For Immediate Release


                         OHIO CASUALTY CORPORATION
                       ANNOUNCES STORM LOSS ESTIMATE


FAIRFIELD, Ohio, May 14, 2003  --- Ohio Casualty Corporation (Nasdaq:OCAS)
today announced that second quarter earnings will be impacted by net
catastrophe losses estimated at $12 million before tax which were incurred
during the period April 1 though May 11, 2003.  Approximately $9 million of
the estimated catastrophe losses are related to severe weather in seventeen
states from May 2 through 11, 2003.  The impact of the estimated $12 million
in catastrophe losses is expected to be approximately 3.5 points on the full
second quarter 2003 combined ratio.  Catastrophe losses of $10.3 million
impacted the second quarter 2002 combined ratio by 2.8 points and the 1995-
2001 second quarter historical average was 5.4 points.

The Corporation typically does not announce catastrophe estimates prior to
reporting complete results for the quarter.  However, disclosure is being made
at this time due to the high level of publicity surrounding the recent storms
and due to the Corporation's relatively high concentration of business in
several of the states impacted.

President and Chief Executive Officer Dan Carmichael, CPCU commented, "We have
teams of additional claims professionals in place in several areas that
suffered significant storm damage as we continue to deliver excellence in
claims service to our policyholders."
