Under the terms of the 2016 Directors Stock Unit Plan, as amended (the "2016 Plan"), vested units under the 2016 Plan are not acquirable by the Director until, at the election of the Director: (i) the vesting of the units at the one-year anniversary of the grant or (ii) the time of the Director's termination of service.
