On the Replacement Date, the Benchmark Replacement shall mean the sum of (x) Term SOFR and (y) 0.15% (15 basis points) for an Available Tenor of three-months’ duration. In connection with the implementation and administration of Term SOFR, Agent reserves the right to make Benchmark Replacement Conforming Changes from time to time in accordance with the Loan Agreement.

In addition, the Loan Parties have requested that Agent and Lenders amend certain terms and provisions of the Loan Agreement. In consideration of the foregoing, and for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto, intending to be legally bound, agree effective as of the date hereof that clause (i) of the definition of “Benchmark Replacement” in Section 3.8(f) of the Loan Agreement is hereby amended and restated as follows:
