Sun to Acquire Aduva

Technology To Be Embedded within the Solaris Operating System, Furthering

Sun's Strategy to Offer IT as a Sun Grid Service

Feb 22, 2006, 00:00 ET from Sun Microsystems, Inc.

    SANTA CLARA, Calif., Feb. 22 /PRNewswire-FirstCall/ -- Sun Microsystems,
 Inc. (Nasdaq:   SUNW) and Aduva today announced that they have entered into a
 definitive agreement pursuant to which Sun will acquire Aduva. Aduva
 technology allows enterprises to automate the processes associated with patch
 and dependency management -- providing a solution that scales from individual
 servers, up to large scale data centers with tens of thousands of machines in
 complex networks. Aduva currently runs an active dependency service for
 Solaris and Linux servers, easing the burden on systems administrators
 deploying a continuous stream of patches, updates, and changes required
 throughout the data center lifecycle. Aduva's multi-platform services will be
 available for operation by individual customers behind their own firewalls, or
 as an automated service from Sun's Grid.
     "By acquiring Aduva, Sun will be addressing the number one pain point we
 hear from IT administrators -- patch management -- while addressing the
 principle cause of service downtime and system vulnerability: out of date
 systems and patches," said Don Grantham, executive vice president of Sun
 Services. "By integrating this technology into our offerings and services, Sun
 can enable customers to update thousands of systems at the touch of a button."
     Grantham continued, "At Sun, we know how hard customers are working to
 reduce risk, increase compliance, and automate more manual jobs in the data
 center, as they rely on the network for a growing array of computing services.
 As the vendor most committed to delivering computing as a network service, Sun
 can deliver on even more compelling offerings with the addition of the Aduva
     The transaction is subject to customary closing conditions and is expected
 to be completed during the fourth quarter of Sun's 2006 fiscal year which
 begins on March 27, 2006. The terms of the deal were not disclosed as the
 transaction is immaterial to Sun's earnings per share.
     Safe Harbor
     This press release contains forward-looking statements that involve risks
 and uncertainties. These forward-looking statements include statements

 ability to deliver even more compelling offerings and the expected completion
 date of the acquisition. Such statements are just predictions and involve
 risks and uncertainties such that actual results and performance may differ
