                                     PART I

Item I.  BUSINESS

GENERAL

         Olin Corporation is a Virginia corporation, incorporated in 1892,
having its principal executive offices in Norwalk, Connecticut. It is a
manufacturer concentrated in three business segments: Chlor Alkali Products,
Metals and Winchester(R).

         Chlor Alkali Products manufactures chlorine and caustic soda, sodium
hydrosulfite, hydrochloric acid and bleach products. Metals products include
copper and copper alloy sheet, strip and foil, welded tube, fabricated parts,
metal packages and stainless steel strip. Winchester products include sporting
ammunition, canister powder, reloading components, small caliber military
ammunition and industrial cartridges.

PRODUCTS, SERVICES  AND  STRATEGIES

                              Chlor Alkali Products

Products and Services

         We have been involved in the U.S. chlor alkali industry for more than
100 years and are a major participant in the U.S. chlor alkali market. We are
the fourth largest chlor alkali producer in the United States, with capacity of
1.15 million Electrochemical Units, or ECUs, per year, including production from
our joint venture with PolyOne Corporation, which we refer to as our Sunbelt
joint venture. We are the largest producer measured by production volume of
chlorine and caustic soda in the eastern United States, with facilities located
in Mclntosh, Alabama, Charleston, Tennessee, Augusta, Georgia, and Niagara
Falls, New York. Since transportation costs can be a significant part of the
final cost of the product to the customer, our close proximity to our customers
is a competitive advantage. Approximately two-thirds of our caustic soda
production is high purity, which normally commands a premium selling price in
the market.

         Chlorine and caustic soda are co-produced commercially primarily by the
electrolysis of salt. These co-products are produced simultaneously, and in a
fixed ratio of 1.0 ton of chlorine to 1.1 tons of caustic soda. The industry
refers to this as an ECU. Much of our chlorine and caustic produced in the U.S.
is captively consumed in the production of downstream products and vertical
integration is common. We sell chlorine and caustic not used internally to third
parties.

         Chlorine is used as a raw material in the production of thousands of
products, but a significant portion of U.S. chlorine production is consumed in
the manufacture of ethylene dichloride or EDC, a precursor for polyvinyl
chloride, or PVC. PVC is a plastic used in applications such as vinyl siding,
plumbing and automotive parts. Other U.S. end-use markets for chlorine include
chlorinated intermediates, isocyanates and water treatment. With the weakening
of the U.S. economy in 2000 and 2001, we have seen a consequent reduction in
demand for PVC, which is the largest single end-product application of chlorine.

         Caustic soda has a wide variety of end use applications, the largest of
which is in the pulp and paper industry. Caustic soda is also used in the
production of detergents and soaps, alumina and a variety of other inorganic
and organic chemicals.

         The chlor alkali industry is cyclical, both as a result of changes in
demand for each of the co-products and as a result of the large increments in
which new capacity is added. Because chlorine and caustic are produced in a
fixed ratio, the supply of one product can be constrained both by the physical
capacity of the production facilities and/or by the ability to sell the
co-product. Prices for both products respond rapidly to changes in supply and
demand. ECU prices experienced the most recent sustained peak in 1995, with the
subsequent trough coming in 1999. Prices peaked again in early 2001 and have
since retreated. In the period 1991-2001, average ECU netbacks as reported by
Chemical Market Associates, Inc. have been in excess of approximately $425 and
as low as approximately $150.

         Raw materials, including electricity, represent approximately 60% of
the total cost of producing an ECU. Electricity is the single largest variable
cost component in the production of chlor alkali products. Our electricity costs
have been stable over the last ten years because we are supplied by utilities
that primarily utilize coal, hydroelectric and nuclear power and have relatively
minor exposure to natural gas. The commodity nature of this industry places an
added emphasis on cost management and we believe that we have managed our
manufacturing costs in a manner that makes us one of the low cost producers in
the industry. In addition, as market demand grows in the future, the design of
our Sunbelt plant will enable us to expand capacity cost-effectively.

         We also manufacture a small volume of chlor alkali-related products and
we recently invested in capacity and product upgrades in these areas. These
products include chemically processed salt, hydrochloric acid, sodium
hypochlorite and hydrogen. We also sell sodium hydrosulfite into the paper,
textile and clay bleaching market.

Strategies

         Continued Role as a Preferred Supplier to Merchant Market Customers.
Based on our market research, we believe our Chlor Alkali Products business is
viewed as a preferred supplier by our merchant market customers. We will
continue to focus on providing quality customer service to our merchant market
customers. Our chlorine customers are more concentrated in the faster growing
end-markets for chlorine, such as inorganics and urethanes, and less
concentrated in the slower growing, but larger, organics and vinyls markets. We
also plan to continue developing relationships with these customers and other
customers in higher growth-end markets.

         Pursue Incremental Expansion Opportunities. Recently, we have invested
in capacity and product upgrades in our chemically processed salt, hydrochloric
acid, sodium hypochlorite and hydrogen businesses. These expansions will
increase our captive use of chlorine while increasing the sales of these
co-products. These niche markets provide opportunities to upgrade chlorine and
caustic to higher value-added applications. We also have the opportunity, when
market conditions permit, to pursue incremental expansion at our Sunbelt joint
venture.

                                     Metals

Products and Services

         We have been in the Metals business for approximately 85 years. We are
a leading manufacturer of brass and other copper alloy sheet and strip in the
United States. We also reroll and form other metals. We believe that we hold the
leading share of the U.S. copper and copper alloy sheet, strip, plate and foil
market. We refer to this market as the copper sheet and strip market. We also
believe we hold leading positions for premium priced, high performance alloys in
the United States. We participate in non-U.S. markets for high performance
alloys through exports, technology licensing, joint ventures and local
distribution. Participants in the copper sheet and strip market include
integrated brass mills, reroll mills and distributors, with many participants
engaging in multiple roles. We believe that we are the largest U.S. participant
in each of these categories. We believe that our status as the largest U.S.
participant affords us a favorable industry position as one of the lowest cost
producers. We also believe we are a quality and service leader and a specialty
product innovator.

         All of our mills are QS9000 certified and all of our plants are ISO
9000 certified. We maintain many technological advantages over our competition
through our patent-protected technologies. We believe our high performance
alloys provide superior strength, conductivity and formability to customers in
the automotive, electrical, electronic and telecommunications industries. We
currently hold 29 U.S. patents associated with high performance alloys and 64
other U.S. patents related to various proprietary processing and technical
capabilities, many of which are also registered in foreign jurisdictions. To
further our global presence, we have established relationships with Yamaha
Corporation in Japan (joint venture) and Wieland-Werke A.G of Germany (technical
alliance) that provide

                                       3

<PAGE>

us with greater global reach and enable us to participate in the Asian and
European high performance alloys markets. In June 2001, we acquired the stock of
Monarch Brass & Copper Corp., which we refer to as Monarch, for approximately
$49 million. Monarch was a privately held, specialty brass manufacturer
headquartered in Waterbury, CT, with annual revenues of approximately $95
million in 2000. Monarch enhances our high performance copper alloy production
capabilities and expands our portfolio of products.

         In addition, through sales of our clad metal, produced by a proprietary
cladding process, we believe we are a major supplier of coinage metal to the
U.S. Mint. We also supply coinage metal to foreign governments. We produce
ammunition cartridge cups for use captively in the manufacture of our Winchester
sporting ammunition, which constitutes a small portion of our total Metals
segment output. We also sell cartridge brass to other ammunition makers. This
relationship, along with our growing fabrication business for select customers,
provides us with a significant "captive" customer base.

         Brass and other copper alloys are manufactured by melting copper
together with various combinations of zinc, lead or other metals. The resulting
product goes through a series of processes, including casting, hot rolling,
milling, cold rolling, annealing, cleaning and slitting. The principal end-use
markets for metal products include: automotive for connectors and radiators;
electronics for lead frames, connectors, wiring and telecommunications
applications; ammunition; coinage; and other applications such as builder's
hardware, plumbing supplies and welding tube for utility condensers and
industrial heat exchangers.

         Historically, the copper sheet and strip market has exhibited GDP-type
growth. In the late 1990's and in 2000, this market expanded at a rapid pace
principally due to the strength of the U.S. economy. From 1997 to 2000, the
market grew at an annualized growth rate of approximately 8%. In 2001 and into
2002, the copper sheet and strip market has been facing lower volume demands
because of the economic downturn.

Strategies

         Continue Profitable Growth Globally. Our strategy is to be a leading
worldwide supplier of specialty copper-based products and related engineered
materials. We intend to achieve this goal by building our high performance
alloys business on a global basis. In 2001, we took a number of actions to
further develop our global presence, including expanding our high quality
integrated mill at East Alton, Illinois, acquiring Monarch and entering into a
technical alliance with Wieland-Werke.

         Maintain Premier Specialty Product Innovator Position. We believe that
we manufacture more high performance alloys than any other competitor, and we
are investing to expand our product line. Our specialty products include
proprietary high performance alloys and materials that meet strength, gauge,
formability and conductivity requirements for applications in our customers'
industries.

         Increase Cost Efficiencies. We will continue to focus on achieving
economies of scale, improved manufacturing processes and innovation in pursuit
of cost reductions. We strive for profit improvements primarily through yield
improvements, increased equipment utilization and capacity enhancements.

         Continue Our Quality Leadership. Our plants all maintain ISO 9000
certification and our integrated mills are QS9000 certified. We continue to
conduct detailed customer surveys, which indicate that our products satisfy or
exceed customer expectations. We have received many "supplier of the year"
awards from our customers, some of whom are among the largest or most respected
companies in their respective industries. For example, Square D and Universal
Fasteners each awarded us "supplier of the year" for 2000.

         Leverage Our Service and Distribution Leadership for Growth. We believe
that we are one of the service and distribution leaders in the copper-based
metals industry. Our A.J. Oster distribution system extends throughout the
United States and also includes facilities in Puerto Rico and Mexico. We sell
directly from the mill to large volume customers, and to small and medium size
customers through A.J. Oster and other licensed distributors. We intend to
leverage our service leadership and our distribution network to improve our
just-in-time delivery services and our customized order capabilities.

                                   Winchester

Products and Services

         Winchester is in its 135/th/ year of operation. Winchester is a premier
developer and manufacturer of small caliber ammunition for sale to domestic and
international retailers, law enforcement agencies and domestic and international
militaries. We believe we are a leading U.S. producer of ammunition for
recreational shooters, hunters, law enforcement agencies and the U.S. Armed
Forces. Our legendary Winchester product line includes all major gauges and
calibers of shotgun shells, rimfire and centerfire ammunition for pistols and
rifles, canister powder, reloading components and industrial cartridges. We
believe we are the market leader in both shotshell and centerfire pistol
ammunitions. We expect the sporting ammunition industry to show a relatively
flat growth profile for 2002 to 2004.

         Winchester has strong relationships throughout the sales and
distribution chain and strong ties to traditional dealers and distributors.
Winchester has built its business with key high volume mass merchants and
specialty sporting goods retailers. We have consistently developed
industry-leading ammunition, and in seven of the last ten years, including each
of the past four years, Winchester was recognized with the "Ammunition of the
Year" award from the Shooting Industry Academy of Excellence for its
technological and design leadership. In 2000, we received Wal-Mart's "Supplier
of the Year" award in the hunting and fishing category.

         The following table lists products and services of our Winchester

Strategies

         Leverage Existing Strengths. Winchester will focus on seeking new
opportunities to leverage the legendary Winchester brand name and will continue
to offer a full line of ammunition products to the markets we serve, with
specific focus on investments that lower our costs and that make Winchester
ammunition the retail brand of choice.

         Focus on Product Line Growth. With a long record of pioneering new
product offerings, Winchester has built a strong reputation as an industry
innovator. This includes the introduction of reduced-lead and non-lead products,
which are growing in popularity for use in indoor shooting ranges and for
outdoor hunting.

INTERNATIONAL OPERATIONS

         We have 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, we manufacture and distribute
sodium hydrosulfite in Brazil.

         Yamaha-Olin Metal Corporation manufactures high-performance copper
alloys in Japan for sale to the electronics industry throughout the Far East.
One of our subsidiaries loads and packs sporting and industrial ammunition in
Australia. See the Note "Segment Information" of the Notes to Consolidated
Financial Statements in Item 8, for geographic segment data. We are
incorporating our segment information from that Note into this section of our
Form 10-K.

CUSTOMERS AND DISTRIBUTION

         During 2001, no single customer accounted for more than 5% of
consolidated sales. Products we sell to industrial or commercial users or
distributors for use in the production of other products constitute a major part
of our total sales. We sell some of our products, such as sporting ammunition
and brass, to a large number of users or distributors, while we sell others,
such as chlorine and caustic soda, in substantial quantities to a relatively
small number of industrial users. We discuss the customers for each of our three
businesses in more detail above under "Products and Services."

         We market most of our products and services primarily through our sales
force and sell directly to various industrial customers, the U.S. Government and
its prime contractors, to wholesalers and other distributors.

         Because we engage in some government contracting activities and make
sales to the U.S. Government, we are 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 us or one or more of our 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

         We are 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 chlor
alkali products, we are among the largest manufacturers or distributors in the
United States. We encounter competition in price, delivery, service,
performance, product innovation and product recognition and quality, depending
on the product involved.

EMPLOYEES

         As of December 31, 2001, we had approximately 5,900 employees
(excluding approximately 100 employees at Government-owned, contractor-operated
facilities), with approximately 5,800 working in the United States and
approximately 100 working in foreign countries. Various labor unions represent a
majority of our hourly-paid employees for collective bargaining purposes.
Although some labor contracts extend for as long as five years, others are for
shorter periods, and we must re-negotiate those more frequently. A labor
contract for approximately forty employees at the Brass Division's Bryan, Ohio
facility expires in September 2002 and a labor

                                        6

<PAGE>

contract for approximately 210 employees at the Chlor Alkali Products Division's
McIntosh, Alabama facility expires in April 2003. While we believe our relations
with our employees and their various representatives are generally satisfactory,
we cannot assure you that we can conclude these labor contracts or any other
labor agreements without work stoppages.

RESEARCH ACTIVITIES; PATENTS

         Our research activities are conducted on a product-group basis at a
number of facilities. Company-sponsored research expenditures were approximately
$5 million during each of 2001 and 2000 and $7 million during 1999.

         We own or license a number of patents, patent applications and trade
secrets covering our products and processes, particularly for use in our Metals
segment. We believe that, in the aggregate, the rights under our patents and
licenses are important to our operations, but we do not consider any individual
patent or license or group of patents and licenses related to a specific process
or product to be of material importance to our total business.

RAW MATERIALS AND ENERGY

         We purchase the major portion of our raw material requirements. The
principal basic raw materials we purchase for our production of Chlor Alkali
Products are salt, electricity, sulfur dioxide, chlorine and hydrogen. 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
Winchester business. We typically purchase our principal basic raw materials
pursuant to multiyear contracts. In the manufacture of ammunition, we use a
substantial percentage of our own output of cartridge brass. We provide
additional information with respect to specific raw materials in the tables
above under "Products and Services."

         Electricity is the predominant energy source for our manufacturing
facilities. Most of our facilities are served by utilities which generate
electricity principally from coal, hydro and nuclear power.

</TABLE>

         The establishment and implementation of federal, state and local
standards to regulate air, water and land quality have affected and will
continue to affect substantially all of our 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. We employ waste
minimization and pollution prevention programs at our manufacturing sites.

         We are a party to various governmental and private environmental
actions associated with waste disposal sites and manufacturing facilities. We
provide for associated costs of investigatory and remedial activities 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 the
past three years and may be material to net income in future years. Such charges
to income were $14 million, $15 million and $17 million in 2001, 2000 and 1999,
respectively.

         Cash outlays for remedial and investigatory activities associated with
former waste sites and past operations were not charged to income but instead to
reserves established for such costs that we 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, we funded our environmental
capital expenditures through cash flow from operations and we expect to do so in
the future.

                                        7

<PAGE>

         Our estimated environmental liability is attributable to approximately
60 sites, 18 of which were on the United States Environmental Protection
Agency's ("USEPA") National Priority List ("NPL"). Ten sites accounted for
approximately 73% of the reserve taken for such liabilities and, of the
remaining sites, no one site accounted for more than 2% of such liability. Two
of these ten sites are in the investigatory stage of the remediation process. In
this stage, remedial investigation and feasibility studies are conducted by
either us or other potentially responsible parties and a Record of Decision,
which we also refer to as a ROD, or its equivalent has not yet been issued. At
four of the ten sites, a ROD or its equivalent has been issued by either the
USEPA or responsible state agency and we, either alone or as a member of a group
of potentially responsible parties, were engaged in performing the remedial
measures required by that ROD. At the remaining four 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.

         Our consolidated balance sheets included liabilities for future
environmental expenditures to investigate and remediate known sites amounting to
$100 million at December 31, 2001, and $110 million at December 31, 2000, of
which $73 million and $85 million were classified as other noncurrent
liabilities, respectively. Those amounts did not take into account any
discounting of future expenditures or any consideration of insurance recoveries
or advances in technology. We reassess those liabilities periodically to
determine if environmental circumstances and/or remediation efforts and our
estimate of related costs have changed. As a result of these reassessments,
future charges to income may be made for additional liabilities.

         Total environmental-related cash outlays for 2002 are estimated to be
$50 million, of which $27 million is expected to be spent on remedial and
investigatory efforts, $5 million on capital projects and $18 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 approximately $40-$50 million over the next several years, $25 million
to $30 million of which is expected to be charged against reserves recorded on
our balance sheet. While we do not anticipate a material increase in the
projected annual level of our 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 our 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 us. At December 31,
2001, we estimate we may have additional contingent environmental liabilities of
$40 million in addition to the amounts for which we have already taken a
reserve.

         See our discussion of our environmental matters in Item 3, "Legal
Proceedings" below, the Note "Environmental" of the Notes to Consolidated
Financial Statements contained in Item 8, and Item 7, "Management's Discussion
and Analysis of Financial Condition and Results of Operations."

ADDITIONAL FACTORS THAT MAY AFFECT FUTURE RESULTS


         In addition to the other information in this Form 10-K, the following
factors should be considered in evaluating Olin and our business. All of our
forward-looking statements should be considered in light of these factors.
Additional risks and uncertainties that we are unaware of or that we currently
deem immaterial also may become important factors that affect us.

         Sensitivity to Global Economic Conditions and Cyclicality -- Our
operating results could be negatively affected during economic downturns.

         The business of most of our customers, particularly our automotive,
coinage, electrical connectors, telecommunications and distributor customers,
are, to varying degrees, cyclical and have historically experienced periodic
downturns. These economic and industry downturns have been characterized by
diminished product demand, excess manufacturing capacity and, in some cases,
lower average selling prices. Therefore, any significant downturn in our
customers' markets or in global economic conditions could result in a reduction
in demand for our products and could adversely affect our results of operations
or financial condition. As a result of the depressed economic conditions
beginning in the fourth quarter of 2000 and continuing throughout 2001, our
vinyls, urethanes and pulp and paper customers have had lower demand for our
Chlor Alkali Products, our automotive, coinage, electrical connectors,
telecommunications and housing customers have had lower demand for our Metals
products and our ammunition customers have had lower demand for our Winchester
products. Lower demand in all three of our business segments has adversely
affected our business and results of operations. Specifically, cutbacks in
production of automobiles and the further slowdown in the coinage and
telecommunications markets have adversely affected our results of operations in
our Metals segment.

                                        8

<PAGE>

         Although we don't generally sell a large percentage of our products
directly to customers abroad, a large part of our financial performance is
dependent upon a healthy economy beyond the United States. Our customers sell
their products abroad. As a result, our business is affected by general economic
conditions and other factors in Western Europe and most of East Asia,
particularly China and Japan, including fluctuations in interest rates, market
demand, labor costs and other factors beyond our control. The demand for our
customers' products, and therefore, our products, is directly affected by such
fluctuations. Our joint venture, Yamaha-Olin Metal Corporation, located in
Japan, is particularly susceptible to these fluctuations. We cannot assure you
that events having an adverse effect on the industries in which we operate will
not occur or continue, such as a further downturn in the Western European, Asian
or world economies, increases in interest rates, unfavorable currency
fluctuations or a prolonged slowdown in the automotive, coinage, electrical
connectors or telecommunications industries.

         Cyclical Pricing Pressure -- Our profitability could be reduced by
declines in average selling prices in the industries in which we operate,
particularly declines in the ECU netback price.

         Our historical operating results reflect the cyclical and sometimes
volatile nature of the chemical, metals and ammunition industries. We experience
cycles of fluctuating supply and demand in each of our business segments,
particularly in the Chlor Alkali Products division, which results in changes in
selling prices. Periods of high demand, tight supply and increasing operating
margins tend to result in increased capacity and production until supply exceeds
demand, generally followed by periods of oversupply and declining prices. The
industry build cycle, and its impact on industry pricing, has been most
pronounced in our Chlor Alkali Products segment. For example, in 1995 and 1996,
the chlor alkali industry was very profitable due to a tight supply/demand
balance, which resulted in both higher operating rates and higher ECU prices.
Higher profits led to reinvestment to expand capacity. This new capacity became
operational in 1998 and 1999, resulting in industry over-capacity. This
imbalance was exacerbated by falling demand as a result of the Asian financial
crisis. The supply/demand imbalance resulted in both lower operating rates and
lower ECU prices, and in 1999, many chlor alkali producers had operating losses.
The supply/demand balance improved due to improved economic conditions in 2000
compared to 1999, and ECU prices increased in 2000 compared to 1999. As the U.S.
and world economies have deteriorated in 2001, the chlor alkali industry again
is experiencing a period of oversupply because of lower industry demand for both
chlorine and caustic.

         Price in the chlor alkali industry is a major supplier selection
criterion. We have little or no ability to raise prices in this large commodity
market. Decreases in the average selling prices of our products could have a
material adverse effect on our profitability. For example, assuming all other
costs remain constant, a $10 change in our ECU netback causes a corresponding
$11 million increase or decrease in our annual revenues and pre-tax profits,
when we are operating at full capacity. While we strive to maintain or increase
our profitability by reducing costs through improving production efficiency,
emphasizing higher margin products, and by controlling selling and
administration expenses, we cannot assure you that these efforts will be
sufficient to offset fully the effect of changes in pricing on operating
results.

         Because of the cyclical nature of our businesses, we cannot assure you
that pricing or profitability in the future will be comparable to any particular
historical period, including the most recent period shown in our operating
results. We cannot assure you that the chlor alkali industry will not experience
adverse trends in the future, or that our operating results and/or financial
condition will not be adversely affected by them.

         Our Metals and Winchester segments are also subject to changes in
operating results as a result of cyclical pricing pressures, but to a lesser
extent than the Chlor Alkali Products segment. We generally pass changes in
prices for copper and other metals along to our customers as part of the
negotiated price of the finished product in most of our Metals segment product
lines. However, our Metals segment experiences manufacturing or pricing pressure
with respect to its tolling charges, and we cannot assure you that adverse
trends in pricing and margins will not affect operating results in the future.
Similarly, selling prices of ammunition are affected by changes in raw material
costs and market demand, and declines in average selling prices of our
Winchester segment could adversely affect our profitability.

         Indebtedness -- Our indebtedness could adversely affect our financial
condition, limit our ability to grow and compete and prevent us from fulfilling
our obligation under our indebtedness.

         As of December 31, 2001, we had approximately $431 million of
indebtedness outstanding, excluding our guarantee of $97.5 million of
indebtedness of our Sunbelt joint venture. This does not include the $190
million of available lines of credit on which we had nothing outstanding on that
date. As of December 31, 2001, our indebtedness represented 61.4% of our total
capitalization. On January 3, 2002, we entered into a new $140 million
three-year revolving senior credit facility, which we refer to as our senior
credit facility. Our senior credit facility replaced the $190 million credit
facilities available on December 31, 2001. As of March 1, 2002, we had $140
million of availability under our senior credit facility.

         Our indebtedness could adversely affect our financial condition, limit
our ability to grow and compete and prevent us from fulfilling our obligations
under our indebtedness. Despite our level of indebtedness, our senior credit
facility and the indenture governing our 9.125% Senior Notes permit us to borrow
additional money. If we borrow more money, as we intend to do in order to grow
our business, the risks related to our indebtedness could be increased
significantly.

         Debt Service -- We may not be able to generate sufficient cash to
service our debt, which may require us to refinance our indebtedness or default
on our scheduled debt payments. Our ability to generate cash depends on many
factors beyond our control.

         Our ability to generate sufficient cash flow from operations to make
scheduled payments on our debt depends on a range of economic, competitive and
business factors, many of which are outside our control. We cannot assure you
that our business will generate sufficient cash flow from operations. If we are
unable to meet our expenses and debt obligations, we may need to refinance all
or a portion of our indebtedness on or before maturity, sell assets or raise
equity. We cannot assure you that we would be able to refinance any of our
indebtedness, sell assets or raise equity on commercially reasonable terms or at
all, which could cause us to default on our obligations and impair our
liquidity. Our inability to generate sufficient cash flow to satisfy our debt
obligations, or to refinance our obligations on commercially reasonable terms,
would have an adverse effect on our business, financial condition and results of
operations, as well as on our ability to satisfy our debt obligations. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations."


         Imbalance in Demand for Our Chlor Alkali Products - A loss of customers
for our chlorine or caustic soda could cause an imbalance in demand for these
products, which could have an adverse effect on our results of operations.

         Chlorine and caustic soda are produced simultaneously, and in a fixed
ratio of 1.0 ton of chlorine to 1.1 tons of caustic soda. The loss of a chlorine
or caustic soda customer could cause an imbalance in demand for our chlorine and
caustic soda products. An imbalance in demand may require us to reduce
production of both chlorine and caustic soda or take other steps to correct the
imbalance. Since we cannot store chlorine we may not be able to respond to an
imbalance in demand for these products as quickly or efficiently as some of our
competitors. If a substantial imbalance occurred, we would need to reduce prices
or take other actions that could have a negative impact on our results of
operations and financial condition.


         Competition - We face competition from other chemical, brass and
ammunition companies, which could adversely affect our revenues and financial
condition.

         We are in active competition with companies producing the same or
similar products, as well as, in some instances, with companies 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 chlor
alkali products, we are among the largest manufacturers or distributors in the
United States. We encounter competition in price, delivery, service,
performance, product innovation, and product recognition and quality, depending
on the product involved. With respect to certain products, some of our
competitors are larger, have greater financial resources and have less debt than
we do. As a result, these competitors may be better able to withstand a change
in conditions within the industries in which we operate and throughout the
economy as a whole. If we do not compete successfully, our business, financial
condition and results of operations could be adversely affected.


         Environmental Costs - We have ongoing environmental costs, which could
also have a material adverse effect on our financial condition.

         The nature of our operations and products, including the raw materials
we handle, exposes us to the risk of liabilities or claims with respect to
environmental matters. We have incurred, and will continue to incur, significant
costs and capital expenditures in complying with these environmental laws and
regulations. We discussed these costs in more detail above under "Environmental
and Toxic Substance Controls."

         The ultimate costs and timing of environmental liabilities are
difficult to predict. Liability under environmental laws relating to
contaminated sites can be imposed retroactively and on a joint and several
basis. One liable party could be held responsible for all costs at a site,
regardless of fault, percentage of contribution to the site or the legality of
the original disposal. We could incur significant costs, including cleanup
costs, natural resources damages, civil or criminal fines and sanctions and
third-party claims, as a result of past or future violations of, or liabilities
under, environmental laws. In addition, future events, such as changes to or
more rigorous enforcement of environmental laws, could require us to make
additional expenditures, modify or curtail our operations and/or install
pollution control equipment. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations -Environmental Matters."


         Production Hazards - Our facilities are subject to operating hazards,
which may disrupt our business.

         We are dependent upon the continued safe operation of our production
facilities. Our production facilities are subject to hazards associated with the
manufacture, handling, storage and transportation of chemical materials and
products and ammunition, including leaks and ruptures, explosions, fires,
inclement weather and natural disasters, unscheduled downtime and environmental
hazards. From time to time in the past, we have had incidents that have
temporarily shut down or otherwise disrupted our

                                       10

<PAGE>

manufacturing, causing production delays and resulting in liability for
workplace injuries and fatalities. Some of our products involve the manufacture
and/or handling of a variety of explosive and flammable materials. Use of these
products by our customers could also result in liability if an explosion, fire,
spill or other accident were to occur. We cannot assure you that we will not
experience these types of incidents in the future or that these incidents will
not result in production delays or otherwise have a material adverse effect on
our business, financial condition or results of operations.


         Tax Audits - We are currently subject to ongoing tax audits, which may
result in additional tax payments.

         We are currently subject to ongoing audits by the Internal Revenue
Service in connection with our Federal tax returns for the years from 1992 to
1998; however, we have closed all tax years through 1991. Depending on the
outcome of these audits, we may be required to pay additional taxes, and any
additional taxes and related interest could be substantial. We have reserved
amounts which we believe will be sufficient for any adverse outcome, but the
actual amount of any such additional taxes and the timing of any such payments
is uncertain.

Item 2.  PROPERTIES

         We have manufacturing sites at 22 separate locations in 13 states and
Puerto Rico and two manufacturing sites and a distribution facility in three
foreign countries. Most manufacturing sites are owned although a number of small
sites are leased. We listed the locations at or from which our products and
services are manufactured, distributed or marketed in the tables set forth under
the caption "Products and Services."

         We lease 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) We continue to work with the USEPA with respect to remediation of
mercury contamination at the site of our former mercury cell Chlor Alkali
Products plant in Saltville, Virginia.

         Additional work is required including the covering of certain former
waste ponds and additional investigation and monitoring. We began work to cover
the ponds in 2001 and expect the work to be completed in 2003.

         We have met several times with the site's Natural Resources Trustees at
the Trustees' request regarding past releases from the Saltville site and the
nearby Holston River. We do not know whether the Trustees will claim any natural
resource damages associated with releases from the site. We believe that any
liability incurred in this matter will not be materially adverse to our
financial condition or liquidity. See "Environmental Matters" contained in Item
7--"Management's Discussion and Analysis of Financial Condition and Results of
Operations."

         (b) As part of the continuing environmental investigation by federal,
state and local governments of waste disposal sites, we have entered into a
number of settlement agreements requiring us to contribute to the cost of the
investigation and cleanup of a number of sites. We expect this process of
investigation and cleanup to continue. See "Environmental Matters" contained in
Item 7 --"Management's Discussion and Analysis of Financial Condition and
Results of Operations."

         (c) As a result of a recent internal audit of our East Alton, Illinois
facility, we determined that recent upgrades to certain operations may not have
been completed in full compliance with all USEPA regulations. Although our
facility received a modification to its air emissions permit from the Illinois
Environmental Protection Agency ("IEPA") for the upgrade, the permit
modification may not have addressed or completely addressed all applicable
regulations. On February 15, 2002, we disclosed to USEPA and IEPA that the
upgrade may not have been in compliance with all aspects of USEPA regulations.
We have offered to work with USEPA and IEPA to determine the nature and extent
of the issues and to correct them, if necessary. As part of the resolution of
this issue, we may need to enhance pollution control equipment at our East Alton
facility and pay some penalty. While we do not expect that the ultimate
resolution of this matter will have a material impact on our financial position,
we cannot, at this time, determine the financial impact, if any, on our results
of operations in a particular year.

                                       11

         (d) We and our subsidiaries are defendants in various other legal
actions arising out of our normal business activities, none of which management
believes to be material.

Item 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

         We did not submit any matter to a vote of security holders during the

Item 7.  Management's Discussion and Analysis of Financial Condition
and Results of Operations

Business Background

     Our operations are concentrated in three businesses: Chlor Alkali Products,
Metals and Winchester. All three are capital intensive manufacturing businesses
with growth rates closely tied to the general economy. While each segment has a
commodity element to it, our ability to influence pricing is quite limited and
the portion of the business that is strictly commodity varies by division. Our
Chlor Alkali Products business is a commodity business where all supplier
products are identical and price is the major supplier selection criterion. We
have little or no ability to influence prices in this large, global commodity
market. Cyclical price swings, driven by changes in supply/demand, can be abrupt
and significant and, given capacity in our Chlor Alkali Products business, can
lead to very significant changes in our overall profitability. While a majority
of Metals sales are of a commodity nature, this business has a significant
volume of specialty engineered products targeted for specific end-use markets.
In these applications, technical capability and performance differentiate the
product and play a significant role in product selection and thus price is not
the only selection criterion. Winchester also has a commodity element to its
business but a majority of Winchester ammunition is sold as consumer branded
product where there is the opportunity to differentiate certain offerings
through innovative new product development and enhanced product performance.
While competitive pricing versus other branded ammunition products is important,
it is again not the only factor in product selection.

______________

     For the full year 2001, we recorded restructuring charges totaling $39
million pretax and unusual items of $3 million pretax for a total of $42 million
pretax or $0.67 diluted EPS.


                                       14

<PAGE>

     In the third quarter, we recorded a pretax charge for restructuring and
unusual items of $29 million (or $0.40 diluted EPS) primarily for costs
associated with a salaried workforce reduction through an early retirement
incentive program. Cost of Goods Sold and Other Income included $2 million and
$1 million respectively, of unusual items. Cost of Goods Sold included the
write-off of inventory associated with cancelled customer orders. Other Income
included the write-off of an investment in an E-commerce company. The
third-quarter restructuring charge of $26 million related to the 190 employees
retiring in connection with the retirement program and represented primarily
pension and postretirement benefit curtailment losses and severance. As of
December 31, 2001, 150 employees had retired and the remainder will retire in
the first quarter of 2002. The severance of $4 million recorded in Accrued
Liabilities will be paid out of our operating cash flows over time.

     In the fourth quarter we recorded a restructuring charge of $13 million
pretax, or $.27 diluted EPS, primarily for costs associated with idling our
Indianapolis brass mill, consolidating distribution operations of the recently
acquired Monarch Brass & Copper Corp. ("Monarch") with the A.J. Oster metals
service center business, and reducing staffing levels in Chlor Alkali Products.
A significant portion of the charge relating to the idling of the Indianapolis
facility represented pension and postretirement curtailment losses and severance
for 200 employees. Another portion of the charge related to 38 Chlor Alkali
employees who accepted our offer of a voluntary special separation program
whereby employees accept a voluntary lay off and receive full separation
benefits and also receive their accrued pension benefits at the same time. The
balance of the restructuring charge relates to costs associated with the
consolidation of certain Monarch facilities in order to optimize distribution
operations. The severance and fringe benefits of $8 million recorded in Accrued
Liabilities will be paid out of our operating cash flows over time.

     In 2001, we were notified that we would receive shares of Prudential
Insurance Company as a result of its decision to demutualize from a mutual
company to a stock company. We recorded a gain of $11 million in other income in
2001. We received the shares and immediately sold them in January 2002.

     At midnight on December 3, 2000, a work stoppage began at the Metals and
Winchester manufacturing facilities at East Alton, IL, after the union and we
were unable to agree on a new labor contract. After several weeks of
negotiations, the parties entered into a new labor contract and the union
workers returned to work on January 23, 2001. The work stoppage had an adverse
impact in 2000 and 2001 on the profitability of the Metals and Winchester
operations, including product fulfillment issues, additional expenses and
contract settlement costs.

     In June 2000, we signed a letter of intent with Occidental Petroleum
Corporation, which we refer to as Occidental, to combine the companies' chlor
alkali and related businesses in a partnership. In October 2000, we announced
that the letter of intent had expired. The partnership negotiations were
discontinued primarily due to regulatory issues and certain other matters on
which the parties could not agree.


                                       15

<PAGE>

     On February 8, 1999, we completed the spin-off of our specialty chemicals
businesses as Arch Chemicals, Inc., which we refer to as Arch Chemicals. The
results of operations reflect Arch Chemicals as discontinued operations for the
1999 period presented.

2001 Compared to 2000

     Sales decreased 18% due to lower volumes, metal values and selling prices.
Sales volumes were lower across all segments with the biggest impact coming from
the Metals segment, which was heavily impacted by a soft economy, particularly
in the automotive, electronics and telecommunications industries and to a lesser
extent by the strike at the East Alton, IL facility in the first quarter of
2001. The price decrease was primarily related to lower prices in the Metals and
Winchester segments.

     Gross margin percentage decreased from 18% in 2000 to 12% in 2001 primarily
due to lower sales volumes.

     Selling and administration as a percentage of sales was 9% in 2001 up from
8% in 2000 due to the lower sales base in 2001 as a result of the factors noted
above. Selling and administration was $11 million lower than in 2000 primarily
due to lower incentive compensation costs and fees incurred in 2000 associated
with the discontinued chlor alkali partnership negotiations.

     The decrease in operating results from the non-consolidated affiliates was
due primarily to the lower operating results from the Sunbelt joint venture ($9
million loss in 2001; breakeven in 2000), which was adversely impacted by lower
chlorine pricing.

     In 2001, other income included the gains on the demutualization of
Prudential Insurance of $11 million and on the sale of excess real estate
property of $6 million.

     The effective tax rate decreased to 30.8% from 38.2% due to operating
losses, carryover of foreign tax rate differential and an increase in the
valuation allowance.

2000 Compared to 1999

     In 2000 sales increased 11% due to increased selling prices and volumes and
higher metal values. Selling prices were higher across all segments with the
biggest impact related to higher Electrochemical Unit ("ECU") netbacks (gross
price less freight, discounts, etc.) in the Chlor Alkali Products segment. The
increase in sales volumes was related to the Metals segment.

     Gross margin percentage increased from 13% in 1999 to 18% in 2000 primarily
due to higher ECU prices.

     Selling and administration as a percentage of sales was 8% in 2000, down
from 9% in 1999, due to the higher sales base in 2000 as a result of the factors
noted above. Selling and administration was $5 million higher than in 1999 due
to higher administration expenses, primarily higher incentive compensation costs
and the fees incurred in 2000 associated with the


                                       16

<PAGE>

discontinued chlor alkali partnership negotiations with Occidental, offset in
part by higher pension income.

     The increase in operating results from the non-consolidated affiliates was
due primarily to the improved operating results from the Sunbelt joint venture,
which was favorably impacted by the higher ECU pricing.

     Research and development expenses decreased due to restructuring in the
fourth quarter of 1999 of the process technology department in the Chlor Alkali
Products segment.

     The effective tax rate increased to 38.2% from 37.0%. The increase was
attributable to lower tax benefits related to export sales and increased state
income taxes, partially offset by lower cost of company-owned life insurance
programs and a decrease in the valuation allowance related to state income tax
loss carryforward.

Segment Operating Results

     We define segment operating income as earnings before interest expense,
interest income, other income, restructuring charge and unusual items and income
taxes and include the operating results of non-consolidated affiliates. Segment
operating income includes an allocation of corporate operating expenses. Segment
operating results in 2001 exclude the restructuring charge and unusual items
($42 million, pretax).

               Operating Income (Loss) ........       8      27      (58)


2001 Compared to 2000

     Sales decreased 2% from 2000 primarily due to lower volumes offset in part
by higher ECU netbacks. Our average ECU netbacks in 2001 were approximately
$315, compared to $300 in 2000. The chlor alkali industry participates in
markets, such as vinyls, urethanes and pulp and paper, which have been
negatively impacted by poor economic conditions. These markets have faced
declining demand for their products, which in turn, negatively impacts our
products. Soft demand for chlorine in these markets, caused primarily by the
slowdown in the general economy, has led to reduced chlor alkali operating rates
across the industry. This weak demand forced operating rates to decline to
approximately mid to low 80% from 88% in 2000 and caused an erosion of
chlorine's pricing structure. This contributed to the decline in sales and
operating income in 2001. Also, operating income was lower in 2001 primarily due
to lower sales


                                       17

<PAGE>

volumes, higher manufacturing costs and losses from the Sunbelt joint venture
($9 million loss in 2001; breakeven in 2000) due to lower chlorine prices. The
increased manufacturing costs included higher salt costs and higher fixed cost
absorption due to lower production volumes.

2000 Compared to 1999

     Sales and operating results in 2000 were higher than 1999 primarily due to
higher ECU netbacks and ongoing cost reduction initiatives. Average ECU netbacks
in 2000 were approximately $300, compared to $225 in 1999. While the pricing
cycle improved, demand for chlorine decreased particularly in the second half of
2000, primarily due to the depressed vinyl market. This weak demand along with
higher electricity rates, forced industry operating rates to decline (to
approximately 88% in 2000 down from 95% in 1999), which impacted the
availability of caustic. Caustic demand was high and most suppliers were on
order control or allocation. This tight caustic market supported several price
increases, which more than offset the declining chlorine prices. Higher selling
prices, lower operating costs and improved operating results in 2000 from the
Sunbelt joint venture due to the increase in ECU prices offset the fees
associated with the discontinued chlor alkali partnership negotiations with
Occidental and contributed to the significant improvement in operating income.

