|
|
|
|
Each
tranche represents a portion of the PSUs covering the number of shares outlined in the table above. Each tranche vests upon (i) satisfaction
of the market capitalization milestones and (ii) continued employment as CEO of the Company from the grant date through December 31,
2030. Absent an earlier termination, the PSUs will expire on December 31, 2030. If our CEO ceases employment as CEO of the Company for
any reason including death, disability, termination for cause or without cause (as defined in the award agreement), or if he voluntary
terminates after service as CEO for at least five years, the remaining service period will be waived and he will retain any PSUs that
have vested through the date of termination.
