3. 3 NYSE: GDP COMPANY PROFILE AND STRATEGY ■ Rapidly growing onshore E&P company focused in Louisiana and Texas. Repeatable development of multiple objectives with long life reserves and near 100% success rate ■ Rapidly growing production volumes (5 yr CAGR of 34%) and reserves (5 yr CAGR of 24%) ■ Sale of non-core assets for $70 million provides additional liquidity and drives per unit operating costs lower ■ Increasing liquids volumes and cash margin expansion from Eagle Ford Shale oil development ■ Large core acreage position with 220,000 gross (185,000 net) acres in Texas and Louisiana, with approximately 7 Tcf of reserve exposure: ■ 91,000 net acres prospective in the Haynesville Shale ■ 40,000 net acres in the oil window of the Eagle Ford Shale in La Salle and Frio counties Texas ’05 – ’09 CAGR: 25% ’05 – ’09 CAGR: 36%

4. 4 NYSE: GDP EAGLE FORD SHALE – OIL WINDOW ■ Why the Eagle Ford Shale Oil Window ■ Excellent Rock Properties. Very good porosity (4-15%), matrix permeability (40-1,300 nd) and fracture complexity for a shale play. Allows for storage (source rock) and flow (over-pressured reservoir rock) ■ High presence of carbonate and low presence of clay allows for very effective fracs. Expect variability due to naturally occurring fractures, possible communication with other zones and pressure differences due to depth ■ Large accumulation of oil in place (25-55 MMBoe per 640 ac). Vertical well production indicates matrix flow and hyperbolic curve. Artificial lift a necessity once pressures drop ■ Early innings, but estimated recovery of 300-800 MBoe per well on 80-120 acre spacing based on 4,000 – 6,000 foot laterals

5. 5 NYSE: GDP ACREAGE AND WELL ECONOMICS Eagle Ford Shale Acquisition: Combination of leasehold acquisitions and joint ventures Total consideration - $1,650/ac ($575/ac in cash and $1,075/ac in future drilling carries). Average working interest of 72.5% (56% NRI). At 80-120 acre spacing yields 333 – 500 net locations Superior Economics: Driven by oil prices/cash margin expansion Eagle Ford - IRR of 45% for 6,000 foot lateral on completed well cost of $7.0 million and estimated EUR of 465 MBOE Buda – IRR of 58% for 6,000 foot lateral on completed well cost of $3.5 million and estimated EUR of 265 MBOE

8. 8 NYSE: GDP Drilling Procedure 1,000+ HP rig with top drive Drill time: EFS - 30 days spud-to-spud (approximately 22 days to TD). Targeting 6,000 foot laterals. Spud-to-sales dependent on frac availability (two dedicated frac dates per month) and infrastructure Buda – 25 days drill time, 30 days spud-to-spud and spud-to-sales due to no need for stimulation Casing program: Surface casing - 10 ¾” through Carrizo (~ 3,700’) Intermediate casing – None in quiet geological areas; 7 5/8” into top of EFS or Buda (~ 7,500’) in highly fractured areas Production casing - 5 ½”, with 2 3/8” – 2 7/8” tubing for EFS and open hole with tubing on Buda wells Mud program: EFS – water base (vertical), oil base (lateral) Buda – water base throughout

9. 9 NYSE: GDP Completion Procedure Induce complex networks of fractures with pump-down plug and perf method Frac Design: Intervals of 300-325 feet Perforations (6 clusters, 5 shots per cluster = 30 perfs per stage) Fluids (5,500 Bbls per stage - acid, slickwater, gel) Proppant – 230,000 lbs per stage (100 mesh, 20/40 white, resin coated/ceramic) Pump rate (65 bpm, 3-5 stages per day) Flowback – 50-100 BPH. Artificial lift (gas lift, pump) at some point early in life of the well

15. 15 NYSE: GDP POTENTIAL IMPACT OF EAGLE FORD SHALE TO GOODRICH PETROLEUM Liquids rich resource play allows for cash margin expansion and superior rates of return Oil play provides great flexibility in allocation of capital based on commodity price realizations and forecasts Huge resource potential for the acreage increases GDP inventory and unrisked net asset value by 10%, and by a much greater percent when factoring in the improved economics due to current premium in oil prices versus gas Continue to acquire acreage in our core areas primarily through JV structure (cash and carried interest)
