                         Dassault Systemes Acquires KTI

               Acquisition of Knowledge-Based pioneer complements
                  Dassault Systemes' V5 Knowledgeware solutions
                             and consulting services

Suresnes, France - November 20, 2002 - Dassault Systemes (Euronext Paris #
13065, DSY.PA, Nasdaq: DASTY) today announced the acquisition of Knowledge
Technologies International (KTI) in an all-cash transaction. Through its
consulting expertise and ICAD software, KTI has become the recognized leader in
Knowledge-based engineering (KBE) solutions for the capture and automation of
proprietary customer design and manufacturing processes, particularly in the
aerospace and automotive industries. Examples of KBE use include the automatic
design of the thousands of standard parts in aircraft wings or electrical system
components in automobiles.

The acquisition of KTI complements Dassault Systemes' existing V5 Knowledgeware
solutions and places the company in a leadership position across the full range
of KBE practices. KBE practices are divided into three domains that include:
generic applications; industry specific solutions; and customer proprietary
process automation. KTI is the leader in customer proprietary process automation
while Dassault Systemes is the leader in generic applications and industry
specific solutions.

Integrating the development, capture and reuse of a customer's know how is an
essential ingredient for successful PLM implementation. Beyond the "what" of
products (the components), Knowledge-based solutions capture and manage the
"why" and "how" (the collective knowledge). Combining KTI's KBE consulting
competence with Dassault Systemes industry-processes expertise creates an
unrivaled services offering in the PLM industry that will make Knowledge-based
engineering a reality for all customers.

"Our 3D PLM customers are reaching unprecedented levels of productivity due
largely to the next generation Knowledge-based technology we place at the core
of our V5 solutions," said Dominique Florack, executive vice president Research
and Development, Dassault Systemes. "Over the past 20 years, KTI has developed a
unique understanding and expertise in the development and application of
Knowledge-based solutions and this acquisition complements our existing services
organization to deploy breakthrough PLM solutions for all of our customers."

"This acquisition will deliver tremendous value to our existing ICAD customers,"
said Dr. Prasanna Katragadda, Vice President Research and Development, KTI. "It
immediately secures their investments and provides a roadmap to further expand
the management of their Knowledge-based Engineering activities beyond the design
and manufacturing stages and into the rest of their product's lifecycle
management."

 "Over the past seven years, Airbus, with the support of KTI, has secured
significant returns through Knowledge-based engineering, enabling automation,
integration and innovation of key processes," said S.E. Allwright, head of
Knowledge Based Engineering, Airbus. "With the acquisition of KTI by Dassault
Systemes, Airbus expects to immediately benefit from synergies in the
development of Knowledge-based solutions and provision of services. This will
enable Airbus to accelerate and broaden our implementation of KBE across our
complete set of product lifecycle processes."

BMW, DaimlerChrysler, PSA, Bombardier, and SAAB as well as many laser shops.

"LaserCUT on CATIA Version 4 was our first step in the world of 3D CAD and
5-axis offline programming," said Jim Abbott, Novi, CNC Center Inc. "Today we
can say that LaserCUT is one of the main reasons that we can offer efficient and
high quality laser cutting services. We are happy to see that this pragmatic and
efficient solution will be available on a new platform in order to keep
improving our current processes."

"Three years ago, we replaced our previous solution by LaserCUT due to its
leading functionality and due to the CATIA integration, said Ulrich Loffelhardt,
head of Manufacturing Applications at Daimler Chrysler Germany. "With the
V5-platform and its associative process chain, we see new opportunities to
integrate FasTRIM with DaimlerChrysler's digital manufacturing concept."

FasTRIM provides complete offline programming functionalities such as intuitive
programming features, powerful simulation capacity, automatic path generation,
best fit calibration to match machine home with part origin, automatic fixture
builder and reverse engineering. Thanks to its DELMIA V5 integration and
cooperation with leading machine suppliers, FasTRIM currently supports all
well-known 5-axis machine tools (including Trumpf, Prima, Mazak, and NTC) and
will support robot cells. CENIT will deliver an end-to-end solution by selling
its integrated FasTRIM add-on to the DELMIA FasTRIM configuration and related
services for a machine tool implementation kit.

"The common V5 platform for CATIA and DELMIA, allows us to use best-in-class
technology for all components of the FasTRIM solution such as geometry creation
and access, offline programming, and simulation," said Peter Hinkel,
e-Manufacturing Manager, CENIT. "The CAA V5 experience we acquired by developing
a CATIA V5 integrated product (CUT4AXES) allowed us to seamlessly begin FasTRIM
development as a DELMIA integrated product. The V5 platform enables us to
develop our products very efficiently and provide our customers with a high
quality, 3D PLM integrated solution."

