PART I

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 five
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; American Fire
and Casualty Company ("American Fire"), an Ohio corporation (originally
incorporated under the laws of the State of Florida) acquired in 1969; Avomark
Insurance Company ("Avomark"), an Indiana corporation created in 1997 and Ohio
Casualty of New Jersey, Inc. ("OCNJ"), an Ohio corporation created in 1998. 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.

On December 1, 1998, the Corporation acquired substantially all of the
Commercial Lines Division of Great American Insurance Company ("GAI"), an
insurance subsidiary of the American Financial Group, Inc. As part of the
transaction, the Corporation assumed responsibility for 650 employees of GAI's
Commercial Lines Division, as well as relationships with 1,700 agents. The major
lines of business included in the sale were workers' compensation, commercial
multi-peril, umbrella and commercial auto. Four commercial operations as well as
all California business and all pre-1987 environmental claims were excluded from
the transaction.

Under the asset purchase agreement, the Corporation assumed $645.8 million of
commercial lines insurance liabilities, $62.6 million in other liabilities and
acquired $287.9 million of investments, $1.5 million in cash and $119.1 million
in other assets. This resulted in an assumption by the Corporation of a net
statutory-basis liability of $300.0 million plus warrants to purchase 3 million
shares of Ohio Casualty Corporation common stock at a price of $45.01. In
addition, if the annualized production from the transferred agents at the end of
eighteen months equals or exceeds the production in the twelve months prior to
closing, GAI will receive an additional $40.0 million. This bonus payment grades
down ratably where if eighteen-month annualized production equals 71% or less of
previous production, no bonus payment is required. The bonus payment will be
accrued as additional goodwill when minimum contingency is achieved. Additional
information related to the accounting treatment of the acquisition as well as
proforma results are set forth in Note 14, Acquisition of Commercial Lines
Business, in the Notes to the Consolidated Financial Statements in Item 14 on
pages 57 and 58 of this Form 10-K.

ITEM 1. CONTINUED


During 1995, the Corporation's life insurance 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. 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. During the fourth quarter of 1997, Great
Southern Life Insurance Company legally replaced Ohio Life as the primary
insurer for approximately 76% of the life insurance policies subject to the 1995
agreement. As a result of this assumption, fourth quarter net income was
positively impacted by a partial recognition of unamortized ceding commission.
The after-tax impact was an increase to net income of $5.3 million. At December
31, 1998, Great Southern had assumed 95% of the life insurance policies subject
to the 1995 agreement. As a result, the Corporation recognized an additional
amount of unamortized ceding commission of $1.1 million before tax during the
fourth quarter 1998. There remains approximately $1.1 million in unamortized
ceding commission. This will continue to be amortized over the remaining life of
the underlying policies. Net income from discontinued operations amounted to
$1.9 million or $.06 per share in 1998 compared with $8.7 million or $.25 per
share in 1997 and $5.3 million or $.15 per share in 1996. Additional information
related to the discontinued life insurance operations is included in Item 14,
Note 20 Discontinued Operations on page 60 of this Form 10-K.

(B) FINANCIAL INFORMATION ABOUT INDUSTRY SEGMENTS

The revenues, operating profit and combined ratios of each industry segment for
the three years ended December 31, 1998 are set forth in Item 14, Note 13,
Segment Information, in the Notes to the Consolidated Financial Statements on
pages 56 and 57 of this Form 10-K.

Property and casualty net premiums written increased 7.6% in 1998. This increase
includes $31.6 million in net premium written from the acquisition of the
Commercial Lines business of GAI. Excluding GAI effects, net premiums written
increased 5.5%. This increase is primarily due to the Corporation's successful
year in personal auto, homeowners and CMP.

Excluding the effects of the GAI acquisition, New Jersey net premiums written
decreased 1.4%, primarily due to a decline in the workers' compensation, general
liability and commercial auto lines of business. Ohio and Kentucky net premiums
written increased 12.8% and 18.8%, respectively. These results are largely due
to the successful growth in our auto and homeowners lines of business.

(C) NARRATIVE DESCRIPTION OF BUSINESS

The Ohio Casualty Group is represented on a commission basis by approximately
5,433 independent insurance agents. In most cases, these agents also represent
other unaffiliated companies which may compete with the Ohio Casualty Group. The
34 claim and 12 underwriting and service offices operated by the Ohio Casualty
Group assist these independent agents in producing and servicing the Group's
business.

The following table shows consolidated direct premiums written for the Ohio
Casualty Group's ten largest states:

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.

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 63 corporate borrowers in
approximately 42 industries. At December 31, 1998, the market value of the
Corporation's five largest investments in below investment grade securities
totaled $35.5 million, and had an approximate amortized cost of $36.1 million.
None of these holdings individually exceeded $10.3 million.

At December 31, 1998, the fixed income portfolio relating to property and
casualty operations totaled $2.4 billion which consisted of 91.1% investment
grade securities and 8.9% below investment grade and/or unrated securities. At
December 31, 1998, the fixed income portfolio relating to discontinued
operations totaled $9.4 million, all of which are classified as investment grade
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
8.9% and 8.6% at December 31, 1998 and 1997, respectively. Below investment
grade securities were yielding 8.8% and 9.3% at December 31, 1998 and 1997,
respectively, while investment grade securities were yielding 8.9% in 1998 and
8.5% in 1997. Yield for tax exempt securities was 6.0% and 6.2% at December 31,
1998 and 1997, respectively, 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, 1998, the portfolio consisted of 58 separate issues, diversified
across 42 different industries; and the largest single position was 13.2% 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.

ITEM 1. CONTINUED

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
Item 14, Note 2, Investments, in the Notes to Consolidated Financial Statements
on pages 49 and 50 of this Form 10-K.

Purchases of taxable fixed income securities in 1998 were as follows: $172.5
million of investment grade securities, $119.1 million of high yield securities
and $54.4 million of unrated securities. Purchases of tax-exempt and equity
securities in 1998 totaled $121.3 million and $32.5 million, respectively.

Disposals (including maturities, calls, exchanges and scheduled prepayments) of
taxable fixed income securities in 1998 were as follows: $274.9 million of
investment grade securities, $58.7 million of high yield securities and $94.0
million of unrated securities. Dispositions of tax-exempt and equity securities
in 1998 totaled $133.8 million and $73.1 million, respectively.

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 Item 14, Note 17 on pages 58
and 59 of this Form 10-K, we have an interest rate swap with Chase Manhattan
Bank covering $15.0 million of the outstanding balance of the revolving line of
credit. This swap is not classified as an investment but rather as a hedge
against a portion of the variable rate loan.

Consolidated net realized investment gains (before taxes) in 1998 totaled $14.4
million, $.44 per share. Included in this amount are approximately $8.1 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. In November 1997, the Board of Directors authorized an additional
1,500,000 shares to be repurchased and again in 1998 an additional authorization
of 1,400,000 shares. During 1998, 2,362,900 shares were repurchased for $100
million. This compares with 1,544,688 shares repurchased in 1997 for $64.9
million and 264,600 shares repurchased in 1996 for $9.2 million. This brings the
remaining repurchase authorization to 1,063,912 shares as of December 31, 1998.

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

ITEM 1. CONTINUED

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 1997,
1996 and 1995 were reduced in the subsequent year as shown below:

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. In 1998, 1997 and 1996 there were 37, 25 and 41
catastrophes, respectively. The largest catastrophe in each year was $7.3
million, $4.6 million and $13.7 million in incurred losses. Additional
catastrophes with over $1.0 million in incurred losses number 14, 3 and 10 in
1998, 1997 and 1996, respectively. For additional discussion of catastrophe
losses, refer to Item 14, Note 9, Losses and Loss Reserves in the Notes to the
Consolidated Financial Statements on pages 54 and 55 of this Form 10-K.

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 tables present 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
Item 14, Notes 1H, Accounting Policies and 9, Losses and Loss Reserves, in the
Notes to Consolidated Financial Statements on pages 48 and 54 and 55 of this
Form 10-K.

ITEM 1. CONTINUED

REINSURANCE

In order to preserve capital and shareholder value, Ohio Casualty Corporation
purchases reinsurance to protect the Corporation against large or catastrophic
losses. As a result of the Corporation's acquisition of the majority of the
commercial lines division of Great American Insurance Company, the Corporation's
reinsurance program was expanded to address the additional concentrations of
underwriting exposures. 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. Property reinsurance covers $29.0 million in excess of
the retention. The Casualty Per Occurrence contract covers the Corporation in
the event an insured sustains a liability loss in excess of $1.0 million in a
single insured event. Workers' compensation, umbrella and other casualty
reinsurance covers $100.0 million, $50.0 million and $24.0 million,
respectively, in excess of the retention. The Corporation also carries various
facultative reinsurance contracts protecting against certain individual risks.

The Catastrophe reinsurance contract protects the Corporation against an
accumulation of losses arising from one defined catastrophic occurrence or
series of events. The 1999 catastrophe program, similar to 1998, provides $150.0
million coverage in excess of the Corporation's $25.0 million retention. In
1998, a portion of the catastrophe program was again renewed with a multi-year
placement. The multi-year placements maintain rates, continuity and each
reinsurers' overall share of the program. Over the last twenty years, there were
two events that triggered coverage under our catastrophe reinsurance contract.
Losses and loss adjustment expenses from the Oakland Fires in 1991 and Hurricane
Andrew in 1992 totaled $35.6 million and $29.8 million, respectively. Both of
these losses exceeded our prior retention amount of $13.0 million. The
Corporation recovered $33.9 million from reinsurers as a result of these events.
Our reinsurance limits are designed to cover exposure to a catastrophic event
expected to occur once every 300 years.

Reinsurance contracts do not relieve the Corporation of its obligation to the
policyholders. The collectibility of reinsurance is subject to the solvency of
the reinsurers. Since the Corporation's reinsurance protection is an important
component in our financial plan, we closely monitor the financial health and
claims settlement performance of each of our reinsurers. Annually, financial
statements are reviewed and various ratios calculated to identify reinsurers who
have ceased to meet our high standards of financial strength. If any reinsurers
fail these tests, they are removed from the program at renewal. Currently, all
domestic reinsurers have an AM Best rating of A or better, and the financial
condition of all international reinsurers meet the Corporation's high standards.
Additionally, the Corporation utilizes a large base of reinsurers to mitigate
its concentration risk. In 1998 and 1997, no reinsurer accounted for more than
10% of total ceded premiums. In 1996, only three reinsurers exceeded 10% of
total ceded premiums: Everest Reinsurance Company, MidOcean Reinsurance Company
and Kemper Reinsurance Company accounted for 16.79%, 10.65% and 10.52% of total
ceded premiums, respectively. As a result of the Corporation's controls over
reinsurance, uncollectible amounts have not been significant.

COMPETITION

More than 2,400 property and casualty insurance companies compete in the United
States and no one company or company group has a market share greater than
approximately 12.6%. The Ohio Casualty Group ranked as the forty-fourth largest
property and casualty insurance groups in the United States based on net
insurance premiums written in 1997, the latest year for which statistics are
available. The Ohio Casualty Group competes with other companies on the basis of
service, price and coverage.

ITEM 1. CONTINUED

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, Ohio Security and OCNJ are all domiciled
in Ohio. West American and Avomark are domiciled in Indiana. Collectively, the
Ohio Casualty Group is authorized to transact the business of insurance in the
District of Columbia and all states. 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. As construed by the California Supreme
Court, the proposition requires premium rate rollbacks for 1989 California
policyholders while allowing for a "fair" return for insurance companies. 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 assessed the Corporation $59.9
million for Proposition 103. 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 actual commissions and premium taxes paid. The assessment
was revised again in August 1995 to $42.1 million plus interest. In December
1997, during Administrative Law hearings, the California Department of Insurance
filed two revised rollback calculations. These calculations indicated rollback
liabilities of either $35.9 million or $39.9 million plus interest.

In 1998, the Administrative Law Judge finally issued a proposed ruling with a
rollback liability of $24.4 million plus interest. Her ruling was sent to the
California Commissioner of Insurance to be accepted, rejected or modified. The
Corporation expected the commissioner to rule sometime after the election in
November, but he has so far failed to do so. In light of this failure to rule,
the Corporation consulted extensively with outside counsel to determine the
range of liability asserted by the Department. The asserted rollbacks to date
have ranged from $24.4 million to $61.2 million. The Administrative Law Judge
indicates clearly in her ruling that by her calculation the Corporation would
have lost approximately $1.0 million on 1989 operations if a rollback of $24.4
million were imposed. Given that conclusion, it is clear that any assessment
greater than $24.4 million would strengthen the Corporation's Constitutional
argument that this rollback is confiscatory. Since the Corporation does not
believe it is possible to pinpoint a specific rollback within the California
Department of Insurance's asserted range that is the most probable, the
Corporation has established a contingent liability for Proposition 103 rollback
at $24.4 million plus simple interest at 10% from May 8, 1989. This brings the
total reserve to $48.0 million at December 31, 1998.


15


16



ITEM 1. CONTINUED

The Corporation will continue to challenge the validity of any rollback. To
date, the Corporation has paid $4.8 million in legal costs related to the
withdrawal, Proposition 103, and Fair Plan assessments.

In December 1992, the Corporation stopped writing business in California due to
a lack of profitability and a difficult regulatory environment. In April 1995,
the California Department of Insurance gave final approval for withdrawal.
Currently, subsidiary American Fire and Casualty remains in the state to wind
down the affairs of the group.

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 become more difficult. 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. New Jersey passed the Fair
Automobile Insurance Reform Act which was an eight year assessment that began in
1990 and ended in 1997. In order to meet our state imposed assessment
obligations under the Fair Automobile Insurance Reform Act the Corporation has
incurred expenses of $3.3 million in 1997 and $3.6 million in 1996. The
Corporation's future obligations related to this act are minimal as only true-up
payments of less than $.1 million were made in 1998 and remaining future
true-ups are anticipated to be immaterial to the Corporation's results of
operations, financial position and liquidity in future years.

The Unsatisfied Claim and Judgment Fund is another assessment made by the State
of New Jersey. This assessment is based upon estimated future direct premium
written in that state. The Corporation has paid $3.4 million in 1999 for fiscal
year 2000 assessment and has paid $3.2 million, $4.2 million and $4.4 million in
1998, 1997 and 1996, respectively. The Corporation anticipates the future
assessments to be between $3.0 and $4.0 million dollars annually. The
Corporation anticipates future assessments will not materially affect the
Corporation's results of operations, financial position or liquidity.

Recently, the New Jersey State Senate passed an auto insurance reform bill that
mandates a 15% rate reduction for personal auto policies for drivers who agree
not to sue for "pain and suffering" unless they suffer permanent injury in an
accident. The bill was passed by the Assembly and signed by the governor. The
reform bill becomes effective on March 22, 1999. The anticipated impact on the
Corporation is a tradeoff of lower premium rates on personal auto policies for
presumably lower losses on these policies but the degree of offset, if any, is
uncertain at present. As of December 31, 1998, the Corporation had personal auto
net premium written of $114.5 million or 53.1% of total premium that the
Corporation writes in New Jersey. The maximum impact of this reform bill on the
Corporation would have been a decrease in premium of $17.2 million for the year
ended December 31, 1998 if all policyholders made this election on their
policies.

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 three NAIC financial ratios
that were outside the usual range in the last five calendar years.

16


17


ITEM 1. CONTINUED

Beginning in 1994, the NAIC required 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 are in excess of levels that would require
regulatory action.

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 1998, $112.1
million of policyholders' surplus is not subject to restrictions or prior
dividend approval.

EMPLOYEES

At December 31, 1998, the Ohio Casualty Group had approximately 4,050 employees
of which approximately 1,370 were located in Hamilton, Ohio.

YEAR 2000

The Corporation is proceeding on schedule in its phased approach to convert its
computer systems to be Year 2000 compliant. The four phases included in this
approach are: awareness, planning, execution/testing and compliance. Two of the
phases, awareness and planning, are complete and the execution/testing and
compliance phases are substantially complete with only one system left to be
tested.

The Corporation began the awareness phase early in the 1990s, recognizing that
its systems and applications would need significant changes. From that time
forward all system development and major enhancements to existing systems took
Year 2000 processing requirements into consideration. This approach resulted in
some of our systems being converted and compliant long before there was any
business requirement or exposure to processing problems.

During 1995, the Information Systems Department (I/S) began the planning phase.
At that time Year 2000 compliance became a priority project with Project
Managers assigned specifically for converting our systems to be compliant. A
comprehensive inventory of our systems was completed, identifying the critical
date that each system must be compliant and an action plan was put together to
outline that the conversion was completed on time. The Corporation is currently
on schedule with this action plan.

As a result of the planning phase, dedicated staff and resources were assigned
to work on the Year 2000 project. This began our execution/testing phase of the
project which includes addressing the remediation of Year 2000 problems
identified in the planning phase and logical partition (LPAR) compliance
testing. LPAR compliance testing requires an isolated partition within the
computer that runs independently. Essentially it can be considered an entirely
separate computer. The Corporation's LPAR has a dedicated processor, disk and
tape storage. In this environment, data can be migrated forward and tested as
the internal date in the computer is changed to critical dates in 1999 and 2000.
This provides an excellent environment to test applications, system software and
hardware. This involves individual and integrated compliance testing. The first
step verifies that the systems are compliant when they run independently. The

17


18


ITEM 1. CONTINUED

second step verifies compliance when they are integrated with all other systems
with which they interface. Testing was performed throughout 1998 focusing
initially on systems critical to the daily business operation and followed by
all others. The Corporation has six major system areas: commercial lines,
claims, auto, personal property, management/financial reporting and human
resources. All of these areas are required to undergo LPAR compliance testing.
At this time, the auto, commercial lines, claims, personal property and human
resource systems have completed the LPAR compliance testing. The Corporation's
management/financial reporting system area has substantially completed LPAR
compliance testing with only one internal management reporting system left to be
tested. This is targeted for completion by the end of the first quarter 1999.

Following the completion of LPAR compliance testing, all systems will undergo
integrated testing of the production environment. Contingency plans include
compliance reverification of this integrated test early in the third quarter of
1999 and again early in the fourth quarter of 1999.

As of December 31, 1998, the total amount spent to date for I/S related costs on
the Year 2000 project is $2.3 million and the Corporation anticipates minimal
additional I/S related expenses to complete our efforts. These amounts do not
include any costs associated with efforts made to contact third parties or
related to contingency planning. As a result of the Corporation's efforts early
in the 1990s to begin making changes to systems and existing hardware and
software, the Corporation to date has not had to make an expensive effort to
identify and remedy its Year 2000 issues and does not anticipate that it will be
required to make substantial expenditures to address Year 2000 compliance in the
future.

During 1997, the Corporation began the compliance phase. The Year 2000 team is
currently in the process of identifying all significant vendors, suppliers and
agents of the Corporation and is completing the initial contact to obtain
written statements of their readiness and commitment to a date for their Year
2000 compliance. The Corporation will continue to monitor the Year 2000 status
of these entities and develop contingency plans to reduce the possible
disruption in business operations that may result from the failure of third
parties with which the Corporation has business relationships to address their
Year 2000 issues. Identification and initial contact for all significant
third-parties is expected to be complete by the first quarter of 1999 with
follow-up reviews scheduled throughout 1999. Should a third-party with whom the
Corporation transacts business have a system failure due to not being Year 2000
compliant, the Corporation believes this could result in a delay in processing
or reporting transactions of the Corporation, or a potential disruption in
service to its customers, notwithstanding the Corporation's intention to develop
contingency plans to respond to these potential system failures by such third
parties.

The Corporation is also addressing non information technology (non-IT) to ensure
Year 2000 compliance. At December 31, 1998, the Year 2000 team had completed a
preliminary assessment of the non-IT assets. The team identified the material
items that have a risk involving the safety of individuals, or that may cause
damage to property or the environment, or affect revenues. The team reported on
the identified non-IT assets in December 1998 to the Corporation's Executive
Management Team. Remediation and contingency planning is scheduled throughout
1999 with regular updates required to be given to the Executive Management Team.

