PROXY STATEMENT


____________________
ANNUAL MEETING OF SHAREHOLDERS

To be Held on April 26, 2018

IMPORTANT NOTICE REGARDING THE AVAILABILITY OF PROXY MATERIALS FOR THE ANNUAL MEETING OF SHAREHOLDERS TO BE HELD ON APRIL 26, 2018

Olin’s Notice of Annual Meeting of Shareholders and Proxy Statement and 2017 Annual Report onForm 10-K23, 2020   are available atwww.proxydocs.com/oln. You will need your11-digit control number located in the upper right box on the front of your proxy card or the notice regarding the availability of proxy materials to vote your shares.

GENERAL QUESTIONS

Why did I receive a notice in the mail regarding the availability of proxy materials instead of printed copies of the proxy materials?

In accordance with rules adopted by the U.S. Securities and Exchange Commission (SEC), we may furnish proxy materials to our shareholders by providing access to these documents on the Internet instead of mailing printed copies. Unless you are a participant in the Olin Corporation Contributing Employee Ownership Plan (the CEOP), you will not receive printed copies of the materials unless you request them. Instead, we mailed you the notice regarding the availability of proxy materials (unless you have previously consented to electronic delivery or already requested to receive printed copies), which describes how you may access and review all of the proxy materials on the Internet. The notice regarding the availability of proxy materials provides instructions as to how shareholders can access the proxy materials online, contains a listing of matters to be considered at the meeting, and sets forth instructions as to how shares can be voted. Shares must be voted either on the Internet, by telephone, or by completing and returning a proxy card. Shares cannot be voted by marking, writing on and/or returning the notice regarding the availability of proxy materials. Any notices regarding the availability of proxy materials that are returned will not be counted as votes. Instructions for requesting a paper copy of the proxy materials are set forth on the notice regarding the availability of proxy materials.

This process is designed to expedite shareholders’ receipt of proxy materials, lower the cost of the annual meeting, and help conserve natural resources. However, if you prefer to receive printed proxy materials via mail or receive an e-mail with links to the electronic materials, please follow the instructions included on the notice regarding the availability of proxy materials.

Why did I receive this proxy statement?

You received this proxy statement because you owned shares of Olin Corporation (Olin) common stock, par value $1 per share, which we sometimes refer to as common stock, at the close of business on February 28, 2018.2020. Olin’s board of directors is asking you to vote at the 20182020 annual meeting FOR each of the director nominees identified in Item 1 and FOR each of Items 2, 3 and 4 listed in the notice of the annual meeting of shareholders. This proxy statement describes the matters on which we would like you to vote and provides information so that you can make an informed decision.

When was this proxy material mailed to shareholders?

We began to mail the proxy statement and form of proxy to shareholders on or about March 12, 2018.

27, 2020.


When was the notice regarding the availability of proxy materials mailed to shareholders?

We began to mail the notice regarding the availability of proxy materials to shareholders on or about March 12, 2018.

What if I have questions?

If you have questions, please write them downcontact Olin’s proxy solicitor:
Innisfree M&A Incorporated
501 Madison Avenue, 20th Floor
New York, NY 10022
Shareholders call toll free 877-750-9496
Banks and send them to the Secretary at Olin’s principal executive office at 190 Carondelet Plaza, Suite 1530, Clayton, MO 63105 USA.

Brokers call 212-750-5833

Info@innisfreema.com
What will I be voting on?

You will be voting on:

1.

the election of the four directors identified in the proxy statement;

2.

the approval of the Olin Corporation 2018 Long Term Incentive Plan;

3.

an advisory vote to approve the compensation for named executive officers;

4.

the ratification of KPMG LLP (KPMG) as Olin’s independent registered public accounting firm for 2018; and

5.

any other business properly presented at the annual meeting.

1. the election of six directors;
2. an advisory vote to approve the compensation for named executive officers;
3. the ratification of the appointment of KPMG LLP (KPMG) as Olin’s independent registered public accounting firm for 2020;
4. a proposal of the board of directors to declassify the board of directors; and
5. any other business properly presented at the annual meeting.

The proposal to ratify the appointment of KPMG as Olin’s independent registered public accounting firm for 20182020 is considered a discretionary item for which a broker will have discretionary voting power if you do not give instructions with respect to this proposal. The proposals to elect directors, to approve the Olin Corporation 2018 Long Term Incentive Plan and to conduct an advisory vote to approve the compensation for named executive officers and to act on a proposal of the board of directors to declassify the board of directors arenon-routine matters for which a broker will not have discretionary voting power and for which specific instructions from beneficial owners are required. As a result, a broker will not be allowed to vote on these three matters on behalf of its beneficial owner customers if the customers do not return specific voting instructions. If you are a shareholder that holds shares through a broker, please provide specific voting instructions to your broker.


Proxy Statement Table of Contents
Could other matters be voted on at the annual meeting?

As of March 12, 2018,27, 2020, the items listed in the preceding question are the only matters being considered. If any other matters are properly presented for action, the persons named in the accompanying form of proxy will vote the proxy in accordance with their good faith business judgment as to what is in the best interests of Olin.

How does the board recommend I vote on the proposals?

Our board recommends a vote FOR each of the director nominees identified in Item 1 and FOR Items 2, 3 and 4.

What is a broker non-vote?
A broker non-vote occurs when brokers, banks or other nominees holding shares for a beneficial owner have discretionary authority to vote on “routine” matters brought before a shareholder meeting, but the beneficial owner of the shares fails to provide the broker, bank or other nominee with specific instructions on how to vote any “non-routine” matters brought to a vote at the shareholders meeting.
Brokers, banks and other nominees will be entitled to vote your shares on “routine” matters without instructions from you. The only proposal that would be considered “routine” in such event is the proposal for the ratification of the appointment of KPMG as Olin’s independent registered public accountants. A broker, bank or other nominee will not be entitled to vote your shares on any “non-routine” matters, absent instructions from you. “Non-routine” matters include the election of directors, the approval, on a non-binding advisory basis, of the compensation paid to Olin’s named executive officers and action on the board of directors’ proposal to declassify the board of directors.
Consequently, if you do not submit any voting instructions to your broker, bank or other nominee, your broker, bank or other nominee may exercise its discretion to vote your shares on the proposal to ratify the appointment of KPMG. If you do not direct your broker, bank or other nominee as to how your shares should be voted, your shares will constitute broker non-votes on each of the other proposals. Broker non-votes will count for purposes of determining whether a quorum exists, but will not be counted as votes cast with respect to such proposals.
What do I need to do to attend the 20182020 annual meeting in person?

Each attendee must bring a valid, government-issued photo ID, such as a driver’s license or passport, as well as other verification of Olin common stock ownership. For a shareholder of record or participant in the CEOP,Olin Corporation Contributing Employee Ownership Plan (CEOP), please bring your notice or the upper half of your proxy card (CEOP shares must be voted either on the Internetonline or by telephone no later than April 20, 2020 at 11:59 p.m. Central Daylight Time, on April 22, 2018, or by mail ifreceived by no later than April 20, 2018)18, 2020). If you are a beneficial owner of Olin common stock, but do not hold your

shares in your own name (i.e., your shares are held in street name), please bring the notice or voting instruction form you received from your bank, broker or other nominee. You may also bring your bank or brokerage account statement reflecting your ownership of Olin common stock as of February 28, 2018,2020, the record date.

If you hold your shares through a bank, broker or other nominee, you will not be permitted to vote at the meeting without obtaining a “legal proxy” from that nominee.

Please note that cameras, sound or video recording equipment, cellular telephones, smartphones and other similar devices, as well as purses, briefcases, backpacks and packages, will not be allowed in the meeting room. No one will be admitted to the meeting once it begins.

ITEM 1—PROPOSAL FOR THE ELECTION OF DIRECTORS

Who are the individuals nominated by the board to serve as directors?

The board of directors is currently divided into three classes.
Each class has a term of office for three years, and the term of each class ends in a different year. In 2017,Mr. Randall W. Larrimore, who is currently a Class II director with a term expiring at the 2020 annual meeting, is not standing for re-election and will be retiring from his position as a director at the 2020 annual meeting.

Virginia law and Olin’s Bylaws require that any director elected by the board of directors (rather than the shareholders) serve only until the earlier of the next election of directors by the shareholders (in this case, the 2020 annual meeting) and until his or her successor is elected or until his or her earlier death, resignation or removal. For this reason, each of Ms. Alderman, Ms. Babcock, Mr. Ferguson and Mr. Hauptfuhrer is required to be re-elected by shareholders at the 2020 annual meeting.
The board has nominated Ms. Beverley A. Babcock, Mr. BogusGray G. Benoist, Mr. John E. Fischer and Mr. Scott D. Ferguson as Class II directors with terms expiring in 2023, Ms. Heidi S.

Barnes Hauptfuhrer as a Class III directorsI director with a term expiring in 2022. However, the board is also recommending that Olin’s shareholders vote FOR Item 4 to approve an amendment to Olin’s articles of incorporation to declassify the board of directors. If such amendment is adopted by shareholders, all of the foregoing nominees will instead serve one-year terms expiring in 2021.
The board expects that all of the nominees recommended by it will be able to serve as directors. If any nominee is unable to accept election, a proxy voting in favor of such nominee will be voted for the election of a substitute nominee selected by the board, unless the board reduces the number of directors.

The board of directors recommends a vote FOR the election of Mr. Bogus as a Class II directorMses. Alderman and Ms. WilliamsBabcock and Messrs. ShippBenoist, Ferguson, Fischer and SmithHauptfuhrer as Class III directors.

How many votes are required to elect a director?

A majority of the votes cast means that the number of votes FOR a nominee must exceed the number of votes AGAINST that nominee.

What Is Olin’s Director Nomination Process?


Our directors and corporate governance committee acts as our nominating committee. As a policy, the committee considers any director candidates suggested by shareholders if we receive the appropriate information in a timely manner. Our Principles of Corporate Governance provide that the board chair, CEO, lead director, other directors, employees and shareholders may recommend director nominees to the committee. The committee uses the same process to review and evaluate all potential director nominees, regardless of who recommends the candidate. The committee reviews and evaluates each nominee and the committee chair, the board chair, CEO and lead director interview the potential new board candidates selected by the committee. The interview results, along with the committee’s recommended nominees, are submitted to the full board.

Our Principles of Corporate Governance describe criteria for new board members to includeincluding recognized achievement plus skills such as a special understanding or ability to contribute to some aspect of Olin’s business. The committee is tasked with seeking board members with the personal qualities and experience that taken together will ensure a strong board of directors. Although we have no formal policy on diversity for board members, ourOur Principles of Corporate Governance provide that racial, ethnic and gender diversity are important factors in assessing potential board members, in addition to particular qualifications and experience required to meet the needs of the board. Furthermore, as
As part of the committee’stheir review of board composition,nominations, the board considersand the committee consider diversity of experience and background in an effort to ensure that the composition of our directors ensures a strong and effective board. Our Principles of Corporate Governance cite strength of character, an inquiring and independent mind, practical wisdom and mature judgment as among the principal qualities of an effective director.

This year, we have foursix nominees standing for election orre-election.

re-election, including two women added to the board to fill vacancies in the past year.

A shareholder can suggest a person for nomination as a director by providing the name and address of the candidate, and a detailed description of his or her experience and other qualifications for the position, in writing addressed to the board of directors in care of the Secretary, Olin Corporation, 190 Carondelet Plaza, Suite 1530, Clayton, MO 63105 USA. The notice may be sent at any time, but for a candidate to be considered by the committee as a nominee for an annual meeting, we must

receive the written information at least 150 days before the anniversary of the date of the prior year’s proxy statement. For example, for candidates to be considered for nomination by the committee at the 20192021 annual meeting, we must receive the information from shareholders on or before October 12, 2018.

28, 2020.

In addition to shareholders proposing candidates for consideration by the committee, Olin’s Bylaws allow shareholders to directly nominate individuals at the annual meeting for election to the board by delivering a written notice as described under the heading “MISCELLANEOUS—How can I directly nominate a director for election to the board at the 20192021 annual meeting?” on page 7.6. Although a shareholder may directly nominate an individual for election as a director, the board is not required to include such nominee in the proxy statement.

What Is the Board Leadership Structure?


What Is the Board Leadership Structure?
Our Principles of Corporate Governance state that our board may select either a combined CEO board chair coupled with a lead director or appoint a board chair who does not also serve as CEO. Currently, Mr. Fischer serves as our combined CEO and chairman of the board, and the board selected Mr. RompalaWeideman as our independent lead director.

The board believes that this leadership structure is best for Olin at the current time, as it appropriately balances the need for the CEO to run the company on aday-to-day basis with significant involvement and authority vested in an outside independent board member—the lead director. Our lead director assumes many functions traditionally within the purview of a chairman of the board. Under our Principles of Corporate Governance, our lead director must be independent, and is responsible for:

How Does the Board Oversee Olin’s Risk Management Process?


Our board is responsible for oversight of Olin’s risk assessment and management process. The board delegated to the compensation committee basic responsibility for oversight of management’s

compensation risk assessment, and that committee reports to the board on its review. Our board also delegated tasks related to risk process oversight to our audit committee, which reports the results of its review process to the board. The audit committee’s process includes:

·

a review, at least annually, of our internal audit process, including the organizational structure and staff qualifications, as well as the scope and methodology of the internal audit process; and

·

a review, at least annually, of our enterprise risk management (ERM) program to ensure that an appropriate ERM process is in place, including discussion of the major risk exposures identified by Olin, the key strategic plan assumptions considered during the assessment and steps implemented to monitor and mitigate such exposures on an ongoing basis.

REPORT OF THE AUDIT COMMITTEE

The audit committee’s primary responsibility is to assist the board in its oversight of the integrity of the Corporation’sOlin’s financial reporting process and systems of internal control, to evaluate the independence and performance of the Corporation’sOlin’s independent registered public accounting firm, KPMG LLP (KPMG), and internal audit functions and to encourage private communication between the audit committee and KPMG and the internal auditors.

The committee held eightsix meetings during the year. During the second half of 2017,2019, the audit committee also completed a self-assessment.

In discharging its responsibility, the audit committee reviewed and discussed the audited financial statements for fiscal year 20172019 with management and KPMG, including the matters required to be discussed by the Public Company Accounting Oversight Board (PCAOB) Auditing Standard No.1301,Communications with Audit Committees.

.

In addition, the audit committee has received the written disclosures and the letter from KPMG required by applicable requirements of the PCAOB regarding KPMG’s communications with the audit committee concerning independence. The audit committee discussed with KPMG the issue of its independence from Olin and reviewed KPMG’s reports on the firm’s quality review procedures and findings, results of peer reviews and investigations and inquiries, including corrective actions taken. The audit committee also negotiated the hiring of KPMG for the 20172019 audit andpre-approved all fees which SEC rules require the committee to approve to ensure that the work performed was permissible under applicable standards and would not impair KPMG’s independence.

Based on the audit committee’s discussions with management and KPMG and the audit committee’s review of KPMG’s written report and the other materials discussed above, the audit committee recommended that the board of directors include the audited consolidated financial statements in Olin’s Annual Report on Form 10-K for the year ended December 31, 2017,2019, to be filed with the SEC.

disclosures. The committee viewed the results of this vote as general broad shareholder support for our executive compensation program. While we made no changes to our executive compensation program as a result of that vote, our committee continuously evaluates our executive compensation program and makes changes to respond to market trends and other relevant factors.

Pay for Performance


Pay for Performance
We understand that there are different ways to view “pay for performance.” In the following sections, we highlight how the committee thinks about executive pay and Olin performance, and why we believe our executive compensation programs are appropriately aligned with results that benefit our investors.

Compensation Program Construction

Our executive compensation program is designed to align with the long-term interests of our shareholders, to reward employees for producing sustainable growth, and to attract and retain the world-class talent that will ensure we succeed. The committee strongly believes that these objectives will be fulfilled if executive compensation—pay opportunities and pay actually realized—is tied to Olin’s results. The committee measures Olin performance in two primary ways for purposes of establishing executive compensation:

·

our financial results, particularly our Adjusted earnings before interest, taxes, depreciation and amortization (Adjusted EBITDA), adjusted cash flow and adjusted earnings per share (Adjusted EPS) (see pages 37-38), and

·

our return to shareholders over time relative to other companies.

our financial results, particularly our adjusted earnings before interest, taxes, depreciation and amortization (Adjusted EBITDA), Adjusted Cash Flow and adjusted earnings per share (Adjusted EPS) (see page 36), and

our relative total return to shareholders over time.
By tying our executives’ pay to Olin’s actual results, our compensation programs (i) align our executives’ interests with those of our shareholders and (ii) induce our management team to achieve our most important goals.

Our total direct compensation package comprises three elements:

·

base salary;

·

annual incentive (SMICP/MICP); and

·

long-term incentive (equity) compensation.

base salary;
annual cash incentive; and
long-term incentive (equity) compensation (LTI).
Each NEO has a target total compensation opportunity that is reviewed annually by the committee to ensure its alignment with Olin’spay-for-performance objectives. As the following chart shows, 84%86% of the target annual direct compensation of our current CEO and 72%74% of the target annual direct compensation for the other NEOs varies with our financial results and our stock price performance:

2019 Results

Olin delivered majorgenerated a number of operational accomplishments that informed the committee’s decision making as it related to executive compensation in 2017:

2019. Specifically, in 2019, we recorded our best full-year safety and environmental performance since the Dow acquisition in 2015. Total events, including safety, environmental, process safety and distribution, declined by 6.4%. Individual safety events declined by 5.2% and environmental events declined by 22%, and for the third consecutive year there were no life events. In a year where our businesses faced weaker demand and pressure on product pricing, we did achieve higher than expected productivity improvements. The Winchester business finished the year with two consecutive quarters of year-over-year increased Adjusted EBITDA, resulting in 2019 Adjusted EBITDA that exceeded 2018 results. In the third quarter of 2019, Winchester was awarded the contract by the U.S. Army to operate the Lake City Army Ammunition Plant effective October 1, 2020.

