Dear Olin Shareholder:

We cordially invite you to attend our 2008 annual meeting of shareholders.

This booklet includes the notice and proxy statement, which describes the business we will conduct at the meeting and provides information about Olin that you should consider when you vote your shares. We have not planned a communications segment or any multimedia presentations for the 2008 annual meeting.

Ms. Virginia A. Kamsky, a Class II director, decided not to stand for re-election as a Director of the Company when her term expires on April 24, 2008. Ms. Kamsky indicated that her decision related to her increased business commitments related to China. The board thanks Ms. Kamsky for her contributions and extends its best wishes in her future endeavors.

Whether or not you plan to attend, it is important that your shares are represented and voted at the annual meeting. If you do not plan to attend the annual meeting, you may vote your shares on the Internet, by telephone or by completing and returning the proxy card in the enclosed envelope. If you plan to attend the annual meeting, please bring the lower half of your proxy card to use as your admission ticket for the meeting.

At last year’s annual meeting more than 93% of our shares were represented in person or by proxy. We hope for the same high level of representation at this year’s meeting and we urge you to vote as soon as possible.

Sincerely,

Joseph D. Rupp

Chairman, President and

Chief Executive Officer

YOUR VOTE IS IMPORTANT

Each shareholder on the record date may cast one vote for each full share owned. The presence in person or by proxy of the holders of a majority of such shares constitutes a quorum. If a share is present for any purpose at the meeting, it is deemed to be present for the transaction of all business. Abstentions, withheld votes in the election of directors and shares held in street name that are voted on any matter will be included in determining the number of votes present. Shares held in street name that are not voted on any matter at the meeting will not be included in determining whether a quorum is present.

If you specifically mark the proxy card (or vote by telephone or Internet) and indicate how you want your vote to be cast regarding any matter, your directions will be followed. If you submit the proxy card but do not specifically mark it with your instructions as to how you want to vote, the proxy will be voted for the election of the directors and in favor of Item 2 listed in the proxy.

BNY Mellon Shareowner Services (BNY Mellon) tabulates the shareholder votes and provides an independent inspector of election as part of its services as our registrar and transfer agent. If you submit a proxy card marked “abstain” or “withhold” on any item, your shares will not be voted on the item so marked and your vote will not be included in determining the number of votes cast for that matter.

If you are a participant in either CEOP, you may instruct the Trustee of that CEOP how to vote shares of common stock credited to you by voting on the Internet or telephone or by indicating your instructions on your proxy card and returning it to us. The Trustees will vote shares of common stock held in the CEOP for which they do not receive voting instructions in the same manner proportionately as they vote the shares of common stock for which they do receive instructions.

How do I vote my shares held in the Automatic Dividend Reinvestment Plan?

BNY Mellon is our registrar and transfer agent and administers the Automatic Dividend Reinvestment Plan.

The terms of the other directors will continue after the annual meeting as indicated above. The board expects that all of the nominees 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 is involved in a search for one additional director. While the board has not selected an additional director at the time this proxy statement is being mailed, the board intends to continue its search and may appoint a director prior to the annual shareholders meeting in 2009. Virginia law and Olin’s Bylaws require that any director elected by the board of directors serves only until the next election of Directors by the shareholders.

CORPORATE GOVERNANCE MATTERS

How many meetings did Board members attend?

During 2007, the board held twelve meetings. As part of each board meeting, the non-executive directors met in executive session. All directors attended at least 75% of the meetings of the board and committees of the board on which they served. All of our directors attended the 2007 annual shareholders meeting. Our policy regarding directors’ attendance at the annual shareholders meeting is that they are required to attend, absent serious extenuating circumstances.

Which Board members are independent?

Our board has determined that all of its members, except Messrs. Ruggiero and Rupp, are independent in accordance with applicable New York Stock Exchange (NYSE) listing standards and applicable provisions of our Principles of Corporate Governance. In determining independence, the board confirms that a director has no relationship with Olin that violates the “bright line” independence standards under the NYSE listing standards. The board also reviews whether a director has any other material relationship with Olin, after consideration of all relevant facts and circumstances. In assessing the materiality of a director’s relationship to Olin, the board considers the issues from the director’s standpoint and from the perspective of the persons or organizations with which the director has an affiliation. The board reviews commercial, industrial, banking, consulting, legal, accounting, charitable and familial relationships.

In 2007, we sold an aggregate of approximately $1.8 million of chlor alkali products to The Lubrizol Corporation. One of our directors, Donald Bogus, serves as vice president of Lubrizol. Our board determined that Mr. Bogus had no material interest in these sales transactions because the transactions were made on our customary terms and conditions, and amounted to less than 0.4% of Lubrizol’s total sales.

In 2007, we matched charitable contributions made by several directors under our 50% matching contribution program, which is available to all employees. None of those amounts exceeded $5,000 and our board determined that such minimal charitable contribution matches do not constitute the type of relationship that could impair a director’s independence.

Does Olin have corporate governance guidelines and a code of conduct?

The board has adopted Principles of Corporate Governance and a Code of Conduct. The Code of Conduct applies to our directors and all of our employees, including our chief executive officer, chief financial officer, and principal accounting officer/controller. We discuss certain provisions of these documents in more detail below under the heading “Review, Approval or Ratification of Transactions with Related Persons.”

Each member of our board of directors has completed a director education course of at least eight hours in duration, accredited by RiskMetrics (formerly Institutional Shareholder Services).

Each of our three major standing board committees (Audit, Compensation and Directors and Corporate Governance) acts under a written charter adopted by the board. All of these documents can be viewed on our website at www.olin.com in the Governance section under Governance Documents and Committees or are available from the company by writing to: George H. Pain, Vice President, General Counsel and Secretary, Olin Corporation, 190 Carondelet Plaza, Suite 1530, Clayton, MO 63105. In addition, we will disclose any amendment to, or waiver from, a provision of our Code of Conduct for our directors and executive officers, including our chief executive officer, chief financial officer, principal accounting officer/controller or other employees performing similar functions on that website.

What are the committees of the Board?

Our committees of the board are:

The Audit Committee, which held seven meetings during 2007, advises the board on internal and external audit matters affecting us. The audit committee acts under a written charter adopted by the board in 1997, and reviewed and updated in 2006. In accordance with NYSE listing standards and applicable provisions of our Principles of Corporate Governance, the audit committee is comprised solely of directors who meet the enhanced independence standards for audit committee members under the Securities Exchange Act of 1934 (Exchange Act) and the related rules as incorporated into the NYSE standard for independence. Its members are: Philip J. Schulz, Chair, Randall W. Larrimore, John M. B. O’Connor and Richard M. Rompala. The board has determined that Philip J. Schulz meets the SEC definition of an “audit committee financial expert” and that each of the members of the audit committee is financially literate, as such term is interpreted by the board in its business judgment. The audit committee:

has sole authority to directly appoint, retain, compensate, evaluate and terminate our independent registered public accounting firm;

The Compensation Committee, which held seven meetings during 2007, sets policy, develops and monitors strategies for, and administers, the programs that are used to compensate the chief executive officer and other senior executives. In accordance with NYSE listing standards and applicable provisions of our Principles of Corporate Governance, the compensation committee is comprised solely of directors who meet the NYSE standard for independence. Its members are: Richard M. Rompala, Chair, Donald W. Bogus, C. Robert Bunch, Virginia A. Kamsky and Randall W. Larrimore. The compensation committee:

approves the salary plans for all executive officers including their total direct compensation opportunity, comprised of base salary, annual incentive standard and long-term incentive guideline award;

approves the measures, goals, objectives, weighting, payout matrices, performance certification and actual payouts for the incentive compensation plans;

administers the incentive compensation plans, stock option plans, and long-term incentive plans;

has the authority to hire its own independent advisors.

The compensation committee’s charter authorizes the committee to delegate certain responsibilities to internal and independent accountants, internal and outside lawyers and other internal staff.

