2. The Administrative Agent has a schedule (the “Replacement Term Loan Commitment Schedule”) which sets forth, in Euros, the allocated commitments received by it (“Replacement Term Loan Commitments”) from various Lenders (including Persons which would become Lenders on the Third Amendment Effective Date) (each, a “Replacement Lender”) to make Replacement Term Loans on the Third Amendment Effective Date in accordance with the relevant provisions of this Amendment. The Administrative Agent has notified each Replacement Lender of its allocated Replacement Term Loan Commitment, and each of the Replacement Lenders is listed as a signatory to this Amendment. Upon the request of the Parent Borrower, the Administrative Agent shall furnish it a copy of the Replacement Term Loan Commitment Schedule. On the Third Amendment Effective Date, all then outstanding Tranche B Euro Term Loans shall be refinanced in full as follows (and as described in following Part B.3.):

(i) the aggregate principal amount of Tranche B Euro Term Loans of each Lender which does not have a Replacement Term Loan Commitment shall be repaid in full in cash (in Euros); and

(ii) the aggregate principal amount of Tranche B Euro Term Loans of each Lender which has a Replacement Term Loan Commitment shall automatically be converted into Replacement Term Loans; provided that (x) if the Replacement Term Loan Commitment of the respective Lender exceeds the then outstanding principal amount of its Tranche B Euro Term Loans, such Lender shall lend cash in an amount equal to such difference as set forth in Part B.3. below and (y) if the Replacement Term Loan Commitment of the respective Lender is less than the aggregate principal amount of its then outstanding Tranche B Euro Term Loans, the principal amount of its then outstanding Tranche B Euro Term Loans shall be repaid in cash in Euros in an amount equal to such difference.

3. On the Third Amendment Effective Date, each Lender with a Replacement Term Loan Commitment shall fund its Replacement Term Loans to the Parent

Borrower as Eurocurrency Loans in an aggregate principal amount equal to such Lender’s Replacement Term Loan Commitment as follows:

(i) each Replacement Lender which has then outstanding Tranche B Euro Term Loans, shall fund its Replacement Term Loans by converting its then outstanding principal of Tranche B Euro Term Loans (up to the amount of its Replacement Term Loan Commitment) into Replacement Term Loans as (and to the extent) provided in Part B.2.(ii) above;

(ii) each Replacement Lender which has then outstanding Tranche B Euro Term Loans and which has a Replacement Term Loan Commitment which exceeds the amount of its then outstanding Tranche B Euro Term Loans shall also fund an amount equal to such excess in Euros to the Parent Borrower; and

(iii) each Replacement Lender which has no then outstanding Tranche B Euro Term Loans shall fund the full amount of its Replacement Term Loan Commitment in Euros to the Parent Borrower.

4. The Parent Borrower shall give the Administrative Agent, for distribution to the Replacement Lenders and the Lenders of then outstanding Tranche B Euro Term Loans, written notice of the funding of the Replacement Term Loans at least one Business Day prior to the Third Amendment Effective Date, which notice shall be in form and substance reasonably satisfactory to the Administrative Agent and shall be deemed to be both a notice of borrowing and, subject to Part B.7. below, of prepayment for purposes of Section 4.12 of the Credit Agreement. All Interest Periods applicable to Tranche B Euro Term Loans shall continue in effect (for the same amount of principal of Replacement Term Loans) after the Third Amendment Effective Date and shall apply to the Replacement Term Loans made on the Third Amendment Effective Date (until such Interest Periods expire, at which time subsequent Interest Periods shall be determined in accordance with the provisions of Section 4.2 of the Credit Agreement). The Replacement Term Loans of the various Replacement Lenders shall be allocated ratably to such Interest Periods (based upon the relative principal amounts subject thereto prior to the Third Amendment Effective Date), with the effect being that Tranche B Euro Term Loans which are converted hereunder shall continue to be subject to the same Interest Periods and any amounts funded in cash on the Third Amendment Effective Date shall be ratably allocated to the various Interest Periods as described above. To the extent any Replacement Lender which is funding Replacement Term Loans in cash suffers any loss as a result of funding its Replacement Term Loans during an Interest Period rather than on the first day thereof (after taking such steps as may be reasonably available to it to mitigate or avoid such loss), it shall provide prompt notice thereof to the Parent Borrower through the Administrative Agent (certifying that it has suffered such a loss and the amount thereof, describing in reasonable detail the nature of such loss and the reasons therefor, and setting forth a reasonably detailed explanation of the calculation thereof) and the Parent Borrower shall promptly following receipt of such request reimburse it for such loss so sustained.

