and records with respect thereto maintained, in accordance with normally accepted accounting principles, such as GAAP, IFRS or similar accounting principles, on a basis consistent with the audited consolidated financial statements of Almirall, Aqua,
their Affiliates, or Sublicensee, as applicable.

Proprietary Information (other than Almirall Trademarks and Almirall Product-Related Material) for the Development or Commercialization of a Line Extension Product or any indication of the Licensed Products other than the Initial Indication
(“Athenex Sublicensing Agreement”), Athenex (i) shall assure that any such Athenex Sublicensing Agreement contains a clause permitting Almirall rights hereunder to all Know How generated by such sublicensees with respect
to Licensed Products and (ii) Athenex shall, pursuant to subsection (c3), permit Almirall to participate in the commercial benefit Athenex will obtain from such Third Party sublicensee for the use and commercial exploitation of such Almirall

Extension Product or any additional indication (other than the Initial Indication) of the Licensed Products. 
 (c3) The Parties shall use

Intellectual Property and Almirall’s Proprietary Information (other than Almirall Trademarks and Almirall Product-Related Material) in the Development or Commercialization of a Line Extension Product or additional indications of Licensed
Products (other than the Initial Indication), based on the value and importance of such Almirall Intellectual Property and/or Proprietary Information in the Commercialization of such Line Extension Product or additional indications, before
(i) Athenex enters into each Athenex Sublicensing Agreement or (ii) Athenex itself exploits Almirall Intellectual Property or Almirall’s Proprietary Information to Develop or Commercialize a Line Extension Product or any additional
indications (other than the Initial Indication) of Licensed Products. If the Parties are unable to reach such an agreement within ninety (90) days of the initiation of such negotiations, the Parties agree to engage an independent certified
public accounting firm of recognized standing (i.e. one of the so-named Big Four accounting firms provided that it is not the then auditing firm of any of the Parties), for resolution based on the factors set

such an agreement nor determination shall be required in advance of any execution or effectiveness of any Athenex Sublicensing Agreement, practice of any rights thereunder, or direct exploitation of any such Almirall Intellectual Property and/or
Proprietary Information by Athenex or any

Affiliate thereof and (ii) Athenex’s, its Affiliates’, or any of its or their licensees’ or sublicensees’ use of any intellectual property developed by or on behalf of
Athenex or any Affiliate thereof, including that developed in the course of seeking or obtaining the Regulatory Approval in the U.S. of any Line Extension Product or indication other than the Initial Indication (or performing any Development under
this Agreement), will not be subject to any payment to Almirall.

(a) All rights not specifically granted to Almirall under this Agreement are reserved and retained by Athenex. Nothing in this Agreement shall
be deemed to constitute the grant of any license or other right to Almirall, to or in respect of any product, patent, trademark, Proprietary Information, trade secret or other data or any other intellectual property of Athenex or any Affiliate
thereof, except as set forth under this Agreement.

 3.3 Development. 

(a) General. Subject to this Section 3.3 and the applicable terms of this Agreement, (i) Athenex shall Develop Licensed
Products in the Field in the Territory in accordance with the Development Plan, as it may be revised from time to time in accordance with Section 3.3(b)(i), and (ii) Almirall shall use Commercially Reasonable Efforts to obtain Regulatory
Approval of the Current Product in at least one of the Major European Markets. Without prejudice to the studies and activities included in the Development Plan, Athenex shall conduct all development studies to the extent required or necessary for
Regulatory Approval for the Current Product in the U.S. 
 (b) Development Plan. 

(i) Development Plan. Attached as Schedule 3.3(b)(i) is the Development Plan (the “Development
Plan”), which contains a detailed list of Athenex Studies, provisions governing all regulatory work expected as of the Execution Date, all Development and regulatory milestones, the corresponding timelines to conduct all such activities and
the corresponding allocation of responsibilities between the Parties to conduct all such activities. The Development Plan shall be amended to include any additional study necessary for the purposes of obtaining Regulatory Approval for the Current
Product in the Field in the U.S. For this purpose, each Party shall provide the other Party and the Joint Steering Committee as soon as possible following it becoming reasonably apparent to such Party that additional studies will be required for
such Regulatory Approval, any proposed amendments to the Development Plan and protocols for additional Athenex Studies proposed to be included therein. Each Party and the Joint Steering Committee shall give good faith consideration to all
substantive comments timely provided by a Party with respect thereto and the Joint Steering Committee will adapt the Development Plan as needed to include any such additional requirement for Regulatory Approval for the Current Product in the Field
in the U.S. Once approved in accordance with this Agreement, a revised Development Plan shall replace the prior Development Plan. The Development Plan shall in no event be amended in a manner that would require either Party to perform any assignment
or task in a manner that would violate any applicable Law. In the event of a change in any applicable Law, the Parties shall work together in good faith to amend the Development Plan to enable each Party to comply fully with such Law. If such
amendment is not approved, the affected Party would be excused from performing any activity specified in the Development Plan that would violate or result in a violation of any applicable Law. For certainty, changes of the Development Plan shall be
treated as changes of this License Agreement and will be subject to a written separate document signed by authorized representatives of each Party and appended hereto. 

(ii) Performance of Development Plan. Athenex shall perform its obligations under the Development Plan according
to the time-lines set out in the Development Plan, in a professional manner, and otherwise in compliance in all material respects with the Development Plan and the requirements of applicable Laws and all applicable GCP, GLP, and cGMP. Almirall
shall, as reasonably requested by Athenex, provide reasonable assistance and expertise with respect to the Development Plan or performance thereof.

 EXECUTION DRAFT 
  

 (iii) Step-in right. Athenex
shall promptly inform the Joint Steering Committee if Athenex identifies any actual or possible deviation in the timelines included in the Development Plan attributable to Athenex, in a way that will delay the expected deadline for the NDA
submission identified in the Development Plan (a “Delay”). Once informed, the Joint Steering Committee shall meet and analyze the reason for the Delay and shall decide the best reasonable course of action to eliminate or mitigate
such a Delay. Should the Joint Steering Committee be unable to reach an agreement upon the best reasonable course of action within fifteen (15) days and, therefore, Athenex do not start conducting the activities needed to mitigate or eliminate
the Delay, then Almirall will be entitled to perform such needed activities at Almirall’s costs, provided that Almirall shall be entitled to offset such costs with the next following payment to be made by Almirall to Athenex in accordance with
the Agreement. However, should the Joint Steering Committee confirm in good faith that the Delay cannot be remedied, with or without Almirall step-in right and, therefore, that the commercial value of the
Licensed Product as of the Execution Date has decreased, then Almirall shall have the right to, and the Parties shall, adjust the financials of the Agreement in a way that will reflect such decrease of the commercial value of the Licensed Products
as of the Execution Date. The Parties shall meet at that moment to identify the best mechanism to reflect such decrease in the financials of the Agreement. 

(iv) Additional Studies for Regulatory Approval of Current Product in Europe. If, at any time, it is reasonably
determined by Almirall that additional Clinical Studies will be needed to obtain Regulatory Approval of the Current Product in at least three (3) of the Major European Markets, Almirall shall use best efforts to discuss with the relevant
Regulatory Authority(ies) in the Major European Markets and minimize the number and size of, and time required to complete, such Clinical Studies, if not eliminate such need altogether. If, despite such efforts, additional Clinical Studies are still
required to obtain Regulatory Approval of the Current Product in at least three (3) of the Major European Markets, the matter shall be referred to the Joint Steering Committee (or, if it cannot reach consensus in a reasonable period of time,
the Chief Executive Officers of Almirall and Athenex) who shall promptly meet and use reasonable efforts in good faith to agree on how to allocate the conduct and financial support of such Clinical Studies between the Parties. Unless otherwise
agreed unanimously by the Joint Steering Committee or, in the event such matter is referred to the Chief Executive Officers, in writing in the Chief Executive Officers’ discussions, each Party shall be responsible for fifty percent (50%) of the
cost of such Clinical Studies. 
 (c) Responsibilities of the Parties. 

(i) Athenex. Athenex shall have primary responsibility for Development required for Regulatory Approval of Current
Product in the Field in the U.S. and primary responsibility for the following activities connected with the Line Extension Product. Such responsibilities shall include: (i) conducting and completing the Development Studies; (ii) conducting
and completing CMC Development for the Line Extension Product and (iii) conducting and completing a Phase II Clinical Study for the Line Extension Product, provided that Almirall has approved through the Joint Steering Committee the performance

respond substantively to any communication with a particular Regulatory Authority or otherwise make any submissions to a Regulatory Authority concerning, in either case, the Licensed Product in the Field, without first giving the other Party a
reasonable opportunity to review and comment, such opportunity not to be required to exceed ten (10) Business Days, unless the urgency of such matter and its related response reasonably precludes providing the other Party such an opportunity,
in which case the responsible Party shall be entitled to respond as it determines in its reasonable discretion. The Party responsible for filing an application for Regulatory Approval in a particular country of the Territory shall review and
consider in good faith any reasonable comments received from the other Party related to communications or submissions to and from the relevant Regulatory Authority(ies) in such country related to any Licensed Product and any reasonable comments or
suggestions from the other Party otherwise related to any of the Regulatory Approvals for any Licensed Product in such country. In the event the other Party raises any reasonable, objection to any such submission to a Regulatory Authority, including
the proposed Product Label or any formulation changes, such matters shall be subject to resolution by the Joint Steering Committee. If the Joint Steering Committee becomes deadlocked with respect to such matters, such matters shall be as determined
by Athenex when affecting only to the U.S and by Almirall when affecting only to Europe, in its reasonable discretion, except that, in such cases, Athenex may not, without Almirall’s consent (such consent not to be unreasonably withheld,
conditioned or delayed), so determine any matter in a manner that (i) is reasonably likely to adversely affect the Commercialization of a Licensed Product in the Field in the Territory, including changes to Product Labeling that are reasonably

to the Licensed Products that are going to be registered and commercialized outside the Territory. 
 (h) Limitation of powers. For
greater certainty, the Joint Steering Committee cannot make any decision that will materially alter the terms of this Agreement or materially affect the rights and obligations of the Parties under this Agreement without first obtaining the written
consent of the Parties, which written consent will then be appended to and become part of this Agreement. 
 (i) Alliance Managers.

achievement of any of the milestone events. As a matter of clarification, the payments referred to in this Section 4.4 shall be made one time upon the initial satisfaction of the applicable Milestone Event. 

