                        ANNUAL MEETING OF SHAREHOLDERS

                           To be Held April 26, 2001

   This Proxy Statement is furnished to the shareholders of Olin Corporation
(''Olin'' or the ''Company'') in connection with the solicitation by the Board
of Directors of Olin of proxies to be voted at the Annual Meeting of
Shareholders to be held on April 26, 2001, and at any adjournment thereof.
Shares represented by duly executed proxies in the accompanying form received
by Olin prior to the meeting will be voted at the meeting. Where a shareholder
directs in the proxy a choice regarding any matter that is to be voted on, that
direction will be followed. If no direction is made, proxies will be voted for
the election of directors as set forth below, and in favor of each of the other
matters listed in the proxy. Any person who has returned a proxy has the power
to revoke it at any time before it is exercised by submitting a subsequently
dated proxy, by giving notice in writing to the Secretary or by voting in
person at the meeting.

   As of the date hereof, Olin does not know of any matters other than those
referred to in the accompanying Notice which are to come before the meeting. If
any other matters are properly presented for action, the persons named in the
accompanying form of proxy will vote the proxy in accordance with their best
judgment. The mailing address of Olin's principal executive office is 501
Merritt 7, PO Box 4500, Norwalk, CT 06856-4500. This Proxy Statement and the
related proxy card are first being mailed to shareholders on or about March 13,

                    SHARES OUTSTANDING AND ENTITLED TO VOTE

   The close of business on March 1, 2001 has been fixed as the record date for
the meeting and any adjournment thereof. As of that date, there were
approximately 43,821,410 shares of Olin common stock, $1 par value (''Common
Stock''), outstanding, each of which is entitled to one vote. Of those shares
of Common Stock outstanding, approximately 8,180,931 shares were held in the
Olin Common Stock Fund of the Olin Corporation Contributing Employee Ownership
Plan (''CEOP''), all of which are held by The Chase Manhattan Bank, NA as the
Trustee of the CEOP. Each individual participating in the CEOP is entitled to
instruct the Trustee how to vote all shares of Common Stock credited to the
individual through the individual's contributions and through matching
contributions by Olin. Shares of Common Stock held in the CEOP for which voting
instructions are not received from CEOP participants or which are not credited
to participants' accounts are voted by the Trustee in the same proportion as
shares of Common Stock for which the Trustee has received instructions.

   Mellon Investor Services ("MIS") is Olin's registrar and transfer agent. For
holders of Common Stock who participate in the Automatic Dividend Reinvestment
Plan offered by MIS, MIS will vote any shares of Common Stock that it holds for
the participant's account in accordance with the proxy returned by the
participant covering his or her shares of record. If a participant does not
send in a proxy for shares of record, MIS will not vote Dividend Reinvestment
shares of such participant.

   Except as indicated below, Olin knows of no person who was the beneficial

                         ITEM 1--ELECTION OF DIRECTORS

   The Board of Directors is divided into three classes with the term of office
of each class being three years, ending in different years. Two persons, as set
forth below under ''Nominees for Three-Year Terms Expiring in 2004'', have been
nominated by the Board for election as Class I Directors to serve until the
2004 Annual Meeting of Shareholders and until their successors have been
elected. The terms of the other directors will continue after the meeting as
indicated below.

   Each of the nominees is a director at the present time. It is not expected
that any of the nominees will be unable to serve as a director but if any are
unable to accept election, it is intended that shares represented by proxies in
the accompanying form will be voted for the election of substitute nominees
selected by the Board, unless the number of directors is reduced.

   The election of each nominee as a director requires the affirmative vote of
a plurality of the votes cast in the election. Abstentions and shares held in
street name (''Broker Shares'') that are not voted in the election of directors
will not be included in determining the number of votes cast.

                NOMINEES FOR THREE-YEAR TERMS EXPIRING IN 2004

            ADDITIONAL INFORMATION REGARDING THE BOARD OF DIRECTORS

Attendance

   During 2000, the Board held eight meetings. The average attendance by
current directors at meetings of the Board and committees of the Board on which
they served was 90%. Each such director attended at least 75% of such meetings.

Committees of the Board

   The current standing committees of the Board are an Audit Committee, a
Compensation Committee, a Directors and Corporate Governance Committee and an
Executive Committee.

   The Audit Committee advises the Board on internal and external audit matters
affecting Olin, including recommendation of the appointment of independent
auditors of Olin; reviews with such auditors the scope and results of their
examination of the financial statements of Olin and any investigations and
surveys by such auditors; reviews reports of and audits by Olin's Internal and
Regulatory Audit Departments; and reviews the presentation of Olin's financial
results. The Committee also monitors the Corporation's litigation and insurance
and risk management process, oversees the Company's ethics and business conduct
programs and procedures, and major litigation and other legal matters that
impact the Company's financial statements or compliance with the law. During
2000, this committee held four meetings.

   The Compensation Committee sets policy, develops and monitors strategies
for, and administers the programs which compensate the Chief Executive Officer
(''CEO'') and other senior executives. The committee approves the salary plans
for the CEO and other senior executives including their total direct
compensation opportunity, and the mix of base salary, annual incentive standard
and long-term incentive guideline award. It approves the measures, goals,
objectives, weighting, payout matrices and actual payouts and certifies
performance for and administers the incentive compensation plans. The committee
administers stock option plans and the long term incentive plans, issues an
annual report on Executive Compensation that appears in the Proxy Statement,
approves Executive and Change in Control Agreements, approves and adopts new
qualified and non-qualified pension plans, approves terminations of qualified
and non-qualified pension plans, approves the interest rate for deferred
compensation arrangements, administers the Senior Executive Pension Plan, and
makes recommendations to the Board on any other matters pertaining to the
pension, CEOP and other plans which the committee deems appropriate. The
committee also advises the Board on the remuneration for members of the Board.
During 2000, this committee held four meetings.

   The Directors and Corporate Governance Committee assists the Board of
Directors in fulfilling its responsibility to the Company's shareholders
relating to the selection and nomination of Directors, makes recommendations to
the Board of Directors regarding the election of the Chief Executive Officer,
reviews the nominees for other offices of the Company, annually evaluates the
performance of the Chief Executive Officer, reviews plans for management
development and succession, periodically reviews corporate governance trends,
issues and best practices and makes recommendations to the Board regarding the
adoption of best practices most appropriate for the governance of the affairs
of the Board of Directors, recommends to the Board of Directors a slate of
nominees to be proposed for election to the Board by shareholders at annual
meetings and at other appropriate times, recommends individuals to fill any
vacancies created on the Board of Directors, makes recommendations to the Board
of Directors regarding the size and composition of the Board, the particular
qualifications and experience that might be sought in Board nominees, assesses
whether the qualifications and experience of candidates for nomination and
renomination to the Board meet the then current needs of the Board, seeks out
possible candidates for nomination and considers suggestions by shareholders,
management, employees and others for candidates for nomination and renomination
as Directors, reviews and makes recommendations to the Board of Directors
regarding the composition, duties and

                                       6


responsibilities of various Board committees from time to time as may be
appropriate, reviews and advises the Board on such matters as protection
against liability and indemnification, and assesses and reports annually to the
Board on the performance of the Board itself as a whole. During 2000, this
committee held three meetings.

   The By-laws require that advance notice of nominations for the election of
directors to be made by a shareholder (as distinguished from a shareholder's
recommendation to the Directors and Corporate Governance Committee) be given to
the Secretary of Olin no later than 90 days before the anniversary of the
immediately preceding annual meeting of shareholders, together with the name
and address of the shareholder and of the person to be nominated; a
representation that the shareholder is entitled to vote at the meeting and
intends to appear there in person or by proxy to make the nomination; a
description of arrangements or understandings between the shareholder and
others pursuant to which the nomination is to be made; such other information
regarding the nominee as would be required in a proxy statement filed under the
Securities and Exchange Commission (''SEC'') proxy rules; and the consent of
the nominee to serve as a director if elected.

