administer the Plan on behalf of the Board, subject to such terms and
conditions as the Board may prescribe, provided that each Committee member
shall be a Non-Employee Director.  Members of the Committee shall serve for
such period of time as the Board may determine.  Members of the Board or the
Committee who are eligible for Options or have been granted Options may vote on
any matters affecting the administration of the Plan or any Options pursuant to
the Plan, except that no such member shall act upon an Option to himself or
herself, but any such member may be counted in determining the existence of a
quorum at any meeting of the Board or Committee during which action is taken
with respect to an Option to himself or herself.

Committee and appoint additional members thereto (provided such new members are
Non-Employee Directors), remove members (with or without cause) and appoint new
members in substitution therefor, fill vacancies however caused, or remove all
members of the Committee and thereafter directly administer the Plan.

any, to be covered by each such award granted hereunder;

                          c.  to determine the terms and conditions, not 
inconsistent with the terms of the Plan, of any Option granted hereunder,
including, but not limited to, the share price and any restriction or
limitation, any vesting provisions, or any vesting acceleration or forfeiture
waiver regarding any Stock Option and/or the shares of Stock relating thereto,
or the length of the period following termination of employment of any
Participant during which any Stock Option may be exercised, based on such
factors as the Committee shall determine, in its sole discretion;

                          e.  to determine whether and under what circumstances
a Stock Option may be exercised without a payment of cash under Section 5(j).

                 The Committee shall have the authority to adopt, alter and 
repeal such administrative rules, guidelines and practices governing the Plan as
it shall, from time to time, deem advisable; to interpret the terms and
provisions of the Plan and any Option issued under the Plan (and any agreements
relating thereto); to amend the terms of any agreement relating to any Option
issued under the Plan; and to otherwise supervise the administration of the
Plan.  The Committee may correct any defect, supply any omission or reconcile
any inconsistency in the Plan or in any Option granted in the manner and to the
extent it shall deem necessary to carry out the intent of the Plan.

                 All decisions made by the Committee pursuant to the provisions
of the Plan shall be final and binding on all persons, including the
Corporation and Participants.  No member of the Committee shall be liable for
any good faith determination, act or failure to act in connection with the Plan
or any award made under the Plan.

                 SECTION 3.  STOCK SUBJECT TO THE PLAN.

            a.  Stock Subject to the Plan.  The stock to be subject to Options
under the Plan shall be shares of Stock and may be either authorized and
unissued shares of Stock or shares of Stock held in the treasury of the
Corporation.  The maximum number of shares of Stock that may be the subject of
Options under the Plan is 1,317,178 and the Corporation shall reserve for the
purposes of the Plan, out of its authorized and unissued shares of Stock or out
of shares of Stock held in its treasury, or partly out of each, such number of
shares. Notwithstanding the foregoing, no individual shall receive Options for
more than an aggregate of  925,000 shares of Stock authorized for grant under
the Plan.
        
            b.  Effect of the Expiration or Termination of Options.  If and to
the extent that an Option granted under the Plan expires, terminates or is
canceled or forfeited for any reason without having been exercised in full, the
shares of Stock associated with the expired,
        


                                     -4-
   5

terminated, canceled or forfeited portion of the Option shall not become
available for grant under the Plan.

            c. Other Adjustment.  In the event of any merger, reorganization,
consolidation, recapitalization, Stock distribution or dividend, Stock split or
combination, or other change in corporate structure affecting the Stock, such
substitution or adjustment shall be made in the number and option price of
securities subject to outstanding Options granted under the Plan, as may be
determined to be appropriate by the Committee in its sole discretion, provided
that the number of securities subject to any Option shall always be a whole
number.

        SECTION 4.  ELIGIBILITY.  Officers and other employees of the 
Corporation or its Subsidiaries are eligible to be granted Options under the 
Plan.

        SECTION 5.  STOCK OPTIONS.  Stock Options granted under the Plan shall
be Non-Qualified Stock Options.

                Options granted under the Plan shall be subject to the 
following terms and conditions and shall contain such additional terms and
conditions, not inconsistent with the terms of the Plan, as the Committee shall
deem appropriate:

                a.  Option Price.  The exercise price per share of Stock 
purchasable under a Non-Qualified Stock Option shall be $1.88.

                b.  Option Term.  The term of each Stock Option shall be fixed 
by the Committee, but no Stock Option shall be exercisable more than ten years
after the date the Option is granted.  No Option may be exercised by any person
after expiration of the term of the Option.
        
                c.  Exercisability.  Subject to the termination provisions set
forth in Sections 5(f) through (h), Stock Options shall vest and be exercisable
only upon satisfaction of the following two conditions:
        
                        (i)  Time.  Subject to Section 5(i), with respect to 
the grant of Options under the Plan, 1/3 of the number of shares subject to such
Option shall vest and be exercisable three (3) years from the date of grant, a
second 1/3 of such shares shall vest and be exercisable four (4) years from the
date of grant, and the final 1/3 of such shares shall vest and be exercisable
five (5) years from the date of grant.
        
