The adjusted equity award is otherwise subject to the same terms and conditions that applied to the original award immediately prior to the spin-offs, unless otherwise noted. The reporting person's equity based awards reflect the conversion adjustments. ( 9 )This option became exercisable beginning on this date. ( 10 )This option is no longer exercisable beginning on this date.
