Citrix Thin-Client/Server Computing Model Opens Windows to New Range of Computing Devices.

FORT LAUDERDALE, Fla.--(BUSINESS WIRE)--May 5, 1998--

Five Companies License Citrix's Independent

Computing Architecture to Develop Set-Top Boxes,

NCs and Ultra-Thin Access Devices

With the goal of delivering Windows-based applications to the widest range of users, Citrix Systems, Inc. (Nasdaq:CTXS) today announced definitive licensing agreements with five hardware and software manufacturers -- including Aranex, Boca Research, Inc., Caldera, Inc., MTX, Inc., and Netier Technologies, Inc. -- for its Independent Computing Architecture. ICA(R), an emerging industry standard for thin-client/server computing, enables efficient deployment of Windows(R)-based applications throughout the enterprise, regardless of available bandwidth, type of client hardware or operating platform.

Under the licensing agreements, the companies will incorporate Citrix's ICA technology into a wide variety of existing and future products, including Internet access devices (Boca Research), ultra-thin access devices (Netier Technologies, Inc.), network computers (Aranex, MTX) and embedded operating systems (Caldera). These devices, which work in conjunction with Citrix WinFrame(R) and upcoming MetaFrame(tm) thin-client/server software, will reduce the complexity in accessing business critical applications, while reducing total cost of application ownership.

"Citrix has a singular vision that drives everything we do -- to deliver business-critical applications to users on the broadest choice of devices," said Edward Iacobucci, chairman and chief technology officer for Citrix. "The growing popularity of thin-client/server computing has resulted in an increasing number of innovative ICA-based devices that reduce the complexities of computing. These devices enable organizations to easily access and manage their business-critical applications from a central location. Providing users with a broadened choice of computing devices to access critical applications is a major step toward making computing ubiquitous."

ICA has been licensed for incorporation into the following OEM products:

-- Aranex - The Internet Client Station Series 2000, which will

launch this month, is a cost-effective thin client for business

users that offers access to a broad range of enterprise

applications, including legacy solutions, and to corporate

Internet/intranet servers. With the Internet Client Station,

organizations are able to implement Internet-based computing at

significant cost savings. www.aranex.com

-- Boca Research, Inc. - With an estimated street price of under

$400, the BocaVision set-top Internet access device broadens user

access to Windows-based applications and data across the Web via

a TV or VGA monitor and an analog telephone line. Through Citrix

ICA, the BocaVision set-top device provides users in remote

locations with access to business-critical applications residing

centrally on a Citrix server. www.bocaresearch.com

-- Caldera, Inc. - DR-WebSpyder, the company's compact,

high-performance, graphical Web browser, extends the proven power

of the multi-tasking, ROMable embedded DR-DOS operating system.

DR-WebSpyder is a new graphical interface and set of Web

protocols for powering interactive information kiosks, network

computers, Internet-enabled set-top boxes, and hand-held devices

with displays. Embedded OEMs that utilize the combination of

Citrix ICA, DR-WebSpyder and DR-DOS can reduce time-to-market by

leveraging the large number of experienced developers and proven

development tools for DOS. Incorporation of Citrix ICA enables

the operating system to deliver cost benefits of server-based

application manageability and access to Windows applications

demanded by corporate adopters of thin devices. www.caldera.com

-- MTX, Inc. - MTX 1683 Network Computing Terminal (NCT) is a

desktop device that offers the advantages of 3270 host support,

Internet/intranet access, e-mail, centralized application

management and low acquisition cost. With a June availability of

Citrix ICA support, it is designed for organizations migrating

from fixed-function devices to intelligent desktop computing, and

those seeking to reduce TCO. www.mtx.com

-- Netier Technologies, Inc. - The NetXpress SL and XL models are

access devices that enable users to scale their desktops from

ultra-thin, diskless devices to enhanced access units. The

integration of ICA into NetXpress provides users with the same

computing power of a Windows-based system for significantly lower

cost, while enabling improved management of network resources.

About Citrix ICA

With over one million concurrent user licenses since its introduction in 1995, the Citrix Independent Computing Architecture (ICA) is an emerging industry standard for thin-client/server computing. Citrix's Independent Computing Architecture includes a server software component, a network protocol component and a client software component. On the server, ICA separates application logic from the user interface and executes 100% of the application on the server. The ICA network protocol transports keystrokes, mouse clicks and screen updates over standard protocols to the client, consuming less than 20 kilobits-per-second of network bandwidth. On the client, users see and work only with the application's interface.

Citrix's Independent Computing Architecture is being broadly adopted by industry leading vendors -- including Microsoft, HP, IBM, Sun Microsystems, Sharp, Wyse, Boundless, NCD, Cruise and others -- for inclusion in new and future hardware and software products that extend the reach of enterprise applications without regard to client hardware, operating platform, network connection or available bandwidth. Citrix's open licensing strategy for ICA enables OEMs to deliver the benefits of thin-client/server computing to users of low-cost Windows-based terminals, network computers, wireless devices and a new range of low-cost, lightweight information appliances.
