NOTE 1 — DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION

Atlas America Public #10 Ltd. (the "Partnership") is a Pennsylvania limited partnership and formed on July 5, 2001 with Atlas Resources, LLC serving as its Managing General Partner and operator ("Atlas Resources" or "MGP"). Atlas Resources is an indirect subsidiary of Atlas Energy, L.P., formerly Atlas Pipeline Holdings, L.P. ("Atlas Energy") (NYSE: ATLS). On February 17, 2011, Atlas Energy, a then-majority owned subsidiary of Atlas Energy, Inc. and parent of the general partner of Atlas Pipeline Partners, L.P. ("APL") (NYSE: APL), completed an acquisition of assets from Atlas Energy, Inc., which included its investment partnership business; its oil and gas exploration, development and production activities conducted in Tennessee, Indiana, and Colorado, certain shallow wells and leases in New York and Ohio, and certain well interests in Pennsylvania and Michigan; and its ownership and management of investments in Lightfoot Capital Partners, L.P. and related entities (the "Transferred Business").

Atlas Energy recently announced that it intends to create a newly formed exploration and production master limited partnership named Atlas Resource Partners, L.P. ("Atlas Resource Partners"), which will hold substantially all of ATLS' current natural gas and oil development and production assets and the partnership management business.

Atlas Resources' focus is on the development and/or production of natural gas and oil in the Appalachian, Michigan, Indiana, and/or Colorado basin regions of the United States of America. Atlas Resources is also a leading sponsor of and manages tax-advantaged direct investment partnerships, in which it co-invests to finance the exploitation and development of its acreage. Atlas Energy Resource Services, Inc. provides Atlas Resources with the personnel necessary to manage its assets and raise capital.
