Cytec Completes Second Phase of Sale of Two Product Lines

WEST PATERSON, N.J.--Cytec Industries Inc. announced today that it has completed the second of three phases of the sale of its global water treatment chemicals and acrylamide product lines to Kemira Group. The first phase closing included the entire product lines with the exception of Cytec’s Botlek manufacturing site in the Netherlands and certain assets at various subsidiaries in Asia/Pacific and Latin America. This second phase completes the transfer of the Botlek site in the Netherlands to Kemira and adds approximately $21 million proceeds to the $208 million received for the first phase closing in October 2006. In conjunction with the completion of this second phase, Kemira and Cytec have entered into a long term manufacturing agreement where Kemira will continue to manufacture certain products for Cytec at the Botlek site.

An estimated $12 million is expected upon completion of the transfer of the assets at the various subsidiaries for an estimated total of $241 million. The remaining closings are subject to certain conditions and the amount could change due to final working capital transferred.

David Lilley, Chairman, President and Chief Executive Officer, said, “I want to thank the Botlek employees for their hard work through this transition period and we wish them and Kemira well.”
