(1) with respect to property which is not or was not subject to New York death tax in the estate of the grantor of such power, but would have been so taxable except for a statute providing that the tax on the transfer of such property should be imposed in the estate of the grantee of such power in the event of its exercise; and
(2) the exercise of which has not required the inclusion of the property in the decedent's federal gross estate under section two thousand forty-one of the internal revenue code (relating to general powers of appointment).
