          WHEREAS, as a condition to the consummation of the transactions

the Merger Agreement, Executive and the Company desire to enter into an
agreement providing for the employment of Executive by the Company and for
certain arrangements upon the termination of Executive's relationship with the
Company under the terms and conditions of this Agreement;

          NOW, THEREFORE, in consideration of the mutual covenants and
agreements contained herein, the Company and Executive hereby agree as follows:

          1.   EMPLOYMENT.  Beginning on the date hereof and continuing for a
period of three (3) years thereafter, unless terminated earlier pursuant to
Section 8 of this Agreement, the Company shall employ Executive as President of
the Company, and Executive hereby accepts such employment and agrees to perform
all duties consistent with such position that are assigned to him from time to
time by the Board of Directors of the Company or its designee (the "Board"). 
The term of this Agreement automatically shall be extended for additional one-

                                     -1-



year periods unless either party notifies the other party in writing at least
thirty (30) days prior to the end of the then current term that it does not wish
to extend the term of this Agreement.  The period of time during which Executive
is employed by the Company is referred to herein as the "Employment Period." 
During the Employment Period, Executive shall devote his full time and best
efforts to the business and welfare of the Company.  Such duties shall be
rendered primarily at the Company's facility in Ottawa Lake, Michigan, and the
surrounding area, and shall include such regular travel as is necessary in
connection with the performance of his duties hereunder.

          2.   SALARY AND BONUSES.

               (a)  BASE SALARY.  During the Employment Period, the Company will
pay Executive for his services a base salary at the annual rate of $125,000.00,
which salary shall be payable in accordance with the Company's standard payroll
practices.  The Board, in its sole and absolute discretion, may increase such
base salary based on an annual review of Executive's performance.

               (b)  ANNUAL BONUS.  During the Employment Period, Executive shall
be entitled to participate in an annual bonus plan under which Executive shall
receive, with respect to each fiscal year or partial fiscal year of the Company
during the Employment Period, such percentage of the Annual Bonus Pool (as
defined below), if any, as the Board shall determine with respect to such fiscal
year or partial fiscal year.  The Annual Bonus Pool, if any, shall be
distributed to such key employees of the Company (including Executive) and in
such amounts as the Board may determine in its sole discretion after giving due
consideration to the recommendations of Executive.  Distributions from the
Annual Bonus Pool, if any, shall be payable by March 1 of the following year. 
An Annual Bonus Pool shall be established with respect to any fiscal year of the
Company in which the Company achieves the performance goals developed by the
Board in its sole discretion with respect to such fiscal year after consultation
with Executive, which performance goals may be based on the Company's return on
its net assets, earnings before interest and taxes or other factors determined
by the Board.  For purposes of this Agreement, the term "Annual Bonus Pool"
shall mean an amount equal to ten percent (10%) of the aggregate earnings (if
any) of the Northcoast Companies (as defined in Section 2.1.2 of the Stock
Purchase Agreement), before interest, before taxes, and before any amortization
of goodwill arising from the transactions contemplated by the Asset Purchase
Agreement, the Stock Purchase Agreement or the Merger Agreement, all as
reflected on the statements of income of the Northcoast Companies in accordance
with generally accepted accounting principles, and including as an expense for
the purpose of such calculation the amount of the Annual Bonus Pool and all
sales commissions payable by the Northcoast Companies.

               (c)  SIGNING BONUS.  On the day after the Closing Date, the 
Company will cause Northcoast/America to discharge Executive's existing 
indebtedness to Northcoast/America in the amount of $105,099.89, or will pay 
such amount to Northcoast/America on Executive's behalf (the "Signing 
Bonus"). Executive and the 

                                     -2-



Company will each treat such cancellation or satisfaction of indebtedness, 
for income tax purposes, as being $105,099.89 of compensation to Executive 
for services performed, and will prepare their respective tax returns 
accordingly.  On or before the first payroll date after the Closing Date, 
Executive will pay the Company all federal, state and local tax withholdings 
due as a result of the Signing Bonus.

