DESCRIPTION OF ARTWORK:

The gatefold includes a sample picture of the eBay homepage

The following text is contained on this gatefold:

[Two page screen shot of eBay home page with textual descriptions of eBay service attributes, surrounded by the following text flowed to both sides]

Welcome to the place where buyers and sellers deal with each other directly. This is eBay. It's an online auction community where over a million people visit every month. And they certainly seem to love their eBay (some have called it the thrill of the hunt)! In fact, this year alone, more than 500,000 new users have joined eBay--that's nearly 3,000 new community members just like you every day.

With a total of 846 categories, and about half a million items available on any given day, eBay is already the largest and most popular person-to-person trading community on the Internet--and there are an average of over 70,000 new items every day. All kinds of people are turning to eBay to find all kinds of stuff that was costly or difficult to find before.

Collectors and people with small businesses have often been able to expand in ways they'd never thought they could before coming to eBay (boundaries, geography, and distribution are kind of irrelevant on eBay).

It doesn't seem to matter whether they're buying, selling, devoted to a hobby or collection or even running a little business--a lot of people are talking about the kind of success they're finding on eBay.

When you buy or sell on eBay, you're dealing with another individual-- someone who knows exactly what they're selling or what they're looking for. Everyone is encouraged to (and most do) talk about what it's like to trade with someone. This feedback and rating system is an efficient way to check out the integrity of sellers and buyers. A positive eBay rating is worth its weight in gold...but beware...get too many negative ratings, and nobody in the community is going to do business with you (wouldn't it be nice if the rest of life was this clear cut?)

So whether you're looking for a rare 1922 Hamilton pocket watch or a retired Chilly the Polar Bear Beanie Baby(R), give it a try--and see if you'd like to make eBay your personal trading community--because even if you could find it somewhere else...what fun would that be?

THE COMPANY

eBay is the world's largest and most popular person-to-person trading community on the Internet. eBay pioneered online person-to-person trading by developing a Web-based community in which buyers and sellers are brought together in an efficient and entertaining auction format to buy and sell personal items such as antiques, coins, collectibles, computers, memorabilia, stamps and toys. The eBay service permits sellers to list items for sale, buyers to bid on items of interest and all eBay users to browse through listed items in a fully-automated, topically-arranged, intuitive and easy-to-use online service that is available 24 hours a day, seven days a week. From inception through June 30, 1998, eBay hosted over 15 million auctions resulting in gross merchandise sales in excess of $340 million. During the first half of 1998, the number of registered eBay users grew from approximately 340,000 to over 850,000 and the number of simultaneous auctions being conducted through eBay increased from approximately 200,000 to over 500,000. The Company believes that this critical mass of buyers, sellers and items listed for sale creates a cycle that helps eBay continue to grow its user base. Sellers are attracted to eBay as a result of the large number of potential buyers, and buyers in turn are attracted to eBay by the broad selection of goods listed on eBay. eBay provides buyers and sellers a place to socialize, to discuss topics of common interest and, ultimately, to conduct business in a compelling trading environment, thus fostering a large and growing commerce-oriented online community.

The Internet offers for the first time the opportunity to create a compelling global marketplace for person-to-person trading--the exchange of goods between individuals. This trading has traditionally been conducted through trading forums, such as classified advertisements, collectibles shows, garage sales and flea markets, or through intermediaries, such as auction houses and local dealer shops. These markets are highly inefficient because: (i) their fragmented, regional nature makes it difficult and expensive for buyers and sellers to meet, exchange information and complete transactions; (ii) they offer a limited variety and breadth of goods; (iii) they often have high transaction costs from intermediaries; and (iv) they are information inefficient, as buyers and sellers lack a reliable and convenient means of setting prices for sales or purchases. Despite these inefficiencies, the Company believes that the market for traditional person-to-person trading in the U.S. through auctions and classified ads exceeded $50 billion in goods sold in 1997. An Internet-based centralized trading place can overcome the inefficiencies associated with traditional person-to-person trading by facilitating buyers and sellers meeting, listing items for sale, exchanging information, interacting with each other and, ultimately, consummating transactions. Through such a trading place, buyers can access a significantly broader selection of goods to purchase and sellers have the opportunity to sell their goods efficiently to a broader base of buyers. As a result, a significant market opportunity exists for an Internet-based centralized trading place that applies the unique attributes of the Internet to facilitate person-to-person trading.

3

eBay offers Web users the opportunity to join the world's largest Internet- based, person-to-person trading community. Any visitor to eBay can browse among over 500,000 items for sale, many of which are unique or otherwise hard to find, organized across 846 product categories, facilitating easy exploration. Browsers and buyers can also search auction listings for specific items or search by category, keyword, seller name, recently-commenced auctions or auctions about to end. eBay's auction format fosters a sense of urgency among buyers to bid for goods and creates an entertaining and compelling trading environment. Within minutes of registering as an eBay user, a seller can immediately list an item for sale, identify a minimum price for opening bids and specify how long the auction will last. Sellers pay a nominal placement fee for an item based on the seller's minimum price for the item, ranging from $0.25 to $2.00, and can highlight their auction for additional fees, ranging from $2.00 to $49.95. At the end of the auction period, if a bid exceeds the seller's minimum price, eBay automatically notifies the buyer and seller via email and then the buyer and seller consummate the transaction independently of eBay. At the time of notification, eBay charges the seller a success fee that steps down from 5% to 1.25% based on the closing price of the item. Buyers are not charged for making bids or purchases through eBay. At no point during the process does the Company take possession of either the item being sold or the buyer's payment for the item. Following completion of a transaction, each user is encouraged to submit compliments or criticism to the trading profile of his or her trading partner on eBay's "Feedback Forum." This Feedback Forum, which was pioneered by eBay, is intended to reduce the anonymity and uncertainty of dealing with an unknown trading partner and to help overcome initial user hesitancy when trading over the Web. eBay's Feedback Forum and comprehensive community services, such as chat rooms, bulletin boards and email, are designed to foster safe, direct interaction between buyers and sellers with similar interests, thus promoting a sense of community among users and encouraging consumer loyalty and repeat usage. These benefits have contributed to the successful completion of well over 50% of all auctions listed on eBay since inception.

eBay's objective is to enhance its position as the world's leading online person-to-person trading community. Key elements of the Company's strategy include: (i) growing the eBay community and eBay brand, both to attract new members and to maintain the vitality of the eBay community; (ii) broadening eBay's trading platform by growing existing product categories, promoting new product categories and expanding internationally; (iii) fostering eBay community affinity; (iv) enhancing eBay site features and functionality through the introduction of personalization features, new auction formats and category- specific content; (v) introducing pre- and post-trade value-added services, such as shipping and third-party escrow services; and (vi) leveraging its unique business model, which does not require it to carry inventory or maintain a sales force, to grow its business.

The Company was formed as a sole proprietorship in September 1995, incorporated in California in May 1996 and reincorporated in Delaware in April 1998. The Company's principal executive offices are located at 2005 Hamilton Avenue, Suite 350, San Jose, California 95125. The Company's telephone number is (408) 369-4830 and its Web site is located at www.ebay.com. Information contained on the Company's Web site shall not constitute a part of this Prospectus.