The Corporation is currently assessing the status of Year 2000 readiness of the
business and assets that it acquired in the acquisition of substantially all the
Commercial Lines Division of Great American Insurance Company on December 1,
1998. For a period of at least 24 months

18


19


ITEM 1. CONTINUED

from the date of the acquisition, GAI will provide computer processing and
communication services to the Corporation in connection with the acquired
business pursuant to an Information Systems Agreement. Thus, the Corporation
will be dependent on GAI to address and remediate Year 2000 issues with respect
to the information technology systems utilized for the business being acquired
by the Corporation. The failure of GAI to satisfactorily correct a material Year
2000 problem in the computer processing systems being used to provide services
to the Corporation in connection with the acquired business could result in a
material adverse effect on the ability of the Corporation to integrate the
acquired business and to operate it on a profitable basis.

The failure to correct a material Year 2000 problem could result in an
interruption in, or a failure of, the normal business operations of the
Corporation including the disruption or delay in premium or claim processing and
the disruption in service to its customers. Also the inability to be Year 2000
compliant of significant third-party providers of the Corporation could result
in an interruption in the normal business operations. Due to the general
uncertainty inherent in the Year 2000 problem, such failures could materially
and adversely affect the Corporation's financial position, results of operations
or liquidity.

The Year 2000 issue is also a concern from an underwriting standpoint regarding
the extent of liability for coverage under various general liability, property
and directors and officers liability products and policies. The Corporation is
managing this concern by directly providing educational information on Year 2000
to insureds and agents; adding clarification and exclusionary language to
certain policies; and by adjusting underwriting practices. The Corporation
believes that minimal coverage may be interpreted to exist under some current
liability and product policies. The Corporation has historically avoided
manufacturing risks which produce computer or computer-dependent products.

The Insurance Services Office (ISO) recently developed policy language that
clarifies that there is no coverage for certain Year 2000 occurrences. The
liability exclusion has been accepted in over 40 states and a companion filing
for property has been accepted in at least 20 states at this time. Several
states have not adopted or approved the property exclusion form citing
specifically that there is no coverage under the current property contracts and
therefore, there is no reason to accept a clarifying endorsement. The
Corporation is currently addressing the year 2000 issue by attaching the ISO
exclusionary language, where approved by regulators, to general liability
policies with a rating classification the Corporation believes could potentially
have Year 2000 losses. The ISO exclusionary language endorsement is included on
all property policies where approved by regulators. These actions should
minimize the Corporation's exposure to Year 2000 losses.

Directors and officers could be held liable if a company in their control fails
to take necessary actions to address any Year 2000 problems and that failure
results in a material financial loss to the Company. The Corporation has written
directors' and officers' liability policies since 1995, with approximately $.5
million in premiums written in 1998. The Corporation is managing its D&O Year
2000 exposure through a combination of underwriting guidelines which address
Year 2000 issues in the application process and reinsurance policies which
provide coverage for any loss in excess of $.3 million.

Management of the Corporation believes it has an effective program in place to
resolve the Year 2000 issue in a timely manner. However, since it is not

which the Corporation could experience interruptions in normal business
operations. These "worst-case scenarios" include: disruption or delay in premium
and claim processing; disruption in service to customers; litigation for Year
2000 related claims, adverse affects on the Corporation's ability to integrate
the acquired business from Great American and loss of electrical, water and
other utility services which could result in a disruption in the Corporation's
services. The amount of potential liability and lost revenue cannot be
reasonably estimated.

IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS

In December 1997, the American Institute of Certified Public Accountants issued
Statement of Position 97-3 "Accounting by Insurance and Other Enterprises for
Insurance-Related Assessments". This statement provides guidance on accounting
for insurance related assessments and required disclosure information. This
statement is effective for fiscal years beginning after December 15, 1998. The
Corporation does not believe that this statement will materially affect the
Corporation's financial statements or disclosures.

In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standard 133 "Accounting for Derivative Instruments and
Hedging Activities." This statement standardizes the accounting for derivative
instruments by requiring those items to be recognized as assets or liabilities
with changes in fair value reported in earnings or other comprehensive income in
the current period. The Corporation expects the adoption of FAS 133 to have an
immaterial impact on the financial results due to its limited use of derivative
instruments. This statement is effective for fiscal quarters of fiscal years
beginning after June 15, 1999 (January 1, 2000 for the Corporation).


ITEM 2. PROPERTIES

The Ohio Casualty Group owns and leases office space in various parts of the
country. The principal office buildings consist of facilities owned in Hamilton,
Ohio and Fairfield, Ohio.


ITEM 3. LEGAL PROCEEDINGS

There are no material pending legal proceedings against the Corporation or its
subsidiaries other than litigation arising in connection with settlement of
insurance claims as described on page 10 and Proposition 103 hearings described
on page 15 and 16.


ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SHAREHOLDERS

There were no matters submitted during the fourth quarter of the fiscal year
covered by this report to a vote of Shareholders through the solicitation of
proxies or otherwise.

MANAGEMENT'S DISCUSSION & ANALYSIS

RESULTS OF OPERATIONS
Net income decreased 38.9% for 1998 to $84.9 million or $2.58 per share
while the combined ratio increased by 1.9 points to 107.2%. Losses were
negatively impacted by catastrophes with $44.6 million of catastrophe losses in
1998 versus $21.4 million in 1997 and $62.2 million in 1996. Underwriting
expenses, as a percentage of earned premium, increased by 2.0% in 1998 compared
with increases of under 1% for both 1997 and 1996. General operating expenses, a
component of underwriting expenses, have increased over the period of 1996 to
1998. The increase in operating expense is primarily due to expenditures for
advertising as a part of the Corporation's efforts to increase name recognition
of its property and casualty companies.

Statutory net premiums written increased $229.7 million for 1998 to
$1.4 billion. $169.2 million of this increase is attributable to the acquisition
of substantially all of Great American Insurance Company's Commercial Lines
Division. The acquisition added $31.6 million in net written premium for the
month of December as well as $137.6 million in net written premium related to
the transfer of the unearned premium reserve. In addition, the Corporation's
premium growth continued to be led by our key agents with an 8% increase in
written premium for the year. The Corporation has established a very successful
key producer program for agencies who are willing to set and achieve goals in
production and other key areas. Excluding Great American, the largest increase
in premium occurred in the personal auto line of business with a 12.3% increase
and the largest premium increase by individual state came in Kentucky with an
$18.7 million increase or 18.8% over 1997.

Net cash produced from operations was $24.6 million compared with cash
produced of $26.4 million in 1997 and cash used of $14.0 million in 1996.
Investing activities produced net cash of $93.5 million in 1998, compared with
$164.0 million in 1997 and $112.7 million in 1996. Total cash produced from
financing activities was $66.9 million in 1998 compared with total cash used of
$131.9 million in 1997 and $75.4 million in 1996. The increase in 1998 compared
to 1997 primarily resulted from borrowing $225 million from the Corporation's
line of credit offset by dividends paid to shareholders and repurchases of
treasury stock. Dividend payments were $57.9 million in 1998 compared with $57.5
million in 1997 and $56.4 million in 1996. Overall, total cash generated in 1998
was $184.9 million, compared with $58.4 million in 1997 and $23.3 million in
1996.
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, 1998, our five-year average return on
equity was 14.3% compared with 15.5% calculated at December 31, 1997 and 13.4%
at December 31, 1996.

PROPERTY AND CASUALTY

As described in more detail in Note 14, the Corporation purchased
substantially all of the Commercial Lines Division of Great American Insurance
Company on December 1, 1998. The acquisition has been treated as a purchase for
accounting purposes. The revenue and profit reported include the division from
the December 1, 1998 acquisition date forward.

33
34
ITEM 14. CONTINUED

The Corporation's strategy in purchasing substantially all of the
Commercial Lines Division of Great American includes broadening its product mix
and adding approximately 1,400 agents to the Corporation's existing agency
plant. From a geographic point of view, the Corporation will increase its
presence in areas where it already does business and add a presence in the
Northeast, a region in which the Corporation had hoped to expand. Finally, the
Corporation anticipates that it will achieve financial benefits through
cross-selling of products, economies of scale and reductions in expenses through
improved processes.

Property and casualty operating income was $74.9 million, $2.27 per
share, in 1998 compared with $97.4 million, $2.84 per share, in 1997 and $66.1
million, $1.88 per share in 1996. Catastrophe losses in 1998 totaled $44.6
million compared with $21.4 million in 1997 and $62.2 million in 1996. There
were 37 separate catastrophes in 1998 compared with 25 catastrophes in 1997 and
39 in 1996. Catastrophe losses added 3.6 points to the combined ratio in 1998
compared with 1.8 points in 1997 and 5.1 points in 1996. 1998 losses were
heavily impacted by wind and hail related losses in Kentucky, Minnesota and
Iowa. 1996 losses were largely due to winter and spring storms in the Midwest.


PERSONAL AUTO

The performance of our personal auto segment was one of the
Corporation's major successes of 1998. Written premiums increased 12.3% to
$521.8 million in 1998 compared to $464.7 million in 1997 and $456.4 million in
1996. The increase is attributable to aggressive advertising efforts aimed at
increasing brand recognition. In addition, the Corporation's key producer
program continues to generate impressive results. Key producers generated a
12.8% increase in written premiums in 1998 compared to 1997. Lastly, the
Corporation offers a number of unique service advantages including "quick
quotes" from our Website, monthly payment option, youthful drivers program,
direct claims reporting and a number of enhanced policy endorsements.

The combined ratio improved to 103.8% in 1998 from 105.4% in 1997 and
110.3% in 1996. This success comes in spite of a slightly higher impact from
catastrophe losses of 1.2% in 1998 compared to .5% in 1997 and .9% in 1996.


