We refer to the news item published today in the newspaper Folha de São Paulo, Panel section, under the title: “Billions at Sight”, which contained the following statements:

Petrobras will close two more big sales. One of them may be of its gas pipeline network. A technician close to the negotiations say that the operations will yield about US$ 4 billion

In view of the above, we request that you clarify whether the information in question is true, and if so, why it was not disclosed through a Material Fact, as well as comment on other information deemed relevant to the issue.”
