                                                                 March 14, 2002

         Dear Olin Shareholder:

            We cordially invite you to attend our 2002 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 2002 annual meeting.

            This year, we have prepared the proxy statement in a format that we
         hope is easier to understand. The Securities and Exchange Commission
         encourages companies to write documents for investors in plain
         English, and we support this effort. We hope you like the new format,
         and we welcome your comments.

            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 91% 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,

                                          /s/ DONALD GRIFFIN
                                                Donald W. Griffin
                                               Chairman of the Board

                            YOUR VOTE IS IMPORTANT

 We urge you to promptly vote your shares on the Internet, by telephone or by
   completing, signing, dating and returning your proxy card in the enclosed
                                   envelope.

   If you want to vote in person at the annual meeting, and you own your Olin
shares through a custodian, broker or other agent, you must obtain a proxy from
that party in their capacity as owner of record for your shares and bring the
proxy to the annual meeting.

How are votes counted?

   If you specifically mark your 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 your proxy card but do not
specifically mark it with your instructions as to how you want to vote, your
proxy will be voted for the election of the Directors, and in favor of the
ratification of KPMG LLP as independent auditors for 2002.

   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.

Can I change my vote?

   Yes. Even if you submit a proxy card with your voting instructions, you may
revoke or change it in person at the meeting any time before it is exercised or
in a timely manner before the expiration of the voting deadlines by:

   .  submitting another written proxy with a later date,

   .  casting a new vote on the Internet or by telephone,

   .  sending a written notice of the change in your voting instructions to the
      Secretary if received before the annual meeting, or

   Shares represented by proxies on the enclosed proxy card will be counted in
the vote at the annual meeting if we receive your proxy card by April 24, 2002.
Proxies submitted by the Internet or by telephone will be counted in the vote
only if they are received by 4:00 p.m., Eastern Daylight time on April 24, 2002.

How do I vote my shares held in the Olin Contributing Employee Ownership Plan
or the Arch Chemicals, Inc. Contributing Employee Ownership Plan?

common stock fund of the Olin Corporation Contributing Employee Ownership Plan

or both of these plans as the CEOP. JPMorgan Chase Bank, as the Trustee of the
CEOP, holds all of those shares. If you are a participant in the CEOP, you may
instruct JPMorgan Chase Bank how to vote shares of common stock credited to you
by indicating your instructions on your proxy card and returning it to us or by
voting on the Internet or telephone. JPMorgan Chase Bank will vote shares of
common stock held in the CEOP for which it does not receive voting
instructions, or which are not credited to participants' accounts, in the same
manner proportionately as it votes the shares of common stock for which they do
receive instructions.

                ITEM 1--PROPOSAL FOR THE ELECTION OF DIRECTORS

Who are the individuals nominated by the Board to serve as Directors?

   The Board of Directors is divided into three classes. Each class has a term
of office for three years, and the term of each class ends in a different year.
The Board has nominated three persons, each of whom is listed under "Nominees
for Three-Year Terms Expiring in 2005", for election as Class II Directors to
serve until the 2005 annual meeting of shareholders and until their successors
have been elected. Two of those directors, G. Jackson Ratcliffe, Jr. and
Richard M. Rompala, are currently serving as Class II Directors. The third,
Joseph D. Rupp, was elected by the Board of Directors pursuant to Olin's
By-Laws as a new Class III director on January 1, 2002. Olin's By-Laws require
that any director elected by the Board of Directors shall serve only until the
next election of Directors by the shareholders. The Board has nominated Mr.
Rupp for election by the shareholders as a Class II Director. The Board has
also nominated Donald W. Griffin for election as a Class III Director with a
term expiring in 2003. The terms of the other Directors will continue after the
annual meeting as indicated below.

   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.

            ADDITIONAL INFORMATION REGARDING THE BOARD OF DIRECTORS

How many meetings did Board members attend?

   During 2001, the Board held six meetings. Each of the current Directors
attended 100% of the meetings of the Board and committees of the Board on which
they served.

What are the committees of the Board?

   The Audit Committee, which held five meetings during 2001, advises the Board
on internal and external audit matters affecting us. The audit committee:

     .    recommends the appointment of our independent auditors, reviews with
          such auditors the scope and results of their examination of our
          financial statements and any investigations and surveys by such
          auditors;

     .    reviews its charter annually and publishes the charter in the annual
          meeting proxy statement in accordance with SEC regulations;

     .    reviews our annual audited financial statements before filing or
          distribution;

     .    reviews with management and our independent auditors, the interim
          financial results and related press releases before issuance to the

are used to compensate the chief executive officer and other senior executives.
The compensation committee:

     .    approves the salary plans for senior executives 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;

          long-term incentive plans;

          proxy statement;

     .    approves executive and change-in-control agreements;

     .    approves and adopts new tax-qualified and non-qualified pension plans,
          approves terminations of tax-qualified and non-qualified pension

     .    advises the Board on the compensation of directors.

                                      9



   The Directors and Corporate Governance Committee, which held four meetings
during 2001, assists the Board in fulfilling its responsibility to our
shareholders relating to the selection and nomination of officers and
Directors. 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;

     .  annually evaluates the performance of the chief executive officer;

     .  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;

     .  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;

     .  reviews and makes recommendations to the Board regarding the
        composition, duties and responsibilities of various Board committees;

     .  reviews and advises the Board on such matters as protection against
        liability and indemnification; and

     .  reports periodically to the Board on the performance of the Board itself
        as a whole.

   The Executive Committee meets as needed in accordance with our By-laws.
Between meetings of the Board, the executive committee may exercise all the
power and authority of the Board (including authority and power over our
financial affairs) except for matters reserved to the full Board by Virginia
law and matters for which the Board gives specific directions. During 2001,
this committee held no meetings.

How are the Directors compensated?

   During 2001, we compensated each non-employee Director on the Board with:

     .  an annual retainer of $30,000, of which $25,000 was paid or credited in
        the form of shares of common stock.

     .  shares of common stock with an aggregate fair market value equal to
        $24,000, rounded to the nearest 100 shares.

     .  a fee of $1,500 for each meeting of the Board and for each meeting of a
        committee of the Board attended by a committee member.

     .  a $5,000 annual fee for committee chairs.

     .  reimbursement for expenses incurred in the performance of their duties
        as Directors.

     .  a 100% matching contribution to an eligible institution for gifts made
        by a Director (50% for gifts made after November 1, 2001) to such
        institution, but the matching gift plan is limited to $5,000 per
        Director per year.

     .  insurance coverage while on Company business under our business travel
        accident insurance policy.

     .  a special one-time fee of $6,000, for significant succession planning
        work outside the normal director duties during 2001.

                                      10



   Directors may elect to receive common stock instead of cash for any portion
of their cash compensation and to defer any stock or cash payments. 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. If there is a "Change in Control" as
defined in the 1997 Stock Plan for Non-Employee Directors, (what we refer to as
the Directors Plan) the balance of any deferred account is paid to the
Directors.

   The Directors' Plan also holds, as ''phantom'' shares, the shares of common
stock of Arch Chemicals, Inc. issued to any Director as a dividend distribution
on their shares of Olin common stock held in their Directors' Plan accounts at
the time of the spin-off of Arch Chemicals, Inc. Those Arch Chemicals, Inc.
phantom shares are payable only in cash, unless a Director elects to transfer
the Arch Chemicals, Inc. phantom shares into their Olin common stock accounts.

   Directors who are also employees of Olin do not receive any extra
compensation for their services as Directors.

                                      11

                            EXECUTIVE COMPENSATION

    Report of the Compensation Committee on Executive Compensation for 2001

Compensation Philosophy

   Olin designs its executive compensation policies and program based on
specific objectives:

     .  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.

To accomplish these objectives, the Company emphasizes variable compensation,
an emphasis consistent with competitive practice.

Executive Compensation Program as Administered in 2001

   The compensation committee establishes total compensation opportunities (and
the three individual components) for the CEO and other named executive officers
targeted to the median of a group of more than 600 companies that represent
general U.S. industry, referred to as the "comparator group."

   Independent executive compensation consultants provide the committee with an
annual assessment of the Company's relative position within this comparator
group. The total target compensation opportunity for each executive includes
the following components:

     .  annual base salary

     .  annual incentive award opportunity

     .  long term incentive award

Once the committee determines the total targeted compensation opportunity for
the CEO and the other named executive officers, the committee determines the
appropriate mix of these three components, again with the advice of outside
executive compensation consultants, using the competitive analysis.

   The Company implemented the Economic Value Added (EVA/(R)/) business
management system beginning in 1996 and continued to use this measurement
system in 2001, as the primary basis for the annual incentive plan discussed
below./(1)/ 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.

