Explanation of Responses:

1. These awards vest at the end of a three-year performance period that begins on January 1, 2018 and ends on the last NYSE trading day of December 2020 (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 company of the BPG, 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 be forfeited.
