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 contradiction: (1) furnishing, promising, or offering – or accepting, promising to accept, or offering to accept – a valuable consideration in order to compromise the claim; and (2) conduct or a statement made during compromise negotiations about the claim. B. Exceptions.
