Xerox and ACS Set February 5 for Shareholders Meetings on Acquisition of Affiliated Computer Services

NORWALK, Conn., Dec. 28, 2009 – On February 5, Xerox Corporation (NYSE: XRX) and Affiliated Computer Services, Inc. (NYSE: ACS) shareholders will vote on Xerox’s agreement to purchase ACS, the world’s largest diversified business process outsourcing firm. The joint proxy statement has been finalized and will be sent to Xerox and ACS shareholders. Xerox and ACS boards of directors recommend shareholders vote in favor of the acquisition, which will transform Xerox into the leading global enterprise for document and business process management, accelerating its growth in an expanding market.

In preparation for the shareholder meetings, Xerox and ACS satisfied Hart-Scott Rodino and Securities and Exchange Commission requirements. Earlier this month, Xerox successfully completed a $2 billion capital markets transaction, the net proceeds of which support the ACS acquisition.

On Sept. 28, Xerox announced a definitive agreement to acquire ACS in a cash and stock transaction. ACS is a $6.5 billion company with revenue growth of 6 percent and new business signings of $1 billion in annual recurring revenue during its fiscal 2009.
