As a result of the 3 for 2 stock split to be  distributed on March 28, 1997, per
share amounts for 1996 have been restated to reflect the weighted average number
of shares of common stock outstanding,  increased by shares issued for the stock
split.  The per share  amounts in 1996 are  calculated as though the stock split
occurred on the first day of the year.

                                               March 29, 1997   March 30, 1996
