B.    Whereas, capitalized terms used herein shall have the respective meanings ascribed thereto in the Original Note Purchase Agreement unless herein defined or the context shall otherwise require;

C.    Whereas, the Company and the Required Holders now desire to amend the Original Note Purchase Agreement in the respects, but only in the respects, hereinafter set forth; and

D.    Whereas, all requirements of law have been fully complied with and all other acts and things necessary to make this First Amendment a valid, legal and binding instrument according to its terms for the purposes herein expressed have been done or performed.

Now, therefore, in consideration of good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the Company and the Required Holders do hereby agree as follows:

SECTION 1.    Amendments to Original Note Purchase Agreement.

1.1.Section 7.2(a) of the Original Note Purchase Agreement shall be and hereby is amended and restated in its entirety to read as follows:

(a)    Covenant Compliance — setting forth the information (including detailed calculations) required in order to establish whether the Company was in compliance with the requirements of Section 10.1 through Section 10.5, inclusive, Section 10.7 and each Additional or More Restrictive Covenant during the quarterly or annual period covered by the statements then being furnished (including with respect to each such Section, where applicable, the calculations of the maximum or minimum amount, ratio or percentage, as the case may be, permissible under the

terms of such Sections, and the calculation of the amount, ratio or percentage then in existence). In the event that the Company or any Restricted Subsidiary has made an election to measure any Indebtedness using fair value (which election is being disregarded for purposes of determining compliance with this Agreement pursuant to Section 22.3) as to the period covered by any such financial statement, such Senior Financial Officer’s certificate as to such period shall include a reconciliation from GAAP with respect to such election; and

1.2.The Original Note Purchase Agreement shall be and hereby is amended by inserting a new Section 9.10 to read as follows:

Section 9.10Excess Leverage Fee. Upon delivery by the Company of a Notice of Acquisition Holiday Period, the Company agrees that, in addition to interest accruing on the Notes, the Company will pay to each holder of a Note a fee at a rate per annum equal to 0.50% (each such fee, an “Excess Leverage Fee”) on the outstanding principal amount of each Note held by such holder during the Acquisition Holiday Period related to such Notice of Acquisition Holiday Period. The Excess Leverage Fee with respect to each Note shall be calculated on the same basis as interest on such Note is calculated and shall be paid in arrears at the same time accrued interest is paid on such Note and, for the avoidance of doubt, all accrued and unpaid Excess Leverage Fee on any principal amount being paid or prepaid shall be paid concurrently with such principal. Any overdue payment of any Excess Leverage Fee shall accrue interest at a rate per annum from time to time equal to the Default Rate applicable to the applicable Note, payable in arrears at the same time accrued interest is paid on such Note (or, at the option of the registered holder thereof, on demand). The payment of any Excess Leverage Fee shall not constitute a waiver of any Default or Event of Default.

The Company will pay the Excess Leverage Fee by separate wire transfer in Dollars with respect to (a) each Series 2019-C Note, (b) each Swapped Note and (c) each Series 2019-B Note that is not a Swapped Note where the holder thereof has elected by written notice to the Company to receive the Excess Leverage Fee in Dollars, and the Company will pay the Excess Leverage Fee by separate wire transfer in Euro to the holders of all other Notes. For purposes of calculating the amount of any Excess Leverage Fee with respect to any Series 2019-B Note that is not a Swapped Note that is payable in Dollars, the amount of the Excess Leverage Fee at the time of such determination shall be converted from Euros into Dollars at the current Euro/Dollar exchange rate, as determined as of 10:00 a.m. (New York time) one Business Day prior to the day such Excess Leverage Fee is payable as indicated on the applicable screen of Bloomberg Financial Markets, and any such calculation reported by the holder of such Note to the Company in reasonable detail shall be binding on the Company, absent demonstrable error.

