documentation of the incurrence or accrual of the costs to be reimbursed. Payment with respect to each such invoice shall be due within [...***...] after receipt by the Owing Party thereof and shall be made in accordance with Section 9.9;
provided, however, that if the Owing Party in good faith disputes any portion of any such invoice, it shall pay the undisputed portion and shall provide the Owed Party with written notice of the disputed portion and its reasons
therefor, and the Owing Party shall not be obligated to pay such disputed portion unless and until such dispute is resolved in favor of the Owed Party. The Parties shall use good faith efforts to resolve any such disputes promptly. 

9.8 Invoices and Documentation. The JFC shall approve the form of any necessary documentation relating to any payments hereunder so as
to afford the Parties appropriate accounting treatment in relation to any of the transactions or payments contemplated hereunder. All payments otherwise due and owing under this Agreement shall be supported by, and, if any such payment is due
hereunder within a specified time period, except as provided in Section 9.1, Section 9.3 and Section 9.5, such specified time period shall not start running until receipt by the owing Party of, an invoice delivered (whether
electronically or physically) to the Party owing such amount, in such form approved by the JFC. 
 9.9 Payment Method and
Currency. All payments under this Agreement shall be made by bank wire transfer in immediately available funds to an account designated by the Party to which such payments are due. All sums due under this Agreement shall be payable in
Dollars. In those cases where the amount due in Dollars is calculated based upon one or more currencies other than Dollars, such amounts shall be converted to Dollars using the average of the buying and selling exchange rate for conversion of the
applicable foreign currency into Dollars, using the average of the daily spot rates (the “Mid Price Close” found on Bloomberg (or any successor thereto), or any other source as agreed to by the Parties) over the period to which the payment
relates. 

  
 52 












 9.10 Late Payments. Unless otherwise mutually agreed by the Parties or
otherwise provided in this Agreement, all payments under this Agreement shall earn interest, to the extent permitted by applicable Law, from the date due until paid at a rate equal to one month London Inter-Bank Offering Rate (LIBOR) Dollars, as
quoted on Bloomberg (or any successor thereto) (or any other source agreed to by the Parties) effective for the date on which the payment was due, [...***...] (or the maximum allowed by applicable Law, if less) (such rate being referred
to as the “Default Interest Rate”), unless such payment amount is reasonably disputed in good faith, in which case the amount payable after such dispute is resolved shall start to earn interest hereunder on the date such dispute is
resolved. Notwithstanding the foregoing, in the event that the London Inter-Bank Offering Rate ceases to be available, the Parties shall meet and use good faith efforts to agree on an alternative reference source to establish the Default Interest
Rate; provided, however, that until the Parties reach consensus, the Default Interest Rate shall be the prime rate, as quoted on Bloomberg (or any other source agreed to by the Parties). 

9.11 Taxes. 

9.11.1 Any and all payments by or on account of any obligation of a Party under this Agreement shall be made without deduction or withholding
for any taxes, except to the extent set forth in this Section 9.11.1. If any applicable Law (as determined in the good faith discretion of an applicable Party) requires the deduction or withholding of any tax from any such payment by a Party,
then the applicable Party shall be entitled to make such deduction or withholding and shall timely pay the full amount deducted or withheld to the relevant Governmental Authority in accordance with applicable Law; provided that the
withholding Party shall furnish the other Party with proper evidence of the taxes so paid. Each Party shall cooperate with the other and furnish the other Party with appropriate documents to secure application of the most favorable rate of
withholding tax under applicable Law (or exemption from such withholding tax payments, as applicable). Without limiting the foregoing, each Party agrees to make all lawful and reasonable efforts to minimize any such taxes, assessments and fees and
will claim on the other Party’s behalf the benefit of any available treaty on the avoidance of double taxation that applies to any payments hereunder to such other Party. 

9.11.2 Notwithstanding anything to the contrary in this Agreement, all amounts due to Regeneron pursuant to this Agreement shall be
[...***...]. [...***...] shall be responsible for [...***...] (including [...***...]) applicable to the transactions contemplated by this Agreement and shall [...***...]. [...***...] shall cooperate, to the extent
reasonably required, with the [...***...]. [...***...] shall [...***...] for any [...***...] as a result of the transactions contemplated by this Agreement and if [...***...]. If [...***...] that it is required to
report any [...***...], [...***...] shall provide [...***...] and other documentation necessary or appropriate for such report. 

9.11.3 Subject to Section 20.8, if either Party assigns this Agreement to an Affiliate or Third Party and, as a result of such
assignment, any amounts payable hereunder are subject to additional withholding tax, such assigning Party shall be responsible for the resulting additional withholding taxes such that the applicable payment shall be made to the non-assigning Party without deduction for any such additional withholding; provided, however, that if the non-assigning Party derives a tax benefit (including through
the use of foreign tax credit) that is finally determined and adjudicated on a with and without basis as a result of such additional withholding, then the non-assigning Party shall promptly reimburse the
assigning Party for the amount of such benefit; provided, further, that the non-assigning Party shall take all commercially reasonable actions necessary to obtain any tax benefit (including through the
use of foreign tax credit) with respect to such additional withholding taxes and to defend such benefit in a tax audit. 

  
 53 












 9.12 Resolution of Financial Disputes. In the event there is a dispute
relating to any of the payment obligations or reports under this Article IX or [...***...] in the event that [...***...] (a “Financial Dispute”), the Party with the dispute shall provide the other Party with written
notice setting forth in reasonable detail the nature and factual basis for such good faith dispute and the Parties will seek to resolve the dispute as promptly as possible, but no later than ten (10) days after such written notice is received.
In the event that no resolution is reached by the Parties, the matter shall be submitted to the Executive Officers for a joint decision. The Executive Officers shall diligently and in good faith, attempt to resolve the referred Financial Dispute
within ten (10) Business Days of receiving such written notification. If the Executive Officers are not able to resolve the Financial Dispute within such ten (10)-Business Day period, the Financial Dispute shall be referred to the Expert Panel
in accordance with Section 10.4. Notwithstanding any other provision of this Agreement to the contrary, the obligation to pay any amount that is reasonably disputed in good faith shall not be deemed to have been triggered until such dispute is
resolved hereunder; provided that all amounts that are not reasonably disputed in good faith shall be paid in accordance with the provisions of this Agreement. 

ARTICLE X 
 DISPUTE
RESOLUTION 
 10.1 Resolution of Disputes. The Parties recognize that disputes as to certain matters may from time to time arise
that relate to either Party’s rights and obligations hereunder. It is the objective of the Parties to comply with the procedures set forth in this Agreement and to use all reasonable efforts to facilitate the resolution of such disputes in an
expedient manner by mutual agreement. 
 10.2 Resolution of Governance Disputes. Disputes, controversies and claims related to
matters intended to be decided within the governance provisions of this Agreement set forth in Article III (“Governance Disputes”) shall be resolved pursuant to Article III and, to the extent such matters constitute an Expert
Dispute, Section 10.4, except to the extent any such dispute, controversy or claim constitutes a Legal Dispute, in which event the provisions of Section 10.3 shall apply. 

10.3 Resolution of Legal Disputes. 

10.3.1 The Parties agree that, subject to Section 10.5, they shall use all reasonable efforts to resolve any Legal Dispute arising under
this Agreement by good faith negotiation. In the event that the Parties are unable to resolve any such Legal Dispute within [...***...], either Party may submit in writing the Legal Dispute to the Executive Officers for resolution, specifying
the nature of the Legal Dispute with sufficient specificity to permit adequate consideration by such Executive Officers. The Executive Officers shall meet within [...***...] of such submission and shall diligently and in good faith attempt to
resolve the referred Legal Dispute within [...***...] of such meeting. Any final decision mutually agreed to by the Executive Officers in writing shall be conclusive and binding on the Parties. 

10.3.2 In the event the Executive Officers are unable to resolve any such Legal Dispute, then, unless the Parties mutually agree to convert
such Legal Dispute to an Expert Dispute to be finally resolved through binding arbitration in accordance with Section 10.4, each Party shall be free to pursue any rights and remedies available to it at law, in equity or otherwise, subject,
however, to Section 20.1 and Section 20.14.

 10.4 Resolution of [...***...].  

10.4.1 [...***...]. 

10.4.2 [...***...]. 

10.4.3 [...***...]. 

10.4.4 [...***...]. 

10.4.5 [...***...] 

10.4.6 [...***...]. 
 10.5
Equitable Relief. The Parties hereby acknowledge and agree that the restrictions on the Parties under [...***...] are special, unique and of extraordinary character, that the Parties would not have entered into this Agreement absent the
restrictions set forth in [...***...], and that if any Party refuses or otherwise fails to act, or to cause its Affiliates or, with respect to ZLAB, its Subdistributors to act, in accordance with the provisions of [...***...], such
refusal or failure would result in irreparable injury to the other Party, the exact amount of which would be difficult to ascertain or estimate and the remedies at law for which would not be reasonable or adequate compensation. Accordingly, if any
Party refuses or otherwise fails to act, or to cause its Affiliates or, with respect to ZLAB, its Subdistributors to act, in accordance with the provisions of [...***...], then, in addition to any other remedy that may be available to any
damaged Party at law or in equity, such damaged Party will be entitled to obtain specific performance and injunctive relief, which remedy such damaged Party will be entitled to seek in any court of competent jurisdiction. Both Parties agree to waive
any requirement that the other Party (a) post a bond or other security as a condition for obtaining any such relief and (b) show irreparable harm, balancing of harms, consideration of the public interest or inadequacy of monetary damages
as a remedy. Nothing in this Article X or elsewhere in this Agreement is intended or should be construed to limit either Party’s right to equitable relief or any other remedy for a breach of any other provision of this Agreement. 

ARTICLE XI 
 TRADEMARKS
AND CORPORATE LOGOS 
 11.1 Corporate Names. Each Party and its Affiliates shall retain all right, title and interest in and to
their respective corporate names and logos. 
 11.2 Selection of Product Trademark(s). The JCC shall select one or more
Product Trademark(s) for use in the Field in the Territory. The Product in the Field shall be promoted, sold and otherwise Exploited in the Territory under the applicable Product Trademark(s) and packaging approved by the JCC. 

