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 aII 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, conta.ct the Commission's petroleum field inspector at (907)~9-3607 (pager).

Fault #1 has been crossed 1 time with no losses. Fault #2 has not been crossed previously, but trends in the same direction as fault #1. No losses are expected. • The maximum recorded H2S level on K pad was 25 pp~ on well K-16AL2. K pad is not considered an H2S pad. • Lost circulation risk is low.

(3) All True Vertical Depths (TVDSS) are SubSea corrected. (4) All Formation Evaluation data is realtime data. (5) Baker Hughes INTEQ utilized CoilTrak downhole tools and the Advantaqe 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 pownhole Pressure, Vibration and Downhole Weight on Bit), a Directional and Gamma Sub, and a Hydraulic Orienting Sub with a Near Bit Inclination Sensor. (7) Data presented here is final and has been depth adjusted to a PDC (Primary Depth Control) log provided by Schlumberger GR CNL dated 14 May 2008 per poug Stoner with BP Exploration (Alaska), Inc. (8) Tied to K-04B at 9589 feet MD (8778.2 feet TVDSS). (9) The sidetrack was drilled from K-04B through a milled window in a 4 1/2 inch liner. Top of window 9611 ft.MD (8777.5 ft.TVDSS) Bottom of window 9617 ft.MD (8777.1 ft.TVDSS) (10) Baker Hughes INTEQ run 7 through 17 were used to drill K-04PB1 and K-04PB2. (11) Baker Hughes INTEQ run 18 was utilized to open hole sidetrack at 9890 feet MD (8751.1 ft TVDSS). (12) The interval from 11588 feet to 11616 feet MD (8653.5 feet to 8653.0 feet TVDSS) was not logged due to sensor to bit offset at well TD.

(5) Baker Hughes INTEQ utilized CoilTrak downhole tools and the Advantaqe 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 pownhole Pressure, Vibration and Downhole Weight on Bit), a Directional and Gamma Sub, and a Hydraulic Orienting Sub with a Near Bit Inclination Sensor. (7) Data presented here is final and has been depth adjusted to a PDC (Primary Dep th Control) log from well K-04C dated 12 May 2008 per poug Stoner with BP Exploration (Alaska), Inc. (8) Tied to K-04B at 9589 feet MD (8778.2 feet TVDSS). (9) K-04CPB1 was drilled from K-04B through a milled window in a 4 1/2 inch liner. Top of window 9611 ft.MD (8777.5 ft.TVDSS) Bottom of window 9617 ft.MD (8777.1 ft.TVDSS) (10) The sidetrack K-04CPB2 was drilled from K-04CPB1 with an open hole whipstock at 9950 ft MD (8746 ft. TVDSS). (11) The interval from 10709 feet to 10735 feet MD (8689.7 feet to 8690.0 feet TVDSS) was not logged due to sensor to bit offset at we11 TD. (12) There is no resistivity data from 9950 feet to 10735 feet MD. No resistivity tool was being run while drilling this sidetrack.
