Sun Microsystems Announces Internet Availability of Annual Stockholders' Meeting Proxy Materials for Fiscal Year 2008

SANTA CLARA, CALIF. September 24, 2008 Sun Microsystems, Inc. (NASDAQ: JAVA) today announced the Internet availability of proxy materials for its 2008 Annual Meeting of Stockholders under the U.S. Securities and Exchange Commission's Notice and Access rule. Sun's proxy materials can now be found on the Company's investor relations website athttp://www.sun.com/investors.

As an alternative to the traditional approach of delivering a printed set of proxy materials to each stockholder, companies may now deliver a "Notice of Internet Availability of Proxy Materials" to stockholders, provide Internet access to the proxy materials, and provide a printed set of proxy materials by mail upon request. In 2007, Sun was one of the first large accelerated filers (issuers having a market capitalization of $700 million or more) to adopt the rule. Since adopting the rule, Sun was able to reduce the number of printed copies of its proxy materials by nearly 95 percent as compared to the number of proxy materials printed in 2006 - lowering both the cost and the environmental impact of producing and delivering these materials to its stockholders.

Sun's 2008 annual report on Form 10-K and proxy statement have been filed with the SEC, and may be viewed on Sun's website athttp://www.sun.com/investors. Sun's stockholders may obtain printed copies of Sun's proxy materials free of charge by following the instructions provided on the company's website or in the "Notice of Internet Availability of Proxy Materials".

The Sun Microsystems 2008 Annual Meeting of Stockholders will be held on Wednesday, November 5, 2008 at 10:00 a.m. (PST) at Sun's Santa Clara Campus, located at 4030 George Sellon Circle, Santa Clara, California 95054.
