COVENANTS OF D-WAVE QUANTUM AND EXCHANGECO 

2.1 Covenants Regarding Exchangeable Shares. So long as any Exchangeable Shares not owned by
D-Wave Quantum or its affiliates are outstanding, D-Wave Quantum shall: 
  

	 	(a)	 not take any action that will result in the declaration or payment of any dividend or make any other
distribution on the D-Wave Quantum Shares unless: 

  

	 	(i)	 ExchangeCo shall (A) simultaneously declare or pay, as the case may be, an equivalent dividend or other
distribution economically equivalent thereto (as determined in accordance with the Exchangeable Share Provisions) on the Exchangeable Shares (an “Equivalent Dividend”), (B) in the case of a cash dividend or other distribution,
receive sufficient money or other assets from D-Wave Quantum (through any intermediary entities) to enable the due declaration and the due and punctual payment, in accordance with applicable law and the
Exchangeable Share Provisions, of any such Equivalent Dividend, and (C) in the case of a dividend or other distribution that is a stock or share dividend or a distribution of stock or shares, have sufficient authorized but unissued securities
available to enable the due declaration and the due and punctual payment, in accordance with applicable law and the Exchangeable Share Provisions, of any such Equivalent Dividend; provided however, for the avoidance of doubt, that in no event may
ExchangeCo elect to effect a dividend or other distribution that is a stock or share dividend or a distribution of stock or shares in the form of cash or property other than stock or shares; or 

 

	 	(ii)	 if the board of directors of ExchangeCo so chooses, in its sole discretion, as an alternative to taking any of
the actions described in (i), ExchangeCo shall adjust the Exchangeable Share Exchange Ratio in accordance with the Exchangeable Share Provisions, provided however that the Exchangeable Share Exchange Ratio shall only be so adjusted to the extent
that the board of directors of ExchangeCo determines in good faith and in its sole discretion that ExchangeCo would be liable for any unrecoverable tax as a result of taking any of the actions described in (i), and determines to adjust the
Exchangeable Share Exchange Ratio in lieu of taking any such action; 

  

	 	(b)	 advise ExchangeCo sufficiently in advance of the declaration by D-Wave
Quantum of any dividend or other distribution on the D-Wave Quantum Shares and take all such other actions as are reasonably necessary or desirable, in co-operation with
ExchangeCo, to ensure that the respective declaration date, 

	 	
record date and payment date for an Equivalent Dividend shall be the same as the declaration date, record date and payment date for the corresponding dividend or other distribution on the D-Wave Quantum Shares; 

  

	 	(c)	 ensure that the record date for any dividend or other distribution declared on the D-Wave Quantum Shares is not less than 10 Business Days after the declaration date of such dividend or declaration; 

  

	 	(d)	 take all such actions and do all such things as are reasonably necessary or desirable to enable and permit
ExchangeCo, in accordance with applicable law, to pay and otherwise perform its obligations with respect to the satisfaction of the Liquidation Amount, the Retraction Price or the Redemption Price in respect of each issued and outstanding
Exchangeable Share upon the liquidation, dissolution or winding-up of ExchangeCo, whether voluntary or involuntary, or any other distribution of the assets of ExchangeCo among its shareholders for the purpose
of winding up its affairs, the delivery of a Retraction Request by a holder of Exchangeable Shares or a redemption of Exchangeable Shares by ExchangeCo, as the case may be, including, without limitation, all such actions and all such things as are
necessary or desirable to enable and permit ExchangeCo to deliver or cause to be delivered D-Wave Quantum Shares or other property to the holders of Exchangeable Shares in accordance with the provisions of
Sections 27.5, 27.6 or 27.7, as the case may be, of the Exchangeable Share Provisions; 

  

	 	(e)	 take all such actions and do all such things as are reasonably necessary or desirable to enable and permit the
Trustee, in accordance with applicable law, to perform its obligations under the Voting and Exchange Trust Agreement, including, without limitation, all such actions and all such things as are reasonably necessary or desirable to enable and permit
the Trustee in its capacity as trustee under the Voting and Exchange Trust Agreement to exercise such number of votes in respect of a D-Wave Quantum Meeting (as such term is defined in the Voting and Exchange
Trust Agreement) as is equal to the aggregate number of Exchangeable Shares outstanding at the relevant time (other than those held by D-Wave Quantum and its affiliates) multiplied by the Exchangeable Share
Exchange Ratio; 

  

	 	(f)	 take all such actions and do all such things as are reasonably necessary or desirable to enable and permit D-Wave Quantum or CallCo, as the case may be, in accordance with applicable law, to perform its obligations arising upon the exercise by it of the Liquidation Call Right, the Retraction Call Right, the Change of Law
Call Right or the Redemption Call Right, including, without limitation, all such actions and all such things as are necessary or desirable to enable and permit D-Wave Quantum or CallCo, as the case may be, to
deliver or cause to be delivered D-Wave Quantum Shares or other property to the holders of Exchangeable Shares in accordance with the provisions of the Liquidation Call Right, the Retraction Call Right, the
Change of Law Call Right or the Redemption Call Right, as the case may be; 

  

	 	(g)	 take all such actions and do all such things as are reasonably necessary or desirable to enable and permit D-Wave Quantum, in accordance with applicable law, to perform its obligations in connection with a Retraction Request pursuant to Section 27.6 of the Exchangeable Share Provisions and the redemption by ExchangeCo
pursuant to Section 27.7 of the Exchangeable Share Provisions, including, without limitation, all such actions and all such things as are necessary 

	 	
or desirable to enable and permit D-Wave Quantum to deliver or cause to be delivered D-Wave Quantum Shares or other
property to the holders of Exchangeable Shares in accordance with the provisions of Sections 27.6 or 27.7 of the Exchangeable Share Provisions; and 

  

	 	(h)	 not exercise its vote as a shareholder of ExchangeCo to initiate the voluntary liquidation, dissolution or
winding up of ExchangeCo or any other distribution of the assets of ExchangeCo among its shareholders for the purpose of winding up its affairs, nor take any action or omit to take any action that is designed to result in the liquidation,
dissolution or winding up of ExchangeCo or any other distribution of the assets of ExchangeCo among its shareholders for the purpose of winding up its affairs, without the prior approval of the holders of the Exchangeable Shares in accordance with
the Exchangeable Share Provisions as long as any Exchangeable Shares are outstanding. 

 2.2 Segregation of Funds. D-Wave Quantum will cause ExchangeCo to deposit a sufficient amount of funds in a separate account of ExchangeCo and segregate a sufficient amount of such other assets and property as is necessary to enable
ExchangeCo to pay or otherwise satisfy its obligations with respect to the applicable dividend, Liquidation Amount, Retraction Price or Redemption Price, in each case once such amounts become payable under the terms of this Agreement or the
Exchangeable Share Provisions. Once such amounts become payable, D-Wave Quantum will transfer such funds to ExchangeCo (through any intermediary entities) and ExchangeCo will use such funds, assets and
property so segregated exclusively for the payment of dividends and the payment or other satisfaction of the Liquidation Amount, the Retraction Price or the Redemption Price, as applicable, net of any corresponding withholding tax obligations and
for the remittance of such withholding tax obligations. 
 2.3 Reservation of D-Wave Quantum Shares. D-Wave Quantum hereby represents, warrants and covenants in favour of ExchangeCo and CallCo that D-Wave Quantum has reserved for issuance and shall, at all times while any
Exchangeable Shares are outstanding, keep available, free from pre-emptive and other rights, out of its authorized and unissued capital stock such number of D-Wave
Quantum Shares (or other shares or securities into which D-Wave Quantum Shares may be reclassified or changed as contemplated by Section 2.7): 

 

	 	(a)	 as is equal to the sum of (i) the number of Exchangeable Shares issued and outstanding from time to time
multiplied by the Exchangeable Share Exchange Ratio, and (ii) the number of Exchangeable Shares issuable upon the exercise of all rights to acquire Exchangeable Shares outstanding from time to time multiplied by the Exchangeable Share Exchange
Ratio; and 

  

	 	(b)	 as are now and may hereafter be required to enable and permit each of
D-Wave Quantum, CallCo and ExchangeCo to meet its obligations under the Voting and Exchange Trust Agreement, the Exchangeable Share Provisions and any other security or commitment relating to the Arrangement
pursuant to which D-Wave Quantum may now or hereafter be required to issue or cause to be issued D-Wave Quantum Shares. 

2.4 Notification of Certain Events. In order to assist D-Wave Quantum to comply with its obligations
hereunder and to permit D-Wave Quantum or CallCo to exercise, as the case may be, the Liquidation Call Right, the Retraction Call Right, the Change of Law Call Right or the

 
Redemption Call Right, as applicable, ExchangeCo shall notify D-Wave Quantum and CallCo of each of the following events at the time set forth below: 

 

	 	(a)	 in the event of any determination by the board of directors of ExchangeCo to institute voluntary liquidation,
dissolution or winding-up proceedings with respect to ExchangeCo or to effect any other distribution of the assets of ExchangeCo among its shareholders for the purpose of winding up its affairs, at least 60
days prior to the proposed effective date of such liquidation, dissolution, winding-up or other distribution; 

  

	 	(b)	 promptly upon the earlier of (i) receipt by ExchangeCo of notice of, and (ii) ExchangeCo otherwise
becoming aware of, any threatened or instituted claim, suit, petition or other proceedings with respect to the involuntary liquidation, dissolution or winding-up of ExchangeCo or to effect any other
distribution of the assets of ExchangeCo among its shareholders for the purpose of winding up its affairs; 

  

	 	(c)	 immediately, upon receipt by ExchangeCo of a Retraction Request; 

 

	 	(d)	 on the same date on which notice of redemption is given to holders of Exchangeable Shares, upon the
determination of a Redemption Date in accordance with the Exchangeable Share Provisions; 

  

	 	(e)	 as soon as practicable upon the issuance by ExchangeCo of any Exchangeable Shares or rights to acquire
Exchangeable Shares (other than the issuance of Exchangeable Shares and rights to acquire Exchangeable Shares pursuant to the Arrangement); and 

  

	 	(f)	 promptly, upon receiving notice of a Change of Law. 

2.5 Delivery of D-Wave Quantum Shares. Upon notice from CallCo or ExchangeCo of any event that requires
CallCo or ExchangeCo to deliver or cause to be delivered D-Wave Quantum Shares to any holder of Exchangeable Shares, D-Wave Quantum shall forthwith issue and deliver or
cause to be delivered the requisite number of D-Wave Quantum Shares for the benefit of CallCo or ExchangeCo, as appropriate, and CallCo or ExchangeCo, as the case may be, shall forthwith cause to be delivered
the requisite number of D-Wave Quantum Shares to be received by or for the benefit of the former holder of the surrendered Exchangeable Shares. All such D-Wave Quantum
Shares shall be duly authorized and validly issued as fully paid, non-assessable, free of preemptive rights and shall be free and clear of any lien, claim or encumbrance. 

2.6 Qualification of D-Wave Quantum Shares. 

 

	(1)	 D-Wave Quantum covenants and agrees that it shall use its commercially
reasonable efforts to (a) file a registration statement (the “Registration Statement”) on Form S-1 (or any successor form) under the U.S. Securities Act of 1933, as amended (the
“1933 Act”) to register any and all of the D-Wave Quantum Shares to be issued or delivered to holders of the Exchangeable Shares by D-Wave Quantum or
CallCo (including, for greater certainty, pursuant to the Exchange Right, as that term is defined in the Exchange and Voting Trust Agreement, or the Automatic Exchange Right), (b) cause the Registration Statement to become effective as promptly as
reasonably practicable after the time that any Exchangeable Shares are first issued (and in any event no later than the earlier of (i) 

	 	
the 60th calendar day (or if the Securities and Exchange Commission (the “Commission”) notifies D-Wave Quantum that it will “review” the Registration Statement, 90th calendar day) following the date on which any Exchangeable Shares are first
issued, and (ii) the 5th Business Day after the date D-Wave Quantum is notified (orally or in writing, whichever is earlier) by the Commission that the
Registration Statement will not be “reviewed” or will not be subject to further review), and (c) cause the Registration Statement (or a successor registration statement) to remain effective at all times that any Exchangeable Shares
remain outstanding. Without limiting the generality of the foregoing, D-Wave Quantum and CallCo each covenant and agree that it will take all such actions and do all such things as are reasonably necessary or
desirable to make such filings and seek such regulatory consents and approvals as are necessary so that the D-Wave Quantum Shares to be issued or delivered to holders of Exchangeable Shares pursuant to the
terms of the Exchangeable Share Provisions, the Voting and Exchange Trust Agreement and this Agreement will be offered, sold, issued and delivered in compliance with the 1933 Act and all applicable state securities laws, and applicable securities
laws in Canada and will use commercially reasonable efforts to ensure that the D-Wave Quantum Shares will not be subject to any hold period as contemplated by Rule 144 under the 1933 Act or subject to any
“hold period” resale restriction under National Instrument 45-102 Resale of Securities. D-Wave Quantum will in good faith expeditiously take all such
actions and do all such things as are reasonably necessary or desirable to cause all D-Wave Quantum Shares to be delivered to holders of Exchangeable Shares pursuant to the terms of the Exchangeable Share
Provisions, the Voting and Exchange Trust Agreement and this Agreement to be listed, quoted and posted for trading on all stock exchanges and quotation systems on which outstanding D-Wave Quantum Shares have
been listed by D-Wave Quantum and remain listed and are quoted or posted for trading at such time. 

  

	(2)	 Notwithstanding any other provision of the Exchangeable Share Provisions, or any term of this Agreement, the
Voting and Exchange Trust Agreement or the Plan of Arrangement, no D-Wave Quantum Shares shall be issued (and D-Wave Quantum will not be required to issue any D-Wave Quantum Shares) in connection with any liquidation, dissolution or winding-up of ExchangeCo, or any retraction, redemption or any other exchange, direct or indirect, of
Exchangeable Shares, if such issuance of D-Wave Quantum Shares would not be permitted by applicable laws. 

2.7 Economic Equivalence. 
  

	(1)	 So long as any Exchangeable Shares not owned by D-Wave Quantum or its
affiliates are outstanding: 

  

	 	(a)	 D-Wave Quantum shall not without the prior approval of ExchangeCo and
the prior approval of the holders of the Exchangeable Shares given in accordance with Section 27.10(b) of the Exchangeable Share Provisions: 

  

	 	(i)	 issue or distribute D-Wave Quantum Shares (or securities exchangeable
for or convertible into or carrying rights to acquire D-Wave Quantum Shares) to the holders of all or substantially all of the then outstanding D-Wave Quantum Shares by
way of stock or share dividend or other distribution, other than an issue of D-Wave Quantum Shares (or securities exchangeable for or convertible into or carrying rights to acquire D-Wave Quantum Shares) to holders of D-Wave Quantum Shares (A) who exercise an option to receive dividends in D-Wave Quantum
Shares (or securities 

	 	
exchangeable for or convertible into or carrying rights to acquire D-Wave Quantum Shares) in lieu of receiving cash dividends, or (B) pursuant to any
dividend reinvestment plan or scrip dividend or similar arrangement; or 

  

	 	(ii)	 issue or distribute rights, options or warrants to the holders of all or substantially all of the then
outstanding D-Wave Quantum Shares entitling them to subscribe for or to purchase D-Wave Quantum Shares (or securities exchangeable for or convertible into or carrying
rights to acquire D-Wave Quantum Shares); or 

  

	 	(iii)	 issue or distribute to the holders of all or substantially all of the then outstanding D-Wave Quantum Shares (A) shares or securities of D-Wave Quantum of any class other than D-Wave Quantum Shares (or securities
convertible into or exchangeable for or carrying rights to acquire D-Wave Quantum Shares), (B) rights, options, warrants or other assets other than those referred to in Section 2.7(1)(a)(ii), (C) evidence
of indebtedness of D-Wave Quantum or (D) assets of D-Wave Quantum; 

unless, in each case, ExchangeCo issues or distributes the economic equivalent of such rights, options, warrants, securities, shares, evidences
of indebtedness or other assets simultaneously to holders of the Exchangeable Shares including, without limitation, an adjustment to the Exchangeable Share Exchange Ratio in accordance with the terms of the Exchangeable Share Provisions; provided,
however, that, for greater certainty, the above restrictions shall not apply to any securities issued or distributed by D-Wave Quantum in order to give effect to and to consummate the transactions contemplated
by, and in accordance with, the Transaction Agreement and the Plan of Arrangement. 
  

	 	(b)	 D-Wave Quantum shall not without the prior approval of ExchangeCo and
the prior approval of the holders of the Exchangeable Shares given in accordance with Section 27.10(b) of the Exchangeable Share Provisions: 

  

	 	(i)	 subdivide, redivide or change the then outstanding D-Wave Quantum
Shares into a greater number of D-Wave Quantum Shares; or 

  

	 	(ii)	 reduce, combine, consolidate or change the then outstanding D-Wave
Quantum Shares into a lesser number of D-Wave Quantum Shares; or 

  

	 	(iii)	 reclassify or otherwise change the D-Wave Quantum Shares or effect an
amalgamation, merger, reorganization or other transaction affecting the D-Wave Quantum Shares; 

unless, in each case, the same or an economically equivalent change is made simultaneously to, or in the rights of the holders of, the
Exchangeable Shares; provided, however, that, for greater certainty, the above restrictions shall not apply to any securities issued or distributed by D-Wave Quantum in order to give effect to and to
consummate the transactions contemplated by, and in accordance with the Transaction Agreement and the Plan of Arrangement. 
  

	 	(c)	 D-Wave Quantum shall ensure that the record date for any event referred
to in Section 2.7(1)(a) or Section 2.7(1)(b), or (if no record date is applicable for such 

	 	
event) the effective date for any such event, is not less than five Business Days after the date on which such event is declared or announced by D-Wave
Quantum (with contemporaneous notification thereof by D-Wave Quantum to ExchangeCo). 

  

	(2)	 The board of directors of ExchangeCo shall determine, in good faith and in its sole discretion (with the
assistance of such financial or other advisors as the board of may determine), “economic equivalence” for the purposes of any event referred to in Section 2.7(1)(a) or Section 2.7(1)(b) and each such determination shall be
conclusive and binding on D-Wave Quantum. In making each such determination, the following factors shall, without excluding other factors determined by the board of directors of ExchangeCo to be relevant, be
considered by the board of directors of ExchangeCo: 

  

	 	(a)	 in the case of any stock or share dividend or other distribution payable in
D-Wave Quantum Shares, the number of such shares issued as a result of such stock or share dividend or other distribution in proportion to the number of D-Wave Quantum
Shares previously outstanding; 

  

	 	(b)	 in the case of the issuance or distribution of any rights, options or warrants to subscribe for or purchase D-Wave Quantum Shares (or securities exchangeable for or convertible into or carrying rights to acquire D-Wave Quantum Shares), the relationship between the exercise price of
each such right, option or warrant, the number of such rights, options or warrants to be issued or distributed in respect of each D-Wave Quantum Share and the Current Market Price of a D-Wave Quantum Share, the price volatility of the D-Wave Quantum Shares and the terms of any such instrument; 

 

	 	(c)	 in the case of the issuance or distribution of any other form of property (including, without limitation, any
shares or securities of D-Wave Quantum of any class other than D-Wave Quantum Shares, any rights, options or warrants other than those referred to in
Section 2.7(2)(b), any evidences of indebtedness of D-Wave Quantum or any assets of D-Wave Quantum), the relationship between the fair market value (as determined
by the board of directors of ExchangeCo in the manner above contemplated) of such property to be issued or distributed with respect to each outstanding D-Wave Quantum Share and the Current Market Price of a D-Wave Quantum Share; 

  

	 	(d)	 in the case of any subdivision, redivision or change of the then outstanding
D-Wave Quantum Shares into a greater number of D-Wave Quantum Shares or the reduction, combination, consolidation or change of the then outstanding D-Wave Quantum Shares into a lesser number of D-Wave Quantum Shares or any amalgamation, merger, arrangement, reorganization or other transaction affecting D-Wave Quantum Shares, the effect thereof upon the then outstanding D-Wave Quantum Shares; and 

 

	 	(e)	 in all such cases, the general taxation consequences of the relevant event to holders of Exchangeable Shares to
the extent that such consequences may differ from the taxation consequences to holders of D-Wave Quantum Shares as a result of differences between taxation laws of Canada and the United States (except for any
differing consequences arising as a result of differing marginal taxation rates and without regard to the individual circumstances of holders of Exchangeable Shares). 

	(3)	 ExchangeCo agrees that, to the extent required, upon due notice from
D-Wave Quantum, ExchangeCo shall use its best efforts to take or cause to be taken such steps as may be necessary for the purposes of ensuring that appropriate dividends are paid or other distributions are
made by ExchangeCo, or subdivisions, redivisions or changes are made to the Exchangeable Shares, in order to implement the required economic equivalence with respect to the D-Wave Quantum Shares and
Exchangeable Shares as provided for in this Section 2.7. 

 2.8 Tender Offers. In the event that a tender offer, share
exchange offer, issuer bid, take-over bid or similar transaction with respect to D-Wave Quantum Shares (an “Offer”) is proposed by D-Wave Quantum
or is proposed to D-Wave Quantum or its shareholders and is recommended by the board of directors of D-Wave Quantum, or is otherwise effected or to be effected with the
consent or approval of the board of directors of D-Wave Quantum, and the Exchangeable Shares are not redeemed by ExchangeCo or purchased by D-Wave Quantum or CallCo
pursuant to the Redemption Call Right, D-Wave Quantum and ExchangeCo will use reasonable efforts to take all such actions and do all such things as are necessary or desirable to enable and permit holders of
Exchangeable Shares (other than D-Wave Quantum and its affiliates) to participate in such Offer to the same extent and on an economically equivalent basis as the holders of
D-Wave Quantum Shares, without discrimination. Without limiting the generality of the foregoing, D-Wave Quantum and ExchangeCo will use reasonable efforts in good faith
to ensure that holders of Exchangeable Shares may participate in each such Offer without being required to retract Exchangeable Shares as against ExchangeCo (or, if so required, to ensure that any such retraction shall be effective only upon, and
shall be conditional upon, the closing of such Offer and only to the extent necessary to tender or deposit to the Offer). Nothing herein shall affect the rights of ExchangeCo to redeem, or D-Wave Quantum or
CallCo to purchase pursuant to the Redemption Call Right, Exchangeable Shares in the event of a D-Wave Quantum Extraordinary Transaction. 

2.9 D-Wave Quantum and Affiliates Not to Vote Exchangeable Shares. Each of D-Wave Quantum and CallCo covenants and agrees that it shall appoint and cause to be appointed proxyholders with respect to all Exchangeable Shares held by it and its affiliates for the sole purpose of attending
each meeting of holders of Exchangeable Shares in order to be counted as part of the quorum for each such meeting. Each of D-Wave Quantum and CallCo further covenants and agrees that it shall not, and shall
cause its affiliates not to, exercise any voting rights which may be exercisable by holders of Exchangeable Shares from time to time pursuant to the Exchangeable Share Provisions or pursuant to the provisions of the Business Corporations Act
(British Columbia) (or any successor or other corporate statute by which ExchangeCo may in the future be governed) with respect to any Exchangeable Shares held by it or by its affiliates in respect of any matter considered at any meeting of
holders of Exchangeable Shares; provided however, for further clarity, that this Section 2.9 shall not in any way restrict the right of D-Wave Quantum or any of its affiliates to vote their common shares
of ExchangeCo in accordance with the articles of ExchangeCo. 
 2.10 Ordinary Market Purchases. For greater certainty, nothing contained in
this Agreement, including, without limitation, the obligations of D-Wave Quantum contained in Section 2.8, shall limit the ability of D-Wave Quantum (or any of its
affiliates) to make ordinary market or other voluntary purchases of D-Wave Quantum Shares, including by private agreement, in accordance with applicable laws and regulatory or stock exchange requirements. 

