abstentions, by the holders of shares of such class or classes or series shall be the act of such class or classes or series.

SECTION 9. ADJOURNMENT AND NOTICE OF ADJOURNED MEETINGS. Any meeting of stockholders, whether annual or special, may be adjourned from time to time either by the chairman of the meeting or by the vote of a majority of the shares casting votes, excluding abstentions. When a meeting is adjourned to another time or place, notice need not be given of the adjourned meeting if the time and place thereof are announced at the meeting at which the adjournment is taken. At the adjourned meeting, the corporation may transact any business which might have been transacted at the original meeting. If the adjournment is for more than thirty (30) days or if after the adjournment a new record date is fixed for the adjourned meeting,

4.


a notice of the adjourned meeting shall be given to each stockholder of record entitled to vote at the meeting.

SECTION 10. VOTING RIGHTS. For the purpose of determining those stockholders entitled to vote at any meeting of the stockholders, except as otherwise provided by law, only persons in whose names shares stand on the stock records of the corporation on the record date, as provided in Section 12 of these Bylaws, shall be entitled to vote at any meeting of stockholders. Every person entitled to vote or execute consents shall have the right to do so either in person or by an agent or agents authorized by a proxy granted in accordance with Delaware law. An agent so appointed need not be a stockholder. No proxy shall be voted after three (3) years from its date of creation unless the proxy provides for a longer period.

SECTION 11. JOINT OWNERS OF STOCK. If shares or other securities having voting power stand of record in the names of two (2) or more persons, whether fiduciaries, members of a partnership, joint tenants, tenants in common, tenants by the entirety, or otherwise, or if two (2) or more persons have the same fiduciary relationship respecting the same shares, unless the Secretary is given written notice to the contrary and is furnished with a copy of the instrument or order appointing them or creating the relationship wherein it is so provided, their acts with respect to voting shall have the following effect: (a) if only one (1) votes, his act binds all; (b) if more than one (1) votes, the act of the majority so voting binds all; (c) if more than one (1) votes, but the vote is evenly split on any particular matter, each faction may vote the securities in question proportionally, or may apply to the Delaware Court of Chancery for relief as provided in the General Corporation Law of Delaware, Section 217(b). If the instrument filed with the Secretary shows that any such tenancy is held in unequal interests, a majority or even-split for the purpose of subsection (c) shall be a majority or even-split in interest.

SECTION 12. LIST OF STOCKHOLDERS. The Secretary shall prepare and make, at least ten (10) days before every meeting of stockholders, a complete list of the stockholders entitled to vote at said meeting, arranged in alphabetical order, showing the address of each stockholder and the number of shares registered in the name of each stockholder. Such list shall be open to the examination of any stockholder, for any purpose germane to the meeting, during ordinary business hours, for a period of at least ten (10) days prior to the meeting, either at a place within the city where the meeting is to be held, which place shall be specified in the notice of the meeting, or, if not specified, at the place where the meeting is to be held. The list shall be produced and kept at the time and place of meeting during the whole time thereof and may be inspected by any stockholder who is present.

SECTION 13. ACTION WITHOUT MEETING.

(a) Unless otherwise provided in the Certificate of Incorporation, any action required by statute to be taken at any annual or special meeting of the stockholders, or any action which may be taken at any annual or special meeting of the stockholders, may be taken without a meeting, without prior notice and without a vote, if a consent in writing, setting forth the action so taken, shall be signed by the holders of outstanding stock having not less than the minimum number of votes that would be necessary to authorize or take such action at a meeting at which all shares entitled to vote thereon were present and voted.

5.


(b) Every written consent shall bear the date of signature of each stockholder who signs the consent, and no written consent shall be effective to take the corporate action referred to therein unless, within sixty (60) days of the earliest dated consent delivered to the corporation in the manner herein required, written consents signed by a sufficient number of stockholders to take action are delivered to the corporation by delivery to its registered office in the State of Delaware, its principal place of business or an officer or agent of the corporation having custody of the book in which proceedings of meetings of stockholders are recorded. Delivery made to a corporation's registered office shall be by hand or by certified or registered mail, return receipt requested.

