 FOR IMMEDIATE RELEASE

 CALDERA RELEASES OPENDOS KERNEL SOURCE TO THE INTERNET Distribution of
 OpenDOS Kernel Unprecedented in Computer Industry

 PROVO, UT--April 30, 1997--Caldera Inc. today announced that it will
 release (via FTP and CD ROM) its OpenDOS kernel source on May 5, 1997.
 This release makes software history by freely distributing the source
 code to the most popular operating system in the world. Far from dead,
 DOS is still the underlying programming architecture found on high and
 low-end PCs worldwide. According to the CI (Computer Intelligence)
 Consumer Technology Index, 1996, nearly 68% of all used and acquired PCs,
 are 386 or lower. Research from Goldman Sachs underscores that statistic,
 citing an estimated PC installed base of 85 million: 25 million running
 486's and 386's with an additional 37 million running 286's.

 Caldera's release of the OpenDOS kernel source and OpenDOS 7.01 binaries
 to the Internet allows companies and individuals to use and develop
 OpenDOS for future use in their own products. OpenDOS also enhances the
 ability of embedded systems like Network Computers, NetPCs, kiosks, etc.
 by allowing OEMs and VARs to use well-known technology as a base for
 their own solutions.

 "The DOS kernel source allows everyone from OEMs to end users to
 customize OpenDOS technology for their own specific needs," commented
 Bryan Sparks, President and CEO for Caldera Inc. "They can create their
 own innovative and low-cost custom solutions. All users benefit by being
 able to optimize investments in existing hardware and applications."

 OpenDOS source and OpenDOS binaries are free, and may be downloaded for
 educational and non-commercial use.

 By providing the source and binaries to the OS technology that fueled the
 PC revolution, Caldera supports the efforts of educators worldwide to
 increase technology comprehension at all levels.

 The OpenDOS binary is based on DOS 7 technology acquired by Caldera from
 Novell in 1996, and provides a mainstream, no-cost OS for research and
 education.

 OpenDOS also provides a complete operating system supporting all
 DOS-based applications and low-cost commercial integration into the
 OpenLinux environment for OpenLinux users.

 In addition, it is fully compatible with MS-DOS and supports Microsoft
 Windows (3.1 and 3.11), and networking systems that include Novell
 NetWare, Windows for Workgroups and LANtastic. The OpenDOS kernel source,
 OpenDOS 7.01, Caldera Source Usage License with full HTML user and
 programmer documentation, plus floppy disk install options are all
 included on the CD-ROM. (Floppy disks may be created from disk images
 contained on the CD for installation on PCs without CD-ROMs.) A
 commercial license for OpenDOS may be obtained by purchasing the CD-ROM.

 7.01 will be available at a special introductory price of $19.99 (in the
