SCO Announces Availability of OpenServer Kernel Personality on UnixWare(R)

OpenServer Kernel Personality (OKP) for UnixWare 7.1.3 Leverages the
Components of OpenServer and UnixWare for Greater UNIX(R) Scalability,
Extending the Reach of OpenServer Applications - Giving OpenServer
Customers More Choices

LINDON, Utah, July 31 /PRNewswire-FirstCall/ -- The SCO Group, Inc.
(Nasdaq: SCOX), the owner of the UNIX(R) operating system, today announced
the availability of OpenServer Kernel Personality (OKP) for customers who
want the additional power of UnixWare(R) for their OpenServer applications.
Building upon the reliability of OpenServer, UnixWare provides the
capability for OpenServer applications to leverage the increased
scalability, performance,CPU support, and clustering technology available
for UnixWare without the need to invest in costly migration projects.

OKP contains Xenix compatibility and supports OpenServer 5.0.4, 5.0.5,
5.0.6 and the latest 5.0.7 release. Many applications that were written
for current and older versions of OpenServer, including SCO UNIX, SCO
OpenDesktop, that run on OpenServer 5.0.4 or later release, will run on
OKP."OpenServer has an excellent track record and reputation for
reliability and availability and it continues to be developed and
maintained. OKP on UnixWare helps customers gain greater uptime because
UnixWare 7.1.3 supports hot plug CPU, hot add memory, and hot plug PCI thus
eliminating unnecessary downtime," said Janet Sullivan, Senior Manager,
Product Marketing, for SCO. "For customers that have a need for these
benefits, OKP is ideal because it protects your investment in OpenServer
applications and avoids costly end-user re-training."

"OKP provides more choices for OpenServer customers," said Jeff Hunsaker,
senior vice president of marketing, SCO. "They can choose to continue to
update their OpenServer environments, or they can use UnixWare 7.1.3 with
OKP. Either way, the customer is assured that their investment in
OpenServer applications is protected."

Some of the additional benefits that customers will gain using OKP on
UnixWare 7.1.3 are:

-- Increased reliability through the use of Reliant HA Clusters on
UnixWare
-- Support for up to 32 CPUs per server
-- Increased performance of UnixWare
-- Ability to consolidate physical or logical workloads on fewer, more
powerful servers
