PART I.





Item 1.Business





The discussion in this
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 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, inability to raise additional capital, macroeconomic conditions, competition, new product introduction, key employee retention
and transitions, fluctuations in quarterly operating results, product concentration, technological changes, uncertainty in the web security appliance market, litigation, compliance with Nasdaqs listing standards, and other risks discussed in
item 1 under the heading Factors Affecting Future Operating Results and the risks discussed in our other Securities and Exchange Commission filings.





Overview





CacheFlow ® Inc., also referred to in this report as we or the Company, was incorporated in Delaware on March 16, 1996. We
are focused on the enterprise web security appliance market. Our web security appliances, called Security Gateways, 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 segments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 market segments 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 Security Gateway 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 web security appliance, which serves as a point of control and integration for multiple web security functions.





CacheFlow Solutions





Our suite of security products provide customers with application-level security, powerful policy-based control capabilities, comprehensive management and reporting functionality for applications such as authorization management,
virus scanning, content security, web usage monitoring, content filtering and bandwidth protection. 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 the users 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 Security Gateway provides a powerful authentication, authorization and
accounting system for web protection and control. Security Gateway 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 Security Gateway provides the power to define one set of powerful 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 Security Gateway 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 Security
Gateway 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.





Virus Scanning





Our Security Gateway provides a robust and flexible way to block viruses from web protocols inside and outside the firewall. The Security Gateways architecture is designed for handling web
requests that require scanning for potentially malicious mobile code and viruses. Security Gateways 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, Security Gateways can effectively sanitize web content. Security Gateways 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, Security Gateways can load-balance scanning
requests across multiple scanning servers, allowing security administrators to add scanning capacity as needed. Finally, Security Gateways automatically detect virus pattern updates on the virus scanning servers and mark content for rescan as
necessary. Security Gateways are compatible with leading virus scanning solutions, including ICAP versions of Symantecs CarrierScan Server and Trend Micros InterScan Server.





Content Security





Our
Security Gateway provides a robust and flexible way to manage web-based threats. Our products give security professionals the tools necessary to protect and control the network from a variety of new web-based threats. In addition, the Security
Gateway provides the visibility and flexible content policy capabilities needed to respond in cases where a security breach has occurred. With Security Gateways, security administrators can:





| |  |  | Block, strip and replace, or scan for viruses on a variety of content requests;
| | - |  | -------------------------------------------------------------------------------




| |  |  | Perform stripping of active content. For example, strip visual basic scripts for all users, but allow ActiveX for a specific group;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------




| |  |  | Block specific file extensions and mime-types from user requests;
| | - |  | -----------------------------------------------------------------



4




---

##### Table of Contents




| |  |  | Restrict the use of certain methods for a given user request. For example, a company may determine that only a certain group of employees are allowed to post
information to a partner site or accept attachments in web-based email;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------




| |  |  | Restrict uploading of information via multi-part forms or web-based email in order to prevent intellectual property from leaving the company;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------




| |  |  | Allow only a specific browser type due to potential security holes in non-approved browsers; and
| | - |  | ------------------------------------------------------------------------------------------------




| |  |  | Limit, or strip and replace what information is available in certain content headers so that information about the corporate network doesnt find its way
into the Internet.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------




Web Usage Monitoring





Our Security Gateway provides a robust and flexible way to monitor users and audit web and streaming traffic for both external and
internal content requests. The Security Gateways flexible logging features, 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 Security Gateway gives administrators and managers the ability to audit web traffic as needed. This processing point gives a complete 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 Security Gateway logs are standardized, customers can choose from a variety of commonly
available reporting tools or use the CacheFlow Reporter, described further on page 7.





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 Security Gateways 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. For example, an organization may decide gambling web sites should be completely blocked for everyone, while sports
sites may be allowed for HR-but all multimedia files are replaced with a corporate security message. Software-only solutions cannot scale to enterprise demands with this kind of granularity enabled. Our Security Gateway makes it possible by
integrating our policy architecture, specialized operating system and network hardware, and a cache that stores commonly accessed content for reuse. Security Gateways provide the performance and manageability required for enterprise-wide
policy-based content filtering.





Bandwidth Protection





Internet access impacts enterprise network performance. Left unchecked, streaming media and recreational web surfing can clog corporate
networks with unneeded traffic and starve mission-critical applications of the bandwidth necessary to run effectively. Protecting network bandwidth requires effectively controlling web traffic and required network resources. Our Security Gateway
provides a robust and flexible way to control and apply content-based protection policies for network bandwidth utilization. The Security Gateway can allow enterprises to create policies to constrain who can use certain media types (and how much of
it), limit certain users or network segments access to large amounts of data that potentially clog corporate networks, prevent all access to the Internet except for a group of users that need access to do their jobs (effectively freeing bandwidth
for mission-critical needs), and provide both on-demand and pre-positioning of content users commonly access (effectively optimizing the use of expensive WAN links through intelligent content positioning policies).

Products





We call our web security appliances a Security Gateway. We manufacture two main types of Security Gateways, the SG800 Series and the 6000 Series. These two types of Security Gateways 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, URL filtering software and CacheFlow Reporter, which are used in conjunction with our
Security Gateways. We also manufacture an appliance called Director, which is used primarily to manage large numbers of Security Gateways in a customers environment. Lastly, we currently still sell two legacy products, our model 700 and model
7000 server accelerators, and 6000 series client accelerators.





Security Gateway





Our Security Gateways are optimized appliances that serve as a point of integration for multiple enterprise security
applications, providing the protection, control and acceleration enterprises need to maximize investments in Web technology. The Security Gateway 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
Security Gateway appliances are comprised of a specialized hardware platform and our Security Gateway operating systems (SGOS). Our specialized hardware platforms provide industry-leading security, scalability and performance in an easy to deploy
form factor which is typically rack mounted, while the SGOS provides the comprehensive security and control application functionality enterprises require to protect their web-enabled networks. List prices for our Security Gateway and associated
products range from $6,000 to $150,000.





SG800 Series





The model 800 Security Gateway is a simple 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 gigabyte (GB) disk drive and 512 megabytes of random access memory (RAM) to systems with four 73 GB disk drives and 2GB of RAM.





6000 Series





The Model 6000 Security Gateway 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





CacheFlow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 Security Gateway. The Visual Policy Manager software is included as part of the Security
Gateway OS.





URL Filtering Software





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

Reporter





The CacheFlow Reporter is a powerful log processing and reporting product that generates out-of-the-box reports tailored for the Security Gateway. 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.





Director





The Director delivers scalable change management for Security Gateways. Built as an extensible management appliance, Director provides
configuration management, security and policy management, and resource management for enterprises deploying a large number of Security Gateways in their web security infrastructure. Director enables administrators to:





| |  |  | Reduce management costs by centrally managing all Security Gateways;
| | - |  | --------------------------------------------------------------------




| |  |  | Eliminate the need to configure remote devices manually;
| | - |  | --------------------------------------------------------




| |  |  | Rapidly deploy and upgrade Security Gateways;
| | - |  | ---------------------------------------------




| |  |  | Distribute user security policy across the network; and
| | - |  | -------------------------------------------------------




| |  |  | Recover from system problems with configuration snapshots and recovery.
| | - |  | -----------------------------------------------------------------------




Legacy Products





700
Series and 7000 Series Server Accelerators





Server accelerators are specifically designed to improve the
performance, scalability, security and manageability of high-traffic Web sites. They feature a high RAM-to-disk ratio and a built-in Secure Sockets Layer encryption/decryption processor. This processor can manage 10-40 times more secure sessions
than a standard Web server, allowing for the acceleration of both public (HTTP) and private (HTTPS) content. The system software, called CacheOS  Server Edition, is expressly tuned for the workload of a high-traffic Web site.





6000 Series Client Accelerator





Client accelerators enable
organizations, typically service providers, to effectively manage, distribute and accelerate content with high levels of speed and efficiency. 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 enterprise web
security appliance solutions by delivering high-performance, innovative Security Gateway appliances. Key elements of our strategy include the following:





Apply our Security Gateway Focus to the Enterprise Market Segment.    We are focused exclusively on developing Security Gateway appliances. We believe this
exclusive 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 web security appliances, the opportunity to sell to numerous customers and the level of existing competition.





Enhance Capabilities of our Security Gateway.    We intend to use our technological expertise to meet the needs of the evolving web security appliance market.
We plan to continue to develop both the software and




7

##### Table of Contents

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 Security Gateways
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 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 more fully in line 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 CacheFlow 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 $35.1 million, $27.7 million and $9.6 million for the fiscal years ended April 30,
2002, 2001 and 2000.





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 CacheFlow. 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 web security appliances by adding new features and strengthening
existing features.





The market for web security 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 web security 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.

##### Table of Contents




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 web security 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 experienced in the second half of fiscal year 2001, 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 web security
appliances is intensely competitive, evolving and subject to rapid technological change. Primary competitive factors that have typically affected our market include product features 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, primarily including Cisco Systems, Network Appliance, Tumbleweed Software and various others. In addition, we expect additional competition from other
established and emerging companies as the market for web security 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 web security 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




9




---

##### Table of Contents

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. Even when 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 U.S. patents by us (See Item 8, Note 13 Litigation
of the Consolidated Financial Statements). 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, 2002, we had a total of 238 employees, comprised of 84 in research and development, 88 in sales, 10 in marketing, 18 in
customer support, 11 in manufacturing and 27 in general and administrative. Of these employees, 175 were located in North America with 63 located internationally. None of our employees is 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, 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 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 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, inability to raise additional capital, macroeconomic conditions, competition, new product introduction, key employee retention and transitions, fluctuations in quarterly operating results, product concentration, technological
changes, uncertainty in the web security appliance market, litigation, compliance with Nasdaqs listing standards, and other risks discussed in this item under the heading Factors Affecting Future Operating Results and the risks
discussed in our other 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.





Risks Related to Our Business Execution





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 $247.0 million and $519.1 million for the years ended April 30, 2002 and 2001, respectively. As of April 30, 2002, we had an accumulated deficit of $849.1 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.





If we are unable to raise additional
capital, our ability to effectively manage our growth or enhance our products could be harmed.





At April 30,
2002, we had approximately $12.5 million in cash and cash equivalents and $27.5 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 web security 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.





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, CA and Redmond, WA 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 now believe we would 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. If
current market conditions for the commercial real estate market remain the same or worsen, we may be required to record additional charges.

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 eighteen months. 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. 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 18 months 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.





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 web security appliances is intensely competitive, evolving and subject to rapid technological changes. Primary competitive
factors that have typically affected our market include product features 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
primarily Cisco Systems, Network Appliance, Tumbleweed Software and various others. In addition, we expect additional competition from other established and emerging companies as the market for web security 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 web security 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.





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 resulted from




12




---

##### Table of Contents

the February 2002 restructuring, 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 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 or 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.





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 web security 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 web security appliance solutions, combined with the macro-economic slowdown, contributed to longer sales cycles in
fiscal year 2002 and a resulting decline in our sequential quarterly sales. We may experience order deferrals or loss of sales as a result of lengthening sales cycles.





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:





| |  |  | we have a limited operating history, and the market in which we compete is relatively new and rapidly evolving;
| | - |  | ---------------------------------------------------------------------------------------------------------------

| |  |  | our sales cycle varies substantially from customer to customer;
| | - |  | ---------------------------------------------------------------

##### Table of Contents




| |  |  | our sales cycle may lengthen as the complexity of web security appliance solutions continues to increase; and
| | - |  | -------------------------------------------------------------------------------------------------------------




| |  |  | our inability to predict the macro-economic conditions.
| | - |  | -------------------------------------------------------




A high percentage of our expenses, including those related to 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.





If we fail to expand and manage existing sales channels or create additional sales capabilities, our sales will not grow.





While we recently reduced our direct sales force in response to current market conditions, we will
continually evaluate and modify our current distribution strategy to meet market requirements. Any direct channel new hire or new distribution partner will require extensive training and typically take several months to achieve productivity.
Competition for qualified sales personnel and distribution partners is intense, and we might not be able to hire the kind and number of candidates we are targeting. If we fail to expand and manage existing sales channels or create additional sales
capabilities, our business will be seriously harmed.





Many of our indirect channel partners do not have minimum
purchase or resale requirements and carry products that are competitive with our products. These resellers 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 indirect channel partners or successfully recruit new indirect channel partners. Events or occurrences of this nature could seriously harm our business. We
may also fail to accomplish our goal to increase our focus on indirect distribution channels, which could significantly decrease sales.





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, 2002, sales to customers outside of the United States and Canada accounted for approximately 53% of our net sales. 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 the 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.





We disclose pro forma
financial information





We prepare and release quarterly unaudited financial statements prepared in accordance
with generally accepted accounting principles (GAAP). We also disclose and discuss certain pro forma financial information in the related earnings release and investor conference call. This pro forma financial information excludes
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 the
pro forma 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




14

##### Table of Contents

part of our Quarterly Reports on Form 10-Q, our Annual Reports on Form 10-K, and our quarterly earnings releases, and to compare the GAAP financial information with the pro forma financial
results disclosed in our quarterly earnings releases and investor calls, and read the associated reconciliation.





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. Our future success will depend, in significant part, on our ability to have others manufacture
our products cost-effectively and in sufficient volumes. 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 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, or lower 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




15




---

##### Table of Contents

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.





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 second half of fiscal year 2001, 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.





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 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.





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




16




---

##### Table of Contents

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, which alleges infringement of certain U.S. patents by us. (See Note 13 of the Consolidated Financial Statements) 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.





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 do 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.





Risks Related to the Web Security Appliance Market





The market for web security 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 web security appliances. The market for web security appliances is a new and rapidly
evolving market. If the market for web security 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 web security
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 web security 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.

##### Table of Contents




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.





We are entirely dependent on market acceptance of our web security appliances and, as a result, lack of market acceptance of these solutions could cause our sales to fall.





To date, our prior caching products and web security 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.





Risks Related to Litigation,
Government Regulations, Inquiries or Investigations





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.





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





Our customers install our web security appliance solutions 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. However, 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 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 on behalf of persons who purchased our stock
between November 18, 1999 and June 8, 2001 in the U.S. District Court for the Southern District of New York. These cases have been consolidated under the case captioned Colbert Birnet, LP v. CacheFlow, Inc., et al., Civil Action No. 1-01-CV-5143.
The complaints generally allege that various investment bank underwriters engaged in improper and undisclosed activities related to the allocation of shares in our initial public offering of securities and maintained artificially high after-market
prices. The complaints seek unspecified




18

##### Table of Contents

damages against the underwriters, our company, and certain of our current and former directors and officers. 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 offerings. The lawsuits against our company, 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 are collectively captioned In re Initial Public Offering Securities Litigation Civil Action No. 21-MC-92. We intend to defend against the allegations in the complaints vigorously and we believe the outcome would not have a
material adverse effect on the business, results of operations, or financial condition of our company. In the future, other types of securities class action lawsuits could be filed against us. 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 CacheFlow 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.





Risks
Related to Securities Markets





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





Our stock is currently traded on the Nasdaq National Market. Under Nasdaqs listing maintenance standards, if the closing bid price of a companys common stock remains under $1.00 per share for 30 consecutive trading days,
Nasdaq will issue a deficiency notice to that company. If the closing bid price does not reach at least $1.00 per share for a minimum of ten consecutive trading days during the 90 calendar days following the issuance of the deficiency notice from
Nasdaq, Nasdaq may delist that companys common stock from trading on the Nasdaq National Market. On May 10, 2002, we received a notice from Nasdaq stating that we were not in compliance with Nasdaqs continued listing requirements because
the minimum closing bid price per share of our Common Stock had remained below $1.00 for 30 consecutive trading days. The letter further stated that the closing bid price of our common stock must be at least $1.00 per share for ten consecutive
trading days during the 90-day period subsequent to May 10, 2002, or Nasdaq will delist our common stock from trading on the Nasdaq National Market on or about August 8, 2002. We expect to receive notice from Nasdaq that the failure of our Common
Stock to maintain Nasdaqs minimum closing bid price requirement of $1.00 has continued beyond the 90 day probationary period allowed under the Nasdaq National Marketplace Rules and, therefore, our Common Stock may be delisted. We intend to
appeal any such delisting decision, and the delisting could be stayed pending a hearing before the Nasdaq Qualifications Panel.





Furthermore, at the discretion of our Board of Directors, we intend to effect a reverse split of our common stock in order to attempt to regain compliance and continue to trade on the Nasdaq National Market. On July 15, 2002, the
Board of Directors unanimously adopted a resolution approving and recommending to the stockholders for their approval an amendment to our Amended and Restated Certificate of Incorporation to effect a reverse split of our outstanding shares of common
stock, in a ratio of either one-for-five, one-for-ten or one-for-fifteen, which ratio (assuming such ratio has been approved by our stockholders) will be chosen by the Board of Directors at any time prior to the date that is ninety days after our
2002 Annual Meeting of Stockholders. Our stockholders are being asked at the Annual Meeting to act upon a proposal to authorize the Board of Directors to file an amendment to our Amended and Restated Certificate of Incorporation and thereby effect
such a reverse stock split by voting in favor of each of the three proposed amendments. Assuming that our stockholders approve




19

##### Table of Contents

one or more of the proposed amendments, the Board of Directors will then choose one amendment from among the approved amendments, and will effect the reverse stock split in that approved ratio.
If one or more of the proposed reverse stock split amendments is approved by our stockholders, the Board of Directors intends to subsequently effect, in its sole discretion, the reverse stock split based upon any of the following ratios:
one-for-five, one-for-ten or one-for-fifteen, provided such ratio has been approved by our stockholders. The Board of Directors determination of the applicable ratio will be made with the primary purpose of retaining our Nasdaq National Market
listing and the liquidity of our common stock.





There can be no assurance that our common stock will remain
eligible for trading on the Nasdaq National Market. If our stock were delisted, the ability of our shareholders to sell any of our common stock would be severely, if not completely, limited. Furthermore, our ability to raise additional capital would
be severely impaired. As a result of these factors, the value of the common stock would decline significantly.





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, 2002, the closing market price of our common stock has fluctuated significantly, ranging from $0.47 to
$164.69. The market price of our common stock may fluctuate significantly in response to the following factors:





| |  |  | changes in macro-economic conditions;
| | - |  | -------------------------------------




| |  |  | variations in our quarterly operating results;
| | - |  | ----------------------------------------------




| |  |  | changes in financial estimates or investment recommendations by securities analysts;

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 ten
metropolitan areas in North America. We also lease space for sales and support in the following countries: Australia, France, Germany, Hong Kong, Japan, Peoples Republic of China, Singapore, South Korea, Spain, Sweden, Taiwan, United Arab
Emirates and the United Kingdom.





In February we announced a restructuring plan that included closing down the
research and development facilities in Redmond, Washington and Sunnyvale, California, and moving the research and development organization back into the headquarters facility in Sunnyvale, California. We have subleased the Sunnyvale, California
building for the remaining term of the lease. However, the Redmond, Washington facility remains vacant.





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

Overview





We have incurred net losses in each quarter since inception. As of April 30, 2002, we had an accumulated deficit of $849.1 million. Our net loss available to common
stockholders for the years ended April 30, 2002, 2001 and 2000 was $247.0 million, $519.1 million and $62.7 million, 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 year ended April 30, 2002. We believe this decline in revenue substantially 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 will continue throughout fiscal 2003. As a result, we expect to incur additional operating losses and continued negative cash flows from operations
through at least fiscal 2003. 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 predictive 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 of America. The preparation of these Consolidated Financial Statements requires us to make estimates and judgements 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 judgements, including those related to sales returns, bad debts, excess inventory and purchase commitments, investments,
intangible assets, lease losses and restructuring accruals, income taxes, and contingencies. We base our estimates on historical experience and assumptions that we believe to be reasonable under the circumstances. Actual results may differ from
those estimates.