4.5 Royalties. 
 (a) Almirall and Aqua
shall pay Athenex as a Calendar Quarter royalty during the Royalty Term a percentage of Net Sales of Licensed Products in the Territory, based upon the following tiered royalty rates (“Royalties”):

	 Less than or equal to $[*]
	  	 	15	% 
	 Greater than $[*] and less than or equal to $[*]
	  	 	[*]	% 
	 Greater than $[*] and less than or equal to $[*]
	  	 	[*]	%

	  	 	[*]	% 
	 Greater than $[*] and less than or equal to $[*]
	  	 	[*]	% 
	 Greater than $[*]
	  	 	[*]	% 

 For example, if the total Net Sales of all Licensed Products sold in the Territory for a given Calendar Year is
$[*], and no such Net Sales were by Sublicensees in Small Countries, then Almirall shall, without taking into account any adjustments set forth below O, pay Athenex a royalty of $[*] for such Calendar Year (([*]% x $[*]) + ([*]% x $[*]) + ([*]% x
$[*]) + ([*]% of $[*])). Each of Almirall’s and Aqua’s percentage contribution to any Royalty payment under this Section 4.5(a) will reflect the proportion of its sales that comprise the Net Sales. 

(b) The Net Sales in a country in the Territory of each Licensed Product considered for the purposes of calculating the Royalty (but not
for purposes of calculating Net Sales for purposes of determining the applicable royalty rate under the table above) shall be reduced (i) by [*] percent ([*]%) on the first date in such country on which there are no Valid Claims of any Athenex
Patent Rights covering such Licensed Product (or the use or manufacture thereof), (ii) by an additional [*] percent ([*]%) when a first Generic Entry occurs with respect to such Licensed Product in such country; (iii) by an additional [*]
percent ([*]%) when a second Generic Entry occurs with respect to such Licensed Product in such country; and (iv) to no Royalty when a third Generic Entry occurs with respect to such Licensed Product in such country.

 4.6 Royalty Reports and Payments. 

(a) Royalty Payments. Almirall shall pay the Royalty on a Calendar Quarter basis during the applicable Royalty Term(s) in accordance
with the Net Sales achieved during the corresponding Calendar Quarter. Not later than 15th February, 15th May, 15th August and 15th November of each Calendar Year Almirall shall provide Athenex with an accounting report for such applicable Calendar
Quarter for each relevant country within the Territory, which sets forth the gross sales, Net Sales and the Royalties payable by Almirall and Aqua to Athenex for such Calendar Quarter, with a breakdown of all deductions taken in any such
calculations, in accordance with the definition of “Net Sales”. Any conversion to Dollars shall be calculated in accordance with Section 4.7(d). Royalties shown to have accrued by each report shall be due and payable in accordance
with Section 4.7(a) below. Almirall shall pay each Royalty amount not later than sixty (60) days following the end of the corresponding Calendar Quarter. Within the first forty five (45) days of each Calendar Year, Almirall shall
inform Athenex about the total Net Sales achieved during the preceding Calendar Year and should such real Net Sales demonstrate that a different Royalty rate should have applied in accordance with the chart above, then the corresponding overpayment
or underpayment shall be paid to the Party in bonis. 
 (b) Records. Almirall and Aqua shall keep, and require its Affiliates
and its and their Sublicensees to keep, complete and accurate records in sufficient detail to permit accurate determination of all amounts necessary for calculation and verification of all payment obligations set forth in this Article 4 for a
period of thirty-six (36) months from the end of the relevant Calendar Year. 
 4.7 General Payment
Provisions. 
 (a) Payment Method. All payments under this Agreement shall be made in Dollars by bank wire transfer in immediately
available funds to an account opened at Athenex’s name in a bank located in the U.S. All payments other than royalties payable under Section 4.5 (which shall be payable as provided in Section 4.6(a)) will be provided within thirty
(30) calendar days after receipt of an Athenex’s valid invoice issued for the corresponding payment. 
 (b) Withholding
Taxes. A Party (“Payor”) required to pay the other Party (the “Payee”) under this Agreement may deduct from the corresponding amount due hereunder the amount of any taxes imposed on the Payee which are required to be
withheld or collected by the Payor, its Affiliates, or its or their Sublicensees under the laws, rules or regulations of any country on amounts owing from Payor to Payee hereunder. Any such taxes required to be withheld or collected shall be paid or
withhold, as required by Law, by Payor but an expense of Payee. To the extent Payor, its Affiliates, or its or their Sublicensees pay such withholding taxes to the appropriate governmental authority on behalf of Payee; Payor shall promptly deliver
to Payee proof of payment of such taxes. Payor cooperate with Payee, as reasonably requested thereby and at Payee’s expense, in claiming any exemption from any such withholdings under any double taxation or similar agreement or treaty from time
to time in force or in otherwise seeking the return, refund, or credit of any such withheld amount. If Payor had a duty to withhold taxes in connection with any payment it made to Payee under this Agreement but Payor failed to withhold, and such
taxes were assessed against and paid by Payor, then Payee will indemnify and hold harmless Payor from and against such taxes (including interest). If Payee makes a claim under this Section 4.7(b), it will comply with the obligations imposed
above as if Payor had withheld taxes from a payment to Payee.

 (c) Tax Residence Certificate. A Party entitled to receive a payment pursuant to this
Agreement shall provide the remitting Party appropriate certification from the relevant revenue authorities that such receiving Party is a tax resident of that jurisdiction (a “Tax Residence Certificate”), if such receiving Party wishes to
claim the benefits of an income tax treaty to which that jurisdiction is a party. Upon the receipt thereof, any deduction and withholding of taxes by the remitting Party shall be made at the appropriate treaty tax rate. 

(d) Currency Exchange. With respect to Net Sales invoiced or expenses incurred in a currency other than Dollars, such Net Sales invoiced
or expenses incurred will be converted into the United States dollar equivalent using a rate of exchange that corresponds to the rate used to record such receipt or expenditure for IFRS reporting purposes for the respective reporting period. If a
Party is not required to perform such currency conversion for its IFRS reporting, then for such period such Party will convert its amounts received and expenses incurred into Dollars using a rate of exchange that corresponds to the noon buying rate
as published by the Wall Street Journal, Eastern U.S. Edition on the last Business Day of the applicable reporting period (or such other publication as agreed-upon by the parties). 

(e) Financial Accounting Standards. Except as otherwise defined herein, all financial calculations by either Party under this Agreement
shall be calculated in accordance with IFRS. 
 4.8 Audits. 

(a) Upon the written request of Athenex, Almirall and Aqua shall permit, and shall ensure that their Affiliates and its and their licensees and

selected by Athenex , to have access not more than once in any Calendar Year, during normal business hours, to such of the records of Almirall or Aqua, their Affiliates, and their Sublicensees as may be reasonably necessary to verify the accuracy of
any notices or reports due under this Article 4, or any payments due under this Article 4, for any Calendar Year ending not more than thirty-six (36) months prior to the date of such request (each
Calendar Year will be audited only once in total). The accounting firm shall disclose to Athenex whether the reports are correct or incorrect, the specific details concerning any discrepancies (including the accuracy of the calculation of Net Sales
and the resulting effect of such calculations on the amounts payable by Almirall or by Aqua under this Agreement) and such other information that should properly be contained in a report required under this Agreement (the “Audit
Report”). 
 (b) If such accounting firm concludes that additional amounts were owed with respect to any Calendar Year subject to an
audit hereunder, then Almirall and/or Aqua (as the case may be) shall pay any additional payments owing in respect of its/their respective obligation(s) under this Article 4, together with interest at the Prime Rate on the amount of such additional
payments, within thirty (30) days of the date Athenex delivers the Audit Report to Almirall and Aqua. In the event such accounting firm concludes that amounts were overpaid by Almirall and/or Aqua during such period, Athenex shall repay
Almirall and/or Aqua the amount of such

overpayment within thirty (30) days of the date Athenex delivers to Almirall and Aqua such accounting firm’s Audit Report. The fees charged by such accounting firm shall be paid by

 (z) The Athenex Know How has been kept confidential or has been disclosed to Third Parties
only under terms of confidentiality; and 
 (aa) As of the Execution Date, no other compounds with similar src and pretublin
inhibition are being developed by or on behalf of Athenex or any Affiliate thereof for dermatology indications in both clinical and preclinical studies.

or commercial collaboration with respect to such New Product (a “New Product Transaction”) to Almirall in writing before offering any such transaction to any Third Party and, if, within thirty (30) days of Athenex’s
provision of such notice (such thirty (30) day period, the “ROFN Notice Period”), Almirall notifies Athenex in writing of Almirall’s desire to negotiate an agreement for a New Product Transaction (such notice, a
“Negotiation Notice”), the Parties shall use reasonable efforts to negotiate, on an exclusive basis, in good faith the terms and conditions applicable to a New Product Transaction during a period of one hundred twenty
(120) days following such notice from Almirall. Should (i) the Parties not agree on such terms and conditions within the one hundred twenty (120) day negotiation period, (ii) Almirall inform Athenex that it is not interested in
executing a New Product Transaction under the terms and conditions offered by Athenex, or (iii) Almirall not provide a Negotiation Notice during the thirty (30) day ROFN Notice Period, then Athenex will be entitled to (X) discuss,
propose, negotiate, and/or execute a New Product Transaction for the applicable New Product(s) with a Third Party, provided that (1) if Almirall provided a Negotiation Notice with respect to such New Product(s), the terms of any such agreement
executed with a Third Party shall not be for rights to the applicable New Product(s) other than rights substantially equivalent to those proposed in, and shall not be on material terms more favorable on the whole to such Third Party than, the last
terms offered to Almirall by Athenex unless Athenex has provided first to Almirall a reasonable opportunity (not to exceed ten (10) Business Days) to execute such an agreement with Athenex and (2) if a New Product Transaction with such a
Third Party is not executed within twelve (12) months following the (a) end of the one hundred twenty (120) day negotiation period, (b) date on which Almirall informs Athenex it is not interest in executing a New Product
Transaction, or (c) expiration of the ROFN Notice Period without Almirall’s exercise of its negotiation rights, as applicable, Athenex shall be required to follow the process set forth in this paragraph again with respect to such New
Product(s) before executing a New Product Transaction therefor with a Third Party, and/or (Y) further pursue development and commercialization itself (or via its Affiliates), with respect to the applicable New Product(s), and Almirall shall
have no further rights hereunder with respect to the applicable New Product(s). Notwithstanding anything to the contrary, all rights and obligations with respect to this paragraph only apply with respect to the Territory; Almirall shal have no
rights, and Athenex shall have no obligations, under this paragraph with respect to any jurisdictions outside the Territory. For purposes of this paragraph:

 (c) The responsible Party under this Section 6.2 with respect to any Patent Rights in
the Territory concerning any Licensed Product (or the manufacture or use thereof) shall use Commercially Reasonable Efforts to solicit the other Party’s review of the nature and text of any patent applications within the Territory and important
prosecution matters related thereto in reasonably sufficient time prior to the filing thereof, and the responsible Party shall use Commercially Reasonable Efforts to take into account the other Party’s reasonable comments related thereto. In
the event any of the Parties decides not to prosecute or maintain any Patent Right, such Party shall inform the other Party sufficiently in advance to permit such other Party to prosecute or maintain at its own name and expenses the corresponding
Patent Right. The Party that has decided not to prosecute or maintain a Patent Right shall take all necessary steps to transfer the corresponding Patent Right to the other Party. . 

