Combination Collaboration Overview.

Overview. The Combination Collaboration will be divided into the following three types of activity: (i) selection of molecular targets to be the subject of the Combination Collaboration (“Combination Target Selection”) as set forth in Section 2.2 through Section 2.3, (ii) evaluation of the selected molecular targets through initial pre-clinical and clinical trials of combinations of Fusion and AstraZeneca compounds (“Combination Research”) as set forth in Section 2.4 through Section 2.5 and (if applicable) Section 2.7 and (iii) further clinical development and (if possible) commercialization of combinations of Fusion and AstraZeneca compounds modulating those molecular targets selected by AstraZeneca to be the subject of such further development (“Combination Development”) as set forth in ARTICLE 6. All activities to be conducted by the Parties during Combination Target Selection and Combination Research will be set forth in the Combination Collaboration Plan. ARTICLE 6 sets forth the allocation or actives to be conducted by the Parties during Combination Development.

Combination Collaboration Plan. All activities to be conducted by the Parties during Combination Target Selection and Combination Research and will be set forth in a plan prepared by the JRC (the “Combination Collaboration Plan”) and approved by the JSC. The Combination Collaboration Plan shall also include a reasonably detailed budget of the costs and expenses for the activities to be conducted pursuant to such plan

Funding. All activities and studies (including FTE Costs) conducted under the Combination Collaboration Plan which are incorporated into the Combination Collaboration Budget will be funded by AstraZeneca.

Target Nomination.

During the period beginning at the Effective Date and ending on the [***] anniversary thereof (the “Nomination Period”), AstraZeneca may nominate any of the molecular targets identified in Appendix 1 (collectively, as may be updated pursuant to Section 2.2.4, the “Combination Collaboration Target Pool”) to be the subject of pre-clinical studies carried out in accordance with Section 2.3 by providing written notice to Fusion of such nomination (a “Nomination Notice”). AstraZeneca may deliver the first Nomination Notice at any time within [***] after the Effective Date, and thereafter each additional Nomination Notice shall be delivered at least [***] prior to each anniversary of the Effective Date. Unless the Parties agree otherwise, until five (5) Combination Collaboration Targets have been nominated, AstraZeneca shall nominate at least [***] and not more than [***] molecular targets in each of the [***] comprising the Nomination Period; provided, that such obligation for AstraZeneca to nominate at least [***] Combination Collaboration Target shall not apply in the event a Phase 1 Study of FPI1434 identifies toxicities making it unsuited for combination with compounds in the AstraZeneca Pipeline.

AstraZeneca shall be permitted to nominate up to, but not more than, five (5) Combination Collaboration Targets pursuant to Section 2.2.1.

For the avoidance of doubt, AstraZeneca shall be permitted to list a specific combination of [***] molecular targets as a target in the Combination Collaboration Target Pool however, if nominated as a combination, each of the constituent molecular targets in the combination will not be reserved as individual targets in the Combination Collaboration Target Pool unless AstraZeneca elects to also separately nominate the constituent molecular targets as targets in the Combination Collaboration Target Pool.

Replacement Target Pool Compounds. Upon providing written notice to Fusion (a “Replacement Notice”), AstraZeneca may replace any molecular target in the Combination Collaboration Target Pool (the “Replaced Target”) with another molecular target (the “Replacing Target”) so long as such target is not a Restricted Target and has not been designated a Combination Collaboration Target. Promptly after receipt of a Replacement Notice, Fusion shall confirm to AstraZeneca in writing whether the Replacing Target is or is not a Restricted Target. Upon confirmation that a Replacing Target is not a Restricted Target, then the Replacing Target will replace the Replaced Target Parties in the Combination Collaboration Target Pool, the Parties shall update Appendix 1 accordingly, and the Replaced Target will become a Restricted Target.

Pre-Clinical Validation

Validation Plan. Promptly after Fusion’s receipt of a Nomination Notice for a given Combination Collaboration Target, the Parties (through the JRC) will prepare and submit to the JSC for approval a plan (each a “Combination Collaboration Validation Plan”) for the conduct of pre-clinical studies by Fusion that are sufficient in scope to enable AstraZeneca, upon receipt of a data package indicating the results of such studies prepared by Fusion in accordance with parameters set forth in the applicable Combination Collaboration Validation Plan (each a “Combination Collaboration Pre-Clinical Data Package”), to make an informed decision on the viability of further studying the combination of a compound in the AstraZeneca Pipeline modulating such Combination Collaboration Target with FPI1434 (or, if mutually agreed by the Parties, another compound in the Fusion Pipeline). Upon approval by the JSC, the JSC will amend the Combination Collaboration Plan to incorporate such Combination Collaboration Validation Plan and Fusion will use its Commercially Reasonable Efforts to undertake such agreed pre-clinical activities and generate the Combination Collaboration Pre-Clinical Data Package in accordance with the timelines and budget set forth in the applicable Combination Collaboration Validation Plan.

Delivery of Data Package. Promptly upon completion thereof, Fusion shall submit each Combination Collaboration Pre-Clinical Data Package to the JRC for review and confirmation. If the JRC makes a determination that such Combination Collaboration Pre-Clinical Data Package does not conform to the requirements in the applicable Combination Collaboration Validation Plan, the JRC shall identify such non-conformities and (i) the Parties (through the JRC) will submit an amendment to the applicable Combination Collaboration Validation Plan (including the applicable Combination Collaboration Budget) for further work to be conducted by Fusion to correct such non-conformities and (ii) Fusion will re-commence Research activities in accordance with such amended Combination Collaboration Validation Plan and re-submit a Combination Collaboration Pre-Clinical Data Package to the JRC in accordance with the terms of this Section 2.3.2 upon completion thereof. For avoidance of doubt, AstraZeneca will reimburse Fusion in accordance with Section 7.4.1(i) for all costs incurred by Fusion under any Combination Collaboration Plan amended in accordance with this Section 2.3.2.

In the event that AstraZeneca reasonably determines that one or more additional pre-clinical studies are required in order to establish the safety and/or dosing of a given combination of FPI1434 (or, if mutually agreed by the Parties, another compound in the Fusion Pipeline) and a compound in the AstraZeneca Pipeline modulating a Combination Collaboration Target, AstraZeneca may notify Fusion that it wishes to undertake and fund such studies and the Parties will work jointly (through the JRC) to prepare and submit to the JSC for approval an amendment to the Combination Collaboration Plan (including the applicable Combination Collaboration Budget) to incorporate such studies. The Parties hereby agree that the Validation Trial Decision Period will be suspended for a period not to exceed [***] during the execution of any such additional studies. For avoidance of doubt, AstraZeneca will reimburse Fusion in accordance with Section 7.4.1(i) for all costs incurred by Fusion under any Combination Collaboration Plan amended in accordance with this Section 2.3.3.

Combination Target Validation Trials

Upon delivery of a written notice to Fusion (“Combination Target Validation Trial Notice”) and payment of the Specific Combination Evaluation Exclusivity Fee, at any time during the Validation Trial Decision Period, AstraZeneca, in its sole discretion, may elect to sponsor a clinical trial (each a “Combination Target Validation Trial”) during the Evaluation Period combining a compound in the AstraZeneca Pipeline modulating the applicable Combination Collaboration Target with FPI1434 (or, if mutually agreed by the Parties, another compound in the Fusion Pipeline); provided that, AstraZeneca shall not be required to pay a Specific Combination Evaluation Exclusivity Fee to exercise such election in the event such fee has then been paid with respect to the applicable Combination Collaboration Target pursuant to Section 2.7.2.

Promptly upon AstraZeneca’s delivery of a Combination Target Validation Trial Notice, the Parties will meet to discuss and generate plans for the activities to be conducted during the applicable Combination Target Validation Trial it being understood and agreed that, except for the supply of materials set forth in Section 2.8.1, AstraZeneca will sponsor and operationally run each Combination Target Validation Trial. Upon completion of such planning, the Parties shall prepare (through the JRC) and submit a proposed amendment to the Combination Collaboration Plan (and Combination Collaboration Budget) to the JSC for its review and approval.

Upon receipt of JSC approval of an amendment to the Combination Collaboration Plan submitted pursuant to Section 2.4.2, AstraZeneca will use its Commercially Reasonable Efforts to advance each Combination Target Validation Trial in accordance with the Combination Collaboration Plan, including the timelines set forth therein.

During the Evaluation Period, unless otherwise agreed between the Parties, AstraZeneca may only elect to sponsor [***] for each Combination Collaboration Target. For the avoidance of doubt, this limitation does not apply to Subsequent Radioconjugate Validation Trials.

Exclusive Combination Targets. On a Combination Collaboration Target by Combination Collaboration Target basis, in the event AstraZeneca enrolls its first patient in a Combination Target Validation Trial within [***] of the date Fusion received the applicable Combination Target Validation Trial Notice, then AstraZeneca, at any time thereafter prior to the expiry of the Evaluation Period for such Combination Collaboration Target, shall be entitled to elect to obtain the exclusive right to undertake, alone or in collaboration with Fusion, all further clinical or preclinical combination studies combining FPI1434 (or, if applicable, another compound in the Fusion Pipeline) with compounds modulating the applicable Combination Collaboration Target (the “Exclusive Combination Target”), which election may be exercised through written notice to Fusion (the “Exclusive Combination Development Election Notice”) and payment of a Specific Combination Development Exclusivity Fee, with such exclusivity continuing for a period of [***] following the date Fusion receives such Exclusive Combination Development Election Notice (the “Exclusive Combination Target Period”) for a particular Exclusive Combination. Notwithstanding the foregoing, in the event that the reason AstraZeneca is unable to enroll its first patient within [***] period outlined above is due to issues with supply of the Fusion Contributed Compound, then the Parties shall agree to a reasonable extension of such [***] period for the purposes of preserving the rights granted under this Section 2.5.

Development of Exclusive Combination Targets. After delivering an Exclusive Combination Development Election Notice, AstraZeneca shall, as soon as is reasonably possible, provide Fusion with a detailed development plan of the proposed clinical Development, including minimum spend for Development (“Clinical Development Plan”) of a combination of a compound in the AstraZeneca Pipeline (the “AstraZeneca Contributed Compound”) modulating an Exclusive Combination Target with FPI1434 (or, if mutually agreed by the Parties or so elected in accordance with Section 2.7.3, another compound in the Fusion Pipeline) (each such combination an “Exclusive Combination”). Within [***] after its receipt of such Clinical Development Plan, Fusion will notify AstraZeneca in writing whether it elects to jointly Develop an Exclusive Combination (if so elected, a “Jointly Funded Clinical Combination”). If Fusion fails to make such election (including by failing to provide timely notice of such election), AstraZeneca will have the right to solely fund and Develop such Exclusive Combination (an “AstraZeneca Sole Funded Clinical Combination”).

Subsequent Radioconjugates

Fusion shall notify AstraZeneca in writing prior to the initiation of any Clinical Study of FPI1966 and/or [***] undertaken by or on behalf of Fusion, and within [***] after receipt of such notice, by providing written notice to Fusion (a “Subsequent Radioconjugate Notification”), AstraZeneca may elect to exercise the further rights with respect to FPI1966 and/or [***] described in Section 2.7.2 below.

Following its receipt of a Subsequent Radioconjugate Notification, Fusion will (i) promptly provide AstraZeneca with a topline data package of the pre-clinical data on the applicable Fusion Pipeline radioconjugate, (ii) provide AstraZeneca with regular updates on the progress of the Phase 1 Study of such Fusion Pipeline radioconjugate and (iii) update the topline data package delivered pursuant to the forgoing subsection (i) upon completion of a Phase 1 Study of such Fusion Pipeline radioconjugate. Commencing on the date on which Fusion updates the topline data package upon completion of a Phase 1 Study pursuant to the previous sentence and ending [***] thereafter, for (x) all Exclusive Combination Targets, and/or (y) for all Combination Collaboration Targets where the Evaluation Period or the Validation Trial Decision Period has not expired, AstraZeneca shall have an exclusive right, but not an obligation, to elect to initiate a Combination Target Validation Trial, combining FPI1966 or [***] (instead of FPI1434), as applicable, with a compound modulating an Exclusive Combination Target and/or any relevant Combination Collaboration Target (a “Subsequent Radioconjugate Validation Trial”), and if needed jointly (through the JRC) agreed preparatory pre-clinical studies with relevant animal model. The JRC will submit to the JSC for approval an amendment to the Combination Collaboration Plan to include any Subsequent Radioconjugate Validation Trial or any agreed preparatory pre-clinical studies with relevant animal models. AstraZeneca may make the election described in the previous sentence by delivering Fusion a notice of such election and, with respect to a Combination Collaboration Target where the Validation Trial Decision Period has not expired, by paying a Specific Combination Evaluation Exclusivity Fee; it being understood that, for the avoidance of doubt, AstraZeneca will not be required to pay a Specific Combination Evaluation Exclusivity Fee in order to make such election, if such a fee has already been paid for the applicable Exclusive Combination Target or Combination Collaboration Target pursuant to Section 2.4.1.

Upon exercise of its right to conduct a Subsequent Radioconjugate Validation Trial pursuant to Section 2.7.2, on a Combination Collaboration Target by Combination Collaboration Target basis at any time prior to the expiry of the applicable Evaluation Period, AstraZeneca shall be entitled to include FPI1966 and/or [***] (as applicable) as an Exclusive Combination in accordance with Section 2.6 and Section 2.5 upon providing written notice to Fusion and payment of the Specific Combination Development Exclusivity Fee.

Supply of Drug Product for Combination Collaboration

At no cost to AstraZeneca, Fusion will supply, as applicable, FPI1434, FPI1966 or [***] drug product sufficient to support each pre-clinical study, Combination Target Validation Trial and Subsequent Radioconjugate Validation Trial incorporated into the Combination Collaboration Plan, in all cases upon reasonable advance notice, and, with respect to supply for Combination Target Validation Trials and Subsequent Radioconjugate Validation Trials, pursuant to the terms of the applicable Fusion CSA and Fusion QA.

At no cost to Fusion, AstraZeneca will supply drug product for compounds from the AstraZeneca Pipeline modulating all relevant Combination Collaboration Targets for all Combination Target Validation Trials.

De Novo Radioconjugate Collaboration Overview

Overview.

The Parties intend to collaborate to generate, research and validate up to three (3) novel radioconjugates (each such combination a “Joint Radioconjugate”) combining the Fusion Alpha Emitting Platform with antibodies mutually agreed from an initial list provided by AstraZeneca of [***] named targets from the AstraZeneca Pipeline (the “De Novo Radioconjugate Collaboration”).

The De Novo Radioconjugate Collaboration will be divided into the following three types of activity: (i) selection of antibodies to be the subject of the De Novo Radioconjugate Collaboration (“De Novo Target Selection”) as set forth in Section 3.2, (ii) initial pre-clinical and clinical research, ending on completion of the applicable Stage 2 Development Plan, of the selected antibodies conjugated to the Fusion Alpha Emitting Platform, (“De Novo Research”) as set forth in Section 3.3 through Section 3.5 below and (iii) further jointly funded clinical development (“De Novo Development”) as set forth in ARTICLE 6. All activities to be conducted by the Parties during De Novo Target Selection and De Novo Research will be set forth in the De Novo Radioconjugate Collaboration Plan. All activities to be conducted by the Parties during De Novo Development will be set forth in the applicable Joint Development Plan.

De Novo Radioconjugate Collaboration Plan. All activities to be conducted by the Parties during De Novo Target Selection and De Novo Research will be set forth in a plan prepared by the JRC (the “De Novo Radioconjugate Collaboration Plan”) and approved by the JSC. The De Novo Radioconjugate Collaboration Plan shall also include a reasonably detailed budget of the costs and expenses (including FTE Costs) for the activities to be conducted pursuant to such plan (the “De Novo Radioconjugate Collaboration Budget”) on an activity-by-activity or study-by-study basis, as appropriate. The De Novo Radioconjugate Collaboration Plan will be comprised of the Stage 1 Development Plan and Stage 2 Development Plan for all Collaboration Antibodies (as applicable). The Parties intend to amend the De Novo Radioconjugate Collaboration Plan from time to time to incorporate the further research and studies to be conducted pursuant to the terms of this ARTICLE 3. The initial De Novo Radioconjugate Collaboration Plan will reflect the Stage 1 Development Plan for the first Collaboration Antibody selected by the Parties pursuant to Section 3.2 upon the formulation and approval of such Stage 1 Development Plan in accordance with the terms of Section 3.3.1.

Allocation of Contributions. The Parties intend, and the De Novo Radioconjugate Collaboration Plan will reflect, the understanding that, with respect to the allocation of responsibility of the activities by the Parties pursuant to this ARTICLE 3, (i) Fusion will sponsor and operationally run all pre-clinical work and all Clinical Studies (including SAD/MAD Studies primarily aimed at establishing the safety of any Joint Radioconjugate and (ii) AstraZeneca will sponsor and operationally run all other Clinical Studies and (if applicable) the engagement of a CMO in accordance with Section 3.3.3.

Funding. Each Party will be responsible for fifty percent (50%) of the costs (including FTE Costs) set forth in the budget for each Stage 1 Development Plan to be paid in accordance with Section 7.4. If both Parties exercise their option to continue further development of the applicable Joint Radioconjugate pursuant to Section 3.4.2, the Parties will also be responsible for fifty percent (50%) of the costs (including FTE Costs) set forth in the budget for each Stage 2 Development Plan. For the avoidance of doubt, on a Collaboration Antibody by Collaboration Antibody basis, the Stage 1 Exercising Party or Stage 2 Exercising Party will exclusively fund all further activities in connection with such Collaboration Antibody.

Supply of Antibodies. AstraZeneca (whether directly or through its Affiliates or a CMO) will provide a sufficient quantity of material for each of the applicable Collaboration Antibodies for use under each Stage 1 Development Plan and Stage 2 Development Plan at no cost to Fusion and such supply shall be on terms (including customary and reasonable terms relating to ensuring quality and safety reporting) to be agreed in good faith by the Parties and (if applicable) a CMO (any such agreement(s), a “Antibody Supply Agreement”).

Additional Agreements. As and when necessary (as determined by the JRC) the Parties hereby agree to negotiate in good faith and execute such agreements as may be necessary or otherwise appropriate to govern the terms of any Research, Pre-Clinical Studies, and/or Clinical Studies conducted by the Parties during the De Novo Radioconjugate Collaboration on commercially reasonable terms and consistent with this Agreement (including Section 6.5), including agreements relating to supply of materials, quality assurance and safety assurance and reporting.

Antibody Selection

The initial De Novo Radioconjugate Collaboration Plan generated pursuant to Section 3.1.2 will include a list of at least [***] antibodies (and corresponding molecular targets set forth on Appendix 3) [***] made available by AstraZeneca for the De Novo Radioconjugate Collaboration (the “Antibody Collaboration Candidate List”), and for each such antibody, a summary of expression pattern and relevant pre-clinical data. As mutually agreed (through the JRC), the Parties may elect to remove and/or add antibodies and molecular targets from or to the Antibody Collaboration Candidate List (and update Appendix 3 accordingly) until such time that an antibody has been selected as a Collaboration Antibody; provided that at any time the Antibody Collaboration Candidate List shall include at least [***] antibodies (inclusive of Collaboration Antibodies).

In the period commencing with the Effective Date and continuing until the [***] thereof (the “Joint Radioconjugate Selection Period”) the Parties will mutually agree upon up to [***] antibodies (each a “Collaboration Antibody”) from the Antibody Collaboration Candidate List to be used for the De Novo Radioconjugate Collaboration.

Stage 1 Development

Promptly upon selection of a Collaboration Antibody pursuant to Section 3.2.2, the Parties (through the JRC) will prepare and submit to the JSC for approval a detailed development plan (a “Stage 1 Development Plan”) for such Collaboration Antibody. Each Stage 1 Development Plan shall include (i) detailed work streams and budgets (including FTE Costs) for the development of the Collaboration Antibody up until but not including the initiation of Manufacturing in accordance with cGMP and (ii) a summary of the data that should be included in the applicable Stage 1 Data Package. Unless unanimously agreed by the JRC, each Stage 1 Data Package will at a minimum include data [***]. Upon approval by the JSC, the JSC will amend the De Novo Radioconjugate Collaboration Plan to incorporate each Stage 1 Development Plan.

The Parties will provide the JRC with written reports detailing their activities conducted under each Stage 1 Development Plan and the results of such activities at least [***] in advance of each regularly scheduled JRC meeting. The Parties will discuss the status, progress and results of such activities under each Stage 1 Development Plan at such regularly scheduled JRC meetings. Notwithstanding the foregoing, each Party shall notify the other Party promptly upon becoming aware of any information that would reasonably be expected to be material to the applicable Collaboration Antibody during the pendency of the applicable Stage 1 Development Plan.

In parallel with the activities conducted under the Stage 1 Development Plan, AstraZeneca will use its Commercially Reasonable Efforts to develop a suitable stable cell line (unless such a cell line already exists) as well as the ability to perform a technical transfer of the cell line pursuant to Appendix 4 to enable a CMO to manufacture the applicable Collaboration Antibody in compliance with cGMP. For the avoidance of doubt, such activities will not be incorporated into the Stage 1 Development Plan or otherwise in the De Novo Radioconjugate Collaboration Plan.

Stage 1 Option

Fusion shall submit each Stage 1 Data Package to the JRC promptly upon completion thereof, which the JRC shall promptly review for confirmation as to its conformity with the requirements for such Stage 1 Development Plan set forth in the applicable Stage 1 Development Plan. If the JRC makes a determination that such Stage 1 Data Package does not conform to the requirements set forth in the applicable Stage 1 Development Plan, the JRC shall identify such non-conformities and (i) the Parties (through the JRC) will submit an amendment to the applicable De Novo Radioconjugate Collaboration Plan (including the applicable De Novo Radioconjugate Collaboration Budget) for further work to be conducted by Fusion to correct such non-conformities and (ii) Fusion will re-commence activities in accordance with such amended De Novo Radioconjugate Collaboration Plan and re-submit a Stage 1 Data Package to the JRC in accordance with the terms of this Section 3.4.1 upon completion thereof. For avoidance of doubt, AstraZeneca will reimburse Fusion in accordance with Section 7.4.1(ii) for a fifty percent (50%) share of the costs incurred by Fusion under any De Novo Radioconjugate Collaboration Plan amended in accordance with this Section 3.4.1.

Upon confirmation by the JRC that a Stage 1 Data Package is complete, each Party will have [***] to exercise an option to continue further development of the applicable Joint Radioconjugate (the “Stage 1 Radioconjugate Option”).

Stage 2 Development

If both Parties exercise the Stage 1 Radioconjugate Option for a given Joint Radioconjugate, the Parties (through the JRC) will prepare and submit to the JSC for approval a detailed development plan for the cGMP Manufacture, IND preparation and Clinical Studies (including SAD/MAD Studies) primarily aimed at establishing safety for the applicable Joint Radioconjugate (a “Stage 2 Development Plan”). Each Stage 2 Development Plan shall include (i) detailed work streams and budgets (including FTE Costs) for the activities to be conducted and (ii) a summary of the data that should be included in the applicable Stage 2 Data Package. Upon approval by the JSC, the JSC will amend the De Novo Radioconjugate Collaboration Plan to incorporate each Stage 2 Development Plan.

Collaboration Antibody Supply. The Stage 2 Development Plan will reflect that AstraZeneca will take lead on (and, notwithstanding anything to the contrary in this Agreement, will have the final decision-making authority on) the Manufacture of the applicable naked Collaboration Antibody in compliance with GMP whether directly (or through its Affiliates or through the engagement of a CMO, including (if applicable) serving as the primary contracting Party with respect to any agreements with a CMO. When choosing a CMO, AstraZeneca shall give due consideration to reducing the overall project timelines and consider in good faith any reasonable input from Fusion. If applicable, such supply shall be provided by AstraZeneca pursuant to one or more Antibody Supply Agreements. Fusion will use its Commercially Reasonable Efforts to generate the Stage 1 Data Packages and Stage 2 Data Packages in accordance with the timelines and budget set forth in the De Novo Radioconjugate Collaboration Plan.

The Parties will provide the JRC with written reports detailing their activities conducted under each Stage 2 Development Plan and the results of such activities at least [***] in advance of each regularly scheduled JRC meeting. The Parties will discuss the status, progress and results of such activities under each Stage 2 Development Plan at such regularly scheduled JRC meetings. Notwithstanding the foregoing, each Party shall notify the other Party promptly upon becoming aware of any information that would reasonably be expected to be material to the Development of any Joint Radioconjugate during the pendency of the applicable Stage 2 Development Plan.

Upon reaching mutual agreement (through the JRC) that a Stage 2 Data Package is completed, each Party will have [***] to exercise an option to continue further development of the applicable Joint Radioconjugate (the “Stage 2 Radioconjugate Option”).

If both Parties exercise their respective Stage 2 Radioconjugate Option for a given Collaboration Antibody, such Collaboration Antibody will be deemed a “Joint Development Radioconjugate” and be further Developed and Commercialized in accordance with ARTICLE 6.

Single Party Development. If only one Party exercises its respective Stage 1 Radioconjugate Option or Stage 2 Radioconjugate Option for a given Collaboration Antibody (the “Stage 1 Exercising Party” and the “Stage 2 Exercising Party” respectively, or, generally the “Exercising Party”), the Parties will enter into good faith negotiations for a commercially reasonable agreement pursuant to which the Exercising Party will obtain an exclusive license (including applicable Fusion Background IP or AstraZeneca Background IP, as applicable) to the applicable Joint Radioconjugate (the “Single Party Development Radioconjugate”) which, among other commercially reasonable terms, will include the terms set forth on Appendix 4.

Applicable Laws and Bioethics. The activities to be conducted by each Party (including by its subcontractors) pursuant to this Agreement will be carried out in good scientific manner, and in compliance with all Applicable Laws. In addition, Fusion will, and will cause its Affiliates and subcontractors to carry out their activities under each Collaboration Program in compliance with the AstraZeneca bioethics policy attached at Appendix 5.

Joint Steering Committee. Within [***] of the Effective Date, the Parties will establish a joint steering committee (“JSC”), to provide overall strategic guidance, conflict resolution, and oversight over the Collaboration Programs and approve the Collaboration Plans and Combination Collaboration Budgets and plans and budgets for Joint Development Radioconjugates and Jointly Funded Clinical Combinations proposed by the JDC and JRC as well as plans proposed by other sub-committees. The JSC will consist of [***] senior management representatives appointed by Fusion and [***] senior management representatives appointed by AstraZeneca. As reasonable and appropriate, other employee representatives or agents of the Parties may attend JSC meetings as non-voting observers or presenters. Each Party will be responsible for the costs of its own employees or consultants attending JSC meetings.

Meetings. The JSC will meet at least [***] during the Agreement Term or as otherwise mutually agreed. Such meetings may be held via remote videoconference or teleconference or another method mutually agreeable to the Parties; provided that, unless otherwise agreed by the Parties, at least [***] will be in person in a location to be agreed by the Parties. In addition, either Party may also call a special meeting of the JSC (including by videoconference or teleconference) upon at least [***] prior written notice to the other Party if such Party reasonably believes that a significant matter must be addressed before the next regularly scheduled meeting, and such Party will provide the JSC, no later than [***] before the special meeting, with materials reasonably adequate to enable an informed decision to be made by its members.

Joint Development

Overview. The Parties desire and intend to collaborate with respect to the Development of each Jointly Funded Clinical Combination and each Joint Development Radioconjugate as designated pursuant to the terms of ARTICLE 2 and ARTICLE 3, respectively.

Joint Development Plans. Promptly upon designation of a Jointly Funded Clinical Combination and or a Joint Development Radioconjugate, the Parties will meet (through the JDC) to prepare (or in the case of a Jointly Funded Clinical Combination, update as necessary the applicable Clinical Development Plan) and submit to the JSC for approval a detailed development plan setting forth all Development activities to be conducted with respect to such Jointly Funded Clinical Combination and or a Joint Development Radioconjugate (each a “Joint Development Plan”). In addition, each Joint Development Plan shall also include a reasonably detailed budget of the costs and expenses (including FTE Costs) for the activities to be conducted pursuant to such plan (the “Joint Development Budget”) on an activity-by-activity or study-by-study basis, as appropriate.

The Parties intend, and each Joint Development Plan will reflect that AstraZeneca will sponsor and operationally run all clinical trials conducted under each Joint Development Plan.

The JDC will periodically (or at the request of one of the Parties) review each then-current Joint Development Plan, and if the JDC determines an amendment is needed to a then-current Joint Development Plan, the JDC will collaborate to prepare an amendment to such then-current Joint Development Plan, for review, comment and approval by the JSC. Such amended Joint Development Plan will reflect any changes (including additions) to the applicable Joint Development Budget. Once approved by the JSC, such amended Joint Development Plan will become effective and supersede the previous Joint Development Plan as of the date of such approval.

Performance. Each Party will use its Commercially Reasonable Efforts to conduct the Development activities allocated to such Party, if any, in each Joint Development Plan in a timely and effective manner.

Development Costs. Unless otherwise set forth in an approved Joint Development Plan, all costs and expenses (including FTE Costs) set forth in the applicable Joint Development Budget will be paid 50% by Fusion and 50% by AstraZeneca.

Independent Development. Except as set forth in this Section 6.2, AstraZeneca shall have the sole right to Develop each AstraZeneca Sole Funded Clinical Combination, at its sole cost, expense and direction. AstraZeneca will provide the JDC a study schematic prior to initiating any Clinical Study of a AstraZeneca Sole Funded Clinical Combination and will keep the JDC reasonably informed of the status and progress of such Clinical Study after initiation. The JDC will discuss and approve (and AstraZeneca will implement upon such approval) any changes to the plan or execution of such Clinical Study solely to the extent such change is proposed as a solution to Fusion’s reasonable concern that such Clinical Study (or any aspect thereof) would have a material adverse impact on the safety profile of the applicable compound in the Fusion Pipeline.

Development Supply

Supply by Fusion.

At no cost to AstraZeneca, Fusion will supply, as applicable, FPI1434, FPI1966 or [***] drug product sufficient to support (i) each AstraZeneca Sole Step In Trial and (ii) clinical trials conducted, under a Joint Development Plan and with respect to AstraZeneca Sole Funded Clinical Combinations, in each case, pursuant to the terms of the applicable Fusion CSA and Fusion QA.

Prior to initiation of any AstraZeneca Sponsored Clinical Study as part of the Combination Collaboration, the Parties will negotiate in good faith and enter into a clinical supply agreement (each a “Fusion CSA”) and quality agreement (each a “Fusion QA”) with respect to Fusion’s supply of (as applicable) FPI1434, FPI1966 or [***] drug product. Each Fusion CSA and Fusion QA shall contain mutually agreed terms and conditions consistent with this Agreement including Section 2.8.1 and Section 6.3.1(a), in addition to other terms that are reasonable and customary, including provisions to ensure quality and audit by or on behalf of AstraZeneca.

Supply by AstraZeneca. At no cost to Fusion, AstraZeneca will supply drug product for AstraZeneca Contributed Compounds for all applicable Exclusive Combination Targets sufficient to support each Clinical Study conducted under a Joint Development Plan.

AstraZeneca Step In. In the event that either (or both) Parties propose to the JDC to undertake a Clinical Study in furtherance of a Jointly Funded Clinical Combination or Joint Development Radioconjugate that would require an amendment to the applicable Joint Development Plan and Joint Development Budget, or require an increase to the Joint Development Budget for an already agreed Clinical Study, and Fusion, by providing AstraZeneca written notice or the exercise of a JDC or JSC vote, declines to provide funding to such Clinical Study or increase to the Joint Development Budget for an already agreed Clinical Study, then AstraZeneca may undertake such Clinical Study or increase the budget of an existing Clinical Study, at its sole cost and expense, independently and outside of the scope of the applicable Joint Development Plan and/or Joint Development Budget (each a “AstraZeneca Sole Step In Trial”).

Clinical Study Regulatory and Safety Matters. The following provisions shall apply for each AstraZeneca Sponsored Clinical Study and Fusion Sponsored Clinical Study conducted pursuant to this Agreement.

The applicable Study Sponsor shall be responsible for submitting, obtaining and maintaining all necessary approvals and clearances, including any new INDs, CTAs or other Regulatory Approvals and customs clearances, for the conduct of the applicable Clinical Study. The Study Sponsor shall be responsible for the preparation and submission of all regulatory filings relating to the applicable Clinical Study and shall ensure all directions from any Regulatory Authority and/or ethics committee with jurisdiction over the Clinical Study are followed. The other Party shall provide the Study Sponsor with all assistance or supporting information to the extent reasonably necessary for the Study Sponsor to exercise its rights and obligations under this Section 6.5.1, including, upon a Study Sponsor’s written request, authorizing the cross-referencing of any INDs and CTAs held by such Party to the extent necessary to support the conduct of the applicable Clinical Study, and shall execute any documents or instruments necessary to allow such cross-referencing.

The Study Sponsor shall be responsible for compliance with all Applicable Laws pertaining to safety reporting for the applicable Clinical Study and related activities. Unless otherwise agreed, the Parties shall execute a pharmacovigilance agreement for each applicable Clinical Study (each a “Pharmacovigilance Agreement”) prior to the initiation of any Clinical Study carried out under this Agreement, to ensure the exchange of relevant safety data within appropriate timeframes and in an appropriate format to enable the Parties and their Affiliates to fulfil their regulatory reporting requirements and facilitate appropriate safety reviews.

The applicable Study Sponsor shall be wholly accountable and liable for the safety, health and environmental (“SHE”) aspects of the conduct of such Clinical Studies, including the handling and destruction of all compounds in the Fusion Pipeline and/or AstraZeneca Pipeline used in the applicable study and shall operate risk management systems, which (i) ensure that the risks and impact of any activity undertaken are assessed and (ii) ensure that appropriate actions are taken to mitigate against any hazards identified.

Regulatory Matters.

At each regularly scheduled meeting of the JDC, the Parties will discuss and approve the regulatory strategy with respect to Joint Development Radioconjugates and Exclusive Combinations, including, on a country-by-basis, determining whether a particular Combination Product can be Commercialized as an Extricable Combination Product or an Inextricable Combination Product, it being acknowledged that the first preference is that Combination Products will be Commercialized as Extricable Combination Products. Such regulatory strategy shall be informed by, among other relevant factors, regular discussions with applicable Regulatory Authorities. All Data generated from Joint Development Plans, AstraZeneca Sole Step In Trials and any independent activities conducted by AstraZeneca with respect to AstraZeneca Sole Funded Clinical Combinations may be considered by the JDC in such determination and included in either Party’s filings with regulatory filings made pursuant to this Section 6.6.

On a country-by-country basis, for all Extricable Combination Products, each Party will be responsible for at their sole cost and expense, and will use their respective Commercially Reasonable Efforts to, prepare, file and maintain Regulatory Approvals for (i) with respect to Fusion, the Fusion Contributed Compound Product, and (ii) with respect to AstraZeneca, the AstraZeneca Contributed Compound Product. Each Party hereby grants the other Party a Right of Reference in the Territory to the applicable Regulatory Materials for the Contributed Product of the granting Party solely for purposes of seeking such Regulatory Approval. The Parties shall coordinate with each other in good faith on the timing and filing of their respective Regulatory Approvals for their respective component of the applicable Extricable Combination Product, taking into account the other Party’s efforts to seek Regulatory Approval for its component of the applicable Extricable Combination Product.

AstraZeneca will be responsible for preparing, filing and maintaining Regulatory Approvals for Inextricable Combination Products and Joint Development Radioconjugates in accordance with the applicable Joint Development Plan. Fusion will assist and reasonably cooperate with AstraZeneca in connection with the preparation of such Regulatory Approvals and submissions, as reasonably requested by AstraZeneca. AstraZeneca will keep Fusion reasonably informed of regulatory developments relating to such regulatory activities.

Right to Participate in Regulatory Activities. With respect to any interactions with Regulatory Authorities in the Territory relating to Regulatory Approval of a Combination Product (or the Contributed Product included therein) pursuant to either Section 6.5.1, Section 6.6.2 or Section 6.6.3, except with respect to interactions with Regulatory Authorities that relate solely to a Party’s Contributed Product, each Party will permit the other Party to review, comment on and/or participate in, any material interactions related thereto with Regulatory Authorities in the Territory to the extent relating to such other Party’s Contributed Product and will consider in good faith any comments relating to such regulatory interactions.

Joint Development Radioconjugate RoFN. On a Joint Development Radioconjugate by Joint Development Radioconjugate basis, (i) before Fusion commences any non-preliminary discussions with any Third Party regarding a transaction (other than a change of control of Fusion) to license, sell, transfer or divest its interest in a Joint Development Radioconjugate (a “ROFN Transaction”) or (ii) if Fusion receives an unsolicited offer from a Third Party for a ROFN Transaction, then prior to commencing or continuing any non-preliminary discussions or negotiations with any such Third Party, Fusion shall first promptly notify AstraZeneca in writing of its intent or receipt of such offer (as applicable) (an “ROFN Notice”); which notice shall include (as applicable) a high-level summary of such proposed ROFN Transaction and the following provision shall then apply:

AstraZeneca shall have [***] after receipt of such ROFN Notice (the “ROFN Election Period”) to elect to enter into exclusive negotiations with respect to such ROFN Transaction. During the ROFN Election Period, Fusion and its Affiliates shall not conduct discussions, or negotiate, with any Third Party with respect to such ROFN Transaction.

If AstraZeneca elects to enter into exclusive negotiations during the ROFN Election Period, Fusion shall negotiate exclusively and in good faith with AstraZeneca to finalize and execute a definitive agreement (or an amendment to this Agreement) setting forth the terms of the ROFN Transaction for a period commencing upon the date Fusion receives notice of such election from AstraZeneca and expiring [***] thereafter (the “ROFN Negotiation Period”).

With respect to any ROFN Transaction if (i) AstraZeneca does not elect to enter into exclusive negotiations with respect to such ROFN Transaction in accordance with Section 6.8.1 or (ii) a definitive agreement (or an amendment to this Agreement) is not executed prior to the expiration of the ROFN Negotiation Period in accordance with Section 6.8.2, then (in the case of either of (i) or (ii)) AstraZeneca shall no longer have the exclusive right to negotiate such ROFN Transaction (a “ROFN Expiration”) and Fusion, at its sole discretion, may proceed to negotiate and seek to enter into and consummate such ROFN Transaction with a Third Party; provided, however, any such ROFN Transaction shall in no case be on material terms (when taken as a whole) less favorable (to Fusion) than the terms offered by AstraZeneca during the ROFN Negotiation Period.

Commercialization of Joint Development Radioconjugates. On a Joint Development Radioconjugate by Joint Development Radioconjugate basis, promptly following initiation of planning for an initial registrational trial (or at any time during clinical development under a Joint Development Plan if mutually agreed), the Parties will discuss in good faith the commercially reasonable terms of a license granting AstraZeneca exclusive rights to the relevant De Novo IP Rights and an exclusive license to applicable Fusion Background IP solely with respect to the molecular target of the De Novo Radioconjugate to Commercialize and further Develop the Joint Development Radioconjugate. Subject to Section 6.11, if after [***] of commencing such discussions, the Parties fail to agree on such commercially reasonable terms, the Parties will promptly negotiate in good faith commercially reasonable terms and conditions of a co-commercialization agreement pursuant to which they will jointly Commercialize and further Develop the Joint Development Radioconjugate with such negotiations being based on the premise that the Parties have made equal contributions to the development of the Joint Development Radioconjugates subject only to AstraZeneca funding through AstraZeneca Sole Step In Trials under Section 6.4, if applicable. The terms and conditions for such co-commercialization agreement shall be based on the principles set forth in Appendix 6. In the event that after [***] of commencing negotiations pursuant to this Section 6.9 (or such other period of time as the Parties may agree) the Parties cannot agree on either (i) the terms of a license granting AstraZeneca such exclusive rights to the relevant De Novo IP Rights and an exclusive license to applicable Fusion Background IP solely with respect to the molecular target of the De Novo Radioconjugate to Commercialize and further Develop the Joint Development Radioconjugate or (ii) the terms of a co-commercialization agreement pursuant to which they will jointly Commercialize and further Develop the Joint Development Radioconjugate, then such Joint Development Radioconjugate shall not be Commercialized by either Party and the licenses granted by Fusion to AstraZeneca under Section 8.6.1 and by AstraZeneca to Fusion under Section 8.7.1 will terminate with respect to such Joint Development Radioconjugate.

Exclusive Combination Commercialization.

With respect to Extricable Combination Products, each Party will have the sole right, and will use their respective Commercially Reasonable Efforts to Commercialize their respective Contributed Products as a component of the applicable Extricable Combination Product in the Territory and shall bear their own costs and expenses incurred in connection with such Commercialization activities. Each Party hereby agrees to provide the other Party reasonable assistance with respect to the Commercialization of their respective Contributed Products sold as a component of an Extricable Combination Product and to coordinate their activities with respect thereto through the JCC including as may be required under Applicable Law. Other than as set forth in Section 6.12 or as may otherwise be agreed by the Parties, neither Party shall be entitled to any royalty or will otherwise share in any revenue received from the other Party’s Commercialization of a Contributed Product sold as a component of an Extricable Combination Product.

On a country-by-country basis, as soon as practicable following the determination that a Combination Product is an Inextricable Combination Product, the Parties will negotiate in good faith terms and conditions, including license terms regarding licensing of Fusion Background IP and AstraZeneca Background IP, as applicable, of a co-commercialization agreement pursuant to which they will jointly Commercialize an Inextricable Combination Product.

Step In Trial Cost Repayment. On a country-by-country basis, if Regulatory Approval of any Joint Development Radioconjugate, Inextricable Combination Product or a Fusion Pipeline Product in any Indication in the Territory is granted predominantly as a result of an AstraZeneca Sole Step In Trial, AstraZeneca shall be entitled to recover an amount equal to [***]. Fusion shall pay the foregoing amounts to AstraZeneca in accordance with a payment schedule mutually agreed by the Parties through the JCC. For the avoidance of doubt, the Parties agree that if AstraZeneca solely funds a Phase 3 Study for a Joint Development Radioconjugate, Inextricable Combination Product or a Fusion Pipeline Product that subsequently receives Regulatory Approval, such Regulatory Approval will be deemed “granted predominantly as a result of an AstraZeneca Sole Step In Trial” for the purposes of this Section 6.11.

Sole Funded Trial Cost Repayment. On a country-by-country basis, if Regulatory Approval of a specific Indication for an Inextricable Combination Product or of a Fusion Contributed Compound Product in any Indication in the Territory, in each case, is granted predominantly as a result of AstraZeneca Sole Funded Clinical Development (“Sole Funded Approval”), then:

if the Sole Funded Approval [***], then:

with respect to such Extricable Combination Product, upon the later of, at Fusion’s sole discretion, (i) the date the Sole Funded Approval is granted and (ii) the date on which Fusion receives Regulatory Approval for the corresponding Fusion Contributed Compound Product in an Extricable Combination Product, Fusion will use its Commercially Reasonable Efforts to make the First Commercial Sale of such Fusion Pipeline Product, either directly or through a partner, within [***] of such Regulatory Approval. In addition, if after such First Commercial Sale, Fusion desires to discontinue sales of the applicable Fusion Pipeline Product, then, prior to discontinuing sales of such Fusion Pipeline Product in such country, Fusion shall notify AstraZeneca in writing of its intent and, at AstraZeneca’s sole discretion, the Parties shall enter into good faith negotiations for a commercially reasonable agreement for AstraZeneca or its Affiliate to obtain a license under the Intellectual Property Controlled by Fusion (including applicable Fusion Background IP) at such time as necessary to permit AstraZeneca to Commercialize the Extricable Combination Product in such country on payment and other terms to be agreed; and

AstraZeneca shall be entitled to recover an amount equal to [***] of the applicable Sole Funded Trial Cost in accordance with a payment schedule mutually agreed by the Parties through the JCC. In case the JCC fails to approve such payment schedule, Fusion will pay such amount through [***] royalty to AstraZeneca on quarterly Net Sales of the applicable Fusion Pipeline Product beginning upon Fusion’s First Commercial Sale of the Fusion Pipeline Product and continuing until such balance is paid, solely to the extent such First Commercial Sale and such Net Sales of the Fusion Pipeline Product are directly attributable to the sales of a Combination Product (whether as an Extricable Combination Product or an Inextricable Combination Product) in accordance with Section 7.4 and/or Section 7.4.2 (as applicable).

if the Sole Funded Approval was [***], then:

with respect to an Extricable Combination Product, Fusion will use its Commercially Reasonable Efforts to ensure that the applicable Fusion Pipeline Product remains available for sale in such country, either directly or through a

AstraZeneca shall be entitled to recover an amount equal to [***] of the applicable Sole Funded Trial Cost in accordance with a payment schedule mutually agreed by the Parties through the JCC. In case the JCC fails to approve such payment schedule, Fusion will pay such amount through a [***] royalty to AstraZeneca on quarterly Net Sales of the applicable Fusion Pipeline Product beginning upon Fusion’s First Commercial Sale of the Fusion Pipeline Product and continuing until such balance is paid, solely to the extent such First Commercial Sale and such Net Sales of the Fusion Pipeline Product are directly attributable to the sales of a Combination Product (whether as an Extricable Combination Product or an Inextricable Combination Product), in accordance with Section 7.4 and/or Section 7.4.2 (as applicable).

For the avoidance of doubt, on a Fusion Pipeline Product by Fusion Pipeline Product basis, the obligation to reimburse AstraZeneca for the Step In Trial Cost pursuant to Section 6.11 or the Sole Funded Trial Cost pursuant to Section 6.12 shall apply with respect to all countries in the Territory in which Net Sales of Fusion Pipeline Products occur which are directly attributable to the sales of a Combination Product (whether as an Extricable Combination Product or an Inextricable Combination Product), in accordance with Section 7.4 and/or Section 7.4.2 (as applicable).

For the avoidance of doubt, the Parties agree that if AstraZeneca solely funds a Phase 3 Study that leads to Regulatory Approval being granted for an Inextricable Combination Product or Fusion Contributed Compound Product, then such Regulatory Approval will be deemed “granted predominantly as a result of AstraZeneca Sole Funded Clinical Development” for the purposes of this Section 6.12.

Up-Front Fee. In consideration for the exclusive rights and options granted by Fusion hereunder, AstraZeneca will pay Fusion an up-front fee of five million dollars ($5,000,000) within forty-five (45) days of receipt of an invoice from Fusion for such amount.

Milestone Payments for Achievement of Milestone Events by a Product. In consideration for the achievement thereof, AstraZeneca will pay to Fusion, in accordance with Section 7.4, the milestone payments as set forth in TABLE 1 below:

For purposes of this Section 7.2, [***].

For purposes of this Section 7.2, [***].

Each milestone payment set forth in TABLE 1 above will be paid only once upon the first achievement of the milestone event.

Each time a milestone event is achieved under this Section 7.2, Fusion will send AstraZeneca a written notice thereof following the date of achievement of such milestone event along with documentation evidencing such achievement and an invoice with the applicable payment. Such milestone payment will be due within [***] after AstraZeneca’s receipt of such invoice.

Exclusivity Payments. In consideration for the grants of exclusivity set forth in Section 2.5 in connection with the Combination Collaboration, AstraZeneca will pay to Fusion the following fees within [***] of issuing the applicable election notice:

[***] in the event that AstraZeneca issues a Combination Target Validation Trial Notice (the “Specific Combination Evaluation Exclusivity Fee”).

[***] in the event that AstraZeneca issues an Exclusive Combination Development Election Notice (the “Specific Combination Development Exclusivity Fee”).

The Parties will discuss such disputed invoice in good faith within [***] after the non-disputing Party acknowledges the invoice has been disputed, which shall be no less [***] after receipt, whereby the non-disputing Party shall provide all evidence as may be reasonably necessary to verify such disputed invoice. Should the Parties fail to resolve the disputed amount after such discussion, in addition to any other rights granted to it under this Agreement, the disputing Party shall retain its right to audit in accordance with Section 7.8.

Fusion Royalty Payment. Beginning with the Calendar Quarter in which the First Commercial Sale for the applicable Fusion Contributed Compound Product is made and for each Calendar Quarter thereafter until such payment obligations are extinguished, if applicable, Fusion will make royalty payments described in Section 6.12.1(b) and/or Section 6.12.2(b) to AstraZeneca within [***] following the end of each such Calendar Quarter. Each royalty payment will be accompanied by a report, summarizing Net Sales for Fusion Contributed Compound Products during the relevant Calendar Quarter and the calculation of royalties due thereon, including country, units, sales price and the exchange rate used. If no royalties are payable in respect of a given Calendar Quarter, Fusion will submit a written royalty report to the other Party so indicating.

Mode of Payment. All payments under this Agreement will be (i) payable in full in U.S. dollars, (ii) made by wire transfer of immediately available funds to an account designated by the payee Party in writing, and (iii) non-creditable, and non-refundable. Whenever for the purposes of calculating the royalties payable under this Agreement conversion from any foreign currency will be required, all amounts will first be calculated in the currency of sale and then converted into U.S. dollars at the USD Exchange Rate.

Records Retention. Each Party will keep complete and accurate records in sufficient detail as are required to determine (i) as applicable, the amounts invoiced to the other Party pursuant to Section 7.4 and (ii) with respect to Fusion, Fusion’s royalty payment made pursuant to Section 7.4.3 (including the calculation of Net Sales). The applicable Party will maintain such records until the later of (a) [***] after the end of the period to which such records pertain, (b) the expiration of the applicable tax statute of limitations (or any extensions thereof), or (c) such longer period as may be required by Applicable Law.

Audits. During the Agreement Term and for a period of [***] thereafter, at the request and expense of a Party (the “Auditing Party”), the other Party (the “Non-Auditing Party”), will permit an independent certified public accountant of internationally recognized standing appointed by the Auditing Party and reasonably acceptable to the Non-Auditing Party, at reasonable times and upon reasonable notice, but in no case more than [***], to examine such records as may be necessary for the purpose of verifying the calculation of (i) if AstraZeneca is the Auditing Party, Fusion’s royalty payment made pursuant to Section 7.4.3 (including the calculation of Net Sales), and/or (ii) payments made for costs invoiced to the Auditing Party pursuant to (as applicable) Section 7.4.1 or Section 7.4.2. As a condition to examining any records of the Non-Auditing Party, such auditor will sign a nondisclosure agreement reasonably acceptable to the Non-Auditing Party in form and substance. Any and all records of the Non-Auditing Party examined by such independent certified public accountant will be deemed the Non-Auditing Party’s Confidential Information. Upon completion of the audit, the accounting firm will provide both Parties with a written report disclosing whether the applicable payments are correct or incorrect and the specific details concerning any discrepancies (“Audit Report”). If, as a result of any inspection of the books and records of the Non-Auditing Party, it is shown that the applicable payments were more or less than the amount which should have been paid, then the relevant Party will make all payments required to be made by paying the other Party the difference between such amounts to eliminate any discrepancy revealed by said inspection within [***] of receiving the Audit Report, with interest calculated in accordance with Section 7.10. The Auditing Party will pay for such audit, except that if the Non-Auditing Party is found to have miscalculated the applicable payment by more than [***] of the amount that should have been paid for the audited period, the Non-Auditing Party will reimburse Non-Exercising Party the reasonable fees and expenses charged by the accounting firm for the audit.

Taxes.

Taxes On Income. Each Party alone will be solely responsible for paying any and all Taxes (other than withholding taxes required by Applicable Law to be paid by AstraZeneca or Fusion (as the case may be) levied on account of, or measured in whole or in part by reference to, the income of such Party.

Indirect Taxes.

All payments are exclusive of Indirect Taxes. If any Indirect Taxes are chargeable in respect of any payments, for which the receiving Party is liable to remit to the Governmental Authority or other fiscal authority, the paying Party will pay such Indirect Taxes at the applicable rate in respect of such payments following receipt, where applicable, of an Indirect Taxes invoice in the appropriate form issued by the receiving Party in respect of those payments. Any reimbursements of costs are exclusive of any Indirect Taxes which the party incurring the costs is eligible to recover by way of input tax credit or refund.

The Parties will issue invoices for all amounts payable under this Agreement consistent with Indirect Tax requirements and irrespective of whether the sums may be netted for settlement purposes. To the extent, in any circumstances, the paying Party has paid indirect taxes to the receiving Party which it subsequently determines was in excess of the indirect taxes actually due, then the receiving Party shall repay the excess amount to the paying Party within [***] of receipt of a refund from the applicable Governmental Authority or other fiscal authority. The Parties agree to reasonably cooperate to provide any information required by the Party pursuing a refund of Indirect Taxes paid. The receiving Party agrees not to seek compensation from the paying Party in respect of any interest or penalties imposed on the receiving Party if the receiving Party improperly reduces or eliminates Indirect Tax.

Withholding Tax. To the extent the paying Party is required to deduct and withhold taxes on any payment under applicable law, provided the paying Party is resident for tax purposes in the UK, Sweden, US or Canada, the paying Party will pay the amounts of such taxes to the proper governmental authority for the account of the receiving Party and remit the net amount to the receiving Party in a timely manner. To the extent the paying Party is required to deduct and withhold taxes on any payment under applicable law and the paying Party is resident for tax purposes in a territory other than the UK, Sweden, US or Canada, any amount payable under this Agreement shall be increased to take into account such withheld taxes as may be necessary so that, after making all required withholdings, the receiving Party receives an amount equal to the sum it would have received had payment been made directly by AstraZeneca or Fusion, as the case may be, provided that if the receiving Party receives credit or repayment in respect of any tax withheld, it shall reimburse the paying Party for the relevant withholding tax for such credit or repayment. Notwithstanding the foregoing, to the extent that it is possible to secure an exemption from, or a reduction in, any withholding taxes then the receiving Party shall provide such documentation necessary to secure such an exemption from, or reduction in withholding taxes, a minimum of [***] before the date on which the payment attracting such withholding taxes is due; if such documentation is not provided within the timeframe provided, the amount by which the paying Party shall increase amounts payable under this Agreement shall be limited to the minimum amount of withholding taxes which would have been payable had the exemption from, or a reduction in, withholding taxes been secured. In accordance with the procedures set forth in Section 10.3 and Section 10.4, the receiving Party will also indemnify the paying Party for any tax, interest or penalties imposed on the paying Party if the paying Party improperly reduces or eliminates withholding tax based upon representations made by the receiving Party.

Tax Cooperation. At least [***] prior to the date a given payment is due under this Agreement, the non-paying Party will provide the paying Party with any and all tax forms that may be reasonably necessary or reasonably requested in order for the paying Party to lawfully not withhold tax or to withhold tax at a reduced rate with respect to such payment under an applicable bilateral income tax treaty. Following the paying Party’s timely receipt of such tax forms from the non-paying Party, the paying Party will not withhold tax or will withhold tax at a reduced rate under an applicable bilateral income tax treaty, if appropriate under the Applicable Laws. Each Party will provide the other with reasonable assistance to enable the recovery, as permitted by Applicable Law, of withholding taxes resulting from payments made under this Agreement, such recovery to be for the benefit of the Party who would have been entitled to receive the money but for the application of withholding tax under this Section 7.9.

AstraZeneca and Fusion will mutually control and be responsible for all aspects of the Prosecution and Maintenance of all Patent Rights included in or arising from the De Novo IP Rights (the “De Novo Patents”), subject to the below:

The Parties will mutually agree on patent counsel for the Prosecution and Maintenance of De Novo Patents, and such patent counsel will be engaged by both Parties. All decisions and strategic aspects with respect to the Prosecution and Maintenance of the De Novo Patents will be as mutually agreed, except that AstraZeneca will have decision making authority on determining the time of filing of De Novo Patents in the event the Parties cannot mutually agree on such timing. Each Party will have access to all material data as it arises, any office actions or office action responses or other correspondence that either Party provides to or receives from any patent office, including notice of all interferences, reissues, re-examinations, oppositions or requests for patent term extensions, and all patent-related filings and proposed filings.

If either Party elects (i) not to file and prosecute patent applications for the De Novo Patents, (ii) not to continue the prosecution or maintenance of any De Novo Patents in a particular country, then such Party will so notify the other Party promptly in writing of its intention in good time to enable such other Party to meet any deadlines by which an action must be taken to establish or preserve any such Patent Right in such country; in which case the declining Party will, and will cause its Affiliates to, assign to the other Party (or, if such assignment is not possible, grant a fully-paid exclusive license in) all of their rights, titles and interests in and to such De Novo Patent in the applicable country.

In respect of Patent Rights Controlled solely by Fusion, AstraZeneca shall have the right to review and comment, and Fusion shall, in good faith, take into account such review and comment, on any aspect of the Prosecution and Maintenance of such Patent Rights to the extent that such Patent Rights incorporate Data solely owned by AstraZeneca.

If AstraZeneca fails to commence a suit to enforce a De Novo Patent against such Third Party Infringement, or to settle or otherwise secure the abatement of such Third Party Infringement within [***] after written notice of such Third Party Infringement (or such shorter period of time as is required to comply with Applicable Law), then Fusion may commence a suit or take action to enforce such De Novo Patent against such Third Party Infringement at its own cost and expense. In this case, each Party agrees it will take appropriate action to enable the other Party to commence a suit or take the actions set forth in the preceding sentence.

Cooperation. Each Party will provide to the enforcing Party reasonable assistance in such enforcement, at such enforcing Party’s request and expense, including executing all necessary and proper documents and if required to establish and maintain standing to join such action as a thirty party plaintiff if required by Applicable Law to pursue such action. The enforcing Party will keep the other Party reasonably informed of the status and progress of such enforcement efforts.

Settlement. Neither Party will settle any claim, suit or action involving a De Novo Patent that it brought under Section 8.4.2 in any manner that would (i) limit the scope, validity or enforceability of the De Novo Patent anywhere in the Territory, (ii) admit to any fault or wrongdoing by the other Party or any of its Affiliates or (iii) provide for any relief against the other Party or any of its Affiliates, in each case, without the prior written consent of the other Party, which consent will not be unreasonably withheld, conditioned or delayed.

Recoveries. The enforcing Party bringing a claim, suit, or action involving a De Novo Patent that it brought under Section 8.4.2 will pay for any expenses incurred by such Party as a result of such claim, suit, or action. If such Party recovers monetary damages in such claim, suit or action, such recovery will be allocated first to the reimbursement of any expenses incurred by the Parties in such litigation, and any remaining amounts will be [***].

Defense of Claims Brought by Third Parties. If either Party becomes aware of any Third Party’s claim or assertion that any Product infringes a Patent Right granted by a jurisdiction within the Territory, such Party will promptly notify the other Party and the Parties will work toward their shared, mutual interest in the outcome of such potential dispute, and thereafter, the Parties will promptly meet to consider such claim and the appropriate course of action.

AstraZeneca agrees to defend Fusion, its Affiliates and their respective directors, officers, stockholders, employees and agents, and their respective successors, heirs and assigns (collectively, the “Fusion Indemnitees”), and will indemnify and hold harmless the Fusion Indemnitees, from and against any liabilities, losses, costs, damages, fees or expenses payable to a Third Party, and reasonable attorneys’ fees and other legal expenses with respect thereto (collectively, “Losses”) arising out of any claim, action, lawsuit or other proceeding by a Third Party (collectively, “Third Party Claims”) brought against any Fusion Indemnitee and resulting from or occurring as a result of: [***]; except in any such case to the extent such Losses result from: [***].

Indemnification by Fusion. Fusion agrees to defend AstraZeneca, its Affiliates and their respective directors, officers, stockholders, employees and agents, and their respective successors, heirs and assigns (collectively, the “AstraZeneca Indemnitees”), and will indemnify and hold harmless the AstraZeneca Indemnitees, from and against any Losses arising out of Third Party Claims brought against any AstraZeneca Indemnitee and resulting from or occurring as a result of: [***]; except in any such case to the extent such Losses result from: [***].

Notice of Claim. All indemnification claims provided for in Section 7.9.3, Section 10.1, and Section 10.2 will be made solely by such Party to this Agreement (the “Indemnified Party”). The Indemnified Party will give the indemnifying Party prompt written notice (an “Indemnification Claim Notice”) of any Losses or the discovery of any fact upon which the Indemnified Party intends to base a request for indemnification under Section 10.1 or Section 10.2, but in no event will the indemnifying Party be liable for any Losses to the extent such Losses result from any delay in providing such notice. Each Indemnification Claim Notice must contain a description of the claim and the nature and amount of such Loss (to the extent that the nature and amount of such Loss is known at such time). The Indemnified Party will furnish promptly to the indemnifying Party copies of all papers and official documents received in respect of any Losses and Third Party Claims.

Defense, Settlement, Cooperation and Expenses.

Control of Defense. At its option, the indemnifying Party may assume the defense of any Third Party Claim by giving written notice to the Indemnified Party within [***] after the indemnifying Party’s receipt of an Indemnification Claim Notice. The assumption of the defense of a Third Party Claim by the indemnifying Party will not be construed as an acknowledgment that the indemnifying Party is liable to indemnify the Indemnified Party in respect of the Third Party Claim, nor will it constitute a waiver by the indemnifying Party of any defenses it may assert against the Indemnified Party’s claim for indemnification. Upon assuming the defense of a Third Party Claim, the indemnifying Party may appoint as lead counsel in the defense of the Third Party Claim any legal counsel selected by the indemnifying Party. In the event the indemnifying Party assumes the defense of a Third Party Claim, the Indemnified Party will as soon as is reasonably possible deliver to the indemnifying Party all original notices and documents (including court papers) received by the Indemnified Party in connection with the Third Party Claim. Should the indemnifying Party assume the defense of a Third Party Claim, except as provided in this Section 10.4.1, the Indemnified Party will be responsible for the legal costs or expenses subsequently incurred by such Indemnified Party in connection with the analysis, defense or settlement of the Third Party Claim.

Right to Participate in Defense. Without limiting Section 10.4.1, any Indemnified Party will be entitled to participate in, but not control, the defense of such Third Party Claim and to employ counsel of its choice for such purpose; provided, however, that such employment will be at the Indemnified Party’s own cost and expense unless (a) the employment thereof has been specifically authorized by the indemnifying Party in writing, (b) the indemnifying Party has failed to assume the defense and employ counsel in accordance with Section 10.4.1 (in which case the Indemnified Party will control the defense), or (c) the interests of the Indemnified Party and the indemnifying Party with respect to such Third Party Claim are sufficiently adverse to prohibit the representation by the same counsel of both Parties under Applicable Law, ethical rules or equitable principles in which case the indemnifying Party will be responsible for any such costs and expenses of counsel for the Indemnified Party.

Settlement. With respect to any Third Party Claims relating solely to the payment of money damages in connection with a Third Party Claim and that will not admit liability or violation of Law on the part of the Indemnified Party or result in the Indemnified Party’s becoming subject to injunctive or other relief or otherwise adversely affecting the business of the Indemnified Party in any manner (such as granting a license or admitting the invalidity of a Patent Right Controlled by an Indemnified Party), and as to which the indemnifying Party will have acknowledged in writing the obligation to indemnify the Indemnified Party hereunder, the indemnifying Party will have the sole right to consent to the entry of any judgment, enter into any settlement or otherwise dispose of such Loss, on such terms as the indemnifying Party, in its sole discretion, will deem appropriate. With respect to all other Losses in connection with Third Party Claims, where the indemnifying Party has assumed the defense of the Third Party Claim in accordance with Section 10.4.1, the indemnifying Party will have authority to consent to the entry of any judgment, enter into any settlement or otherwise dispose of such Loss provided it obtains the prior written consent of the Indemnified Party (which consent will not be unreasonably withheld). The indemnifying Party will not be liable for any settlement, consent to entry of judgment, or other disposition of a Loss by an Indemnified Party that is reached without the written consent of the indemnifying Party. Regardless of whether the indemnifying Party chooses to defend or prosecute any Third Party Claim, no Indemnified Party will admit any liability with respect to or settle, compromise or discharge, any Third Party Claim without the prior written consent of the indemnifying Party, such consent not to be unreasonably withheld.

Cooperation. Regardless of whether the indemnifying Party chooses to defend or prosecute any Third Party Claim, the Indemnified Party will, and will cause each other Indemnified Party to, cooperate in the defense or prosecution thereof and will furnish such records, information and testimony, provide such witnesses and attend such conferences, discovery proceedings, hearings, trials and appeals as may be reasonably requested in connection therewith. Such cooperation will include access during normal business hours afforded to indemnifying Party to, and reasonable retention by the Indemnified Party of, records and information that are reasonably relevant to such Third Party Claim, and making Indemnified Parties and other employees and agents available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder, and the indemnifying Party will reimburse the Indemnified Party for all its reasonable out-of-pocket costs and expenses in connection therewith.

Costs and Expenses. Except as provided above in this Section 10.4, the costs and expenses, including attorneys’ fees and expenses, incurred by the Indemnified Party in connection with any claim will be reimbursed on a Calendar Quarter basis by the indemnifying Party, without prejudice to the indemnifying Party’s right to contest the Indemnified Party’s right to indemnification and subject to refund in the event the indemnifying Party is ultimately held not to be obligated to indemnify the Indemnified Party.

Insurance.

Fusion’s Insurance Obligations. Fusion will maintain, at its cost, reasonable insurance against liability and other risks associated with its activities contemplated by this Agreement, including but not limited to its indemnification obligations herein, in such amounts and on such terms as are customary for prudent practices for companies of similar size and with similar resources in the pharmaceutical industry for the activities to be conducted by it under this Agreement taking into account the scope of development of products. Fusion will furnish to AstraZeneca evidence of any insurance required under this Section 10.5.1, upon request.

AstraZeneca’s Insurance Obligations. AstraZeneca hereby represents and warrants to Fusion that it will maintain, at its cost, reasonable insurance against liability and other risks associated with its activities contemplated by this Agreement (including product liability), including but not limited to its indemnification obligations herein, in such amounts and on such terms as are customary for prudent practices for large companies in the pharmaceutical industry for the activities to be conducted by AstraZeneca under this Agreement. AstraZeneca will maintain such insurance or self-insurance throughout the Agreement Term and for [***] thereafter, and will furnish to Fusion evidence of such insurance, upon request.

LIMITATION OF CONSEQUENTIAL DAMAGES. EXCEPT FOR (a) CLAIMS OF A THIRD PARTY THAT ARE SUBJECT TO INDEMNIFICATION UNDER THIS ARTICLE 10, (b) CLAIMS ARISING OUT OF A PARTY’S WILLFUL MISCONDUCT, (c) A PARTY’S BREACH OF ARTICLE 5, OR (d) CLAIMS ARISING OUT OF A PARTY’S BREACH OF ITS CONFIDENTIALITY OBLIGATIONS UNDER THIS AGREEMENT, NEITHER PARTY NOR ANY OF ITS AFFILIATES WILL BE LIABLE UNDER THIS AGREEMENT TO THE OTHER PARTY TO THIS AGREEMENT OR ITS AFFILIATES FOR ANY INCIDENTAL, CONSEQUENTIAL, SPECIAL, PUNITIVE OR OTHER INDIRECT DAMAGES OR LOST OR IMPUTED PROFITS OR ROYALTIES, LOST DATA OR COST OF PROCUREMENT OF SUBSTITUTE GOODS OR SERVICES, WHETHER LIABILITY IS ASSERTED IN CONTRACT, TORT (INCLUDING NEGLIGENCE AND STRICT PRODUCT LIABILITY), INDEMNITY OR CONTRIBUTION, AND IRRESPECTIVE OF WHETHER THAT PARTY OR ANY REPRESENTATIVE OF THAT PARTY HAS BEEN ADVISED OF, OR OTHERWISE MIGHT HAVE ANTICIPATED THE POSSIBILITY OF, ANY SUCH LOSS OR DAMAGE.

Termination of the Agreement.

Termination for Lack of Commercial Viability.

Subject to Section 11.2.1(b), each Party will be entitled to terminate this Agreement on a Combination Collaboration Target -by- Combination Collaboration Target or Joint Radioconjugate-by-Joint Radioconjugate basis by providing [***] written notice to the other Party in the event of a Lack of Commercial Viability with respect to such Combination Collaboration Target or Joint Radioconjugate:

at any time after such Joint Radioconjugate is made a Joint Development Radioconjugate; and

at any time after such Combination Collaboration Target is made an Exclusive Combination Target;

provided, in each case (i) and (ii), that the Party that wishes to terminate is not in material breach or material default of its obligations under this Agreement in respect of such Combination Collaboration Target or Joint Radioconjugate.

Any termination pursuant to Section 11.2.1(a), shall be subject to the following:

If AstraZeneca or Fusion terminates a Joint Development Radioconjugate for Lack of Commercial Viability, then the non-terminating Party shall be given the option to continue the Development of the Joint Development Radioconjugate as a Single Party Radioconjugate, and the Parties shall enter into a commercially reasonable agreement, negotiated by the Parties in good faith, reflecting a revised schedule of milestone events, appropriate milestone payments and related financial aspects of such termination and continued Development and incorporating the licensing and technology transfer principles of Sections II and III of Appendix 4 hereto. If the non-terminating Party elects not to continue the Development of the Joint Development Radioconjugate as a Single Party Radioconjugate, then such Joint Development Radioconjugate shall terminate, along with: (1) any enabling licenses granted pursuant to Section 8.6.1 or Section 8.7.1 for relevant Fusion Background IP or AstraZeneca Background IP and (2) any supply obligations related to such Joint Development Radioconjugate. In the event either Party terminates a Joint Development Radioconjugate for Lack of Commercial Viability, any non-compete obligations related to such Joint Development Radioconjugate set forth in Section 5.2.1 shall terminate, regardless of whether the non-terminating Party chooses to continue the Development of the Joint Development Radioconjugate as a Single Party Radioconjugate.

Termination for Material Breach.

AstraZeneca’s Right to Terminate. If AstraZeneca has reason to believe that Fusion is in material breach of this Agreement, then AstraZeneca may deliver notice of such material breach to Fusion. If the breach is curable, Fusion will have [***] to cure such breach. If Fusion fails to cure such breach within the [***] period, or if the breach is not subject to cure, AstraZeneca may terminate this Agreement in its entirety if such breach relates to this Agreement in its entirety, or in relevant part on a Combination Collaboration Target by Combination Collaboration Target or Joint Radioconjugate-by-Joint Radioconjugate basis if such breach does not relate to this Agreement in its entirety, by providing written notice to Fusion.

The Parties further hereby irrevocably and unconditionally waive any objection to the laying of venue of any action, suit or proceeding (other than appeals therefrom) arising out of or relating to this Agreement in the courts of the State of Delaware, and hereby further irrevocably and unconditionally waive and agree not to plead or claim in any such court that any such action, suit or proceeding brought in any such court has been brought in an inconvenient forum. Each Party further agrees that service of any process, summons, notice or document by registered mail to its address set forth in herein shall be effective service of process for any action, suit or proceeding brought against it under this Agreement in any such court.

Court Actions. Nothing contained in this Agreement will deny either Party the right to seek injunctive or other equitable relief from a court of competent jurisdiction in the context of a bona fide emergency or prospective irreparable harm, and such an action may be filed and maintained notwithstanding any ongoing dispute resolution discussions.

Governing Law. The interpretation and construction of this Agreement shall be governed by the laws of the State of Delaware excluding any conflicts or choice of law rule or principle that might otherwise refer construction or interpretation of this Agreement to the substantive law of another jurisdiction.

Assignment and Successors. Neither this Agreement nor any obligation of a Party hereunder may be assigned by either Party without the consent of the other, which will not be unreasonably withheld, delayed or conditioned, except that each Party may assign this Agreement and the rights, obligations and interests of such Party, in whole or in part, without the other Party’s consent, to any of its Affiliates, to any purchaser of all or substantially all of its assets to which this Agreement or relevant part relates or to any successor of all or substantially all of its assets to which this Agreement relates resulting from any merger, consolidation, share exchange or other similar transaction; provided, if a Party transfers or assigns this Agreement (or any part hereof) to one of its Affiliates outside the United Kingdom, the United States, or Sweden that is incorporated (A) in a jurisdiction that does not have a Bilateral Income Tax Treaty with Canada, or (B) in a jurisdiction where a Bilateral Income Tax Treaty requires withholding taxes on any payment described in this Agreement, or otherwise takes any action that causes this Agreement or any payment made under this Agreement to become subject to tax in a jurisdiction outside of such Party’s country of organization or subject any payments made under this Agreement to withholding in any jurisdiction that would not have been required absent such action, then such Party (or such Affiliate) taking such action or making such transfer (“Transferring Party”), will (i) increase (i.e., “gross up”) any payment due that the Transferring Party is obligated to pay to the non-transferring Party (“Non-Transferring Party”) under ARTICLE 7 for the taxes withheld such that the Non-Transferring Party receives the amount the Non-Transferring Party would have otherwise received under ARTICLE 7 but for the Transferring Party’s transfer or assignment, and (ii) will provide written notice to the other Party within [***] after such assignment. Each Party shall remain responsible for compliance with its obligations under this Agreement after any permitted assignment by such Transferring Party hereunder. All validly assigned rights of a Party shall inure to the benefit of and be enforceable by, and all validly delegated obligations of such Party shall be binding on and be enforceable against, the permitted successors and assigns of such Party.

Force Majeure. No Party will be held responsible to the other Party nor be deemed to be in default under, or in breach of any provision of, this Agreement for failure or delay in performing any obligation of this Agreement when such failure or delay is due to force majeure, and without the fault or negligence of the Party so failing or delaying. For purposes of this Agreement, force majeure means a cause beyond the reasonable control of a Party, which may include acts of God; acts, regulations, or laws of any government; war; terrorism; civil commotion; fire, flood, earthquake, tornado, tsunami, explosion or storm; pandemic; epidemic and failure of public utilities or common carriers. In such event the Party so failing or delaying will immediately notify the other Party of such inability and of the period for which such inability is expected to continue. The Party giving such notice will be excused from such of its obligations under this Agreement as it is thereby disabled from performing for so long as it is so disabled for up to a maximum of [***], after which time the Parties will negotiate in good faith any modifications of the terms of this Agreement that may be necessary to arrive at an equitable solution, unless the Party giving such notice has set out a reasonable timeframe and plan to resolve the effects of such force majeure and executes such plan within such timeframe. To the extent possible, each Party will use reasonable efforts to minimize the duration of any force majeure. Notwithstanding anything to the contrary in the foregoing, for the purposes this Agreement, the COVID-19 pandemic ongoing as of the Effective Date, and any response thereto by a Governmental Authority or Regulatory Authority, shall not be considered a Force Majeure.

Notices. Any notice or request required or permitted to be given under or in connection with this Agreement will be deemed to have been sufficiently given if in writing and personally delivered or sent by facsimile transmission (receipt verified) or internationally recognized overnight express courier service (signature required), prepaid, to the Party for which such notice is intended, at the address set forth for such Party below:

Waiver. Neither Party may waive or release any of its rights or interests in this Agreement except in writing. The failure of either Party to assert a right hereunder or to insist upon compliance with any term or condition of this Agreement will not constitute a waiver of that right or excuse a similar subsequent failure to perform any such term or condition. No waiver by either Party of any condition or term in any one or more instances will be construed as a continuing waiver or subsequent waiver of such condition or term or of another condition or term.
