Item 6.	Indemnification of Directors and Officers.

	Division (E) of Section 1701.13 of the Ohio Revised Code and Article V
of the Code of Regulations of Ohio Casualty Corporation (the "Company") relate
to indemnification of the Company's directors and officers against liabilities
arising in connection with the performance of their respective duties.

	Division (E) of Section 1701.13 of the Ohio Revised Code provides as
follows:

	(E) (1)  A corporation may indemnify or agree to indemnify any person
who was or is a party, or is threatened to be made a party, to any pending, or
completed action, suit, or proceeding, whether civil, criminal, administrative,
or investigative, other than an action by or in the right of the corporation,
by reason of the fact that he is or was a director, officer, employee, or
agent of the corporation, or is or was serving at the request of the
corporation as a director, trustee, officer, employee, member, manager, or
agent of another corporation, domestic or foreign, nonprofit or for profit, a
limited liability company, or a partnership, joint venture, trust, or other
enterprise, against expenses, including attorney's fees, judgments, fines and
amounts paid in settlement actually and reasonably incurred by him in
connection with such action, suit, or proceeding, if he acted in good faith
and in a manner he reasonably believed to be in or not opposed to the best
interests of the corporation, and, with respect to any criminal action or
proceeding, if he had no reasonable cause to believe his conduct was unlawful.
The termination of any action, suit, or proceeding by judgment, order,
settlement, or conviction, or upon a plea of nolo contendere or its equivalent,
shall not, of itself, create a presumption that the person did not act in good
faith and in a manner he reasonably believed to be in or not opposed to the
best interests of the


                                3


<PAGE>




corporation, and, with respect to any criminal action or proceeding, he had
reasonable cause to believe that his conduct was unlawful.

	(2)	A corporation may indemnify or agree to indemnify any person
who was or is a party, or is threatened to be made a party, to any pending, or
completed action or suit by or in the right of the corporation to procure a
judgment in its favor, by reason of the fact that he is or was a director,
officer, employee, or agent of the corporation, or is or was serving at the
request of the corporation as a director, trustee, officer, employee, member,
manager or agent of another corporation, domestic or foreign, nonprofit or for
profit, a limited liability company, or a partnership, joint venture, trust,
or other enterprise, against expenses, including attorney's fees, actually and
reasonably incurred by him in connection with the defense or settlement of
such action or suit, if he acted in good faith and in a manner he reasonably
believed to be in or not opposed to the best interests of the corporation,
except that no indemnification shall be made in respect of any of the
following:

		(a)  Any claim, issue or matter as to which such person is
adjudged to be liable for negligence or misconduct in the performance of his
duty to the corporation unless, and only to the extent that, the court of
common pleas or the court in which such action or suit was brought determines,
upon application, that, despite the adjudication of liability, but in view of
all the circumstances of the case, such person is fairly and reasonably
entitled to indemnity for such expenses as the court of common pleas or such
other court shall deem proper.

		(b)  Any action or suit in which the only liability asserted
against a director is pursuant to section 1701.95 of the Revised Code.

	(3)	To the extent that a director, trustee, officer, employee,
member, manager, or agent has been successful on the merits or otherwise in
defense of any action, suit or proceeding referred to in division (E)(1) or
(2) of this section, or in defense of any claim, issue, or matter therein, he
shall be indemnified against expenses, including attorney's fees, actually and
reasonably incurred by him in connection with the action, suit, or proceeding.

	(4)	Any indemnification under division (E)(1) or (2) of this
section, unless ordered by a court, shall be made by the corporation only as
authorized in the specific case, upon a determination that indemnification of
the director, trustee, officer, employee, member, manager, or agent is proper
in the circumstances because he has met the applicable standard of conduct set
forth in division (E)(1) or (2) of this section.  Such determination shall be
made as follows:

		(a)  By a majority vote of a quorum consisting of directors of
the indemnifying corporation who were not and are not parties to or threatened
with the action, suit, or proceeding referred to in division (E)(1) or (2) of
this section;

		(b)  If the quorum described in division (E)(4)(a) of this
section is not obtainable or if a majority vote of a quorum of disinterested
directors so directs, in a written opinion by independent legal counsel other
than an attorney, or a firm having associated with it an attorney, who has been
retained by or who has performed services for the corporation or any person to
be indemnified within the past five years;

		(c)  By the shareholders;

		(d)  By the court of common pleas or the court in which the
action, suit, or proceeding referred to in division (E)(1) or (2) of this
section was brought.

	Any determination made by the disinterested directors under division
(E)(4)(a) or by independent legal counsel under division (E)(4)(b) of this
section shall be promptly communicated to the person who threatened or brought
the action or suit by or in the right of the corporation under division


                                4


<PAGE>




(E)(2) of this section, and, within ten days after receipt of such
notification, such person shall have the right to petition the court of common
pleas or the court in which such action or suit was brought to review the
reasonableness of such determination.

        (5) (a)  Unless at the time of a director's act or omission that is
the subject of an action, suit, or proceeding referred to in division (E)(1)
or (2) of this section, the articles or the regulations of a corporation state,
by specific reference to this division, that the provisions of this division
do not apply to the corporation and unless the only liability asserted against
a director in an action, suit, or proceeding referred to in division (E)(1) or
(2) of this section is pursuant to section 1701.95 of the Revised Code,
expenses, including attorney's fees, incurred by a director in defending the
action, suit, or proceeding shall be paid by the corporation as they are
incurred, in advance of the final disposition of the action, suit, or
proceeding, upon receipt of an undertaking by or on behalf of the director in
which he agrees to do both of the following:

		(i)  Repay such amount if it is proved by clear and convincing
evidence in a court of competent jurisdiction that his action or failure to
act involved an act or omission undertaken with deliberate intent to cause
injury to the corporation or undertaken with reckless disregard for the best
interests of the corporation;

		(ii)  Reasonably cooperate with the corporation concerning the
action, suit, or proceeding.

            (b)  Expenses, including attorney's fees, incurred by a director,
trustee, officer, employee, member, manager, or agent in defending any action,
suit, or proceeding referred to in division (E)(1) or (2) of this section, may
be paid by the corporation as they are incurred, in advance of the final
disposition of the action, suit, or proceeding, as authorized by the directors
in the specific case, upon receipt of an undertaking by or on behalf of the
director, trustee, officer, employee, member, manager, or agent to repay such
amount, if it ultimately is determined that he is not entitled to be
indemnified by the corporation.

	(6)	The indemnification authorized by this section shall not be
exclusive of, and shall be in addition to, any other rights granted to those
seeking indemnification under the articles, the regulations, any agreement, a
vote of shareholders or disinterested directors, or otherwise, both as to
action in their official capacities and as to action in another capacity while
holding their offices or position, and shall continue as to a person who has
ceased to be a director, trustee, officer, employee, member, manager or agent
and shall inure to the benefit of the heirs, executors, and administrators of
such a person.

	(7)	A corporation may purchase and maintain insurance or furnish
similar protection, including, but not limited to, trust funds, letters of
credit, or self-insurance, on behalf of or for any person who is or was a
director, officer, employee or agent of the corporation, or is or was serving
at the request of the corporation as a director, trustee, officer, employee,
member, manager, or agent of another corporation, domestic or foreign,
nonprofit or for profit, a limited liability company, or a partnership, joint
venture, trust, or other enterprise, against any liability asserted against
him and incurred by him in any such capacity, or arising out of his status as
such, whether or not the corporation would have the power to indemnify him
against such liability under this section.  Insurance may be purchased from
or maintained with a person in which the corporation has a financial interest.

	(8)	The authority of a corporation to indemnify persons pursuant
to division (E)(1) or (2) of this section does not limit the payment of
expenses as they are incurred, indemnification, insurance, or other protection
that may be provided pursuant to divisions (E)(5), (6) and (7) of this section.
Divisions (E)(1) and (2) of this section do not create any obligation to repay
or return payments made by the corporation pursuant to division (E)(5), (6) or
(7).

        (9)     As used in division (E) of this section, "corporation" includes
all constituent entities in a consolidation or merger and the new or surviving
corporation, so that any person who is or was a director, officer, employee,
trustee, member, manager, or agent of such a constituent entity, or is or was
serving at the request of such constituent entity as a director, trustee,
officer, employee, member, manager, or agent of another corporation, domestic
or foreign, nonprofit or for profit, a limited liability company, or a
partnership, joint venture, trust, or other enterprise, shall stand in the
same position under this section with respect to the new or surviving
corporation as he would if he had served the new or surviving corporation in
the same capacity.

        Article V of the Company's Code of Regulations provides as follows:

	SECTION 1.  MANDATORY INDEMNIFICATION.  The corporation shall indemnify
(A) any officer or director of the corporation and (B) any person (including an
officer or director of the corporation) who has served or is serving at the
request of the corporation as a director, trustee or officer of another
corporation (domestic or foreign, nonprofit or for profit), partnership, joint
venture, trust or other enterprise who was or is a party or is threatened to
be a party to any threatened, pending or completed action, suit or proceeding,
whether civil, criminal, administrative, or investigative (including, without
limitation, any action threatened or instituted by or in the right of the
corporation) by reason of the fact that he is or was a director, trustee,
officer, employee or agent of the corporation, or is or was serving at the
request of the corporation as a director, trustee, officer, employee or agent
of another corporation (domestic or foreign, nonprofit or for profit),
partnership, joint venture, trust or other enterprise, against expenses
(including, without limitation, attorneys' fees, filing fees, court reporters'
fees and transcript costs), judgments, fines and amounts paid in settlement
actually and reasonably incurred by him in connection with such action, suit
or proceeding if he acted in good faith and in a manner he reasonably believed
to be in or not opposed to the best interests of the corporation, and with
respect to any criminal action or proceeding, he had no reasonable cause to
believe his conduct was unlawful.  A person claiming indemnification under
this Section 1 shall be presumed in respect of any act or omission giving rise
to such claim for indemnification, to have acted in good faith and in a manner
he reasonably believed to be in or not opposed to the best interests of the
corporation, and with respect to any criminal matter, to have had no reasonable
cause to believe his conduct was unlawful, and the termination of any action,
suit, or proceeding by judgment, order, settlement, or conviction, or upon a
plea of nolo contendere or its equivalent, shall not, of itself, rebut such
presumption.


	SECTION 2.  COURT-APPROVED INDEMNIFICATION.  Anything contained in the
Regulations or elsewhere to the contrary notwithstanding:

	(A)  the corporation shall not indemnify (i) any officer or director
of the corporation, or (ii) any person (including an officer or director of
the corporation) who has served or is serving at the request of the corporation
as a director, trustee or officer of another corporation (domestic or foreign,
nonprofit or for profit), partnership, joint venture, trust or other
enterprise who was a party to any completed action or suit instituted by or
in the right of the corporation to procure a judgment in its favor by reason
of the fact that he is or was a director, officer, employee or agent of the
corporation, or is or was serving at the request of the corporation as a
director, trustee, officer, employee or agent of another corporation (domestic
or foreign, nonprofit or for profit), partnership, joint venture, trust or
other enterprise in respect of any claim, issue or matter asserted in such
action or suit as to which he shall have been adjudged to be liable for gross
negligence or misconduct (other than negligence) in the performance of his
duty to the corporation unless and only to the extent that the Court of Common
Pleas of Butler County, Ohio or the court in which such action or suit was
brought shall determine upon application that despite such adjudication of
liability, and in view of all the circumstances of the case, he is fairly and
reasonably entitled to such indemnity as such Court of Common Pleas or such
other court shall deem proper; and

	(B)  the corporation shall promptly make any such unpaid
indemnification as is determined by a court to be proper as contemplated by
this Section 2.


                                6


<PAGE>




	SECTION 3.  INDEMNIFICATION FOR EXPENSES.  Anything contained in the
Regulations or elsewhere to the contrary notwithstanding, to the extent that an
officer or director of the corporation or any person (including an officer or
director of the corporation) who has served or is serving at the request of
the corporation as a director, trustee or officer of another corporation
(domestic or foreign, nonprofit or for profit), partnership, joint venture,
trust or other enterprise has been successful on the merits or otherwise in
defense of any action, suit or proceeding referred to in Section 1, or in
defense of any claim, issue, or matter therein, he shall be promptly
indemnified by the corporation against expenses (including, without limitation,
attorneys' fees, filing fees, court reporters' fees and transcript costs)
actually and reasonably incurred by him in connection therewith.


	SECTION 4.  DETERMINATION REQUIRED.  Any indemnification required
under Section 1 and not precluded under Section 2 shall be made by the
corporation only upon a determination that such indemnification is proper in
the circumstances because the person has met the applicable standard of
conduct set forth in Section 1.  Such determination may be made only (A) by a
majority vote of a quorum consisting of directors of the corporation who were
not and are not parties to, or threatened with, any such action, suit or
proceeding or (B) if such a quorum is not obtainable or if a majority of a
quorum of disinterested directors so directs, in a written opinion by
independent legal counsel other than an attorney, or a firm having associated
with it an attorney, who has been retained by or who has performed services
for the corporation, or any person to be indemnified, within the past five
years or (C) by the shareholders or (D) by the Court of Common Pleas of Butler
County, Ohio or (if the corporation is a party thereto) the court in which such
action, suit or proceeding was brought, if any; any such determination
may be made by a court under subparagraph (D) of this Section at any time
(including, without limitation, any time before, during or after the time when
any such determination may be requested of, be under consideration by or have
been denied or disregarded by the disinterested directors under subparagraph
(A) or by independent legal counsel under subparagraph (B) or by the
shareholders under subparagraph (C) of this Section); and no failure for any
reason to make any such determination, and no decision for any reason to deny
any such determination, by the disinterested directors under subparagraph (A)
or by independent legal counsel under subparagraph (B) or by shareholders
under subparagraph (C) of this Section shall be evidence in rebuttal of the
presumption recited in Section 1.  Any determination made by the disinterested
directors under subparagraph (A) of this Section or by independent legal
counsel under subparagraph (B) of this Section to make indemnification in
respect of any claim, issue or matter asserted in an action or suit threatened
or brought by or in the right of the corporation shall be promptly
communicated to the person who threatened or brought such action or suit, and
within ten (10) days after receipt of such notification such person shall have
the right to petition the Court of Common Pleas of Butler County, Ohio or the
court in which such action or suit was brought, if any, to review the
reasonableness of such determination.


	SECTION 5.  ADVANCES FOR EXPENSES.  Expenses (including, without
limitation, attorneys' fees, filing fees, court reporters' fees and transcript
costs) incurred in defending any action, suit or proceeding referred to in
Section 1 shall be paid by the corporation in advance of the final disposition
of such action, suit or proceeding to or on behalf of the officer, director or
other person entitled to indemnity under Section 1 promptly as such expenses
are incurred by him, but only if such officer, director or other person shall
first agree, in writing, to repay all amounts so paid in respect of any claim,
issue or other matter asserted in such action, suit or proceeding in defense
of which he shall not have been successful on the merits or otherwise:

	(A) unless it shall ultimately be determined as provided in Section 4
that he is not entitled to be indemnified by the corporation as provided under
Section 1; or

	(B) if, in respect of any claim, issue or other matter asserted by or
in the right of the corporation in such action or suit, he shall have been
adjudged to be liable for gross negligence or misconduct (other than
negligence) in the performance of his duty to the corporation, unless and
only to



                                7


<PAGE>




the extent that the Court of Common Pleas of Butler County, Ohio or the court
in which such action or suit was brought shall determine upon application that,
despite such adjudication of liability, and in view of all the circumstances,
he is fairly and reasonably entitled to all or part of such indemnification.


	SECTION 6.  ARTICLE V NOT EXCLUSIVE.  The indemnification provided by
this Article V shall not be deemed exclusive of any other rights to which any
person seeking indemnification may be entitled under the Articles or the
Regulations or any agreement, vote of shareholders of the corporation or
disinterested directors, or otherwise, both as to action in his official
capacity and as to action in another capacity while holding such office, and
shall continue as to a person who has ceased to be an officer or director of
the corporation and shall inure to the benefit of the heirs, executors, and
administrators of such a person.


	SECTION 7.  INSURANCE.  The corporation may purchase and maintain
insurance on behalf of any person who is or was a director, trustee, officer,
employee or agent of the corporation, or is or was serving at the request of
the corporation as a director, trustee, officer, employee, or agent of another
corporation (domestic or foreign, nonprofit or for profit), partnership, joint
venture, trust, or other enterprise, against any liability asserted against
him and incurred by him in any such capacity, or arising out of his status as
such, whether or not the corporation would have the obligation or the power to
indemnify him against such liability under the provisions of this Article V.


	SECTION 8.  CERTAIN DEFINITIONS.  For purposes of this Article V, and
as examples and not by way of limitation:

	(A)  A person claiming indemnification under this Article V shall be
deemed to have been successful on the merits or otherwise in defense of any
action, suit or proceeding referred to in Section 1, or in defense of any
claim, issue or other matter therein, if such action, suit or proceeding shall
be terminated as to such person, with or without prejudice, without the entry
of a judgment or order against him, without a conviction of him, without the
imposition of a fine upon him, and without his payment or agreement to pay any
amount in settlement thereof (whether or not any such termination is based
upon a judicial or other determination of lack of merit of the claims made
against him or otherwise results in a vindication of him); and

        (B)  References to an "other enterprise" shall include employee benefit
plans; references to a "fine" shall include any excise taxes assessed on a
person with respect to an employee benefit plan; and references to "serving at
the request of the corporation" shall include any service as a director,
officer, employee or agent of the corporation which imposes duties on, or
involves services by, such director, officer, employee or agent with respect
to an employee benefit plan, its participants or beneficiaries; and a person
who acted in good faith and in a manner he reasonably believed to be in the
best interests of the participants and beneficiaries of an employee benefit
plan shall be deemed to have acted in a manner "not opposed to the best
interest of the corporation" within the meaning of that term as used in this
Article V.


	SECTION 9.  VENUE.  Any action, suit or proceeding to determine a
claim for indemnification under this Article V may be maintained by the person
claiming such indemnification, or by the corporation, in the Court of Common
Pleas of Butler County, Ohio.  The corporation and (by claiming such
indemnification) each such person consent to the exercise of jurisdiction over
its or his person by the Court of Common Pleas of Butler County, Ohio in any
such action, suit or proceeding.

	The Company has in force and effect a policy insuring the directors
and officers of the Company against losses which they or any of them shall
become legally obligated to pay for any reason of any actual or alleged error
or misstatement or misleading statement or act or omission or neglect or
breach of duty by the directors and officers in the discharge of their duties,
individually or collectively, or any matter claimed against them solely by
reason of their being directors or officers, such coverage being limited by
the specific terms and provisions of the insurance policy.

Item. 9.	Undertakings.

	(1)	The undersigned Registrant hereby undertakes:

		(a)	To file, during any period in which offers or sales
                        are being made, a post-effective amendment to this
                        registration statement:

			(i)	To include any prospectus required by section
                        10(a)(3) of the Securities Act;

			(ii)	To reflect in the prospectus any facts or
                        events arising after the effective date of the
                        registration statement (or the most recent post-
                        effective amendment thereof) which, individually or
                        in the aggregate, represent a fundamental change in
                        the information set forth in the registration
                        statement.  Notwithstanding the foregoing, any
                        increase or decrease in volume of securities offered
                        (if the total dollar value of securities offered would
                        not exceed that which was registered) and any deviation
                        from the low or high and of the estimated maximum
                        offering range may be reflected in the form of
                        prospectus filed with the Commission pursuant to Rule
                        424(b) if, in the aggregate, the changes in volume and
                        price represent no more than a 20 percent change in the
                        maximum aggregate offering price set forth in the
                        "Calculation of Registration Fee" table in the
                        effective registration statement;

                        (iii)   To include any material information with
                        respect to the plan of distribution not previously
                        disclosed in the registration statement or any
                        material change to such information in the
                        registration statement;

		provided, however, that paragraphs (1)(a)(i) and (1)(a)(ii) do
not apply if the information required to be included in a post-effective
amendment by those paragraphs is contained in periodic reports filed by the
Registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that
are incorporated by reference in this registration statement.

		(b)	That, for the purpose of determining any liability
                        under the Securities Act, each such post-effective
                        amendment shall be deemed to be a new registration
                        statement relating to the securities offered therein,
                        and the offering of such securities at that time shall
                        be deemed to be the initial bona fide offering thereof.

		(c)	To remove from registration by means of a post-
                        effective amendment any of the securities being
                        registered which remain unsold at the termination of
                        the offering.



                                10

<PAGE>



          (2)   The undersigned Registrant hereby undertakes that, for purposes
of determining any liability under the Securities Act, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Exchange Act that is incorporated by reference in the Registration Statement
shall be deemed to be a new registration statement relating to the securities
offered therein, and the offering of such securities at that time shall be
deemed to be the initial bona fide offering thereof.

          (3)	Insofar as indemnification for liabilities arising under the
Securities Act may be permitted to directors, officers and controlling persons
of the Registrant pursuant to the foregoing provisions, or otherwise, the
Registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Securities Act and is, therefore, unenforceable.  In the event that a claim
for indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.

	Pursuant to the requirements of the Securities Act of 1933, Ohio

Item 6.	Indemnification of Directors and Officers.

	Division (E) of Section 1701.13 of the Ohio Revised Code and Article V
of the Code of Regulations of Ohio Casualty Corporation (the "Company") relate
to indemnification of the Company's directors and officers against liabilities
arising in connection with the performance of their respective duties.

	Division (E) of Section 1701.13 of the Ohio Revised Code provides as
follows:

	(E) (1)  A corporation may indemnify or agree to indemnify any person
who was or is a party, or is threatened to be made a party, to any pending, or
completed action, suit, or proceeding, whether civil, criminal, administrative,
or investigative, other than an action by or in the right of the corporation,
by reason of the fact that he is or was a director, officer, employee, or
agent of the corporation, or is or was serving at the request of the
corporation as a director, trustee, officer, employee, member, manager, or
agent of another corporation, domestic or foreign, nonprofit or for profit, a
limited liability company, or a partnership, joint venture, trust, or other
enterprise, against expenses, including attorney's fees, judgments, fines and
amounts paid in settlement actually and reasonably incurred by him in
connection with such action, suit, or proceeding, if he acted in good faith
and in a manner he reasonably believed to be in or not opposed to the best
interests of the corporation, and, with respect to any criminal action or
proceeding, if he had no reasonable cause to believe his conduct was unlawful.
The termination of any action, suit, or proceeding by judgment, order,
settlement, or conviction, or upon a plea of nolo contendere or its equivalent,
shall not, of itself, create a presumption that the person did not act in good
faith and in a manner he reasonably believed to be in or not opposed to the
best interests of the

                                3
corporation, and, with respect to any criminal action or proceeding, he had
reasonable cause to believe that his conduct was unlawful.

	(2)	A corporation may indemnify or agree to indemnify any person
who was or is a party, or is threatened to be made a party, to any pending, or
completed action or suit by or in the right of the corporation to procure a
judgment in its favor, by reason of the fact that he is or was a director,
officer, employee, or agent of the corporation, or is or was serving at the
request of the corporation as a director, trustee, officer, employee, member,
manager or agent of another corporation, domestic or foreign, nonprofit or for
profit, a limited liability company, or a partnership, joint venture, trust,
or other enterprise, against expenses, including attorney's fees, actually and
reasonably incurred by him in connection with the defense or settlement of
such action or suit, if he acted in good faith and in a manner he reasonably
believed to be in or not opposed to the best interests of the corporation,
except that no indemnification shall be made in respect of any of the
following:

		(a)  Any claim, issue or matter as to which such person is
adjudged to be liable for negligence or misconduct in the performance of his
duty to the corporation unless, and only to the extent that, the court of
common pleas or the court in which such action or suit was brought determines,
upon application, that, despite the adjudication of liability, but in view of
all the circumstances of the case, such person is fairly and reasonably
entitled to indemnity for such expenses as the court of common pleas or such
other court shall deem proper.

		(b)  Any action or suit in which the only liability asserted
against a director is pursuant to section 1701.95 of the Revised Code.

	(3)	To the extent that a director, trustee, officer, employee,
member, manager, or agent has been successful on the merits or otherwise in
defense of any action, suit or proceeding referred to in division (E)(1) or
(2) of this section, or in defense of any claim, issue, or matter therein, he
shall be indemnified against expenses, including attorney's fees, actually and
reasonably incurred by him in connection with the action, suit, or proceeding.

	(4)	Any indemnification under division (E)(1) or (2) of this
section, unless ordered by a court, shall be made by the corporation only as
authorized in the specific case, upon a determination that indemnification of
the director, trustee, officer, employee, member, manager, or agent is proper
in the circumstances because he has met the applicable standard of conduct set
forth in division (E)(1) or (2) of this section.  Such determination shall be
made as follows:

		(a)  By a majority vote of a quorum consisting of directors of
the indemnifying corporation who were not and are not parties to or threatened
with the action, suit, or proceeding referred to in division (E)(1) or (2) of
this section;

		(b)  If the quorum described in division (E)(4)(a) of this
section is not obtainable or if a majority vote of a quorum of disinterested
directors so directs, in a written opinion by independent legal counsel other
than an attorney, or a firm having associated with it an attorney, who has been
retained by or who has performed services for the corporation or any person to
be indemnified within the past five years;

		(c)  By the shareholders;

		(d)  By the court of common pleas or the court in which the
action, suit, or proceeding referred to in division (E)(1) or (2) of this
section was brought.

	Any determination made by the disinterested directors under division
(E)(4)(a) or by independent legal counsel under division (E)(4)(b) of this
section shall be promptly communicated to the person who threatened or brought
the action or suit by or in the right of the corporation under division

                                4
(E)(2) of this section, and, within ten days after receipt of such
notification, such person shall have the right to petition the court of common
pleas or the court in which such action or suit was brought to review the
reasonableness of such determination.

        (5) (a)  Unless at the time of a director's act or omission that is
the subject of an action, suit, or proceeding referred to in division (E)(1)
or (2) of this section, the articles or the regulations of a corporation state,
by specific reference to this division, that the provisions of this division
do not apply to the corporation and unless the only liability asserted against
a director in an action, suit, or proceeding referred to in division (E)(1) or
(2) of this section is pursuant to section 1701.95 of the Revised Code,
expenses, including attorney's fees, incurred by a director in defending the
action, suit, or proceeding shall be paid by the corporation as they are
incurred, in advance of the final disposition of the action, suit, or
proceeding, upon receipt of an undertaking by or on behalf of the director in
which he agrees to do both of the following:

		(i)  Repay such amount if it is proved by clear and convincing
evidence in a court of competent jurisdiction that his action or failure to
act involved an act or omission undertaken with deliberate intent to cause
injury to the corporation or undertaken with reckless disregard for the best
interests of the corporation;

		(ii)  Reasonably cooperate with the corporation concerning the
action, suit, or proceeding.

            (b)  Expenses, including attorney's fees, incurred by a director,
trustee, officer, employee, member, manager, or agent in defending any action,
suit, or proceeding referred to in division (E)(1) or (2) of this section, may
be paid by the corporation as they are incurred, in advance of the final
disposition of the action, suit, or proceeding, as authorized by the directors
in the specific case, upon receipt of an undertaking by or on behalf of the
director, trustee, officer, employee, member, manager, or agent to repay such
amount, if it ultimately is determined that he is not entitled to be
indemnified by the corporation.

	(6)	The indemnification authorized by this section shall not be
exclusive of, and shall be in addition to, any other rights granted to those
seeking indemnification under the articles, the regulations, any agreement, a
vote of shareholders or disinterested directors, or otherwise, both as to
action in their official capacities and as to action in another capacity while
holding their offices or position, and shall continue as to a person who has
ceased to be a director, trustee, officer, employee, member, manager or agent
and shall inure to the benefit of the heirs, executors, and administrators of
such a person.

	(7)	A corporation may purchase and maintain insurance or furnish
similar protection, including, but not limited to, trust funds, letters of
credit, or self-insurance, on behalf of or for any person who is or was a
director, officer, employee or agent of the corporation, or is or was serving
at the request of the corporation as a director, trustee, officer, employee,
member, manager, or agent of another corporation, domestic or foreign,
nonprofit or for profit, a limited liability company, or a partnership, joint
venture, trust, or other enterprise, against any liability asserted against
him and incurred by him in any such capacity, or arising out of his status as
such, whether or not the corporation would have the power to indemnify him
against such liability under this section.  Insurance may be purchased from
or maintained with a person in which the corporation has a financial interest.

	(8)	The authority of a corporation to indemnify persons pursuant
to division (E)(1) or (2) of this section does not limit the payment of
expenses as they are incurred, indemnification, insurance, or other protection
that may be provided pursuant to divisions (E)(5), (6) and (7) of this section.
Divisions (E)(1) and (2) of this section do not create any obligation to repay
or return payments made by the corporation pursuant to division (E)(5), (6) or
(7).

                                5
(9)     As used in division (E) of this section, "corporation" includes
all constituent entities in a consolidation or merger and the new or surviving
corporation, so that any person who is or was a director, officer, employee,
trustee, member, manager, or agent of such a constituent entity, or is or was
serving at the request of such constituent entity as a director, trustee,
officer, employee, member, manager, or agent of another corporation, domestic
or foreign, nonprofit or for profit, a limited liability company, or a
partnership, joint venture, trust, or other enterprise, shall stand in the
same position under this section with respect to the new or surviving
corporation as he would if he had served the new or surviving corporation in
the same capacity.

        Article V of the Company's Code of Regulations provides as follows:

	SECTION 1.  MANDATORY INDEMNIFICATION.  The corporation shall indemnify
(A) any officer or director of the corporation and (B) any person (including an
officer or director of the corporation) who has served or is serving at the
request of the corporation as a director, trustee or officer of another
corporation (domestic or foreign, nonprofit or for profit), partnership, joint
venture, trust or other enterprise who was or is a party or is threatened to
be a party to any threatened, pending or completed action, suit or proceeding,
whether civil, criminal, administrative, or investigative (including, without
limitation, any action threatened or instituted by or in the right of the
corporation) by reason of the fact that he is or was a director, trustee,
officer, employee or agent of the corporation, or is or was serving at the
request of the corporation as a director, trustee, officer, employee or agent
of another corporation (domestic or foreign, nonprofit or for profit),
partnership, joint venture, trust or other enterprise, against expenses
(including, without limitation, attorneys' fees, filing fees, court reporters'
fees and transcript costs), judgments, fines and amounts paid in settlement
actually and reasonably incurred by him in connection with such action, suit
or proceeding if he acted in good faith and in a manner he reasonably believed
to be in or not opposed to the best interests of the corporation, and with
respect to any criminal action or proceeding, he had no reasonable cause to
believe his conduct was unlawful.  A person claiming indemnification under
this Section 1 shall be presumed in respect of any act or omission giving rise
to such claim for indemnification, to have acted in good faith and in a manner
he reasonably believed to be in or not opposed to the best interests of the
corporation, and with respect to any criminal matter, to have had no reasonable
cause to believe his conduct was unlawful, and the termination of any action,
suit, or proceeding by judgment, order, settlement, or conviction, or upon a
plea of nolo contendere or its equivalent, shall not, of itself, rebut such
presumption.

	SECTION 2.  COURT-APPROVED INDEMNIFICATION.  Anything contained in the
Regulations or elsewhere to the contrary notwithstanding:

	(A)  the corporation shall not indemnify (i) any officer or director
of the corporation, or (ii) any person (including an officer or director of
the corporation) who has served or is serving at the request of the corporation
as a director, trustee or officer of another corporation (domestic or foreign,
nonprofit or for profit), partnership, joint venture, trust or other
enterprise who was a party to any completed action or suit instituted by or
in the right of the corporation to procure a judgment in its favor by reason
of the fact that he is or was a director, officer, employee or agent of the
corporation, or is or was serving at the request of the corporation as a
director, trustee, officer, employee or agent of another corporation (domestic
or foreign, nonprofit or for profit), partnership, joint venture, trust or
other enterprise in respect of any claim, issue or matter asserted in such
action or suit as to which he shall have been adjudged to be liable for gross
negligence or misconduct (other than negligence) in the performance of his
duty to the corporation unless and only to the extent that the Court of Common
Pleas of Butler County, Ohio or the court in which such action or suit was
brought shall determine upon application that despite such adjudication of
liability, and in view of all the circumstances of the case, he is fairly and
reasonably entitled to such indemnity as such Court of Common Pleas or such
other court shall deem proper; and

	(B)  the corporation shall promptly make any such unpaid
indemnification as is determined by a court to be proper as contemplated by
this Section 2.

                                6
SECTION 3.  INDEMNIFICATION FOR EXPENSES.  Anything contained in the
Regulations or elsewhere to the contrary notwithstanding, to the extent that an
officer or director of the corporation or any person (including an officer or
director of the corporation) who has served or is serving at the request of
the corporation as a director, trustee or officer of another corporation
(domestic or foreign, nonprofit or for profit), partnership, joint venture,
trust or other enterprise has been successful on the merits or otherwise in
defense of any action, suit or proceeding referred to in Section 1, or in
defense of any claim, issue, or matter therein, he shall be promptly
indemnified by the corporation against expenses (including, without limitation,
attorneys' fees, filing fees, court reporters' fees and transcript costs)
actually and reasonably incurred by him in connection therewith.

	SECTION 4.  DETERMINATION REQUIRED.  Any indemnification required
under Section 1 and not precluded under Section 2 shall be made by the
corporation only upon a determination that such indemnification is proper in
the circumstances because the person has met the applicable standard of
conduct set forth in Section 1.  Such determination may be made only (A) by a
majority vote of a quorum consisting of directors of the corporation who were
not and are not parties to, or threatened with, any such action, suit or
proceeding or (B) if such a quorum is not obtainable or if a majority of a
quorum of disinterested directors so directs, in a written opinion by
independent legal counsel other than an attorney, or a firm having associated
with it an attorney, who has been retained by or who has performed services
for the corporation, or any person to be indemnified, within the past five
years or (C) by the shareholders or (D) by the Court of Common Pleas of Butler
County, Ohio or (if the corporation is a party thereto) the court in which such
action, suit or proceeding was brought, if any; any such determination
may be made by a court under subparagraph (D) of this Section at any time
(including, without limitation, any time before, during or after the time when
any such determination may be requested of, be under consideration by or have
been denied or disregarded by the disinterested directors under subparagraph
(A) or by independent legal counsel under subparagraph (B) or by the
shareholders under subparagraph (C) of this Section); and no failure for any
reason to make any such determination, and no decision for any reason to deny
any such determination, by the disinterested directors under subparagraph (A)
or by independent legal counsel under subparagraph (B) or by shareholders
under subparagraph (C) of this Section shall be evidence in rebuttal of the
presumption recited in Section 1.  Any determination made by the disinterested
directors under subparagraph (A) of this Section or by independent legal
counsel under subparagraph (B) of this Section to make indemnification in
respect of any claim, issue or matter asserted in an action or suit threatened
or brought by or in the right of the corporation shall be promptly
communicated to the person who threatened or brought such action or suit, and
within ten (10) days after receipt of such notification such person shall have
the right to petition the Court of Common Pleas of Butler County, Ohio or the
court in which such action or suit was brought, if any, to review the
reasonableness of such determination.

	SECTION 5.  ADVANCES FOR EXPENSES.  Expenses (including, without
limitation, attorneys' fees, filing fees, court reporters' fees and transcript
costs) incurred in defending any action, suit or proceeding referred to in
Section 1 shall be paid by the corporation in advance of the final disposition
of such action, suit or proceeding to or on behalf of the officer, director or
other person entitled to indemnity under Section 1 promptly as such expenses
are incurred by him, but only if such officer, director or other person shall
first agree, in writing, to repay all amounts so paid in respect of any claim,
issue or other matter asserted in such action, suit or proceeding in defense
of which he shall not have been successful on the merits or otherwise:

	(A) unless it shall ultimately be determined as provided in Section 4
that he is not entitled to be indemnified by the corporation as provided under
Section 1; or

	(B) if, in respect of any claim, issue or other matter asserted by or
in the right of the corporation in such action or suit, he shall have been
adjudged to be liable for gross negligence or misconduct (other than
negligence) in the performance of his duty to the corporation, unless and
only to

                                7
the extent that the Court of Common Pleas of Butler County, Ohio or the court
in which such action or suit was brought shall determine upon application that,
despite such adjudication of liability, and in view of all the circumstances,
he is fairly and reasonably entitled to all or part of such indemnification.

	SECTION 6.  ARTICLE V NOT EXCLUSIVE.  The indemnification provided by
this Article V shall not be deemed exclusive of any other rights to which any
person seeking indemnification may be entitled under the Articles or the
Regulations or any agreement, vote of shareholders of the corporation or
disinterested directors, or otherwise, both as to action in his official
capacity and as to action in another capacity while holding such office, and
shall continue as to a person who has ceased to be an officer or director of
the corporation and shall inure to the benefit of the heirs, executors, and
administrators of such a person.

