	KNOW ALL PERSONS BY THESE PRESENTS, that the undersigned hereby constitutes and
appoints each of G. H. Pain, J. E. Fischer, S. C. Mullgardt and T. E. Murphy signing singly, his/her true
and lawful attorney-in-fact and agent for him/her and in his/her name, place and stead, in any and all
capacities to:

	(1)	execute Forms 3, 4 and 5 and any amendments thereto under Section 16(a) of the
Securities Exchange Act of 1934 and the rules relating thereto relating to transactions
involving the securities of Olin Corporation ("Olin");

	(2)	execute Form 144 and any amendments thereto under Rule 144 promulgated under the

execution of any such Form 3, 4, 5 or 144 or amendment and the filing of such form or

	The undersigned hereby grants to each such attorney-in-fact full power and authority to do and
perform all and every act and thing whatsoever requisite, necessary and proper to be done in the exercise
of any of the rights and powers herein granted, as fully to all intents and purposes as the undersigned

attorney and the rights and powers herein granted.

	The undersigned acknowledges that the foregoing attorneys-in-fact, in serving in such capacity at