COMMERCIAL MULTI PERIL, FIRE & INLAND MARINE

Written premiums increased 9.5% to $225.7 million in 1998 compared to
$206.1 million in 1997 and $195.3 million in 1996. In 1998, $9 million or 4.3%
is attributable to the acquired business from Great American's Commercial
Division. The remaining increase is largely attributable to production from our
key agents, which increased approximately $7.3 million from 1997.

Competition in the commercial segment remains formidable. Consequently,
rates have remained flat while the combined ratio increased in 1998 to 113.5%
from 107.7% in 1997. The combined ratio in 1996 was 115.0%. The combined ratio
was impacted by catastrophe losses which were 4.9% in 1998, 2.5% in 1997 and
8.3% in 1996. Additionally, losses from our auto services products were higher
than anticipated in 1998. The Corporation continues to be selective in the
writing of new business and to reinforce the sound relationships with customers
who appreciate the stability, expertise and added value the Corporation
provides.


GENERAL LIABILITY

Excluding the impact of $2.0 million in written premiums from the Great
American acquisition, written premiums have decreased for the third consecutive
year to $93.1 million in 1998 from $96.7 million in 1997 and $101.8 million in
1996.

While premiums have declined, the combined ratio improved in 1998 to
101.6% compared to 103.0% in 1997. Market conditions remain intensely
competitive, making profitable premium growth difficult to achieve. During this
period of soft pricing the Corporation has maintained its rates, focusing on a
quality book of business. Consequently, the number of policies in force are down
4.2% in 1998 from 1997 while underwriting results have improved.

35

ITEM 14. CONTINUED

COMMERCIAL AUTO

In a market that continues to be exceptionally competitive, the
Corporation's written premium decreased in 1998 by $4.4 million when excluding
$3.2 million in premiums from the Great American acquisition. Although premiums
declined, excluding Great American, the number of insured vehicles increased
during the year and our business shifted from higher premium states to lower
premium states. The majority of the premium decline came in the states of
Pennsylvania and New Jersey.

While the Corporation's combined ratio improved 7.5 points, it was
higher than anticipated at 105.4%. Liability coverage accounted for 66% of the
Corporation's written premium and liability results were satisfactory. Uninsured
motorists and comprehensive claims, however, were $3.8 million above average of
the proceeding two years, accounting for almost 3 points of the combined ratio.


WORKERS' COMPENSATION

Excluding the impact of $8.3 million in written premiums from the Great
American acquisition, written premiums decreased in 1998 by 5.4% to $91.8
million compared to $97.2 million in 1997 and $115.4 million in 1996. The 1998
decrease primarily resulted from bureau-driven rate decreases, extremely
competitive market conditions.

The combined ratio increased 16.6 points in 1998 to 109.6% compared to
93.0% in 1997 and 94.3% in 1996. The increase primarily resulted from adverse
development in case reserves on older large claims.


HOMEOWNERS

Written premiums grew 7.5% to $180.7 million in 1998 compared to $168.2
million in 1997 and $166.5 million in 1996. This increase is led by our key
agents and corresponds with our increase in personal auto insurance. The
Corporation offers a "Fam-Pak" discount for customers combining automobile and
homeowners coverages.

The combined ratio increased to 118.4% from 111.2% in 1997. The
increase is primarily attributable to increased catastrophe losses of 15.2% in
1998 compared to 8.1% in 1997. In general, our homeowners products are offered
as ancillary to our personal auto products.


FIDELITY & SURETY

Written premiums increased 7.6% in 1998 to $37.0 million compared to
$34.4 million in 1997 and 34.5 million in 1996. The increase in 1998 is
primarily driven by contract surety products for construction contractors and is
fueled by a strong economy.

The combined ratio increased to 81.4% in 1998 from 76.5% in 1997 and
73.4% in 1996. Two large losses in 1998 contributed to the increase; however,
the Corporation's combined ratio remains below the industry average of
approximately 87.4%.


STATUTORY SURPLUS

Statutory surplus, a traditional insurance industry measure of strength
and underwriting capacity, was $1,027.1 million at December 31, 1998 compared
with $1,109.5 million at December 31, 1997 and $984.9 million at December 31,
1996. The decrease in 1998 was due to the statutory treatment of goodwill.
Increases in 1997 and 1996 were due primarily to the unrealized gains in our
investment portfolio and net income less dividends paid.

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 1.4 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 comfortably
exceed the necessary capital.

Pennsylvania 7.4% 8.3% 9.4%
Illinois 6.0% 5.2% 5.0%
- ------------------------------------------------

Premiums written increased in both Ohio and Kentucky for the third
consecutive year. This growth has primarily come from the auto and CMP lines of
business. Net written premiums in Ohio totaled $147.1 million in 1998, $129.8
million in 1997 and $123.8 million in 1996. Net written premiums in Kentucky
totaled $118.4 million in 1998, $99.1 million in 1997 and $86.5 million in 1996.

New Jersey has experienced a small decline in premiums written in each
of the last three years. Net premiums written were $215.8 million compared with
$216.0 million in 1997 and $221.2 million in 1996. The reduction in premium
growth is primarily due to a decline in the workers compensation, general
liability and commercial auto lines of business.

Premiums written in Pennsylvania declined during 1998 to $96.5 million
compared with $99.8 million in 1997 and $113.5 million in 1996. This decline
has primarily been driven by competitive pricing conditions in commercial lines.

RESTRUCTURING

In December 1998, the Corporation finalized a restructuring and
reorganization plan. Under the plan, the Corporation will consolidate many of
its branch locations for underwriting and claims over the course of 1999.
Personal lines business centers will be reduced from five to three locations.
Commercial underwriting branches will be reduced from 17 to eight locations and
claims branches will be reduced from 38 to six locations. Workforce reductions
are anticipated to amount to approximately 250 positions. The plan is expected
to generate approximately $14 million in annual pretax savings upon full
implementation in late 1999.

Restructuring charges recorded in 1998 were comprised of expenses
associated with abandoned lease space totaling $10 million or $.30 per share
before-tax and $6.5 million or $.20 per share after-tax.

DISCONTINUED OPERATIONS

During 1995, the Corporation's life operations were discontinued. The
Corporation 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 with
Great Southern Life Insurance Company. The existing blocks of business were
reinsured through a 100% coinsurance arrangement.

Great Southern Life Insurance Company legally replaced Ohio Life as the
primary insurer, subject to the 1995 reinsurance agreement with Ohio Life, on
approximately

36
37


ITEM 14. CONTINUED

95% of the life insurance business as of the fourth quarter of 1998 and
approximately 76% as of the fourth quarter of 1997. As a result of the increased
assumption, the Corporation recognized additional amounts of unamortized ceding
commission of $1.1 million before tax in 1998 and $10.7 million in 1997. There
remains approximately $1.1 million in unamortized ceding commission. This will
continue to be amortized over the remaining life of the policies which have yet
to be assumed by Great Southern Life Insurance Company.

Net income from discontinued operations amounted to $1.9 million or
$.06 per share in 1998 compared with $8.7 million or $.25 per share in 1997 and
$5.2 million or $.15 per share in 1996.


REINSURANCE

In order to preserve capital and shareholder value, Ohio Casualty
Corporation purchases reinsurance to protect the Corporation against large or
catastrophic losses. As a result of the Corporation's acquisition of the
majority of the Commercial Lines Division of Great American Insurance Company,
the Corporation's reinsurance program was expanded to address the additional
concentrations of underwriting exposures. 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. Property reinsurance covers $29.0
million in excess of the retention. The Casualty Per Occurrence contract covers
the Corporation in the event an insured sustains a liability loss in excess of
$1.0 million in a single insured event. Workers' compensation, umbrella and
other casualty reinsurance covers $100.0 million, $50.0 million and $24.0
million respectively in excess of the retention. The Corporation also carries
various facultative reinsurance contracts protecting certain individual risks.

The catastrophe reinsurance contract protects the Corporation against
an accumulation of losses arising from one defined catastrophic occurrence or
series of events. The 1999 catastrophe program, similar to 1998, provides $150.0
million coverage in excess of the Corporation's $25.0 million retention. In
1998, a portion of the catastrophe program was again renewed with a multi-year
placement. The multi-year placements maintain rates, continuity, and each
reinsurers' overall share on the program. Over the last 20 years, there were two
events that triggered coverage under our catastrophe reinsurance contract.
Losses and loss adjustment expenses from the Oakland Fires in 1991 and Hurricane
Andrew in 1992 totaled $35.6 million and $29.8 million, respectively. Both of
these losses exceeded our prior retention amount of $13.0 million. The
Corporation recovered $33.9 million from reinsurers as a result of these events.
Our reinsurance limits are designed to cover exposure to a catastrophic event
expected to occur once every 300 years.

Reinsurance contracts do not relieve the Corporation of its obligation
to the policyholders. The collectibility of reinsurance is subject to the
solvency of the reinsurers. Since the Corporation's reinsurance protection is an
important component in our financial plan, we closely monitor the financial
health and claims settlement performance of each of our reinsurers. Annually,
financial statements are reviewed and various ratios calculated to identify
reinsurers who have ceased to meet our high standards of financial strength. If
any reinsurers fail these tests, they are removed from the program at renewal.
Currently, all domestic reinsurers have an AM Best rating of A or better and the
financial condition of all international reinsurers meet the Corporation's high
standards. Additionally, the Corporation utilizes a large base of reinsurers to
mitigate its concentration risk. In 1998 and 1997 no reinsurer accounted for
more than 10% of total ceded premiums. In 1996, only three reinsurers exceeded
10% of total ceded premiums. Everest Reinsurance Company, MidOcean Reinsurance
Company and Kemper Reinsurance Company accounted for 16.79%, 10.65% and 10.52%
of total ceded premiums respectively. As a result of the Corporation's controls
over reinsurance, uncollectible amounts have not been significant.

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 $2.0
billion at December 31, 1998, $1.5 billion at December 31, 1997 and $1.6 billion
at December 31, 1996.

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 66% contractors, 16% building/premises, 12% mercantile and only 6%
manufacturers. Within the manufacturing category, we have concentrated on the
light manufacturers which further limits our exposure to environmental claims.

