                     OHIO CASUALTY CORPORATION REPORTS
                   FINANCIAL RESULTS FOR SECOND QUARTER


FAIRFIELD, OHIO, July 26, 2006  --- Ohio Casualty Corporation (NASDAQ:OCAS)
today announced the following results for its second quarter ended June 30,
2006, compared with the same period of the prior year:

  -  Net income of $35.6 million, or $0.55 per diluted share, versus $42.1
     million, or $0.63 per diluted share;
  -  All Lines combined ratio (GAAP) of 99.2% versus 95.5%; and
  -  Operating income (A) of $32.2 million versus $33.2 million.

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

  -  Net income of $87.5 million, or $1.35 per diluted share, versus $79.8
     million, or $1.18 per diluted share;
  -  All Lines combined ratio (GAAP) of 97.0% versus 95.5%; and
  -  Operating income (A) of $74.9 million versus $70.9 million.

President and Chief Executive Officer Dan Carmichael commented, "Our second
quarter operating results reflected both a highly competitive marketplace,
a higher, more normal pattern of catastrophe losses and our determination
not to compromise our underwriting standards to chase marginal
opportunities.  Our two primary challenges continue to be the monitoring
and controlling of expenses and finding more opportunities to grow with
adequately priced business.  We remain confident that our strategy will
continue to optimize results and produce superior benefits for
policyholders, independent agents and our shareholders."

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

Results for the second quarter included $10.8 million of favorable
development in loss and loss adjustment expense reserves for prior accident
years, compared with favorable development of $2.9 million in the second
quarter of 2005.  Reserve development was favorable for most product lines
during the second quarter 2006 with the exception of a couple product lines
which experienced adverse development.

Consolidated pre-tax net investment income increased $3.3 million in the
quarter as a result of a modest improvement in reinvestment yields
resulting from the upward movement in interest rates and positive operating
cash flows.

Book value per share decreased $0.15, or 0.7% to $22.39 at June 30, 2006,
compared to $22.54 at December 31, 2005.

During the second quarter, the Corporation repurchased 2,197,929 shares of
its common stock at an average cost of $29.48 per share, which brings the
total shares repurchased under the program to 3,750,814 at an average cost
of $28.08.  Total authorized shares remaining under the program at June 30,
2006 is 249,186.

In addition, Moody's Investors Service announced that it has affirmed the
Baa3 senior debt rating of Ohio Casualty Corporation and the A3 insurance

(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:
