(which may be a SOFR-Based Rate) that has been selected by the Administrative Agent and the Borrower giving due consideration to (i) any selection or recommendation of a replacement rate or the mechanism for determining such a rate by the

announcing that the LIBO Screen Rate is no longer representative.

(a) the rate, or methodology for this rate, and conventions for this rate selected or recommended by the Relevant Governmental
Body for determining compounded SOFR; provided that:
