Jun 29, 2004, 01:00 ET from Sun Microsystems, Inc.

/PRNewswire-FirstCall/ -- Sun Microsystems, Inc. (Nasdaq:   SUNW) today
 announced that Allied Irish Bank (AIB), one of Ireland's largest banking and
 financial services organizations, a significant private sector employer and
 one of Europe's largest indigenous companies, will migrate 7,500 desktop users
 and transition branch dependent applications across its entire branch network
 to the Sun Java(TM) Desktop System.
     This agreement, in collaboration with Horizon Open Systems, represents the
 largest financial services enterprise deal for the Java Desktop System, a
 comprehensive, secure and highly affordable desktop solution, since its
 availability in December 2003.
     AIB branch staff in the Republic of Ireland, Northern Ireland and the
 United Kingdom will transition to the Java Desktop System during 2005 as part
 of the rollout by AIB of its New Branch Banking Platform (NBP). AIB chose the
 Java Desktop System for its integrated client environment based on open source
 components and industry standards. In addition, Sun's Services organization
 will provide technology consulting, support and education services to
 complement the Java Desktop System implementation.
     "The global momentum for the Java Desktop System continues at a rapid pace
 because of its affordability, enhanced security and manageability, and
 interoperability," said Curtis Sasaki, vice president, Desktop Solutions at
 Sun. "We are very pleased to have AIB as a client of Sun and see growing
 demand in the financial, education and government markets. With Java Desktop
 System Release 2, the enhanced manageability enables CIOs fine grain
 configuration and access to the desktops."
     Sun has seen an unprecedented worldwide increase in demand for alternative
 desktop technologies. The Java Desktop System has seen tremendous momentum,
 including recent government agreements with the People's Republic of China and
 the United Kingdom, and is now available on Microtel PCs from the world's
 largest retailer. Sun's StarOffice productivity suite, a key component of the
 Java Desktop System, is also gaining increased momentum in the worldwide
 retail space with two million copies sold by German partner, Markement, and a
 multimillion dollar deal with 

SOURCENEXT Corporation, a leading Japanese computer products distributor, to provide the Japanese version of StarOffice(TM) software, StarSuite 7, to 25,000 retail locations in Japan and via Internet downloads. In addition, StarOffice software is migrating thousands of users in India where Sun has reached a landmark agreement with the Indian state government of Haryana and secured a 10,000-seat win with the United India Insurance Company. And with over 1,500 developers signed up to certify their applications on Java Desktop System, a wide range of communications, collaboration, entertainment and productivity solutions further the market reach and opportunity worldwide. The Java Desktop System 2, which shipped in May 2004, is designed to lower computing costs and reduce desktop management complexities while providing a familiar and secure environment. Key features of the Java Desktop System include Sun's StarOffice productivity suite, a familiar look and feel and file and printing interoperability. The Java Desktop System is available on Linux and is scheduled to be available on the Solaris(TM) Operating System and on thin-client solutions from Sun. About Sun Microsystems, Inc.
