Montreal, Quebec, September 8, 2008

CGI Group Inc. (TSX: GIB.A; NYSE: GIB), a leading provider of information
technology and business process services, announced today that Mr. Bernard
Bourigeaud, Founder and former Chairman of Atos Origin, has joined the CGI Board
of Directors.

Mr. Bourigeaud is currently Chairman of BJB Consulting, a
CEO to CEO consultancy business. Over his career, Mr. Bourigeaud has established
himself as a successful entrepreneur and a prominent business leader in Europe.
Mr. Bourigeaud grew his reputation as an astute business man when he transformed
Atos Origin from a small regional player with €300 million in revenue and 3000
employees, into a global company with more than €5 billion in revenue and 50,000
employees.

Mr. Bourigeaud’s chain of successful mergers began in 1991
when he conducted the merger of SITB, Sodinforg and Segin leading to the
creation of Axime, of which he became Chairman. In 1996, he was responsible for
Axime’s acquisition of Sligos and the subsequent formation of Atos, of which he
was Chairman and CEO. In November 2000, he merged Atos with Origin, a subsidiary
of Royal Philips Electronics in the Netherlands, creating Atos Origin. In 2002,
he completed the acquisition of KPMG Consulting in the UK and the Netherlands,
now operating in these two countries under the name of Atos Consulting. In 2003,
Mr. Bourigeaud led Atos Origin’s acquisition of SchlumbergerSema to create a
leading global IT services company with annual revenues of €5 billion. Finally,
in 2006, he completed the acquisition of Banksys and BCC (Bank Card Company),
creating a leadership role in Europe for the payments industry.

Prior to
joining Axime, Mr. Bourigeaud spent 11 years at Deloitte Haskins and Sells where
he headed the management consulting group. He was responsible for the French
operation where he created the European mergers and acquisitions division. For
eight years preceding this, he worked for the agribusiness company Continental
Grain, carrying out various general management assignments in Europe for three
years and running the UK operations for five years. Mr. Bourigeaud’s career
began with the French bank, CIC, and Price Waterhouse.

Mr. Bourigeaud
holds positions on various boards. He is Senior Advisor to Apax Partners in
France. He also serves on the Board of CEPS (Centre d'Étude et Prospective
Stratégique), an independent and multidisciplinary think tank based in France,
and he is advisor to the National Committee of French Foreign Trade (CNCCEF). In
2007, Mr. Bourigeaud was appointed Affiliate Professor at HEC School of
Management in Paris and he is a member of HEC’s International Advisory Board. In
2004, he was appointed Chevalier de la Légion d’Honneur.

“We are very
pleased to welcome Mr. Bourigeaud to the CGI Board of Directors,” said Serge
Godin, Founder and Executive Chairman. “His vast experience in information
technology, finance and consulting, and his understanding of the global market
place will contribute to the execution of our global strategy. I look forward to
collaborating closely with him on the realization of CGI’s goals.”

Mr.
Bourigeaud replaces Mr. C. Wesley M. Scott who is stepping down from the board
after seven years of service. This leaves the total number of CGI Directors at
14.

“I would like to thank Mr. Scott for his valuable counsel,” added
Mr. Godin. “His experience and financial acumen have both contributed to CGI’s
success.”
