                     OHIO CASUALTY CORPORATION REPORTS
                    FINANCIAL RESULTS FOR THIRD QUARTER


FAIRFIELD, OHIO, November 1, 2006  --- Ohio Casualty Corporation
(NASDAQ:OCAS) today announced the following results for its third quarter
ended September 30, 2006, compared with the same period of the prior year:

  -  Net income of $55.3 million, or $0.89 per diluted share, versus $55.5
     million, or $0.85 per diluted share;
  -  All Lines combined ratio (GAAP) of 93.9% versus 99.5%; and
  -  Operating income (A) of $47.8 million ($0.77 per diluted share) versus
     $32.7 million ($0.50 per diluted share).

Results for the nine months ended September 30, 2006, compared with the
same period of the prior year:

  -  Net income of $142.8 million, or $2.24 per diluted share, versus
     $135.4 million, or $2.02 per diluted share;
  -  All Lines combined ratio (GAAP) of 96.1% versus 96.9%; and
  -  Operating income (A) of $122.7 million ($1.92 per diluted share)
     versus $103.6 million ($1.55 per diluted share).

President and Chief Executive Officer Dan Carmichael commented, "We are
pleased to deliver strong operating results across all segments for the
third quarter through a combination of disciplined underwriting, lower
catastrophe losses, efficiency gains and the benefit of favorable loss
frequency and




prior accident year development trends.  While we remain focused on
profitable, disciplined underwriting, good opportunities for growth are
harder to find in the increasingly competitive market, however, I am
encouraged by the acceptance of our new technology applications and the
increase in production of new business by our agents.

Last quarter's results support our positive outlook for our future,
including our ability to maintain solid underwriting results in a softening
market and creating more value for our shareholders.  Rating agencies have
expressed similar confidence in our company through their actions during
the quarter.  With Standard & Poor's upgrading its rating of us, now all
four of the rating agencies that assess our financial strength have
assigned investment grade ratings with Fitch subsequently upgrading their
existing investment grade rating by one notch.  Finally, the Board's
decision in September to approve a second, $100 million share repurchase
program reaffirms our commitment to maximize shareholder value as our
overall financial strength continues to grow."

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

Net premiums written decreased 2.6% over the same quarter last year primarily
as a result of lower in-force policy counts and rate reductions in Personal
Lines.  These decreases were partially offset by increased new business
premium production in Personal and Commercial Lines, which is a positive
reflection of the new marketing, sales and product initiatives launched this
year to profitably grow the business.

Results for the third quarter included $13.7 million of favorable
development in loss and loss adjustment expense reserves for prior accident
years, compared with unfavorable development of $3.1 million in the third
quarter of 2005.  Reserve development was favorable for most product lines
during the third quarter 2006 with the exception of a couple product lines,
most notably workers' compensation, which experienced adverse development.




Consolidated pre-tax net investment income for the quarter remained
relatively flat compared with the prior year.  However, after giving
consideration in both three and nine month periods ending September 30,
2005 of the $2.5 million of interest income related to federal income tax
settlements with the Internal Revenue Service which was finalized during
the third quarter of 2005, investment income increased 4.9% and 5.6%,
respectively.  The increase in investment income is a result of reduced
investment related expenses, positive operating cash flows and an
improvement in reinvestment yields resulting from the upward movement in
interest rates compared with the prior year.

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 $1.60, or 7.1% to $24.14 at September 30,
2006, compared to $22.54 at December 31, 2005.

During the third quarter of 2006, the Corporation repurchased 249,186
shares of its common stock at an average cost of $25.87.  These repurchases
complete the previous share repurchase program which was authorized by the
Corporation's Board of Directors in the third quarter of 2005.  Under this
program, four million shares were repurchased at an average cost of $27.94.
On September 28, 2006, the Board of Directors authorized another share
repurchase program with the ability to repurchase up to $100 million of the
Corporation's common stock.  Purchases may be made in the open market or in
privately negotiated transactions.  As of October 31, 2006, the Corporation
has repurchased 227,200 shares under the new share repurchase program at
an average cost of $27.19.

On July 26, 2006, Standard and Poor's (S&P) announced that it had upgraded
the senior unsecured debt rating of the Corporation to BBB- and the
insurance financial strength rating of its operating subsidiaries to A-.
In this same action, S&P changed the outlook on ratings to stable.  In
addition, during the third quarter, Fitch, Inc. (Fitch) announced that it
has upgraded our financial strength rating to A from A- and upgraded the
Corporation's issuer default rating to BBB+ from BBB.  At the same time,
Fitch upgraded the outstanding debt rating to BBB from BBB- and changed the
outlook from positive to stable.

of operations at September 30, 2006, please see the Quarterly Report on
Form 10-Q for this period, filed with the Securities and Exchange
Commission (SEC).

(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.

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:
