Cytec announces changes in tender offer

Cytec reserves the right to increase the Maximum Principal Amount to be Accepted or the maximum aggregate principal amount of $200,000,000 at any time, subject to compliance with applicable law.

The Tender Offers are being made pursuant to an Offer to Purchase dated February 26, 2013 (as amended and supplemented, the "Offer to Purchase") and the related Letter of Transmittal dated February 26, 2013 (as amended and supplemented, the "Letter of Transmittal"), which set forth a complete description of the terms of the Tender Offers.

Holders of the Securities are urged to read the Offer to Purchase and the related Letter of Transmittal carefully before making any decision with respect to the Tender Offers. The Tender Offers are conditioned on the satisfaction of certain conditions set forth in the Offer to Purchase.

Cytec has retained Citigroup Global Markets Inc., RBS Securities Inc. and Wells Fargo Securities, LLC to serve as dealer managers for the Tender Offers. Global Bondholder Services Corporation has been retained to serve as the depositary and information agent for the Tender Offers.

Copies of the Offer to Purchase and the Letter of Transmittal related to the Tender Offers may also be obtained at no charge from Global Bondholder Services Corporation.

Neither Cytec, its board of directors, the information agent and depositary nor the dealer managers make any recommendation as to whether holders of the Securities should tender or refrain from tendering the Securities. Holders of the notes must decide how many notes to tender, if any.

This announcement does not constitute an offer to purchase or a solicitation of an offer to sell securities. The Tender Offers are being made solely by means of the Offer to Purchase and the related Letter of Transmittal. In any jurisdiction where the laws require a tender offer to be made by a licensed broker or dealer, the Tender Offers will be deemed to be made on behalf of Cytec by the dealer managers or one or more registered brokers or dealers under the laws of such jurisdiction.