Section 9.11Most Favored Lender Provision. If at any time the Bank Credit Agreement or any Note Purchase Agreement or any guaranty in respect of any thereof (an “MFL Agreement”) shall include any Financial Covenant and such provision (a) is different from the subject matter of the financial covenants in Section 10 or the related definitions in Schedule B, or (b) is similar to the subject matter of any financial covenant in Section 10 and related definitions in Schedule B, but contains one or more percentages, amounts, ratios or formulas that is more restrictive than those set forth herein or more beneficial to the lender(s) and/or holder(s) under such MFL Agreement (any such provision, together with any related definitions (including, any term defined therein with reference to the application of GAAP, as identified in such MFL Agreement), an “Additional or More Restrictive Covenant”; provided that, in the case of the foregoing clause (b), such covenant or similar restriction shall be deemed an Additional or More Restrictive Covenant only to the extent that it is more restrictive or more beneficial), then the Company shall promptly, and in any event within 10 Business Days thereof, provide a Most Favored Lender Notice to each holder of the Notes with respect to each such Additional or More Restrictive Covenant. Thereupon, unless waived in writing by the Required Holders within 10 Business Days of the holders’ receipt of such notice, such Additional or More Restrictive Covenant shall be deemed incorporated by reference into this Agreement, mutatis mutandis, as if set forth fully herein, effective as of the date when such Additional or More Restrictive Covenant became effective under the relevant MFL Agreement. Any Additional or More Restrictive Covenant incorporated into this Agreement pursuant to this provision, (1) shall remain unchanged herein notwithstanding any temporary waiver of such Additional or More Restricted Covenant under the relevant MFL Agreement, (2) shall be deemed automatically amended herein to reflect any subsequent amendments agreed and implemented in relation to such Additional or More Restrictive Covenant under the relevant MFL Agreement and (3) shall be deemed deleted from this Agreement at such time as such Additional or More Restrictive Covenant is deleted or otherwise removed from or is no longer in effect under or pursuant to the relevant MFL Agreement or if the relevant MFL Agreement has been terminated and has no Indebtedness or commitments outstanding thereunder; provided that in no event shall the effect of any event contemplated by clause (2) or (3) above result in any covenant set forth in Section 10 being less restrictive than it was on the First Amendment Effective Date or being deleted herefrom; provided further that (i) in each case that any consideration is paid or provided to any holder of Indebtedness under the relevant MFL Agreement in connection with an event contemplated by clause (2) or (3) above (other than in connection with the extension of the term of the relevant MFL Agreement, refinancing

3

or replacing the relevant MFL Agreement or repayment in full of the relevant MFL Agreement in connection with its termination) then the Company shall pay to the holders of the Notes equivalent consideration, determined on a pro rata basis in proportion to the relative outstanding principal amount of the Notes and the principal amount of Indebtedness outstanding under the relevant MFL Agreement, substantially concurrently therewith; (ii) no Additional or More Restrictive Covenant shall be so deemed automatically amended or deleted during any time that a Default or Event of Default has occurred and is continuing and (iii) no Additional or More Restrictive Covenant shall be so deemed automatically amended in a manner that would cause it to become less restrictive or deleted, unless the Company shall have first provided notice thereof to each holder of the Notes. In determining whether a breach of any Financial Covenant incorporated by reference into this Agreement pursuant to this Section 9.11 shall constitute an Event of Default, the period of grace, if any, applicable to such Additional or More Restrictive Covenant in the relevant MFL Agreement shallapply notwithstanding the grace period set forth in Section 11(c)(1).

4

Assets (“Excess Priority Indebtedness”) shall be attributable solely to Indebtedness of Foreign Subsidiaries (that are Restricted Subsidiaries) incurred in connection with such Repatriation Transactions and (2) at all times when there is Excess Priority Indebtedness outstanding, the Consolidated Net Leverage Ratio shall not be greater than (i) 2.75 to 1.00 or (ii) during an Acquisition Holiday Period, 3.25 to 1.00.
