Failing agreement, the surveyor referred to in clause 3.4.6 shall determine an alternative mechanism. 3.4.6 If any dispute or question arises between the parties as to the amount of the Indexed Rent or the construction of this clause, or if the Landlord and the Tenant fail to reach agreement under clause 3.4.5, either party may require the matter to be decided by an independent surveyor. 3.4.7 The independent surveyor shall act as an arbitrator and clause 6.2 shall apply. 3.4.8 The surveyor can decide what the increase in the Index would have been had it continued on the same basis or, if he considers it appropriate, he can decide an alternative mechanism for setting the Principal Rent taking into account the purposes and intent of this clause for the review of the Principal Rent. 3.4.9 If the Principal Rent payable from the relevant Rent Review Date has not been ascertained by that date, the Tenant shall continue to pay the Principal Rent on account at the rate payable immediately before the relevant Rent Review Date until the Rent Day immediately following the ascertainment of the new Principal Rent.

76907807.1 11 following the modification or removal shall be a Rent Review Date. The provisions of this clause 3.4 shall then apply, without prejudice to the review due on the immediately following Rent Review Date. 3.4.11 Immediately after the ascertainment of the new Principal Rent, a memorandum of the new Principal Rent shall be prepared by the Landlord or its solicitors and signed by or on behalf of the parties to this lease in duplicate and attached to this lease and to the counterpart. 3.4.12 For the purpose of this clause 3.4, time shall not be of the essence. 4.

The Term shall then end (but without prejudice to the accrued rights of either party) and, subject to clause 6.1.4, the insurance money shall wholly belong to the Landlord. 6.1.4 If the sum insured has been increased, at the Tenant's request and cost, to include the rebuilding cost of any improvements to the Property made by the Tenant at the Tenant's cost and not under an obligation to the Landlord, then such increased part of the insurance money shall be payable to the Tenant. 6.1.5 Any dispute relating to this clause 6.1 shall be referred to arbitration. 6.1.6 If terminated pursuant to clauses 5.3.3(b), 5.3.4, 5.3.5(b) or 6.1.3 then the Landlord shall within fourteen days, refund to the Tenant the due proportion of any Principal Rent and other sums paid in advance by the Tenant in respect of any period falling after the day on which the Term ends. 6.2 Arbitration Where this lease requires any dispute to be referred to arbitration, it shall be referred to an independent chartered surveyor to be appointed jointly by the Landlord and the Tenant or (in the absence of a joint appointment) at the request of either the Landlord or the Tenant by or on behalf of the President for the time being of the Royal Institution of Chartered Surveyors.
