(a) Interest. Accrued interest on this Note shall be payable at maturity. 

(b) Voluntary Prepayment. This Note may be prepaid, in whole or in part, at any time without penalty. Any permitted prepayment of this

the amount of prepayment exceeds the amount of all such expenses and accrued interest, to the payment of principal of this Note. Any partial payment of principal of this Note shall be documented by appropriate amending and updating of the Schedule
of Amounts Drawn. 
 (c) Mandatory Prepayment. The outstanding principal amount of this Note, plus all accrued and unpaid interest,
shall be due and payable in the event of a Change of Control, immediately prior to the closing of such Change of Control. For clarity, the amounts due pursuant to this Section 1(c) shall be paid prior to the payment of any amounts
