Currency or of a Borrowing of Bankers’ Acceptance Loans (as the case may be),
(ii) each date of a continuation of a Eurocurrency Revolving Loan denominated in
an Alternate Currency or of a Borrowing of Bankers’ Acceptance Loans (as the
case may be) pursuant to Section 2.07, and (iii) the last Business Day of each
fiscal quarter, and such additional dates as the Administrative Agent shall
determine or the Majority Lenders under the applicable Revolving Facility shall
require.

(l) The definition of “Revolving Facility Commitment” is hereby amended and
restated in its entirety as follows:

“Revolving Facility Commitment” shall mean, with respect to each Revolving
Facility Lender, the commitment of such Revolving Facility Lender to make
Revolving Facility Loans pursuant to Section 2.01(b), expressed as an amount
representing the maximum aggregate permitted amount of such Revolving Facility
Lender’s Revolving Facility Credit Exposure hereunder, as such commitment may be
(a) reduced from time to time pursuant to Section 2.08, (b) reduced or increased
from time to time pursuant to assignments by or to such Lender under
Section 9.04, and (c) increased, extended or replaced as provided under
Section 2.21, 2.22 or 2.23. The initial amount of each Lender’s Revolving
Facility Commitment is set forth on Schedule 2.01, or in the Assignment and
Acceptance, Incremental Assumption Agreement, Extension Amendment or Refinancing
Amendment pursuant to which such Lender shall have assumed its Revolving
Facility Commitment, as applicable. The aggregate amount of the Lenders’
Revolving Facility Commitments on the 2015 Revolving Facility Effective Date
(after giving effect to (x) the termination of the Revolving Facility
Commitments as in effect immediately prior to the 2015 Revolving Facility
Effective Date and (y) the establishment of the 2015 Revolving Facility
Commitments) is $500,000,000. On the 2015 Revolving Facility Effective Date,
there is only one Class of Revolving Facility Commitments, consisting of the
2015 Revolving Facility Commitments. After the 2015 Revolving Facility Effective
Date, additional Classes of Revolving Facility Commitments may be added or
created pursuant to Extension Amendments or Refinancing Amendments.

the following text at the end thereof:

“For the avoidance of doubt, as of the 2015 Revolving Facility Effective Date,
the 2015 Revolving Facility Lenders shall constitute the “Revolving Facility
Lenders” hereunder.”

(n) The definition of “Revolving Facility Loan” is hereby amended by inserting
the text “(including, without limitation, the 2015 Revolving Facility Loans)”
immediately prior to the period at the end of the second sentence thereof.

(o) The definition of “Revolving Facility Maturity Date” is hereby amended and
restated in its entirety as follows:

“Revolving Facility Maturity Date” shall mean, as the context may require,
(a) with respect to the Revolving Facility in effect on the Closing Date,
March 19, 2019, (b) with respect to the Revolving Facility established pursuant
to the Second Amendment, March 19, 2019 and (c) with respect to any other
Classes of Revolving Facility Commitments, the maturity dates specified therefor
in the applicable Extension Amendment or Refinancing Amendment.

“(a) General. Subject to the terms and conditions set forth herein, the Lux
Borrower may request the issuance of one or more letters of credit denominated

trade obligations of the Parent and its Subsidiaries incurred in the ordinary
course of business (such letters of credit issued for such purposes, “Trade
Letters of Credit”) and (y) standby letters of credit issued for any other
lawful purposes of the Parent and its Subsidiaries (such letters of credit
issued for such purposes, “Standby Letters of Credit”; each such letter of
credit issued hereunder, a “Letter of Credit” and collectively, the “Letters of
Credit”) for its own account (although, at the request of the Lux Borrower, a
Letter of Credit may be issued that states that it is issued for the account of
the Parent or any of its Subsidiaries, in which case any such Letter of Credit
shall be deemed issued for the joint and several account of the Lux Borrower
and, as applicable, the Parent or such Subsidiary) in a form reasonably
acceptable to the Administrative Agent and the applicable Issuing Bank, at any
time and from time to time during the applicable Availability Period and prior
to the date that is five Business Days prior to the applicable Revolving
Facility Maturity Date. Except with respect to additional conditions to the
issuance, amendment, extension, renewal or increase in the amount of Letters of
Credit as to which the Lux Borrower and the applicable Issuing Bank may agree,
in the event of any inconsistency between the terms and conditions of this
Agreement and the terms and conditions of any form of letter of credit
application or other agreement submitted by the Lux Borrower to, or entered into
by such Borrower with, an Issuing Bank relating to any Letter of Credit, the
terms and conditions of this Agreement shall control.”

