DUBLIN, Calif. – May 6, 2002 – Sybase, Inc. (NYSE: SY), a leading
enterprise infrastructure and integration company, announced today the
availability of Open Client and Open Server for Mac OS X. These versatile
programming tool kits for developers are an enterprise-class database
solution to deliver Mac applications across a variety of database systems.

“Open Client and Open Server for Mac OS X bring the power of Sybase’s
enterprise-class database management technology to the Mac community,” said
Dr. Raj Nathan, senior vice president and general manager, Sybase
Enterprise Solutions Division. “With the availability of Open Client and
Open Server for Mac OS X, development of mission-critical, enterprise-class
applications can take place directly on Mac OS X.”

“Offering unprecedented stability, power and interoperability, beneath the
elegant Aqua user interface, Mac OS X is a super platform for building
robust and reliable applications,” said Ron Okamoto, Apple’s vice president
of Worldwide Developer Relations. “Mac developers will be very excited to
have access to such exceptional database technologies from Open Client and
Open Server to create high performance applications for demanding computing
environments.”

Sybase Open Client for Mac OS X provides Mac OS X client seats with a high
performance connection to an installed base of more than 40,000 corporate
systems running more than one million databases managed by Sybase Adaptive
Server Enterprise (ASE). Open Client acts as a bridge between the
applications developed on Mac OS X and Sybase’s enterprise-class products
including the Sybase ASE database manager and middleware, such as Sybase’s
DirectConnect(tm) family of products. Together with DirectConnect, Open
Client allows a developer to tap into legacy enterprise databases running
on Compaq, Hewlett-Packard, IBM, Silicon Graphics and Sun servers.

“REALbasic=AE customers crave high performance connectivity to Sybase
database products,” said Lorin Rivers, vice president of marketing, REAL
Software. “With the introduction of Open Client for Mac OS X, this high
performance connectivity is one step closer.”

Sybase Open Server is a highly configurable server tool kit that greatly
simplifies the design and implementation of server applications. With Open
Server, programmers can extend the value of existing applications by
allowing them to be used with Open Client-based applications as well as
integrate legacy databases into the client/server environment. Sybase Open
Server provides an ideal platform for developing gateways to many forms of
data in existing systems. Together Open Client and Open Server provide a
unified application program interface for accessing data and services.

“Mac OS X is gaining ground in the enterprise space,” said Michael Kelly,
chairman and chief architect of Techtel Corporation, a technology market
research firm based in Emeryville, Calif. “In fact, among the largest
buyers of enterprise technology, Mac OS X has a higher customer
satisfaction than both Windows=AE 2000 and Linux=AE.”

Open Client and Open Server for Mac OS X are available immediately and
