Our actual results could differ materially from those indicated in such forward-looking statements. Factors that could cause or contribute to such differences include, but are not limited to, uncertainty in future operating results, uncertainty in the secure proxy appliance market, increased competition, downturn in macroeconomic conditions, inability to raise additional capital, inability to implement our distribution strategy, inability to introduce new products, increased litigation, failure to comply with Nasdaq’s listing standards, inability to attract and retain key employees, fluctuations in quarterly operating results, product concentration, technological changes, and other risks discussed in this item under the heading “Factors Affecting Future Operating Results” and the risks discussed in our other recent Securities and Exchange Commission filings.

Overview

Blue Coat^™ Systems, Inc., also referred to in this report as “we” or the “Company”, was incorporated in Delaware on March 16, 1996 as CacheFlow^® Inc. On August 21, 2002, we changed our name from CacheFlow Inc. to Blue Coat Systems, Inc. and this filing and all future SEC filings will be under the name Blue Coat Systems, Inc. The ticker symbol for our common stock was also changed from CFLO to BCSI.

On September 16, 2002, we filed an amendment to our Certificate of Incorporation, implementing a one-for-five reverse split of our outstanding common stock. Our common stock began trading under the split adjustment at the opening of the Nasdaq Stock Market on September 16, 2002. Our number of authorized shares of common stock, however, remains at 200 million. We continue to have 10 million authorized but unissued shares of preferred stock. All share and per share amounts in this Annual Report on Form 10-K and in the accompanying consolidated financial statements and notes thereto reflect the reverse stock split for all periods presented.

We are focused on the secure proxy appliance market. Our secure proxy appliances, called ProxySGs, serve as a point of control and integration for multiple Web security functions. Our products are designed to enable enterprises to minimize security risks and reduce the management costs and complexity of their Web infrastructure.

Our initial products, introduced in May of 1998, utilized caching technology to improve user response time for accessing Internet content. These systems were used by service providers and enterprises throughout the world and achieved a market leadership position. By 1999, the caching market began evolving into two distinct markets—enterprises looking for proxy caches to securely connect employees to the Internet, and service providers looking for increased bandwidth savings and response time for their subscribers. During this timeframe, service provider customers represented the majority of our revenues. We continued, however, to enhance our competitive position in both markets through internal development and external acquisitions. By early 2001, the demand for extending our enterprise proxy caches started to grow, while the service provider market decreased significantly. We accelerated our development and marketing efforts around our enterprise business, resulting in the launch of our ProxySG^™ products in February 2002.

Convergence around Web protocols and their related security threats has made organizations understand the business consequences of an inadequate security infrastructure. Many of these organizations are rethinking

existing Internet connectivity and security services that have evolved rapidly without the benefit of a coherent architecture, resulting in complex infrastructures that are difficult to scale and manage. To protect their businesses, these enterprise organizations need the capability to easily understand and control what is happening via the Web. This capability is enabled by a new layer of security infrastructure, called a secure proxy appliance, which serves as a point of control and integration for multiple Web security functions.

Blue Coat Solutions

Our suite of products provide customers with application-level security, policy-based control capabilities, comprehensive management and reporting functionality for applications such as authorization management, Web usage monitoring, proxy caching services, content filtering, virus scanning, content security, and instant messaging control. Our products enable businesses to reduce security risks and the management costs and complexity of their Web infrastructure.

Authorization Management

An effective enterprise security infrastructure begins with authentication, authorization and accounting. These services are the starting point for user and content protection and control. The first step, authentication, is to determine the identity of the requestor as it relates to a given request for access. Once the system determines the identity for a given request, the next step, authorization, is to associate policy with the identified user. In short, authorization governs what resources a user can access and what a user can do with those resources based on a set of rules. Systems that grant access to resources must also effectively track the use of those resources. This accounting information is necessary to effectively audit events in the case of fraud, malicious use, or to determine proof. Our ProxySG provides a powerful authentication, authorization and accounting system for Web protection and control. ProxySG supports cross-organizational authentication to multiple security databases or directories. Once users are identified, other conditions can be examined to determine the access privileges for a given request. The ProxySG appliance provides the power to define one set of rules for protection and control, and to tie those rules to any number of policy conditions—all without redefining users in yet another management directory/database. The ProxySG uses an authenticated user identifier to trigger a certain action or rule. Requests can be authorized based on any combination of known identifiers. In addition, all requests through the ProxySG are logged, providing detailed accounting information. This gives the visibility necessary to determine Web usage patterns, audit user history, track security issues and develop comprehensive Web protection and control policy.

Web Usage Monitoring

Our ProxySG provides a robust and flexible way to monitor users and audit Web and streaming traffic for both external and internal content requests. The flexible logging features of the ProxySG, coupled with integrated authentication and identification capabilities, give organizations the power to monitor Web access for every user in the network at any time, regardless of where they are. Internet access traffic flowing through the ProxySG gives administrators and managers the ability to audit Web traffic as needed. This processing point gives a robust picture of the Web usage for the entire network or specific information on individual or department usage patterns. These logs can be made available both in real time and on a scheduled basis. Because ProxySG logs are standardized, customers can choose from a variety of commonly available reporting tools or use the Blue Coat Reporter, described further on page 7.

Proxy Caching Services

To maximize employee productivity, organizations need to ensure a high quality Internet experience for users. In addition, enterprises need to implement content and user policies to manage Web traffic growth, while effectively using network resources. At the same time, corporate security cannot be compromised and Internet performance cannot be allowed to degrade. First generation proxy servers—software-based applications running

on general-purpose operating systems—offered a point of control for securing network access, but their performance degrades under today’s heavy Internet and intranet usage. Blue Coat’s secure proxy appliances provide next-generation proxy functionality that delivers business and technology benefits to Web-dependent enterprises.

Configured as a proxy caching server deployed between corporate users and the Internet, these optimized appliances intelligently manage user requests for content. When a user selects a URL, the request goes first to the Blue Coat secure proxy appliance for authentication and authorization. If the objects from the requested page are already in cache on the Blue Coat appliance, they are immediately served to the user. If the objects are not stored locally, the Blue Coat security appliance acts as a proxy for the user by communicating to the origin server via the Internet. When the objects are returned from the origin server a copy is delivered to the user and also stored on the system’s cache to serve all subsequent requests. The entire transaction is monitored and logged for reporting and planning purposes.

Blue Coat’s unique Web Knowledge Framework allows enterprises to handle nearly all Web protocols, including HTTP, HTTPS, FTP, Microsoft streaming (MMS and HTTP streaming), Real streaming (RTSP and HTTP streaming), QuickTime streaming (over RTSP), MP3, Flash, and hundreds of other Web object types

Content Filtering

To realize all the benefits the Internet offers, companies need to enforce Internet access policies to prevent employees from accessing inappropriate or unproductive content. The first step in implementing company-wide Internet access policy is Web usage monitoring, or understanding which users are doing what with their company-provided Web access. Once security and network management personnel have an understanding of what kinds of use and misuse are occurring on the network, the next step is to provide enforcement for corporate Web access policy. This enforcement requires the ability to identify and match users with Web access policies. Our ProxySG appliances provide a robust and flexible way to enforce Internet access policies based on content categories (gambling, sex, etc.), content type (http, ftp, streaming, etc.), identity (user, group, etc.), or network conditions. Turning on these multiple combinations of policy requires a unique level of performance. Software-only solutions cannot scale to enterprise demands with this kind of granularity enabled. Our ProxySG makes it possible by integrating our policy architecture, specialized operating system and network hardware, and a cache that stores commonly accessed content for reuse. Our ProxySG appliances provide the performance and manageability required for enterprise-wide policy-based content filtering.

Virus Scanning

Our ProxySG appliances provide a robust and flexible way to block viruses from Web protocols inside and outside the firewall. The ProxySG’s architecture is designed for handling Web requests that require scanning for potentially malicious mobile code and viruses. ProxySG appliances use the standard Internet Content Adaptation Protocol, ICAP, to vector responses to virus scanning servers from other vendors to deliver unmatched flexibility and performance in scanning Web content. In this way, organizations can define multiple scanning services for specific functions. Administrators can set flexible virus scanning policies based on specific destination domain, URL, file extension or mime type. The ability to choose the right service for the job provides security administrators with the tools to scale virus scanning infrastructure for Web requests as needed. In combination with the ability to block by content type and scan Web protocols for malicious code, ProxySG appliances can effectively sanitize Web content. ProxySG appliances also scale a company’s virus scanning capability in several ways. First, storing scanned Web content for reuse effectively eliminates the need to rescan every request. Once data is deemed safe, it is available for subsequent requests without the delay that would normally result from a rescan of the same content. Second, ProxySG appliances can load-balance scanning requests across multiple scanning servers, allowing security administrators to add scanning capacity as needed. Finally, ProxySG appliances automatically detect virus pattern updates on the virus scanning servers and mark content for rescan as necessary. ProxySG appliances are compatible with leading virus scanning solutions, including ICAP versions of Symantec’s CarrierScan Server and Trend Micro’s InterScan Server.

Content Security

Our ProxySG products give security professionals the tools necessary to protect and control the network from a variety of new Web-based threats. In addition, the ProxySG provides the visibility and flexible content policy capabilities needed to respond in cases where a security breach has occurred. With our ProxySG appliances, security administrators can:

Instant Messaging Control

Instant Messaging (IM) usage has become commonplace within the enterprise and continues to increase. Each month employees install free IM software from AOL, Microsoft or Yahoo! to “chat” with peers, business colleagues and friends using the company network. Unauthorized use of these applications raises many valid security and productivity concerns among IT managers and security officers. Blue Coat Systems enables organizations to secure and control the IM applications already in use—providing the granular access control, security and logging required for enterprise-class messaging solutions with the software that is already on users’ desktops. Blue Coat’s IM security products control users and their utilization of public IM applications including AOL IM, Yahoo IM, and Microsoft’s MSN Messaging products. Blue Coat’s granular policy architecture controls not only which users are allowed to utilize Instant Messaging, but which IM protocols are allowed, what features are to be enabled, to whom they may IM or chat with (inside the company and/or outside the company), what time of the day they can IM, how logging should be handled, and much more. Enterprises can leverage their existing authentication infrastructure and all of the power and flexibility of Blue Coat’s secure proxy appliance to handcuff unauthorized IM usage on the corporate network.

Products

We call our secure proxy appliances ProxySGs. We manufacture three main types of ProxySG appliances, the ProxySG 400 Series, the ProxySG 800 Series and the ProxySG 6000 Series. These three types of ProxySG appliances are very similar in terms of functionality, and differ mainly in terms of their performance characteristics and scalability. We currently license two separate software products, third party URL filtering software and Blue Coat Reporter, which are used in conjunction with our ProxySG appliances. We also manufacture an appliance called Director, which is used primarily to manage large numbers of ProxySG appliances in a customer’s environment. Lastly, we currently still sell several legacy products, our model 700 and model 7000 server accelerators, and 6000 series client accelerators.

technology. The ProxySG acts in concert with existing routers, firewalls and servers to reduce the complexity and management cost of Web security and eliminate the need to trade-off best practices security for Web performance.

Our ProxySG appliances are comprised of a specialized hardware platform and our operating system (SGOS). Our specialized hardware platforms provide security, scalability and performance in an easy to deploy form factor that is typically rack mounted, while SGOS provides the security and control application functionality enterprises require to protect their Web-enabled networks. List prices for our ProxySG and associated products range from $3,495 to $150,000.

ProxySG 400 Series

The ProxySG 400 is specifically designed to increase security and reduce costs associated with regional and branch office Web protection. Delivered as a rack mountable or desktop device, the ProxySG 400 platform easily drops in to remote environments where technical support staff is not always available. The ProxySG 400 is available in two fixed configurations, one with a single 40gigabyte (GB) disk drive and 256 megabytes (MB) of random access memory (RAM), and the other with two 40 GB disk drives and 512 MB of RAM.

ProxySG 800 Series

The ProxySG 800 is an easy to manage appliance that installs in minutes with little ongoing maintenance. The systems include removable, hot-swappable disk drives. Specific configurations range from systems with a single 18 GB disk drive and 512 MB of RAM to systems with four 73 GB disk drives and 2GB of RAM.

ProxySG 6000 Series

The ProxySG 6000 provides a high-end solution with greater expandability for locations where high bandwidth and throughput are required. Specific configurations range from systems with two 36 GB disk drives and 768 MB of RAM to systems with eight 73 GB disk drives and 4 GB of RAM.

Visual Policy Manager

Blue Coat’s Visual Policy Manager provides a graphical way to develop and implement an organization’s Web security policies. With Visual Policy Manager, security and network administrators can quickly create policy rules that leverage the flexible policy architecture of the ProxySG. The Visual Policy Manager software is included as part of SGOS.

URL Filtering

Our URL Filtering solutions integrate our appliance with software from leading content filtering vendors allowing organizations to improve productivity, reduce legal liability, and conserve bandwidth by automatically determining which Web sites to block as well as continually updating the lists of restricted sites. By leveraging the ProxySG policy framework, organizations can restrict access to Internet sites by user, group, time of day, bandwidth, and other factors. In addition, because the ProxySG can cache frequently requested content, redundant requests from authorized users for acceptable URLs are served from the ProxySG, reducing network bandwidth utilization and improving the end-user’s quality of experience.

Reporter

The Blue Coat Reporter is a powerful log processing and reporting product that generates out-of-the-box reports tailored for the ProxySG. Reporter provides identity-based user and network reporting that helps evaluate Web security policies and resource management. Because it is Web-based and cross-platform, it gives companies the flexibility to view Web usage reports from anywhere administrators or managers have access to a network connection and a Web browser.

These products are designed as integrated appliances, combining specialized hardware platforms with our tightly coupled CacheOS operating system. They are deployed between users and the Internet, and intelligently manage requests for Web and multimedia content.

Our Key Strategies

Our objective is to be the leading provider of secure proxy appliance solutions by delivering high-performance, innovative ProxySG appliances. Key elements of our strategy include the following:

Apply our ProxySG Focus to the Enterprise Market Segment.    We are focused exclusively on developing ProxySG appliances. We believe this focus helps us to rapidly identify and target attractive market opportunities. We are directing our product development, marketing and sales activities at the enterprise market segment, which we believe represents the most attractive opportunity based on a demonstrated need for secure proxy appliances, the opportunity to sell to numerous customers and the level of existing competition.

Enhance Capabilities of our ProxySG.    We intend to use our technological expertise to meet the needs of the evolving secure proxy appliance market. We plan to continue to develop both the software and hardware elements of our solution to gain and maintain a competitive advantage and expand the market for our products. Our additional efforts to enhance the capabilities of our ProsySG appliances include adding more functionality to secure and control new emerging applications, enhancing security for emerging Web threats and increasing the price performance of our appliances.

Focus on Indirect Distribution Channels.    We intend to focus our product distribution strategy around the use of distributors and resellers rather than a direct sales force. Enterprises have historically purchased security products from distributors and resellers, and we believe that we can improve our sales coverage and sales force

8

Table of Contents

productivity through expanding the use of distributors and resellers as distribution channels. Historically, virtually all of our international sales have been made through resellers, while domestically we have relied more heavily on a direct sales force. We intend to increase the use of distributors and resellers in our domestic market and reduce our reliance on direct sales.

Sales and Marketing

We utilize a combination of our direct sales force, resellers, systems integrators and distributors as appropriate for each of our target markets. Our domestic business, which historically has been predominately direct, is in the process of leveraging distribution channels consistent with our evolving business strategy. Our international business continues to be almost exclusively indirect. We believe it is important to maintain our international presence and continue to develop products and services to address international markets. We support our distribution channels with systems engineers and customer support personnel that provide technical service and support to our customers. We have entered into agreements with resellers and distributors such as Westcon, Allasso, Nissho Electronics and others.

Our marketing efforts focus on increasing market awareness of our products and technology and on promoting the Blue Coat brand. Our strategy is to create this awareness through marketing programs that distinguish our products based on their features and functionality. We have a number of marketing programs to support the sale and distribution of our products and to inform existing and potential customers within our target market segments about the capabilities and benefits of our products. Our marketing efforts include participation in industry tradeshows, informational seminars, preparation of competitive analyses, sales training, maintenance of our Web site, advertising and public relations.

Research and Development

We believe that strong product development capabilities are essential to the continued success and growth of the Company. Our research and development efforts are focused on developing new products as well as improvements and enhancements to our existing products. Research and development expenses were $11.4 million, $35.1 million and $27.7 million for the fiscal years ended April 30, 2003, 2002 and 2001, respectively.

Our research and development team consists of engineers with extensive backgrounds in operating systems, algorithms, computer science, streaming media and network engineering. We believe that the experience and capabilities of our research and development professionals represents a competitive advantage for the Company. We also work closely with our customers in developing and enhancing our products. Our current research and development efforts are primarily focused on enhancing the capabilities of our current secure proxy appliances by adding new features and strengthening existing features.

The market for secure proxy appliances is evolving rapidly. In order to stay competitive, we must make significant investments in research and development based on what we perceive to be the direction of the market. We currently spend a significant amount of our resources on research and development projects and plan to continue to do so for the foreseeable future. Current research and development projects will enhance the Company’s position in the marketplace only if the secure proxy appliance market matures as we anticipate. Failure on our part to anticipate the direction of the market and develop product that meets those emerging needs will seriously impair our business, financial condition, and results of operations.

We expect that most of the enhancements to our existing and future products will be accomplished by internal development. However, we currently license some technologies and will continue to evaluate externally developed solutions for integration into our products.

Manufacturing

We currently outsource, to third parties, the manufacturing of all of the subassemblies and components of our secure proxy appliances, including printed circuit boards, custom power supplies, chassis, cables and subassemblies. We perform the majority of final assembly and testing ourselves. This approach allows us to reduce our investment in manufacturing capital and to take advantage of the expertise of our vendors. Our internal manufacturing operations consist primarily of prototype development, materials planning and procurement, final assembly, testing and quality control. Our standard parts and components are generally available from more than one vendor while our custom parts are usually single sourced. We typically obtain these components through purchase orders and currently do not have contractual relationships or guaranteed supply arrangements with these suppliers. If one of these vendors ceased to provide us with necessary parts and components, we would likely encounter delays in product production as we make the transition to another vendor, which would seriously harm our business. Furthermore, if actual orders do not match our forecasts (as we have experienced in the past), we may have excess or inadequate inventory of some materials and components or we could incur cancellation charges or penalties, which would increase our costs or prevent or delay product shipments and could seriously harm our business.

Competition

The market for secure proxy appliances is intensely competitive, evolving and subject to rapid technological change. Primary competitive factors that have typically affected our market include product characteristics such as reliability, scalability and ease of use, as well as price and customer support. The intensity of this competition is expected to increase in the future. Increased competition is likely to result in price reductions, reduced gross margins and loss of market share, any one of which could seriously harm our business. We may not be able to compete successfully against current or future competitors and we cannot be certain that competitive pressures we face will not seriously harm our business. Our competitors vary in size and in the scope and breadth of the products and services they offer. We encounter competition from a variety of companies, including Cisco Systems, Network Appliance and various others. In addition, we expect additional competition from other established and emerging companies as the market for secure proxy appliances continues to develop and expand.

Many of our current and potential competitors have longer operating histories, significantly greater financial, technical, marketing and other resources, significantly greater name recognition and a larger installed base of customers than we do. In addition, many of our competitors have well-established relationships with our current and potential customers and have extensive knowledge of our industry. As a result, our competitors may be able to respond more quickly to new or emerging technologies and changes in customer requirements, or to devote greater resources to the development, marketing, promotion and sale of their products than we can. Current and potential competitors have established or may establish cooperative relationships among themselves or with third parties to increase the market acceptance of their products. In addition, our competitors may be able to replicate our products, make more attractive offers to existing and potential employees and strategic partners, more quickly develop new products or enhance existing products and services, or bundle secure proxy appliances in a manner that we cannot provide. Accordingly, it is possible that new competitors or alliances among competitors may emerge and rapidly acquire significant market share. We also expect that competition will increase as a result of industry consolidation.

Intellectual Property and Other Proprietary Rights

We depend significantly on our ability to develop and maintain the proprietary aspects of our technology. To protect our proprietary technology, we rely primarily on a combination of contractual provisions, confidentiality procedures, trade secrets, copyright and trademark laws and patents. Despite our efforts to protect our proprietary rights, unauthorized parties may attempt to copy aspects of our products or obtain and use information that we regard as proprietary. Policing unauthorized use of our products is difficult. In addition, the laws of some foreign countries do not protect our proprietary rights to as great an extent as do the laws of the United States. Our means of protecting our proprietary rights may not be adequate and our competitors may

10

Table of Contents

independently develop similar technology, duplicate our products or design around patents that may be issued to us or our other intellectual property.

We presently have several issued patents and pending United States patent applications. Even if patents are issued, we cannot assure you that we will be able to detect any infringement or, if infringement is detected, that patents issued will be enforceable or that any damages awarded to us will be sufficient to adequately compensate us.

There can be no assurance or guarantee that any products, services or technologies that we are presently developing, or will develop in the future, will result in intellectual property that is protectable under law, whether in the United States or a foreign jurisdiction, that this intellectual property will produce competitive advantage for us, or that the intellectual property of competitors will not restrict our freedom to operate or put us at a competitive disadvantage.

We rely on technology that we license from third parties, including software that is integrated with internally developed software and used in our products to perform key functions. For example, we license subscription-filtering technology from Secure Computing. If we are unable to continue to license any of this software on commercially reasonable terms, we will face delays in releases of our software or will be required to drop this functionality from our software until equivalent technology can be identified, licensed or developed, and integrated into our current product. Any of these delays could seriously harm our business.

There has been a substantial amount of litigation in the technology industry regarding intellectual property rights and we are currently defending a suit, which alleges infringement of certain United States patents by us (See Item 8, Note 13 “Litigation” of the consolidated financial statements included in this Annual Report on Form 10-K). While we believe the case is without merit, it does show it is possible that third parties may claim that we, or our current or potential future products, infringe their intellectual property. We expect that companies in the Internet and networking industries will increasingly be subject to infringement claims as the number of products and competitors in our industry segment grows and the functionality of products in different industry segments overlaps. Any claims, with or without merit, could be time-consuming, result in costly litigation, cause product shipment delays or require us to enter into royalty or licensing agreements. Royalty or licensing agreements, if required, may not be available on terms acceptable to us or at all, which could seriously harm our business.

Employees

As of April 30, 2003, we had a total of 195 employees, comprised of 62 in research and development, 72 in sales, 9 in marketing, 16 in customer support, 11 in manufacturing and 25 in general and administrative. Of these employees, 138 were located in North America and 57 located internationally. None of our employees are represented by collective bargaining agreements, nor have we experienced any work stoppages. We consider our relations with our employees to be good.

Our future operating results depend significantly upon the continued service of our senior management, and key technical and sales personnel, most of whom are not bound by an employment agreement. Competition for these personnel is intense, and we may not be able to retain them in the future. Our future success also depends upon our continuing ability to attract and retain highly qualified individuals. We may experience difficulties managing our financial and operating performance if we are unable to attract and retain qualified personnel.

FACTORS AFFECTING FUTURE OPERATING RESULTS

The discussion in this Annual Report on Form 10-K contains forward-looking statements that involve risks and uncertainties. The statements contained in this Report that are not purely historical are forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, including statements on revenue expectations, product acceptance, product and sales development, operating results, and cash usage, as well as statements on our expectations, beliefs, intentions or strategies regarding the future. All forward-looking statements included in this document are based on information available to us on the date hereof. We assume no obligation to update any such forward-looking statements. Our actual results could differ materially from those indicated in such forward-looking statements. Factors that could cause or contribute to such differences include, but are not limited to, uncertainty in future operating results, uncertainty in the secure proxy appliance market, increased competition, downturn in macroeconomic conditions, inability to raise additional capital, inability to implement our distribution strategy, inability to introduce new products, increased litigation, failure to comply with Nasdaq’s listing standards, inability to attract and retain key employees, fluctuations in quarterly operating results, product concentration, technological changes, and other risks discussed in this item under the heading “Factors Affecting Future Operating Results” and the risks discussed in our other recent Securities and Exchange Commission filings. Our business, financial condition and results of operations could be seriously harmed by any of the following risks. The trading price of our common stock could decline due to any of these risks.

