The Payee may demand payment of the unpaid principal of this Note in whole or in part at any time. In the event the Payee shall demand payment in connection with a prepayment of the Term Loan which, pursuant to the Credit Agreement, requires a prepayment premium, fee or breakage cost payment, the Payor shall pay a premium, fee or breakage cost payment, as the case may be, on the principal amount repaid in an amount equal to the amount of such premium, fee or breakage cost payment under the Credit Agreement.

No failure or delay on the part of the Payee in exercising any of its rights, powers or privileges hereunder shall operate as a waiver thereof, nor shall a single or partial exercise thereof preclude any other or further exercise of any right, power or privilege.

conflict herewith. In the event that the Payee shall collect monies which are deemed to constitute interest which would increase the effective interest rate on this Note to a rate in excess of that permitted to be charged by applicable law, all such sums deemed to constitute interest in excess of the lawful rate shall, upon such determination, at the option of the Payee, be either immediately returned to the Payor or credited against the principal balance of this Note then outstanding, in which event any and all penalties of any kind under applicable law as a result of such excess interest shall be inapplicable.

The Payee may assign this Note without the consent of the Payor. The Payor may not assign any of its rights and obligations under this Note without the prior written consent of the Payee. Any assignment made in violation of the foregoing prohibition shall be void.
