 The Lessor hereby rents the premises described in Schedule A and

	 	2.2	 Area of the Leased Premises 

The area of the Leased Premises is stated in Schedule A. The Lessor may, at their entire discretion, have the Leased
Premises measured by an architect or surveyor within 90 days following the Commencement Date or at such later time as the Parties, acting reasonably, may agree to. The Lessor will promptly deliver a copy of the report prepared by the architect or
surveyor to the Lessee and the area as disclosed by the architect or surveyor’s report will thereafter, but with effect retroactive to the Commencement Date, be the final area of the Leased Premises, binding on all Parties, unless contested in
writing within ten (10) days of receipt of the said certificate. If any adjustments have to be made in respect of amounts paid or payable by the Lessee prior to delivery of any certificate referred to in this Section, they will be made by
(i) payment by the Lessee of any amount it owes to the Lessor, within 30 days after the Lessee receives its copy of the certificate or (ii) crediting any amounts which the Lessor owes to the Lessee against the payments by the Lessee next

	 	2.4	 Access to Common Facilities 

Rental by the Lessee of the Leased Premises entitles the Lessee to use the Common Facilities provided by the Lessor to all tenants in the
Building. 
  

	3	 TERMS OF LEASE 

 

	 	3.1	 Term 

The term of this Lease is for the period set forth in Schedule A (the “Initial Term”), subject
to early termination or renewal in accordance with the provisions of this Lease. 
  

	 	3.2	 Renewal 

  

	 	3.2.1	 Provided (i) this Lease is then in full force and effect, (ii) the Lessee is itself in occupancy and
carries on business in and from the entirety of the Leased Premises, and (iii) the Lessee is not in default in the performance of its obligations under this Lease, the Lessee shall have one (1) option to extend the Initial Term, for a
period of five (5) years (the “Extension Term”), commencing on the day immediately following the last day of the Initial Term, under the same terms and conditions as are contained in this Lease save and except that:

  

	a.	 the Lessee shall accept the Leased Premises “as is – where is” in their then state and
condition; 

  

	b.	 the Rent shall be the then prevailing rental rate which the Lessor could reasonably obtain for the Leased
Premises from a willing tenant dealing at arm’s-length with the 

  
 3 

	 	
Lessor in the market as of the date on which the Lessee exercises the option to extend, having regard to all relevant circumstances, including, without limitation, the length of the Extension
Term, the size and location of the Leased Premises, the terms and provisions of this Lease for the Extension Term, the age, use and condition of the Leased Premises, the rentals being obtained for comparable space in comparable locations in the
municipality where the Leased Premises are situated; and 

  

	c.	 there will be no further options to extend the Term. 

 

	 	3.2.2	 The option to extend contained in this Section may only be exercised by Lessee giving Lessor written notice to
such effect no less than twelve (12) months prior to the commencement of the Extension Term. In the event the Lessee fails to exercise this option to extend in the manner and before the deadline mentioned above, such option to extend will be
irrevocably deemed to have been waived and to have become null and void and never to have existed. In the event that the Lessee exercises this option to extend in the manner and before the deadline mentioned above, the Parties will endeavour to
negotiate in good faith and to execute a written agreement as to the Rent payable for the Extension Term as soon as reasonably possible after the exercise by the Lessee of the option to extend. 

 

	 	3.2.3	 Within thirty (30) days from the exercise by the Lessee of the option to extend, the Lessor shall provide
the Lessee its proposed Rent for the Leased Premises for the Extension Term. 

  

	 	3.2.4	 In the event that the Parties fail for any reason to agree in writing upon the Rent to apply for the Extension
Term at the latest four (4) months after the exercise by the Lessee of the option to extend, then such dispute shall be submitted to arbitration before a single arbitrator selected by the Parties within fifteen (15) days following the
expiry of this 4-month period, failing which either may ask the Superior Court of Québec, sitting in the judicial district of Montreal, to appoint such arbitrator. The Parties shall not be bound during
such proceeding by the Rent proposed by each of them respectively. The decision of the arbitrator as to the Rent during the Extension Term shall be final and binding on the Parties with no right of appeal. The arbitrator shall be an independent
appraiser duly qualified in the evaluation of commercial real estate in Montreal and the determination of rentals applicable thereto, with at least ten (10) years of experience with the industrial real estate sector and shall be a qualified
member of the Ordre des évaluateurs agréés du Québec. The costs and expenses of the arbitrator and of the arbitration proceedings shall be borne equally by
the Lessor and the Lessee but each Party shall bear the costs of its own legal counsel and any professional advisers, appraisers or evaluators employed by it. If the decision of the arbitrator is not rendered prior to the commencement of the
Extension Term in question, the Lessee shall pay as annual Rent the same Rent as payable in the last year immediately preceding such Extension Term, with appropriate retroactive adjustments being made within thirty (30) days following the
delivery of a decision by the arbitrator. Save as required by Applicable Law, each Party undertakes to keep confidential all information regarding the existence of the arbitration, all disclosures made during the arbitration, all materials or
information 

  
 4 

	 	
created, used or produced for the purpose of the arbitration, as well as all awards and orders made by the arbitrator. This obligation of confidentiality extends to all materials or information
created, used or produced during any proceedings related to the arbitration, including, without limitation, any proceedings before the courts for injunctive relief, or proceedings to protect or pursue a legal right or enforce or challenge any award
or order made during the arbitration. The Parties agree to use their best efforts to impose confidentiality on all witnesses, including any expert witnesses, who will participate in the arbitration. The Parties will not, however, be liable for any
breach of confidentiality by any witness. The Party prevailing in the arbitration may enforce the award by any means permitted by Applicable Law, including entering the award as a judgment of any court. The place of the arbitration shall be
Montreal, Québec and the governing law of the arbitration will be the laws of the Province of Québec and the federal laws of Canada applicable in such province. The language of the arbitration and any written submissions shall be in
English. Provided and to the extent that they do not derogate from the foregoing, the provisions of the Code of Civil Procedure of Québec pertaining to arbitration will apply in addition to the foregoing provisions with respect to the
arbitration herein contemplated. 

  

	 	3.3	 Expiration of Lease 

This Lease expires ipso facto without notice or formal request on the expiration date stipulated in this Lease and no continued
occupation of the Leased Premises by the Lessee beyond this date may be construed as a tacit extension or renewal of the Lease for any term whatsoever, the whole notwithstanding the provisions of articles 1878 and 1879 of the Civil Code of
Québec, and the Lessee will be presumed to be occupying the premises against the wishes of the Lessor, who will henceforth be entitled to take all the measures provided by Applicable Law to evict the Lessee and obtain damages. 

 

	 	3.4	 Right to terminate 

The Tenant shall have a one-time right to terminate the Lease prior to the end of the Initial Term upon
the following conditions: 
  

	 	3.4.1	 No less than thirty (30) months of the Initial Term shall have lapsed. 

 

	 	3.4.2	 A change of control of the Tenant shall have occurred following said thirty (30) month period, other than
pursuant to a change of control set forth in section 11.14.6 hereof or an initial public offering. 

  

	 	3.4.3	 A twelve (12) month prior written notice to that effect shall have been received by the Lessor following
the occurrence of such change of control. 

  

	 	3.4.4	 A payment equal to the then unamortized portion of the leasehold improvements in the amount of $1,700,000 shall
be paid by the Lessee to the Lessor at the expiry of the twelve (12) month notice period and the Lessee shall have forfeited the Deposit in favour of the Lessor. 

 

	4	 RENT 

  
 5 

	 	4.1	 Rent 

During the Term, the Lessee will pay to the Lessor the Rent, in advance, in equal monthly instalments, on the first day of every month during
the Term. As such, the Lessee hereby authorizes the Lessor to withdraw, from the account described in Schedule A, every first (1st) day of each month during the Term the
monthly installment of the Rent. The first payment of the Rent will be made on the first day of the Term. If the Term begins on any day other than the first, or ends on any day other than the last, of a calendar month, Rent for the fractions of a
month at the beginning and at the end of the Term will be adjusted pro rata, on the basis of the actual number of days in those calendar months. 
  

	 	4.2	 Rent Adjustment 

Rent shall be increased on every anniversary of this Lease, according the Rent amount set forth in Schedule A for
each year of the Term. Rent, as so adjusted, shall thereafter be due as provided herein. Rent adjustments for any fractional calendar month shall be prorated. 
  

	 	4.3	 Tax Upon Rent 

The Lessee shall pay the Lessor the goods and services tax (GST), the Québec sales tax (QST) and any other similar tax that may
be put in force prior to or during the Term, imposed by any competent authority, that the Lessor must collect or may be asked to collect in respect of the Rent or any other amount payable to the Lessor or for the benefit of the Lessor under the
Lease or in respect of all goods, services or supplies that the Lessor may provide to the Lessee under the Lease. 
  

	 	4.4	 Insurance and Property Taxes 

This Lease is a gross lease, and as such, the Rent includes the Lessee’s proportionate share of the property taxes affecting the Leased
Premises of the Lessor. Notwithstanding the foregoing, the Lessee is responsible for all taxes imposed on property belonging to the Lessee, leasehold improvements, and on all other property placed by the Lessee on the Leased Premises. 

 

	 	4.5	 Late Payment 

All sums payable by the Lessee in virtue of this Lease, not paid at maturity, shall bear interest at the rate of ten percent (10%) per annum
calculated and compounded monthly until paid. 
  

	 	4.6	 Offset 

The Lessor is entitled, at its discretion, to apply or offset all amounts received from the Lessee or due to the Lessee in respect of any
amount due and payable by the Lessee under this Lease, notwithstanding any indication or instruction to the contrary by the Lessee, who agrees to said application or offset. 
  

	 	4.7	 Waiver of Compensation Right 

The Lessee hereby waives the right to compensation in respect of each and every claim or indemnity, present or future, against any rent or
other amounts due under this Lease. The Lessee agrees to pay the Rent and all other amounts due to the Lessor from time to time, irrespective of any claim, indemnification or compensation that the Lessee may seek or that a third party may claim on
the Lessee’s behalf, and without any reduction or deduction. 

  
 6 

	 	4.8	 Security Deposit 

The Lessee shall submit a deposit in an amount equal to three (3) months of Rent to the Lessor (the “Deposit”) in
accordance with the terms of Section 4.9 hereof, as security for the costs incurred by the Lessor which are the Lessee’s responsibility under this Lease and the faithful performance by the Lessee of the terms, covenants and conditions of
this Lease during the Term. The Deposit will be returned by the Lessor to the Lessee within thirty (30) days of the end of the Term provided the Lessee shall have then complied with the provisions of Section 5.20 hereof and shall not
otherwise then be in default hereunder, except that the Lessor may apply all or part of the Deposit as compensation for any loss or damage arising from the breach by the Lessee of any provision of this Lease. This right will not be construed to
limit the Lessor’s other rights under this Agreement or under Applicable Law or to limit the amount recoverable by the Lessor for damages in respect of breaches by the Lessee of this Lease. If the Lessor uses all or part of the Deposit, the
Lessee will, upon notification by the Lessor, remit to the Lessor the amount required to replenish the Deposit in respect of the amounts so applied. The Lessor will not be required to pay interest to the Lessee on any of the amounts paid to the
Lessor or retained by it under this Section. The Lessor may deliver the Deposit to any purchaser of the Lessor’s interest in this Agreement, whereupon the Lessor will immediately be discharged from any further liability with respect to the
Deposit. The Lessee will not assign, hypothecate or encumber its interest in the Deposit except in connection with a transfer permitted under Section 11.14 hereof, in which case the Lessee’s interest in the Deposit will be deemed to have
been assigned to the assignee as of the date of the transfer. The Deposit will not be governed by the provisions of Articles 2283 and following of the Civil Code of Québec and shall be considered as the property of the
Lessor and not of the Lessee. In the event of bankruptcy, insolvency or liquidation of the Lessee, the Lessor shall immediately have the right to confiscate the Deposit and to retain it as owner without prejudice to all of the Lessor’s other
rights and recourses. 
  

	 	4.9	 Prepaid Rent and Deposit 

The Lessee shall remit to the Lessor the aggregate amount of $1,700,000.00 (as indicated below) applicable as follows: 

 

	 	4.9.1	 As to $343,649.86, as a security deposit to be dealt with in accordance with the terms of Section 4.8
hereof.

month for the twenty-four (24) consecutive months as of the Commencement Date.

of credit issued by a Canadian chartered bank in the amount of $850,000.00 with an expiry date of not less than one (1) year. The Lessee shall remit to the Lessor on February 1, 2020 the amount of $850,000.00 and the Lessor shall
contemporaneously therewith remit the said letter of credit. In the event the Lessee fails or omits to remit the amount of $850,000.00 on February 1, 2020, the Lessor shall be entitled to hold the letter of credit and draw on it on or before
the expiry of the terms thereof (unless the Lessee shall have remitted such amount prior thereto) and apply the proceeds thereof in accordance with this section.

	 	5.8.8	 Prior to the Effective Date of this Lease, and thereafter, the Lessee shall provide the Lessor with
certificates attesting to the issuance and maintenance in effect of all insurance policies required pursuant hereto, immediately after the issuance of such insurance policies. If the Lessee fails to take out the insurance policy stipulated herein,

liabilities, civil convictions and fines, criminal convictions and fines, penalties, expenses (including all legal, judicial or extrajudicial fees and expenses), investigation, remediation, monitoring, cleaning and restoration costs or any other

  
 11 

	 	
damage arising from the failure of the Lessee (including its employees, contractors and agents and any other person for whom it is legally responsible) to comply with the obligations stipulated
herein, including any third party claim or enforcement action regarding the presence of Hazardous Materials at the Leased Premises or which has migrated therefrom to any property adjoining or in the vicinity of the Leased Premises or the Building.

apply and survive beyond the Lease Term and shall apply until expiration of the applicable prescription period. 

  

	 	5.10.4	 In addition to the foregoing, the Lessee agrees that: 

 

	 	(1)	 if it produces or introduces in or around the Leased Premises, any Hazardous Materials whatsoever or if the
conduct of its business entails the production or presence of any Hazardous Materials whatsoever in and around the Leased Premises, then, and notwithstanding any provision to the contrary in this Lease or the Applicable Law, such Hazardous Materials
will be and remain the exclusive property of the Lessee or its customers on behalf of whom the Lessee provides services and shall not become the property of the Lessor, notwithstanding the extent to which the Hazardous Materials or products
containing Hazardous Materials are integrated into the Leased Premises and notwithstanding the expiration or early termination of the Lease; 

  

	 	(2)	 upon expiration or early termination of the Lease, the Lessee shall, at its expense, remove and dispose of all
Hazardous Materials and all storage and other containers, in accordance with the Environmental Laws to the extent required by the Lessor, and in the case where such removal and disposal involves excavation work on the Leased Premises, in the
Building or on the Building, the Lessee shall return the Leased Premises or the Building, as the case may be, in the same condition in which it was found immediately prior to the excavation, using only earth or other clean, uncontaminated materials,
to the full satisfaction of the Lessor; 

  

	 	(3)	 Moreover, and subject to the other recourses of the Lessor pursuant hereto or under Applicable Law, should the
Leased Premises remain vacant or can only be partially occupied following termination of this Lease, directly or indirectly due to the failure of the Lessee to fulfill its obligations pursuant to this Section 5.10; then, notwithstanding such
Lease termination and in addition to all damages the Lessor may claim from the Lessee, the Lessee shall be deemed to continue occupying the Leased Premises on a monthly rental basis and shall be required to pay the Lessor Rent in advance at a
monthly rate equal to one hundred percent (100%) of the Rent payment for the last month of the Term. In the event the arrival of a new tenant is postponed by the delay incurred by this continued occupancy, the Lessee shall be required to pay the
Lessor Rent in advance at a monthly rate equal to two hundred percent (200%) of the Rent payment for the last month of the Term. Such rental on a monthly basis shall be deemed to continue until such time as the cleaning of the Leased Premises and
all repairs to the Leased Premises and/or the Building are completed, and the Leased Premises and/or the Building or any parts thereof are returned to their original condition. 

 

	 	5.10.5	 The Lessee agrees that it will not use Hazardous Materials in carrying out its activities, unless it complies

required authorizations in this regard from the competent authorities and where required, submit all required declarations to the relevant authorities.

	 	5.12	 Overload 

The Lessee may not install in or on the Leased Premises any machine, equipment or other object that by reason of its weight or size may cause
damage to the Leased Premises and it may not, in any event, overload the floors of the Leased Premises other than the NMR machine that the Lessee disclosed that it would be installing in the Leased Premises and for which the Lessor reinforced the
floors. If any damage is caused to the Leased Premises by any machinery, equipment or object other than the said NMR machine or as the result of any negligence or abuse on the part of the Lessee, its cleaning staff, agents or employees or any person
conducting business with the Lessee, the Lessee must, at the Lessor’s option, immediately repair the damage or pay the Lessor for the costs of repairs, without prejudice to any other recourse the Lessor may have under this Lease.

Lease without being entitled to claim damages, provided that the duration of major repairs stays within a reasonable delay which will take into account the nature and amount of repairs. 

 

	 	5.16	 Modifications, Additions and Improvements 

 

	 	5.16.1	 The Lessee may not make any structural or non-structural modifications
or improvements to the Leased Premises without prior submission of plans and specifications to the Lessor for which written consent may not be unreasonably refused.

	 	5.16.3	 If the Lessee wishes to make changes to these plans and specifications after they have been approved by the
Lessor, such changes shall be submitted to the Lessor for its written approval. 

  

	 	5.16.4	 If such plans are reasonably refused by the Lessor, (except in respect of the alterations, modifications or
repairs contemplated in Section 5.16.8, where the Lessor may refuse at its sole discretion), the Lessee shall make the appropriate corrections and resubmit the modified plans to the Lessor for approval; 

 

	 	5.16.5	 The Lessee is responsible for all costs incurred with respect to these modifications and improvements, plus a
10% administration fee, without any liability or obligation whatsoever being incurred by the Lessor. 

  

	 	5.16.6	 Upon expiration of this Lease, the Lessee must leave the Leased Premises in the condition in which they were
modified and/or improved; all modifications, additions or improvements become the property of the Lessor. The Lessee is not entitled to compensation or damages with respect to said modifications, additions or improvements. 

  
 14 

	 	5.16.7	 The Lessee is not entitled to enter into any deed or agreement that is likely to create or form the basis of a
lien, servitude, hypothec or other encumbrance on the Building of the Lessor or on any interest the Lessor may have in the Building or Leased Premises; If, as the result of an action or omission (or other alleged action or omission) on the part of
the Lessee, a hypothec or other lien is registered against the Building of the Lessor or the Leased Premises, the Lessee must at its own expense have such liens immediately radiated and cancelled. 

 

	 	5.16.8	 Notwithstanding the provisions of Section 5.16.1 hereof, the Lessee shall not, under any circumstances, be
authorized to make, without the prior written consent of the Lessor, which consent the Lessor may refuse in its sole discretion, alterations, modifications or improvements to the Leased Premises or install any equipment that (i) involves new
structures or additional structures to the Building, (ii) may affect or change, in any manner whatsoever, the exterior appearance of the Building, (iii) may affect the mechanical, electrical, heating, ventilation, air conditioning,
plumbing, control and sprinkler systems of the Leased Premises or the Building, or may affect any guarantee in respect of such systems or improvements, (iv) may, in any manner whatsoever, be considered a natural structure or that would

or (vii) fails to respect or is not in harmony with the master plan of the Technoparc Montreal and its design criteria, the whole as reasonably determined by the Lessor and its professionals. Moreover, insofar as the alterations, modifications
or improvements to be made by the Lessee would affect one of the preceding elements and the Lessee has obtained the prior written approval of the Lessor, the Lessee, in order to perform the work, shall use the contractors, subcontractors, architects
and engineers designated by the Lessor, the whole at the Lessee’s expense. 

  

	 	5.16.9	 Notwithstanding the provisions of Article 7 hereof and any obligation of the Lessor to make repairs and for any
reconstruction as stipulated in this Section, if a hypothecary creditor with an interest in an insurance benefit due to damage or destruction of the Building or the Leased Premises refuses to allow the use of such benefit for repairs, replacement,
reconstruction or restoration as stipulated above or for payment of amounts incurred or that will be incurred for such purposes, or if the damages or destruction are caused by a risk against which the Lessor is not insured, or if the insurance
benefits are not sufficient to cover all the costs of the reconstruction or repair (including professional fees and expenses, financing charges and other costs of a similar nature), or if fewer than two (2) years remain to the Term, then, in
the event of such damages or destruction, and provided that a written notice in each case was provided to the Lessee by the Lessor within thirty (30) business days following such damage or destruction, the obligation of the Lessor to repair or
rebuild, as stipulated above, shall come to an end and become null and void and the Lease shall terminate effective as of the first day following the date of the damage or destruction, unless the Lessor, in its sole discretion, concurrently with
this notice, notifies the Lessee that notwithstanding the decision of the hypothecary creditor or the absence or 

  
 15 

	 	
insufficiency of the insurance coverage, it decides to repair and rebuild, in which case the provisions of Article 7 will apply mutatis mutandis. If the Lease is terminated as
mentioned above, the Rent and any other amounts payable by the Lessee pursuant to the Lease provisions will be adjusted accordingly and the Lessee shall be responsible for the full payment of such Rent until the date of such damage or destruction.

  

	 	5.16.10	 No clauses hereof shall obligate the Lessor to repair, replace or rebuild any alteration, addition,
installation, modification, improvement, work of the Lessee or any other improvement or asset of the Lessee. 

