PROFESSIONAL CADAM ADDED TO SUN'S GROWING PORTFOLIO
OF MECHANICAL CAE/CAD/CAM SOLUTIONS
 
Strong Endorsement of Sun's Open Systems Philosophy
 
MOUNTAIN VIEW, Calif.,--February 21, 1989-- With the addition today of
PROFESSIONAL CADAM for its Sun-4(TM) workstation family, Sun
Microsystems continues to provide the mechanical CAE/CAD/CAM community
with the broadest portfolio of UNIX(R)-based application solutions.

CADAM's introduction of a hardware-independent version of its industry
leading software marks the first time that its products have been
available for UNIX workstations.  Because of CADAM's prevalence in
automotive, aerospace and manufacturing industries worldwide,
PROFESSIONAL CADAM is an important product for Sun in the U.S., Europe
and Japan.

"We consider CADAM's strategy of providing a UNIX-based solution for
multi-vendor, heterogenous CAE/CAD/CAM environments a strong
endorsement of Sun's open systems and industry standards philosophy,"
said Scott McNealy, president of Sun Microsystems.  "Sales of
PROFESSIONAL CADAM seats could represent some $75 million in Sun sales
over the next three years," continued McNealy.

Unique Relationship

While PROFESSIONAL CADAM is available for several UNIX workstations,
Sun offers a broader range of RISC technology, networking capabilities
and distribution channels.

PROFESSIONAL CADAM is aimed at users of Sun-4/150 CXP and 4/260 CXP
graphics workstations, both based on the company's SPARC (scalable
processor architecture) RISC microprocessor.  Software development was
completed using SunOS(TM) Release 4.0.  As a result, PROFESSIONAL CADAM
can be adopted easily to future SPARC offerings.

Sun offers superior connectivity for PROFESSIONAL CADAM users through
its range of networking services and protocols, including its
ONC/NFS(TM) (Open Network Computing/Network File System) standard.
ONC/NFS enables users to link disparate systems--such as workstations
and mainframes--into the corporate networks they demand.  This is
especially important to CADAM users who have exisiting mainframe
installations.

Sun's connectivity solutions were recently expanded with the creation
of MVS/NFS, a joint development of Sun and Electronic Data Systems
(EDS), bringing the functionality of NFS to IBM's MVS mainframe
environment.  With MVS/NFS, any computer supporting NFS, from PCs to
supercomputers, will have high-speed transparent access to information
residing in IBM or compatible mainframes.

PROFESSIONAL CADAM for Sun workstations will be sold by CADAM's direct
sales force and through combined Sun/CADAM VARs.  Sun has more than 150
VARs throughout the country. Many of these VARs will resell Sun/CADAM
solutions.

CADAM, INC, a Lockheed Company, has developed a complete family of
integrated CAE/CAD/CAM software packages suitable for various hardware
platforms.

Sun Microsystems, Inc., headquartered in Mountain View, Calif., is one
of the world's leading suppliers of network-based distributed computing
systems, including professional workstations, servers and UNIX
