As a result of the Company's net loss in 1998, Anadarko's earnings did not cover
fixed charges by $90 million and did not cover combined fixed charges and
preferred stock dividends by $101 million.

These ratios were computed by dividing earnings by either fixed charges or
combined fixed charges and preferred stock dividends. For this purpose, earnings
include income before income taxes and fixed charges. Fixed charges include
interest and amortization of debt expenses and the estimated interest component
of rentals. Preferred stock dividends are adjusted to reflect the amount of
pretax earnings required for payment.
