|11.03 | Public Corporations
|----- | -------------------



A Transfer that occurs as the result of a change in control of a Tenant will not require the consent of Landlord if the shares are listed and traded on
any recognized stock exchange in Canada or the United States.



|11.04 | Landlords Termination Right
|----- | ----------------------------



If Tenant requests Landlords consent to a Transfer it will provide full particulars concerning the Transfer including without limitation, copies of
any written offer, agreement or draft agreement pertaining to the Transfer, payments and any other consideration to be made or provided by the proposed Transferee in consideration for the Transfer, and any other information concerning the proposed
Transfer or the financial and business history of the proposed Transferee that Landlord may require. Landlord will within fifteen (15) days after its receipt of the request for consent and all such information, notify Tenant that either
(i) it consents to the Transfer, or (ii) it elects to cancel this Lease as to the whole or part of the Premises affected by the proposed Transfer, or (iii) it does not consent to the Transfer. If Landlord elects to terminate this
Lease, Tenant may, by notice to Landlord given within seven (7) days after receipt of Landlords notice, withdraw its request for Landlords consent. In that case, Landlords election to terminate this Lease will be void. If
Tenant fails to withdraw its request for Landlords consent, Tenant will deliver, in accordance with the provisions of this Lease, vacant possession of the whole or the part, as the case may be, of the Premises affected by the termination on
the date specified in Landlords notice, which date will not be less than thirty (30) days nor more than one hundred and twenty (120) days after the date the notice is given or at the Landlords option on the date the proposed

|11.05 | Acceptance of Rent
|----- | ------------------



After a Transfer, Landlord may collect Rent from the Transferee and apply the net amount collected to the Rent payable hereunder but no acceptance by
Landlord of any payments by a Transferee constitutes a waiver of the requirement for Landlords consent to the Transfer or an acceptance of the Transferee nor will it release Tenant from its covenants and obligations under this Lease. Any
documents evidencing a Transfer may, at Landlords option, be prepared by Landlord or its solicitors.



|11.06 | Conditions of Consent
|----- | ---------------------



Any consent by Landlord to a Transfer will be subject to the following conditions:



(a) Tenant will pay to Landlord any money or other consideration (including without limitation, any amount payable by the
Transferee to Tenant in excess of the Annual Rent payable by Tenant under Article 4.01) from time to time paid by any Transferee to Tenant in connection with the Transfer;



19



---

( b) if Landlord requires, the Transferee shall execute an agreement directly with Landlord agreeing to
be bound by this Lease, and in the case of a sublease the Transferee shall waive any right to obtain relief from forfeiture, to obtain a direct lease from Landlord or to become the tenant of Landlord notwithstanding any statute or law that would
otherwise give those rights to sub-tenants;



( c) Tenant and
each Transferee will be bound by this Lease and any amendment of this Lease throughout the Term and any renewal or extension of the Term regardless of whether or when an amendment of this Lease is made; whether agreed to by Tenant or a Transferee,
and regardless of any surrender and new lease that is deemed at law to occur as the result of any amendment of this Lease. The liability of Tenant and each Transferee will continue as though Tenant and each subsequent Transferee had signed each
amendment of this Lease;



( d) Tenant shall pay any legal
costs incurred by Landlord in connection with documents relating to a Transfer or Landlords consent together with Landlords reasonable administrative charge for considering a request to consent and, as a condition of considering a
request for consent, Landlord may require payment of a reasonable deposit of at least five hundred dollars ($500.00) on account of its costs;



( e) if this Lease is disaffirmed, disclaimed, terminated, repudiated, or surrendered (each of these transactions being referred to as an Early
Termination) by any trustee in bankruptcy of a Transferee, by any court appointed officer, or by a Transferee in connection with any insolvency proceedings, Tenant and any Transferee (except the bankrupt or insolvent Transferee) will be
considered, on notice from Landlord given within thirty (30) days after the Early Termination, to have entered into a lease with Landlord on the same terms and conditions as are contained in this Lease except that the term of the lease shall
commence on the date of the Early Termination and shall expire on the date this Lease would have expired but for the Early Termination; and



( f) no consent to a Transfer will be considered as a waiver of the requirement for Landlords consent in respect of a subsequent Transfer.

subtenants in the Premises or any part thereof. If this Lease is surrendered by operation of law or otherwise, Tenant will indemnify Landlord against all claims by subtenants or others claiming by or through Tenant in respect of any interest in this

payment of such money. After the giving of notice or the commencement of a suit, or after final judgment granting Landlord possession of the Premises, Landlord may receive and collect any sums of Rent and other amounts payable by Tenant under this
Lease, and the payment thereof shall not make ineffective any notice, or in any manner affect any pending suit or any judgment theretofore obtained.

restriction, any option to lease, any right of first refusal and any other pre emptive or collateral right, and nothing contained in this Article 13 .00 shall be construed to limit or impair any of Landlords rights of re-entry or eviction or

ARTICLE 19.00 DEFAULT



|19.01 | Interest and Costs
|----- | ------------------



Tenant shall pay to Landlord upon Landlords written demand interest at a rate equal to the lesser of Prime plus five percent (5%) per annum and

|19.02 | Right of Landlord to Perform Covenants
|----- | --------------------------------------



All covenants and agreements to be performed by Tenant under this Lease shall be performed by Tenant without any abatement of Rent. If Tenant fails to
perform any act on its part to be performed hereunder, and such failure continues for ten (10) days after notice thereof from Landlord, Landlord may (but shall not be obligated so to do) perform such act without releasing Tenant from any of its
obligations relative thereto. All sums paid or costs incurred by Landlord in so performing such acts under this Article 19.02, together with interest thereon at the rate set out in Article 19.01 and an administration fee of fifteen percent

insolvent debtors or becomes involved in voluntary or involuntary dissolution, winding-up or liquidation proceedings or if a receiver is appointed for all or part of the business, property, affairs or revenues of Tenant, or if Tenant makes a
proposal, arrangement or compromise with creditors;

chattels and equipment out of the Premises (other than in the normal course of its business) or ceases to conduct business from the Premises;



( e) Tenant fails to observe, perform and keep each of the covenants, agreements, provisions, stipulations and conditions herein contained to be observed,
performed and kept by Tenant (other than its covenant to pay Rent) and persists in such failure after ten (10) days notice by Landlord requiring that Tenant remedy, correct, desist or comply (or if any such breach would reasonably require
more than ten (10) days to rectify, unless Tenant commences rectification within the ten (10) day notice period and thereafter promptly, effectively and continuously proceeds with the rectification of the breach); or



(f) Tenant purports to effect a Transfer other than in compliance with the
provisions of this Lease, then and in any of such events, the full amount of the current months and the next ensuing three (3) months installments of Rent shall immediately become due and payable and Landlord may immediately
distrain for the same, together with any arrears then unpaid and at the option of Landlord, Landlord may terminate this Lease by giving notice thereof, and Landlord may without notice or any form of legal process whatsoever forthwith re-enter the
Premises, anything contained in any statute or at law to the contrary notwithstanding, and may expel all persons and remove all property from the Premises and such property may be removed and sold or disposed of by Landlord as it deems advisable or
may be stored in a public warehouse or elsewhere at the cost of Tenant without Landlord being considered guilty of trespass or conversion or becoming liable for any loss or damage which may be occasioned thereby, provided, however, that such
termination shall be wholly without prejudice to the right of Landlord to recover arrears of Rent and damages for any default by Tenant hereunder. Should Landlord at any time terminate this Lease by reason of any such event, then, in addition to any
other remedies it may have, it may recover from Tenant all damages it may incur as a result of such termination. If Landlord re-enters and terminates this Lease and Tenant fails to remove its property within ten (10) days after notice requiring
it to do so is given, Tenant will be deemed to have abandoned its property and Landlord will be entitled to retain it or dispose of it for Landlords benefit. Tenant expressly waives the provisions of Section 19(2) of the Commercial
Tenancies Act (Ontario) and any successor or replacement legislation or any similar legislation of the province in which the Building is situated.



|19.04 | Waiver of Exemption and Redemption
|----- | ----------------------------------



Notwithstanding anything contained in any statute now or hereafter in force limiting or abrogating the right of distress, none of Tenants goods,
chattels or trade fixtures on the Premises at any time during the Term shall be exempt from levy by distress for Rent in arrears, and upon any claim being made for such exemption by Tenant or on distress being made by Landlord this agreement may be



27



---

pleaded as an estoppel against Tenant in any action brought to test the right to the levying upon any such goods as are named as exempted in any such
statute, Tenant hereby waiving all and every benefit that could or might have accrued to Tenant under and by virtue of any such statute but for this Lease. Tenant hereby also expressly waives any and all rights of redemption granted by or under any
present or future laws if Tenant is evicted or dispossessed for any cause. In exercising its right to distrain, Landlord, in addition to the rights reserved to it, shall have the right:



( a) to enter the Premises by force or otherwise without being liable for any prosecution therefore;



( b) to change the locks on the Premises without re-entering the Premises or
terminating this Lease in order to prevent the removal of the property to be distrained; and



( c) to levy distress after sunset and before sunrise.

accelerated Rent as herein provided and damages including but not limited to (i) damages for the loss of Rent suffered by reason of this Lease having been prematurely terminated; (ii) the costs of reclaiming, repairing and re-leasing the
Premises; and (iii) legal fees and disbursements on a solicitor and his client basis.



|19.06 | Remedies Cumulative
|----- | -------------------



No reference to or exercise of any specific right or remedy by Landlord shall prejudice or preclude Landlord from exercising or invoking any other remedy
in respect thereof, whether allowed at law or in equity or expressly provided for herein. No such remedy shall be exclusive or dependent upon any other such remedy, but Landlord may from time to time exercise any one or more of such remedies
independently or in combination.



|19.07 | Collateral Rights
|----- | -----------------



Tenant acknowledges that any right of first refusal, option to lease, right of first offer or other right to lease and any exclusive use restriction or
similar restriction granted to it under this Lease is collateral in nature and not fundamental to this Lease. The remedies of Tenant in connection with any breach of such rights are limited to an action in damages and will not entitle Tenant to
treat any breach of such rights as a repudiation or fundamental breach of this Lease by Landlord.

manner as the execution of this Lease.



|20.08 | Construed Covenants and Severability
|----- | ------------------------------------



All of the provisions of this Lease are to be construed as covenants and agreements as though the words importing such covenants and agreements were used
in each separate Article hereof. Should any provision of this Lease be or become invalid, void, illegal or not enforceable, it shall be considered separate and severable from this Lease and the remaining provisions shall remain in force and be
binding upon the parties hereto as though such provision had not been included.

|20.10 | No Implied Surrender or Waiver
|----- | ------------------------------



No provision of this Lease shall be deemed to have been waived by Landlord unless such waiver is in writing signed by Landlord. Landlords waiver of
a breach shall not prevent a subsequent act, which would have originally constituted a breach, from having all the force and effect of any original breach. Landlords receipt of Rent with knowledge of a breach shall not be deemed a waiver of
any breach. Landlords failure to enforce against Tenant or any other tenant in the Building any of the Rules and Regulations shall not be deemed a waiver thereof. Nothing done by Landlord shall be deemed to be an acceptance of a surrender of
the Premises, and no agreement to accept a surrender of the Premises shall be valid, unless in writing signed by Landlord. The delivery of keys by Tenant to any of Landlords agents or employees shall not operate as a termination of this Lease
or a surrender of the Premises. No payment by Tenant, or receipt by Landlord, of

---

a lesser amount than the Rent due hereunder shall be deemed to be other than on account of the earliest stipulated Rent, nor shall any endorsement or
statement on any cheque or any letter accompanying any cheque, or payment as Rent, be deemed an accord and satisfaction, and Landlord may accept such cheque or payment without prejudice to Landlords right to recover the balance of such Rent or
to pursue any other remedy available to Landlord.



|20.11 | Application of Payments
|----- | -----------------------



Regardless of any instruction from Tenant, or any written direction or any endorsement on any cheque, transmittal letter or any other form of
communication purporting to direct otherwise, Landlord may apply any payment which it receives from Tenant against any amount owed to it by Tenant and if Landlord does not notify Tenant otherwise, each payment will be considered to be a payment on
account of the Rent or Rental Taxes that have been unpaid the longest.



|20.12 | Successors Bound
|----- | ----------------



Except as otherwise specifically provided, the covenants, terms, and conditions contained in this Lease shall apply to and bind the heirs, successors,
executors, administrators and assigns of the parties hereto as limited by this Lease.



|20.13 | Liability of Landlord
|----- | ---------------------



In addition to the limitation on liability in Articles 16.05, 17.02 and elsewhere in this Lease, the liability of Landlord hereunder shall be limited to
its interest in the Building from time to time. If there is more than one person constituting Landlord, the liability of each said person hereunder shall be several and be limited to its percentage interest in the Building.



|20.14 | Force Majeure
|----- | -------------



Notwithstanding any other provision of this Lease, if Landlord or Tenant is, in good faith, delayed or prevented from doing anything required by this
Lease, because of a strike, labour trouble, inability to obtain materials or services, power failure, restrictive governmental laws or regulations, riots, insurrection, sabotage, rebellion, war, act of God, or any other similar reason, that is not
the fault of the party delayed, the doing of the thing is excused for the period of the delay and the party delayed will do what was delayed or prevented within the appropriate period after the delay. The preceding sentence does not excuse Tenant
from payment of Rent or Landlord from payment of amounts that it is required to pay, in the amounts and at the times specified in this Lease.
