CACI Awarded $48 Million Contract to Continue Readiness Based Sparing Support for Naval Supply Systems Command

Company Continues History of Helping U.S. Navy Stay Supplied and Ready

Arlington, VA, April 23, 2007 - CACI International Inc (NYSE:CAI) announced today that it has been awarded an indefinite delivery/indefinite quantity contract (one-year base term and four one-year options) to provide technical and engineering support services to the Naval Supply Systems Command (NAVSUP) Readiness Based Sparing (RBS) Program. The base year has a potential value of $9 million; if all options are exercised, the total estimated value of the contract is $48 million. The award continues a series of RBS-related contracts sustaining CACI support for logistics and engineering solutions that keep the U.S. Navy and other customers supplied and ready at all times.

CACI's RBS solutions include business processes, management techniques, and information systems expressly designed to help NAVSUP contain inventory costs while still effectively supplying worldwide military operations. CACI's history of support includes serving early initiatives to model and simulate supply chains, through today's client/server and workstation solutions providing RBS breakthroughs.

Today CACI is helping the Navy lead the way in RBS implementation within the Department of Defense, and is supporting the integration of RBS tools into the Navy's emerging Enterprise Resource Planning (ERP) environment. The company has worked closely with the Navy to develop and implement state-of-the-art sparing models, tools, and techniques, and has led the innovative Naval Logistics Readiness Research Center (NLRRC) combining the efforts of government, commercial, and academic entities to develop and investigate new tools and techniques in RBS. CACI's efforts have resulted in more than $470 million in documented inventory reductions. Most importantly, these reductions were accomplished without compromising the readiness of critical defense assets.

According to Paul Cofoni, CACI's President of U.S. Operations, "CACI offers the Naval Supply Systems Command innovative solutions in Readiness Based Sparing across a wide range of functional areas. The end result is that the U.S. Navy is able to sustain high levels of readiness for key equipment and systems while reducing the cost to taxpayers."

Dr. J.P. (Jack) London, CACI Chairman, President, and CEO, said "CACI is very proud of our legacy of support in helping the U.S. Navy make certain that American troops are the best equipped in the world, ensuring their safety and protection. This latest contract award recognizes CACI's ongoing ability to bring value to our clients' operations with trusted, high-quality solutions in support of their critical missions."
