Dassault Falcon 900LX Flight Test Program Enters Into its Last Phase; Begins Completions on First Customer Aircraft

GENEVA, May 3, 2010 - Dassault's Falcon 900LX has entered the last phases of the
flight test and certification program while completions on the first two
customer aircraft have begun. Final certification is anticipated during the
third quarter of 2010 with deliveries starting thereafter.

The flight test program, which began in October of 2009, has
accumulated 180 flight hours over 72 flights. Handling qualities of the
airplane, take-off and landing performance, stalls at various speed
configurations, flights in icing conditions, maximum operating speed, as well
as simulated system failures have been tested extensively in addition to
aircraft fuel consumption. The aircraft performed as expected and confirmed
reductions in drag and higher climb performance over the Falcon 900EX EASy
which it will replace.

More than half of the certification flights have been
performed to date with EASA certification pilots. Crosswind trials are
planned in the next few weeks.

The 4,750 nm Falcon 900LX is built on the Falcon 900EX EASy
platform and includes a pair of High-Mach Blended Winglets designed by
Aviation Partners Inc. The wing aerodynamic improvement will help reduce
aircraft drag as much as 5% offering corresponding range and efficiency
improvements. Time to climb to cruise altitude will also be reduced by 10%.
As a consequence, the Falcon 900LX is as much as 50% to 60% more efficient
than other airplanes in its class.

"Our thorough flight test program has demonstrated the
improved efficiencies of the Falcon 900LX," said John Rosanvallon, President
and CEO of Dassault Falcon. "Falcon 900LX operators will be confident in the
fact that they operate the most efficient airplane in its class. It burns
less fuel and creates fewer emissions. That's a very positive message in
today's closely scrutinized business world."

The Falcon 900LX can connect a wide variety of commonly used
cities, including New York with Moscow, Paris with Beijing, Washington with
Sao Paulo, Dubai with Tokyo and Caracas with Geneva.
