                         COLAS 1st quarter 2010 
       Business was penalized by unfavorable weather conditions.

   The Colas Group's consolidated revenue at the end of March 2010 totaled
1.828 billion euros, compared to 1.972 billion euros at the end of March 2009, a
7.3% decrease (-7.7% with comparable exchange rates and scope of business). A
breakdown of these figures shows that France accounted for 1.223 billion euros
(-5.9%) and the international units for 605 million euros (-10.1%).

   Business was put at a sharp disadvantage by very harsh winter weather in
France (especially in January and February), Europe and North America. Climate
conditions were even worse than those recorded during the 1st quarter 2009.

   It is important to underline that 1st quarter activity is not highly
significant, due to the strong seasonal nature of the majority of Colas'
businesses.

   Work-on-hand remains high at the end of March 2010 with 7.0 billion euros,
slightly more than the 6.7 billion euros recorded at the end of March 2009.
