                              STATEMENT OF PURPOSE
                              --------------------

1.1  The purpose of the EVA Incentive Plan (the "Plan") is to provide a system
     of incentive compensation which will promote the maximization of Economic
     Value Added ("EVA") over the long term.  In order to align management
     incentives with shareholder interests, incentive compensation will reward
     the creation of value.  This Plan will tie incentive compensation to EVA
     and, thereby, reward management for creating value and penalize management
     for destroying value.

1.2  EVA is the performance measure of value creation for Olin Corporation (the
     "Company").  Managers create value when they employ capital in an endeavor
     that generates a return that exceeds the cost of the capital employed.
     Managers destroy value when they employ capital in an endeavor that
     generates a return that is less than the cost of capital employed.  By
     imputing the cost of capital upon the operating profits generated by a
     business group, EVA measures the total value created (or destroyed) by
     management.  The Plan will reward increases in EVA and penalize decreases
     over time.


                                   ARTICLE II

     Expected Improvement in EVA, Leverage Factor and Target EVA may be adjusted
     from time to time for a fiscal year to reflect extraordinary or

                                  -----------

6.1  NO CONTINUED EMPLOYMENT.  Nothing contained herein shall provide any
     -----------------------                                             
     employee with any right to continued employment or in any way abridge the
     rights of the Company and its subsidiaries to determine the terms and
     conditions of employment and whether to terminate employment of any
     employee. Neither the establishment of the Plan or the grant of an award or
     bonus hereunder shall be deemed to constitute an express or implied
     contract of employment for any period of time or in any way abridge the

     conditions of employment or to terminate the employment of any employee
     with or without cause at any time.

     or otherwise) to any award, allocation, or distribution or any right,
     title, or vested interest in any amounts in his Bonus Bank and no officer
     or employee of the Company or any subsidiary or any other person shall have
     any authority to make representations or agreements to the contrary.  No
     interest conferred herein to a Participant shall be assignable or subject
     to any lien or pledge or any claim by a Participant's creditors.  The right
     of the Participant to receive a distribution thereunder shall be an
     unsecured claim against the general assets of the Company and the
     Participant shall have no rights in or against any specific assets of the
     Company as the result of participation hereunder.

6.3  NOT PART OF OTHER BENEFITS.  The benefits provided in this Plan shall not
     --------------------------

     of the Company or any of its subsidiaries, whether or not Participants in

     part to provide deferred compensation to a select group of management and
     highly compensated employees.  Nothing herein shall create or be conjured
     to create a trust or separate fund of any kind, or a fiduciary relationship
     between the Company (or any of its subsidiaries) and any Participant.


                                  ARTICLE VII

                                   AUTHORITY

     Participant under the Plan.  Any decision taken by the Committee arising
     out of or in connection with the construction, administration,
     interpretation and effect of the Plan shall be final, conclusive and
     binding upon all Participants and any person claiming under or through
     them.  The Committee may delegate its power and authority with respect to
     the Plan to the Chief Executive Officer from time to time as it determines.

10.1 This Plan may be amended, suspended or terminated in whole or in part at
     any time from time to time at the sole discretion of the Committee;
     provided, however, that no such change in the Plan shall be effective to
     eliminate or diminish the distribution of any award that has been allocated
     to the Bonus Bank of a Participant prior to the date of such amendment,
     suspension or termination.  Notice of any such amendment, suspension of
     termination shall be given promptly to each Participant.
