(a) that payment of any sum be made by specified instalments or be postponed to a specified date;

(b) that any security given be applied in or towards payment of the sum forfeited; or

(c) that the defendant or the surety, as the case may be, do all such things and execute all such documents as may be necessary, or as may be specified in the order, for the purpose of vesting any security in the Crown or enabling the Crown to realize the same or to resort thereto to recover the sum forfeited,

and the court or an appropriate judicial officer may at any time vary or revoke an order made under paragraph (a), (b), or (c).
