This permit to drill does not exempt you from obtaining additional permits or an approval required by law from other governmental agencies and does not authorize conducting drilling operations until all other required permits and approvals have been issued. In addition, the Commission reserves the right to withdraw the permit in the event it was erroneously issued. Operations must be conducted in accordance with AS 31.05 and Title 20, Chapter 25 of the Alaska Administrative Code unless the Commission specifically authorizes a variance. Failure to comply with an applicable provision of AS 31.05, Title 20, Chapter 25 of the Alaska Administrative Code, or a Commission order, or the terms and conditions of this permit may result in the revocation or suspension of the permit. When providing notice for a representative of the Commission to witness any required test, contact the Commission's petroleum field inspector at (907) 659-3607 (pager).

Mud Program: • Well kill: 8.4 ppg brine. • Milling/drilling: 8.6 ppg Flo Pro or biozan for milling, new 8.6 ppg Flo Pro for drilling. Disposal: • All drilling and completion fluids and all other Class II wastes will go to Grind & Inject. • All Class I wastes will go to Pad 3 for disposal.

Directional • See attached directional plan. Maximum planned hole angle is 91.9 deg at 11,465'. • Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. • Distance to nearest property - 23,900 ft. • Distance to nearest well within pool -1,200 ft. (18-16B) Logging • MWD directional, Gamma Ray will be run over all of the open hole section. • A cased hole MCNL/GR/CCL log will be run. Hazards The maximum recorded H2S level on DS 18 is 20 ppm on well 18-14B. • Lost circulation risk is medium. Reservoir Pressure • The reservoir pressure on 18-32A is unknown. After a significant increase in water production in April of 2006, a static bottom hole pressure survey was run and produced water samples were taken. SBHP was measured at 3,993 psi at 8800'ss (8.73 ppg EMW). This pressure was much higher than expected, and not consistent with expected Ivishak pressures in the region. Fluid analysis indicates that the produced water is consistent with water from the cretaceous. Mechanical integrity testing has confirmed a failed IA with a leak rate of 2 bpm at 1500 psi. A cretaceous leak is suspected which would account for the higher than expected pressure and water production. Due to debris in the wellbore, it is not possible to pull the isolation plug in the XN nipple to obtain an accurate indication of formation pressure in this well. • DS 18-16 is an offset well in the same fault block as the current 18-32A lateral. It is a good analog for 18-32A. DS 18-16 had a bottom hole pressure in August of 2007 of 3,317 psi at 8800' TVD (7.25 ppg eq.)

(3) All True Vertical Depths (TVD) are Subsea corrected. (4) All Formation Evaluation data is realtime data. (5) Baker Hughes INTEQ utilized CoilTrak downhole tools and the Advantage surface system to log this well. (6) Tools ran in the string included Casing Collar Locator, an Electrical Disconnect and Circulating Sub, a Drilling Performance Sub (Inner and Outer Downhole Pressure, Vibration and Downhole Weight on Bit), a Directional and Gamma Sub, and a Hydraulic Orienting Sub with a Near Bit Inclination Sensor and Ultra Slim Resistivity Sub. (7) Data presented here is final and has been depth adjusted to a PDC (Primary Depth Control) log provided by Schlumberger - GR CNL as per Roger Furley with BP (Alaska) Exploration, Inc. Resistivity data has also been clipped at 2000 ohm.m. (8) The sidetrack was drilled from 18-32 through a milled window in 4 1/2 inch liner. Top of window 9240 ft.MD (8185.7 ft.TVDSS) Bottom of window 9248 ft.MD (8191.9 ft.TVDSS) (9) Tied to 18-32 at 9192 ft.MD (8147.7 ft. TVDSS) (10) The resistivity data from 9234 feet to 9867 feet MD (8180.9 feet to 8645.4 feet TVDSS) was MAD passed up to 62 hours after drilling. The MAD pass data was substituted for drilled data per the wellsite geologist. (11) The interval from 11335 feet to 11376 feet MD (8649.7 feet to 8649.9 feet TVDSS) was not logged due to sensor to but offset.
