REDWOOD SHORES, CA, (OCTOBER 9, 1998) -- Centura Software Corporation
(NASDAQ:CNTR), formerly Gupta, announces the 1998 Centura Customer Conference to
be held at the Hyatt Regency Grand Cypress Resort in Orlando, Florida from
November 1st through November 4th, 1998.  Centura's annual business and
technology conference is a valuable forum for current Centura customers who
include IT directors, senior managers, ISVs, VARs, ISPs, and System Integrators.

The 1998 keynote speakers will include Guy Kawasaki and Elizabeth Barnett. 
Kawasaki, author of the soon-to-be-released RULES FOR REVOLUTIONARIES, is 
also the CEO of garage.com, a Silicon Valley based firm that assists 
high-tech start-ups.  In addition, Kawasaki was a columnist for Forbes and an 
Apple Fellow at Apple Computer, Inc. where he was instrumental in 
successfully launching and establishing the


                                      -26-



Macintosh computer.  Barnett is a vice president of Giga Information Group 
and specializes in IT architecture, application development, data management, 
and distributed computing.

According to Barnett, "Companies today face two application development
imperatives: improve productivity and time to market, while at the same time
improving the overall quality of the systems they deliver. Component-based
development (CBD) techniques that can incorporate custom developed, purchased,
and legacy applications will best achieve these goals. IT managers must be
prepared to make investments in three critical areas: technologies for
development and deployment; development processes to ensure productivity and
quality; and organizational changes to institute new positions and new
responsibilities within existing roles."

The conference will offer both technical and business sessions to showcase
Centura's current product features as well as upcoming enhancements and
additional offerings. This year's conference will focus on techniques and tools
for building applications from components, new Web Applications, and
microservers. Centura is also providing bonus master classes to offer attendees
the opportunity to expand their skills and strategic implementation of
distributed component computing.

"We are very excited about this year's event because it is the perfect forum to
demonstrate our commitment to our customers," explains Scott Broomfield, CEO of
Centura.  "In addition to showcasing forecasts from some of the industry's
leading influencers, we will have the opportunity to give our customers and
prospects a preview of what should prove to be an incredibly exciting year." 

The Technology & Solutions Fair, held in conjunction with the customer
conference, will feature exhibiting partners who are using Centura products to
gain a competitive advantage in their industry including Fecher Ralgan, Minolta
and Metex Systems.
