CACI Awarded $29 Million Contract to Support Network Infrastructure Upgrade for U.S. Marine Corps

Company to Provide Turnkey Services for Microwave Relay Towers to Enhance Training

Arlington, VA, November 3, 2008 - CACI International Inc (NYSE:CAI) announced today that it has been awarded a task order with a ceiling value of $29 million (one five-month base period, with optional contract line items for additional towers and support structures, as authorized) by the U.S. Marine Corps under the U.S. General Services Administration's CONNECTIONS contract vehicle. This new work involves initially providing wide area network infrastructure design, fabrication, installation, and validation of five microwave relay towers for the Naval Surface Warfare Center's Marine Air Ground Task Force Training Command. The award enables CACI to continue building on its role in Marine Corps support and expands the company's capabilities in the critical areas of integrated, enterprise-wide, Command, Control, Communications, Computers, Intelligence, Surveillance and Reconnaissance (C4ISR) programs, as well as information technology infrastructure design and development.

Under the terms of the contract, CACI will erect the five newly-designed, 90-foot high, multi-decked, steel and composite microwave towers on mountain-top sites near the Marine Corps Air Ground Combat Center, on remote, inaccessible areas of California's Twenty-nine Palms military reservation. Heavy-lift and passenger helicopters will be used to haul all the steel components – as well as the excavation and earth moving machinery, the communications equipment, and the personnel – required to build and service these solar-powered installations. Once completed, the towers will serve a vital role in supporting the Marine Corps in training warfighters to complete their missions more efficiently through enhanced communications.

As developed by CACI and its partners, the innovative design of the towers incorporates state-of-the-art technologies, manufacturing techniques, and installation approaches that reduce the total cost of ownership and minimize structural and support risk during installation and for the operational life of the structures. The design offers great potential for re-use in other Department of Defense and federal civilian agency applications beyond this contract.

According to Bill Fairl, CACI's President of U.S. Operations, "This CONNECTIONS contract with the U.S. Marine Corps demonstrates CACI's broad capabilities as a leading systems integrator. Our ability to assemble an expert team to tackle difficult design, manufacturing, and logistics issues was a key factor to our success."

CACI President and CEO Paul Cofoni said, "This new work is specifically geared to providing the Marines with improved training skill-sets through advance communications. We're proud that in helping them advance their warfighting capabilities, we are also enhancing CACI's role in countering global terrorism."
