Item 6. Indemnification of Directors and Officers.

        Article VII of the Corporation's Code of Regulations provides as
follows:

        The Corporation shall indemnify, to the full extent permitted or
authorized by the Ohio General Corporation Law as it may from time to time be
amended, any person made or threatened to be made a party to any threatened,
pending or completed action, suit or proceeding, whether civil, criminal,
administrative or investigative, by reason of the fact that he is or was a
director, officer or employee of the Corporation, or is or was serving at the
request of the Corporation as a director, trustee, officer or employee of
another corporation, partnership, joint venture, trust or other enterprise. The
indemnification provided by this Article VII shall not be deemed exclusive of
any other rights to which any person seeking indemnification may be entitled
under the articles of incorporation or the regulations, or any agreement, vote
of shareholders 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 a director,
trustee, officer or employee and shall inure to the benefit of the heirs,
executors and administrators of such a person.

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



                                      II-2

        (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 threatened,
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 attorneys' 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
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 threatened,
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 attorneys' 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;



                                      II-3

                (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 (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 positions, 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).



                                      II-4

        (9)     As used in this division, references to "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.

        Under the terms of an Indemnification Agreement, filed as Exhibit 10(c)
to the Registrant's Form 10-K for the fiscal year ended June 30, 2000, to which
reference is hereby made, each Director and certain officers of the Registrant
are indemnified against certain liabilities, including liabilities arising under
the Securities Act.

Item 9. Undertakings

  (a)   The undersigned Registrant hereby undertakes:

        (1)     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 of 1933;

                (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)



                                      II-5

                and any deviation from the low or high end 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 20% 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 (a)(1)(i) and (a)(1)(ii) do not apply if the
                Registration Statement is on Form S-3 or Form S-8, and 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 Securities Exchange Act of 1934 that are incorporated by
                reference in the Registration Statement.

        (2)     That, for the purpose of determining any liability under the
Securities Act of 1933, 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.

        (3)     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.

  (b)   The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the
Securities Exchange Act of 1934) 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.

  (c)   Insofar as indemnification for liabilities arising under the Securities
Act of 1933 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 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 Act and will be governed by the final adjudication of
