CACI Awarded $47 Million Contract to Support Center for Excellence in Disaster Management and Humanitarian Assistance

Continues Company's Ongoing Leadership in Supporting Smart Power

Arlington, VA, September 10, 2009 - CACI International Inc (NYSE:CACI) announced today it has been awarded a prime contract with a ceiling value of $47 million, if all options are exercised, to support the Center for Excellence in Disaster Management and Humanitarian Assistance (COE-DMHA). The award, for one base year and four option years, continues CACI's work in supporting the COE-DMHA's mission of educating, training, conducting research, and assisting in responding to natural and manmade disasters in the Asia Pacific Region. The effort is closely integrated with CACI's capabilities in smart power – the integration of the "soft power" of development and diplomacy with the "hard power" of military strength.

The COE-DMHA enhances civil-military and interagency coordination through the research and development of concepts that educate and train partner nations in international disaster management and humanitarian assistance operations. The Center seeks contract services to establish and sustain partnerships with such U.S. and international partners as USAID and its Office of Foreign Disaster Assistance, the United Nations Office for the Coordination of Humanitarian Affairs, and Department of Defense and civilian organizations such as CACI. CACI has worked with COE-DMHA in relief efforts ranging from support during the 2004 Indonesia tsunami, to the 2005 earthquake in Pakistan and the 2006 mudslide in the Philippines.

For this contract, CACI will support the COE-DMHA in a wide array of efforts, including research and concept development; education projects; training; international disaster preparedness, mitigation, management, and response; humanitarian assistance; and management of the consequences of terrorism.

Bill Fairl, CACI's President of U.S. Operations, said "We are proud that CACI is able to continue its role in supporting the efforts of the Center for Excellence in Disaster Management and Humanitarian Assistance. The work we provide goes beyond aiding nations in the Asia Pacific Region – it helps establish the true picture of America as a caring country, deeply involved in world affairs."

According to CACI President and CEO Paul Cofoni, "Finding the right balance between hard and soft power is integral to the use of smart power and all the positive benefits derived from its application. We're pleased that the support CACI provides to COE-DMHA through this award is such an important component in helping our customers focus on how America presents itself to the rest of the world."
