Interest.





(a) The Borrower shall pay to each Lender, in respect of each Interest Period and without need for demand, interest on the outstanding principal amount of the Loans made available by such Lender, at an annual rate equal to the TIIE for the relevant Interest Period plus the Applicable Margin (the “Interest Rate”).

(a) If any amount due and payable under the Amended and Restated Credit Agreement or the Promissory Notes is not paid when due, such amount shall accrue late interest from the date on which it became due to the date on which it shall have been paid in full, at an annual rate equal to the Interest Rate for the relevant period, multiplied by two (2) (the “Late Interest Rate”).





(b) The daily amount of late interest accrued by any past due amount shall be determined by multiplying such amount by the quotient of dividing the Late Interest Rate by 360 (three hundred sixty), which late interest shall be due and payable on demand by the Borrower based on the actual number of days elapsed and for so long as a default shall have occurred and be continuing.





Repayment.





(a) The Borrower shall repay to each Lender the principal outstanding portion of Tranche 1 funded by such Lender in 72 (seventy-two) consecutive monthly installments, each in an amount equal to the product of multiplying the disbursed amount of Tranche 1 by the percentage set forth in the schedule as with respect to the relevant Payment Date, beginning on the Payment Date immediately following the Effective Date of the Amended and Restated Credit Agreement (the last such date, the “Tranche 1 Maturity Date”).

If the prepaid amount shall be equal to or less than $50,000,000 (fifty million Dollars) or its equivalent in any other currency, 50% (fifty percent) of such amount shall be allocated to repay Tranche 1 and the remaining 50% (fifty percent) shall be allocated to repay Tranche 2, on a pro rata basis taking into consideration the outstanding amount of the Loans funded by each Lender. If the prepaid amount shall exceed 50,000,000 (fifty million Dollars) or its equivalent in any other currency, the Borrower shall have the right to determine the percentage of such amount that shall be allocated to repay the Loans, or to repay Tranche 1 or Tranche 2.
