                                  THE COMPANY
 
GENERAL
 
  Cincinnati Financial, through its subsidiaries, has written commercial and
personal property and casualty insurance since 1951. The Company's insurance
subsidiaries are licensed to write property and casualty insurance in all 50
states and the District of Columbia but focus on the Midwest and Southeast
regions of the United States, where the Company believes it has a significant
presence. Cincinnati Financial's property and casualty operations generated
$1.5 billion of net premiums written in 1997 and accounted for 96% of the
Company's 1997 premium income. The Company had total assets of $9.5 billion
and shareholders' equity of $4.7 billion as of December 31, 1997. Cincinnati
Financial also provides life, health and accident insurance and, to a lesser
extent, financing and leasing services.
 
  The Company's property and casualty insurance subsidiaries are rated A++
(Superior) by A.M. Best Company ("A.M. Best"), placing them in the top 7% of
property and casualty insurers based on their A.M. Best ratings. These
subsidiaries also maintain AA+ (Excellent) claims-paying ability ratings from
Standard & Poor's Ratings Services, a division of The McGraw-Hill Company.
 
  Cincinnati Financial distributes its products through a limited number of
independent agencies (973 at December 31, 1997), a significant number of which
own shares of the Company's stock. The Company believes that its strong
relationship with and commitment to servicing these agencies are key elements
in the Company's successful business operations and expansion. Its network of
67 field marketing representatives provides a local presence for the Company
and strengthens the Company's relationships with its agents. The Company also
supports its independent agencies with competitive products, rates and
compensation. For example, the Company offers multi-year policy terms (i.e.,
three- to five-years) on many of its commercial and personal lines products.
In a 1997 independent survey of 30,000 agents and brokers across 16 commercial
product lines, the Company earned the highest overall score.
 
  Management has emphasized strict underwriting discipline and employee
productivity, and as a result, Cincinnati Financial has outperformed the
industry on an underwriting basis. The Company has achieved an average
combined ratio of 100.2% for the five years ended December 31, 1997, compared
to an industry average of 104.6% for the same period, based on industry data
provided by A.M. Best. Through the quarter ended December 31, 1997, the
Company had achieved an underwriting profit for the fifth consecutive quarter.
 
PROPERTY AND CASUALTY INSURANCE
 
  The Company's principal insurance subsidiary, The Cincinnati Insurance
Company ("CIC"), actively underwrites fire, automobile, casualty, bonds, and
related forms of property and casualty insurance in 27 states. The Company's
other property and casualty subsidiaries are The Cincinnati Casualty Company
("CCC"), which operates on a direct billing basis, and The Cincinnati
Indemnity Company ("Cincinnati Indemnity"), which markets nonstandard policies
for preferred risk accounts. Net written property and casualty premiums
totaled $1.5 billion for 1997, an increase of 6.4% over the prior year. The
combined ratio for the Company's property and casualty operations was 97.7%
for 1997.
 
 Commercial Insurance
 
  The Company generally targets small to medium-sized commercial accounts.
Cincinnati Financial's principal commercial lines products include commercial
multi-peril, commercial automobile and workers' compensation insurance, which
accounted for 36%, 20% and 19%, respectively, of 1997 commercial lines net
premiums written. The Company has generated $987.3 million of commercial lines
net premiums written in 1997, representing approximately 67% of the Company's
total property and casualty net premiums written.
 
 
                                       4

 
 Personal Insurance
 
  The Company's principal personal lines products include personal automobile
and homeowners' insurance, which accounted for 59% and 29%, respectively, of
1997 personal lines net premiums written. Automobile insurance products
include both physical damage and liability coverages. Cincinnati Financial
generated $483.3 million of personal lines net premiums written in 1997,
representing approximately 33% of the Company's total property and casualty
net premiums written.
 
 Underwriting
 
  The Company's field marketing representatives have primary responsibility
for the underwriting of policy submissions, which the Company believes allows
it to be more responsive to the needs of its independent agents and their
prospective insureds. The Company also believes that, given the nature of its
target market, its field marketing representatives are generally better able
to evaluate submissions than a centralized underwriting department. The
Company believes that its strict underwriting discipline has contributed to
its average combined ratio of 100.2% over the last five years, compared to the
industry average of 104.6%. Despite a competitive pricing environment,
especially within the commercial lines market, Cincinnati Financial was able
to achieve an underwriting profit in 1997 and its lowest combined ratio,
97.7%, since 1988.
 
 Distribution
 
  By being very selective in its choice of agents, the Company develops
stronger relationships, earns more loyalty and expects a higher percentage of
agency premium. Consequently, Cincinnati Financial is represented by fewer
than 1,000 independent agencies. A typical agency's total annual production is
between $4 million and $5 million. The Company estimates that it receives
approximately 40% of the total annual production of agencies with which it has
a developed relationship. Agents are supported by a team of 67 field marketing
representatives who work from their homes, thus eliminating the expense of
branch offices. The Company seeks to further strengthen relationships with its
independent agents through innovative commission structures which include a
profit-sharing program.
 
 Claims Management
 
  The Company is committed to providing timely, personal and fair management
of claims. Claims management is provided by over 600 field claims
representatives who have the authority to adjust most claims in the field. The
Company believes its decentralized claims adjusting process allows the Company
to be more responsive to its insureds and claimants. The Company also believes
an efficient and fair adjustment of claims further strengthens its
relationships with its independent agencies. The Company has developed a
number of successful claims management programs to help identify and manage
potential fraudulent claims.
 
 Reserves
 
  The Company's insurance reserve liabilities are estimated by Management
based upon Company experience data. The Company establishes property and
casualty insurance reserves, including adjustments of estimates, using
information from internal analysis and review by external actuaries, who
perform an annual review of the Company's reserves. The Company believes that
its high retention rates and multi-year policies better enable the Company to
evaluate its book of business, thus reducing uncertainty in establishing
reserves. Such reserves are related to various lines of business and will be
paid out over future periods.
 
  Management believes that environmental exposures are minimal as a result of
the types of risks the Company has insured. Historically, most commercial
accounts written post-date the coverages which afford clean-up costs and
Superfund responses. The Company currently has approximately $58 million
reserved for environmental and asbestos losses, of which $16 million consist
of case reserves, $19 million consist of loss adjustment expense reserves and
$23 million consist of IBNR reserves.
 
 
                                       5

 
 Reinsurance
 
  The Company limits the maximum net loss that can arise by large risks or
risks concentrated in areas of exposure by reinsuring with (ceding to) other
insurers or reinsurers. The Company's current net retention levels are
generally $2,000,000 per claim. The Company reinsures with companies that have
strong claims-paying ratings. The composition of its reinsurers has not
changed, and the Company has not experienced any uncollectible reinsurance
amounts or coverage disputes with its reinsurers, in more than ten years. The
Company has excess of loss treaties with Swiss Reinsurance Company, American
Reinsurance Company, Employers Reinsurance Company and General Reinsurance
Corporation.
 
