Citrix XPS Portal Software to Leverage SharePoint

Citrix and SiteScape Form Alliance to Give XPS™ Portal Customers Enhanced Collaboration Capabilities

FORT LAUDERDALE, Fla.- July 25, 2001 - Citrix Systems, Inc. (Nasdaq:CTXS), a global leader in application serving and portal software and services, today announced an alliance with SiteScape, Inc., a leading provider of Web-based collaboration software and services. The agreement benefits Citrix customers by giving them the ability to integrate SiteScape Enterprise Forum 6.0 collaboration software or WebWorkZone hosted service as an optional, plug-in component of Citrix® XPS™, the company's XML-pure portal software. In addition to the product integration, SiteScape has joined the Citrix Business Alliance™ (CBA) Internet Solutions Program, expanding joint marketing and sales opportunities for both companies.

"Citrix customers are turning to Citrix XPS to help them enhance business processes and communication with users across departments, business units, and value chains," said Barry Davis, vice president, Business Development, for Citrix. "By partnering with SiteScape we're adding value to XPS, offering our customers a powerful and customizable collaboration platform that can dramatically improve intra- and cross-enterprise communication and work processes."

Citrix XPS portal software gives users a single, personalized and secure point of command and control over 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. SiteScape Forum 6.0, which allows users to host online discussions; share documents; chat; create and participate in workflows; schedule meetings using shared calendars; and send quick messages, is a powerful extension of XPS capabilities. SiteScape functionality will be accessed through an XPS Content Delivery Agent (CDA), an individual, easy-to-use Web-based application that snaps directly into the users' homepage.

"We've seen that the combination of collaboration and workflow capabilities within the portal is becoming increasingly important for the enterprise," said Richard M. Tahan, Jr., SiteScape's vice president of worldwide channel marketing. "SiteScape's collaboration software allows XPS customers to make faster, better decisions by allowing them to discuss and get input on the various information sources that XPS aggregates. In addition, Forum captures the decision-making process in perpetuity, forming a knowledge base of tacit information."
Tahan continued, "We're excited about our partnership with Citrix and share their enthusiasm for making our alliance a success."
