Business Editors/High-Tech Writers

FORT LAUDERDALE, Fla.--(BUSINESS WIRE)--Aug. 1, 2000

Features include Support for Sun Microsystem's Solaris 8 and

Enhanced NFuse(TM) Integration

Citrix Systems, Inc. (Nasdaq:CTXS) today announced a new version of its application server software - Citrix(R) MetaFrame(TM) 1.1 for UNIX(R) Operating Systems. Version 1.1 will first be available in August, beginning with MetaFrame 1.1 for the Solaris(TM) Operating Environment, which provides added value for customers of Sun Microsystems, Inc. (Nasdaq:SUNW). The features of version 1.1 will also be offered in new Citrix UNIX products for the IBM and HP operating systems later this year. Citrix has extended its products beyond MetaFrame for Windows to support the three market-leading UNIX Operating Systems. This is a key element in Citrix's strategy to deliver high-speed access to any application, over any device, across any connection. New features in version 1.1 include: support for Sun's Solaris 8, enhanced international support, improved access to applications via NFuse(TM) Web application portal, graphics copy and paste, and broader user authentication.

Citrix MetaFrame for UNIX Operating Systems extends the reach of business-critical UNIX and Sun's Java(TM) applications across an enterprise, or from an Application Service Provider (ASP), to users anywhere, regardless of location, device or connection. Empowered by Citrix's Independent Computing Architecture (ICA(R)) technology, Citrix MetaFrame for UNIX Operating Systems shifts 100 percent of application processing to the server, resulting in very low bandwidth requirements, thus eliminating device restrictions typically encountered with emulation software. Citrix MetaFrame for UNIX Operating Systems is being utilized worldwide in companies including Deutsche Bank, Madison River Communications and Motorola.

"We are expanding the Citrix MetaFrame for UNIX Operating Systems family in support of our strategy to extend our product line, as well as to increase the value we bring to enterprise customers and ASPs by enabling access to applications and information regardless of platform," said Keith Turnbull, vice president of product development for Citrix. "Furthermore, with Citrix NFuse, both Windows(R) and UNIX applications can be accessed via a single Web portal interface."

"With Citrix MetaFrame 1.1 for the Solaris Operating Environment, Sun's Solaris 8 Operating Environment customers can use one personalized Web browser to deploy their applications within a multi-platform environment," said Andy Ingram, vice president of Sun Microsystems. "The processing power and service level of the Solaris Operating Environment, coupled with the increased administration, performance, and simplicity offered by Citrix MetaFrame 1.1 for UNIX Operating Systems, provides a powerful and efficient solution."

"The software revenues in the virtual user interface (VUI) serverware market grew over 117% between 1998 and 1999," said Dan Kusnetzky, vice president for system software research for IDC. "Citrix was the leading supplier of software in this market. IDC believes that the interest in server-centric computing, which is dependent on VUI software, will increase rapidly over the next few years. This approach allows users to access UNIX, Windows, and mainframe applications without having to be burdened with issues like system management, network management, application installation, etc."

MetaFrame for the Solaris Operating Environment Customers

"For our IT department, MetaFrame for the Solaris Operating Environment has provided fast, predictable application deployment, enabling high-performance accessibility from almost any device," said Anthony Hall, Foreign Exchange trading systems consultant at Deutsche Bank. "The MetaFrame application server software solution has provided our company with greater manageability of our computing resources, along with reduced overhead and support costs. With version 1.1, support for international keyboards will be an advantage for us."

"Network engineers and administrators in our various locations were experiencing very slow performance from UNIX-based network management applications delivered using the X.11 protocol," said Michael McCollough, senior manager, Network Services for Madison River Communications. "Based on our positive experience with MetaFrame for Windows 2000, we expected great performance from Citrix's new Solaris product, and we got it. The Citrix ICA protocol is working tremendously. Our MetaFrame for the Solaris Operating Environment servers deliver applications in real time, compared with screen delays of up to 10 seconds with X.11. Also, we can now deliver UNIX applications to help desk staff on Windows-based terminals, giving them access for the first time."

"MetaFrame for the Solaris Operating Environment has been most impressive. Our engineers working with PCs have achieved a fast, simple way of accessing heavy-duty UNIX engineering tools," said Matt Ferris, manager, Wireless Subscriber Systems Group, Motorola Semiconductor Products Sector. "Previously, our remote telecommuters experienced performance challenges running X-Windows applications, even across high-speed lines. The low bandwidth requirements of MetaFrame have vastly improved performance and users are able to reconnect to dropped sessions easily without losing any unsaved information."

Key Features of MetaFrame 1.1 for UNIX Operating Systems

Flexible Application Access

-- Application Publishing - These features simplify and accelerate the initial
deployment and subsequent updates of applications across the enterprise.
Application Publishing utilities make it easy for administrators to deploy
applications across multiple servers from a single point.

-- Load Balancing Services - Load Balancing is an optional package that allows
multiple servers to be grouped into a unified "server farm." This provides
greater manageability and servers to be grouped into a unified "server farm."
This provides greater manageability and scalability, enabling administrators to
reduce the computing costs and resources needed to support users and systems.

-- Disconnect/Reconnect - As with the previous version, users can

disconnect from applications or desktop sessions, leaving them

running on the server, then reconnect again from another device or

location. This allows users to move between devices or locations

while keeping their applications running.

Seamless Systems Integration

-- Seamless Desktop Integration - With Citrix MetaFrame 1.1 for UNIX

Operating Systems, users have complete access to local system

resources, including clipboard and local printers. With version

1.1, users can now quickly and easily copy and paste graphics, as

well as text, between local applications and remote applications

deployed using ICA.
