- ------------------

(1)   The Company does not receive a tax benefit for $5 million of transaction
      costs written off to interest expense when the Company retired its
      preferred interests of subsidiaries in September 2003. Given the
      non-deductibility of the charge, $9 million of pre-tax income is required
      to cover the $5 million write-off. Accordingly, interest expense has been
      grossed up by $4 million.

(2)   Represents the portion of rental expense assumed to be attributable to
      interest factors of related rental obligations determined at interest
      rates appropriate for the period during which the rental obligations were
      incurred. Approximately 32 to 34 percent applies for all periods
      presented.

(3)   The Company does not receive a tax benefit for a portion of its preferred
      interests of consolidated subsidiaries. As a result, these amounts
      represent the pre-tax earnings that would be required to cover preferred
      interests requirements of consolidated subsidiaries.

(4)   The Company does not receive a tax benefit for its preferred stock
      dividends. As a result, this amount represents the pre-tax earnings that
      would be required to cover its preferred stock dividends.
