                                 ADMINISTRATION

                  The Plan shall be administered by a Committee appointed by the
Board of Directors. The Committee shall consist of two or more Directors, as the
Board of Directors may determine, provided each member of the Committee shall
qualify to administer the Plan as contemplated by Rule l6b-3 of the Exchange
Act. The Board of Directors may from time to time appoint members of the
Committee in substitution for or in addition to members previously appointed.
Subject to the express provisions of the Plan, the Committee may determine the
individuals to whom and the time or times at which options shall be granted, the
number of Common Shares to be subject to each option, the period of each option,
the vested rights of each Participant in his options (including the vesting
schedule and acceleration of exercise of such options) and other terms and
conditions thereof and shall report its determination to the Board of Directors.
The proper officers of the Company shall carry such determination into effect,
but no action of the Committee or of an officer of the Company shall bind or
become binding upon the Company or create any obligation of the Company
whatsoever unless and until the Company shall have entered into a written and
definitive contract with a proposed Participant in respect of an option for the
purchase of Common Shares and no such contract shall obligate the Company to any
person other than the Participant who is a party to such written contract and to
such persons, if any, as shall be expressly named or provided for in such
written contract. The Committee is authorized to construe and interpret the
Plan, to promulgate, amend and rescind rules and regulations relating to the
implementation of the Plan and to make all other determinations necessary or
advisable for the administration of the Plan. The Committee may designate
persons other than members of the Committee to carry out its responsibilities
under such conditions and limitations as it may prescribe, except that the
Committee may not delegate its authority with regard to selection for,
participation of and the granting of options to persons subject to Section 16(a)
and 16(b) of the Exchange Act. Any determination, decision or action of the
Committee in connection with the construction, interpretation, administration,
or application of the Plan shall be final, conclusive and binding upon all
Participants and any person validly claiming under or through Participants.

                                  ARTICLE FIVE

<PAGE>   4

                  Options may be granted only to those Key Employees as may from
time to time be designated by the Committee. Neither the provisions of the Plan
nor its adoption by the Board of Directors shall be deemed to give any person a
contractual or other right to receive an option under the Plan.

                                   ARTICLE SIX
                                  OPTION PRICE

                  The purchase price pursuant to which Common Shares may be
purchased under each option granted hereunder shall be fixed by the Committee,
but such purchase price shall in no event be less than one hundred percent
(100%) of the Fair Market Value of the Common Shares on the date on which the
option is granted.

                                  ARTICLE SEVEN
                                 TERM OF OPTION

                  The term of each option shall be fixed by the Committee, but
in no event shall any option permit the purchase of Common Shares thereunder
after the tenth (10th) anniversary of the date on which the option is granted.

                                  ARTICLE EIGHT
                               EXERCISE OF OPTION

                  Subject to the provisions of the written option agreement
pursuant to which it is granted, an option may be exercised by giving to the
Company notice in writing (in such form as may from time to time be specified by
the Committee) stating the number of Common Shares subject to the option in
respect of which it is being exercised, accompanied by a check or cash in full
payment of all Common Shares in respect of which the option is being exercised.
Each such notice of exercise of an option shall be delivered to the Chief
Financial Officer of the Company. The Company shall have a reasonable time after
receipt of any such notice in which to make delivery of share certificates for
the Common Shares in respect of which an option is exercised.


                                  ARTICLE NINE
                             TERMINATION OF SERVICE

<PAGE>   5

                  In case a Participant shall cease to be a Key Employee for any
reason, within ninety (90) days next succeeding such termination, but not later
than ten (10) years from the date of grant of the option, the Participant (or
the executor or administrator of his estate) may exercise such option rights as
he then has under this Plan. Options not exercised within the period set forth
in the preceding sentence shall thereupon expire and shall not be exercisable
thereafter.

                                   ARTICLE TEN
                          NON-TRANSFERABILITY OF OPTION

                  No option granted under this Plan shall be transferable
otherwise than by will or the laws of descent and distribution and an option may
not be exercised during the lifetime of a Participant except by him or by his
guardian or legal representative.

                                 ARTICLE ELEVEN
                                   ADJUSTMENTS

                  In the event of any change in the outstanding Common Shares by
stock dividend, stock split, stock combination, reclassification,
recapitalization, merger, reorganization or other change in the Common Shares,
the Committee, upon the advice of accountants and counsel for the Company, shall
determine appropriate adjustments, if any, to be made in the number of Common
Shares and the prices per share in respect of Common Shares subject to
outstanding options and the number of Common Shares then reserved for options
which may thereafter be granted.

                                 ARTICLE TWELVE
                      AMENDMENT AND TERMINATION OF THE PLAN

                  The Company, by action of the Board of Directors, reserves the
right to amend, modify or terminate this Plan at any time, except that the
Company may not, without shareholder approval, increase the total number of
Common Shares subject to options under this Plan (except increases attributable
to the adjustments authorized in Article Eleven hereof), materially increase the
benefits or materially modify the requirements as to eligibility.

                                ARTICLE THIRTEEN
                           RESTRICTIONS AND COMPLIANCE
                              WITH SECURITIES LAWS

                                       51
<PAGE>   6

                  Anything contained in the Plan or elsewhere to the contrary
notwithstanding:

                  (l) No option granted under the Plan shall be exercisable for
the purchase of any Common Shares subject thereto except for:

                             (A) Common Shares subject thereto which at the time
of such exercise and purchase are registered under the Securities Act or which,
upon the completion of such exercise, would be issued in a transaction exempt
from registration under the Securities Act; and

                             (B) Common Shares subject thereto which at the time
of such exercise and purchase are exempt or are the subject matter of an exempt
transaction, are registered by description, by coordination, or by
qualification, or at such time are the subject matter of a transaction which has
been registered by description, all in accordance with Chapter 1707 of the Ohio
Revised Code, as amended; and

                             (C) Common Shares subject thereto in respect of
which the laws of any state applicable to such exercise and purchase have been
satisfied.

                  (2) If Common Shares subject to an option are sold and
transferred upon the exercise thereof to a person who (at the time of such
exercise or thereafter) controls, is controlled by or is under common control
with the Company, or are sold and transferred in reliance upon an exemption
claimed in respect of the securities Act, then upon such sale and transfer:

                             (A) such Common Shares shall not be transferable by
the holder thereof, and neither the Company nor its transfer agent or registrar,
if any, shall be required to register or otherwise to give effect to any
transfer thereof and may prevent any such transfer, unless the Company shall
have received an opinion from its counsel to the effect that any such transfer
would not violate the Securities Act and the applicable laws of any state; and

                             (B) the Company shall cause each share certificate
evidencing such Common Shares to bear a legend reflecting applicable
restrictions on the transfer thereof and may use the following or any other
appropriate legend for that purpose:

         SHARES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE
         SECURITIES ACT OF 1933 (THE "ACT") OR ANY STATE SECURITIES LAWS, ARE
         RESTRICTED SECURITIES WITHIN THE MEANING OF RULE 144 PROMULGATED UNDER
         THE ACT AND MAY NOT BE SOLD, TRANSFERRED, PLEDGED, HYPOTHECATED OR
         OTHERWISE ENCUMBERED OR DISTRIBUTED EXCEPT PURSUANT TO (1) AN EFFECTIVE
         REGISTRATION STATEMENT REGISTERING THE SHARES UNDER THE ACT OR ANY
         APPLICABLE STATE SECURITIES LAWS, IF REQUIRED OR (2) UNTIL THE COMPANY
         HAS RECEIVED AN OPINION FROM ITS COUNSEL TO THE EFFECT


                                       52
<PAGE>   7

         THAT SUCH TRANSFER DOES NOT VIOLATE THE ACT AND THE APPLICABLE
         SECURITIES LAWS OF ANY STATE.

                  (3) Nothing contained in the Plan or elsewhere shall be
construed to require the Company to take any action whatsoever to make
exercisable any option granted under the Plan or to make transferable any Common
Shares issued upon the exercise of any such option.

                                ARTICLE FOURTEEN
                                 TAX WITHHOLDING

                  Any person exercising an option shall be required to pay to
the Company the amount of any taxes the Company is required by law to withhold
with respect to the exercise of such option. Such payment shall be due on the
date the Company is required by law to withhold such taxes. In the event that
such payment is not made when due, the Company shall have the right to deduct,
to the extent permitted by law, from any payment of any kind (but only as
permitted by Rule l6b-3 of the Exchange Act for persons subject to Section 16 of
the Exchange Act) otherwise due to such person from the Company all or part of
the amount required to be withheld.
