1.             ORGANIZATION AND NATURE OF OPERATIONS

Crimson Exploration Inc., together with its subsidiaries, (“Crimson”, “we”, “our”, “us”) is an independent energy company engaged in the exploitation, exploration, development and acquisition of crude oil and natural gas properties.  We have historically focused our operations in the onshore U.S. Gulf Coast, Texas and Colorado regions, which are generally characterized by high rates of return in known, prolific producing trends.  We have expanded our strategic focus to include longer reserve life resource plays in East Texas and South Texas that we believe provide significant long-term growth potential from multiple formations.  Our operating revenues are derived from crude oil, natural gas and natural gas liquids sales that are proceeds from the sale of crude oil, natural gas and natural gas liquids production and net realizations on associated commodity derivative instruments.
