WESTLAKE VILLAGE, CA and PARIS, FRANCE -- September 10, 2002 -- Xplain
Corporation, the leader in pavilion management, unveiled today two new
pavilions at Apple Expo, in Paris (10-14 September, 2002). These two
special interest areas will bring technical tools to the Paris show, as
well as help introduce many international publishers to the European market.

Apple Expo, Europe's premier Macintosh event, takes place from September 10
- 14, 2002, and takes place at Porte De Versailles in Paris. See

Special Interest Pavilions, including Xplain's long running MacTech
Central(sm), have long featured both up-and-coming companies, as well as
showcased technologies. These pavilions provide exhibiting companies with
a cost-effective, turnkey method to reach their target audiences
face-to-face without requiring a large staff or display. In turn, attendees
with particular interests can experience first-hand the very latest
Macintosh technology for specific market segments in a cohesive setting.