We believe the accounting policies described below, among others, are the ones that most
frequently require us to make estimates and judgements, and therefore are critical to the understanding of our results of operations:





| |  |  | Revenue recognition and allowances;
| | - |  | -----------------------------------




| |  |  | Inventory write down;
| | - |  | ---------------------




| |  |  | Restructuring accruals; and
| | - |  | ---------------------------




| |  |  | Accounting for income taxes.
| | - |  | ----------------------------




Revenue Recognition and Allowances.    We generally recognize product revenue upon shipment, assuming that evidence of an arrangement exists, the fee is determinable and collectibility 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. Maintenance contract revenue is initially deferred when the customer purchases a
maintenance contract and recognized evenly over the life of the contract.





Probability of collection is assessed
on a customer by customer basis. Customers are subjected to a credit review process that evaluates the customers financial position and ultimately their ability to pay. 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 2002, revenue from several of our customers was recognized upon cash receipt.





We also maintain a separate allowance for doubtful accounts for estimated losses resulting from the inability of our customers to make required payments. 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 the allowance for doubtful
accounts. If the financial condition of our customers deteriorates, resulting in an impairment of their ability to make payments, additional allowances may be required.

Inventory write-down.    We write-down inventory for
estimated excess and obsolete inventory equal to the difference between the cost of inventory and the estimated fair value based upon assumptions about future 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 write-downs and other charges against earnings may be required.





Restructuring accruals.    In fiscal 2002, as a result of continuing unfavorable economic conditions and a reduction in information technology spending rates, we implemented two restructuring plans, which
included reductions in workforce and a consolidation of facilities.





We performed a comprehensive analysis of our
real estate facility requirements and identified excess facility space, which has subsequently been offered for sublease. Based upon the results of the analysis, during fiscal 2002, we recorded charges related to estimated facilities lease losses,
net of expected sublease income. In determining the net facilities charge, various assumptions were made, including the time period over which the facilities will be vacant, expected sublease terms and expected sublease rates. The charges recorded
were estimates in accordance with Statement of Financial Accounting Standards (SFAS) No. 5, Accounting for Contingencies, and represented the low end of an estimated range that may be adjusted upon the occurrence of future
triggering events. Triggering events may include, but are not limited to, changes in estimated time to sublease the facilities, sublease terms, sublease rates, and lease termination. Should operating lease rental rates decline or should it take
longer than expected to find a suitable tenant to sublease the facility, adjustments to the facilities lease losses liabilities may be necessary in future periods based upon the then-current actual events and circumstances.





In fiscal 2002, we also recorded charges for a reduction in workforce in response to a decline in customer demand and macroeconomic
conditions. See Item 8, Note 6 Restructuring Charges of the Consolidated Financial Statements for further discussion.





Accounting for income taxes.    Significant management judgment is required in determining the provision


for income taxes,
deferred tax assets and liabilities, and any valuation allowance recorded against the net deferred tax assets. The determination of our tax provision is subject to judgments and estimates due to operations in several tax jurisdictions outside the
United States.





Results of Operations





Net Sales.    Net sales decreased to $55.6 million for the fiscal year ended April 30, 2002 from $97.7 million in fiscal 2001, which was an
increase from $29.3 million in fiscal 2000. This decrease in fiscal 2002 was 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. The increase in fiscal 2001 revenue was due to higher sales volumes resulting from the introduction of our 600, 700, 6000 and 7000 series products and growth in our customer base as we
expanded our sales force.





During fiscal 2002, 2001 and 2000, no customer accounted for more than 10% of our net
sales. Net sales from international operations were $29.3 million, or 53% of net sales, in fiscal 2002, $57.6 million, or 59% of net sales, in fiscal 2001, and $14.1 million, or 48% of net sales, in fiscal 2000. We expect international revenue as a
percentage of total revenue to decrease moderately in fiscal 2003 compared to fiscal 2002.





Unless macroeconomic
conditions improve sooner than anticipated, we believe near-term demand for our products will remain soft in fiscal 2003. Once conditions improve, we expect our net sales to increase as a result of continued acceptance of our products in the
marketplace, although the initial year-over-year growth rate in our net sales that we experienced in 2000 and 2001 is not expected to occur in the future.

Gross Profit.    Gross profit decreased to $29.7
million in fiscal 2002 from $49.6 million in fiscal 2001, which was an increase from $18.1 million in fiscal 2000. Excluding a $1.4 million inventory write-down in the fourth quarter of fiscal 2002 and a $3.9 million inventory write-down in the
fourth quarter of fiscal 2001, gross margin decreased to 55.9% in fiscal 2002, and increased to 63.4% in fiscal 2001 from 61.7% in fiscal 2000. In fiscal 2002, continued changes in the market demand caused an additional write down of inventory.
Gross margin decreased in fiscal 2002 due to fixed manufacturing costs on lower volumes of sales. These fixed manufacturing costs were reduced with the February 2002 restructuring plan. The impact of the restructuring, however, is not expected to
impact gross margins until the first quarter of fiscal 2003. During the second half of fiscal 2001, excess inventories were built up in anticipation of projected sales volumes that never materialized as a result of the sharp deterioration in
macroeconomic conditions that caused customers to defer or delay capital expenditures on information technology. As a result, we wrote down $3.9 million of excess and obsolete inventories. Excluding this write off, increases in gross margin were
principally due to the introduction of higher margin products in fiscal 2001, the resulting economies of scale from higher unit production and cost savings achieved by outsourcing component manufacturing.





Our gross margin 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 increased to $35.1 million in fiscal 2002 from $27.7
million in fiscal 2001 and $9.6 million in fiscal 2000. These increases in research and development expenses in absolute dollars were primarily attributable to increases in staffing and associated support for engineers required to expand and enhance
our product line and, to a lesser extent, expenses related to prototype and testing costs. Research and development headcount decreased to 84 at April 30, 2002 from 204 at April 30, 2001, which was an increase from 68 at April 30, 2000. The decrease
in research and development headcount resulted from the restructuring plan in the fourth quarter of fiscal 2002, which is expected to result in significantly lower research and development expenses beginning in the first quarter of fiscal 2003.





As a percentage of net sales, research and development expenses increased to 63.1% in fiscal 2002 from 28.3% in
fiscal 2001, which was a decrease from 32.9% in fiscal 2000. This increase in research and development expenses as a percentage of net sales results from both the significant decrease in sales during fiscal 2002, and the significant increase in
expenses. 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 the continued lower revenue levels. Through April 30, 2002, all research and development costs have been expensed as incurred. We expect research and development expenses to decrease beginning with the first quarter of fiscal 2003 as a result of
the restructuring plan implemented in February 2002. 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 to increase headcount to provide for development of new products. However, should sales decline further in future periods, we may implement additional cost-cutting 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, and customer service and support costs. Sales and marketing expenses decreased to $30.0 million in fiscal 2002 from $61.5 million in fiscal 2001, which was an




26

##### Table of Contents

increase from $28.9 million in fiscal 2000. The decrease in sales and marketing expenses in absolute dollars in 2002 is related to the reduction of headcount. Sales and marketing headcount
decreased to 98 at April 30, 2002 from 211 at April 30, 2001, which was an increase from 173 in fiscal 2000. As a percentage of net sales, sales and marketing expenses decreased to 54.0% in fiscal 2002 from 62.9% in fiscal 2001, and from 98.7% in
fiscal 2000. These decreases in sales and marketing expenses as a percentage of net sales occurred even with the lower revenue experienced in fiscal 2002, reflecting our efforts to lower such expenditures to keep more in line with the reduced
revenue that we are experiencing. 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-cutting programs to further
reduce our sales and marketing expenses.





General and Administrative.    General and
administrative expenses decreased to $9.5 million in fiscal 2002 from $10.5 million in fiscal 2001, which was an increase from $4.8 million in fiscal 2000. The decrease in general and administrative expenses in absolute dollars for fiscal 2002 is
primarily attributable to decreased staffing and associated expenses. General and administrative headcount decreased to 27 at April 30, 2002 from 55 at April 30, 2001, which was an increase from 39 at April 30, 2000. As a percentage of net sales,
general and administrative expenses increased to 17.1% in fiscal 2002 from 10.8% for in fiscal 2001, which was a decrease from 16.2% in fiscal 2000. The increase in general and administrative expenses as a percentage of net sales primarily resulted
from the decline in sales experienced in fiscal 2002 compared to fiscal 2001 and the increase in the provision for bad debt expense in the second quarter of our fiscal 2002. We expect general and administrative expenses to decrease beginning with
the first quarter of our fiscal 2003 as a result of the restructuring plan implemented in February 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 general and administrative expenses to increase in absolute dollars and to increase headcount to manage expanding operations and facilities. However, should sales decline further in future periods, we may implement additional
cost-cutting programs to further reduce our general and administrative expenses.





Stock
Compensation.    Stock compensation expense decreased to $19.5 million in fiscal 2002 from $69.2 million in fiscal 2001, which was an increase from $38.4 million in fiscal 2000. This non-cash charge reflects the amortization
of deferred stock compensation and termination and acceleration charges for departing employees. Stock compensation expense decreased significantly in fiscal 2002 compared to fiscal 2001 and 2000 as a result of the decreasing amount of amortization
of stock compensation, most of which 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 non-recurring deferred stock compensation charge of $28.1 million in connection with the accelerated vesting of certain unvested stock options held by our former chairman. Based on the options granted through April
30, 2002, we have a remaining balance of $3.6 million in deferred stock compensation, approximately $3.0 million of which we expect will be amortized in fiscal 2003.





Goodwill Amortization.    Goodwill amortization decreased to $29.5 million in fiscal 2002 from $99.0 million in fiscal 2001, which was an
increase from no charges in fiscal 2000. This decrease in 2002 was primarily attributable to the cumulative $407.0 million impairment of assets written off in the quarters ended April 30, 2001, July 31, 2001, October 31, 2001, January 31, 2002 and
April 30, 2002 that ultimately decreased our entire goodwill balance to zero. Furthermore, the purchase price accounting for the acquisition of Entera was completed during the quarter ended January 31, 2002, resulting in a reduction of $0.7 million
to goodwill. For additional discussion regarding impaired goodwill, refer to the Impairment of Assets section below.





