DESCRIPTION OF THE GUARANTIES</div>

The following description of the terms and provisions
of the guaranties summarizes the general terms that will apply to each guaranty that Petrobras will deliver in connection with an issuance
of debt securities or debt warrants by PGF. When PGF sells a series of its debt securities or debt warrants, Petrobras will execute and
deliver a full and unconditional guaranty of that series of debt securities or debt warrants for the benefit of the holders of that series
of debt securities or debt warrants. You should read the more detailed provisions of the applicable guaranty, including the defined terms,
for provisions that may be important to you. This summary is subject to, and qualified in its entirety by reference to, the provisions
of such guaranty.

Pursuant to any guaranty, Petrobras will agree,
from time to time upon the receipt of notice from the trustee that PGF has failed to make the required payments under a series of debt
securities and the PGF indenture or under the debt warrants and the PGF debt warrant agreement, to indemnify you for unpaid claims against
PGF, whether those claims are in respect of principal, interest or any other amounts. The amount to be paid by Petrobras under the guaranty
will be an amount equal to the amount of those claims plus interest and any applicable premium and additional amounts thereon from the
date PGF was otherwise obligated to make its payments under the PGF indenture to the date Petrobras actually makes payment under the guaranty.
Petrobras will be obligated to make these payments by the expiration of any applicable grace periods under the PGF indenture and the applicable
terms of the debt securities or debt warrants. Petrobras may have the right to defer its obligation under the guaranty to make payments
under certain circumstances described in the applicable prospectus supplement.

Only one guaranty will be issued by Petrobras in
connection with the issuance of a series of debt securities or debt warrants by PGF. Unless the applicable prospectus supplement states
otherwise, The Bank of New York Mellon will act as guaranty trustee under each guaranty.

A guaranty may include certain covenants and other
provisions relating to Petrobras. The description of the applicable guaranty in the prospectus supplement will summarize the material
provisions thereof and reference will be made to the guaranty.
