CACI Awarded $16 Million Contract to Provide Logistics Analysis and Training Support to U.S. Navy and Marine Corps

Future Value Estimated at $85 Million If All Options Exercised

Arlington, VA, December 20, 2004 — CACI International Inc (NYSE:CAI) announced today that it has been awarded a prime contract by the Fleet and Industrial Supply Center, Norfolk, Detachment Philadelphia, to provide technical services to support the Fleet Assistance and Shipboard Training (FAST) program. The award, which is for one base year with four one-year options, has a current value of $16 million that could increase to $85 million if all options are exercised. CACI will perform the work at various U.S. Navy and Marine Corps facilities stateside, overseas, and on board naval vessels. As the 17-year prime incumbent for these services, CACI continues to demonstrate its expertise in logistics analysis and training. Additionally, the company continues to increase its role in Navy and Marine Corps support, which is a key component of its core engineering and logistics line of work.

The FAST program provides a wide range of support for afloat and deployable automated supply management programs and services for the Navy and Marine Corps. This support consists of on-site assistance, training, and analysis; formal training; database validation, correction, and reconciliation, and inventory reconciliation.

CACI's role is to provide FAST users with comprehensive and innovative logistics, inventory, training, and financial management solutions that help improve automated supply operations and Fleet readiness. The FAST program focuses on program-level, user-level, and other functional solutions that address and resolve supply problems from an applications, systems, and training perspective. To achieve this goal, CACI's solutions apply experience, expertise, tools, and performance monitoring to meet the operational, technical, and programmatic challenges of supporting our Navy's ships, battle groups, aircraft, and Marine Corps aircraft in maintaining optimum readiness at all times. CACI also supports the design, prototyping, and evaluation of new logistics applications and concepts.

Dr. J.P. (Jack) London, CACI Chairman, President, and CEO, said, "CACI's ongoing partnership with the U.S. Navy and Marine Corps demonstrates how we have continually evolved our solutions in support of constantly evolving requirements. CACI's processes for identifying project risks and developing solutions, and its record of successfully implementing solutions for more than 17 years, ensure the Navy and Marine Corps of continued high-quality, low-risk service.
