F5 Networks Forms Alliance with Network Appliance

Seattle, WA - October 7, 2002 -- F5 Networks, Inc. (NASDAQ: FFIV), the leading provider of Internet Traffic Management (ITM) products, today announced that it has formed an alliance with Network Appliance, a leading provider of network storage solutions, to provide customers with feature-rich enterprise content delivery network (ECDN) solutions.

By deploying NetApp® content delivery solutions with F5's intelligent traffic management products, customers can increase the efficiency and reduce the costs associated with the distribution of information across their network. The joint solution ensures that customers' business content is fresh, synchronized, and distributed to the right audience in a secure and timely fashion.

The key element of the F5 and Network Appliance alliance is a special, limited time, trade-in program for current F5 EDGE-FX cache customers to replace existing EDGE-FX caches with Network Appliance™ NetCache® appliances. Program details will be presented directly to qualified customers by F5 and Network Appliance sales representatives and channel partners.

"We are pleased to have a market leader like F5 Networks working so closely with us to deliver flagship ECDN solutions," said Amit Pandey, senior director of marketing and strategic alliances for content delivery solutions at Network Appliance. "Our close collaboration will benefit customers by offering them access to a powerful solution from two proven industry leaders. Both companies' products are highly complementary-F5 offers advanced local and wide-area traffic management solutions, and Network Appliance delivers industry-leading ECDN solutions. Together, we give customers the performance, management, high availability and scalability that they require for deploying next-generation Web services and applications."

"We're pleased to be working with Network Appliance where, together, we can provide enterprises with a robust, scaleable, and secure ECDN for accelerated and intelligent content delivery," said Jim Ritchings, vice president of business development at F5 Networks. "Our alliance with Network Appliance is an outcome of our recent content management strategy announcement where F5 stated that it would provide ECDN solutions through partnerships with best-of-breed content delivery and data management companies. In addition, F5's unique iControl API offers an opportunity for customers to add further value by allowing IP-based applications to monitor and control network functions across the ECDN, without human intervention."