5. Each Replacement Lender shall be required to execute and deliver a counterpart of this Amendment on or prior to the Third Amendment Effective Date, and any such Person which was not already a Lender under the Credit Agreement hereby agrees that it shall be party to the Credit Agreement (as amended from time to time) as a Lender as fully as if it were a

Lender originally party thereto, and agrees to furnish to the Administrative Agent from time to time following any request therefor all documentation required of Lenders party to the Credit Agreement on the Closing Date, as fully as if it were a party thereto on the Closing Date.

6. The Parent Borrower hereby agrees that, upon request to the Administrative Agent by any Replacement Lender made on or prior to the Third Amendment Effective Date, in order to evidence such Replacement Lender’s Replacement Term Loans hereunder, the Parent Borrower will execute and deliver to such Replacement Lender a Tranche B Euro Term Note, with appropriate insertions therein as to payee, date and principal amount, payable to the order of such Replacement Lender and in a principal amount equal to the unpaid principal amount of the Replacement Loans made by such Replacement Lender to the Parent Borrower. Each such Tranche B Euro Term Note shall (x) be dated the Closing Date, (y) be payable as provided in Section 2.6(b)(ii) of the Credit Agreement and (z) provide for the payment of interest in accordance with Section 4.1 of the Credit Agreement. If any Replacement Lender which was already a Lender of Tranche B Euro Term Loans prior to the Third Amendment Effective Date requests a replacement Tranche B Euro Term Note hereunder, such Lender shall surrender the respective Tranche B Euro Term Note, if any, held by it. Any Tranche B Euro Term Notes so surrendered shall be delivered to the Administrative Agent and returned by it to the Parent Borrower marked “cancelled.” If a Replacement Lender was already a Lender of Tranche B Euro Term Loans prior to the Third Amendment Effective Date, and is a holder of a Tranche B Euro Term Note issued prior to the Third Amendment Effective Date evidencing same, such Tranche B Euro Term Note shall continue to evidence its outstanding Replacement Term Loans following the Third Amendment Effective Date unless replaced in accordance with the foregoing provisions, as and to the extent otherwise contemplated by the Credit Agreement (although if the respective Replacement Lender is making Replacement Term Loans in excess of the aggregate principal amount of such Tranche B Euro Term Note, it shall be entitled to receive a replacement Note in accordance with the preceding provisions).

7. On the Third Amendment Effective Date, the Parent Borrower shall pay (a) in cash all interest accrued on the Tranche B Euro Term Loans through the Third Amendment Effective Date and (b) to each Tranche B Euro Term Lender that is not a Replacement Lender, and to each Replacement Lender to the extent such Lender is repaid cash pursuant to clause (y) in the proviso to Part B.2.(ii) above, any breakage loss or expenses due under Section 4.12 of the Credit Agreement (it being understood that existing Interest Periods of the Tranche B Euro Term Loans held by Replacement Lenders prior to the Third Amendment Effective Date shall continue on and after the Third Amendment Effective Date and shall accrue interest at the Applicable Margin in effect on and after the Third Amendment Effective Date).

(i) the Administrative Agent shall have received the notice required by Part B.4. of this Amendment (with the number of days notice as specified therein having been provided);
