Clarification about 4Q11 Results

Rio de Janeiro, February 16^th, 2012 – Petróleo Brasileiro S.A. – Petrobras clarifies about the news issued by the Brazilian press about the webcast for investor and analysts concerning the 2011 fourth quarter results (4Q11).

Regarding the 2012 output, the Company clarifies that the production target for the year was not disclosed yet. The information disclosed refers to the “average contribution”, in the 2012 curve, of the platforms that started producing in 2010/11 and those that are scheduled to start producing in 2012. The estimated average output of these platforms (P-57, Lula Pilot, P-56, Tiro-Sidon and Baleia Azul Pilot) in 2012 is 336,000 barrels per day (bpd), which represents an increase of 211,000 as compared with their output in 2011.

The average contribution of these units is not compared with the information disclosed during the presentation of the 2011 third quarter results (3Q11), when it was presented the total capacity of the units scheduled to start up in 2012.

Long-term oil price forecast (after 2015) was revised down from US$ 80/barrel to US$ 75/barrel, as disclosed in the webcast. The revision is made from time to time and may impact the assets value as a result of the change in the cash flow generation.

The Company states that its price policy is designed to make gasoline and diesel prices consistent with long-term trends in international prices, without transferring volatility to the domestic market.

Concerning the divestment policy, the 2011-2015 Business Plan includes the divestment amount of US$ 13.6 billion as a source of financing for capex. The Company is currently assessing different assets to be considered in this program, including opportunities of Exploration & Production in Brazil and overseas and opportunities for overseas refining.

Concerning the financial statements of 2011, released to the market on February 9^th, 2012, data adjustments needed to be made to explanatory note no. 25, relating the Expenses by Nature and Statement of Added Value, in view that part of the expenses allocated in the services item should have been included in the item acquired raw materials/products. After the correction, the Company resubmitted the financial statements on February 14^th, 2012.

These changes did not cause any change neither in the total amounts presented in the explanatory note nº 25 not in the income statement, statement of financial position, cash flow statements and other explanatory notes.

Lastly, the Company’s states that the first COMPERJ refining stage is slated to go into production in September 2014. The new date stems from the fact that more time was needed to contract utilities. The first refining stage at Refinaria do Nordeste (RNEST) is slated to go into production in June 2013 and the second stage is slated for January 2014. These changes were due to above-average rainfall and shutdowns (strikes) by contractors.
