Explanation of Responses:
(1)	Each performance stock unit represents a contingent right to receive between 0% and 200% of one share of Issuer common stock. The reported number of securities represents the target number of shares that may be earned. The actual number of shares that may be earned will be calculated based on the Issuer's return on invested capital over a three-year performance period.
(2)	Each performance stock unit represents a contingent right to receive between 0% and 150% of one share of Issuer common stock. The reported number of securities represents the target number of shares that may be earned. The actual number of shares that may be earned will be calculated by comparing the Issuer's relative total shareholder return to the total shareholder return for each company comprising the Issuer's peer group over a three-year performance period.
(3)	This stock option award vests in four equal installments of 25% each, beginning on the first anniversary of the grant date.
(4)	Each restricted stock unit represents a contingent right to receive one share of Issuer common stock. Vesting of the restricted stock units is contingent on satisfaction of a performance hurdle tied to the Issuer's 2018 financial performance.
