         Agreement for a further term of two (2) years from the expiration of
         the said term and shall not less than three months before the
         expiration of the said term give to the Landlord notice in writing of
         such desire then the Landlord will let the said premises to the Tenant
         for a further term of two (2) years from the day immediately following
         the expiry of the said term at the New Rent and subject to this and
         save and except for this provision for renewal on the same terms and

         tenant without a premium but with vacant possession and subject to the
         provisions of this Agreement (other than the amount of the said rent
         and the provisions of this Clause) for a term of two (2) years
         commencing on the New Term Date with there being disregarded any
         goodwill attached to the Premises by reason of the carrying on there of
         business by the Tenant and the fact that the Tenant has been in
         occupation of the said premises.

                                       13

          referred by the Landlord or the Tenant to the determination of a
          referee acting as an expert.

                becomes apparent that he will be unable or unwilling to complete
                his duties the Landlord and the Tenant may agree upon or either
                of them may apply to the President for a substitute in his place
                which procedure may be repeated as many times as necessary.

          (iii) If the President is unable or unwilling to make an appointment
                at the time of application the appointment may be made by the
                Vice-President or next senior officer of the Institution then
                able and willing to make it or if no such officer is available
                by such officer of such professional body as the Landlord
                designates.

          (iv)  The referee shall afford the Landlord and the Tenant the
                opportunity to make representations subject to such
 

                                       14

 
                reasonable time and other limits as he may prescribe and he

                appointment shall be borne as the referee may direct.


     (e)  Shortfall
          ---------

          If the New Rent has not been agreed or determined by the New Term Date
          the Tenant shall continue to pay the said rent in accordance with this
          Agreement and following the New Rent being agreed or determined:-

          (i)   if there shall be any shortfall between the said rent paid as
                aforesaid and the New Rent for the period from the New Term
                Date and the date on which the New Rent is agreed or determined
                then the Tenant shall pay to the Landlord the amount of such
                shortfall; or
