New Sony Pictures Mobile Games Highlight Site's Dramatic Early Success in Showcasing Wide Range of Content to Consumers; About 19 Million Users from 190 Countries Have Initiated Free Java Software Download in 120 Days

SANTA CLARA, Calif. -- October 14, 2003 -- Sun Microsystems, Inc. (NASDAQ:SUNW), the creator and leading advocate of Java technology, today announced that java.com has established itself as the leading consumer destination for Java technology content, with a focus on mobile devices. Today java.com is showcasing content including games and entertainment from companies such as Sony Pictures Mobile, Sega, Sorrent (maker of FOX Sports Football and FOX Sports Basketball) and personal productivity tools maker like the Piranha Pricecheck product from mpowers LLC.

"We launched java.com to be the ultimate consumer resource for Java technology consumers," said Ingrid Van Den Hoogen, senior director, Java and Software Strategic Marketing, Sun Microsystems. "The tremendous success of the site is clear and this is just the beginning. The new gaming content from Sony is a good example of how java.com will continue to improve and expand to offer the most compelling Java content available to every consumer, everywhere."

java.com provides consumers with a single place to find all the information they need on Java technology. It is the only site in the industry where consumers can download a free Java Runtime Environment for the desktop with support for Solaris Operating System(OS), Windows, Linux and Mac desktops, and it is the leading site dedicated to Java consumers. Third parties working with java.com have quickly found it a very successful way to reach Java technology consumers.

"At Nextel we're very excited about our presence on java.com. By partnering with Sun and leveraging Java technology, Nextel is able to deliver powerful business applications that improve our customers' operational efficiency and drive incremental revenue," said Ernie Cormier, vice president, Business Solutions, Nextel Communications.

"We have received more hits for our FOX Sports Football game from java.com than any other site on the Web," said Alex Galvagni, CTO of wireless game developer and publisher Sorrent. "It is clear to us that java.com has fast become the favorite site of Java technology consumers in search of the newest, most compelling Java content."

"java.com provides us with an excellent vehicle with which to reach consumers with our free Piranha Pricecheck product," said Michael Powers, principal, mpowers LLC. "With a Java technology-powered phone and our award-winning Piranha Pricecheck, consumers can view the entire Amazon.com catalog to find the best deal fast."

"Tira Wireless' NHL(R) PowerShot Hockey is a prime example of the high entertainment value of the mobile games and applications featured on java.com," said Chris Erickson, CEO of Tira Wireless. "The association between java.com and consumer brands such as the NHL has been a great way to increase consumer awareness of how Java-enabled mobile phones are changing the way people live, work and play. The substantial increase in traffic to www.NHLpowershothockey.com proves the value of this association."
