OGX OVERVIEW

4. OGX OVERVIEW
Highly successful and experienced management team, combining unique intellectual capital and
superior execution skills
Overall exploratory success rate exceeding 85% with high productivity reservoirs amongst the best in
Brazil
World class E&P portfolio, mostly in shallow waters and onshore (low cost and off-the-shelf technology)
OGX is among the largest pure E&P companies globally
Proven execution capability (from concept to oil in an unprecedented timing) with fully established
operations comprising more than 6,000 people
Solid cash position allows OGX to conduct the largest and most successful private sector exploratory
campaign in Brazil and to support production development (more than 100 wells spud since the beginning
of its exploratory campaign in Sep. 2009)
Brazil‟s historical under-exploration underpins massive growth opportunities for OGX
