- ----------

(a) Before cumulative effect of changes in accounting principles of $59,032 in
    1992.

(b) Beginning in 1995, interest expense includes the effects of debt
    incurred in October 1995 in connection with the Company's asset
    restructuring and initial public offering and debt incurred in October
    and November 1996 to refinance such initial debt (see Note 2 to the
    Consolidated Financial Statements).

(c) Due to lower earnings, primarily caused by lower hydrocarbon prices and
    higher fixed charges resulting from higher interest expense, earnings
    are deficient by $10,214 to cover fixed charges.