The Directors and Corporate Governance Committee, which held three meetings during 2007, assists the board in fulfilling its responsibility to our shareholders relating to the selection and nomination of officers and directors. In accordance with NYSE listing standards and applicable provisions of our Principles of Corporate Governance, the directors and corporate governance committee is comprised solely of directors who meet the NYSE standard for independence. Its members are: Randall W. Larrimore, Chair, Donald W. Bogus, C. Robert Bunch, Virginia A. Kamsky, John M. B. O’Connor, Richard M. Rompala and Philip J. Schulz. The directors and corporate governance committee:

makes recommendations to the board regarding the election of the chief executive officer;

reviews the nominees for our other officers;

makes recommendations to the board regarding the size and composition of the board and the qualifications and experience that might be sought in board nominees;

seeks out and recommends possible candidates for nomination and considers recommendations by shareholders, management, employees and others for candidates for nomination and renomination as directors;

assesses whether the qualifications and experience of board nominees meet the current needs of the board;

reviews plans for management development and succession;

During 2007, this committee held no meetings. The executive committee members are: Joseph D. Rupp, Chair, Randall W. Larrimore, Richard M. Rompala and Philip J. Schulz.

Compensation Committee Interlocks and Insider Participation

No member of our compensation committee during the past fiscal year:

has served as an officer or employee for Olin during that fiscal year, or

has had any relationship with us requiring disclosure under Item 404 of Regulation S-K under the Exchange Act.

None of our executive officers:

serve on the compensation committee of any other company for which one of our directors serves as an executive officer, or

serve on the board of directors of any other company where a member of our Compensation Committee serves as an executive officer.

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 and Chief Executive Officer, 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 and CEO and Lead Director interview the potential board candidates selected by the committee. The interview results, along with the committee’s recommended nominees, are submitted to the full board.

Criteria for new board members include recognized achievement plus skills such as a special understanding or ability to contribute to some aspect of Olin’s business. Racial and gender diversity are important but not at the expense of particular qualifications and experience that are required to meet the needs of the board. The committee also strives to include board members with the personal qualities and experience that taken together will ensure a strong board of directors. The principal qualities of an effective corporate director include strength of character, an inquiring and independent mind, practical wisdom, and mature judgment.

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. The notice may be sent at any time, but for a candidate to be considered by the committee as a nominee for an annual shareholder 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 2009 annual meeting, we must receive the information from shareholders on or before October 13, 2008.

In addition to shareholders proposing candidates for consideration by the committee, Olin’s Bylaws allow shareholders to directly nominate individuals at the annual shareholder meeting for election to the board by delivering a written notice as described under the heading “How can I directly nominate a Director for election to the board at the 2009 meeting?” on pages 5 and 6 under the heading “Miscellaneous” above. 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.

Who presides at Executive Sessions of the Board of Directors?

In accordance with our Principles of Corporate Governance, Richard M. Rompala, our Lead Director, typically presides during executive sessions of the board’s independent directors.

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’s financial reporting process and systems of internal control, to evaluate the independence and performance of the Corporation’s independent registered public accounting firm, KPMG LLP, and internal audit functions and to encourage private communication between the audit committee and KPMG and the internal auditors.

The committee held seven meetings during the year. During the second half of 2007, 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 2007 with Management and KPMG, including the matters required to be discussed by Statement on Auditing Standards (SAS) No. 114, The Auditor’s Communication With Those Charged With Governance (Supersedes SAS No. 61, Communication With Audit Committees, as amended, AICPA, Professional Standards.)

In addition, the audit committee received a written report from KPMG covering disclosures required by Independence Standards Board Standard No. 1, INDEPENDENCE DISCUSSIONS WITH AUDIT COMMITTEES. 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 2007 audit and pre-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, 2007, to be filed with the SEC.

Review, Approval or Ratification of Transactions with Related Persons

Our Principles of Corporate Governance and our Code of Conduct include policies and procedures requiring pre-approval of certain transactions involving our directors and employees and their family members and affiliated organizations if Olin is a direct or indirect participant. The policies define “family member” to mean a spouse, child, sibling, stepchild, stepparent, mother-, father-, son-, daughter-, or sister- in-law, or any other person living with the individual (except tenants and household employees). Affiliated organizations include those entities where the individual or family member serves as a director, executive officer or holder of 5% or more of the equity interests.

Our Principles of Corporate Governance require the directors and corporate governance committee (or, if that committee determines it is appropriate, the board) to pre-approve the following transactions with directors, family members and affiliated organizations:

charitable contributions of more than $10,000 in a fiscal year,

transactions involving more than $120,000 (individually or in the aggregate) in a fiscal year (other than purchases or sales of goods and services contracted for by Olin business units in the normal course of business),

transactions in excess of $120,000 in a fiscal year for consulting or personal services,

transactions in excess of $120,000 in a fiscal year directly with (or involving direct compensation to) a director or family member, and

transactions (even in the ordinary course of business) involving the greater of $1 million or 2% of consolidated gross revenues of either Olin or the other party.

Our Code of Conduct and related Corporate Policy Statement require the approval of the board of directors before an officer may serve as a director or provide services to another organization (as an officer, employee, consultant, etc.). Any such service by other employees must be pre-approved by our President and CEO, if the potential for a conflict of interest exists. These provisions also prohibit any employee or family member from having any direct or indirect interest in, or any involvement with or obligation to, any business organization (including any non-profit entity to which Olin makes contributions) which does or seeks to do business with Olin, or any Olin competitor, without pre-approval from the employee’s department head.

In granting pre-approval, the directors and corporate governance committee, board members and management focus on the best interests of Olin.

In addition to the pre-approval process described above, our Code of Conduct and related Corporate Policy Statements prohibit any director or employee from engaging in a transaction that might conflict with the best interests of Olin.

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Exchange Act requires our officers and directors, and persons who beneficially own more than ten percent of our common stock, to file reports of ownership and changes in ownership with the SEC, and these persons must furnish us with copies of the forms they file. Officers, directors and ten-percent beneficial owners complied with all Section 16(a) filing requirements in 2007.

COMPENSATION DISCUSSION AND ANALYSIS

Compensation Objectives

We design our executive compensation policies and programs to attract, motivate and retain the highest quality executives, with a focus on shareholder return. Our goal is to compete in the market for people with the talent and skills we believe necessary to our success. We construct our executive compensation program and its various components to reflect market practices. Several components of executive compensation vary with our results to align our executives’ interests with those of our shareholders and provide a motivational element. We also design our program to provide an incentive to executives to achieve other strategic objectives consistent with our goals.

General Executive Compensation Process

Our compensation committee consists of directors determined to be independent under the NYSE listing criteria. The committee establishes total compensation opportunities (and each of the individual elements) for Joseph D. Rupp, Chairman, President and Chief Executive Officer (the CEO). The committee also approves compensation of the other named executive officers based on recommendations by the CEO.

To assist it in performing its duties, the committee engages outside executive compensation consultants. From 2000 to March 2007, our compensation committee retained Hewitt Associates, Inc. In June 2007, the committee retained Exequity LLP, an independent board and management advisory firm. Exequity does no other work for Olin. The selection of Exequity provided Olin with independent advice and continuity of key personnel providing services. In 2007, 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.

As advisor to the compensation committee, Exequity reviewed the total compensation strategy and pay levels for our named executive officers, 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.

Our compensation consultant provides significant market data to the committee, including an annual assessment of our relative position among a group of over 350 general manufacturing and services companies that we have used for benchmarking in the past several years, including 2007. Our committee reviews revenue-adjusted data from this cross-section of companies. We refer to this revenue-adjusted group as the “comparator group.” It consists of the entire community of manufacturing and services companies that participate in the Hewitt Associates Total Compensation DataBase™ (the DataBase), excluding companies that operate in energy services, retail, health services, and financial sectors. The DataBase is a widely respected source of executive compensation information, and our decision to rely on it for competitive pay information ensures that a reputable and unrelated organization actively secures and analyzes the compensation data on which our committee bases its judgment about appropriate levels of pay for our executive officers.

