The permit is for a new wellbore segment of existing well PBU 15-15-B, Permit No 202-258, API No. 50-029-2069102-00. Production should continue to be reported as a function of the original API number stated above. 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 C mission to witness any required test, contact the Commission's petroleur~.d in ec or at (907) 659-3607 (pager). ~/ DATED this -day of November, 2007 cc: Department of Fish 8v Game, Habitat Section w/o encl.

Pipe rams, blind rams and the CT pack off will be pressure tested to 250 psi and to 3500 psi. The annular preventer will be tested to 250 psi and 2500 psi. Directional • See attached directional plan. Max. planned hole angle is 90 deg. • Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. • Distance to nearest property -19,300 ft. • Distance to nearest well within pool - DS07-16A @ 1300ft. 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 DS15 is 15-20C 40 ppm 7/1/2006. • Lost circulation risk is moderate. • Additional 2 days planned because of reduced ROP. Reservoir Pressure The max res. press. is estimated to be 3300 psi at 8800'ss (7.2 ppg EMW). Max. surface pressure with gas (0.10 psi/ft) to surface is 2420 psi. The sidetrack, 15-15BL1, is scheduled to be drilled by Nordic 1 around November 18t1i, 2007. The plan calls for a slimhole lateral with a slotted liner. ~~.~ ~~ Mel Rixse CTD Drilling Engineer 564-5620 cc.
