                          REVOLVING LINE OF CREDIT NOTE

$3,000,000                                                   Southgate, Michigan
                                                                February 7, 2001

         FOR VALUE RECEIVED, the undersigned promises to pay on demand to the
order of ASC, INC., a Michigan corporation ("Lender"), or order, at its office
located at One Heritage Place, Suite 400, Southgate, Michigan 48195, or at such
other place as the holder hereof may from time to time designate in writing, the
principal sum of $3,000,000, or so much of such sum as has been advanced and is
outstanding, plus accrued but unpaid interest thereon as specified below.

         The undersigned promises to pay plus interest calculated as the sum of
Lender's aggregate cost of borrowing such Principal including, without
limitation, (a) Lender's actual cost or interest incurred with respect to such
Principal and (b) any incremental cost to Lender arising from or caused by such
Principal (the "Note Rate"). Such Note Rate shall apply until demand or
maturity, whether by acceleration or otherwise, and at the rate of 3% per annum
above the Note Rate on overdue principal from the date when due until paid;
provided that the Note Rate may be adjusted to any legal rate including fair
market value upon the mutual agreement of the parties. Notwithstanding the
foregoing, Lender and Borrower hereby agree and acknowledge that the Note Rate
shall equal or exceed the applicable federal rate.

         If any payment is not received by Lender within fifteen days after its
due date, Lender may assess and the undersigned agrees to pay a late fee equal
to five percent of the past due amount. Payment of this late fee in no way
waives any default due to the undersigned's failure to make timely payments on
this Note.

         Principal of and interest on this Line of Credit Note ("Note") is
payable in lawful money of the United States of America. The undersigned agrees
to pay all costs of collection and enforcement of this Note, including
reasonable attorneys' fees and court costs.

         This Note is given in accordance with, and is subject to the terms and
conditions of, a Secured Credit Agreement dated on or about the same date as
this Note, between Lender and the undersigned (as may be amended or restated
from time to time, the "Loan Agreement"). Any capitalized terms used in this
Note but not defined in this Note have the same meanings as in the Loan
Agreement. This Note is secured by, among other collateral, the Collateral
granted Lender under and pursuant to the terms of the Loan Agreement and the
other Loan Documents (as well as in all agreements and documents referred to or
incorporated therein), and all other collateral granted to Lender by the
undersigned at any time to secure any present or future obligation of

any party to Lender. The failure to make any payment when due under this Note or
the occurrence of any event of default under the Loan Agreement or any other
Loan Document is a default under this Note, and in any such events, the holder
of this Note is entitled to accelerate the maturity of the debt evidenced by
this Note and have all rights and remedies afforded by law or available under
the Loan Agreement and the other Loan Documents.

         This Note may be prepaid in whole or in part at anytime without
penalty.

         The undersigned, and all endorsers and guarantors, hereby severally
waive valuation and appraisement, presentment, protest and demand, notice of
protest, demand and dishonor and nonpayment of this Note, and expressly agree
that the maturity of this Note, or any payment due under this Note, may be
extended from time to time without in any way affecting the liability of the
undersigned or said endorsers or guarantors.

         Payments of principal on this Note, and the rights of the holder
hereof, are subordinate to Senior Indebtedness (as defined in the Subordination
Agreement), and the rights of the holders thereof, to the extent specified in
the Subordination Agreement.
