(1) the consent, release, or ratification of the beneficiary was induced by improper conduct of the trustee; or
(2) at the time of the consent, release, or ratification, the beneficiary did not know of the beneficiary's rights or of the material facts relating to the trustee's conduct and the trustee did know of the material facts relating to the trustee's conduct.
