Board Authority. If the Committee does not exist, or for any other reason determined by the Board, the Board may take any action under the Plan that would otherwise be the responsibility of the Committee.

Delegation. Notwithstanding any provision of the Plan to the contrary, except to the extent prohibited by applicable law or the applicable rules of a stock exchange, the Committee may delegate to one or more officers or managers of Olin or any Affiliate, or a committee of such officers or managers, the authority, subject to such terms and limitations as the Committee shall determine, to grant Awards to, or to cancel, modify, waive rights or conditions with respect to, alter, discontinue, suspend, or terminate Awards held by, Employees who are not officers or directors of Olin for purposes of Section 16 of the Exchange Act, provided that no such action shall result in repricing of Options prohibited by Section 3(e).

Prohibition on Option Repricing. Notwithstanding any other provision of the Plan, neither the Board nor the Committee may reprice, replace or regrant any Option granted under the Plan or any other plan of Olin, (i) through cancellation and replacement or regrant with lower priced options or (ii) by lowering the option exercise price of a previously granted award, without the prior approval of Olin’s shareholders.

The aggregate number of Shares available for granting Awards under the Plan shall be 1,700,000.

For purposes of this Section 4, other than Sections 4(c)(ii) and 4(c)(iii):

If any Shares covered by an Award are not delivered to a Participant or beneficiary because the Award is forfeited or canceled, or if the Shares are not delivered because the Award is settled in cash or used to satisfy the applicable tax withholding obligation, such Shares shall not be deemed to have been delivered for purposes of determining the maximum number of Shares available for delivery under the Plan; and

If the exercise price of any Option granted under the Plan is satisfied by tendering Shares (by either actual delivery or by attestation), only the number of Shares issued net of the Shares tendered shall be deemed delivered for purposes of determining the maximum number of Shares available for delivery under the Plan.

Adjustments. In the event of any change in the Shares by reason of stock dividends, stock splits, recapitalization, mergers, consolidations, combinations or exchanges of shares, split-ups, split-offs, spin-offs, liquidations or other similar changes in capitalization, or any distributions to shareholders other than cash dividends, (i) the numbers, class and prices of Shares covered by outstanding Awards under the Plan (provided that no such adjustment shall result in repricing of Options prohibited by

With respect to Awards of Incentive Stock Options, no such adjustment shall be authorized to the extent that such authority would cause the Plan to violate Section 422 of the Code or any successor provision thereto, unless the holder of such Award of Incentive Stock Options agrees to convert such options to Non-qualified Stock Options.

Notwithstanding the foregoing, a Participant to whom Dividend Equivalents or dividend units have been awarded shall not be entitled to receive a special or extraordinary dividend or distribution unless the Committee shall have expressly authorized such receipt.

Additional Restrictions. Subject to adjustment as provided in Section 4(b), the following additional maximums are imposed under the Plan:

Option Term. The term of each Option shall be fixed by the Committee, provided that in no event shall the term of an Option be more than a period of ten years from the date of its grant.

Exercise. The Committee shall determine the time or times at which an Option may be exercised in whole or in part, and the method or methods by which, and the form or forms in which payment of the exercise price with respect thereto may be made.

Incentive Stock Options. The terms of any Incentive Stock Option granted under the Plan shall comply in all respects with the provisions of Section 422 of the Code, or any successor provision thereto, and any regulations promulgated thereunder. Without limiting the preceding sentence, the aggregate Fair Market Value (determined at the time an Option is granted) of Shares with respect to which Incentive Stock Options are exercisable for the first time by a Participant during any calendar year (under the Plan and any other plan of the Participant’s employer corporation and its parent and subsidiary corporations providing for Options) shall not exceed such dollar limitation as shall be applicable to Incentive Stock Options under Section 422 of the Code or a successor provision.