  
 55 












 11.3 Ownership of Product Trademark(s). ZLAB hereby acknowledges and agrees, that,
subject to the last sentence of this Section 11.3, (a) Regeneron shall have sole ownership rights in and to the Product Trademark(s) in the Territory, (b) no ownership rights are vested or created in such Product Trademark(s) in the
Territory by the licenses and other rights granted in this Article XI and (c) all use of such Product Trademark(s) by ZLAB, its Affiliates and any of its Subcontractors, including any goodwill generated in connection therewith, inures solely to
the benefit of Regeneron. ZLAB shall not, and shall cause its Affiliates and its and their Subcontractors not to, register or seek to register the Product Trademark(s) outside of the Territory. If applicable Law in any Region requires that ZLAB own
the Product Trademark(s) in such Region, then Regeneron shall provide ZLAB such assistance and cooperation as necessary or reasonably requested by ZLAB to assign ownership of such Product Trademark(s) to ZLAB in such Region and the Parties shall
enter into an agreement with respect to the prosecution, maintenance, enforcement and defense of such Product Trademark(s) for so long as they are owned by ZLAB on terms substantially similar to those provided in this Article XI when the Product
Trademark(s) are owned by Regeneron (i.e., ZLAB will have the first right to control prosecution, maintenance and enforcement of such Product Trademark(s) in such Region). 

11.4 Prosecution and Maintenance of Product Trademark(s). Subject to the last sentence of Section 11.3, Regeneron will use
Commercially Reasonable Efforts to prosecute and maintain the Product Trademark(s) in the Territory, subject to consultation and cooperation with ZLAB. ZLAB will coordinate and collaborate with Regeneron to secure and maintain all rights in and to
the Product Trademark(s) to Regeneron (taking into account applicable Law and the requirements of applicable Regulatory Authorities). Notwithstanding the foregoing, in the event Regeneron elects not to prosecute or maintain a Product Trademark in a
Region, Regeneron shall provide reasonable written notice to ZLAB of such election, and such notice shall also identify the applicable Product Trademark(s), the applicable Region to which such Product Trademark(s) pertain and the proposed
abandonment date of such Product Trademark(s) (“Trademark Abandonment Notice”); provided, however, that, unless required by applicable Law, Regeneron shall not, without ZLAB’s express written consent (which consent shall
not be unreasonably withheld, conditioned or delayed), abandon (or provide a Trademark Abandonment Notice for) any Product Trademark(s) after ZLAB has initiated launch efforts to Commercialize the Product in the Territory under such Product
Trademark(s). Within ten (10) Business Days of receipt of the Trademark Abandonment Notice by ZLAB, the JCC shall meet to discuss such Trademark Abandonment Notice and whether to pursue new or alternative Product Trademark(s) for the applicable
Region(s). If the JCC decides to pursue new or alternative Product Trademark(s) for the applicable Region(s), then the JCC shall select such Product Trademark(s) for the applicable Region(s) as promptly as reasonably possible, but in all events
within one hundred and twenty (120) days of such decision by the JCC to pursue the new or alternative Product Trademark(s). Any such mark described in a Trademark Abandonment Notice shall cease to be a Product Trademark under this Agreement as
of the date set forth in the Trademark Abandonment Notice. Each Party shall consult with such other Party in good faith, with respect to any material, substantive issue or any opposition, cancellation, invalidity or other proceeding that may be
raised or asserted against any application or registration for a Product Trademark in the Territory prior to taking any material action in response thereto. All
Out-of-Pocket Costs incurred in the filing, prosecution and maintenance of the Product Trademark(s) as provided in this Section 11.4, including clearance searches
as necessary to determine the availability of the Product Trademark(s) for use in connection with the Commercialization of, and for trademark registration for, the Product in the Territory, shall be [...***...]. 

  
 56 












 11.5 License to the Product Trademark(s). 

11.5.1 Regeneron hereby grants to ZLAB the exclusive license in the Territory to use the Product Trademark(s), with the right to grant further
sublicenses pursuant to Section 11.5.3, solely to distribute, market, promote and sell [...***...] in the Territory in accordance with the terms of this Agreement. 