Our reliance on pay practices among a community as large and varied as the comparator group reflects the committee’s belief that our labor market for executive talent spans all of the manufacturing

and services community, and that the comparator group is a good representation of that labor pool. The committee did not examine the pay practices at each of the DataBase companies, nor did it study the similarities between Olin and each organization in the comparator group. Instead, the committee considered the median pay levels in the comparator group after adjusting the pay practices for an observable relationship between executive pay levels and company size and relied on those statistical representations as typifying revenue-adjusted general industry norms. It was against these norms that the committee drew its conclusions about the appropriateness of the executive officer pay levels and based its decisions about 2007 pay adjustments.

The committee determines the total target 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 levels and mix of elements for all 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. Certain components of executive compensation (such as portions of change in control payments) are based directly on salary and annual cash incentive. Other target components of compensation are linked to salary—for example annual and long-term incentive awards.

In 2007, the committee also reviewed the relationship between the CEO’s compensation and the compensation for the other named executive officers. The committee determined that the pay relationships are appropriate given the levels of individual responsibility and external standards.

From Summary Compensation Table, excluding Change in Pension Value and Non-qualified Deferred Compensation Earnings, and based on the FAS 123R value of equity awards granted in 2007. The Summary Compensation Table reflects the dollar amount we recognized in our 2007 income statement for all outstanding equity awards to the named executive officers, calculated in accordance with FAS 123R, and thus includes amounts from awards granted in 2007 and in prior years. These percentages may not be able to be derived using the amounts reflected in that table.

**	The six direct competitors for 2007 were Mueller Industries, Inc., Wolverine Tube, Inc., Occidental Petroleum Corporation, Alliant Techsystems, PPG Industries, Inc. and The Dow Chemical Company. We refer to this group of companies plus the S&P 1000 Materials companies as the Modified S&P 1000.

The percentage of total compensation allocated to each element varies by individual. The committee determines the appropriate mix of these elements after considering prevailing practices in the comparator group. Our executives also participate in certain other benefits, such as general health, life and disability insurance plans, most of which are available to all salaried employees.

As a guideline, the committee intends that expenditures with respect to base salaries, total cash compensation (salary and annual cash incentive), and total compensation (total cash plus the grant date value of long-term incentive awards) approximate the median of the comparator group practices. The committee believes that targeting the median market allows us to attract, motivate, and retain the quality executive talent Olin needs. Actual pay levels for any individual named executive officer in any year, however, may be below or above the median. The following table illustrates our intended pay positioning levels and actual compensation posture for our named executive officers in 2007:


	Base Salary	Total Cash	Total Compensation
Pay Objective	Median	Median	Median
Actual Position (relative to objective)	3% below median	4% below median	17% below median

Our general practice for an executive who is new in his/her position is to establish compensation below the market, and to increase it to market level over the first several years, assuming that performance warrants such increases. Other material increases in compensation generally relate to promotions or added responsibilities. For example, when Mr. Rupp became CEO in 2002, his base salary was well below the median of the comparator group, largely to reflect his short tenure as our CEO. During the past two years, Mr. Rupp’s salary has been near the median level of the comparator group.

Salary. The committee generally makes salary adjustments for the named executive officers on an annual basis, but when warranted by cash flow considerations, this period has been extended to 18 months or more, and we have frozen executive base salaries for periods of time. In the past 10 years, we have not decreased base salary for any named executive officer.

After reviewing comparator group practices, the committee determined that increases were required in 2007 to ensure that salaries for our executive officers approximated the market median. The committee approved the following salaries for our named executive officers, effective April 1, 2007: Mr. Rupp - $820,000; Mr. Fischer - $357,000; Mr. Pain - $364,000; Mr. McIntosh - $336,000; and Mr. McGough - $285,000. In each instance, the approved increase reflected the committee’s assessment of the officer’s trailing salary position to the market median and his experience and length of service in his role, as well as his substantial contribution to our strong 2006 performance.

Annual Cash Incentive (Non-equity Incentive Plan Compensation). Named executive officers participate in the Senior Management Incentive Compensation Plan, or SMICP, an incentive plan approved by our shareholders. The SMICP provides named executive officers with annual incentive opportunities that are comparable to those they would receive were they participants in the

annual cash incentive plan that extends to our other executives (our Management Incentive Compensation Plan, or MICP). Using the SMICP for our named executive officers allows us to deduct payments to those individuals under the requirements of Section 162(m) of the Internal Revenue Code of 1986, as amended (the Code).

The mechanics of the SMICP operation in 2007 were as follows:

At the start of the year, Exequity informed the committee of the median percentage of net income allocated by the comparator group to fund their annual incentives.

The committee then considered and approved 6% of 2007 income to be set aside to fund our maximum annual cash incentives for both the SMICP and the MICP (with income calculated as 2007 earnings per share (EPS) multiplied by the weighted average number of shares outstanding in 2007, where EPS represents consolidated net income before the after-tax effect of special charges or gains or the cumulative effect of a change in accounting, divided by the weighted average number of shares outstanding on a fully diluted basis).

The committee allocated 30% of the formulated maximum incentive pool to fund a maximum award for the CEO, 20% to fund maximum awards for the second and third highest paid named executive officers and 15% to fund maximum awards for the fourth and fifth highest paid named executive officers.

The committee exercised its discretion after the end of 2007 to award to each named executive officer such portion of his allocated fund as the committee deemed appropriate in view of our results with respect to the selected performance criteria and the individual officer’s contribution to those results.

Although the committee exercises discretion to reduce annual incentives under the SMICP, it may not increase the payments above the maximum amounts established as described above, and the payout under the SMICP may not exceed 200% of the executive’s base salary. When using its discretion to reduce annual incentives for 2007, the committee examined achievement with respect to financial goals and non-financial strategic accomplishments. In determining SMICP payments for named executive officers with company-wide responsibility (Messrs. Rupp, Fischer, Pain and McGough), the committee considered the Company’s financial performance, especially its generation of $130.4 million of income (2.7% growth over 2006), coupled with notable accomplishments relating to safety, restructuring, management of environmental liabilities, and contract negotiations with respect to strategic initiatives. In particular, the committee reviewed our successful acquisition in 2007 of Pioneer Companies, Inc. and the divestiture of our Metals business, including Chase Brass. In consideration of these results, the committee used its discretionary assessment of named executive officer performance for the year and approved the awards identified in the Summary Compensation Table. Each of these approved awards represents a reduction in award level from the recipients’ maximum permissible portion of the SMICP pool.

For Mr. McIntosh, who has divisional responsibility, the committee adopted a blended consideration of Olin and divisional accomplishments, and applied a more formulaic approach to SMICP award determination. The committee decided that 25% of Mr. McIntosh’s overall award should be a function of Olin financial and non-financial accomplishments and 75% of his overall incentive award should reflect Chlor Alkali performance (where Chlor Alkali division financial objectives were assigned a 75% weight and division non-financial strategic objectives were assigned a 25% weight). The committee’s discretionary decisions with respect to Mr. McIntosh’s SMICP award for 2007 reflected the following Chlor-Alkali division accomplishments in addition to the company achievements delineated above: Chlor-Alkali Financial factors—Pretax Income at 15% ahead of target; Operating Cash Flow that was 5% behind target; Return on Capital that exceeded target more than three-fold; and Chlor-Alkali Non-Financial Factors—improvements in safety performance and in productivity; and

major gains in sales of strategic products. After reviewing these results, the committee used its discretion to approve for Mr. McIntosh the SMICP payment identified in the Summary Compensation Table.

Long Term Incentive Compensation. In 2007, we allocated the value of long-term incentive compensation awards equally between performance shares and stock options. This combination of awards was deemed by the committee to optimize our emphasis on achieving stipulated performance goals that drive investor value and generating long-term appreciation in Olin’s stock price. The committee makes all awards to executive officers (both performance shares and stock options). The committee believes that its determination of stock option and performance share awards is highly representative of external market practices (the comparator group).

All long-term incentive compensation plan participants are assigned target award levels at values deemed by the committee to be competitive with external market practices (the comparator group). The sum of all individual target awards represents our overall long-term incentive award value. The process the committee follows to determine stock option and performance share awards is described below.