·

Generated improved EBITDA and EPS compared to 2016.

The Compensation Committee

·

Achieved higher than expected improvements in synergies and productivity.

·

Experienced a record year in safety in the Winchester division.

The Compensation Committee


The committee is the body primarily responsible for overseeing compensation to our senior officers. Our committee consists of directors who are independent under the NYSE listing criteria. The committee establishes total compensation opportunities (and each of the individual elements) for the CEO, and approves compensation for the other executive officers, including the NEOs, based on recommendations by the CEO.

To assist in performing its duties, the committee engages Exequity LLP (Exequity), an independent board and management advisory firm. In engaging Exequity, the committee considered a number of factors in assessing Exequity’s independence, including the factfacts that Exequity performs no other work for Olin, that none of Exequity’s consultants owns stock in Olin, that Exequity’s consultants have no other business interests with any Olin officer or director, and that the fees that Exequity receives for services rendered to Olin restare below a maximum permissible level. In the past several years, the committee discussed its compensation philosophy with Exequity, but otherwise did not impose any specific limitations or constraints on, or otherwise direct, the manner in which Exequity performed its advisory services.

Proxy Statement Table of Contents
As advisor to the committee, Exequity reviewed the total compensation strategy and pay levels for our NEOs, examined all aspects of our executive compensation programs to ensure their ongoing support of our business strategy, informed the committee of developing legal and regulatory considerations affecting executive compensation and benefit programs, and provided general advice to the committee on all compensation decisions pertaining to the CEO and to all senior executive compensation recommendations submitted by management. The committee routinely meets in executive session (without the CEO or other officers present). As appropriate, Exequity attends some of those executive sessions. In addition to the committee’s retention of Exequity, Olin periodically retains one or more other compensation consulting firms to provide general services, such as actuarial services for pension plans.

Benchmarking


Benchmarking
In designing and implementing our executive compensation programs, it has been the committee’s practice to review compensation data from a peer group that is adjusted periodically in consultation with Exequity. We refer to this group as the “comparator group.” For awards made in 2017,2019, the comparator group was composedcomprised a community of the 1920 chemical companies listed below,that align reasonably with medianOlin’s revenues, industry affiliation and corporate structure:

Air Products and Chemicals, Inc.PolyOne Corporation
Celanese CorporationPPG Industries, Inc.
CF Industries Holdings, Inc.Praxair, Inc.

Element Solutions, Inc. (formerly Platform Specialty Products Corporation)The Mosaic Company
FMC CorporationThe Scotts Miracle-Gro Company
H.B. Fuller CompanyThe Sherwin-Williams Company
Huntsman CorporationW. R. Grace & Co.
Ingevity CorporationWestlake Chemicals Corporation
The committee annually evaluates the comparator group composition and makes adjustments as appropriate. For 2020, Praxair, Inc. (which merged with The Linde Group) will be removed from the comparator group. Albemarle Corporation, Ashland Global Holdings Inc., Axalta Coating Systems Ltd., Cabot Corporation, and International Flavors & Fragrances Inc. will be added to the comparator group, as they are chemicals industry companies of $4.4 billion:

comparable revenue size to Olin. We believe these modifications will enhance the peer group’s representation of Olin’s revenue position, industry affiliation and corporate structure.

R. Grace & Co. were added to the 2017 comparator group. In future years, the committee intends to continue the practice of evaluating the comparator group and making adjustments as appropriate. For example, in 2018, DowDupont (the combination of The Dow Chemical Company and E.I. du Pont de Nemours and Company) will not be included in the comparator group due to its revenue size and The Valspar Corporation will not be included in the comparator group as it is no longer a separate reporting company, since its acquisition by The Sherwin-Williams Company.

What We Pay and Why: Elements of Compensation


We extend to our executives three elements of total direct compensation: base salary; annual incentive (SMICP/MICP);cash incentive; and long-term equity awards, plus a limited number of benefits that commonly are available to senior management at other companies of similar stature. The chart below illustrates that 81%75% of the 2017actual 2019 total direct compensation of our NEOs was tied to Olin performance.

Proxy Statement Table of Contents
The committee determines the total target direct compensation level for the CEO, as well as the appropriate mix of the compensation elements, based on prevailing practices in the comparator group. The CEO relies on comparator group standards to recommend, for the committee’s review and approval, the target levels and mix of elements for the balance of our executive officers. Although the committee is not bound to mirror the comparator group standards when it makes decisions on

compensation levels and the mix of elements, the committee generally relies heavily on the identified competitive norms to ensure that we can compete for executive talent. The committee also reviews the relationship between the CEO’s compensation and the compensation for the other NEOs. In connection with establishing 20172019 compensation, the committee determined that internal pay relationships were appropriate in light ofand reflected the committee’s understanding of the typical CEO-NEO pay relationships at other companies.

As a guideline, the committee intends that the base salaries, total cash compensation (salary and annual cash incentive), and total compensation opportunities (total cash compensation plus the grant date value of long-term incentive awards) extended to our NEOs as a group approximate the market median of the comparator group practices. The committee believes that managing total target pay to the market median for the comparator group allows us to attract, motivate, and retain the quality executive talent Olin needs. Pay levels for any individual NEO, however, may be below or above the market median of the comparator group for that executive’s particular role. The chart below shows how our 20172019 NEO compensation targetedapproximated the median compensation for the comparator group.

LOGO

NEO 2019 Target Compensation Against Market Median
neo2019trgtcompensationaga.jpg
Our general practice for an executive who is new in his/her position is to establish compensation opportunities below the market, and to increase them to market level over several years, assuming that performance warrants such increases. Other material increases in compensation generally relate to promotions or added responsibilities.

Salary

The committee normally adjusts NEO salaries annually in respect ofto reflect merit, promotion or change in role and changes in market rates for the job. No increase in base salary is automatic or guaranteed. When warranted by cash flow or other considerations, theThe frequency of adjustments, in fact, has been extended to 18 months or more when warranted by cash flow or other considerations, and on occasion we have frozen executive base salaries for extended periods of time.

For example, for 2020, we froze base salaries at 2019 levels for all NEOs (as well as for other officers and participants in our long-term incentive program).

Short Term Incentive Program (Non-equity Incentive Program Compensation)

Annual Cash Incentive(Non-equitySTIP Overview. For 2019, the committee adopted a new Short Term Incentive Plan Compensation)

For the past several years, including in 2017, the NEOs participated in the Senior Management Incentive Compensation Plan, or SMICP, an incentive plan approved by our shareholders. The SMICP provides the NEOs with annual cash incentive opportunities comparable to the terms and conditionsProgram (STIP) for cash bonus awards to our other executives (who participate in our Management Incentive Compensation Plan, or MICP). Use of the SMICP for these NEOs was intended to allow us to deduct payments to those individuals subject to the deduction limits of Section 162(m) of the Internal Revenue Code (Code), although the committee reserves the right to make payments that would not be deductible if it determines that doing so would be in our best interests.

The mechanics of the SMICP operation for 2017 awards were as follows:

Step 1:

Determine Comparator Group Metrics.The first step in the SMICP process was a determination of the maximum pool available to pay annual incentives to participating NEOs under the SMICP and to other executives under the MICP. The committee based this determination on the information provided by Exequity regarding the median percentage of net income allocated by the companies in the comparator group to fund annual incentives for their executives.

Step 2:

Determine Maximum SMICP Funding.The committee then considered and approved 6% of 2017 income to be set aside as a pool to fund annual cash incentives for both the SMICP and the MICP. For this purpose, income was calculated as 2017 Adjusted EPS multiplied by the weighted average number of shares outstanding in 2017, where Adjusted EPS represent consolidated net income from continuing operations before theafter-tax effect of special charges, gains or losses, or the cumulative effect of a change in accounting, divided by the weighted average number of shares outstanding on a fully diluted basis.

Step 3:

Determine Individual Amount for each NEO.The committee established a target award for each NEO (set forth in the Grants of Plan-Based Awards table). They allocated 30% of the formulated incentive pool to fund a maximum award for the CEO, 20% to fund maximum awards for each of the second and third highest paid NEOs and 30% to fund maximum awards for the other NEOs.

Step 4:

Establish Final Awards.The committee exercised its discretion after the end of 2017, to determine the award for each of the paid NEOs (not to exceed the maximum award for that NEO set forth in the Grants of Plan-Based Awards table), based on achievement of 2017 financial goals andnon-financial strategic objectives described below. For purposes of this analysis, financial objectives are weighted at 80% andnon-financial objectives are weighted at 20% for NEOs with corporate-wide responsibilities (75% and 25% weighting to financial and non-financial objectives, respectively, for NEOs with divisional responsibilities).

As discussed above, the committee established 6% of adjusted net income as the maximum pool for all awards under the SMICP and the MICP for 2017 performance. Our adjusted 2017 net income was $157.3 million, creating an aggregate pool for awards under the SMICP and the MICP of $9.4 million. Total actual payouts under both the SMICP and the MICP plans were $6.348 million, or 67.53% of the available pool. For 2017, in calculating Adjusted EPS used to determine adjusted 2017 net income, we excluded the effect of the following special charges, gains and losses (which were reflected in our 2017 net income): (i) restructuring charges of $32.5 million, (ii) $12.8 million of acquisition-related integration costs, (iii) $5.3 million of information technology costs, (iv) $54.7 million as a result of Hurricane Harvey, representing incremental costs to continue operations and unabsorbed fixed manufacturing costs, as well as reduced profits from lost sales, and (v) $3.3 million of gain on the sale of a former manufacturing facility.

The following table illustrates the portion of each NEO’s cash incentive based on corporate and division financial targets and corporate and divisionnon-financial objectives:

In 2017,addition, for each 1% by which the actual financial performance exceeds the financial targets (100%), the payout is increased by 4%. The total STIP payout for an NEO cannot exceed 200% of our NEOs with corporate-wide responsibilities (Messrs. Fischer, Slater and McIntosh),that individual’s target STIP award.
For 2019, 80% of his cash incentive isthe target STIP awards for all officers (including the NEOs) were based on financial targets and 20% of the target STIP awards were based onnon-financial objectives.

Financial Targets.In 2017, our The following table illustrates the portion of each NEO’s target STIP award based on corporate and division financial performance targets and non-financial objectives for 2019:

For Messrs. Dawson and Varilek, target STIP awards were based 25% on corporate results and 75% on division results. Of the 75% component related to division results, 20% (or 15% of the total target STIP award) related to division non-financial objectives and the remaining 80% (or 60% of the total target STIP award) was based on Adjusted Division EBITDA (50%), Adjusted Cash Flow (15%) and Adjusted EPS (15%Division Cash Flow. For Mr. Varilek, who had responsibility for both Chemicals businesses (Chlor Alkali Products and Vinyls (CAPV) and Epoxy) in 2019, his division Adjusted EBITDA financial targets and achievement against those targets were weighted equally between the CAPV and Epoxy divisions.

2018 Annual Cash Incentive Awards.The committee has determined that 80% of the 2018 annual cash incentive award will be tied to corporate financial objectives and 20% will be tied to

corporatenon-financial objectives for NEOs with corporate-wide responsibilities. For NEOs with divisional responsibilities, 75% of the award will be tied to financial objectives (split 75%/25% between division and corporate objectives) and 25% of the award will be tied to non-financial objectives (again split 75%/25% between division and corporate objectives). The committee also established the maximum cash incentive award for each NEO at 200% of his base salary, and established a maximum pool for all 2018 annual cash incentives for the NEOs and MICP participants at 6% of adjusted net income. Because of recent changes in the Code, performance-based awards are no longer exempt from the $1 million cap on compensation deductions for NEOs.

Long-Term Incentive (Equity) Compensation

In 2017,2019, we allocated the value of long-term incentive (equity) compensation awards equally between performance shares and stock options.

Why Stock Options?

Why Performance Shares?

· Performance-based because their value is solely tied to Olin’s stock price, which directly correlates to our shareholders’ interests.

· Fosters an environment focused on long-term growth and shareholder value creation.

· Declines in stock price following the grant of stock options detrimentally impact executive pay (i.e., when a stock option is “underwater” it has no value).

· Highly valued by employees; an important retention tool.

· Performance-based both because the number of shares earned depends on performance againstpre-defined financial goals and the value of the shares fluctuates based on the stock price.

· Motivates decision making that maximizes performance over a multi-year timeframe.

· Tied to key financial metrics—return on capital for 2015 and 2016 awards and both relative total shareholder return and net income for 2017 awards.income.

· Coordinates the activities of all award recipients (including our NEOs) in support of long-term organizational value enhancement.

These target awards are allocated equally between stock options and performance shares. The process the committee follows to determine the level of the actual stock option awards and the formula for actual performance share payouts is described below.

Performance Shares.Half the value of each participant’s 20172019 long-term incentive target award value was delivered in performance shares. The target number of performance shares awarded to each NEO was formulated by dividing half the participant’s target award value by the Black-Scholesfair market value of a performance share.our common stock (the average of the high and low per share sales price of our common stock on the NYSE on the grant date). The total number of performance shares that vest and will be paid to each NEO from awards made in 2017 varies2019 will vary between 0 and 200% of his target number.

For 2017 awards,

Half of the valuetarget number of half of all performance shares will be earned based on our relative shareholder return (TSR) over the three-year period ending December 31, 2019.2021. The comparison of our TSR over that period of time will be made relative to the community of companies in the S&P 1000 Material Index, plus threetwo selected direct competitors- competitors–Occidental Petroleum Corporation DowDupont and Westlake Chemical Corporation. We refer to this group of companies as the Performance Share Comparison Group. The remaining half of the target number of performance shares arewill be earned based on our actual net income performance compared to the net income goal set by the committee for the same three-year period.

Stock Options.The remaining half of each participant’s long-term incentive (equity) target award value is delivered in stock options. Stock options are granted annually from a committee-approved pool of option shares. Specifically, the pool of stock options available for issuance each year equals half the value of the overall long-term incentive award value, divided by the Black-Scholes value of options for our common stock (not to be lower than 20% of the then-current market price of our common stock).

We

The committee typically approveapproves option awards at the first committee meeting each year. In 2017,2019, the first committee meeting was January 26, 2017.24, 2019. At that meeting, the committee approved the granting of options effective on February 10, 2017, with an19, 2019. The exercise price of $29.75on February 19, 2019 was $26.26 per share, the average of the high and low per share sales price of our common stock on the NYSE on Februarythat date. These awards were made consistent with past practice in which the awards have:
a grant effective date approximately 10 2017. Whenbusiness days after the first scheduled meeting occurs before or nearrelease of year-end earnings; and
an exercise price equal to fair market value on the time we release ouryear-endgrant effective date. earnings report, the committee has granted stock options:

·

with a grant effective date approximately 10 days after the release ofyear-end earnings; and

·

with an exercise price equal to fair market value on the grant effective date.

This practice ensures that the exercise price for stock options reflects all current information. Although we have no formal policy on granting options at a time when inside information may exist, the committee follows the procedure we describe above when necessary to ensure that option exercise prices reflect full disclosure of prior year earnings information. We have not engaged in “back dating” of options, as our policies do not allow back dating. In addition, our equity plans do not permit option grants with an exercise price below the fair market value of our stock on the effective date of the option grant.

The CEO also has authority to grant a very limited number of options at other times during the year (no more than 50,000100,000 total shares or 5,000 shares per employee) but may not grant options to anyone who is an officer within the definition of the rules under Section 16 of the Exchange Act, or “back date” any options. Consistent with the terms of our equity plans, options granted by the CEO may not have an exercise price below the fair market value of our stock on the effective date of the option grant.

Restricted Stock.In April of 2019, the committee awarded 5,000 restricted stock units that vest on April 1, 2022, to Mr. Varilek in connection with his promotion to Executive Vice President and Chief Operating Officer. In addition, as noted above, the committee froze salaries at 2019 levels for NEOs and other senior employees. In lieu of a 2020 salary adjustment, the committee awarded restricted stock units on January 2, 2020, vesting on January 2, 2023, to those senior management employees affected by the salary freeze. For the NEOs, the number of shares of restricted stock issuable upon vesting of these restricted stock units represents approximately 3% of base salary, calculated based on the fair market value of our stock on the grant date, rounded to the nearest 10 shares. The committee does not award restricted stock or restricted stock units to NEOs on any regular basis.
Clawback Policy

As a participant in the SMICP, each

Each of our NEOs is subject to a clawback policy that applies to all of our executive officers. Amounts that we recover are not included in calculating that executive’s benefits under our Supplemental CEOP, and our recovery of amounts under the policy does not constitute an event that triggers benefits under our severance agreements.plans. In addition to the clawback policy, our equity plans provide that if a participant renders service to one of our competitors, or discloses confidential information without our consent, or violates other terms of the plan, the committee may terminate any unvested, unpaid or deferred awards held by the participant, or may require the participant to forfeit benefits received under the plan within the six months before the participant’s action.

Other Compensation

We also offer a small number of other personal benefits to groups of employees, including our NEOs. We extend some benefits, such as a portion of health insurance premiums and certain retirement benefits, to all eligible employees. We tie the size and construction of these benefits to competitive practices in the market, a decision the committee believes enables us to attract and retain executives with the talents and skill sets we require. We provide other compensatory items, such as certain life insurance benefits and the retirement and change in control benefits described below, to our NEOs and other senior managers.

officers.

