Changes Not Requiring Approval.The
third type of change does not require any vote by holders of debt securities. This type is limited to curing any ambiguity, defect or
inconsistency, making changes to conform the provisions contained in the indenture to the description of the notes and the guarantee contained
in this prospectus or an applicable prospectus supplement and making changes that do not adversely affect the rights of holders of the
debt securities in any material respect, such as adding covenants, additional events of default or successor trustees. (Petrobras Section 9.01; PGF Section 9.01)

Further Details Concerning Voting.
When taking a vote, we will use the following rules to decide how much principal amount to attribute to a security:

| · | For original issue discount securities, we will use the principal amount that would be due and payable        
 on the voting date if the maturity of the debt securities were accelerated to that date because of a default. |

| · | Debt securities that we, any of our affiliates and any other obligor under the debt securities acquire 
 or hold will not be counted as outstanding when determining voting rights.                             |

| · | For debt securities whose principal amount is not known (for example, because it is based on an index), 
 we will use a special rule for that security described in the prospectus supplement for that security.  |

| · | For debt securities denominated in one or more foreign currencies, currency units or composite currencies,  
 we will use the U.S. dollar equivalent as of the date on which such debt securities were originally issued. |

Debt securities will not be considered outstanding,
and therefore will not be eligible to vote, if we have deposited or set aside in trust for you money for their payment or redemption.
Debt securities will also not be eligible to vote if they have been fully defeased as described under “Defeasance and Discharge.”
(Petrobras Section 14.02; PGF Section 14.02)

We will generally be entitled to set any day as
a record date for the purpose of determining the holders of outstanding debt securities that are entitled to vote or take other action
under the indenture. In limited circumstances, the trustee will be entitled to set a record date for action by holders. If we or the trustee
set a record date for a vote or other action to be taken
