About Atlas Energy, L.P.

Atlas Energy, L.P. ("Atlas Energy" – NYSE: ATLS) is a publicly-traded master limited partnership ("MLP"). Atlas Energy owns the general partner of Atlas Pipeline Partners, L.P. ("APL" – NYSE: APL), a midstream energy service provider engaged in the gathering and processing of natural gas in the Mid-Continent region of the U.S., namely in Oklahoma and Texas. Atlas Energy is also a leading sponsor of tax-advantaged direct investment natural gas and oil partnerships, a business which we have operated for over 40 years through several Atlas entities.

Our goal is to grow our business and cash flow to the benefit of our unitholders from:

• Increased cash flow from our general partner interest in APL;
• Further development of natural gas & oil properties, namely through our syndicated drilling program business; and,
• Expansion through acquisition of producing properties

In conjunction with the Chevron-Atlas Energy, Inc. merger, which was completed on February 17, 2011, the Partnership owns the following assets and investment interests:

• Ownership of the general partner of APL, which consists of a 2.0% general partner interest as well as 100% ownership of the incentive distribution rights in APL. These incentive distribution rights entitle ATLS to receive an increasing portion of any cash distributed by APL as it reaches certain target levels in excess of $0.42 per APL common unit in any quarter. ATLS also owns over 5.75 million common units of APL, or approximately 10.8% of the outstanding APL common units;
• Management of our leading tax-advantaged direct investment natural gas and oil partnership business. We generally structure our investment partnerships so that, upon formation, we co-invest in and contribute leasehold acreage to it, enter into drilling and well operating agreements with it and become its managing general partner. Over the past 5 years, we have raised over $1.5 billion in investor funds;
• Working interest in over 8,500 gross natural gas wells located in the following regions:
  • Appalachia region –western Pennsylvania, eastern Ohio and southwestern New York;
  • New Albany Shale region in southwestern Indiana;
  • Northeastern Tennessee; and,
  • Niobrara region in northeastern Colorado;
• An 18% general partner interest in Lightfoot Capital Partners, L.P. ("Lightfoot"). Lightfoot was established in 2006 to incubate assets which would qualify to be placed in new MLPs. Lightfoot currently owns interest in a metallurgical and steam coal business, as well as a refined products terminal and storage operation; and,
• Several midstream assets, consisting primarily of natural gas treating facilities in Tennessee and Indiana.
