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. The permit is for a new wellbore segment of existing well PBU 12 -05A, Permit No. 207- 053, API 50- 029 - 2039101 -00. Production should continue to be reported as a function of the original API number stated above. 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). 4 Sincerely, Dan .

For the planned drilling of this well, an 8 -1/2" intermediate hole will then be drilled from a KOP in the 9 -5/8" casing at -7000' MD to the top of the Sag River formation -8700' MD where a 7 ", 26.0# intermediate casing string will run and cemented. A 6 -W horizontal production hole will then be drilled to a final well TD at -11,890' MD where a 4 - ", 12.6 #, L -80 solid liner will be run and cemented to TD (there is the possibility of running a combination solid /slotted liner on this well). The planned completion for this well will include a 4 - ", 12.6 #, 13 chrome tubing string with 3 gas lift mandrels and a single S -3 production packer. This well is currently scheduled for Nabors 9ES beginning -07/15/09.

PPPOT -IC to 3500 psi, PPPOT -T to 5000 psi. Cycle all LDS and replace /repair as required. - DONE 3. Drift tubing to 8050' in preparation for jet cut. Not Completed - Tubing collapsed at 47'. 4. Jet cut tubing at 8041' MD (mid -first full joint of tubing above the HBBP packer at 8082' MD (see tubing tally)). NOTE: With collapsed tubing at 47', an jet cut at -40' is currently planned. 5. Circulate the well to clean seawater through the tubing cut. Cannot be done. 6. Freeze protect T & IA to -2100 MD with diesel. 7. Set BPV in tubing hanger and test to 2000 psi from below. 8. Remove wellhouse and flow -lines and level pad as required. Proposed Drilling Riq Operations: 1. MI /RU. 2. CMIT- Tx1AxOA to 2000 psi. 3. Pull BPV w /tested lubricator and circulate out diesel freeze protection and displace the well to seawater. 4. Set and re -test TWC to 2,000 psi from below and 3500 psi from above for 10 minutes. 5. Nipple down tree. Nipple up and test BOPE to 3500psi. Pull TWC w /tested lubricator. 6. RIH w /internal tubing cutter on PAC DP and cut the 4 -1/2" tubing above the collapse at -40'. 7. RU & pull 4 -1/2" tubing from the cut depth at -40' MD. 8. Test lower set of rams if required. 9. RIH w /Baker mill /dressing assembly to "polish" the 4 -1/2" tubing stub and swallow the collapsed tubing at 47' in preparation for an external tubing at -130' MD ( -90' of tubing swallow). (Note: To eliminate the possibility of cutting into the the external casing strings (the 9 -5/8" & 13 -3/8" casing strings) here should be NO external milling capabilities built into this polish mill assembly.) 10. RIH w /Baker external tubing cutter and cut the tubing at -130' MD and TOH with cutter (will bring fish out of hole with this BHA). 11. PU 4 -1/2" tubing as required and a Baker over - shot/grapple and RIH and swallow the top of the tubing at -130' MD. 12. RU E -line and make tubing cut (jet cut) at 8041' MD. 13. Circulate the well to clean seawater. 14. Pull the 4 -1/2" x 3 -1/2" completion from the tubing cut at 8041' MD. 15. PU drillpipe and make bit and scraper run to the top of the tubing stub. 16.

Freeze protect the well to 2,200' TVD with diesel. 40. Install BPV and secure the well. 41. Rig down and move off. Post -Ria Operations: (S -Riser Modification will be Required) 1. MI / RU slick line. 2. Pull the ball and rod / RHC plug from landing nipple below the production packer. 3. Install gas lift valves. 4. Install well house and instrumentation. G -13B Sidetrack Page 8 • • Drilling Hazards and Contingencies POST THIS NOTICE IN THE DOGHOUSE 1. Well Control A. With the KOP for the 8 -1/2" hole in the Colville "below" all Cretaceous injection activity, pore pressures for the intermediate hole should be "normal" (8.5 ppg) to less than normal as the interval is TD'ed into the Sag River formation (the Sag in this fault block is expected to be under - pressured at 7.4 ppg EMW). II. Lost Circulation /Breathing A. For the 8 -1/2" intermediate hole, the lost circulation /breathing potential should be minimized due to the relatively deep KOP in the Colville and given the fact the well has been design to minimize the hole angle into the top of the Sag (16 deg) to keep the mud weight relatively low (10.0 ppg). However, as there "may' be no cement behind the 9- 5/8" casing at the KOP and given the potential for a "weak" zone within the Colville below the KOP, lost circulation/breathing problems must be considered a possibility. B. As for the production interval of the well, lost circulation in the Sag River and Ivishak formations is usually fault related, however, the directional plan for this well has been optimized to eliminate the drilling of any "mapped" faults. Please refer to the MI mud program for details as they relate to dealing with lost circulation problems while drilling this interval of the well. III. Kick Tolerance /Integrity Testing Test Point Test Depth Test type EMW (lb/gal) 9 -%" window 20 -ft minimum from the 9 -%" window FIT 9.9 ppg min f /KT 3 ppg max f /ECD Mgt 7" shoe 20 -ft minimum from the 7" shoe FIT 8.9 ppg min f /KT 10.7 ppg max f /ECD Mgt IV. Stuck Pipe A. For the 8 -1/2" intermediate interval of the well, insufficient/poor hole cleaning support resulting in stuck pipe will be of primary concern. B. For the 6 -1/8" production interval of the well, both differential sticking and sticking as associated with insufficient/poor hole cleaning should be of primary concern. VI. Hydrogen Sulfide With H2S levels above the 100 ppm threshold, G -Pad is not considered an H2S pad (see below). However, as is standard practice, follow all RP recommendations as required for working in an H2S environment. Well Name H2S Level Date of Reading #1 Closest SHL Well H2S Level G-32A No data #2 Closest SHL Well 112S Level G-12B No data #1 Closest BHL Well H2S Level E-37A 14 ppm 3/8/2009 #2 Closest BHL Well H2S Level E-21B 10 ppm 11/28/2005 Max. Recorded H2S on Pad/Facility G-10C 40 ppm Other Relevant 112S Data G -Pad is not an H2S pad. (H2S alarms from rigs, etc.) VII. Faults There will be a Kingak fault crossing in the lower 6 -1/8" section of this well at -11,650' MD (Fault #3) that should be watched closely for the possibility of lost circulation. See SOR Section II on lost circulation for more details. VIII. Anti - Collision Issues There are 2 active producers (E -21 & G -31 A) and 3 non - producing wells (G -13, G -13A and G-31APB1) which do not pass Major Risk. The intersect point of these wells is "in zone ", therefore, a Tolerable Collision Risk Worksheet will be run on each well to determine if a Minor Risking of the well is appropriate and producing wells will be shut -in if required.
