Explanation of Responses:
(1)	This award vests at the end of a three-year performance period that began on January 1, 2020 and ends on December 31, 2022(the "Performance Period"). This award survives termination of employment due to death, disability, termination by the Company without cause or retirement by the employee upon having reached 64 years of age. In all cases, the shares will vest at the end of the Performance Period as follows: 50% of the award will vest if the Company is in the top 50th percentile of Return on Invested Capital (ROIC) among the Bloomberg Peer Group (BPG), 100% of the award will vest if the Company is in the top 75th percentile of ROIC of the BPG and 150% of the award will vest if the Company is the top performing ROIC company of the BPG.
(2)	These awards will be interpolated on a straight-line basis from the 50th percentile to the 100th percentile. The amount that vests over the 100% of the award up to the maximum 150% of the award, if any, is subject to a reduction of one-half of the final percentage above 100% if absolute Total Shareholder Return for the 2020 Performance Period is negative, all as shown by data published by Bloomberg upon the close of the NYSE market on the last trading day of the Performance Period. If the minimum performance criteria is not met, then no shares shall vest and the award shall be forfeited.
