Interest

Other Fees

In addition to interest and principal payments, the Borrower shall be required to reimburse BNDES for any income tax it must pay with respect to funds raised by BNDES in a foreign currency.

All outstanding amounts borrowed in foreign currency through the agreement shall be adjusted daily to reflect exchange rate variations of the real against such foreign currency using different foreign exchange indexes depending on the type of credit line granted .

Term, Method of Payment and Separate Agreements

The term and amounts of each line of credit to be executed under the agreement shall be established in separate agreements. However, in no case may such term exceed 120 months and all payments of principal need to be made on a monthly basis after the grace period (if any) ends. In addition, the separate agreements need to specify the main terms and conditions of the loan, including, but not limited to, the purpose of the loan, and the execution of such agreements will be conditioned on compliance with the law and submission of relevant documentation by the Borrower.

The terms and conditions for credits in local currency withdrawn from certain federal funds may change if amendments are made to the laws governing such funds.

In the event BNDES is required to use judicial means to recover any outstanding credits (including other charges), an additional 10% fee shall be imposed on such amounts in addition to all fees associated with the judicial proceeding.
