Agreement Signed for Establishment of Joint Venture to Produce Polycrystalline
Silicon for Solar Applications


Advanced Silicon Materials LLC (ASiMI), a subsidiary of Komatsu Ltd. and a
manufacturer of polycrystalline silicon, and Silicon Technologies AS, a
subsidiary of Renewable Energy Corporation AS (REC) of Norway, have signed a
definitive agreement to establish a joint-venture company dedicated to the
manufacture and sale of polycrystalline silicon for solar applications. Under
the name of Solar Grade Silicon LLC (SGS), the joint venture will start
operations with 50:50 equity participation in September.

SGS expects to launch production of polycrystalline silicon for solar
applications in November of this year, after optimizing the production
technologies for polycrystalline silicon licensed by ASiMI for solar
applications at the Moses Lake Plant which ASiMI will contribute to the joint
venture. SGS also plans to develop fluidized bed technology to produce granular
polycrystalline silicon at a lower cost with a targeted completion date of not
more than three years. ASiMI will have the right to use the technology in the
polycrystalline silicon business for electronic applications.

As REC will finance SGS's technology development program and a majority of its
working capital requirements, it is expected that ASiMI's equity holding ratio
in the joint venture will decline in the future, falling to 25% in three years.

Mr. Michael W. Kerschen, President of ASiMI, commented, "Establishment of this
joint venture should bring substantial merits to both ASiMI and REC. ASiMI will
obtain technology development opportunities and 150 employees of the Moses Lake
Plant will be able to keep their jobs."

Dr. Alf Bjorseth, President of REC, explained, "This joint venture is the
world's first polycrystalline silicon manufacturer exclusively focused on solar
applications, and thus means a momentous step forward for the solar industry. It
will also play an important role for REC to expand its business as a solar
energy company."

Outline of Advanced Silicon Materials LLC
Head Office: Butte, MT, U.S.A.
Line of Business: ASiMI is a leading producer of ultra-high purity
polycrystalline silicon, and the world's largest manufacturer and supplier of
silane gas. Both products are integrated through a unique core technology to
create a base material for silicon wafers and devices produced by the
semiconductor industry.
