	[    ] Shares of Voting Common Stock	  	No. [    ] WARRANT

 This WARRANT (this “Warrant”) is issued as of August 4, 2020 (the “Initial
Issuance Date”), by ATHENEX, INC., a Delaware corporation (the “Company”), to [    ] (“Purchaser” and, together with any
assignee(s) or transferee(s), “Holder” or “Holders”). 
 WHEREAS, the Purchaser has become a lender
under that certain Credit Agreement and Guaranty, dated as of June 19, 2020 (the “Credit Agreement”) by and among the Company, Oaktree Fund Administration, LLC as administrative agent and the other lenders from time to time
party thereto pursuant to that certain Assignment and Assumption Agreement dated as of August 4, 2020 by and among the Purchaser, the Company, the affiliates of Oaktree Capital Management, L.P. party thereto as assignors, and the other
assignees party thereto (the “Assignment and Assumption”); 
 WHEREAS, pursuant to the Credit Agreement, the Company
may borrow from the lenders thereunder, and such lenders may loan to the Company, up to $225,000,000 from the date of the Credit Agreement through the Maturity Date; and 

WHEREAS, the Company is issuing this Warrant to Purchaser in consideration of the Purchaser becoming a lender under the Credit
Agreement pursuant to the Assignment and Assumption. 
 NOW THEREFORE, for good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the Company and Purchaser agree as follows: 
 Section 1. Definitions.
Unless otherwise defined herein, capitalized terms have the meanings set forth in the Credit Agreement (as in effect on the date hereof), however, the following terms when used herein have the following meanings: 

“Aggregate Exercise Price” means, in connection with any Exercise of this Warrant pursuant to Section 4
(whether in whole or in part), an amount equal to the product of (i) the number of Underlying Shares in respect of which this Warrant is then being exercised pursuant to such Section 4, multiplied by (ii) the
Exercise Price. 

 “Fair Market Value” means, with respect to any security or other property,
the fair market value of such security or other property as determined by the independent members of the Board of Directors of the Company, acting in good faith. If the Holder objects in writing to the Board of Directors’ calculation of Fair
Market Value within ten (10) days of receipt of written notice thereof and the Holder and the Company are unable to agree on Fair Market Value during the five (5) day period following the delivery of the Holder’s objection, the
valuation dispute resolution procedure set forth in Section 22 hereof shall be invoked to determine Fair Market Value. 

“Market Price” means, with respect to a particular security, on any given day, the last reported sale price, regular way, or,
in case no such reported sale takes place on such day, the average of the closing bid and asked prices, regular way, in either case on the principal national securities exchange on which the applicable securities are listed or admitted to trading,
or if not listed or admitted to trading on any national securities exchange, the last quoted bid price in the over-the-counter market as reported by Pink Sheets LLC or
similar organization. “Market Price” shall be determined without reference to after hours or extended hours trading. If such security is not listed and traded in a manner that the quotations referred to above are available for the period
required hereunder, the Market Price per share of Voting Common Stock shall be deemed to be the fair market value per share of such security as determined in good faith by the independent members of the Board of Directors in reliance upon an opinion
of an accounting firm of nationally recognized standing retained by the Company for this purpose and reasonably acceptable to the Holder (or if there is more than one Holder, a majority in interest of Holders excluding any Holder that is an
Affiliate of the Company). For the purposes of determining the Market Price of the Voting Common Stock on the Trading Day preceding, on or following the occurrence of an event, (i) that Trading Day shall be deemed to commence immediately after
the regular scheduled closing time of trading on the Trading Market on which the Voting Common Stock is listed or, if trading is closed at an earlier time, such earlier time and (ii) that Trading Day shall end at the next regular scheduled
closing time, or if trading is closed at an earlier time, such earlier time (for the avoidance of doubt, and as an example, if the Market Price is to be determined as of the last Trading Day preceding a specified event and the closing time of
trading on a particular day is 4:00 p.m. and the specified event occurs at 5:00 p.m. on that day, the Market Price would be determined by reference to such 4:00 p.m. closing price). 

“Trading Day” means a day on which the Voting Common Stock is traded on a Trading Market or, if the Voting Common Stock is
not traded on a Trading Market, then on the principal securities exchange or securities market on which the Voting Common Stock is then traded. 

“Trading Market” means any market or exchange of The Nasdaq Stock Market LLC or the New York Stock Exchange. 

“VWAP” means, for any date, the price determined by the first of the following clauses that applies: (i) if the Voting
Common Stock is then listed or quoted on a Trading Market, the daily volume weighted average price of the Voting Common Stock for such date (or the nearest preceding date) on the Trading Market on which the Voting Common Stock is then listed or

  
 -2- 

 
quoted as reported by Bloomberg L.P. (based on a Trading day from 9:30 a.m. (New York City time) to 4:00 pm (New York City time)), (ii) if the Voting Common Stock is not then listed on a Trading
Market or quoted for trading on the OTC Bulletin Board and if prices for the Voting Common Stock are then reported in the “Pink Sheets” published by OTC Markets Group Inc. (or a similar organization or agency succeeding to its functions of
reporting prices), the most recent bid price per share of the Voting Common Stock so reported or (iii) in all other cases, the fair market value of a share of Voting Common Stock as determined by an independent nationally recognized investment
banking, accounting or valuation firm selected in good faith by the Company and reasonably acceptable to the Holder, the fees and expenses of which shall be paid by the Company. 

Section 2. Issuance of Warrant; Term. For good and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the Company hereby grants to Holder the right to purchase from the Company [ ] fully paid and nonassessable shares of the Company’s voting common stock having a par value $0.001 per share (the “Voting
Common Stock”). The shares of Voting Common Stock issuable upon exercise of this Warrant are hereinafter referred to as the “Underlying Shares.” This Warrant shall be exercisable at any time and from
time to time, in whole or in part, during the period commencing on the date hereof and ending at 12:00 a.m. Eastern Time on June 19, 2027 (such date and time, the “Expiration Date”). 

Section 3. Exercise Price. The exercise price per share of Voting Common Stock for which each Underlying Share may be
purchased pursuant to this Warrant shall be $12.63 (the “Exercise Price”), subject to adjustment pursuant to Section 7 hereof. 

Section 4. Exercise. 

(a) This Warrant may be exercised by the Holder hereof as to all or any portion of the Underlying Shares, upon delivery of written notice to
the Company, together with this original Warrant and (x) payment to the Company of the Aggregate Exercise Price or (y) instruction to the Company to withhold a number of the Underlying Shares then issuable upon exercise of this Warrant
with an aggregate value (determined on the basis of the average Market Price per share for the Voting Common Stock on the last five Trading Days for such stock immediately prior to the Exercise Date, as defined below) equal to (as nearly as possible
without being less than) such Aggregate Exercise Price (collectively, the “Exercise”, with the date of an Exercise being an “Exercise Date”). The Exercise Price (if paid pursuant to clause (x) above) shall be
payable by delivery by the Holder of a certified or official bank check payable to the order of the Company or wire transfer of immediately available funds to an account designated by the Company. This Warrant shall be deemed to have been so
exercised as of the applicable Exercise Date, and the Holder shall be entitled to receive the Underlying Shares issuable upon such Exercise and be treated for all purposes as the holder of record of the Underlying Shares as of such date. Upon the
Exercise of this Warrant, the Company shall, within two (2) Business Days of the Exercise Date (the “Underlying Share Delivery Date”), execute and deliver to the Holder of this Warrant (a) a statement confirming the total
number of Underlying Shares for which this Warrant is being exercised, and (b) (i) if the Underlying Shares are issued in certificate form, a certificate or 

  
 -3- 

 
certificates for the number of Underlying Shares issuable upon such Exercise, or (ii) if the Underlying Shares are issued in uncertificated form, a written confirmation evidencing the
book-entry registration of such Underlying Shares in the Holder’s name; provided that if the Company fails to deliver to Holder such certificate or certificates (in the case of Underlying Shares issued in certificate form) or written
confirmation (in the case of Underlying Shares issued in uncertificated form) by the Underlying Share Delivery Date, the Holder will have the right to rescind such Exercise. Any rescission by the Holder pursuant to this
Section 4(a) shall not affect any other remedies available to the Holder under applicable law or equity or pursuant to Section 15 hereof as a result of the Company’s failure to timely deliver
the Underlying Shares. If this Warrant shall be exercised with respect to less than all of the Underlying Shares, the Company shall deliver a new Warrant covering the number of Underlying Shares in respect of which this Warrant shall not have been
exercised, which new Warrant shall in all other respects be identical to this Warrant. The Company covenants and agrees that it will pay when due any and all state and federal issue taxes which may be payable in respect of the issuance of this
Warrant or the issuance of any Underlying Shares upon exercise. 
 (b) In the event of any withholding of shares of Underlying Shares
pursuant to Section 4(a)(y) above where the aggregate number of Underlying Shares equal to (as nearly as possible without being less than) the Aggregate Exercise Price is not a whole number, the number of the Underlying
Shares withheld by or surrendered to the Company shall be rounded up to the nearest whole share, and the Company shall make a cash payment to the Holder (by delivery of a certified or official bank check or by wire transfer of immediately available
funds) based on the incremental fraction of Underlying Shares being so withheld by or surrendered to the Company in an amount equal to the product of (x) such incremental fraction of Underlying Shares being so withheld or surrendered multiplied
by (y) the value per share of Underlying Shares (determined on the basis of the Market Price per share for the Voting Common Stock immediately prior to the applicable Exercise). 

(c) The Company shall not knowingly effect the exercise of this Warrant, and the Holder shall not have the right to exercise this Warrant to
the extent that, after giving effect to such exercise, the Holder (together with such Person’s Affiliates) would beneficially own in excess of 9.99% (the “Maximum Percentage”) of the Voting Common Stock outstanding immediately
after giving effect to such exercise. For purposes of the foregoing sentence, the aggregate number of shares of Voting Common Stock beneficially owned by such Person and its Affiliates shall include the number of shares of Voting Common Stock
issuable upon exercise of this Warrant with respect to which the determination of such sentence is being made, but shall exclude shares of Voting Common Stock which would be issuable upon (i) exercise of the remaining, unexercised portion of
this Warrant beneficially owned by such Person and its Affiliates and (ii) exercise or conversion of the unexercised or unconverted portion of any other securities of the Company beneficially owned by such Person and its Affiliates (including,
without limitation, any convertible notes or convertible shares or warrants) subject to a limitation on conversion or exercise analogous to the limitation contained herein. Except as set forth in the preceding sentence, for purposes of this
paragraph, beneficial ownership shall be calculated in accordance with Section 13(d) of the Exchange Act. For purposes of this Warrant, in determining the number of outstanding shares of 

  
 -4- 

 
Voting Common Stock, a Holder of this Warrant may rely on the number of outstanding shares of Voting Common Stock as reflected in the most recent of (1) the Company’s Form 10-K, Form 10-Q or other public filing with the Securities and Exchange Commission, as the case may be, (2) a more recent public announcement by the Company or
(3) any other notice by the Company or its transfer agent setting forth the number of shares of Voting Common Stock outstanding. Upon the written or oral request of a Holder, the Company shall, within five (5) Business Days, confirm to
such Holder the number of shares of its Voting Common Stock then outstanding. Furthermore, upon the written or oral request of the Company, a Holder shall confirm to the Company its then current beneficial ownership with respect to the
Company’s Voting Common Stock. 
 Section 5. No Fractional Shares. No fractional shares may be issued upon any
exercise of this Warrant or as a consequence of any adjustment pursuant to Section 7, and any fractions shall be rounded upwards to the nearest whole number of shares. If upon any exercise or adjustment of this Warrant a
fraction of a share results, the Company will pay to the Holder the cash value of any such fractional share, calculated on the basis of the Exercise Price. 

Section 6. Securities Laws. 

(a) Holder acknowledges that the Underlying Shares are being offered and sold by the Company in accordance with Regulation D under the
Securities Act and that the Underlying Shares will constitute “restricted securities” as defined in Rule 144 under the Securities Act. Neither this Warrant nor the Underlying Shares have been registered under the Securities Act, or any
state securities laws (“Blue Sky Laws”). This Warrant has been acquired for the Holder’s own account for investment purposes and not with a current view to distribution or resale and may not be sold or otherwise transferred
(i) without an effective registration statement for such Warrant under the Securities Act and such applicable Blue Sky Laws, or (ii) unless Holder shall have delivered to the Company an opinion of counsel to the effect that the Warrant or
such portion of the Warrant to be sold or transferred may be sold or transferred under an exemption from such registration. 
 (b) The
Company covenants and agrees that all Underlying Shares will, upon issuance and payment therefor, be legally and validly issued and outstanding, free from all taxes, liens, charges and preemptive or similar rights, if any, with respect thereto or to
the issuance thereof. The Company will take all such action as may be reasonably necessary or appropriate to assure that the Underlying Shares may be issued as provided herein without violating any applicable law or regulation, or any requirements
of the Trading Market upon which the Voting Common Stock may be listed. 
 (c) The certificates representing the Underlying Shares will bear
the following or similar legend, unless the Company determines otherwise in compliance with applicable law: 
 “THE SHARES OF COMMON
STOCK REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE US SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”) AND MAY NOT BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED EXCEPT (1) IN AN OFFSHORE TRANSACTION
MEETING 

  
 -5- 

 
THE REQUIREMENTS OF RULE 903 OR RULE 904 OF REGULATION S UNDER THE SECURITIES ACT, (2) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT, OR (3) PURSUANT TO AN
AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT, IN EACH CASE IN ACCORDANCE WITH ALL APPLICABLE SECURITIES LAWS.” 

Section 7. Anti-Dilution Adjustments. 

(a) If the Company shall at any time prior to the expiration of this Warrant (i) pay a stock dividend or otherwise make a distribution or
distributions on shares of Voting Common Stock or any other equity or equity securities, (ii) subdivide the Voting Common Stock (by stock split, recapitalization, or any other similar event) into a larger number of shares, (iii) combine
the Voting Common Stock (by stock split or reverse stock split, recapitalization, combination of shares, or any other similar event) or (iv) issue by reclassification of shares of Voting Common Stock any shares of capital stock of the Company
(with the exception of any reclassification that constitutes a Fundamental Change, as hereinafter defined), then in each such case the Exercise Price shall be adjusted by multiplying the Exercise Price in effect immediately prior to (x) the
record date for the determination of stockholders entitled to receive such dividend or distribution or (y) the effective date in the case of a subdivision, combination or re-classification by a fraction,
the numerator of which shall be the number of shares of Voting Common Stock outstanding immediately before such event and the denominator of which shall be the number of shares of Voting Common Stock outstanding immediately after such event, and the
number of shares issuable upon exercise of this Warrant shall be proportionately adjusted such that the Aggregate Exercise Price shall remain unchanged. Before taking any action which would result in an adjustment in the number of Underlying Shares
for which this Warrant is exercisable or to the Exercise Price, the Company shall obtain all such authorizations or exemptions thereof, or consents thereto, as may be necessary from any public regulatory body or bodies having jurisdiction thereof.

 (b) If the Company shall at any time prior to the expiration of this Warrant (in each case, occurring after the date hereof) be a party
to any merger, consolidation, exchange of shares of Voting Common Stock, sale of a majority of the Voting Common Stock, sale of all or substantially all of the assets of the Company, separation, reorganization, recapitalization, winding up or
liquidation of the Company, or other similar event or transaction (each, a “Fundamental Change”), as a result of which shares of Voting Common Stock shall be changed into the same or a different number or class or classes of
securities of the Company or another entity, or the holders of shares of Voting Common Stock are entitled to receive cash or other property, then, upon the Exercise of this Warrant by the Holder, such Holder shall receive, for the Aggregate Exercise
Price as in effect immediately prior to such Fundamental Change (subject to all other adjustments under this Warrant), the aggregate number of shares or such other securities, cash or other property which such Holder would have received if this
Warrant had been exercised immediately prior to such Fundamental Change (collectively, the “Fundamental Change Receivable”), which, upon the Holder’s election, may be received net of the Aggregate Exercise Price (for the
avoidance of doubt, without payment by the Holder of any cash in an amount equal to the then Exercise Price). In the 

  
 -6- 

 
case of any Fundamental Change, the successor or purchasing party of such merger, consolidation, exchange of shares of Voting Common Stock, sale of all or substantially all of the Assets of the
Company or reorganization (if other than the Company) shall duly execute and deliver to the Holder a supplement to this Warrant acknowledging the Company and such party’s obligations under this Section 7(b). The terms of this
Warrant shall be applicable to the Fundamental Change Receivable due to the Holder upon the consummation of any such Fundamental Change. 

(c) If the Company, at any time while this Warrant is outstanding, shall otherwise distribute to all holders of Voting Common Stock (and not
to the Holder or Holders) evidences of its indebtedness or assets (including cash and cash dividends) or rights or warrants to subscribe for or purchase any security (for the avoidance of doubt, excluding in each such case any Fundamental Change
Receivable), then in each such case the Exercise Price shall be adjusted by multiplying the Exercise Price in effect immediately prior to the record date fixed for determination of stockholders entitled to receive such distribution by a fraction,
the numerator of which shall be such VWAP on such record date less the then Fair Market Value at such record date of the portion of such assets or evidence of indebtedness so distributed applicable to one outstanding share of Voting Common Stock,
and the denominator of which shall be the VWAP determined as of the record date mentioned above. Such adjustment shall be made whenever any such distribution is made and shall become effective immediately after the record date mentioned above. 

(d) Not less than five (5) days prior to the record date or effective date, as the case may be, of any event which requires or might
require an adjustment or readjustment pursuant to Section 7(a) or Section 7(c) (each, an “Adjustment Event”), and not less than ten (10) days prior to the record date or effective date, as the case may be, of
any Fundamental Change, the Company shall give written notice of such Adjustment Event or Fundamental Change (as applicable) to the Holder or Holders, describing such Adjustment Event or Fundamental Change in reasonable detail and specifying the
record date or effective date, as the case may be. Such notice shall additionally include the Company’s certification of the following computations, as applicable, each of which shall have been made by the Company in good faith: (i) in the
case of an Adjustment Event, if determinable, the required adjustment and the computation thereof or, if the required adjustment is not determinable at the time of such notice, the Company shall give notice to the Holder or Holders of such
adjustment and computation promptly after such adjustment becomes determinable, and (ii) in the case of a Fundamental Change, the number of shares or such other securities, cash or other property which is payable to the Holder or Holders upon
the Fundamental Change, the computation thereof, and the computation of the then applicable Exercise Price. Except as otherwise prohibited by applicable laws, to the extent that any notice provided pursuant to this Section 7(d) contains
material, non-public information regarding the Company, the Company shall disclose such information regarding the Company in a Current Report on Form 8-K and file such
Current Report on Form 8-K with the SEC no later than the second Trading Day following the date such notice is delivered to the Holder. 

(e) Notwithstanding any other provision hereof, if an exercise of all or any portion of this Warrant is to be made in connection with a
Fundamental Change or a public offering, such exercise may, at the election of the Holder, be conditioned upon the consummation of such transaction, in which case such exercise shall not be deemed to be effective until immediately prior to the
consummation of such transaction. 

  
 -7- 

 (f) At all times on and prior to the Expiration Date, the Company shall at all times reserve
and keep available out of its authorized but unissued Voting Common Stock (or other equity interests then constituting Underlying Shares), solely for the purpose of issuance upon the exercise of this Warrant, the maximum number of Underlying Shares
issuable upon the exercise of this Warrant. The Company further covenants that its issuance of this Warrant shall constitute full authority to its officers who are charged with the duty of executing stock certificates or effectuating the book entry
of uncertificated shares to execute and issue, or enter, the necessary certificates or book entries (as applicable) for the Underlying Shares upon the exercise of the purchase rights under this Warrant. The Company shall not increase the par value
of any Underlying Shares receivable upon the exercise of this Warrant above the Exercise Price then in effect, and shall take all such actions within its power as may be necessary or appropriate in order that the Company may validly and legally
issue fully paid and non-assessable Underlying Shares upon the exercise of this Warrant. 

Section 8. Transfer of Warrant. Subject to compliance with applicable federal and state securities laws, the Holder may,
from time to time, transfer this Warrant or the Underlying Shares, in each case, in whole or in part, by giving the Company a written notice of the portion of the Warrant or the shares of the Underlying Shares being transferred, such notice to set
forth the name, address and taxpayer identification number of the transferee, the anticipated date of such transfer, and surrendering this Warrant or the certificates or book-entry records representing shares of the Underlying Shares, as applicable,
to the Company for reissuance to the transferee(s). Upon surrender of this Warrant by a Holder to the Company for transfer, in whole or in part, the Company shall issue a new warrant to such Holder in such denomination as shall be requested by such
Holder covering the number of Underlying Shares, if any, in respect of which this Warrant shall not have been transferred. Such new warrant shall be identical in all other respects to this Warrant. This Warrant may be divided or combined with other
Warrants upon presentation hereof at the office of the Company, together with a written notice specifying the names and denominations in which new Warrants are to be issued, signed by the Holder or its agent or attorney. Subject to compliance with
this Section 8 as to any transfer which may be involved in such division or combination, the Company shall execute and deliver a new Warrant or Warrants in exchange for the Warrant or Warrants to be divided or combined in
accordance with such notice. All Warrants issued on transfers or exchanges shall be dated as of the Initial Issuance Date and shall be identical with this Warrant except as to the number of Underlying Shares issuable pursuant thereto. 

Section 9. No Impairment. The Company may not, including, without limitation, by amendment of its certificate of
incorporation or bylaws, or through a Fundamental Change or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Warrant, and the Company shall at all times in good faith assist in the carrying
out of all such terms and in the taking of all such action as may be necessary or appropriate in order to protect the rights of the Holder or Holders against impairment. Without limiting the generality of

  
 -8- 

 
the foregoing, the Company shall take (a) all such action as may be necessary or appropriate in order that the Company may duly and validly issue fully paid and non-assessable Underlying Shares, free from any taxes, liens, charges and preemptive rights, upon the exercise of this Warrant, and (b) use its best efforts to obtain all such authorizations, exemptions or
consents from any public regulatory body having jurisdiction thereof, as may be necessary to enable the Company to perform its obligations under this Warrant. 

Section 10. No Rights or Liabilities as a Stockholder. This Warrant shall not entitle the Holder or Holders hereof to any
voting rights or other rights as a stockholder of the Company with respect to the Underlying Shares prior to the exercise of the Warrant. No provision of this Warrant, in the absence of affirmative action by the Holder or Holders to purchase the
Underlying Shares, and no mere enumeration herein of the rights or privileges of the Holder or Holders, shall give rise to any liability of such Holder or Holders for the Exercise Price or as a stockholder of the Company, whether such liability is
asserted by the Company or by creditors of the Company. 
 Section 11. Representations and Warranties of the Company. The
Company hereby represents and warrants: 
 (a) As of the Initial Issuance Date, the Company (A) is a corporation duly organized,
validly existing and in good standing under the laws of the State of Delaware, (B) has all requisite power and authority to own and operate its properties, to carry on its business as now conducted and as currently proposed to be conducted, to
issue and enter into the Warrant and to carry out the transactions contemplated thereby, and (C) except where the failure to do so, individually or in the aggregate, has not had, and could not be reasonably expected to have, a material adverse
effect on the business, assets, financial condition or operations of the Company, is qualified to do business and, where applicable is in good standing, in every jurisdiction where such qualification is required. 

(b) This Warrant is, and any Warrant issued in substitution for or replacement of this Warrant (including pursuant to
Section 16) shall be, upon issuance, duly authorized and validly issued. This Warrant constitutes, and any Warrant issued in substitution for or replacement of this Warrant shall be, upon issuance, a legal,
valid and binding obligation of the Company, enforceable against the Company in accordance with its terms, except as enforceability may be limited by applicable bankruptcy, insolvency or other similar laws affecting the enforcement of
creditors’ rights generally and by general principles of equity. 
 (c) As of the Initial Issuance Date, the execution, delivery and
performance by the Company of the Warrant does not and will not (A) violate any material provision of applicable law or the organizational documents of the Company, (B) conflict with, result in a breach of, or constitute (with the giving
of any notice, the passage of time, or both) a default under any material agreement of the Company or (C) result in or require the creation or imposition of any lien upon any assets of the Company.

behalf of such IMCO Clients.] 
 Section 14. Survival. The rights of the Holder or Holders under this Warrant, and the
covenants and agreements of the Company set forth in this Warrant for the benefit of the Holder or Holders, shall survive exercise of all or any portion of this Warrant and shall inure to the Holder or Holders of any Underlying Shares. 

Section 15. Remedies. If the Company violates, breaches or defaults under this Warrant, the Holder may proceed to protect

Initial Issuance Date, the Purchaser shall provide the Company with a valuation of the Warrant for tax purposes (the “Proposed Valuation”). If the Company disagrees with the Proposed Valuation, it shall propose reasonable

Neither the execution and delivery of this Agreement or any other Transaction Document to which Purchaser is a party nor the performance or
consummation of the transactions contemplated hereby or thereby will: (a) contravene, conflict with, result in a breach or violation of, constitute a default under, or accelerate the performance provided by, in any material respects any

Section 5.01 Access; Information. 

(a) License Notices. Subject to any applicable confidentiality restrictions, the Company shall promptly provide Purchaser with copies of
any written notices of material breach or default received or given by the Company under any Material Contract, and to the extent the Company is barred from providing Purchaser with copies of such notices due to any applicable confidentiality
restrictions, the Company shall inform Purchaser of the existence of such notice. The Company shall promptly notify Purchaser of any breaches or alleged breaches under any Material Contracts and of any other events with respect to any Material
Contract or the subject matter thereof which would reasonably be expected to have a Material Adverse Effect. 

  
 40

(i) any action, suit, claim, cause of action, proceeding or investigation pending or, to the Knowledge of the Company, threatened in writing against the Company or its Subsidiaries, or (ii) proceeding or inquiry of any Governmental
Authority pending or, to the Knowledge of the Company, threatened in writing against the Company, in each case that is related to any Material Contract, the Product, the Material Patents or any Transaction Document, in each case, that would
reasonably be expected to result in a Material Adverse Effect. 
 (c) Maintenance of Books and Records. The Company shall keep and
maintain, or cause to be kept and maintained, at all times full and accurate books of account and records adequate to correctly reflect all payments paid and/or payable with respect to the Included Product Revenues and Assigned Interests for three
(3) years from the year of creation of such records. 
 (d) Inspection Rights. Purchaser shall have the right to designate a
Third Party independent public accounting firm (the “Purchaser Representative”) to visit the Company and its Subsidiaries’ offices and properties where the Company and its Subsidiaries keep and maintain their books and records
relating or pertaining to the Included Product Revenues, the Assigned Interests and the Revenue Interest Payments payable hereunder for purposes of conducting an audit of such books and records, and to inspect and audit such books and records. Any
such audit or inspection must (i) be limited to the three-year period during which the Company is required to maintain such records, (ii) not be exercised more than once in any calendar year, (iii) during normal business hours, and
(iv) following seven (7) Business Days’ prior written notice given by Purchaser to the Company; provided that clauses (ii), (iii) and (iv) above shall not apply if a Put Option Event has occurred and is continuing. In connection
with any such audit, the Company will provide such Purchaser’s Representative reasonable access to such books and records maintained by Company, and shall permit the Purchaser Representatives to discuss the business, operations, properties and
financial and other condition of the Company or any of its Subsidiaries including, but not limited to, matters relating or pertaining to the Included Product Revenues, the Assigned Interests and the Revenue Interest Payments payable hereunder with
officers of the Company and with the Company’s independent certified public accountants, in all cases solely to verify the accuracy of the Quarterly Reports provided under Section 5.01(f) and related payments due under this Agreement.
Without limiting the foregoing, prior to any audit under this Section, the Purchaser Representative shall enter into a written confidentiality agreement with Company that (A) limits the use of the Company’s records to the verification
purpose described in this Section; (B) limits the information that the Purchaser Representative may disclose to Purchaser to information required for Purchaser to understand the payments due and paid and any discrepancies; and
(C) prohibits the disclosure of any information contained in such records to any other Third Party for any purpose. The Parties agree that all information subject to review under Section 5.01(d) or provided by the Purchaser’s
Representative to Company is Company’s Confidential Information, and Purchaser shall not use any such information for any purpose that is not germane to this Section 5.01(d). 

(e) Resolution; Audit Costs. Any audit under Section 5.01(d) shall be at Purchaser’s expense; provided, however, in the event
that as a result of any audit of the books and records of the Company and its Subsidiaries reveals that the amounts paid to Purchaser hereunder for the period of such audit have been understated by more than five percent (5%) of the amounts
determined to be due for the period subject to such audit, then the Company shall reimburse reasonable audit fees for a given audit. Any overpayment made by the Company shall be promptly refunded or fully creditable against amounts payable in
subsequent payment periods, at the Company’s election

certifying that to the Knowledge of the Company (i) such Quarterly Report is a true and complete copy and (ii) any statements and any data and information therein prepared by the Company are true, correct and accurate in all material
respects. The Company shall use, and shall ensure that each of its Affiliates shall use, Commercially Reasonable Efforts to include in each contract of the Company for the Development or Commercialization of the Product entered into on or after the
Effective Date, obligations reasonably appropriate to ensure that the counterparty to such contract shall furnish to the Company all information necessary for the Company to comply with this Section 5.01(f) and calculate the Included Product
Revenue as set forth in this Agreement. 
 (g) Periodic Reports. The Company shall deliver to Purchaser the following financial
statements:

of the Company and its Subsidiaries for such Fiscal Quarter; and 
 (ii) Within ninety (90) days after the end of each
Fiscal Year, copies of the audited consolidated financial statements of the Company and its Subsidiaries for such Fiscal Year. 
 It is understood and
agreed that documents required to be delivered pursuant to this Section 5.01(g) shall be deemed delivered on the date that such documents are publicly available on “EDGAR.” 

Section 5.02 Material Contracts. 

The Company shall, and shall cause its Subsidiaries to, comply with all material terms and conditions of and fulfill all of its obligations
under all the Material Contracts, except for such noncompliance which would not reasonably be expected to give rise to a Material Adverse Effect. 

Section 5.03 Public Announcement. 

Except as required by law or any Governmental Authority (including the Securities and Exchange Commission) or except with the prior written
consent of the other party (which consent shall not be unreasonably withheld), no party shall issue any press release or make any other public disclosure with respect to the transactions contemplated by this Agreement or any other Transaction
Document; provided, however, that the Company and Purchaser may jointly prepare 

  
 42 

 
a press release for dissemination promptly following the Effective Date and the Funding Date and the Company may file a current report on Form 8-K (or any
other public announcement using substantially the same text as the press release or Form 8-K) with respect to the transactions contemplated by this Agreement. 

Section 5.04 Efforts; Further Assurance. 

(a) Subject to the terms and conditions of this Agreement, Purchaser and the Company agree to execute and deliver such other documents,
certificates, agreements and other writings (including any financing statement filings requested by Purchaser) and to take such other actions as may be reasonably necessary in order to consummate or implement expeditiously the transactions
contemplated by this Agreement and any other Transaction Document and to vest in Purchaser good, valid and marketable rights and interests in and to the Assigned Interests free and clear of all Liens, except for Permitted Liens. 

(b) Purchaser and the Company shall cooperate and provide assistance as reasonably requested by the other party in connection with any Third
Party litigation, arbitration or other Third Party proceeding (whether threatened, existing, initiated, or contemplated prior to, on or after the date hereof) to which any party hereto or any of its officers, directors, shareholders, agents or
employees is or may become a party or is or may become otherwise directly or indirectly affected or as to which any such Persons have a direct or indirect interests, in each case relating to this Agreement, any other Transaction Document, the
Assigned Interests or any other Collateral, or the transactions described herein or therein. 
 Section 5.05 Put Option; Call Option.

 (a) Put Option. 

(i) In the event that a Put Option Event shall occur at any time during the period from the Funding Date to and including the
end of the Term, Purchaser shall have the right, but not the obligation (the “Put Option”), exercisable within sixty (60) days after the earlier of the occurrence of a Put Option Event or Purchaser’s receipt of written
notice from the Company of a Put Option Event (a “Put Option Trigger”) to require the Company to repurchase from Purchaser the Assigned Interests at the Put/Call Price; provided that during the occurrence and continuation of
(x) a Bankruptcy Event or (y) a Put Option Event described in clause (d)(i) of the definition thereof, the Put Option shall, in each case, be exercisable immediately and for so long as such Put Option Event continues by the Purchaser. In
the event Purchaser elects to exercise its Put Option, Purchaser shall deliver written notice to the Company specifying the closing date which date shall be forty-five (45) days from the Put Option Trigger (or such earlier date as the Purchaser
and the Company may agree, the “Put Option Closing Date”), which notice must be given within sixty (60) days of the Put Option Trigger. Failure to provide notice by such times will be deemed an irrevocable waiver of the right
to exercise the Put Option. On the Put Option Closing Date, the Company shall repurchase from Purchaser the Assigned Interests at the Put/Call Price in cash, the payment of which shall be made by wire transfer of immediately available funds to the
account designated by Purchaser. Notwithstanding anything to the contrary contained herein, immediately upon the occurrence of a Bankruptcy Event, 

  
 43 

 
Purchaser shall be deemed to have automatically and simultaneously elected to have the Company repurchase from Purchaser the Assigned Interests for the Put/Call Price in cash and the Put/Call
Price shall be immediately due and payable without any further action or notice by any party.  
 (ii) If a Put Option
Event shall have occurred and be continuing, and the Company fails to pay, when and as required to be paid under this Section 5.05, the Purchaser may, with or without notice, (i) declare all or any portion of the Obligations to be
forthwith due and payable without presentment, demand, protest or further notice of any kind, all of which are expressly waived by the Company; and (ii) exercise any rights and remedies provided to the Purchaser under any Transaction Document
and/or pursuant to any applicable Laws or in equity, including all remedies provided under the UCC. 
 (b) Call Option. At any time
after the second anniversary of the Effective Date, the Company shall have the right, but not the obligation (the “Call Option”), exercisable upon ten (10) days’ written notice to Purchaser, to repurchase the Assigned
Interests from Purchaser at a repurchase price equal to the Put/Call Price. In order to exercise the Call Option, the Company shall deliver written notice to Purchaser of its election to so repurchase the Assigned Interests not less than ten
(10) days prior to the proposed closing date (the “Call Closing Date”); provided, however, that such notice may state that it is conditioned upon the effectiveness of any financing transaction or one or more other
events specified therein (including the occurrence of a Change of Control), in which case such notice may be revoked by the Company (by notice to Purchaser on or prior to the specified effective date) if such condition is not satisfied. On the Call
Closing Date, the Company shall repurchase from Purchaser the Assigned Interests at the Put/Call Price, the payment of which shall be made by wire transfer of immediately available funds to the account designated by Purchaser. Immediately upon
exercise by the Company of the Call Option and the payment by the Company to Purchaser of the Put/Call Price, Purchaser shall be deemed to have automatically assigned to the Company all right, title, and interest in and to the Assigned Interest.
 
 (c) Put/Call Payment Prior to Funding Date. It is understood and agreed that the Put/Call Price prior to the
Funding Date shall be deemed to be zero. 
 (d) Obligations of Purchaser. In connection with the consummation of a repurchase of the
Assigned Interests pursuant to the Put Option or the Call Option, Purchaser agrees that it will (i) promptly but no later than three (3) Business Days after any request therefor execute and deliver to the Company such releases, discharges,
UCC termination statements and other documents as may be necessary to release and/or discharge Purchaser’s Lien on the Collateral and otherwise give effect to such repurchase and (ii) take such other actions or provide such other
assistance as may be necessary or as reasonably requested by the Company to give effect to such repurchase. 
 Section 5.06 Intellectual
Property. 
 (a) Without limiting the Company’s obligations under Section 5.02, the Company shall, at its sole expense,
either directly or by causing Hanmi or any Licensee to do so, take such actions (including taking legal action to specifically enforce the applicable terms of any Hanmi License Agreement or License Agreement), to prepare, execute, deliver and file
any and all agreements, documents or instruments which are necessary to diligently prosecute and maintain 

  
 44 

 
the Material Patents consistent with prudent business practice. Except to the extent not permitted under the terms of the Hanmi License Agreement or any other License Agreement, the Company shall
use reasonable efforts consistent with sound business judgment to seek and to apply for patent term extensions, pediatric data package exclusivity extension, supplementary protection certificates, any functional equivalents of any of the foregoing,
or similar means of extending market exclusivity or patent protection (collectively, “Patent Term Extensions”) for any Intellectual Property or the Product in each territory where such items are permissible, as the case may be. The Company
shall not take any action to prosecute and maintain the Material Patents or fail to take any action to prosecute and maintain the Material Patents, which would reasonably be expected to result in a Material Adverse Effect. Notwithstanding the
foregoing, the Company agrees to use Commercially Reasonable Efforts to apply any Patent Term Extension based on the Regulatory Approval of the Product in the United States to U.S. Patent No. 7,625,926, unless otherwise approved in writing by
the Purchaser in Purchaser’s reasonable discretion, provided that Purchaser shall not have the right to withhold any approval if U.S. Patent No. 7,625,926 is exclusively licensed to a Licensee who is also granted the right to control
Patent Term Extensions for the Product in the U.S. 
 (b) In the event that the Company or the Purchaser becomes aware of any actual or
suspected infringement or invalidity claims by a Third Party related to any activity by such Third Party that is competitive with the Commercialization of the Product or any claim of invalidity by any Third party directed to any Intellectual
Property that is material to or necessary for the Commercialization of the Product, including the Material Patents, then promptly following the Company or the Purchaser, respectively, becoming aware of such actual or suspected infringement or
invalidity claim, the Company or the Purchaser, respectively, shall inform the other party hereto of such actual or suspected infringement or invalidity claim and shall, in addition to such notice, provide to the other party any material information
within such party’s possession pertaining thereto (which may be subject to agreement necessary to protect privilege, confidentiality and the like with respect to such information). The Company shall use Commercially Reasonable Efforts to defend
or assert the Intellectual Property, including the Material Patents against such infringement or interference by any other Persons marketing or commercializing any product that is directly competitive with the Product, and against any claims of
invalidity or unenforceability of the Intellectual Property, including the Material Patents, in the Major Countries (including, by bringing any legal action for infringement or defending any counterclaim of invalidity or action of a Third Party for
declaratory judgment of non-infringement or non-interference). The Company will keep the Purchaser reasonably informed with respect to the status of any such enforcement
and/or defense of the Intellectual Property as the Purchaser may, from time to time, reasonably request. The Company shall not, and shall use its Commercially Reasonable Efforts to cause any Licensee not to, disclaim or abandon, or fail to take any
action necessary to prevent the disclaimer or abandonment of, the Intellectual Property, including the Material Patents, except where the failure to do so would not reasonably be expected to result in a Material Adverse Effect. 

(c) In the event that the Company becomes aware that the Product infringes or violates any Third Party intellectual property, the Company
shall, in the exercise of its reasonable business discretion, use Commercially Reasonable Efforts to attempt to secure the right to use such Intellectual Property on behalf of itself and any affected Licensee, as applicable, except where the failure
to do so would not reasonably be expected to result in a Material Adverse Effect and all reasonable costs and amounts associated with obtaining any such license would be without any reduction in the Assigned Interests, if and as applicable. 

  
 45 

 (d) [reserved]. 

(e) In no event shall (i) the Company or any of its Affiliates assign, sell, transfer, license (other than pursuant to a Permitted
Licensing Agreement) or otherwise encumber any of the Intellectual Property, and for certainty, the Platform Intellectual Property (other than Permitted Liens), or (ii) the Company delegate any of the Company’s duties with respect to the In-Licensed Patents, in each case if such assignment, sale, transfer, other encumbrance or delegation would reasonably be expected to result in a Material Adverse Effect, without the prior written consent of the
Purchaser. 
 Section 5.07 Protective Covenants. The Company shall not, without the prior written consent of the
Purchaser: 
 (a) Forgive, release or compromise any amount owed to the Company or its Subsidiaries or its Affiliates and relating to the
Assigned Interests outside the ordinary course of business; 
 (b) Waive, amend, cancel or terminate (other than expiration in accordance
with its terms), exercise or fail to exercise, any of its material rights constituting or relating to the Included Product Revenues outside the ordinary course of business; 

(c) Amend, modify, restate, cancel, supplement, terminate (other than expiration in accordance with its terms), waive any material provision,
or enter into any Material Contract or any other agreement, or grant any related consent thereunder, or agree to do any of the foregoing, including, entering into any agreement with any Person under the provisions of such Material Contract, (in each
case) if such action would result in a reduction of any royalty rate, distribution split or other sales based payments, up-front payment or milestone payment to the Company thereunder in respect of the
Product; provided, that this clause (c) shall not apply to any Permitted Licensing Transaction (including any a co-distribution or co-promotion agreement for the
Product entered into in connection with any Permitted Licensing Transaction); or 
 (d) Incur or assume any Indebtedness, except for
Permitted Indebtedness. 
 Section 5.08 Notice. 

(a) The Company shall provide Purchaser with written notice as promptly as practicable (and in any event within ten (10) Business Days)
after becoming aware of any of the following: 
 (i) any material breach or default by the Company of any covenant, agreement
or other provision of this Agreement, or any other Transaction Document; 
 (ii) any representation or warranty made by the
Company in any of the Transaction Documents or in any certificate delivered to Purchaser pursuant hereto shall 

  
 46 

 
prove to be untrue, inaccurate or incomplete in any material respect on the date as of which made; 

(iii) the occurrence of a Put Option Event; 

(iv) the occurrence of any material default or event of default under any Permitted Indebtedness; 

(v) the termination of any Material Contract other than upon its scheduled termination date; 

(vi) the occurrence of any event(s) or the existence of any circumstance(s) that, individually or in the aggregate, would
reasonably be expected to result in a Material Adverse Effect; 
 (vii) the occurrence of any event or the existence of any
circumstance that (with or without notice or lapse of time, or both) would result in or serve as a basis for any, action, suit or proceeding, or any investigation or claim, or the receipt of any written notice of the foregoing, that (a) claims
that the manufacture, use, marketing, sale, offer for sale, importation or distribution of the Product as currently contemplated infringes on any Patent or other intellectual property rights of any other Person or constitutes misappropriation of any
other Person’s trade secrets or other intellectual property rights, (b) otherwise involves the Product, or (c) involves the transactions contemplated by the Transaction Documents or the Assigned Interests; or 

(viii) (i) the intention of any ERISA Affiliate to file any notice of intent to terminate any Title IV Plan, and a copy of such
notice and (ii) the filing by any ERISA Affiliate of a request for a minimum funding waiver under Section 412 of the Code with respect to any Title IV Plan or Multiemployer Plan, in each case in writing and in reasonable detail (including
a description of any action that any ERISA Affiliate proposes to take with respect thereto, together with a copy of any notice filed with the PBGC or the IRS pertaining thereto). 

(b) The Company shall provide Purchaser with written notice as promptly as practicable and in any event within ten (10) Business Days
prior to the occurrence of a Change of Control. 
 Section 5.09 Use of Proceeds. 

The Company shall use proceeds received from Purchaser in support of the Development and Commercialization of the Product and for other general
corporate purposes. 
 Section 5.10 Taxes. 

(a) Company Filings. The Company shall timely file (taking into account all extensions of due dates) all income and other material Tax Returns
required to be filed by it and will pay all Taxes required to be paid with such returns, except (i) Taxes that are being contested in good faith by appropriate proceedings and for which the Company has set aside on its books adequate reserves
with respect thereto in accordance with GAAP or (ii) to the extent that the failure to do so would not reasonably be expected to have an Material Adverse Effect. 

  
 47 

 (b) IRS Forms. Purchaser shall deliver to the Company a properly completed IRS Form W-9 or applicable IRS Form W-8, as appropriate, or any successor form, as the case may be, properly completed and duly executed by Purchaser, and such other documentation
required under the Code and reasonably requested by the Company to confirm or establish the extent to which Purchaser is or is not subject to deduction, backup withholding or withholding of U.S. federal Tax with respect to payments under this
Agreement and Purchaser will notify the Company reasonably in advance of any action or proposed action that would make any such form inaccurate and will replace the inaccurate form with an accurate one. The Company shall provide the Purchaser any
reasonable assistance it may seek in obtaining an exemption or reduced rate from, or refund of, any U.S. federal withholding tax, if applicable. Neither party shall have any obligation to gross-up or otherwise
pay the other party any amounts with respect to source withholding. 
 (c) Payments Free of Taxes. Any and all payments by or on
account of the Assigned Interests shall be made without deduction or withholding for any Taxes, except as required by any law. If any law (as determined in the good faith discretion of an applicable withholding agent) requires the deduction or
withholding of any Tax from any such payment by a withholding agent, then the applicable withholding agent shall be entitled to make such deduction or withholding and shall timely pay the full amount deducted or withheld to the relevant Governmental
Authority in accordance with applicable laws and, if such Tax is an Indemnified Tax, then the sum payable by the Company shall be increased as necessary so that after such deduction or withholding has been made the Purchaser receives an amount equal
to the sum it would have received had no such deduction or withholding been made. 
 (d) Indemnification by the Company. The Company
shall reimburse and indemnify the Purchaser, within ten (10) days after demand therefor, for the full amount of any Indemnified Taxes payable or paid by the Purchaser or required to be withheld or deducted from a payment to the Purchaser and
any reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or
liability delivered to the Company by the Purchaser shall be conclusive absent manifest error. 
 (e) Treatment of Certain Tax
Benefits. If any party to this Agreement determines, in its sole discretion exercised in good faith, that it has received a refund of any Taxes as to which it has been indemnified pursuant to this Section 5.10, it shall
pay to the indemnifying party an amount equal to such refund (but only to the extent of indemnity payments made under this Section 5.10 with respect to the Taxes giving rise to such refund), net of all out-of-pocket expenses (including Taxes) of such indemnified party and without interest (other than any interest paid by the relevant Governmental Authority with respect to
such refund). Such indemnifying party, upon the request of such indemnified party, shall repay to such indemnified party the amount paid over pursuant to this Section 5.10(e) (plus any penalties, interest or other charges
imposed by the relevant Governmental Authority) in the event that such indemnified party is required to repay such refund to such Governmental Authority. Notwithstanding anything to the contrary in this Section 5.10(e), in
no event will the indemnified party be required to pay any amount to an indemnifying party pursuant to this Section 5.10(e) the payment of which would place the indemnified party in a less

  
 48 

 
favorable net after-Tax position than the indemnified party would have been in if the Tax subject to indemnification and giving rise to such refund had not
been deducted, withheld or otherwise imposed and the indemnification payments or additional amounts with respect to such Tax had never been paid. This Section 5.10(e) shall not be construed to require any indemnified party
to make available its Tax returns (or any other information relating to its Taxes that it deems confidential) to the indemnifying party or any other Person. 

(f) Register. The Company, shall maintain at one of its offices in the United States a copy of each Assigned Interest delivered to it
and a register for the recordation of the name and address of the Purchaser and principal amounts (and stated interest) owing to the Purchaser pursuant to the terms hereof from time to time (the “Register”). The entries in the
Register shall be conclusive absent manifest error, and the Company and the Purchaser shall treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Purchaser hereunder for all purposes of this Agreement. The
Register shall be available for inspection by the Company and the Purchaser, at any reasonable time and from time to time upon reasonable prior written notice. 

Section 5.11 Compliance with Laws and Other Obligations. 

The Company will, and will cause each of its Subsidiaries to, (a) comply with all Laws (including Anti-Terrorism Laws and Sanctions)
applicable to it and its business activities in all material respects and (b) comply in all material respects with all Healthcare Laws and Governmental Licenses and Product Authorizations applicable to it and its business activities. Within 60
days after the Effective Date, the Company shall institute (if not already in effect) and thereafter maintain in effect and enforce policies and procedures reasonably designed to promote compliance by the Company, its Subsidiaries and their
respective directors, officers, employees and agents with Anti-Terrorism Laws and Sanctions. 
 Section 5.12 Maintenance of Properties, Etc.

 The Company shall, and shall cause each of its Subsidiaries to, maintain and preserve all of its assets and properties relating to the
Product or Product Commercialization and Development Activities, or that are otherwise necessary or useful in the conduct of its business in good working order and condition in accordance with the general practice of other Persons of similar
character and size, ordinary wear and tear and damage from casualty or condemnation excepted. 
 Section 5.13 Licenses. 

The Company shall, and shall cause each of its Subsidiaries to, obtain and maintain all Governmental Licenses necessary for the execution,
delivery and performance of the Transaction Documents, the consummation of the transactions thereunder or the operation and conduct of its business and ownership of its properties (including its Product Commercialization and Development Activities),
except where the failure to do so could not reasonably be expected to have a Material Adverse Effect. 

  
 49 

 Section 5.14 Maintenance of Regulatory Approvals, Contracts, Etc. 

With respect to the Product and all Product Commercialization and Development Activities, the Company will (directly or indirectly), and will
cause each of its Subsidiaries (to the extent applicable) to, (i) use Commercially Reasonable Efforts to maintain in full force and effect all Regulatory Approvals, Material Contracts and other rights, interests or assets (whether tangible or
intangible) reasonably necessary for the operations of such Person’s business, except as would not reasonably be expected to have a Material Adverse Effect, and (ii) maintain in full force and effect, and pay all costs and expenses
relating to, such Regulatory Approvals, Material Contracts owned, used or controlled by the Company or any such Subsidiary that are used in or necessary for any related Product Commercialization and Development Activities, except as would not be
reasonably expected to have a Material Adverse Effect and (iii) promptly after obtaining knowledge thereof, notify the Purchaser of any claim by any Person that the conduct of the business of the Company or any of its Subsidiaries in connection
with any Product Commercialization and Development Activities, has infringed any Intellectual Property of such Person, where such claim could reasonably be expected to have a Material Adverse Effect. 

Section 5.15 ERISA Compliance. 
 The
Company shall comply, and shall cause each of its Subsidiaries to comply, with the provisions of ERISA with respect to any Plans to which the Company or such Subsidiary is a party as an employer in all material respects. 

Section 5.16 Commercialization of the Product. 

(a) The Company itself or through one or more Subsidiaries or Licensees, shall use Commercially Reasonable Efforts to Develop and Commercialize
the Product. Without limiting the foregoing, the Company will use Commercially Reasonable Efforts to prepare, execute, deliver and file any and all agreements, documents or instruments that are necessary or desirable to secure and maintain Marketing
Authorization in the United States for the Product. The Company shall not withdraw or abandon, or fail to take any action necessary to prevent the withdrawal or abandonment of, Marketing Authorization in the United States for the Product once
obtained, other than to the extent that such withdrawal is required for safety reasons or otherwise required under applicable Law. The Company shall use Commercially Reasonable Efforts, itself or through one or more Subsidiaries or Licensees, to
Commercialize the Product in each jurisdiction in which Marketing Authorization is obtained. 
 (b) The Company shall not enter into any
Material Contract related to the Product unless the Company shall have performed reasonable and customary diligence in selecting the applicable counterparty to such Material Contract and negotiating and agreeing to the terms of such Material
Contract (or any amendment, modification, restatement, cancellation, supplement, termination or waiver of any of the material terms thereof). In addition, if any Material Contract related to the Product terminates for any reason whatsoever, the
Company shall use Commercially Reasonable Efforts to enter into a replacement Material Contract to the extent the relevant rights under such terminated Material Contract are required for the ongoing Development and Commercialization of the Product
by the Company in accordance with its express obligations set forth in Section 5.16(a). 

  
 50 

 (c) The Company shall, and shall cause its Subsidiaries to, comply with all material terms
and conditions of and fulfill all material obligations under each Material Contract (including, without limitation, each License Agreement) related to the Product to which any of them is party. Upon the occurrence of a material breach of any such
Material Contract by any other party thereto where such material breach has (or could reasonably likely to have) a material adverse effect on the Included Product Revenue, the Company shall provide written notice of such breach to Purchaser,
describing in reasonable detail the relevant breach and use Commercially Reasonable Efforts to seek to enforce all of its (or its Subsidiary’s) rights and remedies thereunder. 

Section 5.17 Payment of Obligations. 

Each of the Company and its Subsidiaries shall pay and discharge all its obligations and liabilities (a) prior to the date on which
penalties attach thereto, with respect to all material federal, state and other material Taxes imposed upon it or its properties or assets, unless the same are being contested in good faith by appropriate proceedings diligently conducted and
adequate reserves in accordance with GAAP are being maintained by the Company or its Subsidiaries and (b) as the same shall become due and payable, all lawful claims which, if unpaid, would by Law become a Lien upon any Collateral (other than
Permitted Liens). 
 ARTICLE VI 

TERMINATION 
 Section 6.01
Termination Date. 
 Except as provided in this Section 6.01 and in
Section 6.02, this Agreement shall terminate upon expiration of the Revenue Interest Period (the “Term”). Subject to the Hard Cap, if any payments are required to be made by one of the Parties hereunder
after that date, this Agreement shall remain in full force and effect until any and all such payments have been made in full, and (except as provided in Section 6.02) solely for that purpose. In addition, this Agreement
shall terminate on the Put Option Closing Date if the Purchaser shall have exercised the Put Option in accordance with Section 5.05(a) or on the Call Closing Date if the Company shall have exercised the Call Option in
accordance with Section 5.05(b), in each case upon the payment of the Put/Call Price. In addition, the Company may terminate this Agreement (x) immediately upon Purchaser’s failure to pay the Purchase Price on the
date that it is due in accordance with Section 2.03(b) unless such failure is caused by an error or omission of an administrative or operational nature and such payment is made within two days of the original due date or
(y) prior to the Funding Date, if a Change of Control has occurred. In addition, the Purchaser may terminate this Agreement if the Purchase Price Condition has not occurred by December 31, 2021. Upon expiration or termination of this
Agreement in accordance with its terms and upon payment of any amounts due to the Purchaser hereunder, all right, title, and interest in and to the Assigned Interest shall automatically revert to Company, and Purchaser will have no further rights in
the Assigned Interest or the Collateral.

Section 5.03, Section 7.05 and Section 7.19 hereof, which shall survive any termination as set forth in Section 6.01, and (b) upon the
payment and performance in full of all Obligations hereunder (other than contingent indemnification claims for which no claim has been made), the security interests in the Collateral created by any Transaction Document shall be automatically
released. Nothing contained in this Section 6.02 shall relieve any party from liability for any breach of this Agreement. In connection with any such termination and release, Purchaser shall execute and deliver to the
Company all documents the Company shall reasonably request to evidence such termination and release. 
 ARTICLE VII

 Section 7.04 Successors and Assigns. 

The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and
assigns. The Company shall not be entitled to assign any of its obligations and rights under the Transaction Documents without the prior written consent of Purchaser. Solely upon the consent of the Company (which, in the case of any proposed
assignment after the Funding Date, such consent may not be unreasonably withheld, delayed or conditioned), Purchaser may assign any of its obligations or rights under the Transaction Documents without restriction; provided that Purchaser may not
assign its rights or obligations to any Disqualified Assignee and, prior to the Funding Date, Purchaser may assign any of its rights and obligations to an Affiliate who is not a Disqualified Assignee (including an investment vehicle controlled
and/or managed by Sagard Holdings Manager LP or an Affiliate thereof) without the consent of the Company, provided, however, that (a) such Affiliate’s creditworthiness (after giving effect to such assignment) is at least as
favorable to the Company as that of Purchaser at the time of such assignment as demonstrated by the Purchaser pursuant to evidence reasonably satisfactory to the Company (it being understood and agreed that such evidence, without limitation, must
demonstrate that such Affiliate possesses committed and uncalled capital in an amount no less than the Purchase Price) or (b) Purchaser has provided, or caused Sagard Holdings Inc. (or an Affiliate thereof) to provide, the Company with an
equity commitment in an amount no less than the Purchase Price in form and substance reasonably satisfactory to the Company. 
 Section 7.05
Indemnification. 
 (a) The Company hereby indemnifies and holds Purchaser and its Affiliates and any of their respective
partners, directors, managers, members, officers, employees and agents (each, a “Purchaser Indemnified Party”) harmless from and against any and all Losses (including all Losses in connection with any product liability claims or
claims of infringement or misappropriation of any Intellectual Property rights of any Third Parties) incurred or suffered by any Purchaser Indemnified Party arising out of any breach of any representation, warranty or certification made by the
Company in any of the Transaction Documents or any breach of or default under any covenant or agreement by the Company pursuant to any Transaction Document, including any failure by the Company to satisfy any of the Excluded Liabilities and
Obligations; provided, however, that the foregoing shall exclude any indemnification to any Purchaser Indemnified Party(i) that results from the gross negligence, bad faith or willful misconduct of such Purchaser Indemnified Party, or
(ii) to the extent resulting from acts or omissions of the Company based upon and in compliance with the written instructions from any Purchaser Indemnified Party. This Section shall not apply to Taxes other than Taxes relating to a non-Tax claim or Loss governed by this Section 7.05(a). 
 (b) Purchaser hereby indemnifies and holds
the Company, its Affiliates and any of their respective partners, directors, managers, officers, employees and agents (each, a “Company Indemnified Party”) harmless from and against any and all Losses incurred or suffered by a
Company Indemnified Party arising out of any breach of any representation, warranty or certification made by Purchaser in any of the Transaction Documents or any breach of or default 

  
 54 

 
under any covenant or agreement by Purchaser pursuant to any Transaction Document; provided, however, that the foregoing shall exclude any indemnification to any Company Indemnified Party
(i) that results from the gross negligence, bad faith or willful misconduct of such Company Indemnified Party, (ii) to the extent resulting from acts or omissions of the Purchaser based upon and in compliance with the written instructions
from any Company Indemnified Party or (iii) for any matter in respect of which any Purchaser Indemnified Party would be entitled to indemnification under Section 7.05(a). 

(c) If any claim, demand, action or proceeding (including any investigation by any Governmental Authority) shall be brought or alleged against
an indemnified party in respect of which indemnity is to be sought against an indemnifying party pursuant to the preceding paragraphs, the indemnified party shall, promptly after receipt of notice of the commencement of any such claim, demand,
action or proceeding, notify the indemnifying party in writing of the commencement of such claim, demand, action or proceeding, enclosing a copy of all papers served, if any; provided, that the omission to so notify such indemnifying party
will not relieve the indemnifying party from any liability that it may have to any indemnified party under the foregoing provisions of this Section 7.05 unless, and only to the extent that, such omission results in the
forfeiture of, or has a material adverse effect on the exercise or prosecution of, substantive rights or defenses by the indemnifying party. In case any such action is brought against an indemnified party and it notifies the indemnifying party of
the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably
satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and after notice from the indemnifying party to such indemnified party of its election so to assume the
defense thereof, the indemnifying party will not be liable to such indemnified party under this Section 7.05 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense
thereof other than reasonable costs of investigation. In any such proceeding, an indemnified party shall have the right to retain its own counsel, but the reasonable fees and expenses of such counsel shall be at the expense of such indemnified party
unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel, (ii) the indemnifying party has assumed the defense of such proceeding and has failed within a reasonable time to
retain counsel reasonably satisfactory to such indemnified party or (iii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both
parties by the same counsel would be inappropriate due to actual or potential conflicts of interests between them based on the advice of such counsel. It is agreed that the indemnifying party shall not, in connection with any proceeding or related
proceedings in the same jurisdiction, be liable for the reasonable fees and expenses of more than one separate law firm (in addition to local counsel where necessary) for all such indemnified parties. The indemnifying party shall not be liable for
any settlement of any proceeding effected without its written consent. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any
indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the
subject matter of such proceeding. 

  
 55 

 (d) The indemnification afforded by this Section 7.05 shall be the
sole and exclusive remedy for any and all Losses awarded against or incurred or suffered by the Purchaser Indemnified Parties against the Company in connection with the Company’s indemnification obligations hereunder and the Company Indemnified
Parties against the Purchaser in connection with the Purchaser’s indemnification obligations hereunder, in each case other than any indemnification obligations resulting from (A) the gross negligence, the bad faith or willful misconduct of
the other Party or (B) acts or omissions based upon and in compliance with the written instructions from the other Party; provided that nothing in this Section 7.05 shall alter or affect the rights of the Purchaser to
exercise remedies under the Transaction Documents in accordance with their terms or other rights of creditors under the UCC or any other applicable Law. 

(e) Notwithstanding anything in this Agreement to the contrary, the Company shall not have any liability under this Section 7.05 on any
day on which such indemnity claim under this Section 7.05 is paid by Company, in excess of the Cap Amount for such day. “Cap Amount” means, for any day on which an indemnity claim under this Section 7.05 is paid by the
Company, the excess of (x) the Hard Cap over (y) the sum of (A) the aggregate amount of Revenue Interest Payments received by the Purchaser on or prior to such day and (B) the aggregate amount of payments made under this
Section 7.05 by Company on or prior to such day. Notwithstanding anything in this Agreement to the contrary, the Purchaser shall not have any liability under this Section 7.05 in excess of the Purchase Price, in the aggregate. 

Section 7.06 No Implied Representations and Warranties. 

Each party acknowledges and agrees that, other than the representations and warranties specifically contained in any of the Transaction
Documents, there are no representations or warranties of either party or any other Person either expressed or implied with respect to the Assigned Interests or the transactions contemplated hereby. Without limiting the foregoing, Purchaser
acknowledges and agrees that (a) Purchaser and its Affiliates, together with its and its Affiliates’ representatives, have made their own investigation of the Product (including the likelihood of and the Intellectual Property and are not
relying on any implied warranties or upon any representation or warranty whatsoever as to the future amount or potential amount of the Assigned Interests or as to the creditworthiness of Company and (b) except as expressly set forth in any
representation or warranty in a Transaction Document, Purchaser shall have no claim or right to indemnification pursuant to Section 7.05 (or otherwise) with respect to any information, documents or materials furnished to
Purchaser, any of its Affiliates, or any of its or its Affiliates’ representatives, including any information, documents or material made available to Purchaser and its Affiliates and its Affiliates’ representatives in any data room,
presentation, interview or any other form relating to the transactions contemplated hereby. 
 Section 7.07 Independent Nature of
Relationship. 
 (a) The relationship between the Company and its Subsidiaries, on the one hand, and Purchaser, on the other, is
solely that of seller and purchaser, and neither Purchaser, on the one hand, nor the Company and its Subsidiaries, on the other, has any fiduciary or other special relationship with the other or any of their respective Affiliates. Nothing contained
herein or in any other Transaction Document shall be deemed to constitute the Company and its Subsidiaries and Purchaser as a partnership, an association, a joint venture or other kind of entity or legal form for any purposes, including any Tax
purposes. The Parties agree that they shall not take any inconsistent position with respect to such treatment in a filing with any Governmental Authority 

  
 56 

 (b) No officer or employee or agent of Purchaser will be located at the premises of the
Company or any of its Affiliates, except in connection with an audit performed pursuant to Section 5.01. No officer, manager or employee of Purchaser shall engage in any commercial activity with the Company or any of its
Affiliates other than as contemplated herein and in the other Transaction Documents. 
 (c) The Company and/or any of its Affiliates shall
not at any time obligate Purchaser, or impose on Purchaser any obligation, in any manner or respect to any Person not a party hereto. 

Section 7.08 Tax Treatment. 

The Purchaser and the Company acknowledge (a) that, for U.S. federal and applicable state and local income tax purposes, they agree to
treat the rights and interests in and to the Assigned Interests that are transferred pursuant to this Agreement as indebtedness subject to the U.S. Treasury Regulations Section 1.1275-4 governing
contingent payment debt instruments, and (b) that the rights in respect of the Purchase Price constitute a debt instrument for U.S. federal and applicable state and local income tax purposes. The parties hereto agree not to take any position
that is inconsistent with the provisions of this Section 7.08 on any tax return or in any audit or other administrative or judicial proceeding unless (i) the other parties to this Agreement have consented in writing to
such actions, which consent shall not be unreasonably withheld or delayed, or (ii) the party that contemplates taking such an inconsistent position has been advised by nationally recognized counsel or accounting firm in writing that it is more
likely than not that the inconsistent position is required by applicable law. 
 Section 7.09 Entire Agreement. 

This Agreement, together with the Exhibits and Schedules hereto (which are incorporated herein by reference), and the other Transaction
Documents constitute the entire agreement between the parties with respect to the subject matter hereof and supersede all prior agreements (including the Term Sheet), understandings and negotiations, both written and oral, between the parties with
respect to the subject matter of this Agreement. No representation, inducement, promise, understanding, condition or warranty not set forth herein (or in the Exhibits, Schedules or other Transaction Documents) has been made or relied upon by either
party hereto. None of this Agreement, nor any provision hereof, is intended to confer upon any Person other than the parties hereto any rights or remedies hereunder.

hereto. No waiver of any right hereunder shall be effective unless such waiver is signed in writing by the party against whom such waiver is sought to be enforced. 

  
 57 

 (b) No failure or delay by either party in exercising any right, power or privilege
hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The rights and remedies herein provided shall be
cumulative and not exclusive of any rights or remedies provided by law.

Non-Disturbance; Intercreditor.

Working Capital Facility pursuant to which the Liens granted to the Purchaser pursuant to the Transaction Documents on Working Capital Collateral (other than the Assigned Interest) shall be subordinated to the Liens on such collateral securing the

Purchaser shall, at the reasonable request of the Company, enter into non-disturbance and similar agreements in connection with the licensing of any Intellectual Property and other general intangibles covering

transactions permitted pursuant to this Agreement, Purchaser agrees, at the request of the Company, to execute and deliver such documents as the Company may reasonably request to evidence such non-disturbance
or similar agreement which shall be on terms reasonably satisfactory to the Purchaser, provided that the security interests of the Purchaser in the Intellectual Property shall not be affected.

The Purchaser agrees to keep confidential all non-public information provided to it by the Company
