CACI Rejects Lawsuit as Slanderous and Malicious
Frivolous suit based on false statements, conjecture and speculation

Arlington, VA, June 10, 2004 CACI International Inc (NYSE:CAI) today issued the following statement: Yesterday, a New York-based human rights activist group filed a lawsuit in San Diego federal court. The suit accuses CACI, Titan Corporation of San Diego, and several named individuals of conspiring with the U.S. government to carry out various crimes against detainees at detention centers in Iraq.

CACI rejects and denies the allegations of the suit as being a malicious recitation of false statements and intentional distortions. CACI does not have and has never had any agreement with Titan Corporation or anyone else pertaining to conspiring with the government, or to perpetrate abuses of any kind on anyone. CACI has never entered into a conspiracy with the government, or anyone else, to perpetrate abuses of any kind.

The suit alleges a plethora of heinous acts that the company rejects and denies in their totality.

The company has not, nor have any of its employees, been charged with any wrongdoing or illegal acts relating to any work in Iraq. The lawsuit filed against CACI falsely alleges that CACI had contracts for interrogation work in Guantanamo Bay, Cuba. Similarly, named defendant John Israel is not, and has never been, an employee of CACI. These falsehoods and inaccuracies simply demonstrate the utter lack of investigation prior to filing suit by the entities ultimately behind this lawsuit.

The company has stated repeatedly that it will not condone, tolerate or endorse any illegal behavior at any time. The company will act forcefully and promptly if evidence is discovered showing that its employees acted in violation of the law or of CACI's policies. At the same time, the company will not rush to judgment on the basis of slander, distortion, false claims, partial reports, or any incomplete investigations. The company supports the concepts of the rule of law, due process, and the presumption of innocence.

In light of the frivolous and malicious nature of this lawsuit, as well as the apparent lack of any pre-filing investigation of the facts, the company stated it is examining its options for sanctions against the lawyers who participated in the filing of this lawsuit.