Base Salary

   Effective January 1, 2001, the CEO's base salary was increased to $760,000,
3.4% over the 2000 level. Factors utilized by the committee in determining the
CEO's 2001 salary included analyses of the comparator group and the scope of
his responsibilities. The CEO's base salary was above the median of the
comparator group in 2001.

   The compensation committee used the same methodology to determine base
salary adjustments for the other four named executive officers.

                                      14



Annual Incentive Award

   Olin makes incentive awards based on two elements: (1) Olin's EVA
performance and (2) performance against personal and team objectives. The CEO's
total award was determined using a weighting of 75% on EVA performance and 25%
on performance against personal and team objectives. For 2001, the EVA
performance element compares Olin's actual EVA performance against a
predetermined target. EVA performance was below the target for 2001.

   The Company maintains a "bonus bank" account for each individual
participating in the award plan. We pay a predetermined portion of the annual
EVA performance award, if any, (plus a predetermined portion of the bonus bank
balance, if the bank balance is positive) in a given year. For 2001, the
predetermined payout percent was 33% for the executive officers. 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.

   With performance below target, bank balances may become negative, in which
case, they must be offset and therefore will reduce future awards. If bonus
bank balances carried over from the prior year are negative, an executive
receives the predetermined payout percent of the declared EVA 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.

   The discretionary portion 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 2001 incentive payout was $150,000, which represents his targeted
discretionary award for performance against personal and team objectives. He
received no payout for EVA performance. This compares to a total annual
incentive payout in 2000 of $437,842, made up of a $292,842 payout for EVA
performance and an award of $145,000 for performance against personal and team
objectives. His ending 2001 EVA performance-related bank balance is a negative
$284,558, compared to a positive balance of $322,942 in 2000.

   The actual awards for the Executive Vice President, Operations, the
Executive Vice President & Chief Financial Officer and the Senior Vice
President, Corporate Affairs, were determined in a similar fashion, with 75%
based on the Company's EVA performance and 25% based on performance toward
their personal and team objectives. The award for the other named executive
officer, a Division President, was based on a combination of the Company's EVA
and his Divisions' EVA performance (75% weighting) and his personal and team
objectives (25% weighting).

Long Term Incentive Award

   The compensation committee determined the long term incentive award
opportunity for each named executive officer in early 2001, based on the
competitive analysis described above. Under the 2001 long term incentive plan,
stock options represent one-half of the aggregate value of the long term
incentive award opportunity, and performance share awards make up the other
half.

   In 2001, Olin made changes in the method used to determine the grant size
for stock options. The sum of all of the option grants determines the aggregate
pool of options. This pool increases or decreases depending on Olin's trailing
three-year total shareholder return. Total shareholder return, or TSR,
represents the increase in the fair market value of Olin common stock over the
relevant period,

                                      15



including reinvestment of dividends, as calculated for the Performance Graph on
page 21. The option grant pool increases by 25% when Olin's TSR falls within
the top third relative to the TSR for companies in the S&P MidCap 400. The
option grant pool shrinks by 25% when Olin's TSR falls within the bottom third
relative to the TSR for companies in the S&P MidCap 400. Olin reduced its 2001
stock option grant pool by 25%, because Olin's trailing three-year TSR fell in
the bottom third of the companies in the S&P MidCap 400.

   The CEO and other named executive officers received stock option grants in
2001. The option price was set at the fair market value of common stock on the
date of the grant, and the options have a ten-year term. The CEO's options vest
on April 1, 2002, and the remaining option grants vest one-third each year
beginning in 2002. We also accelerated the vesting of Mr. Griffin's stock
options for 66,640 shares from the originally scheduled vesting date of January
27, 2003 to April 30, 2002. This modification did not result in any charge to
our earnings, as the exercise price for the options of $18.97 per share is
above the market price for our common stock.

   Individual standard option grant sizes are fixed by competitive analyses.
Actual grants made to individuals may be increased or decreased by up to 25% by
this committee (or the CEO for non-officers). The total of all adjusted grants
may not exceed the aggregate pool of available options for the year.

