23. Canadian Natural Gas Demand by 2010 Total Canadian demand in 1999 was 8.0 Bcfd NEB forecasts consumption in 2010 at 4.3 Tcf or 11.8 Bcfd Annual GDP growth of 3% through 2005, decelerating to 2% thereafter 40% of growth occurs in eastern provinces (Ontario, Quebec and Maritimes) Oil Sands production now estimated by NEB to require 1 Bcfd of natural gas by 2010.6 Bcfd included in NEB June ’99 forecast Sources:Statistics Canada website NEB, Canadian Energy, Supply & Demand to 2025; June 1999 NEB, Canada’s Oil Sands; October 2000

39. Why are we Interested? Strategic Focus on the North Development of New Gas Supply Increase clean BTU supplies to N. America Allow market growth Improve utilization of existing pipeline grid Opportunities for New Investment Significant N. American Pipeline Project A Core Competency – “It’s What We Do For A Living!”

40. How Can We Add Value? U.S. Political/Regulatory Expertise FERC Environmental Agencies Governmental Players Successful Market Players Trading/Marketing/Risk Management Consumers - Power Plants (~13,000 MW/~2.2 Bcfd) Enron currently owns 6000 MW in US Market Access Involved in all major U.S. markets Excellent relationships with consumers Owner of significant import capacity

41. How Can We Add Value? EPC Expertise Physical Operating Capability Recognized “Best in Class” Existing Infrastructure Economies of Scale Widely Respected “Industry Innovators” Source of Equity Management Commitment

42. Conclusions Demand Will Be There IF Confidence in Supply Maintained Pricing Levels in 2007 – 2010 Appear to Support Alaskan Gas El Paso & Enron Can Supply Considerable Pipeline & Market Expertise
