SANTA CLARA, Calif., Sept. 16, 2005 -- Sun Microsystems Inc. (Nasdaq: SUNW) Chairman and Chief Executive Officer Scott McNealy helped to celebrate 10 years of Java(TM) technology-based innovation and growth at Sun's inaugural JavaChina 2005 Developer Conference this week, and delivered keynote presentations at major customer, developer and partner forums in China, Singapore and Japan.

Sun hosted nearly 10,000 Java platform developers and IT professionals during the two-day event in Beijing, which was broadcast via satellite to eight additional cities throughout China in one of the largest networked developer events of its kind. The Java technology-based developer community in China is one of the fastest growing in the world today, with 216,000 professional Java platform developers, spanning a diverse range of interests from enterprise applications to mobile gaming. This number is expected to reach about 260,000 by year's end.

Globally, Sun estimates the total Java technology-based economy to be more than $100 billion in sales annually driving an additional $110 billion in related IT spending. The global Java technology-based economy includes 4.5 million developers, 1 billion Java Card(TM) systems, 700 million PCs shipped with Java technology, 708 million Java technology-powered phones and over 140 telecommunications carriers who deploy Java technology. James Gosling, widely recognized throughout the world as the 'father of Java technology' and chief technology officer of the Sun developer products group, also spoke at the event.

"The number of Java technology-based devices topped 2.5 billion this year, and as more people gain access to the global network, interaction and innovation can now happen anywhere," said Scott McNealy, Chairman and CEO, Sun Microsystems. "The positive impact of millions of additional connections on economic and social development is as undeniable as the business opportunities created for those who lead the way."

On September 16th in Tokyo, McNealy delivered the keynote address at Japan NC05Q3, an extension of Sun's quarterly global Network Computing product launch event that was held in New York City on September 12, 2005. He was joined on stage by distinguished guest and strategic alliance partner Hector Ruiz, chairman, president and chief executive officer, AMD.

McNealy unveiled Sun's new enterprise-class Sun Fire(TM) x64 (x86, 64-bit) family of servers, which sets new standards for performance, reliability and energy efficiency. Powered by AMD Opteron(TM) processors, the highest- performance x64 processors on the market, and running the Solaris(TM) 10 Operating System (OS), the new industry-standard servers are about one-third the power, one-and-a-half times the performance, and cost half as much as comparably configured 4-way servers from Dell(1). The industry-standard x64 servers can also run standard distributions of the Linux and Windows operating systems. In addition to the range of new systems, the company's quarterly product roll-out also included software and services designed to help customers build smarter, more cost efficient enterprises.

McNealy also met with customers, partners and community leaders in Singapore during his visit to Asia.
