A provision of a trust relieving a trustee of liability for breach of trust is unenforceable to the extent that it:
Except for provisions intended to provide protection for carrying out a stated purpose in the trust instrument, an exculpatory provision drafted or caused to be drafted by the trustee is invalid as an abuse of a fiduciary or confidential relationship unless the trustee proves that the exculpatory provision is fair under the circumstances and that its existence and contents were adequately communicated to the settlor.
