** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1) This award vests at the end of a three-year performance period that began on January 1, 2019 and ends on December 31, 2021 (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 shall be forfeited.

Note: File three copies of this Form, one of which must be manually signed. If space is insufficient, see Instruction 6 for procedure.
