* Calculation of fully diluted income per share is submitted in accordance 
with Securities Exchange Act of 1934 Release No. 9083, although it is contrary 
to paragraph 40 of APB Opinion No. 15 because it produces an antidilutive 
result, or is not required by footnote 2 to paragraph 14 of APB Opinion No. 15 
because it results in dilution of less than 3%.