Performance Shares. Half the value of each participant’s 2007 long-term incentive target award value was delivered in performance shares. The number of performance shares awarded to each participant was formulated by dividing half the participant’s target award value by the economic value of a performance share. Each executive received a target number of performance shares in early 2007, which vest after the end of 2009, but the total number of performance shares that vest may vary between 25% and 150% of the target number. The actual number of performance shares that vest depends on our average annual return on capital for the three years ending December 31, 2009, in relation to the average annual return on capital among the Modified S&P 1000 for that period, as set forth in more detail in the chart below:


Average annual return on capital for three-year period compared to average annual return on capital for the Modified S&P 1000 for period:		Percentage of target number of performance shares that vest:
Quintile 5		150%
Quintile 4		125%
Quintile 3		100%
Quintile 2		50%
Quintile 1		25%

Olin’s return on capital performance against the Modified S&P 1000 for the relevant three-year period is determined after the data on the Modified S&P 1000 becomes available (typically the summer after the three-year period ends) and the performance shares earned are calculated and paid. Our return on capital of 9.2% for the three years ended December 31, 2006 fell in Quintile 3, and our return on capital of 6.2% for the three years ended December 31, 2005 fell in Quintile 2.

Stock Options. The remaining half of each participant’s long-term incentive target award value is delivered in stock options. Stock options are granted annually from a committee-approved pool of option shares. The pool of stock options available for issuance each year equals half the value of 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). This formulated pool of shares increases or decreases based on our trailing three-year total shareholder return (TSR) compared to the Modified S&P 1000, as follows:


Olin TSR compared to TSR for the Modified S&P 1000		Effect on number of shares available for option grants
Top third		+25%
Middle third		No change
Bottom third		- 25%

Our 2007 stock option pool was set at 75% of the aggregate pool of options because our trailing three-year TSR for the three years ended December 31, 2006 (-2.2%) fell in the bottom third of the Modified S&P 1000. We believe the Modified S&P 1000 represents our primary competition for investment capital, and therefore comprises an appropriate comparison group for performance purposes. We use TSR, which represents the increase in the fair market value of our common stock over the three-year period, including reinvestment of dividends, to tie executive rewards to our shareholders’ interests. We calculate TSR using the method we use for our Performance Graph included in our Form 10-K.

The number of stock options granted to individual long-term incentive plan participants reflects the portion of the available pool represented by the individual’s target award. The committee (or the CEO, in the case of non-officers) may increase or decrease the option grant for an individual by up to 25% from the target level, although that discretion has not been exercised.

We grant options at the first committee meeting each year. In 2008, the first committee meeting was January 25, 2008. The committee approved the granting of options on that date effective on February 7, 2008, with an exercise price of $20.29 per share, the average of the high and low per share sales price of our common stock on the New York Stock Exchange on February 7, 2008. Whenever the first scheduled meeting has occurred before or near the time we release our year end earnings report, the committee has granted stock options:

with a grant effective date approximately 10 days after the release of year end earnings, and

with the exercise price equal to fair market value (defined in our option plans as the average of the high and low sales prices of our common stock) on the grant effective date.

The practice ensures that the exercise prices of stock options reflected 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 earnings information. Our CEO has authority to grant a very limited number of options at other times during the year (no more than 50,000 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.

We have not engaged in “back dating” of options, and do not grant options with an exercise price below the average of the high and low sale prices on the effective date of the option grant.

Other Compensation. The committee occasionally approves payments to an individual or group of employees to reflect special circumstances. Effective February 7, 2008, the committee made special

restricted stock unit grants for an aggregate of 101,676 shares, to four of the named executive officers and 16 other employees. Messrs. Fischer and Pain received grants for 13,334 shares each, and Messrs. McIntosh and McGough received grants for 6,667 shares each. The restricted stock units vest on the earlier of a change in control or the third anniversary of the grant date, if the individual remains an Olin employee until that date, and accrues dividend equivalents until vesting. The committee intends to make similar restricted stock awards in 2009 and 2010 to the same employees. These awards serve as a retention incentive for a key group of officers and employees and also reward their significant efforts and contributions to the consummation of our recent restructuring activities, including the sale of our Metals businesses and the acquisition of Pioneer Companies, Inc.

We also offer certain other personal benefits to executives, primarily automobile expenses, financial counseling services and life insurance premiums (as well as the retirement and change in control benefits described below). We provide other benefits, such as a portion of health insurance premiums, to all salaried employees, while others, such as certain life insurance benefits, are provided only to the named executive officers and other senior managers. We also provide certain retirement benefits, described below. We tie these benefits to competitive practices in the market, a practice the committee believes enables us to attract and retain executives with the talents and skill sets we require.

Retirement Benefits. We offer retirement benefits as part of the package to recruit and retain employees, as well as to contribute to financial security in post-employment years. Our retirement benefits also reflect an individual’s contributions over his or her career with the company, as those benefits are based in part on the employee’s service. In general, we establish retirement benefits based on comparable programs offered by competitors. The committee believes nonqualified supplemental 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 periodically re-evaluate and update those plans to respond to changes in the market. For example, in 2005, we amended the Qualified Plan to eliminate participation for salaried employees hired on or after January 1, 2005, and as of December 31, 2007, we froze defined benefit accruals for salaried participants under the Qualified Plan, Supplemental Plan and Senior Plan. The following chart summarizes the benefits provided under our retirement plans before and after December 31, 2007, for salaried employees:


Plan Title	Participants/Purpose	Benefits Through 12/31/07	Benefits Beginning 1/1/08
Olin Corporation Contributing Employee Ownership Plan (the CEOP)—Employee Savings Account	Salaried employees are eligible to make pre-tax contributions (401(k) plan) and after-tax contributions.	Salaried employees may contribute up to 80% of eligible compensation (subject to Code limits of 2007 pre-tax contributions of $15,500). Olin annually matches the first 6% of eligible compensation the employee contributes. Olin’s matching rate of contribution is between 0% and 75% based on Olin’s earnings per share for that year.	Salaried employees may contribute up to 80% of eligible compensation (subject to Code limits of 2008 pre-tax contributions of $15,500). Olin annually matches 50% of the first 6% of eligible compensation the employee contributes.


Plan Title	Participants/Purpose	Benefits Through 12/31/07	Benefits Beginning 1/1/08
CEOP – Defined Contribution Retirement Account		For salaried employees hired on or after January 1, 2005, a contribution equal to 5% of eligible compensation is made.	For all salaried employees, Olin makes contributions to the Defined Contribution Retirement Account of 5% or 7.5% (depending on employee age) of eligible compensation.

Olin Corporation Employees Pension Plan (Qualified Plan)	Salaried employees hired before 1/1/05—to provide retirement benefits	Defined benefits upon retirement based on salary and tenure	Benefit accruals frozen as of December 31, 2007, but continued employment counts toward years of service for vesting and early retirement eligibility See discussion of additional CEOP contributions after 1/1/08 (above)

Olin Corporation Supplemental Contributing Employee Ownership Plan (Supplemental CEOP)—Employee Savings Account	Senior management —to compensate for Code limits on CEOP contributions	Eligible employees may make pre-tax contributions on eligible compensation in excess of Code limits and receive Olin matching contributions at the same percentages as the CEOP (as set forth above).	Eligible employees may make pre-tax contributions on eligible compensation in excess of Code limits and receive Olin matching contributions at the same percentages as the CEOP (as set forth above).

Supplemental CEOP— Defined Contribution Retirement Account		For eligible employees hired on or after January 1, 2005, a contribution of 5% of eligible compensation in excess of Code limits is made.	Olin makes contributions of 5% or 7.5% (depending on employee age) of eligible compensation.

Olin Supplementary and Deferral Benefit Pension Plan (Supplemental Plan)	Senior management— to compensate for Code limits on pensionable compensation under Qualified Plan	Defined pension benefits based on tenure and eligible compensation without regard to Code limits, with an offset for Qualified Plan benefits	Benefit accruals frozen as of December 31, 2007, but continued employment counts toward years of service for vesting and early retirement eligibility See discussion of additional Supplemental CEOP contributions after 1/1/08 (above).


