                                THE GEON COMPANY
                      UNCONDITIONAL AND CONTINUING GUARANTY

WHEREAS, the undersigned, THE GEON COMPANY, a Delaware corporation
("Guarantor"), seeks to induce (i) OLIN SUNBELT, INC., a Delaware corporation
("OSI"), a wholly-owned subsidiary of OLIN CORPORATION, a Virginia corporation
("OC", and OSI and OC being singly and together referred to herein as "Olin") to
execute a partnership agreement (the "Partnership Agreement") with 1997
Chloralkali Venture Inc., an Alabama corporation ("Subsidiary"), a wholly-owned
subsidiary of Guarantor, to form a general partnership to be known as Sunbelt
Chlor Alkali Partnership (the "Partnership"), and (ii) OC to enter into a real
estate lease, an engineering, procurement and construction agreement, and an
operating agreement with the Partnership ("Contracts"); and

WHEREAS, the execution and delivery by Guarantor of this Unconditional and
Continuing Guaranty ("Guaranty") is a condition precedent to Olin's entering
into the Partnership and executing the Contracts;

WHEREAS, Guarantor will derive substantial benefits from such arrangements;

NOW, THEREFORE, in consideration of the premises and of other good valuable
consideration, the receipt of which is hereby acknowledged, Guarantor hereby
represents and agrees as follows:

       1.  GUARANTY. Guarantor hereby absolutely, irrevocably and
           unconditionally guarantees to Olin the full and prompt performance by
           Subsidiary of all of Subsidiary's covenants and obligations under the
           Partnership Agreement, as amended and modified from time to time,
           including, without limitation, the punctual and full performance or
           payment when due, whether at the stated date or dates for such
           payment, by acceleration or otherwise, of all indebtedness,
           liabilities and obligations of Subsidiary under the Partnership
           Agreement, whether absolute or contingent, now existing or hereafter
           arising, and including, without limitation, all contributions,
           interest, premiums, fees, cost and expense reimbursements and all
           other obligations of Subsidiary pursuant to the Partnership
           Agreement, together with all liabilities, rights of contribution and
           indemnities in favor of the Partnership and Olin, imposed in law or
           equity (all of the foregoing are hereinafter sometimes referred to as
           the "Obligations"); provided however, that this Guaranty of the
           Obligations shall be solely for the benefit of the Partnership and
           Olin, and shall not be deemed to create any right in or be in whole
           or in part for the independent benefit of any person other than the
           Partnership and Olin, together with their successors and Permitted
           Assignees. For purposes of this Guaranty, a "Permitted Assignee"
           shall mean an assignee permitted under the Partnership Agreement or
           the Contracts.

       2.  PERFORMANCE BY GUARANTOR. In the event of the occurrence of any
           breach or default in the Obligations, Guarantor hereby agrees to
           perform and/or make payment of each and every Obligation within five
           (5) business days after receipt of notice from Olin of such breach or
           default, provided that for those Obligations reasonably incapable of
           cure within five (5) days, Guarantor shall have commenced a cure
           within five (5) days and thereafter diligently pursue such cure.

       3.  OBLIGATIONS OF GUARANTOR UNCONDITIONAL. Guarantor hereby agrees that:
           (a) Its liability hereunder is unconditional, irrespective of: (i)
               any claim by Subsidiary of lack of authorization or insufficient
               consideration with respect to the Obligations; (ii) the absence
               of any action or effort by Olin or the Partnership to either
               resort to, enforce or exhaust its remedies with respect to the
               Obligations; (iii) the waiver or consent by Olin or the
               Partnership with respect to any provision in the documentation of
               the Obligations (provided that Guarantor shall be entitled to the
               benefit of any such waiver or consent agreed to by Olin directly
               or by the vote of the Management Committee on behalf of the
               Partnership); or (iv) the recovery of any judgment against
               Subsidiary or any action to enforce such judgment or any other
               circumstance which might, absent the unconditional nature of this
               Guaranty, constitute a legal or equitable discharge or defense of
               Guarantor.




   2



           (b) The liability of Guarantor hereunder will not be discharged
               except by complete and final performance and/or payment of the
               Obligations.
           (c) The liability of Guarantor under this Guaranty shall be
               reinstated with respect to any amount paid to the Partnership by
               Subsidiary which is thereafter required to be returned to
               Subsidiary or any trustee, receiver or other representative of or
               for Subsidiary, upon or by reason of the bankruptcy, insolvency,
               reorganization, or dissolution of Subsidiary, or for any other
               reason, other than a valid defense on the merits to the same, all
               as though such amount had never been paid by Subsidiary.
           (d) This is a guarantee of payment and not merely of collection.
           (e) Notwithstanding any provision herein to the contrary, this
               Guaranty shall not limit, amend, modify, impair or otherwise
               affect any right, claim or action of Guarantor or Subsidiary
               arising under the Partnership Agreement or the Contracts.

       4.  WAIVERS. Guarantor hereby expressly waives (a) notice of the
           acceptance of this Guaranty; (b) notice of any change in the rate at
           which any of the Obligations are accruing interest or fees; (c)
           diligence, presentment and demand for performance or payment of any
           of the Obligations; (d) protest, notice of protest, notice of
           dishonor and notice of nonperformance, nonpayment or default to
           Guarantor or to any other person with respect to the Obligations; (e)
           filings of claims or proof of claims with a court in the event of any
           bankruptcy or insolvency proceedings to which Subsidiary is subject;
           (f) any right to require a proceeding first against Subsidiary or any
           other person; (g) any defenses available to a surety under law; and
           (h) all other legally waivable notices to which Guarantor might
           otherwise be entitled.

       5.  CONTINUING GUARANTY. This Guaranty is a continuing Guaranty and shall
           remain in full force and effect and be binding upon Guarantor and its
           successors and assigns, irrespective of any sale of or transfer by
           Guarantor of any or all of the shares of capital stock of Subsidiary,
           until satisfaction in full of all the Obligations.

       6.  MISCELLANEOUS.
           (a) NOTICES. All notices, requests, demands or other communications
               (including telecommunications) to or from Guarantor or Olin shall
               be in writing and shall be deemed to have been duly given or made
               when delivered (i) to Olin, at its office at Cleveland, TN, and
               (ii) to Guarantor, at its address set next to its signature
               below, or as to either party, at such other address as such party
               may hereafter specify to the party in writing. Written notices
               shall be deemed effectively delivered if delivered by hand or by
               registered or certified mail, postage prepaid. The date of
               delivery shall be deemed to be the date the notice is given.
           (b) EXPENSES. Guarantor agrees that, with or without notice to or
               demand upon Subsidiary or Guarantor, Guarantor will pay or
               reimburse Olin (to the extent reimbursement has not already been
               made by Subsidiary) for all expenses, including reasonable fees
               and expenses of its legal counsel, incurred by Olin in connection
               with the collection and the enforcement of any provisions of this
               Guaranty.
           (c) ASSIGNMENTS. Olin may assign its rights and powers under this
               Guaranty to any successor or Permitted Assignee of the Olin
               interest in the Partnership and/or the Contracts, with respect to
               all or any of the Obligations, and, in the event of such
               succession or assignment, the successor or Permitted Assignee of
               such rights and powers, to the extent of such succession or
               assignment, shall have the same rights and remedies as if
               originally named herein in the place of its assignor or
               predecessor in interest.
           (d) WAIVER OF RIGHTS. No delay on the part of Olin in exercising any
               rights hereunder or failure to exercise the same shall operate as
               a waiver of such rights; no notice to or demand on Guarantor
               shall be deemed to be a waiver of the obligation of Guarantor or
               of the right of Olin to take other or further action without
               notice or demand as provided herein. In any event no modification
               or waiver of the provisions hereof shall be effective unless in
               writing nor shall any waiver be applicable except with respect to
               the specific person to whom and in the specific instance or
               matter for which given.

           (e) CUMULATIVE REMEDIES. The obligations of Guarantor hereunder are
               in addition to and not in substitution for any other obligations
               now or hereafter held by Olin and shall not operate as a merger
               of any contract or debt or suspend the fulfillment of, or affect
               the rights, remedies or powers of Olin in respect of, any
               obligation for the fulfillment thereof. The rights and remedies
               provided herein and in any other instrument are cumulative and
               not exclusive of any other rights or remedies provided by law.
           (f) GOVERNING LAW.  This Guaranty shall be governed by, determined 
               and construed in accordance with the laws of the State of 
               Delaware.
           (g) SEVERABILITY. If any part of this Guaranty is contrary to,
               prohibited by or deemed invalid under the applicable law or
               regulations of any jurisdiction, such provision shall, as to such
               jurisdiction, be inapplicable and deemed omitted to the extent so
               contrary, prohibited or invalid, but the remainder hereof shall
               not be invalidated thereby and shall be given full force and
               effect so far as possible, and any such prohibition or invalidity
               in any jurisdiction shall not invalidate or render unenforceable
               such provision in any other jurisdiction.

       IN WITNESS WHEREOF, Guarantor has executed and delivered this Guaranty as
of the 23rd day of August, 1996.
