Ciba Specialty Chemicals and Z Corporation
Announce R&D Partnership

East Lansing, Mich., April 20 - Ciba Specialty Chemicals Corporation,
Performance Polymers, and Z Corporation, Somerville, Massachusetts, today
announced a research and development partnership to generate new materials
for the rapid generation of three-dimensional (3D) models and prototypes.
The new products will be formulated for use with Z Corporation's Z402*
system that produces solid parts in an office environment in a fraction of
the time required by other 3D printers.
        Ciba and Z Corporation initiated a preliminary product development
effort in October 1998, after Ciba purchased a Z402 system. According to
George Sollner, Vice President and Worldwide Head, Tooling, of Ciba, "Based
on the results of this research and surveys we've conducted of current
prototyping methods, we believe the technology utilized by Z Corporation has
tremendous growth potential in a broad range of manufacturing industries."

Z Corporation CEO, Marina Hatsopoulos, adds, "With Ciba's long-term
experience as a supplier of plastics for rapid prototyping and tooling and
Z Corporation's 3D printing and concept modeling expertise, we believe we
will be able to develop exciting new materials for the fast, support-free
production of durable models and prototypes that require minimal
post-processing." New-generation systems resulting from the research
partnership are also expected to exhibit good accuracy and a smooth surface
finish. Z Corporation will market the new products.

        Ciba Specialty Chemicals is a global leader in fast-setting
polyurethanes that produce thermoplastic-like prototypes in less than 30
minutes as well as castable epoxies for moldmaking. Ciba also recently
introduced a machinable board for producing rapid tooling in just hours.
These materials are used by automotive, appliance, medical equipment and
business machine manufacturers throughout the world to support new product
development. Ciba's traditional tooling products have been used by many of
these same customers for more than 50 years.
        Z Corporation, founded in 1994, markets the Z402 advanced system for
rapidly and economically generating 3D models and prototypes from a starch
and cellulose-based powder. The core technology for the Z402 system was
developed at and patented by MIT, and licensed to Z Corporation. Among Z
Corporation's customers are: Whirlpool, Kodak, Toyota, Daimler Chrysler,
Ford, Motorola and United Technologies, and more than 60 other international
