(1)   Pursuant to footnote 2 to paragraph 14 of APB Opinion No. 15, the
      Company is not required to include common stock equivalents resulting
      from stock options when the effect is less 3%.  The Company has chosen to
      reflect the effect of such options within the computation of its earnings
      per share.

(2)   This calculation is submitted in accordance with Regulation S-K Item 601
      (b)(11) although not required to be shown in the Consolidated Statements
      of Income pursuant to footnote 2 to paragraph 14 of APB Opinion No. 15
      because it results in dilution of less than 3%.