(c) Prompt notice of the taking of the corporate action without a meeting by less than unanimous written consent shall be given to those stockholders who have not consented in writing. If the action which is consented to is such as would have required the filing of a certificate under any section of the General Corporation Law of the State of Delaware if such action had been voted on by stockholders at a meeting thereof, then the certificate filed under such section shall state, in lieu of any statement required by such section concerning any vote of stockholders, that written consent has been given in accordance with
Section 228 of the General Corporation Law of Delaware.

(d) Notwithstanding the foregoing, no such action by written consent may be taken following the closing of the initial public offering pursuant to an effective registration statement under the Securities Act of 1933, as amended (the "1933 Act"), covering the offer and sale of Common Stock of the corporation (the "Initial Public Offering").

SECTION 14. ORGANIZATION.

(a) At every meeting of stockholders, the Chairman of the Board of Directors, or, if a Chairman has not been appointed or is absent, the President, or, if the President is absent, a chairman of the meeting chosen by a majority in interest of the stockholders entitled to vote, present in person or by proxy, shall act as chairman. The Secretary, or, in his absence, an Assistant Secretary directed to do so by the President, shall act as secretary of the meeting.

(b) The Board of Directors of the corporation shall be entitled to make such rules or regulations for the conduct of meetings of stockholders as it shall deem necessary, appropriate or convenient. Subject to such rules and regulations of the Board of Directors, if any, the chairman of the meeting shall have the right and authority to prescribe such rules, regulations and procedures and to do all such acts as, in the judgment of such chairman, are necessary, appropriate or convenient for the proper conduct of the meeting, including, without limitation, establishing an agenda or order of business for the meeting, rules and procedures for maintaining order at the meeting and the safety of those present, limitations on participation in such meeting to stockholders of record of the corporation and their duly authorized and constituted proxies and such other persons as the chairman shall permit, restrictions on entry to the meeting after the time fixed for the commencement thereof, limitations on the time allotted to questions or comments by participants and regulation of the opening and closing of the polls for balloting on matters which are to be voted on by ballot.

SECTION 15. NUMBER AND TERM OF OFFICE. The authorized number of directors of the corporation shall be fixed in accordance with the Certificate of Incorporation.

Subject to the rights of the holders of any series of Preferred Stock to elect additional directors under specified circumstances, following the closing of the Initial Public Offering, the directors shall be divided into three classes designated as Class I, Class II and Class III, respectively. Directors shall be assigned to each class in accordance with a resolution or resolutions adopted by the Board of Directors. At the first annual meeting of stockholders following the closing of the Initial Public Offering, the term of office of the Class I directors shall expire and Class I directors shall be elected for a full term of three years.

SECTION 18. VACANCIES. Unless otherwise provided in the Certificate of Incorporation, any vacancies on the Board of Directors resulting from death, resignation, disqualification, removal or other causes and any newly created directorships resulting from any increase in the number of directors shall, unless the Board of Directors determines by resolution that any such vacancies or newly created directorships shall be filled by stockholders, be filled only by the affirmative vote of a majority of the directors then in office, even though less than a quorum of the Board of Directors. Any director elected in accordance with the preceding sentence shall hold office for the remainder of the full term of the director for which the vacancy was created or occurred and until such director's successor shall have been elected and qualified. A vacancy in the Board of Directors shall be deemed to exist under this Bylaw in the case of the death, removal or resignation of any director.

SECTION 19. RESIGNATION.

If no such specification is made, it shall be deemed effective at the pleasure of the Board of Directors. When one or more directors shall resign from the Board of Directors, effective at a future date, a majority of the directors then in office, including those who have so resigned, shall have power to fill such vacancy or vacancies, the vote thereon to take effect when such resignation or resignations shall become effective, and each Director so chosen shall hold office for the unexpired portion of the term of the Director whose place shall be vacated and until his successor shall have been duly elected and qualified.

SECTION 20. REMOVAL.

Subject to the rights of the holders of any series of Preferred Stock, no director shall be removed without cause.

Section A(3)(a) above shall no longer apply and subject to the rights of the holders of any series of Preferred Stock, no director shall be removed without cause.

Notice of any meeting may be waived in writing at any time before or after the meeting and will be waived by any director by attendance thereat, except when the director attends the meeting for the express purpose of objecting, at the beginning of the meeting, to the transaction of any business because the meeting is not lawfully called or convened.

