SECTION 2 - WARRANTIES AND REPRESENTATIONS

           To induce the Subordinated Lender to enter into this Agreement, the
Borrower represents and warrants to the Subordinated Lender that the following
statements are true, correct and accurate both before and after giving effect to
the transactions contemplated by the Senior Loan Documents and the Subordinated
Loan Documents:

           2.1 The Borrower is a corporation duly organized, validly existing,
and in good standing under the laws of the State of Michigan. The Borrower is
duly qualified and authorized to do business, and is in good standing as a
foreign corporation, in all jurisdictions in which the failure to be so
qualified or authorized to do business would have a Material Adverse Effect.

           2.2 The Borrower has all requisite corporate power and authority and
all necessary licenses and permits to own and operate its properties and to
carry on its business as now conducted and as it contemplates that business to
be conducted in the future. The Borrower is in compliance with all laws, rules,
and regulations, the non-compliance with which would have a Material Adverse
Effect.

           2.3 All financial statements of the Borrower that have been delivered
to the Subordinated Lender have been prepared in accordance with GAAP, subject
to normal year-end adjustments and footnotes for interim, unaudited statements,
and present fairly the financial position of the Borrower as of the dates
indicated, and the results of its operations for the periods indicated. No
changes having a Material Adverse Effect have occurred since the date of the
most recent of such financial statements. Except as expressly set forth in such
financial statements and the liabilities set forth in the Senior Loan Documents
and the Subordinated Loan Documents, the Borrower has

                                       2
<PAGE>

no material contingent liability or liability for taxes, long-term lease or
unusual forward or long-term commitment; provided, however, that the footnotes
contained in the audited financial statements provide information necessary to
complete a review of the Borrower's entire liabilities, contingent and
non-contingent, that is not contained in interim statements.

           2.4 Neither this Agreement nor the financial statements referred to
in Section 2.3 above, nor any other written statement furnished by or on behalf
of the Borrower to the Senior Lender in connection with the Senior Loans or to
the Subordinated Lender in connection with the Subordinated Loan, contains any
untrue statement of a material fact or omits a material fact necessary to make
the statements contained therein or herein not misleading. To Borrower's
Knowledge, there is no fact that the Borrower has not disclosed to the
Subordinated Lender in writing that has, or in the future is likely to have, a
Material Adverse Effect.

           2.5 There are no proceedings pending, or to Borrower's Knowledge
threatened, before any court, governmental authority, or arbitration board or
tribunal, against or affecting the Borrower, the outcome of which may reasonably
be expected to have a Material Adverse Effect. The Borrower is not in default
with respect to any order, judgment, or decree of any court, governmental
authority, or arbitration board or tribunal.

           2.6 All of the outstanding capital stock of the Borrower is validly
issued, fully paid and nonassessable.

           2.7 The Borrower has good and marketable title to all of the assets
that it purports to own, including the assets described in the financial
statements referred to in Section 2.3 hereof, free and clear from all liens,
encumbrances, security interests, claims, charges, and restrictions whatever,
except Permitted Liens. The Borrower owns no real property. All real property
leased by the Borrower is suitable for its current intended purposes and is
served by such utilities and has such access to public roadways and other
transportation structures and systems as are necessary for the proper and
efficient use, operation and maintenance thereof. The Borrower enjoys peaceful
and undisturbed possession under all real property leases to which it is a
party, and all such leases are valid and subsisting and in full force and effect
and no default (nor any event which, with notice or lapse of time or both, would
constitute such a default) has occurred or is continuing under any of such
leases on the part of the Borrower or, to Borrower's Knowledge, on the part of
the landlord. There have been no renewals or extensions of or supplements,
modifications or amendments to any of such leases except as previously disclosed
in writing to the Subordinated Lender.

           2.8 The Borrower owns and controls all of the patents, trademarks,
service marks, trade names, copyrights, licenses, and rights necessary for the
present and planned future conduct of its business, without any conflict with
the right of any other person, firm, or corporation.

           2.9 The Borrower has full corporate power and authority to execute,
deliver, and perform the Senior Loan Documents and the Subordinated Loan
Documents; the execution, delivery, and performance of the Subordinated Loan
Documents by the Borrower have been duly authorized by appropriate corporate
action of the Borrower and will not violate the provisions of the articles of
incorporation or bylaws of the Borrower or of any law, rule, judgment, order,
agreement, or instrument to which the Borrower is a party or by which it is
bound, or to which any of its assets are subject, nor do the same require any
approval or consent of any public authority or other third party; and the
Subordinated Loan Documents have been duly executed and delivered by the
Borrower, and are the valid and binding obligations of the Borrower, enforceable
in accordance with their terms.

           2.10 All tax returns required to be filed by the Borrower in any
jurisdiction have been filed, and all taxes, assessments, fees, and other
governmental charges upon the Borrower or upon its assets, income, or franchises
have been paid before the time that those taxes became delinquent. The Borrower
knows of no proposed additional tax assessment against it.

           2.11 The Borrower has no investments in the securities of any other
corporation or business entity. The Borrower does not intend to carry or
purchase any "margin security" within the meaning of Regulation U of the Board
of Governors of the Federal Reserve System, 12 C.F.R. Chapter II.

           2.14 The execution, delivery and performance by the Borrower of each
Subordinated Loan Document and the consummation of the transactions contemplated
hereby or related hereto do not and will not (a) conflict with, result in a
breach of or constitute (with due notice or lapse of time or both) a default
under any contractual obligation of the Borrower, (b) result in or require the
creation or imposition of any lien (other than liens in favor of the
Subordinated Lender) upon any of its properties or assets, or (c) require any
approval of stockholders that has not been obtained or any approval or consent
of any person under any actual or purported contractual obligation of the
Borrower.

                                       3
<PAGE>

           2.15 The Borrower is not in default in the performance, observance or
fulfillment of any of the obligations, covenants or conditions contained in any
actual or purported contractual obligation of the Borrower, and no condition
exists that, with the giving of notice or the lapse of time or both, would
constitute such a default, which default could have a Material Adverse Effect.

SECTION 3 - THE SUBORDINATED LOAN

           3.1 As of the date of this Agreement, the Subordinated Loan is the
only outstanding indebtedness of the Borrower to the Lender. The Subordinated
Loan is evidenced by the Subordinated Note. The Borrower acknowledges that the
Lender has not agreed and is not otherwise committed or required to make any
other loans to the Borrower or to extend credit in any other form to the
Borrower. The Borrower acknowledges that the Subordinated Loan is not a
revolving loan, and that amounts repaid on the Subordinated Loan cannot be
re-borrowed and will not be re-advanced or otherwise made available to the
Borrower. The Subordinated Loan is subject in all respects to the terms and
conditions of this Agreement and the other Subordinated Loan Documents.

SECTION 4 - SECURITY

           4.1 The Subordinated Loan is unsecured.

SECTION 5 - AFFIRMATIVE COVENANTS

           From the date hereof and until the Subordinated Loan has been paid in

           independent certified public accountants satisfactory to the
           Subordinated Lender, containing the Borrower's balance sheet as of
           the end of that year, its related profit and loss, and a statement of
           shareholder's equity for that year, its statement of cash flows for
           that year, together with any management letter prepared by those
           certified public accountants, and such comments and financial details
           as are customarily included in reports of like character and the
           unqualified opinion of the certified public accountants as to the
           fairness of the statements therein, and together with such written
           assurances as the Subordinated Lender may reasonably request from the
           Borrower's independent certified public accountants to confirm the
           Subordinated Lender's entitlement to rely upon such audited financial
           report and accompanying materials;

                      (b) within 30 days after the end of each calendar month,

                      (c) monthly work in process reports, due no later than the
           7th day of each month for the preceding month, the accuracy of which
           is certified to by the Chief Financial Officer of the Borrower; and

                      (d) within 30 days after the end of each fiscal quarter,
           beginning with February 28, 2003, a certificate executed by the Chief
           Financial Officer of the Borrower stating whether all of the
           financial covenants contained in this Agreement are satisfied,
           showing the calculations for making such determinations, and
           otherwise in a form acceptable to Subordinated Lender.

           5.2 Promptly inform the Subordinated Lender of any occurrence that is
an Event of Default or that, with the giving of notice or the lapse of time, or
both, would be an Event of Default and of any other occurrence which has a
Material Adverse Effect; grant to the Subordinated Lender or its representatives
the right to examine its books and records at any reasonable time or times;

such insurance coverages as are customarily maintained by similar businesses);

that insurance and satisfactory evidence of that insurance coverage; and, within
30 days after receipt of a written request from the Subordinated Lender, obtain
any additional insurance that the Subordinated Lender may reasonably request.

           5.4 Pay and discharge, as often as the same may become due and
payable, all taxes, assessments and other governmental monetary obligations, of
whatever nature, that may be levied or assessed against it or any of its
properties, unless and to the extent only that in a jurisdiction where payment
of taxes and assessments is abated during the period of any contest, those taxes
or assessments shall be contested in good faith by appropriate proceedings and
that the Borrower shall have set aside on its books adequate reserves with
respect to those taxes and assessments.

           5.5 Pay and perform at the time such payment or performance is due,

of the other Subordinated Loan Documents, by statute or in law or equity. The

SECTION 8 - MISCELLANEOUS

           8.1 The Borrower shall pay all out-of-pocket expenses incurred by the
Subordinated Lender in connection with making and collecting the Subordinated
Loan and enforcing the Subordinated Loan Documents, including but not limited to
reasonable attorneys' fees relating to (a) the enforcement, or attempted
enforcement, of any provision of any of the Subordinated Loan Documents, (b) the
collection of the Subordinated Loan, and (c) the foreclosure of any security
interests or other liens given with respect thereto. Notwithstanding the
foregoing, the Borrower shall not be obligated to pay more than $5,000 in
attorneys' fees incurred by the Subordinated Lender in

                                       7
<PAGE>

connection with making the Subordinated Loan (as contrasted with collecting the
Subordinated Loan, foreclosing the liens and security interests securing the
Subordinated Loan, and otherwise enforcing or attempting to enforce the
Subordinated Loan Documents, as to which the Borrower shall be obligated to pay
all reasonable attorneys' fees and other costs incurred by the Subordinated
Lender, in addition to reimbursing the Subordinated Lender for reasonable
attorneys' fees, not to exceed $5,000, in connection with making the
Subordinated Loan).

           8.2 Upon the occurrence of an Event of Default, or any event which
with the giving of notice or lapse of time, or both, would constitute an Event
of Default, the Subordinated Lender shall be entitled to set off any
indebtedness from time to time owing to the Borrower by the Subordinated Lender,
including any indebtedness represented by any account maintained with the
Subordinated Lender by the Borrower, against any indebtedness that shall at any
time be due and payable by the Borrower to the Subordinated Lender.

           8.3 Each and every right granted to the Subordinated Lender under
this Agreement or any other Subordinated Loan Document, or allowed by statute or
at law or in equity, shall be cumulative and may be exercised from time to time.
No failure on the part of the Subordinated Lender to exercise, and no delay in
exercising, any right shall operate as a waiver thereof or as a waiver of any
other right. No single or partial exercise by the Subordinated Lender of any
right or remedy shall preclude any other future exercise of it or the exercise
of any other right or remedy. No waiver or indulgence by the Subordinated Lender
of any default shall be effective unless in writing and signed by the
Subordinated Lender, nor shall a waiver on one occasion be construed as a bar to
or waiver of that right on any future occasion. This Agreement may not be
amended except by a writing signed by all the parties hereto.

           8.4 The relationship between the Borrower and the Subordinated Lender
is solely that of borrower and lender. The Subordinated Lender has no fiduciary
responsibilities to the Borrower as a result of this Agreement or any other
Subordinated Loan Document, or the consummation of the transactions contemplated
hereby or thereby. The Subordinated Lender does not undertake any responsibility
to the Borrower to review or inform the Borrower of any matter in connection
with any phase of the Borrower's business or operations. The Borrower shall rely
entirely upon its own judgment with respect to its business, and any review,
inspection, supervision, or information supplied to the Borrower by the
Subordinated Lender is for the protection of the Subordinated Lender and neither
the Borrower nor any third party is entitled to rely thereon.

           8.5 This Agreement is made in the State of Michigan. The validity of
this Agreement, and the validity of the other Subordinated Loan Documents, and
the construction, interpretation and enforcement thereof, and the rights of the
parties thereto, shall be determined under and construed in accordance with the
internal laws of the State of Michigan, without regard to principles of
conflicts of law.

           8.6 Any and all notices or other communications required or permitted
under this Agreement shall be in writing, and shall be served either personally
or by certified United States mail with postage thereon full prepaid addressed

<PAGE>

           8.7 This Agreement shall be binding upon and shall inure to the
benefit of the Borrower and the Subordinated Lender and their respective
successors and assigns; provided, however, the Borrower may not assign,
transfer, hypothecate or otherwise dispose of its rights hereunder or in
connection herewith or any interest herein (voluntarily, by operation of law, as
security, by gift or otherwise) without the prior written consent of the
Subordinated Lender, which consent may be withheld in the sole discretion of the
Subordinated Lender. There are no third party beneficiaries of this Agreement.
The Subordinated Lender may assign, negotiate, pledge or otherwise hypothecate
all or any portion of this Agreement, or grant participations herein and in the
Subordinated Loan Documents, or in any of its rights or security hereunder or
thereunder, including, without limitation, the instruments securing the
Borrower's obligations hereunder, provided, however, that no such assignment,
negotiation, pledge or other hypothecation by the Subordinated Lender will
relieve the Subordinated Lender of its obligation under this Agreement. In
connection with any assignment or participation, the Subordinated Lender may
disclose to the proposed assignee or participant any information that the
Borrower is required to deliver to the Subordinated Lender pursuant to this
Agreement.

           8.8 Upon any change in generally accepted accounting principles that,
if reflected in the financial statements or covenants required or established in
this Agreement, would have a material effect on such statements or covenants,
either party may request that the parties enter into negotiations to amend the
financial covenants or other terms of this Agreement so as to equitably reflect
such changes with the desired result that the criteria for evaluating the
Borrower's financial condition shall be the same after such changes as if the
changes had not been made.

           8.9 Should any part, term or provision of this Agreement or any of
the other Subordinated Loan Documents be determined by the courts to be illegal,
unenforceable or in conflict with any law of the State of Michigan, federal law
or any other applicable law, the validity and enforceability of the remaining
portions or provisions of such document(s) shall not be affected thereby.

           8.10 The Borrower shall execute any and all additional or
supplemental documentation, and provide such further assistance and assurances
as the Subordinated Lender may reasonably require, to give full effect to the
terms, conditions and intentions of this Agreement and the other Subordinated
Loan Documents.

           8.11 Time is of the essence with respect to all provisions of this
Agreement.

           8.12 The headings in this Agreement have been inserted for
convenience only and shall not affect the meaning or interpretation of this
Agreement.

           8.13 This Agreement may be executed in one or more counterparts, each
of which shall be considered an original and all of which shall constitute the
same instrument.

           8.14 This Agreement contains the entire agreement of the parties
hereto with respect to the subject matter hereof. The parties hereto shall not
be bound by any other different, additional or further agreements or
understandings except as consented to in writing by them.

           8.15 The Recitals are incorporated into and form a part of this
Agreement.

           8.16 The Subordinated Lender and the Borrower, after consulting or
having had the opportunity to consult with counsel, knowingly, voluntarily and
intentionally waive any right either of them may have to a trial by jury in any
litigation based upon or arising out of this Agreement or any other Subordinated
Loan Document, or any of the transactions contemplated by this Agreement or the
other Subordinated Loan Documents, or any course of conduct, dealing, statements
(whether oral or written), or actions of either of them. Neither the
Subordinated Lender nor the Borrower shall seek to consolidate, by counterclaim
or otherwise, any such action in which a jury trial has been waived with any
other action in which a jury trial cannot be or has not been waived. These
provisions shall not be deemed to have been modified in any respect or
relinquished by either the Subordinated Lender or Borrower except by a written
instrument executed by both of them.

           THE INDEBTEDNESS EVIDENCED BY THIS PROMISSORY NOTE IS UNSECURED.
           PAYMENT OF THE INDEBTEDNESS EVIDENCED BY THIS PROMISSORY NOTE IS
           SUBORDINATE TO PAYMENT OF THE UNDERSIGNED BORROWER'S INDEBTEDNESS TO
           COMERICA BANK TO THE EXTENT SET FORTH IN AN INTERCREDITOR AGREEMENT
           DATED DECEMBER 23, 2002, BETWEEN COMERICA BANK AND FIFTH THIRD BANK.
           PAYMENT OF THE INDEBTEDNESS EVIDENCED BY THIS PROMISSORY NOTE IS ALSO
           SUBORDINATE TO PAYMENT OF THE UNDERSIGNED BORROWER'S INDEBTEDNESS TO
           CERTAIN GUARANTORS TO THE EXTENT SET FORTH IN A SUBORDINATION
           AGREEMENT DATED DECEMBER 23, 2002, BETWEEN FIFTH THIRD BANK AND SUCH
           GUARANTORS.

                     SUBORDINATED UNSECURED PROMISSORY NOTE

$1,414,985.80                                                  December 23, 2002

           For value received, RIVIERA TOOL COMPANY, a Michigan corporation
(BORROWER), promises to pay to the order of FIFTH THIRD BANK, a Michigan banking
corporation f/k/a Old Kent Bank (the SUBORDINATED LENDER), the principal sum of
ONE MILLION FOUR HUNDRED FOURTEEN THOUSAND NINE HUNDRED EIGHTY-FIVE AND 80/100
DOLLARS ($1,414,985.80), plus interest on the outstanding principal indebtedness
evidenced by this Promissory Note from time to time at the rate of eleven
percent (11.0%) per year, except during default. Interest shall be computed on
the basis of a 360-day year and the actual number of days elapsed during the
period for which the computation is made.

           Following maturity or acceleration of the indebtedness evidenced by
this Promissory Note, the interest rate on the entire principal balance of this
Promissory Note shall be 200 basis points higher than the interest rate
otherwise in effect. In addition, if any payment required by this Promissory
Note is not made within 15 days of its due date, the Borrower shall be liable
for a late payment charge in an amount equal to five percent (5%) of the monthly
payment due, except that in no event shall the late payment charge exceed $2,000
and in no event shall a late payment charge be assessed as to any payment that
falls due during a Blockage Period, as defined in the Intercreditor Agreement
dated December 23, 2002 (the INTERCREDITOR AGREEMENT), between the Subordinated
Lender and Comerica Bank (the SENIOR LENDER). The late payment charge shall
apply individually to all payments past due (except as provided in the preceding
sentence), without proration. All such default interest and late payment
charges, if any, shall be paid upon demand by the holder of this Promissory Note
(the HOLDER.)

           The indebtedness evidenced by this Promissory Note, unless sooner
prepaid or accelerated as provided in the Subordinated Loan Agreement dated
December 23, 2002, between the Borrower and the Subordinated Lender (the
SUBORDINATED LOAN AGREEMENT), shall be paid in monthly installments of principal
and interest in the amount of THIRTY-ONE THOUSAND AND 00/100 DOLLARS
($31,000.00) each, except that the final monthly payment shall be an amount
equal to all then unpaid principal and accrued and unpaid interest. Such
payments of principal and interest shall be due and payable on the first (1st)
day of each month, beginning February 1, 2003, and continuing on the same day of
each month thereafter through and including January 1, 2008, when all then
unpaid principal and accrued and unpaid interest shall be due and payable in
full, unless sooner accelerated by the Holder.

           The indebtedness evidenced by this Promissory Note may be prepaid in
whole or in part at any time without premium. Partial prepayments shall be
applied to the payments required by this Promissory Note in the inverse order of
their respective maturities, therefore no partial prepayment shall postpone the
due date of any of the regularly scheduled payments called for by this
Promissory Note or reduce the amount of any such payments.

           All payments under this Promissory Note shall be made in lawful money
of the United States of America to the Subordinate Lender at its principal
office in Grand Rapids, Michigan, or at such other place as the Holder may from
time to time specify.

                                       11
<PAGE>

           Except as otherwise provided in the Intercreditor Agreement, the
Holder shall have the right, upon the occurrence of: (a) a default in making any
payment when due in accordance with this Promissory Note; or (b) a default under
the Subordinated Loan Agreement; or (c) a default under any of the other
Subordinated Loan Documents, provided in each case that such default has not
been cured after notice and within the applicable cure period, to the extent the
Subordinated Loan Agreement requires the giving of notice or provides for a cure
period, to declare all then unpaid indebtedness evidenced by this Promissory
Note to be immediately due and payable in full, and to immediately pursue any
and all other remedies available to the Holder pursuant to this Promissory Note,
any of the other Subordinated Loan Documents, by statute or at law or in equity.
Capitalized terms used but not defined in this Promissory Note shall have the
meanings given them in the Subordinated Loan Agreement.

           Neither the failure of the Holder promptly to exercise its right to
declare the outstanding principal and accrued and unpaid interest and other
charges under this Promissory Note to be immediately due and payable, nor the
failure to exercise any other right or remedy the Holder may have for default,
nor the acceptance by the Holder of late or partial payments, nor the failure of
the Holder to demand strict performance of any obligation of the Borrower under
this Promissory Note, shall constitute a waiver of any such rights while such
default continues, nor a waiver of any such rights in connection with any future
default on the part of the Borrower. Further, acceptance by the Holder of
partial payments following due acceleration of the indebtedness evidenced by
this Promissory Note shall not constitute a waiver by the Holder of the
acceleration of such indebtedness or of any other right or remedy otherwise
available to the Holder in such circumstance.

           The Borrower waives presentment, protest and demand, notice of
protest, demand, dishonor and nonpayment of this Promissory Note.

                                       12
<PAGE>

           The Borrower agrees to pay all costs incurred by the Holder,
including without limitation costs of collection and reasonable attorney's fees,
in case the principal of this Promissory Note or any payment of interest
required by this Promissory Note is not paid when due, or in case it becomes
necessary to protect the security for this Promissory Note, whether suit is
brought or not, or in case of any other default under this Promissory Note.

           Any payment (including prepayments) upon this Promissory Note shall
be applied first to any expenses, charges or fees then due and payable to the
Holder in connection with the indebtedness evidenced by this Promissory Note or
any collateral for such indebtedness, then to any accrued and unpaid interest
under this Promissory Note, and then to the unpaid principal balance.

           In no event shall the Borrower be required to make any payment under
this Promissory Note that would violate any applicable law regulating or
limiting the rate of interest that the Holder may lawfully charge or collect. If
any such payment is made by or for the account of the Borrower, such payment
shall, to the extent it exceeds the maximum payment that the Holder lawfully may
charge or collect, be applied toward reduction of the principal balance of the
indebtedness evidenced by this Promissory Note.

           This Promissory Note shall be governed by and enforced and construed
in accordance with the laws of Michigan. The invalidity, illegality or
unenforceability of any one or more of the provisions of this Promissory Note
shall not affect the validity, legality or enforceability of the remaining
provisions of this Promissory Note, all of which shall remain in full force and
effect.
