in the Acquired Assets until withdrawn in accordance with Section 8.5 (provided, that copies of such INDs shall be provided to Buyer as soon as reasonably possible, but in any event within [***], after the Closing
Date); provided, further, that following the date hereof, the Parties will discuss and agree upon reasonable security measures for transmitting any Personally Identifiable Information that is included in the Acquired Assets, and that
any compliance by Seller with such measures that results in the delivery of such data following such [***] period shall not be considered a breach of such obligation. All Acquired Assets shall be delivered to Buyer or its designated Affiliate at
[***] cost and expense. 
 2.2 Excluded Assets. Notwithstanding anything to the contrary in this Agreement, Seller shall not grant,
sell, transfer, convey, assign or deliver, and Buyer shall not, nor shall Buyer have any right to, purchase, accept or otherwise acquire, any right, title or interest in any of the following assets, properties, rights or interests of Seller or any

2.3 Assumed Liabilities. At the Closing, in accordance with and pursuant to the terms and conditions of this Agreement, Buyer shall
assume and agree to satisfy and discharge the following Liabilities (collectively, the “Assumed Liabilities”): 

  
 -20-

(b) all Liabilities to suppliers for materials and services to the extent related to the Business ordered prior to the Closing, but delivered
or provided thereafter, to the extent such orders are listed on Schedule 2.3(b) or are placed during the Pre-Closing Period in compliance with Section 6.1; 

(c) all Liabilities to make royalty, milestone or deferred payments or any other contingent payments under the 3BP License that become payable

(d) all Liabilities for (i) Transfer Taxes as described in Section 7.1 and (ii) Taxes (other than Transfer

or any of its Subsidiaries or Affiliates prior to or at the Closing. 
 2.4 Excluded Liabilities. Neither Buyer nor any of its
Affiliates shall assume, nor shall they be or become responsible for, any Liabilities of the Business or of Seller or of any of Seller’s Affiliates other than the Assumed Liabilities (collectively, the “Excluded Liabilities”).
Without limiting the generality of the foregoing, the following shall constitute the Excluded Liabilities notwithstanding any other provision of this Agreement:

 -21- 

 (f) all Liabilities arising out of any clinical trial with respect to any Product that was
commenced prior to the Closing, including all Liabilities arising out of the completion or termination of any clinical trial contemplated under Section 8.5. 

2.5 Procedures for Assignments. 

(a) Notwithstanding anything to the contrary contained herein, this Agreement shall not constitute an agreement to assign or transfer any
Acquired Asset (or right, benefit or obligation thereunder or resulting therefrom) if an assignment or transfer thereof, without the Consent of a Person, would constitute a breach or violation thereof and such Consent is not obtained at or prior to
the Closing. Seller shall use commercially reasonable efforts to obtain all such Consents prior to the Closing. If Seller is not successful in obtaining any such Consent at or prior to the Closing, then the Parties agree that, for [***], Seller will
use its commercially reasonable efforts [***], subject to Section 2.5(c), to obtain such Consent. Without limiting the representations and warranties of Seller set forth in Section 4.3 and
Section 4.9, the fact of a failure to obtain any such Consent shall not result in a breach of this Agreement in any manner. 

(b) If Seller is not successful in transferring or assigning any Acquired Asset or right, benefit or obligation thereunder or resulting
therefrom at the Closing in accordance with Section 2.5(a), then following the Closing and pending the receipt of such Consent, the Parties shall cooperate with each other in any mutually agreeable, reasonable and lawful
arrangements designed to provide Buyer with the benefits and burdens of any such Acquired Assets and any right, benefit or obligation thereunder or resulting therefrom as if the appropriate Consent had been obtained, including provision of the
consideration and other economic benefits to be received by Buyer in and under every Acquired Asset and right, benefit or obligation thereunder or resulting therefrom, which consideration shall be held for the benefit of, and shall be promptly
delivered to, Buyer. Once the applicable Consent for the assignment or transfer of any such Acquired Asset not assigned or transferred at the Closing is obtained, Seller shall assign and transfer such Acquired Asset to Buyer at no additional cost.
To the extent that any such Acquired Asset cannot be transferred or the full benefits and burdens of use of any such Acquired Asset cannot be provided to Buyer following the Closing pursuant to this Section 2.5, then Buyer
and Seller shall enter into such arrangements (including subleasing, sublicensing or subcontracting) to provide to the Parties the economic (taking into account Tax costs and benefits) and operational equivalent, to the extent permitted, of
obtaining such Consent (provided, that, with respect to any such asset that is a Contract, such obligation shall continue for only so long as the applicable Contract is in effect). Seller shall hold in trust for and pay to Buyer promptly upon
receipt thereof, all income, proceeds and other monies received by Seller or any of its Affiliates in connection with the use of any asset in connection with the arrangements under this Section 2.5. To the extent that Buyer
is provided the benefits and burdens of any Acquired Asset or right, benefit or obligation thereunder or resulting therefrom referred to herein (whether from Seller or otherwise) as if the appropriate Consent had been obtained, Buyer shall discharge
and perform the Liabilities of Seller thereunder or in connection therewith, as applicable, to the same extent as if the appropriate Consent had been obtained. 

  
 -22- 

 (c) Notwithstanding the foregoing in Sections 2.5(a) and 2.5(b), neither Party
nor any of its respective Affiliates shall have any obligation to (i) pay sums of money or provide any guarantee or other consideration, or agree to any undertaking, in connection with obtaining the Consents referred to in this
Section 2.5 or otherwise agree to any action that would adversely affect any Party or its Affiliates, or any Party’s or its Affiliates’ businesses or operations, or any right or obligation of such Party or any of
its Affiliates under any Contract related to such Consents, (ii) waive or discharge any Liabilities owing to either Party or its Affiliates by any counterparty under any such Contract, (iii) waive any rights of any Party or its Affiliates
under any such Contracts or (iv) amend, modify, supplement or otherwise change in any material respect (including any change that adversely affects pricing) the terms of any such Contract; provided, however, that nothing in this
Section 2.5(c) shall relieve Seller or any of its Affiliates of any of its obligations under any Acquired Asset for which a Consent is required to transfer to Buyer. 

2.6 Wrong Pocket Assets. 

(a) Subject to Section 2.5, if any Acquired Asset remains vested in Seller or any of its Affiliates following
Closing, Seller shall (or shall cause its applicable Affiliate to) transfer such Acquired Asset as soon as reasonably practicable to Buyer or its designee for no additional consideration. Seller shall notify Buyer as soon as reasonably practicable
upon becoming aware that that there are any Acquired Assets in its possession or control or that of any Affiliate of Seller. 
 (b) If any
Excluded Asset is vested in Buyer or any of its Affiliates following Closing, Buyer shall (or shall cause its applicable Affiliate to) transfer such Excluded Asset as soon as reasonably practicable to Seller or its designee for no consideration.
Buyer shall notify Seller as soon as reasonably practicable upon becoming aware that that there are any Excluded Assets in its possession or control. 

2.7 Purchase Price. 
 (a)
In consideration for the sale and transfer of the Acquired Assets, and subject to the terms and conditions of this Agreement, Buyer shall, in addition to the assumption of the Assumed Liabilities: 

(i) issue to Seller Four Hundred Thousand (400,000) Buyer Shares (subject, if applicable, to
Section 12.18); 
 (ii) pay to Seller an amount equal to the Inventory Value; 

(iii) subject to Section 2.8(a)(iii), upon the achievement of the Patent Event, issue to Seller the
Buyer Shares constituting the corresponding Deferred Fixed Payment in accordance with Section 2.8(a); 

(iv) upon the achievement of any Deferred Fixed Payment Event (other than the Patent Event), pay to Seller the corresponding
Deferred Fixed Payment in accordance with Section 2.8(a); and 
 (v) pay to Seller each Deferred
Variable Payment in accordance with Section 2.8(b). 

  
 -23- 

 The Closing Aggregate Share Value, the Inventory Value, the Patent Event Aggregate Share Value, and the
amounts described in the foregoing clauses (iv) and (v), in the aggregate, shall be referred to as the “Purchase Price”. Seller shall have the right, no later than [***] prior to the issuance or payment of any portion of
Purchase Price, to designate that such issuance or payment shall be made by Buyer directly to one of Seller’s Affiliates; provided, however, that Seller shall be responsible for any amount of Tax or any increase in the amount of
Tax payable with respect to any such payment resulting from such designation. 
 (b) No later than [***] prior to the Closing Date, Seller
shall deliver to Buyer a preliminary, non-binding statement setting forth, in reasonable detail, an itemized list of all Inventory together with Seller’s good faith estimate of the Inventory Value. No
later than [***] prior to the Closing Date, Seller shall deliver to Buyer a statement setting forth, in reasonable detail, an itemized list of all Inventory together with Seller’s good faith estimate of the Inventory Value, which amount shall
not exceed €737,828.80 (such estimate, the “Estimated Inventory Value”). 
 (c) Within [***] after the Closing
Date, Buyer shall cause to be prepared and delivered to Seller a statement (the “Closing Date Statement”) setting forth in reasonable detail its determination of the Inventory as of the Closing Date and the Inventory Value (the
“Closing Inventory Value”). If either Party conducts a physical inspection of the Inventory for the purpose of preparing the Closing Date Statement, such Party shall allow the other Party to have a Representative present for such
physical inspection. To the extent that any of the Inventory has not been transferred to the control of Buyer prior to the date such Closing Date Statement is due to be delivered by Buyer, Seller shall and shall cause its applicable Affiliates and
Third Party contractors to provide Buyer and its Representatives access to such Inventory solely for the purpose of preparing the Closing Date Statement. Notwithstanding anything to the contrary in this Section 2.7, the
Closing Inventory Value shall not exceed €737,828.80. 
 (d) Objections; Resolutions of Disputes. 

(i) Unless Seller notifies Buyer in writing within [***] after Buyer’s delivery of the Closing Date Statement (such [***] period, the
“Objection Period”) of any good faith objection to the Inventory or Closing Inventory Value set forth therein (a “Notice of Objection”), the Closing Date Statement shall be final and binding. Following the
delivery of the Closing Date Statement and solely for purposes of Seller’s review of the Closing Date Statement and preparation of any Notice of Objection or as reasonably requested by Seller in connection with the resolution of any disputes,
Buyer shall permit Seller and its Representatives to review the work papers of Buyer and its Representatives relating to the Closing Date Statement and will provide Seller and its Representatives with access to the Inventory. Any Notice of Objection
shall specify in reasonable detail each item that Seller disputes, the amount in dispute for each such dispute and a description in reasonable detail of the basis for the objections set forth therein. Seller and Buyer acknowledge that the sole
purpose of the determination of the Closing Inventory Value is to adjust the Purchase Price so as to reflect the difference between the Closing Inventory Value and the Estimated Inventory Value, and that in order to do so the Closing Inventory Value
and the Estimated Inventory Value need to be calculated in the same manner, without regard to any changes in IFRS that become effective following Seller’s calculation of the Estimated Inventory Value. 

