In connection with any Discounted Voluntary Prepayment of a given Tranche of Tender Term Loans, the relevant Tendering Borrower will notify each Lender with such Tender Term Loans in writing (the “Prepayment Notice”) that such Tendering Borrower desires to prepay such Tender Term Loans with proceeds in an aggregate amount specified by such Tendering Borrower (which amount shall be not less than the amount necessary to prepay U.S.$25,000,000 (or, €20,000,000, in the case of Tranche E Term Loans) of par principal amount of Tender Term Loans in the aggregate in each case, determined using the lowest Discount (as defined below) in the range specified by such Tendering Borrower below) (each, a “Prepayment Amount”) at a discount (which is expected to be within a range to be specified by such Tendering Borrower with respect to each Discounted Voluntary Prepayment; the “Discount”) equal to a percentage of par of the principal amount of such Tender Term Loans being prepaid; provided that (i) the aggregate Prepayment Amounts for all Discounted Voluntary Prepayments undertaken by the Tendering Borrowers of all Tender Term Loans prepaid during the Discounted Voluntary Prepayment Period shall not exceed U.S.$150,000,000 in the aggregate (for such purpose, taking the U.S. Dollar Equivalent of the Prepayment Amount with respect to any Tranche E Term Loans subject to a Discounted Voluntary Prepayment (determined as of the date of such Discounted Voluntary Prepayment, and excluding any voluntary prepayments of any Tender Term Loans made in accordance with the Credit Agreement as in effect prior to the Third Amendment Effective Date), and (ii) the Tendering Borrowers may issue no more than four Prepayment Notices that result in a Discounted Voluntary Prepayment (and make no more than four Discounted Voluntary Prepayments) in any twelve month period.

-3-

Borrower and its Domestic Subsidiaries used to finance a Discounted Voluntary Prepayment by the Canadian Borrower shall be permitted only to the extent such cash is otherwise permitted to be invested in the Canadian Borrower pursuant to Section 10.04 of the Credit Agreement.

(b) In connection with a Discounted Voluntary Prepayment of a given Tranche of Tender Term Loans, the relevant Tendering Borrower will allow each applicable Tender TL Lender to specify (a “Prepayment Offer”) a discount to par (the “Acceptable Discount”) for a principal amount (subject to rounding requirements specified by the Prepayment Agent) of such Tender Term Loans at which such Tender TL Lender is willing to permit such Discounted Voluntary Prepayment (and which shall be within any range specified by such Tendering Borrower with respect to such Discounted Voluntary Prepayment). Each Tendering Borrower will accept Prepayment Offers in the order of lowest to highest prepayment price specified by the respective Tender TL Lenders in the Prepayment Offers so as to enable such Tendering Borrower to complete the Discounted Voluntary Prepayment for the Prepayment Amount. Based on the Acceptable Discounts and principal amounts of such Tender Term Loans specified by the Tender TL Lenders, the applicable discount (the “Applicable Discount”) for the Discounted Voluntary Prepayment will be the highest Acceptable Discount (i.e., the lowest prepayment price) at which the relevant Tendering Borrower can complete the Discounted Voluntary Prepayment for the full Prepayment Amount and which is within the range for the Discount specified by such Tendering Borrower. Each Tendering Borrower shall prepay such Tranche of Tender Term Loans (or the respective portions thereof) offered by Tender TL Lenders at the Acceptable Discounts specified by each such Tender TL Lender that are equal to or greater than the Applicable Discount (“Qualifying Tender Term Loans”) at the Applicable Discount; provided that if the aggregate proceeds required to prepay Qualifying Tender Term Loans (disregarding any interest payable under Section 2.1(c) hereof) would exceed the Prepayment Amount for such Discounted Voluntary Prepayment, the relevant Tendering Borrower shall prepay such Qualifying Tender Term Loans at the Applicable Discount ratably based on the respective principal amounts of such Qualifying Tender Term Loans (subject to rounding requirements specified by the Prepayment Agent).

(c) All Tender Term Loans prepaid by the Tendering Borrowers pursuant to this Section 2.1 shall be accompanied by payment of accrued and unpaid interest on the par principal amount so prepaid to, but not including, the date of prepayment.

