FOR IMMEDIATE RELEASE



   CITRIX AND FTP SOFTWARE JOIN FORCES TO DISTRIBUTE STANDARD
               WINDOWS PROGRAMS OVER THE INTERNET
      WinView Application Servers Form Backbone for New Era
         of Interactive Windows-Based Internet Services
                                
NETWORLD + INTEROP, ATLANTA, GA -- SEPTEMBER 12, 1994 -- CitrixTM
Systems,  Inc.  and  FTP  Software,  Inc.  (NASDAQ:  FTPS)  today
announced  a  broad  initiative to deliver a  new  generation  of
Windows  capabilities for Internet service publishers and  users.
Citrix  has  incorporated technology from FTP Software  into  its
WinViewTM  for Networks application server software, forming  the
infrastructure  for  interactive  Windows  programs  across   the
Internet.  This  is  the  first solution available  that  enables
Internet  publishers  to deliver interactive Windows  information
services,   using   off-the-shelf   Windows   applications    and
development  tools.  Citrix and FTP Software  will  cooperate  in
future   projects  to  deliver  additional  interactive   Windows
capabilities   that   integrate  existing  Internet   tools   and
architectures.

   Citrix  also announced today WinView for Networks version  2.3
and  TCP/IP for WinView version 1.0. WinView for Networks version
2.3 is a major upgrade, providing base functionality for Internet
access.  TCP/IP for WinView version 1.0 is add-on  software  that
supplies full TCP/IP support for WinView servers. Citrix licensed
portions  of FTP Software's TCP/IP stack technology for inclusion
in  the new TCP/IP for WinView product. Please see separate press
release for more details on WinView for Networks version 2.3  and
TCP/IP for WinView.

   "Citrix application server technology opens the Internet to an
exciting  new  level  of service opportunities,  giving  it  even
broader  appeal  for  more  people,"  said  David  Fowler,   vice
president of marketing and sales for FTP Software, Inc.  "Today's
announcement  will  bring  the Information  Superhighway  a  step
closer   through   the  accelerated  delivery  of   new   Windows
information  services. Until now, interactive Windows information
services  could not be published over the Internet. Citrix  makes
it  possible  to  rapidly develop and deploy interactive  Windows
services  to Internet users, so anyone familiar with Windows  can
now publish Internet services."

   "As a respected leader in the TCP/IP world, FTP Software is  a
perfect  partner for Citrix," said Edward Iacobucci, founder  and
chairman  of  Citrix  Systems,  Inc.  "With  these  exciting  new
capabilities, publishing an information service on  the  Internet
is  as simple as writing a Windows application. Any organization,
large  or  small, can use WinView for Networks to easily disperse
information to a growing base of worldwide users."

   Central  to  today's  announcement is the  adaptation  of  the
Citrix  distributed Windows protocol, called Intelligent  Console
Architecture (ICATM), to the TCP/IP environment. Citrix developed
its  ICA protocol to provide fast remote Windows services for its
line   of   application  server  software.   ICA   runs   Windows
applications locally on WinView application servers, sending only
user   interface   objects  and  events  to  client   PCs.   This
architecture allows off-the-shelf Windows applications (including
Windows  standard and enhanced mode programs) to perform at  very
high speed over low bandwidth connections. In use by thousands of
Citrix servers worldwide, ICA is a mature and efficient protocol.

   TCP/IP  is  the industry-standard communications protocol  for
heterogeneous  distributed  computing  networks.  FTP  Software's
flagship  product,  PC/TCP  network  software,  is  one  of   the
industry's  leading software for running TCP/IP on  Windows,  DOS
and  OS/2 PCs. Citrix created an interface between the TCP/IP and
ICA protocols, allowing ICA to run over TCP/IP.

   The  two  companies will investigate ways to further integrate
the distributed Windows protocol with existing Internet directory
architectures  and user interface tools, such as the  World  Wide
Web (WWW) and Mosaic.

   By  incorporating  TCP/IP  technology,  WinView  for  Networks
application  server software greatly expands the availability  of
information services on the Internet; since anyone familiar  with
Windows  can publish an information service. Until now,  Internet
publishers had to write programs specifically for the Internet or
World  Wide  Web,  using Unix as the core  operating  system  and
following  stringent rules. By putting a WinView  server  on  the
Internet,  service  publishers can develop  interactive  Windows-
based  services,  using  off-the-shelf Windows  applications  and
development tools. This eliminates the need to have expertise  in
Unix.

   WinView for Networks also facilitates end user access  to  new
information  services  on the Internet.  Many  service  providers
offer  end  users  simple (login) access to the Internet  through
Unix  login accounts. Under this approach, end users do not  have
access to the latest Windows-based Internet tools and must  learn
a   complex  text-based  Unix  environment.  Using  WinView   for
Networks,  Internet  providers can offer a  simple  Windows-based
login  environment, which can, in turn, support  modern  Internet
applications.

   For example, a WinView server, running a Mosaic front-end, can
serve as an Internet gateway, providing access to the World  Wide
Web.  Virtually any user with a PC can now browse the World  Wide
Web  -- without the need to run Windows or Mosaic locally.  Users
only need a modem and the WinView client program, remote link, to
gain  an  IP connection to the Internet to access the World  Wide
Web.

   With  WinView,  users gain access to a new era of  interactive
Windows-based  services  --  all  sharing  a  standard,  familiar
interface. WinView gives users high-speed access to sophisticated
Windows  information programs, regardless of their CPU  power  or
whether  they are running Windows locally. WinView allows low-end
hardware, even 286 PCs not capable of running Windows, to  access
Windows  applications with excellent performance. The  processing
power required to run the small WinView client program (640KB RAM
on a 286 system) is much less than that needed to run Windows 3.1
natively.  All  application  processing  occurs  on  the  WinView
server;  only  the  user interface results are displayed  at  the
workstation. WinView includes a distribution license for  Windows
3.1,  so users without Windows can access the WinView server  and
run Windows-based information services on the Internet.

   WinView  acts  as a secure firewall against Internet  security
threats.  WinView includes advanced, multi-level system  security
to  prevent  users from interfering with each other;  to  prevent
users  from  accessing unauthorized information; and  to  prevent
users  from  damaging  system operation.  Access  to  WinView  is
controlled  by  password security, while access to resources  and
facilities within the system is controlled by security attributes
and  classifications.  WinView includes  remote  access  security
features, such as dial-back, to verify remote user identity;  and
disconnect    recovery,   to   maintain   and    password-protect
disconnected  remote sessions. Logon sequence encryption  ensures
all data going across the wire from the client to the host during
the  login  process is encrypted, providing secure transportation
of  user  names  and passwords over phone lines  and  across  the
Internet.
