Procedure to elect members of the Company's Board of Directors:

A.

Separate election

Firstly, If the requirements below are met, the Company will conduct a separate voting for the sitting member of the Board of Directors and their respective alternate.

Under the Corporations Law, the separate election will only occur if there is a request: (i) from

Shareholders holding common shares representing at least fifteen percent (15%) of the Company's voting shares, pursuant to article 141, paragraph 4, item I, of the Corporations Law, which scenario is not possible, considering the number of outstanding common shares issued by the Company (thus disregarding the shares bound to the Company's Shareholders' Agreement); or (ii) by shareholders holding preferred shares that represent, at least, ten percent (10%) of the total capital stock of the Company, pursuant to article 141, paragraph 4, item II, of the Corporations Law. If the quorums set forth in items (i) and (ii) are not achieved, the separate voting for the election of one (1) full member and respective alternate may be required by holders of common shares and preferred shares jointly representing, at least, ten percent (10%) of the total capital of the Company, pursuant to article 141, paragraph 5, of the Corporations Law.

The Shareholders (including the final beneficiaries of the American Depositary Receipts representing preferred shares) may only take part in the separate voting process for shares (or ADRs) held uninterruptedly for at least three (3) months immediately prior to the date when the Meeting is held. The proof of uninterrupted ownership of the shares (or ADRs) shall be sent directly to the Company, through [e-mail], by April 29, 2024.

The Company clarifies that, on March 18, 2024, it received from the shareholder GERAÇÃO L. PAR FUNDO DE INVESTIMENTO EM AÇÕES, represented by its attorneys-in-fact, a request for the inclusion in the remote voting ballot of effective and alternate candidates for the eventual separate election of a member and his/her respective alternate to the Board of Directors by the minority shareholders holding preferred shares, under the terms of article 141, paragraph 4, II of the Brazilian Corporate Law.

The information received by the Company regarding the professional experience of the candidates nominated by said shareholder is available in Annex V of this Proposal, in accordance with article 7,item II and article 8, item II of CVM Resolution 81 (items 7.3 to 7.6 of the Reference Form) and Annex K of CVM Resolution 80.

B.

Majority election

If the separate election is not required or is required without meeting the requirements imposed in article 141, paragraphs 4, 5 and 6 of the Corporations Law, the Company will conduct the majority election of the members of its Board of Directors, pursuant to article 129 of the Corporations Law. The slate voting system will be adopted, and the votes will be cast on a list of candidates previously determined, so that, in the end, all members appointed by Novonor and by Petrobras, which own the majority of the voting shares, will be elected.

If separate voting has occurred, one (1) of the eleven (11) vacant positions of the Board of Directors will be held by the director elected by separate election, with ten (10) vacant positions left to be occupied by the members appointed to form the ticket, subject to the provisions of the Shareholders' Agreement filed at the Company's headquarters.

The number of shares held by the Shareholders with voting rights that choose to vote separately, if applicable, will be excluded from the calculation of the number of voting shares for the purposes of the majority election.

C.

Multiple Vote

As an alternative form of voting to the majority election, which should also occur after the separate election, if applicable, the Corporations Law contemplated the possibility of adopting a multiple vote.

It should be clarified, however, that the adoption of such a form of voting is not a possible scenario for the Company, considering that the outstanding voting shares issued by the Company represent less than five percent (5%) of the voting capital stock of the Company (article 141 of the Corporations Law and CVM Ruling 70, of March 22, 2022).

4. To resolve on the election of the Chairman and Vice Chairman of the Company's Board of Directors
