In this sense, the start of the Early Production System (EPS) production was adjusted to consider the occurrence only at the end of 2017.

In accordance to OGX Reorganization Plan, the sale of the assets is one of the resolutions to restructure the company. The successive delays on the FPSO Petrojal I arrival and, consequently, the occurrence of the EPS first oil, significantly impacts the company's cash flow forecast, for this reason OGX is intensifying its efforts in search of potential buyers of part of its stake on BS-4 Block.

The Companies will keep the shareholders and the market informed of the developments on this matter.
