Except as otherwise provided in this rule, evidence of the following is not, in any civil or criminal proceeding, admissible against the defendant who made the plea or was a participant in the plea discussions:

However, such a statement is admissible (i) in any proceeding wherein another statement made in the course of the same plea or plea discussions has been introduced and the statement ought in fairness be considered contemporaneously with it, or (ii) in a criminal proceeding for perjury or false statement if the statement was made by the defendant under oath, on the record and in the presence of counsel.
