If the trial court intends to reject the plea agreement, the trial court shall, on the record, inform the defendant personally that (1) the trial court is not bound by any plea agreement; (2) the trial court intends to reject the plea agreement presently before it; (3) the disposition of the present case may be less favorable to the defendant than that contemplated by the plea agreement; and (4) that the defendant may then withdraw his or her guilty plea as a matter of right. If the plea is not then withdrawn, sentence may be pronounced.