(d) Orange Book Listings. With respect to Regulatory Exclusivity or other data exclusivity periods (such as those periods listed
in the FDA’s Orange Book (including without limitation any available pediatric extensions) and all foreign equivalents in the Territory), the Party (or Affiliate thereof) that, as between the Parties, owns or holds a Drug Approval Application
or Regulatory Approval in the Territory (the “Holder”) shall use Commercially Reasonable Efforts consistent with its obligations under Law to seek, maintain and enforce all of the foregoing available for the Licensed Products in all
countries in the Territory where Regulatory Approval is obtained. With respect to filings in the FDA Orange Book (and foreign equivalents) for issued patents for a Licensed Product, the Holder shall, consistent with its obligations under Law, list
in a timely manner and maintain any listing for all applicable Athenex Patent Rights and Almirall Patent Rights required to be filed by it, or that it is permitted to file, under Law. To the extent reasonably practicable, at least thirty
(30) days prior to an anticipated deadline for the filing of patent listing information for any Athenex Patent Rights, Almirall will consult with Athenex regarding the content of such filing. In the event of a dispute between the Parties as to
whether a Athenex Patent Right can be filed and/or the content of such filing, the Parties will take expedited steps to resolve the dispute as promptly as possible, including seeking advice of an independent legal counsel to guide their decision.
Athenex shall reasonably cooperate with Almirall, at Almirall’s expense, in filing and maintaining such Orange Book (and foreign equivalent) listings.

 EXECUTION DRAFT 
  

 (b) Athenex shall have the first right to initiate and prosecute such legal action in the
Territory at its own expense and in the name of Athenex, or to control the defense of any declaratory judgment action in the Territory relating to the Athenex Intellectual Property, and Athenex shall provide Almirall with reasonable notice of any
such action it commences and consult with Almirall on any significant developments in such action. Almirall shall render, at its expense, all assistance reasonably requested in connection with any action taken by Athenex or to prevent such
infringement (including reasonable attorneys’ fees). However, the control of such action, including whether to initiate any legal proceeding and/or the settlement thereof, shall be under the control of Athenex; provided that
Athenex shall consult with Almirall on all relevant aspects of the action and in particular shall not settle any such claim or proceeding in a manner that would adversely affect Almirall, any Affiliate thereof, or their rights under this Agreement
without Almirall’s prior written consent, which consent shall not be unreasonably withheld, conditioned or delayed. 
 (c) If Athenex
elects not to initiate and prosecute an infringement or defend a declaratory judgment action in any country in the Territory as provided in Section 6.3(b) within sixty (60) days after having become aware of such potential infringement or
any shorter period needed under applicable Law to permit Almirall to elect, which election shall be subject to and consulted with Athenex, to take such action that is reasonably necessary and appropriate to terminate or prevent such infringement
solely to the extent corresponding to the exclusive rights in the Field granted to Almirall under this Agreement, including instituting an infringement proceeding, provided, however, that Almirall shall not enter into any settlement or
compromise of any such claim without Athenex’s prior written consent, which consent shall not be unreasonably withheld, conditioned or delayed. 

(d) Hatch-Waxman Act Litigation. Notwithstanding anything herein to the contrary, should a Party or any Affiliate thereof receive
a certification for a Licensed Product in the Field pursuant to the Drug Price Competition and Patent Term Restoration Act of 1984 (Public Law 98-417), as amended (the “Hatch-Waxman
Act”), including any notice under 21 U.S.C. §355(b)(2)(A)(iv) or 355(j)(2)(A)(vii)(IV) or a similar notice with respect to, in either case, any Licensed Product, or its equivalent in a country in the Territory other than the
U.S., then such Party shall immediately (and in any event no later than within two (2) Business Days after such receipt) provide the other Party with a copy of such certification. Both Parties will then agree the best course of action with the
objectives of defending the patents and ensuring the cessation of any infringing act, including bringing any necessary suit within the deadlines contemplated in the Hatch-Waxman Act. The corresponding costs will be shared at 50%. Notwithstanding the
foregoing, (i) no Party shall take any action in the course of exercising its rights under this Section 6.3(d) that (x) admits fault or wrongdoing, or incurs liability, on the part of the other Party, (y) materially limits the
scope, validity, or enforceability of any of the Athenex Patent Rights in respect to any Licensed Product in the Field in the Territory (if Athenex or any Affiliate thereof is bringing the suit) or materially limits the scope, validity, or
enforceability of any of the Athenex Patent Rights in respect to any Licensed Product outside the Field (or any corresponding Patents owned or controlled by Athenex outside the Territory) or any product other than Licensed Product in the Field (if
Almirall or any Affiliate thereof is bringing the suit), or (z) would reasonably be expected to materially adversely affect the ability of the Party not bringing the suit to develop or commercialize any Licensed Product in the Field in the
Territory (if Athenex is bringing the suit) or to develop or commercialize any Licensed Product outside the Territory or outside the Field or any other products (other than Licensed Products) covered by the Athenex Patent Rights (or any
corresponding Patents owned or controlled by Athenex outside the Territory) (if Almirall or any Affiliate thereof is bringing the 

  
 52

suit), without the prior written consent of the Party not bringing the suit, which such Party may withhold in its sole discretion acting in good faith. The Parties shall in any case consult with
each other at all times during the litigation and they shall not enter into any settlement agreement with any Third Party without the other Party’s prior written consent, which consent shall not be unreasonably withheld, conditioned or delayed.

 (e) Athenex shall have the sole right to initiate and prosecute any legal action outside the Territory, outside the Field, or with respect
to any product other than Licensed Products under the Athenex Intellectual Property Rights (or any corresponding Intellectual Property Rights owned or controlled by Athenex outside the Territory), at its own expense and in the name of Athenex, or to
control the defense of any declaratory judgment action outside the Territory relating to such Intellectual Property Rights. However, the control of such action, including whether to initiate any legal proceeding and/or the settlement thereof, shall
solely be under the control of Athenex, with the proviso that Athenex shall keep Almirall informed of any relevant development in the actions and that any such Athenex actions and decision shall not negatively impact Almirall Development and
Commercialization of the Licensed Products in accordance with the Agreement. 
 (f) For any legal action or defense in the Territory with
respect to the Athenex Intellectual Property Rights contemplated by this Section 6.3, in the event that any Party is legally unable to initiate, prosecute, or defend such action solely in its own name, the other Party will join such action
voluntarily and will execute all documents necessary for the Party to prosecute, defend and maintain such action. In connection with any such action, the Parties will cooperate fully and will provide each other with any information or assistance
that either reasonably may request, and the Party initiating, prosecuting, defending, or controlling any legal action or defense in the Territory with respect to the Athenex Intellectual Property Rights contemplated by this Section 6.3 shall
reimburse the other Party for the reasonable documented costs and expenses incurred thereby in providing such information or assistance (regardless of whether any recovery or damages are received). Any recovery or award obtained by either Party as a
result of any such action or settlement shall be shared as follows: 
 (i) the Party that did not initiate or prosecute, or
did not maintain the defense of, the action shall (without limitation of the reimbursement obligation above) recoup all of its costs and expenses (including reasonable attorneys’ fees) incurred in connection with the action, whether the
recovery or award is by settlement or otherwise; 
 (ii) the other Party then shall, to the extent possible, recover its
reasonably documented costs and expenses (including reasonable outside attorneys’ fees) incurred in connection with the action, whether the recovery or award is by settlement or otherwise; and 

(iii) the remaining recovery will be deemed to go toward Almirall’s Net Sales for that Calendar Year, and each Party shall
then be entitled to a division of the remaining portion of the recovery or award in a manner consistent with the Royalty scheme set out in Section 4.5 of this Agreement, to the extent solely and directly attributable to the infringement of the
exclusive rights to the Athenex Intellectual Property Rights granted to Almirall under this Agreement.

 6.4 Infringement of Third Party Intellectual Property. 

(a) In the event that a Party becomes aware of any claim that the Development, manufacture, import, use or Commercialization of any Licensed
Product in the Field in the Territory hereunder infringes or violates the Intellectual Property rights of any Third Party in the Territory, such Party shall promptly notify the other Party in writing. The Parties shall thereafter discuss the
situation, and to the extent reasonably necessary, use reasonable good faith efforts attempt to agree in writing on a course of action. 

(b) If, within thirty (30) calendar days of the notice set forth above, the Parties fail to agree in writing upon an appropriate course of
action with respect to such infringement or violation in the Territory, then, with respect to any claim or allegation that the practice of any Athenex Know-How or technology covered by the Athenex Intellectual
Property Rights pursuant to, in each case, this Agreement in the Field in the Territory is alleged to or does infringe the intellectual property rights of any Third Party (an “IP Claim”), Athenex shall have the obligation, to seek a
license, defend or settle any action in the Territory, or to initiate and prosecute legal action in the Territory to resolve such IP Claim. Athenex shall keep Almirall reasonably informed as to the progress of any IP Claim. Almirall shall render,
all assistance reasonably requested in connection with any action, defense, or settlement or license negotiations thereof undertaken by Athenex. However, the control of such IP Claim, including whether to initiate any legal proceeding and/or the
settlement thereof, or enter into a license with respect to the subject matter thereof, shall solely be under the control of Athenex; provided that Athenex shall not take any decision, or settle any such claim or proceeding, or enter
into any license agreement, in a manner that materially adversely affects Almirall’s rights under this Agreement or which results in any material monetary payment by or financial loss to Almirall, without Almirall’s written consent, which
consent shall not be unreasonably withheld, conditioned or delayed. Athenex shall pay for all costs and expenses incurred by Athenex in such defense, action, settlement or pursuant to such license, and, subject to subsection (f) below, Athenex
shall pay all damages awarded or settlement payments made (including future royalty or similar payments) to such Third Party with respect thereto. 

