(1) Computed utilizing the treasury stock method.
 
(2) Fully diluted earnings per share is not materially different from primary
    earnings per share for fiscal years ended March 31, 1995 and 1996. For the
    fiscal year ended March 31, 1997, for which the assumed exercise of
    outstanding stock options would be antidilutive, loss per share is
    calculated using the weighted average number of common shares outstanding.