  

	 	5.16.11	 If the Lessor repairs the Leased Premises as stipulated herein, the Lessee will be obligated to promptly and
diligently repair, replace or rebuild its alterations, additions, installations, modifications, improvements, the work of the Lessee as well as the assets located in the Leased Premises prior to such damage or destruction, such that the Lessee can
use and occupy the Leased Premises, and in all cases the Lessee shall repair, replace or rebuild them within sixty (60) days of the date on which the Lessor completed its work. Notwithstanding all the provisions of Article 7 to the contrary, if
the Lessee fails to complete these repairs, replacements or reconstruction within the sixty (60) days mentioned above, the total Rent will still be payable upon expiration of this deadline, without any reduction or deduction.

  

	 	5.17	 Access to Premises 

 

	 	5.17.1	 The Lessor and its representatives will have the right, at any reasonable time during the Term and following a
reasonable notice to the Lessee (except in emergency situations where no notice is required), to enter the Leased Premises to examine the condition of the Leased Premises. 

 

	 	5.17.2	 The Lessor may at any time, without prior notice to the Lessee, perform emergency minor repairs and invoice the
cost to the Lessee, which are the Lessee’s responsibility pursuant to this Lease. The Lessor acknowledges the confidential nature of the activities of the Lessee in the Leased Premises and undertakes, when its employees or any persons under its
control have access to the Leased Premises, to take reasonable measures to preserve this confidentiality. 

  

	 	5.17.3	 During the last six (6) months of this Lease, the Lessee must permit prospective tenants to visit the

	 	5.18.1	 Both Parties agree that the Lessor is responsible for the preparation of the first draft of the Lease. Both
Parties agree that they are each responsible for their share of legal fees incurred in the negotiation of the Lease. Furthermore, neither Party may incur such legal fees, payable by the other Party, without having obtained prior written permission
of the latter. 

  

	 	5.18.2	 The Lessee acknowledges that is has dealt with no other broker other than CBRE regarding the proposed Lease.

 16 

	 	
Lessor shall be responsible for any compensation to CBRE in connection with the negotiation and execution of the Lease between the Lessor and the Lessee. No other broker or agent shall negotiate
or participate in the negotiation or execution of the Lease between the Lessor and the Lessee. 

  

	 	5.19	 Non-Responsibility of the Lessor 

 

	 	5.19.1	 The Lessee releases from liability and holds the Lessor harmless from all damages or losses caused directly or
indirectly to the property, merchandise or operations of the Lessee on the Leased Premises, caused by the occupants of adjacent premises by reason of a fallen wall, plaster or ceiling, snow, or rain or by reason of a heating unit, humidity or flood;
the Lessor must however appropriately maintain the Leased Premises and take the necessary measures to prevent or repair any defects when so notified. 

  

	 	5.19.2	 Except for gross negligence, the Lessor, its agents, representatives, employees or contractors shall not be
held liable for any damage caused to the Leased Premises or its contents as a result of entry on the Leased Premises by the Lessor, its agents, representatives, employees or contractors for inspection purposes or to carry out any work whatsoever, or
in the case of an emergency. 

  

	 	5.19.3	 It is further agreed that the Lessee releases the Lessor from all liability that may result from the
interruption of services in the Building, provided the Lessor takes all necessary steps to restore such services with all due diligence. Therefore, the Lessee hereby expressly waives the right to all damages resulting from loss of enjoyment of the
Leased Premises subject to Section 6.1 of this Lease. 

  

	 	5.19.4	 The Lessee releases the Lessor from all liability resulting from the use by the Lessee of equipment and
instruments provided by Lessor or on its behalf; the Lessor must, however, maintain such equipment and instruments in good working order, and take all necessary measures to repair same when so notified. 

 

	 	5.19.5	 Save in the event of the gross negligence of the Lessor, the Lessor shall, under no circumstances, be held
liable in any manner whatsoever for any losses, costs, damages or expenses, whether direct or indirect, arising from any interruption in the provision of any service or additional service regardless of their nature. The Lessee shall not be entitled,
following any such interruption, to obtain compensation or reduction in Rent or be entitled to terminate the Lease. The Lessor may interrupt the use or provision of any service when necessary following an accident, defective operation, or in
accordance with any Applicable Laws, or during any repairs, improvements or rebuilding that the Lessor deems necessary. 

  

	 	5.20	 Return of Leased Premises 

 

	 	5.20.1	 Upon expiration or early termination of the Lease, the Lessee shall peacefully return to the Lessor, the vacant
possession of the Leased Premises as well as all leasehold improvements, additions, modifications, changes or construction that, at all times prior to or during the Lease Term, will be or were made to the Leased Premises,

  
 17 

	 	
in a good condition, with the exception of normal wear and tear, the whole, without the Lessee or any other person claiming any compensation whatsoever. 

 

	 	5.20.2	 The Lessee may, during the Lease Term, remove its machinery and equipment during the normal course of business,
provided that such equipment and machinery exceed the needs of the Lessee, or provided that the Lessee replace said equipment and machinery with similar new equipment, and provided that in each case the Lessee is not in default under the terms of
this Lease and that removal does not constitute a breach of the clauses hereof. The machinery and equipment of the Lessee does not include: a) the heating, ventilation or air conditioning systems; b) machinery, installations and equipment located in
or serving the Leased Premises or incorporated therein or into the Building or that cannot be removed without damaging the Leased Premises or the Building; c) floor coverings, light fixtures and doors; d) which machinery and equipment are all deemed

	 	5.20.3	 The Lessee shall, upon expiration or early termination of the Lease, return the Leased Premises in the
condition in which the Lessee is required to maintain them pursuant to the terms of this Agreement, with the exception of normal wear and tear, and remove its machinery and equipment, and repair all damages caused by such removal.

  

	 	5.20.4	 Furthermore, the Lessee shall, upon expiration or early termination of the Lease, immediately remove at its
expense the alterations, modifications, additions, installations and improvements made by the Lessee or by the Lessor for the Lessee prior to or following the Effective Date and repair all damages caused by such installation or removal. Any
equipment or machinery or other property left by the Lessee in the Leased Premises upon expiration or early termination of the Lease shall become the sole property of the Lessor, without the Lessee or any other person claiming any compensation
whatsoever. The Lessor may dispose of such equipment or machinery in any manner it deems appropriate. The obligations of the Lessee of this Sub-Section shall survive the expiration and early termination of the
Lease. 

  

	 	5.20.5	 For greater certainty, the provisions included in this Section 5.20 do not increase Lessee’s
obligations set forth under Sections 5.13, 5.14, 5.15 and 5.16. 

  

	 	5.21	 Alternative Execution 

 

	 	5.21.1	 It is hereby expressly understood and agreed that if, at any time and as often as the situation arises, the
Lessee fails to fulfill or execute any of its obligations under the terms of this Lease, the Lessor may, without excusing or releasing the Lessee from such obligations, itself respect and fulfill said obligation or obligations of the Lessee.

  

	 	5.21.2	 In this regard, the Lessor may pay the amounts required or deemed necessary and subsequently collect from the
Lessee such amounts plus applicable interest charged from the date on which the Lessor paid said amounts, at the interest rate agreed to herein as additional rent; the Lessee undertakes to immediately reimburse all such expenses as well as the
applicable interest on such amounts at the agreed upon rate.

plumbing systems in good working condition (collectively, the “Lessor’s Work”). Any amendments to the specifications described on Appendix 6.1 shall be agreed to by the Lessor and the
Lessee, prior to the Lessor commencing the Lessor’s Work. 