Acquired In-Process Technology.    We recorded a non-recurring, non-cash $32.2 million charge in fiscal 2001 for the value of in-process technology acquired in the Entera transaction, which relates to
in-process technology 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 2000.

##### Table of Contents




There were two projects included in the in-process technology for Entera. The
efforts required to complete the acquired in-process technology 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 technology 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 technology was expensed in the period the transaction was consummated.





Restructuring.    As discussed further in the Reorganization Plans section below and in Item 8, Note 6 Restructuring
Charges below, we recorded a non-recurring $15.5 million charge related to facilities closure costs, lease abandonment costs, certain employee severance costs and contract termination costs for fiscal 2002.





Impairment of Assets.    As discussed further in the Asset Impairment section below, during each
quarter of fiscal 2002 we performed an impairment assessment of our tangible and intangible assets and determined that enterprise-level goodwill associated with the SpringBank and Entera acquisitions was impaired. As a result, a $134.1 million
impairment charge was recorded to write our enterprise-level goodwill net book value down to zero in fiscal 2002. In addition, a $272.9 million impairment charge was recorded in fiscal 2001.





Interest Income and Other Expense.    Net interest income and other expenses decreased to $1.6 million in fiscal 2002 from $6.4 million in fiscal
2001, which was an increase from $3.0 million in fiscal 2000. In general, the decreases in interest income and other expenses are due to the lower interest rates and cash available for investment. The net interest income and other expenses of $1.6
million recorded for fiscal 2002 include $0.4 million, which reflects an other than temporary decline in value of our available-for-sale securities.





Provision for Income Taxes.    The provision for income taxes increased to $0.5 million in fiscal 2002 from $0.3 million in fiscal 2001, which was an increase from $0.1
million in fiscal 2000, and is composed entirely of foreign corporate income taxes. 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 minimum profits the foreign operations generated for services provided to us. Our tax expense for fiscal 2003 will continue to be significantly dependent on the amount and mix of income derived
from sources subject to corporate income taxes of foreign taxing jurisdictions.





Accretion of Preferred
Stock.    In fiscal 2000, a non-recurring $2.0 million charge was recorded in connection with the November 1999 issuance of 280,953 shares of Series D preferred stock at $11.00 per share to accrete the stock to its fair
value. During November 1999, all of the shares of Series D preferred stock converted to common stock upon completion of our initial public offering.





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 2.7 million shares of CacheFlow 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.

##### Table of Contents




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 3.4 million shares of CacheFlow common stock with a fair value of approximately $370.8 million, the assumption of approximately 400,000 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 and $71.8 million for the years ended April 30, 2001 and 2000. We did not record any deferred stock compensation in fiscal 2002. Deferred stock compensation
results from a variety of stock-based transactions. Our stock compensation balance generally represents the difference between the exercise price and the deemed fair value of stock options and warrants granted to employees, consultants, directors
and third parties on the date such stock awards were granted. 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 or instances where certain modifications are made to the terms and conditions of option grants subsequent to the grant date. Related stock compensation expense is recorded over the option vesting period, generally two to four years, or
immediately if there is no vesting period. We recorded stock compensation expense of approximately $19.5 million, $69.2 million and $38.4 million for the years ended April 30, 2002, 2001 and 2000. We may record additional compensation 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 compensation expense, which is primarily attributable to amortization of deferred compensation charges, to impact our reported results through April 30, 2003.





Reorganization Plans





Fiscal 2002





As discussed in Item 8, Note 6 Restructuring Charges of the
Consolidated Financial Statements, in February 2002, our Board of Directors approved a restructuring program to significantly reduce our operating expenses and to further align our organization with current market conditions, future revenue
expectations and our planned future product direction. This plan involved the following steps:





| |  |  | Reducing our workforce by 200 employees, which represented approximately 45% of our workforce;
| | - |  | ----------------------------------------------------------------------------------------------




| |  |  | Closing and relocating two research and development facilities to the Sunnyvale, California headquarters location;
| | - |  | ------------------------------------------------------------------------------------------------------------------




| |  |  | Downsizing our international operations and discontinuing plans to fund additional international expansion (we will continue to manage current international
investments); and
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------




| |  |  | Canceling certain vendor contracts that existed prior to the restructuring and enhancing productivity in our operations in an effort to reduce costs.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------




In connection with this restructuring plan, we accrued approximately $12.9 million in the
quarter ended April 30, 2002 relating to employee severance costs, facilities closure costs, lease abandonment costs and contract termination costs. All employees were notified of their termination prior to April 30, 2002. Estimates related to
sublease costs and income are based on assumptions regarding sublease rates and the time required to locate sub-lessees that were derived from market trend information provided by a commercial real estate broker.




29

##### Table of Contents

These estimates will be 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. As of April 30, 2002, substantially all severance costs related to domestic employees had been paid and $10.5 million remain accrued for lease abandonment costs, contract termination costs and certain international
employee severance costs. The lease abandonment costs will be paid over the respective terms through 2007.





In
August 2001, our Board of Directors approved a restructuring program in response to the continued economic slowdown that negatively impacted in the 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 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 to complete this effort, which included employee severance costs of approximately $1.7 million and certain contract termination costs of approximately $0.9 million. As of April 30, 2002, severance payments to domestic and
international employees were substantially completed, and of the $2.6 million restructuring charges, $2.3 million had been paid, leaving a remaining accrual of $0.3 million for contract termination fees on our balance sheet.





Fiscal 2001





In February 2001, our Board of Directors approved a restructuring program instituted in response to the economic slowdown that negatively impacted the demand for our products in the fourth quarter of
fiscal year 2001, as potential customers deferred spending on their Internet and intranet infrastructure. As part of the restructuring program, we implemented a reduction in workforce by 52 employees and incurred $1.9 million in restructuring
charges, which included employee severance costs of approximately $1.3 million and certain contract termination costs of approximately $0.6 million. At April 30, 2001, $0.9 million of $1.9 million in restructuring charges remain accrued. As of
October 31, 2001, these severance and contract termination payments were completed.





We cannot assure 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 subsequent increases in headcount and subsequent facilities additions related to our operating requirements. See Item 8, Note 6 Restructuring Charges of the Consolidated Financial Statements for further discussions.





Asset Impairment





In fiscal 2002, management performed on a quarterly basis an impairment assessment of long-lived assets and determined that certain enterprise level goodwill recorded in connection with our Springbank and Entera acquisitions
was not fully recoverable. The assessment was performed primarily due to the significant decline in our stock price, the net book value of assets significantly exceeding our market capitalization, and the overall decline in industry growth rates.
The overall decline in industry growth rates indicates that this trend may continue for an indefinite period. As a result, we recorded $134.1 million in impairment charges in fiscal 2002 to fully write off goodwill based on the market value method.
The estimate of fair value was based upon our average market capitalization, which was calculated using our average closing stock price surrounding July 31, 2001, October 31, 2001, January 31, 2002 and April 30, 2002.





Additionally, we recorded a write-down of $4.7 million of certain leasehold improvements, computer software and hardware in fiscal 2002.
The leasehold improvements write-down related to two research and development facilities, which were closed in connection with our February 2002 restructuring plan.





Liquidity and Capital Resources





From inception, we
financed our operations and the purchase of property and equipment through private sales of preferred stock, bank loans, equipment leases, and an initial public offering of our common stock. At April 30, 2002, we had $12.5 million in cash and cash
equivalents, $27.5 million in short-term investments, and $29.7 million in working capital.

##### Table of Contents




Net cash used in operating activities was $40.9 million in fiscal 2002, $54.1
million in fiscal 2001 and $23.6 million in fiscal 2000. 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 operating activities beginning with the first quarter of our fiscal 2003.





Cash used in operating
activities in the fiscal 2002 includes $2.4 million of payments against accrued restructuring liabilities related to terminated and vacated real estate leases. We expect to make payments of approximately $3.4 million against our accrued
restructuring liabilities over the next 12 months.





Net cash used in investing activities was $2.9 million in
fiscal 2002, net cash provided by investing activities was $3.5 million in fiscal 2001, and net cash used in investing activities was $37.9 million in fiscal 2000. Net cash used in investing activities was primarily attributable to purchases of
property, plant and equipment, and to a lesser extent, to purchases of short-term securities. Net cash provided by investing activities was primarily due to sales of investment securities and cash acquired in business acquisitions, partially offset
by purchases of property and equipment. We expect that, in the future, any cash in excess of current requirements will continue to be invested in short-term investment grade, interest-bearing securities.





Capital expenditures were $2.6 million in fiscal 2002, $9.8 million in fiscal 2001 and $4.0 million in fiscal 2000. Our capital
expenditures consisted primarily of purchases of computer, equipment and software, furniture and leasehold improvements.





Net cash provided by financing activities was $0.9 million in fiscal 2002, $14.5 million in fiscal 2001 and $150.7 million in fiscal 2000. Financing activities for fiscal 2002 were primarily attributable to the exercise of employee
stock options. In fiscal 2001, we raised $15.0 million from the exercise of employee stock options, partially offset by employee stock repurchases. In fiscal 2000, financing came from numerous sources:





| |  |  | During May 1999, we raised approximately$20.0 million in gross proceeds from the sale of Series C Preferred Stock at $4.575 per share.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------




| |  |  | During October 1999, we raised approximately $2.8 million through the cash exercise of options granted to a board member and consultant to purchase 702,380
shares of common stock at $4.00 per share.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------




| |  |  | During November 1999, we raised approximately $3.1 million through the sale of 280,953 shares of Series D Preferred Stock at $11.00 per share.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------




| |  |  | During November 1999, we raised approximately $126.5 million, net of underwriting discounts, commissions and offering costs, through sale of 5,750,000 shares of
our common stock in an initial public offering at $24.00 per share.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------




During December 1999, $4.5
million of the initial public offering proceeds were used to repay all of our outstanding debt.





