(a)   The above table presents selected pro forma information on operating cash
      flows of MCV in a format consistent with that presented in the Feasibility
      Study to the Prospectus filed as part of MCV's Registration Statement on
      Form S-1 (File No. 33-3977). This format is used to compute various debt
      service coverage ratios on an annual basis by aligning annual operating
      cash flows with the semi-annual rent payments made in July and January of
      each year. For example, the cash flow presented for 2000 reflects revenues
      and expenses associated with 2000 activity, as well as the Lease rental
      payments made on July 23, 2000, and January 23, 2001. In addition to the
      revenues presented in this table, interest income on reserves totaled
      $13.4 million in 2000 and $9.3 million in 1999.

(b)   Includes use of funds available for payment of spare parts, maintenance
      and capital expenditures that had been reserved in prior years and funding
      of reserves for future spare parts, maintenance and capital expenditures.
