If the election and all payments provided by this subsection are not made for the periods of such leave without pay occurring after November 7, 1976, the participant may not receive any credit for such periods of leave without pay occurring after such date.

A participant may make a special contribution for any period or periods of approved leave without pay while serving before November 7, 1976, as a full-time officer or employee of an organization composed primarily of Government employees.
