Fairfax, Virginia, September 13, 2011

CGI Federal Inc. (CGI), a wholly-owned U.S. operating subsidiary of CGI Group Inc. (NYSE: GIB) (TSX: GIB.A) has been awarded a task order renewal worth US$207 million over a six year period to support the Environmental Protection Agency’s (EPA) Central Data Exchange (CDX). EPA’s Office of Environmental Information awarded the contract under the GSA Alliant Government-wide Acquisition Contract (GWAC) vehicle.

CDX is one of EPA’s core technology assets, enabling streamlined, electronic collection, sharing, and reporting of environmental data between EPA’s program offices and its external stakeholders, including states, tribal nations, and regulated industries. CGI will continue to support CDX through a wide range of technology services, including information assurance/cybersecurity, web application and systems development, program management, user support, and operations and maintenance services.

“The unprecedented budget challenges facing federal agencies will continue to demand that they use technology to increase collaboration across government and with external stakeholders to achieve their goals,” said George Schindler, President, CGI Federal. “With CDX, the EPA has established a government-wide best practice for using IT to support the agency’s mission as well as the day-to-day operations of its program offices.”
