Fairfax, Virginia, June 2, 2008

CGI Federal, Inc., a wholly-owned U.S. operating subsidiary of CGI Group Inc. (NYSE: GIB; TSX: GIB.A), today announced the release of the first Open Source Node 2.0 software product to be available to EPA data exchange partners on the National Environmental Information Exchange Network (Exchange Network). The CGI Node 2.0 software is offered to Exchange Network partners and other interested members of the environmental community to give them capabilities to publish, share, and gain access to environmental data for improved decision making.

The National Environmental Information Exchange Network includes EPA's Central Data Exchange (CDX), the point of entry for Agency environmental data exchanges. Together, CDX and the Exchange Network partners' nodes are the infrastructure that enable efforts to collect, share and monitor the environmental data used to assess the impact of global warming, monitor the safety of our water supplies, gather geographic information on sources of pollution, and encourage overall excellence in the study and stewardship of our environment.

CGI Node 2.0 represents an expansion of this community to allow sharing across federal, state, commercial and citizen boundaries related to software development and technological innovation. It allows users to collaborate, publish, and discover environmental information and services across disparate systems. The node's dashboard allows for quick and easy reporting, scheduling, and administration capabilities.

"Flexible and rapid data exchange capabilities are critical to responding to environmental challenges faced by government agencies and their trading partners," said Melanie Morris, Chief of Data Integration Division, Mississippi Department of Environmental Quality. "Establishing the building blocks of an Open Source community that supports environmental collaboration and decision making will help stakeholders leverage their investments and capitalize on shared business drivers."

CGI Vice President Kenyon Wells added: "CGI is proud of our long history in helping EPA meet its mission of protecting the environment. Our open source software is the latest example of how CGI invests in the success of its clients and will allow Exchange Network partners to save money while promoting standardization for the sharing of important environmental data."

CGI will be hosting a Webinar to demonstrate the CGI Node 2.0 on June 4th. For more information about this event or about the Node product please refer to the CGI Environmental Practice Website: www.cgi.com/environment.
