Description of Business

      F5 Networks provides integrated products and services to manage, control and optimize Internet traffic and content. Our five core products, the BIG-IP® IP Application Switch & Controller, 3-DNS® Controller, GLOBAL-SITE™ Controller, EDGE-FX® Cache, and the SEE-IT™ Network Manager, help manage traffic and content to servers and network devices in a way that maximizes availability and throughput. Our unique iControl™ Architecture integrates our products together and also allows our customers to integrate them with other third party products. Our solutions address many elements required for successful Internet and Intranet business applications, including high availability, high performance, intelligent load balancing, fault tolerance, security, streamlined manageability, and global data management and content control. By enhancing Internet performance availability and content distribution, our solutions enable our customers and partners to maximize the use of the Internet in their business.

Industry Background

      Significant growth in the number of Internet users coupled with the increased availability of powerful new tools and equipment that enable the development, processing and distribution of data across the Internet, has led to a proliferation of Internet-based applications and services, such as e-commerce, e-mail, electronic file transfers and online interactive applications. Recently, increases in the number of Internet users, the use of broadband service, the number of Web sites using sophisticated business applications and the richness of Internet content itself, together with unpredictable traffic, have increased the complexity of Internet service delivery and strained network infrastructures.

      An increasing number of businesses rely on the Internet as a fundamental commerce and communication tool. Failure of these businesses to deliver expected availability and performance for their Internet-based applications can result in a significant cost to the organization.

      To support the dramatic increases in Internet traffic and complexity, many organizations have aggressively expanded network server capacity. In this environment, organizations often deploy multiple servers in a group, or array, which contains individual application-specific servers or redundant servers that operate together as a virtual large server. Server arrays can reduce single points of failure and be a cost-effective way to increase the potential capacity of the system by providing the flexibility to add additional servers to the array as needed. The practice of deploying server arrays in geographically dispersed sites to help prevent system failure and direct traffic more efficiently is also a growing trend.

      Along with their benefits, server arrays and geographically dispersed sites have increased the need for intelligent traffic and content management devices to optimize server availability and performance. Intelligent traffic management devices identify which server, whether local or remote, is best able to handle user requests. They also read and interpret user requests and route those requests to the most responsive server or to servers

Table of Contents

or arrays that have been designated to handle specific types of requests. Content management devices include controllers that replicate published content to ensure that it is uniformly available on all servers in a network. Cache servers increase access to content by capturing and storing content at one or more points between network servers and users.

      Currently, many available Internet traffic and content management products are extensions of hardware-based switches, which lack the robust functionality required to manage the increasing complexity of requests and responses that characterize business activity on the Internet. These products are typically not designed to address application availability, nor do they meet the manageability and scalability required by organizations that depend on the Internet as a fundamental commerce and communications tool. As a result, we believe they do not measure up to the demands of today’s rapidly changing Internet environment.

F5 Solution

      F5 is a leading innovator for Internet and e-Business optimization and automation. We believe our products deliver the secure and high-performance Internet traffic and content infrastructure businesses need to succeed.

      Our intelligent traffic management products monitor and manage locally and geographically dispersed servers, and intelligently direct traffic to the server best able to handle the user request. Our content management products help ensure new and updated content is replicated uniformly across all servers and is readily accessible to all users. As components of our integrated iControl Architecture, our solutions ensure Internet quality control by providing the following key benefits:

      High system availability. Our integrated suite of products works with servers deployed in a redundant server array over a local or wide area network to enhance network performance and reduce single points of failure. Our traffic management products continuously monitor network performance to enable real-time detection of server, application and content degradation or failure. Based on this information, our solutions automatically direct user requests to functioning servers and applications. Our products also enable network administrators to deploy new servers and take individual servers offline for routine maintenance without disrupting service to end users.

      Increased performance. Our products provide a significant performance improvement over other current approaches. Our traffic and content management products monitor server and application response time and verify content. This information is used to intelligently direct user requests to the server with the fastest response time. They also read and interpret individual requests and can direct those requests to specific servers, arrays or sites based on predetermined rules defined by network managers. As a complement to these products, our cache servers improve performance by capturing and storing content at points between network servers and end-users, where content can be accessed more quickly. By intelligently directing traffic throughout the network, our solutions reduce server overload conditions that may cause performance degradation.

      Cost-effective scalability. Our solutions enable more efficient utilization of existing server capacity by intelligently directing traffic among servers. This capability allows organizations to optimize the capacity of existing servers and, as traffic volume dictates, cost-effectively expand server capacity through incremental additions of relatively low cost servers rather than upgrading to larger, more expensive servers. Our solutions can be used with multiple heterogeneous hardware platforms, allowing organizations to protect their investments in their legacy hardware installations as well as integrate future hardware investments. In addition, strategic deployment of our cache products can reduce the load on network servers and minimize the need to add more expensive production server capacity.

      Easier network manageability. Our products collect information that can be used to facilitate network management and planning from a central location. Leveraging our products’ strategic location in the network, our solutions collect data that is crucial for traffic analysis and apply proprietary trend and analysis tools that synthesize this data so that network managers can forecast network requirements more accurately. In addition,

our products automatically synchronize content across remote locations, helping to ensure users access to the same content regardless of server location.

      Enhanced network control. Our solutions enable organizations to prioritize and arrange network traffic based on specific rules defined by network managers. For example, our products may be configured to direct traffic over the most cost-efficient communication links or, alternatively, to deliver the most rapid response to requests.

Strategy

      Our objective is to be the leading provider of integrated Internet traffic and content management solutions designed to optimize network availability and performance. Key components of our strategy to achieve this objective include:

      Offer complete secure Internet traffic and content management solutions. We plan to continue expanding our existing suite of products to provide complete Internet traffic and content management solutions. We also intend to continue investing in our professional services group to provide the installation, training and support services required to help our customers optimize their use of our integrated traffic and content management products.

      Invest in technology to continue to meet customer needs.

We intend to maintain our level of investment in research and development to provide our customers with complete secure Internet traffic and content management solutions that meet their needs.

      Expand sales channels and geographic scope of sales. We plan to continue to invest in the expansion of our sales channels. In addition to maintaining a strong direct sales force, we intend to further expand our indirect sales channels through leading industry resellers, original equipment manufacturers, systems integrators, Internet service providers and other channel partners. We are also seeking to aggressively develope our international sales capabilities, particularly in selected countries in the European and Asia Pacific markets.

      Build and expand relationships with strategic partners. We capitalize on products, technologies and channels that may be available through partners. We currently have OEM relationships with Dell Computer Corporation, Nokia and Enterasys Networks. In addition, we have created significant go-to-market relationships with key independent software vendors (ISV’s) such as Microsoft, Oracle, and BEA through our iControl Architecture which enables these partners to incorporate programmatic interfaces to our Internet and content management products in their software programs. We plan to continue to seek relationships with partners that will enable us to increase the market opportunity for our products and technologies.

      Leverage our market leadership to continue to build the F5 brand. We intend to continue building brand awareness that positions us as one of the leading providers of intelligent Internet traffic and content management solutions. Our goal is for the F5 brand to be synonymous with superior network performance, high quality customer service and ease of use. To achieve these objectives, we plan to continue using a broad range of marketing programs, including active tradeshow participation, advertising in print publications, direct marketing, high-profile Web events, our Internet site and joint partner marketing programs.

      IControl API. IControl is an API (application program interface) that offers a complete and cohesive architectural solution for the distribution, delivery, and control of both content and applications. All of our products are designed to be iControl enabled. IControl integrates our products together and also allows integration with third party products. This architecture allows network managers to configure all components in a network infrastructure through a single policy that can be centrally managed. Our most recent version supports two different transport protocols (COBRA and SOAP) to meet the needs of different types of businesses.

      EDGE-FX Cache. EDGE-FX is a leading Internet cache server that can be deployed as a standalone device or integrated with our other products. EDGE-FX consists of software loaded on a pre-configured, industry standard hardware platform. EDGE-FX accelerates access to Web content by storing frequently requested data at strategic points in a computer network, making it quickly available to Internet users. As a standalone device, EDGE-FX may be installed in virtually any network infrastructure. Integrated with our

Table of Contents

other traffic and content management products, EDGE-FX enables customers to implement end-to-end content delivery solutions and build their own content delivery networks.

      EDGE-FX also supports a streaming media extention option, which enables support for Real Networks, Microsoft Windows Media or Apple/ Quicktime media types. This option enables the device to provide live or on-demand serving of streaming media. As a media enabled cache product, EDGE-FX is a strategic component in the roll out of private content distribution networks to enterprise customers. EDGE-FX helps enable applications such as corporate communications, travel-less training and other content based uses of the network.

      EDGE-FX supports several flexible deployment options to conserve bandwidth and server resources while accelerating content to Internet users.

  •  Forward Proxy or Transparent Proxy. EDGE-FX can be deployed in front of Web browsers for internal user access. EDGE-FX can be positioned as a forward proxy cache, making it valuable for enterprise Intranets. Instead of sending requests for Web content directly to the origin server, browsers are configured to send requests directly to the cache thereby reducing bandwidth utilization costs.
 
  •  Reverse Proxy. When deployed in front of Web servers for external user access, EDGE-FX offloads client requests from the Web server, eliminating the danger of server traffic surges and reducing the number or size of servers required.

  Designed for massive scalability, multiple EDGE-FX caches can be managed with the BIG-IP Cache Controller to enable cache farm load balancing, replication of content across multiple caches, and Layer 7 management of cached objects.

      GLOBAL-SITE Controller. GLOBAL-SITE, a content delivery appliance, has been designed to help organizations automate the distribution and synchronization of content and applications to local and geographically dispersed sites. GLOBAL-SITE was developed to work with our other products to intelligently deploy both program and data files to arrays of heterogeneous servers as well as the EDGE-FX Cache. GLOBAL-SITE consists of our proprietary software which is loaded on a pre-configured, industry-standard hardware platform. GLOBAL-SITE’s configuration database allows administrators to define standard rules for content deployment as well as accommodate unique content distribution events as needed.

      SEE-IT Network Manager. SEE-IT is a software application based on F5’s iControl that communicates with F5 products to help improve the management and functionality of an organization’s network, thereby driving down the total cost of ownership. SEE-IT uses data collected by F5 products to perform monitoring of the F5 appliances, as well as crucial traffic analysis management functions. By reviewing historical patterns, network administrators can build predictive models and forecast usage, which helps them to intelligently plan and budget for additional server and bandwidth capacity. SEE-IT consists of the following capabilities:

  •  Real-time monitoring that displays key data on network traffic in easy-to-read graphical illustrations, thereby enabling network administrators to quickly obtain information regarding network and server performance, including data about server status and traffic, number of connections, active and inactive IP addresses and the availability of individual applications.
 
  •  Forward-looking trend and analysis tools that use the information generated by F5’s products to project future network and server needs. Network managers and system administrators can use these

6


Table of Contents

  tools to create “what if?” scenarios to help forecast the need for additional servers, interface upgrades and other network capacity requirements.
 
  •  Configuration management allows users to assure that configurations and policies are implemented on each of the F5 devices. Users can simply and confidently deploy configuration or policy updates to respond to the data obtained through the monitoring capabilities.
 
  •  Application level views simplifies the task of understanding the purpose of each piece of networking gear that is deployed. SEE-IT allows users to “organize” the F5 gear to view the network based on the application they are meant to support.

      3-DNS Controller.     3-DNS is an intelligent wide area traffic management appliance that manages and distributes user requests across wide area networks. 3-DNS consists of our proprietary software, which we load on a pre-configured, industry-standard hardware platform. Like BIG-IP, 3-DNS functions with multiple heterogeneous hardware platforms and supports a wide variety of network protocols, including Web, e-mail, audio, video, database and file transfer protocol, and manages traffic for network devices such as firewalls, cache servers and multimedia servers.

      When an end-user request is received from a local domain name server or DNS, 3-DNS collects network information and communicates with each site in the network to determine the site with the fastest response time. 3-DNS, integrated with BIG-IP, sends the request to the BIG-IP at the site. BIG-IP then directs the request to the individual server best able to handle it. Although organizations can deploy a single 3-DNS in their network configuration, multiple 3-DNS Controllers are often deployed within the network to provide redundancy to help ensure network availability and performance for end users. Additional 3-DNS features include:

  •  Dynamic load balancing optimizes use of available network resources across wide area networks.
 
  •  User-defined production rules allow organizations to pre-configure traffic distribution decisions according to their specific user requirements.
 
  •  Secure server protection offers security features for wide area networks similar to those BIG-IP provides for local area networks.

      BIG-IP Controller. BIG-IP is an intelligent local traffic management appliance consisting of our proprietary software on a pre-configured, industry-standard hardware platform. Situated between a network’s routers and server array, BIG-IP continuously monitors the array of local servers to ensure application availability and performance and automatically directs user requests to the server best able to handle these requests. By quickly detecting application and server failures, and directing service toward those servers and applications that are functioning properly, BIG-IP is designed to shield users from system failures and provide timely responses to user requests and data flow. BIG-IP offers a comprehensive selection of load balancing algorithms that lets network managers choose a load balancing configuration that best suits their organization’s particular needs. In addition, BIG-IP actively queries and checks content received from applications. If a server and application are responding to users’ requests with incorrect content, BIG-IP redirects requests to those servers and applications that are responding properly, thereby helping to ensure the quality of content.

      BIG-IP is compatible with any system that uses the standard Internet communication protocol or IP, and can operate with multiple, heterogeneous hardware platforms. This enables organizations to leverage their existing infrastructure without limiting their options to meet future network needs. BIG-IP supports a wide variety of network protocols, including Web, e-mail, audio, video, database and file transfer protocol. BIG-IP also manages traffic for network devices such as firewalls that prevent unauthorized access to a network system, cache servers that store frequently accessed Web content and multimedia servers. BIG-IP’s ability to intelligently distribute traffic across server arrays reduces the need for increasingly larger and more expensive servers to accommodate increases in network traffic. This configuration also reduces the single point of failure inherent with a single large server and allows for the orderly addition of new servers or the routine maintenance or upgrades of servers without disrupting service to the end user.

Table of Contents

      BIG-IP’s unique Layer 7 switching capability enables the successful delivery of business-critical applications with 24/7 availability, scalability, and high performance. Examining traffic at Layer 7 allows intelligent quality of service (QoS) through routing and management decisions made based on application information. BIG-IP enables the use of all of its Layer 7 features simultaneously without imposing limitations on the length of the URL, cookie, or location of the cookie – providing intelligent, granular management of web sites without performance degradation. Additional BIG-IP features include:

  •  Infrastructure Security — BIG-IP provides an additional layer of security protecting against unauthorized access of the network.
 
  •  Application Security — BIG-IP can be configured to deny any file-based attack like “codered” in a matter of seconds, limiting exposure to an attack.
 
  •  Web Acceleration — BIG-IP enables servers to support more user requests, thus helping businesses cost effectively scale their Web infrastructure.
 
  •  Secure Application Acceleration — Secure sockets layer (SSL) as a means for securing applications has moved off the Web server and onto BIG-IP as a standard deployment practice. F5 will soon offer a higher level of security via its BIG-IP FIPS.
 
  •  BIG-IP FIPS — hardware option and Controller products extend SSL processing capabilities into a specific niche of customers that are either required by law (government agencies) or have adopted on their own accord (financial and health care institutions) FIPS-based products. BIG-IP is the only Internet traffic management product that supports an integrated FIPS 140-1 Level 3 solution.
 
  •  Session Persistence enables server arrays to support e-commerce and other applications by allowing users to re-establish a secure connection with a specific server to complete an unfinished transaction.
 
  •  Quality of Service — Rate shaping allows priority levels to be assigned to specific types of traffic ensuring a quality user experience.
 
  •  Packet filtering enables content providers to direct network traffic to servers based on criteria set by network managers to ensure networks are being used efficiently.

Prior to the installation of our Internet traffic and content management solutions, our professional services team works with organizations to analyze and understand their special network needs. They also make recommendations on how to integrate our solutions to best utilize our product features and functionality to support their unique network environment. Once our customers purchase our products, we offer on-site installation and training services to help our customers make use of the functionality built into our products. The installation process generally occurs within 30 days of product shipment to the customer.

      Our technical support team assists our customers with online updates and upgrades and provides remote support through a 24x7 help desk. We also offer seminars and training classes for our customers on the configuration and use of our products, including local and wide area network system administration and management. In addition, we provide a full range of consulting services to our customers, including comprehensive network management, documentation and performance analysis and capacity planning to assist in predicting future network requirements.

Manufacturing

      We outsource the manufacturing of our pre-configured, industry-standard hardware platforms to several contract manufacturers, who assemble these hardware platforms to our specifications. These platforms consist primarily of an Intel-based computing platform, rack-mounted enclosure system and custom-designed front panel. We install our proprietary software onto the hardware platforms and conduct functionality testing,

quality assurance and documentation control prior to shipping our products. Subcontractors supply our contract manufacturers with the standard parts and components for our products, which consist primarily of motherboards, reboot cards and chassis for our products, although recently we have begun to stock certain key components. Generally purchase commitments with our limited source suppliers are on a purchase order basis.

Competition

      Our markets are new, rapidly evolving and highly competitive, and we expect this competition to persist and intensify in the future. We compete in the Internet traffic and content management market primarily on the basis of product price/performance, features, service, and warranty. Our principal competitors in the Internet traffic and content management market include CacheFlow, Cisco Systems, Extreme Networks, Foundry Networks, Network Appliance, Nortel Networks and Radware.

      Cisco Systems has a product offering similar to ours and holds the dominant share of the market. Cisco has a longer operating history and significantly greater financial, technical, marketing and other resources than we do. Cisco also has a more extensive customer base and broader customer relationships including relationships with many of our current and potential customers that could be leveraged. In addition, Cisco has large, well established, worldwide customer support and professional services organizations and a more extensive direct sales force and sales channels than we do. Cisco and our other competitors may be able to respond more quickly to new or emerging technologies and changes in customer requirements than we can. There is also the possibility that these companies may adopt aggressive pricing policies to gain market share. As a result, these companies pose a serious competitive threat that could undermine our ability to win new customers and maintain our existing customer base. Nevertheless, we believe these threats are mitigated by differences between the functionality, performance and integration of our products and those of our competitors, including Cisco.

Intellectual Property

      We rely on a combination of copyright, trademark and trade secret laws and restrictions on disclosure to protect our intellectual property rights. We currently do not have any issued patents but have nine applications pending for various aspects of our technology. We also enter into confidentiality or license agreements with our employees, consultants and corporate partners, and control access to, and distribution of, our software, documentation and other proprietary information. However, despite our efforts to protect our proprietary rights, unauthorized parties may attempt to copy or otherwise obtain and use our products or technology.

      We incorporate software that is licensed from several third party sources into our products. These licenses generally renew automatically on an annual basis. We believe that alternative technologies for this licensed software are available both domestically and internationally.

Employees

      As of September 30, 2001, we employed 490 full-time persons, including 122 in product development, 165 in sales and marketing, 121 in professional services and technical support and 82 in finance, administration and operations.

      None of our employees are represented by a labor union. We have experienced no work stoppages and believe that our employee relations are good.

We also lease office space for our field personnel in Eastern Washington, California, New Jersey, Washington DC, Virginia, Hong Kong, Singapore, Thailand, Taiwan, Japan, Korea, Australia, India and the United Kingdom. We currently have surplus office space of approximately 14,000 square feet which we have subleased until 2003 and approximately 110,000 square feet which we have subleased until 2012.

Item 3.     Legal Proceedings.

      On August 8, 2001 a putative securities class action, captioned Atlas v. F5 Networks, Inc. et al., Civil Action No. 01-CV-7342, was filed in the United States District Court for the Southern District of New York against the firms that underwrote our initial public offering, F5 Networks, and several of our officers and directors. The complaint alleges violations of Sections 11 and 15 of the Securities Act of 1933 and Section 10(b) and Rule 10b-5 promulgated thereunder and Section 20(a) of the Securities Exchange Act of 1934 by F5 Networks and its officers and directors, and seeks unspecified damages on behalf of a purported class that purchased F5 Networks’ common stock between June 4, 1999 and December 6, 2000.

      On August 15, 2001 a similar complaint, captioned Lee v. F5 Networks, Inc. et al., Civil Action No. 01-CV-7625, was filed in the United States District Court for the Southern District of New York. The

13


Table of Contents

complaint is substantially identical to the Atlas complaint: it names the same defendants, contains the virtually identical claims, and seeks unspecified damages on behalf of a purported class of purchasers of common stock during an identical class period.

      Various plaintiffs have filed similar actions in the United States District Court for the Southern District of New York asserting virtually identical allegations against more than 200 other issuers. These cases have all been assigned to the Hon. Shira A. Scheindlin for coordination and decisions on pretrial motions, discovery, and related matters other than trial. We believe that we have meritorious defenses to the lawsuits and will defend ourselves vigorously in the litigation. An unfavorable resolution of the actions could have a material, adverse effect on our business, results of operations or financial condition.

      We are not aware of any additional pending legal proceedings against us that, individually or in the aggregate, would have a material adverse effect on our business, operating results, or financial condition. We may in the future be party to litigation arising in the course of our business, including claims that we allegedly infringe third-party trademarks and other intellectual property rights. Such claims, even if not meritorious, could result in the expenditure of significant financial and managerial resources.

Item 4.     Submission of Matters to a Vote of Securities Holders.

      No matters were submitted to a vote of shareholders during the fourth quarter of our fiscal year.

      Our policy has been to reinvest earnings to fund future growth. Accordingly, we have not paid dividends and do not anticipate declaring dividends on our common stock in the foreseeable future.

Recent Sales of Unregistered Securities

      On June 26, 2001, we entered into a Common Stock and Warrant Purchase Agreement with Nokia Finance International B.V. (“NFI”). Under this Agreement, we issued and sold to NFI (i) 2,466,421 shares of common stock and (ii) warrants (the “Warrants”) to purchase additional shares of common stock. We received total proceeds of $34.9 million, net of $1.8 million in estimated issuance costs from the sale of these shares and the Warrants. The Warrants allow NFI to purchase additional shares of common stock to increase

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

      The following Management’s Discussion and Analysis of Financial Condition and Results of Operations should be read in conjunction with our Financial Statements and Notes

Results of Operations

     Overview

      Total net revenues declined 1% in fiscal 2001 from fiscal 2000, compared to an increase of 290% in fiscal 2000 from fiscal 1999. The decrease in fiscal 2001 was primarily due to lower product sales as a result of a downturn in the US economy in fiscal 2001. Our reduced product sales were partially offset by an increase in service revenues resulting from maintenance renewals for our installed base of products. The increase in fiscal 2000 revenues was due to an expansion of indirect sales programs and an increase in our installed base service revenues.

      International revenues represented 33%, 19%, and 8% of total sales in fiscal 2001, 2000, and 1999, respectively. Fiscal 2001 was the first complete fiscal year for which we had subsidiaries in the Asia Pacific region which contributed to the increase in our international sales. We plan to continue to make significant investments in our international operations, particularly in the European and Asia Pacific markets. International revenues are expected to continue to represent a significant portion of our net revenues, although we cannot be assured that these revenues as a percentage of net revenues will remain at their current levels.

      Revenues from the sale of our products and software licenses are recognized, net of allowances for estimated returns, when the product has been shipped and the customer is obligated to pay for the product. Estimated sales returns are based on historical experience by product and are recorded at the time revenues are recognized. Services revenue for installation is recognized when the product has been installed at the customer’s site. Revenues for customer support are recognized on a straight-line basis over the service contract term. Consulting services are customarily billed at fixed rates, plus out-of-pocket expenses, and revenues from consulting services are recognized at the end of the quarter in which they are performed.

      Sales of BIG-IP represented 64%, 62%, and 73% of total net revenues in fiscal 2001, 2000, and 1999, respectively, and we expect to derive a significant portion of our net revenues from sales of BIG-IP in the future. During fiscal 2001 no single reseller or customer exceeded 10% of net revenue or our accounts receivable balance. During fiscal 2000 and 1999, one of our resellers, Exodus Communications, accounted for 14% and 22% of net revenue and 8% and 16% of our accounts receivable balance, respectively. In association with Exodus filing Chapter 11 bankruptcy, we recorded a non-recurring adjustment to our bad-debt expense of $1.75 million and a charge of $226,000 in cost of goods sold related to anticipated inventory lease payments not received by Exodus during fiscal 2001.

      Total cost of net revenues, as a percentage of total revenues, increased to 42.4% in fiscal 2001 from 30.0% in fiscal 2000 and 25.9% in fiscal 1999. The increase in fiscal 2001, compared to the prior year, relates to a non-recurring inventory reserve charge, costs associated with platform changes, a decrease in average selling price as a result of a change in product mix and an increase in personnel costs. The increase in fiscal 2000 was the result of higher production costs associated with hardware configuration enhancements and increased personnel costs, including training and consulting.

      Total operating expenses were $90.6 million, $63.2 million, and $25.5 million in fiscal 2001, 2000, and 1999, respectively. The 43.3% increase in total operating expense in fiscal 2001, compared to the prior year, is primarily the result of our continued investment in international operations, additional personnel costs, facilities costs, an increase in bad debt as a result of our relationship with Exodus and non-recurring restructuring charges. The 147.9% increase in operating expense in fiscal 2000, compared to the prior year, is primarily a result of an increase in total headcount to 496 from 187 at the end of fiscal 1999.

      Net revenues. Net revenues consist of sales of our products, which include software licenses, and services. Services include revenue from installation, service and support agreements provided as part of the initial product sale, sales of extended service and support contracts, and training.

      Product revenues. Product revenues were $78.6 million for the fiscal year ended September 30, 2001 compared to $88.0 million for the year ended September 30, 2000 and $23.4 million for the year ended September 30, 1999. The 10.6% decrease in fiscal year 2001 was primarily the result of reduced demand for our products in the US due to a general slow down in the US economy. Product revenues for fiscal year 2000 increased 275.7% from the prior year as a result of an expansion in indirect sales programs and a higher volume of unit sales from the direct sales force.

      Service revenues. Service revenues were $28.7 million for the fiscal year ended September 30, 2001 compared to $20.7 million for the year ended September 30, 2000 and $4.4 million for the year ended September 30, 1999. Service revenues increased by 39.1% in fiscal year 2001 and 369.1% in fiscal year 2000. These increases primarily resulted from an increase in the installed base of our products and the renewal of service and support contracts by our current customers.

      Customers who purchase our products can utilize our installation services and an initial customer support contract, typically covering a 12-month period. We generally combine the software license, installation, and customer support elements of our products into a package with a single price. We allocate a portion of the sales price to each element of the bundled package based on their respective fair values when the individual elements are sold separately. Customers may also purchase consulting services and renew their initial customer support contract.

      Cost of net revenues. Cost of net revenues consists primarily of outsourced hardware components and manufacturing costs, fees for third-party software products integrated into our products, service and support personnel and an allocation of our facilities and depreciation expenses.

      Cost of product revenues. Cost of product revenues increased 34.8% to $33.2 million for the year ended September 30, 2001 from $24.7 million for the year ended September 30, 2000. The cost of product revenues for fiscal 2000 represents a 341.8% increase over cost of product revenues of $5.6 million for the year ended September 30, 1999. Cost of product revenues increased as a percent of net product revenue to 42.3% for fiscal year 2001 from 28.0% for fiscal year 2000 and 23.8% for fiscal year 1999. The increase in fiscal 2001 was the result of costs associated with platform changes and an increase in personnel costs. The increase in fiscal 2000 was the result of higher production costs associated with hardware configuration enhancements and also changes related to obsolete inventory and purchase commitments. The cost of raw materials may fluctuate in the future, which could have a negative impact on our gross margin.

      Cost of service revenues. Cost of service revenues increased to $12.3 million for fiscal 2001 from $7.9 for fiscal 2000 and $1.6 million for fiscal 1999. Cost of service revenues increased as a percent of net service revenues to 42.7% for fiscal year 2001 from 38.3% for fiscal year 2000 and 36.7% for fiscal year 1999. The increase in cost of service revenue in fiscal 2001 and 2000, compared to the prior years, is due to an increase in customer base and an increase in personnel and the related costs.

      Provision for excess inventory. Due to changes in current market conditions and a revision of our sales forecast, a review was made of our inventory needs and an assessment of our future purchase commitments during fiscal 2001. As a result, we determined two provisions for excess inventory and future purchase commitments would be recorded. The first provision for excess inventory was charged to cost of revenues in the amount of $3.9 million, which consisted of a $3.1 million inventory valuation allowance and approximately $800,000 of future purchase commitments. As of September 30, 2001, $1.5 million of this reserve had been utilized. The second provision for excess inventory was in the amount of $1.0 million. This charge is associated with charge is associated with the changes in the configuration of our EDGE-FX Cache product, which will increase the functionality of the product. These costs are associated with updating both existing inventory and product previously sold to customers, as well as costs to fulfill existing purchase commitments and have been included in cost of revenues for the for the fiscal year ended September 30, 2001. As of September 30, 2001, $232,000 of this reserve had been utilized.

      Sales and marketing. Sales and marketing expenses consist primarily of salaries, commissions and related benefits of our sales and marketing staff, costs of our marketing programs, including public relations, advertising and trade shows, and an allocation of our facilities and depreciation expenses. Sales and marketing expenses increased by 37.6% to $50.8 million in fiscal 2001 from $36.9 million in fiscal year 2000. In fiscal 2000, sales and marketing expenses increased by 173% from $13.5 million in fiscal 1999. The increase in fiscal 2001, compared to the prior year, was due to an increase in headcount and the related costs, an increase in advertising and promotional activities including activities related to new product launches. The increase in fiscal 2000 was primarily due to a significant increase in headcount from the prior year. We expect to continue increasing sales and marketing expenses in order to grow net revenues and expand our brand awareness.

      Research and development. Research and development expenses consist primarily of salaries and related benefits for our product development personnel and an allocation of our facilities and depreciation expenses. Research and development expenses increased by 20.4% to $17.4 million in fiscal 2001 from $14.5 million, and in fiscal 2000 by 156% from $5.6 million in fiscal 1999. The increase in fiscal year 2001 relates primarily to personnel related costs and an increase in facilities cost related to the new Spokane office. The increase in fiscal 2000, compared to the prior period, is also due to a significant increase in headcount. Our future success is dependent, in large part on the continued enhancement of our current products and our ability to develop new, technologically advanced products that meet the sophisticated needs of our customers. We expect research and development expenses to remain at a consistent level with fiscal 2001.

      General and administrative. General and administrative expenses consist primarily of salaries, benefits and related costs of our executive, finance, human resource and legal personnel, third-party professional service fees, and an allocation of our facilities and depreciation expenses. General and administrative expenses increased by 93.0% in fiscal 2001 to $18.8 million from $9.7 in fiscal year 2000. These expenses increased in fiscal year 2000 by 151.4% from $3.9 million for fiscal year 1999. The increases in fiscal 2001 were due to an increase in bad debt expense due to the relationship with Exodus Communications and an increase in headcount and other payroll related costs. The fiscal 2000 increase was primarily due to increases in the general and administrative headcount.

      Restructuring charge. During the first fiscal quarter of 2001, we recorded a restructuring charge of $1.1 million in connection with management decision to bring operating expenses in line with the business

revenue growth model. As a result of change in the business revenue growth model, we terminated 96 employees throughout all divisions of the company. As of September 30, 2001, substantially all of the restructuring charge accrued for during the first fiscal quarter of 2001, had been paid.

      Unearned compensation. We have recorded a total of $8.3 million of stock compensation costs since our inception through September 30, 2001. These charges represent the difference between the exercise price and the deemed fair value of certain stock options granted to our employees and outside directors. These options generally vest ratably over a four-year period. We are amortizing these costs using an accelerated method as prescribed by FASB interpretation No. 28 (“FIN No. 28”) and have recorded stock compensation charges of $2.6 million, $2.1 million and $2.5 million for the years ended September 30, 2001, 2000 and 1999, respectively.

      We expect to recognize amortization expense related to unearned compensation of approximately $443,000 and $83,000 during the years ended September 30, 2002 and 2003, respectively. We cannot guarantee, however, that we will not accrue additional stock compensation costs in the future or that our current estimate of these costs will prove accurate.

      Other income, net. Other income consists primarily of earnings on our cash and cash equivalent balances and short-term investments. Other income decreased 30.0% to $2.0 million in fiscal year 2001 from $2.9 million in fiscal year 2000. Other income increased by 444.0% in fiscal 2000 from $0.6 million in fiscal year 1999. These fluctuations primarily relate to interest income of $2.6 million for fiscal year 2001, $3.2 million for the fiscal year 2000 and $0.5 million for the fiscal year 1999.

      Income taxes. The income tax provision increased to $4.1 million in fiscal 2001 from $2.1 million in fiscal 2000 and zero in fiscal 1999. The increase in the provision for income taxes was caused by our decision to provide for a full valuation allowance against its deferred tax assets in fiscal year 2001. FASB Statement 109 provides for the recognition of deferred tax assets if it is more likely than not that those deferred tax assets will be realized. Based on the available evidence at the time, the valuation allowance was partially reversed in fiscal year 2000 for the assets we considered realizable. In fiscal year 2001, the changes in the current economic environment caused us reevaluate the need to provide for a full valuation allowance. Based on the weight of all the available positive and negative evidence, we determined that a full valuation allowance should be provided to completely offset the net deferred tax assets.

Liquidity and Capital Resources (in thousands)

                         
Year Ended September 30

2001 2000 1999



Working Capital
  $ 74,407     $ 66,136     $ 25,873  
Cash and cash investments
    69,300       53,017       24,797

Cash provided by financing activities
    36,343       35,084       26,225  

      From our inception through May 1999, we financed our operations and capital expenditures primarily through the sale of approximately $12.4 million in equity securities. In June 1999, we completed an initial public offering of 2,860,000 shares of common stock and raised approximately $25.5 million, net of offering costs. In October 1999, we completed a secondary public offering of 500,000 shares of common stock and raised approximately $31.4 million, net of offering costs.

      On June 26, 2001, we entered into a Common Stock and Warrant Purchase Agreement with Nokia Finance International B.V. (“NFI”). Under this agreement, we issued and sold to NFI (i) 2,466,421 shares of common stock and (ii) warrants (the “Warrants”) to purchase additional shares of common stock. We received total proceeds of $34.9 million, net of $1.8 million in estimated issuance costs from the sale of these shares and the Warrants. The Warrants allow NFI to purchase additional shares of common stock to increase its ownership percentage in the company (up to a maximum of one share less than 20%) during three ten business day periods beginning on December 31, 2001, June 30, 2002 and December 31, 2002, at an exercise price equal to the average 10-day closing price before the start of each period.

      We recorded the issuance of the common stock and Warrants by allocating the net proceeds to the Common Stock and the Warrants, based upon their relative fair values at the date of issuance. The fair value allocated to the Warrants was $1.7 million based on an independent valuation. Based upon the relative fair value at the date of issuance, the amount of net proceeds allocated to the Warrants and included as a component of common stock was $1.6 million. The amount allocated to the common stock was $33.3 million.