LIFE INSURANCE
 
  Through The Cincinnati Life Insurance Company ("Cincinnati Life"), the
Company actively underwrites life insurance and accident and health insurance
in 29 states and has policies in force in 46 states and the District of
Columbia. Ordinary individual life insurance and annuity products constitute
the majority of Cincinnati Life's product lines. Cincinnati Life distributes
its products primarily through the Company's independent property and casualty
agencies. In addition, Cincinnati Life has established a worksite marketing
program and is developing relationships with independent life insurance agents
in markets outside of the property and casualty operations' geographic area.
Cincinnati Life generated $92.4 million of net premiums written in 1997 which
accounted for approximately 4% of the Company's total 1997 premium income.
 
FINANCIAL SERVICES
 
  CFC Investment Company ("CFC Investment") leases and finances vehicles and
equipment for the Company's agents and their clients and owns certain real
estate in the Cincinnati metropolitan area. CFC Investment's leasing and
financing activities create an additional source of income for the Company
while serving to improve the Company's relationships with its independent
agents and such independent agents' relationships with their customers.
Approximately half of the leasing customer base is comprised of independent
property and casualty agencies and a large portion of the Company's business
comes from agent referrals of their commercial insurance clients. Many
agencies lease or finance agency management systems that are funded through
Cincinnati Financial under incentive agreements requiring specified levels of
premium growth and profitability. Net after-tax earnings in 1997 rose to $2.2
million versus $1.2 million in 1996.
 
INVESTMENTS
 
  The Company's primary investment strategy is to achieve superior returns in
the form of capital appreciation and income, while maintaining sufficient
liquidity to meet both its immediate and long-term insurance obligations. The
Company implements this strategy through investing in equity securities and
medium-risk fixed maturity securities, which it believes have the potential
for ratings increases. The Company believes that investing in equity
securities offers it the opportunity to earn optimal returns through
increasing dividends and capital appreciation. The Company has utilized a
long-term, buy and hold strategy with respect to its equity portfolio,
resulting in an accumulation of significant unrealized gains on equity
investments. While the Company classifies all of its fixed maturity securities
as available for sale, the Company often holds such securities to maturity
absent a change in credit risk or the call of the securities by the issuer.
 
  Equity and fixed income securities accounted for 68% and 31%, respectively,
of the Company's total invested assets and 57% and 43%, respectively, of the
total invested assets of the Company's insurance subsidiaries, at December 31,
1997. Investment grade securities represented 58% of Cincinnati Financial's
fixed income portfolio and 69% of the fixed income portfolio of the Company's
insurance subsidiaries at December 31, 1997. Tax-exempt securities, which are
all held by the Company's insurance subsidiaries, represented 32% of the
Company's fixed income portfolio at December 31, 1997. Neither the Company nor
its subsidiaries invest in derivative instruments or real-estate related
securities. For further information concerning the Company's investment
strategy and portfolio, see "Management's Discussion and Analysis of Financial
Condition and Results of Operations" and Note 2 of Notes to Consolidated
Financial Statements incorporated by reference herein.

YEAR 2000 ISSUES
 
  The Company has continued system and network upgrades to address Year 2000
issues. Management believes that the few systems not yet Year 2000 compliant
will be technically compliant by mid-year 1999.

(1) Earnings for the year ended December 31, 1993 include a $13,845,000 credit
    for the cumulative effect of a change in the method of accounting for

    $8,641,000 related to the effect of the 1993 increase in income tax rates
    on deferred taxes recorded for various prior year items.
(2) The combined ratio is an industry measurement of the profitability of
    property and casualty insurance underwriting. This ratio is the sum of the
    ratio of incurred losses and loss adjustment expenses to net earned
    premiums (the "loss and LAE ratio") and the ratio of underwriting expenses
    incurred to net premiums written (the "underwriting expense ratio"). A
    combined ratio less than 100% generally indicates an underwriting profit;
    a combined ratio greater than 100% generally indicates an underwriting
    loss.
(3) Ratio represents statutory net property and casualty premiums written for
    the year divided by statutory policyholders' surplus at the end of the
    year attributable to the property and casualty business.
(4) For purposes of computing the ratio of earnings to fixed charges, earnings
    consist of net income before income tax expense (excluding interest costs
    capitalized) plus fixed charges to the extent that such charges are
    included in the determination of earnings. Fixed charges consist of
    interest costs (including interest costs capitalized) plus one-third of
    minimum rental payments under operating leases (estimated by Management to
    be the interest factor of such rentals).

                     MANAGEMENT DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
INTRODUCTION
 
  The following discussion is intended to supplement the data contained in the
Consolidated Financial Statements, and Notes thereto, of Cincinnati Financial
and its subsidiaries incorporated by reference herein.
 
  The Company has five subsidiaries. The lead property and casualty insurance
subsidiary, CIC, markets a broad range of business and personal policies in 27
states through an elite corps of 973 independent insurance agencies. Also
engaged in the property and casualty business are CCC, which works on a direct
billing basis, and Cincinnati Indemnity, which markets nonstandard policies
for preferred risk accounts. Cincinnati Life markets life, health and accident
policies through property and casualty agencies and independent life agencies.
CFC Investment complements the insurance subsidiaries with leasing, financing
and real estate services. Investment operations are the Company's primary
source of profits, with a total return strategy emphasizing investment in
fixed maturities securities as well as equity securities that contribute to
current earnings through dividend increases and add to net worth through long-
term appreciation.
 
  The following discussion and related Consolidated Financial Statements, and
Notes thereto, incorporated by reference herein contain certain forward-
looking statements that involve potential risks and uncertainties. The
Company's future results could differ materially from those discussed. Factors
that could cause or contribute to such differences include, but are not
limited to: unusually high levels of catastrophe losses due to changes in
weather patterns or other natural causes; changes in insurance regulations or
legislation that place the Company at a disadvantage in the marketplace;
recession or other economic conditions resulting in lower demand for insurance
products; sustained decline in overall stock market values negatively
impacting the Company's equity portfolio and the ability to generate
investment income; and, the potential inability of the Company and/or the
independent agents with which it works to complete the necessary information
system changes required to handle Year 2000 issues. Readers are cautioned that
the Company undertakes no obligation to review or update the forward-looking
statements included in this material.
 
RESULTS OF OPERATION
 
 Overview of Results
 
  Primarily as a result of continued market penetration and entry into new
states, the Company's revenues have increased at a compound annual rate of
8.3%, reaching $1.942 billion in 1997, with property/casualty net written
premiums growing at a compound annual rate of 7.7% to $1.472 billion over the
past five years. In the same five-year period, total net income, including
realized capital gains, grew at a compound annual rate of 11.8% to $299.4
million from $216.0 million while net operating income increased at a compound
annual rate of 11.5% to $254.4 million from $182.5 million in 1993. Book value
grew at a 22.2% compound annual rate over the same period.
 
  A number of factors, including the Company's strong reputation among
independent insurance agencies and Management's belief that the Company can
achieve additional market penetration in states in which it currently
operates, have led Management to target $2 billion in direct written premiums
during the year 2000, up from $1.621 billion in 1997. At the same time, the
Company seeks to generate an underwriting profit and maximize annual growth in
investment income.
 
  The following discusses and analyzes results for the three-year period
ending December 31, 1997 and provides insight into Management's strategic
direction for the Company.

