Any amounts received by Lender under this Note and turned over to holders of Senior Debt under this Section shall be reinstated as owing to Lender. 19 2 (D) Except to the extent provided in this Section, nothing contained in this Note shall impair, as between the Borrower and the Lender, the obligation of the Borrower to pay to Lender the principal amount of this Note, interest on such amount and collection costs, if any, as and when the same shall become due and payable in accordance with the terms of this Note, or prevent Lender from exercising all rights, powers and remedies otherwise permitted by applicable law or under this Note, all subject to the rights of the holders of the Senior Debt under this Section.
