Fairfax, Virginia, February 3, 2008

CGI Federal, Inc., a wholly-owned U.S. operating subsidiary of CGI Group Inc.,
(NYSE: GIB; TSX: GIB.A) today announced that the U.S. Department of Health and
Human Services, Centers for Medicare & Medicaid Services (CMS) has chosen
CGI to implement CMS’ Provider Enrollment Chain and Ownership System (PECOS)
One-Stop-Shop release. The two year effort, valued at approximately $27 million,
will significantly enhance PECOS and enable state governments to voluntarily
adopt it as the Medicaid enrollment system for all providers and suppliers.
PECOS is already the established system of record for Medicare providers and
suppliers.

One-Stop-Shop represents the first information technology
initiative to process Medicare and Medicaid business transactions at the
national level since Medicare’s and Medicaid’s inception in 1965. In conjunction
with the states, One-Stop-Shop will create a consolidated provider enrollment
form to establish a common basis for much of the data collected while at the
same time providing the flexibility, if necessary, to support state specific
data that can be seamlessly integrated into the system. “While time and money
will be saved as a result of increased operational efficiency, a major value to
CMS, the states, providers/suppliers and US taxpayers will be a reduction in
Medicare and Medicaid fraud and abuse,” said Dave Collignon, Vice-President,
Public Sector Health, CGI.

“CMS has been a customer of CGI since 1998
and we are pleased that they are continuing to partner with us to help improve
Medicare and Medicaid program efficiency,” said George Schindler, President, CGI
Federal. “CGI brings its healthcare program expertise at both the national and
state level to this important effort. CGI’s business is satisfying clients and
this opportunity is an affirmation of the quality of work that CGI delivers to
CMS. We look forward to continuing to support CMS through One-Stop-Shop and our
other initiatives.”