   The other half of the individual long term incentive requirement takes the
form of performance shares, with the number of performance shares based on the
competitive analysis and the price of Olin common stock at the time of the
grant. At the end of a three-year performance cycle, participants receive a
performance share award denominated in shares of Olin common stock, paid half
in shares of Olin common stock and half in cash, based on Olin's average annual
return on capital in relation to the average annual return on capital among the
S&P MidCap 400 companies. Return on capital, or ROC, means Olin's consolidated
net income, plus after-tax interest expense and the after-tax effect of any
special charge or gain, and any cumulative effect of a change in accounting,
divided by Olin's average consolidated total assets less total non-interest
bearing liabilities. The award may increase by as much as 50% if Olin's average
annual ROC falls in the top 20% of the S&P MidCap 400 performance and may fall
to 25% if Olin's performance drops to the bottom 20% of the S&P MidCap 400
performance. The CEO and other named executive officers received grants of
performance shares in 2001. The terms of Mr. Griffin's 2001 performance share
grant were modified to provide him with the benefits of all such performance
shares (rather than a pro rata portion) at such time as shares are issued to
other executive officers in accordance with the terms of the 2001 Performance
Share Program.

   Section 162(m) of the Internal Revenue Code denies Olin a deduction for
compensation paid to a named executive officer in a taxable year, to the extent
his compensation that does not meet the definition of "performance-based
compensation" exceeds $1,000,000. Olin structures the stock options, and
significant portions of the remaining long term incentive and of the annual
incentive, to meet the criteria for performance-based compensation. It is
possible, however, that the portions of these awards that do not qualify as
"performance-based compensation," when combined with salary and other forms of
compensation Olin pays to a named executive officer, may exceed this limitation
in any particular year.

--------
(a)Effective January 1, 2002, Mr. Rupp became President and Chief Executive
   Officer. Mr. Griffin remains as Chairman of the Board.
(b)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.
   We did not make any bonus payments to Messrs. Griffin, Ruggiero or Kosche
   for the Company's EVA Performance for 1999 and 2001.
(c)We did not pay "Other annual compensation" 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.
(d)As required by Securities and Exchange Commission rules, we report LTIP
   awards 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.
(e)Amounts reported in this column for 2001 are comprised of the following
   items:

        (1)Olin employees may exercise their options for shares of Arch
           Chemicals, Inc. common stock (issued in the 1999 spin-off of Arch
           Chemicals) for either a cash payment or for Arch Chemicals common
           stock. Olin pays the difference between the option exercise price
           and the fair market value of Arch Chemicals common stock at the time
           of exercise to the employee if he or she elects to take cash, or to
           Arch, which then issues the appropriate number of shares to the
           employee, if the employee elects to take stock.
        (2)Under the Supplemental CEOP, CEOP participants whose contributions
           are limited under certain IRS regulations, may make tax deferred
           contributions as would otherwise be permitted in the CEOP. We match
           Supplemental CEOP contributions, as we would under the CEOP. The
           amounts of our matching contributions made on behalf of the
           executives are shown.
        (3)The key executive life insurance program offers executives the
           choice between additional life insurance or monthly income benefits
           for their spouse and children, if they die while working for Olin.
           We fund these benefits through life insurance and the premiums we
           paid are shown.
        (4)Represents the total amount of the premiums we paid in 2001 for life
           insurance and to fund the retiree death benefits.

                              Stock Option Plans

   We grant to key employees, selected by the compensation committee, options
to purchase shares of common stock. The option price must be at least the fair
market value of the common stock on the date of the grant and the 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 an optionee to pay
the exercise price of the options with common stock, valued at the market price
on the date of exercise. Except for anti-dilution adjustments, options do not
provide for repricing or other adjustments to the exercise price.

   This table provides information about stock options we granted in 2001 to
the individuals named in the Summary Compensation Table on page 17.

--------
(a)We awarded stock options to the five named individuals effective February 8,
   2001. The options granted to Mr. Griffin become exercisable on April 1,
   2002. The remaining options become exercisable in three equal annual
   increments, beginning on February 8, 2002.
(b)The per share exercise price of the options is equal to the fair market
   value of common stock on the grant dates (calculated on a weighted average
   basis).
(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 our stock price or to establish any present value of
   the options.
(d)Realizable values are computed based on the number of options granted in
   2001 and still outstanding at year-end.
(e)The expiration dates of options granted during 2001 are February 7, 2011,
   March 1, 2011, and August 8, 2011.

                               Performance Graph

   This graph compares the total shareholder return on our common stock with
the total return on the S&P Midcap 400 and our peer group for the five-year
period from December 31, 1996 through December 31, 2001. The cumulative return
includes reinvestment of dividends.

   Our peer group consists of Georgia Gulf Corporation, Brush Engineered
Materials Inc., Chase Industries Inc., Mueller Industries, Inc. and Wolverine
Tube, Inc. Our Peer Group is 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. We
calculated the weighted return for each year by multiplying (a) the percentage
that each corporation's market capitalization represented of the total market
capitalization for all corporations in our Peer Group for such year by (b) the
total shareholder return for that corporation for such year. Our Peer Group no
longer includes Pioneer Companies, Inc., as Pioneer's previously outstanding
common stock was cancelled in 2001 as part of Pioneer's Chapter 11 bankruptcy
proceedings in the United States (and parallel proceedings in Canada).

                             EXECUTIVE AGREEMENTS

   As of December 31, 2001, Olin had compensation agreements with the executive
officers named in the table on page 17 and five other officers. These
agreements provide, among other things, that the officer will receive a payment
from Olin if the individual's employment is terminated (other than for cause),
or the employee elects to leave Olin under certain circumstances. The payment
includes a lump sum severance payment equal to 12 months' salary plus the
greater of:

     .    the average incentive compensation award paid by Olin during the three
          years before the termination, or

     .    the standard annual incentive compensation award, less any amounts
          payable under existing disability plans of Olin, instead of other Olin
          severance benefits.

Olin provides pension credit and insurance coverage for twelve months, and in
certain cases, beyond such period. The agreements also provide for outplacement
services.

   If a "Change in Control" of Olin occurs, the agreements provide that the
officer will receive a lump sum severance payment equal to three times the
severance payment described above. A "Change in Control" occurs 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 current Directors and their designated successors become a
          minority of the Board over a two-year period;

     .    substantially all of our business is disposed of in a transaction in
          which Olin is not the surviving corporation; or

     .    Olin merges with another company and is the surviving corporation
          (unless Olin shareholders own more than 50% of the voting stock or
          other ownership interest of the combined company).

   In the event of a "Change in Control" of Olin, these executive agreements
require qualified individuals to continue to work for a period of six months
after an announcement or a contract providing for a potential "Change of
Control," provided that the individual retains substantially the same position
as before the potential "Change in Control." These executive agreements expire
on September 30, 2002, (or, if a "Change in Control" occurs before that date,
three years following the "Change in Control"). These executive agreements
also provide that any payments made under any "Change in Control" provision in
any compensation or benefit plan of Olin subject to the "excess parachute
payment" tax will be increased so that the executive will receive the same net
payment as 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.

                                      22



                              RETIREMENT BENEFITS

Qualified Pension Plan for Employees

   We provide fixed retirement benefits through a tax qualified pension plan
and two non-qualified plans described below. The normal retirement age is 65,
but early retirement is available after age 55 with at least 10 years of
service. (If early retirement is before age 62, the employee receives reduced
benefits.) The pension benefits are calculated based on the average cash
compensation per year (salary and bonus shown in the Summary Compensation Table
on page 17) for the highest three years during the ten years before and
including the year in which an employee retires. The normal retirement
allowance is 1.5% of the employee's average compensation multiplied by the
number of years of 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).

   When the employee qualifies and elects to retire, the benefits of the
qualified plan will be paid in monthly installments, unless the present value
of the benefit is less than $5,000. The qualified pension plan, called 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 increase for affected participants (and retired participants) to
absorb any surplus plan assets.

Non-Qualified Supplemental Employee Pension Plan

   Under this non-qualified supplemental pension plan, we pay a supplemental
pension based on the formula described above on deferred compensation,
including deferred incentive compensation.

   The non-qualified supplemental pension plan also provides additional pension
benefits to highly compensated employees, whose benefits from qualified plans
are limited by the Internal Revenue Code. This plan provides for the payment of
supplemental pension benefits equal to the reduction in the qualified plan
benefit resulting from the IRS limitations.

   The non-qualified supplemental pension plan provides that unless the
executive elects installment payments, the executive will receive benefits
under the plan in a lump sum, provided the lump sum exceeds $100,000.

   In the event of a "Change in Control", we will pay each eligible employee a
lump sum amount sufficient to purchase an annuity which will provide the same
monthly after tax benefit as the employee would have received under the plan
based on benefits accrued as of the date of the Change in Control. The lump sum
payment will be reduced to take into consideration monthly payments provided
under trust arrangements or other annuities we establish or purchase to make
payments under this plan.

