Shares of Common Stock of The Dow Chemical Company

Pursuant to the Prospectus—Offer to Exchange, dated             , 2015

THE EXCHANGE OFFER AND WITHDRAWAL RIGHTS WILL EXPIRE AT 8:00 A.M., NEW YORK CITY TIME, ON             , 2015, UNLESS THE EXCHANGE OFFER IS EXTENDED OR TERMINATED. SHARES OF COMMON STOCK OF THE DOW CHEMICAL COMPANY TENDERED PURSUANT TO THE EXCHANGE OFFER MAY BE WITHDRAWN AT ANY TIME PRIOR TO THE EXPIRATION OF THE EXCHANGE OFFER.

The undersigned acknowledges receipt of the Prospectus—Offer to Exchange, dated             , 2015 (the “Prospectus”), in connection with the offer by The Dow Chemical Company (“TDCC”) to exchange all issued and outstanding shares of common stock of Blue Cube Spinco Inc., par value $0.001 per share (“Splitco common stock”), which will be converted into shares of Olin Corporation, par value $1 per share, for shares of common stock of TDCC, par value $2.50 per share (“TDCC common stock”), that are validly tendered and not properly withdrawn prior to the expiration of the exchange offer.

Shares of TDCC common stock tendered pursuant to the exchange offer may be withdrawn at any time before 8:00 a.m., New York City time, on             , 2015 (the “Expiration Deadline”), and, unless TDCC has previously accepted them pursuant to the exchange offer, may also be withdrawn at any time after the expiration of 40 business days from the commencement of the exchange offer. Once TDCC accepts shares of TDCC common stock pursuant to the exchange offer, your tender is irrevocable. THIS NOTICE OF WITHDRAWAL IS TO BE USED ONLY TO WITHDRAW TENDERS OF SHARES OF TDCC COMMON STOCK PURSUANT TO THE EXCHANGE OFFER. To withdraw a tender, you must deliver this Notice of Withdrawal to the exchange agent (as defined below) at one of its addresses set forth at the end of this Notice of Withdrawal. If you hold your shares through a broker, dealer, commercial bank, trust company or similar institution, you should consult that institution on the procedures you must comply with and the time by which such procedures must be completed in order for that institution to provide a written notice of withdrawal or facsimile notice of withdrawal to the exchange agent on your behalf before the Expiration Deadline. If you hold your shares through such an institution, that institution must deliver the notice of withdrawal with respect to any shares you wish to withdraw. In such a case, as a beneficial owner and not a registered shareholder, you will not be able to provide a notice of withdrawal for those shares directly to the exchange agent. For more information, see the section of the Prospectus entitled “This Exchange Offer—Terms of this Exchange Offer—Withdrawal Rights.”

If any of the shares of TDCC common stock were tendered through The Depository Trust Company, please do not use this form; use The Depository Trust Company form of withdrawal instead.
