----------

(1)      Net income (loss) plus interest expense (net of amounts capitalized),
         income taxes, depreciation, depletion and amortization (including the
         writedown in carrying value of oil and gas properties, if any), asset
         retirement obligation accretion and cumulative effect of change in
         accounting principle (for the interim period ended March 31, 2003,
         only) should not be considered as an alternative to income (loss) from
         operations or net income (loss), as determined in accordance with
         generally accepted accounting principles (GAAP) in the United States,
         as a measure of our operating performance or to net cash provided by
         operating, investing and financing activities, as determined in
         accordance with GAAP, as a measure of our ability to meet cash needs.
         Net income (loss) plus interest expense (net of amounts capitalized),
         income taxes, depreciation, depletion and amortization (including the
         writedown in carrying value of oil and gas properties, if any), asset
         retirement obligation accretion and cumulative effect of change in
         accounting principle (for the interim period ended March 31, 2003,
         only) is a non-GAAP liquidity measure commonly used in our industry and
         we believe that it is useful adjunct to net income under GAAP and is a
         financial indicator of our ability to internally fund our exploration
         and development activities and to service debt. Amounts presented may
         not be comparable to similar measures disclosed by other companies.


(2)      Gross interest is defined as the total amount of interest incurred on
         our obligations, prior to any amounts capitalized.

(3)      Total indebtedness is defined as total long-term debt and notes.