          3.   BENEFITS.  During the Employment Period, Executive shall be 
entitled: (a) to participate in any group medical, short-term and long-term 
disability, and life insurance benefit plans and any 401(k) or other 
retirement savings or pension plans which are maintained or established for 
employees of the Company generally (but subject to the eligibility and 
vesting provisions thereof); (b) to the use of one (1) automobile which may 
be selected by Executive but shall be subject to the approval of the Board 
(which automobile may be owned or leased by the Company), and the payment or 
reimbursement by the Company for the expenses of related insurance, 
maintenance and repair, and gas and oil (but only to the extent the 
automobile is used for business purposes); (c) to four (4) weeks' paid 
vacation per year; (d) to reimbursement of monthly dues paid by Executive for 
one country club or dining club approved by the Board and up to two travel 
clubs approved by the Board; and (e) to be reimbursed for reasonable 
business, promotional, travel and entertainment expenses actually incurred by 
Executive on behalf of the Company in the performance of his duties during 
the Employment Period, if and to the extent such expenses are approved by the 
Board.  Executive agrees that he shall at all times keep, maintain and 
furnish to the Company adequate records and documentation of the benefits 
provided under paragraphs (b), (d) and (e) of this Section 3 in accordance 
with Company policies as in effect from time to time, and to the extent 
required by the United States Internal Revenue Code and the regulations 
thereunder to ensure the availability to the Company of all deductions and 
credits attributable to such benefits.  Executive acknowledges that 
reimbursed club dues and non-business usage of Company-provided automobiles 
will be treated for income tax purposes as compensation to Executive for 
services performed.

          4.   NONCOMPETITION.  Executive agrees that during the Employment
Period and for a period of one (1) year thereafter, he will not directly or
indirectly operate or perform any advisory or consulting services for, invest in
(other than publicly traded stock constituting less than 5% of the equity of a
publicly held corporation), or otherwise operate or become associated in any
capacity with, any corporation, partnership, organization, proprietorship or
other business entity or association which sells or performs services then in
competition with the Company in the Business anywhere within the United States
of America; PROVIDED, HOWEVER, that if the Company terminates Executive's
employment without Cause (as defined in Section 8(e)) and the Company desires to
have this noncompetition covenant remain in effect with respect to any period of
time following the fifth anniversary of the date of this Agreement, then the
Company shall pay to Executive the sum of Fifty Thousand Dollars ($50,000) as
additional consideration for this covenant for the twelve-month period following
the later to occur of the fifth anniversary of the date of this Agreement and
the effective date of Executive's termination of employment, payable quarterly
in arrears.

                                     -3-



          5.   NONDISCLOSURE.  Executive agrees at all times to hold as secret
and confidential (unless disclosure is required by the Company or would be in
furtherance of Executive's employment with the Company or is required pursuant
to court order, subpoena in a governmental proceeding, arbitration or pursuant
to other process or requirement of law) any and all knowledge, information,
developments, manufacturing and trade secrets, know-how and confidences of the
Company or its business of which he has knowledge as of the date hereof, or of
which he may acquire knowledge during the Employment Period, to the extent such
matters have not previously been made public, are not thereafter made public or
do not otherwise become available to Executive from a third party who is not, to
Executive's best knowledge, bound by any confidentiality agreement with the
Company ("Confidential Information").  The phrase "made public" as used in this
Agreement shall apply to matters within the domain of (a) the general public or
(b) the Company's industry.  Executive agrees not to use such knowledge for his
own benefit or for the benefit of others or, except as provided above, disclose
any of such Confidential Information without the prior written consent of the
Board, which consent shall make express reference to this Agreement.

          6.   NONINTERFERENCE.  Executive agrees that during the Employment
Period and for a period of one (1) year thereafter, he will not, without the
prior written consent of the Board, directly or indirectly solicit, induce or
attempt to solicit or induce any employee, agent, or other representative or
associate of the Company to terminate its relationship with the Company or in
any way interfere with such a relationship or a relationship between the Company
and any of its suppliers or distributors.

