MOR-3 Revised 07/01/98

(1) ARO represents GAAP present value estimate of future cash flows. ARO is subject to certain potential bonding requirements, some of which have not been determined as of the date of this filing.

(2) Other long-term obligations include term NPI and ORRI interests which are accounted for as long-term obligations under GAAP because they are granted on proved properties where production is reasonably assured. Amounts associated with these other long-term obligations are not payable until production occurs.

(3) Our August 17 through August 31, 2012 income was estimated using an allocation of 15/31 days for certain line items. Our balance sheet line items represent the August 17 balances when possible; otherwise amounts presented represent July 31 balances. Because of this, an equity translation adjustment is required.
