IBM and Bristol Technology to Enable Porting of Windows NT Applications to
OS/390

FISHKILL, New York, May 28... IBM and Bristol Technology today announced a
relationship that will result in the availability of Bristol's Wind/U
development environment on IBM's System/390 enterprise computing
platform.

This relationship will enable C and C++ programs written to the Windows NT
APIs (application programming interfaces) to be ported to System/390's
strategic operating system - OS/390. Now, for the first time, customers
and independent solution developers will be able to leverage OS/390's
unique scalable and robust strengths for their Windows NT applications.

This relationship is the latest demonstration of IBM's commitment to
provide open, client/server application capabilities on S/390. "With more
and more companies using the S/390 as an enterprise and network server to
run their business, OS/390 must be able to support widely accepted
application interfaces," said Charles Lickel, vice president, S/390
Software Development.

"We first demonstrated our commitment to openness and interoperability by
providing UNIX interfaces on OS/390," continued Lickel. "In February,
OS/390 was X/Open XPG4 Base Branded. We will apply for X/Open UNIX
Branding later this year. Supporting Windows NT programming interfaces on
OS/390 is another logical step."

Keith Blackwell, president of Bristol Technology, said, "We are excited to
be joining IBM in this effort. Our Wind/U technology is a proven winner in
providing a common development environment for Windows and UNIX platforms.
Adding OS/390 to the list of systems we support allows our mutual
customers and ISVs to further leverage their enterprise development
investments."

Bristol Technology's Wind/U enables developers of Windows NT applications
to port their applications to UNIX environments, including OS/390.
Developers can recompile and link their application source code with the
Wind/U Library using IBM's development tools on OS/390 to generate a
native UNIX version of their application. The Wind/U-ported applications
have the same functionality as the original Windows NT programs. These
applications can be further enhanced by exploiting OS/390 interfaces and
middleware.

Windows NT programming interface support on OS/390 will also give IBM
customers who have Windows NT as part of their distributed architecture,
greater flexibility to deploy their applications on the appropriate
platform for their computing needs. For those applications that must scale
with availability and execute in a secure environment, S/390 is an ideal
platform choice.

In addition, customers whose Windows NT programs access S/390 transactions
and data will now be able to house these applications and data on the same
server. Associated benefits include improved application availability and
reduced network overhead and complexity.

"We are a major S/390 shop, but we are also committed to the Windows NT
application interfaces as part of our distributed application
architecture," said Ashleigh Tanner, IT technical architect, National
Westminster Bank (NatWest). "We need the flexibility to be able to develop
our applications on the optimal platform. Being able to run our Windows
NT-based server applications locally on S/390 in close proximity to our
corporate data and with the characteristics we have come to expect of
S/390 has great appeal to us."

Bristol Technology is a licensee of Microsoft's Windows Interface Source
Environment program. This licensing agreement provides Bristol with source
code for Windows 3.1, Windows 95, and Windows NT on an ongoing basis. This
ensures maximum application consistency and compatibility between the
Windows and Wind/U environments and enables Bristol Technology to
continually evolve their product in step with Microsoft's enhancements.

Joint customer studies are scheduled to be conducted in the 4th quarter of
1996.

S/390 is IBM's enterprise server and is the leader in providing large scale
commercial computing solutions for customers today and in the evolving
collaborative, network computing market of tomorrow. S/390 servers offer
customers open, client/server capabilities, continuous computing
reliability, scalability, and low total cost of operation.

Bristol Technology Inc. develops, markets, and supports the Wind/U family
of Windows and UNIX cross-platform development products. Founded in 1991
and based in Ridgefield, Conn., the company has posted an operating profit
for 16 consecutive quarters. In addition to Wind/U, its products include
HyperHelp, software for creating UNIX-based on-line help systems with
WinHelp functionality; and Xprinter, software for adding sophisticated
printing capabilities to UNIX-based applications.
