<FN>
(1) Common share equivalents  result from stock options,  stock rights and stock
warrants  being  treated  as if they  had been  exercised  and are  computed  by
application  of the treasury  stock  method.  No common share  equivalents  were
assumed to be  outstanding  for the  three-months  period  ended  March 31, 1996
because accounting  standards require that the computation of earnings per share
shall not give effect to common stock  equivalents for any period in which their
inclusion would have the effect  decreasing the loss per share amount  otherwise
computed.
