 ATTACHMENT I 

REPARE THERAPEUTICS INC. 

2020 EQUITY INCENTIVE PLAN 

RESTRICTED SHARE UNIT AWARD AGREEMENT 

Pursuant to the Restricted Share Unit Grant Notice (the “Grant Notice”) and this Restricted Share Unit Award Agreement
(the “Agreement”), Repare Therapeutics Inc. (the “Company”) has awarded you (“Participant”) a Restricted Share Unit Award (the “Award”) pursuant to the
Company’s 2020 Equity Incentive Plan (the “Plan”) for the number of Restricted Share Units/shares indicated in the Grant Notice. Capitalized terms not explicitly defined in this Agreement or the Grant Notice shall have
the same meanings given to them in the Plan. The terms of your Award, in addition to those set forth in the Grant Notice, are as follows. 

1.    GRANT OF THE AWARD. This Award represents
the right to be issued on a future date one (1) Common Share for each Restricted Share Unit that vests on the applicable vesting date(s) (subject to any adjustment under Section 3 below) as indicated in the Grant Notice. As of the Date of
Grant, the Company will credit to a bookkeeping account maintained by the Company for your benefit (the “Account”) the number of Restricted Share Units/Common Shares subject to the Award. Notwithstanding the foregoing, the
Company reserves the right to issue you the cash equivalent of Common Shares, in part or in full satisfaction of the delivery of Common Shares in connection with the vesting of the Restricted Share Units, and, to the extent applicable, references in
this Agreement and the Grant Notice to Common Shares issuable in connection with your Restricted Share Units will include the potential issuance of its cash equivalent pursuant to such right. This Award was granted in consideration of your services
to the Company. 
 2.    VESTING. Subject to the limitations contained herein, your Award
will vest, if at all, in accordance with the vesting schedule provided in the Grant Notice. Vesting will cease upon the termination of your Continuous Service and the Restricted Share Units credited to the Account that were not vested on the date of
such termination will be forfeited at no cost to the Company and you will have no further right, title or interest in or to such Award or the Common Shares to be issued in respect of such portion of the Award. 

3.    NUMBER OF SHARES. The number of Restricted Share Units
subject to your Award may be adjusted from time to time for Capitalization Adjustments, as provided in the Plan. Any additional Restricted Share Units, shares, cash or other property that becomes subject to the Award pursuant to this Section 3,
if any, shall be subject, in a manner determined by the Board, to the same forfeiture restrictions, restrictions on transferability, and time and manner of delivery as applicable to the other Restricted Share Units and shares covered by your Award.
Notwithstanding the provisions of this Section 3, no fractional shares or rights for fractional Common Shares shall be created pursuant to this Section 3. Any fraction of a share will be rounded down to the nearest whole share. 

4.    SECURITIES LAW COMPLIANCE. You may not be
issued any Common Shares under your Award unless the Common Shares underlying the Restricted Share Units are either (i) then registered under the Securities Act, or (ii) the Company has determined that such issuance would be exempt from
the registration requirements of the Securities Act. Your Award must also comply with other applicable laws and regulations governing the Award, and you shall not receive such Common Shares if the Company determines that such receipt would not be in
material compliance with such laws and regulations. 

 5.    TRANSFER
RESTRICTIONS. Prior to the time that Common Shares have been delivered to you, you may not transfer, pledge, sell or otherwise dispose of this Award or the shares issuable in respect of your Award, except as
expressly provided in this Section 5. For example, you may not use shares that may be issued in respect of your Restricted Share Units as security for a loan. The restrictions on transfer set forth herein will lapse upon delivery to you of
shares in respect of your vested Restricted Share Units. 
 (a)    Death. Your Award is transferable by
will and by the laws of descent and distribution. At your death, vesting of your Award will cease and your executor or administrator of your estate shall be entitled to receive, on behalf of your estate, any Common Shares or other consideration that
vested but was not issued before your death. 
 (b)    Domestic Relations Orders. Upon receiving written
permission from the Board or its duly authorized designee, and provided that you and the designated transferee enter into transfer and other agreements required by the Company, you may transfer your right to receive the distribution of Common Shares
or other consideration hereunder, pursuant to a domestic relations order, marital settlement agreement or other divorce or separation instrument as permitted by applicable law that contains the information required by the Company to effectuate the
transfer. You are encouraged to discuss the proposed terms of any division of this Award with the Company General Counsel prior to finalizing the domestic relations order or marital settlement agreement to verify that you may make such transfer, and
if so, to help ensure the required information is contained within the domestic relations order or marital settlement agreement. 

6.    DATE OF ISSUANCE. 

(a)    The issuance of shares in respect of the Restricted Share Units is intended to comply with Treasury
Regulations Section 1.409A-1(b)(4) and will be construed and administered in such a manner. Subject to the satisfaction of the Withholding Obligations set forth in Section 11 of this Agreement, in
the event one or more Restricted Share Units vests, the Company shall issue to you one (1) share of Common Shares for each Restricted Share Unit that vests on the applicable vesting date(s) (subject to any adjustment under Section 3
above). Each issuance date determined by this paragraph is referred to as an “Original Issuance Date”. 

(b)    If the Original Issuance Date falls on a date that is not a business day, delivery shall instead occur on
the next following business day. In addition, if: 
 (i)    the Original Issuance Date does not occur
(1) during an “open window period” applicable to you, as determined by the Company in accordance with the Company’s then-effective policy on trading in Company securities, or (2) on a date when you are otherwise permitted to
sell Common Shares on an established stock exchange or stock market (including but not limited to under a previously established written trading plan that meets the requirements of Rule 10b5-1 under the
Exchange Act and was entered into in compliance with the Company’s policies (a “10b5-1 Arrangement), and 

(ii)    either (1) a Withholding Obligation does not apply, or (2) the Company decides, prior to the
Original Issuance Date, (A) not to satisfy the Withholding Obligation by withholding Common Shares from the shares otherwise due, on the Original Issuance Date, to you under this Award, and (B) not to permit you to enter into a “same
day sale” commitment with a broker-dealer pursuant to Section 11 of this Agreement (including but not limited to a commitment under a 10b5-1 Arrangement ) and (C) not to permit you to pay your
Withholding Obligation in cash, 

 then the shares that would otherwise be issued to you on the Original Issuance Date
will not be delivered on such Original Issuance Date and will instead be delivered on the first business day when you are not prohibited from selling shares of the Company’s Common Shares in the open public market, but in no event later than
December 31 of the calendar year in which the Original Issuance Date occurs (that is, the last day of your taxable year in which the Original Issuance Date occurs), or, if and only if permitted in a manner that complies with Treasury
Regulations Section 1.409A-1(b)(4), no later than the date that is the 15th day of the third calendar month of the applicable year following the year in which the Common Shares under this Award are no
longer subject to a “substantial risk of forfeiture” within the meaning of Treasury Regulations Section 1.409A-1(d). 

(c)    The form of delivery (e.g., a share certificate or electronic entry evidencing such shares) shall be
determined by the Company. 
 7.    DIVIDENDS. You shall receive no benefit or adjustment
to your Award with respect to any cash dividend, share dividend or other distribution that does not result from a Capitalization Adjustment; provided, however, that this sentence will not apply with respect to any Common Shares that are delivered to
you in connection with your Award after such shares have been delivered to you. 

8.    RESTRICTIVE LEGENDS. The Common Shares issued in respect of your Award
shall be endorsed with appropriate legends as determined by the Company. 
 9.    EXECUTION
OF DOCUMENTS. You hereby acknowledge and agree that the manner selected by the Company by which you indicate your consent to your Grant Notice is also deemed to be your execution of your Grant Notice and of this
Agreement. You further agree that such manner of indicating consent may be relied upon as your signature for establishing your execution of any documents to be executed in the future in connection with your Award. 

10.    AWARD NOT A SERVICE
CONTRACT. 
 (a)    Nothing in this Agreement (including, but not limited to,
the vesting of your Award or the issuance of the shares in respect of your Award), the Plan or any covenant of good faith and fair dealing that may be found implicit in this Agreement or the Plan shall: (i) confer upon you any right to continue
in the employ or service of, or affiliation with, the Company or an Affiliate; (ii) constitute any promise or commitment by the Company or an Affiliate regarding the fact or nature of future positions, future work assignments, future
compensation or any other term or condition of employment or affiliation; (iii) confer any right or benefit under this Agreement or the Plan unless such right or benefit has specifically accrued under the terms of this Agreement or Plan; or
(iv) deprive the Company of the right to terminate you at will and without regard to any future vesting opportunity that you may have. 

(b)    By accepting this Award, you acknowledge and agree that the right to continue vesting in the Award pursuant
to the vesting schedule provided in the Grant Notice may not be earned unless (in addition to any other conditions described in the Grant Notice and this Agreement) you continue as an employee, director or consultant at the will of the Company and
affiliate, as applicable (not through the act of being hired, being granted this Award or any other award or benefit) and that the Company has the right to reorganize, sell, spin-out or otherwise restructure
one or more of its businesses or Affiliates at any time or from time to time, as it deems appropriate (a “reorganization”). You acknowledge and agree that such a reorganization could result in the termination of your
Continuous Service, or the termination of Affiliate status of your employer and the loss of benefits available to you under this Agreement, including but not limited to, the termination of the right to continue vesting in the Award. You further
acknowledge and agree that this Agreement, the Plan, the transactions contemplated hereunder and the vesting schedule set forth herein or any covenant of good faith and fair dealing that 

 
may be found implicit in any of them do not constitute an express or implied promise of continued engagement as an employee or consultant for the term of this Agreement, for any period, or at
all, and shall not interfere in any way with the Company’s right to terminate your Continuous Service at any time, with or without your cause or notice, or to conduct a reorganization. 

