Refining and Sales in the Domestic Market

• 4 pp reduction in throughput due to: • Oil supply limitation;• More scheduled stoppages compared to 2Q06;

• 1 pp decrease in domestic crude participation in processed feedstock due to operational problems in Golfinho (less light oil) and increase spread between fuel oil and domestic heavy oil (more profitable to export).

• Increase in sales volume due to seasonality in agricultural diesel consumption, industrial fuel oil and substitution of imported naphtha.
