The transaction is expected to close by the third quarter of 2013 and is subject to certain regulatory approvals and closing conditions. The transaction will be funded by the our existing committed credit facilities. Highlights of the acquisition include the following:


•	200 miles of gathering pipeline;

•	Rose Valley II plant - A 200 mmcfd cryogenic processing plant, expected to be in operation in in the first quarter of 2016;


•	Approximately 540,000 net acre dedication in the core of the Mississippi Lime play, supported by a recently announced joint venture between Chesapeake and Sinopec International Petroleum Exploration and Production Corporation; and
