Refining, Transport, and Supply – Thousands Barrels/day

Feedstock processed in domestic refineries during the 1H-2006 increased 7% when compared to the 1H-2005, due to the improvements in operational reliability and the reduced number of scheduled maintenance stoppages in 2006.

In the 2Q-2006, processed feedstock by the domestic refineries was virtually flat, increasing 1% in relation to the 1Q-2006.

Feedstock processed (primary processing) by international refineries in the 1H-2006, increased by 1.4% versus the same period of the prior year, due to a lower number of scheduled maintenance stoppages in the refineries in the Argentine and Bolivian units in 2006.

In the 2Q-2006, feedstock processed by the international refineries increased 3.2%, when compared to 1Q-2006, mainly because of the lower number of scheduled maintenance stoppages, in relation to the prior quarter, in the San Lorenzo refinery in Argentina.

Refining, Transport and Supply – Th. Barrels/Day

The throughput (primary processing) at the refineries in Brazil from January through September 2005 increased 1% in relation to the same period of the previous year.

In relation to 2Q-2005, the throughput in 3Q-2005 increased 12% due to the programmed stops for corrective maintenance in 2Q-2005 at RLAM, REDUC, REGAP, and REPLAN.

Throughput of our refineries abroad from January through September 2005, increased 2.9% in relation to the same period of 2004 due to the higher production of oil products in Bolivia, especially diesel to meet higher demand in the local market as well as the export of special gasoline and reconstituted oil.

In 3Q-2005, feedstock processed by our international refineries increased 3.3% in relation to 2Q-2005, due

to the realization of the test for feedstock load in the refineries in Bolivia.

Processed throughput (primary processing) in the refineries in the country fell 2% in 1H-2005, compared to 1H-2004, due to the programmed stop at REPLAN and RECAP, at the distillation units, and at the cracking and propane units, respectively.
