PART I

ITEM 1. BUSINESS.

DESCRIPTION OF BUSINESS

F5 is a leading provider of integrated Internet traffic and content management solutions designed to improve the availability and performance of Internet-based servers and applications. Our products monitor and manage local and geographically dispersed servers and intelligently direct traffic to the server best able to handle a user's request. Our content management products enable network managers to increase access to content by capturing and storing it at points between production servers and end-users and ensure that newly published or updated files and applications are replicated uniformly across all target servers. When combined with our network management tools, these products help organizations optimize their network server availability and performance and cost-effectively manage their Internet infrastructure.

Certain statements under the captions "Risk Factors," "Management's Discussion and Analysis of Financial Condition and Results of Operations" and "Business," and elsewhere in this report are "forward-looking statements." These forward-looking statements include, but are not limited to, statements about our plans, objectives, expectations and intentions and other statements contained in this report that are not historical facts. When used in this report, the words "expects," "anticipates," "intends," "plans," "believes," "seeks," "estimates" and similar expressions are generally intended to identify forward-looking statements. Because these forward-looking statements involve risks and uncertainties, there are important factors that could cause actual results to differ materially from those expressed or implied by these forward-looking statements, including our plans, objectives, expectations and intentions and other factors discussed under "Risk Factors."

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. Network infrastructures are further strained by unpredictable traffic, the complexity of the network environment and the increased variety of data, including multimedia components and video clips. At the same time, the complexity and volume of Internet traffic has increased dramatically.

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, 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 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.

3

Currently, many available Internet traffic and content management products are extensions of hardware-based routers, 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 who 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

We develop, market and support intelligent, cost-effective, integrated Internet traffic and content management solutions designed to ensure that content and applications on Internet-based servers are continuously and readily available. 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 an integrated solution, our products are designed to 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.

                                           geographically dispersed Internet sites

EDGE-FX(TM) Cache...................       High performance cache server for fast          August 2000
                                           delivery of Internet content

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 Web 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. 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.

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,

6

cookie, or location of the cookie -- providing intelligent, granular management of web sites without performance degradation.

Additional BIG-IP features include:

- Secure sockets layer (SSL) 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.

- Secure server protection protects against unauthorized use of the network server array.

- Rate shaping allows priority levels to be assigned to specific types of traffic.

- Packet filtering enables content providers to direct network traffic to servers based on criteria set by network managers.

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.

SEE-IT Network Manager. SEE-IT is a software application that communicates with BIG-IP and 3-DNS to help improve the management and functionality of an organization's network servers. SEE-IT, which runs on an NT server, uses real-time data collected by BIG-IP and 3-DNS to perform 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 comes pre-loaded with BIG-IP and 3-DNS and 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 BIG-IP to project future network and server needs. Network managers and system administrators can use these tools to

7

create "what if?" scenarios to help forecast the need for additional servers, interface upgrades and other network capacity requirements.

GLOBAL-SITE Controller. GLOBAL-SITE, a global data delivery appliance, has been designed to help organizations automate the distribution and synchronization of file-based content and applications to local and geographically dispersed Internet sites. GLOBAL-SITE was developed to work with our other products to provide an integrated Internet traffic and content management solution. GLOBAL-SITE consists of our proprietary software, which is loaded on a preconfigured, industry-standard hardware platform and was developed to intelligently deploy both program and data files to arrays of heterogeneous Web servers. GLOBAL-SITE's configuration database allows administrators to define standard rules for content deployment as well as accommodate unique content distribution events as needed.

EDGE-FX Cache. EDGE-FX is a price/performance 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 other traffic and content management products, EDGE-FX enables customers to implement end-to-end content delivery solutions.

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

- Forward Proxy is 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.

- Transparent Forward Proxy, when combined with BIG-IP or a Layer 4 switch, EDGE-FX can be deployed as a transparent proxy cache, automatically examining each request without the need to reconfigure Web browsers.

- Reverse Proxy, when deployed in front of web servers for external user access, EDGE-FX transfers client requests from the Web server, eliminating the danger of server traffic surges. EDGE-FX can also lower overall costs by conserving access to origin servers and bandwidth.

Designed for massive scalability, multiple EDGE-FX 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.

PRODUCT DEVELOPMENT

We believe that our future success depends on our ability to build upon our current technology platform, expand the features and functionalities of our suite of Internet traffic and content management products and develop additional products that maintain our technological competitiveness. Our product development group, which is divided along product lines, employs a standard process for the design, development, documentation and quality control of our Internet traffic and content management solutions. Each product line is headed by a lead architect, who is responsible for developing the technology behind the product. To help develop the technology, the lead architects work closely with our customers to better understand their requirements. Software engineers who help design and build the products, and technicians, who perform test engineering, configuration management, quality assurance and documentation functions, complete our product development teams. The test engineering team evaluates the overall quality of our products and determines whether they are ready for release.

8

Our product development expenses for fiscal 2000, 1999 and 1998 were $14.5 million, $5.6 million and $1.8 million, respectively. We expect our product development expenses to increase as we hire additional research and development personnel to develop new products and upgrade our existing ones.

CUSTOMERS

Our target customers include Internet service providers, companies with large e-commerce sites and high-traffic Internet or intranet Web sites. We have sold our products directly or through resellers to over 2,500 end-customers as of September 30, 2000. Our largest reseller, Exodus Communications, accounted for 14% of our net revenues for the year ended September 30, 2000. During the fourth quarter of fiscal 2000 ended September 30, no single customer or reseller accounted for more than 10% total sales.

SALES AND MARKETING

We market and sell our Internet traffic and content management solutions on a global basis through direct sales and channel partners. We plan to continue investing significant resources to expand our direct sales force and further develop our indirect sales channels by developing relationships with leading industry resellers, original equipment manufacturers, systems integrators, Internet service providers and other channel partners. Typically, our agreements with our channel partners are not exclusive and do not prevent our channel partners from selling competitive products. These agreements typically have terms of one or two years with no obligation to renew, and typically do not provide for exclusive sales territories or minimum purchase requirements.

Exodus and Frontier GlobalCenter account for most of our indirect sales. We are in the process of seeking channel partners for our products in the United States and selected countries in the European, Asia Pacific and South American markets. We have increased, and plan to further increase, the number of individuals focused on sales to government entities, and are developing strategic relationships that will help facilitate these sales.

Our domestic sales managers are located in Atlanta, Boston, Chicago, Dallas, Los Angeles, New York, San Francisco, Seattle, and Washington D.C. Our international sales managers are located in Australia, Canada, China, Germany, Hong Kong, India, Japan, Korea, Malaysia, Singapore and the United Kingdom. The inside sales team generates and qualifies leads for our regional sales managers and help manage accounts by serving as a liaison between our field and internal corporate resources. Our field systems engineers also support our regional sales managers by participating in joint sales calls and providing pre-sale technical resources as needed.

Our marketing programs are focused on creating awareness of our Internet traffic and content management solutions targeted at information technology professionals such as chief information officers. We plan to continue building strong brand awareness to leverage the value of our Internet traffic and content management products and professional services in the marketplace. We believe brand visibility is a key factor in increasing customer awareness, and our goal is for the F5 brand to be synonymous with superior performance, high quality customer service and ease of use. We market our products and services through a broad range of marketing programs, including active tradeshow participation, advertising in print publications, direct marketing, high-profile Web events and our Internet site.

PROFESSIONAL SERVICES AND TECHNICAL SUPPORT

We believe that our ability to consistently provide high-quality customer service and support will be a key factor in attracting and retaining customers. 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 go on-site to help with installation and provide an initial training session 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

9

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 three 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, service, and warranty. Our principal competitors in the Internet traffic and content management market include CacheFlow, Cisco Systems, Extreme Networks, Foundry Networks, Inktomi, Network Applicance, Nortel Networks, RadWare and Resonate.

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 and performance 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 10 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, 2000, we employed 496 full-time persons, 134 of whom were engaged in product development, 176 in sales and marketing, 111 in professional services and technical support and 75 in finance, administration and operations. None of our employees are represented by a labor union and we have not experienced any work stoppages to date. We consider our employee relations to be good.

OVERVIEW

F5 was incorporated on February 26, 1996 and began operations in April 1996. Our fiscal year ended on September 30, 2000.

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 $31.5 million, net of offering costs.

For the fiscal years 1998 through 2000, our net revenues were $4.9 million, $27.8 million and $108.6 million respectively. We achieved our first quarterly profit during the fourth quarter of fiscal year 1999 and our first annual profit in fiscal year 2000.

Currently, we derive approximately 62% of our net revenues from sales of BIG-IP, and we expect to derive a significant portion of our net revenues from sales of BIG-IP in the future. During fiscal year 2000, one of our resellers, Exodus Communications, accounted for 14% of our net revenues and 8% of our accounts receivable balance at September 30, 2000.

Net revenues derived from customers located outside of the United States were $20.6 million in fiscal 2000, $2.2 million in fiscal 1999, and $172,000 in fiscal 1998. We plan to continue expanding our international operations significantly, particularly in selected countries in the European and Asia Pacific markets, because we believe international markets represent a significant growth opportunity.

Customers who purchase our products have the option to receive 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.

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.

Our ordinary payment terms to our domestic customers are net 30 days, but we have extended payment terms beyond net 30 days to some customers. For these arrangements, revenue is recognized ratably over the terms of the arrangement. Our ordinary payment terms to our international customers are net 60 days.

In view of the rapidly changing nature of our business and our limited operating history, we believe that period-to-period comparisons of net revenues and operating results are not necessarily meaningful and should not be relied upon as indicators of future performance. To maintain profitability we will need to increase our net revenues and manage operating expenses. Although we have experienced rapid growth in net revenues in recent periods, we may not be able to sustain these growth rates to maintain profitability.

We have recorded a total of $8.2 million of stock compensation costs since our inception through September 30, 2000. 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 $2.1 million, $2.5 million and $420,000 for the years ended September 30, 2000, 1999 and 1998, respectively.

We expect to recognize amortization expense related to unearned compensation of approximately $2.2 million, $824,000, $60,000 and $0 during the years ended September 30, 2001, 2002, 2003 and 2004, 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.

YEARS ENDED SEPTEMBER 30, 2000 AND 1999

Net Revenues:

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

Product revenues. Product revenues increased by 275.7%, from $23.4 million for the year ended September 30, 1999 to $88.0 million for the year ended September 30, 2000. This increase in product revenues was due to an increase in the quantity of our products sold, primarily through our indirect sales channels and to a lesser extent through our direct sales channels.

Service revenues. Service revenues increased by 369.1%, from $4.4 million for the year ended September 30, 1999 to $20.7 million for the year ended September 30, 2000. This increase was due primarily to an increase in the installed base of our products and the renewal of service and support contracts.

International revenues represented 7.7% of total revenues for the year ended September 30, 1999 and 19% of total revenues for the year ended September 30, 2000. This increase represents the growth in demand for our products and an increase in the number of resellers. We expect international revenues to continue to represent a significant portion of net revenues, although we cannot assure you that these revenues as a percentage of net revenues will remain at current levels. All sales transactions are denominated in U.S. dollars.

As our net revenue base increases, we do not believe we can sustain percentage growth rates of net revenues that we have experienced historically.

Cost of Net Revenues:

Cost of net revenues consists primarily of outsourced hardware components and manufacturing, 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 341.8%, from $5.6 million for the year ended September 30, 1999 to $24.7 million for the year ended September 30, 2000. Cost of product revenues increased as a percent of product revenues from 23.8% for the year ended September 30, 1999, to 28.0% for the year ended September 30, 2000. The increase as a percentage of product revenues was the result of higher production costs associated with hardware configuration enhancements. The cost of raw materials may increase, which would cause the cost of product revenues to increase and have a negative impact on our gross margin.

Cost of service revenues. Cost of service revenues increased 388.9%, from $1.6 million for the year ended September 30, 1999 to $7.9 million for the year ended September 30, 2000. Cost of service revenues increased as a percent of service revenues from 36.7% for the year ended September 30, 1999 to 38.3% for the year ended September 30, 2000. The increase in cost of service revenue as a percentage of service revenues is due to increased personnel costs which include training and consulting.

Sales and marketing. Our 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 173.2%, from $13.5 million for the year ended September 30, 1999 to $36.9 million for the year ended September 30, 2000. This increase was due to an increase in sales and marketing personnel and professional services personnel from 93 to 287, and increased advertising and promotional activities. We expect to continue increasing sales and marketing expenses in order to grow net revenues and expand our brand awareness.

Research and development. Our 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.

18

Research and development expenses increased by 156.6%, from $5.6 million for the year ended September 30, 1999 to $14.5 million for the year ended September 30, 2000. This increase was due to an increase in product development personnel from 59 to 134 and nonrecurring charges of $1.6 million consisting of prototype material expenses and a one time licensing agreement. 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 increase in future periods.

General and administrative. Our 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 151.4%, from $3.9 million for the year ended September 30, 1999 to $9.7 million for the year ended September 30, 2000. This increase was due primarily to an increase in general and administrative personnel from 35 to 75 and a one time executive recruitment charge of $1.6 million. We expect general and administrative expenses to increase as we expand our staff, further develop our internal information systems and incur costs associated with being a publicly held company.

Unearned compensation. We recorded stock compensation charges of $2.5 million and $2.1 million for the years ended September 30, 1999 and 2000, respectively.

Other income (expense), net. Other income consists primarily of earnings on our cash and cash equivalents balances. Interest income was $534,000 for the year ended September 30, 1999 and $3.2 million for the year ended September 30, 2000. There was a one time asset impairment charge of $336,000, associated with the move to our new corporate headquarters.

Income taxes. The income tax provision increase from zero in fiscal 1999 to $2.1 million in fiscal 2000. The Company utilized a portion of its U.S. federal and state net operating loss carryforwards in fiscal 2000. The difference between the statutory rate and the effective rate was due primarily to previous unrecognized deferred tax assets. FASB statement No. 109 provides for the recognition of deferred tax assets if realization is more likely than not. Based on available evidence, which includes our historical operating performance and the reported cumulative net losses in all prior years, we historically provided for a full valuation allowance against our net deferred tax assets. Based on our operating performance, we determined that a certain portion of these assets are more likely than not to be realizable. As a result, the valuation allowance has been partially reversed against our net deferred assets for these assets which are considered realizable. We have maintained a valuation allowance on our remaining net operating loss carryforwards as of September 30, 2000 (approximately $4.9 million). These remaining net operating loss carryforwards primarily relate to the tax benefits associated with our stock option plans, which will be offset against shareholders' equity.

