- ----------
(A)  For the purpose of determining the ratio of earnings to fixed charges,
     earnings include pre-tax income plus fixed charges (excluding capitalized
     interest). Fixed charges consist of interest on all indebtedness (including
     capitalized interest) plus that portion of operating lease rentals
     representative of the interest factor (deemed to be one-third of operating
     lease rentals). The Company's historical statements do not reflect the $300
     million of indebtedness incurred in connection with the Distribution and,
     accordingly, the historical ratios of earnings to fixed charges do not
     reflect any interest for this indebtedness.