11.5.2 During any period of time in which ZLAB owns the Product Trademark(s) pursuant to this Agreement, ZLAB hereby grants to Regeneron a
license to use such Product Trademark(s), with the right to grant further sublicenses through multiple tiers, for purposes of (a) Regeneron’s Development, Manufacturing and Commercialization activities with respect to the Product in the
Field in the Territory in accordance with the terms of this Agreement, which license shall be non-exclusive and (b) the Exploitation of the Product [...***...] outside the Territory, which license
shall be exclusive. 
 11.5.3 Except for any license (or, as applicable, sublicense) to a Subcontractor engaged by ZLAB in accordance with
Section 4.3 (which ZLAB shall have the right to grant in its sole discretion upon prior notice to Regeneron), ZLAB and its Affiliates and its and their Subcontractors shall not license (or, as applicable, sublicense) rights to use, or otherwise
transfer ownership of, the Product Trademark(s) without the prior written consent of Regeneron, such consent not to be unreasonably withheld, conditioned or delayed. ZLAB and its Affiliates and its and their Subcontractors shall only utilize the
Product Trademark(s) on materials related to [...***...] in the Territory (including package inserts, packaging, trade packaging, internet pages, social media, advertising and Promotional Materials used or distributed in connection with
[...***...]). Without limiting the foregoing, with respect to the use of the Product Trademark(s) owned by Regeneron, ZLAB shall, and shall cause its Affiliates and its and their Subcontractors to, adhere to and maintain the quality standards
and trademark usage guidelines as Regeneron may furnish from time to time, and Regeneron shall have the right to monitor and enforce such quality standards and trademark usage guidelines to preserve the validity and enforceability of the Product
Trademark(s). 
 11.5.4 ZLAB agrees that at no time during the Term will it or any of its Affiliates or its or their Subcontractors attempt
to use or register in the Territory any trademarks, trade dress, service marks, trade names or domain names confusingly similar to any Product Trademark in relation to a product that is not the Product, or take any other action that damages or
dilutes the rights to, or goodwill associated with, the Product Trademark(s). If requested by Regeneron, ZLAB shall (or shall cause its Affiliates and its and their Subcontractors, as appropriate, to) execute such documents as may reasonably be
required for the purpose of recording with any Governmental Authority the license, or a recordable version thereof, referred to above in this Section 11.5. Once a Product Trademark has been selected by the JCC, upon Regeneron’s request,
the Parties shall enter into a supplemental trademark license agreement in order to more fully address the Parties’ respective rights and obligations with respect to such license to such Product Trademark in a manner consistent with the
provisions set forth herein. 

  
 57 












 11.6 Use of Corporate Names. ZLAB shall not, and shall cause its Affiliates and its
and their Subcontractors not to, include Regeneron’s name on materials related to the Product in the Field in the Territory (including package inserts, packaging, trade packaging, internet pages, social media, advertising and Promotional
Materials used or distributed in connection with the Product), unless requested by Regeneron in writing or to do so would be required under applicable Law, in which case Regeneron’s name shall have equal prominence with ZLAB’s name on such
materials; provided that in the case of multi-product materials that refer to the Product in the Field as well as other (bio)pharmaceutical products, the prominence of Regeneron’s name shall be commensurate with the relative prominence
of the Product on such materials. Regeneron hereby grants to ZLAB the right, free of charge, to use its name and logo on package inserts, packaging, trade packaging, internet pages, social media and all Promotional Materials used or distributed in
connection with the Product in the Field in the Territory during the Term, in each case, only to the extent requested by Regeneron in writing or inclusion of Regeneron’s name or logo is required by applicable Law. During the Term, without
limiting Section 6.4 or Section 7.6, ZLAB shall submit samples of each such package inserts, packaging, trade packaging, etc. to Regeneron for its prior approval regarding the use of Regeneron’s name and logo, which approval shall not
be unreasonably withheld, conditioned or delayed, at least [...***...] before dissemination of such materials. Failure of Regeneron to object within such [...***...] period shall constitute approval of ZLAB’s package inserts,
packaging, trade packaging, etc.

12.1.1 Ownership of IP. Subject to Section 12.1.2 and except with respect to Product Trademark(s) as provided in Article XI, as
between the Parties, (a) each Party shall own all right, title and interest in and to any and all Information and inventions that are conceived, discovered, developed, reduced to practice (in whole or in part) or otherwise made solely by or on
behalf of such Party (or its Affiliates or its or their Sublicensees/Distributors or Subcontractors, as applicable) under or in connection with this Agreement and Patents and other intellectual property rights with respect to such Information or
inventions, and (b) the Parties shall each own an equal, undivided interest in any and all Information and inventions that are conceived, discovered, developed, reduced to practice (in whole or in part) or otherwise made jointly by or on behalf
of Regeneron (or its Affiliates or its or their Sublicensees/Distributors), on the one hand, and ZLAB (or its Affiliates or its or their Subcontractors) under or in connection with this Agreement (“Joint
Know-How”) and Patents (“Joint Patents”) and other intellectual property rights with respect to such Information or inventions. Subject to the Parties’ exclusivity obligations
under Section 2.3, (x) each Party shall have the right to Exploit, practice, enforce (subject to Section 13.1), grant licenses under and transfer its interests in the Joint IP without a duty of seeking consent or accounting to the other
Party, and the other Party hereby consents to each of the foregoing actions, (y) neither Party shall have any obligation to account to the other for profits or to obtain any approval of the other Party to license or Exploit any Joint IP by
reason of joint ownership thereof, and (z) each Party hereby waives any right it may have under the laws of any jurisdiction to require any such consent or accounting. Each Party shall cooperate in good faith with the other Party with respect
to the enforcement of Joint Patents against any alleged or threatened infringement thereof (other than Infringement, which shall be governed by Section 13.1), including by making the inventors, applicable records and documents (including
laboratory notebooks), as applicable, with respect to the Joint Patents available to the other Party and, if necessary, joining in, or being named as a necessary party to, any such enforcement action at the other Party’s request, and the costs
incurred with respect to such cooperation shall be borne by the controlling Party (and the controlling Party shall reimburse the other Party for such reasonable FTE Costs and
Out-of-Pocket Costs incurred by or on behalf of the other Party or its Affiliates in connection therewith). 