2.11 Ownership of Outstanding Shares. Without the prior approval of ExchangeCo and the prior approval of the holders of the Exchangeable
Shares given in accordance with 

 
Section 27.10(b) of the Exchangeable Share Provisions, D-Wave Quantum covenants and agrees in favour of ExchangeCo that, as long as any outstanding
Exchangeable Shares not owned by D-Wave Quantum or its affiliates are outstanding, D-Wave Quantum will be and remain the direct or indirect beneficial owner of all
issued and outstanding common shares in the capital of ExchangeCo and CallCo. Notwithstanding the foregoing, D-Wave Quantum shall not be in violation of this Section 2.11 if any person or group of persons
acting jointly or in concert acquires all or substantially all of the assets of D-Wave Quantum or the D-Wave Quantum Shares pursuant to any merger or similar transaction
involving D-Wave Quantum pursuant to which D-Wave Quantum is not the surviving corporation. 

2.12 Reimbursement by D-Wave Quantum. D-Wave Quantum shall
reimburse ExchangeCo for, and indemnify and hold ExchangeCo harmless against, any expense or liability incurred by ExchangeCo with respect to the Exchangeable Shares. 

ARTICLE 3 
 D-WAVE QUANTUM SUCCESSORS 
 3.1 Certain Requirements in Respect of Combination, etc. Subject to Section
27.7 of the Exchangeable Share Provisions and Article 4 hereof with respect to a D-Wave Quantum Extraordinary Transaction, so long as any Exchangeable Shares not owned by
D-Wave Quantum or its affiliates are outstanding, D-Wave Quantum shall not enter into any transaction (whether by way of reorganization, consolidation, arrangement,
amalgamation, merger, business combination, transfer, sale, lease or otherwise) whereby all or substantially all of its undertaking, property and assets would become the property of any other person or, in the case of an amalgamation or merger or
combination, of the continuing corporation resulting therefrom, provided that it may do so if: 
  

	 	(a)	 such other person or continuing corporation (the “D-Wave
Quantum Successor”) by operation of law, becomes, without more, bound by the terms and provisions of this Agreement or, if not so bound, executes, prior to or contemporaneously with the consummation of such transaction, an agreement
supplemental hereto and such other instruments (if any) as are necessary or advisable to evidence the assumption by the D-Wave Quantum Successor of liability for all moneys payable and property deliverable
hereunder and the covenant of such D-Wave Quantum Successor to pay and deliver or cause to be paid and delivered the same and its agreement to observe and perform all the covenants and obligations of D-Wave Quantum under this Agreement; and 

  

	 	(b)	 such transaction shall be upon such terms and conditions as to preserve and not to impair any of the rights,
duties, powers and authorities of the other parties hereunder or the holders of the Exchangeable Shares. 

 3.2 Vesting of Powers
in Successor. Whenever the conditions of Section 3.1 have been duly observed and performed, the parties, if required by Section 3.1, shall execute and deliver the supplemental agreement provided for in Section 3.1(a) and
thereupon the D-Wave Quantum Successor and such other person that may then be the issuer of the D-Wave Quantum Shares shall possess and from time to time may exercise
each and every right and power of D-Wave Quantum under this Agreement in the name of D-Wave Quantum or otherwise and any act or proceeding by any provision of this
Agreement required to be done or performed by the board of directors of D-Wave Quantum or any officers of D-Wave Quantum may be done and performed with like force and
effect by the directors or officers of such D-Wave Quantum Successor. 

 3.3 Wholly-Owned Subsidiaries. Nothing herein shall be construed as preventing
(a) the amalgamation, merger or combination of any wholly-owned direct or indirect subsidiary of D-Wave Quantum (other than ExchangeCo or CallCo) with or into
D-Wave Quantum, (b) the winding-up, liquidation or dissolution of any wholly-owned direct or indirect subsidiary of D-Wave
Quantum (other than ExchangeCo or CallCo), provided that all of the assets of such subsidiary are transferred to D-Wave Quantum or another wholly-owned direct or indirect subsidiary of D-Wave Quantum, (c) any other distribution of the assets of any wholly-owned direct or indirect subsidiary of D-Wave Quantum (other than ExchangeCo or CallCo) among the
shareholders of such subsidiary for the purpose of winding up its affairs, and (d) any such transactions are expressly permitted by this Article 3. 

3.4 Successorship Transaction. Notwithstanding the foregoing provisions of this Article 3, in the event of a
D-Wave Quantum Extraordinary Transaction: 
  

	 	(a)	 in which D-Wave Quantum merges, combines or amalgamates with, or in
which all or substantially all of the then outstanding D-Wave Quantum Shares are acquired by, one or more other corporations to which D-Wave Quantum is, immediately
before such merger, combination, amalgamation or acquisition, “related” within the meaning of the Income Tax Act (Canada) (otherwise than by virtue of a right referred to in paragraph 251(5)(b) thereof); 

 

	 	(b)	 which does not result in an acceleration of the Redemption Date in accordance with paragraph (ii) of the
definition of Redemption Date in the Exchangeable Share Provisions; and

Article 4 from Beneficiaries on the record date established by D-Wave Quantum or by applicable law for such D-Wave Quantum Meeting who are entitled to instruct the
Trustee as to the voting thereof; 

  

	 	(b)	 to the extent that no instructions are received from a Beneficiary with respect to the Voting Rights in respect
of which such Beneficiary is entitled to instruct the Trustee, the Trustee shall not exercise or permit the exercise of such Voting Rights; and 

  

	 	(c)	 without prejudice to paragraph (b) above, under no circumstances shall the Trustee exercise or permit the
exercise of a number of Voting Rights which is greater than the number of Exchangeable Shares outstanding at the relevant time multiplied by the Exchangeable Share Exchange Ratio. 

4.2 Number of Votes. With respect to all meetings of shareholders of D-Wave Quantum at which holders of D-Wave Quantum Shares are entitled to vote (each, a “D-Wave Quantum Meeting”), each Beneficiary shall be entitled to instruct the Trustee to cast and
exercise, in the manner instructed, that number of votes equal to the Equivalent Vote Amount for each Exchangeable Share owned of record by such Beneficiary at the close of business on the record date established by
D-Wave Quantum or by applicable law for such D-Wave Quantum Meeting, multiplied by the Exchangeable Share Exchange Ratio, and in respect of each Beneficiary, rounded
down to the nearest whole vote (collectively, the “Beneficiary Votes”), in respect of each matter, question, proposal or proposition to be voted on at such D-Wave Quantum Meeting. 

 4.3 Mailings to Shareholders. 

 

	(1)	 With respect to each D-Wave Quantum Meeting, the Trustee will mail or
cause to be mailed (or otherwise communicate in the same manner as D-Wave Quantum utilizes in communications to holders of D-Wave Quantum Shares, subject to applicable
regulatory requirements and to the Trustee being advised in writing of such manner of communications and provided that such manner of communications is reasonably available to the Trustee) to each Beneficiary named in the applicable List on the same
day as the mailing (or other communication) with respect thereto is commenced by D-Wave Quantum to its shareholders: 

  

	 	(a)	 a copy of such mailing, together with any related materials, including, without limitation, any proxy circular
or information statement or listing particulars, to be provided to shareholders of D-Wave Quantum; 

  

	 	(b)	 a statement that such Beneficiary is entitled to instruct the Trustee as to the exercise of the Beneficiary
Votes with respect to such D-Wave Quantum Meeting or, pursuant to Section 4.7, to attend such D-Wave Quantum Meeting and to exercise personally the Beneficiary
Votes thereat, as the proxy of the Trustee; 

  

	 	(c)	 a statement as to the manner in which such instructions may be given to the Trustee, including an express
indication that instructions may be given to the Trustee to give (A) a proxy to such Beneficiary or their or its designee to exercise personally such holder’s Beneficiary Votes, or (B) a proxy to a designated agent or other
representative of D-Wave Quantum to exercise such holder’s Beneficiary Votes; 

  

	 	(d)	 a statement that if no such instructions are received from such Beneficiary, the Beneficiary Votes to which the
Beneficiary is entitled will not be exercised; 

  

	 	(e)	 a form of direction such Beneficiary may use to direct and instruct the Trustee as contemplated herein; and

  

	 	(f)	 a statement of (A) the time and date by which such instructions must be received by the Trustee in order
for such instructions to be binding upon the Trustee, which in the case of a D-Wave Quantum Meeting shall not be earlier than the close of business on the Business Day immediately prior to the date by which D-Wave Quantum has required proxies to be deposited for such meeting, and (B) of the method for revoking or amending such instructions. 

 

	(2)	 The materials referred to in this Section 4.3 shall be provided to the Trustee by D-Wave Quantum, and the materials referred to in Sections 4.3(1)(b), 4.3(1)(c), 4.3(1)(d), 4.3(1)(e) and 4.3(1)(f) shall be subject to reasonable comment by the Trustee in a timely manner. Subject to the foregoing, D-Wave Quantum shall ensure that the materials to be provided to the Trustee are provided in sufficient time to permit the Trustee to comment as aforesaid and to send all materials to each Beneficiary at the same
time as such materials are first sent to holders of D-Wave Quantum Shares. D-Wave Quantum agrees not to communicate with holders of
D-Wave Quantum Shares with respect to the materials referred to in this Section 4.3 otherwise than by mail unless such method of communication is also reasonably available to the Trustee for communication
with the Beneficiaries. Notwithstanding the foregoing, D-Wave Quantum may, at its option, 

	 	
exercise the duties of the Trustee to deliver copies of all materials to all Beneficiaries as required by this Section 4.3 so long as, in each case,
D-Wave Quantum delivers a certificate to the Trustee stating that D-Wave Quantum has undertaken to perform the obligations of the Trustee set forth in this
Section 4.3. 

  

	(3)	 For the purpose of determining the number of Beneficiary Votes to which a Beneficiary is entitled in respect of
any D-Wave Quantum Meeting, the number of Exchangeable Shares owned of record by the Beneficiary shall be determined at the close of business on the record date established by
D-Wave Quantum or by applicable law for purposes of determining shareholders entitled to vote at such D-Wave Quantum Meeting.
D-Wave Quantum shall notify the Trustee of any decision of the board of directors of D-Wave Quantum with respect to the calling of any
D-Wave Quantum Meeting and shall provide all necessary information and materials to the Trustee in each case promptly and, in any event, in reasonably sufficient time to enable the Trustee to perform the
obligations of the Trustee set forth in this Section 4.3. 

 4.4 Copies of Shareholder Information. D-Wave Quantum shall deliver to the Trustee copies of all proxy materials (including, without limitation, notices of D-Wave Quantum Meetings but excluding proxies to vote D-Wave Quantum Shares), information statements, reports (including, without limitation, all interim and annual financial statements) and other written communications that, in each case, are to be distributed by D-Wave Quantum from time to time to holders of D-Wave Quantum Shares in sufficient quantities and in sufficient time so as to enable the Trustee to send or cause to send those
materials to each Beneficiary at the same time as such materials are first sent to holders of D-Wave Quantum Shares. The Trustee shall mail or otherwise send to each Beneficiary, at the expense of D-Wave Quantum, copies of all such materials (and all materials specifically directed to the Beneficiaries or to the Trustee for the benefit of the Beneficiaries by D-Wave
Quantum) received by the Trustee from D-Wave Quantum contemporaneously with the sending of such materials to holders of D-Wave Quantum Shares. The Trustee shall also
make available for inspection during regular business hours by any Beneficiary at the Trustee’s principal office in Vancouver, British Columbia all proxy materials, information statements, reports and other written communications that
are: 
  

	 	(a)	 received by the Trustee as the registered holder of the Special Voting Share and made available by D-Wave Quantum generally to the holders of D-Wave Quantum Shares; or 

  

	 	(b)	 specifically directed to the Beneficiaries or to the Trustee for the benefit of the Beneficiaries by D-Wave Quantum. 

 Notwithstanding the foregoing, D-Wave Quantum
may, at its option, exercise the duties of the Trustee to deliver copies of all such materials to all Beneficiaries as required by this Section 4.4 so long as, in each case, D-Wave Quantum delivers a
certificate to the Trustee stating that D-Wave Quantum has undertaken to perform the obligations of the Trustee set forth in this Section 4.4. 

4.5 Other Materials. As soon as reasonably practicable after receipt by D-Wave Quantum or shareholders
of D-Wave Quantum (if such receipt is known by D-Wave Quantum) of any material sent or given by or on behalf of a third party to holders of D-Wave Quantum Shares generally, including dissident proxy and information circulars (and related information and material) and take-over bid and securities exchange take-over bid circulars (and related information
and material), provided such material has not been sent to the Beneficiaries by or on 

 
behalf of such third party, D-Wave Quantum shall use its reasonable efforts to obtain and deliver to the Trustee copies thereof in sufficient quantities so
as to enable the Trustee to forward such material (unless the same has been provided directly to Beneficiaries by such third party) to each Beneficiary as soon as possible thereafter. As soon as reasonably practicable after receipt thereof, the
Trustee shall mail or otherwise send to each Beneficiary, at the expense of D-Wave Quantum, copies of all such materials received by the Trustee from D-Wave Quantum. The
Trustee shall also make available for inspection during regular business hours by any Beneficiary at the Trustee’s principal office in Vancouver, British Columbia copies of all such materials. Notwithstanding the foregoing, D-Wave Quantum may, at its option, exercise the duties of the Trustee to deliver copies of all such materials to all Beneficiaries as required by this Section 4.5 so long as, in each case, D-Wave Quantum delivers a certificate to the Trustee stating that D-Wave Quantum has undertaken to perform the obligations of the Trustee set forth in this Section 4.5.

 4.6 List of Persons Entitled to Vote. ExchangeCo shall (a) prior to each annual or other
D-Wave Quantum Meeting, and (b) forthwith upon each request made at any time by the Trustee in writing, prepare or cause to be prepared a list (a “List”) of the names and addresses of the
Beneficiaries arranged in alphabetical order and showing the number of Exchangeable Shares held of record by each such Beneficiary, in each case at the close of business on the date specified by the Trustee in such request or, in the case of a List
prepared in connection with a D-Wave Quantum Meeting, at the close of business on the record date established by D-Wave Quantum or pursuant to applicable law for
determining the holders of D-Wave Quantum Shares entitled to receive notice of and/or to vote at such D-Wave Quantum Meeting. Each such List shall be delivered to the
Trustee promptly after receipt by ExchangeCo of such request or the record date for such meeting and, in any event, within sufficient time as to permit the Trustee to perform its obligations under this Agreement.
D-Wave Quantum agrees to give ExchangeCo notice (with a copy to the Trustee) of the calling of any D-Wave Quantum Meeting together with the record date therefor,
sufficiently prior to the date of the calling of such meeting or seeking of such consent, so as to enable ExchangeCo to perform its obligations under this Section 4.6. 

4.7 Entitlement to Direct Votes. Subject to Section 4.8 and Section 4.11, any Beneficiary named in a List prepared in connection with
any D-Wave Quantum Meeting shall be entitled to (a) instruct the Trustee in the manner described in Section 4.2 with respect to the exercise of the Beneficiary Votes to which such Beneficiary is
entitled, (b) attend such meeting and personally exercise thereat (or to exercise with respect to any written consent), as the proxy of the Trustee, the Beneficiary Votes to which such Beneficiary is entitled, or (c) appoint a third party
as the proxy of the Trustee to attend such meeting and exercise thereat the Beneficiary Votes to which such Beneficiary is entitled except, in each case, to the extent that such Beneficiary has transferred the ownership of any Exchangeable Shares in
respect of which such Beneficiary is entitled to Beneficiary Votes after the close of business on the record date for such meeting or seeking of consent. 

4.8 Voting by Trustee and Attendance of Trustee Representative at Meeting. 
  

	(1)	 In connection with each D-Wave Quantum Meeting, the Trustee shall
exercise, either in person or by proxy, in accordance with the instructions received from a Beneficiary pursuant to Section 4.2, the Beneficiary Votes as to which such Beneficiary is entitled to direct the vote (or any lesser number thereof as
may be set forth in the instructions) other than any Beneficiary Votes that are the subject of Section 4.8(2); provided, however, that such written instructions are received by the Trustee from the Beneficiary prior to the time

	 	
and date fixed by the Trustee for receipt of such instruction in the notice given by the Trustee to the Beneficiary pursuant to Section 4.3. 

 

	(2)	 To the extent so instructed in accordance with the terms of this Agreement, the Trustee shall cause a
representative who is empowered by it to sign and deliver, on behalf of the Trustee, proxies for Voting Rights enabling a Beneficiary to attend a D-Wave Quantum Meeting. Upon submission by a Beneficiary (or
its designee) named in the List prepared in connection with the relevant meeting of identification satisfactory to the Trustee’s representative, and at the Beneficiary’s request, such representative shall sign and deliver to such
Beneficiary (or its designee) a proxy to exercise personally the Beneficiary Votes as to which such Beneficiary is otherwise entitled hereunder to direct the vote, if such Beneficiary either (i) has not previously given the Trustee instructions
pursuant to Section 4.3 in respect of such meeting or (ii) submits to such representative written revocation of any such previous instructions. At such meeting, the Beneficiary (or its designee) exercising such Beneficiary Votes in
accordance with such proxy shall have the same rights in respect of such Beneficiary Votes as the Trustee to speak at the meeting in respect of any matter, question, proposal or proposition, to vote by way of ballot at the meeting in respect of any
matter, question, proposal or proposition, and to vote at such meeting by way of a show of hands in respect of any matter, question, proposal or proposition. 

4.9 Distribution of Written Materials. Any written materials distributed by the Trustee to the Beneficiaries pursuant to this Agreement shall be
sent by mail (or otherwise communicated in the same manner as D-Wave Quantum utilizes in communications to holders of D-Wave Quantum Shares, subject to applicable
regulatory requirements and to the Trustee being advised in writing of such manner of communications and provided that such manner of communications is reasonably available to the Trustee) to each Beneficiary at its address as shown on the register
of holders of Exchangeable Shares maintained by the registrar. In connection with each such distribution, ExchangeCo shall provide or cause to be provided to the Trustee for purposes of communication, on a timely basis and without charge or other
expense, a current List, and upon the request of the Trustee, mailing labels to enable the Trustee to carry out its duties under this Agreement. ExchangeCo’s obligations under this Section 4.9 shall be deemed satisfied to the extent D-Wave Quantum exercises its option to perform the duties of the Trustee to deliver copies of materials to each Beneficiary and ExchangeCo provides the required information and materials to D-Wave Quantum. 
 4.10 Termination of Voting Rights. Except as otherwise provided in the Exchangeable Share
Provisions, all of the rights of a Beneficiary with respect to the Beneficiary Votes exercisable in respect of the Exchangeable Shares held by such Beneficiary, including the right to instruct the Trustee as to the voting of or to vote personally
such Beneficiary Votes, shall lapse and be deemed to be surrendered by the Beneficiary to D-Wave Quantum or CallCo, as the case may be, and such Beneficiary Votes and the Voting Rights represented thereby
shall cease immediately upon: 
  

	 	(a)	 the delivery by such holder to the Trustee of the certificates (if any) representing such Exchangeable Shares
and other required documentation in connection with the exercise by the Beneficiary of the Exchange Right; 

  

	 	(b)	 the occurrence of the automatic exchange of Exchangeable Shares for
D-Wave Quantum Shares, as specified in Article 5 (unless D-Wave Quantum shall not have 

	 	
delivered the requisite D-Wave Quantum Shares deliverable in exchange therefor to the Trustee pending delivery to the Beneficiaries); 

 

	 	(c)	 the retraction or redemption of Exchangeable Shares pursuant to Section 27.6 or 27.7 of the Exchangeable Share
Provisions; 

  

	 	(d)	 the effective date of the liquidation, dissolution or winding-up of
ExchangeCo or any other distribution of the assets of ExchangeCo among its shareholders for the purpose of winding up its affairs pursuant to Section 27.5 of the Exchangeable Share Provisions; or 

 

	 	(e)	 upon the purchase of Exchangeable Shares from the holder thereof by
D-Wave Quantum or CallCo, as the case may be, pursuant to the exercise by D-Wave Quantum or CallCo of the Liquidation Call Right, the Redemption Call Right, the Change
of Law Call Right or the Retraction Call Right (unless, in any case, D-Wave Quantum or CallCo, as the case may be, shall not have delivered the requisite consideration deliverable in exchange therefor).

 4.11 Disclosure of Interest in Exchangeable Shares. The Trustee or ExchangeCo shall be entitled to require any
Beneficiary or any person whom the Trustee or ExchangeCo, as the case may be, knows or has reasonable cause to believe holds any interest whatsoever in an Exchangeable Share to (a) confirm that fact, or (b) give such details as to whom has
an interest in such Exchangeable Share, in each case as would be required (if the Exchangeable Shares were a class of “equity securities” of ExchangeCo) under Section 5.2 of National Instrument
62-104 Take-Over Bids and Issuer Bids or as would be required under the articles of D-Wave Quantum or any laws or regulations, or pursuant to the rules or
regulations of any regulatory agency, if and only to the extent that the Exchangeable Shares (as multiplied by the Exchangeable Share Exchange Ratio) were D-Wave Quantum Shares. If a Beneficiary does not
provide the information required to be provided by such Beneficiary pursuant to this Section 4.11, the board of directors of D-Wave Quantum may take any action permitted under the articles or bylaws of D-Wave Quantum or any laws or regulations, or pursuant to the rules or regulations of any regulatory agency, with respect to the Voting Rights relating to the Exchangeable Shares held by such Beneficiary as if, and
only to that the extent that, the Exchangeable Shares (as multiplied by the Exchangeable Share Exchange Ratio) were D-Wave Quantum Shares. 

ARTICLE 5 
 EXCHANGE AND
AUTOMATIC EXCHANGE 
 5.1 Grant and Ownership of the Exchange Right and Automatic Exchange Right. 

 

	(1)	 D-Wave Quantum and, in the case of the Exchange Right, CallCo hereby
grant to the Trustee as trustee for and on behalf of, and for the use and benefit of, the Beneficiaries (i) the right (the “Exchange Right”), upon the occurrence and during the continuance of an Insolvency Event, to require
CallCo or D-Wave Quantum (provided that D-Wave Quantum may, in its sole discretion, cause CallCo to purchase in its stead to the extent permitted by applicable law) to
purchase from each or any Beneficiary all or any part of the Exchangeable Shares held by such Beneficiary, all in accordance with the provisions of this Agreement, and (ii) the Automatic Exchange Right. Each of
D-Wave Quantum and CallCo hereby acknowledge receipt from the Trustee as trustee for and on behalf of the Beneficiaries of good and valuable consideration (and the adequacy thereof) for the grant

	 	
of the Exchange Right and the Automatic Exchange Right by D-Wave Quantum or CallCo, as the case may be, to the Trustee. 

 

	(2)	 During the term of the Trust, and subject to the terms and conditions of this Agreement, the Trustee shall
possess and be vested with full legal ownership of the Exchange Right and the Automatic Exchange Right and shall be entitled to exercise all of the rights and powers of an owner with respect to the Exchange Right and the Automatic Exchange Right,
provided that the Trustee shall: 

  

	 	(a)	 hold the Exchange Right and the Automatic Exchange Right and the legal title thereto as trustee solely for the
use and benefit of the Beneficiaries in accordance with the provisions of this Agreement; and 

  

	 	(b)	 except as specifically authorized by this Agreement, have no power or authority to exercise or otherwise deal
in or with the Exchange Right or the Automatic Exchange Right, and the Trustee shall not exercise any such rights for any purpose other than the purposes for which the Trust is created pursuant to this Agreement. 

5.2 Legended Non-transferable Acknowledgements. ExchangeCo shall cause each non-transferrable acknowledgement representing Exchangeable Shares to bear the following legend notifying the Beneficiary in respect of the Exchangeable Shares represented by such
non-transferrable acknowledgement of (a) their or its right to instruct the Trustee with respect to the exercise of the Exchange Right in respect of the Exchangeable Shares held by such Beneficiary and
(b) the Automatic Exchange Right: 
 THE SHARES REPRESENTED BY THIS NON-TRANSFERRABLE
ACKNOWLEDGEMENT ARE SUBJECT TO THE TERMS AND CONDITIONS OF A VOTING AND EXCHANGE TRUST AGREEMENT WHICH PROVIDES FOR, AMONG OTHER THINGS, (A) THE RIGHT OF THE HOLDER TO INSTRUCT THE TRUSTEE IN RESPECT OF THE EXERCISE OF THE EXCHANGE RIGHT, AND
(B) AN AUTOMATIC EXCHANGE RIGHT. 
 5.3 General Exercise of Exchange Right. The Exchange Right shall be and remain vested in and
exercisable by the Trustee. Subject to Section 7.15, the Trustee shall exercise the Exchange Right only on the basis of instructions received pursuant to this Article 5 from Beneficiaries entitled to instruct the Trustee as to the exercise
thereof. To the extent that no instructions are received from any Beneficiary with respect to the Exchange Right, the Trustee shall not exercise or permit the exercise of the Exchange Right. 

5.4 Purchase Price. The purchase price payable by D-Wave Quantum or CallCo, as the case may be, for each
Exchangeable Share to be purchased by D-Wave Quantum or CallCo, as the case may be, pursuant to the exercise of the Exchange Right shall be an amount per share equal to the Exchangeable Share Price on the last
Business Day prior to the day of the closing of the purchase and sale of such Exchangeable Share pursuant to such exercise of the Exchange Right, which price may be satisfied only by D-Wave Quantum or CallCo,
as the case may be, delivering or causing to be delivered to the Trustee, on behalf of the relevant Beneficiary, the Exchangeable Share Consideration representing such Exchangeable Share Price. Upon payment by
D-Wave Quantum or CallCo, as the case may be, of the Exchangeable Share Price, the relevant Beneficiary shall cease to have any right to be paid any amount in respect of declared and unpaid dividends on each
such Exchangeable Share by ExchangeCo and ExchangeCo shall cease to be obligated to pay any amount in respect of such dividends. 

 5.5 Exercise Instructions. Subject to the terms and conditions set forth herein, a Beneficiary
shall be entitled upon the occurrence and during the continuance of an Insolvency Event, to instruct the Trustee to exercise the Exchange Right with respect to all or any part of the Exchangeable Shares registered in the name of such Beneficiary. In
order to cause the Trustee to exercise the Exchange Right with respect to all or any part of the Exchangeable Shares registered in the name of a Beneficiary, such Beneficiary shall deliver to the Trustee, in person or by certified or registered
mail, at its principal office in Vancouver, British Columbia or at such other place as the Trustee may from time to time designate by written notice to the Beneficiaries, the certificates (if any) representing the Exchangeable Shares which such
Beneficiary desires D-Wave Quantum or CallCo to purchase, duly endorsed in blank for transfer, and accompanied by such other documents and instruments as may be required to effect a transfer of the
Exchangeable Shares under the Business Corporations Act (British Columbia), the articles of ExchangeCo and such additional documents and instruments as D-Wave Quantum, ExchangeCo or the Trustee may
reasonably require together with: 
  

	 	(a)	 a duly completed form of notice of exercise of the Exchange Right, contained on the reverse of or attached to
the Exchangeable Share non-transferable acknowledgements, stating (i) that the Beneficiary thereby instructs the Trustee to exercise the Exchange Right so as to require
D-Wave Quantum or CallCo to purchase from the Beneficiary the number of Exchangeable Shares specified therein, (ii) that such Beneficiary has good title to and owns all such Exchangeable Shares to be
acquired by D-Wave Quantum or CallCo free and clear of all liens, claims, security interests and encumbrances, and (iii) the names in which the D-Wave Quantum
Shares issuable in connection with the exercise of the Exchange Right are to be issued; and 

  

	 	(b)	 payment (or evidence satisfactory to D-Wave Quantum, ExchangeCo and the
Trustee of payment) of the taxes (if any) payable as contemplated by Section 5.8 of this Agreement; 

 provided that if only a part
of the Exchangeable Shares represented by any non-transferable acknowledgement are to be purchased by D-Wave Quantum or CallCo pursuant to the exercise of the Exchange
Right, a new non-transferable acknowledgement for the balance of such Exchangeable Shares shall be issued to the holder at the expense of ExchangeCo. 

5.6 Delivery of D-Wave Quantum Shares; Effect of Exercise. Promptly after the receipt by the Trustee of
the certificates representing the Exchangeable Shares (if any) which a Beneficiary desires D-Wave Quantum or CallCo to purchase pursuant to the exercise of the Exchange Right, together with a notice of
exercise and such other documents and instruments specified by Section 5.5, the Trustee shall notify D-Wave Quantum, CallCo and ExchangeCo of its receipt of the same, which notice to D-Wave Quantum, CallCo and ExchangeCo shall constitute exercise of the Exchange Right by the Trustee on behalf of such Beneficiary in respect of such Exchangeable Shares, and
D-Wave Quantum or CallCo, as the case may be, shall promptly thereafter deliver or cause to be delivered to the Trustee, for delivery to such Beneficiary (or to such other persons, if any, properly designated
by such Beneficiary) the Exchangeable Share Consideration deliverable in connection with such exercise of the Exchange Right; provided, however, that no such delivery shall be made unless and until the Beneficiary requesting the same shall have paid
(or provided evidence satisfactory to D-Wave Quantum, CallCo, ExchangeCo and the Trustee of the payment of) the taxes (if any) payable as contemplated by Section 5.8 of this Agreement. Immediately upon
the giving of notice by the Trustee to D-Wave Quantum, CallCo and ExchangeCo of any exercise of the Exchange Right, as provided in this 

 
Section 5.6, the closing of the transaction of purchase and sale contemplated by the Exchange Right shall be deemed to have occurred, and the Beneficiary in respect of such Exchangeable
Shares shall be deemed to have transferred to D-Wave Quantum or CallCo, as the case may be, all of such Beneficiary’s right, title and interest in and to such Exchangeable Shares and in the related
interest in the Trust Estate and shall cease to be a holder of such Exchangeable Shares and shall not be entitled to exercise any of the rights of a holder in respect thereof, other than the right to receive the total Exchangeable Share
Consideration in respect of such Exchangeable Shares, unless such Exchangeable Share Consideration is not delivered by D-Wave Quantum or CallCo, as the case may be, to the Trustee for delivery to such
Beneficiary (or to such other person, if any, properly designated by such Beneficiary) within five Business Days of the date of the giving of such notice by the Trustee, in which case the rights of the Beneficiary shall remain unaffected until such
Exchangeable Share Consideration is so delivered. Upon delivery of such Exchangeable Share Consideration to the Trustee, the Trustee shall promptly deliver such Exchangeable Share Consideration to such Beneficiary (or to such other person, if any,
properly designated by such Beneficiary). Concurrently with the closing of the transaction of purchase and sale contemplated by such exercise of the Exchange Right, the Beneficiary shall be considered and deemed for all purposes to be the holder of
the D-Wave Quantum Shares delivered to it pursuant to such exercise of the Exchange Right. 
 5.7 Exercise
of Exchange Right Subsequent to Retraction. In the event that a Beneficiary has exercised its retraction right under Section 27.6(1) of the Exchangeable Share Provisions to require ExchangeCo to redeem any or all of the Exchangeable Shares held
by the Beneficiary (the “Retracted Shares”) and is notified by ExchangeCo pursuant to Section 27.6(1)(c) of the Exchangeable Share Provisions that ExchangeCo will not be permitted as a result of solvency requirements of
applicable law to redeem all such Retracted Shares, subject to receipt by the Trustee of written notice to that effect from ExchangeCo, and provided that neither D-Wave Quantum nor CallCo shall have exercised
its Retraction Call Right with respect to the Retracted Shares and that the Beneficiary shall not have revoked the retraction request delivered by the Beneficiary to ExchangeCo pursuant to Section 27.6(1)(d) of the Exchangeable Share
Provisions, the retraction request will constitute and will be deemed to constitute notice from the Beneficiary to the Trustee instructing the Trustee to exercise the Exchange Right with respect to those Retracted Shares that ExchangeCo is unable to
redeem. In any such event, ExchangeCo hereby agrees with the Trustee, and in favour of the Beneficiary, promptly to notify the Trustee of such prohibition against ExchangeCo and to forward or cause to be forwarded to the Trustee all relevant
materials delivered by the Beneficiary to ExchangeCo or to the Transfer Agent in connection with such proposed redemption of the Retracted Shares and the Trustee will thereupon exercise the Exchange Right with respect to the Retracted Shares that
ExchangeCo is not permitted to redeem and will require D-Wave Quantum or, at the option of D-Wave Quantum, CallCo, to purchase such shares in accordance with the
provisions of this Article 5. 
 5.8 Stamp or Other Transfer Taxes. Upon any sale or transfer of Exchangeable Shares to D-Wave Quantum or CallCo pursuant to the exercise of the Exchange Right or the Automatic Exchange Right, the D-Wave Quantum Shares to be delivered in connection with the
payment of the purchase price therefor shall be issued in the name of the Beneficiary in respect of the Exchangeable Shares so sold or transferred or in such names as such Beneficiary may otherwise direct in writing without charge to the holder of
the Exchangeable Shares so sold or transferred; provided, however, that such Beneficiary (a) shall pay (and none of D-Wave Quantum, CallCo, ExchangeCo or the Trustee shall be required to pay) any
documentary, stamp, transfer or other taxes or duties that may be payable in respect of any sale or transfer involved in the issuance or delivery of such shares to a person other than such Beneficiary including, without limitation, in the event that
Exchangeable Shares are being delivered, sold or transferred in the 

 
name of a clearing service or depositary or a nominee thereof, or (b) shall have evidenced to the satisfaction of D-Wave Quantum, CallCo, ExchangeCo
and the Trustee that such taxes or duties (if any) have been paid. 
 5.9 Notice of Insolvency Event. As soon as reasonably practicable
following the occurrence of an Insolvency Event or any event that with the giving of notice or the passage of time or both would be an Insolvency Event, D-Wave Quantum and ExchangeCo shall give written notice
thereof to the Trustee. As soon as reasonably practicable after receiving notice from D-Wave Quantum or ExchangeCo of the occurrence of an Insolvency Event, or upon the Trustee otherwise becoming aware of an
Insolvency Event, the Trustee shall mail to each Beneficiary, at the expense of D-Wave Quantum (such funds to be received in advance), a notice of such Insolvency Event in the form provided by D-Wave Quantum, which notice shall contain a brief statement of the rights of the Beneficiaries with respect to the Exchange Right. 

5.10 U.S. Securities Law Compliance and Listing of D-Wave Quantum Shares.
D-Wave Quantum covenants and agrees that it shall use its commercially reasonable efforts to (a) file a registration statement (the “Registration Statement”) on Form S-1 (or any successor form) under the U.S. Securities Act of 1933, as amended (the “1933 Act”) to register any and all of the D-Wave Quantum Shares to be
issued or delivered to holders of the Exchangeable Shares by D-Wave Quantum or CallCo (including, for greater certainty, pursuant to the Exchange Right or the Automatic Exchange Right), (b) cause the
Registration Statement to become effective as promptly as reasonably practicable after the time that any Exchangeable Shares are first issued (and in any event no later than the earlier of (i) the
60th calendar day (or if the Securities and Exchange Commission (the “Commission”) notifies D-Wave Quantum that it will “review”
the Registration Statement, 90th calendar day) following the date on which any Exchangeable Shares are first issued, and (ii) the 5th
Business Day after the date D-Wave Quantum is notified (orally or in writing, whichever is earlier) by the Commission that the Registration Statement will not be “reviewed” or will not be subject to
further review), and (c) cause the Registration Statement (or a successor registration statement) to remain effective at all times that any Exchangeable Shares remain outstanding. Without limiting the generality of the foregoing, D-Wave Quantum and CallCo each covenant and agree that it will take all such actions and do all such things as are reasonably necessary or desirable to make such filings and seek such regulatory consents and
approvals as are necessary so that the D-Wave Quantum Shares to be issued or delivered to holders of Exchangeable Shares pursuant to the terms of the Exchangeable Share Provisions, the Support Agreement and
this Agreement will be offered, sold, issued and delivered in compliance with the 1933 Act and all applicable state securities laws, and applicable securities laws in Canada and will use commercially reasonable efforts to ensure that the D-Wave Quantum Shares will not be subject to any hold period as contemplated by Rule 144 under the 1933 Act or subject to any “hold period” resale restriction under National Instrument 45-102 Resale of Securities. D-Wave Quantum will in good faith expeditiously take all such actions and do all such things as are reasonably necessary or desirable to
cause all D-Wave Quantum Shares to be delivered to holders of Exchangeable Shares pursuant to the terms of the Exchangeable Share Provisions, the Support Agreement and this Agreement to be listed, quoted and
posted for trading on all stock exchanges and quotation systems on which outstanding D-Wave Quantum Shares have been listed by D-Wave Quantum and remain listed and are
quoted or posted for trading at such time. 
 5.11 D-Wave Quantum Shares. D-Wave Quantum hereby represents, warrants and covenants that the D-Wave Quantum Shares deliverable as described herein will be duly authorized and validly issued as fully
paid and non-assessable and shall be free and clear of any lien, claim or encumbrance. 

