 and 839 of the Brazilian Civil Code, under article 794,
caput, of the Brazilian Civil Procedure Code) upon failure of PGF to make, at the maturity date of the Notes or earlier upon any acceleration
or otherwise of the applicable Notes in accordance with the terms of the indenture, any payment in respect of principal, interest or other
amounts due under the relevant indenture and the Notes of any series on the date any such payment is due. If PGF fails to make payments
to the trustee in respect of the guaranteed obligations, Petrobras will, upon notice from the trustee, immediately pay to the trustee
such amount of the guaranteed obligations payable under the indenture and the Notes. All amounts payable by Petrobras under the guaranties
will be payable in U.S. dollars and in immediately available funds to the trustee. Petrobras will not be relieved of its obligations under
any guaranty unless and until the trustee receives all amounts required to be paid by Petrobras under such guaranty (and any related event
of default under the relevant indenture has been cured), including payment of the total non-payment overdue interest.

Events of Default

There are no events of default
under the guaranties. The seventh supplemental indenture and the eighth supplemental indenture, however, contain events of default relating
to Petrobras that may trigger an event of default and acceleration of the 20 Notes or the 20 Notes. See “Description of the Notes—Events
of Default.” Upon any such acceleration (including any acceleration arising out of the insolvency or similar events relating to
Petrobras), if PGF fails to pay all amounts then due under the 20 Notes or the 20 Notes, as applicable, and the relevant indenture, Petrobras
will be obligated to make such payments pursuant to the relevant guaranty.

Covenants

20 Notes or the 20 Notes, as applicable, are outstanding and Petrobras has obligations under the guaranties, Petrobras will, and will
cause each of its subsidiaries to, as applicable, comply with the terms of the following covenants:

Performance Obligations under the Guaranties and Indenture

owed by it and comply with all its other obligations under the terms of the relevant guaranty and the relevant indenture in accordance
with the terms of those agreements.
