(1)  Apache guaranteed and is contingently liable for certain debt. Fixed
     charges, relating to the debt for which Apache was contingently liable,
     have not been included in the fixed charges for any of the periods shown
     above.

(2)  Represents the portion of rental expense assumed to be attributable to
     interest factors of related rental obligations determined at interest rates
     appropriate for the period during which the rental obligations were
     incurred. Approximately 32 percent to 34 percent applies for all periods
     presented.

(3)  The Company does not receive a tax benefit for its preferred stock dividend
     requirements of consolidated subsidiaries. As a result, this amount
     represents the pre-tax earnings that would be required to cover preferred
     stock dividend requirements of consolidated subsidiaries of $4 million.

(4)  The Company does not receive a tax benefit for its preferred stock
     dividends. As a result, this amount represents the pre-tax earnings that
     would be required to cover preferred stock dividends of $5 million.

(5)  Earnings were inadequate to cover fixed charges and combined fixed charges
     and preferred stock dividends by $237 million and $240 million,
     respectively, due to the $243 million write-down of the carrying value of
     United States oil and gas properties.
