Borrower further covenants to deliver or cause to be delivered such evidence of existence, capacity, authorization, qualification, or enforceability of its obligations as Lender may require in connection with this Amendment and the Third Modification. 8. Limitation on Interest. All agreements between Borrower and Lender, whether now existing or hereafter arising and whether written or oral, are hereby expressly limited so that in no contingency, whether by reason of acceleration of the maturity of the Notes or otherwise, shall the interest contracted for, charged, received, paid or agreed to be paid to the holder of the Notes exceed the maximum amount permissible under applicable law. If, from any circumstance whatsoever, interest would otherwise be payable to the holder of the Notes in excess of the maximum lawful amount, the interest payable to the holder of the Notes shall be reduced to the maximum amount permitted by applicable law; and if from any circumstance the holder of the Notes shall ever receive anything of value deemed interest by applicable law in excess of the maximum amount allowed by law, an amount equal to any excessive interest shall be applied to the reduction of the principal amount owing under the Notes, and not to the payment of interest, or if such excessive interest exceeds such unpaid balance of principal of the Notes, such excess shall be refunded to Borrower. All interest paid or agreed to be paid to the holder of the Notes, shall, to the extent permitted by applicable law, be amortized, prorated, allocated and spread throughout the full term of the Notes (including the period of any renewal or extension thereof) so that the interest on the Notes shall not exceed the maximum amount permitted by applicable law. This Section shall control all agreements between Borrower and the holder of the Notes. EXECUTED as of the date and year first above written.
