Paragraph 21

A person any of whose shares have been forfeited shall cease to be a member in respect of them and shall surrender to the company for cancellation the certificate for the shares forfeited but shall remain liable to the company for all moneys which at the date of forfeiture were presently payable by him to the company in respect of those shares with interest at the rate at which interest was payable on those moneys before the forfeiture or, if no interest was so payable, at the appropriate rate (as defined in the Act) from the date of forfeiture until payment but the directors may waive payment wholly or in part or enforce payment without any allowance for the value of the shares at the time of forfeiture or for any consideration received on their disposal.
