<FN>
NOTES:      (A)   Share and per share data have been restated to reflect
                  2-for-1 stock split effected on August 31, 1992.

            (B)   Computed under the "Treasury Stock Method" using the higher
                  of quoted ending or average market price.

            (C)   Fully diluted earnings per share have not been presented in
                  the consolidated statements of income because the dilutive
                  effect is less than 3%.