          7.   DISCLOSURE OF PROPRIETARY INTELLECTUAL PROPERTY.  Executive
agrees that he will promptly disclose to the Company any and all improvements,
discoveries, ideas or inventions composing proprietary intellectual property
which may be material to the operations and business of the Company (the
"Improvements") which Improvements are made or conceived by Executive, acting
alone or in conjunction with others, either (a) during the Employment Period, or
(b) within two (2) years after the Employment Period, if such Improvement
results from or was suggested by such employment or in any way relates to the
Business.  Executive shall not disclose any such Improvement to any person
except the Company and shall use all reasonable efforts to provide the Company
written disclosure of such Improvements.  Each such Improvement shall be the
sole and exclusive property of and is hereby assigned to the Company.  Executive
agrees that, at the request of the Company, Executive will execute such
applications, statements, assignments or other documents, furnish such
information and data and take all such other action (including without
limitation the giving of testimony) as the Company may from time to time
reasonably request in order to obtain for the Company a registration or patent
in the United States or any foreign country covering or pertaining to any such
Improvement.

          9.   REMEDY FOR CERTAIN BREACHES.  Executive acknowledges that in
consideration for the covenants set forth in Sections 4 through 7 hereof, the
Company has granted to Executive the employment, salary and benefits described

for the fair and reasonable protec-

                                     -6-



tion of the Company. Executive further acknowledges and agrees that a breach 
of any of such covenants will result in irreparable and continuing damage to 
the Company for which there will be no adequate remedy at law, and Executive 
agrees that in the event of any such breach the Company and its successors 
and assigns shall be entitled to injunctive relief to restrain such breach by 
Executive and to such other and further relief (including damages) as is 
proper under the circumstances.

          10.  REFORMATION OF AGREEMENT; SEVERABILITY.  The parties intend this
Agreement to be enforced as written.  However, in the event that any provision
of this Agreement is held by a court of competent jurisdiction to be invalid or
unenforceable as against public policy or otherwise, Executive and the Company
hereby authorize and instruct such court to exercise its discretion in reforming
such provision to the end that Executive shall be subject to such restrictions
and obligations as are reasonable under the circumstances and enforceable by the
Company.  In the event that any term of this Agreement is found to be void or
unenforceable to any extent for any reason, it is the agreed upon intent of the
parties that all remaining terms of this Agreement shall remain in full force
and effect to the maximum extent permitted by law and this Agreement shall be
enforceable as if such void or unenforceable term had never been a part hereof.

Agreement shall be in writing and shall either be delivered in person or by
United States mail.  Notices mailed to Executive shall be addressed to him at

          12.  ASSIGNMENT.  No rights of any kind under this Agreement shall,
without the written consent of the Company, be transferable to or assignable by
Executive, or be subject to alienation, encumbrance, garnishment, attachment,
execution or levy of any kind, voluntary or involuntary.  This Agreement shall
be binding upon and shall inure to the benefit of the Company and its successors
and assigns.

          13.  ENTIRE AGREEMENT.  This Agreement contains the entire agreement
between the parties with respect to the subject matter hereof, and there shall
be no implied terms in addition to the express terms contained herein. 
Concurrently herewith, in the Stock Purchase Agreement, in the Asset Purchase
Agreement and in the Merger Agreement, Executive has made certain nondisclosure,
noncompetition and noninterference covenants to and for the benefit of the
Company and its affiliates, which covenants by Executive are similar to those

and the Company that such separate covenants in the Stock Purchase Agreement,

employment hereunder, and that such 

                                     -7-



separate covenants shall be separately enforceable in accordance with the 
respective terms thereof notwithstanding any provision hereof.

          14.  AMENDMENTS, WAIVERS, ETC.  This Agreement may not be changed
orally, but only by an agreement, in writing, signed by Executive and an officer
of the Company specifically designated by the Board to execute such amendment.

specifically referring to this Agreement, executed by the party waiving
compliance.  The failure of the Company at any time or from time to time to
require performance of any of Executive's obligations under this Agreement shall
in no manner affect the Company's right to enforce any provisions of this
Agreement at a subsequent time; and the waiver by the Company of any right
arising out of any breach shall not be construed as a waiver of any right
arising out of any subsequent breach.  

          15.  CAPTIONS.  The section and paragraph headings used in this
Agreement are intended solely for convenience of reference and shall not be
given effect in construing its provisions.
