2. .. 2 f:/JOB/PROSPECTS/C6074 PURVIN & GERTZ, INC.  Employee–owned consultant firm, founded in 1947  Independent of any holding company,engineering firm, process licensor or any Arctic gas project developer or stakeholder  Extensive experience on frontier, Arctic and other gas projects  In a position to provide well- founded, objective views and advice Source: http://www.gov.nt.ca

3. .. 3 f:/JOB/PROSPECTS/C6074 DRIVERS FOR ALASKA GAS DEVELOPMENT  Concerns over current and future gas supply with consequent increase in price  Strong long-term gas demand outlook  Drive to monetize stranded gas assets with impressive economic potential  Strong stakeholder support WWW.GASHYDRATE.COM

4. .. 4 f:/JOB/PROSPECTS/C6074 STAKEHOLDERS BROADLY DEFINED  Alaska producers  Other “commercial” players (e.g. transportation companies, project suppliers)  Large energy users (Alaska and nationwide)  Governments (Federal, State, Local) Source: www.anwr.com

5. .. 5 f:/JOB/PROSPECTS/C6074 MARKET DRIVERS  Long term future U.S. gas demand growth about 1.5% per year (economic growth, electricity sector, competitive pricing)  Canada around 2% annually, additionally supported by intensive industrial growth in West  A large conventional resource base that can be developed but still needs new incremental sources of supply Source: www.anwr.com

6. .. 6 f:/JOB/PROSPECTS/C6074 LOWER 48 GAS DEMAND BY END USE 2002

7. .. 7 f:/JOB/PROSPECTS/C6074 SUPPLY CONSIDERATIONS  Future Demand Further Outstrips Conventional Supply  Costlier New “Conventional” Production  New Economic Supplies are Essential

8. .. 8 f:/JOB/PROSPECTS/C6074 INCREMENTAL SOURCES OF GAS MUST BE DEVELOPED Lower 48 Supply

9. .. 9 f:/JOB/PROSPECTS/C6074 Why Alaska Gas? $US/MMBtu (Constant 2003 $) at a Henry Hub Price Equivalent  LNG (varies from $4.00):  low/medium reserve uncertainty  Medium/high transportation costs  Mackenzie Delta gas (>$3.00):  medium reserve uncertainty  high transportation costs  Alaska gas (>$3.00):  low reserve uncertainty  high transportation costs  Other  Scotian Slope (deeper water) and Grand Banks (too expensive)  Offshore East Coast, CA, BC (out-of- bounds)  Mexico (constitution/high local demand)  Hydrates (too speculative)  Arctic Islands (too far)  Canadian coalbed methane (interesting potential/not enough)

10. .. 10 f:/JOB/PROSPECTS/C6074 WHAT PRICES ARE REQUIRED? Constant 2003 U.S. Dollars per MMBtu at Henry Hub

11. .. 11 f:/JOB/PROSPECTS/C6074 WHAT ARE THE RISKS?  The most sensitive quantifiable risk elements to the economics of Arctic gas development are market price and project costs  Less sensitive factors are return on equity, the cost of debt and the debt-equity ratio  Other “qualitative” risks include politics, regulatory and environmental processes (uncertainty, delays, costs), and social (expectations of benefits)

12. .. 12 f:/JOB/PROSPECTS/C6074 POTENTIAL MARKET IMPACTS  4 or more BCFD from Alaska has the potential to cause severe but temporary market dislocations  Same order of magnitude as all incremental supply growth out of Western Canada but in one big lump  Mitigating measures would likely be undertaken to encourage the development of major incremental markets  Additional pipeline capacity required within Western Canada as well as takeaway capacity toward California, Midwest, and U.S. Northeast

13. .. 13 f:/JOB/PROSPECTS/C6074 CONCLUSIONS  Strong gas demand coupled with an uncertain lower 48 supply outlook remain the fundamental drivers for Arctic gas development  Challenges will be overcome and economic projects in both Alaska and Mackenzie Delta areas will be developed within the next ten years.  Expanded opportunities for energy goods and service industries in Alaska on the horizon Source: www.anwr.com