  The Company's financial results for the three years ending December 31, 1997
reflect steady growth in new insurance business and high retention of renewal
business quoted on behalf of the Company's independent insurance agents,
offset by competitive property and casualty pricing. In addition, 1997 marked
a return to a more normal level of catastrophe losses from the unusually high
1996 level. Results for 1997 also reflect the Company's consistent
underwriting philosophy and strategy--maintaining high underwriting standards
by carefully evaluating individual risks, reviewing agency performance and
controlling overall expenses.
 
  Net operating income for 1997 rose substantially over the prior year. The
Company generated 6.5% growth in pre-tax investment income and an underwriting
profit versus an underwriting loss in 1996, primarily due to lower catastrophe
losses. In 1996, net operating income declined 7% because of the catastrophe
losses, while pre-tax investment income rose 9.1%. The contribution from net
realized capital gains after-tax rose in both years primarily due to the sale
of equity securities.

 Premiums
 
  While premium growth rates have declined in 1997 and 1996, the Company's
property and casualty group continued to increase net written premiums at
rates well above estimated industry growth rates. In 1997 and 1996, the
primary source of growth was personal lines insurance, for which net written
premiums advanced 12.4% in 1997 (9.4% in 1996), while commercial lines
insurance growth was 3.6% (5.6% in 1996).
 
  During 1997 and 1996, the commercial insurance market experienced intense
price competition, most notably in workers' compensation where market-share
competition and mandated rate reductions in some states led to renewal account
discounts of as much as a third from the previous year's premium. The Company
is committed to prudent underwriting standards and emphasizing account
profitability. The emphasis on profitability contributed to the 53.2% pure
loss ratio for the commercial lines area, in line with the 54.8% reported in
1996.
 
  As a result of market factors, direct written workers' compensation premiums
in 1997 declined 6% and growth in other commercial insurance lines was
limited. Management believes these competitive forces will continue for at
least the next six to twelve months. To help offset these pressures, the
Company is emphasizing personal lines insurance, entering new states to expand
market opportunities, pursuing a marketing strategy that permits field
representatives to spend more time assisting the independent insurance agents
and expanding its life insurance operations.
 
  The Company sees heightened interest from independent insurance agents in
writing personal lines insurance as a means of buffering the price competition
in the commercial sector and stabilizing their revenue. The Company is taking
advantage of this trend by encouraging independent agents to move to the
Company their proven, profitable business. Agents who are streamlining
operations by reducing the number of carriers they represent have been rolling
over entire books of business to the Company.
 
  Management believes Cincinnati Financial can achieve additional market
penetration by leveraging its strong relationships with independent agencies
and entering new states. The Company also can take advantage
 
                                      11

 
of key competitive advantages of Cincinnati Financial's insurance products,
for example three- and five-year policies for many types of insurance
coverage.
 
  At year-end 1997, approximately 98% of the Company's property and casualty
premium volume was in states in which the Company has had a presence since
1994 or earlier. Over the past three years, the Company has added nine
marketing representatives in several established states, restructuring
territories so that each representative has fewer agencies to serve. This has
allowed field representatives to appoint additional agencies and, more
importantly, spend more time with each agent. During 1998, Management
anticipates adding two marketing territories in existing regions.
 
  Entry into new states also has been a source of premium growth. During 1997,
the states the Company entered between 1994 and 1997 contributed more than $28
million of property and casualty premium volume. An example of these
successful new market entries is Minnesota, where premium volume reached $11.7
million in 1997, up from $800,000 in 1994. During 1996 and 1997, the Company
began marketing commercial lines in North Dakota and added personal lines in
Arkansas, Maryland, Minnesota, North Dakota, Pennsylvania and Vermont. During
1998, Management anticipates beginning to market insurance products in Montana
and in two planned upstate New York territories. Five western states currently
are being researched with the intention of selecting one or two additional
states in which to seek approval during 1998 to market the Company's products
in 1999. The Company's criteria for entry into new states include a favorable
regulatory climate.
 
 Expenses
 
  The Company recorded a $24.8 million underwriting profit in 1997 compared
with an $45.0 million underwriting loss in 1996 and a $1.4 million
underwriting profit in 1995. The 1997 underwriting profit, reflected by a
combined ratio of 97.7%, was primarily the result of a more normal level of
catastrophe losses contributing to a seven point reduction in the loss and
loss adjustment expense ratio compared with 1996. The return to a more normal
level of catastrophe losses also helped offset a one and seven-tenths point
increase in the expense ratio. The underwriting loss in 1996, reflected by a
combined ratio of 103.0%, was the result of the higher catastrophe losses, as
well as a half percentage point increase in the expense ratio over 1995.
 
  The expense ratio increased in both years as the Company raised spending on
staff and costs associated with upgrading technology and facilities to
accommodate anticipated growth in premium volume while making computer systems
Year 2000 compliant. Because the Company issues three- and five-year policies,
Management believes that Year 2000 compliance issues have been initiated for
most of the computer systems. Many systems are already Year 2000 compliant;
most other programs will be compliant by year-end 1998, with the balance
completed during 1999. Management believes this goal will be attained. The
Company's largest risk lies with Year 2000 compliance by its independent
agencies, which handle most of the customer billing and collections. In
response to this concern, the Company is proactively contacting agents
regarding this issue and will be monitoring each agency's actions closely.
Adding to expenses in 1997 were higher profit-sharing commissions to many of
the Company's independent insurance agents, due to the overall profitability
of the business they wrote.
 
  In 1997, catastrophe losses accounted for 1.8% of the combined ratio, more
closely in line with the Company's historic results and in contrast to the
unusually high 4.7% from ten large storms in 1996. In 1995, catastrophe losses
accounted for 2.1% of the combined ratio. Due to the nature of catastrophic
events, Management is unable to predict accurately the frequency or potential
cost of such occurrences in the future; however, the Company has continued not
to market property and casualty insurance in California, not to write flood
insurance, to review exposure to huge disasters and reduce coverage in certain
coastal regions in an effort to control such catastrophe losses. For property
catastrophes, the Company retains the first $25 million of losses and is
reinsured to cover 95% of the losses from $25 million up to $200 million.
 
  As discussed in the Notes to the Consolidated Financial Statements
incorporated by reference herein, the Company's insurance reserve liabilities
are estimated by Management based upon Company experience data. The Company
consistently has established property and casualty insurance reserves,
including adjustments of
 
                                      12

 
estimates, using information from internal analysis and review by external
actuaries. Though uncertainty always exists as to the adequacy of established
reserves, Management believes this uncertainty is less than it otherwise would
be, due to the stability of the Company's book of business. Such reserves are
related to various lines of business and will be paid out over future periods.
 
  Reserves for environmental claims have been reviewed and the Company
believes that the reserves are adequate. Environmental exposures are minimal
as a result of the types of risks the Company has insured in the past.
Historically, most commercial accounts written post-date the coverages which
afford clean-up costs and Superfund responses.
 
 Life and Accident and Health
 
  The Company's life insurance subsidiary, Cincinnati Life, had total net
premium income for 1997 of $62.9 million, up from $56.4 million in 1996 and
$50.9 million in 1995. Life insurance premiums were $54.7 million, $48.7
million and $43.6 million, respectively. Cincinnati Life contributed 10% of
the Company's operating income in 1997, 1996 and 1995.
 
