 before the Market Arbitration Chamber (Câmara de Arbitragem do Mercado - CAM), linked to the Brazilian Stock Exchange
(B3), brought by investors who purchased Petrobras’ shares traded on B3. Six of these arbitrations were initiated by national and
foreign investors. The other proceeding was brought by an association that is not a shareholder of the Company and intended to be a collective
arbitration, through representation of all non-controlling shareholders of Petrobras that acquired shares on B3 between January 22, 2010
and July 28, 2015. Investors claim alleged financial losses caused by facts related to the investigations of the so-called Lava Jato investigation.

These claims involve complex issues that are subject
to substantial uncertainties and involve factors such as the novelty of the legal theories, the timing of the Chamber of Arbitration decisions,
the information produced in discovery, besides analysis by retained experts.

The claims asserted are broad and span a multi-year
period. The uncertainties inherent in all such matters affect the amount and timing of their ultimate resolution. As a result, the Company
does not have elements that allow it to provide a reliable estimate of the potential loss in this arbitration.

Depending on the outcome of the remaining complaints,
the Company may have to pay substantial amounts, which may have a significant effect on its consolidated financial position, financial
performance and cash flows in a certain period. However, Petrobras does not recognize responsibility for the losses alleged by investors
in these arbitrations.

These arbitrations are in different stages of processing.

In relation to one of the arbitrations, proposed
by two institutional investors, on May 26, 2020, a partial award was issued which generally recognized the Company's responsibility, but
not determined the payment of amounts by Petrobras. Against these decisions, Petrobras filed a lawsuit for the annulment of the partial
arbitral award on July 20, 2020, as the Company understands that the award contains serious flaws

and improprieties. On November 11, 2020, the
5th Business Court of Rio de Janeiro annulled the partial arbitration award, recognizing the serious flaws and improprieties pointed out
by Petrobras. At the moment, the ruling is awaited after the appeals filed at the time have been judged. The appeals against this decision
are still pending judgement
