EL SEGUNDO, Calif., May 21 - Computer Sciences Corporation (NYSE: CSC) today announced that its Board of Directors has elected CSC President and Chief Operating Officer Michael W. Laphen to the position of chief executive officer, effective immediately. Laphen, 56, succeeds Van B. Honeycutt, 62, who will remain as chairman and a CSC employee through his current term, which expires on July 30, 2007. Laphen, who retains the position of president, will become chairman at that time.
“I am honored to be selected as CSC’s next CEO, and I will strive to serve the best interests of CSC’s clients, employees and shareholders in the same way Van has succeeded in doing over his 32 years,” said Laphen. “I would like to add that we owe a great deal of thanks to Van. He led our company through a period of tremendous growth and has laid the foundation for the next level of CSC’s success.”
“Mike is an exceptional leader who understands our industry very well,” said Honeycutt. “I have worked very closely with him, particularly during the past four years while he has been our COO. I am confident he will continue CSC’s great legacy as a global market leader in the information technology services industry.”

named president and chief operating officer in April 2003, he served as the chief executive of CSC’s European Group. Prior to his European assignment, Laphen served as president of the company’s Federal Sector - Civil Group, where he was responsible for all CSC business with U.S. federal government civil agencies. Earlier, as president of CSC’s Integrated Systems Division, he led CSC’s activities in providing large-scale systems integration, systems engineering and software development projects to the aerospace and defense markets.
Laphen has a bachelor’s degree in business from Pennsylvania State University and an MBA degree from the Wharton School of Business at the University of Pennsylvania. He served in the United States Air Force and the Pennsylvania Air National Guard, and is a member of the Information Technology Association of America, the Armed Forces Communications and Electronics Association and National Defense Industrial Association.
Van Honeycutt will retire from his role as CEO after a 32-year career with CSC, but will continue his service to the company in an ongoing consulting role. He was named chief executive officer in 1995 and chairman of the Board of Directors in 1997. Under his leadership, CSC’s revenue grew from $3.4 billion to $14.7 billion, and the market value increased from $2.6 billion to $9.4 billion, as reported for the fiscal quarter ending December 2006. He is widely credited with CSC’s entrance into the information technology (IT) outsourcing business in 1991, which was the principal growth engine of the company throughout the 1990s. He was instrumental in diversifying CSC’s customer base from predominantly U.S. federal clients to commercial and international clientele, and was president of CSC’s Industry Services Group. Additionally, he managed CSC's aggressive strategy of acquisitions, mergers and alliances that has strongly positioned CSC in key vertical markets. In an earlier assignment, Honeycutt transformed a small acquisition into one of the nation’s largest credit reporting organizations.
