CSC's CFO to Leave After Transition Period

EL SEGUNDO, Calif., Jan. 31 --Computer Sciences Corporation (NYSE: CSC) today announced that Michael E. Keane, the company's vice president and chief financial officer, has resigned as chief financial officer, but will remain a vice president during a transition period. CSC's board of directors has appointed Donald G. DeBuck, the company's vice president and controller, to act as interim chief financial officer while CSC conducts a search to replace Keane.

CSC recently announced that its corporate headquarters will move from El Segundo, California, to Falls Church, Virginia. “After carefully considering the company’s upcoming move of its corporate headquarters and my alternatives, I have decided not to relocate,” said Keane.

Keane, 52, joined the company as vice president, finance, in 2005, and shortly thereafter was promoted to vice president and chief financial officer. Previously, he was senior vice president and chief financial officer at Unova, Inc., an industrial technology company.

During his tenure as CSC's chief financial officer, Keane was involved in a major restructuring, a stock buy back program, a number of major acquisitions and the launch of the company’s new strategic initiative.

Mike Laphen, CSC’s chairman, president and chief executive officer, said, “I understand Mike not wishing to relocate to the Falls Church area. These are very personal decisions. I wish him all the best in his future endeavors."
