The Borrowers and Holdings have requested that the Credit Agreement be amended (i) to provide for new term loans (the “2017 Term Loans”) to be made to the Borrowers in an aggregate principal amount of $3,185,593,272.72 and having the terms set forth herein and as otherwise set forth for Term Loans under the Credit Agreement (after giving effect to the amendments thereto provided for herein), the proceeds of which will be used by the Borrowers, together with cash on hand of the Borrowers, if necessary, to prepay in full all outstanding Existing Term Loans, to pay all accrued and unpaid interest thereon and to pay all fees and expenses incurred in connection with the foregoing and (ii) as otherwise set forth herein.

D. Pursuant to Section 2.18 of the Credit Agreement, the Borrowers may obtain Specified Refinancing Term Loans by, among other things, entering into a Refinancing Amendment in accordance with the terms and conditions of the Credit Agreement.

provided, however, that the final principal repayment installment of the Initial Term Loans shall be repaid on the Maturity Date for the Initial Term Loans and in any event shall be in an amount equal to the aggregate principal amount of all Initial Term Loans outstanding on such date.

(k) Section 3.08(c) of the Credit Agreement is hereby amended by replacing the reference to “the Closing Date” therein with “the Amendment No. 3 Effective Date”.

SECTION 3. Loans.

(a) Subject to the terms and conditions set forth herein and in the Credit Agreement, (i) each person designated as a “Term Lender” on Schedule I hereto (each, a “2017 Term Lender”) agrees, severally and not jointly, to make a 2017 Term Loan to the Borrowers on the Amendment No. 3 Effective Date (as defined below) in an aggregate principal amount not to exceed the amount set forth opposite its name on Schedule I hereto, and (ii) from and after the making of the 2017 Term Loans on the Amendment No. 3 Effective Date, (x) each 2017 Term Loan shall be a “Term Loan” and a “Loan” and, unless the context requires a reference solely to the Term Loans made prior to the Amendment No. 3 Effective Date, an “Initial Term Loan” (for the avoidance of doubt, the Maturity Date for the 2017 Term Loans shall be the same as the Maturity Date for the Initial Term Loans made prior to the Amendment No. 3 Effective Date), (y) each Person that holds 2017 Term Loans from time to time shall be a “Term Lender” and a “Lender”, and (z) the aggregate 2017 Term Loans of all Persons that hold 2017 Term Loans shall be the “Term Facility”, in each case, for all purposes under the Credit Agreement (as amended hereby) and the other Loan Documents. Without limiting the foregoing, the Borrowers hereby unconditionally promise to repay the 2017 Term Loans in accordance with the schedule of installment payments set forth in Section 2.07(a) of the Credit Agreement (after giving effect to the amendments thereto effected hereby and as the same may be further adjusted in accordance with the Credit Agreement). Amounts borrowed as 2017 Term Loans and subsequently repaid may not be reborrowed. The proceeds of the 2017 Term Loans shall be used by the Borrowers solely to make the Loan Repayment (as defined below). For the avoidance of doubt, the making of the 2017 Term Loans hereunder shall constitute “Specified Refinancing Debt” within the meaning of Section 2.18 of the Credit Agreement.

5

(b) On the Amendment No. 3 Effective Date, (i) the Borrowers shall prepay in full all Existing Term Loans outstanding under the Credit Agreement, together with all accrued and unpaid interest thereon and all fees and expenses incurred in connection with the foregoing, with the proceeds of the 2017 Term Loans and, if necessary, cash on hand of the Borrowers (collectively, the “Loan Repayment”). Notwithstanding the making of the Loan Repayment, the holders of the Existing Term Loans shall thereafter continue to be entitled to the benefits of Sections 3.01, 3.03, 3.04, 3.05, 3.06 and 10.04 of the Credit Agreement as in effect immediately prior to the Amendment No. 3 Effective Date and shall continue to be bound by Section 9.07 of the Credit Agreement as in effect immediately prior to the Amendment No. 3 Effective Date.

