CACI Awarded $62 Million Contract With U.S. Army Quick Reaction and Battle Command Support Division

S3 Award Continues CACI Support for Rapid Prototyping and Technology Insertion

Arlington, VA, August 11, 2008 - CACI International Inc (NYSE:CAI), announced today that it has been awarded a $62 million contract to support the Quick Reaction and Battle Command Support Division of the U.S. Army's Communications-Electronics Research, Development and Engineer Center's Command and Control Directorate (CERDEC C2D) located in Fort Monmouth, N.J. CACI won this three-year competitive award through the Strategic Services Sourcing (S3) contract vehicle the company holds with the Army. The company will support the client's current needs and transition future work on this contract, as required, to CACI's new facilities at the Army's Aberdeen Proving Ground, Md. With the award, CACI continues to strengthen its core competency in command, control, communications, computers, intelligence, surveillance, and reconnaissance (C4ISR).

The Quick Reaction and Battle Command Support Division provides CERDEC C2D with rapid prototyping and fielding of emerging C4ISR and related technology. The division designs, develops, builds, installs, integrates, tests, and fields such systems for all the armed services, for use in shelters, vehicles, aircraft, watercraft, and hand-held operation by troops in the field.

CACI's team provides a wide range of technical services and solutions in support of C2D. This includes engineering support for a U.S. Marine Corps mobile testing and repair facility, and prototyping and technology support for Army mobile command posts. The company and its teammates will develop computer-aided drawing and manufacturing applications that enable the Army to create "virtual" prototypes before committing to development. CACI will also work closely with C2D to identify, prototype, demonstrate, refine and test new C4ISR solutions that have promise for use in broader environments.

For more than 20 years, CACI has supported CERDEC, its commands, and many other Army organizations from offices at and around Ft. Monmouth, N.J. Now, while Army operations transition, CACI is able to provide additional support for CERDEC and other Army clients.

CACI President of U.S. Operations Bill Fairl said, "CACI brings a great track record to our support for the Quick Reaction and Battle Command Support Division. Our team's deep functional understanding of the division's highly complex and unique engineering efforts ensures minimal risk and high-quality technical support for this important client."

Paul Cofoni, CACI President and Chief Executive Officer, stated, "CACI continues to serve our clients wherever and whenever we are needed. We are proud of our work for commands at Fort Monmouth that deliver critical intelligence, engineering, and logistics services for our warfighters, and we are dedicated to providing tools and resources to support the seamless transition of these vital operations to their new home at the Army's Aberdeen Proving Ground."
