Dear Ms. Nicholson:

By letter dated September 30, 2008, the Securities and Exchange Commission (the “Commission”) provided certain comments related to the annual reports on Form 20-F filed on May 19, 2008, by Petróleo Brasileiro S.A.—PETROBRAS (“Petrobras”) and Petrobras International Finance Company (“PifCo,” and together with Petrobras, the “Companies”).

The Commission asked the Companies to respond to such comments or tell the Commission when they will respond within ten business days, which deadline would have elapsed today. On October 14, 2008, counsel for the Companies contacted you by telephone to request a one-week extension of that deadline. You granted the Companies’ request. Consequently, the Companies undertake to submit a response to the Commission’s comments on or before Tuesday, October 21, 2008.

Petrobras and PifCo appreciate the staff’s accommodation in this matter.

.

Ms. Laura Nicholson
