Mar 26, 2001, 00:00 ET from Caldera Systems, Inc.

    HANOVER, Germany, CeBIT, March 26 /PRNewswire/ -- Caldera Systems, Inc.
 (Nasdaq:   CALD) and The Santa Cruz Operation, Inc. (SCO) (Nasdaq:   SCOC) today
 announced the forthcoming release of Open UNIX 8.  By incorporating the Linux
 Kernel Personality (LKP) technology into the next release of the UnixWare(R) 7
 kernel, Open UNIX 8 will enable Linux applications to be deployed on top of
 the powerful and highly scalable UNIX kernel.  Caldera will become the owner
 of the UNIX kernel when the acquisition of the SCO Server Software Division is
 completed as estimated in the second calendar quarter of 2001.

     Open UNIX 8 will maintain compatibility and continuity with the UnixWare 7
 operating system while providing a complete Linux environment.  In addition,
 the product will incorporate support for the execution of unmodified Linux
 Intel(R) Architecture binaries, giving users, resellers and ISVs the best of
 both UNIX and Linux technologies.  The result is transparent execution of Open
 UNIX 8 (or UnixWare 7) applications and most Linux applications, which will
 run without modification or recompilation.
     "Open UNIX 8 is the first step in implementing the vision of the pending
 new company," said Ransom Love, president and CEO of Caldera Systems.  "It
 combines the heritage of UNIX with the momentum of Linux, and will be our
 premiere product for data intensive applications like database, email and
 supply chain management.  The incorporation of the Linux application engine
 into the UnixWare kernel essentially redefines the direction of the product,
 and motivates a new brand identity -- Open UNIX."
     "If you need to run a Linux application in a data center environment, Open
 UNIX 8 will fill the bill with the highest standard of reliability and
 scalability," said Dave McCrabb, president of the SCO Server Software
 Division.  "We are 'unifying UNIX with Linux for Business' and this product is
 a major proof point."
     "One of the strengths of UNIX is its ability to provide enterprise-class,
 data intensive applications," said Bill Claybrook, research director for Linux
 and UNIX of Aberdeen Group.  "Open UNIX 8 is positioned to play a significant
 role in bridging the gap to Linux implementation in a data center
 environment."
     The LKP technology in Open UNIX 8 will include the same GNU tools and
 libraries built into Caldera OpenLinux(TM), which were developed with close
 adherence to the specifications of the proposed Linux Standards Base (LSB).
 Open UNIX 8 will track this developing standard, assuring the highest degree
 of application compatibility.
     Open UNIX 8 will be demonstrated at Caldera's booth at CeBIT in Hanover,
 Germany, March 22-28, Hall 3 Stand C45.  An Early Availability Program is in
 place to supply selected partners with LKP technology previews based on
 UnixWare 7.1.1 systems.  In April, Caldera and the SCO Server Software
 Division will begin distributing Open UNIX 8.0 beta versions to a broad list
 of partners.
     The product is targeted to be available mid-year and will include
 additional enhancements and refinements to the UNIX platform, representing an
 additional value for existing UnixWare 7 customers.  Open UNIX 8 will be
 available to UnixWare 7 customers as a system upgrade.