Metals

                                                2001      2000     1999
                                               -----     -----    -----
                                                    ($ in millions)
               Sales .......................   $ 618     $ 880    $ 773
               Operating Income ............       7        95       77


2001 Compared to 2000

     Sales decreased 30% due to a significant decline in volumes associated with
the weak economy, offset in part by the sales associated with the Monarch
acquisition. Metals' operating results were significantly lower primarily due to
the economic slowdown, which resulted in substantially lower shipment levels. A
weak economy prevailed all year resulting in a significant reduction of strip
shipments to key market segments of our industry. Automotive, coinage,
electrical connectors, telecommunications (markets served by Olin Aegis, our
business that supplies customized and semi-customized metal packaging for hybrid
integrated circuits and thick ceramic substrates for the electronics market) and
distributor (markets served by Oster, a network of metal service centers),
customers had much lower demand for the industry's products. In addition, the
mill products operations in East Alton, IL took a two-week maintenance shutdown
in 2001, with no similar shutdown in 2000. Also, the strike at our East Alton
facility in the first quarter of 2001 had a moderately adverse impact on Metals'
profits, while the reductions of LIFO inventory quantities in 2001 increased
operating income by approximately $4 million pretax.

                                       18

<PAGE>

2000 Compared to 1999

     Sales in 2000 increased 14% due to increased volumes and higher metal
values and selling prices. Higher volumes and conversion selling prices
increased sales by 9% and higher metal values accounted for 5% of the
improvement. Strip shipments to the coinage, electronics and ammunition segments
were higher in 2000. Oster shipments were higher as well as were those to the
telecommunications market served by Olin Aegis. Shipments of strip to the
automotive and building products markets were lower in 2000. Higher volumes,
improved pricing and a favorable product mix along with the impact from on-going
cost reduction programs more than offset the impact of the work stoppage at East
Alton and contributed to the improvement in operating income.

Winchester

                                           2001        2000         1999
                                          ------      ------       ------
                                                  ($ in millions)
          Sales ........................  $  269      $  277       $  286
          Operating Income .............       7          20           21

2001 Compared to 2000

     Sales in 2001 were slightly lower than 2000 primarily due to lower
international sales. International sales were below last year's levels due to
decreased foreign military business and unfavorable translation of Australian
sales. Domestic commercial sales were comparable to last year despite overall
lower selling prices and the effects of the strike at our East Alton facility in
the first quarter. Our operating income decreased from $20 million in 2000 to $7
million in 2001. The loss of the Lake City government contract (approximately $4
million), the impact of lower domestic commercial prices, higher
personnel-related costs as a result of the new labor agreement at the East Alton
facility and the impact of the strike were the main contributors to this
significant decrease in operating income.

2000 Compared to 1999

     Sales in 2000 were slightly lower than 1999 primarily due to lower domestic
commercial ammunition volumes, offset in part by higher commercial selling
prices. After strong marketplace demand throughout 1999 and the first half of
2000, the market began softening in the third quarter due to an industry-wide
market correction. Operating income declined slightly from 1999 due to several
factors. The impact of the lower volumes, the work stoppage at East Alton,
higher consulting expenses and lower fees from the Lake City Army ammunition
plant



                                       19

more than offset the favorable impact of both higher selling prices and
Australia's improved results from foreign currency translation.

     In 1999, Winchester was the operator of the U.S. Army's Lake City
small-caliber, ammunition plant in Independence, MO. The five-year contract
expired at the end of 1999 and represented approximately $5 million in annual
pretax profits during the year. On July 30, 1999, the Department of the Army
awarded this contract to a competitor. Olin filed a protest to this award. We
did not prevail in our protest of the contract award to operate this plant.
Therefore, our contract to operate that facility terminated at the end of the
first quarter of 2000.

2002 Outlook

     In 2002, interest expense will be higher due to our $200 million 9.125%
Senior Notes offering in December 2001, offset in part by the income from the
temporary investment of funds to be used to retire the $100 million 8% notes
maturing in June 2002. Business conditions in many of our downstream markets
generally remain depressed, but there are a few early signs of recovery. Based
on normal seasonal factors affecting Chlor Alkali and Winchester and the
expected modest improvement in the economy, we anticipate an improvement in our
quarterly results as the year progresses.

     For the first quarter of 2002, we expect that the continued soft economy
will adversely affect our chlorine and caustic pricing resulting in a further
decrease in our ECU prices from 2001 fourth quarter levels. The recent
improvement in EDC (ethylene dichloride - a precursor for polyvinyl chloride or
PVC, a plastic used in applications, such as vinyl siding, plumbing and
automotive parts) pricing and volumes to the Asian markets may lead to higher
chlorine prices. This has resulted in some tightness in chlorine as production
remains constrained by the low demand for caustic. In Metals, our projection for
the first quarter is that overall demand from our customers will not improve
appreciably. There are some signs of improvement but at this point they are not
definitive enough to raise our forecasts for the quarter. For the first quarter
of 2002, Winchester's sales and operating results will likely decrease modestly
from their fourth quarter 2001 levels due to normal seasonal factors.

</TABLE>

     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 our manufacturing locations. Federal legislation providing
for regulation of the manufacture, transportation, use and disposal of hazardous
and toxic substances, and remediation of contaminated sites, 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. We employ waste minimization and pollution prevention programs at our
manufacturing sites.

     We are 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 2001, 2000, and 1999
and may be material to net income in future years. Such charges to income were
$14 million, $15 million and $17 million in 2001, 2000, and 1999 respectively.

     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. Total
environmental-related cash outlays for 2002 are estimated to be $50 million, of
which $27 million is expected to be spent on


                                       21

<PAGE>

investigatory and remedial efforts, $5 million on capital projects and $18
million on normal plant operations. Historically, we have funded our
environmental capital expenditures through cash flow from operations and expect
to do so in the future.

     Our estimated environmental liability at the end of 2001 was attributable
to approximately 60 sites, 18 of which were United States Environmental
Protection Agency ("USEPA") National Priorities List ("NPL") sites. Ten sites
accounted for approximately 73% of the reserve taken for such liabilities and,
of the remaining sites, no one site accounted for more than 2% of our
environmental liability. Two of these ten sites are in the investigatory stage
of the remediation process. In this stage, remedial investigation and
feasibility studies are conducted by us or other potentially responsible parties
(PRPs) and a Record of Decision (ROD) or its equivalent has not been issued. At
four of the ten sites, a ROD or its equivalent has been issued by either the
USEPA or responsible state agency and we either alone, or as a member of a PRP
group, were engaged in performing the remedial measures required by that ROD. At
the remaining four 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.

     Our consolidated balance sheets included liabilities for future
environmental expenditures to investigate and remediate known sites amounting to
$100 million at December 31, 2001, and $110 million at December 31, 2000, of
which $73 million and $85 million were classified as other noncurrent
liabilities, respectively. Those amounts did not take into account any
discounting of future expenditures or any consideration of insurance recoveries
or advances in technology. Those liabilities are reassessed periodically to
determine if environmental circumstances have changed and/or remediation efforts
and our estimate of related costs have changed. As a result of these
reassessments, future charges to income may be made for additional liabilities.

     Annual environmental-related cash outlays for site investigation and
remediation, capital projects, and normal plant operations are expected to range
between approximately $40 million to $50 million over the next several years,
$25 million to $30 million of which is expected to be charged against reserves
recorded on our balance sheet. While we do not anticipate a material increase in
the projected annual level of our 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 PRPs
and our 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 us, which could have a material adverse effect on
our operating results and financial condition. At December 31, 2001, we estimate
we may have additional contingent environmental liabilities of $40 million in
addition to the amounts for which we have already taken a reserve.

     In 2001, income from continuing operations exclusive of non-cash charges,
proceeds from long-term debt borrowings and cash equivalents on hand were used
to finance our working capital requirements, capital and investment projects,
acquisitions, dividends, the purchase of our common stock and debt repayments.

Operating Activities

     In 2001, the decrease in cash provided by operating activities of
continuing operations was primarily attributable to lower operating results. In
2001, there was no investment in working capital. Whereas in 2000, our
investment in working capital increased commensurate with the increase in sales
and operating results compared to 1999. In 2001, the reduced accounts receivable
and inventory levels more than offset the impact of the liquidation of higher
2000 year-end accounts payable and accrued liability balances. The accounts
receivable and inventory levels are lower than normal primarily due to the lower
volume of Metals business resulting from the impact of the soft economy on its
markets and the declining prices and volumes in our chlor alkali business.

     In 2000, the increase in cash flow from operating activities of continuing
operations from 1999 was primarily attributable to higher operating income and a
lower investment in working capital, which included a tax refund. In 2000, we
received approximately $19 million as a result of a tax refund.

Capital Expenditures

     Capital spending in 2001 of $65 million was 32% lower than 2000. The
capital spending decrease was primarily due to completion of projects that were
begun in 2000, primarily to


                                       23

<PAGE>

expand production capacity in Metals higher value-added product categories, in
particular high performance alloys. These products are patented, specialty
copper alloys that provide value-added benefits to global customers in the
computer, telecommunications and automotive industries. This expansion was
completed in the second half of 2001 with the majority of the spending occurring
in 2000. Capital spending in 2001 was approximately 76% of depreciation compared
to 120% in 2000.

     Capital spending in 2000 of $95 million was 30% higher than 1999. The
capital spending increase was primarily in the Metals segment to expand
production capacity in its higher value-added product categories, in particular
high performance alloys. Capital spending in 2000 was approximately 120% of
depreciation compared to 95% in 1999.

     In 2002, we plan to manage our capital spending at a level approximating
50% of depreciation or about $40 million.

Investing Activities

     In June 2001, we acquired the stock of Monarch for approximately $48
million. Monarch was a privately held, specialty brass manufacturer
headquartered in Waterbury, CT, with revenues of approximately $95 million in
2000. It produces and distributes an array of high performance copper alloys and
other materials used for applications in electronics, telecommunications,
automotive products and building products. We financed the purchase price
through our credit facilities. The purchase price exceeded the fair value of the
identifiable net assets acquired by $19 million.

     During 1999, the Company completed the purchase of a manufacturer of
microelectronic packages in England and a metal distribution company in Puerto
Rico for a total of $3 million.

Financing Activities

     At December 31, 2001, we had an unsecured revolving credit agreement with a
group of banks with commitments totaling $165 million, all of which was
available at December 31, 2001 and 2000. In addition in 2001, we had a $25
million line of credit with another bank, none of which was used. On January 3,
2002, we entered into a new three-year senior revolving credit facility of $140
million, including a sublimit for letters of credit. The new facility replaces
our existing credit facilities and will expire on January 3, 2005. We may select
various floating rate borrowing options. The senior credit facility includes
various customary restrictive covenants, including restrictions related to the
ratio of debt to earnings before interest expense, taxes, depreciation and
amortization ("leverage ratio") and the ratio of earnings before interest
expense, taxes, depreciation and amortization to interest expense ("coverage
ratio"). In the event that the leverage ratio equals or exceeds 3.75, we are
required under this senior credit facility to grant a security interest in all
of our U.S. inventory and accounts receivables. No assets of our subsidiaries
will secure our obligation under our senior credit facility.


                                       24

<PAGE>

     In December 2001, we sold $200 million of 9.125% Senior Notes with a
maturity date of December 15, 2011. We used a portion of the net proceeds of the
offering to repay our short-term indebtedness and plan to use $100 million to
repay the 8% notes due in June 2002. Any remaining proceeds will be available
for general corporate purposes.

     Prior to the spin-off of Arch Chemicals in February 1999, we borrowed $75
million under a credit facility which liability was assumed by Arch Chemicals.
We used these funds for general corporate purposes, which included share
repurchases.

     During 2001, 2000 and 1999, we used $14 million, $20 million and $11
million to repurchase 0.7 million, 1.2 million and 0.9 million shares of our
stock, respectively. Our board of directors has approved two share repurchase
programs to repurchase a total of 10 million shares of our outstanding common
stock. Approximately 298,000 shares remain to be repurchased under these
programs.

     The percent of total debt to total capitalization increased to 61% at
December 31, 2001, from 41% at year-end 2000 and was 43% at year-end 1999. The
increase in 2001 from year-end 2000 was due to the issuance of our 9.125% Senior
Notes and lower shareholders' equity at December 31, 2001.

     Dividends per common share were $0.80 in 2001 and 2000 and $0.90 in 1999.
Total dividends paid on common stock amounted to $35 million in 2001, $36
million in 2000 and $41 million in 1999. In 2001 and 2000, we paid a quarterly
dividend of $0.20 per share. Prior to the spin-off of Arch Chemicals, we paid a
first quarter 1999 dividend of $0.30 per share. Following the distribution of
Arch Chemicals, the quarterly dividend was reduced to $0.20 per share to reflect
the effect of the distribution.

     The payment of cash dividends is subject to the discretion of our board of
directors and will be determined in light of then-current conditions, including
our earnings, our operations, our financial condition, our capital requirements
and other factors deemed relevant by our board of directors. In the future, our
board of directors may change our dividend policy, including the frequency or
amount of any dividend, in light of then-existing conditions.



LIQUIDITY AND OTHER FINANCING ARRANGEMENTS

     Our principal sources of liquidity are from cash and cash equivalents,
short-term investments, cash flow from operations, short-term borrowings under a
senior revolving credit facility and other financing arrangements. We also
have access to the debt and equity markets.

     Cash flow from operations is subject to change as a result of the cyclical
nature of our operating results, which have been affected recently by economic
cycles and resulting downturn in many of the industries served by us, such as
automotive, electronics and the telecommunications markets. In addition, cash
flow from operations is affected by considerable changes in ECU prices caused by
the changes in the supply/demand balance, resulting in the chlor alkali business
having tremendous leverage on our earnings. A $10 per ECU price change equates
to an $11 million pretax profit change when operating at full capacity.

     Our current debt structure is used to fund our business operations and
commitments from banks under our revolving credit facility are a source of
liquidity. As of December 31, 2001, we



                                       25

<PAGE>

had long-term borrowings of $431 million of which $86 million was at variable
rates. We have interest rate swaps to hedge underlying debt obligations. Annual
maturities of long-term debt are $102 million in 2002; $2 million in 2003; $27
million in 2004; $63 million in 2005, $1 million in 2006 and $236 million
thereafter. We plan to use a portion of net proceeds from the offering of our
$200 million 9.125% Senior Notes to repay the $100 million 8% notes due in June
2002.

     Our total debt to capitalization ratio increased to 61% at December 31,
2001, from 41% at year-end 2000, and was 43% at year-end 1999. The increase in
2001 from year-end 2000 was due to the new 9.125% Senior Notes and lower
shareholders' equity at December 31, 2001.

     We use operating leases for certain properties, such as railroad cars,
distribution, warehousing and office space, data processing and office
equipment. 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. Future minimum rent payments
under operating leases having initial or remaining non-cancelable lease terms in
excess of one year at December 31, 2001 are as follows: $21 million in 2002; $20
million in 2003; $18 million in 2004; $16 million in 2005; $15 million in 2006
and $61 million thereafter. Assets under capital leases are not significant.

     On December 31, 1997, we entered into a long-term, sulfur dioxide supply
agreement with Alliance Specialty Chemicals, Inc. ("Alliance"), formerly known
as RFC SO2, Inc. Alliance has the obligation to deliver annually 36,000 tons of
sulfur dioxide. Alliance owns the sulfur dioxide plant, which is located at our
Charleston, TN facility and is operated by us. The price for the sulfur dioxide
is fixed over the life of the contract. In addition, we are obligated to make a
monthly payment of approximately $200 thousand to an outside third party.
Commitments related to this agreement are approximately $2 million per year for
each year of 2002 through 2006 and $12 million thereafter.

     We utilize a credit facility, standby letters of credit and guarantees. In
January 2002, we entered into a new senior revolving credit facility with a
group of banks. This credit facility is described above under the caption,
"Financing Activities". As of March 1, 2002, we did not have any outstanding
borrowings under this credit facility.

     At December 31, 2001, we had outstanding standby letters of credit of $49
million. These letters of credit were used to support certain long-term debt
obligations.

     We and our partner, PolyOne Corporation ("PolyOne") own equally the Sunbelt
Chlor Alkali Partnership ("Sunbelt joint venture"). The partnership owns assets
with productive capability to manufacture 275 thousand tons of caustic soda and
250 thousand tons of chlorine on an annual basis. We market all of the caustic
soda production for the venture, while all of the chlorine production is
required to be purchased by Oxy Vinyls (a joint venture between OxyChem and
PolyOne) based on a formula tied to the market price of chlorine. The
construction of this plant and equipment was financed by the issuance of $195
million of Guaranteed Secured Senior Notes due 2017. The Sunbelt joint venture
sold $97.5 million of Guaranteed Secured Senior


                                       26

<PAGE>

Notes due 2017, Series O, and $97.5 million of Guaranteed Secured Senior Notes
due 2017, Series G. We refer to these notes as the Sunbelt Notes. The Sunbelt
Notes bear interest at a rate of 7.23% per annum payable semiannually in arrears
on each June 22 and December 22.

     We have guaranteed Series O of the Sunbelt Notes, and PolyOne has
guaranteed Series G of the Sunbelt Notes, in both cases pursuant to customary
guaranty agreements. Our guarantee and PolyOne's guarantee are separate, rather
than joint. In other words, we are not required to make any payments to satisfy
the indebtedness of PolyOne. An insolvency or bankruptcy of PolyOne will not
automatically trigger acceleration of the Sunbelt Notes or cause us to be
required to make payments under our guarantee, even if PolyOne is required to
make payments under its guarantee. However, if the Sunbelt joint venture does
not make timely payments on the Sunbelt Notes, whether as a result of a failure
to pay on a guarantee or otherwise, the holders of the Sunbelt Notes may proceed
against the assets of the Sunbelt joint venture for repayment.

     Beginning on December 22, 2002 and each year thereafter, our Sunbelt joint
venture is required to repay approximately $12 million of the Sunbelt Notes, of
which approximately $6 million is attributable to Series O of the Sunbelt Notes.
In the event our Sunbelt joint venture cannot make any of these payments, we
would be required to fund our half of such payment. In certain other
circumstances, we may also be required to repay the Sunbelt Notes prior to their
maturity. We and PolyOne have agreed that, if we or PolyOne intend to transfer
our respective interests in the Sunbelt joint venture and the transferring party
is unable to obtain consent from holders of 80% of the aggregate principal
amount of the indebtedness related to the guarantee being transferred after good
faith negotiations, then we and PolyOne will be required to repay our respective
portions of the Sunbelt Notes. In such event, any make whole or similar
penalties or costs will be paid by the transferring party.

Critical Accounting Policies and Estimates

     Our discussion and analysis of our financial condition and results of
operations are based upon our consolidated financial statements, which have been
prepared in accordance with accounting principles generally accepted in the
United States. The preparation of these financial statements requires us to make
estimates and judgments that affect the reported amounts of assets, liabilities,
sales and expenses, and related disclosure of contingent assets and liabilities.
Significant estimates in our consolidated financial statements include
environmental, restructuring and other unusual items, litigation, income tax
reserves including deferred tax asset valuation allowance, pension,
postretirement and other benefits and allowance for doubtful accounts. We base
our estimates on prior experience, facts and circumstances and other assumptions
that we believe to be reasonable. Actual results may differ from these
estimates.


     We believe the determination of our environmental cost accruals is a
critical accounting policy. Accruals for environmental matters are recorded when
it is probable that a liability has been incurred and the amount of the
liability can be reasonably estimated, based upon current law and existing
technologies. These amounts, which are not discounted and are exclusive of
claims against third parties, are adjusted periodically as assessments and
remediation efforts progress or additional technical or legal information
becomes available.


                                       27

     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 our 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
us, which could have a material adverse effect on our operating results and
financial condition.

New Accounting Standards

     As of January 1, 2001, we adopted Statement of Financial Accounting
Standards, ("SFAS"), No. 133, "Accounting for Derivative Instruments and Hedging
Activities," as amended by SFAS No. 137 and No. 138. See our description of
Derivative Financial Instruments below for additional information.

     During the third quarter of 2001, the Financial Accounting Standards Board,
("FASB"), issued SFAS No. 141, "Business Combinations," and SFAS No. 142,
"Goodwill and Other Intangible Assets." SFAS No. 141 requires that the purchase
method of accounting be used for all business combinations initiated after June
30, 2001. SFAS No. 141 also specifies criteria that intangible assets acquired
in a purchase method business combination must meet to be recognized and
reported apart from goodwill. SFAS No. 142 requires that goodwill and intangible
assets with indefinite useful lives no longer be amortized, but instead tested
for impairment at least annually in accordance with the provisions of this
statement. Goodwill amortization for the year ended December 31, 2001 was
approximately $2 million. SFAS No. 142 also requires that intangible assets with
estimable useful lives be amortized over their respective estimated useful lives
to their estimated residual values, and reviewed for impairment in accordance
with SFAS No. 121, "Accounting for the Impairment of Long-Lived Assets and for
Long-Lived Assets to Be Disposed Of." The adoption of these statements will
increase pretax income by approximately $2 million, resulting from the
elimination of goodwill amortization and will not have a material impact on our
financial statements.

     The FASB issued SFAS No. 143, "Accounting for Asset Retirement
Obligations." SFAS No. 143 requires that the fair value of a liability for an
asset retirement be recognized in the period in which it is incurred if a
reasonable estimate of fair value can be made. The associated asset retirement
costs are capitalized as part of the carrying amount of the long-lived asset.
This statement is effective for fiscal years beginning after June 30, 2002. At
this time, it is not practical to reasonably estimate the impact of adopting
this statement on our financial statements.

     The FASB issued SFAS No. 144, "Accounting for Impairment or Disposal of
Long-Lived Assets." SFAS No. 144 addresses the financial accounting and
reporting for the impairment or disposal of long-lived assets. This statement
requires that one accounting model be used for long-lived assets to be disposed
of by sale whether previously held and used or newly acquired.

                                       28

<PAGE>

In addition, it broadened the presentation of discontinued operations to include
more disposal transactions. This statement is effective for fiscal years
beginning after December 15, 2001, and interim periods within those fiscal
years. At this time, we believe that the adoption of this statement will not
have a material impact on our financial statements.

Derivative Financial Instruments

     In 1998, the FASB issued Statement No. 133 "Accounting for Derivative
Instruments and Hedging Activities." It requires an entity to recognize all
derivatives as either assets or liabilities in the statement of financial
position and measure those instruments at fair value. The implementation date of
this statement is effective for all fiscal quarters of fiscal years beginning
after June 15, 2000. We adopted FASB No. 133 on January 1, 2001, and will
achieve hedge accounting treatment for substantially all of our business
transactions whose risks are covered using derivative instruments. SFAS No. 133
requires that all derivative instruments be recorded on the balance sheet at
their fair value. The accounting treatment of changes in fair value is dependent
upon whether or not a derivative instrument is designated as a hedge and, if so,
the type of hedge. For derivatives designated as a fair value hedge, the changes
in the fair value of both the derivative and the hedged item are recognized in
earnings. For derivatives designated as a cash flow hedge, the change in fair
value of the derivative is recognized in other comprehensive income until the
hedged item is recognized in earnings. Ineffective portions are recognized
currently in earnings. Unrealized gains and losses on derivatives not qualifying
for hedge accounting are recognized currently in earnings. Upon adoption of this
statement, we recorded on January 1, 2001, assets totaling $1.2 million and
liabilities totaling $2.1 million with an offsetting entry to Accumulated Other
Comprehensive Income (Loss). The new standard does not allow for the hedge
accounting treatment on the portion of any hedge that is not effective. The
ineffectiveness, which was recorded at January 1, 2001, was a loss of less than
$0.1 million.

     Previously, we accounted for forward contracts to buy and sell foreign
currencies under SFAS No. 52, "Foreign Currency Translation" and futures
contracts to reduce the impact of metal price fluctuations under SFAS No. 80,
"Accounting for Futures Contracts." At December 31, 2001, we had no forward
contracts to buy or sell foreign currencies. At December 31, 2000, we had
forward contracts to sell foreign currencies with a face value of $4 million
(which approximates carrying value) and no forward contracts to buy foreign
currencies. Foreign currency exchange gains (losses), net of taxes, were less
than $(1) million in 2001, less than $1 million in 2000 and less than $(1)
million in 1999. At December 31, 2001, we had open positions in futures
contracts totaling $47 million (2000 - $27 million). If the futures contracts
had been settled on December 31, 2001, we would have recognized a loss of $1
million. Gains (losses) on futures contracts, net of taxes, were $(6) million in
2001, less than $1 million in 2000 and $1 million in 1999.

     We use cash flow hedges of commodities such as copper, zinc, nickel and
lead to provide a measure of stability in managing our exposure to price
fluctuations. We also use fair value hedges of interest rate swaps as a means of
hedging changes in interest rates on our outstanding debt obligations.


                                       29

<PAGE>

     At December 31, 2001, Accumulated Other Comprehensive Income (Loss)
included a pretax decline in fair value of $3 million. In addition, the
unfavorable ineffective portion of changes in fair value resulted in a $1
million charge to earnings for the year ended December 31, 2001. Offsetting the
above, there were assets totaling $1 million and liabilities of $5 million.

     Our foreign currency contracts and certain commodity derivatives did not
meet the criteria of SFAS No. 133 to qualify for hedge accounting. The
cumulative effect of items not qualifying for hedge accounting for 2001 was not
material to earnings.

Risk Management

     We periodically evaluate 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, our
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 we operate.

Item 7A.  Quantitative and Qualitative Disclosures About Market Risk

     We are exposed to market risk in the normal course of our business
operations due to our operations in different foreign currencies, our purchases
of certain commodities, and our ongoing investing and financing activities. The
risk of loss can be assessed from the perspective of adverse changes in fair
values, cash flows and future earnings. We have established policies and
procedures governing our management of market risks and the use of financial
instruments to manage exposure to such risks.

     Certain raw materials, namely copper, lead, and zinc used primarily in our
Metals and Winchester segments products are subject to price volatility.
Depending on market conditions, we may enter into futures contracts and put and
call option contracts in order to reduce the impact of metal price fluctuations.
As of December 31, 2001, we maintained open positions on futures contracts
totaling $47 million. Assuming a hypothetical 10% increase in commodity prices,
which are currently hedged, we would experience a $4.7 million increase in our
cost of inventory purchased, which would be offset by a corresponding increase
in the value of related hedging instruments.

     We are exposed to changes in interest rates primarily as a result of our
investing and financing activities. Investing activity is not material to our
consolidated financial position, results of operations, or cash flow. Our
current debt structure is used to fund business operations and commitments from
banks under our revolving credit facility are a source of liquidity. As of


                                       30

<PAGE>

December 31, 2001, we had long-term borrowings of $431 million of which $86
million are at variable rates. We have interest rate swaps to hedge underlying
debt obligations. We swapped interest payments on $50 million principal amount
of our 9.125% Senior Notes to a floating rate (5.55125% at December 31, 2001).
In February 2002, we swapped interest payments on $30 million principal amount
of our 9.125% Senior Notes to an estimated floating rate of 5.68%. During 1992,
we swapped interest payments on $50 million principal amount of our 8% notes due
2002, to a floating rate (1.91375% at December 31, 2001). In June 1995, we
offset this transaction by swapping interest payments to a fixed rate of 6.485%.

     If the actual change in interest or commodities pricing is substantially
different than expected, the net impact of interest rate risk or commodity risk
on our cash flow may be materially different than that disclosed above.

     We do not enter into any derivative financial instruments for speculative
purposes.

Item 8.  CONSOLIDATED FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

                    MANAGEMENT REPORT ON FINANCIAL STATEMENTS

     Management is responsible for the preparation and integrity of the
accompanying consolidated financial statements. These financial statements have
been prepared in conformity with generally accepted accounting principles and,
where necessary, involve amounts based on management's best judgments and
estimates. Management also prepared the other information in this annual report
and is responsible for its accuracy and consistency with the financial
statements.

     The Company's system of internal controls is designed to provide reasonable
assurance as to the integrity and reliability of the financial statements, the
protection of assets from unauthorized use or disposition, and the prevention
and detection of fraudulent financial reporting. This system, which is reviewed
regularly, consists of written policies and procedures, an organizational
structure providing delegation of authority and segregation of responsibility
and is monitored by an internal audit department. The Company's independent
auditors also review and test the internal control system along with tests of
accounting procedures and records to the extent that they consider necessary in
order to issue their opinion on the financial statements. Management believes
that the system of internal accounting controls meets the objectives noted
above.

     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. These expectations are
summarized in a document entitled "Our Values and Standards of Business Conduct"
which is distributed to every employee. The standards, which are also
periodically reinforced through personal training sessions, address 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. In addition, the Company maintains a systematic program
to assess compliance with these standards and has established various outlets,
including a confidential telephone help-line (1-800-362-8348), for employees and
suppliers to ask questions and share concerns.

     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
accounting, auditing, internal controls and financial reporting matters. The
Audit Committee annually recommends to the Board of Directors the appointment of
independent auditors, subject to shareholder approval. The independent auditors
and the Company's internal audit department have independent and free access to
the Audit Committee.

                          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, 2001 and 2000 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, 2001. 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 auditing standards generally
accepted in the United States of America. 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, 2001 and 2000, and the results
of their operations and their cash flows for each of the years in the three-year
period ended December 31, 2001 in conformity with accounting principles
generally accepted in the United States of America.

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

Accounting Policies

     The preparation of the consolidated financial statements requires estimates
and assumptions that affect amounts reported and disclosed in the financial
statements and related notes. Actual results could differ from those estimates.

     Basis of Presentation

     The consolidated financial statements include the accounts of Olin
Corporation and all majority-owned subsidiaries. Investments in 20-50% owned
affiliates are accounted for on the equity method. Accordingly, we include only
our share of earnings or losses of these affiliates in consolidated net income.

     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 included in Accumulated Other Comprehensive Income (Loss). Where foreign
affiliates operate in highly inflationary economies, non-monetary amounts are
translated at historical exchange rates while monetary assets and liabilities
are translated at the current rate with the related adjustments reflected in the
Consolidated Statements of Income.

     Cash and Cash Equivalents

     All highly liquid investments, with a maturity of three months or less at
the date of purchase, are considered to be cash equivalents.

     Short-Term Investments

     Marketable securities are accounted for in accordance with Statement of
Financial Accounting Standards ("SFAS") No. 115, "Accounting for Certain
Investments in Debt and Equity Securities." We have classified our marketable
equity securities as available-for-sale which are reported at fair market value
with unrealized gains and losses included in Shareholders' Equity net of
applicable taxes. The fair value of marketable securities is determined by
quoted market prices. Unrealized gains in 2001 were $1; unrealized gains and
losses in 2000 were insignificant. Realized gains and losses on sales of
investments, as determined on the specific identification method and declines in
value of securities judged to be other-than-temporary are included in Other
Income in the Consolidated Statements of Income. Interest and dividends on all
securities are included in Interest Income and Other Income, respectively.

     All investments which have maturities between three and twelve months at
purchase, are considered short-term investments and consist of debt securities
such as commercial paper, time deposits, certificates of deposit, bankers
acceptances, repurchase agreements, and marketable direct obligations of the
United States Treasury and its agencies.

     Inventories

     Inventories are valued principally by the dollar value last-in, first-out
(LIFO) method of inventory accounting; such valuations are not in excess of
market. Cost for other inventories has been determined principally by the
average-cost and first-in, first-out (FIFO) methods. Elements of costs in
inventories include raw materials, direct labor and manufacturing overhead.

                                       39

<PAGE>

     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 shorter. Start-up costs
are expensed as incurred.

     Comprehensive Income

     We calculated comprehensive income in accordance with SFAS No. 130,
"Reporting Comprehensive Income." Accumulated Other Comprehensive Income (Loss)
at December 31, 2001 includes cumulative translation losses of $12 ($11 at
December 31, 2000), minimum pension liability of $5 ($5 at December 31, 2000)
and other unrealized losses of $1. We do not provide for U.S. income taxes on
foreign currency translation adjustments since we do not provide for such taxes
on undistributed earnings of foreign subsidiaries.

     Goodwill

     Goodwill, the excess of the purchase price of the acquired businesses over
the fair value of the respective net assets, is amortized principally over 30
years on a straight-line basis. We periodically review the value of our goodwill
to determine if any impairment has occurred. We assess the potential impairment
of recorded goodwill and other long-lived assets by comparing the undiscounted
value of expected future operating cash flows in relation to the book value of
the goodwill and related long-lived assets. An impairment would be recorded
based on the estimated fair value.

     During the third quarter of 2001, Financial Accounting Standards Board
("FASB"), issued SFAS No. 142, "Goodwill and Other Intangible Assets". SFAS No.
142 requires that goodwill and intangible assets with indefinite useful lives no
longer be amortized, but instead tested for impairment at least annually in
accordance with the provisions of this statement. Goodwill amortization for the
year ended December 31, 2001 was approximately $2. SFAS No. 142 also requires
that intangible assets with estimable useful lives be amortized over their
respective estimated useful lives to their estimated residual values, and
reviewed for impairment in accordance with SFAS No. 121, "Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of."
Commencing January 1, 2002, we will no longer amortize goodwill and will adopt
the provision of SFAS No. 142.

     Environmental Liabilities and Expenditures

     Accruals for environmental matters are recorded when it is probable that a
liability has been incurred and the amount of the liability can be reasonably
estimated, based upon current law and existing technologies. These amounts,
which are not discounted and are exclusive of claims against third parties, are
adjusted periodically as assessment and remediation efforts progress or
additional technical or legal information becomes available. Environmental
remediation costs are charged to expense as incurred. Environmental costs are
capitalized if the costs increase the value of the property and/or mitigate or
prevent contamination from future operations.

     Income Taxes

     Deferred taxes are provided 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.

     Derivative Financial Instruments

     In 1998, the FASB issued SFAS No. 133 "Accounting for Derivative
Instruments and Hedging Activities." It requires an entity to recognize all
derivatives as either assets or liabilities in the statement of financial
position and measure those instruments at fair value. The implementation date of
this statement is effective for all fiscal quarters of fiscal years beginning
after June 15, 2000. We adopted SFAS No. 133 on January 1, 2001, and will
achieve hedge accounting treatment for substantially all of our business
transactions whose risks are covered using derivative instruments. The hedge
accounting treatment provides for the deferral of gains or losses on derivative
instruments until such time as the related transactions occur. Upon adoption of
this statement, we recorded on January 1, 2001, assets totaling $1.2 and
liabilities totaling $2.1 with an offsetting entry to Accumulated Other
Comprehensive Income (Loss). The new standard does not allow for hedge
accounting treatment on the portion of any hedge that is not effective. The
ineffectiveness, which was recorded at January 1, 2001 was a loss of less than
$0.1.

     Previously, we accounted for forward contacts to buy and sell foreign
currencies under SFAS No. 52, "Foreign Currency Translation" and futures
contracts to reduce the impact of metal price fluctuations under SFAS No. 80,
"Accounting for Futures Contracts." At December 31, 2001, we had no forward
contracts to buy or sell foreign currencies. At December 31, 2000, we had
forward contracts to sell foreign currencies with a face value of $4 (which
approximates carrying value) and no forward contracts to buy foreign currencies.
Foreign currency exchange gains (losses), net of taxes, were less than $(1) in
2001, less than $1 in 2000 and less than $(1) in 1999. At December 31, 2001, we
had open positions in futures contracts totaling $47 (2000-$27). If the futures
contracts had been settled on December 31, 2001, we would have recognized a loss
of $1. Gains (losses) on futures contracts, net of taxes, were $(6) in 2001,
less than $1 in 2000 and $1 in 1999.

     We use cash flow hedges of commodities such as copper, zinc, nickel and
lead to provide a measure of stability in managing our exposure to price
fluctuations. We also use fair value hedges of interest rate swaps as a means of
hedging changes in interest rates on our outstanding debt obligations.

     At December 31, 2001, Accumulated Other Comprehensive Income (Loss)
included a pretax decline in fair value of $3. In addition, the unfavorable
ineffective portion of changes in fair value resulted in a $1 charge to earnings
for the year ended December 31, 2001. Offsetting the above, there were assets
totaling $1 and liabilities of $5.

     Our foreign currency contracts and certain commodity derivatives did not
meet the criteria of SFAS No. 133 to qualify for hedge accounting. The
cumulative effect of items not qualifying for hedge accounting for the year 2001
was not material to earnings.

     Financial Instruments

     The carrying values of cash and cash equivalents, accounts receivable and
accounts payable approximated fair values due to the short-term maturities of
these instruments. The fair value of our long-term debt was determined based on
current market rates for debt of the same risk and maturities. At December 31,
2001, the estimated fair value of debt was $432 (2000-$231). The fair values of
currency forward contracts were estimated based on quoted market prices for
contracts with similar terms.

     Stock-Based Compensation

     We account for stock-based compensation under SFAS No. 123, "Accounting for
Stock-Based Compensation." As allowed under SFAS No. 123, we have chosen to
continue to account for stock-based compensation cost in accordance with
Accounting Principles Board Opinion ("APB") No. 25, "Accounting for Stock Issued
to Employees." Under this opinion, compensation cost is recorded when the fair
market value of our stock at the date of grant for fixed options exceeds the
exercise price of the stock option. Our policy is to

                                       41

<PAGE>

grant stock options at the fair market value of our common stock on the date of
the grant. Compensation cost for restricted stock awards is accrued over the
life of the award based on the quoted market price of our stock at the date of
the award.

Earnings Per Share

     Basic earnings (loss) per share are computed by dividing net income (loss)
by the weighted average number of common shares outstanding. Diluted earnings
per share reflect the dilutive effect of stock options (refer to footnote called
"Stock Options").

     Our Board of Directors approved two share repurchase programs to repurchase
a total of 10 million shares of our outstanding common stock. During 2001, 2000
and 1999 we repurchased 0.7 million, 1.2 million and 0.9 million shares,
respectively. Approximately 298,000 shares remain to be repurchased under these
programs.

Short-Term Investments

     Short-term investments, which approximate fair value, were $37 and $25 at
December 31, 2001 and 2000, respectively, and represented the equity value of
the company-owned life insurance programs and in 2001 included equity shares
resulting from the non-cash Prudential demutualization.

Trade Receivables

     Allowance for doubtful items was $7 at December 31, 2001 and 2000.
Provisions charged to operations were $2 in 2001 and 2000 and less than $1 in
1999. Bad debt write-offs, net of recoveries, were $2 in 2001, $1 in 2000 and
less than $1 in 1999.

     Pursuant to a note purchase agreement dated December 22, 1997, the Sunbelt
joint venture sold $97.5 of Guaranteed Secured Senior Notes Due 2017, Series O,
and $97.5 of Guaranteed Secured Senior Notes Due 2017, Series G. We refer to
these notes as the Sunbelt Notes. The Sunbelt Notes bear interest at a rate of
7.23% per annum, payable semiannually in arrears on each June 22 and December
22.

     We have guaranteed Series O of the Sunbelt Notes, and PolyOne Corporation
("PolyOne"), our partner in this venture, has guaranteed Series G of the Sunbelt
Notes, in both cases pursuant to customary guarantee agreements. Our guarantee
and PolyOne's guarantee are separate, rather than joint. In other words we are
not required to make any payments to satisfy the indebtedness of PolyOne. An
insolvency or bankruptcy of PolyOne will not automatically trigger acceleration
of the Sunbelt Notes or cause us to be required to make payments under our
guarantee, even if PolyOne is required to make payments under its guarantee.
However, if the Sunbelt joint venture does not make timely payments on the
Sunbelt Notes, whether as a result of a failure to pay on a guarantee or
otherwise, the holders of the Sunbelt Notes may proceed against the assets of
the Sunbelt joint venture for repayment.

     Beginning on December 22, 2002 and each year thereafter, our Sunbelt joint
venture is required to repay approximately $12 of the Sunbelt Notes, of which
approximately $6 is attributable to Series O of the Sunbelt Notes. In the event
our Sunbelt joint venture cannot make any of these payments, we would be
required to fund our half of such payment. In certain other circumstances, we
may also be required to repay the Sunbelt Notes prior to their maturity. We and
PolyOne have agreed that, if we or PolyOne intend to transfer our respective
interests in the Sunbelt joint venture and the transferring party is unable to
obtain consent from holders of 80% of the aggregate principal amount of the
indebtedness related to the guarantee being transferred after good faith
negotiations, then we and PolyOne will be required to repay our respective
portions of the Sunbelt Notes. In such event, any make whole or similar
penalties or costs will be paid by the transferring party.

Short-Term Borrowings

     At December 31, 2001, we had an unsecured revolving credit agreement with a
group of banks with commitments totaling $165, all of which was available at
December 31, 2001 and 2000. In addition, we had a $25 credit facility with
another bank, none of which was used. On January 3, 2002, we entered into a new
three-year senior revolving credit facility of $140, including a sublimit for
letters of credit. The new facility replaces our existing credit facilities and
will expire on January 3, 2005. We may select various floating rate borrowing
options. The senior credit facility includes various customary restrictive
covenants including restrictions related to the ratio of debt to earnings before
interest expense, taxes, depreciation and amortization ("leverage ratio") and
the ratio of earnings before interest expense, taxes, depreciation and
amortization to interest expense ("coverage ratio"). In the event that the
leverage ratio equals or exceeds 3.75, we are required under this senior credit
facility to grant a security interest in all of our U.S. inventory and accounts
receivables. No assets of our subsidiaries will secure our obligation under our
senior credit facility.

     In December 2001, we sold $200 of 9.125% Senior Notes Due 2011 with a
maturity date of December 15, 2011. We used a portion of the net proceeds of
this offering to repay our short-term indebtedness and plan to use $100 to repay
the 8% notes due in June 2002. Any remaining proceeds will be available for
general corporate purposes. In February 2002, we swapped interest payments on
$30 principal amount of our 9.125% Senior Notes to an estimated floating rate of
5.68%.

     In December 2001, we swapped interest payments on $50 principal amount of
our 9.125% Senior Notes due 2011 to a floating rate (5.55125% at December 31,
2001). During 1992, we swapped interest payments on $50 principal amount of the
8% notes due 2002 to a floating rate (1.91375% at December 31, 2001). In June
1995, we offset this transaction by swapping interest payments to a fixed rate
of 6.485%. The difference between interest paid and interest received is
included as an adjustment to interest expense. A settlement of the fair market
value of the interest rate swaps as of December 31, 2001 would result in a cost
of less than $1. Counter-parties to interest rate swap contracts are major
financial institutions. Our loss in the event of nonperformance by a
counter-party is not significant.

     At December 31, 2001, there remained $48 unissued under the medium-term
note program registered in May 1994.

     Annual maturities of long-term debt are $102 in 2002, $2 in 2003, $27 in
2004, $63 in 2005, $1 in 2006 and $236 thereafter.

     Interest expense incurred on short-term borrowings and long-term debt
totaled $18 in 2001, $17 in 2000 and $16 in 1999; of which $1 was capitalized in
2001 and 2000.

Pension Plans and Retirement Benefits

     Essentially all of our domestic pension plans are non-contributory
final-average-pay or flat-benefit plans and all domestic employees are covered.
Our funding policy is consistent with the requirements of federal laws and
regulations. We provide certain postretirement health care and life insurance
benefits for eligible active and retired domestic employees.

   Our common stock represented approximately 1% of the plan assets at December
31, 2001 and 2000, respectively.

   Our foreign subsidiaries maintain pension and other benefit plans, which are
consistent with statutory practices and are not significant.

   Our pension plan provides that if, within three years following a change of
control of Olin, any corporate action is taken or filing made in contemplation
of, among other things, a plan termination or merger or other transfer of assets
or liabilities of the plan, and such termination, merger or transfer thereafter
takes place, plan benefits would automatically be increased for affected
participants (and retired participants) to absorb any plan surplus.

   The accumulated postretirement benefit obligation was determined using the
projected unit credit method and an assumed discount rate of 7.5% in 2001 and
7.75% in 2000. The assumed health care cost trend rate used for pre-65 retirees
was 5.75% in 2001, 6.5% in 2000 and 7.5% in 1999, declining one-half percent per
annum to 5%. For post-65 retirees, we provide a fixed dollar benefit, which is
not subject to escalation.

   Assumed health care cost trend rates have a significant effect on the amounts
reported for the postretirement health care plan. A one-percentage-point
increase (decrease) in assumed health care cost trend rates would have a less
than $1 increase (decrease) in total service and interest cost components and a
$2 increase (decrease) in the postretirement benefit obligation.

   Included in Other Current Assets at December 31, 2001 and 2000 are $35 and
$29, respectively, of net current deferred assets. The deferred tax provision
for 2001 does not reflect the tax effect of $1 resulting from hedging activity
under SFAS No. 133 or $4 resulting from the acquisition of Monarch. For the year
2000, the deferred tax provision does not reflect $2 resulting from additional
minimum pension liability adjustment required by SFAS No. 87, "Employers
Accounting for Pensions."

     Realization of the net deferred tax assets is dependent on future reversals
of existing taxable temporary differences and adequate future taxable income,
exclusive of reversing temporary differences and carryforwards. Although
realization is not assured, we believe that it is more likely than not that the
net deferred tax assets will be realized.

     We have state net operating loss carryforwards of approximately $123, which
are available to offset future state taxable income, if any, through 2014. We
also have minimum tax credit carryforwards of approximately $23, which are
available to reduce future federal regular income taxes, if any, over an
indefinite period.

     At December 31, 2001, our share of the cumulative undistributed earnings of
foreign subsidiaries was approximately $7. No provision has been made for U.S.
or additional foreign taxes on the undistributed earnings of foreign
subsidiaries since we intend to continue to reinvest indefinitely these
earnings. Foreign tax credits would be available to substantially reduce or
eliminate any amount of additional U.S. tax that might be payable on these
foreign earnings in the event of distributions or sale.

Accrued Liabilities

   Included in accrued liabilities are the following items:

Contributing Employee Ownership Plan

     The Contributing Employee Ownership Plan is a defined contribution plan
available to essentially all domestic employees, which provides a match of
employee contributions. We are matching employee contributions with common
stock. Expenses related to the plan are based on common stock allocated to
participants. These costs (primarily our contributions) amounted to $6 in 2001
and $5 in 2000 and 1999.

     Employees become vested in the value of the contributions we make to the
CEOP according to a schedule based on service. After two years of service,
participants are 25% vested. They vest in increments of 25% for each additional
year and after five years of service, they are 100% vested in the value of the
contributions that we have made to their accounts.

     Employees may transfer any or all of the value of the investments purchased
with their own contributions, including Olin Common Stock, to any one or
combination of investments available in the Plan. Such transfers may be made
without limitation, at any time and as often as employees choose. The Olin
common stock purchased with our contributions may not be transferred until
employees terminate employment with the company. However, employees who are age
50 or older may withdraw any or all of the value of the Olin common stock
purchased with our contributions without the usual suspension of contribution
penalty. Provided the amount of the withdrawal is rolled over to an Individual
Retirement Account, tax payments would be deferred until the employee takes a
distribution from the Individual Retirement Account.

Stock Options

     Under the stock option plans, options may be granted to purchase shares of
our 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. Options
granted under the 1996 Stock Option Plan and the 2000 and the 1991 Long Term
Incentive Plans vest over three years. In 2001, long term

                                       48

<PAGE>

incentive awards were given with stock options representing one-half of the
aggregate value of the long term incentive award opportunity, and performance
share awards making up the other half. The option price was set at the fair
market value of common stock on the date of the grant, and the options have a
ten-year term. The other half of the individual long term incentive award takes
the form of performance shares, with the number of performance shares based on
the competitive analysis and the price of our stock at the time of the grant. At
the end of a three-year performance cycle, participants receive a performance
share award denominated in shares of our stock, paid half in shares of our stock
and half in cash, based on Olin's average annual return on capital in relation
to the average annual return on capital among the S&P MidCap 400 companies. In
2000, a one-time grant of Performance Accelerated Vesting Stock Options was
granted with an exercise price of $18.97, which represented fair value. Options
for 924,000 shares were outstanding at December 31, 2001. These options have a
term of 120 months and vest in 119 months, and can vest early, but only if the
stock price increases to $28 per share or more for 10 days in any 30 calendar
day period.

     The 2000 Long Term Incentive Plan and the 1996 Stock Option Plan are the
only plans with stock options available for future grants. At December 31, 2001,
total shares of 2,296,533 were available for grant under all active stock-based
plans. Of this total, stock options of 1,902,375 shares and stock awards of
394,158 shares were available for future grants. As a result of the spin-off of
Arch Chemicals the outstanding Olin options as of February 8, 1999 were
converted into both an option to purchase Olin common stock and an option to
purchase Arch Chemicals common stock with an adjustment of the exercise price
designed to preserve the "intrinsic value" at the time of the spin-off. Olin
will be responsible for delivering shares of Olin common stock upon exercise,
and Arch Chemicals will be responsible for delivering shares of Arch Chemicals
stock upon exercise. The options maintain the original vesting schedule. The
following table has been restated to reflect the new option price of the Olin
options as a result of the transaction described above.

     At December 31, 2001, common shares reserved for issuance under the 1988
Stock Option Plan, the 1991 Long Term Incentive Plan, the 1996 Stock Option
Plan, the 2000 Long Term Incentive Plan, and Options Available Only for Arch
Employees were 8,047,486. An additional 688,640 shares were reserved under the
Monarch Brass & Copper Corp. ("Monarch") Deferral Plan, 1997 Stock Plan for
Non-Employee Directors and the Employee Deferral Plan, and of these shares,
approximately 117,000 shares were committed.

     In 1996, we adopted SFAS No. 123, "Accounting for Stock-Based Compensation"
and as permitted by SFAS No. 123, we continue to account for the costs of stock
compensation in accordance with APB No. 25. Pro forma net income (loss) and
earnings (loss) per share were calculated based on the following assumptions as
if we had recorded compensation expense for the stock options granted during the
year. The fair value of each option granted during 2001, 2000 and 1999 was
estimated on the date of grant, using the Black-Scholes option-pricing model
with the following weighted-average assumptions used: dividend yield of 5.69% in
2001, 4.21% in 2000 and 5.35% in 1999, risk-free interest rate of 4.92% in 2001,
5.18% in 2000 and 6.25% in 1999, expected volatility of 29% in 2001, 2000 and
1999 and an expected life of 7 years. The fair value of options granted during
2001, 2000 and 1999 was $5.34, $5.59 and $3.85, respectively. The following
table shows the difference between reported and pro forma net income (loss) and
earnings (loss) per share as if we had recorded compensation expense for the
stock options granted during the year.

Shareholder Rights Plan

     Effective February 1996, our Board of Directors adopted a new Shareholder
Rights Plan to replace the prior plan which had been adopted in 1986. This plan
is designed to prevent an acquirer from gaining control of us without offering a
fair price to all shareholders. Each right entitles a shareholder (other than
the acquirer) to buy one-five hundredth share of Series A Participating
Cumulative Preferred Stock at an exercise price of one hundred twenty dollars.
The rights are exercisable only if a person acquires more than 15% of our common
stock or if our Board of Directors so determines following the commencement of a
tender or exchange offer to acquire more than 15% of our common stock. If any
person acquires more than 15% of our common stock and in the event of a
subsequent merger or combination, each right will entitle the holder (other than
the acquirer) to purchase stock or other property of the acquirer having a value
of twice the exercise price. We can redeem the rights at $.005 per right for a
certain period of time. The rights will expire on February 27, 2006, unless
redeemed earlier by us.

Segment Information

     We define segment operating income as earnings before interest expense,
interest income, other income, restructuring charge and unusual items and income
taxes, and include the operating results of non-consolidated affiliates. Segment
operating results in 2001 exclude the restructuring charge and unusual items
($42 million, pretax).

   Transfers between geographic areas are priced generally at prevailing
market prices. Export sales from the United States to unaffiliated customers
were $61, $93, and $73 in 2001, 2000, and 1999, respectively.

Acquisitions

   In June 2001, we acquired the stock of Monarch for approximately $48.
Monarch was a privately held, specialty brass manufacturer headquartered in
Waterbury, CT with annual revenues of approximately $95 in 2000. It produces and
distributes an array of high performance copper alloys and other materials used
for applications in electronics, telecommunications, automotive and building
products. We financed the purchase through our credit lines. The purchase price
exceeded the fair value of the identifiable net assets acquired by $19. The
acquisition has been accounted for using the purchase method of accounting. The
operating results of Monarch, which have been included in the accompanying
financial statements since the date of acquisition, were not material.

     Supplemental cash flow information on the business acquired is as follows:

Restructurings and Unusual Items

   For the full year 2001, we recorded restructuring charges totaling $39
pretax and unusual items of $3 pretax for a total of $42 or $0.67 diluted EPS.

   In the third quarter, we recorded a pretax charge for restructuring and
unusual items of $29 (or $0.40 diluted EPS) primarily for costs associated with
a salaried workforce reduction through an early retirement incentive program.
Cost of Goods Sold and Other Income include $2 and $1, respectively, of unusual
items. Cost of Goods Sold included the write-off of inventory associated with
cancelled customer orders. Other Income included the write-off of an investment
in an E-commerce company. The third-quarter restructuring charge of $26 related
to the 190 employees retiring in connection with the retirement program and
represented primarily pension and postretirement benefit curtailment losses and
severance. As of December 31, 2001, 150 employees had retired and the remainder
will retire in the first quarter of 2002. The severance of $4 recorded in
Accrued Liabilities will be paid out of our operating cash flows over time.

     In the fourth quarter we recorded a restructuring pretax charge of $13
pretax, (or $0.27 diluted EPS), primarily for costs associated with idling our
Indianapolis brass mill, consolidating distribution operations of the recently
acquired Monarch with the A.J. Oster metals service center business, and
reducing staffing levels in Chlor Alkali Products. A significant portion of the
charge relating to the idling of the Indianapolis facility represented primarily
pension and postretirement curtailment losses and severance for 200 employees.
Another portion of the charge related to 38 Chlor Alkali employees who accepted
our offer of a voluntary special separation program whereby employees accept a
voluntary lay off and receive full separation benefits and also receive their
accrued pension benefits at the same time. The balance of the restructuring
charge relates to costs associated with the consolidation of certain Monarch
facilities in order to optimize distribution operations. The severance and
fringe benefits of $8 recorded in Accrued Liabilities will be paid out of our
operating cash flows over time.

     The following table summarizes the major components of the 2001 charges and
the remaining balances as of December 31, 2001:

Discontinued Operations

     On February 8, 1999, we completed the spin-off of our specialty chemicals
businesses as Arch Chemicals, Inc. Under the terms of the spin-off of Arch
Chemicals, we distributed to our holders of common stock as of the close of
business on February 1, 1999 one Arch Chemicals common share for every two
shares of Olin common stock. In February 1999 prior to the distribution, we
borrowed $75 under a credit facility, which liability was assumed by Arch
Chemicals.

     The historical operating results of these businesses are shown net of tax
as discontinued operations in the consolidated statements of income.
Accordingly, 1999 includes the operating results of Arch Chemicals for the month
of January. The discontinued operations include an allocation of corporate
overhead with the allocation based on either effort committed or number of
employees. Management believes that the allocation methods used to allocate the
costs and expenses are reasonable; however, such allocated amounts may or may
not necessarily be indicative of what those expenses would have been had Arch
Chemicals operated independently of Olin. Interest expense was not allocated to
Arch Chemicals.

     We have entered into tax sharing agreements with Arch Chemicals effectively
providing that we will be responsible for the tax liability of Arch Chemicals
for the years that Arch Chemicals was included in our consolidated income tax
returns. Income taxes have been allocated to Arch Chemicals based on its pretax
income and calculated on a separate company basis pursuant to the requirements
of SFAS No. 109, "Accounting for Income Taxes". Income taxes allocated to the
discontinued operations were $2 in 1999.

     In addition, we entered into several other agreements with Arch Chemicals,
which cover such matters as technology transfers, transition services, covenants
not to compete and chlorine and caustic supply.

     Condensed historical combined income statement data of the discontinued
operations are summarized below:

                                                             1999

Environmental

     We are party to various governmental and private environmental actions
associated with waste disposal sites and manufacturing facilities. Charges to
income for investigatory and remedial efforts were $14 in 2001, $15 in 2000 and
$17 in 1999. The consolidated balance sheets include reserves for future
environmental expenditures to investigate and remediate known sites amounting to
$100 at December 31, 2001, and $110 at December 31, 2000, of which $73 and $85
are classified as other noncurrent liabilities, respectively.

         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 our 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
us, which could have a material adverse effect on our operating results and
financial condition. At December 31, 2001, we estimate we may have additional
contingent environmental liabilities of $40 in addition to the amounts for which
we have already taken a reserve.

Commitments and Contingencies

     We lease certain properties, such as railroad cars, distribution,
warehousing and office space, data processing and office equipment. 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 $32 in 2001, $33 in 2000 and $32 in 1999, (sublease
income is not significant). Future minimum rent payments under operating leases
having initial or remaining non-cancelable lease terms in excess of one year at
December 31, 2001 are as follows: $21 in 2002; $20 in 2003; $18 in 2004; $16 in
2005; $15 in 2006; and $61 thereafter.

     On December 31, 1997, we entered into a long-term, sulfur dioxide supply
agreement with Alliance Specialty Chemicals, Inc. ("Alliance"), formerly known
as RFC SO2, Inc. Alliance has the obligation to deliver annually 36,000 tons of
sulfur dioxide. Alliance owns the sulfur dioxide plant, which is located at our
Charleston, TN facility and is operated by us. The price for the sulfur dioxide
is fixed over the life of the contract. In addition, we are obligated to make a
minimum monthly payment of approximately $.2 to an outside third party.
Commitments related to this agreement are approximately $2 per year for each
year of 2002 through 2006 and $12 thereafter.

     There are a variety of non-environmental legal proceedings pending or
threatened against us. Probable losses related to those matters have been
accrued in the accompanying financial statements. Any contingent amounts in
excess of amounts accrued are not expected to have a material adverse effect on
our results of operations, financial position or liquidity.

Economic Value Added Performance Measure (Unaudited)

     In 1995, we selected an innovative business management system known as
Economic Value Added, or EVA(R). Developed by Stern Stewart & Company, EVA is a
management tool that builds upon and refines traditional tools. It is designed
to help maximize long-term profitability, increase return on capital employed
and operate businesses more effectively. EVA is a method of measuring a
company's financial health by taking operating profit after taxes and
subtracting a charge for capital employed. The table below summarizes our EVA
calculation for the years ended December 31, 2001 and 2000:

                                                  2001            2000

Earnings Before Interest and Taxes

     Earnings (loss) before interest and taxes ("EBIT") are calculated as pretax
profits (loss) plus interest expense, less interest income. For EVA purposes,
material gains and losses on asset or business sales and restructurings are
excluded from EBIT but instead, the related cash flows are considered permanent
increases or decreases to the capital employed and are therefore part of the
capital charge forever.

Adjustments to EBIT

     Various adjustments are made to EBIT in order to determine operating profit
before taxes, make EVA a better management tool and drive appropriate decision
making and include the following:

     Goodwill is considered a permanent investment in capital employed.
  Accordingly, an adjustment is made to add goodwill amortization back to EBIT
  and average capital employed is adjusted such that the original amount of
  goodwill purchased is included in the asset base.

     LIFO (last-in first-out) based inventory is restated to a FIFO (first-in
  first-out) basis to appropriately reflect the actual current investment in
  inventory.

                                       56

<PAGE>

     Operating Leases are considered investments in capital and therefore an
  adjustment is made to EBIT to remove the implicit financing cost and average
  capital is increased by the net present value of the operating leases.

     Environmental remediation accruals are removed from EBIT and the after tax
  cash cost of legacy environmental remediation expenditures is added to the
  average capital base.

     Special Charges, such as Restructuring Charge and Unusual Items in 2001,
  are excluded from EBIT and the actual cash expenditures are accounted for as a
  permanent increase in average capital.

     Major Asset Sales are accounted for such that the pretax book gain or loss
  is excluded from EBIT and any after tax cash gain is a permanent reduction of
  average capital and any after tax cash loss is a permanent increase to average
  capital.

Strategic Investment

     The strategic investment relates to adjustment for strategic investments
with negative short-term EVA impacts.

Capital Charge

     The capital charge is the EVA based average capital employed multiplied by
the cost of capital. The cost of capital is our target weighted average cost of
debt and equity capital.

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

<PAGE>

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

provided, and may vote either in person or by proxy. 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

shareholder's duly authorized attorney-in-fact or authorized officer, director,
employee or agent signing such writing or causing such shareholder's signature
to be affixed to such writing by any reasonable means including, but not limited
to, by facsimile signature.

     The President, any Vice President or the Secretary of the Corporation may
approve procedures to enable a shareholder or a shareholder's duly authorized
attorney-in-fact to authorize another person or persons to act for such
shareholder as proxy by transmitting or authorizing the transmission of a
telegram, cablegram, internet transmission, telephone transmission or other
means of electronic transmission to the person who will be the holder of the
proxy or to a proxy solicitation firm, proxy support service organization or
like agent duly authorized by the person who will be the holder of the proxy to
receive such transmission, provided that any such transmission must either set
forth or be submitted with information from which the judges or inspectors of
election can determine that the transmission was authorized by the shareholder
or the shareholder's duly authorized attorney-in-fact. If it is determined that
such transmissions are valid, the judges or inspectors of election shall specify
the information upon which they relied. Any copy, facsimile telecommunication or
other reliable reproduction of the writing or transmission created pursuant to
this Section 6 may be substituted or used in lieu of the original writing or
transmission for any and all purposes for which the original writing or
transmission could be used, provided that such copy, facsimile telecommunication
or other reproduction shall be a complete reproduction of the entire original
writing or transmission.

     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

                                       -3-

<PAGE>

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.

     SECTION 9.  Business Proposed by a Shareholder. To be properly brought
                 ----------------------------------
before a meeting of shareholders, business must be (i) specified in the notice
of meeting (or any supplement thereto) given by or at the direction of the Board
of Directors, (ii) otherwise properly brought before the meeting by or at the
direction of the Board of Directors or (iii) in the case of an annual meeting of
shareholders or a special meeting called at the request of shareholders in
accordance with these By-laws, properly brought before the meeting by a
shareholder. In addition to any other applicable requirements, for business to
be properly brought before a meeting by a shareholder, the shareholder must have
given timely notice thereof in writing to the Secretary of the Corporation. To
be timely, a shareholder's notice must be given, either by personal delivery or
by United States registered or certified mail, postage prepaid, to the Secretary
of the Corporation in the case of an annual meeting, not later than 90 days
before the anniversary of the immediately preceding annual meeting and in the
case of a special meeting called at the request of shareholders, in accordance
with the procedures set forth in Section 10 of Article I of these By-laws. A
shareholder's notice to the Secretary shall set forth as to each matter the
shareholder proposes to bring before the meeting (i) a brief description of the
business desired to be brought before the meeting, including the complete text
of any resolutions to be presented at the meeting with respect to such business,
and the reasons for conducting such business at the meeting, (ii) the name and
address of record of the shareholder proposing such business, (iii) the class
and number of shares of the Corporation that are beneficially owned by the
shareholder and any other person on whose behalf the proposal is made, and (iv)
any material interest of the shareholder and any other person on whose behalf
the proposal is made, in such business. In the event that a shareholder attempts
to bring business before a meeting without complying with the foregoing
procedure, the chairman of the meeting may declare to the meeting that the
business was not properly brought before the meeting and, if he shall so
declare, such business shall not be transacted.

     SECTION 10. Special Meeting at Request of Shareholders.
                 -------------------------------------------
(a) Any holder or holders of record of a majority of the outstanding shares of
Common Stock requesting the Corporation to call a special meeting of
shareholders pursuant to Section 2 of Article Eighth of the Restated Articles of
Incorporation (collectively, the "Initiating Shareholder") shall give written
notice of such request to the Secretary of the Corporation at its principal
executive offices (the "Notice"). The Notice shall be sent in the manner and
contain all the information that would be required in a notice to the Secretary
given pursuant to Section 9 of this Article I.

                                       -4-

<PAGE>

(b)  If the Initiating Shareholder owns of record a majority of the outstanding
Common Stock as determined by the Secretary of the Corporation, the Corporation
shall be required to call the special meeting of shareholders requested by the
Initiating Shareholder.

(c)  The record date for determining the shareholders of record entitled to vote
at a special meeting called pursuant to this Section 10 shall be fixed by the
Board of Directors which record date will be within 60 days of the date the
Secretary of the Corporation determines the Corporation is required to call such
special meeting. Written notice of the meeting shall be mailed by the
Corporation to shareholders of record on such record date within 10 days after
the record date (or such longer period as may be necessary for the Corporation
to file its proxy materials with, and receive and respond to the comments of,
the Securities and Exchange Commission), and the meeting will be held within 50
days after the date of mailing of the notice, as determined by the Board of
Directors.

(d)  The business to be conducted at a special meeting called pursuant to this
Section 10 shall be limited to the business set forth in the Notice and such
other business or proposals as the Board of Directors shall determine and shall
be set forth in the notice of meeting. The Board of Directors or the Chairman of
the Board of Directors may determine other rules and procedures for the conduct
of the meeting.

                                   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 eight 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 Bylaws. 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

                                       -5-

<PAGE>

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 election as directors
at a meeting only if it is an annual meeting and written notice of such
shareholder's intent to make such nomination or nominations has been given,
either by personal delivery or by United States registered or certified mail,
postage prepaid, to the Secretary of the Corporation not later than 90 days
before the anniversary of the immediately preceding annual meeting. Each such
notice shall set forth: (a) the name and address of the shareholder who intends
to make the nomination and of the person or persons to be nominated; (b) a
representation that the shareholder is a holder of record of shares of the
Corporation entitled to vote at such meeting (stating the class and number
thereof) and intends to appear in person or by proxy at the meeting to nominate
the person or persons specified in the notice; (c) a description of all
arrangements or understandings between the shareholder and each nominee and any
other person or persons (naming such person or persons) pursuant to which the
nomination or nominations are to be made by the shareholder; and (d) such other
information regarding each nominee proposed by such shareholder as would be
required to be included in a proxy statement filed pursuant to the proxy rules
of the Securities and Exchange Commission had the nominee been nominated or
intended to be nominated by the Board of Directors, and shall include a consent
signed by each such nominee to serve as a director of the Corporation if so
elected. The chairman of the meeting may refuse to acknowledge the nomination by
a shareholder of any person that is not made in compliance with the foregoing
procedure.

     SECTION 2. Compensation. Each director, in consideration of his serving as
                ------------
such, shall be entitled to receive from the Corporation such amount per annum or
such fees for attendance at Board and Committee meetings, or both, in cash or
other property, including securities of the Corporation, as the Board shall from
time to time determine, together with reimbursements for the reasonable expenses
incurred by him in connection with the performance of his duties. Nothing
contained herein shall preclude any director from serving the Corporation, or
any subsidiary or affiliated corporation, in any other capacity and receiving
proper compensation therefor. If the Board adopts a resolution to that effect,
any director may elect to defer all or any part of the annual and other fees
hereinabove referred to for such period and on such terms and conditions as
shall be permitted by such resolution.

     SECTION 3. Place of Meetings. The Board may hold its meetings at such place
                -----------------
or places within or without the Commonwealth of Virginia as it may from time to
time by resolution determine or as shall be specified or fixed in the respective
notices or waivers of notice thereof.

     SECTION 4. Organization Meeting. After each annual election of directors,
                --------------------
as soon as conveniently may be, the newly constituted Board shall meet for the
purposes of organization. At such organization meeting, the newly constituted
Board shall elect officers of the Corporation and transact such other business
as shall come before the meeting. Notice of organization meetings of the Board
need not be given. Any organization meeting may be held at any other time or
place which shall be specified in a notice given

                                       -6-

<PAGE>

as hereinafter provided for special meetings of the Board, or in a waiver of
notice thereof signed by all the directors.

     SECTION 5.  Regular Meetings. Regular meetings of the Board may be held at
                 ----------------
such time and place as may from time to time be specified in a resolution
adopted by the Board then in effect; and, unless otherwise required by such
resolution, or by law, notice of any such regular meeting need not be given.

     SECTION 6.  Special Meetings. Special meetings of the Board shall be held
                 ----------------
whenever called by the Chief Executive Officer, or by the Secretary at the
request of any three directors. Notice of a special meeting shall be mailed to
each director, addressed to him at his residence or usual place of business, not
later than the second day before the day on which such meeting is to be held, or
shall be sent addressed to him at such place by telegraph, cable or wireless, or
be delivered personally or by telephone, not later than the day before the day
on which such meeting is to be held. Neither the business to be transacted at,
nor the purpose of, any regular or special meeting of the Board need be
specified in the notice of such meeting, unless required by the Articles.

     SECTION 7.  Quorum. At each meeting of the Board the presence of a majority
                 ------
of the number of directors fixed by these By-laws shall be necessary to
constitute a quorum. The 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, except as may
be otherwise provided by law or by these By-laws. Any meeting of the Board may
be adjourned by a majority vote of the directors present at such meeting. Notice
of any adjourned meeting need not be given.

     SECTION 8.  Waivers of Notice of Meetings. Anything in these By-laws or in
                 -----------------------------
any resolution adopted by the Board to the contrary notwithstanding, notice of
any meeting of the Board need not be given to any director if such notice shall
be waived in writing signed by such director before, at or after the meeting, or
if such director shall be present at the meeting. Any meeting of the Board shall
be a legal meeting without any notice having been given or regardless of the
giving of any notice or the adoption of any resolution in reference thereto, if
every member of the Board shall be present thereat. Except as otherwise provided
by law or these By-laws, waivers of notice of any meeting of the Board need not
contain any statement of the purpose of the meeting.

     SECTION 9.  Telephone Meetings. Members of the Board or any committee may
                 ------------------
participate in a meeting of the Board or such committee by means of a conference
telephone or other means of communications whereby all directors participating
may simultaneously hear each other during the meeting, and participation by such
means shall constitute presence in person at such meeting.

     SECTION 10. Actions Without Meetings. Any action that may be taken at a
                 ------------------------
meeting of the Board or of a committee may be taken without a meeting if a
consent in writing, setting forth the action, shall be signed, either before or
after such action, by all of the directors or all of the members of the
committee, as the case may be. Such consent shall have the same force and effect
as a unanimous vote.

                                 ARTICLE III./1/
                     INDEMNIFICATION AND LIMIT ON LIABILITY.

     (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, unless such person engaged in willful misconduct or a knowing
violation of the criminal law.

     As used in this Article III: (i) the terms "liability" and "expense" shall
include, but shall not 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 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
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 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 of 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 to 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 contraction or as a matter of law.

     (f) In any proceeding brought by or in the right of the Corporation or
brought by or on behalf of shareholders of the Corporation, no director or
officer of the Corporation shall be liable to the Corporation or its
shareholders for monetary damages with respect to any transaction, occurrence or
course of conduct, whether prior or subsequent to the effective date of this
Article lll, except for liability resulting from such person's having engaged in
willful misconduct or a knowing violation of the criminal law or any federal or
state securities law.

     (g) An amendment to this Article III shall be approved only by a majority
of the votes entitled to be cast by each voting group entitled to vote thereon.

     SECTION 1. Executive Committee. The Board may, by resolution or resolutions
                -------------------
adopted by a majority of the number of directors fixed by these By-laws, appoint

the Corporation may be removed at any time, either with or without cause, by the
Board in its absolute discretion. Any such removal shall be without prejudice to
the recovery of damages for breach of the contract rights, if any, of the
officer, assistant officer or agent removed. Election or appointment of an

                ------------
Corporation may resign as such at any time by giving written notice of his
resignation to the Board, the Chief Executive Officer or the Secretary of the

shareholders at which the term of the class to which he has been elected
expires, and, in each case, until his successor shall be elected, or until his

instrument in writing in the name and on behalf of the Corporation, and (ii) may

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-delegation, and
shall be subject to such limitations and restrictions as may be imposed in the
written instrument of delegation by the person making such delegation.

     SECTION 2. Loans. No loans shall be contracted on behalf of the Corporation
                ------

Board. When authorized by the Board, any officer, employee or agent of the
Corporation may effect loans and advances at any time for the Corporation from
any bank, trust company or other institution, or from any firm, corporation or
individual, and for such loans and advances may make, execute and deliver
promissory notes, bonds or other certificates or evidences of indebtedness of
the Corporation and when so authorized may pledge, hypothecate or transfer any
securities or other property of the Corporation as security for any such loans
or advances. Such authority may be general or confined to specific instances.

Corporation to whom such power may from time to time be delegated by the Board.

     SECTION 5. Voting of Securities. Unless otherwise provided by the Board,
                ---------------------
the Chief Executive Officer may from time to time appoint an attorney or
attorneys, or agent or agents of the 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 may instruct the person or persons so appointed
as to the manner of casting such votes or giving such consent, and may execute
or cause to be executed in the name and on behalf of the Corporation and under
its corporate seal, or otherwise, all such written proxies or other instruments
as such officer may deem necessary or proper in the premises.

                                  ARTICLE VIII.

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

the case of loss, destruction or mutilation of certificates, no transfer of
stock shall be entered until the previous certificate, if any, given

                                      -14-

<PAGE>

for the same shall have been surrendered and canceled. 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.

what times and places, and under what conditions and regulations the accounts
and books and papers of the Corporation, or any of them, shall be open for the
inspection of the shareholders, and no shareholder shall have any right to
inspect any account or book or paper of the Corporation except as expressly
conferred by statute or by these By-laws or authorized by the Board.

made immediately after the close of the fiscal year and be ready for
presentation at the annual meeting of shareholders of the Corporation, and such
other examinations shall be made as the Board may direct.

otherwise require), or by the holders of the outstanding shares of the
Corporation entitled to vote generally at any annual or special meeting of the
shareholders when notice thereof shall have been given in the notice of the
meeting of shareholders.

                               EMERGENCY BY-LAWS.

                                      -16-

<PAGE>

     (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.

     (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

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

                                      -17-

<PAGE>

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.

                           9.125% Senior Note due 2011

     This Note is one of a duly authorized issue of debentures, notes, bonds or
other evidences of indebtedness of the Company (the "Debt Securities") of the
series hereinafter specified, all issued or to be issued under and pursuant to
an indenture dated as of June 15, 1992 (the "Original Indenture"), as amended
and supplemented by the First Supplemental Indenture dated as of March 18, 1994,
and as amended and supplemented by the Second Supplemental Indenture dated as of
December 11, 2001 (the Original Indenture, as amended by the First Supplemental
Indenture and the Second Supplemental Indenture is herein called the
"Indenture"), duly executed and delivered by the Company to JPMorgan Chase Bank
(f/k/a Chemical Bank), as trustee (the "Trustee"), to which Indenture and all
indentures supplemental thereto reference is hereby made for a description of
the rights, limitations of rights, obligations, duties and immunities thereunder
of the Trustee, the Company and the holders of the Debt Securities. Capitalized
terms used herein and not defined herein have the meanings ascribed thereto in
the Indenture. The Debt Securities may be issued in one or more series, which
different series may be issued in various aggregate principal amounts, may
mature at different times, may bear interest (if any) at different rates, may be
subject to different redemption provisions (if any), may be subject to different
sinking, purchase or analogous funds (if any), may be subject to different
covenants and Events of Default and may otherwise vary as in the Indenture
provided. This Note is one of a series of Debt Securities designated as the
9.125% Senior Notes due 2011 of the Company (the "Notes"), initially in an
aggregate principal amount of $200,000,000 on the Issue Date. Terms used herein
which are defined in the Indenture shall have the respective meanings assigned
thereto in the Indenture.

     In case an Event of Default with respect to the Notes shall have occurred
and be continuing, the principal hereof may be declared, and upon such
declaration shall become, due and payable, in the manner, with the effect and
subject to the conditions provided in the Indenture.

     The Indenture contains provisions permitting the Company and the Trustee,
with the consent of the Holders of not less than 66-2/3% in aggregate principal
amount of the Debt Securities at the time Outstanding of all series to be
affected (voting as one class), evidenced as in the Indenture provided, to
execute supplemental indentures adding any provisions to or changing in any
manner or eliminating any of the provisions of the Indenture or of any
supplemental indenture or modifying in any manner the rights of the Holders of
the Debt Securities of each such series; provided, however, that no such
supplemental indenture shall (i) extend the fixed maturity of any Debt
Securities, or reduce the principal amount thereof or any premium thereon or the
amount of any Sinking Fund Payment, or reduce the rate or extend the time of
payment of interest thereon, or reduce any premium payable upon redemption
thereof, without the consent of

<PAGE>

the Holder of each Debt Security so affected, or (ii) reduce the aforesaid
percentage of Debt Securities the consent of the Holders of which is required
for any such supplemental indenture, without the consent of the Holders of each
Debt Security so affected. It is also provided in the Indenture that, with
respect to certain defaults or Events of Default regarding the Debt Securities
of any series, prior to any declaration accelerating the maturity of such Debt
Securities, the Holders of a majority in aggregate principal amount Outstanding
of the Debt Securities of such series (or, in the case of certain defaults or
Events of Default, all the Debt Securities) may on behalf of the Holders of all
the Debt Securities of such series (or all of the Debt Securities, as the case
may be) waive any such past default or Event of Default and its consequences.
The preceding sentence shall not, however, apply to a default in the payment of
the principal of, premium, if any, or interest, if any, on any of the Debt
Securities. Any such consent or waiver by the Holder of this Note (unless
revoked as provided in the Indenture) shall be conclusive and binding upon such
Holder and upon all future Holders and owners of this Note and any Notes which
may be issued in exchange or substitution herefor, irrespective of whether or
not any notation thereof is made upon this Note or such other Notes.

     No reference herein to the Indenture and no provision of this Note or of
the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of and any premium and interest
on this Note at the place, at the respective times, at the rate and in the coin
or currency herein prescribed.

     The Notes are issuable in registered form without coupons in denominations
of $1,000 and any integral multiple of $1,000. At the office or agency of the
Company in the Borough of Manhattan, The City of New York, and in the manner and
subject to the limitations provided in the Indenture, but without the payment of
any service charge, Notes may be exchanged for a like aggregate principal amount
of Notes of other authorized denominations.

     The Notes will be redeemable as a whole at any time or in part from time to
time, at the option of the Company, on at least 30 but not more than 60 days
prior notice (a "Redemption Date"), at a redemption price equal to the greater
of (i) 100% of the principal amount of this Note and (ii) the present value of
the Remaining Scheduled Payments on the Notes being redeemed on the Redemption
Date, discounted to the Redemption Date on a semiannual basis (assuming a
360-day year consisting of twelve 30-day months) at the Treasury Rate (as
defined herein) plus 50 basis points, plus, in each case, accrued interest on
this Note to the Redemption Date (the "Redemption Price").

     "Comparable Treasury Issue" means the United States Treasury security
selected by an Independent Investment Banker as having a maturity comparable to
the remaining term of this Note to be redeemed that would be utilized, at the
time of selection and in accordance with customary financial practice, in
pricing new issues of corporate debt securities of comparable maturity to the
remaining term of this Note.

<PAGE>

"Independent Investment Banker" means Banc of America Securities LLC and/or
Salomon Smith Barney Inc.

     "Comparable Treasury Price" means, with respect to any Redemption Date, (i)
the average of Reference Treasury Dealer Quotations for such Redemption Date,
after excluding the highest and lowest such Reference Treasury Dealer
Quotations, or (ii) if the Trustee obtains fewer than three such Reference
Treasury Dealer Quotations, the average of all such quotations.

     "Reference Treasury Dealer" means Banc of America Securities LLC and
Salomon Smith Barney Inc. and, at the Company's option, other primary U.S.
Government Securities dealers in New York City selected by the Company.

     "Reference Treasury Dealer Quotations" means, with respect to each
Reference Treasury Dealer and any Redemption Date, the average, as determined by
the Trustee, of the bid and asked prices for the Comparable Treasury Issue
(expressed in each case as a percentage of its principal amount) quoted in
writing to the Trustee by such Reference Treasury Dealer at 5:00 p.m., New York
City time, on the third Business Day preceding such Redemption Date.

     "Remaining Scheduled Payments" means, with respect to this Note, the
remaining scheduled payments of the principal and interest thereon that would be
due after the related Redemption Date but for such redemption; provided,
however, that, if such Redemption Date is not an Interest Payment Date with
respect to this Note, the amount of the next succeeding scheduled interest
payment thereon will be reduced by the amount of interest accrued thereon to
such Redemption Date.

     "Treasury Rate" means, with respect to any Redemption Date, the rate per
year equal to the semi-annual equivalent yield to maturity of the Comparable
Treasury Issue, assuming a price for the Comparable Treasury Issue (expresses as
a percentage of its principal amount) equal to the Comparable Treasury Price for
such Redemption Date.

     Unless the Company defaults in payment of the Redemption Price, on and
after the Redemption Date interest will cease to accrue on the Notes or portions
thereof called for redemption and those Notes will cease to be outstanding.

     Upon due presentment for registration of transfer of this Note at the
office or agency of the Company in the Borough of Manhattan, The City of New
York, a new Note or Notes of authorized denominations for an equal aggregate
principal amount will be issued to the transferee in exchange therefor, subject
to the limitations provided in the Indenture, without charge except for any tax
or other governmental charge imposed in connection therewith.

<PAGE>

     The Company, the Trustee, any paying agent and any Debt Security registrar
may deem and treat the registered Holder hereof as the absolute owner of this
Note (whether or not this Note shall be overdue and notwithstanding any notation
of ownership or other writing hereon), for the purpose of receiving payment
hereof, or on account hereof, and for all other purposes, and neither the
Company nor the Trustee nor any paying agent nor any Debt Security registrar
shall be affected by any notice to the contrary. All payments made to or upon
the order of such registered Holder shall, to the extent of the sum of sums
paid, effectually satisfy and discharge liability for moneys payable on this
Note.

     No recourse for the payment of the principal of, or premium, if any, or
interest on this Note, or for any claim based hereon or otherwise in respect
thereof, and no recourse under or upon any obligation, covenant or agreement of
the Company in the Indenture or any indenture supplemental thereto or in any
Note, or because of the creation of any indebtedness represented thereby, shall
be had against any incorporator, stockholder, officer or director, as such,
past, present or future, of the Company or of any successor corporation, either
directly or through the Company or any successor corporation, whether by virtue
of any constitution, statute or rule of law or by the enforcement of any
assessment or penalty or otherwise, all such liability being, by the acceptance
hereof and as part of the consideration for the issue hereof, expressly waived
and released.

     This Debt Security shall be deemed to be a New York contract, and for all
purposes shall be construed in accordance with the laws of said State.

                                 DESCRIPTION OF
                           RESTRICTED STOCK UNIT AWARD
                                GRANTED UNDER THE
                       OLIN 2000 LONG TERM INCENTIVE PLAN

1.   Terms

     The terms and conditions of these Restricted Stock Units are contained in
     the Award Certificate evidencing the grant of such Award, this Award
     Description and in the Olin 2000 Long Term Incentive Plan (the "Plan").

