In 1945, Owen, owner of both Blackacre and Whiteacre, executed and delivered two separate deeds by which he conveyed the two tracts of land as follows: Blackacre was conveyed "To Alpha and his heirs as long as it is used exclusively for residential purposes, but if it is ever used for other than residential purposes, to the American Red Cross." Whiteacre was conveyed "To Beta and her heirs as long as it is used exclusively for residential purposes, but if it is used for other than residential purposes prior to 1965, then to the Salvation Army." In 1950, Owen died leaving a valid will by which he devised all his real estate to his brother, Bill. The will had no residuary clause.
