CACI Appoints Zalmai Azmi as Senior Vice President, Strategic Law Enforcement and National Security Programs

Former FBI Chief Information Officer Led Bureau's IT Modernization Program

Arlington, VA, November 17, 2008 - CACI International Inc (NYSE:CAI) announced today that it has appointed Zalmai Azmi, former Chief Information Officer for the Federal Bureau of Investigation (FBI), as Senior Vice President for Strategic Law Enforcement and National Security Programs. Mr. Azmi joins CACI after leading the development and modernization of the FBI's information technology (IT) program for the past five years. In his new role, Mr. Azmi will leverage his unique federal IT and national security expertise to help grow CACI's name recognition, thought leadership role, and related market share in the law enforcement and national security arena, and assist in the identification of acquisition candidates and initiatives to support the company's growth.

After coming to the FBI in 2003 and being named Chief Information Officer in 2004, Mr. Azmi guided the bureau through its largest-ever technology upgrade. This included the development of the FBI's next-generation information and case management system, and the creation of a knowledge base and assets that enable the FBI to participate fully in information-sharing programs within the intelligence and law enforcement communities, as well as to acquire and adopt commercial best practices.

Prior to the FBI, Mr. Azmi served as Chief Information Officer for the Executive Office for the United States Attorneys. Here, Mr. Azmi developed and implemented a long-term strategic technology plan and created the organization's first information systems security office. Moreover, he was detailed to an intelligence agency and twice deployed to Afghanistan in support of military operations on the ground. Mr. Azmi also served in the United States Marine Corps.

Mr. Azmi has also recently been appointed to the Board of Directors of the InfraGard National Members Alliance. InfraGard is a public-private alliance between the FBI and the 27,000-plus FBI-vetted volunteer members who are the owners and operators of the country's critical infrastructure.

"I am pleased and excited to join CACI," Mr. Azmi said. "CACI has an outstanding reputation and record of support as a provider of valuable, high-quality services and solutions for national security. I look forward to contributing to the growth of CACI's capabilities in strategic law enforcement and national security while continuing to support our country's national security objectives."

CACI President and Chief Executive Officer Paul Cofoni said, "We are proud to have Zalmai Azmi on our team. He brings exceptional experience at the nexus of law enforcement, security, and intelligence that CACI is focused on as part of our strategic growth plan, and he offers hands-on, senior-level expertise in the critical areas of networks and cyber security. His appointment is a key element in CACI's corporate commitment to helping our clients defeat the threat of global terrorism."
