                  "Formula Amount" shall mean, as of the date of any
         determination thereof, the sum of:

                                                               November 24, 2003

         FOR VALUE RECEIVED, on or before the Termination Date, RIVIERA TOOL
COMPANY, a Michigan corporation ("Company"), promises to pay to the order of

($10,000,000) as may from time to time have been advanced and then be
outstanding hereunder pursuant to the Line of Credit and Term Loan Agreement
dated December 23, 2002, made by and between Company and Bank (herein called

         Capitalized terms used herein and not defined to the contrary have
meanings given them in the Agreement.

         Interest on the unpaid balance of Loans from time to time outstanding,
shall be payable to the extent then accrued, at the Applicable Interest Rate
determined under, as and when provided in the Agreement. Interest shall be
computed on the basis of a 360 day year and assessed for the actual number of
days elapsed, and in such computation effect shall be given to any change in the
Prime-based Rate or the Applicable Margin on the date of any change in the Prime
Rate or Applicable Margin.

         From and after the occurrence of any Event of Default, the indebtedness
outstanding hereunder shall bear interest as provided in Section 2.12 of the
Agreement, which interest shall be payable on demand.

         This Note is a note under which advances, repayments and re-advances
may be made from time to time, subject to the terms and conditions of the
Agreement. This Note evidences borrowing under, is subject to, may be prepaid in
accordance with, and may be matured under the terms of the Agreement, to which
reference is hereby made. This Note is secured by the Collateral described in

conditions under which this Note may be accelerated.

         The undersigned and all accommodation parties, guarantors and indorsers
(i) waive presentment, demand, protest and notice of dishonor, (ii) agree that
no extension or indulgence to the undersigned or release or non-enforcement of
any security, whether with or without notice, shall affect the obligations of
any accommodation party, guarantor or indorser, and (iii) agree to reimburse the
holder of this Note for any and all costs and expenses incurred in collecting or
attempting to collect any and all principal and interest under this Note
(including, but not limited to, court costs and reasonable attorney fees,
whether such costs and expenses are incurred in formal or informal collection
actions, federal bankruptcy proceedings, appellate proceedings, probate
proceedings, or otherwise). Any transferees of, or endorser, guarantor or surety
paying this Note in full shall succeed to all rights of Bank, and Bank shall be
under no further responsibility for the exercise thereof or the loan evidenced
hereby. Nothing herein shall limit any right granted Bank by other instrument or
by law.

         COMPANY AND THE BANK ACKNOWLEDGE THAT THE RIGHT TO TRIAL BY JURY IS A
CONSTITUTIONAL ONE, BUT THAT IT MAY BE WAIVED, AND, AFTER CONSULTING WITH
COUNSEL OF THEIR CHOICE, KNOWINGLY AND VOLUNTARILY, AND FOR THEIR MUTUAL
BENEFIT, WAIVE ANY RIGHT TO TRIAL BY JURY IN THE EVENT OF LITIGATION REGARDING
THE PERFORMANCE OR ENFORCEMENT OF, OR IN ANY WAY RELATED HERETO.

         All capitalized terms used but not defined herein shall have the
meanings ascribed to them in the Agreement.

         This Note amends and restates, but does not extinguish the indebtedness
evidenced by, the Line of Credit Note dated December 23, 2002, in the original
principal amount of $7,500,000.
