8. Factors Driving Gas Price Increases Lower 48 storage balances down –~300 Bcf y/y –~ 1.7 Bcf/d of additional injections to reach last year levels Gas demand remains strong despite economic conditions Gas price low in comparison to fuel oil –Gulf Coast Spot 1% - $14.64/mmbtu Lower Canadian Imports –Down ~ 0.5 Bcf/d y/y Lower LNG imports –Down ~ 2 Bcf/d y/y –Asian & European demand strong & not yet showing seasonal drop Lower 48 production offsetting lower Canadian & LNG imports –Up ~ 2 bcf/d y/y If storage is to fill to last year levels: –Must outbid Europe for LNG – recent drop in NBP price improving prospect –Or; gas price must move above resid.

9. LNG is only gas source for Japan and Korea –Will bid up price to meet demand North America is currently the market of last resort Asian & European prices are higher than US prices Source Data Paneurasian * Includes lower priced legacy contracts *

10. Forecast for LNG imports continues to drop as domestic supply grows Asia will absorb more LNG World LNG supply growth also slowing –Project cost and risk have been increasing Source Data Wood Mackenzie

11. US LNG imports will be a function of Europe and Asia demand –Same seasonal influences as North America but less storage Swings in LNG availability will lead to greater pricing volatility LNG imports will be seasonal, and vary significantly from year to year Source Data Paneurasian

15. The cost of domestic production will set the long run price of North American Gas. Source: Cambridge Energy Research Associates. 2007 Average cost estimate ~ $US 6.90 / MCF @ a 10% IRR Cost moderated in 2007 by 10 -25% but remain high

22. All this is keeping everyone very busy Our experience in 2007: –Added ~800 mcf/d of processing capacity @ 5 Plants (200 Cryogenic & 600 HDP Control) –Over 200+ Mcf/d treating capacity –400 new well connects –37,000 HP of net compression added –450+ miles of pipe Similar experiences for other midstream companies

23. Finding people to do the work Enbridge added 55 G & P staff in ‘07 Challenges: –Aging workforce –High demand –Work not always in ideal locations Response: –Work with trade schools –Apprenticeship programs

24. Other challenges for which we are working on solutions Significant inflationary pressures –Labour, equipment and materials all rising Delivery times longer –Eg. (compression delivery times up 25% in last 2 years) Right of way more expensive and more difficult to obtain

25. The fish are jump’n and the cotton is high Incredibly strong price environment Demand for gas remains solid Numerous new gas plays to exploit Challenges for Midstream are big but the opportunity greater
