[DASSAULT SYSTEMES DELMIA LOGO]


                    Bosch Targets "Quantum Leap in Production
                     Planning" with DELMIA Process Engineer

          Automotive supplier adopts digital factory solution to align
                 systems with auto manufacturer DaimlerChrysler

Fellbach, Germany, and Auburn Hills Mich., USA - July 31, 2003 - Delmia Corp., a
Dassault Systemes company (Nasdaq: DASTY: Euronext Paris: #13065, DSY.PA), today
announced that Bosch, a major automotive supplier, has invested in DELMIA
process planning solutions to meet the requirements outlined for
DaimlerChrysler's "Digital Factory" initiative. Bosch celebrated the
introduction of its Cooperative Engineering program (COPE), with
DELMIA(TM)Process Engineer at its core, as a "quantum leap in production
planning". The COPE program offers computer-aided production planning in
parallel with product development.

Benefits of simulated production planning include the identification and
elimination of potential problems in a virtual environment, before they become
real and incur damage and costs. DELMIA Process Engineer is compliant with the
essential principles of the Bosch Production System. Standardized planning has
proven to help identify weaknesses in the concept and design of production
manufacturing facilities early in the process, saving both time and money.

Early results of DaimlerChrysler's efforts toward the Digital Factory have shown
cost reductions of up to 30 percent in some areas of vehicle planning.
DaimlerChrysler recognizes the value of DELMIA's role and is intent on
developing its supplier base to pursue this initiative. The true potential of
all cost reduction opportunities will be realized only when the entire process
chain and all involved partners are integrated into the system.

"Involvement in all product lifecycle processes at an early stage with
guaranteed global data exchange will increasingly affect the quality of planning
and production processes," said Raimund Menges, CEO, Delmia GmbH. "There is no
doubt that tools such as COPE and DELMIA Process Engineer will become firmly
entrenched as key technologies - particularly in the automotive industry - on
the way to a comprehensive Digital Factory. Suppliers aiming to remain
competitive will have to prepare to handle this issue."

DELMIA Process Engineer provides individual methods for production planning
through seamless sharing of information via a single integrated data model
referred to as the DELMIA PPR Hub for Manufacturing. Product design, logistics
planning, cost estimates during product development, workplace design, time
management and flow simulation are all accessible and updated in real time in
the PPR Hub.

As processes become more complex with product variety and the number of model
variants increasing, it is critical that all links in the product lifecycle
chain - starting with the very first idea - be of one accord. All sequences must
be digitally reproduced in CAD with the common data then used to virtually
simulate production concurrently with product development, prior to any real
part being produced.

                                       4





DELMIA's series of successes with automotive manufacturers such as
DaimlerChrysler, Toyota, and General Motors, is now followed by numerous
projects with suppliers such as Bosch. The close connection between CATIA(R) --
the CAD world market leader - and DELMIA -- with its extensive experience in
assembly optimization, has made the software an ideal choice for many companies.

                                       ###

About Bosch

Bosch is a worldwide name in a large number of areas. These include, for
example, electrical and electronic automotive technology, power tools,
thermotechnology, household appliances, security systems and broadband networks
as well as automation technology and packaging technology.


The small "workshop for precision mechanics and electrical engineering" which
Robert Bosch founded in Stuttgart in 1886, and which soon specialized in
ignition systems for motor vehicles and engines of all kinds, has now become the
Bosch group, which is active worldwide and is one of the largest companies in
the Federal Republic of Germany in terms of turnover, which amounted to (euro)
35 billion in 2002.


The international orientation of Bosch started at the end of the 19th century.
The first agencies were set up abroad at that time. At the beginning of 2003,
the Bosch Group had approx. 224,000 employees, more than half of which were
outside Germany. The company has around 250 subsidiaries and associated
companies in over 50 countries. A total of 236 manufacturing sites, 179 of which
are located outside Germany, support the international activities. A key part
here is played by the efficient sales and customer service organization with
9,000 Bosch Service centers with approximately 60,000 employees in 130
countries.

                  Evernham Motorsports Takes the Checkered Flag
                   with Product Lifecycle Management Solutions
                         from IBM and Dassault Systemes

             Leading NASCAR team will use PLM to accelerate design,
                construction and maintenance of faster race cars


Statesville, North Carolina and Paris, France - July 31st, 2003 - IBM and
Dassault Systemes (Nasdaq: DASTY, Euronext Paris: #13065, DSY.PA) today
announced the signing of a contract for Product Lifecycle Management (PLM)
solutions with Evernham Motorsports LLC, a leading NASCAR Winston Cup Series
race team.

IBM PLM Solutions, with CATIA(R) V5 for collaborative product development and
SMARTEAM(R) for collaborative lifecycle management from Dassault Systemes, will
allow Evernham Motorsports to develop high performance race cars through virtual
testing rather than building costly, full-scale physical prototypes.

Additionally, Evernham Motorsports will integrate the new PLM platform with its
own inventory and maintenance programs. By linking with PLM Solutions from IBM
and Dassault Systemes, Evernham engineers will make design modifications while
accessing car building-material information, field usage statistics, and
inventory all in one streamlined view, saving precious hours between races. This
will allow Evernham Motorsports to gain efficiencies and focus more time on
innovative ways to build faster, safer competition vehicles.

"With 38 races per season and constant changes and revisions to our race cars,
our down time has to be undetectable," said Dr. Eric Warren, Technical Director,
Evernham Motorsports. "We want to streamline our approach and coordinate
everything from manufacturing to maintenance. IBM PLM Solutions with Dassault
Systemes software have given us the tools to organize the entire flow of product
data."

"Each season, NASCAR teams must develop new, complex parts and assemblies, all
the while complying with strict stock car racing technical and regulatory
specifications," said Marcelo Lemos, President, Dassault Systemes of America.
"CATIA's exceptional collaborative product definition capabilities coupled with
SMARTEAM's leading-edge data management features will give Evernham Motorsports
the accelerated advantage required to build innovative, winning race cars."

The hardware platform chosen for the new PLM system is comprised of IBM M Pro
and Z Pro IntelliStations and an IBM X Series eServer.

                                       ###
