Ref.: Official Letter No. 347/2016-CVM/SEP/GEA-1

“Mr. Director,

We refer to the news item published on August 7, 2016, in the newspaper O Estado de São Paulo, editorship Coluna do Estadão, under the title “Legal dispute in BR involves billionaire amount”, which contained the following statements:

‘A legal dispute may lead BR Distribuidora to bear RS 1 billion in order to pay the contractual fine to WTorre. The company joined the Arbitrary Council because the subsidiary of Petrobras required, without providing for termination, the nullity of the agreement for the construction of an operating unit in Rondonópolis (MT). The contractual fine is of R$600 million, but with interests it may reach the billion figure.’

This statement must take place through the Empresa.NET system, category: Notice to the Market, type: Clarifications of CVM/BOVESPA Requests, subject: News Item published in the Press, and should include a transcription of this Official Letter.”

Clarification

Petrobras Distribuidora, after an internal investigation, identified irregularities in the procedure of bidding waiver for the construction of its base of operations in Rondonópolis, Mato Grosso.

Given that, the Company filed a lawsuit against WTorre Engenharia e Construção S.A. and Taranto Fundo de Investimentos, in order to be declared the nullity of the procedure, and, consequently, of the agreement.

The lawsuit has a preliminary hearing scheduled for early September.

Petrobras has not been notified of any arbitration procedure initiated by WTorre.
