     SMCC AND CORAL SYSTEMS TEAM UP TO FIGHT CELLULAR FRAUD

MOUNTAIN VIEW, Calif. --June 8, 1992-- Sun Microsystems Computer
Corporation (SMCC) and Coral Systems Inc. have signed an agreement to
jointly market Coral's "Intelligent Network" solution for cellular
service providers internationally. Under the agreement, two new
products, called HLR (Home Location Register) and FraudBuster, will be
introduced at the end of 1992. The products will run on the Sun
SPARCserver 600MP(TM) series and the Solaris(R) environment.

With the tremendous growth in the wireless industry over the past five
years and the decreasing costs a carrier can charge for service,
competition has forced carriers to differentiate themselves through
better customer service, enhanced service functionality and network
reliability.  Coral's wireless network software will give cellular
service providers the ability to offer their customers more services,
as well as protect themselves against revenue loss resulting from
fraud.

"Coral's products and Sun technologies are a winning combination," said
Eric Johnson, Coral's president and CEO. "SMCC's strong distributed
application environment, price/performance and client-server
architecture are a good match with Coral's software solutions."

The SPARC(R)/Solaris platform is being used by software providers, like
Coral Systems, and carriers doing in-house development to build the
components of an Intelligent Network. The Intelligent Network
architecture, embraced by the telephone industry, consists of a
switching system, a signaling system (SS7), a central database, and a
support system for the database.

"It is SMCC's goal to provide telecommunications companies with the
distributed computing platform that is needed to design new services
that migrate the intelligence of the system as close as possible to the
customer," said Bruce Golden, director of commercial market development
at SMCC. "Coral's solution is an example of the implementation of a
client-server architecture within the Intelligent Network framework."

Coral's HLR (Home Location Register) software transparently routes
calls to any subscriber, regardless of location. Carriers will be able
to generate additional revenues by attracting more subscribers, who
will be able to use their equipment in a broader geographic area.
Fraudbuster detects and prevents fraud through pre-call (with HLR) and
post-call verification and authorization of cellular calls.  Cellular
fraud is a serious problem for carriers. It is estimated that over $600
million is lost in revenues each year due to fraud.  Coral's beta
software on the Sun SPARCserver 600 MP(TM) Series has already detected
the most common types of wireless fraud, including subscriber fraud,
clone phones and tumbler phones.

"After evaluating the needs of the highly competitive cellular market,
we are confident that our partnership with SMCC will provide customers
with the strategic solution necessary to meet industry challenges,"
said James E. Blake, chairman of the board at Coral Systems.

Coral Systems, Inc. is a UNIX software house focused on the wireless
telecommunications industry.  The Coral modular services platform is
designed to bring Intelligent Network (IN) call handling capabilities
to existing cellular operations and emerging personal communications
services (PCS). Other Coral products in development include Data
Message Handler (DMH) and Visitor Location Register (VLR). The company,
founded in 1991 and headquartered in Boulder, Colorado, is doing
business worldwide with its strategic partners Sun Microsystems
Computer Corporation and CSC Intelicom, a company of Computer Sciences
Corporation.
