 to which it is a party.                                                                   |

| · | PGF or Petrobras contests the enforceability of the debt securities of a series, the relevant indenture or the related guaranty, or 
 denies that it has liability under any of the foregoing documents to which it is a party.                                           |

| · | In the case of PGF, if Petrobras fails to retain at least 51% direct or indirect ownership of the outstanding voting and economic 
 interests (equity or otherwise) of and in PGF.                                                                                    |

| · | Any other event of default described in the applicable prospectus supplement occurs. (Petrobras Section 5.01; PGF Section 5.01) |

For these purposes, “indebtedness”
means any obligation (whether present or future, actual or contingent and including, without limitation, any guaranty) for payment on
or repayment of money that has been borrowed or raised (including money raised by acceptances and all leases which, under IFRS, would
constitute a capital lease obligation).

An event of default for a particular series of
debt securities does not necessarily constitute an event of default for any other series of debt securities issued under the indenture,
although the default and acceleration of one series of debt securities may trigger a default and acceleration of another series of debt
securities.

Remedies if an Event of Default Occurs.If
an event of default has occurred and has not been cured, the trustee or the holders of 25% in principal amount of the debt securities
of the affected series may declare the entire principal amount of all the debt securities of that series to be due and immediately payable.
This is called a declaration of acceleration of maturity. If an event of default occurs because of certain events in bankruptcy, insolvency
or reorganization, or an equivalent proceeding under the applicable law, the principal amount of all the debt securities of that series
will be automatically accelerated without any action by the trustee, any holder or any other person. A declaration of acceleration of
maturity may be canceled by the holders of at least a majority in principal amount of the debt securities of the affected series. (Petrobras Section 5.02; PGF Section 5.02)

Except in cases of default, where the trustee has
some special duties, the trustee is not required to take any action under the indenture at the request of any holders unless the holders
offer the
