ACS and UMass Memorial Enter Outsourcing Agreement

FOR IMMEDIATE RELEASE

DALLAS, TEXAS: October 5, 2005 – Affiliated Computer Services, Inc., (NYSE: ACS), a premier provider of business process outsourcing and information technology solutions, announced today that effective November 1, 2005, it will move from a subcontractor to primary contractor role in providing network, data center, and telecommunications services to UMass Memorial Health Care, Inc., (UMMHC). ACS will also assume responsibility for UMMHC’s desktop support and help desk on January 1, 2006.

UMMHC and the primary contractor, with ACS as its subcontractor, originally entered into a seven-year, $102 million information technology (IT) outsourcing agreement in May 2002. The primary contractor provided applications, help desk, and desktop services and ACS provided the data center, network, telecommunications, and disaster recovery services. By mutual agreement, the outsourcing agreement between UMMHC and the primary contractor will terminate on November 1. UMMHC will take over responsibilities for its applications and project management office, and outsource to ACS the desktop support and help desk services on January 1, following a transition period.

In addition to moving into the primary outsourcing contractor role, ACS retains responsibility for the data center, network, and telecommunications services, while taking on responsibility for help desk and desktop services. Under the new contract, ACS’ revenue will increase by approximately 60 percent.

The new agreement calls for ACS to support 9,000 desktops and peripherals for a population of 12,000 end-users and to furnish 24 x 7 help desk services through its healthcare-dedicated network monitoring and call center in addition to continuing to provide data center, network, telecommunications, and disaster recovery services

“We are confident that ACS, in its expanded role, can make a more important contribution to helping UMMHC achieve its strategic goals through excellence in information technology,” said Wendy Warring, Executive Vice President of UMMHC. “Powerful, agile, and cost effective IT systems are an important element in the success of an academic medical center and critical in enabling us to serve our patients. We look forward to working closely with ACS to support UMMHC’s commitment to excellence in patient care.”

“We appreciate the trust that UMass Memorial Health Care places in ACS as we enter this expanded information technology outsourcing agreement,” said Charles O. Bracken, Managing Director of ACS Healthcare Solutions. “We look forward to applying our extensive healthcare knowledge and recognized expertise in IT services management to achieve UMMHC’s goals.”
