General. Except as otherwise provided in this Grant Agreement, the Options shall vest and become exercisable in accordance
with the vesting schedule set forth in the Notice of Grant, provided that the Participant remains in the Employment of the Corporation

in whole or in part until the earlier of (i) the Expiration Date set forth in the Notice of Grant, and (ii) the end of the applicable

Termination due to death or Disability, (i) the Participant's outstanding Options that have become Vested prior to the Participant’s
Termination due to death or Disability shall continue to be exercisable during the twelve (12) month period following the Participant’s
date of Termination due to death or Disability Date, and (ii) the Participant’s outstanding Options that are unvested on the Participant’s
date of Termination due to death or Disability shall be forfeited.

Resignation or Termination without Cause. Notwithstanding the vesting schedule set forth in the Notice of Grant, in the
event of Participant’s Termination due to resignation (including the voluntary withdrawal of services by the Participant who is
not an employee under Applicable Law) or Termination without Cause (including by way of constructive dismissal), (i) the Participant's
outstanding Options that have become Vested prior to the Participant’s Termination shall continue to be exercisable during the ninety
(90) day period following the Participant’s Termination, and (ii) the Participant’s outstanding Options that are unvested
on the Participant’s Termination shall be forfeited.

(d)

unvested Options granted to the Participant shall be immediately forfeited and cancelled, without any consideration as of the Termination.

(e)         
Change In Control. Notwithstanding the vesting schedule set forth in the Notice of Grant, the Options shall be subject to
the applicable provisions of the Plan in the event that a Change in Control occurs while the Participant is Employed.

    	  

    	 

    

3.           
Forfeiture. For greater certainty, the Participant shall have no right to receive Shares or a cash payment, as compensation,
damages or otherwise, with respect to any Options that do not become Vested, that have been forfeited, or that are not exercised before
the date on which the Options expire, whether related or attributable to any contractual or common law entitlements or otherwise.

4.           
Definitions.

For purposes of this Grant
Agreement,

(a)         
“Disability” means (i) subject to (ii), the Participant’s physical or mental incapacity that prevents
him/her from substantially fulfilling his or her duties and responsibilities on behalf of the Corporation or, if applicable, a Subsidiary
of the Corporation as determined by the Board and, in the case of a Participant who is an employee of the Corporation or a Subsidiary
of the Corporation, in respect of which the Participant commences receiving, or is eligible to receive, disability benefits under the
Corporation’s or Subsidiary’s long-term disability plan, or (ii) where the Participant has a written employment agreement
with the Corporation or a Subsidiary of the Corporation, “Disability” as defined in such employment agreement, if applicable.

(b)         
“Employment” means (i) the Participant’s rendering of services to the Corporation of a Subsidiary of the
Corporation (excluding services exclusively as a Director, and including as a Service Provider), or (ii) the Participant is not actively
rendering services to the Corporation or a Subsidiary of the Corporation due to vacation, temporary illness, maternity or parental leave
or leave on account of Disability or other authorized leave of absence. The terms “employ” and “employed” shall
have their correlative meanings.

(c)          
“Termination” means (i) the termination of the Participant’s Employment with the Corporation or a Subsidiary
of the Corporation (other than in connection with the Participant’s transfer to Employment with the Corporation or another Subsidiary),
which shall occur on the date on which the Participant ceases to render services to the Corporation or Subsidiary, as applicable, whether
such termination is lawful or otherwise (including, without limitation, by reason of resignation, death, frustration of contract, termination
for cause, termination without cause, or constructive dismissal), without giving effect to any pay in lieu of notice (paid by way of lump
sum or salary continuance), severance pay, benefits continuance or other termination-related payments or benefits to which the Participant
may be entitled pursuant to the common law or otherwise (except as may be expressly required to satisfy the minimum requirements of applicable
employment or labour standards legislation), but, for greater certainty, the Participant’s absence from active work during a period
of vacation, temporary illness, maternity or parental leave, leave on account of Disability or any other authorized leave of absence shall
not be considered to be a “Termination”, and (ii) in the case of the Participant who does not return to active Employment
with the Corporation or a Subsidiary of the Corporation immediately following a period of absence due to vacation, temporary illness,
maternity or parental leave, leave on account of Disability or other authorized leave of absence, such cessation shall be deemed to occur
on the last day of such period of absence as approved by the Corporation or a Subsidiary of the Corporation; provided, in each case, that,
in the case of Options that are deferred compensation subject to Section 409A of the Code and that are issued to a US Taxpayer, the Termination
constitutes a “Separation of Service”, within the meaning of Section 409A of the Code, and “Terminated” and “Terminates”
shall be construed accordingly.

    	  

    	 

    

5.           
 Method of Exercise.

(a)         
A Vested Option may be exercised, in whole or in part, by delivering to the Corporation at its registered office an executed exercise
notice in the form set out in Schedule A hereto (the “Option Exercise Notice”) or by such other form or means as the
Board may permit or require (including via electronic means). This notice shall state the intention of the Participant or the Participant’s
legal personal representative to exercise the said Options and the number of Shares in respect of which the Options are then being exercised
(the “Exercised Shares”) and must be accompanied by payment in full of the Exercise Price under the Options which are
the subject of the exercise. Upon exercise of the Option by the Participant and prior to the delivery of such Exercised Shares, the Corporation
shall have the right to require the Participant to satisfy applicable federal, provincial, state or local income tax withholding requirements
and the Participant’s share of other applicable statutory withholdings in a method satisfactory to the Corporation.

(b)         
The Participant may satisfy payment of the Exercise Price and/or the applicable statutory withholding for the Options which are
the subject of the Option Exercise Notice (i) through the delivery of cash, wire, other method of payment acceptable to the Corporation,
(ii) by the Participant delivering to the Corporation a properly executed Option Exercise Notice together with irrevocable instructions
to a broker to promptly deliver to the Corporation cash or a check payable and acceptable to the Corporation to pay the aggregate Exercise
Price and/or statutory withholding amount, provided that in the event the Participant chooses to pay the aggregate Exercise Price as so
provided, the Participant and the broker shall comply with such procedures and enter into such agreements of indemnity and other agreements
as the Corporation shall prescribe as a condition of such payment procedure, or (iii) a combination of (i) and (ii) above.

(c)          
Notwithstanding the foregoing, no Exercised Shares shall be issued unless such exercise and issuance complies with the requirements
relating to the administration of stock option plans and other applicable equity plans under Canadian securities laws, U.S. state corporate
laws, U.S. federal and state securities laws, the Code, any stock exchange or quotation system on which the Shares are listed or quoted,
and the applicable laws of any foreign country or jurisdiction; assuming such compliance, for income tax purposes the Exercised Shares
shall be considered transferred to the Participant on the date the Option is exercised with respect to such Shares.

6.           
Covenants Agreement. It is a condition of the grant of the
Option that the Participant complies with any agreement between the Participant and the Corporation with respect to noncompetition, non-solicitation,
assignment of inventions and contributions and/or nondisclosure obligations of the Participant. The Option shall be subject to forfeiture
at the election of the Corporation in the event of a breach of such agreement by the Participant.

7.           
Taxes. By executing this Grant Agreement, Participant acknowledges
and agrees that Participant is solely responsible for the satisfaction of any applicable taxes that may be imposed on Participant that
arise as a result of the grant, vesting or exercise of the Option (including without limitation alternative minimum taxes and any taxes
arising under Section 409A of the Code), and that neither the Corporation nor the Board shall have any obligation whatsoever to pay such
taxes or otherwise indemnify or hold Participant harmless from any or all of such taxes.

8.           
Non-Transferability of Option. Unless otherwise consented
to in advance in writing by the Board in accordance with the Plan, the Option may not be transferred in any manner other than by testamentary
disposition by the Participant or the laws of intestate succession. The terms of

    	  

    	 

    

the Plan and this Grant Agreement shall be binding
upon the executors, administrators, heirs, successors and, if applicable, permitted assigns (as defined in Division 4 of National Instrument
45-106 Prospectus Exemptions) of the Participant.

9.           
Other Plans. No amounts of income received by the Participant
pursuant to this Grant Agreement shall be considered compensation for purposes of any pension or retirement plan, insurance plan or any
other employee benefit plan of the Corporation or its subsidiaries, unless otherwise expressly provided in such plan.

10.         
No Guarantee of Employment. The Participant acknowledges
and agrees that the right to exercise the Option pursuant to the exercise schedule hereof is earned only by continuing Employment (and
not through the act of being hired, being granted an option or purchasing Shares hereunder). The Participant further acknowledges and
agrees that this Grant Agreement, the transactions contemplated hereunder and the exercise schedule set forth herein do not constitute
an express or implied promise of continued Employment for the exercise period or for any other period, and shall not interfere with the
Participant’s right or the right of the Corporation or its Subsidiaries to terminate the Participant’s Employment at any time,
with or without Just Cause, subject to the terms of any written employment agreement that the Participant may have entered into with the
Corporation or any of its Subsidiaries.

11.         
Entire Agreement. The Plan is incorporated herein by reference.
The Plan and this Grant Agreement constitute the entire agreement of the parties with respect to the subject matter hereof and supersede
in their entirety all prior undertakings and agreements of the Corporation and the Participant with respect to the subject matter hereof,
and may not be modified adversely to the Participant’s interest except by means of a writing signed by the Corporation and the Participant.
In the event of any conflict between this Grant Agreement and the Plan, the Plan shall be controlling.

12.         
Governing Law. This grant agreement and actions taken hereunder
shall be governed by and construed in accordance with the laws of the province of Ontario, without reference to the principles of conflict
of laws, and the federal laws of Canada, as applicable.

13.         
Opportunity for Review. Participant and the Corporation agree
that the Option is granted under and governed by the terms and conditions of the Plan and this Grant Agreement. The Participant has reviewed
the Plan and this Grant Agreement in their entirety, has had an opportunity to obtain the advice of counsel prior to executing this Grant
Agreement and fully understands all provisions of the Plan and this Grant Agreement. The Participant hereby agrees to accept as binding,
conclusive and final all decisions or interpretations of the Board upon any questions relating to the Plan and this Grant Agreement. The
Participant further agrees to notify the Corporation upon any change in the residence address indicated herein.

14.         
Electronic Acceptance. The Participant shall be deemed to
have accepted and agreed to the terms and conditions of this Grant Agreement by accepting the Grant Agreement by such electronic means
as the Corporation may permit.

accepts the Premises from the Landlord for the Term, subject to the terms, conditions, obligations and rights contained in this Lease. In addition, the Landlord hereby grants to the Tenant a non-exclusive
licence throughout the Term to the benefit or use (as may be appropriate) of those Common Areas which provide access to the Premises or which are generally made available to all tenants in the Building, in common with other tenants of the Building
and with all others entitled thereto, subject to the terms and conditions of this Lease. Notwithstanding the foregoing, nothing shall prevent the Landlord from restricting the Tenant’s use of Common Areas that are not required for ingress to or

this Lease constitutes a sub-sub-sublease and is subject and subordinate to the Master Leases.

measurer at Landlord’s cost in accordance with the Measurement Standard within six (6) months of the Commencement Date. The rentable area shall be amended in accordance with such measurement, the parties making any necessary adjustments to Rent
paid to date to reflect the proper rentable area, and the Premises shall not be re- measured thereafter unless the physical dimensions of the Premises are altered, in which case they shall be remeasured in

	2.2	 Term and Renewal and Termination Rights. 

 

	 	(a)	 The term of this Lease is for Fifteen (15) years commencing on the Commencement Date and ending on the
last day of the fifteenth (15th) Rental Year (the “Term”) and is being entered to between the Tenant and the Landlord for the construction by Landlord of a turnkey cGMP facility
for the production of radiopharmaceuticals at the Premises. The Landlord is responsible for ensuring the Landlord’s Work meets the timelines required by the Design Summary Chart and thus ensuring that Tenant is able to comply with the
manufacturing commitments made with third party customers by the Tenant in memoranda of understanding, letters of intent, or commercial agreements. The Commencement Date will be five days following satisfaction of the Turnover Condition, provided
that the following have been delivered to the Tenant by the Landlord prior to the date thereof: i) Landlord has provided the written consent, recognition and non-disturbance agreement executed by any other
Person that may be required to allow the Tenant’s uses as set out in this Agreement in accordance with Section 2.3 below, including the Master Lease NDAs (as hereinafter defined); ii) the parties have signed the Service Agreement by
September 1, 2021; and iii) the Landlord and Tenant have confirmed that there are no known Material Deficiencies in the Landlord’s Work (collectively, the “Preconditions”). For clarity, in accordance with Section 5.3,
the Fixturing Period shall commence upon the Commencement Date and until the Fixturing Period expires no Gross Rent or Additional Rent shall be payable. 

  

	 	(b)	 The Tenant shall have the right to terminate this Lease upon not less than twelve (12) months prior
written notice to the Landlord (the “Termination Right”). If the Tenant exercises the Termination Right and the termination date is any time on or after the 5th anniversary of the Commencement Date, the Tenant’s exercise of the
Termination Right shall be without penalty and without the obligation to pay any additional amounts to the Landlord. Where the Tenant exercises its Termination Right and pursuant thereto the Lease terminates prior to the fifth anniversary of the
Commencement Date, then the Tenant shall pay to Landlord an annual amount equal to $11.00 per square foot of the Premises calculated on a per month basis and multiplied by the lesser of i) the number of months remaining until ten (10) complete
years have elapsed since the Commencement Date; and ii) the number of months before the Landlord relets the total Premises to another tenant, the Landlord covenanting to use commercially reasonable efforts to relet the Premises to another tenant
following such termination. 

  

	 	(c)	 Tenant shall have the right to extend the Term of the Lease with respect to the Premises upon the terms and
conditions set forth in this Section 2.2(c). 

 12 
  

 
  

	 	(i)	 Tenant may extend the Term of the Lease for a single extension term of five (5) years (the
“Extension Term”) by delivering written notice of such extension to Landlord no earlier than eighteen (18) months and no later than twelve (12) months prior to the expiration of the original Term. Such Extension Term shall
commence immediately upon the expiration of the original Term and upon exercise of any such extension option the “Expiration Date” of the Term shall automatically become the last day of the Extension Term. 

 

	 	(ii)	 Base Rent for the Extension Term shall be the Extension Fair Market Rate (hereinafter defined) multiplied by
the rentable square feet in the Premises as of the commencement date of the Extension Term. For purposes hereof “Extension Fair Market Rate” means the fair market rental rate per square foot of rentable area that would be agreed
upon between a landlord and a tenant for a comparable lease extension for comparable space in a comparable laboratory and research and development building as to location, quality, age and reputation and a comparable term, assuming or taking into
consideration all then relevant factors. 

  

	 	(iii)	 Within fifteen (15) days after Landlord receives notice from Tenant that Tenant is exercising the
extension option, Landlord shall send written notice to Tenant specifying the Extension Fair Market Rate as determined by Landlord and, within fifteen (15) days after receipt of Landlord’s notice, Tenant shall give Landlord written notice
of Tenant’s acceptance or challenge of Landlord’s determination of the Extension Fair Market Rate; provided, however, that if Tenant fails to respond within such fifteen (15) day period, Tenant shall be deemed to not have
accepted Landlord’s determination of the Extension Fair Market Rate, and Landlord and Tenant shall endeavor to reach an agreement as to the Extension Fair Market Rate within thirty (30) days after the latter of the aforementioned fifteen
(15) day periods. Unless Landlord and Tenant agree in writing upon the Extension Fair Market Rate, Landlord and Tenant shall not be deemed to have agreed upon the Extension Fair Market Rate. 

 

	 	(iv)	 If Landlord and Tenant are unable to agree upon the Extension Fair Market Rate within the aforementioned time
period, then within thirty (30) days thereafter, Landlord and Tenant shall each submit to the other their written statement of the Extension Fair Market Rate and any supporting documentation that the submitting party desires to deliver. Within
ten (10) days after such thirty (30) day period, Landlord and Tenant shall appoint a real estate broker having a minimum of ten (10) years’ experience in the Hamilton/Greater Hamilton/Toronto Area commercial or life sciences
leasing market who shall select either Landlord’s determination or Tenant’s determination, whichever the broker finds more accurately reflects the Extension Fair Market Rate. The broker shall be instructed to notify Landlord and Tenant of
such selection within ten (10) days after such broker’s appointment. The broker shall have no power or authority to select any Extension Fair Market Value other than an Extension Fair Market Value

Tenant are unable to timely agree upon the appointment of the broker, Landlord shall submit to Tenant the names of three (3) qualified brokers who have not been employed by Landlord or its affiliates during the then past two (2) years and
Tenant shall have ten (10) days after receiving such names to notify Landlord of which of the three (3) brokers Tenant selects to determine the Extension Fair Market Rate. If Tenant fails to timely notify Landlord of Tenant’s
selection, Landlord shall have the right to unilaterally appoint the broker. The fee and expenses of the broker shall be split equally by Landlord and Tenant. If Landlord and Tenant are unable to agree upon the Extension Fair Market Rate within the
aforementioned time period, then within thirty (30) days thereafter, Landlord and Tenant shall each submit to the other their written statement of the Extension Fair Market Rate and any supporting documentation that the submitting party desires
to deliver. Within ten (10) days after such thirty (30) day period, Landlord and Tenant shall appoint a real estate broker having a minimum of ten (10) years’ experience in the Hamilton/Greater Hamilton/Toronto Area commercial or
life sciences leasing market who shall select either Landlord’s determination or Tenant’s determination, whichever the broker finds more accurately reflects the Extension Fair Market Rate. The broker shall be instructed to notify Landlord
and Tenant of such selection within ten (10) days after such broker’s appointment. The broker shall have no power or authority to select any Extension Fair Market Value other than an Extension Fair Market Value submitted by Landlord or
Tenant or to modify any of the provisions of this Lease, and the decision of the third arbitrator shall be final and binding upon Landlord and Tenant. If Landlord and Tenant are unable to timely agree upon the appointment of the broker, Landlord
shall submit to Tenant the names of three (3) qualified brokers who have not been employed by Landlord or its affiliates during the then past two (2) years and Tenant shall have ten (10) days after receiving such names to notify
Landlord of which of the three (3) brokers Tenant selects to determine the Extension Fair Market Rate. If Tenant fails to timely notify Landlord of Tenant’s selection, Landlord shall have the right to unilaterally appoint the broker. The
fee and expenses of the broker shall be split equally by Landlord and Tenant. 

  

	 	(v)	 Except as otherwise set forth in this Section 2.2(c), Tenant’s lease of the Premises for the
Extension Term shall be upon the same terms and conditions as are applicable immediately prior to the expiration of the original Term, except that Tenant will not have any further right to extend the Term of the Lease beyond the Extension Term.
Until the Extension Fair Market Rate is settled or determined, and provided the Tenant has duly elected to exercise the Extension Term as aforesaid, the Tenant shall continue to pay Gross Rent at the rate existing at the end of the Initial Term, to
be adjusted within fifteen (15) days following settlement or determination of the Extension Fair Market Rate.

	 	(d)	 Landlord reserves the right to appeal assessments or apply for a reduction or reclassification of any Taxes,
provided that Tenant shall continue to pay all Taxes as invoiced under Section 3.4(b) above pending any such appeal or application. Landlord agrees to use its best efforts to seek a ruling from Municipal Property Assessment Corporation and/or
City of Hamilton within the first year of the Term to investigate if the Tenant is entitled to any partial or full exemption, credit or rebate of Taxes. 

  

	 	(e)	 Notwithstanding the invoice generated and delivered to the Tenant under Section 3.4(b), the amount of
Taxes payable to the Landlord may be estimated by the Landlord for such period as the Landlord reasonably determines from time to time, and the Tenant agrees to pay to the Landlord the amounts so estimated in equal installments in advance on the
first day of each month during such period. Notwithstanding the foregoing, when invoices for all or any portion of such amounts are received, the Landlord may bill the Tenant for the Taxes and the Tenant shall pay the Landlord such amounts so billed
after crediting against such amount any monthly payments of estimated Taxes previously made by the Tenant. 

  

	 	(f)	 Within 180 days after the end of the period for which estimated payments have been made, the Landlord shall
submit to the Tenant a statement from the Landlord setting forth the actual amounts payable by the Tenant on account of Taxes along with reasonable back-up materials and documents requested by the Tenant. If
the amount the Tenant has paid is less than the amount due, the Tenant shall pay such deficiency forthwith. If the amount paid by the Tenant is greater than the amount due, the amount of such excess may be retained by the Landlord to be credited to

(the “Post-Lease Royalty Payment”) until the aggregate of the Royalty Payments and Post-Lease Royalty Payments reaches five million dollars ($5,000,000).

below or due to any default of the Landlord hereunder, this Section 3.7 shall not merge upon termination of the Lease but shall survive the termination of this Lease. 

 

	3.8	 Rent Past Due. All Rent past due shall bear interest from the date on which the same became due until
the date of payment at the prime rate of CIBC plus 1% per annum.

and the Tenant that this is a gross lease and, except as expressly provided for herein and the Services Agreement, the Tenant shall not be obligated to pay any amounts in respect of the lease of the Premises above and beyond the Gross Rent and any
costs incurred by the Landlord in carrying out Landlord’s obligations hereunder or under the Services Agreement shall be at Landlord’s sole cost. Except as set out herein or in the Services Agreement, the Tenant will not be responsible for
any costs payable pursuant to the Master Leases. Unless expressly stated herein or in the Services Agreement to the contrary, any costs incurred by the Tenant in carrying on the Tenant’s obligations hereunder or under the Services Agreement
shall be the Tenant’s costs.

	3.10	 Utilities, Etc. The Landlord shall provide heating, ventilation and air conditioning (“HVAC”)

The Landlord will provide and permit the Tenant to use the electricity, domestic water, sewage disposal and other utility services serving the
Building in such quantities as are reasonably required to carry on the Use. The Landlord covenants that the electricity, gas, domestic water and sewage disposal and other utility services servicing the Premises will be sufficient for Tenant to carry
on the Use and consistent with the Schematic Design Specifications Report. 
 The Landlord shall not be responsible for any interruption or
discontinuance of any private or public utility services. The Landlord shall not be in breach of its covenant for quiet enjoyment or liable for any loss, costs or damages, whether direct or indirect, incurred by the Tenant due to any interruption or
discontinuance of any such utility services, but the Landlord shall co-operate with the Tenant and use commercially reasonable efforts to restore the services, utilities or systems so stopped, interrupted or
reduced as soon as reasonably possible. 
  

	3.11	 Telecommunication Services. The Landlord represents and warrants that on the Commencement Date the
Premises will be able to connect to a fibre internet connection from Metro Loop, without such connection passing through a firewall of the Landlord, Gore, MIP, FLIT or FLWR, which fibre connectivity will be maintained by the Landlord throughout the
Term, subject to interruptions not caused by the negligence or willful misconduct of the Landlord. In the event of a disruption or cessation of telecommunications services to the Premises, the Landlord shall use commercially reasonable efforts to
assist the Tenant in restoring such services, or, if due to the fibre connection for which Landlord is responsible for maintaining, to restore same within a commercially reasonable time. Tenant shall be responsible for the costs of connecting its
equipment, trade fixtures and telecommunications lines and wiring to such fibre connection. The Tenant shall be solely responsible for arranging for the provision of, and the costs of, all telecommunications services to the Premises.

ARTICLE 4 – MAINTENANCE, REPAIRS AND ALTERATIONS 
  

	4.1	 Landlord’s Repair. 

 22 
  

 
  

	 	(a)	 Except as otherwise specifically provided in this Lease, the Landlord shall not be obliged in any manner
whatsoever to maintain, improve, repair or replace any part of the Premises, or to construct any improvements and facilities in connection therewith, or to do or cause to be done any act or thing on or in connection with the Premises so as to render
them fit or suitable or more convenient for the purposes of the Tenant or any Person having use or occupancy thereof. 

  

	 	(b)	 If the Tenant fails to carry out any maintenance or repair required to be carried out by it pursuant to this
Lease, and to the reasonable satisfaction of the Landlord, within 30 days of notice from the Landlord, the Landlord may at its option, but without any obligation, carry out or cause to be carried out such maintenance or repair, without any liability
for any damage which may result to the Tenant’s property or business by reason thereof, provided Landlord uses commercially reasonable means to prevent the disruption to Tenant’s use of the Premises during such period of maintenance or
repair. The cost of such work shall be paid by the Tenant to the Landlord within thirty (30) days following written demand and collected as Additional Rent. 

 

	 	(c)	 Notwithstanding anything to the contrary herein, in the event of an emergency to health and safety of Users,
the Landlord, the Tenant or the structural integrity of the Building, the Landlord may re-enter the Premises without notice to effect, but only to the extent reasonably required to prevent, cease or repair,
the defect that constitutes the emergency and only to the extent necessary to stabilize same so it is no longer an emergency. Thereafter, the balance of this Lease with respect to entry and repair shall apply. 

 

	 	(d)	 The Landlord shall effect all maintenance, repairs and replacements required to keep or cause to be kept the
following in good condition and repair: (i) all Common Areas and Building Systems of the Building; (ii) the roof, roof membrane, windows, foundations, steel columns, steel deck, concrete slab floors, walls, columns and other structural
elements of the Building, fixtures annexed to the Building that were not installed by the Tenant and are not intended to be removed by the Tenant; (iii) the master utility meters on the Premises; each as required from time to time in to
maintain the Building and Common Areas to the standard of a first-class commercial building. The costs of same shall be paid by the Landlord provided that they may be charged to the Tenant where the maintenance, repair or replacement was required
due to the negligence or willful misconduct of the Tenant or the Tenant’s failure to comply with this Lease and in accordance with the Services Agreement. 

 

	4.2	 Maintenance and Repair by the Tenant. Subject to the Landlord’s obligations herein, including in
Section 4.1(d), the Tenant shall, at its sole cost, repair and maintain the Premises and the Leasehold Improvements including: 

  

	 	(a)	 keeping the Premises clean and tidy at all times; and, 

 

	 	(b)	 adhere to the Landlord’s Health and Safety Manual, as amended from time to time; 

 23 
  

 
  

 Subject to the balance of this Section 4.2, and only to the extent that the repairs
relate to a requirement of the Tenant to adhere to a standard for cGMP or other 
 specific regulatory requirement directly related to its
specific use of the Premises, and provided that repairs do not impact those portions of the Building, the structure or Building Systems Landlord is responsible for repairing pursuant to Section 4.1(d), the Landlord will permit the Tenant to
effect such repairs within the Premises, provided all reasonable particulars of the repair, the personnel effecting the repairs, the cost, the proposed work plan and any warranty information is provided to the Landlord in advance of commencing same.
In all other circumstances, such repairs and maintenance shall be performed by the Landlord or its contractor/project manager to a standard consistent with the nature and condition of the Building as at the Commencement Date and subject to
Article 9 of this Lease. Tenant shall communicate to Landlord promptly all needed repairs and maintenance and Landlord shall have a right upon not less than 48 hours written notice to inspect the Premises to confirm its state of repair. 

 

	4.3	 Approval of Tenant’s Alterations. 

 

	 	(a)	 Due to the nature of the Tenant’s business, the Tenant may need to make Alterations to the Premises or the
Building Systems therein from time to time to meet changing business conditions or to remain cGMP compliant. No Alterations shall be made to the Premises or Building Systems or Leasehold Improvements therein without the Landlord’s prior written
approval of same and the Tenant’s plans and drawings for such Alterations, which approval shall not be unreasonably withheld, delayed or conditioned. Notwithstanding the foregoing, the Tenant shall be permitted to effect Alterations for the
purpose of changing business conditions or to remain cGMP compliant without the Landlord’s prior written approval where the Alterations are limited solely to modifying or moving Trade Fixtures or the Tenant’s equipment (excluding Leasehold
Improvements), in a manner that does not adversely affect the Building Systems or structural elements of the Building and which do not, in the aggregate exceed the cost of Ten Thousand Dollars ($10,000) to complete. Alterations for any other
purpose, including to accommodate Assignments, shall be governed by 4.3(b), (c), (d), (e) and (f). 

  

	 	(b)	 Except as otherwise permitted herein, when the Tenant desires to make an Alteration, the Tenant shall submit to
the Landlord details of the proposed Alteration including appropriate drawings and specifications. The Landlord shall review Tenant’s proposal in an expeditious fashion, which review shall include the review of same by FLWR, and deliver a
written decision to the Tenant in not more than ten (10) Business Days following receipt of the proposed Alteration. The Landlord’s reasonable out-of-pocket
costs of reviewing and approving all such proposed Alterations, including by the Architect or engineer as the case may be, shall be reimbursed by the Tenant, not to exceed $2,500. 

 

	 	(c)	 All Alterations shall be performed: 

 

	 	(i)	 at the sole cost of the Tenant; 

 24 
  

 
  

	 	(ii)	 by contractors on a pre-approved list of Tenant and Landlord approved
contractors or otherwise approved in writing by the Landlord and the Tenant, both parties acting reasonably; it is acknowledged by the parties that where an Alteration requires special knowledge, training or certification in handling, exposure and
treatment of radioactive materials, that, acting reasonably, the Tenant shall approve of all such contractors retained for the Alteration; 

  

	 	(iii)	 in a good and workmanlike manner; 

 

	 	(iv)	 in accordance with drawings and specifications approved by the Landlord, as applicable; 

 

	 	(v)	 in accordance with all Applicable Laws and the Landlord’s Health and Safety Manual, provided that no
Alterations shall be commenced prior to the Tenant obtaining, at its sole cost, a building permit and any other permits required by any governmental authority having jurisdiction; 

 

	 	(vi)	 subject to the reasonable regulations and inspection of the Landlord; and 

 

	 	(vii)	 At the option of the Landlord, after the drawings and specifications therefor that impact the base building
mechanical, electrical environmental and structural components have been reviewed (pursuant to Section 4.3(b)) by the Landlord’s base building mechanical, electrical, environmental and structural engineering consultants where required to
ensure compatibility of the Alterations with the Building Systems or structure of the Building. 

  

	 	(d)	 The Tenant shall not place anything on or make any openings in the roof without the prior written consent of
the Landlord, which may be granted or withheld at the Landlord’s sole discretion. On the expiration of the Term or earlier termination of this Lease, the Tenant shall repair any damage caused to the Building as a result of having placed
anything on or having made openings in or having attached anything to the roof, failing which the Landlord may, without obligation, repair the damage and charge the Tenant the costs of same and collect same as Additional Rent. 

 

	 	(e)	 All Alterations shall be pursued diligently to completion. Where it appears to the Landlord that the
Alterations are not being pursued as required, the Landlord may require the Tenant to develop a timeline for completing same and, once approved by the Landlord, the Tenant’s shall adhere to such timeline. 

 

	 	(f)	 In any event, the Tenant agrees to ensure, prior to commencement of any work or Alterations, that all of the
Tenant’s contractors who perform work to the Premises and/or Building as required, must: 

  

	 	(i)	 agree to be bound by the procedures and rules contained in the Landlord’s Health and Safety Manual;

  

	 	(ii)	 provide all clearances required by the Workplace Safety and Insurance Board or otherwise required at law;

 25 
  

 
  

	 	(iii)	 carry sufficient insurance, as required under the Building Code Act, the Occupational Health and
Safety Act, the Workplace Safety Act to the Landlord’s satisfaction; 

  

	 	(iv)	 be licensed by a governmental authority and carry such unexpired license at all times; and,

  

	 	(v)	 adhere to the terms of this Lease, including the Rules and Regulations. 

 

	4.4	 Repair Where Tenant at Fault. Notwithstanding any other provisions of this Lease but subject to the
release and waiver set forth in Section 7.9 of this Lease, if the Building or any part thereof is damaged or destroyed or requires repair, replacement or alteration as a result of the negligence or willful misconduct of the Tenant or any of
Tenant’s agents, employees, contractors or invitees, the cost of the resulting repairs shall be paid by the Tenant to the Landlord. 

  

	4.5	 Removal of Improvements and Fixtures. 

 

	(a)	 All Leasehold Improvements shall immediately upon their placement become part of the freehold and inure to the
Landlord’s property free and clear of all liens, encumbrances and security interests without compensation to the Tenant. Except as otherwise agreed by the Landlord in writing (which approval will not be unreasonably withheld and will not be
withheld if removal and/or replacement is required to comply with cGMP requirements), no Leasehold Improvements shall be removed from the Premises either during or at the expiration or sooner termination of the Term except that the Tenant may,
during or at the expiration of the Term, remove its Trade Fixtures. 

  

	(b)	 The Tenant agrees that all installations, Alterations and improvements made by or on behalf of Tenant shall be
made in accordance with all Applicable Laws and this Lease, including obtaining any consents required by this Lease and permits required by Applicable Laws and if Tenant fails to comply with such obligations, then the Tenant shall immediately upon
being directed by the Landlord to do so, remove, replace or otherwise amend same as directed by the Landlord so as to comply with municipal requirements. 

  

	(c)	 At the expiry of the Term or the earlier termination of the Term, Tenant will peacefully surrender the Premises
to Landlord in the condition which Tenant is required to keep the Premises under this Lease, reasonable wear and tear and loss or damage by casualty or condemnation excepted, and Tenant shall: (i) remove all of Tenant’s Trade Fixtures from
the Premises; (ii) remove any Leasehold Improvements that Tenant installs during the Term that are not a part of the Tenant’s Work that the Landlord advised Tenant in writing at the time Landlord approved the plans for such Leasehold
Improvements must be removed at the expiration or earlier termination of the Term; and (ii) repair all damage caused by the installation or removal of such Trade Fixtures. Tenant shall not be responsible for the removal of any Leasehold
Improvements upon the expiry of the Term or earlier termination of this Lease. 

 26 
  

 
  

	(d)	 If the Tenant does not remove its Trade Fixtures at the expiration or earlier termination of the Term as and to
the extent required by this Lease, the Trade Fixtures not removed shall, at the option of the Landlord, become its property (but not the risk and obligation therefor) and may be removed and disposed of by the Landlord in such manner as it deems
advisable. The Tenant shall maintain any reserves required for decommissioning obligations by the Canadian Nuclear Safety Commission or pursuant to the Tenant’s radiation safety licence issued by the Canadian Nuclear Safety Commission. This
covenant shall survive the expiration or earlier termination of this Lease. 

  

	4.6	 Liens. The Tenant shall promptly pay its contractors and suppliers for all materials supplied and work
done at its request in respect of Tenant’s work to the Premises. If a lien is registered or filed in respect of materials supplied or work done at the Tenant’s request, the Tenant shall discharge it at its expense forthwith; and if Tenant
fails to do so within twenty (20) days following notice from Landlord of any such lien, the Landlord may at its option, but shall not be obligated to discharge same by paying the amount claimed to be due into court together with any additional
amount required at law or by the court. The amount so paid and all expenses of the Landlord, and any solicitor’s fees (on a full indemnity basis) incurred by the Landlord, shall be paid by the Tenant to the Landlord within 10 Business Days
after demand. The costs of so doing may be collected by the Landlord as Additional Rent. 

  

	4.7	 Notice By Tenant. The Tenant shall notify the Landlord forthwith of any accident, defect, damage or
deficiency in any part of the Premises which comes to the attention of the Tenant, its employees or contractors notwithstanding that the Landlord may have no obligation in respect thereof. 

 

	4.8	 Intentionally deleted. 

 

	4.9	 Common Areas. The Landlord hereby grants Tenant a non-exclusive
licence over the Common Areas identified in Schedule “C” hereto. The Tenant shall not obstruct or encumber the Common Areas with any waste or property and shall not affix any fixtures, property or signs whatsoever on any portion of the
Common Areas without the express written consent of the Landlord. Where the Tenant requests additional services from the Landlord other than those obligations of the Landlord set out herein or the services to be provided free of charge pursuant to
this Lease or the Services Agreement, the Tenant shall be responsible for the Landlord’s costs of providing those services. The Landlord shall not be entitled to charge the Tenant for any operating costs, including those attributed by the
Landlord to the Common Areas, except as expressly provided to the contrary herein. 

 ARTICLE 5 –
LANDLORD’S WORK, TENANT’S WORK AND FIXTURING PERIOD 
  

	5.1	 Landlord’s Work. Notwithstanding Section 4.1 above, the Landlord shall
coordinate, install and complete the Landlord’s Work as outlined in Schedule “G” to this Lease at its sole cost and expense. For clarity, the Landlord shall be solely responsible for any cost increases in the Landlord’s Work
except solely for those expressly provided to be the Tenant’s obligation in Schedule “K” to this Lease and except to the extent such increases are being compensated via the Excess Facility Cost Payment by the Tenant. Landlord shall be
responsible for costs of coordinating Landlord’s Work on the Premises. The Landlord shall use commercially reasonable efforts to (i) achieve Substantial Performance of the Landlord’s Work with all Preconditions satisfied,
(ii) complete all of Landlord’s obligations pursuant to the Turnover Packages and (iii) complete all punch-list items (collectively, the “Turnover Condition”) by the Anticipated Premises Delivery Date and shall work
diligently to achieve the Turnover Condition as soon as possible thereafter if the Turnover Condition is not achieved by the Anticipated Premises Delivery Date. 

 27 
  

 
  

 The Landlord shall complete the Landlord’s Work in a good and workmanlike manner in
accordance with all Applicable Laws and prior to the Tenant taking possession of the Premises. Notwithstanding the foregoing, the Landlord agrees to make a good faith effort to accommodate any reasonable request from the Tenant to engage service
providers with domain expertise relating to the cGMP design, construction and commissioning of a radiopharmaceutical manufacturing facility. All other work required for the Premises including those items enumerated in 5.2 below as Tenant’s
Work, may be provided and if provided same will be installed by the Tenant at the Tenant’s sole expense. 
 The Landlord shall, as soon
as reasonably possible following execution of this Lease, work with the Tenant to identify the systems and sub-systems serving the Premises that need to be adequately commissioned and confirm if the
commissioning of the system or sub-system is the responsibility of the Landlord pursuant to the Landlord’s Work or Tenant pursuant to the Tenant’s Work. The Landlord will commission the base building
fixtures attached to the Premises, such as fume hoods and the Tenant shall commission all its own equipment. Landlord’s installations shall be commissioned and qualified with oversight from Tenant or its agent and be compliant with health and
safety regulations and Tenant’s installations or equipment shall be commissioned and qlaified with oversight from Tenant’s agent and be compliant with health and safety regulations. Landlord shall provide access to version controlled
documentation by the Tenant upon request for health inspections and readiness activities. The Landlord will then create Turnover Packages for the systems and sub-systems to adequately commission the system or sub-system to a set of criteria that is agreed upon with the Tenant and consistent with cGMP requirements to ensure they perform according to their intended design and specifications (the “Turnover
Packages”). The Turnover Packages will contain all necessary testing protocols, check sheets and walk- through check lists that verify each system’s performance. The Tenant and Landlord shall use commercially reasonable efforts to
review, agree upon and finalize the Turnover Packages. Both parties shall carry out their obligations pursuant to the Turnover Packages in a phased approach as the systems and sub-systems achieve a state of
completion, this can occur prior to Substantial Performance being achieved. The Landlord’s obligations include rectifying any Material Deficiencies and any deficiencies that are identified by Tenant or its representatives (punch list items)
during execution of the Turnover Packages or during walk-throughs. An agreed upon remediation plan will be developed and executed by the Landlord within a reasonable time commensurate with projects of this nature. Once Material Deficiencies and
punch-list items are adequately resolved to achieve Substantial Performance, a representative of the Landlord and Tenant will execute an agreement or acknowledgement confirming the Turnover Condition has been satisfied and the facility can be safely
occupied. 

 28 
  

 
  

 Notwithstanding anything to the contrary herein, if the Landlord does not provide the Tenant
with possession of the Premises in accordance with the Turnover Condition by the Anticipated Premises Delivery Date, subject to delay caused by Force Majeure or any Tenant Delay (as hereinafter defined), and subject to any extension or revised
Anticipated Premises Delivery Date pursuant to Schedule “K”, the Tenant shall be entitled to one (1) Rent-free day in respect of the Premises for each one (1) day thereafter that the Turnover Condition has not been satisfied. In
addition, if the Turnover Condition is not satisfied by the Anticipated Premises Delivery Date for any reason, including due to Force Majeure, all relevant dates, including the commencement of the Fixturing Period, Commencement Date, expiration of
the Term and all other relevant dates shall be delayed for the same number of days as satisfaction of the Turnover Condition is delayed from the Anticipated Premises Delivery Date. 

Subject to Force Majeure, any Tenant Delays and subject to any extension or revised Anticipated Premises Delivery Date pursuant to Schedule
“K”, if the Turnover Condition is not satisfied within six (6) months of the Anticipated Premises Delivery Date, the Tenant shall be permitted to terminate this Lease by notice to the Landlord. If for any reason, including due to
Force Majeure, the Turnover Condition is not satisfied within one (1) year of the Anticipated Premises Delivery Date, the Tenant shall be permitted to terminate this Lease by notice to the Landlord. 

For purposes hereof, “Tenant Delay(s)” shall mean and be limited to any actual delay (day for day) in the design, performance or
progress of Landlord’s Work beyond the Anticipated Premises Delivery Date to the extent not caused by Landlord or Landlord’s agents, employees or contractors and which cannot reasonably be mitigated by Landlord at no additional cost to
Landlord in good faith, using reasonable diligence, if and to the extent resulting from any of the following: 
 (i) any
changes or change order requested by Tenant to the Landlord’s Work (excluding, for the avoidance of doubt, any items requested by Tenant to correct any error, omission, noncompliance or deficiency in Landlord’s Work, all of which Landlord
shall correct at no additional cost to Tenant without the same constituting Tenant Delay(s)), unless the error, omission, non-compliance or deficiency was caused by the Tenant or found not to exist); or 

(ii) any other delays based upon acts or, where there is an obligation of Tenant to act under this Lease, omissions to the
extent the same actually delay the Landlord’s Work, and which are caused by Tenant, Tenant’s contractors, architects, engineers or anyone else engaged by Tenant in connection with the preparation of the Premises for Tenant’s
occupancy, including, without limitation, vendors or contractors furnishing communications, data processing or other service, equipment, or furniture. 

In calculating the duration of any Tenant Delay, such duration shall be based upon the actual number of days of delay to
Landlord’s Work beyond the Anticipated Premises Delivery Date if and to the extent attributable to the causes described above. In order to invoke Tenant Delay, Landlord must advise Tenant in writing of the alleged Tenant Delay reasonably
promptly after Landlord becomes aware thereof but in any event not later than 10 business days after Landlord becomes aware thereof. Landlord shall use commercially reasonable efforts to mitigate the impact of any Tenant Delay. 

 29 
  

 
  

 Landlord shall promptly notify Tenant in writing in the event a delay is
reasonably anticipated that could be a Tenant Delay, with reasonable particulars of the nature and cause of the delay. 
  

	5.2	 Tenant’s Work. 

 

	 	(a)	 The Tenant shall carry out its own fixturing at its own cost and expense as described in Schedule “H”
attached hereto (the “Tenant’s Work”), provided that Tenant has no obligation to complete any Tenant’s Work except as may be lawfully required to permit the Premises to be used by the Tenant as the Tenant may choose to use
them. Such Tenant’s Work shall be subject to the approval of the Landlord, acting reasonably and without undue delay or constraint and Landlord shall respond to any request for such approval within ten (10) Business Days after receipt of
Tenant’s request for approval or such Tenant’s Work will be deemed approved. Save and except for the cost of the Landlord’s Work, the Landlord shall not be obligated to pay any leasehold credit or payment to the Tenant for any
Leasehold Improvements. The Tenant agrees to finish the Premises to a standard commensurate with a cGMP facility for the Use. 

  

	 	(b)	 On completion of the Tenant’s Work, the Tenant shall forthwith furnish to the Landlord a statutory
declaration stating that: 

  

	 	(i)	 there are no construction liens outstanding against the Premises on account of the Tenant’s Work that have
not been bonded off or otherwise addressed to the reasonable approval of the Landlord; 

  

	 	(ii)	 that all accounts for work, services and materials have been paid in full with respect to all of the
Tenant’s Work, except for amounts that are being disputed in good faith; 

  

	 	(iii)	 the holdbacks required under the Construction Act have been made and released in accordance with that
legislation; 

  

	 	together	 with evidence in writing that: 

 

	 	(iv)	 all assessments under the Workplace Safety and Insurance Act have been paid; and, 

 

	 	(v)	 that the provisions of the Occupational Health and Safety Act have been adhered to during the completion
of the Tenant’s Work. 

  

	5.3	 Tenant’s Fixturing Period 

(a) The Tenant shall have a fixturing period to attend to certain improvements and Tenant’s Work as specified herein, starting on the
Commencement Date and ending on the date that is sixty (60) days thereafter (the “Fixturing Period”). Rent shall not be payable by the Tenant to the Landlord during the Fixturing Period but the Tenant and Landlord shall each
otherwise comply with their obligations hereunder and under the Services Agreement during the Fixturing Period. 

 30 
  

 
  

 (b) The Tenant may install Trade Fixtures of the type usual for its business which shall be
installed without damage to or impairment of the heating ventilation, air conditioning, electrical, plumbing, mechanical or telecommunication systems of the Premises or Building. 

(c) Subject to the terms of this Lease, the Tenant shall have the right during the Term, when not in default, to Alter such Trade Fixtures from
time to time in conformity with the provisions of Section 4.3 above. 
 (d) The Tenant may, without the Landlord’s prior written
consent but subject to Section 4.3 above, make changes, installations, alterations, additions or improvements to the Premises which do not affect the Building Systems or any structural elements. 

(e) The Landlord shall have the option at the end of the Term to require the Tenant to remove any and all Trade Fixtures of Tenant installed
during the Term and the Tenant shall do so at the Tenant’s expense forthwith upon notice from the Landlord, all in accordance with Section 4.5 above. 

(f) The Tenant agrees that any Alteration or Leasehold Improvement made to the Premises must comply with all municipal requirements (and for
this purpose, the Landlord’s consent shall not in any way be deemed a waiver of this requirement) and the Tenant agrees to obtain all required consents and permits in relation thereto. In the event any such installation, Alteration or
improvement shall be made without the necessary consent or permit, then the Tenant shall immediately upon being directed by the Landlord to do so, remove, replace or otherwise amend same as directed by the Landlord so as to comply with municipal
requirements. 
  