      Cash used in operating activities during fiscal 2001 was $11.7 million, compared to cash provided by operating activities of $9.8 million in fiscal 2000 and cash used in operating activities of $2.0 million in fiscal 1999. Cash used in operating activities in fiscal 2001 resulted primarily from operating losses, partially offset by a decrease in net accounts receivable. Cash used for operating expenses in fiscal 1999 resulted from increases in accounts receivable due to increased sales and other current assets, which were partially offset by increases in accounts payable, accrued liabilities and deferred revenues.

      Cash used in investing activities was $8.1 million for the year ended September 30, 2001, $16.3 million for the year ended September 30, 2000 and $5.6 million for the year ended September 30, 1999. The $8.1 million used in fiscal 2001 includes $9.2 million used to purchase property and equipment, partially offset by a construction refund. The cash used for investing activities in fiscal 2000 was the result of $13.3 million used to purchase property and equipment and $3.0 million used to invest in restricted cash in order to obtain an irrevocable standby letter of credit to secure our commitment to lease office space. In fiscal 1999, the $5.6 million cash used in investing activities was the result of $2.6 million used to purchase property and equipment and $3.0 million used to invest in restricted cash related to the lease.

      As of September 30, 2001, our principal commitments consisted of obligations outstanding under operating leases. In April 2000, we entered into a lease agreement on two buildings for a new corporate headquarters. The lease commenced in July 2000 on the first building; and the lease on the second building commenced in October 2000. The lease for both buildings expires in 2012 with an option for renewal. We established a restricted escrow account in connection with this lease agreement. Under the term of the lease, a $6.0 million irrevocable standby letter of credit is required through November 2012, unless the lease is terminated before then. This amount has been included on our balance sheet as of September 30, 2001 as a component of restricted cash. Although we have no other material commitments, we anticipate an increase in our capital expenditures and lease commitments consistent with our anticipated growth in our operations, infrastructure and personnel. In the future we may also require a larger inventory of products in order to provide better availability to customers and achieve purchasing efficiencies. Any such increase can be expected to reduce cash, cash equivalents and short-term investments. We expect that our existing cash balances and cash from operations will be sufficient to meet our anticipated working capital and capital expenditures for the foreseeable future.

Recent Accounting Pronouncements

      In July of 2001 the Financial Accounting Standards Board (“FASB”) issued Statement of Financial Accounting Standard (“SFAS”) No. 141 “Business Combinations” which is effective for all business combinations initiated after July 1, 2001. SFAS No. 141, supersedes APB Opinion No. 16, Business Combinations, and FASB Statement No. 38, Accounting for Pre-acquisition Contingencies of Purchased Enterprises and requires that all business combinations be accounted for using the purchase method of accounting. Further, SFAS No. 141 requires certain intangibles to be recognized as assets apart from goodwill if they meet certain criteria and also requires expanded disclosures regarding the primary reasons for consummation of the combination and the allocation of the purchase price paid to the assets acquired and liabilities assumed by major balance sheet caption. We do not believe the standard will have a significant impact on our financial position.

      In July of 2001, the FASB issued SFAS No. 142 “Goodwill and Other Intangible Assets” which is effective for fiscal years beginning after December 15, 2001. SFAS No. 142 supercedes APB Opinion No. 17, Intangible Assets, and addresses financial accounting and reporting for intangible assets acquired individually or with a group of other assets and the accounting and reporting for goodwill and other intangible assets subsequent to their acquisition. Under the model set forth in SFAS No. 142, goodwill is no longer amortized to earnings, but instead be subject to periodic testing for impairment. We do not believe the standard will have a significant impact on our financial position.

      In July 2001, the FASB issued SFAS No. 143, “Accounting for Asset Retirement Obligations.” FASB 143 addresses financial accounting and reporting for obligations associated with the retirement of tangible long-lived assets and the associated asset retirement costs. It applies to legal obligations associated with the retirement of long-lived assets that result from the acquisition, construction, development, and (or) the normal operation of a long-lived asset, except for certain obligations of lessees. The provisions of FAS 143 will be effective for fiscal years beginning after June 15, 2002, however early application is permitted. We do not believe FAS 143 will have a significant impact on our financial statements.

      In August 2001, the FASB issued SFAS No. 144 “Accounting for the Impairment or Disposal of Long-Lived Assets.” This Statement addresses financial accounting and reporting for the impairment or disposal of

24


Table of Contents

long-lived assets. This Statement 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 of APB Opinion No. 30, Reporting the Results of Operations — Reporting the Effects of Disposal of a Segment of a Business, and Extraordinary, Unusual and Infrequently Occurring Events and Transactions, for the disposal of a segment of a business. The provisions of FAS 144 will be effective for fiscal years beginning after December 15, 2001. We are currently evaluating the implications of adoption of FAS 144 and anticipates adopting its provisions in fiscal year 2002.

Risk Factors

      In addition to the other information in this report, the following risk factors should be carefully considered in evaluating our company and its business.

     Our quarterly operating results are volatile and may cause our stock price to fluctuate.

      Our quarterly operating results have varied significantly in the past and will vary significantly in the future, which makes it difficult for us to predict our future operating results. In particular, we anticipate that the size of customer orders may increase as we continue to focus on larger business accounts. A delay in the recognition of revenue, even from just one account, may have a significant negative impact on our results of operations for a given period. In the past, a significant portion of our sales have been realized near the end of a quarter. Accordingly, a delay in an anticipated sale past the end of a particular quarter may negatively impact our results of operations for that quarter. Furthermore, we base our decisions regarding our operating expenses on anticipated revenue trends and our expense levels are relatively fixed. Consequently, if revenue levels fall below our expectations, our net income will decrease because only a small portion of our expenses vary with our revenues. See Item 7 of Part II — “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

      We believe that period-to-period comparisons of our results of operations are not meaningful and should not be relied upon as indicators of future performance. Our operating results may be below the expectations of securities analysts and investors in some future quarter or quarters. Our failure to meet these expectations will likely seriously harm the market price of our common stock.

     Our business may be harmed by economic and market conditions.

      Our business is subject to the effects of general economic conditions in the United States and globally and market conditions in the Internet and technology sectors in particular. Unfavorable economic conditions and reduced capital spending has contributed to a decline in our product sales during the fourth quarter of fiscal 2001. A continued downturn in the economic conditions or economic uncertainty could adversely impact potential customers’ ability and willingness to purchase our products, which would cause a further decline in our sales and operating results.

     Our success depends on sales of our BIG-IP®.

      We currently derive approximately 64% of our net revenues from sales of our BIG-IP product line. In addition, we expect to derive a significant portion of our net revenues from sales of BIG-IP in the future. Implementation of our strategy depends upon BIG-IP being able to solve critical network availability and performance problems of our customers. If BIG-IP is unable to solve these problems for our customers, our business and results of operations will be seriously harmed.

     Our success depends on our timely development of new products and features.

      We expect the Internet traffic and content management market to be characterized by rapid technological change, frequent new product introductions, changes in customer requirements and evolving industry standards. Our continued success depends on our ability to identify and develop new products and new features for our existing products to meet the demands of these changes, and for those products and features to be accepted by our existing and target customers. If we are unable to identify, develop and deploy new

25


Table of Contents

products and new product features on a timely basis, or if those products do not gain market acceptance, our business and results of operations may be seriously harmed. See Item 1 of Part I — “Business — Product Development.”
 
We may not be able to compete effectively in the emerging Internet traffic and content management market.

      Our markets are new, rapidly evolving and highly competitive, and we expect competition to persist and intensify in the future. Our principal competitors in the Internet traffic and content management market include Cisco Systems, CacheFlow, Foundry Networks, Inktomi, Network Appliances, Extreme Networks, Nortel Networks and RadWare. We expect to continue to face additional competition as new participants enter the Internet traffic and content management market. In addition, larger companies with significant resources, brand recognition and sales channels may form alliances with or acquire competing Internet traffic and content management solutions and emerge as significant competitors. Potential competitors may bundle their products or incorporate an Internet traffic and content management component into existing products in a manner that discourages users from purchasing our products. Potential customers may also choose to purchase additional or larger servers instead of our products. See Item 1 of Part I — “Business — Competition.”

 
The average selling price of our products may decrease and our costs may increase, which may negatively impact gross profits.

      We anticipate that the average selling prices of our products will decrease in the future in response to competitive pricing pressures, increased sales discounts, new product introductions by us or our competitors or other factors. Therefore, in order to maintain our gross profits, we must develop and introduce new products and product enhancements on a timely basis and continually reduce our product costs. Our failure to do so will cause our net revenue and gross profits to decline, which will seriously harm our business and results of operations. In addition, we may experience substantial period-to-period fluctuations in future operating results due to the erosion of our average selling prices.

 
It is difficult to predict our future operating results because we have an unpredictable sales cycle.

      Our products have a lengthy sales cycle which is difficult to predict. Historically, our sales cycle has ranged from approximately two to three months. Sales of BIG-IP, 3-DNS, GLOBAL-SITE, SEE-IT, and EDGE-FX require us to educate potential customers in their use and benefits. The sale of our products is subject to delays from the lengthy internal budgeting, approval and competitive evaluation processes that large corporations and governmental entities may require. For example, customers frequently begin by evaluating our products on a limited basis and devote time and resources to testing our products before they decide whether or not to purchase. Customers may also defer orders as a result of anticipated releases of new products or enhancements by us or our competitors. As a result, our products have an unpredictable sales cycle that contributes to the uncertainty of our future operating results.

 
We may not be able to sustain or develop new distribution relationships.

      Our sales strategy requires that we establish multiple and maintain distribution channels in the United States and internationally through leading industry resellers, original equipment manufacturers, systems integrators, Internet service providers and other channel partners. We have a limited number of agreements with companies in these channels, and we may not be able to increase our number of distribution relationships or maintain our existing relationships. During fiscal 2001 no single reseller or customer exceeded 10% of net revenue or our accounts receivable balance. If we are unable to establish and maintain our indirect sales channels, our business and results of operations will be seriously harmed.

Our expansion into international markets may not succeed.

      We intend to continue expanding into international markets. We have limited experience in marketing, selling and supporting our products internationally. International sales represented 33% of our net revenues for the year ended September 30, 2001, 19% of our net revenues for the year ended September 30, 2000 and 7.7% of our net revenues for the year ended September 30, 1999. We have engaged sales personnel in Australia, Europe, and Asia Pacific. Our continued growth will require further expansion of our international operations in selected countries in the European and Asia Pacific markets. If we are unable to expand our international operations successfully and in a timely manner, our business and results of operations may be seriously harmed. Such expansion may be more difficult or take longer than we anticipate, and we may not be able to successfully market, sell, deliver and support our products internationally.

 
Our operating results are exposed to risks associated with international commerce.

      As our international sales increase, our operating results become more exposed to international operating risks. These risks include risks related to foreign currency exchange rates, managing foreign sales offices, regulatory, political, or economic conditions in specific countries, changes in laws and tariffs, inadequate protection of intellectual property rights in foreign countries, foreign regulatory requirements, and natural disasters. All of these factors could have a material adverse effect on our business.

 
Our success depends on our key personnel and our ability to attract, train and retain qualified marketing and sales, professional services and customer support personnel.

      Our success depends to a significant degree upon the continued contributions of our key management, product development, sales, marketing and finance personnel, many of whom will be difficult to replace. The complexity of our Internet traffic and content management products and their integration into existing networks and ongoing support, as well as the sophistication of our sales and marketing effort, requires us to retain highly-trained professional services, customer support and sales personnel. In spite of the economic downturn, competition for qualified professional services, customer support and sales personnel in our industry is intense because of the limited number of people available with the necessary technical skills and understanding of our products. Our ability to retain and hire these personnel may be adversely affected by volatility or reductions in our stock price, since these employees are generally granted stock options. The loss of services of any of our key personnel, the inability to retain and attract qualified personnel in the future or delays in hiring qualified personnel, may seriously harm our business and results of operations.

