Item 6. Indemnification of Directors and Officers.
- --------------------------------------------------

                  Division (E) of Section 1701.13 of the Ohio Revised Code
governs indemnification by an Ohio corporation and 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 



                                       2
<PAGE>   3


        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 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
        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 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:



                                       3
<PAGE>   4


                      (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 


                                       4
<PAGE>   5


               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 (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.


                                       5
<PAGE>   6



               (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) 



                                       6
<PAGE>   7


        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 Five of the Regulations of the Registrant governs
indemnification by the Registrant and provides as follows:

               Section 5.01. MANDATORY INDEMNIFICATION. The corporation shall
        indemnify any officer or director of the corporation 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 (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, 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 



                                       7
<PAGE>   8


        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 5.01 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 5.02. COURT-APPROVED INDEMNIFICATION. Anything contained
        in the Regulations or elsewhere to the contrary notwithstanding:

               (A) the corporation shall not indemnify any officer or director
        of the corporation 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 acting with
        reckless disregard for the best interests of the corporation 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 Licking 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 5.02.

               Section 5.03. 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 has been
        successful on the merits or otherwise in defense of any action, suit or
        proceeding referred to in Section 5.01, 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, 


                                       8
<PAGE>   9


        court reporters' fees and transcript costs) actually and reasonably
        incurred by him in connection therewith.

               Section 5.04. DETERMINATION REQUIRED. Any indemnification
        required under Section 5.01 and not precluded under Section 5.02 shall
        be made by the corporation only upon a determination that such
        indemnification of the officer or director is proper in the
        circumstances because he has met the applicable standard of conduct set
        forth in Section 5.01. 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 Licking 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 division (D) of this Section 5.04 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
        division (A) or by independent legal counsel under division (B) or by
        the shareholders under division (C) of this Section 5.04]; 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 division (A) or by independent legal counsel under
        division (B) or by the shareholders under division (C) of this Section
        5.04 shall be evidence in rebuttal of the presumption recited in Section
        5.01. Any determination made by the disinterested directors under
        division (A) or by independent legal counsel under division (B) of this
        Section 5.04 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 Licking County, Ohio or the court
        in which such action or 


                                       9
<PAGE>   10


        suit was brought, if any, to review the reasonableness of such
        determination.

               Section 5.05. 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 5.01 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 or director promptly as such expenses are incurred
        by him, but only if such officer or director 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) if it shall ultimately be determined as provided in Section
        5.04 that he is not entitled to be indemnified by the corporation as
        provided under Section 5.01; 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 acting with reckless disregard for
        the best interests of the corporation 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 Licking 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 5.06. ARTICLE FIVE NOT EXCLUSIVE. The indemnification
        provided by this Article FIVE shall not be exclusive of, and shall be in
        addition to, any other rights to which any person seeking
        indemnification may be entitled under the Articles 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 an officer or director of the corporation
        and shall inure to the benefit of the heirs, executors, and
        administrators of such a person.

               Section 5.07. INSURANCE. The 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 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, 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 FIVE. Insurance may be purchased from or
        maintained with a person in which the corporation has a financial
        interest.

               Section 5.08. CERTAIN DEFINITIONS. For purposes of this Article
        FIVE, and as examples and not by way of limitation:

               (A) A person claiming indemnification under this Article FIVE
        shall be deemed to have been successful on the merits or otherwise in
        defense of any action, suit or proceeding referred to in Section 5.01,
        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 the 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 



                                       11
<PAGE>   12


        a manner "not opposed to the best interests of the corporation" within
        the meaning of that phrase as used in this Article FIVE.

               Section 5.09. VENUE. Any action, suit or proceeding to determine
        a claim for indemnification under this Article FIVE may be maintained by
        the person claiming such indemnification, or by the corporation, in the
        Court of Common Pleas of Licking 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
        Licking County, Ohio in any such action, suit or proceeding.

               The Registrant has purchased insurance coverage which insures
directors and officers against certain liabilities which might be incurred by
them in such capacities.

               Not Applicable.


Item 8.  Exhibits.

               See the Index to Exhibits attached hereto at page 17.


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; and


                                       12
<PAGE>   13



             (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 information required to be included in a
                post-effective amendment by those paragraphs is contained in
                periodic reports filed with or furnished to the Commission by
                the Registrant pursuant to Section 13 or Section 15(d) of the
                Securities Exchange Act of 1934 that are incorporated by
                reference in this 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 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 provisions described in Item
         6 of this Part II, 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 



                                       13
<PAGE>   14


         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 such issue.

the Registrant certifies that it has reasonable grounds to believe that it meets
all of the requirements for filing on Form S-8 and has duly caused this
Registration Statement to be signed on its behalf by the undersigned, thereunto

Board of Directors
Park National Corporation
50 North Third Street
Newark, Ohio  43055

Gentlemen:

                  We are familiar with the proceedings taken and proposed to be
taken by Park National Corporation, an Ohio corporation (the "Company"), in
connection with the adoption of an amendment to the Park National Corporation
1995 Incentive Stock Option Plan (as amended, the "1995 Plan"), to make an
additional 500,000 common shares, without par value (the "Common Shares"), of
the Company available pursuant to the 1995 Plan; the granting of options to
purchase Common Shares of the Company pursuant to the 1995 Plan; and the
issuance and sale of Common Shares of the Company upon the exercise of options
granted and to be granted under the 1995 Plan, as described in the Registration
Statement on Form S-8 (the "Registration Statement") to be filed with the
Securities and Exchange Commission on May 14, 1998. The purpose of the
Registration Statement is to register the additional 500,000 Common Shares
reserved for issuance under the 1995 Plan pursuant to the provisions of the
Securities Act of 1933, as amended, and the rules and regulations promulgated
thereunder.

                  In connection with this opinion, we have examined an original
or copy of, and have relied upon the accuracy of, without independent
verification or investigation: (a) the Registration Statement; (b) the 1995
Plan; (c) the Company's Articles of Incorporation, as amended; (d) the Company's
Regulations, as amended; and (e) certain proceedings of the directors and of the
shareholders of the Company. We have also relied upon such representations of
the Company and officers of the Company and such authorities of law as we have
deemed relevant as a basis for this opinion.

                  We have relied solely upon the examinations and inquiries
recited herein, and we have not undertaken any independent investigation to
determine the existence or absence of any facts, and no inference as to our
knowledge concerning such facts should be drawn.

                  Based upon and subject to the foregoing and the further
qualifications and limitations set forth below, as of the date hereof, we are of
the opinion that after the additional 500,000 Common Shares of the Company to be
registered under the Registration Statement have been issued and delivered by
the Company, upon the exercise of options granted under the 1995 Plan against
payment of the purchase price therefor, in accordance with the terms of the 1995
Plan, said Common Shares will be validly issued, fully paid and non-assessable,
assuming compliance with applicable federal and state securities laws.

                  Our opinion is limited to the General Corporation Law of Ohio
in effect as of the date hereof. This opinion is furnished by us solely for the
benefit of the Company in connection with the offering of the Common Shares
pursuant to the 1995 Plan and the filing of the Registration Statement and any
amendments thereto. This opinion may not be relied upon by any other person or
assigned, quoted or otherwise used without our specific written consent.

                  Notwithstanding the foregoing, we consent to the filing of
this opinion as an exhibit to the Registration Statement and to the reference to
us therein.

                                Very truly yours,



                                VORYS, SATER, SEYMOUR AND PEASE LLP

                        1995 INCENTIVE STOCK OPTION PLAN
                       (AS AMENDED THROUGH APRIL 20, 1998)


         1. PURPOSE. This 1995 Incentive Stock Option Plan (the "Plan") is
intended as an incentive to encourage stock ownership by key employees of Park
National Corporation, an Ohio corporation (the "Company"), and its subsidiaries
by granting such key employees incentive stock options to purchase Common Shares
of the Company so that they may acquire or increase and retain a proprietary
interest in the long-term growth and financial success of the Company and its
subsidiaries. The Plan is intended to promote and advance the interests of the
Company and its shareholders by encouraging such key employees to enter into or
remain in the employment of the Company and/or its subsidiaries and to put forth
maximum efforts for the long-term growth and financial success of the Company
and its subsidiaries.

