Dear Shareholder:

You are cordially invited to attend a special meeting (the “Meeting”) of the shareholders of Fusion Pharmaceuticals Inc., a corporation formed under the federal laws of Canada (“Fusion”), which we will hold virtually on May 29, 2024, at 10 a.m. (Eastern time).

On March 18, 2024, Fusion entered into an Arrangement Agreement with AstraZeneca AB (“Parent”) and 15863210 Canada Inc. (“Purchaser”), a wholly-owned subsidiary of Parent, which provides for the acquisition of Fusion by Purchaser (the “Arrangement Agreement”). Under the terms of the Arrangement Agreement, Purchaser will acquire all of our issued and outstanding common shares for (1) US$21.00 per share in cash pursuant and subject to the terms and conditions of the Arrangement Agreement plus (2) one contingent value right per share representing the contingent right to receive a cash payment equal to US$3.00 per share (the “Milestone Payment”) pursuant and subject to the terms and conditions of the Contingent Value Rights Agreement to be entered into at or prior to the completion of the Arrangement, by and among Parent, Purchaser, and the Rights Agent (as defined therein). The acquisition will be completed by way of a statutory plan of arrangement under the Canada Business Corporations Act (the “Arrangement”).

At the Meeting, shareholders will be asked to consider and vote on a resolution approving the Arrangement, a proposal to ratify an amendment to the bylaws of Fusion and the related proposals described in the enclosed Management Information Circular and Proxy Statement. Our Board of Directors unanimously recommends that shareholders vote “FOR” these proposals, as applicable.

The Management Information Circular and Proxy Statement describes the Arrangement Agreement and the Arrangement and provides detailed information about the Meeting. We encourage you to read the Management Information Circular and Proxy Statement carefully, including the appendices, as it sets forth important information regarding these matters.

Your vote is very important. The Arrangement cannot be completed unless the arrangement resolution is approved by (1) the affirmative vote of at least two-thirds (66²⁄₃%) of the votes cast by shareholders, present in person or represented by proxy at the Meeting, each being entitled to one vote per share of Fusion common shares, and (2) the affirmative vote of a majority of the votes cast by the shareholders in person or represented by proxy at the Meeting, each being entitled to one vote per share of Fusion common shares, after excluding the votes of those persons whose votes are required to be excluded under Multilateral Instrument 61-101 of the Canadian Securities Administrators.

Whether or not you plan to attend the Meeting, we ask you to submit a proxy or voting instruction form to have your shares voted in advance of the Meeting by using one of the methods described in the Management Information Circular and Proxy Statement.

Thank you for your continuing support of Fusion.

Very truly yours,

John F. Valliant, Ph.D.

Director and Chief Executive Officer

Neither the Securities and Exchange Commission nor any state, provincial or territorial securities regulatory agency has approved or disapproved the Arrangement, passed upon the merits or fairness of the Arrangement or passed upon the adequacy or accuracy of the disclosure in this document. Any representation to the contrary is a criminal offense.

The Management Information Circular and Proxy Statement is dated April 25, 2024, and is first being mailed to shareholders on or about April 25, 2024.

NOTICE OF SPECIAL MEETING OF SHAREHOLDERS

To Be Held on May 29, 2024

NOTICE IS HEREBY GIVEN, in accordance with an interim order (the “Interim Order”) of the Ontario Superior Court of Justice (Commercial List) (the “Court”) dated April 24, 2024, that a special meeting (the “Meeting”) of the holders (the “Shareholders”) of common shares (the “Shares”) of Fusion Pharmaceuticals Inc. (“Fusion”) will be held virtually on May 29, 2024 at 10 a.m., Eastern Time. Shareholders as of the close of business on April 16, 2024 (the “Record Date”) and duly appointed proxyholders may attend the Meeting virtually by registering at https://www.proxydocs.com/FUSN, where you will be able to vote electronically and submit questions, subject to the registration procedures set forth below. The Meeting will be held for the following purposes:

to consider, pursuant to the Interim Order, and, if deemed advisable, to pass, with or without variation, a resolution (the “Arrangement Resolution”), the full text of which is set forth in Appendix B to the accompanying Management Information Circular and Proxy Statement of Fusion (the “Circular”), approving a statutory arrangement (the “Arrangement”) pursuant to Section 192 of the Canada Business Corporations Act (the “CBCA”), all as more particularly described in the Circular;

to consider and, if deemed advisable, pass, with or without variation, a resolution confirming Amendment No. 1 to the General Bylaws of Fusion (the “Bylaw Proposal”), as more particularly described in the Circular; and

to transact such other business, including amendments to the foregoing, as may properly be brought before the Meeting or any adjournment or postponement thereof.

As noted above, the Meeting will be a “virtual meeting” of Shareholders, which will be conducted exclusively via the internet. There will not be a physical meeting location, and Shareholders will not be able to attend the Meeting in person. You may attend the Meeting via the internet, vote your Shares during the Meeting and submit questions before the Meeting by registering at https://www.proxydocs.com/FUSN.

In order to attend the Meeting, vote your Shares electronically during the Meeting and submit questions before the Meeting, Shareholders must register in advance at https://www.proxydocs.com/FUSN using the control number located on your proxy card or in the body of the e-mail notification you received. Most of our Shareholders do not hold Shares directly in their own name but instead are non-registered Shareholders who beneficially own Shares that are held by an intermediary, such as their bank, trust company, securities broker, trustee or other nominee (“Beneficial Shareholders”). If you are a Beneficial Shareholder and wish to vote your Shares electronically during the Meeting, you must appoint yourself as your proxyholder following the procedures provided to you by your intermediary and register in advance at https://www.proxydocs.com/FUSN. Upon completing your registration, you will receive further instructions via email, including your unique links that will allow you to access the Meeting and will permit you to submit questions. Further information about how to attend the Meeting, vote your Shares and submit questions is included in the accompanying proxy statement.

Pursuant to the CBCA and the Interim Order, in order for the Arrangement Resolution to become effective, the Arrangement Resolution must be passed by: (1) an affirmative vote of not less than 66²⁄₃% of the votes cast on the Arrangement Resolution by the Shareholders, present in person or represented by proxy at the Meeting, each being entitled to one vote per Share, and (2) an affirmative vote of a majority of the votes cast by the Shareholders present in person or represented by proxy at the Meeting, each being entitled to one vote per Share, after excluding the votes of those persons whose votes are required to be excluded under Multilateral Instrument 61-101 of the Canadian Securities Administrators.

To become effective, the Bylaw Proposal must be approved by an affirmative vote of a majority of the votes cast by Shareholders present in person or represented by proxy at the Meeting, each being entitled to one vote per Share.

This Notice of Special Meeting of Shareholders is accompanied by the Circular, a form of proxy or voting instruction form, as applicable and a form of letter of transmittal (a “Letter of Transmittal”).

A summary of the arrangement agreement among AstraZeneca AB (“Parent”), 15863210 Canada Inc (“Purchaser”) and Fusion dated March 18, 2024 (the “Arrangement Agreement”) and the plan of arrangement (the “Plan of Arrangement”) is included in the Circular, and the full text thereof is attached as Appendix A and Appendix C, respectively, to the Circular and is also available under Fusion’s profile on the System for Electronic Document Analysis and Retrieval (“SEDAR+”) at www.sedarplus.com and on the Electronic Data Gathering, Analysis, and Retrieval system (“EDGAR”) at www.sec.gov/edgar. The full text of the Interim Order is attached as Appendix D to the Circular. Shareholders should carefully review and consider all of the information in the Circular.

Pursuant to and in accordance with the Interim Order and the provisions of Section 190 of the CBCA (as modified or supplemented by the Interim Order, the Plan of Arrangement and any other order of the Court), registered Shareholders have been granted the right to dissent in respect of the Arrangement and, if the Arrangement becomes effective, to be paid an amount equal to the fair value of their Shares (the “Dissent Rights”). Dissent Rights, and the procedures for exercise of Dissent Rights, are described in the Circular under “Dissent Rights”. Failure to comply strictly with the dissent procedures described in the Circular will result in the loss or unavailability of any right to dissent. The dissent procedures require that a registered Shareholder who wishes to exercise Dissent Rights send Fusion a written notice to inform Fusion of his, her or its intention to exercise Dissent Rights, which notice must be received by Fusion at its office located at 270 Longwood Road South, Hamilton, Ontario, Canada, L8P 0A6, Attention: Chief Legal Officer, with a copy to Fusion’s Canadian legal counsel, Osler, Hoskin & Harcourt LLP, 100 King Street West, Suite 6200, P.O. Box 50, Toronto, Ontario, Canada, M5X 1B8, Attention: Alex Gorka and Brett Anderson, not later than 5 p.m. (Eastern time) on the day that is two Business Days immediately preceding the date of the Meeting (as it may be adjourned or postponed from time to time). Beneficial Shareholders who beneficially own Shares registered in the name of an intermediary who wish to dissent should be aware that only registered Shareholders are entitled to dissent. Accordingly, a Beneficial Shareholder desiring to exercise their Dissent Rights must make arrangements for the Shares beneficially owned by such Shareholder to be registered in the Shareholder’s name prior to the time the written objection to the Arrangement Resolution is required to be received by Fusion or, alternatively, make arrangements for the registered holder of such Shares to exercise such right to dissent on the Shareholder’s behalf. It is strongly suggested that any Shareholder wishing to dissent seek independent legal advice, as the failure to comply strictly with the provisions of the CBCA, as modified by the Interim Order and the Plan of Arrangement, may result in the forfeiture of such Shareholder’s right to dissent.

If you are a registered Shareholder and are unable to attend the Meeting, please vote your Shares prior to the Meeting. Instructions on how to vote your Shares are included on the proxy card and in the Circular. If you plan to mail in your vote, it must be completed, signed, dated and returned in accordance with the instructions on the proxy card. If you plan to vote in advance of the Meeting on the Internet, you may vote your Shares by proxy by visiting www.proxypush.com/FUSN. If you plan to vote during the Meeting through the internet, you must register in advance at the site https://www.proxydocs.com/FUSN and log into the virtual meeting platform during

the Meeting using the unique link provided to you via email following the completion of your registration. If you plan to vote by telephone, you can call 1-866-834-5856 and follow the recorded instructions. It is recommended to vote your Shares in advance of the Meeting by following the instructions on https://www.proxypush.com/FUSN. Your proxy is revocable in accordance with the procedures set forth in the Circular.

Your vote is very important, regardless of the number of Shares you own. Whether or not you expect to attend the Meeting, please vote your Shares by proxy in advance of the Meeting to ensure your representation and the presence of a quorum at the Meeting. To ensure that your vote is recorded promptly, please vote as soon as possible, even if you plan to attend the Meeting.

If you are a Beneficial Shareholder, you will receive instructions from the holder of record that you must follow in order to vote your Shares by proxy in advance of the Meeting.

DATED as of the 25^th day of April, 2024

BY ORDER OF THE BOARD OF DIRECTORS

John F. Valliant, Ph.D.

Chief Executive Officer

The Arrangement (page 20)

•

immediately following the Effective Time, Purchaser, a wholly-owned subsidiary of Parent, will acquire all of the issued and outstanding Shares; and

•

each Shareholder (other than Dissenting Shareholders) will be entitled to receive the Consideration in respect of each Share held by such Shareholder.

Upon closing of the Arrangement, Fusion will become a wholly-owned indirect subsidiary of Parent and will apply to cease to be a reporting issuer under applicable Canadian securities laws and to deregister its securities under the Exchange Act as soon as practicable following the completion of the Arrangement and the Common Shares will be delisted from NASDAQ. The Arrangement will be carried out pursuant to the terms of the Arrangement Agreement and the Plan of Arrangement. For information regarding the treatment of Warrants, Restricted Stock Units and Options under the Plan of Arrangement, see the section entitled “The Arrangement—Arrangement Steps”.

The Meeting (page 54)

The Meeting will be held virtually through a live webcast on May 29, 2024 starting at 10 a.m. (Eastern time). There will be no physical meeting location. The format of the virtual Meeting will ensure that Shareholders who attend the Meeting will be afforded comparable rights and opportunities to participate as they would at an in-person meeting. Accordingly, Shareholders that join the webcast of the Meeting will be able to listen and vote regardless of their respective location.

The purpose of the Meeting is for Shareholders to vote upon the Arrangement Resolution. To become effective, the Arrangement Resolution must be approved by: (1) an affirmative vote of not less than 66²⁄₃% of the votes cast on the Arrangement Resolution by Shareholders, present in person or represented by proxy at the Meeting, each being entitled to one vote per Share; and (2) an affirmative vote of a majority of the votes cast by Shareholders present in person or represented by proxy at the Meeting, each being entitled to one vote per Share, after excluding the votes of those Persons whose votes are required to be excluded under MI 61-101.

In addition to the Arrangement Resolution, at the Meeting, holders of Shares also will be asked to consider and vote upon the Bylaw Proposal. In order for the Bylaw Amendment to be confirmed, the Bylaw Proposal must be approved by an affirmative vote of a majority of the votes cast by Shareholders present in person or represented by proxy at the Meeting, each being entitled to one vote per Share.

As of the date of this Circular, we are not currently aware of any other business to come before the Meeting.

Quorum and Record Date (pages 14 and 56)

The Board has fixed the close of business on April 16, 2024 as the Record Date for the determination of Shareholders entitled to receive notice of, and vote at, the Meeting. Only Shareholders will be entitled to receive notice of, and vote at, the Meeting. A quorum for the transaction of business at any meeting of Shareholders is not less than two Persons holding at least 25% of the shares of Fusion entitled to vote at the Meeting present in person or represented by proxy. If a quorum is not present at the time appointed for a Meeting, or within such reasonable time thereafter as the chairperson of the Board or Shareholders present may determine, the chairperson of the Board or Shareholders present may adjourn the meeting to a fixed time and place but may not transact any other business.

Recommendation of the Board and Transaction Committee and Reasons for the Arrangement (page 31)

The Board, after careful review and consideration and consultation with its financial and legal advisors, and upon the unanimous recommendation of the Transaction Committee, unanimously (1) determined that the Arrangement is fair to the Shareholders (other than Parent and its affiliates); (2) determined that the Arrangement is in the best interests of Fusion; and (3) recommends that the Shareholders vote “FOR” the Arrangement Resolution.

For the reasons considered by the Board in reaching its decision to approve the Arrangement Agreement, see the sections entitled “The Arrangement—Recommendation of the Board and Transaction Committee and Reasons for the Arrangement”.

Opinion of Centerview Partners LLC (page 37)

Fusion retained Centerview Partners LLC (“Centerview”) as financial advisor to the Board in connection with the Arrangement and the other transactions contemplated by the Arrangement Agreement and the CVR Agreement (collectively referred to as the “Transaction” throughout this section and the summary of Centerview’s opinion below under the section entitled “The Arrangement—Opinion of Centerview Partners LLC”). In connection with this engagement, the Board requested that Centerview evaluate the fairness, from a financial point of view, to the holders of Shares (other than (1) any Shares held by Parent or any of its affiliates immediately prior to the Effective Time and (2) any Shares held by a Dissenting Shareholder that is ultimately entitled to be paid fair value by Purchaser for its Shares (collectively (1) and (2), the “Excluded Shares”)) of the Consideration proposed to be paid to such holders pursuant to the Arrangement Agreement and the CVR Agreement. Centerview rendered to the Board its oral opinion, which was subsequently confirmed by delivery of a written opinion dated March 18, 2024 that, as of such date and based upon and subject to the various assumptions made, procedures followed, matters considered, and qualifications and limitations upon the review undertaken by Centerview in preparing its opinion, the Consideration proposed to be paid to the holders of Shares (other than Excluded Shares) pursuant to the Arrangement Agreement and the CVR Agreement was fair, from a financial point of view, to such holders.

The full text of Centerview’s written opinion, dated March 18, 2024, which describes the assumptions made, procedures followed, matters considered, and qualifications and limitations upon the review undertaken by Centerview in preparing its opinion, is attached as Appendix E and is incorporated herein by reference. Centerview’s financial advisory services and opinion were provided for the information and assistance of the Board (in their capacity as directors and not in any other capacity) in connection with and for purposes of its consideration of the Transaction and Centerview’s opinion addressed only the fairness, from a financial point of view, as of the date thereof, to the holders of Shares (other than Excluded Shares) of the Consideration to be paid to such holders pursuant to the Arrangement Agreement and the CVR Agreement. Centerview’s opinion did not address any other term or aspect of the Arrangement Agreement, the CVR Agreement or the Transaction and does not constitute a recommendation to any Shareholder or any other person as to how such Shareholder or other person should vote with respect to the Transaction or otherwise act with respect to the Transaction or any other matter.

The full text of Centerview’s written opinion should be read carefully in its entirety for a description of the assumptions made, procedures followed, matters considered, and qualifications and limitations upon the review undertaken by Centerview in preparing its opinion.

Regulatory Approvals (pages 49 and 64)

Under the HSR Act, parties to a transaction that meets certain statutory jurisdictional tests and is not otherwise exempted must provide notice of that transaction to the Antitrust Division of the DOJ (the “Antitrust Division”), and to the FTC, and observe a statutory waiting period before that transaction can close. The Arrangement is subject to these notification and waiting period requirements. On March 22, 2024, the parties submitted to the DOJ and FTC the notifications required under the HSR Act. The statutory waiting period expired at 11:59 p.m. (Eastern time) on April 22, 2024.

Additionally, the Arrangement is conditional on Competition Act Approval as defined in the Arrangement Agreement. Part IX of the Competition Act requires each of the parties to a transaction that exceeds the thresholds set out in Sections 109 and 110 of the Competition Act (a “notifiable transaction”) to provide the Commissioner with prescribed information in respect of the transaction (a “pre-merger notification”). The Arrangement constitutes a notifiable transaction under the Competition Act. On March 28, 2024, the parties filed their respective pre-merger notification filings pursuant to section 114 of the Competition Act and Purchaser submitted a request to the Commissioner for the issuance of an advance ruling certificate, or in the alternative, a

no-action letter. The Arrangement is also conditional on Investment Canada Act Approval as defined in the Arrangement Agreement. Purchaser filed the applicable Investment Canada Act notification on March 25, 2024.

The Arrangement Agreement (page 57)

In the Arrangement Agreement, each of Fusion, Parent and Purchaser has agreed to certain covenants, including customary covenants relating to the operation of Fusion’s business in the ordinary course, to satisfy the conditions precedent to their respective obligations under the Arrangement Agreement and the Plan of Arrangement, and to obtain the regulatory approvals described in the Arrangement Agreement. A copy of the Arrangement Agreement and the Plan of Arrangement are each attached to this Circular as Appendix A and Appendix C, respectively. We urge you to read the full text of the Arrangement Agreement and the Plan of Arrangement because they are the legal documents that govern the Arrangement.

Restrictions on Solicitations of Other Offers (page 69)

Pursuant to the Arrangement Agreement, Fusion has agreed not to:

•

solicit, initiate, knowingly facilitate or knowingly encourage (including by furnishing non-public information or providing copies of, access to, or disclosure of, any confidential information of Fusion or any subsidiary, or enter into any form of agreement, arrangement or understanding) any inquiries or proposals or offers that constitute, or could reasonably be expected to constitute or lead to, an Acquisition Proposal;

•

enter into or otherwise engage or participate in or knowingly encourage any discussions or negotiations with (or provide any information or data to) any Person (other than Parent) with respect to any inquiry, proposal or offer that constitutes, or could reasonably be expected to constitute or lead to, an Acquisition Proposal;

•

make a Change in Recommendation (as further described below); or

•

approve or recommend any Acquisition Proposal or accept, approve, endorse, enter into or recommend, or propose publicly to accept, approve, endorse or recommend, any letter of intent, acquisition agreement, agreement in principle or similar agreement with respect to an Acquisition Proposal.

However, if at any time prior to obtaining the Required Shareholder Approval at the Meeting, Fusion receives an unsolicited bona fide written Acquisition Proposal, Fusion may engage in or participate in discussions or negotiations with the relevant Persons regarding such Acquisition Proposal, and may provide copies of, access to or disclosure of information relating to the assets, properties, facilities, books and records of Fusion or any of its subsidiaries to such person making an Acquisition Proposal (in each case subject to Fusion entering into a customary confidentiality and standstill agreement with such Person having terms at least as onerous in all material respects as those set forth in the Confidentiality Agreement), if, among other things, the Board first determines in good faith, after consultation with its financial and outside legal advisors, that such Acquisition Proposal constitutes or would reasonably be expected to constitute or lead to a Superior Proposal (disregarding any due diligence or access condition to which such Acquisition Proposal is subject).

In addition, the Board may not change its recommendation to Shareholders to vote in favour of the Arrangement Resolution, or cause or permit Fusion to enter into any agreement relating to or providing for an Acquisition Proposal (other than a confidentiality agreement permitted under the Arrangement Agreement). However, if the Board receives an unsolicited bona fide written Acquisition Proposal that constitutes a Superior Proposal, the Board is permitted under certain circumstances to make a Change in Recommendation and/or enter into a definitive agreement with respect to such Superior Proposal, provided that, amongst other conditions Parent has first been provided with the opportunity to match any such Superior Proposal for a period of at least four Business Days.

Conditions to the Arrangement (page 74)

The obligations of Fusion, Parent and Purchaser, as applicable, to consummate the Arrangement are subject to the satisfaction or waiver of certain conditions, including the following:

•

the Arrangement Resolution has been approved and adopted by the Required Shareholder Approval at the Meeting and in accordance with the Interim Order;

•

the Interim Order and the Final Order have each been obtained on terms consistent with the Arrangement Agreement and have not been set aside or modified in a manner unacceptable to Fusion or Parent;

•

the Competition Act Approval, the HSR Approval and the Investment Canada Act Approval have been obtained and are in full force and effect, and have not been rescinded or modified;

•

Interests of Fusion’s Directors and Officers in the Arrangement (page 44)

In considering the recommendation of the Board to vote in favour of the Arrangement Resolution, Shareholders should be aware that certain of Fusion’s directors and executive officers have interests in the

Arrangement that are different from, and/or in addition to, the interests of Shareholders generally. These interests include severance and retention arrangements covering our executive officers, acceleration of unvested equity awards held by our directors and executive officers, and indemnification of our directors and executive officers following the completion of the Arrangement. The Board was aware of and considered these interests, among other matters, in reaching its decision to approve the Arrangement and the Arrangement Agreement. For more information, see “The Arrangement—Interests of Fusion’s Directors and Officer’s in the Arrangement.”

Voting and Support Agreements (pages 52 and 59)

On March 18, 2024, in connection with the execution of the Arrangement Agreement, Perceptive Advisors, LLC, Avidity Master Fund LP, Avidity Private Master Fund I LP, Federated Hermes Kaufmann Fund, Federated Hermes Kaufmann Fund II, Federated Hermes Kaufmann Small Cap Fund, HealthCap VII LP and each director and executive officer of Fusion (collectively, the “Supporting Shareholders”) entered into Voting and Support Agreements with Parent. Under the terms of the Voting and Support Agreements, the Supporting Shareholders have agreed, among other things, to vote their Shares in favour of the approval and authorization of the Arrangement Resolution at the Meeting and, subject to certain exceptions, not to transfer any of their Shares. As of March 18, 2024, the date of the Arrangement Agreement, the Supporting Shareholders beneficially owned an aggregate of approximately 31% of the outstanding Shares entitled to vote at the Meeting. Any Shares of which a Supporting Shareholder acquires beneficial ownership after March 18, 2024, will be subject to the terms and conditions of the Voting and Support Agreement to the same extent as if they were owned by such Supporting Shareholder as of March 18, 2024. The Voting and Support Agreements will terminate upon termination of the Arrangement Agreement and certain other specified events.

Contingent Value Rights Agreement (page 78)

Pursuant to the Arrangement Agreement, at or prior to the Effective Time, Parent, Purchaser and the Rights Agent will enter into the CVR Agreement, in the form included as Exhibit A to Appendix A to this Circular, governing the terms of the CVRs issued pursuant to the Arrangement Agreement. The Rights Agent will keep a register of the holders of CVRs. Holders of CVRs will not be permitted to transfer CVRs (subject to certain limited exceptions).

Each CVR represents the right to receive $3.00, in cash, without interest, subject to any applicable withholding taxes, with such payment conditioned upon the achievement of the following milestone (the “Milestone”) on or prior to August 31, 2029: (1) the submission of a new drug application (an “NDA”) that, if approved, would grant the right to market, distribute and sell any product, in any dosage form, formulation, presentation or package configuration, that contains or comprises, including in combination with any other active ingredient(s), the product candidate referred to by Fusion as of the Effective Time as “FPI-2265” (Ac225-PSMA I&T) (the “Product”) for the treatment of metastatic castration resistant prostate cancer in the United States and (2) the FDA’s confirmation of acceptance of the filing of such NDA, in each case of clauses (1) and (2), in accordance with 21 C.F.R., Part 314.101 or 21 C.F.R. Section 601.2 (as applicable). Such Milestone may be achieved by Parent, Purchaser, any of their permitted assignees, any of their respective affiliates, or any entity that has obtained rights to file an NDA for the Product.

Parent is obligated to use certain specified efforts and resources to achieve the foregoing Milestone until the earlier of achievement or August 31, 2029. However, there can be no assurance that the Milestone will be achieved or that the $3.00 Milestone Payment will be made.

Certain Canadian Federal Income Tax Considerations (page 83)

Shareholders should carefully read the information in this Circular under “Certain Canadian Federal Income Tax Considerations” which qualifies the information set out below and should consult their own tax advisors to determine the particular tax consequences to them of the Arrangement.

Shareholders who are residents of Canada for purposes of the Tax Act will generally realize a taxable disposition of their Shares under the Arrangement. The Canadian income tax consequences in respect of the receipt, holding and disposition of the CVRs, including the tax consequences of the receipt of payment pursuant to the CVRs, are not entirely clear, and Shareholders should carefully read the information in this Circular under the heading “Certain Canadian Federal Income Tax Considerations—Holders Resident in Canada”. Shareholders are urged to consult their own tax advisors having regard to their own particular circumstances.

Shareholders who are not residents of Canada for purposes of the Tax Act and who do not hold their Shares as “taxable Canadian property” (as defined in the Tax Act) will generally not be subject to tax under the Tax Act on the disposition of their Shares under the Arrangement. See “Certain Canadian Federal Income Tax Considerations—Holders Not Resident in Canada”.

Certain U.S. Federal Income Tax Considerations (page 89)

Holders of Shares should read carefully the information in the section entitled “Certain U.S. Federal Income Tax Considerations”, which sets out a general summary of certain U.S. federal income tax considerations that may be relevant to the owners of the Shares that are U.S Shareholders (as defined in such section). Such summary is not intended to be legal or tax advice to any particular Shareholder.

Risks Relating to the Arrangement (page 95)

There are numerous risks relating to the Arrangement, all of which should be carefully considered by Shareholders. A number of the risk factors that Shareholders should consider in connection with the Arrangement are described in the section entitled “Risk Factors”.

Dissent Rights (page 100)

Pursuant to the Plan of Arrangement and the Interim Order, only registered Shareholders may exercise their Dissent Rights in connection with the Arrangement Resolution, pursuant to and in the manner set forth in Section 190 of the CBCA, as modified by the Interim Order and the Plan of Arrangement. There can be no assurance that a Shareholder that dissents will receive consideration for their Shares of value equal to or greater than the Consideration that such Shareholder would have received on completion of the Arrangement if such Shareholder did not exercise their Dissent Rights.

Only registered Shareholders are entitled to dissent. Shareholders should carefully read the section in this Circular titled “Dissent Rights” if they wish to exercise Dissent Rights and seek their own legal advice as failure to strictly comply with the dissent procedures in Section 190 of the CBCA, as modified and supplemented by the Interim Order and the Plan of Arrangement, will result in the loss or unavailability of the right to dissent. See Appendix D and F to this Circular for a copy of the Interim Order and the provisions of Section 190 of the CBCA, respectively. For more information, see the section entitled “Dissent Rights”.

QUESTIONS AND ANSWERS ABOUT THE MEETING AND THE ARRANGEMENT

The following questions and answers are intended to briefly address some commonly asked questions regarding the Arrangement Agreement, the Arrangement and the Meeting. These questions and answers do not address all questions that may be important to you as a Shareholder. Please refer to the section entitled “Summary” and the more detailed information contained elsewhere in this Circular, the appendices to this Circular, and the documents referred to in this Circular, which you should read carefully.

The Arrangement

Q:	*What is this document*?

This document is the Circular that is being sent in advance of the Meeting. This Circular provides information regarding the business of the Meeting, the Arrangement, Fusion, Parent and Purchaser. A form of proxy or voting instruction form, as applicable, and a Letter of Transmittal accompany this Circular. For ease of reference, a glossary of capitalized terms used but not specifically defined in this Circular can be found under the section entitled “Glossary of Terms”.

Q:	*Why is the Meeting being held*?

A:	It is a condition to the completion of the Arrangement that the Arrangement Resolution be approved at the Meeting by:

•

an affirmative vote of not less than 66²⁄₃% of the votes cast on the Arrangement Resolution by the Shareholders, present in person or represented by proxy at the Meeting, each being entitled to one vote per Share; and

•

an affirmative vote of a majority of the votes cast by the Shareholders present in person or represented by proxy at the Meeting, each being entitled to one vote per Share, after excluding the votes of those Persons whose votes are required to be excluded under MI 61-101.

The Meeting is being held so that such approval can be obtained, as well as to vote on the other matters described in the notice for the Meeting and this Circular. These related matters include the Bylaw Proposal, which must be approved by a majority of the votes cast by the Shareholders present in person or represented by proxy at the Meeting, each being entitled to one vote per Share.

Q:	*What is the Arrangement*?

A:	The Arrangement is the transaction contemplated under the Arrangement Agreement entered into by Fusion, Parent and Purchaser under which, among other things:

•

Purchaser, a wholly-owned subsidiary of Parent, will acquire all of the issued and outstanding Shares immediately following the Effective Time; and

•

each Shareholder other than the Dissenting Shareholders will be entitled to receive the Consideration in respect of each Share held by such Shareholder.

On closing of the Arrangement, Fusion will become a wholly-owned indirect subsidiary of Parent and will apply to cease to be a reporting issuer under applicable Canadian securities laws and to deregister its securities under the Exchange Act as soon as practicable following the completion of the Arrangement, and the Shares will be delisted from the NASDAQ. The Arrangement will be carried out pursuant to the terms of the Arrangement Agreement and the Plan of Arrangement. For information regarding the treatment of Warrants, Restricted Stock Units and Options in the Arrangement see the section entitled “The Arrangement—Arrangement Steps”.

Q:	*What will I receive in the Arrangement*?

If the Arrangement is completed, you will be entitled to receive the Consideration in respect of each Share, which is equal to $21.00 in cash per Share and one CVR per Share, subject to applicable withholdings and other source deductions. If you are a registered Shareholder, you must complete and follow the instructions in the Letter of Transmittal to receive the Consideration. If you are a Beneficial Shareholder, you should contact your Intermediary to arrange for your Intermediary to complete the necessary transmittal documents (including the Letter of Transmittal) and make such other arrangements with your Intermediary as are necessary to receive the Consideration.

Q:	*What is a CVR?*

Each CVR is a form of contingent consideration that will entitle the holder thereof to a payment from Purchaser equal to $3.00 per CVR, without interest, subject to any applicable withholding taxes, if the Milestone is achieved by August 31, 2029. If the Milestone is not achieved by such date, no payment will made with respect to the CVR.

Parent is obligated to use certain specified efforts and resources to achieve the Milestone until the earlier of achievement or August 31, 2029. However, there can be no assurance that the Milestone will be achieved or that the $3.00 Milestone Payment will be made.

The right to payment described above is solely a contractual right governed by the terms and conditions of the CVR Agreement. The CVRs will not be evidenced by a certificate or other instrument, will not have any voting or dividend rights, will not represent any equity or ownership interests in Fusion, Parent or Purchaser and will not be transferable except in limited circumstances. No interest will accrue or be payable in respect of any of the amounts that maybe payable in respect of the CVRs. As a holder of a CVR, you will have no greater rights against Parent or Purchaser than those accorded to general, unsecured creditors with respect to the amounts that may be payable with respect to the CVR.

For more information see the section entitled “The Arrangement—CVR Agreement”.

Q:	*What does the Board Recommend*?

For more information, you should also review the sections entitled “The Arrangement—Recommendation of the Board and Transaction Committee and Reasons for the Arrangement”.

Q:	*How do the directors and executive officers of Fusion intend to vote*?

The directors and executive officers of Fusion have each entered into a Voting and Support Agreement with Parent pursuant to which each has agreed to vote or cause to be voted all Shares owned or controlled by them in favour of the Arrangement Resolution. As of March 18, 2024, the date of the Arrangement Agreement, the Shares held by all Supporting Shareholders represent in the aggregate approximately 31% of the outstanding Shares entitled to vote at the Meeting. Any Shares of which a Supporting Shareholder acquires beneficial ownership after March 18, 2024, will be subject to the terms and conditions of the Voting and Support Agreement to the same extent as if they were owned by such Supporting Shareholder as of March 18, 2024.

For more information see the section entitled “The Arrangement —Voting and Support Agreements”.

Q:	*Why is Fusion proposing the Arrangement*?

The Board is proposing the Arrangement because, after consultation with its financial and legal advisors and careful consideration of various factors, and upon the unanimous recommendation of the Transaction Committee, the Board has unanimously determined that the Arrangement is fair to the Shareholders (other than Parent and its affiliates) and that the Arrangement is in the best interests of Fusion.

In reaching these determinations, the Transaction Committee and the Board each considered numerous factors, including, among other things, the potential benefits and risks of the Arrangement and also the elements of the Arrangement which provide protection to Shareholders.

For details regarding the process followed by, and reasons for the recommendation of, the Board, see the sections entitled “The Arrangement —Background of the Arrangement”, “The Arrangement —Recommendation of the Board and Transaction Committee and Reasons for the Arrangement”.

Q:	*When does Fusion expect the Arrangement to be effective*?

The completion of the Arrangement is conditional upon, among other things, receipt of the Required Shareholder Approval, the granting of the Final Order, receipt of the Regulatory Approvals, and such other conditions to completion as set forth in the Arrangement Agreement. Accordingly, the exact timing of completion of the Arrangement cannot be predicted. As required by the terms of the Arrangement Agreement, Fusion is holding the Meeting as soon as reasonably practicable in order to obtain the Required Shareholder Approval of the Arrangement Resolution.

For more information, see the sections entitled “The Arrangement Agreement —Closing Conditions” and “The Arrangement —Covenants—Regulatory Approvals”.

Q:	*Has Fusion received a fairness opinion in connection with the Arrangement*?

Fusion retained Centerview as financial advisor to the Board in connection with the Arrangement and the other transactions contemplated by the Arrangement Agreement and the CVR Agreement. In connection with this engagement, the Board requested that Centerview evaluate the fairness, from a financial point of view, to the holders of Shares (other than Excluded Shares) of the Consideration proposed to be paid to such holders pursuant to the Arrangement Agreement and the CVR Agreement. On March 18, 2024, Centerview rendered to the Board its oral opinion, which was subsequently confirmed by delivery of a written opinion dated March 18, 2024 that, as of such date and based upon and subject to the various assumptions made, procedures followed, matters considered, and qualifications and limitations upon the review undertaken by Centerview in preparing its opinion, the Consideration proposed to be paid to the holders of Shares (other than Excluded Shares) pursuant to the Arrangement Agreement and the CVR Agreement was fair, from a financial point of view, to such holders.

For more information, see the section entitled “The Arrangement —Opinion of Centerview Partners LLC”. The full text of Centerview’s written opinion, dated March 18, 2024, which describes the assumptions made, procedures followed, matters considered, and qualifications and limitations upon the review undertaken by Centerview in preparing its opinion, is attached as Appendix E and is incorporated herein by reference.

Q:	*How will the Arrangement affect my ownership and voting rights as a Shareholder*?

Following the completion of the Arrangement, Shareholders will not have any interest in Fusion or its securities, assets, future revenues or profits. On completion of the Arrangement, it is intended that the Shares will be de-listed from the NASDAQ and Fusion will apply to cease to be a reporting issuer under applicable securities laws as soon as practicable after the Effective Date.

Q:	*What happens if the Arrangement is not completed*?

If the Arrangement is not completed, Shareholders will retain their Shares and will not receive the Consideration. If the Arrangement is not completed, the Shares will continue to be listed for trading on the NASDAQ. Failure to complete the Arrangement may have a material negative effect on the trading price of the Shares. In addition, Shareholders will continue to be subject to the same or similar risks and uncertainties currently facing Fusion and disclosed in Fusion’s Annual Report on Form 10-K for the year ended December 31, 2023 filed with the SEC and available on EDGAR and SEDAR+, as updated by Fusion’s continuous disclosure filings, copies of which are available at www.sec.gov and at www.sedarplus.com.

Beneficial Shareholders — If you plan to vote at the Meeting, print your name in the blank space provided for appointing a proxyholder on the voting instruction form and follow the instructions provided by your Intermediary for mailing your voting instructions. Your Intermediary may allow you to do this online or by telephone instead. Do not complete the voting section because you will vote in real time at the Meeting. You need to act promptly to allow enough time for your Intermediary to receive your instructions and to forward them so that you can register to vote at the Meeting.

•

Register your proxyholder: After you have appointed yourself as proxyholder, you must register in advance at www.proxydocs.com/FUSN.

Q:	*If I change my mind, can I take back my proxy once I have given it*?

A registered Shareholder who has given a proxy may revoke it by depositing an instrument in writing executed by such registered Shareholder or by his or her attorney, authorized in writing, or if the registered Shareholder is a corporate body, under its corporate seal (if applicable) or by an officer or attorney thereof duly authorized, to Fusion’s corporate secretary, by delivery to Fusion Pharmaceuticals Inc., Attn: Corporate Secretary, 270 Longwood Road South, Hamilton, Ontario, Canada L8P 0A6 before the Meeting.

Additionally, a registered Shareholder may revoke a previously provided proxy by logging into the Meeting with its control number and submitting a new proxy at the Meeting, or by timely submitting a later-dated proxy by mail or courier, delivery, telephone or internet. Any votes cast by such registered Shareholder on a ballot at the Meeting will be counted and the previously submitted proxy will be disregarded. If a registered Shareholder does not wish to revoke a previously submitted vote, then they should not vote by ballot at the Meeting.

If you are a Beneficial Shareholder, please contact your Intermediary for instructions on how to revoke your voting instructions.

Q:	*How will my Shares be voted if I give my proxy or voting instruction*?

A:	Your Shares represented by a duly submitted proxy or voting instruction form will be voted at the Meeting by your validly named proxyholder or the named proxyholders in accordance with the instructions you set forth in your completed form of proxy or voting instruction form.

In the absence of such instructions: (a) your validly named proxyholder may decide how to vote your Shares at the Meeting in lieu of the named proxyholders; and (b) if your proxyholder is one of the named proxyholders, such named proxyholder will vote “FOR” the Arrangement Resolution and the other matters set forth in the Notice for the Meeting.

Signing the enclosed form of proxy or voting instruction form gives authority to your validly named proxyholder or the named proxyholders to vote your Shares at the Meeting in accordance with your instructions.

Q:	*What happens if I sell my Shares before completion of the Arrangement*?

A:	If you transfer your Shares, you will have transferred your right to receive the applicable consideration for your Shares in the Arrangement. In order to receive the applicable consideration, you must hold your Shares through completion of the Arrangement.

The Record Date for Shareholders entitled to vote at the Meeting is earlier than the closing of the Arrangement. So, if you transfer your Shares after the Record Date but before the closing of the Arrangement, you will have transferred your right to receive the applicable consideration in the Arrangement, but retained the right to vote at the Meeting.

Q:	*Am I entitled to Dissent Rights*?

A:	Only registered Shareholders are entitled to exercise Dissent Rights with respect to the Arrangement Resolution.

A Beneficial Shareholder desiring to exercise its Dissent Rights must make arrangements for the Shares beneficially owned by such Beneficial Shareholder to be registered in the Beneficial Shareholder’s name prior to the time the written objection to the Arrangement Resolution is required to be received by Fusion or, alternatively, make arrangements for the registered holder of such Shares to dissent on the Beneficial Shareholder’s behalf. A registered Shareholder wishing to exercise Dissent Rights may only dissent with respect to all of the Shares held on behalf of any one Beneficial Shareholder and registered in the name of such Shareholder.

For more information, see the section entitled “Dissent Rights”.

THE ARRANGEMENT

Summary of the Arrangement

Fusion entered into the Arrangement Agreement with Parent and Purchaser on March 18, 2024. A copy of the Arrangement Agreement is attached as Appendix A to this Circular. The Arrangement Agreement provides for the implementation of the Plan of Arrangement pursuant to which, among other things, Shareholders (other than Dissenting Shareholders) will receive the Consideration for each Share, Option, Restricted Stock Unit or Warrant held immediately prior to the Effective Time in accordance with the Plan of Arrangement.

The Arrangement will be implemented by way of a court approved Plan of Arrangement under Section 192 of the CBCA pursuant to the terms of the Arrangement Agreement. Upon completion of the Arrangement, Fusion will become an indirect, wholly-owned subsidiary of Parent.

The principal features of the Arrangement are summarized under the section entitled “Arrangement Steps” below.

The completion of the Arrangement contemplated by the Arrangement Agreement is subject to certain conditions, including, but not limited to, the receipt of the Required Shareholder Approval, the granting of the Final Order, receipt of Regulatory Approvals, and such other conditions to completion as set forth in the Arrangement Agreement.

The Plan of Arrangement is attached to this Circular as Appendix C. We encourage you to read each of the Arrangement Agreement and the Plan of Arrangement in its entirety.

Background of the Arrangement

The Board frequently reviews, with Fusion’s senior management and the assistance of outside advisors, Fusion’s long-term plans and strategic opportunities to increase long-term shareholder value, including accessing the U.S. public markets and seeking partnership and collaboration opportunities to fund the clinical development of its product candidates, the research and development of future product candidates and the possible acquisition of new product candidates. As part of this process, from time to time, Fusion’s senior management has engaged in business development and/or strategic partnering discussions with participants in the biopharmaceutical industry and has regularly reviewed with the Board such potential partnering and collaboration opportunities.

In October 2020, Fusion entered into a collaboration agreement (the “Collaboration Agreement”) with AstraZeneca UK Limited, an affiliate of AstraZeneca (“AstraZeneca UK”) to jointly discover, develop and commercialize next-generation alpha-emitting radioconjugates and combination therapies for the treatment of cancer. Under the collaboration agreement, Fusion and AstraZeneca UK are jointly developing certain pre-clinical and clinical candidates. As a part of their ongoing collaboration, from time to time, members of Fusion’s senior management and representatives of AstraZeneca, including Dr. Susan Galbraith, Executive Vice President, Oncology Research & Development, have discussed the collaboration and more generally non-confidential aspects of Fusion’s and AstraZeneca’s respective businesses.

On August 23, 2023, Fusion entered into a mutual non-disclosure agreement, which included customary non-disclosure provisions, but which did not contain a standstill provision, to facilitate preliminary discussions with a biopharmaceutical company, which we refer to as “Party A”, in connection with the exploration of a potential strategic transaction.

On September 10, 2023, Mohit Rawat, President and Chief Business Officer of Fusion, met with representatives of Party A at the EANM 2023 Congress during which representatives of Party A expressed interest in exploring a potential collaboration or other strategic transaction with Fusion. Discussions between the parties ceased, however, without any proposal being made.

On December 26, 2023, representatives of AstraZeneca contacted Dr. John Valliant, the Chief Executive Officer of Fusion to schedule a meeting during the 2024 JPMorgan Healthcare Conference (the “JPM Conference”).

On January 5, 2024, in connection with the anticipated meeting at the JPM Conference, Fusion and AstraZeneca entered into a mutual non-disclosure agreement which included customary non-disclosure provisions, but which did not contain a standstill provision.

At the JPM Conference, members of senior management of Fusion met numerous third parties to discuss Fusion’s business generally and to determine whether there were potential opportunities for partnership and/or strategic collaborations. As part of those meetings, on January 8, 2024, representatives of senior management of Fusion, including Dr. Valliant, John Crowley, Chief Financial Officer of Fusion and Mr. Rawat met with representatives of AstraZeneca, including Dr. Galbraith, to discuss the current status of the Collaboration Agreement as well as a potential expansion of such collaboration. At the meeting, the representatives of each of Fusion and AstraZeneca agreed to continue exploratory discussions regarding the potential expansion of the Collaboration Agreement. To that end, the parties made arrangements for representatives of AstraZeneca to visit Fusion’s manufacturing site in Hamilton, Ontario later in January 2024. No economic terms of any potential expansion of the existing collaboration or other strategic opportunity were discussed at this meeting.

On January 22, 2024, representatives of AstraZeneca, including Dr. Puja Sapra, Senior Vice President, Biologics Engineering & Oncology Targeted Delivery, and Dr. Dan Freeman, Vice President of Early Development Oncology, both of whom sit on the joint steering committee established in connection with the Collaboration Agreement, met with representatives of Fusion at Fusion’s manufacturing facility in Hamilton,

Ontario during which meeting the representatives of both companies further discussed the Collaboration Agreement and other potential strategic opportunities but not an acquisition of Fusion. No economic terms of any new potential strategic opportunity were discussed at this meeting.

On January 26, 2024, Dr. Galbraith contacted Dr. Valliant via telephone and informed him of AstraZeneca’s interest in exploring a potential acquisition of Fusion and intent to send a non-binding written indication of interest to this effect. Neither party made any proposals during this meeting or otherwise discussed the specific terms or value to be offered in such indication of interest.

Later on January 26, 2024, Dr. Valliant informed Ms. Barbara Duncan, the chairperson of the Board, of these preliminary discussions with Dr. Galbraith. Dr. Valliant also informed representatives of Centerview Partners LLC (“Centerview”) of these preliminary discussions with Dr. Galbraith. The Board had previously identified Centerview as a financial advisor who could provide assistance to Fusion in its evaluation of ongoing strategic matters based on the Board’s and senior management’s previous experience working with Centerview and Centerview’s knowledge and transaction experience in the life sciences sector.

On January 29, 2024, Dr. Valliant and Ms. Duncan discussed via telephone AstraZeneca’s potential interest in proposing an acquisition of Fusion. During this discussion, Dr. Valliant and Ms. Duncan agreed that it would be prudent for Centerview, together with members of Fusion’s senior management team, to contact a limited group of pharmaceutical and biotechnology companies that, based on each company’s strategic fit and financial and administrative capacity, would be most likely to have an interest in pursuing a potential strategic transaction with Fusion. This group of companies consisted of four pharmaceutical and biotechnology companies that had previously expressed general interest in Fusion and its business, including Party A, and three other parties, which we refer to as “Party B”, “Party C” and “Party D”.

On January 30, 2024, Dr. Valliant and Mr. Rawat, met with representatives of Party A to discuss a potential strategic partnership between the two companies. At this meeting, Party A proposed exploring a potential business combination transaction between Party A and Fusion which would likely include significant or all-stock consideration, however no other specific timeline, terms or value to be offered in such transaction was discussed at this meeting or subsequent to it.

On February 2, 2024, Mr. Rawat had a discussion with a representative of Party D regarding Party D’s interest in a potential strategic partnership with Fusion. However, no economic terms of any potential strategic opportunity were discussed at this meeting.

On February 7, 2024, Mr. Rawat and Dr. Eric Hoffman, Senior Vice President, Business Development of Fusion, met with representatives of AstraZeneca as part of a previously scheduled meeting between the collaboration partners, including Dr. Duncan Young, Executive Director, Oncology R&D Business Development, and during this discussion, Dr. Young indicated that a proposal with respect to a potential acquisition of Fusion would be forthcoming.

On February 8, 2024, representatives of Centerview contacted Party B to inquire as to whether Party B would be interested in a potential strategic transaction involving Fusion. Party B indicated that they would like to enter into a confidentiality agreement with Fusion to facilitate the review of certain priority due diligence items to determine their level of interest and whether they would like to proceed with discussions regarding a potential strategic transaction. Following this conversation, representatives of Centerview, at the direction of Fusion, provided a form of confidentiality agreement to Party B.

Also on February 8, 2024, in connection with potential strategic partnership discussions to be held between the parties, Fusion and Party D entered into a mutual non-disclosure agreement, which included customary non-disclosure provisions, but which did not contain a standstill provision.

On February 12, 2024, Mr. Rawat and Dr. Hoffman met with representatives of Party C to discuss a potential collaboration regarding the evaluation of Party C’s pharmaceutical product with a Fusion clinical candidate.

On February 14, 2024, Dr. Galbraith contacted both Dr. Valliant and Mr. Rawat to notify them that AstraZeneca would be delivering a written non-binding offer to acquire Fusion. Following these discussions, representatives of AstraZeneca delivered to Dr. Valliant a written non-binding offer (the “February 14 Proposal”) to acquire Fusion at a price of $20.00 per share in cash. The February 14 Proposal indicated that AstraZeneca was prepared to move expeditiously to complete its due diligence and execute definitive agreements by March 15, 2024, conditioned upon Fusion entering into an exclusivity agreement that granted AstraZeneca exclusivity until 5:00 p.m. (U.S. Eastern Time) on March 14, 2024, which draft exclusivity agreement was provided with the February 14 Proposal.

Later on February 14, 2024, Mr. Pascal Soriot, the Executive Director and Chief Executive Officer of AstraZeneca and Dr. Galbraith contacted Dr. Valliant via telephone to reiterate the offer in the February 14 Proposal and reaffirm AstraZeneca’s continuing interest in a transaction with Fusion.

On February 15, 2024, the Board held a meeting via videoconference, at which members of senior management and representatives of Centerview, Goodwin Procter LLP, Fusion’s outside U.S. legal counsel (“Goodwin”) and Osler, Hoskin & Harcourt LLP, Fusion’s outside Canadian legal counsel (“Osler”), were present. At the meeting, representatives of Goodwin reviewed with members of the Board their fiduciary duties in the context of an offer to acquire Fusion and discussed certain process considerations in the event that the Board decided to engage with AstraZeneca regarding the February 14 Proposal. The representatives of Centerview discussed the terms of the February 14 Proposal. The Board then discussed the February 14 Proposal and potential responses to AstraZeneca, including whether to engage with AstraZeneca with respect to a potential transaction. Following this discussion, the Board directed Centerview to inform AstraZeneca that the February 14 Proposal was inadequate for the Board to grant exclusivity and that AstraZeneca would need to materially improve its offer in order to continue to explore a potential strategic transaction, but directed senior management to continue discussions with AstraZeneca regarding a potential acquisition transaction. The Board also had a discussion regarding whether other pharmaceutical and biotechnology companies might have interest in a potential strategic transaction with Fusion, specifically discussing prior outreach conducted with Party A, B, C and D, and weighing the potential benefits of further outreach to these and other potential counterparties against the potential risks, including the risk of leaks inherent in such a process and the potential impact on Fusion’s business of such leaks. As part of this discussion, the Board considered the prior recent interactions between Fusion’s senior management and other industry participants including Party A, B, C and D. Members of senior management indicated that based on recent discussions with Party A, that Party A indicated that it was still in preliminary stages of considering a potential transaction with Fusion and that such transaction would likely be structured as a stock-for-stock combination if it were to be pursued at all. At the conclusion of this discussion, the Board determined that additional outreach should include only those parties that would be most likely to have interest in Fusion, be able to move decisively and have the ability to consummate a transaction of this size and nature, and therefore, directed Centerview to continue discussions with Party B, Party C and Party D and to also contact an additional pharmaceutical company, which we refer to as “Party E”. Thereafter, following the departure of the representatives of Centerview from the meeting, representatives of Goodwin reviewed with the Board the key terms, including all economic terms, of the proposed formal engagement letter with Centerview as well as Centerview’s customary disclosures regarding Centerview’s prior relationships with Fusion and its affiliates and AstraZeneca. The Board concluded that such relationships would not interfere with Centerview’s ability to provide financial advisory services to Fusion. After discussion, the Board authorized Fusion to execute and deliver the engagement letter with Centerview on the terms presented at the meeting and formally engage Centerview as Fusion’s financial advisor in connection with the review of strategic alternatives. Also at the meeting, the Board determined to form a Transaction Committee of independent directors to (1) manage day-to-day matters related to the transaction process in order to provide an efficient manner in which to actively supervise the process, (2) have the ability to meet as often as needed and direct the process and procedures

related to the review and evaluation of any proposals received by Fusion with respect to a potential strategic transaction, (3) participate in and direct negotiations, (4) consider strategic alternatives (including the status quo) and (5) make a recommendation to the Board regarding the advisability of any such transaction. The Board noted that the Transaction Committee was being formed for expediency of process, and not in response to any actual or potential conflict of interest concerns, and the other members of the Board would be free to participate in any Transaction Committee meetings and the Board reserved the authority to approve any potential strategic transaction. The Transaction Committee consisted of independent directors Pablo Cagnoni, Barbara Duncan and David Meek.

Later on February 15, 2024, Fusion entered into the engagement letter with Centerview.

Also on February 15, 2024, Party B executed a confidentiality agreement with Fusion. The confidentiality agreement with Party B included customary non-disclosure provisions and a standstill provision that prohibited Party B, for an agreed-upon period from the date of the agreement, from offering to acquire or acquiring Fusion, and from taking certain other actions, including soliciting proxies, without the prior consent of Fusion. The confidentiality agreement provided for the termination of the standstill provision upon Fusion’s entry into a definitive agreement with a third party providing for a sale of Fusion, and also allowed Party B to make confidential acquisition proposals to the Board at any time.

Also on February 15, 2024, representatives of Centerview had a telephone call with representatives of Party B, during which the representatives of Party B requested review of certain data as a condition to submitting a preliminary offer to acquire Fusion.

Subsequent to this, as directed by the Board, representatives of Centerview contacted Party C, Party D and Party E to inquire whether Party C, Party D or Party E, as applicable, would be interested in a potential strategic transaction involving Fusion. Party C, Party D and Party E each subsequently indicated that they were not interested in engaging with Fusion at this time with respect to a potential strategic transaction.

On February 17, 2024, Dr. Valliant and Dr. Galbraith had a telephone call during which Dr. Valliant informed Dr. Galbraith that the Board was not prepared to enter into an exclusivity agreement on the basis of the offer set forth in the February 14 Proposal.

On February 19, 2024, Dr. Valliant and Mr. Shaun Grady, Vice President, Business Development Operations of AstraZeneca had a telephone call in which Mr. Grady advised that AstraZeneca would not consider submitting a revised offer, without Fusion first providing a counterproposal.

Later on February 19, 2024, the Board held a meeting via videoconference, at which members of senior management and representatives of Centerview, Goodwin and Osler were present. At the meeting, Dr. Valliant reported to the Board his recent conversations with Dr. Galbraith and Mr. Grady regarding the February 14 Proposal and AstraZeneca’s request that Fusion make a counterproposal. In addition, representatives of Centerview reported on their recent conversations with Party C, Party D and Party E, including that all three parties declined to engage with Fusion with respect to a potential strategic transaction and also reported that Party B would require certain data in advance of making a preliminary acquisition proposal. The Board discussed the commercial risks of sharing such data with Party B and the regulatory risks of a potential acquisition transaction with Party B and based on this information, determined not to proceed further in discussions with Party B. The meeting participants also discussed management’s preliminary long-range plan, including the related methodology, the underlying assumptions and related risks, and the preliminary financial forecasts prepared based on such long-range plan. The Board also discussed and considered Fusion’s standalone prospects generally and its programs for FPI-2265 and Fusion’s other product candidates. Following discussion of these matters, the Board approved the Forecasts (as defined and summarized in the section entitled “Certain Prospective Financial Information”). For a detailed discussion of the Forecasts, please see below under the heading “Certain Prospective Financial Information”. The representatives of Centerview then reviewed certain

preliminary financial analyses related to the February 14 Proposal. The Board then discussed certain potential responses to AstraZeneca regarding its proposal and related process considerations. Following this discussion, the Board authorized Centerview to make a counteroffer to AstraZeneca of $25.00 per share in cash.

On February 20, 2024, at the direction of the Board, the representatives of Centerview contacted Mr. Grady and communicated the Board’s counteroffer.

On February 22, 2024, Mr. Grady contacted Dr. Valliant to preview and discuss the terms of a forthcoming revised offer letter. Following this discussion, representatives of AstraZeneca delivered to Dr. Valliant a written non-binding offer (the “February 22 Proposal”) to acquire Fusion at a price of $21.00 per share in upfront cash, plus a $2.00 per share CVR payable upon achievement of AstraZeneca’s first submission of a new drug application to the FDA for FPI-2265 by a milestone achievement end date of December 31, 2027. The February 22 Proposal was conditioned upon Fusion entering into an exclusivity agreement that granted AstraZeneca exclusivity until 5:00 p.m. (U.S. Eastern Time) on March 14, 2024, which draft exclusivity agreement was provided with the February 22 Proposal.

Later on February 22, 2024, the Board held a meeting via videoconference, at which members of senior management of Fusion and representatives of Centerview, Goodwin and Osler were present. At the meeting, Dr. Valliant reviewed the February 22 Proposal and provided an update on communications with AstraZeneca since the last meeting. Representatives of Centerview reviewed with the Board preliminary financial analyses with respect to February 22 Proposal, including an illustrative risk-adjusted net present value analysis of the CVR based on the assumptions included in the Forecasts. After discussion, the Board determined that the upfront payment and CVR proposed in the February 22 Proposal were still inadequate, but authorized senior management and representatives of Centerview to make a counteroffer to AstraZeneca consisting of (1) an increase in the upfront cash amount to $23.00 and (2) an extension in the milestone achievement end date for the $2.00 per share CVR from December 31, 2027 to June 30, 2028.

On February 23, 2024, at the direction of the Board, the representatives of Centerview contacted Mr. Grady and communicated the Board’s counteroffer.

On February 24, 2024, Mr. Grady contacted Dr. Valliant to preview and discuss the terms of a forthcoming revised offer letter, which Mr. Grady noted was AstraZeneca’s best and final offer. Following this discussion, representatives of AstraZeneca delivered to Dr. Valliant a written non-binding offer (the “February 24 Proposal”) to acquire Fusion at a price of $21.00 per share in upfront cash, plus a $3.00 per share CVR payable upon achievement of the acceptance of AstraZeneca’s first submission of a new drug application to the FDA for FPI-2265 by a milestone achievement end date of August 31, 2028. The February 24 Proposal was conditioned upon Fusion entering into an exclusivity agreement that granted AstraZeneca exclusivity until 5:00 p.m. (U.S. Eastern Time) on March 14, 2024, which draft exclusivity agreement was provided with the February 24 Proposal.

Later on February 24, 2024, the Board held a meeting via videoconference, at which members of senior management and representatives of Centerview, Goodwin and Osler were present. At the meeting, Dr. Valliant updated the Board on discussions with AstraZeneca regarding the February 24 Proposal and reviewed its terms, including the CVR, and the improvement in value over the course of discussions with AstraZeneca. Representatives of Centerview reviewed with the Board preliminary financial analyses with respect to the February 24 Proposal, including an illustrative risk-adjusted net present value analysis of the CVR based on the assumptions included in the Forecasts. Representatives of Osler then reviewed with the members of the Board their fiduciary duties in the context of AstraZeneca’s February 24 Proposal. The Board then discussed the status of discussions with each of the other parties that had been contacted, and that all such parties had either declined to proceed in the process or presented preliminary terms that were not as favorable as a potential transaction with AstraZeneca. After carefully considering the relevant factors, including (1) the Board’s belief that Fusion had obtained AstraZeneca’s best offer, (2) the substantial risk of losing AstraZeneca’s final offer of $21.00 per share

in upfront cash, plus a $3.00 per share CVR if Fusion pursued a higher price or did not reach agreement with AstraZeneca on the timeline specified in the February 24 Proposal and (3) that, based on the fact that each of the other parties that had been contacted in the process declined to submit a proposal, the February 24 Proposal represented the highest price reasonably obtainable by Fusion under the circumstances, the Board directed Dr. Valliant to communicate to Dr. Galbraith that the Board was supportive of the February 24 Proposal, including entering to an exclusivity agreement with AstraZeneca expiring at 5:00 p.m. (U.S. Eastern Time) on March 14, 2024, and also authorized representatives of Centerview to inform AstraZeneca of the Board’s decision.

Following the meeting, on February 24, 2024, representatives of Centerview delivered to representatives of AstraZeneca a draft non-disclosure agreement, including a standstill provision, which would supersede the non-disclosure agreement entered into between the parties on January 5, 2024, together with a revised draft of the exclusivity agreement.

On February 26, 2024, Fusion provided representatives of AstraZeneca and its advisors with access to comprehensive due diligence materials in Fusion’s data room, and over the course of the following weeks, senior management and the advisors of each of Fusion and AstraZeneca discussed and exchanged additional due diligence information. Fusion also organized a number of due diligence calls among the parties and their advisors to discuss numerous customary diligence matters.

Also, on February 26, 2024, representatives of Goodwin delivered an initial draft of the arrangement agreement to Freshfields Bruckhaus Deringer US LLP, AstraZeneca’s outside U.S. legal counsel (“Freshfields”), which provided, among other things, (1) for the transaction to be implemented through a court approved plan of arrangement under Canadian law, (2) customary conditions to consummate the plan of arrangement, including U.S. and Canadian antitrust approvals, (3) an obligation on the part of Parent to use reasonable best efforts to obtain antitrust approval, including undertaking certain remedial actions such as divestitures, and a reverse termination fee payable by Parent related to failure to obtain such antitrust approvals and (4) a termination fee equal to 2.5% of the aggregate upfront cash transaction equity value in the transaction, payable by Fusion to Parent upon the termination of the Arrangement Agreement under certain circumstances, including to accept and enter into a definitive agreement with respect to an unsolicited superior offer (the “Corporation Termination Fee”).

On February 29, 2024, Fusion and AstraZeneca entered into a mutual non-disclosure agreement, which superseded the mutual non-disclosure agreement that the parties entered into on January 5, 2024, and included customary non-disclosure provisions and a standstill provision that prohibited AstraZeneca, for an agreed-upon period from the date of the agreement, from offering to acquire or acquiring Fusion, and from taking certain other actions, including soliciting proxies, without the prior consent of Fusion. The non-disclosure agreement provided for the termination of the standstill provision upon Fusion’s entry into a definitive agreement with a third party providing for a sale of Fusion, and also allowed AstraZeneca to make confidential acquisition proposals to the Board at any time. Fusion and AstraZeneca also entered into an exclusivity agreement providing for exclusive negotiations between the parties until the first to occur of (1) the execution of a definitive acquisition agreement between the parties with respect to the proposed transaction, (2) 5:00 p.m. (U.S. Eastern Time) on March 14, 2024, and (3) the time at which AstraZeneca reduces, or proposes a reduction in, the February 24 Proposal purchase price of $21.00 per share in upfront cash, plus a $3.00 per share CVR, including any reduction in the $21.00 per share in upfront cash.

Also, on February 29, 2024, representatives of Goodwin delivered an initial draft of the disclosure letter to Freshfields.

On March 4, 2024, representatives of Freshfields provided an initial draft of the CVR agreement to Goodwin. Thereafter, during the period between March 4 until March 18, representatives of Goodwin and Osler, on behalf of Fusion, and representatives of Freshfields and Blake, Cassels & Graydon LLP, AstraZeneca’s

outside Canadian legal counsel (“Blakes”), on behalf of AstraZeneca, conducted a number of conference calls and exchanged drafts of the CVR agreement. Among other items, the parties discussed and negotiated (1) the definition of the milestone, (2) the outside date for Parent’s obligation to achieve the milestone, and (3) the commercially reasonable efforts standard that Parent is obligated to take to achieve the milestone.

On March 5, 2024, representatives of Freshfields sent a revised draft of the arrangement agreement to Goodwin, that, among other things, (1) accepted the transaction structure proposed by Fusion in its draft Arrangement Agreement, including triggers for payment of the Corporation Termination Fee (but proposing that the fee equal 4% of the aggregate upfront cash transaction equity value in the transaction), (2) removed the affirmative requirement for Parent to undertake any divestitures or take certain other remedial actions in order to obtain U.S. and Canadian antitrust approvals, (3) proposed a reverse termination fee equal to 4% of the aggregate upfront cash transaction equity value, which reverse termination fee would be payable by Parent to Fusion in the event of a termination of the Arrangement Agreement as a result of certain conditions related to the receipt of applicable antitrust approvals not being satisfied and (4) proposed that certain directors, officers and unspecified significant shareholders execute voting and support agreements in favor of the Arrangement.

Thereafter, during the period between March 5 until March 18, representatives of Goodwin and Osler, on behalf of Fusion, and representatives of Freshfields and Blakes, on behalf of AstraZeneca, conducted a number of conference calls and exchanged drafts of the arrangement agreement and drafts of the corresponding disclosure letter. Among other items, the parties negotiated (1) the definition of “Company Material Adverse Effect”, which generally defines the standard for closing risk, (2) Fusion’s representations, warranties and interim operating covenants, (3) the provisions relating to the rights of the Board to change its recommendation to shareholders with respect to the transaction with AstraZeneca and to accept a “superior proposal”, (4) the efforts required by Parent to obtain required regulatory approvals, (5) the amount and terms of the Corporation Termination Fee payable in the event that Fusion were to terminate the arrangement agreement to accept a superior proposal and in certain other related circumstances, (6) the amount and terms of the reverse termination fee payable by Parent in the event Parent or Fusion were to terminate the arrangement agreement for failure to obtain the required regulatory approvals prior to the Outside Date, (7) the request by AstraZeneca for certain directors, officers and significant shareholders to execute voting and support agreements in favor of the Arrangement and (8) the covenants regarding employee benefit matters applicable to Fusion’s employees. In addition, representatives of Fusion and AstraZeneca negotiated a transaction bonus pool and severance guidelines for non-executive employees to be honored by AstraZeneca.

On March 8, 2024, the Transaction Committee held a meeting via videoconference at which members of senior management and representatives of Centerview, Goodwin and Osler were present. At the meeting, representatives of Goodwin provided an overview of the initial draft CVR agreement received from representatives of Freshfields and Blakes and the related areas of negotiation, including (1) requesting a later outside date for Parent’s obligation to achieve the milestone and (2) seeking a commercially reasonable efforts standard that Parent is obligated to take to achieve the milestone and also discussed the status of negotiations on certain employee compensation matters, including AstraZeneca’s request for retention agreements to be entered into concurrently with execution of the arrangement agreement with Dr. Valliant and Dr. Burak. In addition, representatives of Centerview provided a report on the status of AstraZeneca’s due diligence process, which was substantially complete. Representatives of Goodwin then reviewed the potential timeline to signing and announcement of the transaction and expected next steps.

On March 10, 2024, Dr. Galbraith contacted Dr. Valliant via telephone to inform Dr. Valliant of AstraZeneca’s request for Dr. Valliant and Dr. Eric Burak, Chief Technology Officer of Fusion, to remain employed with Fusion following the closing of the transactions contemplated by the Arrangement Agreement (the “Closing”) and to enter into retention agreements with AstraZeneca in connection therewith concurrently with announcement that would become effective upon the closing of the Arrangement. No form of retention agreements or any terms were provided or discussed at this time.

On March 12, 2024, Dr. Valliant and Dr. Galbraith had a telephone call to discuss the progression of the negotiations of the arrangement agreement and CVR agreement. During this call, Dr. Galbraith raised to possibility of extending the exclusivity period to allow for additional time to finalize the definitive documentation and accommodate AstraZeneca’s scheduled board meeting on March 18, 2024, which Dr. Valliant noted and indicated that he would discuss with the Board.

Later on March 12, 2024, the Transaction Committee held a meeting via videoconference at which members of senior management and representatives of Centerview, Goodwin and Osler were present. At the meeting, representatives of Goodwin provided an update on key transaction negotiation points, including an overview of the draft CVR agreement received from AstraZeneca’s counsel and the related areas of negotiation, including (1) the outside date for Parent’s obligation to achieve the milestone, (2) the commercially reasonable efforts standard that Parent is obligated to take to achieve the milestone, (3) AstraZeneca’s request for retention agreements to be entered into concurrently with execution of the arrangement agreement with Dr. Valliant and Dr. Burak and (4) AstraZeneca’s request that voting and support agreements be obtained from certain unspecified significant shareholders of Fusion concurrently with the execution of the Arrangement Agreement. In addition, Dr. Valliant reported on his recent conversation with Dr. Galbraith during which Dr. Galbraith raised the possibility of extending the exclusivity period to allow for additional time to finalize the definitive agreements and accommodate AstraZeneca’s scheduled board meeting to consider, and potentially approve the transaction on March 18, 2024. The Transaction Committee discussed next steps and agreed that representatives of Fusion and AstraZeneca should have additional conversations regarding the open areas of negotiation.

Also, on March 12, 2024, Freshfields sent an initial draft voting and support agreement to Goodwin, which provided that certain significant shareholders would agree to vote their Shares in support of the Arrangement. Thereafter, from March 12 to March 17, representatives of Goodwin and Osler, on behalf of Fusion, and representatives of Freshfields and Blakes, on behalf of AstraZeneca, conducted a number of conference calls and exchanged drafts of the voting and support agreement.

In addition, on March 12, 2024, representatives of AstraZeneca sent each of Dr. Valliant and Dr. Burak an initial draft of their respective retention agreements. Over the course of March 12 until March 16, Dr. Valliant and Dr. Burak and their respective counsel reviewed their respective retention agreements, and concurrently with the execution of the Arrangement Agreement on March 18, 2024, each of Dr. Valliant and Dr. Burak executed and delivered retention agreements to AstraZeneca.

On March 13, 2024, Dr. Valliant and Mr. Grady discussed, among other things, (1) the status of internal AstraZeneca governance processes, (2) open negotiation points, (3) certain due diligence findings, and (4) the status of AstraZeneca’s request for retention agreements to be entered into concurrently with execution of the arrangement agreement with Dr. Valliant and Dr. Burak. Mr. Grady requested that the Board consider extending the exclusivity period to 5:00 p.m. (U.S. Eastern Time) on March 18, 2024, which Dr. Valliant noted and indicated that he would discuss with the Board.

On March 14, 2024, the Board held a meeting via videoconference, at which members of senior management and representatives of Centerview, Goodwin and Osler, were present. At the meeting, Dr. Valliant reported on his recent conversation with Mr. Grady regarding AstraZeneca’s request for an extension of the exclusivity period until 5:00 p.m. (U.S. Eastern Time) on March 18, 2024 to allow for additional time to finalize the definitive agreements and accommodate AstraZeneca’s scheduled board meeting on March 18, 2024. In addition, Dr. Valliant provided an update on the open negotiation points in the arrangement agreement and CVR agreement, including (1) the outside date for Parent’s obligation to achieve the milestone, (2) the commercially reasonable efforts standard that Parent is obligated to take to achieve the milestone, (3) AstraZeneca’s request for retention agreements to be entered into concurrently with execution of the arrangement agreement with Dr. Valliant and Dr. Burak and (4) that voting and support agreements would be obtained from certain significant shareholders of Fusion. Following discussion of the open negotiation points and considering the risk of potential leaks and extended timeline of the potential transaction with AstraZeneca, the Board directed Dr. Valliant to

inform AstraZeneca that Fusion would not request voting and support agreements from any of its significant shareholders. The Board discussed the request to extend the exclusivity period and in light of the status of the remaining negotiation points in the arrangement agreement and CVR agreement, the Board authorized senior management to only enter into a letter agreement to extend the exclusivity period until 5:00 p.m. (U.S. Eastern Time) on March 18, 2024 upon the satisfactory resolution of such remaining negotiation points.

On March 15, 2024, Mr. Grady and Dr. Valliant discussed via telephone certain open negotiation points. During this discussion, Mr. Grady informed Dr. Valliant that, as a condition to the execution of the arrangement agreement, AstraZeneca would require that Fusion obtain voting and support agreements from certain significant shareholders prior to its board meeting on March 18, 2024. Mr. Grady subsequently informed representatives of Centerview of the same condition.

Later on March 15, 2024, the Board held a meeting via videoconference, at which members of senior management and representatives of Centerview, Goodwin and Osler were present. At the meeting, Dr. Valliant and representatives of Centerview reported on their respective conversations with representatives of AstraZeneca regarding their request to obtain voting and support agreements from certain significant shareholders prior to March 18, 2024. The Board discussed the process for outreach to the significant shareholders and following this discussion, the Board authorized senior management to contact each of the significant shareholders, subject first to execution of a confidentiality agreement, and use reasonable efforts to obtain voting and support agreements from such shareholders.

Following the meeting, after market close on March 15, 2024, members of senior management of Fusion contacted each of the significant shareholders, and subject to execution of a confidentiality agreement, discussed and negotiated a voting and support agreement to be entered into concurrently with the execution of the Arrangement Agreement.

On March 17, 2024, representatives of Freshfields sent a draft letter agreement, which provided for the extension of the exclusivity period until 5:00 p.m. (U.S. Eastern Time) on March 18, 2024.

On March 18, 2024, representatives of Goodwin, Osler, Freshfields and Blakes finalized the open items in the transaction documentation, including the Arrangement Agreement, the CVR Agreement and the Voting and Support Agreement.

Later on March 18, 2024, the Transaction Committee, the Compensation Committee and the Board held a joint meeting via videoconference, at which members of senior management and representatives of Centerview, Goodwin and Osler, were present, to consider approval of the proposed transaction with AstraZeneca. At the meeting, representatives of Centerview reviewed with the Board, including all members of the Transaction Committee, Centerview’s financial analysis of the Consideration, and rendered to the Board, including all members of the Transaction Committee, an oral opinion, which was subsequently confirmed by delivery of a written opinion dated March 18, 2024 that, as of such date and based upon and subject to various assumptions made, procedures followed, matters considered, and qualifications and limitations upon the review undertaken by Centerview in preparing its opinion, the Consideration to be paid to the holder of Shares (other than as specified in such opinion) pursuant to the Arrangement Agreement and the CVR Agreement was fair, from a financial point of view, to such holders, as more fully described below under the section entitled “Opinion of Centerview Partners LLC.” Representatives of Osler reviewed the fiduciary duties of the Board in this context. Representatives of Goodwin then reviewed the terms of the final proposed Arrangement Agreement, CVR Agreement and Voting and Support Agreement with Parent and Purchaser. Following additional discussion and consideration of the Arrangement Agreement, the Arrangement and the other transactions contemplated by the Arrangement Agreement, including the CVR Agreement (including the factors described in the section entitled “Reasons for the Arrangement”), the Transaction Committee unanimously adopted resolutions: (1) determining that the Arrangement was in the best interests of Fusion and the Consideration was fair to the Shareholders (other than Parent and its affiliates), (2) recommending to the Board that Fusion enter into the Arrangement Agreement and (3) recommending to the Board that the Board recommend that the Shareholders vote in favor of the

Arrangement Resolution. Thereafter, the Compensation Committee adopted resolutions approving various compensation arrangements. Thereafter, the Board, based upon the unanimous recommendation of the Transaction Committee, adopted resolutions: (1) determining that the Arrangement was in the best interests of Fusion and the Consideration was fair to the Shareholders (other than Parent and its affiliates), (2) approving the Arrangement Agreement, the Arrangement, the CVR Agreement and Fusion’s performance of its obligations under the Arrangement Agreement, (3) recommending that the Shareholders vote in favor of the Arrangement Resolution and (4) approving the amendment to the bylaws to change the exclusive forum for securities law claims to the U.S. District Court for the District of Delaware.

Later during the evening of March 18, 2024, Fusion, Parent and the Purchaser executed and delivered the Arrangement Agreement (which included as an exhibit the form of the CVR Agreement), and contemporaneously therewith, the Voting and Support Agreements and Retention Agreements were each executed and delivered by the parties thereto.

Thereafter, in the early hours of the day in New York and London, before the opening of trading of the United Kingdom and United States stock markets on March 19, 2024, Fusion and AstraZeneca each issued a press release announcing the execution and delivery of the Arrangement Agreement.

Recommendation of the Board and Transaction Committee and Reasons for the Arrangement

In evaluating the Arrangement Agreement and the transactions contemplated by the Arrangement Agreement, including the Arrangement, each of the Transaction Committee and the Board consulted with Fusion’s senior management and legal and financial advisors. In the course of reaching its determination that the terms of the Arrangement are fair to the Shareholders and in the best interests of Fusion and to recommend that the Shareholders vote in favor of the Arrangement Resolution, each of the Transaction Committee and the Board reviewed, evaluated, and considered a significant amount of information and numerous factors and benefits of the Arrangement, each of which the Transaction Committee and the Board believed supported its determination and recommendation. As a result, for the reasons set forth below, the Board unanimously recommends, upon the unanimous recommendation of the Transaction Committee, that the Shareholders vote in favor of the Arrangement Resolution:

Premium to Market Price. Each of the Transaction Committee and the Board considered:

•

the historical market prices, volatility and trading information with respect to the Shares; and

•

the recent historical trading prices of the Shares on NASDAQ, as compared to the Consideration, including the fact that

•

(1) the upfront Cash Consideration represents:

•

a 97% premium to the closing price of $10.64 on March 18, 2024, the last trading day before the public announcement of the Arrangement Agreement;

•

an 85% premium to the trailing volume-weighted average price of $11.37 for the 30-day period ended on March 18, 2024; and

•

a 106% premium to the trailing volume-weighted average price of $10.17 for the 60-day period ended on March 18, 2024;

•

(2) the aggregate Consideration represents:

•

a 126% premium to the closing price of $10.64 on March 18, 2024, the last trading day before the public announcement of the Arrangement Agreement;

•

a 111% premium to the trailing volume-weighted average price of $11.37 for the 30-day period ended on March 18, 2024; and

•

a 136% premium to the trailing volume-weighted average price of $10.17 for the 60-day period ended on March 18, 2024.

Certainty of Upfront Value. Each of the Transaction Committee and the Board considered that the consideration to be paid in the Arrangement will consist primarily of upfront cash, which provides liquidity and certainty of value to the Shareholders. Taking into account the various risks that Fusion would face by continuing to pursue its current business and financial plans, each of the Transaction Committee and the Board believed that this certainty of value was compelling compared to the uncertain long-term value creation potential of Fusion’s business.

Opportunity to Realize Additional Value. Each of the Transaction Committee and the Board considered the fact that, in addition to the Cash Consideration, the Shareholders have an opportunity to realize additional value if the Milestone set forth in the CVR Agreement is achieved within the time period prescribed therein, through an additional cash payment of $3.00 per CVR. Each of the Transaction Committee and the Board considered that Parent and its affiliates (i) are obligated to use commercially reasonable efforts to achieve the milestone until August 31, 2029 and (ii) have extensive resources, capabilities and experience in biopharmaceutical product late-stage development and commercialization, particularly as such experience, capabilities and resources relate to the potential achievement of the milestone, allowing for the potential to significantly accelerate FPI-2265 regulatory approval compared to Fusion’s standalone capabilities.

Fusion’s Operating and Financial Condition and Prospects. Each of the Transaction Committee and the Board considered Fusion’s operating and financial performance and its prospects, including certain financial forecasts for Fusion prepared by Fusion’s management, which reflect an application of various assumptions of management, as further discussed below under the heading titled “Certain Prospective Financial Information”. Each of the Transaction Committee and the Board considered Fusion’s business and financial plans, including the risks and uncertainties associated with achieving and executing on Fusion’s business and financial plans in the short- and long-term, as well as the general risks of market conditions that could reduce the price of the Shares. Among the potential risks and uncertainties identified by the Transaction Committee and the Board were:

•

the challenges associated with Fusion’s need for additional capital to support the development and commercialization of FPI-2265 and its other pipeline product candidates, taking into account the current financing environment for biopharmaceutical companies, the uncertainty that Fusion would be able to raise sufficient cash to fund its business through to positive cash flow and the significant associated dilution that would be experienced by the Shareholders if Fusion were to sell significant additional Shares;

•

the fact that Fusion may not be able to achieve profitability;

•

the significant risks, challenges and uncertainties associated with continued development and regulatory approval efforts with respect to FPI-2265, including the challenges associated with designing and conducting future clinical trials for FPI-2265, the outcome of which is inherently uncertain and may not support regulatory approval and the challenges associated with obtaining approvals from regulatory authorities, which can take years to complete and the receipt of which are not guaranteed;

•

the challenges faced by the biopharmaceutical industry, which could impact Fusion, including macroeconomic trends and the fact that the industry is subject to complex regulatory and political

regimes and evolving pricing environment, particularly with respect to generating revenue and profitability in light of the increasing scrutiny of pharmaceutical pricing and proposals to address the perceived high cost of pharmaceuticals;

•

achieving Fusion’s growth plans in light of the current and foreseeable market conditions, including the risks and uncertainties in the U.S. and global economy generally and the biopharmaceutical industry generally;

•

assuming Fusion was successful in commercializing any product candidate, Fusion’s ability to achieve revenue growth in the future and improve profitability and the execution risks of achieving those goals; and

•

other risks and uncertainties discussed in Fusion’s public filings with the SEC.

Potential Strategic Alternatives. Each of the Transaction Committee and the Board reviewed the possible alternatives to the Arrangement, including the possibility of continuing to operate Fusion as an independent company, the potential benefits and risks of these alternatives to Fusion and its Shareholders and the timing and likelihood of effecting such alternatives. Taking into account the risks of execution as well as business, competitive, industry and market risks, each of the Transaction Committee and the Board considered that none of the possible alternatives were reasonably likely to present superior opportunities for Fusion to create greater value for the Shareholders.

Negotiation Process. Each of the Transaction Committee and the Board considered the fact that the terms of the Arrangement Agreement were the result of robust arm’s-length negotiations conducted by Fusion with the knowledge and at the direction of the Board (including through the Transaction Committee) and with the assistance of its financial and legal advisors. Each of the Transaction Committee and the Board also considered the enhancements that Fusion and its advisors were able to obtain as a result of robust arm’s-length negotiations with AstraZeneca, including the increase in the valuation offered by AstraZeneca from the time of its initial expression of interest to the entry into exclusivity and the inclusion of provisions in the Arrangement Agreement that Fusion believes increase the likelihood of completing the Arrangement. Each of the Transaction Committee and the Board believes, based on Fusion’s negotiations with AstraZeneca and input from senior management, that the Consideration was the highest amount of consideration per Share that AstraZeneca was willing to pay and that the Arrangement Agreement contained the most favorable terms on significant points to Fusion to which AstraZeneca was willing to agree.

Potentially Interested Counterparties. Each of the Transaction Committee and the Board considered the process conducted by Fusion, with the assistance of representatives of Centerview, to identify potential buyers taking into account the expected interest of such parties in radiopharmaceuticals generally, their financial capability to consummate a transaction of this size, regulatory considerations and their ability to move quickly and efficiently in a process. In particular, each of the Transaction Committee and the Board considered the recent discussions conducted by Fusion with other industry participants and the outcome of those discussions. Each of the Transaction Committee and the Board also considered that should any potential counterparty be interested in pursuing a transaction on terms more favorable to Fusion and its Shareholders than those contemplated by the Arrangement Agreement, such counterparty would be able to pursue such an offer for Fusion despite Fusion’s entry into an Arrangement Agreement with Parent and Purchaser.

Business Reputation of AstraZeneca and Parent. Each of the Transaction Committee and the Board considered the business reputation and capabilities of AstraZeneca and its management and the substantial financial resources of AstraZeneca and, by extension, Parent and Purchaser, which the Transaction Committee and the Board believed supported the conclusion that a transaction with AstraZeneca, Parent and Purchaser was likely to be completed in a timely and orderly manner.

Support Agreements. Each of the Transaction Committee and the Board considered that the Shareholders that held, in the aggregate, approximately 31% of the outstanding Shares as of March 18, 2024, entered into

Voting and Support Agreements obligating each of them during the term of such agreement, among other things, to vote their Shares in favor of the Arrangement Agreement, the Arrangement and the other transactions contemplated by the Arrangement Agreement, and, subject to certain exceptions, not to transfer any of the Shares that are subject to the Voting and Support Agreements.

Opinion of Financial Advisor. The Board considered the oral opinion of Centerview rendered to the Board, including all members of the Transaction Committee, on March 18, 2024, which was subsequently confirmed by delivery of a written opinion dated such date, that, as of such date and based upon and subject to the various assumptions made, procedures followed, matters considered, and qualifications and limitations upon the review undertaken by Centerview in preparing its opinion, the Consideration to be paid to the holders of Shares (other than as specified in such opinion) pursuant to the Arrangement Agreement and the CVR Agreement was fair, from a financial point of view, to such holders, as more fully described below under the heading “Opinion of Centerview Partners LLC.”

The Arrangement Agreement; Ability to Consider, Receive and Respond to Unsolicited Proposals; Receive a Reverse Termination Fee in the Event the Arrangement Agreement is Terminated Under Certain Circumstances. Each of the Transaction Committee and the Board considered the provisions of the Arrangement Agreement, including (1) the ability of Fusion under certain circumstances to entertain unsolicited proposals for an acquisition that constitute or would reasonably be expected to lead to an offer that is superior to the Arrangement, (2) the ability of the Board under certain circumstances to withdraw or modify its recommendation that Shareholders vote in favor of the Arrangement Resolution and to terminate the Arrangement Agreement in order to accept a Superior Proposal and enter into a definitive agreement with respect to such Superior Proposal, (3) the $71,680,000 termination fee payable by Fusion under certain circumstances, which the Transaction Committee and the Board believed was reasonable relative to termination fees in transactions of a similar size, would not likely preclude competing bids, and would not likely be payable unless Fusion entered into a definitive agreement for a Superior Proposal, and (4) the $102,400,000 reverse termination fee payable by Parent in the event the Arrangement Agreement is terminated as a result of certain conditions related to antitrust laws not being satisfied.

Conditions to the Consummation of the Arrangement; Likelihood of Completion. Each of the Transaction Committee and the Board considered the likelihood of completing the Arrangement, particularly in light of the terms of the Arrangement Agreement, including (1) the conditions to the Arrangement being specific and limited, (2) the exceptions contained within the “Material Adverse Effect” definition, which generally defines the standard for closing risk, and (3) the likelihood of obtaining the Interim Order, the Final Order and Regulatory Approvals and (4) the Outside Date under the Arrangement Agreement, which is anticipated to allow for sufficient time to consummate the Arrangement. Each of the Transaction Committee and the Board also considered the fact that there is no financing condition to the completion of the Arrangement.

Dissent Rights. Each of the Transaction Committee and the Board considered the availability of statutory dissenters’ rights to the Shareholders who object to the Arrangement and otherwise comply with all required procedures under the CBCA.

Product Development and Commercialization Risks. The Transaction Committee’s and the Board’s assessment of Fusion’s ability to execute as a standalone company in order to create shareholder value in excess of the Consideration, given the risks and uncertainties in Fusion’s business, including:

•

Fusion has never commercialized a product and the fact that neither FPI-2265 nor any of Fusion’s other product candidates has obtained regulatory approvals;

•

the status and the prospects for Fusion’s product candidates in Fusion’s current pipeline, including the fact that Fusion is heavily dependent on the success of FPI-2265, which still requires completion of phase 2 and phase 3 clinical studies before Fusion may seek regulatory approval and begin commercialization;

•

the significant risks and challenges associated with commercializing Fusion’s existing programs, including FPI-2265, FPI-1434, FPI-2059 and FPI-2068, platform technologies and future product candidates, including product development and pre-commercial operations, the costs associated with successfully scaling commercial operations globally, the possible failure or delays of current or future preclinical studies or clinical trials and, even if successfully developed and approved, the risk that Fusion is unable to generate adequate product revenue or achieve profitability;

•

the risk of Fusion being able to successfully enter into and monetize its assets through license, collaboration or co-promotion agreements or partnerships with industry members with comparable resources, commitment to research and development and track record of successfully commercializing product candidates, and the risks associated with any such agreements or partnerships;

•

the reliance on third parties or partners to conduct clinical trials and the risks and costs of hiring additional personnel as Fusion’s pre-commercial and clinical activities increases;

•

there are few radiopharmaceutical therapeutic products (“RPTs”) that have received marketing approval and there is limited historical clinical trial experience with RPTs, resulting in additional risk and uncertainty regarding the design and conduct of clinical trials for Fusion’s RPTs;

•

the risk that adverse side effects or other safety risks associated with FPI-2265 or Fusion’s other product candidates could delay or preclude approval, result in the suspension or discontinuation of clinical trials or the abandonment of further development of such product candidates, limit the commercial profile of an approved label, or result in significant negative consequences following marketing approval, if any;

•

the risks inherent in obtaining regulatory approvals from regulatory authorities and in obtaining adequate reimbursement from regulatory authorities and other third-party payors to be able to sell FPI-2265 or any other product candidates; and

•

the outcome, timing and costs of seeking regulatory approval and marketing approvals for Fusion’s product candidates and other product development programs.

Stakeholders. In the view of the Transaction Committee and the Board, the terms of the Arrangement Agreement treat stakeholders of Fusion fairly and equitably, including the applicable covenants in the Arrangement Agreement related to the treatment of outstanding Options, Restricted Stock Units and Warrants, Fusion’s outstanding indebtedness, and employment related matters.

Independence. The Transaction Committee consists solely of independent and disinterested directors of the Board. None of members of the Transaction Committee were or are officers or employees of Fusion.

Shareholder Approval. The Arrangement Resolution must be approved by (1) an affirmative vote of not less than 66 2/3% of the votes cast on the Arrangement Resolution by Shareholders, present in person or represented by proxy at the Meeting, each being entitled to one vote per Share, and (2) an affirmative vote of a majority of the votes cast by the Shareholders present in person or represented by proxy at the Meeting, each being entitled to one vote per Share, after excluding the votes of those Persons whose votes are required to be excluded under MI 61-101.

Determination of Fairness by the Court. Completion of the Arrangement is subject to the approval of the Court, after considering the procedural and substantive fairness of the Arrangement at a hearing at which Fusion’s unaffiliated security holders and certain others are entitled to be heard.

In the course of its deliberations, each of the Transaction Committee and the Board also considered a variety of material risks and other countervailing factors related to entering into the Arrangement Agreement, including, but not limited to, the following:

•

the Cash Consideration, while providing relative certainty of value, would not allow Shareholders to participate in future earnings or growth of Fusion, other than any payments in respect of the CVR, or to benefit from any other appreciation in value of Fusion;

•

although there is an obligation for Parent and its affiliates to use certain efforts to achieve the Milestone specified in the CVR Agreement, such Milestone might not be achieved at all or prior to August 31, 2029, such that no payment would be made with respect to any CVR;

•

the effect of the public announcement of the Arrangement Agreement, including effects on Fusion’s business relationships and Fusion’s ability to attract and retain key management and personnel;

•

the Arrangement Agreement precludes Fusion from soliciting alternative acquisition proposals and requires payment by Fusion of a $71,680,000 termination fee under certain circumstances, including in the event that the Arrangement Agreement is terminated by Fusion to accept a Superior Proposal;

•

the possibility that the Arrangement might not be consummated, and the fact that if the Arrangement is not consummated, Fusion’s directors, management and other employees will have expended extensive time and effort and will have experienced significant distractions from their work during the pendency of the Arrangement, Fusion will have incurred significant transaction costs, and Fusion’s relationships with its partners, employees and other third parties may be adversely affected;

•

the risks associated with the need to obtain the Interim Order and the Final Order and to make antitrust filings and obtain antitrust consents and approvals in the United States and Canada as further described under the heading “Regulatory Approvals”;

•

the restrictions imposed by the Arrangement Agreement on the conduct of Fusion’s business prior to completion of the Arrangement which could delay or prevent Fusion from undertaking some business opportunities that may arise during that time;

•

the risk of litigation;

•

the interests that certain directors and executive officers of Fusion may have with respect to the Arrangement that may be different from, or in addition to, their interests as Shareholders generally, as described under the heading titled “Interests of Directors and Officers in the Arrangement”;

•

the treatment of the Consideration to be received by the holders of Shares in the Arrangement as taxable to the holders of such Shares for Canadian and U.S. federal income tax purposes; and

•

the other risks set forth under the heading titled “Risk Factors”.

The foregoing discussion of the information and factors considered by the Transaction Committee and the Board in reaching its conclusions and recommendations is not intended to be exhaustive but includes the material reasons and factors considered by the Transaction Committee and the Board. In view of the wide variety of reasons and factors considered, each of the Transaction Committee and the Board did not find it practicable to, and did not, quantify, rank or otherwise assign any relative or specific weights to the various specific factors considered in reaching its determination and making its recommendation. In addition, each of the Transaction Committee and the Board did not reach any specific conclusion with respect to any of the factors or reasons considered. Instead, each of the Transaction Committee and the Board conducted an overall review of the factors and reasons described above and determined that, in the aggregate, the potential benefits considered outweighed the potential risks or possible negative consequences of the Arrangement.

The foregoing discussion of the reasoning of the Board (including the Transaction Committee) and certain information presented in this section is forward-looking in nature and, therefore, the information should be read

in light of the factors discussed in the section titled “Cautionary Note Regarding Forward-Looking Statements.” For the reasons described above, and in light of other factors that the Transaction Committee and the Board believed were appropriate to consider, the Board approved the Arrangement Agreement and the transactions contemplated thereby, including the Arrangement, and recommends that the Shareholders vote in favor of the Arrangement Resolution.

Opinion of Centerview Partners LLC

On March 18, 2024, Centerview rendered to the Board its oral opinion, subsequently confirmed in a written opinion dated such date, that, as of such date and based upon and subject to various assumptions made, procedures followed, matters considered, and qualifications and limitations upon the review undertaken by Centerview in preparing its opinion, the Consideration to be paid to the holders of Shares (other than Excluded Shares) pursuant to the Arrangement Agreement and the CVR Agreement was fair, from a financial point of view, to such holders.

The full text of Centerview’s written opinion, dated March 18, 2024, which describes the assumptions made, procedures followed, matters considered, and qualifications and limitations upon the review undertaken by Centerview in preparing its opinion, is attached as Appendix E and is incorporated herein by reference. The summary of the written opinion of Centerview set forth below is qualified in its entirety by the full text of Centerview’s written opinion attached as Appendix E. Centerview’s financial advisory services and opinion were provided for the information and assistance of the Board (in their capacity as directors and not in any other capacity) in connection with and for purposes of its consideration of the Transaction and Centerview’s opinion only addressed the fairness, from a financial point of view, as of the date thereof, to the holders of Shares (other than Excluded Shares) of the Consideration to be paid to such holders pursuant to the Arrangement Agreement and the CVR Agreement. Centerview’s opinion did not address any other term or aspect of the Arrangement Agreement, the CVR Agreement or the Transaction and does not constitute a recommendation to any Shareholder or any other person as to how such Shareholder or other person should vote with respect to the Transaction or otherwise act with respect to the Transaction or any other matter.

In connection with rendering the opinion described above and performing its related financial analyses, Centerview reviewed, among other things:

•

a draft of the Arrangement Agreement and a draft of the form of the CVR Agreement attached to the Arrangement Agreement, each such draft dated as of March 18, 2024 (collectively referred to in this summary of Centerview’s opinion as the “Draft Agreements”);

•

Annual Reports on Form 10-K of Fusion for the years ended December 31, 2022, December 31, 2021, and December 31, 2020;

•

certain interim reports to Shareholders and Quarterly Reports on Form 10-Q of Fusion;

•

certain publicly available research analyst reports for Fusion;

•

certain other communications from Fusion to its Shareholders; and

•

certain internal information relating to the business, operations, earnings, cash flow, assets, liabilities and prospects of Fusion, including certain financial forecasts, analyses and projections relating to Fusion, including the probability of realizing the Milestone under the CVR Agreement, prepared by management of Fusion and furnished to Centerview by Fusion for purposes of Centerview’s analysis, which are referred to in this summary of Centerview’s opinion as the “Forecasts,” and which are collectively referred to in this summary of Centerview’s opinion as the “Internal Data.”

Centerview also participated in discussions with members of senior management and representatives of Fusion regarding their assessment of the Internal Data, and conducted such financial studies and analyses and took into account such other information as Centerview deemed appropriate.

Centerview assumed, without independent verification or any responsibility therefor, the accuracy and completeness of the financial, legal, regulatory, tax, accounting and other information supplied to, discussed with, or reviewed by Centerview for purposes of its opinion and, with Fusion’s consent, Centerview relied upon such information as being complete and accurate. In that regard, Centerview assumed, at Fusion’s direction, that the Internal Data (including, without limitation, the Forecasts) were reasonably prepared on bases reflecting the best currently available estimates and judgments of Fusion management as to the matters covered thereby and Centerview relied, at Fusion’s direction, on the Internal Data for purposes of Centerview’s analysis and opinion. Centerview expressed no view or opinion as to the Internal Data or the assumptions on which it was based. In addition, at Fusion’s direction, Centerview did not make any independent evaluation or appraisal of any of the assets or liabilities (contingent, derivative, off-balance-sheet or otherwise) of Fusion, nor was Centerview furnished with any such evaluation or appraisal, and was not asked to conduct, and did not conduct, a physical inspection of the properties or assets of Fusion. Centerview assumed, at Fusion’s direction, that the final executed Arrangement Agreement and the final form of CVR Agreement would not differ in any respect material to Centerview’s analysis or opinion from the Draft Agreements reviewed by Centerview. Centerview also assumed, at Fusion’s direction, that the Transaction will be consummated on the terms set forth in the Arrangement Agreement and the CVR Agreement and in accordance with all applicable laws and other relevant documents or requirements, without delay or the waiver, modification or amendment of any term, condition or agreement, the effect of which would be material to Centerview’s analysis or Centerview’s opinion and that, in the course of obtaining the necessary governmental, regulatory and other approvals, consents, releases and waivers for the Transaction, no delay, limitation, restriction, condition or other change will be imposed, the effect of which would be material to Centerview’s analysis or Centerview’s opinion. Centerview did not evaluate and did not express any opinion as to the solvency or fair value of Fusion, or the ability of Fusion to pay its obligations when they come due, or as to the impact of the Transaction on such matters, under any state, federal or other laws relating to bankruptcy, insolvency or similar matters. Centerview is not a legal, regulatory, tax or accounting advisor, and Centerview expressed no opinion as to any legal, regulatory, tax or accounting matters.

Centerview’s opinion expressed no view as to, and did not address, Fusion’s underlying business decision to proceed with or effect the Transaction, or the relative merits of the Transaction as compared to any alternative business strategies or transactions that might be available to Fusion or in which Fusion might engage. Centerview’s opinion was limited to and addressed only the fairness, from a financial point of view, as of the date of Centerview’s written opinion, to the holders of the Shares (other than Excluded Shares) of the Consideration to be paid to such holders pursuant to the Arrangement Agreement and the CVR Agreement. For purposes of its opinion, Centerview was not asked to, and Centerview did not, express any view on, and its opinion did not address, any other term or aspect of the Arrangement Agreement, the CVR Agreement or the Transaction, including, without limitation, the structure or form of the Transaction, the form or terms of the CVR with respect to transferability, illiquidity or otherwise, or any other agreements or arrangements contemplated by the Arrangement Agreement or the CVR Agreement or entered into in connection with or otherwise contemplated by the Transaction, including, without limitation, the fairness of the Transaction or any other term or aspect of the Transaction to, or any consideration to be received in connection therewith by, or the impact of the Transaction on, the holders of any other class of securities, creditors or other constituencies of Fusion or any other party. In addition, Centerview expressed no view or opinion as to the fairness (financial or otherwise) of the amount, nature or any other aspect of any compensation to be paid or payable to any of the officers, directors or employees of Fusion or any party, or class of such persons in connection with the Transaction, whether relative to the Consideration to be paid to the holders of the Shares (other than Excluded Shares) pursuant to the Arrangement Agreement and the CVR Agreement or otherwise. Centerview’s opinion was necessarily based on financial, economic, monetary, currency, market and other conditions and circumstances as in effect on, and the information made available to Centerview as of, the date of Centerview’s written opinion, and Centerview does not have any obligation or responsibility to update, revise or reaffirm its opinion based on circumstances,

developments or events occurring after the date of Centerview’s written opinion. Centerview’s opinion does not constitute a recommendation to any Shareholder or any other person as to how such Shareholder or other person should vote with respect to the Transaction or otherwise act with respect to the Transaction or any other matter. Centerview’s financial advisory services and its written opinion were provided for the information and assistance of the Board (in their capacity as directors and not in any other capacity) in connection with and for purposes of its consideration of the Transaction. The issuance of Centerview’s opinion was approved by the Centerview Partners LLC Fairness Opinion Committee.

Summary of Centerview Financial Analysis

The following is a summary of the material financial analyses prepared and reviewed with the Board in connection with Centerview’s opinion, dated March 18, 2024. The summary set forth below does not purport to be a complete description of the financial analyses performed or factors considered by, and underlying the opinion of, Centerview, nor does the order of the financial analyses described represent the relative importance or weight given to those financial analyses by Centerview. Centerview may have deemed various assumptions more or less probable than other assumptions, so the reference ranges resulting from any particular portion of the analyses summarized below should not be taken to be Centerview’s view of the actual value of Fusion. In performing its analyses, Centerview made numerous assumptions with respect to industry performance, general business and economic conditions and other matters, many of which are beyond the control of Fusion or any other parties to the Transaction. None of Fusion, Parent, Purchaser or Centerview or any other person assumes responsibility if future results are materially different from those discussed. Any estimates contained in these analyses are not necessarily indicative of actual values or predictive of future results or values, which may be significantly more or less favorable than as set forth below. In addition, analyses relating to the value of Fusion do not purport to be appraisals or reflect the prices at which Fusion may actually be sold. Accordingly, the assumptions and estimates used in, and the results derived from, the financial analyses are inherently subject to substantial uncertainty. Except as otherwise noted, the following quantitative information, to the extent that it is based on market data, is based on market data as it existed on or before March 18, 2024 (the last trading day before the public announcement of the Transaction) and is not necessarily indicative of current market conditions.

Analysis of Consideration

Centerview conducted an analysis of the Consideration to be paid to the holders of Shares (other than Excluded Shares) pursuant to the Arrangement Agreement and the CVR Agreement. Such Consideration consists of, for each Share (other than Excluded Shares) held by such holders, (i) an amount in cash equal to $21.00 per Share plus (ii) one CVR, representing the right to receive a contingent payment in cash equal to $3.00 per Share, subject to applicable withholding, without interest, upon the achievement of the Milestone, as described more fully in the section entitled, “Contingent Value Rights Agreement”.

For analytical purposes, assuming that CVR holders receive an aggregate payment of $3.00 per CVR upon the achievement of the Milestone based on the probability of success of 71% as estimated by Fusion management in, and at the time implied by, the Internal Data and further assuming a discount rate of 15%, the midpoint of a range of discount rates from 14.0% to 16.0% based on Centerview’s analysis of Fusion’s weighted average cost of capital, Centerview calculated an illustrative net present value for one CVR of $1.27.

Solely for purposes of the financial analyses summarized below, the term “Implied Consideration Value” refers to an aggregate assumed implied per Share value of the Consideration of $22.27 per Share, equal, on a per Share basis, to (1) $21.00 of cash consideration payable at closing of the Transaction plus (2) the illustrative estimated risk-adjusted net present value of the CVR of $1.27, based on the midpoint of the range of discount rates, as set forth above. However, there is no guarantee that the conditions for the Milestone pursuant to the CVR Agreement will be satisfied within the time assumed in the Forecasts or at all.

Discounted Cash Flow Analysis

Centerview performed a discounted cash flow analysis of Fusion based on the Forecasts, which reflect certain assumptions as described under the section entitled, “Certain Prospective Financial Information”. A discounted cash flow analysis is a traditional valuation methodology used to derive a valuation of an asset or set of assets by calculating the “present value” of estimated future cash flows of the asset or set of assets. “Present value” refers to the current value of future cash flows or amounts and is obtained by discounting those future cash flows or amounts by a discount rate that takes into account macroeconomic assumptions and estimates of risk, the opportunity cost of capital, expected returns and other appropriate factors.

In performing this analysis, Centerview calculated a range of equity values for the Shares by (1) discounting to present value as of March 31, 2024 using discount rates ranging from 14.0% to 16.0% (based on Centerview’s analysis of Fusion’s weighted average cost of capital and considerations that Centerview deemed relevant based on its experience and professional judgment) and using a mid-year convention: (A) the forecasted risk-adjusted, after-tax unlevered free cash flows of Fusion over the period beginning on April 1, 2024 and ending on December 31, 2045, as set forth in the Forecasts, utilized by Centerview at the direction of Fusion management and as approved by the Board for use by Centerview as set forth in the section entitled “Background of the Arrangement”, (B) an implied terminal value of Fusion, calculated by Centerview by assuming that unlevered free cash flows would decline in perpetuity after December 31, 2045 at a rate of free cash flow decline of 30% year over year, as set forth in the Internal Data, (C) tax savings from usage of Fusion’s net operating losses of $235 million as of December 31, 2023 and Fusion’s estimated future losses, as set forth in the Forecasts and (D) the net present value of the estimated costs of a $250 million equity raise in each of 2025, 2026, 2027, 2028, 2029 and 2030, as set forth in the Internal Data, and (2) adding to the foregoing results Fusion’s estimated net cash of $226 million, as set forth in the Internal Data.

Centerview then calculated a range of implied equity values per Share by dividing the result of the foregoing calculations by the number of fully diluted outstanding Shares (determined using the treasury stock method and taking into account outstanding in the money options, in the money warrants and restricted stock units) as of March 15, 2024, as set forth in the Internal Data. The resulting range of implied equity values per Common Share was $17.05 to $22.60, rounded to the nearest $0.05. Centerview then compared this range to the Implied Consideration Value of $22.27 per Share to be paid to the holders of Shares (other than Excluded Shares) pursuant to the Arrangement Agreement and the CVR Agreement.

Other Factors

Centerview noted for the Board certain additional factors solely for reference and informational purposes only, including, among other things, the following:

•

Historical Stock Price Trading Analysis. Centerview reviewed historical closing trading prices of the Shares during the 52-week period ended March 18, 2024, which reflected low and high stock closing prices for Fusion during such period of $2.37 to $13.46 per Share.

•

Analyst Price Target Analysis. Centerview reviewed stock price targets for the Shares in publicly available Wall Street research analyst reports as of March 18, 2024, which indicated low and high stock price targets for Fusion ranging from $10.00 to $20.00 per Share.

•

Premiums Paid Analysis. Centerview performed an analysis of premiums paid in selected biopharma transactions involving companies for which premium data was available. The premiums in this analysis were calculated by comparing the per share acquisition price in each transaction to the closing price of the target company’s common stock for the date one day prior to the date on which the trading price of the target’s common stock was perceived to be affected by a potential transaction. Based on the analysis above and other considerations that Centerview deemed relevant in its professional judgment, Centerview applied a range of 55% to 105% to Fusion’s closing stock price on March 18, 2024 (the last trading day before the public announcement of the Transaction) of $10.64, which resulted in an implied price range of approximately $16.50 to $21.80 per Share, rounded to the nearest $0.05.

General

The preparation of a financial opinion is a complex analytical process involving various determinations as to the most appropriate and relevant methods of financial analysis and the application of those methods to the particular circumstances and, therefore, a financial opinion is not readily susceptible to summary description. In arriving at its opinion, Centerview did not draw, in isolation, conclusions from or with regard to any factor or analysis that it considered. Rather, Centerview made its determination as to fairness on the basis of its experience and professional judgment after considering the results of all of the analyses.

Centerview’s financial analyses and opinion were only one of many factors taken into consideration by the Board (including the Transaction Committee) in its evaluation of the Transaction. Consequently, the analyses described above should not be viewed as determinative of the views of the Board (including the Transaction Committee) or Fusion management with respect to the Consideration or as to whether the Board (including the Transaction Committee) would have been willing to determine that a different consideration was fair. The Consideration was determined through arm’s-length negotiations between Fusion and Parent and was approved by the Board (including the Transaction Committee). Centerview provided advice to Fusion during these negotiations. Centerview did not, however recommend any specific amount of consideration to Fusion or the Board (including the Transaction Committee) or that any specific amount of consideration constituted the only appropriate consideration for the Transaction.

Centerview is a securities firm engaged directly and through affiliates and related persons in a number of investment banking, financial advisory and merchant banking activities. In the two years prior to the date of its written opinion, except for Centerview’s current engagement, it had not been engaged to provide financial advisory or other services to Fusion, and did not receive any compensation from Fusion during such period. In the two years prior to the date of its written opinion, Centerview had not been engaged to provide financial advisory or other services to Parent, and did not receive any compensation from Parent during such period. Centerview may provide financial advisory and other services to or with respect to Fusion or Parent or their respective affiliates in the future, for which it may receive compensation. Certain (1) of Centerview and its affiliates’ directors, officers, members and employees, or family members of such persons, (2) of Centerview’s affiliates or related investment funds and (3) investment funds or other persons in which any of the foregoing may have financial interests or with which they may co-invest, may at any time acquire, hold, sell or trade, in debt, equity and other securities or financial instruments (including derivatives, bank loans or other obligations) of, or investments in, Fusion, Parent, or any of their respective affiliates, or any other party that may be involved in the Transaction.

The Board selected Centerview as its financial advisor in connection with the Transaction based on Centerview’s reputation and experience. Centerview is an internationally recognized investment banking firm that has substantial experience in transactions similar to the Transaction.

In connection with Centerview’s services as the financial advisor to the Board, Fusion has agreed to pay Centerview an aggregate fee of approximately $54 million, $1 million of which was payable upon the rendering of Centerview’s opinion and the remainder of which is payable contingent upon consummation of the Transaction, including achievement of the Milestone in accordance with the terms of the CVR Agreement. In addition, Fusion has agreed to reimburse certain of Centerview’s expenses arising, and to indemnify Centerview against certain liabilities that may arise, out of Centerview’s engagement.

Certain Prospective Financial Information

Fusion does not yet have any marketed products and does not, as a matter of course, publicly disclose forecasts or projections as to future performance, earnings or other financial results due to the inherent unpredictability of projections and their underlying assumptions and estimates and the inherent difficulty of accurately predicting financial performance for future periods. However, in connection with its strategic planning

process and at the direction of the Board, Fusion’s senior management prepared long-range projections reflecting the best currently available estimates and judgments of the senior management of Fusion on a risk adjusted basis for fiscal years 2024 through 2045 of Fusion on a stand-alone basis (the “Forecasts”). These Forecasts reflect a risk-adjusted outlook and were based on certain internal assumptions about the probability of technical success and regulatory approval, epidemiology, timing of commercial launch, sales ramp, market size, market share, pricing, reimbursement, duration of therapy, competition, partnering arrangements, market exclusivity, estimated costs and expenses, effective tax rate and utilization of net operating losses, ability to raise future capital, and other relevant factors all of which are difficult to predict and many of which are beyond Fusion’s control, relating to Fusion and its product candidates. The Forecasts were developed solely using the information available to Fusion management at the time the Forecasts were created and are based on estimates, assumptions and judgments made by Fusion management at the time of their preparation and speak only as of such time.

The Forecasts were provided to and considered by the Board and the Transaction Committee in connection with their respective evaluations of the Arrangement in comparison to Fusion’s other strategic alternatives. The Forecasts also were provided to Centerview, and the Board directed Centerview to use the Forecasts in its evaluation of the fairness of the Consideration to the holders of Shares (as summarized above under “Fairness Opinion of Centerview Partners LLC”). The Forecasts were the only financial projections with respect to Fusion used by Centerview in performing its financial analysis.

Cautionary Note About the Forecasts

The Forecasts, while necessarily presented with numerical specificity, are necessarily based on numerous variables and assumptions that are inherently uncertain, including as a result of Fusion not currently having any marketed products, and many of which are beyond Fusion’s control. The Forecasts reflect numerous estimates and assumptions made by Fusion, based on information available to Fusion at the time the Forecasts were developed, with respect to industry performance and competition, regulatory conditions, general business, economic, market and financial conditions, and matters specific to Fusion’s product candidates, all of which are difficult to predict and many of which are beyond Fusion’s control. As a result, there can be no assurance that the Forecasts accurately reflect future trends or accurately estimate the future market for any of Fusion’s product candidates. The Forecasts also reflect assumptions as to certain business decisions that are subject to change. Important factors that may affect actual results and result in the Forecasts not being achieved include, but are not limited to: (1) the success of clinical trials (including the funding therefor, anticipated patient enrollment, clinical outcomes, timing or associated costs); (2) regulatory approvals and related timelines; (3) the market acceptance of Fusion’s products; (4) Fusion’s development of such products and product candidates for different indications; (5) the impact of competitive products and pricing; (6) the effect of regulatory actions; (7) the availability of partnering arrangements on favorable terms or at all; (8) the effect of global economic conditions; (9) conditions in the financing markets and access to sufficient capital; (10) changes in applicable laws, rules and regulations; (11) accuracy of certain accounting assumptions; (12) changes in actual or projected cash flows; and (13) other risk factors described in Fusion’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023 and subsequent Quarterly Reports filed on Form 10-Q and Current Reports on Form 8-K, as well as the section titled “Cautionary Note Regarding Forward-Looking Statements” in this Circular. In addition, the Forecasts may be affected by Fusion’s ability to achieve strategic goals, objectives and targets over the applicable period. Further, the Forecasts cover multiple years and, by their nature, become subject to greater uncertainty with each successive year. Accordingly, there can be no assurance that the Forecasts will be realized, and actual results may vary materially from those shown.

Modeling and forecasting the future development and commercialization of drug candidates by a clinical-stage company is a highly speculative endeavor. In addition to the various limitations described above, there can be no assurance of the approval, or timing of approval, of any of Fusion’s product candidates, and it is possible that other therapeutic scenarios will be preferable. There also can be no assurance that Fusion will obtain the regulatory approvals necessary for the commercialization of its product candidates, or that Fusion’s competitors will not commercialize products that are safer, more effective, or more successfully marketed and sold than any

product that Fusion may market or commercialize. Since the Forecasts cover a long period of time, the Forecasts by their nature are unlikely to anticipate each circumstance that will have an effect on Fusion’s product candidates. The Forecasts were not prepared with a view toward complying with GAAP, the published guidelines of the SEC regarding projections or the guidelines established by the American Institute of Certified Public Accountants for preparation and presentation of prospective financial information. Neither Fusion’s independent registered public accounting firm nor any other independent accountant, has audited, reviewed, compiled or performed any procedures with respect to the Forecasts or expressed any opinion or any form of assurance related thereto.

The Forecasts were not prepared with a view toward public disclosure. The inclusion of the Forecasts in this Circular should not be regarded as an indication that Fusion or any of its affiliates, advisors, officers, directors or representatives considered or consider the Forecasts to be predictive of actual future events, and the Forecasts should not be relied upon as such or construed as financial guidance. Neither Fusion nor any of its affiliates assumes any responsibility for the accuracy of this information. Neither Fusion nor any of its affiliates, advisors, officers, directors or representatives can give any assurance that actual results will not differ from the Forecasts, and none of them undertakes any obligation to update or otherwise revise or reconcile the Forecasts to reflect circumstances existing after the date the Forecasts were generated or to reflect the occurrence of future events even in the event that any or all of the assumptions underlying the Forecasts are shown to be in error. Neither Fusion nor any of its affiliates, advisors, officers, directors or representatives has made or makes any representation or warranty to any Shareholder or other person regarding the ultimate performance of Fusion compared to the information contained in the Forecasts, the likelihood that the Forecasts will be achieved, the results of Fusion’s clinical trials, the timing and approval of commercial launch of any of Fusion’s products, the effectiveness or marketability of Fusion’s product candidates, or the overall future performance of Fusion. The Forecasts were prepared based on Fusion’s continued operation as a stand-alone company and do not take into account the Arrangement, including the potential synergies that may be achieved by the combined company as a result of the Arrangement or the effect of any business or strategic decision or action that has been or will be taken as a result of the execution of the Arrangement Agreement. The Forecasts are subjective in many respects and, thus, are subject to interpretation.

Certain of the measures included in the Forecasts, including unlevered free cash flow, are financial measures that are not calculated in accordance with GAAP. Such non-GAAP financial measures should not be viewed as a substitute for GAAP financial measures, and may be different from non-GAAP financial measures used by other companies. Furthermore, there are limitations inherent in non-GAAP financial measures, because they exclude charges and credits that are required to be included in a GAAP presentation. Accordingly, non-GAAP financial measures should be considered together with, and not as an alternative to, financial measures prepared in accordance with GAAP. The SEC rules, which otherwise would require a reconciliation of a non-GAAP financial measure to a GAAP financial measure, do not apply to non-GAAP financial measures provided to a board of directors or financial advisors in connection with a proposed business combination transaction such as the proposed Arrangement. In addition, reconciliations of non-GAAP financial measures to a GAAP financial measure were not provided to or relied upon by the Board or Centerview in connection with the Arrangement. Accordingly, Fusion has not provided a reconciliation of the financial measures included in the Forecasts to the relevant GAAP financial measures.

The summary of the information below is included solely to give Shareholders access to the information that was made available to Centerview and the Board, and is not included in this Circular in order to influence any Shareholder to make any investment decision with respect to the Arrangement.

In light of the foregoing factors and uncertainties inherent in the Forecasts, Shareholders are cautioned not to place undue, if any, reliance on the summary of the Forecasts set forth below. In addition, solely based on the Forecasts, Fusion’s unlevered free cash flow was calculated as set forth below for the fiscal years 2024 to 2045, which were approved by the Board for use by Centerview in connection with rendering of its opinion to the Board and in performing the related financial analysis as described above in the section titled “Fairness Opinion

of Centerview Partners LLC”. The unlevered free cash flows used by Centerview in connection with its opinion to the Board were calculated as EBIT minus tax expense minus capital expenditures plus depreciation and amortization minus change in net working capital, in each case, as included in the Forecasts.

FUSION DOES NOT INTEND TO UPDATE OR OTHERWISE REVISE THE FORECASTS TO REFLECT CIRCUMSTANCES EXISTING AFTER THE DATE WHEN MADE OR TO REFLECT THE OCCURRENCE OF FUTURE EVENTS, EVEN IN THE EVENT THAT ANY OR ALL OF THE ASSUMPTIONS UNDERLYING THE FORECASTS ARE NO LONGER APPROPRIATE.

Interests of Fusion’s Directors and Officers in the Arrangement

Incentive Awards. Certain directors and executive officers of Fusion hold outstanding Options and/or outstanding Restricted Stock Units. Immediately following the Effective Time and pursuant to the terms of the Arrangement Agreement and the Plan of Arrangement:

•

each Option with an exercise price per Share that is less than the Cash Consideration and outstanding immediately prior to the Effective Time, whether vested or unvested, will be assigned, transferred and surrendered by the holder thereof to Fusion and thereafter cancelled in consideration for (1) a cash payment by or on behalf of Fusion equal to the number of Shares into which such Option is then exercisable multiplied by the amount, if any, by which the Cash Consideration exceeds the exercise price per Share of such Option and (2) one CVR with respect to each Share into which such Option is then exercisable, in each case subject to applicable tax withholdings and other source deductions;

•

each Underwater Option outstanding immediately prior to the Effective Time, whether vested or unvested, will be surrendered by the holder thereof to Fusion and thereafter cancelled in consideration for one CVR with respect to each Share then subject to such Underwater Option, in each case subject to applicable tax withholdings and other source deductions; provided that, each CVR issued to a holder in respect of an Underwater Option will only entitle such holder to an amount in cash equal to the amount by which the Cash Consideration plus the Milestone Payment exceeds the exercise price per Share of such Underwater Option, if payable and as otherwise determined in accordance with the CVR Agreement;

•

each Restricted Stock Unit held by a Canadian Incentive Holder and outstanding immediately prior to the Effective Time, whether vested or unvested, will be assigned, transferred and surrendered by the

•

each Restricted Stock Unit held by a Non-Canadian Incentive Holder and outstanding immediately prior to the Effective Time, whether vested or unvested, will be surrendered by the holder thereof to Fusion and thereafter cancelled in consideration for (1) a cash payment by or on behalf of Fusion equal to the number of Shares underlying such Restricted Stock Unit multiplied by the Cash Consideration and (2) one CVR in respect of each Share underlying such Restricted Stock Unit, in each case subject to applicable tax withholdings and other source deductions.

Transaction Bonuses

Pursuant to the terms of the Arrangement Agreement, Fusion is permitted to implement a one-time transaction bonus program in an aggregate pool of up to $1.0 million for which all Fusion employees (including Fusion’s executive officers) are eligible to participate. All bonuses payable under the transaction bonus program will be allocated by Fusion’s Chief Executive Officer, in consultation with the Parent and in good faith and, with respect to any bonuses allocated to Fusion’s executive officers, as approved by the Board or the Compensation Committee of the Board. All bonuses payable under the transaction bonus program shall be payable on or as soon as practicable following the Effective Time, subject to the applicable employee’s continued employment through the Effective Time, or as otherwise mutually agreed between Fusion and Parent. As of the date of this Circular, the participants and the amounts each participant will be eligible to receive under the transaction bonus program have yet to be determined.

Existing Arrangements with Fusion’s Executive Officers

Fusion has existing employment agreements with each of its executive officers, which provide termination payments in certain circumstances as summarized below. Such termination payments are contingent on the executive officers entering into an effective separation agreement and general release of claims in a form and manner satisfactory to Fusion.

Eric Burak, Ph.D.

Fusion entered into a restated employment agreement with Dr. Burak, dated December 18, 2023, as amended by that certain Amendment to Employment Agreement, dated March 18, 2024 (collectively, the “Burak Employment Agreement”). The Burak Employment Agreement provides that if Dr. Burak is terminated without “cause” (as defined in the Burak Employment Agreement) within 12 months after the occurrence of the first event constituting a “change in control” (as defined in the Burak Employment Agreement), Dr. Burak will be entitled to (1) 12 months of continued base salary, (2) accrued but not yet paid bonus earned in the year preceding the year of termination, (3) a lump-sum payment equal to 100% of his annual bonus at target in the year of termination, and (4) employer-paid premiums for benefit plans for up to 12 months.

John Crowley

In June 2020, Fusion entered into a restated employment agreement with Mr. Crowley (the “Crowley Employment Agreement”). The Crowley Employment Agreement provides that if Mr. Crowley is terminated without “cause” or if Mr. Crowley resigns for “good reason” (each as defined in the Crowley Employment Agreement), in each case, within 12 months after the occurrence of the first event constituting a “change in control” (as defined in the Crowley Employment Agreement), Mr. Crowley will be entitled to (1) 12 months of base salary, (2) accrued but not yet paid bonus earned in the year preceding the year of termination, (3) a lump-sum payment equal to 100% of his annual bonus at target in the year of termination, and (4) employer-paid premiums for benefit plans for up to 12 months.

Christopher Leamon, Ph.D.

Retention Agreements

In connection with the execution of the Arrangement Agreement, Parent entered into retention agreements with each of Drs. Valliant and Burak (the “Retention Agreements”). The Retention Agreements set forth the terms and conditions of Drs. Valliant’s and Burak’s continued employment with Parent and its affiliates from and after the closing of the Arrangement. The effectiveness of the Retention Agreements is contingent on the closing of the Arrangement. Except to the extent modified in the Retention Agreements, Drs. Valliant’s and Burak’s current employment agreements will remain in full force and effect.

The Retention Agreements provide that, following the closing of the Arrangement, Dr. Valliant’s annual rate of base salary will remain unchanged immediately following the closing of the Arrangement, Dr. Burak’s annual rate of base salary will be increased to CAD$707,721 and the respective annual target bonus opportunities for Drs. Valliant and Burak will remain unchanged immediately following the closing of the Arrangement. Drs. Valliant and Burak will be eligible for (1) long-term incentive awards under the AstraZeneca PLC Performance Share Plan, with an initial target award expected value of 75% of annual base salary and 60% of annual base salary, respectively, and (2) one-time special long-term incentive awards under the AstraZeneca PLC Restricted Share Plan with a value of CAD$2 million and CAD$1 million, respectively. Such long-term incentive awards will be subject to the terms and conditions of the Performance Share Plan and Restricted Share Plan (as applicable) and the applicable award agreement.

The Arrangement Agreement - Employee Matters

Pursuant to the terms of the Arrangement Agreement, Fusion’s directors and executive officers may benefit from certain post-closing covenants related to employee benefit arrangements. See the section entitled “The Arrangement Agreement—Covenants—Employee Matters” for a description of such post-closing covenants related to employee benefit arrangements.

2024 Annual Bonuses

With respect to eligible employees of Fusion or its subsidiaries who are employed by Parent, Fusion or their respective affiliates after the Effective Time (each, a “Continuing Employee”), calendar year 2024 annual bonuses shall be paid in the ordinary course of business consistent with past practice in first quarter of calendar year 2025, subject to the achievement of applicable performance goals and each eligible Continuing Employee’s continued employment through the applicable payment date; provided, however, that if an eligible Continuing Employee experiences a Change in Control Termination (as defined in Fusion’s U.S. Employee Change in Control Severance Policy or Canadian Employee Change in Control Severance Policy, as applicable) following the Effective Time and before the date on which 2024 annual bonuses are paid, such Continuing Employee will be paid a 2024 annual bonus based on target achievement of performance goals and prorated based on the number of days elapsed between January 1, 2024 and the termination date; provided that if the termination date occurs on or following January 1, 2025, such amount shall not be subject to proration, as soon as practicable and in no event more than 60 days following such termination; provided, further, that in no event shall a Continuing

Employee be eligible for a pro rata target bonus if such Continuing Employee is entitled to a pro rata target bonus in respect of calendar year 2024 under the terms of such Continuing Employee’s employment agreement with Fusion or one of its subsidiaries.

Indemnification and Insurance

Pursuant to the terms of the Arrangement Agreement, Fusion’s directors and officers will be entitled to certain ongoing indemnification and coverage under directors’ and officers’ liability insurance policies. See the section entitled “The Arrangement Agreement —Covenants—Insurance and Indemnification” for a description of such ongoing indemnification and insurance coverage obligations.

Sources of Funds for the Arrangement

Purchaser is expected to pay approximately $2 billion upfront to acquire all of the outstanding Shares, assuming that no Shareholder validly exercises their Dissent Rights, and subject to the achievement of the Milestone under the CVR Agreement, approximately $400 million to the holders of CVRs in addition to the upfront payment. Purchaser and Parent have represented and warranted to Fusion under the Arrangement Agreement that, as of the Effective Date, Purchaser shall have sufficient funds available to satisfy the aggregate Consideration for the Shares and any other amounts payable to Securityholders pursuant to the Arrangement and the CVR Agreement, and to pay all related expenses and fees for which Purchaser is responsible under the terms of the Arrangement Agreement and the Plan of Arrangement.

Regulatory Approvals

HSR Approval. Under the HSR Act, parties to a transaction that meets certain statutory jurisdictional tests and is not otherwise exempted must provide notice of that transaction to the DOJ and the FTC, and observe a statutory waiting period before that transaction can close. The Arrangement is subject to these notification and waiting period requirements. On March 22, 2024, the parties submitted to the DOJ and FTC the notifications required under the HSR Act. The statutory waiting period expired at 11:59 p.m. (Eastern time) on April 22, 2024.

At any time before or after consummation of the Arrangement, notwithstanding clearance under the HSR Act, the Antitrust Division or the FTC could take such action under the antitrust laws as it deems necessary or desirable in the public interest, including seeking to enjoin the consummation of the Arrangement or seeking divestiture of substantial assets of Fusion or Purchaser or an affiliate of Purchaser. At any time before or after the consummation of the Arrangement, and notwithstanding clearance under the HSR Act, any state could take such action under the antitrust laws as it deems necessary or desirable in the public interest. Such action could include seeking to enjoin the consummation of the Arrangement or seeking divestiture of substantial assets of Fusion or Purchaser or an affiliate of Purchaser. Private parties may also seek to take legal action under the antitrust laws under certain circumstances.

Competition Act (Canada). Part IX of the Competition Act defines certain transactions that exceed the thresholds set out in Sections 109 and 110 of the Competition Act as “notifiable transactions.” Subject to certain limited exceptions, the parties to a notifiable transaction cannot complete the transaction until the applicable waiting period set out in the Competition Act has expired or been terminated or an appropriate waiver has been provided by the Commissioner.

The waiting period is 30 days after the day on which the parties to the notifiable transaction have submitted their respective complete notifications in prescribed form. Absent any agreement between the parties and the Commissioner to the contrary, the parties are entitled to complete their notifiable transaction at the end of the 30-day period, unless the Commissioner notifies the parties, pursuant to subsection 114(2) of the Competition Act, that the Commissioner requires additional information that is relevant to the Commissioner’s assessment of the notifiable transaction (a “supplementary information request”). In the event that the Commissioner issues a

supplementary information request, the notifiable transaction cannot be completed until 30 days after compliance with such supplementary information request, provided that there is no order issued by the Competition Tribunal in effect prohibiting completion at the relevant time and absent any agreement between the parties and the Commissioner to the contrary. The Commissioner’s substantive assessment of a notifiable transaction may extend beyond the statutory waiting period.

In addition or as an alternative to filing notifications containing the prescribed information, a party to a notifiable transaction may comply with Part IX of the Competition Act requesting and receiving: (1) an advance ruling certificate issued by the Commissioner pursuant to section 102 of the Competition Act; or (2) a no-action letter (together with a waiver of the notification requirement if necessary) provided by the Commissioner.

The Arrangement constitutes a notifiable transaction under the Competition Act. It is a condition to closing of the Arrangement that a Competition Act Approval be obtained and has not been rescinded or modified. Competition Act Approval means, either one of the following events shall have occurred: (1) an advance ruling certificate has been issued by the Commissioner of Competition pursuant to Section 102(1) of the Competition Act; or (2) both (A) a No Action Letter shall have been issued by the Commissioner of Competition, unless waived by Parent for the purpose of proceeding to complete the Arrangement, and (B) the applicable waiting period under Section 123 of the Competition Act has expired or been terminated or a waiver has been provided by the Commissioner of Competition under paragraph 113(c) of the Competition Act.

On March 28, 2024, the parties filed their respective pre-merger notification filings pursuant to section 114 of the Competition and Purchaser submitted a request to the Commissioner for the issuance of an advance ruling certificate, or in the alternative, a no-action letter, pursuant to section 102 of the Competition Act.

Investment Canada Act. Subject to certain limited exceptions, the direct acquisition of control of a Canadian business by a non-Canadian that exceeds the applicable financial threshold prescribed in Part IV of the Investment Canada Act is subject to a “net benefit to Canada” review by the responsible Minister under the Investment Canada Act and cannot be consummated unless the responsible Minister is satisfied that the acquisition is likely to be of net benefit to Canada. Where an acquisition of control of a Canadian business by a non-Canadian does not constitute a transaction, subject to a pre-closing “net benefit to Canada” review, the non-Canadian investor must submit a notification to acquire control of an existing Canadian business with the Minister designated under the Investment Canada Act at any time prior to, or not later than 30 days following closing.

The threshold for pre-closing “net benefit to Canada” review and approval under the Investment Canada Act in the case of an acquisition by a non-Canadian trade agreement investor that is not a state-owned enterprise of a Canadian-incorporated publicly-traded entity that does not carry on a cultural business in Canada is currently CAD$1.989 billion or more in enterprise value of the Canadian business being acquired, based on the entity’s market capitalization, plus its total liabilities excluding its operating liabilities, minus its cash and cash equivalents. Market capitalization is calculated by using the average daily closing price of the target’s quoted equity securities on the entity’s principal market over the most recent 20 days of trading ending before the first day of the month that immediately precedes the month in which the application for review or notification is filed. Total liabilities, excluding operating liabilities, cash and cash equivalents are determined based on the most recent quarterly financial statements. Any currency conversions in respect of market capitalization, liabilities, and cash and cash equivalents values are calculated in accordance with the Investment Canada Act’s regulations. The Arrangement does not meet the requisite threshold to constitute a transaction subject to a pre-closing “net benefit to Canada” review.

The Investment Canada Act also provides for a broad right of review in the case of transactions that potentially raise national security concerns. During the 45 day period following receipt of a complete application for review or notification, if the responsible Minister under the Investment Canada Act has reasonable grounds to believe that the transaction could be injurious to national security, the Minister can either send the non-Canadian

a notice that an order for review of the transaction (1) may be made (a “Notice of Potential Review”) or (2) has been made (a “Notice of Review”). If a Notice of Potential Review or Notice of Review is received within the initial 45-day period and the transaction has not yet closed, the transaction cannot be implemented until (1) a further notice is received confirming no order for review will be made, (2) a further notice is received indicating no further action will be taken in respect of the investment, or (3) a copy of an order is received authorizing the transaction. If a full review process is initiated, the entire process can last up to 200 days (or longer upon consent).

On March 25, 2024, Purchaser filed a “Notification to Acquire Control of an Existing Canadian Business” under the Investment Canada Act. By way of letter dated April 9, 2024, the Purchaser was advised, pursuant to section 13(1) of the Investment Canada Act, that a complete notice of the transaction had been received on March 25, 2024, and that the transaction is not subject to a net benefit review. As of the time of mailing of this Circular, the 45 day period following receipt of the complete notification has not yet elapsed.

It is a condition to completion of the Arrangement that the Investment Canada Act Approval shall have been obtained, which means that Parent submitted a notification under the Investment Canada Act and (1) forty-five (45) calendar days, as calculated under the Investment Canada Act, have elapsed from the date of certification of the notification and (2) (a) the Minister of Innovation, Science and Industry has not sent to Parent a notice under subsection 25.2(1) of the Investment Canada Act within the prescribed time period and the Governor in Council has not made an order under subsection 25.3(1) of the Investment Canada Act in respect of the transactions contemplated by the Arrangement Agreement within the prescribed time period; or (b) if such a notice has been sent or such an order has been made, Parent has subsequently received (A) a notice under paragraph 25.2(4)(a) of the Investment Canada Act indicating that a review of the transactions contemplated by the Arrangement Agreement on grounds of national security will not be commenced, (B) a notice under paragraph 25.3(6)(b) of the Investment Canada Act indicating that no further action will be taken in respect of the transactions contemplated by the Arrangement Agreement, or (C) a copy of an order under paragraph 25.4(1)(b) authorizing the transactions contemplated by the Arrangement Agreement.

Procedure for the Arrangement Becoming Effective

The Arrangement will be implemented by way of a court approved arrangement under Section 192 of Part 9 of the CBCA pursuant to the terms of the Arrangement Agreement. Upon completion of the Arrangement, Fusion will become an indirect, wholly-owned subsidiary of Parent. The following procedural steps must be taken for the Arrangement to become effective:

•

the Arrangement must be approved by the Required Shareholder Approval;

•

the Court must grant the Final Order approving the Arrangement; and

•

all other conditions precedent to the Arrangement, as set forth in the Arrangement Agreement, must be satisfied or waived in accordance with the terms thereof.

Shareholder Approval

At the Meeting, pursuant to the Interim Order, the Shareholders will be asked to, if deemed advisable, approve the Arrangement Resolution. Each Shareholder as of the close of business on the Record Date shall be entitled to vote on the Arrangement Resolution.

As a condition to the completion of the Arrangement and in accordance with the Interim Order and the CBCA (as modified by the Interim Order), the Arrangement Resolution must be approved at the Meeting by: (1) an affirmative vote of not less than 66²⁄₃% of the votes cast on the Arrangement Resolution by the Shareholders, present in person or represented by proxy at the Meeting, each being entitled to one vote per Share and (2) an affirmative vote of a majority of the votes cast by the Shareholders present in person or represented by proxy at the Meeting, each being entitled to one vote per Share, after excluding the votes of those Persons whose votes are required to be excluded under MI 61-101. The Arrangement Resolution must receive the Required

Shareholder Approval in order for Fusion to seek the Final Order and implement the Arrangement on the Effective Date in accordance with the terms of the Final Order and the Arrangement Agreement.

Court Approval of the Arrangement

The Arrangement requires approval by the Court under Section 192 of the CBCA. Prior to the mailing of this Circular, Fusion obtained the Interim Order providing for the calling and holding of the Meeting, the Dissent Rights and other procedural matters. A copy of the Interim Order is attached hereto as Appendix D of this Circular. A copy of the Notice of Application in respect of the hearing of Fusion’s application for the Final Order is attached hereto as Appendix H.

Subject to obtaining the Required Shareholder Approval at the Meeting and the terms of the Interim Order, the hearing of Fusion’s application for the Final Order is expected to take place on May 31, 2024 via a judicial videoconference at the Court located 330 University Avenue, Toronto, Ontario M5G 1R7, or at any other date and time and by any method as the Court may direct and the parties agree. Any Shareholders wishing to appear in person or to be represented by counsel at the hearing of the application for the Final Order may do so but must comply with certain procedural requirements described in the Notice of Application, including filing a notice of appearance with the Court and serving same upon Fusion and Purchaser via their respective counsel as soon as reasonably practicable and, in any event, no less than four Business Days before the date of the hearing of the application for the Final Order (as it may be rescheduled from time to time). The Court has broad discretion under the CBCA when making orders with respect to arrangements.

The Court, when hearing the application for the Final Order, will consider, among other things, whether the Arrangement is fair and reasonable. The Court may approve the Arrangement in any manner it may direct and determine appropriate. If any such amendments are made, depending on the nature of the amendments, the parties to the Arrangement Agreement may not be obligated to complete the transactions contemplated in the Arrangement Agreement. For more information, see the section entitled “The Arrangement Agreement—Termination”.

Voting and Support Agreements

On March 18, 2024, in connection with the execution of the Arrangement Agreement, the Supporting Shareholders entered into Voting and Support Agreements with Parent. Under the terms of the Voting and Support Agreements, the Supporting Shareholders have agreed, among other things, to vote their Shares in favour of the approval and authorization of the Arrangement Resolution at the Meeting and, subject to certain exceptions, not to transfer any of their Shares. As of March 18, 2024, the date of the Arrangement Agreement, the Supporting Shareholders beneficially owned an aggregate of approximately 31% of the outstanding Shares, collectively, entitled to vote at the Meeting. Any Shares of which a Supporting Shareholder acquires beneficial ownership after March 18, 2024, will be subject to the terms and conditions of the Voting and Support Agreement to the same extent as if they were owned by such Supporting Shareholder as of March 18, 2024. The Voting and Support Agreements will terminate upon termination of the Arrangement Agreement and certain other specified events.

Timing

Assuming that the Final Order is granted, and the other conditions precedent to closing are satisfied or waived to the extent legally permissible, the Arrangement will become effective as promptly as practicable and in any event within three Business Days following the satisfaction or waiver of all conditions to completion of the Arrangement set forth in the Arrangement Agreement.

Although Fusion’s, Parent’s and Purchaser’s objective is to have the Effective Date occur as soon as possible after the Meeting, the Effective Date could be delayed for a number of reasons, including, but not limited to, an objection before the Court at the hearing of the application for the Final Order or any delay in satisfying the other conditions to the completion of the Arrangement, including obtaining applicable regulatory approvals and clearances.

Delisting and Deregistration

It is expected that the Shares will be delisted from NASDAQ following the completion of the Arrangement. It is also expected that Fusion will make an application to terminate its status as a reporting issuer under applicable Canadian securities laws and to deregister its securities under the Exchange Act as soon as practicable following the completion of the Arrangement.

Expenses

Fusion estimates that expenses incurred by it in connection with the Arrangement, including legal, financial advisory, accounting, filing fees and costs, the cost of preparing, printing and mailing this Circular and fees in respect of the Fairness Opinion and other matters are not expected to exceed $60.0 million. Except as expressly provided in the Arrangement Agreement, the parties to the Arrangement Agreement agreed that all out-of-pocket expenses of the parties incurred in connection with the Arrangement, or the transactions contemplated by the Arrangement are to be paid by the party incurring such expenses.

THE MEETING

•

Via the internet prior to the Meeting: To vote over the internet prior to the Meeting, please go to the following website: https://www.proxypush.com/FUSN and follow the instructions at that site for submitting your proxy electronically.

Changing Your Vote

A registered Shareholder who has given a proxy may revoke it by depositing an instrument in writing executed by such registered Shareholder or by his or her attorney, authorized in writing, or if the registered Shareholder is a body corporate, under its corporate seal (if applicable) or by an officer or attorney thereof duly authorized, to Fusion’s corporate secretary, by delivery to Fusion Pharmaceuticals Inc., Attn: Corporate Secretary, 270 Longwood Road South, Hamilton, Ontario, Canada L8P 0A6 before the Meeting.

Beneficial Shareholders

If you are a Beneficial Shareholder because your shares are held in “street name”, meaning they are held for your account by an Intermediary, then your Intermediary that actually holds the Shares for you is the record holder and is required to vote the Shares it holds on your behalf according to your instructions. You will receive the proxy materials, as well as voting and revocation instructions, from your Intermediary or its agent. You may vote your Shares at the Meeting by proxy by following the instructions that your broker, bank or other nominee provides you. If you wish to vote your Shares virtually at the Meeting, you must:

•

Appoint yourself as your proxyholder:

•

If you plan to vote at the Meeting, print your name in the blank space provided for appointing a proxyholder on the voting instruction form and follow the instructions provided by your Intermediary for mailing your voting instructions. Your Intermediary may allow you to do this online or by telephone instead. Do not complete the voting section because you will vote in real time at the Meeting. You need to act promptly to allow enough time for your Intermediary to receive your instructions and to forward them so that you can register to vote at the Meeting.

•

Register your proxyholder: After you have appointed yourself as proxyholder, you must register in advance at https://www.proxydocs.com/FUSN.

•

If you do not give instructions to your broker, bank or other nominee, and your Intermediary does not have discretionary authority to vote the Beneficial Shareholder’s Shares on the matter, or elects not to vote in the absence of instructions from the Beneficial Shareholder, no votes will be cast on your behalf with respect to such item. If you have not completed the steps outlined above, you may still attend the Meeting as a guest. However, you will not be able to vote your Shares at the Meeting.

See the section entitled “General Proxy Matters” for more information on the solicitation of proxies.

However, Fusion and its subsidiaries will not be obligated to participate in any Pre-Closing Reorganization unless such Pre-Closing Reorganization:

Parent has also agreed:

•

to not and cause its affiliates not to, enter into or agree to enter into any transaction (including by merger, consolidation, acquisition of shares or assets, license or intellectual property, pharmaceutical or scientific collaboration, or otherwise) that (1) results in Parent acquiring any material interest in any person, or substantial portion of the assets of any person, in each case, related to the development or commercialization of (A) prostate-specific membrane antigen (PSMA)-targeted radiopharmaceutical therapies for the treatment of tumors expressing PSMA, (B) insulin-like growth factor 1 receptor (IGF-1R)-targeted radiopharmaceutical therapies for the treatment of solid tumors expressing IGF-1R, or (C) neurotensin receptor type 1 (NTSR1)-targeted radiopharmaceutical therapies for the treatment of solid tumors expressing NTSR1 and (2) would reasonably be expected to prevent, materially delay or otherwise materially impede the receipt of any regulatory approval or consummation of the Arrangement or the transactions contemplated by the Arrangement Agreement; and

In addition, Parent agreed to cooperate with Fusion in preparation of a notification under Section 11 of the Investment Canada Act, which Purchaser agreed to submit within five Business Days following the date of the Arrangement Agreement (together with the HSR Act Approval and Competition Act Approval, the “Regulatory Approvals”). Fusion and Parent will, among other things, cooperate in good faith and use their respective reasonable efforts to obtain all of the Regulatory Approvals in accordance with the terms of the Arrangement Agreement, and promptly inform the other party of any material communications received in respect of obtaining or concluding the Regulatory Approvals.

Solely with respect to obtaining the Regulatory Approvals, Parent, on behalf of the parties, has the right to determine, direct and control the strategy and timing for and make all decisions relating to and will take the lead in all meetings and communications with any Governmental Entity relating to any required submissions, responses to information requests and filings to any Governmental Entity or other person and obtaining any consent or approval of any Governmental Entity or other person, and, to the extent permissible, Fusion will use its reasonable best efforts to act consistently with such strategy, provided that, Parent consulting with, and giving reasonable consideration to the views of Fusion.

Except as otherwise contemplated by the Arrangement Agreement, no party will issue any press release or make any other public statement or disclosure with respect to the Arrangement Agreement or the Arrangement without the consent of the other parties (which consent will not be unreasonably withheld, conditioned or delayed), and no party will make any filing with any Governmental Entity (other than as contemplated in certain sections of the Arrangement Agreement or as required under applicable laws) with respect to the Arrangement Agreement or the Arrangement without the consent of the other parties (which consent will not be unreasonably withheld, conditioned or delayed). Any party that is required to make disclosure by law with respect to the Arrangement or the Arrangement Agreement will, to the extent legally permissible, use its commercially reasonable efforts to give the other party prior oral or written notice and a reasonable opportunity for it and its legal counsel to review or comment on the disclosure or filing (other than with respect to confidential information of the disclosing party contained in such disclosure or filing). The party making such disclosure required by applicable law will give reasonable consideration to any comments made by the other party or its legal counsel, and if such prior notice is not possible, shall give such notice immediately following the making of such disclosure or filing. Subject to the other terms of the Arrangement Agreement, Fusion will have no obligation to consult with Parent prior to making any disclosure related to an Acquisition Proposal or a Change in Recommendation.

Notice and Cure Provisions

Each party will promptly notify the other party of the occurrence, or failure to occur, of any event or state of facts that would, or would be reasonably expected to:

•

cause any of the representations or warranties of such party contained in the Arrangement Agreement to be untrue or inaccurate in any material respect (or in all respects if already qualified by reference to “material”, “Material Adverse Effect” or other concept of materiality) prior to the earlier of the Effective Time or termination of the Arrangement Agreement; or

•

result in the failure, in any material respect, to comply with or satisfy any covenant, condition or agreement to be complied with or satisfied by such party prior to or at the Effective Time under the Arrangement Agreement.

Notification provided under these covenants will not be deemed to cure any breach of or otherwise affect the representations, warranties, covenants, agreements or obligations of the parties (or remedies with respect thereto) or the conditions to the obligations of the parties under the Arrangement Agreement.

Neither Parent nor Fusion will be permitted to exercise its right to terminate the Arrangement Agreement pursuant to its terms, unless the party seeking to terminate the Arrangement Agreement has delivered a written notice to the other party specifying in reasonable detail all breaches of covenants, or incorrect or inaccurate representations and warranties or other matters which the terminating party asserts as the basis for termination. After delivering such a notice, provided the breaching party is proceeding diligently to cure such matter and such matter is capable of being cured prior to the Outside Date, the terminating party may not exercise such termination right if such matter has been cured prior to the earlier of (1) the Outside Date, and (2) the date that is 20 Business Days following receipt of such notice by the breaching party.

Insurance and Indemnification

Prior to the Effective Date, Fusion will purchase customary “tail” policies of directors’ and officers’ liability insurance providing protection for not less than six years after the Effective Date and with protection that is no less favourable to the directors and officers in the aggregate to the protection provided by the policies maintained by Fusion and its subsidiaries which are in effect immediately prior to the Effective Date and providing protection in respect of claims arising from facts or events which occurred on or prior to the Effective Date, and Parent will, or will cause Fusion and its subsidiaries to maintain such tail policies in effect without any reduction in scope or coverage for six years from the Effective Date. However, none of Parent, Purchaser or any of their respective affiliates will be required to expend for any such insurance policies in an aggregate amount in excess of 300% of the annual premiums for policies currently maintained by Fusion and its subsidiaries for directors’ and officers’ liability insurance in effect as of the date of the Arrangement Agreement.

Furthermore, the Arrangement Agreement provides that Parent will, and will cause Fusion and its subsidiaries to, from and after the Effective Date, honor all rights to indemnification or exculpation existing as of the date of the Arrangement Agreement in favour of present and former employees, officers and directors of Fusion and its subsidiaries to the extent that they are now existing and contained in their organizational documents or disclosed to Purchaser and Parent in Fusion’s confidential disclosure letter to the Arrangement Agreement. Such rights will not be amended or rescinded in a manner adverse to the applicable officer or director and will survive the completion of the Plan of Arrangement and will continue in full force and effect in accordance with their terms for a period of at least six years from the Effective Date.

NASDAQ Delisting

Subject to applicable law, Parent and Fusion will use their commercially reasonable efforts to cause the Shares to be delisted from NASDAQ and de-registered under the Exchange Act, with effect as soon as reasonably practicable following the Effective Time.

Rule 16b-3 Matters

Prior to the Effective Time, Fusion will take all actions reasonably necessary or advisable to cause any dispositions of Shares and derivative securities with respect to any such Shares resulting from the transactions contemplated by the Arrangement Agreement by each individual who is subject to the reporting requirements of Section 16(a) of the Exchange Act with respect to Fusion immediately prior to the Effective Time to be exempt under Rule 16b-3 promulgated under the Exchange Act, to the extent permitted by law.

Director Resignations

Prior to the Effective Time, unless otherwise directed by Parent, Fusion will use commercially reasonable efforts to cause each of its and its subsidiaries’ directors to execute and deliver a letter effectuating such director’s resignation, effective as of the Effective Time, as a director of Fusion or any of its subsidiaries, as applicable.

Section 338(g) Elections

Parent and Fusion will cooperate fully prior to the Effective Date, as and to the extent reasonably requested by the other party, to determine whether any elections under Section 338(g) of the Code (or any similar provision under state, local or non-U.S. law) will be made with respect to the acquisition of Fusion and its subsidiaries pursuant to the Arrangement Agreement. However, Parent (or any of its affiliates) will not make such election if Fusion reasonably determines, in consultation with its accountants, that such election would be likely to be materially adverse to Shareholders or Fusion and if such election is made by Parent or any of its affiliates, Parent will provide a draft of such election to Fusion for review and approval (not to be unreasonably conditioned, delayed or withheld) no later than ten Business Days prior to the Effective Date. If Fusion has not provided its consent to the filing of any election under Section 338(g) of the Code, no election will be made by Parent with respect to the transactions contemplated by the Arrangement Agreement. See “Certain U.S. Federal Income Tax Considerations – Section 338(g) Election”.

Qualified Electing Fund Election

Within 90 days after the end of Fusion’s taxable year that includes the Effective Date, Parent will, in consultation with its accountants, use commercially reasonable efforts to (1) determine whether Fusion is a “passive foreign investment company” as defined in Section 1297(a) of the Code (a “PFIC”) with respect to such taxable year, (2) determine the PFIC status of any subsidiaries of Fusion with respect to such taxable year, (3) make such PFIC determinations available to Shareholders electronically (including by posting such information on an investor relations tab of AstraZeneca’s website), and (4) provide a PFIC Annual Information Statement to allow existing Shareholders (or their direct or indirect beneficial owners) to make an election to treat Fusion or any of its subsidiaries as a “qualified electing fund” under Section 1295 of the Code. Parent may elect to provide such information on Fusion’s website at https://ir.fusionpharma.com/documents-charters.

Employee Matters

With respect to each Continuing Employee, for a period commencing on the Effective Time and ending 12 months after the Effective Time (or the date the applicable Continuing Employee’s employment terminates, if sooner) Parent has agreed to, or to cause its applicable affiliate to, provide each Continuing Employee:

•

the annual base salary or wage rate, as applicable, and an annual target cash incentive opportunity, that are, taken as a whole, no less favourable in the aggregate to the annual base salary or wage rate, as applicable, and annual target cash incentive opportunity provided to such Continuing Employee immediately prior to the Effective Time; and

•

retirement and health and welfare benefits at levels that are, taken as a whole, substantially comparable in the aggregate to either (1) those in effect for the Continuing Employee immediately prior to the

Effective Time or (2) those provided to similarly situated employees of Parent or its affiliates in the same jurisdiction as such Continuing Employee (excluding severance, defined benefit pension, post retirement medical, nonqualified deferred, equity or equity-based (including with respect to the Fusion ESPP), long-term incentive, retention, change in control and other special or non-recurring compensation or benefits).

In addition, Parent will assume liability for, honor and comply with, and will cause Fusion and its affiliates to assume liability for, honor and comply with, all Employee Plans applicable to Continuing Employees and in effect immediately prior to the Effective Time in accordance with their terms, including all severance, change in control and separation pay plans, agreements, policies and arrangements and employment agreements, and provide the severance payments and benefits required thereunder to any applicable Continuing Employee that experiences a qualifying termination of employment pursuant to the terms thereunder following the Effective Time; provided that Parent may amend, modify, replace or terminate any such Employee Plans in accordance with their respective terms.

In addition, Parent has agreed that Parent or its applicable affiliate will treat, and cause the applicable benefit plans to treat, the service of each Continuing Employee with Fusion, any of its subsidiaries or any affiliate of Fusion attributable to any period before the Effective Time as service rendered to Parent or any affiliate of Parent for purposes of eligibility to participate, vesting and benefit accrual under the vacation policy, severance, health or welfare plan(s) and defined contribution plans maintained by Parent or any of its affiliates, in each case, in which the applicable Continuing Employee participates and which are analogous to Employee Plans the applicable Continuing Employee participated in as of immediately prior to the Effective Time, except where credit would result in duplication of benefits under any pension plan that is not a defined contribution plan or under any retiree medical program or other retiree welfare benefit program. To the extent that any Continuing Employee participates in any health or other group welfare benefit plan of Parent or any of its affiliates following the Effective Time, Parent or its applicable affiliate will use commercially reasonable efforts to cause (1) any pre-existing conditions or limitations, eligibility waiting periods or required physical examinations under any health or similar welfare plan of Parent to be waived with respect to the Continuing Employees and their eligible dependents, to the extent waived under the corresponding plan in which the Continuing Employees participated immediately prior to the Effective Time, and (2) any amounts paid by a Continuing Employee under any of Fusion’s health plans in the plan year in which the Effective Time occurs to be credited towards deductibles under the health plans of Parent or any of its affiliates to the extent that any such amounts were recognized prior to the Effective Time under the analogous Employee Plan.

2020 Employee Share Purchase Plan

With respect to the Fusion ESPP, (1) no Offering (as defined in the Fusion ESPP) will commence or be extended following the date of the Arrangement Agreement, (2) for each Offering that would otherwise have an Exercise Date (as defined in the Fusion ESPP) that occurs following the anticipated Effective Time, (A) such Exercise Date will instead occur no later than seven Business Days prior to the anticipated Effective Time, and (B) each participant’s accumulated contributions under the Fusion ESPP will be used to purchase Shares in accordance with the Fusion ESPP as of such Exercise Date, (3) the applicable purchase price for Shares (as a percentage of the fair market value of Shares) will not be decreased below the levels set forth in the Fusion ESPP as of the date of the Arrangement Agreement, (4) no participant in the Fusion ESPP may increase his or her rate of payroll deductions used to purchase Shares under the Fusion ESPP following the date of the Arrangement Agreement, (5) only participants in the Fusion ESPP as of the date of the Arrangement Agreement may continue to participate in the Fusion ESPP after the date of the Arrangement Agreement, and (6) the Fusion ESPP will terminate in its entirety as of the Effective Time and no further rights will be granted or exercised under the Fusion ESPP thereafter.

Termination of Employee Plans

If Parent directs in writing at least 10 Business Days prior to the Effective Time, Fusion or its subsidiaries will (1) terminate any and all Employee Plans intended to be qualified under Section 401(a) of the Code, effective no later than the Business Day immediately preceding the Effective Time and (2) make all employee and employer contributions to such Employee Plans on behalf of all participants under such Employee Plans for all periods of service prior to the Effective Date, including such contributions that would have been made on behalf of such participants had the transactions contemplated by the Arrangement Agreement not occurred.

Guarantee of Parent

Parent has agreed to unconditionally and irrevocably guarantee in favour of Fusion the due and punctual payment and performance by Purchaser of each and every obligation of Purchaser under the Arrangement Agreement, including the payment of the Consideration payable to the Securityholders and the indemnification obligations, each in accordance with the terms of and subject to the conditions set forth in the Arrangement Agreement and the Plan of Arrangement. Parent has agreed to cause Purchaser to comply with all of such person’s obligations under or relating to the Arrangement Agreement and the Plan of Arrangement and the transactions contemplated therein. Finally, Parent has agreed that Fusion will not have to proceed first against Purchaser for such performance before exercising its rights under the guarantee against Parent, and Parent has agreed to be jointly and severally liable with Purchaser for all such guaranteed obligations as if it were the principal obligor of such obligations.

Debt Payoff

Fusion will deliver to Parent at least one Business Day prior to the Effective Time, an executed customary payoff letter and lien terminations with respect to the Loan and Security Agreement, dated as of April 4, 2022 (as amended by that certain Consent and First Amendment to Loan and Security Agreement, dated as of August 23, 2022, that certain Second Amendment to Loan and Security Agreement, dated as of September 21, 2022, and that certain Third Amendment to Loan and Security Agreement, dated as of March 30, 2023), by and among, inter alia, Fusion, and Fusion Pharmaceuticals US Inc., a Delaware corporation, as borrowers, and Oxford Finance LLC, a Delaware limited liability company, as collateral agent, and the lenders party thereto from time to time (the “Existing Credit Agreement”), in each case, in form and substance reasonably acceptable to Parent, subject to receipt by the lenders of the applicable payoff amount, for the release of all liens related to, and the prepayment, payoff, discharge and termination in full of all obligations outstanding under the Existing Credit Agreement (other than claims that expressly survive termination of the Existing Credit Agreement) subject to the occurrence of the Effective Time.

Restrictions on Solicitations of Other Offers

Fusion has agreed not to, and to cause its subsidiaries and its and their respective representatives not to, directly or indirectly:

•

enter into or otherwise engage or participate in or knowingly encourage any discussions or negotiations with (or provide any information or data to) any person (other than Parent) with respect to any inquiry, proposal or offer that constitutes, or could reasonably be expected to constitute or lead to, an Acquisition Proposal;

•

make a Change in Recommendation; or

•

In addition, Fusion agreed to, and to cause its subsidiaries and their respective representatives to, immediately cease and cause to be terminated any solicitation, knowing encouragement, discussion, negotiation or other activities with any person (other than Parent, Purchaser and their respective representatives) with respect to any inquiry, proposal or offer that constitutes, or could reasonably be expected to constitute or lead to, an Acquisition Proposal.

Neither Fusion nor any of its subsidiaries nor any of their respective representatives will, without the prior written consent of Parent, release any person from, or waive, amend, suspend or otherwise modify such person’s obligations respecting Fusion, or any of its subsidiaries, under any standstill, confidentiality, non-disclosure, business purpose, use or similar agreement or restriction to which Fusion or any of its subsidiaries is a party. However, Fusion will not be required to enforce, and will be permitted to waive, any provision of any such agreement that prohibits or purports to prohibit the submission or making of a confidential Acquisition Proposal to the Board if the Board determines in good faith, after consultation with its outside legal counsel, that the failure to do so would be inconsistent with its fiduciary duties under applicable law.

If Fusion or any of its subsidiaries or any of their respective representatives receives or otherwise becomes aware of any inquiry, proposal or offer that constitutes, or would reasonably be expected to constitute or lead to an Acquisition Proposal, or any request for copies of, access to, or disclosure of, confidential information relating to Fusion or any of its subsidiaries, including information, access or disclosure relating to the assets, properties, facilities, books and records of Fusion or any of its subsidiaries, Fusion will promptly notify Parent, at first orally, and then (and in any event within 24 hours or, if first received on a Saturday, within 48 hours, following receipt) in writing, provide Parent with unredacted copies of all documents, substantive correspondence and other materials received from or on behalf of such person and keep Parent fully informed on a current basis of the status of developments and (to the extent permitted under the Arrangement Agreement) negotiations.

If at any time prior to obtaining the Required Shareholder Approval at the Meeting, Fusion receives an unsolicited bona fide written Acquisition Proposal, Fusion may engage in discussions or negotiations with, or provide copies of, access to or disclosure of information relating to the assets, properties, facilities, books or records of Fusion or any of its subsidiaries to such person making an Acquisition Proposal, if and only if:

•

the Board first determines in good faith, after consultation with its financial and outside legal advisors, that such Acquisition Proposal constitutes or would reasonably be expected to constitute or lead to a Superior Proposal (disregarding any due diligence or access condition to which such Acquisition Proposal is subject);

•

such Acquisition Proposal did not arise as a result of a violation by Fusion directly or indirectly through its subsidiaries or its or their respective representatives of the covenants regarding non-solicitation contained in the Arrangement Agreement in any material respect, and Fusion has been and continues to be in compliance with its obligations under the additional covenants regarding non-solicitation contained in the Arrangement Agreement, in all material respects;

•

Fusion enters into a customary confidentiality and standstill agreement with such person having terms at least as onerous in all material respects as those set forth in the confidentiality and standstill agreement between Fusion and Parent (however, such confidentiality agreement need not prohibit the making of an Acquisition Proposal confidentially to the Board);

•

Fusion has provided Parent with (1) written notice stating Fusion’s intention to participate in such discussions or negotiations and to provide all such copies, access or disclosure relating to the Acquisition Proposal, including the identity of the party making such Acquisition Proposal, and (2) a copy of the confidentiality and standstill agreement referenced in the bullet above; and

•

Fusion provides Parent with any non-public information provided to such other person which was not previously provided to Parent substantially concurrently with such information being provided to such person.

The Arrangement Agreement provides that if at any time prior to obtaining the Required Shareholder Approval at the Meeting, Fusion receives an unsolicited bona fide written Acquisition Proposal that constitutes a Superior Proposal, the Board may authorize Fusion to make a Change in Recommendation or enter into a definitive agreement with respect to such Acquisition Proposal, if and only if:

•

such Superior Proposal did not arise as a result of a violation by Fusion directly or indirectly through its subsidiaries or their respective Representatives of the non-solicitation covenants contained in the Arrangement Agreement in any material respect, and Fusion has been and continues to be in compliance with its obligations under the non-solicitation covenants contained in the Arrangement Agreement in all material respects;

•

Fusion has provided Parent with written notice detailing the determination of the Board that such Acquisition Proposal constitutes a Superior Proposal and of the intention of the Board to enter into such definitive agreement;

•

Fusion has provided Purchaser with an unredacted copy of the proposed definitive agreement for the Superior Proposal and all schedules and exhibits thereto, together with any financing documents supplied to Fusion in connection therewith;

•

at least four Business Days have elapsed from the date that is the later of the date on which Purchaser received the notice of the Superior Proposal and the date on which Parent received all of the materials set forth above (it being understood that Fusion will promptly, and in any event within 24 hours, inform Parent of any amendment to the financial or other material terms of such Superior Proposal during such period);

•

after such period and subject to Fusion’s compliance with the matching conditions contained in the Arrangement Agreement, the Board has determined in good faith, after consultation with its outside legal counsel and financial advisors, that such Acquisition Proposal continues to constitute a Superior Proposal, and that failure of the Board to make a Change in Recommendation or to enter into a definitive agreement with respect to such Superior Proposal would be inconsistent with its fiduciary duties; and

•

prior to or concurrently with entering into a definitive agreement with respect to such Superior Proposal, Fusion validly terminates the Arrangement Agreement and pays a termination fee.

During the period of four Business Days described above, or such longer period as Fusion may approve:

•

Fusion will negotiate (and direct its representatives to negotiate) in good faith with Parent and its Representatives (to the extent Parent desires to negotiate);

•

Purchaser will have the right, but not the obligation, to propose revisions to the terms of the Arrangement Agreement and the Arrangement; and

•

the Board will review any such proposed revisions of the Arrangement Agreement and the Arrangement in good faith in order to determine, in consultation with its financial and outside legal advisors, whether such revisions, if given effect, would cause the Superior Proposal giving rise to the Matching Period to cease to be a Superior Proposal.

Each successive modification to any Acquisition Proposal that results in an increase to, or a modification of, the amount or form of consideration to be received by Shareholders or other amendment to the material terms or conditions thereof will constitute a new Acquisition Proposal for purposes of the requirements under the matching rights described above and Purchaser will be afforded a new two Business Day period from the later of the date on which Purchaser received the notice of the Superior Proposal and the date on which Purchaser received all of the materials as described above.

Upon the written request of Purchaser, the Board will promptly reaffirm its unanimous determination that (1) the Arrangement is fair to the Shareholders (other than Parent and its affiliates); (2) the Arrangement is in the best interest of Fusion and (3) it will recommend that Shareholders vote in favour of the Arrangement Resolution (together, the “Board Recommendation”) by press release (but on no more than two occasions per Acquisition Proposal) after any Acquisition Proposal which is not determined by the Board to be a Superior Proposal is

publicly announced or the Board determines that a proposed revision to the terms of the Arrangement Agreement as contemplated above would result in an Acquisition Proposal no longer being a Superior Proposal. Fusion publicly taking no position or a neutral position with respect to an Acquisition Proposal for a period of no more than ten Business Days following the formal announcement of such Acquisition Proposal, including a customary “stop-look-and-listen” or similar communication, will not be considered to be in violation of the Arrangement Agreement if the Board has reaffirmed the Board Recommendation before the end of such ten Business Day period.

If Fusion provides a notice of a Superior Proposal to Parent after a date that is less than five Business Days before the Meeting, Fusion may, and will if directed by Parent, postpone or adjourn the Meeting to a date that is not more than ten Business Days after the scheduled date of the Meeting, but in any event to a date that is not less than three Business Days prior to the Outside Date.

Representations and Warranties

The Arrangement Agreement contains customary representations and warranties made by each of Fusion, Parent and Purchaser. The assertions embodied in those representations and warranties are solely for the purposes of the Arrangement Agreement. Many of the parties’ representations and warranties are qualified by knowledge, materiality and/or a “Material Adverse Effect” standard.

The Arrangement Agreement contains customary representations and warranties of Fusion relating to, among other things: corporate existence and power; corporate authorization; execution and delivery of the Arrangement Agreement; governmental authorizations; non-contravention; capitalization; subsidiaries; shareholders’ and similar agreements; Canadian and U.S. securities laws matters; financial statements; disclosure/internal controls, auditors; no undisclosed material liabilities; absence of certain changes; non-arm’s length transactions; no “collateral benefit”; compliance with laws and authorizations; litigation; taxes; employee and labor matters; hostile workplace; employee plans; environmental matters; leased real property; personal property; material contracts; regulatory compliance; intellectual property; patents and patent applications; product liabilities; computer systems; cybersecurity; privacy and security; insurance; books and records; restrictions on conduct of business; funds available on termination; no shareholder rights plan; anti-money laundering and anti-corruption; customs and international trade laws; and financial advisors.

Many of Fusion’s representations and warranties are qualified by a “Material Adverse Effect” standard. For purposes of the Arrangement Agreement, “Material Adverse Effect” means any fact, state of facts, change, event, occurrence, effect or circumstance that, individually or in the aggregate, has had, or would reasonably be expected to (1) prevent, materially delay or materially impair the ability of Fusion to complete the Arrangement in accordance with the terms of the Arrangement Agreement or (2) have a material adverse effect on the business, assets financial condition or results of operations of Fusion and its subsidiaries, taken as a whole, except, with respect to (2) above, any such fact, state of facts, change, event, occurrence, effect, or circumstance resulting from or arising in connection with the following (alone or in combination) will not be taken into account when determining whether a Material Adverse Effect has occurred or would reasonably be expected to occur:

•

any fact, state of facts, change, event, occurrence, effect or circumstance generally affecting the industry in which Fusion and its subsidiaries operate;

•

any change in (1) global, national or regional political conditions (including the outbreak or escalation of war, acts of terrorism or cyberterrorism, or military actions, including any acts of war or sanctions imposed

in connection with the current disputes involving the Russian Federation and Ukraine as well as Israel and Palestine), (2) in general economic, business, political, regulatory or market conditions or in national or global financial or capital markets, or (3) interest rates or currency exchange rates;

•

any change in GAAP (or the implementation of GAAP by any Governmental Entity);

•

any adoption, proposal, implementation or change in law, or in any interpretation of law, by any Governmental Entity;

•

any natural or man-made disaster or act of God (including epidemics, pandemics, disease outbreak or other health crisis or public health event), or any escalation or worsening of any of the foregoing;

•

the failure by Fusion or any of its subsidiaries to meet any internal, third party or public projections, forecasts, budgets, guidance or estimates of revenues, earnings, cash flow, cash position, or other financial or operating metrics (however, the cause underlying such failure may be taken into account in determining whether a Material Adverse Effect has occurred if such underlying cause does not otherwise fall within any of the exceptions to this definition);

•

the execution, announcement or pendency of the Arrangement Agreement and the transactions contemplated thereby, the identity of Purchaser or Parent, or the consummation of the transactions contemplated thereby or the Arrangement, including, the impact of any of the foregoing on the relationships, contractual or otherwise, with employees, contractors, suppliers, vendors, partners, licensors, licensees, Governmental Entities or other third parties (however, this exception will not apply with respect to any representation or warranty expressly intended to address the consequences of the execution, announcement, pendency or consummation of, or compliance with, the Arrangement Agreement and the other transactions contemplated thereby or the closing conditions with respect to the representations and warranties of Fusion);

•

any action taken (or omitted to be taken) (1) with the express written consent of Parent, or (2) the failure to take any action that is expressly prohibited by the terms of the Arrangement Agreement to the extent Parent unreasonably fails to give its consent thereto after a written request therefor;

•

any change in the market price or trading volumes of any securities of Fusion or any suspension of trading of Fusion’s securities (it being understood that the causes underlying such change in market price or trading volumes may constitute or be taken into account in determining whether a Material Adverse Effect has occurred if such underlying cause does not otherwise fall within any of the exceptions to this definition);

•

any action brought by, or made by, or on behalf of, any current or former stakeholder of Fusion against Purchaser or Parent, Fusion, their affiliates, or any of their directors and officers arising out of the Arrangement Agreement or the transactions contemplated thereby including actions arising out of the exercise by any person of dissent rights; or

•

any regulatory, preclinical or clinical, pricing, reimbursement or manufacturing change, event, occurrence or effect relating to or affecting any Fusion product or product candidate (other than, in each case, if related to safety), any product or product candidate competitive with any of Fusion’s products or product candidates (including (1) any suspension, rejection, refusal of, or request to refile any regulatory application, filing or approval or delay in obtaining, making or maintaining any such regulatory application, filing or approval with respect to any Fusion product or product candidate or product or product candidate competitive with any Fusion product or product candidate, (2) any regulatory actions, requests, recommendations, determinations or decisions of any Governmental Entity related to any product or product candidate competitive with any Fusion product or product candidate, (3) any delay, hold or termination of any preclinical or clinical study, trial or test related to any Fusion product or product candidate, any product or product candidate competitive with any Fusion product or product candidate, (4) any results, outcomes, data, adverse events, side effects arising from any preclinical or clinical studies, trials or tests related to any product or product candidate competitive with any Fusion product or product candidate, (5) any market entry or threatened market entry by any product or product candidate competitive with any Fusion product or product candidate, (6) any long-term production or supply chain disruption affecting the manufacture of

any Fusion product or product candidate, and (7) any recommendations, statements, decisions or other pronouncements made, published or proposed by professional medical organizations, payors, Governmental Entities or representatives of any of the foregoing related to any Fusion product or product candidate or product or product candidate competitive with any Fusion product or product candidate).

With respect to the first five bullets above, if such matter has a disproportionate effect on Fusion and its subsidiaries, taken as a whole, relative to other comparable companies or entities operating in the industries in which Fusion and its subsidiaries operate, the incremental disproportionate impact may be taken into account in determining whether a Material Adverse Effect has occurred or would reasonably be expected to occur.

Fusion may also terminate the arrangement agreement, on written notice to Parent if:

•

a breach of any representation or warranty of, or failure to perform any covenant or agreement by, Parent or Purchaser under the Arrangement Agreement occurs that would cause any conditions of the relevant sections of the Arrangement Agreement not to be satisfied, and the breach or failure is incapable of being cured on or prior to the earlier of the Outside Date and the date that is twenty Business Days following receipt by Parent of a termination notice from Fusion with respect to such breach or failure subject to the applicable provisions of the Arrangement Agreement (provided that Fusion is not then in breach of the Arrangement Agreement so as to directly or indirectly cause any condition in the relevant sections of the Arrangement Agreement not to be satisfied);

•

prior to obtaining the Required Shareholder Approval, the Board authorizes Fusion to enter into a definitive written agreement (other than a confidentiality agreement permitted under the Arrangement Agreement) with respect to any Superior Proposal, subject to Fusion being in compliance in all material respects with the non-solicitation covenants in the Arrangement Agreement and, prior to or concurrent with such termination, paying the termination fee in accordance with the Arrangement Agreement; or

•

the conditions in the Arrangement Agreement have been satisfied or waived by the applicable party or parties (excluding the condition for Purchaser to deposit the Consideration with the Depositary and the conditions that, by their terms, cannot be satisfied until the Effective Date, in which case, there is no state of facts or circumstances then existing that would cause such conditions not to be satisfied) and Parent has failed to comply with its obligations under the Arrangement Agreement to provide the Depositary sufficient funds in order to satisfy the aggregate Consideration payable to Shareholders as provided for in the Plan of Arrangement;

Termination by Parent

Parent may also terminate the arrangement agreement, on written notice to Fusion if:

•

a breach of any representation or warranty of, or failure to perform any covenant or agreement by, Fusion under the Arrangement Agreement occurs that would cause any conditions of the relevant sections of the Arrangement Agreement not to be satisfied, and such breach or failure is incapable of being cured on or prior to the earlier of the Outside Date and the date that is twenty Business Days following receipt by Fusion of a termination notice from Parent with respect to such breach or failure subject to the applicable provisions of the Arrangement Agreement (provided that Parent is not then in breach of the Arrangement Agreement so as to directly or indirectly cause any conditions of the relevant sections of the Arrangement Agreement not to be satisfied);

•

prior to obtaining the Required Shareholder Approval: (1) the Board makes a Change in Recommendation (which includes Fusion publicly taking a neutral position or no position with respect to an Acquisition Proposal for a period of more than ten Business Days after public announcement of an Acquisition Proposal); (2) the Board approves or recommends any Acquisition Proposal; (3) the Board approves, recommends or authorizes Fusion to enter into a written agreement in respect of an Acquisition Proposal (other than a confidentiality agreement permitted under the Arrangement Agreement); or (4) Fusion publicly announces the intention to do any of the foregoing; or

•

since the date of the Arrangement Agreement, there has occurred a Material Adverse Effect that is continuing and incapable of being cured on or prior to the Outside Date.

Termination Fee

Fusion will be required to pay a termination fee of $71,680,000 if the Arrangement Agreement is terminated: (1) pursuant to the provisions described in the second bullet described above in the section of this Circular entitled “Termination of the Merger Agreement—Termination by Fusion,” (2) pursuant to the provisions

described in the third bullet described above in the section of this Circular entitled “Termination of the Merger Agreement—Termination by Parent” or (3) pursuant to the provisions described in the third bullet described above in the section of this Circular entitled “Termination of the Merger Agreement—Termination by Either Fusion or Parent” (but in the case of a termination by Fusion, only if the right to terminate the Arrangement Agreement pursuant to that section is then available to Parent) or by Parent pursuant to pursuant to the provisions described in the first bullet described above in the section of this Circular entitled “Termination of the Merger Agreement—Termination by Parent” and if: (A) at the time of such termination, Fusion is not entitled to terminate the Arrangement Agreement pursuant to the provisions described in the third bullet described above in the section of this Circular entitled “Termination of the Merger Agreement—Termination by Fusion”; (B) prior to the date of such termination, an Acquisition Proposal is made or publicly announced by any person and such Acquisition Proposal is not subsequently publicly and unconditionally withdrawn at least three Business Days before the Meeting; and (C) within 12 months of such termination, Fusion completes or enters into a definitive written agreement in respect of an Acquisition Proposal (whether or not such Acquisition Proposal is the same Acquisition Proposal referred to in clause (B) above) (provided that, for the purpose of clause (C) above, references to “20%” in the definition of “Acquisition Proposal” will be deemed to be “50%”).

Parent will be required to pay a termination fee of $102,400,000 if the Arrangement Agreement is terminated (1) pursuant to the provisions described in the second bullet described above in the section of this Circular entitled “Termination of the Merger Agreement—Termination by Either Fusion or Parent” (solely if the applicable law, injunction, judgment, order or decree relates to the HSR Act Approval and Competition Act Approval) or (2) pursuant to the provisions described in the third bullet described above in the section of this Circular entitled “Termination of the Merger Agreement—Termination by Either Fusion or Parent” if all conditions of (A) both Fusion and Parent and (B) Parent and Purchaser have been satisfied other than (x) the conditions described in the third bullet described above in the section of this Circular entitled “Conditions to the Arrangement—Mutual Conditions” (provided the Investment Canada Act Approval has been obtained) or (y) the conditions described in the fourth and fifth bullet described above in the section of this Circular entitled “Conditions to the Arrangement—Mutual Conditions” (solely as it relates to the Regulatory Approvals, other than the Investment Canada Act Approval).

In the event that either party is obligated to pay the termination fee and the termination fee is paid, such party will not have any further liability to the other party relating to or arising out of the Arrangement Agreement or the failure to complete the Arrangement (subject to certain exceptions).

Fees and Expenses

Except as otherwise provided in the Arrangement Agreement, each party will pay all out-of-pocket third party transaction expenses incurred by such party in connection with the Arrangement Agreement and the Plan of Arrangement and the transactions contemplated therein, including fees, costs and expenses incurred prior to or after the Effective Time in connection with, or incidental to, the Plan of Arrangement, whether or not the Arrangement is completed.

Injunctive Relief

Fusion, Parent and Purchaser have agreed that irreparable harm would occur for which money damages would not be an adequate remedy at law in the event that any of the provisions of the Arrangement Agreement were not performed in accordance with their specific terms or were otherwise breached. Accordingly, Fusion, Parent and Purchaser are entitled (without proof of actual damages or otherwise or posting or securing any bond or other security), in addition to any other remedy to which they are entitled at law or in equity, to specific performance of the terms of the Arrangement Agreement and an injunction or injunctions and other equitable relief to prevent breaches or threatened breaches of the Arrangement Agreement and to specifically enforce compliance with the terms of the Arrangement Agreement. Fusion, on the one hand, and Parent and Purchaser, on the other hand have agreed not to raise any objections to the availability of the equitable remedy of specific

performance to prevent or restrain breaches or threatened breaches of the Arrangement Agreement by such party or parties. Any party’s pursuit of any injunction or specific performance at any time will not be deemed an election of remedies or waiver of the right to pursue any other right or remedy to such party may be entitled including the right to pursue remedies for liabilities or damages incurred or suffered by a party in case of breach of the Arrangement Agreement involving fraud or willful breach.

Amendments

The Arrangement Agreement and the Plan of Arrangement may, at any time and from time to time before or after the holding of the Meeting but not later than the Effective Time, be amended by mutual written agreement of the parties, subject to the Plan of Arrangement, the Interim Order and the Final Order, and any such amendment may:

•

change the time for performance of any obligations or acts of the parties;

•

waive any inaccuracies or modify any representation or warranty contained in the Arrangement Agreement or in any document delivered pursuant to the Arrangement Agreement;

•

waive any inaccuracies or modify any of the covenants contained in the Arrangement Agreement and waive or modify performance of any of the obligations of the parties; or

•

modify conditions contained in the Arrangement Agreement.

However, no such amendment may reduce or materially adversely affect the Consideration to be received by Shareholders without approval of the affected Shareholders given in the same manner as required for the approval of the Arrangement or as may be ordered by the Court.

Governing Law

The Arrangement Agreement is governed by and will be interpreted and construed in accordance with the laws of the Province of Ontario and the federal laws of Canada applicable therein.

CVR Agreement

Pursuant to the Arrangement Agreement, at or prior to the Effective Time, Parent, Purchaser and the Rights Agent will enter into the CVR Agreement governing the terms of the CVRs issued pursuant to the Arrangement Agreement. The Rights Agent will keep a register of the holders of CVRs.

Each CVR represents the right to receive $3.00, in cash, without interest, subject to any applicable withholding taxes, with such payment conditioned upon the achievement of the following milestone on or prior to August 31, 2029: (1) the submission of an NDA that, if approved, would grant the right to market, distribute and sell the Product for the treatment of metastatic castration resistant prostate cancer in the United States and (2) the FDA’s confirmation of acceptance of the filing of such NDA, in each case of clauses (1) and (2), in accordance with 21 C.F.R., Part 314.101 or 21 C.F.R. Section 601.2 (as applicable).

Such Milestone may be achieved by Parent, Purchaser, any of their permitted assignees, any of their respective affiliates, or any entity that has obtained rights to file an NDA for the Product (including any acquirer or successor-in-interest to Parent or Purchaser). Parent is obligated to use certain specified efforts and resources to achieve the Milestone until the earlier to occur of the date on which the milestone is achieved and August 31, 2029. However, there can be no assurance that the Milestone will be achieved or that the $3.00 Milestone Payment will be made.

voting or dividend rights, will not represent any equity or ownership interests in Parent, Purchaser or Fusion and will not be transferable except in limited circumstances. No interest will accrue or be payable in respect of any of the amounts that may be payable in respect of the CVRs. As a holder of a CVR, you will have no greater rights against Parent and Purchaser than those accorded to general, unsecured creditors with respect to the Milestone Payment amounts that may be payable.

Voting and Support Agreements

On March 18, 2024, in connection with the execution of the Arrangement Agreement, the Supporting Shareholders entered into Voting and Support Agreements with Parent. Under the terms of the Voting and Support Agreements, the Supporting Shareholders have agreed, among other things, to vote their Shares in favour of the approval and authorization of the Arrangement Resolution at the Meeting and, subject to certain exceptions, not to transfer any of their Shares. As of March 18, 2024, the date of the Arrangement Agreement, the Supporting Shareholders beneficially owned an aggregate of approximately 31% of the outstanding Shares entitled to vote at the Meeting. Any Shares of which a Supporting Shareholder acquires beneficial ownership after March 18, 2024, will be subject to the terms and conditions of the Voting and Support Agreement to the same extent as if they were owned by such Supporting Shareholder as of March 18, 2024. The Voting and Support Agreements will terminate upon termination of the Arrangement Agreement and certain other specified events.

PRINCIPAL LEGAL MATTERS

Court Approval and Completion of the Arrangement

An arrangement under the CBCA requires sanction by the Court. On April 24, 2024, Fusion obtained the Interim Order providing for the calling and holding of the Meeting and other procedural matters. A copy of the Interim Order and the Notice of Application for the Final Order are attached to this Circular as Appendix D and Appendix H, respectively.

If the Arrangement Resolution is approved by Shareholders at the Meeting in the manner required by the Interim Order, Fusion will apply to the Court to obtain the Final Order. The hearing in respect of the Final Order is scheduled to take place via a judicial videoconference at the Court located 330 University Avenue, Toronto, Ontario M5G 1R7 on May 31, 2024, at 10 a.m. (Eastern Time), or as soon after such time as counsel may be heard. Any Shareholders wishing to appear in person or to be represented by counsel at the hearing of the application for the Final Order may do so but must comply with certain procedural requirements described in the Notice of Application for the Final Order, including filing a notice of appearance with the Court and serving same upon Fusion and Purchaser via their respective counsel as soon as reasonably practicable and, in any event, no less than two Business Days before the hearing of the application for the Final Order (as it may be rescheduled from time to time).

The Court has broad discretion under the CBCA when making orders with respect to arrangements. The Court, when hearing the application for the Final Order, will consider, among other things, the fairness of the Arrangement to Shareholders. The Court may approve the Arrangement in any manner it may direct and determine appropriate.

Once the Final Order is granted on terms consistent with the Arrangement Agreement, and the other conditions contained in the Arrangement Agreement are satisfied or waived to the extent legally permissible, the Articles of Arrangement will be filed with the Director under the CBCA for issuance of the Certificate of Arrangement giving effect to the Arrangement.

Canadian Securities Law Matters

Fusion is a reporting issuer in all provinces in Canada other than Quebec, and, accordingly, is subject to applicable securities laws in all such provinces, including MI 61-101. MI 61-101 is intended to regulate certain transactions to ensure fair treatment of shareholders in transactions which raise the potential for conflicts of interest, generally requiring enhanced disclosure, approval by a majority of shareholders excluding interested or related parties, and, in certain instances, formal valuations. The protections of MI 61-101 apply to a reporting issuer proposing to carry out, among other transactions, a “business combination” (as defined in MI 61-101) which are transactions that can result in the interests of holders of equity securities being terminated without their consent.

Since the Arrangement constitutes a “business combination”, MI 61-101 requires that the Arrangement Resolution be approved by a majority of the minority of Shareholders present virtually or represented by proxy at the Meeting, each being entitled to one vote per Share. In determining minority approval for a business combination, Fusion is required to exclude the votes attached to Shares that, to the knowledge of Fusion or any interested party or their respective directors or senior officers, after reasonable inquiry, are beneficially owned or over which control or direction is exercised by an “interested party”, a “related party of an interested party” and each of their “joint actors”, all as defined in MI 61-101. This approval is in addition to the requirement that the Arrangement Resolution must be approved by at least 66²⁄₃% of the votes cast on the Arrangement Resolution by the Shareholders present virtually or represented by proxy at the Meeting, each being entitled to one vote per Share.

A transaction, such as the Arrangement, constitutes a “business combination” for purposes of MI 61-101 if, at the time the Arrangement is agreed to, a “related party” of Fusion, such as a director or senior officer or a

holder of 10% or more of the voting rights attached to the Shares, is entitled to receive, as a consequence of the transaction, a “collateral benefit” (as defined in MI 61-101).

For the purposes of MI 61-101, a “collateral benefit” means, subject to certain specified exclusions set out below, any benefit that a related party of the issuer is entitled to receive, directly or indirectly, as a consequence of the transaction, including, without limitation, an increase in salary, a lump sum payment, a payment for surrendering securities or other enhancement in benefits related to past or future services as an employee, director or consultant of the issuer or of another person, regardless of the existence of any offsetting costs to the related party or whether the benefit is provided, or agreed to, by the issuer or another party to the transaction. The definition of “collateral benefit” contains certain exclusions. In that regard, a benefit received by a related party of Fusion is not considered to be a collateral benefit if the benefit is received solely in connection with the related party’s services as an employee, director or consultant of Fusion or an affiliated entity and: (1) the benefit is not conferred for the purpose, in whole or in part, of increasing the value of the consideration paid to the related party for securities relinquished under the Arrangement; (2) the conferring of the benefit is not, by its terms, conditional on the related party supporting the Arrangement in any manner; (3) full particulars of the benefit are disclosed in this Circular; and (4) either (A) at the time the Arrangement was agreed to, the related party and its associated entities beneficially own or exercise control or direction over less than 1% of each class of equity securities of Fusion, or (B) (x) if the transaction is a “business combination”, the related party discloses to an independent committee of the Board the amount of consideration that the related party expects it will be beneficially entitled to receive, under the terms of the Arrangement, in exchange for equity securities beneficially owned by the related party, and (y) such independent committee, acting in good faith, determines that the value of the benefit, net of any offsetting costs to the related party, is less than 5% of the value referred to in (x), and (z) the independent committee’s determination is disclosed in this Circular.

Collateral Benefit

In accordance with the terms of the Arrangement Agreement and the Arrangement, each Option and each Restricted Stock Unit outstanding immediately prior to the Effective Time (whether vested or unvested), shall be surrendered to Fusion for cancellation in exchange for the consideration set forth in the Plan of Arrangement. By virtue of such acceleration of Options and Restricted Stock Units, certain directors and officers of Fusion may be considered to be receiving a “collateral benefit”. As of the Record Date, there were 15,580,710 Options issued and outstanding.

To the knowledge of Fusion, other than Dr. John F. Valliant and Dr. Eric Burak, no related party of Fusion, within the meaning of MI 61-101, together with its associated entities, beneficially owns or exercises control or direction over 1% or more of the outstanding Shares.

As the Chief Executive Officer and a director of Fusion, Dr. John F. Valliant is a related party of Fusion. As of April 3, 2024, he beneficially owns or exercises control or direction over approximately 3.76% of the Shares as calculated in accordance with MI 61-101 on a partially diluted basis. As of April 3, 2024, he is also the holder of 960,795 unvested Options, and 192,200 Restricted Stock Units. Dr. Valliant is deemed to be receiving a “collateral benefit” as the foregoing exceptions do not apply, given that: (1) he beneficially owns or exercises control or direction over more than 1% of the outstanding Shares and (2) the aggregate value of the collateral benefits that he will be entitled to receive in connection with the Arrangement is greater than 5% of the value of the consideration that he will receive under the Arrangement in respect of the Shares that he beneficially owns. As a result, the Shares beneficially owned by Dr. Valliant will be excluded in respect of the “minority approval” described below under “Minority Approval Requirements”.

As the Chief Technology Officer of Fusion, Dr. Eric Burak is a related party of Fusion. As of April 3, 2024, he beneficially owns or exercises control or direction over approximately 1.11% of the Shares as calculated in accordance with MI 61-101 on a partially diluted basis. As of April 3, 2024, he is also the holder of 440,411 unvested Options, and 63,700 Restricted Stock Units. Dr. Burak is deemed to be receiving a “collateral benefit” as the foregoing exceptions do not apply, given that: (1) he beneficially owns or exercises control or direction

over more than 1% of the outstanding Shares and (2) the aggregate value of the collateral benefits that he will be entitled to receive in connection with the Arrangement is greater than 5% of the value of the consideration that he will receive under the Arrangement in respect of the Shares that he beneficially owns. As a result, the Shares beneficially owned by Dr. Burak will be excluded in respect of the “minority approval” described below under “Minority Approval Requirements”.

Minority Approval Requirements

As a result of the foregoing analysis, the “minority approval” requirements of MI 61-101 will apply in connection with the Arrangement. This means that, in addition to obtaining approval of the Arrangement Resolution by at least 66²⁄₃% of the votes cast by the Shareholders present in person or virtually or represented by proxy and entitled to vote at the Meeting, approval by a simple majority of the votes cast by the Shareholders present in person or virtually or represented by proxy and entitled to vote at the Meeting will also be sought, excluding the votes of the “interested parties”, any “related parties of interested parties” and each of their “joint actors” whose votes may not be included in determining “minority approval” of a “business combination” under MI 61-101.

The only votes of interested parties (or related parties of interested parties and joint actors) excluded for purposes of determining “minority approval” in accordance with MI 61-101, will be those attached to the 318,147 Shares beneficially owned by Dr. John F. Valliant and the 38,490 Shares beneficially owned by Dr. Eric Burak, which together represent approximately 0.42% of the total voting rights attached to all Shares as of the Record Date.

Formal Valuation

Fusion is not required to obtain a formal valuation under MI 61-101 because no “interested party” (1) will, as a consequence of the Arrangement, directly or indirectly acquire Fusion or the business of Fusion, or combine with Fusion, through an amalgamation, arrangement or otherwise, whether alone or with joint actors, or (2) is a party to any “connected transaction” (as defined in MI 61-101) to the business combination.

Prior Valuations and Prior Offers

To the knowledge of Fusion and its directors and officers, after reasonable enquiry, there have been no “prior valuations” (as defined in MI 61-101) prepared in respect of Fusion within the 24 months prior to the date of this Circular. Fusion has not received any bona fide prior offer during the 24 months before the date of the Arrangement Agreement that relates to the subject matter or is otherwise relevant to the Arrangement.

CERTAIN CANADIAN FEDERAL INCOME TAX CONSIDERATIONS

The following summary describes the principal Canadian federal income tax considerations under the Tax Act relating to the Arrangement. This summary is generally applicable to a beneficial owner of Shares who, for the purposes of the Tax Act and at all relevant times, (1) deals at arm’s length with Fusion and Purchaser, (2) is not affiliated with Fusion or Purchaser, (3) disposes of Shares under the Arrangement, and (4) holds Shares as capital property (a “Holder”).

Generally, the Shares will be considered capital property to a Holder for purposes of the Tax Act unless the Holder acquires or holds such shares in the course of carrying on a business of buying and selling securities or in a transaction or transactions considered to be an adventure or concern in the nature of trade.

This summary does not address the tax consequences of the Arrangement to holders of Options, Warrants or Restricted Stock Units. Such holders should consult their own tax advisors.

This summary is based upon the current provisions of the Tax Act in force as at the date hereof, the regulations thereunder, and an understanding of the administrative policies and assessing practices of the Canada Revenue Agency (the “CRA”) published in writing prior to the date hereof. This summary also takes into account all specific proposals to amend the Tax Act publicly announced by or on behalf of the Minister of Finance (Canada) prior to the date hereof (the “Proposed Amendments”) and assumes that all Proposed Amendments will be enacted in the form proposed. However, no assurances can be given that the Proposed Amendments will be enacted as proposed, or at all. This summary does not otherwise take into account or anticipate any changes in law or administrative policies or assessing practices, whether by legislative, regulatory, administrative or judicial action or decision, nor does it take into account provincial, territorial or foreign tax legislation or considerations, which may be different from those discussed in this summary.

This summary is not applicable to a Holder (1) that is a “financial institution” as defined in the Tax Act for the purposes of the “mark-to-market property” rules contained in the Tax Act; (2) that is a “specified financial institution” as defined in the Tax Act; (3) who has acquired Shares on the exercise of an option, warrant, or through any equity-based employment compensation arrangement or otherwise in the course of employment; (4) an interest in which is a “tax shelter investment” (as defined in the Tax Act); (5) that is exempt from tax under Part I of the Tax Act; (6) who reports its “Canadian tax results” within the meaning of section 261 of the Tax Act in a currency other than Canadian currency; (7) that has entered into or will enter into a “derivative forward agreement” or “synthetic disposition arrangement” (as defined in the Tax Act) in respect of the Shares or the CVRs; (8) that is a “foreign affiliate” (as defined in the Tax Act) of a taxpayer resident in Canada. Such Holders should consult their own tax advisors with respect to the income tax consequences applicable to the Arrangement.

This summary is of a general nature only and is not, and is not intended to be, nor should it be construed to be, legal or tax advice to any particular Holder. This summary is not exhaustive of all Canadian federal income tax considerations. Accordingly, Holders should consult their own tax advisors with respect to the tax consequences of the Arrangement and any other consequences to them of such transactions under Canadian federal, provincial, territorial, local and foreign tax laws, having regard to their own particular circumstances.

The Canadian federal income tax consequences to a Holder of the receipt, holding and disposition of CVRs and the reporting of amounts in respect thereof for Canadian federal income tax purposes are not entirely clear. The description in this summary of the consequences under the Tax Act of the receipt, holding and disposition of CVRs is therefore not free from doubt. Shareholders are urged to consult their own tax advisors regarding such consequences.

For the purposes of the Tax Act, all amounts relating to the acquisition, holding or disposition of Shares and CVRs must be expressed in Canadian dollars. Amounts denominated in foreign currency must be converted into

Canadian dollars using the appropriate exchange rate on the date such amounts arise (as determined in accordance with the detailed rules contained in the Tax Act).

Holders Resident in Canada

The following portion of the summary is generally applicable to a Holder who, at all relevant times, is, or is deemed to be, resident in Canada for purposes of the Tax Act and any applicable income tax treaty or convention (a “Resident Holder”).

Certain Resident Holders who might not otherwise be considered to hold their Shares as capital property may, in certain circumstances, be entitled to make an irrevocable election in accordance with subsection 39(4) of the Tax Act to have such Shares and every other “Canadian security” (as defined in the Tax Act) owned by such Resident Holder deemed to be capital property in the taxation year in which the election is made and in all subsequent taxation years. Such Resident Holders should consult their own tax advisors for advice with respect to whether an election under subsection 39(4) of the Tax Act is available or advisable in their particular circumstances. The CVRs will not be Canadian securities for this purpose.

Disposition of Shares under the Arrangement

Generally, a Resident Holder (other than a Resident Dissenting Shareholder (as defined below)) who disposes of Shares under the Arrangement will realize a capital gain (or capital loss) equal to the amount by which the proceeds of disposition received by the Resident Holder under the Arrangement, net of any reasonable costs of disposition, exceeds (or is less than) the adjusted cost base of the Shares to the Resident Holder immediately before the disposition. For this purpose, the proceeds of disposition of each Share will be an amount equal to the sum of (i) the Cash Consideration and, (ii) subject to the application of the “cost recovery method” discussed below (see “Certain Canadian Federal Income Tax Considerations – Holders Resident in Canada – Receipt, Holding and Disposition of CVRs” below), the fair market value of the CVR at the time of the Closing.

Each Resident Holder is urged to consult its own advisor regarding the fair market value of the CVRs and the related tax consequences.

Receipt, Holding and Disposition of CVRs

Subject to the discussion below regarding the application of the “cost recovery method,” the cost to a Resident Holder of a CVR received pursuant to the Arrangement should be equal to the fair market value of the CVR at the time of the Arrangement.

If the “cost-recovery method,” discussed below, is not applicable, a Resident Holder who disposes of a CVR, including pursuant to the termination of the CVR when all of the payment obligations under the CVR have been satisfied, should realize a capital gain (or capital loss) to the extent that the proceeds of disposition received by such Holder, which should include, although not free from doubt, the payments received pursuant to the CVR, if any, net of any reasonable costs of disposition, exceed (or are less than) the Holder’s adjusted cost base in its CVR immediately before the disposition. Where the “cost-recovery method” is not applicable and no payment on the CVR is to be made, a Resident Holder should be considered to have disposed of its CVR for no proceeds and should realize a capital loss equal to the adjusted cost base of such CVR.

Notwithstanding the above, if the cost recovery method does not apply, there is a risk that the CRA may characterize any amounts payable under the CVR as amounts received on account of income, instead of proceeds of disposition of the CVR, and accordingly such amount would be fully included in the Resident Holder’s income in the year of receipt.

The CRA’s administrative position, outlined in Interpretation Bulletin IT-426R, regarding the use of the “cost recovery method” of reporting capital gains or capital losses on the sale of shares subject to an earnout agreement may apply to the disposition of Shares by Resident Holders. If the conditions to benefit from the cost recovery method are met and the CRA accepts its application, a Resident Holder should (1) not be required to include the fair market value of the CVR as part of its proceeds of disposition of a Share and (2) reduce its adjusted cost base in each Share by the Cash Consideration received at Closing and the payment receivable under the CVR when it becomes determinable. Once any such amount on account of the sale price exceeds the adjusted cost base of the Share sold (as reduced by any previous such amounts) and any reasonable costs of disposition, the excess is considered to be a capital gain that is realized by the Resident Holder at the time that the amount becomes determinable. A capital loss may be recognized by a Resident Holder under the cost recovery method at the time of Closing only to the extent the maximum amount payable to the Resident Holder for each Share (being the aggregate of the Cash Consideration and the maximum amount ultimately determined to be payable under the CVR) is less than the Resident Holder’s adjusted cost base of the Share sold at such time and any reasonable costs of disposition.

A capital loss may also be recognized when the amount payable under the CVR becomes determinable, to the extent such amount is less than the balance of the adjusted cost base of the Share at such time.

The use of the cost recovery method by a Resident Holder will only be accepted by the CRA if certain conditions specified in Interpretation Bulletin IT-426R are met, which include complying with certain compliance requirements. The availability of the cost recovery method to Resident Holders is not entirely free from doubt. The determination of whether the conditions are met will be the sole responsibility of the Resident Holder. Accordingly, the Resident Holders are urged to consult their own tax advisors with respect to the “cost recovery method.”

The Canadian federal income tax consequences to a Resident Holder of the receipt, holding and disposition of a CVR, including the tax consequences of the receipt of payment pursuant to the CVR, where the cost recovery method is not applicable is not entirely free from doubt. Resident Holders should consult their own tax advisors to determine the tax consequences and corresponding reporting in relation to the receipt, holding and disposition of a CVR and, in particular, whether the receipt of the CVRs and payments received under the CVRs should be reported in an alternative manner to those described above.

Resident Dissenting Shareholders

A Resident Holder who validly exercises a Dissent Right under the Arrangement and is entitled to be paid fair value for their Shares in accordance with the Arrangement (a “Resident Dissenting Shareholder”) will be deemed to have transferred such Resident Dissenting Shareholder’s Shares to Purchaser in consideration for a payment of an amount equal to the fair value of such Resident Dissenting Shareholder’s Shares.

A Resident Dissenting Shareholder who is entitled to be paid the fair value of their Shares by Purchaser will be considered to have disposed of such Shares for proceeds of disposition equal to the amount received by the Resident Dissenting Shareholder (other than any portion thereof that is interest awarded by a court). In general, a Resident Dissenting Shareholder will realize a capital gain (or capital loss) equal to the amount by which such proceeds of disposition, net of any reasonable costs of disposition, exceeds (or is less than) the adjusted cost base of such Shares to the Resident Dissenting Shareholder. See “Certain Canadian Federal Income Tax Considerations – Holders Resident in Canada – Capital Gains and Capital Losses” below.

Any interest awarded by a court to a Resident Dissenting Shareholder is required to be included in the Resident Dissenting Shareholder’s income under the Tax Act.

Capital Gains and Capital Losses

Generally, and subject to the discussion in the next paragraph, a Resident Holder is required to include in computing its income for a taxation year one-half of the amount of any capital gain (a “taxable capital gain”) realized by the Resident Holder in that year. Subject to, and in accordance with the provisions of the Tax Act, a Resident Holder is required to deduct one-half of the amount of any capital loss (an “allowable capital loss”) realized in a taxation year from taxable capital gains realized in that taxation year. Allowable capital losses in excess of taxable capital gains in a taxation year may be carried back and deducted in any of the three preceding taxation years or carried forward and deducted in any subsequent taxation year against net taxable capital gains realized by the Resident Holder in such years, to the extent and under the circumstances specified in the Tax Act.

The 2024 Canadian Federal Budget released on April 16, 2024 proposed to increase the capital gains inclusion rate (i.e. the portion of any capital gain that is a taxable capital gain) to two-thirds for any capital gain realized by corporations and trusts, and by an individual in excess of $250,000 in a taxation year (calculated net of any capital losses in the current year, capital losses of other years applied to reduce capital gains in the current year, and capital gains subject to certain exemptions) for capital gains realized on or after June 25, 2024. According to these proposals, capital losses realized prior to the change in inclusion rate are expected to fully offset an equivalent capital gain realized after the rate change. However, no draft legislation to implement these proposals has yet been publicly released by the Minister of Finance (Canada), and many aspects of how the Tax Act will be amended in connection with these proposals remain unclear. Resident Holders are advised to consult their own tax advisors regarding the possible implications of the proposed change in the capital gains inclusion rate in their particular circumstances.

The amount of any capital loss realized by a Resident Holder that is a corporation on the disposition of a Share may, to the extent and under the circumstances described in the Tax Act, be reduced by the amount of any dividends received (or deemed to have been received) by it on such Share. Similar rules may apply where a corporation is a member of a partnership or a beneficiary of a trust that owns such Share, directly or indirectly through a partnership or trust. Resident Holders to whom these rules may apply are urged to consult their own tax advisors.

Other Taxes

A Resident Holder that is throughout the relevant taxation year a “Canadian-controlled private corporation” (as defined in the Tax Act) or that at any time in the year is a “substantive CCPC” (as defined in those Proposed Amendments released November 28, 2023 in Bill C-59, An Act to implement certain provisions of the fall economic statement tabled in Parliament on November 21, 2023 and certain provisions of the budget tabled in Parliament on March 28, 2023), may be liable to pay an additional tax on its “aggregate investment income” (as defined in the Tax Act), which includes amounts in respect of taxable capital gains and interest income. Such additional tax may be refundable in certain circumstances. Resident Holders should consult their own tax advisors regarding the possible implication of the Proposed Amendments regarding “substantive CCPCs” in their particular circumstances.

Capital gains realized by an individual or a trust, other than certain trusts, may give rise to a liability for alternative minimum tax under the Tax Act. Proposed Amendments were released on August 4, 2023, and on April 16, 2024 as part of the 2024 Canadian Federal Budget which, if enacted, may affect the liability of a Resident Holder for alternative minimum tax. Resident Holders should consult their own advisors with respect to the potential application of alternative minimum tax having regard to their own particular circumstances.

Eligibility for Investment

The CVRs will not be qualified investments under the Tax Act for a trust governed by a registered retirement savings plan, a registered retirement income fund, a deferred profit sharing plan, a registered disability savings plan, a registered education savings plan, a tax-free savings account, or a first home

savings account. As a result, such trusts holding CVRs or, in certain cases, the annuitant, holder or subscriber thereof may be subject to penalty taxes as a result of the trust holding CVRs. Other negative tax consequences may also result. Resident Holders should consult their own tax advisors for advice as to any actions to be taken to avoid such adverse tax consequences.

Holders Not Resident in Canada

The following portion of this summary is applicable to a Holder who, for the purposes of the Tax Act and any applicable income tax treaty or convention, and at all relevant times, is not, and is not deemed to be, resident in Canada and does not use or hold, and is not deemed to use or hold, Shares or CVRs in connection with carrying on a business in Canada (a “Non-Resident Holder”). Special rules, which are not discussed in this summary, may apply to a Non-Resident Holder that is an insurer carrying on business in Canada and elsewhere or that is an “authorized foreign bank” (as defined in the Tax Act). Such Non-Resident Holders should consult their own tax advisors.

Disposition of Shares under the Arrangement

A Non-Resident Holder should not be subject to tax under the Tax Act on any capital gain, or be entitled to deduct any capital loss, realized on the disposition of Shares or CVRs under the Arrangement unless the Shares or CVRs constitute “taxable Canadian property” and do not constitute “treaty-protected property” (each as defined in the Tax Act) of the Non-Resident Holder for purposes of the Tax Act at the time of disposition. It is not anticipated that the CVRs will constitute taxable Canadian property to Non-Resident Holders.

Generally, provided that the Shares are listed on a designated stock exchange as defined in the Tax Act (which currently includes the NASDAQ) at the time of disposition, the Shares will not constitute “taxable Canadian property” to a Non-Resident Holder at that time unless at any particular time during the 60-month period immediately preceding the time of disposition, (1) one or any combination of (A) the Non-Resident Holder, (B) persons with whom the Non-Resident Holder did not deal at arm’s length, and (C) partnerships in which the Non-Resident Holder or a person described in (B) holds a membership interest directly or indirectly through one or more partnerships, owned 25% or more of the issued shares of any class or series of shares of the Company, and (2) more than 50% of the fair market value of the Shares was derived directly or indirectly from one or any combination of: (A) real or immovable properties situated in Canada, (B) “Canadian resource properties” (as defined in the Tax Act), (C) “timber resource properties” (as defined in the Tax Act), and (D) options in respect of, or interests in, or for civil law rights in, property in any of the foregoing whether or not the property exists. Notwithstanding the foregoing, in certain circumstances set out in the Tax Act, Shares which are not otherwise taxable Canadian property could be deemed to be taxable Canadian property to the Non-Resident Holder. Non-Resident Holders whose Shares may constitute taxable Canadian property should consult their own tax advisors for advice having regard to their particular circumstances.

Even if the Shares were to be considered to be taxable Canadian property to a Non-Resident Holder as described above, a taxable capital gain or an allowable capital loss resulting from the disposition of the Shares will not be taken into account in computing the Non-Resident Holder’s taxable income earned in Canada for purposes of the Tax Act if, at the time of the disposition, the Shares constitute “treaty-protected property” of the Non-Resident Holder for purposes of the Tax Act. Shares will generally be considered “treaty-protected property” of a Non-Resident Holder for purposes of the Tax Act at the time of their disposition if any gain realized would, because of an applicable income tax treaty between Canada and the country in which the Non-Resident Holder is resident for purposes of such treaty and in respect of which the Non-Resident Holder is entitled to receive benefits thereunder, be exempt from tax under the Tax Act. Non-Resident Holders should consult their own tax advisors with respect to the availability of relief under the terms of any applicable income tax treaty.

In the event that the Shares constitute taxable Canadian property and are not treaty-protected property to a Non-Resident Holder, then the tax consequences described above under “Certain Canadian Federal Income Tax Considerations – Holders Resident in Canada – Disposition of Shares under the Arrangement” and “Certain Canadian Federal Income Tax Considerations – Holders Resident in Canada – Capital Gains and Capital Losses”

will generally apply. However, the “cost recovery method” described above for Resident Holders would not be applicable to a Non-Resident Holder who disposes of Shares under the Arrangement. A Non-Resident Holder who disposes of taxable Canadian property that is not treaty-protected property may have to file a Canadian income tax return for the year in which the disposition occurs. Non-Resident Holders whose Shares are, or may be, taxable Canadian property should consult their own tax advisors for advice having regard to their particular circumstances, including whether their Shares constitute treaty-protected property and as to any related tax compliance requirements and procedures.

Based on the current provisions of the Tax Act and the administrative policies and assessing practices of the CRA, Purchaser intends to take the position that Canadian withholding tax under Part XIII of the Tax Act should not apply to either the receipt of a CVR or payments thereunder.

Non-Resident Dissenting Shareholders

A Non-Resident Holder who has validly exercised that Non-Resident Holder’s Dissent Rights and is entitled to be paid fair value for their Shares in accordance with the Arrangement (a “Non-Resident Dissenting Shareholder”) will be deemed to transfer such Non-Resident Dissenting Shareholder’s Shares to Purchaser in consideration for a payment of an amount equal to the fair value of such Non-Resident Dissenting Shareholder’s Shares.

In general, a Non-Resident Dissenting Shareholder will not be subject to tax under the Tax Act on any capital gain, or be entitled to deduct any capital loss, realized by such Non-Resident Dissenting Shareholder on the disposition of Shares unless the Shares are “taxable Canadian property” to the Non-Resident Dissenting Shareholder and do not constitute “treaty-protected property” of the Non-Resident Dissenting Shareholder (each as defined in the Tax Act). In general, the tax consequences as described above under “Holders Not Resident in Canada – Disposition of Shares under the Arrangement” should apply to a Non-Resident Dissenting Shareholder.

The amount of any interest awarded by a court to a Non-Resident Dissenting Shareholder will not be subject to Canadian withholding tax provided that such interest is not “participating debt interest” (as defined in the Tax Act).

CERTAIN U.S. FEDERAL INCOME TAX CONSIDERATIONS

The following is a summary of certain U.S. federal income tax considerations relating to the Arrangement that may be relevant to U.S. Shareholders, as defined below, whose Shares are exchanged for cash and CVRs in the Arrangement. This summary is for general information only and is not tax advice. This summary is based on the Code, U.S. Treasury regulations (“Regulations”) promulgated or proposed thereunder and administrative and judicial interpretations thereof, all as in effect on the date hereof, and all of which are subject to differing interpretation and to change, possibly with retroactive effect. This summary assumes that a Shareholder holds its Shares as capital assets within the meaning of Section 1221 of the Code (generally, property held for investment). This summary does not address all of the U.S. federal income tax considerations that may be relevant to specific Shareholders in light of their particular circumstances or to Shareholders subject to special treatment under U.S. federal income tax law, such as banks or other financial institutions, insurance companies, dealers in securities or other Shareholders that generally mark their securities to market for U.S. federal income tax purposes, tax-exempt entities (including private foundations), retirement plans, regulated investment companies, real estate investment trusts, subchapter S corporations, partnerships or other pass-through entities for U.S. federal income tax purposes and persons who hold Shares through such partnerships or other pass-through entities, controlled foreign corporations, passive foreign investment companies, certain former citizens or residents of the United States, Shareholders that hold Shares as part of a hedge, straddle, constructive sale, conversion or other integrated transaction, persons that own or have owned within the past five years (or are deemed to own or to have owned within the past five years) 10% or more of the outstanding Shares, Shareholders that exercise their Dissent Rights, U.S. Shareholders that have a “functional currency” other than the U.S. dollar or persons who acquired their Shares pursuant to or in connection with options or other compensation arrangements. This summary also does not address certain U.S. federal income tax considerations that may be relevant to U.S. Warrant Holders. U.S. Warrant Holders should consult their tax advisors regarding the U.S. federal income tax considerations relating to the Arrangement. This summary does not address any U.S. state or local or non-U.S. tax considerations or any U.S. federal estate, gift or alternative minimum tax considerations.

As used in this section, the term “U.S. Person” means: (1) a citizen or individual resident of the United States; (2) a corporation created or organized in or under the laws of the United States, any state thereof or the District of Columbia; (3) an estate the income of which is subject to U.S. federal income tax regardless of its source; or (4) a trust (A) with respect to which a court within the United States is able to exercise primary supervision over its administration and one or more U.S. Persons have the authority to control all of its substantial decisions or (B) that has in effect a valid election under applicable U.S. Treasury regulations to be treated as a U.S. Person.

As used in this section, the term “U.S. Shareholder” means a beneficial owner of Shares that, for U.S. federal income tax purposes, is a U.S. Person.

If an entity treated as a partnership for U.S. federal income tax purposes holds Shares, the U.S. federal income tax considerations relating to the Arrangement generally will depend upon the status and activities of such entity and the particular partner. Any such entity should consult its tax advisor regarding the U.S. federal income tax considerations applicable to it and its partners relating to the Arrangement.

No ruling has been or will be sought from the U.S. Internal Revenue Service (the “IRS”) with respect to any of the U.S. federal income tax considerations discussed below, and no assurance can be given that the IRS will not take a position contrary to the discussion below, or that a court will not sustain any challenge by the IRS in the event of litigation.

Consequences of the Transaction

Subject to the discussion below under the heading “Passive Foreign Investment Company Considerations” (including if (1) a Shareholder has made a timely and effective QEF election or (2) if Fusion

has not been a PFIC during the entire period of a Shareholder’s ownership), the receipt of cash or CVRs by a U.S. Shareholder in exchange for Shares pursuant to the Arrangement will be a taxable transaction.

The amount of gain or loss a U.S. Shareholder recognizes, and the timing and potential character of a portion of such gain or loss, depends in part on the U.S. federal income tax treatment of the CVRs, which is subject to significant uncertainty. The installment method of reporting any gain attributable to the receipt of or payments on the CVRs will not be available because common shares are traded on an established securities market. The receipt of the CVRs pursuant to the Arrangement may be treated as either a “closed transaction” or as an “open transaction” for U.S. federal income tax purposes, each as discussed in more detail below.

There is no legal authority expressly addressing whether contingent payment rights with characteristics similar to the rights under the CVRs should be treated as received as part of either a closed transaction or an open transaction, and this determination is inherently factual in nature. Accordingly, U.S. Shareholders are urged to consult their tax advisors regarding this issue. The receipt of the CVRs would generally be treated as an “open transaction” if the value of the CVRs cannot be “reasonably ascertained.” Treasury Regulations state that only in “rare and extraordinary” cases would the value of contingent payment obligations not be reasonably ascertainable and, therefore, be subject to the open transaction method. Under Treasury Regulations addressing contingent payment obligations analogous to the CVRs, if the fair market value of the CVRs is reasonably ascertainable, a U.S. Shareholder should treat the transaction as a closed transaction and include the fair market value of the CVRs as additional consideration received in the Arrangement for purposes of determining gain or loss. It is possible that the CVRs may be treated as debt instruments for U.S. federal income tax purposes. However, as such treatment is unlikely, the discussion below does not address the tax consequences of such a characterization and assumes that the CVRs are not treated as debt instruments for U.S. federal income tax purposes.

The following sections discuss the possible tax treatment if the receipt of cash and CVRs in the Arrangement is treated as a closed transaction or, alternatively, as an open transaction. As a non-U.S. entity, Parent does not intend to take a position on whether the receipt of a CVR is a closed transaction or an open transaction, and with respect to the receipt of payments with respect to a CVR.

U.S. Shareholders are urged to consult their tax advisors regarding the proper characterization, method of tax accounting and tax reporting with respect to receipt of a CVR under the closed transaction method or open transaction method, as applicable in their respective case.

Treatment as a Closed Transaction. If the receipt of a CVR is part of a closed transaction for U.S. federal income tax purposes, then a U.S. Shareholder who sells or exchanges Shares pursuant to the Arrangement will generally, subject to the PFIC rules discussed below under “PFIC Considerations,” recognize capital gain or loss for U.S. federal income tax purposes in an amount equal to the difference, if any, between (1) the amount of cash received plus the fair market value (determined as of the Effective Time) of the CVRs received and (2) the U.S. Shareholder’s adjusted tax basis in common shares sold or exchanged. No express guidance under current U.S. federal income tax law is available regarding the proper method for determining the fair market value of the CVRs. Any capital gain or loss recognized will be long-term capital gain or loss if the U.S. Shareholder’s holding period for such common shares exceeds one year. The deductibility of capital losses is subject to limitations. Gain or loss generally will be determined separately for each block of common shares (that is, common shares acquired at the same cost in a single transaction) exchanged pursuant to the Arrangement.

The character of any gain, income or loss recognized with respect to a payment on a CVR is uncertain. Such payments may be treated as payments with respect to a sale or exchange of a capital asset or as giving rise to ordinary income, including in part as imputed interest, as described more fully below. If any payment received by a U.S. Shareholder in respect of a CVR (except to the extent any portion of such payment is required to be treated as imputed interest, as described below) is treated as an amount realized on the disposition of the applicable CVR by the U.S. Shareholder, the U.S. Shareholder should recognize gain equal to the difference between such payment (less any portion of such payment required to be treated as imputed interest, as described below) and the

U.S. Shareholder’s adjusted tax basis in the applicable CVR and, if the CVR expires without the milestone being achieved, as described in the CVR Agreement, loss equal to the U.S. holder’s adjusted tax basis in the applicable CVR. A U.S. Shareholder’s adjusted basis in a CVR generally will equal the CVR’s fair market value when the CVR was received pursuant to the Arrangement. The gain or loss will generally be long-term capital gain or loss if the U.S. Shareholder has held the applicable CVR for more than one year at the time of such payment or expiry. The deductibility of capital losses is subject to limitations.

Treatment as an Open Transaction. If the receipt of a CVR pursuant to the Arrangement is treated as an open transaction for U.S. federal income tax purposes, the fair market value of the CVR will not be treated as additional consideration for common shares at the time the CVR is received, and the U.S. Shareholder will not have any tax basis in the CVR. Instead, the U.S. Shareholder will take payments under a CVR into account when made or deemed made in accordance with the U.S. Shareholder’s regular method of accounting for U.S. federal income tax purposes. Generally, a portion of such payments will be treated as imputed interest, as described in more detail below, and the balance as additional consideration recognized in exchange for common shares. Although not entirely clear, and subject to the PFIC rules discussed below under “PFIC Considerations,” the cash consideration and the portion of payment on any CVR that is not treated as imputed interest will generally be applied first against a U.S. Shareholder’s adjusted tax basis in common shares and any excess thereafter treated as capital gain. A U.S. Shareholder will recognize capital loss with respect to any common shares to the extent that the holder’s adjusted tax basis in such common shares exceeds the cash consideration plus the payment (other than imputed interest), if any, in respect of the CVR, and a U.S. Shareholder may not be able to recognize such loss until the resolution of all contingencies under the CVR. Any such capital gain or loss will be long-term capital gain or loss if the U.S. Shareholders’ holding period in common shares exceeds one year. The deductibility of capital losses is subject to limitations. Gain or loss generally will be determined separately for each block of common shares (that is, common shares acquired at the same cost in a single transaction) exchanged pursuant to the Arrangement.

Imputed Interest. If the Arrangement Agreement and CVR provide for payments to be made more than one year after the Effective Time, a portion of any such payments made more than 6 months after the Effective Time may be treated as imputed interest that is ordinary income to a U.S. Shareholder. The portion of any payment made with respect to a CVR treated as imputed interest will be determined at the time such payment is made and generally should equal the excess of (1) the amount of the payment in respect of the CVR over (2) the present value of such amount as of the Effective Time, calculated using the applicable federal rate as the discount rate. The applicable federal rate is published monthly by the IRS. The relevant applicable federal rate will be the lower of the lowest applicable federal rate in effect during the three month period ending with the month that includes the date on which the Arrangement Agreement was signed, or the lowest applicable federal rate in effect during the three month period ending with the month that includes the date of the consummation of the Arrangement. A U.S. Shareholder must include in its taxable income imputed interest using such holder’s regular method of accounting for U.S. federal income tax purposes. U.S. Shareholders are urged to consult their tax advisors regarding the application of the imputed interest rules to the receipt of payments made with respect to a CVR.

Passive Foreign Investment Company Considerations

A non-U.S. corporation is considered to be a passive foreign investment company for any taxable year if either at least 75% of its gross income is passive income or at least 50% of the value of its assets (based on an average of the quarterly values of the assets) during such year is attributable to assets that produce passive income or are held for the production of passive income. If Fusion is classified as a PFIC in any year with respect to which a U.S. Shareholder owns Shares, Fusion will continue to be treated as a PFIC with respect to such U.S. Shareholder in all succeeding years during which the U.S. Shareholder owns the Shares, regardless of whether Fusion continues to meet the tests described above, unless Fusion ceases to be a PFIC and the U.S. Shareholder has made a “qualified electing fund” election (a “QEF Election”) along with a “deemed sale” election under the PFIC rules. If such a deemed sale election is made, a U.S. Shareholder will be deemed to have sold the Shares at

their fair market value on the last day of the taxable year Fusion satisfied the PFIC tests described above, and any gain from such deemed sale would be subject to the rules applicable to U.S. Shareholders who have made a QEF Election described below. After the deemed sale election, so long as Fusion does not become a PFIC in a subsequent taxable year, the U.S. Shareholder’s Shares with respect to which such election was made will not be treated as shares in a PFIC, and the U.S. Shareholder will not be subject to the rules described below with any gain from the Arrangement.

Fusion believes that it was classified as a PFIC for the taxable years ended December 31, 2023, 2022, and 2021. Our PFIC status is based on our income, assets, and activities for the entire taxable year, and it is therefore not possible to finally determine whether Fusion will satisfy the PFIC income or asset test discussed above for the taxable year of the Arrangement until after the close of such year. Furthermore, as discussed below under the heading “Section 338(g) Election,” it is possible that Parent will make a Section 338(g) Election (as defined below), in which case, any income deemed earned by Fusion as a result of Parent making a Section 338(g) Election would be taken into account for purposes of the PFIC income test for its taxable year that ends on the Effective Date.

If Fusion is or was a PFIC for any taxable year (or portion thereof) that is included in the holding period of a U.S. Shareholder, and the U.S. Shareholder did not make either a timely QEF Election for Fusion’s first taxable year as a PFIC in which the U.S. Shareholder held (or was deemed to hold) such Shares, a QEF Election along with a deemed sale election, or a mark-to-market election, such U.S. Shareholder generally will be required to report any gain recognized in the Arrangement as ordinary income, rather than as capital gain, and to compute the tax liability on any gain recognized in respect of the Shares as if such items had been earned ratably over each day in the U.S. Shareholder’s holding period (or a portion thereof) for the Shares. The amounts allocated to the taxable year of the Arrangement and to years before Fusion became a PFIC would be taxed as ordinary income. The amount allocated to prior taxable years in which Fusion was classified as a PFIC would be subject to tax at the highest rate in effect for that taxable year for individuals or corporations, as appropriate, and an interest charge would be imposed on the tax attributable to the allocated amount. U.S. Shareholders would not be able to offset any gain recognized in the Arrangement with capital losses.

QEF Election

A U.S. Shareholder may avoid the PFIC tax consequences described above in respect to the Shares by making a timely and valid QEF Election (or a QEF Election along with a deemed sale election). A U.S. Shareholder that has made a valid QEF Election generally will be required to include in income its pro rata share of net capital gains of Fusion (as capital gain) and Fusion’s other earnings and profits (as ordinary income), on a current basis, in each case whether or not distributed, in the taxable year of the U.S. Shareholder in which or with which Fusion’s taxable year ends if Fusion is treated as a PFIC for that taxable year. As a result, except as described below, if a U.S. Shareholder has made a valid QEF Election, such U.S. Shareholder generally will recognize capital gain or loss on the disposition of its Shares pursuant to the Arrangement.

A QEF Election will apply to the tax year for which such QEF Election is timely made and to all subsequent tax years, unless such QEF Election is invalidated or terminated or the IRS consents to revocation of such QEF Election. Under the Arrangement Agreement, within 90 days after the end of Fusion’s taxable year that includes the Effective Date, Parent will, in consultation with its accountants, use commercially reasonable efforts to (1) determine whether Fusion is a PFIC with respect to such taxable year, (2) determine the PFIC status of any subsidiaries of Fusion with respect to such taxable year, (3) make such PFIC determinations available to Shareholders electronically (including by posting such information on an investor relations tab of AstraZeneca’s website), and (4) provide a PFIC Annual Information Statement to allow a U.S. Shareholder (or their direct or indirect beneficial owners) to make a QEF Election with respect to Fusion or any of its subsidiaries. Parent may elect to provide such information on Fusion’s website at https://ir.fusionpharma.com/documents-charters.

Mark-to-Market Election

A U.S. Shareholder may make a mark-to-market election with respect to its Shares only if our Shares are marketable stock. Our Shares generally will be “marketable stock” if our Shares are regularly traded on (1) a national securities exchange that is registered with the SEC, (2) the national market system established pursuant to Section 11A of the Exchange Act, or (3) a foreign securities exchange that is regulated or supervised by a governmental authority of the country in which the market is located, provided that (A) such foreign exchange has trading volume, listing, financial disclosure, and surveillance requirements, and meets other requirements and the laws of the country in which such foreign exchange is located, together with the rules of such foreign exchange, ensure that such requirements are actually enforced and (B) the rules of such foreign exchange effectively promote active trading of listed stocks. If such stock is traded on such a qualified exchange or other market, such stock generally will be “regularly traded” for any calendar year during which such stock is traded, other than in de minimis quantities, on at least 15 days during each calendar quarter. Our Shares are currently traded on NASDAQ, a national securities exchange in the United States which is registered with the SEC. We believe that our Shares were “regularly traded” in the first and second calendar quarters of 2021 and we expect that our Shares will be “regularly traded” up and until the Effective Date. U.S. Shareholders should consult their own tax advisors regarding the marketable stock rules.

A U.S. Shareholder that makes a mark-to-market election with respect to its Shares generally will not be subject to PFIC rules discussed above with respect to such Shares. However, if a U.S. Shareholder does not make a mark-to-market election beginning in the first tax year of such U.S. Shareholder’s holding period for our Shares for which we are a PFIC or such U.S. Shareholder has not made a timely QEF Election, the PFIC rules discussed above will apply to certain dispositions of, and distributions on, our Shares.

A U.S. Shareholder that makes a mark-to-market election will include in ordinary income, for each tax year in which we are a PFIC, an amount equal to the excess, if any, of (1) the fair market value of our Shares, as of the close of such tax year over (2) such U.S. Shareholder’s adjusted tax basis in such Shares. A U.S. Shareholder that makes a mark-to-market election will be allowed a deduction in an amount equal to the excess, if any, of (A) such U.S. Shareholder’s adjusted tax basis in our Shares, over (B) the fair market value of such Shares (but only to the extent of the net amount of previously included income as a result of the mark-to-market election for prior tax years).

A U.S. Shareholder that makes a mark-to-market election generally also will adjust such U.S. Shareholder’s tax basis in our Shares to reflect the amount included in gross income or allowed as a deduction because of such mark-to-market election. Upon a sale or other taxable disposition of our Shares, a U.S. Shareholder that has a valid mark-to-market election in effect will recognize ordinary income or ordinary loss (not to exceed the excess, if any, of (1) the amount included in ordinary income because of such mark-to-market election for prior tax years over (2) the amount allowed as a deduction because of such mark-to-market election for prior tax years). Losses that exceed this limitation are subject to the rules generally applicable to losses provided in the Code and Regulations.

Section 338(g) Election

The Arrangement Agreement permits Parent to make an election under Section 338(g) of the Code (a “Section 338(g) Election”) with respect to its acquisition of Shares, provided that no such election shall be made by Parent (or any of its affiliates) if Fusion reasonably determines, in consultation with its accountants, that such election would be likely to be materially adverse to Shareholders or Fusion. If Parent were to make such a Section 338(g) Election, Fusion would be treated, for U.S. federal income tax purposes, as if it had sold all of its assets to Parent. For U.S. federal income tax purposes, Fusion would recognize income gain or loss on such deemed sale of its assets and its taxable year would end as of the Effective Date.

The gross income, gain or loss, caused by a Section 338(g) election would be taken into account for purposes of the PFIC income test for the taxable year ended on the Effective Date. Depending on the amount and

nature of the gain recognized, such inclusion could result in Fusion no longer being considered a PFIC with respect to U.S. Shareholders who have made a QEF Election and deemed sale election. If Fusion satisfies the PFIC income or asset test for the taxable year ending on the Effective Date after taking into account the deemed asset sale, a U.S. Shareholder with a valid QEF Election and deemed sale election would be required to include in its income any ordinary earning and net capital gain resulting from the deemed sale of Fusion’s assets (in addition to any other ordinary earnings and net capital gain recognized by Fusion for the taxable year ending on the Effective Date). Any amounts so included under a U.S. Shareholder’s QEF Election would increase the adjusted tax basis of such U.S. Shareholder’s Shares for purposes of determining the amount of gain or loss recognized on the receipt of cash for Shares under the Arrangement.

Each U.S. Shareholder should consult its tax advisor regarding the U.S. federal income tax consequences of Purchaser making a Section 338(g) Election with respect to the Arrangement.

Medicare Tax

In addition to regular U.S. federal income tax, certain U.S. Shareholders that are individuals, estates or trusts are subject to a 3.8% tax on all or a portion of their “net investment income,” which may include payments made to a U.S. Shareholder pursuant to the Arrangement. The computation of net investment income for shareholders who dispose of shares of a PFIC or who have made a QEF election for a PFIC is complicated and each U.S. Shareholder should consult their own tax advisor regarding the U.S. federal income tax consequences to them in light of their particular circumstances.

Information Reporting Backup Withholding

Information reporting and backup withholding generally will apply to payments to a Shareholder pursuant to the Arrangement, unless such Shareholder is an entity that is exempt from information reporting and, when required, properly demonstrates its eligibility for exemption. Any payment to a U.S. Shareholder that is subject to information reporting generally will also be subject to backup withholding, unless such U.S. Shareholder provides the appropriate documentation (generally, IRS Form W-9) to the applicable withholding agent certifying that, among other things, its taxpayer identification number is correct, or otherwise establishes an exemption.

Certain stockholders (including corporations) generally are not subject to backup withholding. Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules generally will be allowed as a refund or a credit against a U.S. Shareholder’s U.S. federal income tax liability if the required information is furnished by such U.S. Shareholder on a timely basis to the IRS.

THE FOREGOING SUMMARY DOES NOT PURPORT TO BE A COMPLETE DISCUSSION OF THE POTENTIAL TAX CONSEQUENCES OF THE ARRANGEMENT. EACH SHAREHOLDER SHOULD CONSULT ITS TAX ADVISOR REGARDING THE U.S. FEDERAL, STATE AND LOCAL AND NON-U.S. INCOME, ESTATE AND OTHER TAX CONSIDERATIONS RELATING TO THE ARRANGEMENT IN LIGHT OF ITS PARTICULAR CIRCUMSTANCES. NOTHING IN THIS SUMMARY IS INTENDED TO BE, OR SHOULD BE CONSTRUED AS, TAX ADVICE.

RISK FACTORS

In evaluating whether to approve the Arrangement Resolution, Shareholders should carefully consider the following risk factors. Additional risks and uncertainties, including those currently unknown to or considered immaterial by Fusion may also adversely affect the Arrangement. The following risk factors are not a definitive list of all risk factors associated with the Arrangement. See also “Cautionary Note Regarding Forward-Looking Statements”.

Completion of the Arrangement is subject to a number of conditions that must be satisfied or waived.

The completion of the Arrangement is subject to a number of conditions precedent, some of which are outside of the control of Fusion, Parent or Purchaser, including, without limitation, approval of the Shareholders, receipt of the required Regulatory Approvals, and the granting of the Final Order. In addition, the completion of the Arrangement by Parent and Purchaser is conditional on, among other things, no material adverse effect having occurred and continuing since the date of the Arrangement Agreement. There can be no certainty, nor can Fusion, Parent or Purchaser provide any assurance, that these conditions will be satisfied or, if satisfied, when they will be satisfied. Moreover, a substantial delay in obtaining the required approvals (including the Regulatory Approvals) could result in the Arrangement not being completed. If the Arrangement is not completed for any reason, there are risks that the announcement of the Arrangement and the dedication of substantial resources of Fusion to the completion of the Arrangement could have a negative impact on Fusion’s current business relationships and could have a material adverse effect on Fusion’s current and future operations, financial condition and prospects. In addition, failure to complete the Arrangement for any reason could negatively impact the trading price of the Shares. If the Arrangement is not completed and the Board decides to seek an alternative transaction, there can be no assurance that it will be able to find a party willing to pay consideration for the Shares that is equivalent to, or more attractive than, the Consideration payable pursuant to the Arrangement.

The Arrangement Agreement may be terminated in certain circumstances, in which case an alternative transaction may not be available.

Each of Fusion and Parent has the right to terminate the Arrangement Agreement in certain circumstances. Accordingly, there is no certainty that the Arrangement Agreement will not be terminated by Fusion or Parent before the completion of the Arrangement. Failure to complete the Arrangement could materially negatively impact the trading price of the Shares. If the Arrangement Agreement is terminated and the Board decides to seek an alternative transaction, there is no guarantee that it will be able to find a party willing to pay consideration for the Shares that is equivalent to, or more attractive than, the Consideration payable pursuant to the Arrangement.

Fusion will incur costs and may have to pay a termination fee.

Certain costs relating to the Arrangement, such as certain legal, accounting and financial advisor fees, must be paid by Fusion even if the Arrangement is not completed. If the Arrangement is not completed for certain reasons, Fusion may also be required to pay a termination fee of $71,680,000 to Parent. See “The Arrangement Agreement - Termination Fee”. If Fusion is required to pay this termination fee under the Arrangement Agreement, the financial condition and ability of Fusion to fund current operations could be materially adversely affected.

The termination fee may discourage other parties from proposing a significant business transaction with Fusion.

Fusion is required to pay a termination fee in the event that the Arrangement Agreement is terminated in circumstances related to a possible alternative transaction to the Arrangement. The termination fee may discourage other parties from attempting to propose a business transaction, even if such a transaction could provide better value to Shareholders than the Arrangement.

Shareholders will no longer hold an interest in Fusion following the Arrangement.

Following the Arrangement, Shareholders will no longer hold any of the Shares and other than potential value in connection with the CVR, Shareholders will forego any future increase in value that might result from future growth and the potential achievement of Fusion’s long-term plans.

Shareholders may not receive any payments under the CVRs.

Under the Arrangement Agreement, Shareholders have the right to receive a CVR in respect of each Share owned immediately prior to the Effective Time. Shareholders have an opportunity to realize additional value if the Milestone is achieved in accordance with the terms of the CVR Agreement within the time period prescribed therein, through an additional cash payment of $3.00 per CVR. Therefore, Shareholders’ right to receive any future payment with respect to the CVRs will be contingent upon whether the Milestone is achieved following the Effective Time by August 31, 2029. If the Milestone is not achieved by August 31, 2029, no payment will be made under the CVRs and the CVRs will expire valueless. Accordingly, the value, if any, of the CVRs is speculative, and the CVRs may ultimately have no value at all.

CVRs may not be assigned or transferred except in very limited circumstances, limiting the ability for Holders to monetize the CVRs.

The CVRs will not be listed on any securities exchange and may not be sold, assigned, transferred, pledged, encumbered or in any other manner transferred or disposed of, in whole or in part other than (1) upon the death of a Holder, by will or intestacy; (2) by instrument to an inter vivos or testamentary trust, (3) pursuant to a court order; (4) by operation of law (including by consolidation or merger) or without consideration in connection with the dissolution, liquidation or termination of any corporation, limited liability corporation, partnership or other entity; (5) in the case of CVRs held through book-entry or other similar nominee form, from a nominee to the beneficial owner and, if applicable, through an Intermediary, to the extent allowable by DTC; or (6) pursuant to a Holder’s right to abandon a CVR or the deemed acquisition of CVRs by Purchaser. This means that a Holder may not have any ability to recognize the value of any payment to be made in accordance with the CVR Agreement prior to the receipt of such a payment, if any.

The Canadian federal income tax treatment of the CVRs is unclear.

The Canadian federal income tax consequences to a Shareholder in respect of the receipt, holding and disposition of the CVRs and the receipt of payments under the CVRs are not entirely clear. Shareholders are urged to consult their own tax advisors regarding the Canadian federal income tax consequences to them of the receipt, holding and disposition of the CVRs and the receipt of payments thereunder, and to review the discussion under the heading “Certain Canadian Federal Income Tax Considerations”.

Fusion’s business relationships may be subject to disruption due to uncertainty associated with the Arrangement.

Parties with which Fusion currently does business or may do business in the future may experience uncertainty associated with the Arrangement, including with respect to current or future business relationships with Fusion, Parent or Purchaser. Such uncertainty could be materially adverse to the business, financial condition, results of operations or prospects of Fusion.

While the Arrangement is pending, Fusion is restricted from taking certain actions.

The Arrangement Agreement restricts Fusion from taking specified actions without the consent of Parent until the Arrangement is completed. These restrictions may prevent Fusion from pursuing attractive business opportunities that may arise prior to the completion of the Arrangement. Such restrictions include those items detailed in the section entitled “The Arrangement Agreement—Covenants—Conduct of Business of Fusion” and “The Arrangement Agreement—Covenants—Restrictions on Solicitation of Other Offers”.

Certain directors and executive officers of Fusion may have interests in the Arrangement that may be different from, or in addition to, the interests of Shareholders generally.

Certain directors and officers of Fusion may have interests in the Arrangement that may be different from, or in addition to, the interests of Shareholders generally, including those interests discussed under the heading “The Arrangement —Interests of Fusion’s Directors and Officers in the Arrangement”. In considering the recommendation of the Board to vote in favour of the Arrangement Resolution, Shareholders should consider these interests.

Completion of the Arrangement is subject to the Required Shareholder Approval.

There can be no certainty, nor can Fusion provide assurance, that the Required Shareholder Approval will be obtained. If such approval is not obtained and the Arrangement is not completed, the market price of the Shares may decline to the extent that the current market price reflects a market assumption that the Arrangement will be completed. If the Arrangement is not completed and the Board decides to seek another arrangement or alternative transaction, there can be no assurance that it will be able to find a party willing to pay an equivalent or greater price for the Shares than the Consideration to be paid pursuant to the Arrangement.

Applicable tax authorities may not agree with the discussion regarding tax matters included in this Circular.

There can be no assurance that the Canada Revenue Agency, the U.S. tax authorities or other applicable taxing authorities will agree with the disclosure regarding Canadian federal income tax and the U.S. tax consequences of the Arrangement, as applicable, as set forth in this Circular.

Fusion will continue to face a number of risks regarding its business and prospects if the Arrangement is not completed.

If the Arrangement is not completed, Fusion will continue to face the risks that it currently faces with respect to its affairs, business and operations and future prospects. Such risks include those set forth and described in the “Risk Factors” sections of Fusion’s most recent Annual Report on Form 10-K and Quarterly Reports on Form 10-Qs, and other documents filed with the SEC and the Canadian Securities Administrators, copies of which can be found under Fusion’s profile on SEDAR+ at www.sedarplus.com and EDGAR at www.sec.gov/edgar.

PROCEDURES FOR SURRENDER OF SHARES AND RECEIPT OF CONSIDERATION

Procedures for Surrender of Certificates by Shareholders

From and after the Effective Time, all certificates or book-entry holdings that represented the Shares immediately prior to the Effective Time will cease to represent any rights with respect to such Shares, and will only represent the right to receive the Consideration or, in the case of the Dissenting Shareholders, the right to receive fair value for their Shares.

Enclosed with this Circular is a form of Letter of Transmittal which, when properly completed and duly executed and returned together with any certificate or certificates representing Shares and all other required documents, will enable each registered Shareholder (other than Dissenting Shareholders) to obtain the Consideration that such registered Shareholder is entitled to receive under the Arrangement.

The form of Letter of Transmittal contains complete instructions on how to exchange the certificate(s) representing the Shares for the Consideration under the Arrangement. A registered Shareholder will not receive Consideration under the Arrangement until after the Arrangement is completed and the registered Shareholder has returned their properly completed documents, including the Letter of Transmittal and any certificate(s) representing the Shares to the Depositary.

Only registered Shareholders are required to submit a Letter of Transmittal. A Beneficial Shareholder holding Shares through an Intermediary should contact that Intermediary for instructions and assistance in depositing their Shares and carefully follow any instructions provided by such Intermediary.

Upon the surrender by a registered Shareholder to the Depositary for cancellation of a certificate which immediately prior to the Effective Time represented outstanding Shares together with a duly completed and executed Letter of Transmittal and such additional documents and instruments as the Depositary may reasonably require, the Depositary shall deliver to such registered Shareholder a cheque, wire or other form of immediately available funds representing the Consideration which such registered Shareholder has the right to receive under the Plan of Arrangement for such Shares less any amounts withheld pursuant to the Plan of Arrangement, and any certificate so surrendered shall forthwith be cancelled. Upon receipt of a customary “agent’s message” by the Depositary with respect to book-entry Shares, and such additional documents and instruments as the Depositary may reasonably require, the Depositary shall deliver to the holder of such book-entry Shares, a cheque, wire or other form of immediately available funds representing the Consideration that such holder has the right to receive under the Arrangement for such book-entry Shares, less any amounts withheld pursuant to the Plan of Arrangement, and any book-entry Shares so surrendered shall forthwith be cancelled.

No registered Shareholder shall be entitled to receive any consideration with respect to such Shares other than any cash payment to which such holder is entitled to receive in accordance with the Plan of Arrangement and no such registered Shareholder will be entitled to receive any interest, dividends, premium or other payment in connection therewith.

The method of delivery of certificates representing Shares and all other required documents is at the option and risk of the registered Shareholder depositing their Shares. Any use of mail to transmit certificate(s) representing Shares and the Letter of Transmittal is at each registered Shareholder’s risk and documents so mailed shall be deemed to have been received by Fusion upon actual receipt by the Depositary. Fusion recommends that such certificate(s) and other documents be delivered by hand to the Depositary and a receipt therefore be obtained or that registered mail be used (with proper acknowledgment) and appropriate insurance be obtained.

In the event any certificate which immediately prior to the Effective Time represented one or more outstanding Shares that were transferred pursuant to the Plan of Arrangement shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such certificate to be lost, stolen or

destroyed, the Depositary will issue in exchange for such lost, stolen or destroyed certificate, a cheque, wire or other form of immediately available funds for the Consideration that such Shareholder has the right to receive in accordance with the Plan of Arrangement and such Shareholder’s Letter of Transmittal. When authorizing such payment in exchange for any lost, stolen or destroyed certificate, the person to whom such cash is to be delivered shall as a condition precedent to the delivery of such payment, give a bond satisfactory to Purchaser and the Depositary (each acting reasonably) in such sum as Purchaser may direct, or otherwise indemnify Purchaser and Fusion in a manner satisfactory to Purchaser and Fusion (each acting reasonably) against any claim that may be made against Purchaser and Fusion with respect to the certificate alleged to have been lost, stolen or destroyed.

Cancellation of Rights

Until surrendered to the Depositary in accordance with the Plan of Arrangement, each certificate that immediately prior to the Effective Time represented Shares shall be deemed after the Effective Time to represent only the right to receive upon such surrender the Consideration which the holder is entitled to receive in lieu of such certificate, less any amounts withheld in accordance with the Plan of Arrangement. Any such certificate formerly representing Shares not duly surrendered on or before the sixth anniversary of the Effective Date shall cease to represent a claim by or interest of any former holder of Shares of any kind or nature against or in Fusion. On such date, the Consideration to which such former holder was entitled shall be deemed to have been surrendered to Purchaser or Fusion, as applicable, and shall be paid over by the Depositary or the Rights Agent, as applicable, to Purchaser or as directed by Purchaser.

Any payment made by way of cheque by the Depositary (or Fusion, if applicable) pursuant to the Plan of Arrangement that has not been deposited or has been returned to the Depositary (or Fusion) or that otherwise remains unclaimed, in each case, on the sixth anniversary of the Effective Time, and any right or claim to payment hereunder that remains outstanding on the sixth anniversary of the Effective Time shall cease to represent a right or claim of any kind or nature and the right of the holder to receive the applicable consideration for the Securities pursuant to this Plan of Arrangement shall terminate and be deemed to be surrendered and forfeited to Purchaser or Fusion, as applicable, for no consideration.

Payment of Consideration by Purchaser

Purchaser and Parent will, prior to the Effective Time, provide or cause to be provided to the Depositary with sufficient cash (to be held in escrow until the Effective Time (the terms and conditions of such escrow to be satisfactory to Fusion and Parent, each acting reasonably)) to satisfy the aggregate Consideration payable pursuant to the Plan of Arrangement and, pursuant to a depositary agreement with the Depositary, by wire transfer to be initiated prior to the Effective Time.

Depositary Services

The Depositary will formally be appointed to act as depositary for the Arrangement for the receipt of certificates representing Shares and the Letter of Transmittal and for the purposes of delivering the Consideration payable to Shareholders. The terms and conditions of such appointment will be set out in an agreement to be entered into prior to the Effective Date. The Depositary will receive reasonable and customary compensation for its services in connection with the Arrangement, will be reimbursed for certain out-of-pocket expenses and will be indemnified by Fusion, Parent and Purchaser against certain liabilities and expenses in connection therewith.

DISSENT RIGHTS

The following description of the rights of Shareholders wishing to exercise Dissent Rights is not a comprehensive statement of the procedures to be followed by a Dissenting Shareholder who seeks payment of the fair value of its Shares and is qualified in its entirety by the reference to the full text of Section 190 of the CBCA, which is set forth in Appendix F of this Circular, as modified by the Interim Order, a copy of which is attached to this Circular as Appendix D and the Plan of Arrangement, a copy of which is attached as Appendix C to this Circular. The statutory procedures dealing with the right of dissent are technical and complex. A Shareholder who intends to exercise Dissent Rights should carefully consider and comply with the provisions of Section 190 of the CBCA, as modified by the Interim Order and the Plan of Arrangement and seek legal advice. Failure to comply with the provisions of the CBCA, as so modified by the Interim Order and the Plan of Arrangement, and to adhere to the procedures established therein may result in the loss of all rights thereunder.

Pursuant to the Plan of Arrangement and the Interim Order, registered Shareholders who comply with the procedures set out in Section 190 of the CBCA, as modified by the Plan of Arrangement and the Interim Order, are entitled to dissent in respect of the Arrangement Resolution. Set out below is a summary of the provisions of Section 190 of the CBCA, as modified by the Plan of Arrangement and the Interim Order, relating to a Shareholder’s Dissent Rights.

The Court hearing the application for the Final Order has the discretion to alter the Dissent Rights described herein based on the evidence presented at such hearing.

The Interim Order expressly provides registered Shareholders with the right to dissent with respect to the Arrangement Resolution. Each Dissenting Shareholder will be entitled to be paid the fair value for Shares held by such Dissenting Shareholder, which fair value, notwithstanding anything to the contrary contained in the CBCA shall be determined as of the close of business on the day before the Arrangement Resolution was adopted at the Meeting. The Dissenting Shareholder will not be entitled to the Consideration that would have been payable to such Shareholder if such Shareholder had not exercised their Dissent Rights in respect of such Shares.

A registered Shareholder who wishes to dissent must ensure that a written notice of objection to the Arrangement Resolution is received by Fusion at its office located at 270 Longwood Road South, Hamilton, Ontario, Canada, L8P 0A6, Attention: Chief Legal Officer, with a copy to Fusion’s Canadian legal counsel, Osler, Hoskin & Harcourt LLP, 100 King Street West, Suite 6200, P.O. Box 50, Toronto, Ontario, Canada, M5X 1B8, Attention: Alex Gorka and Brett Anderson, not later than 5 p.m. (Eastern time) on the day that is two Business Days immediately preceding the date of the Meeting (as it may be adjourned or postponed from time to time). Any Dissenting Shareholder should seek independent legal advice, as failure to comply strictly with the provisions of Section 190, as modified by the Plan of Arrangement and Interim Order, may result in the loss of all Dissent Rights.

Dissenting Shareholders who validly withdraw their Dissent Rights or who are ultimately determined not to be entitled, for any reason, to be paid fair value for their Shares will be deemed to have participated in the Arrangement on the same basis as a non-Dissenting Shareholder and shall be entitled to receive (1) a cash payment of $21.00 for each Share and (2) one CVR per Share formerly held by them in accordance with the Plan of Arrangement. In addition to any other restrictions under Section 190 of the CBCA, (1) Shareholders who vote in favour of the Arrangement Resolution or have instructed a proxyholder to vote such Shares in favour of the Arrangement Resolution, or (2) a Shareholder who seeks to exercise Dissent Rights with respect to less than all of the Shares held by such Shareholder, shall not be entitled to exercise Dissent Rights and shall be deemed to have not exercised Dissent Rights in respect of such Shares.

In no circumstances shall Fusion, Purchaser, Parent or any of their respective successors or any other person be required to recognize a person exercising Dissent Rights unless such person (1) is the registered holder of those Shares in respect of which such rights are sought to be exercised, (2) has voted, or instructed a proxyholder

100

to vote, such Shares against the Arrangement Resolution, and (3) has strictly complied with the procedure for exercising Dissent Rights and has not withdrawn such dissent prior to the Effective Time. In no case shall Fusion, Purchaser, Parent, the Transfer Agent, the Depositary or any other person be required to recognize a Dissenting Shareholder as a holder of Shares after the completion of the transfer contemplated by the Plan of Arrangement, and the name of each Dissenting Shareholder shall be deleted from the register of holders of Shares as at the time those Shares are so transferred and such Shares will be cancelled.

Section 190 of the CBCA

A brief summary of the provisions of Section 190 of the CBCA as modified by the Interim Order and Plan of Arrangement is set out below. This summary is qualified in its entirety by the provisions of Section 190 of the CBCA, the Interim Order and the Plan of Arrangement, the full text of which are set forth in Appendix F, D, and C to this Circular, respectively.

Registered Shareholders may exercise a Dissent Right in respect of the Arrangement and require Fusion to purchase the Shares held by such Shareholders at the fair value of such Shares.

The exercise of Dissent Rights does not deprive a registered Shareholder of the right to vote at the Meeting. However, a Shareholder is not entitled to exercise Dissent Rights in respect of the Arrangement Resolution if such holder votes any of the Shares beneficially held by such holder in favour of the Arrangement Resolution.

A Dissenting Shareholder is required to send a written objection to the Arrangement Resolution to Fusion prior to the Meeting, in accordance with the dissent procedure set forth above. The execution or exercise of a proxy against the Arrangement Resolution, a vote against the Arrangement Resolution or not voting on the Arrangement Resolution does not constitute a written objection for purposes of the right to dissent under Section 190 of the CBCA. Within 10 days after the Arrangement Resolution is approved by Shareholders, Fusion must send to each Dissenting Shareholder a notice that the Arrangement Resolution has been adopted, setting out the rights of the Dissenting Shareholder and the procedures to be followed on exercise of those rights. The Dissenting Shareholder is then required, within 20 days after receipt of such notice (or if such Shareholder does not receive such notice, within 20 days after learning of the adoption of the Arrangement Resolution), to send to Fusion a written notice containing the Dissenting Shareholder’s name and address, the number of Shares in respect of which the Dissenting Shareholder dissents and a demand for payment of the fair value of such Shares and, within 30 days after sending such written notice, to send to Fusion or the Transfer Agent the appropriate certificate(s) representing the Shares in respect of which the Dissenting Shareholder has exercised Dissent Rights. A Dissenting Shareholder who fails to send to Fusion within the required periods of time the required notices or the certificates representing the Shares in respect of which the Dissenting Shareholder has dissented may forfeit its Dissent Rights.

If the matters provided for in the Arrangement Resolution become effective, then Fusion will be required to send, not later than seven days after the later of: (1) the Effective Date; or (2) the day the demand for payment is received by Fusion, to each Dissenting Shareholder whose demand for payment has been received, a written offer to pay for the Shares of such Dissenting Shareholder in such amount as the trustees of Fusion consider to be the fair value thereof accompanied by a statement showing how the fair value was determined unless there are reasonable grounds for believing that Fusion is, or after the payment would be, unable to pay its liabilities as they become due or the realizable value of Fusion assets would thereby be less than the aggregate of its liabilities. Under the Plan of Arrangement, Fusion will be required to pay the fair value of such Shares held by a Dissenting Shareholder and to offer and pay the amount to which such holder is entitled. Such payment is to be made, pursuant to Section 190 of the CBCA, within ten days after an offer made as described above has been accepted by a Dissenting Shareholder, but any such offer lapses if Fusion does not receive an acceptance thereof within 30 days after such offer has been made. If such offer is not made or accepted within 50 days after the Effective Date, Fusion may apply to a court of competent jurisdiction to fix the fair value of such Shares. There is no obligation of Fusion to apply to the court. If Fusion fails to make such an application, a Dissenting Shareholder has the right to so apply within a further 20 days.

101

PROPOSALS SUBMITTED FOR CONSIDERATION AT THE MEETING

Proposal 1: The Arrangement Resolution

Fusion is asking its Shareholders to approve the Arrangement Resolution, a copy of which is attached as Appendix B to this Circular. For a summary and detailed information regarding this proposal, see the information about the Arrangement Agreement and the Arrangement throughout this Circular, including the information in the sections entitled “The Arrangement” and “The Arrangement Agreement”. Copies of the Arrangement Agreement and the Plan of Arrangement are attached as Appendix A and Appendix C, respectively, to this Circular. We urge you to read the full text of the Arrangement Agreement and Plan of Arrangement.

Pursuant to the CBCA and the Interim Order, in order for the Arrangement Resolution to become effective, the Arrangement Resolution must be passed by (1) an affirmative vote of not less than 66²⁄₃% of the votes cast on the Arrangement Resolution by the Shareholders, present in person or represented by proxy at the Meeting, each being entitled to one vote per Share and (2) an affirmative vote of a majority of the votes cast by the Shareholders present in person or represented by proxy at the Meeting, each being entitled to one vote per Share, after excluding the votes of those Persons whose votes are required to be excluded under MI 61-101.

Abstentions, the failure to vote and broker non-votes, if any, will have no effect on the outcome of this proposal. Broker non-votes are shares held by a broker or other nominee that are present in person or represented at a meeting, but with respect to which the broker or other nominee is not instructed by the beneficial owner of such shares to vote on the particular proposal and the broker does not have discretionary voting power on such proposal.

If you sign and return a proxy and do not indicate how you wish to vote on the Arrangement Resolution, your Shares will be voted in favour of the proposal.

The Board unanimously recommends that Shareholders vote “FOR” the Arrangement Resolution.

Proposal 2: The Bylaw Proposal

Shareholders are being asked to cast a confirmatory vote on an amendment to Fusion’s bylaws (the “Bylaw Proposal”). On March 18, 2024, the Board adopted an amendment (the “Bylaw Amendment”) to Fusion’s bylaws (as may be amended from time to time, the “Bylaws”) that amended and restated Section 10.8 of the Bylaws to specify that, unless Fusion consents in writing to the selection of an alternative forum, (1) the sole and exclusive forum for certain legal actions involving Fusion will be the courts of the Province of Ontario and (2) the sole and exclusive forum for certain legal actions filed in the United States asserting a cause of action arising under the Securities Act of 1933, as amended, will be the United States District Court for the District of Delaware.

Pursuant to the CBCA, the Bylaw Amendment became effective immediately upon the adoption by the Board; provided that the Bylaw Amendment be submitted to the Shareholders for confirmation at the next meeting of the Shareholders, and if the Shareholders reject the Bylaw Amendment at such meeting, the Bylaw Amendment will cease to be effective upon the conclusion of such meeting.

The Bylaw Amendment is intended to provide a streamlined, efficient and organized process for resolution of disputes. Additionally, the background and experience of the U.S. federal district courts in Delaware resolving issues under the U.S. Securities Act, place these courts in the best positions to resolve claims arising under the applicable bodies of law. Accordingly, the Board believes that the exclusive forum provisions are a prudent and proactive means for managing these types of potential litigation and promote efficient and consistent resolutions in the event these types of litigation arise. Although some plaintiffs might prefer to litigate these matters in different jurisdictions, the Board believes that the substantial benefits to Fusion and its shareholders outweigh these concerns.

102

Accordingly, Shareholders are being asked to cast a confirmatory vote at the Meeting to adopt of the following resolution:

“BE IT RESOLVED THAT:

The amendment to Section 10.8 of Fusion’s by-laws providing that, unless Fusion consents in writing to the selection of an alternative forum, (1) the sole and exclusive forum for certain legal actions involving Fusion will be the courts of the Province of Ontario and (2) the sole and exclusive forum for certain legal actions filed in the United States asserting a cause of action arising under the Securities Act of 1933, as amended, will be the United States District Court for the District of Delaware, as adopted by the Board on March 18, 2024, is hereby confirmed.”

The vote on the Bylaw Proposal is a vote separate and apart from the vote on the Arrangement Resolution, and such Bylaw Proposal is not a condition to the completion of the Arrangement. Accordingly, you may vote to approve the Arrangement Resolution and vote not to approve the Bylaw Proposal, and vice versa.

Approval of the Bylaw Proposal requires the affirmative vote of a majority of the votes cast by the Shareholders present in person or represented by proxy at the Meeting, each being entitled to one vote per Share. Abstentions, the failure to vote your Shares and broker non-votes, if any, will have no effect on the outcome of the Bylaw Proposal. If you sign and return a proxy and do not indicate how you wish to vote on the named Bylaw Proposal, your Shares will be voted in favour of the proposal.

The Board unanimously recommends that holders of Shares vote “FOR” the Bylaw Proposal.

Other Matters

Other Matters for Action at the Meeting. As of the date of this Circular, the Board knows of no matters that will be presented for consideration at the Meeting other than as described in this Circular.

Adjournments or Postponements of the Meeting. Subject to the terms of the Arrangement Agreement, the Meeting may be adjourned from time to time and from place to place by the chair of the Meeting or the chairperson of the Board. Under Fusion’s Bylaws, if the Meeting is adjourned for less than 30 days, it is not necessary to give notice of the adjourned meeting, other than by announcement at the time of an adjournment. If the Meeting is adjourned by one or more adjournments for an aggregate of 30 days or more, notice of the adjourned meeting shall be given as for an original meeting.

Future Shareholder Proposals. If the Arrangement is consummated, we will not have public shareholders and there will be no public participation in any future meeting of shareholders. However, if the Arrangement is not completed, we expect to hold a 2024 Annual Meeting of Shareholders. In addition to complying with the advanced notice provisions included in our Articles, which required that proposals be received no later than January 29, 2024, which is 90 days before the anniversary date of the notice of meeting for the 2023 Annual Meeting of Shareholders, a Shareholder who would like to have a proposal considered for inclusion in our 2024 proxy statement must have submitted the proposal in accordance with the procedures outlined in Rule 14a-8 of the Exchange Act so that it was received by us no later than December 29, 2023, which is 120 days prior to the first anniversary of the mailing date of the proxy statement for our 2023 Annual Meeting of Shareholders. However, if the date of the 2024 Annual Meeting is changed by more than 30 days from the anniversary of our 2023 Annual Meeting of Shareholders, then the deadline is a reasonable time before we begin to print and send our proxy statement for the 2024 Annual Meeting of Shareholders. SEC rules set standards for eligibility and specify the types of shareholder proposals that may be excluded from a proxy statement. In addition, shareholders who would like to solicit proxies in support of director nominees other than our nominees must provide notice that sets forth the information required by Rule 14a-19 of the Exchange Act no later than April 15, 2024. Shareholder proposals should be addressed to Fusion Pharmaceuticals Inc., 270 Longwood Road South, Hamilton, ON, L8P 0A6 Canada, Attention: Chief Legal Counsel and Secretary.

109

Householding of Special Meeting Materials. The SEC has adopted rules that permit companies and intermediaries, such as brokers and banks, to satisfy the delivery requirements for information circular and proxy statements with respect to two or more shareholders sharing an address by delivering a single information circular and proxy statement, as applicable, addressed to those shareholders, unless contrary instructions have been received. This procedure, which is commonly referred to as “householding,” reduces the amount of duplicate information that shareholders receive and lowers printing and mailing costs for companies.

Certain brokerage firms may have instituted householding for beneficial owners of Shares held through brokerage firms. If your family has multiple accounts holding Shares, you may have already received a householding notification from your broker. You may decide at any time to revoke your decision to household, and thereby receive multiple copies of proxy materials. If you wish to opt out of this procedure and receive a separate set of proxy materials in the future, or if you are receiving multiple copies and would like to receive only one, you should contact your broker, trustee or other nominee or Fusion at the address and telephone number below. A separate copy of these proxy materials will be promptly delivered upon request by writing to: Fusion Pharmaceuticals Inc., 270 Longwood Road South, Hamilton, ON, L8P 0A6 Canada, Attention: Chief Legal Officer and Secretary. Requests can also be made by calling (289) 799-0891.

Additional Information

Additional financial and other information relating to Fusion is included in its audited annual and unaudited quarterly consolidated financial statements, annual and quarterly management discussion and analysis, annual information form, annual report on Form 10-K for the year ended December 31, 2023, and other continuous disclosure documents, which are available on the SEC’s website at www.sec.gov or on SEDAR+ at www.sedarplus.com. In addition, copies of Fusion’s most recent annual report, financial statements and management information circular and proxy statement, as filed with the SEC and available on EDGAR and SEDAR+, may be obtained without charge from Fusion upon request.

GENERAL PROXY MATTERS

Solicitation of Proxies

This Circular is furnished in connection with the solicitation of proxies by and on behalf of Fusion’s management to be used at the Meeting. Solicitations of proxies will be primarily by mail, but may also be by telephone, e-mail, facsimile and in person communication by directors, officers or employees of Fusion.

Fusion has also retained Innisfree to assist it in connection with communicating to Shareholders in respect of the Arrangement. In connection with these services, Innisfree is expected to receive a fee of $40,000 and will be reimbursed for its reasonable out-of-pocket expenses. The entire cost of the solicitation will be borne by Fusion. In addition, Fusion will reimburse banks, brokers and other nominees representing Beneficial Shareholders for their expenses in forwarding soliciting materials to such Beneficial Shareholders. Proxies may also be solicited by Fusion’s directors, officers and employees, personally or by telephone, email, fax, over the Internet or other means of communication. No additional compensation will be paid for such services. See Appendix G “Voting Information” for additional information.

Appointment and Revocation of Proxies

If you are a registered Shareholder and are unable to attend the Meeting, please vote your shares prior to the meeting. Instructions on how to complete and return your proxy are included in the form of proxy and in this Circular. You may choose the named proxyholders named in the accompanying form of proxy to be your proxyholder or, alternatively, you may appoint another person or company to be your proxyholder. To exercise such right, the names of the named proxyholders should be crossed out and the name of the registered Shareholder’s appointee should be legibly printed in the blank space provided. The form of proxy must be executed by the registered Shareholder or his or her attorney authorized in writing, or if the registered Shareholder is a corporation, under its corporate seal by a duly authorized officer or attorney of Fusion. If the Shares are registered in more than one name, all registered persons must sign the proxy form. If the Shares registered in a company’s name or any name other than your own, you must provide documents showing your authorization to sign the proxy form for that company or name.

The proxy form must be completed and returned in accordance with the instructions on the proxy card. If you plan to vote during the meeting through the internet, you must register in advance at the site https://www.proxydocs.com/FUSN and log into the virtual meeting platform during the Meeting using the unique link provided to you via email following the completion of your registration. If you plan to vote by telephone, you can call 1-866-834-5856. It is recommended to vote your Shares in advance of the meeting by following the instructions on https://www.proxydocs.com/FUSN. Late proxies may be accepted or rejected by the Chair of the Meeting in his or her discretion, and the Chair of the Meeting is under no obligation to accept or reject any later proxy. Late proxies may be accepted or rejected by the Chair of the Meeting in his or her discretion, and the Chair of the Meeting is under no obligation to accept or reject any later proxy.

Unless you choose another person or company to be your proxyholder, you are giving the named proxyholders named on the form of proxy the authority to vote your Shares at the Meeting or at any adjournments or postponements of the Meeting.

If a registered Shareholder who has submitted a proxy attends the virtual Meeting and submits a new proxy at the Meeting, any votes cast by such registered Shareholder on a ballot at the Meeting will be counted and the previously submitted proxy will be disregarded.

111

Signature of Proxy

The form of proxy must be executed by the registered Shareholder or his or her attorney authorized in writing, or if the registered Shareholder is a corporation, under its corporate seal by a duly authorized officer or attorney of Fusion. If the Shares are registered in more than one name, all registered persons must sign the proxy form. If the Shares are registered in a company’s name or any name other than your own, you must provide documents showing your authorization to sign the proxy form for that company or name.

A proxy signed by a person acting as attorney, executor, administrator or trustee, or in some other representative capacity, should reflect such person’s full title as such.

Voting of Proxies

The Shares represented by a duly submitted proxy or voting instruction form will be voted at the Meeting by a validly named proxyholder or the named proxyholders in accordance with the instructions set forth in the completed form of proxy or voting instruction form.

In the absence of such instructions: (1) the named proxyholder may decide how to vote the Shares at the Meeting in lieu of the named proxyholders; and (2) if your proxyholder is one of the named proxyholders, such named proxyholder will vote “FOR” the Arrangement Resolution and the other proposals set forth in the Notice for the Meeting.

Signing the enclosed form of proxy or voting instruction form gives authority to the validly named proxyholder or the named proxyholders to vote the Shares governed by such proxy at the Meeting in accordance with the instructions provided therein.

Exercise of Discretion of Proxy

The persons named in your proxy or voting instruction form will have discretionary authority with respect to amendments or variations to matters identified in the Notice of Special Meeting and with respect to other matters which may properly come before the Meeting. At the time of printing of this Circular, management knows of no such amendments, variations or other matters to come before the Meeting. However, if any such amendments, variations or other matters which are not now known to management should properly come before the Meeting, the persons named in the form of proxy will vote on such other business in accordance with their best judgment.

Voting Shares and Principal Holders Thereof

As of the Record Date, there were 84,965,608 Shares outstanding.

To the knowledge of the directors and officers of Fusion, as at the date hereof, no person or company beneficially owns, directly or indirectly, or exercises control or direction, over more than 10% of the voting rights attached to any class of voting securities of Fusion.

Advice for Beneficial Shareholders

The information set forth in this section is provided to Beneficial Shareholders. Beneficial Shareholders should note that only proxies deposited by registered Shareholders whose names appear on our records as the registered holders of Shares can be recognized and acted upon at the Meeting. If the Shares are listed in an

112

account statement provided to a Beneficial Shareholder by an Intermediary, then in almost all cases those Shares will not be registered in the Beneficial Shareholder’s name on the records maintained by Fusion or the Transfer Agent. Such Shares will more likely be registered under the name of the Beneficial Shareholder’s Intermediary or an agent of that Intermediary. In Canada, the vast majority of such Shares are registered under the name of CDS & Co. (the registration name for CDS Clearing and Depository Services Inc., which acts as nominee for many Canadian brokerage firms). In the U.S., these Shares are registered under the name of Cede & Co. (the nominee of the Depository Trust Company (“DTC”), which processes transfers of stock certificates on behalf of the DTC). Shares held by Intermediaries or their nominees can only be voted upon the instructions of the Beneficial Shareholder. Without specific instructions, the Intermediaries or nominees are generally prohibited from voting securities for their clients. Fusion does not know for whose benefit the Shares registered in the name of Cede & Co. are held. Therefore, Beneficial Shareholders cannot be recognized at the Meeting for the purposes of voting the Shares in person or by way of proxy except as set forth below.

Applicable regulatory policy requires Intermediaries to seek voting instructions from Beneficial Shareholders in advance of meetings in which they are able to vote. Every Intermediary has its own mailing procedures and provides its own return instructions, which should be carefully followed by Beneficial Shareholders in order to ensure that their Shares are voted at the Meeting. Often, the form of proxy supplied to a Beneficial Shareholder by its Intermediary is identical to the form of proxy provided to registered Shareholders; however, its purpose is limited to instructing the Intermediary how to vote on behalf of the Beneficial Shareholder. The majority of Intermediaries now delegate responsibility for obtaining instructions from clients to Broadridge Investor Communication Solutions (Broadridge) in the United States and Canada. Broadridge typically applies a special sticker to proxy forms, mails those forms to the Beneficial Shareholders and requests the Beneficial Shareholders to return the proxy forms to Broadridge. Broadridge then tabulates the results of all instructions received and provides appropriate instructions respecting the voting of Shares to be represented at the Meeting. A Beneficial Shareholder receiving a proxy from Broadridge cannot use that proxy to vote Shares directly at the Meeting as the proxy must be returned as directed by Broadridge well in advance of the Meeting in order to have the Shares voted at the Meeting.

Although a Beneficial Shareholder may not be recognized directly at the Meeting for the purposes of voting Shares registered in the name of his, her or its Intermediary (or agent of the Intermediary), a Beneficial Shareholder may attend at the Meeting as proxyholder for the Intermediary (likely the registered Shareholder) and vote Shares in that capacity.

Beneficial Shareholders who wish to attend the Meeting and indirectly vote their Shares as proxyholder for the registered Shareholder should enter their own name in the blank space on the form of proxy provided to them and return the same to their Intermediary (or the Intermediary’s agent) in accordance with the instructions provided by such Intermediary (or agent), well in advance of the Meeting.

Beneficial Shareholders should contact their Intermediary through which they hold Shares and obtain instructions regarding the procedure for the revocation of any voting or proxyholder instructions previously provided to that Intermediary.

is not, in the reasonable opinion of the Corporation, prejudicial to (i) the Corporation and its Subsidiaries, or (ii) the Shareholders, in each case of (i) and (ii), taken as a whole;

(c)

does not reduce the Consideration or change the form of Consideration to be received by the Shareholders or affect or modify the timing of payment of the Consideration by Parent;

(d)

would not result in any Taxes being imposed on, or any adverse Tax consequences to, the Shareholders or Incentive Holders greater than the Taxes to the Shareholders or Incentive Holders in connection with the Arrangement in the absence of any Pre-Closing Reorganization;

does not interfere with the ongoing operations of the Corporation or any of its Subsidiaries in any material respect;

Upon receipt of such notice, the Corporation and each Subsidiary, as applicable, shall work cooperatively with the Parent and use their commercially reasonable efforts to, prior to the Effective Time, do such acts and things as are necessary to give effect to such Pre-Closing Reorganization, including any amendment to this Agreement or the Plan of Arrangement.

(3) The Parent agrees that it will be responsible for all reasonable out-of-pocket Corporation costs and expenses (including reasonable out-of-pocket professional fees and expenses) in connection with any Pre-Closing Reorganization to be carried out at its request.

(4) The Parent agrees that it will be responsible to prepare, prior to the Effective Time, all documentation necessary to give effect to any Pre-Closing Reorganization. Upon request by the Corporation, the Parent agrees that it will promptly provide the Corporation with the documentation necessary to give effect to any Pre-Closing Reorganization before the Effective Time.

(5) Each Party agrees that any transactions in connection with the Pre-Closing Reorganization or the Corporation’s cooperation contemplated by this Section 4.20, will not be considered in determining whether a representation, warranty or covenant of the Corporation or the Subsidiary undertaking such Pre-Closing Reorganization under this Agreement or the Plan of Arrangement has been breached (including where any such Pre-Closing Reorganization requires the consent of any third party under a Contract).

(6) If the Plan of Arrangement is not completed, the Parent shall indemnify and hold harmless the Corporation, its Subsidiaries and their respective officers, directors and employees (to the extent such persons are assessed with any statutory liability) for all direct and indirect costs or losses, liabilities, damages, claims, interest awards, judgements and penalties and out-of-pocket costs and expenses (including any professional fees and expenses and taxes) actually incurred or suffered by the Corporation, its Subsidiaries and their respective officers, directors and employees, in connection with, arising from or as a result of effecting all or any part of or the reversal or unwinding of any Pre-Closing Reorganization.

(7) Notwithstanding anything to the contrary in this Section 4.20, the rights and obligations in this Section 4.20 shall not override the rights and obligations of the parties under Section 4.12.

(a)

(b)

such Acquisition Proposal did not arise as a result of a violation by the Corporation directly or indirectly through its Subsidiaries or its or their respective Representatives of this Article 5 in any

A-47

material respect, and the Corporation has been and continues to be in compliance with its obligations under this Article 5, in all material respects;

(c)

the Corporation enters into a customary confidentiality and standstill agreement with such Person having terms at least as onerous in all material respects as those set forth in the Confidentiality Agreement (it being agreed that such confidentiality agreement need not prohibit the making of an Acquisition Proposal confidentially to the Board);

(d)

the Corporation has provided the Parent with (i) written notice stating the Corporation’s intention to participate in such discussions or negotiations and to provide all such copies, access or disclosure relating to the Acquisition Proposal, including the identity of the party making such Acquisition Proposal; and (ii) a copy of the confidentiality and standstill agreement referred to in Section 5.3(1)(c) above; and

(e)

the Corporation provides the Parent with any non-public information provided to such other Person which was not previously provided to the Parent substantially concurrently with such information being provided to such Person.

Section 5.4 Right to Match.

(1) If at any time following the date of this Agreement and prior to obtaining the Required Shareholder Approval at the Meeting, the Corporation receives an unsolicited bona fide written Acquisition Proposal that constitutes a Superior Proposal, the Board may authorize the Corporation to make a Change in Recommendation or enter into a definitive agreement with respect to such Acquisition Proposal, if and only if:

(a)

such Superior Proposal did not arise as a result of a violation by the Corporation directly or indirectly through its Subsidiaries or its or their respective Representatives of this Article 5 in any material respect, and the Corporation has been and continues to be in compliance with its obligations under this Article 5 in all material respects;

(b)

the Corporation has provided the Parent with written notice detailing the determination of the Board that such Acquisition Proposal constitutes a Superior Proposal and of the intention of the Board to enter into such definitive agreement (the Superior Proposal Notice);

(c)

the Corporation has provided the Parent with an unredacted copy of the proposed definitive agreement for the Superior Proposal and all schedules and exhibits thereto, together with any financing documents supplied to the Corporation in connection therewith;

(d)

four (4) Business Days (the Matching Period) shall have elapsed from the date that is the later of the date on which the Parent received the Superior Proposal Notice and the date on which the Parent received all of the materials set forth in Section 5.4(1)(c) above (it being understood that the Corporation shall promptly, and in any event within twenty four (24) hours, inform the Parent of any amendment to the financial or other material terms of such Superior Proposal during such period);

(e)

after the Matching Period and subject to the Corporation’s compliance with Section 5.4(2), the Board has determined in good faith, after consultation with its outside legal counsel and financial advisors, that such Acquisition Proposal continues to constitute a Superior Proposal, if applicable, compared to the terms of the Arrangement as proposed to be revised by the Parent under Section 5.4(2);

(f)

after the Matching Period, the Board has determined, in good faith, after consultation with its outside legal counsel, that failure of the Board to make a Change in Recommendation or to enter into a definitive agreement with respect to such Superior Proposal would be inconsistent with its fiduciary duties; and

(g)

prior to or concurrently with entering into a definitive agreement with respect to such Superior Proposal, the Corporation validly terminates this Agreement pursuant to Section 7.2(3)(b) and pays the Corporation Termination Fee in full pursuant to Section 7.3.

A-48

(2) During the Matching Period, or such longer period as the Corporation may approve in writing for such purpose: (a) the Corporation shall negotiate (and direct its Representatives to negotiate) in good faith with the Parent and its Representatives (to the extent the Parent desires to negotiate); and (b) the Parent shall have the right, but not the obligation, to propose revisions to the terms of this Agreement and the Arrangement; and (c) the Board shall review any such proposed revisions to the terms of this Agreement and the Arrangement in good faith in order to determine, in consultation with its financial and outside legal advisors, whether such revisions, if given effect, would cause the Superior Proposal giving rise to the Matching Period to cease to be a Superior Proposal.

(3) Each successive modification to any Acquisition Proposal that results in an increase to, or a modification of, the amount or form of consideration to be received by Shareholders or other amendment to the material terms or conditions thereof shall constitute a new Acquisition Proposal for purposes of the requirements under Section 5.4, and the Parent shall be afforded a new two (2) Business Day Matching Period from the later of the date on which the Parent received the Superior Proposal Notice and the date on which the Parent received all of the materials set forth in Section 5.4(1)(c) above.

(4) Upon the written request of the Parent, the Board shall promptly reaffirm the Board Recommendation by press release (but, on no more than two (2) occasions) after any Acquisition Proposal which is not determined by the Board to be a Superior Proposal is publicly announced or the Board determines that a proposed revision to the terms of this Agreement as contemplated under Section 5.4(2) would result in an Acquisition Proposal no longer being a Superior Proposal (it being understood that publicly taking no position or a neutral position with respect to an Acquisition Proposal for a period of no more than ten (10) Business Days following the formal announcement of such Acquisition Proposal, including a customary “stop-look-and-listen” or similar communication, shall not be considered to be in violation of this Section 5.4(4) provided the Board has re-affirmed the Board Recommendation before the end of such ten (10) Business Day period). The Corporation shall provide the Parent and its outside legal advisors with a reasonable opportunity to review the form and content of any such press release and shall make all reasonable amendments to such press release as requested by the Parent and its counsel.

(5) If the Corporation provides a Superior Proposal Notice to the Parent after a date that is less than five (5) Business Days before the Meeting, the Corporation may, and shall if directed by the Parent, postpone or adjourn the Meeting to a date that is not more than ten (10) Business Days after the scheduled date of the Meeting, but in any event to a date that is not less than three (3) Business Days prior to the Outside Date.

Section 5.5 Breach by Subsidiaries and Representatives.

Without limiting the generality of the foregoing, the Corporation shall advise its Subsidiaries and its and their respective Representatives of the prohibitions set out in this Article 5 and any violation of the restrictions set forth in this Article 5 by its Subsidiaries or its or their respective Representatives (acting at the direction or on behalf of the Corporation) shall be deemed to be a breach of this Article 5 by the Corporation.

(5) For the purposes of this Agreement, the “Parent Termination Fee Event” means the termination of this Agreement (a) pursuant to Section 7.2(2)(b) [Illegality] (solely if the applicable Law, injunction, judgment, order or decree relates to the matters referenced in Section 6.1(3) (other than the Investment Canada Act Approval)) or (b) pursuant to Section 7.2(2)(c) [Occurrence of Outside Date], in each case if at the time of such termination, all of the conditions set forth in Section 6.1 and Section 6.2 have been satisfied (excluding any conditions that, by their terms, cannot be satisfied until the Effective Date, but subject to the satisfaction or, where not prohibited, waiver of those conditions as of the Effective Date by the applicable Party or Parties for whose benefit such conditions exist), other than the conditions set forth in Section 6.1(3) [Required Regulatory Approvals] (but provided that the Investment Canada Act Approval has been obtained) or Section 6.1(4) [Illegality] (in each case, solely as it relates to the matters referenced in Section 6.1(3) (other than the Investment Canada Act Approval)).

(7) The Parties acknowledge that the agreements contained in this Section 7.3 are an integral part of the transactions contemplated by this Agreement, and that without these agreements the Parties would not enter into this Agreement, and that the amounts set out in this Section 7.3 represent consideration for the disposition of the affected Party’s rights under this Agreement and liquidated damages which are a genuine pre-estimate of the damages, including opportunity costs, reputational damage and out-of-pocket expenditures, which the Parties, as applicable, will suffer or incur as a result of the event giving rise to such damages and resultant termination of this Agreement, and is not a penalty. Each Party irrevocably waives any right it may have to raise as a defence that any such liquidated damages are excessive or punitive.

(8) Subject to the Parties’ rights to injunctive and other non-monetary equitable relief or specific performance in accordance with Section 8.6 to prevent breaches or threatened breaches of this Agreement and to enforce compliance with the terms of this Agreement, each Party hereby expressly acknowledges and agrees that, upon any termination of this Agreement under circumstances where the Parent is entitled to the Corporation Termination Fee and such Corporation Termination Fee is paid in full or the Corporation is entitled to the Parent Termination Fee and such Parent Termination Fee is paid in full, the Party receiving such payment shall be precluded from any other remedy against the other Party at Law or in equity or otherwise (including an order for specific performance), and shall not seek to obtain any recovery, judgment or damages of any kind against the other Party or its Subsidiaries or any of their respective directors, officers, employees, partners, managers, members, shareholders or affiliates or their respective representatives, in connection with this Agreement or the transactions contemplated hereby; provided, however, that this limitation shall not apply in the event of fraud or Wilful breach by the Party making such payment (or any of its Subsidiaries) (which liability therefore shall not be affected by termination of this Agreement or any payment of the Corporation Termination Fee or the Parent Termination Fee, as applicable).

(9) The Corporation shall not be obliged to make more than one Corporation Termination Fee payment pursuant to this Section 7.3. The Parent shall not be obliged to make more than one Parent Termination Fee payment pursuant to this Section 7.3.

(2) Any notice or other communication is deemed to be given and received if sent by personal delivery, same day courier or electronic mail, on the date of delivery if it is a Business Day and the delivery was made prior to 5:00 p.m. (local time in place of receipt) and otherwise on the next Business Day. A Party may change its address for service from time to time by providing a notice in accordance with the foregoing. Any subsequent notice or other communication must be sent to the Party at its changed address. Any element of a Party’s address that is not specifically changed in a notice will be assumed not to be changed. Sending a copy of a notice or other communication to a Party’s outside legal counsel as contemplated above is for information purposes only and does not constitute delivery of the notice or other communication to that Party. The failure to send a copy of a notice or other communication to outside legal counsel does not invalidate delivery of that notice or other communication to a Party.

Section 8.4 Time of the Essence.

Time is of the essence in this Agreement.

Section 8.5 Further Assurances.

Subject to the terms and conditions of this Agreement, the Parties will, from time to time, do all acts and things and execute and deliver, or cause to be executed and delivered, all such further documents and instruments, as the other Parties may, either before or after the Effective Date, reasonably require to effectively carry out or better evidence or perfect the full intent and meaning of this Agreement and, in the event the Arrangement becomes effective, to document or evidence any of the transactions or events set out in the Plan of Arrangement.

Section 8.6 Injunctive Relief.

The Parties agree that irreparable harm would occur for which money damages would not be an adequate remedy at law in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. Subject to Section 7.3(8), it is accordingly agreed that the Parties shall be entitled (without proof of actual damages or otherwise or posting or securing any bond or other security), in addition to any other remedy to which they are entitled to under law or equity, to specific performance of the terms of this Agreement and an injunction or injunctions and other equitable relief to prevent breaches or threatened breaches of this Agreement, and to specifically enforce compliance with the terms of this Agreement. The Corporation, on the one hand, and the Parent and the Purchaser, on the other hand, hereby agree not to raise any objections to the availability of the equitable remedy of specific performance to prevent or restrain breaches or threatened breaches of this Agreement by such Party or Parties. Any Party’s pursuit of any injunction or specific performance at any time shall not be deemed an election of remedies or waiver of the right to pursue any other right or remedy to which such Party may be entitled, including the right to pursue remedies for liabilities or damages incurred or suffered by a Party in the case of a breach of this Agreement involving fraud or Wilful breach.

Section 8.7 Third Party Beneficiaries.

(1) Except (a) for the rights of the Securityholders to receive the applicable Consideration following the Effective Time pursuant to the Plan of Arrangement, and (b) as provided in Section 4.9 [Insurance and Indemnification] (and Section 4.17 [Guarantee of the Parent], solely as it relates to Section 4.9) which, without limiting its terms, is intended for the benefit of the third Persons mentioned in such provisions (such third Persons referred to in this Section 8.7 as the Indemnified Persons), the Parties intend that this Agreement will not benefit or create any right or cause of action in favour of any Person, other than the Parties and that no Person, other than the Parties, shall be entitled to rely on the provisions of this Agreement in any action, suit, proceeding, hearing or other forum.

(2) Despite the foregoing, each of the Parent and the Purchaser acknowledges to each of the Indemnified Persons his or her direct rights against it under Section 4.9 [Insurance and Indemnification] of this Agreement, which are intended for the benefit of, and shall be enforceable by, each Indemnified Person, his or her heirs and his or her legal representatives.

A-57

Section 8.8 Waiver.

No waiver of any of the provisions of this Agreement will constitute a waiver of any other provision (whether or not similar). No waiver will be binding unless executed in writing by the Party to be bound by the waiver. A Party’s failure or delay in exercising any right under this Agreement will not operate as a waiver of that right. A single or partial exercise of any right will not preclude a Party from any other or further exercise of that right or the exercise of any other right.

Section 8.9 Entire Agreement.

This Agreement, including the Schedules hereto, together with the Corporation Disclosure Letter, the CVR Agreement and the Confidentiality Agreement constitutes the entire agreement between the Parties with respect to the transactions contemplated by this Agreement and supersedes all prior agreements, understandings, negotiations and discussions, whether oral or written, of the Parties. There are no representations, warranties, covenants, conditions or other agreements, express or implied, collateral, statutory or otherwise, between the Parties in connection with the subject matter of this Agreement, except as specifically set forth in this Agreement. The Parties have not relied and are not relying on any other information, discussions or understanding in entering into and completing the transactions contemplated by this Agreement.

Section 8.10 Successors and Assigns.

(1) This Agreement becomes effective only when executed by the Corporation, the Parent and the Purchaser. After that time, it will be binding upon and inure to the benefit of the Corporation, the Parent, the Purchaser and their respective successors and permitted assigns.

(2) Neither this Agreement nor any of the rights or obligations under this Agreement are assignable or transferable by any Party without the prior written consent of the other Parties, except that the Parent and/or the Purchaser may assign, in its sole discretion, all or any portion of its rights, interests and obligations under this Agreement to one of its affiliates, but no such assignment shall relieve the assigning party of its obligations hereunder if such assignee does not perform such obligation.

Section 8.11 Severability.

If any provision of this Agreement is determined to be illegal, invalid or unenforceable by an arbitrator or any court of competent jurisdiction, that provision will be severed from this Agreement and the remaining provisions shall remain in full force and effect. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the Parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible in an acceptable manner to the end that the transactions contemplated hereby are fulfilled to the fullest extent possible.

Section 8.12 Governing Law.

This Agreement shall be governed, including as to validity, interpretation and effect, by the Laws of the Province of Ontario and the Laws of Canada applicable therein. Each Party irrevocably attorns and submits to the exclusive jurisdiction of the Ontario courts situated in the City of Toronto and waives objection to the venue of any proceeding in such court or that such court provides an inconvenient forum.

Section 8.13 Rules of Construction.

The Parties to this Agreement waive the application of any Law or rule of construction providing that ambiguities in any agreement or other document shall be construed against the party drafting such agreement or other document.

A-58

Section 8.14 No Liability.

No director or officer of the Parent or the Purchaser, shall have any personal liability whatsoever to the Corporation under this Agreement or any other document delivered in connection with the transactions contemplated hereby on behalf of the Parent or the Purchaser. No director or officer of the Corporation or any of its Subsidiaries shall have any personal liability whatsoever to the other Parties under this Agreement or any other document delivered in connection with the transactions contemplated hereby on behalf of the Corporation or any of its Subsidiaries.

Section 8.15 Counterparts.

This Agreement may be executed in any number of counterparts (including counterparts by executed electronic copy) and all such counterparts taken together shall be deemed to constitute one and the same instrument. The Parties agree that electronic signatures will have the same legal effect as original signatures and that the Parties shall be entitled to rely upon delivery of an executed electronic copy of this Agreement, and such executed electronic copy shall be legally effective to create a valid and binding agreement between the Parties, and that an electronic, scanned, or duplicate copy of any signatures will be deemed an original and may be used as evidence of execution.

CONTINGENT VALUE RIGHTS

Section 2.1 CVRs. The CVRs represent the rights of Holders to receive a contingent cash payment pursuant to the Arrangement Agreement and this Agreement. The initial Holders shall be determined pursuant to the terms of the Arrangement Agreement and this Agreement, and a list of the initial Holders shall be furnished by or on behalf of the Purchaser to the Rights Agent in accordance with Section 4.1 hereof.

Section 2.2 Nontransferable. The CVRs may not be sold, assigned, transferred, pledged, encumbered or in any other manner transferred or disposed of, in whole or in part, other than through a Permitted Transfer. Any attempted sale, assignment, transfer, pledge, encumbrance or disposition of any CVR, in whole or in part, in violation of this Section 2.2 shall be null and void ab initio and of no effect.

Section 2.3 No Certificate; Registration; Registration of Transfer; Change of Address.

(a) The CVRs shall not be evidenced by a certificate or other instrument.

(b) The Rights Agent shall keep a register (the “CVR Register”) for the purpose of (i) identifying the Holders of CVRs and (ii) registering CVRs and Permitted Transfers thereof. In the case of CVRs to be received by the holders of Shares (other than Dissenting Shares), Options, RSUs and Warrants, such CVRs shall initially be registered in the name and address of the holder of such Shares, Options, RSUs and Warrants, as applicable, as set forth in the records of the Corporation at the Effective Time and as set forth in the form the Corporation furnishes to the Rights Agent.

(c) Subject to the restrictions on transferability set forth in Section 2.2, every request made to transfer a CVR must be in writing and accompanied by a written instrument of transfer in form reasonably satisfactory to the Rights Agent pursuant to its guidelines, duly executed by the Holder thereof, the Holder’s attorney duly authorized in writing, the Holder’s personal representative or the Holder’s survivor, and setting forth in reasonable detail the circumstances relating to the proposed transfer. On receipt of such written notice, the Rights Agent shall, subject to its reasonable determination that the transfer instrument is in proper form and the proposed transfer otherwise complies with the other terms and conditions of this Agreement (including the provisions of Section 2.2), register the transfer of the CVRs in the CVR Register. The Purchaser and the Rights

Agent may require payment of a sum sufficient to cover any stamp or other Tax or governmental charge that is imposed in connection with any such registration of transfer. The Rights Agent shall have no duty or obligation to take any action under any Section of this Agreement that requires the payment by a Holder of a CVR of such applicable Taxes or charges unless and until the Rights Agent is satisfied that all such applicable Taxes or charges have been paid. All duly transferred CVRs registered in the CVR Register shall be the valid obligations of the Purchaser and shall entitle the transferee to the same benefits and rights under this Agreement as those held immediately prior to the transfer by the transferor. No transfer of a CVR shall be valid until registered in the CVR Register in accordance with this Agreement.

(d) A Holder (or an authorized representative thereof) may make a written request to the Rights Agent to change such Holder’s address of record in the CVR Register. The written request must be duly executed by the Holder (or an authorized representative thereof). On receipt of such written notice, the Rights Agent shall promptly record the change of address in the CVR Register.

Section 2.4 Payment Procedures.

(a) If the Milestone is achieved on or prior to the Milestone Outside Date, then (i) as soon as reasonably practicable (but in no event later than thirty (30) days) following the date on which the Milestone is achieved, the Purchaser shall deliver to the Rights Agent written notice indicating that the Milestone has been achieved (the “Milestone Notice” and the date on which such Milestone Notice is delivered to the Rights Agent, the “Milestone Notice Date”) and instructing the Rights Agent to solicit tax forms or other information required to make Tax deductions or withholdings as set forth in Section 2.4(d), and (ii) no later than twenty (20) days after the Milestone Notice Date, the Purchaser shall deliver to the Rights Agent cash, by wire transfer of immediately available funds to an account specified by the Rights Agent, equal to the aggregate amount necessary to pay the Milestone Payment Amounts to all Holders pursuant to Section 2.4(b) other than Milestone Payment Amounts with respect to Employee Equity Awards and Non-Employee Awards (with respect to which any such amounts payable shall be retained by the Purchaser for payment pursuant to Section 2.4(b)) (the total cash deposited with the Rights Agent, the “Payment Fund”).

(b) The Rights Agent shall promptly, and in any event within ten (10) Business Days after receipt of the Payment Fund, send each Holder at its registered address a copy of the Milestone Notice and pay the applicable Milestone Payment Amount (other than Milestone Payment Amounts that are payable with respect to Employee Equity Awards and Non-Employee Awards) to each of the Holders (i) by check mailed to the address of each such respective Holder as reflected in the CVR Register as of the close of business on the last Business Day before the Milestone Payment is made or (ii) with respect to any Holder who has provided the Rights Agent with wire transfer instructions meeting the Rights Agent’s requirements, by wire transfer of immediately available funds to such account. As soon as reasonably practicable after the Milestone Notice Date (but no later than the first payroll date that is not less than ten (10) Business Days after the Milestone Notice Date), the Purchaser shall, or shall cause the Corporation or an Affiliate of the Corporation to, (A) with respect to Milestone Payment Amounts that are payable with respect to Employee Equity Awards, pay through the Corporation’s or the applicable Affiliate’s payroll the aggregate Milestone Payment Amount payable to the applicable holders with respect to such Employee Equity Awards (net of any withholding Taxes required to be deducted and withheld by applicable Tax law in accordance with the Arrangement Agreement or Section 2.4(d)) and (B) with respect to Milestone Payment Amounts that are payable with respect to Non-Employee Awards, pay through the Corporation’s or the applicable Affiliate’s accounts payable or other general account (other than the payroll account) the aggregate Milestone Payment Amount payable to the applicable holders with respect to such Non-Employee Awards (net of any withholding Taxes required to be deducted and withheld by applicable Tax law in accordance with the Arrangement Agreement or Section 2.4(d)). Notwithstanding anything in this Agreement to the contrary, it is the intent of the parties that the Milestone shall be deemed to constitute a substantial risk of forfeiture within the meaning of Section 409A of the Code.

(c) Except to the extent any portion of the Milestone Payment Amounts are required to be treated as imputed interest pursuant to applicable Tax law, the Holders and the parties hereto (i) for U.S. federal and applicable state and local income Tax purposes, agree to treat the CVRs (other than CVRs received in respect of

Employee Equity Awards and Non-Employee Awards and Canadian Options) and the Milestone Payment Amounts of such CVRs as additional consideration for the Shares (other than Dissenting Shares) pursuant to the Arrangement Agreement; (ii) agree to treat the CVRs received in respect of Employee Equity Awards and Non-Employee Awards and the Milestone Payment Amounts of such CVRs, and not the receipt of any such CVR, for all U.S. federal and applicable state and local income Tax purposes, as compensation (subject to withholding Taxes to the extent required by applicable law) in the year in which such Milestone Payment is made; and (iii) intend to treat the CVRs received by a Canadian Optionholder for Canadian Tax purposes as additional consideration for the disposition of the Canadian Options pursuant to the Arrangement Agreement and Plan of Arrangement and treat the Milestone Payment Amounts as proceeds of disposition with respect to such CVRs (provided that treatment not otherwise described in (i), (ii) and (iii) shall be determined by the Purchaser in its good faith discretion following consultation with a reputable international tax accounting firm, provided that such treatment shall not be inconsistent with the terms of the Arrangement Agreement and applicable Tax law), and none of the Holders and the parties hereto shall take any position to the contrary on any Tax Return or for other Tax purposes except as required by applicable Tax law. The Purchaser and the Corporation shall, to the extent required for U.S. federal and applicable state and local income Tax purposes, report imputed interest on the CVRs (other than CVRs received in respect of Employee Equity Awards and Non-Employee Awards) pursuant to Section 483 of the Code.

(d) Each of the Corporation (and any applicable Affiliate), the Purchaser, the Purchaser and Rights Agent shall be entitled to deduct and withhold from any cash amounts payable pursuant to this Agreement such amounts as it is required to deduct and withhold by any applicable Tax law. With respect to a holder of an Employee Equity Award, any deduction or withholding may be made, or caused to be made, by the Purchaser through the Purchaser’s, the Corporation’s or its applicable Affiliate’s payroll system. Prior to making any such Tax deductions or withholdings or causing any such Tax deductions or withholdings to be made with respect to any Holder (other than a Holder in such Holder’s capacity as a holder of an Employee Equity Award), the Purchaser shall instruct the Rights Agent to solicit Internal Revenue Service (“IRS”) Form W-9s or W-8s, or any other appropriate forms or information, from Holders within a reasonable amount of time in order to provide a reasonable opportunity for the Holder to timely provide any necessary Tax forms (including an IRS Form W-9 or an applicable IRS Form W-8) in order to avoid or reduce such withholding, and the Milestone Payment Amount may be reasonably delayed in order to gather such necessary Tax forms. The Purchaser, the Corporation, any applicable Affiliate and the Rights Agent may assume all such forms in its possession or provided by any Holder are valid under applicable Tax law until subsequently notified by such Holder. To the extent that amounts are so withheld and remitted to the appropriate Governmental Entity, such amounts so remitted shall be treated for all purposes under this Agreement as having been paid to the Person to whom such amounts would otherwise have been paid. The Purchaser shall deliver (or shall cause the Rights Agent, the Corporation or its applicable Affiliate to deliver) to the Person to whom such amounts would otherwise have been paid an original IRS Form 1099 (or in the case of payments to a holder of an Employee Equity Award, an original IRS Form W-2, if applicable) or other reasonably acceptable evidence of such deduction or withholding.

(e) Any portion of any Milestone Payment Amount that remains undistributed to a Holder 12 months after the date of the Milestone Notice Date shall be delivered by the Rights Agent to the Corporation on demand by the Purchaser, and any Holder shall be entitled to look to the Corporation (subject to abandoned property, escheat and other similar applicable law) only as general creditors thereof with respect to the Milestone Payment Amount payable hereunder, without any interest thereon. None of the Purchaser, the Corporation or the Rights Agent shall be liable to any Holder for any such consideration delivered in respect of a CVR to a public official pursuant to any abandoned property, escheat or other similar applicable law. Any amounts remaining unclaimed by such holders at such time at which such amounts would otherwise escheat to or become property of any Governmental Entity shall become, to the extent permitted by applicable law, the property of the Corporation or its designee, free and clear of all claims or interest of any Person previously entitled thereto.

(f) The Payment Fund shall not be used for any purpose other than the payment of the Milestone Payment Amounts; provided that any interest or income produced by investments with respect to the Payment Fund shall be the property of the Purchaser. The Payment Fund may be invested by the Rights Agent as directed by the Purchaser; provided that such investments shall be (i) in obligations of, or guaranteed by, the United States

of America, (ii) in commercial paper obligations rated A-1 or P-1 or better by Moody’s Investors Service, Inc. or Standard & Poor’s Corporation, respectively, (iii) in certificates of deposit, bank repurchase agreements or banker’s acceptances of commercial banks with capital exceeding $1 billion, or (iv) in money market funds having a rating in the highest investment category granted by a recognized credit rating agency at the time of acquisition or a combination of the foregoing, and, in any such case, no such investment shall (A) relieve the Purchaser or the Rights Agent from making the payment required by this Section 2.4 or (B) have maturities that could prevent or delay payments to be made pursuant to this Agreement. To the extent that the Payment Fund diminishes for any reason below the level required to make prompt payment of the aggregate Milestone Payment Amounts, the Purchaser shall promptly replace or restore, or cause to be replaced or restored, the lost portion of such fund so as to ensure that it is, at all times, maintained at a level sufficient to make the Milestone Payment Amounts; provided that in no event shall this sentence require the Purchaser to deliver any funds to the Rights Agent prior to the time specified in Section 2.4(a).

(g) For the avoidance of doubt, the Milestone Payment Amount shall only be paid in respect of the Milestone, if at all, one time under this Agreement and the Milestone Payment Amount shall not become payable unless the Milestone has been achieved on or prior to the Milestone Outside Date.

Section 2.5 No Voting, Dividends or Interest; No Equity or Ownership Interest in the Purchaser.

(a) The CVRs shall not have any voting or dividend rights, and interest shall not accrue on any amounts payable on the CVRs to any Holder.

(b) The CVRs shall not represent any equity or ownership interest in the Purchaser, any constituent company to the Arrangement or any of their respective Affiliates.

Section 2.6 Ability to Abandon CVR. A Holder may at any time, at such Holder’s option, abandon all of such Holder’s remaining rights in a CVR by transferring such CVR to the Purchaser or any of its Affiliates without consideration therefor, which abandonment a Holder may effect by delivery of a written notice of such transfer and abandonment to the Purchaser. Nothing in this Agreement shall prohibit the Purchaser or any of its Affiliates from offering to acquire or acquiring any CVRs for consideration from the Holders, in private transactions or otherwise, in its sole discretion. Any CVRs acquired by the Purchaser or any of its Affiliates shall be automatically deemed extinguished and no longer outstanding, including for purposes of the definition of Acting Holders and ARTICLE 5 and Section 6.3.

A Party may change its address for service from time to time by providing a notice in accordance with the foregoing. Any subsequent notice or other communication must be sent to the Party at its changed address. Any element of a Party’s address that is not specifically changed in a notice will be assumed not to be changed. Sending a copy of a notice or other communication to a Party’s outside legal counsel as contemplated above is for information purposes only and does not constitute delivery of the notice or other communication to that Party. The failure to send a copy of a notice or other communication to outside legal counsel does not invalidate delivery of that notice or other communication to a Party.

Section 6.2 Notice to Holders. Where this Agreement provides for notice to Holders, such notice shall be sufficiently given (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to each Holder affected by such event, at the Holder’s address as it appears in the CVR Register, not later than the latest date, and not earlier than the earliest date, if any, prescribed for the giving of such notice. In any case where notice to Holders is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders.

Section 6.3 Successors and Assigns. Parent and the Purchaser may assign any or all of its rights, interests and obligations hereunder to (a) in its sole discretion and without the consent of any other party, subject to Section 4.3(c)(ii), any Affiliate of Parent, but only for so long as it remains an Affiliate of Parent, or (b) with the prior written consent of the Acting Holders, any other Person (provided that no such consent shall be required in connection with this Section 6.3(b) for assignments complying with Section 4.3(c)) (any permitted assignee under clause (a) or (b), an “Assignee”), in each case, provided that the Assignee agrees in a writing reasonably acceptable to the Rights Agent that is delivered to the Rights Agent to assume and be bound by all of the terms of this Agreement. Any Assignee may thereafter assign any or all of its rights, interests and obligations hereunder in the same manner as Parent and the Purchaser pursuant to the prior sentence. Solely in connection with any assignment to an Assignee described in clause (a) above in this Section 6.3, Parent and the Purchaser (or the other applicable assignor) shall agree to remain liable for the performance by each Assignee (and such other assignor, if applicable) of all obligations of Parent and the Purchaser hereunder, with such Assignee substituted for Parent and the Purchaser under this Agreement. This Agreement shall be binding on, and shall be enforceable by and inure solely to the benefit of, Parent’s and the Purchaser’s successors and each Assignee. Each of Parent’s and the Purchaser’s successors and Assignees shall expressly assume by an instrument supplemental hereto, executed and delivered to the Rights Agent, the due and punctual payment of all Milestone Payment Amounts and the due and punctual performance and observance of all of the covenants and obligations of this Agreement to be performed or observed by Parent or the Purchaser. The Rights Agent may not assign this Agreement without Parent’s and the Purchaser’s prior written consent. Any attempted assignment of this Agreement or any such rights in violation of this Section 6.3 shall be void and of no effect.

Section 6.4 Benefits of Agreement. Nothing in this Agreement, express or implied, is intended to or shall confer on any Person (other than the Rights Agent, Parent, the Purchaser, the respective successors and Assignees of Parent and the Purchaser, the Holders and the Holders’ successors and assigns pursuant to a Permitted Transfer) any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement. The rights of Holders and their successors and assigns pursuant to Permitted Transfers are limited to those expressly provided in this Agreement and the Arrangement Agreement. Notwithstanding anything to the contrary

contained herein, any Holder or Holder’s successor or assign pursuant to a Permitted Transfer may agree to renounce, in whole or in part, its rights under this Agreement by written notice to the Rights Agent, Parent and the Purchaser, which notice, if given, shall be irrevocable. Except for the rights of the Rights Agent expressly set forth herein, the Acting Holders shall have the sole right, on behalf of all Holders, by virtue of or under any provision of this Agreement, to institute any action or proceeding with respect to this Agreement, and no individual Holder or other group of Holders shall be entitled to exercise such rights. Reasonable expenditures incurred by such Acting Holders in connection with any enforcement action hereunder may be deducted from any damages or settlement obtained prior to the distribution of any remainder to Holders generally. The Acting Holders acting pursuant to this Section 6.4 on behalf of all Holders shall have no liability to any other Holders for such actions.

Section 6.5 Applicable Laws; Jurisdiction.

(a) This Agreement and the CVRs shall be interpreted, construed and governed by and in accordance with the laws of the State of Delaware without regard to the conflicts of law principles thereof that would subject such matter to the laws of another jurisdiction. Each of the parties hereto irrevocably and unconditionally agrees that any legal action or proceeding with respect to this Agreement, the CVRs and the rights and obligations arising hereunder, or for recognition and enforcement of any judgment in respect of this Agreement, the CVRs and the rights and obligations arising hereunder brought by the another party or its successors or assigns, shall be brought and determined exclusively in the Delaware Court of Chancery and any state appellate court therefrom within the State of Delaware (or, solely if the Delaware Court of Chancery declines to accept jurisdiction over a particular matter, any state or federal court within the State of Delaware). Each of the parties hereto hereby irrevocably and unconditionally submits with regard to any such action or proceeding for itself and in respect of its property to the personal jurisdiction of the aforesaid courts and agrees that it shall not bring any action relating to this Agreement or the CVRs in any court other than the aforesaid courts. Each of the parties hereto hereby irrevocably waives, and agrees not to assert, by way of motion, as a defense, counterclaim or otherwise, in any action or proceeding with respect to this Agreement or the CVRs, (i) any claim that it is not personally subject to the jurisdiction of the above named courts, (ii) any claim that it or its property is exempt or immune from jurisdiction of any such court or from any legal process commenced in such courts (whether through service of notice, attachment prior to judgment, attachment in aid of execution of judgment, execution of judgment or otherwise) and (iii) to the fullest extent permitted by applicable law, any claim that (i) the suit, action or proceeding in such court is brought in an inconvenient forum, (ii) the venue of such suit, action or proceeding is improper or (iii) this Agreement, or the subject matter hereof, may not be enforced in or by such courts. To the fullest extent permitted by applicable law, each of the parties hereto hereby consents to the service of process in accordance with Section 6.1 and Section 6.2; provided that nothing herein shall affect the right of any party to serve legal process in any other manner permitted by applicable law.

(b) EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER OR RELATING TO THIS AGREEMENT OR THE CVRS IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH SUCH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT, THE CVRS OR THE OTHER TRANSACTIONS CONTEMPLATED HEREBY. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT (I) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER, (II) EACH PARTY UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (III) EACH PARTY MAKES THIS WAIVER VOLUNTARILY, AND (IV) EACH PARTY HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 6.5(B).

Section 6.6 Severability. If any provision of this Agreement is determined to be illegal, invalid or unenforceable by an arbitrator or any court of competent jurisdiction, that provision will be severed from this Agreement and the remaining provisions shall remain in full force and effect. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the Parties shall negotiate in good faith

to modify this Agreement so as to effect the original intent of the Parties as closely as possible in an acceptable manner to the end that the transactions contemplated hereby are fulfilled to the fullest extent possible.

Section 6.7 Entire Agreement; Counterparts. This Agreement, the Arrangement Agreement, including the Schedules thereto, together with the Corporation Disclosure Letter, and the Confidentiality Agreement constitute the entire agreement between the Parties with respect to the transactions contemplated by this Agreement and supersedes all prior agreements, understandings, negotiations and discussions, whether oral or written, of the Parties. There are no representations, warranties, covenants, conditions or other agreements, express or implied, collateral, statutory or otherwise, between the Parties in connection with the subject matter of this Agreement, except as specifically set forth in this Agreement. The Parties have not relied and are not relying on any other information, discussions or understanding in entering into and completing the transactions contemplated by this Agreement. This Agreement may be executed in any number of counterparts (including counterparts by executed electronic copy) and all such counterparts taken together shall be deemed to constitute one and the same instrument. The Parties agree that electronic signatures will have the same legal effect as original signatures and that the Parties shall be entitled to rely upon delivery of an executed electronic copy of this Agreement, and such executed electronic copy shall be legally effective to create a valid and binding agreement between the Parties, and that an electronic, scanned, or duplicate copy of any signatures will be deemed an original and may be used as evidence of execution.

Section 6.8 Termination. This Agreement shall be terminated and be of no force or effect, the parties hereto shall have no liability hereunder (other than with respect to monies due and owing by the Purchaser to Rights Agent), and no payments shall be required to be made, on the earlier to occur of (a) the mailing by the Rights Agent to the address of each Holder as reflected in the CVR Register (or payment by wire transfer, as applicable) the full amount of all Milestone Payment Amounts required to be paid under the terms of this Agreement, (b) the delivery of a written notice of termination duly executed by Parent and the Purchaser and the Acting Holders and (c) if the Milestone has not been achieved on or prior to the Milestone Outside Date, one day following the Milestone Outside Date; provided that this Section 6.8 and Section 6.10 shall each survive the termination of this Agreement and shall remain in full force and effect in accordance with their respective terms. Notwithstanding anything in this Agreement to the contrary, no termination of this Agreement shall relieve any party hereto of any liability for any breach of this Agreement occurring prior to such termination.

Section 6.9 Payments on Next Business Day. In the event that any payment in respect of the CVRs shall be required to be made hereunder shall not be a Business Day, then, notwithstanding anything in this Agreement to the contrary, any payment required to be made in respect of the CVRs on such date need not be made on such date, but may be made on the next Business Day thereafter with the same force and effect as if made on the applicable required date.

Section 6.10 Confidentiality. The Rights Agent agrees that all books, records, information and data pertaining to the business of the Purchaser or its Affiliates, including inter alia, personal, non-public Holder information, which are exchanged or received pursuant to the negotiation or the carrying out of this Agreement shall not be used by the Rights Agent for any purpose other than carrying out its duties under this Agreement and shall not be voluntarily disclosed by the Rights Agent to any other Person, including any Holder, except as may be required by a valid order of any Governmental Entity of competent jurisdiction or is otherwise required by applicable law, the rules and regulations of the Securities and Exchange Commission or any stock exchange on which the securities of the Rights Agent are listed, or pursuant to subpoenas from state or federal Governmental Entity (subject to (a) the Rights Agent notifying, to the extent practicable, Parent and the Purchaser of such potential disclosure reasonably in advance of such disclosure (other than disclosure by Rights Agent for stockholder records pursuant to standard subpoenas from state or federal government authorities (e.g., divorce and criminal actions)), (b) cooperating with Parent and the Purchaser, at Parent’s expense, in any effort to restrict disclosure of such books, records, information or data and (c) the Rights Agent only disclosing such books, records, information or data that is required to be so disclosed by such valid order, such applicable law, rule or regulation of the Securities and Exchange Commission, any Canadian securities regulatory authority or any stock exchange on which the securities of the Rights Agent are listed or such subpoena).

15.

20. THIS COURT ORDERS that votes shall be taken at the Meeting on the basis of one vote per Share held. In order for the Plan of Arrangement to be implemented, subject to further Order of this Court, the Arrangement Resolution must be passed, with or without variation, at the Meeting by:

an affirmative vote of at least two-thirds (66²/3%) of the votes cast in respect of the Arrangement Resolution at the Meeting in person or by proxy by the Shareholders; and

(ii)

an affirmative vote of a majority of the votes cast by the Shareholders present in person or represented by proxy at the Meeting, after excluding the votes of those Persons whose votes are required to be excluded under MI 61-101 Protection of Minority Security Holders in Special Transactions.

Such votes shall be sufficient to authorize Fusion to do all such acts and things as may be necessary or desirable to give effect to the Arrangement and the Plan of Arrangement on a basis consistent with what is provided for in the Circular without the necessity of any further approval by the Shareholders, subject only to final approval of the Arrangement by this Court.

21. THIS COURT ORDERS that in respect of matters properly brought before the Meeting pertaining to items of business affecting Fusion (other than in respect of the Arrangement Resolution), each Shareholder is entitled to one vote for each Share held.

Dissent Rights

22. THIS COURT ORDERS that each registered Shareholder shall be entitled to exercise Dissent Rights in connection with the Arrangement Resolution in accordance with section 190 of the CBCA (except as the procedures of that section are varied by this Interim Order and the Plan of Arrangement) provided that, notwithstanding subsection 190(5) of the CBCA, any Shareholder who wishes to dissent must, as a condition precedent thereto, provide written objection to the Arrangement Resolution to Fusion in the form required by section 190 of the CBCA and the Arrangement Agreement, which written objection must be received by Fusion not later than 5:00 p.m. (Eastern time) on the last business day that is two (2) business days immediately preceding the Meeting (or any adjournment or postponement thereof), and must otherwise strictly comply with the requirements of the CBCA. For purposes of these proceedings, the “court” referred to in section 190 of the CBCA means this Court.

23. THIS COURT ORDERS that, notwithstanding section 190(3) of the CBCA, the Purchaser, not Fusion, shall be required to offer to pay fair value, as of the day prior to approval of the Arrangement Resolution, for Shares held by Shareholders who duly exercise Dissent Rights, and to pay the amount to which such Shareholders may be entitled pursuant to the terms of the Arrangement Agreement. Notwithstanding section 190(4) of the CBCA, a registered Shareholder may only exercise Dissent Rights if Dissent Rights are exercised in respect of all Shares registered in the name of such registered Shareholder. In accordance with the Plan of Arrangement and the Circular, all references to the “corporation” in subsections 190(3) and 190(11) to 190(26), inclusive, of the CBCA (except for the second reference to the “corporation” in subsection 190(12) and the two references to the “corporation” in subsection 190(17)) shall be deemed to refer to “the Purchaser” in place of the “corporation”, and the Purchaser shall have all of the rights, duties and obligations of the “corporation” under subsections 190(11) to 190(26), inclusive, of the CBCA.

24. THIS COURT ORDERS that any Shareholder who duly exercises such Dissent Rights set out in paragraph 22 above and who:

is ultimately determined by this Court to be entitled to be paid fair value for his, her or its Shares, shall be deemed to have transferred those Shares as of the time set out in the Plan of Arrangement, without any further act or formality and free and clear of all liens, claims, encumbrances, charges, adverse

ii)

is for any reason ultimately determined by this Court not to be entitled to be paid fair value for his, her or its Shares pursuant to the exercise of the Dissent Right, shall be deemed to have participated in the Arrangement on the same basis and at the same time as any non-dissenting Shareholder;

but in no case shall Fusion, the Purchaser or any other person be required to recognize such Shareholders as of Shares of Fusion at or after the date upon which the Arrangement becomes effective and the names of such Shareholders shall be deleted from Fusion’s register of Shareholders at that time.

Hearing of Application for Approval of the Arrangement

25. THIS COURT ORDERS that upon approval by the Shareholders of the Plan of Arrangement in the manner set forth in this Interim Order, Fusion may apply to this Court for final approval of the Arrangement.

The Board of Directors:

You have requested our opinion as to the fairness, from a financial point of view, to the holders of the outstanding common shares (the “Shares”) (other than Excluded Shares, as defined below), of Fusion Pharmaceuticals Inc., a corporation formed under the federal laws of Canada (the “Company”), of the Consideration (as defined below) proposed to be paid to such holders pursuant to the Arrangement Agreement proposed to be entered into on March 18, 2024 (the “Agreement”) by and among AstraZeneca AB, a public company with limited liability (Aktiebolag) incorporated under the laws of Sweden (“Parent”), 15863210 Canada Inc., a corporation formed under the federal laws of Canada (“Purchaser”), and the Company. The Agreement provides that, among other things, Purchaser will acquire all of the issued and outstanding Shares of the Company by way of a plan of arrangement made pursuant to Section 192 of the Canada Business Corporations Act (the “Arrangement” and, collectively with the other transactions contemplated by the Agreement, the “Transaction”), as a result of which at the effective time of the Arrangement the holders of Shares will be entitled to receive, for each Share (other than (i) any Shares held by Parent or any of its affiliates immediately prior to the Effective Time and (ii) any Shares held by a Dissenting Shareholder (as defined in the Agreement) that is ultimately entitled to be paid fair value by Purchaser for its Shares (the shares referred to in clauses (i) and (ii), “Excluded Shares”)) held by such holders (i) an amount in cash equal to $21.00 per Share (the “Cash Consideration”) plus (ii) one contractual contingent value right (a “CVR”) representing the right to receive a contingent payment in cash equal to $3.00 per Share, subject to applicable withholding, without interest, upon the achievement of the Milestone (as such term is defined in the CVR Agreement in the form attached to the Agreement (the “CVR Agreement”)), in accordance with the terms and conditions of the CVR Agreement (the Cash Consideration taken together (and not separately) with one CVR, the “Consideration”). The terms and conditions of the Transaction are more fully set forth in the Agreement. All dollar amounts herein are expressed in United States dollars unless stated otherwise.

We have acted as financial advisor to the Board of Directors of the Company in connection with the Transaction. We will receive a fee for our services in connection with the Transaction, a portion of which is payable upon the rendering of this opinion and a substantial portion of which is contingent upon the consummation of the Transaction. In addition, the Company has agreed to reimburse certain of our expenses arising, and indemnify us against certain liabilities that may arise, out of our engagement.

We are a securities firm engaged directly and through affiliates and related persons in a number of investment banking, financial advisory and merchant banking activities. In the past two years, except for our

current engagement, we have not been engaged to provide financial advisory or other services to the Company, and we have not received any compensation from the Company during such period. In the past two years, we have not been engaged to provide financial advisory or other services to Parent, and we have not received any compensation from Parent during such period. We may provide financial advisory and other services to or with respect to the Company or Parent or their respective affiliates in the future, for which we may receive compensation. Certain (i) of our and our affiliates’ directors, officers, members and employees, or family members of such persons, (ii) of our affiliates or related investment funds and (iii) investment funds or other persons in which any of the foregoing may have financial interests or with which they may co-invest, may at any time acquire, hold, sell or trade, in debt, equity and other securities or financial instruments (including derivatives, bank loans or other obligations) of, or investments in, the Company, Parent, or any of their respective affiliates, or any other party that may be involved in the Transaction.

In connection with this opinion, we have reviewed, among other things: (i) a draft of the Agreement and a draft of the form of CVR Agreement attached to the Agreement each dated March 18, 2024 (collectively, the “Draft Agreements”); (ii) Annual Reports on Form 10-K of the Company for the years ended December 31, 2022, December 31, 2021, and December 31, 2020; (iii) certain interim reports to shareholders and Quarterly Reports on Form 10-Q of the Company; (iv) certain publicly available research analyst reports for the Company; (v) certain other communications from the Company to its shareholders; and (vi) certain internal information relating to the business, operations, earnings, cash flow, assets, liabilities and prospects of the Company, including certain financial forecasts, analyses and projections relating to the Company, including the probability of realizing the Milestone under the CVR Agreement, prepared by management of the Company and furnished to us by the Company for purposes of our analysis (the “Forecasts”) (collectively, the “Internal Data”). We have also participated in discussions with members of senior management and representatives of the Company regarding their assessment of the Internal Data, and conducted such financial studies and analyses and took into account such other information as we deemed appropriate.

We have assumed, without independent verification or any responsibility therefor, the accuracy and completeness of the financial, legal, regulatory, tax, accounting and other information supplied to, discussed with, or reviewed by us for purposes of this opinion and have, with your consent, relied upon such information as being complete and accurate.

(a) withdraw their notice of dissent, in which case the corporation is deemed to consent to the withdrawal and the shareholder is reinstated to their full rights as a shareholder; or

(b) retain a status as a claimant against the corporation, to be paid as soon as the corporation is lawfully able to do so or, in a liquidation, to be ranked subordinate to the rights of creditors of the corporation but in priority to its shareholders.
