No provision of an instrument creating a trust, including the provisions of any further trust created, and no other disposition of property made pursuant to exercise of a power of appointment granted in or created through authority under such instrument is invalid under the rule against perpetuities, or any similar statute or common law, during the one hundred fifty years following the effective date of the instrument.
