The formation of joint venture between Kemira Oyj and  Rockwood
Holdings, Inc. has been completed. Creation of the new company is
part of the implementation of Kemira's new strategy. The deal will
create one of the world's leading producers of specialty titanium
dioxide pigments.

The joint venture combines Kemira's titanium dioxide business and
Rockwood's titanium dioxide pigments and functional additives
business. The joint venture, which had pro forma revenues of
approximately 560 million Euros for 2007, is headquartered in
Duisburg, Germany. Wolf-Dieter Griebler, who has been president of
Rockwood's titanium dioxide business, will head the new joint
venture. It is 61 percent owned by Rockwood and 39 percent owned by
Kemira.

The new company, which operates as Sachtleben, is the leading
producer of specialty titanium dioxide pigments for the synthetic
fiber industry, specialty titanium dioxide pigments for packaging
inks and specialty titanium dioxide grades for the cosmetics,
pharmaceutical and food industries. Sachtleben is also the world's
largest producer of synthetic barium sulfate specialties and holds a
unique position in the field of zinc sulfide pigments. Among the
joint venture's competitive advantages are that both companies'
titanium dioxide production is based on a same production process,
and both have strong capabilities in the development of nanoparticles
for specialty applications.
