decrease of 2% compared to total revenue of (Euro)178.8 million in the 2001
third quarter. On a constant currency basis, total revenue increased 3%.
Software revenue, representing 85% of total revenue, decreased 4% to (Euro)149.5

SolidWorks seats.

Process-centric revenue, including PDM revenue, totaled (Euro)145.5 million in
the third quarter of 2002, broadly flat with the year-ago period (2001:
(Euro)146.0 million) and represented 83% of total revenue. On a stand-alone
basis, PDM revenue led by strong growth in both software and service revenues,
increased 32% to (Euro)19.6 million, up from (Euro)14.9 million in the third
quarter of 2001 and accounted for 11% of total revenue in the 2002 third
quarter. PDM software end-user revenue totaled (Euro)27.6 million.
Design-centric revenue, representing 17% of total revenue, decreased 7% to
(Euro)30.4 million, compared to (Euro)32.8 million in the year-ago quarter.

Net income excluding acquisition costs was (Euro)24.3 million or (Euro)0.21 per
share in the 2002 third quarter, a decrease of 16% on a per share basis compared
to (Euro)28.3 million or (Euro)0.25 per share in the year-ago quarter. On a US
GAAP basis, which includes acquisition costs, net income increased 46% to
(Euro)22.0 million or (Euro)0.19 per share in the third quarter of 2002 compared
to (Euro)15.1 million or (Euro)0.13 per share in the 2001 third quarter. The
Company had a strong balance sheet with no long-term debt and cash and
short-term investments totaling (Euro)397.3 million at September 30, 2002.

Nine Months
-----------

For the 2002 nine-month period, total revenue increased 6% to (Euro)549.7
million, compared to (Euro)520.8 million in the respective 2001 period. On a
constant currency basis, total revenue increased 8% for the nine months ended
September 30, 2002. Net income excluding acquisition costs decreased 7% to
(Euro)82.8 million or (Euro)0.71 per share, compared to (Euro)89.2 million or
(Euro)0.77 per share in the comparable 2001 period. On a US GAAP basis, which
includes acquisition costs, net income was (Euro)75.0 million or (Euro)0.64 per
share for the nine months ended September 30, 2002, up 60% compared to
(Euro)46.6 million or (Euro)0.40 per share in the year-ago nine-month period.
Year-to-date, 41,718 seats were licensed, comprising 24,112 CATIA and 17,606
SolidWorks seats.

Process-centric revenue, including PDM revenue, increased 7% for the first nine
months of 2002 to (Euro)454.2 million (2001:(Euro)426.6 million). PDM revenue on
a stand-alone basis increased 22% to




(Euro)51.8 million (2001:(Euro)42.6 million) and Design-centric revenue
increased 1% to(Euro)95.5 million (2001:(Euro)94.2 million).

Charles Edelstenne, Chairman of DS, stated, "Business conditions continue to be
tough around the world. While DS is clearly not immune, our market leadership
and winning brands, high level of recurring revenues and strong financial
position have enabled us to show results that are comparatively better than most
of our industry."

Bernard Charles, President and Chief Executive Officer, commented, "We continued
to make very solid progress on our strategic initiatives in PLM. Our PDM
business has performed well throughout the year and this quarter was no
exception. Led by ENOVIA, PDM revenue grew by 32%, exceeding our expectations.
The introduction of new sales channels at SmarTeam is on track with IBM and
SolidWorks, and is starting to ramp up. Digital manufacturing, with DELMIA, had
a good quarter as customers continue to realize the significant benefits of our
digital manufacturing software. Turning to CATIA, V5 sales continued to
strengthen with new and long-standing customers and represented two-thirds of
CATIA seats licensed in the quarter. The upcoming V5 Release 10 will further
improve the entry PLM capabilities as well as performance and scalability for
large accounts. And IBM continues to ramp up resources in accordance with our
joint growth plan for addressing the significant opportunities in the PLM
market. In summary, in spite of the sudden slowdown we encountered this quarter
due to the economic environment, I believe we are positioned to increase our
number one market share position in PLM during 2002."

"The design-centric market has been more affected than our 3D PLM businesses by
the weakness in business spending, as it is mostly focused on small and
medium-sized companies. When economies around the world improve, we believe
these same companies are likely to commence investment spending at the initial
stages of a recovery. Based upon SolidWorks market leadership and robust
software which is heavily used in production, we believe SolidWorks is
well-positioned to be an early beneficiary of an improving business
environment."

