Olin Corporation 2026 Long Term Incentive Plan

On April 30, 2026, Olin Corporation’s (the “Corporation”) shareholders approved the Olin Corporation 2026 Long Term Incentive Plan (the “2026 LTIP”) at the Corporation’s annual meeting of shareholders. The 2026 LTIP is effective immediately. The material terms of the 2026 LTIP were previously reported in the Corporation’s Proxy Statement dated March 20, 2026, under the caption “Item 2: Proposal to Approve the Olin Corporation 2026 Long Term Incentive Plan.” The 2026 LTIP authorizes the Compensation Committee (the “Compensation Committee”) of the Corporation’s Board of Directors (the “Board”) to grant equity compensation to non-employee directors, officers, key employees, and others as more fully described and summarized in the Proxy Statement.

Attached as Exhibit 10.1 and incorporated by reference is the 2026 LTIP.

Award Agreements

In connection with the approval of the 2026 LTIP, the Compensation Committee approved forms of award agreements for use under the 2026 LTIP, including a: (i) form of Director Stock Grant Notice and Award Agreement, (ii) form of Restricted Stock Unit Grant Notice and Award Agreement, (iii) form of Performance Share Unit Grant Notice and Award Agreement and (iv) form of Non‑Qualified Stock Option Grant Notice and Award Agreement (collectively, the “Award Agreements”).

The Director Stock Award Agreement generally provides for the grant of fully vested shares of the Corporation’s common stock (“Shares”) to non‑employee directors under the 2026 LTIP. Each Share represents a single issued and outstanding share of the Corporation’s common stock. The Shares are fully vested on the grant date and are not subject to continued service‑based vesting requirements. Issuance and delivery of the Shares are subject to compliance with applicable securities laws, stock exchange rules, and Corporation policies, and may be effected on a non‑certificated basis. The Shares do not involve deferred vesting or settlement mechanics, and no trust or separate fund is established in connection with the award.

The Restricted Stock Unit Award Agreement generally provides for the grant of time‑based restricted stock units (“RSUs”) to officers, including named executive officers, key employees, and others, under the 2026 LTIP. Each RSU represents the right to receive one share of the Corporation’s common stock upon vesting. The RSUs vest in equal annual installments over a three‑year period following the grant date, subject to the participant’s continued employment through the applicable vesting dates. Vesting of the RSUs may accelerate in the event of termination of employment due to death or disability, and certain vesting provisions apply in connection with retirement based on the participant’s age and years of service in combination with whether the first tranche has vested. In addition, following a change in control of the Corporation, RSUs generally continue to vest in accordance with their original terms, with accelerated vesting upon a qualifying termination within two years following the change in control. Recipients of RSUs are entitled to dividend equivalents from and after the grant date, which are payable in cash upon settlement of vested RSUs. RSUs do not carry voting rights prior to settlement, and the underlying shares may not be transferred or disposed of until issued upon vesting. The number of RSUs granted represents a fixed number of RSUs specified in the applicable award agreement, which vest solely based on continued service.

The Performance Share Unit Award Agreement generally provides for the grant of target performance share units (“PSUs”) to officers, including named executive officers, key employees, and others, under the 2026 LTIP. The vesting of these PSUs is tied to (i) the level of achievement of the Adjusted EBITDA Goals for each covered year and (ii) relative total shareholder return (“TSR”) performance, as established by the Compensation Committee. The PSUs contemplate a minimum payout of 0% and a maximum payout of 240% based upon the level of performance of each performance condition during the three-year measurement period. The PSUs will

vest in entirety upon completion of the three-year performance cycle, assuming continuous employment through such vesting dates, provided that vesting may accelerate upon a qualifying termination within two years following a change in control of the Corporation. Recipients of PSUs are entitled to dividend equivalents from and after the grant date, which are payable in cash upon settlement of vested and earned PSUs. The number of granted PSUs granted represents a target number of PSUs specified in the applicable award agreement, which may be earned based on the achievement of pre‑established performance objectives over the applicable performance cycle.

The Non-Qualified Stock Option Award Agreement generally provides for the grant of non‑qualified stock options (“Stock Options”) to officers, including named executive officers, key employees, and others, under the 2026 LTIP. Each Stock Option represents the right to purchase one share of the Corporation’s common stock at an exercise price equal to the fair market value of the Corporation’s common stock on the applicable grant date. The Stock Options vest in equal annual installments over a three‑year period following the grant date, subject to the participant’s continued employment through the applicable vesting dates, and have a term of ten years from the grant date. Vested Stock Options may be exercised prior to expiration in accordance with the terms of the award agreement and the 2026 LTIP. Unvested Stock Options are generally forfeited upon termination of employment, except in certain circumstances. In the event of termination due to death, unvested Stock Options generally vest in full, and vested Stock Options remain exercisable for the remainder of the option term. In the event of retirement or termination without cause, vested Stock Options generally remain exercisable for a specified post‑termination period. Following a change in control of the Corporation, Stock Options generally continue to vest in accordance with their original terms, with accelerated vesting and two year exercisability period upon a qualifying termination within two years following the change in control. In no event do our award continuation provisions allow any Stock Options to be exercised past their original expiration date. Stock Options do not entitle the holder to any rights as a shareholder, including dividend or voting rights, unless and until the Stock Option is exercised and shares of common stock are issued.

The foregoing description is only a summary of the terms of the respective awards and is qualified in its entirety by reference to the full text of the applicable Award Agreements which are filed as Exhibits 10.2, 10.3, 10.4, and 10.5 to this Current Report on Form 8-K and incorporated herein by reference.

Item 5.03.    Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year.

On April 30, 2026, the Board approved an amendment to Article II, Section 1 of Olin’s Bylaws to decrease the size of the Board from nine to eight directors, following the completion of Mr. W.

(vi)    any proxy (other than a revocable proxy given in response to a solicitation statement filed pursuant to, and in accordance with, Section 14(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), voting trust, voting agreement or similar contract, arrangement, agreement or understanding pursuant to which the Noticing Shareholder or any Associated Person, has a right to vote or direct the voting of any of the Corporation’s securities,

(vii)     any rights to dividends on the shares of the Corporation owned beneficially by the Noticing Shareholder and any Associated Person that are separated or separable from the underlying shares of the Corporation,

(viii)     any proportionate interest in shares of the Corporation or any Derivative Instruments held, directly or indirectly, by a general or limited partnership or limited liability company or similar entity in which the Noticing Shareholder or any Associated Person is a general partner or, directly or indirectly, beneficially owns an interest in a general partner, is the manager, managing member or, directly or indirectly, beneficially owns an interest in the manager or managing member of a limited liability company or similar entity, and

5

(ix)    any material interest of the Noticing Shareholder and any Associated Person, in such business; provided, however, that the disclosures described in the foregoing subclauses (i) through (x) shall not include any such disclosures with respect to the ordinary course business activities of any Exempt Party.

(c)    In addition to the information required pursuant to the foregoing provisions of this Section 9, the Corporation may require any Noticing Shareholder to furnish such other information that would reasonably be expected to be material to a reasonable shareholder’s understanding of (1) any item of business proposed by such Noticing Shareholder under this Section 9, or (2) the solicitation of proxies from the Corporation’s shareholders by the Noticing Shareholder (or any Associated Person). If requested by the Corporation, any supplemental information required under this paragraph shall be provided by a Noticing Shareholder within 10 days after it has been requested by the Corporation.

(d)    The Noticing Shareholder shall (1) notify the Corporation of any inaccuracy or change (within two business days of becoming aware of such inaccuracy or change) in any information previously provided to the Corporation pursuant to this Section 9 and (2) promptly update and supplement information previously provided to the Corporation pursuant to this Section 9, if necessary, so that the information provided or required to be provided shall be true and complete (x) as of the record date for the meeting of shareholders and (y) as of the date that is 10 calendar days prior to the meeting of shareholders or any adjournment or postponement thereof, and such update and supplement shall be delivered to the Secretary of the Corporation at the Corporation’s principal executive offices. The immediately foregoing provisions shall not be construed to extend any applicable deadlines hereunder, enable a Noticing Shareholder to change the business proposed for the meeting after the advance notice deadlines hereunder have expired or limit the Corporation’s rights with respect to any inaccuracies or other deficiencies in notices provided by a Noticing Shareholder.

(e)    Unless otherwise required by law, if the Noticing Shareholder (or a Qualified Representative of the Noticing Shareholder) does not appear at the meeting of shareholders to present such business, such proposal shall be disregarded and such business shall not be transacted, notwithstanding that the Corporation may have received proxies in respect of such vote.

(g)    Notwithstanding anything in the Bylaws to the contrary, no business shall be conducted at a meeting except in accordance with the procedures set forth in this

6

Section 9. The chair of a meeting shall, if the facts warrant, determine that the business was not brought before the meeting in accordance with the procedures prescribed by this Section 9. If the chair of the meeting should so determine, he or she shall so declare to the meeting, and the business not properly brought before the meeting shall not be transacted. Notwithstanding the foregoing provisions of this Section 9, a shareholder seeking to have a proposal included in the Corporation’s proxy statement shall, in order to do so, comply with the requirements of Regulation 14A under the Exchange Act (including Rule 14a-8 or its successor provision).

(h)    For purposes of these Bylaws:

(i)    “Affiliate” and “Associate” each shall have the respective meanings set forth in Rule 12b-2 under the Exchange Act,

(iii)    “beneficial owner” or “beneficially owned” shall have the meaning set forth for such terms in Section 13(d) of the Exchange Act,

(iv)    “Exempt Party” shall mean any depositary or any broker, dealer, commercial bank, trust company or other nominee who is a Noticing Shareholder solely as a result of being the shareholder directed to prepare and submit the notice required by these Bylaws on behalf of a beneficial owner (any such entity, an “Exempt Shareholder”),

(v)    “Noticing Shareholder” shall mean the shareholder giving notice with respect to proposed business pursuant to Section 9 of Article I of these Bylaws or with respect to nominations for the election of directors pursuant to Section 1 of Article II of these Bylaws, and

(vi)    “Qualified Representative” of a Noticing Shareholder shall mean (1) a duly authorized officer, manager or partner of such Noticing Shareholder or (2) a person authorized by a writing executed by such Noticing Shareholder (or a reliable reproduction or electronic transmission of the writing) delivered by such Noticing Shareholder to the Corporation prior to the making of any nomination or proposal at a

7

shareholder meeting stating that such person is authorized to act for such Noticing Shareholder as proxy at the meeting of shareholders, which writing or electronic transmission, or a reliable reproduction of the writing or electronic transmission, must be produced at the meeting of shareholders.

Section 10. Special Meeting at Request of Shareholders.

(a)    Any one or more holders of record of a majority of the issued and outstanding stock of the Corporation entitled to vote requesting the Corporation to call a special meeting of shareholders pursuant to Section 2 of Article VIII of the Articles (collectively, the “Initiating Shareholder”) shall give written notice of such request to the Secretary of the Corporation at the Corporation’s principal executive offices (the “Notice”).

ARTICLE II.

BOARD OF DIRECTORS.

Section 1. Number, Term, Election.

(a)    The property, business and affairs of the Corporation shall be managed under the direction of the Board as from time to time constituted. The Board shall consist of eight directors, but the number of directors may be increased to any number, not more than 18 directors, or decreased to any number, not less than three directors, by amendment of these Bylaws. No director need be a shareholder. Each director shall stand for election for a term expiring at the next succeeding annual meeting of shareholders and until a successor shall have been elected and qualified or until such director’s prior death, resignation, disqualification or removal. In case the number of directors shall be increased, the additional directors to fill the vacancies caused by such increase shall be elected in accordance with the provisions of Section 4 of Article VI of these Bylaws. No person shall be eligible for election or appointment as a director unless such person has, within 10 days following any reasonable request therefor from the Board or any committee thereof, made himself or herself available to be interviewed by the Board (or any committee or other subset thereof) with respect to such person’s qualifications to serve as a director or any other matter reasonably related to such person’s candidacy or service as a director of the Corporation.

(b)    Except as provided in the following paragraph, each director shall be elected by a vote of the majority of the votes cast with respect to that director-nominee’s election at a meeting for the election of directors at which a quorum is present. For purposes of this Section 1, a majority of the votes cast means that the number of shares voted “for” a director must exceed the number of shares voted “against” that director.

The foregoing paragraph shall not apply to any election of directors if there are more nominees for election than the number of directors to be elected, one or more of whom are properly proposed by shareholders, as of the last applicable date on which a shareholder may give proper notice of a nomination of a director pursuant to this Section 1. A nominee for director in an election to which this paragraph applies shall be elected by a plurality of the votes cast in such election.

(c)    Subject to the rights of holders of any preferred stock outstanding, nominations for the election of directors may be made by the Board or a committee appointed by the Board (each such nominee, a “Board Nominee”) or by any shareholder entitled to vote in the election of directors generally (each such nominee, a “Shareholder Nominee”). However, any shareholder entitled to vote in the election of directors generally may nominate one or more persons for election as directors at a meeting only if written notice of such shareholder’s intent to make such nomination or nominations has been given, either by personal delivery or by United States registered or certified mail, postage prepaid, to the Secretary of the Corporation, with respect to an annual meeting, (i) not later than 120 calendar days, or earlier than 150 calendar days, before the anniversary of the immediately preceding annual meeting or (ii) if no annual meeting

9

was held in the previous year or the date of the annual meeting is more than 30 calendar days before or more than 60 calendar days after such anniversary date, not later than the 90th calendar day prior to such annual meeting of shareholders or, if later, the 10th calendar day following the date on which public disclosure of the date of such annual meeting of shareholders is first made, or, with respect to any special meeting of shareholders called for the election of directors by the Board, not later than the seventh calendar day following the date on which notice of such meeting is first given to shareholders. Each such notice shall set forth:

(i)    the name and address, as they appear on the Corporation’s stock transfer books, of the Noticing Shareholder giving the notice and the name and address of any Associated Person,

(ii)    a representation that such Noticing Shareholder is a shareholder of record and intends to appear in person or by proxy at such meeting to nominate the person or persons specified in the notice,

(v)    any proxy (other than a revocable proxy given in response to a solicitation statement filed pursuant to, and in accordance with, Section 14(a) of the Exchange Act), voting trust, voting agreement or similar contract, arrangement, agreement or understanding pursuant to which the Noticing Shareholder or any Associated Person, has a right to vote or direct the voting of any of the Corporation’s securities,

(vi)     any rights to dividends on the shares of the Corporation owned beneficially by the Noticing Shareholder and any Associated Person that are separated or separable from the underlying shares of the Corporation,

(vii)    any proportionate interest in shares of the Corporation or any Derivative Instruments held, directly or indirectly, by a general or limited partnership or limited liability company or similar entity in which the Noticing Shareholder or any

10

Associated Person is a general partner or, directly or indirectly, beneficially owns an interest in a general partner, is the manager, managing member or, directly or indirectly, beneficially owns an interest in the manager or managing member of a limited liability company or similar entity,

(viii)    a description of all agreements, arrangements and understandings between such Noticing Shareholder or any Associated Person and each Shareholder Nominee with respect to such Shareholder Nominee’s service or duties as a nominee or director of the Corporation, including any direct or indirect confidentiality, compensation, reimbursement or indemnification arrangement in connection with such Shareholder Nominee’s service or action as a nominee or director of the Corporation or any commitment or assurance as to how such Shareholder Nominee will act or vote on any matter, and

(ix)    the information that would be required to be set forth in a Schedule 13D filed pursuant to Rule 13d-1(a) or an amendment pursuant to Rule 13d-2(a) if such statement were required to be filed under the Exchange Act and the rules and regulations promulgated thereunder by such Noticing Shareholder and any beneficial owner on whose behalf the notice is given; provided, however, that the disclosures described in the foregoing subclauses (i) through (ix) shall not include any such disclosures with respect to the ordinary course business activities of any Exempt Party.

(d)    Each such Noticing Shareholder’s notice pursuant to this Section 1 shall also set forth:

(i)    the name, age, business address and, if known, residence address of each Shareholder Nominee for whom the Noticing Shareholder is proposing or intends to solicit proxies and of each Shareholder Nominee who would be presented for election at the annual meeting in the event of a need to change the Noticing Shareholder’s original slate,

(e)    In addition to the information required pursuant to the foregoing provisions of this Section 1, the Corporation may require any Noticing Shareholder to furnish such other information that would reasonably be expected to be material to a reasonable shareholder’s understanding of (1) the solicitation of proxies from the Corporation’s shareholders by the Noticing Shareholder (or any Associated Person), or (2) the eligibility, suitability or qualifications of a Shareholder Nominee to serve as a director of the Corporation or the independence, or lack thereof, of such Proposed Nominee, under the listing standards of each securities exchange upon which the Corporation’s securities are listed, any applicable rules of the SEC, any publicly disclosed standards used by the Board in selecting nominees for election as a director and for determining and disclosing the independence of the Corporation’s directors, including those applicable to a director’s service on any of the committees of the Board, or the requirements of any other laws or regulations applicable to the Corporation. If requested by the Corporation, any supplemental information required under this paragraph shall be provided by a Noticing Shareholder within 10 days after it has been requested by the Corporation.

(f)    The Noticing Shareholder shall (1) notify the Corporation of any inaccuracy or change (within two business days of becoming aware of such inaccuracy or change) in any information previously provided to the Corporation pursuant to this Section 1 and (2) promptly update and supplement information previously provided to the Corporation pursuant to this Section 1, if necessary, so that the information provided or required to be provided shall be true and complete (x) as of the record date for the meeting and (y) as of the date that is 10 calendar days prior to the meeting or any adjournment or postponement thereof, and such update and supplement shall be delivered to the Secretary of the Corporation at the Corporation’s principal executive offices.

(g)    In addition to the other requirements of this Section 1 with respect to any nomination proposed by a shareholder to be made at a meeting, the Noticing Shareholder and each Associated Person shall also comply with all applicable requirements of the Articles, these Bylaws and state and federal law, including the Exchange Act (including Rule 14a-19 thereunder), with respect to any such nomination

12

or the solicitation of proxies with respect thereto. In addition to the other requirements of this Section 1, unless otherwise required by law, (i) no Noticing Shareholder or Associated Person shall solicit proxies in support of any nominees other than Board Nominees unless such Noticing Shareholder and Associated Person have complied with Rule 14a-19 under the Exchange Act in connection with the solicitation of such proxies, including the provision to the Corporation of notices required thereunder in a timely manner, and (ii) if such Noticing Shareholder or Associated Person (1) provides notice pursuant to Rule 14a-19(b) under the Exchange Act and (2) subsequently fails to comply with any of the requirements of Rule 14a-19 under the Exchange Act, then the Corporation shall disregard any proxies or votes solicited for such Noticing Shareholder’s nominees. Upon request by the Corporation, if any Noticing Shareholder or Associated Person provides notice pursuant to Rule 14a-19(b) under the Exchange Act, such Noticing Shareholder or Associated Person shall deliver to the Corporation, no later than five business days prior to the applicable meeting, reasonable evidence that such Noticing Shareholder or Associated Person has met the requirements of Rule 14a-19 under the Exchange Act.

(h)    The immediately foregoing provisions shall not be construed to extend any applicable deadlines hereunder, enable a Noticing Shareholder to change the person or persons specified in the notice for election as director after the advance notice deadlines hereunder have expired or limit the Corporation’s rights with respect to any inaccuracies or other deficiencies in notices provided by a Noticing Shareholder. The Secretary of the Corporation shall deliver each Noticing Shareholder’s notice under this Section 1 that has been timely received to the Board or a committee designated by the Board for review.

(i)    Unless otherwise required by law, if the Noticing Shareholder (or a Qualified Representative of the Noticing Shareholder) does not appear at the meeting of shareholders to nominate the individual set forth in the Noticing Shareholder’s notice of nomination as a director, such nomination shall be disregarded, notwithstanding that the Corporation may have received proxies in respect of such vote.

(j)    In addition to the information required to be provided by shareholders pursuant to this Section 1, the following information shall be provided to the Secretary by the Noticing Shareholder and/or each Shareholder Nominee:

(i)    a completed copy of the Corporation’s form of director’s questionnaire and a written consent of the Shareholder Nominee to the Corporation following such processes for evaluation of such nominee as the Corporation follows in evaluating any person being considered for nomination to the Board of Directors, in the form to be provided by the Secretary within 10 days after receiving a written request therefor from any shareholder of record identified by name;

(ii)    the Shareholder Nominee’s agreement to comply with the Corporation’s corporate governance, conflict of interest, confidentiality, share ownership

13

and share trading policies, as provided by the Secretary within 10 days after receiving a written request therefor from any shareholder of record identified by name;

(iii)    written confirmation that the Shareholder Nominee (A) does not have, and will not have or enter into, any agreement, arrangement or understanding as to how he or she will vote on any matter, if elected as a director of the Corporation, and (B) is not a party to, and will not become a party to, any agreement, arrangement or understanding with any person or entity, including any direct or indirect compensation, reimbursement or indemnification arrangement with any person or entity other than the Corporation in connection with such nominee’s service or action as a director of the Corporation the terms of which have not been fully disclosed in advance to the Secretary of the Corporation;

(iv)    written disclosure of any transactions between the Noticing Shareholder and the Shareholder Nominee within the preceding five years; and

(v)    any additional information as necessary to permit the Board to determine if each Shareholder Nominee is independent under applicable listing standards with respect to service on the Board or any committee thereof, under any applicable rules of the SEC, and under any publicly disclosed standards used by the Board of Directors in determining and disclosing the independence and qualifications of the Corporation’s directors.

