(d)For the avoidance of doubt, (i) the loans made pursuant to the 2023 Incremental Revolving Commitments shall be deemed to be “Loans” and “Revolving Loans”, (ii) each 2023 Incremental Revolving Lender shall be deemed to be a “Lender” and a “Revolving Lender” and (iii) the 2023 Incremental Revolving Commitments shall be deemed to be a “Incremental Revolving Commitment”, a “Revolving Commitment Increase” and a “Revolving Commitment”.

(e)For the avoidance of doubt, the 2023 Incremental Revolving Commitments, and the Revolving Loans made in connection therewith, shall have the same terms as the Existing Revolving Commitments and the Revolving Loans made in connection therewith, as applicable, and shall bear interest and Commitment Fees, as applicable, as provided for in the Amended Credit Agreement with respect to Revolving Loans and Revolving Commitments, respectively. The parties hereto hereby agree that, notwithstanding anything in the Amended Credit Agreement to the contrary, the Administrative Agent is hereby authorized to take all actions as it may reasonably deem to be necessary to ensure that the 2023 Incremental Revolving Commitments constitute a Revolving Commitment Increase.

(f)This Amendment shall constitute notice to the Administrative Agent by the Borrower requesting the 2023 Incremental Revolving Commitments pursuant to Section 2.19(a) of the Credit Agreement, and, for the avoidance of doubt, shall satisfy such notice requirement set forth in Section 2.19(a) of the Credit Agreement.

(c)The execution, delivery and performance of this Amendment shall not constitute a waiver of any provision of, or operate as a waiver of any right, power or remedy of the Agent or Lender under, the Credit Agreement or any of the other Loan Documents.

(e)This Amendment is a Loan Document (as defined in the Amended Credit Agreement).

11.Expenses.

12.Severability. In the event any one or more of the provisions contained in this Amendment should be held invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein and therein shall not in any way be affected or impaired thereby (it being understood that the invalidity of a particular provision in a particular jurisdiction shall not in and of itself affect the validity of such provision in any other jurisdiction). The parties shall endeavor in good-faith negotiations to replace the invalid, illegal or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the invalid, illegal or unenforceable provisions.

13.Headings. Section headings used herein are for convenience of reference only, are not part of this Amendment and shall not affect the construction of, or to be taken into consideration in interpreting, this Amendment.
