 the decision
or by the Foundation. Any compensation for the alleged damages will only be determined by court decisions in subsequent actions.

This class action involves complex issues and the
outcome is subject to substantial uncertainties, which depend on factors such as: the scope of the arbitration clause of the Petrobras
Bylaws, the jurisdiction of the Dutch court, the scope of the agreement that ended the Class Action in the United States, the Foundation's
legitimacy to represent the interests of investors, the several laws applicable to the case, the information obtained from the production
phase of evidence, the expert analyses, the timetable to be defined by the Hague Court of Appeal and the judicial decisions on key issues
of the process, possible appeals, including before the Dutch Supreme Court, as well as the fact that the Foundation seeks only a declaratory
decision in this class action.

The Company, based on the assessments of its advisors,
considers that there are not enough indicative elements to qualify the universe of potential beneficiaries of a possible final decision
unfavorable to Petrobras' interests, nor to quantify the supposedly compensable damages.

Thus, it is currently not possible to predict whether
the Company will be liable for the effective payment of damages in any future individual claims, as this analysis will depend on the outcome
of these complex procedures. In addition, it is not possible to know which investors will be able to bring subsequent individual actions
related to this matter against Petrobras.

Furthermore, the claims formulated are broad, cover
a multi-year period and involve a wide variety of activities and, in the current scenario, the impacts of such claims are highly uncertain.
The uncertainties inherent in all of these issues affect the duration of final resolution of this action. As a result, Petrobras is unable
to estimate an eventual loss resulting from this action. However, Petrobras continues to reject the Foundation's allegations, in relation
to which it was considered a victim by all Brazilian authorities, including the STF.

Petrobras and its subsidiaries reject the allegations
made by the Foundation and will continue to defend themselves vigorously.
