A copy of the Articles of Incorporation, as amended, of the Corporation containing a full statement of the designations, preferences, limitations and relative rights of the shares of Common Stock and Preferred Stock, and the variations in the relative rights, preferences and limitations between the shares of each series of Preferred Stock so far as the same have been fixed and determined, and of the authority of the Board of Directors to fix and determine the relative rights, preferences and limitations of subsequent series, may be obtained, without charge, from the Transfer Agent or the office of the Secretary of the Corporation, upon written request by a Shareholder.

as Attorney to transfer the said Stock on the books of the Corporation with full power of substitution.

Dated						X
								(Sign here exactly as name(s) is shown on the face of this certificate without any change or alteration whatever.)

IMPORTANT NOTICE: When you sign your name to this Assignment Form without filling in the name of your “Assignee” or “Attorney”, this stock certificate becomes fully negotiable, similar to a check endorsed in blank. Therefore, to safeguard a signed certificate, it is recommended that you either (i) fill in the name of the new owner in the “Assignee” blank, or (ii) IF YOU ARE SENDING THE SIGNED CERTIFICATE TO YOUR BANK OR BROKER, fill in the name of the bank or broker in the “Attorney” blank. Alternatively, instead of using this Assignment Form, you may sign a separate “stock power” form and then mail the UNSIGNED stock certificate and the signed “stock power” in separate envelopes. For added protection, use certified or registered mail for a stock certificate.

Keep this certificate in a safe place. If it is lost, stolen or destroyed, the Company will require a bond of indemnity as a condition to the issuance of a replacement certificate.

This certificate also evidences and entitles the holder hereof to certain Rights as set forth in a Rights Agreement dated as of February 27, 1996, as amended from time to time (the “Rights Agreement”), between Olin Corporation (the “Company”) and Mellon Investor Services LLC, as Rights Agent (the “Rights Agent”), the terms of which are hereby incorporated herein by reference and a copy of which is on file at the principal executive offices of the Company. Under certain circumstances, as set forth in the Rights Agreement, such Rights will be evidenced by separate certificates and will no longer be evidenced by this certificate. The Rights Agent will mail to the holder of this certificate a copy of the Rights Agreement without charge after receipt of a written request therefor. Rights beneficially owned by Acquiring Persons or their Affiliates or Associates (as such terms are defined in the Rights Agreement) and by any subsequent holder of such Rights are null and void and nontransferable.
