1993 DEVELOPMENTS
 
  In December 1993, Olin announced a series of strategic actions, consisting of
personnel reductions, business restructurings, including consolidations and re-
alignments within divisions, provisions for costs at sites of discontinued
businesses, future environmental liabilities and other charges. As a result of
these actions, Olin recorded a pre-tax charge to earnings of $213 million ($132
million aftertax) in the fourth quarter of 1993.
 
  On October 1, 1993, Olin sold its interest in Langenberg Kupfer und
Messingwerke GmbH & Co KG to its partner, Wieland-Werke AG, and in so doing
dissolved their four-year old German joint venture partnership. The companies
will continue joint research and development activities, and Wieland will
market certain Olin alloys in Europe.
 
  In July 1993, Olin and GenCorp Inc. announced that they are holding
discussions regarding the possible acquisition by Olin of certain assets of the
medium caliber ordnance business of GenCorp Inc. To date, the companies have
not reached a definitive agreement. Discussions are continuing and any
agreement would be subject to a number of conditions including approval by the
boards of directors of both companies.
 
INTERNATIONAL OPERATIONS 

  Olin has sales offices and subsidiaries in various countries which support the
worldwide export of products from the United States as well as overseas
production facilities. In addition, Olin has manufacturing interests, both
direct and through joint ventures, in several foreign countries.
 
  An Olin subsidiary in Ireland manufactures biocides for personal care and
industrial applications; a Brazilian subsidiary manufactures urethane systems
and Reductone(R) sodium hydrosulfite. An Olin Hunt subsidiary located in
Belgium packages toners which are marketed throughout Europe. OCG
Microelectronic Materials, a group of companies owned by Ciba-Geigy Limited and
Olin, markets photoresists, polyimides and other image forming chemicals
throughout Europe. A joint venture of OCG Microelectronic Materials, Inc. and
Fuji Photo Film Co., Ltd. manufactures photoresists in Japan and markets them
throughout the Far East.
 
  Nordesclor S.A., a joint venture with S.A. Industrias Votorantim, a Brazilian
company, manufactures calcium hypochlorite. Through a joint venture with
Sentrachem Limited, Olin has an interest in a plant in South Africa for the
production of HTH(R) pool chemicals. Olin holds a 100% interest in Hydrochim,
S.A. a French chloroisocyanurate repacking operation.
 
  Olin has interests in plants in Japan and Venezuela for the production of
urethane polyols and other specialty chemicals through joint ventures with
Asahi Glass Company Ltd. and Corimon, C.A.S.A.C.A., respectively. Olin also has
an interest in a plant recently completed in Venezuela for the production of
ethylene oxide and ethylene glycol through a joint venture with Corimon,
C.A.S.A.C.A., Petroquimica de Venezuela S.A. and the International Finance
Corporation. A joint venture of Olin and Asahi Glass Company Ltd. has an
interest in a TDI production plant in Japan with Mitsui Toatsu.

the Notes to Financial Statements on pages 28 and 29 of the 1993 Shareholders
Report and Exhibit 13 hereto are incorporated by reference in this Report.
 
CUSTOMERS AND DISTRIBUTION
 
  During 1993, no single nongovernmental customer accounted for more than 2% of
Olin's total consolidated sales and U. S. government sales accounted for 15% of
Olin's total consolidated sales. Products which Olin sells to industrial or
commercial users or distributors for use in the production of other products
constitute a major part of Olin's total sales. Some of its products, such as
pool chemicals, sporting ammunition and brass, are sold to a large number of
users or distributors, while others, such as certain industrial chemicals, are
sold in substantial quantities to a relatively small number of industrial
users.
 
  Most of Olin's products and services are marketed primarily through its sales
force and sold directly to various industrial customers, the U.S. Government
and its prime contractors to wholesalers and other distributors.
 
  Chemicals. Principal customers of Olin's chemicals products include the pulp
and paper industries, vinyl chloride manufacturers, household and industrial
cleaner suppliers, municipal and industrial wastewater treatment companies,
specialty chemical manufacturers, flexible and rigid foam suppliers, automotive
companies, packaging suppliers, the refrigeration industry, manufacturers of
adhesives, coatings, elastomers and sealants, suppliers of various consumer
products including shampoos and swimming pool sanitizers, semiconductor
manufacturers, non-impact computer printer manufacturers and defense
contractors. Principal customers of Olin's interconnect materials business are
suppliers to semiconductor manufacturers and major computer and
telecommunications manufacturers.
 
  Metals. Principal customers of Olin's copper and copper alloy strip, sheet
and rod and seamless and welded tube include producers of electrical and
electronic equipment, builders' hardware and appliances, the plumbing,
automotive and air-conditioning industries and manufacturers of a variety of
consumer goods.
 
  Olin manufactures cartridge brass for its ammunition business and for other
ammunition makers. Olin also serves numerous high-technology markets through a
thin-gauge reroll operation that produces stainless steels, high-temperature
alloys and glass sealing alloys, in addition to copper and copper alloys.
Posit-Bond(R) clad metal has made Olin a major supplier of metal to the U.S.
Mint. Olin also sells various alloys to foreign governments for coinage
purposes.
 
  The metal products business is also focused on the electronics market,
providing high performance and high quality materials needed by the electronics
industry and other advanced technology customers. These materials include Olin-
developed proprietary alloys and Copperbond(TM) treated copper foil marketed to
the printed circuit industry.
 
  Fabricated products are principally sold to ammunition manufacturers, the
U.S. Armed Forces, building product suppliers, household product manufacturers
and automotive manufacturers.
 
  Defense and Ammunition. The principal customers of the Ordnance division are
the U.S. Department of Defense and certain foreign governments. Principal
customers of the Aerospace division are the U.S. Government, major defense
contractors, aerospace companies and certain foreign governments. The principal
users of the Winchester division's products are recreational shooters, hunters,
law enforcement agencies, the power and concrete industries, the construction
industry, the U.S. Armed Forces and certain foreign governments.

GOVERNMENT SALES
 
  U.S. Government sales were approximately $354 million in 1993, $409 million
in 1992 and $453 million in 1991.
 
  Approximately 89% of such 1993 sales were to the Department of Defense or
agencies thereof. In addition, Olin operates certain Government owned plants,
including the Lake City Army Ammunition Plant in Independence, Missouri, for
which Olin receives fee income. Products and services sold to the Government,
to Government contractors or friendly foreign governments include ammunition,
propellant and specialty defense products and services. Olin also manufactures
and blends hydrazine based fuels for the Government for use as a propellant for
the Space Shuttle, satellites and expendable launch vehicles. The U.S. Mint
purchases cupronickel for nickels and Posit-Bond(R) clad metal for other U.S.
coins. Ammunition cups and strip are sold to Government contractors for
ultimate delivery to the Government.
 
  Olin's Government business is performed under both cost reimbursement and
fixed price contracts. Cost reimbursement contracts provide for the
reimbursement of allowable costs plus the payment of a fixed fee, an incentive
fee based upon actual performance as compared to contractual targets, or an
award fee based upon unilateral evaluation by the Government. Olin's fixed
price contracts are either firm fixed price contracts or incentive contracts
under which Olin shares certain savings or overruns with the Government.
 
  Government contracts generally have provisions for audit by the Government,
and cost reimbursement contracts have limitations on reimbursable costs.
Contracts may be terminated at the Government's convenience upon payment of
certain termination costs and, in some cases, profits. Olin's Government
business is subject to Government procurement regulations.
 
  Continuing reductions in the levels of defense procurement are currently
adversely affecting the Defense and Ammunition segment's performance and may
continue to do so in future years. Consequently, these reductions may also
adversely affect, to a lesser extent, Olin's financial performance in future
years, including its income, liquidity, capital resources and financial
condition. In addition, changes in the strategic direction of defense spending
and the timing of defense procurement may also adversely affect this segment
and Olin. The precise impact of defense spending cutbacks will depend on the
level of cutbacks, the extent to which these cutbacks are in the conventional
ammunition area and Olin's ability to mitigate the impact of the cutbacks with
new business or by business consolidations. Olin currently provides services to
the U.S. Government in facilities management and is pursuing other business
areas such as ordnance demilitarization. In view of continuing spending
cutbacks of the Department of Defense, the historical financial information of
the Defense and Ammunition segment and, to a lesser extent, of Olin, may not be
indicative of future performance.
 
COMPETITION
 
  Olin is in active competition with businesses producing the same or similar
products, as well as, in some instances, with businesses producing different
products designed for the same uses. With respect to certain product groups,
such as ammunition and copper alloys, and with respect to certain individual
products, such as pool chemicals, chlor-alkali and urethane products, Olin is
one of the largest manufacturers or distributors in the United States. With
respect to its many other products, Olin's share of total domestic sales varies
greatly.
 
EMPLOYEES
 
  As of December 31, 1993, Olin had approximately 12,438 employees (excluding
approximately 1,529 employees at Government owned contractor operated
facilities), approximately 11,878 of whom
 
                                       9
<PAGE>
 
were working in the United States and approximately 560 of whom were working in
foreign countries. A majority of the hourly paid employees are represented, for
purposes of collective bargaining, by various labor unions. Some labor
contracts extend for as long as four years, but during each year new agreements
must be negotiated in a number of Olin's plants. Two major labor contracts were
renewed in 1993. One major collective bargaining agreement will expire in 1994.
While relations between Olin and its employees and their various
representatives are generally considered satisfactory, there can be no
assurance that new labor contracts can be concluded without work stoppages. No
major work stoppages have occurred in the last three years.
 
RESEARCH ACTIVITIES; PATENTS
 
  Olin's research activities are conducted both on a product group and
corporate-wide basis at a number of facilities. Company sponsored research
expenditures were approximately $41 million during 1993, $39 million during
1992 and $41 million during 1991. Customer sponsored research expenditures
(primarily U.S. Government) were approximately $88 million in 1993, $84 million
in 1992 and $71 million in 1991.
 
  Olin owns, or is licensed under, a number of patents, patent applications and
trade secrets covering its products and processes. Olin believes that, in the
aggregate, the rights under such patents and licenses are important to its
operations, but does not consider any patent or license or group thereof
related to a specific process or product to be of material importance when
viewed from the standpoint of Olin's total business.
 
RAW MATERIALS AND ENERGY
 
  Olin purchases the major portion of its raw material requirements. The
principal basic raw materials required by Olin for its production of chemicals
are various hydrocarbons, salt, lime, electricity, proplylene oxide, ethylene
oxide, natural gas, toluene, sulfur, ammonia and urea. Copper, zinc and various
other nonferrous metals are required for the metals business. Lead, brass and
propellant are the principal raw materials used in the ammunition business.
Olin's principal basic raw materials are typically purchased pursuant to
multiyear contracts. In addition, Olin uses many chemicals produced in its own
operations as raw materials, intermediates or processing agents in the
production of various other chemical products. In the manufacture of
ammunition, Olin uses a substantial percentage of its own output of smokeless
powder and cartridge brass. Additional information with respect to specific raw
materials is set forth in the table above under the caption entitled "Products
and Services."
 
  Electricity is the predominant energy source for Olin's manufacturing
facilities. Olin's facilities are served by utilities which generate
electricity principally from coal and natural gas.
 
ENVIRONMENTAL AND TOXIC SUBSTANCES CONTROLS
 
  The establishment and implementation of federal, state and local standards to
regulate air, water and land quality has affected and will continue to affect
substantially all of Olin's plants. Facilities and equipment to protect the
environment do not inherently produce any significant increase in product
capacity, efficiency or revenue, and their operation generally entails
additional expense and energy consumption. Federal legislation providing for
regulation of the manufacture, transportation, use and disposal of hazardous
and toxic substances has imposed additional regulatory requirements on
industry, particularly the chemicals industry. In addition, implementation of
environmental laws, such as the Resource Conservation and Recovery Act and the
Clean Air Act, has required and will continue to require new capital
expenditures and will increase operating costs. Olin employs waste minimization
and pollution prevention programs at its manufacturing sites. In order to help
finance the cleanup of waste disposal sites, the Comprehensive Environmental
Response, Compensation and Liability Act of 1980, as amended by the Superfund
Amendments and Reauthorization Act of 1986 ("Superfund"),
 
                                       10
<PAGE>
 
imposes a tax on the sale of various chemicals, including chlorine, caustic and
certain other chemicals produced by Olin, and on the disposal of certain
hazardous wastes.
 
  Olin is party to various governmental and private environmental actions
associated with waste disposal sites and manufacturing facilities. 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. Environmental provisions charged
to income amounted to $85 million in 1993, $17 million in 1992, and $18 million
in 1991. The significant increase in 1993 resulted from expanded volumes of
contaminants uncovered while remediating a particular site, combined with the
availability of more definitive data from progressing investigatory activities
concerning both the nature and extent of contamination and remediation
alternatives at other sites. Charges to income for investigatory and remedial
efforts were material to operating results in 1993, 1992, and 1991 and may be
material to net income in future years.
 
