CACI Emphasizes Facts Presented During
Congressional Testimony on Iraq Prison Investigation and
Requirements Related to Company's U.S. Military Contract

No information on improper behavior reported to company by U.S. Government;
Company does not tolerate illegal behavior by employees

Arlington, Va., May 9, 2004 - CACI International Inc (NYSE: CAI) today provided an update to ongoing investigations into prison abuse in Iraq in response to Congressional testimony and to clarify information in recent media reporting about its employees. The company continues to support the Army's mission in Iraq and around the world.

Dr. J. P. (Jack) London, CACI Chairman, President and CEO said, "The testimony provided by the Secretary of the Defense, the Secretary of the Army, and the Central Command Deputy Commander have cleared up an important point: As stated, CACI employees are monitored and are under the supervision of U.S. Army personnel. This was exactly as set forth in CACI's services contract with the U.S. Military, and CACI has carried out this role as stated."

In the Senatorial hearing Friday, May 6, 2004, when asked, "What are the roles of contractors and who supervises them", Secretary of Defense, Donald Rumsfeld, replied that "they are responsible to military intelligence who hire them, and have the responsibility for supervising them". Acting Secretary of the Army, Les Brownlee, added, "in the theatre we have employed civilian contract interrogators and linguists. The Central Command has done this. And these people have no supervisory capabilities at all. They work under the supervision of officers in charge or non-commissioned officers in charge of whatever team or unit they are on ..." Central Command Deputy Commander, Lieutenant General Lance Smith, also added, "In this particular case there is a tiger team that interrogates and goes through that process. One is an interpreter normally. One is an analyst. And one is an interrogator. And where we have a shortage in the military of interrogators and translators we go to contractors to do that."

Dr. London also stated that, "there is an ongoing investigation underway in which our people have co align=justifyoperated in the interview process. CACI will continue to cooperate with all U.S. Government investigations when requested and is now conducting its own analysis and investigation of events." London continued, "The numerous allegations, speculations, rumors, interpretations and partial reports, and editorial opinions appearing in the media make the task challenging. It is critical that we determine the facts, and not permit hearsay or unsubstantiated rumors and accusations to unfairly condemn any individual."

None of CACI's employees have been charged with any wrongdoing at this time notwithstanding the allegations appearing in the leaked report of Major General Antonio M. Taguba, which was conducted early on, as one part of an ongoing investigation. London said, we understand the complexities and difficulties of the legal process that the Department of Defense must follow and the company is awaiting an outcome. In the unfortunate event that any CACI employee engaged in an illegal act, either independently or under orders from an Army supervisor, or otherwise suggested, participated in, or ordered illegal acts, the company will take immediate and appropriate action. CACI has not and does not condone, tolerate or endorse any illegal or inappropriate behavior on the part of any employee in any circumstance, at any time, anywhere.

The company referred to erroneous comments reported in the media about the qualifications of CACI personnel serving in Iraq, the level of military supervision over them, and the processes CACI uses to recruit personnel for military support roles.

In response to these allegations and erroneous comments, the company noted the following:

CACI continues to provide interrogators to the U.S. Military who are working under the monitoring and supervision of military personnel. London said, "The military states they are shorthanded, the war is continuing and interrogation work and intelligence data collection and analysis still needs to be done."

CACI continues to support the U.S. Military's mission in Iraq and around the world and the company has not received any information to stop any work, or otherwise to show cause for any inability to perform under contract. London said, "We are proud of the outstanding work CACI people diligently provide to our valuable customers and we applaud their vigilant dedication to our customers mission."
