Citrix XPS Portal Software to Leverage SharePoint Portal Server

Companies to benefit from improved user productivity

ANAHEIM, Calif. - July 13, 2001 - At Microsoft Fusion 2001, Citrix Systems, Inc. (Nasdaq: CTXS) today announced an agreement with Microsoft enabling Citrix to leverage Microsoft® SharePoint™ Portal Server functionality with Citrix® XPS™ portal software. As part of the agreement, Citrix has joined Microsoft SharePoint Developer Community Partner Program.

"Making SharePoint Portal Server's search and document management functionality part of our portal solutions will improve user productivity through more efficient use of information sources. SharePoint Portal Server's functionality nicely complements the broad capabilities of our XML-based portal software," said Paul Hahn, director of corporate development for Citrix. "We look forward to continuing a long, fruitful relationship with Microsoft as we evolve our portal offerings and support important Microsoft initiatives like .NET."

XPS is an XML-based portal software product Citrix acquired when the company purchased Sequoia Software Corporation earlier this year. XPS enables businesses of all sizes to streamline and automate complicated business operations, and provides a single window through which anyone in the enterprise can interact with partners, vendors, customers and fellow employees in real time, achieving results in seconds instead of days. Built upon an XML server that provides support for massive numbers of users and volumes of data, XPS combines flexibility and significant functionality, easing adoption and deployment.

SharePoint Portal Server is a flexible portal solution that allows companies to easily find, share and publish information. Each standalone server offers enterprise-level search functionality (developed by Microsoft Research) and integrated document management tools. SharePoint Portal Server provides a focal point for finding relevant information stored across multiple data sources, including SharePoint Team Services websites, Exchange data stores, file shares, Notes databases, and Internet sites.

"Citrix is providing its customers with powerful XML-based products and technologies that enable them to easily use any device to find and get connected to information from anywhere," said Gytis Barzdukas, group product manager of the SharePoint Portal Server Business Unit at Microsoft. "SharePoint Portal Server as part of XPS will help customers build a more complete portal solution with a way to organize, find and share information created with Microsoft applications."
