Except as otherwise provided under section 13 of the Bank Holding Company Act, and notwithstanding any other provision of law, the prohibitions and restrictions under section 13 of Bank Holding Company Act shall apply to the activities and investments of a banking entity identified in paragraph (c) of this section, even if such activities and investments are authorized for the banking entity under other applicable provisions of law.