 

-12-

--------------------------------------------------------------------------------

(q) Section 2.05(b) of the Credit Agreement is hereby amended by amending and
restating the final sentence thereof as follows:

“A Letter of Credit shall be issued, amended or extended only if (and upon
issuance, amendment or extension of each Letter of Credit each Borrower shall be
deemed to represent and warrant that), after giving effect to such issuance,
amendment or extension, (x) the Dollar Equivalent of the Revolving L/C Exposure
shall not exceed $150,000,000, (y) the Dollar Equivalent of the Revolving
Facility Credit Exposure shall not exceed the applicable Revolving Facility

Agreement (so long as after giving effect to such reallocation, the Revolving
Facility Credit Exposure of each 2015 Revolving Facility Lender does not exceed
such Lender’s 2015 Revolving Facility Commitment as in effect on the 2015
Revolving Facility Effective Date). On and after the 2015 Revolving Facility
Effective Date, the 2015 Revolving Facility Lenders (as well as any other
Revolving Facility Lenders from time to time party hereto) will be required, in
accordance with their Revolving Facility Percentages, to fund L/C Disbursements

Revolving Facility Loans, completed in conformity with Section 2.09(e) above;
provided that if any such Note is not so surrendered, then from and after the
2015 Revolving Facility Effective Date such Note shall be deemed to evidence the
2015 Revolving Facility Loans theretofore evidenced by such promissory note.”

(v) Schedule 2.13(g) of the Credit Agreement is hereby amended by inserting the
following text immediately following Section 6 thereof:

6.1 Notwithstanding anything provided for in this Schedule 2.13(g) or the Credit
Agreement, whenever the Lux Borrower requests a Borrowing of Bankers’ Acceptance
Loans, each Non-B/A Lender may, in lieu of purchasing Drafts, make a loan (a
“B/A Equivalent Loan”) in an amount equal to the aggregate B/A Discount Proceeds
that would have otherwise resulted from such purchase.

6.1.1 The term of the B/A Equivalent Loan shall be identical to the term of the
Draft that such non-B/A Lender would have otherwise purchased.

6.1.2 The interest rate applicable to a B/A Equivalent Loan shall be that rate
that, when applied to the B/A Discount Proceeds over the term of the B/A
Equivalent Loan, shall result in the aggregate of principal and interest payable
on the maturity date of such B/A Equivalent Loan equal to the Face Amount of the
Drafts that would have been otherwise purchased by such Non-B/A Lender.

6.1.3 The B/A Equivalent Loan may, at the election of the applicable Non-B/A
Lender be evidenced by a B/A Equivalent Note and the terms of this Schedule
2.13(g) shall apply thereto. Notwithstanding the foregoing, the Lux Borrower and
each Non-B/A Lender acknowledge and agree that from time to time certain Non-B/A
Lenders may elect not to receive B/A Equivalent Notes, and the Lux Borrower and
each applicable Non-B/A Lender agrees that with respect to any such Non-B/A
Lender, in lieu of receiving B/A Equivalent Notes, the applicable B/A Equivalent
Loan shall be evidenced by an account maintained by such Non-B/A Lender and/or
the Administrative Agent in accordance with Sections 2.09(b) and 2.09(c) of the
Credit Agreement.
