                     OHIO CASUALTY CORPORATION AND SUBSIDIARIES
                     NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                  (UNAUDITED)

NOTE I - RECENTLY ISSUED ACCOUNTING STANDARDS

During the quarter, the Corporation adopted 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.  In accordance with 
SOP 97-3, the Corporation accrued a liability for insurance assessments of 
$2.3 million net of tax.  This was recorded as a change in accounting method.

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).

NOTE II - 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.  Basic and diluted earnings per share are summarized as 
follows:

                                                  Three months ended
                                                       March 31

                                                ----                ----

operations per weighted average share         $   .38             $   .92

NOTE III - INTERIM ADJUSTMENTS

It is believed that all material adjustments necessary to present a fair 
statement of the results of the interim period covered are reflected in this 
report.  The operating results for the interim periods are not necessarily 
indicative of the results to be expected for the full year.  These statements 
should be read in conjunction with the financial statements and notes thereto 
in the Corporation's 1998 Form 10-K, Item 14.

NOTE IV  -- 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 of March 31, 1999 
and 1998 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 V - 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 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.

NOTE VI - RESTRUCTURING 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 expenses 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 by year-end 1999

ITEM 2.  Management's  Discussion  and  Analysis  of  Financial  Condition 
- -------  and  Results of Operations
         -----------------------------------------------------------------
Property and casualty pre-tax underwriting losses for the quarter ended March 
31, 1999 were $23.4 million, $.75 per share, compared with $6.0 million, $.18 
per share for the same period in 1998.  Gross premiums for the first three 
months of 1999 increased 12.3% for all lines of business excluding the effect 
of $76.5 million in gross premium written from the GAI acquisition.  Commercial 
lines decreased .3% and personal lines increased 21.6% from the same period 
last year excluding the effects of the GAI acquisition.  Property and casualty 
net premiums increased 6.3% for the first quarter of 1999 from the same period 
a year ago excluding $65.8 million related to the GAI acquisition.

Premium from Key Agents grew 9.5% over the same period of 1998.  Key Agents 
work closely with the Corporation to establish goals to increase profitability, 
growth and retention.  Non-key active agents grew 8.2% over 1998.  These 
together with new appointments brings total active agent premium growth to 
11.4% for 1999.

New Jersey is our largest state with 18.8% of total net premiums written 
during the quarter.  Legislation passed in 1992 requires automobile insurers 
operating in the state to accept all risks that meet underwriting guidelines 
regardless of risk concentration.  This leads to a greater risk concentration 
in the state than the Corporation would otherwise accept.  New Jersey also 
requires assessments to be paid for the New Jersey Unsatisfied Claim and 
Judgment Fund (UCJF).  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 in 1998.  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 reform bill became effective on March 22, 1999, and all 
new policies and renewal policies written on or after that date reflect the 
15% rate reduction.  Current policyholders electing to cancel their current 
policy and renew with the effects of the rate rollback have so far been 
insignificant.  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 March 31, 1999, the Corporation had personal auto net premium written of 
$46.2 million or 62.0% of total premium that the Corporation writes in New 
Jersey compared with $114.5 million or 53.1% at year-end 1998.  The projected 
impact of this reform bill on the Corporation would have been a decrease in 
premium of $6.9 million and $17.2 million for the periods ended March 31, 1999
and December 31, 1998 respectively.

The combined ratio for the first three months increased 1.5 points to 104.9% 
from 103.4% from the same period last year.  The three-month combined ratio 
for homeowners increased 24.3 points to 130.2% from 105.9% in the same period 
last year.  This increase is due to an increase in non-catastrophe weather 
related losses in 1999 compared with the same period of 1998.  Personal 
automobile, the Corporation's largest line, recorded a 1999 three-month 
combined ratio of 100.5% decreasing from 101.4% in 1998.  Workers' compensation 
combined ratio for the first three months of 1999 decreased 39.6 points to 
91.5% from 131.1% during the same period last year.  The decrease in the 
workers' compensation ratio is due to reserve increases in 1998 from the 
additional development of certain pre-existing claims that have leveled off in 
the first quarter 1999.

The general liability combined ratio decreased during the first quarter 1999 
to 78.3% from 91.0% in 1998.  This reduction is largely due to favorable loss 
development during the first quarter of 1999.  The combined ratio for CMP, 
fire and inland marine increased 15.2 points to 118.6% from 103.4% during 
March 1999.  This increase is due largely to an increase in frequency due to 
non-catastrophe weather related losses as well as adverse development in the 
first quarter of 1999 compared with the same period last year.

