                OLIN CORPORATION AND CONSOLIDATED SUBSIDIARIES
                    NOTES TO CONDENSED FINANCIAL STATEMENTS

1. The condensed financial statements included herein have been prepared by the
   company, without audit, pursuant to the rules and regulations of the
   Securities and Exchange Commission and, in the opinion of the company,
   reflect all adjustments (consisting only of normal accruals) which are
   necessary to present fairly the results for interim periods.  Certain
   information and footnote disclosures normally included in financial
   statements prepared in accordance with generally accepted accounting
   principles have been condensed or omitted pursuant to such rules and
   regulations; however, the company believes that the disclosures are adequate
   to make the information presented not misleading.  It is suggested that these
   condensed financial statements be read in conjunction with the financial
   statements, accounting policies and the notes thereto and management's
   discussion and analysis of financial condition and results of operations
   included in the company's Annual Report on Form 10-K for the year ended
   December 31, 1997.

2. Inventory consists of the following:

   Inventories are valued principally by the dollar value last-in, first-out
   (LIFO) method of inventory accounting; in aggregate, such valuations are not
   in excess of market. Elements of costs in inventories include raw material,
   direct labor and manufacturing overhead. Inventories under the LIFO method
   are based on annual determination of quantities and costs as of the year-end;
   therefore, the condensed financial statements at March 31, 1998, reflect
   certain estimates relating to inventory quantities and costs at December 31,
   1998.

3. Basic earnings per share are computed by dividing net income by the weighted
   average number of common shares outstanding. Diluted earnings per share
   reflect the dilutive effect of stock options.

4. The company is party to various governmental and private environmental
   actions associated with waste disposal sites and manufacturing facilities.
   Environmental provisions charged to income amounted to $4 million for the
   three months ended March 31, 1998 and 1997. Charges to income for
   investigatory and remedial efforts were material to operating results in 1997
   and may be material to operating results in 1998. The consolidated balance
   sheets include reserves for future environmental expenditures to investigate
   and remediate known sites amounting to $136 million at March 31, 1998 and
   December 31, 1997, of which $106 million was classified as other noncurrent
   liabilities.

   Environmental exposures are difficult to assess for numerous reasons,
   including the identification of new sites, developments at sites resulting
   from investigatory studies, advances in technology, changes in environmental
   laws and regulations and their application, the scarcity of reliable data
   pertaining to identified sites, the difficulty in assessing the involvement
   and financial capability of other potentially responsible parties and the
   company's ability to obtain contributions from other parties and the length
   of time over which site remediation occurs. It is possible that some of these
   matters (the outcomes of which are subject to various uncertainties) may be
   resolved unfavorably against the company.
 
5. In April 1998, the Board of Directors authorized an additional share
   repurchase program of up to 5 million shares of Olin common stock, from time
   to time, as conditions warrant.
 
6. The company enters into forward sales and purchase contracts and currency
   options to manage currency risk resulting from purchase and sale commitments
   denominated in foreign currencies (principally Belgian franc, Canadian
   dollar, Irish punt and Japanese yen) and relating to particular anticipated
   but not yet committed purchases and sales expected to be denominated in those
   currencies. All of the currency derivatives expire within one year and are
   for United States dollar equivalents. The counterparties to the options and
   contracts are major financial institutions. The risk of loss to the company
   in the event of nonperformance by a counterparty is not significant. In
   accordance with Statement of Financial Accounting Standards No. 52, Foreign
   Currency Translation (SFAS 52), a transaction is classified as a hedge when
   the foreign currency transaction is designated as, and is effective as, a
   hedge of a foreign currency commitment and the foreign currency commitment is
   firm. If a transaction does not meet the criteria to qualify as a hedge, it
   is considered to be speculative. For foreign currency commitments that are
   classified as a hedge, any gain or loss on the commitment is deferred

 
   until it matures. Any unrealized gains or losses associated with foreign
   currency commitments that are classified as speculative are recognized in the
   current period. Foreign currency gains and losses realized are included in
   the income statement in Selling and Administration. If a foreign currency
   transaction previously considered as a hedge is terminated or matures before
   the transaction date of the related commitment, any deferred gain or loss
   shall continue to be deferred until the transaction date of the commitment.
 
   During 1992, the company swapped interest payments on $50 million
   principal amount of its 8% notes due 2002 to a floating rate (6.0625% at
   March 31, 1998). In June 1995, the company offset this transaction by
   swapping interest payments to a fixed rate of 6.485%. Counterparties to the
   interest rate swap contracts are major financial institutions. The risk of
   loss to the company in the event of nonperformance by a counterparty is not
   significant. The company records the net difference between the interest
   spreads as Interest Expense in the income statement.
 
   Depending on market conditions, the company may enter into futures
   contracts and put and call options in order to reduce the impact of metal
   price fluctuations, principally in copper, lead and zinc. In accordance with
   SFAS No. 80, "Accounting for Futures Contracts," futures contracts are
   classified as a hedge when the item to be hedged exposes the company to price
   risk and the futures contract reduces that risk exposure. Futures contracts
   that relate to transactions that are expected to occur are accounted for as a
   hedge when the significant characteristics and expected terms of the
   anticipated transaction are identified and it is probable that the
   anticipated transaction will occur. If a transaction does not meet the
   criteria to qualify as a hedge, it is considered to be speculative. Any gains
   or losses associated with futures contracts which are classified as
   speculative are recognized in the current period. If a futures contract that
   has been accounted for as a hedge is closed or matures before the date of the
   anticipated transaction, the accumulated change in value of the contract is
   carried forward and included in the measurement of the related transaction.
   Option contracts are accounted for in the same manner that futures contracts
   are accounted for.

7. As of January 1, 1998, the company adopted SFAS No. 130, "Reporting
   Comprehensive Income," which established standards for the reporting and
   display of comprehensive income and its components in the financial
   statements. The company does not provide for U.S. income taxes on foreign
   currency translation adjustments since it does not provide for such taxes on
   undistributed earnings on foreign subsidiaries. The components of
   comprehensive income for the three-month periods ended March 31, 1998 and
   1997 are as follows:



                                           1998    1997

THREE MONTHS ENDED MARCH 31, 1998 COMPARED TO 1997
Sales decreased 3% due primarily to a decrease in metal values.
  Selling and administration expenses as a percentage of sales were 13% in 1998
and 12% in 1997. Selling and administrative expenses increased in amount due to
higher administration expenses for information technology systems and business
planning and development activities.
  The decrease in interest income is due to the amount of income earned on the
lower average levels of cash, cash equivalents and short-term investments.
  The increase in other income is due primarily to the favorable performance of
the non-consolidated affiliates.
  The effective tax rate approximated 34.5% in 1998 and 1997.

THREE MONTHS ENDED MARCH 31, 1998 COMPARED TO 1997
Sales decreased 2% as a 3% decrease in volumes was partially offset by a 1%
increase in prices.  Operating income decreased 15%. In Chlor-Alkali sales and
operating income decreased as lower volumes (primarily caustic soda) were
partially offset by higher pricing for chlorine and caustic soda.  Sales volumes
were lower due to a variety of factors including railroad transportation
problems, reduced customer demand caused by rainy weather and reduced Asian
demand for some of our customers' products. Pool Products' operating income
decreased significantly due to lower volumes and pricing.  Exports of calcium
hypochlorite from Chinese producers have disrupted the supply/demand balance and
affected prices on a worldwide basis.  Higher manufacturing costs, including
depreciation expense, also have negatively impacted Pool Products' performance.
For the total year, estimated lower volumes and pricing in Pool Products along
with higher manufacturing costs, including depreciation expense, are expected to
decrease its operating income.  Excluding the impact of its divested businesses,
Performance Urethanes & Organics' operating performance improved due to the
restructuring of this business along with lower raw materials costs.  Despite a
slower-than-expected recovery period for the semiconductor industry, increased
volumes along with the inclusion of Aegis Inc.'s operating results contributed
to Microelectronic Materials' improved performance. Higher  

 
volumes and pricing were the primary contributors to the improved
performance in the Hydrazine and the Sulfuric Acid businesses.

THREE MONTHS ENDED MARCH 31, 1998 COMPARED TO 1997
Sales decreased 4% as a 7% decrease in metal values was partially offset by a 3%
increase in volumes.  Operating income increased 30%.  Brass' sales decreased as
lower metal values more than offset the higher volumes resulting from the strong
demand from the automotive and housing markets and improved demand from the
ammunition market.  These additional volumes along with higher earnings at A.J.
Oster resulting from higher shipments contributed to Brass' improved operating
income.  In Winchester, increased domestic commercial ammunition sales were more
than offset by lower sales in Australia.  The Australian market is suffering
from lower demand and dealer inventory build-ups as several major distributors
are liquidating stocks in response to the restrictive gun legislation.  The
profit impact from the domestic sales along with improved plant operating
performance and lower costs contributed to Winchester's improved operating
results.


ENVIRONMENTAL
In the first three months of 1998, the company spent approximately $4 million
for investigatory and remediation activities associated with former waste sites
and past operations. Spending for environmental investigatory and remedial
efforts for the full year 1998 is estimated to be $30 million. Cash outlays for
remedial and investigatory activities associated with former waste sites and
past operations were not charged to income but instead were charged to reserves
established for such costs identified and expensed to income in prior periods.
Associated costs of investigatory and remedial activities are provided for in
accordance with generally accepted accounting principles governing probability
and the ability to reasonably estimate future costs. Charges to income for
investigatory and remedial activities were $4 million for the three months ended
March 31, 1998.  Charges to income for investigatory and remedial efforts were
material to operating results in 1997 and may be material to net income in 1998
and future years.