(k)    Notwithstanding anything in the Bylaws to the contrary, no nomination for the election of a director shall be considered and voted upon at a meeting except in accordance with the procedures set forth in this Section 1. The chair of a meeting shall, if the facts warrant, determine that a nomination for the election of a director was not brought before the meeting in accordance with the procedures prescribed by this Section 1. If the chair of the meeting should so determine, he or she shall so declare to the meeting, and the nomination for the election of such director not properly brought before the meeting shall not be considered and voted upon.

Section 2. Compensation. Each director, in consideration of his or her serving as such, shall be entitled to receive from the Corporation such amount per annum or such fees for attendance at Board and committee meetings, or both, in cash or other property, including securities of the Corporation, as the Board shall from time to time determine, together with reimbursements for the reasonable expenses incurred by him or her in connection with the performance of his or her duties. Nothing contained herein shall preclude any director from serving the Corporation, or any subsidiary or affiliated corporation, in any other capacity and receiving appropriate compensation therefor.

ARTICLE III.1

INDEMNIFICATION AND LIMIT ON LIABILITY.

(a)    Every person who is or was a director, officer or employee of the Corporation, or who, at the request of the Corporation, serves or has served in any such capacity with another corporation, partnership, joint venture, trust, employee benefit plan, or other enterprise shall be indemnified by the Corporation against any and all liability and reasonable expense that may be incurred by him or her in connection with or resulting from any claim, action or proceeding (whether brought in the right of the Corporation or any such other corporation, entity, plan or otherwise), civil or criminal, in which he or she may become involved, as a party or otherwise, by reason of his or her being or having been a director, officer or employee of the Corporation, or such other corporation, entity or plan while serving at the request of the Corporation, whether or not he or she continues to be such at the time such liability or expense shall have been incurred, unless such person engaged in willful misconduct or a knowing violation of the criminal law.

As used in this Article III: (i) the terms “liability” and “expense” shall include, but shall not be limited to, counsel fees and disbursements and amounts of judgments, fines or penalties against, and amounts paid in settlement by, a director, officer or employee; (ii) the terms “director,” “officer” and “employee,” unless the context otherwise requires,

1 Compiler’s Note: This Article III was adopted by the shareholders at the Annual Meeting of Shareholders, April 28, 1994.

16

include the estate or personal representative of any such person; (iii) a person is considered to be serving an employee benefit plan as a director, officer or employee of the plan at the Corporation’s request if his or her duties to the Corporation also impose duties on, or otherwise involve services by, him or her to the plan or, in connection with the plan, to participants in or beneficiaries of the plan; (iv) the term “occurrence” means any act or failure to act, actual or alleged, giving rise to a claim, action or proceeding; and (v) service as a trustee or as a member of a management or similar committee of a partnership or joint venture shall be considered service as a director, officer or employee of the trust, partnership or joint venture.

The termination of any claim, action or proceeding, civil or criminal, by judgment, settlement, conviction or upon a plea of nolo contendere, or its equivalent, shall not create a presumption that a director, officer or employee did not meet the standards of conduct set forth in this paragraph (a). The burden of proof shall be on the Corporation to establish, by a preponderance of the evidence, that the relevant standards of conduct set forth in this paragraph (a) have not been met.

(b)    Any indemnification under paragraph (a) of this Article shall be made unless (i) the Board, acting by a majority vote of those directors who were directors at the time of the occurrence giving rise to the claim, action or proceeding involved and who are not at the time parties to such claim, action or proceeding (provided there are at least five such directors), finds that the director, officer or employee has not met the relevant standards of conduct set forth in such paragraph (a), or (ii) if there are not at least five such directors, the Corporation’s principal Virginia legal counsel, as last designated by the Board as such prior to the time of the occurrence giving rise to the claim, action or proceeding involved, or in the event for any reason such Virginia counsel is unwilling to so serve, then Virginia legal counsel mutually acceptable to the Corporation and the person seeking indemnification, deliver to the Corporation their written advice that, in their opinion, such standards have not been met.

(c)    Expenses incurred with respect to any claim, action or proceeding of the character described in paragraph (a) shall, except as otherwise set forth in this paragraph (c), be advanced by the Corporation prior to the final disposition thereof upon receipt of an undertaking by or on behalf of the recipient to repay such amount if it is ultimately determined that he or she is not entitled to indemnification under this Article III. No security shall be required for such undertaking and such undertaking shall be accepted without reference to the recipient’s financial ability to make repayment. Notwithstanding the foregoing, the Corporation may refrain from, or suspend, payment of expenses in advance if at any time before delivery of the final finding described in paragraph (b), the Board or Virginia legal counsel, as the case may be, acting in accordance with the procedures set forth in paragraph (b), find by a preponderance of the evidence then available that the officer, director or employee has not met the relevant standards of conduct set forth in paragraph (a).

17

(d)    No amendment or repeal of this Article III shall adversely affect or deny to any director, officer or employee the rights of indemnification provided in this Article III with respect to any liability or expense arising out of a claim, action or proceeding based in whole or substantial part on an occurrence the inception of which takes place before or while this Article III, as adopted by the shareholders of the Corporation at the 1986 Annual Meeting of the Corporation, is in effect. The provisions of this paragraph (d) shall apply to any such claim, action or proceeding whenever commenced, including any such claim, action or proceeding commenced after any amendment or repeal to this Article III.

(e)    The rights of indemnification provided in this Article III shall be in addition to any rights to which any such director, officer or employee may otherwise be entitled by contraction or as a matter of law.

(f)    In any proceeding brought by or in the right of the Corporation or brought by or on behalf of shareholders of the Corporation, no director or officer of the Corporation shall be liable to the Corporation or its shareholders for monetary damages with respect to any transaction, occurrence or course of conduct, whether prior or subsequent to the effective date of this Article lll, except for liability resulting from such person’s having engaged in willful misconduct or a knowing violation of the criminal law or any federal or state securities law.

(g)    An amendment to this Article III shall be approved only by a majority of the votes entitled to be cast by each voting group entitled to vote thereon.

This Plan supersedes the Olin Corporation 2021 Long Term Incentive Plan (“2021 Plan”), the Olin Corporation 2018 Long Term Incentive Plan (“2018 Plan”), the Olin Corporation 2016 Long Term Incentive Plan (“2016 Plan”), the Olin Corporation 2014 Long Term Incentive Plan (“2014 Plan”), the Olin Corporation 2009 Long Term Incentive Plan (“2009 Plan”), the Olin Corporation 2003 Long Term Incentive Plan (“2003 Plan”), and the 1997 Stock Plan for Non-Employee Directors (“1997 Plan”) (and collectively the 2021 Plan, 2018 Plan, 2016 Plan, 2014 Plan, 2009 Plan, 2003 Plan, and 1997 Plan, the “Prior Plans”) as of the Effective Date. On and after the Effective Date, no new awards shall be granted under the Prior Plans, although outstanding awards previously granted under the Prior Plans prior to the Effective Date shall continue to be governed by the terms of the applicable Prior Plan.

Section 6.    Awards.

(a)Options. The Committee is authorized to grant Options to Participants with the following terms and conditions and with such additional terms and conditions, not inconsistent with the provisions of the Plan, as the Committee shall determine:

(i)Exercise Price. The per Share exercise price shall be determined by the Committee, provided that such exercise price shall not be less than the Fair Market Value of a Share on the date of the Option grant.

(ii)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.

(iii)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. The full exercise price for Shares purchased upon the exercise of any Option shall be paid at the time of such exercise (except that, in the case of an exercise arrangement approved by

7

the Committee and described below, payment may be made as soon as practicable after the exercise). The exercise price shall be payable in cash or, unless the Committee prohibits it, 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.

(iv)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. Incentive Stock Options shall not be granted to Non-Employee Directors.

(b)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. Subject to the terms of the Plan and any applicable Award Agreement, the exercise price, term, methods of exercise, methods of payment or settlement, including whether such SAR shall be paid in cash or Shares, and any other terms and conditions of any Stock Appreciation Right shall be as determined by the Committee, provided that in no event shall the term of a Stock Appreciation Right exceed a period of ten years from the date of its grant.

(c)Restricted Stock, Restricted Stock Unit, and Performance Share Awards.

(i)Issuance. The Committee is authorized to grant Awards of Restricted Stock, Restricted Stock Units and Performance Shares to Participants. The Committee may make such Awards in such amounts and subject to such terms and conditions, as the Committee shall determine. Such Awards may involve the transfer of actual Shares to Participants, or payment in cash or otherwise of amounts based on the value of Shares and may include, without limitation, Awards designed to comply with or take advantage of the applicable local laws of jurisdictions other than the United States.

(ii)Restrictions. Any such Award shall be subject to such conditions, restrictions and contingencies as the Committee may impose (including, without limitation, any limitation

8

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.

(d)Other Awards.

(i)Issuance. The Committee is authorized to grant other Awards to Participants. The Committee may make such Other Stock-Based Awards in such amounts and subject to such terms and conditions, as the Committee shall determine. Such Awards may involve the transfer of actual Shares to Participants, or payment in cash or otherwise of amounts based on the value of Shares and may include, without limitation, Awards designed to comply with or take advantage of the applicable local laws of jurisdictions other than the United States.

(ii)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 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.

(e)Cash Bonus Awards. The Committee shall have the authority to make an Award of a cash bonus to any Participant. Any such Award may be subject to a performance period, performance goals or such other terms and conditions as the Committee may designate in the applicable Award Agreement.

Section 7.    Forms of Payment Under Awards.

Subject to the terms of the Plan and of any applicable Award Agreement, including Section 6(a)(iii) above, payments to be made by Olin or an Affiliate upon the grant, exercise, or payment of an Award may be made in such form or forms as the Committee shall determine, including, without limitation, cash, Shares, other securities, other Awards, or other property or any combination thereof, and may be made in a single payment or transfer, in each case in accordance with rules and procedures established by the Committee and in accordance with Code Section 409A to the extent applicable.

Section 8.    Dividends and Dividend Equivalents.

An Award (other than Options or Stock Appreciation Rights) may provide the Participant with the right to receive dividends or dividend equivalent payments with respect to Shares subject to the Award which may be settled in cash or Shares as determined by the Committee; provided, however, that such dividends or dividend equivalents shall be subject to the same vesting restrictions, including any service and performance conditions as the underlying Award. Any such settlements, and any such crediting of dividends or dividend equivalents or reinvestment in Shares, may be subject to such additional conditions, restrictions and contingencies as the Committee shall establish. Notwithstanding the foregoing, a Participant who is entitled to dividends or dividend equivalents shall not be entitled to receive a special or extraordinary dividend or distribution unless the Committee shall have expressly authorized such receipt.

In no event shall dividends or dividend equivalents (whether paid in cash or Shares) be paid with respect to any Options or any Stock Appreciation Rights.

9

Section 9.    Additional Conditions to Enjoyment of Awards.

