		OHIO CASUALTY GROUP MEMBER COMPANY TRANSFERS
		--------------------------------------------
	    OBLIGATIONS TO RENEW PRIVATE PASSENGER AUTO BUSINESS
	    ----------------------------------------------------
				IN NEW JERSEY
				-------------

FAIRFIELD, Ohio, December 19, 2001 - Ohio Casualty Corporation (Nasdaq: OCAS)
(the Corporation) today announced that Ohio Casualty of New Jersey, Inc. (OCNJ)
has transferred its obligations to renew 100% of OCNJ's private passenger
automobile business written in the state of New Jersey to Proformance Insurance
Company (Proformance), Freehold, New Jersey.  Ohio Casualty Corporation is the
holding company of The Ohio Casualty Insurance Company (the Company).  The
Company, together with Ohio Casualty of New Jersey, Inc. and four other
property-casualty subsidiary companies, make up Ohio Casualty Group.  National
Atlantic Holdings Corporation is the parent of Proformance Insurance Company.
Merrill Lynch & Co. advised the Corporation on the transaction and issued a
fairness opinion.

President and CEO Dan Carmichael, CPCU, commented "This transaction to
effectively exit New Jersey private passenger auto business eliminates a major
risk to the successful execution of our Corporate Strategic Plan.  Since the
Plan was announced in June, the environment in New Jersey private passenger
auto business has become more unstable for the Corporation due to the inability
to control the volume of writings and profitability of this line of business in
the state.  Writing profitable business in the New Jersey private passenger
auto market is not one of our core competencies.  Although there is a
significant cost in exiting this market, the New Jersey transaction allows us
to focus on our core competencies and to grow our other lines of business in
New Jersey.  It is expected to also lead to improved operating performance in
2002 and beyond.  The transaction we are announcing today concludes a
significant effort to evaluate alternatives to reduce or eliminate the risk of
our continued participation in the New





Jersey private passenger auto market.  We firmly believe this transaction is
our best course of action."

Under the terms of this transaction, OCNJ will pay Proformance $40.6 million to
assume its obligations of renewal for the New Jersey private passenger auto
policies.  OCNJ will also have a contingent liability of up to $15.6 million
(supported by a guarantee from the Company) to be paid to Proformance to
maintain a premiums-to-surplus ratio of 2.5 to 1 on the transferred business if
the premiums-to-surplus ratio increases above 2.5 to 1 during the next 3 years.
OCNJ will cease writing private passenger auto business in New Jersey, but OCNJ
will be retained by the Company as a subsidiary.  In addition, the Company or
one of its subsidiary companies will purchase, for $500,000, a 19.99 percent
non-voting equity stake in Proformance's parent, National Atlantic Holdings
Corporation.  The Ohio Casualty Group will maintain all of its other lines of
business in New Jersey, including homeowners, standard commercial lines, and
specialty commercial lines.

Elizabeth Riczko, FCAS, MAAA, CPCU, Executive Vice President and COO for
Personal Lines, commented "The New Jersey private passenger auto business has
been losing money and draining valuable resources and was projected to continue
to do so in the future as long as needed price increases were not achieved.  We
expect the elimination of New Jersey private passenger auto business to
positively impact the before-tax underwriting results by approximately $14
million and $19 million in 2002 and 2003, respectively, and to a similar degree
for several years thereafter."

The projected impact of the New Jersey transaction on the Corporation for the
years 2001 through 2003 is summarized on the following table.

Projected impact of the New Jersey transaction versus continuing to write New
Jersey private passenger auto business ($ in millions):

				    2001          2002            2003

     (1)Underwriting expenses assumes contingent liability is zero

The initial payment of $40.6 million for the transfer of the renewal obligation
for the New Jersey private passenger auto business, to be paid in twelve
installments concurrent with non-renewal of policies by OCNJ, will be accrued
in the fourth quarter of 2001.  This will reduce after-tax operating income by
approximately $26 million in the fourth quarter of 2001.  Statutory surplus is
also reduced by approximately $26 million subject to deferred tax asset
admissibility limits that could temporarily reduce statutory surplus to a
larger degree until actual payments are made.  The reduction in statutory
surplus is not expected to cause any violation of the Corporation's debt
covenants.





On or about March 31, 2002, OCNJ will begin sending required notices of non-
renewal to its existing policyholders, along with notices that offer a
guaranteed option to renew their policies with Proformance.  Proformance also
will appoint approximately 200 of OCNJ's agencies.

As of September 30, 2001, OCNJ had approximately 66,000 personal auto policies
in force in New Jersey, with approximately $91 million in net premiums written
year-to-date as of September 30, 2001.  All other lines of business in the
state, which are expected to remain near current levels, total approximately
$105 million in net premiums written year-to-date as of September 30, 2001.

Of the approximately 314 claims and underwriting operations employees in New
Jersey, approximately 117 will be impacted by this transaction in the months
ahead as business is transitioned to Proformance.  These employees will be
transferred to Proformance and there will be no severance related expenses for
Ohio Casualty Group.  The employees impacted are located primarily in OCNJ's
regional office in Voorhees, New Jersey, and in the New Jersey regional claims
office, Mt. Laurel, New Jersey.


Impact on Statutory Property & Casualty Projected Results for Years 2001-2003
In June 2001 the Corporation announced a new Corporate Strategic Plan that
included combined ratio projections for years 2001 through 2003.  Through the
third quarter of 2001 the financial performance of the Corporation was on track
to successfully achieve the first fiscal year financial results of the
Corporate Strategic Plan.  The elimination of the New Jersey private passenger
auto business is expected to increase the underwriting expense ratio while
lowering the loss and loss adjustment expense ratio by a greater degree over a
period of time.

The Corporation is in the process of reviewing its reinsurance contracts for
2002 and updating its Corporate Strategic Plan.  The recent terrorist attacks
are expected to increase reinsurance premium rates while also improving the
pricing environment for new and renewal direct business.  The net impact on
premiums cannot yet be determined.  In early 2002, the Corporation plans to
revise the 2002 and 2003 forecasted financial results that were reflected in
the Corporate Strategic Plan projections as of June 2001.
