Interest on this Note shall be due and payable in accordance with the Loan Agreement. The unpaid principal balance of this Note, together with all unpaid interest accrued hereon, shall be due and payable in full on the Revolving Commitment Termination Date.

All payments under this Note shall be applied first to unpaid accrued interest and then to outstanding principal.

Upon the occurrence of any Event of Default specified in Section 7.01(f) of the Loan Agreement, the entire unpaid principal and accrued and unpaid interest hereunder and all other outstanding indebtedness evidenced hereby will become immediately due and payable, without notice or demand. If any other Event of Default specified in the Loan Agreement shall occur, the Lender may, at its option, without notice or demand, declare the entire unpaid principal and accrued and unpaid interest hereunder and all other outstanding indebtedness evidenced hereby to be immediately due and payable, whereupon the same shall become forthwith due and payable.

This Note is made, executed and delivered pursuant to the Loan Agreement and is one of promissory notes described therein.

To the extent any payment due hereunder is not paid within 10 calendar days of the applicable due date, the Borrowers shall pay to the Lender a late fee equal to 5% of the amount of the payment that was to have been made. The Borrowers agree that such late fee is reasonable compensation to the Lender for the acceptance and handling of such late payments.

The Borrowers hereby waive presentment for payment, demand, notice of nonpayment, protest and notice of protest with respect to any payment hereunder and agree to any extension of time with respect to any payment due hereunder and to the addition or release of any party liable hereunder. No delay on the part of the holder hereof in exercising any rights hereunder shall operate as a waiver of such rights.

Upon the occurrence of any Event of Default, the Lender shall have the right, immediately and without further action by it, to set off against this Note all money owed by the Lender in any capacity to the Borrowers or any guarantor, endorser or other person who is or may be liable for payment hereof, whether or not due, and also to set off against all other liabilities of the Borrowers or other such person to the Lender all money owed by the Lender in any capacity to the Borrowers or other such person; and the Lender shall be deemed to have exercised such right of setoff and to have made a charge against such money immediately upon the occurrence of such Event of Default even though such charge is made or entered into the books of the Lender subsequently thereto.

This Note is made, executed and delivered by the Borrowers and accepted by the Lender in reaffirmation, modification and replacement of and substitution for, but not in novation, discharge or extinguishment of, that certain Promissory Note dated November 24, 2021, made by the Borrowers payable to the order of the Lender in the stated principal amount of $100,000,000.00.
