If a landlord terminates the lease by at least fourteen days notice pursuant to clause (ii) of the preceding sentence, the tenant shall be entitled to cure on or before the day the answer is due in any action by the landlord to recover possession of the premises, by paying or tendering to the landlord or to his attorney all rent then due, with interest and costs of such action.
