Cytec Industries Inc. Announces Expiration and Final Results of its Tender Offer for its 4.60% Notes Due July 1, 2013

WOODLAND PARK, N.J.--Cytec Industries Inc. today announced the expiration and final results of its offer to purchase up to $250,000,000 in aggregate principal amount, less any amount accepted in the Any and All Tender Offer of its 5.50% Notes due October 1, 2010 (the “Any and All Tender Offer”), of its 4.60% Notes due July 1, 2013 (the “Maximum Tender Offer”). The Maximum Tender Offer was made pursuant to an Offer to Purchase dated June 30, 2009 (the “Offer to Purchase”), which sets forth a complete description of the terms of the offer and a related offer.

As of 12:00 a.m., New York City time, on July 29, 2009, the aggregate principal amount of 2013 Notes tendered was $70,123,000. As previously announced, Cytec accepted $234,590,000 principal amount of 2010 Notes in the Any and All Tender Offer. Because the aggregate principal amount of 2013 Notes tendered exceeded the Maximum Tender Amount, notes will be purchased on a pro rata basis. As a result, Cytec accepted $15,410,000 in principal amount of 2013 Notes for payment, with settlement expected today. The proration factor, as determined pursuant to the Offer to Purchase, is approximately 22%.

Holders, whose 2013 Notes have been accepted for payment and who tendered before the “Early Tender Date” of 5:00 p.m., New York City time, on July 14, 2009, will receive $950 per $1,000 principal amount of notes accepted for payment, which includes the Early Tender Premium of $20 per $1,000 principal amount. Holders, whose 2013 Notes have been accepted for payment and who tendered after the Early Tender Date, will receive $930 per $1,000 principal amount of notes accepted for payment.
