WESTLAKE VILLAGE, CA -- February 21, 2003 -- Xplain Custom Services today
announced the return of the popular "WWDC Exhibit Fair" to Apple's
Worldwide Developers Conference, May 19-23, at the San Jose Convention
Center. Vendors in the WWDC Exhibit Fair have a unique opportunity to
showcase their latest technical products to the thousands of Mac OS X
developers who attend this annual event. In 2003, the WWDC Exhibit Fair has
expanded to include products and services for Enterprise IT organizations
as well as QuickTime content creators.

"The WWDC Exhibit Fair is always the focal point for seeing the latest
technical wares on the Mac," said Neil Ticktin, CEO of Xplain Corporation
and Publisher of MacTech Magazine. "With its expanded focus this year, WWDC
Exhibit Fair will have vendors showing off the best the Mac has to offer to
IT professionals and content authors as well as traditional developers."

"The WWDC Exhibit Fair provides Sybase with an excellent opportunity to
showcase the first enterprise database to port to Mac OS X, Sybase(r)
Adaptive Server(r) Enterprise 12.5," said Kathleen Shepherd, Field
Marketing Manager, Sybase, Inc. "Developers at the event will learn how
they can gain the full benefit of Sybase ASE's advanced capabilities,
including leading Java and XML support, and can take advantage of ASE's
support of applications developed in Apple's WebObjects development
framework. We look forward to sharing with delegates from all over the
world how Sybase, in concert with leading companies like Apple, helps
customers attain maximum value from their data assets by getting the right
information to the right people at the right time."

"WWDC has been a great show for Perforce. The conference attracts a highly
qualified audience of Mac developers who are actively looking for resources
to help them with their jobs." said Sutter Schumacher, Marketing
Coordinator, Perforce Software. "As a software development tool vendor, we
can't recommend it highly enough."

The WWDC 2003 Exhibit Fair provides the perfect venue for companies to
cost-effectively reach the Mac developer community face-to-face. Exhibitors
get to show developers from around the world the very latest products that
support Mac OS X development and Apple's innovative technologies.