  
 -24- 

 (ii) If Seller provides a Notice of Objection to Buyer within the Objection Period, Seller
and Buyer shall, during the [***] period following Buyer’s receipt of the Notice of Objection (such [***] period, as the same may be extended upon mutual agreement of the Parties, the “Resolution Period”), attempt in good faith
to resolve Seller’s objections. If Seller and Buyer reach an agreement with respect to any of Seller’s objections, the agreement(s) for any such resolved objections shall be reduced to writing and shall be final and binding on the Parties.
If Seller and Buyer are unable to resolve all such objections within the Resolution Period, the matters remaining in dispute shall be submitted to the Independent Accountant for resolution. If the Independent Accountant is required to be engaged
under this Section 2.7(d), the Independent Accountant shall be engaged pursuant to an engagement letter among Seller, Buyer and the Independent Accountant on terms and conditions consistent with this
Section 2.7(d). The Independent Accountant shall be instructed, pursuant to such engagement letter, to resolve only those matters that are set forth in the Notice of Objection and that remain in dispute at the time of its
engagement, and not to otherwise investigate any matter independently. Seller and Buyer shall instruct the Independent Accountant to render its reasoned written decision on such matters as promptly as practicable, but in no event later than [***]
from the date that the unresolved objections are submitted to the Independent Accountant for review. Seller and Buyer each agree to furnish to the Independent Accountant access to such individuals and such information, books and records as may be
reasonably required by the Independent Accountant to make its final determination (any such information, books and records shall be provided to the other Party prior to its submission or presentation to the Independent Accountant). Except as Seller
and Buyer may otherwise agree, all communications between Seller and Buyer or any of their respective Representatives, on the one hand, and the Independent Accountant, on the other hand, shall be in writing with copies concurrently delivered to the non-communicating Party. 
 (iii) With respect to each disputed item to be resolved by the Independent
Accountant under Section 2.7(d)(ii), the Independent Accountant’s decision, if not in accordance with the position of either Seller or Buyer, shall not be in excess of the higher, nor less than the lower, of the
amounts advocated by Seller in the Notice of Objection or Buyer in the Closing Date Statement with respect to such disputed item. The resolution of disputed items by the Independent Accountant shall be final and binding on the Parties (absent
manifest error). All fees and expenses of the Independent Accountant in respect of services pursuant to this Section 2.7(d), and of any enforcement of the determination thereby, shall be borne by Buyer and Seller in inverse
proportion to the difference between the Independent Accountant’s final determination and of the amounts advocated by Seller or Buyer with respect to such items, as applicable. The fees and expenses of Representatives of a Party incurred in
connection with the preparation or review of documentation provided to the Independent Accountant shall be borne by such Party. 
 (iv)
Within [***] after the date on which the Closing Date Statement (and the Closing Inventory Value contained therein) becomes final and binding on Seller and Buyer in accordance with Section 2.7, (A) if the Closing Inventory
Value is less than the Estimated Inventory Value, the Purchase Price shall be adjusted downward by the amount of such difference, and Seller shall pay the amount of such difference to Buyer and (B) if the Closing Inventory Value is greater than
the Estimated Inventory Value, the Purchase Price shall be adjusted upward by the amount of such excess, and Buyer shall pay the amount of such excess to Seller. Any payment under this Section 2.7(d)(iv) shall be made by
wire transfer of immediately available funds to an account designated in writing by the payee (such designation to be made at least [***] prior to the date on which such payment is due). 

  
 -25- 

 (v) Following the Closing and until the date the Closing Date Statement has become final
and binding pursuant to this Section 2.7(d), each Party shall (A) provide or cause to be provided to the other Party and its Representatives remote access upon reasonable notice during normal business hours to the
personnel and records of such Party and its Affiliates, and such Party’s, its Affiliates’ and its and their accountants’ work papers, in each case that are relevant to the preparation of the Closing Date Statement, any Notice of
Objection and the adjustments contemplated by this Section 2.7(d), and (B) cause its personnel to cooperate with the requesting Party and respond to such Party’s requests for information promptly with respect
thereto. Neither Party’s accountants shall be obligated to make any work papers available to any Person under this Section 2.7(d)(v) unless and until such Person has signed a customary confidentiality and hold harmless
agreement relating to such access to work papers in form and substance reasonably acceptable to such accountants. 
 2.8 Deferred
Payments. 
 (a) Deferred Fixed Payments. 

(i) Deferred Fixed Payments. Subject to the terms of this Section 2.8, upon the first
occurrence of each of the following events (each, a “Deferred Fixed Payment Event”), Buyer shall (A) pay to Seller the corresponding amount or (B) in the case of the Patent Event, issue to Seller the corresponding Buyer
Shares in accordance with the Share Purchase Agreement (each, a “Deferred Fixed Payment”): 
  

					
	 Development and Regulatory Events

	  	 Deferred Fixed Payment

	 (6)
	  	Achievement of Annual Net Sales of greater than €[***]	  	€[***]
	 (7)
	  	Achievement of Annual Net Sales of greater than €[***]	  	€[***]
	 (8)
	  	Achievement of Annual Net Sales of greater than €[***]	  	€[***]
	 (9)
	  	Achievement of Annual Net Sales of greater than €[***]	  	€[***]

 Each of the foregoing Deferred Fixed Payments shall be payable a maximum of one (1) time as set forth in the foregoing
charts regardless of (A) the number of Products achieving the applicable Deferred Fixed Payment Event or (B) the number of indications for which a Product achieves the applicable Deferred Fixed Payment Event, and no Deferred Fixed Payments
shall be due hereunder for subsequent or repeated achievement of such Deferred Fixed Payment Events. The Deferred Fixed Payments corresponding to the Sales Events are additive, such that if more than one Sales Event is achieved in the same calendar
year, then each corresponding Deferred Fixed Payment will be payable. The maximum Deferred Fixed Payment for the Development and Regulatory Events is Sixty Seven Million Five Hundred Thousand Euros (€67,500,000). The maximum Deferred Fixed
Payment for the Patent Event is two hundred thousand (200,000) Buyer Shares (subject, if applicable, to Section 12.18). The maximum Deferred Fixed Payment for the Sales Events is Three Hundred Fifty Million Euros
(€350,000,000). The maximum Deferred Fixed Payments in the aggregate is Four Hundred Seventeen Million Five Hundred Thousand Euros (€417,500,000) plus two hundred thousand (200,000) Buyer Shares (subject, if applicable, to
Section 12.18). 
 (ii) Skipped Deferred Fixed Payment Events. With respect to the
Development and Regulatory Events: (a) if for any reason Deferred Fixed Payment Event (1) does not occur before the first to occur of Deferred Fixed Payment Event (2) or any First Commercial Sale Event, then Deferred Fixed Payment
Event (1) will be deemed to occur concurrently with the first to occur of Deferred Fixed Payment Event (2) or any First Commercial Sale Event and (b) if for any reason Deferred Fixed Payment Event (2) does not occur before any
First Commercial Sale Event is achieved, then Deferred Fixed Payment Event (2) will be deemed to occur concurrently with the first First Commercial Sale Event to occur. 

(iii) Patent Event Early Achievement. In the event that the Patent Event is achieved prior to the Closing Date, the
Deferred Fixed Payment corresponding to the Patent Event shall be issued to Seller at Closing. 

  
 -27- 

 (b) Deferred Variable Payments. Subject to the terms of this
Section 2.8, Buyer shall make payments (each such payment, a “Deferred Variable Payment”) to Seller based on a percentage of Annual Net Sales of Products in the Territory during the Deferred Variable
Payment Terms, which Deferred Variable Payments shall be equal to the percentage rate set forth as follows: 
  

			
	 Annual Net Sales
	  	Rate
	 For that portion of Annual Net Sales less than or equal to €[***]
	  	[***]%
	 For that portion of Annual Net Sales greater than €[***] and less than or equal to
€[***]
	  	[***]%
	 For that portion of Annual Net Sales greater than €[***]
	  	[***]%

 For illustrative purposes only and not in limitation of anything set forth in this Section 2.8, a
sample calculation of Deferred Variable Payments is set forth on Exhibit B. 
 (c) Deferred Variable Payment Rate Reductions.

 (i) Notwithstanding Section 2.8(b): 

(A) from and after the end of the first calendar quarter in which a Product is sold in a country in the Territory and [***],
the rate for such Product set forth in Section 2.8(b) with respect to such country shall be reduced by [***] percent ([***]%); 

(B) from and after the end of the first calendar quarter in which a Product is sold in a country in the Territory and [***],
the rate for such Product set forth in Section 2.8(b) with respect to such country shall be reduced by [***] percent ([***]%); provided, for the avoidance of doubt, that if at such time the reduction described in
Section 2.8(c)(i)(A) shall have gone into effect with respect to such Product in such country, the total reduction as a result of Section 2.8(c)(i)(A) and this
Section 2.8(c)(i)(B) shall be [***] percent ([***]%); 
 (C) if in any country in the Territory
during the Deferred Variable Payment Term in such country for a Product, Loss of Exclusivity occurs with respect to such Product in such country, then from and after the end of the calendar quarter in which such Loss of Exclusivity first occurs, the
Deferred Variable Payments due to Seller pursuant to Section 2.8(b) with respect to such Product in such country shall be reduced by [***] percent ([***]%) thereafter; 

(D) if in any country in the Territory during the Deferred Variable Payment Term in such country for a Product, [***]; and 

(E) if any Payment Obligor enters into an agreement with a Third Party in order to obtain a license or other right to a Valid
Claim of Patent Rights that is necessary to make, use or sell a Compound or Product in any country in the Territory in order to avoid infringing Third Party Patent Rights, Buyer shall be entitled to deduct from any Deferred Variable Payments payable
under Section 2.8(b) with respect to such Product in such country [***] percent ([***]%) of [***] amounts paid to such Third Party in respect of such agreement, in each case, to the extent reasonably allocable to such
Product and Patent Rights in such country (“Third Party Payments”). Notwithstanding the foregoing, in no event shall Third Party Payments made in connection with a license or other rights to Patent Rights obtained specifically in
connection with a change in the radioisotope in a given Compound be eligible to reduce Deferred Variable Payments under this Section 2.8(c)(i)(E). 

  
 -28- 

 (ii) Notwithstanding any other provision of this Agreement, in no event shall the
reductions made pursuant to Section 2.8(c)(i) with respect to any Product in any country reduce by more than [***] percent ([***]%) the Deferred Variable Payments that would otherwise be owed by Buyer under
Section 2.8(b) with respect to such Product in such country in any calendar quarter. [***]. 
 (d) Payment
Terms. 
 (i) Currency and Conversion. Subject to the following sentence, all payments under this Agreement shall
be in Euros (€). Whenever calculations of Net Sales or Deferred Variable Payments require conversion from any currency into Euros, Buyer shall convert into Euros, using the exchange rate corresponding to the average, over the applicable period
to which such Net Sales or Deferred Variable Payments relate, of the daily European Central Bank foreign exchange reference rate of the Euro against the currency of the country in which the applicable Net Sales were made. 

(ii) Deferred Fixed Payments. 

(A) Promptly following the first achievement of any Development and Regulatory Event, but in no event later than [***] days
thereafter, Buyer shall inform Seller of the achievement of such Development and Regulatory Event and Buyer shall pay to Seller, by wire transfer of immediately available funds in accordance with written instructions provided by Seller, the
corresponding Deferred Fixed Payment. 
 (B) Promptly following the first achievement of any Sales Event, but in no event
later than [***] days thereafter, Buyer shall inform Seller of the achievement of such Sales Event and Buyer shall pay to Seller, by wire transfer of immediately available funds in accordance with written instructions provided by Seller, the
corresponding Deferred Fixed Payment. 
 (iii) Deferred Variable Payments and Reporting. After the First Commercial
Sale of a Product in the Territory, Buyer shall calculate Deferred Variable Payments quarterly at the end of each calendar quarter and shall pay to Seller, by wire transfer of immediately available funds in accordance with written instructions
provided by Seller, Deferred Variable Payments on Annual Net Sales achieved during such calendar quarter within [***] days after the end of each of the first three calendar quarters of the year and within [***] days after the end of the fourth
calendar quarter of the year. With each such payment, Buyer shall provide in writing to Seller for the relevant calendar quarter the following information on a
country-by-country and Product-by-Product basis (all of which shall constitute Buyer
Information): 

  
 -29- 

 (A) the amount of Product sold, the Net Sales (expressed in Euros where
gross sales are invoiced in Euros and, for gross sales invoiced in any other non-Euro currency, the applicable conversion rates and the resulting amount in Euros, in accordance with the provisions of
Section 2.8(d)(i)) on a Product-by-Product basis, in value; and 

(B) the total Deferred Variable Payments payable (expressed in Euros, in accordance with the provisions of
Section 2.8(b)) on a Product-by-Product basis. 

(iv) Late Payments. Any payment under this Agreement that is not timely paid shall bear interest, to the extent
permitted by applicable Law, at the lesser of: (A) [***] percentage points above the prime rate of interest of the European Central Bank as announced on the date such payment is due (provided, that if such prime rate is negative, the rate in
this clause (A) shall be [***]%), and (B) the highest rate permitted under applicable Law, which payments shall be calculated on the number of days such a payment is overdue starting on the first day of the payment being overdue,
compounded monthly. Except as set forth in the immediately preceding sentence, no interest shall accrue or be paid on any portion of any Deferred Fixed Payment or Deferred Variable Payment. 

(v) Accounting and Audit. Buyer and its Affiliates shall, and shall cause all other Payment Obligors to, maintain full,
true and accurate books of account containing all particulars that may be necessary for the purpose of calculating all Deferred Variable Payments payable under this Agreement and verifying all other payments to be made pursuant to this Agreement.
Buyer and its Affiliates shall, and shall cause all other Payment Obligors to, permit Seller, by independent accountants selected by Seller and reasonably acceptable to Buyer, to examine such books and records at any reasonable time, but not later
than [***] following the rendering of any corresponding reports, accountings and payments pursuant to this Agreement. The foregoing right of audit may be exercised only once during any [***] period, except in the event that a previous audit during
such [***] period detected any material inaccuracies in payments, in which case, Seller may exercise its right of audit once more during such [***] to confirm that such inaccuracies have been corrected. The auditing accountants shall be required by
Buyer or its Affiliates to enter into a reasonably acceptable confidentiality agreement, and in no event shall such accountants disclose to Seller or its Affiliates any information other than such as relates to the accuracy of reports and payments
made or due hereunder. The opinion of said independent accountants regarding such reports, accountings and payments shall be binding on the Parties. Seller shall bear the cost of any such audit; provided, that if the audit shows an
underpayment due by Buyer to Seller of more than [***] percent ([***]%) of the amount due, then Buyer shall promptly reimburse Seller for the costs of accountants incurred in connection with such audit. If the audit concludes that
(A) additional amounts are owed by Buyer, Buyer shall promptly pay to Seller the amount of any such underpayment revealed by such audit, together with the costs of the accountants, as applicable; or (B) excess payments were made by Buyer,
Buyer shall be entitled to set-off against and deduct the amount of any such excess payment from any Deferred Fixed Payment or Deferred Variable Payment that is then due and payable hereunder, or which becomes
due and payable hereunder within [***] following such conclusion, or if no Deferred Fixed Payments or Deferred Variable Payments become due and payable hereunder within [***] following such conclusion, Seller shall promptly reimburse Buyer for such
excess payments. 

  
 -30- 

 (vi) [***]. 

(e) Other Terms.

Fixed Payment Events (1) through (4) and to market, promote, sell and distribute at least one (1) Product in [***]. This obligation shall expire, and this Section 2.8(e)(i) shall have no further force and effect,
upon the achievement of the last Deferred Fixed Payment Event. Seller acknowledges and agrees that the conversion, by Buyer, of one or more Products to an alpha isotope and any delay caused by such conversion shall not, in and of itself, constitute
a failure to use Commercially Reasonable Efforts. Seller acknowledges and agrees that the Development and Regulatory Events, Sales Events and sales levels set forth under Section 2.8(b), shall not be construed as
representing an estimate or projection of anticipated results or sales of the Products, or implying any level of diligence or Commercially Reasonable Efforts and that the Development and Regulatory Events, Sales Events and such sales levels are
merely intended to define Buyer’s deferred payment obligations in the event that such events or sales levels are achieved. 

(ii) Reporting. 

(A) Development Reports. On July 31 of each calendar year until the filing of Regulatory Approval at the FDA and
the EMA and thereafter once annually by January 30 of each calendar year, Buyer will provide to Seller a written progress report that will describe the development activities that Buyer or its Affiliates (including any Payment Obligors) have
performed or caused to be performed during the preceding twelve (12) month period and that are intended to be performed during the following twelve (12) month period. Such reports shall include any regulatory activities, including
preparation and design of clinical studies, filing of INDs and other clinical trial applications, preparation and design of MAAs, conduct and progress of Regulatory Approval processes, including meeting minutes and other material correspondence with
the FDA and any comparable Regulatory Authorities outside of the U.S., and pricing and reimbursement strategies and activities regarding the establishment of manufacture processes (including radiolabeling) and obtaining manufacturing licenses or
other manufacturing permits. The reporting shall be made on a Product-by-Product basis and, as regards regulatory activities, in addition, on a country-by-country basis. The reporting shall include demonstration of whether a Compound or Product is developed for therapeutic or diagnostic use. Within three
(3) months from the receipt of each report, Seller shall be entitled to request from Buyer a meeting (by

means of video or telephone conference or similar method through which all participants in the meeting can hear each other) to discuss the last-received report and such meeting shall [***] take
place within thirty (30) days following such request. Buyer shall make available for such meeting sufficiently experienced and qualified personnel of Buyer to discuss such report. Each Party shall bear its costs arising in connection with such
meeting. All reports made under this Section 2.8(e)(ii)(A) shall be deemed Buyer Information. After the occurrence of the First Commercial Sale of a Product, Buyer shall no longer have an obligation to submit any annual
development report under this Section 2.8(e)(ii)(A) in relation to such Product, unless there are ongoing development activities for such Product for any other indication than that for which the First Commercial Sale
occurred, in which event the obligation to submit annual development reports pursuant to this Section 2.8(e)(ii)(A) continues until termination of all development activities with respect to such Product. 

(B) Commercialization Reports. On March 31 of each calendar year after the First Commercial Sale of a Product,
Buyer will provide to Seller a written progress report that will describe the commercialization activities that all Payment Obligors have performed or caused to be performed during the preceding calendar year and which all Payment Obligors intend to
perform during the following calendar year for such Product. The reporting shall be made on a Product-by-Product basis and country-by-country basis. The reports shall include any commercialization activities, marketing and promotion activities, reimbursement and pricing activities and any pharmacovigilance events and reporting.
All reports made under this Section 2.8(e)(ii)(B) shall be deemed Buyer Information.

clinical study of any Compound or Product conducted by or on behalf of Seller or its Affiliates during such period for inclusion by Buyer in the report covering such period to be submitted under Section 5.3 of the 3BP License. Following the
Closing, for so long as any clinical study of any Compound or Product is conducted by or on behalf of Seller or its Affiliates until such time as the clinical study report for each such study, if any, has been completed and provided to Buyer or such
study has been terminated and Seller has provided a final report under this Section 2.8(e)(ii)(C) with respect to such study, Seller shall provide to Buyer, within ten (10) days following the end of the applicable
reporting period under Section 5.3 of the 3BP License, a description of the activities undertaken in connection with any such clinical study during the applicable reporting period for inclusion by Buyer in the report to be submitted under
Section 5.3 of the 3BP License. The information to be provided by Seller under this Section 2.8(e)(ii)(C) shall, to the extent possible, be in a format consistent with the development reports submitted by Seller or its

shall use commercially reasonable efforts to cause all other Payment Obligors not to, engage in any transaction or a series of transactions (including by merger or consolidation or otherwise by operation of law), but excluding any transaction or
series of transactions that would result in a Change of Control of Buyer, that would result in the sale, conveyance, transfer or other disposition of all or substantially all of Buyer’s and its Affiliates’ rights covering any Product to a
Third Party, unless, and as a condition thereto, the transferee or successor assumes and succeeds to all of the obligations of Buyer set forth in Section 2.8 and prior to or simultaneously with the closing of such
transaction delivers to Seller an instrument of assumption for the benefit of Seller and its Affiliates, and in form reasonably acceptable to Seller, effecting such assumption and succession. Any such Product Transfer will not release Buyer from its
obligations under Section 2.8.

information provided by Buyer under this Section 2.8 in violation of such Laws.

are being granted, executed and delivered to maintain or preserve the fair market value of the Acquired Assets, and (b) that no proceeds or other amount received or receivable under this Agreement by Seller shall be for granting any Restrictive

request) and within the prescribed time limits pursuant to subsection 56.4(7) of the ITA, and any analogous provision of Canadian provincial or territorial Tax Laws.

of Seller, on the other hand (nor, for the avoidance of doubt, shall Buyer or Seller or any of their respective Affiliates have any right to use any document or information obtained from the other pursuant to this

 11.4 Third Party Claims. 

(a) In the event that any claim or demand for which Buyer or Seller (an “Indemnifying Party”) may have Liability to any
Indemnified Party hereunder is asserted against or sought to be collected from any Indemnified Party by a Third Party (a “Third Party Claim”), Buyer (on behalf of any Buyer Indemnified Party) or Seller (on behalf of any Seller
Indemnified Party), as applicable, shall promptly, but in no event more than [***] following such Indemnified Party’s receipt of a Third Party Claim (it being specified that if the Third Party Claim is made by a Taxing Authority and relates to
Taxes, the relevant notice period shall be [***]), notify the Indemnifying Party in writing of such Third Party Claim, the specific section(s) of this Agreement that form the basis of the claim for indemnification, the amount or the estimated amount
of damages sought under such Third Party Claim to the extent then ascertainable (which amount shall not be conclusive of the final amount of such claim), any other remedy sought thereunder, any relevant time constraints relating thereto and, to the
extent practicable, any other material details pertaining thereto (a “Claim Notice”); provided, however, that the failure to timely give a Claim Notice shall affect the rights of an Indemnified Party hereunder only to
the extent that such failure has a materially prejudicial effect on the defenses or other rights available to the Indemnifying Party with respect to such Third Party Claim. 

