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 EUR 0.34 per share (excluding avoir fiscal).

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.