Plan Title	Participants/Purpose	Benefits Through 12/31/07	Benefits Beginning 1/1/08
Olin Senior Executive Pension Plan (Senior Plan)	Senior management— benefits in excess of Supplemental and Qualified Plans, based on a higher percentage of compensation	Defined pension benefits based on eligible compensation and tenure, with an offset for Qualified Plan and Supplemental Plan benefits and for 50% of Social Security benefits	Benefit accruals frozen as of December 31, 2007, but continued employment counts toward years of service for vesting and early retirement eligibility

The Supplemental CEOP, the Supplemental Plan and the Senior Plan are unfunded, nonqualified deferred compensation plans for the named executive officers and a select group of other senior management employees. Because each of these three plans is unfunded, participants receive benefits only if we have the financial resources to make the payments when due. The committee believes these nonqualified supplements are commonly extended to executives at other companies, and by offering these benefits we remain competitive in the market for qualified senior-level executive talent. We describe the terms of our retirement plans in more detail in the narrative discussion following the table entitled “Pension Benefits” below.

Change in Control Agreements. We provide 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. As a retention incentive, each of our senior executives also has an agreement that provides certain benefits if the executive’s employment is terminated without cause. These agreements are described in detail under the discussion following the “Summary Compensation Table” and under the caption “Potential Payments Upon Termination or Change in Control.”

The committee gives careful attention to all aspects of executive compensation and for the reasons discussed above remains confident that our executive compensation program satisfies our objectives.

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, but we consider the tax effect of various types of compensation. The committee considers the limit on deductions for compensation over $1 million, and designs our stock options, the largest portion of our performance shares and our annual cash incentive to meet the exemption for “performance based” compensation from this deductibility limit. It is possible, however, that portions of these awards will not qualify as “performance-based compensation,” and, when combined with salary and other compensation to a named executive officer, may exceed this limitation in any particular year.

The American Jobs Creation Act of 2004 changed tax rules applicable to nonqualified deferred compensation arrangements. Olin has been in operational compliance with such rules to the extent applicable, and documentary compliance with those rules is currently required by the end of 2008. We are in the process of revising our plans and taking other steps to comply, but do not believe that the changes we are making will have a material impact on Olin.

We have no policy addressing recovery of performance-based awards to the extent financial results underlying those awards are restated, but that situation has never arisen. If it does occur, our committee would determine the appropriate action under the circumstances.

Our severance arrangements described below under “Potential Payments Upon Termination or Change in Control” provide that we will “gross up” the amount of excise tax due on “excess golden parachute payments” provisions under Code Section 280G. The committee considered this benefit in approving the terms of those agreements.

Stock Ownership Guidelines

We describe our stock ownership guidelines for directors under the heading “Director Compensation” below. Our stock ownership guidelines require executive officers and certain other senior managers to maintain specified ownership levels of our stock, based upon their positions. Under our current guidelines, our CEO is expected to attain stock ownership of at least 150,000 shares, and our other named executive officers are expected to hold at least 20,000 shares of our common stock.

We expect an executive to achieve the appropriate ownership level within five years. 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, shares held in the executive’s CEOP account, shares subject to vested stock options with an exercise price below the current market price and one-half of the unvested target performance share awards payable in stock. All of our named executive officers met these guidelines as of the end of 2007.

(1)

The named executive officers 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 named executive officers has one or more agreements that provide for certain severance benefits (including additional benefits in the event of a “change in control”). The provisions of those agreements are described in more detail under the section entitled “Potential Payments Upon Termination or Change in Control.”

(2)

Represents the dollar amount we recognized in our income statement in the appropriate year for equity awards to the named executive officers, calculated in accordance with FAS 123R, and thus includes amounts from awards granted in such year and in prior years. Please see the notes entitled “Stock-Based Compensation” and “Accounting Policies—Stock-Based Compensation” in the notes to our audited financial statements included in our 2007 annual report on Form 10-K for a discussion of the assumptions underlying these calculations.

(3)	Amounts listed in this column were determined by the committee under our SMICP.

(4)	Amounts reported in this column represent the total increase in the present value of the pension benefits during the applicable year under all of our defined benefit pension plans, and are comprised of the following items:

(a)

Present value of pension benefit from the Senior Plan decreased by $14,716 in 2006. There is no pension benefit payable from the Senior Plan in 2006 or 2007, so there is no increase in the present value of the pension benefit under that plan from 2006 to 2007.

(b)

Present value of pension benefit from the Senior Plan decreased by $29,135 in 2007 and $9,010 in 2006.

Changes in the present value of pension benefits are determined using the assumptions we use for financial reporting purposes. The discount rates were 5.75%, 6.00% and 6.25% for December 31, 2005, December 31, 2006, and December 31, 2007, respectively. We used the 1983 Group Annuity Mortality table for mortality for 2005 and 2006 and the RP2000 Mortality table for 2007. Please see the note entitled “Pension Plans and Retirement Benefits” in the notes to our audited financial statements included in our 2007 annual report on Form 10-K for a discussion of these assumptions.

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, to determine the change in the present value of the pension benefits under these plans.

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. 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)

For Messrs. Rupp, McIntosh and McGough, amounts in this column for 2006 represent proceeds from the exercise of options for shares of Arch Chemicals, Inc. common stock (issued in the 1999 spin-off of Arch Chemicals). These amounts are based on the average of the high and low sale prices on the date of exercise, but we do not make any payments in connection with Arch Chemicals options. For Mr. Fischer, the 2006 amount represents the payment of an Arch Chemicals stock appreciation right (issued in the 1999 spin-off of Arch Chemicals), at our cost.

(b)

The key executive life insurance program consists of three types of benefits: active employee life insurance, retiree life insurance and survivor income benefits. At the executive’s option, the survivor income benefit may be exchanged for additional life insurance. The amounts shown represent the total premiums we paid in each year for these benefits.

(c)

The Supplemental CEOP permits participants whose contributions to the CEOP are limited under IRS regulations to make tax deferred contributions to the Supplemental CEOP in the amount they would otherwise be permitted to contribute to the CEOP. We match these Supplemental CEOP contributions, as we would under the CEOP, and the amounts of our matching contributions made on behalf of the executives appear in this column. Through December 31, 2007, the level of the CEOP Match and Supplemental CEOP Match in each year is based on our earnings per share performance for the year. In 2006 and 2007 Olin matched 75% of the employee’s contribution (up to 6% of pay contributed to the CEOP and the Supplemental CEOP).

(d)

Amount for Mr. Fischer represents a car allowance, and amounts for other executives represent our aggregate incremental cost of the individual’s company car.

Amounts in these columns represent the potential annual cash incentives established in early 2007 under our SMICP. Actual amounts were determined and paid in early 2008 and are included under column (g) in the Summary Compensation Table above. We discuss the SMICP and our annual incentive program under the heading “Compensation Discussion and Analysis—Elements of Compensation” above.

(2)

Numbers in these columns represent awards of performance shares under our Performance Share Program described below. The amounts in column (f) reflect the minimum performance shares awarded (25% of the target amounts in column (g)). The amounts in column (h) represent 150% of such target amounts, the maximum payout of performance shares.

(3)

Numbers in these columns 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 $16.66. Our equity plans require the exercise price for option stock to be at least the “fair market value” of our common stock on the grant date, and define fair market value to mean the average of the high and low sale prices of our common stock on the grant date.

(4)

Amounts in this column assume payment of performance shares at the target level, and value options using the Black-Scholes value calculated for financial statement reporting purposes in accordance with FAS 123R. Please see the note entitled “Stock-Based Compensation” in the notes to our audited financial statements included in our 2007 annual report on Form 10-K for a discussion of the assumptions underlying these calculations.

(5)

Option awards are determined on the meeting date (in 2007, February 2, 2007). In recent years, committee meetings have been held before (or shortly after) the time we issued our year end earnings press release, and so the option awards became effective on a later date (February 13 for 2007 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.

Stock Options

Annually, we grant 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 above under the heading “Compensation Discussion and Analysis—Long Term Incentive Compensation,” and “—Stock Options.” All options granted in 2007 were non-qualified options vesting in three equal annual installments beginning on the first anniversary of the grant date. The options generally may be exercised until ten years after the grant date (but the exercise period may end earlier based on the termination of the participant’s employment).