(b) The Indemnifying Party shall have the right to defend the Indemnified Party in connection with any Third Party Claim and shall have the
sole power to direct and control such defense with counsel selected by the Indemnifying Party and reasonably acceptable to the Indemnified Party provided, however, that the Indemnifying Party may not assume control of the
defense of any Third Party Claim (i) involving criminal liability or in which relief other than monetary damages is sought or (ii) involving a purported class action. If the Indemnifying Party elects to defend the Indemnified Party against
a Third Party Claim, it shall within [***] after its receipt of the applicable Claim Notice (or sooner, if the nature of the Third Party Claim so requires) notify the Indemnified Party of its intent to do so. Once the Indemnifying Party has assumed
the defense of a Third Party Claim, the Indemnified Party shall have the right, but not the obligation, to participate in any such defense and to employ separate counsel of its choosing at its own cost and expense; provided, however,
that such Indemnified Party shall be entitled to participate in any such defense with separate counsel at the expense of the Indemnifying Party if so requested by the Indemnifying Party to participate. The Indemnifying Party shall not, without the
prior written consent of Buyer (on behalf of any Buyer Indemnified Party) or Seller (on behalf of any Seller Indemnified Party), as applicable (such consent not to be unreasonably withheld, conditioned, or delayed in the case of the following clause
(B)), settle, compromise or offer to settle or compromise any Third Party Claim (A) if the Indemnifying Party has not notified the Indemnified Party in writing that it will be liable to indemnify the Indemnified Party with respect to all Losses
relating to such Third Party Claim, subject to the limitations of Section 12.2 or Section 12.3, as applicable, or (B) on a basis that would result in (x) the imposition of a consent
order, injunction, decree or other Order, or the entry into any Contract, that would restrict the future activity or conduct of the Indemnified Party or any of its Affiliates, or (y) a finding or admission of a violation of Law, violation of
the rights of any Person or other wrongdoing by the Indemnified Party or any of its Affiliates. 

  
 -66- 

 (c) If the Indemnifying Party elects not to defend the Indemnified Party against a Third
Party Claim, or is not permitted to assume the defense of a Third Party Claim pursuant to Section 11.4(b), the Indemnified Party shall have the right but not the obligation to assume its own defense, it being understood
that any right of the Indemnified Party to indemnification for a Third Party Claim shall not be adversely affected by assuming the defense of such Third Party Claim. The Indemnifying Party shall have no Liability with respect to a Third Party Claim
settled without its consent, which consent shall not be unreasonably withheld, conditioned or delayed. 
 (d) The Indemnified Party and the
Indemnifying Party shall reasonably cooperate in order to ensure the proper and adequate defense of a Third Party Claim. The Indemnified Party and the Indemnifying Party shall keep each other fully informed with respect to the status of such Third
Party Claim. 
 (e) The Indemnified Party and the Indemnifying Party shall use commercially reasonable efforts to avoid production of
confidential information (consistent with applicable Law), and to cause all communications among employees, counsel and others representing any party to a Third Party Claim to be made so as to preserve any applicable attorney-client or work-product
privileges. 
 11.5 Direct Claims. 

(a) If an Indemnified Party wishes to make a claim for indemnification hereunder for a Loss that does not result from a Third Party Claim (a
“Direct Claim”), Buyer (on behalf of any Buyer Indemnified Party) or Seller (on behalf of any Seller Indemnified Party), as applicable, shall notify the Indemnifying Party in writing of such Direct Claim, the specific section(s) of
this Agreement that form the basis of the claim for indemnification, the amount or the estimated amount of damages sought with respect to such Direct Claim to the extent then ascertainable (which amount shall not be conclusive of the final amount of
such claim), any other remedy sought thereunder, any relevant time constraints relating thereto and, to the extent practicable, any other material details pertaining thereto; provided, however, that the failure to give such a claim
notice shall affect the rights of an Indemnified Party hereunder only to the extent that such failure has a materially prejudicial effect on the defenses or other rights available to the Indemnifying Party with respect to such claim. 

(b) The Indemnifying Party shall have a period of [***] within which to respond to such Direct Claim. If the Indemnifying Party does not
respond within such [***] period, the Indemnifying Party will be deemed to have accepted the Direct Claim. If the Indemnifying Party rejects all or any part of the Direct Claim, the Indemnified Party shall be free to seek enforcement of its rights
to indemnification under this Agreement with respect to such Direct Claim. 
 11.6 [***]. [***].

 11.7 Adjustment to Losses. 

(a) Insurance. In calculating the amount of any Loss, the proceeds actually received by the Indemnified Party or any of its Affiliates
under any insurance policy or pursuant to any claim, recovery, settlement or payment by or against any other Person (less the sum of (i) reasonable out-of-pocket costs
and expenses relating to collection of such proceeds, (ii) any incremental increase in premiums directly resulting therefrom, and (iii) any deductible or retention associated therewith), in each case relating to a Third Party Claim or a
Direct Claim, shall be deducted. 
 (b) Taxes. In calculating the amount of any Loss, such Loss shall be reduced by the amount of any
Tax savings or benefits [***] from or arising out of such Loss. 
 (c) Reimbursement. If an Indemnified Party recovers an amount from
a Third Party in respect of a Loss that is the subject of indemnification hereunder after all or a portion of such Loss has been paid by an Indemnifying Party pursuant to this Article XI, the Indemnified Party shall promptly remit to the
Indemnifying Party the excess (if any) of (i) the amount paid by the Indemnifying Party in respect of such Loss, plus (ii) the amount received from the Third Party in respect thereof (less the reasonable out-of-pocket costs and expenses incurred in connection with such recovery), less (iii) the full amount of the Loss. 

(d) Other Recovery. The provisions of this Article XI are not intended to permit duplicate recoveries on the same matters. 

11.8 Characterization of Indemnification Payments. Except as otherwise required by applicable Law, all payments made by an Indemnifying
Party to an Indemnified Party in respect of any claim pursuant to Section 11.2 or Section 11.3 shall be treated as adjustments to the Purchase Price for all applicable Tax purposes. 

11.9 Exclusive Remedy. Subject to Sections 2.7(d) and 12.11, the Parties acknowledge that their sole and exclusive
monetary remedy after the Closing with respect to any claims relating to, arising under, or resulting from this Agreement, and the sole and exclusive monetary remedy available to any Buyer Indemnified Party or Seller Indemnified Party after the
Closing with respect to any claims relating to, arising under, or resulting from this Agreement, shall be pursuant to the indemnification provisions set forth in this Article XI. Subject to Section 12.11, in
furtherance of the foregoing, each Party hereby waives, from and after the Closing, to the fullest extent permitted under applicable Law, any rights, claims, and causes of action for Losses it may have against the other Party arising under this
Agreement or any certificate delivered in connection herewith, except pursuant to the indemnification provisions set forth in this Article XI. The foregoing shall in no way limit the remedies available to (a) any Party in the case of
Fraud or (b) any Person under any Ancillary Agreement. 
 11.10 Duty to Mitigate. Nothing herein shall relieve any Indemnified
Party of any common law duty to mitigate Losses. 
 11.11 Satisfaction of Indemnification Claims. 

(a) [***]. 
 (b) Subject to the
rights of Seller set forth in Section 11.11(a) and the rights of Buyer set forth in Section 11.6, Buyer or Seller, as applicable, shall pay the amount of any indemnification claim for which it
agrees it is liable, or that has been finally determined to be owing by a court of competent jurisdiction or an arbitral body, in each case in accordance with this Agreement, and which has not otherwise been satisfied in accordance with this
Agreement, by wire transfer of funds within [***] after such agreement or determination.

 ARTICLE XII 

MISCELLANEOUS 
 12.1
Assignment. 
 (a) Except as expressly permitted herein (including pursuant to Section 1.3 and
Section 12.1(b)), this Agreement may not be assigned or transferred by either Party in whole or in part, nor may any Party assign or transfer any rights or obligations created by this Agreement, in each case, whether by
operation of Law, assignment, succession or otherwise, without the prior written consent of the other Party, which consent will not be unreasonably withheld, conditioned or delayed. 

(b) Notwithstanding the limitations in Section 12.1(a), either Party may assign or transfer this Agreement, or any
rights or obligations hereunder in whole or in part, to (i) one (1) or more of its Affiliates or (ii) its successor in interest in connection with the merger, consolidation, or sale of all or substantially all of its assets or all or
substantially all of that portion of its business pertaining to the subject matter of this Agreement (provided, however, that (A) such Party will remain fully and unconditionally liable and responsible to the other Party for the
performance and observance of all such duties and obligations by such Affiliate or successor, and (B) if any such assignment leads to or increases the amount of any withholding Taxes incurred by the
non-assigning Party with respect to the Transactions, then the amount of such Tax or such increased Tax shall be borne by the assigning Party and any amount payable by the assigning Party to the other Party
shall be increased to take into account such excess withholding Taxes as may be necessary so that, after making all required withholdings, the other Party receives the same amount that it would have received had no such excess withholding been
required; provided, further, that such increased amount payable to the other Party under this Section 12.1(b) shall be net of any withholding tax credits available to the other Party to offset any other
liability for Taxes). 
 (c) The terms of this Agreement will be binding upon and will inure to the benefit of the successors, heirs,
administrators and permitted assigns of the applicable Party. Any purported assignment in violation of this Section 12.1 will be null and void ab initio. 

12.2 Public Announcements. Neither Party nor any of their respective Affiliates shall issue any press release or make any public
announcement relating to the subject matter of this Agreement without the prior written consent of the other Party, which consent shall not be unreasonably withheld, delayed or conditioned; provided, however, that any Party and any of
their respective Affiliates may make any public disclosure (a) it believes in good faith, upon advice of counsel, is required by applicable Law or any listing or trading agreement concerning its publicly traded securities (in which case the
disclosing Party or Affiliate will provide reasonable advance notice, to the extent reasonably practicable, to the other Party prior to making the disclosure and will in good faith consider the reasonable comments of the other Party on such
disclosure) or (b) that is substantially consistent with a prior press release or public announcement made with the consent of the other Party. 

  
 -69- 

 12.3 Confidentiality. 

(a) Buyer and Seller agree that the Confidentiality Agreement, as it relates to Information, shall, as of the Closing Date, be terminated and
of no further force and effect. 
 (b) Seller agrees that, from the Closing Date until the date that is five (5) years following the
Closing Date (or, with respect to any Buyer Information delivered to Seller in accordance with Section 2.8, the date that is five (5) years following the date of such delivery) or with respect to any Buyer Information
that constitutes a trade secret under applicable Law, until the later of the date that is five (5) years following the Closing Date and the date on which such Buyer Information no longer constitutes a trade secret under applicable Law (other
than as a result of any disclosure in violation of the Confidentiality Agreement, this Agreement or any Ancillary Agreement), Seller, any of its applicable Affiliates, and their Representatives (i) shall not use any Buyer Information for any
purpose other than as required to perform their respective obligations or exercise or enforce their respective rights and remedies under this Agreement or any Ancillary Agreement or as required to comply with their respective regulatory, stock
exchange, Tax, accounting or financial reporting requirements, and shall (ii) keep confidential and exercise the same degree of care with respect to maintaining the confidentiality of any Buyer Information in any of their possession that Seller
and its Affiliates exercise with respect to similar types of their own proprietary information, but in no event less than a reasonable degree of care, except that if any Buyer Information is required by Law or legal or administrative process to be
disclosed, Seller shall promptly (and in any event prior to making such disclosure, to the extent permitted by Law) notify Buyer of such disclosure requirement so that Buyer or its Affiliates may seek a protective Order or other appropriate remedy;
provided, that notwithstanding the foregoing, Seller, its Affiliates and their Representatives may use and disclose (subject to reasonable and customary confidentiality obligations having a term at least commensurate with the term of
Seller’s obligations under this Section 12.3(b)) Buyer Information in connection with the activities described in and permitted by Section 8.10. Seller shall, shall cause its Affiliates to and
shall direct its respective Representatives to, reasonably cooperate, at Buyer’s expense, with Buyer or its Affiliates’ efforts to obtain such protective Order or other appropriate remedy. In the event that no such protective Order or
other remedy is obtained, or Buyer does not waive compliance with this Section 12.3(b), and any of Seller, its applicable Affiliates, or their Representatives are nonetheless legally compelled to disclose such Buyer
Information, then Seller, such Affiliate or such Representative, as the case may be, will furnish only that portion of the Buyer Information which Seller, such Affiliate or such Representative is advised by counsel is legally required to be
furnished and will give Buyer written notice of the Buyer Information to be disclosed as far in advance as reasonably practicable and exercise all reasonable efforts to obtain reliable assurance that confidential treatment will be accorded the Buyer
Information. For purposes of this Section 12.3(b), the term “Buyer Information” means (i) all information, knowledge and data of Seller and its Affiliates as of immediately prior to the Closing
to the extent related to the Business, the Acquired Assets, any Compound or Product or the Assumed Liabilities, (ii) all information, knowledge and data provided by Buyer or any of its Affiliates to Seller in connection with the Transactions
other than any information contemplated by clause (i), but including all information provided by Buyer under Section 2.8, and (iii) all analyses, compilations, forecasts, studies, interpretations, summaries, notes,
data and other documents and materials (in any form or medium of communication, whether written, oral, electronic or magnetic), whether prepared by Seller, any of its applicable Affiliates, any of their Representatives, or others, which contain,
reflect or are 

  
 -70- 

 
generated from or based upon, in whole or in part, the information referred to in clauses (i) and (ii) of this sentence, other than any such information that (A) only with respect to
(ii) above, is known to Seller prior to receipt thereof from Buyer or any of its Affiliates, (B) is disclosed to Seller by a Third Party which has, or is reasonably believed by Seller to have, a legal right to make such disclosure without
requiring Seller to maintain the confidentiality thereof, (C) is or becomes part of the public domain through no fault of Seller, or (D) is independently developed by or for Seller, without reliance on or reference to any information
contemplated by clauses (i) or (ii) of this sentence. 
 (c) Buyer agrees that, from the Closing Date until the date that is five
(5) years following the Closing Date, Buyer and its Representatives shall not use any Seller Information for any purpose other than as required to (i) perform their respective obligations or exercise or enforce their respective rights and
remedies under this Agreement or any Ancillary Agreement or (ii) to comply with their respective regulatory, stock exchange, Tax, accounting or financial reporting requirements, and shall keep confidential and exercise the same degree of care
with respect to maintaining the confidentiality of any Seller Information in any of their possession that Buyer exercises with respect to similar types of its own proprietary information, but in no event less than a reasonable degree of care, except
that if any Seller Information is required by Law or legal or administrative process to be disclosed, Buyer shall promptly (and in any event prior to making such disclosure, to the extent permitted by Law) notify Seller of such disclosure
requirement so that Seller or its Affiliates may seek a protective Order or other appropriate remedy. Buyer shall, and shall direct its Representatives to, reasonably cooperate, at Seller’s expense, with Seller’s or Affiliate’s
efforts to obtain such protective Order or other appropriate remedy. In the event that no such protective Order or other remedy is obtained, or Seller does not waive compliance with this Section 12.3(c), and Buyer or its
Representatives are nonetheless legally compelled to disclose such Seller Information, Buyer or its Representatives, as the case may be, will furnish only that portion of the Seller Information which Buyer or its Representatives are advised by
counsel is legally required to be furnished and will give Seller written notice of the Seller Information to be disclosed as far in advance as reasonably practicable and exercise all reasonable efforts to obtain reliable assurance that confidential
treatment will be accorded the Seller Information. For purposes of this Section 12.3(c), the term “Seller Information” means (i) all information, knowledge and data provided in connection with
the Transactions by Seller or its Affiliates to Buyer to the extent related to any business other than the Business, any compound or product other than any Compound or Product, any Excluded Assets or any Excluded Liabilities, and (ii) all
analyses, compilations, forecasts, studies, interpretations, summaries, notes, data and other documents and materials (in any form or medium of communication, whether written, oral, electronic or magnetic), whether prepared by Buyer, Buyer’s
Representatives or others, which contain, reflect or are generated from or based upon, in whole or in part, the information referred to in clause (i) of this sentence, other than any such information that (A) is known to Buyer prior to
receipt thereof from Seller or any of its Affiliates, (B) is disclosed to Buyer by a Third Party which has, or is reasonably believed by Buyer to have, a legal right to make such disclosure without requiring Buyer to maintain the
confidentiality thereof, (C) is or becomes part of the public domain through no fault of Buyer, or (D) is independently developed by or for Buyer, without reliance on or reference to any information received from Seller or any of its
Affiliates.

 12.4 Expenses. Whether or not the Transactions are consummated, and except as
otherwise specified herein, including Section 6.2(f), each Party shall bear its own costs and expenses in connection with this Agreement and the Ancillary Agreements and with respect to the Transactions. 

12.5 Severability. In the event that any provision of this Agreement or the application thereof becomes or is declared by an arbitration
panel or court of competent jurisdiction to be illegal, void or unenforceable, the remainder of this Agreement will continue in full force and effect and the application of such provision to other Persons or circumstances will be interpreted so as
reasonably to effect the intent of the Parties. Further, the Parties agree to replace such void or unenforceable provision of this Agreement with a valid and enforceable provision that will achieve, to the greatest extent possible, the economic,
business and other purposes of such void or unenforceable provision. 
 12.6 Entire Agreement; Amendment. This Agreement, the
Confidentiality Agreement, the Ancillary Agreements (including the Transfer Documents after their execution and delivery hereunder), the Seller Disclosure Letter and the Buyer Disclosure Letter contain the entire agreement of the Parties with
respect to the Transactions, superseding all negotiations, prior discussions and preliminary agreements made prior to the date hereof. This Agreement may not be amended, supplemented or otherwise modified except by an instrument in writing signed by
both Seller and Buyer. 
 12.7 No Third-Party Beneficiaries. This Agreement is solely for the benefit of the Parties and, to the
extent set forth herein, their respective Affiliates and the Indemnified Parties, and no provision of this Agreement shall be deemed to otherwise confer upon any other Third Parties any remedy, Claim, Liability, reimbursement or other right in
excess of those existing without reference to this Agreement. 
 12.8 Waiver. The waiver by a Party of any breach of any of the terms,
covenants or conditions of this Agreement or of any right or privilege conferred by this Agreement shall not be construed as a subsequent waiver of any such terms, covenants, conditions, rights or privileges or as a waiver of any other terms,
covenants, conditions, rights or privileges. No waiver shall be effective unless it is in writing and signed by an authorized representative of the waiving Party. 

12.9 Governing Law. This Agreement (and any Claim or controversy arising out of or relating to this Agreement or the Transactions) shall
be governed by and construed in accordance with the Laws of the State of Delaware without giving effect to any choice or conflict of law provision or rule that would cause the application of the Laws of any jurisdiction other than the State of
Delaware. 
 12.10 Arbitration. 

(a) Subject to Section 12.11, and except for any dispute to be resolved under
Section 2.7(d), any dispute arising under or relating to this Agreement (including any dispute relating to the existence, validity, termination, or breach hereof) or the Transactions shall be fully and finally resolved by
binding arbitration under the Rules of Arbitration of the International Chamber of Commerce in effect at the time of execution of this Agreement (the “ICC Rules”) in accordance with this Section 12.10. A
Party shall institute arbitration by issuing a written demand for arbitration to the other Party in accordance with the ICC Rules and Section 12.16. Any such 

  
 -72- 

 
arbitration shall be held in New York, New York. The arbitration shall be conducted in the English language by a panel of three (3) arbitrators appointed in accordance with the ICC Rules;
provided, that: (i) each Party shall within thirty (30) days after the institution of the arbitration appoint an arbitrator, and such party-appointed arbitrators shall together, within thirty (30) days after they both have been
appointed, and in consultation with the parties, select a third arbitrator as the president of the arbitration panel; and (ii) each arbitrator shall be conflict-free with respect to each Party and its Affiliates and any Payment Obligors. If
either Party fails to appoint an arbitrator as provided above or the two (2) Party-appointed arbitrators shall fail for any reason to select a third arbitrator to serve as president within the applicable thirty
(30)-day period, then such arbitrator(s) shall be promptly appointed by the ICC in accordance with the ICC Rules. Notwithstanding the foregoing, neither Party shall be precluded from seeking interim or
injunctive relief in any forum of competent jurisdiction, and such action shall not be incompatible with the agreement to arbitrate contained herein or the availability of interim measures of protection under the ICC Rules. 

(b) The arbitrators shall render a final reasoned award within sixty (60) days of the final arbitration hearing. A decision by any two
(2) or more of the arbitrators in any ruling or award shall be a binding decision of the arbitral panel. Each Party hereby waives any and all rights that it may have to appeal or challenge any award of the arbitral panel, in any jurisdiction,
to the fullest extent allowable by law. Any award rendered by the arbitrators shall be final and may be entered and enforced in any court of competent jurisdiction. The Parties hereby consent to the jurisdiction of such courts for purposes of
enforcement of any such award. No arbitrator (nor the panel of arbitrators) shall have the power to award punitive damages under this Agreement, and any such award is expressly prohibited. Unless otherwise determined by the panel of arbitrators,
which shall have the authority to determine an allocation of each Party’s costs and expenses incurred in connection with the dispute that is subject to the arbitration proceeding (including fees of the arbitrators and the Parties’
respective other out-of-pocket costs and expenses), each Party shall pay its attorneys’ fees and shall equally share the arbitration costs. Except in a proceeding
to enforce the results of the arbitration or as otherwise required by applicable Law, neither Party nor any arbitrator may disclose the existence, content, or results of any arbitration hereunder without the prior written consent of the other Party.

 12.11 Specific Performance. The Parties agree that irreparable damage may occur in the event that any of the provisions of this
Agreement were not performed in accordance with their specific terms or were otherwise breached or threatened to be breached. It is accordingly agreed that the Parties shall be entitled (without proof of actual damages or otherwise or posting or
securing any bond) to seek an injunction or injunctions to prevent breaches of this Agreement and to seek to enforce specifically the terms and provisions of this Agreement, these being in addition to any other remedy to which they are entitled at
law or in equity. The Parties further agree not to assert that a remedy of specific performance is unenforceable, invalid, contrary to Law or inequitable for any reason, nor to assert that a remedy of monetary damages would provide adequate remedy.
Each of the Parties acknowledges and agrees that the right to seek specific performance and the other relief contemplated herein is an integral part of the Transactions and without such right, none of the Parties would have entered into this
Agreement. 

  
 -73- 

 12.12 Representation by Counsel. Each Party represents and agrees with each other
that it has been represented by or had the opportunity to be represented by independent counsel of its own choosing, and that it has had the full right and opportunity to consult with its respective attorney(s), that to the extent, if any, that it
desired, it availed itself of this right and opportunity, that it or its authorized officers (as the case may be) have carefully read and fully understand this Agreement and the Ancillary Agreements in their entirety and have had them fully
explained to them by such Party’s respective counsel, that each is fully aware of the contents thereof and their meaning, intent and legal effect, and that it or its authorized officer (as the case may be) is competent to execute this Agreement
and has executed this Agreement free from coercion, duress or undue influence. 
 12.13 English Language. This Agreement shall be
written and executed in, and all other communications under or in connection with this Agreement shall be in, the English language. Any translation into any other language shall not be an official version thereof, and in the event of any conflict in
interpretation between the English version and such translation, the English version shall control.

binding to the same extent as an original signature page, with regard to any agreement subject to the terms hereof or any amendment thereto and may be used in lieu of the original signatures for all purposes. Any Party that delivers such a signature
page agrees to later deliver an original counterpart to any Party that requests it. 
 12.16 Notices. All notices and other

 Exhibit A 

Bill of Sale and Assignment and Assumption Agreement 

[See Attached] 

  
 A-1 

 BILL OF SALE AND ASSIGNMENT AND ASSUMPTION AGREEMENT 

This Bill of Sale and Assignment and Assumption Agreement (this “Agreement”) is made and entered into as of [•], 2021,
by and between Fusion Pharmaceuticals Inc., a Canadian federal corporation (“Buyer”), and Ipsen Pharma SAS, a French société par actions simplifiée
(“Seller”). Seller and Buyer are sometimes referred to in this Agreement collectively as the “Parties” and individually as a “Party”. All capitalized terms used but not otherwise defined
herein shall have the respective meanings set forth in the Purchase Agreement (as defined herein). 
 WHEREAS, Buyer and Seller have
entered into that certain Asset Purchase Agreement, dated as of March 1, 2021 (the “Purchase Agreement”), pursuant to which, among other things, and subject to the terms and conditions thereof, (a) Seller has agreed to
grant, sell, transfer, convey, assign and deliver to Buyer all right, title, and interest of Seller in and to the Acquired Assets, and (b) Buyer has agreed to purchase and accept from Seller the Acquired Assets and to assume the Assumed
Liabilities (collectively, the “Transaction”); and 
 WHEREAS, contingent upon the occurrence of the Closing and
subject to the terms and conditions of the Purchase Agreement, Seller and Buyer are hereby effectuating the assignment, transfer, conveyance, and delivery of all right, title, and interest of Seller in, to, and under the Acquired Assets. 

NOW, THEREFORE, in consideration of the foregoing, the mutual covenants, and agreements set forth in this Agreement, and for other good
and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties, intending to be legally bound hereby, agree as follows: 

1. Asset Transfer. Upon the terms and subject to the conditions set forth in the Purchase Agreement, Seller hereby grants, sells,
transfers, conveys, assigns and delivers to Buyer and Buyer hereby purchases and accepts from Seller, free and clear of all Liens other than Permitted Liens, all of Seller’s right, title, and interest in, to, and under the Acquired Assets,
which may be held and enjoyed by Buyer for its own use and for the use of its successors, assigns, and other legal representatives. 
 2.
Assumed Liabilities. Upon the terms and subject to the conditions set forth in the Purchase Agreement, Buyer hereby assumes and agrees to satisfy and discharge the Assumed Liabilities. 

3. Excluded Assets and Excluded Liabilities. Seller shall retain all right, title, and interest in, to, and under the Excluded Assets.
Seller shall retain, and Buyer shall not assume, any of the Excluded Liabilities. 
 4. Approvals; Consents. This Agreement shall not
constitute an agreement to grant, sell, transfer, convey, assign or deliver any Acquired Asset (each, a “Required Consent Asset”) to the extent that such grant, sale, transfer, conveyance, assignment or delivery requires the Consent
of another Person (other than Seller, Buyer, or any of their respective Affiliates) that shall not have been given prior to the Closing. The grant, sale, transfer, conveyance, assignment and delivery shall not be deemed effective with respect to
such Required Consent Asset until such time as the Consent of such Person shall have been obtained pursuant to Section 2.5 of the Purchase Agreement, whereupon, 

  
 A-2 

 
subject to Section 2.5 of the Purchase Agreement and applicable Law, (a) this Agreement and the Purchase Agreement shall then constitute an agreement to grant, sell, transfer, convey,
assign and deliver such Required Consent Asset, (b) such grant, sale, transfer, conveyance, assignment and delivery will be deemed effective without any further action of Seller or Buyer, and (c) this Agreement shall apply to such Required
Consent Asset without any further action of Seller or Buyer. 
 5. Further Assurances. Seller shall, and shall cause its applicable
Subsidiaries to, at any time and from time to time after the Closing Date, upon the request of Buyer, do, execute, acknowledge, deliver and file, or cause to be done, executed, acknowledged, delivered or filed, all such further acts, deeds,
transfers, conveyances, assignments or assurances as may be reasonably required for the better transferring, conveying, assigning and assuring to Buyer, or for the aiding and assisting in the reducing to possession by Buyer of, any of the Acquired
Assets, or for otherwise carrying out the purposes of this Agreement and the Transaction. 
 6. Conflicts. This Agreement is subject
in all respects to the terms and conditions of the Purchase Agreement, which are incorporated herein by reference. This Agreement is given to further evidence (and give immediate effect to) the transfers and assignments contemplated by the Purchase
Agreement upon the terms and conditions specified therein. Nothing contained in this Agreement, express or implied, shall in any way supersede, modify, replace, amend, change, rescind, waive, exceed, expand, reduce, enlarge, or in any way affect the
provisions, including warranties, covenants, agreements, conditions, representations, or, in general, any of the rights and remedies, and any of the obligations, of Seller or Buyer as set forth in the Purchase Agreement. In the event of any
conflict, ambiguity or inconsistency between the terms of this Agreement and the terms of the Purchase Agreement, the applicable terms of the Purchase Agreement shall be deemed to be controlling and will govern. 

7. Governing Law; Arbitration. This Agreement (and any Claim or controversy arising out of or relating to this Agreement or the
Transaction) shall be governed by and construed in accordance with the Laws of the State of Delaware without giving effect to any choice or conflict of law provision or rule that would cause the application of the Laws of any jurisdiction other than
the State of Delaware. The Parties agree that the resolution of all disputes under or in connection with this Agreement shall be governed in accordance with Section 12.10 of the Purchase Agreement. 

8. Severability. In the event that any provision of this Agreement or the application thereof becomes or is declared by an arbitration
panel or court of competent jurisdiction to be illegal, void or unenforceable, the remainder of this Agreement will continue in full force and effect and the application of such provision to other Persons or circumstances will be interpreted so as
reasonably to effect the intent of the Parties. Further, the Parties agree to replace such void or unenforceable provision of this Agreement with a valid and enforceable provision that will achieve, to the greatest extent possible, the economic,
business and other purposes of such void or unenforceable provision. 
 9. Entire Agreement; Amendment. This Agreement and the
Purchase Agreement contain the entire agreement of the Parties with respect to the Transaction, superseding all negotiations, prior discussions and preliminary agreements made prior to the date hereof. This Agreement may not be amended, supplemented
or otherwise modified except by an instrument in writing signed by both Seller and Buyer. 

  
 A-3 

 10. Assignment. 

 

	 	a.	 Except as expressly permitted herein or in connection with an assignment of the Purchase Agreement permitted in
accordance with the terms thereof, this Agreement may not be assigned or transferred by either Party in whole or in part, nor may any Party assign or transfer any rights or obligations created by this Agreement, in each case, whether by operation of
Law, assignment, succession or otherwise, without the prior written consent of the other Party, which consent will not be unreasonably withheld, conditioned or delayed. 

 

	 	b.	 The terms of this Agreement will be binding upon and will inure to the benefit of the successors, heirs,
administrators and permitted assigns of the applicable Party. Any purported assignment in violation of this Section 10(b) will be null and void ab initio. 

11. No Third Party Beneficiaries. This Agreement is solely for the benefit of the Parties and, to the extent set forth herein, their
respective Affiliates, and no provision of this Agreement shall be deemed to otherwise confer upon any other Third Parties any remedy, Claim, Liability, reimbursement or other right in excess of those existing without reference to this Agreement.

 12. Waiver. The waiver by a Party of any breach of any of the terms, covenants or conditions of this Agreement or of any right or
privilege conferred by this Agreement shall not be construed as a subsequent waiver of any such terms, covenants, conditions, rights or privileges or as a waiver of any other terms, covenants, conditions, rights or privileges. No waiver shall be
effective unless it is in writing and signed by an authorized representative of the waiving Party. 
 13. Counterparts; Signature
Pages. The Parties may execute this Agreement in one or more counterparts, each of which will be deemed an original and all of which, when taken together, will be deemed to constitute one and the same agreement. Any signature page hereto
delivered by e-mail (including in portable document format (PDF)) shall be binding to the same extent as an original signature page, with regard to any agreement subject to the terms hereof or any amendment
thereto and may be used in lieu of the original signatures for all purposes. Any Party that delivers such a signature page agrees to later deliver an original counterpart to any Party that requests it.

 Exhibit 10.1 

CONSULTING AGREEMENT 

This Consulting Agreement (as it subsequently may be amended from time to time, this “Agreement”) is entered into as
of February 28, 2021 (“Effective Date”) by and among John D. Sims (“Consultant”) and Allegheny Technologies Incorporated (together with its affiliates, the
“Company”). 
 RECITALS 

WHEREAS, Consultant has retired from his position with the Company as Senior Advisor to the CEO, having previously served as the Company’s
Executive Vice President, High Performance Materials and Components; 
 WHEREAS, the Company desires to retain Consultant to provide
independent consulting services to Company; 
 WHEREAS, Consultant and the Company have determined it to be necessary, desirable and
appropriate to set forth the terms and conditions of their new consulting relationship in this Agreement; 
 WHEREAS, in recognition of
their new consulting arrangement and for other good and valuable consideration described herein, (a) Consultant and the Company have further determined it to be necessary, desirable and appropriate to include in this Agreement provisions
relating to confidentiality, noncompetition, non-solicitation and non-disparagement, and (b) Consultant has agreed to provide the Company with a general release of
claims. 
 NOW, THEREFORE, in consideration of the foregoing and other good and valuable consideration, the receipt and sufficiency of which
hereby is acknowledged, Consultant and the Company hereby agree as follows: 
 ARTICLE I 

TERM; PAYMENTS 

1.1    Term. Subject to earlier termination as provided below in Article IV, the term of this
Agreement (the “Term”) shall begin on the Effective Date and shall expire on December 31, 2021, unless otherwise agreed in writing by the parties. 

1.2    Consulting Payments. In consideration of Consultant’s services hereunder and his
agreement to comply with the provisions of this Agreement, Consultant shall (a) receive a consulting payment (“Consulting Payment”) of $45,480.76 every month during the Term, beginning in March 2021 and payable in each
month no later than the last business day of such month, provided for the sake of clarity that no event shall and Consulting Payments be made for services provided under this Agreement beyond December 31, 2021 unless otherwise agreed in writing
by the parties, and (b) be eligible to earn a performance bonus (“Performance Bonus”) in the aggregate amount of up to $150,000, payable in three installments of up to $50,000 each on each June 30, 2021,
September 30, 2021 and December 31, 2021, contingent in the case of each such potential payment on an evaluation of Consultant’s success in supporting the transition of his prior leadership role to his successor and in otherwise
executing his duties and obligations under this Agreement from the date of this agreement through the relevant quarterly period, as determined by the Company’s Chief Executive Officer in his sole discretion. 

 1.3    Continuation of Coverage Under the Company’s
Medical Plan. Provided that Consultant has elected and he and/or any of his current dependents remains eligible for continuation coverage under the Consolidated Omnibus Reconciliation Act of 1985 (“COBRA”), the
Company will make eighteen (18) COBRA continuation payments on his or their behalf. If, through no fault of his own, Consultant becomes Medicare-eligible during the period for which Company-paid COBRA continuation premiums would be made under
this Agreement, the Company will pay to Consultant (or, in the event of Consultant’s death, his estate) the financial equivalent of the value of any remaining COBRA subsidy he would otherwise have received. 

1.4    Additional Medical Coverage Subsidy. In further consideration of Consultant’s
agreement to comply with the provisions of this Agreement and the Release (as defined in Section 3.6 below), within thirty (30) days following the Effective Date, the Company shall make a single lump sum payment to Consultant equal to
$23,080.32. 
 1.5    Taxes. The Company will not withhold any part of any payment to Consultant
hereunder for the payment of any social security, federal, state or any other employee payroll taxes and will not make unemployment insurance or disability insurance contributions or obtain workers’ compensation insurance on Consultant’s
behalf. Company will regularly report amounts paid to Consultant by filing a Form 1099-MISC with the Internal Revenue Service as required by law. 

1.6    Acknowledgment. Consultant acknowledges that he is not entitled to participate in the
Company’s Annual Incentive Plan or any other short-term incentive program for 2021 or any year thereafter, that he will not receive any equity or other award under any long-term incentive plan or program for 2021 or at any time after the
Effective Date, and that nothing in this Agreement is intended in any way to alter the terms and conditions of any long-term equity award outstanding as of the Effective Date, which awards have or shall vest and be paid, if at all, in accordance
with the terms and conditions set forth in the award agreements governing such awards. For the avoidance of doubt, the parties acknowledge that the Consultant’s prior retirement from the Company constituted his separation of service from the
Company within the meaning of Treasury Regulation 1.409A-1(h) and for purposes of Section 409A of the Internal Revenue Code of 1986, as amended.    For this purpose, a separation from
service is deemed to occur at any time that the bona fide level of services the Consultant will perform (whether as an employee or an independent contractor) is permanently reduced to a level that is less than fifty percent (50%) of the average
level of bona fide services he performed during the immediately preceding 36 months. 
 ARTICLE II 

CONSULTING SERVICES AND RELATED PROVISIONS 

2.1    Consulting Services. During the Term, Consultant agrees to provide such consulting services to
Company as the Company may reasonably request from time to time, provided, however, that at no time during the Term shall the level of services provided by Consultant exceed fifty percent (50%) of the average level of bona fide
services performed by Consultant in his capacity as an employee over the thirty-six (36) month period immediately preceding the Effective Date. 

2.2    Independent Contractor Status. Consultant is a self-employed independent contractor, and
nothing in this Agreement shall create an employer-employee relationship between Consultant, anyone acting on his behalf, and the Company. 

  
 2 

 (a)    Except as otherwise provided in this Agreement, Consultant will
have control over the manner and means of performing services under this Agreement. The Company, however, reserves the right to be notified of and approve in advance and in its sole and absolute discretion, Consultant’s use of any employee,
consultant, or agent to complete such services. Consultant’s exercise of such right of approval will in no way limit Consultant’s obligations under this Agreement or his status as an independent contractor. 

(b)    Consultant is solely responsible for: (i) maintaining insurance of any type for himself and anyone acting on
his behalf; (ii) all tax returns and payments required to be filed with or made to any federal, state, or local tax authority with respect to the performance of services and receipt of fees or other payments under this Agreement; and
(iii) any licensing or other legal requirements in connection with the provision of services under this Agreement. 

2.3.    Reimbursement of Covered Expenses. The Company shall reimburse Consultant for all reasonable
travel, parking, and other expenses that he incurs during the Term directly in connection with the provision of specific consulting services requested by the Company, provided that Consultant provides documentation of such expenses in a form
substantially similar to the documentation required by the Company’s expense reimbursement policies for like expenses. All reimbursement payments with respect to expenses incurred within a particular year shall be made no later than the end of
the Consultant’s taxable year following the taxable year in which the expense was incurred. The amount of reimbursable expenses incurred in one taxable year of the Consultant shall not affect the amount of reimbursable expenses in a different
taxable year and such reimbursement shall not be subject to liquidation or exchange for another benefit. 
 ARTICLE III 

CONSULTANT’S COVENANTS 

3.1    Non-Disclosure of Confidential Information; Non-Interference with Rights. 
 (a)    Consultant shall not use, divulge or
otherwise disclose, directly or indirectly, any trade secret or other proprietary or confidential information (“Confidential Information”) concerning the business or policies of Company which he may have learned as an officer
or employee of Company or which he may learn during the Term, except to the extent such use or disclosure is (i) necessary to the performance of this Agreement and in furtherance of Company’s best interests, (ii) required by
applicable law, (iii) lawfully obtainable from other sources, or (iv) authorized by Company. Confidential Information includes, without limitation, confidential information and Company trade secrets, whether in tangible or intangible form,
regarding the Company’s: products; services; near and long-term business strategies, plans and expectations; marketing strategies; business plans; operations; costs; current or prospective customer information (including without limitation
customer lists, requirements, creditworthiness, preferences, pricing information, sales volume, margins and similar matters); product concepts; designs; specification; technical data and know-how; purchasing
information (including without limitation pricing, sales information and other terms and conditions of sale); financial information; internal procedures or techniques; forecasts; trade information; software programs; project requirements, and all
other information that is not generally known to those outside of the Company. Confidential Information also includes the information of any other person or entity that the Company has an obligation to maintain as confidential. The provisions of
this Section 3.1 shall survive the expiration or termination, for any reason, of the Term. 
 (b)    Nothing in
this Agreement prevents Consultant from initiating communications directly with, or responding to any inquiry from, or providing truthful information in any legal or governmental proceeding or investigation. Additionally, nothing in this Agreement
prohibits Consultant from reporting, disclosing, or discussing conduct that constitutes unlawful 

  
 3 

 
discrimination, harassment, or sexual assault.    In accordance with the Defend Trade Secrets Act of 2016, notwithstanding any other provision of this Agreement or the
provisions contained in the agreements consented to or signed by Consultant during employment, Consultant will not be held criminally or civilly liable under any federal or state trade secret law for any disclosure of a trade secret that:
(i) is made (A) in confidence to a federal, state or local government official, either directly or indirectly, or to an attorney; and (B) solely for the purpose of reporting or investigating a suspected violation of law; and
(ii) is made in a complaint or other document that is filed under seal in a lawsuit or other proceeding. If Consultant files a lawsuit for retaliation by the Company for reporting a suspected violation of law, Consultant may disclose the
Company’s trade secrets to his attorney and use the trade secret information in the court proceeding if Consultant: (A) files any document containing the trade secret under seal and (B) does not disclose the trade secret except
pursuant to court order. 
 3.2    Non-Solicitation and Non-Competition. 
 (a)    Company’s Investment.
Consultant understands that the Company has spent and will continue to spend substantial amounts of time, money and effort to develop its business, Confidential Information, reputation, goodwill (both associated with its trade names and geographic
areas of business), and its customer, suppler and employee relationships. Consultant further understands that he has, and will continue to, benefit from those investments and efforts, and acknowledges that the Company would not enter into this
Agreement or provide Consultant with the consideration and benefits accruing to him under this Agreement without his express agreement to be bound by the provisions of this Agreement, including but not limited to those set forth in this
Section 3.2. 
 (b)    Non-Solicitation. Consultant
shall not, either for his own account or for or on behalf of any other person or entity, directly or indirectly, take any of the following actions during the Term and through and including December 31, 2022 (the “Restricted
Period”): 
 (i)    Solicit any employee of the Company with the intention of encouraging such person to
terminate the person’s employment with the Company; 
 (ii)    Solicit or transact business with any Customer (as
defined below) for the purpose of offering any service or product offered by the Company or any service or product that directly or indirectly competes with or is substantially similar to such service or product (hereafter, “Competitive
Services”). “Customer” means (A) any current or former customer of the Company (1) with whom Consultant had material contact in the performance of his duties at any time during the 24-month period preceding the Effective Date or during the Term, or (2) about whom Consultant has knowledge of Confidential Information; (B) any person or entity who contacted the Company, at any time
during the 6-month period preceding the Effective Date, for the purpose of seeking or obtaining the Company’s services; or (C) any person or entity whom the Company contacted, at any time during the 6-month period preceding the Effective Date, for the purpose of providing or selling the Company’s services; 

(iii)    Solicit or transact business with any Customer, vendor, contractor or supplier of the Company for the purpose of
encouraging such person to terminate its relationship with the Company or to place elsewhere or reduce the volume of its business with the Company; or 

(iv)    Otherwise attempt to directly or indirectly interfere with the Company’s business or relationships with its
employees, independent contractors, vendors, suppliers, or Customers when such activities will involve the inevitable use of, or near certain influence by Consultant’s knowledge of, Confidential Information disclosed to the Consultant during
the term of Consultant’s employment with the Company or during the Term of this Agreement. 

