  1.  The  court  may  at  any time terminate either a period of probation,
other than a period of lifetime probation, for conviction to a crime  or  a
period of conditional discharge for an offense.
  2.  The  court  may  terminate  a period of probation for a person who is
subject to lifetime probation and who has been on unrevoked  probation  for
at least five consecutive years.
  3.  (a)  The court shall grant a request for termination of a sentence of
probation under this  section  when,  having  regard  to  the  conduct  and
condition of the probationer, the court is of the opinion that:
  (i)  the  probationer  is no longer in need of such guidance, training or
other assistance which would otherwise be  administered  through  probation
supervision;

conditions of the sentence of probation; and
  (iii)  the termination of the sentence of probation is not adverse to the

of  restitution  or  reparation,  has  made  a  good faith effort to comply
therewith.

of the sentence of conditional discharge; and
