(a)	$17 million and $10 million of the total $296 million and $300 million obligations are recorded in other current liabilities as of September 30, 2012 and December 31, 2011, respectively. See Note 6 for further discussion of the transaction.


(b)	$15 million of the total $182 million obligation is recorded in other current liabilities. See Note 6 for further discussion of the transaction.

(c)

In 2009, we financed 113 real estate surface assets in the Barnett Shale area for approximately $145 million and entered into a 40-year master lease agreement under which we agreed to lease the sites for approximately $15 million to $27 million annually. This lease transaction was recorded as a financing lease and the cash received was recorded with an offsetting long-term liability on the consolidated balance sheet. Chesapeake exercised its option to repurchase two of the assets in 2010 and one of the assets in 2011.

(d)

In 2009, we financed our regional Barnett Shale headquarters building in Fort Worth, Texas for net proceeds of approximately $54 million with a five-year term loan which has a floating rate of prime plus 275 basis points. At our option, we may prepay the term loan in full without penalty. The payment obligation is guaranteed by Chesapeake. As of September 30, 2012, our Barnett Shale headquarters building was classified as property and equipment held for sale on our condensed consolidated balance sheet.