  
 4 

(c)    Non-Competition. Consultant shall not, either for his
own account or for or on behalf of any other person or entity, directly or indirectly, take any of the following actions during the Restricted Period as defined above: 

(i)    Have an ownership or financial interest in a “Competitor,” defined as any person or entity
(including Consultant or an entity that Consultant becomes employed by or otherwise affiliated with or renders services to) that offers, or is actively planning to offer, Competitive Services within a “Restricted Territory”
defined as the geographic area where the Company did business during Consultant’s employment or does or actively plans to do business during the Term of this Agreement and where Consultant’s use or disclosure of Confidential Information
would materially disadvantage the Company regardless of Consultant’s physical location, provided that Consultant’s passive ownership of securities of a publicly held Competitor does not violate this provision, so long as
Consultant’s ownership does not exceed 0.5% of such Competitor’s issued and outstanding voting stock; 

(ii)    Advise or consult with a Competitor concerning Competitive Services in the Restricted Territory; 

(iii)    Be employed by or provide services to or for a Competitor in the Restricted Territory where Consultant’s
duties are the same as, or similar to, the duties that Consultant performed on behalf of the Company at any time during the 24-month period preceding the Effective Date; or 

(iv)    Otherwise engage in the production, marketing, sale, distribution, offering or provision of Competitive Services
in the Restricted Territory. 
 3.3    Non-Disparagement.
Consultant agrees that he will not, in any way, disparage the Company to any person(s) or organization(s), including without limitation any employee of the Company. A disparaging statement is any communication, oral or written, including electronic
postings on social media, which would cause or tend to cause the recipient of the communication to question the business condition, integrity, legal compliance, competence, fairness, quality of services, or good character of the person or entity to
whom or to which the communication relates. 
 3.4    Cooperation. Consultant agrees to cooperate
with the Company in the prosecution or defense of claims asserted by or against it or the investigation of potential claims and shall be available, by telephone, video conference or in person, at such reasonable times as may be requested by the
Company, to discuss and consult with employees or agents of the Company with respect to business matters of the Company. Such cooperation and consultation shall including meeting with representatives of the Company or the Company’s attorneys,
or both, divulging to the Company any information that the Company may request for possible use in the conduct of its business or in litigation, arbitration, investigations (whether internal or external) or other legal proceeding, and testifying on
behalf of the Company at the Company’s request. The Company agrees to reimburse Consultant for reasonable personal expenses incurred by Consultant pursuant to this Section 3.4, in accordance with the procedures set forth in
Section 2.3. 
 3.5    Future Employment. During the Restricted Period, Consultant agrees
(a) to notify the Company in writing of the name and address of any new person or entity by whom or which Consultant becomes employed or for whom or which Consultant agrees to perform consulting or other services and (b) to provide such
person or entity with a copy of this Agreement. 

  
 5 

 3.6    Release. In consideration for the
Company’s entering into this Consulting Agreement and providing the payments and benefits contained herein, including without limitation the additional medical coverage subsidy provided in Section 1.5 hereof, the Consultant agrees to
execute and not revoke a general release of claims in the form provided by the Company (“Release”) within the time period specified therein. 

ARTICLE IV

of guilty or nolo contendere to a charge of commission of a felony, or (iii) the willful engaging by the Consultant in gross misconduct that is injurious to the Company. 

(b)    If Consultant shall be temporarily prohibited from participating in the conduct of the Company’s affairs by
any regulatory authority having jurisdiction in the premises, the Company’s obligations shall be automatically suspended, subject to reinstatement in full if the charges resulting in such prohibition are finally dismissed. Such reinstatement
shall provide Consultant with the Consulting Payments and other payments to which he would have been entitled absent such prohibition to the same effect and extent as though such prohibition had not occurred. 

(c)    The Company’s election to terminate Consultant’s consulting arrangement pursuant to this Section 4.1
shall not affect the Company’s right to enforce each of the covenants of Consultant provided for in Article III of this Agreement or the Release. 

4.2    Termination by Consultant. By providing prior written notice of at least ninety
(90) days, Consultant shall be entitled to terminate the Term for any reason or for no stated reason. Upon any such termination: (a) Consultant shall cease to have the right to receive the monthly Consulting Payment described above in
Section 1.1 for calendar months after the effective date of the termination; (b) Consultant’s obligations under Article II above shall continue in accordance with the terms thereof through December 31, 2022; (c) Consultant shall
be relieved of his obligations under Section 2.1 above as of the effective date of such termination; and (iv) Company shall be relieved of its obligation under this Agreement as of the effective date of such termination. 

4.3    Consultant’s Death. Notwithstanding anything to the contrary in this Agreement, the Term
shall terminate immediately upon Consultant’s death. Upon any termination of the Term because of Consultant’s death, (a) Consultant’s estate shall cease to have the right to receive the Consulting Payment described above in
Section 1.2(a) for any period of time after the effective date of the termination, (b) the Company shall pay, within thirty (30) days following Consultant’s death, a pro-rated any earned
but unpaid quarterly portion of Consultant’s Performance Bonus described above in Section 1.2(b) (the pro-rated amount to be determined by multiplying the amount of the relevant quarterly installment
earned as determined in accordance with Section 1.2(b) by a fraction, the denominator of which is the number of calendar days in the relevant quarter and the numerator of which is the number of days from and including the first day of the
quarter through and including the day of Consultant’s death) , and (c) the Company shall continue making any remaining COBRA continuation payments as described in Section 1.3 of this Agreement or, in the event that Consultant dies
after becoming Medicare eligible but prior to the Company’s payment of the lump sum described in Section 1.3, will make such lump sum payment to Consultant’s estate.

 ARTICLE V 

MISCELLANEOUS PROVISIONS 

5.1    Limitation of Authority. Consultant acknowledges that as a result of the cessation of
his common law employee relationship with the Company and the commencement of his new relationship as an independent contractor, Consultant shall not, for any purpose, be considered in employee, representative or agent of the Company, and he no
longer has authority or any other ability to enter into agreements on behalf of, or to otherwise obligate, the Company. 

5.2    Severability. Should any provision of this Agreement be declared illegal or
unenforceable by any court of competent jurisdiction and if such provision cannot be modified to be enforceable (including the general release language), such provision shall immediately become null and void, leaving the remainder of the Agreement
in full force and effect. Notwithstanding the foregoing, if a court of competent jurisdiction determines that the scope of the restrictive covenants in Article III of this Agreement exceed the maximum restrictiveness such court deems reasonable and
enforceable, the parties intend that the court should reform, modify and enforce the provision to such narrower scope as it determines to be reasonable and enforceable. 

5.3    Injunctive Relief. In the event of a breach by Consultant of any of the provisions of
this Agreement, the Company shall be entitled, if it shall so elect, to institute legal proceedings to obtain damages for any such breach or to enforce the specific performance of this Agreement by Consultant and to enjoin him from any further
violation of this Agreement and to exercise such remedies cumulatively or in conjunction with all other rights and remedies provided by law. Consultant acknowledges that the remedies at law for any breach of this Agreement may be inadequate, and
that the Company shall be entitled to injunctive relief in the event of a breach of this Agreement. Consultant acknowledges that his breach or threatened breach of the covenants in Article III of this Agreement would cause the Company irreparable
harm, and that the Company would be entitled to seek extraordinary relief in court, including temporary restraining orders, preliminary or permanent injunctions, or other equitable relief, without the necessity of showing any actual damages or that
money damages would not afford an adequate remedy, and without the necessity of posting any security. If Consultant breaches any of the restrictive covenants in Article III, to the extent authorized by law, Consultant will be responsible for the
reasonable attorneys’ fees and costs the Company incurs in enforcing this Agreement. Additionally, if Consultant violates any of the terms of the restrictive covenants in Article III, the Restricted Period shall be automatically extended by the
period Consultant was in violation of such covenant(s). 
 5.4    Entire Agreement. This
Agreement constitutes the entire agreement of the parties and supersedes all prior negotiations, understandings and agreements, proposed or otherwise, written or oral, concerning the subject matters of this Agreement. However, this Agreement shall
not supersede any obligation of Consultant under any agreement concerning confidentiality, trade secrets, proprietary information, non-disclosure, inventions, patents, copyrights or intellectual property that
Consultant previously executed, and any such agreement shall continue to remain in full force and effect. Consultant agrees that he has not relied on any representation or statement, whether written or oral, other than as set forth in this
Agreement. Furthermore, no modification of this Agreement shall be binding unless in writing signed by both parties. 

5.5    Successors and Assigns. This Agreement shall be binding upon, and shall inure to the
benefit of, the respective heirs, executors, legal representatives and other successors and assigns of the parties to this Agreement, except that Consultant is not permitted to assign his rights under this Agreement. Nothing in this Agreement shall
preclude the Company from 

  
 7 

 
consolidating or merging into or with, or transferring all or substantially all of its assets to, another corporation or entity which assumes this Agreement and all obligations and undertakings
of the Company hereunder. Upon such consolidation, merger or transfer of assets and assumption, the term “Company” as used herein shall mean such other corporation or entity, and this Agreement shall continue in full force and effect. 

5.6     Construction. The language of all sections of this Agreement shall in all cases be construed
as a whole, according to its fair meaning and not strictly against the drafter of the language of this Agreement. 

5.7    Judicial Enforcement. This Agreement may be specially enforced in judicial proceedings. 

5.8    Counterparts; Section Headings; Gender and Number. This Agreement may be executed in
two or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. The section headings of this Agreement are for convenience of reference only and shall not affect the
construction or interpretation of any of the provisions of this Agreement. Where appropriate to the context of this Agreement, (a) use of the singular shall be deemed also to refer to the plural and use of the plural to the singular, and
(b) the use of the word “its” or another word denoting any gender shall include all genders. 

5.9    Notices. Any notice or other communication required or permitted by this Agreement to
be delivered by one party to another must be in writing and personally delivered or sent by registered United States mail (return receipt requested and postage prepaid), by overnight delivery or by facsimile transmission, to the address for such
party specified below or to such other address as the party may from time to time advise the other parties, and shall be deemed to have been delivered upon actual personal delivery, on the first business day after the date of delivery shown on any
such facsimile transmission, three days after deposit in the United States mail or one day after delivery to an overnight delivery service, as the case may be.
