(2) In subsection (3), a reference to the period of reduced contributions of a contributor to whom this section applies shall be read as a reference to that part of his period of previous contributory qualifying service as occurred after the time that is the time from which, by reason of his being an existing contributor of the kind referred to in paragraph (1)(c), he commenced to make contributions to the Fund at a rate less than the rate that would otherwise have applied to him.
(3) Where an amount equal to 5.5% of the amount of aggregate pay of an existing contributor to whom this section applies in respect of his period of reduced contributions exceeds the amount of his previous contributions made in respect of that period, he shall pay an additional contribution to the Commonwealth under this section of such amount, not exceeding the amount of the excess, as CSC determines as being appropriate in the circumstances.