Termination of Employment. In the event the employment of a Participant to whom an Option has been granted under the Plan shall be terminated (other than by reason of the Participant’s death or disability), such Option may,

Agreement to Service. Each Participant receiving an Option shall, by accepting the Option, agree that he or she will, during employment, devote his or her entire time, energy and skill to the service of Olin and the promotion of its interests, subject to vacations, sick leave and other absences in accordance with the regular policies of, or other reasons satisfactory to, Olin and its Affiliates. Such employment shall (subject to the terms of any contract between Olin or any such Affiliate and such Participant) be at the pleasure of Olin or such Affiliate, and shall be at such compensation as Olin or such Affiliate shall determine from time to time. Upon termination of such Participant’s employment either (a) for cause, or (b) voluntarily on the part of the Participant and without the written consent of Olin, any Awards held by him or her under the Plan, to the extent not theretofore exercised or vested, shall forthwith terminate. Retirement pursuant to any retirement plan of Olin or of an Affiliate shall be deemed to be a termination of employment with Olin’s consent.

Death. If a Participant to whom an Option has been granted shall die while an Employee, such Option may be exercised by the Participant’s executors, administrators, personal representatives or distributees or permitted transferees at any time within a period of one year after the Participant’s death (which period may be extended by the Committee), regardless of whether or not such Option had vested at the time of death. If a Participant to whom an Option has been granted shall die after his or her employment has terminated but while the Option remains exercisable, the Option may be exercised by the persons described above at any time within the longer of (a) the period that the Participant could have exercised the Option had he or she not died, or (b) one year after the date of death (which period may be extended by the Committee), but only to the extent the Option was exercisable at the time of the Participant’s death.

Disability. If a Participant to whom an Option has been granted shall become totally and permanently disabled, as that term is defined in Section 22(e)(3) of the Code (or a successor provision), and the Participant’s employment is terminated as a result, such option may be exercised by the Participant or permitted transferee within one year after the date of termination of

Stock Appreciation Rights. The Committee is authorized to grant Stock Appreciation Rights to Participants which may but need not relate to a specific Option granted under the Plan. Subject to the terms of the Plan and any applicable Award Agreement, each Stock Appreciation Right granted under the Plan shall confer on the holder thereof a right to receive, upon exercise thereof, up to the excess of (i) the Fair Market Value of one Share on the date of exercise over (ii) the exercise price of the right as specified by the Committee, which shall not be less than the Fair Market Value of one Share on the date of grant of the Stock Appreciation Right.

Issuance. The Committee is authorized to grant Awards of Restricted Stock, Restricted Stock Units and Performance Shares to Participants.

Dividends and Dividend Equivalents. An Award (including without limitation an Option or Stock Appreciation Right) may provide the Participant with the right to receive dividend payments or dividend equivalent payments with respect to Shares subject to the Award (both before and after the Shares subject to the Award are earned, vested, or acquired), which payments may be either made currently or credited to an account for the Participant, and may be settled in cash or Shares as determined by the Committee; provided, however that, no dividend payments or dividend equivalent payments shall be provided, permitted or credited to the extent that such payments would cause an Option or Stock Appreciation Right to be subject to Code Section 409A. Any such settlements, and any such crediting of dividends or dividend equivalents or reinvestment in Shares, may be subject to such conditions, restrictions and contingencies as the Committee shall establish, including the reinvestment of such credited amounts in Share equivalents.

Restrictions. Any such Award shall be subject to such conditions, restrictions and contingencies as the Committee may impose (including, without limitation, any limitation on the right to vote Restricted Stock or the right to receive any dividend or other right or property), which may lapse separately or in combination at such time or times, as the Committee may deem appropriate, provided that in order for a Participant to vest in Awards of Restricted Stock, the Participant must remain in the employ of Olin or an

Forfeiture. Except as otherwise determined by the Committee, upon termination of employment for any reason during the applicable restriction period, all Shares of Restricted Stock still subject to restriction shall be forfeited and reacquired by Olin.

The exercise price shall be payable in cash or by tendering, by either actual delivery of Shares or by attestation, Shares acceptable to the Committee, which Shares were either acquired at least six months before the exercise date or purchased on the open market, and valued at Fair Market Value as of the day of exercise, or in any combination thereof, as determined by the Committee.