EBAY FOUNDATION

In June 1998, the Company established a charitable fund known as the eBay Foundation, which is administered by the Community Foundation Silicon Valley. To capitalize this foundation, eBay donated 107,250 shares of Common Stock to the Community Foundation Silicon Valley on behalf of the eBay Foundation. The Community Foundation Silicon Valley is selling 10,725 shares of Common Stock in this offering on behalf of the eBay Foundation. Through the Community Foundation Silicon Valley, the eBay Foundation will make grants to charitable organizations. The Company intends to involve the members of the eBay community in determining the charitable purposes to which proceeds from the sale of these shares will be devoted.

RISK FACTORS

This offering involves a high degree of risk. In addition to the other information set forth in this Prospectus, the following risk factors should be considered carefully in evaluating the Company and its business before purchasing any of the shares of Common Stock of the Company. This Prospectus contains certain forward-looking statements that involve risks and uncertainties, such as statements of the Company's plans, objectives, expectations and intentions. When used in this Prospectus, the words "expects," "anticipates," "intends" and "plans" and similar expressions are intended to identify certain of these forward-looking statements. 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 in this Prospectus. Factors that could cause or contribute to such differences include those discussed below, as well as those discussed elsewhere in this Prospectus.

LIMITED OPERATING HISTORY; NO ASSURANCE OF CONTINUED PROFITABILITY

The Company was formed as a sole proprietorship in September 1995 and incorporated in May 1996. Thus, it has only a limited operating history on which to base an evaluation of its business and prospects. The Company's prospects must be considered in light of the risks, uncertainties, expenses and difficulties frequently encountered by companies in their early stages of development, particularly companies in new and rapidly evolving markets such as online commerce. To address these risks and uncertainties, the Company must, among other things, maintain and increase the number of its registered users, items listed on its service, completed auctions, maintain and enhance its brand, implement and execute its business and marketing strategy successfully, continue to develop and upgrade its technology and information- processing systems, continue to enhance the eBay service to meet the needs of a changing market, provide superior customer service, respond to competitive developments and attract, integrate, retain and motivate qualified personnel. There can be no assurance that the Company will be successful in accomplishing all of these things, and the failure to do so could have a material adverse effect on the Company's business, results of operations and financial condition.

The Company believes that its continued growth and profitability will depend in large part on its ability to (i) increase its brand name awareness, (ii) provide its customers with superior community and trading experiences and
(iii) maintain sufficient transaction volume to attract buyers and sellers. Accordingly, the Company intends to invest heavily in marketing and promotion, site development, technology and operating infrastructure development. Although the Company has experienced significant revenue growth and significant growth in the number of its registered users and items listed for auction by its users in recent periods, such growth rates are not sustainable and will decrease in the future. In view of the rapidly evolving nature of the Company's business and its limited operating history, the Company believes that period-to-period comparisons of its operating results are not necessarily meaningful and should not be relied upon as indications of future performance. See "Management's Discussion and Analysis of Financial Condition and Results of Operations."

POTENTIAL FLUCTUATIONS IN RESULTS OF OPERATIONS; SEASONALITY

The Company's operating results have varied on a quarterly basis during its short operating history and may fluctuate significantly as a result of a variety of factors, many of which are outside the Company's control. Factors that may affect the Company's quarterly operating results include: (i) the Company's ability to retain an active user base, attract new users who list items for sale and who complete transactions through its service and maintain customer satisfaction; (ii) the Company's ability to manage the number of items listed on its service; (iii) the announcement or introduction of new sites, services and products by the Company or its competitors; (iv) the success of the Company's brand building and marketing campaigns; (v) price competition; (vi) the level of use of the Internet and online

6

services; (vii) increasing consumer confidence in and acceptance of the Internet and other online services for commerce and, in particular, the trading of products such as those listed on eBay; (viii) consumer confidence in the security of transactions over the Internet; (ix) the Company's ability to upgrade and develop its systems and infrastructure to accommodate growth; (x) the Company's ability to attract new personnel in a timely and effective manner; (xi) the volume of items listed on the Company's Web site; (xii) the timing, cost and availability of advertising in traditional media and on other Web sites and online services; (xiii) technical difficulties or service interruptions; (xiv) the amount and timing of operating costs and capital expenditures relating to expansion of the Company's business, operations and infrastructure; (xv) consumer trends and popularity of certain categories of collectible items; (xvi) volume, size, timing and completion rate of trades on eBay; (xvii) governmental regulation by Federal or local governments; and
(xviii) general economic conditions as well as economic conditions specific to the Internet and online commerce industries.

As a result of the Company's limited operating history and the emerging nature of the markets in which it competes, it is difficult for the Company to forecast its revenues or earnings accurately. In addition, the Company has no backlog and a significant portion of the Company's net revenues for a particular quarter are derived from auctions that are listed and completed during that quarter. The Company's current and future expense levels are based largely on its investment plans and estimates of future revenues and are, to a large extent, fixed. The Company may be unable to adjust spending in a timely manner to compensate for any unexpected revenue shortfall. Accordingly, any significant shortfall in revenues relative to the Company's planned expenditures would have an immediate adverse effect on the Company's business, results of operations and financial condition. Further, as a strategic response to changes in the competitive environment, the Company may from time to time make certain pricing, service or marketing decisions that could have a material adverse effect on its business, results of operations and financial condition.

The Company believes that its results of operations are somewhat seasonal in nature, with fewer auctions listed around the Thanksgiving and Christmas holidays in the fourth quarter. The Company's limited operating history, however, makes it difficult to fully assess the impact of these seasonal factors or whether or not its business is susceptible to cyclical fluctuations in the U.S. economy. In addition, the Company believes that its rapid growth may have overshadowed whatever seasonal or cyclical factors might have influenced its business to date. There can be no assurance that seasonal or cyclical variations in the Company's operations will not become more pronounced over time or that they will not materially adversely affect its results of operations in the future. Moreover, consumer "fads" and other changes in consumer trends may cause significant fluctuations in the Company's operating results from one quarter to the next. See "--Risks Related to Consumer Trends."

Due to the foregoing factors, the Company's quarterly revenues and operating results are difficult to forecast. The Company believes that period-to-period comparisons of its operating results may not be meaningful and should not be relied upon as an indication of future performance. In addition, it is likely that in one or more future quarters the Company's operating results will fall below the expectations of securities analysts and investors. In such event, the trading price of the Common Stock would almost certainly be materially adversely affected. See "Management's Discussion and Analysis of Financial Condition and Results of Operations."

MANAGEMENT OF POTENTIAL GROWTH; NEW MANAGEMENT TEAM; DEPENDENCE ON KEY PERSONNEL

The Company is currently experiencing a period of significant expansion and anticipates that further expansion will be required to address potential growth in its customer base and market opportunities. This expansion has placed, and is expected to continue to place, a significant strain on the Company's management, operational and financial resources. From inception to June 30, 1998, the Company expanded from one to 76 employees. Certain members of the Company's management, including the Company's President and Chief Executive Officer, have joined the Company within the

7

last year. The Company's new employees include a number of key managerial, marketing, planning, technical and operations personnel who have not yet been fully integrated into the Company, and the Company expects to add additional key personnel in the near future. To manage the expected growth of its operations and personnel, the Company will be required to improve existing and implement new transaction processing, operational and financial systems, procedures and controls, and to expand, train and manage its growing employee base. The Company also will be required to expand its finance, administrative and operations staff. Further, the Company may be required to enter into relationships with various strategic partners, Web sites and other online service providers and other third parties necessary to the Company's business. There can be no assurance that the Company's current and planned personnel, systems, procedures and controls will be adequate to support the Company's future operations, that management will be able to hire, train, retain, motivate and manage required personnel or that Company management will be able to identify, manage and exploit existing and potential strategic relationships and market opportunities. The failure of the Company to manage growth effectively could have a material adverse effect on the Company's business, results of operations and financial condition. See "Management's Discussion and Analysis of Financial Condition and Results of Operations" and "Business-- Employees."