(f) WAIVER OF NOTICE. The transaction of all business at any meeting of the Board of Directors, or any committee thereof, however called or noticed, or wherever held, shall be as valid as though had at a meeting duly held after regular call and notice, if a quorum be present and if, either before or after the meeting, each of the directors not present shall sign a written waiver of notice. All such waivers shall be filed with the corporate records or made a part of the minutes of the meeting.

SECTION 22. QUORUM AND VOTING.

(a) Unless the Certificate of Incorporation requires a greater number and except with respect to indemnification questions arising under Section 43 hereof, for which a quorum shall be one-third of the exact number of directors fixed from time to time in accordance with the Certificate of Incorporation, a quorum of the Board of Directors shall consist of a majority of the exact number of directors fixed from time to time by the Board of Directors in accordance with the Certificate of Incorporation; provided, however, at any meeting, whether a quorum be present or otherwise, a majority of the directors present may adjourn from time to time until the time fixed for the next regular meeting of the Board of Directors, without notice other than by announcement at the meeting.

(b) At each meeting of the Board of Directors at which a quorum is present, all questions and business shall be determined by the affirmative vote of a majority of the directors present, unless a different vote be required by law, the Certificate of Incorporation or these Bylaws.

SECTION 23. ACTION WITHOUT MEETING. Unless otherwise restricted by the Certificate of Incorporation or these Bylaws, any action required or permitted to be taken at any meeting of the Board of Directors or of any committee thereof may be taken without a meeting, if all members of the Board of Directors or committee, as the case may be, consent thereto in writing, and such writing or writings are filed with the minutes of proceedings of the Board of Directors or committee.

SECTION 24. FEES AND COMPENSATION. Directors shall be entitled to such compensation for their services as may be approved by the Board of Directors, including, if so approved, by resolution of the Board of Directors, a fixed sum and expenses of attendance, if

The membership of a committee member shall terminate on the date of his death or voluntary resignation from the committee or from the Board of Directors. The Board of Directors may at any time for any reason remove any individual committee member and the Board of Directors may fill any committee vacancy created by death, resignation, removal or increase in the number of members of the committee. The Board of Directors may designate one or more directors as alternate members of any committee, who may replace any absent or disqualified member at any meeting of the committee, and, in addition, in the absence or disqualification of any member of a committee, the member or members thereof present at any meeting and not disqualified from voting, whether or not he or they constitute a quorum, may unanimously appoint another member of the Board of Directors to act at the meeting in the place of any such absent or disqualified member.

(d) MEETINGS. Unless the Board of Directors shall otherwise provide, regular meetings of the Executive Committee or any other committee appointed pursuant to this Section 25 shall be held at such times and places as are determined by the Board of Directors, or by any such committee, and when notice thereof has been given to each member of such committee, no further notice of such regular meetings need be given thereafter. Special meetings of any such committee may be held at any place which has been determined from time to time by such committee, and may be called by any director who is a member of such committee, upon

10.


written notice to the members of such committee of the time and place of such special meeting given in the manner provided for the giving of written notice to members of the Board of Directors of the time and place of special meetings of the Board of Directors. Notice of any special meeting of any committee may be waived in writing at any time before or after the meeting and will be waived by any director by attendance thereat, except when the director attends such special meeting for the express purpose of objecting, at the beginning of the meeting, to the transaction of any business because the meeting is not lawfully called or convened.

Unless otherwise specifically determined by the Board of Directors or otherwise required by law, promissory notes, deeds of trust, mortgages and other evidences of indebtedness of the corporation, and other corporate instruments or documents requiring the corporate seal, and certificates of shares of stock owned by the corporation, shall be executed, signed or endorsed by the Chairman of the Board of Directors, or the President or any Vice President, and by the Secretary or Treasurer or any Assistant Secretary or Assistant Treasurer.

