DMMO3; OTC: DMMOY), in accordance with article 157, paragraph 4th of Brazilian Corporate Law No. 6,406/76 and CVM Rule No. 358/02, informs the shareholders and general market that took notice yesterday of the arbitration award issued by the Arbitration Court ("Decision") in relation to the first phase of the arbitration managed by the London Court of International Arbitration - LCIA, established by Dommo Energia against Queiroz Galvão Exploração e Produção S.A. ("QGEP") and Barra Energia do Brasil Petróleo e Gás Ltda. ("Barra"), according to material fact disclosed on October 23rd, 2017.

The aforementioned Decision declares, among other issues, that the notification issued by Barra on October 17th, 2017, in order to exercise, without offer of payment, the option to demand the exclusion of the Company from the Joint Operating Agreement - JOA, the Consortium agreement and the Concession agreement, all related to the BS-4 Block - as disclosed in the material fact on October 20th, 2017 -, was valid at the time it was issued, and shall become effective since the date of its receipt by the Company, on October 11th, 2017, without prejudice to the annulment possibility of this exclusion in a subsequent step of the arbitration proceeding, with the production of evidence that support such annulment.
