RELAY GAINS ENTRY TO CLIENT/SERVER MARKET WITH RELAY/OPENPORT

PC-BASED WINDOWS PRODUCT LOADS ON CLIENT; OFFERS MOST RELIABLE MOVEMENT OF
DATA BETWEEN RELATIONAL DATABASES

NEW YORK -- June 28, 1994 -- Relay Technology, Inc., of Vienna, VA, is
using their position as the leading SQL/DS supplier of Database
Administration tools to gain entry into the client/server arena with the
introduction of Relay/OpenPort, a PC-based Windows product enabling Data
Administrators to move data and data structures from one relational
database to another quickly and reliably.

Relay/OpenPort is designed for organizations needing to port SQL database
data from one platform to another; e.g, SQL/DS to Sybase, but do not want
to incur heavy financial and time costs to implement a network and the
associated software to provide data access on disparate platforms.
Moreover, companies with a need to off-load data from a number of
different SQL database types to a single one on a scheduled basis, and/or
archive or periodically update their databases will find Relay/OpenPort
the perfect cost-effective vehicle for doing so.

Available later this year, Relay/OpenPort initially will allow Data
Administrators to port SQL database data from or to the most popular
databases, including SQL/DS, Sybase, Oracle, SQL Server, DB2/2, DB2/6000
-- where they want it, when they want it and how they want it.

Along with moving data back and forth between relational databases,
information about the way the data is structured may be moved as well.
This results in the complete automation of the process so that data and
databases can be moved by non-technical personnel when they need it --
even as constant changes occur. Moreover, Relay/OpenPort lets Data
Administrators take the entire database or subsets to create new ones that
enable companies to focus better on present and future needs.

Relay's President and CEO Bruce Mancinelli stated, "The movement and
management of database data and databases between the mainframe and the
workstation (client)/server level presents a unique opportunity for Relay
to take advantage of its knowledge of the mainframe environment, SQL and
connectivity between host systems and PCs to provide data administrators
with reliable solutions. Initially, the SQL/DS market will be the
beneficiary of Relay/OpenPort, the first phase of a cost-effective suite
of products to facilitate database data as well as non-database data
porting," he added. "Relay/OpenPort is the first product to fill the gap
between the lack of user expertise and the need to have data accessible
and portable."

THE DESKTOP ENGINE

The desktop engine is the Relay/OpenPort client which processes the
specifications through a graphical user interface (GUI) for the porting
engine to use to convert data and data structures from the source to the
target databases.

Relay/OpenPort is Windows based, enabling the Data Administrator to "walk
through" the process as the desktop engine builds the specifications
script. In this way, the correct SQL statements are generated for the
porting engines to convert the data types and build database structures --
either creating new databases, appending and/or replacing existing ones.
The porting engine then processes the specifications script.

In direct mode, Relay/OpenPort dynamically converts the data structures,
creates and issues the correct SQL statements to fetch the data from the
source database, then dynamically inserts, updates or replaces row data in
the target database. In export-import mode, the porting engine performs
the fetch, placing the data in a file and creating a specifications script
for the target server to insert, update or replace the data row-by-row.

A communications interface provides seamless support of SQL/DS gateways,
Relay Technology's own host gateway (Relay/PC Gold) and LAN communications
protocols such as Sybase and Microsoft NET-LIB and Oracle SQL*NET. In
Relay/OpenPort's first phase, data transfer will take place through the
Desktop Engine.

PORTING

Relay/OpenPort will port database objects such as tables, indexes, views,
permissions, procedures, etc., between different types of databases and
database servers. Relay/OpenPort has its own built-in scheduler and
supports popular servers like Sybase, Microsoft SQL Server, Oracle, DB2/2,
DB2/6000 and SQL/DS.

Three porting models will be supported: (1) Direct - read from one table
and write to another; (2) Export - read from one table and write to a flat
file; and (3) Import - read from a file and write to a table. With the
server-database, many-to-many table ports will be supported.
Relay/OpenPort has the ability to subset tables by columns and rows and
automatically handle data type conversions and/or allow users to specify
conversions.

MAINFRAME SUPPORT

Relay/OpenPort will support SQL/DS on the VM mainframe through a Host
Transfer/Service Virtual Machine (HT/SVM). The HT/SVM incorporates Relay's
data transfer technology to facilitate access to SQL/DS databases and
transferring information and database data -- providing both DRDA and
non-DRDA connectivity solutions.

DESKTOP (WORKSTATION) SUPPORT

Relay/OpenPort is a Windows-based client resident application; it is
connected to the server via normal SQL Net-type connections.

GATEWAY SUPPORT

Replay/OpenPort supports Replay/PC Gold for Windows 6.0. It is ODBC
compliant.

SALES STRATEGY

Relay/OpenPort will be aggressively priced. It will be available through
system integrators (SI), direct sales and major account sales. SIs will be
selected based on their depth of experience and knowledge of database and
application migration from mainframes to LAN-based client/server
platforms.
