Citrix ICA Protocol Sparks Development of Pen-Based Computers for Windows Applications; Telxon Joins Growing Family of Citrix ICA Protocol Licensees to Develop Windows-Based Network Computing Devices.

CORAL SPRINGS, Fla.--(BUSINESS WIRE)--May 28, 1996--Citrix Systems, Inc. (NASDAQ: CTXS) today announced it has signed a letter of intent with Telxon Corporation (NASDAQ: TLXN) to embed its ICA distributed Windows protocol in all future versions of Telxon ruggedized pen-based computers. The inclusion of Citrix's(R) ICA(R) thin client software will enable Telxon to develop wireless network devices that are low-cost, light-weight and capable of running existing and future Win16, Win32 and client/server applications in conjunction with Citrix's WinFrame/Enterprise multi-user Windows application server software.

As the first general-purpose presentation services protocol for Windows, ICA is being broadly adopted by industry leading vendors -- including Microsoft Corporation, Wyse Technology, Tektronix, Insignia Solutions, and NCD -- for inclusion in new hardware and software products. The Citrix ICA protocol delivers the benefits of Windows-based, network-centric computing to users of low-cost terminals and information appliances; users of non-Windows platforms, such as DOS, UNIX and Macintosh; users of rapidly emerging small form factor PDA's and other wireless devices; as well as users over the Internet or Intranet.

"We are pleased Telxon has joined our growing family of OEM and strategic partners that recognize the power of ICA technology," said Edward Iacobucci, Citrix chairman and chief technical officer. "The fact Telxon plans to use ICA to develop a Windows environment around wireless network devices is a clear indication of how extensible the protocol is and how easily it can be used to deploy Windows to a broader variety of markets."

A leading global designer and manufacturer of wireless and mobile transaction systems for vertical markets, Telxon sees significant value in delivering the power of the desktop to mobile workers, which is made possible by incorporating Citrix's ICA thin client software in its line of ruggedized pen-based computers. "The strategic relationship established between Citrix and Telxon will provide our customers, who are committed to the Microsoft Windows standard, with an effortless transition to pen-based computing with optimal performance and minimal cost," said David Loadman, senior vice president, global technical operations for Telxon Corporation.

Telxon's family of ruggedized pen-based computers will work in conjunction with Citrix's WinFrame/Enterprise multi-user application server software. Built as an authorized extension to Windows NT Server under license from Microsoft, WinFrame/Enterprise employs a network-centric computing model. Enterprise applications execute on the WinFrame/Enterprise application server, while only the graphical user interface runs on the Telxon wireless client. WinFrame/Enterprise's thin client architecture provides the high-performance and universal application access needed by users, while the multi-user application server design offers I/S professionals the economic benefits of single-point management and control.

Conceptually similar to the UNIX X-Windows protocol, ICA allows an application's user interface to execute with minimal resource consumption on client devices, while the application logic executes on ICA-based servers. The Citrix ICA protocol turns any PC into a thin Windows-base network computer and also empowers new-generation thin client devices to be developed with standard Windows functionality. With ICA client software, users can access Win16 and Win32 applications running on a remote ICA-based server by launching them from web-based HTML pages or from Windows desktops over dial-up, LAN, WAN or Internet connections.

Citrix Systems, Inc. develops, markets and supports multi-user application server software under license and strategic agreement with Microsoft. The company's flagship product line, WinFrame(TM), enables the high-performance, enterprise-wide deployment of Windows applications without regard to location or type of client hardware platform. Founded in 1989, Citrix is based in Coral Springs, Fla.

Investors are cautioned that all forward looking statements involve risks and uncertainties, including, without limitation, risks associated with the Company's reliance upon its strategic relationships with Microsoft and other strategic partners, dependence upon broad-based acceptance of the Company's ICA protocol, management of growth, and dependence on proprietary technology, as well as risks of downturns in economic conditions generally, and in the software industry specifically, risks associated with competition and competitive pricing pressures, and other risks detailed in the Company's filings with the Securities and Exchange Commission. -0-
