4 Project Description Opal to Southeast Aggregates Wyoming gas through existing El Paso infrastructure with minimal new facilities Aggregates Wyoming gas through existing El Paso infrastructure with minimal new facilities First 600 MDth/d to Greensburg at favorable rate First 600 MDth/d to Greensburg at favorable rate –Does not require large commitments – can expand for 150 Mdthd –Rate is not less favorable for small shippers –Rampable with growth; avoids stranded demand charges –Project does not have to be supported entirely by Wyoming producers or State of Wyoming –Direct access uses existing El Paso pipeline infrastructure from Opal, Wind River, Wamsutter, and Powder River –Earmarked production is from Wyoming, not Colorado 1 to 2 Bcf/d expansion from mid-continent to southeast 1 to 2 Bcf/d expansion from mid-continent to southeast –42 pipe –Highest growth market in U.S. –Anchored by 500 MDth/d+ commitments from mid-continent –Predominately existing mid-continent production, which will alleviate Rockies basis Late 2007 in-service to Greensburg, mid 2008 in-service to Perryville and Pugh, Alabama Late 2007 in-service to Greensburg, mid 2008 in-service to Perryville and Pugh, Alabama Not an end-to-end Greenfield project, so timing delays minimized and environmental impacts much less Not an end-to-end Greenfield project, so timing delays minimized and environmental impacts much less Fewer regulatory and environmental issues to delay or deter project or strand shipper at intermediate delivery points Fewer regulatory and environmental issues to delay or deter project or strand shipper at intermediate delivery points

5 Projected North American Demand Mexico Western Canada Eastern Canada NW and Alaska Maritimes and Northeast U.S Total Total Bcf/d Source: El Paso

6 Project Summary Expecting to complete transportation letter agreement for commitment from mid-continent of 500 MDth/d this week Expecting to complete transportation letter agreement for commitment from mid-continent of 500 MDth/d this week –Primarily existing production –Will free up capacity from Greensburg on existing pipes –Will alleviate Rockies basis issue minimum of 1 year faster than alternatives at less cost to Rockies producer Project utilizes existing infrastructure through most of route Project utilizes existing infrastructure through most of route

7 Project Schedule Preliminary engineering complete Preliminary engineering complete NEPA pre-filing starting this week NEPA pre-filing starting this week –NEPA scope much smaller than cross country Greenfield project Open season on-going Open season on-going Rates for different segments are established Rates for different segments are established Anticipate final agreements in January Anticipate final agreements in January FERC filing in late 2006 for entire project FERC filing in late 2006 for entire project Avoids risk of phased filing approach where project could stall at intermediate delivery points Avoids risk of phased filing approach where project could stall at intermediate delivery points Start construction in spring 2007 Start construction in spring 2007 In-service to Greensburg late 2007 In-service to Greensburg late 2007 In-service to Perryville and Pugh mid 2008 In-service to Perryville and Pugh mid 2008

8 Project – One Other Consideration Alaska Pipeline has stepped up horizon for delivery to U.S. given U.S. price levels Alaska Pipeline has stepped up horizon for delivery to U.S. given U.S. price levels –3 to 3.5 Bcf/d pipeline; 35 Tcf of recoverable gas –Producers are currently negotiating agreement with Alaska –Would follow with NEPA work in preparation of filing applications to Canada and U.S. Federal regulatory agencies –Will enter through Northwest, Chicago, and Northeast –Estimated 2012 in-service timeline per recent report