Retirement Benefits.We offer retirement benefits as part of the package to recruit and retain employees. Our retirement benefits also reflect an individual’s contributions over his or her career with Olin, as those benefits are based on compensation. In general, we establish retirement benefits based on comparable programs offered by competitors. The committee believes that retirement plans like ours are commonly provided to executives at other companies, and offering these benefits helps us remain competitive for qualified senior-level executive talent. We periodicallyre-evaluate and update those plans to respond to changes in the market.

The following chart summarizes the benefits under our active retirement plans for salaried employees:

Plan Title


Participants/Purpose


Benefits


Olin Corporation Contributing
Employee Ownership Plan (the CEOP)—Employee Savings Account
Salaried employees—to provide employees with a tax effective savings vehicle to save primarily for retirementEligible employees may makepre-tax contributions (401(k)), Roth 401(k) contributions and after tax contributions. They may contribute up to 80% of eligible compensation (subject to various Code limits, including the 20172019 pre-tax and Roth 401(k) contribution limit of $18,000)$19,000). Olin generally matches a portion of base payeligible compensation that the participant contributes to the plan
CEOP—Defined Contribution Retirement AccountSalaried employees—to provide retirement benefits in lieu of benefits formerly provided under the Olin Corporation Employees’ Pension Plan (Qualified Plan) prior to benefit accrual freezeFor eligible employees, Olin makes contributions to the Defined Contribution Retirement Account ofbased on a percentage of eligible compensation
Supplemental CEOP—Employee Savings AccountSenior management (including former Dow employees effective 1/1/18)—management—to compensate for Code limits on CEOP contributionsEligible employees may makepre-tax contributions on eligible compensation in excess of Code limits and generally receive Olin matching contributions at the same percentages as the CEOP
Supplemental CEOP—Defined Contribution Retirement AccountSenior management (including former Dow employees effective 1/1/18)—management—to compensate for Code limits on CEOP contributionsOlin also makes contributions on eligible compensation in excess of Code limits at the same percentages as the CEOP Defined Contribution Retirement Account

The Supplemental CEOP is an unfunded, nonqualified deferred compensation plan for most of the NEOs and a select group of other senior management employees. Through 2017, former Dow employees (including Messrs. Dawson and Varilek) have slightly different terms for participation in the Supplemental CEOP to mirror their benefits while at Dow. The committee believes that historically it was common for companies to offer these kinds of nonqualified retirement supplements to executives and offering these benefits has allowed us to remain competitive in the market for qualified senior-level executive talent. Because this plan is unfunded, participants receive benefits only if we have the financial resources to make the payments when due.

Proxy Statement Table of Contents
Severance and Change in Control Plans.We have historically provided change in control benefits to our senior management to ensure that our executives worked to secure the best outcome for shareholders in the event of a possible change in control, even if it meant that they lost their jobs as a result. Those change in control and severance plans are described under “Potential Payments Upon Termination or Change in Control” and “Executive Severance Plans.”
Risk Assessment.Assessment. Management and the committee regularly evaluate the risks involved with our compensation programs. In January 2018,2020, we conducted a comprehensive risk assessment. The risk assessment includedafter compiling an inventory of incentive plans and programs and conducting an analysis of the risk involvedassociated with each. The assessment considered factors such as the plan metrics, number of plan participants, maximum payments, and risk mitigation factors. Exequity reviewed the risk assessment and advised the committee that it did not have any concerns aboutof its comfort with the level of risk assessment process or its conclusions.inherent in Olin’s compensation programs. Based on the committee’s review of the risk assessment and Exequity’s input, the committee concluded that it did not believe any of our compensation programs or policies create risks that are reasonably likely to have a material adverse impact on Olin. Based on this conclusion, we implemented no material changes to our compensation policies or practices after our risk assessment.

Change in Control Agreements.
We historically provided change in control agreements to our senior management to ensure that our executives work to secure the best outcome for shareholders in the event of a possible change in control, even if it means that they lose their jobs as a result. Currently, each of our NEOs and six other senior executives have agreements that provide certain benefits if the executive’s employment is terminated without cause or constructively terminated after a change in control.

We gave notice on August 23, 2016, that those agreements will terminate on January 26, 2019. The committee currently plans to replace those agreements with new change in control agreements at then-current market terms. The current change in control agreements with our NEOs are described in more detail under “Potential Payments Upon Termination or Change in Control.”

Tax and Accounting Considerations


Tax and Accounting Considerations
All elements of compensation, including salaries, generate charges to earnings under generally accepted accounting principles (GAAP). We generally do not adjust compensation based on accounting factors.

The committee considers the deductibility of long-term and annual incentive awards in structuring our executive compensation program, to the extent practical. To hire and retain highly skilled executives and remain competitive, the committee also looks at other factors. For example, historically, the committee considered thepre-2018 provisions of Code Section 162(m) which permitted deductions for performance-based compensation over $1 million. Prior to 2018, our stock options, the largest portion of our performance shares and our annual cash incentive were intended to meet this exemption for “performance-based” compensation from this Code Section 162(m) deductibility limit.

Code Section 409A implemented tax rules applicable to nonqualified deferred compensation arrangements, and Olin has taken steps to comply with such rules to the extent applicable.

As previously noted, Olin’s clawback policies allowpolicy allows recovery of all or a portion of payments under the SMICP or the MICPannual cash incentive program and performance share awards from executives who participate in the SMICPannual cash incentive or the MICP.Short Term Incentive Program. To recover compensation, our board or the committee must determine that the executive was grossly negligent or engaged in intentional misconduct that was a “significant contributing factor” to:

(i)

a restatement of our financial statements, or

(ii)

a significant increase in the value of that executive’s incentive awards.

(i) a restatement of our financial statements, or
(ii) a significant increase in the value of that executive’s incentive awards.
Amounts recovered are not included in calculating that executive’s benefits under our Supplemental CEOP, and do not trigger benefits under our severance agreements.plans. In addition, our equity plans provide that if a participant renders service to a competitor, or discloses confidential information without our consent, or violates other terms of the plan, the committee may terminate any unvested, unpaid or deferred awards held by the participant, or may require the participant to forfeit benefits received under the plan within the six months before the participant’s action.

Our equity plans and severance arrangements with NEOsplans do not provide any“gross-up” “gross-up” for the amount of excise tax, if any, due on “excess parachute payments” as defined under Code Section 280G. These agreementsbenefits are described in more detail under “Potential Payments Upon Termination or Change in Control.”

Stock Ownership Guidelines


Stock Ownership Guidelines

Our stock ownership guidelines require executive officers and certain other senior managers to maintain specified ownership levels of our stock within five years after the guideline applies. Once an officer or other employee covered by the guidelines meets his or her ownership target, such officer or other employee shall not later be deemed non-compliant solely based on a change in the share price of Olin stock. Stringent stock ownership requirements mitigate any risk that options may cause management to focus on short-term stock price movement.

Our committee monitors compliance with the stock ownership guidelines annually. To determine “stock ownership” under the guidelines, we include, in addition to shares the individual owns outright, restricted stock and restricted stock units, shares and phantom shares held in the executive’s CEOP and Supplemental CEOP accounts, and shares subject to vested stock options with an exercise price below the current market price and 25% of the total target performance share awards (representing half of the target performance shares that are payable in stock). Beginning in 2018, noprice. No unvested performance share awards will beare included in the determination of stock ownership.

(a)All of the accrued benefits under these plans were included in the required payments made in 2015 to participants in connection with our October 2015 acquisition of the U.S. chlor alkali and vinyl, global chlorinated organics and global epoxy business (the Acquisition) of Dow (Required NQ Plan Payments).
(b)Mr. Slater also received his accrued benefits in connection with the Acquisition, but because he was not yet of retirement-eligible age, he did not receive payment for this allowance. As of December 31, 2019, Mr. Slater became entitled to the value of the early retirement allowance (offset by the value of the accrued benefit) at retirement ages below age 65. The value of his remaining early retirement allowance is $31,029. The corresponding values of his remaining early retirement allowance as of December 31, 2017 and December 31, 2018 were $26,733 and $24,887, respectively
Changes in the present value of pension benefits are determined using the assumptions we use for financial reporting purposes and represent changes in assumptions and the fact that each NEO is one year older, rather than any change in the NEO’s accrued pension benefit. For December 31, 2017, the single effective rate (previously described as the ‘discount rate’) was 3.6% for the Qualified Plan and 3.3% for the Supplemental and Senior Plans. For December 31, 2018, the single effective rate (previously described as the ‘discount rate’) was 4.2% for the Qualified Plan and 3.9% for the Supplemental and Senior Plans. For 2019, the single effective rate (previously described as the “discount rate”) was 3.2% for the Qualified Plan and 2.8% for the Supplemental and Senior Plans. For 2017, 2018 and 2019, we used the RP2014

Proxy Statement Table of Contents
Blue Collar Mortality Tables for Annuitants and Employees, with the Social Security Administration—2014 Intermediate Cost Projections Mortality Improvement Scale (projection starting in 2007). Please see the note entitled “Pension Plans and Retirement Benefits” in the notes to our audited financial statements included in our 2019 annual report on Form 10-K for a discussion of these assumptions. The values shown in the table are due to the change of assumptions and the fact that each executive is one year older, as well as the Required NQ Plan Payments. It is not driven by any change in the retirement benefit itself, except for Messrs. Dawson and Varilek. The retirement benefits for Messrs. Dawson and Varilek reflect account balances based on a “pension equity plan” formula acquired from the Dow Employees’ Pension Plan (DEPP), which are then credited with interest until their assumed retirement date. As required by recent federal regulations, effective May 31, 2016, the rate of this credited interest changed from 8% to 6% for the DEPP equity account balances.
To determine the change in the present value of the pension benefits under these plans, for Mr. Slater, we used age 62, the first age at which unreduced pension benefits are payable under the Qualified Plan, the Supplemental Plan and 2015:

the Senior Plan. For Messrs. Fischer and McIntosh, who are eligible for unreduced pension benefits under the Qualified Plan, we used actual age at December 31, 2019. For Messrs. Dawson and Varilek, we used age 65, which is the retirement age at which they can receive their most valuable benefit due to the specific interest crediting feature of their DEPP account balances.
Generally, the Senior Plan provides a 50% benefit to the executive’s surviving spouse (which we refer to as a “joint and survivorship benefit”) without an actuarial reduction in payments during the executive’s lifetime. An executive also can elect to have payments under the Qualified Plan and the Supplemental Plan extend for the remainder of his or her spouse’s lifetime, but such an election results in an actuarial reduction to benefits paid under those plans. Benefits paid from the Senior Plan are increased by the amount of the actuarial reduction under the Qualified Plan and the Supplemental Plan for a 50% joint and survivorship benefit. However, the value of this benefit was included in the Required NQ Plan Payments. In accordance with the SEC regulations, the pension benefits in the Summary Compensation Table reflect benefits payable in the form of a single life annuity payable only during the life of the executive, and do not reflect any joint and survivorship benefit.

(a)Messrs. Dawson and Varilek receive life insurance in an amount equal to their base salary. The other NEOs participate in the key executive life insurance program, consisting of three types of benefits: active employee life insurance, retiree life insurance and survivor income benefits. In this program, at the executive’s option, the survivor income benefit may be exchanged for additional cash value. The amounts shown represent the total premiums we paid in 2019, for the benefits under the relevant program.
(b) The amounts shown represent Olin’s contributions of a total of 7.5% of eligible compensation to the Retirement Account portion of the CEOP and the Supplemental CEOP, as well as Olin matching contributions to the CEOP and the Supplemental CEOP during 2019.
(c) The amount in this column represents relocation payments on behalf of Mr. Varilek related to his transfer to corporate headquarters.

(1)

Messrs. Dawson and Varilek joined Olin in connection with the October 2015 acquisition of the U.S. chlor alkali and vinyl, global chlorinated organics and global epoxy business (the Acquisition) of Dow. The Acquisition triggered change in control provisions in four of our nonqualified pension and deferred compensation plans (the NQ Plans). We were unable to amend those provisions, which had been in effect for more than 30 years, because of the deferred compensation rules under Section 409A of the Code, and so were required to pay out all benefits previously accrued under those plans (the Required NQ Plan Payments). These payments are reflected in the “All Other Compensation” column for 2015 above, and represent benefits accrued by those NEOs over many years of prior service to Olin.

(2)

The NEOs were not entitled to receive payments which would be characterized as “Bonus” payments. Annual cash incentive payments under the SMICP appear in column (g). Each of the NEOs has one or more agreements that provide for certain severance benefits (including additional benefits in the event of a “change in control”), described in more detail under the section entitled “Potential Payments Upon Termination or Change in Control.”

(3)

Represents the aggregate grant date fair value of equity awards granted in that year (performance shares and restricted stock units in column (e) and options in column (f)), in each case calculated in accordance with ASC Topic 718.

Proxy Statement Table of Contents for the fiscal year in which the award was granted for a discussion of the assumptions underlying these calculations. The performance share amounts in column (e) are calculated based on a payout equal to 100% of the target level for awards made in 2015, 2016 and 2017. Set forth below are the amounts that would have been included for performance share awards (as well as the total amount in column (e)), if the grant date fair value had been based on the highest level of performance (for a payout equal to 150% of the target level for 2015 and 2016, and 200% for 2017).

(1) Amounts in these columns represent the potential annual cash incentives established in early 2019. Actual amounts were determined and paid in early 2020, and are included under column (g) in the Summary Compensation Table. We discuss our annual incentive program under the heading “COMPENSATION DISCUSSION AND ANALYSIS—What We Pay and Why: Elements of Compensation.”
(2) Numbers in these columns represent awards of performance shares under our Performance Share Program described below. The amounts in column (h) represent 200% of the target amounts, the maximum payout of the performance shares.
(3) Numbers in these columns for all NEOs represent nonqualified stock options granted under our long-term incentive plans, vesting in three equal annual installments, beginning on the first anniversary of the grant date. The market closing price on the grant date was $26.51, while the options were granted with an option exercise price equal to the average of the high and low sale prices of our common stock on the grant date ($26.26). Option awards are determined on the first regularly-scheduled committee meeting date in a calendar year (in 2019, January 24, 2019). In recent years, the option awards became effective approximately 10 business days after our year-end earnings release (February 19, 2019 for 2019 grants). The effective date of the option grants has always occurred after the meeting at which they are approved, and we have never engaged in “back dating” practices.
(4) Amounts in this column (i) assume payment of performance shares at the target level and (ii) value options using the Black-Scholes value, in each case calculated for financial statement reporting purposes in accordance with ASC Topic 718. Please see the note entitled “Stock-Based Compensation” in the notes to our audited financial statements included in our 2019 annual report on Form 10-K for a discussion of the assumptions underlying these calculations.
(5) Mr. Varilek received a one-time restricted stock unit award on April 1, 2019 vesting on April 1, 2022 in connection with his promotion to Executive Vice President and Chief Operating Officer.

(a)

All of the accrued benefits under these plans were included in the required payments made in 2015 to participants in connection with the Acquisition.

(b)

Mr. Slater also received his accrued benefits in connection with the Acquisition, but because he is not yet of retirement-eligible age, he is entitled to the value of the early retirement allowance (offset by the value of the accrued benefit) at retirement ages below age 65. The value of his remaining early retirement allowance is $26,733.

(c)

For Messrs. Dawson and Varilek, this amount reflects the period from October 5, 2015 through December 31, 2015.

Changes in the present value of pension benefits are determined using the assumptions we use for financial reporting purposes and represent changes in assumptions and the fact that each NEO is one year older, rather than any change in the NEO’s accrued pension benefit. For October 5, 2015, the single effective rate (previously described as the ‘discount rate’) was 4.3% for the Qualified Plan. For December 31, 2015, the single effective rate (previously described as the ‘discount rate’) was 4.4% for the Qualified Plan and 3.8% for the Supplemental and Senior Plans. For December 31, 2016, the single effective rate (previously described as the ‘discount rate’) was 4.1% for the Qualified Plan and 3.6% for the Supplemental and Senior Plans. For December 31, 2017, the single effective rate (previously described as the ‘discount rate’) was 3.6% for the Qualified Plan and 3.3% for the Supplemental and Senior Plans. For 2015, 2016 and 2017 we used the RP2014 Blue Collar Mortality Tables for Annuitants and Employees, with the Social Security Administration—2014 Intermediate Cost Projections Mortality Improvement Scale (projection starting in 2007). Please see the note entitled “Pension Plans and Retirement Benefits” in the notes to our audited financial statements included in our 2017 annual report onForm 10-K for a discussion of these assumptions. The values shown in the table are due to the change of assumptions and the fact that each executive is one year older, as well as the Required NQ Plan Payments. It is not driven by any change in the retirement benefit itself, except for Messrs. Dawson and Varilek. The retirement benefits for Messrs. Dawson and Varilek reflect account balances based on a “pension equity plan” formula acquired from the Dow Employees’ Pension Plan (DEPP), which are then credited with interest until their assumed retirement date. As required by recent federal regulations, effective May 31, 2016, the rate of this credited interest changed from 8% to 6% for the DEPP equity account balances.

Stock Options

To determine the change in the present value of the pension benefits under these plans, for Mr. Slater, we used age 62, the first age at which unreduced pension benefits are payable under the Qualified Plan, the Supplemental Plan and the Senior Plan. For Messrs. Fischer and McIntosh, who are eligible for unreduced pension benefits under the Qualified Plan, the Supplemental Plan and the Senior Plan, we used actual age at December 31, 2017. For Messrs. Dawson and Varilek, we used age 65, which is the retirement age at which they can receive their most valuable benefit due to the specific interest crediting feature of their DEPP account balances.

