1 Gomez Development Lessons Learned Successful Fast Track Deepwater Project Sanction to Production in 16 months Ability to Expand to 6 Wells Currently Working on Increasing Capacity Current Deepwater Development favors Dry Trees 1

2 Key Features Gross Proved Reserves: ~100 Bcfe Gross Probable Reserves: ~40 Bcfe ATP Working Interest: 100% Planned Wells: 3-4 2

3 Development Considerations Lack of Nearby Infrastructure Multiple Pay Horizons Short Field Life Cost/Availability of Deepwater MODU s Presence of Satellite Discoveries 3

4 MinDOC Platform Draft 430 ft Displacement: 61,300 ST Lightship: 17,900 ST Max Payload: 12,000 ST Heave 100 yr: 8 ft Pitch/Roll 100 yr: 9 deg 4

5 MinDOC Design Advantages Three Columns vs One Column Build in Shipyard or Fab Yard Distributed Waterplane Area enhances Stability Smaller Cylinders reduce VIM Excellent Motion Characteristics High Topsides Payload/Hull Weight Ratio Provides Dry Trees Can be Easily Relocated 5
