RECENT DEVELOPMENTS
 
  In April 1994, Olin acquired the medium caliber ammunition business of
GenCorp's Aerojet--General Corporation's Ordnance Division. The acquisition
expanded Olin's medium caliber ammunition family and positioned Olin with a
complete line of improved 20MM, 25MM and 30MM ammunition as well as air
dispensed munitions products.
 
  In May 1994, Olin issued approximately 2.2 million shares of its common stock
in an underwritten public offering at $46 per share. The net proceeds of the
offering were used to fund the aforementioned acquisition and to retire short
term debt.
 
  In August 1994, Olin sold its conductive materials business to Acheson
Industries, including Olin's manufacturing facility in Ontario, California.
This business provided electrically conductive inks and coatings for membrane
switches and circuitry used in the electronics industry.
 
  In December 1994, Olin sold its trichloroisocyanurate production facility in
Lake Charles, Louisiana to BioLab Inc., a subsidiary of Great Lakes Chemical
Corp.
 
  In February 1995, Olin signed an agreement to sell its isocyanurate plant at
South Charleston, West Virginia and its Livonia, Michigan repackaging facility
to subsidiaries of Israel Chemicals Ltd. Previously, Olin entered into an
agreement to sell to Aqua Clear Industries, Inc. of Watervliet, New York, the
Sun(R) brand of swimming pool chemicals. Olin is required by an order of the
Federal Trade Commission (FTC) more fully discussed in Item 3(c) of this Form
10K, to divest itself of these assets. These sales are subject to the approval
of the FTC, among other things.
 
  On March 1, 1995, the 2.76 million shares of Olin's Series A Conversion
Preferred Stock (PERCS(R)) converted into shares of Olin's Common Stock on a
one-for-one basis.
 
INTERNATIONAL OPERATIONS
 
  Olin has sales offices and subsidiaries in various countries which support
the worldwide export of products from the United States as well as overseas
production facilities. In addition, Olin has manufacturing interests, both
direct and through joint ventures, in several foreign countries.
 
  An Olin subsidiary in Ireland manufactures biocides for personal care and
industrial applications; a Brazilian subsidiary manufactures urethane systems
and Reductone(R) sodium hydrosulfite. An electronic materials subsidiary
located in Belgium packages toners which are marketed throughout Europe.
Hydrochim, S.A., a wholly-owned subsidiary, is a French isocyanurate repacking
operation. Etoxyl, C.A., a Venezuelan subsidiary, manufactures urethane polyols
and other specialty chemicals.
 
  OCG Microelectronic Materials, a group of companies owned by Ciba-Geigy
Limited and Olin, markets photoresists, polyimides and other image forming
chemicals throughout Europe. A joint venture of OCG Microelectronic Materials,
Inc. and Fuji Photo Film Co., Ltd. manufactures photoresists in Japan and
markets them throughout the Far East.
 
  Nordesclor S.A., a joint venture with S.A. Industrias Votorantim, a Brazilian
company, manufactures calcium hypochlorite. Through a joint venture with
Sentrachem Limited, Olin has an interest in a plant in South Africa for the
production of HTH(R) pool chemicals.
 
  Olin has an interest in a plant in Japan for the production of urethane
polyols and other specialty chemicals through a joint venture with Asahi Glass
Company Ltd. Olin also has an interest in a plant in Venezuela for the
production of ethylene oxide and ethylene glycol through a joint venture with
Corimon, C.A., S.A.C.A., Petroquimica de Venezuela S.A. and the International
Finance Corporation. A joint venture of Olin and Asahi Glass Company Ltd. has
an interest in a TDI production plant in Japan with Mitsui Toatsu.

Australia. The geographic segment data contained in the Note "Segment
Information" of the Notes to Financial Statements on page 28 of the
Shareholders Report and Exhibit 13 hereto are incorporated by reference in this
Report.
 
CUSTOMERS AND DISTRIBUTION
 
  During 1994, no single nongovernmental customer accounted for more than 1.5%
of Olin's total consolidated sales and U.S. government sales accounted for 14%
of Olin's total consolidated sales. Products which Olin sells to industrial or
commercial users or distributors for use in the production of other products
constitute a major part of Olin's total sales. Some of its products, such as
pool chemicals, sporting ammunition and brass, are sold to a large number of
users or distributors, while others, such as certain industrial chemicals, are
sold in substantial quantities to a relatively small number of industrial
users.
 
  Most of Olin's products and services are marketed primarily through its sales
force and sold directly to various industrial customers, the U.S. Government
and its prime contractors, to wholesalers and other distributors.
 
  Chemicals. Principal customers of Olin's chemicals products include the pulp
and paper industries, vinyl chloride manufacturers, household and industrial
cleaner suppliers, municipal and industrial wastewater treatment companies,
specialty chemical manufacturers, flexible and rigid foam suppliers, automotive
companies, packaging suppliers, the refrigeration industry, manufacturers of
adhesives, coatings, elastomers and sealants, suppliers of various consumer
products including shampoos and swimming pool sanitizers, semiconductor
manufacturers, non-impact computer printer manufacturers and defense
contractors. Principal customers of Olin's interconnect materials business are
suppliers to semiconductor manufacturers and major computer and
telecommunications manufacturers.
 
  Metals. Principal customers of Olin's copper and copper alloy strip, sheet,
rod, wire and seamless and welded tube include producers of electrical and
electronic equipment, builders' hardware and appliances, the plumbing,
automotive and air-conditioning industries and manufacturers of a variety of
consumer goods.
 
  Olin manufactures cartridge brass for its ammunition business and for other
ammunition makers. Olin also serves numerous high-technology markets through a
thin-gauge reroll operation that produces stainless steels, high-temperature
alloys and glass sealing alloys, in addition to copper and copper alloys.
Posit-Bond(R) clad metal has made Olin a major supplier of metal to the U.S.
Mint. Olin also sells various alloys to foreign governments for coinage
purposes.
 
  The metal products business is also focused on the electronics market,
providing high performance and high quality materials needed by the electronics
industry and other advanced technology customers. These materials include Olin-
developed proprietary alloys and Copperbond(TM) treated copper foil marketed to
the printed circuit industry.
 
  Fabricated products are principally sold to ammunition manufacturers, the
U.S. Armed Forces, building product suppliers, household product manufacturers
and automotive manufacturers.
 
 
                                       8

 
  Defense and Ammunition. The principal customers of the Ordnance division are
the U.S. Department of Defense and certain foreign governments. Principal
customers of the Aerospace division are the U.S. Government, major defense
contractors, aerospace companies, telecommunications companies and certain
foreign governments. The principal users of the Winchester division's products
are recreational shooters, hunters, law enforcement agencies, the power and
concrete industries, the construction industry, the U.S. Armed Forces and
certain foreign governments.
 
GOVERNMENT SALES
 
  U.S. Government sales were approximately $379 million in 1994, $354 million
in 1993 and $409 million in 1992.
 
  Approximately 91% of such 1994 sales were to the Department of Defense or
agencies thereof. In addition, Olin operates certain Government owned plants,
including the Lake City Army Ammunition Plant in Independence, Missouri, for
which Olin receives fee income. Products and services sold to the Government,
to Government contractors or friendly foreign governments include ammunition,
propellant and specialty defense products and services. Olin also manufactures
and blends hydrazine based fuels for the Government for use as a propellant for
the Space Shuttle, satellites and expendable launch vehicles. The U.S. Mint
purchases cupronickel for nickels and Posit-Bond(R) clad metal for other U.S.
coins. Ammunition cups and strip are sold to Government contractors for
ultimate delivery to the Government.
 
  Olin's Government business is performed under both cost reimbursement and
fixed price contracts. Cost reimbursement contracts provide for the
reimbursement of allowable costs plus the payment of a fixed fee, an incentive
fee based upon actual performance as compared to contractual targets, or an
award fee based upon unilateral evaluation by the Government. Olin's fixed
price contracts are either firm fixed price contracts or incentive contracts
under which Olin shares certain savings or overruns with the Government.
 
  Government contracts generally have provisions for audit by the Government,
and cost reimbursement contracts have limitations on reimbursable costs.
Contracts may be terminated at the Government's convenience upon payment of
certain termination costs and, in some cases, profits.
 
  Because several of its divisions engage in government contracting activities
and make sales to the U.S. Government, Olin is subject to extensive and complex
U. S. government procurement laws and regulations. These laws and regulations
provide for government audits and reviews of contract procurement, performance
and administration. Failure to comply, even inadvertently, with these laws and
regulations and with laws governing the export of munitions and other
controlled products and commodities, could subject Olin or one or more of its
businesses to civil and criminal penalties, and under certain circumstances,
suspension and debarment from future government contracts for a specified
period of time.
 