         2. DEFINITIONS. For purposes of this Plan, the following terms when
capitalized shall have the meanings designated herein unless a different meaning

                  (b) A "Change in Control" shall be deemed to have occurred on

Company is not the continuing or surviving corporation or pursuant to which any
Common Shares would be converted into cash, securities or other property of
another corporation, other than a merger of the Company in which holders of
Common Shares immediately prior to the merger have the same proportionate
ownership of shares of the surviving corporation immediately after the merger as
immediately before, or (ii) to sell or otherwise dispose of substantially all
the assets of the Company.

                  (c) "Code" shall mean the Internal Revenue Code of 1986, as
amended, and the regulations and rulings thereunder. References to a particular

price for the Company's Common Shares as shown on the American Stock Exchange -
Composite Transactions on that date or, if no such sale occurred on that date,
then for the next preceding day on which a sale was made. If the Common Shares
shall no longer be traded on the American Stock Exchange, the Fair Market Value

Nasdaq Stock Market or on any securities exchange on which the Common Shares may
be listed on such date or, if there are no reported sales on such date, then the

transacted.

                  (j) "Incentive Option" shall mean an option granted under this
Plan which is an incentive stock option under the provisions of Section 422 of
the Code; and any provisions elsewhere in this Plan or in any such Incentive
Option which would prevent such option from being an incentive stock option may
be deleted and/or voided retroactively to the date of the granting of such
option, by the action of the Committee; and the Committee may retroactively add
provisions to this Plan or to any Incentive Option if necessary to qualify such
option as an incentive stock option.

                  (k) "Key Employee" shall mean any employee of the Company

424(f) of the Code.

         3. ELIGIBILITY. Any Key Employee, including those who are officers of
the Company, shall be eligible to receive Incentive Options pursuant to the Plan
if selected as a Participant. More than one Incentive Option may be granted to a
Key Employee.

         4. COMMON SHARES SUBJECT TO THE PLAN. Incentive Options may be granted
under this Plan only for Common Shares of the Company. The Common Shares to be
issued and delivered by the Company upon exercise of Incentive Options granted
under this Plan shall
<PAGE>   4

be treasury shares. The aggregate number of Common Shares or which Incentive
Options may be granted under the Plan shall be 700,000. If, during the term of
this Plan, there shall be a stock split, stock dividend, combination or exchange
of shares or other similar change in the Company's capitalization, the aggregate
number of Common Shares for which Incentive Options may be granted under this
Plan, the number of Common Shares subject to outstanding Incentive Options and
the option price per Common Share of outstanding Incentive Options shall be
appropriately and proportionately adjusted to reflect the same. If any
outstanding Incentive Option under this Plan for any reason expires or is
terminated without having been exercised in full, the Common Shares allocable to
the unexercised portion of such Incentive Option shall (unless the Plan shall
have been terminated) become available for subsequent grants of Incentive
Options under the Plan. No Incentive Option may be granted under this Plan which
could cause the maximum limit to be exceeded.

         5. ADMINISTRATION OF THE PLAN.

                  (a)    The Plan shall be administered by the Committee.

                  (b) The Committee shall select the Participants to receive
Incentive Options from among the Key Employees and shall grant to such
Participants Incentive Options under, and in accordance with, the provisions of
this Plan.

                  (c) Subject to the express provisions of this Plan, the
Committee shall have the authority to adopt administrative regulations and
procedures which are consistent with the terms of this Plan; to adopt and amend
such option agreements as it deems it advisable; to determine the terms and
provisions of such option agreements (including the number of Common Shares with
respect to which Incentive Options are granted to a Participant who is a Key
Employee, the option price for Common Shares and the date or dates when each
Incentive Option or parts of it may be exercised) -- which terms shall comply
with the requirements of Section 6 below; to construe and interpret such option
agreements; to impose such limitations and restrictions as are deemed necessary
or advisable by counsel for the Company so that compliance with the Federal
securities laws and with the securities laws of the various states may be
assured; and to make all other determinations necessary or advisable for
administering this Plan. Decisions by the Committee may be made either by a
majority of its members at a meeting of the Committee duly called and held or
without a meeting by a writing signed by all of the members of the Committee.
All decisions and interpretations made by the Committee shall be binding and
conclusive on all Participants, their legal representatives and beneficiaries.
No member of the Board or of the Committee shall be liable for any action or
determination made in good faith with respect to this Plan or any Incentive
Option granted under it.

                  (d) With respect to persons subject to Section 16 of the
Exchange Act, transactions under this Plan are intended to comply with all
applicable conditions of Rule 16b-3 under the Exchange Act. To the extent any
provision of this Plan or action by the Committee fails to so comply, it shall
be deemed null and void, to the extent permitted by law and deemed advisable by
the Committee.

                  (e) The Committee may designate any officers or employees of
the Company or its Subsidiaries to assist the Committee in the administration of
this Plan but the Committee may not delegate to them duties imposed on the
Committee under this Plan.

         6. TERMS AND CONDITIONS OF INCENTIVE OPTIONS. Incentive Options granted
under this Plan shall contain such terms as the Committee shall determine
subject to the following limitations and requirements:

                  (a) Option Price: Subject to the limitations of Subsection
6(g) below, the option price per Common Share of each Incentive Option shall be
equal to the Fair Market Value of the Company's Common Shares on the date of
grant of such Incentive Option.

                  (b) Period within which Incentive Option may be exercised:
Subject to the limitations of Subsections 6(c) and 6(g) below, each Incentive
Option granted under this Plan shall terminate (become non-exercisable) on the
fifth anniversary of the day immediately preceding the date of grant of such
Incentive Option.

                  (c) Termination of Incentive Options by reason of termination
of employment: If a Participant's employment with the Company and its
Subsidiaries terminates for any reason other than the death, Disability or
Normal Retirement of the Participant, all of such Participant's Incentive
Options shall terminate effective immediately upon termination of employment. If
the termination of employment was due to the Normal Retirement of the
Participant, such Incentive Options may be exercised in full, whether or not
then exercisable by their terms, and the right of the Participant to exercise
the Incentive Options shall terminate upon the earlier to occur of the
expiration of the term of the Incentive Options or three months after the date
of termination of employment. If the termination of employment was due to the
death of a Participant who was an employee of the Company and/or any Subsidiary
at the time of his death, such Incentive Options may be exercised in full,
whether or not then exercisable by their terms, and the right of the
representative or representatives of the Participant's estate (or the person or
persons who acquire (by bequest or inheritance) the rights to exercise the
Participant's Incentive Options) to exercise the Incentive Options shall
terminate upon the earlier to occur of the expiration of the term of the
Incentive Options or one year after the date of death. If the termination of
employment was due to the Disability of the Participant, such Incentive Options
may be exercised in full, whether or not then exercisable by their terms, and
the right of the Participant to exercise the Incentive Options shall terminate
upon the earlier to occur of the expiration of the term of the Incentive Options
or one year after the date of termination of employment. For purposes of this
Subsection 6(c), the date of termination of employment shall be the last day of
employment.

                  (d) Non-transferability: No Incentive Option granted under
this Plan shall be assignable or transferable except, in the event of the death
of a Participant, by his will or by the laws of descent and distribution. An
Incentive Option granted under this Plan shall be exercisable, during a
Participant's lifetime, only by him. In the event the death of a Participant
occurs, the representative or representatives of his estate, or the person or
persons who acquire (by bequest or inheritance) the rights to exercise his
Incentive Options granted under this Plan, may exercise any of the unexercised
Incentive Options or parts thereof prior to the expiration of the applicable
exercise period, as specified in Subsection 6(b), 6(c) or 6(g) of this Plan.

                  (e) Aggregate annual limit on Incentive Options: The aggregate
Fair Market Value (determined at the time of the grant of the Incentive Option)
of the Common Shares with respect to
<PAGE>   6


which Incentive Options are first exercisable by any Key Employee in any
calendar year under this Plan and all other plans of the Company and its
Subsidiaries shall not exceed $100,000.

                  (f) Partial Exercise: Unless otherwise provided in the
applicable option agreement, any exercise of an Incentive Option granted under
this Plan may be made in whole or in part; provided, however, that no single
purchase of Common Shares upon exercise of an Incentive Option shall be for less
than the lesser of (i) 200 Common Shares or (ii) the number of Common Shares
covered by the Incentive Option.

                  (g) 10% Shareholder: If a Participant owns (including
constructive ownership pursuant to Section 424(d) of the Code) more than ten
percent (10%) of the total combined voting power of all classes of stock of the
Company or any of its Subsidiaries, then each Incentive Option granted under
this Plan to such Participant shall by its terms fix the option price per Common
Share to be at least 110% of the Fair Market Value of the Common Shares on the
date of grant of such Incentive Option and such Incentive Option shall terminate
(become non-exercisable) on the fifth anniversary of the day immediately
preceding the date of grant of such Incentive Option.

                  (h) Exercisability: Incentive Options granted to Key Employees
under the Plan shall be exercisable at such times and subject to such
restrictions and conditions as the Committee may impose at the time of grant of
such Incentive Options.

                  (i) Restrictions on resale or other disposition: At the time
of exercise of any Incentive Option, the Participant exercising such Incentive
Option shall enter into an agreement with the Company pursuant to which the
Common Shares acquired upon the exercise of the Incentive Option may not be sold
or otherwise disposed of by the Participant to any person other than the Company
for a period of five years after the date of exercise; provided, however, that
this restriction shall not apply in the event of the exercise of an Incentive
Option following the death, Disability or Normal Retirement of a Participant. In
the event that a Participant who acquired Common Shares upon the exercise of an
Incentive Option subsequently leaves the employ of the Company and/or its
Subsidiaries for any reason other than death, Disability or Normal Retirement,
and such Participant desires to sell or otherwise dispose of the Common Shares
so acquired prior to the termination of the five-year restriction period, such
Participant shall submit a written request to the Company to purchase such
Common Shares at a purchase price equal to the lesser of the option price at
which such Common Shares were purchased or the Fair Market Value of the Common
Shares on the date such individual's employment terminated.

                  (j) Reload Options: Upon the exercise by a Participant of an
Incentive Option (the "Original Option") in full or in part, the Committee shall
automatically grant to such Participant a new Incentive Option (a "Reload
Option") covering the same number of Common Shares as were the subject of the
exercise; provided, however, that (I) no Participant may be granted Reload
Options in any one year of the term of the Original Option as established on the
date of grant of the Original Option covering, with respect to all Reload
Options granted in such one year, more than the number of Common Shares which
were subject to the Original Option on the date of grant of such Original
Option; and (II) the number of Common Shares which would otherwise be covered by
a Reload Option granted to a Participant (whether upon exercise of an Original
Option or upon exercise of a
<PAGE>   7

previously-granted Reload Option) shall be reduced to the extent necessary to
ensure that the aggregate annual limit on Incentive Options specified in
Subsection 6(e) of this Plan is not exceeded. Notwithstanding anything in this
Section to the contrary, no Participant, or person who has acquired the right to
exercise a Participant's Incentive Options upon the Participant's death, who
exercises an Incentive Option upon or after termination of the Participant's
employment by reason of death, Disability or Normal Retirement, shall be granted
any Reload Options in connection with such exercise. In addition, no Reload
Options shall be granted with respect to Original Options exercised on or after
January 16, 2005.

         7. PERIOD FOR GRANTING INCENTIVE OPTIONS. No Incentive Options shall be
granted under this Plan subsequent to the tenth anniversary of the day prior to
the date on which this Plan is adopted by the Board.

         8. NO EFFECT UPON EMPLOYMENT STATUS. The fact that an employee has been
designated a Key Employee or selected as a Participant shall not limit or
otherwise qualify the right of his employer to terminate his employment at any
time.

