29. BUILDING A WORLD OF DIFFERENCE ® 29 June 2007 Mid-Continent production also expected to grow on the strength of non-conventional shale gas plays

30. BUILDING A WORLD OF DIFFERENCE ® 30 June 2007 Mid-Continent production is projected to increase due to Fayetteville Shale prospects Fayetteville Shale is a Mississippian- age shale accumulation located in Arkoma Basin across several counties of Arkansas. Southwest Energy, the dominant player in the play, has drilled and completed 172 wells as of Dec. 31, 2006, of which 92 are horizontal wells. Assuming average well ultimate recovery of 1.4 Bcf and 80-acre spacing, Southwest Energy estimated an ultimate recovery of over 11Tcf Fayetteville shale production forecast is based on Lippman Consulting projections and an assumed growth rate

31. BUILDING A WORLD OF DIFFERENCE ® 31 June 2007 Woodford Shale, East OK also provides Mid-Continent production with upside potential Woodford shale is the geological equivalent of Barnett Shale and Fayetteville Shale in East Oklahoma on the west part of the Arkoma basin. Major players in Woodford shale include Newfield Exploration and Devon Energy. Newfield plans to drill 233 to 322 new wells by 2009. Newfield Exploration estimates the ultimate recoverable reserves ranges from 2 – 5 Tcf Woodford Shale production forecast is based on Lippman Consulting projections

47. BUILDING A WORLD OF DIFFERENCE ® 47 June 2007 Summary & Conclusions Natural gas market expected to continue being tight in the near term – largely weather dependent High price volatility will continue in the near term due to combined tight supply-demand balance, and the risk of supply or demand (weather) shocks New gas supplies from shale and Rockies production are key to meeting long-term demand New production areas have triggered new pipeline capacity projects to provide access to markets LNG still has much uncertainty around it, as does an Alaskan pipeline project Storage is more critical than ever to managing demand cycles. Storage value has been increased by supply reliability considerations coupled with: Resurgence in liquidity Expanding number of energy market participants – traders/marketers LNG Imports off-peak
