Arlington, VA, November 4, 2009 - CACI International Inc (NYSE:CACI) announced today it has been awarded a $75 million task order to continue its support for the Army's Communications-Electronics Research, Development and Engineering Center (CERDEC) Intelligence and Information Warfare Directorate (I2WD) through the Technical Engineering Support Services (TESS) contract. The task order is for a base period of two years with two one-year options and continues more than 21 years of CACI support to I2WD under TESS and prior omnibus service contracts. The award continues and grows the company's business in command, control, communications, computers, intelligence, surveillance and reconnaissance (C4ISR) programs.

In this highly competitive arena, the win further demonstrates our expertise and competence in providing proven solutions to CERDEC and I2WD."

According to CACI President and CEO Paul Cofoni, "We're very proud that the U.S. Army recognizes our outstanding capabilities in delivering tried and tested rapid development engineering processes to help I2WD and our Armed Forces counter global terrorism.