                        (ii)  Stock Price.  The Fair Market Value of the Stock
(or the price per share to be paid in the event of a Change of Control, as
determined by the Committee for purposes of this Section 5(c)(ii)) shall have
reached or exceeded the level specified in column (B) below during the time
period set forth in column (A) below, measured from the date of adoption of this
Plan:

         1 to 2 years                      $ 3
         2 to 3 years                      $ 3 7/8
         3 to 4 years                      $ 5
         4 to 5 years                      $ 6 5/8
         5 to 6 years                      $ 8 5/8
         After 6 years                     $11 1/2

        d.  Method of Exercise.  Subject to the exercise provisions under 
Section 5(c) and the termination provisions set forth in Sections 5(f) through
(h), Stock Options may be exercised in whole or in part at any time and from
time to time during the term of the Option, by giving written notice of exercise
to the Corporation specifying the number of shares to be purchased.  Such notice
shall be accompanied by payment in full of the purchase price, either by
certified or bank check, or such other instrument as the Committee may accept. 
As determined by the Committee, in its sole discretion, at or after grant,
payment in full or in part (but only for whole shares) of the exercise price of
a Stock Option may be made in the form of Stock based on the Fair Market Value
of the Stock on the date the Option is exercised.
        
        No shares of Stock shall be issued upon exercise of an Option until full
payment therefor has been made.  A Participant shall not have the right to
dividends and other rights of a shareholder with respect to shares of Stock
subject to the Option until the Participant has given written notice of
exercise, has paid in full for such shares, and, if requested, has given the
representation described in Section 8(a) hereof.

        e.  Non-transferability of Options.  No Stock Option shall be 
transferable by the Participant otherwise than by will or by the laws of descent
and distribution or pursuant to a qualified domestic relations order, as defined
in the Code or Title I of the Employee Retirement Income Security Act of 1974,
and all Stock Options shall be exercisable, during the Participant's lifetime,
only by the Participant or, in the event of his Disability, by his personal
representative.
        
        f.  Termination by Reason of Death.  Subject to Section 5(i), if a
Participant's service with the Corporation or any Subsidiary terminates by
reason of death, any Stock Option held by such Participant may thereafter be
exercised, to the extent then exercisable, by the legal representative of the
estate or by the legatee of the Participant under the will of the Participant,
for a period expiring (i) at such time as may be specified by the Committee at
the time of grant, or (ii) if not specified by the Committee, then one year
from the date of death, or (iii) if sooner than the applicable period specified
under (i) or (ii) above, then upon the expiration of the stated term of such
Stock Option.

        g.    Termination by Reason of Disability. Subject to Section 5(i), if a
Participant's service with the Corporation or any Subsidiary terminates by
reason of Disability, any Stock Option held by such Participant may thereafter
be exercised by the Participant or his personal representative, to the extent
it was exercisable at the time of termination, for a period expiring (i) at
such time as may be specified by the Committee at the time of grant, or (ii) if
not


                                     -6-
   7

specified by the Committee, then six months from the date of termination of
service, or (iii) if sooner than the applicable period specified under (i) or
(ii) above, then upon the expiration of the stated term of such Stock Option;
provided, however, that if the Participant dies within such period, any
unexercised Stock Option held by such Participant shall, at the sole discretion
of the Committee, thereafter be exercisable to the extent to which it was
exercisable at the time of death for a period of six months from the date of
such death (or such other period as may be specified by the Committee) or until
the expiration of the stated term of such Stock Option, whichever period is
shorter.

        h.  Other Termination.  If a Participant's service with the 
Corporation or any Subsidiary terminates for any reason other than death,
Disability, termination for Cause or voluntary termination, any Stock Option
held by such Participant may thereafter be exercised by the Participant, to the
extent it was exercisable at the time of such termination, for a period expiring
(i) thirty (30) days from the date of termination of service, or (ii) if sooner
than the applicable period specified under (i) above, then upon the expiration
of the stated term of such Stock Option.  If a Participant's service terminates
for Cause or pursuant to his voluntary termination, any Stock Option held by
such Participant shall be deemed to have expired and become non-exercisable on
the day prior to the Participant's termination from service.
        
        i.  Change of Control. All Stock Options outstanding as of the date of
a Change of Control shall be deemed to have satisfied the "Time" condition for
exercisability of Options set forth in Section 5(c)(i).
        
        j.  Cashless Exercise.  To the extent permitted under the Rules, in 
the sole discretion of the Committee, the Corporation may cooperate in a
"cashless exercise" of an Option.  The cashless exercise shall be effected by
the Participant delivering to the Securities Broker instructions to sell a
sufficient number of shares of Stock to cover the costs and expenses associated
therewith.
        