A Participant may be required to enter into a restrictive covenants agreement in a form provided by the Company or an Affiliate as a condition to receipt of an Award.

Section 10.    Forfeiture Events.

(a)Termination for Cause / Violation of Restrictive Covenants. Unless otherwise specified in the applicable Award Agreement or policies adopted by the Compensation Committee, in the event the employment of a Participant to whom an Award has been granted under the Plan shall be terminated by Olin or an Affiliate with Cause or the applicable Participant violates any restrictive covenants entered into by the Participant and the Company or an Affiliate, any outstanding Award, including both vested and unvested portions and any dividends and dividend equivalents attributable thereto, shall be immediately forfeited and deemed null and void as of the date of such termination of employment.

(b)Other Termination of Employment. Unless otherwise specified in the applicable Award Agreement or policies adopted by the Compensation Committee, in the event the employment of a Participant to whom an Award has been granted under the Plan shall be terminated by Olin or an Affiliate or by a Participant for any reason other than a termination by Olin or an Affiliate with Cause:

(i)The unvested portion of the terminated Participant’s Award(s), including any dividends and dividend equivalents attributable thereto, shall be immediately forfeited and deemed null and void as of the date of such termination of employment; and

(ii)Any vested Option held by the Participant may be exercised at any time within three months after such termination (which three-month period may be extended by the Committee), but in no event shall such three-month period or any such extension permit the exercise of an Option after the expiration date of the Option.

Awards granted under the Plan shall not be affected by any change of duties or position so long as the Participant continues to be an Employee.

(c)Other Forfeitures. For the avoidance of doubt, the Committee may specify in an Award Agreement that the Participant’s rights, payments and benefits with respect to an Award shall be subject to reduction, cancellation, acceleration, forfeiture or recoupment upon the occurrence of certain specified events, in addition to any otherwise applicable vesting or performance conditions of an Award.

Section 11.    Change in Control.

(a)General Rule. The provisions of this Section 11 shall apply in the case of a Change in Control, unless otherwise provided in the Award Agreement, the operative transaction agreements related to the Change in Control, or any separate agreement with a Participant governing an Award.

(b)Discretion to Cash Out Awards. In the event of a Change in Control, the Committee may in its discretion, cancel any outstanding vested Awards and pay to the holders thereof, in cash or

10

stock, or any combination thereof, the value of such vested Awards based upon the price per Share received or to be received by other shareholders of Olin upon such Change in Control.

(c)Assumption of Awards. In the event of a Change in Control, the surviving, continuing, successor, or purchasing corporation or other business entity or parent thereof, as the case may be (the “Acquiror”), may, without the consent of any Participant, assume or continue Olin’s rights and obligations under each or any Award or portion thereof outstanding immediately prior to the Change in Control or substitute for each or any such outstanding Award or portion thereof a substantially equivalent award with respect to the Acquiror’s stock, as applicable. For purposes of this Section, if so determined by the Committee in its discretion, an Award denominated in Shares shall be deemed assumed if, following the Change in Control, the Award confers the right to receive, subject to the terms and conditions of the Plan and the applicable Award Agreement, for each Share subject to the Award immediately prior to the Change in Control, the consideration (whether stock, cash, other securities or property or a combination thereof) to which a holder of a Share on the effective date of the Change in Control was entitled (and if holders were offered a choice of consideration, the type of consideration chosen by the holders of a majority of the outstanding Shares); provided, however, that if such consideration is not solely common stock of the Acquiror, the Committee may, with the consent of the Acquiror, provide for the consideration to be received upon the exercise or settlement of the Award, for each Share subject to the Award, to consist solely of common stock of the Acquiror equal in Fair Market Value to the per Share consideration received by holders of Shares pursuant to the Change in Control.

(d)Vesting Provisions. Unless otherwise specified in the applicable Award Agreement or policies adopted by the Compensation Committee, (i) any Award or portion thereof which is not assumed, continued or substituted as provided herein by the Acquiror in connection with the Change in Control, irrespective of the vesting schedule, shall become fully vested (with any performance conditions considered achieved at target levels) and immediately exercisable and, if applicable, the restricted period shall end as of the time of consummation of the Change in Control and (ii) any Award or portion thereof which is assumed, continued or substituted as provided herein by the Acquiror in connection with the Change in Control, irrespective of the vesting schedule, shall become fully vested (with any performance conditions considered achieved at target levels) and immediately exercisable and, if applicable, the restricted period shall end as of the time of consummation of the Change in Control upon a Participant’s Qualifying Termination.

(e)Golden Parachute Payments. In the event any payment(s) or the value of any benefit(s) received or to be received by a Participant in connection with or contingent upon a Change in Control (whether received or to be received pursuant to the terms of the Plan or any Award Agreement or of any other plan, arrangement or agreement of the Company, its successors, any person whose actions result in a Change in Control, or any person affiliated with any of them (or which, as a result of the completion of the transaction(s) causing a Change in Control, will become affiliated with any of them) (collectively, the “Payments”)), are determined, under the provisions of this subsection to be subject to an excise tax imposed by Code Section 4999 (any such excise tax, together with any interest and penalties, are hereinafter collectively referred to as the “Excise Tax”), as determined in this subsection, then the Company shall reduce the aggregate amount of the Payments payable to the Participant such that no Excise Tax shall be payable by the Participant and the Payments shall not cease to be deductible by the Company by reason of Code Section 280G (or any successor provision thereto). Notwithstanding the foregoing, the Company shall not reduce the

11

aggregate amount of the Payments payable to the Participant pursuant to the foregoing sentence if the After-Tax Amount (as defined below) of the unreduced Payments is greater than the After-Tax Amount that would have been paid had the Payments been reduced pursuant to the foregoing sentence. For purposes of this Agreement “After-Tax Amount” means the portion of a specified amount that would remain after payment of all Excise Taxes (if any), income taxes, payroll and withholding taxes, and other applicable taxes paid or payable by Participant in respect of such specified amount. Any reductions shall be made in a manner intended to comply with Section 409A of the Code.

Section 12.    Amendment and Termination.

(a)Amendments to the Plan. The Committee may amend, suspend, discontinue or terminate the Plan at any time; provided that, (i) no amendment that would require approval of Olin’s shareholders under any applicable law, regulation or rule, including the rules of any stock exchange or quotation system upon which the Shares may then be listed or quoted shall be made without obtaining such shareholder approval and (ii) no amendment, suspension, discontinuance or termination may apply to the terms of any outstanding Award (contingent or otherwise) granted prior to the effective date of such amendment, suspension, discontinuance or termination, in a manner which would reasonably be considered to be adverse to the Participant, without the Participant’s consent.

(b)Amendments to Awards. The Committee may waive any conditions or rights with respect to, or amend, alter, suspend, discontinue, or terminate, any unexercised or unvested 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, discontinuance or termination may apply to the terms of any outstanding Award (contingent or otherwise) granted prior to the effective date of such amendment, suspension or termination, in a manner which would reasonably be considered to be adverse to the Participant, without the Participant’s consent.

(c)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(c) 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.

(d)Successors. All obligations of Olin under the Plan, with respect to any Awards granted hereunder, shall be binding on any successor to Olin, whether the existence of such successor is the result of a direct or indirect purchase, merger, consolidation or otherwise, of all or substantially all of the business and/or assets of Olin.

Section 13.    General Provisions.

(a)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

12

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.

(b)Compliance with Applicable Laws. 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.

(c)No Lien or Security Interest. No Award (other than Released Securities), and no right under any such Award, may be pledged, attached or otherwise encumbered other than in favor of Olin, and any purported pledge, attachment, or encumbrance thereof other than in favor of Olin shall be void and unenforceable against Olin or any Affiliate.

(d)Limits on Transfer of Awards. No Award (other than Released Securities) or right thereunder shall be assignable or transferable by a Participant, other than: (i) by will or the laws of descent and distribution (or, in the case of an Award of Restricted Securities, to Olin); or (ii) in the case of Awards other than Incentive Stock Options, to the extent permitted under the terms of the Award, by a gift or domestic relations order to any Family Member, to a trust in which the Participant and/or his or her Family Members hold more than 50% of the beneficial interest, to a foundation in which the Participant and/or Family Members control the management of assets, and any other entity in which the Participant and/or his or her Family Members own more than 50% of the voting interests.

(e)Beneficiary Designations. 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 or a permitted transferee, or, if permissible under applicable law by the Participant’s guardian or legal representative.

(f)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.

(g)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.

(h)Rights of a Shareholder. No Award shall confer on any Participant any of the rights of a shareholder of Olin unless and until Shares are in fact issued to such Participant, without restriction, in connection with such Award.

13

(i)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. With respect to withholding required upon the exercise of Options or SARs, upon the lapse of restrictions on Restricted Stock and Restricted Stock Units, or upon the achievement of performance goals related to Performance Shares, or any other taxable event arising as a result of an Award granted hereunder, Participants may elect to satisfy the withholding requirement, at the Committee’s discretion, in whole or in part, by having Olin withhold Shares having a Fair Market Value on the date the tax is to be determined (A) subject to the approval of the Committee, equal to the minimum statutory total tax that could be imposed on the transaction, or (B) solely to the extent authorized by the Committee in advance, at a higher rate up to the maximum statutory total tax that could be imposed on the transaction. All such elections shall be irrevocable, made in writing, and signed by the Participant, and shall be subject to any restrictions or limitations that the Committee, in its sole discretion, deems appropriate. No opinion is expressed nor warranties made as to the tax effects under federal, foreign, state or local laws or regulations of any Award granted under the Plan. Regardless of whether Awards are intended to qualify for favorable tax treatment, Olin does not warrant or represent that such treatment will be available.

(j)Whistleblower Provisions. Nothing contained herein prohibits the Participant from: (i) reporting possible violations of federal law or regulations, including any possible securities laws violations, to any governmental agency or entity, (ii) making any other disclosures that are protected under the whistleblower provisions of federal law or regulations, or (iii) otherwise fully participating in any federal whistleblower programs, including but not limited to any such programs managed by the U.S. Securities and Exchange.

(k)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 Missouri, excluding any conflicts or choice of law rule or principle that might otherwise refer construction or interpretation of this Plan or any Award Agreement to the substantive law of another jurisdiction. Any legal action against the Plan, Olin, an Affiliate, or the Committee may only be brought in the Circuit Court in St. Louis County and/or the United States District Court in St. Louis, Missouri.

(l)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.

(m)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.

14

(n)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. 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.

(o)Award Agreement. The terms of any plan or guideline adopted by the Committee and applicable to an Award shall be deemed incorporated in and a part of the related Award Agreement. The Committee may provide for the use of electronic, internet or other non-paper Award Agreements, and the use of electronic, internet or other non-paper means for the Participant’s acceptance of, or actions under, an Award Agreement. 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.

