the Company and to materially increase shareholder value by providing for the
acquisition of an ownership interest in the Company by Employees and Eligible

special efforts the successful conduct of the Company's operations is largely
dependent.

               [e]       The procedures through which an Option may be
               exercised;

               [f]       The circumstances under which the Company may cancel an
               Option or reacquire any Option and Stock acquired through
               exercise of an Option; and

               [g]       Any other terms and conditions the Committee believes
               appropriate and necessary to implement the intent of this Plan.

          [2]  The Committee may establish different terms and conditions:

               [a]       For different types of Awards;

               [b]       For different Participants receiving the same type of
               Award; and

               [c]       For the same Participant for each Award the Participant
               may receive, whether or not those Awards are granted at different
               times.

          This information (and other information affecting the Award) will be
          compiled in the Notice of Stock Option Grant and the Stock Option
          Agreement, whichever is appropriate, and given to each Participant at
          the time an Award is made.

3.02      NOTICE OF STOCK OPTION GRANT AND STOCK OPTION AGREEMENT. No Option
will be deemed to have been awarded until and if each prospective Participant
returns a signed copy of the Notice of Stock Option Grant and Stock Option
Agreement to the Committee.

                               4.00 ADMINISTRATION

The Committee is responsible for administering the Plan and has all powers
appropriate and necessary to that purpose. Consistent with the Plan's purpose,
the Committee may adopt, amend and rescind rules and regulations relating to the
Plan, to the extent appropriate to protect the Company's interests and to make
all other decisions (including, without limitation, whether a Participant has
incurred a Disability) necessary or advisable for the administration and
interpretation of the Plan. Any action by the Committee will be final, binding
and conclusive for all purposes and upon all persons.

                           5.00 STOCK SUBJECT TO PLAN

5.01      NUMBER OF SHARES. Subject to Section 5.03, the number of shares of
Stock subject to Awards under the Plan may not be larger than 75,000 and no
Participant may receive, in any single year, Options to purchase more than 5,000
shares of Stock. For this purpose, any Award that is cancelled (as described in
Treas. Reg. Section 1.162-27(e)(2)(vi)(B)] will continue to be counted against
the maximum number of shares of Stock for which Awards may be granted to an
Employee under the Plan. The shares of Stock to be delivered under the Plan may
consist, in

                                      - 7 -

cancelled, terminated or otherwise settled without the issuance of any Stock
will again be available for Awards under the Plan.

5.03      ADJUSTMENT IN CAPITALIZATION. If, after the Effective Date, there is a
Stock dividend or Stock split, recapitalization (including payment of an
extraordinary dividend), merger, consolidation, combination, spin-off,
distribution of assets to shareholders, exchange of shares, or other similar
corporate change affecting Stock subject to an Award, the aggregate number of
shares of Stock available for Awards under Section 5.01 or subject to
outstanding Awards and the respective prices and/or limitations applicable to
outstanding Awards will be appropriately adjusted by the Committee, whose
determination shall be conclusive.

                                  6.00 OPTIONS

6.01      GRANT OF OPTIONS. The Committee may grant Options to Participants at
any time during the term of this Plan. Options may be either [1 ] Incentive
Stock Options or [2] Nonstatutory Stock Options. Each Option will be evidenced
by a Stock Option Agreement specifying the type of Option granted, the exercise
price, the duration of the Option, the number of shares of Stock to which the
Option pertains and any other terms and conditions not inconsistent with the
Plan that the Committee believes advisable.

6.02      OPTION PRICE. Options will have an exercise price that is not less
than the Fair Market Value of the Stock on the date the Option is granted.
However, any Incentive Stock Option granted to a Participant who owns [as
defined in Code Section 424(d)] Stock possessing more than 10 percent of the
total combined voting power of all classes of Stock will have an exercise price
that is at least 110 percent of the Fair Market Value of the affected Stock on
the date the Option is granted.