We have no
material commitments or obligations other than those under leases. We do have minimal royalty and purchasing payment commitments in the ordinary course of our business. As of April 20, 2002, 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 such losses for fiscal 2003. Our current business plan for 2003 reflects continued initiatives to increase revenue, reduce overhead, and realize the




31

##### Table of Contents

benefit of recent reductions in employee headcount and occupancy costs. The plan projects that the amount of the quarterly net loss will decline from quarter to quarter with net income projected
to begin in fiscal 2004. As a result, current cash and short-term investment balances are projected to be sufficient to fund the excess of expenses over revenue for the year. In our review of our operating requirements, we determined that even with
a reduction of revenue in excess of 50% from fiscal 2002, we would still have sufficient working capital to meet our working capital and capital expenditure requirements through at least fiscal 2003. If revenues decrease below that level without
further expense reduction or if cash is used for unanticipated uses, we may need additional capital sooner than expected. Although we cannot guarantee that planned results will be obtained in fiscal 2003 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 will eventually 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 July 2001, the FASB issued Statements of Financial Accounting Standards No. 141, Business Combinations (Statement 141), and No. 142,
Goodwill and Other Intangible Assets (Statement 142). Statement 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. Statement
141 further clarifies the criteria to recognize intangible assets separately from goodwill. The requirements of Statement 141 are effective for any business combination accounted for by the purchase method that is completed after June 30, 2001.





Under Statement 142, goodwill and indefinite lived intangible assets are no longer amortized but are reviewed
annually (or more frequently if impairment indicators arise) for impairment. Separable intangible assets that are not deemed to have an indefinite life will continue to be amortized over their useful lives. The amortization provisions of Statement
142 apply to goodwill and intangible assets acquired after June 30, 2001. With respect to goodwill and intangible assets acquired prior to July 1, 2001, companies are required to adopt Statement 142 in their fiscal year beginning after December 15,
2001 (i.e., May 1, 2002 for our fiscal year).





The provisions of each statement, which apply to goodwill and
certain intangibles acquired prior to June 30, 2001 will be adopted by us on May 1, 2002. We believe the adoption of this statement will not have a material impact on our consolidated financial statements.





In October 2001, the FASB issued Statement of Financial Accounting Standards No. 144 (Statement 144), Accounting for the Impairment
or Disposal of Long-Lived Assets, which is effective for companies with fiscal year end beginning after December 15, 2001 (i.e., May 1, 2002 for our fiscal year). Statement 144 supersedes FASB Statement 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. We believe the adoption
of this statement will not have a material impact on our consolidated financial statements.





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, 2002, we had approximately $40.1 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

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 2002, 2001 and 2000,
approximately 53%, 59% and 48%, 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. We, however, 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.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS







Note 1.    Business





We were organized and incorporated in the state of Delaware on March 16, 1996. We operate in one segment to design, develop, market and
support web security appliance solutions.





Note 2.    Summary of Significant Accounting Policies





Basis of Presentation





The consolidated financial statements include the accounts of the Company and our wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. Certain
prior year amounts in the consolidated statements of operations have been reclassified to conform to the current period presentation. These classifications did not affect net income.





We have suffered recurring losses from operations and currently project such losses for fiscal 2003. Our current business plan for 2003 reflects continued initiatives to
increase revenue, reduce overhead, and realize the benefit of recent reductions in employee headcount and occupancy costs. The plan projects that the amount of the quarterly net loss will decline from quarter to quarter with net income projected to
begin in fiscal 2004. As a result, current cash and short-term investment balances are projected to be sufficient to fund the excess of expenses over revenue for the year. Although we cannot guarantee that planned results will be obtained in fiscal
2003 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.





Use of Estimates





The
preparation of the consolidated financial statements and the related disclosures in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported
in the consolidated financial statements and accompanying notes. For us, these estimates include returns and allowances, valuation reserves for inventories, accrual of warranty costs, impairment charges related to long-lived assets, restructuring
reserves, useful lives assigned for depreciation and amortization, income taxes, and contingencies. Actual results will differ from those estimates, and such differences could be material to the consolidated financial position and results of
operations.





Cash and Cash Equivalents





We consider all highly liquid investments with an original maturity of three months or less when purchased to be cash equivalents, which consisted primarily of commercial
paper investments at April 30, 2002 and 2001.





Short-Term Investments





Short-term investments consist primarily of debt securities with original maturities between three months and two years. Management
determines the appropriate classification of debt and equity securities at the time of purchase and evaluates such designation as of each balance sheet date based on its intent and ability to use such funds for current operations. To date, all
marketable debt securities have been classified as available-for-sale and are carried at fair value with unrealized gains and losses, if any, included in accumulated other comprehensive income (loss) in stockholders equity. The fair value of
these securities is based on quoted market prices. Realized gains and losses and declines in value of securities judged to be other than temporary are included in interest income and have not been significant to date. Interest and dividends on all
securities are included in interest income.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS(Continued)







Restricted Investments





Restricted investments comprise amounts held in deposits under irrevocable standby letters of credit that are required as collateral for a
research and development facility operating lease agreement, and for certain inventory purchases in the ordinary course of business.





Credit Risk and Customer Concentration





Financial instruments that potentially
subject us to credit risk consist of demand deposit accounts, money market accounts, commercial paper, corporate debt securities and trade receivables. We maintain our demand deposit accounts and our money market accounts primarily with one
financial institution. Our investment advisors are instructed to only invest in high-quality, investment grade securities and to limit investment exposure in any one issue. Management believes the financial risks associated with these financial
instruments are minimal.





We generally do not require collateral for sales to customers. For the years ended April
30, 2002, 2001 and 2000, no customers individually accounted for over 10% of our net sales. Based on our history level of un-collectibles, we believe that we have adequate reserves to cover our losses.





Concentrations of Supply





We currently purchase several key parts and components used in the manufacture of our products from limited sources of supply.





Inventories





Inventories
consist of raw materials, work-in-process and finished goods. Inventories are recorded at the lower of cost or market using the first-in, first-out method, after appropriate consideration has been given to obsolescence and inventory in excess of
anticipated future demand.





During the fourth quarters ended April 30, 2002 and 2001, we performed a lower of cost
or market and obsolescence assessment of our inventories and determined that a portion of our raw material components was recorded above market and that certain inventories were excess or obsolete. These excess and overvalued inventories resulted
from the estimated demand of such inventory in future periods. As a result, we recorded approximately $1.4 million and $3.9 million in additional write-downs of inventories to the lower of cost or market and to write-off excess or obsolete inventory
for the periods ended April 30, 2002 and 2001, respectively.





Property and Equipment





Property and equipment are stated at cost less accumulated depreciation and amortization. Depreciation and amortization are
provided on a straight-line basis over the lesser of the estimated useful life, generally three to five years, or the lease term of the respective assets.





Intangible Assets





Our primary intangible asset was
goodwill, which resulted from business combinations accounted for as purchases, and was recorded at amortized cost and was included in Intangible assets, net on our balance sheet. Amortization was computed using the straight-line method
over a period of three years. Accumulated goodwill amortization was $128.5 million and $99.0 million as of April 30, 2002 and 2001, respectively.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS(Continued)







Long-lived Assets





We evaluate our long-lived assets in accordance with the Financial Accounting Standards Boards (FASB) Statement of Financial
Accounting Standards No. 121, Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of, which requires impairment losses to be recorded on long-lived assets used in operations, such as property,
equipment and improvements, and intangible assets, when indicators of impairment are present and the undiscounted cash flows estimated to be generated by those assets are less than the carrying amount of the assets.





We also periodically assess the impairment of enterprise level goodwill in accordance with the provisions of Accounting Principles Board
(APB) Opinion No. 17, Intangible Assets. An impairment review is performed quarterly, or whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Factors that we consider important which could trigger an
impairment review include, but are not limited to, significant underperformance relative to historical or projected future operating results, significant changes in the manner of use of the acquired assets or the strategy for our overall business,
significant negative industry or economic trends, a significant decline in our stock price for a sustained period, and our market capitalization relative to net book value. When we determine that the carrying value of our long-lived assets may not
be recoverable based upon the existence of one or more of the above indicators of impairment, we measure any impairment using the market value method. This method estimates fair value based upon our average market capitalization, which is calculated
using our average closing stock price surrounding the measurement date.





Revenue Recognition





We generally recognize product revenue upon shipment, assuming that evidence of an arrangement exists, the fee is determinable
and collectibility is probable, unless we have future obligations for installation or must obtain customer acceptance, in which case revenue is deferred until these obligations are met. Maintenance contract revenue is initially deferred when the
customer purchases a maintenance contract and recorded evenly over the life of the contract. Maintenance contract revenue recognized for the years ended April 30, 2002, 2001 and 2000 was $7.4 million, $4.4 million and $0.4 million, respectively.
Probability of collection is assessed on a customer by customer basis. Customers are subjected to a credit review process that evaluates the customers financial position and ultimately their ability to pay. 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 2002, revenue from several of our customers was recognized upon cash receipt.





Research and Development





Costs to develop our products are expensed as incurred.





Warranty Reserves





Our products generally carry a one-year warranty. An estimate of our
warranty obligation, including the cost of replacement parts, is accrued at the time the related product revenue is recognized.





Advertising Costs





We expense advertising costs as incurred. Advertising expenses for the
years ended April 30, 2002, 2001 and 2000 were $0.3 million, $2.1 million and $0.5 million, respectively, and are included in sales and marketing expenses.

Income Taxes





We use the liability method to account for income taxes as required by the FASBs Statement of Financial Accounting Standards No.
109, Accounting for Income Taxes. Under this method, deferred tax assets and liabilities are determined based on differences between financial reporting and tax bases of assets and liabilities. Deferred tax assets and liabilities are
measured using enacted tax rates and laws that will be in effect when the differences are expected to reverse.





Comprehensive Loss





We report comprehensive loss in accordance with the FASBs
Statement of Financial Accounting Standards No. 130, Reporting Comprehensive Income. Included in other comprehensive income (loss) are adjustments to record unrealized gains and losses on available-for-sale securities. These adjustments
are accumulated in Accumulated other comprehensive loss in the stockholders equity section of the balance sheet.

