New Directors Bring Exceptional Leadership and History of Distinguished National Service

Arlington, Va., July 1, 2009 - CACI International Inc (NYSE: CACI) announced today that it has appointed The Honorable James S. Gilmore III, former Governor of Virginia, and General William Scott Wallace, USA (Ret.), former Commanding General of the U.S. Army Training and Doctrine Command, to CACI's Board of Directors. The new directors bring an exceptional history of leadership and distinguished service to the nation, offering unique expertise that will provide strong support for CACI's business.

During his term as Virginia's executive leader, from 1998 to 2002, Governor Gilmore created the nation's first secretariat of technology, established a statewide technology commission, and signed into law the nation's first comprehensive state Internet policy. He also chaired the U.S. Congressional Advisory Panel to Assess Domestic Response Capabilities Involving Terrorism and Weapons of Mass Destruction, a national panel established by Congress to assess federal, state, and local government capabilities to respond to the consequences of a terrorist attack. Also known as the "Gilmore Commission," this panel was influential in developing the Office of Homeland Security. In 2003, President George W. Bush appointed him to the Air Force Academy Board of Visitors, and he was elected Chairman of the Air Force Board in the fall of 2003. Governor Gilmore was also Virginia's Attorney General from 1993 to 1997. His military career includes service as a U.S. Army counterintelligence agent in West Germany from 1971 to 1974. Governor Gilmore is a 1971 graduate of the University of Virginia and a 1977 graduate of the University of Virginia School of Law.

Governor Gilmore's board experience includes serving as Chairman of the Board of Everquest Financial Ltd. He is currently a member of the boards of directors of Atlas Air Worldwide Holdings, Inc. and Cypress Communications, Inc. and served on the board of Barr Pharmaceuticals from 2002 to 2008, and IDT Corporation from 2002 to 2006. From 2002 to 2008, Governor Gilmore was a partner at the law firm of Kelley Drye and Warren, where he chaired the firm's Homeland Security Practice Group and focused on corporate, technology, information technology and international matters.

General Wallace is a visionary senior executive, leader, and organizational manager with a 39-year record of military excellence and achievement. As Commander of the Army's Training and Doctrine Command from 2005 to 2008, he led more than 50,000 soldiers and civilian employees at 33 army schools. He was the architect of the Army's reorganization in the continuation of military operations in Iraq and Afghanistan, and developed the organizational, technical, and warfighting requirements for the Future Combat Systems and other Army modernization efforts.

Prior to this, General Wallace was Commanding General of the Army Combined Arms Center from 2003 to 2005, Ft. Leavenworth, Kansas, where he was responsible for the development of new and emerging Army and Joint doctrine, providing the intellectual foundation for military leadership in the 21st Century.

As Commander of the Fifth U.S. Corps from 2001 to 2003, during the opening campaign of Operation Iraqi Freedom General Wallace led 140,000 soldiers from Kuwait to Baghdad, and subsequently directed the occupation of Western and Northern Iraq. He served as Commander of the Joint Warfighting Center from 1999 to 2001; Commanding General of the 4th Infantry Division - the Army's first "digitized" division that incorporated new C4ISR technologies - from 1997 to 1999; and Commanding General of the National Training Center from 1995 to 1997. General Wallace is a 1969 graduate of the United States Military Academy at West Point. Dr. J.P.