We have a history of losses, expect to incur future losses and may never achieve profitability, which could result in the decline of the market price of our common stock.

We incurred net losses of $15.9 million, $247.0 million and $519.1 million for the years ended April 30, 2003, 2002 and 2001, respectively. As of April 30, 2003, we had an accumulated deficit of $865.1 million. We have not had a profitable quarter since our inception and we expect to continue to incur net losses on a quarterly and annual basis in the future. We expect to continue to incur significant operating expenses and, as a result, we will need to generate significant revenues if we are to achieve profitability. We may never achieve profitability.

The market for secure proxy appliance solutions is relatively new and rapidly evolving, and if this market does not develop as we anticipate, our sales may not grow and may even decline.

Sales of our products depend on increased demand for secure proxy appliances. The market for secure proxy appliances is a new and rapidly evolving market. If the market for secure proxy appliances fails to grow as we anticipate, or grows more slowly than we anticipate, our business will be seriously harmed. In addition, our business will be harmed if the market for secure proxy appliances continues to be negatively impacted by uncertainty surrounding macro-economic growth. Because this market is new, we cannot predict its potential size or future growth rate, if any.

To maintain our competitive position in a market characterized by rapid rates of technological advancement, we must continue to invest significant resources in research and development. There is no guarantee that we will accurately predict the direction in which the secure proxy appliance market will evolve. Failure on our part to anticipate the direction of the market and develop products that meet those emerging needs will significantly impair our business and operating results and our financial condition will be materially adversely affected.

We expect increased competition and, if we do not compete effectively, we could experience a loss in our market share and sales.

The market for secure proxy appliances is intensely competitive, evolving and subject to rapid technological changes. Primary competitive factors that have typically affected our market include product characteristics such as reliability, scalability and ease of use, as well as price and customer support. The intensity of competition is expected to increase in the future. Increased competition is likely to result in price reductions, reduced gross

margins and loss of market share, any one of which could seriously harm our business. We may not be able to compete successfully against current or future competitors and we cannot be certain that competitive pressures we face will not seriously harm our business. Our competitors vary in size and in the scope and breadth of the products and services they offer. We encounter competition from a variety of companies, including Cisco Systems, Network Appliance and various others. In addition, we expect additional competition from other established and emerging companies as the market for secure proxy appliances continues to develop and expand.

Many of our current and potential competitors have longer operating histories, significantly greater financial, technical, marketing and other resources, significantly greater name recognition and a larger installed base of customers than we do. In addition, many of our competitors have well-established relationships with our current and potential customers and have extensive knowledge of our industry. As a result, our competitors may be able to respond more quickly to new or emerging technologies and changes in customer requirements, or to devote greater resources to the development, marketing, promotion and sale of their products than we can. The products of our competitors may have features and functionality that our products do not have. Current and potential competitors have established or may establish cooperative relationships among themselves or with third parties to increase the market acceptance of their products. In addition, our competitors may be able to replicate our products, make more attractive offers to existing and potential employees and strategic partners, more quickly develop new products or enhance existing products and services, or bundle secure proxy appliances in a manner that we cannot provide. Accordingly, it is possible that new competitors or alliances among competitors may emerge and rapidly acquire significant market share. We also expect that competition will increase as a result of industry consolidation.

A continued downturn in macroeconomic conditions could adversely impact our existing and potential customers’ ability and willingness to purchase our products, which would cause a decline in our sales.

U.S. economic growth slowed significantly in the past two and one half years. In addition, there is uncertainty relating to the prospects for near-term U.S. economic growth, as well as the extent to which the U.S. slowdown will impact international markets. This slowdown and uncertainty contributed to delays in decision-making by our existing and potential customers and a resulting decline in our sales in the second half of fiscal 2001 and all of fiscal 2002 and 2003. Continued uncertainty or a continued slowdown could result in a further decline in our sales and our operating results could again be below our expectations and the expectations of public market analysts and investors. Our stock price has materially declined over the past two and one half years and our stock price may continue to decline in the event that we fail to meet the expectations of public market analysts or investors in the future.

If we are unable to raise additional capital, our business could be harmed.

As of April 30, 2003, we had approximately $12.8 million in cash and cash equivalents and $10.5 million in short-term investments. We believe that these amounts will enable us to meet our capital requirements for at least the next twelve months. However, if cash is used for unanticipated needs, we may need additional capital during that period. The development and marketing of new products will require a significant commitment of resources. In addition, if the market for secure proxy appliances develops at a slower pace than anticipated or if we fail to establish significant market share and achieve a meaningful level of sales, we could be required to raise substantial additional capital. We cannot be certain that additional capital will be available to us on favorable terms, or at all. If we were unable to raise additional capital when we require it, our business would be seriously harmed.

If we fail to create additional sales through our sales channel partners, our business will be seriously harmed.

We intend to focus our product distribution strategy around the use of distributors and resellers rather than a direct sales force. Enterprises have historically purchased security products from distributors and resellers, and we believe that we can improve our sales coverage and sales force productivity through expanding the use of

13

Table of Contents

distributors and resellers as distribution channels. Historically, virtually all of our international sales have been made through resellers, while domestically we have relied more heavily on a direct sales force. We intend to increase the use of distributors and resellers in our domestic market and reduce our reliance on direct sales.

Currently, over seventy-five percent of our revenue is generated through sales to our sales channel partners, which include distributors, resellers and system integrators. We increasingly depend upon these partners to generate sales opportunities and to independently manage the entire sales process. We provide our sales channel partners with specific programs to assist them in this process, but there can be no assurance that these programs will be effective or that our sales channel partners will be able to generate increasing revenues to us without significant additional investment on our part. To achieve profitability, we require our sales to grow without a commensurate increase in sales costs. Increasing sales through our sales channel partners is our primary strategy for achieving this. If we fail to create additional sales through our sales channel partners, our business will be seriously harmed.

If we are unable to introduce new products and services that achieve market acceptance quickly, we could lose existing and potential customers and our sales would decrease.

We need to develop and introduce new products and enhancements to existing products on a timely basis that keep pace with technological developments and emerging industry standards and address the increasingly sophisticated needs of our customers. We intend to extend the offerings under our product family in the future, both by introducing new products and by introducing enhancements to our existing products. However, we may experience difficulties in doing so, and our inability to timely and cost-effectively introduce new products and product enhancements, or the failure of these new products or enhancements to achieve market acceptance, could seriously harm our business. Furthermore, the reduction of research and development headcount resulting from the February 2002 restructuring and from attrition during fiscal 2003, may make this even more difficult. Life cycles of our products are difficult to predict because the market for our products is new and evolving and characterized by rapid technological change, frequent enhancements to existing products and new product introductions, changing customer needs and evolving industry standards. The introduction of competing products that employ new technologies and emerging industry standards could render our products and services obsolete and unmarketable or shorten the life cycles of our products and services. The emergence of new industry standards might require us to redesign our products. If our products are not in compliance with industry standards that become widespread, our customers and potential customers may not purchase our products.

We are entirely dependent on market acceptance of our secure proxy appliances and, as a result, lack of market acceptance of these products could cause our sales to fall.

To date, our prior caching products, secure proxy appliances and related services have accounted for all of our net sales. We anticipate that revenues from our current product family and services will continue to constitute substantially all of our net sales for the foreseeable future. As a result, a decline in the prices of, or demand for, our current product family and services, or their failure to achieve broad market acceptance, would seriously harm our business.

Undetected software or hardware errors could cause us to incur significant warranty and repair costs and negatively impact the market acceptance of our products.

Our products may contain undetected software or hardware errors. These errors may cause us to incur significant warranty and repair costs, divert the attention of our engineering personnel from our product development efforts and cause significant customer relations problems. The occurrence of these problems could result in the delay or loss of market acceptance of our products and would likely seriously harm our business. All of our products operate on our internally developed operating system. As a result, any error in the operating system will affect all of our products. We have experienced minor errors in the past in connection with new products. We expect that errors will be found from time to time in new or enhanced products after commencement of commercial shipments.

We are the target of Class Action and Patent Lawsuits, which could result in substantial costs and divert management attention and resources.

In June and July 2001, a series of putative securities class actions were filed against the firms that underwrote our initial public offering, us, and some of our officers and directors in the U.S. District Court for the Southern District of New York. These cases have been consolidated under the case captioned In re CacheFlow, Inc. Initial Public Offering Securities Litigation., Civil Action No. 1-01-CV-5143. An additional putative securities class action has been filed in the United States District Court for the Southern District of Florida. In the amended complaint that was filed, the plaintiffs apparently dropped us and individual officers and directors from the case. The complaints in the cases in New York and Florida generally allege that the underwriters obtained excessive and undisclosed commissions in connection with the allocation of shares of common stock in our initial public offering, and maintained artificially high market prices through tie-in arrangements which required customers to buy shares in the after-market at pre-determined prices. The complaints allege that we and our current and former officers and directors violated Sections 11 and 15 of the Securities Act of 1933, and Sections 10(b) (and Rule 10b-5 promulgated thereunder) and 20(a) of the Securities Act of 1934, by making material false and misleading statements in the prospectus incorporated in our Form S-1 registration statement filed with the Securities and Exchange Commission in November 1999. Plaintiffs seek an unspecified amount of damages on behalf of persons who purchased our stock between November 19, 1999 and December 6, 2000. In the cases pending in New York, the Court has appointed a lead plaintiff for the consolidated cases. On April 19, 2002 plaintiffs filed an amended complaint. Various plaintiffs have filed similar actions asserting virtually identical allegations against over 300 other public companies, their underwriters, and their officers and directors arising out of each company’s public offering. The lawsuits against us, along with these other related securities class actions currently pending in the Southern District of New York, have been assigned to Judge Shira A. Scheindlin for coordinated pretrial proceedings and collectively captioned In re Initial Public Offering Securities Litigation Civil Action No. 21-MC-92. Defendants in these cases have filed omnibus motions to dismiss on common pleading issues. Oral argument on these omnibus motions to dismiss was held on November 1, 2002. Our officers and directors have been dismissed without prejudice in this litigation. On February 19, 2003, the Court denied in part and granted in part the motion to dismiss filed on behalf of defendants, including us. The Court’s order did not dismiss any claims against us. As a result, discovery may now proceed.

A proposal has been made for the settlement and release of claims against the issuer defendants, including us, in exchange for a guaranteed recovery to be paid by the issuer defendants’ insurance carriers and an assignment of certain claims. The settlement is subject to a number of conditions, including approval of the proposed settling parties and the court.

If the settlement does not occur, and litigation against us continues, we believe we have meritorious defenses and intend to defend the case vigorously. We believe the outcome would not have a material adverse effect on our business, results of operations or financial condition. Securities class action litigation could result in substantial costs and divert our management’s attention and resources, which could seriously harm our business.

On August 1, 2001, Network Caching Technology L.L.C. filed suit against us and others in the U.S. District Court for the Northern District of California. The case is captioned Network Caching Technology, L.L.C., v. Novell, Inc., Volera, Inc., Akamai Technologies, Inc., CacheFlow, Inc., and Inktomi Corporation, civil Action No. CV-01-2079. The complaint alleges infringement of certain U.S. patents. The complaint seeks unspecified compensatory and treble damages and to permanently enjoin the defendants from infringing the patents in the future. We intend to defend against the allegations in the complaint vigorously and believe that the allegations in the lawsuit are without merit; however, if a judgment were issued against us, it could have a material adverse effect on our business, results of operations, or financial condition.

We may incur net losses or increased net losses if we are required to record additional significant accounting charges related to excess facilities that we are unable to sublease.

We have existing commitments to lease office space in Sunnyvale, California and Redmond, Washington in excess of our needs for the foreseeable future. The commercial real estate market in the San Francisco Bay Area and the Seattle Area has developed such a large excess inventory of office space that we believe we will be unable to sublease a substantial portion of our excess office space in the near future. Accordingly, in the fourth quarter of fiscal 2002, we recorded an excess facilities charge of $9.5 million, which represented the remaining lease commitments for vacant facilities, net of expected sublease income. As of April 30, 2003, $8.0 million of this accrued liability remains on the balance sheet. In July 2002, one of our facilities in Sunnyvale, California was subleased for the remainder of the lease term at a rental price that was consistent with our initial estimates. Our facility in Redmond, Washington was subleased in December 2002 for the remainder of the term of the original lease at a rental price consistent with our initial estimates. Due to its financial difficulties, our tenant in Sunnyvale, California surrendered the premises and vacated the property in January 2003. The facility in Sunnyvale, California is currently vacant and available for subleasing. As a result, we revised and increased our restructuring accruals for abandoned space by approximately $1.6 million during fiscal 2003 based on new market trend information provided by a commercial real estate broker. We may be required to record additional charges if our tenants default on their lease obligations and if current market conditions for the commercial real estate market remain the same or worsen.