  

	 	6.1.2	 The Lessor’s Work shall be performed in a good and workmanlike manner, in compliance with all Applicable
Laws and Lessor shall obtain and keep in full force and effect and in good standing, at its own cost, all approvals and permits from authorities having jurisdiction in respect thereof. Any work in addition to any of the items specifically enumerated
as Lessor’s Work shall be performed at the own costs and expenses of the Lessee. 

  

	 	6.1.3	 The Lessee and the Lessor and their respective professional consultants will tour the Leased Premises thirty
(30) days prior to the Commencement Date in order to review whether substantial completion of the Lessor’s Work is on schedule. Within ten (10) days following the inspection, the architect shall identify and list deficiencies in the
Lessor’s Work, which list shall be provided to the Lessor and the Lessee (the “Deficiency List”). The Deficiency List shall be accompanied by a letter from the architect certifying that the Lessor has achieved substantial
completion of the Lessor’s Work, subject to any deficiencies that are identified in the Deficiency List. Lessor will promptly provide a timeline satisfactory to the Lessee for rectification by the Lessor of all deficiencies identified in the
Deficiency List. The Lessor will proceed forthwith to diligently rectify such deficiencies at its sole cost, provided that those minor deficiencies which do not materially interfere with the utilization of the work in question for such purpose (as
determined by the Lessee, acting reasonably) may be rectified after the Commencement Date, in which case the Lessor will coordinate with the Lessee in order to correct such deficiencies so as to interfere as little as reasonably possible with
Lessee’s use and enjoyment of the Leased Premises.

such delay, for any month of delay, 125% of the monthly Rent set forth herein; and 

  

	 	(c)	 if for any reason the Lessor is unable to provide substantial completion of the Lessor’s Work by December
31st, 2020, the Lessee but not the Lessor shall have the right at any time thereafter until a certificate of substantial completion of the Lessor’s Work is issued by the architect but no
later, by written notice to the Lessor, to terminate this Lease at no cost, penalty or compensation by the Lessee and Lessor shall be liable to Lessee for the liquidated damages set forth in Subsection (b) only. Should the Lessee not exercise
its termination right during the aforesaid prescribed period, then such termination right shall be automatically null and void and of no further force or effect. 

 

	 	6.1.5	 Notwithstanding any other provision of this Lease, the Lessee shall benefit from a six (6) month period
from the substantial completion (the “Warranty Period”) to notify the Lessor in writing of any visible, hidden or apparent defect affecting the Lessor’s Work or the Leased Premises and the Lessor shall promptly correct any such
defect at its sole costs. At the expiry of the Warranty Period, except for the defects or required repair or replacement disclosed in writing to the Lessor, the Leased Premises shall be deemed to be in good and satisfactory order.

	 	(a)	 the Building shall comply with all Applicable Laws, including all applicable Environmental Laws;

  

	 	(b)	 the Building shall be free of any Hazardous Materials which are in violation of any applicable Environmental
Laws and that no Hazardous Material in violation of any applicable Environmental Laws shall have migrated from any adjoining property into the Building; and 

  

	 	(c)	 the Building and all buildings, structures, improvements, facilities, equipment and Building systems shall be
in brand new operating condition and order and shall be adequate and suitable for operation by Lessee. 

  

	 	6.1.7	 Change Orders 

  

	 	6.1.8	 Any changes to the scope of work to be performed by the Lessor under the terms hereof requested by the Lessee
shall be at its sole costs and be payable upon approval by the Lessee of a change order to be delivered by the Lessor to the Lessee reflecting such requested change. 

 

	 	6.2	 Peaceable Enjoyment

	 	6.4	 HVAC 

  

	 	6.4.1	 The Lessor must heat the Building, Common Facilities and the Leased Premises and, when and as required, must

	 	6.4.2	 Notwithstanding the foregoing, the Lessee shall have the right to override and control the HVAC system of the

against payment upon presentation by the Lessor of a monthly statement of account to this effect. The Lessee undertakes and agrees to procure such services exclusively with the Lessor. This obligation stems from the business model of the Lessor, the
presence of facilities specifically designed for this purpose, and from the signing of sponsorship agreements with preferred suppliers that give access to preferable rates. 

 

	 	(1)	 collection, segregation and safe elimination of biomedical, chemical and radioactive waste. For such services,
the Lessee agrees to pay the Lessor, upon receipt of the statement of account to this effect, all the costs of the additional services, plus ten percent (10%) in administration charges;

	 	6.6.1	 The Lessor hereby undertakes to make any major repairs required to the Leased Premises and assume all costs.
The Lessor will coordinate the execution of all major repairs and of all external specialists required to complete such major repairs. 

  

	 	6.6.2	 The Lessor will give to the Lessee, as soon as possible, a prior notice before the commencement of the work.
The Lessor will submit to the Lessee regular written notices stating the progress of the repairs. 

  

	 	6.7	 Signs 

  
 22 

 The Lessor hereby undertakes to provide the installation of standardized signs for both
tenants and suites in the interior and exterior of the Building. All other signs must be approved by the Lessor. 
  

	7	 FIRE AND DESTRUCTION OF LEASED PREMISES 

7.1    If, during the Term, the Building is completely destroyed or damaged to such an extent that it is rendered
completely unusable for any purpose whatsoever, the Lessor may, within sixty (60) days of the occurrence of said disaster, notify the Lessee of its intention to rebuild or repair the Building, in which case, provided that the Lessee cannot be
held liable for the damages suffered, the Rent payable by the Lessee will be reduced in proportion to the diminution in the Lessee’s peaceable enjoyment until such time as the reconstruction and repairs are terminated, in which case the Lessee
may not request termination of this Lease nor seek any indemnification, damages or other form of compensation from the Lessor. Should the Lessor fail to inform the Lessee of its intention to proceed with the above-mentioned reconstruction or repair
of the Leased Premises, this Lease will be regarded as having terminated on the date of the destruction or damage, without any recourse whatsoever by the Lessee against the Lessor. 

7.2    If, during the term of this Lease, the Building is only partially destroyed or damaged and requires extensive
repairs but the Leased Premises are not destroyed or rendered unusable, the Lessor may, at its option: 
  

	 	7.2.1	 terminate this Lease within thirty (30) days of the occurrence of the destruction or damage by virtue of
the option to this effect hereby conferred by the Lessee, by manifesting its intentions in writing in which case, the Lease automatically terminates five (5) days following the receipt by the Lessee of the above-mentioned notice and the Lessee
is not entitled to claim any indemnity, damages or other form of compensation whatsoever from the Lessor; or 

  

	 	7.2.2	 within the same delay, notify the Lessee of its intention to rebuild or repair the Building, in which case the
Lessee must endure the repairs without any reduction in Rent for the duration of the reconstruction or repairs and is not entitled to request termination of this Lease or claim any indemnification, damages or any other form of compensation
whatsoever from the Lessor. In this case, the Lessor will complete the repairs within a reasonable delay which will take into account the nature and amount of the repairs. The Lessor will submit to the Lessee regular written notices stating the
progress of the repairs. 

