(d)    Borrowings, Conversions, Continuations and Prepayments of Term SOFR Loans. In addition to any other borrowing or prepayment requirements set forth in the Credit Agreement:

(i)    Term SOFR Loans. Each Borrowing, each conversion of Loans from one Type to the other, and each continuation of Term SOFR Loans shall be made upon the Borrower’s irrevocable notice to the Administrative Agent, which may be given by (A) telephone or (B) a Committed Loan Notice; provided that any telephonic notice must be confirmed immediately by delivery to the Administrative Agent of a Committed Loan

Notice. Each such Committed Loan Notice must be received by the Administrative Agent not later than 11:00 a.m. (Eastern time) (1) two Business Days prior to the requested date of any Borrowing of, conversion to or continuation of Term SOFR Loans or of any conversion of Term SOFR Loans to Base Rate Loans. Each Borrowing of, conversion to or continuation of Term SOFR Loans shall be in a principal amount of $5,000,000 or a whole multiple of $1,000,000 in excess thereof. Each Committed Loan Notice shall specify (i) whether the Borrower is requesting a Borrowing, a conversion of Loans from one Type to the other, or a continuation of Term SOFR Loans, (ii) the requested date of the Borrowing, conversion or continuation, as the case may be (which shall be a Business Day), (iii) the principal amount of Loans to be borrowed, converted or continued, (iv) the Type of Loans to be borrowed or to which existing Loans are to be converted, and (v) if applicable, the duration of the Interest Period with respect thereto. If the Borrower fails to specify a Type of Loan in a Committed Loan Notice or if the Borrower fails to give a timely notice requesting a conversion or continuation, then the applicable Loans shall be made as, or converted to, Base Rate Loans. Any such automatic conversion to Base Rate Loans shall be effective as of the last day of the Interest Period then in effect with respect to the applicable Term SOFR Loans. If the Borrower requests a Borrowing of, conversion to, or continuation of Term SOFR Loans in any such Committed Loan Notice, but fails to specify an Interest Period, it will be deemed to have specified an Interest Period of one month.

(ii)    Conforming Changes. With respect to SOFR or Term SOFR, the Administrative Agent will have the right to make Conforming Changes from time to time and, notwithstanding anything to the contrary herein or in any other Loan Document, any amendments implementing such Conforming Changes will become effective without any further action or consent of any other party to this Agreement or any other Loan Document; provided that, with respect to any such amendment effected, the Administrative Agent shall post each such amendment implementing such Conforming Changes to the Borrower and the Lenders reasonably promptly after such amendment becomes effective.

(iii)    Committed Loan Notice. For purposes of a Borrowing of Term SOFR Loans, or a continuation of a Term SOFR Loan, the Borrower shall use the Committed Loan Notice attached hereto as Exhibit A.

(iv)    Voluntary Prepayments of Term SOFR Loans. The Borrower may, upon notice to the Administrative Agent pursuant to delivery to the Administrative Agent of a notice of loan prepayment, at any time or from time to time voluntarily prepay the Term SOFR Loans in whole or in part without premium or penalty (except as otherwise specified in the Credit Agreement); provided that such notice must be received by the Administrative Agent not later than 11:00 a.m. (Eastern time) two Business Days prior to any date of prepayment of Term SOFR Loans.

(e)    Interest.

    (i)    Subject to the provisions of the Credit Agreement with respect to default interest, each Term SOFR Loan shall bear interest on the outstanding principal amount thereof from the applicable borrowing date at a rate per annum equal to the sum of Term SOFR plus the Applicable Rate.

    (ii)    Interest on each Term SOFR Loan shall be due and payable in arrears on each Interest Payment Date applicable thereto and at such other times as may be specified in the Credit Agreement; provided, that any prepayment of any Term SOFR Loan shall be accompanied by all accrued interest on the amount prepaid, together with any additional amounts required pursuant to Section 2.10. Interest hereunder shall be due and payable in accordance with the terms hereof before and after judgment, and before and after the commencement of any proceeding under any debtor relief law.

(f)     Computations. All computations of interest for Base Rate Loans (including Base Rate Loans determined by reference to Term SOFR) shall be made on the basis of a year of 365 or 366 days, as the case may be, and actual days elapsed. All other computations of fees and interest with respect to Term SOFR Loans shall be made on the basis of a 360-day year and actual days elapsed (which results in more fees or interest, as applicable, being paid than if computed on the basis of a 365-day year). Interest shall accrue on each Loan for the day on which the Loan is made, and shall not accrue on a Loan, or any portion thereof, for the day on which the Loan or such portion is paid, provided that any Loan that is repaid on the same day on which it is made shall, subject to the provisions in the Credit Agreement addressing payments generally, bear interest for one day. Each determination by the Administrative Agent of an interest rate or fee hereunder shall be conclusive and binding for all purposes, absent manifest error.

(g)    Successor Rates. The provisions in the Credit Agreement addressing the replacement of a current Successor Rate shall be deemed to apply to Term SOFR Loans and Term SOFR, as applicable, and the related defined terms shall be deemed to include Term SOFR.
