In case none of the aforementioned rates are published, the parties agree to the execution of an amendment agreement for this Agreement, with the purpose of establishing the interest rate applicable to the same. The foregoing, within a term no greater than 30 (thirty) calendar days notifies the Borrower of said circumstance.

“Libor Rate” (London Interbank Offered Rate), means the annual interest rate offered by the principle Banks in the interbank London market as the rate for Dollar deposits for a 30 day period, approximately at 11:00 (London, England time), that appears published 48 (forty eight) hours before the Beginning of each Interest Period in the page LIBOR 01 OF THE REUTERS INFORMATION SYSTEM, OR ALSO ON THE BTMM PAGE OF THE BLOOMBERG SYSTEM, both for the deposit in United States of America Dollars, or those to substitute, in case such pages were no longer published.

Said rate will be rounded to, if it were to be presented even in 1/100,000, or more than a percentage point, the 1/10,000 of the nearest percentage point. To this effect, five 1/100,000 of a point are considered nearer the 1/10,000 of the immediately superior percentage point.

In case the aforementioned rate is not published, the Bank and the Borrower agree to execute an amendment agreement to this Agreement, with the purpose of establishing the interest rate applicable to the same. The foregoing would be executed within a 30 (thirty) calendar day term, to the date on which the Bank notifies the Borrower of said circumstance.

If the parties do not reach an agreement with respect to the substitute rate applicable within the agreed upon, this will be considered cause for early maturity of this Agreement, in which case the Borrower will have to pay the Bank the unpaid Credit balance and its additional charges, on the date of said maturity, every time that on the contrary the unpaid balance accrues default interests pursuant to what was agreed-upon herein, taking as a basis the last ordinary applicable rate to the present Agreement.

To calculate the ordinary interests for each Interest Period, the annual applicable interest rate will be divided by 360 (THREE HUNDRED AND SIXTY) and the result will be multiplied by the number of calendar days that constitute the Interest Period at hand. The resulting rate will be multiplied by the unpaid balance of the Credit and the product will be the quantity that by virtue of interests the Borrower will have to pay the Bank on each Interest Payment Date.

DEFAULT INTERESTS.

EIGHTH. In case the Borrower does not pay punctually an amount it must cover in favor of the Bank in accordance to this Agreement, excepting interests, said amount will accrue default interests as of the date of its maturity until it is completely paid, interests that will accrue daily, that will be paid immediately and in accordance to an annual rate equal to the ordinary interests rate, plus 2 (two) percentage points.

To calculate default interests, the annual applicable default interest rate will be divided by 360 (THREE HUNDRED AND SIXTY) and the quotient will be applied to the unpaid and matured balances, thus resulting the default interest for each day, which the Borrower has agreed to pay in the terms of this Agreement.
