6. Amendments. This Note may not be modified, amended, waived, extended, changed, discharged or terminated orally or by any act or failure to act on the part of Borrower or Lender, but only by an agreement in writing signed by the party against whom enforcement of any modification, amendment, waiver, extension, change, discharge or termination is sought. Whenever used, the singular number shall include the plural, the plural the singular, and the words “Lender” and “Borrower” shall include their respective successors, assigns, heirs, executors and administrators.

The obligation of Borrower to make the payments provided for in this Note are absolute and unconditional and not subject to any defense, set-off, counterclaim, rescission, recoupment or adjustment whatsoever.

8. Usury Compliance. This Note subject to the express condition that at no time shall Borrower be required to pay interest on the Principal Sum at a rate which could subject Lender to either civil or criminal liability as a result of being in excess of the Maximum Legal Rate. If by the terms of this Note, Borrower is at any time required or obligated to pay interest on the outstanding Principal Sum at a rate in excess of the Maximum Legal Rate, the interest rate shall be deemed to be immediately reduced to the Maximum Legal Rate and all previous payments in excess of the Maximum Legal Rate shall be deemed to have been payments in reduction of principal and not on account of the interest due hereunder. All sums paid or agreed to be paid to Lender for the use, forbearance, or detention of the sums due under this Note, shall, to the extent permitted by applicable law, be amortized, prorated, allocated and spread throughout the full stated term of this Note until payment in full so that the rate or amount of interest paid by Borrower to Lender on account of this Note does not exceed the Maximum Legal Rate from time to time in effect and applicable to this Note for so long as any portion of the Principal Sum remains outstanding.

9. Notices. All notices, demands, requests, consents, waivers, approvals or other communications required, permitted or desired to be given hereunder shall be in writing and shall be sent by registered or certified mail, postage prepaid, return receipt requested, or delivered by hand or by reputable overnight courier, addressed to the party to be so notified at its address hereinafter set forth, or to such other address as such party may hereafter specify in accordance with the provisions of this Section 9.
