        accompanied by a written calculation of the Funded Debt to Adjusted
        EBITDA Ratio certified by a chief financial officer as of the end of the
        fiscal period for which such financial statements are delivered. If such

        financial statements and written calculation the Applicable Margin shall
        be adjusted in accordance therewith; provided, however, that if

        such written calculation are finally delivered, the Applicable Margin
        shall be conclusively presumed to equal the highest Applicable Margin
        specified in the pricing table set forth above. Notwithstanding anything
        to the contrary above, Subject to Sections 2.5 and 2.10 below, until at

        later than 11:00 A.M., Chicago time, on the day of such prepayment
        (which shall be a Business Day), specifying the date and amount of

        inverse order of maturity to the remaining installments thereof, and no
