UNIX Outperforms NT in Ziff Davis ServerBench Tests

Customers Can Rely on UNIX for Top Performance and Scalability on
Industry-Standard Hardware

FLORHAM PARK, New Jersey --October 27, 1995--UnixWare 2 and SCO OpenServer
Release 5, both leading business-critical application server operating
systems, outperformed Microsoft NT in ServerBench tests conducted recently
by Ziff Davis Labs. Conducted on a Compaq ProLiant 4000 with up to four
Pentium/66 processors, these tests simulate a database application's
activity, measuring the number of transactions between networked clients
and servers -- based on a mix of processor, disk and network subsystem
tests.

UnixWare 2 led the pack in performance and scalability with multiple
processors (one to four), and also was top data cruncher -- turning in the
best ServerBench scores by client load and number of processors. SCO
OpenServer Release 5 turned in the second best performance, also
confirming the UNIX system as the clear winner against Microsoft NT in its
ability to meet the business-critical computing needs of enterprise
customers.

Running on industry-standard hardware, UnixWare 2's top performing score on
the single processor includes a peak of 41 transactions per second (TPS)
with an average score of 35 TPS across the full client range. SCO
OpenServer Release 5 averaged 28 TPS. Windows NT and OS/2 followed, with
25 TPS and 20 TPS, respectively.

On September 20, Novell announced plans to sell its UNIX business to The
Santa Cruz Operation, Inc., (SCO) and acquire a significant minority
position in SCO. Effective on or about December 1, SCO will market and
sell UnixWare 2 and ship the general release of UnixWare 2.1 mid year in
1996. SCO also will be merging the best features of its SCO OpenServer
Release 5 with UnixWare 2 into one application server product expected to
ship during 1997.

"We are extremely pleased that UnixWare 2 turned in such excellent scores
in its first head-to-head performance competition against Windows
NT,"stated Rick Bohdanowicz, vice president, product marketing, Novell's
operating system division." "Enterprise customers seeking a truly superior
and highly scalable application server should clearly consider the UNIX
system as the proven solution for business-critical computing."

UnixWare 2 is the latest generation of UNIX System V technology, a platform
for popular commercial applications that has been evolving for more than
20 years. As an application server platform designed for business-critical
systems, this new version gives customers a powerful, cost-effective
system to meet their needs for high performance, scalability, NetWare
integration, ease of use and administration, and broad applications
support (more than 3,500 native and 15,000 UnixWare-compatible
applications exist today).

"The excellent performance and scalability of both SCO OpenServer Release 5
and UnixWare clearly demonstrate two of the advantages that UNIX systems
offer over competitive platforms. These, combined with the enormous base
of business-critical applications and databases, clearly show UNIX system
superiority in bringing enterprise level capabilities to business
environments of all sizes, " noted Scott McGregor, senior vice president,
products, SCO.

SCO OpenServer Release 5 is the next-generation Business Critical Server
operating system for the Intel platform that protects customers' legacy
investments in data, applications, networks, and hardware. Advanced
reliability, availability, and scalability features are built-in, enabling
businesses of all sizes to combine the power and security of large-scale
systems with the exceptional price-performance value and flexibility of
commodity server hardware based on Intel microprocessors.
