Note 1 - During 1996, the Corporation entered into an interest rate swap.  The 
effect of the swap agreement is to establish a hedge against future interest 
rate swings on its variable rate term loan.  Net proceeds or payments from the 
swap are charged to interest expense in the current period.

Covered call options are written on stocks and bonds held in the investment 
portfolio. Changes in the values of the covered call options are recognized 
in shareholders' equity as unrealized appreciation or depreciation.

Note 2 - 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.

ITEM 2.   Management's  Discussion  and  Analysis  of  Financial  Condition  
          and Results of Operations

Property and casualty pre-tax underwriting losses for the nine months ended 
September 30, 1997 were $55.4 million, $1.61 per share, compared with $121.6 
million, $3.45 per share for the same period in 1996.  Gross premiums for the 
first nine months of 1997 decreased .4% over the same period in 1996.  
Commercial lines decreased 1.7% and personal lines increased .7% for the first 
nine months of 1997.  Property and casualty net premiums decreased 1.3% for 
the third quarter of 1997 over the same period a year ago.

Premium writings continue to demonstrate the impact of our agency 
repositioning strategy of last year.  Premium from active agents increased 
5.1% year-to-date over 1996.  New Jersey is our largest state with 18.2% of 
total premiums written during the year.  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).  The assessment for 1997 is 
approximately $4.2 million compared with $4.4 million in 1996.  On August 11 
the governor of New Jersey, Christie Whitman, called for guaranteed rate 
reductions on personal auto insurance of up to 25%.  Her proposals are 
currently pending in the New Jersey Legislature and it is uncertain what 
impact, if any, they will have on the Corporation.  Through September of 1997, 
New Jersey private passenger auto premium totaled $83.7 million which is 9.1% 
of total premium and 23.9% of total private passenger auto premium for the 
Corporation.

As part of its reinsurance transactions, the Corporation participates in an 
experience rated First Casualty Excess of Loss Treaty.  In accordance with 
FASB 113 (Accounting and Reporting for Reinsurance of Short-Duration and Long-
Duration Contracts), anticipated profits from this agreement are recorded as 
returned premium.  Through September 30, 1997, due to unanticipated favorable 
development in our liability lines, the actuarial projections of the estimated 
profit from this agreement were updated to $10.3 million.  Of this amount, 
$7.3 million was recognized as return premium in the second quarter with $3.0 
million recognized as return premium in the first quarter.

The combined ratio for the first nine months decreased 7.1 points to 106.1% 
from 113.2% over the same period last year.  The nine-month combined ratio for 
homeowners decreased 31.2 points to 117.1% from 148.3% in the same period last 
year.  Personal automobile, the Corporation's largest line, recorded a 1997 
nine-month combined ratio of 104.0%, down 9.0 points from 113.0% in 1996.  
During the first nine months of 1996, results for both homeowners and personal 
automobile were negatively impacted by a series of severe winter storms that 
occurred throughout the Midwest.  Workers' compensation combined ratio for the 
first nine months of 1997 decreased 5.5 points to 92.7% from 98.2% during the 
same period last year.  

The general liability combined ratio for the third quarter increased 27.3 
points to 111.5% from 84.2% in 1996.  The nine-month combined ratio increased 
11.3 points to 104.1% from 92.8% in the same period of 1996.  These increases 
are due primarily to increased severity in that line.  At present the 
Corporation believes this to be an aberration rather than a trend.  The nine-
month combined ratio for CMP, fire and inland marine decreased 5.7 points to 
108.8% from 114.5% in 1996 due primarily to reduced weather related losses.

Third quarter catastrophe losses were $9.0 million and accounted for 3.0 
points on the combined ratio.  This compares with $16.5 million and 5.5 points 
for the same period in 1996.  Year to date catastrophe losses decreased $34.7 
million from $53.5 million in 1996 to $18.8 million in 1997.  While 
catastrophe losses for the period were considerably lower than in 1996, an 
increase in severity in general liability and workers' compensation led to the 
increased combined ratio for the quarter.

In 1996, the Corporation analyzed incurred but not reported reserves for 
general liability and commercial multiple peril to segregate between asbestos 
and environmental losses and all other losses.  As a result of this analysis, 
$27.4 million in incurred but not reported reserves were segregated as 
asbestos and environmental related.  This brought total asbestos and 
environmental reserves to their current level of $41.0 million.

                                        7

For the quarter, property and casualty before tax investment income was $44.1 
million, $1.30 per share, decreasing slightly from $44.9 million, $1.29 per 
share, for the same period last year.  The effective tax rate on investment 
income for the third quarter of 1997 was 25.6% compared with 23.7% for the 
comparable period in 1996.  Additional discussion of the Corporation's 
investment tax planning strategy is included in the 1996 Annual Report to 
Shareholders.

Net cash generated by operations was $.3 million for the first nine months of 
the year compared with net cash used of $16.9 million for the same period in 
1996.  Shareholder dividend payments were $43.3 million in the first nine 
months of 1997 compared with $42.3 million for the same period of 1996.

During the first nine months of 1997, Ohio Casualty continued its share 
repurchase program.  The total number of shares acquired during the period was 
1,217,888, or 3.6% of outstanding shares, at an average price of $41.20 per 
share for a total cash outflow of $50.2 million.  The Company has remaining 
authorization to repurchase 853,612 additional shares.

In 1995, the Corporation reinsured substantially all of its life insurance and 
related businesses to Great Southern Life Insurance Company.  Great Southern 
is expected to replace Ohio Life as the primary carrier through an assumption 
and novation sometime during the fourth quarter.  The ultimate timing of the 
assumption is dependent upon receipt of state approval from each state in 
which the life business is located.  When the assumption occurs, the 
unamortized ceding commission will be recognized in that period's income.  The 
current unamortized balance of the ceding commission is $10.1 million.

Investments in below investment grade securities (Standard and Poor's rating 
below BBB-) had an aggregate carrying value of $141.3 million and an aggregate 
amortized cost of $135.0 million at September 30, 1997.  Unrated securities 
had an aggregate carrying value of $247.2 million and an aggregate amortized 
cost of $230.1 million.  At year-end 1996 the aggregate carrying value of 
below investment grade securities was $184.6 million and the aggregate 
amortized cost was $180.0 million.  At year-end 1996, the aggregate carrying 
value of unrated securities was $315.4 million and the aggregate amortized 
cost was $308.3 million.  Utilizing ratings provided by other agencies such as 
the National Association of Insurance Commissioners, categorizes $18.4 million 
of $247.2 million in unrated securities as non-investment grade.  This brings 
the aggregate market value of non-investment grade securities to $159.7 
million at September 30, 1997, compared with $211.9 million at year-end 1996.

All of the Corporation's below investment grade securities (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 61 
corporate borrowers in approximately 31 industries.

In 1996 the Insurance Services Office (ISO) elected to become a public 
corporation.  As such, each member of ISO was allocated an equity stake in the 
new entity.  Effective January 1, 1997, ISO became a for-profit corporation 
and Ohio Casualty received 138,899 shares valued at $25 per share for a total 
value of $3.5 million.  The receipt of these shares was recorded in the first 
quarter as miscellaneous income and the value of the shares was added to our 
equity portfolio.

For further discussion of the Corporation's investments, see Item 1 of the 
Corporation's Form 10-K for the year ended December 31, 1996.

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 have at least four times the necessary capital 
to conform with the risk-based capital model.

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

On October 27, 1997, the Corporation signed a new credit facility with Chase 
Manhattan Bank (see Exhibit 10c ).  The credit facility makes available a $300 
million revolving line of credit, which will immediately be accessed to 
refinance the existing term loan balance with Chase Manhattan Bank.  The 
interest rate on the line of credit is based upon various bases including the 
London InterBank Offered Rate.  The credit agreement contains financial 
convenants and provisions customary for such arrangements.  Those financial 
covenants include a required minimum level of statutory surplus and a maximum 
debt to equity ratio.  The agreement expires October 27, 2002, with any 
outstanding balance due at that time.

The Corporation has reserved $77.5 million (including interest) for a 
Proposition 103 liability asserted by the California Department of Insurance.  
The Corporation is currently involved in hearings with the State of 
California.  The final arguments concluded in the first quarter of 1997 but 
were recently reopened for additional testimony on loss development.  A ruling 
from the Administrative Law Judge is expected before the end of 1997.  At that 
time, the Insurance Commissioner will have 60 days to take the ruling under 
advisement and return with a final ruling.  The Corporation will continue to 
challenge the validity of any rollback and plans to continue negotiations with 
Department officials.  It is uncertain when this will be resolved.  For 
further discussion of the Corporation's California withdrawal, see footnote 14 
in the Corporation's Annual Report to Shareholders.

The SEC issued Financial Reporting Release 48 (Disclosures about Derivatives 
and Other Financial Instruments) which is effective for periods ending after 
June 15, 1997 for registrants with market capitalizations in excess of $2.5 
billion and effective one year later for all other registrants.  The 
Corporation has a market capitalization of less than $2.5 billion.  FRR 48 
does not impact the Corporation's financial statements but does require 
enhanced disclosures about market risk inherent in derivatives and other 
financial instruments (as defined by FRR 48).  The additional information will 
be included in the footnotes to the Annual Report and annual filings with the 
SEC after June 15, 1998.

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

In February 1997, the FASB issued Statement of Financial Accounting Standards 
No. 129 which clarifies disclosure requirements regarding a company's capital 
structure.  The Corporation is currently assessing the disclosure required 
with SFAS 129 which becomes effective December 31, 1997.

In June 1997, the FASB issued Statement of Financial Accounting Standards No. 
130, Reporting Comprehensive Income.  This standard establishes a requirement 
for display of Comprehensive Income in a set of general-purpose financial 
statements for fiscal periods beginning after December 15, 1997.

In June 1997, the FASB also released Statement of Financial Accounting 
Standards No. 131, Disclosures About Segments of an Enterprise and Related 
Information.  The standard requires reporting certain information about 
operating segments for fiscal periods beginning after December 15, 1997.  The 
Corporation is currently reviewing what changes, if any, this will require in 
the presentation of financial results.
