ACS Wins U.S. Department of Education Common Services for
Borrowers Student Loan Contract

DALLAS, TEXAS: November 20, 2003 — ACS (NYSE: ACS), a premier provider of business process and information technology outsourcing solutions, announced today that it has been selected by the U.S. Department of Education (Department) as the winner of the Common Services for Borrowers (CSB) contract. The CSB contract, signed today, includes comprehensive loan servicing, loan consolidation, and portfolio management services.

The new, 5-year base contract will integrate a number of currently separate services, which will allow the Department to increase service quality while saving overall program costs. The contract is estimated at more than $1 billion dollars in revenue to ACS over the five-year base period. The contract also includes provisions for up to five, one-year extensions, which would increase the potential revenue to $2 billion. The new contract is effective January 1, 2004. ACS reaffirms full-year, fiscal 2004 financial guidance.

Since 1993, ACS has provided complete business process management services including systems development, integration, management, operations, and customer service to the Department of Education’s direct loan program. Under this procurement, the Department will modernize the servicing system and shift the contract to a performance-based arrangement. ACS will provide comprehensive servicing, consolidation, and portfolio management for more than $95 billion in loans to more than nine million student aid borrowers.

In higher education, ACS is a recognized leader in business process outsourcing for colleges and universities, student-aid lenders, and the Department of Education. In response to the Department’s requirements and strategic objectives, ACS recruited and

assembled a group of subcontractors for its winning team. The team includes key partnerships with EDS, Pearson Government Solutions, Raytheon Corporation, and more than 30 small business and minority-owned enterprises.

“The ACS team is excited that the Department of Education has decided to continue our long-standing relationship of delivering excellent service to the Department and the nine million student borrowers,” said Jeff Rich, Chief Executive Officer of ACS. “This contract means a great deal to ACS and our partners and we are thrilled to continue to serve the Department for years to come.”
