Except as provided by 26 U.S.C. 6323, if a person becomes a purchaser, holder of a security interest, mechanic's lienor, or judgment lien creditor after a notice of lien is filed in accordance with § 70.148 of this part, the interest acquired by such person is subject to the lien imposed by 26 U.S.C. 6321.
