Aspen Pipeline Fund II

Aspen Pipeline II (“Aspen II”) was initially formed in January 2008 to co-invest with Aspen Pipeline (ESP IV) in the Odessa Fuels project, a natural gas pipeline in West Texas constructed to gather and deliver high nitrogen content natural gas to customers capable of directly burning the natural gas without nitrogen removal. Aspen II sold its interest in the Odessa Fuels project to DCP Midstream (NYSE: DCP) in January 2012.