   The Executive Committee meets as needed in accordance with Article IV,
Section 1 of the Corporation's By-laws. During the intervals between the
meetings of the Board, the Executive Committee may exercise all the power and
authority of the Board (including the management, control and direction of the
financial affairs of the Corporation) except with respect to those matters
reserved to the Board by Virginia law, in such manner as the Executive
Committee shall deem best for the interests of the Corporation, in all cases in
which specific directions shall not have been given by the Board. During 2000,
this committee held no meetings.

Compensation of Directors

   During 2000, each non-employee member of the Board received an annual
retainer of $30,000, at least $25,000 of which was paid or credited in the form
of shares of Common Stock as provided in the amended and restated 1997 Stock
Plan for Non-employee Directors (the ''Directors Plan''). Each non-employee
director also was credited with a number of shares of Common Stock with an
aggregate fair market value equal to $24,000, rounded to the nearest 100
shares, (prorated based on the date the director joins the Board, for those
directors serving less than a full year). The Directors Plan also permits each
director to elect to receive his or her meeting fees in the form of shares of
Common Stock in lieu of cash and to elect to defer any stock or cash payments
under the Directors Plan. Directors also could elect to receive the amount by
which the annual retainer exceeds $25,000 in the form of shares of Common Stock
in lieu of cash.

   Deferred cash is credited with interest quarterly and deferred shares are
credited with dividend equivalents. Deferred shares are paid out in shares of
Common Stock, or at the director's election in cash. The Directors Plan also
holds, as ''phantom'' shares, the shares of Common Stock of Arch Chemicals,
Inc. (''Arch Chemicals'') issued to the directors as dividends on their shares
of Olin Common Stock held in the Directors Plan in connection with the spin-off
of Arch Chemicals. Those phantom Arch Chemicals shares are payable only in
cash, unless a director elects to transfer the phantom shares into his or her
Olin Common Stock account under the Directors Plan. Deferred accounts under the
Directors Plan are also paid out if there is a ''Change in Control'' as defined
in such plan.

   During 2000, directors who were not employees of Olin were paid a fee of
$1,500 for each meeting of the Board and for each meeting of a committee of the
Board attended, together with expenses incurred in the performance of their
duties as directors. Committee chairs also received a $5,000 annual fee.

   Directors who are not officers or employees of Olin are also covered under
the Company's matching gift plan whereby the Company will make a 100% match of
gifts totaling up to $5,000 by the director to an eligible institution.
Directors who are not officers or employees of Olin or one of its subsidiaries
are covered while on Company business under Olin's business travel accident
insurance policy which covers employees of the Company generally.

Section 16(a) Beneficial Ownership Reporting Compliance

   Section 16(a) of the Securities Exchange Act of 1934 requires Olin's
officers and directors, and persons who own more than ten percent of a
registered class of Olin's equity securities, to file reports of ownership and
changes in ownership with the SEC and the New York Stock Exchange. Officers,
directors and greater than ten-percent shareholders are required by SEC
regulation to furnish Olin with copies of all Section 16(a) forms they file.
Based solely on a review of the copies of such forms furnished to Olin and
written representations, Olin believes that during the period January 1, 2000
to December 31, 2000, all Section 16(a) filing requirements applicable to its
officers, directors and greater than ten-percent beneficial owners were
complied with.

                            EXECUTIVE COMPENSATION

        Report of the Compensation Committee on Executive Compensation

Executive Compensation Program as Administered in 2000


   The Compensation Committee has established competitive total compensation
opportunities (and each component thereof) for the CEO and other named
executive officers that are targeted to the median of a group of 21 companies
(the ''comparator group'') that are similar in size, scope of operations and
represent businesses competing in the chemicals, metals and metal products
industries. Independent consultants provide the Committee with an annual
assessment of the Company's relative positions within this comparator group
with respect to performance and total compensation which includes each of the
following components:

    .  annual base salary

    .  annual incentive bonus

    .  long term incentive award

   Together, these three components comprise the total targeted compensation
opportunity determined by the competitive analysis cited above. Once the total
targeted compensation opportunity is determined for the CEO and the other named
executive officers, the Compensation Committee, also with the advice of outside
consultants, determines the appropriate mix of these three components, again
using the competitive analysis. With the focus on creating alignment between
the compensation program and shareholders' interests, the emphasis of the
Company's executive compensation is on variable compensation. This emphasis is
also consistent with competitive practice.

   The objectives of the Company's executive compensation policies and programs
are to:

    .  attract, motivate and retain the highest quality executives,

    .  align executive interests with those of the Company's shareholders,

    .  provide an incentive to executives to achieve quantifiable financial and
       other strategic objectives in a manner consistent with the Company's
       values, and

    .  unite management as a team, emphasizing group results.

   The Company implemented the Economic Value Added (EVA(R)) business
management system beginning in 1996 and continued to use this measurement
system in 2000, as the primary basis for the annual incentive bonus plan
discussed below. EVA is a method of measuring a company's financial performance
by taking its operating profit after taxes and subtracting a charge for the
capital employed to create the profit. EVA will be positive when a company's
return on capital exceeds its cost of capital.

   EVA is a registered trademark of Stern Stewart & Company.

Base Salary

   Effective January 1, 2000, the CEO's base salary was increased to $735,000,
a change of five percent over the 1998 level which was not changed in 1999.
Factors considered by the Committee in determining his 2000 salary included
analyses of the comparator group and the scope of his responsibilities. The
foregoing factors were utilized by our outside consultants in making their
recommendation to the Committee. The CEO's base salary was above the median of
the comparator group in 2000.

   Also effective January 1, 2000, base salary adjustments were made for all
other named executives. Salaries for these executives had last been adjusted in
July, 1998. All base salary adjustments utilized the same methodology cited
above.

Annual Incentive Bonus

   Incentive bonuses were based on two elements: (1) EVA performance of the
Company and (2) performance against personal objectives. The total bonus of the
CEO was determined using a weighting of 75% on EVA performance and 25% on
performance against personal objectives.

                                       9


   For 2000, the EVA performance element was determined using the Company's
actual EVA performance versus the predetermined target. EVA performance
exceeded the goal for 2000. The Company maintains a "bonus bank" for each
individual participating in the bonus plan. Only a predetermined portion of the
EVA performance award (plus a predetermined portion of the bonus bank balance,
if the bank balance is positive) is actually paid in a given year. For 2000,
the predetermined payout percent was 33% for the executive officers. If bonus
bank balances carried over from the prior year are negative, an executive
receives the predetermined payout percent of the declared award for the year in
question. The portion of the declared award not paid to the executive is
credited against the existing negative or positive bank balance to determine
the new ending bank balance. This positive or negative balance is held in the
bank. If the balance is positive, it will be available for payout over
subsequent years if EVA performance is sustained but it remains at risk, until
it is paid out. With performance below target, bank balances may become
negative, in which case, they must be offset and therefore will reduce future
awards. This banking feature imparts a longer term component to the plan,
serves to smooth out the payouts through economic cycles and provides a
retention element. The bank balance, if any, is paid upon retirement, death or
disability and may be paid upon termination of employment in certain other
events.

   The amount of the discretionary element of the award is determined by the
Compensation Committee and is not added to the bonus bank, but is paid out in
full for the year earned.

   The CEO's 2000 incentive payout was $437,842, made up of $292,842 for EVA
performance and $145,000 for performance against personal objectives. This
compares to a total annual incentive payout in 1999 of $137,500, made up
entirely of the discretionary award with no payout for EVA performance. His
ending 2000 EVA performance-related bank balance is $322,942, compared to a
negative $271,616 in 1999.

   The actual bonus awards for the Executive Vice President and the Senior Vice
President, Corporate Affairs were determined in a similar fashion, based on the
Company's EVA performance and performance toward their personal objectives with
weightings of 75% and 25% respectively. The other named executives, two
Division Presidents, each had their incentive awards based on a combination of
the Company's EVA and his Division's EVA performance (75% weighting) and their
personal objectives (25% weighting).

Long Term Incentive Award

   As explained above, the Compensation Committee determined the long term
incentive award opportunity for each named executive in early 2000. A long term
incentive plan in the form of stock option grants provides a direct linkage to
shareholder value. The CEO and other named executives received stock option
grants in 2000 with an option price set at the fair market value of Common
Stock on the date of the grant. These option grants vest one-third each year
beginning in 2001 and have a ten year term.

   Also in 2000, the CEO and other named executives received a special,
one-time grant of Performance Accelerated Vesting Stock Options. These options
have an exercise price equal to the common stock price on the day of the grant,
$18.97 per share. The objective of this special grant was to provide additional
incentive for the senior management team to improve the performance of the
business and accelerate a significant increase in shareholder value. These
options have a term of 120 months and vest in 119 months. They can vest early,
but only if the stock price increases to $28 per share or more for ten days in
any 30 calendar day period - an increase of almost fifty percent over the price
on the day of the grant.

(a) 1999 numbers include special performance bonuses related to work performed
    in connection with the spin-off of Arch Chemicals in the amounts of
    $150,000 for the CEO, $100,000 for the CFO and $75,000 for the Senior Vice
    President. Bonus payments to Messrs. Griffin, Ruggiero and Kosche for the
    EVA Performance of the Company were $0 for 1999.
(b) No amounts of "Other annual compensation" were paid to any named executive
    officer except for perquisites and other personal benefits, which for each
    executive officer did not exceed the lesser of $50,000 or 10% of such
    individual's salary plus bonus.
(c) As required by Securities and Exchange Commission rules, LTIP awards are
    reported in the year paid rather than in the year earned, because by their
    nature they do not reflect performance in one particular year and often are
    not fully determinable until paid. LTIP payouts in 1999 included retention
    units for 1989-1992 which had a six-year normal retention period which
    accelerated to payout in 1999 prior to the spin-off of Arch Chemicals.
(d) Amounts reported in this column for 2000 are comprised of the following

     Ruggiero at the time he joined the Company in August of 1995.
 (2) The Supplemental CEOP permits participants in the CEOP to make
     contributions, which Olin matches in amounts permitted by the CEOP but
     which would otherwise be in excess of those permitted by certain Internal
     Revenue Service limitations.
 (3) Under Olin's key executive insurance program, additional life insurance is
     provided and monthly payments are made to the spouse and dependent
     children of deceased participants.
 (4) The amount of the premium shown represents the full dollar amount of the
     premium Olin paid in 2000 for the whole life insurance and to fund the
     retiree death benefit. Such amounts also include retroactive premiums
     which Olin paid to cover a period of time during which some premiums were
     suspended due to the financial instability of the insurance carrier.
(e) Effective March 1, 2001, Joseph D. Rupp was elected Executive Vice
    President, Operations.

                              Stock Option Plans

   Under Olin's stock option plans, options to purchase shares of Common Stock
have been granted to key employees selected by the Compensation Committee. The
option price may not be less than the fair market value of Common Stock on the
date of grant and options may not be exercised later than ten years from such
date. Instead of requiring an optionee to pay cash, the Compensation Committee
may permit the delivery of Common Stock, valued at the fair market value on the
date of exercise, in payment for the exercise price of options. Except for
anti-dilution adjustments, options do not provide for repricing or adjustments
to the exercise price.

   The following table sets forth as to the individuals named in the summary
compensation table on page 11, information relating to options granted by Olin
from January 1, 2000 through December 31, 2000.

