Atlas Energy Resources LLC

Atlas Energy is a limited liability company focused on the development and production of natural gas principally in the Appalachian Basin and northern Michigan. Our indirect subsidiary, Atlas Resources, LLC, sponsors and manages natural gas drilling partnerships, in which we co-invest, to finance the exploration and development of our acreage in the Appalachian Basin. We are active principally in Pennsylvania, Michigan and Tennessee.

Atlas Energy was formed in 2006 to own and operate substantially all of the natural gas and oil assets and the investment partnership management business of Atlas America, Inc., which has been in the energy industry since 1968. Atlas America expanded its operations in 1998 when it acquired The Atlas Group, Inc. and in 1999 when it acquired Viking Resources Corporation, both involved in the development and production of natural gas and oil and the sponsorship of investment partnerships. In May, 2007, Atlas Energy announced the acquisition of DTE Gas & Oil Company (DGO), a wholly owned subsidiary of DTE Energy Company.

At Atlas Energy, we believe we have established a strong track record of growing our reserves, production and cash flows through a balanced mix of natural gas and oil exploration, development and Atlas Resources' sponsorship of investment partnerships. Our drilling operations are located in the Appalachian Basin and in northern Michigan's Antrim Shale.

Based in Pittsburgh and Traverse City, we have an in-house team of professional geologists, petroleum engineers, and skilled production and pipeline professionals who have been responsible for drilling and completing all the wells in our natural gas drilling partnerships. We operate more than 6,600 oil and gas wells in Pennsylvania, Ohio, Tennessee and New York, which are all situated within the Appalachian Basin. We also have a strong operating team for properties outside of the Appalachian Basin, most notably in northern Michigan's Antrim Shale.

Our executive management team has substantial experience in the energy industry, with our financial and operational executives averaging more than two decades of experience in natural gas and oil. In addition, our management has a successful track record of managing public energy companies, growing proved reserves and production through drilling and strategic acquisitions and integrating acquired properties. Our management team is supported by technical and operating managers with an individual average of more than 24 years of expertise in the basins in which we operate.