11.    WITHHOLDING OBLIGATIONS. 

(a)    On each vesting date, and on or before the time you receive a distribution of the shares underlying your
Restricted Share Units, and at any other time as reasonably requested by the Company in accordance with applicable tax laws, you hereby authorize any required withholding from the Common Shares issuable to you and/or otherwise agree to make adequate
provision, including in cash, for any sums required to satisfy the federal, state, local and foreign tax withholding obligations of the Company or any Affiliate that arise in connection with your Award (the “Withholding
Obligation”). 
 (b)    By accepting this Award, you acknowledge and agree that the Company or any
Affiliate may, in its sole discretion, satisfy all or any portion of the Withholding Obligation relating to your Restricted Stock Units by any of the following means or by a combination of such means: (i) causing you to pay any portion of the
Withholding Obligation in cash; (ii) withholding from any compensation otherwise payable to you by the Company or any Affiliate; (iii) withholding Common Shares from the Common Shares issued or otherwise issuable to you in connection with
the Award with a fair market value (measured as of the date Common Shares are issued pursuant to Section 6) equal to the amount of such Withholding Obligation; provided, however, that the number of such Common Shares so withheld will not exceed
the amount necessary to satisfy the Withholding Obligation using the maximum statutory withholding rates for federal, state, local and foreign tax purposes, including payroll taxes, that are applicable to supplemental taxable income; and
provided, further, that to the extent necessary to qualify for an exemption from application of Section 16(b) of the Exchange Act, if applicable, such share withholding procedure will be subject to the express prior approval of the Board
or the Company’s Compensation Committee; and/or (iv) permitting or requiring you to enter into a “same day sale” commitment, if applicable, with a broker-dealer that is a member of the Financial Industry Regulatory Authority (a
“FINRA Dealer”), pursuant to this authorization and without further consent, whereby you irrevocably elect to sell a portion of the shares to be delivered in connection with your Restricted Stock Units to satisfy the
Withholding Obligation and whereby the FINRA Dealer irrevocably commits to forward the proceeds necessary to satisfy the Withholding Obligation directly to the Company and/or its Affiliates. 

(c)    Unless the Withholding Obligation is satisfied, the Company shall have no obligation to deliver to you any
Common Shares or any other consideration pursuant to this Award. 
 (d)    In the event the Withholding
Obligation arises prior to the delivery to you of Common Shares or it is determined after the delivery of Common Shares to you that the amount of the Withholding Obligation was greater than the amount withheld by the Company, you agree to indemnify
and hold the Company harmless from any failure by the Company to withhold the proper amount. 

12.    TAX CONSEQUENCES. The Company has no duty or obligation to minimize the
tax consequences to you of this Award and shall not be liable to you for any adverse tax consequences to you arising in connection with this Award. You are hereby advised to consult with your own personal tax, financial and/or legal advisors
regarding the tax consequences of this Award and by signing the Grant Notice, you have agreed that you have done so or knowingly and voluntarily declined to do so. You understand that you (and not the Company) shall be responsible for your own tax
liability that may arise as a result of this investment or the transactions contemplated by this Agreement. 

13.    LOCK-UP PERIOD.
By accepting your Award, you agree that you will not sell, dispose of, transfer, make any short sale of, grant any option for the purchase of, or enter into any hedging or similar transaction with the same economic effect as a sale with
respect to any Common Shares or other securities of the Company held by you, for a period of one hundred eighty (180) days following the effective date of a registration statement of the Company filed under the Securities Act or such longer
period as the underwriters or the Company will request to facilitate compliance with FINRA Rule 2241 or any successor or similar rules or regulation (the “Lock-Up Period”); provided,
however, that nothing contained in this section will prevent the exercise of a repurchase option, if any, in favor of the Company during the Lock-Up Period. You further agree to execute and deliver such
other agreements as may be reasonably requested by the Company or the underwriters that are consistent with the foregoing or that are necessary to give further effect thereto. In order to enforce the foregoing covenant, the Company may impose
stop-transfer instructions with respect to your Common Shares until the end of such period. You also agree that any transferee of any Common Shares (or other securities) of the Company held by you will be bound by this Section 13. The
underwriters of the Company’s shares are intended third party beneficiaries of this Section 13 and will have the right, power and authority to enforce the provisions hereof as though they were a party hereto. 

14.    UNSECURED OBLIGATION. Your Award is unfunded, and as a holder of a
vested Award, you shall be considered an unsecured creditor of the Company with respect to the Company’s obligation, if any, to issue shares or other property pursuant to this Agreement. You shall not have voting or any other rights as a
shareholder of the Company with respect to the shares to be issued pursuant to this Agreement until such shares are issued to you pursuant to Section 6 of this Agreement. Upon such issuance, you will obtain full voting and other rights as a
shareholder of the Company. Nothing contained in this Agreement, and no action taken pursuant to its provisions, shall create or be construed to create a trust of any kind or a fiduciary relationship between you and the Company or any other person.

 15.    NOTICES. Any notice or request required or permitted hereunder
shall be given in writing (including electronically) and will be deemed effectively given upon receipt or, in the case of notices delivered by mail by the Company to you, five (5) days after deposit in the mail, postage prepaid, addressed to
you at the last address you provided to the Company. The Company may, in its sole discretion, decide to deliver any documents related to participation in the Plan and this Award by electronic means or to request your consent to participate in the
Plan by electronic means. By accepting this Award, you consent to receive such documents by electronic delivery and to participate in the Plan through an on-line or electronic system established and maintained
by the Company or another third party designated by the Company. 

16.    HEADINGS. The headings of the Sections in this Agreement are inserted
for convenience only and shall not be deemed to constitute a part of this Agreement or to affect the meaning of this Agreement. 

17.    MISCELLANEOUS. 

(a)    The rights and obligations of the Company under your Award shall be transferable by the Company to any one or
more persons or entities, and all covenants and agreements hereunder shall inure to the benefit of, and be enforceable by, the Company’s successors and assigns. 

(b)    You agree upon request to execute any further documents or instruments necessary or desirable in the sole
determination of the Company to carry out the purposes or intent of your Award. 

 (c)    You acknowledge and agree that you have reviewed your
Award in its entirety, have had an opportunity to obtain the advice of counsel prior to executing and accepting your Award and fully understand all provisions of your Award. 

(d)    This Agreement shall be subject to all applicable laws, rules, and regulations, and to such approvals by any
governmental agencies or national securities exchanges as may be required. 
 (e)    All obligations of the
Company under the Plan and this Agreement shall be binding on any successor to the Company, whether the existence of such successor is the result of a direct or indirect purchase, merger, consolidation, or otherwise, of all or substantially all of
the business and/or assets of the Company. 
 (f)    You acknowledge and agree that your participation in the
Plan and acceptance of your option is entirely voluntary and not obligatory and shall not be interpreted as conferring upon you any rights or privileges other than those rights and privileges expressly provided in the Plan and this Agreement. 

18.    GOVERNING PLAN DOCUMENT. Your Award is
subject to all the provisions of the Plan, the provisions of which are hereby made a part of your Award, and is further subject to all interpretations, amendments, rules and regulations which may from time to time be promulgated and adopted pursuant
to the Plan. Your Award (and any compensation paid or shares issued under your Award) is subject to recoupment in accordance with The Dodd–Frank Wall Street Reform and Consumer Protection Act and any implementing regulations thereunder, any
clawback policy adopted by the Company and any compensation recovery policy otherwise required by applicable law. No recovery of compensation under such a clawback policy will be an event giving rise to a right to voluntarily terminate employment
upon a resignation for “good reason,” or for a “constructive termination” or any similar term under any plan of or agreement with the Company. 

19.    EFFECT ON OTHER EMPLOYEE
BENEFIT PLANS. The value of the Award subject to this Agreement shall not be included as compensation, earnings, salaries, or other similar terms used when calculating benefits under any employee benefit plan (other
than the Plan) sponsored by the Company or any Affiliate except as such plan otherwise expressly provides. The Company expressly reserves its rights to amend, modify, or terminate any or all of the employee benefit plans of the Company or any
Affiliate. 
 20.    SEVERABILITY. If all or any part of this Agreement or
the Plan is declared by any court or governmental authority to be unlawful or invalid, such unlawfulness or invalidity shall not invalidate any portion of this Agreement or the Plan not declared to be unlawful or invalid. Any Section of this
Agreement (or part of such a Section) so declared to be unlawful or invalid shall, if possible, be construed in a manner which will give effect to the terms of such Section or part of a Section to the fullest extent possible while remaining lawful
and valid. 
 21.    OTHER DOCUMENTS. You hereby acknowledge
receipt or the right to receive a document providing the information required by Rule 428(b)(1) promulgated under the Securities Act. In addition, you acknowledge receipt of the Company’s policy permitting certain individuals to sell shares
only during certain “window” periods and the Company’s insider trading policy, in effect from time to time. 