Under our option plans, the option exercise price must be at least equal to the average of the high and low sale prices of our common stock on the date of the grant. Our option 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 above, under the heading “Stock Options” in the “Compensation Discussion and Analysis” section of this proxy statement. Our internal auditors completed an audit of our option grants in 2006 and confirmed that we had not engaged in any option “back-dating” practices.

Performance Shares

Each named executive officer and certain other key employees received a target number of performance shares in early 2007, which vest after the end of 2009. The total number of performance shares that vest may vary between 25% and 150% of the target number, based on our average annual return on capital for the three years ending December 31, 2009, in relation to the average annual return on capital among the Modified S&P 1000 for that period. The chart included in the discussion of performance share awards in the “Compensation Disclosure and Analysis” above sets forth this relationship in more detail. Vested performance shares are paid approximately half in cash and half in stock.

For all individuals except Mr. McGough, the shares listed in column (d) above represent performance shares paid in the summer of 2007 (vested based on our performance for the three years ended December 31, 2006) under a performance share award made in early 2004. Performance shares are paid approximately half in cash and half in stock. The cash portion of the performance shares payment was based on the fair market value of the shares as of December 29, 2006 ($16.65), and dollar amounts listed in column (e) for the stock portion of the payment of performance shares are based on the average of the high and low sales prices for our common stock as of the date the shares were issued ($20.67), August 22, 2007. Of the total performance shares included in column (d) above, 25% vested automatically, and the remaining shares vested based on our average annual return on capital for the three-year period ended December 31, 2006, compared to that of the S&P MidCap 400. We describe our performance share program in more detail in our “Compensation Disclosure and Analysis—Elements of Compensation” and in the text following the table entitled “Grants of Plan-Based Awards.” The shares listed in column (d) for Mr. McGough represent the payout of a 3,500 share restricted stock grant on February 12, 2007 (from which 1,032 shares were withheld for tax obligations, for a net delivery of 2,468 shares). The dollar amount in column (e) for Mr. McGough represents the average of the high and low stock prices on the vesting date ($16.24) multiplied by the total number of restricted shares vested, plus the amount ($8,177) of dividend equivalents and interest paid.

PENSION BENEFITS

The table below shows the present value of the benefits under each of the pension plans as of December 31, 2007 for each named executive officer. The present values are calculated using:

the executive’s average compensation (salary and annual incentive, and specific inclusions and exclusions that vary by plan) for the three highest years out of the last ten years of employment,

years of creditable service under each of the plans as of December 31, 2007,

age 62, the first age at which unreduced pension benefits are payable under each of the pension plans, and

the assumptions we used for financial reporting as of December 31, 2007, including a 6.25% discount rate and the RP2000 Mortality table.

Please see the note entitled “Pension Plans and Retirement Benefits” in the notes to our audited financial statements included in our 2007 annual report on Form 10-K for a discussion of these assumptions.

(1)	The Qualified Plan is the Olin Corporation Employees Pension Plan, the Supplemental Plan is the Olin Supplementary and Deferral Benefit Pension Plan, and the Senior Plan is the Olin Senior Executive Pension Plan, each of which is described below.

(2)	Participation in the Senior Plan begins when the executive becomes a Section 16(b) reporting officer and is selected by the committee, whereas participation in the Qualified and Supplemental Plans generally includes all years of service from the executive’s hire date through December 31, 2007.

(3)	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.

Effective December 31, 2007, all benefits under the Qualified Plan, the Senior Plan and the Supplemental Plan were frozen, so that benefits payable under those plans will be based on the benefits accrued as of December 31, 2007. Employment with Olin after that date will count toward meeting the service and age requirements for vesting and early retirement. Currently, Messrs. Rupp, Pain and McGough are eligible for early retirement.

The executive may elect benefits for his or her life (which we sometimes refer to as a “single life annuity”) or to have payments continue after his or her 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 named executives under these plans, assuming the

executive elected the joint and survivorship benefit and retired at age 62, (the first age at which unreduced pension benefits are payable under the plans):


Name	Qualified Plan		Supplemental Plan		Senior Plan
Joseph D. Rupp	$	938,503	$	5,727,607	$	540,534
John E. Fischer	$	433,034	$	729,194	$	221,717

John L. McIntosh	$	611,247	$	1,065,637	$	277,858
Dennis R. McGough	$	831,267	$	796,524	$	278,552

Freeze of Qualified Plan, Supplemental Plan and Senior Plan

As noted above, benefits accrued by salaried participants in the Qualified Plan, Supplemental Plan and Senior Plan were “frozen” effective December 31, 2007. 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 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.

Qualified Plan

As part of a competitive benefits program and to contribute to employees’ financial security in retirement, we offer 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 ten years the individual is employed by Olin, through December 31, 2007. The law requires that in determining eligible compensation, the Qualified Plan ignore compensation in excess of a legally-imposed cap (which for 2007 was $225,000). An employee’s benefit is generally 1.5% of his or her average compensation 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 5 years of service (but less than 10 years of service) receive a vested retirement benefit beginning the month after their 65^th 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.

Supplemental Plan

The Supplemental Plan is an unfunded, nonqualified deferred compensation plan for select management employees. 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 deferred and 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 on an immediate basis to a participant whose employment terminates at age 55 or later, with at least 10 years of service, using the same reduction factors as the Qualified Plan.

Senior Plan

The Senior Plan is an unfunded, nonqualified deferred compensation plan for select management employees. An employee who is a Section 16(b) reporting officer, and who is selected by the committee, may participate 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 ten that he or she is employed by Olin, including the year of retirement. 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.

To the extent benefits under the Senior Plan and Supplemental Plan have an actuarial present value in excess of $100,000, benefits are paid monthly during the first year and then in a lump sum, one year after retirement (or at age 65 if the employee was not eligible for early retirement). The executive may elect to receive monthly benefits rather than the lump sum.

If a participant in the Senior Plan and Supplemental Plan is a specified employee as defined in Code Section 409A, benefits subject to that Code provision 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.

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 by paying the same premium as active salaried employees. When the average per capita cost for our health plan retirees exceeds $10,000, the retiree will be required to pay the amount of the premium paid by active salaried employees plus the amount by which our average per capita cost for the health plan retirees 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.

In general, salaried employees who retire from Olin 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, at our cost.

NONQUALIFIED DEFERRED COMPENSATION

The following table sets forth information with respect to our Supplemental CEOP for each of our named executive officers for 2007:

Dennis R. McGough	4,060	2,610	9,377	0	34,940

(1)	Amounts in this column are included in the executives’ salaries listed in column (c) of the Summary Compensation Table.

(2)	Amounts in this column are included in the amounts listed in column (i) of the Summary Compensation Table and represent 2007 company matching contributions which will be credited to the participants’ Supplemental CEOP accounts in 2008.

In addition to our CEOP, discussed above under the heading “Compensation Discussion & Analysis—Elements of Compensation—Retirement Benefits,” our Supplemental CEOP provides deferral and company matching opportunities to employees whose contributions to the CEOP are limited under the Code because their base pay exceeds the Code’s compensation limit ($225,000 for 2007). These employees can make pre-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 contributions from Olin at the same level Olin matches CEOP contributions.

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 for 90-day commercial paper plus 10 basis points at the end of the last quarter, or (ii) such other rate as our Board or compensation committee (or any delegate thereof) select in advance from time to time.

Distributions are paid in cash, in a lump sum or in annual installments for up to fifteen (15) years, 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 New York Stock Exchange for the month before the distribution. Distributions from the interest bearing fund equal the dollar value of the (principal and interest). If a participant in the Supplemental CEOP is a specified employee as defined in Code Section 409A, benefit payments subject to that Code provision begin as soon as practicable after six months after employment ends.

POTENTIAL PAYMENTS UPON TERMINATION OR CHANGE IN CONTROL

Certain agreements with our named executive officers provide compensation in the event of a termination of employment or a change in control of Olin.

