For Immediate Release


                       OHIO CASUALTY CORPORATION REPORTS
                      FINANCIAL RESULTS FOR THIRD QUARTER


FAIRFIELD, OHIO, October 25, 2005  --- Ohio Casualty Corporation
(NASDAQ:OCAS) today announced the following results for its third quarter
ended September 30, 2005, compared with the same period of the prior year:

   - Net income of $55.5 million, or $0.85 per diluted share, versus $19.6
     million, or $0.30 per diluted share;
   - All Lines combined ratio (GAAP) of 99.5%, a 0.8 point improvement; and
   - Operating income (A) of $32.7 million versus $22.4 million, a $10.3
     million or 46.0% increase.

Results for the nine months ended September 30, 2005, compared with the
same period of the prior year:

   - Net income of $135.4 million, or $2.02 per diluted share, versus $71.5
     million, or $1.07 per diluted share;
   - All Lines combined ratio (GAAP) of 96.9%, a 4.2 point improvement; and
   - Operating income (A) of $103.6 million versus $71.4 million, a $32.2
     million or 45.1% increase.

President and Chief Executive Officer Dan Carmichael commented, "It's
remarkable that in a quarter in which our country experienced the worst
ever natural catastrophe our agents and staff produced another positive
underwriting result; it was the twelfth quarter in a row of operating
profitability.   I'm also pleased that we were able to promptly serve our
policyholders and independent agents who were affected by the Gulf Coast
storms.  As we previously announced, our net catastrophe losses for the
current quarter




were approximately $11.6 million on an after tax basis, with approximately
$9.8 million related to damage incurred from Hurricane Rita and $1.4 million
from Hurricane Katrina.  The total catastrophe loss impact added 4.9 points
to the combined ratio for the current quarter. When these catastrophe results
are viewed relative to the industry results for these same storms, it is
evidence that our disciplined underwriting and risk management approach is
clearly paying off in enhanced profitability. We will continue to focus on
improving our already strong profitability through our pricing strategies,
our disciplined underwriting standards, and a continuing effort to manage
expenses."

The major components of net income are summarized in the table below:

Results for the third quarter included $3.1 million of unfavorable
development in loss and loss adjustment expense reserves for prior accident
years, compared with favorable development of $3.1 million in the third
quarter of 2004.

In connection with the adoption of Emerging Issues Task Force ("EITF")
Consensus 04-8 "The Effect of Contingently Convertible Debt on Diluted
Earnings per Share" in the fourth quarter 2004, average shares outstanding-
diluted and net income per share-diluted were restated for the three and
nine months ended September 30, 2004.  The restatement lowered net income
per share-diluted by $0.01 and $0.07, respectively, for the three and nine
months ended September 30, 2004.

Consolidated before-tax net investment income increased $6.5 million in the
quarter as a result of continued growth in our investment portfolio, as the
insurance operations continue to generate positive cash flows.  In
addition, we recognized $2.5 million of interest income related to federal
income tax settlements with the Internal Revenue Service, which were
finalized in the third quarter of 2005. These increases were somewhat
offset by lower before-tax investment yields in 2005 and our strategy to
invest more in tax-exempt securities. On an after-tax basis, investment
income increased $5.1 million in the quarter, which further reflects the
benefits of our investment in tax-exempt securities.





During the third quarter of 2005, settlements with the Internal Revenue
Service for tax years 1996 through 2001 were favorably concluded.  The
result of these settlements was an increase to net income for the quarter
and nine months ended September 30, 2005 of $16.8 million ($0.26 per share
for the quarter and $0.25 per share for the nine-months).  The effect on
operating income, which excludes that portion of the settlement applicable
to taxes on realized capital gains and losses, was an increase of $6.1
million, or $0.09 per share for both the third quarter and nine months
ended September 30, 2005.  The above-referenced items had the effect of
lowering the overall effective income tax rate for the nine months ended
September 30, 2005 by 6.6 points.

Book value per share increased $0.93, or 4.5% to $21.75 at September 30,
2005, compared to $20.82 at December 31, 2004.

On August 18, 2005, the Board of Directors approved a share repuchase
program of up to four million shares of the Corporation's common stock.
During the third quarter, the Corporation has repurchased 570,115 shares
at an average cost of $25.61.  For the period October 1, 2005 through
October 24, 2005, the Corporation has repurchased an additional 618,270
shares of its common stock at an average price per share of $25.95. Total
authorized shares remaining under the program are 2,811,615.

(A) Reconciliation of Non-GAAP Financial Measures to GAAP Financial
Measures

Reconciliation of Net Income to Operating Income
Management of the Consolidated Corporation believes the significant
volatility of realized investment gains and losses limits the usefulness of
net income as a measure of current operating performance.  Accordingly,
management uses the non-GAAP financial measure of operating income to
further evaluate current operating performance.  Operating income, both in
dollar amounts and per share amounts, are reconciled to net income and net
income per share in the table below:

As noted above, results for the third quarter and nine months ended
September 30, 2005, include the effect of settlements with the Internal
Revenue Service related to tax years 1996 through 2001. The settlements
increased net income by $16.8 million ($0.26 per share for the third
quarter, $0.25 per share for the nine months), and operating income by $6.1
million, or $0.09 per share for quarter and nine months.

Also, as mentioned previously, in connection with the adoption of EITF 04-8
in the fourth quarter 2004, the Consolidated Corporation was required to
restate per-share amounts for the three months and nine months ended
September 30, 2004.  The restatement lowered net income per share-diluted,
by $0.01 and $0.07 for the three and nine months ended September 30, 2004,
respectively.




Reconciliation of Net Income Return on Equity to Operating Income Return
on Equity
Operating income return on equity is a ratio management calculates using
non-GAAP financial measures.  It is calculated by dividing the annualized
consolidated operating income (see calculation below) for the most recent
quarter by the adjusted average shareholders' equity for the quarter using
a simple average of beginning and ending balances for the quarter,
excluding from equity after-tax unrealized investment gains and losses.
This ratio provides management with an additional measure to evaluate the
results excluding the unrealized changes in the valuation of the investment
portfolio that can fluctuate between periods.  The following table
reconciles operating income return on equity to net income return on
equity, the most directly comparable GAAP measure:
