CLAUSE 15.

Paragraph One. The parties acknowledge on this occasion that the occurrence of any hindrance to use of resources held abroad or remittances abroad by the DEBTOR of funds in foreign currency is a predictable event, with foreseeable financial and economic consequences, regardless of its cause.

obtaining all necessary approvals, in particular, that of Banco Central do Brasil, complying with the applicable regulatory periods, and payment by the DEBTOR to the LENDER of the principal and interest accrued as of the date of early settlement, considering the interest rate originally agreed upon, and taxes as the result of early settlement.

CLAUSE 23. Compensation of amounts -- Noncompliance with any obligation of the DEBTOR arising under this Contract entitles the LENDER to move for immediate execution of this Contract and the collateral in this Contract as well as other rights that it may generate.

The advance payment provided in this Clause will be made without premium, but with the interest accrued on the Loans up to the date of prepayment and all other amounts then payable to the LENDER under this Contract, including those provided in Clause 20.

CLAUSE 25. Abstention by the LENDER from exercising any rights or powers to which it is entitled as a result of law or this Contract, or any Contract with delays in meeting the obligations here assumed by the DEBTOR, will not imply renewal nor impede the LENDER from exercising such duties and powers at any time.
