                      OHIO CASUALTY CORPORATION ANNOUNCES
                 RESULTS OF PROCESS RE-ENGINEERING INITIATIVE


FAIRFIELD, Ohio, February 11, 2004  --- Ohio Casualty Corporation (Nasdaq:
OCAS) today announced the results of the first phase of an intense company-
wide process re-engineering initiative, which is a key aspect of the
long-term cost structure efficiency effort to reduce expenses that the
company has undertaken.

The initiative has resulted in an initial reduction of approximately 260 staff
and managerial positions in its eight major field Claims and Commercial Lines
underwriting operations around the country, as well as at its Home Office
location in Fairfield, Ohio. An additional 150-250 positions are expected to
be reduced company-wide before the end of 2nd quarter 2004 as other areas of
the company complete their review of processes and implement improvements. "We
sincerely regret the impact of these reductions on employees and would have
preferred to adjust staffing through normal attrition," said President and
Chief Executive Officer Dan R. Carmichael, CPCU.

Other aspects of the initiative:

  - The process re-engineering initiative represents actions taken to
    improve productivity and customer service.

  - These initial reductions are the result of continued advances in
    technology, productivity efficiencies achieved through process
    improvements, and shifts in business needs.




      -- Specifically, the Commercial Lines Division has leveraged
      technological advances to enhance its abilities to centralize some
      backroom processing transactions for Commercial Lines underwriting.
      Commercial Lines processing will be transferred from one branch
      location to other offices; similar actions had been taken in two
      other branch locations this past year. Process improvements have
      been implemented in its remaining field offices, resulting in staff
      reductions in all these locations.

      -- In the Claims Department, the reductions are primarily in response
      to a continued decrease in the number of claims handled, as well as
      process improvements. In February of 2003, the department began the
      process by reducing claims staff based on a declining claims count,
      which has continued.

"We are systematically streamlining workflows in every functional area, which
improves productivity while maintaining or enhancing the quality of service to
agents and policyholders," said Mr. Carmichael.  "While we are reducing the
size of many field offices, we are maintaining a strong underwriting,
marketing ,and claims presence in all locations that currently provide
services to agents and policyholders.  We began the streamlining process in
our Commercial Lines and Claims field operations. The process improvement
initiative is continuing in all functional areas, with estimated further
reductions based on our re-engineering experience thus far."

Outside the process re-engineering effort, the company has made progress the
past two years in improving its cost structure and reducing expenses. In
addition to the Commercial Lines underwriting and Claims Department actions
outlined above, the Company has:
  - addressed its loss adjustment expenses by reducing claims litigation
    costs;
  - reduced expenses through the centralization of its Personal Lines
    Division;
  - improved procurement practices, including a reduction in
    telecommunications expenses;
  - leveraged emerging technology to streamline, simplify and speed up
    processes; and
  - steadily reduced its employee count and personnel-related expenses.

Today's announced reduction of approximately 260 positions will result in a
net savings of approximately $5.5 million in 2004, which includes a 1st quarter
2004 charge of approximately $4.6 million for severance pay and other related
expenses.  This reduction is expected to result in approximately $14.9 million
in annual savings beginning in 2005, with approximately 60% of the savings
reflected in the underwriting expense ratio and approximately 40% reflected in
the loss adjustment expense ratio.

Added Mr. Carmichael: "We needed to take assertive actions to arrive at proper
staffing levels to provide improved customer service and achieve expense
objectives. We are determined to achieve our expense reduction goals to make
us more competitive, increase the company's financial strength in the market,
enhance the ability to profitably grow our business, continue to deliver
quality services to customers and provide value to shareholders."