22.    AMENDMENT. This Agreement may not be modified, amended or terminated except by an
instrument in writing, signed by you and by a duly authorized representative of the Company. Notwithstanding the foregoing, this Agreement may be amended solely by the Board by a writing which specifically states that it is amending this Agreement,
so long as a copy of such amendment is delivered to 

 
you, and provided that, except as otherwise expressly provided in the Plan, no such amendment materially adversely affecting your rights hereunder may be made without your written consent.
Without limiting the foregoing, the Board reserves the right to change, by written notice to you, the provisions of this Agreement in any way it may deem necessary or advisable to carry out the purpose of the Award as a result of any change in
applicable laws or regulations or any future law, regulation, ruling, or judicial decision, provided that any such change shall be applicable only to rights relating to that portion of the Award which is then subject to restrictions as provided
herein. 
 23.    COMPLIANCE WITH
SECTION 409A OF THE CODE. This Award is intended to be exempt from the application of Section 409A of the
Code, including but not limited to by reason of complying with the “short-term deferral” rule set forth in Treasury Regulation Section 1.409A-1(b)(4) and any ambiguities herein shall be
interpreted accordingly. Notwithstanding the foregoing, if it is determined that the Award fails to satisfy the requirements of the short-term deferral rule and is otherwise not exempt from, and determined to be deferred compensation subject to
Section 409A of the Code, this Award shall comply with Section 409A to the extent necessary to avoid adverse personal tax consequences and any ambiguities herein shall be interpreted accordingly. If it is determined that the Award is
deferred compensation subject to Section 409A and you are a “Specified Employee” (within the meaning set forth in Section 409A(a)(2)(B)(i) of the Code) as of the date of your “Separation from Service” (as defined in
Section 409A), then the issuance of any shares that would otherwise be made upon the date of your Separation from Service or within the first six (6) months thereafter will not be made on the originally scheduled date(s) and will instead
be issued in a lump sum on the date that is six (6) months and one day after the date of the Separation from Service, with the balance of the shares issued thereafter in accordance with the original vesting and issuance schedule set forth
above, but if and only if such delay in the issuance of the shares is necessary to avoid the imposition of adverse taxation on you in respect of the shares under Section 409A of the Code. Each installment of shares that vests is intended to
constitute a “separate payment” for purposes of Treasury Regulation Section 1.409A-2(b)(2).

REPARE THERAPEUTICS INC. 

2020 EQUITY INCENTIVE PLAN 

RESTRICTED SHARE UNIT AWARD AGREEMENT 

Pursuant to the Restricted Share Unit Grant Notice (the “Grant Notice”) and this Restricted Share Unit Award Agreement
(the “Agreement”), Repare Therapeutics Inc. (the “Company”) has awarded you (“Participant”) a Restricted Share Unit Award (the “Award”) pursuant to the
Company’s 2020 Equity Incentive Plan (the “Plan”) for the number of Restricted Share Units/shares indicated in the Grant Notice. Capitalized terms not explicitly defined in this Agreement or the Grant Notice shall have
the same meanings given to them in the Plan. The terms of your Award, in addition to those set forth in the Grant Notice, are as follows. 

1.    GRANT OF THE AWARD. This Award represents
the right to be issued on a future date one (1) Common Share for each Restricted Share Unit that vests on the applicable vesting date(s) (subject to any adjustment under Section 3 below) as indicated in the Grant Notice. As of the Date of
Grant, the Company will credit to a bookkeeping account maintained by the Company for your benefit (the “Account”) the number of Restricted Share Units/Common Shares subject to the Award. This Award was granted in
consideration of your services to the Company. 
 2.    VESTING. Subject to the limitations
contained herein, your Award will vest, if at all, in accordance with the vesting schedule provided in the Grant Notice. Vesting will cease upon the date of termination of your Continuous Service and the Restricted Share Units credited to the
Account that were not vested on the date of such termination will be forfeited at no cost to the Company and you will have no further right, title or interest in or to such Award or the Common Shares to be issued in respect of such portion of the
Award. 
 Notwithstanding anything in the Plan, this Option Agreement or any other agreement between you and the Company or an Affiliate,
your Continuous Service will be deemed to have terminated on your last day of actual and active employment with the Company or an Affiliate, whether that day is selected by agreement with you, unilaterally by the Company or the applicable Affiliate
or otherwise and whether advance notice (pursuant to contract, civil or common law) is or is not given to you. Without limiting the generality of the foregoing, except if required by applicable employment standards legislation, no period of notice
or payment in lieu of notice that follows or is in respect of a period that follows your last day of actual and active employment shall be deemed to extend your period of employment for any purpose, including for the purpose of determining any of
your rights or entitlements under the Plan or this Agreement. Except as required by applicable employment standards legislation, you will not be entitled to damages or any compensation for any loss or in lieu of receiving any benefit under the Plan
or this Agreement due to the termination of your employment, including compensation or damages in respect of any option that does not vest or is not awarded as a result of the termination of your employment with the Company or an Affiliate. 

3.    NUMBER OF SHARES. The number of Restricted Share Units
subject to your Award may be adjusted from time to time for Capitalization Adjustments, as provided in the Plan. Any additional Restricted Share Units, shares, cash or other property that becomes subject to the Award pursuant to this Section 3,
if any, shall be subject, in a manner determined by the Board, to the same forfeiture restrictions, restrictions on transferability, and time and manner of delivery as applicable to the other Restricted Share Units and shares covered by your Award.
Notwithstanding the provisions of this Section 3, no fractional shares or rights for fractional Common Shares shall be created pursuant to this Section 3. Any fraction of a share will be rounded down to the nearest whole share. 

 4.    SECURITIES LAW
COMPLIANCE. You may not be issued any Common Shares under your Award unless the Common Shares underlying the Restricted Share Units are either (i) then registered under the Securities Act, or (ii) the
Company has determined that such issuance would be exempt from the registration requirements of the Securities Act. Your Award must also comply with other applicable laws and regulations governing the Award, and you shall not receive such Common
Shares if the Company determines that such receipt would not be in material compliance with such laws and regulations. 

5.    TRANSFER RESTRICTIONS. Prior to the time that Common
Shares have been delivered to you, you may not transfer, pledge, sell or otherwise dispose of this Award or the shares issuable in respect of your Award, except as expressly provided in this Section 5. For example, you may not use shares that
may be issued in respect of your Restricted Share Units as security for a loan. The restrictions on transfer set forth herein will lapse upon delivery to you of shares in respect of your vested Restricted Share Units. 

(a)     Death. Your Award is transferable by will and by the laws of descent and distribution. At your death,
vesting of your Award will cease and your executor or administrator of your estate shall be entitled to receive, on behalf of your estate, any Common Shares or other consideration that vested but was not issued before your death. 

(b)     Domestic Relations Orders. Upon receiving written permission from the Board or its duly authorized
designee, and provided that you and the designated transferee enter into transfer and other agreements required by the Company, you may transfer your right to receive the distribution of Common Shares or other consideration hereunder, pursuant to a
domestic relations order, marital settlement agreement or other divorce or separation instrument as permitted by applicable law that contains the information required by the Company to effectuate the transfer. You are encouraged to discuss the
proposed terms of any division of this Award with the Company General Counsel prior to finalizing the domestic relations order or marital settlement agreement to verify that you may make such transfer, and if so, to help ensure the required
information is contained within the domestic relations order or marital settlement agreement. 

6.    DATE OF ISSUANCE. 

(a)     The issuance of shares in respect of the Restricted Share Units is intended to comply with Treasury
Regulations Section 1.409A-1(b)(4) and will be construed and administered in such a manner. Subject to the satisfaction of the Withholding Obligations set forth in Section 11 of this Agreement, in
the event one or more Restricted Share Units vests, the Company shall issue to you one (1) share of Common Shares for each Restricted Share Unit that vests on the applicable vesting date(s) (subject to any adjustment under Section 3
above). Each issuance date determined by this paragraph is referred to as an “Original Issuance Date”. 
 (b)
    If the Original Issuance Date falls on a date that is not a business day, delivery shall instead occur on the next following business day. In addition, if: 

(i)     the Original Issuance Date does not occur (1) during an “open window period” applicable to
you, as determined by the Company in accordance with the Company’s then-effective policy on trading in Company securities, or (2) on a date when you are otherwise permitted to sell Common Shares on an established stock exchange or stock
market (including but not limited to under a previously established written trading plan that meets the requirements of Rule 10b5-1 under the Exchange Act and was entered into in compliance with the
Company’s policies (a “10b5-1 Arrangement), and 

 (ii)     either (1) a Withholding Obligation does not
apply, or (2) the Company decides, prior to the Original Issuance Date, (A) not to permit you to satisfy the Withholding Obligation by surrendering a portion of the Restricted Share Units, on the Original Issuance Date, and (B) not to
permit you to enter into a “same day sale” commitment with a broker-dealer pursuant to Section 11 of this Agreement (including but not limited to a commitment under a 10b5-1 Arrangement ) and
(C) not to permit you to pay your Withholding Obligation in cash, 
 then the shares that would otherwise be issued to you on
the Original Issuance Date will not be delivered on such Original Issuance Date and will instead be delivered on the first business day when you are not prohibited from selling shares of the Company’s Common Shares in the open public market,
but in no event later than December 31 of the calendar year in which the Original Issuance Date occurs (that is, the last day of your taxable year in which the Original Issuance Date occurs), or, if and only if permitted in a manner that
complies with Treasury Regulations Section 1.409A-1(b)(4), no later than the date that is the 15th day of the third calendar month of the applicable year following the year in which the Common Shares
under this Award are no longer subject to a “substantial risk of forfeiture” within the meaning of Treasury Regulations Section 1.409A-1(d). 