  During 1997, the Company hired a new president for Cincinnati Life. Under
his direction, Cincinnati Life is expanding worksite marketing activities,
introducing a competitive new life insurance product series and researching
opportunities to sell life insurance in states in which the Company does not
have property and casualty agency representation. The initiatives, which were
undertaken in the second half of 1997, had little impact on results for the
year. Management believes, however, that opportunities exist to increase
Cincinnati Life's contribution to total operating income through expanded life
insurance sales.
 
 Investment Income and Investments
 
  Investment income rose 6.5% to $348.6 million in 1997 and increased 9.1% to
$327.3 million in 1996. The slower growth rate in 1997 reflected the amount of
fixed maturities investments called early and the generally lower interest
rate environment. The increases were primarily the result of investing the
cash flows from operating activities and dividend increases from equity
securities in the investment portfolio. In 1997, 34 of the 62 common stocks in
the Company's investment portfolio increased dividends during the year, adding
more than $8.1 million to future annualized investment earnings.
 
  The Company's primary investment strategy is to maintain liquidity to meet
both immediate and long-term insurance obligations through the purchase and
maintenance of medium-risk, fixed maturity and equity securities, while
earning optimal returns on the equity portfolio through higher dividends and
capital appreciation. The Company's investment decisions on an individual
insurance company basis are influenced by insurance statutory requirements
designed to protect policyholders from investment risk. Cash generated from
insurance operations is invested almost entirely in corporate, municipal,
public utility and other fixed maturity securities or equity securities. Such
securities are evaluated prior to purchase based on yield and risk.
 
  Investments in common stocks have emphasized securities with an annual
dividend yield of at least 2%-3% and annual dividend increases. The Company's
portfolio of equity investments had an average dividend yield to cost of 7.8%
at December 31, 1997. Management's strategy in equity investments includes
identifying approximately ten to twelve companies, for the core of the
investment portfolio, in which the Company can accumulate 10%-20% of their
common stock.
 
 Interest and Income Taxes
 
  The Company's income tax expense was $95.2 million, $58.7 million and $67.8
million for 1997, 1996 and 1995, respectively, while the effective tax rate
was 24.12%, 20.77% and 22.98%, for the same periods. The higher tax rate in
1997 primarily was due to the strong underwriting profit recorded for the year
and higher capital gains. The lower rate in 1996 was partially the result of a
higher percentage of net income earned from tax-exempt interest on state,
municipal and political subdivision fixed maturities and dividends received on
equity investments. The Company incurred no additional alternative minimum tax
expenses for 1997, 1996 and 1995.

 Cash Flow
 
  Over the past three years, operating cash flows have been sufficient to meet
operating needs and provide for financing needs and increased investment.
Management expects operating cash flow will continue to be the Company's
primary source of funds because no substantial changes are anticipated in the
Company's mix of business nor are there plans to reduce protection by ceded
reinsurance agreements with financially stable reinsurance companies. Further,
the Company has no significant exposure to assumed reinsurance. Assumed
reinsurance comprised no more than 3% of gross premiums in each of the last
three years.
 
  The change in net cash used in investing activities reflected a steady
increase over the three years in calls of fixed maturity investments, offset
in 1997 by increased purchases of fixed maturities and equity securities. Cash
flows used in net purchases of fixed maturity and equity securities,
respectively, amounted to $122.6 million and $134.1 million in 1997, $98.0
million and $95.4 million in 1996, and $309.7 million and $114.9 million in
1995.
 
  Over the three-year period, the primary increases in net cash used for
financing activities were for the payment of cash dividends and the purchase
of treasury shares.
 
  Notes Payable--Increases in notes payable, primarily short-term debt used to
enhance liquidity, were reduced from $91.9 million in 1995 to $41.1 million in
1996 to $18.5 million in 1997. Management used short-term debt for cash
management and other purposes.
 
 
  Dividends--The Company has increased cash dividends to shareholders for 37
consecutive years and, periodically, the Board of Directors authorizes stock
dividends or splits. In February 1997, the Company's Board voted to increase
the regular quarterly dividend by four cents to an indicated annual rate of
$1.64 per share. On February 7, 1998, the Board authorized a 12.2% increase,
raising the regular quarterly dividend by five cents to an indicated annual
rate of $1.84. On April 4, 1998, the Board declared a three-for-one stock
split to be distributed on May 15, 1998, to shareholders of record as of April
24, 1998.
 
 
  Since 1987, the Company's Board of Directors has authorized four additional
stock splits or stock dividends: a 5% stock dividend in 1996; a 5% stock
dividend in 1995; a three-for-one stock split in 1992; and, a 5% stock
dividend in 1987. After the stock split in 1998, a shareholder who purchased
one CIC share before 1957 would own 1,947 Cincinnati Financial shares, if all
shares from accrued stock dividends and splits were held. The Company's policy
for the past ten years has been to reinvest approximately 70% of net income in
future growth and to distribute remaining income as dividends. The ability of
the Company to continue paying cash dividends is subject to such factors as
the Board of Directors may deem relevant.
 
                                      14

 
FINANCIAL CONDITION
 
 Assets
 
  Cash and marketable securities of $8.831 billion make up 93.0% of the
Company's $9.493 billion of assets; this compares with 90.3% in 1996 and 90.2%
in 1995. The Company has only minor investments in real estate and mortgages,
which are typically illiquid. At December 31, 1997, the Company's portfolio of
fixed maturity securities had an average yield-to-cost of 8.4% and an average
maturity of 12 years. For the insurance companies' purposes, strong emphasis
has been placed on purchasing current income-producing securities and
maintaining such securities as long as they continue to meet the Company's
yield and risk criteria. Historically, municipal bonds have been attractive
due to their tax-exempt feature. Essential service (e.g., schools, sewer,
water, etc.) bonds issued by municipalities are prevalent in this area. Many
of these bonds are not rated due to the small size of their offerings.
 
  At year-end 1997 and 1996, investments totaling approximately $836 million
and $729 million ($797 million and $706 million at cost) of the Company's
$8.797 billion and $6.344 billion investment portfolio related to securities
rated non-investment grade or not rated by Moody's Investors Service or
Standard & Poor's. Such investments, which tend to have higher yields,
historically have benefited the Company's results of operations. Further, many
have been upgraded to investment grade while owned by the Company.
 
  Because of alternative minimum tax considerations, the Company uses a blend
of tax-exempt and taxable fixed maturity securities. Tax exempt bonds
comprised 10% of invested assets as of December 31, 1997, compared with 14% at
year-end 1996 and 16% at year-end 1995. Additional information regarding the
composition of investments, together with maturity data regarding investments
in fixed maturities, is included in the Notes to Consolidated Financial
Statements incorporated by reference herein.
 
 Market Risk
 
  The Company could incur losses due to adverse changes in market rates and
prices. The Company's primary market risk exposures are to changes in price
for equity securities and changes in interest rates and credit ratings for
fixed maturity securities. The Company could alter the existing investment
portfolios or change the character of future investments to manage exposure to
market risk. The Company, with the Board of Directors, administers and
oversees investment risk through the Investment Committee, which provides
executive oversight of investment activities. The Company has specific
investment guidelines and policies that define the overall framework used
daily by investment portfolio managers to limit the Company's exposure to
market risk.
 
