CACI Appoints Vice Admiral Albert Calland, USN (Ret.) as Executive Vice President for Security and Intelligence Integration

Former Deputy Director of National Counterterrorism Center and Central Intelligence Agency, Commander of Special Operations, to Support CACI National Security-related Business Areas

Arlington, VA, August 13, 2007 - CACI International Inc (NYSE:CAI) announced today that it has appointed retired U.S. Navy Vice Admiral Albert M. "Bert" Calland III as Executive Vice President for Security and Intelligence Integration. Mr. Calland most recently served as Deputy Director for Strategic Operational Planning at the National Counterterrorism Center (NCTC). Prior to that he was Deputy Director of the Central Intelligence Agency (CIA) and served as Commander of Special Operations Central within the U.S. Central Command (CENTCOM). Mr. Calland will support CACI's continually expanding business within well-funded markets in the Intelligence Community and the growing market for information sharing at the nexus of intelligence, defense, and law enforcement capabilities that is so critical to our nation's defense.

A highly decorated veteran, Mr. Calland brings battlefield leadership and command experience at all levels. His 33-year Navy career included service as a platoon commander with the Navy's Sea, Air and Land (SEAL) special operations forces through command of the Navy Special Warfare Development Group from 1997 to 1999.

In 2000, Mr. Calland assumed command of CENTCOM's Special Operations Command. Following the September 11 terrorist attacks, he transitioned his headquarters into a forward-deployed Joint Forces Special Operations Component Command, directing more than 3,000 U.S. and Coalition Special Operations Forces in Operation Enduring Freedom. In this role, Mr. Calland was the first U.S. military flag officer in Afghanistan.

After serving as Commander of the Naval Special Warfare Command from 2002 until 2004, Mr. Calland was assigned as the CIA's Associate Director of Central Intelligence for Military Support and was subsequently appointed the CIA's Deputy Director (the Agency's second highest position) in 2005. In 2006, Mr. Calland was assigned to NCTC, the federal government's primary organization for integrating and analyzing intelligence on terrorism and conducting strategic operational planning across multiple agencies and organizations. At the CIA and at NCTC, Mr. Calland worked on the most difficult national security issues at the highest levels in our government.

"I look forward to joining CACI and continuing to improve our country's national security capabilities," Mr. Calland said. "CACI has an outstanding reputation and a strong commitment to its customers' missions. I'm excited about helping CACI grow its business and enhance its solutions for the vitally important intersection of intelligence, homeland security, and law enforcement."

CACI President and Chief Executive Officer Paul Cofoni said, "Vice Admiral Albert Calland is a special operations professional of extraordinary experience and expertise. He is also an accomplished intelligence expert. He has led troops in battle and worked at the highest levels of government. He possesses an unmatched understanding of the challenges facing our nation today and the solutions CACI can offer to help meet these challenges. CACI is especially focused on growing our information technology services for the intelligence and national security priorities of our country, and we are extremely proud to welcome him to our team."
