(Cheniere LNG Marketing) has entered into a 10-year Gas Purchase and Sale Agreement with PPM. Upon completion of certain facilities, the agreement gives Cheniere LNG Marketing the ability to sell to PPM up to 600,000 MMBtus of natural gas per day at a Henry Hub related market index price, and calls for Cheniere to allocate to PPM a portion of the liquefied natural gas (LNG) that it procures under certain long-term LNG supply agreements. Terry Hudgens, PPM's CEO, said, "PPM Energy is delighted to have been selected by Cheniere to purchase long term LNG supply into the U.S. Gulf Coast Market. PPM considers this an important strategic relationship that links its growing gas storage supply and marketing business to Cheniere's leading LNG terminal business. LNG will become a vital part of U.S. natural gas supply over the next several years and PPM will be well positioned to offer LNG along with domestic supply and storage services to its growing gas customer base." Cheniere LNG Marketing President, Keith Meyer said, "PPM has taken a proactive step in addressing North America's natural gas supply shortfall by helping to pull long-term LNG supply into North America. PPM's network of storage capacity and its natural gas marketing platform are assets that complement Cheniere's LNG receiving network and Cheniere LNG Marketing's LNG procurement business. We view this venture as a strategic relationship that will play off the strengths of both parties to our mutual benefit." PPM Energy, Inc.