 Liabilities and Shareholders' Equity
 
  At December 31, 1997, long- and short-term debt were 4%, insurance reserves
were 25% and total shareholders' equity was 50% of total assets, with
remaining liabilities consisting of unearned premiums, deferred income taxes
and other liabilities.
 
  Debt--Total long- and short-term debt was less than 5% of total assets at
year-end 1997 and 1996. At December 31, 1997 and 1996, long-term debt
consisted of $58.4 million and $79.8 million, respectively, of convertible
debentures. Short-term debt is used to provide working capital as discussed
above.
 
  Equity--Shareholders' equity has continued to grow as a percentage of total
assets, reaching 50% for 1997 from 45% for 1996 and 44% for 1995, due to
retained earnings and unrealized appreciation of investments. Statutory risk-
based capital requirements became effective for life insurance companies in
1993 and for property and casualty companies in 1994. The Company's capital
has been well above required amounts in each year since those effective dates.

  As a long-term investor, the Company has followed a buy-and-hold strategy
for more than 38 years. A significant amount of unrealized appreciation on
equity investments has been generated as a result of this policy. Unrealized
appreciation on equity investments, before deferred income taxes, was $4.273
billion as of December 31, 1997 and constituted 49% of the total investment
portfolio; 71% of the equities investment portfolio; and, after deferred
income taxes, 59% of total shareholders' equity. Such unrealized appreciation,
before deferred income taxes, amounted to $2.203 billion and $1.618 billion,
at year-end 1996 and 1995, respectively.
 
  On November 22, 1996, the Board of Directors authorized the repurchase of up
to three million of the Company's outstanding shares as Management deemed
appropriate over an unspecified period of time. As of December 31, 1997, the
Company had repurchased 934,041 shares, at an accumulated cost of $68.1
million.

                         DESCRIPTION OF THE DEBENTURES
 
  The Debentures are to be issued under an Indenture (the "Indenture") between
the Company and The First National Bank of Chicago, as Trustee (the
"Trustee"), a copy of which is filed as an exhibit to the Registration
Statement of which this Prospectus is a part. The following summaries of the
material provisions of the Indenture and the Debentures do not purport to be
complete and are subject to, and are qualified in their entirety by reference
to, all of the provisions of the Indenture, including the definitions therein
of certain terms, and such Debentures. Wherever particular articles, sections
or defined terms of an Indenture are referred to, it is intended that such
articles, sections or defined terms shall be incorporated herein by reference,
and the statement in connection with which such reference is made is qualified
in its entirety by such reference.
 
GENERAL
 
  The Debentures are limited to $350,000,000 aggregate principal amount and
will mature on         , 2028.
 
  The Debentures will be issued only in fully registered form without coupons
in denominations of $1,000 and any integral multiple thereof. No service
charge will be made for any registration of transfer or exchange of Offered
Debentures, but the Company may require payment of a sum sufficient to cover
any tax or other governmental charge payable in connection therewith.
 
  The Debentures will bear interest at the rate per annum set forth on the
cover page of this Prospectus from          , 1998, or from the most recent
interest payment date to which interest has been paid or provided for, payable
semiannually in arrears on         and           of each year, beginning on
        , 1998, to the persons in whose names the Debentures are registered at
the close of business on the next preceding       or      , as the case may
be.
 
  The Debentures are not redeemable prior to maturity.
 
BOOK-ENTRY, DELIVERY AND FORM
 
  The Debentures will be issued in the form of fully registered Global
Securities. The Global Securities will be deposited with, or on behalf of, The
Depository Trust Company, New York, New York (the "Depository' and registered
in the name of the Depository's nominee.
 
  Except as set forth below, the Global Securities may be transferred, in
whole and not in part, only to another nominee of the Depository or to a
successor of the Depository or its nominee.
 
  The Depository has advised the Company and the Underwriters as follows: It
is a limited-purpose trust company which was created to hold securities for
its participating organizations (the "Participants") and to facilitate the
clearance and settlement of transactions in such securities between
Participants through electronic book-entry changes in accounts of its
Participants. Participants include securities brokers and dealers (including
the Underwriters), banks, trust companies, clearing corporations and certain
other organizations. Access to the Depository's book-entry system is also
available to others, such as banks, brokers, dealers and trust companies that
clear through or maintain a custodial relationship with a Participant, either
directly or indirectly ("indirect participants"). Persons who are not
Participants may beneficially own securities held by the Depository only
through Participants or indirect participants.
 
  The Depository has also advised that pursuant to procedures established by
it (i) upon the issuance by the Company of the Debentures, the Depository will
credit the accounts of Participants designated by the Underwriters with the
principal amount of the Debentures purchased by the Underwriters, and (ii)
ownership of beneficial interests in the Global Securities will be shown on,
and the transfer of that ownership will be effected only through, records
maintained by the Depository (with respect to Participants' interests), the
Participants and the indirect participants. The laws of some states require
that certain persons take physical delivery in definitive form of securities
which they own. Consequently, the ability to transfer beneficial interests in
the Global Securities is limited to such extent.
 
                                      17

 
  So long as a nominee of the Depository is the registered owner of the Global
Securities, such nominee will be considered the sole owner or holder of the
Debentures for all purposes under the Indenture. Except as provided below,
owners of beneficial interests in the Global Securities will not be entitled
to have Debentures registered in their names, will not receive or be entitled
to receive physical delivery of Debentures in definitive form and will not be
considered the owners or holders thereof under the Indenture.
 
  Neither the Company, the Trustee, any Paying Agent nor the Registrar will
have any responsibility or liability for any aspect of the records relating to
or payments made on account of beneficial ownership interests in the Global
Securities, or for maintaining, supervising or reviewing any records relating
to such beneficial ownership interests.
 
  Principal and interest payments on the Global Securities registered in the
name of the Depository's nominee will be made by the Company through the
Paying Agent to the Depository's nominee as the registered owner of the Global
Securities. Under the terms of the Indenture, the Company and the Trustee will
treat the persons in whose names the Debentures are registered as the owners
of such Debentures for the purpose of receiving payments of principal and
interest on such Debentures and for all other purposes whatsoever. Therefore,
neither the Company, the Trustee nor any Paying Agent has any direct
responsibility or liability for the payment of principal or interest on the
Debentures to owners of beneficial interests in the Global Securities. The
Depository has advised the Company and the Trustee that its present practice
is, upon receipt of any payment of principal or interest, to credit
immediately the accounts of the Participants with payment in amounts
proportionate to their respective holdings in principal amount of beneficial
interests in the Global Securities as shown on the records of the Depository.
Payments by Participants and indirect participants to owners of beneficial
interests in the Global Securities will be governed by standing instructions
and customary practices, as is now the case with securities held for the
accounts of customers in bearer form or in "street name" and will be the
responsibility of such Participants or indirect participants.
 
