Page 10 of 32 Petrobras Press Release 08/01/2001 7:11 PM Increase in domestic petroleum production

PETROLEUM PRODUCTION INCREASED BY 8% IN JUNE

The petroleum domestic production in June achieved 1,338,491 barrels per day, 8% higher than the 1,242,324 bpd from the previous month. The reasons for this growth were both the improvement of Campos Basin operational efficiency and the operational startup of another well in Marlim Field (MRL-126), with a flow of 12 thousand barrels/day.

To increase its domestic production, Petrobras needs to produce its fields in deep and ultra- deepwaters. In 2005, the Company plans to reach a 1.9-million bopd production in Brazil and to have nearly 75% of it from deep and ultra-deepwaters.

Page 22 of 32 Appendix Strong Underlaying Fundamentals

Energy demand and offshore market fundamentals are favorable and improving Company Overview

! Oil demand growing 2 – 3% per year; crude oil prices Rig/Market Profiles have improved by 250% since beginning of 1999

Business Strategy ! Offshore production expected to increase 6% per year

Future Plans ! Deep water drilling is fastest growing area of rig demand within offshore sector Financials ! Deep water activity maintained even at low oil prices Questions

Page 24 of 32 Deepwater defined

– Begins in water depths of about 3,000 feet extending to maximum water depths of approximately 10,000 feet; current drilling record is in excess of 9,000 feet in offshore Brazil Company Overview – Relatively new market with few fields at water depths >3,000 feet Rig/Market Profiles developed before 1994

Business Strategy – Deepwater market is the strategic target for the oil majors: • Deep water fields are only remaining sources of “elephant” finds. Future Plans • Technological innovation has made it economically feasible to produce hydrocarbons in deep waters e.g. Elf’s Girassol discovery has estimated all-in costs of $6.00 per barrel Financials • Fields are outside of OPEC

Questions – Major deep water drilling markets include West Africa, Brazil, U.S., Gulf of Mexico, East Coast of Canada and the North Sea