Estimated asbestos and environmental reserves are composed of case
reserves, incurred but not reported reserves and reserves for loss adjustment
expense. For 1998, 1997 and 1996, respectively, those reserves were $41.9
million, $40.1 million and $41.0 million. Asbestos reserves were $10.3 million,
$7.0 million and $5.2 million and environmental reserves were $31.5 million,
$33.2 million and $35.7 million for those respective years. These loss estimates
are based on 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. As construed by the
California Supreme Court, the proposition requires premium rate rollbacks for
1989 California policyholders while allowing for a "fair" return for insurance
companies. Even after considering investment income, total returns in California
have been less than would be considered "fair" by any reasonable standard.
During the fourth quarter of 1994, the State of California assessed the
Corporation $59.9 million for Proposition 103. 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 actual commissions and premium taxes
paid. The assessment was revised again in August 1995 to $42.1 million plus
interest. In December 1997, during Administrative Law hearings, the California
Department of Insurance filed two revised rollback calculations. These
calculations indicated roll back liabilities of either $35.9 million or $39.9
million plus interest.

In 1998, the Administrative Law Judge issued a proposed ruling with a
rollback liability of $24.4 million plus interest. Her ruling was sent to the
California Commissioner of Insurance to be accepted, rejected or modified. The
Corporation expected the commissioner to rule sometime after the general
election in November, but he has so far failed to do so. In light of this
failure to rule, the Corporation consulted extensively with outside counsel to
determine the range of liability asserted by the Department. The asserted
rollbacks to date have ranged from $24.4 million to $61.1 million. The
Administrative Law Judge indicates clearly in

38

39

ITEM 14. CONTINUED

her ruling that by her calculation the Corporation would have lost approximately
$1.0 million on 1989 operations if a rollback of $24.4 million were imposed.
Given that conclusion, it is clear that any assessment greater than $24.4
million would strengthen the Corporation's Constitutional argument that this
rollback is confiscatory. Since the Corporation does not believe it is possible
to pinpoint a specific rollback within the California Department of Insurance's
asserted range that is the most probable, the Corporation has established a
contingent liability for Proposition 103 rollback at $24.4 million plus simple
interest at 10% from May 8, 1989. This brings the total reserve to $48.0 million
at December 31, 1998.

The Corporation will continue to challenge the validity of any
rollback. To date, the Corporation has paid $4.8 million in legal costs related
to the withdrawal, Proposition 103 and fair plan assessments.


INVESTMENTS

Consolidated pre-tax investment income from continuing operations
decreased 4.9% to $169.0 million in 1998 compared with $177.7 million in 1997
and $183.3 million in 1996. After-tax investment income totaled $125.8 million
in 1998 compared with $133.6 million in 1997 and $138.6 million in 1996. Pre-tax
and after-tax investment income comparisons are impacted by investments in
municipal bonds, which provide tax free investment income.

Cash flow from investment income has been impacted by our continued
share repurchase program. During 1998, Ohio Casualty Corporation purchased
2,362,900 shares of its common stock at a cost of $100.0 million compared with
1,544,688 shares for $64.9 million in 1997 and 264,600 shares for $9.2 million
in 1996. The Corporation is currently authorized to repurchase 1.1 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 14.6 million shares at an average cost of $27.43 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.

At year end 1998, consolidated investments had a carrying value of $3.6
billion. The excess of market value over cost was $787.9 million, compared with
a $697.6 million excess at year end 1997 and $508.8 million at year end 1996.
The increase in unrealized gains in 1998 and in 1997 was attributable to the
strong performance of our equity and fixed income portfolios. After-tax realized
investment gains from continuing operations amounted to $9.4 million in 1998
compared with $33.0 million in 1997 and $32.3 million in 1996.

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 17,
the Corporation has an interest rate swap with Chase Manhattan Bank covering a
portion of the outstanding balance of our line of credit. At year-end 1998 the
amount covered by the swap was $15.0 million. 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, 1998, Ohio Casualty maintained a $375.4 million mortgage-backed
securities portfolio compared with $347.1 million at December 31, 1997 and
$446.9 million at December 31, 1996. The majority of our mortgage-backed
securities holdings are less volatile planned amortization class, sequential
structures and agency pass-through securities. $9.6, $5.8, $27.0 million of this
portfolio was invested in more volatile bond classes (e.g. interest-only,
super-floaters, inverses) in 1998, 1997 and 1996, respectively.

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 is prudent to remain fully invested at all times, subject
only to our liquidity needs.

Tax exempt bonds were 34.8% of the fixed income portfolio at year-end
1998 versus 39.4% at December 31, 1997 and 34.4% at December 31, 1996. This high
average exposure to municipals reflects our internal tax planning strategy as
well as our belief that municipals are attractive relative to taxable bond
alternatives.

ITEM 14. CONTINUED


Our commitment to a diversified, growth-oriented equity portfolio
remains unchanged. Equity investments have increased as a percentage of our
consolidated portfolio from 23.5% in 1996 to 25.7% at year end 1998. This
increase is largely attributable to market appreciation of existing investments
as opposed to commitment of new funds.


MARKET RISK DISCLOSURES FOR FINANCIAL INSTRUMENTS

Market risk is the risk of loss resulting from adverse changes in
interest rates and market prices. In addition to market risk, the Corporation is
exposed to other risks, including the credit risk related to its financial
instruments and the underlying insurance risk relating to its core business. The
sensitivity analysis below summarizes only the exposure to market risk.

The Corporation's investments are held for purposes other than trading
with an objective of earning relative competitive returns by investing in a
diverse portfolio of high-quality, liquid securities. As a result, the
Corporation minimizes its credit risk.

Interest Rate Risk - The Corporation has exposure to losses resulting
from interest rate risk arising from potential volatility in interest rates. The
Corporation attempts to mitigate its exposure to interest rate risk through
active portfolio management including periodic reviews of our asset and
liability positions. Estimates of cash flows, as well as the impact of interest
rate fluctuations relating to the Corporation's investment portfolio and
revolving line of credit are modeled and reviewed quarterly.

Equity Price Risk - The Corporation's portfolio of marketable equity
securities has exposure to losses resulting from equity price risk arising from
potential volatility in equity market values. The Corporation attempts to
mitigate its exposure to equity price risk by maintaining a portfolio of
investments which are diversified across industries, and concentrations in any
one company or industry are limited by parameters established by senior
management. Market risk is actively managed by analysis of various portfolio
characteristics on a routine basis.

The following table illustrates the hypothetical effect of an increase
in interest rates of 100 basis points (1%) and a 10% decrease in equity values
at December 31, 1998. Prior period disclosures are not required in the initial
year of disclosure. The changes in market rates selected reflect the
Corporation's view of changes which are reasonably possible over a one-year
period. These rates should not be considered a prediction by the Corporation of
future events. This analysis is not intended to provide a precise forecast of
the effect of changes in interest rates and equity prices on the Corporation's
income, cash flow and shareholders' equity. In addition, the analysis does not
take into account any actions the Corporation may take to reduce its exposure in
response to market fluctuations.

Estimated Adjusted Market Value
December 31, 1998 Fair Value as indicated above
- ----------------------------------------------------------------
Interest Rate Risk:
Fixed maturities $2,416 $2,312
Short-term
investments 263 183
Equity Price Risk:
Equity securities 925 832
- ----------------------------------------------------------------
Totals $3,604 $3,327
================================================================

In addition to the above scheduled investments, the Corporation has a
revolving line of credit. An increase in interest rates of one basis point would
result in additional annual interest expense of $2.5 million.

Certain assumptions are inherent in the above analysis. The Corporation
assumes an instantaneous shift in interest rates and equity prices at December
31, 1998 and that the composition of its investment portfolio remains relatively
constant. Also, the Corporation assumes a change in interest rates is reflected
uniformly across all financial instruments even though interest rates on certain
types of instruments may fluctuate or lag behind other instruments.


YEAR 2000

The Corporation is proceeding on schedule in its phased approach to
convert its computer systems to be Year 2000 compliant. The four phases included
in this approach are: awareness, planning, execution/testing and compliance. Two
of the phases, awareness and planning, are complete and the execution/testing
and compliance phases are substantially complete with only one system left to be
tested.

40

41

ITEM 14. CONTINUED

The Corporation began the awareness phase early in the 1990s,
recognizing that its systems and applications would need significant changes.
From that time forward all system development and major enhancements to existing
systems took Year 2000 processing requirements into consideration. This approach
resulted in some of our systems being converted and compliant long before there
was any business requirement or exposure to processing problems.

During 1995, the Information Systems Department (I/S) began the
planning phase. At that time Year 2000 compliance became a priority project with
Project Managers assigned specifically for converting our systems to be
compliant. A comprehensive inventory of our systems was completed, identifying
the critical date that each system must be compliant and an action plan was put
together to outline that the conversion was completed on time. The Corporation
is currently on schedule with this action plan.

As a result of the planning phase, dedicated staff and resources were
assigned to work on the Year 2000 project. This began our execution/testing
phase of the project which includes addressing the remediation of Year 2000
problems identified in the planning phase and logical partition (LPAR)
compliance testing. LPAR compliance testing requires an isolated partition
within the computer that runs independently. Essentially it can be considered an
entirely separate computer. The Corporation's LPAR has a dedicated processor,
disk and tape storage. In this environment, data can be migrated forward and
tested as the internal date in the computer is changed to critical dates in 1999
and 2000. This provides an excellent environment to test applications, system
software and hardware. This involves individual and integrated compliance
testing. The first step verifies that the systems are compliant when they run
independently. The second step verifies compliance when they are integrated with
all other systems with which they interface. Testing was performed throughout
1998 focusing initially on systems critical to the daily business operation and
followed by all others. The Corporation has six major system areas: commercial
lines, claims, auto, personal property, management/financial reporting and human
resources. All of these areas are required to undergo LPAR compliance testing.
At this time, the auto, commercial lines, claims, personal property and human
resource systems have completed the LPAR compliance testing. The Corporation's
management/ financial reporting system area has substantially completed LPAR
compliance testing with only one internal management reporting system left to be
tested. This is targeted for completion by the end of the first quarter 1999.

