Primary earnings per share is computed by dividing net income by the
weighted average number of common shares outstanding for each period.
The calculation excludes the effect of common equivalent shares
resulting from stock options using the treasury stock method as the
effect would not be material.

Fully diluted earnings per share is computed based on the weighted
average number of common shares and common equivalent shares outstanding
for each period.

(1) This calculation is submitted in accordance with Regulation S-K Item
601(b)(11) although not required by APB Opinion No. 15 because it
results in dilution of less than 3%.