(d) The par principal amount of Tender Term Loans of a given Tranche prepaid pursuant to this Section 2.1 shall be applied to reduce the remaining Scheduled Repayments of such Tranche of Tender Term Loans in indirect order of maturity.

(e) Each Discounted Voluntary Prepayment shall be consummated pursuant to procedures (including as to timing, settlement, irrevocability of Prepayment Notices and acceptances of Prepayment Offers, rounding and minimum amounts, applicable Borrowings of accepted Tender Term Loans and other notices by the Tendering Borrowers and Tender TL Lenders and determination of Applicable Discount) established by the Prepayment Agent in consultation with the Tendering Borrowers; it being understood and agreed that (x) each Tendering Borrower shall have the right to revoke its offer for a Discounted Voluntary Prepayment and rescind its Prepayment Notice therefor at its discretion at any time prior to such Tendering Borrower’s delivery of a final notice of acceptance of the related Prepayment Offers,

-4-

(y) the settlement date for payment of accepted Prepayment Offers shall not be later than 30 days after the applicable Tendering Borrower’s delivery of a final notice of acceptance therefor, and (z) unless otherwise determined by the Prepayment Agent, all Discounted Voluntary Prepayments of a given Tranche of Tender Term Loans shall be applied to all then outstanding Borrowings of such Tender Term Loans on a pro rata basis (based on the relative sizes of the various outstanding Borrowings of such Tranche of Tender Term Loans), so that all Lenders with outstanding Tender Term Loans under the applicable Tranche will continue to participate in each then outstanding Borrowing of such Tranche of Tender Term Loans on a pro rata basis (based upon the then outstanding principal amount of all Tender Term Loans under such Tranche after giving effect to such Discounted Voluntary Prepayment as if made at par). The Lenders hereby further agree that, following a Discounted Voluntary Prepayment of a given Tranche of Tender Term Loans and notwithstanding anything to the contrary contained in the Credit Agreement, (i) interest in respect of such Tender Term Loans may be made on a non-pro rata basis among the Lenders holding such Tender Term Loans to reflect the payment of accrued interest to certain Tender TL Lenders as provided in Section 2.1(c) hereof and (ii) all subsequent prepayments and repayments of such Tender Term Loans (other than a Discounted Voluntary Prepayment) shall be made on a pro rata basis among the Lenders holding such Tender Term Loans (based upon the then outstanding principal amounts of such Tender Term Loans of such Lenders after giving effect to any Discounted Voluntary Prepayment as if made at par).

(f) Except (i) for purposes of the definition of “Adjusted Excess Cash Flow” appearing in Section 1 of the Credit Agreement (as to which a Discounted Voluntary Prepayment shall be treated as specified in such definition as amended hereby) and (ii) as otherwise expressly provided herein, each Discounted Voluntary Prepayment of a given Tranche of Tender Term Loans shall constitute a voluntary prepayment of such Tranche of Tender Term Loans for all purposes under the Credit Agreement (including clause (f)(ii) of the definition of “Excess Cash Flow” appearing in Section 1 of the Credit Agreement and Sections 5.01(ii) and (iii) of the Credit Agreement).

(g) The Lenders hereby (i) consent to the transactions described in this Section 2.1 notwithstanding anything to the contrary in the Credit Agreement, (ii) waive the requirements of any provision of the Credit Agreement (including, without limitation, Sections 5.01(iv) and 13.06) that might otherwise prohibit the Discounted Voluntary Prepayment Transaction or result in a Default or an Event of Default as a result of the Discounted Voluntary Prepayment Transaction and (iii) agree that no Discounted Voluntary Prepayment shall give rise to an obligation by any Tender TL Lender to purchase participations pursuant to Section 13.06 of the Credit Agreement with amounts received by it from such Discounted Voluntary Prepayment.

(h) This Third Amendment shall not (i) require any Tendering Borrower to undertake any Discounted Voluntary Prepayment during the Discounted Voluntary Prepayment Period or (ii) limit or restrict any Tendering Borrower from making voluntary prepayments of the Loans in accordance with the provisions of the Credit Agreement as in effect prior to the Third Amendment Effective Date.