Generally, the Senior Plan provides a 50% benefit to the executive’s surviving spouse (which we refer to as a “joint and survivorship benefit”) without an actuarial reduction in payments during the executive’s lifetime. An executive also can elect to have payments under the Qualified Plan and the Supplemental Plan extend for the remainder of his or her spouse’s lifetime, but such an election results in an actuarial reduction to benefits paid under those plans. Benefits paid from the Senior Plan are increased by the amount of the actuarial reduction under the Qualified Plan and the Supplemental Plan for a 50% joint and survivorship benefit. However, the value of this benefit was included in the Required NQ Plan Payments. In accordance with the SEC regulations, the pension benefits in the Summary Compensation Table reflect benefits payable in the form of a single life annuity payable only during the life of the executive, and do not reflect any joint and survivorship benefit.

(a)

Messrs. Dawson and Varilek receive life insurance in an amount equal to their base salary. The other NEOs participate in the key executive life insurance program, consisting of three types of benefits: active employee life insurance, retiree life insurance and survivor income benefits. In this program, at the executive’s option, the survivor income benefit may be exchanged for additional cash value. The amounts shown represent the total premiums we paid in 2017, for the benefits under the relevant program.

(b)

For Messrs. Fischer, Slater, and McIntosh, the amounts shown represent Olin’s contributions of a total of 7.5% of eligible compensation to the Retirement Account portion of the CEOP and the Supplemental CEOP, as well as Olin matching contributions to the CEOP and the Supplemental CEOP during 2017. For Messrs. Dawson and Varilek, the amounts shown represent Olin’s contributions of 10% of their eligible compensation to the Retirement Account portion of the CEOP.

(c)

Amounts in this column for Mr. Dawson consist of an additional $921,000 cash bonus and $58,433 transitional cash payment required by the terms of the agreements signed in connection with the Acquisition and $8,410 in payments for his relocation to our corporate headquarters, and for Mr. Varilek, an additional $606,750 cash bonus and $53,891 transitional cash payment required by the terms of the agreements signed in connection with the Acquisition and $18,985 in payments for his relocation to our corporate headquarters (including $446 taxgross-up).

Amounts in these columns represent the potential annual cash incentives established in early 2017, under our SMICP. Actual amounts were determined and paid in early 2018, and are included under column (g) in the Summary Compensation Table. We discuss the SMICP and our annual incentive program under the heading “COMPENSATION DISCUSSION AND ANALYSIS—What We Pay and Why: Elements of Compensation”.

(2)

Numbers in these columns represent awards of performance shares under our Performance Share Program described below. The amounts in column (h) represent 200% of the target amounts, the maximum payout of the performance shares.

(3)

Numbers in these columns for all NEOs represent nonqualified stock options granted under our long-term incentive plans, vesting in three equal annual installments, beginning on the first anniversary of the grant date. The market closing price on the grant date was $29.81, while the options were granted with an option exercise price equal to the average of the high and low sale prices of our common stock on the grant date ($29.75). Option awards are determined on the first regularly-scheduled committee meeting date in a calendar year (in 2017, January 26, 2017). In recent years, committee meetings have been held before (or shortly after) the time we issued ouryear-end earnings press release, and so the option awards became effective on a later date (February 10, 2017 for 2017 grants), approximately 10 days after our earnings release. The effective date of the option grants has always occurred on or after the meeting date, and we have never engaged in “back dating” practices.

(4)

Amounts in this column (i) assume payment of performance shares at the maximum level and (ii) value options using the Black-Scholes value calculated for financial statement reporting purposes in accordance with ASC Topic 718. Please see the note entitled “Stock-Based Compensation” in the notes to our audited financial statements included in our 2017 annual report on Form 10-K for a discussion of the assumptions underlying these calculations.

Stock Options


Annually, we grantthe committee grants options to purchase shares of our common stock to a group of key employees, including our executive officers. We describe our stock option program in more detail under the heading “COMPENSATION DISCUSSION AND ANALYSIS—Long-Term Incentive (Equity) Compensation—Stock Options.” All options granted in 2017,2019 were nonqualified options vesting in three equal annual installments beginning on the first anniversary of the grant date. The options generally may be exercised until 10 years after the grant date (but the exercise period may end earlier based on the termination of the participant’s employment).

The committee grants options with an exercise price equal to the average of the high and low prices on the grant effective date. All of our equity plans specifically prohibit repricing, and, except for certain anti-dilution adjustments, other adjustments to the exercise price. We discuss the timing of our option grants under the heading “COMPENSATION DISCUSSION AND ANALYSIS—Long-Term Incentive (Equity) Compensation—Stock Options”.Options.” Our plans and our policies do not permit any “back dating” of options.

Performance Shares


Performance Shares
Each NEO and certain other key employees received a target number of performance shares in early 2017,2019, which vest at the end of 2019.2021. The total number of performance shares that vest may vary between 0 and 200% of the target number, with half of the performance shares based on TSR over a three-year period compared to the TSR of the companies in the Performance Share Comparison Group and the remaining half based on our net income performance compared to the net income goal set by the committee for the same three-year period. The chart included in the discussion of performance share awards above sets forth this relationship in more detail. Vested performance shares are paid approximately half in cash and half in stock. No dividends or dividend equivalents are paid on unvested performance shares.

The amounts in column (c) above represent the difference between the closing market price of the underlying shares on the exercise date and the option exercise price, multiplied by the number of shares subject to the option exercise. Messrs. Fischer, Slater and McIntosh retained 19,942, 3,790 and 16,070, respectively, of the shares issued on exercise, so their actual cash value realized was less than the amount shown above.

Our equityplan (the Olin Corporation 2018 Long Term Incentive Plan) allows for the award of restricted stock or restricted stock units by the committee. The CEO also has authority to grant a limited number of restricted stock (no more than 60,000 total shares or 5,000 shares per employee) but may not grant restricted stock to anyone who is an officer within the definition of the rules under Section 16 of the Exchange Act. Under our equity plan, any restricted stock awards must vest over at least three years, or vest no earlier than one year if tied to a performance objective. The committee does not award restricted stock or restricted stock units to NEOs on any regular basis. We describe recent awards of restricted stock units to NEOs under the heading “COMPENSATION DISCUSSION AND ANALYSIS—Long-Term Incentive (Equity) Compensation—Restricted Stock.”

The amounts in the DEPP for Messrs. Dawson and Varilek were rolled into the Qualified Plan at the time of the Acquisition and their benefit accruals were frozen at that time. For the other NEOs, benefit accruals were frozen under all three plans effective December 31, 2007. Employment after that date continues to count toward meeting service and age requirements for vesting and early retirement. Participation in the Senior Plan began when the executive became a Section 16(b) reporting officer and was selected by the committee (prior to the accrual freeze in 2007). Participation in the Qualified Plan generally began when the executive was hired. Participation in the Supplemental Plan generally began when the executive’s compensation first exceeded the limit imposed by the Code on compensation that was includible when determining benefits under qualified plans (other than Messrs. Dawson and Varilek, who do not participate in this plan). All of the participating NEOs have met the requirements for vesting. Messrs. Fischer and McIntosh have met the requirements for full retirement.

Amounts in this column assume that benefits are paid in the form of an annuity during the executive’s lifetime. As discussed in more detail below, a participant may elect instead to receive benefits over the life of the executive and his or her spouse. For the legacy DEPP benefits, transferred from Dow, the normal form of married participants is 50% joint & survivorship benefit.

(3)As described in more detail below, all amounts under the Supplemental Plan and Senior Plan were paid out to the NEOs in connection with the Acquisition. At the time of the Acquisition, Mr. Slater had not reached retirement age and so has a residual benefit under these plans. Information regarding the present value of Mr. Slater’s residual benefits under these two plans as of December 31, 2019 is set forth below.

These amounts were calculated using the assumptions set forth in the table above for the Qualified Plan. In addition, the Supplemental Plan and Senior Plan use a 2.8% single effective rate (in lieu of a discount rate) and the RP2014 Blue Collar Mortality Tables for Annuitants and Employees with the Social Security Administration—2014 Intermediate Cost Projections Mortality Improvement Scale (projection starting in 2007). Mr. Slater began participating in the Senior Plan when he became a Section 16(b) reporting officer and was selected by the committee and began participating in the Supplemental Plan when Mr. Slater’s compensation that was includible when determining benefits under qualified plans first exceeded the limit imposed by the Code.
The executive may elect payment of benefits under any of the available payment forms under these plans, including payments for the executive’s life (which we sometimes refer to as a “single life annuity”) or payments continuing after the executive’s death for the life of his or her spouse (which we refer to as a “joint and survivorship benefit”). Under the Qualified Plan and the Supplemental Plan, benefit payments are reduced from the single life annuity based on actuarial calculations if the executive elects a different payment form. The Senior Plan generally provides a 50% joint and survivorship benefit without any actuarial reduction, and also provides the executive with an additional amount equal to the amount of the actuarial reduction of benefits payable from the Qualified Plan and the Supplemental Plan for a 50% joint and survivorship benefit election.

The following chart shows the present value of accrued benefits for each of the NEOs who participate in these plans, assuming (i) the executive elected the 50% joint and survivorship benefit and (ii) for Mr. Slater, that he retired at age 62 (the first age at which unreduced pension benefits are payable under the plans), (iii) for Messrs. Fischer and McIntosh that they retired on December 31, 2017,2019, as they are currently eligible for unreduced benefits, and (iv) for Messrs. Dawson and Varilek that they retired at age 65 (the retirement age at which they can receive their most valuable benefit due to the interest crediting feature of their DEPP account balances).

Freeze of Qualified Plan, Supplemental Plan and Senior Plan



Freeze of Qualified Plan, Supplemental Plan and Senior Plan
As part of our ongoing evaluation of benefit plans, in 2005, we amended the Qualified Plan to close participation, so that salaried employees hired on or after January 1, 2005, are not eligible for the Qualified Plan. Benefits accrued by most salaried participants in the Qualified Plan, Supplemental Plan and Senior Plan were “frozen” effective December 31, 2007, and benefits for former Dow employees were assumed by the Qualified Plan and frozen on October 5, 2015, but continue to accrue interest. Participants accrued benefits until December 31, 2007, based on applicable years of service and eligible compensation through that date. Service after December 31, 2007, will count toward meeting the eligibility

Proxy Statement Table of Contents
requirements for commencing a pension benefit (including vesting and early retirement) under these plans, but not toward the calculation of the pension benefit amount. Compensation earned after 2007 will similarly not count toward the determination of the pension benefit amounts under these plans.

As described above, all of the previously accrued benefits under these Olin plans were required to be paid as part of the Required NQ Plan Payments in connection with the Acquisition. We describeMr. Slater, who was not yet retirement-eligible at the terms of our retirement plans in more detail in the narrative discussion following the table entitled “Pension Benefits”.

Implicationstime of the Acquisition, on Qualified Plan, Supplemental Plan and Senior Plan


As described above, previously accrued benefits under the Supplemental Plan and Senior Plan were required to be paid to participants as part of the Required NQ Plan Payments in connection with the Acquisition under the “change in control” provisions of these two plans. Accordingly, participants of these plans no longer have an accrued benefit under the plans. Note, however, that participants not yet retirement-eligible may become eligible upon early-retirementearly retirement for an early-retirementearly retirement benefit (offset by the value of the accrued benefit paid as part of the Required NQ Plan Payments).

In addition, in connection with the Acquisition, the Qualified Plan is now responsible for certainDow-related frozen benefits described below for which the Qualified Plan received certain assets from the appropriate Dow pension plans. We describe the terms of our retirement plans in more detail in the narrative discussion below.


Qualified Plan


Qualified Plan
As part of our benefits program, we offered defined benefit retirement benefits to salaried employees hired before January 1, 2005, through our Qualified Plan. Benefits under the Qualified Plan are calculated based on the average cash compensation (salary and annual incentive) for the highest three years out of the last 10 years the individual was employed by Olin, through December 31, 2007. The law requires that in determining eligible compensation, the Qualified Plan ignoreignores compensation in excess of a legally-imposed cap (which for 2007, the last year of benefit accruals, was $225,000). An employee’s benefit is generally 1.5% of his or her average compensation during the relevant period multiplied by the number of years of service, less a percentage of his or her primary Social Security benefit based on years of service (not to exceed 50% of such Social Security benefit). Participants who

are at least age 55 with at least 10 years of service when they leave Olin may elect to receive a benefit immediately that is reduced by 4% for each year the participant is younger than age 62 at the time benefit payments begin. Participants who leave Olin before age 55 (with 10 or more years of service) may elect to receive an actuarially reduced benefit with payments beginning at age 55 or later. Participants who leave Olin before age 65 with at least five years of service (but less than 10 years of service) receive a vested retirement benefit beginning the month after their 65th65th birthday. Benefits from the Qualified Plan generally are paid as an annuity with the form of payment (e.g. joint and survivorship benefit, guaranteed period, etc.) selected by the participant, subject to any applicable actuarial reductions.

In conjunction with the Acquisition, the Qualified Plan assumed responsibility for certainDow-related frozen benefits. Specifically, nearly all frozen benefits transferred to the Qualified Plan are associated with two benefit formulae—Pension Equity and Cash Balance—eligibility for which is typically determined by the individual participant’s hire date at Dow. The Pension Equity provides a frozen account balance that grows with interest until retirement (which can commence upon separation from Olin), at which time it is converted into a monthly pension benefit. The Cash Balance also provides a frozen account balance that grows with interest (at a different rate) until separation from Olin, at which point the participant can elect an immediate annuity, a deferred annuity or a lump sum. Messrs. Dawson and Varilek are participants of the Pension Equity arrangement.

In lieu of benefits that had been provided under the Qualified Plan, at the time participation was frozen, the CEOP was amended to add a Defined Contribution Retirement Account to help ensure that our benefits program would remain competitive. Depending on the participant’s age, and whether they joined Olin in connection with the Acquisition, we generally contribute 5%, or 7.5% or 10% of eligible compensation to that Defined Contribution Retirement Account.

Supplemental Plan


Supplemental Plan
The Supplemental Plan is an unfunded, nonqualified deferred compensation plan for management employees at specified compensation levels. The Code imposes limits on pension benefits payable from the Qualified Plan. Our Supplemental Plan restores these benefits to affected employees and provides benefits on certain compensation that has been excluded from eligible compensation under the Qualified Plan. The formula used to calculate pension benefits under the Supplemental Plan is the same as under the Qualified Plan, without the Code limitations on benefits and eligible compensation, reduced for the amount payable under the Qualified Plan. Early retirement benefits are payable at the later of termination or age 55 if a participant has at least 10 years of service. Such early retirement benefits use the same reduction factors as the Qualified Plan.

As noted above, previously accrued benefits in the Supplemental Plan were required to be paid to participants as part of the Required NQ Plan Payments in connection with the Acquisition.

An employee who was a Section 16(b) reporting officer, and was selected by the committee prior to the date of the freeze, participates in the Senior Plan. Under the Senior Plan, pension benefits are based on average eligible compensation for the three highest years out of the last 10 years that he or she is employed by Olin through December 31, 2007. Compensation is not subject to the Code and other limitations that apply under the Qualified Plan. Benefits generally equal 3% of the executive’s average compensation multiplied by the number of years of participation in the Senior Plan, plus 1.5% of the executive’s average compensation for years of service in the Qualified Plan and

Supplemental Plan less years of service in the Senior Plan, reduced by the pension benefits accrued under the Qualified Plan and the Supplemental Plan. Benefits are further reduced by 50% of the employee’s primary Social Security benefit.

Early retirement benefits are payable on an immediate basis to a participant whose employment terminates at age 55 or later, regardless of years of service, but are reduced by 4% per year for each year they begin before age 62. The maximum benefit payable from the Senior Plan is 50% of the employee’s average compensation reduced by amounts payable from the Qualified and Supplemental Plans, 50% of the employee’s primary Social Security benefit, and certain other adjustments set forth in the plan documents, if applicable. The Senior Plan provides a joint and survivorship benefit to an executive’s surviving spouse generally equal to 50% of the executive’s benefits from the Senior Plan. In addition, the Senior Plan pension benefits are increased by the amount of the actuarial reduction to benefits under the Qualified and Supplemental Plans if the executive elects the 50% joint and survivorship option under those plans.

The executive may elect any of the forms of payment available under the Senior Plan and Supplemental Plan, including a lump sum payment or the annuity form of payment.

If a participant in the Senior Plan and Supplemental Plan is a specified employee as defined in Code Section 409A, benefits payable upon termination of employment may not be paid in the first six months after retirement, but the first six months of benefits will be paid in a lump sum as soon as practicable thereafter.

As noted above, previously accrued benefits in the Senior Plan were required to be paid to participants as part of the Required NQ Plan Payments in connection with the Acquisition.

Health Insurance and Death Benefits


Health Insurance and Death Benefits
In general, salaried employees who retire at age 55 or later with at least 10 years of service may elect to continue to be covered under our health plan until age 65 by paying at least the same premium as active salaried employees. When the average per capita cost for our health plan exceeds $10,000, as it did in 2015 and 2016, the retiree also must pay the amount by which our average per capita cost for the health plan exceeds $10,000. On the first day of the month in which they become 65, salaried retirees who retired after age 55 with 10 or more years of service are eligible for a Medicare supplemental health care plan. We contribute $20 per covered person per month toward the cost of that plan, but make no contributions if a retiree chooses to participate in another plan. Olin made the decision to discontinue providing retiree health insurance benefits for salaried employees hired after November 23, 2009, so Messrs. Dawson and Varilek are not eligible for this benefit.

In general, salaried employees who retire from Olin under the Qualified Plan at age 55 or later with at least 10 years of service are eligible for a $5,000 death benefit from the Qualified Plan. In addition, full-time employees with job responsibilities at a specified level (based on Hay Points) may retain a percentage of their life insurance coverage when they retire, based on age at retirement, with Olin paying the premiums.

