New Products Deliver on Citrix Vision of Application Access by

Users Anywhere, on Any Device, Over Any Connection

Citrix Systems, Inc. (Nasdaq:CTXS) today announced the availability of its newest members of the family of Citrix(R) MetaFrame(TM) 1.1 for UNIX(R) Operating Systems application server software products: Citrix MetaFrame 1.1 for the AIX(R) Operating System, Citrix MetaFrame 1.1 for the HP-UX(R) Operating System and Citrix MetaFrame 1.1 for the Solaris(TM) Operating Environment. These new products are being demonstrated this week at Citrix iForum(TM) 2000 in Orlando, Florida.

The Citrix MetaFrame 1.1 for UNIX Operating Systems product family extends the reach of business-critical UNIX and Java(TM) applications across an enterprise, or from an Application Service Provider (ASP), to users anywhere, regardless of location, device or connection. The unique way in which MetaFrame 1.1 for UNIX can deliver UNIX applications to any Citrix Independent Computing Architecture (ICA(R)) client, over any connection makes it an excellent alternative to using PC X Servers to deploy X.11 applications in the enterprise. This expansion of the MetaFrame product line is further evidence of Citrix's strategy to deliver high-speed access to any application, over any device, across any connection. These new MetaFrame products are available immediately through selected members of the Citrix Solutions Network(TM), a comprehensive channel of distributors, resellers, system integrators, and consultants worldwide. Suggested retail pricing for each product is $5,995 for a 15-concurrent user license and a one-year enrollment in Citrix's Subscription Advantage program, which includes automatic delivery of enhancements, updates and maintenance releases.

"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."

"Citrix's award-winning MetaFrame software technology is a natural choice for customers who want to deploy reliable UNIX server-based computing solutions," said Gary Thomassen, director of product management for Citrix. "It provides

added value to enterprise customers and ASPs by enabling access to applications and information regardless of platform. In conjunction with the Citrix NFuse application portal software, users can now have seamless access to both Windows and UNIX applications via a single Web portal interface."

"We are pleased that Citrix is providing its MetaFrame application server software as an enhanced capability to the HP platforms," said Ram Appalaraju, director of e-services operating environment, Hewlett-Packard Company. "Designed with the open architectures of PA-RISC, the HP-UX Operating Environment provides a powerful solution to help reduce the total cost of ownership of a customer's IT investments."

"We are pleased to be working with Citrix to provide MetaFrame applications server software as an enhanced capability for our AIX customers," said Kristian Thyregod, vice president, worldwide marketing execution, IBM Corporation. "With Citrix MetaFrame for the AIX Operating System, IBM's AIX Operating System customers can use a personalized Web browser to deploy their applications within a multi-platform environment. The capabilities of IBM's AIX Operating System, combined with the advantages offered by Citrix MetaFrame for the AIX Operating System, provides a powerful and efficient solution, while reducing the total cost of ownership for a customer's IT investments."

"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, provide a powerful and efficient solution."

Key Features

Extends the Reach of UNIX and Java Applications

Using Citrix ICA technology, Citrix MetaFrame for UNIX Operating Systems enables the deployment of UNIX systems, X.11, text and Java applications across an enterprise, or from an ASP, to branch office and mobile workers who could not have accessed them previously due to bandwidth limitations or device capabilities.

--  Support for Multiple Vendor Platforms - Citrix MetaFrame 1.1 for
    UNIX Operating Systems supports the following platforms: HP's
    HP-UX 11 Operating Environment; IBM's AIX Version 4.3.3 Operating
    System on the RS/6000; and Sun's Solaris 8 Operating Environment
    on both SPARC and x86, in addition to Solaris 2.6 and 7 on SPARC,
    and Solaris 7 Operating Environment on x86.

--  Provides Broader and more Cost-Effective Solution than PC X
    Servers - Citrix MetaFrame for UNIX Operating Systems eliminates
    the need for PC X Servers in the majority of user environments. In
    addition, MetaFrame for UNIX provides additional functionality and
    flexibility to allow users to extend business-critical UNIX
    applications further into their environments. MetaFrame for UNIX
    is not limited to the PC as a client device; it supports an
    extensive list of client devices, thereby providing a much broader
    and more cost-effective solution than PC X Servers. Also,
    MetaFrame is a "thin" solution that requires a fraction of the
    bandwidth that is required to use PC X Servers. This enables
    wireless, dial-up and other mobile scenarios to be possible that
    aren't practical in a PC X Server environment.

--  Centralized Application Management and Deployment - The product
    offers enterprise management and deployment tools to allow IT
    departments and ASPs to scale, deploy, manage and support
    applications from a single location.

--  Web Access via NFuse(TM)- Citrix MetaFrame for UNIX Operating
    Systems enables UNIX systems and Java applications to be deployed
    directly from a Web page. Companies or ASPs can rapidly deploy
    existing applications through a Web browser without rewriting any
    code, using Citrix NFuse application portal software.

--  Client Devices - MetaFrame provides UNIX application access from
    all types of devices, ranging from PCs and notebook computers to
    the latest handheld devices.

Incorporates Standard MetaFrame Features

MetaFrame for UNIX Operating Systems contains the same key features that every one of the FORTUNE 100 companies currently enjoys with MetaFrame for Windows.

-0-
--  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 - Citrix Load Balancing Services is an optional
    package that allows multiple servers to be grouped into a unified
    "server farm" to meet the needs of a growing user base. This
    provides greater manageability and scalability, enabling
    administrators to reduce the computing costs and resources needed
    to support users and systems.

--  Session Shadowing - Administrators and help-desk employees can
    monitor, manage and even take control of a user's session at a
    remote location by using Citrix MetaFrame for UNIX Operating
    Systems' shadowing capability. This feature makes remote support,
    diagnosis and training easy for UNIX systems and Java
    applications.

--  SpeedScreen(TM) 2 Technology - Citrix's ICA protocol, with
    SpeedScreen 2, improves network efficiency, accelerating the
    performance of congested corporate networks and helping to reduce
    the communication costs of wide-area networks. SpeedScreen 2 also
    reduces bandwidth consumption, boosting the productivity of remote
    and mobile users.

--  Seamless Desktop Integration - MetaFrame offers an enhanced user
    experience by providing complete access to local system resources,
    including clipboard and local printers. Although applications run
    remotely from the server, they look, feel and perform as though
    they are running locally. By providing this level of comfort for
    users, MetaFrame eliminates the need for training and increases
    user productivity.

--  Disconnect/Reconnect - 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.

--  Integrates with Security Products - Citrix MetaFrame for UNIX
    Operating Systems can be used with a range of security products to
    encrypt and secure ICA connections on any network, including the
    Internet (e.g., Citrix Extranet(TM)). Administrators can configure
    servers to authenticate against a wide range of user accounts
    systems, including NIS and NIS+.

Universal Application Access

-0-
--  NFuse - NFuse allows enterprise organizations and ASPs to publish
    unmodified interactive applications to any standard Web browser.
    NFuse enables users working in a mixed server environment to
    access both UNIX and Windows applications from a single Web
    portal. Citrix MetaFrame for UNIX Operating Systems, combined with
    Citrix NFuse, offers fully dynamic generation of user-personalized
    Web pages.

--  Interoperability with MetaFrame for Windows - To meet the needs of
    current and future users, Citrix MetaFrame for UNIX Operating
    Systems is interoperable with MetaFrame for Windows. The MetaFrame
    product line has been designed to enable coexistence of both
    products in a single server farm.

--  Any Client - The MetaFrame family extends applications to
    virtually any client device, including 286, 386, 486, and Pentium
    or Celeron PCs, Windows-based terminals, network computers,
    wireless devices, and information appliances. All types of Windows
    clients are supported, including Windows 3.X, Windows for
    Workgroups, Windows 95, Windows NT(R) Workstation and Windows CE.
    Additionally, non-Windows clients are supported, which include
    DOS, UNIX, Linux(R), OS/2 Warp(R), Mac(R) OS, Java, as well as the
    Symbian(TM) EPOC(TM) platform.

--  International Support - With support for many international
    keyboards, users can utilize their native keyboard and type text
    strings in their own language, providing greater familiarity and
    easier adoption.

--  Network Connections - MetaFrame connects users to the network
    through standard telephone lines, WAN links (T1, T3, 56Kb, X.25),
    broadband connections (ISDN, Frame Relay, ATM), wireless
    connections, corporate intranets and the Internet.
