The underwriters and their
affiliates have engaged in, and may in the future engage in, investment banking and other commercial dealings in the ordinary course of
business with Petrobras, PGF and their affiliates. They have received, or may in the future receive, customary fees and commissions for
these transactions.

In addition, in the ordinary course of their business activities, the underwriters and their affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers. Such investments and securities activities may involve securities and/or instruments of ours or our affiliates. If any of the underwriters or their affiliates has a lending relationship with us, certain of those underwriters or their affiliates routinely hedge, and certain other of those underwriters or their affiliates may hedge, their credit exposure to us consistent with their customary risk management policies. Typically, these underwriters and their affiliates would hedge such exposure by entering into transactions which consist of either the purchase of credit default swaps or the creation of short positions in our securities, including potentially the Notes offered hereby. Any such credit default swaps or short positions could adversely affect future trading prices of the Notes offered hereby. The underwriters and their affiliates may also make investment recommendations and/or publish or express independent research viewsin respect of such securities or financial instruments and
may hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

The underwriters and/or their
affiliates may acquire the Notes for their own accounts. Such acquisitions may have an effect on demand for and the price of the Notes.

The expenses of the offering, excluding the underwriting discount,
are estimated to be U.S.$1.2 million and will be borne by PGF. PGF has agreed to reimburse the underwriters for certain of their expenses
relating to the offering, including the fees and disbursements of counsel to the underwriters. Such reimbursement is deemed underwriting
compensation by the Financial Industry Regulatory Authority Inc. (FINRA).

Petrobras has been advised by the underwriters that they propose to offer
