Compromise Offers And Negotiations

(a) Prohibited Uses. Evidence of the following is not admissible, on behalf of any party, either to prove or disprove the validity or amount of a disputed claim or to impeach by a prior inconsistent statement or a contradiction: (1) furnishing, promising, offering, accepting, promising to accept, or offering to accept a valuable consideration in compromising or attempting to compromise the claim; and (2) conduct or a statement made during compromise negotiations. (b) Exceptions. The court may admit this evidence for another purpose, such as proving a witness's bias or prejudice, negating a contention of undue delay, or proving an effort to obstruct a criminal investigation or prosecution. The court need not exclude evidence otherwise discoverable merely because it is presented in the course of compromise negotiations.
