 WHEREAS, Participant
previously executed a certain Amended and Restated Consulting Agreement dated May 20, 2020 with the Company (the “Consulting Agreement”). 

WHEREAS, Participant is a valued advisor of the Company and the Company has determined that it is appropriate to award certain Business

(a) Subject to the terms and conditions herein and provided that the Participant remains in a continued consulting relationship with the
Company or its Affiliates, if the Company receives BD Cash Payments in a range set forth in the table below, Participant will become eligible for the corresponding Total Amount of Earned Cash Bonus and the Company will pay Participant the difference

and such eligibility is confirmed by the Compensation Committee. Notwithstanding anything contrary contained herein, including the foregoing sentence, if the Total BD Cash Payments is below [*],
the corresponding Total Amount of Earned Cash Bonus set forth in the table above will vest and become payable by Company at the next month upon vesting as follows: 25% of such portion of the Total Amount of Earned Cash Bonus shall vest each six
(6) months from the Vesting Commencement Date, so that such Total Amount of Earned Cash Bonus will be fully vested on the second anniversary of the Vesting Commencement Date and fully paid to Participant at the next month upon achievement;
provided that, upon the earlier of (a) an Exit Event or (b) the Total Amount of BD Cash Payment reaches [*], the vesting and payment of such Total Amount of Earned Cash Bonus shall accelerate such that the full amount vests and
becomes immediate payable prior to the consummation of the Exit Event or at the next month following achievement if there is no Exit Event. For the purposes of this paragraph, “Vesting Commencement Date” means, as applicable, the

business development and Exit Event opportunities for the Company. 
 NOW, THEREFORE, the parties hereto, intending to be legally
bound, hereby agree as follows:

agreement executed on or after the initial closing of an Exit Event will not be deemed a BD Agreement for the purposes of calculating the BD Cash Payment and therefore does not affect the Earned Cash Bonus that Employee is eligible for. 

“BD Cash Payment” means the gross proceeds in cash received by the Company prior to the Expiration Date pursuant to the terms
of a BD Agreement. 
 “Board” means the Board of Directors of the Company. 

“Business Development Objective” means the execution and closing of a definitive BD Agreement.

thirty (30) days after receiving written notice thereof; (ii) any failure by the Employee to comply with the Company’s (or its Affiliate’s, as applicable) material written policies or rules as they may be in effect from time to
time; (iii) neglect or persistent unsatisfactory performance of the Employee’s duties and the Employee’s failure to cure such condition within thirty (30) days after receiving written notice thereof; (iv) the Employee’s
repeated failure to follow reasonable and lawful instructions from the Board or Chief Executive Officer (or the Board of Directors or Chief Executive Officer of the Company’s Affiliate, as applicable) and the Employee’s failure to cure

MISCELLANEOUS 
 4.1 Non-transferability. Except as otherwise provided in this Agreement, this Agreement, and the rights and obligations of the parties hereunder, will be binding upon and inure to the benefit of their respective
successors, assigns, heirs, executors, administrators and legal representatives. The Company may assign any of its rights and obligations under this Agreement. No other party to this Agreement may assign, whether voluntarily or by operation of law,
any of its rights and obligations under this Agreement, except with the prior written consent of the Company. 
 4.2 Withholding
Taxes. The Company or any applicable Affiliate shall be entitled, if necessary or desirable, to withhold from any amount due and payable hereunder to the Employee (or secure payment from Employee in lieu of withholding) the amount of any
withholding or other tax due with respect to the Bonus payable to the Employee under this Agreement. If desirable, the Company or Affiliate may satisfy any such tax obligation by withholding from any payment of any kind otherwise due to the
Employee. The Company shall have no liability for any tax imposed on the Employee as a result of amounts paid or payable to the Employee pursuant to this Agreement. 

4.3 Amendment of the Agreement. No modification of or amendment to this Agreement, nor any waiver of any rights under this Agreement,
shall be effective unless in writing signed by the parties to this Agreement. No delay or failure to require performance of any provision of this Agreement shall constitute a waiver of that provision as to that or any other instance. 

4.4 Severability. If one or more provisions of this Agreement are held to be unenforceable under applicable law, the parties agree to
renegotiate such provision in good faith. In the event that the parties cannot reach a mutually agreeable and enforceable replacement for such provision, then (i) such provision shall be excluded from this Agreement, (ii) the balance of
the Agreement shall be interpreted as if such provision were so excluded and (iii) the balance of the Agreement shall be enforceable in accordance with its terms.

 4.5 Titles and Headings. The headings and titles used in this Agreement are for
reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement. 
 4.6 Governing Law. The
validity, interpretation, construction and performance of this Agreement, and all acts and transactions pursuant hereto and the rights and obligations of the parties hereto shall be governed, construed and interpreted in accordance with the laws of
the state of Delaware, without giving effect to principles of conflicts of law. For purposes of litigating any dispute that may arise directly or indirectly from this Agreement, the parties hereby submit and consent to the exclusive jurisdiction of
the state of Delaware and agree that any such litigation shall be conducted only in the courts of Delaware or the federal courts of the United States located in Delaware and no other courts. 

4.7 No Obligation; Company Discretion. No provision of this Agreement or the bonus granted hereunder shall be interpreted to impose an
obligation on the Company to accept, agree to or otherwise enter into or complete any proposed or potential Exit Event or BD Agreement. The decision to enter into (or to reject) a proposed transaction to consummate an Exit Event or enter into an BD
Agreement, and all terms and conditions of such transaction, including the amount, timing and form of consideration to be provided in connection therewith, shall be within the sole and absolute discretion of the Company. In addition, this Agreement
shall not be interpreted or construed so as to limit or prevent the Company or any Affiliate from taking any actions with respect to the operation or conduct of their business or entering into any transaction that they deem appropriate or in their
best interest. 
 4.8 No Right to Continued Service. Nothing in this Agreement shall interfere with or limit in any way any right of
the Company or any of its Affiliates to terminate the Employee’s employment at any time and for any reason (or no reason), nor confer upon the Employee any right to continued service with the Company or any of its Affiliates for any period of
time or to continue such Employee’s present (or any other) rate of compensation. By accepting any payment under this Agreement, the Employee and each Person claiming under or through the Employee shall be conclusively deemed to have indicated

the Employee Retirement Income Security Act of 1974, as amended.

 4.12 Section 280G. Notwithstanding anything in this Agreement to the contrary, in the

Affiliate or any successor under Section 280G of the Code, payment of those amounts shall be contingent upon obtaining the approval of stockholders as provided in Section 280G(b)(5)(A)(ii) of the Code and the Treasury regulations
thereunder or any successor provision. In the absence of such stockholder approval in accordance with Section 280G(b)(5)(A)(ii) of the Code or any successor provision, the portion of such payments that would otherwise cause any amount to be
nondeductible under Section 280G of the Code shall be forfeited and the Employee shall have no further claim of right to such amount, except as otherwise determined by the Board.
