benchmark rate as a replacement to such then-current Benchmark for Dollar-denominated syndicated credit facilities and (b) the related Benchmark Replacement Adjustment; provided that, if such Benchmark Replacement as so determined would be less than the Floor, such Benchmark Replacement will be deemed to be the Floor for the purposes of this Agreement and the other Loan Documents.

“Benchmark Replacement Adjustment” means, with respect to any replacement of any then-current Benchmark with an Unadjusted Benchmark Replacement for any applicable Available Tenor (if applicable), the spread adjustment, or method for calculating or determining such spread adjustment, (which may be a positive or negative value or zero) that has been selected by the Administrative Agent and the Borrower giving due consideration to (a) any selection or recommendation of a spread adjustment, or method for calculating or determining such spread adjustment, for the replacement of such Benchmark with the applicable Unadjusted Benchmark Replacement by the Relevant Governmental Body or (b) any evolving or then-prevailing market convention for determining a spread adjustment, or method for calculating or determining such spread adjustment, for the replacement of such Benchmark with the applicable Unadjusted Benchmark Replacement for Dollar-denominated syndicated credit facilities.

Agreement is hereby amended and restated in its entirety to read as set forth on Annex I attached hereto); and (ii) to the extent permitted to be assigned under applicable law, all claims, suits, causes of action and any other right of such Assignor (in its capacity as a Lender) against any Person, whether known or unknown, arising under or in connection with the Credit Agreement and the other Loan Documents and any other documents or instruments delivered pursuant thereto or the loan transactions governed thereby or in any way based on or related to any of the foregoing, including contract claims, tort claims, malpractice claims, statutory claims and all other claims at law or in equity related to the rights and obligations sold and assigned pursuant to clause (i) above (the rights and obligations sold and assigned pursuant to clauses (i) and (ii) above being referred to herein collectively as the “Assigned Interest”; and the sales and assignments and purchases and assumptions of the Assigned Interests described in this clause (b) being referred to herein collectively as the “Assignment and Reallocation”). Such sale and assignment is without recourse to any Assignor and, except as expressly provided in this Section 3, without representation or warranty by any Assignor. Each of the Administrative Agent, each Issuing Bank, each Lender and the Borrower hereby consents and agrees to the Assignment and Reallocation. With respect to the Assignment and Reallocation, each Lender shall be deemed to have sold and assigned its Assigned Interest and each Lender shall be deemed to have acquired such Assigned Interest pursuant to the terms and conditions of the Assignment and Assumption attached as Exhibit G to the Credit Agreement (the “Assignment Agreement”), as if each Lender had executed such Assignment Agreement with respect to such Assigned Interest, pursuant to which (i) each Lender shall be an “Assignee”, (ii) each Lender shall be an “Assignor” and (iii) the term “Effective Date” shall be the Sixth Amendment Effective Date as defined herein. On the Sixth Amendment Effective Date, after giving effect to the Assignment and Reallocation, the Administrative Agent shall take the actions specified in Section 12.04(b)(iv), including recording the Assignment and Reallocation described herein in the Register, and the Assignment and Reallocation shall be effective for all purposes of the Credit Agreement. Notwithstanding anything to the contrary in Section 12.04(b)(ii)(C), no Lender shall be required to pay a processing and recordation fee of $3,500 to the Administrative Agent in connection with the Assignment and Reallocation.

4.10 No Default. As of the Sixth Amendment Effective Date, no Default shall have occurred and be continuing.
