    Business Editors/High-tech Writers

    SAN MATEO, Calif.--(BUSINESS WIRE)--July 14, 2000--AvantGo, Inc., a mobile Internet
company, today announced that AvantGo Enterprise(TM) will be demonstrated during Microsoft's
Fusion conference, July 15-17, by Microsoft Corporation's SQL Server group as part of its mobile data
warehousing solution. AvantGo Enterprise solutions enable organizations to extend interactive enterprise
applications and data beyond the desktop to mobile workers, through either a wireless connection or
through desktop synchronization.

    The Microsoft demonstration, "Business Intelligence on the Road," highlights Microsoft and AvantGo
products working together to deliver business intelligence reports to Windows-Powered Pocket PC
devices. The solution invokes SQL Server OLAP Services cubes, runs queries and renders corporate
data onto mobile devices, either live or cached for disconnected use.

    "Microsoft is dedicated to delivering quality business intelligence capabilities and with AvantGo
Enterprise we are able to extend those capabilities to Pocket PC devices," said Steve Murchie, Group
Product Manager at Microsoft. "Organizations are looking for ways to extend their most demanding
analytical applications to mobile devices and we are pleased to be working with AvantGo to meet our
enterprise customers' needs."

    "Our customers' businesses are moving at lightening speed and the companies that are going to
remain competitive and succeed are those that can give employees -- whether they are executives or
field workers -- the right information they need to excel where and when they need it," said Rob
Meinhardt, vice president of enterprise marketing at AvantGo. "Microsoft's data warehousing and
business intelligence solutions unlock corporate data and turn it into useful information, and AvantGo
Enterprise takes that powerful data and puts it at the fingertips of the workforce."
