Arlington, VA, November 5, 2004 CACI International Inc (NYSE:CAI) announced today that Chairman, President, and Chief Executive Officer Dr. J.P. (Jack) London has been named Arlington, Virginia's Technology Executive of the Year. Home to a number of top-tier information technology (IT) firms, Arlington is part of Virginia's growing "IT corridor" of innovative technology organizations. The Arlington Chamber of Commerce presents the Technology Executive of the Year award to a business leader who has succeeded in his or her industry and had a distinct positive influence on the market and the region. The award describes the winner as "an entrepreneur in the IT industry who has exhibited a focused vision along with tremendous strength and perseverance." The award was announced on November 4 at the Sheraton National Hotel in Arlington.

The Technology Executive of the Year award recognizes Dr. London's contributions to both the federal government and the city of Arlington. Under his direction, CACI is fulfilling its commitment to the U.S. military, remaining steadfast throughout the war on terrorism. The company also fields and supports intelligence efforts with cutting-edge solutions for the members of America's national defense and intelligence community. At the same time, London's aggressive mergers and acquisition program brought eight of CACI's last 10 purchases to Arlington.

Dr. London is vigilant in his search for innovation and excellence. He transitioned CACI from a small professional services firm of the 1980s into a trend-setting IT and network solutions provider for the millennium. Known for his vision and unique ability to interpret the impact of current trend lines on tomorrow's marketplace, London accurately forecast the rapid change in IT markets. Revolutionizing information systems, logistics sciences, and communications prepared CACI and its clients for the present-day era of asymmetrical warfare. Throughout, London has also continued to uphold CACI's reputation for honesty and ethics, quality client service, and technical distinction.

"I accept this award on behalf of all the employees of CACI," London said. "Their excellence in support of our strategic goals makes it possible for us to continue meeting client and market needs. As our company surpasses $1 billion in revenue and reaches the 10,000-employee mark, the CACI workforce remains the bedrock of our success.