2.   Definitions

     "Vesting Date" means with respect to a Restricted Stock Unit, the date on
     which you become entitled to receive the shares underlying the Restricted
     Stock Unit, as set forth in your Award Certificate.

     Other capitalized terms used but not defined herein have the meanings
     specified in the Plan.

3.   Vesting and Payment

     (a)  Except as otherwise provided in the Plan or in this Award Description,
          your interest in the Restricted Stock Units awarded to you will vest
          only at the close of business on the Vesting Date for such Restricted
          Stock Units, if you are employed by Olin from the grant date through
          the Vesting Date. Each Restricted Stock Unit not vested shall be
          forfeited.

     (b)  Each vested Restricted Stock Unit shall be payable by delivery of one
          share of Olin Common Stock (subject to adjustment as provided in the
          Plan), except as otherwise provided in the Plan.

     (c)  Each outstanding Restricted Stock Unit shall accrue Dividend
          Equivalents (amounts equivalent to the cash dividends payable in
          cash), deferred in the form of cash. Such Dividend Equivalents shall
          be paid only when and if the Restricted Stock Unit on which such
          Dividend Equivalents were accrued vests. Dividend Equivalents will
          accrue interest at an annual rate equal to Olin's before tax cost of
          borrowing as determined from time to time by the Chief Financial
          Officer, the Treasurer or the Controller of the Company (or in the
          event there is no such borrowing, the Federal Reserve A1/P1 Composite
          rate for 90-day commercial paper plus 10 basis points, as determined
          by any such officer) or such other rate as determined from time to
          time by the Board or the Committee, compounded quarterly, from the
          date accrued to the earlier of the date paid or forfeiture. To the
          extent a Restricted Stock Unit does not vest or is otherwise
          forfeited, any accrued and unpaid Dividend Equivalents (and any
          interest on such Dividend Equivalents) shall be forfeited.

<PAGE>

     (d)  The total number of vested Restricted Stock Units (and Dividend
          Equivalents and related interest) at the end of a calendar year shall
          be paid on or before March 15 of the following year, except as
          otherwise specifically provided in the Plan.

     (e)  Restricted Stock Units shall carry no voting rights nor, except as
          specifically provided herein, be entitled to receive any dividends or
          other rights enjoyed by shareholders.

4.   Termination of Employment

     (a)  Any Restricted Stock Units not yet vested shall be forfeited if your
          employment terminates either for cause or without Olin's written
          consent. If your employment should terminate before the applicable
          Vesting Date without cause and with Olin's written consent or by
          virtue of your death or total disability or retirement under an Olin
          benefit plan, the Committee shall determine, in its sole discretion,
          which outstanding Restricted Stock Units not yet vested (including
          Dividend Equivalents and related interest), if any, shall not be
          forfeited provided that you are not a Section 16 officer or director
          of Olin when your employment terminates, the Chief Executive Officer
          of Olin shall be authorized to make such determination.

     (b)  With respect to any non-forfeited Restricted Stock Units (and Dividend
          Equivalents and related interest) of a terminated Participant relating
          to incomplete Vesting Period, you will receive shares in payment of
          such Restricted Stock Units (and related Dividend Equivalents and
          interest, if any) as soon as practicable, subject to the provisions of
          the Plan.

5.   Tax Withholding

     Olin will withhold from the payout of the Restricted Stock Units (and
     related Dividend Equivalents) the amount necessary to satisfy your federal,
     state and local withholding tax requirements.

6.   Miscellaneous

     By accepting the Award of Restricted Stock Units, you agree that such Award
     is special compensation, and that any amount paid will not affect

     (a)  The amount of any pension under any pension or retirement plan in
          which you participate as an employee of Olin,

     (b)  The amount of coverage under any group life insurance plan in which
          you participate as an employee of Olin, or

     (c)  The benefits under any other benefit plan or any kind heretofore or
          hereafter in effect, under which the availability or amount of
          benefits is related to compensation.

        prohibited by Section 6(f)(ii); (vi) determine whether, to what extent,
        and under what circumstances cash, Shares, other securities, other
        Awards, other property and other amounts payable with respect to an
        Award under the Plan shall be deferred either automatically or at the
        election of the Participant or of the Committee; (vii) interpret and
        administer the Plan and any instrument or agreement relating to, or
        Award made under, the Plan; (viii) establish, amend, suspend or waive

        appropriate for the administration of the Plan; and (ix) make any other

        determination and take any other action that it deems necessary or
        desirable for such administration.

(b)     Committee Discretion. All designations, determinations, interpretations
        --------------------
        and other decisions with respect to the Plan or any Award shall be
        within the sole discretion of the Committee and shall be final,
        conclusive and binding upon all Persons, including Olin, any Affiliate,
        any Participants, any holder or beneficiary of any Award, any
        shareholder and any employee of Olin or of any Affiliate. The
        Committee's powers include the adoption of modifications, amendments,
        procedures, subplans and the like as are necessary to comply with
        provisions of the laws of other countries in which Olin or an Affiliate
        may operate in order to assure the viability of Awards granted under the
        Plan and to enable Participants employed in such other countries to
        receive benefits under the Plan and such laws, provided that no such
        action results in repricing of Options prohibited by Section 6(f)(ii).

(c)     Board Authority. If the Committee does not exist, or for any other
        ----------------
        reason determined by the Board, the Board may take any action under the
        Plan that would otherwise be the responsibility of the Committee.

(d)     Delegation. Notwithstanding any provision of the Plan to the contrary,
        ----------
        except to the extent prohibited by applicable law or the applicable
        rules of a stock exchange, the Committee may delegate to one or more
        officers or managers of Olin or any Affiliate, or a committee of such
        officers or managers, the authority, subject to such terms and
        limitations as the Committee shall determine, to grant Awards to, or to
        cancel, modify, waive rights or conditions with respect to, alter,
        discontinue, suspend, or terminate Awards held by, Employees who are not
        officers or directors of Olin for purposes of Section 16 of the
        Securities Exchange Act of 1934, as amended, provided that no such
        action shall result in repricing of Options prohibited by Section
        6(f)(ii).

(e)     Prohibition on Option Repricing. Notwithstanding any other provision of
        -------------------------------
        the Plan, neither the Board nor the Committee may reprice, replace or
        regrant any Option granted under the Plan or any other plan of Olin, (i)
        through cancellation and replacement or regrant with lower priced
        options or (ii) by lowering the option exercise price of a previously
        granted award, without the prior approval of Olin's shareholders.

Section 4.  Shares Available for Awards.
            ---------------------------

(a)     Shares Available. Subject to adjustment as provided in Section 4(b) of
        ----------------
        the Plan:


          (i)  The aggregate number of Shares available for granting Awards
               under the Plan shall be 2,250,000. If an Award is denominated in
               or relates to a security of Olin convertible into its Common
               Stock, the number of shares of Common Stock into which such
               security shall be convertible (calculated as of the date of grant
               of the Award, subject to adjustment as provided in Section 4(b)
               hereof or under the terms of such security) shall be deemed
               denominated in Shares and counted against the aggregate number of
               Shares available for the granting of Awards under the Plan.

          (ii) For purposes of this Section 4(a) and of Section 4(c)(iv):

                                       4

<PAGE>

               (A)  If any Shares covered by an Award are not delivered to a
                    Participant or beneficiary because the Award is forfeited or
                    canceled, or if the Shares are not delivered because the
                    Award is settled in cash or used to satisfy the applicable
                    tax withholding obligation, such Shares shall not be deemed
                    to have been delivered for purposes of determining the
                    maximum number of Shares available for delivery under the
                    Plan; and

               (B)  If the exercise price of any Option granted under the Plan
                    is satisfied by tendering Shares (by either actual delivery
                    or by attestation), only the number of Shares issued net of
                    the Shares tendered shall be deemed delivered for purposes
                    of determining the maximum number of Shares available for
                    delivery under the Plan.

(b)     Adjustments. In the event of any change in the Shares by reason of stock
        -----------
        dividends, stock splits, recapitalization, mergers, consolidations,
        combinations or exchanges of shares, split-ups, split-offs, spin-offs,
        liquidations or other similar changes in capitalization, or any
        distributions to shareholders other than cash dividends, (i) the
        numbers, class and prices of Shares covered by outstanding Awards under
        the Plan (provided that no such adjustment shall result in repricing of
        Options prohibited by Section 6(f)(ii) of the Plan), (ii) the aggregate
        number and class of Shares available under the Plan, and (iii) the
        numbers and class of Shares that may be the subject of Awards pursuant
        to Section 4(c), shall be adjusted by the Committee, whose determination
        shall be conclusive.

        (i)    Without limiting the foregoing, in the event of any split-up,
               split-off, spin-off or other distribution to shareholders of
               shares representing a part of Olin's business, properties and
               assets, the Committee may modify an outstanding Award so that
               such Award shall thereafter relate to Shares of Olin and shares
               of capital stock of the corporation owning the business,
               properties and assets so split-up, split-off, spun-off or
               otherwise distributed to shareholders of Olin in the same ratio
               in which holders of the Shares became entitled to receive shares
               of capital stock of the corporation owning the business,
               properties and assets so split-up, split-off or spun-off or
               otherwise distributed, provided that no such action results in
               repricing of Options prohibited by Section 6(f)(ii).

        (ii)   With respect to Awards of Incentive Stock Options, no such
               adjustment shall be authorized to the extent that such authority
               would cause the Plan to violate Section 422 of the Code or any
               successor provision thereto, unless the holder of such Award of
               Incentive Stock Options agrees to convert such options to
               Non-qualified Stock Options.

        (iii)  Notwithstanding the foregoing, a Participant to whom Dividend
               Equivalents or dividend units have been awarded shall not be
               entitled to receive a special or extraordinary dividend or
               distribution unless the Committee shall have expressly authorized
               such receipt.

(c)     Additional Restrictions. Subject to adjustment as provided in Section
        -----------------------
        4(b), the following additional maximums are imposed under the Plan:

                                       5

<PAGE>

          (i)    The maximum number of Shares that may be issued for Options
                 intended to be Incentive Stock Options shall be 900,000 Shares.

          (ii)   The maximum number of Shares that may be covered by Awards
                 granted to any one individual shall be 300,000 Shares during
                 any calendar year.

          (iii)  No more than 100,000 Shares may be subject to Restricted Stock
                 Awards, Restricted Stock Unit Awards and Performance Share
                 Awards, and no more than 300,000 Shares may be subject to
                 Options and Stock Appreciation Rights, granted to any one
                 individual during any calendar-year period (regardless of when
                 such Shares are deliverable) for any Award intended to  be
                 "performance-based compensation" (as that term is used for
                 purposes of Code Section 162(m)).

          (iv)   No more than 450,000 Shares may be subject to Restricted Stock
                 Awards, Restricted Stock Unit Awards and Performance Share
                 Awards.

Section 5.  Eligibility.
            -----------

Any Employee, including any officer or employee-director, of Olin or an
Affiliate shall be eligible to be designated a Participant, subject to any
restrictions imposed by applicable law. An Award may be granted to an Employee
prior to the date the Employee first performs services for the Company or the
Affiliate, provided that such Awards shall not become vested prior to the date
the Employee first performs such services.

Section 6.  Awards.
            ------

(a)       Options. The Committee is authorized to grant Options to Participants
          -------
          with the following terms and conditions and with such additional terms
          and conditions, not inconsistent with the provisions of the Plan, as
          the Committee shall determine:

          (i)    Exercise Price. The per Share exercise price shall be
                 --------------
                 determined by the Committee; provided, however, that such
                 exercise price shall not be less than the Fair Market Value of
                 a Share on the date of the Option grant; provided that, if a
                 Non-qualified Option is granted in connection with the
                 recipient's hiring, promotion or similar event, the exercise
                 price may be not less than the Fair Market Value of the Shares
                 on the date on which the recipient is hired or promoted (or the
                 similar event occurs), if the Option grant occurs not more than
                 90 days after the date of such event.

          (ii)   Option Term. The term of each Option shall be fixed by the
                 -----------
                 Committee, provided that in no event shall the term of an
                 Option be more than a period of ten years from the date of its
                 grant.

          (iii)  Exercise. The Committee shall determine the time or times at
                 --------
                 which an Option may be exercised in whole or in part, and the
                 method or methods by which, and the form or forms in which
                 payment of the exercise price with respect thereto may be made.

          (iv)   Incentive Stock Options. The terms of any Incentive Stock
                 -----------------------
                 Option granted under the Plan shall comply in all respects with
                 the provisions of Section 422 of the Code, or any

                                       6

<PAGE>

                  successor provision thereto, and any regulations promulgated
                  thereunder. Without limiting the preceding sentence, the
                  aggregate Fair Market Value (determined at the time an option
                  is granted) of Shares with respect to which Incentive Stock
                  Options are exercisable for the first time by a Participant
                  during any calendar year (under the Plan and any other plan of
                  the Participant's employer corporation and its parent and
                  subsidiary corporations providing for Options) shall not
                  exceed such dollar limitation as shall be applicable to
                  Incentive Stock Options under Section 422 of the Code or a
                  successor provision.

          (v)     Termination of Employment. In the event the employment of a
                  -------------------------
                  Participant to whom an Option has been granted under the Plan
                  shall be terminated (other than by reason of the Participant's
                  death or disability), such Option may, subject to the
                  provisions of the next to last sentence of Section 6(a)(vi) be
                  exercised (to the extent of the number of shares that the
                  Participant was entitled to purchase under such Option at the
                  termination of employment) at any time within three months
                  after such termination (which three-month period may be
                  extended by the Committee), but in no event shall such
                  three-month period or any such extension permit the exercise
                  of an Option after the expiration date of the Option. Options
                  granted under the Plan shall not be affected by any change of
                  duties or position so long as the Participant continues to be
                  an Employee.

          (vi)    Agreement to Service. Each Participant receiving an Option
                  --------------------
                  shall, by accepting the Option, agree that he or she will,
                  during employment, devote his or her entire time, energy and
                  skill to the service of Olin and the promotion of its
                  interests, subject to vacations, sick leave and other absences
                  in accordance with the regular policies of, or other reasons
                  satisfactory to, Olin and its Affiliates. Such employment
                  shall (subject to the terms of any contract between Olin or
                  any such Affiliate and such Participant) be at the pleasure of
                  Olin or such Affiliate, and shall be at such compensation as
                  Olin or such Affiliate shall determine from time to time. Upon
                  termination of such Participant's employment either (a) for
                  cause, or (b) voluntarily on the part of the Participant and
                  without the written consent of Olin, any Awards held by him or
                  her under the Plan, to the extent not theretofore exercised or
                  vested, shall forthwith terminate. Retirement pursuant to any
                  retirement plan of Olin or of an Affiliate shall be deemed to
                  be a termination of employment with Olin's consent.

          (vii)   Death. If a Participant to whom an Option has been granted
                  -----
                  shall die while an Employee, such Option may be exercised by
                  the Participant's executors, administrators, personal
                  representatives or distributees or permitted transferees at
                  any time within a period of one year after the Participant's
                  death (which period may be extended by the Committee),
                  regardless of whether or not such Option had vested at the
                  time of death. If a Participant to whom an Option has been
                  granted shall die after his or her employment has terminated
                  but while the Option remains exercisable, the Option may be
                  exercised by the persons described above at any time within
                  the longer of (a) the period that the Participant could have
                  exercised the Option had he or she not died, or (b) one year
                  after the date of death (which period may be extended by the
                  Committee), but only to the extent the Option was exercisable
                  at the time of the Participant's death.

                                       7

<PAGE>

          (viii)  Disability. If a Participant to whom an Option has been
                  ----------
                  granted shall become totally and permanently disabled, as that
                  term is defined in Section 22(e)(3) of the Code (or a
                  successor provision), and the Participant's employment is
                  terminated as a result, such option may be exercised by the
                  Participant or permitted transferee within one year after the
                  date of termination of employment, to the extent that the
                  Option was exercisable at the time of termination of
                  employment.

(b)       Stock Appreciation Rights. The Committee is authorized to grant Stock
          -------------------------
          Appreciation Rights to Participants which may but need not relate to a
          specific Option granted under the Plan. Subject to the terms of the
          Plan and any applicable Award Agreement, each Stock Appreciation Right
          granted under the Plan shall confer on the holder thereof a right to
          receive, upon exercise thereof, up to the excess of (i) the Fair
          Market Value of one Share on the date of exercise over (ii) the
          exercise price of the right as specified by the Committee, which shall
          not be less than the Fair Market Value of one Share on the date of
          grant of the Stock Appreciation Right. Subject to the terms of the
          Plan and any applicable Award Agreement, the exercise price, term,
          methods of exercise, methods of payment or settlement and any other
          terms and conditions of any Stock Appreciation Right shall be as
          determined by the Committee, but in no event shall the term of a Stock
          Appreciation Right exceed a period of ten years from the date of its
          grant.

(c)       Other Stock Awards.
          ------------------

          (i)     Issuance. The Committee is authorized to grant Awards of
                  --------
                  Restricted Stock, Restricted Stock Units and Performance
                  Shares to Participants.

          (ii)    Dividends and Dividend Equivalents. An Award (including
                  ----------------------------------
                  without limitation an Option or Stock Appreciation Right) may
                  provide the Participant with the right to receive dividend
                  payments or dividend equivalent payments with respect to
                  Shares subject to the Award (both before and after the Shares
                  subject to the Award are earned, vested, or acquired), which
                  payments may be either made currently or credited to an
                  account for the Participant, and may be settled in cash or
                  Shares as determined by the Committee. Any such settlements,
                  and any such crediting of dividends or dividend equivalents or
                  reinvestment in Shares, may be subject to such conditions,
                  restrictions and contingencies as the Committee shall
                  establish, including the reinvestment of such credited amounts
                  in Share equivalents.

          (iii)   Restrictions. Any such Award shall be subject to such
                  ------------
                  conditions, restrictions and contingencies as the Committee
                  may impose (including, without limitation, any limitation on
                  the right to vote Restricted Stock or the right to receive any
                  dividend or other right or property), which may lapse
                  separately or in combination at such time or times, as the
                  Committee may deem appropriate, provided that in order for a
                  Participant to vest in Awards of Restricted Stock, the
                  Participant must remain in the employ of Olin or an Affiliate
                  for a period of not less than one (1) year after the grant of
                  a performance-based Restricted Stock Award, and not less than
                  three (3) years after the grant of a Restricted Stock Award
                  that is not performance-based, in each case, subject to
                  Section 9 hereof and subject to relief for specified reasons
                  as may be approved by the Committee. Notwithstanding the
                  foregoing, the Committee may grant Awards for

                                      8

<PAGE>

                  Restricted Stock for an aggregate number of Shares not to
                  exceed 45,000 which vest in less than one (1) year after the
                  date of grant, including immediate vesting.

           (iv)   Forfeiture. Except as otherwise determined by the Committee,
                  ----------
                  upon termination of employment for any reason during the
                  applicable restriction period, all Shares of Restricted Stock
                  still subject to restriction shall be forfeited and reacquired
                  by Olin.

           (v)    Performance-Based Awards. The Committee may designate whether
                  ------------------------
                  any such Awards being granted to a Participant is intended to
                  be "performance-based compensation" as that term is used in
                  Section 162(m) of the Code. Any Award so designated shall be
                  conditioned on the achievement of one or more performance
                  measures. Performance measures that may be used by the
                  Committee for such purpose shall be based on one or more of
                  the following: Pre-Tax Profit and/or Earnings Per Share, Cash
                  Flow, Economic Value Added, ROE, Return on Capital or RONA.
                  For Awards intended to be "performance-based compensation,"
                  the grant of the Awards and the establishment of the
                  performance measures shall be made during the period required
                  under Code Section 162(m).

(d)      Forms of Payment Under Awards. Subject to the terms of the Plan and of
         -----------------------------
         any applicable Award agreement, payments to be made by Olin or an
         Affiliate upon the grant, exercise, or payment of an Award may be made
         in such form or forms as the Committee shall determine, including,
         without limitation, cash, Shares, other securities, other Awards, or
         other property or any combination thereof, and may be made in a single
         payment or transfer, in installments, or on a deferred basis, in each
         case in accordance with rules and procedures established by the
         Committee. Notwithstanding the foregoing, the payment of the exercise
         price of an Option shall be subject to the following:

         (i)      Subject to the following provisions of this subsection the
                  full exercise price for Shares purchased upon the exercise of
                  any Option shall be paid at the time of such exercise (except
                  that, in the case of an exercise arrangement approved by the
                  Committee and described below, payment may be made as soon as
                  practicable after the exercise).