  Cash outlays for environmental-related activities totalled $93 million in
1993 as compared with $103 million in 1992 and $90 million in 1991. During
1993, $49 million of these cash outlays were directed towards normal plant
operations for the disposal of waste and the installation, operation and
maintenance of pollution control equipment and facilities to ensure compliance
with mandated and voluntarily imposed environmental quality standards.
Comparable spending for 1992 and 1991 was $62 million and $65 million,
respectively. Included in the costs for normal plant operations were
environmental capital expenditures for pollution control equipment and
pollution abatement facilities. Spending for environmental capital expenditures
was $11 million in 1993 and $25 million in both 1991 and 1992. The 1991 and
1992 environmental capital expenditures include construction costs for a waste
water treatment facility at the company's Lake Charles plant. Historically,
Olin has funded its environmental capital expenditures through cash flow from
operations and expects to do so in the future.
 
  Cash outlays for remedial and investigatory activities associated with former
waste sites and past operations were $44 million in 1993, $41 million in 1992
and $25 million in 1991. These amounts were not charged to income but instead
were charged to reserves established for such costs identified and expensed to
income in prior years.
 
  Olin's estimated environmental liability at the end of 1993 was attributable
to 70 sites, 34 of which were on the National Priority List ("NPL"). Ten sites
accounted for approximately 75% of such liability and, of the remaining sites,
no one site accounted for more than three percent of such liability. Four of
these ten sites were in the investigatory stage of the remediation process. In
this stage, remedial investigation and feasibility studies are conducted by
either Olin, the United States Environmental Protection Agency ("EPA") or other
potentially responsible parties ("PRP's"). At another four of the ten sites, a
Record of Decision ("ROD") or its equivalent has been issued by either the EPA
or responsible state agency and Olin either alone, or as a member of a PRP
group, was engaged in performing the remedial measures required by that ROD. At
the remaining two of the ten sites, part of the site is subject to a ROD and
another part is still in the investigative stage of remediation. All ten sites
were either former manufacturing facilities or waste sites containing
contamination generated by those facilities.
 
  Total environmental-related cash outlays for 1994 are estimated to be $90
million, of which $50 million is expected to be spent on normal plant
operations, including $10 million on capital projects, and $40 million on
investigatory and remedial efforts.
 
  Annual environmental-related cash outlays for capital projects, site
investigation and remediation, and normal plant operations are expected to
range between $90-$105 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
 
                                       11
<PAGE>
 
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 financial
capability of other potentially responsible parties and the company's ability
to obtain contributions from other parties and the time periods (sometimes
lengthy) over which site remediation occurs. It is possible that some of these
matters (the outcome of which is subject to various uncertainties) may be
decided unfavorably against Olin.

Notes to Financial Statements contained in the 1993 Shareholders Report and
Exhibit 13 hereto, and "Management's Discussion and Analysis of Financial
Condition and Results of Operations" incorporated in this Report for additional
information regarding environmental matters affecting Olin.
 
ITEM 2. PROPERTIES
 
  Olin has plants at 35 separate locations in 20 states and 3 plants in 3
foreign countries. Most plants are owned; a number of small plants and portions
of one major plant are leased. Listed under Item 1 above in the table set forth
under the caption "Products and Services" are the locations at or from which
Olin's products and services are manufactured, distributed or marketed by
segment.
 
  Olin leases warehouses, terminals and distribution offices and space for
executive and branch sales offices and service departments throughout the
country and overseas.
 
ITEM 3. LEGAL PROCEEDINGS
 
  (a) In December 1979, an action was commenced in the U.S. District Court in
New York by the United States against Occidental Chemical Corporation (then
known as Hooker Chemical & Plastics Corporation) ("Oxychem"), certain related
companies, Olin and the City of Niagara Falls, New York, alleging that chemical
wastes are migrating in violation of environmental laws or regulations from a
site in Niagara Falls where Oxychem and Olin own adjacent, inactive chemical
waste landfills. The United States is seeking injunctive relief and an order
requiring Oxychem and Olin, among other things, to secure the landfill site,
install a leachate collection system and treat whatever leachate is collected,
as well as an order requiring Oxychem and Olin to place $16.5 million in trust
or provide a bond to ensure that the site will be secured. The United States is
also seeking civil penalties for each day of alleged violation of the Clean
Water Act which currently has a maximum daily penalty of $25,000.
 
  In November 1980, the State of New York filed a complaint as co-plaintiff in
the same action based upon essentially the same factual allegations as in the
suit brought by the United States. The State is seeking $100 million
compensatory damages and $100 million punitive damages. The State is also
requesting a court order to abate the alleged nuisance and penalties of $10,000
per day for alleged violations of each of four provisions of New York's
Environmental Conservation Law. In 1983, the State filed a motion to amend its
complaint to include a count under CERCLA (Comprehensive Environmental
Response, Compensation and Liability Act of 1980) alleging damage to natural
resources. In 1986, the Department of Justice filed a motion to amend its
complaint to include a CERCLA and SARA (Superfund Amendments and
Reauthorization Act of 1986) count. Oxychem and Olin have filed in opposition
to the motions and the court has deferred a ruling on both motions.
 
  The U.S. Environmental Protection Agency ("EPA") notified Olin and Oxychem of
an aggregate of $3,050,000 in agency oversight costs on the project.
 
  Under a stipulation entered into by all parties in 1984, Olin and Oxychem
undertook a site remedial investigation which was completed in October 1988.
Subsequently, the parties entered into a further
 
                                       12
<PAGE>
 
stipulation under which Oxychem and Olin conducted a feasibility study of
possible remedial measures. Olin does not expect these stipulations to have any
further effect on the outcome of this matter. The remedial investigation and
feasibility study was completed in July 1990. On September 24, 1990, EPA issued
a Proposed Remedial Action Plan and on September 29, 1990 a Record of Decision
("ROD"). The EPA selected remedy was estimated to cost $30 million. On
September 30, 1991, the EPA issued an administrative order directing Olin and
Oxychem to implement the remedy identified in the September 29, 1990 Record of
Decision. Olin and Oxychem have agreed to perform the remedy identified on such
order. The cost of any remedy is expected to be shared by Olin and Oxychem in
an agreed-upon proportion. Olin believes that any liability incurred by it in
this matter will not materially affect its financial condition.
 
  (b) In June 1987, the EPA issued a ROD recommending remedial actions and
ecological studies with respect to mercury contamination at the site of Olin's
former mercury cell chlor-alkali plant in Saltville, Virginia. In August 1987,
EPA, under Section 122 of CERCLA, asked Olin to undertake the work called for
in the ROD, and Olin agreed to do so. Olin's commitment was required to be
incorporated into a Consent Decree to be filed with a federal district court.
EPA's draft of the Consent Decree included a proposed $1.4 million Clean Water
Act penalty for past unpermitted discharges from a muck pond at the site, as
well as $570,000 in reimbursement of past EPA costs. In response to Olin's
request, EPA has agreed to reduce the costs to $456,000 and to sever the
penalty from the CERCLA action, making it the subject of separate negotiations
after execution of the Consent Decree. In 1988, the proposed $1.4 million Clean
Water Act penalty was severed from the Consent Decree entered into by Olin and
filed with the U.S. District Court for the Western District of Virginia, and
the EPA has taken no further action with respect to any proposed penalty.
 
  (c) In December 1987, a Federal Trade Commission ("FTC") administrative law
judge ruled that Olin must divest the chlorinated isocyanurates business
acquired from FMC Corporation in 1985, which includes isocyanurates
manufacturing and packaging and the Sun(R) brand trademark. The ruling stated
that the acquisition lessened competition in markets for chlorinated
isocyanurates and calcium hypochlorite dry swimming pool sanitizers. Olin
appealed this decision to the FTC. In July 1990, the FTC announced that it had
issued an order denying Olin's appeal and requiring Olin to divest itself of
such business within one year of the order becoming final following appeal.
Olin has appealed the FTC decision to the U.S. Court of Appeals. The U.S. Court
of Appeals upheld the FTC decision on February 26, 1993 and Olin's petition for
en banc review was denied. Olin petitioned for review by the U.S. Supreme Court
and such petition was denied.
 
  Olin believes that a divestment of this business would not materially affect
its financial condition or results of operations.
 
  (d) In late 1991, the EPA brought a civil action in the U.S. District Court
in Tennessee against Olin alleging violations of the Clean Air Act and
regulations thereunder with respect to mercury emissions at Olin's Charleston,
Tennessee plant. The complaint alleges, among other things, that Olin failed to
maintain a mercury cell in a manner to minimize leakage of mercury and mercury
contaminated material for a period of approximately 17 months. EPA claims civil
penalties of $25,000 per day for each alleged violation. Olin and EPA have
reached a settlement in principle in this matter pursuant to which Olin will
pay $1 million in penalties.
 
  Olin believes that any liability incurred by it in this matter will not
materially affect its financial condition.
 
  (e) As part of the continuing environmental investigation by Federal, state
and local governments of waste disposal sites, Olin has entered into a number
of settlement agreements requiring it to contribute to the cost of the
investigation and cleanup of a number of sites. This process of investigation
and cleanup is expected to continue.

  (f) On November 21, 1989, a Massachusetts state trial court ruled in Augat,
Inc. and Isotronics v. Aegis, Inc., et al. that Aegis, Inc. ("Aegis") (a
Massachusetts corporation wholly owned by Olin-Asahi Interconnect Technologies)
and a certain individual were liable to plaintiffs on matters dealing with
employee solicitation and use of certain confidential information, which the
trial court found were violations of the Massachusetts Unfair Competition
statute. On January 16, 1991, the Supreme Judicial Court of Massachusetts
upheld in part and overturned in part the lower court decision. That court held
that the defendants were liable to the plaintiffs on the narrow ground that
they had induced an employee to breach his fiduciary duty to plaintiffs in
soliciting four other Isotronics employees to join Aegis while he was still
general manager. As a result the court ruled that defendants were liable to
plaintiffs for the Isotronics losses caused by problems arising from the
departure of key managerial employees who were approached by the employee while
he and they were still employed by Isotronics, provided that the losses were
caused by events occurring before Isotronics reasonably should have replaced
the departed managerial employees with competent people. The case was remanded
to the lower court for trial on damages.
 
  After a trial on damages, the lower court entered a judgment on December 14,
1992 and subsequently modified, awarding plaintiffs $14 million in compensatory
damages, $14 million in non-compensatory damages, $10.7 million in interest,
$1.2 million in attorneys' fees, and $377,000 in costs. The judgment bears
interest at the rate of 12% per year. Defendants and plaintiffs have both
appealed. The Massachusetts Supreme Judicial Court agreed to hear the
defendants' appeal directly from the trial court and the parties are awaiting
the decision of such court.
 
  Aegis was acquired in 1987 by Olin-Asahi Interconnect Technologies, a
partnership equally owned by subsidiaries and joint ventures of Olin and Asahi
Glass Co., Ltd., of Japan.
 
  Although no allegation of wrongdoing has been made against Olin, Olin has
been named a "reach and apply" defendant under Massachusetts law in an attempt
by the plaintiffs to secure rights under a contractual obligation which may
result in a payment by Olin or one of its affiliates of a portion of whatever
the judgment is ultimately determined to be after appeal.
 
  (g) Olin and its subsidiaries are defendants in various other legal actions
arising out of their normal business activities, none of which is considered by
management to be material.

                          INDEPENDENT AUDITORS' REPORT
 
TO THE BOARD OF DIRECTORS AND SHAREHOLDERS OF OLIN CORPORATION:
 
  Under date of January 27, 1994, we reported on the consolidated balance
sheets of Olin Corporation and subsidiaries as of December 31, 1993 and 1992,
and the related consolidated statements of income, shareholders' equity and
cash flows for each of the years in the three-year period ended December 31,
1993, as contained in the 1993 Annual Report to Shareholders. Our report refers
to a change in accounting for postretirement benefits other than pensions and
income taxes in 1992. These consolidated financial statements and our report
thereon are incorporated by reference in the annual report on Form 10-K for the
year 1993. In connection with our audits of the aforementioned consolidated
financial statements, we also have audited the related financial statement
schedules as listed in Item 14(a)2 of the annual report on Form 10-K for the
year 1993. These financial statement schedules are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
financial statement schedules based on our audits.
 
  In our opinion, such financial statement schedules, when considered in
relation to the basic consolidated financial statements taken as a whole,
present fairly, in all material respects, the information set forth therein.

                           -------------------------
 
                      ARTICLE I. MEETINGS OF SHAREHOLDERS.
 
  SECTION 1. PLACE OF MEETINGS. All meetings of the shareholders of Olin
Corporation (hereinafter called the "Corporation") shall be held at such place,
either within or without the Commonwealth of Virginia, as may from time to time
be fixed by the Board of Directors of the Corporation (hereinafter called the
"Board").
 
