1996 DEVELOPMENTS

On February 1, 1996, Olin and The Geon Company announced that they will
jointly construct a chlor-alkali plant at Olin's existing McIntosh, Alabama
site.

On October 10, 1996, Olin announced, among other things, Board of Directors'
approval for the sale of Olin's isocyanate businesses to ARCO Chemical Company
("ARCO"), the putting up for sale of Olin's polyol, glycol and surfactant
businesses, including production and related facilities located at its Doe Run
facility at Brandenburg, Kentucky, and the use of a portion of the proceeds
from these expected divestments to purchase up to 10% of Olin's Common Stock
in the open market from time to time as market conditions warrant. The stock
repurchase program began in January 1997.

Effective October 30, 1996, the shares of Olin Common Stock split two-for-
one for shareholders of record on October 21, 1996.

On December 4, 1996, Olin completed the sale to ARCO of Olin's isocyanate
businesses for $565 million in cash. The sale included all assets at Olin's
Lake Charles, Louisiana facility used in the manufacture of toluene
diisocyanate, aliphatic isocyanates and nitric acid.

On December 9, 1996, Olin's Board of Directors authorized the distribution
to holders of Olin Common Stock of one share of Primex Technologies, Inc.'s
common stock for every ten shares of Olin Common Stock held as of the record
date of December 19, 1996. The Securities and Exchange Commission also
declared effective the Form 10 Registration Statement in connection with this
distribution. The distribution of Primex Technologies, Inc. ("Primex") common
stock was effective December 31, 1996, with Primex stock certificates being
distributed beginning on January 6, 1997. Primex officially began business as
a separate entity on January 1, 1997.

On December 10, 1996, Olin announced that it had reached an agreement in
principle to purchase DuPont's 50% share of the companies' joint venture
Niachlor chlor-alkali plant in Niagara Falls, New York. Terms of the proposed
transaction were not disclosed. The transaction was consummated in early 1997.

On December 12, 1996, Olin redeemed its outstanding ESOP Preferred Shares,
$1.00 par value per share, by exchanging them for shares of its Common Stock.
The ESOP Preferred Shares were available only to employees through the Olin
Corporation Contributing Employee Ownership Plan ("CEOP"). The Trustee of the
CEOP received shares of Olin Common Stock equal in value to $85.75 for each
ESOP Preferred Share held, $85.75 being the appraised value of the ESOP
Preferred Shares as of December 10, 1996 as determined by the CEOP's
independent appraiser. There were approximately 878,000 shares of ESOP
Preferred Shares outstanding and approximately 1.87 million shares of Common
Stock were issued in the redemption.

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 solution sodium hydrosulfite. A microelectronic materials subsidiary
located in Belgium manufactures certain chemicals for the semiconductor
industry. Hydrochim, S.A., a French subsidiary, is an isocyanurate repacking
operation. Etoxyl, C.A., a Venezuelan subsidiary, manufactures urethane
polyols, surfactants and other specialty chemicals.


7


A group of Olin subsidiaries markets photoresists, polyimides and other
image-forming chemicals throughout Europe. A joint venture with Fuji Photo
Film Co., Ltd. manufactures photoresists, developers and flat panel display
chemicals 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

Australia. The geographic segment data contained in the Note "Segment
Information" of the Notes to Financial Statements on page 36 of the
Shareholders Report and Exhibit 13 hereto are incorporated by reference in
this Report as contained in Exhibit 13.

CUSTOMERS AND DISTRIBUTION

During 1996, no single customer accounted for more than 4% 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, urethane 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, and defense contractors. Principal customers of Olin's
interconnect materials business are suppliers to semiconductor manufacturers
and major computer and telecommunications manufacturers.

Metals and Ammunition. Principal customers of Olin's copper and copper alloy
strip, sheet, rod, wire 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.

8


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(R) 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.

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.

Because several of its businesses engage in government contracting
activities and make sales to the U.S. Government, Olin is subject to extensive
and complex U.S. Government procurement laws and regulations. These laws and
regulations provide for ongoing government audits and reviews of contract
procurement, performance and administration. Failure to comply, even
inadvertently, with these laws and regulations and with laws governing the
export of munitions and other controlled products and commodities could
subject Olin or one or more of its businesses to civil and criminal penalties,
and under certain circumstances, suspension and debarment from future
government contracts and the exporting of products for a specified period of
time.

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 and chlor-alkali, 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, 1996, Olin had approximately 9,300 employees (excluding
approximately 1,250 employees at Government-owned, contractor-operated
facilities and excluding employees of disposed businesses), approximately
8,500 of whom were working in the United States and approximately 800 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 five years, but during each year
new agreements must be negotiated in a number of Olin's plants. No major labor
contracts are scheduled to expire in 1997. 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 $39 million during 1996, $34 million during
1995 and $30 million during 1994.

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.

9


RAW MATERIALS AND ENERGY

Olin purchases the major portion of its raw material requirements. The
principal basic raw materials purchased by Olin for its production of
chemicals are various hydrocarbons, salt, lime, electricity, propylene oxide,
ethylene oxide, sulfur and ammonia. 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 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. Most of Olin's facilities are served by utilities which generate
electricity principally from coal, hydro and nuclear power.

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 manufacturing locations. 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 is enrolled in the U.S. EPA's Voluntary Industrial Toxics
Reduction Program. Olin employs waste minimization and pollution prevention
programs at its manufacturing sites.

=== === ===


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. Charges to income for
investigatory and remedial efforts were material to operating results in 1996,
1995 and 1994 and may be material to net income in future years. Such charges
to income were $70 million, $24 million and $17 million in 1996, 1995 and
1994, respectively. In connection with the sale of the isocyanates business at
Olin's Lake Charles, LA facility, a $53 million provision was recorded to
provide for contractual liabilities related to future environmental spending
at the Lake Charles site.

Cash outlays for remedial and investigatory activities associated with
former waste sites and past operations were not charged to income but instead
were charged to reserves established for such costs identified and expensed to
income in prior years. Cash outlays for normal plant operations for the
disposal of waste and the operation and maintenance of pollution control
equipment and facilities to ensure compliance with mandated and voluntarily
imposed environmental quality standards were charged to income. Historically,
Olin has funded its environmental capital expenditures through cash flow from
operations and expects to do so in the future.

10


Olin's estimated environmental liability at the end of 1996 was attributable
to 55 sites, 24 of which were on the National Priority List ("NPL"). Ten sites
accounted for approximately 80% of such liability and, of the remaining sites,
no one site accounted for more than three percent of such liability. One of
these ten sites was 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") and a Record of Decision
("ROD") or its equivalent has not been issued. At another seven of the ten
sites, a 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 1997 are estimated to be $75
million, of which $35 million is expected to be spent on investigatory and
remedial efforts, $10 million on capital projects and $30 million on normal
plant operations.

Annual environmental-related cash outlays for site investigation and
remediation, capital projects and normal plant operations are expected to
range between $75-90 million over the next several years. While Olin 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 Olin's ability to obtain contributions from other parties and the lengthy
time periods over which site remediation occurs. It is possible that some of
these matters (the outcomes of which are subject to various uncertainties) may
be resolved unfavorably against Olin.

See also Item 3, "Legal Proceedings" below, the Note "Environmental" of the
Notes to Financial Statements contained in the 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 manufacturing sites at 26 separate locations in 16 states and
Puerto Rico and six manufacturing sites in six foreign countries. Most
manufacturing sites are owned although a number of small sites 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

11


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 in
compensatory damages and $100 million in 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 $4,600,000 in agency oversight costs on the project plus
$1,900,000 for pre-judgment interest.

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 stipulation under which
Oxychem and Olin conducted a feasibility study of possible remedial measures.
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
commenced performance of the remedy identified in 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 be materially adverse to its financial condition or liquidity and,
with respect to non-environmental claims, its results of operations. See
"Environmental Matters" contained in Item 7--Management's Discussion and
Analysis and Financial Condition and Results of Operations.

(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 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.
Pursuant to the Decree, in November 1988 Olin submitted to EPA, Region III, a
work plan for remedial action, including additional stormwater run-on control
around Pond #5 and construction of a wastewater treatment plant for the
outfall from Pond #5. Olin also submitted for EPA approval a work plan for
further remedial investigation of the impact of mercury from the site on
groundwater flowing into the North Fork Holston River and its sediment from
the site to a point twenty-seven miles downstream at the Tennessee border.
During 1989 work plans

12


pursuant to the Consent Decree between EPA and Olin were approved by EPA.
Payment of past EPA costs of $228,000 plus interest was made on November 21,
1989, in accordance with the Consent Decree.

On September 5, 1991, EPA advised Olin of potential liability for
contaminated soils which were being removed in conjunction with construction
of the Rte. 634 bridge in Saltville. Olin and EPA signed a Consent Order
authorizing Olin to do the soil removal, which has been completed.

Olin completed the remedial investigation and feasibility study of the
former chlorine plant site, including Ponds # 5 and 6, in 1994. On January 18,
1995, EPA issued a Proposed Remedial Action Plan for a 30-day public comment
period. The plan called for a cap to be constructed over Pond #5, and the
excavation and retorting of soil and sediment from the former chlorine plant
site. Olin filed comments with the EPA during the public comment period in
support of alternatives to the proposed remediation plan for the site. EPA
issued a Record of Decision on September 29, 1995, recognizing in substantial
part Olin's comments. The Record of Decision calls for covering the former
waste ponds, treatment of runoff from the ponds, and additional monitoring and
investigation. Olin is presently engaged in negotiations with EPA over the
terms of a consent decree under which Olin will implement the Record of
Decision and pay approximately $455,000 for EPA's past response costs. The
Record of Decision does not address remediation of the former chlorine plant
site or the river, which are the subject of the additional investigation.

On August 29, 1994, EPA notified Olin of the company's potential liability
with respect to the "Graveyard Dump Site," located north of the former plant
site. The site is relatively small, occupying about one half acre. EPA's
investigation found about 20 capacitors and miscellaneous debris scattered
around the site as well as evidence of PCB contamination in the soils. That
work is substantially complete.

Negotiations with EPA ensued and Olin and EPA signed an Administrative Order
by Consent, effective January 5, 1995, in which Olin agreed to perform certain
response activities at the site, primarily the removal and disposal of PCB-
contaminated electrical equipment and soils.

On March 15, 1995, EPA notified Olin of liability for lead and asbestos
present at the former steam-generating plant (power plant) at the site. On
July 11, 1995, Olin and EPA entered into an Administrative Order on Consent in
which Olin agreed to remove asbestos and lead, and demolish the power plant.
The work is expected to be completed during 1997. Olin has agreed with the
site's Natural Resources Trustees to assess whether there are any natural
resource damages to the Holston River associated with releases from the site.

EPA has notified Olin of additional EPA oversight costs in the amount of
approximately $1,225,000 for the period 1990-1995.

Olin believes that any liability incurred by it in this matter will not be
materially adverse to its financial condition or liquidity. See "Environmental
Matters" contained in Item 7--Management's Discussion and Analysis of
Financial Condition and Results of Operations.

(c) 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. See "Environmental Matters" contained in
Item 7--Management's Discussion and Analysis of Financial Condition and
Results of Operations.

(d) 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.
