- ----------
*    Not meaningful
(1)  The Company had no material debt and, consequently, had no material fixed
     charges for each of the periods presented. The ratio of earnings to fixed
     charges is determined by dividing earnings by fixed charges. Fixed charges
     consist of the total of (i) interest, whether expensed or capitalized; (ii)
     amortization of debt expense and discount or premium relating to any
     indebtedness, whether expensed or capitalized; (iii) such portion of rental
     expense as can be demonstrated to be representative of the interest factor
     in the particular case; and (iv) preferred stock dividend requirements of
     majority-owned subsidiaries and fifty-percent-owned persons, excluding in
     all cases items which would be or are eliminated in consolidation. Earnings
     consist of pretax income from continuing operations plus the amount of
     fixed charges, adjusted to exclude (i) the amount of any interest
     capitalized during the period and (ii) the actual amount of any preferred
     stock dividend requirements of majority-owned subsidiaries and
     fifty-percent-owned persons which were included in such fixed charges
     amount but not deducted in the determination of pretax income. The ratio of
     earnings to fixed charges is not meaningful for periods in which there were
     no material fixed charges.