  SECTION 2. ANNUAL MEETINGS. The annual meeting of the shareholders of the
Corporation for the election of directors and for the transaction of such other
business as may properly come before the meeting shall be held on the last
Thursday in April in each year (or, if that day shall be a legal holiday, then
on the next succeeding business day), or on such other day and/or in such other
month as may be fixed by the Board, at such hour as may be specified in the
notice thereof.
 
  SECTION 3. SPECIAL MEETINGS. A special meeting of the shareholders for any
purpose or purposes, unless otherwise provided by law or in the Articles of
Incorporation of the Corporation as from time to time amended (hereinafter
called the "Articles"), may be held at any time upon the call of the Board, the
Chairman of the Board, the President or the holders of a majority of the shares
of the issued and outstanding stock of the Corporation entitled to vote at the
meeting.
 
  SECTION 4. NOTICE OF MEETINGS. Except as otherwise provided by law or the
Articles, not less than ten nor more than sixty days notice in writing of the
place, day, hour and purpose or purposes of each meeting of the shareholders,
whether annual or special, shall be given to each shareholder of record of the
Corporation entitled to vote at such meeting, either by the delivery thereof to
such shareholder personally or by the mailing thereof to such shareholder in a
postage prepaid envelope addressed to such shareholder at his address as it
appears on the stock transfer books of the Corporation; provided, however, that
in the case of a special meeting of shareholders called by the shareholders,
such notice shall be given at least fifty days before the date of the meeting.
Notice of any meeting of shareholders shall not be required to be given to any
shareholder who shall attend the meeting in person or by proxy, unless
attendance is for the express purpose of objecting to the transaction of any
business because the meeting was not lawfully called or convened, or who shall
waive notice thereof in writing signed by the shareholder before, at or after
such meeting. Notice of any adjourned meeting need not be given, except when
expressly required by law.
 
  SECTION 5. QUORUM. Shares representing a majority of the votes entitled to be
cast on a matter by all classes or series which are entitled to vote thereon
and be counted together collectively, represented in person or by proxy at any
meeting of the shareholders, shall constitute a quorum for the transaction of
business thereat with respect to such matter, unless otherwise provided by law
or the Articles. In the absence of a quorum at any such meeting or any
adjournment or adjournments thereof, shares representing a majority of the
votes cast on the matter of adjournment, either in person or by proxy, may
adjourn such meeting from time to time until a quorum is obtained. At any such
adjourned meeting at which a quorum has been obtained, any business may be
transacted which might have been transacted at the meeting as originally
called.
 
  SECTION 6. VOTING. Unless Otherwise provided by law or the Articles, at each
meeting of the shareholders each shareholder entitled to vote at such meeting

<PAGE>
 
share of stock standing in his name on the books of the Corporation upon any
date fixed as hereinafter provided, and may vote either in person or by proxy
in writing. Unless demanded by a shareholder present in person or represented
by proxy at any meeting of the shareholders and entitled to vote thereon or so
directed by the chairman of the meeting, the vote on any matter need not be by
ballot. On a vote by ballot, each ballot shall be signed by the shareholder
voting or his proxy, and it shall show the number of shares voted.
 
  SECTION 7. JUDGES. One or more judges or inspectors of election for any
meeting of shareholders may be appointed by the chairman of such meeting, for
the purpose of receiving and taking charge of proxies and ballots and deciding
all questions as to the qualification of voters, the validity of proxies and
ballots and the number of votes properly cast.
 
  SECTION 8. CONDUCT OF MEETING. The chairman of the meeting at each meeting of
shareholders shall have all the powers and authority vested in presiding
officers by law or practice, without restriction, as well as the authority to
conduct an orderly meeting and to impose reasonable limits on the amount of
time taken up in remarks by any one shareholder.
 
                        ARTICLE II. BOARD OF DIRECTORS.
 
  SECTION 1. NUMBER. CLASSIFICATION. TERM. ELECTION. The property, business and
affairs of the Corporation shall be managed under the direction of the Board as
from time to time constituted. The Board shall consist of thirteen directors,
but the number of directors may be increased to any number, not more than
eighteen directors, or decreased to any number, not less than three directors,
by amendment of these By-laws, provided that any increase or decrease by more
than thirty percent of the number of directors last elected by the shareholders
may only be effected by the shareholders. No director need be a shareholder.
The Board shall be divided into three classes, Class I, Class II and Class III,
as nearly equal in number as possible, with the members of each class to serve
for the respective terms of office provided in the Articles, and until their
respective successors shall have been duly elected or until death or
resignation or until removal in the manner hereinafter provided. In case the
number of directors shall be increased, the additional directors to fill the
vacancies caused by such increase shall be elected in accordance with the
provisions of Section 4 of Article VI of these By-laws. Any increase or
decrease in the number of directors shall be so apportioned among the classes
by the Board as to make all classes as nearly equal in number as possible.
 
  Subject to the rights of holders of any Preferred Stock outstanding,
nominations for the election of directors may be made by the Board or a
committee appointed by the Board or by any shareholder entitled to vote in the
election of directors generally. However, any shareholder entitled to vote in
the election of directors generally may nominate one or more persons for

effect as a unanimous vote.
 
                         ARTICLE III. INDEMNIFICATION.
 
(a) Every person who is or was a director, officer or employee of the
    Corporation, or who, at the request of the Corporation, serves or has
    served in any such capacity with another corporation, partnership, joint
    venture, trust, employee benefit plan, or other enterprise shall be
    indemnified by the Corporation against any and all liability and reasonable
    expense that may be incurred by him in connection with or resulting from
    any claim, action or proceeding (whether brought in the right of the
    Corporation or any such other corporation, entity, plan or otherwise),
    civil or criminal, in which he may become involved, as a party or
    otherwise, by reason of his being or having been a director, officer or
    employee of the Corporation, or such other corporation, entity or plan
    while serving at the request of the Corporation, whether or not he
    continues to be such at the time such liability or expense shall have been
    incurred, provided that such person acted in good faith and believed that
    his conduct was in the best interests of the Corporation or such other
    corporation or entity or, in the case of an employee benefit plan, was in
    the best interests of the participants in or beneficiaries of the plan; and
    provided further that no person may be indemnified in connection with a
    proceeding charging improper personal benefit to him from the Corporation
    (or such other corporation, entity or plan) in which he was adjudged liable
    on the basis that such benefit was improperly received by him, or in
    respect of any amount recovered from him by the Corporation (or such other
    corporation) or voluntarily paid by him in respect of any claim arising
    under Section 16(b) of the Securities Exchange Act of 1934, as amended, or
    in respect of any expense incurred by him in his assertion of any claim
    against any person.
 
  As used in this Article III: (i) the terms "liability" and "expense" shall
include, but shall no be limited to, counsel fees and disbursements and amounts
of judgments, fines or penalties against, and amounts paid in settlement by, a
director, officer or employee; (ii) the terms "director", "officer" and
"employee," unless the context otherwise requires, include the estate or
personal representative of any such person; (iii) a person is considered to be
serving an employee benefit plan as a director, officer or employee of the plan
at the Corporation's request if his duties to the Corporation also impose on
duties on, or otherwise involve services by, him to the plan or, in connection
with the plan, to participants in or beneficiaries of the plan; (iv) the term
"occurrence" means any act or failure to act, actual or alleged, giving rise to
a claim, action or proceeding; and (v) service as a trustee or as a member of a
management or similar committee of a partnership or joint venture shall be
considered service as a director, officer or employee of the trust, partnership
or joint venture.
 
  The termination of any claim, action or proceeding, civil or criminal, by
judgment, settlement, conviction or upon a plea of nolo contendere, or its
equivalent, shall not create a presumption that a director, officer or employee
did not meet the standards of conduct set forth in this paragraph (a). The
 
                                     3(b)-4
<PAGE>
 
burden of proof shall be on the Corporation to establish, by a preponderance of
the evidence, that the relevant standards of conduct set forth in this
paragraph (a) have not been met.
 
(b) Any indemnification under paragraph (a) of this Article shall be made
    unless (i) the Board, acting by a majority vote of those directors who were
    directors at the time of the occurrence giving rise to the claim, action or
    proceeding involved and who are not at the time parties to such claim,
    action or proceeding (provided there are at least five such directors),
    finds that the director, officer or employee has not met the relevant
    standards of conduct set forth in such paragraph (a), or (ii) if there are
    not at least five such directors, the Corporation's principal Virginia
    legal counsel, as last designated by the Board as such prior to the time of
    the occurrence giving rise to the claim, action or proceeding involved, or
    in the event for any reason such Virginia legal counsel is unwilling to so
    serve, then Virginia legal counsel mutually acceptable to the Corporation
    and the person seeking indemnification, deliver to the Corporation their
    written advice that, in their opinion, such standards have not been met.
 
(c) Expenses incurred with respect to any claim, action or proceeding of the
    character described in paragraph (a) shall, except as otherwise set forth
    in this paragraph (c), be advanced by the Corporation prior to the final
    disposition thereof upon receipt of an undertaking by or on behalf of the
    recipient to repay such amount if it is ultimately determined that he is
    not entitled to indemnification under this Article III. No security shall
    be required for such undertaking and such undertaking shall be accepted
    without reference to the recipient's financial ability to make repayment.
    Notwithstanding the foregoing, the Corporation may refrain from, or
    suspend, payment of expenses in advance if at any time before delivery of
    the final finding described in paragraph (b), the Board or Virginia legal
    counsel, as the case may be, acting in accordance with the procedures set
    forth in paragraph (b), find by a preponderance of the evidence then
    available that the officer, director or employee has not met the relevant
    standards of conduct set forth in paragraph (a).
 
(d) No amendment or repeal of this Article III shall adversely affect or deny
    to any director, officer or employee the rights of indemnification provided
    in this Article III with respect to any liability or expense arising out of
    a claim, action or proceeding based in whole or substantial part on an
    occurrence the inception of which takes place before or while this Article
    III, as adopted by the shareholders of the Corporation at the 1986 Annual
    Meeting or the Corporation, is in effect. The provisions of this paragraph
    (d) shall apply to any such claim, action or proceeding whenever commenced,
    including any such claim, action or proceeding commenced after any
    amendment or repeal of this Article III.
 
(e) The rights of indemnification provided in this Article III shall be in
    addition to any rights to which any such director, officer or employee may
    otherwise be entitled by contract or as a matter of law.
 
(f) Notwithstanding any other provisions of this Article III, the rights of
    indemnification provided for in this Article III shall not exceed those
    permitted by Section 13.1-704 of the Virginia Stock Corporation Act.
 
                            ARTICLE IV. COMMITTEES.

  During the intervals between the meetings of the Board, the Executive and
Finance Committee shall posses and may exercise all the power and authority of
the Board (including, without limitation, all the power and authority of the
Board in 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 and Finance 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.
 
  SECTION 2. OTHER COMMITTEES. To the extent permitted by law, the Board may

by the Board to delegate such authority by written instrument to other
officers, employees or agents of the Corporation. Any such authorization by the
Board may be general or specific and shall be subject to such limitations and
restrictions as may be imposed by the Board. Any such delegation of authority
by an officer, employee or agent may be general or specific, may authorize re-

Corporation, in the name and on behalf of the Corporation, to cast the votes
which the Corporation may be entitled to cast as the holder of stock or other
securities in any other corporation, any of whose stock or other securities may
be held by the Corporation, at meetings of the holders of the stock or other
securities of such other corporation, or to consent in writing, in the name of
the Corporation as such holder, to any action by such other corporation, and

signed by the Chairman of the Board, the President or a Vice President and the
Secretary or an Assistant Secretary or the Treasurer or an Assistant Treasurer
or any other officer authorized by these By-laws or a resolution of the Board,
certifying the number of shares owned by him in the Corporation. Any such
certificate may, but need not, bear the seal of the Corporation or a facsimile
thereof. If any such certificate is countersigned by a transfer agent or
registered by a registrar other than the Corporation or an employee of the
Corporation, the signatures of any of the officers above specified upon such
certificate may be facsimiles. In case any such officer who shall have signed
or whose facsimile signature shall have been placed upon such certificate shall
have ceased to be such before such certificate is issued, it may be issued by
the Corporation with the same effect as if such officer had not ceased to be
such at the date of its issue.
 
  SECTION 2. TRANSFERS. Shares of stock of the Corporation shall be
transferable on the stock books of the Corporation by the holder in person or
by his attorney thereunto authorized by power of attorney duly executed and
filed with the Secretary or the transfer agent, but, except as hereinafter
provided in the case of loss, destruction or mutilation of certificates, no
transfer of stock shall be entered until the previous certificate, if any,
given for the same shall have been surrendered and cancelled. Except as
otherwise provided by law, no transfer of shares shall be valid as against the
Corporation, its shareholders or creditors, for any purpose, until it shall
have been entered in the stock records of the Corporation by an entry showing
from and to whom transferred. The Board may also make such additional rules and
regulations as it may deem expedient concerning the issue and transfer of
certificates representing shares of the capital stock of the Corporation.
 
