THESE SECURITIES AND THE SECURITIES ISSUABLE UPON EXERCISE HEREOF MAY BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED, DIRECTLY OR INDIRECTLY, ONLY (A) TO XANADU QUANTUM TECHNOLOGIES LIMITED (THE “COMPANY”), (B) OUTSIDE THE UNITED STATES IN COMPLIANCE WITH RULE 904 OF REGULATION S UNDER THE U.S. SECURITIES ACT AND IN COMPLIANCE WITH APPLICABLE LOCAL LAWS AND REGULATIONS, (C) IN COMPLIANCE WITH THE EXEMPTION FROM THE REGISTRATION REQUIREMENTS UNDER THE U.S. SECURITIES ACT PROVIDED BY (I) RULE 144 THEREUNDER IF AVAILABLE OR (II) RULE 144A THEREUNDER, IF AVAILABLE, AND IN EACH CASE IN ACCORDANCE WITH APPLICABLE U.S. STATE SECURITIES LAWS, (D) IN ANOTHER TRANSACTION THAT DOES NOT REQUIRE REGISTRATION UNDER THE U.S. SECURITIES ACT OR ANY APPLICABLE STATE SECURITIES LAWS, OR (E) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE U.S. SECURITIES ACT, PROVIDED THAT, IN THE CASE OF TRANSFERS PURSUANT TO (C)(I) OR (D) ABOVE, THE HOLDER HAS, PRIOR TO SUCH TRANSFER, FURNISHED TO THE COMPANY AN OPINION OF COUNSEL OR OTHER EVIDENCE OF EXEMPTION, IN EITHER CASE REASONABLY SATISFACTORY TO THE COMPANY. DELIVERY OF THIS CERTIFICATE MAY NOT CONSTITUTE “GOOD DELIVERY” IN SETTLEMENT OF TRANSACTIONS ON STOCK EXCHANGES IN CANADA.”

provided that, if any such Warrants and any Class B Subordinate Voting Shares issued on exercise of Warrants are being sold outside the United States in accordance with Rule 903 or 904 of Regulation S under the Securities Act, if available, and in compliance with applicable local securities laws and regulations, the legend set forth above may be removed by providing a declaration to the Company’s registrar and the Warrant agent (if any) to the effect set forth in Schedule “B” hereto together with such documentation as the Company, the Company’s registrar or Warrant agent (if any) may reasonably request; provided, further, that, if any securities are being sold pursuant to Rule 144 under the U.S. Securities Act or with the prior written consent of the Company pursuant to another exemption from registration under the U.S. Securities Act and applicable state securities laws, the legend may be removed by delivery to the Company, the Company’s registrar and to the Warrant agent (if any) of an opinion of counsel, of recognized standing satisfactory in form and substance to the Company, to the effect that such legend is no longer required under applicable requirements of the U.S. Securities Act or state securities laws; and provided, further, that if any such Class B Subordinate Voting Shares are being sold pursuant to an effective registration statement under the U.S. Securities Act (including the Resale Registration Statement (as defined below)), the legend may be removed in accordance with the provisions of Section 9.

“THIS WARRANT MAY NOT BE EXERCISED IN THE UNITED STATES OR BY OR ON BEHALF OF A U.S. PERSON OR A PERSON IN THE UNITED STATES UNLESS THIS WARRANT AND SHARES ISSUABLE UPON EXERCISE OF THIS WARRANT HAVE BEEN REGISTERED UNDER THE U.S. SECURITIES ACT AND THE APPLICABLE SECURITIES LEGISLATION OF ANY SUCH STATE OR EXEMPTIONS FROM SUCH REGISTRATION REQUIREMENTS ARE AVAILABLE. “UNITED STATES” AND “U.S. PERSON” ARE AS DEFINED BY REGULATION S UNDER THE U.S. SECURITIES ACT.”

Subject to Section 2, the Warrants may be exercised in whole or in part at any time and from time to time prior to the Expiry Time. After the Expiry Time, all rights under any outstanding Warrants evidenced hereby, in respect of which the rights of subscription and purchase herein provided for shall not have been exercised, shall wholly cease and terminate and such Warrants shall be void and of no value or effect.

No fractional Class B Subordinate Voting Shares will be issuable upon any exercise of the Warrants and the Holder will not be entitled to any cash payment or compensation in lieu of a fractional Class B Subordinate Voting Share. For greater certainty, if any fractional interest in a Class B Subordinate Voting Share or Warrant would, except for the provisions of this Section 5, be deliverable upon the exercise of this Warrant Certificate, such exercise will be deemed to be for the next smallest whole number of Class B Subordinate Voting Shares or Warrants.

The holding of the Warrants shall not constitute the Holder a shareholder of the Company nor entitle the Holder to any right or interest in respect thereof, except as expressly provided in this Warrant Certificate.

The Company covenants and agrees as follows:

(any of such events in subsections (A), (B), (C) and (D) above being called a “Class B Subordinate Voting Share Reorganization”), the applicable Exercise Price shall be adjusted on the earlier of the record date on which holders of Class B Subordinate Voting Shares are determined for the purposes of the Class B Subordinate Voting Share Reorganization and the effective date of the Class B Subordinate Voting Share Reorganization to the amount determined by multiplying the applicable Exercise Price in effect immediately prior to such record date or effective date, as the case may be, by a fraction:

To the extent that any adjustment in the applicable Exercise Price occurs pursuant to this Section 8(a)(i) as a result of the fixing by the Company of a record date for the distribution of securities exchangeable for or convertible into Class B Subordinate Voting Shares, the applicable Exercise Price shall be readjusted immediately after the expiry of any relevant exchange or conversion right to the applicable Exercise Price which would then be in effect based upon the number of Class B Subordinate Voting Shares actually issued and remaining issuable after such expiry and shall be further readjusted in such manner upon the expiry of any further such right.

If by the terms of the rights, options, or warrants referred to in this Section 8(a)(ii), there is more than one purchase, conversion or exchange price per Class B Subordinate Voting Share, the aggregate price of the total number of additional Class B Subordinate Voting Shares offered for subscription or purchase, or the aggregate conversion or exchange price of the convertible or exchangeable securities so offered, shall be calculated for purposes of the adjustment on the basis of the lowest purchase, conversion or exchange price per Class B Subordinate Voting Share, as the case may be. Any Class B Subordinate Voting Shares owned by or held for the account of the Company shall be deemed not to be outstanding for the purpose of any such calculation. To the extent that any adjustment in the applicable Exercise Price occurs pursuant to this Section 8(a)(ii) as a result of the fixing by the Company of a record date for the issue or distribution of rights, options or warrants referred to in this Section 8(a)(ii), the applicable Exercise Price shall be readjusted immediately after the expiry of any relevant exchange, conversion or exercise right to the applicable Exercise Price which would then be in effect based upon the number of Class B Subordinate Voting Shares actually issued and remaining issuable after such expiry and shall be further readjusted in such manner upon the expiry of any further such right.

and if such issue or distribution does not constitute a Class B Subordinate Voting Share Reorganization or a Rights Offering (any of such non-excluded events being called a “Special Distribution”), the applicable Exercise Price shall be adjusted effective immediately after the record date for the Special Distribution to the amount determined by multiplying the applicable Exercise Price in effect on the record date for the Special Distribution by a fraction:

Any Class B Subordinate Voting Shares owned by or held for the account of the Company shall be deemed not to be outstanding for the purpose of such calculation. To the extent that any adjustment in the applicable Exercise Price occurs pursuant to this Section 8(a)(iii) as a result of the fixing by the Company of a record date for the issue or distribution of rights, options or warrants to acquire Class B Subordinate Voting Shares or securities exchangeable for or convertible into Class B Subordinate Voting Shares referred to in this Section 8(a)(iii), the applicable Exercise Price shall be readjusted immediately after the expiry of any relevant exercise, exchange or conversion right to the amount which would then be in effect based upon the number of Class B Subordinate Voting Shares issued and remaining issuable after such expiry and shall be further readjusted in such manner upon the expiry of any further such right.

(any of such events being called a “Capital Reorganization”), after the effective date of the Capital Reorganization the Holder shall be entitled to receive, and shall accept, for the same aggregate consideration, upon exercise of the Warrants, in lieu of the number of Class B Subordinate Voting Shares to which the Holder was theretofore entitled upon the exercise of the Warrants, the kind and aggregate number of shares and other securities or property resulting from the Capital Reorganization which the Holder would have been entitled to receive as a result of the Capital Reorganization if, on the effective date thereof, the Holder had been the registered holder of the number of Class B Subordinate Voting Shares which the Holder was theretofore entitled to purchase or receive upon the exercise of the Warrants. If necessary, as a result of any such Capital Reorganization, appropriate adjustments shall be made in the application of the provisions of this Warrant Certificate with respect to the rights and interests thereafter of the Holder to the end that the provisions shall thereafter correspondingly be made applicable as nearly as may reasonably be possible in relation to any shares or other securities or property thereafter deliverable upon the exercise of the Warrants.

provided, however, that the Company shall deliver to the Holder an appropriate instrument evidencing the right of the Holder upon the occurrence of the event requiring the adjustment, to an adjustment in the applicable Exercise Price or the number of Class B Subordinate Voting Shares purchasable upon the exercise of the Warrants and to such distribution declared with respect to any such additional Class B Subordinate Voting Shares issuable on the exercise of the Warrants.

As a condition precedent to the taking of any action which would require an adjustment pursuant to Section 8 of this Warrant Certificate, the Company shall take any action which may be necessary in order that the Company has issued and reserved in its authorized capital, and may validly and legally issue as fully paid and non-assessable, all of the Class B Subordinate Voting Shares (or other shares and securities, if applicable) which the Holder of the Warrants is entitled to receive on the exercise hereof.

Upon receipt of evidence satisfactory to the Company of the loss, theft, destruction or mutilation of this Warrant Certificate and, in the case of any such loss, theft or destruction, upon delivery of a bond or indemnity satisfactory to the Company, or, in the case of any such mutilation, upon surrender or cancellation of this Warrant Certificate, the Company will issue to the Holder a new warrant certificate of like tenor, in lieu of this Warrant Certificate, representing the right to subscribe for and purchase the number of Class B Subordinate Voting Shares which may be subscribed for and purchased hereunder.

The Holder and the Company acknowledge that the Warrant to Purchase Non-Voting Common Shares of Xanadu Quantum Technologies Inc. dated May 23, 2023 to purchase 13,999 Non-Voting Common Shares in the capital of Xanadu Quantum Technologies Inc. plus all Additional Shares (as defined in such Warrant) was exchanged for this Warrant Certificate pursuant to a plan of arrangement under Section 182 of the Business Corporations Act (Ontario).

This Warrant Certificate may only be amended with the prior written consent of the Company and the Holder.

If any term or other provision of this Warrant Certificate is invalid, illegal or incapable of being enforced under any applicable law or as a matter of public policy, all other conditions and provisions of this Warrant Certificate shall nevertheless remain in full force and effect. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the Company and the Holder shall negotiate in good faith to modify this Warrant Certificate so as to effect the original intent of the Company and the Holder as closely as possible in a mutually acceptable manner in order that the provisions of this Warrant Certificate be consummated as originally contemplated to the greatest extent possible.

This Warrant Certificate shall be governed by and construed and interpreted in accordance with the laws of the Province of Ontario and the federal laws of Canada applicable therein irrespective of the choice of laws principles.

Subject only to applicable securities laws, the Warrants represented by this Warrant Certificate are transferable by the Holder. The Warrants represented by this Warrant Certificate may be transferred by the Holder completing and delivering to the Company the transfer form attached hereto as Schedule “C”.

This Warrant Certificate and all of its provisions shall enure to the benefit of the Holder and its permitted assigns and successors and shall be binding upon the Company and its successors and permitted assigns.

This Warrant Certificate by electronic means and each of Holder and the Company recognize and accept the use of electronic signatures and records by the other in connection with the execution and storage hereof. To the extent that this Warrant Certificate or any agreement subject to the terms hereof or any amendment hereto is executed, recorded or delivered electronically, it shall be binding to the same extent as though it had been executed on paper with an original ink signature.

All notices, requests, claims, demands and other communications under this Warrant Certificate shall be in writing and shall be given or made (and shall be deemed to have been duly given or made upon receipt) by delivery in person, by overnight courier service, by registered or certified mail (postage prepaid, return receipt requested) or by e-mail to the Holder and the Company at the following addresses (or at such other address as shall be specified in a notice given in accordance with this Section 22):
