A press release dated September 29, 2003 announcing that Gehry Technologies has
formed a business partnership with IBM and Dassault Systemes.


            Frank Gehry Joins Forces with IBM and Dassault Systemes
        to Bring Their PLM Version 5 Solutions to the Building Industry

                      Gehry Technologies to address broader
                           construction industry needs

Los Angeles, USA and Paris, France - September 29, 2003 - Gehry Technologies(R),
an independent company created by Gehry Partners' research group, has formed a
business partnership with IBM and Dassault Systemes (NASDAQ: DASTY; Euronext
Paris: #13065, DSY.PA).

Gehry Technologies has received accreditation as a certified IBM Business
Partner selling and servicing IBM and Dassault Systemes' CATIA(R), ENOVIA(TM)
and SMARTEAM(R) Product Lifecycle Management (PLM) software, and IBM hardware,
including IntelliStation workstations. Gehry Technologies is also a member of
the Dassault Systemes Education Partner Program, a global initiative to sustain
world class, educated PLM professionals.

By enabling architects, engineers, contractors, fabricators and suppliers to
focus on their core competencies, PLM technology from IBM and Dassault Systemes
will allow them to collaborate more efficiently and will transform the way they
develop projects with clients. Similar to its revolutionizing effect on the
automotive and aerospace industries, PLM will also have a significant impact on
project design, procurement, and execution by providing better cost
predictability, reduced development time, and increased innovation.

Throughout the last 14 years of his career, Frank Gehry and his partner Jim
Glymph have been strong champions of PLM technologies from IBM and Dassault
Systemes, including CATIA V5, for collaborative product development in 3D. They
have pioneered the application of these technologies on projects throughout
Europe and North America. The success of this vision can be seen in Frank
Gehry's completed works such as the Guggenheim Museum in Bilbao, Spain, the
Experience Music Project in Seattle, and the Walt Disney Concert Hall in Los

Under Jim Glymph's stewardship and his R&D group, Gehry Partners has accelerated
the use of advanced computing tools to promote collaboration between designers
and craftsmen. The broad international base of Frank Gehry projects has enabled
the R&D group and its partners to gain a unique insight into the design and
construction processes used for architectural projects around the world.
Knowledge of these contracting and managing projects facilitates integration
with new processes made possible by advanced computing.

"We are aware of the challenges we face in introducing new processes to the
building design and construction industry," said Jim Glymph, CEO, Gehry
Technologies. "This is an industry that does not have the cohesion of the
manufacturing sector, and it must deal with processes, procedures, regulations,
and even traditions of practice, that differ greatly from region to region,
nationally and internationally. We are leveraging our international experience
by identifying best practices and procedures that can use Gehry Technologies
computing solutions to advantage."

"Frank Gehry is one of the most influential architects of our time. Using IBM
PLM Solutions, he has revolutionized the world of modern architecture with
technologically-sophisticated masterpieces, including the Guggenheim Museum in
Bilbao, Spain," said Scott Hopkins, general manager, IBM Product Lifecycle
Management. "We share Mr. Gehry's objective to give the entire building industry
the power to create innovative structures far beyond what was possible in the
past. PLM technology, backed by Gehry's expertise, will have a dramatic impact
on the architectural landscape of the future."

"It is a great satisfaction to see that CATIA and our V5 PLM platform will play
a critical role in modernizing the design and construction of buildings," said
Bernard Charles, president and CEO, Dassault Systemes. "It is a fantastic
transformation launched by one of the most prestigious architects of our time.
Frank Gehry proved that our PLM technology enables profound improvements in
building design, construction and contractual processes. This alliance confirms
the dynamic of the adoption of our V5 PLM platform in multiple sectors."

The R&D group of Gehry Partners formed Gehry Technologies with the intent of
introducing the building design and construction industry to software solutions
and new project delivery processes that have been made possible by these
emerging technologies. The group encourages the building industry to examine and
challenge traditional project delivery processes to achieve the advances made
possible by these technologies.
