    5.3      ESSENTIAL TERMS

             The Lessee's covenants:

             5.3.1        to pay the Rent and the Outgoings; and

             5.3.2        not to assign, sublet, transfer or part with
                          possession of the Premises or any part thereof or of
                          the benefit of this Lease without obtaining the prior
                          written consent of the Lessor,

             are essential terms of this Lease and any breach of any of those
             covenants shall be regarded by the Lessor and the Lessee as a
             fundamental breach and repudiation by the Lessee of this Lease. If
             the Lessor determines this Lease following such a breach and
             repudiation then (without prejudicing or limiting any other right
             or remedy of the Lessor arising from the breach or otherwise under
             this Lease) the Lessor shall be entitled to recover from the Lessee
             and the Lessee covenants to pay to the Lessor as and by way of
             liquidated damages for the breach and repudiation the aggregate of
             the Rent and Outgoings which would have been payable by the Lessee
             for the unexpired residue of the Term remaining after the
             determination after making allowance for Rent and Outgoings which
             the Lessor by taking reasonable steps to re-let the Premises
             obtains or could reasonably be expected to obtain by reletting the
             Premises for the unexpired residue of the Term on reasonable terms
             as to Rent and otherwise PROVIDED THAT:

             5.3.3        any reletting shall not be required to be on like
                          terms as are herein expressed and implied;

             5.3.4        the acceptance by the Lessor of arrears or any late
                          payment of the Rent or Outgoings shall not constitute
                          a waiver of the essentiality of the Lessee's
                          obligations to make these payments;

             5.3.5        the Lessor's entitlement to recover damages as
                          specified above shall not be prejudiced or limited if:

                          5.3.5.1      the Lessee abandons or vacates the
                                       Premises;

                          5.3.5.2      the Lessor elects to re-enter the
                                       Premises or to determine this Lease;

                          5.3.5.3      the Lessor accepts the Lessee's
                                       repudiation of this Lease; or




                          5.3.5.4      the parties' conduct constitutes a
                                       surrender by operation of law;

             5.3.6        the Lessor shall be entitled to institute proceedings
                          to recover damages as specified above either before or
                          after any of the events or matters referred to in
                          paragraph 5.3.5 above;

             5.3.7        any conduct by the Lessor to mitigate damages shall
                          not of itself constitute acceptance of the Lessee's
                          breach or repudiation or a surrender by operation of
                          law; and

             5.3.8        nothing herein expressed or implied shall be construed
                          to mean that none of the other Lessee's Covenants may
                          be an essential term.

    5.4      DAMAGE TO THE PREMISES

             If the Premises or any part thereof at any time during the Term is
             resumed or taken for any public purpose by any competent authority
             or is declared unfit for occupation or ordered to be demolished by
             any competent authority or is destroyed or damaged by any risk
             insured against so as to render the same substantially unfit for
             the use and occupation of the Lessee or so as (in either case) to
             deprive the Lessee of substantial use of the same or so as (in the
             case of damage or destruction) to render the rebuilding or
             reconstruction of the Premises in its previous form impracticable
             or undesirable in the opinion of the Lessor, THEN:

             5.4.1        this Lease may be terminated without compensation by
                          either the Lessor or the Lessee by notice in writing
                          to the other PROVIDED THAT the Lessee shall only be
                          entitled to terminate this Lease if any policy of
                          insurance effected in respect of any damage or
                          destruction shall not have been vitiated or payment of
                          the policy moneys refused in consequence of some act
                          or default of the Lessee or any of the Lessee's
                          Employees or Visitors;

             5.4.2        any termination shall be without prejudice to the
                          rights of either party in respect of any antecedent
                          breach matter or thing;

             5.4.3        nothing herein expressed or implied shall be deemed to
                          impose any obligation upon the Lessor to rebuild or
                          reinstate the Premises or to make the same fit for use
                          and occupation of the Lessee;

             5.4.4        if any such resumption damage or destruction of the
                          Premises occurs the Rent and Outgoings or a
                          proportionate part thereof depending on the nature or
                          extent of the resumption destruction or damage shall
                          abate until the Premises shall have been rebuilt or
                          reinstated or made fit for the occupation and use of
                          the Lessee or until the Lease shall have been
                          terminated pursuant to the provisions of paragraph
                          5.4.1 above as the case may be. Until mutual agreement
                          between the Lessor and the Lessee as to the extent of
                          the abatement or until determined as provided herein
                          the Lessee shall continue to pay the Rent and
                          Outgoings in full and upon any agreement or
                          determination the Lessor shall refund free of interest
                          to the Lessee any Rent and Outgoings which according
                          to the agreement or determination has been overpaid.
                          If any dispute arises with respect to the extent of
                          the abatement it shall be determined by arbitration as
