Dear                     :   
     -------------------- 

     [This letter agreement supersedes and replaces in its entirety our letter
agreement of [date] with you relating to severance in the event of a Change in
Control of Olin Corporation.]*

     1.  This agreement shall be binding immediately upon its execution and
delivery, but it shall not be operative unless and until there has been a Change
in Control of Olin Corporation ("Olin"), as defined below.  In the event that
this agreement shall not have become operative by September 30, 2002, it shall
not thereafter become operative or be of any force or effect, notwithstanding
the occurrence of a Change in Control, unless the Board of Directors of Olin
shall have taken action expressly to reapprove this agreement.

     2.  For purposes of this agreement, the following definitions apply:

     (a)  "Change in Control" means:

           (i) Olin ceases to be, directly or indirectly, owned by at least
               1,000 stockholders;


          (ii) a person, partnership, joint venture, corporation or other
               entity, or two or more of any of the foregoing acting as a
               "person" within the meaning of Section 13(d)(3) of the Securities
               Exchange Act of 1934, as amended (the "Act"), other than Olin, a
               majority-owned subsidiary of Olin or an employee benefit plan (or
               the plan's related trust) of Olin or such subsidiary, become(s)
               the "beneficial owner" (as defined in Rule 13d-3 under the Act)
               of 20% or more of the outstanding voting stock of Olin;

 
                                       2



         (iii) during any period of two consecutive years, individuals who at
               the beginning of such period constitute Olin's Board of Directors
               (together with any new Director whose election by Olin's Board of
               Directors or whose nomination for election by Olin's
               stockholders, was approved by a vote of at least two-thirds of
               the Directors then still in office who either were Directors at
               the beginning of such period or whose election or nomination for
               election was previously so approved, cease for any reason to
               constitute a majority of the Directors then in office; or

          (iv) all or substantially all of the business of Olin is disposed of
               pursuant to a merger, consolidation or other transaction in which
               Olin is not the surviving corporation or Olin combines with
               another company and is the surviving corporation (unless the
               shareholders of Olin immediately following such merger,
               consolidation, combination, or other transaction beneficially
               own, directly or indirectly, more than 50% of the aggregate
               voting stock or other ownership interests of (x) the entity or
               entities, if any, that succeed to the business of the Company or
               (y) the combined company).
  
     (b) "Cause" means your willful and continued failure to substantially
          perform your duties; your willful engaging in gross misconduct
          significantly and demonstrably financially injurious to Olin; or your
          willful misconduct in the course of your employment which is a felony
          or fraud. No act or failure to act on your part will be considered
          "willful" unless done or omitted not in good faith and without
          reasonable belief that the action or omission was in the interests of
          Olin or not opposed to the interests of Olin.

     (c) "Olin" includes except for purposes of paragraph 2(a)(iv) above, a
         successor of Olin Corporation (whether direct or indirect) by purchase,
         merger, consolidation or otherwise.
 
     (d)  "Termination" means if:

          (i) Within 18 months following a Change in Control, you are discharged
              by Olin (or any of its subsidiaries) other than for Cause;

         (ii) You terminate your employment within 24 months following a Change
              in Control in the event that:

 
                                       3

              (1)  Olin requires you to relocate your then office to an area
                   which is not within reasonable commuting distance, on a daily
                   basis, from your then residence, except the requirement to
                   relocate your office to Olin's current corporate headquarters
                   located in Norwalk, Connecticut, is not a basis for
                   Termination if (a) in the transfer to Norwalk, Olin
                   reimburses you fully for all your relocation costs consistent
                   with its past practice in effect prior to a Change in Control
                   and (b) you are not age 55 or older with at least ten years
                   of creditable service under an Olin retirement plan at the
                   time of the required relocation;

               (2) Olin reduces your base salary or fails to increase your base
                   salary on a basis consistent (as to frequency and amount)
                   with Olin's exempt salary system as in effect immediately
                   prior to the Change in Control;

               (3) Olin fails to continue your participation in its benefit
                   plans (including incentive compensation and stock options) on
                   substantially the same basis, both in terms of the amount of
                   the benefits provided (other than due to Olin's or a relevant
                   operation's financial or stock price performance provided
                   such performance is a relevant criterion under such plan) and
                   the level of your participation relative to other
                   participants as exists on the date hereof; provided that,
                   with respect to annual and long term incentive compensation
                   plans, the basis with which your amount of benefits and level
                   of participation shall be compared shall be the average
                   benefit awarded to you under the relevant plan during the
                   three years immediately preceding the date of Termination;

               (4) Your duties, position or reporting responsibilities are
                   diminished.