(a) Options for the five named individuals were awarded on January 27, 2000.
    Half of the grant consists of stock options which become exercisable in
    three equal annual increments, beginning on January 27, 2001. The other
    half of the grant consists of performance-accelerated vesting options which
    become exercisable on the earlier of December 27, 2009 or the tenth day (in
    any 30 calendar day period) upon which the average of the high and low per
    share sales prices of the common stock as reported on the consolidated
    transaction system for New York Stock Exchange issues is at or above
    $28.00.
(b) The exercise price of the options is equal to the fair market value of
    Common Stock on the date of grant.
(c) No gain to the optionees is possible without appreciation in the stock
    price which will benefit all shareholders commensurately. The dollar
    amounts under these columns are the result of calculations at the 5% and
    10% assumption rates set by the SEC and therefore are not intended to
    forecast possible future appreciation of Olin's stock price or to establish
    any present value of the options.
(d) Realizable values are computed based on the number of options which were
    granted in 2000 and which were still outstanding at year-end.

                          Corporate Performance Graph

   The Olin Peer Group consists of Georgia Gulf Corporation, Pioneer Company,
Brush Engineered Materials Inc., Chase Industries Inc., Mueller Industries,
Inc. and Wolverine Tube, Inc. The Olin Peer Group has been weighted in
accordance with market capitalization (closing stock price multiplied by the
number of shares outstanding) as of the beginning of each of the five years
covered by the performance graph. The weighted return for each year was
calculated by multiplying (a) the percentage that each corporation's market
capitalization represented of the total market capitalization for all
corporations in the Olin Peer Group for such year by (b) the total shareholder
return for that corporation for such year.

Executive Agreements

   As of December 31, 2000 each of the executive officers named in the table on
page 11 and five other employees had agreements with Olin which provide, among
other things, that in the event of a covered termination of employment (which
could include, among other things, termination of employment other than for
cause and termination at the election of the individual to leave Olin under
certain circumstances), the individual will receive a lump sum severance
payment from Olin equal to 12 months' salary plus the greater of (a) the
average incentive compensation award paid from Olin during the three years
preceding the termination or (b) the then standard annual incentive
compensation award, less any amounts payable under existing disability plans of
Olin, in lieu of other Olin severance benefits. In the event that a ''Change in
Control'' of Olin occurs, and there is a covered termination, the individual
will receive three times the severance payment. Pension credit and insurance
coverage would be afforded for the period reflected in the severance payment,
and in certain cases, insurance coverage will be extended beyond such period.
The agreements also provide for certain outplacement services. The agreements
will expire on September 30, 2002, unless prior to that date there is a
''Change in Control'' of Olin, in which event they will expire on the later of
September 30, 2002 or three years following the date of the ''Change in
Control.'' A ''Change in Control'' would occur if Olin ceases to be publicly
owned; 20% or more of its voting stock is acquired by others (other than an
Olin employee benefit plan); the incumbent directors and their designated
successors cease over a two-year period to constitute a majority of the Board;
or all or substantially all of Olin's business is disposed of in a transaction
in which Olin is not the surviving corporation or Olin combines with another
company and is the surviving corporation (unless Olin shareholders following
the transaction own more than 50% of the voting stock or other ownership
interest of the surviving entity or combined company). Each agreement provides
that the individual agrees to remain in Olin's employ for six months after a
''Potential Change in Control'' of Olin has occurred or until a Change in
Control occurs, provided that the individual retains substantially the same
position as before the Potential Change in Control, whichever occurs earlier.
The agreements provide that payments made thereunder or under any change in
control provision of an Olin compensation or benefit plan which are subject to
''excess parachute payment'' tax will be increased so that the individual will
receive a net payment equal to that which would have been received if such tax
did not apply. Certain of Olin's benefit and compensation plans, including its
EVA annual incentive bonus plan, also contain ''change-in-control'' provisions.

