Dassault Systemes S.A. (the "Company") is furnishing under cover of Form 6-K a
press release dated October 7, 2002, announcing that L'Oreal researchers are
using CATIA V5 computer-assisted design (CAD) software from Dassault Systemes
for education and research on the hair follicle.

                    L'OREAL AND DASSAULT SYSTEMES TEAM UP TO
               REVEAL THE SURPRISING STRUCTURE OF HAIR IN 3D WITH
                                    CATIA V5

CLICHY, FRANCE, OCTOBER 7, 2002 - L'Oreal Recherche and Dassault Systemes today
announced that L'Oreal researchers are using CATIA V5 computer-assisted design
(CAD) software from Dassault Systemes for education and research on the hair
follicle. The three-dimensional images present the mini-organ as it has never
been seen before.


There are 150,000 follicles in the scalp. Each is associated with a muscle, a
sebaceous gland, and a sweat gland. The follicle produces hair fiber for about
three years at which point a phase of rapid degeneration occurs (three weeks)
followed by a three-month rest phase during which the hair falls out. In a
process unique to humans, the follicle then regenerates itself from stem-cell
reservoirs and once again begins production of the hair.


To date, one of the biggest challenges facing L'Oreal scientists was the
difficulty of creating a clear and concise three-dimensional image of the
follicle. With CATIA V5, they can now create mock-ups or virtual models and
visualize in 3D the relative position of the different components of this
familiar yet surprising part of the body. The benefits are both educational and
scientific.


"Existing solid models of hair are not adapted for handling. Histological cuts
have been performed with 2D tools, and it has not been possible to visualize,
manipulate, or modify at will in space the different elements of the follicle.
By enabling a virtual mock-up of a hair, CATIA V5 finally permits us to capture
the complexity of this organ in space," said Bruno Bernard, Project Director,
Hair Biology Research, L'Oreal. "CATIA V5 is an exceptional learning tool that
not only allows virtual cuts from all angles and levels desired, but also
facilitates understanding of the internal constraints and changes this organ
undergoes during its cycle."


"This partnership between L'Oreal and Dassault Systemes is very significant
because it expands the scope of 3D Product Lifecycle Management (3D PLM)
solutions such as CATIA V5," said Etienne Droit, executive vice president, sales
and marketing, Dassault Systemes. "Traditionally, CATIA V5 has been used to
design cars, planes, and machinery. L'Oreal is now using CATIA to study a living
object. The long-term perspectives are very exciting because the same approach
could be applied to study different parts of the body, such as skin for
example."