In addition to our CEOP, discussed under the heading “COMPENSATION DISCUSSION AND ANALYSIS—What We Pay and Why: Elements of Compensation—Retirement Benefits,” our Supplemental CEOP provides deferral and company matching opportunities to employees eligible to participate in the CEOP whose contributions to the CEOP are limited under the Code because their base pay exceeds the Code’s compensation limit ($270,000280,000 for 2017)2019). These employees can makepre-tax contributions to the Supplemental CEOP after their eligible compensation reaches the Code limit. For these purposes, eligible compensation generally includes base compensation but excludes incentive compensation. Employees who contribute to the Supplemental CEOP receive matching contribution credits from Olin at the same level Olin matches CEOP contributions. In addition, in connection with the pension plan freeze, Olin generally provides the same retirement contribution credits to the Supplemental CEOP as under the CEOP (5% or 7.5%, depending on the employee’s age) on the amount of the excess eligible compensation, except that former Dow employees receive only matching benefits under the Supplemental CEOP, to mirror their benefits while at Dow.compensation. For these purposes, eligible compensation generally includes base compensation and short-term incentive compensation but excludes long-term incentive compensation.

Employees elect to have their contributions to the Supplemental CEOP invested in phantom shares of Olin common stock or phantom units in an interest bearing fund. Dividends are credited to the phantom stock account based on the dividend rate paid on shares of our common stock. Interest is credited to the phantom interest bearing fund at a rate determined quarterly equal to (i) the Federal Reserve A1/P1 Composite rate for90-day commercial paper at the end of the last quarter plus 10 basis points, or (ii) such other rate as our board or committee (or any delegate thereof) selects in advance from time to time.

Distributions are paid in cash, in a lump sum or in annual installments for up to 15 years after retirement, at the employee’s election. Our phantom shares of common stock are valued at the average daily closing prices of our common stock on the NYSE for the month before the distribution. Distributions from the interest bearing fund equal the dollar value of the participant’s account (principal and interest). If a participant in the Supplemental CEOP is a specified employee as defined in Code Section 409A, benefit payments payable upon termination of employment generally may not be paid in the first six months after retirement.

Amounts in the tables assume an annual base salary at the level in effect on December 31, 2017.

Proxy Statement Table of Contents

(2)

Messrs. Fischer and McIntosh are eligible for normal retirement (age 62), so amounts in both the “Quit/Early Retirement” and in the “Normal Retirement” columns represent amounts they would receive upon full retirement. Mr. Slater has met the vesting requirements, but is not yet early retirement age, so the amounts reported for him under the “Benefits and Perquisites” section represent the present value of the benefits, assuming the benefits begin at age 65, except for ‘Termination without Cause’ and ‘Change in Control’, which assume benefits begin at age 55 (because he is within 3 years of early retirement age). Messrs. Dawson and Varilek are each eligible to receive benefits based on his account balance at termination, so all amounts reflect immediate commencement of benefits.

(3)

Under their Executive Agreements, upon termination without cause each NEO is eligible to receive a contribution to the Supplemental CEOP Defined Contribution Retirement Account based on the amount of severance received. An executive whose employment terminates in connection with the sale of a business unit generally receives the benefits in this column, except that the executive’s stock options may be exercised for two years beyond the date of termination (rather than one year), unless the employee is eligible for retirement in which case the executive’s stock options would be exercisable through the term of the option.

(4)

Olin generally may terminate an executive for “cause” if the executive (i) willfully fails to perform his or her duties; (ii) engages in gross misconduct that significantly injures Olin financially; (iii) commits a felony or fraud in the course of his or her employment; or (iv) willfully breaches Olin’s Code of Conduct.

(5)

A portion of the amounts for Messrs. Fischer, Slater, Dawson and Varilek constitute “excess parachute payments” under Section 280G of the Code subject to a 20% excise tax payable by the officer. Benefits listed for the Senior Plan and Supplemental Plan (collectively, the “defined benefit plans”) and the Supplemental CEOP would be payable immediately upon a change in control (as defined under these plans). Because the NEOs are specified employees as defined in Code Section 409A, however, benefits may not be paid in the first six months after retirement, but will be paid in a lump sum as soon as practicable thereafter. The benefits reported represent the present value of the benefits under the defined benefit plans on December 31, 2017, and the market value of the phantom investments in the Supplemental CEOP account, plus a contribution to the Defined Contribution Retirement Account based on the amount of severance received. Footnote 8 describes the treatment of equity awards upon a change in control.

(6)

For the NEOs other than Messrs. Slater, Dawson and Varilek, severance payments for a termination without cause equal base salary plus a percentage (calculated as the executive’s target bonus for the prior fiscal year divided by the executive’s salary in effect at termination) of base salary. Under our standard severance policy, they would have received severance upon termination without cause in the respective amounts set forth above, based on years of service and base pay at the time of termination. Under the agreements, in the event of a change in control, (a) Mr. Fischer would have received severance payments equal to three times the executive’s base salary plus the higher of his target incentive award under the SMICP or MICP or his average SMICP or MICP payment during the past three years, (b) Mr. McIntosh would have received apro-rated portion of this payment, based on the remaining number of days until he attains age 66, divided by 1,095 (three years), and (c) Messrs. Slater, Varilek and Dawson would have received severance payments equal to two times the executive’s base salary plus the higher of his target incentive award under the SMICP or MICP or his average SMICP or MICP payment during the past three years. In addition, Messrs. Dawson and Varilek would each receive any unpaid retention payments under the retention agreements executed with former Dow executives. The change in control agreements, executive retention agreements and executive severance agreements are described under the heading “Executive Severance and Executive Change in Control Agreements.” In the event of retirement or termination without cause, all NEOs, like all other employees also receive a prorated bonus (based on the portion of the year that the NEO was employed), paid at the time other bonuses are determined and paid.

(7)

We have assumed payouts at the level of 50% of the target unvested performance shares and performance shares vested at December 31, 2017, but not yet paid. Under the performance share program, an executive whose employment terminates as the result of disability or retirement receives a pro rata share of unvested performance share awards (based on actual Olin performance for the full performance period and the number of months worked in the performance cycle) payable in cash at the time it would otherwise be payable. In the event of an executive’s death before performance shares have vested, his estate receives a pro rata share of his target award in cash. An executive whose employment terminates for cause or without our consent does not receive any unvested performance awards. All unvested performance shares vest on a change in control and are paid in cash. The committee determines the amount, if any, of unvested performance awards to be paid and the form of payment (cash or stock or a combination) for an executive whose employment terminates for any other reason. Upon the executive’s death, all unvested options vest automatically and his or her estate or heirs could exercise those options within the term of the option.

(8)

Amounts in this line represent a cash payout of all restricted stock, stock options and performance shares that were unvested at December 31, 2017. Under equity plans and severance agreements (a) all performance share awards would have vested and been paid upon a change in control (as defined for these awards), and (b) all restricted stock awards and options would have remained outstanding, and would accelerate and vest upon a change in control only if the acquirer does

not assume or replace those equity awards or there is a termination of employment without cause or a constructive termination within three years after the change in control. Constructive termination occurs when the executive terminates his or her employment (after appropriate notice and an opportunity to cure) because (i) Olin requires the executive to relocate by more than fifty miles; (ii) Olin reduces or fails to increase the executive’s base salary on a basis consistent with the salary system for executive officers in place before the change in control; (iii) Olin fails to maintain executive’s incentive compensation plans or health, welfare and retirement plans on substantially the terms in effect prior to the change in control; or (iv) the executive is assigned duties inconsistent with the executive’s position prior to the change in control, or Olin takes actions that result in a diminution of the executive’s responsibilities or a substantial reduction in resources to carry out his duties.

Unused vacation for the current year is paid to all salaried employees and is therefore not included in this table. Medical benefits are provided to all salaried employees hired prior to November 23, 2009, who are eligible for early retirement. Messrs. Fischer and McIntosh are currently eligible for full retirement, so no amount is reported for medical benefits for either of them. Under our severance policy, Messrs. Slater, Dawson and Varilek would be eligible for healthcare coverage while receiving severance payments in the event of a without cause termination. In the event of a change in control, Messrs. Slater, Dawson and Varilek would be eligible for healthcare coverage for 24 months at an estimated cost of $31,000.

(10)

An executive may elect payment of benefits in any of the available payment forms under the defined benefit plans. Under the Supplemental Plan (applicable only to Mr. Slater) and the Qualified Plan, benefit payments are reduced on an actuarial basis, if the executive elects a form of payment other than a lifetime annuity. The Senior Plan (applicable only to Mr. Slater) provides a 50% joint and survivorship benefit without an actuarial reduction. In addition, pension benefits paid from the Senior Plan are increased by the amount of the actuarial reduction for a 50% joint and survivorship benefit under the Qualified Plan and the Supplemental Plan. The value of the 50% joint and survivorship benefit is reflected in the lump sum pension benefits in the table above with respect to the Senior Plan. The Qualified Plan and Supplemental Plan benefits above assume payment in the form of a joint and survivorship benefit. The executive may also elect to receive benefits from the Senior Plan and the Supplemental Plan in the form of a lump sum. Any payment payable upon termination of employment is paid six months after termination of employment to comply with Code limitations. The value of these benefits is determined using a discount rate that is equal to the rate for a zero coupon Treasury strip, with a maturity that approximates the executive’s life expectancy, determined approximately at the time the lump sum is due to be paid and the RP2014 Blue Collar Mortality Tables for Annuitants and Employees with the Social Security Administration—2014 Intermediate Cost Projections Mortality Improvement Scale (projected from 2007). Except with respect to a change in control, the benefits reported for the Senior Plan and Supplemental Plan are based on these assumptions and also include six months of payments in recognition of the deferral of the commencement of benefits required by Code Section 409A.

In the event of a change in control (as defined under the Senior Plan and the Supplemental Plan), each executive participating in the relevant plan receives a cash payment in an amount equal to the cost to purchase an annuity that pays benefits to the executive in an amount such that the annuity payments (together with the monthly payment to the executive from the Qualified Plan) provide the executive with the monthlyafter-tax benefit he or she would have received under the plans. The amounts in the table represent this lump sum cash payment.

The benefit amounts reported in each of the columns above assume a 50% joint and survivorship benefit and use the discount rate applicable for the situation described and the RP2014 Blue Collar Mortality Tables for Annuitants and Employees with the Social Security Administration—2014 Intermediate Cost Projections Mortality Improvement Scale (projected from 2007). If the participating executive instead elects annual payments for his or her lifetime, he or she would receive an annual amount from each of the defined benefit pension plans as follows:

____________________

(1)Amounts in the tables assume an annual base salary at the level in effect on December 31, 2019.  
(2) Messrs. Fischer and McIntosh are eligible for normal retirement (age 62), so amounts in both the “Quit/Early Retirement” and in the “Normal Retirement” columns represent amounts they would receive upon full retirement. Mr. Slater is not yet eligible for normal retirement but is eligible for early retirement and amounts reported under the “Quit/Early Retirement” column reflect amounts he would receive upon early retirement. Messrs. Dawson and Varilek are each eligible to receive benefits based on his account balance at termination, so all amounts reflect immediate commencement of benefits.As of December 31, 2018, under agreements then in effect, upon termination without

cause each NEO is eligible to receive a contribution to the Supplemental CEOP Defined Contribution Retirement Account based on the amount of severance received. An executive whose employment terminates in connection with the sale of a business unit generally receives the benefits in this column, except that the executive’s stock options may be exercised for two years beyond the date of termination (rather than one year), unless the employee is eligible for retirement in which case the executive’s stock options would be exercisable through the term of the option.
(3) As of December 31, 2019, under the Plans then in effect, an executive whose employment terminates in connection with the sale of a business unit generally receives the benefits in this column, except that the executive’s stock options may be exercised for two years beyond the date of the termination (rather than one year), unless the employee is eligible for retirement in which case the executive’s stock options would be exercisable through the original term of the option.
(4) Olin generally may terminate an executive for “cause” if the executive (i) willfully fails to perform his or her duties; (ii) engages in gross misconduct that significantly injures Olin financially; (iii) commits a felony or fraud in the course of his or her employment; or (iv) willfully breaches Olin’s Code of Conduct.
(5) Amounts for Messrs. Fischer and Varilek represent the amounts they would receive on the “best net after-tax” payment approach contemplated by the Olin Corporation Change in Control Severance Plan for Section 16(b) Officers (CIC Severance Plan) described in more detail below. Without the reduction, the amounts for Messrs. Fischer and Varilek would have increased by $2,578,137 and $215,007, respectively. A portion of the amounts for Messrs. Fischer and Varilek constitute “excess parachute payments” under Section 280G of the Code subject to a 20% excise tax payable by the officer. Benefits listed for the Senior Plan and Supplemental Plan (collectively, the “defined benefit plans”) and the Supplemental CEOP would be payable immediately upon a change in control (as defined under these plans). However, because the NEOs are specified employees as defined in Code Section 409A, benefits may not be paid in the first six months after retirement but will be paid in a lump sum as soon as practicable thereafter. The benefits reported represent the present value of the benefits under the defined benefit plans on December 31, 2019 and the market value of the phantom investments in the Supplemental CEOP account. Footnote 8 describes the treatment of equity awards upon a change in control.
(6) For the NEOs, severance payments for a termination without “cause” equal base salary plus the participant’s target bonus opportunity under the STIP. For terminations occurring during or after the second quarter of the calendar year of the qualifying termination, the participant will be entitled to receive a payout of their current year bonus, determined by multiplying the average actual payout (as a percentage of the annual STIP target) for all participants in the STIP in the same organization unit by a fraction, the numerator of which is the number of full weeks in the calendar year prior to the qualifying termination and the denominator of which is 52. In the event of a change in control, the NEOs’ severance payments would be determined in the same manner as described above, except that under the CIC Severance Plan, Mr. Fischer would receive three times the calculated severance value and the other NEOs would receive a multiple of two times the calculated severance value.
(7) For performance shares vested as of December 31, 2019, but not paid as of that date, the amount of the vested performance shares is included. All unvested performance shares vest on a change in control and are paid in cash at the target level. An executive whose employment terminates for “cause” or without our consent does not receive any unvested performance awards. For all other events, we have assumed payouts at 50% of the target unvested performance shares. Under the performance share program, an executive whose employment terminates as the result of disability or retirement receives a pro rata share of unvested performance share awards (based on actual Olin performance for the full performance period and the number of months worked in the performance cycle) payable in cash at the time it would otherwise be payable. In the event of an executive’s death before performance shares have vested, his estate receives a pro rata share of his target award in cash. The committee determines the amount, if any, of unvested performance awards to be paid and the form of payment (cash or stock or a combination) for an executive whose employment terminates for any other reason. Upon the executive’s death, all unvested options vest automatically and his or her estate or heirs could exercise those options within the term of the option.
(8) Amounts in this line represent a cash payout of all stock options and performance shares that were not vested at December 31, 2019. Under equity plans and severance plans (a) all performance share awards vest at target level and are paid upon a change in control (as defined for these awards), and (b) all restricted stock awards and options remain outstanding, and accelerate and vest upon a change in control only if the acquirer does not assume or replace those equity awards or there is a termination of employment without “cause” or a constructive termination within three years after the change in control. Constructive termination occurs when the executive terminates his or her employment (after appropriate notice and an opportunity to cure) because (i) the executive is required to relocate by more than fifty miles; (ii) the executive’s base salary is reduced or is not increased on a basis consistent with the salary system for executive officers in place before the change in control; (iii) the employer fails to maintain the
56

executive’s incentive compensation plans or health, welfare and retirement plans on substantially the terms in effect prior to the change in control; or (iv) the executive is assigned duties inconsistent with the executive’s position prior to the change in control, or (v) the employer takes actions that result in a diminution of the executive’s responsibilities or a substantial reduction in resources to carry out his duties.
(9) Unused vacation for the current year is paid to all salaried employees and is therefore not included in this table. Medical benefits are provided to all salaried employees hired prior to November 23, 2009, who are eligible for early retirement. Messrs. Fischer and McIntosh are currently eligible for full retirement, so no amount is reported for medical benefits for either of them. Under our severance policy, Messrs. Slater, Dawson and Varilek would be eligible for healthcare coverage while receiving severance payments in the event of a termination without “cause.” In the event of a change in control, Messrs. Slater, Dawson and Varilek would be eligible for healthcare coverage for 24 months at an estimated cost of $33,000.
(10) An executive may elect payment of benefits in any of the available payment forms under the defined benefit plans. Under the Supplemental Plan (applicable only to Mr. Slater) and the Qualified Plan, benefit payments are reduced on an actuarial basis, if the executive elects a form of payment other than a lifetime annuity. The Senior Plan (applicable only to Mr. Slater) provides a 50% joint and survivorship benefit without an actuarial reduction. In addition, pension benefits paid from the Senior Plan are increased by the amount of the actuarial reduction for a 50% joint and survivorship benefit under the Qualified Plan and the Supplemental Plan. The value of the 50% joint and survivorship benefit is reflected in the lump sum pension benefits in the table above with respect to the Senior Plan. The Qualified Plan and Supplemental Plan benefits above assume payment in the form of a joint and survivorship benefit. The executive may also elect to receive benefits from the Senior Plan and the Supplemental Plan in the form of a lump sum. Any amount payable upon termination of employment is paid six months after termination to comply with Code limitations. The value of these benefits is determined using a discount rate equal to the rate for a zero coupon Treasury strip, with a maturity that approximates the executive’s life expectancy, determined approximately at the time the lump sum is due to be paid based on the RP2014 Blue Collar Mortality Tables for Annuitants and Employees with the Social Security Administration—2014 Intermediate Cost Projections Mortality Improvement Scale (projected from 2007). Except with respect to a change in control, the benefits reported for the Senior Plan and Supplemental Plan are based on these assumptions and also include six months of payments in recognition of the deferral of the commencement of benefits required by Code Section 409A.
In the event of a change in control, each executive participating in the relevant plan receives a cash payment in an amount equal to the cost to purchase an annuity that pays benefits to the executive in an amount such that the annuity payments (together with the monthly payment to the executive from the Qualified Plan) provide the executive with the monthly after-tax benefit he or she would have received under the plans. The amounts in the table represent this lump sum cash payment.
The benefit amounts reported in each of the columns above assume a 50% joint and survivorship benefit and use the discount rate applicable for the situation described and the RP2014 Blue Collar Mortality Tables for Annuitants and Employees with the Social Security Administration—2014 Intermediate Cost Projections Mortality Improvement Scale (projected from 2007). If the participating executive instead elects annual payments for his or her lifetime, he or she would receive an annual amount from each of the defined benefit pension plans as follows:

Payments Upon Death or Disability

Payments Upon Death or Disability


Upon the death of a former executive, unless the executive elects to receive the cash value of his or her life insurance at retirement, his or her estate receives life insurance benefits provided the former executive was at least age 55 when employment terminated. Messrs. Dawson and Varilek do not participate in this program, but the other NEOs have attained the age of 55, except Mr. Slater. The amount of life insurance is based on the executive’s age and base salary at the time of termination of employment. Set forth below are the cash value amounts of this life insurance coverage for each of the NEOs as of December 31, 2017:

If the employment of Messrs. Fischer, Slater or McIntoshan NEO terminates in connection with a disability, he would receive disability benefits equal to 60% of base salary until the executive is no longer disabled or elects to take early retirement benefits or reaches the age of 65 (except in the case of an employee who is over age 61 at the time the disability occurs). If the disability occurs after age 61, the maximum benefit duration extends from 6 to 4812-60 months depending on the executive’s age. Mr. McIntosh has elected to pay additional premiums to increase his disability coverage to 75% of base salary. Messrs. Fischer and SlaterAll NEOs have elected the 60% level of coverage.

