reflect the adoption and implementation of SOFR or any other Benchmark (as defined below) or to permit the use and administration thereof by the Bank in a manner substantially consistent with market practice or in such other manner as the Bank decides is reasonably necessary. Notwithstanding anything to the contrary herein or in any other Loan Document, any amendments implementing such technical, administrative or operational changes will become effective without any further action or consent of the Borrower. The Bank shall provide notice to the Borrower of any such amendment reasonably promptly after such amendment becomes effective. If the applicable rate under this Note is based on a Benchmark and the Bank dete1mines (which detetmination shall be final and conclusive) that (A) such Benchmark cannot be detennined pursuant to its definition other than as a result of a Benchmark Transition Event (as defined below), or (B) any enactment, promulgation or adoption of or any change in any applicable law, rule or regulation, or any change in the interpretation or administration thereof by a governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by the Bank with any guideline, request or directive (whether or not having the force oflaw) of any such authority, central bank or comparable agency shall make it unlawful or impracticable for the Bank to make or maintain or fund loans based on that Benchmark, then the Bank shall give notice thereof to the Borrower. Thereafter, until the Bank notifies the Borrower that the circumstances giving rise to such determination no longer exist, the interest rate on all amounts outstanding under this Note shall be the Alternate Rate. Notwithstanding anything to the contrary herein or in any other Loan Document, if the Bank dete1mines (which determination shall be final and conclusive) that a Benclnnark Transition Event has occurred with respect to a Benchmark, the Bank may amend this Note to replace such Benchmark with a Benchmark Replacement (as defined below); and any such amendment shall be in writing, shall specify the date that the Benchmark Replacement is effective and will not require any further action or consent of the Borrower. Until the Benchmark Replacement is effective, amounts bearing interest with reference to a Benchmark will continue to bear interest with reference to such Benclnnark as long as such Benchmark is available, and otherwise such amounts automatically will bear interest at the Alternate Rate. For purposes of this Section, the following te1ms have the meanings set forth below: "Benchmark" means, at any time, any interest rate index then used in the dete1mination of an interest rate under the terms of this Note. Once a Benchmark Replacement becomes effective under this Note, it is a Benchmark. The initial Benchmark under this Note is Daily SOFR. "Benchmark Replacement" means, for any Benchmark, the sum of (a) an alternate benchmark rate and (b) an adjustment (which may be a positive or negative value or zero), in each case that has been selected by the Bank as the replacement for such Benchmark giving due consideration to any evolving or then-prevailing market convention, including any applicable recommendations made by the official sector or any official sector-sponsored committee or working group, for U.S. dollar-denominated credit facilities at such time: provided that, if the Benchmark Replacement as determined pursuant to the foregoing would be less than the Floor, the Benchmark Replacement will be deemed to be the Floor for the purposes of this Note and the other Loan Documents. "Benchmark Transition Event" means a public statement or publication by or on behalf of the administrator of a Benchmark, the regulatmy supervisor of such administrator, the Board of Governors of the Federal Reserve System, NYFRB, an insolvency official or resolution authority with jurisdiction over the adminish·ator for such Benchmark or a comt or an entity with similar insolvency or resolution authority over the administrator for such Benchmark, announcing or stating that (a) such administrator has ceased or will cease to provide such Benchmark permanently or indefinitely, provided that at the time of such statement or publication there is no successor administrator that will continue to provide such Benchmark or (b) such Benchmark is or will no longer be representative. - 4 - Form 8C-S (COJ)- Rev. 8/23 (SOFR Rl) 123962365-3

7. Other Payment Terms. If any payment under this Note is due on a day of a calendar month for which there is no numerically corresponding day in certain other months ( each, a "Non-Conforming Month"), then the payment in a Non-Conforming Month shall be due on the last Business Day of snch Non-Conforming Month. If any payment under this Note shall become due on a day other than a Business Day, such payment shall be due on the next succeeding Business Day, except that if such day falls in the next succeeding calendar month, such payment shall be due on the next preceding day that is a Business Day. Interest shall be computed to, but excluding, the date of payment. The Borrower hereby authorizes the Bank to charge the Borrower's deposit account at the Bank for any payment when due under this Note or any other Loan Document. Payments received will be applied to charges, fees and expenses (including attorneys' fees), accrued interest and principal in any order the Bank may choose, in its sole discretion. 8. Late Payments; Default Rate. If the Borrower fails to make any payment of principal, interest or other amount coming due pursuant to the provisions of this Note within 15 calendar days of the date due and payable, the Borrower also shall pay to the Bank a late charge equal to the lesser of 5% of the amount of such payment or $100.00 (the "Late Charge"). Such 15-day period shall not be construed in any way to extend the due date of any such payment. Upon maturity, whether by acceleration, demand or otherwise, and at the Bank's option upon the occurrence of any Event of Default ( as hereinafter defined) and during the continuance thereof, amounts outstanding under this Note shall bear interest at the Default Rate. The Default Rate shall continue to apply whether or not judgment shall be entered on this Note. Both the Late Charge and the Default Rate are imposed as liquidated damages for the purpose of defraying the Bank's expenses incident to the handling of delinquent payments, but are in addition to, aud not in lieu of, the Bank's exercise of any rights and remedies hereunder, under the other Loan Documents or under applicable law, and any fees and expenses of any agents or attomeys which the Bank may employ. In addition, the Default Rate reflects the increased credit risk to the Bank of canying a loan that is in default. The Borrower agrees that the Late Charge and Default Rate are reasonable forecasts of just compensation for anticipated and actual harm incurred by the Bank, and that the actual hmm incurred by the Bank cannot be estimated with ce1tainty and without difficulty. 9. Prepayment. The indebtedness evidenced by this Note may be prepaid in whole or in part at any time without penalty. 10. Increased Costs; Yield Protection.
