Optional Tax Redemption

Unless otherwise indicated in a prospectus supplement,
we may have the option to redeem, in whole but not in part, the debt securities where, as a result of a change in, execution of or amendment
to any laws or treaties or the official application or interpretation of any laws or treaties, we would be required to pay additional
amounts as described later under “Payment of Additional Amounts.” This applies only in the case of changes, executions or
amendments that occur on or after the date specified in the prospectus supplement for the applicable series of debt securities and in
the jurisdiction where we are incorporated or organized. If succeeded by another entity, the applicable jurisdiction will be the jurisdiction
in which such successor entity is incorporated or organized, and the applicable date will be the date the entity became a successor. (Petrobras Section 11.08; PGF Section 11.08)

If the debt securities are redeemed, the redemption
price for debt securities (other than original issue discount debt securities) will be equal to the principal amount of the debt securities
being redeemed plus accrued interest and any additional amounts due on the date fixed for redemption. The redemption price for original
issue discount debt securities will be specified in the prospectus supplement for such securities. Furthermore, we must give you between
30 and 60 days’ notice before redeeming the debt securities.

Conversion

Your debt securities may be convertible into or
exchangeable for shares of Petrobras’ capital stock at your option or at our option, which may be represented by ADSs, or other
securities if the applicable prospectus supplement so provides. If your debt securities are convertible or exchangeable, the prospectus
supplement will include provisions as to whether conversion or exchange is at your option or at our option. The prospectus supplement
would also include provisions regarding the adjustment of the number of securities to be received by you upon conversion or exchange.

<div align='center'>Payment of Additional Amounts</div>

Except as provided below and under the applicable
prospectus supplement, PGF or Petrobras, as applicable, will make all payments of amounts due under the debt securities and the indenture
and each other document entered into in connection with the debt securities