  If the Depository is at any time unwilling or unable to continue as
depository and a successor depository is not appointed by the Company within
90 days, the Company will issue Debentures in definitive form in exchange for
the Global Securities. In addition, the Company may at any time determine not
to have the Debentures represented by Global Securities and, in such event,
will issue Debentures in definitive form in exchange for the Global
Securities. In either instance, an owner of a beneficial interest in the
Global Securities will be entitled to have Debentures equal in principal
amount to such beneficial interest registered in its name and will be entitled
to physical delivery of such Debentures in definitive form. Debentures so
issued in definitive form will be issued in denominations of $1,000 and
integral multiples thereof and will be issued in registered form only, without
coupons.
 
SAME-DAY SETTLEMENT AND PAYMENT
 
  Settlement for the Debentures will be made by the Underwriters in
immediately available funds. All payments of principal and interest will be
made by the Company in immediately available funds.
 
  Secondary trading in long-term notes and debentures of corporate issuers is
generally settled in clearing-house or next-day funds. In contrast, the
Debentures will trade in the Depository's Same-Day Funds Settlement System
until maturity, and secondary market trading activity in the Debentures will
therefore be required by the Depository to settle in immediately available
funds.
 
COVENANTS
 
 Limitation on Liens of Stock of Subsidiaries
 
  The Indenture prohibits the Company and its Subsidiaries from directly or
indirectly creating, assuming, incurring or permitting to exist any
Indebtedness secured by any lien on the capital stock of any Designated
Subsidiary unless the Debentures (and, if the Company so elects, any other
Indebtedness of the Company that is
 
                                      18

 
not subordinate to the Debentures and with respect to which the governing
instruments require, or pursuant to which the Company is otherwise obligated,
to provide such security) shall be secured equally and ratably with such
Indebtedness for at least the time period such other Indebtedness is so
secured.
 
  The term "Designated Subsidiary" means any present or future consolidated
subsidiary of the Company, the consolidated net worth of which constitutes at
least 10% of the consolidated net worth of the Company. As of March 31, 1998,
the Company's Designated Subsidiaries were CIC and Cincinnati Life.
 
  "Indebtedness" is defined in the Indenture as the principal of and any
premium and interest due on indebtedness of a Person, whether outstanding on
the date of such Indenture or thereafter created, incurred or assumed, which
is (a) indebtedness for money borrowed, and (b) any amendments, renewals,
extensions, modifications and refunds of any such indebtedness. For the
purposes of this definition, "indebtedness for money borrowed" means (i) any
obligation of, or any obligation guaranteed by, such Person for the repayment
of borrowed money, whether or not evidenced by bonds, debentures, notes or
other written instruments, (ii) any obligation of, or any such obligation
guaranteed by, such Person evidenced by bonds, debentures, notes or similar
written instruments, including obligations assumed or incurred in connection
with the acquisition of property, assets or businesses (provided, however,
that the deferred purchase price of any other business or property or assets
shall not be considered Indebtedness if the purchase price thereof is payable
in full within 90 days from the date on which such indebtedness was created),
and (iii) any obligations of such Person as lessee under leases required to be
capitalized on the balance sheet of the lessee under generally accepted
accounting principles and leases of property or assets made as part of any
sale and lease-back transaction to which such Person is a party. For purposes
of this covenant only, Indebtedness also includes any obligation of, or any
obligation guaranteed by, any Person for the payment of amounts due under a
swap agreement or similar instrument or agreement, or under a foreign currency
hedge exchange or similar instrument or agreement.
 
 Limitations on Disposition of Stock of Designated Subsidiaries
 
  The Indenture also provides that so long as any Debentures are outstanding
and except in a transaction otherwise governed by such Indenture, the Company
may not issue, sell, transfer or otherwise dispose of any shares of,
securities convertible into, or warrants, rights or options to subscribe for
or purchase shares of, capital stock (other than preferred stock having no
voting rights of any kind) of any Designated Subsidiary, and will not permit
any Designated Subsidiary to issue (other than to the Company) any shares
(other than director's qualifying shares) of, or securities convertible into,
or warrants, rights or options to subscribe for or purchase shares of, capital
stock (other than preferred stock having no voting rights of any kind) of any
Designated Subsidiary, if, after giving effect to any such transaction and the
issuances of the maximum number of shares issuable upon the conversion or
exercise of all such convertible securities, warrants, rights or options, the
Company would own, directly or indirectly, less than 80% of the shares of such
Designated Subsidiary (other than preferred stock having no voting rights of
any kind); provided, however, that (i) any issuance, sale, transfer or other
disposition permitted by the Company may only be made for at least a fair
market value consideration as determined by the Board of Directors pursuant to
a Board Resolution adopted in good faith and (ii) the foregoing shall not
prohibit any such issuance or disposition of securities if required by any law
or any regulation or order of any governmental or insurance regulatory
authority. Notwithstanding the foregoing, (i) the Company may merge or
consolidate any Designated Subsidiary into or with another direct wholly owned
Subsidiary of the Company and (ii) the Company may, subject to the provisions
set forth in "Consolidation, Merger and Sale of Assets" below, sell, transfer
or otherwise dispose of the entire capital stock of any Designated Subsidiary
at one time for at least a fair market value consideration as determined by
the Board of Directors pursuant to a Board Resolution adopted in good faith.
 
CONSOLIDATION, MERGER AND SALE OF ASSETS
 
  The Indenture provides that the Company may, without the consent of the
Holders, consolidate with, or sell, lease or convey all or substantially all
of its assets to, or merge into any other corporation, provided that in any
such case, (i) the successor corporation shall be a corporation organized and
existing under the laws of the
 
                                      19

 
United States or a State thereof, and such corporation shall expressly assume
the due and punctual payment of the principal of (and premium, if any) and
interest on all the applicable Debentures, according to their tenor, and the
due and punctual performance and observance of all the covenants and
conditions of the Indenture to be performed by the Company by supplemental
indenture satisfactory to the applicable Trustee, executed and delivered to
the applicable Trustee by such corporation; and (ii) immediately after giving
effect to such transaction, no Default shall have occurred and be continuing.
 
  Other than the covenants described above, the Indenture does not contain any
covenants or other provisions designed to afford holders of the Debentures
protection in the event of a takeover, recapitalization or a highly leveraged
transaction involving the Company.
 
MODIFICATION OF THE INDENTURE
 
  With the consent of the holders ("Holders") of more than 50% in aggregate
principal amount of the Debentures then outstanding under the Indenture,
waivers, modifications and alterations of the terms of the Indenture may be
made which affect the rights of the Holders of the Debentures, except that no
such modification or alteration may be made which will (a) extend the time or
terms of payment of the principal at maturity of, or the interest on, any of
the Debentures, or reduce principal or premium or the rate of interest,
without the consent of the Holder thereof, or (b) without the consent of all
of the Holders of the Debentures then outstanding, reduce the percentage of
the Debentures the Holders of which are required to consent (i) to any such
supplemental indenture, (ii) to rescind and annul a declaration that the
Debentures are due and payable as a result of the occurrence of an Event of
Default, (iii) to waive any past Event of Default under the Indenture and its
consequences, and (iv) to waive compliance with certain other provisions
contained in the Indenture. In addition, as indicated under "Events of
Default" below, Holders of more than 50% in aggregate principal amount of the
Debentures then outstanding may waive past Events of Default in certain
circumstances and may direct the Trustee in enforcement of remedies. The
Company and the Trustee may, without the consent of any Holders, modify and
supplement the Indenture (i) to evidence the succession of another corporation
to the Company under the Indenture; (ii) to evidence and provide for the
replacement of the Trustee; (iii) with the Company's concurrence, to add to
the covenants of the Company for the benefit of the Holders; (iv) to modify
the Indenture to permit the qualification of any supplemental indenture under
the Trust Indenture Act of 1939; and (v) for certain other purposes.
 
