PARIS, FRANCE, July 24, 2003 - Dassault Systemes (DS) (Nasdaq: DASTY; Euronext
Paris: #13065, DSY PA), a worldwide leading software developer of product
lifecycle management (PLM) solutions, reported financial results for the second
quarter and six months ended June 30, 2003.

FINANCIAL HIGHLIGHTS
Second Quarter
--------------
Total revenue was (euro)181.3 million in the second quarter of 2003. On a U.S.
GAAP basis net income was (euro)28.2 million or (euro)0.25 per diluted share in
the 2003 second quarter compared to (euro)27.7 million or (euro)0.24 per diluted
share in the second quarter of 2002, representing a 4% increase on a per share
basis. Net income excluding acquisition costs was (euro)29.3 million or
(euro)0.26 per diluted share in the second quarter, compared to (euro)30.0
million or (euro)0.26 per diluted share in the second quarter of 2002.

Total revenue in the second quarter of 2003 decreased 5%, but increased 4% on a
constant currency basis in comparison to the year-ago quarter. In the second
quarter of 2003 software revenue, representing 84% of total revenue, equaled
(euro)151.8 million. In comparison to the year-ago period, software revenue
decreased 9%, but was flat on a constant currency basis. An important component
of revenue is recurring software revenue, which represented 54% of total
software revenue in the second quarter. Seats licensed in the second quarter of
2003 totaled 13,568 with 7,259 CATIA and 6,309 SolidWorks seats.

Services and other revenue increased 20% in the second quarter of 2003,
primarily reflecting the increase in the number of PLM projects underway.

Specifically, services and other revenue totaled (euro)29.5 million and
represented 16% of total revenue in the second quarter of 2003.

Process-centric revenue, including PDM revenue, totaled (euro)150.1 million in
the recently completed quarter. Process-centric revenue decreased 6% in
comparison to the year-ago quarter but increased 2% in constant currencies. On a
stand-alone basis, PDM revenue in the second quarter of 2003 increased 17% and
in constant currencies increased 26%, both in comparison to the year-ago period.
Specifically, PDM revenue increased from (euro)17.4 million in the year-ago
quarter to (euro)20.3 million in the second quarter of 2003. PDM end-user
software revenue totaled (euro)28.5 million. Design-centric revenue totaled
(euro)31.2 million in the second quarter of 2003, a decrease of 4% compared with
(euro)32.4 million in the year-ago quarter but an increase of 18% in U.S.
dollars. PDM revenue represented 11% and design-centric revenue accounted for
17% of total revenue.

The Company had a strong financial position with cash and short-term investments
totaling (euro)420.1 million and no bank debt at June 30, 2003.

DS held its annual general shareholders' meeting on May 28, 2003. At that time,
shareholders approved the payment of a 2002 cash dividend (excluding avoir
fiscal) of (euro)0.33 per share, representing approximately (euro)37.2 million
or 29% of 2002 U.S. GAAP net income. The 2002 cash dividend including avoir
fiscal was (euro)0.50 per share.

First Half Results
------------------

Total revenue was (euro)350.7 million for the first six months of 2003, compared
to (euro)373.8 million in the year-ago period, representing a decrease of 6%,
but an increase of 2% in constant currencies. On a U.S. GAAP basis net income
totaled (euro)50.5 million or (euro)0.44 per diluted share for the first half of
2003, compared to (euro)53.0 million or (euro)0.45 per diluted share,
representing a 2% decrease on a per share basis. Net income excluding
acquisition costs was (euro)53.5 million or (euro)0.47 per diluted share for the
first half of 2003, representing a decrease of 6% on a per share basis, compared
to (euro)58.5 million or (euro)0.50 per diluted share for the year-ago period.

Charles Edelstenne, Chairman of DS, stated, "DS delivered solid financial
performance in the second quarter, illustrating the strength of our market
leadership as well as the resiliency of our business model within a weak
business environment. Our focus continues to be on outperforming the PLM market
under any economic scenario and I believe our financial results to date
demonstrate the competitiveness of our PLM solutions."

Bernard Charles, President and Chief Executive Officer, commented, "I believe we
are growing our market share in PLM and widening the gap between DS and

our competitors as evidenced by our first half revenue increase of 15% when
measured in U.S. dollars. We have made good progress so far this year and
believe we are in a favorable position to deliver full year revenue growth of
about 7% in constant currencies, as well as operating margin and EPS growth in
2003.

"Large-scale production deployments of our V5 PLM solutions (CATIA, DELMIA,
ENOVIA, SMARTEAM), demonstrating significant ROI, are underway in our core
markets with leading-edge customers. And we are seeing traction with the
supplier networks, including new Version 5 wins in the quarter with Koito
Manufacturing, an automotive lighting equipment company in Japan, CIMOS, a
Slovenian automotive supplier and Heroux-Devtek, a Canadian aerospace supplier.
Our PDM business, with ENOVIA and SMARTEAM continues to make strong headway,
with 25% revenue growth in constant currencies for the first half. SolidWorks,
focused on the design-centric market, has clearly regained momentum in 2003,
with revenue growth of 16% in U.S. dollars for the 2003 first half and an
expanded sales channel capacity as we move forward.

"In summary, I believe our solid performance during this extended period of
economic weakness clearly indicates that DS' solutions and people are providing
our customers with more than software applications - we are working closely with
our customers to deliver significant business value with our PLM solutions."

Thibault de Tersant, Executive Vice President and CFO, commented, "As we had
anticipated, the overall economic environment continued to be tough in the
second quarter. Moreover, currency fluctuated a good deal in the quarter, with
further weakening of the U.S. dollar and Asian currencies. We were, therefore,
pleased to report in line financial results for the second quarter, with total
revenue within our target range of (euro)180 to (euro)185 million. In fact,
revenue would have been at the high end of our range if currency levels had
remained consistent with our guidance assumptions. Our operating margin also
came in on target and showed year over year improvement.

"While we continue to be cautious with respect to any improvement in the
economic environment in the second half of the year, based upon first half
results and our business outlook, we are reconfirming our full year revenue
growth objective of about 7% in constant currencies and our operating margin
growth objective of up to 1 percentage point above the 27.7% operating margin
achieved in 2002. Currency market experts anticipate further weakness,
particularly in the U.S. dollar and Asian currencies as the year progresses. At
this time we believe it is prudent to assume a U.S. dollar to Euro exchange rate
of $1.20 per (euro)1.00 for the remainder of the year, the consensus figure of
leading banks. This new exchange rate assumption would lead to reported revenue
of about (euro)760 million and an EPS range of approximately (euro)1.22 to
(euro)1.25. For the third quarter we believe a revenue objective of (euro)175 to
(euro)180 million is appropriate."