(c) If the Parties agree that it is preferable for Almirall to, or in the event an IP Claim has been initiated against Almirall, Almirall
decides to, undertake the defense, action, settlement, or seeking of a license with respect to an IP Claim or Third Party Intellectual Property rights, the reasonable, documented costs of any legal action commenced, any infringement action defended,
or settlement or license entered into with respect to any IP Claim shall be borne solely by Athenex, provided, however, that Almirall shall not enter into any settlement or compromise of, or license with respect to, any IP Claim which
results in any financial loss to or payment by Athenex, or may adversely affect (1) any Athenex Intellectual Property, (2) any corresponding Patents or other Intellectual Property rights outside the Territory, or (3) either
Party’s ability to Develop, manufacture, or Commercialize Licensed Products, or Compound, or, in the case of Athenex, other products incorporating the Compound, without the prior written consent of Athenex, which consent shall not be
unreasonably withheld, conditioned or delayed, and Athenex shall, subject to subsection (f) below, pay all damages awarded or settlement or license payments reasonably made (including future royalty or similar payments) to such Third Party with
respect to the resolution of the IP Claim. 

  
 54 









 EXECUTION DRAFT 
  

 (d) With respect to any IP Claim, in the event that any Party is legally unable to initiate,
prosecute, or defend such action solely in its own name, the other Party will join such action voluntarily and will execute all documents necessary for the Party to prosecute, defend and maintain such action. In connection with any IP Claim, the
Parties will cooperate fully and will provide each other with any information or assistance that either reasonably may request and all costs incurred in relation to such action shall, subject to subsection (f) below, be borne solely by Athenex.

 (e) Almirall shall have the sole right, but not the obligation, to defend any action against it, any Affiliate thereof, or any Sublicensee
of either of the foregoing with respect to any claim of infringement or violation of any Third Party’s intellectual property rights, other than an IP Claim by Almirall’s, its Affiliates’, or its or their Sublicensees’
Development, manufacture, or Commercialization of Licensed Products in the Field in the Territory. 
 (f) Notwithstanding anything to the
contrary, (i) Athenex shall not be obligated under this Section 6.4 to bear any amounts for damages, or payment obligations with respect to any IP Claims (other than running royalties on sales of Licensed Products in the Territory), due to
Third Parties pursuant to an IP Claim or disposition, settlement or execution of a license with respect thereto, exceeding in the aggregate (taking into account all IP Claims) the sum of all amounts previously paid to Athenex under Article 4, other
than running royalties on Net Sales under Section 4.5 (as they may be adjusted) and (ii) Athenex shall not be obligated under this Section 6.4 to bear any amount of running royalties on sales of Licensed Products in the Territory in
any particular Calendar Quarter due to Third Parties pursuant to an IP Claim or disposition, settlement or execution of a license with respect thereto exceeding the running royalties on Net Sales during such Calendar Quarter due under
Section 4.5 (as they may be adjusted). Almirall shall be responsible for any amounts for damages, or payment obligations (including running royalties), with respect to any IP Claim that exceed the foregoing limitations and shall reimburse
Athenex for any amounts incurred in excess of such limitations within thirty (30) days of Almirall’s receipt of an invoice therefor. The Parties acknowledge and agree that the intent of this subsection (f) is to ensure that the
maximum amounts for damages or other payments that Athenex would have to bear under this Section 6.4 are equal to the total amounts paid to Athenex under Article 4, and shall interpret the preceding portions hereof accordingly. 

(g) Notwithstanding anything to the contrary, (i) Athenex shall not have obligations to Almirall or otherwise with respect to any claims
of infringement or violation of Third Party intellectual property rights under this Section 6.4 with respect to (1) any API, other than a Compound proposed or made by Almirall, that is incorporated into any Licensed Product (or the use or
manufacture of such API) or (2) any changes to any Licensed Product (or its use or manufacture) proposed or made by Almirall or any Affiliate thereof and (ii) if, as a consequence of an infringement of a Third Party intellectual property
right, Almirall is not entitled to continue Developing and Commercializing the Licensed Product as provided in the Agreement, then Almirall shall be entitled to terminate the Agreement without prejudice to any other Almirall’s right under this
Agreement.

 6.5 Patent Term Extensions. The Parties shall cooperate with each other in obtaining patent term
extensions or restorations or supplemental protection certificates or their equivalents in any country in the Territory with respect to the Athenex Patent Rights where applicable and where reasonably requested by Almirall. Elections with respect to
obtaining such extension or supplemental protection certificates shall be made in the same manner and with the same relative priorities between the Parties as is applicable to the prosecution and maintenance of Patent Rights pursuant to
Section 6.2. 
 6.6 Patent Marking. Almirall shall mark, and shall require its Affiliates and its and their Sublicensees to mark, all Licensed
Products sold or distributed pursuant to this Agreement in accordance with the applicable patent statutes or regulations in the country or countries of manufacture and/or sale thereof, and in a manner reasonably consistent with ensuring maximum
enforceability of Patent Rights, and recovery of maximum available damages with respect to any infringement thereof, in such country. Upon Athenex’s reasonable request, Almirall shall provide Athenex with written notice of compliance with this
paragraph. 
 6.7 Patent Challenge. In the event Almirall, any Affiliate thereof, or any Sublicensee of either of the foregoing challenges the
validity, enforceability or scope of any of any Athenex Patent Right(s) or claims thereof by legal or administrative action or proceeding or otherwise, or, directly or indirectly, causes, enables, or assists any Third Party to undertake such a
challenge (a “Patent Challenge”) Athenex shall be entitled to terminate this Agreement on written notice to Almirall, provided, however, that Athenex shall not have the right to terminate this Agreement pursuant to this
Section 6.7 if such Patent has been brought by a Sublicensee and Almirall has used Commercially Reasonable Efforts to stop, fully withdraw or terminate such Patent Challenge. 

6.8 Trademarks. Almirall, its Affiliates, and its and their Sublicensees may, in their sole discretion, select Trademarks for use in the
Territory and, subject to Section 8.3(d), shall own all such Trademarks (such Trademarks, “Almirall Trademarks”). To the extent Almirall, its Affiliates, and Sublicensees pursue Trademarks Almirall, its Affiliates, and its and
their Sublicensees shall, as between the Parties, have the sole responsibility for the filing, prosecution and maintenance of registrations of such Trademarks, at their sole expense. For this purposes, Almirall shall be responsible for proposing and
choosing Trademark(s) for the Licensed Products in the Field in the Territory, and Almirall shall not submit any Trade Name(s) for approval which have not first been reviewed and commented on by Athenex and the Joint Steering Committee. Almirall
shall conduct reasonably customary market research with physicians that indicates that all Trademark(s) is(are) not materially confusing or otherwise materially misleading and will obtain reasonably appropriate
back-up documentation regarding the same. Both Parties shall use the Trademark(s) determined pursuant to the foregoing sentence in their Drug Approval Applications of Licensed Product in the Field in the
Territory unless otherwise decided by Almirall. Subject to the effects of Section 8.4(d) upon termination of this Agreement, Almirall shall own all worldwide right, title, and interest in and to all Trademark(s) approved for such Licensed
Product and intellectual property rights related thereto (including trade names and copyright), and Athenex shall, at Almirall’s expense, take any and all actions reasonably requested by Almirall in furtherance of the foregoing. All Trademarks
(including tradenames) shall be part of Almirall Intellectual Property. Again, for certainty, any use of Almirall Trademarks by Athenex, its Affiliates, or their licensees and Sublicensees will be subject to Almirall prior written consent.

(a) is known by the receiving Party at the time of its receipt, and not through a prior disclosure by the disclosing Party, as documented by
records; 
 (b) is or becomes properly in the public domain or knowledge without breach by either Party;

or benefit, of Proprietary Information received from the disclosing Party, as documented by records. 
 7.2 Permitted Disclosure of Proprietary
Information. Notwithstanding Section 7.1, a Party receiving Proprietary Information of another Party may disclose such Proprietary Information: 

(a) to governmental or other regulatory agencies in order to seek or obtain patents pursuant to this Agreement, or to gain approval to conduct

relevant to this Agreement or for due diligence in connection with the financing, licensing or acquisition of such Party (or such Party’s acquisition of or by, or merger with, a Third Party), provided that (i) advance written
consent is provided by the non-disclosing Party, (ii) each individual and entity to whom such Confidential Information is disclosed is bound in writing to non-use
and non-disclosure obligations (or in the case of attorneys or accountants, an equivalent professional duty of confidentiality) materially as restrictive as those set forth in this Agreement and (iii) the
Party making such disclosure shall be liable for such Third Parties’ compliance with such obligations. 
 7.3 Certain Disclosures. Except as set
forth in this Agreement or as required by Law, neither Party shall make any press release or other public announcement or other public disclosure to a Third Party concerning the existence of or terms of this Agreement, the subject matter of this
Agreement or the activities contemplated hereunder, without the prior written consent of the other Party, which consent shall include agreement upon the nature and text of such release, announcement, or other disclosure, and shall not be
unreasonably withheld or delayed. Athenex and Almirall, respectively, shall be entitled to issue the joint press releases set forth in Schedule 7.3 after 17:30 CET // 11:30 EST of the Execution Date. Either Party may make a subsequent public
disclosure of the contents of such press release in substantially similar form without further approval of the other Party; provided, however, that such subsequent disclosure is not inaccurate or misleading at the time of such subsequent disclosure.
With regard additional future press release, each Party agrees to provide to the other Party a copy of any such press release or other public announcement or disclosure as soon as reasonably practicable under the circumstances prior to its scheduled
release. Each Party shall have the right to expeditiously (but in any event within forty eight (48) hours) review and recommend changes to any such press release or other public announcement or disclosure; provided, however, that
such right of review and recommendation shall only apply for the first time that specific information is to be disclosed, and shall not apply to the subsequent disclosure of substantially similar information that has previously been disclosed unless
there have been material developments relating to any Licensed Product since the date of the previous disclosure; provided, further, that each Party shall, to the extent reasonably practicable, provide to the other Party reasonable
advance notice of any such subsequent disclosure. Without limiting the generality of any of the foregoing, it is understood that the Parties or their Affiliates may make disclosure of this Agreement and the terms hereof in accordance with the rules
and regulations of the SEC, other governmental authority, or securities exchange, may file this Agreement as an exhibit to any filing with the SEC, other governmental authority, or securities exchange, and may distribute any such filing in the
ordinary course of its business; provided, further, that to the maximum extent allowable by the rules and regulations of the SEC, other governmental authority, or securities exchange, and except as required by applicable Laws, Athenex
and Almirall shall use Commercially Reasonable Efforts to seek to redact any confidential information set forth in such filings, and each Party shall provide a draft of the redacted version of this Agreement to the other Party no less than five
(5) Business Days (or, if such timing is not reasonable practicable, as soon as reasonably possible) prior to filing with the SEC, other governmental authority, or securities exchange, and give reasonable consideration to the other Party’s

publication or an outline of the oral disclosure at least fifteen (15) days prior to planned submission or presentation for the receiving Party to make, if needed, reasonable comments thereof. The delivery Party shall take due consideration to
the comments provided by the other Party. No publication will be permitted without the affected Party prior’s written consent of such publication may negatively affect the rights or obligations or the reasonable commercial interest of the other
Party. 
 7.5 Publicity. Except as otherwise provided in this Agreement or required by law or regulation, no Party will originate any news release or
other public announcement, written or oral, whether in the public press, stockholders’ reports or otherwise, relating to this Agreement or to any sublicense under this Agreement, or to the performance under this Agreement or under any
sublicense under this Agreement, without the prior written approval of the other Party, which approval will not be unreasonably withheld or delayed; provided that the foregoing shall not restrict disclosures required by Law or the rules of any
applicable securities exchange, or made in connection with any filing of information or materials with a stock exchange or the SEC or any stockholders’ letter to private investors, which shall be governed by Section 7.3 above. 

ARTICLE 8 
 TERM AND
TERMINATION 
 8.1 Term and Expiration. This Agreement shall be binding on the Parties as of the Clearance Date, provided that Articles 1A and 10
(and the defined terms necessary therefor) shall be effective and binding on the Parties beginning on the Execution Date. Thereafter, unless terminated earlier pursuant to Section 8.2 below, this Agreement shall continue in full force and
effect for the entire commercial life of the Licensed Product on a country by country basis (the “Agreement Term”). For clarity, “entire commercial life of the Licensed Products” shall be understood as the moment in which
Almirall decides to stop continue commercializing the Licensed Products because at Almirall’s sole discretion, the Licensed Products do not have sufficient economic value in the market as to compensate Commercialization’s costs. At the
expiry of the Royalty Term with respect to a Licensed Product in a country of the Territory the licenses granted to Almirall and Aqua hereunder shall become irrevocable, fully paid up and royalty free with respect to such Licensed Product in such
country. 
 8.2 Early Termination of Agreement Term. 

(a) Termination by Almirall. 

(i) Almirall may terminate this Agreement, in its entirety or with respect to any particular country in the Territory, in its
sole discretion upon not less than six (6) months prior written notice of termination provided any time after the Clearance Date. 

(ii) This Agreement may terminate as set forth in Section 4.2(a). 

  
 59 









 EXECUTION DRAFT 
  

 (iii) Almirall may terminate this Agreement, immediately upon written notice
to Athenex, (z) if the Licensed Products may not be marketed in the Territory due to significant safety reasons; (y) in the event the Regulatory Approval for the Licensed Product is finally and irrevocably denied and rejected
by the applicable Regulatory Authority in the Territory (x) in the event the Product Label is materially less favorable than the Product Label submitted to the Regulatory Authorities, in a manner that is expected to materially adversely
affect the commercial value of the Product. 
 (b) Termination by either Party. Either Party may, without prejudice to any other
remedies available to it under this Agreement or at law or in equity, terminate this Agreement prior to expiration of the Agreement Term in the event that the other Party (as used in this subsection, the “Breaching Party”) has
materially breached or defaulted in the performance of any of its obligations hereunder (including a breach of the representations and warranties set forth in this Agreement and including a failure to meet the timelines set out in the Development
Plan in a way that the commercial value of the Licensed Product as of the Execution Date has materially decreased and where materiality should be determined in the context of the entire Agreement), and has not cured such breach within sixty
(60) days after written notice of such breach is provided to the Breaching Party, which notice shall specify the nature of the breach and demand its cure, provided, however, that if such breach is not capable of being cured within the stated
period and the Breaching Party uses Commercially Reasonable Efforts to cure such breach during such period and presents a mutually agreeable remediation plan for such breach, this Agreement shall not terminate and the cure period shall be extended
for such period provided in the mutually agreed upon remediation plan as long as the Breaching Party continues to use Commercially Reasonable Efforts to pursue the cure as provided in such remediation plan. In the event the Parties dispute in good
faith the existence of a material breach or a Party’s diligence in attempting to cure a material breach, termination of this Agreement shall not be deemed to occur unless and until such dispute has been referred for resolution in accordance
with Section 10.8 hereof, material breach of the Agreement or failure to make diligent efforts to cure such breach has been established by an arbitration thereunder and, if such breach can be cured by the payment of money or the taking of
specific remedial actions, the Breaching Party does not pay the amount so determined to be due within ten (10) calendar days of receipt of the arbitration decision or otherwise diligently undertake and complete such remedial actions within the
timeframe established by such arbitration decision. The right of either Party to terminate this Agreement as provided in this Section 8.2(b) shall not be affected in any way by such Party’s waiver or failure to take action with respect to
any previous breach or default. 
 (c) Other Termination. All licenses granted under or pursuant to this Agreement are, and shall
otherwise be deemed to be, for purposes of Section 365(n) of the U.S. Bankruptcy Code or any analogous provisions in any other country or jurisdiction, licenses of rights to “intellectual property” as defined under Section 101 of
the U.S. Bankruptcy Code. The Parties agree that Almirall and Aqua, as applicable, as licensee of such rights under this Agreement, shall retain and may fully exercise all of its rights and elections under the U.S. Bankruptcy Code or any analogous
provisions in any other country or jurisdiction. The Parties further agree that, in the event of the commencement of a bankruptcy proceeding by or against Athenex under the U.S. Bankruptcy Code or any analogous provisions in any other country or
jurisdiction which proceeding is not terminated or withdrawn within ninety (90) days after such commencement, Athenex shall within five (5) working days deliver to Almirall a complete set of the Manufacturing Know How.

 8.3 Effects of Certain Terminations by Almirall. If Almirall is entitled to terminate this Agreement
pursuant to Section 8.2(b), Almirall may elect to either terminate this Agreement in its entirety (in which case Section 8.4 will entirely apply) or elect to continue this Agreement, subject to the following provisions which shall be
effective upon Almirall’s notice of such election: 
 (a) To the extent Athenex’s failure to perform its obligations under this
Agreement gives rise to a right of termination by Almirall and Athenex’s insolvency, as applicable, directly impacts Athenex’s ability to perform its obligations in accordance with the terms of this Agreement (in each case such affected
activity the “Breaching Activity”), Athenex shall as soon as practicable upon becoming aware of such failure, inform Almirall that it will be unable to fulfill such obligation and the duration for which Athenex reasonably expects to
continue to be unable to perform such Breaching Activity. If it is reasonably expected that Athenex will be unable to perform the Breaching Activity for a significant period of time, Almirall will be entitled to perform such Breaching Activity for
the period that Athenex has notified Almirall it will be unable to so perform (or if Athenex has failed to provide such notice, for a period determined by Almirall in a Commercially Reasonable manner) plus such additional time period as Almirall
reasonably requires to fulfill its commitments under contracts with Third Party subcontractors engaged to perform the relevant activities and to smoothly transition such activities back to Athenex (the
“Step-in Period”). In such a case, Almirall will be entitled to receive from Athenex by means of reducing the Commercial Milestones under Section 4.3 and the Royalties under
Section 4.5 or by any other reasonable reimbursement process established in good faith by the Parties the amount necessary to cover the entire costs incurred by Almirall in performing the Breaching Activity during the Step-in Period multiplied by one and one-half (i.e. one and one-half times Almirall costs). Almirall shall be granted with the
necessary licenses under the Athenex Intellectual Property during the Step-in Period to perform the Breaching Activity. 

(b) Athenex shall furnish Almirall during a reasonable period with reasonable cooperation to assure a smooth transition of the Breaching
Activity then being conducted or performed by Athenex which Almirall determines to continue in accordance with this Section 8.3 and in compliance with applicable Laws and ethical guidelines applicable to the transfer or termination of any such
activities; 
 (c) Athenex will not be entitled to exercise the Athenex Co-Promotion right governed
in Article 3B; 
 (d) Except as expressly provided in this Section 8.3, this Agreement shall remain in full force and effect, and all
payment obligations of the Parties shall continue to apply; 
 (e) Athenex shall inform Almirall within a reasonable period before expiration
of the Step-in Period (a) if Athenex will continue to be unable to perform the Breaching Activity or (b) if, upon such expiration of the Step-in Period,
Athenex will be able to resume performing such Breaching Activity. If Athenex will continue to be unable to perform the Breaching Activity 

  
 61 









 EXECUTION DRAFT 
  

 
after the Step-in Period, the Step-in Period will be extended for so long as is reasonably necessary for Athenex to
be able to resume the Breaching Activity, plus such additional period as Almirall reasonably requires to fulfill its commitments under contracts with Third Party subcontractors engaged to perform the relevant activities and to smoothly transition
such activities back to Athenex. If upon expiration of such Step-in Period, Athenex will be able to re-commence its obligations under the Agreement, Almirall shall
furnish Athenex during a reasonable period with reasonable cooperation to assure a smooth transition of such activities and in compliance with applicable Laws and ethical guidelines applicable to the transfer or termination of any such activities.
Once Athenex starts to perform such activities, the rights and obligations of the Parties under the Agreement will continue to be executed by the Parties as they were performed prior to the events giving rise to Almirall ’s rights under this
Section 8.3. 
 (f) Should Almirall decides to terminate the Agreement due to a breach of the representations and warranties granted by
Athenex under Section 5 with respect to the Licensed Product (which breach of such representation and warranty (i) is proven by Almirall to be the result of a misrepresentation or falsehood made by Athenex or Athenex’s withholding of
material information known to Athenex after reasonable due enquiry and (ii) shall result in the impossibility for Almirall to Commercialize the Licensed Product in accordance with the Agreement) identified before the First Commercial Sale,
Almirall shall be entitled to claim as damages and Athenex shall indemnify Almirall with damages equivalent to the aggregate of the amounts paid by Almirall to Athenex in accordance with Sections 4.1 and 4.2. 

8.4 Effect Termination; Survival. 
 (a)
Termination of this Agreement, in whole or in part, shall not relieve the Parties of any obligation accruing prior to such termination, including all accrued payment obligations arising under Article 4 hereof. In addition to any other
provisions of this Agreement which reasonably by their terms continue after the termination of this Agreement, the provisions of Articles 1, 7, and 10 and Sections 2.3, 2.4(b), 3.3(g) (with respect to Section 2.3), 3.7, 4.6, 4.7, 4.8, 5.3,
8.1, 8.3, 8.4, 9.1, 9.2, 9.3, 9.4, 9.5, 9.6 (for the period specified), and 9.7 shall survive the termination of this Agreement and shall continue in effect after the date of such termination. Any early termination of this Agreement (in whole or in
part) shall be without prejudice to the rights of any Party against the other accrued or accruing under this Agreement prior to such termination. Except as expressly set forth herein, the rights to terminate as set forth herein shall be in addition
to all other rights and remedies available under this Agreement, at law, or in equity, or otherwise. 
 (b) Payments of amounts owing to a
Party under this Agreement as of its termination shall be due and payable either (i) to the extent such amounts can be calculated and a fixed sum determined at the time of termination of this Agreement, upon the earlier of (x) the due date
for such payment established under this Agreement or (y) thirty (30) days after the date of such termination or (ii) to the extent such amounts cannot be calculated and a fixed sum determined at the time of termination of this
Agreement, thirty (30) days after the date at which such amounts can be calculated and a fixed sum is mutually determined. Any payment owing to Athenex hereunder will be conditional upon and/or subject to Almirall’s available rights
(i) in the event of material breach of this Agreement by Athenex, including offsetting damages; and/or (ii) in the case of any payment made under Section 4.2(a), to reimbursement (whether or not under the first demand bank guarantee
for which Section 4.2(b) provides).

 (c) Either Party shall be entitled (i) to
set-off any claims it may have under this Agreement and/or any of the Ancillary Agreements against any claims any other Party may have under this Agreement and/or any of the Ancillary Agreements and
(ii) to refuse to perform any obligation it may have under this Agreement and/or any of the other Supply Agreements on the grounds that it has a right of retention under this Agreement. 

(d) Subject to the payment of all amounts required hereunder, in the event of termination of this Agreement by Almirall under
Section 8.2(a) and 8.2(b), Almirall and its Affiliates shall have the right to sell or otherwise dispose of the stock of any Licensed Product subject to this Agreement and to such termination on hand or in process of manufacture as of such
termination. Within thirty (30) days after the effective date of termination of this Agreement, Almirall shall notify Athenex of the amount of each applicable Licensed Product Almirall and its Affiliates then have on hand or in the process of
manufacture and shall have the right, for a period of twelve (12) months following such termination, to sell such inventory in the Territory (except with respect to any country in the Territory in which any Licensed Product has been withdrawn
or there is no Regulatory Approval), until all of it is sold; provided, however, the terms and conditions of this Agreement (including payments due under Article 4) shall apply with respect to the sale of such Licensed Product. Almirall shall notify
Athenex of any remaining quantities of such Licensed Product not sold at the end of such twelve (12) month period and, at Athenex’s written given election, such remaining Licensed Product shall be (i) destroyed by Almirall at
Almirall’s cost, (ii) sold to Athenex at Almirall’s reasonable, documented, direct cost of procuring such Licensed Product (which cost shall be provided to Athenex prior to it being required to make such election), or (iii) sold
by Almirall and its Affiliates to customers in the Territory following such twelve (12) months period. 
 (e) Upon termination of this
Agreement by Almirall under Section 8.2(a) or by Athenex and Almirall under Section 8.2(b) (and, with respect to any termination of this Agreement by Almirall with respect to any particular country, only with respect to such country), a
copy of all Data, Know-How, Patent Rights, Almirall Trademarks, and other information in Almirall’s and its Affiliates’ possession or Control concerning Licensed Products, Licensed Product
inventory and work-in-process, Product-Related Materials, regulatory filings, submissions, approvals, and marketing, pricing, and/or reimbursement authorizations or
approvals (including Pricing Approvals) with respect to, in the case of all of the foregoing, Licensed Products must be transferred to Athenex within sixty (60) days of termination, and, if, as, and to the extent subsequently requested in
writing by Athenex and not necessary to enable Almirall to exercise its rights under Section 8.4(d), Almirall (and, as applicable, Almirall shall procure that its Affiliates and its and their Sublicensees) (i) shall transfer and assign,
and hereby assigns, to Athenex or its designee (or have reissued in the name of Athenex or its designee, if applicable) all right, title, and interest in all regulatory filings, submissions, or applications, INDs, Drug Approval Applications,
Regulatory Approvals, Pricing Approvals, and Product-Related Materials possessed, owned, controlled, filed, or submitted by or on behalf of Almirall, any Affiliate thereof, or any of its or their Sublicensees that relate to any Licensed Products,
free and clear of all liens, claims, and encumbrances (other than Almirall’s right, title or interest in or to any Almirall Know-How, Almirall Patent Rights, Almirall Trademarks or any other Almirall

exclusive, world-wide license, with rights of sublicense (through multiple tiers), under the Almirall Trademarks, to develop, make, have made, use, sell, offer for sale, import, and export, market and promote Compounds, Licensed Products (including
but not limited to all Licensed Products Commercialized or under Development by Almirall or any of its Affiliates or its or their Sublicensees as of the effective date of termination), or any other products incorporating any Compound;
(iii) shall, subject to Section 8.3(c), sell and deliver the inventory of Licensed Products and work-in-process to Athenex, and Athenex shall, within thirty
(30) days of such delivery, pay Almirall the corresponding Supply Price paid by Almirall to Athenex for such inventory or with regard to the work-in-process agreed
the price agreed upon by the Parties that shall not exceed such Almirall’s reasonable, documented, direct cost of procuring such work-in-process delivered to
Athenex, and (iv) shall provide Athenex all information requested thereby concerning any manufacturing, supplier, distributor, research, development, clinical study, or other contracts concerning the Development, manufacture, or
Commercialization of Licensed Products in the Field in the Territory entered into by Almirall or its Affiliates with Third Parties (“Product-Related Contracts”) (to the extent permitted in accordance with the terms of the
Product-Related Contracts) and, if and as subsequently requested by Athenex, (X) assign such Product-Related Contracts to Athenex (to the extent assignable in accordance with their terms or consent to such assignment is obtained by Almirall
pursuant to the following clause (Y)), (Y) use Commercially Reasonable Efforts to obtain Third Parties’ consent to such assignment to the extent not permitted by the terms of such agreements, in order to enable such assignment as contemplated
by clause (X). The licenses granted under clause (ii) above shall, in the case of any termination by Athenex under Section 8.2(b), be fully-paid and royalty-free; Athenex shall, in the case of all other terminations, pay Almirall a
reasonable royalty with respect to the exercise of such rights in a manner and in an amount to be negotiated in good faith and mutually agreed upon by the Parties taking into account the value of the intellectual property subject to such license,
provided that, if the Parties are unable to agree on the manner and amount of such payments within one hundred eighty (180) days of such termination, the Parties agree to engage an independent certified public accounting firm of recognized
standing (i.e. one of the so-named Big Four accounting firms provided that it is not the then auditing firm of any of the Parties), for resolution and any determination reached thereunder shall be binding on
the Parties. Almirall shall take (and cause its Affiliates and its and their Sublicensees to take) such other actions and execute such other documents as may be necessary to effect the transfers, licenses, and assignments contemplated
hereunder. The Parties agree that, in the event of any termination of this Agreement by Almirall under Section 8.2(a) with respect to one or more country(ies) in the Territory (and not in its entirety), the provisions of this
Section 8.4(e) shall apply only with respect to the country(ies) that are the subject of such termination. 
 (f) The extent permitted
by applicable Law, in the event of the commencement of a bankruptcy proceeding by or against Athenex or Almirall under the U.S. Bankruptcy Code or any analogous provisions in any other country or jurisdiction, which proceeding is not terminated or
withdrawn within ninety (90) days after such commencement, the Party in bankruptcy situation shall be entitled (unless the other Party elects to continue to perform all of its obligations under this Agreement) to a complete duplicate of (or

material breach of any of Almirall’s obligations, representations, warranties or covenants under this Agreement. 
 9.4 Indemnification
Procedure. 
 (a) Each Party shall promptly notify the other Party in writing of any Claim subject to indemnification under
Section 9.2 or 9.3. Concurrent with the provision of notice pursuant to this Section 9.4(a), the party seeking indemnification (the “Indemnified Party”) shall provide to the other Party copies of any complaint, summons,
subpoena or other court filings or correspondence related to such Claim and will give such other information with respect thereto as the other Party (the “Indemnifying Party”) shall reasonably request. The Indemnifying Party and
Indemnified Party shall promptly meet to discuss how to respond to such Claim. Failure to provide prompt notice shall not relieve any Party of the duty to defend, indemnify, or hold harmless unless and to the extent such failure materially
prejudices the defense or settlement of any matter. Each Party agrees that it will use Commercially Reasonable Efforts to minimize the burdens of the litigation on witnesses and on the ongoing business of the Indemnified Parties, including making
reasonable accommodations to witnesses’ schedules when possible and seeking appropriate protective orders limiting the duration and/or location of depositions. 

(b) Should an allegedly Indemnifying Party with respect to a Claim or Loss dispute that any Claim, Loss, or portion of a Claim or Loss
(“Disputed Claim”) of which it receives notice pursuant to Section 9.4(a), is an indemnified Claim or Loss, it shall so notify the other Party providing written notice in sufficient time to permit such other Party to retain
counsel and timely appear, answer and/or move in any such action. In such event, such other Party shall be entitled to defend against such Claim or Loss; provided, however, that such other Party shall not settle any Claim or Loss which
it contends is an indemnified Claim or Loss without providing the Indemnifying Party, to the extent reasonably practicable, ten (10) Business Days’ notice prior to any such settlement and a reasonable opportunity to assume the defense and
indemnification of such Claim or Loss pursuant to this Agreement. If it is determined that a Disputed Claim is subject to indemnification under this Agreement, the Indemnifying Party will reimburse the costs and expenses, including reasonable
attorneys’ fees, of the Indemnified Party and any Losses suffered by the Indemnified Party with respect thereto.

 9.5 Settlement of Indemnified Claims. The Indemnifying Party under Sections 9.2 or 9.3, as
applicable, shall have the sole authority to settle any Indemnified Claim without the consent of the other Party; provided, however, that, notwithstanding the foregoing, an Indemnifying Party shall not, without the written consent of
the other Party, as part of any settlement or compromise of any Claim or Loss subject to Section 9.2 or 9.3, respectively, (i) admit to fault, wrongdoing, or nonindemnified liability on the part of any Athenex Indemnified Party or Almirall
Indemnified Party, respectively; (ii) agree to an injunction against any Athenex Indemnified Party or Almirall Indemnified Party, respectively; or (iii) settle any matter in a manner that adversely affects any of the Athenex Intellectual
Property or materially and adversely affects either Party’s ability to Develop, manufacture, , use, or Commercialize Compound or Licensed Products, without the prior written consent of the Indemnified Party. The Parties further agree that as
part of the settlement of any Indemnified Claim, an Indemnifying Party shall obtain a full, complete and unconditional release from the claimant on behalf of the Indemnified Parties with respect to the applicable Claim or Loss to the extent it is
subject to indemnification hereunder. 
 9.6 Insurance. 

(a) Each Party shall maintain, commencing as of the Clearance Date, and maintained during the Term and during the ten (10) years following
the expiration or early termination of the Agreement, commercial general liability insurance (including coverage for product liability, contractual liability, bodily injury, property damage and personal injury), in form and substance reasonably
satisfactory to the other Party and in accordance with levels of coverage and other terms as are reasonable and customary for a pharmaceutical company manufacturing and selling a comparable product, but in any event not less than reasonable U.S.
pharmaceutical industry standards, with, no later than the initial commercial sale of Licensed Product hereunder, minimum limits of $10,000,000 per occurrence and $10,000,000 in the aggregate (the “Insurance”). If such Insurance is
written on a claims-made form, it shall continue for five (5) years after it has ceased all commercial sale, distribution or use of any Product. The Insurance may have retroactive date to or coinciding with the Clearance Date. 

(b) Such Insurance shall insure against all liability arising out of the manufacture, use, sale, distribution, or marketing of all Licensed
Products. The Insurance shall be primary and non-contributory to any insurance maintained by the other Party. During the Agreement Term, neither Party shall permit such Insurance to be reduced, expired,
materially amended or canceled during the period of the Insurance and/or the Agreement without reasonable prior written notice that shall be sent by registered mail to the other Party. Upon request each Party shall provide certificates of insurance
to the other Party evidencing the coverage specified herein. 
 (c) Except as expressly stated herein, a Party’s liability to the other
is in no way limited to the extent of the Party’s insurance coverage. 
 (d) The Insurance shall be valid in any location worldwide
regarding the activities performed by each Party hereunder (including worldwide jurisdictions) for any destination or lawsuit which will be served against the other Party.

 (e) Athenex and its Affiliates shall be named as additional insureds under the Insurance.

 9.7 Limitation of Liability. IN NO EVENT SHALL EITHER PARTY BE LIABLE TO THE OTHER OR ANY OF ITS AFFILIATES FOR ANY CONSEQUENTIAL, INCIDENTAL,
INDIRECT, SPECIAL, PUNITIVE OR EXEMPLARY DAMAGES (INCLUDING LOST PROFITS, BUSINESS OR GOODWILL) SUFFERED OR INCURRED BY SUCH OTHER PARTY OR ITS AFFILIATES, WHETHER BASED UPON A CLAIM OR ACTION OF CONTRACT, WARRANTY, NEGLIGENCE, STRICT LIABILITY OR
OTHER TORT, OR OTHERWISE, ARISING OUT OF THIS AGREEMENT. THE FOREGOING SENTENCE SHALL NOT (I) LIMIT THE OBLIGATIONS OF EITHER PARTY TO INDEMNIFY THE OTHER PARTY FROM AND AGAINST THIRD PARTY CLAIMS UNDER THIS ARTICLE 9 OR (II) APPLY TO
CLAIMS OF PATENT INFRINGEMENT OR BREACHES OF ARTICLE 7. 
 ARTICLE 10 

MISCELLANEOUS 
 10.1 Force Majeure.
Neither Party shall be held liable or responsible to the other Party nor be deemed to have defaulted under or breached the Agreement for failure or delay in fulfilling or performing any term of the Agreement during the period of time when such
failure or delay is caused by or results from events beyond the reasonable control of a Party, which may include, but shall not be limited to, fire, flood, earthquake, explosion, storm, blockage, embargo, war, acts of war (whether war be declared or
not), terrorism, insurrection, riot, civil commotion, strike, lockout or other labor disturbance, failure of public utilities or common carriers, act of God, or act, omission, or delay in acting by any governmental authority or the other Party,
provided that this Section 10.1 shall not apply to any payment obligation under this Agreement. The affected Party shall notify the other Party of such force majeure circumstances as soon as reasonably practicable. 

10.2 Assignment. The Agreement may not be assigned or otherwise transferred, nor may any right or obligation hereunder be assigned or transferred, by a
Party without the prior written consent of the other Parties, provided however, that Athenex, on the one hand, or Aqua and Almirall on the other hand, may assign this Agreement without such consent (i) to an Affiliate of the assigning
Party(ies) (provided that the assigning Party(ies) shall continue to remain principal obligor for any and all obligations and liabilities assigned to such Affiliate under the terms of this Agreement) or (ii) in connection with the transfer or
sale of all or substantially all of its business or assets (or that portion thereof related to the subject matter hereof) or in the event of a merger, or consolidation if(a) in the case of an assignment under clause (i) or (ii) above, the
assignee of the Agreement is not located in a Tax Haven or in a country that is reasonably likely to have a net material and adverse effect on the tax applicable to any payment under the Agreement or under the Supply Agreement and owed by a non-assigning Party, as determined immediately prior to such assignment, in which case the affected other Party’s(ies’) prior written consent(s) is(are) needed for such assignment, but which consent will
not be unreasonably withheld, conditioned or delayed and (b) in the case of an assignment pursuant to clause (ii) above, the assigning Party ensures that the successor entity agrees, and the successor entity agrees, to assume the assigning
Party’s ongoing responsibilities and obligations under this Agreement, 

  
 68 









 EXECUTION DRAFT 
  

 
provided that, in the case of an assignment pursuant to clause (ii) above, if the successor entity is not a Qualified Assignee, such successor entity must reasonably be able to assume and
fulfill the assigning Party’s ongoing obligations and responsibilities under the Agreement, as reasonably determined by the other Party in good faith, such determination not to be unreasonably withheld. Any assignment permitted under this
Agreement shall not relieve the transferring Party of its responsibilities for performance of its obligations under this Agreement as a primary obligor. This Agreement shall be binding upon and inure to the benefit of the successors and assigns of
the Parties. Any assignment not in accordance with this Agreement shall be void. Notwithstanding anything to the contrary, Aqua and Almirall shall not be entitled to separately assign their interests under this Agreement under any circumstance
without Athenex’s prior written consent. For purposes of this Section 10.2, “Tax Haven” means a jurisdiction listed in Schedule 10.2. 

10.3 Severability. In the event that any of the provisions contained in this Agreement are held invalid, illegal or unenforceable in any respect, the
validity, legality and enforceability of the remaining provisions contained herein shall not in any way be affected or impaired thereby, unless the absence of the invalidated provision(s) adversely affects the substantive rights of the Parties. In
such event, the Parties covenant and agree to renegotiate any such term, covenant or application thereof in good faith in order to provide a reasonably acceptable alternative to the term, covenant or condition of this Agreement or the application
thereof that is invalid or unenforceable, it being the intent of the Parties that the basic purposes of this Agreement are to be effectuated. 
 10.4

 EXECUTION DRAFT 
  

 10.6 Further Assurances. Each of the Parties shall take such further actions as shall be necessary or
desirable in order to effectuate the respective rights and obligations hereunder. 
 10.7 Applicable Law, Venue. This Agreement shall be governed by
the laws of the Laws of England and Wales , without regards to its conflicts of law provisions. The United Nations Convention on Contracts for the International Sale of Goods shall not apply in any action, suit or proceeding arising out of or
relating to this Agreement or the Supply Agreement. 
 10.8 Dispute Resolution. In the event that a dispute arises between the Parties in the course
of this Agreement, other than with respect to a decision that is the subject of the Joint Steering Committee’s decision-making authority and for which Section 3.6(c) does not specifically refer the final determination of such decision to
this Section 10.8, the dispute will be referred to the attention of the Chief Executive Officer of Athenex and the Chief Executive Officer of Almirall (the “Executive Officers”). The Executive Officers will meet as soon as
reasonably possible thereafter and in good faith attempt to resolve such dispute. If, within thirty (30) calendar days after referral of such dispute to the Executive Officers by either Party, the Executive Officers are unable to resolve such
dispute, with the exception of disputes relating to the validity, enforceability and infringement of Intellectual Property (which disputes must be tried before a court of competent jurisdiction), either Party will have the right to have the dispute
resolved by binding arbitration, initiated by either Party on fifteen (15) Business Days notice to the other Party following the expiration of the thirty (30) calendar day period referenced above (the “Initiation Notice”),
under the Rules of Arbitration of the International Chamber of Commerce (“ICC”) then pertaining, except where those rules conflict with this provision, in which case this provision controls, applying the laws of England and Wales,
without regard to its conflicts of law provisions, before three (3) independent, neutral arbitrators experienced in the pharmaceutical industry and licensing transactions in such industry. Athenex and Almirall shall each be entitled to select
one (1) such arbitrator, with the two (2) such arbitrators so selected selecting the third (3rd) such arbitrator. In the event either Party fails to select its arbitrator in accordance
with the forgoing within fifteen (15) Business Days of the Initiation Notice, the arbitrator selected by the other Party within such fifteen (15) Business Day period shall be entitled to select such arbitrator, and, to the extent all three
such arbitrators are not selected within 30 calendar days of the Initiation Notice, such arbitrators shall be appointed by the International Court of Arbitration of the ICC. Prior to the commencement of hearings, each of the arbitrators appointed
must provide an oath of undertaking of impartiality. The decision of the arbitrators will be final and binding on the Parties, and judgment upon the award or determination rendered by the arbitrators may be entered and enforced in any court of
competent jurisdiction. The arbitration shall be conducted in English, and the place of arbitration shall be Geneva, Switzerland. Each Party shall bear its own expenses and an equal share of the reasonable, documented expenses of the arbitration
panel and any fees required by ICC to submit such matter to arbitration, unless the panel determines that any such fees or expenses are to be paid by the non-prevailing Party, and the Parties hereby agree that
the panel shall be entitled and empowered to make such a determination. Notwithstanding anything to the contrary in this Agreement, either Party will have the right to seek injunctive or equitable relief, and in the case of disputes relating to the
validity, enforceability and infringement of Intellectual Property, may also seek any other available remedy, in any court of competent jurisdiction as may be available to such Party under the laws and rules applicable in such jurisdiction with
respect to any matters arising out of this Agreement. Except to the extent necessary to confirm an award or as may be required by Law, 

  
 71 









 EXECUTION DRAFT 
  

 
neither a Party nor an arbitrator may disclose the existence, content, or results of arbitration without the prior written consent of both Parties. The Parties agree that, in the event of a good
faith dispute over the nature or quality of performance under this Agreement, neither Party may terminate this Agreement until final resolution of the dispute through arbitration or other judicial determination. The Parties further agree that any
payments made pursuant to this Agreement pending resolution of the dispute shall be refunded if an arbitrator or court determines that such payments are not due. 

10.9 Entire Agreement. This Agreement, including the exhibits and schedules hereto, contains the entire understanding of the Parties with respect to the
subject matter. All express or implied agreements and understandings, either oral or written, heretofore made, including any offering letters, letters of intent, or term sheets, are expressly superseded by this Agreement. This Agreement may be
amended, or any term hereof modified, only by a written instrument duly executed by all Parties hereto. 
 10.10 Independent Contractors. It is
expressly agreed that the Parties shall be independent contractors and that the relationship between the Parties shall not constitute a partnership, joint venture or agency. Neither Party shall have the authority to make any statements,
representations or commitments of any kind, or to take any action, which shall be binding on the other Party, without the prior consent of such other Party. 

10.11 Waiver. The waiver by a Party hereto of any right hereunder or the failure to perform or of a breach by another Party shall not be deemed a waiver
of any other right hereunder or of any other breach or failure by said other Party whether of a similar nature or otherwise. 
 10.12 Headings;
References. The captions to the several Articles and Sections hereof are not a part of the Agreement, but are merely guides or labels to assist in locating and reading the several Articles and Sections hereof. Any reference in this Agreement to
an Article, Exhibit, Schedule or Section shall, unless otherwise specifically provided, be to an Article, Exhibit, Schedule or Section of this Agreement. The words “including”, “includes” and “such as” are used in their
non-limiting sense and have the same meaning as “including without limitation” and “including but not limited to.” “Hereunder” and “hereto” means under or pursuant to
any provision of this Agreement. 
 10.13 Interpretation. Both Parties have had the opportunity to have this Agreement reviewed by an attorney;
therefore, neither this Agreement nor any provision hereof shall be construed against the drafter of this Agreement. 
 10.14 Counterparts. The
Agreement may be executed in two or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. Signatures to the Agreement transmitted by email in “portable document

Licensed Product to ALMIRALL during the full commercial life of the Licensed Product. ALMIRALL will be entitled to be supplied from a Third Party to the extent, and provided that, it is legally possible after expiry of the corresponding ATHENEX
patents covering the Licensed Product. 

  

	 	1.2.	ATHENEX shall supply the Licensed Product to ALMIRALL, at least, not later than three (3) months before the expected date to obtain the corresponding regulatory approvals in the Territory (such date as detailed in
the timelines agreed in the Development Plan). 

  

	 	1.3.	ATHENEX shall supply the Licensed Product to ALMIRALL in its finished, packaged and labelled form ready for commercialization and use by final users, at the supply price detailed in Section 6 (“Supply
Price”). 

  

	 	1.4.	ALMIRALL will be entitled to validate one of its manufacturing facilities as alternative Licensed Product manufacturer of finished product, whether directly or indirectly through an Affiliate or a Third Party. ATHENEX

such shortage. 

  

	 	1.7.	ATHENEX shall not be entitled to make changes in the manufacturing process or the primary or secondary packaging of the Licensed Product or in the Licensed Product Specifications (to be agreed) in the Territory without

Press release 

Barcelona,                

December 12th 2017 

Almirall and Athenex announce strategic partnership for the treatment of actinic keratosis 

 

	 	•	 	Almirall and Athenex have entered into a strategic partnership to develop and commercialize KX2-391 in the United States and Europe 


 

	 	•	 	KX2-391 is a first-in-class topical treatment currently in Phase III development that will
strengthen Almirall’s actinic keratosis franchise and dermatology market leadership 

  

	 	•	 	This move represents a major step for Almirall in adding to its pipeline highly innovative drugs in an area of unmet medical need and for Athenex in broadening its global reach through KX2-391 

  

	 	•	 	Athenex will receive an upfront fee, development and sales milestones, and royalty payments with a scheme that will incentivize a strong partnership going forward 


BARCELONA, Spain and BUFFALO, N.Y., December 11, 2017 — Almirall, S.A (ALM), a global skin-health focused pharmaceutical company, today
announced an agreement with Athenex, Inc. (Nasdaq:ATNX), a global biopharmaceutical company dedicated to the discovery, development and commercialization of novel therapies for the treatment of cancer and related conditions, to further
develop and commercialize KX2-391 for the treatment of actinic keratosis and other skin conditions. 

Subject to the terms and conditions of the License Agreement, Athenex will grant to Almirall an exclusive license under the Athenex IP to research,
develop and commercialize KX2-391 in the United States of America and European countries, including Russia. 
 KX2-391, also known as KX-01, is a first-in-class dual Src kinase and tubulin polymerization
inhibitor in Phase III development as a topical medicinal product for the treatment of actinic keratosis. Actinic keratosis is a common skin condition that is induced through ultra-violet light damage, resulting in patches of thick, scaly, or crusty
skin. Left untreated, the lesions have risk of progression to squamous cell carcinoma and consequently treatment by a dermatologist is recommended. Actinic keratosis is the most common pre-cancerous condition
in dermatology and it affects more than 55 million Americans. Actinic keratosis constitutes between 14-29% of dermatologist visits in the USA1. 

  
 87 








 Under the terms of the partnership agreement, Athenex will receive an
up-front fee and near-term payments of up to USD $55 million. Athenex will also be eligible to receive launch and additional indications milestones for USD $65 million. In addition, there will be
sales performance milestones of KX2-391 estimated to be USD $155 million. Almirall will reward Athenex with additional sales milestones, should the sales exceed the currently projected amounts. In
addition, there will be tiered royalties starting at 15% based on annual net sales, with incremental increases in royalty rates with increased sales. 

Athenex will be responsible for conducting all preclinical and clinical studies up to US FDA approval. Almirall will employ its expertise to support the
development in Europe and also to commercialize the product in the defined territories. Milestones encourage the joint effort of Athenex and Almirall to develop additional indications and additional formulations. 

This transaction is subject to antitrust clearance by antitrust authorities. 

Peter Guenter, Chief Executive Officer, Almirall, commented, “We are pleased to enter this collaboration with Athenex, a Company dedicated to
the development of oncology focused products. We are very impressed by the Athenex team in their innovation and execution of drug development efforts and we look forward to partnering with them as we progress towards the development and
commercialization of this promising product. KX2-391 has the potential to change the standard of care of actinic keratosis. Today, many patients with AK remain undiagnosed or untreated, therefore, we believe
this product can become a game changer in the treatment of this disease. Our leadership in the field of actinic keratosis will complement the drug development expertise of Athenex. In addition, our partnership will be further strengthened by
researching and developing other potential indications in the field of dermatology. ” 
 Johnson Lau, Chief Executive Officer, Athenex,
stated, “Athenex is excited to partner with Almirall to further develop KX2-391 for actinic keratosis, one of our leading clinical candidates currently in the midst of Phase III registration studies.
Almirall is a leader in the field of medical treatment of actinic keratosis in both Europe and USA, and also a market leader in the field of dermatology. We are very impressed by the management team of Almirall and are very confident that this
partnership will create strong synergies and a platform for growth for both companies and our partnership going forward. Almirall’s experience in the US and Europe will be critical to develop and commercialize this product across the
territories for AK patients.”  
 Bhushan Hardas, Executive Vice President R&D and Chief Scientific Officer of Almirall added,
“By combining Athenex and Almirall drug development and regulatory expertise, and adding Almirall dermatology experience as well as our deep knowledge in actinic keratosis, we are confident that we will jointly be able to bring this exciting
novel treatment opportunity for patients with actinic keratosis to both the US and EU market. KX2-391 has a short treatment duration and potentially an excellent adverse event profile compared to some of the
current treatment options in actinic keratosis, with comparable efficacy.” 
 Rudolf Kwan, Chief Medical Officer, Athenex, said,
“Almirall has great scientific, regulatory and marketing experience globally in actinic keratosis, which, coupled together with our innovative drug discovery and clinical development will allow the speedy registration of this product and access
for patients in the licensed territories. Our Phase II clinical trial results of KX2-391 showing excellent efficacy in the topical treatment of actinic keratosis without major toxicities will be presented in
the upcoming American Academy of Dermatology meeting on February 17, 2018 in San Diego. After consultation with the FDA, we initiated our Phase III pivotal clinical trials which are progressing rapidly and meeting our aggressive
timelines.”

 About Athenex, Inc. 

Founded in 2003, Athenex, Inc. is a global clinical stage biopharmaceutical company dedicated to becoming a leader in the discovery and development of next
generation drugs for the treatment of cancer. Athenex is organized around three platforms, including an Oncology Innovation Platform, a Commercial Platform and a Global Supply Chain Platform. Athenex’s Oncology Innovation Platform generates
clinical candidates through an extensive understanding of kinases, including novel binding sites and human absorption biology, as well as through the application of Athenex’s proprietary research and selection processes in the lab. The
Company’s current clinical pipeline is derived from two different platform technologies Athenex calls Orascovery and Src Kinase Inhibition. The Orascovery platform is based on the novel oral
P-glycoprotein pump inhibitor molecule HM30181A, through which Athenex is able to facilitate oral absorption of traditional cytotoxics, which Athenex believes may offer improved patient tolerability and
efficacy as compared to IV administration of the same cytotoxics. The Orascovery platform was developed by Hanmi Pharmaceuticals and licensed exclusively to Athenex for all major worldwide territories except Korea, which is retained by Hanmi. The
Src Kinase Inhibition platform refers to novel small molecule compounds that have multiple mechanisms of action, including the inhibition of the activity of Src Kinase and the inhibition of tubulin polymerization during cell division. Athenex
believes the combination of these mechanisms of action provides a broader range of anti-cancer activity as compared to either mechanism of action alone. Athenex’s employees worldwide are dedicated to improving the lives of cancer patients by
creating more active and tolerable treatments. Athenex has offices in Buffalo and Clarence, New York; Cranford, New Jersey; Houston, Texas; Chicago, Illinois; Hong Kong; Taipei, Taiwan and multiple locations in Chongqing, China.
