Charles Edelstenne, Chairman and Chief Executive Officer of Dassault Systemes, commented, "Third quarter results came in very much as anticipated. This is due to the solid contribution of each of our product lines and the strong visibility provided by our business model. "

Bernard Charles, President of Dassault Systemes, stated, "Our expanded Strategic Partnership with IBM, which we announced October 5, is a significant new step toward delivering and implementing e-business solutions to address the product creation and product life pipeline for both Global and Medium to Small companies in multiple industries. In addition, through a reorganization of the IBM sales force by market segment in an enhanced relationship with IBM Global Services, we will focus on Digital Enterprise deployment projects.

"During the quarter, the Company introduced ENOVIA Portfolio, which is organized in five foundations: 3D Portal, Life Cycle Applications, Product Processes and Resources Hub, Enterprise Architecture, and Rapid Application Development. ENOVIA is uniquely positioned to serve the Virtual Enterprise requirements (B-to-B) as well as to provide Digital Product availability to consumers (B-to-C). It leverages the Digital Product and Process Definition across all phases of the Product Life cycle. Through the integration of CATIA, ENOVIA and DENEB, our customers benefit from the largest and most comprehensive product portfolio to implement their Digital Enterprise model."

Thibault de Tersant, Executive Vice President, said, "Notwithstanding this near term period of expected slower revenue growth, we are continuing to make significant investments in research and development and marketing and sales, to seize the enormous Digital Enterprise opportunity we see in front of us."
