As previously announced, holders must validly tender and not subsequently validly withdraw their Notes on or prior to the Expiration Time to be eligible to receive the Total Consideration.

In addition to the Total Consideration, accrued and unpaid interest up to, but not including, the Settlement Date (as defined below) will be payable in cash on all validly tendered and accepted Notes. The Settlement Date is expected to occur tomorrow on November 13, 2014, the next business day following the Expiration Time (the “Settlement Date”).

The closing of the Tender Offer is subject to the satisfaction or waiver of certain conditions as set forth in the Offer to Purchase. Cytec has also exercised its right to optionally redeem any and all Notes not purchased by it in the Tender Offer at a make-whole redemption price, calculated in accordance with the indenture governing the Notes. This press release does not constitute a notice of redemption under the indenture governing the Notes or an obligation to issue such notice.

This press release is for informational purposes only and is neither an offer to purchase nor a solicitation of an offer to sell the Notes. The Tender Offer is being made solely by means of the Offer to Purchase and related Letter of Transmittal, each dated November 5, 2014.

None of Cytec, the Dealer Managers, the depositary or the Information Agent make any recommendation as to whether holders should tender or refrain from tendering their Notes. Holders must make their own decision as to whether to tender Notes and, if so, the principal amount of the Notes to tender.