   In addition, three of the named executive officers in the table on page 11
and two other executives have retention agreements that provide them with
decreasing lump-sum payments for salary and bonus as well as continuation of
other benefits through the end of 2001, in the event of a covered termination.
If the covered termination is the result of the executive's resignation for one
of the enumerated reasons, he or she must provide at least 90 days' notice. The
agreements terminate upon a Change in Control as defined above. In no event may
an executive receive (under both agreements) an aggregate sum more than the
maximum benefit under the Change in Control agreements described above.

Retirement Benefits

   The Olin Corporation Employees Pension Plan, together with two supplementary
plans (collectively, the ''Pension Plan''), provide for fixed benefits upon
retirement. The normal retirement age is 65, but early retirement is available
after age 55 with at least 10 years of service, at a reduced percentage of the
normal retirement allowance (100% is payable if early retirement is at age 62).
Directors who are not also employees of Olin are not eligible to participate in
the Pension Plan. The Olin Corporation Employees Pension Plan is a
tax-qualified plan, and benefits are payable only with respect to current
compensation. Under one of the supplementary plans mentioned above, Olin pays a
supplemental pension, based on the formula described in the next paragraph, on
deferred compensation (including deferred incentive compensation). Under the
other supplementary plan, Olin

                                      15


will pay employees affected by the limitations imposed by the Internal Revenue
Code on qualified plans a supplemental pension in an annual amount equal to the
reduction in pensions resulting from such limitations.

   ''Compensation'' for purposes of the Pension Plan represents average cash
compensation per year (salary and bonus shown in the summary compensation table
on page 11) received for the highest three years during the ten years up to and
including the year in which an employee retires. The normal retirement
allowance is 1.5% of ''Compensation'' as so defined multiplied by the number of
years of benefit service, less a percentage of the employee's primary Social
Security benefit based on years of service, not to exceed 50% of such Social
Security benefit.

   Under the Senior Executive Pension Plan (the ''Senior Plan''), Olin will pay
retirement benefits to certain senior executives upon their retirement after
age 55, with reduced benefits if retirement is prior to age 62. Under the
Senior Plan, the maximum benefit will be 50% of ''Compensation'' (as defined
above), less payments from the Pension Plan, any other Olin pension, pension
benefits from other employers, and Social Security benefits. Subject to the
above limitations, benefits under the Senior Plan will accrue at the rate of 3%
for each year of service in a senior executive position, reduced by payments
under the Pension Plan which accrued during the period the employee was in the
Senior Plan and by 50% of the employee's primary social security benefit. The
Senior Plan will also provide benefits to the executive's surviving spouse
equal to 50% of the executive's benefits. Payment of benefits under the Senior
Plan is subject to satisfaction of its service requirements and other plan
provisions regarding suspension of benefit accruals and cessation of benefits.
The Senior Plan and the other two plans provide that unless the participant
elects installment payments, the participant will receive benefits under these
plans in a lump sum upon retirement if the lump sum would exceed $100,000. The
Compensation Committee may remove a participant from the Senior Plan for cause
as defined in such plan.

   The Olin Corporation Employees Pension Plan provides that if, within three
years following a ''Change in Control'' of Olin, any corporate action is taken
or filing made in contemplation of, among other things, a plan termination or
merger or other transfer of assets or liabilities of the plan, and such
termination, merger or other event thereafter takes place, plan benefits would
automatically be increased for affected participants (and retired participants)
to absorb any plan surplus.

   The Senior Plan and the other two plans mentioned above provide that in the
event of a ''Change in Control,'' Olin will pay each participant a lump sum
amount sufficient to purchase an annuity which (together with any monthly
payment provided under trust arrangements or other annuities established or
purchased by Olin to make payments under such plan) will provide the
participant with the same monthly after-tax benefit as the participant would
have received under the plan, based on benefits accrued thereunder to the date
of the ''Change in Control.'' The agreements described under ''Executive
Agreements'' above provide that an executive officer who is less than age 55 at
the time of a ''Change in Control'' will, for purposes of calculating the above
lump sum payment under the Senior Plan, be treated as if he or she had retired
at age 55, with the lump sum payment being calculated on the basis of service
to the date of a ''Change in Control.''