The company's consolidated balance sheets included liabilities for future
environmental expenditures to investigate and remediate known sites amounting to
$136 million at March 31, 1998 and December 31, 1997, of which $106 million was
classified as other noncurrent liabilities. Those amounts did not take into
account any discounting of future expenditures or any consideration of insurance
recoveries or advances in technology. Those liabilities are reassessed
periodically to determine if environmental circumstances have changed and/or
remediation efforts and their costs can be better estimated. As a result of
these reassessments, future charges to income may be made for additional
liabilities.

Annual environmental-related cash outlays for site investigation and
remediation, capital projects and normal plant operations are expected to range
between $65-$90 million over the next several years. While the company does not
anticipate a material increase in the projected annual level of its
environmental-related costs, there is always the possibility that such increases
may occur in the future in view of the 

 
uncertainties associated with environmental exposures. Environmental exposures
are difficult to assess for numerous reasons, including the identification of
new sites, developments at sites resulting from investigatory studies, advances
in technology, changes in environmental laws and regulations and their
application, the scarcity of reliable data pertaining to identified sites, the
difficulty in assessing the involvement and the financial capability of other
potentially responsible parties and the company's ability to obtain
contributions from other parties and the lengthy time periods over which site
remediation occurs. It is possible that some of these matters (the outcomes of
which are subject to various uncertainties) may be resolved unfavorably against
the company.

Operating income and cash and cash equivalents on hand were used to finance the
company's seasonal working capital requirements, capital and investment
projects, dividends and the repurchase of Olin common stock.

OPERATING ACTIVITIES
Cash used for operating activities in 1998 was for an increase in working
capital and lower operating income.  Lower accounts payable and accrued
liability levels along with higher accounts receivables due to the seasonal Pool
Products business, were the main contributors to the increase in working
capital.  Cash used for operating activities in 1997 was for an increase in
working capital resulting from higher receivable levels associated with the
Niachlor acquisition, tax payments on the sale of the isocyanates business and
lower operating income.

INVESTING ACTIVITIES
Capital spending of $19.3 million in 1998 was 39% higher than 1997. Capital
spending for 1998 is estimated to increase approximately 15-30% from 1997 in
order to provide additional capacity for certain Chemicals product lines,
particularly in Microelectronic Materials and Biocides.  Microelectronic
Materials' high-purity chemical plant in Belgium was completed in April 1998.

FINANCING ACTIVITIES
At March 31, 1998, the company maintained committed credit facilities with banks
of $254 million, all of, which was available. The company believes that these
credit facilities are adequate to satisfy its liquidity needs for the near
future.

During the first quarter of 1998, the company used $39 million to repurchase
833,500 shares of its common stock, bringing the cumulative total shares
repurchased to 4,660,600 under a program approved by the board of directors in
late 1996.  It is expected that this program will be completed during the second
quarter of 1998.  In April 1998, the board of directors authorized an additional
share repurchase program of up to 5 million shares of common stock.

At March 31, 1998, the percent of total debt to total capitalization was 24.2%,
up from 24.0% at year-end 1997 and down from 30.6% at March 31, 1997. The
decrease from March 31, 1997 was due to the repayment of the 9.5% subordinated
notes ($125 million in June 1997).

 
On May 1, 1998, the company prepaid its 7.97% notes for approximately $39
million representing primarily principal and accrued interest.  The early
retirement of these notes did not have a material impact on the results of
operations.

NEW ACCOUNTING STANDARD
In June 1997, the Financial Accounting Standards Board issued SFAS No.131,
"Disclosure about Segments of an Enterprise and Related Information," which
establishes standards for the way that segment information is to be disclosed in
the financial statements along with additional information on products and
services, geographic areas and major customers.  The company is still assessing
the disclosure requirements of this standard, which is effective for the periods
beginning after December 15, 1997.

YEAR 2000 COMPUTER SYSTEMS
The company is in the process of upgrading its information technology systems
and implementing SAP.  As a result it is reviewing all internal processes and
hardware and software issues.  In addition, it is analyzing the issues relating
to the Year 2000 and is also discussing with its vendors and customers the
possibility of any interface difficulties, which may affect the company.  With
respect to the Year 2000, no significant concerns have been identified to date.
While management expects the costs associated with information technology
systems will increase over the next few years and will be higher than those in
previous years, the additional costs are not expected to be material.
