1993 DEVELOPMENTS

In December 1993, Olin announced a series of strategic actions, consisting of
personnel reductions, business restructurings, including consolidations and re-
alignments within divisions, provisions for costs at sites of discontinued
businesses, future environmental liabilities and other charges. As a result of
these actions, Olin recorded a pre-tax charge to earnings of $213 million ($132
million aftertax) in the fourth quarter of 1993.

On October 1, 1993, Olin sold its interest in Langenberg Kupfer und
Messingwerke GmbH & Co KG to its partner, Wieland-Werke AG, and in so doing
dissolved their four-year old German joint venture partnership. The companies
will continue joint research and development activities, and Wieland will
market certain Olin alloys in Europe.

In July 1993, Olin and GenCorp Inc. announced that they are holding
discussions regarding the possible acquisition by Olin of certain assets of the
medium caliber ordnance business of GenCorp Inc. To date, the companies have
not reached a definitive agreement. Discussions are continuing and any
agreement would be subject to a number of conditions including approval by the
boards of directors of both companies.

INTERNATIONAL OPERATIONS

Olin has sales offices and subsidiaries in various countries which support the
worldwide export of products from the United States as well as overseas
production facilities. In addition, Olin has manufacturing interests, both
direct and through joint ventures, in several foreign countries.

An Olin subsidiary in Ireland manufactures biocides for personal care and
industrial applications; a Brazilian subsidiary manufactures urethane systems
and Reductone(R) sodium hydrosulfite. An Olin Hunt subsidiary located in
Belgium packages toners which are marketed throughout Europe. OCG
Microelectronic Materials, a group of companies owned by Ciba-Geigy Limited and
Olin, markets photoresists, polyimides and other image forming chemicals
throughout Europe. A joint venture of OCG Microelectronic Materials, Inc. and
Fuji Photo Film Co., Ltd. manufactures photoresists in Japan and markets them
throughout the Far East.

Nordesclor S.A., a joint venture with S.A. Industrias Votorantim, a Brazilian
company, manufactures calcium hypochlorite. Through a joint venture with
Sentrachem Limited, Olin has an interest in a plant in South Africa for the
production of HTH(R) pool chemicals. Olin holds a 100% interest in Hydrochim,
S.A. a French chloroisocyanurate repacking operation.

Olin has interests in plants in Japan and Venezuela for the production of
urethane polyols and other specialty chemicals through joint ventures with
Asahi Glass Company Ltd. and Corimon, C.A.S.A.C.A., respectively. Olin also has
an interest in a plant recently completed in Venezuela for the production of
ethylene oxide and ethylene glycol through a joint venture with Corimon,
C.A.S.A.C.A., Petroquimica de Venezuela S.A. and the International Finance
Corporation. A joint venture of Olin and Asahi Glass Company Ltd. has an
interest in a TDI production plant in Japan with Mitsui Toatsu.

Yamaha-Olin Metal Corporation, a joint venture with Yamaha Corporation,
manufactures high-performance copper alloys in Japan for sale to the
electronics industry throughout the Far East.

Techniche Olin Limited, a joint venture with a U.K. company, manufactures
shaped charge cones in Coventry, England and markets them to prime contractors
for inclusion in armor piercing munitions for certain West European countries.

An Olin subsidiary loads and packs sporting and industrial ammunition in
Australia.

The geographic segment data contained in the Note "Segment Information" of
the Notes to Financial Statements on pages 28 and 29 of the 1993 Shareholders
Report and Exhibit 13 hereto are incorporated by reference in this Report.

CUSTOMERS AND DISTRIBUTION

During 1993, no single nongovernmental customer accounted for more than 2% of
Olin's total consolidated sales and U. S. government sales accounted for 15% of
Olin's total consolidated sales. Products which Olin sells to industrial or
commercial users or distributors for use in the production of other products
constitute a major part of Olin's total sales. Some of its products, such as
pool chemicals, sporting ammunition and brass, are sold to a large number of
users or distributors, while others, such as certain industrial chemicals, are
sold in substantial quantities to a relatively small number of industrial
users.

Most of Olin's products and services are marketed primarily through its sales
force and sold directly to various industrial customers, the U.S. Government
and its prime contractors to wholesalers and other distributors.

Chemicals. Principal customers of Olin's chemicals products include the pulp
and paper industries, vinyl chloride manufacturers, household and industrial
cleaner suppliers, municipal and industrial wastewater treatment companies,
specialty chemical manufacturers, flexible and rigid foam suppliers, automotive
companies, packaging suppliers, the refrigeration industry, manufacturers of
adhesives, coatings, elastomers and sealants, suppliers of various consumer
products including shampoos and swimming pool sanitizers, semiconductor
manufacturers, non-impact computer printer manufacturers and defense
contractors. Principal customers of Olin's interconnect materials business are
suppliers to semiconductor manufacturers and major computer and
telecommunications manufacturers.

Metals. Principal customers of Olin's copper and copper alloy strip, sheet
and rod and seamless and welded tube include producers of electrical and
electronic equipment, builders' hardware and appliances, the plumbing,
automotive and air-conditioning industries and manufacturers of a variety of
consumer goods.

Olin manufactures cartridge brass for its ammunition business and for other
ammunition makers. Olin also serves numerous high-technology markets through a
thin-gauge reroll operation that produces stainless steels, high-temperature
alloys and glass sealing alloys, in addition to copper and copper alloys.
Posit-Bond(R) clad metal has made Olin a major supplier of metal to the U.S.
Mint. Olin also sells various alloys to foreign governments for coinage
purposes.

The metal products business is also focused on the electronics market,
providing high performance and high quality materials needed by the electronics
industry and other advanced technology customers. These materials include Olin-
developed proprietary alloys and Copperbond(TM) treated copper foil marketed to
the printed circuit industry.

Fabricated products are principally sold to ammunition manufacturers, the
U.S. Armed Forces, building product suppliers, household product manufacturers
and automotive manufacturers.

Defense and Ammunition. The principal customers of the Ordnance division are
the U.S. Department of Defense and certain foreign governments. Principal
customers of the Aerospace division are the U.S. Government, major defense
contractors, aerospace companies and certain foreign governments. The principal
users of the Winchester division's products are recreational shooters, hunters,
law enforcement agencies, the power and concrete industries, the construction
industry, the U.S. Armed Forces and certain foreign governments.

GOVERNMENT SALES

U.S. Government sales were approximately $354 million in 1993, $409 million
in 1992 and $453 million in 1991.

Approximately 89% of such 1993 sales were to the Department of Defense or
agencies thereof. In addition, Olin operates certain Government owned plants,
including the Lake City Army Ammunition Plant in Independence, Missouri, for
which Olin receives fee income. Products and services sold to the Government,
to Government contractors or friendly foreign governments include ammunition,
propellant and specialty defense products and services. Olin also manufactures
and blends hydrazine based fuels for the Government for use as a propellant for
the Space Shuttle, satellites and expendable launch vehicles. The U.S. Mint
purchases cupronickel for nickels and Posit-Bond(R) clad metal for other U.S.
coins. Ammunition cups and strip are sold to Government contractors for
ultimate delivery to the Government.

Olin's Government business is performed under both cost reimbursement and
fixed price contracts. Cost reimbursement contracts provide for the
reimbursement of allowable costs plus the payment of a fixed fee, an incentive
fee based upon actual performance as compared to contractual targets, or an
award fee based upon unilateral evaluation by the Government. Olin's fixed
price contracts are either firm fixed price contracts or incentive contracts
under which Olin shares certain savings or overruns with the Government.

Government contracts generally have provisions for audit by the Government,
and cost reimbursement contracts have limitations on reimbursable costs.
Contracts may be terminated at the Government's convenience upon payment of
certain termination costs and, in some cases, profits. Olin's Government
business is subject to Government procurement regulations.

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

COMPETITION

Olin is in active competition with businesses producing the same or similar
products, as well as, in some instances, with businesses producing different
products designed for the same uses. With respect to certain product groups,
such as ammunition and copper alloys, and with respect to certain individual
products, such as pool chemicals, chlor-alkali and urethane products, Olin is
one of the largest manufacturers or distributors in the United States. With
respect to its many other products, Olin's share of total domestic sales varies
greatly.

EMPLOYEES

As of December 31, 1993, Olin had approximately 12,438 employees (excluding
approximately 1,529 employees at Government owned contractor operated
facilities), approximately 11,878 of whom

9


were working in the United States and approximately 560 of whom were working in
foreign countries. A majority of the hourly paid employees are represented, for
purposes of collective bargaining, by various labor unions. Some labor
contracts extend for as long as four years, but during each year new agreements
must be negotiated in a number of Olin's plants. Two major labor contracts were
renewed in 1993. One major collective bargaining agreement will expire in 1994.
While relations between Olin and its employees and their various
representatives are generally considered satisfactory, there can be no
assurance that new labor contracts can be concluded without work stoppages. No
major work stoppages have occurred in the last three years.

RESEARCH ACTIVITIES; PATENTS

Olin's research activities are conducted both on a product group and
corporate-wide basis at a number of facilities. Company sponsored research
expenditures were approximately $41 million during 1993, $39 million during
1992 and $41 million during 1991. Customer sponsored research expenditures
(primarily U.S. Government) were approximately $88 million in 1993, $84 million
in 1992 and $71 million in 1991.

Olin owns, or is licensed under, a number of patents, patent applications and
trade secrets covering its products and processes. Olin believes that, in the
aggregate, the rights under such patents and licenses are important to its
operations, but does not consider any patent or license or group thereof
related to a specific process or product to be of material importance when
viewed from the standpoint of Olin's total business.

RAW MATERIALS AND ENERGY

Olin purchases the major portion of its raw material requirements. The
principal basic raw materials required by Olin for its production of chemicals
are various hydrocarbons, salt, lime, electricity, proplylene oxide, ethylene
oxide, natural gas, toluene, sulfur, ammonia and urea. Copper, zinc and various
other nonferrous metals are required for the metals business. Lead, brass and
propellant are the principal raw materials used in the ammunition business.
Olin's principal basic raw materials are typically purchased pursuant to
multiyear contracts. In addition, Olin uses many chemicals produced in its own
operations as raw materials, intermediates or processing agents in the
production of various other chemical products. In the manufacture of
ammunition, Olin uses a substantial percentage of its own output of smokeless
powder and cartridge brass. Additional information with respect to specific raw
materials is set forth in the table above under the caption entitled "Products
and Services."

Electricity is the predominant energy source for Olin's manufacturing
facilities. Olin's facilities are served by utilities which generate
electricity principally from coal and natural gas.

ENVIRONMENTAL AND TOXIC SUBSTANCES CONTROLS

The establishment and implementation of federal, state and local standards to
regulate air, water and land quality has affected and will continue to affect
substantially all of Olin's plants. Facilities and equipment to protect the
environment do not inherently produce any significant increase in product
capacity, efficiency or revenue, and their operation generally entails
additional expense and energy consumption. Federal legislation providing for
regulation of the manufacture, transportation, use and disposal of hazardous
and toxic substances has imposed additional regulatory requirements on
industry, particularly the chemicals industry. In addition, implementation of
environmental laws, such as the Resource Conservation and Recovery Act and the
Clean Air Act, has required and will continue to require new capital
expenditures and will increase operating costs. Olin employs waste minimization
and pollution prevention programs at its manufacturing sites. In order to help
finance the cleanup of waste disposal sites, the Comprehensive Environmental
Response, Compensation and Liability Act of 1980, as amended by the Superfund
Amendments and Reauthorization Act of 1986 ("Superfund"),

10


imposes a tax on the sale of various chemicals, including chlorine, caustic and
certain other chemicals produced by Olin, and on the disposal of certain
hazardous wastes.

Olin is party to various governmental and private environmental actions
associated with waste disposal sites and manufacturing facilities. Associated
costs of investigatory and remedial activities are provided for in accordance
with generally accepted accounting principles governing probability and the
ability to reasonably estimate future costs. Environmental provisions charged
to income amounted to $85 million in 1993, $17 million in 1992, and $18 million
in 1991. The significant increase in 1993 resulted from expanded volumes of
contaminants uncovered while remediating a particular site, combined with the
availability of more definitive data from progressing investigatory activities
concerning both the nature and extent of contamination and remediation
alternatives at other sites. Charges to income for investigatory and remedial
efforts were material to operating results in 1993, 1992, and 1991 and may be
material to net income in future years.

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

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

Olin's estimated environmental liability at the end of 1993 was attributable
to 70 sites, 34 of which were on the National Priority List ("NPL"). Ten sites
accounted for approximately 75% of such liability and, of the remaining sites,
no one site accounted for more than three percent of such liability. Four of
these ten sites were in the investigatory stage of the remediation process. In
this stage, remedial investigation and feasibility studies are conducted by
either Olin, the United States Environmental Protection Agency ("EPA") or other
potentially responsible parties ("PRP's"). At another four of the ten sites, a
Record of Decision ("ROD") or its equivalent has been issued by either the EPA
or responsible state agency and Olin either alone, or as a member of a PRP
group, was engaged in performing the remedial measures required by that ROD. At
the remaining two of the ten sites, part of the site is subject to a ROD and
another part is still in the investigative stage of remediation. All ten sites
were either former manufacturing facilities or waste sites containing
contamination generated by those facilities.

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

Annual environmental-related cash outlays for capital projects, site
investigation and remediation, and normal plant operations are expected to
range between $90-$105 million over the next several years. While the company
does not anticipate a material increase in the projected annual level of its
environmental-related costs, there is always the possibility that such
increases may occur in the future

11


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

See also Item 3, Legal Proceedings below, the Note "Environmental" of the
Notes to Financial Statements contained in the 1993 Shareholders Report and
Exhibit 13 hereto, and "Management's Discussion and Analysis of Financial
Condition and Results of Operations" incorporated in this Report for additional
information regarding environmental matters affecting Olin.

ITEM 2. PROPERTIES

Olin has plants at 35 separate locations in 20 states and 3 plants in 3
foreign countries. Most plants are owned; a number of small plants and portions
of one major plant are leased. Listed under Item 1 above in the table set forth
under the caption "Products and Services" are the locations at or from which
Olin's products and services are manufactured, distributed or marketed by
segment.

Olin leases warehouses, terminals and distribution offices and space for
executive and branch sales offices and service departments throughout the
country and overseas.

ITEM 3. LEGAL PROCEEDINGS

(a) In December 1979, an action was commenced in the U.S. District Court in
New York by the United States against Occidental Chemical Corporation (then
known as Hooker Chemical & Plastics Corporation) ("Oxychem"), certain related
companies, Olin and the City of Niagara Falls, New York, alleging that chemical
wastes are migrating in violation of environmental laws or regulations from a
site in Niagara Falls where Oxychem and Olin own adjacent, inactive chemical
waste landfills. The United States is seeking injunctive relief and an order
requiring Oxychem and Olin, among other things, to secure the landfill site,
install a leachate collection system and treat whatever leachate is collected,
as well as an order requiring Oxychem and Olin to place $16.5 million in trust
or provide a bond to ensure that the site will be secured. The United States is
also seeking civil penalties for each day of alleged violation of the Clean
Water Act which currently has a maximum daily penalty of $25,000.

In November 1980, the State of New York filed a complaint as co-plaintiff in
the same action based upon essentially the same factual allegations as in the
suit brought by the United States. The State is seeking $100 million
compensatory damages and $100 million punitive damages. The State is also
requesting a court order to abate the alleged nuisance and penalties of $10,000
per day for alleged violations of each of four provisions of New York's
Environmental Conservation Law. In 1983, the State filed a motion to amend its
complaint to include a count under CERCLA (Comprehensive Environmental
Response, Compensation and Liability Act of 1980) alleging damage to natural
resources. In 1986, the Department of Justice filed a motion to amend its
complaint to include a CERCLA and SARA (Superfund Amendments and
Reauthorization Act of 1986) count. Oxychem and Olin have filed in opposition
to the motions and the court has deferred a ruling on both motions.

The U.S. Environmental Protection Agency ("EPA") notified Olin and Oxychem of
an aggregate of $3,050,000 in agency oversight costs on the project.

Under a stipulation entered into by all parties in 1984, Olin and Oxychem
undertook a site remedial investigation which was completed in October 1988.
Subsequently, the parties entered into a further

12


stipulation under which Oxychem and Olin conducted a feasibility study of
possible remedial measures. Olin does not expect these stipulations to have any
further effect on the outcome of this matter. The remedial investigation and
feasibility study was completed in July 1990. On September 24, 1990, EPA issued
a Proposed Remedial Action Plan and on September 29, 1990 a Record of Decision
("ROD"). The EPA selected remedy was estimated to cost $30 million. On
September 30, 1991, the EPA issued an administrative order directing Olin and
Oxychem to implement the remedy identified in the September 29, 1990 Record of
Decision. Olin and Oxychem have agreed to perform the remedy identified on such
order. The cost of any remedy is expected to be shared by Olin and Oxychem in
an agreed-upon proportion. Olin believes that any liability incurred by it in
this matter will not materially affect its financial condition.

(b) In June 1987, the EPA issued a ROD recommending remedial actions and
ecological studies with respect to mercury contamination at the site of Olin's
former mercury cell chlor-alkali plant in Saltville, Virginia. In August 1987,
EPA, under Section 122 of CERCLA, asked Olin to undertake the work called for
in the ROD, and Olin agreed to do so. Olin's commitment was required to be
incorporated into a Consent Decree to be filed with a federal district court.
EPA's draft of the Consent Decree included a proposed $1.4 million Clean Water
Act penalty for past unpermitted discharges from a muck pond at the site, as
well as $570,000 in reimbursement of past EPA costs. In response to Olin's
request, EPA has agreed to reduce the costs to $456,000 and to sever the
penalty from the CERCLA action, making it the subject of separate negotiations
after execution of the Consent Decree. In 1988, the proposed $1.4 million Clean
Water Act penalty was severed from the Consent Decree entered into by Olin and
filed with the U.S. District Court for the Western District of Virginia, and
the EPA has taken no further action with respect to any proposed penalty.

(c) In December 1987, a Federal Trade Commission ("FTC") administrative law
judge ruled that Olin must divest the chlorinated isocyanurates business
acquired from FMC Corporation in 1985, which includes isocyanurates
manufacturing and packaging and the Sun(R) brand trademark. The ruling stated
that the acquisition lessened competition in markets for chlorinated
isocyanurates and calcium hypochlorite dry swimming pool sanitizers. Olin
appealed this decision to the FTC. In July 1990, the FTC announced that it had
issued an order denying Olin's appeal and requiring Olin to divest itself of
such business within one year of the order becoming final following appeal.
Olin has appealed the FTC decision to the U.S. Court of Appeals. The U.S. Court
of Appeals upheld the FTC decision on February 26, 1993 and Olin's petition for
en banc review was denied. Olin petitioned for review by the U.S. Supreme Court
and such petition was denied.

Olin believes that a divestment of this business would not materially affect
its financial condition or results of operations.

(d) In late 1991, the EPA brought a civil action in the U.S. District Court
in Tennessee against Olin alleging violations of the Clean Air Act and
regulations thereunder with respect to mercury emissions at Olin's Charleston,
Tennessee plant. The complaint alleges, among other things, that Olin failed to
maintain a mercury cell in a manner to minimize leakage of mercury and mercury
contaminated material for a period of approximately 17 months. EPA claims civil
penalties of $25,000 per day for each alleged violation. Olin and EPA have
reached a settlement in principle in this matter pursuant to which Olin will
pay $1 million in penalties.

Olin believes that any liability incurred by it in this matter will not
materially affect its financial condition.

(e) As part of the continuing environmental investigation by Federal, state
and local governments of waste disposal sites, Olin has entered into a number
of settlement agreements requiring it to contribute to the cost of the
investigation and cleanup of a number of sites. This process of investigation
and cleanup is expected to continue.

13


(f) On November 21, 1989, a Massachusetts state trial court ruled in Augat,
Inc. and Isotronics v. Aegis, Inc., et al. that Aegis, Inc. ("Aegis") (a
Massachusetts corporation wholly owned by Olin-Asahi Interconnect Technologies)
and a certain individual were liable to plaintiffs on matters dealing with
employee solicitation and use of certain confidential information, which the
trial court found were violations of the Massachusetts Unfair Competition
statute. On January 16, 1991, the Supreme Judicial Court of Massachusetts
upheld in part and overturned in part the lower court decision. That court held
that the defendants were liable to the plaintiffs on the narrow ground that
they had induced an employee to breach his fiduciary duty to plaintiffs in
soliciting four other Isotronics employees to join Aegis while he was still
general manager. As a result the court ruled that defendants were liable to
plaintiffs for the Isotronics losses caused by problems arising from the
departure of key managerial employees who were approached by the employee while
he and they were still employed by Isotronics, provided that the losses were
caused by events occurring before Isotronics reasonably should have replaced
the departed managerial employees with competent people. The case was remanded
to the lower court for trial on damages.

After a trial on damages, the lower court entered a judgment on December 14,
1992 and subsequently modified, awarding plaintiffs $14 million in compensatory
damages, $14 million in non-compensatory damages, $10.7 million in interest,
$1.2 million in attorneys' fees, and $377,000 in costs. The judgment bears
interest at the rate of 12% per year. Defendants and plaintiffs have both
appealed. The Massachusetts Supreme Judicial Court agreed to hear the
defendants' appeal directly from the trial court and the parties are awaiting
the decision of such court.

Aegis was acquired in 1987 by Olin-Asahi Interconnect Technologies, a
partnership equally owned by subsidiaries and joint ventures of Olin and Asahi
Glass Co., Ltd., of Japan.

Although no allegation of wrongdoing has been made against Olin, Olin has
been named a "reach and apply" defendant under Massachusetts law in an attempt
by the plaintiffs to secure rights under a contractual obligation which may
result in a payment by Olin or one of its affiliates of a portion of whatever
the judgment is ultimately determined to be after appeal.

(g) Olin and its subsidiaries are defendants in various other legal actions
arising out of their normal business activities, none of which is considered by
management to be material.

INDEPENDENT AUDITORS' REPORT

TO THE BOARD OF DIRECTORS AND SHAREHOLDERS OF OLIN CORPORATION:

Under date of January 27, 1994, we reported on the consolidated balance
sheets of Olin Corporation and subsidiaries as of December 31, 1993 and 1992,
and the related consolidated statements of income, shareholders' equity and
cash flows for each of the years in the three-year period ended December 31,
1993, as contained in the 1993 Annual Report to Shareholders. Our report refers
to a change in accounting for postretirement benefits other than pensions and
income taxes in 1992. These consolidated financial statements and our report
thereon are incorporated by reference in the annual report on Form 10-K for the
year 1993. In connection with our audits of the aforementioned consolidated
financial statements, we also have audited the related financial statement
schedules as listed in Item 14(a)2 of the annual report on Form 10-K for the
year 1993. These financial statement schedules are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
financial statement schedules based on our audits.

In our opinion, such financial statement schedules, when considered in
relation to the basic consolidated financial statements taken as a whole,
present fairly, in all material respects, the information set forth therein.