The Company's performance is substantially dependent on the continued services and on the performance of its senior management and other key personnel. The Company's performance also depends on the Company's ability to retain and motivate its other officers and key employees. The loss of the services of any of its executive officers or other key employees could have a material adverse effect on the Company's business, results of operations and financial condition. The Company does not have long-term employment agreements with any of its key personnel and maintains no "key person" life insurance policies. The Company's future success also depends on its ability to identify, attract, hire, train, retain and motivate other highly skilled technical, managerial, marketing and customer service personnel. Competition for such personnel is intense, and there can be no assurance that the Company will be able to successfully attract, integrate or retain sufficiently qualified personnel. In particular, the Company has encountered difficulties in attracting a sufficient number of qualified software developers for its Web site and transaction processing systems, and there can be no assurance that the Company will be able to retain and attract such developers. The failure to retain and attract the necessary personnel could have a material adverse effect on the Company's business, results of operations and financial condition. See "Business--Employees" and "Management."

DEVELOPING MARKET; DEPENDENCE ON CONTINUED GROWTH OF ONLINE PERSON-TO-PERSON COMMERCE

The market for the sale of goods over the Internet, particularly through person-to-person trading, is a new and emerging market. The Company's future revenues and profits are substantially dependent upon the widespread acceptance and use of the Internet and other online services as a medium for commerce by consumers. Rapid growth in the use of and interest in the Web, the Internet and other online services is a recent phenomenon and there can be no assurance that this acceptance and use will continue to develop or that a sufficiently broad base of consumers will adopt, and continue to use, the Internet as a medium of commerce. Demand and market acceptance for recently introduced services and products over the Internet are subject to a high level of uncertainty, and there exist few proven services and products. Growth in the Company's user base relies on obtaining consumers who have historically used traditional means of commerce to purchase goods. For the Company to be successful, these consumers must accept and use novel ways of conducting business and exchanging information.

In addition, the Internet may not be commercially viable in the long term for a number of reasons, including potentially inadequate development of the necessary network infrastructure or delayed development of enabling technologies, performance improvements and security measures. To the extent that the Internet continues to experience significant growth in the number of users, their frequency of use or their bandwidth requirements, there can be no assurance that the infrastructure

8

for the Internet and other online services will be able to support the demands placed upon them. In addition, the Internet or other online services could lose their viability due to delays in the development or adoption of new standards and protocols required to handle increased levels of Internet or other online service activity, or due to increased governmental regulation. Changes in or insufficient availability of telecommunications services to support the Internet or other online services also could result in slower response times and adversely affect usage of the Internet and other online services generally and the eBay service in particular. If use of the Internet and other online services does not continue to grow or grows more slowly than expected, if the infrastructure for the Internet and other online services does not effectively support growth that may occur, or if the Internet and other online services do not become a viable commercial marketplace, the Company's business, results of operations and financial condition would be materially adversely affected.

RISK OF CAPACITY CONSTRAINTS

The Company seeks to generate a high volume of traffic and transactions on the eBay service. Accordingly, the satisfactory performance, reliability and availability of the Company's Web site, processing systems and network infrastructure are critical to the Company's reputation and its ability to attract and retain large numbers of users who bid for or sell items on its service while maintaining adequate customer service levels. The Company's revenues depend on the number of items listed by users, the volume of user auctions that are successfully completed and the final prices paid for the items listed. Any system interruptions that result in the unavailability of the Company's service or reduced customer activity would reduce the volume of items listed and auctions completed and could affect the average selling price of the items. Interruptions of service may also diminish the attractiveness of the Company and its services. The Company has experienced periodic system interruptions, which it believes will continue to occur from time to time. Any substantial increase in the volume of traffic on the Company's Web site or in the number of auctions being conducted by customers will require the Company to expand and upgrade its technology, transaction processing systems and network infrastructure. There can be no assurance that the Company will be able to accurately project the rate or timing of increases, if any, in the use of the eBay service or timely expand and upgrade its systems and infrastructure to accommodate such increases in a timely manner. Any failure to expand or upgrade its systems could have a material adverse effect on the Company's business, results of operations and financial condition.

The Company uses internally developed systems for its service and transaction processing, including billing and collections processing. The Company must continually enhance and improve these systems in order to accommodate the level of use of eBay. Furthermore, in the future, the Company may add additional features and functionality to its services that would result in the need to develop or license additional technologies. The Company's inability to add additional software and hardware or to develop and further upgrade its existing technology, transaction processing systems or network infrastructure to accommodate increased traffic on the eBay service or increased transaction volume through its processing systems or to provide new features or functionality may cause unanticipated system disruptions, slower response times, degradation in levels of customer service, impaired quality of the user's experience on the eBay service, and delays in reporting accurate financial information. In addition, although the Company works to prevent unauthorized access to Company data, it is impossible to completely eliminate this risk. There can be no assurance that the Company will be able in a timely manner to effectively upgrade and expand its systems or to integrate smoothly any newly developed or purchased technologies with its existing systems. Any inability to do so would have a material adverse effect on the Company's business, results of operations and financial condition. See "--Risk of System Failures" and "Business--Operations and Technology."

RISK OF SYSTEM FAILURES

The Company's success, and in particular its ability to facilitate trades successfully and provide high quality customer service, depends on the efficient and uninterrupted operation of its computer and communications hardware systems. Substantially all of the Company's computer hardware for operating the eBay service is currently located at the facilities of Exodus Communications, Inc. ("Exodus") in Santa Clara, California. These systems and operations are vulnerable to damage or interruption from earthquakes, floods, fires, power loss, telecommunication failures, break-ins, sabotage, intentional acts of vandalism and similar events. The Company does not presently have fully redundant systems, a formal disaster recovery plan or alternative providers of hosting services and does not carry sufficient business interruption insurance to compensate it for losses that may occur. Despite any precautions taken by, and planned to be taken by the Company, the occurrence of a natural disaster or other unanticipated problems at the Exodus facility could result in interruptions in the services provided by the Company. In addition, the failure by Exodus to provide the data communications capacity required by the Company, as a result of human error, natural disaster or other operational disruption, could result in interruptions in the Company's service. Any damage to or failure of the systems of the Company could result in reductions in, or terminations of, the eBay service, which could have a material adverse effect on the Company's business, results of operations and financial condition.