(c)     The form of delivery (e.g., a share certificate or electronic entry evidencing such shares) shall be
determined by the Company. 
 7.    DIVIDENDS. You shall receive no benefit or adjustment
to your Award with respect to any cash dividend, share dividend or other distribution that does not result from a Capitalization Adjustment; provided, however, that this sentence will not apply with respect to any Common Shares that are delivered to
you in connection with your Award after such shares have been delivered to you. 

8.    RESTRICTIVE LEGENDS. The Common Shares issued in respect of your Award
shall be endorsed with appropriate legends as determined by the Company. 
 9.    EXECUTION
OF DOCUMENTS. You hereby acknowledge and agree that the manner selected by the Company by which you indicate your consent to your Grant Notice is also deemed to be your execution of your Grant Notice and of this
Agreement. You further agree that such manner of indicating consent may be relied upon as your signature for establishing your execution of any documents to be executed in the future in connection with your Award. 

10.    AWARD NOT A SERVICE
CONTRACT. 
 (a)     Nothing in this Agreement (including, but not limited to,
the vesting of your Award or the issuance of the shares in respect of your Award), the Plan or any covenant of good faith and fair dealing that may be found implicit in this Agreement or the Plan shall: (i) confer upon you any right to continue
in the employ or service of, or affiliation with, the Company or an Affiliate; (ii) constitute any promise or commitment by the Company or an Affiliate regarding the fact or nature of future positions, future work assignments, future
compensation or any other term or condition of employment or affiliation; (iii) confer any right or benefit under this Agreement or the Plan unless such right or benefit has specifically accrued under the terms of this Agreement or Plan; or
(iv) deprive the Company of the right to terminate your employment without regard to any future vesting opportunity that you may have. 

(b)     By accepting this Award, you acknowledge and agree that the right to continue vesting in the Award pursuant
to the vesting schedule provided in the Grant Notice may not be earned unless (in addition to any other conditions described in the Grant Notice and this Agreement) you continue as an employee, director or consultant at the will of the Company and
affiliate, as applicable (not through the act of being hired, being granted this Award or any other award or benefit) and that the Company has 

 
the right to reorganize, sell, spin-out or otherwise restructure one or more of its businesses or Affiliates at any time or from time to time, as it deems
appropriate (a “reorganization”). You acknowledge and agree that such a reorganization could result in the termination of your Continuous Service, or the termination of Affiliate status of your employer and the loss of
benefits available to you under this Agreement, including but not limited to, the termination of the right to continue vesting in the Award. You further acknowledge and agree that this Agreement, the Plan, the transactions contemplated hereunder and
the vesting schedule set forth herein or any covenant of good faith and fair dealing that may be found implicit in any of them do not constitute an express or implied promise of continued engagement as an employee or consultant for the term of this
Agreement, for any period, or at all, and shall not interfere in any way with the Company’s right to terminate your Continuous Service at any time, with or without your cause, or to conduct a reorganization. 

11.    WITHHOLDING OBLIGATIONS. 

(a)     On each vesting date, and on or before the time you receive a distribution of the shares underlying
your Restricted Share Units, and at any other time as reasonably requested by the Company in accordance with applicable tax laws, you hereby agree to make adequate provision, including in cash, for any sums required to satisfy the federal, state,
provincial, local and foreign tax withholding obligations of the Company or any Affiliate that arise in connection with your Award (the “Withholding Obligation”). 

(b)     By accepting this Award, you acknowledge and agree that the Company or any Affiliate may, in its sole
discretion, satisfy all or any portion of the Withholding Obligation relating to your Restricted Stock Units by any of the following means or by a combination of such means: (i) causing you to pay any portion of the Withholding Obligation in
cash; (ii) withholding from any compensation otherwise payable to you by the Company or any Affiliate; (iii) permitting you to surrender to the Company for cancellation a portion of the Restricted Share Units with a fair market value
(measured as of the date Common Shares are issued pursuant to Section 6) equal to the amount of such Withholding Obligation; provided, however, that the number of such Restricted Share Units so surrendered will not exceed the amount necessary
to satisfy the Withholding Obligation using the maximum statutory withholding rates for federal, state, provincial, local and foreign tax purposes, including payroll taxes, that are applicable to supplemental taxable income; and provided,
further, that to the extent necessary to qualify for an exemption from application of Section 16(b) of the Exchange Act, if applicable, such surrender procedure will be subject to the express prior approval of the Board or the Company’s
Compensation Committee; and/or (iv) permitting or requiring you to enter into a “same day sale” commitment, if applicable, with a broker-dealer that is a member of the Financial Industry Regulatory Authority (a “FINRA
Dealer”), pursuant to this authorization and without further consent, whereby you irrevocably elect to sell a portion of the shares to be delivered in connection with your Restricted Stock Units to satisfy the Withholding Obligation and
whereby the FINRA Dealer irrevocably commits to forward the proceeds necessary to satisfy the Withholding Obligation directly to the Company and/or its Affiliates. 

(c)     Unless the Withholding Obligation is satisfied, the Company shall have no obligation to deliver to you any
Common Shares or any other consideration pursuant to this Award. 
 (d)     In the event the Withholding
Obligation arises prior to the delivery to you of Common Shares or it is determined after the delivery of Common Shares to you that the amount of the Withholding Obligation was greater than the amount withheld by the Company, you agree to indemnify
and hold the Company harmless from any failure by the Company to withhold the proper amount. 

12.    TAX CONSEQUENCES. The Company has no duty or obligation to minimize the
tax consequences to you of this Award and shall not be liable to you for any adverse tax consequences to you 

 
arising in connection with this Award. You are hereby advised to consult with your own personal tax, financial and/or legal advisors regarding the tax consequences of this Award and by signing
the Grant Notice, you have agreed that you have done so or knowingly and voluntarily declined to do so. You understand that you (and not the Company) shall be responsible for your own tax liability that may arise as a result of this investment or
the transactions contemplated by this Agreement. 

13.    LOCK-UP PERIOD.
By accepting your Award, you agree that you will not sell, dispose of, transfer, make any short sale of, grant any option for the purchase of, or enter into any hedging or similar transaction with the same economic effect as a sale with
respect to any Common Shares or other securities of the Company held by you, for a period of one hundred eighty (180) days following the effective date of a registration statement of the Company filed under the Securities Act or such longer
period as the underwriters or the Company will request to facilitate compliance with FINRA Rule 2241 or any successor or similar rules or regulation (the “Lock-Up Period”); provided,
however, that nothing contained in this section will prevent the exercise of a repurchase option, if any, in favor of the Company during the Lock-Up Period. You further agree to execute and deliver such
other agreements as may be reasonably requested by the Company or the underwriters that are consistent with the foregoing or that are necessary to give further effect thereto. In order to enforce the foregoing covenant, the Company may impose
stop-transfer instructions with respect to your Common Shares until the end of such period. You also agree that any transferee of any Common Shares (or other securities) of the Company held by you will be bound by this Section 13. The
underwriters of the Company’s shares are intended third party beneficiaries of this Section 13 and will have the right, power and authority to enforce the provisions hereof as though they were a party hereto. 

14.    UNSECURED OBLIGATION. Your Award is unfunded, and as a holder of a
vested Award, you shall be considered an unsecured creditor of the Company with respect to the Company’s obligation, if any, to issue shares or other property pursuant to this Agreement. You shall not have voting or any other rights as a
shareholder of the Company with respect to the shares to be issued pursuant to this Agreement until such shares are issued to you pursuant to Section 6 of this Agreement. Upon such issuance, you will obtain full voting and other rights as a
shareholder of the Company. Nothing contained in this Agreement, and no action taken pursuant to its provisions, shall create or be construed to create a trust of any kind or a fiduciary relationship between you and the Company or any other person.

 15.    NOTICES. Any notice or request required or permitted hereunder
shall be given in writing (including electronically) and will be deemed effectively given upon receipt or, in the case of notices delivered by mail by the Company to you, five (5) days after deposit in the mail, postage prepaid, addressed to
you at the last address you provided to the Company. The Company may, in its sole discretion, decide to deliver any documents related to participation in the Plan and this Award by electronic means or to request your consent to participate in the
Plan by electronic means. By accepting this Award, you consent to receive such documents by electronic delivery and to participate in the Plan through an on-line or electronic system established and maintained
by the Company or another third party designated by the Company. 

16.    HEADINGS. The headings of the Sections in this Agreement are inserted
for convenience only and shall not be deemed to constitute a part of this Agreement or to affect the meaning of this Agreement. 

