(1) actively employed by the state;
(2) receiving workers' compensation benefits for an injury sustained while employed by the state; or
(3) on authorized sick leave.
(d) A death benefit may not be paid under this section if, at the time of death, a death benefit annuity became effective.
(e) A beneficiary designation that names a former spouse as beneficiary is invalid unless the designation is made after the date of the divorce.
