4.—(1) Except where a name has been erased in accordance with the provisions of these regulations the Registrar shall retain in the appropriate roll of dental auxiliaries the name of any enrolled person in respect of whom he has received before the 31st December in every year a signed application for retention of the name until the 31st December in the next following year, accompanied by the appropriate fee.
(2) Not later than the 1st December in every year, the Registrar shall send to every person whose name is entered in a roll of dental auxiliaries a form of application for retention of a name in that roll, together with a notice of the fee payable and a warning that failure to pay will result in erasure, but failure to receive a form or notice shall not of itself constitute a ground for retention or restoration of a name.
(3) Where the Registrar on the 31st December in any year shall not have received from any person whose name is entered in a roll of dental auxiliaries a fee for the retention of that person's name in that roll for the ensuing year, the Registrar shall erase that name from the roll.
(4) The provisions of the foregoing paragraph shall not apply, except by leave of the chairman of the Committee, to any person who is the subject of a submission by the Registrar to the chairman of the Committee in accordance with the provisions of regulation 9(1).