 7.3    If, during the term of this Lease, the Leased Premises are totally
destroyed or damaged to such an extent that they are rendered completely unusable, the Lessee must notify the Lessor in writing of the occurrence of such destruction or damage and the Lessor may then within sixty (60) days of receipt of said
notice inform the Lessee of its intention to rebuild or repair, in which case and provided that the Lessee can in no way be held liable for the damages, the Rent payable by the Lessee will be reduced in proportion to the diminution in peaceable
enjoyment of the Leased Premises until such time as the reconstruction or repairs are completed. The Lessee will not be entitled to claim any indemnification, damages or any other form of compensation whatsoever from the Lessor. Should the Lessor
fail to inform the Lessee of its intention to proceed with the above-mentioned reconstruction or repair of the Leased Premises, this Lease will be regarded as having terminated on the date of the destruction or damage, without any recourse
whatsoever by the Lessee against the Lessor. 

  
 23 

 7.4    If, during the term of this Lease, the Leased Premises are only
partially destroyed or damaged, the Lessee must immediately notify the Lessor in writing and the Lessor may then, within sixty (60) days of receipt of this notice: 
  

	 	7.4.1	 terminate this Lease by virtue of the option hereby granted by the Lessee by manifesting its intentions to this
effect by given written notice to the Lessee, in which case, the Lease automatically terminates on the first day of the month following receipt by the Lessee of such notice and the Lessee is not entitled to claim any indemnification, damages or any
other form of compensation whatsoever from the Lessor; or 

  

	 	7.4.2	 notify the Lessee of its intention to rebuild or repair the Leased Premises in which case, provided the Lessee
cannot be held liable for the damages suffered, the Rent payable by the Lessee will be reduced in proportion to the diminution in peaceable enjoyment that it must endure until completion of the reconstruction or repairs and the Lessee is not
entitled to claim any indemnification, damages or other any other form of compensation whatsoever from the Lessor. 

  

	8	 RIGHT OF FIRST OPPORTUNITY 

8.1    Provided (i) this Lease is then in full force and effect, (ii) the Lessee is itself in occupancy and
carries on business in and from the entirety of the Leased Premises, and (iii) the Lessee is not in default in the performance of its obligations under this Lease, during the Term of the Lease: 

 

	 	8.1.1	 the Lessor will notify the Lessee quarterly (the “2nd Floor ROFO Notice”) if,
and only if, any space (the “2nd Floor ROFO Space”) that comprises all or any portion of the second (2nd) floor of the Building is available for lease. The Lessor
shall have no obligation to notify the Lessee if no such 2nd Floor ROFO Space is available for lease. The 2nd Floor ROFO Notice shall include the terms and conditions the Lessor is willing to accept for the lease of the 2nd Floor ROFO Space. The
Lessee shall have an ongoing right of first opportunity to lease the 2nd Floor ROFO Space during the Term by delivering to the Lessor, within ten (10) business days of receipt of the 2nd Floor ROFO Notice, a written offer to lease the 2nd Floor
ROFO Space upon the terms and conditions provided in the 2nd Floor ROFO Notice, failing which the Lessor is free to accept the third party offer at any time before the next quarter on terms that are not more favorable to the tenant thereunder than
those that were included in the most recent 2nd Floor ROFO Notice. 

  

	9	 RIGHT OF FIRST REFUSAL 

9.1    Provided (i) this Lease is then in full force and effect, (ii) the Lessee is itself in occupancy and
carries on business in and from the entirety of the Leased Premises, and (iii) the Lessee is not in default in the performance of its obligations under this Lease, during the Term of the Lease: 

 

	 	9.1.1	 the Lessor will notify the Lessee (the “Phase II ROFR Notice”) if it receives an offer from a
bona fide third party which the Lessor is prepared to accept for any entire floor (the “Phase II ROFR Space”) that comprises the Phase II. The Lessee shall have an ongoing right

  
 24 

	 	
of first refusal to lease the Phase II ROFR Space during the Term by delivering to the Lessor, within ten (10) business days of receipt of the Phase II ROFR Notice, a written offer to lease
the Phase II ROFR Space upon the same terms and conditions than the third party offer, failing which the Lessor is free to accept the third party offer.

authorization; 

 In each of the above-mentioned cases, the Lessor may, without notice or any other form of legal
proceeding, immediately enter the Leased Premises and retake possession, and remove the Lessee’s effects from the Leased Premises. Furthermore, the full amount of the Rent for the current month and the following three (3) consecutive
months become immediately due and payable; furthermore, the Lessor is immediately entitled to claim this amount, as well as all arrears and all other amounts that may be owing to the Lessor by the Lessee under the terms of this Lease, without

	 	10.2.4	 the Lessee assigns this Lease or sub-leases the Leased Premises or
permits a third party to occupy the Leased Premises without obtaining the Lessor’s prior authorization, as required under this Lease; 

  

	 	10.2.5	 any insurance policy of the Lessee covering any part of the Leased Premises is cancelled or adversely changed
or is not renewed as a result of any use or occupancy of the Leased Premises, or the Lessee acts in a manner or permits the occurrence of anything that would result in the possible cancellation of an insurance policy on the Leased Premises, and does
not take the necessary steps to remedy this occurrence, within the time prescribed by the insurer’s written notice to that effect;

 Where the Lessor is in default, the Lessee is entitled, at its option, to request a
reduction in Rent, or terminate the Lease at a date of its choosing without prejudice to all of its other legal rights and remedies.

	11	 GENERAL DISPOSITIONS 

 

	 	11.1	 Lessee’s Current Lease

transferee who would agree to sublease or take over the Lessee’s current lease at 7210 Frederick-Banting Street, Suite 100, Saint-Laurent, Province of Québec. Notwithstanding the foregoing, in the event the Parties, working in good
faith, are unable to find said subtenant or transferee, the Lessor shall bear no responsibility. The Lessor and the Lessee acknowledge that the Lessee has entered into an agreement with CBRE as of the Effective Date whereby CBRE has agreed to act as

	 	11.4	 Governing Laws and Jurisdiction

	 	11.4.2	 The Parties hereby elect domicile before the court of competent jurisdiction in the judicial district of

	 	11.5	 Headings.

without limitation, any act of God, strike, partial or total work stoppage, lock-out, fire, riot, civil or military intervention or any mandatory compliance with regulations or ordinances issued by a
government authority and any act of war (declared or undeclared). 
  

	 	11.10	 Severability 

If any provision of this Lease is determined to be invalid or unenforceable in whole or in part, such invalidity or unenforceability shall
attach only to such provision or part of such provision and the remaining part of such provision and all other provisions of this Lease shall continue in full force and effect. 

 

	 	11.11	 Enurement 

This Lease will enure to Parties hereto, their legal representatives, successors and permitted assigns. 

 

	 	11.12	 Prevalence 

  

	 	11.12.1	 The Parties agree that the provisions of the Lease shall, at all times and in all manner, prevail over any
provision of the Civil Code of Québec or any law contrary to or incompatible with a provision hereof, more specifically but without limitation in respect of i) the time limits granted to remedy a default, ii) any
obligation of delivery or guarantee by the Lessor, iii) any obligation of any of the Parties in respect of the intended use of the Leased Premises or repairs, replacements or maintenance of the Leased Premises, iv) the time limit to respond to a
request to assign the Lease of the Leased Premises or to sublease the Leased Premises, v) the release of the Lessee in case of a Lease assignment, vi) the tacit renewal of said Lease or vii) returning the Leased Premises in its original condition
upon expiration of the Lease, the Parties expressly waiving the right to invoke any provision of any law to the contrary effect. 