Executive Severance Plans
Executive Severance Plans. We have two Executive Severance Plans, both of which cover any officer of Olin who is subject to the reporting rules under Section 16 of the Exchange Act, including all our NEOs. The Olin Corporation Severance Plan for Section 16(b) Officers (Severance Plan) and the Olin Corporation Change in Control Severance Plan for Section 16(b) Officers (CIC Severance Plan) were adopted on December 12, 2018, in each case effective January 27, 2019. We refer to the Severance Plan and CIC Severance Plan as the Executive Severance Plans.

Proxy Statement Table of Contents
The Severance Plan provides payments and benefits to the NEOs and other covered executives in the event of certain qualifying terminations of their employment of either Mr. Dawson or Mr. Varilek terminates(other than in connection with a disability, he wouldchange in control of Olin) and the CIC Severance Plan provides payments and benefits to the covered executives in the event of certain qualifying terminations of their employment following a change in control of Olin. In adopting the Executive Severance Plans, it was our intention to provide security to our senior executives in the event of a loss of employment generally consistent with the arrangements provided by our peer companies.
Under the Severance Plan, if the executive’s employment is terminated by Olin without “cause” (other than in connection with a change in control of Olin), the executive will receive, disabilityin lieu of severance benefits under any other Olin severance plans or programs:
(1) an amount equal to 50%the sum of (i) the executive’s annual base salary untiland (ii) the executive’s target annual cash incentive opportunity for the year of termination, payable in twelve equal monthly installments;
(2) if the termination occurs in the last three quarters of the year, a pro-rated annual cash incentive payment for the year of termination based on Olin’s actual performance and payable at such time such incentive payments are payable to other employees of Olin;
(3) the continuation of medical, dental and life insurance benefits for the executive and his or her dependents for a period of twelve months at active employee rates under the applicable Olin plans or programs; and
(4) outplacement services for a period of up to twelve months.
Payments and benefits under the CIC Severance Plan are “double trigger”, which means they are paid only if (i) there is no longer disabled, electsa change in control of Olin and (ii) the executive’s employment is terminated by Olin without “cause” or the executive resigns for “good reason,” in either case, upon or within two years following the change in control. If this occurs, the executive will receive, in lieu of severance benefits under any other Olin severance plans or programs:
(1) an amount equal to take early retirement benefits or reaches age 65 (excepttwo times (or three times in the case of an employee who is over age 60 atMr. Fischer) the timesum of (i) the disability occurs).

Such severance payments and benefits under the Executive Severance and Executive Change in Control Agreements


CIC Agreements in effect until January 26, 2019.  We have executive change in control agreements withPlans are not available if the NEOs and five other executive officers. We referexecutive’s employment is terminated for “cause” by Olin, or terminates due to all of these agreementsdeath or “disability”. Except as CIC agreements, and they are identical, except that (i) the CIC agreements for Mr. Slater and seven other executives provide for payments upon a qualifying termination after a change in control at a lower

level than the other CIC agreements and (ii) the CIC agreements with Messrs. Dawson, Varilek and one other executive who executed Retention Agreements upon joining Olin from Dow (such agreements discussed below) provide for paymentsprovided under the CIC agreementsSeverance Plan for resignations due to be reduced“good reason,” an executive is not eligible for severance payments and benefits due to voluntary termination of employment by payments under the Retention Agreements.

All of the CIC agreements:

·

require a double trigger (change in control and termination or constructive termination) for early vesting of stock options and restricted stock awards, unless the acquirer fails to assume or replace those awards;

·

eliminate allgross-up for golden parachute excise taxes, substituting a “best netafter-tax” payment approach that reduces payments and benefits to the executive if the reduction would result in the executive receiving higher payments and benefits on a netafter-tax basis;

·

condition receipt of severance and other termination benefits on a release of claims by the executive;

·

contain restrictive covenants that prohibit (i) solicitation and hiring of our employees, (ii) disclosure of certain information relating to our customers and (iii) disparaging us or our business; and

·

include a provision to allow our board to determine that certain transactions, such as the Acquisition, would not constitute a change in control for purposes of these agreements, a right our board exercised in connection with the Acquisition.

In January 2014, we also amended theexecutive.

The provisions of our equity plans to (i)similarly require a double trigger“double trigger” (change in control and termination without “cause” or for “good reason” within two years of the change in control) for early vesting of all equity awards, (otherother than performance shares and awards the acquirer fails to assume or replace and performance shares), (ii) eliminate excise taxgross-ups and (iii) conform the definition of change in control to the definition in the CIC agreements, including the ability of our board to determine that certain transactions, such as the Acquisition, would not constitute a change in control for purposes of these plans, a right our board exercised in connection with the Acquisition.

The current term of the CIC agreements is scheduled to expire on January 26, 2019, and we provided notice that the term will not be extended. The CIC agreements contain an extensive definition of “change in control,” but generally a change in control occurs if:

(1)

a person or entity acquires beneficial ownership (as defined in the Exchange Act) of 20% or more of our common stockunless (a) the acquiring party is Olin, our subsidiaries or our benefit plans, an underwriter holding the shares temporarily for an offering, or a group that includes the executive who is a party to the CIC agreement or an entity that such executive controls, (b) the percentage increase occurs solely because the total number of shares outstanding is reduced by Olin repurchasing its stock or (c) the acquisition is directly from Olin;

(2)

a majority of our board members change (other than new members elected or nominated by at least 2/3 of the then-current board, unless such new member became a director pursuant to an actual or threatened proxy contest or similar dispute);

(3)

we (or any of our subsidiaries) sell all or substantially all assets, or merge or engage in a similar transaction, unless,immediately following such transaction, (a) our shareholders own a majority of the voting interest of Olin or its successor (in approximately the same ratios as before the transaction) and (b) neither of the events described in items (1) or (2) above has occurred for Olin or its successor; provided that a transaction that would

otherwise constitute a change in control under this item (3) will not be considered a change in control if: (i) at least a majority of our board members immediately before the transaction remain as board members after the transaction, (ii) at least 75% of our executive officers immediately before the transaction remain as executive officers after the transaction, and our board members at the time of approval of the transaction determine in good faith that such executive officers are expected to remain as executive officers for a significant period after the transaction, and (iii) 2/3 of such board members determine that the transaction shall not be deemed to be a change in control; or

(4)

our shareholders approve a plan of complete liquidation or dissolution of Olin.

In connection with the Acquisition, which would otherwise have satisfied the definition of change in control, our board exercised its right under item (3) above to determine that the Acquisition was not a change in control for purposes of the CIC agreements and the equity plans.

If, during the three years after a change in control (or in anticipation of a change in control) the executive’s employment is terminated without cause or for good reason, as defined in the CIC agreements, the executive will receive:

·

a lump sum cash severance payment of three times (for Messrs. Fischer and McIntosh) or two times (for Mr. Slater and the seven other executives), (i) the executive’s base salary plus (ii) the higher of the average annual SMICP payment received by the executive for the last three calendar years or the executive’s target SMICP bonus for the year of termination;

·

36 months (24 months for Mr. Slater and the seven other executives) of retirement plan contributions under our defined contribution plans, based on the executive’s severance payment;

·

36 months (24 months for Mr. Slater and the seven other executives) of coverage under our medical, dental and life insurance plans, followed by coverage pursuant to COBRA (and, if eligibility requirements are met, participation in our post-retirement medical and dental plans until age 65 on the same basis as similarly situated employees of Olin);

·

if termination of employment occurs after the first calendar quarter of any year, the executive’spro-rated target SMICP or MICP bonus for the year of termination; and

·

12 months of outplacement services.

Payments under the first three items above are prorated if the executive is within 36 months (24 months for Mr. Slater and the seven other executives) of any mandatory retirement age applicable to him or her, based on the remaining number of days until such age.

To receive these benefits the executive must execute a waiver and release of claims against Olin and its affiliates within a specified period after termination of employment. In addition, if employment is terminated without cause or for good reason during the three-year period after a change in control, the executive would be subject to restrictive covenants until the earlier of one year after termination or any mandatory retirement age applicable to that executive. The executive, regardless of the circumstances of termination, would also be prohibited from disclosing our trade secrets and other confidential information.

All payments madeand other benefits under the Executive Severance Plans are subject to the executive’s execution and non-revocation of, and continued compliance with, a separation release agreement. The separation release agreement includes a general release of all claims against Olin and the executive’s compliance with restrictive covenants provided under the Executive Severance Plans, including ongoing non-disparagement requirements with respect to Olin and certain non-competition and non-solicitation covenants during the executive’s severance period. The executive, regardless of the circumstances of the executive’s termination of employment, would also be prohibited from disclosing our trade secrets and other confidential information.

tax and any applicable federal, state and local taxes. The Executive Agreements. In addition to the CIC agreements, Messrs. FischerSeverance Plans and McIntosh and one other executive currently have executive severance agreements (executive agreements). These agreements extend until January 26, 2019, and we provided notice that the term willour equity plans do not be extended. An additional three executives have executed retention agreements (described below), which contain severance benefits different from, and in lieu of, the benefits provided in the executive agreements.

Under the executive agreements if the executive’s employment is terminated (in anon-change in control event) by Olin without cause, the executive will receive, in lieu of severance benefits underprovide for any other Olin severance plans or programs:

(1)

cash installment payments (which we refer to as the executive severance amount) equal to (a) twelve months salary plus (b) a percentage (calculated as the executive’s target bonus for the prior year divided by the executive’s salary in effect at termination) of base salary;

(2)

12 months of retirement contributions to all Olin defined contribution plans based on the amount of the cash installment payments (the executive will be treated as if he or she had remained employed for service purposes for 12 months after the termination);

(3)

12 months of medical, dental and life insurance coverage for the executive and dependents; and

(4)

the same outplacement services and prorated annual incentive compensation award provided under the CIC agreement.

Payments under the items above are prorated if the executive is within 12 months of any mandatory retirement age applicable to him or her, based on the remaining number of days until such age.

The executive must sign a waiver and general release of claims and agree toone-year noncompetition andnon-solicitation covenants to receive any severance payments and other benefits. Such severance payments and other benefits under the executive agreements are not available if the executive is terminated for cause, defined as any willful misconduct or willful breaches of the executive’s duties.

If, in connection with the sale or transfer of an Olin business or assets to a third party or to a joint venture, the executive becomes an employee of the buyer or joint venture, the executive agreement continues to applyexcise tax gross-up benefit to any termination from the new employment for 12 months. Payments by Olin are reduced for any cash severance or similar benefits from such buyer or joint venture.

Retention Agreements
. Messrs. Dawson and Varilek and one other executive who joined Olin from Dow in connection with the Acquisition hold Executive Retention Agreements (Retention Agreements) that extend until October 5, 2018. The Retention Agreements:

·

set the executive’s minimum base salary as the salary with Dow immediately prior to the Acquisition;

Treatment of Equity Awards Under Plans

·

provide for performance-based annual cash incentives with a target value no less than that provided to the executive by Dow immediately prior to the Acquisition (with a maximum bonus up to 200% of that target value);

·

provide for eligibility to receive annual equity incentive awards with an aggregate grant date fair value that is no less than the aggregate grant date fair value of equity-based compensation provided to the executive by Dow immediately prior to the Acquisition;

·

provide for a 2016 cash or equity-based award equivalent to the grant date fair value of any equity or equity-based compensation forfeited by the executive as a result of terminating employment with Dow, made in 2016 and reflected in the Summary Compensation Table for Messrs. Dawson and Varilek;

·

award cash retention bonus payments on October 5, 2017, and October 5, 2018, with a value equal to 75% of the executive’s salary and annual cash incentives as of each retention date;

·

make each executive eligible for benefits with a value substantially comparable to what the executive received at Dow immediately prior to the Acquisition; and

·

contain restrictive covenants that prohibit (i) competing with Olin, (ii) disclosure of confidential information, and (iii) disparaging us or our business.

Under the Retention Agreements, if the executive’s employment is terminated (in anon-change in control event) by Olin without cause or by the executive for “good reason,” the executive will receive:

(1)

cash severance and continued welfare benefits equal to the greater of what the executive would have received from Dow and what the executive is eligible to receive under Olin’s applicable severance plan;

(2)

if the termination occurs during or after the second calendar quarter, a prorated performance-based annual cash incentive for that calendar year based on the average payout for all participants in the cash incentive plan;

(3)

any retention bonus payments owed to the executive; and

(4)

any accrued and unused vacation or any other amounts or benefits required to be paid or that the executive is eligible to receive.

As a condition to receiving these termination benefits, the executive must execute a complete release of claims in favor of Olin, and comply with certain restrictive covenants for one year after termination. These benefits are in lieu of severance benefits under any other Olin severance plans or programs and are not awarded if the executive is terminated for cause. The Retention Agreements define cause in generally the same manner as the executive agreements, but include unsatisfactory performance, dishonesty, unethical conduct, insubordination, or violation of company rules, in the definition. In the event of a termination following a change in control that entitles the executive to severance, any severance payments will be reduced by the value of any accelerated retention bonus payments the executive receives.

Treatment of Equity Awards Under Plans


Retirement.When an employee retires:

·

vested stock options may be exercised for the remaining option term;

·

vested but unpaid performance shares will be paid as specified in the performance share program; and

·

the retired employee receives a pro rata payout in cash of any unvested performance share award at such time it would otherwise be paid.

vested stock options may be exercised for the remaining option term;
vested but unpaid performance shares will be paid as specified in the performance share program; and
the retired employee receives a pro rata payout in cash of any unvested performance share award at such time it would otherwise be paid.
The committee has discretion to waive vesting periods for restricted stock and restricted stock units.

Change in ControlControl. .As noted above, our various equity plans provide that options and restricted stock awards vest upon a change in control (as defined in the CIC agreements)Executive Severance Plans) only if there is also a termination of employment or constructive termination, or the acquiring company fails to assume these awards or substitute equivalent awards. Outstanding performance shares vest and are paid upon a change in control. The plans do not include excise taxgross-up provisions.

·

a person or entity acquires control of 20% or more of our common stock;

a majority of our board members change in atwo-year period (other than new members nominated by at least 2/3 of the then-current board);

·

all or substantially all of our business is sold through a merger or other transaction unless Olin is the surviving corporation or our shareholders own a majority of the voting interest of the new company; or

·

our shareholders approve a sale of all or substantially all of our assets or the dissolution of Olin.

our shareholders approve a sale of all or substantially all of our assets or the dissolution of Olin.
Supplemental Plan and Senior PlanPlan.. In the event of a change in control (defined in a manner compliant with Code Section 409A), we must pay a cash amount sufficient to purchase an annuity that provides the monthly after tax benefit the employee would have received under the Supplemental Plan and the Senior Plan. Those payments would be based on benefits accrued as of the change in control. Benefits were frozen at the end of 2007, although continued employment counts toward years of service for vesting and early retirement eligibility. As described above, as a result of the Acquisition, payments of amounts accrued through October 5, 2015, were made under these two plans in 2015.

PAY RATIO DISCLOSURE

As required by applicable law and SEC regulation, we calculated a reasonable estimate of the ratio of the annual total compensation of John E. Fischer, our CEO, compared to that of our median employee in 2017.

2019.

Based on the information described below, for 2017,
Based on the information described below, for 2019, the ratio of the annual total compensation of our CEO to the median of the annual total compensation of all employees was 66.77 to 1.
We used the same median employee for the pay ratio in 2017, 2018 and 2019. There was no significant change in our employee population or in the median of the annual totalemployee’s compensation of all employees was 91.68 to 1.

arrangement or other material change during those years that would significantly affect our pay ratio calculation. We identified our median employee for the 2017 pay ratio analysis using the methodology and the material assumptions, adjustments, and estimates described below.

