Dear Tim:

         We are in receipt of your letter dated September 26, 2007, providing
comments on Cytec's definitive 14A. Your letter states "Please respond to our
comments by October 26, 2007, or tell us by that time when you will provide us
with a response."

         As I advised you yesterday, the members of the Compensation and
Management Development Committee of Cytec's Board of Directors have reviewed
your comment letter and have requested Cytec management to review the Company's
response to your letter with the Committee at its next regularly scheduled
meeting. Because that meeting will be held in conjunction with our December 6,
2007 Board meeting, we will be able to provide you with our response no later
than December 13, 2007.


                                              Very truly yours,

                                              /s/  Roy Smith
