Clariant, Zhejiang Baihe To Expand Joint Venture

Clariant International Ltd., Switzerland, and Zhejiang Baihe Chemical Holding Group, China —
partners in the joint venture Hangzhou Baihe Clariant Pigments Co. Ltd. — have announced they will
expand the joint venture for the production of quinacridone specialty organic pigments. The
pigments are increasingly found in high-performance coatings used in printing, architectural,
automotive, plastics and industrial applications.

“The partnership between Baihe Chemical and Clariant has been proven very successful,” said
Chen Li Rong, chairman of Zhejiang Baihe Chemical’s Board of Directors. “So both parties have
agreed to expand our cooperation from high-performance azo organic pigments to quinacridone and
other high-performance organic pigments. At the same time, Clariant will be responsible for
marketing quinacridone and other pigments on a worldwide basis.”

The new facility will be built at Hangzhou Baihe Clariant Pigment’s current location in Hang
Zhou City, Zhejiang Province. Construction and equipment installation will begin in the fourth
quarter of this year. Production is expected to commence by the end of 2009.