	5.4	 General. 

  

	 	(a)	 No items of the Tenant’s Work shall be commenced until the Tenant has secured approval thereof from every
governmental authority having jurisdiction, if required, and submitted proof of such approval to the Landlord, including the Tenant furnishing the Landlord with proof of having received a building permit for same. No Tenant’s Work shall
commence for which drawings and specifications are required until such drawings and specifications have been approved in advance, in writing by the Landlord or a written waiver of this requirement has been obtained from the Landlord, and all other
requirements of Section 4.3 hereof have been satisfied, such approval not to be unreasonably withheld, delayed or conditioned. 

  

	 	(b)	 The Tenant will not be permitted to enter the Premises for the purposes of performing the Tenant’s Work or
for the purpose of installing its fixtures and other equipment until the Tenant shall have deposited with the Landlord an insurance liability certificate in an amount not less than $2,000,000.00 per occurrence of such amount as the Landlord, acting
reasonably, may require from time to time with the Landlord added as an additional insured and with a cross liability clause; such insurance shall be on a comprehensive form and shall cover all hazards relating to any work performed by the Tenant or
its agents or independent contractors, as the case may be, on, in or at the Premises. 

 31 
  

 
  

	 	(c)	 In the event of any dispute between the parties under this Article 5 that is not resolved pursuant to
Section 10.8 of this Lease, then such dispute may be submitted by either party to arbitration in Hamilton for expedited proceedings or adjudication under the Construction Act. Judgment upon any award rendered in any arbitration or
adjudication held pursuant to this Section 5.4(c) may be entered in any court having jurisdiction, and in connection therewith, the arbitrators shall be bound by the provisions of this Lease, and shall not add to, subtract from or otherwise

provided that a Tenant representative is present to authorize access to all radioactive labs and other controlled areas of the Premises. Tenant shall use reasonable efforts to accommodate Landlord requirements for access and, except as may be

 ARTICLE 7 – INSURANCE AND INDEMNITY 

 

	7.1	 Tenant’s Insurance. 

 

	 	(a)	 The Tenant shall, throughout the Term, at its cost, take out and maintain: 

 

	 	(i)	 “All Risks” (including flood and earthquake) property insurance with reasonable deductibles taken by
a prudent tenant of premises similar to the Premises, naming the Landlord and any Mortgagee as additional insured parties, as their interests may appear and (except with respect to the Tenant’s chattels) incorporating the Mortgagee’s
standard mortgage clause. Such insurance shall cover: 

  

	 	A.	 all property owned by the Tenant or for which the Tenant is legally liable located on or in the Building or on
the Lands, including Leasehold Improvements in an amount not less than the full replacement cost, with such cost to be adjusted no less than annually; and 

  

	 	B.	 extra expense insurance in such amount as will reimburse the Tenant for loss attributable to all perils
referred to in this paragraph (a)(i) or resulting from prevention of access to the Premises. Such policy or policies, except with respect to extra expense insurance, shall, solely in respect of the Leasehold Improvements, provide that any loss shall
be adjusted and payable to the Landlord, with the proceeds to be held in trust to be used for repair and replacement of the property so insured; 

  

	 	(ii)	 comprehensive general liability insurance which includes: owner’s protective; personal injury; occurrence
property damage; and employers’ contingent contractual liability. Such policies shall contain inclusive limits of not less than $2,000,000.00; and 

  

	 	(iii)	 any other form of insurance or higher limits which the Tenant or the Landlord reasonably requires from time to
time in a form, in amounts and for risks against which a prudent tenant would insure. 

  

	 	(b)	 All policies referred to in subsection (a) above shall: 

 

	 	(i)	 be taken out with insurers acceptable to the Landlord, acting reasonably except that Landlord acknowledges and
agrees that Tenant’s existing insurance carrier is acceptable; 

  

	 	(ii)	 name the Landlord as an additional insured; 

 

	 	(iii)	 be in a form satisfactory from time to time to the Landlord, acting reasonably; 

 33 
  

 
  

	 	(iv)	 be non-contributing with, and shall apply only as primary and not as
excess to any other insurance available to the Landlord; 

  

	 	(v)	 not be invalidated as respects the interests of the Landlord and of any Mortgagee by reason of any breach or
violation of any warranties, representations, declarations or conditions; and 

  

	 	(vi)	 to the extent commercially available, contain an undertaking by the insurers to use reasonable efforts to
notify the Landlord no less than 30 days prior to any material change, cancellation or termination. 

 Certificates of
insurance shall be delivered to the Landlord annually, provided that the delivery to the Landlord of such certificates shall not limit or diminish the Tenant’s obligations contained in this subsection (b). 

 

	7.2	 Increase in Insurance Premiums. The Tenant shall not knowingly keep or use in the Premises any article
which may be prohibited by any fire insurance policy in force from time to time covering the Premises or the Building. If: (a) the conduct of business in the Premises; or (b) any acts or omissions of the Tenant in the Building or any part
thereof, cause or result in any increase in premiums for the insurance carried from time to time by the Landlord with respect to the Building the Tenant shall pay any such increase in premium. 

 

	7.3	 Cancellation of Insurance. If any insurance policy required of Tenant under this Lease shall be
cancelled or shall be threatened by the insurer to be cancelled or the coverage thereunder reduced by the insurer by reason of the unauthorized use of the Premises by the Tenant or any assignee or subtenant of the Tenant, or by anyone permitted by
the Tenant to be upon the Premises, and if the Tenant fails to promptly initiate to remedy such condition within 48 hours after notice thereof by the Landlord, the Landlord may, at its option, either: 

 

	 	(a)	 re-enter the Premises forthwith and thereupon the Landlord shall have
the same rights and remedies as are contained in Article 10; or 

  

	 	(b)	 enter upon the Premises and remedy the condition giving rise to such cancellation, threatened cancellation or
reduction, including removal of any offending article. The Tenant shall pay the cost of such action to the Landlord. The Landlord covenants that carrying on the Use will not cancel its insurance coverage. 

 

	7.4	 Intentionally Omitted. 

 

	7.5	 Landlord’s Insurance. The Landlord shall throughout the Term carry: 

 

	 	(a)	 “all-risks” property insurance on the Building in amounts
sufficient to fully cover, on a replacement cost basis without deduction for depreciation, the Building, and the machinery, boilers and equipment contained therein for servicing the Building and owned by the Landlord or the owners of the Building
(excluding any property with respect to which the Tenant is obliged to insure pursuant to Section 7.1); 

  

	 	(b)	 rental income insurance to cover all loss of rents for a period of 12 months; 

 34 
  

 
  

	 	(c)	 commercial general liability insurance on an occurrence basis, against claims for bodily injury, personal
injury and property damage with respect to the Landlord’s operations in the Building, with limits of $5,000,000.00 per occurrence and in the annual aggregate; 

 

	 	(d)	 rental loss insurance; and 

 

	 	(e)	 such other forms of insurance as the Landlord reasonably considers advisable. 

Such insurance shall be in such reasonable amounts and with such reasonable deductions as would be carried by a prudent landlord of a property
similar to the Building, having regard to size, age and location. The Landlord shall, upon request, provide a copy of an insurance certificate to the Tenant evidencing the placement of such insurance. Notwithstanding the Landlord’s covenant
contained in this Section 7.5 and notwithstanding any contribution by the Tenant to the cost of the Landlord’s insurance premiums, the Tenant agrees that no insurable interest is conferred upon the Tenant under any policies of insurance
carried by the Landlord and the Tenant has no right to receive any proceeds of any such insurance policies carried by the Landlord. 
  

	7.6	 Indemnification of the Landlord. Subject to Section 7.9, the Tenant indemnifies and holds harmless
the Landlord, its directors, officers, employees and agents (the “Landlord Released Persons”) from any and all claims, actions, causes of action, demands and costs for damage and injury, including death and other liabilities,
arising out of the Tenant’s use of or operations in the Premises, including the Land and Premises, or caused wholly or in part by the negligence of the Tenant, or any other Person for whom the Tenant is in law responsible, or due to or arising
out of any breach by the Tenant of this Lease, except where the damage or injury arises out of the negligence or wilful misconduct of the Landlord Released Persons or those for whom in law they are responsible. This indemnity shall survive the
expiry or termination of this Lease. 

  

	7.7	 Release of Landlord. The Tenant hereby releases the Landlord Released Persons from any and all claims,
actions, causes of action, damages, demands for damages and other liabilities, howsoever arising, and whether or not such loss or claim may have arisen out of the negligence of the Landlord Released Persons, to the extent that the Tenant is required
to obtain property insurance pursuant to this Lease or is otherwise insured for property loss; and the Tenant agrees to indemnify and hold harmless the Landlord Released Persons from any loss, cost, damage, expense, suit, action, and demand relating
to such claim or loss. 

  

	7.8	 Indemnity of Tenant. Subject to Section 7.7, the Landlord indemnifies and holds harmless the
Tenant, its directors, officers, employees, and agents from any and all claims, actions, causes of action, demands and costs for damage and injury, including death and other liabilities, arising out of the Landlord’s operations in the Lands, or
caused wholly or in part by the negligence of the Landlord, its agents, employees, contractors, or any Person for whom the Landlord is in law responsible, or due to or arising out of any breach by the Landlord of this Lease, except where the damage
or injury arises out of the negligence or willful misconduct of the Tenant, its directors, officers, employees, agents or those for whom in law they are responsible. This indemnity shall survive the expiry or termination of this Lease.

 35 
  

 
  

	7.9	 Release of Tenant. The Landlord hereby releases the Tenant, its directors, officers, employees, and
agents from any and all claims, actions, causes of action, damages, demands for damages and other liabilities, howsoever arising, and whether or not such loss or claim may have arisen out of the negligence of the Tenant, its directors, officers,
employees, and agents, to the extent that the Landlord is required to obtain property insurance pursuant to this Lease or is otherwise insured for property loss; and the Landlord agrees to indemnify and hold harmless the Tenant, its directors,
officers, employees, contractors and agents from any loss, cost, damage, expense, suit, action, and demand relating to such claim or loss. 

  

	7.10	 Indirect/Consequential Damages. Notwithstanding anything to the contrary in this Lease, the Landlord and
the Tenant each hereby releases the other and waives all claims against the other and those for whom the other is responsible in law with respect to indirect or consequential losses or damages, including loss of profits. Any costs incurred by Tenant
in connection with the performance of the Tenant’s Work and installation of Trade Fixtures which is not readily removable and reusable in another facility following any termination of this Lease due to Landlord’s failure to timely deliver
the Premises in the Delivery Condition shall constitute direct and not consequential damages of Tenant and such direct damages shall be recoverable against Landlord. Tenant acknowledges that the Landlord’s Work, to the extent the same
constitute leasehold improvements, shall remain with the Premises upon the expiration or earlier termination of the Term of this Lease. 

  

	7.11	 Environmental Indemnity 

 

	 	(a)	 Landlord’s Indemnity 

The Landlord acknowledges and will indemnify the Tenant for all costs, expenses, losses, damages, claims, orders, and liabilities (including
legal fees on a solicitor and client basis) in respect of (i) environmental conditions presently existing or discovered in the future in respect of the Premises which pre-existed the Term and the Tenant
shall not be responsible for such pre-existing conditions; and (ii) any breach of any Environmental Laws by Landlord or those for whom Landlord is in law responsible. 

