FORT LAUDERDALE, Fla.--(BUSINESS WIRE)--Sept. 19, 2001

By Integrating TeamSite with XPS(TM) Portal Software, Citrix

will Give Content Contributors Enhanced Control of

Portal Content Creation, Management and Collaboration Features

Citrix Systems, Inc. (Nasdaq:CTXS), a global leader in application serving and portal software and services, today announced its participation in Interwoven's (Nasdaq:IWOV) PortalReady partner program and plans to integrate Interwoven's Content Infrastructure product suite with Citrix(R) XPS(TM) portal software.

The product integration will give Citrix customers' non-technical users the ability to easily add content and update portals created with Citrix XPS, enhancing productivity and collaboration across the enterprise. Customers will access key TeamSite software features including workflow, content management categorization and multi-channel support through a Citrix Content Delivery Agent (CDA) that works directly with users' XPS portals. Citrix will use Interwoven's PortalReady SDK (Software Development Kit) to develop the integrated solution.

"Our alliance with Interwoven is a significant building block in our Internet Solutions development strategy," said Barry Davis, vice president, business development, for Citrix. "By forging ahead and developing key relationships with industry leaders like Interwoven, Citrix is giving customers even more opportunity to add greater functionality and value to their XPS deployments."

Citrix XPS portal software gives users a single, personalized and secure point of access to the applications, information and business processes they depend on to do their jobs and interact with peers within and beyond the enterprise, whether they are customers, suppliers or partners. Interwoven's Content Infrastructure offers a flexible, standards-based platform for creating, managing and deploying Web content across the enterprise.

"Citrix understands that customers work with increasingly complex and unstructured Web content that needs to be delivered to a host of computing devices and networks," said Frank Florence, senior vice president, business development at Interwoven. "We firmly believe that joint Citrix and Interwoven customers will realize the increased efficiency and value of the enterprise portal solution."

In addition to Citrix joining Interwoven's PortalReady partner program, Interwoven has also joined the Citrix Business Alliance(TM) (CBA) Internet Solutions Program.
