ITEM 1.   BUSINESS

(a)   GENERAL DEVELOPMENT OF BUSINESS

Ohio Casualty Corporation (the Corporation) was incorporated under the laws of
Ohio in August, 1969. The Corporation operates primarily as a holding company
and is principally engaged, through its direct and indirect subsidiaries, in the
business of property and casualty insurance and insurance premium finance.

The Corporation has two industry segments: property and casualty insurance and
insurance premium finance. The Corporation conducts its property and casualty
insurance business through The Ohio Casualty Insurance Company ("Ohio
Casualty"), an Ohio corporation organized in 1919, the Ohio Casualty's three
operating property and casualty insurance subsidiaries: West American Insurance
Company ("West American"), an Indiana corporation (originally incorporated under
the laws of the State of California) acquired in 1945; Ohio Security Insurance
Company ("Ohio Security"), an Ohio corporation acquired in 1962; and American
Fire and Casualty Company ("American Fire"), an Ohio corporation (originally
incorporated under the laws of the State of Florida) acquired in 1969. This
group of companies presently underwrites most forms of property and casualty
insurance. The Corporation conducts its premium finance business through Ocasco
Budget, Inc. ("Ocasco"), an Ohio corporation (originally incorporated under the
laws of the State of California) organized in 1960. Ocasco is a direct
subsidiary of Ohio Casualty. On May 31, 1995 the states of domicile of West
American and Ocasco changed to Indiana and Ohio, respectively, in connection
with the withdrawal from property and casualty insurance operations in
California as previously announced and as discussed elsewhere herein.

During 1995, the Corporation's third industry segment, life operations, was
discontinued. We found it increasingly difficult to achieve our targeted 16%
rate of return in this segment of our business. After extensive analysis, it was
determined that a 16% return could not be achieved without substantial capital
contributions and a dramatic overhaul of the life operations. Since this was a
small segment of our overall business, it was decided that this would not be a
prudent use of our capital. Therefore, on October 2, 1995, the Corporation
signed the final documents to reinsure the existing blocks of business and enter
a marketing agreement with Great Southern Life Insurance Company. The existing
blocks of business were reinsured through a 100% coinsurance arrangement with
Employer's Reassurance Corporation. As of December 31, 1996, $12.9 million of
the net ceding commission from the transaction remains unamortized. This will be
amortized into income over the remaining expected life of the underlying
reinsured policies, in this case, 14 years. It is anticipated that Great
Southern will replace Ohio Life as the primary carrier of these policies in the
second quarter of 1997 through an assumption. Upon assumption, the remaining
unamortized gain will be recognized. Net income from discontinued operations
amounted to $5.3 million or $.15 per share in 1996 compared with $4.4 million or
$.12 per share in 1995 and $5.9 million or $.16 per share in 1994.

(b)   FINANCIAL INFORMATION ABOUT INDUSTRY SEGMENTS

The revenues, operating profit and identifiable assets of each industry segment
for the three years ended December 31, 1996 are set forth in Note 11, Industry
Segment Information, in the Notes to the Consolidated Financial Statements on
page 33 of the Annual Report to Shareholders for the fiscal year ended December
31, 1996.

</TABLE>

Property and casualty net premiums written decreased 3.3% in 1996. New Jersey
net premiums written decreased 2.2%, however, private passenger automobile line
of business increased .4% due to continuing legislation requiring insurers to
accept all automobile risks meeting broad underwriting guidelines regardless of
risk concentration. Pennsylvania net premiums written decreased 9.5% principally
due to a 23% reduction in workers' compensation, as a result of management's
decision to limit writing due to poor underwriting experience.

      INVESTMENT OPERATIONS

Each of the companies in the Ohio Casualty Group must comply with the insurance
laws of its domiciliary state and of the other states in which it is licensed
for business. Among other things, these laws prescribe the kind, quality and
concentration of investments which may be made by insurance companies. In
general, these laws permit investments, within specified limits and subject to
certain qualifications, in federal, state and municipal obligations, corporate
bonds, preferred and common stocks, real estate mortgages and real estate.

The distribution of invested assets of the Ohio Casualty Group is determined by
a number of factors, including insurance law requirements, the Corporation's
liquidity needs, tax position, and general market conditions. In addition, our
business mix and liability payout patterns are considered. Adjustments are made
to the asset allocation from time to time. The Corporation has no real estate
investments. Assets relating to property and casualty operations are invested to
maximize after-tax returns with appropriate diversification of risk.

The following table sets forth the carrying values and other data of the
consolidated invested assets of the Ohio Casualty Group as of the end of the
years indicated:

</TABLE>


The consolidated fixed income portfolio (identified as "Total Bonds" in the
foregoing table) of the Ohio Casualty Group had a weighted average rating of
"A+" and an average stated maturity of twelve years as of December 31, 1996.

Investments in below investment grade securities (Standard and Poor's rating
below BBB-) had an aggregate carrying value of $184.6 million and an aggregate
amortized cost of $180.0 million at year-end 1996. Unrated securities had an
aggregate carrying value of $315.4 million and an aggregate amortized cost of
$308.3 million. At year-end 1995 and 1994, respectively, aggregate carrying
values for below investment grade securities were $203.9 million and $266.0
million and aggregate amortized costs were $203.7 million and $282.3 million. At
year-end 1995 and 1994, respectively, aggregate carrying values for unrated
securities were $286.3 million and $257.9 million and aggregate amortized costs
were $271.2 million and $262.8 million. Utilizing ratings provided by other
agencies such as the NAIC, categorizes $27.3 million of $315.4 million in
unrated securities as non-investment grade. This brings the aggregate market
value of non-investment grade securities to $211.9 million at December 31, 1996,
compared with $232.8 million and $302.2 million at year-end 1995 and 1994,
respectively.

ITEM 1.   CONTINUED

All of the Corporation's below investment grade investments (based on carrying
value) are performing in accordance with contractual terms and are making
principal and interest payments as required. The securities in the Corporation's
below investment grade portfolio have been issued by 78 corporate borrowers in
approximately 35 industries. At December 31, 1996, the Corporation's five
largest investments in securities totaled $54.8 million, and had an approximate
amortized cost of $51.6 million. None of these holdings individually exceeded
$21.6 million.

At December 31, 1996, the fixed income portfolio relating to property and
casualty operations totaled $2.2 billion which consisted of 90.6% investment
grade securities and 9.4% below investment grade and/or unrated securities. At
December 31, 1996, the fixed income portfolio relating to discontinued
operations totaled $41.0 million which consisted of 96.4% investment grade
securities and 3.6% high yield securities.

Investments in below investment grade securities have greater risks than
investments in investment grade securities. The risk of default by borrowers
which issue securities rated below investment grade is significantly greater
because these securities are generally unsecured and often subordinated to other
debt and these borrowers are often highly leveraged and are more sensitive to
adverse economic conditions such as a recession or a sharp increase in interest
rates. Investment grade securities are also subject to significant adverse risks
including the risks of re-leveraging and changes in control of the issuer. In
most instances, investors are unprotected with respect to such risks, the
effects of which can be substantial.

Yield (based on cost of investments) for the taxable fixed income portfolio was
8.4% and 8.7% at December 31, 1996 and 1995, respectively. Below investment
grade securities were yielding 9.5% and 10.1% at December 31, 1996 and 1995,
respectively, while investment grade securities were yielding 8.7% in 1996 and
7.5% in 1995. Yield for tax exempt securities was 6.4% at December 31, 1996 and
6.3% at December 31, 1995; however, this yield is not directly comparable to
taxable yield due to the complexity of federal taxation of insurance companies.

The Corporation remains committed to a diversified common stock portfolio. As of
December 31, 1996, the portfolio consisted of 65 separate issues, diversified
across 36 different industries; and the largest single position was 8.1% of the
portfolio. The portfolio strategy with respect to common stocks has been to
invest in companies whose stocks have below average valuations, yet above
average growth prospects.

Investment income is affected by the amount of new investable funds and
investable funds arising from maturities, prepayments, calls and exchanges as
well as the timing of receipt of such funds. In addition, other factors such as
interest rates at time of investment and the maturity, income tax status, credit
status and other risks associated with new investments are reflected in
investment income. Future changes in the distribution of investments and the
factors described above could affect overall investment income in the future;
however, the amount of any increase or decrease cannot be predicted. Further
details regarding investment distribution and investment income are described in
Note 2, Investments, in the Notes to Consolidated Financial Statements on pages
27 and 28 of the 1996 Annual Report to Shareholders.

Purchases of taxable fixed income securities in 1996 were as follows: $312.9
million of investment grade securities, $113.4 million of high yield securities
and $36.3 million of unrated securities. Purchases of tax-exempt and equity
securities in 1996 totaled $76.6 million and $74.4 million, respectively.

ITEM 1.   CONTINUED

Disposals (including maturities, calls, exchanges and scheduled prepayments) of
taxable fixed income securities in 1996 were as follows: $266.1 million of
investment grade securities, $160.3 million of high yield securities and $13.4
million of unrated securities. Dispositions of tax-exempt and equity securities
in 1996 totaled $163.8 million and $129.7 million, respectively. During 1993,
the Financial Accounting Standards Board issued Statement of Financial
Accounting Standards 115, "Accounting for Certain Investments in Debt and Equity
Securities". This statement was adopted on January 1, 1994, and required the
Corporation to classify equity securities and debt securities into the following
categories: 1) held to maturity; 2) trading; 3) available for sale.

The Corporation continues to have no exposure to futures, forwards, caps,
floors, or similar derivative instruments as defined by Statement of Financial
Accounting Standards No. 119. However, as noted in footnote number 13 on page 34
of the Annual Report to Shareholders, we have an interest rate swap with Chase
Manhattan Bank covering our term loan. This swap is not classified as an
investment but rather as a hedge against a portion of the variable rate loan.

All holdings were placed in the "available for sale" category. This accounting
change increased shareholders' equity by $116.1 million in 1994. Consolidated
net realized investment gains (before taxes) in 1996 totaled $49.7 million,
$1.41 per share. Included in this amount are approximately $6.5 million in
writedowns of the carrying values of certain securities the Corporation
determined had an other than temporary decline in value.

      SHARE REPURCHASES

During 1990 the Board of Directors of Ohio Casualty Corporation authorized the
additional purchase of as many as 3,000,000 (as adjusted for 1994 stock split)
shares of its common stock through open market or privately negotiated
transactions. 264,600 shares were repurchased during 1996 for $9.2 million.
613,900 shares were repurchased during 1995 for $20.9 million and 50,000 shares
were repurchased during 1994 for $1.4 million. The remaining repurchase
authorization is 2,071,500 shares as of December 31, 1996.

      LIABILITIES FOR UNPAID LOSS AND LOSS ADJUSTMENT EXPENSES

Liabilities for loss and loss adjustment expenses are established for the
estimated ultimate costs of settling claims for insured events, both reported
claims and incurred but not reported claims, based on information known as of
the evaluation date. As more information becomes available and claims are
settled, the estimated liabilities are adjusted upward or downward with the
effect of increasing or decreasing net income at the time of adjustments. Such
estimated liabilities include direct costs of the loss under terms of insurance
policies as well as legal fees and general expenses of administering the claims
adjustment process. The liabilities for claims incurred in accident years 1995,
1994 and 1993 were reduced in the subsequent year as shown below:

ITEM 1.   CONTINUED


In the normal course of business, the Ohio Casualty Group is involved in
disputes and litigation regarding terms of insurance contracts and the amount of
liability under such contracts arising from insured events. The liabilities for
loss and loss adjustment expenses include estimates of the amounts for which the
Ohio Casualty Group may be liable upon settlement or other conclusion of such
litigation.

Because of the inherent future uncertainties in estimating ultimate costs of
settling claims, actual loss and loss adjustment expenses may deviate
substantially from the amounts recorded in the Corporation's consolidated
financial statements. Furthermore, the timing, frequency and extent of
adjustments to the estimated liabilities cannot be accurately predicted since
conditions and events which established historical loss and loss adjustment
expense development and which serve as the basis for estimating ultimate claims
cost may not occur in the future in exactly the same manner, if at all.

The anticipated effect of inflation is implicitly considered when estimating the
liability for losses and loss adjustment expenses based on historical loss
development trends adjusted for anticipated changes in underwriting standards,
policy provisions and general economic trends.

The following table presents an analysis of losses and loss adjustment expenses
and related liabilities for the periods indicated. The accounting policies used
to estimate liabilities for losses and loss adjustment expenses are described in
Note 9, Losses and Loss Reserves, in the Notes to Consolidated Financial
Statements on page 32 of the 1996 Annual Report to Shareholders.

ITEM 1.   CONTINUED


      COMPETITION

More than 3,200 property and casualty insurance companies compete in the United
States and no one company or company group has a market share greater than
approximately 12%. The Ohio Casualty Group ranked as the forty-second largest
property and casualty insurance groups in the United States based on net
insurance premiums written in 1995, the latest year for which statistics are
available. The Ohio Casualty Group competes with other companies on the basis of
service, price and coverage.

      STATE INSURANCE REGULATION

General. The Corporation and the Ohio Casualty Group are subject to regulation
under the insurance statutes, including the holding company statutes, of various
states. Ohio Casualty, American Fire and Ohio Security are all domiciled in
Ohio. West American is domiciled in Indiana. Collectively, the Ohio Casualty
Group is authorized to transact the business of insurance in the District of
Columbia and all states except Maine. The Ohio Casualty Group is subject to
examination of their affairs by the insurance departments of the jurisdictions
in which they are licensed.

State laws also require prior notice or regulatory agency approval of changes in
control of an insurer or its holding company and of certain material
intercorporate transfers of assets within the holding company structure. Under
applicable provisions of the Indiana insurance statutes ("Indiana Insurance
Law") and the Ohio insurance statutes (the "Ohio Insurance Law"), a person would
not be permitted to acquire direct or indirect control of the Corporation or any
of the Ohio Casualty Group companies domiciled in such state, unless such person
had obtained prior approval of the Indiana Insurance Commissioner and the Ohio
Superintendent of Insurance, respectively, for such acquisition. For the
purposes of the Indiana Insurance Law and the Ohio Insurance Law, any person
acquiring more than 10% of the voting securities of a company is presumed to
have acquired "control" of such company.

Proposition 103 was passed in the State of California in 1988 in an attempt to
legislate premium rates for that state. Even after considering investment
income, total returns in California have been less than what would be considered
"fair" by any reasonable standard. During the fourth quarter of 1994, the State
of California billed the Corporation $59.9 million for Proposition 103
assessment. In February 1995, California revised this billing to $47.3 million
due to California Senate Bill 905 which permits reduction of the rollback due to
commissions and premium taxes paid. The billing was revised again in August of
1995 and at present the State has indicated the Corporation should not be
required to pay in excess of $42.1 million plus interest as a Proposition 103
assessment. As a result, the Corporation's reserve for this alleged liability is
$74.4 million at December 31, 1996.

The Corporation is currently involved in hearings with the State of California.
The final arguments are expected to conclude in the first quarter of 1997. A
ruling from the Administrative Law Judge is expected in the second quarter of
1997. At that time, the Insurance Commissioner will have 60 days to take the
ruling under advisement and return with a final ruling.

The Corporation will continue to challenge the validity of any rollback and
plans to continue negotiations with Department officials. It is uncertain when
this will be resolved. To date, the Corporation has paid $2.9 million in legal
costs related to the withdrawal, Proposition 103 and Fair Plan assessments.

ITEM 1.   CONTINUED


The State of New Jersey has historically been a profitable state for the
Corporation. In recent years, however, the legislative environment in that state
has deteriorated. Due to legislative rules and regulations designed to make
insurance less expensive and more easily obtainable for New Jersey residents,
our results have been adversely impacted. In order to meet our state imposed
assessment obligations under the Fair Automobile Insurance Reform Act, the
Unsatisfied Claim and Judgment fund and the Market Transition Facility, the
Corporation has incurred expenses of $3.6 million in 1996, $3.7 million in 1995
and $6.4 million in 1994. These assessments have negatively affected our
combined ratios by .3, .3 and .5 points in the three years, respectively.

NATIONAL ASSOCIATION OF INSURANCE COMMISSIONERS. The National Association of
Insurance Commissioners (the "NAIC") annually calculates a number of financial
ratios to assist state insurance regulators in monitoring the financial
condition of insurance companies. A "usual range" of results for each ratio is
used as a benchmark. Departure from the usual range on four or more of the
ratios could lead to inquiries from individual state insurance commissioners as
to certain aspects of a company's business. None of the property and casualty
companies of the Ohio Casualty Group had more than two NAIC financial ratios
that were outside the usual range in the last five calendar years.

Beginning in 1994, the NAIC requires inclusion of a risk-based capital
calculation in the Annual Statements. The risk-based capital model is used to
establish standards which relate insurance company statutory surplus to risks of
operations and assist regulators in determining solvency requirements. The model
is based on four risk factors in two categories: asset risk, consisting of
investment risk and credit risk; and underwriting risk, composed of loss
reserves and premiums written risks. Based on current calculations, all of the
Ohio Casualty Group companies have at least four times the necessary capital to
conform with the risk-based capital model.

The States of Ohio and Indiana have adopted the NAIC model law limiting dividend
payments by insurance companies. This law allows dividends to equal the greater
of 10% of policyholders surplus or net income determined as of the preceding
year end without prior approval of the Insurance Department. For 1996, $123.4
million of policyholder surplus are not subject to restrictions or prior
dividend approval.

      EMPLOYEES

At December 31, 1996, the Ohio Casualty Group had approximately 3,390 employees
of which approximately 1,288 were located in Hamilton, Ohio.

      IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS

Recently the FASB issued Statement of Financial Accounting Standards No. 128,
Earnings Per Share, which supersedes APB Opinion No. 15, Earnings Per Share.
This standard replaces the primary EPS requirements with a basic EPS computation
and requires a dual presentation of basic and diluted EPS for those companies
with complex capital structures. The Corporation intends to adopt the standards
of Statement No. 128 for financial statements issued after December 15, 1997.
The impact of this statement is expected to be immaterial on the Corporation's
EPS calculation.

standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the consolidated financial position of Ohio Casualty
Corporation and subsidiaries as of December 31, 1996, 1995 and 1994, and the
consolidated results of their operations and their cash flows for the years then
ended in conformity with generally accepted accounting principles. In addition,
in our opinion, the financial statement schedules referred to above, when
considered in relation to the basic financial statements taken as a whole,
present fairly, in all material respects, the information required to be
included therein.

As discussed in Notes 1 and 6 to the consolidated financial statements, the
Corporation changed its method of accounting for debt and equity securities and
post-employment benefits in 1994.

                       MANAGEMENT'S DISCUSSION & ANALYSIS



RESULTS OF OPERATIONS

       Net income increased 2.8% for 1996 to $102.5 million or $2.91 per share
while the combined ratio increased by 5.5 points to 109.5%. Losses were
negatively impacted by catastrophes with $62.2 million of catastrophe losses in
1996 versus only $27.3 million in 1995. The underwriting expense ratio was up
slightly due to a decline in premiums written; however, underwriting expenses
actually declined over $3.8 million versus 1995. Net premiums written declined
for the fourth straight year to $1.2 billion. The premium decline is
attributable to the Corporation's continued repositioning strategy where coastal
exposures are reduced, agents with insufficient premium volume are canceled, and
states with poor regulatory or legal environments are avoided. During 1996, 254
agents were canceled accounting for more than $27.1 million in written premium.
The largest decline in premium occurred in the workers' comp line of business
with a 17.9% decline. The largest premium decline in individual states came in
Pennsylvania with a $11.9 million decline. With our repositioning completed, it
is believed that our efforts will be rewarded with overall premium growth in
1997. As a leading indicator, our key agents showed positive growth for 1996.

       Net cash used by operations was $20.3 million compared with cash used of
$74.7 million in 1995 and cash generated of $45.7 million in 1994. Investing
activities produced net cash of $119.1 million in 1996, compared with $169.2
million in 1995 and $39.3 million in 1994. Dividend payments were $56.4 million
in 1996 compared with $54.3 million in 1995 and $52.6 million in 1994. Total
cash used for financing activities was $75.4 million in 1996 compared with $85.0
million in 1995 and $86.8 million in 1994. Overall, total cash generated in 1996
was $23.3 million, compared with $9.6 million in 1995 versus net cash used of
$1.8 million in 1994.

       The fourth quarter of 1996 yielded a combined ratio of 98.6%, the same
result as the fourth quarter of 1995. The fourth quarter results were especially
encouraging after the heavy catastrophe losses suffered in the first three
quarters of the year.

       Branch consolidation continued in 1996 with the number of branches
decreasing from 36 in 1995 to 29 in 1996. The efficiencies that are produced
through these consolidations can be seen in our declining underwriting expenses.
The Corporation expects to close an additional 15 branches in 1997.

       In order to evaluate corporate performance relative to shareholders'
expectations, the Corporation calculates a five-year average return on equity.
Net income and unrealized gains and losses on investments are included in the
calculation to derive a total return. A five-year average is used to correspond
to our planning horizon and emphasize consistent long term returns, not
intermediate fluctuations. At December 31, 1996, our five-year average return on
equity was 13.9% down from the 16% calculated at December 31, 1995.

PROPERTY AND CASUALTY

       In a continuing effort to maximize the use of technology in our industry,
we expanded our internet applications in 1996. We now quote auto insurance
through the internet in 27 states and have begun to log sales from this
endeavor. In addition to the direct benefits of our internet presence, we
receive collateral sales through increased name recognition. This is just
another part of our continuing efforts at becoming more customer focused. A
significant part of this focus is maximizing the ease and convenience of buying
our product.

       In addition to identifying new marketing opportunities, we continue
working to improve customer retention through improved service and better
products thus leading to increased premium income and profitability. This focus
on our policyholders has yielded a policyholder retention of 84.1% in 1996 and
83.1% in 1995. Our goal is to achieve a minimum 85% retention ratio. By
retaining valued customers, the Corporation is able to improve premium volume
while limiting the higher expense associated with new business underwriting.

       Property and casualty operating income was $66.1 million, $1.88 per
share, in 1996 compared with $92.5 million, $2.59 per share, in 1995 and $79.3
million, $2.20 per share in 1994. Catastrophe losses in 1996 totaled $62.2
million compared with $27.3 million in 1995 and $36.6 million in 1994. The
losses in 1996 came from 39 separate catastrophes, primarily winter and spring
storms in the Midwest. Catastrophe losses added 5.1 points to the combined ratio
in 1996 compared with 2.2 points in 1995 and 2.8 points in 1994.

       Statutory surplus, a traditional insurance industry measure of strength
and underwriting capacity, was $984.9 million at December 31, 1996 compared with
$876.9 million at December 31, 1995 and $660.0 million at December 31, 1994. The
increases in 1996 and 1995 were due primarily to the unrealized gains in our
investment portfolio.

       The ratio of premiums written to statutory surplus has not exceeded 1.7
to 1 for any property and casualty company in The Ohio Casualty Group in any of
the last three years. This ratio is one of the measures used by insurance
regulators to gauge the financial strength of an insurance company and indicates
the ability of the Corporation to grow by writing additional business.
Currently, the Corporation's ratio is 1.2 to 1. Ratios below 3 to 1 generally
indicate additional capacity and financial strength.

       The National Association of Insurance Commissioners has developed a "Risk
Based Capital" formula for property and casualty insurers and life insurers. The
formulas are intended to measure the adequacy of an insurer's capital given the
asset structure and product mix of the company. Under the current formulas, all
insurance companies in The Ohio Casualty Group have at least twice the necessary
capital.

</TABLE>

       The premium growth in New Jersey is being driven primarily by the private
passenger auto line of business which grew 11.1% in 1995 and an additional .4%
in 1996. New Jersey requires insurers to write all auto business that meets
underwriting guidelines regardless of risk concentration. Net written premiums
for this state were $221.2 million for 1996.

PREMIUM FINANCE

       Premium finance operating income decreased to $.3 million in 1996
compared with $.7 million in 1995 and 1994. Revenues were again down due to
repositioning and the movement away from premium financing to our commercial
lines direct billing system.

DISCONTINUED OPERATIONS

       During 1995, the Corporation's life operations were discontinued. We
found it increasingly difficult to achieve our targeted 16% rate of return in
this segment of our business. After extensive analysis, it was determined that a
16% return could not be achieved without substantial capital contributions and a
dramatic overhaul of the life operations. Since this was a small segment of our
overall business, it was decided that this would not be a prudent use of our
capital. Therefore, on October 2, 1995, the Corporation signed the final
documents to reinsure the existing blocks of business and enter a marketing
agreement with Great Southern Life Insurance Company. This will provide our
agents and policyholders access to quality life insurance products to meet their
financial needs. The existing blocks of business were reinsured through a 100%
coinsurance arrangement. As of December 31, 1996, $12.9 million of the net
ceding commission from the transaction remains unamortized, compared with $16.7
million unamortized at December 31, 1995. This will be amortized into income
over the expected remaining life of the underlying reinsured policies, in this
case, 14 years. An assumption is scheduled for the second quarter of 1997
whereby Great Southern will legally replace Ohio Life as the primary carrier on
these policies at which time the remaining unamortized gain will be recognized.
Until the assumption takes place, investments are retained in the Ohio Life
Insurance Company to support its primary liability on the reinsured business.
These investments generate ongoing investment income. Once the assumption
occurs, these investments will be freed to support continuing operations. Net
income from discontinued operations amounted to $5.2 million or $.15 per share
in 1996 compared with $4.4 million or $.12 per share in 1995 and $5.9 million or
$.16 per share in 1994.

REINSURANCE

       In order to preserve capital and shareholder value, Ohio Casualty
Corporation purchases reinsurance to protect the Corporation against large or
catastrophic losses. Three separate reinsurance programs have been established
to protect the Corporation. The Property Per Risk contract covers Ohio Casualty
in the event that an insured sustains a property loss in excess of $1.0 million
in a single insured event. The Casualty Per Occurrence contract covers the
Corporation in the event that an insured sustains a liability loss in excess of
$1.0 million in a single insured event. On both of these contracts, Ohio
Casualty pays the first $1.0 million in losses. Property reinsurance covers
$15.0 million in excess of the retention. Casualty reinsurance covers $11.0
million in excess of the retention; and workers' compensation reinsurance covers
$74.0 million in excess of the retention. In 1997, the Corporation added two
layers of Workers' Compensation Catastrophe Excess of Loss protection. These
layers provide $51.0 million in additional coverage over the 1996 program.

       The Catastrophe Reinsurance contract protects the Corporation against an
accumulation of losses arising from one defined catastrophic occurrence or
series of events. The 1996 program provided $125.0 million coverage in excess of
the Corporation's $25.0 million retention. An additional layer provided $50.0
million in excess of $150.0 million coverage for New Jersey only. The 1997
Catastrophe Program provides $150.0 million coverage in excess of the
Corporation's $25.0 million retention. Total reinsurance protection increased
20% in 1997 due to a larger participation by reinsurers. The New Jersey-only
layer was non-renewed for the 1997 program. Over the last twenty years, there
were two events that triggered coverage under our catastrophe contract. Losses
and loss adjustment expenses from the Oakland Fires in 1991 and Hurricane Andrew
in 1992 totaled $31.4 million and $28.9 million, respectively. Both of these
losses exceeded our prior retention amount of $13.0 million. The Corporation
recovered $29.5 million from reinsurers as a result of these events. Our
reinsurance limits are designed to cover our exposure to an event expected to
occur once every 300 years.

       Since the Corporation's reinsurance protection is an important component
in our financial plan, we closely monitor the financial health of each of our
reinsurers. Annually, financial statements are reviewed and various ratios
calculated to identify reinsurers who have ceased to meet our





<PAGE>   7

high standards of financial strength. If any reinsurers fail these tests, they
are removed from the program at renewal.

LOSS AND LOSS ADJUSTMENT EXPENSES

       The Corporation's largest liabilities are the reserves for losses and
loss adjustment expenses. Loss and loss adjustment expense reserves are
established for all incurred claims and are carried on an undiscounted basis
before any credits for reinsurance recoverable. These reserves amounted to $1.6
billion at December 31, 1996 and 1995 compared with $1.7 billion at December 31,
1994. As claims are paid, the related reserves are closed and any under- or
over-estimation of the claim reserve is closed to net income at that time.

       In 1996, the Corporation continued the use of an 800 number for direct
reporting of claims. The percentage of all claims handled by direct reporting
was approximately 50% in 1996. This was almost two-thirds more than was handled
by direct reporting in 1995. The Corporation routinely receives positive
feedback on this option from our policyholders.

       In recent years, environmental liability claims have expanded greatly in
the insurance industry. Fortunately, Ohio Casualty has a substantially different
mix of business than the industry. We have historically written small commercial
accounts, and have not attracted significant manufacturing liability coverage.
As a result, our environmental liability claims are substantially below the
industry average. Our liability business reflected our current mix of
approximately 67% contractors, 14% building/premises, 14% mercantile and only 5%
manufacturers. Within the manufacturing category, we have concentrated on the
light manufacturers which further limits our exposure to environmental claims.
In 1996 the Corporation analyzed incurred but not reported reserves for general
liability and commercial multiple peril to segregate between asbestos and
environmental losses and all other losses. As a result of this analysis, an
additional $27.4 million in reserves was identified as asbestos and
environmental related. Based on this examination, an estimated liability of
$41.0 million was carried at year end 1996. Of this, reserves on known claims
totaled $13.6 million at year end 1996 compared with $14.4 million and $10.4
million at year end 1995 and 1994, respectively. Approximately $5.2 million in
reserves are for asbestos claims. The remainder are primarily for pre-1985
pollution claims. These loss estimates are based on the currently available
information. However, given the expansion of coverage and liability by the
courts and legislatures, there is some uncertainty as to the ultimate liability.
The Corporation's insurance subsidiaries changed their pollution exclusion
policy language between 1985 and 1987 to effectively eliminate these coverages.

CALIFORNIA WITHDRAWAL

       On June 15, 1992, the Corporation announced its intention to withdraw its
business operations from California due to the lack of profitability and the
difficult regulatory environment. In December 1992, the Corporation stopped
writing business in California and filed a withdrawal plan with the California
Department of Insurance.

       Under the terms of the plan, The Ohio Casualty Insurance Company, Ohio
Security Insurance Company, and West American Insurance Company would withdraw
from California, leaving American Fire and Casualty Company licensed to wind
down the affairs of the Group. Also, the plan required the withdrawing companies
to transfer their California liabilities to American Fire and Casualty Company
along with assets to secure those liabilities. In April 1995, the California
Department of Insurance gave final approval for withdrawal and the Corporation
implemented the withdrawal plan.

       Proposition 103 was passed in the State of California in 1988 in an
attempt to legislate premium rates for that state. Based on previous statements
by the California Department of Insurance and the Corporation's lack of
profitability in the state, it was concluded that no significant liability for
premium rollbacks existed. However, at the end of 1994, and again in 1995, the
State of California billed the Corporation for varying amounts. To date, the
Corporation has received three billings and one set of written testimony from
the State, each asserting a different liability. 





<PAGE>   8

The most current indication of the State's position is the filed written
testimony of the State's expert witness indicating the Corporation should not be
required to pay in excess of $42.1 million plus interest as a Proposition 103
assessment. Our current reserve of $74.4 million is based on this testimony. We
made no additions to reserves for principal amounts in 1996; however, we
continue to accrue interest on the assessed liability. Reserving for this
alleged liability negatively impacted net income by $2.7 million or $.08 per
share in 1996, $14.9 million or $.42 per share in 1995 and $30.7 million or $.85
per share in 1994.

       The Corporation is currently involved in Proposition 103 hearings with
the State of California. The final arguments are expected to conclude in the
first quarter of 1997. A ruling from the Administrative Law Judge is expected in
the second quarter of 1997. At that time the Insurance Commissioner will have 60
days to take the ruling under advisement and return with his ruling. The
Corporation will continue to challenge the validity of any rollback and plans to
continue negotiations with Department officials. It is uncertain when this will
ultimately be resolved.

INVESTMENTS

       Consolidated pre-tax investment income from continuing operations
decreased 2.5% to $183.3 million in 1996 compared with $188.1 million in 1995
and $185.7 million in 1994. Of greater importance, after-tax investment income
totaled $138.6 million in 1996 compared with $138.4 million in 1995 and $142.5
million in 1994. Pre-tax and after-tax investment income comparisons versus 1995
are impacted by an increased exposure to municipal bonds in 1996. Investment
income growth over the past few years has been impacted by negative cash flow
from underwriting activities, a decline in average portfolio yields and the sale
of our life insurance subsidiary. The negative cash flow from underwriting
activities has been precipitated by our strategic repositioning. Cash flow also
continues to be impacted by our share repurchase program.

       At year end 1996, consolidated investments had a carrying value of $3.1
billion. The excess of market value over cost was $499.7 million, compared with
a $465.9 million excess at year end 1995 and $105.4 million at year end 1994.
The increase in the excess of market value over cost in 1996 was attributable to
the strong performance of our equity portfolio, offset somewhat by a decline in
the value of our fixed income portfolios. After-tax realized investment gains
from continuing operations amounted to $32.3 million in 1996 compared with $4.0
million in 1995 and $14.2 million in 1994.

       We continue to have no exposure to futures, forwards, caps, floors, or
similar derivative instruments as defined by Statement of Financial Accounting
Standards No. 119. However, as noted in footnote number 13, we have an interest
rate swap with Chase Manhattan Bank covering our term loan. This swap is not
classified as an investment but rather as a hedge against a portion of the
variable rate loan. As of December 31, 1996, Ohio Casualty maintained a $446.9
million mortgage-backed securities portfolio compared with $403.1 million at
December 31, 1995. The majority of our mortgage-backed securities holdings are
less volatile planned amortization class, sequential structures and agency
pass-through securities. $27.0 million of this portfolio is invested in more
volatile bond classes (e.g. interest-only, super-floaters, inverses).

       Ohio Casualty's fixed income strategy has been to maintain a portfolio
with a laddered maturity structure and an intermediate duration. We believe that
our portfolio composition and duration continue to be appropriate for our
insurance business. Further, we do not try to time the financial markets.
Instead, we believe it prudent to remain fully invested at all times, subject
only to our liquidity needs.

       Tax exempt bonds were 34.4% of the fixed income portfolio at year end
1996 versus 37.3% at December 31, 1995. Although the year over year comparison
reflects a decreased exposure to municipals, our average exposure throughout the
year was substantially higher than it was in 1995. This higher average exposure
reflects our internal tax planning strategy as well as our belief that, coming
into 1996, municipals were attractive relative to taxable bond alternatives. As




<PAGE>   9

1996 unfolded and underwriting results were factored into our tax planning
strategy, the municipal portfolio was reduced accordingly.

       Our commitment to a diversified, growth-oriented equity portfolio remains
unchanged. Equity investments have increased as a percentage of our consolidated
portfolio from 21.4% in 1995 to 23.5% at year end 1996. This increase is
entirely attributable to market appreciation of existing investments as opposed
to commitment of new funds. In fact, no new funds have been allocated to
equities in the last two years.

       In 1994, the Corporation implemented SFAS 115, "Accounting for Certain
Investments in Debt and Equity Securities." This statement requires the
classification of security investments into three categories: held to maturity,
trading and available for sale. In order to maintain the ability to actively
manage our fixed income portfolios, the Corporation has elected to place all of
our fixed income holdings in the available-for-sale category. Therefore, all of
our bond investments are now valued at market for balance sheet purposes.

       During 1996, Ohio Casualty Corporation purchased 264,600 shares of its
common stock at a cost of $9.2 million compared with 613,900 shares for $20.9
million in 1995. The Corporation is currently authorized to repurchase 2.1
million additional shares of its common stock to be held as treasury shares for
stock options or other general corporate purposes. Since the beginning of 1987,
we have repurchased 10.7 million shares at an average cost of $22 per share. We
believe that when the market value of our stock fails to reflect the prospects
of our operations, repurchasing shares is a prudent use of our capital. In the
future, we intend to continue repurchasing shares when doing so makes economic
sense for the Corporation and its shareholders.

YEAR 2000

       Recently, the "Year 2000 Problem" has received extensive press in the
insurance industry. Apparently, many of our competitors are making large
expenditures in order to convert their computer systems to recognize the year
2000. Most computer systems were originally written with two digit date fields.
Therefore, the computer believes that the difference between `99 and `00 is a
negative 99 years instead of one year. Since the late 1980's, Ohio Casualty has
been converting our computer systems to be year 2000 compliant as we modified
and adjusted the programs for other purposes. As such, the Corporation has not
had to make such a dedicated and expensive effort to fix the problem. Currently,
over 60% of our systems are already compliant, with the remainder expected over
the next two years. To date, we have spent approximately $.3 million and expect
to spend an additional $.2 million to complete our efforts.

                              NOTES TO CONSOLIDATED
                              FINANCIAL STATEMENTS



NOTE  1  --  ACCOUNTING POLICIES

A. The consolidated financial statements have been prepared on the basis of
generally accepted accounting principles and include the accounts of Ohio
Casualty Corporation and its subsidiaries. All significant inter-company
transactions have been eliminated. All dollar amounts except share and per 
share data are in thousands of dollars.

B. Effective January 1, 1994, the Corporation adopted Statement of Financial
Accounting Standards 115, "Accounting for Certain Investments in Debt and Equity
Securities". Under the provisions of SFAS No. 115 investment securities should
be classified upon acquisition into one of the following categories:

       (1)  held to maturity securities
       (2)  trading securities
       (3)  available for sale securities

     Available for sale securities are those securities that would be available
to be sold in the future in response to liquidity needs, changes in market
interest rates, and asset-liability management strategies, among others.
Available for sale securities are reported at fair value, with unrealized gains
and losses excluded from earnings and reported as a separate component of
shareholders' equity, net of deferred tax. Equity securities are carried at
quoted market values and include non-redeemable preferred stocks and common
stocks. Fair values of fixed maturities and equity securities are determined on
the basis of dealer or market quotations or comparable securities on which
quotations are available.

     Prior to adoption of SFAS No. 115, securities purchased, where the
Corporation had both the intent and ability to hold to maturity, were recorded
at cost adjusted for accumulated amortization of premium and accretion of
discount. Securities purchased for trading purposes are immaterial and are not
presented separately in the Income Statement and the Balance Sheet.

     As of January 1, 1994, the majority of fixed maturity investments,
including bonds, notes and redeemable preferred stock, were reclassified as
"available for sale". This necessitated them being marked to market. This
accounting change resulted in an increase to shareholders' equity of $116,100
net of tax as of January 1, 1994 and had an immaterial effect on net income.

     Short-term investments include commercial paper and notes with original
maturities of 90 days or less and are stated at cost or amortized cost which
approximates market. Short-term investments are deemed to be cash equivalents.

     Realized gains or losses on disposition of investments are determined on
the basis of specific cost of investments.

C. Property and casualty insurance premiums are earned principally on a monthly
pro rata basis over the term of the policy; the premiums applicable to the
unexpired terms of the policies are included in unearned premium reserve.

D. Acquisition costs incurred at policy issuance net of applicable ceding
commissions are deferred and amortized over the term of the policy for property
and casualty insurance, over the estimated life in proportion to future profits
of universal life type contracts and over the estimated premium paying period
for other life insurance contracts. Deferred policy acquisition costs are
reviewed to determine that they do not exceed recoverable amounts, including
anticipated investment income.

E. Liabilities for future policy benefits are computed based on contract terms
and issue date using interest rates ranging from 4% to 8 3/4%, select and
ultimate mortality experience and industry withdrawal experience. Interest rates
on $230,843 of such liabilities in 1996, $293,732 in 1995 and $287,190 in 1994
are periodically adjusted based on market conditions. Fair value is determined
by discounting cash flows at current market interest rates.

F. Deferred income taxes result from temporary differences between financial and
taxable income.

G. Property and equipment are carried at cost less accumulated depreciation.
Depreciation is computed principally on the straight-line method over the
estimated lives of the assets.

H. The Corporation's primary products consist of insurance for: personal auto,
commercial property, homeowners, workers' compensation and other miscellaneous
lines. Ohio Casualty operates through the independent agency system in 38
states. Of net premiums written, approximately 18.3% was generated in the State
of New Jersey, 10.2% in Ohio and 9.4% in Pennsylvania. The insurance industry is
subject to heavy regulation that differs by state. A dramatic change in
regulation in a given state may have a material adverse impact on the
Corporation.

I. Net income per share of common stock is based on the weighted average number
of shares outstanding during the period. Dilution arising from stock options is
insignificant.

J. The Corporation is dependent on dividend payments from its insurance
subsidiaries in order to meet operating expenses and to pay dividends. Insurance
regulatory authorities impose various restrictions and prior approval
requirements on the payment of dividends by insurance companies and holding
companies. At December 31, 1996, approximately $123,360 of retained earnings are
not subject to restriction or prior dividend approval requirements.

K. The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of financial statements, and the
reported amounts of revenues and expenses during the reporting period. Actual
results could differ from those estimates.

     Certain securities were determined to have other than temporary declines in
book value and were written down through realized investment losses. Total
write-downs were $19,456, $26,290 and $19,030 as of 1996, 1995 and 1994,
respectively, representing a reduction in value of $7,055, $9,696 and $6,910 on
fixed maturities and $12,401, $16,595 and $12,120 on equity securities.

     Proceeds from maturities and sales of investments in debt securities during
1996, 1995 and 1994 were $603,364, $1,062,462 and $865,218, respectively. Gross
gains of $14,257, $20,834 and $21,694 and gross losses of $10,388, $24,500 and
$13,276 were realized on those maturities and sales in 1996, 1995 and 1994,
respectively.

     Covered call options are written on stocks and bonds in the investment
portfolio. As a writer of options, a premium is received at the outset with the
risk of losing the appreciation if the price of the underlying financial
instrument rises above the option strike price. There were no options on stock
outstanding at December 31, 1996 or 1994. The outstanding stock options for 1995
were $1,125. There were no options on bonds outstanding at December 31, 1996,
1995 or 1994.

     Market values of securities can fluctuate greatly in the near term based on
such factors as: interest rates, unemployment rates, inflation, monetary policy
and general economic conditions.

     Tax years 1990 through 1992 are being examined by The Internal Revenue
Service. Management believes there will not be a significant impact on the
financial position or results of operations of the Corporation as a result of
this audit.

     The components of the net deferred tax asset (liability) were as follows:

     Taxes paid amounted to $16,336 in 1996, $37,346 in 1995 and $17,886 in
1994. Although realization of deferred assets is not assured, estimates indicate
that current levels of taxable income will comfortably support the realization
of the net deferred tax asset in future years. As such, no valuation allowance
has been recorded. The amount of the deferred tax asset considered realizable,
however, could be reduced in the near term if estimates of future taxable income
are reduced.

NOTE 6  -- EMPLOYEE BENEFITS

</TABLE>

     The  postretirement  plan  measurement  date is October 1 for 1996 and 1995
and December 31 for 1994. The measurement date was changed in 1995 to allow for
more timely actuarial calculations.

     Increasing the assumed health care cost trend by 1 percentage point in each
year would increase the accumulated postretirement benefit obligation as of
December 31, 1996 by approximately $9,491 and increase the postretirement
benefit cost for 1996 by $1,685.

     In 1994 the Corporation's health care plan was changed from an indemnity
plan to a predominately managed care plan. Retired employees continue to be
eligible to participate in the health care and life insurance plans. Benefit
costs are accrued based on actuarial projections of future payments. There are
currently 3,156 active employees and 1,335 retired employees covered by these
plans.

     Employees may contribute a percentage of their compensation to a savings
plan. A portion of employee contributions is matched by the Corporation and
invested in Corporation stock purchased on the open market by trustees of the
plan.

     In the first quarter of 1994, the Corporation adopted the provisions of
SFAS 112, "Employers Accounting for Post-Employment Benefits". The effect of
this accounting change in 1994 was a $644 after-tax reduction in net income.

NOTE 7  -  STOCK OPTIONS

The Corporation is authorized under provisions of the 1993 Stock Incentive
Programs to grant options to purchase 1,293,500 shares of the Corporation's
common stock to key executive employees and directors at a price not less than
the fair market value of the shares on dates the options are granted. The
options granted may be either "Incentive Stock Options" or "Nonqualified Stock
Options" as defined by the Internal Revenue Code; the difference in the option
plans affects treatment of the options for income tax purposes by the individual
employee and the Corporation. The options are non-transferable and exercisable
at any time after the vesting requirements are met. Option expiration dates are
five and ten years from the grant date. Options vest at 100% six months from the
grant date or at 33% per year for three consecutive years from the date of the
grant. At December 31, 1996, 1,115,500 remaining options may be granted.

     In addition, the 1993 Stock Incentive Program provides for the grant of
Stock Appreciation Rights in tandem with the stock options. Stock Appreciation
Rights provide the recipient with the right to receive payment in cash or stock
equal to appreciation in value of the optioned stock from the date of grant in
lieu of exercise of the stock options held.

     The Corporation continues to elect APB 25 for recognition of stock-based
compensation expense. However, under the provision of FAS 123 the Corporation is
required to estimate on the date of grant the fair value of each option using an
option-pricing model. Accordingly, the Black-Scholes option pricing model is
used with the following weighted-average assumptions for 1996 and 1995,
respectively: dividend yield of 4.5% for both years, expected volatility of
25.3% for both years, risk free interest rate of 6.34% and 6.20%, and

expected life of 8 years for both years. The following table summarizes
information about the stock-based compensation plan as of December 31, 1996 and
1995, and changes that occurred during the year:

NOTE 8  --  REINSURANCE AND OTHER CONTINGENCIES

In the normal course of business, the Corporation seeks to reduce the loss that
may arise from catastrophes or other events that cause unfavorable underwriting
results by reinsuring certain levels of risk with other insurers or reinsurers.
In the event that such reinsuring companies might be unable at some future date
to meet their obligations under the reinsurance agreements in force, the
Corporation would continue to have primary liability to policyholders for losses
incurred. The following amounts are reflected in the financial statements as a
result of reinsurance ceded:

     Annuities are purchased from other insurers to pay certain claim
settlements; should such insurers be unable to meet their obligations under the
annuity contracts, the Corporation would be liable to claimants for the
remaining amount of annuities. The total amount of unpaid annuities was $25,139,
$24,300 and $24,300 at December 31, 1996, 1995 and 1994, respectively.

     On October 2, 1995, as part of the transaction involving the reinsurance of
the Ohio Life business to Employers' Reassurance Corporation, Ohio Casualty
Insurance Company agreed to manage a $163,615 fixed income portfolio for
Employers' Reassurance. The term of the agreement is seven years, terminating on
October 2, 2002. There is no separate fee to Ohio Casualty for this investment
management service. The agreement requires that Ohio Casualty pay an annual rate
of 7.25% interest to Employers' Reassurance and maintain the market value of the
account at $163,615. In the event the market value falls below this amount, Ohio
Casualty is required to make up any deficiency. At the termination of the
contract, any excess over $163,615 is payable to Ohio Casualty. At December 31,
1996, the market value of the account exceeded the $163,615 required balance by
$699 compared with $2,497 in 1995 . The annual interest obligation of 7.25% was
also being adequately serviced by the portfolio assets.

NOTE 9  --  LOSSES AND LOSS RESERVES

The reserves for unpaid losses and loss adjustment expenses are based on
estimates of ultimate claim costs, including claims incurred but not reported,
salvage and subrogation and inflation without discounting. The methods of making
such estimates are continually reviewed and updated, and any resulting
adjustments are reflected in earnings currently.

</TABLE>

     The effect of catastrophes on the Corporation's results cannot be
accurately predicted. As such, severe weather patterns could have a material
adverse impact on the Corporation's results.

     Inflation has historically affected operating costs, premium revenues and
investment yields as business expenses have increased over time. The long term
effects of inflation are considered when estimating the ultimate liability for
losses and loss adjustment expenses. The liability is based on historical loss
development trends which are




<PAGE>   19

adjusted for anticipated changes in underwriting standards, policy provisions
and general economic trends. It is not adjusted to reflect the effect of
discounting.

     Reserves for asbestos-related illnesses and toxic waste cleanup claims
cannot be estimated with traditional loss reserving techniques. In establishing
liabilities for claims for asbestos-related illnesses and for toxic waste
cleanup claims, management considers facts currently known and the current state
of the law and coverage litigation. However, given the expansion of coverage and
liability by the courts and the legislatures in the past and the possibilities
of similar interpretations in the future, there is uncertainty regarding the
extent of remediation. Accordingly, additional liability could develop.
Estimated environmental case reserves of $13,579, $14,467 and $10,400 were
included in loss and loss adjustment expense reserves for 1996, 1995 and 1994,
respectively. In 1996, the Corporation analyzed incurred but not reported
reserves for general liability and commercial multiple peril to segregate
between asbestos and environmental losses and all other losses. As a result of
this analysis, $27,377 in incurred but not reported reserves were segregated as
asbestos and environmental related. This brings total asbestos and environmental
reserves as of December 31, 1996 to $40,956.

     A new investment accounting system was implemented in the fourth quarter of
1996. The new system more accurately accrues interest and calculates
amortization for mortgage-backed securities. As a result, investment income was
increased by $3,977. This adjustment represents a one-time positive impact on 
income.

     The Ohio Casualty Insurance Company, domiciled in Ohio, prepares its
statutory financial statements in accordance with the accounting practices
prescribed or permitted by the Ohio Insurance Department. Prescribed statutory
accounting practices include a variety of publications of the National
Association of Insurance Commissioners (NAIC), as well as state laws,
regulations, and general administrative rules. Permitted statutory accounting
practices encompass all accounting practices not so prescribed.

     The Company received written approval from the Ohio Insurance Department to
have the California Proposition 103 liability reported as a direct charge to
surplus and not included as a charge in the 1995 or 1994 statutory statement of
operations.

NOTE 13  --  BANK NOTE PAYABLE

In 1994, $70,000 was borrowed under a new credit facility to replace existing
debt. The new term loan has a final maturity in 2001 with equal semi-annual
installment payments of $5,000 beginning in April, 1995. On March 26, 1996, the
Corporation entered into an interest rate swap. The effect of the swap agreement
was to establish a fixed rate of 6.34% on one-half of the outstanding loan
balance. The remaining loan balance bears interest at a periodically adjustable
rate. The interest rate was 6.33% at December 31, 1996. The interest rate is
determined on various bases including prime rates, certificate of deposit rates
and the London Interbank Offered Rate. Interest incurred on borrowings amounted
to $3,769, $4,474 and $4,102 in 1996, 1995 and 1994, respectively.



<PAGE>   20

Under the loan agreement, statutory surplus is $484,859 in excess of the minimum
amount required to be maintained at December 31, 1996.

NOTE 14  --  CALIFORNIA WITHDRAWAL

As a result of the lack of profitability and the difficult regulatory
environment, the Corporation announced its intention to withdraw from business
operation in California on June 15, 1992. In December 1992, the Corporation
stopped writing business in California and filed a withdrawal plan with the
California Department of Insurance. Under the terms of the plan, subsidiary
American Fire and Casualty Company would wind down the affairs of the Group. In
November 1994, the California Department of Insurance published the required
notices of the withdrawal application. In April 1995, the California Department
of Insurance gave final approval for withdrawal, and the Corporation implemented
the withdrawal plan.

     Proposition 103 was passed in the State of California in 1988 in an attempt
to legislate premium rates for that state. Even after considering investment
income, total returns in California have been less than what would be considered
"fair" by any reasonable standard. During the fourth quarter of 1994, the State
of California billed the Corporation $59,867 for Proposition 103 assessment. In
February 1995, California revised this billing to $47,278 due to California
Senate Bill 905 which permits reduction of the rollback due to commissions and
premium taxes paid. The billing was revised again in August of 1995, and at
present, the State has indicated the Corporation should not be required to pay
in excess of $42,100 plus interest as a Proposition 103 assessment. As a result,
the Corporation's reserve for this alleged liability is $74,376.

     The Corporation is currently involved in hearings with the State of
California. The final arguments are expected to conclude in the first quarter of
1997. A ruling from the Administrative Law Judge is expected in the second
quarter of 1997. At that time the Insurance Commissioner will have 60 days to
take the ruling under advisement and return with his ruling. The Corporation
will continue to challenge the validity of any rollback and plans to continue
negotiations with Department officials. It is uncertain when this will
ultimately be resolved. To date, the Corporation has paid $2,889 in legal costs
related to the withdrawal, Proposition 103, and Fair Plan assessments.

NOTE 15  --  SHAREHOLDER RIGHTS PLAN

On December 15, 1989, the Board of Directors adopted a Shareholder Rights Plan
and declared a dividend of one Common Share Purchase Right expiring in 1999 for
each outstanding share of common stock. Each right entitles the registered
holder, under certain conditions, to purchase one share of common stock at a
price of $75, subject to adjustment at the time rights become exercisable if a
person or group acquires or announces its intention to acquire 20% or more of
the common stock of the Corporation without the prior approval of the Board of
Directors. The rights may be redeemed for one cent per right at any time prior
to becoming exercisable.

NOTE 16  --  STOCK SPLIT

On February 17, 1994, the Board of Directors declared a stock split in which one
share was distributed for each share outstanding. This 2 for 1 split pertained
to shareholders of record on April 1, 1994. The result of the stock split
increased issued shares from 23,401,936 to 46,803,872. All per share information

Discontinued operations include the operations of Ohio Life, a subsidiary of the
Ohio Casualty Insurance Company. 

     On October 2, 1995, the Company transferred its life insurance and related
businesses through a 100% coinsurance arrangement to Employers' Reassurance
Corporation and entered into an administrative and marketing agreement with
Great Southern Life Insurance Company. In connection with the reinsurance
agreement, $144,469 in cash and $161,401 of securities were transferred to
Employers' Reassurance to cover the liabilities of $348,479. Ohio Life received
an adjusted ceding commission of $37,641 as payment. After deduction of deferred
acquisition costs, the net ceding commission from the transaction was $17,284.
As of December 31, 1996, $12,918 of that gain remains unamortized. This balance
will be amortized over 14 years, the remaining expected life of the underlying
reinsured policies. It is anticipated that Great Southern will replace Ohio Life
as the primary carrier of these policies in the second quarter of 1997 through
an assumption. At that time, the remaining unamortized gain will be recognized.

     Results of the discontinued life insurance operations for the years ended
December 31 were as follows:

                         ANNUAL MEETING OF SHAREHOLDERS
                   APPROXIMATE DATE TO MAIL -- MARCH 14, 1997
 
     On behalf of the Board of Directors of Ohio Casualty Corporation (the
"Company"), a proxy is solicited from you to be used at the Company's 1997
Annual Meeting of Shareholders (the "Annual Meeting") scheduled for Wednesday,
April 16, 1997 at 10:30 a.m., local time, in the meeting rooms of The
Hamiltonian Hotel, One Riverfront Plaza, Hamilton, Ohio 45011, or at any
adjournment thereof.
 
     Proxies in the form enclosed herewith are being solicited on behalf of the
Company's Board of Directors. The common shares represented by proxies which are
properly executed and returned will be voted at the Annual Meeting, or any
adjournment thereof, as directed. Common shares represented by proxies properly
executed and returned which indicate no direction will be voted in favor of the
nominees of the Board of Directors identified in the Notice of Annual Meeting
accompanying this Proxy Statement and for the adoption of the proposed
amendments to the Company's 1993 Stock Incentive Program. Any shareholder giving
the enclosed proxy has the power to revoke the same prior to its exercise by
filing with the Secretary of the Company a written revocation or duly executed
proxy bearing a later date, or by giving notice of revocation in open meeting.
ATTENDANCE AT THE ANNUAL MEETING WILL NOT, IN AND OF ITSELF, CONSTITUTE
REVOCATION OF A PROXY.
 
                            VOTING AT ANNUAL MEETING
 
     As of March 3, 1997, the record date fixed for the determination of
shareholders entitled to notice of and to vote at the Annual Meeting, there were
outstanding 35,110,231 common shares, which is the only outstanding class of
capital stock of the Company. Each such common share is entitled to one vote on
all matters properly coming before the Annual Meeting.
 
     A quorum for the Annual Meeting is a majority of the outstanding common
shares. Common shares represented by signed proxies that are returned to the
Company will be counted toward the quorum in all matters even though they are
marked "Abstain", "Against" or "Withhold Authority" on one or more or all
matters or they are not marked at all. Broker non-votes are also counted for
purposes of determining the presence or absence of a quorum. Broker non-votes
occur when brokers, who hold their customers' shares in street name, sign and
submit proxies for such shares on some matters, but not others. Typically, this
would occur when brokers have not received any instructions from their
customers, in which case the brokers, as the holders of record, are permitted to
vote on "routine" matters, which typically include the election of directors,
but not on non-routine matters.

     On May 21, 1996, Arthur J. Bennert and Catherine E. Dolan, each of whom is
a non-employee director of the Company, were granted a non-qualified stock
option (an "NQSO") to purchase 3,000 common shares of the Company at an exercise

who becomes or is re-elected a non-employee director is automatically granted an
NQSO to purchase 3,000 common shares effective on the third business day

years (subject to earlier termination in certain cases) and may not be exercised
during the six months following their date of grant.

    Committee Report on Executive Compensation). Shares of restricted stock were
    granted on February 20, 1997 to certain of the named executive officers
    pursuant to the Plan for services rendered in 1996. Such restricted common
    shares vest on the third anniversary of the date of grant so long as the
    executive officer is an employee on such date (with earlier vesting
    occurring on retirement, death or disability or termination of employment
    following a change of control). Dividends are paid on restricted common
    shares at the same rate as paid on the Company's common shares. No
    restricted common shares were outstanding at the end of 1996.
 
(6) Dividend payment rights were granted to the named executive officers in
    1996. One third of these rights become effective on each anniversary of the
    grant date. These rights entitle to the holder on the April 15th following
    the fourth anniversary of the grant date to receive, for each dividend
    payment right, an amount in cash equal to the aggregate amount of dividends
    that the Company has paid on each common share from the date on which such
    right becomes effective through the payout date subject to certain
    restrictions.
 
(7) Mr. Fogarty retired as executive officer of the Company effective January 1,

(1) All of these stock options, which were granted pursuant to the Ohio Casualty
    Corporation 1993 Stock Incentive Program, were granted at market value on
    the date of grant, become exercisable as to one-third of the option shares
    on each of the first three anniversaries of the date of grant and have a
    term of ten years. In the event of a change in control of the Company, the
    stock options would become exercisable in full. Stock options reported
    consist of incentive stock options and non-qualified stock options.
 
(2) The dollar amounts under these columns are the result of calculations at the
    5% and 10% annual appreciation rates set by the Securities Exchange
    Commission for illustrative purposes, and, therefore, are not intended to
    forecast future financial performance or possible future appreciation in the
    price of the Company's common shares. Shareholders are therefore cautioned
    against drawing any conclusions from the appreciation data shown, aside from
    the fact that optionees will only realize value from the option grants shown
    when the price of the Company's common shares appreciates, which benefits
    all shareholders commensurately.

     Retirement benefits under the Company's Employees Retirement Plan, a
defined benefit plan qualified under Section 401(a) of the Internal Revenue Code
of 1986, as amended (the "Code"), are generally payable to full-time and regular
part-time salaried employees whose participation in the plan has vested
(currently requiring the completion of five years of service) upon retirement at
age 65 or in reduced amounts upon retirement prior to age 65 if the participant
has ten years of vested service. A retiree's benefit amount is based upon his or
her credited years of service and average annual compensation (salary) for the
five consecutive years of highest salary during the last ten years of service
immediately prior to age 65 or, if greater, the average annual compensation paid
during the 60 consecutive month period immediately preceding retirement or other
termination of employment. Such retirement benefits are reduced by a portion of
the retiree's Social Security-covered compensation. Benefits figures shown in
the table above are computed on the assumption that participants retire at age
65 and are entitled to a single life annuity.
 
     Section 401(a)(17) of the Code prohibits compensation in excess of $150,000
($160,000 for 1997) from being taken into account in determining benefits
payable under a qualified pension plan. As a result, the Benefit Equalization
Plan was adopted for those employees who are adversely affected by these
provisions of the Code. The Benefit Equalization Plan provides for payment of
benefits that would have been payable under the Employees Retirement Plan but
for the limitation on compensation imposed by the Code. Upon retirement,
participants receive the actuarial equivalent present value of the benefit
payable under the Benefit Equalization Plan in a lump sum.
 
     At December 31, 1996, credited years of service and average annual earnings
under the Employees Retirement Plan and the Benefit Equalization Plan for the
executive officers named in the Summary Compensation Table were: Lauren N.
Patch, 20.5 years ($372,046); Barry S. Porter, 22.5 years ($210,852); Andrew T.
Fogarty, 24.5 years ($231,569); Jeffery D. Lowe, 21.5 years ($194,475); and
Michael L. Evans, 21.5 years ($148,778). The compensation covered by the
Employees Retirement Plan and the Benefit Equalization Plan is the amount shown
in the Summary Compensation Table as salary, less any directors' fees.
 
                    EXECUTIVE COMPENSATION COMMITTEE REPORT
                           ON EXECUTIVE COMPENSATION
 
EXECUTIVE COMPENSATION POLICIES
 
     The Company's executive compensation programs are designed to enable it to
recruit, retain and motivate outstanding executives. This is essential for the
Company to achieve its challenging performance objectives and to achieve
superior investment returns for its shareholders.
 
     The Committee believes that the Company's executive compensation
opportunities, including those for the Company's Chief Executive Officer
("CEO"), should create incentives for superior performance and consequences for
below-target performance. In 1996, the Company's Board of Directors approved a
redesigned executive compensation program which more closely links the level of
executive compensation with Company performance. A substantial portion of each
executive's compensation potential is now tied to achievement of annual
objectives and long-term shareholder returns. An important consideration in the
design of the new executive compensation program was the use of Company shares
to encourage greater share ownership by Company executives so that the
opportunity of the Company's executives for financial gain is directly linked to
increases in shareholder wealth, as reflected by the market price of the
Company's common shares. This redesigned executive compensation program was
first implemented during the 1996 fiscal year.
 
     The Company's basic compensation program for its executive officers and
approximately 17 additional key executives (collectively called the "Partners")
consists of the following ele-
 
                                       10
<PAGE>   12
 
ments: (i) base salary established on an annual basis, (ii) an Annual Incentive
Plan whereby annual awards, payable in the form of restricted common shares, may
be made to the Partners based on individual and team performance with team
performance being measured generally by the Company's total return performance
as measured against predetermined return on equity (ROE) goals; and (iii) a
Long-Term Incentive Plan whereby stock options and dividend payment rights are
awarded on an annual basis. As described more fully below, each element of the
Company's executive compensation program has a somewhat different purpose. Stock
options and restricted shares are issued under the shareholder-approved 1993
Stock Incentive Program.
 
     As part of the administration of the Company's new executive compensation
program, the Committee will annually examine short-term and long-term
compensation levels for the CEO and other senior executives against a survey of
the compensation practices of comparably sized property and casualty insurance
companies (the "survey companies"). The survey companies include some, but not
all, of the companies covered in the Dow Jones Insurance Index for Property and
Casualty Companies included in the Performance Graph on page 14.
 
SPECIFIC COMPENSATION PROGRAMS
 
     Base salary ranges for the CEO and the other executive officers of the
Company are based on individual performance, the responsibilities associated
with an individual's position and the skills and experience of the individual,
which are reviewed annually and benchmarked against similar positions among the
survey companies. Salary ranges are targeted at the median level for similar
positions among the survey companies. The base salary of the CEO is established
by the Committee. The base salaries of the other executive officers are
established by the CEO. Salary adjustments are evaluated on an annual basis and
are based on individual performance, as determined in accordance with the
Company's executive performance evaluation system, and as reflective of
competitive conditions existing at the time.
 
     The Company's Annual Incentive Plan and its Long Term Incentive Plan are
designed to provide participants with the opportunity to receive total
compensation targeted at 75th percentile of salaries for similar positions among
the survey companies.
 
