(C) A member participating in the STRS defined benefit plan who has at least one and one-half years of contributing service with the state teachers retirement system, is a former member of a uniform retirement system, and has received a refund of contributions to that uniform system shall, in computing years of total service, be given full credit for service credit earned under Chapter 742. or 5505. of the Revised Code or for military service credit if, for each year of service, the state teachers retirement system receives the sum of the following:

(1) An amount, which shall be paid by the member, equal to the amount refunded by the uniform system to the member for that year for accumulated contributions and payments for military service credit, with interest at a rate established by the state teachers retirement board on that amount from the date of the refund to the date of the payment;

(2) Interest, which shall be transferred by the uniform system, on the amount refunded to the member that is attributable to the year of service from the last day of the year for which the service credit was earned or in which payment was made for military service credit to the date the refund was made;
