Petrobras Subsidiary Announces Debt Tender Offers

Petroleo Brasileiro S.A. ( Petrobras) reported that its wholly owned subsidiary, Petrobras International Finance Corp. (PIFCo), has commenced a cash tender offer for any and all of the five series of notes listed in the table below.

This transaction is intended to allow Petrobras and PIFCo to reduce overall indebtedness and take advantage of their strong cash flow generation. In addition, because Petrobras and PIFCo received an investment-grade rating in October 2005 by Moody's Investor Service, they expect to have an ability to raise funds on more favorable terms than were available at the time PIFCo issued the original notes.

Information pertaining to the repurchase:

PIFCo has commenced the cash tender offers for any and all of the aggregate principal amount outstanding of the five series of notes described in the table below, subject to the conditions and limitations described in the offer to purchase dated July 18, 2006, including the condition that PIFCo shall not have received tenders of notes in all offers having an aggregate principal amount in excess of U.S.$1 billion (the "Maximum Tender Condition"), excluding certain notes currently held by PIFCo or its affiliates that it intends to tender, or cause to be tendered, in the offers. In the event that the Maximum Tender Condition is not met, PIFCo may terminate one or more offers in order to cause this condition to be satisfied, beginning with the offer for the notes bearing the longest maturity and continuing in decreasing order of maturity.

The purchase price for each $1,000 principal amount of notes validly tendered and not validly withdrawn pursuant to an offer shall be the price (calculated as described in the offer to purchase) equal to the present value on the settlement date of such principal amount and the present value of the interest payments due on such principal amount from the last interest payment date through the applicable maturity date indicated in the chart above, determined on the basis of a yield to the applicable maturity date equal to the sum of (x) the bid-side yield of the applicable reference treasury security indicated in the chart above and calculated as described below, plus (y) the applicable fixed spread indicated in the chart above, minus accrued and unpaid interest from the last interest payment date to, but excluding, the settlement date, payable on the settlement date. In addition, registered holders of notes who validly tender and do not validly withdraw their notes in an offer will also receive accrued and unpaid interest from the last interest payment date with respect to the relevant series to, but excluding, the settlement date, payment on the settlement date.
