 Dassault Systemes S.A. (the "Company") is furnishing under cover of Form 6-K a
   press release dated May 24, 2004, announcing that the Company and Dassault
     Aviation have together developed the Falcon 7X jet, the first aircraft
                    entirely developed on a virtual platform.

   Dassault Aviation and Dassault Systemes Make Industry History -- Falcon 7X
       Jet Becomes First Aircraft Entirely Developed on Virtual Platform

  Pioneering aircraft manufacturer cuts assembly time of high-end business jet
              by 50% with V5 PLM solutions from Dassault Systemes

Paris, France - May 24, 2004 - Just one year after implementing a revolutionary
virtual product development platform - the "Virtual Plateau" - based on Dassault
Systemes (Nasdaq: DASTY: Euronext Paris: #13065, DSY.PA) Product Lifecycle
Management (PLM) Solutions, Dassault Aviation has halved the time required to
assemble its new Falcon 7X business jet.

The Falcon 7X becomes the first aircraft in industry history to be entirely
developed in a virtual environment, from design to manufacturing to maintenance.
The single, integrated PLM environment, based on Dassault Systemes' CATIA,
ENOVIA, and DELMIA Solutions, enables Dassault Aviation and its 27 partners in
seven countries to work on a common, collaborative, 3D virtual platform. In
addition, SMARTEAM was used to manage and track airplane systems.

Every one of the jet's 30,000 parts was designed with CATIA. Through ENOVIA,
more than 1,000 engineers manage, exchange, and work in real-time on up-to-date
designs, including interface data for partner-designed sections. With DELMIA and
its human modeling modules, specialists analyze and optimize the design of the
Falcon 7X for crucially important aircraft maintenance and repair procedures.

The dramatic gains in assembly time and part quality stem from the precision
attainable on the virtual platform. The digital mockup of the Falcon 7X is so
accurate that fittings, supports, and tubing developed virtually fit perfectly
when the aircraft parts are assembled in the physical world. Not only has the
need for traditional assembly tools dropped dramatically, but Dassault Aviation
will also not produce a physical prototype of the Falcon 7X. The first jet,
scheduled for delivery in March 2005, will immediately be used for

"We made a big gamble when we said we were going with ENOVIA," said Jean-Claude
Hironde, deputy senior vice-president, Research, Design and Engineering,
Dassault Aviation. "Initially, we had to convince our partners of the benefits
of a virtual platform, of sharing data, and working in context. But today, with
data updated overnight, as opposed to the former two-month modification cycle,
there simply is no comparison."

"The virtual platform has fundamentally changed the way we view building
airplanes," said Jacques Pellas, CIO, Dassault Aviation. "Adopting PLM means
improving the circulation of information in a company, redefining its processes,
and reorganizing company structures. We are just at the beginning of a new
industrial revolution."

"By becoming the first aerospace manufacturer to implement a "virtual plateau",
Dassault Aviation has proven once again to be a pioneer in the industry," said
Philippe Forestier, executive vice-president, Dassault Systemes. "All users of
this virtual plateau--from suppliers to Dassault Aviation's own engineers--are
establishing new frontiers in aircraft development and demonstrating the value
of the PLM business transformation."
