NOTE:     For the purpose of calculating this ratio, (i) earnings have been
          calculated by adjusting net earnings for taxes on earnings; interest
          expense; capitalized interest cost, net of amortization; minority
          interest; and the portion of rentals representative of the interest
          factor, (ii) the Company considers one-third of rental expense to be
          the amount representing return on capital, and (iii) fixed charges
          comprise total interest expense, including capitalized interest and
          such portion of rentals.
