CACI Awarded New $34 Million Prime Contract to Continue Support for U.S. Army Intelligence Database

Company Had Been Subcontractor on Facilities Support Program

Arlington, VA, July 7, 2009 - CACI International Inc (NYSE:CACI) announced today that it has been awarded a new $34 million prime contract to continue supporting a classified U.S. Army intelligence database that is part of the Facilities, Infrastructure, and Engineering Systems (FIRES) program. CACI had previously served as subcontractor on this effort but has now been awarded the prime position as a result of the contract being recompeted.

Under the terms of the four-year award (one base year and three option years), CACI's role will increase in size and scope. The company will continue to provide its current technical support, expand this support to new areas, and provide additional management oversight. With the award, CACI continues to grow its core competency in data, information, and knowledge management.

CACI's support for FIRES includes acquiring, under direction of the Army, information on selected facilities and complexes, then digitizing and loading this information into the database. The company's continuing lifecycle support includes database design, development, integration, and maintenance. In addition, CACI is now providing three-dimensional renderings of blueprints and architectural drawings that enhance the Army's ability to ensure comprehensive facilities support and protection. And as prime, the company provides management support that assures the timely and effective completion of goals and projects.

Bill Fairl, CACI President of U.S. Operations, said "We look forward to leading this effort while continuing to deliver cutting-edge technical support. Our team's constant technical and management innovation, mission dedication, and attention to quality are helping Army Intelligence complete its vital missions."

Paul Cofoni, CACI President and Chief Executive Officer, said, "CACI's ongoing strategy is to continually enhance the value and quality of the service we provide to all our clients. Our advance from subcontractor to prime on this effort is a great example of our strategy's success. At the same time, it fulfills our mission of providing the very best support for our nation's highest priorities in intelligence and national security."