Following the completion of LPAR compliance testing, all systems will
undergo integrated testing of the production environment. Contingency plans
include compliance reverification of this integrated test early in the third
quarter of 1999 and again early in the fourth quarter of 1999.

As of December 31, 1998, the total amount spent to date for I/S related
costs on the Year 2000 project is $2.3 million and the Corporation anticipates
minimal additional I/S related expenses to complete our efforts. These amounts
do not include any costs associated with efforts made to contact third parties
or related to contingency planning. As a result of the Corporation's efforts
early in the 1990s to begin making changes to systems and existing hardware and
software, the Corporation to date has not had to make an expensive effort to
identify and remedy its Year 2000 issues and does not anticipate that it will be
required to make substantial expenditures to address Year 2000 compliance in the
future.

During 1997, the Corporation began the compliance phase. The Year 2000
team is currently in the process of identifying all significant vendors,
suppliers and agents of the Corporation and is completing the initial contact to
obtain written statements of their readiness and commitment to a date for their
Year 2000 compliance. The Corporation will continue to monitor the Year 2000
status of these entities and develop contingency plans to reduce the possible
disruption in business operations that may result from the failure of third
parties with which the Corporation has business relationships to address their
Year 2000 issues. Identification and initial contact for all significant
third-parties is expected to be complete by the first quarter of 1999 with
follow-up reviews scheduled throughout 1999. Should a third-party with whom the
Corporation transacts business have a system failure due to not being Year 2000
compliant, the Corporation believes this could result in a delay in processing
or reporting


41

42

ITEM 14. CONTINUED


transactions of the Corporation, or a potential disruption in service to its
customers, notwithstanding the Corporation's intention to develop contingency
plans to respond to these potential system failures by such third parties.

The Corporation is also addressing non information technology (non-IT)
to ensure Year 2000 compliance. At December 31, 1998, the Year 2000 team had
completed a preliminary assessment of the non-IT assets. The team identified the
material items that have a risk involving the safety of individuals, or that may
cause damage to property or the environment, or affect revenues. The team
reported on the identified non-IT assets in December 1998 to the Corporation's
Executive Management Team. Remediation and contingency planning is scheduled
throughout 1999 with regular updates required to be given to the Executive
Management Team.

The Corporation is currently assessing the status of Year 2000
readiness of the business and assets that it acquired in the acquisition of
substantially all the Commercial Lines Division of Great American Insurance
Company on December 1, 1998. For a period of at least 24 months from the date of
the acquisition, GAI will provide computer processing and communication services
to the Corporation in connection with the acquired business pursuant to an
Information Systems Agreement. Thus, the Corporation will be dependent on GAI to
address and remediate Year 2000 issues with respect to the information
technology systems utilized for the business being acquired by the Corporation.
The failure of GAI to satisfactorily correct a material Year 2000 problem in the
computer processing systems being used to provide services to the Corporation in
connection with the acquired business could result in a material adverse effect
on the ability of the Corporation to integrate the acquired business and to
operate it on a profitable basis.

The failure to correct a material Year 2000 problem could result in an
interruption in, or a failure of, the normal business operations of the
Corporation including the disruption or delay in premium or claim processing and
the disruption in service to its customers. Also the inability to be Year 2000
compliant of significant third-party providers of the Corporation could result
in an interruption in the normal business operations. Due to the general
uncertainty inherent in the Year 2000 problem, such failures could materially
and adversely affect the Corporation's financial position, results of operations
or liquidity.

The Year 2000 issue is also a concern from an underwriting standpoint
regarding the extent of liability for coverage under various general liability,
property and directors and officers liability products and policies. The
Corporation is managing this concern by directly providing educational
information on Year 2000 to insureds and agents; adding clarification and
exclusionary language to certain policies; and by adjusting underwriting
practices. The Corporation believes that minimal coverage may be interpreted to
exist under some current liability and product policies. The Corporation has
historically avoided manufacturing risks which produce computer or
computer-dependent products.

The Insurance Services Office (ISO) recently developed policy language
that clarifies that there is no coverage for certain Year 2000 occurrences. The
liability exclusion has been accepted in over 40 states and a companion filing
for property has been accepted in at least 20 states at this time. Several
states have not adopted or approved the property exclusion form citing
specifically that there is no coverage under the current property contracts and
therefore, there is no reason to accept a clarifying endorsement. The
Corporation is currently addressing the year 2000 issue by attaching the ISO
exclusionary language, where approved by regulators, to general liability
policies with a rating classification the Corporation believes could potentially
have Year 2000 losses. The ISO exclusionary language endorsement is included on
all property policies where approved by regulators. These actions should
minimize the Corporation's exposure to Year 2000 losses.

Directors and officers could be held liable if a company in their
control fails to take necessary actions to address any Year 2000 problems and
that failure results in a material financial loss to the Company. The
Corporation has written directors' and officers' liability policies since 1995,
with approximately $.5 million in premiums written in 1998. The Corporation is
managing its D&O Year 2000 exposure through a combination of underwriting
guidelines which address Year 2000 issues in the application process and
reinsurance policies which provide coverage for any loss in excess of $.3
million.

42

43

ITEM 14. CONTINUED


Management of the Corporation believes it has an effective program in
place to resolve the Year 2000 issue in a timely manner. However, since it is
not possible to anticipate all possible future outcomes, especially when third
parties are involved, there could be "worst-case scenarios" in which the
Corporation could experience interruptions in normal business operations. These
"worst-case scenarios" include: disruption or delay in premium and claim
processing; disruption in service to customers; litigation for Year 2000 related
claims and adverse affects on the Corporations ability to integrate the acquired
business from Great American. The amount of potential liability and lost revenue
cannot be reasonably estimated.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(All dollar amounts in thousands, except share data, unless otherwise stated)

NOTE 1 -- ACCOUNTING POLICIES

A. NATURE OF BUSINESS

Ohio Casualty Corporation is a property and casualty insurer whose primary
products consist of insurance for personal auto, commercial property,
homeowners, workers' compensation and other miscellaneous lines. The Corporation
operates through the independent agency system in over 40 states. Of net premium
written, approximately 16.6% was generated in the State of New Jersey, 11.3% in
Ohio and 9.1% in Kentucky.

B. PRINCIPLES OF CONSOLIDATION

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. The results of operations of the
acquisition of certain assets and liabilities of the Great American Insurance
Company Commercial Lines Division ("GAI") have been included in the consolidated
financial statements of the Corporation since the date of acquisition, December
1, 1998 (See Note 14). All significant inter-company transactions have been
eliminated. All dollar amounts except share and per share data are in thousands
of dollars.

C. INVESTMENTS

Investment securities are 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.

Short-term investments include commercial paper and notes with original
maturities of 90 days or less and are stated at fair value. 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.

D. PREMIUMS

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.


E. ACQUISITION COSTS

Acquisition costs incurred at policy issuance net of applicable ceding
commissions are deferred and amortized over the term of the policy. Acquisition
costs deferred are commissions, brokerage fees, salaries and benefits, and other
underwriting expenses to include allocations for inspections, taxes, rent and
other expenses as deemed appropriate. Deferred policy acquisition costs are
reviewed periodically to determine that they do not exceed recoverable amounts,
including anticipated investment income.

F. PROPERTY AND EQUIPMENT

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. As of January 1, 1998, the Corporation adopted
Statement of Position (SOP) 98-1 and began capitalizing costs incurred to
internally develop software products used in the Corporation's operations. The
Corporation amortizes these costs on a straight-line basis over the estimated
useful life of the product, generally not to exceed five years. Unamortized
software costs and accumulated amortization in the consolidated balance sheet at
December 31, 1998 were $8,013 and $184.

G. GOODWILL

The Corporation records goodwill for the excess of cost over the fair value of
net assets acquired. Goodwill is amortized on a straight-line basis over a
twenty-five year period. Goodwill will be evaluated periodically as events or
circumstances indicate a possible inability to recover their carrying amount.
Such evaluation will be based on various analyses, including cash flow and
profitability projections that incorporate, as applicable, the impact on
existing company businesses. The analyses will necessarily involve significant
management judgments to evaluate the capacity of an acquired business to perform
within projections. If future undiscounted cash flows are insufficient to
recover the carrying amount of the asset, an impairment loss will be recognized.

H. 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.

Liabilities for future policy benefits are computed based on contract terms
and issue dates using interest rates ranging from 3 1/2% to 8 3/4%, select and
ultimate mortality experience and industry withdrawal experience. Interest rates
on $14,884 of such liabilities in 1998, $24,611 in 1997 and $230,843 in 1996 are
periodically adjusted based on market conditions. Fair value is determined by
discounting cash flows at current market interest rates.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(All dollar amounts in thousands, except share data, unless otherwise stated)

I. DEFERRED INCOME TAXES

The Corporation records deferred tax assets and liabilities based on temporary
differences between the financial statement and tax bases of assets and
liabilities using enacted tax rates in effect in the year in which the
differences are expected to reverse.

J. STOCK OPTIONS

The Corporation accounts for stock options issued to employees in accordance
with Accounting Principles Board Opinion (APB) No. 25, "Accounting for Stock
Issued to Employees". Under APB 25, the Corporation recognizes expense based on
the intrinsic value of options.

K. USE OF ESTIMATES

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.

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.

The above medical trend rates assumed for 1998, 1997 and 1996 were assumed
to decrease to the ultimate rate of 5% in 2, 3 and 4 years respectively. The
postretirement plan measurement date is October 1 for 1998, 1997 and 1996.

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, 1998 by approximately $ 19,669 and increase the postretirement
benefit cost for 1998 by $2,032. Likewise, decreasing the assumed health care
cost trend by 1 percentage point in each year would decrease the accumulated
postretirement benefit obligation as of December 31, 1998 by approximately
$12,785 and decrease the postretirement benefit cost for 1998 by $1,250.

The Corporation's health care plan is a predominately managed care plan.
Retired employees continue to be eligible to participate in the health care and
life insurance plans. Employee contributions to the health care plan have been
established as a flat dollar amount with periodic adjustments as determined by
the Corporation. The health care plan is unfunded. Benefit costs are accrued
based on actuarial projections of future payments. There are currently 3,261
active employees and 1,416 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.

