Acquisition to Enhance Citrix's Role in Web-based Application Deployment and Management FORT LAUDERDALE, Fla. - July 12, 1999 - Citrix Systems, Inc. (Nasdaq:CTXS) today announced a merger agreement pursuant to which ViewSoft, Inc. will become a wholly-owned subsidiary of Citrix. ViewSoft is a Utah-based firm specializing in software for multi-tier and Web-based application development and deployment. The transaction is valued at approximately $32 million. Both the Citrix and ViewSoft boards have approved the transaction, and the companies plan to complete the transaction during the third quarter of 1999, subject to customary closing conditions. Citrix will use the proprietary technology to extend the flexibility and cost benefits of server-based computing to Web-enabled and multi-tier applications including applications based on Microsoft's DCOM and DNA component architectures as well as those containing Java and HTML front ends. A portion of the purchase price is expected to be allocated to in-process research and development for which Citrix expects to incur a one-time charge to its operations, amounting to approximately $2 million in the quarter ending September 30, 1999. "Today's emerging Web-based applications often force a choice between application thinness and richness," said Mark B. Templeton, president and chief executive officer of Citrix. "This new software will deliver a rich user experience and a new level of interactivity to Web-based applications with a thin-client footprint." The technology allows customers to add greater interactivity to Web-based applications, similar to the interactivity that users enjoy with Windows-based applications. Citrix will leverage this proprietary technology to build its leadership in the rapidly growing market for deploying and managing Web-based applications, an arena in which the company has pioneered such capabilities as Application Launching and Embedding (ALE). Citrix's ALE technology enables full- function Windows-based applications to be launched from or embedded into HTML pages providing instant online access to any existing application from any Web browser without application rewrites.