3.   (a) In the event your Termination, Olin will pay you an amount ("Special
         Severance") equal to the sum of:
 

         (i) 12 months' salary at the higher of your base rate of salary in
             effect at Olin (or any subsidiary thereof) immediately prior to the
             Change in Control or on the date of Termination; plus

 
                                       4

        (ii) an amount equal to the greater of (a) the average of your bonus
             awards actually paid (including zero if nothing was paid or
             deferred but including any portion thereof that you elected to
             defer) under the annual cash incentive compensation plans for the
             three calendar years immediately preceding the year in which
             Termination occurs (or the average thereof of such shorter period
             in which you participated in such plans if you participated for
             less than three years), or (b) your standard annual cash incentive
             award for the year in which Termination occurs.

     (b) During the 12-month period following your Termination, you and your
         dependents shall continue to be entitled to coverage under the medical
         and dental insurance plans of Olin, and you shall continue to be
         entitled to coverage under the life insurance plans (other than
         travel/accident) of Olin, in which you participated prior to
         Termination on a basis no less favorable than in effect immediately
         prior to the Change in Control.

     (c) Payment of Special Severance will be made to you (i) over a twelve
         month period in equal monthly installments commencing with the first
         day of the month following the month in which your Termination occurs
         or (ii) at your election, within 30 days of the date of your
         Termination in a lump sum equal to the sum of the monthly payments
         referred to in clause (i) ("Annual Sum") less an amount equal to the
         Annual Sum multiplied by the six-month U.S. Treasury bill rate in
         effect on the date of Termination; provided, however, the amount of the
         Special Severance paid hereunder shall be applied to reduce whatever
         cash severance payments, if any, to which you are entitled under the
         applicable severance policy of Olin or under any special severance
         arrangements which may have been entered into by you with Olin with
         respect to termination of your Olin employment.

     (d) Nothing in this Agreement shall be deemed to limit any provision of the
         Performance Unit Plan, EVA Incentive Plan, Olin 1991 Long Term
         Incentive Plan, any stock option plan or other employee benefit plan of
         Olin which may apply in the event of a Change in Control.

     (e) You shall accrue no vacation following the date of Termination but
         shall be entitled to payment for accrued and unused vacation for the
         then current calendar year within 30 days of Termination.

     (f) You shall not be entitled to an ICP award for the calendar year of
         Termination if Termination occurs during the first calendar quarter.
         If 

 
                                       5

         Termination occurs during or after the second calendar quarter, you
         shall be entitled to prorated ICP award for the calendar year of
         Termination which shall be determined by multiplying your then current
         ICP standard by a fraction the numerator of which is the number of
         weeks elapsed in the calendar year prior to the Termination and the
         denominator of which is 52. You shall accrue no ICP award during the 12
         months following the date of Termination. For purposes of this
         paragraph, "ICP" shall mean the annual cash incentive plan or program
         in effect at the time of Termination.

     4.  The amount of payments provided for in this agreement shall not be
reduced by the amount of compensation, if any, which you may receive from a
third party following your Termination.

     5.  In the event that after a Change in Control your operating unit is to
be sold and you are to be transferred to the purchaser of such operating unit,
and your prospective new employer will not agree to assume this agreement in its
entirety, then you shall be entitled to terminate your employment with Olin
prior to the sale and receive from Olin the payments contemplated by paragraph 3
above, unless Olin shall have agreed to pay you the difference between the
amount of such payments your prospective new employer is prepared to assume and
the amount payable hereunder.

     6.  Anything in this agreement to the contrary notwithstanding:

         (a) In the event that you cease to be employed by Olin for any reason,
             whether at your election or that of Olin, prior to a Change in
             Control, this agreement shall not thereafter become operative or be
             of any force or effect notwithstanding the subsequent occurrence of
             a Change in Control.

     7.  No Employment Rights.  This Agreement shall not be deemed to confer
         --------------------
upon you a right to continued employment with Olin.

     8.  Disputes/Arbitration.
         --------------------

     (a) Any dispute or controversy arising under or in connection with this
         agreement shall be settled exclusively by arbitration at Olin's
         corporate headquarters in accordance with the rules of the American
         Arbitration Association then in effect. Judgment may be entered on the
         arbitrator's award in any court having jurisdiction; provided, however,
         that you shall be entitled to seek specific performance of your right
         to be paid during the pendency of any dispute or controversy arising
         under or in connection with this agreement.

     (b) Olin shall pay as they become due all reasonable legal fees and
         expenses which you may incur to enforce this agreement unless you had
         no reasonable basis for the claim.

 
                                       6

         Should Olin dispute your entitlement to such fees and expenses, the
         burden of proof shall be on Olin to establish that you had no
         reasonable basis for the claim.

                                     Very truly yours,

                                     OLIN CORPORATION