In the case of frequent or persistent system failures, the Company's reputation and name brand could be materially adversely affected. Although the Company has implemented certain network security measures, its servers are also vulnerable to computer viruses, physical or electronic break-ins and similar disruptions, which could lead to interruptions, delays, loss of data or the inability to complete customer auctions, any and all of which could have a material adverse effect on the Company's business, results of operations and financial condition. See "Business--Operations and Technology" and "-- Facilities. "

INTENSE COMPETITION

The market for person-to-person trading over the Internet is new, rapidly evolving and intensely competitive, and the Company expects competition to intensify further in the future. Barriers to entry are relatively low, and current and new competitors can launch new sites at a relatively low cost using commercially-available software. The Company currently or potentially competes with a number of other companies. The Company's direct competitors include various online person-to-person auction services, including Onsale Exchange, a division of Onsale, Inc. ("Onsale"); Auction Universe, a Times-Mirror Company; Excite, Inc. ("Excite"); and a number of other small services, including those that serve specialty markets. The Company also competes indirectly with business-to-consumer online auction services such as Onsale, First Auction, ZAuction and Surplus Auction. The Company potentially faces competition from a number of large online communities and services that have expertise in developing online commerce and in facilitating online person-to-person interaction. Certain of these potential competitors, including Amazon.com, America Online, Inc. ("AOL"), Microsoft Corporation ("Microsoft") and Yahoo! Inc. ("Yahoo!"), currently offer a variety of business-to-consumer trading services and classified ad services and certain of these companies may introduce person-to-person trading to their large user populations. Other large companies with strong brand recognition and experience in online commerce, such as Cendant Corporation, QVC and large newspaper or media companies may also seek to compete in the online auction market. Competitive pressures created by any one of these companies, or by the Company's competitors collectively, could have a material adverse effect on the Company's business, results of operations and financial condition.

The Company believes that the principal competitive factors in its market are volume and selection of goods, population of buyers and sellers, community cohesion and interaction, customer service, reliability of delivery and payment by users, brand recognition, Web site convenience and accessibility,

10

price, quality of search tools and system reliability. Many of the Company's current and potential competitors have longer operating histories, larger customer bases, greater brand recognition and significantly greater financial, marketing, technical and other resources than the Company. In addition, other online trading services may be acquired by, receive investments from or enter into other commercial relationships with larger, well-established and well- financed companies as use of the Internet and other online services increases. Therefore, certain of the Company's competitors with other revenue sources may be able to devote greater resources to marketing and promotional campaigns, adopt more aggressive pricing policies and devote substantially more resources to Web site and systems development than the Company or may try to attract traffic by offering services for free. Increased competition may result in reduced operating margins, loss of market share and diminished value in the Company's brand. There can be no assurance that the Company will be able to compete successfully against current and future competitors. Further, as a strategic response to changes in the competitive environment, the Company may, from time to time, make certain pricing, service or marketing decisions or acquisitions that could have a material adverse effect on its business, results of operations and financial condition. New technologies and the expansion of existing technologies may increase the competitive pressures on the Company by enabling the Company's competitors to offer a lower-cost service. Certain Web- based applications that direct Internet traffic to certain Web sites may channel users to trading services that compete with the Company. Although the Company has established Internet traffic arrangements with several large online services and search engine companies, there can be no assurance that these arrangements will be renewed on commercially reasonable terms or that they will otherwise continue to result in increased usage of the eBay service. In addition, companies that control access to transactions through network access or Web browsers could promote the Company's competitors or charge the Company substantial fees for inclusion. Any and all of these events could have a material adverse effect on the Company's business, results of operations and financial condition. See "Business--Competition."

RISKS ASSOCIATED WITH BRAND DEVELOPMENT

The Company believes that its historical growth has been largely attributable to word-of-mouth. Despite this historical organic growth, the Company believes that continuing to strengthen its brand is critical to achieving widespread acceptance of eBay, particularly in light of the competitive nature of the Company's market. Promoting and positioning its brand will depend largely on the success of the Company's marketing efforts and the ability of the Company to provide high quality services. In order to promote its brand, the Company will need to increase its marketing budget and otherwise increase its financial commitment to creating and maintaining brand loyalty among users. There can be no assurance that brand promotion activities will yield increased revenues or that any such revenues would offset the expenses incurred by the Company in building its brand. Further, there can be no assurance that any new users attracted to eBay will conduct transactions over eBay on a regular basis. If the Company fails to promote and maintain its brand or incurs substantial expenses in an attempt to promote and maintain its brand or if the Company's existing or future strategic relationships fail to promote the Company's brand or increase brand awareness, the Company's business, results of operations and financial condition would be materially adversely affected. See "Business--eBay Strategy."

RAPID TECHNOLOGICAL CHANGE; RISKS ASSOCIATED WITH NEW SERVICES, FEATURES AND FUNCTIONS

The market in which the Company competes is characterized by rapidly changing technology, evolving industry standards, frequent new service and product announcements, introductions and enhancements and changing customer demands. These market characteristics are exacerbated by the emerging nature of the Web and the apparent need of companies from a multitude of industries to offer Web- based products and services. Accordingly, the Company's future success will depend on its ability to adapt to rapidly changing technologies, to adapt its services to evolving industry standards and to continually improve the performance, features and reliability of its service in response to competitive

11

service and product offerings and evolving demands of the marketplace. The failure of the Company to adapt to such changes would have a material adverse effect on the Company's business, results of operations and financial condition. In addition, the widespread adoption of new Internet, networking or telecommunications technologies or other technological changes could require substantial expenditures by the Company to modify or adapt its services or infrastructure, which could have a material adverse effect on the Company's business, results of operations and financial condition. See "Business-- Operations and Technology."

The Company plans to expand its operations by developing and promoting new or complementary services, products or transaction formats or expanding the breadth and depth of services. There can be no assurance that the Company would be able to expand its operations in a cost-effective or timely manner or that any such efforts would maintain or increase overall market acceptance. Furthermore, any new business or service launched by the Company that is not favorably received by consumers could damage the Company's reputation and diminish the value of its brand name. Expansion of the Company's operations in this manner would also require significant additional expenses and development, operations and other resources and would strain the Company's management, financial and operational resources. The lack of market acceptance of such services or the Company's inability to generate satisfactory revenues from such expanded services to offset their cost could have a material adverse effect on the Company's business, results of operations and financial condition.

RISKS RELATED TO CONSUMER TRENDS

The Company derives substantially all of its revenues from fees from sellers for listing products for sale on its service and fees from successfully completed auctions. The Company's future revenues will depend upon continued demand for the types of goods that are listed by users of the eBay service. The popularity of certain categories of items, such as toys, dolls and memorabilia, among consumers may vary over time due to perceived scarcity, subjective value, and societal and consumer trends in general. For example during the three months ended June 30, 1998, the Company had, at times, over 30,000 simultaneous auctions listed in its "Beanie Babies" category. A decline in the popularity of, or demand for, certain collectibles or other items sold through the eBay service could reduce the overall volume of transactions on the eBay service, resulting in reduced revenues. In addition, certain consumer "fads" may temporarily inflate the volume of certain types of items listed on the eBay service, placing a significant strain upon the Company's infrastructure and transaction capacity. These trends may also cause significant fluctuations in the Company's operating results from one quarter to the next. Any decline in demand for the goods offered through the eBay service as a result of changes in consumer trends could have a material adverse effect on the Company's business, results of operations and financial condition.