The first quarter catastrophe losses were $5.6 million and accounted for 1.8 
points on the combined ratio.  This compares with $3.0 million and 1.0 point 
for the same period in 1998.  The effect of catastrophes on
                                     
                                     10

the Corporation's results cannot be accurately predicted.  Severe weather 
patterns can have a material adverse impact on the Corporation's results.  
During the first quarter of 1999 there were 5 catastrophes compared with 8 
catastrophes in the first quarter of 1998.  The largest catastrophe in each 
quarter was $2.4 million and $1.7 million, respectively, in incurred losses.  
For additional disclosure 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 the Corporation's 1998 Form 10-K.

For the quarter, property and casualty before tax investment income was $42.5 
million, $1.36 per share, decreasing slightly from $43.2 million, $1.29 per 
share, for the same period last year.  The effective tax rate on investment 
income for the first quarter of 1999 was 25.1% compared with 24.4% for the 
comparable period in 1998. 

Net cash used by operations was $61.8 million for the first three months of 
the year compared with net cash generated of $20.2 million for the same period 
in 1998.  This change is due to a decrease in net income of $19.9 million from 
the same period last year, an increase in agents balances receivable, largely
caused by a shift from a six month billing period to a twelve month billing 
period and payment of $40.0 million for other liabilities assumed from GAI. 
Shareholder dividend payments were $14.4 million in the first three months of 
1999 compared with $14.8 million for the same period of 1998.

In 1995, the Corporation reinsured substantially all of its life insurance and 
related businesses to Great Southern Life Insurance Company.  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 of 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.  Additional information related to 
the discontinued life insurance operations is included in Item 14, Note 20 
Discontinued Operations on page 60 of the Corporation's 1998 Form 10-K.

All of the Corporation's below investment grade securities 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 62 corporate borrowers in approximately 39 
industries.

Investments in below investment grade securities have greater risks than 
investment 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.  Current liquidity needs are expected to be met by
scheduled bond maturities, even if the below investment grade and unrated
securities are excluded.  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.

For further discussion of the Corporation's investments, see Item 1 of the 
Corporation's 1998 Form 10-K for the year ended December 31, 1998.

In 1994, the National Association of Insurance Commissioners developed a risk-
based capital model to establish standards which will compare insurance 
company statutory surplus to required minimum capital based on 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 
reserve and premiums written risks.  Based on current calculations, all of the 
Ohio Casualty Group companies are in excess of the necessary capital to 
conform with the risk-based capital model.

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 were 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 permitted 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 $48.7 million at March 31, 1999.

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.

During the first quarter, Ohio Casualty continued its share repurchase 
program.  The total number of shares acquired during the quarter was 517,100, 
at an average price of $40 per share.  The Company has remaining authorization 
to repurchase 546,812 additional shares.
                                     
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.  All 
phases, including awareness, planning, execution/testing and compliance 
verification are complete; however, we continue testing to ensure utmost 
preparedness.

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, and at this time, all have 
completed the LPAR compliance testing.

All systems will undergo integrated testing of the production environment.  In 
1999, contingency plans include compliance reverification of this integrated 
test early in the third quarter 1999 and again early in the fourth quarter 
1999.

As of March 31, 1999, the total amount spent to date for I/S related costs on 
the Year 2000 project is $2.4 million and the Corporation anticipates minimal 
additional I/S related expenses.   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 
has identified all significant vendors, suppliers and agents of the 
Corporation and has completed 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.  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 

                                     13
  14
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.  The Year 2000 team has completed an assessment 
of the non-IT assets; and, 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 no coverage exists; however, 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 
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 

                                     14

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.

From time to time, the Company may publish forward looking statements relating 
to such matters as anticipated financial performance, business prospects and 
plans, regulatory developments and similar matters.  The statements contained 
in this Management's Discussion and Analysis of Financial Condition and 
Results of Operations that are not historical information, are forward looking 
statements.  The Private Securities Litigation Reform Act of 1995 provides a 
safe harbor under The Securities Act of 1933 and The Securities Exchange Act 
of 1934 for forward-looking statements.  In order to comply with the terms of 
the safe harbor, the Company notes that a variety of factors could cause the 
Company's actual results and experience to differ materially from the 
anticipated results or other expectations expressed in the Company's forward-
looking statements.  The risks and uncertainties that may affect the 
operations, performance, development and results of the Company's business 
include the following: changes in property and casualty reserves; catastrophe 
losses; premium and investment growth; product pricing environment; 
availability of credit; changes in government regulation; performance of 
financial markets; fluctuations in interest rates; availability and pricing of 
reinsurance; litigation and administrative proceedings and general economic 
and market conditions.