17.    MISCELLANEOUS. 

(a)     The rights and obligations of the Company under your Award shall be transferable by the Company to any one
or more persons or entities, and all covenants and agreements hereunder shall inure to the benefit of, and be enforceable by, the Company’s successors and assigns. 

 (b)     You agree upon request to execute any further documents
or instruments necessary or desirable in the sole determination of the Company to carry out the purposes or intent of your Award. 
 (c)
    You acknowledge and agree that you have reviewed your Award in its entirety, have had an opportunity to obtain the advice of counsel prior to executing and accepting your Award and fully understand all provisions of your
Award. 
 (d)     This Agreement shall be subject to all applicable laws, rules, and regulations, and to such
approvals by any governmental agencies or national securities exchanges as may be required. 
 (e)     All
obligations of the Company under the Plan and this Agreement shall be binding on any successor to the Company, whether the existence of such successor is the result of a direct or indirect purchase, merger, consolidation, or otherwise, of all or
substantially all of the business and/or assets of the Company. 
 (f)     You acknowledge and agree that your
participation in the Plan and acceptance of your option is entirely voluntary and not obligatory and shall not be interpreted as conferring upon you any rights or privileges other than those rights and privileges expressly provided in the Plan and
this Agreement. 
 (g)     You and the Company have expressly required that this Agreement and all documents
relating thereto be drafted in the English language. Les parties aux présentes ont expressément exigé que la présente convention et tous les autres documents qui y sont afférents soient rédigés en
langue anglaise.  
 18.    GOVERNING PLAN
DOCUMENT. Your Award is subject to all the provisions of the Plan, the provisions of which are hereby made a part of your Award, and is further subject to all interpretations, amendments, rules and regulations which
may from time to time be promulgated and adopted pursuant to the Plan. Your Award (and any compensation paid or shares issued under your Award) is subject to recoupment in accordance with The Dodd–Frank Wall Street Reform and Consumer
Protection Act and any implementing regulations thereunder, any clawback policy adopted by the Company and any compensation recovery policy otherwise required by applicable law. No recovery of compensation under such a clawback policy will be an
event giving rise to a right to voluntarily terminate employment upon a resignation for “good reason,” or for a “constructive termination” or any similar term under any plan of or agreement with the Company. 

19.    EFFECT ON OTHER EMPLOYEE
BENEFIT PLANS. The value of the Award subject to this Agreement shall not be included as compensation, earnings, salaries, or other similar terms used when calculating benefits under any employee benefit plan (other
than the Plan) sponsored by the Company or any Affiliate except as such plan otherwise expressly provides. The Company expressly reserves its rights to amend, modify, or terminate any or all of the employee benefit plans of the Company or any
Affiliate. 
 20.    SEVERABILITY. If all or any part of this Agreement or
the Plan is declared by any court or governmental authority to be unlawful or invalid, such unlawfulness or invalidity shall not invalidate any portion of this Agreement or the Plan not declared to be unlawful or invalid. Any Section of this
Agreement (or part of such a Section) so declared to be unlawful or invalid shall, if possible, be construed in a manner which will give effect to the terms of such Section or part of a Section to the fullest extent possible while remaining lawful
and valid. 
 21.    OTHER DOCUMENTS. You hereby acknowledge
receipt or the right to receive a document providing the information required by Rule 428(b)(1) promulgated under the Securities Act. In addition, you acknowledge receipt of the Company’s policy permitting certain individuals to sell shares
only during certain “window” periods and the Company’s insider trading policy, in effect from time to time. 

 22.    AMENDMENT. This Agreement may not be
modified, amended or terminated except by an instrument in writing, signed by you and by a duly authorized representative of the Company. Notwithstanding the foregoing, this Agreement may be amended solely by the Board by a writing which
specifically states that it is amending this Agreement, so long as a copy of such amendment is delivered to you, and provided that, except as otherwise expressly provided in the Plan, no such amendment materially adversely affecting your rights
hereunder may be made without your written consent. Without limiting the foregoing, the Board reserves the right to change, by written notice to you, the provisions of this Agreement in any way it may deem necessary or advisable to carry out the
purpose of the Award as a result of any change in applicable laws or regulations or any future law, regulation, ruling, or judicial decision, provided that any such change shall be applicable only to rights relating to that portion of the Award
which is then subject to restrictions as provided herein. 
 23.    COMPLIANCE
WITH SECTION 409A OF THE CODE. This Award is intended to be exempt from the application of Section 409A of the Code, including but not
limited to by reason of complying with the “short-term deferral” rule set forth in Treasury Regulation Section 1.409A-1(b)(4) and any ambiguities herein shall be interpreted accordingly. Notwithstanding the foregoing, if it is determined
that the Award fails to satisfy the requirements of the short-term deferral rule and is otherwise not exempt from, and determined to be deferred compensation subject to Section 409A of the Code, this Award shall comply with Section 409A to the
extent necessary to avoid adverse personal tax consequences and any ambiguities herein shall be interpreted accordingly. If it is determined that the Award is deferred compensation subject to Section 409A and you are a “Specified Employee”
(within the meaning set forth in Section 409A(a)(2)(B)(i) of the Code) as of the date of your “Separation from Service” (as defined in Section 409A), then the issuance of any shares that would otherwise be made upon the date of your
Separation from Service or within the first six (6) months thereafter will not be made on the originally scheduled date(s) and will instead be issued in a lump sum on the date that is six (6) months and one day after the date of the Separation from
Service, with the balance of the shares issued thereafter in accordance with the original vesting and issuance schedule set forth above, but if and only if such delay in the issuance of the shares is necessary to avoid the imposition of adverse
taxation on you in respect of the shares under Section 409A of the Code. Each installment of shares that vests is intended to constitute a “separate payment” for purposes of Treasury Regulation Section 1.409A-2(b)(2).

 ATTACHMENT II 

2020 EQUITY INCENTIVE PLANEX-10.6

 Exhibit 10.6 

REPARE THERAPEUTICS INC. 

2020 EMPLOYEE SHARE PURCHASE PLAN 

ADOPTED BY THE BOARD OF DIRECTORS:
JUNE 10, 2020 
 APPROVED BY THE SHAREHOLDERS:
JUNE 10, 2020 
 IPO DATE:
[            ], 2020 
 1.    GENERAL;
PURPOSE. 
 (a)    The Plan provides a means by which Eligible Employees of the Company and
certain Designated Companies may be given an opportunity to purchase Common Shares. The Plan permits the Company to grant a series of Purchase Rights to Eligible Employees under an Employee Stock Purchase Plan. 

(b)    The Company, by means of the Plan, seeks to retain the services of such Employees, to secure and retain the
services of new Employees and to provide incentives for such persons to exert maximum efforts for the success of the Company and its Related Corporations and Affiliates. 

(c)    The Plan includes two components: a 423 Component and a Non-423
Component. The Company intends (but makes no undertaking or representation to maintain) the 423 Component to qualify as an Employee Stock Purchase Plan. The provisions of the 423 Component, accordingly, will be construed in a manner that is
consistent with the requirements of Section 423 of the Code. In addition, this Plan authorizes grants of Purchase Rights under the Non-423 Component that do not meet the requirements of an Employee Stock
Purchase Plan. Except as otherwise provided in the Plan or determined by the Board, the Non-423 Component will operate and be administered in the same manner as the 423 Component. In addition, the Company may
make separate Offerings which vary in terms (provided that such terms are not inconsistent with the provisions of the Plan or the requirements of an Employee Stock Purchase Plan), and the Company will designate which Designated Company is
participating in each separate Offering. 
 2.    ADMINISTRATION. 

(a)    The Board will administer the Plan unless and until the Board delegates administration of the Plan to a
Committee or Committees, as provided in Section 2(c). 
 (b)    The Board will have the power, subject to,
and within the limitations of, the express provisions of the Plan: 
 (i)    To determine how and when Purchase
Rights will be granted and the provisions of each Offering (which need not be identical). 
 (ii)    To designate
from time to time which Related Corporations will be eligible to participate in the Plan as Designated 423 Corporations or as Designated Non-423 Corporations, which Affiliates may be excluded from
participation in the Plan, and which Designated Companies will participate in each separate Offering (to the extent that the Company makes separate Offerings). 

(iii)    To construe and interpret the Plan and Purchase Rights, and to establish, amend and revoke rules and
regulations for its administration. The Board, in the exercise of this power, may correct any defect, omission or inconsistency in the Plan, in a manner and to the extent it deems necessary or expedient to make the Plan fully effective. 

 (iv)    To settle all controversies regarding the Plan and
Purchase Rights granted under the Plan. 
 (v)    To suspend or terminate the Plan at any time as provided in
Section 12. 
 (vi)    To amend the Plan at any time as provided in Section 12. 

(vii)    Generally, to exercise such powers and to perform such acts as it deems necessary or expedient to promote
the best interests of the Company, its Related Corporations, and Affiliates and to carry out the intent that the 423 Component be treated as an Employee Stock Purchase Plan. 