Senior Executive Pension Plan

   Our Senior Executive Pension Plan provides additional pension benefits for
senior executives. Under this plan, we pay pension benefits to certain senior
executives when they retire after age 55 (with reduced benefits if they retire
before age 62). The benefits are based on the average cash compensation per
year (salary and bonus shown in the Summary Compensation Table on page 17) for
the highest three years during the ten years including the year in which an
executive retires. The benefits equal 3% of the executive's average
compensation multiplied by the number of years of service in a senior executive
position, reduced by pension benefits that accrued under our qualified and
non-qualified plans for the period of time credited under the Senior Executive
Pension Plan, and

                                      23



further reduced by 50% of employee's primary Social Security benefit. The
maximum benefit payable is 50% of the employee's average compensation reduced
by amounts payable from our qualified and non-qualified plans and certain
adjustments set forth in the plan documents, if applicable. The Senior
Executive Pension Plan also provides benefits to an executive's surviving
spouse equal to 50% of the executive's benefits.

   To receive benefits under the Senior Executive Pension Plan, an executive
must meet the service requirements and other plan provisions regarding
suspension of benefit accruals and cessation of benefits. Even if the benefits
have accrued, the compensation committee may remove a participant from the
Senior Executive Pension Plan for cause.

   The Senior Executive Pension Plan provides that unless the executive elects
installment payments, the executive will receive benefits under the plan in a
lump sum payment upon retirement as long as the lump sum would exceed $100,000.
However, in the event of a "Change in Control," the plan will pay qualified
executives a lump sum amount sufficient to purchase an annuity which will
provide the same after-tax benefit. In addition, the agreements described above
under "Executive Agreements" provide that an executive officer who is less
than age 55 at the time of a "Change in Control," will be treated as if he or
she had retired at age 55, and the lump sum payment will be calculated based on
the years of service at the date of a "Change in Control."

   The following table shows the maximum amount of retirement benefits annually
payable under the qualified pension plan, the non-qualified supplemental
pension plan and the senior executive pension plan. These amounts will be
reduced by Social Security benefits and other offsets described above.

                         Report of the Audit Committee

   The audit committee held five meetings during 2001. The meetings were
designed to facilitate and encourage private communication between the audit
committee and the internal auditors and our independent public accountants,
KPMG LLP.

   The audit committee consists of three Directors, all of whom meet the audit
committee member requirements under NYSE listing standards. The audit committee
acts under a written Charter adopted by the Board of Directors in 1997, which
is reviewed annually and was last updated in 2000.

   The audit committee reviewed and discussed the audited financial statements
for fiscal year 2001 with management and the independent auditors.
Specifically, the audit 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 include, among other things:

     .    methods Olin used to account for significant and unusual transactions;

     .    the effect of important accounting policies in controversial or
          emerging areas for which there is no authoritative guidance;

     .    the process management used to formulate sensitive accounting
          estimates and the auditor's conclusions regarding the reasonableness
          of those accounting estimates; and

     .    disagreements, if any, 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 audit committee received the written disclosures and a
letter from our independent accountants, KPMG LLP, 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. The audit committee also reviewed the fees paid to KPMG during 2001 to
ensure that all of the work performed was compatible with maintaining KPMG's
independence.

   Based on the audit committee's discussion with management and the
independent accountants and the audit committee's review of management and the
report of the independent accountants, 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, 2001 filed
with the Securities and Exchange Commission.

Who has the Board appointed as independent auditors for 2002?

   The Board has appointed the firm of KPMG LLP as our independent auditors for
the year 2002. The audit committee recommended the appointment of KPMG.

Is a shareholder vote required to approve Olin's independent auditors?

   The law and our By-laws do not require us to submit this matter to the
shareholders at the annual meeting. The Board chose to submit it to the
shareholders to ascertain their views. If shareholders do not ratify their
appointment at the annual meeting, the Board of Directors intends to reconsider
its appointment of KPMG LLP as independent auditors.

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

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

How many votes are required to approve the appointment of KPMG LLP as
independent auditors for 2002?

   To approve the appointment of KPMG LLP as independent auditors for 2002, the
votes cast in favor of KPMG LLP must exceed the votes cast in opposition to
KPMG LLP. Abstentions and shares held in street name that are not voted will
not be included in determining the number of votes cast.

How does the Board recommend you vote?

   The Board recommends that you vote FOR the ratification of the appointment
of KPMG LLP as our independent auditors for 2002.

                                          By Order of the Board of Directors:
