a person reasonably believed in the absence of gross negligence, willful misconduct or bad faith (in each case as determined by a final non appealable judgment of a court of competent jurisdiction) by the Warrant Agent to be the Chief Executive
Officer, the Chief Financial Officer, President, Secretary or Chairperson of the Board of the Company (each an authorized officer); and such certificate shall be full authorization and protection to the Warrant Agent and the Warrant Agent shall

 8 

 
this Agreement. The Warrant Agent shall not be held to have notice of any change of authority of any authorized officer, until receipt of written notice thereof from Company.”

and all loss, liability, damage, judgment, fine, penalty, claim, demand, settlement, cost or expense (including, without limitation, the reasonable fees and expenses of legal counsel) (“Losses”) that may be paid, incurred or
suffered by it, or which it may become subject, other than such Losses arising in connection with the gross negligence, bad faith or willful misconduct on the part of the Warrant Agent (which gross negligence, bad faith, or willful misconduct must
be determined by a final, non-appealable judgment of a court of competent jurisdiction), for any action taken, suffered, or omitted to be taken by the Warrant Agent arising from, directly or indirectly, the
execution, acceptance, administration, exercise and performance of its duties under this Agreement, including the costs and expenses of defending against any claim of liability arising therefrom, directly or indirectly, or enforcing its rights
hereunder. The costs and expenses incurred in enforcing this right of indemnification shall be paid by the Company. The Warrant Agent shall be liable hereunder only for its own gross negligence, bad faith or willful misconduct (which gross
negligence, bad faith or willful misconduct must be determined by a final, non-appealable judgment of a court of competent jurisdiction). Notwithstanding anything in this Agreement to the contrary, the
aggregate liability of the Warrant Agent under this Agreement will be, limited to the amount of fees paid by the Company, but not including reimbursable expenses, to the Warrant Agent during the twelve (12) months immediately preceding the
event for which recovery from the Warrant Agent is being sought. Anything to the contrary notwithstanding, in no event will the Company or the Warrant Agent be liable for special, punitive, indirect, incidental or consequential loss or damages of
any kind whatsoever (including, without limitation, lost profits), even if the Company or the Warrant Agent, as applicable, has been advised of the likelihood of or has foreseen the possibility of such loss or damages, and regardless of the form of
action. 
 The provisions under this Section 8.4 shall survive the expiration of the Warrant and the termination of this Agreement and
the resignation, replacement or removal of the Warrant Agent.” 
  

	4.24	 Acceptance of Agency. Section 8.5 is hereby amended and restated in its entirety as follows:

 “The Warrant Agent hereby accepts the agency established by this Agreement and agrees to perform the same upon the
express terms and conditions (and no implied terms and conditions) herein set forth and among other things shall account for, and pay to the Company, all monies received by the Warrant Agent for the purchase of shares of Common Stock through the
exercise of the Warrants. The Warrant Agent shall act hereunder solely as agent for the Company. The Warrant Agent shall not assume any obligations or relationship of agency or trust with any of the owners or holders of the Warrants or

  
 9 

 
Common Stock. The Warrant Agent shall not have any duty or responsibility in the case of the receipt of any written demand from any holder of Warrants or Common Stock with respect to any action
or default by the Company, including, without limiting the generality of the foregoing, any duty or responsibility to initiate or attempt to initiate any proceedings at law or otherwise or to make any demand upon the Company. The Warrant Agent shall
have no responsibility to the Company, any holders of Warrants, any holders of Common Stock or any other Person for interest or earnings on any moneys held by the Warrant Agent pursuant to this Agreement.” 

 

	4.25	 Waiver. Section 8.6 of the Existing Warrant Agreement is hereby deleted in its entirety.

  

	4.26	 The following provisions are hereby incorporated into Section 8 in the numerical order set forth below:

 8.7 Reliance on Attorneys and Agents. The Warrant Agent may consult with legal counsel selected by it (who may be
legal counsel for the Company), and the opinion or advice of such counsel shall be full and complete authorization and protection to the Warrant Agent as to any action taken or omitted by it in reliance upon such advice or opinion. The Warrant Agent
may execute and exercise any of the rights or powers hereby vested in it or perform any duty hereunder either itself or by or through its attorneys or agents, and the Warrant Agent shall not be answerable or accountable for any act, omission,
default, neglect or misconduct of any such attorneys or agents or for any loss to the Company resulting from any such act, omission, default, neglect or misconduct, absent gross negligence, willful misconduct or bad faith in the selection and
continued employment thereof (which gross negligence, willful misconduct or bad faith must be determined by a final, non-appealable judgment of a court of competent jurisdiction). 

8.8 Reliance on Agreement and Warrants. The Warrant Agent shall not be liable for or by reason of any of the statements of fact or
recitals contained in this Agreement or in the Warrants (except as to its countersignature thereof) or be required to verify the same, but all such statements and recitals are and shall be deemed to have been made by the Company only. 

8.9 No Responsibility as to Certain Matters. The Warrant Agent shall not be under any responsibility in respect of the validity of this
Agreement or the execution and delivery hereof (except the due execution hereof by the Warrant Agent) or in respect of the validity or execution of any Warrant (except its countersignature thereon); nor shall it be responsible for any breach by the
Company of any covenant or condition contained in this Agreement or in any Warrant; nor shall it be responsible for any change in the exercisability of the Warrant any adjustment required under this Agreement or responsible for the manner, method or
amount of any such adjustment or the ascertaining of the existence of facts that would require any such adjustment; nor shall it by any act hereunder be deemed to make any representation or warranty as to the authorization or reservation of any
securities to be issued pursuant to this Agreement or any Warrant or as to whether any other securities will, when so issued, be validly authorized and issued, fully paid and nonassessable. 

  
 10 

 8.10 Freedom to Trade in Company Securities. Subject to applicable laws, the Warrant
Agent and any stockholder, director, officer or employee of the Warrant Agent may buy, sell or deal in any of the Warrant or other securities of the Company or become pecuniarily interested in any transaction in which the Company may be interested,

other legal entity. 
 8.11 No Risk of Own Funds. No provision of this Agreement shall require the Warrant Agent to expend or risk its
own funds or otherwise incur any financial liability in the performance of any of its duties hereunder or in the exercise any of its rights or powers if it shall believe that repayment of such funds or adequate indemnification against such risk or
liability is not reasonably assured to it. 
 8.12 No Notice. The Warrant Agent shall not be required to take notice or be deemed to
have notice of any event or condition hereunder, including any event or condition that may require action by the Warrant Agent, unless the Warrant Agent shall be specifically notified in writing of such event or condition by the Company, and all
notices or other instruments required by this Agreement to be delivered to the Warrant Agent must, in order to be effective, be received by the Warrant Agent as specified in Section 9.2 hereof, and in the absence of such notice so delivered,
the Warrant Agent may conclusively assume no such event or condition exists. 
 8.13 Ambiguity. In the event the Warrant Agent
believes any ambiguity or uncertainty exists hereunder or in any notice, instruction, direction, request or other communication, paper or document received by the Warrant Agent hereunder, the Warrant Agent, may, in its sole discretion, refrain from
taking any action, and shall be fully protected and shall not be liable in any way to Company, the holder of any Warrant or any other person for refraining from taking such action, unless the Warrant Agent receives written instructions signed by the
Company which eliminates such ambiguity or uncertainty to the satisfaction of Warrant Agent. 
 8.14
Non-Registration. The Warrant Agent shall not be liable or responsible for any failure of the Company to comply with any of its obligations relating to any registration statement filed with the
Securities and Exchange Commission or this Agreement, including without limitation obligations under applicable regulation or law. 
 8.15
Signature Guarantee. The Warrant Agent may rely on and be fully authorized and protected in acting or failing to act upon (a) any guaranty of signature by an “eligible guarantor institution” that is a member or participant in
the Securities Transfer Agents Medallion Program or other comparable “signature guarantee program” or insurance program in addition to, or in substitution for, the foregoing; or (b) any related law, act, regulation or any
interpretation of the same. 
 8.16 Bank Accounts. All funds received by Computershare Inc. under this Agreement that are to be
distributed or applied by Computershare Inc. in the performance of services 

