(4)	Each performance right represents a contingent right to receive one share of the issuer's common stock at vesting. The performance rights vest at a rate between 0% and 200% and are based on two factors during a three-year performance cycle beginning on January 1, 2018 and ending on December 31, 2020 which are: 1) the issuer's relative total share holder return ("TSR") in comparison to the TSR averages of a predetermined peer group over the performance cycle; and 2) the issuer's return on invested capital measured against the issuer's performance relative to its weighted average cost of capital and relative to a predetermined peer group over the performance cycle. The performance rights may be settled, at the issuer's discretion, in cash or shares of common stock.