The Committee may permit a Participant to elect to pay the exercise price upon the exercise of an Option by irrevocably authorizing a third party to sell Shares (or a sufficient portion of the Shares) acquired upon exercise of an Option and remit to Olin a sufficient portion of the sale proceeds to pay the entire exercise price and any tax withholding resulting from such exercise.

Limits on Transfer of Awards. No Award (other than Released Securities) or right thereunder shall be assignable or transferable by a Participant, other than:

by will or the laws of descent and distribution (or, in the case of an Award of Restricted Securities, to Olin); or

General.

No Cash Consideration for Awards. Participants shall not be required to make any cash payment for the granting of an Award except for such minimum consideration as may be required by applicable law.

Awards May Be Granted Separately or Together. Awards may be granted either alone or in addition to, in tandem with, or in substitution for any other Award or any award or benefit granted under any other plan or arrangement of Olin or any Affiliate, or as payment for or to assure payment of an award or benefit granted under any such other such plan or arrangement, provided that the purchase or exercise price under an Option or other Award encompassing the right to purchase Shares shall not be reduced by the cancellation of such Award and the substitution of another Award. Awards so granted may be granted either at the same time as or at a different time from the grant of such other Awards or awards or benefits.

General Restrictions. Delivery of Shares or other amounts under the Plan shall be subject to the following:

Notwithstanding any other provision of the Plan, Olin shall have no liability to deliver any Shares under the Plan or make any other distribution of benefits under the Plan unless such delivery or distribution would comply with all applicable laws (including, without limitation, the requirements of the Securities Act of 1933), and the applicable requirements of any securities exchange or similar entity.

To the extent that the Plan provides for issuance of stock certificates to reflect the issuance of Shares the issuance may be effected on a non-certificated basis, to the extent not prohibited by applicable law or the applicable rules of any stock exchange.

Agreement With Olin. An Award under the Plan shall be subject to such terms and conditions, not inconsistent with the Plan, as the Committee shall, in its sole discretion, prescribe. The terms and conditions of any Award to any Participant may be reflected in such form of written document as is determined by the Committee. A copy of such document shall be provided to the Participant, and the Committee may, but need not, require the Participant to sign a copy of such document, (an “Award Agreement” regardless of whether any Participant signature is required).

Beneficiary. A Participant may, in the manner established by the Committee, designate a beneficiary or beneficiaries with respect to any Award to exercise the rights of the Participant, and to receive any property distributable, upon the death of the Participant. Each Award, and each right under any Award, shall be exercisable, during the Participant’s lifetime, only by the Participant

No Lien or Security Interest.

No Rights to Awards. No Employee, Participant or other Person shall have any claim to be granted an Award, and there is no obligation for uniformity of treatment of Employees, Participants or beneficiaries of Awards under the Plan. The terms and conditions of Awards need not be the same with respect to each recipient. The prospective recipient of any Award under the Plan shall not, with respect to such Award, be deemed to have become a Participant, or to have any rights with respect to such Award, until and unless such recipient shall have executed an agreement or other instrument accepting the Award required by the Committee and delivered a fully executed copy thereof to Olin, and otherwise complied with the then applicable terms and conditions.

Withholding. All distributions under the Plan are subject to withholding of all applicable taxes, and, except as otherwise provided by the Committee, the delivery of any Shares or other benefits under the Plan to a Participant are conditioned on satisfaction of the applicable withholding requirements. The Committee, in its discretion, and subject to such requirements as the Committee may impose prior to the occurrence of such withholding, may permit such withholding obligations to be satisfied through cash payment by the Participant, through the surrender of Shares which the Participant already owns, or through the surrender of Shares to which the Participant is otherwise entitled under the Plan.

Other Compensation Arrangements. Nothing contained in the Plan shall prevent Olin or any Affiliate from adopting or continuing in effect other or additional compensation arrangements, and such arrangements may be either generally applicable or applicable only in specific cases.

No Right to Employment. The grant of an Award shall not be construed as giving a Participant the right to be retained in the employ of Olin or any Affiliate. Nothing in the Plan or any Award Agreement shall limit the right of Olin or an Affiliate at any time to dismiss a Participant from employment, free from any liability or any claim under the Plan or the Award Agreement.

Governing Law. The validity, construction and effect of the Plan and any rules and regulations relating to the Plan shall be determined in accordance with the laws of the State of Connecticut, excluding any conflicts or choice

Severability. If any provision of the Plan or any Award is determined to be invalid, illegal or unenforceable, or as to any Person or Award, or would disqualify the Plan or any Award, such provision shall be construed or deemed amended to conform to applicable laws, or, if it cannot be so construed or deemed amended without, in the determination of the Committee, materially altering the intent of the Plan or the Award, such provision shall be stricken as to such Person or Award, and the remainder of the Plan and any such Award shall remain in full force and effect.

No Trust or Fund Created. Neither the Plan nor any Award shall create or be construed to create a trust or separate fund of any kind or a fiduciary relationship between Olin or any Affiliate and a Participant or any other Person. To the extent that any Person acquires a right to receive payments from Olin or any Affiliate pursuant to an Award, such right shall be no greater than the right of any unsecured general creditor of Olin or any Affiliate.

No Fractional Shares. No fractional Shares shall be issued or delivered pursuant to the Plan or any Award, and the Committee shall determine whether cash, other securities or other property shall be paid or transferred in lieu of any fractional Shares, or whether such fractional Shares or any rights thereto shall be canceled, terminated or otherwise eliminated.

Share Certificates. All certificates for Shares or other securities delivered under the Plan pursuant to any Award or the exercise thereof shall be subject to such stop transfer orders and other restrictions as the Committee may deem advisable under the Plan or the rules, regulations and other requirements of the Securities and Exchange Commission, any stock exchange upon which such Shares or other securities are then listed, and any applicable Federal or state securities laws, and the Committee may cause a legend or legends to be put on any such certificates to make appropriate reference to such restrictions.

Conflict with Plan. In the event of any inconsistency or conflict between the terms of the Plan and an Award Agreement, the terms of the Plan shall govern.

Amendments to the Plan. The Board or the Committee may amend, suspend, discontinue or terminate the Plan, including, without limitation, any amendment, suspension, discontinuation or termination that would impair the rights of any Participant, or any other holder or beneficiary of any Award theretofore granted, without the consent of any shareholder, Participant, other holder or beneficiary of

reduce the minimum Option exercise price, except as provided in Section 4(b); or

permit repricing of Options prohibited by Section 3(e); and

Amendments to Awards. The Committee may waive any conditions or rights with respect to, or amend, alter, suspend, discontinue, or terminate, any unexercised Award theretofore granted, prospectively or retroactively, without the consent of any relevant Participant or holder or beneficiary of an Award, provided that no amendment, alteration, suspension, discontinuation or termination of an Award that would impair the rights of such Participant, holder or beneficiary shall be made after a Change in Control; provided further that the Committee may not increase the payment of any Award granted any Participant.

Adjustments of Awards Upon Certain Acquisitions. In the event Olin or any Affiliate shall assume outstanding employee awards or the right or obligation to make future such awards in connection with the acquisition of another business or another Person, the Committee may make such adjustments, not inconsistent with the terms of the Plan, in the terms of Awards as it shall deem appropriate.

Adjustments of Awards Upon the Occurrence of Certain Unusual or Nonrecurring Events. The Committee may make adjustments in the terms and conditions of Awards in recognition of unusual or nonrecurring events (including, without limitation, the events described in Section 4(b) hereof) affecting Olin, any Affiliate, or the financial statements of Olin or any Affiliate, or of changes in applicable laws, regulations, or accounting principles, whenever the Committee determines that such adjustments are appropriate in order to prevent dilution or enlargement of the benefits to be made available under the Plan.