YEARS ENDED SEPTEMBER 30, 1999 AND 1998

Net Revenues:

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

Product revenues. Product revenues increased by 468.6%, from $4.1 million for the year ended September 30, 1998 to $23.4 million for the year ended September 30, 1999. This increase in product revenues was due to an increase in the quantity of our products sold, primarily through our indirect sales channels and to a lesser extent through our direct sales channels.

Service revenues. Service revenues increased by 472.1%, from $770,000 for the year ended September 30, 1998 to $4.4 million for the year ended September 30, 1999. This increase was due primarily to an increase in the installed base of our products and the renewal of service and support contracts.

19

Cost of Net Revenues:

Cost of net revenues consists primarily of outsourced hardware components and manufacturing, 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 411.6%, from $1.1 million for the year ended September 30, 1998 to $5.6 million for the year ended September 30, 1999. Cost of product revenues decreased as a percent of product revenues from 26.5% for the year ended September 30, 1998, to 23.8% for the year ended September 30, 1999. The decrease as a percentage of product revenues was the result of higher utilization of manufacturing operations, including increased economies of scale achieved from an increase in production. The increase in absolute dollars was due primarily to an increase in product revenues. The cost of raw materials may increase, which would cause the cost of product revenues to increase and have a negative impact on our gross margin.

Cost of service revenues. Cost of service revenues increased 415.3%, from $314,000 for the year ended September 30, 1998 to $1.6 million for the year ended September 30, 1999. Cost of service revenues decreased as a percent of service revenues from 40.8% for the year ended September 30, 1998 to 36.7% for the year ended September 30, 1999. The decrease in cost of service as a percentage of service revenues is due to increased economies of scale achieved from increased service revenues. The increase in cost of service revenues in absolute dollars was due primarily to increased personnel costs which include training and consulting.

Sales and marketing. Our 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 248.0%, from $3.9 million for the year ended September 30, 1998 to $13.5 million for the year ended September 30, 1999. This increase was due to an increase in sales and marketing personnel and professional services personnel from 37 to 93, and increased advertising and promotional activities. We expect to continue increasing sales and marketing expenses in order to grow net revenues and expand our brand awareness.

Research and development. Our 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 211.7%, from $1.8 million for the year ended September 30, 1998 to $5.6 million for the year ended September 30, 1999. This increase was due to an increase in product development personnel from 27 to 59. 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 increase in future periods.

General and administrative. Our 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 271.7%, from $1.0 million for the year ended September 30, 1998 to $3.9 million for the year ended September 30, 1999. This increase was due primarily to an increase in general and administrative personnel from 16 to 35. We expect general and administrative expenses to increase as we expand our staff, further develop our internal information systems and incur costs associated with being a publicly held company.

Unearned compensation. We recorded stock compensation charges of $420,000 and $2.5 million for the years ended September 30, 1998 and 1999, respectively.

Interest income (expense) net. Interest income consists of earnings on our cash and cash equivalent balances offset by interest expense associated with debt obligations. Net interest expense was $4,000 for the year ended September 30, 1998 compared to net interest income of $534,000 for the year ended September 30, 1999. This increase was due primarily to the investment of the proceeds received from our initial public offering in June 1999.

20

Income taxes. As of September 30, 1999, we had approximately $7.8 million of net operating loss carryforwards for federal income tax purposes. Accordingly, there was no provision for federal or state income taxes for any prior period. Utilization of the net operating loss carryforwards may be subject to annual limitations due to the ownership change limitations contained in the Internal Revenue Code of 1986 and similar state provisions. Annual limitations may result in the expiration of the net operating losses before we can utilize them. The federal net operating loss carryforwards will expire at various dates beginning in 2011 through 2019 if we do not use them.

Our quarterly operating results have fluctuated significantly and we expect that future operating results will be subject to similar fluctuations for a variety of factors, many of which are substantially outside our control. See "Risk Factors-Our quarterly operating results are volatile and may cause our stock price to fluctuate."

LIQUIDITY AND CAPITAL RESOURCES

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.

Cash used in our operating activities was $2.0 million for the year ended September 30, 1999. Cash provided by our operating activities was $9.8 million for the year ended September 30, 2000. Net cash for fiscal year 2000 outflows resulted from increases in accounts receivable due to increased sales and other current assets and were partially offset by increases in accounts payable, accrued liabilities and deferred revenues. Net cash inflows for fiscal year 2000 was the result of the Company becoming profitable in the second quarter of 2000. We anticipate that in the future we may offer financing to certain resellers. To the extent such financing is offered, cash used in operating activities will increase to fund the increase in outstanding accounts receivable.

Cash used in investing activities was $5.6 million for the year ended September 30, 1999 and $16.5 million for the year ended September 30, 2000, which includes $13.3 million used to purchase property and equipment and $3.2 million used to invest in restricted cash. The components of restricted cash consist of an irrevocable standby letters of credit, totaling $6.0 million to fund our commitment to lease office space.

