Any failure by Beneficiary to insist upon the strict performance by Grantor of any of the terms and provisions of any of the Documents shall not be deemed to be a waiver of any of the terms and provisions of any of the Documents; and Beneficiary, notwithstanding any such failure, shall have the right thereafter to insist upon the strict performance by Grantor of any and all of the terms and provisions of each of the Documents. The acceptance by Beneficiary of any sum after any Default or Event of Default shall not constitute a waiver of the right to require prompt performance of all of the covenants and conditions contained in any of the Documents. The acceptance by Beneficiary of any sum less than the sum then due shall be deemed an acceptance on account only and shall not constitute a waiver of the obligation of Grantor to pay the entire sum then due. Grantor's failure to pay said entire sum due shall be and continue to be an Event of Default notwithstanding such acceptance of such lesser amount on account and Beneficiary shall be entitled to exercise all rights conferred upon it following a Default or Event of Default notwithstanding such acceptance.
