VELIZY-VILLACOUBLAY, France — November 24, 2010 — Dassault Systèmes (Euronext Paris: #13065, DSY.PA), a world leader in 3D and Product Lifecycle Management (PLM) solutions, was informed today by Daimler A.G of its decision to select CAD from Siemens.

This decision came as a surprise to Dassault Systèmes as no CATIA V6 evaluation has been performed by Daimler A.G. We were informed by Daimler A.G. that, as CAD application portfolio was not its priority, its decision was based upon CAD integration in its home grown PDM system “Smaragd”. V6 openness to other PDM systems is part of PLM V6R2011x, which was announced yesterday.

On September 20, 2010, Daimler A. G. renewed its CATIA contract with Dassault Systèmes for five years. In addition to CATIA, Daimler A.G. uses the Company’s DELMIA, ENOVIA, SIMULIA, and 3DVIA brands.  At this stage, we have no information as to which CATIA specialized applications would be replaced and which ones will have to remain in use.
