Dassault Systemes S.A. (the "Company") is furnishing under cover of Form 6-K, a
press release dated November 21, 2002, announcing the successful implementation
of an IBM Product Lifecycle Management (PLM) solution based on the Company's
products, CATIA V5 and SMARTEAM, which was deployed across NSC Schlumberger's
fiber-to-yarn division to develop new textile machines.




                                                                               1



                    NSC Schlumberger Develops Better Textile
              Machines with Product Lifecycle Management Solutions
                         from IBM and Dassault Systemes

          PLM Solutions CATIA V5 and SMARTEAM improve development time
      after only 18 months - PLM strategy to be extended throughout entire
                                   enterprise


Paris and Guebwiller, France - November 21, 2002 - NSC Schlumberger, IBM, and
Dassault Systemes (NASDAQ: DASTY; Euronext Paris: #13065, DSY.PA) today
announced the successful implementation of an IBM Product Lifecycle Management
(PLM) solution based on Dassault Systemes' products, CATIA V5 and SMARTEAM. The
PLM solution was deployed across NSC Schlumberger's fiber-to-yarn division 18
months ago in order to develop new textile machines. The project, executed in
three factories in France, involved the design, marketing and maintenance
divisions. Schlumberger expects product development time to improve by 25%. As a
result of this successful implementation, the company has decided to extend the
IBM PLM solution to the other four subsidiaries of NSC Group.

The implementation of CATIA V5 and SMARTEAM at NSC Schlumberger has created
concrete business value and rapid return on the PLM platform investment. This is
exemplified by the elimination of the production of three costly prototypes for
each new project. With the PLM platform in place, NSC now only produces one
final prototype. The PLM platform has also allowed NSC to rapidly test various
models in 3D, including new components and new mechanisms. In addition,
maintenance is greatly improved, making NSC far more competitive by avoiding
costly errors frequently involved in the maintenance phase. Overall, the
implementation of the IBM PLM platform coupled with the support of IBM Business
Consulting Services (BCS) will result in a 25% improvement in development time
at NSC.

NSC has relied upon the support and implementation services from IBM BCS to
determine the criteria for the new design platform and an appropriate product
development strategy. IBM started by evaluating NSC's production environment and
working processes and adapting CATIA V5 to NSC's business requirements. NSC
Schlumberger and IBM, working with Dassault Systemes, developed new
methodologies to create a true PLM strategy tailored to NSC's specific industry
needs by sharing common experiences. After creating new design scenarios and new
collaborative working methods, IBM BCS deployed the solutions, integrated the
tools, and provided training and educational support for the product-related
functions.

NSC fiber-to-yarn designs and manufactures a wide range of industrial machinery
that produces yarn from natural or synthetic fibers. The division boasts a
market share of over 50%. Although many of its competitors are moving operations
to the Asia-Pacific region to decrease costs, NSC chose to become more
competitive by creating more efficient textile machines and improving the
product life cycle, especially concerning maintenance.

NSC evaluated several solutions and partners, and chose CATIA V5 for its ease of
use and ability to foster creativity and innovation in the design process. They
chose to complement the virtual design application with the product data
management application SMARTEAM, also part of the IBM PLM product line, for its
exceptional flexibility and ease of use in their



                                                                               2


environment. The two solutions met the many prerequisites established during the
evaluation phase by NSC.

"The results were beyond what we had hoped for," said Gerard Gaire, director of
Research and Development, NSC Schlumberger. "Our goal is to achieve similar
results across our other four subsidiaries, using collaborative work processes
and managing the product lifecycle from the budding idea through to maintenance.
With the help of IBM, we are exploiting powerful PLM solutions and
methodologies, essential to growing our market share."

"By implementing IBM PLM solutions for product development and product data
management, and complementing this PLM platform with collaborative
methodologies, NSC Schlumberger is setting an example of how e-business should
be done. And after only 18 months, the investment is paying off. We salute NSC
Schlumberger for their winning vision and will continue to help them reap the
many business benefits IBM PLM solutions offers." said Klaus Schaeffer, vice
president EMEA, IBM Product Lifecycle Management.

"NSC Schlumberger's decision to use CATIA V5 after performing extensive
comparative testing illustrates CATIA's superior performance as the world's
leading 3D Product Lifecycle Management solution for fabrication and assembly
industries," said Philippe Forestier, executive vice president of Sales and
Marketing at Dassault Systemes. "NSC's choice of SMARTEAM to complement CATIA V5
underscores the seamless integration between the two 3D PLM solutions, giving
NSC the capability to manage highly complex processes and data with ease,
efficiency and speed."
