FORT LAUDERDALE, Fla.--(BUSINESS WIRE)--May 16, 2002

Citrix Systems, Inc. (Nasdaq:CTXS), a global leader in virtual workplace software and services, announced today that it has reached an agreement to formalize continued access to Microsoft(R) Windows(R) Server code.

In 1997, Microsoft and Citrix entered into an agreement whereby Citrix developed technology for Microsoft that is now part of the Windows server operating systems. Bob Kruger, senior vice president, product development and chief technology officer for Citrix, said today's agreement is a logical next step in Citrix's relationship with Microsoft.

"This deal does not extend the 1997 agreement," Kruger said. "Rather it ensures that Citrix will continue to have access to new Windows releases in the future. It also demonstrates Microsoft's recognition of the value Citrix solutions add to the Microsoft platforms."

Citrix will have access to current and future Microsoft server operating systems including access to Terminal Server interfaces for three years. Citrix(R) MetaFrame(R) application serving software works with and adds value to the Windows server operating systems.

The program agreement does not include financial payments to or from either party.
