ARTICLE 6

REPAIR AND DAMAGE AND DESTRUCTION

     The Lessor and the Lessee further covenant and agree as follows:

     Section 6.01 Lessor’s Repairs. The Lessor covenants with the Lessee, subject to Sub-section 6.03 (b) and Section 11.02 hereof and except for reasonable wear and tear, to keep in a good and substantial state of repair the exterior walls, roof, foundations, and bearing structure of the Building and the pipes, heating and air conditioning, plumbing and electrical wires installed by the Lessor.

     The Lessor shall repair and maintain the Building in good order, including but not limited to the drains, plumbing, heating, air-conditioning, ventilation, washrooms, janitor closets, elevators, escalators, ducts, telephone closets, stairways, the lighting of common areas, the mechanical and electrical systems, security system and the parking lot and catch basin.

     Section 6.02 Lessee’s Repairs The Lessee covenants with the Lessor:

     (a) subject to Sub-section 6.03(b) and except for reasonable wear and tear and Insured Damage, aged, except where the latter is caused by the Lessee, its agents, employees, invitees or licensees, to keep in good and substantial state of repair and decoration, including repainting and cleaning of drapes and carpets at reasonable intervals as needed, the Leased Premises including all Leasehold Improvements and all trade fixtures therein and all glass therein other than (subject to Sub-section 6.02 (d) hereof) perimeter windows on floors above the Ground Floor of the Building;

     (b) that the Lessor may from time to time enter and view the state of repair, and that the Lessee will repair according to notice in writing;

     (c) that if any part of the Building including without limitation, the structure or the structural elements of the Building, or the systems for interior climate control or for the provision of utilities or services get out of repair, or become damaged or destroyed through the negligence or misuse of the Lessee or of its employees, invitees or others over whom the Lessee can reasonably be expected to exercise control, the expense of repairs or replacements thereto necessitated thereby shall be paid by the Lessee;

     (d) that the Lessee shall during the continuance of this Lease and at its expense repair and replace with as good quality and size any glass broken on the Leased Premises, and such obligation shall include outside windows and doors on the perimeter of the Leased Premises whenever such glass shall be broken by the Lessee, its servants, employees, agents or invitees; and

     (e) that the Lessee shall notify the Lessor immediately upon the Lessee becoming aware of any defect in the Leased Premises or of any other condition which may cause damage to the Leased Premises or the Building.

     Section 6.03 Abatement And Termination. It is agreed between the Lessor and the Lessee that:

(a) (i) In the event of partial destruction (as hereinafter defined) of the Leased Premises by fire, the elements or other cause or casualty, then in such event, if the destruction is such, in the opinion of the Lessor’s Architect, that the Leased Premises cannot be used for the Lessee’s business until repaired the rent shall abate until the repair has been made. If the destruction is such that, in the opinion of the Lessor’s Architect, the Leased premises may be partially used for the Lessee’s business while the repairs are being made, then the rent shall abate in the proportion that the part of the Leased Premises rendered unusable bears to the whole of the Leased Premises, PROVIDED ALWAYS that if the part rendered unusable exceeds one-half (1/2) of the area of the Leased Premises there shall be a total abatement of rent until the repairs have been made unless the Lessee, with the permission of the Lessor, in fact uses the undamaged part, in which case the Lessee shall pay proportionate rent for the part so used (being annual basic rent, electrical charges and Common Costs Escalation bearing the same proportion to the annual basic rent, electrical charges and Common Costs Escalation for the whole of the Leased Premises as the area in square feet of the part of the Leased Premises being used bears to the Rentable Area of the Leased Premises). “Partial Destruction” shall mean any damage to the Leased Premises less than total destruction, but which renders all or any part of the Leased Premises temporarily unfit for use by the Lessee for the Lessee’s business. A certificate of the Lessor’s Architect as to whether the whole or a part of the Leased Premises is rendered unusable, and certifying the extent of the part rendered unusable, shall be binding and conclusive upon both Lessor and Lessee for the purposes hereof. Provided that if the partial destruction is repaired within fifteen (15) days after the date of destruction, there shall be no abatement of rent.

     (ii) In the event of partial destruction (as hereinbefore defined) the Lessor shall repair and restore the Leased Premises according to the nature of the damage with all reasonable diligence, except for improvements installed by the Lessee which the Lessee shall repair and restore, in both cases, to substantially the condition the same were in immediately before such destruction occurred, but to the extent that any part of the Leased Premises is not reasonably capable of use by reason of damage which the Lessee is obligated to repair hereunder, any abatement of rent to which the Lessee is otherwise entitled hereunder shall not extend later than the time by which, in the reasonable opinion of the Lessor, repairs that the Lessee ought to have completed with reasonable diligence. Provided however that the Lessee shall pay for the cost of the repair and restoration of all destruction which is attributable to the wilful act or neglect of the Lessee, its servants or agents and in such a case, notwithstanding anything herein otherwise contained, there shall be no abatement of rent.

(b) (i) In the event of the total destruction (as hereinafter defined) of the Leased Premises by fire, the elements or other cause or casualty, then in such event this Lease shall terminate with effect from the date when such destruction

occurs. Thereupon the Lessee shall immediately surrender the Leased Premises and all its interest therein to the Lessor and the Lessee shall pay rent only to the time of such destruction, and the Lessor may re-enter and repossess the Leased Premises discharged of this Lease. Upon such termination, the Lessee shall remain liable to the Lessor for all sums accrued due to the Lessor pursuant to the terms hereof to the date of such destruction. ‘Total destruction” shall mean such damage to the Leased Premises that renders same unfit for use by the Lessee for the Lessee’s business and which cannot reasonably be repaired within six (6) months of the date of the destruction to the state wherein the Lessee could use substantially all of the Leased Premises for its business. A certificate of the Lessor’s Architect certifying that “total destruction” has occurred shall be binding and conclusive upon both the Lessor and the Lessee for the purposes here.

     (ii) Notwithstanding the foregoing provisions concerning total or partial destruction of the Leased Premises in the event of total or partial destruction of the Building of which the Leased Premises form a part (and whether or not the Leased Premises are destroyed) to such a material extent or of such a nature that in the opinion of the Lessor the Building must be or should be totally or partially demolished, whether to be re-constructed in whole or in part or not, then the Lessor may at its option (to be exercised within sixty (60) days from the date of destruction) give notice to the Lessee that this Lease is terminated with effect from the date stated in the notice. If the Lessee is able effectively to use the Leased Premises after the destruction, such date shall be not less than thirty (30) days from the date of the notice. If the Lessee is unable effectively to use the Leased Premises after the destruction, the date given in the notice shall be the date of destruction. Upon such termination, the Lessee shall immediately surrender the Leased Premises and all its interest therein to the Lessor and the rent shall abate and be apportioned to the date of termination and the Lessee shall remain liable to the Lessor for all sums accrued due pursuant to the terms hereof to the date of termination. The Lessor’s Architect shall determine whether the Leased Premises can or cannot be effectively used by the Lessee and his certificate thereon shall be binding and conclusive upon both Lessor and Lessee for the purposes hereof.

     (iii) In none of the cases aforesaid shall the Lessee have any claim upon the Lessor for any damages sustained by it nor shall the Lessor be obligated to rebuild the Building or any part thereof in accordance with the original plans and specifications therefor. No damages, compensation or claim whatsoever shall be payable by the Lessor for inconvenience, loss of business or annoyance or other loss or damage whatsoever arising from the occurrence of any such damage or destruction of the Leased Premises or of the Building and/or repair or restoration thereof.

The amount so estimated (which amount may be re-estimated from time to time during the calendar year) shall be payable in equal monthly installments in advance over the calendar year or broken portion of the calendar year in question, each such installment being payable on each monthly rental payment date provided in Article 3 hereof.

If the Lessee has underpaid such Common Costs Escalation and if any balance remains unpaid the Lessee shall pay such remaining balance within thirty (30) days of demand by the

Lessor. If for any reason the Common Costs Escalation is not finally determined within such calendar year or broken portion thereof, the parties shall make the appropriate re-adjustment when such Common Costs Escalation becomes finally determined. The obligation of the parties to observe or perform this covenant shall survive the expiration or other termination of the Term of this Lease.

     (c) Neither party may claim a re-adjustment in respect of the Common Costs Escalation based upon any error of estimation, determination or calculation thereof unless claimed in writing stating the particulars of the error prior to the expiration of two (2) years after the delivery of the Statement. If the Lessee disputes the accuracy of the Statement and the Lessee and Lessor fail to settle the matter within a reasonable period, the matter shall be referred by the Lessor to its independent accountant for prompt decision. Any report of the Lessor’s accountant (who may be the Lessor’s Internal auditor or accountant) as to the Common Costs Escalation shall be conclusive as to the amount thereof for any period to which such report relates.