 

	 	(b)	 Tenant’s Indemnity 

The Tenant shall indemnify the Landlord for any fines, fees or expenses incurred by it in relation to any default by the Tenant for securing
adequate permits, licenses or other required authorization to conduct or permit environmentally sensitive activities. The Tenant shall pay, satisfy, assume, discharge, observe, perform, fulfill, indemnify and save the Landlord, its officers,
directors and agents harmless against all liabilities, claims, demands, costs, orders, damages, and expenses of an environmental nature arising or accruing in any way from the Tenant’s use and occupation of the Premises. Without limiting the
foregoing, the Tenant agrees to abide by and indemnifies and saves the Landlord harmless from the Tenant’s failure to abide by the terms of any and all Certificates of Property Use, Certificate of Requirement or any other order, restriction or

 36 
  

 
  

 
requirement of the Ministry of Environment, registered on title to the Lands and/or provided to the Tenant by the Landlord. If the Landlord shall, without fault on its part, be made a party to
any litigation commenced by or against the Tenant or become subject to any fine, penalty, or order of a judicial, quasi-judicial or governmental authority, then the Tenant shall protect, indemnify and hold the Landlord harmless and shall pay all
expenses and reasonable legal fees incurred or paid by the Landlord in connection with such litigation, payment or action on a substantial indemnity basis. Tenant shall not be liable to remediate or to indemnify Landlord with respect to any matters
that Landlord is required to indemnify Tenant for under Section 7.11(a) above or any hazardous materials which migrate to the Premises, the Building or the Landlord through no fault of Tenant. 

The indemnities in these subsections 7.11(a) and (b) are absolute and unconditional and shall survive the termination of this Lease or any
Assignment thereof. 
  

	7.12	 Waiver of Subrogation. Each party agrees to have included in each of its insurance policies insuring the
Building and any other Landlord’s property therein in case of Landlord, and insuring Tenant’s property and leasehold improvements and Tenant’s improvements and betterments in the case of Tenant, against loss, damage or destruction by
fire or other casualty a waiver of the insurer’s right of subrogation against the other party during the Term or, if such waiver should be unobtainable or unenforceable, (i) an express agreement that such policy shall not be invalidated if
the assured waives the right of recovery against any party responsible for a casualty covered by the policy before the casualty or (ii) any other form of permission for the release of the other party. If such waiver, agreement or permission
shall not be, or shall cease to be, obtainable from either party’s then current insurance company, the insured party shall so notify the other party promptly after learning thereof, and shall use its best efforts to obtain the same from another
insurance company. Notwithstanding anything to the contrary contained herein, each party hereby releases the other party, with respect to any claim (including a claim for negligence) which it might otherwise have against the other party, for loss,
damage or destruction with respect to its property (including, without limitation, losses or damages to the Premises, the Building or any personal property of the other party) occurring during the Term to the extent to which it is, or is required to
be, insured under a policy or policies containing a waiver of subrogation or permission to release liability, as provided in the preceding subdivisions of this Section. Nothing contained in this Section shall be deemed to relieve either party of any
duty imposed elsewhere in this Lease to repair, restore or rebuild or to nullify any abatement of rents provided for elsewhere in this Lease. 

ARTICLE 8 – ASSIGNMENT AND TENANT’S SECURITY 
  

	8.1	 Assignments. The Tenant shall not permit or effect any Assignment without the prior written consent of
the Landlord, which consent may not be unreasonably withheld. Notwithstanding any statutory provision to the contrary, it shall not be considered unreasonable for the Landlord to take into account in deciding whether to grant or withhold its consent
whether, in the Landlord’s opinion, the financial background, business history and proposed use of the proposed Assignee (if different from the Tenant) is satisfactory. Consent by the Landlord to any Assignment, if granted, shall not constitute
a waiver of the necessity for such consent to any subsequent Assignment. 

 37 
  

 
  

	8.2	 Landlord’s Consent. If the Tenant intends to effect an Assignment, the Tenant shall give at least
30 days prior written notice to the Landlord specifying the identity of the proposed Assignee and shall provide such financial, business or other information in the Tenant’s possession or control relating to the Assignee and its principals as
the Landlord requires, together with copies of any documents which record the particulars of the proposed Assignment. 

  

	8.3	 Conditions of Assignment 

 

	 	(a)	 If there is an Assignment consented to by Landlord, the Landlord may, after an event of default of Tenant,
collect Rent from the Assignee and apply the net amount collected to the Rent required to be paid pursuant to this Lease but no acceptance by the Landlord of any payments by an Assignee shall be deemed a waiver of this covenant or any acceptance of
the Assignee as tenant or a release from the Tenant from the further performance by the Tenant of its obligations under this Lease. Any consent by the Landlord shall be subject to the Tenant and Assignee executing an agreement with the Landlord
agreeing that the Assignee will be bound by all of the terms of this Lease as if such Assignee had originally executed this Lease as tenant. 

  

	8.4	 No Advertising. The Tenant shall not advertise or permit to be advertised that the Premises are
available for Assignment. 

  

	8.5	 Assignment by the Landlord. The Landlord shall have the unrestricted right to sell, lease, convey or
otherwise dispose of the Premises or any part thereof and this Lease, including the right to grant, pledge or register a Mortgage against the Lands, the Premises, Common Areas or this Lease. To the extent that the purchaser or assignee from the
Landlord assumes the obligations of the Landlord under this Lease, the Landlord shall thereupon and without further agreement be released of all liability under this Lease assumed by such purchaser or assignee. 

 

	8.6	 Tenant’s Change of Ownership. If the Tenant is a corporation or other entity, the transfer or
issuance of shares in the capital stock, or the transfer, issuance or division of shares of the corporation sufficient to transfer direct voting control of the corporation shall not be deemed to be an Assignment within the meaning of this Lease but
shall require compliance with s. 2.5(c)(v) herein. 

  

	8.7	 Change of Control. When at any time more than 50% of the voting shares of the corporation that is the
Tenant, including any shares which are voting shares only upon the occurrence of a contingency where such contingency has occurred and is continuing, are assigned, gifted, exchanged or distributed, the Tenant shall give written notice of the change
in control to the Landlord within thirty (30) days of that event. 

 38 
  

 
  

	8.8	 Permitted Assignments. Notwithstanding anything to the contrary in this Article 8, the Tenant shall be
entitled, without the consent of the Landlord (but upon not less than ten (10) days prior written notice to Landlord), to assign all or any part of the Lease and/or the Premises to: 

 

	 	(a)	 a holding body corporate, subsidiary body corporate or affiliated body corporate (as all these terms are
defined pursuant to the Business Corporations Act (Ontario) as amended) of the Tenant; 

  

	 	(b)	 a corporation resulting from merger, amalgamation or other corporate reorganization of the Tenant; or

  

	 	(c)	 any person purchasing all or substantially all of the Tenant’s shares or Tenant’s assets in Canada
pursuant to an asset sale transaction. 

 In addition, an Assignment shall not include the transfer of shares of the Tenant
or a transfer of the shares of any parent, affiliate or subsidiary of the Tenant, it being acknowledged that such share transactions do not require the consent of the Landlord in relation to this Lease. In the event (and only in the event) of a
permitted Assignment pursuant to Section 8.8(c), the current Tenant shall be released from all obligations in this Lease. 
  

	8.9	 Tenant’s Security. 

 

	(a)	 The Tenant may, after the Commencement Date, register a Leasehold Mortgage charging its leasehold interest in
the Premises, this Lease and the Services Agreement on account of financing its improvements in and to the Premises with the prior written consent of Gore, FLIT, FLWR or Landlord, which consent may contain conditions or restrictions, including,

	 	(ii)	 the Leasehold Mortgage includes the Leasehold Mortgagee’s acknowledgment and agreement that:

  

	 	A.	 only the Tenant’s interest in the Premises, the Lease and the Services Agreement is mortgaged or
encumbered under such Leasehold Mortgage; 

  

	 	B.	 no foreclosure or sale will be made except of the Tenant’s leasehold interest in the Premises;

  

	 	C.	 the Landlord owes no obligations to the Leasehold Mortgagee under the Leasehold Mortgage; and

  

	 	D.	 the Landlord is not in any way responsible for any of the Tenant’s obligations under the Leasehold
Mortgage; 

  

	 	(iii)	 the Leasehold Mortgage shall provide that it is expressly subject and subordinate to the Landlord rights under
this Lease, the Services Agreement and in the Premises, in accordance with section 11.2 below and subject to the terms of the Multi-Party Agreement as defined below; 

 39

at the time the Leasehold Mortgage is given, extended, modified, renewed or replaced, as the case may be; 

  

	 	(v)	 the Leasehold Mortgage provides that it is not assignable by the Tenant; 

 

	 	(vi)	 the Tenant shall be responsible for all reasonable, out-of-pocket costs and expenses (including, without limitation, the Landlord’s legal fees) incurred by the Landlord in connection with the Tenant entering into, extending, modifying, renewing or
replacing the Leasehold Mortgage and the Landlord negotiating the terms of and entering into the Multi-Party Agreement, and same shall be paid to the Landlord by the Tenant on demand, and, in any event, prior to the Sublandlord executing the
Multi-Party Agreement; 

  

	 	(vii)	 any such security given by the Tenant must be postponed in favour of those instruments or interests identified
by the Landlord as having priority, including any Mortgage given by the Landlord, FLWR, FLIT or Gore and any site plan or development agreement with the City of Hamilton and any prior ranking lease to which Landlord, FLWR, FLT or Gore is a party;

  

	 	(viii)	 the Leasehold Mortgagee has, contemporaneously with the entering into of the Leasehold Mortgage, entered into
an agreement (the “Multi-Party Agreement”) with Gore, FLIT, FLWR and the Landlord, in a form acceptable to all parties, acting reasonably, to the effect that: 

 

	 	A.	 the Leasehold Mortgagee may enforce its Leasehold Mortgage and acquire title to the Tenant’s leasehold
estate in any lawful manner; 

  

	 	B.	 if and when the Leasehold Mortgagee becomes a mortgagee in possession or the owner of the Tenant’s
interest in this Lease; it will: 

  

	 	I.	 during such time as it remains a mortgagee in possession or the owner of the Tenant’s interest in this
Lease and Services Agreement, be bound by and perform all of the Tenant’s covenants as if it had been the original Tenant under this Lease and the Services Agreement; 

 

	 	II.	 within 10 Business Days of the date that it goes into possession, remedy all monetary defaults of the Tenant
under this Lease and the Services Agreement; 

 40 
  

 
  

	 	III.	 upon going into possession, use its commercially reasonable efforts to diligently and continuously proceed to
remedy all non-monetary defaults of the Tenant under this Lease and the Services Agreement; and 

  

	 	IV.	 provided the Leasehold Mortgagee complies with (I)-(III) above, the Leasehold Mortgagee shall be permitted to
remain in possession of the Premises if it is not in default of the terms of this Lease or the Services Agreement. 

  

	 	C.	 the Leasehold Mortgagee will not assign the Tenant’s rights under this Lease or the Services Agreement
without complying with Article 8. Upon such an assignment, the Leasehold Mortgagee shall be released by the Landlord from all future obligations under this Lease and the Services Agreement, but shall not be released from any liability in respect of
obligations under this Lease or the Services Agreement arising prior to the date of the assignment if the Leasehold Mortgagee has become responsible for same; 

 

	 	D.	 the Landlord shall, concurrently with delivery of such notice to the Tenant, give the Leasehold Mortgagee
copies of all notices of default which the Landlord gives to the Tenant and shall allow the Leasehold Mortgagee to rectify the default which is the subject-matter of such notice within the same period of time as the Tenant has available to it to
rectify such default; and 

  

	 	E.	 the Leasehold Mortgagee shall be entitled to enforce the provisions of this Section 8.9 against the
Landlord. 

  

	(b)	 Any Leasehold Mortgage, if allowed by the Landlord or permitted by this Section 8.9, shall only be
registered, if at all, on or against the leasehold parcel for the Building.

Mortgage registered on title to the Lands granted by Gore, FLIT or FLWR and in accordance with section 11.2 below. 

