CACI Receives Contract Extension for U.S. Army Interrogation Support in Iraq
Contract Continues CACI's Ongoing Mission-Essential Interrogation and Intelligence Support Services

Arlington, VA, August 10, 2004 CACI International Inc (NYSE:CAI) announced the award of a contract to extend its interrogation services to the U.S. Army in Iraq (interrogation services are an intelligence information gathering function and personnel interview activity). In a statement the company said, "We are pleased to be asked by the Army to continue our work to support the Army's mission in Iraq. Continuity and on-site experience are critical factors to the success of any mission, and the men and women of CACI are proud to have the opportunity to continue to support the ongoing work of the U.S. Army."

The contract, for a period of four months, is worth $15.3 million, and has two optional extensions worth up to $3.8 million each, for a total value of $23 million. CACI noted that the contract was issued directly by the Army and not through any other government organization. The interrogation support services will continue to be provided under the direction of the U.S. military in Iraq.

"We have a long and proud history of serving the U.S. military, and we are pleased once again to answer the call to assist our military's mission around the world," commented CACI Chairman, President, and CEO Dr. J.P. (Jack) London. He concluded saying, "We have been criticized by some for our providing interrogation services at the request of the U.S. Army, but we have been resolute in our position that in war time we should respond when called. The interrogation of detainees, as part of overall intelligence information gathering, is essential to protecting our troops, saving lives and successfully completing the military mission. We will continue to serve our customer as they request, and we are proud to do so in an honorable manner."

CACI has supplied interrogators to supplement the military's interrogation process and activities in Iraq since August 2003. Although CACI estimates that its interrogator staff comprises only a portion of the total interrogation activity around the region, the company is proud to be a part of this vital work. CACI does not provide interrogation support work in locations other than in Iraq.