  Changes in the strategic direction of defense spending, the timing of defense
procurements and specific defense program appropriation decisions may adversely
affect the performance of the Defense and Ammunition segment and Olin in future
years, including its income, liquidity, capital resources and financial
condition. The precise impact of these decisions will depend upon the timing
and size of changes and decisions, and Olin's ability to mitigate their impact
with new business, business consolidations or cost reductions. Olin currently
provides services to the U.S. Government in facilities management and ordnance
demilitarization and continues to pursue other business areas. In view of
continuing uncertainty regarding the strategy and priorities of the Department
of Defense, the historical financial information of the Defense and Ammunition
segment and, to a lesser extent, of Olin, may not be indicative of future
performance.

COMPETITION
 
  Olin is in active competition with businesses producing the same or similar
products, as well as, in some instances, with businesses producing different
products designed for the same uses. With respect to certain product groups,
such as ammunition and copper alloys, and with respect to certain individual
products, such as pool chemicals, chlor-alkali and urethane products, Olin is
one of the largest manufacturers or distributors in the United States. With
respect to its many other products, Olin's share of total domestic sales varies
greatly.
 
EMPLOYEES
 
  As of December 31, 1994, Olin had approximately 12,800 employees (excluding
approximately 1,300 employees at Government owned contractor operated
facilities), approximately 12,300 of whom were working in the United States and
approximately 500 of whom were working in foreign countries. A majority of the
hourly paid employees are represented, for purposes of collective bargaining,
by various labor unions. Some labor contracts extend for as long as four years,
but during each year new agreements must be negotiated in a number of Olin's
plants. One major labor contract was renewed in 1994. Five major collective
bargaining agreements at its East Alton, Illinois facility will expire in 1995.
While relations between Olin and its employees and their various
representatives are generally considered satisfactory, there can be no
assurance that new labor contracts can be concluded without work stoppages. No
major work stoppages have occurred in the last three years.
 
RESEARCH ACTIVITIES; PATENTS
 
  Olin's research activities are conducted both on a product group and
corporate-wide basis at a number of facilities. Company sponsored research
expenditures were approximately $35 million during 1994, $41 million during
1993 and $39 million during 1992. Customer sponsored research expenditures
(primarily U.S. Government) were approximately $79 million in 1994, $88 million
in 1993 and $84 million in 1992.
 
  Olin owns, or is licensed under, a number of patents, patent applications and
trade secrets covering its products and processes. Olin believes that, in the
aggregate, the rights under such patents and licenses are important to its
operations, but does not consider any patent or license or group thereof
related to a specific process or product to be of material importance when
viewed from the standpoint of Olin's total business.
 
RAW MATERIALS AND ENERGY
 
  Olin purchases the major portion of its raw material requirements. The
principal basic raw materials required by Olin for its production of chemicals
are various hydrocarbons, salt, lime, electricity, propylene oxide, ethylene
oxide, natural gas, toluene, sulfur, ammonia and urea. Copper, zinc and various
other nonferrous metals are required for the metals business. Lead, brass and
propellant are the principal raw materials used in the ammunition business.
Olin's principal basic raw materials are typically purchased pursuant to
multiyear contracts. In addition, Olin uses many chemicals produced in its own
operations as raw materials, intermediates or processing agents in the
production of various other chemical products. In the manufacture of
ammunition, Olin uses a substantial percentage of its own output of smokeless
powder and cartridge brass. Additional information with respect to specific raw
materials is set forth in the table above under the caption entitled "Products
and Services."
 
  Electricity is the predominant energy source for Olin's manufacturing
facilities. Most of Olin's facilities are served by utilities which generate
electricity principally from coal and nuclear power.
 
                                       10

 
ENVIRONMENTAL AND TOXIC SUBSTANCES CONTROLS
 
  The establishment and implementation of federal, state and local standards to
regulate air, water and land quality has affected and will continue to affect
substantially all of Olin's plants. Facilities and equipment to protect the
environment do not inherently produce any significant increase in product
capacity, efficiency or revenue, and their operation generally entails
additional expense and energy consumption. Federal legislation providing for
regulation of the manufacture, transportation, use and disposal of hazardous
and toxic substances has imposed additional regulatory requirements on
industry, particularly the chemicals industry. In addition, implementation of
environmental laws, such as the Resource Conservation and Recovery Act and the
Clean Air Act, has required and will continue to require new capital
expenditures and will increase operating costs. Olin employs waste minimization
and pollution prevention programs at its manufacturing sites. In order to help
finance the cleanup of waste disposal sites, the Comprehensive Environmental
Response, Compensation and Liability Act of 1980, as amended by the Superfund
Amendments and Reauthorization Act of 1986 ("Superfund"), imposes a tax on the
sale of various chemicals, including chlorine, caustic and certain other
chemicals produced by Olin, and on the disposal of certain hazardous wastes.
 
  Olin is party to various governmental and private environmental actions
associated with waste disposal sites and manufacturing facilities. Associated
costs of investigatory and remedial activities are provided for in accordance
with generally accepted accounting principles governing probability and the
ability to reasonably estimate future costs. Environmental provisions charged
to income amounted to $17 million in 1994, $85 million in 1993 and $17 million
in 1992. The significant increase in 1993 resulted from expanded volumes of
contaminants uncovered while remediating a particular site, at which excavation
is now complete, combined with the availability of more definitive data from
progressing investigatory activities concerning both the nature and extent of
contamination and remediation alternatives at other sites. Charges to income
for investigatory and remedial efforts were material to operating results in
1994, 1993 and 1992 and may be material to net income in future years.
 
  Cash outlays for environmental-related activities totalled $82 million in
1994 as compared with $93 million in 1993 and $103 million in 1992. During
1994, $45 million of these cash outlays were directed towards normal plant
operations for the disposal of waste and the installation, operation and
maintenance of pollution control equipment and facilities to ensure compliance
with mandated and voluntarily imposed environmental quality standards.
Comparable spending for 1993 and 1992 was $49 million and $62 million,
respectively. Included in the costs for normal plant operations were
environmental capital expenditures for pollution control equipment and
pollution abatement facilities. Spending for environmental capital expenditures
was $11 million in both 1994 and 1993 and $25 million in 1992. The 1992
environmental capital expenditures include construction costs for a waste water
treatment facility at Olin's Lake Charles plant. Historically, Olin has funded
its environmental capital expenditures through cash flow from operations and
expects to do so in the future.
 
  Cash outlays for remedial and investigatory activities associated with former
waste sites and past operations were $37 million in 1994, $44 million in 1993
and $41 million in 1992. These amounts were not charged to income but instead
were charged to reserves established for such costs identified and expensed to
income in prior years.
 
  Olin's estimated environmental liability at the end of 1994 was attributable
to 78 sites, 33 of which were on the National Priority List ("NPL"). Twelve
sites accounted for approximately 75% of such liability and, of the remaining
sites, no one site accounted for more than three percent of such liability. Six
of these twelve sites were in the investigatory stage of the remediation
process. In this stage, remedial investigation and feasibility studies are
conducted by either Olin, the United States Environmental Protection Agency
("EPA") or other potentially responsible parties ("PRP's") and a Record of
Decision ("ROD") or its equivalent has not been issued. At another three of the
twelve sites, a ROD or its equivalent has been issued by either the EPA or
responsible state agency and Olin either
 
                                       11

 
alone, or as a member of a PRP group, was engaged in performing the remedial
measures required by that ROD. At the remaining three of the twelve sites, part
of the site is subject to a ROD and another part is still in the investigative
stage of remediation. All twelve sites were either former manufacturing
facilities or waste sites containing contamination generated by those
facilities.
 
  Total environmental-related cash outlays for 1995 are estimated to be $93
million, of which $53 million is expected to be spent on normal plant
operations, including $15 million on capital projects, and $40 million on
investigatory and remedial efforts.
 
  Annual environmental-related cash outlays for capital projects, site
investigation and remediation, and normal plant operations are expected to
range between $90-$105 million over the next several years. While Olin does not
anticipate a material increase in the projected annual level of its
environmental-related costs, there is always the possibility that such
increases may occur in the future in view of the uncertainties associated with
environmental exposures. Environmental exposures are difficult to assess for
numerous reasons, including the identification of new sites, developments at
sites resulting from investigatory studies, advances in technology, changes in
environmental laws and regulations and their application, the scarcity of
reliable data pertaining to identified sites, the difficulty in assessing the
involvement and financial capability of other potentially responsible parties
and Olin's ability to obtain contributions from other parties and the time
periods (sometimes lengthy) over which site remediation occurs. It is possible
that some of these matters (the outcomes of which are subject to various
uncertainties) may be resolved unfavorably against Olin.
 
