                     OHIO CASUALTY CORPORATION REPORTS
                   FINANCIAL RESULTS FOR SECOND QUARTER



FAIRFIELD, OHIO, July 30, 2007  --- Ohio Casualty Corporation (NASDAQ:OCAS)
today announced the following results for its second quarter ended June 30,
2007, compared with the same period of the prior year:

  -  Net income of $56.6 million, or $0.92 per diluted share, versus $35.6
     million, or $0.55 per diluted share;

  -  All Lines combined ratio (GAAP) of 91.4% versus 99.2%; and

  -  Operating income (A) of $52.4 million ($0.85 per diluted share) versus
     $32.2 million ($0.50 per diluted share).

Results for the six months ended June 30, 2007, compared with the same
period of the prior year:

  -  Net income of $119.7 million, or $1.95 per diluted share, versus $87.5
     million, or $1.35 per diluted share;

  -  All Lines combined ratio (GAAP) of 90.3% versus 97.0%; and

  -  Operating income (A) of $110.3 million ($1.79 per diluted share)
     versus $74.9 million ($1.16 per diluted share).

President and Chief Executive Officer Dan Carmichael commented, "Our second
quarter operating performance remained strong, improving significantly over
last year, and like the first quarter, all three operating segments
generated an underwriting profit.  Our results reflect our successful
efforts to maintain




underwriting discipline in a very competitive market and we continue to
experience substantial favorable development from prior accident years.
Since introducing our first Strategic Plan in the second quarter of 2001,
progress toward achieving consistent solid underwriting performance,
quality claims handling and superior service to our agents has been steady,
enabling us to produce and maintain strong operating results.

In the recent past, Ohio Casualty Corporation has created value for
shareholders by continually improving financial results and delivering
increasingly competitive shareholder returns.  During the past six years we
restored underwriting profitability, improved our operating efficiency and
technology capabilities, and also significantly strengthened our capital
position while earning rating upgrades from all major rating agencies.

I deeply appreciate the significant effort and professionalism of our
agents and employees in accomplishing these achievements.  We will continue
to deliver on our promise to policyholders and commitment to independent
agents as we transition to new ownership upon the completion of our pending
acquisition by Liberty Mutual Group."

All Lines net premiums written declined for the three and six month periods
ended June 30, 2007, when compared with the same periods of the prior year,
due primarily to a decline in new business premium production across all
three business segments, a decline in premium rates for both Personal and
Commercial Lines, lower Commercial Lines assumed premiums from mandatory
workers' compensation and commercial auto pools as well as lower in-force
policy counts in the Personal Lines segment and commercial umbrella/other
product line.  Net premiums written were also reduced by a $7.0 increase in
ceded premium on experience based reinsurance contracts during the second
quarter of 2007.  The experience rated reinsurance contracts are for a
funded layer of casualty excess of loss reinsurance coverage.  These
declines were partially offset by continued growth in the fidelity and
surety bond product line.

The improvement in the All Lines combined ratio for the second quarter was
primarily the result of a significant increase in favorable prior year loss
and loss adjustment expense reserve development and a reduction in
catastrophe losses.  These improvements were partially offset by increasing
loss cost trends and declining premium rates, as well as an increase in the
underwriting expense ratio.  The increase in the underwriting expense ratio
is a result of increased incentive compensation and commissions related to
our improved profitability, as well as the impact of lower premium, as
described above.  The above ratios, for both three and six month periods
ended June 30, 2007, were also negatively impacted by the $7.0 increase in
ceded premium on experienced based reinsurance contracts recorded during
the second quarter of 2007.  The impact on the combined ratio of this
increase in ceded premium was 1.9 points and 0.9 points for the three and
six month periods, respectively.

Favorable prior year loss and LAE reserve development was $41.4 million
(12.2 points) and $10.8 million (3.0 points) in the second quarter 2007 and
2006, respectively.  Reserve development was favorable for almost all
product lines during the second quarter 2007 and is primarily attributable
to actual severity being lower than expected, much of which is occurring in
the casualty lines, a result of our more disciplined underwriting and
improved claims handling practices which commenced in the 2000-2001
timeframe.

Book value per share increased $1.21 or 4.7% to $27.00 at June 30, 2007,

(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:
