CACI Awarded $17 Million Task Order to Provide Infrastructure Support to U.S. Army Reserve

Company to Support Essential Anti-Terrorism and Force Protection Activities

Arlington, VA, November 13, 2006 - CACI International Inc (NYSE:CAI) announced today that it has been awarded a $17 million prime task order by the U.S. Army Reserve Command (USARC) in Fort McPherson, Georgia to provide critical infrastructure assurance services support of U.S. Army Reserve antiterrorism activities worldwide. The four-year award (one base year, three option years) was made under the $650 million, multiple award U.S. Army Forces Command (FORSCOM) Operations, Planning, Training, and Resources Support Services (OPTARSS) contract vehicle announced in March 2003. CACI already supports USARC in a number of other areas and provides similar support to various government agencies. This new task order for the USARC increases CACI's work providing critical infrastructure assurance services and expands the company's business in intelligence solutions.

Under the terms of the task order, CACI's role focuses on assessing critical infrastructure programs and procedures that help pinpoint the USARC's vulnerability to terrorist threats. This includes helping the USARC gauge the effectiveness of antiterrorism initiatives, evaluate antiterrorism programs, review defensive information operations, and provide intelligence analysis.

CACI brings USARC a unique advantage by providing experienced and dedicated employees with extensive client experience. CACI's key personnel collectively exceed 100 years of USARC operational experience and offer deep functional understanding of how to develop doctrine, policies, and protocols for the Army. CACI employees were also instrumental in developing USARC's Defense Information Operation scans, a data storage and retrieval system that the Army awarded "The Most Innovative Antiterrorism Program for 2005."

According to CACI President of U.S. Operations Paul Cofoni, "The U.S. Army Reserve Command task order is one more strong vote of confidence from the Army on the professionalism and expertise that CACI provides in everything we do for the service. CACI's record of providing quality intelligence support personnel, coupled with our growing expertise in antiterrorism and force protection, assures USARC of the effective implementation of its critical programs."

Dr. J.P. (Jack) London, CACI Chairman, President, and CEO, said, "CACI's selection to support this important anti-terrorism award with the U.S. Army Reserve broadens the company's involvement in helping our nation fight the war on terrorism. And it demonstrates the superior levels of experience and expertise our people have in developing intelligence solutions that serve critical defense priorities."