"CAA V5, the open middleware for 3D PLM, provides a unique competitive advantage
to both our customers and our software partners," said Stephane Declee, vice
president



                                        4


Research and Development Strategy, Dassault Systemes. "By leveraging the V5
architecture in a single development effort, CENIT is able to provide the

                    TOYOTA INDUSTRIES CORPORATION Cuts Costs
                    and Development Time with PLM Solutions
                         from IBM and Dassault Systemes

    Leading industrial vehicle manufacturer reduces its new "High Pick Lift"
        forklift development costs by 53% and development cycles by 44%

    Forklift design wins prestigious 'Japan Society of Industrial Machinery
                             Manufacturer's Award'


Tokyo, Japan and Paris, France - November 20, 2002 - TOYOTA INDUSTRIES
CORPORATION (TICO), a world leader in the industrial vehicle market, IBM and
Dassault Systemes (Nasdaq: DASTY; Euronext Paris: #13065, DSY.PA) today
announced that TICO has significantly reduced development costs and cycles of
its High Pick Lift forklift using IBM Product Lifecycle Management (PLM)
solutions, including CATIA V5 developed by Dassault Systemes. Dassault Systemes
also announced that TICO is currently using its DELMIA solution for the
development, simulation and management in real-time of TICO's factory tools and
production processes.

TICO began using PLM solutions from IBM and Dassault Systemes in late 2000. The
solutions were implemented to develop forklifts as part of IT Propulsion, a
company-wide program designed to improve business reactivity through the use of
3D data and improved information management and sharing. CATIA V5 Knowledgeware
technology helped TICO achieve these goals by allowing the company to
automatically combine standard design definitions with customer-specific
functional requirements. This presents a major advantage in forklift
development, commonly dictated by the built-to-order model consisting of many
variations and options.

Using the collaborative functions of IBM PLM solutions, TICO has been able to
integrate its 3D forklift product information with its manufacturing processes
and resources and, design and simulate virtual factories using Dassault
Systemes' DELMIA digital manufacturing solution.

In order to accelerate further global collaboration, TICO will deploy IBM and
Dassault Systemes' SMARTEAM solution to connect selected development sites
worldwide. TICO will integrate its 3D models, 2D drawings, technical
documentation and BOM (Bill of Materials) using SMARTEAM, which provides
powerful collaborative product development and lifecycle management solutions.

"Our high-level product development know-how combined with IBM and Dassault
Systemes' pioneering PLM solutions have brought tremendous synergies to the
development of the High Pick Lift," said Kimpei Mitsuya, director and member of
the board, Global IT Division, TICO. "We achieved our original targets both by
shortening the High Pick Lift development period from 18 to ten months and by
reducing development costs by 53%. In addition, this product won the 'Japan
Society of Industrial Machinery Manufacturer's Award' for its gentle curved
design which was achieved thanks to CATIA V5's 3D design functionalities."

"TICO is a real-life example of how companies can implement a full PLM strategy
using the powerful combination of applications in the IBM PLM portfolio along
with proven PLM methodologies to gain major improvements in their industrial
processes. TICO has adopted PLM solutions to integrate the complex design,
engineering, and manufacturing technologies



                                        6


used in forklift production across its extended enterprise," said Raoul Van
Engelshoven, vice president, IBM Product Lifecycle Management Asia Pacific. "Not
only does that meet the goal of TICO's IT Propulsion project for improved
product quality and business responsiveness, but it also translates into
concrete time and costs savings, both immediately and in the years to come."

"TICO's success is a perfect example of how companies in the Fabrication and
Assembly market can increase their competitiveness by using collaborative 3D
product development solutions across all stages of the product lifecycle," said
Etienne Droit, executive vice president sales and marketing, Dassault Systemes.
"Dassault Systemes' 3D PLM technologies enabled a world leader in the forklift
market to turn its implicit know-how into explicit knowledge, and in doing so,
helped TICO improve its ability to innovate, cut costs, and shorten development
time."

In order to establish paperless communication with its suppliers by the end of
2004, TICO has established a Supplier Support Center at its Takahama Plant in
the Aichi Prefecture. The center is equipped with a collaboration room, where
suppliers can hold digital design review meetings, as well as 3D CAD rooms for
CATIA V5 training.