Stock-Based Compensation





We account for stock-based compensation with respect to stock options granted to employees and officers using the intrinsic value based
method in accordance with APB Opinion No. 25, Accounting for Stock Issued to Employees and Financial Accounting Standards Board Interpretation No. 44, Accounting for Certain Transactions Involving Stock Compensation (an
Interpretation of APB Opinion No. 25). Stock options granted to non-employees are accounted for using the fair value method in accordance with Statement of Financial Accounting Standard No. 123, Accounting for Stock-based
Compensation (FAS 123). In addition, with respect to stock options granted to employees, we provide pro-forma information as required by FAS 123 showing the results of applying the fair value method using the Black-Scholes option pricing
model.





We account for equity instruments issued in exchange for the receipt of goods or services from other than
employees in accordance with FAS 123 and the conclusions reached by the Emerging Issues Task Force in Issue No. 96-18, Accounting for Equity Instruments That Are Issued to Other Than Employees for Acquiring, or in Conjunction with Selling,
Goods or Services (EITF 96-18). Costs are measured at the estimated fair market value of the consideration received or the estimated fair value of the equity instruments issued, whichever is more reliably measurable. The value of equity
instruments issued for consideration other than employee services is determined on the earliest of a performance commitment or completion of performance by the provider of goods or services as defined by EITF 96-18.





Net Loss Per Common Share





Basic net loss per common share and diluted net loss per common share are presented in conformity with the FASBs Statement of Financial Accounting Standards No. 128, Earnings Per
Share (FAS 128), for all periods presented.




43

##### Table of Contents



CACHEFLOW, INC.





NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS(Continued)







In accordance with FAS 128, basic and diluted net loss per common share has been computed
using the weighted-average number of shares of common stock outstanding during the period, less the weighted average number of shares of common stock issued to founders, employees and consultants that are subject to repurchase. Pro forma basic and
diluted net loss per common share, as presented in the condensed consolidated statements of operations, have been computed as described above and also give effect, under Securities and Exchange Commission guidance, to the conversion of the
convertible preferred stock (using the if-converted method) from the original date of issuance. The shares used in calculating the pro forma basic and diluted net loss per common share amounts also include certain warrants to purchase preferred
stock as such warrants expired upon the completion of our initial public offering of our common stock in November 1999.





The following table presents the calculation of basic and diluted net loss per common share and pro forma basic and diluted net loss per common share (in thousands, except per share amounts):

We have excluded preferred stock, warrants and outstanding stock
options from the calculation of diluted net loss per common share that are antidilutive for all periods presented. The total number of such shares not included in the calculations of diluted net loss per common share was (in thousands) 10,194,
18,289 and 14,784, for the three years ended April 30, 2002, 2001 and 2000, respectively.





Foreign Currency
Adjustments





Management has determined that the functional currency of our domestic and foreign operations is
the U.S. dollar. Accordingly, the effects of foreign currency transactions, and of remeasuring the financial position and results of operations from local currencies into the functional currency, are included in other expense. These
amounts have not been material for each of the three years in the period ended April 30, 2002.





Fair Value of
Financial Instruments





The carrying amounts of our financial instruments, which include cash equivalents and
short-term investments, approximate their fair values based on quoted market prices.





Segment Information





We operate in one segment, to design, develop and market web security appliances that are specifically
designed, or purpose-built, to 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. The chief operating decision maker makes
operating decisions and allocates resources based on financial data consistent with the presentation in the accompanying financial statements.





Recent Accounting Pronouncements





In July 2001, the FASB issued Statements of Financial
Accounting Standards No. 141, Business Combinations (Statement 141), and No. 142, Goodwill and Other Intangible Assets (Statement 142). Statement 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. Statement 141 further clarifies the criteria to recognize intangible assets separately from goodwill. The requirements of Statement 141 are effective for any business
combination accounted for by the purchase method that is completed after June 30, 2001.





Under Statement 142,
goodwill and indefinite lived intangible assets are no longer amortized but are reviewed annually (or more frequently if impairment indicators arise) for impairment. Separable intangible assets that are not deemed to have an indefinite life will
continue to be amortized over their useful lives. The amortization provisions of Statement 142 apply to goodwill and intangible assets acquired after June 30, 2001. With respect to goodwill and intangible assets acquired prior to July 1, 2001,
companies are required to adopt Statement 142 in their fiscal year beginning after December 15, 2001 (i.e., May 1, 2002 for our fiscal year).





The provisions of each statement, which apply to goodwill and certain intangibles acquired prior to June 30, 2001 will be adopted by us on May 1, 2002. We believe the adoption of this statement will
not have a material impact on our consolidated financial statements.





In October 2001, the FASB issued Statement
of Financial Accounting Standards No. 144 (Statement 144), Accounting for the Impairment or Disposal of Long-Lived Assets, which is effective for companies with fiscal year end beginning after December 15, 2001 (i.e., May 1, 2002 for our
fiscal year). Statement 144 supersedes FASB Statement 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. We believe the adoption of this statement will not have a material impact on our consolidated financial statements.





Note 3.    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 2.7 million shares of CacheFlow
common stock, approximately $7.0 million of assumed liabilities and approximately $2.0 million in transaction costs. Substantially all of the $177.0 million purchase price was allocated to goodwill, which was fully amortized and written off during
fiscal 2002. For further discussion regarding goodwill, refer to Note 5, Impairment of Assets.





Entera, Inc.On December 15, 2000, we completed the acquisition of Entera, Inc. (Entera), a company that developed standards-based streaming content distribution and management technologies, in a
stock-for-stock merger transaction accounted for as a purchase. Purchase consideration was approximately $411.9 million

##### Table of Contents



CACHEFLOW, INC.





NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS(Continued)




consisting of approximately 3.4 million shares of CacheFlow common stock with a fair value of approximately $370.8 million, the assumption of approximately 400,000 outstanding stock options
with a fair value of approximately $40.0 million, and approximately $1.1 million in transaction costs. Since December 15, 2000, the results of operations of Entera have been included in our Consolidated Statements of Operations.





The fair value of the common stock issued is based on the average closing price of our common stock
surrounding October 10, 2000. The fair value of the Entera options assumed is based on the Black-Scholes model using the following assumptions:





| |  |  | Expected lives of 9 years;
| | - |  | --------------------------




| |  |  | Expected volatility factor of 1.54;
| | - |  | -----------------------------------




| |  |  | Risk-free interest rate of 6.25%; and
| | - |  | -------------------------------------




| |  |  | Expected dividend rate of 0%.
| | - |  | -----------------------------




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 Note 5, Impairment of Assets. Deferred stock compensation associated with unvested stock options issued to
employees in conjunction with the acquisition is included as a reduction to stockholders equity and is being amortized by charges to operations using a graded method over the vesting period of each respective option, consistent with the method
described in Financial Accounting Standards Board Interpretation No. 28. For the year ended April 30, 2001, we recorded $6.5 million of amortization of deferred compensation related to stock options assumed for Entera employees.

Note 5.    Impairment of Assets





Given the current economic uncertainty and the general volatility of the financial markets, our stock price and market capitalization have
significantly declined and fallen below our net book value for the four consecutive quarters in fiscal 2002. We performed an impairment assessment of long-lived assets on a quarterly basis during fiscal 2002 and determined that certain enterprise
level goodwill recorded in connection with our Springbank and Entera acquisitions is not fully recoverable. As a result, we recorded a $134.1 million impairment charge in fiscal 2002 to reduce goodwill to its estimated fair value based on the market
value method. The estimate of fair value was based upon our average market capitalization, which was calculated using our average closing stock price surrounding July 31, 2001, October 31, 2001, January 31, 2002 and April 30, 2002. As of April 30,
2002, goodwill is fully written off and there is currently no more remaining goodwill balance to be amortized in fiscal 2003. Additionally, we also recorded a write-down of $4.7 million of certain leasehold improvements, computer software and
hardware in the quarter ended April 30, 2002. The leasehold improvements write-down related to two research and development facilities, which will be closed in connection with our February 2002 restructuring plan. A write-down of $0.7 million was
recorded in the quarter ended April 30, 2001 and no write-downs of long-lived assets were recorded during the year ended April 30, 2000.





Note 6.    Restructuring Charges





Fiscal 2002





In February 2002, our Board of Directors approved a restructuring program to significantly reduce our operating expenses and to
further align the organization with current market conditions, future revenue expectations and our planned future product direction to focus on enabling organizations to protect, control and accelerate their web-enabled networks. This plan involved
the following steps:





| |  |  | Reducing our workforce by 200 employees, which represented approximately 45% of our workforce;
| | - |  | ----------------------------------------------------------------------------------------------




| |  |  | Closing and relocating two research and development facilities to the Sunnyvale, California headquarters location;
| | - |  | ------------------------------------------------------------------------------------------------------------------




| |  |  | Downsizing our international operations and discontinuing plans to fund additional international expansion (we will continue to manage current international
investments); and
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------




| |  |  | Canceling certain vendor contracts that existed prior to the restructuring and enhancing productivity in our operations in an effort to reduce costs.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------




In connection with this restructuring plan, we accrued approximately $12.9 million in the
fourth quarter ended April 30, 2002 relating to employee severance costs, facilities closure costs, lease abandonment costs and contract termination costs. All employees were notified of their termination prior to April 30, 2002. Estimates related
to sublease costs and income are 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 will be
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. As of April 30, 2002, substantially all severance
costs related to domestic employees had been paid and $10.5 million remained accrued for lease abandonment costs, contract termination costs and certain international employee severance costs. The lease abandonment costs will be paid over the
respective 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




48

CACHEFLOW, INC.





NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS(Continued)




better position us for 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 to
complete this effort, which included employee severance costs of approximately $1.7 million and certain contract termination costs of approximately $0.9 million. As of April 30, 2002, severance payments to domestic and international employees were
substantially completed, and of the $2.6 million restructuring charges, $2.3 million had been paid, leaving a remaining accrual of $0.3 million for contract termination fees on our balance sheet.





Fiscal 2001





In February 2001, our Board of Directors approved a restructuring program instituted in response to the economic slowdown that negatively impacted the demand for our products in the fourth quarter of fiscal year 2001, as potential
customers deferred spending on their Internet and intranet infrastructure. As part of the restructuring program, we implemented a reduction in workforce by 52 employees and incurred $1.9 million in restructuring charges, which included employee
severance costs of approximately $1.3 million and certain contract termination costs of approximately $0.6 million. At April 30, 2001, $0.9 million of $1.9 million in restructuring charges remained accrued. As of October 31, 2001, these severance
and contract termination payments were completed.