1.	Amounts in the tables assume an annual base salary at the executive’s level as of December 31, 2007.

Messrs. Rupp, Pain and McGough are eligible for early retirement, so amounts in this table reflect amounts they would receive upon early retirement. Messrs. Fischer and McIntosh are not currently eligible for early retirement, and so the amounts reported for them under the “Benefits and Perquisites” section represent the present value of the benefits, assuming the benefits begin at age 65.

Because the freeze of defined benefits discussed above did not become effective until the close of business on December 31, 2007, the amounts executives would receive under the Qualified Plan, the Senior Plan and the Supplemental Plan upon a termination without cause will vary depending on whether the event occurred on December 31, 2007 or on or after January 1, 2008. The tables above include columns showing amounts as if the event had occurred on December 31, 2007, as required by applicable SEC rules, and as if the event had occurred the next day.

An executive whose employment terminates in connection with a 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.

Olin 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) willfully breaches Olin’s Code of Conduct; or (iv) commits a felony or fraud in the course of his or her employment.

Because the freeze of defined benefits discussed above did not become effective until the close of business on December 31, 2007, the amounts executives would receive under the Qualified Plan, the Senior Plan and the Supplemental Plan upon a change in control will vary depending on whether the event occurred on December 31, 2007 or on or after January 1, 2008. The tables above include columns showing amounts as if the event had occurred on December 31, 2007, as required by applicable SEC rules, and as if the event had occurred the next day.

Upon a change in control, benefits listed for the Senior Plan, Supplemental Plan, and Supplemental CEOP would be paid immediately. All restricted stock and performance share awards would be vested and paid. All options and stock appreciation rights would vest immediately and be fully exercisable. All other amounts would be paid only if the executive is terminated or constructively terminated upon or within three years after a change in control. Constructive termination occurs when the executive terminates his or her employment 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 substantially the same basis as before the change in control, (iii) Olin fails to maintain its benefit plans as in effect prior to the change in control, or (iv) the executive is assigned duties inconsistent with duties prior to the change in control or Olin takes actions that result in a diminution of the executive’s responsibilities.

6.	Severance payments on termination without cause equal base salary plus the higher of the target incentive award under the SMICP or the average SMICP payment during the past three years. In the event of a change in control it is three times this total amount.

An executive whose employment terminates as the result of disability, death, or retirement receives a pro rata share of unvested performance share awards (based on the number of months worked in the performance cycle) payable in cash at the time it would otherwise be payable. We have assumed payouts at the level of 25% of the target unvested performance shares and performance shares vested at December 31, 2007, but not yet paid. 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—see footnote 8. 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.	Represents cash payout for automatic vesting of unvested restricted stock, stock options and performance shares on change in control.

Unused vacation is paid to all salaried employees and is therefore not included in this table. Medical benefits are provided to all salaried employees who are eligible for early retirement. Because Messrs. Rupp, Pain and McGough are currently eligible for early retirement; no amount is reported for medical benefits for them. Mr. Fischer would be eligible for one year of healthcare benefits coverage in the event of an involuntary, not for cause termination at the estimated cost of $17,154, and for two years and five months of healthcare benefits coverage in the event of a change in control at an estimated cost of $57,501. Mr. McIntosh would be eligible for one year of healthcare benefits coverage in the event of an involuntary, not for cause termination at an estimated cost of $19,333, and for one year and four months of healthcare coverage in the event of a change in control, at an estimated cost of $40,717.

10.

The Senior Plan 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 joint and survivorship benefit under the Qualified Plan and the Supplemental Plan. The value of the 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.

Unless the executive elects otherwise, benefits from the Senior Plan and the Supplemental Plan will be paid in the form of a lump sum if the present value is $100,000 or greater, one year following the executive’s retirement date (with monthly payments commencing after 6 months and continuing until such one year date. The first such payment includes a retroactive payment for the first 6 months.) 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 RP 2000 Mortality table. The benefits reported for the Senior Plan and Supplemental Plan are based on these assumptions, except with respect to a Change in Control.

In the event of a Change in Control, each executive 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 tables above assume a 50% joint and survivorship benefit and use the discount rate applicable for the situation described and the RP 2000 Mortality Table. If the 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

Upon the death of a former executive, his or her estate receives life insurance benefits based on base salary if he or she was at least age 55. As of December 31, 2007, Mr. Rupp would have $123,000, Mr. Pain would have $37,000, and Mr. McGough would have $58,000, of life insurance coverage. Messrs. Fischer and McIntosh are not eligible for these life insurance benefits until age 55.

An executive terminated due to disability would receive disability benefits equal to 60% or 75% of base salary, depending on the level of coverage he or she elected, until the executive is no longer disabled, reaches age 65, or elects to take early retirement benefits. At that time, the executive would receive the applicable retirement benefits described above. Messrs. Rupp, McIntosh and McGough have elected the 75% level of coverage. Messrs. Fischer and Pain have elected the 60% level of coverage.

Executive Severance and Executive Change in Control Agreements

As of December 31, 2007, we had executive severance agreements (“executive agreements”) and executive change in control agreements (“CIC agreements”) with all of the named executive officers, and with three other executive officers, expiring on January 26, 2011. Beginning January 26, 2009 and each year thereafter, the term of these agreements extends by an additional year unless we provide at least 90 days notice that the term will not be extended. If a change in control (as defined in the CIC agreement) occurs, the CIC agreement extends for at least three years after the change in control. The committee established the terms of the CIC agreements and the executive agreements (including the level of payments in various scenarios) based on advice from Exequity and from outside benefits counsel regarding marketplace practices for comparable companies.

CIC Agreement. The CIC agreement contains a complex definition of “change in control,” but generally a change in control occurs if:

(1) a person or entity acquires control of 20% or more of our common stock unless (a) the acquiring party is Olin, its subsidiaries or benefit plans, an underwriter holding the shares temporarily for an offering, the executive who is a party to the CIC agreement or an entity that the executive controls or (b) the percentage increase occurs solely because the total number of shares outstanding is reduced by Olin buying its stock back;

(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, absent an election 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 our shareholders own more than half of the voting interest of Olin or the new company (in approximately the current ratios) after the transaction, and neither of the events in items (1) and (2) above has occurred for Olin or the new entity; or

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

If, after a change in control, the executive’s employment is terminated by Olin without “cause” or by the executive as a result of disability or adverse changes in the terms of employment, the executive will:

receive a cash severance payment equal to three times the executive severance amount (as described below),

receive an additional 36 months of insurance coverage,

be treated as if he or she had remained employed (for service purposes) for 36 months after termination, including receiving 36 months of retirement contributions to all Olin defined contribution plans based on the amount of the cash severance,

be entitled to continue in Olin’s medical and dental coverage (including dependent coverage) until age 65, on terms and conditions no less favorable than those in effect prior to the change in control, although such coverage is secondary to coverage from the executive’s new employer, if any,

receive up to 12 months of outplacement services, and

if termination occurs after the first calendar quarter, receive a prorated annual incentive compensation award for that year.

These payments and benefits are not conditioned on any waiver, release or noncompete. The CIC agreement also provides that if any payments made to the executive subject the executive to the excise tax under Section 4999 of the Code, the payment increases to provide the executive with a net payment as if such tax did not apply.

Executive Agreement. If the executive’s employment is terminated (in a non change in control event) by Olin without cause, the executive will receive, in lieu of severance benefits under 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) the greater of the executive’s average annual incentive compensation award for the last three calendar years or the executive’s then current target annual incentive compensation award;

(2)

twelve 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 twelve months after the termination);

(3)

twelve 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.

The executive must sign a waiver and general release of claims and agree to one-year noncompetition and nonsolicitation covenants to receive any severance payments and other benefits.

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 apply to any termination from the new employment for twelve months. Payments by Olin are reduced for any cash severance or similar benefits from such buyer or joint venture.

Treatment of Equity Awards

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,

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

unvested performance-accelerated vesting options granted in 2000 do not terminate upon retirement, but continue until vested or the termination date.

Change in Control. On a change in control (as defined under the CIC agreement):

all options vest (and in certain cases, convert to stock appreciation rights), and

all restricted stock and performance share awards vest and are paid.