SHARES OF STOCK

SECTION 34. FORM AND EXECUTION OF CERTIFICATES. Certificates for the shares of stock of the corporation shall be in such form as is consistent with the Certificate of Incorporation and applicable law. Every holder of stock in the corporation shall be entitled to have a certificate signed by or in the name of the corporation by the Chairman of the Board of Directors, or the President or any Vice President and by the Treasurer or Assistant Treasurer or the Secretary or Assistant Secretary, certifying the number of shares owned by him in the corporation. Any or all of the signatures on the certificate may be facsimiles. In case any officer, transfer agent, or registrar who has signed or whose facsimile signature has been placed upon a certificate shall have ceased to be such officer, transfer agent, or registrar before such certificate is issued, it may be issued with the same effect as if he were such officer, transfer agent, or registrar at the date of issue. Each certificate shall state upon the face or back thereof, in full or in summary, all of the powers, designations, preferences, and rights, and the limitations or restrictions of the shares authorized to be issued or shall, except as otherwise required by law, set forth on the face or back a statement that the corporation will furnish without charge to each stockholder who so requests the powers, designations, preferences and relative, participating, optional, or other special rights of each class of stock or series thereof and the qualifications, limitations or restrictions of such preferences and/or rights. Within a reasonable time after the issuance or transfer of uncertificated stock, the corporation shall send to the registered owner thereof a written notice containing the information required to be set forth or stated on certificates pursuant to this section or otherwise required by law or with respect to this section a statement that the corporation will furnish without charge to each stockholder who so requests the powers, designations, preferences and relative participating, optional or other special rights of each class of stock or series thereof and the qualifications, limitations or restrictions of such preferences and/or rights. Except as otherwise expressly provided by law, the rights and obligations of the holders of certificates representing stock of the same class and series shall be identical.

SECTION 35. LOST CERTIFICATES. A new certificate or certificates shall be issued in place of any certificate or certificates theretofore issued by the corporation alleged to have been lost, stolen, or destroyed, upon the making of an affidavit of that fact by the person claiming the certificate of stock to be lost, stolen, or destroyed. The corporation may require, as a condition precedent to the issuance of a new certificate or certificates, the owner of such lost, stolen, or destroyed certificate or certificates, or his legal representative, to advertise the same in such manner as it shall require or to give the corporation a surety bond in such form and amount as it may direct as indemnity against any claim that may be made against the corporation with respect to the certificate alleged to have been lost, stolen, or destroyed.

SECTION 36. TRANSFERS.

(a) Transfers of record of shares of stock of the corporation shall be made only upon its books by the holders thereof, in person or by attorney duly authorized, and upon the surrender of a properly endorsed certificate or certificates for a like number of shares.

(b) The corporation shall have power to enter into and perform any agreement with any number of stockholders of any one or more classes of stock of the corporation to restrict the transfer of shares of stock of the corporation of any one or more classes owned by such stockholders in any manner not prohibited by the General Corporation Law of Delaware.

SECTION 37. FIXING RECORD DATES.

(a) In order that the corporation may determine the stockholders entitled to notice of or to vote at any meeting of stockholders or any adjournment thereof, the Board of Directors may fix, in advance, a record date, which record date shall not precede the date upon which the resolution fixing the record date is adopted by the Board of Directors, and which record date shall not be more than sixty (60) nor less than ten (10) days before the date of such meeting. If no record date is fixed by the Board of Directors, the record date for determining stockholders entitled to notice of or to vote at a meeting of stockholders shall be at the close of business on the day next preceding the day on which notice is given, or if notice is waived, at the close of business on the day next preceding the day on which the meeting is held. A determination of stockholders of record entitled to notice of or to vote at a meeting of stockholders shall apply to any adjournment of the meeting; provided, however, that the Board of Directors may fix a new record date for the adjourned meeting.

(b) Prior to the Initial Public Offering, in order that the corporation may determine the stockholders entitled to consent to corporate action in writing without a meeting, the Board of Directors may fix a record date, which record date shall not precede the date upon which the resolution fixing the record date is adopted by the Board of Directors, and which date shall not be more than ten
(10) days after the date upon which the resolution fixing the record date is adopted by the Board of Directors. Any stockholder of record seeking to have the stockholders authorize or take corporate action by written consent shall, by written notice to the Secretary, request the Board of Directors to fix a record date. The Board of Directors shall promptly, but in all events within ten (10) days after the date on which such a request is received, adopt a resolution fixing the record date. If no record date has been fixed by the Board of Directors within ten (10) days of the date on which such a request is received, the record date for determining stockholders entitled to consent to corporate action in writing without a meeting, when no prior action by the Board of Directors is required by applicable law, shall be the first date on which a signed written consent setting forth the action taken or proposed to be taken is delivered to the corporation by delivery to its registered office in the State of Delaware, its principal place of business or an officer or agent of the corporation having custody of the book in which proceedings of meetings of stockholders are recorded. Delivery made to the corporation's registered office shall be by hand or by certified or registered mail, return receipt requested. If no record date has been fixed by the Board of Directors and prior action by the Board of Directors is required by law, the record date for determining stockholders entitled to consent to corporate action in writing without a meeting shall be at the close of business on the day on which the Board of Directors adopts the resolution taking such prior action.

(c) In order that the corporation may determine the stockholders entitled to receive payment of any dividend or other distribution or allotment of any rights or the stockholders entitled to exercise any rights in respect of any change, conversion or exchange of stock, or for the purpose of any other lawful action, the Board of Directors may fix, in advance, a

15.


record date, which record date shall not precede the date upon which the resolution fixing the record date is adopted, and which record date shall be not more than sixty (60) days prior to such action. If no record date is fixed, the record date for determining stockholders for any such purpose shall be at the close of business on the day on which the Board of Directors adopts the resolution relating thereto.

SECTION 38. REGISTERED STOCKHOLDERS. The corporation shall be entitled to recognize the exclusive right of a person registered on its books as the owner of shares to receive dividends, and to vote as such owner, and shall not be bound to recognize any equitable or other claim to or interest in such share or shares on the part of any other person whether or not it shall have express or other notice thereof, except as otherwise provided by the laws of Delaware.

SECTION 39. EXECUTION OF OTHER SECURITIES. All bonds, debentures and other corporate securities of the corporation, other than stock certificates (covered in Section 34), may be signed by the Chairman of the Board of Directors, the President or any Vice President, or such other person as may be authorized by the Board of Directors, and the corporate seal impressed thereon or a facsimile of such seal imprinted thereon and attested by the signature of the Secretary or an Assistant Secretary, or the Chief Financial Officer or Treasurer or an Assistant Treasurer; provided, however, that where any such bond, debenture or other corporate security shall be authenticated by the manual signature, or where permissible facsimile signature, of a trustee under an indenture pursuant to which such bond, debenture or other corporate security shall be issued, the signatures of the persons signing and attesting the corporate seal on such bond, debenture or other corporate security may be the imprinted facsimile of the signatures of such persons. Interest coupons appertaining to any such bond, debenture or other corporate security, authenticated by a trustee as aforesaid, shall be signed by the Treasurer or an Assistant Treasurer of the corporation or such other person as may be authorized by the Board of Directors, or bear imprinted thereon the facsimile signature of such person. In case any officer who shall have signed or attested any bond, debenture or other corporate security, or whose facsimile signature shall appear thereon or on any such interest coupon, shall have ceased to be such officer before the bond, debenture or other corporate security so signed or attested shall have been delivered, such bond, debenture or other corporate security nevertheless may be adopted by the corporation and issued and delivered as though the person who signed the same or whose facsimile signature shall have been used thereon had not ceased to be such officer of the corporation.

SECTION 41. DIVIDEND RESERVE. Before payment of any dividend, there may be set aside out of any funds of the corporation available for dividends such sum or sums as the Board of Directors from time to time, in their absolute discretion, think proper as a reserve or reserves to meet contingencies, or for equalizing dividends, or for repairing or maintaining any property of the corporation, or for such other purpose as the Board of Directors shall think conducive to the interests of the corporation, and the Board of Directors may modify or abolish any such reserve in the manner in which it was created.

SECTION 42. FISCAL YEAR. The fiscal year of the corporation shall be fixed by resolution of the Board of Directors.

ARTICLE XI

INDEMNIFICATION

SECTION 43. INDEMNIFICATION OF DIRECTORS, EXECUTIVE OFFICERS, OTHER OFFICERS, EMPLOYEES AND OTHER AGENTS.

