disposition shall be made unless and until (1) Commerce has
advised such owners that it has received an opinion from its
legal counsel satisfactory to it that no post-effective
amendment to Commerce's registration statement, if any, filed
with the Securities and Exchange Commission (Commission) under
the Securities Act of 1933 (Act) and no other registration
under said Act is required to such disposition, or (2) such
