(the "Company") is furnishing under cover of Form 6-K, two press releases dated February 18, 2003, the first announcing the signing of a CAA V5 (Component Application Architecture) strategic development agreement under which ESI Group will develop and sell its next generation solutions for Virtual Prototyping, Manufacturing and Environment using V5 middleware, the second announcing the signing of a million-dollar Product Lifecycle Management (PLM) solution contract with ENAER, Chile's national aeronautical company. Dassault Systemes and ESI Group Join Forces to Deliver Next- Generation Virtual Prototyping and Manufacturing Solutions within V5 New ESI Group CAA V5 based products will take major step toward realistic PLM simulation in the "Virtual Try-Out Space" Paris, France - February 18, 2003 - Dassault Systemes (Nasdaq: DASTY; Euronext Paris: #13065, DSY.PA) and ESI Group (Euronext Paris: #6584) today announced the signing of a CAA V5 (Component Application Architecture) strategic development agreement under which ESI Group will develop and sell its next generation solutions for Virtual Prototyping, Manufacturing and Environment using V5 middleware. As a result of this partnership, ESI Group will first focus on delivering within V5, multi-physics realistic simulation solutions for crashworthiness and stamping processes. ESI Group is a world-leading provider of digital simulation software for prototype and manufacturing process engineering that takes into account the physics of materials critical for crash, safety, vibro-acoustics, stamping, casting, welding, flow and electromagnetics simulation. Under the terms of the agreement, ESI Group joins Dassault Systemes' Software Community Program as a CAA V5 Gold Software Partner. ESI Group will benefit from the V5 environment to deploy its "Virtual Try-Out Space" (VTOS) strategy, a virtual engineering global solution that simulates manufacturing processes and the real-life performance of industrial products subjected to a wide range of phenomena in applied physics and mechanics. The availability of these advanced capabilities in the V5 product definition and associative environment will optimize product engineering, improve product performance and quality, and reduce design cycles. "We are confident that Dassault Systemes' CAA V5 can guarantee the best environment to deliver our integrated Virtual Try-Out Space and its unique virtual manufacturing solution to the PLM marketplace. ESI Group's extended product portfolio and V5 based solutions will enable on-line decision making by creating the ideal platform for product and process resource optimization. Chaining manufacturing processes and prototype testing simulation will turn the current digital mock-up into a realistic physical digital model, reducing time-consuming and expensive hardware prototyping", says Alain de Rouvray, chairman and CEO of ESI Group. "ESI Group's endorsement of V5 is a new step forward in delivering the best realistic simulation portfolio available for all industries," said Dominique Florack, Executive vice president Research and Development, Dassault Systemes. "In addition, I believe that ESI Group's innovative approach to multi-physics simulation complements very well existing V5 applications from Dassault Systemes and our strategic partners."

The IBM PLM solution, with CATIA(R) and SMARTEAM(R) developed by Dassault Systemes, will enable ENAER to standardize its entire product development platform, while realizing significant cost reductions. ENAER will be the first company in the Latin American aerospace supplier market to possess this leading-edge technology, which will enable it to pursue market opportunities at a global level. ENAER will be able to offer other aerospace manufacturers solutions for the conception, design and manufacture of aircraft parts and structures. The company will also be able to enhance its end-to-end internal production chain by tying together its design, engineering and manufacturing processes, as well as linking suppliers and customers. Finally, ENAER will be able to optimize the design of its own products and increase its maintenance services for military and commercial aircraft. "ENAER wants to be a leader in the aeronautical industry, and therefore we have signed an agreement with IBM that provides us with best business solutions in order to support our growth plans," said Alfredo Guzman, executive director at ENAER. "Thus, we are also betting on research and development as a company's strategic decision, in order to provide added value to these products that are manufactured in Chile." Luis Siles, IBM Chile General Manager said "This alliance is a milestone for the domestic and Latin American aeronautical industries and opens up new horizons for equivalent industries, and is a great example of how IBM helps customers transform into on demand businesses by enabling them to become more highly responsive, focused, resilient and variable in fiercely competitive marketplaces." "CATIA is the de facto industry standard in the aerospace sector," said Marcelo Lemos, president of Dassault Systemes of America. "Combined with SMARTEAM's cutting-edge collaborative product data management capabilities, it will help ENAER compete in the international aerospace market, as well as achieve its mission to provide superior products to the Chilean Air Force and contribute to Chile's national aeronautical development." In order to implement this solution, IBM will be supported by Dassault Systemes of America and also by Cardix S.A. of Argentina, IBM PLM Business Partner, for installation, training, best practices and post-implementation support. ### About ENAER ENAER has more than 70 years of experience in the production and assembly of aeronautical parts and is the only aircraft manufacturer in Chile.
