(a)  Based on a daily average.
(b)  This calculation is submitted in accordance with Regulation S-K, item
     601(b)(11) although not required by footnote 2 to paragraph 14 of APB
     Opinion No. 15 because it results in dilution of less than 3%, and is
     contrary to paragraph 40 of APB Opinion No. 15 because it produces an
     anti-dilutive result.