 41 
  

 
  

 ARTICLE 9– DAMAGE, DESTRUCTION AND EXPROPRIATION 

 

	9.1	 No Abatement. If the Premises or the Building are damaged or destroyed in whole or part by fire or any
other occurrence, this Lease shall continue in full force and effect and there shall be no abatement of Rent except as provided in this Article 9. 

  

	9.2	 Damage to Premises. If the Building, including the Premises, is at any time destroyed or damaged as a
result of fire or any other casualty, then the following provisions shall apply: 

  

	 	(a)	 if one-half or less of the area of the Premises is rendered
untenantable, the Landlord shall diligently repair it (excluding any Leasehold Improvements but including Landlord’s Work) and Gross Rent and Additional Rent shall abate proportionately to the portion of the Building rendered untenantable from
the date of destruction or damage until the Landlord’s repairs have been completed; 

  

	 	(b)	 if more than one-half of the area of the Premises is rendered
untenantable, the Landlord shall diligently repair it (excluding the Leasehold Improvements) and Gross Rent and Additional Rent shall abate entirely from the date of destruction or damage until the Landlord’s repairs have been completed;

  

	 	(c)	 if the Premises is not rendered untenantable in whole or in part, the Landlord shall diligently perform such
repairs to it (excluding the Leasehold Improvements), but in such circumstances Gross Rent and Additional Rent shall not terminate or abate; 

  

	 	(d)	 upon being notified by the Landlord that the Landlord’s repairs have been substantially completed, the
Tenant shall diligently perform all repairs to the Premises which are the Tenant’s responsibility under Sections 4.1 and 4.2 (including the installation of Leasehold Improvements) and all other work required to fully restore the Premises for
use in the Tenant’s business, in every case at the Tenant’s cost and without any contribution to such cost by the Landlord, whether or not the Landlord has at any time made any contribution to the cost of, supply, installation or
construction of Leasehold Improvements or actually supplied, installed or constructed such Leasehold Improvements; 

  

	 	(e)	 nothing in this Section 9.2 requires the Landlord to rebuild the Building to the condition which existed
before any such damage or destruction so long as the Building, as rebuilt (prior to the Tenant’s Work under paragraph (d) above), will, subject to compliance with Applicable Laws be constructed in accordance with design specifications
included in the Landlord’s Work or as otherwise agreed upon between the Landlord and the Tenant, having regard to the age of the Building at such time, and subject to the limitations on the Landlord’s obligations to restore as set out in
this Section 9.2 and will include the Landlord’s Work; however, the Landlord’s obligation to rebuild the Building will, in the Landlord’s discretion, not apply if the damage or destruction occurs at any time during the last 18
months of the Term; and 

 42 
  

 
  

	 	(f)	 provided that the Landlord has complied with its insurance obligations under Section 7.5 hereof, nothing
in this Section 9.2 shall require the Landlord to undertake any repairs or replacements having a cost in excess of the insurance proceeds actually received by the Landlord with respect to such damage or destruction and in the event such
insurance proceeds are less than the cost of such repair or replacement, the Landlord’s obligations shall be governed in the first instance by the provisions of Section 9.2. 

 

	9.3	 Right of Termination. Notwithstanding Section 9.2, if the damage or destruction which has occurred
in or to the Building is such that in the reasonable opinion of the Architect the Premises cannot be rebuilt or made fit for the purposes of the Tenant within nine (9) months following the date that restoration of the Premises would commence,
either the Landlord or the Tenant may, at its option, terminate this Lease on notice to the other party given within 15 days after the determination of the Architect. If any such notice of termination is given, Rent shall be apportioned and paid to
the date of such damage or destruction and the Tenant shall immediately deliver vacant possession of the Premises in accordance with the terms of this Lease. 

  

	9.4	 Destruction of Building. 

 

	 	(a)	 Notwithstanding any other provision of this Lease, if all or any portion of the Building shall be damaged or
destroyed, to the extent that the estimated costs of repairing, restoring or rebuilding it shall, by the Architect’s estimate, exceed by 10% or more the proceeds of insurance available to the Landlord for the purpose of repair, restoration or
rebuilding, then the Landlord may, by notice to the Tenant given within 30 days of such damage or destruction, terminate this Lease, in which event neither the Landlord nor Tenant shall be bound to repair and the Tenant shall surrender the Premises
to the Landlord within 30 days after delivery of its notice of termination and Rent shall be apportioned and paid to the date on which the Tenant delivers vacant possession of the Premises, subject to any abatement to which the Tenant may be
entitled pursuant to Section 9.2. 

  

	 	(b)	 If the Landlord is entitled to, but does not elect to terminate this Lease, the Landlord shall, following such
damage or destruction, diligently repair if necessary that part of the Building damaged or destroyed (exclusive of any responsibilities of the Tenant with respect to such repair). If the Landlord elects to repair the Building, the Landlord may do so
in accordance with plans and specifications other than those used in the original construction of the Building provided it shall carry out all of the Landlord’s Work; however, any such construction shall be suitable for the Tenant’s use,
shall comprise an area not less than the original construction and shall be of a quality equal to but not less than the original construction. 

  

	9.5	 Architect’s Certificate. The certificate of the Architect shall bind the parties as to:

  

	 	(a)	 whether or not the Premises are rendered untenantable and the percentage of the area of the Premises rendered
untenantable; 

  

	 	(b)	 the date upon which either the Landlord’s or Tenant’s work of reconstruction or repair is completed
or substantially completed and the date when the Premises are rendered tenantable; and, 

 43 
  

 
  

	 	(c)	 the state of completion of any work of the Landlord or Tenant. 

 

	9.6	 Expropriation. If the Building or any part thereof shall be expropriated or if any material portion of
the Lands shall be expropriated by any competent authority, then: 

  

	 	(a)	 the Landlord and the Tenant shall cooperate with each other so that the Tenant may receive such award to which
it is entitled in law and so that the Landlord may receive the maximum award to which it may be entitled in law, each for all compensation arising from such expropriation including, without limitation, all compensation for the value of the
Tenant’s leasehold interest in the Premises; and 

  

	 	(b)	 the Landlord shall have the option, to be exercised by written notice to the Tenant, to terminate this Lease
effective on the date the expropriating authority takes possession of the whole or any portion of the Building. 

ARTICLE 10 – DEFAULT 
  

	10.1	 Default and Remedies. If and whenever: 

 

	 	(a)	 any Rent is in arrears and is not paid within 10 days after written demand by the Landlord specifying such
default; 

  

	 	(b)	 the Tenant has breached any of its obligations in this Lease (other than the payment of Rent) or the Services
Agreement and the Tenant fails to remedy such breach within 30 days (or such shorter period if such shorter cure period is explicitly provided in this Lease) or if such breach cannot reasonably be remedied within 30 days or such shorter period, the
Tenant fails to commence to remedy and thereafter proceed diligently to remedy such breach, in each case after notice in writing from the Landlord; 

  

	 	(c)	 the Tenant becomes bankrupt or insolvent or takes the benefit of any statute for bankrupt or insolvent debtors
or makes any proposal, assignment or arrangement with its creditors, or any steps are taken or proceedings commenced by any Person for the dissolution, winding-up or other termination of the Tenant’s
existence or the liquidation of its assets; 

  

	 	(d)	 a trustee, receiver, receiver/manager or like Person is appointed with respect to the business or assets of the
Tenant; 

  

	 	(e)	 this Lease or any of the Tenant’s assets are taken under a writ of execution; 

 

	 	(f)	 any of the Landlord’s policies of insurance with respect to the Building or any part thereof are cancelled
or are at risk of being cancelled solely and directly as a result of the Tenant’s use or occupancy of the Premises (as opposed to general use for the Use permitted hereunder in the normal course) and Tenant does not cease or adjust such manner
of use within two (2) Business Days after receiving written notice from Landlord; 

 44 
  

 
  

	 	(g)	 the Tenant adopts and/or uses any intellectual property of the Landlord, McMaster University or McMaster
Innovation Park, without first entering into an Intellectual Property License Agreement with the Landlord and such default is not cured within two (2) Business Days after Tenant receiving notice of such default from Landlord;

  

	 	(h)	 the Tenant makes an Assignment or gives security to a third party not in compliance with this Lease;

 then without prejudice to any other rights which it has pursuant to this Lease or at law, the Landlord shall have the
following rights and remedies, which are cumulative and not alternative: 
  

	 	(i)	 to terminate this Lease by notice to the Tenant; 

 

	 	(ii)	 to enter the Premises as agent of the Tenant and to re-let the Premises
for whatever term, and on such terms as the Landlord in its discretion may determine and to receive the Rent therefore and as agent of the Tenant to take possession of any property of the Tenant on the Premises, to store such property at the expense
and risk of the Tenant or to sell or otherwise dispose of such property in such manner as the Landlord may see fit without notice to the Tenant; 

  

	 	(iii)	 to remedy or attempt to remedy any default of the Tenant under this Lease for the account of the Tenant and to
enter upon the Premises for such purposes. No notice of the Landlord’s intention to perform such covenants need be given to the Tenant unless expressly required by this Lease. The Landlord shall not be liable to the Tenant for any loss or
damage caused by acts of the Landlord in remedying or attempting to remedy such default and the Tenant shall pay to the Landlord all expenses incurred by the Landlord in connection with remedying or attempting to remedy such default;

  

	 	(iv)	 to recover from the Tenant all damages and expenses incurred by the Landlord as a result of any breach by the
Tenant including, if the Landlord terminates this Lease, any deficiency between those amounts which would have been payable by the Tenant for the portion of the Term following such termination and the net amounts actually received by the Landlord
during such period of time with respect to the Premises; and 

  

	 	(v)	 in lieu of Landlord’s rights to recover under Section 10.1(h)(iv) above, to recover from the Tenant
the full amount of the current month’s Rent together with the next 3 months’ installments of Rent; all of which shall accrue on a day-to-day basis and shall
immediately become due and payable as accelerated Rent. 

  

	10.2	 Distress. Notwithstanding any provision of this Lease or any provision of applicable legislation, none
of the goods of the Tenant on the Premises at any time during the Term shall be exempt from levy by distress for Rent in arrears, and the Tenant waives any such exemption. If the Landlord makes any claim against the goods and chattels of the Tenant

 45 
  

 
  

	 	
by way of distress, this provision may be pleaded as an estoppel against the Tenant in any action brought to test the right of the Landlord to levy such distress. Notwithstanding the foregoing,
the Landlord covenants and agrees with the Tenant to enter into an agreement with the Tenant’s lenders, from time to time, whereby the Landlord subordinates its rights of distraint in the Tenant’s Trade Fixtures, Leasehold Improvements,
equipment and inventory to those of the lender, which agreement shall be in form and content satisfactory to the Tenant’s lender. 

  

	 	 Notwithstanding the foregoing, the Landlord shall not be entitled to effect a distress against computer
software, computer discs, computer programs and tapes, client lists, client and customer property (including, without limitation, computer hardware and software), personnel or employee information, and any data in the hard drives of any computers on
the Premises, nor against the books, records, accounts, files, correspondences and documents found upon the Premises or any part thereof including, without limitation, all proprietary and confidential information and the Landlord hereby waives any
right, statutory or otherwise, to levy a distress in that regard. 

  

	10.3	 Costs. The Tenant shall pay to the Landlord on demand all costs incurred by the Landlord, including
reasonable lawyers’ fees, on a substantial indemnity basis (or full indemnity basis, if specifically stated herein), incurred by the Landlord in enforcing any of the obligations of the Tenant under this Lease. 

 

	10.4	 Allocation of Payments. The Landlord may at its option apply sums received from the Tenant against any
amounts due and payable by the Tenant under this Lease in such manner as the Landlord sees fit. 