  
 11

its name as agent for the Company. Until paid pursuant to the terms of this Agreement, Computershare Inc. will hold the Funds through such accounts in: deposit accounts of commercial banks with Tier 1 capital exceeding $1 billion or with an
average rating above investment grade by S&P (LT Local Issuer Credit Rating), Moody’s (Long Term Rating) and Fitch Ratings, Inc. (LT Issuer Default Rating) (each as reported by Bloomberg Finance L.P.). Computershare Inc. shall have no
responsibility or liability for any diminution of the Funds that may result from any deposit made by Computershare Inc. in accordance with this paragraph, including any losses resulting from a default by any bank, financial institution or other
third party. Computershare Inc. may from time to time receive interest, dividends or other earnings in connection with such deposits. Computershare Inc. shall not be obligated to pay such interest, dividends or earnings to the Company, any holder or
any other party. 
 8.17 Force Majeure. Notwithstanding anything to the contrary contained herein, the Warrant Agent will not be
liable for any delays or failures in performance resulting from acts beyond its reasonable control including, without limitation, acts of God, epidemics, pandemics, terrorist acts, shortage of supply, disruptions in public utilities, strikes and
lock-outs, war, or civil unrest.

and data pertaining to the business of the other party, including inter alia, personal, non-public warrant holder information, which are exchanged or received pursuant to the negotiation or the carrying out of
this Agreement including the fees for services set forth in the attached schedule shall remain confidential, and shall not be voluntarily disclosed to any other person, except as may be required by law, including, without limitation, pursuant to

	4.31	 Severability. Section 9.9 is hereby amended to remove the period at the end of the first sentence

CUSIP [●] 
 Warrant
Certificate 
 This Warrant Certificate certifies that __________, or its registered assigns, is the registered
holder of __________ warrant(s) evidenced hereby (the “Warrants” and each, a “Warrant”) to purchase shares of common stock, $0.0001 par value per share (“Common Stock”), of D-Wave Quantum Inc., a Delaware corporation (the “Company”). Each Warrant entitles the holder, upon exercise during the period set forth in the Warrant Agreement referred to below, to receive
from the Company that number of fully paid and non-assessable shares of Common Stock as set forth below, at the exercise price (the “Exercise Price”) as determined pursuant to the
Warrant Agreement, payable in lawful money (or through “cashless exercise” as provided for in the Warrant Agreement) of the United States of America upon surrender of this Warrant Certificate and payment of the Exercise Price
at the office or agency of the Warrant Agent referred to below, subject to the conditions set forth herein and in the Warrant Agreement. Defined terms used in this Warrant Certificate but not defined herein shall have the meanings given to them in
the Warrant Agreement. 
 Each whole Warrant is initially exercisable for [_]2 shares
of Common Stock. If, upon the exercise of Warrants, a holder would be entitled to receive a fractional interest in a share of Common Stock, the Company will (after taking into account all Warrants exercised concurrently by such holder), upon
exercise, round down to the nearest whole number the number of shares of Common Stock to be issued to the Warrant holder. The number of shares of Common Stock issuable upon exercise of the Warrants is subject to adjustment upon the occurrence of
certain events set forth in the Warrant Agreement. 
 The initial Exercise Price for any Warrant is equal to $11.50. The Exercise Price is
subject to adjustment upon the occurrence of certain events set forth in the Warrant Agreement. 
 Subject to the conditions set forth in
the Warrant Agreement, the Warrants may be exercised only during the Exercise Period and to the extent not exercised by the end of such Exercise Period, such Warrants shall become void. 

Reference is hereby made to the further provisions of this Warrant Certificate set forth on the reverse hereof and such further provisions
shall for all purposes have the same effect as though fully set forth at this place. 
 This Warrant Certificate shall not be valid unless
countersigned by the Warrant Agent, as such term is used in the Warrant Agreement. 
 This Warrant Certificate shall be governed by and
construed in accordance with the internal laws of the State of New York, without regard to conflicts of laws principles thereof.

 [Form of Warrant Certificate] 

[Reverse] 
 The Warrants
evidenced by this Warrant Certificate are part of a duly authorized issue of Warrants entitling the holder on exercise to receive shares of Common Stock and are issued or to be issued pursuant to that certain Warrant Agreement (the
“Existing Warrant Agreement”), dated as of October 20, 2020, as amended by that certain assignment, assumption and amendment agreement (the “Amendment” and, the Existing Warrant
Agreement as amended by the Amendment, the “Warrant Agreement”) dated as of __________ , 2022, each duly executed and delivered to Computershare Inc., a Delaware corporation and its wholly-owned subsidiary, Computershare
Trust Company, N.A., a federally chartered trust company (together, the “Warrant Agent”), which Warrant Agreement is hereby incorporated by reference in and made a part of this instrument and is hereby referred to for a
description of the rights, limitation of rights, obligations, duties and immunities thereunder of the Warrant Agent, the Company and the holders (the words “holders” or “holder” meaning the Registered
Holders or Registered Holder, respectively) of the Warrants. A copy of the Warrant Agreement may be obtained by the holder hereof upon written request to the Company. Defined terms used in this Warrant Certificate but not defined herein shall have
the meanings given to them in the Warrant Agreement. 
 Warrants may be exercised at any time during the Exercise Period set forth in the
Warrant Agreement. The holder of Warrants evidenced by this Warrant Certificate may exercise them by surrendering this Warrant Certificate, with the form of election to purchase set forth hereon properly completed and executed, together with payment
of the Exercise Price as specified in the Warrant Agreement (or through “cashless exercise” as provided for in the Warrant Agreement) at the principal corporate trust office of the Warrant Agent. In the event that upon any exercise of
Warrants evidenced hereby the number of Warrants exercised shall be less than the total number of Warrants evidenced hereby, there shall be issued to the holder hereof or his, her or its assignee, a new Warrant Certificate evidencing the number of
Warrants not exercised. 
 Notwithstanding anything else in this Warrant Certificate or the Warrant Agreement, no Warrant may be exercised
unless at the time of exercise (i) a registration statement covering the shares of Common Stock to be issued upon exercise is effective under the Securities Act and (ii) a prospectus thereunder relating to the shares of Common Stock is
current, except through “cashless exercise” as provided for in the Warrant Agreement. 
 The Warrant Agreement provides that upon
the occurrence of certain events the number of shares of Common Stock issuable upon exercise of the Warrants set forth on the face hereof may, subject to certain conditions, be adjusted. If, upon exercise of a Warrant, the holder thereof would be
entitled to receive a fractional interest in a share of Common Stock, the Company shall (after taking into account all Warrants exercised concurrently by such holder), upon exercise, round down to the nearest whole number of shares of Common Stock
to be issued to the holder of the Warrant. 
 Warrant Certificates, when surrendered at the principal corporate trust office of the Warrant
Agent by the Registered Holder thereof in person or by legal representative or attorney duly authorized in writing, may be exchanged, in the manner and subject to the limitations provided in the Warrant Agreement, but without payment of any service
charge, for another Warrant Certificate or Warrant Certificates of like tenor evidencing in the aggregate a like number of Warrants. 
 Upon
due presentation for registration of transfer of this Warrant Certificate at the office of the Warrant Agent a new Warrant Certificate or Warrant Certificates of like tenor and evidencing in the aggregate a like number of Warrants shall be issued to
the transferee(s) in exchange for this Warrant Certificate, subject to the limitations provided in the Warrant Agreement, without charge except for any tax or other governmental charge imposed in connection therewith. 

The Company and the Warrant Agent may deem and treat the Registered Holder(s) hereof as the absolute owner(s) of this Warrant Certificate
(notwithstanding any notation of ownership or other writing hereon made by anyone), for the purpose of any exercise hereof, of any distribution to the holder(s) hereof, and for all other purposes, and neither the Company nor the Warrant Agent shall
be affected by any notice to the contrary. Neither the Warrants nor this Warrant Certificate entitles any holder hereof to any rights of a stockholder of the Company.