If we fail to manage existing sales channels, our sales will not grow.

We evaluate and modify our distribution strategy from time to time to meet market requirements. Any direct channel new hire or new sales channel partner will require extensive training and typically take several months to achieve productivity. Competition for qualified sales personnel and sales channel partners is intense, and we might not be able to hire the kind and number of candidates we are targeting. If we fail to manage existing sales channels, our business will be seriously harmed.

Many of our sales channel partners do not have minimum purchase or resale requirements and carry products that are competitive with our products. These sales channel partners may not give a high priority to the marketing of our products or may not continue to carry our products. They may give a higher priority to other products, including the products of competitors. We may not retain any of our current sales channel partners or successfully recruit new sales channel partners. Events or occurrences of this nature could seriously harm our business.

Because we expect our sales to fluctuate and our costs are relatively fixed in the short term, our ability to forecast our quarterly operating results is limited, and if our quarterly operating results are below the expectations of analysts or investors, the market price of our common stock may decline.

Our net sales and operating results are likely to vary significantly from quarter to quarter. We believe that quarter-to-quarter comparisons of our operating results should not be relied upon as indicators of future performance. It is likely that in some future quarter or quarters, our operating results will be below the expectations of public market analysts or investors. When this occurs, the price of our common stock could decrease significantly. A number of factors are likely to cause variations in our net sales and operating results, including factors described elsewhere in this “Factors Affecting Future Operating Results” section.

We cannot reliably forecast our future quarterly sales for several reasons, including:

16

Table of Contents

A high percentage of our expenses, including those related to manufacturing overhead, technical support, research and development, sales and marketing, general and administrative functions and amortization of deferred compensation, are essentially fixed in the short term. As a result, if our net sales are less than forecasted, our quarterly operating results are likely to be seriously harmed and our stock price would likely further decline.

Our sales may not grow because our secure proxy appliances only protect Web based applications and content, and our target customers may not wish to purchase an additional network security device.

Our Web security appliances are specially designed to only secure Web based protocols such as http, https, ftp and streaming. While we believe that the majority of traffic traveling over the networks of our target customers is Web based, a significant amount of their network traffic is not. Our products do not protect non-Web protocols. Our target customers may not wish to purchase an additional security device that only handles network traffic that is Web protocol based. As a result, our target customers may not purchase our products and our business would be seriously harmed.

Our variable sales cycle makes it difficult to predict the timing of a sale or whether a sale will be made, which makes our quarterly operating results less predictable.

Because customers have differing views on the strategic importance of implementing secure proxy appliances, the time required to educate customers and sell our products can vary widely. As a result, the evaluation, testing, implementation and acceptance procedures undertaken by customers can vary, resulting in a variable sales cycle, which typically ranges from one to nine months. While our customers are evaluating our products and before they place an order with us, we may incur substantial sales and marketing expenses and expend significant management efforts. In addition, purchases of our products are frequently subject to unplanned processing and other delays, particularly with respect to larger customers for whom our products represent a very small percentage of their overall purchase activity. Large customers typically require approvals at a number of management levels within their organizations, and, therefore, frequently have longer sales cycles. The increasingly complex technological issues associated with secure proxy appliance solutions, combined with the macro-economic slowdown, contributed to longer sales cycles in fiscal years 2002 and 2003 and a resulting decline in our sequential quarterly sales through much of those periods. We may experience order deferrals or loss of sales as a result of lengthening sales cycles.

Our use of rolling forecasts could lead to excess or inadequate inventory, or result in cancellation charges or penalties, which could seriously harm our business.

We use rolling forecasts based on anticipated product orders, product order history and backlog to determine our materials requirements. Lead times for the parts and components that we order vary significantly and depend on factors such as the specific supplier, contract terms and demand for a component at a given time. If actual orders do not match our forecasts, as we experienced in the past, we may have excess or inadequate inventory of some materials and components or we could incur cancellation charges or penalties, which would increase our costs or prevent or delay product shipments and could seriously harm our business.

Because we depend on several third-party manufacturers to build portions of our products, we are susceptible to manufacturing delays and sudden price increases, which could prevent us from shipping customer orders on time, if at all, and may result in the loss of sales and customers.

We currently purchase from Mitac Corporation (“Mitac”) the base assemblies of most of our current products. Any Mitac manufacturing disruption could impair our ability to fulfill orders. We also rely on several other third-party manufacturers to build portions of our products. If we or our suppliers are unable to manage the

17

Table of Contents

relationships with these manufacturers effectively or if these manufacturers fail to meet our future requirements for timely delivery, our business would be seriously harmed. These manufacturers fulfill our supply requirements on the basis of individual purchase orders or agreements with us. Accordingly, these manufacturers are not obligated to continue to fulfill our supply requirements, and the prices we are charged for these components could be increased on short notice. Any interruption in the operations of any one of these manufacturers would adversely affect our ability to meet our scheduled product deliveries to our customers, which could cause the loss of existing or potential customers and would seriously harm our business. In addition, the products that these manufacturers build for us may not be sufficient in quality or in quantity to meet our needs. Our delivery requirements could be higher than the capacity of these manufacturers, which would likely result in manufacturing delays, which could result in lost sales and the loss of existing and potential customers. We cannot be certain that these manufacturers or any other manufacturer will be able to meet the technological or delivery requirements of our current products or any future products that we may develop and introduce. The inability of these manufacturers or any other of our contract manufacturers in the future to provide us with adequate supplies of high-quality products, or the loss of any of our contract manufacturers in the future, would cause a delay in our ability to fulfill customer orders while we attempt to obtain a replacement manufacturer. Delays associated with our attempting to replace or our inability to replace one of our manufacturers would seriously harm our business.

We have no long-term contracts or arrangements with any of our vendors that guarantee product availability, the continuation of particular payment terms or the extension of credit limits. We have experienced in the past, and may experience in the future, problems with our contract manufacturer, such as inferior quality, insufficient quantities and late delivery of product. To date, these problems have not materially adversely affected us. We may not be able to obtain additional volume purchase or manufacturing arrangements on terms that we consider acceptable, if at all. If we enter into a high-volume or long-term supply arrangement and subsequently decide that we cannot use the products or services provided for in the agreement, our business will be harmed. We cannot assure you that we can effectively manage our contract manufacturer or that this manufacturer will meet our future requirements for timely delivery of products of sufficient quality or quantity. Any of these difficulties could harm our relationships with customers and cause us to lose orders.

In the future, we may seek to use additional contract manufacturers. We may experience difficulty in locating and qualifying suitable manufacturing candidates capable of satisfying our product specifications or quantity requirements. Further, new third-party manufacturers may encounter difficulties in the manufacture of our products, resulting in product delivery delays.

Because some of the key components in our products come from limited sources of supply, we are susceptible to supply shortages or supply changes, which could disrupt or delay our scheduled product deliveries to our customers and may result in the loss of sales and customers.

We currently purchase several key parts and components used in the manufacture of our products from limited sources of supply. For example, we purchase custom power supplies and Intel hardware for use in all of our products. The introduction by Intel or others of new versions of their hardware, particularly if not anticipated by us, could require us to expend significant resources to incorporate this new hardware into our products. In addition, if Intel or others were to discontinue production of a necessary part or component, we would be required to expend significant resources in locating and integrating replacement parts or components from another vendor. Qualifying additional suppliers for limited source components can be time-consuming and expensive. Any of these events would be disruptive to us and could seriously harm our business. Further, financial or other difficulties faced by these suppliers or unanticipated demand for these parts or components could limit the availability of these parts or components. Any interruption or delay in the supply of any of these parts or components, or the inability to obtain these parts or components from alternate sources at acceptable prices and within a reasonable amount of time, would seriously harm our ability to meet our scheduled product deliveries to our customers.

If the protection of our proprietary technology is inadequate, our competitors may gain access to our technology, and our market share could decline.

We depend significantly on our ability to develop and maintain the proprietary aspects of our technology. To protect our proprietary technology, we rely primarily on a combination of contractual provisions, confidentiality procedures, trade secrets, copyright and trademark laws and patents. Despite our efforts to protect our proprietary rights, unauthorized parties may attempt to copy aspects of our products or obtain and use information that we regard as proprietary. Policing unauthorized use of our products is difficult. In addition, the laws of some foreign countries do not protect our proprietary rights to as great an extent as do the laws of the United States. Our means of protecting our proprietary rights may not be adequate and our competitors may independently develop similar technology, duplicate our products or design around patents that may be issued to us or our other intellectual property.

We presently have several issued patents, and pending United States patent applications. We cannot assure you that any U.S. patent will be issued from these applications. Even with issued patents, we cannot assure you that we will be able to detect any infringement or, if infringement is detected, that patents issued will be enforceable or that any damages awarded to us will be sufficient to adequately compensate us.

There can be no assurance or guarantee that any products, services or technologies that we are presently developing, or will develop in the future, will result in intellectual property that is protectable under law, whether in the United States or a foreign jurisdiction, that this intellectual property will produce competitive advantage for us or that the intellectual property of competitors will not restrict our freedom to operate, or put us at a competitive disadvantage.

We rely on technology that we license from third parties, including software that is integrated with internally developed software and used in our products to perform key functions. If we are unable to continue to license any of this software on commercially reasonable terms, we will face delays in releases of our software or will be required to drop this functionality from our software until equivalent technology can be identified, licensed or developed, and integrated into our current product. Any of these delays could seriously harm our business.

There has been a substantial amount of litigation in the technology industry regarding intellectual property rights and we are currently defending a suit, that alleges infringement of certain U.S. patents by us. (See Item 8, Note 13 “Litigation” of the consolidated financial statements included in this Annual Report on Form 10-K.) While we believe the case is without merit, it does show it is possible that third parties may claim that we, or our current or potential future products, infringe their intellectual property. We expect that companies in the Internet and networking industries will increasingly be subject to infringement claims as the number of products and competitors in our industry segment grows and the functionality of products in different industry segments overlaps. Any claims, with or without merit, could be time-consuming, result in costly litigation, cause product shipment delays or require us to enter into royalty or licensing agreements. Royalty or licensing agreements, if required, may not be available on terms acceptable to us or at all, which could seriously harm our business.

The legal environment in which we operate is uncertain and claims against us could cause our business to suffer.

Our products operate in part by storing material available on the Internet and making this material available to end users from our appliance. This creates the potential for claims to be made against us, either directly or through contractual indemnification provisions with customers, for defamation, negligence, copyright or trademark infringement, personal injury, invasion of privacy or other legal theories based on the nature, content or copying of these materials. It is also possible that if any information provided through any of our products contains errors, third parties could make claims against us for losses incurred in reliance on this information. Our insurance may not cover potential claims of this type or be adequate to protect us from all liability that may be imposed.

19

Table of Contents

We could be subject to product liability claims, which are time-consuming and costly to defend.

Our customers install our secure proxy appliance products directly into their network infrastructures. Any errors, defects or other performance problems with our products could negatively impact the networks of our customers or other Internet users, resulting in financial or other damages to these groups. These groups may then seek damages from us for their losses. If a claim were brought against us, we may not have sufficient protection from statutory limitations or license or contract terms with our customers, and any unfavorable judicial decisions could seriously harm our business. A product liability claim brought against us, even if not successful, would likely be time-consuming and costly. A product liability claim could seriously harm our business reputation.

We may not be able to generate a significant level of sales from the international markets in which we currently operate.

For the year ended April 30, 2003, sales to customers outside of the United States and Canada accounted for approximately 48% of our net sales as compared to 53% for our year ended April 30, 2002. We expect international customers to continue to account for a significant percentage of net sales in the future, but we may fail to maintain or increase international market demand for our products. The downsizing of our international operations as the result of our February 2001, August 2001 and February 2002 restructuring plans may further hinder our ability to increase our market concentration internationally. Also, because our international sales are currently denominated in United States dollars, an increase in the value of the United States dollar relative to foreign currencies could make our products more expensive and, therefore, potentially less competitive in international markets, and this would decrease our international sales. Our ability to generate international sales depends on our ability to maintain our international operations, including efficient use of existing resources and effective channel management, and recruit additional international resellers. To the extent we are unable to do so in a timely manner, our growth, if any, in international sales will be limited and our business could be seriously harmed.

Failure to comply with Nasdaq’s listing standards could result in our delisting by Nasdaq from the Nasdaq National Market and severely limit the ability to sell any of our common stock.

In order for our common stock to be listed on the Nasdaq National Market, we must continue to meet the Nasdaq National Market minimum listing requirements as set forth in the Nasdaq Marketplace Rules. The Rules require, among other things, that the bid price of our common stock not fall below $1 per share and that our stockholders’ equity not fall below $10 million. We currently meet all of the Nasdaq National Market listing requirements; however, in the future we may fail to do so. If we cannot meet the Nasdaq National Market minimum listing requirements, we may apply to transfer our common stock from the Nasdaq National Market to the Nasdaq SmallCap Market. However, there can be no assurance that we will be permitted to move to the Nasdaq SmallCap Market or that we will be able to meet the Nasdaq SmallCap Market listing requirements. Any delisting of our common stock from the Nasdaq National Market could severely impair our ability to raise additional capital and result in a significant decline in our common stock value.

Our stock price is volatile and, as a result, you may have difficulty evaluating the value of our stock, and the market price of our stock may decline.

Since our initial public offering in November 1999 through June 30, 2003, the closing market price of our common stock has fluctuated significantly, ranging from $2.25 to $823.45. The market price of our common stock may fluctuate significantly in response to the following factors:

20

Table of Contents

We are dependent upon key personnel and we must attract, assimilate and retain other highly qualified personnel in the future or our ability to execute our business strategy and generate sales could be harmed.

Our business could be seriously disrupted if we do not maintain the continued service of our senior management, research and development and sales personnel. We have experienced and may continue to experience transition in our management team. All of our employees are employed on an “at-will” basis. Our ability to conduct our business also depends on our continuing ability to attract, hire, train and retain a number of highly skilled managerial, technical, sales, marketing and customer support personnel. New hires frequently require extensive training before they achieve desired levels of productivity, so a high employee turnover rate could seriously impair our ability to operate and manage our business.

Failure to improve our infrastructure may adversely affect our business.

We must continue to implement and maintain a variety of operational, financial and management information systems, procedures and controls. The enactment of the Sarbanes-Oxley Act of 2002 and final and anticipated Securities and Exchange Commission regulations in 2002 and 2003 will require us to devote additional resources to our operational, financial and management information systems, procedures and controls to ensure our continued compliance with current and future laws and regulations. If we are unable to implement and maintain appropriate operational, financial and management information systems, procedures and controls, this could have a material adverse effect on our business, results of operations and financial condition.

We disclose or may disclose NON-GAAP financial information

We prepare and release quarterly unaudited financial statements prepared in accordance with generally accepted accounting principles (“GAAP”). We have in the past, and may in the future disclose and discuss certain non-GAAP financial information in the related earnings release and investor conference call. In the past this non-GAAP financial information excluded special charges, including the amortization of purchased intangibles, deferred stock compensation, in-process research and development expense, restructuring costs and excess facilities and asset impairment charges. We believe the disclosure of non-GAAP financial information helps investors more meaningfully evaluate the results of our ongoing operations. However, we urge investors to carefully review the GAAP financial information included as part of our Quarterly Reports on Form 10-Q, our Annual Reports on Form 10-K and our quarterly earnings releases, and to read the associated reconciliation between such GAAP financial information and non-GAAP financial information, if any, disclosed in our quarterly earnings releases and investor calls.

Because sales of our products are dependent on the increased use and widespread adoption of the Internet, if use of the Internet does not develop as we anticipate, our sales may not grow.

Sales of our products depend on the increased use and widespread adoption of the Internet. Our business would be seriously harmed if the use of the Internet does not increase as anticipated. The resolution of various issues concerning the Internet will likely affect the use and adoption of the Internet. These issues include security, reliability, capacity, congestion, cost, ease of access and quality of service. Even if these issues are resolved, if the market for Internet-related products and services fails to develop, or develops at a slower pace than anticipated, our business would be seriously harmed.

Our operations could be significantly hindered by the occurrence of a natural disaster or other catastrophic event.

Our operations are susceptible to outages due to fire, floods, power loss, telecommunications failures and other events beyond our control. In addition, a substantial portion of our facilities, including our headquarters, are located in Northern California, an area susceptible to earthquakes. We do not carry earthquake insurance for earthquake-related losses. Despite our implementation of network security measures, our servers are vulnerable to computer viruses, break-ins, and similar disruptions from unauthorized tampering with our computer systems. We may not carry sufficient business interruption insurance to compensate us for losses that may occur as a result of any of these events. Any such event could have a material adverse effect on our business, operating results and financial condition.

Item 2.    Properties

We lease approximately 53,000 square feet for our headquarters facility in Sunnyvale, California, under a lease that expires on August 31, 2005. In March 2001, we entered into a lease agreement to occupy 46,000 square feet for a research and development facility in Sunnyvale, California, beginning in the first quarter of our 2002 fiscal year. We also lease space for research and development in Redmond, Washington and Waterloo, Ontario, Canada. In addition, we lease space for sales and support in seven metropolitan areas in North America. We also lease space for sales and support in the following countries: France, Germany, Hong Kong, Japan, People’s Republic of China, Taiwan, United Arab Emirates and the United Kingdom.

In February 2002 we announced a restructuring plan that included closing down our research and development facilities in Redmond, Washington and Sunnyvale, California, and moving the research and development organization back into our headquarters facility in Sunnyvale, California. In July 2002, one of our facilities in Sunnyvale, California was subleased for the remainder of the lease term at a rental price that was consistent with our initial estimates. Our facility in Redmond, Washington was subleased in December 2002 for the remainder of the term of the original lease at a rental price consistent with our initial estimates. Due to its financial difficulties the tenant in Sunnyvale, California surrendered the premises and vacated the property in January 2003. The facility in Sunnyvale, California is currently vacant and available for subleasing

We believe that our existing facilities are adequate to meet our current requirements, and that suitable additional or substitute space will be available, if necessary.

Item 7.    Management’s Discussion and Analysis of Financial Condition and Results of Operations

The discussion in this Annual Report on Form 10-K contains forward-looking statements that involve risks and uncertainties. The statements contained in this Report that are not purely historical are forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, including statements on revenue expectations, product acceptance, product and sales development, operating results, and cash usage, as well as statements on our expectations, beliefs, intentions or strategies regarding the future. All forward-looking statements included in this document are based on information available to us on the date hereof. We assume no obligation to update any such forward-looking statements. Our actual results could differ materially from those indicated in such forward-looking statements. Factors that could cause or contribute to such differences include, but are not limited to, uncertainty in future operating results, uncertainty in the secure proxy appliance market, increased competition, downturn in macroeconomic conditions, inability to raise additional capital, inability to implement our distribution strategy, inability to introduce new products, increased litigation, failure to comply with Nasdaq’s listing standards, inability to attract and retain key employees, fluctuations in quarterly operating results, product concentration, technological changes, and other risks discussed in this item under the heading “Factors Affecting Future Operating Results” and the risks discussed in our other recent Securities and Exchange Commission filings.

The following table sets forth consolidated statements of operations data as a percentage of net sales for the periods indicated:

Table of Contents

Overview

We have incurred net losses in each quarter since inception. As of April 30, 2003, we had an accumulated deficit of $865.1 million. We incurred net losses of $15.9 million, $247.0 million and $519.1 million for the years ended April 30, 2003, 2002 and 2001, respectively. These losses resulted from charges related to the impairment of certain intangible and long-lived assets, the amortization of deferred stock compensation and goodwill and significant costs incurred in the development and sale of our products and services. Additionally, we experienced a significant decline in the demand for our products during the years ended April 30, 2002 and 2003, which resulted in declining revenues during such years. We believe these declines in revenues resulted from the weakening global economy and a corresponding reduction in information technology spending. Unless there are positive changes in current macroeconomic conditions, we expect that the lowered levels of demand experienced in fiscal 2002 and 2003 will continue throughout fiscal 2004. As a result, we expect to incur additional operating losses and continued negative cash flows from operations through at least fiscal 2004. We have reduced our operating expenses to accommodate lower revenues, and we believe that the losses in fiscal 2004 will be substantially lower than prior years. Our limited operating history makes the prediction of future operating results difficult. We believe that period-to-period comparisons of our operating results should not be relied upon as a prediction of future performance. Our prospects must be considered in light of the risks, expenses and difficulties encountered by companies at an early stage of development, particularly companies in new and rapidly evolving markets. We may not be successful in addressing these risks and difficulties.

Critical Accounting Policies

Our discussion and analysis of financial condition and results of operations is based upon our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of our consolidated financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. We evaluate, on an ongoing basis, our estimates and judgments, including those related to sales returns, bad debts, warranty costs, excess inventory and purchase commitments, investments, intangible assets, lease losses and restructuring accruals, income taxes and contingencies based on historical experience and other factors that we believe to be reasonable under the circumstances. However, actual results may differ from these estimates under different assumptions or conditions.

We have discussed the development and selection of critical accounting policies and estimates with our audit committee. We believe the accounting policies described below, among others, are the ones that most frequently require us to make estimates and judgments, and therefore are critical to the understanding of our results of operations:

Revenue Recognition and Related Allowances.    We recognize product revenue upon shipment, assuming that evidence of an arrangement between the customer and us exists, the fee to the customer is fixed or determinable and collectability of the sales price is probable, unless the Company has future obligations for installation or must obtain customer acceptance, in which case revenue is deferred until these obligations are met. Revenues related to shipments to our distributors who have certain stock rotation rights are deferred until a point of sale report is received from the distributor confirming that our products have been sold to a reseller or an end user. Maintenance contract revenue is initially deferred and recognized ratably over the life of the contract. Probability of collection is assessed on a customer by customer basis. Our customers are subjected to a credit

26

Table of Contents

review process that evaluates the customers’ financial position and ability to pay for our products and services. If it is determined from the outset of an arrangement that collection is not probable based upon our review process, revenue is recognized upon cash receipt. During the course of fiscal 2003 and 2002, we deferred certain revenue based on this criteria and revenue from certain customers was recognized based upon cash receipts.

We also perform ongoing credit evaluations of our customers’ financial condition and maintain an allowance for estimated credit losses. We analyze accounts receivable and historical bad debts, customer concentrations, customer solvency, current economic and geographic trends and changes in customer payment terms and practices when evaluating the adequacy of such allowance. If the financial condition of our customers deteriorates, resulting in an impairment of their ability to make payments, additional allowances may be required.

Warranty Reserves.    We accrue for warranty expenses at the time revenue is recognized and maintain a warranty accrual for estimated future warranty obligations based upon the relationship between historical and anticipated costs and sales volumes. If actual warranty expenses are greater than those projected, additional reserves and other charges against earnings may be required. If actual warranty expenses are less than projected, prior reserves could be reduced providing a positive impact on our reported results. See Item 8, Note 2 “Summary of Significant Accounting Policies—Guarantees” of the consolidated financial statements included in this Annual Report on Form 10-K for further discussion.

Inventory and Related Reserves.    We state our inventories at the lower of cost or market. In addition, we evaluate our ending inventories for estimated excess quantities and obsolescence. In assessing the ultimate recoverability of inventories, we are required to make estimates regarding future customer demand and market conditions. Although we strive to ensure the accuracy of our forecasts of future product demand, any significant unanticipated changes in demand or technological developments could have a significant impact on the value of our inventory and commitments, and our reported results. If actual market conditions are less favorable than those projected, additional reserves and other charges against earnings may be required. If actual market conditions are more favorable than projected, prior reserves for excess and obsolete inventories could be reduced providing a positive impact on our reported results. See Item 8, Note 2 “Summary of Significant Accounting Policies—Inventories” of the consolidated financial statements included in this Annual Report on Form 10-K for further discussion.