(p)Olin Policies. Notwithstanding any other provisions of this Plan, (i) all Awards will be subject to any Company policy that Olin or an Affiliate may adopt and/or amend from time to time regarding the hedging or pledging (or any similar transaction) of Company securities and (ii) all Awards shall be subject to such deductions and clawback as may be required to be made pursuant to any law, government regulation or stock exchange listing requirement, or any policy adopted by Olin or an Affiliate, regardless of when such policy is adopted.

(q)409A Compliance. It is intended that the Plan (and any Award) will comply with or be exempt from Code Section 409A, and the Plan (and any Award) shall be interpreted and construed on a basis consistent with such intent. The Plan (and any Award) may be amended in any respect deemed necessary (including retroactively) by the Committee in order to preserve compliance with or exemption from Code Section 409A. The preceding shall not be construed as a guarantee of any particular tax effect for Plan benefits or Awards. A Participant (or beneficiary) is solely responsible and liable for the satisfaction of all taxes and penalties that may be imposed on the Participant (or beneficiary) in connection with any Award to such Participant (or beneficiary) under the Plan (including any taxes and penalties under Code Section 409A), and neither Olin nor any Affiliate shall have any obligation to indemnify or otherwise hold a Participant (or beneficiary) harmless from any or all of such taxes or penalties.

Section 14.    Effective Date and Term.

The Plan shall be effective as of the Effective Date and, if not terminated earlier pursuant to Section 12, shall remain in effect until the tenth anniversary of the Effective Date. In the event of a Plan termination, the Plan shall remain in effect as long as any Awards under it are outstanding; provided; however, that, to the extent required by the Code, no Incentive Stock Option may be granted under the Plan on a date that is more than ten years from the Effective Date.

Nevertheless, the tax treatment of any Award is not guaranteed, and none of the Company, its Affiliates, or their respective officers, directors, employees, consultants, agents, representatives or advisors shall be liable to the Participant or any other Person if any portion of this Agreement or any amount payable hereunder is subject to additional taxes, penalties, or interest under Section 409A of the Code or otherwise.

(a)Notwithstanding anything herein to the contrary, to the extent that any Award would constitute non-exempt “deferred compensation” for purposes of Section 409A of the Code and would be payable or distributable under this Agreement by reason of a Change in Control, or the Participant’s separation from service, such amount or benefit will not be payable or distributable to the Participant by reason of such circumstance unless the circumstances giving rise to such Change in Control or separation from service meet any description or definition of “change in control event” or “separation from service”, as the case may be, in Section 409A of the Code and applicable regulations (without giving effect to any elective provisions that may be available under such definition). This provision does not prohibit the vesting of any Award upon a change of control or separation from service, however defined. If this provision prevents the payment or distribution of any Award, such payment shall be made on the date that would have applied absent such designated event or circumstance.

(b)Notwithstanding anything herein to the contrary, if an amount payable under this Agreement constitutes non-exempt “deferred compensation” for purposes of Section 409A of the Code and would otherwise be payable by reason of a Participant’s separation from service during a period in which the Participant is a Specified Employee (as defined below), then, subject to any permissible acceleration of payment by the Committee under Treas. Reg. Section 1.409A-3(j)(4)(ii) (domestic relations order), (j)(4)(iii) (conflicts of interest), or (j)(4)(vi) (payment of employment taxes): (i) the amount of such non-exempt deferred compensation that would otherwise be payable during the six-month period immediately following the Participant’s separation from service will be accumulated through and paid or provided on the first day of the seventh month following the Participant’s separation from service (or, if the Participant dies during such period, within 30 days after the Participant’s death) (in either case, the “Required Delay Period”); and (ii) the normal payment or distribution schedule for any remaining payments or distributions will resume at the end of the Required Delay Period. For purposes hereof, the term “Specified Employee” has the meaning given such term in Code Section 409A and the final regulations thereunder, provided, however, that, as permitted in such final regulations, the Company’s Specified Employees and its application of the six-month delay rule of Code Section 409A(a)(2)(B)(i) shall be determined in accordance with rules adopted by the Committee, which shall be applied consistently with respect to all nonqualified deferred compensation arrangements of the Company, including this Agreement and the Plan.

RESTRICTED STOCK UNIT AWARD AGREEMENT

This Restricted Stock Unit Award Agreement (this “Agreement”) is made by and between the Company and the Participant specified in the accompanying Grant Notice, effective as of the Grant Date set forth in therein. References herein to this Agreement shall be deemed to include the Grant Notice unless the context clearly requires otherwise.

In consideration of the premises and covenants contained herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto, for themselves, their successors and assigns, hereby agree as follows:

1.Grant of RSUs. Effective as of the Grant Date, the Company shall grant the Participant the number of RSUs set forth in the Grant Notice. Each RSU shall represent the right to receive, upon settlement, one Share, in accordance with the terms and conditions of this Agreement and the Plan. For each RSU granted to the Participant, the Participant shall also receive a corresponding Dividend Equivalent right, subject to the terms and conditions of Section 4(b).

2.Incorporation by Reference, Etc. The provisions of the Grant Notice and the Plan are incorporated herein by reference. Any capitalized term not otherwise defined in this Agreement shall have the definition set forth in the Grant Notice or the Plan, as applicable. The Committee shall have final authority to interpret and construe this Agreement, the Grant Notice, and the Plan and to make all determinations hereunder or thereunder, and the Committee’s decisions shall be final, binding, and conclusive on the Participant and the Participant’s successors, assigns and representatives in respect of any questions arising under this Agreement, the Grant Notice, or the Plan. In the event of any conflict between the Plan and this Agreement or the Plan and the Grant Notice, the Plan shall control. In the event of any conflict between this Agreement and the Grant Notice, this Agreement shall control.

3.Vesting. Subject to the Participant’s continued employment with the Company or an Affiliate (except as otherwise provided below or in the Plan), the RSUs shall vest in accordance with the schedule set forth in the Grant Notice.

(a)Termination of Employment. Except as provided below, the Participant shall immediately forfeit all unvested RSUs, together with all corresponding Dividend Equivalents rights, upon the termination of the Participant’s employment for any reason prior to the applicable vesting date, with any vested RSUs that are unsettled or unpaid as of such termination date to be settled or paid, together with any corresponding Dividend Equivalents, on the date specified in Section 4.

(i)Retirement. If the Participant’s employment with the Company or an Affiliate terminates due to the Participant’s Retirement (as defined below) on

1

or after the first anniversary of the Grant Date but before the third anniversary of the Grant Date, then (1) if the Participant has attained age 60 as of the date of such Retirement, the unvested RSUs shall continue to vest and be settled or paid, together with any corresponding Dividend Equivalents, on the date specified in Section 4 as if such termination of employment had not occurred, and (2) if the Participant has not attained age 60 on or before the date of such Retirement, the unvested RSUs shall continue to vest until the first anniversary of the Grant Date to occur after the date of such Retirement and shall be settled or paid, together with any corresponding dividend equivalents, on the date specified in Section 4, with any RSUs that are not scheduled to vest until after such anniversary of the Grant Date to be forfeited with no compensation due therefor. If the Participant’s employment with the Company or an Affiliate terminates due to the Participant’s Retirement prior to the first anniversary of the Grant Date, then all RSUs granted hereunder shall remain unvested and shall be forfeited immediately with no compensation due therefor. For purposes of this Agreement, “Retirement” means the Participant’s voluntary termination of employment with six months’ prior written notice to the Company or applicable Affiliate on or after the later of (1) the date on which the Participant attains age 55, and (2) the date on which the Participant completes 5 full years of service with the Company or an Affiliate.

(ii)Termination due to Death or Disability. If the Participant’s employment with the Company or an Affiliate terminates prior to the third anniversary of the Grant Date due to the Participant’s death or disability (as defined in Section 409A of the Code or any successor provision), all unvested RSUs outstanding hereunder at such time shall immediately vest and, together with any corresponding Dividend Equivalents, shall be settled or paid to the Participant or the Participant’s beneficiary or estate, as applicable, within 30 days thereafter.

(b)Change in Control. Except as provided below, the RSUs shall remain outstanding and continue to vest in accordance with the terms and conditions of this Agreement and the Plan, including Section 11 thereof, following the occurrence of a Change in Control. Notwithstanding the foregoing, any RSUs vested pursuant to Section 11 of the Plan, together with any corresponding Dividend Equivalents, shall be settled or paid to the Participant within 30 days after vesting. In addition and notwithstanding the foregoing, if the Participant experiences a Qualifying Termination on or within two years following such Change in Control, all RSUs (or any shares, units, or other awards granted in substitution for the RSUs) outstanding on the date of such Qualifying Termination shall immediately vest and, together with any corresponding Dividend Equivalents, shall be settled or paid to the Participant within 30 days after vesting.

4.Payment and Timing.

(a)Settlement / Payment. As soon as is administratively practicable after the applicable vesting date, but no later than March 15 of the following calendar year, the

2

Company shall (i) issue to the Participant one Share in settlement of each vested RSU and (ii) pay the Participant any corresponding Dividend Equivalents accrued with respect to each vested RSU.

(b)Dividend Equivalents. Each RSU shall include the right to receive Dividend Equivalent payments upon settlement of the RSU. For each RSU that vests and becomes payable to the Participant under this Agreement, such Dividend Equivalent right shall entitle the Participant to payment of an amount equal to the dividends (other than special or extraordinary dividends or distributions, unless otherwise determined by the Committee) declared on one Share from the Grant Date until the settlement date of the corresponding RSU. Dividend Equivalent payments shall be made in cash unless otherwise determined by the Committee in its sole discretion. The Dividend Equivalent rights granted under this Agreement are subject to the same vesting and payment conditions as the RSUs. If an RSU is terminated, cancelled, or forfeited hereunder without settlement, the corresponding Dividend Equivalent right shall thereupon be terminated, cancelled, or forfeited without payment.

(c)Withholding. All amounts payable under this Agreement, whether in cash or in Shares, are subject to withholding of all applicable taxes, and, except as otherwise provided by the Committee, the delivery of any Shares or other payments or benefits under this Agreement are conditioned on the Participant’s satisfaction of the applicable withholding requirements. The Company will withhold from the distribution of any cash pursuant to this Agreement the amount it determines in its sole discretion to be necessary to satisfy its federal, state, and local and employment tax withholding requirements. Unless otherwise elected by the Participant in accordance with procedures established by the Committee, the Company shall withhold from the Shares otherwise issuable to the Participant upon the settlement of the vested RSUs such number of Shares having a Fair Market Value equal to the amount required to be withheld by the Company, as determined in its sole discretion. All elections shall be irrevocable, made in writing, and signed by the Participant, and shall be subject to any restrictions or limitations that the Committee, in its sole discretion, deems appropriate.