DEFEASANCE, SATISFACTION AND DISCHARGE TO MATURITY OR REDEMPTION
 
  Defeasance. If the Company shall deposit with the Trustee, in trust, at or
before maturity or redemption, lawful money or direct obligations of the
United States or obligations the principal of and interest on which are
guaranteed by the United States (or by such other government) in such amounts
and maturing at such times that the proceeds of such obligations to be
received upon the respective maturities and interest payment dates of such
obligations will provide funds sufficient, in the opinion of a nationally-
recognized firm of independent public accountants, to pay when due the
principal (and premium, if any) and interest to maturity or to the redemption
date, as the case may be, with respect to the Debentures then outstanding,
then the Company may cease to comply with the terms of the Indenture,
including the restrictive covenants described under "Limitation on Liens of
Stock of Subsidiaries" and "Limitations on Disposition of Stock of Designated
Subsidiaries" above and the Events of Default described in clauses (c) and (d)
under "Events of Default" below, except for (i) the Company's obligation to
duly and punctually pay the principal of (and premium, if any) and interest on
the Debentures if the Debentures are not paid from the money or securities
held by the Trustee, and (ii) the Events of Default described in clauses (a),
(b), (c) and (d) under "Events of Default" below, and (iii) certain other
provisions of the Indenture including, among others, those relating to
registration, transfer and exchange, lost or stolen securities and maintenance
of place of payment. Defeasance of the Debentures is subject to the
satisfaction of certain specified conditions, including, among others, (i) the
absence of an Event of Default at the date of the deposit, and (ii) the
perfection of the Holders' security interest in such deposit.
 
                                      20

 
  Satisfaction and Discharge. Upon the deposit of money or securities
contemplated above and the satisfaction of certain conditions, the Company may
also cease to comply with its obligation duly and punctually to pay the
principal of (and premium, if any) and interest on the Debentures, or with any
Events of Default with respect thereto, and thereafter the Holders of the
Debentures shall be entitled only to payment out of the money or securities
deposited with the Trustee. Such conditions include, among others, except in
certain limited circumstances involving a deposit made within one year of
maturity or redemption, (i) the absence of an Event of Default at the date of
deposit or on the 91st day thereafter, (ii) the delivery to the Trustee by the
Company of an opinion of nationally-recognized tax counsel, or receipt by the
Company from, or publication of a ruling by the United States Internal Revenue
Service, to the effect that Holders of the Debentures will not recognize
income, gain or loss for Federal income tax purposes as a result of such
deposit and discharge and will be subject to Federal income tax on the same
amounts and in the same manner and at the same times as would have been the
case if such deposit and discharge had not occurred, and (iii) that such
satisfaction and discharge will not result in the delisting of the Debentures
from any nationally-recognized exchange on which they are listed.
 
  Federal Income Tax Consequences. Under current Federal income tax law, the
deposit and defeasance described above under "Defeasance" will not result in a
taxable event to any Holder of Debentures or otherwise affect the Federal
income tax consequences of an investment in the Debentures.
 
  The Federal income tax treatment of the deposit and discharge described
above under "Satisfaction and Discharge" is not clear. A deposit and discharge
may be treated as a taxable exchange of such Debentures for beneficial
interests in the trust consisting of the deposited money or securities. In
that event, a Holder of Debentures may be required to recognize gain or loss
equal to the difference between the Holder's adjusted basis for the Debentures
and the amount realized in such exchange (which generally will be the fair
market value of the Holder's beneficial interest in such trust). Thereafter,
such Holder may be required to include in income a share of the income, gain
and loss of the trust. As described above, it is generally a condition to such
a deposit and discharge to obtain an opinion of tax counsel, or receipt by the
Company from, or publication of a ruling by the United States Internal Revenue
Service, to the effect that such deposit and discharge will not alter the
Holders' tax consequences that would have been applicable in the absence of
the deposit and discharge. Purchasers of the Debentures should consult their
own advisors with respect to the tax consequences to them of such deposit and
discharge, including the applicability and effect of tax laws other than
Federal income tax law.
 
EVENTS OF DEFAULT
 
  With respect to the Debentures, an Event of Default is defined in the
Indenture as being: (a) default for 30 days in payment of any interest on the
Debentures; (b) failure to pay principal or premium with respect to the
Debentures, if any, when due; (c) failure to observe or perform any other
covenant in the Indenture or Debentures (other than a covenant or warranty, a
default in whose performance or whose breach is specifically dealt with in the
section of the Indenture governing Events of Default), if such failure
continues for 30 days after written notice by the Trustee or the Holders of at
least 25% in aggregate principal amount of the Debentures then outstanding;
(d) uncured or unwaived failure to pay principal of or interest on any other
obligation for borrowed money of the Company beyond any period of grace with
respect thereto if (i) the aggregate principal amount of any such obligation
is in excess of $50,000,000 and (ii) the default in such payment is not being
contested by the Company in good faith and by appropriate proceedings; or (e)
certain events of bankruptcy, insolvency, receivership or reorganization. The
Trustee or the Holders of 25% in aggregate principal amount of the outstanding
Debentures may declare the Debentures immediately due and payable upon the
occurrence of any Event of Default (after expiration of any applicable grace
period); in certain cases, the Holders of a majority in principal amount of
the Debentures then outstanding may waive any past default and its
consequences, except a default in the payment of principal, premium, if any,
or interest (including sinking fund payments).
 
  Each Indenture provides that the Trustee shall, within 90 days after the
occurrence of a default with respect the Debentures which is continuing, give
to the Holders of the Debentures notice of all uncured defaults known to it
(the term default to include the events specified above without grace
periods); provided that, except in the
 
                                      21

 
case of default in the payment of principal (or premium, if any) or interest
on any of the Debentures, the Trustee shall be protected in withholding such
notice if it in good faith determines that the withholding notice is in the
interest of the Debenture Holders.
 
  Subject to the provisions of the Indenture relating to the duties of the
Trustee in case an Event of Default with respect to the Debentures shall occur
and be continuing, the Indenture provides that the Trustee shall be under no
obligation to exercise any of its rights or powers under the Indenture at the
request, order or direction of any of the Holders of Debentures outstanding
unless such Holders shall have offered to the Trustee reasonable indemnity.
The right of a Holder to institute a proceeding with respect to the Indenture
is subject to certain conditions precedent including notice and indemnity to
the Trustee, but the Holder has a right to receipt of principal, premium, if
any, and interest (subject to certain limitations with respect to defaulted
interest) on their due dates or to institute suit for the enforcement thereof.
 
