Any employee who first becomes a contributor before the effective date of this amendatory Act of the 99th General Assembly, who has rendered service to any "governmental unit" as such term is defined in the "Retirement Systems Reciprocal Act" under Article 20 of the Illinois Pension Code, who did not contribute to the retirement system of such "governmental unit", including the retirement system created by this Article 9 of the Illinois Pension Code, for such service because of ineligibility for participation and has no equity or rights in such retirement system because of such service shall be given credit for such service in this fund, provided:
        (a) the employee shall pay to this fund, while in the
service of such county, or while in the service of a governmental unit whose retirement system has adopted the "Retirement Systems Reciprocal Act", such amounts, including interest at the effective rate, as he would have paid to this fund, on the basis of his salary in effect during the service rendered to such other "governmental unit" at the rates prescribed in this Article 9 for the periods of such service to the end that such service shall be considered as service rendered to such county, with all the rights and conditions attaching to such service and payments; and
        (b) this Section shall not be applicable to any
period of such service for which the employee retains credit in any other public annuity and benefit fund established by Act of the Legislature of this State and in operation for employees of such other "governmental unit" from which such employee was transferred.