(d)Restrictions. None of the RSUs, Dividend Equivalents or any other right granted under this Agreement may be pledged, attached, or otherwise encumbered other than in favor of the Company, and any purported pledge, attachment, or encumbrance thereof other than in favor of the Company shall be void and unenforceable against the Company or any Affiliate. Notwithstanding the foregoing, the RSUs, Dividend Equivalents, and all other rights granted hereunder shall be assignable or transferable (i) by will or the laws of descent and distribution; or (ii) with the consent of the Committee, by a gift or domestic relations order to any Family Member, to a trust in which the Participant and/or his or her Family Members hold more than 50% of the beneficial interest, to a foundation in which the Participant and/or Family Members control the management of assets, and any other entity in which the Participant and/or his or her Family Members own more than 50% of the voting interests.

3

(e)Rights as a Shareholder. The Participant shall have no rights as a shareholder of the Company with respect to any Share under this Agreement unless and until such Share is delivered to the Participant in settlement of a vested RSU.

(f)General Restrictions. Delivery of Shares or other amounts under this Agreement shall be subject to the following:

(i)Notwithstanding any other provision of this Agreement or the Plan to the contrary, the Company shall have no liability to deliver any Shares under this Agreement or make any other distribution of benefits under this Agreement 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.

(ii)To the extent that this Agreement or the Plan provide for issuance of stock certificates to reflect the issuance of Shares, such issuance may be made on a non-certificated basis, to the extent not prohibited by applicable law or the applicable rules of any stock exchange.

5.Miscellaneous.

(a)Acknowledgments of Participant. By executing the Grant Notice, the Participant acknowledges and agrees that: (i) the Participant shall, during employment, devote his or her entire time, energy and skill to the service of the Company 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, the Company and its Affiliates; and (ii) the Award is special compensation, and any amount paid hereunder will not affect: (1) the amount of any pension under any pension or retirement plan in which the Participant participates as an employee of the Company; (2) the amount of coverage under any group life insurance plan in which the Participant participates as an employee of the Company, or (3) the benefits under any other benefit plan of any kind heretofore or hereafter in effect, under which the availability or amount of benefits is related to compensation, in each case unless required pursuant to the terms of such plan.

(b)No Fractional Shares. No fractional Shares shall be issued or delivered pursuant to this Agreement, 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.

(c)No Trust or Fund Created. The Company’s obligations under this Agreement shall, at all times, be unfunded. This Agreement shall not create or be deemed to create: (i) a trust or separate fund of any kind; (ii) an interest on the part of the Participant or any other Person in any asset of the Company or any Affiliate; or (iii) a fiduciary relationship between the Company or any Affiliate and the Participant or any

4

other Person. To the extent that the Participant or any other Person acquires a right to receive payments from the Company or any Affiliate pursuant to this Agreement, such right shall be no greater than the right of any unsecured general creditor of the Company or any Affiliate.

(d)Company Policies. The RSUs and this Agreement shall be subject to any “clawback,” compensation recoupment, or other similar policy of the Company applicable to such Award, regardless of when such policy is adopted.

(e)Notices. All notices, demands and other communications provided for or permitted hereunder shall be in writing and delivered in person or sent by registered or certified first-class mail, return receipt requested, telecopier, or courier service:

if to the Company:

Olin Corporation

190 Carondelet Plaza

Suite 1530

Clayton, MO 63105

Attention: Chief Legal Officer

if to the Participant, at the Participant’s last known address on file with the Company.

All such notices, demands and other communications shall be deemed to have been duly given when delivered by hand, if personally delivered; when delivered by courier, if delivered by commercial courier service; five business days after being deposited in the mail, postage prepaid, if mailed; and when receipt is mechanically acknowledged, if telecopied.

6.Severability. If any provision of this Agreement is determined to be invalid, illegal or unenforceable, 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 this Agreement, such provision shall be stricken, and the remainder of this Agreement shall remain in full force and effect.

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

8.Beneficiary. The Participant may, in the manner established by the Committee and pursuant to the terms of Section 13(e) of the Plan, designate a beneficiary or beneficiaries with respect to this Agreement to exercise the rights of the Participant and to receive any property distributable upon the death of the Participant. All rights under this Agreement shall be

5

exercisable, during the Participant’s lifetime, only by the Participant or a permitted transferee, or, if permissible under applicable law, by the Participant’s guardian or legal representative.

9.Successors. This Agreement shall be binding upon and inure to the benefit of the Company and its successors and assigns, and to the Participant and the Participant’s beneficiaries, executors, administrators, heirs, and successors.

10.Entire Agreement. This Agreement and the Plan contain the entire agreement and understanding of the parties with respect to the subject matter contained herein and supersede all prior communications, representations, and negotiations in respect thereto. No change, modification, or waiver of any provision of this Agreement shall be valid unless the same is in writing and signed by the parties hereto.

11.Governing Law. The validity, construction, and effect of this Agreement shall be determined in accordance with the laws of the State of Missouri, excluding any conflicts or choice of law rule or principle that might otherwise refer construction or interpretation of this Agreement to the substantive law of another jurisdiction. Any legal action against the Plan, Olin, an Affiliate, or the Committee may only be brought in the Circuit Court in St. Louis County and/or the United States District Court in St. Louis, Missouri.

12.Waiver. Any failure of the Company to enforce at any time any provision of this Agreement shall not be deemed to be a waiver of such provision or any other provision of this Agreement.

13.Headings. The headings of the Sections hereof are for convenience only, are not a part of this Agreement, and shall not serve as a basis for interpreting or construing this Agreement.

14.Signature in Counterparts. The Grant Notice may be signed in multiple counterparts, each of which shall be an original, with the same effect as if the signatures thereto were upon the same instrument.

15.Section 409A of the Code. This Agreement and all amounts payable hereunder are intended to be exempt from, or comply with, the requirements of Section 409A of the Code, and it shall be interpreted accordingly. Nevertheless, the tax treatment of any Award is not guaranteed, and none of the Company, its Affiliates, or their respective officers, directors, employees, consultants, agents, representatives or advisors shall be liable to the Participant or any other Person if any portion of this Agreement or any amount payable hereunder is subject to additional taxes, penalties, or interest under Section 409A of the Code or otherwise.

(a)Notwithstanding anything herein to the contrary, to the extent that any Award would constitute non-exempt “deferred compensation” for purposes of Section 409A of the Code and would be payable or distributable under this Agreement by reason of a Change in Control, or the Participant’s separation from service, such amount or benefit will not be payable or distributable to the Participant by reason of such

6

circumstance unless the circumstances giving rise to such Change in Control or separation from service meet any description or definition of “change in control event” or “separation from service”, as the case may be, in Section 409A of the Code and applicable regulations (without giving effect to any elective provisions that may be available under such definition). This provision does not prohibit the vesting of any Award upon a change of control or separation from service, however defined. If this provision prevents the payment or distribution of any Award, such payment shall be made on the date that would have applied absent such designated event or circumstance.

(b)Notwithstanding anything herein to the contrary, if an amount payable under this Agreement constitutes non-exempt “deferred compensation” for purposes of Section 409A of the Code and would otherwise be payable by reason of a Participant’s separation from service during a period in which the Participant is a Specified Employee (as defined below), then, subject to any permissible acceleration of payment by the Committee under Treas. Reg. Section 1.409A-3(j)(4)(ii) (domestic relations order), (j)(4)(iii) (conflicts of interest), or (j)(4)(vi) (payment of employment taxes): (i) the amount of such non-exempt deferred compensation that would otherwise be payable during the six-month period immediately following the Participant’s separation from service will be accumulated through and paid or provided on the first day of the seventh month following the Participant’s separation from service (or, if the Participant dies during such period, within 30 days after the Participant’s death) (in either case, the “Required Delay Period”); and (ii) the normal payment or distribution schedule for any remaining payments or distributions will resume at the end of the Required Delay Period. For purposes hereof, the term “Specified Employee” has the meaning given such term in Code Section 409A and the final regulations thereunder, provided, however, that, as permitted in such final regulations, the Company’s Specified Employees and its application of the six-month delay rule of Code Section 409A(a)(2)(B)(i) shall be determined in accordance with rules adopted by the Committee, which shall be applied consistently with respect to all nonqualified deferred compensation arrangements of the Company, including this Agreement and the Plan.

PERFORMANCE SHARE AWARD AGREEMENT

This Performance Share Award Agreement (this “Agreement”) is made by and between the Company and the Participant specified in the accompanying Grant Notice, effective as of the Grant Date set forth therein. References herein to this Agreement shall be deemed to include the Grant Notice unless the context clearly requires otherwise.

In consideration of the premises and covenants contained herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto, for themselves, their successors and assigns, hereby agree as follows:

1.    Grant of Performance Shares. Effective as of the Grant Date, the Company shall grant the Participant the target number of Performance Shares set forth in the Grant Notice. Each Performance Share shall represent the right to receive, upon settlement or payment, one Share or an amount in cash or other property having a Fair Market Value equal to one Share as of the applicable determination date, in accordance with the terms and conditions of this Agreement and the Plan. For each Performance Share granted hereunder, the Participant shall also receive a corresponding Dividend Equivalent right, subject to the terms and conditions of Section 4(b).

2.    Incorporation by Reference, Etc. The provisions of the Grant Notice and the Plan are incorporated herein by reference. Any capitalized term not otherwise defined in this Agreement shall have the definition set forth in the Grant Notice or the Plan, as applicable. The Committee shall have final authority to interpret and construe this Agreement, the Grant Notice, and the Plan and to make all determinations hereunder or thereunder, and the Committee’s decisions shall be final, binding, and conclusive on the Participant and the Participant’s successors, assigns and representatives in respect of any questions arising under this Agreement, the Grant Notice, or the Plan. In the event of any conflict between the Plan and this Agreement or the Plan and the Grant Notice, the Plan shall control. In the event of any conflict between this Agreement and the Grant Notice, this Agreement shall control.

3.    Vesting. Subject to the Participant’s continued employment with the Company or an Affiliate (except as otherwise provided below or in the Plan), the Performance Shares shall be eligible to vest as provided in the Grant Notice.

(a)    Termination of Employment. Except as provided below, the Participant shall immediately forfeit all unvested Performance Shares upon the termination of the Participant’s employment for any reason prior to the end of the Performance Cycle.

(i)    Termination without Cause or due to Disability or Retirement; Voluntary Resignation with Consent. If the Participant’s employment with the Company or an Affiliate terminates before the end of the Performance Cycle for any of the following reasons: (i) termination by the Company or Affiliate without cause or due to the Participant’s disability (as

1

defined in Section 409A of the Code or any successor provision), (ii) Retirement (as defined below); or (iii) voluntary resignation with the consent of the Company or an Affiliate, then the Participant shall vest in a pro-rata portion of the Performance Shares subject to this Agreement in an amount equal to the product of (1) the number of Performance Shares that, but for such termination of employment, the Participant would have become vested in at the end of the Performance Cycle multiplied by (2) a fraction with a numerator equal to the number of months during the Performance Cycle the Participant was employed by the Company or an Affiliate (rounded up to the nearest whole month) and a denominator of 36. Such pro-rata portion of the Performance Shares, together with any corresponding Dividend Equivalents, shall be paid to the Participant following the end of the Performance Cycle at the time specified in Section 4; provided, however, that, unless otherwise determined by the Committee in its sole discretion, such pro-rata award shall be paid to the Participant solely in cash. For purposes of this Agreement, “Retirement” means the Participant’s voluntary termination of employment on or after the later of (1) the date on which the Participant attains age 55, and (2) the date on which the Participant completes 5 full years of service with the Company or an Affiliate.

