The interest shall be deposited in the reserve fund and service credit granted at the time of retirement shall not exceed the lesser of ten years or fifty percent of the member's total service as a teacher in West Virginia. Any purchase of out-of-state service, as provided in this article, shall not be used to establish eligibility for a retirement allowance and the retirement board shall grant credit for the purchased service as additional service only: Provided, however, That a purchase of out-of-state service is prohibited if the service is used to obtain a retirement benefit from another retirement system: Provided further, That salaries paid to members for service prior to entrance into the retirement system shall not be used to compute the average final salary of the member under the retirement system.
