W I T N E S S E T H:

WHEREAS, the Borrower, the Exiting Lenders, the Extending Lenders and the Administrative Agent are parties to that certain Credit Agreement, dated as of July 6, 2012 (as amended by Amendment No. 1 thereto dated as of February 8, 2013 and as otherwise heretofore supplemented or modified, the “Credit Agreement”);

WHEREAS, pursuant to Section 2.14 of the Credit Agreement, the Borrower has requested that the Revolving Credit Commitment Termination Date for each Lender be extended to the date that is 364 days after the Revolving Credit Commitment Termination Date in effect immediately prior to giving effect to this Amendment (the “Extension”);

WHEREAS, the Borrower has requested that the Aggregate Commitments be increased to $1,150,000,000, which such increase shall be effected without the Borrower exercising its rights under Section 2.15 of the Credit Agreement; and

WHEREAS, the parties hereto are willing to agree to the foregoing, subject to the terms and conditions set forth herein;

NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto hereby agree as follows:

SECTION 1. Definitions. Unless otherwise defined in this Amendment, capitalized terms used in this Amendment which are defined in the Credit Agreement, as amended hereby (the “Amended Credit Agreement”), shall have the meanings assigned to such terms in the Amended Credit Agreement. The interpretive provisions set forth in Section 1.02 of the Credit Agreement shall apply to this Amendment.

SECTION 2. Extension of Revolving Credit Commitment Termination Date. Each Extending Lender and each New Lender (a) agrees to the Extension and (b) agrees that, effective as of the date hereof, the Revolving Credit Commitment Termination Date with respect to such Person’s Commitment shall be July 4, 2014 (which is the day that is 364 days after the Revolving Credit Commitment Termination Date in effect on the date hereof immediately prior to giving effect to this Amendment).

SECTION 3. New Lenders; Increased Commitments of Certain Extending Lenders; Termination of Commitments of Exiting Lenders.

Effective as of the date hereof:

(a) each New Lender hereby (i) provides a Commitment equal to the amount set forth opposite such New Lender’s name on Schedule 2.01(a) attached hereto and (ii) becomes a Lender under the Amended Credit Agreement (as it may be further amended, restated, supplemented or otherwise modified from time to time) for all purposes to the same extent as if originally a party thereto and shall be bound thereby and entitled to the benefits thereof;

(b) each Extending Lender whose Commitment amount set forth opposite such Extending Lender’s name on Schedule 2.01(a) attached hereto is greater than such Extending Lender’s Commitment in effect immediately prior to giving effect to this Amendment hereby increases its Commitment such that, after giving effect to this Amendment, such Extending Lender has a Commitment equal to the amount set forth opposite its name on Schedule 2.01(a) attached hereto; and

(c) pursuant to Section 10.15 of the Credit Agreement, the Commitment of each Exiting Lender is hereby terminated in full and each Exiting Lender shall cease to be a party to the Credit Agreement and shall no longer be a Lender. Each Exiting Lender joins in the execution of this Amendment solely for the purposes of acknowledging the termination of its Commitment pursuant to this Section 3(c).

For the avoidance of doubt, the increase in the Aggregate Commitments pursuant to this Section 3 shall be effected without the Borrower exercising its rights under Section 2.15 of the Credit Agreement with respect to Commitment Increases.

SECTION 4. Amendment to the Credit Agreement. The Credit Agreement is hereby amended as follows:

(a) Schedule 2.01(a) of the Credit Agreement is hereby amended by replacing such schedule in its entirety with Schedule 2.01(a) attached hereto.

SECTION 5. Representations and Warranties.

To induce the other parties hereto to enter into this Amendment, the Borrower represents and warrants that, as of the date hereof:

(a) both immediately before and after giving effect to this Amendment, all representations and warranties of the Borrower contained in Article V of the Credit Agreement, and which are contained in any Loan Document furnished by the Borrower at any time under, or in connection with, this Amendment or the Credit Agreement, are true and correct, except to the extent that such representations and warranties specifically refer to a different date, in which case they are true and correct as of such date and except that the representations and warranties contained in clauses (a) and (b) of Section 5.05 of the Credit Agreement shall be deemed to refer to the most recent statements furnished pursuant to clauses (a) and (b), respectively, of Section 6.01 of the Credit Agreement;

(d) this Amendment and the Amended Credit Agreement constitute legal, valid and binding obligations of the Borrower, enforceable against the Borrower in accordance with their terms, subject as to enforcement to bankruptcy, insolvency, reorganization, moratorium and similar laws of general applicability relating to or affecting creditors’ rights and to general equity principles; and

(e) no approval, consent, exemption, authorization, or other action by, or notice to, or filing with, any Governmental Authority is required to be obtained or made by the Borrower by any material statutory law or regulation applicable to it as a condition to the execution, delivery or performance by, or enforcement against, the Borrower of this Amendment or the performance by, or enforcement against, the Borrower of the Amended Credit Agreement.
