LAS VEGAS--(BUSINESS WIRE)--May 11, 1999--

Citrix Systems, Inc. (Nasdaq:CTXS), the world leader in system software for server-based computing, today announced at Networld + Interop (Booth No. 2402, North Hall) that it has joined forces with 25 leading technology companies to form an international advocacy group dedicated to fostering the development of the fast-emerging Application Service Provider (ASP) segment of the computer industry.

Based in Massachusetts, the Application Service Provider Industry Consortium (ASP Industry Consortium) will sponsor research, foster standards and work to articulate the measurable benefits of the evolving ASP delivery model. In addition to Citrix's role as a founding member of the newly formed ASP Industry Consortium, Traver Gruen-Kennedy, Citrix's director of advanced business development, was elected chairman of the Consortium and will hold a seat on the Consortium's Board of Directors.

"Citrix has been working with ASPs to deliver application services to corporate customers and consumers for more than a year," said Kennedy. "As a catalyst behind the growth of this market, we are extremely excited to see our efforts come to fruition with the formation of the Consortium. Citrix's Independent Computing Architecture(R) and server-based computing model have consistently delivered results in corporate enterprises worldwide. Now, through the ASP model, this same architecture will extend the reach of best-of-breed technology solutions to even the smallest, most resource-constrained companies, serving to level the playing field and competitive landscape."

In a move that demonstrates its commitment to the growing ASP trend, Citrix recently announced the creation of a business unit focused on the Internet to expand the company's current role in the rapidly developing ASP market. The formation of the iBusiness unit is Citrix's response to continued customer demand for anytime, anywhere access to applications. In the coming months, Citrix expects to announce formal programs for ASPs as well as product and technology directions in support of ASP and Internet market demands.
