Dassault Systemes S.A. (the "Company") is furnishing under cover of Form 6-K, a
press release dated February 13, 2003, announcing that Delmia Corp., a Dassault
Systemes company, announced that Sumitomo Wiring Systems Ltd. (SWS), a leading
wire harness manufacturer, has reduced product development cycles by using
DELMIA's ENVISION(R) and QUEST(R) solutions.

                  DELMIA Solutions Help Sumitomo Wiring Systems
                      Slash Product Development Time by 67%

              Company's Virtual Visual Assembly System Cuts Product
               Development Cycles, Improves Internal Collaboration

Yokohama, Japan -- February 13, 2003 -- Delmia Corp., a Dassault Systemes
company (Nasdaq: DASTY; Euronext Paris: #13065, DSY.PA), today announced that
Sumitomo Wiring Systems Ltd. (SWS), a leading wire harness manufacturer, has
reduced product development cycles by using DELMIA's ENVISION(R) and QUEST(R)
solutions to simulate the manual assembly of its products. By implementing
Delmia Corp.'s digital manufacturing solutions and increasing collaboration with
car manufacturers, SWS has decreased its overall development time by 67 percent.

In 1998, SWS launched its virtual Visual Assembling System (VAS), with DELMIA's
ENVISION and QUEST at the core of the system, to facilitate concurrent
engineering among design, production engineering, and manufacturing divisions. A
car's wire harness consists of approximately 4,000 parts. The assembly process
is done manually and is difficult to optimize. In the past, SWS used a physical
mock-up methodology to define, validate, and optimize the assembly process.
However, due to time and cost constraints, it was difficult to cover the entire
production operation and integrate all design and production change

Today, the Virtual Assembly System at SWS helps the company condense development
cycles, detect early assembly problems during development, and accelerate
production ramp-up times. VAS also conducts many virtual iterations of the
company's wire harness development, including design, assembly, and production
flow. The SWS production engineering department utilizes ENVISION to check
interferences between jigs and wires, validate wire harness assembly layouts
while considering operators' workability, and check twists and lengths of wires
where harnesses are built into vehicles. Moreover, with QUEST, SWS optimizes
line development by modeling the layout of the entire factory and virtually
simulating the production flow before the factory is built.

"Through several development projects using VAS, we clearly see the
effectiveness of Delmia Corp.'s digital manufacturing solutions," said Koichi
Sakakura, project leader for VAS Development Group in SWS's production,
engineering, and development department. "SWS intends to expand its concurrent
engineering efforts by heavily using 3D data and strengthening collaboration
between the design and production departments. Moreover, this system enables
employees to share and utilize knowledge more efficiently, and reinforces our
strong relationships with car manufacturers."

"The successful deployment of DELMIA ENVISION and QUEST at SWS is a meaningful
case study," said Bertrand Saint-Martin, president of Delmia Japan, Ltd. "Since
wire harnesses at SWS are assembled manually, this process was not simulated
with digital manufacturing tools. This success story proves that DELMIA's
solutions can now address a wider range of processes, enabling our customers to
further decrease development cycles."