RISKS ASSOCIATED WITH CERTAIN ACTIVITIES ON THE COMPANY'S SERVICE

The law relating to the liability of providers of online services for activities of their users on the service is currently unsettled. While the Company does not pre-screen the types of goods offered on eBay, the Company is aware that certain goods, such as alcohol, tobacco, firearms, adult material and other goods that may be subject to regulation by local, state or federal authorities have been traded on the eBay service. There can be no assurance that the Company will be able to prevent the unlawful exchange of goods on its service or that it will successfully avoid civil or criminal liability for unlawful activities carried out by users through the Company's service. The imposition upon the Company of potential liability for unlawful activities of users of the eBay service could require the Company to implement measures to reduce its exposure to such liability, which may require, among other things, the Company to spend substantial resources and/or or to discontinue certain service offerings. Any costs incurred as a result of such liability or asserted liability could have a material adverse effect on the Company's business, results of operations and financial condition. See "Business--Government Regulation."

12

In addition, the Company's success depends largely upon sellers reliably delivering and accurately representing the listed goods and buyers paying the agreed purchase price. The Company takes no responsibility for delivery of payment or goods to any user of the eBay service. The Company has received in the past, and anticipates that it will receive in the future, communications from users who did not receive the purchase price or the goods that were to have been exchanged. While the Company can suspend the accounts of users who fail to fulfill their delivery obligations to other users, the Company, beyond crediting sellers with the amount of their fees in certain circumstances, does not have the ability to otherwise require users to make payments or deliver goods and the Company does not compensate users who believe they have been defrauded by other users. The Company also from time to time receives complaints from buyers as to the quality of the goods purchased. Although the Company has attempted to reduce its liability to buyers for unfulfilled transactions or other claims related to the quality of the purchased goods and although the average transaction size is approximately $40.00, the Company may in the future receive additional requests from users requesting reimbursement or threatening legal action against the Company if no reimbursement is made. Any resulting litigation could be costly for the Company, divert management attention and could result in increased costs of doing business, or otherwise have a material adverse effect on the Company's business, results of operations and financial condition. Any negative publicity generated as a result of fraudulent or deceptive conduct by users of eBay could damage the Company's reputation and diminish the value of its brand name, which could have a material adverse effect on the Company's business, results of operations and financial condition.

The Company does not pre-screen the goods that are listed by users on eBay or the contents of their listings, which may include text and images. The Company has received in the past, and anticipates that it will receive in the future, communications alleging that certain items sold through the eBay service infringe third-party copyrights, trademarks or other intellectual property rights. While the Company's user policy prohibits the sale of goods which may infringe third-party intellectual property rights and the Company is empowered to suspend the account of any user who infringes third-party intellectual property rights, there can be no assurance that an allegation of infringement will not result in litigation against the Company. Any such litigation could be costly for the Company and could result in increased costs of doing business, or could in some other manner have a material adverse effect on the Company's business, results of operations and financial condition. See "Business--The eBay Service."

ONLINE COMMERCE SECURITY RISKS

A significant barrier to online commerce and communications is the secure transmission of confidential information over public networks. Currently, a significant number of eBay users authorize the Company to bill their credit card accounts directly for all transaction fees charged by the Company. The Company relies on encryption and authentication technology licensed from third parties to provide the security and authentication technology to effect secure transmission of confidential information, including customer credit card numbers. There can be no assurance that advances in computer capabilities, new discoveries in the field of cryptography, or other events or developments will not result in a compromise or breach of the technology used by the Company to protect customer transaction data. If any such compromise of the Company's security were to occur, it could have a material adverse effect on the Company's reputation and, therefore, on its business, results of operations and financial condition. Furthermore, a party who is able to circumvent the Company's security measures could misappropriate proprietary information or cause interruptions in the Company's operations. The Company may be required to expend significant capital and other resources to protect against such security breaches or to alleviate problems caused by such breaches. Concerns over the security of transactions conducted on the Internet and other online services and the privacy of users may also inhibit the growth of the Internet and other online services generally, and the Web in particular, especially as a means of conducting commercial transactions. To the extent that activities of the Company involve the storage and transmission of proprietary information, such as credit card numbers,

13

security breaches could damage the Company's reputation and expose the Company to a risk of loss or litigation and possible liability. The Company's insurance policies carry low coverage limits, which may not be adequate to reimburse the Company for losses caused by security breaches. There can be no assurance that the Company's security measures will prevent security breaches or that failure to prevent such security breaches will not have a material adverse effect on the Company's business, results of operations and financial condition. See "Business--Operations and Technology."

RISKS ASSOCIATED WITH ACQUISITIONS

If appropriate opportunities present themselves, the Company intends to acquire businesses, technologies, services or products that the Company believes are strategic. For example, the Company recently acquired Jump Incorporated ("Jump") the developer and operator of Up4Sale, an advertising- supported online trading service for an aggregate transaction value of $2.3 million. The Company currently has no understandings, commitments or agreements with respect to any other material acquisition and no other material acquisition is currently being pursued. There can be no assurance that the Company will be able to identify, negotiate or finance future acquisitions successfully, or to integrate such acquisitions with its current business. The process of integrating an acquired business, technology, service or product into the Company may result in unforeseen operating difficulties and expenditures and may absorb significant management attention that would otherwise be available for ongoing development of the Company's business. Moreover, there can be no assurance that the anticipated benefits of any acquisition, including Jump, will be realized. Future acquisitions could result in potentially dilutive issuances of equity securities, the incurrence of debt, contingent liabilities and/or amortization expenses related to goodwill and other intangible assets, which could materially adversely affect the Company's business, results of operations and financial condition. Any such future acquisitions of other businesses, technologies, services or products might require the Company to obtain additional equity or debt financing, which might not be available on terms favorable to the Company, or at all, and such financing, if available, might be dilutive. See "Management's Discussion and Analysis of Financial Condition and Results of Operations" and "Business-- Acquisition of Jump."

DEPENDENCE ON THE WEB INFRASTRUCTURE

The success of the eBay service will depend in large part upon the development and maintenance of the Web infrastructure, such as a reliable network backbone with the necessary speed, data capacity and security, or timely development of complementary products such as high speed modems, for providing reliable Web access and services. Because global commerce and the online exchange of information is new and evolving, it is difficult to predict with any assurance whether the Web will prove to be a viable commercial marketplace in the long term. The Web has experienced, and is expected to continue to experience, significant growth in the numbers of users and amount of traffic. To the extent that the Web continues to experience increased numbers of users, frequency of use or increased bandwidth requirements of users, there can be no assurance that the Web infrastructure will continue to be able to support the demands placed on it by this continued growth or that the performance or reliability of the Web will not be adversely affected. Furthermore, the Web has experienced a variety of outages and other delays as a result of damage to portions of its infrastructure, and could face such outages and delays in the future, including outages and delays resulting from the inability of certain computers or software to distinguish dates in the 21st century from dates in the 20th century. See "--Year 2000 Implications." These outages and delays could adversely affect the level of Web usage and also the level of traffic and the processing of auctions on eBay. In addition, the Web could lose its viability due to delays in the development or adoption of new standards and protocols to handle increased levels of activity or due to increased governmental regulation. There can be no assurance that the infrastructure or complementary products or services necessary to make the Web a viable commercial marketplace for the long term will be developed or that if they are developed, that the Web will become a viable commercial marketplace for services such as those

14

offered by the Company. If the necessary infrastructure, standard or protocols or complementary products, services or facilities are not developed, or if the Web does not become a viable commercial marketplace, the Company's business, results of operations and financial condition will be materially and adversely affected. Even if the infrastructure, standards or protocols or complementary products, services or facilities are developed and the Web becomes a viable commercial marketplace in the long term, the Company might be required to incur substantial expenditures in order to adapt its service to changing Web technologies, which could have a material adverse effect on the Company's business, results of operations and financial condition. See "Business-- Industry Background."

RISKS ASSOCIATED WITH INFORMATION DISSEMINATED THROUGH THE COMPANY'S SERVICE

The law relating to the liability of online services companies for information carried on or disseminated through their services is currently unsettled. It is possible that claims could be made against online services companies under both United States and foreign law for defamation, libel, invasion of privacy, negligence, copyright or trademark infringement, or other theories based on the nature and content of the materials disseminated through their services. Several private lawsuits seeking to impose such liability upon other online services companies are currently pending. In addition, legislation has been proposed that imposes liability for or prohibits the transmission over the Internet of certain types of information. The eBay service features a Feedback Forum, which includes information from users regarding the reliability of other users in promptly paying or delivering goods sold in an auction transaction. Although all such feedback is generated by users and not by the Company, it is possible that a claim of defamation or other injury could be made against the Company for content posted in the Feedback Forum. The imposition upon the Company and other online services providers of potential liability for information carried on or disseminated through their services could require the Company to implement measures to reduce its exposure to such liability, which may require the Company to expend substantial resources and/or to discontinue certain service offerings. In addition, the increased attention focused upon liability issues as a result of these lawsuits and legislative proposals could impact the growth of Internet use. While the Company carries liability insurance, it may not be adequate to fully compensate the Company in the event the Company becomes liable for information carried on or disseminated through its service. Any costs not covered by insurance incurred as a result of such liability or asserted liability could have a material adverse effect on the Company's business, results of operations and financial condition. See "Business--Government Regulation" and "--Privacy Policy."

GOVERNMENTAL REGULATION AND LEGAL UNCERTAINTIES

The Company is not currently subject to direct federal, state or local regulation, and laws or regulations applicable to access to or commerce on the Internet, other than regulations applicable to businesses generally. However, due to the increasing popularity and use of the Internet and other online services, it is possible that a number of laws and regulations may be adopted with respect to the Internet or other online services covering issues such as user privacy, freedom of expression, pricing, content and quality of products and services, taxation, advertising, intellectual property rights and information security. Although sections of the Communications Decency Act of 1996 (the "CDA") that, among other things, proposed to impose criminal penalties on anyone distributing "indecent" material to minors over the Internet, were held to be unconstitutional by the U.S. Supreme Court, there can be no assurance that similar laws will not be proposed and adopted. Certain members of Congress have recently discussed proposing legislation that would regulate the distribution of "indecent" material over the Internet in a manner that they believe would withstand challenge on constitutional grounds. The nature of such similar legislation and the manner in which it may be interpreted and enforced cannot be fully determined and, therefore, legislation similar to the CDA could subject the Company and/or its customers to potential liability, which in turn could have an adverse effect on the Company's business, results of operations and financial condition. The adoption of any such laws or regulations might also decrease the rate of growth of Internet use, which in turn could decrease the demand for

15

the eBay service or increase the cost of doing business or in some other manner have a material adverse effect on the Company's business, results of operations and financial condition. In addition, applicability to the Internet of existing laws governing issues such as property ownership, copyrights and other intellectual property issues, taxation, libel, obscenity and personal privacy is uncertain. The vast majority of such laws were adopted prior to the advent of the Internet and related technologies and, as a result, do not contemplate or address the unique issues of the Internet and related technologies. In addition, numerous states, including the State of California in which the Company's headquarters are located, have regulations regarding the manner in which "auctions" may be conducted and the liability of "auctioneers" in conducting such auctions. The Company does not believe that such regulations, which were adopted prior to the advent of the Internet, govern the operations of the Company's business nor have any claims been filed by any state implying that the Company is subject to such legislation. There can be no assurance, however, that a state will not attempt to impose these regulations upon the Company in the future or that such imposition will not have a material adverse effect on the Company's business, results of operations and financial condition.

Several states have also proposed legislation that would limit the uses of personal user information gathered online or require online services to establish privacy policies. The Federal Trade Commission has also initiated action against at least one online service regarding the manner in which personal information is collected from users and provided to third parties. Changes to existing laws or the passage of new laws intended to address these issues, including some recently proposed changes, could create uncertainty in the marketplace that could reduce demand for the services of the Company or increase the cost of doing business as a result of litigation costs or increased service delivery costs, or could in some other manner have a material adverse effect on the Company's business, results of operations and financial condition. In addition, because the Company's services are accessible worldwide, and the Company facilitates sales of goods to users worldwide, other jurisdictions may claim that the Company is required to qualify to do business as a foreign corporation in a particular state or foreign country. The Company is qualified to do business in two states in the United States, and failure by the Company to qualify as a foreign corporation in a jurisdiction where it is required to do so could subject the Company to taxes and penalties for the failure to qualify and could result in the inability of the Company to enforce contracts in such jurisdictions. Any such new legislation or regulation, or the application of laws or regulations from jurisdictions whose laws do not currently apply to the Company's business, could have a material adverse effect on the Company's business, results of operations and financial condition. See "Business--Government Regulation" and "--Privacy Policy."

SALES AND OTHER TAXES

The Company does not collect sales or other similar taxes in respect of goods sold by users through the eBay service. However, one or more states may seek to impose sales tax collection obligations on out-of-state companies such as the Company which engage in or facilitate online commerce, and a number of proposals have been made at the state and local level that would impose additional taxes on the sale of goods and services through the Internet. Such proposals, if adopted, could substantially impair the growth of electronic commerce, and could adversely affect the Company's opportunity to derive financial benefit from such activities. Moreover, a successful assertion by one or more states or any foreign country that the Company should collect sales or other taxes on the exchange of merchandise on its system could have a material adverse effect on the Company's business, results of operations and financial condition.

Legislation limiting the ability of the states to impose taxes on Internet- based transactions has been proposed in the U.S. Congress. There can be no assurance that this legislation will ultimately be enacted into law or that the final version of this legislation will not contain a limited time period in which such tax moratorium will apply. In the event that the tax moratorium is imposed for a limited time period, there

16

can be no assurance that the legislation will be renewed at the end of such period. Failure to enact or renew this legislation could allow various states to impose taxes on Internet-based commerce and the imposition of such taxes could have a material adverse affect on the Company's business, results of operations and financial condition.

RISKS ASSOCIATED WITH INTERNATIONAL OPERATIONS

A component of the Company's strategy is to expand internationally. Expansion into the international markets will require management attention and resources. The Company has limited experience in localizing its service, and the Company believes that many of its competitors are also undertaking expansion into foreign markets. There can be no assurance that the Company will be successful in expanding into international markets. In addition to the uncertainty regarding the Company's ability to generate revenues from foreign operations and expand its international presence, there are certain risks inherent in doing business on an international basis, including, among others, regulatory requirements, legal uncertainty regarding liability, tariffs, and other trade barriers, difficulties in staffing and managing foreign operations, longer payment cycles, different accounting practices, problems in collecting accounts receivable, political instability, seasonal reductions in business activity and potentially adverse tax consequences, any of which could adversely affect the success of the Company's international operations. To the extent the Company expands its international operations and has additional portions of its international revenues denominated in foreign currencies, the Company could become subject to increased risks relating to foreign currency exchange rate fluctuations. There can be no assurance that one or more of the factors discussed above will not have a material adverse effect on the Company's future international operations and, consequently, on the Company's business, results of operations and financial condition. See "Management's Discussion and Analysis of Financial Condition and Results of Operations" and "Business--eBay Strategy."

PROTECTION AND ENFORCEMENT OF INTELLECTUAL PROPERTY RIGHTS

The Company regards the protection of its copyrights, service marks, trademarks, trade dress and trade secrets as critical to its future success and relies on a combination of copyright, trademark, service mark and trade secret laws and contractual restrictions to establish and protect its proprietary rights in products and services. The Company has entered into confidentiality and invention assignment agreements with its employees and contractors, and nondisclosure agreements with parties with which it conducts business in order to limit access to and disclosure of its proprietary information. There can be no assurance that these contractual arrangements or the other steps taken by the Company to protect its intellectual property will prove 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 and service marks in the U.S. and internationally. Effective trademark, service mark, copyright and trade secret protection may not be available in every country in which the Company's services are made available online. The Company has licensed in the past, and expects that it may license in the future, certain of its proprietary rights, such as trademarks or copyrighted material, to third parties. While the Company attempts to ensure that the quality of the eBay brand is maintained by such licensees, there can be no assurance that such licensees will not take actions that might materially adversely affect the value of the Company's proprietary rights or reputation, which could have a material adverse effect on the Company's business, results of operations and financial condition. The Company also relies on certain technologies that it licenses from third parties, such as Oracle Corporation ("Oracle"), Microsoft and Sun Microsystems Inc. ("Sun"), the suppliers of key database technology, the operating system and specific hardware components for the eBay service. There can be no assurance that these third-party technology licenses will continue to be available to the Company on commercially reasonable terms. The loss of such technology could require the Company to obtain substitute technology of lower quality or performance standards or at greater cost, which could materially adversely affect the Company's business, results of operations and financial condition.

17

To date, the Company has not been notified that its technologies infringe the proprietary rights of third parties, but there can be no assurance that third parties will not claim infringement by the Company with respect to past, current or future technologies. The Company expects that participants in its markets will be increasingly subject to infringement claims as the number of services and competitors in the Company's industry segment grows. Any such claim, whether meritorious or not, could be time-consuming, result in costly litigation, cause service upgrade delays or require the Company to enter into royalty or licensing agreements. Such royalty or licensing agreements might not be available on terms acceptable to the Company or at all. As a result, any such claim could have a material adverse effect upon the Company's business, results of operations and financial condition. See "Business--Intellectual Property Rights."

YEAR 2000 IMPLICATIONS

Many current installed computer systems and software products are coded to accept only two-digit entries in the date code field and cannot reliably distinguish dates beginning on January 1, 2000 from dates prior to the year 2000. Many companies' software and computer systems may need to be upgraded or replaced in order to correctly process dates beginning in 2000 and to comply with the "Year 2000" requirements. The Company has reviewed its internal programs and has determined that there are no significant Year 2000 issues within the Company's systems or services. However, although the Company believes that its systems are Year 2000 compliant, the Company utilizes third- party equipment and software that may not be Year 2000 compliant. Failure of such third-party equipment or software to properly process dates for the year 2000 and thereafter could require the Company to incur unanticipated expenses to remedy any problems, which could have a material adverse effect on the Company's business, results of operations and financial condition. See "Management's Discussion and Analysis of Financial Condition and Results of Operations."

POSSIBLE VOLATILITY OF STOCK PRICE

The trading price of the Common Stock is likely to be highly volatile and could be subject to wide fluctuations in response to factors such as actual or anticipated variations in the Company's quarterly operating results, announcements of technological innovations, or new services by the Company or its competitors, changes in financial estimates by securities analysts, conditions or trends in the Internet and online commerce industries, changes in the market valuations of other Internet or online service companies, announcements by the Company or its competitors of significant acquisitions, strategic partnerships, joint ventures or capital commitments, additions or departures of key personnel, sales of Common Stock or other securities of the Company in the open market and other events or factors, many of which are beyond the Company's control. Further, the stock markets in general, and the Nasdaq National Market and the market for Internet-related and technology companies in particular, have experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of such companies. The trading prices of many technology companies' stocks are at or near historical highs and reflect valuations substantially above historical levels. There can be no assurance that these trading prices and valuations will be sustained. These broad market and industry factors may materially and adversely affect the market price of the Common Stock, regardless of the Company's operating performance. Market fluctuations, as well as general political and economic conditions such as recession or interest rate or currency rate fluctuations, may also adversely affect the market price of the Common Stock. In the past, following periods of volatility in the market price of a company's securities, securities class-action litigation has often been instituted against such company. Such litigation, if instituted, could result in substantial costs and a diversion of management's attention and resources, which would have a material adverse effect on the Company's business, results of operations and financial condition.

CONTROL BY PRINCIPAL STOCKHOLDERS, EXECUTIVE OFFICERS AND DIRECTORS

Upon completion of this offering, the Company's executive officers and directors (and their affiliates) will, in the aggregate, own approximately % of the Company's outstanding Common Stock ( % if the Underwriters' over- allotment option is exercised in full). As a result, such persons, acting together, will have the ability to control all matters submitted to stockholders of the Company for approval (including the election and removal of directors and any merger, consolidation or sale of all or substantially all of the Company's assets) and to control the management and affairs of the Company. Accordingly, such concentration of ownership may have the effect of delaying, deferring or preventing a change in control of the Company, impede a merger, consolidation, takeover or other business combination involving the Company or discourage a potential acquirer from making a tender offer or otherwise attempting to obtain control of the Company, which in turn could have an adverse effect on the market price of the Company's Common Stock. See "Management" and "Principal and Selling Stockholders."

FUTURE CAPITAL NEEDS

The Company currently anticipates that the net proceeds of this offering, together with its available funds, will be sufficient to meet its anticipated needs for working capital, capital expenditures and business expansion through at least the next 18 months. Thereafter, the Company may need to raise additional funds. The Company may need to raise additional funds sooner in order to fund more rapid expansion, to develop new or enhanced services or products, to respond to competitive pressures or to acquire complementary products, businesses or technologies. If additional funds are raised through the issuance of equity or convertible debt securities, the percentage ownership of the stockholders of the Company will be reduced, stockholders may experience additional dilution and such securities may have rights, preferences and privileges senior to those of the Company's Common Stock. There can be no assurance that additional financing will be available on terms favorable to the Company or at all. If adequate funds are not available or are not available on acceptable terms, the Company may not be able to fund its expansion, take advantage of unanticipated acquisition opportunities, develop or enhance services or products or respond to competitive pressures. Such inability could have a material adverse effect on the Company's business, results of operations and financial condition. See "Use of Proceeds" and "Management's Discussion and Analysis of Financial Conditions and Results of Operations--Liquidity and Capital Resources."