The following table sets forth an analysis of the
components of the fiscal 2001 and 2002 restructuring charges and payments made through April 30, 2002 (in thousands):

Note 7.    Stockholders Equity





Preferred Stock





Our Certificate of Incorporation authorizes 10,000,000 shares of preferred stock. The preferred stock is undesignated and the Board of Directors has the authority to issue new classes of preferred stock and determine the
rights, preferences and privileges of such preferred stock.





Common Stock





On November 19, 1999, we completed our initial public offering, in which we sold 5,750,000 shares of common stock (including an
over-allotment option of 750,000 shares) at $24 per share. Upon the closing of the offering, all of our preferred stock converted to common stock. Proceeds from the offering were approximately $126.5 million, net of underwriters discounts,
commissions and offering costs.





We have either assumed or have entered into Stock Purchase Agreements in
connection with the sale of common stock to employees, consultants and directors. We typically have the right to repurchase, at the original

issue price, a declining percentage of certain of the shares of common stock issued based on the employees, consultants, and directors service periods. The repurchase right generally declines on
a percentage basis over four years based on the length of each respective employees continued employment with us, and the directors membership on the Board of Directors under this agreement. As of April 30, 2002, 2001 and 2000, 610,408,
3,453,962 and 3,987,916 shares, respectively, of common stock issued under these agreements were subject to repurchase.





In September 1999, our Board of Directors approved an increase in authorized shares of common stock from 60,000,000 to 200,000,000 upon the completion of our initial public offering of our common stock.





Shares of Common Stock Reserved for Future Issuance

3,451Other option grants

20125,492





Notes Receivable from Stockholders





In June 2000 and December 2000, we assumed certain promissory notes in connection with our Entera and SpringBank acquisitions. The terms
of these notes range from three to four years and were provided to officers and employees of the acquired companies for the purchase of common stock. The notes are full-recourse and bear interest at rates between 5.54% and 6.69%. Each note and
related interest is secured by shares of common stock of the Company owned by each officer or employee. As of April 30, 2002, several of the notes have been paid in full.





Note 8.    Employee and Director Stock Plans





In 1996, we established the 1996 Stock Option Plan (the 1996 Plan) under which stock options may be granted to employees, directors and consultants of the Company and authorized 1,000,000 shares of common stock there under. Through
various amendments, the Board of Directors and stockholders approved the increase in the number of shares authorized for issuance under the 1996 Plan to 15,643,000. Under the 1996 Plan, nonstatutory stock options may be granted to employees and
consultants, and incentive stock options (ISO) may be granted only to employees. In the case of an ISO that is granted to an employee who, at the time of the grant of such option, owns stock representing more than 10% of the total combined voting
power of all classes of stock of the Company, the per share exercise price shall not be less than 110% of the fair market value per share on the date of grant or, granted to any other employee, the per share exercise price shall not be less than
100% of the fair value per share on the date of grant. The exercise price for non-qualified options may not be less than 85% of the fair value of common stock at the option grant date.





Options issued under the 1996 Plan are immediately exercisable, and shares issued upon exercise of an option are subject to a right of repurchase by us at the original
issuance price. The repurchase right lapses as




50

##### Table of Contents

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS(Continued)




determined by our Board of Directors, generally 25% after one year and 2.0833% per month thereafter. Options that expire and shares issued under the 1996 Plan that are repurchased become
available for issuance under our 1999 Stock Incentive Plan, which is discussed further below. No options may be granted under the 1996 Plan after September 24, 1999. Any option granted under the 1996 plan shall be exercisable at such times and under
such conditions as determined by our Board of Directors.





Stock Option Exchange Program





In February 2001, we announced a voluntary stock option exchange program for our employees. Under the program, certain
employees were offered the opportunity to cancel outstanding stock options previously granted to them in exchange for an equal number of new options to be granted at a future date, at least six months and a day after the cancellation date. Employees
electing not to participate in the exchange received an option grant equal to 25% of the number of their unexercised options that had exercise prices greater than $8 per share. The exercise price of these new options was equal to the fair market
value of our common stock on the date of grant. In connection with this program, 1,698,633 options were cancelled for those employees who elected to participate in the exchange and 1,553,863 options were granted to employees who elected not to
participate. The exchange program did not result in any additional compensation charges or variable plan accounting. Members of our Board of Directors and its officers and senior executives were not eligible to participate in this program.





In November 2000, we entered into a termination agreement with our departing chairman that provided for the
immediate vesting of certain unvested stock options upon the chairmans termination date. We recorded a non-recurring $28.1 million stock compensation charge equal to the difference between the strike price and the fair value of the underlying
stock on the date the stock option grant was modified, multiplied by the number of shares that were immediately vested.





We granted 677,380 options to one of our consultants on October 13, 1999 to purchase common stock at an exercise price of $4.00 per share. The options were immediately vested, nonforfeitable and exercisable and were subsequently
exercised. The fair value of the options was estimated using the Black-Scholes option pricing model with the following weighted average assumptions: risk free rate of 6.0%, expected life of the options of 0.05 years, 60% volatility and no dividend
yield. We calculated a value of approximately $8.1 million for the consultants options and recorded this amount as expense in October 1999.





Employee Stock Purchase Plan





In September 1999, our Board
of Directors adopted the Employee Stock Purchase Plan, or ESPP. The plan became effective upon the effective date of our initial public offering of our common stock. As of April 30, 2002, a total of 4,000,000 shares of common stock have been
reserved for issuance under the plan. Under the plan, eligible employees may purchase common stock through payroll deductions, which in any event may not exceed 15% of an employees compensation, at a price equal to the lower of 85% of the fair
market value of the common stock at the beginning of each offering period or at the end of each purchase period. The number of shares reserved under the Employee Stock Purchase Plan automatically increased by 500,000 shares beginning
January 31, 2000, and will continue to do so annually. Our Board of Directors, at its discretion, may reduce the automatic annual increase in reserved shares.





1999 Stock Incentive Plan





In
September 1999, our Board of Directors adopted the 1999 Stock Incentive Plan (the Incentive Plan). As of April 30, 2002, 16,793,287 shares of common stock have been reserved for issuance. The plan became




51




---

##### Table of Contents



CACHEFLOW, INC.





NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS(Continued)




effective upon the effective date of our initial public offering of its common stock. The number of shares reserved under the Incentive Plan automatically increased on January 1, 2002 by
2,000,000 shares and will increase on an annual basis by the lesser of 5% of the total amount of common stock outstanding or 2,000,000 shares. Furthermore, any 1996 Plan options that are cancelled or exercised and subsequently repurchased by us
become available for issuance under the Incentive Plan. The exercise price for incentive stock options and non-qualified stock options may not be less than 100% and 85%, respectively, of the fair market value of common stock on the option grant
date.





1999 Director Option Plan





In September 1999, our Board of Directors adopted the 1999 Director Option Plan (the Directors Plan). As of April 30, 2002, 700,000 shares of common stock
have been reserved for issuance. The Directors Plan became effective on the date of its adoption. Each non-employee director joining the Board of Directors following the effective date of the initial public offering will automatically receive
options to purchase 25,000 shares of common stock. In addition, each non-employee director will automatically receive options to purchase 5,000 shares of common stock at each annual meeting of the Board of Directors held in the year 2000 and
thereafter. Each option will have an exercise price equal to the fair market value of the common stock on the option grant date. The number of shares reserved under the Directors Plan automatically increased by 100,000 shares beginning
January 1, 2000 and will continue to do so annually. Our Board of Directors, at its discretion, may reduce the automatic annual increase in reserved shares.





2000 Supplemental Stock Option Plan





In February 2000, our
Board of Directors adopted the 2000 Supplemental Stock Option Plan (the 2000 Plan), under which 3,000,000 shares of common stock have been reserved for issuance. Employees and consultants are eligible to participate in the 2000 Plan, and
outside directors and executive officers are not eligible to participate. The 2000 Plan provides for the grant of nonstatutory stock options to purchase shares of our common stock and restricted shares of our common stock. The exercise price for
stock options issued under the 2000 Plan may not be less than 25% of the fair market value of common stock on the option grant date.





In February 2001, we granted 1,091,000 shares of restricted stock to employees as an employee retention bonus. These shares vest 50% on November 26, 2001 and another 50% on February 25, 2002. We recorded $6.4 million of
deferred stock compensation in connection with this transaction based on the intrinsic value of this stock award on the date of grant. This deferral will amortize to stock compensation expense on a straight-line basis over the 12-month vesting
period.

outstanding options of the acquired entity are assumed, or instances where certain modifications are made to the terms and conditions of option grants subsequent to the grant date). Stock compensation expense is recorded over the option vesting
period, generally two to four years, or immediately if there is no vesting period. We recorded stock compensation expense of $19.5 million, $69.2 million and $38.4 million, respectively, for the years ended April 30, 2002, 2001 and 2000,
respectively. At April 30, 2002 and 2001, we had $3.6 million and $33.3 million, respectively, of remaining unamortized deferred compensation. Such amounts are included as a reduction of stockholders equity and are being amortized using a
graded method over the vesting period of each respective option.





Pro Forma Disclosures of the Effect of
Stock-Based Compensation





Pro forma information regarding results of operations and net loss per share is
required by FAS 123, which also requires that the information be determined as if we had accounted for our stock-based awards to employees under the fair value method of FAS 123. The fair value for each stock-based award was estimated at the date of
grant using the Black-Scholes option pricing model for the year ended April 30, 2002, 2001 and 2000 with the following weighted-average assumptions:

The option valuation models were developed for use in the
estimation of the fair value of traded options that have no vesting restrictions and are fully transferable. In addition, option valuation models require the input of highly subjective assumptions, including the expected life of the option. Because
our employee stock-based awards have characteristics significantly different from those of traded options, and because changes in the subjective input assumptions can materially affect the fair value estimate, in managements opinion, the
existing models do not necessarily provide a reliable single measure of the fair value of its employee stock-based awards.





For purposes of pro forma disclosures, the estimated fair value of stock-based awards to employees is amortized to pro forma expense over the vesting period for stock options and over the six-month purchase period for stock purchases
under the ESPP. Pro forma information follows (in thousands, except per share amounts):

issued under our ESPP was $1.40, $20.03 and $17.36 per share for the years ended April 30, 2002, 2001 and 2000 (the year the ESPP was adopted).

The provision for income taxes of $0.5 million, $0.3 million and $0.1 million for the years ended April 30, 2002, 2001 and 2000,
respectively, is composed entirely of foreign corporate income taxes. A reconciliation of the income tax provision to the amount computed by applying the statutory federal income tax rate to income (loss) before income tax provision is summarized as

Deferred income taxes reflect the net tax effects of temporary
differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Certain reclassifications have been made to prior year balances in order to conform with the current
year presentation. Significant components of our deferred tax assets are as follows (in thousands):

We have incurred losses from inception through fiscal 2002.
Management believes that, based on the history of such losses and other factors, the weight of available evidence indicates that it is more likely than not that we will not be able to realize our deferred tax assets and thus a full valuation
allowance has been recorded at April 30, 2002 and 2001. The valuation allowance increased by $59.8 million, $43.7 million and $15.3 million during fiscal years 2002, 2001 and 2000, respectively.





As of April 30, 2002, we had net operating loss carry forwards for federal income tax purposes of approximately $206.6 million, which will expire in fiscal years
ending in 2011 through 2022, if not utilized. We also had net operating loss carry forwards for state income tax purposes of approximately $100.7 million, which




55

##### Table of Contents

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS(Continued)




expire beginning in fiscal years ending in 2007, if not utilized. We also had federal and California research and other tax credit carry forwards of approximately $2.6 million, which will expire
in fiscal years 2012 through 2022, if not utilized.





Utilization of our net operating loss and credit carry
forwards may be subject to substantial annual limitation due to the ownership change limitations provided by the Internal Revenue Code and similar state provisions. Such an annual limitation could result in the expiration of the net operating loss
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 years period.





Our net operating loss carry forwards, which have been offset by the valuation allowance, include deferred tax benefits associated with
employee incentive stock options. These deferred tax benefits of approximately $27.4 million will be credited to additional paid-in-capital when realized.





Note 10.    Defined Contribution Benefit Plan





We have a
defined contribution benefit plan under Section 401(k) of the Internal Revenue Code, which covers substantially all United States-based employees. Eligible employees may contribute pre-tax amounts to the plan via payroll withholdings, subject to
certain limitations. We do not match contributions by plan participants.





Note 11.    Lease Commitments





We lease certain facilities and equipment under noncancelable operating leases. Certain of our facility
leases provide for periodic rent increases based on the general rate of inflation. Future minimum lease payments under operating leases are as follows (in thousands):

Rent expense for the three years ended April 30, 2002, 2001 and
2000 was $6.2 million, $5.3 million and $2.3 million, respectively.





In October 2000, we entered into a short-term
lease agreement for a 42,000 square foot research and development facility in Sunnyvale, California with the intention of negotiating a longer-term lease, which would include additional facilities to house other corporate functions. The lease term
commenced upon possession in November 2000 and was extended through July 31, 2001. In early 2001, in response to a downturn in the economy, we restructured our operations, declined to negotiate a longer-term lease for additional facilities, and made
efforts to relocate our California research and development activities.





In March 2001, we executed a new, five
year operating lease for a 46,000 square foot research and development facility in Sunnyvale, California. The lease commencement occurred in July 2001, and will extend




56

##### Table of Contents



CACHEFLOW, INC.





NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS(Continued)




for a term of five years from the commencement date. Lease payments escalate annually and the total future minimum lease payments amount to $11.5 million over the lease term. As part of this
agreement, we are required to maintain on deposit with a major financial institution an irrevocable standby letter of credit as a form of security totaling $1.9 million which is classified as restricted investments in the long-term
assets section of the balance sheet as of April 30, 2002. The letter of credit expires on April 1, 2002 but will automatically extend to each succeeding calendar year, up to June 30, 2006, unless otherwise terminated in writing.





Note 12.    Related Party Transaction





In April 2001, we entered into a series of agreements with Loudcloud, Inc. (Loudcloud), a managed services provider, whose chairman of the board and co-founder
also serves as a CacheFlow director. Pursuant to one agreement, CacheFlow will outsource the management of its Internet-based applications to Loudcloud on an annual subscription basis totaling approximately $0.7 million. Under a separate agreement,
Loudcloud will purchase CacheFlows caching appliance products for use in its managed services operations and will begin offering caching services to its customers. A third alliance agreement provides that Loudcloud will pay CacheFlow for
customer referrals forwarded to Loudcloud. In March 2002, we and Loudcloud agreed to terminate the outsource agreements with a $0.4 million cancellation fee from us to Loudcloud.





Note 13.    Litigation





In June and
July 2001, a series of putative securities class actions were filed on behalf of persons who purchased our stock between November 18, 1999 and June 8, 2001 in the U.S. District Court for the Southern District of New York. These cases have been
consolidated under the case captioned Colbert Birnet, LP v. CacheFlow, Inc., et al., Civil Action No. 1-01-CV-5143. The complaints generally allege that various investment bank underwriters engaged in improper and undisclosed activities related to
the allocation of shares in our initial public offering of securities and maintained artificially high after-market prices. The complaints seek unspecified damages against the underwriters, our company, and certain of our current and former
directors and officers. 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 offerings. 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 are collectively captioned In re Initial Public Offering Securities Litigation Civil Action No. 21-MC-92. We intend to defend
against the allegations in the complaints vigorously and we believe the outcome would not have a material adverse effect on the business, results of operations, or financial condition of the Company.





On August 1, 2001, Network Caching Technology L.L.C. filed suit against CacheFlow 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.





From time to time and in the ordinary course of business, we may be subject to various other claims, charges and litigation. In
the opinion of management, final judgments from such other pending claims, charges

and litigation, if any, against us would not have a material adverse effect on our business, results of operations, or financial condition.





Note 14.    Geographic Information Reporting





We operate in one segment to design, develop, market and support web security appliances. Total export revenue consisted of sales from our U.S. operations to non-affiliated customers in other geographic regions. Sales
between geographic areas are accounted for at prices that provide a profit, and are in accordance with the rules and regulations of the respective governing authorities. During fiscal 2002, 2001 and 2000, there were no intra-enterprise sales, and no
material long-lived assets were located in our foreign operations during fiscal 2002, 2001 or 2000.

Note 16.    Subsequent Event





Our stock is currently traded on the Nasdaq National Market. Under Nasdaqs listing maintenance standards, if the closing bid price
of a companys common stock remains under $1.00 per share for 30 consecutive trading days, Nasdaq will issue a deficiency notice to that company. If the closing bid price does not reach at least $1.00 per share for a minimum of ten consecutive
trading days during the 90 calendar days following the issuance of the deficiency notice from Nasdaq, Nasdaq may de-list that companys common stock from trading on the Nasdaq National Market. On May 10, 2002 we received a notice from Nasdaq
stating that we were not in compliance with Nasdaqs continued listing requirements because the minimum closing bid price per




58




---

##### Table of Contents

share of our Common Stock had remained below $1.00 for 30 consecutive trading days. The letter further stated that the closing bid price of our common stock must be at least $1.00 per share for
ten consecutive trading days during the 90-day period subsequent to May 10, 2002, or Nasdaq will delist our common stock from trading on the Nasdaq National Market on or about August 8, 2002. We expect to receive notice from Nasdaq that the failure
of our Common Stock to maintain Nasdaqs minimum closing bid price requirement of $1.00 has continued beyond the 90 day probationary period allowed under the Nasdaq National Marketplace Rules and, therefore, our Common Stock may be delisted. We
intend to appeal any such delisting decision, and the delisting could be stayed pending a hearing before the Nasdaq Qualifications Panel.





Furthermore, at the discretion of our Board of Directors, we intend to effect a reverse split of our common stock in order to attempt to regain compliance and continue to trade on the Nasdaq National Market. On July 15,
2002, the Board of Directors unanimously adopted a resolution approving and recommending to the stockholders for their approval an amendment to our Amended and Restated Certificate of Incorporation to effect a reverse split of our outstanding shares
of common stock, in a ratio of either one-for-five, one-for-ten or one-for-fifteen, which ratio (assuming such ratio has been approved by our stockholders) will be chosen by the Board of Directors at any time prior to the date that is ninety days
after our 2002 Annual Meeting of Stockholders. Our stockholders are being asked at the Annual Meeting to act upon a proposal to authorize the Board of Directors to file an amendment to our Amended and Restated Certificate of Incorporation and
thereby effect such a reverse stock split by voting in favor of each of the three proposed amendments. Assuming that our stockholders approve one or more of the proposed amendments, the Board of Directors will then choose one amendment from among
the approved amendments, and will effect the reverse stock split in that approved ratio. If one or more of the proposed reverse stock split amendments is approved by our stockholders, the Board of Directors intends to subsequently effect, in its
sole discretion, the reverse stock split based upon any of the following ratios: one-for-five, one-for-ten or one-for-fifteen, provided such ratio has been approved by our stockholders. The Board of Directors determination of the applicable
ratio will be made with the primary purpose of retaining our Nasdaq National Market listing and the liquidity of our common stock.

To the Board of Directors and Stockholders


CacheFlow Inc.





We have audited the accompanying consolidated balance sheets of CacheFlow Inc. as of April 30, 2002 and 2001, and the related consolidated statements of operations, stockholders equity and cash

management. Our responsibility is to express an opinion on these financial statements and schedule based on our audits.





We conducted our audits in accordance with auditing standards generally accepted in the United States. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements
are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.





In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of CacheFlow Inc. at April 30, 2002 and 2001, and the
consolidated results of its operations and their cash flows for each of the three years in the period ended April 30, 2002, in conformity with accounting principles generally accepted in the United States. Also, in our opinion, the related financial
statement schedule, when considered in relation to the basic financial statements taken as a whole, presents fairly in all material respects, the information set forth therein.