Employee Population and Compensation.As of December 31, 2017, our global employee population consisted of 6,526 individuals working at Olin and its consolidated subsidiaries. This includes 5,536 U.S. employees. At the end of 2019, our global employee population consisted of 6,615 individuals, including 5,341 U.S. employees.

Given the geographical distribution of our employee population, we use a variety of pay elements to structure the compensation arrangements of our employees.

·

Base salary and overtime pay—the fixed portion of compensation, paid without regard to financial or operational performance.

·

Annual cash bonus/variable compensation plans—in which approximately 70% of our full-time employees globally participate, and discretionary annual bonuses—for which 60% of the hourly employees in our manufacturing organizations in North America are eligible.

·

Other benefit programs, such as health insurance and retirement plan contributions, depending on the practices and laws of the country of employment, and for certain employees, equity awards.

Other benefit programs, such as health insurance and retirement plan contributions, depending on the practices and laws of the country of employment, and for certain employees, equity awards.
Adjustment and Assumptions. WeIn determining the median employee in 2017, we applied the allowed “de minimis” exception to exclude 325 employees in the following countries: China (130); Italy (48); South Korea (36); Switzerland (33); Netherlands (23); Japan (11); United Arab Emirates (8); Hong Kong (6); Taiwan (5); Russia (4); Singapore (3); Thailand (4); India (2); Denmark (1); Poland (1); Turkey (1); South Africa (1); United Kingdom (1); and Mexico (1). If we excluded any employees from a country using this de minimis exception, all employees from that country were excluded.

We selected gross earnings (unreduced by anypre-tax medical or other benefits in the U.S.) as the appropriate measure of compensation and applied the same measure for employees innon-U.S. countries. This approach allowed us to include all elements of compensation while simplifying the process of gathering the relevant information. It also allowed us to reasonably compare compensation for North American employees and that of employees in multiple international locations. We obtained the information for ournon-North American-based employees from information maintained by a third party payroll processing provider in each country.

Proxy Statement Table of Contents

We considered gross earnings for all of our employees (other than thosenon-U.S. employees excluded under the “de minimis” exemption described above), during the12-month period ended December 31, 2017—2019—our fiscal year. We did not makecost-of-living adjustments and did not annualize compensation of employees hired during 2017.

2019.

In calculating employee compensation ofnon-U.S. employees, we averaged themonth-end exchange rates for each month in 20172019 and applied this average exchange rate to the relevant foreign currencies to convert compensation to U.S. dollars.

Median Employee.Using the methodology described, above, we determined that the “median employee” for the 12-month period ended December 31, 2017, was a full-time, salariednon-exempt lab technician in our Chlor Alkali Products and Vinyls division, working in the U.S., with gross earnings (wages, overtime pay and variable compensation) for the12-month period ended December 31, 2017 of approximately $78,838.

We determined the annual total compensation of this “median employee” by calculating the elements of 2017 compensation in accordance with the requirements that apply to the Summary Compensation Table for our NEOs on page 45. This resulted in annual total compensation of $84,855. As noted above, we used 2017 gross earnings to identify this employee as our median employee, which include the bonus for 2016 performance paid in 2017. The

As noted above, we are using the same median employee for the 2019 pay ratio calculation.
For the 12-month period ended December 31, 2019, the median employee had gross earnings (wages, overtime pay and variable compensation) of approximately $93,907.

compensation for our directors is governed by the Directors Plan. The annual stock grant, retainer stock grant and cash retainer are paid for the12-month period running from May 1 to April 30, with payments made on March 1 or the first day in March on which the NYSE is open for trading.

Under the Directors Plan, directors may choose to receive common stock instead of cash for any portion of their compensation. Directors may also elect to defer payments (cash or stock). We credit their deferred accounts with quarterly interest (on the cash portion) and with dividend equivalents (on the phantom stock portion). Phantom stock units are paid out in shares of our common stock or, at the director’s election, in cash. We also pay the balance of any deferred account to the director if there is a change in control—generally if:

·

a person or group acquires 40% or more of our assets, 30% or more of our stock, or a majority of the market value or voting power of our stock, or

·

a majority of our board members are not endorsed by the directors in office at the time of election.

We have stock ownership guidelines for ournon-employee directors where each such director is expected to own shares of our common stock with a market value of at least five times the amount of the annual retainer, within five years after the director joins our board. Eachnon-employee director met these guidelines and is in compliance with these guidelines as of the date of this Proxy Statement.

ITEM 2—PROPOSAL TO APPROVE THE

OLIN CORPORATION 2018 LONG TERM INCENTIVE PLAN

The board of directors proposes that the shareholders approve the Olin Corporation 2018 Long Term Incentive Plan, or 2018 LTIP, as adopted by the board on February 16, 2018.

The 2018 LTIP, if approved, will provide for the issuance of 9,000,000 shares, plus any shares that were subject to outstanding awards to employees under our other equity plans that are cancelled, terminate, are unearned, expire, are forfeited, lapse for any reason or are settled in cash without the delivery of shares. If the 2018 LTIP is approved, no additional awards will be granted under our other equity incentive plans, except the Directors Plan.

The principal features of the 2018 LTIP are summarized below. The summary is not intended to be a complete description of the 2018 LTIP, and you should review the entire 2018 LTIP, a copy of which is included in this Proxy Statement as Appendix A.

General Nature and Purpose


The principal purposes of the 2018 LTIP are to (a) attract and retain employees, (b) provide competitive compensation packages to participants, (c) motivate participants to achieve long-range goals and (d) further align participants’ interests with those of Olin’s shareholders.

Under the 2018 LTIP, shares may be issued upon exercise or granting of options, stock appreciation rights (SARs), restricted stock, restricted stock units, performance shares and other stock-based awards (collectively, “awards”).

The LTIP provides that any employee of Olin or a subsidiary is eligible to participate in the plan. The number of participants in our equity plans has ranged between 190 and 240 in the past two years. Awards are made to officers and certain other senior-level employees annually as part of their overall compensation package. In addition,one-time special awards are made to other employees to recognize specific performance.

The board considered a number of factors in determining the number of shares of Olin common stock to be included in the 2018 LTIP for approval, including:

·

the number of participants;

·C. Robert Bunch, Chairman
Heidi S. Alderman

William H. Weideman
Carol A. Williams
February 18, 2020

the historic burn rate associated with Olin equity compensation;

·

the potential dilutive impact of the issuance of shares under the 2018 LTIP on our stockholders; and

·

projections regarding future share usage.

Burn rate measures our usage of shares for our stock plans as a percentage of our outstanding stock. For 2017, 2016, and 2015, our burn rate was 0.88%, 0.98% and 0.83%, respectively. The rates were calculated by dividing the number of shares subject to awards granted during the fiscal year net of forfeitures and cancellations by the weighted average number of shares outstanding during the fiscal year. We have been advised by independent consultants that our average annual burn rate of 0.90% over this three-year period is considered reasonable by most institutional stockholders.

The board believes that the historic and proposed levels of dilution and burn rates are reasonable and in line with those of peer companies.

Administration


The board designated the compensation committee to administer the 2018 LTIP. The committee has full power to interpret the 2018 LTIP, including to determine eligibility for awards, and to adopt rules, forms and guidelines under the 2018 LTIP. Each member of the committee must be (i) a“non-employee director” for purposes of Rule16b-3 under the Exchange Act (Rule16b-3) and (ii) “independent” under the NYSE listing criteria. The full board also may elect to take any action under the 2018 LTIP that would otherwise be the responsibility of the compensation committee. The committee may delegate partial or full authority to one or more members of Olin’s management under the 2018 LTIP with respect to eligible employees who are not “officers” for purposes of Section 16(b) of the Exchange Act.

Subject to the terms and conditions of the 2018 LTIP, the committee has the authority to select the employees to whom awards are to be made, to determine the number of shares to be subject to awards and the terms and conditions of awards, and to make all other determinations and to take other actions necessary or advisable for the administration of the 2018 LTIP (other than to reprice outstanding options). The committee may at any time suspend or terminate the 2018 LTIP. Shareholder approval is required to reprice options. Shareholder approval is also required to increase the maximum number of shares subject to awards or other award limits or to reduce the minimum option exercise price, except that the committee is allowed to make appropriate proportionate adjustments for stock dividends, stock splits or similar events as allowed in Section 4(b) of the 2018 LTIP.

Eligibility


Awards under the 2018 LTIP may be granted to employees of Olin (or any current or future subsidiaries) selected by the committee for participation in the 2018 LTIP.

Awards


The 2018 LTIP provides that the committee will specify the type, terms and conditions of the award. Each award may be set forth in a separate agreement with the person receiving the award.

The 2018 LTIP provides that:

·

awards may be granted under the 2018 LTIP for up to 9,000,000 shares of Olin common stock, plus any shares subject to outstanding awards to employees under any other equity plan to the extent such awards expire, or are cancelled, forfeited or otherwise terminated without the issuance of shares after the effective date for the 2018 LTIP;

·

no more than 5,000,000 shares may be subject to grants of Incentive Stock Options (ISO);

·

no more than 2,000,000 shares may be subject to full value awards (restricted stock, restricted stock units, performance shares and other full value stock-based awards);

·

no more than 750,000 shares may be subject to options granted to any one individual in a calendar year;

·

no more than 750,000 shares may be subject to SARs granted to any one individual in a calendar year;

·

no more than 750,000 shares may be subject to restricted stock and restricted stock units granted to any one individual in a calendar year;

·

no more than 750,000 shares may be subject to performance shares granted to any one individual in a calendar year; and

·

no more than 750,000 shares may be subject to other stock-based awards granted to any one individual in a calendar year.

Shares exchanged or withheld to pay the purchase or exercise price of an award (including shares withheld to satisfy the exercise price of a SAR settled in stock), or to satisfy tax withholding obligations, count against the numerical limits.

The 2018 LTIP allows for grants of options, or the right to purchase Olin common stock at a specified price. Options may be nonqualified stock options (NQSOs) or ISOs. Total ISO awards are limited to 5,000,000 shares. No option exercise price may be less than the fair market value on the date of grant, which, unless the committee determines otherwise, is the closing price of Olin common stock on such date. The closing price of Olin common stock as of February 16, 2018 was $32.67. An option will become exercisable (at the discretion of the committee) in one or more installments on or after the grant date, subject to the participant’s continued employment with Olin.

ISOs will be designed to comply with certain restrictions contained in the Code. ISOs may be subsequently modified to disqualify them from treatment as ISOs. In the case of an ISO granted to an individual who owns (or is deemed to own) at least 10% of the total combined voting power of all classes of stock of Olin, the exercise price must be at least 110% of the fair market value of a share of Olin common stock on the date of grant, and the ISO must expire no later than the fifth anniversary of the date of its grant.

Restricted stock refers to stock that is subject to risk of forfeiture or other restrictions as the committee determines. Such restrictions will lapse under such circumstances as the committee may determine, including upon the achievement of performance criteria. In general, restricted stock may not be sold, or otherwise transferred or hypothecated, until the restrictions (if any) are removed or expire. Recipients of restricted stock may have voting rights and receive dividends paid with respect to such stock prior to the time when the restrictions lapse, as determined by the committee.

A restricted stock unit entitles the holder to receive shares of Olin common stock or cash at the end of a specified deferral period but does not entitle the holder to any voting rights. If the committee determines, holders of unvested restricted stock units may receive dividends or dividend equivalent payments.

The committee may issue shares of restricted stock or restricted stock units up to an aggregate 5% of the total number of shares available for issuance under this plan without any minimum vesting period. Grants of restricted stock and restricted stock units above that level must include a minimumone-year vesting period for performance-based grants and a minimum three-year vesting period for grants without any performance-based component.

Performance shares provide for future issuance of shares to the recipient upon the attainment of corporate performance goals established by the committee over specified performance periods. Prior to payment of performance shares, the committee will certify that the performance objectives were satisfied. Performance objectives may vary from individual to individual and will be based upon one or more performance criteria the committee may deem appropriate, including the criteria described above.

SARs may be granted in connection with stock options or separately, and are payable in cash. The term of a SAR may not exceed ten years. A SAR entitles the holder to receive, with respect to each share subject to the SAR, an amount equal to the excess of the fair market value of one share of Olin common stock on the date of exercise over the exercise price of the SAR set by the committee as of the date of grant. There are no restrictions specified in the 2018 LTIP on the amount of gain realizable from the exercise of SARs, although restrictions may be imposed by the committee.

Dividend equivalents represent the value of any dividends per share paid by Olin, calculated with reference to the number of shares covered by the awards held by the participant. This value is converted into cash or additional shares of Olin common stock, as determined by the committee. Payment may be made concurrently with actual dividend payments or may be deferred, at the election of the committee.

The committee may make other stock-based awards in such amounts and subject to such terms and conditions as the committee shall determine.

General


Method of Exercise. To exercise an option, the optionee must deliver to Olin a notice of exercise and full payment for the shares. The option price may be paid in cash, or by tendering shares of Olin common stock already issued or issuable upon exercise of the option or by any other form of payment, which is approved by the committee and is consistent with the 2018 LTIP and applicable law, or by any combination of the above.

Termination of Employment. Awards terminate upon termination of the participant’s employment by Olin for cause or by the employee without Olin’s written consent. Vested options held

at the time an optionee’s employment terminates for any other reason (excluding retirement) may be exercised for three months after termination, or such longer period as the committee provides. Vested options held at the time an optionee’s employment terminates due to retirement may be exercised at any time until the expiration date of the option, or such shorter period as the committee provides at the time of the termination. In no event, however, can an option be extended beyond the expiration date.

Non-Compete. If a participant renders service to a competitor of Olin, or discloses confidential information without Olin’s consent, or violates other terms of the 2018 LTIP, generally the committee may terminate any unvested, unpaid or deferred awards held by the participant, or may require the participant to forfeit benefits received under the 2018 LTIP within the six months prior to such action.

Non-Transferability. Awards may be transferred only by will or by the laws of descent and distribution, and during a participant’s lifetime are exercisable only by the participant. However, the committee may in its discretion permit transfers by gift to a member of the holder’s family members or related entities or pursuant to certain domestic relations orders.

Change in Control. In the event of a Change in Control of Olin (except for performance shares, which will become immediately and fully vested), the vesting of awards will only be accelerated if:

·

the acquiring company does not continue the restricted stock units (or a comparable award) after the Change in Control; or

·

the recipient’s employment is terminated (or in certain cases, constructively terminated) upon or following the Change in Control.

A “Change in Control” occurs if:

·

the incumbent directors (or their successors approved by at leasttwo-thirds of the incumbent directors) cease to constitute at least a majority of the members of the board (except directors initially added to the board as a result of an actual or threatened election contest);

·

a person or group of persons other than Olin, a subsidiary, employee benefit plan (or related trust) of Olin or a subsidiary, the participant or any group including the participant, or an underwriter on a temporary basis, becomes the beneficial owner (as that term is defined under Rule13d-3 of the Exchange Act), of 20% or more of Olin’s then-outstanding voting stock;

·

Olin or a subsidiary consummates a merger or similar transaction or sells all or substantially all of its assets to an unaffiliated entity, unless immediately following such transaction: (1) more than 50% of the total voting power of the surviving entity or of the acquiring entity is represented by Olin common stock or securities into which such shares were converted, (2) no person (other than an employee benefit plan sponsored or maintained by the surviving entity or the acquiring entity) becomes the beneficial owner of 20% or more of the total voting power and (3) at least a majority of the members of the board (or similar body) of the surviving entity or the acquiring entity were incumbent directors of Olin’s board at the time Olin’s board approved the initial agreement for such transaction; or

·

Olin’s shareholders approve a plan of complete liquidation or dissolution of Olin.

ERISA. The 2018 LTIP is neither a qualified pension, profit sharing or stock bonus plan under Code Section 401(a) nor an “employee benefit plan” subject to the provisions of the Employee Retirement Income Security Act of 1974, as amended.

Adjustments Upon Change in Capitalization. If the outstanding shares of Olin common stock are changed into or exchanged for a different number or kind of shares of Olin or other securities of Olin by reason of merger, consolidation, recapitalization, stock split, stock dividend, combination or exchange of shares,split-up,split-off,spin-off or other similar change in capitalization or any distribution to shareholders other than cash dividends, the committee will make an appropriate and equitable adjustment in the number, kind and prices of shares as to which all outstanding awards will be awarded, including adjustments to the limitations on the maximum number and kind of shares subject to the award limits.

Shares Available for Awards. Subject to adjustment as provided in the 2018 LTIP, the aggregate number of shares of our common stock reserved and available for issuance for awards granted under the 2018 LTIP is the sum of (i) 9,000,000 shares not previously authorized for issuance under any other plan, plus (ii) any shares currently subject to any outstanding award under the prior equity plans for employees as of the effective date of the 2018 LTIP, to the extent forfeited. For details regarding the shares subject to outstanding equity awards, see the table entitled “Equity Compensation Plan Information” on page 77. Shares subject to awards under the existing employee equity plans or the 2018 LTIP that are cancelled, forfeited or otherwise terminated, or that by their terms are settled entirely in cash instead of shares, will be added back to the shares available under the 2018 LTIP. Shares exchanged or withheld to pay the purchase or exercise price of an award (including shares withheld to satisfy the exercise price of a SAR settled in stock) or to satisfy tax withholding obligations count against the numerical limits. Of these shares, a maximum of 5,000,000 shares may be subject to grants of Incentive Stock Options (ISOs) and 2,000,000 shares may be “full value awards” (restricted stock, restricted stock units, performance shares and other full value stock-based awards).