                                      16


   The following table shows the maximum combined amounts payable annually on
normal retirement under the Pension Plan and Senior Plan. Such amounts will be
reduced by Social Security benefits and the other offsets described above.

                         Report of the Audit Committee

   The Audit Committee held four meetings during 2000. The meetings were
designed to facilitate and encourage private communication between the
Committee and the internal auditors and the Company's independent public
accountants, KPMG LLP.

   The Committee consists of three directors, all of whom are independent
directors under NYSE listing standards.The Committee acts under a written
Charter first adopted by the Board of Directors in 1997. A copy of the current
Audit Committee Charter, which was updated in 2000, is reproduced in Appendix A
to this proxy statement.

   The Committee has reviewed and discussed the audited financial statements
for fiscal year 2000 with Management and with the independent auditors.
Specifically, the Committee has discussed with the independent auditors the
matters required to be discussed by SAS 61 (Codification of Statements on
Auditing Standards, AU Section 380), which includes, among other things:

    .  methods used to account for significant unusual transactions;

    .  the effect of significant accounting policies in controversial or
       emerging areas for which there is a lack of authoritative guidance or
       consensus;

                                      17


    .  the process used by Management in formulating particularly sensitive
       accounting estimates and the basis for the auditor's conclusions
       regarding the reasonableness of those estimates; and

    .  disagreements with Management over the application of accounting
       principles, the basis for Management's accounting estimates, and the
       disclosures in the financial statements.

   In addition, the Committee has received the written disclosures and the
letter from the Company's independent accountants, KPMG LLP, required by
Independence Standards Board Standard No. 1, INDEPENDENCE DISCUSSIONS WITH
AUDIT COMMITTEES and discussed with KPMG the issue of its independence from
Olin. The Committee also reviewed the fees paid to KPMG during 2000 to ensure
that none of the work performed was incompatible with maintaining KPMG's
independence.

   Based on the Committee's discussion with Management and the independent
accountants and the Committee's review of the representation of Management and
the report of the independent accountants to the Committee, the Committee
recommended that the Board of Directors include the audited consolidated
financial statements in the Corporation's Annual Report on Form 10-K for the
year ended December 31, 2000 filed with the Securities and Exchange Commission.

to assist the Board in fulfilling its oversight responsibilities. The charge of
the Committee is to:

   systems of internal control covering the areas of finance, accounting,

   (EHS&T) and legal compliance.

 .  Monitor the independence and performance of the Corporation's independent
   auditors and internal audit and EHS&T audit functions.

 .  Provide an avenue for communication between the Board of Directors and
   Management, the independent auditors and the internal audit and EHS&T audit
   functions.

   The Committee has direct access to the independent auditors as well as
anyone else in the organization. In addition, the Committee may use both
internal and external resources and advisors, as it deems appropriate in
carrying out its duties. The Chairman of the Board shall provide the Committee
with all of the resources, both internal and external, which the Committee
deems necessary or advisable to meet its duties and responsibilities and carry
out its function.

Membership and Meetings

   The Committee will consist of no less than three Directors, all of whom are
independent outside Directors, free from any relationship with the Corporation
that would interfere with their independent judgement. In all cases membership
on the Committee will comply with the rules of the New York Stock Exchange

accounting and be able to read and understand financial statements. In
addition, at least one member shall have accounting or related financial
management expertise as defined by the NYSE rules.

frequently as circumstances dictate. Regular meetings of the Committee will be
at times during the year as approved by the Committee. The Audit Committee

conclusions and recommendations to the Board of Directors at the next meeting.

   meeting proxy statement in accordance with SEC regulations.

   independent auditors all significant relationships they have with the
