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.

Well G -08A was sidetracked in March 2007 as a CTD sidetrack. The well reached marginal GOR within 3 months. The well was placed on a 14 , day on / 21 day off cycle and showed good recharge until August 2009. Additional perforations were added in May 2009 and the well came on strong for two months then gas rates climbed back up to pre add -perf levels. Six months of being shut in showed no recharge. The proposed plan for G -08B is to sidetrack out of the G -08A 3- 3/16" liner with the Nordic 1 Coiled Tubing Drilling rig on or around Sept. 01, 2010. The existing perforations will be isolated by the packer whipstock set , at 11,830' and the primary cement job after drilling and running liner. The sidetrack will exit the 3- 3/16" liner and drill a 3" hole in the Ivishak Zone 2A. CTD Sidetrack Summary Pre -Rig Work: (scheduled to begin July 15, 2010). 1. S Dummy WS drift to 12,200'. 2.

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. Hole size: 3" Casing Program: fully cemented liner • 2 -3/8 ", L -80, 4.7# STL connection solid liner from 11,740' — 13,095'. • A minimum of 7.3 bbls 15.8 ppg cement will be used for liner cementing. (Assuming TD @ 13,095' and planning on 20% excess in the open hole interval) • TOC planned at 11,740'. Well Control: • BOP diagram is attached. • 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. Maximum planned hole angle is 89 °. • Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. • Distance to nearest property — 21,840' ft to the North. • Distance to nearest well within pool — 500 ft. to G -18A (west). Logging • MWD directional and Gamma Ray will be run over all of the open hole section. • Cased hole GR /CCL/MCNL logs will be run. Anti - Collision • G -17A: G -08B will pass within 1,169' of G -17A at 11,910' MD.- Hazards • One small throw fault crossings expected in the horizontal near 12,750'md, 15 -20' DTW. • The maximum recorded H2S level on G -Pad was 40 ppm on well G -10C. G -pad is not considered an H2S pad. • Lost circulation risk is considered normal for this well. Reservoir Pressure • The reservoir pressure on G -08B is expected to be 3,227 psi at 8,800' TVDSS. (7.05 ppg equivalent) • Max. expected surface pressure with gas (0.10 psi /ft) to surface is 2,347 psi.