  See also Item 3, Legal Proceedings below, the Note "Environmental" of the
Notes to Financial Statements contained in the Shareholders Report and Exhibit
13 hereto, and "Management's Discussion and Analysis of Financial Condition and
Results of Operations" incorporated in this Report for additional information
regarding environmental matters affecting Olin.
 
ITEM 2. PROPERTIES
 
  Olin has plants at 34 separate locations in 20 states and 4 plants in 4
foreign countries. Most plants are owned; a number of small plants and portions
of one major plant are leased. Listed under Item 1 above in the table set forth
under the caption "Products and Services" are the locations at or from which
Olin's products and services are manufactured, distributed or marketed by
segment.
 
  Olin leases warehouses, terminals and distribution offices and space for
executive and branch sales offices and service departments throughout the
country and overseas.
 
ITEM 3. LEGAL PROCEEDINGS
 
  (a) In December 1979, an action was commenced in the U.S. District Court in
New York by the United States against Occidental Chemical Corporation (then
known as Hooker Chemical & Plastics Corporation) ("Oxychem"), certain related
companies, Olin and the City of Niagara Falls, New York, alleging that chemical
wastes are migrating in violation of environmental laws or regulations from a
site in Niagara Falls where Oxychem and Olin own adjacent, inactive chemical
waste landfills. The United States is seeking injunctive relief and an order
requiring Oxychem and Olin, among other things, to secure the landfill site,
install a leachate collection system and treat whatever leachate is collected,
as well as an order requiring Oxychem and Olin to place $16.5 million in trust
or provide a bond to ensure that the site will be secured. The United States is
also seeking civil penalties for each day of alleged violation of the Clean
Water Act which currently has a maximum daily penalty of $25,000.
 
  In November 1980, the State of New York filed a complaint as co-plaintiff in
the same action based upon essentially the same factual allegations as in the
suit brought by the United States. The State is seeking $100 million
compensatory damages and $100 million punitive damages. The State is seeking
$100 million compensatory damages and $100 million punitive damages. The State
is also requesting
 
                                       12

 
a court order to abate the alleged nuisance and penalties of $10,000 per day
for alleged violations of each of four provisions of New York's Environmental
Conservation Law. In 1983, the State filed a motion to amend its complaint to
include a count under CERCLA (Comprehensive Environmental Response,
Compensation and Liability Act of 1980) alleging damage to natural resources.
In 1986, the Department of Justice filed a motion to amend its complaint to
include a CERCLA and SARA (Superfund Amendments and Reauthorization Act of
1986) count. Oxychem and Olin have filed in opposition to the motions and the
court has deferred a ruling on both motions.
 
  The U.S. Environmental Protection Agency ("EPA") notified Olin and Oxychem of
an aggregate of $3,050,000 in agency oversight costs on the project.
 
  Under a stipulation entered into by all parties in 1984, Olin and Oxychem
undertook a site remedial investigation which was completed in October 1988.
Subsequently, the parties entered into a further stipulation under which
Oxychem and Olin conducted a feasibility study of possible remedial measures.
Olin does not expect these stipulations to have any further effect on the
outcome of this matter. The remedial investigation and feasibility study was
completed in July 1990. On September 24, 1990, EPA issued a Proposed Remedial
Action Plan and on September 29, 1990 a Record of Decision ("ROD"). The EPA
selected remedy was estimated to cost $30 million. On September 30, 1991, the
EPA issued an administrative order directing Olin and Oxychem to implement the
remedy identified in the September 29, 1990 Record of Decision. Olin and
Oxychem have agreed to perform the remedy identified on such order. The cost of
any remedy is expected to be shared by Olin and Oxychem in an agreed-upon
proportion. Olin believes that any liability incurred by it in this matter will
not be materially adverse to its financial condition.
 
