A powerholder's substantial compliance with a formal requirement of appointment imposed by the donor, including a requirement that the instrument exercising the power of appointment make reference or specific reference to the power, is sufficient if:

1. 1. The powerholder knows of and intends to exercise the power; and
2. 2. The powerholder's manner of attempted exercise of the power does not impair a material purpose of the donor in imposing the requirement.