  
 58 












 12.1.2 Ownership of Product-Related IP. Subject to applicable Laws, as between the
Parties, except with respect to [...***...] as provided in [...***...], Regeneron shall own any and all: [...***...].

reduced to practice (in whole or in part) or otherwise made by a Party (or its Affiliates or its or their Sublicensees/Distributors or Subcontractors, as applicable) for the purpose of allocating proprietary rights (including Patent, copyright or
other intellectual property rights) therein, shall, for purposes of this Agreement, be made in accordance with the United States patent law and other applicable Law in the United States without regard to conflict of law, irrespective of where or
when such conception, discovery, development, reduction to practice (in whole or in part) or making occurs. ZLAB shall further ensure that any original work of authorship or artistic work created in connection with this Agreement on behalf of ZLAB,
its Affiliates or its or their Subcontractors shall be deemed a “work made for hire,” to be included among the Parties’ respective intellectual property rights as set forth in Section 12.1.1 and Section 12.1.2, as
applicable, and all rights thereto, including all copyrights and moral rights, shall upon their conception or creation exclusively, forever, irrevocably vest in or transfer to ZLAB or Regeneron as set forth in Section 12.1.1 and
Section 12.1.2, as applicable. Each Party shall, and does hereby, assign, and shall cause its Affiliates and its and their Sublicensees/Distributors and Subcontractors, as applicable, to so assign, to the other Party, without additional
compensation, such right, title and interest in and to any Information and other inventions as well as any intellectual property rights with respect thereto, as is necessary to fully effect, as applicable, (a) the sole ownership provided for in
Section 12.1.1 and Section 12.1.2 and (b) the joint ownership provided for in Section 12.1.1. Pursuant to Section 20.16, each Party shall duly execute and deliver, or cause to be duly executed and delivered, such further
instruments and do and cause to be done such further acts and things, including the filing of such applications, approvals, assignments, agreements, documents, and instruments, and shall provide any additional consents, as may be necessary or as the

activities, Pack/Label activities, Commercialization activities, or regulatory activities for ZLAB under this Agreement or who conceive, discover, develop, reduce to practice (in whole or in part) or otherwise make any Information or inventions by
or on behalf of ZLAB or its Affiliates or its or their Subcontractors under or in connection with this Agreement to be under an obligation to assign (or, if ZLAB is unable to cause such Person to agree to such assignment obligation despite
ZLAB’s using commercially reasonable efforts to negotiate such assignment obligation, provide an exclusive license under) their rights in any Information and inventions resulting therefrom to ZLAB. Without limiting the foregoing, ZLAB
acknowledges that Regeneron and its Affiliates shall not be responsible or liable for any claims for compensation by Persons who perform Development activities, Pack/Label activities, Commercialization activities, or regulatory activities for ZLAB
under this Agreement or who conceive, discover, develop, reduce to practice (in whole or in part) or otherwise make any Information or inventions by or on behalf of ZLAB or its Affiliates or its or their Subcontractors under or in connection with
this Agreement, whether such Person is named as inventor or co-inventor of any Information or invention described or covered in a Patent filed by Regeneron, its Affiliates (or its or their designee nominee) or

12.2.1 Patent Prosecution and Maintenance of Regeneron Patents and Joint Patents. [...***...]. 

12.2.2 Cooperation. For purposes of this Section 12.2, the Party prosecuting any [...***...] Patent shall be the
“Prosecuting Party.” The non-Prosecuting Party shall, and shall cause its Affiliates to, assist and cooperate with the Prosecuting Party, as the Prosecuting Party may reasonably request from
time to time, in the preparation, filing, prosecution and maintenance of the applicable [...***...] Patent and in any Adverse Proceeding with respect thereto, under this Agreement, including that the
non-Prosecuting Party shall, and shall ensure that its Affiliates, (a) offer its comments, if any, promptly, (b) provide access to relevant documents and other evidence and make its employees
available at reasonable business hours, (c) execute all such documents and instruments and perform such acts as may be reasonably necessary in order to permit the Prosecuting Party to conduct any Adverse Proceedings with respect to the
applicable Patents and (d) provide the Prosecuting Party, upon its request, with copies of any patentability search reports generated by its patent counsel with respect to the applicable Patents, including relevant Third Party patents and
patent applications; provided, however, that neither Party shall be required to provide legally privileged information with respect to such intellectual property unless and until procedures reasonably acceptable to such Party are in place to
protect such privilege. 
 12.2.3 Common Ownership Under Joint Research Agreements. Notwithstanding anything to the contrary in this
Article XII, neither Party shall have the right to make an election under 35 U.S.C. 102(c) when exercising its rights under this Article XII without the prior written consent of the other Party. With respect to any such permitted election, the
Parties shall coordinate their activities with respect to any submissions, filings or other activities in support thereof. The Parties acknowledge and agree that this Agreement is a “joint research agreement” as defined in 35 U.S.C.