Pension Plans

Qualified Plan. The Qualified Plan provides that if, within three years after a change in control (as defined in the Qualified Plan), any corporate action is taken or filing made in contemplation of events such as a plan termination or merger or other transfer of assets or liabilities of the plan, and such event later takes place, plan benefits automatically increase to absorb any surplus plan assets. Under the Qualified Plan, a change in control occurs if:

(1)

we are no longer publicly owned with at least 1,000 shareholders,

(2)

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

(3)

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

(4)

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 more than half of the voting interest of the new company, or

(5)

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

Supplemental Plan. In the event of a change in control (as defined in the Supplemental Plan), we will pay each eligible employee a cash amount sufficient to purchase an annuity that provides the monthly after tax benefit the employee would have received under the Supplemental Plan (based on benefits accrued as of the change in control). The payment is reduced for monthly payments under trust arrangements or other annuities we establish or purchase to make payments under this plan. The Supplemental Plan defines a change of control in the same way as the Qualified Plan, but adds mergers or other transactions where Olin is the surviving corporation.

Senior Plan. In the event of a change in control (as defined in the Supplemental Plan), the Senior Plan pays qualified executives a cash amount sufficient to purchase an annuity that provides the after-tax benefit the employee would have received under the Senior Plan (based on benefits accrued as of the change in control).

DIRECTOR COMPENSATION

In 2007, our compensation package for non-employee directors consisted of:

an annual retainer of $30,000 of which at least $25,000 must be taken in shares of common stock (based upon the average high and low sale prices on February 8, 2007) (for 2008, the annual retainer will increase to $40,000 with at least $25,000 taken in shares of common stock);

phantom stock units with an aggregate fair market value equal to $50,000 rounded to the nearest 100 shares (for 2008, this amount will increase to $65,000);

a fee of $2,000 for each board meeting and each committee meeting attended;

a $25,000 annual fee for the Lead Director (and an additional one-time payment of $50,000 to the Lead Director in recognition of the extraordinary contributions and time committed to support our restructuring activities during 2007, beyond his regular duties as Lead Director);

a $10,000 annual fee for the chair of each of the Audit, Compensation and Directors and Corporate Governance Committees;

reimbursement for expenses incurred in the performance of their duties as directors;

participation in our charitable gift program available to all salaried employees, where we make a 50% matching contribution (up to $5,000 per year) for the director’s gifts to certain eligible charities; and

director liability insurance, personal excess liability coverage of $5 million per director, and coverage under our business travel accident insurance policy while on Olin business.

The table below shows all cash and stock retainers, meeting fees and other compensation we paid to each of our non-employee directors during 2007. Each of the directors listed below served for the entire year, except for Mr. Griffin who served until his retirement in late April of 2007.

(1)

Represents amount recognized in our 2007 income statement in accordance with FAS 123R, and includes amounts otherwise payable in cash which the director elected to defer as phantom stock units under the Directors Plan. The amounts in this column equal the grant date fair value of the awards. The following table lists the phantom stock units held by each director in his or her deferred stock account at December 31, 2007 (payable upon the director’s retirement from our board, or later dates selected by the director, in cash or stock at the director’s election):


Name		Total Deferred Stock Account Balance (in Shares)*
Donald W. Bogus		6,092
C. Robert Bunch		13,562
Donald W. Griffin		0
Virginia A. Kamsky		7,800
Randall W. Larrimore		35,448
John M.B. O’Connor		12,943
Richard M. Rompala		56,821
Anthony W. Ruggiero		9,154
Philip J. Schulz		11,793

Total includes stock awards of the type listed in column (c) above and dividend equivalents on phantom stock units held in the deferred stock account.

(2)	Consists of insurance premiums we paid for excess liability insurance coverage in the amount of $782 and any amounts we contributed to charity on behalf of the director under our matching charitable gifts program.

(3)	Represents amounts payable currently (the director elected to defer to a cash account to be paid on retirement from Olin’s board, or at a later date he/she selects).

The board of directors determines the total amounts of the annual retainer, meeting, lead director and board/committee chair fees, based on recommendations from the committee and input from Exequity. All stock-based compensation for our directors is governed by our Amended and Restated 1997 Stock Plan for Non-employee Directors, which we refer to as our “Directors Plan.”

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, 35% 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.

Two directors held shares of Olin common stock in their deferred accounts under the Directors Plan at the time of the spin-off of Arch Chemicals, Inc. on February 8, 1999. Those directors received “phantom” shares of common stock of Arch Chemicals, Inc. as a dividend distribution in connection with the spin-off. The Arch Chemicals, Inc. phantom shares are payable only in cash, unless a director transfers the Arch Chemicals, Inc. phantom shares into his Olin common stock account before he leaves our board.

We have stock ownership guidelines for our non-employee directors that all of our non-employee directors have met. The guidelines require each such director 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. All of our directors currently meet the guidelines.

COMPENSATION COMMITTEE REPORT

The Compensation Committee has reviewed and discussed the Compensation Discussion and Analysis with management and, based on the review and discussions, recommends that it be included in Olin’s annual report on Form 10-K and Proxy Statement for the 2008 Annual Shareholder Meeting.

ITEM 2—PROPOSAL TO RATIFY APPOINTMENT OF

INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

KPMG LLP was our independent registered public accounting firm for 2007 and 2006. A summary of the KPMG fees by year follows:


	Fees ($ in thousands)
	2007				2006
Nature of Service	$		%		$		%
Audit Fees (1)	$	1,887	86	%	$	1,784	100	%
Audit Related Fees (2)		300	14			—	—
Tax Fees
Tax Compliance		—	—			—	—
Tax Consultation and Planning		—	—			—	—
All Other Fees		—	—			—	—

	$	2,187	100	%	$	1,784	100	%

(1)	Includes costs associated with the annual audit, including quarterly financial reviews, services required under Section 404 of the Sarbanes-Oxley Act, statutory audits, comfort letters, attest services, consents and assistance with and review of filings with the SEC.

(2)	Costs include services related to the carve out audit of the Metals Division.

Our audit committee has a policy that all audit services by any independent registered public accounting firm and all non-audit services performed by our independent registered public accounting firm are subject to pre-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 for pre-approving all audit services by any independent registered public accounting firm and all non-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 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 pre-approved services must be approved by the committee. In the event that approval is needed for a service in advance of a regularly scheduled audit committee meeting, the Chair of the committee is authorized to approve the service and report such approval to the other committee members at the next regularly scheduled committee meeting.

In 2007, the audit committee pre-approved all audit and audit-related services and all tax services.

Who has the Audit Committee selected as Olin’s independent registered public accounting firm for 2008?

Olin’s audit committee is solely responsible for hiring and compensating the Company’s independent registered public accounting firm. After considering KPMG’s 2007 performance and their proposed audit plan for 2008, the committee has selected KPMG as our independent registered public accounting firm for 2008.

Is a shareholder vote required to approve Olin’s independent registered public accounting firm?

The law and our Bylaws do not require us to submit this matter to the shareholders at the annual meeting. However, the board and audit committee chose to submit it to the shareholders to ascertain their views.

Will I have an opportunity to hear from KPMG and ask them questions?

We expect representatives of KPMG to be present at the annual meeting. They will have an opportunity to make a statement, if they desire to do so, and to respond to appropriate questions.

How many votes are required to ratify the appointment of KPMG as Olin’s independent registered public accounting firm for 2008?

To ratify the appointment of KPMG as Olin’s independent registered public accounting firm for 2008, the votes cast in favor of KPMG must exceed the votes cast in opposition to KPMG. Abstentions and shares held in street name that are not voted will not be included in determining the number of votes cast and will not affect the vote on this proposal. If the shareholders’ ratification vote does not support the audit committee’s decision to appoint KPMG as Olin’s independent registered public accounting firm for 2008, the audit committee will take the vote into consideration in making next year’s selection.

How does the Board recommend we vote?

The board recommends that you vote FOR ratification of the appointment of KPMG as our independent registered public accounting firm for 2008.