  
 28 

	 	11.12.2	 Notwithstanding Sections 1878 and 1879 of the Civil Code of Québec or any law or
custom to the contrary effect, the Lease shall not be subject to a tacit renewal, and the Lessee shall not be entitled to occupy the Leased Premises after the end of the Lease Term unless the Lessor and the Lessee agree in writing prior to its
termination on the terms and conditions of a Lease renewal or extension. 

  

	 	11.12.3	 If the Lessee retains possession of the Leased Premises following the termination of the Lease Term without any
written agreement to this effect, as stipulated above, the Lessee shall be deemed to occupy the Leased Premises against the will of the Lessor and only on a monthly basis at a rate equal to two hundred percent (200%) of the Rent payable for the last
month of the Lease Term, which amount shall be payable in advance, subject to the right of the Lessor to enter the Leased Premises, take possession and evict the Lessee without notice or indemnity payable to the Lessee and subject to the other
recourses of the Lessor pursuant hereto or under Applicable Law. 

  

	 	11.13	 Further Assurance 

 

	 	11.13.1	 At the request of the Lessor or any third party the Lessee must promptly execute all the documents or
certificates deemed necessary or useful by the Lessor to give effect to any and all dispositions of this Lease. 

  

	 	11.13.2	 If the Lessee fails to execute the above documents or certificates within a reasonable delay, the Lessee
irrevocably designates the Lessor as its representative with full powers and authority to execute and deliver in the Lessee’s name any such documents or certificates. 

 

	 	11.14	 Change of Control, Assignment and Sublease 

 

	 	11.14.1	 The Lessee may not assign this Lease, in whole or in part, or sublease, in whole or in part, the Leased
Premises, without the prior written consent of the Lessor, not to be unreasonably withheld, unless the assignment or sublease is made in favor of a wholly-owned subsidiary of the Lessee. For the purpose of the Lease, a change of control of the
Lessee will be deemed an assignment to which this Section applies mutatis mutandis. 

  

	 	11.14.2	 If the Lessee wishes to assign or sublease the Leased Premises, or transfer this Lease in any other manner, in
whole or in part, or any interest therein, the Lessee must in each and every case provide the Lessor with prior written notice of its intention, designating the proposed assignee, sub-lessee or occupant; the
Lessor must, within thirty (30) days of the notice, advise the Lessee in writing that it a) consents, or b) refuses to consent to the aforementioned assignment or sublease. The Lessor’s silence may, at no time, be interpreted as
constituting consent to the transfer requested by the Lessee. 

  

	 	11.14.3	 Without limiting the generality of the foregoing, in determining whether or not to grant its consent, it shall
not be unreasonable for the Lessor to withhold its consent if: 

  

	 	a)	 the Lessee is in default under this Lease beyond any applicable grace or cure period; 

  
 29 

	 	b)	 in the Lessor’s opinion, arrived at in good faith, the transferee or any principal or principal
shareholder of the transferee: (i) does not have a history of successful business operations in the business to be conducted in the Leased Premises; (ii) does not have a good credit rating; (iii) has a history of defaults under
commercial leases; (iv) does not carry business in life science; or (v) the Lessor does not receive such financial, business or other information relating to the proposed transferee and its principals as the Lessor reasonably requires to
enable it to make a determination concerning the matters set out in this Section. 

  

	 	11.14.4	 Notwithstanding any assignment or sublease, the Lessee remains solidary liable for this Lease and is not
relieved of its obligation to execute the terms, conditions and clauses of this Lease, including, without limiting the generality of the foregoing, the obligation to make all rent payments due under this Lease. 

 

	 	11.14.5	 Any assignment of this Lease agreed to by the Lessor must be prepared by the Lessor or its attorneys, and all
reasonable legal fees relating to this assignment must be assumed by the Lessee. Any consent granted by the Lessor is subject to the Lessee’s obligation to ensure that any assignee or sub-lessee agrees to
be bound by all the terms, conditions and clauses in this Lease, as though the assignee or sub-lessee had originally signed this Lease as Lessee. 

 

	 	11.14.6	 Notwithstanding the foregoing provisions, a change of control resulting from the transfer, assignment or sale
of the voting shares of the Lessee by and between present and future shareholders of the Lessee that are venture capital funds shall not be deemed an assignment to which this Section applies. For the purposes hereof a “venture capital
fund” shall mean a widely held fund which is not directly or indirectly controlled by a public pharmaceutical company nor by any one entity in particular. 

 

	 	11.15	 Registration 

The Lessee may register a notice of this lease pursuant to article 2999.1 of the Civil Code of Quebec without the consent of the Lessor.

  

	 	11.16	 Transfer by Lessor 

The Lessor may, at any time and without the consent of the Lessee, sell, assign, transfer, lease, hypothecate, charge, encumber or otherwise
deal with the whole or any part of its interest in the Leased Premises (subject always to this Lease and the rights of the Lessee hereunder) and all of its, right, title and interest in this Lease and the Rent payable hereunder. 

 

	 	11.17	 Status Statement 

The Lessee shall, within five (5) business days after receipt of written request from the Lessor, execute an acknowledgement or
certificate in favour of any actual or prospective purchaser, creditor or encumbrancer, acknowledging or certifying as to the status of this Lease, as to any modifications thereof, as to any breaches of covenant known to the Lessee and as to the
state of the Rent account, and such other matters 

  
 30 

 
as may be reasonably requested by the Lessor, with the intent that any such acknowledgement or certificate may be relied upon by the person to whom it is addressed. 

 

	 	11.18	 Declarations 

  

	 	11.18.1	 The Parties hereby expressly declare and acknowledge that the provisions of this Lease have not been
unilaterally imposed by either of them but have instead been freely negotiated. 

  

	 	11.18.2	 Furthermore, each Party has obtained an adequate explanation as to the nature and scope of each clause of this
Lease and has had reasonable opportunity to have these clauses reviewed by its legal advisor and declares it is satisfied with the legibility and clarity of said clauses. 

 

	 	11.18.3	 Lastly, each Party hereby declares and acknowledges that each clause in this Lease, including those that impose
penalties or restrictions, is reasonable and necessary for the protection of their respective interests. 

  

	 	11.18.4	 In consideration of the foregoing, each Party hereby expressly waives the right to invoke the nullity of any
clause of this Lease on the grounds that it is incomprehensible, illegible or abusive. 