SECTION 4. Representations and Warranties. The Borrowers hereby represent and warrant, on the date hereof and as of the Amendment No. 3 Effective Date (both before and after giving effect to the making of the 2017 Term Loans) that:

(a) no Default or Event of Default exists, both before and after giving effect to this Amendment and the making of the 2017 Term Loans, or would result from the application of the proceeds of the 2017 Term Loans;

(b) the representations and warranties of the Borrowers and each other Loan Party contained in Article V of the Credit Agreement or in any other Loan Document are true and correct in all material respects (and in all respects if any such representation or warranty is already qualified by materiality), both before and after giving effect to this Amendment, except to the extent that any such representation or warranty specifically refers to an earlier date, in which case such representation or warranty was true and correct in all material respects (and in all respects if any such representation or warranty is already qualified by materiality) as of such earlier date (and except that, for purposes of this clause (b), the representations and warranties contained in Sections 5.05(a) and 5.05(b) of the Credit Agreement shall be deemed to refer to the most recent financial statements furnished pursuant to Section 6.01(a) and (b), respectively, of the Credit Agreement prior to the Amendment No. 3 Effective Date);

(c) this Amendment has been duly authorized, executed and delivered by the Borrowers and each other Loan Party, and this Amendment constitutes a legal, valid and binding obligation of the Borrowers and each other Loan Party, enforceable against the Borrowers and each other Loan Party in accordance with its terms, except as such enforceability may be limited by bankruptcy, insolvency, reorganization, receivership, moratorium or other laws affecting creditors’ rights generally and by general principles of equity; and

(d) after giving effect to the making of the 2017 Term Loans and the Loan Repayment, the Borrowers and their Subsidiaries, on a consolidated basis, are Solvent.

6

SECTION 5. Amendment Effectiveness. The effectiveness of the amendments to the Credit Agreement contemplated hereby and the obligations of each 2017 Term Lender to make any 2017 Term Loans hereunder shall be subject to the satisfaction (or waiver by each 2017 Term Lender party hereto), on or prior to the May 30, 2017, of the following conditions (the first Business Day on which all conditions are so satisfied or waived and the 2017 Term Loans are made, the “Amendment No. 3 Effective Date”):

(c) the Administrative Agent shall have received (i) such documents and certifications (including Organization Documents and, to the extent available under applicable local law, good standing certificates) as the Administrative Agent may reasonably require to evidence that Holdings, the Borrowers and each Subsidiary Guarantor is duly organized or formed, and that each of them is validly existing, and, to the extent available under local law, in good standing and qualified to engage in business in each jurisdiction where its ownership, lease or operation of properties or the conduct of its business requires such qualification, except to the extent that failure to be so qualified could not reasonably be expected to have a Material Adverse Effect;

(d) the Administrative Agent shall have received a Committed Loan Notice relating to the incurrence of the 2017 Term Loans;

(f) the Administrative Agent shall have received an opinion of (i) Latham & Watkins LLP, special New York, Delaware, Texas and California counsel to the Loan Parties, and (ii) Herbert Smith Freehills LLP, United Kingdom counsel to the Administrative Agent and each 2017 Term Lender, in each case in form and substance reasonably satisfactory to the Administrative Agent;

7

(h) subject to Section 6 of this Amendment, all actions or documents reasonably requested by the Administrative Agent that are necessary to establish or re-affirm that the Collateral Agent will have a perfected first priority security interest (subject to Liens permitted under Section 7.02 of the Credit Agreement) in the Collateral to secure the 2017 Term Loans shall have been taken or executed and delivered (including, if so requested, deeds of confirmation, amendments and/or supplements to Collateral Documents);

(i) the Administrative Agent and its affiliates shall have received from the Borrowers (or shall be satisfied that it will receive substantially concurrently with the effectiveness of this Amendment) immediately available funds in an amount sufficient to consummate the Loan Repayment and pay all other fees and reimburse all expenses separately agreed in writing by the Borrowers and any 2017 Term Lender or required by Section 10.04 of the Credit Agreement or by any other Loan Document to be paid by the Borrowers in connection with this Amendment and the transactions contemplated hereby (to the extent, in the case of reimbursement of expenses, invoiced in reasonable detail on or prior to the date hereof);

(j) the representations and warranties set forth in Section 4 above shall be true and correct, and no Default or Event of Default shall exist before or after giving effect to the transactions contemplated hereby (and the Administrative Agent shall have received a certification by a Responsible Officer of each Borrower that the condition specified in this clause (j) have been satisfied); and

(k) substantially concurrently with the effectiveness of this Amendment, the 2017 Term Loans shall have been made.

SECTION 6. Real Estate Collateral.

