exchange for a new Note or Notes equal to the principal amount remaining unpaid
on the surrendered Note, or (ii) be made available to the Company, at the
Company's principal office, for notation thereon of the portion of the principal
so prepaid or exchanged. In case the entire principal amount of any Note is
prepaid, such Note shall be surrendered to the Company, upon its request,

shall be issued in lieu of a Note the entire principal amount of which has been
prepaid.

may otherwise designate by notice to the Company, in each case without
presentment and, subject to Section 2.4(ii) above, without notations being made
thereon, except that any such Note so paid or prepaid in full shall be
surrendered to the Company, upon its written request, for cancellation. Any wire
transfer shall identify such payment in the manner set forth in Schedule I and
shall identify the payment as principal, Make-Whole Amount, if any, and/or
interest. Any payment made pursuant to this Section 2.5 shall be deemed received
on the payment date only if received before Noon, Chicago time. Payments
received after Noon, Chicago time, shall be deemed received on the next
succeeding Business Day, with the Make-Whole Amount, if any, and/or interest
payable to such Business Day.

     2.6. Allocation of Payments. In the case of a prepayment pursuant to
Section 2.2(a), if less than the entire principal amount of all of the Notes
outstanding is to be paid, the Company will prorate the aggregate principal
amount to be prepaid among the outstanding Notes in proportion to the unpaid
principal amounts thereof.

     2.7. Payments Due on Saturdays, Sundays and Holidays. If any interest
payment date on the Notes or the date fixed for any other payment of any Note or
exchange of any Note is a day other than a Business Day, then such payment or
exchange need not be made on such date but may be made on the next succeeding
Business Day, with the Make-Whole Amount, if any, and/or interest payable to the
actual date of payment.

pursuant to Title I or IV of ERISA or to such penalty or excise tax provisions
