SUN MICROSYSTEMS, INC. COMBINES SUNSELECT AND SITKA CORPORATION 

Combined Business Unit Integrates Complementary PC Networking Product
Lines; Operates Under SunSelect Name

MOUNTAIN VIEW, Calif.--December 15, 1992--Sun Microsystems, Inc. today
announced that it intends to compete more aggressively in the PC
networking market by combining the operations of two of its businesses:
SunSelect and Sitka Corporation. The combined business unit integrates
SunSelect's open, client-server networking and emulation product families
with peer-to-peer and mobile networking product lines from Sitka.

"Peer-to-peer, client-server, and mobile networking are among the fastest
growing PC networking segments today," said Scott McNealy, chairman and
chief executive officer of Sun Microsystems, Inc. "Combining the two
business units makes SunSelect extremely competitive against leading PC
networking vendors in all three areas."

The worldwide operations of the combined business will be headquartered in
Chelmsford, Mass., with additional offices in Alameda, Calif., Bagshot,
U.K., and Tokyo, Japan. The integrated enterprise will carry the SunSelect
name and will be directed by Carl S. Ledbetter, vice president of Sun
Microsystems, Inc. and general manager of SunSelect. Sitka products will
continue to be sold and supported through existing Sitka channels. The
integrated SunSelect is committed to the established strategic business
relationships of both companies, and will continue the level of service
and support that customers have come to expect. The transition is
scheduled to take effect on December 28, 1992.

"By combining the two business units, Sun now offers customers a broader
range of solutions for their PC networking needs--all from a single
source," said Carl S. Ledbetter. "Today's announcement also means that
SunSelect now offers customers the combined service and support
capabilities of two strongly service oriented businesses."

"This is an exciting development since both companies are committed to
providing open, cross-platform solutions," said Deborah Triant, president
and CEO of Sitka Corporation. "Together, we can offer users a powerful way
to maximize resources regardless of platform or operating environment."

The Combined Product Family

The Sitka product line provides cross-platform peer-to-peer networking, and
connectivity products for mobile and pen-based computer users. The Sitka
products, SitkaTOPS, PenTOPS, PenCentral, and Sitka 10NET, make it easy
for computer users on different computer platforms to share resources with
other systems on a network. The combined SitkaTOPS and 10NET installed
base exceeds one million nodes.

SunSelect's products complement the Sitka line by adding powerful
alternatives for integrating PCs into open network environments. With one
million installed nodes, SunSelect's PC-NFS software is now the industry's
most widely used PC-to-enterprise networking solution. SunSelect also
markets NetWare SunLink software, which integrates the most popular LAN
with the industry's leading workstations, and SunPC software and hardware
acceleration products for running MS-DOS and Microsoft Windows
applications on SPARC workstations.
