**FOR
      VALUE RECEIVED,** the
      undersigned ("Borrower"), promises to pay to the order of **GREENFIELD
      COMMERCIAL CREDIT, L.L.C.** ,
      a
      Michigan limited liability company (the "Lender"), at its office at 300 East
      Long Lake Road, Suite 180, Bloomfield Hills, Michigan 48304, or at such other
      place as Lender may designate in writing, the principal sum of Five Million
      and
      00/100 Dollars ($5,000,000.00), or such lesser sum as shall have been advanced
      by Lender to Borrower pursuant to that certain Third Amendment To Loan and
      Security Agreement dated as of this date, between Borrower and Lender (which,
      together with all amendments and modifications thereof, is hereinafter referred
      to as the "Loan Agreement"), plus interest as hereinafter provided, in lawful
      money of the United States of America, in accordance with the terms
      hereof.




The
      unpaid principal balance of this Second Amended And Restated Revolving Credit
      Loan Note ("Note") shall bear interest computed upon the basis of a year of
      360
      days for the actual number of days elapsed in a month, at a rate of interest
      (the "Effective Rate") which is equal to four and one-half (4.5) percentage
      points above the prime rate (hereafter defined), as such rate shall vary from
      time to time, upwards and downwards, and each such Prime Rate change shall
      cause
      an identical change in the Effective Rate to occur effective immediately. "Prime
      Rate" means that rate of interest published from day to day in the WALL STREET
      JOURNAL in its Money Rates column as the "Prime Rate." Should such publication
      not continue to publish the Prime Rate or a substitute rate, then Lender will
      select a comparable announced rate.




Interest
      on all principal amounts advanced by Lender from time to time and unpaid by
      Borrower shall be paid on the first (1st) day of the month following execution
      of this Note, and on the same day of each month thereafter until the Due Date,
      upon which date the entire unpaid principal balance of this Note, together
      with
      all accrued and unpaid interest, shall be due and payable in full. Borrower
      shall pay to Lender a late charge of five percent (5%) of any monthly payment
      not received by Lender within ten (10) calendar days after said payment is
      due,
      which late charge shall be payable on the next monthly payment date or on
      demand. In addition to the foregoing, Borrower shall pay to Lender on the first
      day of each month with respect to the prior calendar month or portion thereof,
      the amount, if any, necessary to pay the fees as set forth in the Loan
      Agreement.




Advances
      of principal, repayment, and readvances may be made under this Note from time
      to
      time, upon the terms set forth in the Loan Agreement and said Loan Agreement
      is
      incorporated herein by reference. Mandatory repayments of principal before
      the
      Due Date shall be made by Borrower to Lender pursuant to the Loan
      Agreement.




All
      advances made hereunder shall be charged to a loan account in Borrower's name
      on
      Lender's books, and Lender shall debit to such account the amount of each
      advance made to, and credit to such account the amount of each repayment made
      by
      Borrower. Lender shall furnish Borrower with a monthly statement of Borrower's
      loan account, which statement shall be deemed to be correct, accepted by, and
      binding upon Borrower, unless Lender receives a written statement of exceptions
      from Borrower within thirty (30) days after such statement has been furnished.
      Borrower expressly assumes all risks of loss or delay in the delivery of any
      payments made by mail, and no course of conduct or dealing shall affect
      Borrower's assumption of these risks.




Upon
      the
      Due Date, which Borrower acknowledges may be upon demand, Lender, without prior
      notice to Borrower, may declare the entire unpaid principal balance of this
      Note
      and all accrued interest, together with all other indebtedness of Borrower
      to
      Lender, to be immediately due and payable. Upon the occurrence of any Default
      specified on the Loan Agreement or upon demand, the unpaid principal balance
      of
      this Note shall bear interest at a rate which is four percent (4%) greater
      than
      the Effective Rate otherwise applicable. After Default or Demand, Lender may
      apply its own indebtedness or liability to Borrower to any indebtedness due
      under this Note. Borrower agrees to pay all of the Lender's costs incurred
      in
      the collection of this Note as provided in the Loan Agreement.







Acceptance
      by Lender of any payment in an amount less than the amount then due shall be
      deemed an acceptance on account only. Upon any Default, neither the failure
      of
      the Lender promptly to exercise its right to declare the outstanding principal
      and accrued unpaid interest hereunder to be immediately due and payable, nor
      the
      failure of the Lender to demand strict performance of any other obligation
      of
      the Borrower or any other person who may be liable hereunder, shall constitute
      a
      waiver of any such rights, nor a waiver of such rights in connection with any
      future default on the part of the Borrower or any other person who may be liable
      hereunder.




Borrower
      acknowledges that no Default is necessary for Lender to make
      Demand.




Borrower
      and all endorsees, sureties and guarantors hereof hereby jointly and severally
      waive presentment for payment, demand, notice of non-payment, notice of protest
      or protest of this Note, and Lender diligence in collection or bringing suit,
      and do hereby consent to any and all extensions of time, renewals, waivers
      or
      modifications as may be granted by Lender with respect to payment or any other
      provisions of this Note, and to the release of any collateral or any part
      thereof, with or without substitution. The liability of Borrower under this
      Note
      shall be absolute and unconditional, without regard to the liability of any
      other party. This Note and all rights and obligations hereunder shall be
      governed by the laws of the State of Michigan.




In
      no
      event whatsoever shall the interest rate and other charges charged hereunder
      exceed the highest rate permissible under any law which a court of competent
      jurisdiction shall, in the final determination, deem applicable hereto. In
      the
      event that a court determines that Lender has received interest or other charges
      hereunder in excess of the highest rate applicable hereto, Lender shall either,
      in its sole discretion, promptly apply such amounts to the principal due
      hereunder or refund such amount to Borrower and the provisions herein shall
      be
      deemed amended to provide for such permissible rate.




This
      Note
      is issued pursuant to the terms of the Loan Agreement and is secured by the
      Collateral, as defined in the Loan Agreement. All of the terms, covenants and
      conditions of the Loan Agreement are hereby made a part of this Note and are
      hereby incorporated by reference.