As of September 30, 1999, 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. The company established a restricted escrow account in connection with this lease agreement. Under the term of the lease, a $6 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. Although we have no other material commitments, we anticipate a substantial 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 June 1998, the FASB issued Statement of Financial Accounting Standards No. 133, "Accounting for Derivative Instruments and Hedging Activities." This statement requires that all derivative instruments be recorded on the balance sheet at their fair value. Changes in the fair value of derivatives are recorded each period in current earnings or other comprehensive income, depending on whether a derivative is designated as part of a hedge transaction and, if it is, the type of hedge transaction. In July 1999, the FASB issued SFAS No. 137, "Accounting for Derivative Instruments and Hedging Activities Deferral of the Effective Date of FASB Statement No. 133." SFAS No. 137 deferred the effective date of SFAS No. 133 until fiscal years beginning after June 15, 2000. The Company does not use derivative instruments, therefore the adoption of this statement will not have any effect on the Company's results of operations or its financial position.

In December 1999, SEC Staff Accounting Bulletin No. 101 ("SAB 101"), "Revenue Recognition in Financial Statements," was issued. This pronouncement summarizes certain of the SEC staff's views in applying generally accepted accounting principles to revenue recognition. SAB 101 is required to be adopted by the

23

Company for the year ended September 30, 2001. The Company is currently reviewing the requirements of SAB 101 and assessing its impact on the Company's financial statements.

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
(loss) will decrease (increase) 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 SUCCESS DEPENDS ON SALES OF OUR BIG-IP(R).

We currently derive approximately 62% 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. We are currently developing new features for our existing products. We expect to continue to develop new products and new product features in the future. If we fail to develop and deploy new products and new product features on a timely basis, 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, Nortel Networks, RadWare and Resonate. 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."

24

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 19% of our net revenues for the year ended September 30, 2000, 7.7% of our net revenues for the year ended September 30, 1999, and 3.5% for the year ended September 30, 1998. We have engaged sales personnel in Australia, Europe, Asia Pacific and Latin America. 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.

WE MAY NOT BE ABLE TO SUSTAIN OR DEVELOP NEW DISTRIBUTION RELATIONSHIPS.

Our sales strategy requires that we establish multiple 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. One of our resellers, Exodus Communications, accounted for 14% of our net revenues for the year ended September 30, 2000, and 8% of our accounts receivable balance at September 30, 2000. Our inability to effectively establish our indirect sales channels will seriously harm our business and results of operations.

OUR SUCCESS DEPENDS ON OUR ABILITY TO ATTRACT, TRAIN AND RETAIN QUALIFIED MARKETING AND SALES, PROFESSIONAL SERVICES AND CUSTOMER SUPPORT PERSONNEL.

Our products require a sophisticated marketing and sales effort targeted at several levels within a prospective customer's organization. Competition for qualified sales personnel is intense, and we might not be able to hire the kind and number of sales personnel we are targeting. Our inability to retain and hire qualified sales personnel may seriously harm our business and results of operations.

We currently have a professional services and customer support organization and will need to increase our staff to support new customers and the expanding needs of existing customers. The installation of Internet traffic and content management solutions, the integration of these solutions into existing networks and the ongoing support can be complex. Accordingly, we need highly-trained professional services and customer support personnel. Hiring professional services and customer support personnel is very competitive in our industry due to the limited number of people available with the necessary technical skills and understanding of our products. Our inability to attract, train or retain the number of highly qualified professional services and customer support personnel that our business needs may seriously harm our business and results of operations.

WE DEPEND ON OUR KEY PERSONNEL AND THE LOSS OF ANY KEY PERSONNEL MAY HARM OUR BUSINESS AND RESULTS OF OPERATIONS.

Our success depends to a significant degree upon the continued contributions of our key management, product development, sales and marketing and finance personnel, many of whom will be difficult to replace. The loss of services of any of our key personnel may seriously harm our business and results of operations. We do not have employment contracts with any of our key personnel.

IT IS DIFFICULT TO PREDICT OUR FUTURE OPERATING RESULTS BECAUSE WE HAVE AN UNPREDICTABLE SALES CYCLE.

We are unable to predict our sales cycle because we have limited experience selling our products. 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 on 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

25

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.

THE AVERAGE SELLING PRICES 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.

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."

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.

26

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. Although we have not been a party to any claims alleging infringement of intellectual property rights, we cannot assure you that we will not be subject to these claims in the future. 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 noninfringing 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.

LAWS RELATING TO ENCRYPTED SOFTWARE MAY LIMIT THE MARKETABILITY OF OUR PRODUCTS.

The encryption technology contained in our products is subject to United States export controls. These export controls limit our ability to distribute encrypted software outside of the United States and Canada. While we take precautions against unlawful exportation, this exportation inadvertently may have occurred in the past or may occur from time to time in the future, subjecting us to potential liability and serious harm. We may also encounter difficulties competing with non-United States producers of products containing encrypted software, who may both import their products into the United States and sell products overseas.

27

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. 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.

