CANNES, France--(BUSINESS WIRE)--Feb. 20, 2002

Citrix(R) ICA(R) Enables Delivery of Windows, UNIX Applications to

ViewPad 1000 Tablet PC and ViewPad 100 SuperPDA

Citrix Systems Inc. (Nasdaq:CTXS), a global leader in virtual workplace software and services, today announced that it has signed a licensing agreement with ViewSonic(R) Corporation, a worldwide Visual Technologies(TM) leader. ViewSonic has incorporated Citrix(R) Independent Computing Architecture (ICA(R)) technology in the ViewSonic ViewPad 100 SuperPDA and the ViewSonic ViewPad 1000 Tablet PC.

With Citrix ICA, enterprise users of the ViewPad family can now access applications running on Citrix MetaFrame(R) servers over wired and wireless connections, including over 802.11b wireless LANs and wireless wide area networks. Citrix application serving technology centralizes all application processing on the server and exchanges only keystrokes, mouse clicks and screen updates across the network with a Citrix ICA-enabled device.

The ViewPad 100 and the ViewPad 1000 are designed for users in the office, on the road or at home. The ViewPad 100 is a generation beyond traditional, limited PDA and e-mail pager devices and supports personal information management, and wireless access to the Web and to server-based enterprise applications. The ViewPad 1000 offers full PC functionality in a tablet form factor, evolving from the traditional notebook, while adding stylus support and integrated digital photography.

"Enterprises are increasingly being challenged to extend the reach of their applications to mobile employees," said Aaron Fright, European product marketing manager, ViewSonic Europe. "Citrix's ICA technology offers our enterprise customers the ability to connect to any application or service deployed through Citrix's virtual workplace solutions."

"As companies expand geographically and employers strive to maintain the productivity of remote workers, the virtual office empowers users to work effectively anywhere by giving them a familiar workplace on a wide array of wireless devices," said Linda Erton, senior director, Wireless, for Citrix. "By incorporating Citrix ICA technology into its ViewPad devices, ViewSonic is enabling enterprises to rapidly extend increasingly sophisticated applications and services to their mobile users."

About Citrix ICA

Citrix Independent Computing Architecture (ICA) is an emerging industry standard for server-based computing. Citrix ICA technology includes a server software component, a network protocol component, and a client software component. ICA separates application logic, which executes 100 percent on the server, from the user interface. This allows efficient, server-based application installation, management, deployment and support. The ICA network protocol transports keystrokes, mouse clicks and screen updates over standard protocols to the client, typically consuming only 10-15 kilobits-per-second of network bandwidth. ICA client software, which supports virtually any device or platform, lets users view and work with the interface as if the application were running locally.
