(f) Acquisition option of the remaining 50% of Pasadena refinery
In a preliminary decision handed down on October 24, 2008, in the arbitration process between Petrobras America Inc. and others (PAI) and Astra Oil Trading NV and others (ASTRA), which is in progress in accordance with the arbitration rules of the International Centre for Dispute Resolution, the exercise of the put option exercised by ASTRA with respect to PAI of the remaining 50% of the shares of ASTRA in Pasadena Refinery Systems Inc. ("PRSI"), a company which holds interests in Refinaria de Pasadena, and in its related trading company, both with operational offices in Texas, was considered valid. The decision also determined as valid the exercise of the sale option, by its affiliated companies, of PRSI Trading Company LP, a company set up for trading, selling and distributing crude oil and products refined by the refinery.
The operating, management and financial responsibilities were transferred to PAI, based on this preliminary decision. However, the final price to be paid for these remaining shares will be defined in the final decision to be handed down in the arbitration, since the parties disagree with respect to the value to be attributed to the shares.
No business combination has been recorded as there was no transfer of shares, exchanges of consideration and transfer of effective control.
