  police  and  fire retirement system, membership in the retirement system
  shall cease upon the occurrence of any one of the following conditions:
1. When seven years have elapsed since a member has  performed  active
  service  provided, however, that no part of such seven year period shall
  run during such time as a member, with at least  five  years  of  member
  service  credit,  shall  serve  as an officer or employee of the federal
  government or the United Nations or other international organizations of
  which the United States of America is a member.
2. When a member shall die.

  retirement  system  within  five  years  from  the  date he discontinued
  service with the state or a participating employer, such person shall be
  entitled to every retirement right, benefit and  privilege  which  would
  have  been  available  to him had he reentered membership on the date of
  such discontinuance from service.