6.03      EXERCISE OF OPTIONS.

          [1]  Options awarded to a Participant under Section 6.01 may be
          exercised at the times and subject to the restrictions and conditions
          (including a vesting schedule) that the Committee; at the time the
          Option is granted, may specify in the Stock Option Agreement. However,
          unless the Committee specifies otherwise in the Stock Option
          Agreement:

               [a]       No Participant will be credited with vesting service
               for any period after his or her relationship with the Company
               ends;

               [b]       No Option may be exercised more than 10 years after the
               date on which it is granted; and

               [c]       No Incentive Stock Option granted to a Participant who
               owns [as defined in Code Section 424(d)] Stock possessing more
               than 10 percent of total combined voting

                                      - 8 -
<Page>

               power of all classes of Stock maybe exercised more than 5 years
               after the date it is granted;

          [2]  An Option may not be exercised for a fraction of a share;

          [31  The Committee may prohibit a Participant from exercising Options
          for fewer than the minimum number of shares specified by the Committee
          in the Stock Option Agreement but only if that prohibition does not
          prevent a Participant from acquiring the full number of shares of
          Stock for which Options are then exercisable;

          [4]  An Option is treated as having been exercised when written notice
          of the exercise has been given to the Company in accordance with the
          terms of the Stock Option Agreement by the Participant and the Company
          has received full payment for the shares of Stock with respect to
          which the Option is exercised; and

          [5]  Regardless of the vesting schedule given above, all Options will
          be fully exercisable by the beneficiary of a deceased Participant,
          subject to the limits described in Section 7.01 [3].

6.04      INCENTIVE STOCK OPTIONS. Notwithstanding anything in the Plan to the
contrary:

          [1]  No provision of this Plan relating to Incentive Stock Options
          will be interpreted, amended or altered, nor will any discretion or
          authority granted under the Plan be exercised, in a manner that is
          inconsistent with Code Section 422 or, without the consent of any
          affected Participant, to cause any Incentive Stock Option previously
          granted to fail to qualify for the federal income tax treatment
          afforded under Code Section 421;

          [2]  The aggregate Fair Market Value of the Stock (determined as of
          the time an Incentive Stock Option is granted) with respect to which
          Incentive Stock Options are exercisable for the first time by any
          Participant during any calendar year (under all option plans of the
          Company and all Subsidiaries of the Company) will not exceed $100,000;
          and

          [3]  No Incentive Stock Option will be granted to any Participant who
          is not an Employee.

                  7.00 TERMINATION OF RELATIONSHIP AND BUY OUT
                               DURING RELATIONSHIP

7.01      EXERCISE PERIOD. Regardless of the term of the Option prescribed in
Section 6.03, a Participant whose relationship with the Company and all of its
Subsidiaries is severed for any reason may exercise any outstanding Options that
are then exercisable under the terms of Section 6.03 and the Stock Option
Agreement for the period specified in the Stock Option Agreement. However, this
period may be no longer than:

          [1]  90 days after the relationship is severed for any reason other
          than Disability; or

          [2]  12 months after the relationship severs because of Disability.

                                      - 9 -
<Page>

7.02      RIGHT OF FIRST REFUSAL.

          [1]  Unless the Committee specifies otherwise in the Stock Option
          Agreement, all Options must reserve to the Company the right of first
          refusal to repurchase any Stock acquired by a Participant or a
          beneficiary through the exercise of Options.

          [2]  This right of first refusal will survive the Participant's
          relationship with the Company and its Subsidiaries.

          [3]  A Participant, former Participant or beneficiary must notify the
          Company, in writing, of any intent to sell any shares of Stock
          acquired through the exercise of Options. To be effective, this notice
          must specify the number of shares to be sold, the intended purchaser,
          the proposed date of the sale and the proposed purchase price. The
          Company then will have six months from the date it receives the
          completed notice to exercise its right to purchase from the
          Participant, former Participant or beneficiary any or all of the
          shares of Stock described in this notice at the Stock's then current
          Fair Market Value. If the Company elects not to purchase the affected
          shares of Stock (or does not respond within the six-month period
          described in the preceding sentence), the right of first refusal will
          lapse and the Participant, former Participant or beneficiary may sell
          the Stock but only under the terms specified and to the person
          described in the notice given to the Committee under this subsection.

          [4]  If the identity of the other party or any of the terms described
          in notice described in Section 7.02[3] change, the Participant, former
          Participant or beneficiary must give another written notice to the
          Company containing the information described in Section 7.02[3] and
          the Company will have an additional six months to decide whether or
          not to exercise its Right of First Refusal under this section. This
          same procedure must be followed with respect to any additional changes
          in the identity of the proposed purchase or the terms of the sale.

7.03      REPURCHASE OPTION. Unless the Committee specifies otherwise in the
Stock Option Agreement, all Options will reserve to the Company a repurchase
option exercisable when:

          [1]  A Participant who is an Employee terminates employment with the
          Company and all Subsidiaries for any reason (including death or
          Disability) without becoming an Eligible Director;

          [2]  Any Participant (whether or not an Employee) exercises any Option
          after terminating his or her relationship with the Company and all
          Subsidiaries and while he or she is not an Eligible Director; and

          [3]  A beneficiary of any deceased Participant exercises any Option
          after the Participant's death.

The price paid for Stock repurchased under this section will be Fair Market
Value at the time of the repurchase, payable in cash or cash equivalents. The
Company will complete any repurchase under this section as soon as
administratively possible after the date it notifies the former Participant or
beneficiary of its intention to exercise its repurchase option under this
section.

7.04      BUY OUT OF OPTION GRANTS. At any time after an Option becomes
exercisable, the Committee may elect, in its sole discretion and without the
consent of the Participant, to cancel the Option and pay to the Participant the
excess of the Fair Market Value of the Stock subject to the cancelled Option
over the Option price at the date the Committee provides written notice ("Buy
Out Notice") of its intention to exercise the right reserved in this section.
The Company will complete any buy out made under this section as soon as
administratively possible after the date of the Buy Out Notice. At the
Committee's option, payment of the buy out amount may be made in cash, in whole
shares of Stock or partly in cash and partly in Stock. The number of whole
shares of Stock, if any, included in the buy out amount will be determined by
dividing the amount of the payment to be made in Stock by the Fair Market Value
of a share of Stock as of the date of. the Buy Out Notice.

in Control occurs, all outstanding and exercisable Options will become fully
vested and each Option will be cancelled as of the date of the Change in Control
in exchange for a payment in cash equal to the difference between [1] the
Stock's Fair Market Value (disregarding the effect of the Right of First Refusal
and Repurchase Options described in Sections 7.02 and 7.03 and the Buy Out
provision described in Section 7.04) and [2] the Option price defined in Section
6.02.

acceleration under Section 8.01, cash settlement or other payment will occur
with respect to any Award or any class of Awards if:

          [1]  The Committee reasonably decides in good faith before the Change
          in Control that the Award or Awards will be honored or assumed by the
          new controlling entity or person, or that new rights will be
          substituted ("Alternative Award") by the new . controlling person or
          entity immediately after the Change in Control; and

          [2]  The Alternative Award:

               [a]       Is based on stock .which is, or within 60 days after
               the Change in Control will be, traded on an established
               securities market;

               [b]       Provides each affected Participant with rights and
               entitlements substantially equivalent to or better than the
               rights, terms and conditions of the affected Award, including an
               identical or better exercise or vesting schedule and identical or
               better timing and methods of payment;

               [e]       Has substantially the same economic value as the
               affected Award (determined at the time of the Change in Control);
               and

               [d]       Provides that, if the Participant's relationship with
               the Company and all Subsidiaries is completely severed
               involuntarily (and, if the Participant is an Employee, is
               constructively terminated) within 12 months after the Change in
               Control, any conditions on a Participant's rights under, or any
               restrictions on

                                     - 11 -

               transfer or exercisability applicable to, the Alternative Award
               will be waived or will lapse.

          Participant who is an Employee following:

               [a]       A permanent reduction in the Employee's title, duties,
               responsibilities or status, as compared to either [i] his or her
               title, duties, responsibilities or status immediately before a
               Change in Control; or [ii] any enhanced or increased title,
               duties, responsibilities or status occurring after the Change in
               Control;

               [b]       The permanent assignment to the Employee of duties
               inconsistent with [i] the Employee's office on the date of the
               Change in Control, [ii] any enhanced or increased duties
               occurring after the Change in Control or [iii] any more senior
               office to which he or she is promoted after the Change in
               Control;

               [c]       A 15 percent (or larger) reduction of the annualized
               base salary rate or total annualized salary rate (including
               bonuses, employee benefits and fringe benefits) the Employee was
               receiving from the Company and Subsidiaries immediately before
               the Change in Control or any increased annualized base salary
               rate or total annualized salary rate he or she receives from the
               Company and Subsidiaries after the Change in Control; or

               [d]       A requirement that the Employee relocate his or her
               principal office or worksite (or the indefinite assignment of the
               Employee) to a location more than 50 miles distant from [i] the
               principal office or worksite to which he or she was permanently
               assigned immediately before the Change in Control or [ii] any
               location to which the Employee is permanently assigned, with his
               or her consent, after the Change in Control.

          Any comparison of a Participant's duties, responsibilities or status
          under this section will be based on those that are permanently
          assigned to the Participant and not on temporarily assigned duties,
          responsibilities or status.

8.03      OPTIONS GRANTED WITHIN SIX MONTHS OF A CHANGE IN CONTROL. Any Option
that was granted within six months before the date on which a Change in Control
occurs and which is held by a person subject to the reporting requirements of
Act Section 16(a) may be cashed out under Section 8.01 only if the Company's
counsel concludes that that cash out will not subject the Participant to
liability under Act Section 16(b).

          9.00 AMENDMENT, MODIFICATION AND TERMINATION OF PLAN

The Board or the Committee may terminate, suspend or amend the Plan at any time.
However:

          [1]  No Plan amendment may cause any Committee member to lose his or
          her status as a "disinterested person" as defined in Rule 16b-3 under
          the Act with respect to any employee benefit plan of the Company or
          cause the Plan to fail to satisfy the requirements of Rule 16b-3;

          Participant except:

               [a]       An amendment to comply with the provisions of any
               applicable law, including the Act and the Code; and

               [b]       Any amendment intended to preserve the status of any
               Incentive Stock Option or the status of the Plan under Code

               defined in Code Section 162(m)(4)(C);

          [4]  Any amendment, termination or suspension may be made without the
          approval of the shareholders of the Company unless shareholder
          approval is required:

               Act;

               [b]       To satisfy applicable requirements of the Act and the
               Code; or

               [c]       To satisfy applicable requirements of any securities
               exchange on which any of the Company's equity securities are
               listed.

                               10.00 MISCELLANEOUS

10.01.    NONTRANSFERABILITY OF AWARDS. Awards granted under the Plan may not be
sold, transferred, pledged, assigned or otherwise alienated or hypothecated,
other than by will or by the laws of descent and distribution. All rights with
respect to Awards granted to a Participant under the Plan may be exercised
during his or her lifetime only by such Participant and after death only by the
Participant's beneficiary as provided in Sections 7.01 and 10.02.

10.02     BENEFICIARY DESIGNATION. Each Participant may from time to time name
any beneficiary or beneficiaries (who may be named contingently or successively)
to whom any benefit under the Plan is to be paid or by whom any right under the
Plan is to be exercised in case of the Participant's death. Each designation
will revoke all earlier designations made by the same Participant, must be in a
form prescribed by the Committee and attached to the Stock Option Agreement and
will be effective only when filed in writing with the Committee. In the absence
of an effective beneficiary designation, the Participant's beneficiary will be
his or her surviving spouse, if any, or otherwise his or her estate.

10.03     NO GUARANTEE OF EMPLOYMENT OR PARTICIPATION. Nothing in the Plan will
interfere with or limit in any way the right of the Company or any Subsidiary to
terminate any Participant's employment at any time or to confer upon any
Participant any right to continue as an Employee or Eligible Director. No
Employee or Eligible Director has any right to be selected as a Participant or
to receive any Awards. Nothing in the Plan confers on an Eligible Director a
right to continue to serve on the Board or to be nominated for reelection to the
Board.