(a) DIRECTORS AND EXECUTIVE OFFICERS. The corporation shall indemnify its directors and executive officers (for the purposes of this Article XI, "executive officers" shall have the meaning defined in Rule 3b-7 promulgated under the 1934 Act) to the fullest extent not prohibited by the Delaware General Corporation Law; provided, however, that the corporation may modify the extent of such indemnification by individual contracts with its directors or executive officer; and, provided, further, that the corporation shall not be required to indemnify any director or executive officer in connection with any proceeding (or part thereof) initiated by such person unless (i) such indemnification is expressly required to be made by law, (ii) the proceeding was authorized by the Board of Directors of the corporation, (iii) such indemnification is provided by the corporation, in its sole discretion, pursuant to the powers vested in the corporation under the Delaware General Corporation Law or (iv) such indemnification is required to be made under subsection (d).

(b) OTHER OFFICERS, EMPLOYEES AND OTHER AGENTS. The corporation shall have power to indemnify its other officers, employees and other agents as set forth in the Delaware General Corporation Law.

17.


(c) EXPENSES. The corporation shall advance to any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, by reason of the fact that he is or was a director or executive officer, of the corporation, or is or was serving at the request of the corporation as a director or executive officer of another corporation, partnership, joint venture, trust or other enterprise, prior to the final disposition of the proceeding, promptly following request therefor, all expenses incurred by any director or executive officer in connection with such proceeding upon receipt of an undertaking by or on behalf of such person to repay said amounts if it should be determined ultimately that such person is not entitled to be indemnified under this Bylaw or otherwise.

Notwithstanding the foregoing, unless otherwise determined pursuant to paragraph
(e) of this Bylaw, no advance shall be made by the corporation to an executive officer of the corporation (except by reason of the fact that such executive officer is or was a director of the corporation in which event this paragraph shall not apply) in any action, suit or proceeding, whether civil, criminal, administrative or investigative, if a determination is reasonably and promptly made (i) by the Board of Directors by a majority vote of a quorum consisting of directors who were not parties to the proceeding, or (ii) if such quorum is not obtainable, or, even if obtainable, a quorum of disinterested directors so directs, by independent legal counsel in a written opinion, that the facts known to the decision-making party at the time such determination is made demonstrate clearly and convincingly that such person acted in bad faith or in a manner that such person did not believe to be in or not opposed to the best interests of the corporation.

(d) ENFORCEMENT. Without the necessity of entering into an express contract, all rights to indemnification and advances to directors and executive officers under this Bylaw shall be deemed to be contractual rights and be effective to the same extent and as if provided for in a contract between the corporation and the director or executive officer. Any right to indemnification or advances granted by this Bylaw to a director or executive officer shall be enforceable by or on behalf of the person holding such right in any court of competent jurisdiction if (i) the claim for indemnification or advances is denied, in whole or in part, or (ii) no disposition of such claim is made within ninety (90) days of request therefor. The claimant in such enforcement action, if successful in whole or in part, shall be entitled to be paid also the expense of prosecuting his claim. In connection with any claim for indemnification, the corporation shall be entitled to raise as a defense to any such action that the claimant has not met the standards of conduct that make it permissible under the Delaware General Corporation Law for the corporation to indemnify the claimant for the amount claimed. In connection with any claim by an executive officer of the corporation (except in any action, suit or proceeding, whether civil, criminal, administrative or investigative, by reason of the fact that such executive officer is or was a director of the corporation) for advances, the corporation shall be entitled to raise a defense as to any such action clear and convincing evidence that such person acted in bad faith or in a manner that such person did not believe to be in or not opposed to the best interests of the corporation, or with respect to any criminal action or proceeding that such person acted without reasonable cause to believe that his conduct was lawful. Neither the failure of the corporation (including its Board of Directors, independent legal counsel or its stockholders) to have made a determination prior to the commencement of such action that indemnification of the claimant is proper in the circumstances because he has met the applicable standard of conduct set forth in the Delaware General Corporation Law, nor an actual determination by the corporation

18.


(including its Board of Directors, independent legal counsel or its stockholders) that the claimant has not met such applicable standard of conduct, shall be a defense to the action or create a presumption that claimant has not met the applicable standard of conduct. In any suit brought by a director or executive officer to enforce a right to indemnification or to an advancement of expenses hereunder, the burden of proving that the director or executive officer is not entitled to be indemnified, or to such advancement of expenses, under this Article XI or otherwise shall be on the corporation.

(e) NON-EXCLUSIVITY OF RIGHTS. The rights conferred on any person by this Bylaw shall not be exclusive of any other right which such person may have or hereafter acquire under any statute, provision of the Certificate of Incorporation, Bylaws, agreement, vote of stockholders or disinterested directors or otherwise, both as to action in his official capacity and as to action in another capacity while holding office. The corporation is specifically authorized to enter into individual contracts with any or all of its directors, officers, employees or agents respecting indemnification and advances, to the fullest extent not prohibited by the Delaware General Corporation Law.

(f) SURVIVAL OF RIGHTS. The rights conferred on any person by this Bylaw shall continue as to a person who has ceased to be a director, officer, employee or other agent and shall inure to the benefit of the heirs, executors and administrators of such a person.

(g) INSURANCE. To the fullest extent permitted by the Delaware General Corporation Law, the corporation, upon approval by the Board of Directors, may purchase insurance on behalf of any person required or permitted to be indemnified pursuant to this Bylaw.

(h) AMENDMENTS. Any repeal or modification of this Bylaw shall only be prospective and shall not affect the rights under this Bylaw in effect at the time of the alleged occurrence of any action or omission to act that is the cause of any proceeding against any agent of the corporation.

(i) SAVING CLAUSE. If this Bylaw or any portion hereof shall be invalidated on any ground by any court of competent jurisdiction, then the corporation shall nevertheless indemnify each director and executive officer to the full extent not prohibited by any applicable portion of this Bylaw that shall not have been invalidated, or by any other applicable law.

(j) CERTAIN DEFINITIONS. For the purposes of this Bylaw, the following definitions shall apply:

(1) The term "proceeding" shall be broadly construed and shall include, without limitation, the investigation, preparation, prosecution, defense, settlement, arbitration and appeal of, and the giving of testimony in, any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative.

(2) The term "expenses" shall be broadly construed and shall include, without limitation, court costs, attorneys' fees, witness fees, fines, amounts paid in settlement or judgment and any other costs and expenses of any nature or kind incurred in connection with any proceeding.

19.


(3) The term the "corporation" shall include, in addition to the resulting corporation, any constituent corporation (including any constituent of a constituent) absorbed in a consolidation or merger which, if its separate existence had continued, would have had power and authority to indemnify its directors, officers, and employees or agents, so that any person who is or was a director, officer, employee or agent of such constituent corporation, or is or was serving at the request of such constituent corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, shall stand in the same position under the provisions of this Bylaw with respect to the resulting or surviving corporation as he would have with respect to such constituent corporation if its separate existence had continued.

(4) References to a "director," "executive officer," "officer," "employee," or "agent" of the corporation shall include, without limitation, situations where such person is serving at the request of the corporation as, respectively, a director, executive officer, officer, employee, trustee or agent of another corporation, partnership, joint venture, trust or other enterprise.

(5) References to "other enterprises" shall include employee benefit plans; references to "fines" shall include any excise taxes assessed on a person with respect to an employee benefit plan; and references to "serving at the request of the corporation" shall include any service as a director, officer, employee or agent of the corporation which imposes duties on, or involves services by, such director, officer, employee, or agent with respect to an employee benefit plan, its participants, or beneficiaries; and a person who acted in good faith and in a manner he reasonably believed to be in the interest of the participants and beneficiaries of an employee benefit plan shall be deemed to have acted in a manner "not opposed to the best interests of the corporation" as referred to in this Bylaw.

ARTICLE XII

NOTICES

SECTION 44. NOTICES.

(a) NOTICE TO STOCKHOLDERS. Whenever, under any provisions of these Bylaws, notice is required to be given to any stockholder, it shall be given in writing, timely and duly deposited in the United States mail, postage prepaid, and addressed to his last known post office address as shown by the stock record of the corporation or its transfer agent.

(b) NOTICE TO DIRECTORS. Any notice required to be given to any director may be given by the method stated in subsection (a), or by facsimile, telex or telegram, except that such notice other than one which is delivered personally shall be sent to such address as such director shall have filed in writing with the Secretary, or, in the absence of such filing, to the last known post office address of such director.

(c) AFFIDAVIT OF MAILING. An affidavit of mailing, executed by a duly authorized and competent employee of the corporation or its transfer agent appointed with respect to the class of stock affected, specifying the name and address or the names and addresses of the stockholder or stockholders, or director or directors, to whom any such notice or

20.


notices was or were given, and the time and method of giving the same, shall in the absence of fraud, be prima facie evidence of the facts therein contained.

(d) TIME NOTICES DEEMED GIVEN. All notices given by mail, as above provided, shall be deemed to have been given as at the time of mailing, and all notices given by facsimile, telex or telegram shall be deemed to have been given as of the sending time recorded at time of transmission.

(e) METHODS OF NOTICE. It shall not be necessary that the same method of giving notice be employed in respect of all directors, but one permissible method may be employed in respect of any one or more, and any other permissible method or methods may be employed in respect of any other or others.

(f) FAILURE TO RECEIVE NOTICE. The period or limitation of time within which any stockholder may exercise any option or right, or enjoy any privilege or benefit, or be required to act, or within which any director may exercise any power or right, or enjoy any privilege, pursuant to any notice sent him in the manner above provided, shall not be affected or extended in any manner by the failure of such stockholder or such director to receive such notice.

(g) NOTICE TO PERSON WITH WHOM COMMUNICATION IS UNLAWFUL. Whenever notice is required to be given, under any provision of law or of the Certificate of Incorporation or Bylaws of the corporation, to any person with whom communication is unlawful, the giving of such notice to such person shall not be required and there shall be no duty to apply to any governmental authority or agency for a license or permit to give such notice to such person. Any action or meeting which shall be taken or held without notice to any such person with whom communication is unlawful shall have the same force and effect as if such notice had been duly given. In the event that the action taken by the corporation is such as to require the filing of a certificate under any provision of the Delaware General Corporation Law, the certificate shall state, if such is the fact and if notice is required, that notice was given to all persons entitled to receive notice except such persons with whom communication is unlawful.

(h) NOTICE TO PERSON WITH UNDELIVERABLE ADDRESS. Whenever notice is required to be given, under any provision of law or the Certificate of Incorporation or Bylaws of the corporation, to any stockholder to whom (i) notice of two consecutive annual meetings, and all notices of meetings or of the taking of action by written consent without a meeting to such person during the period between such two consecutive annual meetings, or (ii) all, and at least two, payments (if sent by first class mail) of dividends or interest on securities during a twelve-month period, have been mailed addressed to such person at his address as shown on the records of the corporation and have been returned undeliverable, the giving of such notice to such person shall not be required. Any action or meeting which shall be taken or held without notice to such person shall have the same force and effect as if such notice had been duly given. If any such person shall deliver to the corporation a written notice setting forth his then current address, the requirement that notice be given to such person shall be reinstated. In the event that the action taken by the corporation is such as to require the filing of a certificate under any provision of the Delaware General Corporation Law, the certificate need not state that notice was not given to persons to whom notice was not required to be given pursuant to this paragraph.

RE: OPINION IN CONNECTION WITH FILING OF S-1 REGISTRATION STATEMENT

Ladies and Gentlemen:

You have requested our opinion with respect to certain matters in connection with the filing by Terayon Communication Systems, Inc. (the "Company") of a Registration Statement on Form S-1 (the "Registration Statement") with the Securities and Exchange Commission (the "Commission"), covering an underwritten public offering of up to 3,450,000 shares of Common Stock including 450,000 shares of Common Stock that may be sold pursuant to the exercise of an over- allotment option, (collectively, the "Common Stock").

In connection with this opinion, we have (i) examined and relied upon the Registration Statement and related Prospectus, the Company's Certificate of Incorporation and Bylaws, and the originals or copies certified to our satisfaction of such records, documents, certificates, memoranda and other instruments as in our judgment are necessary or appropriate to enable us to render the opinion expressed below, and (ii) that the shares of Common Stock will be sold by the underwriters at a price established by the Pricing Committee of the Board of Directors of the Company.

On the basis of the foregoing, and in reliance thereon, we are of the opinion that the Common Stock, when sold and issued in accordance with the Registration Statement and related Prospectus, will be validly issued, fully paid and nonassessable.

We consent to the reference to our firm under the caption "Legal Matters" in the Prospectus included on the Registration Statement and to the filing of this opinion as an exhibit to the Registration Statement.

Very truly yours,

COOLEY GODWARD LLP