(viii)    To adopt such rules, procedures and sub-plans relating to the
operation and administration of the Plan as are necessary or appropriate under applicable local laws, regulations and procedures to permit or facilitate participation in the Plan by Employees who are foreign nationals or employed or located outside
the United States. Without limiting the generality of, but consistent with, the foregoing, the Board specifically is authorized to adopt rules, procedures, and sub-plans, which, if applicable to a Designated Non-423 Corporation, do not have to comply with the requirements of Section 423 of the Code, regarding, without limitation, eligibility to participate in the Plan, the definition of eligible
“earnings,” handling and making of Contributions, establishment of bank or trust accounts to hold Contributions, payment of interest, conversion of local currency, obligations to pay payroll tax, determination of beneficiary designation
requirements, withholding procedures and handling of share issuances, any of which may vary according to applicable requirements. 

(c)    The Board may delegate some or all of the administration of the Plan to a Committee or Committees. If
administration is delegated to a Committee, the Committee will have, in connection with the administration of the Plan, the powers theretofore possessed by the Board that have been delegated to the Committee, including the power to delegate to a
subcommittee any of the administrative powers the Committee is authorized to exercise (and references in this Plan and in any applicable Offering Document to the Board will thereafter be to the Committee or subcommittee), subject, however, to such
resolutions, not inconsistent with the provisions of the Plan, as may be adopted from time to time by the Board. Further, to the extent not prohibited by applicable law, the Board or Committee may, from time to time, delegate some or all of its
authority under the Plan to other persons or groups of persons as it deems necessary, appropriate, or advisable under conditions or limitations that it may set at or after the time of the delegation. The Board may retain the authority to
concurrently administer the Plan with the Committee and may, at any time, revest in the Board some or all of the powers previously delegated. Whether or not the Board has delegated administration of the Plan to a Committee, the Board will have the
final power to determine all questions of policy and expediency that may arise in the administration of the Plan. 

(d)    All determinations, interpretations and constructions made by the Board in good faith will not be subject to
review by any person and will be final, binding and conclusive on all persons. 
 3.    COMMON SHARES
SUBJECT TO THE PLAN. 
 (a)    Subject to the
provisions of Section 11(a) relating to Capitalization Adjustments and the following sentence regarding the Evergreen Increase, the initial number of Common Shares that may be issued under the Plan shall equal 327,000 shares (the
“Share Reserve”). In addition, the Share Reserve will automatically increase on January 1st of each year for a period of up to ten (10) years, commencing on
January 1, 2021 and ending on (and including) January 1, 2030 (each, an “Evergreen Date”), in an amount equal to the lesser of (i) one percent (1%) of the total number of Capital Shares outstanding on
December 31st immediately preceding the applicable Evergreen Date, and (ii) 3,300,000 shares (the “Evergreen Increase”). Notwithstanding the foregoing, the Board may act
prior to the Evergreen Date of a given year 

  
 2 

 
to provide that there will be no Evergreen Increase for such year or that the Evergreen Increase for such year will be a lesser number of Common Shares than would otherwise occur pursuant to the
preceding sentence. For the avoidance of doubt, up to the maximum number of Common Shares reserved under this Section 3(a) may be used to satisfy purchases of Common Shares under the 423 Component and any remaining portion of such maximum
number of shares may be used to satisfy purchases of Common Shares under the Non-423 Component. 

(b)    If any Purchase Right granted under the Plan terminates without having been exercised in full, the Common
Shares not purchased under such Purchase Right will again become available for issuance under the Plan. 

(c)    The shares purchasable under the Plan will be shares of authorized but unissued Common Shares. 

4.    GRANT OF PURCHASE RIGHTS; OFFERING. 

(a)    The Board may from time to time grant or provide for the grant of Purchase Rights to Eligible Employees under
an Offering (consisting of one or more Purchase Periods) on an Offering Date or Offering Dates selected by the Board. Each Offering will be in such form and will contain such terms and conditions as the Board will deem appropriate, and, with respect
to the 423 Component, will comply with the requirement of Section 423(b)(5) of the Code that all Employees granted Purchase Rights will have the same rights and privileges. The terms and conditions of an Offering shall be incorporated by
reference into the Plan and treated as part of the Plan. The provisions of separate Offerings need not be identical, but each Offering will include (through incorporation of the provisions of this Plan by reference in the Offering Document or
otherwise) the period during which the Offering will be effective, which period will not exceed 27 months beginning with the Offering Date, and the substance of the provisions contained in Sections 5 through 8, inclusive. 

(b)    If a Participant has more than one Purchase Right outstanding under the Plan, unless he or she otherwise
indicates in forms delivered to the Company or a third party designated by the Company (each, a “Company Designee”): (i) each form will apply to all of his or her Purchase Rights under the Plan, and (ii) a Purchase Right
with a lower exercise price (or an earlier-granted Purchase Right, if different Purchase Rights have identical exercise prices) will be exercised to the fullest possible extent before a Purchase Right with a higher exercise price (or a later-granted
Purchase Right if different Purchase Rights have identical exercise prices) will be exercised. 
 (c)    The
Board will have the discretion to structure an Offering so that if the Fair Market Value of a Common Share on the first Trading Day of a new Purchase Period within that Offering is less than or equal to the Fair Market Value of a Common Share on the
Offering Date for that Offering, then (i) that Offering will terminate immediately as of that first Trading Day, and (ii) the Participants in such terminated Offering will be automatically enrolled in a new Offering beginning on the first
Trading Day of such new Purchase Period. 
 5.    ELIGIBILITY. 

(a)    Purchase Rights may be granted only to Employees of the Company or, as the Board may designate in accordance
with Section 2(b), to Employees of a Related Corporation or an Affiliate. Except as provided in Section 5(b) or as required by applicable law, an Employee will not be eligible to be granted Purchase Rights unless, on the Offering Date, the
Employee has been in the employ of the Company, a Related Corporation or an Affiliate, as the case may be, for such continuous period preceding such Offering Date as the Board may require, but in no event will the required period of continuous
employment be equal 

  
 3 

 
to or greater than two years. For clarity, except as may be required by applicable employment standards legislation, no period of notice that was given or that ought to have been given shall
constitute employment for the purposes of determining any entitlements under the Plan. In addition, the Board may provide that no Employee will be eligible to be granted Purchase Rights under the Plan unless, on the Offering Date, such
Employee’s customary employment with the Company, the Related Corporation, or the Affiliate, as applicable, is more than 20 hours per week and more than five months per calendar year or such other criteria as the Board may determine consistent
with Section 423 of the Code with respect to the 423 Component and applicable laws. 
 (b)    The Board may
provide that each person who, during the course of an Offering, first becomes an Eligible Employee will, on a date or dates specified in the Offering which coincides with the day on which such person becomes an Eligible Employee or which occurs
thereafter, receive a Purchase Right under that Offering, which Purchase Right will thereafter be deemed to be a part of that Offering. Such Purchase Right will have the same characteristics as any Purchase Rights originally granted under that
Offering, as described herein, except that: 
 (i)    the date on which such Purchase Right is granted will be
the “Offering Date” of such Purchase Right for all purposes, including determination of the exercise price of such Purchase Right; 

(ii)    the period of the Offering with respect to such Purchase Right will begin on its Offering Date and end
coincident with the end of such Offering; and 
 (iii)    the Board may provide that if such person first becomes
an Eligible Employee within a specified period of time before the end of the Offering, he or she will not receive any Purchase Right under that Offering. 

(c)    No Employee will be eligible for the grant of any Purchase Rights if, immediately after any such Purchase
Rights are granted, such Employee owns shares possessing five percent or more of the total combined voting power or value of all classes of shares of the Company or of any Related Corporation. For purposes of this Section 5(c), the rules of
Section 424(d) of the Code will apply in determining the share ownership of any Employee, and shares which such Employee may purchase under all outstanding Purchase Rights and options will be treated as shares owned by such Employee. 

(d)    As specified by Section 423(b)(8) of the Code, an Eligible Employee may be granted Purchase Rights only
if such Purchase Rights, together with any other rights granted under all Employee Stock Purchase Plans of the Company and any Related Corporations or Affiliates, do not permit such Eligible Employee’s rights to purchase shares of the Company
or any Related Corporation or Affiliates to accrue at a rate which, when aggregated, exceeds US$25,000 of Fair Market Value of such shares (determined at the time such rights are granted, and which, with respect to the Plan, will be determined as of
their respective Offering Dates) for each calendar year in which such rights are outstanding at any time, subject to compliance with applicable laws. 

(e)    Officers of the Company and any Designated Company, if they are otherwise Eligible Employees, will be
eligible to participate in Offerings under the Plan. Notwithstanding the foregoing, the Board may provide in an Offering that Employees who are highly compensated Employees within the meaning of Section 423(b)(4)(D) of the Code will not be
eligible to participate. 
 (f)    Notwithstanding anything in this Section 5 to the contrary, in the case
of an Offering under the Non-423 Component, an Eligible Employee (or group of Eligible Employees) may be excluded from participation in the Plan or an Offering if the Board has determined, in its sole
discretion, that participation of such Eligible Employee(s) is not advisable or practical for any reason. 

  
 4 

 6.    PURCHASE RIGHTS; PURCHASE
PRICE. 
 (a)    On each Offering Date, each Eligible Employee, pursuant to an Offering made
under the Plan, will be granted a Purchase Right to purchase up to that number of Common Shares (rounded down to the nearest whole share) purchasable either with a percentage or with a maximum dollar amount, as designated by the Board, but in either
case not exceeding 15% of such Employee’s earnings (as defined by the Board in each Offering) during the period that begins on the Offering Date (or such later date as the Board determines for a particular Offering) and ends on the date stated
in the Offering, which date will be no later than the end of the Offering. 
 (b)    The Board will establish one
or more Purchase Dates during an Offering on which Purchase Rights granted for that Offering will be exercised and Common Shares will be purchased in accordance with such Offering. 

(c)    In connection with each Offering made under the Plan, the Board may specify (i) a maximum number of
Common Shares that may be purchased by any Participant on any Purchase Date during such Offering, (ii) a maximum aggregate number of Common Shares that may be purchased by all Participants pursuant to such Offering and/or (iii) a maximum
aggregate number of Common Shares that may be purchased by all Participants on any Purchase Date under the Offering. If the aggregate purchase of Common Shares issuable upon exercise of Purchase Rights granted under the Offering would exceed any
such maximum aggregate number, then, in the absence of any Board action otherwise, a pro rata (based on each Participant’s accumulated Contributions) allocation of Common Shares (rounded down to the nearest whole share) available will be made
in as nearly a uniform manner as will be practicable and equitable. 
 (d)    The purchase price of Common Shares
acquired pursuant to Purchase Rights will be not less than the lesser of: 
 (i)    an amount equal to 85% of the
Fair Market Value of the Common Shares on the Offering Date; or 
 (ii)    an amount equal to 85% of the Fair
Market Value of the Common Shares on the applicable Purchase Date. 
 7.    PARTICIPATION; WITHDRAWAL;
TERMINATION. 
 (a)    An Eligible Employee may elect to authorize payroll deductions as the
means of making Contributions by completing and delivering to the Company or Company Designee, within the time specified in the Offering, an enrollment form provided by the Company or Company Designee. The enrollment form will specify the amount of
Contributions not to exceed the maximum amount specified by the Board. Each Participant’s Contributions will be credited to a bookkeeping account for such Participant under the Plan and will be deposited with the general funds of the Company
except where applicable laws or regulations require that Contributions be deposited with a Company Designee or otherwise segregated. If permitted in the Offering, a Participant may begin such Contributions with the first payroll occurring on or
after the Offering Date (or, in the case of a payroll date that occurs after the end of the prior Offering but before the Offering Date of the next new Offering, Contributions from such payroll will be included in the new Offering). If permitted in
the Offering, a Participant may thereafter reduce (including to zero) or increase his or her Contributions. If required under applicable laws or regulations or if specifically provided in the Offering, in addition to or instead of making
Contributions by payroll deductions, a Participant may make Contributions through a payment by cash, check, or wire transfer prior to a Purchase Date, in a manner directed by the Company or a Company Designee. 

  
 5 

 (b)    During an Offering, a Participant may cease making
Contributions and withdraw from the Offering by delivering to the Company or a Company Designee a withdrawal form provided by the Company. The Company may impose a deadline before a Purchase Date for withdrawing. Upon such withdrawal, such
Participant’s Purchase Right in that Offering will immediately terminate and the Company will distribute as soon as practicable to such Participant all of his or her accumulated but unused Contributions and such Participant’s Purchase
Right in that Offering shall thereupon terminate. A Participant’s withdrawal from that Offering will have no effect upon his or her eligibility to participate in any other Offerings under the Plan, but such Participant will be required to
deliver a new enrollment form to participate in subsequent Offerings. 
 (c)    Unless otherwise required by
applicable law, Purchase Rights granted pursuant to any Offering under the Plan will terminate immediately if the Participant either (i) is no longer an Employee for any reason or for no reason or (ii) is otherwise no longer eligible to
participate. In this regard, unless otherwise determined by the Board, a Participant whose employment transfers or whose employment terminates with an immediate rehire (with no break in service) by or between the Company and a Designated Company
will not be treated as having terminated employment for purposes of participating in the Plan or an Offering; however, if a Participant transfers from an Offering under the 423 Component to an Offering under the
Non-423 Component, the exercise of the Participant’s Purchase Right will be qualified under the 423 Component only to the extent such exercise complies with Section 423 of the Code. If a Participant
transfers from an Offering under the Non-423 Component to an Offering under the 423 Component, the exercise of the Purchase Right will remain non-qualified under the Non-423 Component. In the event that a Participant’s Purchase Right is terminated under the Plan, the Company will distribute as soon as practicable to such individual all of his or her accumulated but unused
Contributions. 
 (d)    During a Participant’s lifetime, Purchase Rights will be exercisable only by such
Participant. Purchase Rights are not transferable by a Participant, except by will, by the laws of descent and distribution, or, if permitted by the Company, by a beneficiary designation as described in Section 10. 

(e)    Unless otherwise specified in the Offering or required by applicable law, the Company will have no
obligation to pay interest on Contributions. 
 8.    EXERCISE OF PURCHASE
RIGHTS. 
 (a)    On each Purchase Date, each Participant’s accumulated Contributions will
be applied to the purchase of Common Shares (rounded down to the nearest whole share), up to the maximum number of Common Shares permitted by the Plan and the applicable Offering, at the purchase price specified in the Offering. No fractional shares
will be issued unless specifically provided for in the Offering. 
 (b)    Unless otherwise provided in the
Offering, if any amount of accumulated Contributions remains in a Participant’s account after the purchase of Common Shares and such remaining amount is less than the amount required to purchase one Common Share on the final Purchase Date of an
Offering, then such remaining amount will be held in such Participant’s account for the purchase of Common Shares under the next Offering under the Plan, unless such Participant withdraws from or is not eligible to participate in such Offering,
in which case such amount will be distributed to such Participant after the final Purchase Date, without interest, unless the payment of interest is required by applicable laws. If the amount of Contributions remaining in a Participant’s
account after the purchase of Common Shares is at least equal to the amount required to purchase one whole Common Share on the final Purchase Date of an Offering, then such remaining amount will not roll over to the next Offering and will instead be
distributed in full to such Participant after the final Purchase Date of such Offering without interest, unless the payment of interest is required by applicable laws. 

  
 6 

 (c)    No Purchase Rights may be exercised to any extent unless
the Common Shares to be issued upon such exercise under the Plan are covered by an effective registration statement pursuant to the Securities Act and the Plan is in material compliance with all applicable U.S. federal and state, foreign and other
securities, exchange control and other laws applicable to the Plan. If on a Purchase Date the Common Shares are not so registered or the Plan is not in such compliance, no Purchase Rights will be exercised on such Purchase Date, and the Purchase
Date will be delayed until the Common Shares are subject to such an effective registration statement and the Plan is in material compliance, except that the Purchase Date will not be delayed more than 12 months and the Purchase Date will in no event
be more than 27 months from the Offering Date. If, on the Purchase Date, as delayed to the maximum extent permissible, the Common Shares are not registered and the Plan is not in material compliance with all applicable laws or regulations, as
determined by the Company in its sole discretion, no Purchase Rights will be exercised and all accumulated but unused Contributions will be distributed as soon as practicable to the Participants without interest, unless the payment of interest is
required by applicable laws. 
 9.    COVENANTS OF THE COMPANY. 

The Company will seek to obtain from each U.S. federal or state, foreign or other regulatory commission or agency having jurisdiction over the
Plan such authority as may be required to grant Purchase Rights and issue and sell Common Shares thereunder unless the Company determines, in its sole discretion, that doing so would cause the Company to incur costs that are unreasonable. If, after
commercially reasonable efforts, the Company is unable to obtain the authority that counsel for the Company deems necessary for the grant of Purchase Rights or the lawful issuance and sale of Common Shares under the Plan, and at a commercially
reasonable cost, the Company will be relieved from any liability for failure to grant Purchase Rights and/or to issue and sell Common Shares upon exercise of such Purchase Rights. 

10.    DESIGNATION OF BENEFICIARY. 

(a)    The Company may, but is not obligated to, permit a Participant to submit a form designating a beneficiary who
will receive any Common Shares and/or Contributions from the Participant’s account under the Plan if the Participant dies before such shares and/or Contributions are delivered to the Participant. The Company may, but is not obligated to, permit
the Participant to change such designation of beneficiary. Any such designation and/or change must be on a form approved by the Company or as approved by the Company for use by a Company Designee. 

(b)    If a Participant dies, in the absence of a valid beneficiary designation, the Company will deliver any
Common Shares and/or Contributions to the executor or administrator of the estate of the Participant. If no executor or administrator has been appointed (to the knowledge of the Company), the Company, in its sole discretion, may deliver such Common
Shares and/or Contributions, without interest, unless the payment of interest is required by applicable laws, to the Participant’s spouse, dependents or relatives, or if no spouse, dependent or relative is known to the Company, then to such
other person as the Company may designate. 
 11.    ADJUSTMENTS UPON CHANGES
IN COMMON SHARES; CORPORATE TRANSACTIONS. 

(a)    In the event of a Capitalization Adjustment, the Board will appropriately and proportionately adjust:
(i) the class(es) and maximum number of securities subject to the Plan pursuant to Section 3(a), (ii) the class(es) and maximum number of securities by which the share reserve is to increase automatically each year pursuant to
Section 3(a), (iii) the class(es) and number of securities subject to, and the purchase price applicable to outstanding Offerings and Purchase Rights, and (iv) the class(es) and number of securities that are the subject of the purchase
limits under each ongoing Offering. The Board will make these adjustments, and its determination will be final, binding and conclusive. 