the Parties, Regeneron shall have the first right to apply for patent term extensions, supplementary protection certificates and other similar extensions and protections or any other extensions that are now or become available in the future,
wherever applicable, for any Regeneron Patents and Joint Patents with respect to the Product in the Territory; provided that Regeneron shall consult with ZLAB with respect to the course of action with respect to such filings in the Territory
and consider in good faith any request from ZLAB to make such a filing in the Territory. If ZLAB requests that Regeneron apply for such an extension or protection and such request is not inconsistent with any such applications made by Regeneron and
Regeneron determines not to so apply, then ZLAB shall have the right to apply for such extension or protection at its sole cost and expense in Regeneron’s name and with Regeneron’s prior written consent, which consent shall not be
unreasonably withheld, conditioned or delayed. Each Party shall provide prompt and reasonable assistance, as requested by the other Party, to obtain such extension or supplementary protection certificate in relation to any such supplementary
protection certificate. [...***...].

Agreement)), and (b) not use Confidential Information of the disclosing Party directly or indirectly for any purpose other than performing its obligations or exercising its rights hereunder; provided that such obligations with respect to

Furthermore, any combination of individual elements of Confidential Information shall constitute Confidential Information and shall not be deemed to fall within the foregoing exclusions merely because one or more individual elements of such
combination fall within the foregoing exclusions. 
 16.1.3 Permitted Disclosure. Each Party may disclose Confidential Information of
the other Party to the extent that such disclosure is: 
 (a) made in response to a valid order of a court of competent jurisdiction or
other supra-national, federal, national, regional, state, provincial or local governmental or regulatory body of competent jurisdiction or, if in the reasonable opinion of the receiving Party’s legal counsel, such disclosure is otherwise
required by applicable Law, including by reason of filing with securities regulators; provided, however, that the receiving Party shall first have given notice to the disclosing Party and given the disclosing Party a reasonable opportunity to
quash such order or to obtain a protective order or confidential treatment requiring that the Confidential Information and documents that are the subject of such order or required to be disclosed be held in confidence by such court or agency or, if
disclosed, be used only for the purposes for which the order was issued or such disclosure was required by applicable Law; provided, further, that the Confidential Information disclosed in response to such court or governmental order or as
required by applicable Law shall be limited to that information that is legally required to be disclosed in response to such court or governmental order or by such applicable Law; 

  
 74 












 (b) made by or on behalf of the receiving Party to the Regulatory Authorities as required
in connection with any filing, application or request for Regulatory Approval pursuant to the terms of this Agreement; provided, however, that reasonable measures shall be taken to assure confidential treatment of such information to the

other Party or any of its Affiliates (or any abbreviation or adaptation thereof) in any publication, press release, marketing and promotional material, or other form of publicity without the prior written approval of such other Party in each
instance. The restrictions imposed by this Section 16.2 shall not prohibit either Party from making any disclosure identifying the other Party that is required by applicable Law. 

16.3 Publications.  

16.3.1 Regeneron shall have the exclusive right to publish or publicly disclose the results of, or information regarding, activities conducted
with respect to the Product in the Territory except that ZLAB shall have the right to publish the results of clinical trials performed pursuant to the Territory Development Plan and, to the extent such results have already been published by
Regeneron, the results of clinical trials performed pursuant to the GT Operational Plan, in each case, with the prior written approval of Regeneron in accordance with this Section 16.3. If Regeneron desires to publish or publicly disclose the
results of, or information regarding, activities conducted with respect to the Product in the Territory, ZLAB shall cooperate fully with Regeneron and shall provide such assistance as is reasonably requested by Regeneron with respect thereto,
including with respect to any application or approval necessary in the Territory. If ZLAB desires to publish the results of a clinical trial performed pursuant to the Territory Development Plan or GT Operational Plan (to the extent set forth in the
first sentence of this Section 16.3.1), ZLAB shall provide Regeneron with a draft of such proposed abstract, manuscript or summary of presentation that covers such results at least [...***...] prior to submission or disclosure, as
applicable, for Regeneron’s approval. ZLAB shall incorporate any reasonable comments of Regeneron with respect thereto. If Regeneron informs ZLAB that such proposed abstract, manuscript or summary of presentation, in Regeneron’s reasonable
judgment, could be expected to have an adverse effect on any patentable invention owned by or licensed to, in whole or in part, Regeneron, or could be expected to disclose any Information that is Confidential Information of Regeneron, ZLAB shall
delay or prevent such publication as follows: (a) with respect to a patentable invention, such publication shall be delayed sufficiently long (not to exceed [...***...]) to permit the timely preparation and filing of a patent application;
and (b) with respect to Information that is Confidential Information of Regeneron, such Information shall be deleted from the publication upon Regeneron’s request. For clarity, ZLAB shall not publish any publication or public disclosure
with respect to the Product that has not been approved by Regeneron].

