          OLIN CORPORATION, a corporation duly organized and existing

Record Date referred to below and before the related Interest Payment
Date, the first payment of interest will be made on the Interest
Payment Date following the next succeeding Regular Record Date. The
interest so payable, and punctually paid or duly provided for, on any
Interest Payment Date (other than at Maturity) will, as provided in
such Indenture, be paid to the Person in whose name this Security (or
one or more Predecessor Securities) is registered at the close of
business on the Regular Record Date for such interest, which shall be
June 1 or December 1 (whether or not a Business Day), unless otherwise
indicated in the applicable Pricing Supplement, as the case may be,
next preceding such Interest Payment Date; provided, however, that
interest payable at Maturity shall be payable to the Person to whom
principal shall be payable. If any Interest Payment Date would fall on
a day that is not a Business Day, such Interest Payment Date will be
the following day that is a Business Day, and no interest on such

case may be.

          Payment of the principal, premium, if any, and interest on
this Security will be made at the principal corporate trust office of
the Trustee in the Borough of Manhattan, The City of New York, or such
other office or agency of the Company as may be designated by it for
such purpose in the Borough of Manhattan, The City of New York (the
"Paying Agent"), in such coin or currency of the United States of
America as at the time of payment is legal tender for payment of
public and private debts; provided, however, that at the option of the
Company, payment of interest (except at Maturity) may be made by
United States dollar check mailed to the address of the Person
entitled thereto as such address shall appear in the Security
Register. Payment of the principal, premium, if any, and interest on
this Security due at Maturity will be made in immediately available
funds upon surrender of this Security to the Paying Agent; provided
that this Security is presented to the paying agent in time for the
paying agent to make such payment in accordance with its normal
procedures. "Maturity" shall mean the date on which the principal of





                                                                       3

this Security or an installment of principal becomes due, whether on
the Maturity Date specified above, upon redemption or otherwise.

          REFERENCE IS HEREBY MADE TO THE FURTHER PROVISIONS OF THIS
SECURITY SET FORTH IN FULL ON THE REVERSE HEREOF, WHICH FURTHER
PROVISIONS SHALL FOR ALL PURPOSES HAVE THE SAME EFFECT AS IF SET FORTH
IN FULL AT THIS PLACE.

          Unless the certificate of authentication hereon has been
executed by the Trustee referred to on the reverse hereof, directly or
through an authenticating agent, by manual signature of an authorized
officer, this Security shall not be entitled to any benefit under the
Indenture or be valid or obligatory for any purpose.

                      MEDIUM-TERM NOTE, SERIES A

                             (Fixed Rate)

          This Security is one of a duly authorized issue of
securities of the Company (herein called the "Securities"), issued and
to be issued in one or more series under an Indenture, dated as of
June 15, 1992, as supplemented as of March 18, 1994 (herein called the
"Indenture"), between the Company and Chemical Bank, as Trustee
(herein called the "Trustee", which term includes any successor
trustee under the Indenture), to which Indenture and all indentures
supplemental thereto reference is hereby made for a statement of the
respective rights, limitations of rights, duties and immunities
thereunder of the Company, the Trustee and the Holders of the
Securities and of the terms upon which the securities are, and are to
be, authenticated and delivered. This Security is one of the series
designated on the face hereof.

          This Security may not be redeemed prior to the Redemption
Date set forth on the face hereof. If no Redemp- tion Date is so set
forth, this Security is not redeemable prior to the Maturity Date. On
or after the Redemption Date set forth on the face hereof, this
Security is redeemable in whole or in part in increments of U.S.
$1,000 at the option of the Company at a redemption price equal to
100% of the principal amount to be redeemed together with interest
thereon to the date of redemption.

          Notice of redemption will be given by mail to Holders of
Securities, at least 30 and not more than 60 days prior to the date
fixed for redemption, all as provided in the Indenture.

          In the event of redemption of this Security in part only, a
new Security or Securities of this series and of like tenor for the
unredeemed portion hereof will be issued in the name of the Holder
hereof upon the surrender hereof.

          The Securities of this series will not have a sinking fund
unless otherwise specified in the applicable pricing supplement.





                                                                     5

          Subject to a number of important qualifications and
exceptions set forth in the Indenture, the Indenture provides that
neither the Company nor any Restricted Subsidiary (as defined in the
Indenture) will (i) issue, assume or guarantee any notes, bonds,
debentures or other similar evidences of indebtedness for money
borrowed secured by a mortgage, lien, pledge or other encumbrance upon
any real or personal property located in the continental United States
of America without effectively providing that the Securities will be
secured equally and ratably with (or, at the option of the Company,
prior to) such indebtedness so long as such indebtedness shall be so
secured or (ii) enter into any Sale and Lease-Back Transactions (as
defined in the Indenture).

          The Indenture also provides that the Company at its option
(a) will be Discharged (as such term is defined in the Indenture) from
any and all obligations in respect of the Securities (except for
certain obligations to register the transfer or exchange of
Securities, replace stolen, lost or mutilated Securities, maintain
paying agencies and hold moneys for payment in trust) or (b) need not
comply with certain restrictive covenants of the Indenture, if there
is deposited with the Trustee money or U.S. Government Obligations (as
defined in the Indenture), which through the payment of interest
thereon and principal thereof in accor- dance with their terms will
provide money or a combination of money and U.S. Government
Obligations in an amount sufficient to pay all the principal, premium,
if any, and interest on, the Securities on the dates such payments are
due in accordance with the terms of the Securities.

          Interest payments for this Security will include interest
accrued to but excluding the Interest Payment Date. Interest payments
for this Security shall be computed and paid on the basis of a 360-day
year of twelve 30-day months.

          The interest rate on this Security will in no event be
higher than the maximum rate permitted by New York law as the same may
be modified by United States law of general applicability.

          If an Event of Default with respect to Securities of this
series shall occur and be continuing, the principal of the Securities
of this series may be declared due and payable in the manner and with
the effect provided in the Indenture.





                                                                     6

          The Indenture permits, with certain exceptions as therein
provided, the amendment thereof and the modification of the rights and
obligations of the Company and the rights of the Holders of the
Securities of each series to be affected under the Indenture at any
time by the Company and the Trustee with the consent of the Holders of
66 2/3% in principal amount of the Securities at the time Outstanding
of each series to be affected. The Indenture also contains provisions
permitting the Holders of specified percentages in principal amount of
the Securities of each series at the time Outstanding, on behalf of
the Holders of all Securities of such series, to waive compliance by
the Company with certain provisions of the Indenture and certain past
defaults under the Indenture and their consequences. Any such consent
or waiver by the Holder of this Security shall be conclusive and
binding upon such Holder and upon all future Holders of this Security
and of any Security issued upon the registration of transfer hereof or
in exchange herefor or in lieu hereof, whether or not notation of such
consent or waiver is made upon this Security.

          As set forth in, and subject to, the provisions of the
Indenture, no Holder of any Security of this series will have any
right to institute any proceeding with respect to the Indenture or for
any remedy thereunder, unless such Holder shall have previously given
to the Trustee written notice of a continuing Event of Default with
respect to this series, the Holders of not less than 25% in principal
amount of the Outstanding Securities of this series shall have made
written request, and offered reasonable indemnity, to the Trustee to
institute such proceeding as trustee, the Trustee shall not have
received from the Holders of a majority in principal amount of the
Outstanding Securities of this series a direction inconsistent with
such request and the Trustee shall have failed to institute such
proceeding within 60 days; provided, however, that such limitations do
not apply to a suit instituted by the Holder hereof for the
enforcement of payment of the principal, premium, if any, or interest
on this Security on or after the respective due dates expressed
herein.

          No reference herein to the Indenture and no provision of
this Security or of the Indenture shall alter or impair the obligation
of the Company, which is absolute and unconditional, to pay the
principal, premium, if any, and interest on this Security at the
times, places and rate, and in the coin or currency, herein
prescribed.





                                                                     7

          As provided in the Indenture and subject to certain
limitations therein set forth, the transfer of this Security is
registrable in the Security Register, upon surrender of this Security
for registration of transfer at the corporate trust office of the
Trustee or such other office or agency as may be designated by the
Company in the Borough of Manhattan, The City of New York, duly
endorsed by, or accompanied by a written instrument of transfer in
form satisfactory to the Company and the Security Registrar duly
executed by, the Holder hereof or his attorney duly authorized in
writing, and thereupon one or more new Securi- ties of this series and
of like tenor, of authorized denomi- nations and with like terms and
conditions and for the same aggregate principal amount, will be issued
to the designated transferee or transferees.

          The Securities of this series are issuable only in
registered form, without coupons, in denominations of $1,000 and any
integral multiple of $1,000 in excess thereof. As provided in the
Indenture and subject to certain limitations therein set forth,
Securities of this series are exchangeable for a like aggregate
principal amount of Securities of this series and of like tenor of a
different authorized denomination and with like terms and conditions,
as requested by the Holder surrendering the same.

          No service charge shall be made for any such registration of
transfer or exchange, but the Company may require payment of a sum
sufficient to cover any tax or other governmental charge payable in
connection therewith.

                  Prior to due presentment of this Security for
registration of transfer, the Company, the Trustee and any
agent of the Company or the Trustee may treat the Person in
whose name this Security is registered as the owner hereof
for all purposes, whether or not this Security is overdue,
and neither the Company, the Trustee nor any such agent
shall be affected by notice to the contrary.

          The Indenture and the Securities shall be governed by and
construed in accordance with the laws of the State of New York.

          All terms used in this Security which are defined in the
Indenture shall have the meanings assigned to them in the Indenture.





                                                                      8
