DASSAULT SYSTEMES REPORTS SOLID FIRST QUARTER PERFORMANCE, WITH REVENUE, OPERATING MARGIN AND EPS ABOVE OBJECTIVES PARIS, FRANCE, April 29, 2004 - 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 first quarter ended March 31, 2004.

Our financial results exceeded our objectives, with revenue, operating margin and earnings per share coming in higher than targeted. These results are mainly attributable to our better than anticipated performance in Europe. We continued to benefit from our diversification strategy, as illustrated by the good growth of our PDM business. SolidWorks also had a good start to the year, with revenue increasing 25% in U.S. dollars during the first quarter. We are raising our revenue and earnings growth objectives for 2004 to reflect the fact that our first quarter came in above our objectives," commented Bernard Charles, President and Chief Executive Officer of Dassault Systemes. Revenue In the first quarter of 2004, total revenue increased 4% to (euro)176.2 million as reported and increased 10% in constant currencies, compared to the 2003 first quarter. Both software and services posted year-over-year growth as reported and in constant currencies. Software revenue increased 3% as reported and 9% in constant currencies in the 2004 first quarter in comparison to the first quarter of 2003. Software revenue, accounting for 85% of total revenue, totaled (euro)148.9 million in the first quarter of 2004, compared to (euro)145.1 million in the year-ago quarter. Recurring software revenue represented 56% of total software revenue in the 2004 first quarter. New CATIA and SolidWorks seats licensed in the 2004 first quarter increased 9% to 14,082 seats, compared to 12,917 seats in the 2003 first quarter. Service revenue, representing 15% of total revenue, increased 12% to (euro)27.3 million in the 2004 first quarter, compared to (euro)24.3 million in the year-ago period. Thibault de Tersant, Executive Vice President and CFO of Dassault Systemes, commented, "The Company continued the positive momentum from the second half of 2003, with software revenue showing year-over-year growth for the third quarter in a row. From a regional perspective, we are seeing signs of improvement in Europe slightly earlier than anticipated, with our revenue increasing 4% compared to the year-ago quarter. In the U.S., business activity continued to reflect the more positive trends of 2003, leading to 13% revenue growth in constant currencies for the Americas region in the first quarter. Asia, following on a very strong showing in the fourth quarter, achieved record revenue results in the first quarter with total revenue up 12% as reported and 19% in constant currencies in comparison to the first quarter of 2003. Within the Asian region, our strongest performance came from Japan, with a good level of activity from our PLM businesses and our design-centric segment." PLM performance in the first quarter improved over the year-ago period, led by activity in the aerospace end-market. Process-centric revenue, including PDM revenue, totaled (euro)143.6 million in the 2004 first quarter, an increase of 3% as reported and an increase of 9% in constant currencies. PDM revenue increased 15% as reported and 22% in constant currencies in comparison to the year-ago period. PDM revenues totaled (euro)19.9 million in the 2004 first quarter and represented 11% of total revenue. PDM end-user software revenue totaled US$33.5 million in the first quarter of 2004. PLM orders in the first quarter included customers such as The Boeing Company, Beneteau Group, Meyer Werft Shipyard and Sunten Electric Co. Ltd. Design-centric revenue totaled (euro)32.6 million in the 2004 first quarter, up 7% compared to the 2003 first quarter. Design-centric revenue increased 25% if reported in U.S. dollars, the reporting currency of most of its competitors. In addition to business with existing customers, SolidWorks added over 2,400 new customers in the quarter. Operating Income and Margin, EPS and Financial Position As reported, operating income increased 24% to (euro)42.9 million in the first quarter of 2004 (24.3% operating margin), compared to (euro)34.7 million in the 2003 first quarter (20.5% operating margin). Operating income before acquisition costs increased 18% to (euro)43.5 million in the 2004 first quarter, up sharply from (euro)36.8 million in the 2003 first quarter. The operating margin before acquisition costs increased 3 percentage points to 24.7% in the first quarter of 2004, compared to the year-ago quarter where the operating margin was 21.7% before acquisition costs. Earnings per share increased 20% to (euro)0.24 per diluted share in the first quarter of 2004, up from (euro)0.20 per diluted share in the year-ago first quarter. Earnings per share before acquisition costs increased 19% to (euro)0.25 per diluted share in the 2004 first quarter, up from (euro)0.21 per diluted share in the 2003 first quarter. The strong increase in earnings per share, as reported and before acquisition costs, reflected the growth in revenue and the significant increase in the operating margin over the year-ago quarter. For the first quarter of 2004 net income totaled (euro)28.2 million, up 26% compared to (euro)22.3 million in the 2003 first quarter. Net income before acquisition costs totaled (euro)28.6 million in the 2004 first quarter, up 18% compared to (euro)24.2 million in the year-ago quarter. Dassault Systemes continued to maintain a strong financial position with cash and short-term investments totaling (euro)560.5 million at March 31, 2004, up from (euro)439.7 million at December 31, 2003. Net cash provided by operations was (euro)106.5 million for the first quarter of 2004. Strategy, Technology and Partnerships Mr. Charles stated, "During the first quarter we made excellent progress in realizing key business initiatives. We were very pleased to announce Boeing's decision to develop the 7E7 using our PLM Version 5 software solutions. This will be a broad deployment of all our PLM brands to deliver very significant savings in development time and manufacturing costs and will truly transform the development of aircraft. From a technology perspective, we introduced Version 5 Release 13 (V5R13), our newest release for the PLM market. V5R13 includes a number of advances. In particular, ENOVIA VPM Navigator provides unprecedented data management capabilities from within the familiar environment of CATIA. We continued to pursue our successful diversification strategy, and are excited about our decision to enter the automation market, a new market with significant long-term opportunities for Dassault Systemes, through our recently announced partnership with Schneider Electric." The Boeing Company announced that it has selected Dassault Systemes' latest generation of PLM solutions, including CATIA, ENOVIA, SMARTEAM and DELMIA, as its company-wide product development platform to develop the 7E7 and future projects. Working together, Boeing and DS are creating a virtual collaborative development workspace known as the 7E7 Global Collaboration Environment (GCE), where Boeing and all its partners will design, build and test every aspect of the 7E7 airplane and its manufacturing processes digitally before production begins using the full suite of DS PLM software solutions. DS introduced Version 5 Release 13 (V5R13), "PLM Workspace for Collective Innovation" in March of 2004. CATIA, DELMIA, ENOVIA AND SMARTEAM V5R13 product portfolios bring business value to manufacturers by enabling them and their supply chain to deploy competitive new PLM best practices that reduce development cycles significantly. A major innovation in the V5R13 release is the new ENOVIA VPM Navigator product that enables manufacturers to take maximum advantage of relational design, integrating ENOVIA's virtual product definition into CATIA's easy-to-use design environment. DS and Schneider Electric, the world's Power & Control specialist, entered into a business partnership pursuant to which Schneider Electric will sell DELMIA solutions and develop Consulting and Services for the Automation and Production Engineering markets through a newly formed company called Dextus, fully owned by Schneider Electric. The DELMIA solutions that will be distributed pursuant to this partnership will include a new product line called DELMIA Automation, dedicated to define, control and monitor automated systems. DS and Rand A Technology Corporation, operating as RAND Worldwide, announced plans to create RAND North America, Inc. (Rand Americas), a new joint venture focused on increasing sales of DS PLM software in North America. Subject to the closing of the transaction, Rand Americas will become a subsidiary of Dassault Systemes and will be 60% owned by DS and 40% owned by RAND Worldwide. Charles Edelstenne, Chairman of Dassault Systemes, concluded, "All major product lines and geographies contributed to our revenue growth in the first quarter, which drove strong increases in our operating margin and earnings per share." Business Outlook "We are increasing our revenue growth objective for 2004 to about 8% growth in constant currencies, reflecting higher activity in the first quarter and our new North American joint venture with Rand in PLM," Thibault de Tersant stated. "Due to the strengthening of the U.S. dollar during the first quarter, we think it is appropriate to assume a U.S. dollar to Euro exchange rate of $1.25 per (euro)1.00 for purposes of calculating reported revenue, operating margin and EPS objectives, leading to a reported revenue objective of about (euro)785 million and an EPS objective before acquisition costs of about (euro)1.30 - (euro)1.32 for 2004. Our objective for 2004 is to deliver a stable to slightly increasing operating margin before acquisition costs in comparison to the 29.0% achieved in 2003. Our revenue objective for the second quarter is about (euro)180 - (euro)185 million, based upon a U.S. dollar to Euro exchange rate of $1.25 per (euro)1.00."