     The potential award opportunities for each of the executives who
participate in the Annual Incentive Plan are determined at the beginning of such
year by the Committee for the executive officers, including the CEO, and by the
CEO for all other Partners. Potential award opportunities for a fiscal year,
which are expressed as a percentage of a participant's base salary for the
fiscal year, are based on a participant's position in the Company's management
organization, with higher percentages being assigned to executives who hold more
senior positions. Actual award amounts are based on a combination of team
performance and individual performance. Team performance, which accounts for up
to 50% of the total award potential, is based on the Company's actual
performance against pre-determined return on equity and premium growth goals for
the year. If the Company does not meet the established threshold performance
level, no team awards are made. If the threshold performance is achieved, each
of the executive officers and other Partners receives a team award, the amount
of which depends on the extent to which the Company's performance exceeds the
threshold level and the potential award opportunity assigned to each individual
participant, as described above. Individual awards are made only if the
performance level required for team awards has been met and then only if a
determination is made by the Committee and CEO to fund such awards. The
Committee determines, based on a recommendation from the CEO, the level of
funding for the individual award pool based on the performance achieved by the
management team on a number of criteria. The pool is allocated among the
participants on the basis of their performance evaluations as determined by the
CEO (the CEO's performance evaluation is conducted by the Committee). Individual
performance accounts for the remaining 50% of the total award potential under
the Annual Incentive Plan.
 
                                       11
<PAGE>   13
 
     Awards under the Annual Incentive Plan are paid in restricted shares of the
Company. The Company also pays the taxable income resulting to the participant
from the grant. Such restricted stock shares may not be transferred by the
participant for a three-year period following the date of grant, unless the
participant dies or his employment is terminated as a result of disability or
retirement or following a change in control of the Company. If the employment of
the participant terminates for any other reason during such three-year period,
the restricted shares will be forfeited to the Company. The Committee believes
that restricted shares provide a strong incentive for executives to continue as
employees of the Company and to work to increase the value of the Company during
their employment. Awards under the Annual Incentive Plan for 1996 were paid in
the form of restricted common shares issued in February of 1997.
 
     Awards under the Company's Long-Term Incentive Plan consist of stock
options, either incentive stock options or non-qualified stock options, and
dividend payment rights. Stock options are granted at market value on the date
of grant and increase in value only to the extent of appreciation in the
Company's common shares. The stock options become exercisable over a period of
three years and expire at the end of ten years from the date of grant. Stock
option grants are made at the beginning of each year, although grants may be
made at different times to participants who are promoted or newly hired. The
number of stock options to be granted annually to an individual participant over
a three-year period is based on the participant's salary level and position.
While it is the intention of the Committee to make stock options grants
annually, the Committee has reserved the right to eliminate stock option awards
or make other modifications in the Long-Term Incentive Plan. The Committee also
intends to hold constant the number of shares granted to each participant over
each three-year period, although it has reserved the right to make changes in
the number of shares granted to any participant.
 
     In addition to stock options, participants in the Long-Term Incentive Plan
may be granted dividend payment rights. These rights, which become effective
over a three-year period, entitle the holder on the scheduled payout date to
receive, for each right, an amount in cash equal to the aggregate amount of
dividends that the Company has paid on each common share from the date on which
the dividend payment right becomes effective through the payout date. If the
holder ceases to be an employee prior to the payout date as a result of death,
disability, retirement or as a result of termination following change in control
of the Company, the Company will pay, for each dividend payment right which is
effective on the termination date, a cash amount equal to the aggregate amount
of dividends that the Company has paid on each Common Share from the date on
which the dividend payment right became effective through the termination date.
If the employment of the holder terminates for any other reason, the holder will
not be entitled to any payment whatsoever under this agreement. The employees to
whom stock options and dividend payment rights are to be awarded are determined
annually by the Committee for the executive officers, including the CEO, and by
the CEO for all other Partners.
 
     Section 162(m) of the Code generally limits the corporate tax deduction for
compensation paid to executive officers named in the Summary Compensation Table
in the proxy statement to $1 million, unless certain requirements are met. None
of the executive officers of the Company exceeded the threshold for
deductibility under Section 162(m) in 1996.
 
BASES FOR CHIEF EXECUTIVE OFFICER COMPENSATION
 
     The Committee evaluates the performance of the CEO at least annually. In
1996, Mr. Patch received a base salary of $505,000, which represented a 12.2%
increase over his base salary for 1995. The Committee's decision to increase Mr.
Patch's base salary was based on its evaluation of his performance and its
current policy that the salaries for the Company's executive officers, including
Mr. Patch, should be set at the median level for CEO's of the survey companies.
Mr. Patch also received an award under the Annual Incentive Plan for service in
1996 of a total of 1,399 restricted common shares of the Company, which were
issued to him in 1997 and which
 
                                       12
<PAGE>   14
 
will be forfeited to the Company if he leaves the Company during the three-year
period following the date of issue. As described in detail above, the
Committee's determination of the number of restricted common shares awarded to
Mr. Patch (and to all of the other executive officers) under the Annual
Incentive Plan was based on the Company's 1996 total return performance as
measured against an established return on equity target. No individual awards
were made to any of the Company's executive officers under the Annual Incentive
Plan for 1996. The Company also granted to Mr. Patch in 1996 pursuant to the
Long-Term Incentive Plan an incentive stock option for 8,571 shares and a
non-qualified stock option for 21,429 shares. The number of stock options
granted to Mr. Patch was based on his salary level and position with the
Company. As previously indicated, in establishing the compensation of Mr. Patch
and the other executive officers, the goal of the Committee has been to create a
total compensation opportunity through base salary and awards under the Annual
Incentive Plan and the Long-Term Incentive Plan which, if realized as a result
of the Company's performance, would result in total compensation being at the
75th percentile for similar positions at the survey companies.

               PROPOSED AMENDMENT TO 1993 STOCK INCENTIVE PROGRAM
 
     The Company's 1993 Stock Incentive Program, which was approved by the
shareholders of the Company at the 1993 Annual Meeting of Shareholders, provides
for the issuance of incentive stock options ("ISOs"), nonqualified stock options
("NQSOs") (ISOs and NQSOs are herein referred to together as "Stock Options"),
stock appreciation rights ("SARs"), limited stock appreciation rights ("LSARs")
and restricted stock awards (collectively, "Awards").
 
     The purpose of the 1993 Program is to attract and retain outstanding
individuals as directors, officers and other key employees of the Company and
its subsidiaries and to furnish incentives to such persons by providing them
opportunities to acquire common shares of the Company on advantageous terms.
 
     The 1993 Program is administered by the Executive Compensation Committee of
the Board of Directors of the Company (the "Committee"). Officers and other
full-time, salaried employees of the Company and its subsidiaries (including the
persons identified in the Summary Compensation Table on page   ) who are
selected by the Committee are eligible to receive Stock Options and other Awards
under the 1993 Program. Directors of the Company who are not full-time employees
of the Company or its subsidiaries ("Non-Employee Directors") are participants
in
 
                                       14
<PAGE>   16
 
the 1993 Program solely for purposes of receiving certain NQSO Awards. See
"Stock Option Grant to Non-Employee Directors."
 
     The 1993 Program currently authorizes the granting of Stock Options and
other Awards for a total of 1,000,000 common shares and an additional 293,500
common shares of the Company from the prior plan, subject to adjustment to
reflect certain corporate events, including stock splits. As of the date of this
Proxy Statement, a total of 1,006,320 common shares were available for future
grants of Stock Options and other Awards. As of March 3, 1997, ISOs to purchase
an aggregate of 118,284 common shares were outstanding and held by 18 employees,
including executive officers; NQSOs to purchase an aggregate of 133,716 common
shares were outstanding and held by 4 employees, including executive officers
and 9 Non-Employee Directors; and restricted stock awards for a total of 5,579
common shares were outstanding and held by 18 executive officers. It is
estimated that a total of 60 employees of the Company and its subsidiaries and 9
Non-Employee Directors are currently eligible to participate in the 1993
Program.
 
DESCRIPTION OF AMENDMENTS
 
     On February 20, 1997, the Board of Directors of the Company adopted,
effective upon shareholder approval at the Annual Meeting, the following
amendments to the 1993 Program (the "Amendments"):
 
          1. For purposes of satisfying the requirements of Section 162(m) of
     the Internal Revenue Code of 1986, as amended (the "Code"), the 1993
     Program has been amended, subject to shareholder approval, to (i) provide
     that no participant may be granted Stock Options and other Awards for more
     than 75,000 common shares during any 12-month period, and (ii) to clarify
     that members of the Committee must satisfy the requirements of "outside
     directors" as such term is described in the Code and accompanying
     regulations of the Internal Revenue Service. In addition, the 1993 Program
     has been amended, subject to shareholder approval, to provide that the
     Committee shall be comprised of directors who are "Non-Employee Directors"
     as that term is defined in Rule 16b-3(b) promulgated by the Securities and
     Exchange Commission under the Securities Exchange Act of 1934, as amended
     (the "1934 Act").
 
          2. The 1993 Program has been amended, subject to shareholder approval,
     to permit the Company to grant Stand Alone Stock Appreciation Rights which
     may be granted without reference to any stock option granted under the 1993
     Program ("Stand Alone Stock Appreciation Rights"). Previous to such
     amendment, upon exercise of SARs granted pursuant to the 1993 Program, the
     holder must surrender a related stock option for the number of SARs being
     exercised. Stand Alone Stock Appreciation Rights may be exercised by a
     holder without having to surrender a stock option or any portion thereof.
 
          3. The 1993 Program has also been amended, subject to shareholder
     approval, to clarify the circumstances under which Non-Employee Directors
     are entitled to receive NQSOs. The Committee has interpreted the language
     of the 1993 Program as providing for the grant of a NQSO to each
     Non-Employee Director on the third business day following the first meeting
     of the Board of Directors after his or her election or appointment to the
     Board and on the third business day following re-election to the Board by
     the shareholders. The proposed Amendment to the 1993 Program is intended to
     clarify and confirm such interpretation of the Committee.
 
     The Amendments will become effective as of February 20, 1997, the date of
approval of the Amendments by the Board of Directors, if a majority of the
common shares of the Company, present in person, or by proxy at the Annual
Meeting is voted in favor of the Amendments. The closing price of the Company's
common shares as reported in the NASDAQ National Market
 
                                       15
<PAGE>   17
 
System on March 3, 1997 (record date for the Annual Meeting) was $39.50 per
share. The Amendments are discussed in greater detail below.
 
OPERATION OF THE 1993 PROGRAM
 
     There follows a summary of the 1993 Program. This summary is qualified in
its entirety by reference to the copy of the 1993 Program, as amended, attached
to this Proxy Statement as Exhibit A.
 
SHARES AVAILABLE UNDER THE 1993 PROGRAM
 
     Common shares issued pursuant to the 1993 Program may be either authorized
and unissued common shares or treasury shares. If there is a lapse, expiration,
termination or cancellation of any Stock Option or Award without the issuance of
common shares or payment of cash thereunder, or if common shares are issued
under any Award and thereafter are reacquired by the Company pursuant to rights
reserved upon the issuance thereof, in each case so long as the holder thereof
has not received any benefits of ownership of such common shares, the common
shares subject to or reserved for such Stock Option, or other Award may again be
used for new Stock Options or other authorized Awards under the 1993 Program.
 
     In the event of the exercise of an SAR or an LSAR, the number of common
shares reserved for issuance under the 1993 Program will be reduced by the
number of common shares covered by the Stock Option or portion thereof which is
surrendered in connection with such exercise. If the Amendments are adopted and
Stand Alone Stock Appreciation Rights are authorized the exercise of Stand Alone
Stock Appreciation Rights will also reduce the number of common shares reserved
for issuance under the 1993 Program by the number of Stand Alone Stock
Appreciation Rights being exercised.
 
ADMINISTRATION
 
     The 1993 Program is administered by the Committee. The Committee has
complete discretion to select the individuals to whom Stock Options and other
Awards are granted (other than Non-Employee Directors) and to establish the
terms and conditions of each such grant, subject in each case to the provisions
of the Program. In addition, the Committee is empowered to interpret the 1993
Program and make all determinations necessary or advisable for its
administration. Presently, the members of the Committee are Messrs. Vaden
Fitton, Jack E. Brown, and Stanley N. Pontius.
 
     Section 162(m) of the Code prohibits a publicly held corporation, such as
the Company, from claiming a deduction on its federal income tax return for
compensation in excess of $1 million paid for a given fiscal year to the chief
executive officer (or person acting in that capacity) at the close of the
corporation's fiscal year or any of the four most highly compensated officers of
the corporation, other than the chief executive officer, at the end of the
corporation's fiscal year. The $1 million compensation deduction limitation does
not apply to "performance-based compensation." The regulations issued by the
Internal Revenue Service under Section 162(m) (the "IRS Regulations") set forth
a number of provisions which compensatory plans, such as the 1993 Program, must
contain if Stock Options issued under such plans are to qualify as
performance-based for the purposes of Section 162(m).
 
     One of the Amendments that is necessary in order that the 1993 Program will
satisfy the requirements for performance based compensation set forth in the IRS
Regulation relates to the composition of the Committee. If the Amendments are
adopted by the shareholders, each member of the Committee will be required to be
an "outside director" as that term is used in the Code and the accompanying
regulations of the Code. The Amendments will also require that the Committee be
comprised of persons who satisfy the requirements of a "Non-Employee Director"
as that term is defined in newly-amended Rule 16b-3(b) under the 1934 Act. Rule
16b-3
 
                                       16
<PAGE>   18
 
provides for an exemption from the short-swing profits recapture provisions of
Section 16(b) of the 1934 Act for certain transactions between an issuer and its
officers or directors involving shares of the issuer.
 
ELIGIBILITY
 
     Officers and other full-time, salaried employees of the Company and its
subsidiaries (including the persons named in the Summary Compensation Table on
page 7) who are selected by the Committee are eligible to receive Stock Options
and other Awards. Non-Employee Directors are participants in the 1993 Program
solely for purposes of receiving certain NQSO awards. There are currently 9
Non-Employee Directors of the Company.
 
     A second amendment of the 1993 Program that is necessary in order that the
1993 Program will satisfy the requirements of the IRS Regulations, for Stock
Options under Section 162(m) of the Code relates to the maximum number of common
shares which can be allocated to any one person under the 1993 Program. The 1993
Program originally included no limit on the number of common shares that could
be allocated to any one person, other than the limits imposed on common shares
covered by NQSO awards granted to Non-Employee Directors. The Amendments provide
that no participant may be granted Stock Options and other Awards for more than
75,000 common shares during any calendar year.
 
     As described in the Executive Compensation Committee Report on Executive
Compensation, grants of stock options and restricted common shares under the
1993 Program are significant elements of the Company's executive compensation
program. The following table sets forth the number and exercise price of Stock
Options and restricted common shares granted and issued during 1996 and 1997
(through the date of this Proxy Statement) under the 1993 Program to (1) each of
the executive officers of the Company named in the Summary Compensation Table,
(ii) all current executive officers of the Company as a group, (iii) all current
directors who are not executive officers as a group and (iv) all employees,
including all current officers who are not executive officers, as a group. None
of the nominees for election as director who is not an executive officer
received stock options or other awards in 1996 or 1997 (through the date of this
proxy statement). No Stock Options or other Awards have been granted to
associates of any of the directors or executive officers, and other than the
persons identified in the following table,
 
                                       17

no person received five percent or more of the Stock Options or restricted
shares granted under the 1993 Program during 1996 or 1997.

(1) No restricted shares were granted in 1996. Information concerning the
    restricted shares awarded in 1997 appears in the Summary Compensation Table
    for 1996 because these restricted shares were granted in connection with
    services rendered in 1996.
 
(2) As discussed in the Report of the Executive Compensation Committee, it is
    anticipated that a similar number of Stock Options will be granted under the
    1993 Program to executive officers in 1998.
 
(3) See Report of the Executive Compensation Committee for discussion of
    restricted share awards.
 
DURATION
 
     Any grant of a Stock Option or other Award must be made within ten years
after the date the 1993 Program was adopted by the Company's Board of Directors
(February 18, 1993).
 
ADJUSTMENTS
 
     The 1993 Program provides for adjustment in the number of common shares
reserved for issuance under the 1993 Program, the maximum number of common
shares which may be sold or awarded to any participant and the number and
exercise or purchase price of common shares covered by each outstanding Stock
Option or other Award in the event of a stock dividend, stock split or other
change in the Company's capitalization affecting its common shares and for
adjustment of Stock Options or other Awards in the event of changes in the
common shares resulting from reorganization, sale, merger, consolidation or
similar occurrence.
 