 5.12 Automatic Exchange on Liquidation of D-Wave Quantum 

 

	(1)	 D-Wave Quantum shall give the Trustee written notice of each of the
following events (each, a “Liquidation Event”) at the time set forth below: 

  

	 	(a)	 in the event of any determination by the board of directors of D-Wave
Quantum to institute voluntary liquidation, dissolution or winding-up proceedings with respect to D-Wave Quantum or to effect any other distribution of assets of D-Wave Quantum among its shareholders for the purpose of winding up its affairs, at least 30 days prior to the proposed effective date of such liquidation, dissolution,
winding-up or other distribution; and 

  

	 	(b)	 as soon as practicable following the earlier of (A) receipt by
D-Wave Quantum of notice of, and (B) D-Wave Quantum otherwise becoming aware of any instituted claim, suit, petition or other proceedings with respect to the
involuntary liquidation, dissolution or winding-up of D-Wave Quantum or to effect any other distribution of assets of D-Wave
Quantum among its shareholders for the purpose of winding up its affairs, in each case where D-Wave Quantum has failed to contest in good faith any such proceeding commenced in respect of D-Wave Quantum within 30 days of becoming aware thereof. 

  

	(2)	 As soon as practicable following receipt by the Trustee from D-Wave
Quantum of notice of a Liquidation Event, the Trustee shall give notice thereof to the Beneficiaries. Such notice shall be provided by D-Wave Quantum to the Trustee and shall include a brief description of the
automatic exchange of Exchangeable Shares for D-Wave Quantum Shares provided for in Section 5.12(3) (the “Automatic Exchange Right”). 

 

	(3)	 In order that the Beneficiaries will be able to participate on a pro rata basis with the holders of D-Wave Quantum Shares in the distribution of assets of D-Wave Quantum in connection with a Liquidation Event, immediately prior to the effective date (the “Liquidation
Event Effective Date”) of a Liquidation Event, each of the then outstanding Exchangeable Shares (other than Exchangeable Shares held by D-Wave Quantum, CallCo and their affiliates) shall be
automatically exchanged for one D-Wave Quantum Share multiplied by the Exchangeable Share Exchange Ratio. To effect such automatic exchange, D-Wave Quantum (or, if D-Wave Quantum so decides, in its sole discretion and to the extent permitted by applicable law, CallCo) shall purchase each such Exchangeable Share outstanding immediately prior to the Liquidation Event Effective
Date, and each Beneficiary shall sell each Exchangeable Share held by it at such time, free and clear of any lien, claim or encumbrance, for a purchase price per share equal to the Exchangeable Share Price immediately prior to the Liquidation Event
Effective Date, which price shall be satisfied in full by D-Wave Quantum or CallCo, as applicable, delivering to such holder the Exchangeable Share Consideration representing such Exchangeable Share Price. For
greater certainty, the Beneficiary shall upon delivery of the Exchangeable Share Consideration cease to have any rights to be paid by ExchangeCo any amount in respect of declared and unpaid dividends on the Exchangeable Shares.

  

	(4)	 The closing of the transaction of purchase and sale contemplated by any exercise of the Automatic Exchange
Right shall be deemed to have occurred at the close of business on the Business Day immediately prior to the Liquidation Event Effective Date, and each Beneficiary shall be deemed to have transferred to D-Wave
Quantum or CallCo, as 

	 	
applicable, all of such Beneficiary’s right, title and interest in and to the Exchangeable Shares held by such Beneficiary free and clear of any lien, claim or encumbrance and the related
interest in the Trust Estate, any right of each such Beneficiary to receive declared and unpaid dividends from ExchangeCo shall be deemed to be satisfied and discharged, and each such Beneficiary shall cease to be a holder of such Exchangeable
Shares and D-Wave Quantum or CallCo, as applicable, shall deliver or cause to be delivered to the Trustee, for delivery to such Beneficiary, the Exchangeable Share Consideration deliverable to such Beneficiary
upon such exercise of the Automatic Exchange Right. Concurrently with each such Beneficiary ceasing to be a holder of Exchangeable Shares, such Beneficiary shall be considered and deemed for all purposes to be the holder of the D-Wave Quantum Shares included in the Exchangeable Share Consideration to be delivered to such Beneficiary and the non-transferable acknowledgements held by such Beneficiary
previously representing the Exchangeable Shares exchanged by the Beneficiary with D-Wave Quantum or CallCo, as applicable, pursuant to the exercise of the Automatic Exchange Right shall thereafter be deemed to
represent the D-Wave Quantum Shares issued to such Beneficiary by D-Wave Quantum or CallCo, as applicable, pursuant to the exercise of the Automatic Exchange Right.

 5.13 Withholding Rights. D-Wave Quantum, CallCo, ExchangeCo, the Trustee and any
other person that has any withholding obligation with respect to any amount paid, deemed paid or otherwise deliverable under this Agreement to any holder of Exchangeable Shares or D-Wave Quantum Shares (any
such person, an “Other Withholding Agent”) shall be entitled to deduct and withhold or direct D-Wave Quantum, CallCo, ExchangeCo, the Trustee or any Other Withholding Agent to deduct or
withhold on their behalf, from any such amounts as D-Wave Quantum, CallCo, ExchangeCo, the Trustee or Other Withholding Agent is required to deduct and withhold with respect to such payment or deemed payment
under the Income Tax Act (Canada) or United States tax laws or any provision of federal, provincial, territorial, state, local, foreign or other tax law, in each case as amended or succeeded. D-Wave
Quantum, CallCo, ExchangeCo, the Trustee and any Other Withholding Agent may act and rely on the advice of counsel with respect to such matters. To the extent that amounts are so deducted and withheld, such deducted or withheld amounts shall be
treated for all purposes as having been paid to the holder of the shares to whom such amounts would otherwise have been paid or deemed paid and such deducted or withheld amounts shall be timely remitted to the appropriate governmental authority as
required by applicable law. To the extent that the amount so required to be deducted or withheld from any payment or deemed payment to a holder exceeds the cash portion of the consideration otherwise payable to the holder (such difference, a
“Withholding Shortfall”), D-Wave Quantum, CallCo, ExchangeCo, the Trustee and any Other Withholding Agent are hereby authorized to sell or otherwise dispose of, or direct D-Wave Quantum, CallCo, ExchangeCo, the Trustee or any Other Withholding Agent to sell or otherwise dispose of, on their account or through a broker (the “Broker”) and on behalf of the relevant
holder, or require such holder to irrevocably direct the sale through a Broker and irrevocably direct the Broker to pay the proceeds of such sale to D-Wave Quantum, CallCo, ExchangeCo, the Trustee and any
Other Withholding Agent, as appropriate (and, in the absence of such irrevocable direction, the holder shall be deemed to have provided such irrevocable direction) such portion of the consideration as is necessary to provide sufficient funds (after
deducting commissions payable to the Broker and other costs and expenses) to D-Wave Quantum, CallCo, ExchangeCo, the Trustee or the Other Withholding Agent, as the case may be, to enable it to comply with such
deduction or withholding requirement and D-Wave Quantum, CallCo, ExchangeCo, the Trustee or the Other Withholding Agent, as the case may be, shall notify the holder thereof and remit to such holder any
unapplied balance of the net proceeds of such sale. Each of D-Wave Quantum, CallCo, ExchangeCo, the Trustee and any Other Withholding Agent, as applicable, shall act in a commercially reasonable manner in

 
respect of any withholding obligation; however, none of D-Wave Quantum, CallCo, ExchangeCo, the Trustee and any Other Withholding Agent, as applicable,
will be liable for any loss arising out of any sale or other disposal of such consideration, including any loss relating to the manner or timing of such sale or other disposal, the prices at which the consideration is sold or otherwise disposed of
or otherwise. 
 5.14 No Fractional Shares. A holder of an Exchangeable Share shall not be entitled to any fraction of a D-Wave Quantum Share upon the exercise of the Exchange Right or Automatic Exchange Right hereunder and such holder otherwise entitled to a fractional interest shall be entitled to receive for such fractional
interest from the Company, D-Wave Quantum or CallCo, as the case may be, a cash payment equal to such fractional interest multiplied by the Current Market Price.

	(2)	 In the exercise of such rights, powers, duties and authorities, the Trustee shall have (and is granted) such
incidental and additional rights, powers, duties and authority not in conflict with any of the provisions of this Agreement as the Trustee, acting in good faith and in the reasonable exercise of its discretion, may deem necessary, appropriate or
desirable to effect the purpose of the Trust. Any exercise of such discretionary rights, powers, duties and authorities by the Trustee shall be final, conclusive and binding upon all persons. For greater certainty, the Trustee shall have only those

	(3)	 The Trustee, in exercising its rights, powers, duties and authorities hereunder, shall act honestly and in good

powers conferred on it hereby unless and until it shall be specifically required to do so under the terms hereof; nor shall the Trustee be required to take any notice of, or to do, or to take any act, action or proceeding as a result of any default
or breach of any provision hereunder, unless and until notified in writing of such default or breach, which notices shall distinctly specify the default or breach desired to be brought to the attention of the Trustee, and in the absence of such
notice the Trustee may for all purposes of this Agreement conclusively assume that no default or breach has been made in the observance or performance of any of the representations, warranties, covenants, agreements or conditions contained herein.

 7.2 Conflict of Interest. If the Trustee has a material conflict of interest in the role of the Trustee as a fiduciary
hereunder and the role of the Trustee in any other capacity, the validity and enforceability of this Agreement shall not be affected in any manner whatsoever by reason only of the existence of such material conflict of interest. If the Trustee
contravenes the foregoing provisions of this Section 7.2, any interested party may apply to the Supreme Court of British Columbia for an order that the Trustee be replaced as Trustee hereunder. 

7.3 Dealings with Transfer Agents, Registrars, etc.

from the records maintained by it which the Trustee may reasonably require for the discharge of its duties and responsibilities under this Agreement.

registrar and transfer agent to comply with all such requests and covenants that it shall supply the Trustee or its transfer agent, as the case may be, in a timely manner with duly executed non-transferable
acknowledgements for the purpose of completing the exercise from time to time of all rights to acquire D-Wave Quantum Shares hereunder, under the Exchangeable Share Provisions and under any other security or
commitment given to the Beneficiaries pursuant thereto, in each case pursuant to the provisions hereof or of the Exchangeable Share Provisions or otherwise. 

7.4 Books and Records. The Trustee shall keep available for inspection during regular business hours by
D-Wave Quantum, CallCo and ExchangeCo at the Trustee’s principal office in Vancouver, British Columbia correct and complete books and records of account relating to the Trust created by, and
Trustee’s actions under, this Agreement, including all relevant data relating to mailings and instructions to and from Beneficiaries and all transactions pursuant to the Exchange Right and the Automatic Exchange Right. On or before March 31,
2023, and on or before March 31 in every year thereafter, so long as the Special Voting Share is registered in the name of the Trustee, the Trustee shall transmit to D-Wave Quantum, CallCo and ExchangeCo a
brief report upon request, dated as of the preceding December 31, with respect to: 
  

	 	(a)	 the property and funds comprising the Trust Estate as of that date; 

 

	 	(b)	 the number of exercises of the Exchange Right, if any, and the aggregate number of Exchangeable Shares received

official, or pursuant to the rules and regulations of any securities exchange or other trading system through which the Exchangeable Shares are traded. In connection therewith, the Trustee may obtain the advice and assistance of such experts or
advisors (who may be experts or advisors to D-Wave Quantum, CallCo and/or ExchangeCo) as the Trustee considers necessary or advisable. If requested by the Trustee,
D-Wave Quantum shall retain or caused to be retained qualified experts or advisors for the purpose of providing such tax advice or assistance. 

 7.6 Indemnification Prior to Certain Actions by Trustee 

 

	(1)	 The Trustee shall exercise any or all of the rights, duties, powers or authorities vested in it by this
Agreement at the request, order or direction of any Beneficiary upon such Beneficiary furnishing to the Trustee reasonable funding, security or indemnity against the costs, expenses and liabilities which may be incurred by the Trustee therein or
thereby, provided that no Beneficiary shall be obligated to furnish to the Trustee any such funding, security or indemnity in connection with the exercise by the Trustee of any of its rights, duties, powers and authorities with respect to the
Special Voting Share pursuant to Article 4, subject to Section 7.15, and with respect to the Exchange Right and the Automatic Exchange Right pursuant to Article 5. 

 

	(2)	 None of the provisions contained in this Agreement shall require the Trustee to expend or risk its own funds or
otherwise incur financial liability in the exercise of any of its rights, powers, duties, or authorities unless funded, given security and indemnified as aforesaid. 

7.7 Action of Beneficiaries. No Beneficiary shall have the right to institute any action, suit or proceeding or to exercise any other remedy
authorized by this Agreement for the purpose of enforcing any of its rights or for the execution of any trust or power hereunder unless the Beneficiary has requested the Trustee to take or institute such action, suit or proceeding and furnished the
Trustee with the funding, security or indemnity referred to in Section 7.6 and the Trustee shall have failed to act within a reasonable time thereafter. In such case, but not otherwise, the Beneficiary shall be entitled to take proceedings in
any court of competent jurisdiction such as the Trustee might have taken; it being understood and intended that no one or more Beneficiaries shall have any right in any manner whatsoever to affect, disturb or prejudice the rights hereby created by
any such action, or to enforce any right hereunder or the Voting Rights, the Exchange Right or the Automatic Exchange Right except subject to the conditions and in the manner herein provided, and that all powers and trusts hereunder shall be
exercised and all proceedings at law shall be instituted, had and maintained by the Trustee, except only as herein provided, and in any event for the equal benefit of all Beneficiaries. 

7.8 Reliance Upon Declarations. The Trustee shall not be considered to be in contravention of any of its rights, powers, duties and authorities
hereunder if, when required, it acts and relies in good faith upon statutory declarations, certificates, opinions or reports furnished pursuant to the provisions hereof or required by the Trustee to be furnished to it in the exercise of its rights,
powers, duties and authorities hereunder if such statutory declarations, certificates, opinions or reports comply with the provisions of Section 7.9, if applicable, and with any other applicable provisions of this Agreement.

Exchange Right or the taking of any other action to be taken by the Trustee at the request or on the application of D-Wave Quantum, CallCo and/or ExchangeCo, and except as otherwise specifically provided
herein, such evidence may consist of a report or opinion of any solicitor, attorney, auditor, accountant, appraiser, valuer or other expert or any other person whose qualifications give authority to a statement made by such person; provided,
however, that if such report or opinion is furnished by a director, officer or employee of D-Wave Quantum, CallCo and/or ExchangeCo it shall be in the form of an Officer’s Certificate or a statutory
declaration. 

  

	(4)	 Each statutory declaration, Officer’s Certificate, opinion or report furnished to the Trustee as evidence
of compliance with a condition provided for in this Agreement shall include a statement by the person giving the evidence: 

  

	 	(a)	 declaring that such person has read and understands the provisions of this Agreement relating to the condition
in question; 

  

	 	(b)	 describing the nature and scope of the examination or investigation upon which such person based the statutory
declaration, certificate, statement or opinion; and 

  

	 	(c)	 declaring that such person has made such examination or investigation as such person believes is necessary to

assistants as may be necessary to the proper discharge of its powers and duties and determination of its rights hereunder and may pay proper and reasonable compensation for all such legal and other advice or assistance as aforesaid;

  

	 	(b)	 employ such agents and other assistants as it may reasonably require for the proper determination and discharge
of its powers and duties hereunder; and 

	 	(c)	 pay reasonable remuneration for all services performed for it (and shall be entitled to receive reasonable
remuneration for all services performed by it) in the discharge of the trusts hereof and compensation for all reasonable disbursements, costs and expenses made or incurred by it in the discharge of its duties hereunder and in the management of the
Trust. 

 7.11 Investment of Moneys Held by Trustee. Unless otherwise provided in this Agreement, any moneys held by or on
behalf of the Trustee which under the terms of this Agreement may or ought to be invested or which may be on deposit with the Trustee or which may be in the hands of the Trustee may be invested or reinvested in the name or under the control of the
Trustee in securities in which, under the laws of the Province of British Columbia, trustees are authorized to invest trust moneys or as otherwise agreed upon in writing by the Trustee and ExchangeCo, provided that such securities are stated to
mature within two years after their purchase by the Trustee and in any event prior to the Sunset Date, and the Trustee shall so invest such money on the written direction of ExchangeCo. Pending the investment of any money as herein provided, such
moneys may be deposited in the name of the Trustee in any chartered bank in Canada or, with the consent of ExchangeCo, in the deposit department of the Trustee or any other specified loan or trust company authorized to accept deposits under the laws
of Canada or any province thereof at the rate of interest then current on similar deposits. The Trustee shall not be held liable for any losses incurred in the investment of any funds as herein provided and all interest on monies held by or on
behalf of the Trustee shall be for the account of ExchangeCo and held by the Trustee for the benefit of ExchangeCo.

7.13 Trustee Not Bound to Act on Request. Except as in this Agreement otherwise specifically provided, the Trustee shall not be bound to act in
accordance with any direction or request of D-Wave Quantum, CallCo and/or ExchangeCo or of the respective directors thereof until a duly authenticated copy of the instrument or resolution containing such
direction or request shall have been delivered to the Trustee, and the Trustee shall be empowered to act upon any such copy purporting to be authenticated and believed by the Trustee, acting reasonably, to be genuine. The Trustee shall have the
right not to act and shall not be liable for refusing to act if, due to a lack of information or for any other reason whatsoever, the Trustee, in its sole judgment, determines that such act might cause it to be in
non-compliance with any applicable anti-money laundering, anti-terrorist or economic sanctions legislation or regulation or guideline. Further, should the Trustee, in its sole judgment, determine at any time
that its acting under this Agreement has resulted in its being in non-compliance with any applicable anti-money laundering or anti-terrorist legislation or regulation, then it shall have the right to resign on
fifteen days written notice to the other parties to this Agreement, provided that (a) the Trustee’s written notice shall describe the circumstances of such non-compliance and (b) if such
circumstances are rectified to the Trustee’s satisfaction within such fifteen day period, such resignation shall not be effective. 
 7.14
Authority to Carry on Business. The Trustee represents to D-Wave Quantum, CallCo and ExchangeCo that, at the date of execution and delivery by it of this Agreement, it is authorized to carry on the
business of a trust company in each of the provinces and territories of Canada but if, notwithstanding the provisions of this Section 7.14, it ceases to be so authorized to carry on business, the validity and enforceability of this Agreement
and the Voting Rights, the Exchange Right and the Automatic Exchange Right and the other rights granted in or resulting from the Trustee being a party to this Agreement shall not be affected in any manner whatsoever

 
by reason only of such event but the Trustee shall, within 90 days after ceasing to be authorized to carry on the business of a trust company in any province or territory of Canada, either become
so authorized or resign in the manner and with the effect specified in Article 10. 
 7.15 Conflicting Claims 

 

	(1)	 If conflicting claims or demands are made or asserted with respect to any interest of any Beneficiary in any
Exchangeable Shares, including any disagreement between the heirs, representatives, successors or assigns succeeding to all or any part of the interest of any Beneficiary in any Exchangeable Shares, resulting in conflicting claims or demands being
made in connection with such interest, then the Trustee shall be entitled, in its sole discretion, to refuse to recognize or to comply with any such claims or demands. In so refusing, the Trustee may elect not to exercise any Voting Rights, Exchange
Right, Automatic Exchange Right or other rights subject to such conflicting claims or demands and, in so doing, the Trustee shall not be or become liable to any person on account of such election or its failure or refusal to comply with any such
conflicting claims or demands. The Trustee shall be entitled to continue to refrain from acting and to refuse to act until: 

  

	 	(a)	 the rights of all adverse claimants with respect to the Voting Rights, Exchange Right, Automatic Exchange Right
or other rights subject to such conflicting claims or demands have been adjudicated by a final judgement of a court of competent jurisdiction and all rights of appeal have expired; or 

 

	 	(b)	 all differences with respect to the Voting Rights, Exchange Right, Automatic Exchange Right or other rights
subject to such conflicting claims or demands have been conclusively settled by a valid written agreement binding on all such adverse claimants, and the Trustee shall have been furnished with an executed copy of such agreement certified to be in
full force and effect. 

  

	(2)	 If the Trustee elects to recognize any claim or comply with any demand made by any such adverse claimant, it
may in its discretion require such claimant to furnish such surety bond or other security satisfactory to the Trustee as it shall deem appropriate to fully indemnify it as between all conflicting claims or demands. 

7.16 Acceptance of Trust. The Trustee hereby accepts the Trust created and provided for, by and in this Agreement and agrees to perform the same
upon the terms and conditions herein set forth and to hold all rights, privileges and benefits conferred hereby and by law in trust for the various persons who shall from time to time be Beneficiaries, subject to all the terms and conditions herein
set forth. 
 7.17 Third Party Interests. Each party to this Agreement hereby represents to the Trustee that any account to be opened by, or
interest to be held by the Trustee in connection with this Agreement, for or to the credit of such party, either (a) is not intended to be used by or on behalf of any third party, or (b) is intended to be used by or on behalf of a third
party, in which case such party hereto agrees to complete and execute forthwith a declaration in the Trustee’s prescribed form as to the particulars of such third party. 

7.18 Privacy. The parties acknowledge that Canadian federal and/or provincial legislation that addresses the protection of individuals’
personal information (collectively, “Privacy Laws”) applies to obligations and activities under this Agreement. Despite any other provision of this Agreement, no party shall take or direct any action that would contravene, or cause
the others 

 
to contravene, applicable Privacy Laws. The parties shall, prior to transferring or causing to be transferred personal information to the Trustee, obtain and retain required consents of the
relevant individuals to the collection, use and disclosure of their personal information, or shall have determined that such consents either have previously been given upon which the parties can rely or are not required under the Privacy Laws.
Specifically, the Trustee agrees (a) to have a designated chief privacy officer, (b) to maintain policies and procedures to protect personal information and to receive and respond to any privacy complaint or inquiry, (c) to use
personal information solely for the purposes of providing its services under or ancillary to this Agreement and not to use it for any purpose except with the consent of or direction from the other parties or the individual involved, (d) not to
sell or otherwise improperly disclose personal information to any third party, and (e) to employ administrative, physical and technological safeguards to reasonably secure and protect personal information against loss, theft, or unauthorized
access, use or modification. The Trustee may transfer personal information to other companies in or outside of Canada for the sole purpose of receiving data processing, storage or other support services in order to facilitate the services provided
under this Agreement. Further, each party agrees that it shall not provide, or cause to be provided to the Trustee, any personal information of any third party to this Agreement other than such personal information as is reasonably necessary to
permit the Trustee to complete its duties hereunder. 
 ARTICLE 8 

COMPENSATION 
 8.1 Fees and
Expenses of the Trustee. D-Wave Quantum, CallCo and ExchangeCo jointly and severally agree to pay the Trustee reasonable compensation for all of the services rendered by it under this Agreement and shall
reimburse the Trustee for all reasonable and documented expenses (including, but not limited to, taxes (other than taxes based on the net income or capital of the Trustee), fees paid to legal counsel and other experts and advisors and agents and
travel expenses) and disbursements, including the reasonable cost and expense of any suit or litigation of any character and any proceedings before any governmental agency, in each case reasonably incurred by the Trustee in connection with its
duties under this Agreement; provided, however, that D-Wave Quantum, CallCo and ExchangeCo shall have no obligation to reimburse the Trustee for any expenses or disbursements paid, incurred or suffered by the
Trustee in any suit or litigation or any such proceedings in which the Trustee is determined to have acted in bad faith or with fraud, gross negligence or willful misconduct. 

ARTICLE 9 

INDEMNIFICATION AND LIMITATION OF LIABILITY 

9.1 Indemnification of the Trustee. 
  

	(1)	 D-Wave Quantum, CallCo and ExchangeCo jointly and severally agree to
indemnify and hold harmless the Trustee and each of its directors, officers, employees and agents appointed and acting in accordance with this Agreement (collectively, the “Indemnified Parties”) against all claims, losses, damages,
reasonable costs, penalties, fines and reasonable and documented expenses (including reasonable and documented expenses of the Trustee’s legal counsel) which, without bad faith, fraud, gross negligence or willful misconduct on the part of any
Indemnified Party, may be paid, incurred or suffered by the Indemnified Party by reason or as a result of the Trustee’s acceptance or administration of the Trust, its compliance with its duties set forth in this Agreement, or any written or
oral instruction delivered to the Trustee by D-Wave Quantum, CallCo or ExchangeCo pursuant hereto. 

	(2)	 The Trustee shall promptly notify D-Wave Quantum, CallCo and ExchangeCo
of a claim or of any action commenced against any Indemnified Parties promptly after the Trustee or any of the Indemnified Parties shall have received written assertion of such a claim or action or have been served with a summons or other first
legal process giving information as to the nature and basis of the claim or action; provided, however, that the omission to so notify D-Wave Quantum, CallCo or ExchangeCo shall not relieve D-Wave Quantum, CallCo or ExchangeCo of any liability which any of them may have to any Indemnified Party except to the extent that any such delay prejudices the defence of any such claim or action or results in any
increase in the liability which D-Wave Quantum, CallCo or ExchangeCo have under this indemnity. Subject to (ii) below, D-Wave Quantum, CallCo and ExchangeCo shall
be entitled to participate at their own expense in the defence and, if D-Wave Quantum, CallCo and ExchangeCo so elect at any time after receipt of such notice, any of them may assume the defence of any suit
brought to enforce any such claim. The Trustee shall have the right to employ separate counsel in any such suit and participate in the defence thereof, but the fees and expenses of such counsel shall be at the expense of the Trustee unless
(i) the employment of such counsel has been authorized by D-Wave Quantum, CallCo or ExchangeCo, or (ii) the named parties to any such suit include both the Trustee and
D-Wave Quantum, CallCo or ExchangeCo and the Trustee shall have been advised by counsel acceptable to D-Wave Quantum, CallCo and ExchangeCo that there may be one or more
legal defences available to the Trustee that are different from or in addition to those available to D-Wave Quantum, CallCo or ExchangeCo and that, in the judgement of such counsel, would present a conflict of
interest were a joint representation to be undertaken (in which case D-Wave Quantum, CallCo and ExchangeCo shall not have the right to assume the defence of such suit on behalf of the Trustee but shall be
liable to pay the reasonable fees and expenses of counsel for the Trustee). This indemnity shall survive the termination of the Trust and the resignation or removal of the Trustee. 

 

	(3)	 Notwithstanding any other provision of this Agreement, any liability of the Trustee shall be limited to:
(i) direct damages; and (ii) in the aggregate, the amount of annual fees collected by the Trustee under this Agreement in the twelve (12) months immediately preceding the first notice of the claim. 

 

	(4)	 Notwithstanding any other provision of this Agreement, and whether such losses or damages are foreseeable or
unforeseeable, the Trustee shall not be liable under any circumstances whatsoever for any special, indirect, incidental, consequential, exemplary, aggravated or punitive losses or damages of any other person. 

9.2 Limitation of Liability. The Trustee shall not be held liable for any loss which may occur by reason of depreciation of the value of any
part of the Trust Estate or any loss incurred on any investment of funds pursuant to this Agreement. 
 ARTICLE 10 

CHANGE OF TRUSTEE 
 10.1
Resignation. The Trustee, or any trustee hereafter appointed, may at any time resign by giving written notice of such resignation to D-Wave Quantum, CallCo and ExchangeCo specifying the date on which it
desires to resign, provided that such notice shall not be given less than 30 days before such desired resignation date unless D-Wave Quantum, CallCo and ExchangeCo otherwise agree and provided further that
such resignation shall not take effect until the date of the appointment of a successor trustee and the acceptance of such appointment by 

 
the successor trustee. Upon receiving such notice of resignation, D-Wave Quantum, CallCo and ExchangeCo shall promptly appoint a successor trustee, which
successor trustee shall be a corporation organized and existing under the laws of Canada and authorized to carry on the business of a trust company in all provinces and territories of Canada, by written instrument in duplicate, one copy of which
shall be delivered to the resigning trustee and one copy to the successor trustee. Failing the appointment and acceptance of a successor trustee, a successor trustee may be appointed by order of a court of competent jurisdiction upon application of
one or more of the parties to this Agreement. If the retiring trustee is the party initiating an application for the appointment of a successor trustee by order of a court of competent jurisdiction, D-Wave
Quantum, CallCo and ExchangeCo shall be jointly and severally liable to reimburse the retiring trustee for its reasonable and documented legal costs and expenses in connection with same. 

10.2 Removal. The Trustee, or any trustee hereafter appointed, may (provided a successor trustee is appointed) be removed at any time on not
less than 30 days’ prior notice by written instrument executed by D-Wave Quantum, CallCo and ExchangeCo, in duplicate, one copy of which shall be delivered to the trustee so removed and one copy to the
successor trustee, provided that such removal shall not take effect until the date of acceptance of appointment by the successor trustee. 
 10.3
Successor Trustee. Any successor trustee appointed as provided under this Agreement shall execute, acknowledge and deliver to D-Wave Quantum, CallCo and ExchangeCo and to its predecessor trustee an
instrument accepting such appointment. Thereupon the resignation or removal of the predecessor trustee shall become effective and such successor trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers,
duties and obligations of its predecessor under this Agreement, with the like effect as if originally named as trustee in this Agreement. However, on the written request of D-Wave Quantum, CallCo and
ExchangeCo or of the successor trustee, the trustee ceasing to act shall, upon payment of any amounts then due to it pursuant to the provisions of this Agreement, execute and deliver an instrument transferring to such successor trustee all the
rights and powers of the trustee so ceasing to act. Upon the request of any such successor trustee, D-Wave Quantum, CallCo, ExchangeCo and such predecessor trustee shall execute any and all instruments in
writing for more fully and certainly vesting in and confirming to such successor trustee all such rights and powers. 
 10.4 Notice of Successor
Trustee. Upon acceptance of appointment by a successor trustee as provided herein, D-Wave Quantum, CallCo and ExchangeCo shall cause to be mailed notice of the succession of such trustee hereunder to each
Beneficiary specified in a then-current List. If D-Wave Quantum, CallCo or ExchangeCo shall fail to cause such notice to be mailed within ten Business Days after acceptance of appointment by the successor
trustee, the successor trustee shall cause such notice to be mailed promptly at the expense of D-Wave Quantum, CallCo and ExchangeCo. 

ARTICLE 11 
 D-WAVE QUANTUM SUCCESSORS 
 11.1 Certain Requirements in Respect of Combination, etc. So long as
any Exchangeable Shares not owned by D-Wave Quantum or its affiliates are outstanding, D-Wave Quantum shall not enter into any transaction (whether by way of
reorganization, consolidation, arrangement, amalgamation, merger, transfer, sale for otherwise) whereby all or substantially all of its undertaking, property and assets would become the property of any other person or, in the

 
case of an amalgamation or merger, of the continuing corporation resulting therefrom, provided that it may do so if: 
  

	 	(a)	 such other person or continuing corporation (the “D-Wave
Quantum Successor”), by operation of law, becomes, without more, bound by the terms and provisions of this Agreement or, if not so bound, executes, prior to or contemporaneously with the consummation of such transaction, a trust agreement
supplemental hereto and such other instruments (if any) as are necessary or advisable to evidence the assumption by the D-Wave Quantum Successor of liability for all moneys payable and property deliverable
hereunder and the covenant of such D-Wave Quantum Successor to pay and deliver or cause to be paid and delivered the same and its agreement to observe and perform all the covenants and obligations of D-Wave Quantum under this Agreement; and 

  

	 	(b)	 such transaction shall be upon such terms and conditions as to substantially preserve and not impair any of the
rights, duties, powers and authorities of the Trustee or the holders of the Exchangeable Shares. 

 11.2 Vesting of Powers in
Successor. Whenever the conditions of Section 11.1 have been duly observed and performed, the parties, if required by Section 11.1, shall execute and deliver the supplemental trust agreement provided for in Section 11.1(a) and
thereupon the D-Wave Quantum Successor and such other person that may then be the issuer of the D-Wave Quantum Shares shall possess and from time to time may exercise
each and every right and power of D-Wave Quantum under this Agreement in the name of D-Wave Quantum or otherwise and any act or proceeding by any provision of this
Agreement required to be done or performed by the board of directors of D-Wave Quantum or any officers of D-Wave Quantum may be done and performed with like force and
effect by the directors or officers of such D-Wave Quantum Successor. 
 11.3 Wholly-Owned Subsidiaries.
Nothing herein shall be construed as preventing (a) the amalgamation or merger of any wholly-owned direct or indirect subsidiary of D-Wave Quantum (other than ExchangeCo or CallCo) with or into D-Wave Quantum, (b) the winding-up, liquidation or dissolution of any wholly-owned direct or indirect subsidiary of D-Wave Quantum
(other than ExchangeCo or CallCo), provided that all of the assets of such subsidiary are transferred to D-Wave Quantum or another wholly-owned direct or indirect subsidiary of
D-Wave Quantum, (c) any other distribution of the assets of any wholly-owned direct or indirect subsidiary of D-Wave Quantum among the shareholders of such
subsidiary for the purpose of winding up its affairs, and (d) any such transactions which are expressly permitted by this Article 11. 
 11.4
Successor Transactions. Notwithstanding the foregoing provisions of this Article 11, in the event of a D-Wave Quantum Extraordinary Transaction: 

 

	 	(a)	 in which D-Wave Quantum merges, combines or amalgamates with, or in
which all or substantially all of the then outstanding D-Wave Quantum Shares are acquired by, one or more other corporations to which D-Wave Quantum is, immediately
before such merger, combination, amalgamation or acquisition, “related” within the meaning of the Income Tax Act (Canada) (otherwise than by virtue of a right referred to in paragraph 251(5)(b) thereof); 

	 	(b)	 which does not result in an acceleration of the Redemption Date in accordance with paragraph (ii) of the
definition of Redemption Date in the Exchangeable Share Provisions; and 

  

	 	(c)	 in which all or substantially all of the then outstanding D-Wave
Quantum Shares are converted into or exchanged for shares or rights to receive such shares (the “Other Shares”) of another corporation (the “Other Corporation”) that, immediately after such D-Wave Quantum Extraordinary Transaction, owns or controls, directly or indirectly, D-Wave Quantum; 

then, (i) all references herein to “D-Wave Quantum” shall thereafter be and be deemed to be references
to “Other Corporation” and all references herein to “D-Wave Quantum Shares” shall thereafter be and be deemed to be references to “Other Shares” (with appropriate adjustments, if
any, as are required to result in a holder of Exchangeable Shares on the exchange, redemption or retraction of such shares pursuant to the Exchangeable Share Provisions or the exchange of such shares pursuant to this Agreement immediately subsequent
to the D-Wave Quantum Extraordinary Transaction being entitled to receive that number of Other Shares equal to the number of Other Shares such holder of Exchangeable Shares would have received if the exchange,
redemption or retraction of such shares pursuant to the Exchangeable Share Provisions or the exchange of such shares pursuant to this Agreement had occurred immediately prior to the D-Wave Quantum
Extraordinary Transaction and the D-Wave Quantum Extraordinary Transaction was completed) but subject to subsequent adjustments to reflect any subsequent changes in the share capital of the issuer of the Other
Shares, including without limitation, any subdivision, consolidation or reduction of share capital, without any need to amend the terms and conditions of this Agreement and without any further action required, and
(ii) D-Wave Quantum shall cause the Other Corporation to deposit one or more voting securities of such Other Corporation to allow Beneficiaries to exercise voting rights in respect of the Other
Corporation substantially similar to those provided for in this Agreement.
