Google to Acquire Postini

Google to Acquire Postini a global leader in on-demand communications security and compliance solutions serving

MOUNTAIN VIEW, Calif. – July 9, 2007 – Google Inc. (NASDAQ: GOOG)
announced today that it has signed a definitive agreement to acquire
Postini, a global leader in on-demand communications security and
compliance solutions serving more than 35,000 businesses and 10
million users worldwide.

 Postini’s services — which include message
security, archiving, encryption, and policy enforcement — can be used
to protect a company’s email, instant messaging, and other web-based
communications. Under the terms of the agreement, Google will acquire
Postini for $625 million in cash, subject to working capital and other
adjustments, and Postini will become a wholly-owned subsidiary of
Google. The agreement is subject to customary closing conditions and
is expected to close by the end of the third quarter 2007.

“With this transaction, we’re reinforcing our commitment to delivering
compelling hosted applications to businesses of all sizes. With the
addition of Postini, our apps are not just simple and appealing to
users — they can also streamline the complex information security
mandates within these organizations,” said Eric Schmidt, Chairman of
the Board and Chief Executive Officer of Google.

Hosted services, like Google Apps and Postini solutions, provide
organizations with high quality communications tools without the
expense and hassle of traditional on-premises solutions. Google Apps,
which includes Gmail, Calendar, Talk, Docs & Spreadsheets, and
Personal Start Page, has been adopted by more than 100,000 businesses
already. Postini solutions include Email Security, IM Security, Web
Security, Message Archiving, Message Encryption, and Policy-enforced
TLS.

“The response to Google Apps has been tremendous, with more than 1,000
small businesses signing up for the service every day. At the same
time, large businesses have been reluctant to move to hosted
applications due to issues of security and corporate compliance. By
adding Postini products to Google’s technology, businesses no longer
have to choose — employees get the intuitive products they want, and
the company achieves the security and assurance it needs,” said Dave
Girouard, Vice President and General Manager, Google Enterprise.

“As the market leader in on-demand secure communications and
compliance solutions, Postini complements Google perfectly. We share a
commitment to providing enterprise customers with compelling
technology alternatives. This is an exciting milestone, one that will
certainly lead to the next level of rapid innovation,” said Quentin
Gallivan, President and Chief Executive Officer of Postini.

“Postini’s founding vision is to bring to market technology solutions
that address enterprise messaging problems in a different way. Our on-
demand offering liberates businesses from the burdens associated with
traditional on-premise solutions. We are proud of what we have done to
achieve our vision on behalf of our customers, and combining Google
and Postini is a powerful next step in this creative journey,” said
Scott Petry, Founder, Chief Technical Officer, and Executive Vice
President of Product Development at Postini.

Google will continue to support Postini customers and invest in
Postini products.

The Google Enterprise group makes popular Google technology available
to businesses of all sizes — from small, two-person startups to some
of the largest companies in the world.  Google Enterprise products
help businesses find, see and share information through products such
as Google Search Appliance, Google Mini, Google Earth, Google Maps and
the Google Apps suite of hosted applications.
