                    party at any time after the expiry of the said one year
                    period, to terminate the Sub-Lease and thereupon the rights
                    and obligations of the parties shall cease and have no
                    effect but without prejudice to any antecedent right or
                    claim arising hereunder.

EIGHTH

                    Period of the Sub-Lease:--

                    (a)  the rents payable under the Sub-Lease or the Revised

                         arrear and unpaid for fourteen days after becoming
                         payable (whether legally demanded or not), or

                    (b)  there shall be any material breach, non-performance or
                         non-observance by the Sub-Tenant of any of the
                         obligations and conditions contained in the Sub-Lease;
                         or

                    (c)  the Sub-Tenant passes a resolution to wind-up, enter
                         into liquidation or insolvency whether compulsory or
                         voluntary (save for the purpose of amalgamation or
                         reconstruction of a solvent company) or has a Receiver
                         or Administrator appointed of its undertaking or enters
                         into an arrangement or composition for the benefit of
                         its creditors, or suffers any diligence to be done or

                                         -8-

                    goods or being a firm shall be sequestrated; the Mid-
                    Landlord shall be entitled forthwith to terminate this Sub-
                    Lease and treat this Sub-Lease and all transmissions thereof
                    with all that has followed or can competently follow thereon
                    as void and null and that without the necessity of any
                    declarator, process of removal, or other procedure at law
                    and the Premises shall thereupon revert to the Mid-Landlord.
                    In such event it shall be lawful for the Mid-Landlord or
                    any person or persons duly authorised by the Mid-
                    Landlord on their behalf to enter upon the possession of the
                    Premises or any part thereof in name of the whole and to
                    eject the Sub-Tenant and occupiers and thereafter use,
                    possess and enjoy the same free of all claims by the Sub-
                    Tenant as if this Sub-Lease had never been granted without
                    prejudice to any right of action or remedy of the Mid-
                    Landlord in respect of the premature termination of the Sub-
                    Lease or of any antecedent breach by the Sub-Tenant of any
                    of the conditions contained in the Sub-Lease which irritancy
                    is hereby declared to be pactional and not penal and shall
                    not be purgeable at the bar; Provided that (ONE) in the case
                    of a breach which is capable of being remedied the Mid-
                    Landlord shall not be entitled to terminate this Sub-Lease
                    as aforesaid unless it shall first have given notice of the
                    breach to the Sub-Tenant prescribing a time which in the
                    opinion of the Mid-Landlord is reasonable in the
                    circumstances (such circumstances not including the
                    financial position of the Sub-Tenant) within which such
                    breach must be remedied and the Sub-Tenant shall have
                    failed to remedy the breach within the time prescribed in
                    the notice and declaring that where the breach is the
                    failure to pay any sum of money, a reasonable time shall be
                    a period of not less than fourteen days; (TWO) in the case
                    of the Sub-Tenant going into liquidation (other than for
                    reconstruction or amalgamation as aforesaid) or in the case
                    of a Receiver or Administrator being appointed the Mid-
                    Landlord shall not exercise such right of forfeiture on the
                    ground of liquidation or insolvency or appointment of a
                    Receiver or Administrator unless and



                                         -9-

                    until they have allowed the Liquidator, Receiver or
                    Administrator or interim or permanent trustee (as the case
                    may be) a period of six months in which to dispose of the
                    Sub-Tenant's interest in this Sub-Lease and shall only be
                    entitled to terminate this Sub-Lease if the Liquidator,
                    Receiver, Administrator or interim or permanent trustee as
                    the case may be shall have failed to dispose of the Sub-
                    Tenant's said interest at the end of said period provided
                    always that the Liquidator, Receiver or Administrator or
                    interim or permanent trustee shall accept and implement in
                    writing within twenty one days of the date of liquidation or
                    receivership or appointment of an interim or permanent
                    trustee as the case may be personal responsibility for
                    payment of the rent for the Premises and performance of all
                    the Sub-Tenant's obligations under this Sub-Lease whether
                    arising before or after the date of liquidation or
                    receivership or appointment of an interim or permanent
                    trustee as the case may be to the expiry of the said period
                    or, if earlier, the date of entry under the disposal of the
                    Sub-Tenant's interest in this Sub-Lease and it is hereby
                    expressly declared that the Mid-Landlord shall deal with any
                    request to consent to assign this Sub-Lease made by such
                    Liquidator, Receiver, Administrator or interim or permanent
                    trustee as the case may be in the same manner as if such
                    requests had been made by the Sub-Tenant.

NINTH
VALUE 
ADDED TAX      1.   Where there is a provision under the Sub-Lease for the Sub-
                    Tenant to pay any fees, costs, charges, commission,
                    remunerations, expenses or outlays the Sub-Tenant shall also
                    be responsible for payment of any Value Added Tax thereon
                    together with interest thereon from the date of the demand
                    (or, in the case of rent), from the date when same falls
                    due) until paid by the Sub-Tenant.

               2.   Without prejudice to the foregoing sub-paragraph, in the
                    event that Value Added Tax shall be chargeable on the Mid-
                    Landlord in respect of any supplies as defined in the Value
                    Added Tax Act 1983 (or any statutory modification or




                                         -10-

                    Sub-Tenant the Sub-Tenant shall in addition to any amounts
                    otherwise payable, pay to the Mid-Landlord the amount of the
                    Value Added Tax so chargeable.

               3.   Any rents and other sums payable under the Sub-Lease shall
                    (notwithstanding any present or future statutory provision
                    to the contrary) be exclusive of any Value Added Tax
                    chargeable thereon (whether or not chargeable as the result
                    of any change in the law and whether or not chargeable as
                    the result of the exercise by the Mid-Landlord the Sub-
                    Tenant or the Mid-Landlord and the Sub-Tenant jointly of any
                    option in respect of the charging of Value Added Tax).

TENTH
NOTICES        The provisions for notices contained in the Lease shall apply
               also under the Sub-Lease as if "the Mid-Landlord" had been
               substituted for "the Landlords" and "the Sub-Tenant" had been
               substituted for "the Tenants".
