Bouygues Construction reported a 6% drop in sales. Stable on
international markets, sales fell by 10% in France, where activity was
affected by poor weather.

The order intake in the first quarter rose by 25% compared
with the same period in 2009, to EUR2.8 billion. This figure includes the
Barwa Financial District project in Qatar. The order book stood at a record
level of EUR12.7 billion, up 6% on end-December 2009 and 4% on end-March
2009.

Sales at Bouygues Immobilier were almost stable, with a 16%
rise in residential property and a 30% decline in commercial property.

Business activity in the first quarter of 2010 reflected the
same trend as in 2009. Residential property reservations rose 46% to EUR494
million but the commercial property market remained sluggish. Overall,
first-quarter 2010 reservations were up 43% at EUR500 million. The order book
stood at EUR2.1 billion, 4% less than at end-December 2009 and 29% lower than
at end-March 2009.

Colas recorded a 7% decline in sales, down 6% in France and
10% internationally, hit by a particularly severe winter. Given the strong
seasonal nature of Colas' activities, first-quarter sales are not that
representative of the entire year.

The order book at end-March 2010 remained high at EUR7.0
billion, up 13% on end-December 2009 and 4% on end-March 2009.

Sales at TF1 rose by 11%, driven by an upturn in the
advertising market in a still uncertain economic environment.

Bouygues Telecom posted a 5% increase in sales. Sales from
network grew 5% to EUR1,237 million. Stripping out the impact of the cut in
voice and SMS termination rates, growth would have been 13%.

At 31 March 2010, Bouygues Telecom had 10,394,000 mobile
customers, 8,075,000 of whom were on call plans, or 77.7% of the total
customer base, an increase of 2.3 points over one year. 149,000 new mobile
customers on call plans joined Bouygues Telecom in the first quarter of 2010,
representing 24% of net market growth.(1)

The Fixed-line business continued to perform strongly,
registering 117,000 net activations in the first quarter of 2010. At 31 March
2010, 428,000 Bbox routers had been activated(2), a year-on-year increase of
399,000.
