               Develop Ultra-Efficient Energy-Producing Facility

                    by 30% with Product Lifecycle Management
                           solutions CATIA and ENOVIA

Belle Vernon, Pa., USA and Paris, France - October 24, 2002 - IBM and Dassault
Systemes (Nasdaq: DASTY; Euronext Paris: #13065, DSY.PA) today announced that
CONSOL Energy Inc. (NYSE: CNX) and Farnham & Pfile Construction, Inc. are using
an IBM Product Lifecycle Management Solution to develop and maintain a
computer-controlled coal-processing plant that ranks among the world's most
efficient energy facilities. The solution is based on Dassault Systemes' 3D PLM
CATIA and ENOVIA virtual product design and product data management
applications.

CONSOL Energy, a producer of coal and coalbed methane, and its contractor,
Farnham & Pfile, selected IBM and Dassault Systemes to enhance the coal
processing plant built in Mondsville, West Virginia. The new plant, in operation
since August, is capable of processing up to thirteen million tons of coal a
year, operating twenty-four hours a day, seven days a week.

CONSOL Energy and Farnham & Pfile selected CATIA for its powerful product
development capabilities (design, analysis, and manufacturing), and ENOVIA for
its extensive product data management and global lifecycle collaboration
features. Using CATIA and ENOVIA, the two companies were able to consult each
other and make design modifications in real time during the 16-month
construction period.

"Plant owners and operators constantly strive to maximize productivity while
minimizing maintenance costs and related downtime," said Dan Yanchak, general
manager of preparation services for CONSOL Energy. "At the outset of this
project, we realized that CATIA V5 would be valuable and integral to the ongoing
operation of the plant. With CATIA's digital mock-up and reviewing tools, data
is digitally available and current and, thanks to ENOVIA, always available
online. We also plan to integrate ENOVIA with our SAP system for tight
integration with business processes - an initiative that will keep CONSOL Energy
at the forefront of the energy industry."

"CATIA V5 gave us a big advantage over our competition through cost savings and
process improvement," said Tom Porterfield, vice president of operations at
Farnham & Pfile. "For the new plant, we were able to provide our ceramic pipe
suppliers with detailed drawings that ensured less liability and fewer potential
errors. As a result, supplier costs were reduced by 30 percent and we passed on
those savings. With $5 million worth of piping in a plant, that adds up to
substantial savings."

In the design and construction phases of the new facility, the process flow
sheet, piping, equipment and all processing were performed with CATIA. This
included development of the plant's intelligent piping library, a unique
application that dramatically reduced costs and ensured that designs were
initially accurate. For maintenance, ENOVIA enables engineers to review and
extract real time plant data, including the history of each equipment unit and
its role in the facility, such as the number of hours a pump has been running
and connecting piping and equipment.



                                       2



"IBM has long been committed to providing energy companies with the solutions to
provide sustainable competitive advantages," said David Samuel, general manager,
IBM Energy and Utilities Industry. "By facilitating integration, collaboration,
knowledge management and asset lifecycle management throughout the energy supply
chain, IBM technology and that of our longtime partner, Farnham & Pfile, play a
major role in the development of what will be one of the world's most modern and
efficient coal processing facilities."

"CONSOL Energy and Farnham and Pfile have proven that the same benefits of using
CATIA and ENOVIA in the aerospace, automotive, and shipbuilding domains can be
extended to the plant domain and its business improvements," said Philippe
Forestier, Executive Vice President Sales and Marketing, Dassault Systemes. "We
believe owner-operator-driven 3D PLM is the future of the plant domain and are
proud to be part of a project that will turn this potential into reality."

                    Geometric Software Solutions and Dassault
                 Systemes Announce Original Software Development
                                  Partnership


         Partnership to integrate Feature Recognition technology within
                    CATIA V5 and DELMIA V5 for 3D PLM market


Paris, France, and Mumbai, India - October 24, 2002 - Dassault Systemes (Nasdaq:
DASTY; Euronext Paris: #13065, DSY.PA) and Geometric Software Solutions Co. Ltd.
(Geometric) today announced the signing of an Original Software Development
(OSD) partnership. Under the terms of the agreement, Feature Recognition
technology developed by Geometric will be embedded in the open architecture of
the next Version 5 release of Dassault Systemes' 3D PLM (Product Lifecycle
Management) portfolio.

Feature Recognition technology from Geometric will dramatically reduce design
and manufacturing cycles by enabling mechanical and manufacturing products in
CATIA and DELMIA V5 to automatically recognize features from any legacy 3D
model. CATIA Feature Recognition technology will operate on the geometry of any
3D solid and automatically identify prismatic and transition features such as
fillets and chamfers for design applications, as well as prismatic machining
features for manufacturing applications.

"We are very excited and pleased with this new partnership with Dassault
Systemes," said Manu Parpia, managing director, Geometric. It adds to
Geometric's contribution to the Dassault Systemes ecosystem while demonstrating
our success in building world-class components and technologies."

"Integrating Geometric's Feature Recognition technology into CATIA and DELMIA V5
design and manufacturing products will provide our customers with powerful tools
for fast design modification, manufacturing planning, and NC (Numerical
Control)," said Jacques Leveille, vice president of CATIA Research and
Development at Dassault Systemes. "That results in reduced development cycles
for both their internal business processes and supply chain management."

"Feature Recognition is an excellent example of how research ideas originating
in India's premium technology institutes can be converted into world-class
products," said Anil Risbud, chief technology officer, Geometric. "With this
partnership, we look forward to building a solution with key innovative
differentiators thanks to the CAA V5 open architecture."

Feature Recognition is a patent-pending technology from Geometric and
incorporates over ten years of research. Part feature recognition in CATIA will
enable quick design modification of the geometry of 3D solids and enable its
intelligent reuse in downstream and knowledge-based applications. Prismatic
machining preparation will generate a view of the manufacturing features for any
design model and help leverage the design-to-manufacturing path and the
automation of manufacturing processes.

The new partnership strengthens a long history of cooperation between Geometric
and Dassault Systemes. Earlier this year, the two companies formed a joint
venture in which Geometric provides software development services for Dassault
Systemes, and later announced a worldwide Consulting and Services partnership
for Dassault Systemes' 3D PLM software.

                                       ###
