                          CENTRUM INDUSTRIES, INC.

                           STOCK OPTION AGREEMENT


        THIS AGREEMENT is made as of this 10th day of June, 1998, by and
between Centrum Industries, Inc., a Delaware corporation ("Centrum") and
_______________________________ ("Director").

        NOW THEREFORE, in consideration of the mutual covenants contained in
this Agreement, the parties hereto agree as follows:

        SECTION 1 - GRANT OF OPTION.  Centrum hereby grants to Director the
right and option to purchase from it, on the following terms and conditions,
all or any part of an aggregate of Ten Thousand (10,000) shares of Centrum's
common stock $.05 par value (the "Shares").  The purchase price for all Shares
shall be Two and 00/00 Dollars ($2.00) per share, exercisable and payable as
hereinafter provided.  This price per share represents the fair market value
for these shares as of this date, as determined by Centrum's Board of
Directors.

        SECTION 2 - EXERCISE OF OPTION; CHANGE OF CONTROL.  The Director may
elect to exercise the option at any time.   Notwithstanding the above, if
Centrum's officers or directors execute a letter of intent (binding or
non-binding) by which Centrum will become a party to a transaction which will
effect a "Change of Control" of Centrum, Director must exercise his/her options
within the thirty (30) day period following the date of notice to Director that
a letter of intent has been entered into, or else the option and all rights
granted by this Agreement, to the extent those rights have not been exercised,
will terminate and become null and void.  No partial exercise of such option
may be for less than one (1) full Share.  For purposes of this Agreement
"Change of Control" shall be effected if (i) Centrum merges with or into or
consolidates with another corporation following the requisite approval of the
shareholders of Centrum of such merger or consolidation and, after giving
effect to such merger or consolidation, less than fifty-one (51%) of the then
outstanding voting securities of the surviving or resulting corporation
represent or were issued in exchange for voting securities of Centrum
outstanding immediately prior to such merger or consolidation; (ii) there is a
sale, lease, exchange or other transfer (in one transaction or a series of
related transactions) of all or substantially all the assets of Centrum
following the requisite approval of the shareholders of Centrum of such
transaction or series of transactions; or (iii) the requisite approval of the
shareholders of Centrum is obtained to approve any plan or proposal for the
liquidation or dissolution of Centrum.  The option shall be exercisable only by
Director during his/her lifetime and only if Director was a director of Centrum
or a Centrum affiliate on the date three (3) months prior to the date of
exercise.  If Director is disabled within the meaning of Section 22(e)(3) of
the Internal Revenue Code of 1986, as amended (the "Code"), the reference to
the three (3) month period above shall be read as one (1) year.  

   2


        SECTION 3 - METHOD OF EXERCISE.  The option granted under this
Agreement shall be exercisable as provided above, upon written notice to
Centrum and the payment in cash to Centrum of the full purchase price of the
Shares which the Director elects to purchase.

        SECTION 4 - TERMINATION OF DIRECTORSHIP.  In the event that a Director
shall cease to serve as a director of Centrum or a Centrum affiliate, whether
voluntarily or involuntarily, for any reason other than death or disability,
all of Director's rights to further exercise his/her option(s) shall expire
three (3) months after the date of termination of the directorship; provided,
however, that no option shall be exercisable after the expiration date set
forth in Section 6.  A leave of absence with the express written consent of
Centrum shall not be considered termination of the directorship for purposes of
this Section 4.

        SECTION 5 - DEATH OR DISABILITY OF DIRECTOR.  In the event of the
death or disability of a Director while a director of Centrum or a Centrum
affiliate, his/her right to purchase Shares may be exercised (to the extent
that Director was entitled to do so at the date of his/her death or disability)
by him/her or, in the case of the death of Director, by his/her personal
representative or by any person or persons who shall have acquired the option
directly from Director by will or by the laws of descent and distribution, at
any time within three (3) months after the date of his/her death or disability;
provided that if Director is disabled as defined in Section 2 of this
Agreement, the three (3) month period referred to above shall be read as one
(1) year.  Notwithstanding anything herein to the contrary, no option shall be
exercisable after the expiration of the term of the option set forth in Section
6.

        SECTION 6 - TERMINATION OF OPTION.  The option and all rights granted
by this Agreement, to the extent those rights have not been exercised will
terminate and become null and void at 5:00 p.m. on June 10, 2008.

        SECTION 7 - SHARES AS INVESTMENT.  By accepting this option, the
Director acknowledges that any and all Shares purchased pursuant to the
exercise of the option under this Agreement shall be acquired for investment
and not for distribution, and upon the delivery of any and all of the Shares
due to the exercise of the option granted hereunder, the Director shall deliver
to Centrum a representation in writing and in a form acceptable to Centrum that
such Shares are being acquired in good faith for investment and not for
distribution.  This Section 7 shall not apply in the event that the Shares have
been registered pursuant to the Securities Act of 1933 and applicable state
securities laws.  

        SECTION 8 - RESTRICTIONS ON SHARES.  It is contemplated that the Shares
issued pursuant to the exercise of the option granted in Section 1 shall be
registered under the federal securities laws and the securities law of any
applicable state.  In the event that the Shares are not so registered and will,
therefore, be deemed restricted,  certain restrictions will be applicable upon
the resale of such security.  In such event, each Share will, upon issuance,
contain a restrictive legend in substantially the following form:  

                                      2
   3


                The common stock represented by this certificate has not been
                registered under the Securities Act of 1933, as amended or
                under the securities laws of any state.  Each holder
                desiring to transfer the common stock must furnish Centrum with
                a written opinion reasonably satisfactory to Centrum in the
                form and substance from counsel reasonably satisfactory to
                Centrum by reason of experience to the effect that the holder
                may transfer the common stock as desired without registration
                under the Securities Act or the securities laws of any state.

This Section 8 shall not apply in the event that the Shares have been
registered pursuant to the Securities Act of 1933 and applicable state
securities laws.  

        SECTION 9 - DILUTION OR OTHER AGREEMENT.  In the event that additional
Shares are issued pursuant to a stock split or a stock dividend, the number of
Shares then covered by each outstanding option granted hereunder shall be
increased proportionately with no increase in the total purchase price of the
Shares then so covered.  If the issued and outstanding Shares are reduced by a
reverse stock split or other combination of Shares, (other than by a
transaction described in Section 2 of this Agreement), the number of Shares
then covered by each outstanding option granted hereunder shall be reduced
proportionately with no reduction in the total price of the Shares then so
covered.  In the event that Centrum should transfer assets to another
corporation and distribute the stock of such other corporation without the
surrender of Shares, and if such distribution is not taxable as a dividend and
no gain or loss is recognized by reason of Section 355 of the Code, or some
similar section, then the total purchase price of the Shares shall be reduced
by an amount which bears the same ratio to the total purchase price then in
effect as the market value of the stock distributed with respect to the Shares
immediately following the distribution, bears to the aggregate of the market
value of such time of a Share and the stock distributed in respect thereof.  No
fractional shares shall be issued, and any fractional Shares resulting from the
computations pursuant to this Section 9, shall be eliminated from the option. 
No adjustment shall be made for cash dividends or the issuance to stockholders
of rights to subscribe for additional Shares or other securities.

        SECTION 10 - RIGHT OF SHAREHOLDER.  The Director shall not have any
rights or privileges of a shareholder of Centrum in respect with the Shares
transferable upon exercise of the option granted under this Agreement, unless
and until certificates representing such Shares shall have been endorsed,
transferred, and delivered and the transferee has caused his/her name to be
entered as the shareholder of record on the books of Centrum.

        SECTION 11 - NON-TRANSFERABILITY.  The option shall not be
transferable and the option may be exercised, during the lifetime of the
Director only by him/her.  Except as specifically provided in this Agreement,
the option may not be assigned, transferred, pledged or hypothecated in any
way, shall not be assignable by operation of 

                                      3
   4

law, including but not limited to a decree in a domestic relations
proceeding, and shall not be subject to execution, attachment or similar
process.  Any attempted assignment, transfer, pledge, hypothecation or other
disposition of the option, and the levy of any execution, attachment, or
similar process upon the option in violation of this Agreement, shall be null
and void and without effect.  Notwithstanding the foregoing, a director who was
nominated for his position on Centrum's Board pursuant to the Equity Holder's
Agreement dated as of February 29, 1996, effective as of March 8, 1996, by and
among First New England Capital Limited Partnership, MorAmerica Capital Corp.,
North Dakota Small Business Investment Company, Centrum, and certain
shareholders of Centrum, may transfer this option to an entity who proposed his
nomination.

        SECTION 12 - AFFILIATE.  As used herein, the term "affiliate" shall
mean any present or any future corporation which would be deemed an affiliate
of Centrum in Rule 12b-2 of the regulations promulgated pursuant to the
Securities Exchange Act of 1934.

        SECTION 13 - NOTICES.  Any notice to be given under the terms of this
Agreement shall be addressed to Centrum in care of its President at 6135 Trust
Drive, Suite 104A, Holland, Ohio 43528 with a copy to John W. Hilbert II, Esq.,
Fuller & Henry P.L.L., One SeaGate, 17th Floor, P. O. Box 2088, Toledo, Ohio
43603 and any notice to be given to Director shall be addressed to him/her at
the address set forth beneath his/her signature below, or at such other address
as either  party may hereafter designate in writing to the other.  Any such
notice shall be deemed duly given when mailed by prepaid regular, registered,
or certified mail.

        SECTION 14 - BINDING EFFECT. This Agreement shall be binding upon
Director and his/her executors administrators, and representatives and assigns,
and upon Centrum and its successors and assigns.

        IN WITNESS WHEREOF, the parties have executed this Agreement on the
date first set forth above.
