    Sec. 11-159. Annuity after withdrawal while disabled for employees who first became participants prior to January 1, 2011.
    (a) This Section applies to employees who first became participants prior to January 1, 2011.
    (b) An employee whose disability continues after the employee has received ordinary disability benefits for the maximum period of time prescribed by this Article and who withdraws before age 60 while still so disabled is entitled to receive an annuity in such amount as can be provided from the total sum accumulated to the employee's credit from employee contributions and employer contributions, to be computed as of the employee's age on the date of withdrawal. If the minimum annuity under Section 11-134 applies and is greater than the annuity under this subsection (b), then the Section 11-134 annuity shall apply. Any annuity under this subsection (b) shall be subject to automatic annual increases under Section 11-134.1.
    (c) The annuity to which the employee's spouse shall be entitled upon the employee's death shall be fixed on the date of the employee's withdrawal. It shall be provided on a reversionary annuity basis from the total sum accumulated to the employee's credit for widow's annuity on the date of such withdrawal. If the minimum annuity under Section 11-145.1 applies and is greater than the annuity under this subsection (c), then the Section 11-145.1 annuity shall apply. Any widow's annuity shall not be subject to any automatic annual increases.
    (d) Upon the death of any such employee while on annuity, if the employee's service was at least 4 years after the date of the employee's original entry, and at least 2 years after the date of the employee's latest re-entry, the employee's unmarried children under age 18 shall be entitled to an annuity as specified in this Article for children of an employee who retires after age 55, subject to prescribed limitations on total payments to a family of an employee.