 
Our business may be harmed if our contract manufacturers are not able to provide us with adequate supplies of our products.

      We rely on third party contract manufacturers to assemble our products. We outsource the manufacturing of our pre-configured, industry-standard hardware platforms to three contract manufacturers who assemble these hardware platforms to our specifications. We have experienced minor delays in shipments from these contract manufacturers in the past which have not had a material impact on our results of operations. We may experience delays in the future or other problems, such as inferior quality and insufficient quantity of product, any of which may seriously harm our business and results of operations. The inability of our contract manufacturers to provide us with adequate supplies of our products or the loss of our contract manufacturers may cause a delay in our ability to fulfill orders while we obtain a replacement manufacturer and may seriously harm our business and results of operations.

      If the demand for our products grows, we will need to increase our material purchases, contract manufacturing capacity and internal test and quality functions. Any disruptions in product flow may limit our revenue, may seriously harm our competitive position and may result in additional costs or cancellation of orders by our customers. See Item 1 of Part I — “Business — Manufacturing.”

27


Table of Contents

 
Our business could suffer if there are any interruptions or delays in the supply of hardware components from our third-party sources.

      We currently purchase several hardware components used in the assembly of our products from limited sources. Lead times for these components vary significantly. Any interruption or delay in the supply of any of these hardware components, or the inability to procure a similar component from alternate sources at acceptable prices within a reasonable time, will seriously harm our business and results of operations. See Item 1 of Part I — “Business — Manufacturing.”

 
Undetected software errors may seriously harm our business and results of operations.

      Software products frequently contain undetected errors when first introduced or as new versions are released. We have experienced these errors in the past in connection with new products and product upgrades. We expect that these errors will be found from time to time in new or enhanced products after commencement of commercial shipments. These problems 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. We may also be subject to liability claims for damages related to product errors. While we carry insurance policies covering this type of liability, these policies may not provide sufficient protection should a claim be asserted. A material product liability claim may seriously harm our business and results of operations.

      Our products must successfully operate with products from other vendors. As a result, when problems occur in a network, it may be difficult to identify the source of the problem. The occurrence of software errors, whether caused by our products or another vendor’s products, may result in the delay or loss of market acceptance of our products. The occurrence of any of these problems may seriously harm our business and results of operations.

 
We may not adequately protect our intellectual property and our products may infringe on the intellectual property rights of third parties.

      We rely on a combination of copyright, trademark and trade secret laws and restrictions on disclosure of confidential and proprietary information to protect our intellectual property rights. Despite our efforts to protect our proprietary rights, unauthorized parties may attempt to copy or otherwise obtain and use our products or technology. Monitoring unauthorized use of our products is difficult, and we cannot be certain that the steps we have taken will prevent misappropriation of our technology, particularly in foreign countries where the laws may not protect our proprietary rights as fully as in the United States. In addition, we have not entered into non-competition agreements with several of our former employees.

      From time to time, third parties may assert exclusive patent, copyright, trademark and other intellectual property rights claims or initiate litigation against us or our contract manufacturers, suppliers or customers with respect to existing or future products. Our license agreements typically require us to indemnify our customers for infringement actions related to our technology, which could cause us to become involved in infringement claims against our customers. We may in the future initiate claims or litigation against third parties for infringement of our proprietary rights to determine the scope and validity of our proprietary rights or those of our competitors. Any of these claims, with or without merit, may be time-consuming, result in costly litigation and diversion of technical and management personnel or require us to cease using infringing technology, develop non-infringing technology or enter into royalty or licensing agreements. Such royalty or licensing agreements, if required, may not be available on acceptable terms, if at all. In the event of a successful claim of infringement and our failure or inability to develop non-infringing technology or license the infringed or similar technology on a timely basis, our business and results of operations may be seriously harmed.

 
Our stock price may be volatile.

      Our stock price has historically experienced substantial volatility. In addition, the stock market and technology stocks in particular, have experienced extreme price and volume fluctuations that often have been

28


Table of Contents

unrelated to the performance of these companies. In the future, the price of our stock may be affected by a number of factors, including variations between our operating results and analysts’ expectations, announcements by us or our competitors, or general market conditions.

Item 7A.     Quantitative and Qualitative Disclosure About Market Risk.

      Interest Rate Risk. We do not hold derivative financial instruments or equity securities in our investment portfolio. The Board of Directors authorized one transaction to purchase and sell publicly traded company options. Our cash equivalents consist of high-quality securities, as specified in our investment policy guidelines. The policy limits the amount of credit exposure to any one issue or issuer to a maximum of 20% of the total portfolio with the exception of treasury securities, commercial paper and money market funds, which are exempt from size limitation. The policy limits all short-term investments to mature in two years or less, with the average maturity being one year or less. These securities are subject to interest rate risk and will decrease in value if interest rates increase.

      Foreign Currency Risk. Currently the majority of our sales and expenses are denominated in U.S. dollars and as a result, we have not experienced significant foreign exchange gains and losses to date. While we have conducted some transactions in foreign currencies during the fiscal year ended September 30, 2001 and expect to continue to do so, we do not anticipate that foreign exchange gains or losses will be significant at our current level of operations. However, as we continue to expand our operations internationally, they may become significant in the future. We have not engaged in foreign currency hedging to date, however we may do so in the future.

1.     Description of the Company:

      F5 Networks, Inc. (the “Company”) was incorporated on February 26, 1996 in the State of Washington and is a leading provider of integrated Internet traffic and content management solutions designed to improve the availability and performance of mission-critical Internet-based servers and applications. The Company’s proprietary software-based solutions monitor and manage local and geographically dispersed servers and intelligently direct traffic to the server best able to handle a user’s request. The Company purchases material component parts and certain licensed software from suppliers and generally contracts with third parties for the assembly of products. The Company operates in one segment providing integrated internet traffic and content management solutions.

2.     Summary of Significant Accounting Policies:

Principles of Consolidation

      The consolidated financial statements and accompanying notes are prepared in accordance with accounting principles generally accepted in the United Sates of America. The consolidated financial statements include the accounts of the Company and all majority owned subsidiaries. Significant intercompany transactions have been eliminated in consolidation.

Reclassifications

      Certain reclassifications have been made to prior year balances to conform to the current year presentation. These reclassifications had no impact on previously reported net loss, shareholders’ equity or cash flows.

Use of Estimates

      The preparation of financial statements is in conformity with accounting principles generally accepted in the United States of America and requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

      Estimates that are particularly susceptible to changes in the near term are the adequacy of allowances for sales returns and bad debt, inventory obsolescence, warranty costs and deferred taxes.

Cash Equivalents and Short-term Investments

      Cash equivalents are highly liquid investments, consisting of investments in money market funds and short-term investments which are readily convertible to cash without penalty and subject to insignificant risk of changes in value. The Company’s cash equivalents and short term investments balance consists of the following (in thousands):

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

Concentration of Credit Risk

      The Company places its temporary cash investments with five major financial institutions.

      The Company’s customers are from diverse industries and geographic locations. Net revenues from international customers are primarily denominated in U.S. Dollars and were approximately $35.0 million, $20.6 million and $2.2 million for the years ended September 30, 2001, 2000 and 1999, respectively. During fiscal 2001 no single reseller or customer exceeded 10% of the Company’s net revenue or accounts receivable balance. During fiscal 2000 and 1999, one of the Company’s resellers, Exodus Communications, accounted for 14% and 22% of net revenue and 8% and 16% of the Company’s accounts receivable balance, respectively. In association with Exodus filing Chapter 11 bankruptcy, the Company recorded a non-recurring adjustment to its bad-debt expense of $1.75 million and $226,000 in cost of goods sold related to the leased inventory during fiscal 2001. The Company does not require collateral to support credit sales. Allowances are maintained for potential credit losses and sales returns.

Inventories

      Inventories consist of hardware and the related component parts and are recorded at the lower of cost or market (as determined by the first-in, first-out method).

Restricted Cash

      Restricted cash represents a restricted escrow account established in connection with a lease agreement for the company’s corporate headquarters. Under the term of the lease, a $6.0 million standby letter of credit is required through November 2012, unless the lease is terminated before then.

Property and Equipment

      Property and equipment is stated at cost. Depreciation of property and equipment and amortization of capital leases are provided on the straight-line method over the estimated useful lives of the assets of 2 to 5 years. Leasehold improvements are amortized over the lesser of the term of the lease or the estimated useful life of the improvements.

      The cost of normal maintenance and repairs is charged to expense as incurred and expenditures for major improvements are capitalized at cost. Gains or losses on the disposition of assets in the normal course of business are reflected in the results of operations at the time of disposal.

Software Development Costs

      Software development costs incurred in conjunction with product development are charged to research and development expense until technological feasibility is established. Thereafter, until the product is released for sale, software development costs are capitalized and reported at the lower of unamortized cost or net realizable value of each product. The establishment of technological feasibility and the on-going assessment of recoverability of costs require considerable judgment by the Company with respect to certain internal and external factors, including, but not limited to, anticipated future gross product revenues, estimated economic life and changes in hardware and software technology. The Company amortizes capitalized software costs using the straight-line method over the estimated economic life of the product, generally three years. In fiscal 2001, the Company capitalized $327,000 in software development costs, generally representing labor costs, and recorded no related amortization.

Valuation of Long-Lived Assets

      The Company periodically evaluates the carrying value of long-lived assets to be held and used, including, but not limited to, property and equipment, other assets, and deferred income taxes, when events and circumstances warrant such a review. The carrying value of a long-lived asset is considered impaired when the anticipated undiscounted cash flow from the asset is separately identifiable and is less than its carrying value. In that event, a loss is recognized based on the amount by which the carrying value exceeds the fair value of the long-lived asset. Fair value is determined primarily using the anticipated cash flows discounted at a rate commensurate with the risk involved. Losses on long-lived assets to be disposed of are determined in a similar manner, except that fair values are reduced for the cost to dispose.

Revenue Recognition

      The Company recognizes revenue under Statement of Financial Accounting Standards (SFAS) No. 48, “Revenue Recognition When Right of Return Exists,” SEC Staff Accounting Bulleting (SAB) No. 101, “Revenue Recognition in Financial Statements,” Statement of Position (“SOP”) No. 97-2, “Software Revenue Recognition,” and SOP No. 98-9 “Modification of SOP No. 97-2, Software Revenue Recognition, with Respect to Certain Transactions.”

      The Company sells products through resellers, original equipment manufacturers and other channel partners, as well as to end users, under similar terms. Typically this combines software license, installation and customer support elements into a package with a single “bundled” price and allocates a portion of the sales price to each element of the bundled package based on their respective fair values when the individual elements are sold separately. Revenues from the license of software, net of an allowance for estimated returns, are recognized when the product has been shipped and the customer is obligated to pay for the product. Installation revenue is recognized when the product has been installed at the customer’s site. Revenues for customer support are recognized on a straight-line basis over the service contract term. Estimated sales returns are based on historical experience by product and are recorded at the time revenues are recognized.

      The following presents revenues by shipment destination for the years ended 2001, 2000 and 1999 (in thousands):

    $ 107,367     $ 108,645     $ 27,825  
     
     
     
 

Warranty Expense

      The Company generally offers warranties between 90 days and one year depending on whether it relates to hardware or software. Estimated future warranty obligations related to products are provided by charges to operations in the period in which the related revenue is recognized. These estimates are based on historical warranty experience and other relevant information of which the Company is aware. During the years ended September 30, 2001, 2000 and 1999 warranty expense was $0.4 million, $2.3 million and $0.3 million, respectively.

Advertising

      Advertising costs are expensed as incurred. Advertising expense was approximately $1.5 million, $1.6 million and $1.0 million for the years ended September 30, 2001, 2000 and 1999, respectively.

Income Taxes

      The Company accounts for income taxes under the liability method of accounting. Under the liability method, deferred taxes are determined based on the differences between the financial statement and tax bases of assets and liabilities at enacted tax rates in effect in the year in which the differences are expected to reverse. Valuation allowances are established, when necessary, to reduce deferred tax assets to estimated amounts expected to be realized.

Foreign Currency Translation

      The financial statements of F5 Networks, Ltd., F5 Networks, Singapore Pte. Ltd. and F5 Networks, Japan K.K. have been translated into U.S. dollars in accordance with Statement of Financial Accounting Standards No. 52 “Foreign Currency Translation.” Under the provisions of this Statement, all assets and liabilities in the balance sheet of the subsidiaries are translated at year-end exchange rates, and translation gains and losses are reported as a component of comprehensive income (loss) and are accumulated in a separate component of shareholders’ equity. Foreign currency transaction gains and losses are a result of the effect of exchange rate changes on transactions denominated in currencies other than the functional currency, including US dollars. Gains and losses on those foreign currency transactions are included in determining net income or loss for the period of exchange. Transaction losses for the fiscal years ended September 30, 2001, 2000 and 1999 of $139,000, $84,000, and $0, respectively, were charged to operations.

Comprehensive Income (Loss)

      The Financial Accounting Standards Board issued Statement of Financial Accounting Standards No. 130, “Reporting Comprehensive Income,” in June 1997. This statement establishes standards for reporting and displaying comprehensive income in the financial statements and was adopted by the Company during the quarter ended September 30, 1999. In addition to net income (loss), comprehensive income (loss) includes charges or credits to equity that are not the result of transactions with shareholders. For the Company, this includes foreign currency translation and unrealized gains and losses on investments. The Company has included components of comprehensive income within the Consolidated Statements of Shareholders’ Equity.

Stock-Based Compensation

      The Company accounts for stock-based employee compensation arrangements in accordance with the provisions of Accounting Principles Board Opinion No. 25 (“APB No. 25”), “Accounting for Stock Issued to Employees” and FASB interpretation No. 44 (“FIN No. 44”) accounting for certain transactions involving stock compensation, and complies with the disclosure provisions of Statement of Financial Accounting Standards No. 123 (“SFAS No. 123”), “Accounting for Stock-Based Compensation.” Under APB No. 25, compensation expense is based on the difference, if any, on the date of the grant, between the deemed fair value of the Company’s stock and the exercise price of the option. The unearned compensation is being amortized in accordance with Financial Accounting Standards Board Interpretation No. 28 on an accelerated basis over the vesting period of the individual options. The Company accounts for equity instruments issued to nonemployees in accordance with the provisions of SFAS No. 123.

Fair Value of Financial Instruments

      For certain financial instruments, including cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities, recorded amounts approximate market value, due to the short maturities of these instruments.

Earnings per Share

      Basic net income (loss) per share is computed by dividing net income (loss) by the weighted average number of common shares outstanding during the period. Diluted net income (loss) per share is computed by dividing net income (loss) by the weighted average number of common and dilutive common stock equivalent shares outstanding during the period. For periods in which the Company incurred a net loss, dilutive common stock equivalent shares are excluded from the calculation as their impact would have been antidilutive. The antidilutive securities not included in diluted net loss per share calculation totaled 1,533,386 shares.

      The following table sets forth the computation of basic and diluted net income (loss) per share for the years ended September 30, 2001, 2000 and 1999 (in thousands, except per share data).

Derivatives

      In the first quarter of fiscal 2001, the Company adopted Statement of Financial Accounting Standards No. 133, “Accounting for Derivative Instruments and Hedging Activities (“SFAS 133”) which establishes accounting and reporting standards for derivative instruments and for hedging activities. SFAS 133 requires that an entity recognize derivatives as either assets or liabilities on the balance sheet and measure those instruments at fair value. The accounting for changes in the fair value of a derivative depends on the intended use of the derivative and the resulting designation.

      The Company designates the derivatives based upon criteria established by SFAS 133. For a derivative designated as a fair value hedge, the gain or loss is recognized in earnings in the period of change together with the offsetting loss or gain on the hedged item attributed to the risk being hedged. For a derivative designated as a cash flow hedge, the effective portion of the derivative’s gain or loss is initially reported as a component of accumulated other comprehensive income (loss) and subsequently reclassified into earnings when the hedged exposure affects earnings. The ineffective portion of the gain or loss is reported in earnings immediately. The impact of derivatives on the Company’s financial position in fiscal 2001, has been insignificant.

New Accounting Pronouncements

      In July of 2001 the Financial Accounting Standards Board (“FASB”) issued Statement of Financial Accounting Standard (“SFAS”) No. 141 “Business Combinations” which is effective for all business combinations initiated after July 1, 2001. SFAS No. 141, supersedes APB Opinion No. 16, Business Combinations, and FASB Statement No. 38, Accounting for Preacquisition Contingencies of Purchased Enterprises and requires that all business combinations be accounted for using the purchase method of accounting. Further, SFAS No. 141 requires certain intangibles to be recognized as assets apart from goodwill if they meet certain criteria and also requires expanded disclosures regarding the primary reasons for consummation of the combination and the allocation of the purchase price paid to the assets acquired and liabilities assumed by major balance sheet caption. The Company does not believe the standard will have a significant impact on the financial position of the company.

      In July of 2001, the FASB issued SFAS No. 142 “Goodwill and Other Intangible Assets” which is effective for fiscal years beginning after December 15, 2001. SFAS No. 142 supercedes APB Opinion No. 17, Intangible Assets, and addresses financial accounting and reporting for intangible assets acquired individually or with a group of other assets and the accounting and reporting for goodwill and other intangible assets subsequent to their acquisition. Under the model set forth in SFAS No. 142, goodwill is no longer amortized to earnings, but instead be subject to periodic testing for impairment. The Company does not believe the standard will have a significant impact on the financial position of the company.

      In July 2001, the FASB issued SFAS No. 143, “Accounting for Asset Retirement Obligations.” FASB 143 addresses financial accounting and reporting for obligations associated with the retirement of tangible long-lived assets and the associated asset retirement costs. It applies to legal obligations associated with the retirement of long-lived assets that result from the acquisition, construction, development, and (or) the normal operation of a long-lived asset, except for certain obligations of lessees. The provisions of FAS 143 will be effective for fiscal years beginning after June 15, 2002, however early application is permitted. The Company does not believe the standard will have a significant impact its financial statements.

      In August 2001, the FASB issued SFAS No. 144 “Accounting for the Impairment or Disposal of Long-Lived Assets.” This Statement addresses financial accounting and reporting for the impairment or disposal of long-lived assets. This Statement 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 of APB Opinion No. 30, Reporting the Results of Operations — Reporting the Effects of Disposal of a Segment of a Business, and Extraordinary, Unusual and Infrequently Occurring Events and Transactions, for the disposal of a segment of a business. The provisions of FAS 144 will be effective for fiscal years beginning after December 15, 2001. The Company is currently evaluating the implications of adoption of FAS 144 and anticipates adopting its provisions in fiscal year 2002.

      The Company’s deferred tax assets include net operating loss carry forwards of approximately $27 million. During the first three quarters of fiscal year 2001, the Company maintained a partial valuation allowance consistent with prior year against its deferred tax assets. In the fourth quarter of fiscal year 2001, the Company re-evaluated the need to provide a full valuation allowance. Due to changes in the current economic environment and based on the weight of all the available positive and negative evidence, the Company determined that it was not more likely than not, that the deferred taxes would be recognized and therefore, a full valuation allowance should be provided to completely offset the net deferred tax assets.

during which these awards may be exercised) will accelerate and the options or awards terminated if not exercised before the change in control. As of September 30, 2001 there were 4,028,923 shares outstanding and 819,766 shares available.

Stock options granted under this plan typically vest over a period of four years from the grant date, and expire 10 years from the grant date. The Company has not granted any stock purchase awards or stock bonuses under the 2000 Plan. Upon certain changes in control of the Company, the surviving entity will either assume or substitute all outstanding options or stock awards under the 2000 Plan. If the surviving entity determines not to assume or substitute such options or awards, then with respect to persons whose service with the Company or an affiliate of the Company has not terminated before a change in control, the vesting of 50% of these options or stock awards (and the time during which these awards may be exercised) will accelerate and the options or awards will be terminated if not exercised before the change in control. As of September 30, 2001 there were options to purchase 1,963,414 shares outstanding and 36,371 shares available for awards under the 2000 plan.

      In July 2000, the Company’s Board of Directors adopted two nonqualified stock option plans (the “McAdam Plans”) in connection with hiring John McAdam, the Company’s President and Chief Executive Officer. The first McAdam Plan provides for a grant of 645,000 non-qualified stock options for Mr. McAdam that vest over a period of four years from the grant date. The second McAdam Plan provides for a grant of 50,000 options for Mr. McAdam that vest over a period of two years from the grant date. All options under the McAdam Plans expire 10 years from the grant date, and upon certain changes in control of the Company, the vesting of 100% of these options will accelerate and the options will be terminated if not exercised before the change in control. As of September 30, 2001, 50,000 shares had been issued, there were options to purchase 645,000 shares outstanding and no shares available.

      In October 2000, the Company’s Board of Directors adopted a non-qualified stock option plan in connection with the hiring of Jeff Pancottine, the Company’s Senior Vice President of Marketing and Business Development. This Plan provides for a grant of 200,000 non-qualified stock options for Mr. Pancottine that vest ratably over a period of four years from the grant date. All options under this plan expire 10 years from the grant date. As of September 30, 2001, there were options to purchase 200,000 shares outstanding and no shares available for grant.

      In May 2001, the Company’s Board of Directors adopted a non-qualified stock option plan in connection with the hiring of Steve Coburn, the Company’s Vice President of Finance and Chief Financial Officer. This plan provides for a grant of 200,000 non-qualified stock options for Mr. Coburn that vest ratably over a period of four years. All options under this plan expire 10 years from the grant date. As of September 30, 2001, there were 200,000 stock option shares outstanding and no shares available available for grant.

      The Company applies the provisions prescribed in APB No. 25 and related interpretations in accounting for stock options. In certain instances, the Company has issued stock options with an exercise price less than the deemed fair value of the Company’s common stock at the date of grant. Accordingly, total compensation costs related to these stock options of approximately $0.1 million, $2.0 million and $4.0 million was deferred

during fiscal years 2001, 2000 and 1999, respectively, and is being amortized over the vesting period of the options, generally four years. Amortization of stock compensation costs of approximately $2.6 million, $2.1 million and $2.5 million has been recognized as an expense for the years ended September 30, 2001, 2000 and 1999, respectively.

1999 Employee Stock Purchase Plan

      In May 1999, the board of directors approved the adoption of the 1999 Employee Stock Purchase Plan (the “Purchase Plan”). A total of 1,000,000 shares of common stock has been reserved for issuance under the Purchase Plan. The Purchase Plan permits eligible employees to acquire shares of the Company’s common stock through periodic payroll deductions of up to 15% of base compensation. No employee may purchase more than $25,000 worth of stock, determined at the fair market value of the shares at the time such option is granted, in one calendar year. The Purchase Plan has been implemented in a series of offering periods, each 6 months in duration. The price at which the common stock may be purchased is 85% of the lesser of the fair market value of the Company’s common stock on the first day of the applicable offering period or on the last day of the respective purchase period.

      Pro forma information regarding net income (loss) is required by SFAS No. 123, and has been determined as if the Company had accounted for its stock options under the minimum value method of that statement for all periods prior to the Company becoming a public entity and fair value method of that statement for all periods subsequent to the Company becoming a public entity. The fair value of each option is estimated at the date of grant with the following weighted-average assumptions used for the years ended September 30, 2001, 2000 and 1999:

      For purposes of pro forma disclosures, the estimated fair value of the options is amortized over the options’ vesting period. The Company’s pro forma net income (loss) would have been as follows (in thousands, except per share data):

      Rent expense under non-cancelable operating leases amounted to approximately $4.8 million, $1.9 million and $0.5 million for the years ended September 30, 2001, 2000, and 1999, respectively.

      In April 2000, the Company entered into a lease agreement on two buildings for a new corporate headquarters. The lease commenced in July 2000 on the first building; and the lease on the second building commenced in October 2000. The lease for both buildings expires in 2012 with an option for renewal. The Company established a restricted escrow account in connection with this lease agreement. Under the term of the lease, a $6.0 million irrevocable standby letter of credit is required through November 2012, unless the lease is terminated before then. This amount has been included on the Company’s balance sheet as of September 30, 2000 as a component of restricted cash. The Company has surplus office space of approximately 14,000 square feet which it subleased until 2003 and approximately 110,000 square feet which it subleased until 2012.

      On August 8, 2001 a putative securities class action, captioned Atlas v. F5 Networks, Inc. et al., Civil Action No. 01-CV-7342, was filed against the firms that underwrote F5 Networks’ initial public offering, F5 Networks, and several of its officers and directors in the United States District Court for the Southern District of New York. The complaint alleges violations of Sections 11 and 15 of the Securities Exchange Act of 1933 and Section 10(b) and Rule 10b-5 promulgated thereunder and Section 20(a) of the Securities Exchange Act of 1934 against the Company and its officers and directors, and seeks unspecified damages on behalf of a purported class that purchased F5 Networks’ common stock between June 4, 1999 and December 6, 2000.

      On August 15, 2001 a similar complaint, captioned Lee v. F5 Networks, Inc. et al., Civil Action No. 01-CV-7625, was filed in the United States District Court for the Southern District of New York. The complaint is substantially identical to the Atlas complaint: it names the same defendants, contains the virtually identical claims, and seeks unspecified damages on behalf of a purported class of purchasers of common stock during an identical class period.

      Various plaintiffs have filed similar actions in the United States District Court for the Southern District of New York asserting virtually identical allegations against more than 200 other issuers. These cases have all been assigned to the Hon. Shira A. Scheindlin for coordination and decisions on pretrial motions, discovery, and related matters other than trial. The Company believes that it has meritorious defenses to the lawsuits and will defend itself vigorously in the litigation. An unfavorable resolution of the actions could have a material, adverse effect on the business, results of operations or financial condition of the Company.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

      The company may be subject to additional legal proceedings, claims and litigation arising in the ordinary course of business. Although the outcome of these matters is currently not determinable, the Company does not expect that the resolution of the actions could have a material, adverse effect on the business, results of operations or financial condition of the Company.

10.     Related Party Transactions:

      In March 1999, the Company issued 150,000 shares of common stock to an officer of the Company in exchange for a note receivable. These shares were acquired by exercising stock options that vest over a period of four years. The note bears interest at a rate of 4.83%, is collateralized by the shares, partially guaranteed by the officer and is due in 2003. In fiscal 2000, total payments of $281,000 were received on the loan. Under the pledge agreement, the Company has the obligation to repurchase any remaining unvested shares, and the note becomes due upon the officer’s termination. Further, the shares may not be transferred until they are vested, and the related portion of the loan is repaid. In fiscal 2001, the officer left the company and returned unvested shares totaling approximately 56,000 options to purchase shares of common stock, which were subsequently cancelled. In fiscal 2001, total payments of $188,000 were received on the loan.

11.     Employee Benefit Plans:

      The Company provides a 401(k) savings plan whereby eligible employees may voluntarily contribute a percentage of their compensation. Under the provision of the plan the Company may, at their discretion, match a portion of the employees’ eligible contributions. Contributions to the plan during the years ended September 30, 2001, 2000 and 1999 were approximately $953,000, $833,000 and $612,000, respectively. Contributions made by the company vest over four years.

