Zurich, Switzerland, January 26, 2010: Adecco Group, the world's leading

Appeal on the antitrust proceedings involving Adecco and Adia France and its
main competitors in France. The EUR 34 million fine, imposed on February
2, 2009, remains unchanged.

The Court rejected Adecco's appeal against the decision of the French
Competition Council (Conseil de la Concurrence), which on February 2, 2009 had
imposed a fine of EUR 34 million. Adecco and Adia France will not appeal this
decision. As of December 31, 2008, Adecco has already recorded a provision for
the total amount of the fine.
