                                 AMENDED AND RESTATED

                                    REVOLVING NOTE

$[AMOUNT]                                                    Chicago, Illinois
                                                             December 31, 2002


     FOR VALUE RECEIVED, the undersigned (the "BORROWERS" and each a
"BORROWER") unconditionally promise to pay to the order of [NAME] (the
"LENDER"), on the Revolver Termination Date, or, if earlier, upon the date
for payment established under the provisions of Section 6.2 or 12.2 of the
Credit Agreement (as defined below), at the Lender's office at [ADDRESS], or
at such other place as the holder of this Revolving Note (this "NOTE") may
from time to time designate in writing, in lawful money of the United States
of America and in immediately available funds, the principal sum of [AMOUNT]
($[AMOUNT]) or, if less, the Lender's Percentage of the aggregate unpaid
principal amount of all Revolving Loans made under Section 2.2(A) of the
Credit Agreement.  This Note is referred to in and was executed and delivered
under the Amended and Restated Credit Agreement dated as of December 31, 2002
(as such agreement may be amended, restated, supplemented or otherwise
modified from time to time, the "CREDIT AGREEMENT"), among the Borrowers, as
borrowers, the Lender and the other lenders party thereto, as lenders,
LaSalle Bank National Association, a national banking association, as
administrative agent for the Lenders (in such capacity, the "ADMINISTRATIVE
AGENT") and National City Bank, a national banking association, as
syndication agent for the Lenders (in such capacity, the "SYNDICATION AGENT",
and together with the Administrative Agent, the "AGENTS").  Capitalized terms
used in this Note and not otherwise defined have the meanings assigned to
such terms in the Credit Agreement.

     The Borrowers further promise to pay interest on the outstanding
principal amount of the indebtedness represented by this Note from the date
of this Note until payment in full of such indebtedness at the applicable
rates set forth in Section 4.1 of the Credit Agreement.  Except as otherwise
provided in the Credit Agreement, interest is payable quarterly in arrears
not later than the last Business Day of each calendar quarter and computed on
the basis of a 360-day year for the actual number of days elapsed.

     Except as otherwise provided in the Credit Agreement, if payment under
this Note becomes due and payable on a Saturday, Sunday or legal holiday
under the laws of the State of Illinois, the due date of such payment is
extended to the next succeeding Business Day and interest is payable on such
payment during such extension at the rate specified in the Credit Agreement.
In no contingency or event whatsoever will interest charged under this Note,
however such interest may be characterized or computed, exceed the highest
rate permissible under any law that a court of competent jurisdiction, in a
final determination, deems applicable to this Note.  In the event that such a
court determines that the Lender has received interest under this Note in
excess of the highest rate applicable to this Note, any such excess interest
collected by the Lender is deemed to have been a repayment of principal and
will be so applied.

     Except as otherwise agreed in the Credit Agreement, payments received by
the Lender from the Borrowers on this Note will be applied first to the
payment of interest that is due and payable and only thereafter to the
outstanding principal balance of the indebtedness represented by this Note.

     This Note is subject to prepayment at the option of the Borrowers as
provided in the Credit Agreement and mandatory prepayment as provided in the
Credit Agreement.  Any such prepayments will be applied in the manner set
forth in the Credit Agreement.

     DEMAND, PRESENTMENT, PROTEST AND NOTICE OF NONPAYMENT AND PROTEST ARE
WAIVED BY THE BORROWERS.