A Participant shall not render services for any Person or engage, directly or indirectly, in any business which, in the judgment of the Committee is or becomes competitive with Olin or any Affiliate, or which is or becomes otherwise prejudicial to or in conflict with the interests of Olin or any Affiliate. Such judgment shall be based on the Participant’s positions and responsibilities while employed by Olin or an Affiliate, the Participant’s post-employment responsibilities and position with the other Person or business, the extent of past, current and potential competition or conflict between Olin or an Affiliate and the other Person or business, the effect on customers, suppliers and competitors of the Participant’s assuming the post-employment position, the guidelines established in the then current edition of Olin’s Standards of Ethical Business Practices, and such other considerations as are deemed relevant given the applicable facts and circumstances. The Participant shall be free, however, to purchase as an investment or otherwise, stock or other securities of such Person or business so long as they are listed upon a recognized securities exchange or traded over the counter, and such investment does not represent a substantial investment to the Participant or a greater than 1% equity interest in the organization or business.

Participant shall not, without prior written authorization from Olin, disclose to anyone outside Olin, or use in other than Olin’s business, any secret or confidential information, knowledge or data, relating to the business of Olin or an Affiliate in violation of his or her agreement with Olin or the Affiliate.

A Participant, pursuant to his or her agreement with Olin or an Affiliate, shall disclose promptly and assign to Olin or the Affiliate all right, title and interest

Notwithstanding any other provision of the Plan, the Committee in its sole discretion may cancel any Award at any time prior to the exercise thereof, if the employment of the Participant shall be terminated, other than by reason of death, unless the conditions in this Section 8 are met.

Failure to comply with the conditions of this Section 8 prior to, or during the six months after, any exercise, payment or delivery pursuant to an Award shall cause the exercise, payment or delivery to be rescinded. Olin shall notify the Participant in writing of any such rescission within two years after such exercise payment or delivery and within 10 days after receiving such notice, the Participant shall pay to Olin the amount of any gain realized or payment received as a result of the exercise, payment or delivery rescinded. Such payment shall be made either in cash or by returning to Olin the number of Shares that the Participant received in connection with the rescinded exercise, payment or delivery.

Upon exercise, payment or delivery pursuant to an Award, the Committee may require the Participant to acknowledge the terms and conditions of the Plan and to certify on a form acceptable to the Committee, that he or she is in compliance with the terms and conditions of the Plan.

Nothing herein shall be interpreted to limit the obligations of a Participant under his or her employee agreement or any other agreement with Olin.

Notwithstanding any provision to the contrary in this Plan or any applicable Award Agreement and except as otherwise provided in this Section 9, all outstanding Options, Restricted Stock and other equity Awards held by Participant (other than any Performance Shares), regardless of whether granted before, at or after the Change in Control, shall not automatically become fully vested and immediately exercisable and, instead, each such Award shall continue to vest in accordance with its terms following a Change in Control.

Except as the Board or the Committee may expressly provide otherwise prior to a Change in Control , in the event of a Qualifying Termination upon or following a Change in Control:

all Options and Stock Appreciation Rights then outstanding shall become immediately and fully exercisable, notwithstanding any provision therein for the exercise in installments; and

all restrictions and conditions of all Restricted Stock then outstanding shall be deemed satisfied as of the date of the Qualifying Termination.

Notwithstanding anything in this Plan to the contrary, all Performance Shares held by the Participant on the date of the Change in Control shall become vested and deemed earned or satisfied in full, notwithstanding that the applicable performance cycle, retention cycle or restriction conditions shall not have been completed or met. Such Performance Shares shall be paid, cash units in cash and phantom stock units in the Shares represented thereby or such other securities, property or cash as may be deliverable in respect of Shares as a result of a Change in Control, to the Participant no later than ten (10) business days following such Change in Control.

In the event that a Participant participates or agrees to participate by loan or equity investment (other than through ownership of less than 1% of publicly traded securities of another company) in a transaction which would result in an event described in subsections (i) or (ii) of the definition of Change in Control, Participant must promptly disclose such participation or agreement to Olin, and such transaction will not be considered a Change in Control with respect to Participant for purposes of this Plan.

Following a Change in Control, no action shall be taken under the Plan that will cause any Award that has previously been determined to be (or is determined to be) subject to Code Section 409A to fail to comply in any respect with Code Section 409A without the written consent of Participant.
