We are a midstream natural gas company providing comprehensive services to natural gas producers, including natural gas gathering, compression, dehydration, treating, marketing, transportation, processing and fractionation services. Our assets are located in Texas, Oklahoma, Wyoming and Louisiana.

Since our founding in 1992 with a single 23-mile pipeline, we have grown through a combination of acquisitions and organic expansion. Today we provide midstream services for producers of approximately 1,500,000 MMBtu per day of natural gas. Significant milestones in our growth include:

• The 2001 purchase of the Houston Central Processing Plant, one of the largest gas processing and treating plants in Texas
  
  
• The 2005 acquisition of Tulsa-based ScissorTail Energy, LLC, establishing a significant presence in central and eastern Oklahoma
  
  
• The 2007 acquisition of Denver-based Cantera Natural Gas, LLC, which established our presence in the Rocky Mountains region
  
  
• Beginning in 2010, major organic expansions in south Texas to meet the needs of producers in the Eagle Ford Shale resource play.