         9. METHOD OF EXERCISE. An Incentive Option granted under this Plan may
be exercised only by written notice to the Committee, signed by the Participant,
or in the event of his death, by such other person as is entitled to exercise
such Incentive Option. The notice of exercise shall state the number of Common
Shares in respect of which the Incentive Option is being exercised, and shall be
accompanied by the payment in cash or in check payable to the order of the
Company of an amount equal to the option price for the Common Shares being
purchased, all in accordance with such regulations, procedures and
determinations as may be adopted by the Committee pursuant to Subsection 5(c)
above. A certificate or certificates for the Common Shares purchased through the
exercise of an Incentive Option shall be issued in regular course after the
exercise of the Incentive Option and payment therefor. During the option period,
no person entitled to exercise any Incentive Option granted under this Plan
shall have any of the rights or privileges of a shareholder with respect to any
Common Shares issuable upon exercise of such Incentive Option until certificates
representing such Common Shares shall have been issued and delivered.

         10. IMPLIED CONSENT OF PARTICIPANTS. Every Participant, by his
acceptance of an Incentive Option under this Plan, shall be deemed to have
consented to be bound, on his own behalf and on behalf of his heirs, permitted
assigns and legal representatives, by all of the terms and conditions of this
Plan.

         11. CHANGE IN CONTROL. Upon the occurrence of a Change in Control, all
Incentive Options then outstanding under this Plan shall become exercisable in
full, whether or not then otherwise exercisable.

         12. COMPANY RESPONSIBILITY. All expenses of this Plan, including the
cost of maintaining records, shall be borne by the Company. The Company shall
have no responsibility or liability (other than under applicable securities
laws) for any act or thing done or left undone with respect to the price, time,
quantity or other conditions and circumstances of the purchase of Common Shares
under the terms of this Plan, so long as the Company acts in good faith.
<PAGE>   8


         13. SECURITIES LAW RESTRICTIONS. The Committee shall take all necessary
or appropriate action to ensure that all option grants and all exercises of
options under this Plan are in full compliance with all Federal and state
securities laws. No Incentive Option granted under this Plan shall be
exercisable before the Common Shares subject to this Plan have been registered
or qualified for sale under appropriate Federal and state securities laws.

         14. OPTION AGREEMENT. Each Participant receiving an Incentive Option
under this Plan shall enter into an agreement with the Company in a form
specified by the Committee agreeing to the terms and conditions of the Incentive
Option and such related matters as the Committee shall, in its sole discretion,
determine.

         15. AMENDMENT AND TERMINATION OF THE PLAN. The Committee, with the
approval of the Board, may amend the Plan from time to time or terminate the
Plan at any time without the approval of the shareholders of the Company except
as such shareholder approval may be required (a) to satisfy the requirements of
Rule 16b-3 under the Exchange Act, (b) to satisfy applicable requirements of the
Code or (c) to satisfy applicable requirements of any securities exchange on
which are listed any of the Company's equity securities. No such action to amend
or terminate the Plan shall reduce the then existing number of any Participant's
Incentive Options or adversely change the term or conditions thereof without the
Participant's consent. If the Plan is terminated, any unexercised Incentive
Option shall continue to be exercisable in accordance with its terms.

                  Any amendment to this Plan requiring shareholder approval
shall only become effective as of the date it is approved by the affirmative
vote of the holders of three-fourths of the issued and outstanding shares of the
Company.

         16. EFFECTIVE DATE. This Plan was adopted by the Board on January 17,
1995, and shall be effective on such date, provided it is approved by the
affirmative vote of the holders of three-fourths of the issued and outstanding
shares of the Company within twelve (12) months thereafter. Should the
shareholders of the Company fail to approve this Plan within such twelve (12)
months, this Plan and all outstanding Incentive Options shall thereafter be
deemed null and void and shall be of no further force or effect. No Incentive
Options granted under this Plan may be exercised prior to the approval of this
Plan by the shareholders of the Company.

         17. GOVERNING  LAW. This Plan and all actions taken  hereunder 
shall be governed by and construed in accordance with the laws of the State of
Ohio.