         (ii)     The exercise price shall be payable in cash or by tendering,
                  by either actual delivery of Shares or by attestation, Shares
                  acceptable to the Committee, which Shares were either acquired
                  at least six months before the exercise date or purchased on
                  the open market, and valued at Fair Market Value as of the day
                  of exercise, or in any combination thereof, as determined by
                  the Committee.

         (iii)    The Committee may permit a Participant to elect to pay the
                  exercise price upon the exercise of an Option by irrevocably
                  authorizing a third party to sell Shares (or a sufficient
                  portion of the Shares) acquired upon exercise of an Option and
                  remit to Olin a sufficient portion of the sale proceeds to pay
                  the entire exercise price and any tax withholding resulting
                  from such exercise.

(e)      Limits on Transfer of Awards. No Award (other than Released Securities)
         ----------------------------
         or right thereunder shall be assignable or transferable by a
         Participant, other than:

                                       9

<PAGE>

         (i)      by will or the laws of descent and distribution (or, in the
                  case of an Award of Restricted Securities, to Olin); or

         (ii)     in the case of Awards other than Incentive Stock Options, to
                  the extent permitted under the terms of the Award, by a gift
                  or domestic relations order to any Family Member, to a trust
                  in which the Participant and/or his or her Family Members hold
                  more than 50% of the beneficial interest, to a foundation in
                  which the Participant and/or Family Members control the
                  management of assets, and any other entity in which the
                  Participant and/or his or her Family Members own more than 50%
                  of the voting interests.

         For purposes of this provision, a transfer to an entity in exchange for
         an interest in that entity shall constitute a gift.

(f)      General.
         -------

           (i)    No Cash Consideration for Awards. Participants shall not be
                  --------------------------------
                  required to make any cash payment for the granting of an Award
                  except for such minimum consideration as may be required by
                  applicable law.

           (ii)   Awards May Be Granted Separately or Together. Awards may be
                  --------------------------------------------
                  granted either alone or in addition to, in tandem with, or in
                  substitution for any other Award or any award or benefit
                  granted under any other plan or arrangement of Olin or any
                  Affiliate, or as payment for or to assure payment of an award
                  or benefit granted under any such other such plan or
                  arrangement, provided that the purchase or exercise price
                  under an Option or other Award encompassing the right to
                  purchase Shares shall not be reduced by the cancellation of
                  such Award and the substitution of another Award. Awards so
                  granted may be granted either at the same time as or at a
                  different time from the grant of such other Awards or awards
                  or benefits.

           (iii)  General Restrictions. Delivery of Shares or other amounts
                  --------------------
                  under the Plan shall be subject to the following:


                  (A)   Notwithstanding any other provision of the Plan, Olin
                        shall have no liability to deliver any Shares under the
                        Plan or make any other distribution of benefits under
                        the Plan unless such delivery or distribution would
                        comply with all applicable laws (including, without
                        limitation, the requirements of the Securities Act of
                        1933), and the applicable requirements of any securities
                        exchange or similar entity.

                  (B)   To the extent that the Plan provides for issuance of
                        stock certificates to reflect the issuance of Shares the
                        issuance may be effected on a non-certificated basis, to
                        the extent not prohibited by applicable law or the
                        applicable rules of any stock exchange.

           (iv)   Agreement With Olin. An Award under the Plan shall be subject
                  -------------------
                  to such terms and conditions, not inconsistent with the Plan,
                  as the Committee shall, in its sole discretion, prescribe. The
                  terms and conditions of any Award to any Participant may be
                  reflected

                                       10

<PAGE>

                  in such form of written document as is determined by the
                  Committee. A copy of such document shall be provided to the
                  Participant, and the Committee may, but need not, require the
                  Participant to sign a copy of such document, (an "Award
                  Agreement" regardless of whether any Participant signature is
                  required).

           (v)    Beneficiary. A Participant may, in the manner established by
                  -----------
                  the Committee, designate a beneficiary or beneficiaries with
                  respect to any Award to exercise the rights of the
                  Participant, and to receive any property distributable, upon
                  the death of the Participant. Each Award, and each right under
                  any Award, shall be exercisable, during the Participant's
                  lifetime, only by the Participant or a permitted transferee,
                  or, if permissible under applicable law by the Participant's
                  guardian or legal representative.

           (vi)   No Lien or Security Interest. No Award (other than Released
                  ----------------------------
                  Securities), and no right under any such Award, may be
                  pledged, attached or otherwise encumbered other than in favor
                  of Olin, and any purported pledge, attachment, or encumbrance
                  thereof other than in favor of Olin shall be void and
                  unenforceable against Olin or any Affiliate.

           (vii)  No Rights to Awards. No Employee, Participant or other Person
                  -------------------
                  shall have any claim to be granted an Award, and there is no
                  obligation for uniformity of treatment of Employees,
                  Participants or beneficiaries of Awards under the Plan. The
                  terms and conditions of Awards need not be the same with
                  respect to each recipient. The prospective recipient of any
                  Award under the Plan shall not, with respect to such Award, be
                  deemed to have become a Participant, or to have any rights
                  with respect to such Award, until and unless such recipient
                  shall have executed an agreement or other instrument accepting
                  the Award required by the Committee and delivered a fully
                  executed copy thereof to Olin, and otherwise complied with the
                  then applicable terms and conditions.

           (viii) Withholding. All distributions under the Plan are subject to
                  -----------
                  withholding of all applicable taxes, and, except as otherwise
                  provided by the Committee, the delivery of any Shares or other
                  benefits under the Plan to a Participant are conditioned on
                  satisfaction of the applicable withholding requirements. The
                  Committee, in its discretion, and subject to such requirements
                  as the Committee may impose prior to the occurrence of such
                  withholding, may permit such withholding obligations to be
                  satisfied through cash payment by the Participant, through the
                  surrender of Shares which the Participant already owns, or
                  through the surrender of Shares to which the Participant is
                  otherwise entitled under the Plan.

           (ix)   Other Compensation Arrangements. Nothing contained in the Plan
                  -------------------------------
                  shall prevent Olin or any Affiliate from adopting or
                  continuing in effect other or additional compensation
                  arrangements, and such arrangements may be either generally
                  applicable or applicable only in specific cases.

           (x)    No Right to Employment. The grant of an Award shall not be
                  ----------------------
                  construed as giving a Participant the right to be retained in
                  the employ of Olin or any Affiliate. Nothing in the Plan or
                  any Award Agreement shall limit the right of Olin or an
                  Affiliate at any time to dismiss a Participant from
                  employment, free from any liability or any claim under the
                  Plan or the Award Agreement.

           (xi)   Governing Law. The validity, construction and effect of the
                  -------------
                  Plan and any rules and regulations relating to the Plan shall
                  be determined in accordance with the laws of the State of
                  Connecticut, excluding any conflicts or choice of law rule or
                  principle that might otherwise refer construction or
                  interpretation of this Plan or any award Agreement to the
                  substantive law of another jurisdiction.

           (xii)  Severability. If any provision of the Plan or any Award is
                  ------------
                  determined to be invalid, illegal or unenforceable, or as to
                  any Person or Award, or would disqualify the Plan or any
                  Award, such provision shall be construed or deemed amended to
                  conform to applicable laws, or, if it cannot be so construed
                  or deemed amended without, in the determination of the
                  Committee, materially altering the intent of the Plan or the
                  Award, such provision shall be stricken as to such Person or
                  Award, and the remainder of the Plan and any such Award shall
                  remain in full force and effect.

           (xiii) No Trust or Fund Created. Neither the Plan nor any Award shall
                  ------------------------
                  create or be construed to create a trust or separate fund of
                  any kind or a fiduciary relationship between Olin or any
                  Affiliate and a Participant or any other Person. To the extent
                  that any Person acquires a right to receive payments from Olin
                  or any Affiliate pursuant to an Award, such right shall be no
                  greater than the right of any unsecured general creditor of
                  Olin or any Affiliate.


           (xiv)  No Fractional Shares. No fractional Shares shall be issued or
                  --------------------
                  delivered pursuant to the Plan or any Award, and the Committee
                  shall determine whether cash, other securities or other
                  property shall be paid or transferred in lieu of any
                  fractional Shares, or whether such fractional Shares or any
                  rights thereto shall be canceled, terminated or otherwise
                  eliminated.

           (xv)   Share Certificates. All certificates for Shares or other
                  ------------------
                  securities delivered under the Plan pursuant to any Award or
                  the exercise thereof shall be subject to such stop transfer
                  orders and other restrictions as the Committee may deem
                  advisable under the Plan or the rules, regulations and other
                  requirements of the Securities and Exchange Commission, any
                  stock exchange upon which such Shares or other securities are
                  then listed, and any applicable Federal or state securities
                  laws, and the Committee may cause a legend or legends to be
                  put on any such certificates to make appropriate reference to
                  such restrictions.

           (xvi)  Conflict with Plan. In the event of any inconsistency or
                  ------------------
                  conflict between the terms of the Plan and an Award Agreement,
                  the terms of the Plan shall govern.

Section 7.  Amendment and Termination.
            -------------------------

(a)  Amendments to the Plan. The Board or the Committee may amend, suspend,
     ----------------------
     discontinue or terminate the Plan, including, without limitation, any
     amendment, suspension, discontinuation or termination that would impair the
     rights of any Participant, or any other holder or beneficiary of any Award
     theretofore granted, without the consent of any shareholder, Participant,
     other holder or beneficiary of an Award, or other Person; provided,
     however, that, notwithstanding any other provision of the Plan or any Award
     Agreement, without the

                                       12

<PAGE>

         approval of the shareholders of Olin, no such amendment, suspension,
         discontinuation or termination shall be made that would:

           (i)    increase the total number of Shares available for Awards under
                  the Plan or the total number of Shares subject to one or more
                  categories of Awards pursuant to Section 4(c), in either case
                  except as provided in Section 4(b);

           (ii)   reduce the minimum Option exercise price, except as provided
                  in Section 4(b); or

           (iii)  permit repricing of Options prohibited by Section 6(f)(ii);
                  and

         provided further that no amendment, suspension, discontinuation or
         -------- -------
         termination (i) that would impair the rights of such Participant,
         holder or beneficiary shall be made with respect to Section 9 of the
         Plan after a Change in Control, as defined therein and (ii) may
         increase the amount of payment of any Award to any Participant.

(b)      Amendments to Awards. The Committee may waive any conditions or rights
         --------------------
         with respect to, or amend, alter, suspend, discontinue, or terminate,
         any unexercised Award theretofore granted, prospectively or
         retroactively, without the consent of any relevant Participant or
         holder or beneficiary of an Award, provided that no amendment,
         alteration, suspension, discontinuation or termination of an Award that
         would impair the rights of such Participant, holder or beneficiary
         shall be made after a Change in Control, as defined in Section 9;
         provided further that the Committee may not increase the payment of any
         Award granted any Participant.

(c)      Adjustments of Awards Upon Certain Acquisitions. In the event Olin or
         -----------------------------------------------
         any Affiliate shall assume outstanding employee awards or the right or
         obligation to make future such awards in connection with the
         acquisition of another business or another Person, the Committee may
         make such adjustments, not inconsistent with the terms of the Plan, in
         the terms of Awards as it shall deem appropriate.

(d)      Adjustments of Awards Upon the Occurrence of Certain Unusual or
         ---------------------------------------------------------------
         Nonrecurring Events. The Committee may make adjustments in the terms
         -------------------
         and conditions of Awards in recognition of unusual or nonrecurring
         events (including, without limitation, the events described in Section
         4(b) hereof) affecting Olin, any Affiliate, or the financial statements
         of Olin or any Affiliate, or of changes in applicable laws,
         regulations, or accounting principles, whenever the Committee
         determines that statements of Olin or any Affiliate, or of changes in
         applicable laws, regulations, or accounting principles, whenever the
         Committee determines that such adjustments are appropriate in order to
         prevent dilution or enlargement of the benefits to be made available
         under the Plan.

Section 8.  Additional Conditions to Enjoyment of Awards.
            --------------------------------------------

(a)      The Committee may cancel any unexpired, unpaid or deferred Awards if at
         any time the Participant is not in compliance with all applicable
         provisions of the Award Agreement, the Plan and the following
         conditions:

                                      13

<PAGE>

           (i)    A Participant shall not render services for any Person or
                  engage, directly or indirectly, in any business which, in the
                  judgment of the Committee is or becomes competitive with Olin
                  or any Affiliate, or which is or becomes otherwise prejudicial
                  to or in conflict with the interests of Olin or any Affiliate.
                  Such judgment shall be based on the Participant's positions
                  and responsibilities while employed by Olin or an Affiliate,
                  the Participant's post employment responsibilities and
                  position with the other Person or business, the extent of
                  past, current and potential competition or conflict between
                  Olin or an Affiliate and the other Person or business, the
                  effect on customers, suppliers and competitors of the
                  Participant's assuming the post employment position, the
                  guidelines established in the then current edition of Olin's
                  Standards of Ethical Business Practices, and such other
                  considerations as are deemed relevant given the applicable
                  facts and circumstances. The Participant shall be free,
                  however, to purchase as an investment or otherwise, stock or
                  other securities of such Person or business so long as they
                  are listed upon a recognized securities exchange or traded
                  over the counter, and such investment does not represent a
                  substantial investment to the Participant or a greater than 1%
                  equity interest in the organization or business.

           (ii)   Participant shall not, without prior written authorization
                  from Olin, disclose to anyone outside Olin, or use in other
                  than Olin's business, any secret or confidential information,
                  knowledge or data, relating to the business of Olin or an
                  Affiliate in violation of his or her agreement with Olin or
                  the Affiliate.

           (iii)  A Participant, pursuant to his or her agreement with Olin or
                  an Affiliate, shall disclose promptly and assign to Olin or
                  the Affiliate all right, title and interest in any invention
                  or idea, patentable or not, made or conceived by the
                  Participant during employment by Olin or the Affiliate,
                  relating in any manner to the actual or anticipated business,
                  research or development work of Olin or the Affiliate and
                  shall do anything reasonably necessary to enable Olin or the
                  Affiliate to secure a patent where appropriate in the United
                  States and in foreign countries.

(b)      Notwithstanding any other provision of the Plan, the Committee in its
         sole discretion may cancel any Award at any time prior to the exercise
         thereof, if the employment of the Participant shall be terminated,
         other than by reason of death, unless the conditions in this Section 8
         are met.

(c)      Failure to comply with the conditions of this Section 8 prior to, or
         during the six months after, any exercise, payment or delivery pursuant
         to an Award shall cause the exercise, payment or delivery to be
         rescinded. Olin shall notify the Participant in writing of any such
         rescission within two years after such exercise payment or delivery and
         within 10 days after receiving such notice, the Participant shall pay
         to Olin the amount of any gain realized or payment received as a result
         of the exercise, payment or delivery rescinded. Such payment shall be
         made either in cash or by returning to Olin the number of Shares that
         the Participant received in connection with the rescinded exercise,
         payment or delivery.

(d)      Upon exercise, payment or delivery pursuant to an Award, the Committee
         may require the Participant to acknowledge the terms and conditions of
         the Plan and to certify on a form acceptable to the Committee, that he
         or she is in compliance with the terms and conditions of the Plan.

(e)      Nothing herein shall be interpreted to limit the obligations of a
         Participant under his or her employee agreement or any other agreement
         with Olin.

Section 9.  Change in Control.
            -----------------

(a)      Except as the Board or the Committee may expressly provide otherwise
         prior to a Change in Control of Olin (as defined below) in the event of
         a Change in Control of Olin:

           (i)    all Options and Stock Appreciation Rights then outstanding
                  shall become immediately and fully exercisable,
                  notwithstanding any provision therein for the exercise in
                  installments;

           (ii)   all restrictions and conditions of all Restricted Stock and
                  Restricted Stock Units then outstanding shall be deemed
                  satisfied as of the date of the Change in Control; and

           (iii)  all Performance Share Awards shall become vested, deemed
                  earned in full and promptly paid to the Participants, cash
                  units in cash and phantom stock units in the Shares
                  represented thereby or such other securities, property or cash
                  as may be deliverable in respect of Shares as a result of a
                  Change in Control, without regard to payment schedules and
                  notwithstanding that the applicable performance cycle or
                  retention cycle shall not have been completed.

(b)      A Change in Control of Olin means:

           (i)    Olin ceases to be, directly or indirectly, owned by at least
                  1,000 stockholders;

           (ii)   A person, partnership, joint venture, corporation or other
                  entity, or two or more of any of the foregoing acting as a
                  "person" within the meaning of Section 13(d)(3) of the
                  Securities Exchange Act of 1934, as amended (the "Act"), other
                  than Olin, a majority-owned subsidiary of Olin or an employee
                  benefit plan (or the plan's related trust) of Olin or such
                  subsidiary, become(s) the "beneficial owner" (as defined in
                  Rule 13d-3 under such Act) of 20% or more of the then
                  outstanding voting stock of Olin;

           (iii)  During any period of two consecutive years, individuals who at
                  the beginning of such period constitute Olin's Board of
                  Directors (together with any new Director whose election by
                  Olin's Board of Directors or whose nomination for election by
                  Olin's stockholders was approved by a vote of at least
                  two-thirds of the Directors then still in office who either
                  were directors at the beginning of such period or whose
                  election or nomination for election was previously so
                  approved) cease for any reason to constitute a majority of the
                  directors then in office;

           (iv)   All or substantially all of the business of Olin is disposed
                  of pursuant to a merger, consolidation or other transaction in
                  which Olin is not the surviving corporation or Olin combines
                  with another company and is the surviving corporation (unless
                  the shareholders of Olin immediately following such merger,
                  consolidation, combination, or other transaction beneficially
                  own, directly or indirectly, more than 50% of the aggregate
                  voting stock or other ownership interests of (x) the entity or
                  entities, if any,

                                     15

                  that succeed to the business of Olin or (y) the combined
                  company) or

           (v)    Approval by Olin's shareholders of (i) a sale of all or
                  substantially all the assets of Olin or (ii) a liquidation or
                  dissolution of Olin.

(c)       In the event that a Participant participates or agrees to participate
          by loan or equity investment (other than through ownership of less
          than 1% of publicly traded securities of another company) in a
          transaction ("acquisition") which would result in an event described
          in Section 9(b)(i) or (ii), the Participant must promptly disclose
          such participation or agreement to Olin. If the Participant so
          participates or agrees to participate, no benefits or payments due
          under the Plan or by virtue of the Change in Control provisions
          contained in any compensation or benefit plan of Olin will be paid to
          the Participant until the acquiring group in which the Participant
          participates or agrees to participate has completed the acquisition.
          In the event the Participant so participates or agrees to participate
          and fails to disclose his participation or agreement, the Participant
          will not be entitled to any benefits or payments under the Plan or by
          virtue of Change in Control provisions in any Olin compensation or
          benefit plan, notwithstanding any of the terms hereof or thereof.

(d)       Anything in the Plan to the contrary notwithstanding, in the event
          that it shall be determined that any benefit, payment or distribution
          by Olin to or for the benefit of the Participant (whether paid or
          payable or distributed or distributable) pursuant to the terms of the
          Plan but determined without regard to any additional payments required
          under this Section 9(d), would be subject to the excise tax imposed by
          Section 4999 of the Internal Revenue Code of 1986, as amended, the
          Participant shall be entitled to receive an additional payment (the
          "Gross-Up Payment") in an amount equal to (i) the amount of the excise
          tax imposed on the Participant in respect of the benefits or payments
          received pursuant to the Plan (the "Excise Tax") plus (ii) all
          federal, state and local income, employment and excise taxes
          (including any interest or penalties imposed with respect to such
          taxes) imposed on the Participant in respect of the Gross-Up Payment,
          such that after payments of all such taxes (including any applicable
          interest or penalties) on the Gross-Up Payment, the Participant
          retains a portion of the Gross-Up Payment equal to the Excise Tax,
          provided that, if the Participant receives a Gross-Up Payment with
          respect to benefits or payments received under the Plan pursuant to
          another benefit or compensation plan or agreement, the Gross-Up
          Payment under this Section 9(d) shall be reduced by the amount of such
          other Gross-Up Payments paid in respect to the Excise Tax due as the
          result of the benefits or payments received under the Plan.

Section 10.  Effective Date and Term.
             -----------------------

Subject to the approval of Olin's shareholders at the 2000 annual shareholders
meeting the Plan shall be effective as of January 27, 2000 (the "Effective
Date"); provided, however, that to the extent that Awards are granted under the
Plan prior to its approval by shareholders, the Awards shall be contingent on
approval of the Plan by the shareholders of Olin at such annual meeting. The
Plan shall be unlimited in duration and, in the event of Plan termination, shall
remain in effect as long as any Awards under it are outstanding; provided;
however, that, to the extent required by the Code, no Incentive Stock Option may
be granted under the Plan on a date that is more than ten years from the date
the Plan is adopted.