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, directors, and other full time salaried
employees 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 either 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, 1998,
868,289 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. At December 31, 1998, there were no
outstanding stock appreciation rights.

Restricted stock awards are occasionally issued by the Corporation. The
common shares covered by a restricted stock award may be sold or otherwise
disposed of only after a minimum of six months from the grant date of the award.
The difference between issue price and the fair market value on the date of
issuance is recorded as compensation expense. The amount of compensation expense
recognized in 1998 related to restricted stock awards was $387 and $345 in 1997
before tax. There were no restricted stock awards in 1996. Currently there are
15,312 shares of restricted stock outstanding.

The Corporation also issues, at its discretion, dividend payment rights in
connection with the grant of stock options. These rights entitle the holder to
receive, for each dividend payment right, an amount in cash equal to the
aggregate amount of dividends that the Corporation has paid on each common share
from the date on which such right becomes effective through the payout date. One
third of these rights becomes vested on each anniversary after the grant.
Dividends accrue and payments are made when the rights are fully vested by the
rightholder. The Corporation recognizes compensation expense accordingly. The
amount of compensation expense related to dividend payment rights recognized in
1998 was $551 and $517 in 1997 before tax. As of December 31, 1998, 313,684
dividend payment rights were outstanding.

The Corporation continues to elect APB 25 for recognition of stock-based
compensation expense. Under APB 25, expense is recognized based on the intrinsic
value of the options. 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 1998, 1997 and 1996,
respectively: dividend yield of 4.5% for 1998, 1997 and 1996, expected
volatility of 26.7% for 1998, 26.1% for 1997 and 25.3% for 1996, risk free
interest rate of 5.63%, 6.87% and 6.34%, and expected life of 8 years. The
following table summarizes information about the stock-based compensation plan
as of December 31, 1998, 1997 and 1996, and changes that occurred during the
year:

At year end 1998, 379,684 options were outstanding with an average
remaining contractual life of 7.94 years and weighted exercise price of $40.53.
Of the amount outstanding, 159,681 were exercisable with a weighted average
exercise price of $36.90. At year end 1997, 262,494 options were outstanding
with an average remaining contractual life of 8.35 years and a weighted exercise
price of $37.38. Of the amount outstanding, 81,493 were exercisable with a
weighted average exercise price of $34.05. At year end 1996, 172,500 options
were outstanding with an average remaining contractual life of 8.49 years and a
weighted exercise price of $33.84. Of the amount outstanding, 51,500 were
exercisable with a weighted average exercise price of $31.23.

Had the Corporation adopted FAS 123, the amount of compensation expense
that would have been recognized in 1998, 1997 and 1996 respectively, would be
$1,164, $755 and $350. The Corporation's net income and earnings per share would
have been reduced to the pro forma amounts disclosed below:

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 Corporation evaluates the financial condition of its reinsurers
and monitors concentrations of credit risk to minimize its exposure to
significant losses from reinsurer insolvencies. The following amounts are
reflected in the financial statements as a result of reinsurance ceded:



1998 1997 1996
- ---------------------------------------------------------------

Ceded premiums earned,
presented net $ 35,334 $ 32,169 $ 30,534

Reserve for future policy
benefits
Reserve for loss adjustment 25,518 34,148 280,002
expenses 8,707 7,794 8,833


Annuities are purchased from other insurers to pay certain claim
settlements. These payments are made directly to the claimants; 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 claim reserves are presented net of the related annuities on the
Corporation's balance sheet. The total amount of unpaid annuities was $24,155,
$25,123 and $25,139 at December 31, 1998, 1997 and 1996, 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 assets of the fixed income portfolio are not carried on
the Corporation's balance sheet as these are assets of Employers' Reassurance
Corporation. 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. As the market value fluctuates from this amount, Ohio
Casualty is required to make up any deficiency and is entitled to receive any
excess. Accordingly, the Corporation accrues any deficiency or excess in market
value over the guaranteed amount of $163,615. This results in either investment
income or loss and is recorded in earnings of the current period. At December
31, 1998, the market value of the account exceeded the $163,615 required balance
by $1,356 compared with excesses of $2,080 in 1997 and $699 in 1996. The annual
interest obligation of 7.25% was also being adequately serviced by the portfolio
assets.

=============================================================


As a result of favorable development in estimates for insured events of
prior years, the incurred related to prior years shows a favorable
development. The following table presents catastrophe losses incurred and
the respective impact on the loss ratio:



1998 1997 1996
- -----------------------------------------------------------

Incurred losses $44,595 $21,389 $62,189
Loss ratio effect 3.6% 1.8% 5.1%



In 1998, 1997 and 1996 there were 37, 25 and 41 catastrophes respectively.
The largest catastrophe in each year was $7,300, $4,600 and $13,700 in incurred
losses. Additional catastrophes with over $1,000 in incurred losses numbered 14,
3 and 10 in 1998, 1997 and 1996.

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 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 asbestos and environmental reserves are composed of case reserves,
incurred but not reported reserves and reserves for loss adjustment expense. For
1998, 1997 and 1996, respectively, total case, incurred but not reported and
loss adjustment expense reserves were $41,898, $40,121 and $40,956. Asbestos
reserves were $10,364, $6,966 and $5,215 and environmental reserves were
$31,534, $33,155 and $35,741 for those respective years.

NOTE 10 -- EARNINGS PER SHARE
During 1997, the Corporation adopted Statement of Financial Accounting Standard
128 "Earnings Per Share". Basic earnings per share is computed using weighted
average number of common shares outstanding. Diluted earnings per share is
computed similar to basic earnings per share except that the weighted average
number of shares outstanding is increased to include the number of additional
common shares that would have been issued if all dilutive outstanding stock
options would have been exercised. All prior periods were recalculated under the
new definition of basic and diluted earnings per share. Basic and diluted
earnings per share are summarized as follows:



1998 1997 1996
- ---------------------------------------------------------------

Income from continuing
operations $83,011 $130,392 $97,228
Average common shares
outstanding - basic 32,904 34,228 35,247
Basic income from continuing

Diluted income from

At December 31, 1998, 3,000 purchase warrants and 103 stock options were
not included in earnings per share calculations for 1998 as they were
antidilutive.

NOTE 13 -- SEGMENT INFORMATION
In 1998, the Corporation adopted Statement of Financial Accounting Standard 131,
"Disclosures about Segments of an Enterprise and Related Information." This
statement supersedes Statement of Financial Accounting Standard 14, "Financial
Reporting for Segments of a Business Enterprise" and replaces the industry
segment approach with a management segment approach in identifying reportable
segments. The management segment approach focuses on financial information that
the Corporation's decision makers use to make decisions about the operating
segments. The accounting policies of the property and casualty segments are
based upon statutory accounting practices. Statutory accounting principles
differ from generally accepted accounting principles primarily by deferred
policy acquisition costs, required statutory reserves, assets not admitted for
statutory reporting, California Proposition 103 reserve and deferred federal
income taxes.

The Corporation has determined its reportable segments based upon its
method of internal reporting which is organized by product line. The property
and casualty segments are personal automobile, commercial automobile,
homeowners, workers' compensation, fidelity and surety, general liability and
commercial property. These segments generate revenues by selling a wide variety
of personal, commercial and surety insurance products. The Corporation also has
an all other segment which derives its revenues from premium financing,
investment income, royalty income and discontinued life insurance operations.
The Corporation writes business in over 40 states in conjunction with the
independent agency system.

Each segment of the Corporation is managed separately. The property and
casualty segments are managed by assessing the performance and profitability of
the segments through analysis of industry financial measurements including loss
and loss adjustment expense ratios, combined ratio, premiums written,
underwriting gain/loss and the effect of catastrophe losses on the segment. The
following tables present this information by segment as it is reported
internally to management. Asset information by reportable segment is not
reported, since the Corporation does not produce such information internally.

NOTE 14 -- ACQUISITION OF COMMERCIAL LINES BUSINESS
On December 1, 1998, the Corporation acquired substantially all of the
Commercial Lines Division of Great American Insurance Company ("GAI"), an
insurance subsidiary of the American Financial Group, Inc. As part of the
transaction, the Corporation assumed responsibility for 650 employees of GAI's
Commercial Lines Division, as well as relationships with 1,700 agents. The major
lines of business included in the sale are workers' compensation, commercial
multi-peril, umbrella and commercial auto. Four commercial operations as well as
all California business and all pre-1987 environmental claims were excluded from
the transaction.

Under the asset purchase agreement, the Corporation assumed $645,813 of
commercial lines insurance liabilities, $62,639 in other liabilities and
acquired $287,900 of investments, $1,500 in cash and $119,052 in other assets.
This resulted in an assumption by the Corporation of a net statutory-basis
liability of $300,000 plus warrants to purchase 3 million shares of Ohio
Casualty Corporation common stock at a price of $45.01. In addition, if the
annualized production from the transferred agents at the end of eighteen months
equals or exceeds the production in the twelve months prior to closing, GAI will
receive an additional $40,000. This bonus payment grades down ratably where if
eighteen-month annualized production equals 71% or less of previous production,
no bonus payment is


57

ITEM 14. CONTINUED

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(All dollar amounts in thousands, except share data, unless otherwise stated)
required. The bonus payment will be accrued as additional goodwill when minimum
contingency is achieved.

The transaction was accounted for using the purchase method of accounting.
The Corporation has recorded goodwill of $309,237 relating to this transaction,
consisting of $285,517 of net liabilities assumed under generally accepted
accounting principles, $21,138 in warrants given and $2,582 in acquisition
expenses. Deferred policy acquisition costs of $37,371 were also recorded as a
result of the transaction. The Corporation follows the practice of allocating
purchase price to specifically identifiable intangible assets based on their
estimated values as determined by appropriate valuation methods. In the GAI
acquisition, no allocation of purchase price was made to specifically
identifiable intangible assets other than goodwill and deferred policy
acquisition costs as the Corporation believes it did not acquire any other
significant specifically identifiable intangible assets.

