ANNUAL SHAREHOLDERS' MEETING

ADJUSTMENT IN THE VOTING PROCEDURE

RIO DE JANEIRO, April 19, 2013 /CNW/ - HRT Participações em Petróleo S.A. (the "Company" or "HRT") (BM&FBOVESPA: HRTP3, TSX-V: HRP) informs its shareholders, in connection with the announcement released on April 16, 2013, that the voting procedure for the election of Board Members has been adjusted and will occur through the adoption of the cumulative voting procedure (voto múltiplo).

According to the cumulative voting procedure and considering that (i) there will be 11 vacant positions in the Company's Board of Directors; and (ii) each 2 Global Depositary Shares corresponds to 1 Common Share, each 1 Common Share or each 2 Global Depositary Shares shall grant to its owner 11 votes to be allocated among the candidates.

Therefore, due to the adoption of the cumulative voting procedure, the information and guidelines provided by the Company to the shareholders, namely those who do not participate in the meetings in person and cast their votes through voting instructions, are, at this time, outdated and inaccurate.

In this regard, the Company kindly suggests to the shareholders who have already casted their vote through HRT's electronic voting platform to revoke their previous votes and vote again on the revised matters already listed on that voting platform www.assembleiasonline.com.br, which can be accessed through HRT's investor relations homepage www.hrt.com.br/ir. Electronic proxies will be accepted by the platform up to 11:59 p.m. (Rio de Janeiro time) on April 26, 2013.

For the holders of HRT's Global Depositary Shares, Deutsche Bank Trust Company Americas, the Depositary of the Global Depositary Shares will send a new voting instruction form duly adjusted. The Depositary has fixed 12:00 p.m. (New York Time) on April 26, 2013, or no later than forty-eight (48) hours (excluding Saturdays, Sundays and holidays) before the time of any adjourned Annual Ordinary Meeting, as the time by which written voting instructions must be received from holders of Global Depositary Shares in order for such written voting instructions to be carried out by the Depositary pursuant to the terms of the deposit agreement.

In view of the above, as informed in the announcement released on April 16, 2013, the Shareholders can allocate their votes to elect the new members of the Board of Directors among the following candidates:

I.     The Management of the Company proposes Messrs. Marcio Rocha Mello, Milton Romeu Franke, Wagner Elias Peres, John Anderson Willott, Elias Ndevanjema Shikongo, Carlos Thadeu de Freitas Gomes, William Lawrence Fisher, Joseph P. Ash, Peter L. O'Brien, Thomas W. Ebbern, and Charles Laganá Putz, as candidates for the Board of Directors of the Company, as previously presented in the Management Proposal.
