                     Enterprise Transaction Model, SMARTSCOR
                From Dassault Systemes and StreamlineSCM Simplify
                      Complexities Of Today's Supply Chains

              Revolutionary Services Offering Makes SCOR Model Easy
          To Implement Via Combination of StreamlineSCM's SCOR Database
                      And Dassault Systemes' PLM Portfolio


Atlanta, Ga. - April 7, 2003 - Dassault Systemes (Nasdaq: DASTY; Euronext Paris:
#13065, DSY.PA), the world's leading provider of product lifecycle management
(PLM) solutions, and StreamlineSCM, LLC, a privately held, supply chain
management implementation and consulting firm, today announced the two companies
have teamed up to develop and market the Enterprise Transaction Model (ETM), a
revolutionary services offering based on a jointly-developed solution called
SMARTSCOR. Announced and demonstrated for the first time at Supply Chain World
Conference & Exhibition 2003 in Atlanta, Ga., ETM and SMARTSCOR enable companies
to easily visualize, analyze, and reduce complexities in today's sophisticated
global supply chain environments.

Originally developed for companies trying to implement the SCOR model, SMARTSCOR
consists of supply chain management tools and technologies supported by
world-class methodology, software, and infrastructure. ETM is based on the
supply chain operations reference, or SCOR, model developed and promoted by
Supply-Chain Council, Inc., the industry's leading advocacy group. SMARTSCOR
enables users to exploit intelligence surrounding a company's operating
processes and modeling capabilities, make higher-quality business decisions, and
more effectively apply important corporate knowledge. The offering is expandable
and scalable, depending on a firm's specific needs, and includes workflow
management and seamless integration with existing enterprise systems, such as
enterprise resource planning (ERP), customer relationship management (CRM), and
PLM solutions.

"Business today is extraordinarily complex and full of constant process
variation, which makes it difficult for companies to efficiently manage critical
supply chain operations necessary for success," said Bruce Van Nus, vice
president of Dassault Systemes Services and president of Dassault Systemes, Inc.
"ETM provides companies with a unified reference model that allows them to
visualize, navigate, and optimize these essential processes, thereby eliminating
many of the inherent complexities of the supply chain framework. In doing so,
corporations are able to analyze and understand supply chain weaknesses, and
then take corrective action which results in cost reductions, decreased risk,
and higher performance."

Dassault Systemes, StreamlineSCM Introduce Enterprise Transaction Model and
SMARTSCOR 2-2-2


"Although the SCOR model has been effective at addressing a myriad of supply
chain management issues, ETM goes well beyond SCOR to present a graphical
representation of a company's operating processes, and the means for immediately
analyzing and fixing pressing problems, said Greg Peck, general manager of
StreamlineSCM, LLC. "ETM is more than simply a combination of technologies for
effective supply chain management. It is a viable business methodology that
empowers companies to take control of these processes, make more informed
decisions, and improve overall corporate performance."

The SMARTSCOR solution and ETM offering is comprised of a number of
sophisticated technologies for managing intricate supply chain infrastructures,
including:

o    SMARTSCOR, a set of customized SCOR tools based on Dassault Systemes'
     SMARTEAM(TM) PLM Solutions, and specifically modified for a particular
     customer environment.
o    Training, analysis methodology, and customized software solutions based on
     the SCOR model.
o    Dassault Systemes' PLM reference framework.
o    Integration with existing customer enterprise systems, including CRM, ERP,
     SCM, and PLM.
o    Multiple configurations, depending on a customer's individual needs and
     issues.
o    System implementation and support.

FOR IMMEDIATE RELEASE
---------------------

                    Dassault Systemes Is The Fastest Growing
                       Company In Product Data Management
                              According to CIMdata

                   Foremost Global Developer of PLM Solutions
                   Increased PDM Revenue By 25 Percent In 2002


Paris, France -- April 7, 2003 -- Dassault Systemes (Nasdaq: DASTY; Euronext
Paris: #13065, DSY.PA), the world's leading developer of product lifecycle
management (PLM) solutions, today announced it has become the fastest growing
company in the product data management (PDM) segment of the PLM market, based on
market research data from prominent industry analyst firm CIMdata, Inc., and
2002 financial performance figures released by PDM vendors.

"Despite the continued global slowdown in investments throughout 2002, Dassault
Systemes and its partner IBM had a solid year in PLM by achieving
industry-leading growth of over 25% in collaborative Product Definition
management (cPDm) new license sales," said Ken Amann, director of research at
CIMdata, Inc., a leading PLM research and advisory firm. "Among the leading cPDm
providers, only Dassault Systemes delivered year-over-year growth in 2002, while
its competitors saw their respective sales remain flat, or decline, in
comparison to 2001 figures."

"Without question, 2002 was a breakout year for Dassault Systemes' PDM business,
as the company outperformed top competitors by a wide margin in this important
market segment," said Bernard Charles, president and CEO of Dassault Systemes.
"The combination of Dassault Systemes' ENOVIA and SMARTEAM offerings, serving as
the product knowledge and process infrastructure, constitutes a cohesive PDM
solution of unmatched breadth and scope. The wide adoption of these offerings by
customers, within the overall Dassault Systemes PLM environment, is a resounding
endorsement of the company's mission to deliver on the promise of PLM throughout
and across the extended enterprise. With strong fourth quarter finishes by both
ENOVIA and SMARTEAM, these impressive results illustrate the success of the
company's PLM strategy, and its ability to provide customers with robust PDM
solutions that address and respond to complex business needs."

According to the company's 2002 financial results, Dassault Systemes' overall
PDM revenue rose 33% in the fourth quarter to (euro)30.9 million, up from
(euro)23.3 million during the same period a year ago. For the year, PDM revenue,
on a stand-alone basis, increased 25% to (euro)82.7 million, up from (euro)65.9
million in 2001. This revenue is comprised of sales of the company's overall PDM
offering, currently consisting of the ENOVIA and SMARTEAM branded solutions.
