§47-2-307.
   
   (a) In the event a member of the System obtains a leave of absence, of
   not to exceed ninety (90) days at any one time, because of injury or
   illness or for any personal reason other than the acceptance of other
   employment, his membership in the System shall not terminate and the
   period of such leave shall be counted toward retirement for length of
   service if, during such leave of absence or at the end thereof, he
   shall pay to the Fund an amount equal to the contributions which would
   have been deducted from his salary during such period if such leave of
   absence had not been obtained, but if such contributions are not paid
   during such leave or made up within thirty (30) days after the end of
   such leave, or if such leave of absence extends for more than ninety
   (90) days at any one time, the period of such leave shall not be
   counted toward length of service for retirement nor in computing the
   amount of any pension or any retirement pay or any other benefits
   hereunder.
   
   (b) In the event a member of the System obtains a leave of absence for
   the purpose of accepting other employment, or if a member resigns and
   during such resignation accepts other employment, his membership in
   the System shall terminate as of the date of the beginning of such
   leave. Provided, that if the membership of a member of the System
   shall have been terminated either by such leave of absence or by
   termination of employment, and such former member is reemployed, the
   Board, upon application therefor made in the same manner as an
   original application for membership in the System, may reinstate such
   membership. Such reinstated member shall be allowed full credit toward
   retirement for all service credit accrued up to the time of
   termination of membership if, but only if:
   
   1. Such application for reinstatement is made within three (3) years
   from the date of such termination of such membership; and
   
   2. Such reinstated member remains a member of the System for a period
   of five (5) consecutive years after reinstatement of membership; and
   
   3. Such reinstated member reimburses the Fund, at the time application
   for reinstatement is made, with the amount of any portion of his
   membership contribution which has been refunded to him under the
   provisions of Section 2-308 of this title.
   
   The provisions of this subsection shall not apply to absences caused
   by such military service as may be considered as service for
   retirement for length of service under the provisions of subsection
   (c) of this section.
   
   (c) In determining the eligibility of a member for retirement based
   upon length of service, any service in the Armed Forces of the United
   States or any component thereof between the 16th day of September,
   1940, and the 30th day of June, 1954, and any service in the Armed
   Forces of the United States or any component thereof upon call of the
   President of the United States or of the Governor of the State of
   Oklahoma, together with such prior service, as would have been
   otherwise considered as service for retirement for length of service,
   shall be considered as service for length of service, provided that
   the member returns and files application for reinstatement as a member
   of the System within ninety (90) days after his release, or
   opportunity for release, from such Armed Forces or component thereof.
   If such member shall have been refunded any portion of his membership
   contributions as provided in Section 2-308 of this title, he shall be
   required to reimburse the Fund with the same amount at the time of his
   application for reinstatement in the System, before the reinstated
   member is given credit for accrued prior service. Provided, that in no
   event shall a member of the System who has entered such Armed Forces
   or component thereof prior to retirement be or become eligible for
   retirement for length of service unless he shall thereafter have been
   reinstated as a member of the System as provided for herein, and
   thereafter remained a member for at least one (1) year after such
   reinstatement.
   
   (d) Time spent on involuntary furlough by members pursuant to the
   rules of the Office of Personnel Management shall be credited.
   
   (e) Notwithstanding any provisions herein to the contrary,
   contributions, benefits and service credit with respect to qualified
   military service shall be provided in accordance with Section 414(u)
   of the Internal Revenue Code of 1986, as amended.