16.4 Public Announcement. The Parties will mutually agree on the contents of a joint press release with respect to the execution of this
Agreement, which press release shall be issued by the Parties on or around the Effective Date. Neither Party shall issue any other public announcement, press release, or other public disclosure regarding this Agreement or its subject
matter without the other Party’s prior written consent (except, with respect to [...***...] issuance, any public announcement, press release, or other public disclosure regarding [...***...], which [...***...]), except for any
such disclosure that is, in the opinion of the disclosing Party’s counsel, required by applicable Law or the rules of a stock exchange on which the securities of the disclosing Party are listed (or to which an application for listing has been
submitted) and except that a Party may, once a press release or other public written statement is approved in writing by both Parties, make subsequent public disclosure of the information contained in such press release or other public written
statement without the further approval of the other Party. In the event a Party is, in the opinion of its counsel, required by applicable Law or the rules of a stock exchange on which its securities are listed (or to which an application for listing
has been submitted) to make such a public disclosure, such Party shall submit the proposed disclosure in writing to the other Party as far in advance as reasonably practicable (and in no event less than [...***...] prior to the anticipated
date of disclosure) so as to provide a reasonable opportunity to comment thereon. Without limiting the foregoing, the Parties acknowledge that either or both Parties may be obligated to file a copy of this Agreement with the United States Securities
and Exchange Commission or its equivalent in the Territory; provided that a Party who is so obligated shall promptly give notice to the other Party thereof and the Parties shall cooperate with each other and use reasonable efforts to obtain
confidential treatment of confidential, including trade secret, information in accordance with applicable Law. The filing Party shall provide the non-filing Party with an advance copy of this Agreement marked
to show provisions for which the filing Party intends to seek confidential treatment and shall reasonably consider the non-filing Party’s timely comments thereon and cooperate with such non-filing Party in seeking such confidential treatment and, upon the written request of the non-filing Party, shall request an appropriate extension of the term of the
confidential treatment period. For the avoidance of doubt, each Party shall be responsible for its own legal and other costs in connection with any filing governed by the terms of this Section 16.4.

 78 












 17.2.2 Control of Defense. 

(a) If the Indemnifying Party has acknowledged in writing to the Indemnified Party the Indemnifying Party’s responsibility for
indemnifying the Indemnified Party for a Third Party Claim under Section 17.1, the Indemnifying Party shall have the right to defend, at its sole cost and expense, such Third Party Claim by all appropriate proceedings, which proceedings shall
be prosecuted diligently by the Indemnifying Party to a final conclusion or settled at the discretion of the Indemnifying Party; provided that the Indemnifying Party may not enter into any compromise or settlement unless (i) such
compromise or settlement includes as an unconditional term thereof, the giving by each claimant or plaintiff to the Indemnified Party of a release from all liability in respect of such claim; and (ii) the Indemnified Party consents to such

defense of the Third Party Claim any legal counsel selected by the Indemnifying Party and approved by the Indemnified Party (which approval shall not be unreasonably conditioned, withheld or delayed). 

(b) If the Indemnifying Party has acknowledged in writing to the Indemnified Party the Indemnifying Party’s responsibility for
indemnifying the Indemnified Party for a Third Party Claim under Section 17.1 but does not does not elect to assume control of the defense of such claim or if a good faith and diligent defense is not being or ceases to be materially conducted
by the Indemnifying Party, the Indemnified Party shall have the right, at the expense of the Indemnifying Party, upon prior written notice to the Indemnifying Party of its intent to do so, to undertake the defense of such claim for the account of
the Indemnifying Party (with counsel reasonably selected by the Indemnified Party and approved by the Indemnifying Party, such approval not to be unreasonably withheld, conditioned or delayed); provided that the Indemnified Party shall keep
the Indemnifying Party apprised of all material developments with respect to such Third Party Claim and promptly provide the Indemnifying Party with copies of all correspondence and documents exchanged by the Indemnified Party and the opposing
party(ies) to such litigation. 
 (c) In the event that the Indemnifying Party does not acknowledge in writing to the Indemnified Party the
Indemnifying Party’s responsibility for indemnifying the Indemnified Party for a Third Party Claim under Section 17.1 and Indemnified Party undertakes the defense of such Third Party Claim, the Indemnified Party shall do so at its own cost
and expense, and if it is ultimately determined that the Indemnifying Party has an obligation to indemnify, defend or hold harmless the Indemnified Party from and against such Third Party Claim (or any part thereof), the Indemnifying Party shall

 79 












 (d) If the Indemnifying Party has acknowledged in writing to the Indemnified Party the
Indemnifying Party’s responsibility for indemnifying the Indemnified Party for a Third Party Claim under Section 17.1, the Indemnified Party shall not admit any liability with respect to, or settle, compromise or dispose of, such Third
Party Claim without the prior written consent of the Indemnifying Party, such consent not to be unreasonably withheld, conditioned or delayed, and the Indemnifying Party shall not be liable for any settlement or other disposition of Damages by an

bear its own costs and expenses with respect to such participation; provided that the Indemnifying Party shall bear such costs and expenses if (a) the employment thereof has been specifically authorized by the Indemnifying Party in
writing, (b) the Indemnifying Party has failed to assume the defense and employ counsel in accordance with Section 17.2.2 (in which case the Indemnified Party shall control the defense) or (c) the interests of the Indemnified Party
and any of the Indemnified Party’s indemnitees, on the one hand, and the Indemnifying Party, on the other hand, with respect to such Third Party Claim are sufficiently adverse to prohibit the representation by the same counsel of all such
Persons under applicable Law, ethical rules or equitable principles (in which case, the Indemnified Party shall control its defense). 

