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 2030 Notes or the 2036 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 2030 Notes or the 2036 Notes, as applicable, and the relevant indenture, Petrobras will be obligated
to make such payments pursuant to the relevant guaranty.

Covenants

For so long as any of the 2030 Notes or the 2036 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

Petrobras will pay all amounts
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.

Maintenance of Corporate Existence

Petrobras will maintain in
effect its corporate existence and all necessary registrations and take all actions to maintain all rights, privileges, titles to property,
franchises, concessions and the like necessary or desirable in the normal conduct of its business, activities or operations. However,
this covenant will not require Petrobras to maintain any such right, privilege, title to property or franchise if the failure to do so
does not, and will not, have a material adverse effect on Petrobras taken as a whole or have a materially adverse effect on the rights
of the holders of the Notes.

So long as a series of the Notes is outstanding, Petrobras will maintain an office or agency in the United States where notices to and demands upon Petrobrasin respect of the guaranty for such series of Notes may be served.