Changes from 2016 LTIP. The 2018 LTIP is modeled after our current 2016 LTIP, approved by shareholders at the 2016 annual meeting. The primary substantive change from the 2016 LTIP is an increase in the number of shares subject to the plan from 6,000,000 to 9,000,000 shares, coupled with a prohibition on any additional awards under our other equity plans for employees. Any shares subject to outstanding awards under any of our other equity plans for employees that may expire, be cancelled, forfeited or otherwise terminated without the issuance of shares after the date the 2018 LTIP is approved by shareholders will be added to the 2018 LTIP.

The 2018 LTIP also includes appropriate increases in the various caps on different types of awards and if the 2018 LTIP is approved, no additional awards will be granted under our other equity plans (our 2000, 2003, 2006, 2009, 2014 and 2016 Long Term Incentive Plans), except for the Directors Plan.

Amendment. The compensation committee generally may amend the 2018 LTIP, except for amendments that would increase the total number of shares available for awards or for any category of awards, reduce the minimum option exercise price, or permit repricing of options (other than such amendments made pursuant to permitted adjustments under the 2018 LTIP).

Benefits Under 2018 LTIP


No awards have been granted under the 2018 LTIP, so that benefits accruing pursuant to the 2018 LTIP are not presently determinable.

Federal Income Tax Consequences


We believe that under present law, the following discussion summarizes the U.S. federal income tax consequences generally arising with respect to awards under the 2018 LTIP.

Stock Options. The grant of a NQSO is not a taxable event either for the optionee or for Olin. Upon exercise of a NQSO, the optionee will recognize ordinary income in an amount equal to the excess of the fair market value of the shares of Olin common stock acquired upon exercise, determined at the date of exercise, over the exercise price of such option. Olin will be entitled to a business expense deduction equal to such amount, subject to the limitations imposed by Code Section 162(m). Generally, Code Section 162(m) restricts deductibility by Olin of compensation above $1 million paid to the CEO, the CFO and the three highly paid officers (other than the CEO and CFO), and any person who was a CEO, CFO, or one of the other three highest paid officers in any year after 2016.

An optionee recognizes no taxable income upon the grant or exercise of an ISO, although payment of the option price with shares of Olin common stock may result in taxable income on the transfer of the shares. The payment in shares will not affect the favorable tax treatment of the Olin common stock received as a result of exercising the option. If an optionee meets the various holding period requirements, any gain or loss on the subsequent disposition of such Olin common stock will be taxed to the optionee as long-term capital gain or loss, and Olin will not be entitled to a deduction. To the extent that an optionee recognizes ordinary income by reason of failing to meet those requirements, Olin will be entitled to a corresponding business expense deduction, subject to the limit imposed by Code Section 162(m).

Restricted Stock and Restricted Stock Units. A holder of restricted stock generally will recognize ordinary income in an amount equal to the fair market value of the Olin common stock upon lapse of the restrictions. A holder of restricted stock units generally will recognize ordinary income in an amount equal to the fair market value of the Olin common stock upon issuance of the shares (or upon receipt of the cash payment, in an amount equal to the cash payment, if the restricted stock units are settled in cash). Subject to the limit imposed by Code Section 162(m), Olin is entitled to a business expense deduction that corresponds to the amount of ordinary income recognized by the holder.

SARs. Generally, the holder of a SAR recognizes no income upon the grant of a SAR. Upon exercise, the holder will recognize as ordinary income the excess of the value of the SAR on the date of exercise over the value as of the date of grant. Olin is entitled to a business expense deduction that corresponds to the amount of ordinary income recognized by the holder, subject to the limit imposed by Code Section 162(m).

Dividend Equivalents and Deferred Payments of Restricted Stock. In general, recipients of dividend equivalents and deferred payments of restricted stock are taxable upon receipt. Subject to the limit imposed by Code Section 162(m), Olin is entitled to a business expense deduction that corresponds to the amount of ordinary income recognized by the recipient.

Payment of Withholding Taxes


Olin may withhold, or require a participant to remit to Olin, an amount sufficient to satisfy any federal, state or local withholding tax requirements associated with awards under the 2018 LTIP. Recipients of awards may elect, subject to the approval of the committee, to satisfy the withholding requirement by having Olin withhold shares.

Vote Required for Approval


The affirmative vote of the holders of a majority of the votes cast is required to approve this proposal. If you hold your shares through a broker and you do not instruct the broker on how to vote on

this proposal, your broker will not have authority to vote your shares. Under applicable NYSE rules, abstentions will be treated as votes cast on this proposal, but shares held in street name that are not voted on this proposal will not be treated as votes cast on this proposal. As a result, shares held in street name that are not voted on this proposal will have no effect on the proposal to approve the 2018 LTIP. Abstentions will have the same effect as a vote AGAINST the proposal to approve the 2018 LTIP. Signed proxies will be voted FOR approval of the proposal unless otherwise specified.

The board recommends a vote FOR approval of the 2018 Long Term Incentive Plan.

ITEM 3—2—PROPOSAL TO CONDUCT AN ADVISORY VOTE TO
APPROVE THE COMPENSATION FOR NAMED EXECUTIVE OFFICERS

Following the advisory vote on the frequency of a shareholder vote on executive compensation at last year’s annual meeting of shareholders, our board of directors decided to continue with the annual advisory vote by shareholders to approve the compensation for NEOs.

You are being asked to cast an advisory vote on approval of the compensation of our NEOs at the annual meeting. This proposal, commonly known as a“say-on-pay” “say-on-pay” proposal, is required under Section 14A of the Exchange Act. The proposal gives you the opportunity, on an advisory vote basis, to approve or not approve the compensation of the NEOs through the following resolution:

“RESOLVED, that the compensation paid to the Olin named executive officers, as disclosed pursuant to Item 402 of RegulationS-K, including the Compensation Discussion and Analysis, compensation tables and narrative disclosure, is hereby APPROVED.”

Because your vote is advisory, it will not be binding on the board and it will not directly affect or otherwise limit any existing compensation or award arrangement of any of our NEOs. Our compensation committee does intend to take into account the outcome of the vote when considering future executive compensation arrangements.

Our audit committee has a policy that all audit services by any independent registered public accounting firm and allnon-audit services performed by our independent registered public accounting firm are subject topre-approval by the audit committee at each scheduled meeting. The policy includes specific procedures for approval of such services. Excerpts from this policy follow:

Olin’s audit committee is solely responsible forpre-approving all audit services by any independent registered public accounting firm and allnon-audit services performed by Olin’s independent registered public accounting firm. The process for such approval is as follows:

·

The annual budget for all such services will be submitted to the committee for approval in the first quarter of each year. The budget submission will include details of actual expenditures for each audit andThe annual budget for all such services will be submitted to the committee for approval in the first quarter of each year. The budget submission will include details of actual expenditures for each audit and non-audit service for the prior year versus the prior year budget and estimated spending for services in the current year. The budget will also provide for certain specific services that will be pre-approved within a limited dollar range per service. These pre-approved services are also subject to an annual spending cap.

At each subsequent audit committee meeting, the budget will be updated for changes in estimated spending involving previously approved services. The budget will also be updated to include any new services identified by operations management that need to be submitted for approval.
Any services not detailed in the budget or on the list of specific services that will bepre-approved within a limited dollar range per service. Thesepre-approved services are also subject to an annual spending cap.

OLIN CORPORATION

2018 LONG TERM INCENTIVE PLAN

Section 1.Purpose.

The general purposes

ITEM 4—APPROVAL OF AMENDMENT TO AMENDED AND RESTATED ARTICLES OF INCORPORATION TO DECLASSIFY
THE BOARD OF DIRECTORS
Olin’s current Amended and Restated Articles of Incorporation (Current Articles) divide the board of directors into three classes. Each class is elected for a three-year term, with the terms staggered so that approximately one-third of the Olin Corporation 2018 Long Term Incentive Plan aredirectors stands for election each year.
The board of directors recommends amendments to (i) attractthe Current Articles (collectively, the Declassification Amendment) that would declassify the board and retain persons eligiblerequire each director nominee to participatebe elected annually for a one-year term. Under the proposed amendments, the annual election of all directors would commence at the 2021 annual meeting. Declassification would therefore result in the Plan; (ii) motivate Participants, byshortening of the existing terms of each of the directors whose terms extend beyond the 2021 annual meeting.
Many public companies have had classified boards, intended to provide continuity among directors and encourage the independence and long-term focus of directors, reasoning that directors serving longer terms are less subject to outside influence. However, classified board structures have come to be viewed as a negative governance practice due to the perception that directors elected to staggered multi-year terms are less accountable to shareholders. Director elections are the primary means for shareholders to express their views on the performance of appropriate incentives, to achieve long-range goals; (iii) provide incentive compensation opportunitiesindividual directors, and a classified board structure affords shareholders this opportunity only once every three years for each director. A declassified board of directors has become a corporate governance “best practice”.
The board of directors considered the advantages and disadvantages of the current classified structure and determined that are competitive with those of other similar companies; and (iv) further align Participants’the Declassification Amendment is in the best interests with those of other shareholders of Olin Corporation through compensation that is based on Olin’s common stock; and thereby promote the long-term financial interest of Olin and its Affiliates, including growth inshareholders.
If approved by shareholders, the valueDeclassification Amendment would become effective upon the Company receiving a Certificate of Olin’s equity and enhancement of long-term shareholder return.

Unless otherwise specified in the applicable Award Agreement or policies adopted by the Compensation Committee, upon termination of such Participant’s employment either (a) for cause, or (b) voluntarily on the part of the Participant and without the written consent of Olin or an Affiliate, any Awards held by him or her under the Plan, to the extent not exercised or paid, shall terminate immediately.

(vii)

Termination due to Retirement. 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 Option has been granted under the Plan shall be terminated due to Retirement, such Option may be exercised (to the extent of the number of shares that the Participant was entitled to purchase under such Option at the termination of employment) at any time until the expiration date of the Option; provided, however, that such exercise period may be shortened by the Committee in its discretion at the time of termination.

(viii)

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

(ix)

Disability. Unless otherwise specified in the applicable Award Agreement or policies adopted by the Compensation Committee, if a Participant to whom an Option has been granted shall become totally and permanently disabled, as that term is defined in Section 22(e)(3) of the Code (or a successor provision), and the Participant’s employment is terminated as a result, such option may be exercised by the Participant or permitted transferee within one year after the date of termination of employment, to the extent that the Option was exercisable at the time of termination of employment.

(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 SARs granted to a Participant shall become vested and exercisable no earlier than one (1) year after the grant, and in no event shall the term of a Stock Appreciation Right exceed a period of ten years from the date of its grant.

(c)

Other 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 Other Stock-Based Awards in such amounts and subject to such terms and conditions, as the Committee shall determine, provided that no such Award shall become vested and exercisable earlier than one (1) year after grant. 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)

Dividends and Dividend Equivalents. An Award (other than unvested Options, Performance Shares or Stock Appreciation Rights) may provide the Participant with the right to receive dividend payments or dividend equivalent payments with respect to Shares subject to the Award (both before and after the Shares subject to the Award are earned, vested, or acquired), which payments may be either made currently or credited to an account for the Participant, and may be settled in cash or Shares as determined by the Committee; provided, however, that no dividend payments or dividend equivalent payments shall be

provided, permitted or credited to the extent that such payments would cause a Restricted Stock Unit or Stock Appreciation Right to be subject to Code Section 409A. Any such settlements, and any such crediting of dividends or dividend equivalents or reinvestment in Shares, may be subject to such conditions, restrictions and contingencies as the Committee shall establish, including the reinvestment of such credited amounts in Share equivalents.

(iii)

Restrictions. Any such Award shall be subject to such conditions, restrictions and contingencies as the Committee may impose (including, without limitation, any limitation on the right to vote Restricted Stock or the right to receive any dividend or other right or property), which may lapse separately or in combination at such time or times, as the Committee may deem appropriate, provided that in order for a Participant to vest in Awards of Restricted Stock or Restricted Stock Units, the Participant must remain in the employ of Olin or an Affiliate for a period of not less than one (1) year after the grant of Restricted Stock or Restricted Stock Units that includes one or more performance criteria, and not less than three (3) years after the grant of Restricted Stock or Restricted Stock Units that does not include one or more performance criteria, in each case subject to Section 9 hereof and subject to relief for specified reasons as may be approved by the Committee.

(iv)

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

(d)

Forms of Payment Under Awards. Subject to the terms of the Plan and of any applicable Award Agreement, 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. Notwithstanding the foregoing, the payment of the exercise price of an Option shall be subject to the following:

(i)

Subject to the following provisions of this subsection 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 the Committee and described below, payment may be made as soon as practicable after the exercise).

(ii)

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

(iii)

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.

(e)

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.

For purposes of this provision, a transfer to an entity in exchange for an interest in that entity shall constitute a gift.

(f)

General.

(i)

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

(ii)

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

(iii)

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

(A)

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.

(B)

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

(iv)

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

(v)

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.

(vi)

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.

(vii)

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, 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.

(viii)

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

(ix)

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.

(x)

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.

(xi)

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.

(xii)

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.

(xiii)

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

(xiv)

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.

(xv)

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 othernon-paper Award Agreements, and the use of electronic, internet or othernon-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.

(xvi)

Olin Policies. All Awards shall be subject to any “clawback,” compensation recoupment or similar policy of Olin applicable to such Award, regardless of when such policy is adopted.

(g)

Agreement to Service. Each Participant receiving an Award shall, by accepting the Award, agree that he or she will, during employment, devote his or her entire time, energy and skill to the service of Olin and the promotion of its interests, subject to vacations, sick leave and other absences in accordance with the regular policies of, or other reasons satisfactory to, Olin and its Affiliates.

(h)

Exception toOne-Year Vesting and Performance Period. Notwithstanding anything in this Plan to the contrary, Awards for an aggregate number of Shares not to exceed 5% of the total number of shares available for issuance under this Plan may vest or become exercisable in less than one (1) year after the date of grant, including immediate vesting.

Section 7.Amendment and Termination.

(a)

Amendments to the Plan. The Committee may amend, suspend, discontinue or terminate the Plan, including, without limitation, any amendment, suspension, discontinuation or termination that would impair the rights of any Participant, or any other holder or beneficiary of any Award theretofore granted, without the consent of any shareholder, Participant, other holder or beneficiary of an Award, or other Person; provided, however, that, notwithstanding any other provision of the Plan or any Award Agreement, without the approval of the shareholders of Olin, no such amendment, suspension, discontinuation or termination shall be made that would:

(i)

increase the total number of Shares available for Awards under the Plan or the total number of Shares subject to one or more categories of Awards pursuant to Section 4(c), in either case except as provided in Section 4(b);

(ii)

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

(iii)

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

providedfurther that no amendment, suspension, discontinuation or termination (i) that would impair the rights of such Participant, holder or beneficiary shall be made with respect to Section 9 of the Plan after a Change in Control and (ii) may increase the amount of payment of any Award to any Participant.

(b)

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

(c)

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

(d)

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

(e)

409A Compliance. To the extent any provision of the Plan (or any Award) or action by the Board or Committee would subject any Participant to liability for interest or additional taxes under Code Section 409A(a)(1)(B), it will be deemed null and void, to the extent permitted by law and deemed advisable by the Committee. It is intended that the Plan (and any Award) will comply with 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 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 distributions 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 8.Additional Conditions to Enjoyment of Awards.

(a)

The Committee may cancel any unexpired, unpaid or deferred Awards if at any time the Participant is not in compliance with all applicable provisions of the Award Agreement, the Plan and the following conditions:

(i)

A Participant shall not render services for any Person or engage, directly or indirectly, in any business which, in the judgment of the Committee is or becomes competitive with Olin or any Affiliate, or which is or becomes otherwise prejudicial to or in conflict with the interests of Olin or any Affiliate. Such judgment shall be based on the Participant’s positions and responsibilities while employed by Olin or an Affiliate, the Participant’s post

employment responsibilities and position with the other Person or business, the extent of past, current and potential competition or conflict between Olin or an Affiliate and the other Person or business, the effect on customers, suppliers and competitors of the Participant’s assuming the post employment position, the guidelines established in any ethical or business conduct standards of Olin then in effect, and such other considerations as are deemed relevant given the applicable facts and circumstances. The Participant shall be free, however, to purchase as an investment or otherwise, stock or other securities of such Person or business so long as they are listed upon a recognized securities exchange or traded over the counter, and such investment does not represent a substantial investment to the Participant or a greater than 1% equity interest in the organization or business.

(ii)

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

(iii)

A Participant, pursuant to his or her agreement with Olin or an Affiliate, shall disclose promptly and assign to Olin or the Affiliate all right, title and interest in any invention or idea, patentable or not, made or conceived by the Participant during employment by Olin or the Affiliate, relating in any manner to the actual or anticipated business, research or development work of Olin or the Affiliate and shall do anything reasonably necessary to enable Olin or the Affiliate to secure a patent where appropriate in the United States and in foreign countries.

(b)

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

(c)

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

(d)

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

(e)

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

Section 9.Change in Control.

(a)

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

(b)

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

(i)

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

(ii)

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

Notwithstanding the foregoing sentence, unless provision is made in connection with a Change in Control for (i) assumption of such Awards or (ii) substitution of such Awards for new awards covering stock of a successor corporation or its “parent corporation” (as defined in Section 424(e) of the Code) or “subsidiary corporation” (as defined in Section 424(f) of the Code) with appropriate adjustments as to the number and kinds of shares and exercise prices (if applicable) that preserve the material terms and conditions of such Awards as in effecther resignation effective immediately prior to election of directors at the Change in Control (including, without limitation, with respect to2021 annual meeting, conditioned upon Olin’s shareholders approving the vesting schedules,Declassification Amendment and Olin receiving a Certificate of Amendment from the intrinsic valueState Corporation Commission of the AwardsCommonwealth of Virginia.
