Pursuant to Rule 14a-12 under the Securities Exchange Act of 1934

Subject Company: Sun Microsystems, Inc.

Commission File No.: 000-15086


On April 20, 2009, Oracle announced a definitive agreement to acquire Sun Microsystems. The proposed transaction is subject to Sun stockholder approval, certain regulatory approvals and customary closing conditions. Until the deal closes, each company will continue to operate independently and it is business as usual.

This proposed acquisition will combine best-in-class enterprise software and mission-critical computing systems. Oracle plans to engineer and deliver an integrated system – applications to disk – where all pieces fit and work together so customers do not have to do it themselves. Customers are expected to benefit as their systems integration costs go down while system performance, reliability, and security go up.

Sun’s core innovations such as Java, Solaris and SPARC are some of the computer industry’s best known brands and most widely deployed technologies. Oracle Fusion Middleware is built on top of Java and we believe that following the acquisition Oracle will be able to ensure continued innovation and investment in Java technology for the benefit of customers and the Java community.

The Solaris operating system and SPARC servers are the leading platform for the Oracle database. With the proposed acquisition of Sun, we believe Oracle will be able to optimize the Oracle database for some of the unique and innovative features of Solaris. Like Sun, Oracle supports many platforms and also remains committed to Linux and other open platforms and will continue to support and enhance its strong industry partnerships.

After the closing, Oracle and Sun partners are expected to benefit by working with a single vendor to address customer needs for enterprise systems with complementary solutions that provide an opportunity to increase business value and drive down the total cost of ownership through an integrated, standards-based enterprise product stack.

We are dedicated to maintaining and increasing the level of innovation, support and service you have come to expect from Oracle and Sun. To learn more about the acquisition please visit