                                     - 13 -

10.04     TAX WITHHOLDING. The Company will withhold from other amounts owed to
the Participant, or require a Participant to remit to the Company, an amount
sufficient to satisfy federal, state and local withholding tax requirements on
any Award, exercise or cancellation of an Option or purchase of Stock and the
Company may defer payment of cash or issuance of Stock until these requirements
are satisfied. The Committee may, in its discretion, permit a Participant to
elect, subject to conditions the Committee establishes, to reimburse the Company
for this withholding obligation through one or more of the following methods:

          [1]  By having shares of Stock otherwise issuable under the Plan
          withheld by the Company (but only to the extent of the minimum amount
          that must be withheld to comply with applicable state, federal and
          local income; employment and wage tax laws);

          [2]  By delivering to the Company previously acquired shares of Stock;

          [3]  By remitting cash to the Company; or

          [4]  By remitting a personal check immediately payable to the Company.

10.05     INDEMNIFICATION. Each person who is or was a member of the Committee
or of the Board will be indemnified and held harmless by the Company against and
from any loss, cost, liability or expense that may be imposed upon or reasonably
incurred by him or her in connection with or resulting from any, claim, action,
suit or proceeding to which he or she may be made a party or in which he or she
may be involved by reason of any action taken or failure to act under the Plan
and against and from any and all amounts paid by him or her in settlement
thereof, with the Company's approval; or paid by him or her in. satisfaction of
any judgment in any such action, suit or proceeding against him or her, provided
he or she gives the Company an opportunity, at its own expense, to handle and
defend the same before he or she undertakes to handle and defend it in his or
her own behalf. The foregoing right of indemnification is not exclusive and is
independent of any other rights of indemnification to which such persons may be
entitled under the Company's Articles of Incorporation or Code of Regulations,
by contract, as a matter of law, or otherwise.

10.06     NO LIMITATION ON COMPENSATION. Nothing in the Plan is to be construed
to limit the right of the Company to establish other plans or to pay
compensation to its employees or directors, in cash or property, in a manner
which is not expressly authorized under the Plan.

10.07     REQUIREMENTS OF LAW. The grant of Awards and the issuance of shares of
Stock will be subject to all applicable laws, rules and regulations and to all
required approvals of any governmental agencies or national securities
exchanges. Also, no Stock will be issued under the Plan unless the Company is
satisfied that that issuance will comply with applicable federal and state
securities laws. Certificates for Stock delivered under the Plan may be subject
to any stock transfer orders and other restrictions that the Committee believes
to be advisable under the rules, regulations and other requirements of the
Securities and Exchange Commission; any stock exchange upon which the Stock is
then listed or traded; the NASDAQ National Market or any applicable federal or
state securities law. The Committee may cause a legend or legends to be placed
on any such certificates to make appropriate reference to such restrictions.

                                     - 14 -

10.08     TERM OF PLAN. The Plan will be effective upon its adoption by the
Committee, subject to approval by the Board and approval by the affirmative vote
of the holders of a majority of the shares of voting stock present in person or
represented by proxy at the first Annual Meeting of Shareholders occurring after
the Board approves the Plan. The Plan will continue in effect, unless sooner
terminated pursuant to Section 9.00, until the tenth anniversary of the date on
which it is adopted by the Board or approval by the Company's shareholders,
whichever is earliest.

10.09     GOVERNING LAW. The Plan, and all agreements hereunder, will be
construed in accordance with and governed by the laws (other than laws governing
conflicts of laws) of the State of Ohio.

10.10     NO IMPACT ON BENEFITS. Plan Awards are incentives designed to promote
the purposes described in Section 1.00. Also, Awards are not compensation for
purposes of calculating an Employee's rights under any employee benefit plan.

                         Section 1.162-27(e)(3) and any rulings issued under
                         that regulation.

          2.   ARTICLE 2.00 DEFINITIONS is amended to insert a new Section 2.22
               thereunder:

                         more forms of Restricted Stock Agreements approved by
                         the Board. Copies of the Restricted Stock Agreements

          3.   Article 5.00 Stock Subject to Plan is hereby amended by adding
               the following sentence to Section 5.01 Number of Shares:

               "In addition to the number of shares set forth above, which
               relate solely to shares available under the Company's Stock
               Option Agreements, an additional 75,000 shares of Stock shall be
               reserved for issuance under such Restricted Stock Agreements as

               Stock being subject to adjustment under the provisions of Section
               5.03 herein."

          IN WITNESS WHEREOF, the undersigned, duly authorized by the Board of
Directors of the Company, has executed this First Amendment effective as at