Restructuring Liabilities.    During the years ended April 30, 2002 and 2001, as a result of continuing unfavorable economic conditions and a reduction in customer IT spending rates, we implemented restructuring programs, which included reductions in workforce and a consolidation of facilities. The restructuring liabilities recorded in our consolidated financial statements included in this Annual Report on Form 10-K include various assumptions such as the time period over which the facilities will be vacant, expected sublease terms, and expected sublease rates. These estimates are reviewed and revised periodically and may result in a substantial change to restructuring expense should different conditions prevail than were anticipated in original management estimates. These conditions may include, but are not limited to, changes in estimated time to sublease the facilities, sublease terms, sublease rates, and lease termination. In this regard, due to its financial difficulties, the tenant in one of our Sunnyvale, California facilities surrendered the premises and vacated the property in January 2003. This facility is currently vacant and available for subleasing. As a result, we revised and increased our estimated restructuring liabilities for abandoned space during fiscal 2003 based on new market trend information provided by a commercial real estate broker. Should operating lease rental rates decline, should it take longer than expected to find a suitable tenant to sublease our facility, or should our other tenant terminate its sublease, adjustments to the restructuring accruals may be necessary in future periods based upon the then-current actual events and circumstances. See Item 8, Note 6 “Restructuring Charges” of the consolidated financial statements included in this Annual Report on Form 10-K for further discussion.

Contingencies.    Management’s current estimated range of liability related to pending litigation is based on claims for which it is probable that a liability has been incurred and our management can estimate the amount and range of loss. Because of the uncertainties related to both the determination of the probability of an

27

Table of Contents

unfavorable outcome and the amount and range of loss in the event of an unfavorable outcome, management is unable to make a reasonable estimate of the liability that could result from the remaining pending litigation. As additional information becomes available, we will assess the probability and the potential liability related to our pending litigation and revise our estimates, if necessary. Such revisions in our estimates of potential liability could materially impact our results of operations and financial position. See Item 8, Note 13 “Litigation” of the consolidated financial statements included in this Annual Report on Form 10-K for further discussion.

Results of Operations

Net Sales.    Net sales decreased to $45.7 million for the fiscal year ended April 30, 2003 from $55.6 million in fiscal 2002, and from $97.7 million in fiscal 2001. These decreases in fiscal 2003 and 2002 were primarily attributable to fewer unit sales and a purchasing trend towards our lower-end systems, which have lower average sales prices than our higher-end systems, partially offset by increased service and other product revenue.

As a result of our focus on increasing the use of indirect distribution channels, one of our distributors accounted for 19.0% of our net sales during the year ended April 30, 2003. No customer accounted for more than 10% of our net sales during the years ended April 30, 2002 and 2001.

Net sales for the year ended April 30, 2003 were $23.8 million from the United States, or 52% of net sales, $12.8 million from Europe, or 28% of net sales, and $9.1 million from Asia, or 20% of net sales. Net sales for the year ended April 30, 2002 were $26.3 million from the United States, or 47% of net sales, $12.3 million from Europe, or 22% of net sales, and $17.0 million from Asia, or 31% of net sales. Net sales for the year ended April 30, 2001 were $40.0 million from the United States., or 41% of net sales, $21.7 million from Europe, or 22% of net sales, and $36.0 million from Asia, or 37% of net sales.

Net sales for the year ended April 30, 2003 were $30.3 million from our ProxySG products, or 66% of net sales, $5.5 million from our Legacy products, or 12% of net sales, and $9.9 million from Services, or 22% of net sales. Net sales for the year ended April 30, 2002 were $28.3 million from our ProxySG products, or 51% of net sales, $19.4 million from our Legacy products, or 35% of net sales, and $7.9 million from Services, or 14% of net sales. Unless macroeconomic conditions improve sooner than anticipated, our visibility of the near-term demand for our products is limited; however, we currently anticipate that we may see modest net sales growth in the next several quarters.

Gross Profit.    Gross profit decreased to $28.7 million and $29.7 million in fiscal 2003 and 2002, respectively, from $49.6 million in fiscal 2001. These decreases in fiscal 2003 and 2002 were primarily due to lower sales volumes, as discussed above, and offset by increases in our maintenance revenue, which has relatively fixed expenses. Gross profit as a percentage of net sales increased to 62.9% and 53.4% in fiscal 2003 and 2002, respectively, from 50.7% in fiscal 2001. The increase in gross profit as a percentage of sales in fiscal 2003 was the result of (i) lower fixed manufacturing and support costs in fiscal 2003 as a result of restructuring programs initiated in prior fiscal years, (ii) a $0.2 million reduction in our warranty reserves as a result of the reliability of our new products, specifically our ProxySG 800 series product line, who’s reliability exceeded our initial expectations based on our experience with prior products and (iii) a $0.3 million reduction in our inventory reserves because customer demand for our ProxySG 6000 series products exceeded the initial estimates we made when we established reserves for excess and obsolete inventory of this product line.

The increase in gross profit as a percentage of sales in fiscal 2002 was the result of a decrease in cost of goods sold due to lower direct material costs and reduced fixed manufacturing and support costs, offset by a $1.4 million increase in our inventory reserves as a result of the changes in market demand which began in fiscal 2001, as discussed further below, and continued into fiscal 2002.

During fiscal 2001, we increased our inventory reserves by $3.9 million because inventories were built up in anticipation of projected sales volumes that never materialized as a result of the sharp deterioration in

28

Table of Contents

macroeconomic conditions that caused customers to defer or delay capital expenditures on information technology.

Our gross profit has been and will continue to be affected by a variety of factors, including competition, fluctuations in demand for our products, the timing and size of customer orders and product implementations, the mix of direct and indirect sales, the mix and average selling prices of products, new product introductions and enhancements, component costs, manufacturing costs and product configuration. If actual orders do not match our forecasts, as we have experienced in the past, we may have excess or inadequate inventory of some materials and components or we could incur cancellation charges or penalties, which would increase our costs or prevent or delay product shipments and could seriously harm our business.

Research and Development.    Research and development expenses consist primarily of salaries and benefits and prototype and testing equipment costs. Research and development expenses decreased to $11.4 million in fiscal 2003 from $35.1 million in fiscal 2002 and $27.7 million in fiscal 2001. The decrease in research and development expenses from fiscal 2002 to fiscal 2003 in absolute dollars is primarily attributable to a decrease in staffing. Additionally, in fiscal 2003, we received $0.6 million in tax refunds for fiscal 2000 and 2001 scientific research and experimental development expenditures related to our research and development office in Canada, which were recorded as a reduction of research and development expense. The increase in research and development expenses from fiscal 2001 to fiscal 2002 in absolute dollars was primarily attributable to higher staffing levels throughout 2002 until the reduction in headcount in the fourth quarter of fiscal 2002, as discussed further below. Research and development headcount decreased to 62 at April 30, 2003 from 84 at April 30, 2002, and from 204 at April 30, 2001. The decrease in research and development headcount at April 30, 2003 and 2002, is a result of the restructuring plan initiated in the fourth quarter of fiscal 2002, as discussed further below.

As a percentage of net sales, research and development expenses decreased to 24.9% in fiscal 2003 from 63.1% in fiscal 2002 and 28.3% in fiscal 2001. The decrease in research and development expenses as a percentage of net sales in fiscal 2003 occurred despite lower revenue due to the significant reduction in research and development headcount in the fourth quarter of fiscal 2002, as discussed further below. The increase in research and development expenses as a percentage of net sales from fiscal year 2001 to 2002 occurred because we continued to invest significantly in research and development projects during much of fiscal 2002, while revenues were declining. In the fourth quarter of fiscal 2002, we significantly reduced research and development headcount in light of continued lower revenues. Should growth in demand for our products resume, and after we realize potential efficiencies within our research and development organization, we expect to increase our research and development expenses in absolute dollars and increase headcount within the research and development organization to provide for the development of new products. However, should sales decline further in future periods, we may implement additional cost reduction programs to further reduce our research and development expenses.

Sales and Marketing.    Sales and marketing expenses consist primarily of salaries and benefits, commissions, advertising and promotional expenses. Sales and marketing expenses decreased to $25.2 million in fiscal 2003 from $30.0 million in fiscal 2002 and $61.5 million in fiscal 2001. These decreases in sales and marketing expenses in absolute dollars were related to reductions in headcount. Sales and marketing headcount decreased to 81 at April 30, 2003 from 98 at April 30, 2002 and 211 at April 30, 2001. As a percentage of net sales, sales and marketing expenses increased to 55.2% in fiscal 2003 from 54.0% in fiscal 2002, which was a decrease from 62.9% in fiscal 2001. The increase in sales and marketing expense as a percentage of net sales in fiscal 2003 was not significant. The decrease in sales and marketing expense as a percentage of net sales in fiscal 2002 occurred despite lower revenue due to our cost reduction programs. Should growth in demand for our products resume, and after we realize potential efficiencies within our sales and marketing organization, we expect to increase our sales and marketing expenses in absolute dollars in an effort to expand domestic and international markets, introduce new products and establish and expand new distribution channels. However, should sales decline further in future periods, we may implement additional cost reduction programs to further reduce our sales and marketing expenses.

General and Administrative.    General and administrative expenses decreased to $4.8 million in fiscal 2003 from $9.5 million in fiscal 2002 and $10.5 million in fiscal 2001. These decreases in general and administrative expenses in absolute dollars during fiscal 2003 and 2002 were related to decreased headcount. General and administrative headcount decreased to 25 at April 30, 2003 from 27 at April 30, 2002, and from 55 at April 30, 2001. As a percentage of net sales, general and administrative expenses decreased to 10.5% in fiscal 2003 from 17.1% in fiscal 2002, which was an increase from 10.8% in fiscal 2001. The decrease in general and administrative expenses as a percentage of net sales in fiscal 2003 was a result of the restructuring plan implemented in the fourth quarter of fiscal 2002. The increase in general and administrative expenses as a percentage of net sales in fiscal 2002 was a result of the decline in sales experienced in fiscal 2002 compared to fiscal 2001 and an increase in the provision for bad debt expense of $1.0 million in fiscal 2002. Should growth in demand for our products resume, and after we have realized potential efficiencies within our current general and administrative organization, we expect to increase general and administrative expenses in absolute dollars and increase headcount to manage expanding operations and facilities. However, should sales decline further in future periods, we may implement additional cost reduction programs to further reduce our general and administrative expenses.

Stock Compensation.    Stock compensation expense decreased to $2.1 million in fiscal 2003 from $19.5 million in fiscal 2002 and $69.2 million in fiscal 2001. Stock compensation expense reflects the amortization of non-cash deferred stock compensation, as well as charges associated with stock options and warrants granted to non-employees for services and modifications to stock-based awards for certain departed employees. Stock compensation expense decreased in fiscal 2003 compared to fiscal 2002 and 2001 as a result of decreased headcount and decreased amortization of deferred stock compensation for remaining employees. Our policy is to amortize such deferred stock compensation using a graded method. Graded amortization methods result in greater amortization in earlier years, and most of our deferred stock compensation was recorded in connection with our November 1999 initial public offering, certain below-market option grants in fiscal 2001 and unvested options assumed in our December 2000 acquisition of Entera. In addition, the fiscal 2001 expense includes a deferred stock compensation charge of $28.1 million in connection with the accelerated vesting of certain unvested stock options held by the former chairman of our board of directors. Based on the options granted through April 30, 2003, we have a remaining balance of $0.6 million in deferred stock compensation. This amount will be fully amortized by fiscal 2005.

In the fourth quarter of fiscal 2003, we discovered that we had overstated our non-cash stock compensation expense for the quarters ended July 31, 2002, October 31, 2002 and January 31, 2003, resulting in a net loss for those periods that was slightly lower than previously reported. The stock compensation expense for these periods was lower than previously reported by approximately $0.2 million in the third quarter of fiscal 2003, $0.1 million in the second quarter of fiscal 2003 and $0.5 million in the first quarter of fiscal 2003. This overstatement related to non-cash stock compensation expenses for certain employees who separated from us prior to being fully vested in their stock options. We amortize deferred stock compensation using a graded method, and we have not adjusted compensation expense related to separated employees in the period of separation to the amount that was contractually vested as of the separation date. After adjusting the results in these prior quarters to correctly reflect the lower expense, our net loss was reduced to $4.1 million, or $0.47 per share, for the third quarter of fiscal 2003, $5.1 million, or $0.58 per share, for the second quarter of fiscal 2003 and $5.4 million, or $0.62 per share, for the first quarter of fiscal 2003. We also discovered that we had overstated our stock compensation expense for the years ended April 30, 2002 and 2001 by amounts that were immaterial to the consolidated financial results previously reported for those periods.

