    REDMOND, Wash., Feb. 8 /PRNewswire-FirstCall/ -- Microsoft Corp.
 (Nasdaq:   MSFT) today announced that it has signed definitive agreements to
 acquire Sybari Software Inc., a leading provider of security products that
 help more than 10,000 businesses worldwide protect their messaging and
 collaboration servers from viruses, worms and spam. Microsoft will use this
 acquisition to further provide its enterprise customers with new solutions to
 help protect them from malicious software.

     "Enterprise customers face a complex set of attacks through their e-mail
 and collaboration infrastructure," said Mike Nash, corporate vice president of
 the Security Business and Technology Unit at Microsoft. "Through this
 acquisition, we're excited to be able to provide customers with a server-level
 anti-virus solution that delivers advanced file and content-filtering
 capabilities and the use of multiple scan engines. In this way, customers get
 choice, high-quality performance and the most up-to-date protection possible."
     The planned acquisition of Sybari Software will play a key part in
 Microsoft's enterprise security strategy, providing anti-virus technologies
 that shield communications servers and supply customers with multiple-engine
 protection that can help with increased detection rates of malicious software.
 In a recent ICSA Labs survey, e-mail attachments were cited as the means of
 infection in 88 percent of virus incidents in corporate environments, a clear
 indication that further innovation is required.
     "We've been able to provide sophisticated, comprehensive protection for
 millions of mailboxes worldwide, and we're excited that through the addition
 of Microsoft's expertise and contribution, these solutions will be available
 to even more businesses," said Robert Wallace, president and CEO of Sybari
 Software. "We're proud of the effectiveness of our antigen products in
 providing protection against malicious software."
     Sybari Software's products provide an additional layer of messaging
 defense, helping stop threats before they reach end users. Sybari Software's
 security solutions are deeply embedded within the server infrastructure they
 protect, providing a consistently high level of security while maintaining
 infrastructure reliability and performance.
     In addition, Microsoft's enterprise customers will see greater value from
 their security investments because a single Sybari Software product will work
 with multiple versions of Microsoft(R) Exchange and Lotus Notes. Therefore,
 when migrating from one version to the next, or deploying multiple versions
 long term, a company can see a lower cost of maintenance and support for the
 comprehensive protections that Sybari Software's technology can provide.
 Sybari also provides solutions for Microsoft Office SharePoint(R) Portal
 Server 2003 and Microsoft Windows(R) SharePoint Services.
     Microsoft's goal for helping to secure collaborative environments is to
 enable businesses to foster collaboration among employees and with partners
 through technology without exposing their networks and assets to attack by
 malicious code. This acquisition will put Microsoft in a better position to
 make that happen by focusing on the following areas:
     -- Layered defenses. It is common practice in business networks to use a
        set of layered defenses to improve protection against malicious code.
        Similarly, effective protection of collaborative environments requires
        layers of defense.
     -- Integration with infrastructure. The layers must be tightly integrated
        not only with each other, but with the rest of the infrastructure in
        the network. Without such integration, a security solution can be
        unmanageable, have poor performance and let attacks through.
     -- Protection from the latest threats. Malicious threats evolve quickly.
        Defenses must be updated often, and be backed by worldwide networks of
        researchers who will identify and develop protection measures against
        the latest threats before they have a chance to impact businesses.
     Terms of the acquisition were not announced. Sybari will maintain all
 current operations until regulatory approval.
