                  time be unpaid for 14 days after becoming payable (whether

                  thereafter to re-enter the Demised Premises or any part
                  thereof in the name of the whole and thereupon the term
                  created hereby shall absolutely determine but without
                  prejudice to the right of action of the Landlord in respect of
                  any antecedent breach of the Tenant's obligations herein
                  contained.

                  within two days following that on which it was posted.

         4.7.     Insofar as terms and provisions of this Lease are inconsistent
                  with the terms and provisions of the Registered Land Law,
                  (1995 Revision) the said Registered Land Law, (1995 Revision)