Thibault de Tersant, Executive Vice President and CFO, commented, "Revenues came
in modestly below that of the year-ago quarter, reflecting the weaker economic
environment as well as the



impact of the significant currency fluctuations and our new growth plan with IBM
announced in July. In combination, currency changes and the new IBM royalty
agreement resulted in a revenue reduction of approximately (Euro)13 million
without which revenue would have increased by 6% during the third quarter.

"As we look to the fourth quarter, we are reaffirming the objective that we
provided to the market in late September, where we stated that total revenue
could equal or slightly exceed 2001 fourth quarter revenue of (Euro)225 million.
On the expense side we are working diligently to monitor and manage our costs in
order to maintain our operating margin at a stable level. We are meeting with
good success here and believe our efforts position us to achieve an operating
margin of approximately 36% in the fourth quarter, unchanged from the fourth
quarter of 2001. In summary, we believe we are on target to meet our full year
objectives of revenue growth of approximately 4% and an operating margin of
approximately 27-28%.

"We are taking a very conservative posture with respect to 2003 at this point in
time. We anticipate that current business conditions will persist through next
year and as a result, our number one financial goal is focused on delivering a
stable operating margin within an environment of modest annual revenue growth of
2-3% for the Company."

                     Pratt & Whitney Canada Selects IBM and
            Dassault Systemes for Innovative Digital Engine Program


               IBM Product Lifecycle Management solution featuring
             CATIA - ENOVIA from Dassault Systemes will be platform
           for ambitious aerospace initiative based on e-collaboration


Montreal, Canada and Paris, France - October 23, 2002 - IBM and Dassault
Systemes (Nasdaq: DASTY, Euronext Paris: #13065, DSY.PA) today announced that
Pratt & Whitney Canada has selected an IBM Product Lifecycle Management Solution
centered on CATIA V5, ENOVIAVPM, and ENOVIA 3d com from Dassault Systemes to
develop new engines using digital technology. The agreement calls for IBM and
Dassault Systemes to deliver 200 CATIA V5 seats by the end of 2002, and up to
300 more in 2003.

Through its Digital Engine initiative, Pratt & Whitney Canada's goal is to
become the first company in the aerospace industry to develop engines using
digital technology throughout the entire design and manufacturing process. The
agreement also requires IBM to deliver Dassault Systemes' ENOVIAVPM and ENOVIA
3d com product data management solutions to enable e-collaboration throughout
Pratt & Whitney's engineering and product support functions. The CATIA - ENOVIA
Solution will ensure that Pratt & Whitney Canada customers, partners, suppliers,
and employees will be able to interact and collaborate in the 3D design process
of its engines.

"We have partnered with IBM and Dassault Systemes for earlier versions of
CATIA-based systems to design engines and simulate performance with great
success," said Amal Girgis, Chief Information Officer, Pratt & Whitney Canada.
"Upgrading to the newest version of CATIA will certainly help us to reach the
efficiency goals of the Digital Engine initiative much faster. The deployment is
on schedule with more than 80 CATIA V5 seats installed and in use today."

         Launched in 2001, the Digital Engine represents one of the major
components of Pratt & Whitney Canada's broader Digital Enterprise program
scheduled to last three to five years. It will enable designers to work on
engines concurrently in a virtual environment with other project stakeholders.
Using PLM solutions from IBM and Dassault Systemes, the company will soon be
able to link remaining components of the Digital Enterprise initiative,
including Enterprise Resource Planning (ERP), Supply Chain Management (SCM) and
Customer Relationship Management (CRM).

"E-collaboration is playing a critical role in making companies more competitive
and IBM's product lifecycle management solutions are a major part of this
competitive advantage, delivering improvements in development costs, quality,
and time to market," said Tom Kilkenny, vice president, IBM Product Lifecycle
Management Americas. "With new cost pressures and speed-to-market taking on even
greater importance within the aerospace industry, Pratt & Whitney Canada's drive
to bring real-time access to information through the full product life cycle
will further help to provide a competitive advantage moving forward."

"CATIA V5 delivers cutting-edge technology and incomparable ease of use, and
combined with ENOVIA, contributes to rapid market response in sectors such as
the aerospace




industry where shortening product development cycles is critical," said Philippe
Forestier, executive vice president, Sales and Marketing, Dassault Systemes. "We
are delighted to see that our 3D PLM solutions bring immediate benefits and help
Pratt & Whitney Canada accelerate the drive toward its world-class, Digital
Enterprise vision."