Goodwill Amortization.    There was no goodwill amortization for the company in fiscal 2003, a decrease from $29.5 million in fiscal 2002 and $99.0 million in fiscal 2001. The decrease in 2002 was primarily attributable to the cumulative $407.0 million asset impairment charges during fiscal 2002 and 2001 that ultimately decreased our entire goodwill balance to zero. Furthermore, purchase accounting for the acquisition of Entera was completed during fiscal 2002, resulting in a $0.7 million reduction of goodwill. For additional discussion regarding goodwill impairment charges, refer to the “Impairment of Assets” section below.

Table of Contents

Acquired In-Process Research and Development.    We recorded a non-recurring, non-cash $32.2 million charge in fiscal 2001 for the value of in-process research and development acquired in the Entera transaction, which relates to in-process research and development that had not yet reached technological feasibility and had no future use in our development activities. No such charges were recorded in fiscal years 2002 or 2003.

There were two projects included in the in-process research and development for Entera. The efforts required to complete the acquired in-process research and development included the completion of all planning, designing and testing activities that are necessary to establish that the product can be produced to meet its design requirements, including functions, features and technical performance requirements. The value of the acquired in-process research and development was computed using a discounted cash flow analysis rate of 50% on the anticipated income stream of the related product revenues. The discounted cash flow analysis was based on our forecast of future revenues, cost of revenues and operating expenses related to the products and technologies purchased from Entera. The calculation of value was then adjusted to reflect only the value creation efforts of Entera prior to the close of the acquisition. At the time of the acquisition, the products were approximately 32% and 50% complete, respectively, with approximately $10.9 million and $0.9 million in estimated costs remaining, respectively. The majority of these costs were incurred by the end of fiscal 2002. The acquired in-process research and development was expensed in the period the transaction was consummated.

Restructuring Charges.    As discussed further under “Reorganization Plans” below, and in Item 8, Note 6 “Restructuring Charges” of the consolidated financial statements included in this Annual Report on Form 10-K, we recorded charges of approximately $15.5 million and $1.9 million in fiscal 2002 and fiscal 2001, respectively, related to facilities closure costs, lease abandonment costs, certain employee severance costs and contract termination costs. We revised certain of our estimates and recorded an additional $1.3 million of restructuring charges in fiscal 2003.

Impairment of Assets.    As discussed further under “Asset Impairment” below, and in Item 8, Note 6 “Impairment of Assets” of the consolidated financial statements included in this Annual Report on Form 10-K, in fiscal 2002 we performed impairment assessments of our long-lived assets and determined that enterprise-level goodwill associated with the SpringBank and Entera acquisitions was impaired. As a result, impairment charges of $134.1 million and $272.2 million were recorded in fiscal 2002 and 2001, respectively, to write our enterprise-level goodwill net book value down to zero as of April 30, 2002. Additionally, we recorded write-downs related to certain leasehold improvements of $4.7 million and $0.7 million in fiscal 2002 and 2001, respectively. The leasehold improvement write-downs related to two research and development facilities, which were closed and/or relocated in fiscal 2002 and 2001 in connection with our restructuring and reorganization activities. We recorded no write-downs of long-lived assets during the year ended April 30, 2003.

Interest and Other Income (Expense).    Interest income decreased to $0.6 million in fiscal 2003 from $2.1 million in fiscal 2002 and $6.7 million in fiscal 2001. These decreases were primarily attributable to lower cash balances and lower interest rates earned on our cash equivalents and short-term investments.

Provision for Income Taxes.    The provision for income taxes, which is composed entirely of foreign corporate income taxes, decreased to $0.3 million in fiscal 2003 from $0.5 million in fiscal 2002, which was an increase from $0.3 million in fiscal 2001. The foreign corporate income taxes are a function of our international expansion and the establishment of branches and subsidiaries in various jurisdictions. The provision for income taxes is based on income taxes on profits the foreign operations generated for services provided to us.

We have incurred losses from inception through fiscal 2003. We believe that, based on the history of such losses and other factors, it is more likely than not that we will not be able to realize our deferred tax assets. Therefore, a full valuation allowance has been recorded at April 30, 2003 and 2002. The valuation allowance increased (decreased) by ($10.4 million), $59.8 million and $43.7 million during fiscal 2003, 2002 and 2001, respectively.

As of April 30, 2003, we had net operating loss carryforwards for federal income tax purposes of approximately $241.9 million, which begin to expire in 2011, if not utilized. We also had net operating loss carryforwards for state income tax purposes of approximately $97.5 million, which will begin to expire in fiscal year 2006, if not utilized. We also had federal and California research and other tax credit carryforwards of approximately $3.8 million, which will begin to expire in fiscal 2012, if not utilized.

Utilization of our net operating loss and credit carryforwards may be subject to substantial annual limitations due to the ownership change limitations provided by the Internal Revenue Code and similar state provisions. Such annual limitations could result in the expiration of the net operating loss and tax credit carryforwards before utilization. The events that may cause ownership changes in our net operating loss include, but are not limited to, a cumulative stock ownership change of greater than 50% over a three year period.

Acquisitions

SpringBank Networks, Inc.—On June 5, 2000, we acquired all of the outstanding capital stock of SpringBank Networks, Inc. (“SpringBank”), a privately held company organized to develop content management technologies. The acquisition was accounted for under the purchase method of accounting and, accordingly, the purchase price was allocated to the assets acquired and liabilities assumed based on their estimated fair values on the acquisition date. Since June 5, 2000, the results of operations of SpringBank have been included in our consolidated statements of operations. Purchase consideration totaled approximately $177.0 million and included approximately 550,000 shares of our common stock, approximately $7.0 million of assumed liabilities and approximately $2.0 million in transaction costs. The entire $177.0 million purchase price was allocated to goodwill. For further discussion regarding goodwill, refer to the “Asset Impairment” section below.

Entera, Inc.—On December 15, 2000, we completed the acquisition of Entera, Inc. (“Entera”), a company that develops standards-based streaming content distribution and management technologies, in a stock-for-stock merger transaction accounted for as a purchase. The purchase consideration was approximately $411.9 million consisting of approximately 680,000 shares of our common stock with a fair value of approximately $370.8 million, the assumption of approximately 80,000 outstanding stock options with a fair value of approximately $40.0 million, and approximately $1.1 million in transaction costs. The excess of the purchase price over the fair value of the net assets acquired was valued at $409.1 million. Of this excess, $359.3 million was allocated to goodwill, $17.6 million was allocated to deferred compensation, and $32.2 million was allocated to in-process research and development. For further discussion regarding goodwill, refer to the “Asset Impairment” section below.

Stock Compensation

We recorded deferred stock compensation of approximately $17.4 million for the year ended April 30, 2001. We did not record any deferred stock compensation in fiscal 2003 and 2002. Our deferred stock compensation balance generally represents the difference between the exercise price and the market price of the underlying stock on the date stock options are granted to employees. However, we have also completed other stock-based transactions that impact deferred stock compensation, such as acquisitions in which the outstanding options of the acquired entity are assumed. Deferred stock compensation is amortized to stock compensation expense over the option vesting period, generally two to four years, or recognized immediately if there is no vesting period. In addition to amortization of deferred stock compensation, stock compensation expense includes charges associated with stock options and warrants granted to non-employees for services and modifications to stock-based awards for certain departed employees. We recorded stock compensation expense of approximately $2.1 million, $19.5 million and $69.2 million for the years ended April 30, 2003, 2002 and 2001. We may record additional deferred stock compensation and/or stock compensation expense in the future if management decides to grant below-market stock options, assume outstanding options in any future acquisitions, modify outstanding stock awards subsequent to their date of grant, or enter into other transactions that may require the recognition of additional compensation. We expect stock compensation expense, which is primarily attributable to amortization of deferred stock compensation, to impact our reported results through fiscal 2005.

Reorganization Plans

In February 2002, our Board of Directors approved a restructuring program to significantly reduce our operating expenses and further align our organization with market conditions, future revenue expectations and our planned future product direction at that time. In connection with this restructuring plan, we implemented a reduction in workforce of approximately 200 employees. We accrued approximately $12.9 million in the fourth quarter ended April 30, 2002, comprised of employee severance costs of approximately $2.7 million, facilities closure and lease abandonment costs of approximately $9.5 million and contract termination costs of approximately $0.7 million. All employees were notified of their termination prior to April 30, 2002. Estimates related to sublease costs and income were based on assumptions regarding sublease rates and the time required to locate sub-lessees, which were derived from market trend information provided by a commercial real estate broker. These estimates are reviewed on a periodic basis and to the extent that these assumptions materially change due to changes in the market, the ultimate restructuring expense for the abandoned facility will be adjusted. In July 2002, one of our facilities in Sunnyvale, California was subleased for the remainder of the lease term at a rental price that was consistent with our initial estimates. Our facility in Redmond, Washington was subleased in December 2002 for the remainder of the term of the original lease at a rental price consistent with our initial estimates. Due to its financial difficulties, the tenant in Sunnyvale, California surrendered the premises and vacated the property in January 2003. The facility in Sunnyvale, California is currently vacant and available for subleasing. As a result, we revised and increased our estimated restructuring accruals for abandoned space by $1.6 million during fiscal 2003 based on new market trend information provided by a commercial real estate broker. We also reduced our estimates for contract termination costs by $0.3 million during fiscal 2003, as we were able to negotiate lower settlement amounts than originally estimated. As of April 30, 2003, substantially all severance costs related to domestic and international employees had been paid, and approximately $8.0 million remained accrued for lease abandonment and contract termination costs. The lease abandonment costs will be paid over the respective lease terms through 2007.

In August 2001, our Board of Directors approved a restructuring program in response to the continued economic slowdown that negatively impacted first quarter of fiscal 2002 demand for our products as potential customers deferred spending on Internet and intranet infrastructure. In order to streamline our cost structure and better position us for planned growth, we implemented a reduction in workforce of approximately 80 positions. We incurred $2.6 million in restructuring costs in the quarter ended October 31, 2001, which included employee severance costs of approximately $1.7 million and certain contract termination costs of approximately $0.9 million. As of April 30, 2003, these severance payments and contract termination payments were completed.

In February 2001, we announced a reorganization plan and incurred $1.9 million in reorganization costs in the quarter ended April 30, 2001 to complete this effort, which primarily included employee severance costs of approximately $1.3 million to reduce our workforce by 52 employees and certain contract termination costs of approximately $0.6 million. This plan was instituted in response to an unanticipated economic slowdown that negatively impacted third and fourth quarter fiscal 2001 demand for our products, as potential customers deferred spending on Internet and intranet infrastructure. The reorganization plan was designed to more closely align spending with our sales projections. As of April 30, 2003, these severance payments and contract termination payments were completed.

Changes in our restructuring accruals are as follows (in thousands):

We cannot assure you that our most recent restructuring program will achieve all of the expense reductions and other benefits that we anticipate. In addition, anticipated savings from the reduced headcount or facility consolidations have been, and may in the future be, mitigated by changes in circumstances or subsequent increases in headcount and facilities related to our operating requirements. See Item 8, Note 6 “Restructuring Charges” of the consolidated financial statements included in this Annual Report on Form 10-K for further discussion.

Asset Impairment

In fiscal 2002 and 2001, we determined that certain enterprise level goodwill recorded in connection with our SpringBank and Entera acquisitions was not fully recoverable. Our impairment assessments were performed because (i) our stock price had declined significantly and the net book value of our assets significantly exceeded our market capitalization, and (ii) industry growth rates had declined significantly.

