                      Group Operating Vice Presidents

TERMS:        Participants will receive a bonus of 1 percent of base pay for
              each 1 percent increase in excess of a 10 percent increase, up to
              a 15 percent increase, in current fiscal year customer sales over
              previous fiscal year customer sales for their respective
              operations. Participants will receive a bonus of 2 percent of base

              Also, sales growth above 15 percent will result in additional
              payments under the Plan only if the operating group is exceeding
              corporate goals with respect to its return on sales and its
              assets/sales ratio.