  So long as the Debentures remain outstanding the Company will be required to
furnish annually to the Trustee an Officers' Certificate stating whether, to
the best of the knowledge of the signers, the Company is in default under any
of the provisions of the Indenture, and specifying all such defaults, and the
nature thereof, of which they have knowledge. The Company will also be
required to furnish to the Trustee copies of certain reports filed by the
Company with the Commission.
 
  The Holders of a majority in principal amount of the Debentures outstanding
will have the right to direct the time, method and place for conducting any
proceeding for any remedy available to the Trustee, or exercising any power or
trust conferred on the Trustee, provided that such direction shall be in
accordance with law and the provisions of the Indenture, provided that the
Trustee may decline to follow any such direction if the Trustee shall
determine on the advice of counsel that the proceeding may not be lawfully
taken or would be materially or unjustly prejudicial to Holders not joining in
such direction. The Trustee will be under no obligation to act in accordance
with such direction unless such Holders shall have offered the Trustee
reasonable security or indemnity against costs, expenses and liabilities which
may be incurred thereby.
 
INFORMATION CONCERNING THE TRUSTEE
 
  The Company may from time to time borrow from the Trustee or an affiliate
thereof or otherwise maintain other banking transactions with the Trustee or
an affiliate thereof in the ordinary course of business.
 
  Under the Indenture, the Trustee is required to transmit annual reports to
all Holders regarding its eligibility as Trustee under the Indenture and
certain related matters.
 
                                 UNDERWRITING

  The Company has been advised by the Underwriters that they propose initially
to offer the Debentures to the public at the public offering price set forth
on the cover page of this Prospectus, and to certain dealers at
 
                                      22

 
such price less a concession not in excess of .   % of the principal amount of
the Debentures. The Underwriters may allow, and such dealers may reallow, a
concession not in excess of .   % of the principal amount of the Debentures to
certain other dealers. After the initial public offering, the public offering
price and such concessions may be changed.
 
  In connection with this Offering, certain Underwriters and their affiliates
may engage in transactions that stabilize, maintain or otherwise affect the
market price of the Debentures. Such transactions may include stabilization
transactions effected in accordance with Rule 104 of Regulation M, pursuant to
which such persons may bid for or purchase Debentures for the purpose of
stabilizing their market price. The Underwriters also may create a short
position for the account of the Underwriters by selling more Debentures in
connection with the Offering than they are committed to purchase from the
Company, and in such case may purchase Debentures in the open market following
completion of the Offering to cover such short position. Any of the
transactions described in this paragraph may result in the maintenance of the
price of the Debentures at a level above that which might otherwise prevail in
the open market. None of the transactions described in this paragraph is
required, and, if they are undertaken, they may be discontinued at any time.
 
  The Company does not presently intend to list the Debentures on any
exchange. The Company has been advised by the Underwriters that they intend to
make a market in the Debentures but that they are not obligated to do so and
may discontinue market making at any time without notice. No assurance can be
given as to the liquidity of the trading market for the Debentures.
 
  The Underwriting Agreement provides that the Company will indemnify the
several Underwriters against certain liabilities, including liabilities under
the Securities Act of 1933, as amended, or contribute to payments the
Underwriters may be required to make in respect thereof.
 
                                LEGAL OPINIONS
 
  The validity of the Debentures will be passed upon for the Company by
Beckman, Weil, Shepardson and Faller, LLC, Cincinnati, Ohio, and for the
Underwriters by Mayer, Brown & Platt, Chicago, Illinois. The attorneys at
Beckman, Weil, Shepardson and Faller, LLC representing the Company in this
Offering beneficially own approximately 20,100 shares of the Company's common
stock.

ITEM 15. INDEMNIFICATION OF OFFICERS AND DIRECTORS.
 
  Section 1701.13(E) of the Ohio Revised Code provides that a corporation may
indemnify or agree to indemnify any person who was or is a party or is
threatened to be made a party to any threatened, pending, or completed action,
suit, or proceeding whether civil, criminal, administrative, or investigative,
other than an action by or in the right of the corporation, by reason of the
fact that the person is or was a director, officer, employee, or agent of the
corporation, or is or was serving at its request as a director, trustee,
officer, employee, or agent of another corporation, partnership, joint
venture, trust, or other enterprise, against expenses, including attorneys'
fees, judgments, fines and amounts paid in settlement actually and reasonably
incurred by the person in connection with such action, suit, or proceeding if
the person is determined under the procedure described in the Section to have
(a) acted in good faith and in a manner the person reasonably believed to be
in or not opposed to the best interests of the corporation, and (b) had no
reasonable cause to believe the conduct was unlawful in the case of any
criminal action or proceeding. However, with respect to expenses actually and
reasonably incurred in connection with the defense or settlement of any action
or suit by or in the right of the corporation to procure a judgment in its
favor, no indemnification is to be made (i) in respect of any claim, issue, or
matter as to which such person was adjudged liable for negligence or
misconduct in the performance of such person's duty to the corporation unless,
and only to the extent that, it is determined by the court upon application
that, despite the adjudication of liability, such person is fairly and
reasonably entitled to indemnity for such expenses as the court deems proper,
or (ii) in respect of any action or suit in which the only liability asserted
against a director is in connection with the alleged making of an unlawful
loan, dividend or distribution of corporate assets. The Section also provides
that such person shall be indemnified against expenses actually and reasonably
incurred by the person to the extent successful in defense of the actions
referred to above, or in defense of any claim, issue, or matter therein.
 
  The Company's Amended Articles of Incorporation provide for the
indemnification of officers and directors of the Company to the fullest extent
permitted by law. The above is a general summary of certain provisions of the
Ohio Revised Code and is subject in all cases to the specific provisions
thereof.
 
  The Company maintains an insurance policy covering its directors and
officers against certain civil liabilities, including liabilities under the
Securities Act of 1933.

ITEM 16. EXHIBITS AND FINANCIAL STATEMENT SCHEDULES.
 
  See Exhibit Index included herewith which is incorporated herein by
reference.
 
ITEM 17. UNDERTAKINGS.
 
  The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such
securities at that time shall be deemed to be the initial bona fide offering
thereof.
 
  Insofar as indemnification for liabilities arising under the Securities Act
or 1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the registrant of expenses
incurred or paid by a director, officer or controlling person of the
registrant in the successful defense of any action, suit or proceeding) is
asserted by such director, officer or controlling person in connection with
the securities being registered, the registrant will, unless in the opinion of
its counsel the matter has been settled by controlling precedent, submit to a
court of appropriate jurisdiction the question whether such indemnification by
it is against public policy and expressed in the Act and will be governed by
the final adjudication of such issue.
 
  The undersigned registrant hereby further undertakes that:
 
  For purposes of determining any liability under the Securities Act of 1933,
the information omitted from the form of prospectus filed as part of this
registration statement in reliance upon Rule 430A and contained in a form of
prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h)
under the Securities Act shall be deemed to be part of this registration
statement as of the time it was declared effective.
 
  For purposes of determining any liability under the Securities Act of 1933,
each post-effective amendment that contains a form of prospectus shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to
be the initial bona fide offering thereof.