                                                                                 MATURING IN

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, 2000 and expect to continue to do so, we do not anticipate that foreign exchange gains or losses will be significant. We have not engaged in foreign currency hedging to date, however we may do so in the future.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

PRINCIPLES OF CONSOLIDATION

The financial statements consolidate the accounts of F5 Networks, Inc. and its wholly owned subsidiaries F5 Networks, Ltd., F5 Networks, Singapore Pte. Ltd. and F5 Networks, Japan K.K. The companies are collectively hereinafter referred to as the "Company". All intercompany transactions have been eliminated.

SEGMENT INFORMATION

The Company has adopted Statement of Financial Accounting Standards No. 131, "Disclosures about Segments of an Enterprise and Related Information" ("SFAS No. 131"). SFAS No. 131 supersedes Statement of Financial Accounting Standards No. 14, "Financial Reporting for Segments of a Business Enterprise," replacing the "industry segment" approach with the "management" approach. The management approach designates the internal organization that is used by management for making operating decisions and assessing performance as the source of the Company's reportable segments. SFAS No. 131 also requires disclosures about products and services, geographic areas, and major customers.

USE OF ESTIMATES

The preparation of financial statements in conformity with generally accepted accounting principles 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.

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 and cash equivalents balance consists of the following:

CONCENTRATION OF CREDIT RISK

The Company places its temporary cash investments with 4 major financial institutions.

The Company's customers are from diverse industries and geographic locations. Net revenues from international customers are denominated in U.S. Dollars and were approximately $20,598,000, $2,153,000 and $172,000 for the years ended September 30, 2000, 1999 and 1998, respectively. One customer accounted for 14% and 22% of net revenues for the years ended September 30, 2000 and 1999, respectively. For the year ended September 30, 1998 no single customer accounted for more than 10% of the Company's net revenues. One customer represented 8% and 16% of accounts receivable for the years ended September 30, 2000 and 1999 respectively. 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, software and 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 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. Equipment under capital leases is stated at the lower of the present value of the minimum lease payments discounted at the Company's incremental borrowing rate at the beginning of the lease term or fair value at the inception of the lease. 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 two years.

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 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

36

F5 NETWORKS, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

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 software revenue under Statement of Position 97-2, "Software Revenue Recognition," and SOP 98-9 "Modification of SOP 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. The Company generally combines software license, installation and customer support elements into a package with a single "bundled" price. The Company 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 is a breakdown of revenues by shipment destination for the years ended 2000, 1999 and 1998:

                               SEPTEMBER 30,

                   ========      ========      ========

WARRANTY EXPENSE

The Company offers product warranties of generally 90 days. 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, 2000, 1999 and 1998 warranty expense was $2,319,000, $309,000 and $83,000 respectively.

ADVERTISING

Advertising costs are expensed as incurred. Advertising expense was approximately $1,614,000, $992,000 and $256,000 for the years ended September 30, 2000, 1999 and 1998, 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 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. During 2000 and 1999 the Company charged to operations $(84,000) and $2,000, respectively, resulting from such transactions.

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. 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.

NET INCOME (LOSS) PER SHARE

In accordance with SFAS No. 128, basic net income (loss) per share has been computed using the weighted-average number of shares of common stock outstanding during the period, except that pursuant to Securities and Exchange Commission Staff Accounting Bulletin No. 98, if applicable, common shares issued presented for nominal consideration in each of the periods have been included in the calculation as if they were outstanding for all periods presented.

38

F5 NETWORKS, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

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 following table sets forth the computation of basic and diluted net income (loss) per share for the years ended September 30, 2000, 1999 and 1998.

                                                                           YEAR ENDED SEPTEMBER 30,

NEW ACCOUNTING PRONOUNCEMENTS

In June 1998, the FASB issued Statement of Financial Accounting Standards No. 133, "Accounting for Derivative Instruments and Hedging Activities." This statement requires that all derivative instruments be recorded on the balance sheet at their fair value. Changes in the fair value of derivatives are recorded each period in current earnings or other comprehensive income, depending on whether a derivative is designated as part of a hedge transaction and, if it is, the type of hedge transaction. In July 1999, the FASB issued SFAS No. 137, "Accounting for Derivative Instruments and Hedging Activities Deferral of the Effective Date of FASB Statement No. 133." SFAS No. 137 deferred the effective date of SFAS No. 133 until fiscal years beginning after June 15, 2000. The Company does not use derivative instruments, therefore the adoption of this statement will not have any effect on the Company's results of operations or its financial position.

In December 1999, SEC Staff Accounting Bulletin No. 101 ("SAB 101"), "Revenue Recognition in Financial Statements," was issued. This pronouncement summarizes certain of the SEC staff's views in applying generally accepted accounting principles to revenue recognition. SAB 101 is required to be adopted by the Company for the year ended September 30, 2001. The Company is currently reviewing the requirements of SAB 101 and assessing its impact on the Company's financial statements.

The Company's deferred tax assets include net operating loss carryforwards of approximately $4.9 million. Until June 30, 2000, the Company had provided a full valuation allowance against deferred tax assets. Based upon available evidence, which include a review of historical operating performance and forecasted profitability, the Company determined that certain of these deferred tax assets are more likely than not realizable and therefore has reduced the valuation allowance related to those deferred tax assets. These remaining net operating loss carryforwards of approximately $4.9 million primarily relate to the tax benefits associated with stock option plans. If these assets become recognizable, the net operating loss carryforwards related to stock option plan benefits will be offset against shareholders equity.

During fiscal year 2000, the Company recorded tax benefits related to the exercise of employee stock options in the amount of $9.8 million. These effects have been recorded to additional paid-in capital on realized benefits, and will be recorded to additional paid-in capital when net operating losses related to stock option plans reverse.

The net operating loss carryforwards and research and development tax credit carryforwards begin to expire fiscal year 2011. The company expects to utilize these carryforwards prior to expiration.

7. SHAREHOLDERS' EQUITY:

a. Preferred Stock

In April 1998, the Company issued 156,250 shares of the Company's Series C Convertible Preferred Stock and warrants to purchase 187,500 shares of the Company's common stock at $1.60 per share for an aggregate purchase price of $1.5 million. The Company has allocated approximately $75,000 of the purchase price of the Series C Convertible Preferred Stock as the value of the warrants issued. On February 1, 1999 these warrants were exercised. The holders of the Series C Convertible Preferred Stock have certain voting rights and liquidation preferences equal to $9.60 per share. Each share of Series C Convertible Preferred Stock was converted into six shares of the Company's common stock.

In August 1998, the Company issued 1,138,438 shares of Series D Redeemable Convertible Preferred Stock for an aggregate purchase price of approximately $7.7 million. The Company was required to redeem all outstanding shares of the Series D Redeemable Convertible Preferred Stock at $6.79 per share, plus all declared and unpaid

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

dividends, either in August 2005 or in three annual installments beginning August 2003 at the request of holders of at least two-thirds of the outstanding Series D Redeemable Convertible Preferred Stock. The holders of the Series D Redeemable Convertible Preferred Stock had certain voting rights and liquidation preferences equal to $13.58 per share. Each share of Series D Redeemable Convertible Preferred Stock was converted into two shares of the Company's common stock.

b. Common Stock

On December 2, 1996 and January 27, 1999 the Company authorized a 3 for 1 and 2 for 1 stock split, in the form of stock dividends, respectively on the Company's common stock. All references to number of shares and per share amounts of the Company's common stock in the accompanying financial statements and notes have been restated to reflect these stock splits.

Upon incorporation of the Company, the founding shareholders entered into an agreement (as amended, the "Shareholder Agreement") which, among other things, called for a mandatory offer to sell the shareholders' stock, first to the remaining founders, then to the Company, in the event of termination of their employment with the Company. In February 1998, one of the founders, who was also an officer of the Company, and the Company purchased 2,600,000 shares of the Company's common stock under the Shareholder Agreement from two founders who had terminated their employment. The Company facilitated the transactions between the shareholders under the Shareholder Agreement, retaining 800,000 of the repurchased shares.

c. Initial Public Offering

On June 4, 1999, the Company issued 2,860,000 shares of its common stock at an initial public offering price of $10.00 per share. Also sold in this offering were 590,000 shares held by selling shareholders, including 450,000 shares sold upon the exercise of the underwriters' overallotment option. The net proceeds to the Company from the offering, net of offering costs of approximately $3.1 million were approximately $25.5 million. Concurrent with the initial public offering, each outstanding share or the Company's convertible preferred stock was automatically converted into common stock.

d. Secondary Public Offering

In October of 1999, the Company completed and issued 500,000 shares of its common stock in a secondary public offering at a price of $67.00 per share. Also sold in this offering were 2,030,000 shares of common stock held by selling shareholders. The net proceeds to the Company, from the offering, net of offering costs of approximately $350,000 were approximately $31.5 million.

e. Warrants

In February 1999, the Company issued a warrant to purchase up to 12,500 shares of the Company's common stock at $8.00 per share to a certain customer in conjunction with a sale of products.

The Company has issued warrants to purchase common stock to a certain customer. The aggregate consideration for each respective transaction was allocated to securities or debt and the warrants based on their relative fair values. All the warrants were exercisable at the time of issuance. The assumptions applied in the determination of the fair value of warrants issued were (i) use of the Black-Scholes pricing model, (ii) risk free interest rates ranging from 5.2% to 6.2%, (iii) expected volatility rates of approximately 70% (based on disclosed expected volatility rates of comparable companies) and actual volatility subsequent to the initial public offering, (iv) assumed expected lives of 4 to 10 years, and (v) no expected dividends.

f. Equity Incentive Plans

In January 1997, Company's shareholders approved the Amended and Restated 1996 Stock Option Plan (the "1996 Employee Plan") that provides for discretionary grants of non-qualified and incentive stock options for employees and other service providers, and the Amended and Restated Directors' Nonqualified Stock Option Plan (the "1996 Directors' Plan"), which provides for automatic grants of non-qualified stock options to eligible non-employee directors. A total of 2,600,000 shares of common stock has been reserved for issuance under the 1996 Employee Plan and the 1996 Directors' Plan. Employees' stock options typically vest over a period of four years from the grant date; director options typically vest over a period of three years from the grant date. All options under the 1996 Employee Plan and the 1996 Directors' Plan expire 10 years after the grant date. This repricing was accounted for as a cancellation of existing stock options and grant of new stock options. All outstanding, unvested options under the 1996 Employee Plan and the 1996 Director's Plan vest in full upon a change in control of the Company. The Company does not intend to grant any additional options under either of these Plans.

In November 1998, the Company's shareholders adopted the 1998 Equity Incentive Plan (the "1998 Plan"), which provides for discretionary grants of non-qualified and incentive stock options, stock purchase awards and stock bonuses for employees and other service providers. A total of 3,300,000 shares of common stock have been reserved for issuance under the 1998 Plan. 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 1998 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 1998 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 terminated if not exercised before the change in control.

In April 1999, the Company's shareholders adopted the 1999 Non-Employee Directors' Stock Option Plan which provides for automatic grants to F5 non-employee directors of options to purchase shares of the Company's common stock. The board administers the plan and cannot delegate administration to a committee. The plan reserved an aggregate of 100,000 shares of common stock for issuance, subject to adjustment in the event of certain capital changes.

In July 2000, the Company's Board of Directors adopted the 2000 Employee Equity Incentive Plan (the "2000 Plan"), which provides for discretionary grants of non-qualified stock options, stock purchase awards and stock bonuses for non-executive employees and other service providers. A total of 2,000,000 shares of common stock have been reserved for issuance under the 2000 Plan. 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

44

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

options or stock awards (and the time during which these awards may be exercised) will accelerate and the options or awards terminated if not exercised before the change in control.

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 (and the time during which these awards may be exercised) will accelerate and the options or awards terminated if not exercised before the change in control.

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 $1,956,000, $4,025,000 and $1,945,000 was deferred during fiscal years 2000, 1999 and 1998, respectively, and is being amortized over the vesting period of the options, generally four years. Amortization of stock compensation costs of approximately $2,127,000, $2,487,000 and $420,000 has been recognized as an expense for the years ended September 30, 2000, 1999 and 1998, respectively.

A summary of stock option transactions are as follows:

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.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

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. The company established a restricted escrow account in connection with this lease agreement. Under the term of the lease, a $6 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.

9. 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 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 paid for, and the related portion of the loan is repaid.

10. 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. The Company's contribution will vest over a period of four years. Contributions to the plan during the years ended September 30, 2000, 1999 and 1998 were approximately $833,000, $612,000 and $0, respectively.

F5 NETWORKS, INC.
NONQUALIFIED STOCK OPTION AGREEMENT

THIS NONQUALIFIED STOCK OPTION AGREEMENT (the "Agreement") is made and entered into as of July 24, 2000 (the "Grant Date") between F5 Networks, Inc., a Washington corporation (the "Company") and John McAdam ("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 645,000 shares of the Company's Common Stock (the "Option Shares") at a price per share of $42.56 (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 July 25, 2010.


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. Unless and until Holder is notified in writing to the contrary, all notices, communications, and documents directed to the Company and related to the Agreement, if not delivered by hand, shall be mailed, addressed as follows:

F5 Networks, Inc. 501 Elliott Ave West Seattle, WA 98119

Unless and until the Company is notified in writing to the contrary, all notices, communications, and documents intended for Holder and related to this Agreement, if not delivered by hand, shall be mailed to Holder's last known address as shown on the Company's books. Notices and communications shall be mailed by first class mail, postage prepaid. All mailings and deliveries related to this Agreement shall be deemed received when actually received, if by hand delivery, and five (5) business days after mailing, if by mail.

19. AMENDMENT OF THIS AGREEMENT. The Board at any time, and from time to time, may amend the terms of this Agreement; provided, however, that the rights under this Agreement shall not be impaired by any such amendment unless
(i) the Company requests the consent of the Holder and (ii) Holder consents in writing.

(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. Unless and until Holder is notified in writing to the contrary, all notices, communications, and documents directed to the Company and related to the Agreement, if not delivered by hand, shall be mailed, addressed as follows:

F5 Networks, Inc. 501 Elliott Ave West Seattle, WA 98119

Unless and until the Company is notified in writing to the contrary, all notices, communications, and documents intended for Holder and related to this Agreement, if not delivered by hand, shall be mailed to Holder's last known address as shown on the Company's books. Notices and communications shall be mailed by first class mail, postage prepaid. All mailings and deliveries related to this Agreement shall be deemed received when actually received, if by hand delivery, and five (5) business days after mailing, if by mail.

19. AMENDMENT OF THIS AGREEMENT. The Board at any time, and from time to time, may amend the terms of this Agreement; provided, however, that the rights under this Agreement shall not be impaired by any such amendment unless
(i) the Company requests the consent of the Holder and (ii) Holder consents in writing.