The Board of Directors of Dassault Systemes has recommended an increase in the annual cash dividend for the fiscal year ended December 31, 2003 to (euro)0.34 per share (excluding avoir fiscal). The declaration and payment of any cash dividend is subject to approval by shareholders at the Annual Shareholders' Meeting. Endnotes: 1. All comparative figures are given on a year-over-year basis unless specified otherwise. 2. All financial information is unaudited and reported in accordance with U.S. generally accepted accounting principles (U.S. GAAP). Additional financial information is also presented that is not in conformity with U.S. GAAP, in particular the presentation of operating income, operating margin and earnings per share before acquisition costs (acquisition costs are primarily comprised of technology amortization in addition to other acquisition- related costs). The Company has provided in the tables to this press release and on its website http://www.3ds.com/en/investors/presentation.asp reconciliations between U.S. GAAP and non-U.S. GAAP figures. 3. The Company uses constant currency revenue growth to evaluate its financial performance in comparison to prior periods and as a measure of expected growth in planning and setting objectives for future periods. The Company believes this measure is an important indicator of the Company's progress and outlook because it provides a better gauge of the level of change in the business activity as it eliminates any changes arising from currency fluctuations. The Company believes the presentation of this measure is relevant and useful for investors because it allows investors to view revenue growth in a manner similar to the method used by the Company's management, helps improve investors' ability to understand the Company's revenue growth, and makes it easier to compare DS' results with other companies, including competitors, whose reporting currency may be different from DS. Constant currency revenue growth, as calculated by the Company, may not be comparable to similarly titled measures employed by other companies.

In particular, the table presents operating income, operating margin and earnings per share before acquisition costs (acquisition costs are primarily comprised of technology amortization in addition to other acquisition-related costs). The Company uses these non-U.S. GAAP measures, among other things, to evaluate the Company's operating performance and for planning and setting objectives for future periods. The Company believes these non-U.S. GAAP measures are useful to investors because they provide an alternative method for measuring the operating performance of the Company's business by isolating the effect of acquisition costs, which do not impact the underlying business. In addition, these measures are among the primary measures used externally by analysts for purposes of valuation and the comparing operating performance of the Company to other companies in the industry. Since these measures of performance are not calculated in accordance with U.S. GAAP, they should not be considered in isolation of, or as a substitute for, operating income, operating margin and earnings per share including acquisition costs, as an indicator of operating performance.