	SECTION 7.  INSURANCE.  The corporation may purchase and maintain
insurance on behalf of any person who is or was a director, trustee, officer,
employee or agent of the corporation, or is or was serving at the request of
the corporation as a director, trustee, officer, employee, or agent of another
corporation (domestic or foreign, nonprofit or for profit), partnership, joint
venture, trust, or other enterprise, against any liability asserted against
him and incurred by him in any such capacity, or arising out of his status as
such, whether or not the corporation would have the obligation or the power to
indemnify him against such liability under the provisions of this Article V.

	SECTION 8.  CERTAIN DEFINITIONS.  For purposes of this Article V, and
as examples and not by way of limitation:

	(A)  A person claiming indemnification under this Article V shall be
deemed to have been successful on the merits or otherwise in defense of any
action, suit or proceeding referred to in Section 1, or in defense of any
claim, issue or other matter therein, if such action, suit or proceeding shall
be terminated as to such person, with or without prejudice, without the entry
of a judgment or order against him, without a conviction of him, without the
imposition of a fine upon him, and without his payment or agreement to pay any
amount in settlement thereof (whether or not any such termination is based
upon a judicial or other determination of lack of merit of the claims made
against him or otherwise results in a vindication of him); and

        (B)  References to an "other enterprise" shall include employee benefit
plans; references to a "fine" shall include any excise taxes assessed on a
person with respect to an employee benefit plan; and references to "serving at
the request of the corporation" shall include any service as a director,
officer, employee or agent of the corporation which imposes duties on, or
involves services by, such director, officer, employee or agent with respect
to an employee benefit plan, its participants or beneficiaries; and a person
who acted in good faith and in a manner he reasonably believed to be in the
best interests of the participants and beneficiaries of an employee benefit
plan shall be deemed to have acted in a manner "not opposed to the best
interest of the corporation" within the meaning of that term as used in this
Article V.

	SECTION 9.  VENUE.  Any action, suit or proceeding to determine a
claim for indemnification under this Article V may be maintained by the person
claiming such indemnification, or by the corporation, in the Court of Common
Pleas of Butler County, Ohio.  The corporation and (by claiming such
indemnification) each such person consent to the exercise of jurisdiction over
its or his person by the Court of Common Pleas of Butler County, Ohio in any
such action, suit or proceeding.

	The Company has in force and effect a policy insuring the directors
and officers of the Company against losses which they or any of them shall
become legally obligated to pay for any reason of any actual or alleged error
or misstatement or misleading statement or act or omission or neglect or
breach of duty by the directors and officers in the discharge of their duties,
individually or collectively, or any matter claimed against them solely by
reason of their being directors or officers, such coverage being limited by
the specific terms and provisions of the insurance policy.

	(1)	The undersigned Registrant hereby undertakes:

		(a)	To file, during any period in which offers or sales
                        are being made, a post-effective amendment to this
                        registration statement:

			(i)	To include any prospectus required by section
                        10(a)(3) of the Securities Act;

			(ii)	To reflect in the prospectus any facts or
                        events arising after the effective date of the
                        registration statement (or the most recent post-
                        effective amendment thereof) which, individually or
                        in the aggregate, represent a fundamental change in
                        the information set forth in the registration
                        statement.  Notwithstanding the foregoing, any
                        increase or decrease in volume of securities offered
                        (if the total dollar value of securities offered would
                        not exceed that which was registered) and any deviation
                        from the low or high and of the estimated maximum
                        offering range may be reflected in the form of
                        prospectus filed with the Commission pursuant to Rule
                        424(b) if, in the aggregate, the changes in volume and
                        price represent no more than a 20 percent change in the
                        maximum aggregate offering price set forth in the
                        "Calculation of Registration Fee" table in the
                        effective registration statement;

                        (iii)   To include any material information with
                        respect to the plan of distribution not previously
                        disclosed in the registration statement or any
                        material change to such information in the
                        registration statement;

		provided, however, that paragraphs (1)(a)(i) and (1)(a)(ii) do
not apply if the information required to be included in a post-effective
amendment by those paragraphs is contained in periodic reports filed by the
Registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that
are incorporated by reference in this registration statement.

		(b)	That, for the purpose of determining any liability
                        under the Securities Act, each such post-effective
                        amendment shall be deemed to be a new registration
                        statement relating to the securities offered therein,
                        and the offering of such securities at that time shall
                        be deemed to be the initial bona fide offering thereof.

		(c)	To remove from registration by means of a post-
                        effective amendment any of the securities being
                        registered which remain unsold at the termination of
                        the offering.

                                10
(2)   The undersigned Registrant hereby undertakes that, for purposes
of determining any liability under the Securities Act, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Exchange Act that is incorporated by reference in the Registration Statement
shall be deemed to be a new registration statement relating to the securities
offered therein, and the offering of such securities at that time shall be
deemed to be the initial bona fide offering thereof.

          (3)	Insofar as indemnification for liabilities arising under the
Securities Act may be permitted to directors, officers and controlling persons
of the Registrant pursuant to the foregoing provisions, or otherwise, the
Registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Securities Act and is, therefore, unenforceable.  In the event that a claim
for indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.

                                SIGNATURES

	Pursuant to the requirements of the Securities Act of 1933, Ohio
Casualty Corporation certifies that it has reasonable grounds to believe that

this registration statement to be signed on its behalf by the undersigned,
thereunto duly authorized, in the City of Fairfield, State of Ohio, on this
19th day of May, 2005.
