Network Terminal, Wireless Manufacturers Embrace Citrix's ICA Protocol for Windows Application Support.

CORAL SPRINGS, Fla.--(BUSINESS WIRE)-- October 28, 1996 - Citrix Systems, Inc. (NASDAQ:CTXS) today announced it has signed non-binding letters of intent with VXL Instruments Limited and HDS Network Systems (NASDAQ:HDSX) for the ICAR distributed WindowsR protocol. The ICA protocol will enable VXL and HDS to develop network terminals capable of running standard Windows applications in conjunction with Citrix's WinFrame multi-user application server software. Citrix today also announced it has entered into a definitive licensing agreement with Telxon Corporation to embed ICA support into the Telxon line of mobile wireless pen-based computers.

"The addition of VXL, HDS and Telxon to our family of distinguished ICA licensees furthers our strategy for making business-critical Windows applications accessible to the broadest range of users, regardless of user location, type of client device, operating platform or available bandwidth," said Edward Iacobucci, Citrix chairman and chief technical officer. "The ICA protocol is rapidly becoming the industry standard for delivering 32-bit Windows applications to a variety of new markets, such as network terminals and wireless devices, that were previously unable to benefit from robust Windows applications."

VXL Instruments Limited

VXL Instruments, a manufacturer of ASCII and ANSI terminals, will incorporate the ICA protocol in future versions of its network terminal product line, which will be available in early 1997. Citrix's ICA technology will enable VXL Instruments to develop a broad range of fixed-function terminals, designed to deliver 32-bit Windows applications to specific markets, such as point-of-sale and banking, that have been traditionally tied to non-graphical ASCII terminals.

"VXL is committed to developing a range of ICA-based thin clients, beginning with WinLinx, a network terminal for Windows NT," said Jay Savoor, director of marketing for VXL Instruments Ltd. "Together, the VXL line of ICA-based terminals and WinFrame application server software are a natural fit for organizations migrating corporate applications from the host system/ASCII terminal model to Windows NT Server. This network-centric solution preserves I/S control over cost-effective, manageable application deployment, while empowering users with 32-bit Windows applications."

HDS Network Systems

HDS signed a letter of intent with Citrix to embed the ICA protocol in its line of @workStation network computers and its netOS. The inclusion of the ICA protocol will enable @workStation users to run 16- and 32-bit Windows applications in conjunction with WinFrame multi-user application server software.

"We consider Citrix's ICA protocol and WinFrame application server software important to our customers success," said Mike Kantrowitz, executive vice president of HDS. "By adding ICA protocol support to our @workStation network computers, we offer I/S organizations a cost-effective, easy solution for deploying and managing business-critical Windows applications, while providing users the freedom and power to take advantage of these applications from anywhere."

Telxon Corporation

Under the definitive licensing agreement with Citrix, Telxon has rights to embed the ICA protocol in its line of mobile wireless pen-based computers. The inclusion of the ICA protocol will enable Telxon to develop wireless network devices that are low-cost, light-weight and capable of running 32-bit Windows and client/server applications in conjunction with WinFrame multi-user application server software.

"The strategic relationship established between Citrix and Telxon will provide customers with optimal performance and maximum cost savings generated by the power of a full Windows desktop in a compact, ruggedized pen-based computer," said David Loadman, senior vice president, global technical operations for Telxon Corporation.

About ICA

Citrix's ICA protocol is being broadly adopted by industry leading vendors including Microsoft Corporation, Sun Microsystems, Wyse Technology, Boundless Technologies (formerly known as SunRiver Data Systems), Tektronix, Insignia Solutions, and NCD for inclusion in new and future hardware and software products that extend the reach of Windows applications into new markets where such applications could not previously run, due to limited processing power, RAM, bandwidth or other limitations.

ICA is a general-purpose presentation services protocol for Microsoft Windows, which allows an application's user interface to execute with minimal resource consumption on a client device, while the application logic executes on ICA-based servers, such as the Citrix WinFrame family of multi-user application servers.

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, 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.
