(1) As of the date of this report, Atlas Resource Partners, L.P. ("ARP") is a wholly-owned subsidiary of Atlas Energy, L.P. ("ATLS") (NYSE: ATLS), through ATLS' ownership of all of ARP's common units and the ownership by ATLS of Atlas Resource Partners, GP, LLC ("ARP GP"), the general partner of ARP. ARP GP owns all of ARP's Class A Units and incentive distribution rights. ATLS has announced that the board of directors of the general partner of ATLS has approved the distribution of approximately 5.24 million common units representing an approximately 19.6% limited partner interest in ARP (and approximately 20% of the ARP common units) to the holders of ATLS' common units. The distribution of common units of ARP will be made after the close of trading on March 13, 2012 to ATLS unitholders of record as of the close of business on February 28, 2012, the record date for the distribution. (Continued in Footnote 2)
(2) ATLS will distribute 0.1021 of an ARP common unit for each common unit of ATLS outstanding as of the record date. Unitholders will receive cash in lieu of fractional ARP common units. Immediately following the distribution, ATLS will continue to own approximately 20.96 million ARP common units, representing an approximately 78.4% limited partner interest in ARP (and approximately 80% of the ARP common units). In addition, ATLS will continue to own 100% of the equity of ARP GP, which, in turn, will continue to own all of the ARP Class A Units, representing a 2% general partner interest in ARP, and incentive distribution rights in ARP.