The warrants which were issued in connection with the transaction provide
for the purchase of the Corporation's common stock at $45.01 per share and
expire in December 2003. The warrants may be settled through physical or net
share settlement and thus have been recorded as equity in the financial
statements at their estimated fair value. Estimated fair value was determined
based on a third party appraisal of the warrants.



The following table presents the unaudited proforma results of operations
had the acquisition occurred at the beginning of each year.

Revenues $1,750,528 $1,775,556
Net income 58,866 130,206
Diluted earnings per
share 1.79 3.80



NOTE 15 -- RESTRUCTURE CHARGE
During December 1998, the Corporation adopted a plan to restructure its branch
operations. To continue in the Corporation's efforts to reduce expenses,
personal lines business centers will be reduced from five to three locations.
Underwriting branch locations will be reduced from seventeen to eight locations
and claims branches will be reduced from thirty-eight to six locations. The
Corporation recognized $10,000 in expense in its income statement to reflect
one-time charges related to its branch office consolidation plan. These charges
consisted solely of future contractual lease payments related to abandoned
facilities. The activities under the plan are expected to be completed in 1999.


NOTE 16 -- STATUTORY ACCOUNTING INFORMATION
The following information has been prepared on the basis of statutory accounting
principles which differ from generally accepted accounting principles. The
principal differences relate to deferred acquisition costs, required statutory
reserves, assets not admitted for statutory reporting, California Proposition
103 reserve, goodwill and deferred federal income taxes.



1998 1997 1996
- ------------------------------------------------------------------

Property and

Statutory net income $ 82,044 $ 142,457 $ 104,137
Statutory policyholders'
surplus 1,027,105 1,109,517 984,859
Life Insurance
Statutory net income 6,675 29,794 4,885
Statutory policyholders'
surplus 14,943 29,971 58,511


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 statutory statement of
operations. Following this same treatment, during 1997 and 1998 the principal
reduction in the Proposition 103 liability was taken as an increase to statutory
surplus and not included in the 1997 or 1998 statutory statements of operations.

For statutory purposes, goodwill related to the GAI acquisition was taken
as a direct charge to surplus.

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, 1998, approximately $112,129 of retained earnings are
not subject to restriction or prior dividend approval requirements.


NOTE 17 -- BANK NOTE PAYABLE
During 1997, the Corporation signed a credit facility that makes available a
$300,000 revolving line of credit. This line of credit was accessed in 1997 to
refinance the outstanding term loan balance the Corporation had at that time. In
1998, the line of credit was used for capital

58
59
ITEM 14. CONTINUED

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(All dollar amounts in thousands, except share data, unless otherwise stated)

infusion of $200,000 into the property and casualty subsidiaries due to the
acquisition. The line of credit was again accessed during 1998 for the purchase
of a building and to purchase treasury shares. The credit agreement contains
financial covenants and provisions customary for such arrangements. The
agreement expires in October 2002, with any outstanding loan balance due at that
time. The revolving line of credit maintains an interest rate swap that existed
on the previous term loan. The effect of the swap agreement was to establish a
fixed rate of 6.34% on $20,000 of the outstanding balance converted to the
revolving line of credit. The remaining balance and any additional borrowings
under the line of credit bear interest at a periodically adjustable rate (5.82%
at December 31, 1998). 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 $3,547, $3,147 and
$3,769 in 1998, 1997 and 1996, respectively. Under the loan agreement, the
maximum permissible consolidated funded debt cannot exceed 30% of consolidated
tangible net worth.

NOTE 18 -- CALIFORNIA WITHDRAWAL
Proposition 103 was passed in the State of California in 1988 in an attempt to
legislate premium rates for that state. As construed by the California Supreme
Court, the proposition requires premium rate rollbacks for 1989 California
policyholders while allowing for a "fair" return for insurance companies. 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 assessed the Corporation $59,867
for Proposition 103. In February 1995, California revised this billing to
$47,278 due to California Senate Bill 905 which permits reduction of the
rollback due to actual commissions and premium taxes paid. The assessment was
revised again in August 1995 to $42,100 plus interest. In December 1997, during
Administrative Law hearings, the California Department of Insurance filed two
revised rollback calculations. These calculations indicated rollback liabilities
of either $35,900 or $39,900 plus interest.

In 1998, the Administrative Law Judge finally issued a proposed ruling with a
rollback liability of $24,428 plus interest. Her ruling was sent to the
California Commissioner of Insurance to be accepted, rejected or modified. The
Corporation expected the commissioner to rule sometime after the election in
November, but he has so far failed to do so. In light of this failure to rule,
the Corporation consulted extensively with outside counsel to determine the
range of liability asserted by the Department. The asserted rollbacks to date
have ranged from $24,428 to $61,197. The Administrative Law Judge indicates
clearly in her ruling that by her calculation the Corporation would have lost
approximately $1,000 on 1989 operations if a rollback of $24,428 were imposed.
Given that conclusion, it is clear that any assessment greater than $24,428
would strengthen the Corporation's Constitutional argument that this rollback is
confiscatory. Since the Corporation does not believe it is possible to pinpoint
a specific rollback within the California Department of Insurance's asserted
range that is the most probable, the Corporation has established a contingent
liability for Proposition 103 rollback at $24,428 plus simple interest at 10%
from May 8, 1989. This brings the total reserve to $48,043 at December 31, 1998.

The Corporation will continue to challenge the validity of any rollback. To
date, the Corporation has paid $4,755 in legal costs related to the withdrawal,
Proposition 103, and Fair Plan assessments.

In December 1992, the Corporation stopped writing business in California due to
a lack of profitability and a difficult regulatory environment. In April 1995,
the California Department of Insurance gave final approval for withdrawal.
Currently, subsidiary American Fire and Casualty remains in the state to wind
down the affairs of the group.

NOTE 19 -- SHAREHOLDER RIGHTS PLAN
In December 1989, the Board of Directors adopted a Shareholder Rights Plan (the
Plan) declaring a dividend of one-half of one Common Share Purchase Right,
expiring in 2009, for each outstanding share of common stock. The Plan is
designed to deter coercive or unfair takeover tactics and to prevent a person or
persons from gaining control of the Corporation without offering a fair price to
all shareholders.

Under the terms of the Plan, each whole right entitles the registered
holder (except the acquirer) to purchase from the Corporation one share of
common stock at a price of $250 per share, subject to adjustment. Each right
entitles its holder to purchase at the right's then current exercise price, a
number of the Corporation's common shares having a market value of twice such
price. The rights become exercisable for a 60 day period commencing 11 business
days after a public announcement that a person or group has acquired shares
representing 20 percent or more of the outstanding shares of common stock,
without the prior approval of the board of directors; or 11 business days
following commencement of a tender or exchange of 20 percent or more of such
outstanding shares of common stock.

If after the rights become exercisable, the Corporation is involved in a
merger, other business consolidation or 50 percent or more of the assets or
earning power of the Corporation is sold, the rights will then entitle the
rightholders, upon exercise of the rights, to receive shares of common stock of
the acquiring company with a market value equal to twice the exercise price of
each right.

59
60
ITEM 14. CONTINUED

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(All dollar amounts in thousands, except share data, unless otherwise stated)

The Corporation can redeem the rights for $0.01 per right at any time prior
to becoming exercisable.


NOTE 20 -- DISCONTINUED OPERATIONS (LIFE INSURANCE)
Discontinued operations include the operations of Ohio Life, a subsidiary of the
Ohio Casualty Insurance Company.

During 1995, the Corporation committed to a plan to exit the life insurance
business. On October 2, 1995, the Corporation 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 ("Great Southern"). 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. During the fourth quarter of 1997,
Great Southern legally replaced Ohio Life as the primary insurer for
approximately 76% of the life insurance policies subject to the 1995 agreement.
As a result of this assumption, fourth quarter of 1997 net income was positively
impacted by a partial recognition of unamortized ceding commission. The
after-tax impact was an increase to net income of $5,300. At December 31, 1998,
Great Southern had assumed 95% of the life insurance policies subject to the
1995 agreement. As a result, the Corporation recognized an additional amount of
unamortized ceding commission of $1,093 before tax during the fourth quarter
1998. There remains approximately $1,093 in unamortized ceding commission. This
will continue to be amortized over the remaining life of the underlying
policies.

Great Southern Life Insurance Company and Employers' Reassurance
Corporation have entered into a modified coinsurance arrangement whereby all
Ohio Life policies that were assumed by Employers' Reassurance are, in turn,
retroceded to Great Southern Life Insurance Company. This gives the Corporation
additional protection since the Corporation would first look for recovery from
Employers' Reassurance which is rated A++ by A.M. Best. As part of the
agreement, Americo Life Inc., the parent of Great Southern Life, acts as the
third party administrator for Ohio Life for all unassumed policies. This
arrangement lasts until the policies are assumed or lapse. Under the marketing
agreement, Great Southern was permitted to market life insurance products
through the Corporation's independent agency distribution system. This agreement
was terminated in 1996 by mutual consent of the parties.
Results of the discontinued life insurance operations for the years ended
December 31 were as follows:

NOTE 21 -- NEW ACCOUNTING STANDARDS
In December 1997, the American Institute of Certified Public Accountants issued
Statement of Position 97-3 "Accounting by Insurance and Other Enterprises for
Insurance-Related Assessments". This statement provides guidance on accounting
for insurance related assessments and required disclosure information. This
statement is effective for fiscal years beginning after December 15, 1998. The
Corporation does not believe that this statement will materially affect the
Corporation's financial statements or disclosures.

In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standard 133 "Accounting for Derivative Instruments and
Hedging Activities." This statement standardizes the accounting for derivative
instruments by requiring those items to be recognized as assets or liabilities
with changes in fair value reported in earnings or other comprehensive income in
the current period. The Corporation expects the adoption of FAS 133 to have an
immaterial impact on the financial results due to its limited use of derivative
instruments. This statement is effective for fiscal quarters of fiscal years
beginning after June 15, 1999 (January 1, 2000 for the Corporation).