The overall decline in industry growth rates indicated that this trend might continue for an indefinite period. As a result, we recorded impairment charges of $134.1 million and $272.2 million in fiscal 2002 and 2001, respectively, to reduce goodwill to its estimated fair value based on the market value method. The estimated of fair value was based upon our average market capitalization, which was calculated using our average closing stock price surrounding each respective measurement date. As of April 30, 2002, goodwill was fully written-off. Additionally, we recorded write-downs related primarily to certain leasehold improvements of $4.7 million and $0.7 million in fiscal 2002 and 2001, respectively. The leasehold improvement write-downs related to two research and development facilities, which were closed and/or relocated in fiscal 2002 and 2001 in connection with our restructuring and reorganization activities. We recorded no write-downs of long-lived assets during the year ended April 30, 2003.

Liquidity and Capital Resources

From our inception in March 1996, we have financed our operations and capital expenditures through private sales of preferred stock, bank loans, equipment leases, and an initial public offering of our common stock. As of April 30, 2003, we had $12.8 million in cash and cash equivalents, $10.5 million in short-term investments, $2.0 million in restricted investments and $16.9 million in working capital.

Net cash used in our operating activities was $16.3 million in fiscal 2003, $40.8 million in fiscal 2002 and $54.1 million in fiscal 2001. We used cash primarily to fund our net losses from operations. We implemented a strategic restructuring plan in the fourth quarter of our fiscal 2002 with the goal of reducing our net cash used in

34

Table of Contents

operating activities beginning with the first quarter of fiscal 2003, and we continued to make reductions in fiscal 2003 which have further lowered the cash used in our operating activities. Cash used in operating activities in fiscal 2003 includes $4.1 million of payments against accrued restructuring liabilities related to terminated and vacated facilities leases. We expect to make payments of approximately $2.9 million against our accrued restructuring liabilities over the next 12 months.

Net cash provided by (used in) investing activities was $16.2 million in fiscal 2003, ($2.9 million) in fiscal 2002 and $3.5 million in fiscal 2001. Net cash provided by investing activities in fiscal 2003 was primarily due to sales of short-term investments of approximately $16.9 million, partially offset by purchases of property and equipment of approximately $0.7 million. Net cash used in investing activities in fiscal 2002 was primarily attributable to purchases of property and equipment. Net cash provided by investing activities in fiscal 2001 was primarily due to cash acquired in business acquisitions of approximately $7.8 million and sales of short-term investments of approximately $5.4 million, offset by purchases of property and equipment of approximately $9.8 million. In the future, we expect that any cash in excess of current requirements will continue to be invested in short-term investment grade, interest-bearing securities. During the years ended April 30, 2003, 2002 and 2001, our capital expenditures consisted primarily of purchases of computer equipment and software, furniture and leasehold improvements.

Net cash provided by financing activities was $0.4 million in fiscal 2003, $0.9 million in fiscal 2002 and $14.5 million in fiscal 2001. The net cash provided by our financing activities during fiscal 2003, 2002 and 2001 was primarily due to proceeds received from the issuance of common stock of $0.3 million, $1.0 million and $15.0 million, respectively.

Our contractual operating lease commitments as of April 30, 2003 for the next five years were as follows:

We lease certain equipment and office facilities under various noncancelable operating leases that expire at various dates through 2008. The facility leases generally require us to pay operating costs, including property taxes, insurance and maintenance, and contain scheduled rent increases and certain other rent escalation clauses. Rent expense is reflected in our consolidated financial statements on a straight-line basis over the terms of the respective leases. As of April 30, 2003, we did not have any other significant contractual obligations or commercial commitments.

As of April 30, 2003, we did not have any relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities, which would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. Further, we have not guaranteed any obligations of unconsolidated entities, nor do we have any commitment or intent to provide additional funding to any such entities. As such, we are not materially exposed to any market, credit, liquidity or financing risk that could arise if we had engaged in such relationships.

We have suffered recurring losses from operations and currently project that such losses will continue into fiscal 2004. Our current business plan for 2004 reflects continued initiatives to increase revenue, reduce overhead, and realize the benefit of reductions in employee headcount and occupancy costs, and such business

35

Table of Contents

plan projects that the amount of our quarterly net loss will decline from quarter to quarter with net income projected to begin in late fiscal 2004. As a result, our cash, cash equivalent and short-term investment balances as of April 30, 2003 are projected to be sufficient to fund the excess of expenses over revenue and allow us to continue as a going concern at least through April 30, 2004. Furthermore, in our review of our operating requirements, we determined that, even with a reduction of fiscal 2004 revenues in excess of 50% from fiscal 2003, we would still have sufficient working capital to meet our working capital and capital expenditure requirements through at least April 30, 2004. However, if revenues decrease below that level without further expense reduction, or if cash is used for unanticipated purposes, we may need additional capital sooner than expected. Although we cannot guarantee that planned results will be obtained in fiscal 2004 or that sufficient debt or equity capital will be available to us under acceptable terms, if at all, we believe that our planned revenue and expense assumptions can be realized. However, if we are not successful in generating sufficient cash flow from operations or in raising additional capital when required in sufficient amounts and on terms acceptable to us, we could be unable to continue our operations. If we raise additional funds through the issuance of equity or convertible debt securities, the percentage ownership of our existing stockholders will be reduced.

Recent Accounting Pronouncements

In January 2003, the Financial Accounting Standards Board (“FASB”) issued Interpretation No. 46 (“FIN 46”), “Consolidation of Variable Interest Entities,” an interpretation of Accounting Research Bulletin No. 51, “Consolidated Financial Statements.” FIN 46 establishes accounting guidance for consolidation of variable interest entities that function to support the activities of the primary beneficiary. FIN 46 applies to any business enterprise, both public and private, that has a controlling interest, contractual relationship or other business relationship with a variable interest entity. We believe we have no investment in or contractual relationship or other business relationship with a variable interest entity and, therefore, the adoption of FIN 46 did not have any impact on our consolidated financial position or results of operations. However, if we enter into any such arrangement with a variable interest entity in the future, our consolidated financial position or results of operations may be adversely impacted.

In December 2002, the FASB issued Statement of Financial Accounting Standards (“SFAS”) No. 148, “Accounting for Stock-Based Compensation—Transition and Disclosure.” SFAS No. 148 amends SFAS No. 123, “Accounting for Stock-Based Compensation,” to provide alternative methods of transition for an entity that voluntarily changes to the fair-value method of accounting for stock-based employee compensation. In addition, Statement 148 requires more prominent disclosure of the effects of an entity’s accounting policy decisions with respect to stock-based employee compensation on reported results of operations, including per share amounts, in annual and interim financial statements. The disclosure provisions of SFAS No. 148 were effective immediately upon issuance in December 2002. As of April 30, 2003, we have no immediate plans to adopt the fair value method of accounting for stock-based employee compensation.

In November 2002, the FASB issued Interpretation No. 45 (“FIN 45”), “Guarantor’s Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others.” FIN 45 requires that a liability be recorded in the guarantor’s balance sheet upon issuance of a guarantee. In addition, FIN 45 requires disclosures about the guarantees that an entity has issued, including a reconciliation of changes in the entity’s product warranty liabilities. The initial recognition and initial measurement provisions of FIN 45 are applicable on a prospective basis to guarantees issued or modified after December 31, 2002, irrespective of the guarantor’s fiscal year end. The disclosure requirements of FIN 45 are effective for financial statements of interim or annual periods ending after December 15, 2002. We adopted FIN 45 during the year ended April 30, 2003, and it did not have a material impact on our consolidated financial position and results of operations.

In November 2002, the Emerging Issues Task Force (“EITF”) reached a consensus on Issue No. 00-21, “Revenue Arrangements with Multiple Deliverables.” EITF Issue No. 00-21 provides guidance on how to account for arrangements that involve the delivery or performance of multiple products, services and/or rights to use assets. The provisions of EITF Issue No. 00-21 will apply to revenue arrangements entered into in fiscal

36

Table of Contents

periods beginning after June 15, 2003. We do not believe that the adoption of EITF Issue No. 00-21 will have a material impact on our consolidated financial position and results of operations.

On January 1, 2003, we adopted SFAS No. 146, “Accounting for Costs Associated with an Exit or Disposal Activity.” SFAS No. 146 revises the accounting for exit and disposal activities under EITF Issue No. 94-3, “Liability Recognition for Certain Employee Termination Benefits and Other Costs to Exit an Activity (Including Certain Costs Incurred in a Restructuring),” by extending the period in which expenses related to restructuring activities are reported. A commitment to a plan to exit an activity or dispose of long-lived assets is no longer sufficient to record a one-time charge for most restructuring activities. Instead, companies record exit or disposal costs when they are incurred and can be measured at fair value. In addition, the resultant liabilities are subsequently adjusted for changes in estimated cash flows. SFAS No. 146 was effective prospectively for exit or disposal activities initiated after December 31, 2002. Companies may not restate previously issued financial statements for the effect of the provisions of SFAS No. 146, and liabilities that a company previously recorded under EITF Issue No. 94-3 are grandfathered. The adoption of SFAS No. 146 had no effect on our consolidated financial position and results of operations.

On May 1, 2002, we adopted SFAS No. 141, “Business Combinations,” and SFAS No. 142, “Goodwill and Other Intangibles Assets.” SFAS No. 141 eliminates the pooling-of-interests method of accounting for business combinations, except for qualifying business combinations that were initiated prior to July 1, 2001. Under SFAS No. 142, goodwill and indefinite-lived intangible assets are no longer amortized, but are reviewed annually for impairment or more frequently if impairment indicators arise. The adoption of SFAS Nos. 141 and 142 had no effect on our consolidated financial position or results of operations.

On May 1, 2002, we adopted SFAS No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets,” Statement 144 supersedes SFAS No. 121, “Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of,” and the accounting and reporting provisions relating to the disposal of a segment of a business of Accounting Principles Board Opinion No. 30. The adoption of SFAS No. 144 did not have a material impact on our consolidated financial position and results of operations.

On February 1, 2002, we adopted the provision in EITF Issue No. 01-9, “Accounting for Consideration Given by a Vendor to a Customer (Including a Reseller of the Vendor’s Products),” dealing with consideration from a vendor to a reseller under cooperative advertising and other arrangements. This provision of EITF Issue No. 01-9 states that consideration from a vendor to a reseller of the vendor’s products or services is presumed to be a reduction of the selling price of the vendor’s products or services, unless the vendor receives an identifiable benefit in return for the consideration and can reasonably estimate the fair value of the benefit received. If the amount of consideration paid by the vendor exceeds the estimated fair value of the benefit received, the excess amount is to be recorded by the vendor as a reduction of revenues. The adoption of this new guidance did not have a material effect on our consolidated financial position and results of operation.

Item 7A.    Quantitative and Qualitative Disclosures About Market Risk

Interest Rate Risk

We are subject to certain market risks, including changes in exchange rates and interest rates. We do not undertake any specific actions to cover our exposures to exchange and interest rate risks, and we are not a party to any risk management transactions. We do not purchase or hold any derivative financial instruments for trading purposes.

Our exposure to market risk for changes in interest rates relates primarily to our investment portfolio. As of April 30, 2003, we had approximately $22.8 million invested primarily in certificates of deposit and fixed-rate, short-term corporate and U.S. government debt securities, which are subject to interest rate risk and will decrease in value if market U.S. interest rates increase. We maintain a strict investment policy, which is intended to ensure

37

Table of Contents

the safety and preservation of our invested funds by limiting default risk, market risk and reinvestment risk. The following table presents notional amounts and related weighted-average interest rates by fiscal year of maturity for our investment portfolio as of April 30, 2003:

Foreign Currency Exchange Rate Risk

We develop products in the United States and sell them throughout the world. As a result, our financial results could be affected by factors such as changes in foreign currency exchange rates or weak economic conditions in foreign markets. Since all of our sales are currently made in United States dollars, a strengthening of the dollar could make our products less competitive in foreign markets. If any of the events described above were to occur, our net sales could be seriously impacted, since a significant portion of our net sales are derived from international operations. For the fiscal years 2003, 2002 and 2001, approximately 48%, 53% and 59%, respectively, of our total net sales were derived from customers outside of North America. In contrast, substantially all of the expenses of operating our foreign subsidiaries are incurred in foreign currencies. Specifically, the exposure includes intercompany loans, and third party sales or payments. As a result, our U.S. dollar earnings and net cash flows from international operations may be adversely affected by changes in foreign currency exchange rates. However, we do not consider the market risk associated with our international operations to be material. We do not currently use derivative financial instruments for hedging or speculative purposes.
