            OHIO CASUALTY CORPORATION REPORTS FINANCIAL RESULTS
                   FOR FOURTH QUARTER AND FULL YEAR 2006


FAIRFIELD, OHIO, February 7, 2007  --- Ohio Casualty Corporation
(NASDAQ:OCAS) today announced the following results for its fourth quarter
ended December 31, 2006, compared with the same period of the prior year:

  -  Net income of $75.5 million, or $1.22 per diluted share, versus $77.3
     million, or $1.19 per diluted share;

  -  All Lines combined ratio (GAAP) of 86.9% versus 86.1%; and

  -  Operating income (A) of $67.3 million ($1.08 per diluted share) versus
     $67.5 million ($1.04 per diluted share).

Results for the full year ended 2006 compared to the same period of 2005:

  -  Net income of $218.3 million, or $3.44 per diluted share, versus
     $212.7 million, or $3.19 per diluted share;

  -  All Lines combined ratio (GAAP) of 93.7% versus 94.2%;

  -  Operating income (A) of $190.0 million ($3.00 per diluted share)
     versus $171.1 million ($2.57 per diluted share); and

  -  Increase in book value per share of $3.25 or 14.4%.





President and Chief Executive Officer Dan Carmichael commented, "Our
results for the fourth quarter and full year 2006 were excellent even when
compared with the outstanding performance of last year.  Once again we've
demonstrated that with discipline and focus, we can achieve profitable
underwriting results and shareholder returns consistent with the targets we
set, even in a highly competitive market.  All three business segments
generated an underwriting profit for 2006.  That strong operating
performance, plus our capital management initiatives, contributed to our
20% operating return on equity for the fourth quarter, and a 14.4% increase
in book value per share for the full year.

"While we had modest new business growth in both Commercial and Personal
Lines last year, long-term, strong premium growth requires an even tighter
bond between our Company and our independent agents.  Accordingly, and
consistent with our recently updated strategic plan, we are working to
equip our agents with more efficient online tools, enhanced product
offerings and new agent-centric services that will help them grow their
businesses and build their position with Ohio Casualty.  The investments
we're making in our strategic initiatives, our continued focus on
profitable underwriting, combined with our strong balance sheet, will make
us an even more attractive agency partner while we maintain our equally
strong commitment to increasing shareholder value."

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

All Lines net premiums written decreased 3.3% during the fourth quarter
over the same period last year primarily as a result of lower in force
policy counts in the Personal Lines segment and the commercial umbrella
product line, rate reductions taken in the Personal Lines segment and lower
Commercial Lines assumed premiums from mandatory workers' compensation and
commercial auto pools.  Specialty Lines net premiums written increased
slightly during the quarter, a result of growth in the fidelity/surety
product line.  For the full year, new business premium production was up
9.3% and 7.4% in Commercial and Personal Lines, respectively, while policy
retention was up for those two operating segments as well as for the
commercial umbrella product line.  This growth was offset by rate
reductions and lower assumed premiums from mandatory workers' compensation
and commercial auto pools.

The All Lines combined ratio for the current year fourth quarter was very
strong and was up just slightly when compared with the same period of the
prior year.  This is the result of a 3.4 point increase in the loss and
loss adjustment expense (LAE) ratio, partially offset by a 2.6 point
improvement in the underwriting expense ratio.  The increase in the loss
and LAE ratio is principally the result of increased catastrophe losses,
loss cost trends increasing at a rate faster than premium rate increases
and favorable reserve development that was lower in the current quarter
when compared to the same period of 2005.  The improvement in the
underwriting expense ratio is primarily the result of recognition of state
premium tax refunds related to prior years in the amount of $9.2 million
partially offset by an increase in a provision for legal expenses.

Favorable prior year loss and LAE reserve development was $14.8 million
(4.2 points) and $16.5 (4.5 points) million in fourth quarter 2006 and
2005, respectively.  The fourth quarter 2006 reserve development was
favorable for most product lines during the quarter with a few exceptions,
most notably workers' compensation, which experienced adverse development.
For the full year 2006, favorable reserve development was $52.2 million
(3.7 points) compared with $20.1 million (1.4 points) in 2005.  This year-
over-year increase in favorable development is primarily the result of
increased favorable development in the commercial umbrella product line and
approximately $20 million less adverse development for workers'
compensation.

For the current year fourth quarter, catastrophe losses increased the
combined ratio by $5.8 million (1.6 points) compared with a favorable
impact of ($0.3) million (0.1 point) in the same period last year.  For the
year, catastrophe losses were $32.8 million (2.3 points) compared with
$25.8 million (1.8 points) of the prior year.

Other Highlights
Consolidated pre-tax investment income for the quarter increased $1.6
million compared with the prior year.  This increase is primarily related
to $3.2 million of interest income on state premium tax refunds related to
prior years, which were finalized during the quarter, partially offset by
an increased allocation to lower-yielding tax-exempt securities, which now
comprise 37.3% of fixed-income securities at December 31, 2006 compared
with 33.7% in the prior year.  For the year, investment income increased
$7.3 million over the prior year.  In addition to the above, 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 2006 and 2005, the Corporation repurchased 3,463,396 and 1,516,105
shares of common stock at an average cost of $28.95 and $26.04,
respectively, under share repurchase programs authorized by the Board of
Directors.  As of December 31, 2006, the Corporation has $72.0 million of
share repurchase authority remaining.

(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:

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:
