currently recorded on Schedule I. The failure to so record any Advance, prepayment or payment shall not limit or otherwise affect the obligation of the Company to pay any amounts due hereunder. Each request for an Advance after the date of
this Note by the Company shall be deemed a representation and warranty by the Company to the Holder as of the date of the Advance Request and the date of the Advance that (a) the Acceleration Date has not occurred and will not occur prior to or

and payable in full on the Acceleration Date without notice, demand, presentment, protest or other formalities of any kind (a) upon an Event of Default (as defined in Section 6 hereof); (b) upon the termination of the License
Agreement; or (c) upon a Change of Control Transaction (any event described in (a) – (c) above, an “Acceleration Event”). 

4.3 Prepayments; Offset. 

(a) Prepayment of Advances under the Original Note. The Company shall have the right at any time prior to the Maturity Date, and
without penalty, to prepay, in the aggregate, up to 50% of the aggregate outstanding principal amount of all Advances made under the Original Note up to such time, plus all accrued interest thereon.

at such time by reducing any amounts due and payable to the Company by the Holder pursuant to Section 8.3 or 8.4 of the Original License Agreement. 

5. Conversion. 
 5.1
Optional Conversion at Maturity or Upon Occurrence of an Acceleration Event. Not less than five (5) Business Days prior to the Maturity Date or at any time on or prior to the Acceleration Date, the Holder shall have the right to deliver
to the Company in writing a notice (the “Conversion Notice”) of its intention to convert all or a portion of the Outstanding Advanced Amount (the “Conversion Rights”) and specifying the portion of the
Outstanding Advanced Amount (the “Conversion Amount”) that shall be converted into Common Stock of the Company par value $0.0001 per share (the “Common Stock”). Any Outstanding Advance Amount not
subject to the Conversion Rights shall be repaid on the Maturity Date, or, in the case of an Acceleration Event, on the Acceleration Date. The Holder’s failure to deliver a Conversion Notice within the periods specified in the first sentence of
this Section 5.1 shall be deemed an election not to exercise the Conversion Rights. Such conversion shall take place at a conversion rate (the “Conversion Rate”) equal to four dollars and fifty four seventy third
cents ($4.5473). 
 5.2 Delivery of Note and Share Certificates. Upon conversion of this Note and repayment in full of the
Outstanding Advanced Amount pursuant to this Section 5, the Note shall be cancelled, and the Holder will deliver the original Note to the Company and execute the Company’s standard form of stock purchase agreement and/or other
agreements and instruments as are necessary or appropriate to document the issuance of the Conversion Shares upon the conversion of this Note. On, or as soon as reasonably practicable after, such conversion, the Company shall issue and deliver to
the Holder a certificate or certificates for the number of Conversion Shares to which the Holder is entitled. The Conversion Shares shall be in whole shares of Common Stock rounded down to the nearest whole share, and any fractional amount shall
continue to be an Outstanding Advance Amount. 
 6. Default. 

6.1 Event of Default. Any of the following events shall constitute an “Event of Default” hereunder: (a) the
admission in writing by the Company of its insolvency; (b) the filing of bankruptcy by the Company; (c) the execution by the Company of a general assignment for the benefit of creditors; (d) the filing by or against the Company of any petition in
bankruptcy or any petition for relief under the provisions of the federal bankruptcy act or any other state or federal law for the relief of debtors and the continuation of such petition without dismissal for a period of sixty (60) days or more; (e)
the failure of Company to perform any of its obligations under this Note, other than the failure to pay any principal or accrued interest under the terms of 

  
 4 








 
this Note when due and payable, after written notice to the Company of such alleged failure to perform and a ten (10) Business Day opportunity to cure; (f) the failure of the Company to
pay any principal or accrued interest under the terms of this Note within two (2) Business Days of the date due and payable; (g) the failure of the Company to perform any obligation under any document, instrument or agreement executed in
connection with this Note, including the License Agreement, after written notice to the Company of such alleged failure to perform and a 10-Business Day opportunity to cure; (h) the appointment of a receiver or trustee to take possession of the
property or assets of the Company; (i) any dissolution of the Company; (j) the adoption by the Company of any plan of liquidation; (k) the commencement against the Company of any case, proceeding or other action seeking issuance of a
warrant of attachment, execution, distraint or similar process against all or any substantial part of its assets which results in the entry of an order for any such relief which shall not have been vacated, discharged, or stayed or bonded pending
appeal within 60 days from the entry thereof; or (l) any challenge or contest by the Company in any action, suit or proceeding of the validity or enforceability of this Note. 

6.2 Remedies. During the continuance of an Event of Default, (a) the Holder shall have the right to (i) accelerate the
payment of the Outstanding Advanced Amount and (ii) enforce this Note by exercise of the rights and remedies granted to him, her or it by applicable law and (b) in lieu of the interest rate specified in Section 4.1, interest
shall accrue on the Outstanding Advanced Amount at a rate equal to the lesser of (x) 18% per annum and (y) the maximum rate permissible under applicable law. The Company hereby waives demand, notice, presentment, protest and
notice of dishonor. 
 6.3 Equitable Remedies. The Company stipulates that the Holder’s remedies at law in the event of any
default or threatened default by the Company in the performance of or compliance with any of the terms of this Note may not be adequate to compensate the Holder to the extent permitted by law and that such terms may be specifically enforced by a
decree for the specific performance of any agreement contained herein or by an injunction against a violation of any of the terms hereof or otherwise. 

6.4 Waiver; Cumulative Remedies. No course of dealing or any delay or failure to exercise any right hereunder on the Holder’s part
shall operate as a waiver of such right or otherwise prejudice the Holder’s rights, powers or remedies. No single or partial waiver by the Holder of any provision of this Note or of any breach or default hereunder or of any right or remedy
shall operate as a waiver of any other provision, breach, default, right or remedy or of the same provision, breach, default, right or remedy on a future occasion. The Holder’s rights and remedies are cumulative and are in addition to all
rights and remedies that the Holder may have in law or in equity or by statute or otherwise. 
 6.5 Usury. All agreements between the
Company and the Holder, whether now existing or hereafter arising and whether written or oral, are expressly limited so that in no contingency or event whatsoever, whether by acceleration of the maturity of this Note or otherwise, shall the amount
paid, or agreed to be paid, to the Holder for the use, forbearance, or detention of the money to be loaned under this Note or otherwise, exceed the maximum amount permissible under applicable law. If from any circumstances whatsoever fulfillment of
any provision of this Note or of any other document evidencing, securing, or pertaining to the indebtedness evidenced by this Note, at the time performance of such provision shall be due, 

  
 5 








 
shall involve transcending the limit of validity prescribed by law, then ipso facto, the obligation to be fulfilled shall be reduced to the limit of such validity, and if from any such
circumstances the Holder shall ever receive anything of value as interest or deemed interest by applicable law under this Note or any other document evidencing, securing, or pertaining to the indebtedness evidenced by this Note or otherwise an
amount that would exceed the highest lawful rate, such amount that would be excessive interest shall be applied to the reduction of the principal amount owing under this Note or on account of any other indebtedness of the Company to the Holder
relating to this Note, and not to the payment of interest, or if such excessive interest exceeds the unpaid balance of principal of this Note and such other indebtedness, such excess shall be refunded to the Company. In determining whether or not
the interest paid or payable with respect to any indebtedness of the Company to the Holder, under any specific contingency, exceeds the highest lawful rate, the Company and the Holder shall, to the maximum extent permitted by applicable law,
(a) characterize any non-principal payment as an expense, fee, or premium rather than as interest, (b) amortize, prorate, allocate, and spread the total amount of interest throughout the full term of such indebtedness so that the actual
rate of interest on account of such indebtedness is uniform throughout the term of such indebtedness, and/or (c) allocate interest between portions of such indebtedness, to the end that no such portion shall bear interest at a rate greater than
that permitted by law. The terms and provisions of this Section shall control and supersede every other conflicting provision of all agreements between the Company and the Holder. Each of the Company and the Holder has retained separate legal
counsel in connection with issuance of this Note. 
 7. Representations and Warranties of the Company. The Company hereby represents
and warrants to the Holder that as of the date hereof, as of the date of each Advance Request and as of the date of each Advance, except as set forth in the schedules delivered herewith: 

7.1 Organization, Good Standing and Qualification. The Company is a corporation duly organized, validly existing and in good standing

standing in each jurisdiction in which the conduct of its business or its ownership or leasing of property makes such qualification or leasing necessary except where the failure to do so would not reasonably be expected to cause a material adverse
effect on the operations, business or financial condition of the Company. 
 7.2 Authorization. The Company has full power and
authority and has taken all requisite action on the part of the Company, its officers, directors and stockholders necessary for (a) the authorization, execution and delivery of this Note, (b) the authorization of the performance of all

and any of the securityholders of the Company relating to the securities of the Company held by them. Except as set forth on Schedule 7.3, no person has the right to require the Company to register any securities of the Company under the
Securities Act, whether on a demand basis or in connection with the registration of securities of the Company for its own account or for the account of any other person. 

7.4 Valid Issuance. This Note has been duly and validly authorized. Upon the due conversion of this Note, the Conversion Shares will be

7.5 Consents. The execution, delivery and performance by the Company of this Note requires no consent of, action by or in respect of,
or filing with, any person, governmental body, agency, or official other than such filings as shall have been made prior to and shall be effective on and as of the date hereof and such filings required to be made after the date hereof pursuant to
applicable state and federal securities laws which the Company undertakes to file within the applicable time periods. The Company has taken all action necessary to exempt from the registration requirements of the applicable state and federal
securities laws the issuance of the Conversion Shares upon due conversion of this Note. 
 7.6 No Conflict, Breach, Violation or
Default. The execution, delivery and performance of this Note by the Company and the issuance and sale of the Conversion Shares will not conflict with or result in a breach or violation of any of the terms and provisions of, or constitute a
default under (i) the Company’s certificate of formation or the Company’s bylaws, both as in effect on the date hereof, (ii) any statute, rule, regulation or order of any governmental agency or body or any court, domestic or
foreign, having jurisdiction over the Company or any of its assets or properties or (iii) any agreement or instrument to which the Company is a party or by which the Company is bound.

9. Severability. If any provision of this Note is determined to be invalid, illegal or unenforceable, in whole or in part, the
validity, legality and enforceability of any of the remaining provisions or portions of this Note shall not in any way be affected or impaired thereby.

15. Governing Law; Consent to Jurisdiction; Waiver of Jury Trial. The validity, meaning and effect of this Note shall be determined in
accordance with the laws of the State of New York, without regard to principles of conflicts of law. The Company and the Holder each irrevocably submits to the exclusive jurisdiction of the courts of the State of New York located in New York City,
New York and the United States District Court for the Southern District of New York for the purpose of any suit, action, proceeding or judgment relating to or arising out of this Note and the transactions contemplated hereby. Service of process in
connection with any such suit, action or proceeding may be served on each party hereto anywhere in the world by the same methods as are specified for the giving of notices under this Note. The Company and the Holder each irrevocably waives any
objection to the laying of venue of any such suit, action or proceeding brought in such courts and irrevocably waives any claim that any such suit, action or proceeding brought in any such court has been brought in an inconvenient forum. EACH OF THE
COMPANY AND THE HOLDER HEREBY WAIVES ANY RIGHT TO REQUEST A TRIAL BY JURY IN ANY LITIGATION WITH RESPECT TO THIS NOTE AND REPRESENTS THAT COUNSEL HAS BEEN CONSULTED SPECIFICALLY AS TO THIS WAIVER.

 16. Right of Offset. Without limiting any of the Holder’s other rights or remedies
hereunder or otherwise, the Company hereby acknowledges and agrees that the Holder shall have the right to reduce any amount payable by the Holder to the Company pursuant to the License Agreement by any amount owed by the Company and not timely paid
to the Holder in accordance with the terms of this Note. 
 17. Taxes. Any and all payments by or on account of any obligation of the
Company under this Note shall be made without deduction or withholding for any taxes; provided, however, if the Holder transfers the Note to a non-U.S. person or Affiliate (a “non-U.S. Transferee”), the Company shall deduct
and withhold from payments due to such non-U.S. Transferee pursuant to this Note any taxes required to be deducted and withheld under applicable law. Any such withheld taxes shall be timely paid over to the appropriate governmental authority in
accordance with applicable law. To the extent that taxes are deducted and withheld from payments otherwise payable to a non-U.S. Transferee pursuant to this Note, and are paid to the appropriate governmental authority, such deducted and withheld
amounts shall be treated for all purposes of this Note as having been paid to the person in respect of whom such deduction and withholding was made. The Company shall provide such non-U.S. Transferee with proof reasonably satisfactory to such
non-U.S. Transferee of any taxes withheld and paid to any governmental authority on behalf of such non-U.S. Transferee. If a payment is payable (in whole or in part) in consideration other than cash to a non-U.S. Transferee pursuant to this Note,
including upon a conversion pursuant to Section 5, and if the cash portion of any such payment is insufficient to satisfy all required tax withholding obligations, the Company shall retain an amount of the non-cash consideration
otherwise payable or deliverable to such non-U.S. Transferee equal in value to the amount required to satisfy any applicable withholding taxes (as reasonably determined by the Company in good faith). On or prior to the date hereof, the Holder shall
deliver to the Company two executed originals of IRS Form W-9 certifying that the Holder is not subject to U.S. federal backup withholding. As soon as reasonably practicable following any transfer by the Holder of the Note to a non-U.S. Transferee,
such non-U.S. Transferee shall deliver to the Company (i) two executed originals of the applicable IRS Form W-8, and (ii) to the extent such non-U.S. Transferee is eligible for an exemption from or reduction of any otherwise applicable
withholding tax, any other applicable documentation required or reasonably requested by the Company to establish that such non-U.S. Transferee is entitled to such exemption or reduction. Any non-U.S. Transferee and the Company shall use commercially
reasonable efforts to establish any applicable exemption from or reduction of otherwise applicable withholding taxes with respect to payments made hereunder. If any payment hereunder to a non-U.S. Transferee is subject to Sections 1471-1474 of the
U.S. Internal Revenue Code (“FATCA”), the applicable non-U.S. Transferee shall provide the Company with all documentation prescribed by applicable law or reasonably requested by the Company in order for the Company to comply
with its obligations under, and determine the amount, if any, of withholding taxes imposed pursuant to FATCA.
