(A)   The interest factor related to rentals reflects the appropriate portion of
      rental expense representative of an interest factor.

(B)   Includes $110.0 gain on Razorfish shares in the first quarter of 2000.

(C)   The  March 31,  2002  amounts  exclude  goodwill  amortization.  Effective
      January 1, 2002 in accordance  with Financial  Accounting  Standards Board
      Statement No. 142 -- "Goodwill and other  Intangibles" the company stopped
      recording goodwill amortization expense.

(D)   The March 31, 2001 amounts include goodwill  amortization.  For comparison
      purposes,   the  March  31,  2001  profit  before  tax  without   goodwill
      amortization expense would have been $193,646 and the March 31, 2001 ratio
      of earnings to fixed charges without goodwill  amortization  expense would
      have been 4.21x.