58 EX-10.20 3 v77937ex10-20.txt EXHIBIT 10.20 EXHIBIT 10.20 F5 NETWORKS, INC. 2000 EMPLOYEE EQUITY INCENTIVE PLAN STOCK OPTION AGREEMENT Pursuant to the Stock Option Grant Notice ("Grant Notice") and this Stock Option Agreement, F5 Networks, Inc. (the "Company") has granted you an option under its 2000 Employee Equity Incentive Plan (the "Plan") to purchase the number of shares of the Company's Common Stock indicated in the Grant Notice at the exercise price indicated in the Grant Notice. Your option is granted in connection with and in furtherance of the Company's compensatory benefit plan for the Employees, Directors and Consultants of the Company and its Affiliates. Defined terms not explicitly defined in this Stock Option Agreement but defined in the Plan shall have the same definitions as in the Plan. The details of your option are as follows: 1. VESTING. Subject to the limitations contained herein, your option will vest as provided in the Grant Notice, provided that vesting will cease upon the termination of your Continuous Service. 2. NUMBER OF SHARES AND EXERCISE PRICE. The number of shares subject to your option and your exercise price per share referenced in the Grant Notice may be adjusted from time to time for Capitalization Adjustments, as provided in the Plan. 3. METHOD OF PAYMENT. Payment of the exercise price is due in full upon exercise of all or any part of your option. You may elect to make payment of the exercise price in cash or by check or in any other manner PERMITTED BY THE GRANT NOTICE, which may include one or more of the following if the Company, in its sole discretion at the time your option is exercised, is then offering such alternatives: (a) Provided that at the time of exercise the Common Stock is publicly traded and quoted regularly in The Wall Street Journal, then pursuant to a program developed under Regulation T as promulgated by the Federal Reserve Board which, prior to the issuance of Common Stock, results in either the receipt of cash (or check) by the Company or the receipt of irrevocable instructions to pay the aggregate exercise price to the Company from the sales proceeds (a "cashless exercise"). (b) Provided that at the time of exercise the Common Stock is publicly traded and quoted regularly in The Wall Street Journal, then by delivery of already-owned shares of Common Stock (valued at their Fair Market Value on the date of exercise) if (i) either you have held the already-owned shares for the period required to avoid a charge to the Company's reported earnings (generally six months) or you did not acquire the already-owned shares, directly or indirectly from the Company, and (ii) you own the already-owned shares free and 1 clear of any liens, claims, encumbrances or security interests. "Delivery" for these purposes, in the sole discretion of the Company at the time your option is exercised, shall include delivery to the Company of your attestation of ownership of such shares of Common Stock in a form approved by the Company. Notwithstanding the foregoing, your option may not be exercised by tender to the Company of Common Stock to the extent such tender would constitute a violation of the provisions of any law, regulation or agreement restricting the redemption of the Company's stock. (c) Provided there has been a change in control described in subsection 11(c) of the Plan and the surviving corporation or acquiring corporation refuses to assume your option or to substitute a similar option for your option, then by authorizing the Company to withhold shares from the shares of the Common Stock otherwise issuable to you as a result of the exercise of your option. Notwithstanding the foregoing, your option may not be exercised by withholding shares of Common Stock to the extent such withholding would constitute a violation of the provisions of any law, regulation or agreement restricting the redemption of the Company's stock. 4. WHOLE SHARES. Your option may only be exercised for whole shares. 5. SECURITIES LAW COMPLIANCE. Notwithstanding anything to the contrary contained herein, your option may not be exercised unless the shares issuable upon exercise of your option are then registered under the Securities Act or, if such shares are not then so registered, the Company has determined that such exercise and issuance would be exempt from the registration requirements of the Securities Act. The exercise of your option must also comply with other applicable laws and regulations governing the option, and the option may not be exercised if the Company determines that the exercise would not be in material compliance with such laws and regulations. 6. TERM. The term of your option commences on the Date of Grant and expires upon the EARLIEST of the following: (a) three (3) months after the termination of your Continuous Service for any reason other than death or Disability, provided that if during any part of such three-month period the option is not exercisable solely because of the condition set forth in paragraph 5, the option shall not expire until the earlier of the Expiration Date or until it shall have been exercisable for an aggregate period of three (3) months after the termination of your Continuous Service; (b) twelve (12) months after the termination of your Continuous Service due to Disability; (c) eighteen (18) months after your death if you die either during your Continuous Service or within three (3) months after your Continuous Service terminates for reason other than Cause; (d) the Expiration Date indicated in the Grant Notice; or 2 (e) the tenth (10th) anniversary of the Date of Grant. If your option is an incentive stock option, note that, to obtain the federal income tax advantages associated with an "incentive stock option," the Code requires that at all times beginning on the date of grant of the option and ending on the day three (3) months before the date of the option's exercise, you must be an employee of the Company or an Affiliate, except in the event of your death or your Disability. The Company has provided for extended exercisability of your option in the event of your death or Disability, but the Company cannot guarantee that your option will necessarily be treated as an "incentive stock option" if you continue to provide services to the Company or an Affiliate as a Consultant or Director after your employment terminates or if you exercise your option more than three (3) months after the date your employment with the Company or an Affiliate terminates. 7. EXERCISE. (a) You may exercise the vested portion of your option during its term by delivering a Notice of Exercise (in a form designated by the Company) together with the exercise price to the Secretary of the Company, or to such other person as the Company may designate, during regular business hours, together with such additional documents as the Company may then require. (b) By exercising your option you agree that, as a condition to any exercise of your option, the Company may require you to enter an arrangement providing for the payment by you to the Company of any tax withholding obligation of the Company arising by reason of (1) the exercise of your option or (2) the disposition of shares acquired upon such exercise. (c) If your option is an incentive stock option, by exercising your option you agree that you will notify the Company in writing within fifteen (15) days after the date of any disposition of any of the shares of the Common Stock issued upon exercise of your option that occurs within two (2) years after the date of your option grant or within one (1) year after such shares of Common Stock are transferred upon exercise of your option. 8. TRANSFERABILITY. Your option is not transferable, except by will or by the laws of descent and distribution, and is exercisable during your life only by you. Notwithstanding the foregoing, by delivering written notice to the Company, in a form satisfactory to the Company, you may designate a third party who, in the event of your death, shall thereafter be entitled to exercise your option. 9. OPTION NOT A SERVICE CONTRACT. Your option is not an employment or service contract, and nothing in your option shall be deemed to create in any way whatsoever any obligation on your part to continue in the employ of the Company or an Affiliate, or of the Company or an Affiliate to continue your employment. In addition, nothing in your option shall obligate the Company or an Affiliate, their respective shareholders, Boards of Directors, Officers or Employees to continue any relationship that you might have as a Director or Consultant for the Company or an Affiliate. 3 10. WITHHOLDING OBLIGATIONS. (a) At the time your option is exercised, in whole or in part, or at any time thereafter as requested by the Company, you hereby authorize withholding from payroll and any other amounts payable to you, and otherwise agree to make adequate provision for (including by means of a "cashless exercise" pursuant to a program developed under Regulation T as promulgated by the Federal Reserve Board to the extent permitted by the Company), any sums required to satisfy the federal, state, local and foreign tax withholding obligations of the Company or an Affiliate, if any, which arise in connection with your option. (b) Your option is not exercisable unless the tax withholding obligations of the Company and/or any Affiliate are satisfied. Accordingly, you may not be able to exercise your option when desired even though your option is vested. 11. NOTICES. Any notices provided for in your option or the Plan shall be given in writing and shall be deemed effectively given upon receipt or, in the case of notices delivered by the Company to you, five (5) days after deposit in the United States mail, postage prepaid, addressed to you at the last address you provided to the Company. 12. GOVERNING PLAN DOCUMENT. Your option is subject to all applicable provisions of the Plan, which are hereby made a part of your option, and is further subject to all interpretations, amendments, rules and regulations which may from time to time be promulgated and adopted pursuant to the Plan. In the event of any conflict between the provisions of your option and those of the Plan, the provisions of the Plan shall control. 4 EX-10.22 4 v77937ex10-22.txt EXHIBIT 10.22 EXHIBIT 10.22 F5 NETWORKS, INC. NONQUALIFIED STOCK OPTION AGREEMENT THIS NONQUALIFIED STOCK OPTION AGREEMENT (the "Agreement") is made and entered into as of May 29, 2001 (the "Grant Date") between F5 Networks, Inc., a Washington corporation (the "Company") and Steve Coburn ("Holder"). THE PARTIES AGREE AS FOLLOWS: 1. GRANT OF OPTION; GRANT DATE. The Company hereby grants to Holder, the right (the "Option") to purchase up to 200,000 shares of the Company's Common Stock (the "Option Shares") at a price per share of $12.72 (the "Exercise Price"), on the terms and conditions set forth in this Agreement. This Option is not intended to qualify as an incentive stock option for purposes of Section 422 of the Code. The number and kind of Option Shares and the Exercise Price may be adjusted in certain circumstances in accordance with the provisions of Section 9 below. 2. DEFINITIONS. For purposes of this Agreement, the following terms shall be defined as set forth below: 2.1 Affiliate. "Affiliate" means any parent corporation or subsidiary corporation of the Company, whether now or hereafter existing. 2.2 Board. "Board" means the Board of Directors of the Company. 2.3 Code. "Code" means the Internal Revenue Code of 1986, as amended. 2.4 Common Stock. "Common Stock" means the common stock of the Company. 2.5 Continuous Service. "Continuous Service" means that Holder's service with the Company or an Affiliate, whether as an employee or consultant, is not interrupted or terminated. Holder's Continuous Service shall not be deemed to have terminated merely because of a change in the capacity in which Holder renders service to the Company or an Affiliate as an employee or consultant or a change in the entity for which Holder renders such service, provided that there is no interruption or termination of Holder's Continuous Service. For example, a change in status from an employee of the Company to a consultant of an Affiliate will not constitute an interruption of Continuous Service. The Board, in its sole discretion, may determine whether Continuous Service shall be considered interrupted in the case of any leave of absence approved by the Board, including sick leave, military leave or any other personal leave. 2.6 Disability. "Disability" means the permanent and total disability of Holder within the meaning of Section 22(e)(3) of the Code. 2.7 Expiration Date. "Expiration Date" means May 29, 2011. 2.8 Fair Market Value. "Fair Market Value" means, as of any date, the value of the Common Stock. If the Common Stock is listed on any established stock exchange or traded on the NASDAQ National Market or the NASDAQ Small Cap Market, the Fair Market Value of a share of Common Stock shall be the closing sales price for such stock (or the closing bid, if no sales were reported) as quoted on such exchange or market (or the exchange or market with the greatest volume of trading in the Common Stock) on the day of determination or, if the day of determination is not a market trading day, then on the last market trading day prior to the day of determination, as reported in The Wall Street Journal or such other source as the Board deems reliable. In the absence of such markets for the Common Stock, the Fair Market Value shall be determined in good faith by the Board. 2.9 Securities Act. "Securities Act" means the Securities Act of 1933, as amended. 2.10 Vesting Commencement Date. "Vesting Commencement Date" shall mean Holder's first day of continuous service with the Company. 3. VESTING. Subject to the limitations contained herein, the Option will vest and become exercisable with respect to 25% of the Option Shares on the first anniversary of the Vesting Commencement Date and with respect to the remaining Option Shares in equal monthly installments over the three years following the Vesting Commencement Date; provided that vesting will cease upon the termination of Holder's Continuous Service. 4. METHOD OF PAYMENT OF THE EXERCISE PRICE. Payment of the Exercise Price is due in full upon exercise of all or any part of the Option. Holder may elect to make payment of the Exercise Price in cash or by check or one or more of the following if the Company, in its sole discretion at the time the Option is exercised, is then offering such alternatives: (a) Provided that at the time of exercise the Common Stock is publicly traded and quoted regularly in The Wall Street Journal, then pursuant to a program developed under Regulation T as promulgated by the Federal Reserve Board which, prior to the issuance of Common Stock, results in either the receipt of cash (or check) by the Company or the receipt of irrevocable instructions to pay the aggregate exercise price to the Company from the sales proceeds (a "cashless exercise"). (b) Provided that at the time of exercise the Common Stock is publicly traded and quoted regularly in The Wall Street Journal, then by delivery of already-owned shares of Common Stock (valued at their Fair Market Value on the date of exercise) if (i) either Holder has held the already-owned shares for the period required to avoid a charge to the Company's reported earnings (generally six months) or Holder did not acquire the already-owned shares, directly or indirectly from the Company and (ii) Holder owns the already-owned shares free and clear of any liens, claims, encumbrances or security interests. "Delivery" for these purposes, in the sole discretion of the Company at the time the Option is exercised, shall include delivery to the Company of Holder's attestation of ownership of such shares of Common Stock in a form approved by the Company. Notwithstanding the foregoing, the Option may not be exercised by tender to the Company of Common Stock to the extent such tender would constitute a violation 2 of the provisions of any law, regulation or agreement restricting the redemption of the Company's stock. (c) Provided there has been a change in control described in Section 9(c) and the surviving corporation or acquiring corporation refuses to assume the Option or to substitute a similar option for the Option, then by authorizing the Company to withhold shares from the shares of the Common Stock otherwise issuable to Holder as a result of the exercise of the Option. Notwithstanding the foregoing, the Option may not be exercised by withholding shares of Common Stock to the extent such withholding would constitute a violation of the provisions of any law, regulation or agreement restricting the redemption of the Company's stock. 5. WHOLE SHARES. The Option may only be exercised for whole shares. 6. SECURITIES LAW COMPLIANCE. Notwithstanding anything to the contrary contained herein, the Option may not be exercised unless the shares issuable upon exercise of the Option are then registered under the Securities Act or, if such shares are not then so registered, the Company has determined that such exercise and issuance would be exempt from the registration requirements of the Securities Act. The exercise of the Option must also comply with other applicable laws and regulations governing the Option, and the Option may not be exercised if the Company determines that the exercise would not be in material compliance with such laws and regulations. 7. TERM. The term of the Option commences on the Grant Date and expires upon the EARLIEST of the following: (a) three (3) months after the termination of Holder's Continuous Service for any reason other than death or Disability, provided that if during any part of such three-month period the Option is not exercisable solely because of the condition set forth in Section 6, the Option shall not expire until the earlier of the Expiration Date or until it shall have been exercisable for an aggregate period of three (3) months after the termination of Holder's Continuous Service; (b) twelve (12) months after the termination of Holder's Continuous Service due to Disability; (c) eighteen (18) months after Holder's death if Holder dies either during Holder's Continuous Service or within three (3) months after Holder's Continuous Service terminates for reason other than Cause; (d) the Expiration Date; or (e) the tenth (10th) anniversary of the Grant Date. 3 8. EXERCISE. (a) The vested portion of the Option may be exercised during its term by delivering a Notice of Exercise in the form attached hereto as Exhibit A, together with the Exercise Price (payable in the manner set forth in Section 4) to the Secretary of the Company, or to such other person as the Company may designate, during regular business hours, together with such additional documents as the Company may then require. (b) By exercising the Option, Holder agrees that, as a condition to any exercise of the Option, the Company may require Holder to enter an arrangement providing for the payment by Holder to the Company of any tax withholding obligation of the Company arising by reason of (1) the exercise of the Option or (2) the disposition of shares acquired upon such exercise. 9. ADJUSTMENTS UPON CHANGES IN STOCK. (a) Capitalization Adjustments. If any change is made in the Common Stock without the receipt of consideration by the Company (through merger, consolidation, reorganization, recapitalization, reincorporation, stock dividend, dividend in property other than cash, stock split, liquidating dividend, combination of shares, exchange of shares, change in corporate structure or other transaction not involving the receipt of consideration by the Company), the number of Option Shares and the Exercise Price will be appropriately adjusted by the Board, whose determination shall be final, binding and conclusive. (The conversion of any convertible securities of the Company shall not be treated as a transaction "without receipt of consideration" by the Company.) (b) Change in Control--Dissolution or Liquidation. In the event of a dissolution or liquidation of the Company, the Option shall be terminated if not exercised (if applicable) prior to such event. (c) Change in Control--Asset Sale, Merger, Consolidation or Reverse Merger. (i) The Option will immediately vest 100% in the event of a change in control of the Company consisting of: (1) a sale of substantially all of the assets of the Company, (2) a merger or consolidation in which the Company is not the surviving corporation or (3) a reverse merger in which the Company is the surviving corporation but the shares of Common Stock outstanding immediately preceding the merger are converted by virtue of the merger into other property, whether in the form of securities, cash or otherwise. If applicable, the time during which the Option may be exercised shall also be accelerated in full. The Option shall terminate if not exercised (if applicable) at or prior to such event, and any surviving corporation or acquiring corporation shall assume the remaining unvested portion of the Option or shall substitute a similar Option. 4 (ii) For purposes of subsection 9(c) the Option shall be deemed assumed if, following the change in control, the Option confers the right to purchase, in accordance with its terms and conditions, for each share of Common Stock subject to the Option immediately prior to the change in control, the consideration (whether stock, cash or other securities or property) to which a holder of a share of Common Stock on the effective date of the change in control was entitled. 10. TRANSFERABILITY. The Option is not transferable, except by will or by the laws of descent and distribution, and is exercisable during Holder's life only by Holder. Notwithstanding the foregoing, by delivering written notice to the Company, in a form satisfactory to the Company, Holder may designate a third party who, in the event of Holder's death, shall thereafter be entitled to exercise the Option. 11. NOT A SERVICE CONTRACT. This Agreement is not an employment or service contract, and nothing in this Agreement shall be deemed to create in any way whatsoever any obligation on Holder's part to continue in the employ of the Company, or of the Company to continue Holder's employment. In addition, nothing in this Agreement shall obligate the Company, its shareholders, Board, officers or employees to continue any relationship that Holder might have as a director or consultant for the Company. 12. WITHHOLDING OBLIGATIONS. (a) At the time the Option is exercised, in whole or in part, or at any time thereafter as requested by the Company, Holder hereby authorizes withholding from payroll and any other amounts payable to Holder, and otherwise agrees to make adequate provision for (including by means of a "cashless exercise" pursuant to a program developed under Regulation T as promulgated by the Federal Reserve Board to the extent permitted by the Company), any sums required to satisfy the federal, state, local and foreign tax withholding obligations of the Company, which arise in connection with the Option. (b) The Option is not exercisable unless the tax withholding obligations of the Company are satisfied. Accordingly, Holder may not be able to exercise the Option when desired even though the Option is vested. 13. NO RIGHTS AS A SHAREHOLDER. The Option shall not entitle the Holder to any cash dividend, voting or other right of a shareholder unless and until the date of issuance of the shares that are the subject of the Option. 14. PROFESSIONAL ADVICE. The acceptance and exercise of the Option and the sale of Option Shares has consequences under federal and state tax and securities laws which may vary depending upon the individual circumstances of the Holder. Accordingly, Holder acknowledges that he has been advised to consult his personal legal and tax advisor in connection with this Agreement and his dealings with respect to the Option and the Option Shares. Holder further acknowledges that the Company has made no warranties or representations to Holder with respect to the income tax consequences of the grant and exercise of the Option or the sale of the 5 Option Shares and Holder is in no manner relying on the Company or its representatives for an assessment of such consequences. 15. ASSIGNMENT; BINDING EFFECT. Subject to the limitations set forth in this Agreement, this Agreement shall be binding upon and inure to the benefit of the executors, administrators, heirs, legal representatives, and successors of the parties hereto; provided, however, that Holder may not assign any of Holder's rights under this Agreement. 16. DAMAGES. Holder shall be liable to the Company for all costs and damages, including incidental and consequential damages, resulting from a disposition of Option Shares which is not in conformity with the provisions of this Agreement. 17. GOVERNING LAW. This Agreement shall be governed by, and construed in accordance with, the laws of the State of Washington excluding those laws that direct the application of the laws of another jurisdiction. 18. NOTICES. All notices and other communications under this Agreement shall be in writing.