8

the liens of the Mortgages as amended; provided that if and to the extent that on or prior to the Amendment No. 3 Effective Date the Borrowers deliver to the Collateral Agent (x) an opinion of local counsel in form and substance reasonably acceptable to the Collateral Agent affirming that no amendment to an existing Mortgage is necessary for such Mortgage to remain in full force and effect and to secure the Obligations, as modified by the transactions contemplated by this Amendment, as well as (y) a title report (or title update) showing no Liens, other than Liens permitted by the applicable Mortgage, have arisen with respect to such property since the date of the latest title policy or date-down endorsement, then the Collateral Agent will accept such deliveries in lieu of the requirements set forth in clauses (a) through (d) of this sentence with respect to such property. All of the actions referenced above shall be taken, and documents referenced above shall be delivered, at the sole expense of the Borrowers, including any recording charges, taxes, or other associated costs related thereto.

SECTION 7. Effect of Amendment. Except as expressly set forth herein, this Amendment shall not by implication or otherwise limit, impair, constitute a waiver of, or otherwise affect the rights and remedies of the Lenders, the L/C Issuers or the Administrative Agent under the Credit Agreement or any other Loan Document, and shall not alter, modify, amend or in any way affect any of the terms, conditions, obligations, covenants or agreements contained in the Credit Agreement or any other Loan Document, all of which are ratified and affirmed in all respects and shall continue in full force and effect. Nothing herein shall be deemed to entitle any Loan Party to a consent to, or a waiver, amendment, modification or other change of, any of the terms, conditions, obligations, covenants or agreements contained in the Credit Agreement or any other Loan Document in similar or different circumstances. This Amendment shall apply and be effective only with respect to the provisions of the Credit Agreement specifically referred to herein. After the Amendment No. 3 Effective Date, any reference to the Credit Agreement in any Loan Document, and the terms “this Agreement”, “herein”, “hereunder”, “hereto”, “hereof”, “hereby” and words of similar import in the Credit Agreement, shall, unless the context otherwise requires, mean the Credit Agreement as modified hereby. This Amendment shall constitute a “Refinancing Amendment” and a “Loan Document” for all purposes of the Credit Agreement and the other Loan Documents. This Amendment shall not extinguish the Obligations for the payment of money outstanding under the Credit Agreement (except as otherwise expressly provided with respect to the Loan Repayment) or discharge or release the Lien of any Loan Document or any other security therefor or any guarantee thereof, and the Liens and security interests in favor of the Administrative Agent for the benefit of the Secured Parties securing payment of the Obligations are in all respects continuing and in full force and effect with respect to all Obligations. Nothing herein contained shall be construed as a substitution or novation, or a payment and reborrowing, or a termination, of the Obligations outstanding under the Credit Agreement or instruments guaranteeing or securing the same (except as otherwise expressly provided with respect to the Loan Repayment), which shall remain in full force and effect, except as modified hereby or by instruments executed concurrently herewith.

9

SECTION 8. Acknowledgement and Consent. Each Loan Party hereby acknowledges that it has read this Amendment and consents to the terms hereof and further hereby affirms, confirms and agrees that (a) notwithstanding the effectiveness of this Amendment, the obligations of such Loan Party under each of the Loan Documents to which

it is a party shall not be impaired and each of the Loan Documents to which such Loan Party is a party is, and shall continue to be, in full force and effect and is hereby confirmed and ratified in all respects, in each case, as amended hereby; and (b) its Guarantee of the Obligations, and the pledge of and/or grant of a security interest in its assets as Collateral to secure the Obligations, all as and to the extent provided in the Collateral Documents as originally executed, shall continue in full force and effect in respect of, and to secure, the Obligations (including, without limitation, the 2017 Term Loans) and shall accrue to the benefit of the Secured Parties (including the holders of 2017 Term Loans). Without limiting the foregoing, as security for the payment or performance, as the case may be, in full of the Obligations, each Loan Party hereby grants to the Collateral Agent, for the ratable benefit of the Secured Parties, a security interest in all right, title and interest now owned or at any time hereafter acquired in the Collateral (as defined in each Collateral Document).

SECTION 9. Counterparts. This Amendment may be executed in one or more counterparts (and by different parties hereto in different counterparts), each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. Delivery by telecopier or other electronic transmission of an executed counterpart of a signature page to this Amendment shall be effective as delivery of an original executed counterpart of this Amendment. The Administrative Agent may also require that any such documents and signatures delivered by telecopier or other electronic transmission be confirmed by a manually-signed original thereof; provided that the failure to request or deliver the same shall not limit the effectiveness of any document or signature delivered by telecopier or other electronic transmission.

SECTION 10. Governing Law; Jurisdiction; Etc. The provisions of Sections 3.06, 10.15 and 10.17 of the Credit Agreement shall apply to this Amendment, mutatis mutandis.

SECTION 11. Headings. The headings of this Amendment are for purposes of reference only and shall not limit or otherwise affect the meaning hereof.