  (b) In June 1987, the EPA issued a ROD recommending remedial actions and
ecological studies with respect to mercury contamination at the site of Olin's
former mercury cell chlor-alkali plant in Saltville, Virginia. In August 1987,
EPA, under Section 122 of CERCLA, asked Olin to undertake the work called for
in the ROD, and Olin agreed to do so. Olin's commitment was required to be
incorporated into a Consent Decree to be filed with a federal district court.
EPA's draft of the Consent Decree included a proposed $1.4 million Clean Water
Act penalty for past unpermitted discharges from a muck pond at the site, as
well as $570,000 in reimbursement of past EPA costs. In response to Olin's
request, EPA has agreed to reduce the costs to $456,000 and to sever the
penalty from the CERCLA action, making it the subject of separate negotiations
after execution of the Consent Decree. In 1988, the proposed $1.4 million Clean
Water Act penalty was severed from the Consent Decree entered into by Olin and
filed with the U.S. District Court for the Western District of Virginia, and
the EPA has taken no further action with respect to any proposed penalty.
Pursuant to the Decree, in November, 1988 Olin submitted to EPA, Region III, a
work plan for remedial action, including additional stormwater run-on control
around Pond #5 and construction of a wastewater treatment plant for the outfall
from Pond #5. Olin also submitted for EPA approval a work plan for further
remedial investigation of the impact of mercury from the site on groundwater
flowing into the North Fork Holston River and its sediment from the site to a
point twenty-seven miles downstream at the Tennessee border. During 1989 work
plans pursuant to the Consent Decree between EPA and Olin were approved by EPA.
Final payment of past EPA costs of $228,000 plus interest was made on November
21, 1989, in accordance with the Consent Decree.
 
  On September 5, 1991, EPA advised Olin of potential liability for
contaminated soils which were being removed in conjunction with construction of
the Rte. 634 bridge in Saltville. Olin and EPA signed a Consent Order
authorizing Olin to do the soil removal, which has been completed.
 
  Olin has completed the remedial investigation and feasibility study of the
former plant site, including Ponds # 5 and 6. On January 18, 1995, EPA issued a
Proposed Remedial Action Plan for a 30-day public comment period. The plan
calls for a cap to be constructed over Pond #5, and the excavation of soil and
sediment from the former chlorine plant site. Olin will be filing comments with
EPA in support of less expensive but it believes equally effective alternatives
for remediating the site.
 
                                       13

 
  On August 29, 1994, EPA notified Olin of the company's potential liability
with respect to the "Graveyard Dump Site", located north of the former plant
site. The site is relatively small, occupying about one half acre. EPA's
investigation found about 20 capacitors and miscellaneous debris scattered
around the site as well as evidence of PCB contamination in the soils.
 
  Negotiations with EPA ensued and Olin and EPA signed an Administrative Order
by Consent, effective January 5, 1995, in which Olin agreed to perform certain
response activities at the site, primarily the removal and disposal of PCB
contaminated electrical equipment and soils. Planning for the work is underway
and it is expected that the work will take place in the winter/spring of 1995.
 
  Olin believes that any liability incurred by it in this matter will not be
materially adverse to its financial condition.
 
  (c) In December 1987, a Federal Trade Commission ("FTC") administrative law
judge ruled that Olin must divest the chlorinated isocyanurates business
acquired in 1985, which includes an isocyanurates manufacturing facility in
South Charleston, West Virginia, a packaging facility in Livonia, Michigan and
the Sun(R) brand trademark. The ruling stated that the acquisition was likely
to lessen competition in markets for chlorinated isocyanurates and calcium
hypochlorite dry swimming pool sanitizers. Olin appealed this decision to the
FTC. In July 1990, the FTC announced that it had issued an order denying Olin's
appeal and requiring Olin to divest itself of such business within one year of
the order becoming final following appeal. Olin appealed the FTC decision to
the U.S. Court of Appeals. The U.S. Court of Appeals upheld the FTC decision on
February 26, 1993. Olin petitioned for review by the U.S. Supreme Court and
such petition was denied. Olin unsuccessfully attempted to modify the FTC order
by proposing to the FTC that Olin sell its trichloroisocyanurate production
facility in Lake Charles, Louisiana to BioLab, Inc. (a sale which it ultimately
consummated in 1994) instead of selling its South Charleston facilities. Olin
is in the process of divesting the assets of this business to various entities
in compliance with the FTC order.
 
  Olin believes that the divestment of this business will not be materially
adverse to its financial condition or results of operations.
 
  (d) As part of the continuing environmental investigation by Federal, state
and local governments of waste disposal sites, Olin has entered into a number
of settlement agreements requiring it to contribute to the cost of the
investigation and cleanup of a number of sites. This process of investigation
and cleanup is expected to continue.
 
  (e) Olin and its subsidiaries are defendants in various other legal actions
arising out of their normal business activities, none of which is considered by
management to be material.