TERMS OF AWARDS
 
     Stock Options.  The option exercise price of any Stock Option granted under
the 1993 Program may not be less than 100% of the Fair Market Value of the
Common shares on the date of grant. In the case of any Stock Option, Fair Market
Value is defined as the closing price of the Company's common shares on the
relevant date, as reported in the NASDAQ National Market System. The period
during which any Stock Option may be exercised is determined by the
 
                                       18
<PAGE>   20
 
Committee, but no Stock Option may be exercised after the expiration of ten
years from the date it is granted.
 
     Under the 1993 Program, no employee may receive an ISO if, at the time of
grant, such employee owns of record or beneficially more than 10% of the total
combined voting power of all classes of stock of the Company or of any
subsidiary of the Company unless the option exercise price is at least 110% of
the Fair Market Value of the common shares covered by the ISO on the date of
grant and the option term does not exceed five years. The 1993 Program provides
that the aggregate fair market value (determined as of the time as ISO is
granted) of the common shares with respect to which ISOs may become exercisable
for the first time by any individual during any calendar year (under all option
plans of the Company and its subsidiary corporations) may not exceed $100,000.
 
     The Committee may provide for the payment of the option exercise price of
common shares under a Stock Option in cash, by delivery of other common shares
of the Company having a Fair Market Value equal to the option exercise price of
such shares, or by delivery of an exercise notice accompanied by a copy of
irrevocable instructions to a broker to deliver promptly to the Company sale or
loan proceeds to pay the option exercise price. A Stock Option may be exercised
only after six months from its grant date. The 1993 Program contains special
rules governing the time of exercise of Stock Options and SARs in cases of
retirement, death, disability, or other termination of employment. The 1993
Program also provides that, upon the occurrence of a "Change in Control" (as
defined in the 1993 Program) of the Company, all Stock Options, SARs, Stand
Alone Stock Appreciation Rights and LSARs which have been outstanding for at
least six months (whether or not then exercisable) will become fully exercisable
as of the date of the Change in Control.
 
     SARs.  An SAR permits the holder to elect to surrender any related Stock
Option or portion thereof which is then exercisable and to receive in exchange
therefor cash in an amount equal to the excess of the Fair Market Value on the
date of such election of one common share over the option exercise price
multiplied by the number of common shares covered by the Stock Option or portion
thereof which is surrendered. The Committee has the discretion to satisfy the
right of a holder of an SAR to receive cash upon the exercise of an SAR, in
whole or in part, by the delivery of common shares. For purposes of an SAR, Fair
Market Value is defined as the closing price of the Company's common shares on
the date of grant.
 
     SARs may be granted with respect to a Stock Option at the time of its grant
or at any time thereafter up to six months prior to its expiration. An SAR may
be granted to an employee regardless of whether such employee has been granted
an LSAR (as described below) with respect to the same Stock Option, although an
SAR may not be exercised during any period that an LSAR with respect to the same
Stock Option may be exercised. An SAR may be exercised only after six months
from its grant date. An SAR will be exercisable upon such additional terms and
conditions as may be prescribed by the Committee in its sole discretion, but in
no event will it be exercisable after the expiration of the related Stock
Option.
 
     LSARs.  The 1993 Program also permits the grant of LSARs to the holder of
any Stock Option at the time of the grant of the Stock Option or at any time
thereafter up to six months prior to its expiration. An LSAR may be granted to
an employee regardless of whether such employee has been granted an SAR with
respect to the same Stock Option. An LSAR will permit the holder to surrender
the related Stock Option or portion thereof which is then exercisable and
receive in exchange therefor cash in an amount equal to the excess of the Fair
Market Value on the date of such election of one common share over the option
exercise price multiplied by the number of common shares covered by the Stock
Option or portion thereof which is surrendered. An LSAR may be exercised only
after six months from its date of grant and only during the sixty-day period
commencing with the day following the date of a Change in Control of the
Company. In the case of an LSAR (other than an LSAR related to an ISO), Fair
Market Value is
 
                                       19
<PAGE>   21
 
the higher of (i) the highest daily closing price of the Common Shares during
the sixty-day period following the Change in Control or (ii) the highest price
paid for Common Shares by the acquirer in the Change in Control. In addition, an
LSAR will be exercisable upon such additional terms and conditions as may be
prescribed by the Committee, in its sole discretion, but in no event will an
LSAR be exercisable after the expiration of the related Stock Option.
 
     Restricted Stock.  Restricted stock awards consist of common shares
transferred to participants, without other payment therefor (other than the
payment of the par value of such common shares if required by applicable law),
as additional compensation for their services to the Company or one of its
subsidiaries. Restricted stock awards will be subject to such terms and
conditions as the Committee determines appropriate including, without
limitation, restrictions on the sale or other disposition of such common shares
and rights of the Company to acquire such common shares upon termination of the
participant's employment within specified periods. Subject to such other
restrictions as are imposed by the Committee, the common shares covered by a
restricted stock award may be sold or otherwise disposed of only after six
months from the grant date of the award.
 
     Stand Alone Stock Appreciation Rights.  If the Amendments are adopted by
the shareholders, the 1993 Program will authorize the grant of Stand Alone Stock
Appreciation Rights. Unlike SARs and LSARs, Stand Alone Stock Appreciation
Rights may be granted without reference to any Stock Option granted under the
1993 Program. Thus, when a Stand Alone Stock Appreciation Right is exercised,
the holder is not required to surrender any related Stock Option or portion
thereof. Upon exercise of a Stand Alone Stock Appreciation Right, the holder
will receive cash (or, at the election of the Committee, common shares) in an
amount (or, in the case of common shares, having a Fair Market Value) equal to
the excess of the Fair Market Value on the date of election of one common share
over the exercise price of the right multiplied by the number of Stand Alone
Stock Appreciation Rights being exercised. For purposes of the Stand Alone Stock
Appreciation Rights, Fair Market Value is defined as the closing price of the
common shares as reported in the NASDAQ National Market System on the date of
grant. Stand Alone Stock Appreciation Rights may not be exercised during the six
months following the date of grant. The Amendments contain special rules
governing the time of exercise of Stand Alone Stock Appreciation Rights in case
of death or other termination of employment.
 
     Stock Option Grants to Non-Employee Directors.  The 1993 Program also
provides that each person who becomes a Non-Employee Director of the Company is
automatically granted an NQSO to purchase 3,000 common shares (reflects
adjustment for a two-for-one stock split in 1994) effective on the third
business day following the first meeting of the Board of Directors after
election or appointment to the Board. The option exercise price of each NQSO
granted to a Non-Employee Director is equal to the Fair Market Value of the
common shares on the date of grant.
 
     The Committee has interpreted the language of the 1993 Program as providing
for the grant of a NQSO to a Non-Employee Director following his or her initial
election or appointment to the Board of Directors and following each subsequent
annual meeting of shareholders at which he or she is re-elected to the Board of
Directors. The Amendments clarify the language of the 1993 Program to provide
for the grant of a NQSO to a Non-Employee Director on the third business day
following the date of his or her first election or appointment to the Board of
Directors and on the third business day following each Annual Meeting of
Shareholders at which he or she is elected or re-elected to the Board of
Directors for an additional term of office by the shareholders of the Company.
 
     NQSOs granted to Non-Employee Directors have terms of ten years. The 1993
Program contains special rules governing the time of exercise of NQSOs granted
to Non-Employee Directors in case of death, disability or other termination of
service as a director. Stock Options
 
                                       20
<PAGE>   22
 
granted to Non-Employee Directors may not be exercised during the six months
following their date of grant.
 
     Each Stock Option, SAR, LSAR, Stand Alone Stock Appreciation Right and
restricted stock award granted under the 1993 Program will not be transferable
other than by will or the laws of descent and distribution, and will be
exercisable, during a participant's lifetime, only by the participant or the
participant's guardian or legal representative.
 
AMENDMENTS AND DISCONTINUANCE
 
     The Board of Directors may amend the 1993 Program from time to time or
terminate the 1993 Program at any time without the approval of the shareholders
of the Company except as such shareholder approval may be required (a) to
satisfy the requirements of Rule 16b-3 under the Securities Exchange Act of
1934, (b) to satisfy applicable tax law requirements or (c) to satisfy
applicable requirements of the NASDAQ National Market System. No such action
may, without the consent of the participant, reduce the amount of any existing
Award of such participant or adversely change the terms and conditions thereof.
The provisions of the 1993 Program governing grants of NQSOs to Non-Employee
Directors may not be amended more frequently than once every six months other
than to comport with changes in the Code, or the rules thereunder or changes in
the Employee Retirement Income Security Act of 1974.
 
     The terms and conditions applicable to any Awards granted and outstanding
may at any time be amended, modified, or canceled, without shareholder approval,
by mutual agreement between the Committee and the participant so long as
shareholder approval of such amendment, modification or cancellation is not
required to permit the 1993 Program to satisfy the requirements of Rule 16b-3,
to satisfy applicable provisions of the tax laws or to satisfy any applicable
requirements of the NASDAQ National Market System. The Committee may, at any
time and in its sole discretion, declare any or all Stock Options (other than
any NQSO granted to a Non-Employee Director), SARs, Stand Alone Stock
Appreciation Rights and LSARs then outstanding under the 1993 Program to be
exercisable, and any or all outstanding restricted stock awards to be vested,
whether or not such Stock Options, SARs, Stand Alone Stock Appreciation Rights,
LSARs or other Awards are otherwise exercisable or vested.
 
FEDERAL INCOME TAX CONSEQUENCES
 
     Based on current provisions of the Code and the existing regulations
thereunder, the anticipated federal income tax consequences in respect of Stock
Options and other Awards granted under the 1993 Program are as described below.
The following discussion is not intended to be a complete statement of
applicable law and is based upon the federal income tax laws as in effect on the
date hereof. Since tax law is subject to change and since the application of tax
law may vary depending upon the facts applicable to the taxpayer, each
participant in the 1993 Program will be advised to consult with such
Participant's own tax advisor before taking action with respect to benefits
awarded to him or her under the 1993 Program.
 
ISOS
 
     In general, a participant who is granted an ISO does not recognize taxable
income either on the date of grant or on the date of exercise. However, upon the
exercise of the ISO, the difference between the Fair Market Value of the common
shares received and the option price is a tax preference item potentially
subject to the alternative minimum tax.
 
     Upon disposition of common shares acquired from exercise of an ISO,
long-term capital gain or loss is generally recognized in an amount equal to the
difference between the amount realized on the sale or disposition and the
exercise price. However, if the participant disposes of the common shares within
two years of the date of grant or within one year from the date of the issuing
of the common shares to the participant (a "Disqualifying Disposition"), then
the
 
                                       21
<PAGE>   23
 
participant will recognize ordinary income, as opposed to capital gain, at the
time of disposition in an amount generally equal to the lesser of (i) the amount
of gain realized on the disposition or (ii) the difference between the Fair
Market Value of the common shares received on the date of exercise and the
exercise price. Any remaining gain or loss is treated as a short-term or long-
term capital gain or loss, depending upon the period of time the common shares
have been held.
 
     The Company is not entitled to a tax deduction upon either exercise of an
ISO or disposition of common shares acquired pursuant to such exercise, except
to the extent that the participant recognizes ordinary income in a Disqualifying
Disposition.
 
     If the holder of an ISO pays the exercise price, in whole or in part, with
previously acquired shares, the exchange will not affect the tax treatment of
the exercise. Upon such exchange, and except for Disqualifying Dispositions, no
gain or loss is recognized upon the delivery of the previously acquired shares
to the Company, and the shares received by the participant equal in number to
the previously acquired shares exchanged therefor will have the same basis and
holding period for capital gain or capital loss purposes as the previously
acquired shares. Shares received by the participant in excess of the number of
previously acquired shares will have a basis of zero and a holding period which
commences as of the date the shares are issued to the participant upon exercise
of the ISO. If such an exercise is effected using shares previously acquired
through the exercise of an ISO, the exchange of the previously acquired shares
will be considered a disposition of such shares for the purpose of determining
whether a Disqualifying Disposition has occurred.
 
NQSOS
 
     In general, a participant receiving an NQSO generally does not recognize
taxable income on the date of grant of the NQSO. The participant must recognize
ordinary income generally at the time of exercise of the NQSO in the amount of
the difference between the Fair Market Value of the common shares on the date of
exercise and the option price. The ordinary income received will constitute
compensation for which tax withholding generally will be required. The amount of
ordinary income recognized by a participant will be deductible by the Company in
the year that the participant recognizes the income if the Company complies with
the applicable withholding requirement.
 
     Common shares acquired upon exercise of an NQSO will have a tax basis equal
to their fair market value on the exercise date or other relevant date on which
ordinary income is recognized, and the holding period for the common shares
generally will begin on the date of exercise or such other relevant date. Upon
subsequent disposition of the common shares, the participant will recognize
long-term capital gain or loss if the participant has held the common shares for
more than one year prior to disposition, or short-term capital gain or loss if
the participant has held the common shares for one year or less.
 
     If the holder of an NQSO pays the exercise price, in whole or in part, with
previously acquired shares, the exchange will not affect the tax treatment of
the exercise, i.e., the holder will recognize ordinary income in the amount by
which the fair market value of the shares received exceeds the exercise price.
Upon such exchange, no gain or loss is recognized upon delivery of the
previously acquired shares to the Company, and the shares received by the holder
equal in number to the previously acquired shares exchanged therefor will have
the same basis and holding period for capital gain purposes as the previously
acquired shares. Shares received by the holder of the NQSO in excess of the
number of previously acquired shares will have a basis equal to the fair market
value of such additional shares as of the date ordinary income equal to such
fair market value is realized and a holding period which commences as of such
date.
 
                                       22
<PAGE>   24
 
SARS AND STAND ALONE STOCK APPRECIATION RIGHTS
 
     A participant is not taxed upon the grant of SARS or Stand Alone Stock
Appreciation Rights. Rather, participants will generally be taxed upon the
exercise date, at ordinary income tax rates, on the amount of cash received and
the fair market value of any common shares received. The amount of ordinary
income recognized by a participant will be deductible by the Company in the year
in which the participant recognizes income.
 
RESTRICTED STOCK AWARDS
 
     An employee who is granted a restricted stock award will not be taxed upon
the acquisition of such common shares so long as the interest in such common
shares is subject to a substantial risk of forfeiture. Upon lapse or release of
the restrictions, the participant will be taxed at ordinary income tax rates on
an amount equal to either the current fair market value of the common shares (in
the case of lapse or termination) or the sale price (in the case of a sale),
less any consideration paid for the shares. The Company will be entitled to a
corresponding deduction. The basis of restricted shares held after lapse or
termination of restrictions will be equal to their fair market value on the date
of lapse or termination of restrictions, and upon subsequent disposition, any
further gain or loss will be long-term or short-term capital gain or loss,
depending upon the length of time the common shares are held.
 
     A participant may elect to be taxed at ordinary income tax rates on the
full fair market value of the restricted shares at the time of issuance (less
any consideration paid). The basis of the common shares so acquired will be
equal to the fair market value at such time. If the election is made, no tax
will be payable upon the subsequent lapse or release of the restrictions, and
any gain or loss upon disposition will be a capital gain or loss.
 
VOTE REQUIRED
 
     Shareholder approval of the Amendments to the 1993 Program will require the
affirmative vote of the holders of a majority of the Company's common shares
represented in person or by proxy at the Annual Meeting or any adjournment
thereof. Under Ohio Law, abstentions and broker non-votes are counted as
present; the effect of an abstention or broker non-vote on the proposal is the
same as a "no" vote.
 
     THE BOARD OF DIRECTORS OF THE COMPANY UNANIMOUSLY RECOMMENDS THAT THE
SHAREHOLDERS VOTE FOR THE PROPOSAL TO APPROVE THE AMENDMENTS TO THE 1993
PROGRAM. UNLESS OTHERWISE DIRECTED, THE PERSONS NAMED IN THE ENCLOSED PROXY WILL
VOTE THE COMMON SHARES REPRESENTED BY ALL PROXIES RECEIVED PRIOR TO THE ANNUAL
MEETING, AND NOT PROPERLY REVOKED, IN FAVOR OF THE AMENDMENTS TO THE 1993
PROGRAM.
 
                                 ANNUAL REPORT
 
     The Company's Annual Report for the fiscal year ended December 31, 1996
accompanies this Proxy Statement.
 
