“Review Date”		the 25th day of December 2012 and every anniversary of that date and the date which is one day before the date on which the Term would expire by effluxion of time (disregarding any statutory continuation thereof);

“Initial Charge”		£8,477.50 per annum;

“Index”		the Index of Retail Prices (All Items) published by H M Government or any equivalent index stated by H M Government to be the official successor to the Index of Retail Prices (All Items) PROVIDED that if the method of computation and/or the reference base of the Index shall materially change after the date of this Lease then the figure deemed to be shown in the Index for the purposes of this Lease after such change shall be the figure which would have been shown in the Index if the method of computation and/or reference base current at the date of this Lease had been retained, and any official reconciliation between such differing methods of computation or reference bases shall be binding on the parties to this Lease;

“Relevant Fraction”		a fraction of which the numerator is the figure of the Index published in the four weeks preceding the relevant Review Date and the denominator is the figure of the Index published in December 2011;

The Expert shall consider such matters submitted to him but shall not be fettered thereby and shall determine the Revised Charge in accordance with his own knowledge, judgment and opinion having regard to such matters as he may consider appropriate. The Expert’s decision shall (save as to any question of law) be final and binding on all matters referred to him under this Lease.

5. If after the date of this Lease it becomes impossible (because of any change in the methods used to calculate the Index, or for any other reason) to calculate the Revised Charge, then the Expert shall have full power to determine what the increase in the Index would have been had it continued on the same basis as is assumed to be available for the operation of this rent review or (if that determination shall also be impossible) shall determine a reasonable charge having regard to the purposes and intent of this Schedule.

1.2 “Utilities Charge” means the cost referred to in clause 3.2(c), calculated in accordance with this Schedule;

1.3 “Utilities Charge Period” means each period of 12 months commencing on 16 November falling wholly or partly within the Term (but only to the extent falling within the Term) provided that the Landlord may vary the Utilities Charge Period at its sole discretion at any time during the Term;

1.4 “End Date” means the date on which the Term expires or (if earlier) on which the Term is determined;

2. Subject to paragraph 8, the Landlord will, prior to each Utilities Charge Period (or on or prior to the commencement of the Term, in the case of the First Utilities Charge Period), submit to the Tenant a statement setting out the Estimated Utilities Charge for the forthcoming Utilities Charge Period.

3. The Tenant will pay the Estimated Utilities Charge to the Landlord by equal quarterly payments in advance on the usual quarter days, the first payment (being the due proportion for the period commencing on 16 November 2012 and ending on the day before the next quarter day hereafter) to be paid on or before the date of this Lease.

4. At the end of each Utilities Charge Period the Landlord shall procure that readings are taken and recorded from the Meters and the readings taken and recorded shall (subject to manifest error) be accepted by the Landlord and the Tenant. Should Meters not be installed the Landlord’s surveyor shall calculate (the Landlord’s surveyor’s determination to be conclusive) a just proportion fairly attributable to the Premises of the actual cost to the Landlord of supplying the relevant services to the Science Park during the relevant Utilities Charge Period and such proportion shall be the Utilities Charge for the relevant Utilities Charge Period.

5.3 the difference (if any) between the sums referred to in paragraphs 5.1 and 5.2.

6. If in respect of a Utilities Charge Period the Utilities Charge is more or less than the Estimated Utilities Charge received from the Tenant then any sum payable to or by the Landlord by way of adjustment (with the intent that the Tenant shall have paid the whole of the Utilities Charge to the Landlord in respect of the relevant Utilities Charge Period) will become due and shall be paid by the Tenant (within 14 days of delivery of the statement referred to in paragraph 5) or credited to the Tenant for the succeeding Utilities Charge Period (or paid to the Tenant in the case of the Final Utilities Charge Period) as the case may require.

7. The Tenant shall be liable only for the Utilities Charge up to and including the End Date but the provisions of this schedule shall otherwise continue to apply after the End Date.

8. The Landlord may, on prior written notice to the Tenant, vary the means by which the Utilities Charge is charged to the Tenant provided that such variation is fair, proper and in the interests of good estate management.

9.1 Within one month after delivery to the Tenant of the statement referred to in paragraph 5 (time being of the essence) the Tenant may request the Landlord to provide (and the Landlord will promptly provide) to the Tenant all vouchers and invoices which the Tenant shall reasonably need in order to satisfy itself as to the accuracy of the Utilities Charge in accordance with this Schedule.

9.2 Within two months after delivery of the statement referred to in paragraph 5 (time being of the essence) the Tenant may challenge it on the ground that it contains errors or is otherwise incorrectly drawn by giving to the Landlord notice to that effect but only if it has first made full payment of any amount due from the Tenant under paragraph 6 and if so:

(a) both parties must endeavour to resolve the relevant issue; but if they cannot do so;

(b) the issue in dispute may be referred by either party to the determination of an independent surveyor being such a person as is mentioned in clause 5.3(a) and who shall be appointed as mentioned in clause 5.3(b) and clauses 5.3(c), 5.3(d), 5.3(e), 5.3(f) and 5.3(g) shall also apply and the independent surveyor’s determination shall be final and binding on the parties Provided that if and whenever any person so appointed shall die, be adjudged bankrupt or become of unsound mind or if both the Landlord and the Tenant shall serve upon such person written notice that in their opinion he has unreasonably delayed making such determination such person shall ipso facto be discharged and be entitled only to his reasonable expenses prior to such discharge and another such independent surveyor shall be appointed to act in his place;

(c) any adjustments to the statement required to be made in consequence of the determination of the independent surveyor shall be made and any sum payable to or by the Landlord shall immediately be paid (with interest in respect of the period during which the relevant amount has been underpaid, such interest to be at the base rate for the time being of Barclays Bank PLC or, in the event of such rate ceasing to be published, at such equivalent rate as the Landlord shall notify to the Tenant) or allowed as appropriate;

but if not the Tenant’s right of challenge to that statement shall lapse.