  SECTION 3. RECORD DATE. For the purpose of determining shareholders entitled
to notice of or to vote at any meeting of shareholders or any adjournment
thereof, or entitled to receive payment of any dividend, or in order to make a
determination of shareholders for any other proper purpose, the Board may fix
in advance a date as the record date for any such determination of
shareholders, such date in any case to be not more than seventy days prior to
the date on which the particular action, requiring such determination of
shareholders, is to be taken. When a determination of shareholders entitled to
vote at any meeting of shareholders has been made as provided in this section,
such determination shall apply to any adjournment thereof unless the Board
fixes a new record date, which it shall do if the meeting is adjourned to a
date more than 120 days after the date fixed for the original meeting.
 
  SECTION 4. LOST. DESTROYED OR MUTILATED CERTIFICATES. In case of loss,
destruction or mutilation of any certificate of stock, another may be issued in
its place upon proof of such loss, destruction or mutilation and upon the
giving of a bond of indemnity to the Corporation in such form and in such sum
as the Board may direct; provided that a new certificate may be issued without
requiring any bond when, in the judgment of the Board, it is proper so to do.

(a) the term "period of emergency" shall mean any period during which a quorum
    of the Board cannot readily be assembled because of some catastrophic
    event.
 
                                    3(b)-10
<PAGE>
 
(b) the term "incapacitated" shall mean that the individual to whom such term
    is applied shall not have been determined to be dead but shall be missing
    or unable to discharge the responsibilities of his office; and
 
(c) the term "senior officer" shall mean the Chairman of the Board, the
    President, any corporate Vice President, the Treasurer, the Controller and
    the Secretary, and any other person who may have been so designated by the
    Board before the emergency.
 
  SECTION 2. APPLICABILITY. These Emergency By-laws, as from time to time
amended, shall be operative only during any period of emergency. To the extent
not inconsistent with these Emergency By-laws, all provisions of the regular
By-laws of the Corporation shall remain in effect during any period of
emergency.
 
  No officer, director or employee shall be liable for actions taken in good
faith in accordance with these Emergency By-laws.
 
  SECTION 3. BOARD OF DIRECTORS.
 
(a) A meeting of the Board may be called by any director or senior officer of
    the Corporation. Notice of any meeting of the Board need be given only to
    such of the directors as it may be feasible to reach at the time and by
    such means as may be feasible at the time, including publication or radio,
    and at a time less than twenty-four hours before the meeting if deemed
    necessary by the person giving notice.
 
(b) At any meeting of the Board, three directors in attendance shall constitute
    a quorum. Any act of a majority of the directors present at a meeting at
    which a quorum shall be present shall be the act of the Board. If less than
    three directors should be present at a meeting of the Board, any senior
    officer of the Corporation in attendance at such meeting shall serve as a
    director for such meeting, selected in order of rank and within the same
    rank in order of seniority.
 
(c) In addition to the Board's powers under the regular By-laws of the
    Corporation to fill vacancies on the Board, the Board may elect any
    individual as a director to replace any director who may be incapacitated
    and to serve until the latter ceases to be incapacitated or until the
    termination of the period of emergency, whichever first occurs. In
    considering officers of the Corporation for election to the Board, the rank
    and seniority of individual officers shall not be pertinent.
 
(d) The Board, during as well as before any such emergency, may change the
    principal office or designate several alternative offices or authorize the
    officers to do so.
 
  SECTION 4. APPOINTMENT OF OFFICERS. In addition to the Board's powers under
the regular By-laws of the Corporation with respect to the election of
officers, the Board may elect any individual as an officer to replace any
officer who may be incapacitated and to serve until the latter ceases to be
incapacitated.
 
  SECTION 5. AMENDMENTS. These Emergency By-laws shall be subject to repeal or
change by further action of the Board of Directors or by action of the
shareholders, except that no such repeal or change shall modify the provisions
of the second paragraph of Section 2 with regard to action or inaction prior to
the time of such repeal or change. Any such amendment of these Emergency By-
laws may make any further or different provision that may be practical and
necessary for the circumstances of the emergency.

                           OLIN DEFERRED SALARY PLAN
 
                          (Effective January 1, 1983)
 
  The Olin Deferred Salary Plan ("Plan") is adopted by Olin Corporation
("Olin") to formalize the practice of permitting management employees to defer
salary to be received from Olin.
 
PARTICIPATION AND FUNDING
 
  Participation in the Plan is limited to the select group of management and
highly compensated employees currently deferring salary and to those
participants in the Olin Corporate Incentive Compensation Plan and Performance
Compensation Programs who, after the effective date hereof, elect to defer
salary. The Plan shall be unfunded and payments to participants shall be made
from Olin's general assets.
 
CONDITIONS OF DEFERRAL
 
  Salary which Olin and the employee agree to defer shall be deferred in
accordance with the provisions of the attached form of Deferred Salary
Agreement or such other form of agreement presently in effect between Olin and
the participant.
 
MISCELLANEOUS
 
  Olin may amend, suspend or terminate the Plan at any time. Participation in
the Plan does not give any employee the right to continued employment by Olin.
<PAGE>
 
                           DEFERRED SALARY AGREEMENT
 
AGREEMENT made as of  ____________________  between OLIN CORPORATION, a Virginia
                              (Date)
corporation ("Olin"), and  ____________________________________ ("Employee"), an
                                 (Employee's Name)
employee of Olin.
 
                              W I T N E S S E T H:
 
 1. Employee's employment will continue for such period of time and at such
    rate of salary as Olin shall determine.
 
 2. Employee has elected to defer $  ___________________ per month of his or her
                                    (Amount Deferred)
   salary from Olin on the terms stated below.
 
 3. Such deferred salary shall be deferred in the form of
 
    (  ) cash
 
    (  ) Olin common stock.
 
 4. If the deferral is in the form of cash, interest on such deferred salary
    will accrue from the last calendar day of the month in which such deferred
    salary was earned to the date of payment provided for below, and subject to
    change from time to time by the Olin Board of Directors or its Compensation
    and Stock Option Committee ("Committee"), will be at a rate equal to Olin's
    after-tax cost of borrowing as determined from time to time by the
    Committee, the Chief Financial Officer, the Treasurer or the Comptroller of
    Olin. Such officers or committee shall also determine from time to time
    whether or not interest is to be compounded and the times of any
    compounding.
 
 5. If the deferral is in the form of Olin common stock, Employee's deferred
    salary account will be credited with phantom Olin common stock valued at
    the "fair market value"* of Olin common stock on a date or dates selected
    by Olin. Employee will also be credited with additional shares of phantom
    Olin common stock by treating as having been invested in such stock at its
    "fair market value"* on the relevant dividend record date the cash dividend
    which would have been paid on the shares of phantom Olin common stock
    credited to Employee's deferred salary account if those shares were then
    outstanding.
 
 6. Employee's deferred salary account established under this Agreement will be
    payable in installments on the following dates:
 
  (a)  the first installment will be on     (specify January 15 or July 15 of a
       specific year or "the next January 15 or July 15 following termination
       of employment"); and
 
  (b)  an installment will be paid on each anniversary of the first installment
       over the next _____________________________________________________ years
                                                                     (No.
                                                                     Yrs.)
       for a total of    ** installments.
 
 7. Each such installment will consist of an amount equal to   %*** of the
    following:
 
  (a)  in the case of a deferral in the form of cash, the total deferred salary
       accumulated for Employee hereunder during the period of his or her
       employment plus the interest on such installment accumulated in
       accordance with paragraph 4 to the date of payment; and
 
- -----------
*Fair market value means the average of the high and low sales prices of Olin
  common stock on the relevant date as reported on the consolidated transaction
  reporting system for New York Stock Exchange issues, or similar method of
  valuation selected by Olin.
**Maximum of 20.
***Percent multiplied by total number of installments should equal 100%.
<PAGE>
 
  (b)  in the case of a deferral in the form of Olin common stock, the total
       deferred stock account accumulated for Employee hereunder during the
       period of his or her employment, including shares credited to Employee's
       deferred salary account to reflect Olin dividends with a record date
       occurring after the date hereof and prior to the date of payment.
 
  Deferrals in the form of Olin common stock may, at the discretion of Olin,
  be paid in stock or cash, or both. Should a deferral in the form of stock
  be paid in cash, the portion of the deferred salary account to be paid will
  be valued at the "fair market value"* of Olin common stock on the fifth
  business day before payment is due. No fractional shares will be issued to
  Employee; cash based on such "'fair market value" will be paid in lieu
  thereof. Under certain circumstances, shares of Olin Common Stock delivered
  to Employee hereunder may be "restricted" and may only be sold under SEC
  Rule 144 or other exemption; if so, the stock certificate(s) will bear a
  legend to that effect.
 
 8. If Employee should die any time during the period of employment covered by
    this Agreement or prior to the time that he or she has received full
    payment of his or her deferred salary account hereunder, the remaining
    unpaid installments will be paid to the beneficiary designated in the
    Employee's will or, in the event a beneficiary has not been so designated,
    to his or her estate. At Olin's sole option, any unpaid installments of
    Employee's deferred salary account, including interest or dividend credits,
    as the case may be, may be paid to such beneficiary or estate in one lump
    sum.
 
 9. Deferral of future salary payments may be terminated in whole or in part at
    any time by either Olin or Employee by written notice to the other, and, in
    that event, such salary shall be paid currently (without interest or
    dividend credits) as earned. Termination of deferral shall be effective
    only with respect to salary not yet earned at the time such written notice
    is given.
 
10. If Employee desires to change the amount deferred, written notice of the
    change, on a form supplied by Olin, must be received by Olin's corporate
    staff department responsible for compensation matters (the "Olin
    Department") no later than the last business day of the month preceding the
    month in which the change is to be effective. Such notice will constitute
    an amendment of paragraph 2.
 
11. If Employee desires to change the distribution commencement date or the
    number of installments provided in paragraph 6, written notice of the
    change, on a form supplied by Olin, must be received by the Olin Department
    at least six months prior to the distribution commencement date. The
    distribution commencement date may only be postponed to a later date. Such
    notice will constitute an amendment of paragraphs 6 and 7.
 
12. If deferral under this Agreement of a part of Employee's salary should
    result in a reduction in the amount of pension which would otherwise be
    payable under the Olin Salaried Pension Plan, Olin will, in accordance with
    and subject to the terms and provisions of the Olin Deferral Benefit
    Pension Plan, pay a "Deferral Benefit" as provided in the latter Plan to
    Employee in the form of a supplemental pension; it being understood that
    the total pension benefit payable to Employee under the Olin Salaried
    Pension Plan and the Olin Deferral Benefit Pension Plan will not exceed

    OLIN CORPORATION AND CONSOLIDATED SUBSIDIARIES COMPUTATION OF PER SHARE
                                    EARNINGS
 
  Primary earnings per share are computed by dividing net income less the ESOP
preferred stock dividend requirement by the weighted average number of common
shares outstanding plus an equivalent number (one-for-one) of common shares
assuming the conversion of Series A stock. Fully diluted earnings per share
reflect the dilutive effect of stock options and assume the conversion of
outstanding ESOP preferred stock into an equivalent number of common shares at
the date of issuance. Net income was reduced by an additional ESOP contribution
(differential between the common and ESOP preferred dividend rates under an
assumed conversion) necessary to satisfy the debt service requirement.

Management's Discussion and Analysis of Financial Condition and Results of 
Operations

Results of Operations
1993 Compared to 1992

Although the economy has shown some recent signs of improvement, the recession
has continued to influence some of the company's major product lines. The
lingering effects of the recession, the inability to raise prices for certain
chemical products, the declining levels of defense procurement and intense price
competition in the metals industry have adversely impacted the company's
financial performance. Also in 1993, a series of strategic actions were
announced that resulted in a pretax charge to operations of $213 million ($132
million after tax) to cover costs for personnel reductions, business
restructurings involving the consolidations and re-alignments within divisions,
costs at sites of discontinued businesses, future environmental liabilities, and
other charges. As a result, the company reported a 1993 net loss of $92 million,
equal to $4.52 per share. Net income in 1992 was $9 million or 6 cents per share
and included an after-tax charge of $46 million for the adoption of two
financial accounting standards involving retiree benefits and income taxes.
Sales for 1993 were $2.4 billion, up slightly from 1992's level.

Chemicals

Chemicals 1993 sales were $1,117 million, up 12% from last year. This increase
was attributable in part to higher performance urethanes sales, particularly for
the new specialty urethanes coatings, and sales of a previously non-consolidated
affiliate in Europe. Segment net loss for 1993 was $94 million which included
$106 million of the 1993 charge, compared to 1992's net income of $21 million.
The decline in net income was due primarily to the poor performance from the
chlor-alkali and flexible urethanes businesses.

  Despite a 3% increase in the 1993 chlorine industry operating rate to 97% of
capacity, chlor-alkali financial performance was significantly behind 1992's
level. Chlorine prices increased throughout 1993 driven by strong demand from
plastic manufacturers. Conversely, demand for caustic was sluggish and adversely
affected by over-supply conditions in the marketplace. The decline in caustic
prices was greater than the increase in chlorine prices. These factors along
with higher electricity costs (caused by severe weather conditions in the
Southeast and a certain nuclear power plant shutdown) and operating problems at
the Niachlor facility were the main contributors to the 1993 decline in chlor-
alkali's financial performance.

  Sales of flexible urethanes increased over 1992's level. Higher domestic TDI
volumes and prices more than offset lower international prices and contributed
to the sales increase. Flexible polyols volumes and prices were slightly ahead
of 1992's levels. Despite the sales gains, the flexible urethanes business lost
money once again in 1993. Production problems early in the year, lower
international prices and the unfavorable performance from the company's two
Venezuelan joint ventures contributed to the additional losses.

  Sales of acids, sodium hydrosulfite and other industrial chemicals in 1993
were comparable to 1992 sales, while net profits were slightly higher due
primarily to the strong demand for sodium hydrosulfite by the textile and paper
industries.

  In the pool products business, 1993's financial performance was comparable to
1992. Improved weather conditions combined with sales of a previously non-
consolidated European affiliate accounted for the revenue increase. Higher
product exports and market share of bulk chemicals also contributed to
mitigating the profit impact of lower pricing due to on-going competitive
pressures. The additional volumes and the improved operating results from a
Brazilian joint venture offset the profit impact of lower prices, a less
favorable product mix and higher administrative expenses.

  Specialty and organic chemicals sales were equal to last year's level, while
profits increased significantly from 1992. The company expanded its biocides
products and markets in 1993, with shipments to the Far East and other
international customers more than doubling. The combination of increased
shipments and lower raw materials costs for propylene and ethylene oxide
accounted for the improvement in sales and profitability of the specialty
surfactants business.

  Sales of performance urethanes were well ahead of last year while associated
operating losses declined significantly. Higher sales volumes and a lower raw
material cost were the main contributors to the improved performance of the
polyols business. In its first full year of operations in 1993, the new
specialty urethanes coatings business built market share through competitive
pricing.

  The 1994 outlook for the Chemicals segment is positive. Chlor-alkali's results
are expected to be slightly improved in 1994. Continuing strong demand for
chlorine is anticipated while at the same time adding to the over-supply
position for caustic. The pricing outlook could become more complex as a
competitor is expected to bring on additional capacity early in the year.
Flexible urethane's financial performance is anticipated to be enhanced by
increased pricing and volume. The absence of a TDI plant maintenance turnaround
and more efficient plant operations are expected to improve flexible urethanes
manufacturing performance and product availability. Continuing strong demand
from the textile and paper industries, price stability and declining raw
material costs are anticipated to have a favorable impact on sodium
hydrosulfite's 1994 performance. In addition, the sulfuric acid business is
expected to benefit from the new acid regeneration plant. In the pool products
business higher sales volumes and reduced selling and administration expenses
are expected to improve 1994's performance. New product introductions in
biocides, surfactants, custom chemicals and an expanded hydrazine solutions
business are expected to increase sales and profits of the specialty and organic
chemicals business. In performance urethanes, differentiated products with
unique characteristics could permit the 

12
<PAGE>
 
company to maintain its market share in this business area and improve financial
performance. Sales of urethanes coatings products are estimated to double as
three new products are expected to be commercialized. In the electronic
materials business, increased demand for MQUAD, a proprietary metal package for
the semiconductor industry, is expected to be a significant contributor to a
1994 sales increase. The profit impact from the additional packaging business
along with volume and mix improvements in the company's high-purity electronic
chemicals businesses and joint venture operations are expected to contribute to
a year-to-year increase in profits.

Metals

Metals sales of $660 million declined 2% on lower metal values and reduced
levels of utility and defense-related business. The Indianapolis operations,
Mill Products and the Fabricating business, and A. J. Oster Co. (Oster) each
recorded higher volumes and improved product mix. Record commercial shipments of
brass strip were achieved in 1993. In addition, the expansion of the East Alton
mill was completed in mid-1993, contributing to improved quality and
productivity.

  Metals net income was $14 million in 1993, compared to $29 million in 1992.
The 1993 income is net of a $12 million charge for costs associated with the
1993 strategic action plan. The profit decline resulted from lower sales to the
defense and utility industries and pricing pressures as a competitor brought
additional capacity on line. In addition, losses from the Langenberg joint
venture were significantly greater than the corresponding loss in 1992. In the
1993 fourth quarter, the company sold its interest in this venture to its
partner for approximately book value, avoiding a continuation of expected losses
in 1994. Offsetting these negative income factors to some degree were the strong
profit performance from the Oster and Indianapolis operations due to higher
shipments of brass strip.

  With an expected stable-to-improving economy that will support an increased
demand for brass strip and strip-related products, the 1994 outlook for the
Metals segment is favorable. Sales are projected to increase due to higher metal
values, (primarily for copper), higher volumes and an improved product mix in
most operations. Sales of defense-related products are expected to decline due
to reduced government procurements. Excess domestic capacity may lower industry
operating rates and may create a very competitive pricing environment. Profits
from the additional volumes, cost reductions (including an early retirement
incentive program), profit improvement programs along with the absence of losses
from the German joint venture are expected to contribute to a slight increase in
segment net income.

Defense and Ammunition

Defense and Ammunition segment sales of $646 million were 8% behind 1992's level
due primarily to lower shipments of certain tank and medium caliber ammunition
and delays of awards/start-up of new Aerospace government programs. These
reduced sales volumes along with higher costs incurred on certain government
contracts in 1993 contributed to an 18% decline in segment net income, excluding
$14 million of the 1993 charge applicable to this segment.

  The Ordnance division experienced lower shipments of certain large and medium
caliber ammunition due to shrinking defense procurements. Net income was further
impacted by higher severance costs as the division continued to resize,
reflecting the declining U.S. defense budgets. In 1993, the company entered into
negotiations to purchase the medium caliber ordnance business of GenCorp Inc.
The proposed acquisition would enable the company to become a full range medium
caliber ammunition manufacturer.

  Winchester's 1993 sales decreased 2% from 1992 resulting from the completion
in 1992 of several foreign ammunition contracts and lower shipments of small
caliber military and export ammunition partially offset by higher domestic
sales. An improved product mix, higher domestic selling prices and favorable
manufacturing cost performance more than offset the reduced export profit
margins, resulting in a slight improvement in net income.

  The Aerospace division financial results were mixed for 1993; sales declined
11% while net income increased 21%. Lower sales of certain solid propellant
products and canceled/delayed Department of Defense (DoD) contract awards
contributed to the sales decline. The related profit impact from lower sales was
more than offset by the absence of cost overruns on certain fixed-price
contracts and the costs of closing the Wadsworth facility, both in 1992, along
with lower operating expenses in 1993.

  In 1994, sales for the Defense and Ammunition segment are projected to decline
as lower shipments of medium caliber and large caliber ammunition are expected
to offset higher export ammunition sales and new DoD awards in the Aerospace
division. Commercial ammunition sales are anticipated to be comparable to 1993's
level. Segment net income is projected to be slightly lower than in 1993. The
lower profit impact from the aforementioned sales and reduced revenues from
managing the Lake City Army Ammunition plant are expected to negate any profit
improvement from lower raw material costs and operating expenses.

  U.S. Government sales amounted to $354 million in 1993, $409 million in 1992
and $453 million in 1991. Approximately 89% of

                                                                              13

1993 sales were to the DoD or agencies thereof. Continuing reductions in the
levels of defense procurement are currently adversely affecting the Defense and
Ammunition segment's performance and may continue to do so in future periods.
Consequently, these reductions may also adversely affect, to a lesser extent,
the company's financial performance in future years, including its income,
liquidity, capital resources and financial condition. In addition, changes in
the strategic direction of defense spending and the timing of defense
procurement may also adversely affect this segment and the company. The precise
impact of defense spending cutbacks will depend on the level of cutbacks, the
extent to which these cutbacks are in the conventional ammunition area and the
company's ability to mitigate the impact of the cutbacks with new business or by
business consolidations. The company currently provides services to the U.S.
Government in facilities management and is pursuing other business areas such as
ordnance demilitarization. In view of continuing spending cutbacks of the DoD,
the historical financial information of the Defense and Ammunition segment, and
to a lesser extent, of the company, may not be indicative of future performance.

Other Financial Data

In December 1993, the company announced a series of strategic actions consisting
of personnel reductions, business restructurings including consolidationsand re-
alignments within divisions, provisions for costs at sites of discontinued
businesses, future environmental liabilities, and other charges. As a result of
these actions, the company recorded a pretax charge to operations of $213
million ($132 million after tax) in the fourth quarter of 1993. Major components
of this charge were the following :

   A.  Personnel Reductions: The company expects to reduce its salaried
workforce by over 10%, or 600 people, over the next two years along with minor
reductions in the hourly workforce. An early retirement incentive program has
been put in effect for the Brass and Winchester divisions, which did not
participate in a similar program offered in 1991. The pretax charge for these
actions was $42 million.

   B.  Business Restructurings: The charge provided for streamlining existing
businesses by relocating and consolidating several facilities, primarily
electronic materials businesses. Additionally, a portion of the charge related
to lower estimated proceeds from asset disposals and higher costs associated
with components of the 1991 streamlining program. The company recorded a pretax
charge of $41 million for these business restructurings.

   C.  Discontinued Businesses and Site Maintenance Costs: The pretax charge for
discontinued businesses and site maintenance was $41 million to provide for
property maintenance, security, and product liability expenses associated with
several operations which are no longer on-going businesses. Also, a previously
decommissioned plant and warehouse will be disassembled, while associated
buildings will be modified to make them suitable for future leasing.

   D.  Future Environmental Liabilities: The pretax charge of $55 million
recognized future environmental liabilities resulting from additional
investigatory activities and more extensive remediation at sites. An additional
pretax charge of $24 million related to remediation costs which the company
funded and anticipated sharing with a third party, with whom the company is now
in litigation.

   E.  Other Charges: There were various other minor charges, including assets
write-downs and long-term disability costs, which amounted to $10 million
pretax.

  The anticipated savings resulting from the workforce reductions and business
restructurings are expected to approximate $25 million in 1994 and $40 million
on an annualized basis, thereafter.

  Selling and administration expenses as a percent of sales increased to 12.4%
in 1993 from 11.7% in 1992. Increased administrative, selling and promotional
efforts for new product introductions in the Chemicals and the Defense and
Ammunition segments, higher operating expenses of the electronic materials
businesses and the European affiliate were the main contributors to the
increase. Research and development expenditures, up slightly from 1992's level,
continue to be concentrated on the company's core businesses and the exploration
of new products and technologies associated with these businesses.

  Interest expense in 1993 decreased slightly from 1992 due to lower short-term
interest rates in effect during 1993. The average borrowing rate on domestic
short-term debt decreased by 87 basis points from 1992.

  The effective tax rate was 38.7% in 1993 and 37.5% in 1992, approximating the
combined federal and state statutory rates in each year, respectively. At
December 31,1993, the company had net deferred tax assets of $63 million,
principally comprised of alternative minimum tax credits of $40 million and
temporary differences between financial statement and tax bases of assets and
liabilities. No valuation allowance has been provided because management
believes that it is more likely than not that sufficient taxable income will be
generated in the next two to four years to allow for the realization of these
tax benefits. Such future taxable income approximates $350 million.

1992 Compared to 1991

Sales in 1992 were $2.4 billion, an increase of 4% over 1991's sales. Volumes
rose 5% as most major product lines in the Metals and Chemicals segments
experienced higher shipments while overall selling prices were 1% below 1991.
Net income for 1992 was $9 million, or 6 cents per share, which included an
after-tax charge of $46 million or $2.11 per share for the adoption of the
Statements of Financial

14
<PAGE>
 
Accounting Standards (SFAS) No. 106 and No. 109, retroactive to the first
quarter of 1992. The 1991 net loss of $13 million or 92 cents per share included
an after-tax charge of $80 million for a program to streamline operations and
lower costs through the sale of certain businesses and personnel reductions. The
operating results in 1992 were impacted by the weak economy, start-up and market
entry expenses for the new aliphatic diisocyanate business, delays in the
introduction of certain new chemical products and lower profitability of the
Ordnance and Aerospace businesses.

Chemicals

The 1992 sales of $996 million increased 4% over 1991 sales while segment net
income was $21 million compared to 1991's net loss of $38 million that included
an after-tax charge of $73 million for the streamlining program. Weak economic
conditions affected many of the chemicals businesses. Lower pricing and higher
costs in flexible urethanes, lower demand for specialty and organic chemicals,
the start-up and related market penetration costs of the new aliphatics business
and unfavorable results from joint ventures contributed to the 1992 decline in
net income from 1991, after excluding the charge for the streamlining program.

  Chlor-alkali's financial performance was comparable to 1991. Chlor-alkali
sales were generally strong throughout 1992, although the impact of higher
volumes was offset by lower prices for chlorine and caustic soda. Related
profits were equivalent to 1991 as the impact of the lower selling prices was
offset by higher volumes and lower costs.

  Flexible urethanes results were lower in 1992. Sales were 3% above 1991 as
flexible polyols sales increased and worldwide TDI volumes remained at 1991
levels. Higher raw material costs for flexible polyols more than offset the
profit contribution from additional sales. TDI profitability was impacted by
lower worldwide pricing and higher raw material costs and manufacturing
expenses.

  Sales and profits of industrial chemicals were ahead of 1991 due primarily to
higher volumes. Domestic operations more than offset the unfavorable results of
the Brazilian sodium hydrosulfite facility which completed its first full year
of operations.

  Pool products sales increased 8% over 1991 while profitability increased
significantly. Price increases along with higher volumes and improved mix for
certain products were the prime contributors to the stronger financial results.
Improved raw material usage and tighter control over manufacturing costs also
led to higher gross margins.

  In the specialty and organic chemicals business, sales and profits were behind
1991 levels. Volume improvements in hydrazine solutions and specialty
surfactants were not sufficient to offset the sales decrease in biocides as
demand for traditional products declined due primarily to a customer adjusting
inventory levels, and the introduction of new products was delayed awaiting
toxicology and evaluation results. Costs of expanded manufacturing capacity and
operating activities for the new products in biocides and surfactants more than
offset the profit increases from hydrazine solutions and the propellant
business.

  Despite a 7% increase in performance urethanes sales, operating results were
significantly worse than last year. Start-up and market-entry costs for the new
aliphatics business negated increased volumes from existing products and were
the primary factors in this product line's overall negative profit performance
on a year-to-year basis. On the positive side, quality products for the new
specialty urethanes coatings business were achieved within the first month of
operations and customer response was favorable with interest in both current
products and those under development.

Metals

Segment sales were $676 million in 1992, an increase of $114 million or 20%
above 1991, due primarily to Oster, which was acquired in August 1991, and
higher shipments of brass strip, Fineweld Tube and Somers thin-strip products.

  Segment net income was $29 million, an increase of $12 million over 1991,
which included special provisions affecting a discontinued product line and
costs, primarily severance. The added profit from Oster and improved performance
from cupping, Fineweld Tube and the Indianapolis strip facility contributed to
the segment's 1992 profit increase. Segment net income was negatively impacted
by poor results from the German joint venture operations due to the depressed
European economy.

Defense and Ammunition

Defense and Ammunition sales were $704 million in 1992, down 7% from 1991 due to
contract delays/cancellations and the absence of sales from the European
sporting ammunition business which was sold in December 1991. Net income was $29
million in 1992, down 17% from 1991 due to lower profits from the Aerospace and
Ordnance divisions.

  The Aerospace division sales decreased 14% due to the absence in 1992 of
production equipment sales, delays/cancellations of DoD contracts and a weak
commercial aircraft market. Net income decreased significantly from 1991. The
recognition of losses on certain government contracts, the impact of the
contract delays and the closure of a production facility contributed to the
profitability decline.

  In Ordnance, tank ammunition sales were below 1991 levels which included
additional sales created by the Persian Gulf War. This decline more than offset
an increase in medium caliber sales in 1992, as Ordnance division's sales in
total lagged 1991's amounts. Net income for 1992 declined due to the reduced
tank ammunition vol-

                                                                              15
<PAGE>
 
umes, the recognition of losses on certain contracts and expenses incurred in
connection with the Alliant Techsystems transaction. In addition, an increase in
royalty and fee income was offset by expenses associated with the clean-up of a
medium caliber test range.

  Winchester's sales in 1992 increased $32 million over 1991 (after excluding
the European sporting ammunition sales) due to higher domestic and foreign
shipments. Domestic sporting ammunition sales increased over 1991 despite a very
competitive pricing environment. Military and commercial export volumes
increased significantly over last year due to new business, a weak U.S. dollar
in Europe and additional market share gains in South America and Australia.
Winchester's 1992 net income exceeded 1991's level. Strong domestic commercial
shipments did not totally offset lower commercial prices, but favorable
manufacturing performance, higher fees for managing the Lake City Army
Ammunition Plant and the profit contribution from the military and commercial
export sales increased the domestic operation's 1992 net income over 1991.

Other Financial Data

In the first quarter of 1991, the company announced a program to streamline
operations and lower costs and recorded a pretax charge of $129 million ($80
million after tax). Throughout 1991, efforts were undertaken to divest or
liquidate certain product lines and reduce personnel costs, accordingly.
Activities continued in 1992 including the divestment of several small product
lines.

  Selling and administration expenses increased $17 million in 1992 to 11.7% of
sales, up slightly from 11.5% in 1991. The inclusion of Oster's operating
expenses for a full year, higher pension costs and increased selling expenses
for certain chemical products were the principal reasons for the increase on a
year-to-year basis. Research and development expenditures in 1992 decreased
slightly from 1991 levels. Customer-sponsored (contract) research increased
significantly from 1991 due to increased activities relating to new government
programs.

  Interest expense in 1992 was $39 million, a decrease of $7 million or 15% from
1991, due primarily to lower average interest rates. The average interest rate
on domestic short-term debt declined to 4.2% in 1992 from 6.3% in 1991. Interest
and other income decreased by $5 million in 1992 due primarily to the
unfavorable performance of non-consolidated affiliates, particularly in South
America and Europe.

Liquidity and Investment Activity

Cash flow from operations supplemented by credit facilities and divestment
proceeds from the sale of businesses were used to finance the company's major
funding needs, namely capital projects and dividends to shareholders. Cash flow
from operating activities amounted to $137 million in 1993, $189 million in 1992
and $167 million in 1991. The decrease in 1993 was primarily attributable to
lower operating income. The effect of lower income was partially offset by
higher depreciation expense which resulted from increased capital expenditure
levels in recent years. The completion and close-out of certain government
contracts once again provided for a further liquidation of trade receivables.
Additional cash was invested in inventory in support of both realized and
anticipated expansion of the Oster business as well as introductions of new
chemical products, most notably specialty urethanes coatings. The settlement of
current liabilities other than borrowings relates to lower amounts due vendors,
increased spending for environmental remediation, and costs incurred in
executing the 1991 streamlining program. The 1992 increase in net cash generated
from operations, as compared to 1991, was attributed primarily to the collection
of receivables associated with the close-out of certain government contracts.

  Net cash used for investing activities decreased from $259 million in 1991 to
$139 million in 1992 and then to $84 million in 1993. Capital spending in 1993
decreased $41 million or 24% from 1992 due to lower environmental capital
spending and the completion in 1992 of additional brass strip capacity, the new
specialty urethanes plant and the sulfuric acid regeneration plant. Capital
spending in 1992 was comparable to 1991 which included investments in the
aliphatics diisocyanate plant, the sodium hydrosulfite plant in Brazil and the
biocides expansion in Ireland. Approximately 41% of capital expenditures in 1993
and 45% in 1992 and 1991 were dedicated to new products and expansion programs.
It is expected that 1994 capital expenditures will increase approximately 10%
from 1993 mainly to support the consolidation of some electronic materials
businesses and provide additional capacity for selected product lines.
Investment spending in 1993 and 1992 was primarily for a new ethylene oxide
joint venture in Latin America, which was completed in 1993. The company's
investment in this venture and another related Latin American venture totaled
$23 million at December 31, 1993. These ventures were unprofitable in 1993 and
experienced liquidity difficulties. The company, along with its joint venture
partners, is currently attempting to resolve these difficulties in order to
protect its recorded investment. Spending in 1991 was dedicated primarily to an
expansion of the German joint venture in metals. It is expected that 1994's
investment spending will be lower than 1993's level as the expansion programs at
the company's affiliates have been completed.

  During 1993 the company sold the facility and the assets of its contract
integrated circuit assembly operation (completing the divestiture phase of its
1991 streamlining program) and its interest in the German joint venture to its
partner. These divestments generated proceeds of $37 million. Throughout 1992,
several small product lines, such as urethane systems, Uralloy low profile
additives, sodium chlorite, the European and Singapore-based electronic
chemicals and the ethylene oxide unit were sold as part of the streamlining
program. 

16
<PAGE>
 
Proceeds from the sales amounted to $42 million including $6 million
received from a prior year sale. In 1991, the company acquired Oster, a network
of metals service centers, for $80 million and sold its European sporting
ammunition business (including its shotshell manufacturing facility in Italy) to
Browning, S.A.

  At December 31, 1993, the company maintained committed credit facilities with
banks of $367 million of which $208 million was available. The company believes
that these credit facilities are adequate to satisfy its liquidity needs for the
near future. In September 1993, the company entered into a new unsecured
revolving credit agreement with a group of banks, which replaced a prior $200
million credit agreement. The new agreement provides a maximum borrowing of $250
million and unless extended, expires on October 15, 1997. The company may select
various floating rate borrowing options.

  In 1992, the company sold 2.76 million shares of its $1 par value Series A
Conversion Preferred Stock (Series A Stock) generating net proceeds of $111
million, which were used to reduce outstanding bank loans. In addition, the
company in 1992 sold $100 million of 8% Notes due 2002 and used the proceeds to
reduce short-term debt (most of which was incurred for working capital
purposes). The company has swapped interest payments on $50 million principal
amount of these notes to a floating rate.

  In 1990, the company sold an undivided ownership interest in a designated pool
of receivables, with limited recourse, in an amount not to exceed $70 million.
An interest in new receivables is sold as collections reduce previously sold
interests. The company established certain qualifications involving the type and
term of receivables for inclusion in the pool. These qualifications had the
effect of including better-quality customer accounts in the pool, thereby
reducing the investor's risk and minimizing the likelihood of recourse. The
company's credit risk associated with the designated pool of receivables is
assessed in conjunction with the overall evaluation of trade receivables.
Reserves ascribed to these accounts are included in the "Allowance for Doubtful
Items" on the consolidated balance sheets and are not a material portion
thereof. Amounts sold were $65 million and $60 million at December 31, 1993 and
December 31, 1992, respectively.

  The establishment and implementation of federal, state and local standards to
regulate air, water and land quality has affected and will continue to affect
substantially all of the company's plants. Facilities and equipment to protect
the environment do not inherently produce any significant increase in product
capacity, efficiency or revenue, and their operation generally entails
additional expense and energy consumption. Federal legislation providing for
regulation of the manufacture, transportation, use and disposal of hazardous and
toxic substances has imposed additional regulatory requirements on industry,
particularly the chemicals industry. In addition, implementation of
environmental laws, such as the Resource Conservation and Recovery Act and the
Clean Air Act, has required and will continue to require new capital
expenditures and will increase operating costs. The company employs waste
minimization and pollution prevention programs at its manufacturing sites. In
order to help finance the cleanup of waste disposal sites, the Comprehensive
Environmental Response, Compensation and Liability Act of 1980, as amended by
the Superfund Amendments and Reauthorization Act of 1986 ("Superfund"), imposes
a tax on the sale of various chemicals, including chlorine, caustic and certain
other chemicals produced by the company, and on the disposal of certain
hazardous wastes.
  
  The company is party to various governmental and private environmental actions
associated with waste disposal sites and manufacturing facilities. 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. Environmental provisions charged to
income amounted to $85 million in 1993, $17 million in 1992, and $18 million in
1991. The significant increase in 1993 resulted from expanded volumes of
contaminants uncovered while remediating a particular site, combined with the
availability of more definitive data from progressing investigatory activities
concerning both the nature and extent of contamination and remediation
alternatives at other sites. Charges to income for investigatory and remedial
efforts were material to operating results in 1993, 1992, and 1991 and may be
material to net income in future years.

  Cash outlays for environmental-related activities totaled $93 million in 1993
as compared with $103 million in 1992 and $90 million in 1991. During 1993, $49
million of these cash outlays were directed towards normal plant operations for
the disposal of waste and the installation, operation and maintenance of
pollution control equipment and facilities to ensure compliance with mandated
and voluntarily imposed environmental quality standards. Comparable spending for
1992 and 1991 was $62 million and $65 million, respectively. Included in the
costs for normal plant operations were environmental capital expenditures for
pollution control equipment and pollution abatement facilities. Spending for
environmental capital expenditures was $11 million in 1993 and $25 million in
both 1991 and 1992. The 1991 and 1992 environmental capital expenditures include
construction costs for a waste water treatment facility at the company's Lake
Charles plant. Historically, the company has funded its environmental capital
expenditures through cash flow from operations and expects to do so in the
future.

  Cash outlays for remedial and investigatory activities associated with former
waste sites and past operations were $44 million in 1993, $41 million in 1992
and $25 million in 1991. These amounts were not charged to income but instead
were charged to reserves established for such costs identified and expensed to
income in prior years.

  The company's estimated environmental liability at the end of 1993 was
attributable to 70 sites, 34 of which were on the National Priority List (NPL).
Ten sites accounted for approximately 75% of such liability and, of the
remaining sites, no one site accounted for more than three percent of such
liability. Four of these ten sites were in the investigatory stage of the
remediation process. In this stage remedial investigation and feasibility
studies are conducted by either the company, the United States Environmental
Protection Agency (EPA) or other potentially responsible parties (PRPs). At
another four of the ten sites, a Record of Decision (ROD) or its equivalent has

                                                                              17
<PAGE>
 
been issued by either the EPA or responsible state agency and the company either
alone, or as a member of a PRP group, was engaged in performing the remedial
measures required by that ROD. At the remaining two of the ten sites, part of
the site is subject to a ROD and another part is still in the investigative
stage of remediation. All ten sites were either former manufacturing facilities
or waste sites containing contamination generated by those facilities.

  Total environmental-related cash outlays for 1994 are estimated to be $90
million, of which $50 million is expected to be spent on normal plant
operations, including $10 million on capital projects, and $40 million on
investigatory and remedial efforts.

  The company's consolidated balance sheets included reserves for future
environmental expenditures to investigate and remediate known sites amounting to
$131 million at December 31, 1993 and $66 million at December 31, 1992, of which
$91 million and $39 million were classified as other noncurrent liabilities,
respectively. Included in the reserve at December 31, 1993, were liabilities
anticipated to be shared with a third party, with whom the company is currently
in litigation. Those reserves 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 capital projects, site
investigation and remediation, and normal plant operations are expected to range
between $90-$105 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 financial capability of other potentially responsible parties
and the company's ability to obtain contributions from other parties and the
time periods (sometimes lengthy) over which site remediation occurs. It is
possible that some of these matters (the outcome of which is subject to various
uncertainties) may be decided unfavorably against the company. At December 31,
1993, the company had estimated additional contingent environmental liabilities
of $19 million which were determined in accordance with generally accepted
accounting principles.

  The percent of total debt to total capitalization (excluding the reduction in
equity for the Contributing Employee Ownership Plan (ESOP)) increased to 47.1%
at December 31, 1993, from 42.0% at year-end 1992 and was 48.5% at year-end
1991. The increase in 1993 was due to the reduction of shareholders' equity
stemming from the charge taken in 1993. The 1992 decrease was due to the
repayment of bank loans using proceeds from the Series A Stock offering and
proceeds from the sales of businesses.

  In 1989 the company established an ESOP. The ESOP trust borrowed $100 million
($40 million from the company) to purchase 1.3 million shares of the company's
convertible preferred stock. The proceeds received by the company from the
issuance of its preferred stock were used to acquire shares of its common stock.
In 1992 and 1991, the company received $15 million and $14 million, respectively
from the ESOP trust, which has repaid in full its original loan from the
company. This loan to the ESOP was financed by the company through a long-term
credit facility, which is classified on the December 31, 1993 balance sheet as
long-term debt.

  Dividends per common share were $2.20 in 1993, 1992 and 1991. Total dividends
paid on common stock amounted to $42 million in 1993 and $41 million in 1992 and
1991, while total ESOP preferred dividends, paid at an annual dividend rate of
$5.97 per share, amounted to $7 million in 1993 and $8 million in 1992 and 1991.
Dividends paid on Series A Stock were $10 million in 1993, equal to $3.64 per
share, and $9 million in 1992.

  There are a variety of legal proceedings pending or threatened against the
company. It is possible that some of these matters (the outcome of which is
subject to various uncertainties) may be decided unfavorably against the
company. Certain of these matters are discussed in Item 3, Legal Proceedings of
the Form 10-K Annual Report and in other filings of the company with the
Securities and Exchange Commission, which filings are available on request from
the company.

  The company periodically evaluates risk retention and insurance levels for
product liability, property damage and other potential areas of risk. Based on
the cost and availability of insurance and the likelihood of a loss occurring,
management decides the amount of insurance coverage to purchase from
unaffiliated companies and the appropriate amount of risk to retain. The current
levels of risk retention are believed to be appropriate and are consistent with
those of other companies in the various industries in which the company
operates.

  In late 1992, the Financial Accounting Standards Board issued SFAS No. 112,
"Employers' Accounting for Postemployment Benefits," effective commencing 1994.
This standard will not have a material impact on the company's financial
position and future operating results.

Notes to Financial Statements
($ in millions, except share data)



Accounting Policies
Basis of Presentation

The consolidated financial statements include the accounts of the company and
all majority-owned subsidiaries. Investments in 20-50% owned affiliates are
accounted for using the equity method of accounting under which investments are
recorded at cost and consist of the company's share of undistributed earnings or
losses of the affiliates.

Long-Term Contracts

Sales and cost of sales related to government contracts that extend beyond one
year are primarily recognized under the percentage-of-completion method of
accounting as costs are incurred. Profits expected to be realized on contracts
are based on the company's estimates of costs at completion compared to total
contract sales value. When the company believes the cost of completing a
contract will exceed contract-related revenues, the full amount of the
anticipated contract loss is recognized.

Inventories

Inventories are valued principally by the dollar value last-in, first-out (LIFO)
method of inventory accounting.

Property, Plant and Equipment

Property, plant and equipment are recorded at cost. Depreciation is computed on
a straight-line basis over the estimated useful lives of the related assets.
Leasehold improvements are amortized over the term of the lease or the estimated
useful life of the improvement, whichever is less. Start-up costs are expensed
as incurred.

Income Taxes

In 1992, the company adopted Statement of Financial Accounting Standards No.
109, "Accounting for Income Taxes," (SFAS No. 109) which requires recognition of
deferred tax liabilities and assets for differences between the financial
statement and tax bases of assets and liabilities using enacted tax rates in
effect for the year in which the differences are expected to reverse.

  Prior to 1992, the deferred income tax provision was based on the differences
in the timing of the recognition of transactions for financial and tax reporting
purposes.

  Deferred taxes have not been provided on the undistributed earnings of foreign
subsidiaries, since the company intends to continue to reinvest these earnings.

Foreign Currency Translation

Foreign affiliates' balance sheet amounts are translated at the exchange rates
in effect at year end, and income statement amounts are translated at the
average rates of exchange prevailing during the year. Translation adjustments
are recorded as a separate component of shareholders' equity. Foreign currency
exchange losses, net of taxes, were $4 million in 1993, $3 million in 1992 and
less than $1 million in 1991.

  The company has entered into foreign currency hedging transactions in order to
minimize exposure to fluctuations in foreign exchange rates. Realized and
unrealized gains and losses on hedging contracts designated as hedges of foreign
currency transactions are deferred and recognized in income in the same period
as the underlying transactions. All other realized and unrealized gains and
losses are recognized in income. At December 31, 1993 the company had $20
million in contracts to buy and $75 million in contracts to sell foreign
currencies during 1994.

Goodwill

Goodwill, the excess of the purchase price of acquired businesses over fair
value of the respective net assets, is amortized principally over 30 years on a
straight-line basis.

Financial Instruments

The fair value of the company's financial instruments approximates carrying
value. Fair values were estimated based on quoted market prices, where
available, or on current rates offered to the company for debt with similar
terms and maturities.

Earnings Per Share

Primary earnings per share are computed by dividing net income less the ESOP
preferred stock dividend requirement by the weighted average number of common
shares outstanding plus an equivalent number (one for one) of common shares,
assuming the conversion of Series A Stock. Fully diluted earnings per share
reflect the dilutive effect of stock options and assume the conversion of
outstanding ESOP preferred stock into an equivalent number of common shares at
the date of issuance. Net income was reduced by an additional ESOP contribution
(differential between the common and the ESOP preferred dividend rates under an
assumed conversion) necessary to satisfy the debt service requirement.

Reclassifications

Certain reclassifications have been made to prior years' financial statements to
conform to the 1993 presentation.

Trade Receivables

In December 1990, the company entered into an agreement to sell an undivided
fractional ownership interest in a designated pool of receivables, with limited
recourse, in an amount not to exceed $70 million. At December 31, 1993 and
December 31, 1992, $65 million and $60 million of accounts receivables had been
sold under this agreement. An interest in new receivables may be sold as
collections reduce previously sold interests. The company's credit risk
associated with the designated pool of receivables was assessed in conjunction
with the overall evaluation of trade receivables. Reserves ascribed to these
accounts are included in the "Allowance for Doubtful Items" on the consolidated
balance sheets and are not a material portion thereof. Operating expenses
include fees of $2 million in 1993, 1992 and 1991 related to the sale of
receivables under this agreement.

  At December 31, 1993 and December 31, 1992, trade receivables included
unbilled receivables of $73 million, related to certain government contracts
which are accounted for on the percentage-of-completion method.

Inventories

If the first-in, first-out (FIFO) method of inventory accounting had been used,
inventories would have been approximately $145 million 

24
<PAGE>
 
and $181 million higher than reported at December 31, 1993 and December 31,
1992, respectively. It is not practicable to separate the inventory into its
components because LIFO inventory values are determined principally by the use
of the dollar value LIFO method.

  Among the provisions of the note agreements are restrictions relating to
payment of dividends and acquisition of the company's capital stock. At December
31, 1993, retained earnings of approximately $96 million were not so
restricted under the provisions.

  The ESOP's purchase of preferred stock in 1989 was financed by $60 million of
notes (guaranteed by the company) and $40 million of borrowings from the
company. The loan from the company to the ESOP was financed through a long-term
credit facility. At December 31, 1993, $15 million of the Guarantee of ESOP debt
has been included in current installments of long-term debt.

  In September 1993, the company entered into a new unsecured revolving credit
agreement with a group of banks, which replaced a prior $200 million credit
agreement. The new agreement provides a maximum borrowing of $250 million and
unless extended, expires on October 15, 1997. The company may select various
floating rate borrowing options.

  In January 1992, the company issued 2.76 million shares of Series A Conversion
Preferred Stock. Proceeds of $111 million were used to repay bank loans
outstanding at December 31, 1991.

  In June 1992, the company sold $100 million of 8% notes due 2002. The proceeds
from this issue were used to reduce outstanding short-term debt. The company
then swapped interest payments on $50 million principal amount of the notes to a
floating rate.

  Annual maturities of long-term debt for the next five years are $12 million in
1994, $13 million in 1995, $53 million in 1996, $132 million in 1997 and $19
million in 1998 (excluding the expiring guarantees of ESOP debt).

Series A Preferred Stock

In January 1992, the company sold 2.76 million shares of its $1 par value Series
A Conversion Preferred Stock (Series A Stock) generating net proceeds of $111
million. Dividends on the Series A Stock are cumulative at an annual rate of
$3.64 per share. On the mandatory conversion date (March 1, 1995) each
outstanding Series A Stock will convert automatically into one share of the
company's common stock (subject to adjustment in certain events) and the right
to receive an amount of cash equal to all accrued and unpaid dividends thereon.
Automatic conversion of the outstanding Series A Stock will also occur upon
certain mergers or consolidations of the company or in connection with certain
other events. In addition, the company has the option to call the Series A
Stock, in whole or in part, for redemption prior to maturity at a predetermined
call price (payable in common stock of the company) plus an amount of cash equal
to all accrued and unpaid dividends on the Series A Stock. The predetermined
call price was $55.57 at December 31, 1993, and declines ratably to $54.18 on
January 1, 1995, and $53.95 per share thereafter.

Cost of Sales-Related Transactions

Included in cost of sales for 1993 is a pretax charge of $171 million associated
with the strategic action plan formulated during the fourth quarter. The plan
included costs of business restructurings involving the relocation and
consolidation of facilities along with lower estimated proceeds from asset
disposals and higher costs associated with components of the 1991 streamlining
program ($41 million); dismantling, product liability and on-going custodial
costs related to discontinued businesses ($41 million); future environmental
liabilities ($55 million); and other charges including asset write-downs and
long-term disability liabilities ($34 million).

                                                                              25

  In April 1991, the company announced a comprehensive program to streamline its
operations and lower costs. The program involved the planned sale of certain
businesses, the write-down of several assets to net realizable value and the
recording of anticipated operating losses of related businesses to disposal
date. In addition, the streamlining program included salaried personnel
reductions, accomplished largely through an early retirement incentive
initiative. The program resulted in a pretax charge of $129 million ($80 million
after tax) which was recorded in the first quarter of 1991.

Restructuring Charge

Included in the restructuring charge was $42 million in 1993 for workforce
reductions and $22 million in 1991 for salaried staff reductions, both of which
were accomplished largely through an early retirement incentive initiative.

Interest Expense

Interest incurred totaled $40 million in 1993, $43 million in 1992, and $48
million in 1991, of which $2 million was capitalized in 1993 and 1991 and $4
million in 1992.

Pension Plans and Retirement Benefits

Essentially all of the company's domestic pension plans are non-contributory
final-average-pay or flat-benefit plans and all domestic employees are covered.
The company's funding policy is consistent with the requirements of federal laws
and regulations. In 1993 and 1991, the company offered to certain qualified
employees an option to receive enriched pension benefits under the early
retirement incentive program in connection with the restructuring charge.

  Approximately 3% of the plan assets at December 31, 1993 and December 31, 1992
represents the company's common stock.

  The company's foreign subsidiaries maintain pension and other benefit plans
which are consistent with statutory practices and are not significant.

  The Nonbargaining Employees Pension Plan of Olin Corporation provides that if,
within three years following a change of control of the company, 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 transfer thereafter takes place, plan benefits
would automatically be increased for affected participants (and retired
participants) to absorb any plan surplus.

  The company provides certain postretirement health care and life insurance
benefits for eligible active and retired domestic employees. Effective January
1, 1992, the company adopted Statement of Financial Accounting Standards No.
106, "Employers' Accounting for Postretirement Benefits Other Than Pensions"
(SFAS 106). SFAS 106 requires the accrual method of accounting for
postretirement health care and life insurance benefits based on actuarially
determined costs to be recognized over the period from the date of hire to the
full eligibility date of employees who are expected to qualify for such
benefits. As of January 1, 1992, the company recognized the full amount of its
estimated accumulated postretirement benefit obligation, representing the
present value of the estimated future benefits payable to current retirees and
the earned portion of estimated benefits payable to active employees after
retirement. The pretax charge to 1992 earnings was $80 million with a net income
effect of $50 million or $2.30 per share. The net income and per share amounts
have been included in the statement of income as the cumulative effect of an
accounting change.

</TABLE>

  The accumulated postretirement benefit obligation was determined using the
projected unit credit method and an assumed discount rate of 71/2% in 1993 and
83/4% in 1992. The assumed health care cost trend rate used for pre-65 retirees
was 131/2% in 1993 and 14% in 1992, declining 1/2% per annum to 6%. For post-65
retirees, the company provides a fixed dollar benefit which is not subject to
escalation. In 1993 the company modified certain attributes of the
postemployment medical plan including eligibility requirements, retiree
contributions and a limit (effective year 2000) on pre-65 retiree medical
coverage.

  A one percent increase each year in the health care cost trend rate used would
have resulted in a less than $1 million increase in the aggregate service and
interest components of expense for the year 1993, and a $4 million increase in
the accumulated postretirement benefit obligation at December 31, 1993.

  In 1991 the expense associated with providing these benefits was based on life
insurance premiums and medical claims paid. Such benefit costs approximated $7
million and were expensed as incurred.

Income Taxes

As disclosed in the Summary of Significant Accounting Policies, the company
adopted SFAS 109 as of January 1, 1992. The cumulative effect on prior years of
this change in accounting principle increased 1992 net income by $4 million or
$.19 per share and is reported separately in the consolidated statement of
income.

  Included in Other Current Assets are $46 million of net current deferred
assets. Taxable income is expected to be sufficient to recover the net benefit
within the carryforward period and, therefore, no valuation allowance was
established.

  As of December 31, 1993, the company had approximately $40 million of
Alternative Minimum Tax Credits available to offset future federal income taxes
on an indefinite carryforward basis.

  The components of the 1991 net deferred tax benefit consisted primarily of
accelerated depreciation, alternative minimum tax and non-deductible reserves.

Supplemental Cash Flow Information

Cash payments during the years ended 1993, 1992 and 1991 included interest of
$39 million, $43 million and $49 million and income taxes, net of refunds, of $8
million, $15 million and $17 million, respectively.

  In 1991, A. J. Oster Co. was acquired for $80 million in cash. The fair value
of assets acquired was $90 million and liabilities assumed or created were $10
million.

Employee Stock Ownership Plan

In June 1989, an amendment to the company's Thrift Plan created an Employee
Stock Ownership Plan feature and changed the name of the Thrift Plan to the
Contributing Employee Ownership Plan. The plan is a defined contribution plan
available to essentially all domestic employees which provides a match of
employee contributions. The plan purchased from the company approximately 1.3
million shares ($100 million) of a newly authorized 1.75 million share series of
the company's ESOP preferred stock, financed by $60 million of notes guaranteed
by the company and a $40 million loan from the company. This loan has been
repaid in total to the company as of December 31, 1992. At December 31, 1993
there were 1.2 million shares of ESOP preferred stock outstanding at a value of
$80.00 per share. The annual fixed dividend rate is $5.97 per share. The ESOP
preferred stock is convertible by the holder into the company's common stock on
a one-for-one basis, subject to anti-dilutive adjustments and may be redeemed at
the option of the company after July 1, 1994, or at the option of the plan under
certain circumstances (including upon payment of withdrawing plan participant
accounts or if required to meet the plan's debt payments). The company reserves
the right to satisfy the redemption in cash, marketable obligations or common
stock. Expenses related to the plan are based on ESOP preferred and common stock
allocated to participants. These costs amounted to $10 million in 1993, 1992 and
1991. Interest incurred by the plan totaled $2 million in 1993, $3 million in
1992, and $5 million in 1991, which was funded by ESOP preferred dividends. The
ESOP preferred stock is included in shareholders' equity because the company
intends to redeem the ESOP preferred stock solely with shares of the company's
common stock, and has the ability to do so.

Stock Options

Under the stock option plans, options may be granted to purchase shares of the
company's common stock at not less than fair market value at the date of grant,
and are exercisable for a period not exceeding ten years from that date. Stock
option transactions are as follows:

  Of the outstanding options at December 31, 1993, options covering 755,449
shares are currently exercisable.

  At December 31, 1993, common shares reserved for issuance under these plans
were 1,316,794 and under additional remuneration agreements were estimated to be
50,000.

Shareholder Rights Plan

In 1986, the Board of Directors adopted a Shareholder Rights Plan expiring in
1996, which is designed to prevent an acquiror from gaining control of the
company without offering a fair price to all shareholders. Each right entitles
the shareholder to buy 1/2 share of common stock of the company at an exercise
price of $50. The rights are exercisable only if a person acquires 20% or more
of the company's common stock or commences a tender or exchange offer for 30% or
more of such stock. The company can redeem the rights at $.05 per right for a
certain time period. If any person acquires 30% or more of the common stock and
in the event of certain mergers or combinations, each right will entitle the
holder to purchase stock or other property having a value of twice the exercise
price.

Transfers between geographic areas are priced generally at prevailing market

<PAGE>
 
from the United States to unaffiliated customers were $162 million, $172 million
and $175 million in 1993, 1992 and 1991, respectively.

Acquisitions

In 1991 the company acquired A.J. Oster Co. for $80 million. This acquisition
was accounted for as a purchase and accordingly, its results of operations,
which were not material, are included in the consolidated financial statements
from the date of acquisition. The net assets acquired included working capital
of $32 million, property, plant and equipment of $14 million and other assets of
$2 million.

Dispositions

During 1993, the Company sold the facility and the assets of its contract
integrated circuit assembly operation and its interest in the German joint
venture to its partner. These transactions generated cash proceeds of $37
million.

  Throughout 1992, the company sold several small product lines such as urethane
systems, Uralloy low profile additives, sodium chlorite, the European and
Singapore-based electronic chemicals and its ethylene oxide unit. Proceeds from
these sales in 1992 amounted to $36 million.

  In December 1991, the company sold its European sporting ammunition business,
including its shotshell manufacturing facility in Italy. This transaction
generated cash proceeds of $20 million, including $6 million received in 1992.

Environmental

The company is party to various governmental and private environmental actions
associated with waste disposal sites and manufacturing facilities. 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. Environmental provisions charged to
income amounted to $85 million in 1993, $17 million in 1992, and $18 million in
1991. The significant increase in 1993 resulted from expanded volumes of
contaminants uncovered while remediating a particular site combined with the
availability of more definitive data from progressing investigatory activities
concerning both the nature and extent of contamination and remediation
alternatives at other sites. The consolidated balance sheets include reserves
for future environmental expenditures to investigate and remediate known sites
amounting to $131 million at December 31, 1993 and $66 million at December 31,
1992, of which $91 million and $39 million are classified as other noncurrent
liabilities, respectively. Included in the reserve at December 31, 1993 are
liabilities anticipated to be shared with a third party, with whom the company
is currently in litigation.

  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 time periods (sometimes lengthy)
over which site remediation occurs. It is possible that some of these matters
(the outcome of which is subject to various uncertainties) may be decided
unfavorably against the company. At December 31, 1993, the company had estimated
additional contingent environmental liabilities of $19 million which were
determined in accordance with generally accepted accounting principles.

Commitments and Contingencies

The company leases certain properties, such as manufacturing, warehousing and
office space, data processing and office equipment and railroad cars. Leases
covering these properties generally contain escalation clauses based on
increased costs of the lessor, primarily property taxes, maintenance and
insurance and have renewal or purchase options. Total rent expense charged to
operations amounted to $45 million in 1993 and $37 million in 1992 and 1991,
(sublease income is not significant). Future minimum rent payments under
operating leases having initial or remaining noncancelable lease terms in excess
of one year at December 31, 1993 are as follows (in millions): 1994-$29; 1995-
$25; 1996-$20; 1997-$17; 1998-$13; thereafter-$58.

  There are a variety of legal proceedings, contractual obligations and
environmental issues, arising out of its businesses, pending or threatened
against the company. Certain information regarding these matters can be found in
the Environmental note to the consolidated financial statements; and Item 3,
Legal Proceedings and Item 7, Management's Discussion and Analysis of Financial
Condition and Results of Operations in the 1993 Form 10-K, which is available on
request from the company.

Independent Auditors' Report
 
To the Board of Directors and Shareholders of Olin Corporation:

We have audited the accompanying consolidated balance sheets of Olin Corporation
and subsidiaries as of December 31, 1993 and 1992 and the related consolidated
statements of income, shareholders' equity and cash flows for each of the years
in the three-year period ended December 31, 1993. These consolidated financial
statements are the responsibility of the company's management. Our
responsibility is to express an opinion on these consolidated financial
statements based on our audits.

  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the consolidated financial statements are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the consolidated financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

  In our opinion, the consolidated financial statements, referred to above,
present fairly, in all material respects, the financial position of Olin
Corporation and subsidiaries as of December 31, 1993 and 1992, and the results
of their operations and their cash flows for each of the years in the three-year
period ended December 31, 1993 in conformity with generally accepted accounting
principles.

  As discussed in the notes to financial statements, the company changed its
methods of accounting for postretirement benefits other than pensions and income
taxes in 1992.

Management Report on Financial Statements

The company has prepared the accompanying consolidated financial statements and
related information for the years ended December 31, 1993, 1992, and 1991.
Management is responsible for the integrity of the financial statements, which
were prepared in conformity with generally accepted accounting principles. In
our opinion, they contain no material misstatements attributable to fraud or
error. The financial information contained elsewhere in this annual report is
consistent with the financial statements.

  The company maintains internal accounting control systems designed to provide
reliable information and reasonable assurance that assets are safeguarded from
loss or unauthorized use, that fraudulent reporting would be prevented or
detected and that all transactions are properly authorized. A well-qualified
internal audit department evaluates internal accounting control systems and
monitors compliance with the company's internal control policies and procedures.
Management believes that, as of December 31, 1993, the company's system of
internal controls is adequate to accomplish the objectives discussed herein.

  Management also recognizes its responsibility for fostering a strong ethical
climate so that the company's affairs are conducted according to the highest
standards of personal and corporate conduct. This responsibility is communicated
to all employees in the company's code of business conduct, which is publicized
throughout the company. The code of conduct addresses, among other things, the
necessity of ensuring open communication within the company; potential conflicts
of interest; compliance with all domestic and foreign laws, including those
relating to financial disclosure; and the confidentiality of proprietary
information. The company maintains a systematic program to assess compliance
with these policies.

  Our independent auditors are engaged to audit and to render an opinion on the
fairness in all material respects of our consolidated financial statements
presented in conformity with generally accepted accounting principles. In
performing their audit in accordance with generally accepted auditing standards,
they evaluate the effectiveness of our internal accounting control systems,
review selected transactions and carry out other auditing procedures to the
extent they consider necessary in expressing their opinion on our financial
statements.

  The Audit Committee of the Board of Directors, composed solely of outside
directors, meets periodically with the independent auditors, management and the
company's internal auditors to review the work of each and to evaluate matters
pertinent to internal accounting controls and financial reporting, and the
nature, extent and results of auditing activities. The Audit Committee annually
recommends to the Board of Directors the appointment of independent auditors.
The independent auditors and the company's internal audit department have access
to the Audit Committee without management's presence.
