    Sec. 11-163. Restoration of rights. An employee who has withdrawn as a refund the amounts credited for annuity purposes, and who (i) re-enters service of the employer and serves for periods comprising at least 90 days after the date of the last refund paid to him or (ii) has completed at least 2 years of service under a participating system (as defined in the Retirement Systems Reciprocal Act) other than this Fund after the date of the last refund, shall have his annuity rights restored by making application to the board in writing for the privilege of re-instating such rights and by compliance with the following provisions:
        (a) After that 90 day or 2 year period, whichever
    
applies, he shall repay in full to the Fund, while in service, all refunds received, together with interest at the effective rate from the application dates of such refund or refunds to the date of repayment.
        (b) If payment is not made in a single sum, repayment
    
may be made in installments by deductions from salary or otherwise, in such manner and amounts as the board, by rule, may prescribe, with interest at the effective rate accruing on the unpaid balance. The employee shall be credited with interest at the effective rate from the date of each installment until full repayment is made.
        (c) If the employee withdraws from service or dies in
    
service before full repayment is made, service credit shall be restored in accordance with Section 11-221.2(b).
        (d) If the employee withdraws from service or dies in
    
service during the required 90 day or 2 year period, any repayments made shall be refunded, without interest thereon and in accordance with the refund provisions of this Article.
        (e) If the employee repays the refund while
    
participating in a participating system (as defined in the Retirement Systems Reciprocal Act) other than this Fund, the service credit restored must be used for a proportional annuity calculated in accordance with the Retirement Systems Reciprocal Act. If not so used, the restored service credit shall be forfeited and the amount of the repayment shall be refunded, without interest.