  
 7 

 (b)    In the event of a Corporate Transaction, then:
(i) any surviving corporation or acquiring corporation (or the surviving or acquiring corporation’s parent company) may assume or continue outstanding Purchase Rights or may substitute similar rights (including a right to acquire the same
consideration paid to the shareholders in the Corporate Transaction) for outstanding Purchase Rights, or (ii) if any surviving or acquiring corporation (or its parent company) does not assume or continue such Purchase Rights or does not
substitute similar rights for such Purchase Rights, then the Participants’ accumulated Contributions will be used to purchase Common Shares (rounded down to the nearest whole share) within ten business days prior to the Corporate Transaction
under the outstanding Purchase Rights, and the Purchase Rights will terminate immediately after such purchase. 

12.    AMENDMENT, TERMINATION OR SUSPENSION OF
THE PLAN. 
 (a)    The Board may amend the Plan at any time in any respect the
Board deems necessary or advisable. However, except as provided in Section 11(a) relating to Capitalization Adjustments, shareholder approval will be required for any amendment of the Plan for which shareholder approval is required by
applicable laws, regulations or listing requirements, including any amendment that either (i) materially increases the number of Common Shares available for issuance under the Plan, (ii) materially expands the class of individuals eligible
to become Participants and receive Purchase Rights, (iii) materially increases the benefits accruing to Participants under the Plan or materially reduces the price at which Common Shares may be purchased under the Plan, (iv) materially
extends the term of the Plan, or (v) expands the types of awards available for issuance under the Plan, but in each of (i) through (v) above only to the extent shareholder approval is required by applicable laws, regulations, or listing
requirements. 
 (b)    The Board may suspend or terminate the Plan at any time. No Purchase Rights may be
granted under the Plan while the Plan is suspended or after it is terminated. 
 (c)    Any benefits, privileges,
entitlements and obligations under any outstanding Purchase Rights granted before an amendment, suspension or termination of the Plan will not be materially impaired by any such amendment, suspension or termination except (i) with the consent
of the person to whom such Purchase Rights were granted, (ii) as necessary to comply with any laws, listing requirements, or governmental regulations (including, without limitation, the provisions of Section 423 of the Code and the
regulations and other interpretive guidance issued thereunder relating to Employee Stock Purchase Plans) including without limitation any such regulations or other guidance that may be issued or amended after the Effective Date, or (iii) as
necessary to obtain or maintain any special tax, listing, or regulatory treatment. To be clear, the Board may amend outstanding Purchase Rights without a Participant’s consent if such amendment is necessary to ensure that the Purchase Right
and/or the 423 Component complies with the requirements of Section 423 of the Code, or other applicable laws, listing requirements, or governmental regulations. 

Notwithstanding anything in the Plan or any Offering Document to the contrary, the Board will be entitled to: (i) establish the exchange
ratio applicable to amounts withheld in a currency other than U.S. dollars; (ii) permit Contributions in excess of the amount designated by a Participant in order to adjust for mistakes in the Company’s processing of properly completed
Contribution elections; (iii) establish reasonable waiting and adjustment periods and/or accounting and crediting procedures to ensure that amounts applied toward the purchase of Common Shares for each Participant properly correspond with
amounts withheld from the Participant’s Contributions; (iv) amend any outstanding Purchase Rights or clarify any ambiguities regarding the terms of any Offering to enable the Purchase Rights to qualify under and/or comply with
Section 423 of the Code; and (v) establish other limitations or procedures as the Board determines in its sole discretion advisable that are consistent with the Plan. The actions of the Board pursuant to this paragraph will not be
considered to alter or impair any Purchase Rights granted under an Offering as they are part of the initial terms of each Offering and the Purchase Rights granted under each Offering. 

  
 8 

 13.    SECTION 409A OF THE
CODE; TAX QUALIFICATION. 
 (a)    Purchase Rights granted under
the 423 Component are intended to be exempt from the application of Section 409A of the Code under U.S. Treasury Regulation Section 1.409A-1(b)(5)(ii). Purchase Rights granted under the Non-423 Component to U.S. taxpayers are intended to be exempt from the application of Section 409A of the Code under the short-term deferral exception and any ambiguities will be construed and interpreted in
accordance with such intent. Subject to Section 13(b) below, Purchase Rights granted to U.S. taxpayers under the Non-423 Component will be subject to such terms and conditions that will permit such
Purchase Rights to satisfy the requirements of the short-term deferral exception available under Section 409A of the Code, including the requirement that the shares subject to a Purchase Right be delivered within the short-term deferral
period. Subject to Section 13(b) below, in the case of a Participant who would otherwise be subject to Section 409A of the Code, to the extent the Board determines that a Purchase Right or the exercise, payment, settlement or deferral
thereof is subject to Section 409A of the Code, the Purchase Right will be granted, exercised, paid, settled or deferred in a manner that will comply with Section 409A of the Code, including U.S. Department of Treasury regulations and
other interpretive guidance issued thereunder, including, without limitation, any such regulations or other guidance that may be issued after the adoption of the Plan. Notwithstanding the foregoing, the Company will have no liability to a
Participant or any other party if the Purchase Right that is intended to be exempt from or compliant with Section 409A of the Code is not so exempt or compliant or for any action taken by the Board with respect thereto. 

(b)    Although the Company may endeavor to (i) qualify a Purchase Right for special tax treatment under the
laws of the United States or jurisdictions outside of the United States or (ii) avoid adverse tax treatment (e.g., under Section 409A of the Code), the Company makes no representation to that effect and expressly disavows any
covenant to maintain special or to avoid unfavorable tax treatment, notwithstanding anything to the contrary in this Plan, including Section 13(a) above. The Company will be unconstrained in its corporate activities without regard to the
potential negative tax impact on Participants under the Plan. 
 14.    TAX WITHHOLDING 

The Participant will make adequate provision to satisfy the Tax-Related Items withholding obligations,
if any, of the Company and/or the applicable Designated Company which arise with respect to Participant’s participation in the Plan or upon the disposition of the Common Shares. The Company and/or the Designated Company may, but will not be
obligated to, withhold from the Participant’s compensation or any other payments due the Participant the amount necessary to meet such withholding obligations or withhold from the proceeds of the sale of Common Shares or any other method of
withholding that the Company and/or the Designated Company deems appropriate. The Company and/or the Designated Company will have the right to take such other action as may be necessary in the opinion of the Company or a Designated Company to
satisfy withholding and/or reporting obligations for such Tax-Related Items. 

15.    EFFECTIVE DATE OF PLAN. 

The Plan will become effective immediately prior to and contingent upon the IPO Date. No Purchase Rights will be exercised unless and until the
Plan has been approved by the shareholders of the Company, which approval must be within 12 months before or after the date the Plan is adopted (or if required under Section 12(a) above, materially amended) by the Board. 

  
 9 

 16.    MISCELLANEOUS PROVISIONS. 

(a)    Proceeds from the sale of Common Shares pursuant to Purchase Rights will constitute general funds of the
Company. 
 (b)    A Participant will not be deemed to be the holder of, or to have any of the rights of a holder
with respect to, Common Shares subject to Purchase Rights unless and until the Participant’s Common Shares acquired upon exercise of Purchase Rights are recorded in the books of the Company (or its transfer agent). 

(c)    The Plan and Offering do not constitute an employment contract. Nothing in the Plan or in the Offering will
in any way alter the at-will nature of a Participant’s employment, if applicable, or be deemed to create in any way whatsoever any obligation on the part of any Participant to continue in the employ of
the Company, a Related Corporation, or an Affiliate, or on the part of the Company, a Related Corporation or an Affiliate to continue the employment of a Participant. For clarity, participation in the Plan or the Offering will not interfere with the
right of the Company, a Related Corporation, or an Affiliate to terminate a Participant’s employment for any reason, in accordance with applicable law. Further, if a Participant ceases to be in the employ of the Company, a Related Corporation,
or an Affiliate, such Participant will not be entitled to any compensation for any loss of any right or benefit or prospective right or benefit pursuant to or in connection with the Plan whether such compensation is claimed by way of damages for
wrongful dismissal or other breach of contract or by way of compensation for loss of employment or office or otherwise howsoever. 

(d)    The laws of the province of Quebec and the laws of Canada applicable therein will govern all questions
concerning the construction, validity and interpretation of this Plan without resort to such province’s conflicts of laws rules. 

(e)    If any particular provision of the Plan is found to be invalid or otherwise unenforceable, such provision
will not affect the other provisions of the Plan, but the Plan will be construed in all respects as if such invalid provision were omitted. 

(f)    The Company’s insider trading policy as in effect from time to time may be applicable to an
Employee’s rights under the Plan. Notwithstanding any Plan provision to the contrary, no Employee shall, while in possession of material undisclosed information, elect to enroll or elect to increase, decrease or cease Contributions. The Board
may require an Employee to acknowledge that such election is being made in compliance with the Company’s insider trading policy. 

(g)    If any provision of the Plan does not comply with applicable law or regulations, such provision shall be
construed in such a manner as to comply with applicable law or regulations.
