            CENTURA SOFTWARE CORP. INTRODUCES NEW DATA REPLICATION TOOL
                                          
                  SQLBASE EXCHANGE OFFERS DEVELOPERS UNPARALLELED 
                             FLEXIBILITY AND OPENNESS 

REDWOOD SHORES, CA AUGUST 10, 1998 --- Centura Software Corporation (NASDAQ: 
CNTR / formerly Gupta Corporation) today extends its RDBMS product family, 
SQLBase, with the release of SQLBase Exchange, an automated data moving tool. 

As an add-on to Centura's SQLBase database, SQLBase Exchange provides an 
effective solution for developers who are creating applications with data 
replication requirements.  Centura's SQLBase Exchange is the first in a 
series of upcoming SQLBase product offerings, designed to address the 
embedded database needs of MIS departments and application developers.  

"As the arena of distributed business becomes more automated, the access and
movement of data and functions in remote locations is critical to global network
success," explains Kathy Lane, senior vice president of marketing and strategic
alliances for Centura. "SQLBase Exchange's technology allows developers to move
data between SQLBase databases and between SQLBase and a wide variety of
databases."

SQLBase Exchange is a data-oriented technology as opposed to a 
transaction-oriented one. This new product effectively accommodates all basic 
types of data movement, including data consolidation, data dissemination and 
one-to-one data transfer.  SQLBase Exchange optimizes data movement by giving 
developers unrivaled freedom to shift data between SQLBase and a wide variety 
of databases, increasing the appeal of SQLBase to developers creating 
applications for distributed deployment.

"SQLBase Exchange provides a level of flexibility and openness that simply does
not exist in competing solutions," states Max Stayner, Centura's Director of
SQLBase products.  "Unlike Sybase's SQL Anywhere, which can only replicate with
Sybase's databases, SQLBase Exchange allows developers to choose from virtually
any data format.  As a result, developers are not restricted to one vendor's
technology." 
 
SQLBase Exchange eliminates large amounts of low-level coding without
sacrificing developers' control and flexibility.  With SQLBase Exchange,
developers have the freedom to move data according to their business rules while
enjoying the benefits of less coding.  

PRICING AND AVAILABILITY

Pricing for SQLBase Exchange starts at $249 per client desktop, with other
packages available for deployment and server support.  SQLBase Exchange is
available direct from Centura.  For more information regarding sales, please
