Solutions

ARLINGTON, Va., Aug. 27 /PRNewswire-FirstCall/ -- The Wexford Group
International, a wholly owned company of CACI International Inc (NYSE: CACI),
announced today that the company has been awarded a five-year prime contract
to continue its support for the Joint Improvised Explosive Device Defeat
Organization (JIEDDO). This is one of five awards for this indefinite
delivery/indefinite quantity contract, which has a ceiling value of
approximately $494 million. The contract expands the company's existing
business with JIEDDO and enhances CACI's position as one of the premier
counter-IED companies in the world. The award strengthens CACI's functional
core competency in integrated security and intelligence solutions and
leverages Wexford as a centerpiece of that core competency.

JIEDDO leads the Department of Defense efforts in countering improvised
explosive devices (IEDs), via a three-pronged strategy for defeating IEDs:
attack the network, defeat the device, and train the force. JIEDDO integrates
DoD's efforts with all Combatant Commands, the Armed Services, the
Intelligence Community, interagency organizations, and public, private and
international partners.

With this contract, CACI-Wexford, Inc. will support JIEDDO with strategic
planning, operational and training support, intelligence analysis, program
management support, and strategic communications. The company's ability to
deliver expert training, assessment, and analysis helps assure mission goals
are met successfully, effectively, and on time. Wexford has been working with
JIEDDO and its predecessors since November 2003.

Bill Fairl, CACI President of U.S. Operations, said, "This work with the Joint
Improvised Explosive Device Defeat Organization offers CACI an exceptional
opportunity to continue our significant support for this critically important
Department of Defense organization. We're extremely proud of our employees who
help JIEDDO accomplish its mission of defeating threats to our nation's
service members serving in harm's way."

According to Paul Cofoni, CACI President and Chief Executive Officer, "We are
very pleased that the Wexford Group International can, once again, make a
vital contribution to helping JIEDDO safeguard our warfighters. This is a
significant contract that further solidifies CACI's government partnership
through which we provide high-quality, leading edge services in support of the
nation's defense."