        SECTION 6.  AMENDMENTS AND TERMINATION.  The Board may amend, alter or
discontinue the Plan at any time and from time to time, but no amendment,
alteration or discontinuation shall be made which would impair the rights of a
Participant with respect to a Stock Option which has been granted under the
Plan, without the Participant's consent, or which, without the approval of the
Corporation's shareholders, would:

        a.  except as expressly provided in the Plan, increase the total 
number of shares of Stock reserved for the purposes of the Plan;

        b.  change the persons or class of persons eligible to participate in 
the Plan; or

        c.  extend the maximum option term under Section 5(b) of the Plan.

        Subject to the above provisions, the Board shall have broad authority 
to amend the Plan to take into account changes in applicable tax laws and
accounting rules, as well as other developments.  Notwithstanding the
foregoing, no amendment to the Plan may be made by the
        

                                     -7-
   8

Board without the approval of the Corporation's shareholders if such approval
would be required under the Rules in order to ensure that transactions effected
under the Plan are eligible for the benefit of Rule 16b-3.

        SECTION 7.  UNFUNDED STATUS OF PLAN.  The Plan is intended to 
constitute an "unfunded" plan for incentive and deferred compensation.  With
respect to any payments not yet made to a Participant or optionee by the
Corporation, nothing contained herein shall give any such Participant or
optionee any rights that are greater than those of a general creditor of the
Corporation.  In its sole discretion, the Committee may authorize the creation
of trusts or other arrangements to meet the obligations created under the Plan
to deliver Stock or payments in lieu of Stock hereunder.
        
        SECTION 8.   GENERAL PROVISIONS.

        a.  The Committee may require each person acquiring Stock under the 
Plan to represent to and agree with the Corporation in writing that the
Participant is acquiring the Stock for investment purposes and without a view to
distribution thereof and as to such other matters as the Committee believes are
appropriate to ensure compliance with applicable Federal and state securities
laws.  The certificate evidencing such award and any securities issued pursuant
thereto may include any legend which the Committee deems appropriate to reflect
any restrictions on transfer and compliance with securities laws.
        
        All certificates for shares of Stock or other securities delivered 
under the Plan shall be subject to such stock-transfer orders and other
restrictions as the Committee may deem advisable under the rules, regulations,
and other requirements of the Securities Act of 1933, as amended, the Exchange
Act, any stock exchange upon which the Stock is then listed, and any other
applicable Federal or state securities laws, and the Committee may cause a
legend or legends to be put on any such certificates to make appropriate
reference to such restrictions.
        
        b.  Nothing contained in the Plan shall prevent the Board from 
adopting other or additional compensation arrangements, subject to shareholder
approval if such approval is required; and such arrangements may be either
generally applicable or applicable only in specific cases.
        
        c.  The adoption of the Plan shall not confer upon any employee of the
Corporation or a Subsidiary any right to continued employment with the
Corporation or such Subsidiary, nor shall it interfere in any way with the
right of the Corporation or such Subsidiary to terminate the employment of any
of its employees at any time.

        d.  No later than the date as of which an amount first becomes 
includable in the gross income of the Participant for Federal income tax
purposes with respect to any Option under the Plan, the Participant shall pay to
the Corporation, or make arrangements satisfactory to the Committee regarding
the payment, of any Federal, state or local taxes of any kind required by law to
be withheld with respect to such amount.  Unless otherwise determined by the
Committee, the minimum required withholding obligations may be settled with
Stock, including Stock that is
        



                                     -8-
   9

part of the award that gives rise to the withholding requirement.  The
obligations of the Corporation under the Plan shall be conditional on such
payment or arrangements and the Corporation shall, to the extent permitted by
law, have the right to deduct any such taxes from any payment of any kind
otherwise due to the Participant.

        e.  The Plan and all Options granted and actions taken thereunder 
shall be governed by and construed in accordance with the laws of the State of
Michigan.

        SECTION 9. EFFECTIVE DATE OF PLAN.  This Plan shall become effective 
on the date that it is adopted by the Board.  The Board may grant Options
hereunder prior to approval of the Plan or any material amendments thereto by
the holders of a majority of the Corporation's outstanding voting stock. 
Notwithstanding the foregoing, no Option granted under this Plan may be
exercised prior to the satisfaction of the following condition: the
Corporation's adoption of a Charter Amendment increasing the Corporation's
authorized shares of common stock to 20 million.
        
        SECTION 10. TERM OF PLAN.  No Stock Option shall be granted pursuant 
to the Plan on or after the tenth (10th) anniversary of the date of shareholder
approval of the Plan, but awards granted prior to such tenth (10th) anniversary
may extend beyond that date.
