Virginia, Fairfax, November 8, 2006

CGI Group Inc. (NYSE: GIB, TSX: GIB.A), today announced that they have been selected as a strategic technology partner and contributing force to TerreStar Networks Inc.'s architecture that will support the launch of the first all IP-enabled mobile network. TerreStar Networks Inc. is a subsidiary of Motient Corporation (MNCP) and an emerging North American mobile communications operator.

Throughout this multi-phase partnership, CGI will provide TerreStar a broad range of consulting and support services based on its considerable experience with IMS-based (IP Multimedia Subsystem) service delivery. Initially, CGI and TerreStar defined the Operational Support Systems and Business Support Systems (OSS-BSS) architectures and conducted a rigorous evaluation process to create solutions that will bring best-of-breed technology to TerreStar's overall mobile communications service.

"We consider CGI to be our trusted advisor in this multi-phased roll-out of our next generation, all-IP network," said Doug Sobieski, Senior Vice President, Managed Solutions for TerreStar. "CGI's expertise and track record of delivering quality services will support TerreStar's goal to deliver differentiated next generation services faster, better and more efficiently than any other service provider."

As existing service providers and small, medium and large enterprises ramp up 4G networks, they will require an all IP, web services oriented OSS-BSS infrastructure. CGI and TerreStar will jointly develop the business plan to take the OSS-BSS system being developed to the broader market.

"We understand the need of our clients to get to market more efficiently and cost-effectively than their competition," said Nazzic Turner, Senior Vice President of CGI. "CGI is proud to be identified as a strategic technology partner of TerreStar's architecture team. When launched, TerreStar's unique all IP, integrated satellite and cellular technology will enable them to deliver high quality, cost-effective, seamless wireless services to urban, rural and remote regions throughout North America. TerreStar's 4G OSS-BSS has potentially wide ranging applicability to the telecommunications industry, and we intend to work closely with TerreStar to leverage its value on behalf of service providers."
