Reference is hereby made to the Revolving Credit Agreement dated as of September 29, 2025 (as amended, restated, amended and restated, supplemented or otherwise modified from time to time, the “Revolving Credit Agreement”), by and among the Company, the other Borrowers and Guarantors from time to time party thereto, the Banks from time to time party thereto and the Administrative Agent. Capitalized terms used but not otherwise defined herein shall have the meanings assigned to them in the Revolving Credit Agreement. This Agreement shall be a “Loan Document” for all purposes of the Revolving Credit Agreement and the other Loan Documents.

Pursuant to Section 2.21(a) of the Revolving Credit Agreement, the Company has requested, and each Increasing Bank has agreed, to increase (x) the Commitment of each Increasing Bank under the Revolving Credit Agreement as set forth on Schedule 1 hereto and as otherwise set forth herein and (y) the Aggregate Commitments under the Revolving Credit Agreement from $3,000,000,000 to $4,000,000,000 (collectively, the “Commitment Increase”), in each case subject to the terms and conditions set forth herein.

Accordingly, each Increasing Bank, the Company, each other Credit Party party hereto and the Administrative Agent agree as follows:

(b) this Agreement constitutes such Credit Party’s valid and binding agreement and, when executed and delivered in accordance with this Agreement, will constitute the valid and binding obligations of such Credit Party, in each case enforceable in accordance with its terms, except as may be limited by (i) bankruptcy, insolvency or other similar laws affecting the rights and remedies of creditors generally, (ii) general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law) and (iii) implied covenants of good faith and fair dealing;

(d) the representations and warranties contained in Article 4 of the Revolving Credit Agreement are true and correct in all material respects on and as of such date as if made on and as of such date (except (i) where such representations and warranties expressly relate to an earlier date, in which case such representations and warranties shall have been true and correct in all material respects as of such earlier date and (ii) any representation or warranty that is qualified as to materiality or “Material Adverse Effect” shall be true and correct in all respects).
