Except as expressly set forth herein, this Agreement shall not be deemed to be a waiver, amendment or modification of any provisions of the Note or any right, power or remedy of the Holder, nor constitute a waiver of any provision of the Note, or any other document, instrument and/or agreement executed or delivered in connection therewith, in each case, whether arising before or after the date hereof or as a result of performance hereunder or thereunder.
