                      Computation of net income per share

In the 1995 second quarter,  the  Corporation  changed its reporting of earnings
per share  ("EPS")  from  reporting  simple EPS,  (which is based  solely on the
average  number of common shares  outstanding),  to reporting  primary and fully
diluted  EPS  (which  are  based on the  average  number of  common  and  common
equivalent shares outstanding).

Previously,  the Corporation  reported simple EPS, since the differences between
simple EPS and primary EPS or simple EPS and fully diluted EPS were not material
(less than 3%).  Primary and fully  diluted EPS are now being  reported  for all
periods presented.

Net income for  primary and fully  diluted  earnings  per share are  computed by
subtracting from the applicable earnings the dividend  requirements on preferred
stock to arrive at earnings  applicable to common stock and dividing this amount
by  the  weighted  average  number  of  common  and  common   equivalent  shares
outstanding during the period.
