Sybase 365 Offers Microsoft Windows Live Messenger Service to Mobile Operators in South East Asia

Service Dramatically Simplifies Proposition for Global Mobile Operators to
Provide Instant Messaging Services to Their Subscribers
DUBLIN, Calif.--(Business Wire)--
Sybase 365, a subsidiary of Sybase, Inc. (NYSE: SY), the global leader in mobile
messaging services, today announced an agreement to resell Microsoft Windows
Live Messenger services to its mobile operator customers in South East Asia,
providing them a simplified way to offer the popular Windows Live Instant
Messenger for Mobile to millions of mobile subscribers. The agreement builds on
the five year collaboration between the two companies on services including
Windows Live Hotmail mobile.

"This agreement is a natural extension of our ongoing partnership with
Microsoft," said Howard Stevens, senior vice president International Operations,
Sybase 365. "Our goal is to continue to provide a win-win situation for our
customers-be they mobile operators or the independent software vendors-by
providing value and revenue for all parties. We are excited to be a part of
bringing one of the Internet`s most popular services to millions of mobile
devices around the world."

As consumer demand continues to build for mobile messaging services beyond text,
the next logical areas of focus are multi-media messaging (MMS) and mobile IM
services. The Windows Live community is already one of the largest on the
Internet with more than 550 million users and will continue to grow as it
becomes more readily deployed on mobile devices worldwide.

Sybase 365 operator customers offering the service include Singapore`s StarHub
and Malaysia`s DiGi Telecommunications Sdn Bhd. DiGi recently launched the
country`s first integrated IM mobile client allowing subscribers to access
Windows Live Messenger and other IM services on their mobile phones.

The service is being offered initially in South East Asia and will be rolled out
in other countries throughout the year.
