Oil product sales in the domestic market grew 7% in comparison with 2Q09, due to:

o 6,5% increase in diesel sales as a result of recovering economic activity and improved grain harvest;

o 13% growth in gasoline sales. Growth was led by increase in the usage of gasoline in flex fuel vehiclescaused by ethanol shortage and temporary reduction of anhydrous ethanol in the gasoline blend;

o 15% increase in jet fuel sales (economic recovery leading to increased aviation).