(ii)    Termination due to Death. If the Participant’s employment with the Company or an Affiliate terminates due to the Participant’s death before the end of the Performance Cycle, the Participant shall vest in a pro-rata portion of the Performance Shares granted under this Agreement (as determined below), and such vested Performance Shares, together with any corresponding Dividend Equivalents, shall be paid to the Participant’s beneficiary or estate, as applicable, in cash or, in the Committee’s sole discretion, in Shares or a combination of cash and Shares, within ninety (90) days following the Participant’s death. The number of Performance Shares that shall vest upon the Participant’s death shall equal (1) the number of Target Performance Shares multiplied by (2) a fraction with a numerator equal to the number of months during the Performance Cycle the Participant was employed by the Company or an Affiliate (rounded up to the nearest whole month) and a denominator of 36.

(iii)    Other Terminations. If the Participant’s employment with the Company or an Affiliate terminates for any other reason, the Company shall determine the portion, if any, of the Performance Shares that shall vest, and the form of payment (cash or shares or a combination thereof) that the Participant shall receive. That determination shall be made by the Committee in the case of any officer, and by the Chairman of the Board or the President, Chief Executive Officer, in the case of any non-officer employee; provided that if the Participant’s employment is terminated by the Company or an Affiliate for cause before the end of the Performance Cycle, the Participant shall immediately forfeit all unvested Performance Shares.

(b)    Change in Control. Except as provided below, the Performance Shares shall remain outstanding and continue to vest in accordance with the terms and conditions of this Agreement and the Plan, following the occurrence of a Change in Control. Notwithstanding the foregoing any Performance Shares vested pursuant to the Plan shall become vested and deemed earned or satisfied at target levels, notwithstanding that the applicable Performance Cycle shall not have been completed or the performance goals met, and such Performance Shares and any corresponding Dividend Equivalents shall be paid to the Participant in cash or as otherwise provided in this Agreement within 30 days following such Change in Control. In addition to and

2

notwithstanding the foregoing, if the Participant experiences a Qualifying Termination on or within two years following such Change in Control, all Performance Shares (or other shares, units, or awards granted in substitution for the Performance Shares) outstanding on the date of such Qualifying Termination shall become vested at target levels, notwithstanding that the applicable Performance Cycle shall not have been completed or the performance goals met, and such Performance Shares (or other shares, units, or awards granted in substitution for the Performance Shares), and any corresponding Dividend Equivalents, shall be paid in cash or as otherwise provided in this Agreement (or the substitute award agreement) within 30 days following such Qualifying Termination.

4.    Payment and Timing.

(a)    Settlement / Payment. As soon as is administratively practicable after the Committee determines the number of Performance Shares that have vested and are payable under this Agreement (the “Vested Share Number”), prior to the end of the calendar year following the conclusion of the Performance Cycle, the Company will (i) issue to the Participant a number of Shares equal to one-half of the Vested Share Number, rounded down to the nearest whole Share if such number is not a whole number; (ii) pay the Participant an amount in cash equal to the product of (1) the Fair Market Value of one Share on the last day of the Performance Cycle multiplied by (2) one-half of the Vested Share Number, rounded up to the nearest whole share if such number is not a whole number; and (iii) pay the Participant any corresponding Dividend Equivalents accrued with respect to each vested Performance Share.

(b)    Dividend Equivalents. Each Performance Share shall include the right to receive Dividend Equivalent payments upon settlement or payment of the Performance Share. For each Performance Share that vests and becomes payable to the Participant under this Agreement, such Dividend Equivalent right shall entitle the Participant to payment of an amount equal to the dividends (other than special or extraordinary dividends or distributions, unless otherwise determined by the Committee) declared on one Share from the Grant Date until the settlement or payment date of the corresponding Performance Share. Dividend Equivalent payments shall be made in cash unless otherwise determined by the Committee in its sole discretion. The Dividend Equivalent rights granted under this Agreement are subject to the same vesting and payment conditions as the Performance Shares. If a Performance Share is terminated, cancelled, or forfeited hereunder without settlement or payment, the corresponding Dividend Equivalent right shall thereupon be terminated, cancelled, or forfeited without payment.

(c)    Withholding. All amounts payable under this Agreement, whether in cash or in Shares, are subject to withholding of all applicable taxes, and, except as otherwise provided by the Committee, the delivery of any Shares or other payments or benefits under this Agreement are conditioned on the Participant’s satisfaction of the applicable withholding requirements. The Company will withhold from the distribution of any cash pursuant to this Agreement the amount it determines in its sole discretion to be necessary to satisfy its federal, state, and local and employment tax withholding requirements, including, without limitation, with respect to any portion of the Performance Shares settled in Shares.

3

(d)    Restrictions. None of the Performance Shares, Dividend Equivalents, or any other right granted under this Agreement may be pledged, attached, or otherwise encumbered other than in favor of the Company, and any purported pledge, attachment, or encumbrance thereof other than in favor of the Company shall be void and unenforceable against the Company or any Affiliate. Notwithstanding the foregoing, the Performance Shares, Dividend Equivalents, and all other rights granted hereunder shall be assignable or transferable (i) by will or the laws of descent and distribution; or (ii) with the consent of the Committee, by a gift or domestic relations order to any Family Member, to a trust in which the Participant and/or his or her Family Members hold more than 50% of the beneficial interest, to a foundation in which the Participant and/or Family Members control the management of assets, and any other entity in which the Participant and/or his or her Family Members own more than 50% of the voting interests.

(e)    Rights as a Shareholder. The Participant shall have no rights as a shareholder of the Company with respect to any Share under this Agreement unless and until such Share is delivered to the Participant in settlement of a vested Performance Share.

(f)    General Restrictions. Delivery of Shares or other amounts under this Agreement shall be subject to the following:

(i)    Notwithstanding any other provision of this Agreement or the Plan to the contrary, the Company shall have no liability to deliver any Shares under this Agreement or make any other distribution of benefits under this Agreement 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.

(ii)    To the extent that this Agreement or the Plan provide for issuance of stock certificates to reflect the issuance of Shares, such issuance may be made on a non-certificated basis, to the extent not prohibited by applicable law or the applicable rules of any stock exchange.

5

7.    No Right to Employment. This Agreement shall not be construed as giving the Participant the right to be retained in the employ of the Company or any Affiliate.

11.    Governing Law. The validity, construction, and effect of this Agreement shall be determined in accordance with the laws of the State of Missouri, excluding any conflicts or choice of law rule or principle that might otherwise refer construction or interpretation of this Agreement to the substantive law of another jurisdiction.

14.    Signature in Counterparts. The Grant Notice may be signed in multiple counterparts, each of which shall be an original, with the same effect as if the signatures thereto were upon the same instrument.

15.    Section 409A of the Code. This Agreement and all amounts payable hereunder are intended to be exempt from, or comply with, the requirements of Section 409A of the Code, and it shall be interpreted accordingly. Nevertheless, the tax treatment of any Award is not guaranteed, and none of the Company, its Affiliates, or their respective officers, directors,

6

employees, consultants, agents, representatives or advisors shall be liable to the Participant or any other Person if any portion of this Agreement or any amount payable hereunder is subject to additional taxes, penalties, or interest under Section 409A of the Code or otherwise.

(a)    Notwithstanding anything herein to the contrary, to the extent that any Award would constitute non-exempt “deferred compensation” for purposes of Section 409A of the Code and would be payable or distributable under this Agreement by reason of a Change in Control, or the Participant’s separation from service, such amount or benefit will not be payable or distributable to the Participant by reason of such circumstance unless the circumstances giving rise to such Change in Control or separation from service meet any description or definition of “change in control event” or “separation from service”, as the case may be, in Section 409A of the Code and applicable regulations (without giving effect to any elective provisions that may be available under such definition). This provision does not prohibit the vesting of any Award upon a change of control or separation from service, however defined. If this provision prevents the payment or distribution of any Award, such payment shall be made on the date that would have applied absent such designated event or circumstance.

(b)    Notwithstanding anything herein to the contrary, if an amount payable under this Agreement constitutes non-exempt “deferred compensation” for purposes of Section 409A of the Code and would otherwise be payable by reason of a Participant’s separation from service during a period in which the Participant is a Specified Employee (as defined below), then, subject to any permissible acceleration of payment by the Committee under Treas. Reg. Section 1.409A-3(j)(4)(ii) (domestic relations order), (j)(4)(iii) (conflicts of interest), or (j)(4)(vi) (payment of employment taxes): (i) the amount of such non-exempt deferred compensation that would otherwise be payable during the six-month period immediately following the Participant’s separation from service will be accumulated through and paid or provided on the first day of the seventh month following the Participant’s separation from service (or, if the Participant dies during such period, within 30 days after the Participant’s death) (in either case, the “Required Delay Period”); and (ii) the normal payment or distribution schedule for any remaining payments or distributions will resume at the end of the Required Delay Period. For purposes hereof, the term “Specified Employee” has the meaning given such term in Code Section 409A and the final regulations thereunder, provided, however, that, as permitted in such final regulations, the Company’s Specified Employees and its application of the six-month delay rule of Code Section 409A(a)(2)(B)(i) shall be determined in accordance with rules adopted by the Committee, which shall be applied consistently with respect to all nonqualified deferred compensation arrangements of the Company, including this Agreement and the Plan.

“Common Stock” means the common stock of Olin, par value $1.00 per share. “Final Share Number” has the meaning specified in Section 3 of this Program.

“LTIP” means the Olin Corporation 2026 Long Term Incentive Plan and any successor plan.

“Olin” or the “Company” means Olin Corporation.

“Performance Cycle” means, with respect to a Performance Share Award, a period of three calendar years, beginning with the calendar year in which such Performance Share Award is granted.

“Performance Share Award” means grants of “Performance Shares.”

“Performance Share” means a unit granted under the LTIP and this Program, maintained on the books of the Company during the Performance Cycle, denominated as one phantom share of Common Stock, and paid in cash or Common Stock in accordance with this Program.

“Program” means this Performance Share Program.

Capitalized terms not otherwise defined in this Program shall have the meaning specified in the LTIP.

Performance Objective

For each fiscal year (“Covered Year”) during the 3-year Performance Cycle, a performance objective (“Performance Objective”) based on Adjusted EBITDA (“Adjusted EBITDA”) shall be established by the Compensation Committee. For each Covered Year, the applicable

8

Performance Objective shall have a threshold, target, and maximum performance level with a corresponding percentage payout of target number of PSUs (“Payout Percentage”).