SHARES ELIGIBLE FOR FUTURE SALE

Sales of substantial amounts of the Company's Common Stock (including shares issued upon the exercise of outstanding options) in the public market after this offering could adversely affect the market price of the Common Stock. Such sales also might make it more difficult for the Company to sell equity or equity-related securities in the future at a time and price that the Company deems appropriate. In addition to the shares of Common Stock offered hereby (assuming no exercise of the Underwriters' over-allotment option), as of the date of this Prospectus, there will be 36,249,801 shares of Common Stock outstanding, all of which are restricted securities ("Restricted Securities") under the Securities Act of 1933, as amended (the "Securities Act"). As of such date, no Restricted Securities will be eligible for sale in the public market, and Restricted Securities will remain subject to the Company's right to repurchase such shares at the original purchase price. Following the expiration of 120-day lock-up agreements with the representatives of the Underwriters, 23,671,779 Restricted Securities will be available for sale in the public market (excluding those that remain subject to the right of repurchase) and the remaining Restricted Securities will be eligible for sale from time to time thereafter upon expiration of applicable holding periods under Rule 144 under the Securities Act and the Company's right to repurchase unvested shares. In addition, as of June 30, 1998, there were outstanding options to purchase 1,071,159 shares of the Company's Common Stock, all of which were exercisable. Substantially, all of the shares issuable upon exercise of such options will be subject to

19

lock-up agreements. The representatives of the several underwriters acting together may, in their sole discretion and at any time without notice, release all or any portion of the securities subject to lock-up agreements. In addition, the holders of 29,629,425 Restricted Securities are entitled to certain rights with respect to registration of such shares for sale in the public market. If such holders sell in the public market, such sales could have a material adverse effect on the market price of the Company's Common Stock.

Immediately after this offering, the Company intends to register approximately 7,032,659 shares of Common Stock subject to outstanding options and reserved for issuance under its stock option and purchase plans. See "Shares Eligible for Future Sale."

CERTAIN ANTI-TAKEOVER PROVISIONS

Upon the closing of this offering, the Company's Board of Directors will have the authority to issue up to 5,000,000 shares of Preferred Stock and to determine the price, rights, preferences, privileges and restrictions, including voting rights, of those shares without any further vote or action by the stockholders. The rights of the holders of Common Stock will be subject to, and may be adversely affected by, the rights of the holders of any Preferred Stock that may be issued in the future. The issuance of Preferred Stock, while providing flexibility in connection with possible acquisitions and other corporate purposes, could have the effect of delaying, deferring or preventing a change in control of the Company, may discourage bids for the Company's Common Stock at a premium over the market price of the Common Stock, and may adversely affect the market price of, and the voting and other rights of the holders of, the Common Stock. The Company has no current plans to issue shares of Preferred Stock. In addition, certain provisions of the Company's Amended and Restated Certificate of Incorporation and Bylaws, including provisions that divide the Board of Directors into three classes to serve staggered three-year terms, prohibit the stockholders from taking action by written consent and restrict the ability of stockholders to call special meetings, may also make it more difficult for a third party to acquire a majority of the Company's voting stock or effect a change in control of the Company. The Company is also subject to certain provisions of Delaware law that could have the effect of delaying, deterring or preventing a change in control of the Company, including Section 203 of the Delaware General Corporation Law, which prohibits a Delaware corporation from engaging in any business combination with any interested stockholder for a period of three years from the date the person became an interested stockholder unless certain conditions are met. In addition, the Company's certificate of incorporation and bylaws contain certain provisions that, together with the ownership position of the Company's executive officers and directors and their affiliates, could discourage potential takeover attempts and make more difficult attempts by stockholders to change management which could adversely affect the market price of the Company's Common Stock. See "Description of Capital Stock."

BROAD MANAGEMENT DISCRETION OVER ALLOCATION OF PROCEEDS

The net proceeds to the Company from the sale of the shares of Common Stock offered hereby at an assumed initial public offering price of $ per share, after deducting the estimated underwriting discount and estimated offering expenses, are estimated to be approximately $ million. The primary purposes of this offering are to obtain additional capital, create a public market for the Common Stock and facilitate future access to public markets. The Company expects to use the net proceeds primarily for working capital, to repay certain indebtedness and for other general corporate purposes. A portion of the net proceeds also may be used to acquire or invest in complementary businesses, technologies, products or services. Accordingly, the Company's management will retain broad discretion as to the allocation of the proceeds of this offering. The failure of management to apply such funds effectively could have a material adverse effect on the Company's business, results of operations and financial condition. See "Use of Proceeds."

20

NO PRIOR MARKET FOR COMMON STOCK

Prior to this offering, there has been no public market for the Company's Common Stock, and there can be no assurance that an active public market will develop or be sustained after this offering or that investors will be able to sell the Common Stock should they desire to do so. The initial public offering price will be determined by negotiations between the Company and the representatives of the Underwriters and may bear no relationship to the price at which the Common Stock will trade upon completion of this offering. See "Underwriting" for a discussion of the factors to be considered in determining the initial public offering price.

IMMEDIATE AND SUBSTANTIAL DILUTION

The initial public offering price is substantially higher than the net tangible book value per outstanding share of Common Stock. Purchasers of the Common Stock in this offering will suffer immediate and substantial dilution of $ per share in the net tangible book value of the Common Stock from the initial public offering price. To the extent that outstanding options to purchase the Company's Common Stock are exercised, there may be further dilution. See "Dilution."

21

USE OF PROCEEDS

The net proceeds to the Company from the sale of the shares of Common Stock offered by the Company hereby are estimated to be approximately $ million
(approximately $ million if the over-allotment option is exercised in full)
at an assumed initial public offering price of $ per share and after deducting the estimated underwriting discount and estimated offering expenses. The primary purposes of this offering are to obtain additional capital, create a public market for the Common Stock and facilitate future access to public markets. The Company will not receive any proceeds from the sale of the Common Stock by the Selling Stockholder.

The Company intends to use substantially all of the net proceeds of this offering for general corporate purposes, including working capital. The Company also intends to use a portion of the net proceeds to repay all outstanding indebtedness under a bank credit line ($431,000 at June 30, 1998). This credit line matures on January 5, 2000 and bears interest at the bank's prime rate plus 1.25%. The Company may also use a portion of the net proceeds, currently intended for general corporate purposes, to acquire or invest in businesses, technologies or products that are complementary to the Company's business. The Company has no present plans or commitments and is not currently engaged in any negotiations with respect to such transactions that are material. Pending such uses, the Company intends to invest the net proceeds from this offering in short-term, interest-bearing, investment-grade securities. The Company will have significant discretion as to the use of the net proceeds from this offering. See "Risk Factors--Future Capital Needs" and "--Broad Management Discretion Over Allocation of Proceeds."

DIVIDEND POLICY

The Company has not declared or paid any cash dividends on its capital stock and does not anticipate paying any cash dividends in the foreseeable future. In addition, the terms of the Company's credit line prohibit the payment of cash dividends on its capital stock.

22

CAPITALIZATION

The following table sets forth the capitalization of the Company as of June 30, 1998: (i) on an actual basis; (ii) on a pro forma basis to reflect the conversion of all outstanding shares of Preferred Stock into Common Stock upon the closing of this offering; and (iii) on a pro forma as adjusted basis to reflect this conversion and the application of the net proceeds from the sale of the shares of Common Stock offered by the Company hereby at an assumed initial public offering price of $ per share and after deducting the estimated underwriting discount and estimated offering expenses.