  

	10.5	 Survival of Obligations. All obligations of the Tenant under this Lease which remain unfulfilled at the
determination of this Lease and the Landlord’s rights in respect of any failure by the Tenant to perform any of its obligations under this Lease shall survive and remain in full force and effect notwithstanding the expiration or earlier
termination of the Term. 

  

	10.6	 Additional Rent Deemed Rent. All Additional Rent, if any, shall be deemed to be Rent and the Landlord
shall have all rights against the Tenant for default in the payment of Additional Rent as for default in the payment of Gross Rent, except as otherwise herein provided. 

 

	10.7	 Landlord’s Right To Perform. In addition to all other remedies the Landlord may have by this Lease,
at law or in equity, if the Tenant does not perform any of its obligations hereunder, the Landlord may, at its option, but without any obligation, perform any of such obligations of the Tenant, after 30 days’ notice to the Tenant or in the
event of an emergency, without notice, and in such event, the cost of performing any of such obligations, plus an administrative charge of 10% of such cost, shall be payable by the Tenant to the Landlord forthwith on demand, and collectable as
Additional Rent. 

 46 
  

 
  

	10.8	 Dispute Resolution. Notwithstanding any remedy available to the Landlord under Section 10.1 prior
to exercising any remedies provided for herein, the parties shall use commercially reasonable attempts to resolve the dispute or breach as follows: 

  

	 	(a)	 The Head of Operations of the Tenant and the AVP (Administration) and CFO of the Landlord shall discuss the
nature of the dispute and attempt, within 10 days of notification of the dispute, to resolve same to the mutual satisfaction of the parties; 

  

	 	(b)	 If the representatives of the parties under Section 10.8 are not able to resolve the dispute or breach
within the aforementioned 10 days, the CEO of the Tenant and the Vice-President (Administration) of the Landlord shall meet and attempt to resolve the dispute within 10 days; 

 

	 	(c)	 If the dispute or breach is not resolved under Section 10.8(a) and (b), then the parties may consider
mediating the dispute with a third party neutral or arbitration of the dispute (any of which is without obligation on either party), or exercise any remedies available in this Lease or at law. 

ARTICLE 11 – STATUS STATEMENT, ATTORNMENT AND SUBORDINATION 

 

	11.1	 Status Statement. Within 10 days after written request by the Landlord, the Tenant shall deliver to the
Landlord, in a form supplied by the Landlord and reasonably satisfactory to the Tenant, a certificate as to the status of this Lease, the amount of Rent then being paid and the dates to which it has been paid and any other factual matters pertaining
to this Lease as to which the Landlord shall request in such certificate. 

  

	11.2	 Subordination and Non-Disturbance Agreement.

  

	(a)	 Subject to the terms of this Section 11.2, this Lease and all rights of the Tenant shall be subject and
subordinate to the lien of any and all Mortgages from time to time in existence against the Lands or any part thereof, whether freehold or leasehold, provided, however, Landlord shall, upon receipt of a request from Tenant, use reasonable efforts to
obtain a commercially reasonable non-disturbance agreement from any existing or potential mortgagees providing that so long Tenant is not in default in any of its obligations hereunder the party to which it is
subordinating its interest shall not disturb the Tenant’s possession of the Premises during the Term. On or within 60 days following execution and delivery of this Lease, Landlord shall obtain and deliver to Tenant a consent, non-disturbance and recognition agreements (“Master Lease NDAs”) from the lessors under all of the Master Leases in effect as of the date of this Lease in the form attached hereto as Schedule
“L”. The subordination of this Lease to any future ground leases or other overleases shall be conditioned upon Tenant’s receipt of a Master Lease NDA in substantially the form attached hereto as Schedule “L” from the
lessors. Landlord shall extend (or cause the extension of) all overleases for term or terms that enable the Term of this Lease (as it may be extended). 

 47 
  

 
  

	11.3	 Attornment. Subject to Section 11.2, the Tenant shall promptly attorn on request to any Mortgagee,
or to the registered owner of the Lands or the lessee under any Lease of all or substantially all of the Lands made by the Landlord or otherwise affecting the Lands or the purchaser on any foreclosure or sale under proceedings taken under any
Mortgage, and shall recognize such Mortgagee, owner, lessee or purchaser as the Landlord under this Lease. 

ARTICLE 12 – LANDLORD COVENANTS, REPRESENTATIONS AND WARRANTIES 

 

	12.1	 Quiet Enjoyment. The Landlord covenants that if the Tenant pays Rent and observes and performs all of
its obligations under this Lease within applicable notice and cure periods, the Tenant shall, subject to the provisions of this Lease, be entitled to peaceful and quiet enjoyment of the Premises for the Term without interruption or interference by
the Landlord or any Person claiming through the Landlord. 

  

	12.2	 General Covenants of Landlord. The Landlord hereby covenants to perform all of the covenants and
obligations hereunder and under the Services Agreement to be performed by the Landlord and to diligently enforce, at Tenant’s sole cost and expense, any of the obligations of the lessors under the Master Leases. The Landlord covenants to advise
the Tenant of any default it becomes aware of under any of the Master Leases and provide the Tenant with all notices it receives from any party to any of the Master Leases or any governmental authority with respect to the Premises or the
Tenant’s business therein. Landlord shall not voluntarily terminate or consent to any termination of any of the Master Leases or Services Agreement without Tenant’s consent, provided, however, Tenant’s consent will not be required if
the provisions of the Master Lease NDAs will preserve Tenant’s rights under this Lease to use and occupy the Premises and receive the services under the Services Agreement. 

 

	 	 Landlord indemnifies and holds harmless the Tenant from any and all losses, claims, actions, causes of action,
demands and costs for damage and injury, arising from any loss of Tenant’s rights to use and occupy the Premises arising out of (i) the expiration or termination of any of the Master Leases prior to the expiration of the Term of this Lease
(as the same may be extended), including as the result of the foreclosure of or other exercise of any rights under any Mortgages, except where such termination is due to the breach of the Tenant, its directors, officers, employees, agents or those
for whom in law they are responsible of its obligations under this Lease beyond applicable notice and cure periods, or (ii) any breach of Landlord’s representations, warranties and covenants set forth in Section 12.3 below. This
indemnity shall survive the expiry or termination of this Lease. 

  

	12.3	 Landlord Representations, Warranties and Covenants. The Landlord hereby represents, warrants and
covenants to the Tenant as follows: 

  

	 	(a)	 it will at all times keep the FLWR-Landlord Sublease in good standing and comply in full with all of its
obligations therein, including paying any rent due thereunder and will exercise any extension options thereunder necessary to accommodate the Term of this Lease; 

 48 
  

 
  

	 	(b)	 that it will not agree to any termination of the FLWR-Landlord Sublease or any amendments thereto or any of the
Master Leases that will adversely impact the Premises or the Tenant’s rights hereunder, without the consent of the Tenant, which may be withheld in the Tenant’s sole discretion; 

 

	 	(c)	 there are no requirements, nor to the best of the Landlord’s knowledge and belief are there any pending
requirements, of any governmental authority or department of any kind which may require any modifications to be done to the Building or Lands (upon completion of Landlord’s Work) in order to permit the Tenant to occupy the Premises for the Use;

  

	 	(d)	 there are no restrictions or provisions in any of the Master Leases that would prohibit or restrict Tenant from
carrying on the Use or exercising any of its rights herein or increase the costs to the Tenant to do so, except as may be set out herein or in the Services Agreement; 

 

	 	(e)	 there are no restrictions or provisions in any of the Master Leases or registered on title to the Lands
(including under the Land Use Restrictions) that would prohibit the Landlord from carrying out its obligations set forth herein and in the Services Agreement; 

 

	 	(f)	 the Landlord has full right and authority and has taken all necessary action to execute this Lease and to
fulfill its obligations herein and no consent or approval of any party is required for the Landlord to execute and deliver this Lease and perform its obligations hereunder; 

 

	 	(g)	 as of the date hereof, the Landlord and each party to any of the Master Leases has not received any notices of
violation, claims, disputes or litigation of any kind, pending or threatened, with respect to the Lands or the Premises that could inhibit or prevent the Landlord or Tenant from carrying out its obligations herein; 

 

	 	(h)	 Landlord shall enforce the obligations of FLWR under the FLWR-Landlord Sublease and any rights of Landlord
under any of the Master Leases to enforce the obligations of the landlords thereunder to comply with their respective obligations under the Master Leases to supply services and perform repairs, replacements or restoration to the Building if and to
the extent necessary to permit Tenant to continue its use and occupancy of the Premises for the Use (or following a casualty to resume occupancy); and 

  

	 	(i)	 no consents are required under any of the Master Leases to enter into this Lease or carry out the Use at the
Premises except as such consents may be set forth herein or in the Services Agreement. 

  

	 	(j)	 Landlord shall not amend or consent to the amendment of any of the Master Leases in a manner that will
adversely affect Tenant’s rights or increase Tenant’s obligations under this Lease, without Tenant’s prior written consent, not to be unreasonably withheld, conditioned or delayed. 

 49 
  

 
  

 ARTICLE 13– GENERAL PROVISIONS 

 

	13.1	 Intentionally deleted. 

 

	13.2	 Rules and Regulations. The Tenant shall comply with all Rules and Regulations, and reasonable amendments
to them, adopted by the Landlord from time to time, so long as such Rules and Regulations are not inconsistent with and do not contradict this Lease and provided that no amendments to the Rules and Regulations shall be binding on the Tenant until it
shall have received fifteen (15) days prior written notice thereof. Unless any amendment is required by law, proposed amendments to the Rules and Regulations by the Landlord shall only be effected or applicable to the Tenant provided the
Landlord first enters into consultations with the Tenant and such consultations shall last no longer than ten (10) Business Days after notice is delivered to the Tenant, unless extended by mutual agreement in writing. Notwithstanding anything
to the contrary herein, the Landlord and Tenant shall comply with the rules and regulations set forth in Schedule “C” to the Services Agreement.

Gross Rent payable during the last month of the Term, and otherwise upon the same terms as set out in this Lease, if applicable to a monthly tenancy. 

  

	13.5	 Waiver. If either the Landlord or Tenant excuses or condones any default by the other of any obligation
under this Lease, this shall not be a waiver of such obligation in respect of any continuing or subsequent default and no such waiver shall be implied. 

  

	13.6	 Registration. Neither the Tenant nor anyone claiming under the Tenant shall register this Lease or any
Assignment thereof on title to the Lands except that Landlord and Tenant shall execute and deliver a Notice of Lease in a registerable form reasonably acceptable to the Landlord and either party may record or register the same. If the Tenant or any
permitted assignor wishes to register a document evidencing this Lease, then the Landlord shall at the request and expense of the Tenant execute a notice of Lease for the purposes of registration in such form as reasonably required by the Tenant and
without disclosure of any financial terms which the Landlord does not desire to have disclosed. Such registration, if allowed by the Landlord, shall only be registered against the leasehold parcel for the Building.

breach of this Lease for its delay, failure or inability to meet any of its obligations hereunder (other than the obligation to pay money and compliance with the MIP Biosafety Program and Radiation Safety Program) caused by or arising from any cause
which is unavoidable or beyond the reasonable control of such Party, including war, warlike operations, terrorism, riot, civil commotion or insurrection, orders of government or other government action, fire, flood or any natural disaster, strikes,
lockouts, boycotts or other labour disputes, quarantines, epidemics or pandemics, protests, disturbances or any act of God, shortage of materials, delay in transportation, delay in delivery by vendors, suppliers, subcontractors or any other cause
which is beyond the reasonable control of the applicable party hereto or which frustrates the performance of this Lease.

provided to the contrary in this Lease, and no extension or variation of this Lease shall operate as a waiver of this provision. When calculating the period of time within which or following which any act is to be done or step taken pursuant to this
Lease, unless this Lease provides to the contrary, the date which is the reference date in calculating such period shall be excluded.
