currencies in comparison to the year-ago period. Design-centric revenue totaled
(euro)92.0 million for the 2003 nine-month period, representing a decrease of
4%, but increases of 10% in constant currencies and 16% in U.S. dollars compared

comprised of 21,670 CATIA and 18,293 SolidWorks seats.

Bernard Charles, President and Chief Executive Officer, commented, "We set two
key strategic priorities at the outset of 2003: First, to expand our number one
market share position in PLM beyond the 21% achieved in 2002. And second, to
improve our operating margin by up to 1 percentage point, while continuing to
invest in our future as demonstrated by the 4% increase in our R & D headcount
for this year. Based upon our performance year-to-date and our outlook for the
fourth quarter, we believe we are well positioned to achieve these goals.

"DS made good progress in the quarter within a continued cautious spending
environment on the part of our customers as demonstrated by our revenue increase
of 15% when measured in U.S. dollars, outperforming the competition. CATIA V5
continued to gain traction among existing customers and the supplier network.
Moreover, a clear highlight of the quarter is the fact that we are now also
seeing the beginning of true PLM wins within the supply chain, including
decisions by Bosch and Sanyo Machine Works. Version 5 Release 12 was introduced
for CATIA, DELMIA, ENOVIA and SMARTEAM. At the heart of our new release is
Collaborative PLM, enabling companies to move closer to becoming on demand
businesses.

"New companies continue to join our CAA V5 partnership program, resulting in a
broad offering of complementary solutions built on top of our V5 open
architecture. Our partners number over 36 with the addition of Fluent and
IGE+XAO this quarter. Today, we also announced a strategic software development
agreement with Gehry Technologies to create and sell 3D collaborative solutions
to the building industry based upon our CAA V5 development platform."

Thibault de Tersant, Executive Vice President and CFO, commented, "The third
quarter was marked by several highlights. Software revenue growth was in-line
with our expectations, increasing 9% in constant currencies. Our continued focus
on growing our operating margin through careful cost management met with
favorable results, with a 3 percentage-point improvement over last year to 25.0%
before acquisition costs. And earnings were solid, coming in ahead of our
expectations. Services, however, did not meet our expectations, resulting in
total revenue approximately (euro)4 million lower than our objective when
adjusted for actual currency rates.

"For the fourth quarter, we believe a revenue objective of about (euro)225
million is appropriate as we continue to be cautious about the economic
environment. For the full year, we are maintaining our objective for operating
margin growth of up to 1 percentage point above the operating margin of 27.7%
before acquisition costs achieved in 2002. And, from an earnings perspective, we
are also maintaining our EPS objective of (euro)1.22 to (euro)1.25 per share
before acquisition costs. These objectives for revenue and earnings continue to
be based upon an assumed U.S. dollar to Euro exchange rate of $1.20 per
(euro)1.00 for the fourth quarter. We are modifying our revenue growth objective
for 2003, reflecting lower service revenue in the second half of the year and
our outlook for the fourth quarter. Our 2003 revenue growth objective in
constant currencies is now 5% to 6%.

"Looking ahead to 2004, we are providing our preliminary views at this time. Our
revenue growth objective is about 6% to 7% in constant currencies. Taking an
assumed U.S. dollar to Euro exchange rate of $1.20 per (euro)1.00, therefore,
leads to a reported revenue growth objective of approximately 4 to 5%. At this
point in time, our financial objectives assume a continuation of the current
business environment into 2004."

During the third quarter, the Company's free float increased to 48% from 32% as
a result of the French government's sale of its entire holding in DS. The French
government had been a shareholder since May 31, 2001 as a result of DS'
de-merger from its former parent company, Dassault Aviation, in which the
Government was an equity holder. Following this sale, the shareholder base of DS
is composed as follows: free float of approximately 48.0%, Groupe Industriel
Marcel Dassault with 45.2%, and Charles Edelstenne, Chairman of Dassault
Systemes with 6.8%.

Charles Edelstenne, Chairman, commented, "We were pleased by the level of
interest in our stock during the French government's sale of its DS shares which
was oversubscribed more than four times. It reflects the confidence of investors
in the strong fundamentals of our business and our strategy."

                               BUSINESS HIGHLIGHTS

NEW PRODUCT LAUNCHES

DS introduced Version 5 Release 12 -- Collaborative PLM for on demand
businesses. V5R12 allows critical PLM components to be merged in collaborative
workspaces allowing lifecycle management and product design activities to be
conducted in parallel while ensuring synchronization of collaboration in the
context of correct, up-to-date data. New capabilities in ENOVIA Portal 3d com,
including enhanced CATIA-ENOVIA integration, allow 3D data, product structure,
and other relevant product information to be shared in real-time through web
portals.

The new V5R12 product portfolio brings business value to manufacturers in the
following areas:

     o    Core Business - V5R12 enables companies to organize activities around
          their core business and focus on products. V5R12 redraws the
          boundaries between traditional product authoring and PDM-related
          activities, providing users with unified PLM workspaces in which they
          can process all facets of their activity.
     o    Content for Collaboration - V5R12 helps companies deliver the right
          content for collaboration throughout the product lifecycle. This
          improves exchanges between extended enterprise teams and helps
          businesses respond rapidly to market change.
     o    Requirements and Specifications - V5R12 allows companies to better
          link product design with requirement and specification management in
          order to dynamically adapt to market demand.
     o    Manufacturing Resources - V5R12 provides a unified workspace that
          connects product creation and manufacturing resources definition to
          help companies make cost-efficient production decisions.

During the third quarter, DS introduced a PLM industry solution for aerospace
manufacturers based on proven DS PLM Practices. The Best of Breed Structure
Engineering solution integrates the activities and processes required to design
and manufacture structural aircraft parts and assemblies (sheetmetal, machined,
and composite parts) as well as the corresponding tools required to build them.

CUSTOMERS AND PARTNERS HIGHLIGHTS

The First Aircraft Institute of AVIC-I (FAI), a leading Chinese aircraft
research institute, has selected DS PLM solutions to develop China's Advanced
Regional Jet Program, ARJ21. CATIA V5 for collaborative product design and
digital mock-up creation, and ENOVIAVPM for product data and process management,
will enable the institute's engineering teams to share data and work in a common
3D development environment across its multi-site operations.

Bosch, a major automotive supplier, has invested in DELMIA process planning
solutions to meet the requirements outlined for DaimlerChrysler's "Digital
Factory" initiative. Bosch celebrated the introduction of its Cooperative
Engineering program (COPE), with DELMIA Process Engineer at its core, as a
"quantum leap in production planning". The COPE program offers computer-aided
production planning in parallel with product development. Benefits of simulated
production planning include the identification and elimination of potential
problems in a virtual environment, before they become real and incur damage and
costs.

Convenience Food Systems (CFS) has standardized on SolidWorks software to design
the industrial food processing and packaging machines it sells to global food
companies. SolidWorks 3D mechanical design software accelerates large-assembly
design for CFS' machines, while COSMOS analysis software reduces production
errors so CFS can speed products to customers. Based in the Netherlands, CFS is
one of the world's foremost convenience food packaging, preparation, processing,
and marination machine makers.

Evernham Motorsports LLC, a leading NASCAR Winston Cup Series race team, has
selected CATIA V5 for collaborative product development and SMARTEAM for
collaborative lifecycle management to develop high-performance race cars through
virtual testing rather than building costly, full-scale physical prototypes.