                         INDEPENDENT PUBLIC ACCOUNTANTS
 
     The accounting firm of Coopers & Lybrand has served for many years as
independent public accountants for the Company and its subsidiaries, and Coopers
& Lybrand will continue to serve as independent public accountants for 1997.
Management expects that representatives of that firm will be present at the
Annual Meeting, will have the opportunity to make a statement if they desire to
do so and will be available to respond to appropriate questions.
 
     The Company's financial statements for the last fiscal year were examined
by Coopers & Lybrand. In connection with the audit function, Coopers & Lybrand
also reviewed the Com-
 
                                       23
<PAGE>   25
 
pany's annual and quarterly reports and reviewed its filings with the Securities
and Exchange Commission.
 
                             SHAREHOLDER PROPOSALS
 
     If an eligible shareholder wishes to present a proposal for action at the
next annual meeting of shareholders of the Company, it must be received by the
Company not later than November 25, 1997 for inclusion in the Company's Proxy
Statement and form of Proxy relating to that meeting. An eligible shareholder
may present no more than one proposal of not more than five hundred (500) words,
including supporting statements, for inclusion in the Company's proxy materials
for the next annual meeting. Proposals shall be sent to Ohio Casualty
Corporation, Attention: Howard L. Sloneker III, Secretary, 136 North Third
Street, Hamilton, Ohio 45025.
 
          COMPLIANCE WITH SECTION 16(A) OF THE SECURITIES EXCHANGE ACT
 
     Section 16(a) of the Securities Exchange Act of 1934 requires the Company's
officers and directors, and persons who own more than ten percent of a
registered class of the Company's equity securities, to file reports of
ownership and changes in ownership on Forms 3, 4 and 5 with the Securities and
Exchange Commission (SEC). Officers, directors and greater than ten percent
shareholders are required by SEC regulations to furnish the Company with copies
of all Forms 3, 4 and 5 they file.
 
     Based on the Company's review of the copies of such forms it has received,
the Company believes that all its officers, directors, and greater than ten
percent beneficial owners complied with all filing requirements applicable to
them with respect to transactions during fiscal 1996.
 
                                 OTHER MATTERS
 
     The Company files annually with the Securities and Exchange Commission an
Annual Report on Form 10-K. This report includes financial statements and
financial statement schedules.
 
     A SHAREHOLDER OF THE COMPANY MAY OBTAIN A COPY OF THE ANNUAL REPORT ON FORM
10-K, INCLUDING FINANCIAL STATEMENTS AND FINANCIAL STATEMENT SCHEDULES, FOR THE
FISCAL YEAR ENDED DECEMBER 31, 1996, WITHOUT CHARGE BY SUBMITTING A WRITTEN
REQUEST THEREFOR TO THE FOLLOWING ADDRESS:
 
                        OHIO CASUALTY CORPORATION

     Management and the Board of Directors of the Company know of no business to
be brought before the Annual Meeting other than as set forth in this Proxy
Statement. However, if any matters other than those referred to in this Proxy
Statement should properly come before the Annual Meeting, it is the intention of
the persons named in the enclosed proxy to vote the common shares represented by
such proxy on such matters in accordance with their best judgment.

                            EXPENSES OF SOLICITATION
 
     The expense of proxy solicitation will be borne by the Company. Proxies
will be solicited by mail and may be solicited, for no additional compensation,
by officers, directors or employees of the Company or its subsidiaries, by
telephone, telegraph or in person. Brokerage houses and other custodians,
nominees and fiduciaries may be requested to forward soliciting material to the
beneficial owners of common shares of the Company, and will be reimbursed for
their related expenses. In addition, the Company has retained Morrow & Co.,
Inc., a professional soliciting organization, to assist in soliciting proxies
from brokerage houses, custodians and nominees. The fees and expenses of that
firm in connection with such solicitation are not expected to exceed $15,000.

             OHIO CASUALTY CORPORATION 1993 STOCK INCENTIVE PROGRAM
                     (AS AMENDED THROUGH FEBRUARY 20, 1997)
 
     1. PURPOSE.  The purpose of the Ohio Casualty Corporation 1993 Stock
Incentive Program (the "Program") is to attract and retain outstanding
individuals as directors, officers and other key employees of Ohio Casualty
Corporation (the "Company") and its Subsidiaries, and to furnish incentives to
such persons by providing such persons opportunities to acquire Common Shares of
the Company, or monetary payments based on the value of such shares, on
advantageous terms as herein provided.
 
     2. ADMINISTRATION.  The Program will be administered by a committee (the
"Committee") of at least three persons which shall be either the Executive
Compensation Committee of the Board of Directors of the Company or such other
committee comprised entirely of persons that are both (i) Non-Employee Directors
as defined in Rule 16b-3 promulgated by the Securities and Exchange Commission,
and (ii) "outside directors" as defined in Section 162(m) of the Internal
Revenue Code of 1986, as amended, and the regulations thereunder, as the Board
of Directors of the Company may from time to time designate. The Committee shall
interpret the Program, prescribe, amend and rescind rules and regulations
relating thereto, and make all other determinations necessary or advisable for
the administration of the Program. Any determination, decision or action of the
Committee in connection with the construction, interpretation, administration or
application of the Program shall be final, conclusive and binding upon all
persons participating in the Program and any person validly claiming under or
through persons participating in the Program. A majority of the members of the
Committee shall constitute a quorum at any meeting of the Committee, and all
determinations of the Committee at a meeting shall be made by a majority of its
members. Any determination of the Committee under the Program may be made
without a meeting of the Committee by a writing signed by all of its members.
The Company shall effect the granting of Awards under the Program in accordance
with the determination of the Committee, by execution of instruments in writing
in such form as approved by the Committee.
 
     With respect to persons subject to Section 16 of the Securities Exchange
Act of 1934, as amended (the "Exchange Act"), transactions under this Program
are intended to comply with all applicable conditions of Rule 16b-3 of the
Securities and Exchange Commission or its successors. To the extent any
provision of the Program or action by the Committee fails to so comply, it shall
be deemed null and void, to the extent permitted by law and deemed advisable by
the Committee.
 
     3. PARTICIPANTS.  Participants in the Program will consist of such officers
and other full-time, salaried employees of the Company and its Subsidiaries as
the Committee in its sole discretion may designate from time to time to receive
Awards hereunder. The Committee's designation of a Participant in any year shall
not require the Committee to designate such person to receive an Award in any
other year. The Committee shall consider such factors as it deems pertinent in
selecting Participants and in determining the type and amount of their
respective Awards, including without limitation (i) the financial condition of
the Company and its Subsidiaries; (ii) anticipated profits for the current or
future years; (iii) contributions of Participants to the profitability and
development of the Company and its Subsidiaries; and (iv) other compensation
provided to Participants. Non-Employee Directors shall also be Participants in
the Program solely for purposes of receiving Stock Options under Section 11
hereof. For purposes of Section 11 of the Program, the term "Non-Employee
Director" shall mean a member of the Board of Directors of the Company who is
not a full-time employee of the Company or any of its Subsidiaries.
 
                                       26

     4. TYPES OF AWARDS.  Awards under the Program may be granted in any one or
a combination of (a) Incentive Stock Options; (b) Non-Qualified Stock Options;
(c) Stock Appreciation Rights; (d) Limited Stock Appreciation Rights; (e) Stand
Alone Stock Appreciation Rights; and (f) Restricted Stock Awards, all as
described below in Sections 6-11 hereof. The maximum aggregate number of Common
Shares with respect to which Awards may be made to any Participant in any
calendar year is 75,000 Common Shares. For purposes of this limitation, a Stock
Option shall be treated as being made with respect to the number of Common
Shares that may be purchased with the Stock Option; a Stand Alone Stock
Appreciation Right shall be treated as being made with respect to the number of
Common Shares as to which the cash payment at exercise is computed; a Restricted
Stock Award shall be counted as being equal to the number of underlying Common
Shares; and Stock Appreciation Rights and Limited Stock Appreciation Rights
shall not enter into the computation hereunder if such Awards, when exercised,
will result in a related Stock Option being surrendered.
 
     5. SHARES RESERVED UNDER THE PROGRAM.  There is hereby reserved for
issuance under the Program an aggregate of One Million (1,000,000) Common
Shares, which may be newly issued or treasury shares. The Common Shares hereby
reserved are in addition to the Common Shares previously reserved under the
Company's 1982 Incentive Stock Program (the "Prior Stock Option Program"). Any
Common Shares reserved for issuance under the Prior Stock Option Program in
excess of the number of Common Shares as to which stock options or other awards
have been awarded thereunder on the Effective Date, plus any such shares as to
which stock options or other awards granted under the Prior Stock Option Program
may lapse, expire, terminate or be canceled after the Effective Date (so long as
the holder thereof has not received any benefits of ownership of such shares),
shall also be reserved and available for issuance in connection with Awards
under this Program. All of such shares may, but need not, be issued pursuant to
the exercise of Incentive Stock Options.
 
     If there is a lapse, expiration, termination or cancellation of any Award
granted hereunder without the issuance of Common Shares or payment of cash
thereunder, or if Common Shares are issued under any Award and thereafter are
reacquired by the Company pursuant to rights reserved upon the issuance thereof,
the Common Shares subject to or reserved for such Award may again be used for
new Stock Options or other Awards under this Program so long as the holder
thereof has not received any benefits of ownership of such shares; provided,
however, that in no event may the number of Commons Shares issued under this
Program exceed the total number of Common Shares reserved for issuance
hereunder.
 
     6. INCENTIVE STOCK OPTION PLAN.  Incentive Stock Options will consist of
Stock Options, qualifying as "incentive stock options" under the requirements of
Section 422 of the Code, to purchase Common Shares at purchase prices not less
than One Hundred Percent (100%) of the Fair Market Value of such Common Shares
on the date of grant. Incentive Stock Options will be exercisable over not more
than ten (10) years after the date of grant. In the event of termination of
employment for any reason other than Retirement, Disability or death, the right
of the optionee to exercise an Incentive Stock Option shall terminate
immediately upon the termination of employment. In the event of termination of
employment due to Retirement, the right of the optionee to exercise an Incentive
Stock Option shall terminate upon the earlier of the end of the original term of
the Incentive Stock Option or three (3) months after the date of such
Retirement. In the event of termination of employment due to Disability, the
right of the optionee to exercise an Incentive Stock Option shall terminate upon
the earlier of the end of the original term of the Incentive Stock Option or one
(1) year after the date of termination of employment. If the optionee should die
while employed, the right of the optionee's successor in interest to exercise an
Incentive Stock Option granted to the optionee shall terminate upon the earlier
of the end of the original term of the Incentive Stock Option or one (1) year
after optionee's last date of employment. If the optionee should die within
three (3) months after termination of employment due to Retirement, the right of
his or her successor in interest to
 
                                       27
<PAGE>   29
 
exercise an Incentive Stock Option shall terminate three (3) months after the
date of termination of employment as a result of such Retirement, but not later
than the end of the original term of the Incentive Stock Option. If the optionee
should die within one (1) year after termination of employment due to
Disability, the right of his or her successor in interest to exercise an
Incentive Stock Option shall terminate upon the earlier of one (1) year after
the date of termination of employment or the end of the original term of the
Incentive Stock Option. The aggregate fair market value (determined as of the
time the Stock Option is granted) of the Common Shares with respect to which
incentive stock options are exercisable for the first time by any Participant
during any calendar year (under all option plans of the Company and all
Subsidiaries and Parents of the Company) shall not exceed $100,000. An Incentive
Stock Option granted to a Participant under the Program may be exercised only
after six (6) months from its grant date. Anything contained herein to the
contrary notwithstanding, no Incentive Stock Option shall be granted to an
employee who, at the time the Incentive Stock Option is granted, owns (actually
or constructively under the provisions of Section 424(d) of the Code) stock
possessing more than 10% of the total combined voting power of all classes of
stock of the Company or of any Parent or Subsidiary of the Company, unless the
option exercise price is not less than 110% of the Fair Market Value of the
Common Shares subject to the Incentive Stock Option on the date of grant and the
Incentive Stock Option by its terms is not exercisable more than five years from
the date it is granted. For purposes of this Section 6, if an optionee
terminates his employment voluntarily, the date of termination of employment
shall be deemed the date on which he notifies the Company of his intention to
terminate his employment; in all other cases the date of termination of
employment shall be the last day of employment.
 
     7. NON-QUALIFIED STOCK OPTION PLAN.  Non-Qualified Stock Options will
consist of options (other than Incentive Stock Options) to purchase Common
Shares at purchase prices not less than One Hundred Percent (100%) of the Fair
Market Value of such Common Shares on the date of grant. Non-Qualified Stock
Options will be exercisable over not more than ten (10) years after the date of
grant. In the event of termination of employment for any reason other than
Retirement, Disability or Death, the right of the optionee to exercise a
Non-Qualified Stock Option shall terminate immediately upon the termination of
employment. In the event of termination of employment due to Retirement or
Disability, or if the optionee should die while employed, the right of the
optionee or his or her successor in interest to exercise a Non-Qualified Stock
Option shall terminate upon the earlier of the end of the original term of the
Non-Qualified Stock Option or one (1) year after the date of termination of
employment as a result of such Retirement, Disability or Death. If the optionee
should die within one (1) year after termination of employment due to Retirement
or Disability, the right of his or her successor in interest to exercise a
Non-Qualified Stock Option shall terminate upon the earlier of one (1) year
after termination of employment as a result of such Retirement or Disability or
the end of the original term of the Non-Qualified Stock Option. A Non-Qualified
Stock Option granted to a Participant under the Program may be exercised only
after six (6) months from its grant date. For purposes of this Section 7, if an
optionee terminates his employment voluntarily, the date of termination of
employment shall be deemed the date on which he notifies the Company of his
intention to terminate his employment; in all other cases the date of
termination shall be the last day of employment.
 
     8. STOCK APPRECIATION RIGHTS PLAN.  The Committee may, in its discretion,
grant a Stock Appreciation Right to the holder of any Stock Option granted
hereunder. Such Stock Appreciation Rights shall be subject to such terms and
conditions consistent with the Program as the Committee shall impose from time
to time, including the following:
 
          (a) A Stock Appreciation Right may be granted with respect to a Stock
     Option at the time of its grant or at any time thereafter up to six (6)
     months prior to its expiration.
 
                                       28
<PAGE>   30
 
          (b) Stock Appreciation Rights will permit the holder to surrender any
     related Stock Option or portion thereof which is then exercisable and to
     elect to receive in exchange therefor cash in an amount equal to:
 
             (i) The excess of the Fair Market Value on the date of such
        election of one Common Share over the option exercise price, multiplied
        by
 
             (ii) The number of Common Shares covered by such Stock Option or
        portion thereof which is so surrendered.
 
          (c) A Stock Appreciation Right granted to a Participant under the
     Program may be exercised only after six (6) months from its grant date.
 
          (d) The Committee shall have the discretion to satisfy a Participant's
     right to receive the amount of cash determined under subsection (b) hereof,
     in whole or in part, by the delivery of Common Shares valued as of the date
     of the Participant's election.
 
          (e) A Stock Appreciation Right may be granted to a Participant
     regardless of whether such Participant has been granted a Limited Stock
     Appreciation Right with respect to the same Stock Option. However, a Stock
     Appreciation Right may not be exercised during any period that a Limited
     Stock Appreciation Right with respect to the same Stock Option may be
     exercised.
 
          (f) In the event of the exercise of a Stock Appreciation Right, the
     number of Common Shares reserved for issuance hereunder shall be reduced by
     the number of shares covered by the Stock Option or portion thereof
     surrendered.
 
     8A. STAND ALONE STOCK APPRECIATION RIGHTS PLAN.  The Committee may, in its
discretion, grant Stand Alone Stock Appreciation Rights to any Participant. Such
Stand Alone Stock Appreciation Rights shall be subject to such terms and
conditions consistent with the Program as the Committee shall impose from time
to time, including the following:
 
          (a) Stand Alone Stock Appreciation Rights shall be granted without
     reference to any Stock Option which is then exercisable.
 
          (b) Each Stand Alone Stock Appreciation Right will permit the holder
     to elect to receive in exchange therefor cash in an amount equal to the
     excess of:
 
             (i) the Fair Market Value on the date of such election of one
        Common Share, over
 
             (ii) the Fair Market Value of one Common Share on the date which
        the Stand Alone Stock Appreciation Right was granted.
 
          (c) A Stand Alone Stock Appreciation Right granted to a Participant
        under the Program may be exercised only after six (6) months from its
        grant date.
 