  

	 	11.19	 Language 

The Parties hereto confirm that it is their wish that this Agreement be drawn up in English only. Les parties aux
présentes confirment leur volonté que cette convention soit rédigée en anglais seulement.

on behalf of the Bankrupt Party and upon written request by the Non-Bankrupt Party. All rights, powers and remedies of a Non-Bankrupt Party hereunder are in addition to
and not in substitution for any and all other rights, powers and remedies now or hereafter existing at Law in the event of the commencement of a proceeding under a Bankruptcy Code with respect to the Bankrupt Party. The Parties agree that, in
addition to the foregoing rights, they intend for the right to contract directly with any Third Party to perform any obligations of the Bankrupted Party hereunder and complete such contracted work to apply to the maximum extent permitted by law and
to be enforceable under the Bankruptcy Code. This Agreement shall be effective before, during and after the commencement of any bankruptcy or insolvency proceeding under the Bankruptcy Code. The provisions of this Agreement shall be binding on any

SPECIFIC OBLIGATIONS UNDER THE NYU AGREEMENT 

The following Sections are excerpted from the NYU Agreement and shall be applicable to this Agreement with: (i) Ono having the rights and obligations of
a “sublicensee” under the following provisions and (ii) this Agreement constituting a “sublicense” for purposes of the following provisions: 

5.05 Repare shall be entitled to grant sublicenses under the License on terms and conditions in compliance and are materially consistent with
the terms and conditions of this Agreement (i) to Affiliates or (ii) to Third Parties, in each case for consideration and in an arms- length transaction. All sublicenses shall only be granted by Repare under a written agreement, a copy of
which shall be provided by Repare to NYU as soon as practicable after the signing thereof. Each sublicense granted by Repare hereunder shall be subject and subordinate to the terms and conditions of this License Agreement and shall contain
(inter-alia) the following provisions: 
  

	 	(1)	 the sublicensee may have step-in rights, whereby a sublicensee could
cure a breach of this Agreement by Repare during the cure period provided in Section 15.02, and thereafter the sublicense granted hereunder would continue as provided in Section 15.03; provided that in all other circumstances, the
sublicense would terminate at the end of such cure period; 

  

	 	(2)	 the sublicense shall not be assignable, in whole or in part; 

 

	 	(3)	 the sublicensee shall be able to grant further sublicenses thereunder subject to the term of this
Section 5.05; and 

  

	 	(4)	 both during the term of the sublicense and thereafter the sublicensee shall agree to a confidentiality
obligation similar to that imposed on Repare in Section 9 below, and that the sublicensee shall impose on its employees, both during the terms of their employment and thereafter, a similar undertaking of confidentiality; and

  

	 	(5)	 the sublicense agreement shall include the text of Sections 13 and 14 of this Agreement and shall state that
NYU is an intended Third Party beneficiary of such sublicense agreement for the purpose of enforcing such indemnification and insurance provisions. 

Repare shall not be subject to the provisions of this Section 5.05 with respect to agreements with a distributor or to a contractor or a subcontractor to
the extent the purpose is manufacturing, research and development, packaging and distributing and other similar services for which such services are compensated by Repare (the “Excluded Sublicensees”). 

 13. Liability and Indemnification. 

13.1 Repare shall indemnify, defend and hold harmless NYU and its contractors and each of their affiliates, and each of their trustees, officers, medical and
professional staff, employees, students and agents and their respective successors, heirs and assigns (the “Indemnitees”), against any liability, damage, loss or expense (including reasonable attorneys’ fees and expenses of
litigation) incurred by or imposed upon the Indemnitees or any one of them in connection with any claims, suits, actions, demands or judgments (i) arising out of the design, production, manufacture, sale, use in commerce or in human clinical
trials, lease, or promotion by Repare or by a licensee, Affiliate or agent of Repare of any Licensed Drug Candidate and Licensed Product, process or service relating to, or developed pursuant to, this Agreement or (ii) arising out of any other
activities to be carried out pursuant to this Agreement. 
 13.2 With respect to an Indemnitee, Repare’s indemnification under subsection 13.01(i)
shall apply to any liability, damage, loss or expense whether or not it is attributable to the negligent activities of such Indemnitee. Repare’s indemnification obligation under subsection 13.01(ii) shall not apply to any liability, damage,
loss or expense to the extent that it is attributable to the fraud, willful misconduct or grossly negligent activities of NYU or any Indemnitees or otherwise arising from NYU’s breach of any representation, warranty or covenant of this
Agreement. 
 13.3 Repare agrees, at its own expense, to provide attorneys reasonably acceptable to NYU to defend against any actions brought or filed
against any Indemnitee with respect to the subject of indemnity to which such Indemnitee is entitled hereunder, whether or not such actions are rightfully brought. 

14. Insurance. 
 14.1 At such time as any Licensed Product,
process or service relating to, or developed pursuant to, this Agreement is being commercially distributed or sold or tested in clinical trials by Repare or by a licensee, Affiliate or agent of Repare, Repare shall at its sole cost and expense,
procure and maintain policies of comprehensive general liability insurance in amounts not less than (i) $[***] per incident and $[***] annual aggregate during the period that such Licensed Product, process, or service is being tested in clinical
trials prior to commercial sale, and (ii) $[***] per incident and $[***] annual aggregate, during the period that such Licensed Product, process, or service is being commercially distributed or sold, and in each case naming the Indemnitees as
additional insureds. Such comprehensive general liability insurance shall provide (i) product liability coverage and (ii) broad form contractual liability coverage for Repare’s indemnification under Section 14 of this Agreement.
If Repare elects to self-insure all or part of the limits described above including deductibles or retentions which are in excess of U.S. $[***] annual aggregate such self-insurance program shall include assets or reserves which have been
actuarially determined for the liabilities associated with this Agreement and shall be reasonably acceptable to NYU. 
 The minimum amounts of insurance
coverage required under this Section 14 shall not be construed to create a limit of Repare’s liability with respect to its indemnification under Section 13 of this Agreement. 

14.2 Repare shall provide NYU with written evidence of such insurance upon request of NYU. Repare shall provide NYU with written notice at least [***] prior
to the cancellation, non-renewal or material change in such insurance; if such insurance is terminated or no longer in compliance with this Section 14, and Repare does not obtain replacement insurance NYU
shall have the right to terminate this Agreement without notice or any additional waiting periods. 

 14.3 Repare shall maintain such comprehensive general liability insurance beyond the expiration or
termination of this Agreement during (i) the period that any product, process or service, relating to, or developed pursuant to, this Agreement is being commercially distributed or sold or tested in clinical trials by Repare or by a
sublicensee, Affiliate or agent of Repare and (ii) statute of limitations applicable to such activities. 
 15. Expiry and Termination 

15.1 Unless earlier terminated pursuant to this Section 15, hereof, this Agreement shall expire upon the expiration of the period of the License in all
countries as set forth in Section 5.04 above. 
 15.2 At any time prior to expiration of this Agreement, either Party may terminate this Agreement
forthwith for cause, as “cause” is described below, by giving written notice to the other Party. Cause for termination by one Party of this Agreement shall be deemed to exist if the other Party materially breaches or defaults in the
performance or observance of any of the provisions of this Agreement and such breach or default is not cured within [***] or, in the case of failure to pay any amounts due hereunder, [***] (unless otherwise specified herein) after the giving of
notice by the other Party specifying such breach or default and provided such breach or default is not cured, or if either NYU or Repare discontinues its business or becomes insolvent or bankrupt. 

15.3 Upon termination of this Agreement for any reason and prior to expiration as set forth in Section 15.01 hereof, all rights granted hereunder to the
NYU Technology shall revert to NYU and Repare shall not be entitled to make any further use whatsoever of the NYU Technology. Notwithstanding the foregoing, if any sublicense agreements that were granted in compliance with Section 5.05 remain
in good standing as of the date of such termination, then the rights licensed herein shall be extended to such Sublicensee in the same scope as is provided in such sublicense agreement, provided that the relevant Sublicensee signs a written
agreement with NYU agreeing to be bound by the terms of this Agreement and agreeing that NYU’s only obligation hereunder shall be to maintain the effectiveness of the scope of the rights licensed hereunder to such Sublicensee.
