Item 1.01     Entry Into a Material Definitive Agreement

         On January 4, 2005, Cytec Industries Inc. ("Cytec") and UCB SA ("UCB")
entered into the First Amendment (the "First Amendment") to the Stock and Asset
Purchase Agreement, dated October 1, 2004 between Cytec and UCB (the "Purchase
Agreement"). The First Amendment provides for certain adjustments to the
financial statements of UCB's specialty chemicals business. The First Amendment
also amends certain schedules to the Purchase Agreement and certain cross
references in the Purchase Agreement. The First Amendment is not a Material
Definitive Agreement within the meaning of Regulation S-K.

         On February 7, 2005, Cytec and UCB announced that they had entered into
the Second Amendment to the Purchase Agreement (the "Second Amendment"). The
Second Amendment amends the Purchase Agreement to reduce the purchase price
payable by Cytec to the equivalent of EUR 1.415 billion ($1.840 billion at
1.30$/EUR), including contingent payments of up to a maximum of EUR 50
million. The purchase price was reduced from the previously announced EUR 1.5
billion. The contingent consideration is earned on a pro rata basis pending the
achievement of certain operating results by the acquired business in 2005. The
non-cash portion of the consideration will be paid, as previously agreed in the
Purchase Agreement, in 5,772,857 shares of Cytec common stock valued at
EUR 225 million when the Purchase Agreement was executed. The acquisition
remains subject to U.S. regulatory approval as well as other customary closing
conditions.

         The Second Amendment and the related press release dated February 7,
2005 are incorporated by reference in this Item 1.01.