          (d) The Committee shall have the discretion to satisfy a Participant's
     right to receive the amount of cash determined under subsection (b) hereof,
     in whole or in part, by the delivery of Common Shares valued as of the date
     of the Participant's election.
 
          (e) Stand Alone Stock Appreciation Rights will be exercisable over not
     more than ten (10) after the date of grant.
 
          (f) In the event of termination of employment of a Participant to whom
     a Stand Alone Stock Appreciation Right is granted for any reason other than
     Retirement, Disability or death, the right of the holder to exercise such
     Stand Alone Stock Appreciation Right shall terminate immediately upon the
     termination of employment. In the event of termination of employment due to
     Retirement or Disability, or if the optionee should die while employed, the
     right of the holder or his or her successor in interest to exercise a Stand
     Alone Stock Appreciation Right shall terminate upon the earlier of the end
     of the original term of the
 
                                       29
<PAGE>   31
 
     Stand Alone Stock Appreciation Right or one (1) year after the date of
     termination of employment as a result of such Retirement, Disability or
     Death. If the holder should die within one (1) year after termination of
     employment due to Retirement or Disability, the right of his or her
     successor in interest to exercise a Stand Alone Stock Appreciation Right
     shall terminate upon the earlier of one (1) year after termination of
     employment as a result of such Retirement or Disability or the end of the
     original term of the Stand Alone Stock Appreciation Right. For purposes of
     this Section 8A, if a holder terminates his employment voluntarily, the
     date of termination of employment shall be deemed the date on which he
     notifies the Company of his intention to terminate his employment; in all
     other cases the date of termination of employment shall be the last day of
     employment.
 
          (g) In the event of the grant of any Stand Alone Stock Appreciation
     Rights, the number of Common Shares reserved for issuance hereunder shall
     be reduced by the number of Stand Alone Stock Appreciation Rights granted.
 
     9. LIMITED STOCK APPRECIATION RIGHTS PLAN.  The Committee may, in its
discretion, grant a Limited Stock Appreciation Right to the holder of any Stock
Option granted hereunder. Such Limited Stock Appreciation Rights shall be
subject to such terms and conditions consistent with the Program as the
Committee shall impose from time to time, including the following:
 
          (a) A Limited Stock Appreciation Right may be granted with respect to
     a Stock Option at the time of its grant or at any time thereafter up to six
     (6) months prior to its expiration.
 
          (b) A Limited Stock Appreciation Right will permit the holder to
     surrender any related Stock Option or portion thereof which is then
     exercisable and to receive in exchange therefor cash in an amount equal to:
 
             (i) The excess of the Fair Market Value on the date of such
        election of one Common Share over the option exercise price, multiplied
        by
 
             (ii) The number of Common Shares covered by such Stock Option or
        portion thereof which is so surrendered.
 
          (c) A Limited Stock Appreciation Right granted to a Participant under
     the Program may be exercised only after six (6) months from its grant date
     and only during the sixty (60) day period commencing with the day following
     the date of a Change in Control.
 
          (d) A Limited Stock Appreciation Right may be granted to a Participant
     regardless of whether such Participant has been granted a Stock
     Appreciation Right with respect to the same Stock Option.
 
          (e) In the event of the exercise of a Limited Stock Appreciation
     Right, the number of Common Shares reserved for issuance hereunder shall be
     reduced by the number of Common Shares covered by the Stock Option or
     portion thereof surrendered.
 
     10. RESTRICTED STOCK AWARDS PLAN.  Restricted Stock Awards will consist of
Common Shares transferred to Participants without other payment therefor (other
than the payment of the par value of such shares if required by applicable law)
as additional compensation for their services to the Company or one of its
Subsidiaries. Restricted Stock Awards shall be subject to such terms and
conditions as the Committee determines appropriate including, without
limitation, restrictions on the sale or other disposition of such shares and
rights of the Company to reacquire such shares upon termination of the
Participant's employment within specified periods. Subject to such other
restrictions as are imposed by the Committee, the Common Shares covered by a
Restricted Stock Award granted to a Participant under the Program may be sold or
otherwise disposed of only after six (6) months from the grant date of the
award.

     11. NON-QUALIFIED STOCK OPTION AWARDS FOR NON-EMPLOYEE DIRECTORS.
 
          (a) Grant of Options.  Each person who is a Non-Employee Director
     shall be granted a Non-Qualified Stock Option to purchase 3,000 Common
     Shares effective on the third business day following the date of his or her
     first election or appointment to the Board of Directors and on the third
     business day following each annual meeting of shareholders at which he or
     she is re-elected to the Board of Directors.
 
          (b) Price.  The option exercise price per share of each Non-Qualified
     Stock Option granted under this Section 11 shall be equal to the Fair
     Market Value of a Common Share on the date of grant, provided that the
     option exercise price shall be subject to adjustment as provided in Section
     18 hereof:
 
          (c) Term of Options.  Non-Qualified Stock Options granted under this
     Section 11 shall be effective on and shall be of a term of ten (10) years
     from the date of grant. Each such option shall be subject to earlier
     termination as provided in subsection (e) hereof.
 
          (d) Restriction on Exercise.  Non-Qualified Stock Options granted
     under this Section 11 may not be exercised within six (6) months following
     their date of grant.
 
          (e) Termination of Service as a Director.
 
             (i) Except as otherwise provided in this subsection (e), any
        Non-Qualified Stock Option granted under this Section 11 is exercisable
        only by the optionee, is exercisable only while the optionee is a
        director of the Company and then only if the option has become
        exercisable by its terms, and if not exercisable by its terms at the
        time the optionee ceases to be a director of the Company, shall
        immediately expire on the date the optionee ceased to be a director of
        the Company.
 
             (ii) Any Non-Qualified Stock Option granted under this Section 11
        which is exercisable by its terms at the time the optionee ceases to be
        a director of the Company must be exercised on or before the earlier of
        three months after the date the optionee ceases to be a director of the
        Company or the expiration date of such option, after which period such
        option shall expire. Notwithstanding the foregoing, if an optionee's
        status as a director of the Company is Terminated For Cause (as herein
        defined), however, all options granted to such optionee shall, to the
        extent not previously exercised, expire immediately upon such
        termination.
 
             (iii) In the event of the death of the holder of a Non-Qualified
        Stock Option granted under this Section 11 while a director of the
        Company or within three months after he ceases to be a director of the
        Company, such optionee's unexercised Non-Qualified Stock Option (whether
        or not then exercisable by its terms) shall become immediately
        exercisable by the optionee's successor in interest for a period ending
        on the earlier of the end of the original term of the option or twelve
        months after the date of death, after which period such option shall
        expire.
 
             (iv) In the case of any Non-Qualified Stock Option granted under
        this Section 11, in the event the optionee ceases to be a director of
        the Company by reason of a Disability, such optionee's unexercised
        Non-Qualified Stock Option (whether or not then exercisable by its
        terms) shall become immediately exercisable for a period ending on the
        earlier of the end of the original term of such option or twelve months
        from the date the optionee ceases to be a director, after which period
        such option shall expire.
 
          (f) Except in the event of conflict, all provisions of the Program
     shall apply to this Section 11. In the event of any conflict between the
     other provisions of the Program and this Section 11, this Section 11 shall
     control. Those provisions of Sections 8 and 9 hereof which authorize the
     Committee to grant a Stock Appreciation Right or a Limited Stock
     Appreciation Right with respect to a Stock Option shall not apply to any
     Non-Qualified Stock Option
 
                                       31
<PAGE>   33
 
     granted under this Section 11. Those provisions of Section 14 hereof which
     authorize the Committee to declare outstanding options to be vested and to
     amend or modify the terms of any Awards shall not apply to any
     Non-Qualified Stock Option granted under this Section 11.
 
     12. NONTRANSFERABILITY.  Each Stock Option, Stock Appreciation Right, Stand
Alone Stock Appreciation Right, Limited Stock Appreciation Right and Restricted
Stock Award granted under this Program shall not be transferable other than by
will or the laws of descent and distribution, and shall be exercisable, during
the Participant's lifetime, only by the Participant or the Participant's
guardian or legal representative.
 
     13. OTHER PROVISIONS.  The grant of any Award under the Program may also be
subject to other provisions (whether or not applicable to any Award granted to
any other Participant) as the Committee determines appropriate including,
without limitation, provisions for the purchase of Common Shares under Stock
Options in installments, provisions for the payment of the option exercise price
of shares under a Stock Option by delivery of other Common Shares of the Company
having a then Fair Market Value equal to the option exercise price of such
shares, restrictions on resale or other disposition, such provisions as may be
appropriate to comply with federal or state securities laws and stock exchange
requirements and understandings or conditions as to the Participant's employment
in addition to those specifically provided for under the Program.
 
     The Committee may, in its discretion, permit payment of the option exercise
price of shares under Stock Options by delivery of a properly executed exercise
notice together with a copy of irrevocable instructions to a broker to deliver
promptly to the Company the amount of sale or loan proceeds to pay the option
exercise price. To facilitate the foregoing, the Company may enter into
agreements for coordinated procedures with one or more brokerage firms.
 
     The Committee may, in its discretion and subject to such rules as it may
adopt, permit a Participant (other than a Non-Employee Director who receives a
Non-Qualified Stock Option under Section 11 hereof) to pay all or a portion of
the federal, state and local taxes, including FICA withholding tax, arising in
connection with the following transactions: (a) the exercise of a Non-Qualified
Stock Option; (b) the lapse of restrictions on Common Shares received as a
Restricted Stock Award; or (c) the receipt or exercise of any other Award; by
electing (i) to have the Company withhold Common Shares, (ii) to tender back
Common Shares received in connection with such Award or (iii) to deliver other
previously acquired Common Shares of the Company having a Fair Market Value
approximately equal to the amount to be withheld.
 
     14. TERM OF PROGRAM AND AMENDMENT, MODIFICATION, CANCELLATION OR
ACCELERATION OF AWARDS.  No Award shall be granted under the Program more than
ten (10) years after the date of the original adoption of this Program by the
Company's Board of Directors. The terms and conditions applicable to any Award
granted prior to such date may at any time be amended, modified or canceled,
without shareholder approval, by mutual agreement between the Committee and the
Participant or such other persons as may then have an interest therein, so long
as shareholder approval of such amendment, modification or cancellation is not
required under Rule 16b-3 of the Securities and Exchange Commission or any
applicable requirements of any securities exchange on which are listed any of
the Company's equity securities or any applicable requirements for issuers whose
securities are traded in the NASDAQ National Market System or any applicable
requirements of the Code. The Committee may, at any time and in its sole
discretion, declare any or all Stock Options, Stock Appreciation Rights and
Stand Alone Stock Appreciation Rights then outstanding under this Program or the
Prior Stock Option Program to be exercisable and any or all then outstanding
Restricted Stock Awards to be vested, whether or not such options, rights or
awards are then otherwise exercisable or vested.
 
     15. AMENDMENT TO PRIOR STOCK OPTION PROGRAM.  No Stock Options or other
awards shall be granted under the Prior Stock Option Program on or after the

          (b) In the event of any change in capitalization affecting the Common
     Shares, such as a stock dividend, stock split, recapitalization, merger,
     consolidation, split-up, combination or exchange of shares or other form of

<PAGE>   37
 
             (iii) All terms and conditions of all Restricted Stock Awards then

        Control, whether or not then otherwise satisfied.
 
     19. AMENDMENT AND TERMINATION OF PROGRAM.  The Board of Directors of the

time without the approval of the shareholders of the Company except as such
shareholder approval may be required (a) to satisfy the requirements of Rule
16b-3 of the Securities and Exchange Commission, (b) to satisfy applicable
requirements of the Code or (c) to satisfy applicable requirements of any
securities exchange on which are listed any of the Company's equity securities
or any requirements applicable to issuers whose securities are traded in the
NASDAQ National Market System. No such action to amend or terminate the Program
shall reduce the then existing amount of any Participant's Award or adversely
change the terms and conditions thereof without the Participant's consent.
Section 11 of the Program may not be amended more frequently than once every six
months other than to comport with changes in the Code, or changes in the
Employees Retirement Income Securities Act, or the rules thereunder, and no
amendment of the Program shall result in any Committee member losing his or her
status as a "disinterested person" as defined in Rule 16b-3 of the Securities
and Exchange Commission with respect to any employee benefit plan of the Company
or result in the Program losing its status as a plan satisfying the requirements
of said Rule 16b-3.
 
     20. NO RIGHT TO EMPLOYMENT.  Neither the adoption of the Program nor the
granting of any Awards hereunder shall confer upon any employee of the Company
or any Subsidiary any right to continued employment with the Company or any
Subsidiary, as the case may be, nor shall it interfere in any way with the right
of the Company or a Subsidiary to terminate the employment of any of its
employees at any time, with or without cause.
 
     21. UNFUNDED PLAN.  The Program shall be unfunded and the Company shall not
be required to segregate any assets that may at any time be represented by
Awards under the Program. Any liability of the Company to any person with
respect to any Awards under the Program shall be based solely upon any
contractual obligations that may be effected pursuant to the Program. No such
obligation of the Company shall be deemed to be secured by any pledge of, or
other encumbrance on, any property of the Company or any Subsidiary.
 
     22. PAYMENTS TO TRUST.  The Committee is authorized to cause to be
established a trust agreement or several trust agreements whereunder the
Committee may make payments of amounts due or to become due to Participants in
the Program.
 
     23. ENGAGING IN COMPETITION WITH COMPANY.  In the event a Participant
terminates his or her employment with the Company or a Subsidiary for any reason
whatsoever, and within eighteen (18) months after the date thereof accepts
employment with any competitor of, or otherwise engaged in competition with, the
Company or any subsidiary, the Committee, in its sole discretion, may require
such Participant to return to the Company the economic value of any Award which
is realized or obtained (measured at the date of exercise, vesting or payment)
by such Participant at any time during the period beginning on that date which
is six months prior to the date of such Participant's termination of employment
with the Company or any Subsidiary.
 
     24. OTHER COMPANY AWARD AND COMPENSATION PROGRAMS.  Payments and other
Awards received by a Participant under the Program shall not be deemed a part of
a Participant's regular, recurring compensation for purposes of any termination
indemnity or severance pay law and shall not be included in, nor have any effect
on, the determination of Awards under any other employee benefit plan or similar
arrangement provided by the Company or a Subsidiary unless expressly so provided
by such other plan or arrangements, or except where the Committee or the Board
of Directors determines that an Award or portion of an Award should be included
to accurately reflect competitive compensation practices or to recognize that an
 
                                       36
<PAGE>   38
 
Award has been made in lieu of a portion of competitive annual cash
compensation. Awards under the Program may be made in combination with or in
tandem with, or as alternatives to, grants, awards or payments under any other
Company or Subsidiary plans. The Program notwithstanding, the Company or any
Subsidiary may adopt such other compensation programs and additional
compensation arrangements as it deems necessary to attract, retain and reward
employees for their service with the Company and its Subsidiaries.
 
     25. SECURITIES LAW RESTRICTIONS.  No Common Shares shall be issued under
the Program unless counsel for the Company shall be satisfied that such issuance
will be in compliance with applicable federal and state securities law.
Certificates for Common Shares delivered under the Program may be subject to
such stock-transfer orders and other restrictions as the Committee may deem
advisable under the rules, regulations and other requirements of the Securities
and Exchange Commission, any stock exchange upon which the Common Shares are
then listed or traded on the NASDAQ National Market System or any applicable
federal or state securities law. The Committee may cause a legend or legends to
be put on any such certificates to make appropriate reference to such
restrictions.
 
     26. AWARD AGREEMENT.  Each Participant receiving an Award under the Program
shall enter into an agreement with the Company in a form specified by the
Committee agreeing to the terms and conditions of the Award and such related
matters as the Committee shall, in its sole discretion determine.
 
     27. COST OF PROGRAM.  The costs and expenses of administering the Program
shall be borne by the Company.
 
     28. GOVERNING LAW.  The Program and all actions taken thereunder shall be
governed by and construed in accordance with the laws of the State of Ohio.
 
     29. SHAREHOLDER APPROVAL.  The Program was adopted by the Board of
Directors of the Company on February 18, 1993. The Program and any Award granted
thereunder shall be null and void if shareholder approval is not obtained within
twelve (12) months of the adoption of the Program by the Board of Directors.