Each Covered Year Performance Objective and Payout Percentage will be determined by the Compensation Committee and provided at the time of the grant.

The Performance Shares are eligible to vest based on the level of achievement of the Adjusted EBITDA Goals for each Covered Year.

The number of Performance Shares awarded to each Participant for each Adjusted EBITDA Goal shall be adjusted based upon a comparison of Olin’s actual Adjusted EBITDA with that Adjusted EBITDA Goal, in accordance with the following chart:

Performance Level Adjusted EBITDA Achieved* Payout Percentage

Minimum 50% of Performance Objective to be determined annually by the Compensation Committee 50%

Target 100% of Performance Objective to be determined annually by the Compensation Committee 100%

Maximum At or above 125% of Performance Objective to be determined annually by the Compensation Committee 200%

* Percentages are subject to change based on Compensation Committee discretion

Straight line interpolation shall be used to determine the applicable Payout Percentage between the threshold and target performance levels and between the target and maximum performance levels.

Modification Based on TSR for the Performance Cycle

The total number of PSUs earned, if any, based on the Performance Objective as set forth above shall then be subject to adjustment, determined by multiplying such total number of PSUs by the TSR Multiplier Percentage determined based on the Company’s Total Shareholder Return (“TSR”) over the three-year Performance Cycle relative to the Performance Share Comparison Group, as set forth in the chart below:

Relative TSR Performance Percentile Rank TSR Multiplier Percentage

Below 20th Percentile

80%

20th – 80th Percentile

100%

Above 80th Percentile

120%

If financial performance for each Covered Year equals 200% of target, final award is multiplied by 120% with max payout of 240%.

9

“TSR” means, for the Company and each of the Peer Companies, the company’s total shareholder return, expressed as a percentage, which will be calculated by dividing (i) the Closing Average Share Value by (ii) the Opening Average Share Value and subtracting one from the quotient. The Closing Average Share Value shall mean the average dividend-adjusted closing price over the 20 trading days ending on December 31, 2028. The Opening Average Share Value shall mean the average dividend-adjusted closing price over the 20 trading days ending on December 31, 2025.

Relative TSR Performance Percentile means the Company’s TSR relative to the Total Shareholder Return of the Performance Share Comparison Group expressed as a percentile rank. Percentile rank shall be calculated with the Microsoft Excel formula PERCENTRANK, exclusive of the Company from the Peer Companies. The percentile rank of the Company shall be rounded down to the nearest one hundredth of one percent (0.01%).

“Performance Share Comparison Group” means Huntsman Corporation plus the constituent companies comprising the Standard & Poor’s 1500 Materials Index as of the first trading day of the Opening Average Share Value.

Adjustments to Performance Share Comparison Group. The Performance Share Comparison Group may, in the Committee’s discretion, be adjusted as follows: (a) in the event of a merger, acquisition, or business combination transaction of a member of the Performance Share Comparison Group (a “Peer Company”) with or by another Peer Company, the surviving entity shall remain a Peer Company, (b) in the event of a merger of a Peer Company with an entity that is not a Peer Company, or the acquisition or business combination transaction by or with a Peer Company, or with an entity that is not a Peer Company, in each case where the Peer Company is the surviving entity and remains publicly traded, the surviving entity shall remain a Peer Company, (c) in the event of a merger or acquisition or business combination transaction of a Peer Company by or with an entity that is not a Peer Company or a “going private” transaction involving a Peer Company where the Peer Company is not the surviving entity or is otherwise no longer publicly traded as of the last trading day of the Performance Cycle, the company shall no longer be a Peer Company (for the avoidance of doubt, if a Share Value is calculable for a Peer Company on the last trading day of the Performance Cycle, that Peer Company shall remain a Peer Company), (d) in the event of a bankruptcy, liquidation or delisting of a Peer Company, such company shall remain a Peer Company but the TSR for such Peer Company shall be assumed to be a negative 100%, and (e) in the event of a stock distribution from a Peer Company consisting of the shares of a new publicly-traded company (a “spin-off”), the Peer Company shall remain a Peer Company and the stock distribution shall be treated as a dividend from the Peer Company based on a value as determined by a reputable data provider (e.g., S&P Global, Bloomberg, or Factset) and the performance of the shares of the spun-off company shall not thereafter be tracked for purposes of calculating TSR. Each Peer Company’s “common stock” shall mean that series of common stock that is publicly traded on a registered U.S. exchange or, in the case of a non-U.S. company, an equivalent non-U.S. exchange. For purposes of calculating TSR, the value on any given trading day of any Peer Company shares traded on a foreign exchange will be converted to U.S. dollars.

References herein to this Agreement shall be deemed to include the Grant Notice unless the context clearly requires otherwise.

In consideration of the premises and covenants contained herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto, for themselves, their successors and assigns, hereby agree as follows:

(a)Right to Exercise.

(i)This Option may not be exercised for a fraction of a Share and may not be exercised as to less than twenty-five (25) Shares at any one time.

In the event this Option is being exercised by a representative of the Participant, the notice shall be accompanied by proof (satisfactory to the Company) of the representative’s right to exercise this Option. The written notice shall be accompanied by payment of the aggregate Exercise Price for the purchased Shares in accordance with Section 4 below.

(ii)As a condition to the exercise of this Option and as further set forth in Section 7 of this Agreement, the Participant agrees to make adequate provision for federal, state or other applicable tax, withholding, required deductions or other payments, if any, which arise upon the grant, vesting or exercise of this Option, or disposition of Shares, whether by withholding, direct payment to the Company, or otherwise, as determined by the Company in its sole discretion.

(iii)The Company is not obligated, and will have no liability for failure, to issue or deliver any Shares upon exercise of this Option unless such issuance or delivery would comply with the applicable laws, with such compliance determined by the Company in consultation with its legal counsel. This Option may not be exercised if the issuance of such Shares upon such exercise or the method of payment of consideration for such Shares would constitute a violation of any applicable laws, including any applicable U.S. federal or state securities laws or any other law or regulation. As a condition to the exercise of this Option, the Company may require the Participant to make any representation and warranty to the Company as may be required by the applicable laws.

By executing the Grant Notice, the Participant acknowledges and agrees that: (i) the Participant shall, during employment, devote his or her entire time, energy and skill to the service of the Company 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, the Company and its Affiliates; and (ii) the Award is special compensation, and any amount paid hereunder will not affect: (1) the amount of any pension under any pension or retirement plan in which the Participant participates as an employee of the Company; (2) the amount of coverage under any group life insurance plan in which the Participant participates as an employee of the Company, or (3) the benefits under any other benefit plan of any kind heretofore or hereafter in effect, under which the availability or amount of benefits is related to compensation, in each case unless required pursuant to the terms of such plan.

All rights under this Agreement shall be exercisable, during the Participant’s lifetime, only by the Participant or a permitted transferee, or, if permissible under applicable law, by the Participant’s guardian or legal representative.

15.Successors. This Agreement shall be binding upon and inure to the benefit of the Company and its successors and assigns, and to the Participant and the Participant’s beneficiaries, executors, administrators, heirs, and successors.

16.Entire Agreement. This Agreement and the Plan contain the entire agreement and understanding of the parties with respect to the subject matter contained herein and supersede all prior communications, representations, and negotiations in respect thereto. No change, modification, or waiver of any provision of this Agreement shall be valid unless the same is in writing and signed by the parties hereto.

17.Governing Law. The validity, construction, and effect of this Agreement shall be determined in accordance with the laws of the State of Missouri, excluding any conflicts or choice of law rule or principle that might otherwise refer construction or interpretation of this Agreement to the substantive law of another jurisdiction. Any legal action against the Plan, Olin, an Affiliate, or the Committee may only be brought in the Circuit Court in St. Louis County and/or the United States District Court in St. Louis, Missouri.

18.Waiver. Any failure of the Company to enforce at any time any provision of this Agreement shall not be deemed to be a waiver of such provision or any other provision of this Agreement.

19.Headings. The headings of the Sections hereof are for convenience only, are not a part of this Agreement, and shall not serve as a basis for interpreting or construing this Agreement.

20.Signature in Counterparts. The Grant Notice may be signed in multiple counterparts, each of which shall be an original, with the same effect as if the signatures thereto were upon the same instrument.

21.Section 409A of the Code. This Agreement and all amounts payable hereunder are intended to be exempt from, or comply with, the requirements of Section 409A of the Code, and it shall be interpreted accordingly. Nevertheless, the tax treatment of any Award is not guaranteed, and none of the Company, its Affiliates, or their respective officers, directors, employees, consultants, agents, representatives or advisors shall be liable to the Participant or any other Person if any portion of this Agreement or any amount payable hereunder is subject to additional taxes, penalties, or interest under Section 409A of the Code or otherwise.

7

(a)Notwithstanding anything herein to the contrary, to the extent that any Award would constitute non-exempt “deferred compensation” for purposes of Section 409A of the Code and would be payable or distributable under this Agreement by reason of a Change in Control, or the Participant’s separation from service, such amount or benefit will not be payable or distributable to the Participant by reason of such circumstance unless the circumstances giving rise to such Change in Control or separation from service meet any description or definition of “change in control event” or “separation from service”, as the case may be, in Section 409A of the Code and applicable regulations (without giving effect to any elective provisions that may be available under such definition). This provision does not prohibit the vesting of any Award upon a change of control or separation from service, however defined. If this provision prevents the payment or distribution of any Award, such payment shall be made on the date that would have applied absent such designated event or circumstance.

(b)Notwithstanding anything herein to the contrary, if an amount payable under this Agreement constitutes non-exempt “deferred compensation” for purposes of Section 409A of the Code and would otherwise be payable by reason of a Participant’s separation from service during a period in which the Participant is a Specified Employee (as defined below), then, subject to any permissible acceleration of payment by the Committee under Treas. Reg. Section 1.409A-3(j)(4)(ii) (domestic relations order), (j)(4)(iii) (conflicts of interest), or (j)(4)(vi) (payment of employment taxes): (i) the amount of such non-exempt deferred compensation that would otherwise be payable during the six-month period immediately following the Participant’s separation from service will be accumulated through and paid or provided on the first day of the seventh month following the Participant’s separation from service (or, if the Participant dies during such period, within 30 days after the Participant’s death) (in either case, the “Required Delay Period”); and (ii) the normal payment or distribution schedule for any remaining payments or distributions will resume at the end of the Required Delay Period. For purposes hereof, the term “Specified Employee” has the meaning given such term in Code Section 409A and the final regulations thereunder, provided, however, that, as permitted in such final regulations, the Company’s Specified Employees and its application of the six-month delay rule of Code Section 409A(a)(2)(B)(i) shall be determined in accordance with rules adopted by the Committee, which shall be applied consistently with respect to all nonqualified deferred compensation arrangements of the Company, including this Agreement and the Plan.
