CACI Continues to Inform Investment Community and Public at Large About CACI's Business In Iraq
The Company Seeks to Correct Inaccurate Reports

Arlington, VA, June 13, 2004 CACI International Inc (NYSE:CAI) today presented a synopsis of information it has been providing to the investment community and the public about its business in Iraq. For more than 42 years, CACI has proudly provided information technology (IT) services to government and private sector customers to enhance efficiency and meet mission effectiveness. In these four decades the company has successfully provided IT services through seven Presidential administrations of the U.S. government that have had varying policies, agendas and objectives. Throughout its history in contracting with the government, CACI's steadfast objective has always been to support the country's future through quality service.

CACI takes pride in meeting its customers' needs and in achieving the highest ethical standards in so doing. Further, CACI is proud to provide a range of services to help American soldiers and the Department of Defense in Iraq to fulfill their mission. Our advanced information technology solutions and intelligence support services in Iraq enhance military effectiveness and free troops for other critical military missions. For all of these services CACI has received good reports about its performance from its U.S. military customers in Iraq.

While we provide services around the world that support the U.S. government, our work in Iraq recently has drawn attention in relation to interrogation activities at the Abu Ghraib prison near Baghdad. Nonetheless various media and press reports have mistakenly included false, distorted or inaccurate information, which we seek to correct. The following comprehensive summary is provided here; additional information is available on CACI's website www.caci.com .

CACI will continue to cooperate with all involved to address and resolve these issues. Our work for government agencies plays a vital role in protecting Americans' security, improving the performance of domestic programs and enhancing our country's intelligence capabilities at home and abroad. We are proud of that work and will continue to serve our customer, the U.S. government, in the tradition of excellence that has made CACI a truly outstanding organization.