17.2.4 Cooperation. Regardless of whether the Indemnifying Party assumes the defense of any Third Party Claim pursuant to this
Section 17.2, the Indemnified Party shall, and shall use reasonable efforts to cause each indemnitee to, reasonably cooperate in the defense or prosecution thereof and, if the Indemnifying Party assumes the defense of any such claim, the
Indemnified Party shall, and shall use reasonable efforts to cause each indemnitee to, furnish such records, information and testimony, provide such witnesses and attend such conferences, discovery proceedings, hearings, trials and appeals, in each
case, as may be reasonably requested in connection therewith. Such cooperation shall include access upon reasonable notice during normal business hours afforded to the Indemnifying Party to, and reasonable retention by the Indemnified Party of,
records and information that are reasonably relevant to such Third Party Claim and making Indemnified Parties and other employees and agents available on a mutually convenient basis to provide additional information and explanation of any material
provided hereunder, and to the extent the Indemnified Party is entitled to indemnification pursuant to this Article XVII, the Indemnifying Party shall reimburse the Indemnified Party for all its reasonable and verifiable costs and expenses in
connection with providing such assistance.

quarantines or other public health crises, embargoes, acts of terrorism, acts of war (whether war be declared or not), insurrections, strikes, riots, civil commotions or acts of God (“Force Majeure”). Such excuse from liability and

such Force Majeure circumstances as soon as reasonably practical and will use Commercially Reasonable Efforts to mitigate the effects of such Force Majeure circumstances.

conditions of this Section 19.2, this Agreement shall be terminable by a Party in its entirety, upon written notice to the other Party, if such other Party commits a material breach under this Agreement or any Ancillary Agreement.
Such notice of termination shall set forth in reasonable detail the facts underlying or constituting the alleged breach (and specifically referencing the provisions of this Agreement or Ancillary Agreement alleged to have been breached), and
the termination that is the subject of such notice shall be effective [...***...] after the date such notice is given unless the breaching Party shall have cured such breach within such [...***...] period (or, if such material breach, by
its nature, is a curable breach but such breach is not curable within such [...***...] period, such longer period not to exceed [...***...] unless otherwise agreed by the Parties, so long as the breaching Party is using diligent efforts
to cure such breach, in which event if such breach has not been cured, such termination shall be effective on the earlier of the expiration of such [...***...] period or such time as the breaching party ceases to use diligent efforts to cure
such breach). Notwithstanding the foregoing, in the case of a breach of a payment obligation hereunder or under an Ancillary Agreement, the [...***...] period referred to in the immediately preceding sentence shall instead be [...***...]
days (and the immediately preceding parenthetical clause in the immediately preceding sentence shall not apply). Any breach of this Agreement or an Ancillary Agreement related to [...***...] shall be a material breach of this Agreement. If the
allegedly breaching Party has a bona fide good faith dispute as to the other Party’s right to terminate based on the existence, materiality or cure of the alleged breach and such disputing Party initiates good faith negotiations regarding such
dispute pursuant to Section 10.3.1 within [...***...] of first receipt of notice of termination pursuant to this Section 19.2 and, within [...***...] of first receipt of notice of termination pursuant to this Section 19.2,

enable Regeneron to seek to quash or limit such subpoena or order or to request that ZLAB do so, if applicable; and provided, further, that ZLAB provides all reasonable cooperation to assist Regeneron to quash or limit such subpoena or order
and in any event shall limit such disclosure to only that information is required by such lawfully issued subpoena or court order.

 19.4.8 Regeneron shall have the right to terminate this Agreement in its
entirety in the event that a court in the Territory, a Regulatory Authority or other Governmental Authority of competent jurisdiction in the Territory or a change in applicable Law in the Territory requires [...***...] or [...***...], or

20.9 Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the Parties hereto and their respective
successors and permitted assigns. 
 20.10 Affiliates. Regeneron may, and to the extent it is in the best interests of the Product in
the Field in the Territory shall, perform its obligations under this Agreement through one or more of its Affiliates. Notwithstanding anything to the contrary in this Agreement, ZLAB shall not have the right to perform any Development, Pack/Label or

Agreement for any sum or in any manner whatsoever, or to create or impose any contractual or other liability on the other Party without said Party’s approval. For all purposes, and notwithstanding any other provision of this Agreement to the
contrary, Regeneron’s legal relationship under this Agreement to ZLAB, and ZLAB’s legal relationship under this Agreement to Regeneron, shall be that of an independent contractor. Nothing in this Agreement shall be construed to establish a

 SCHEDULE 19.6 

Termination Arrangements 

1. The grant of rights to ZLAB provided in Section 4.1, Section 4.2 and Section 11.4 shall terminate. 

2. Each Party shall promptly collect and return, and cause its Affiliates and its and their Subcontractors to collect and return, to the other
Party or, at the other Party’s request, destroy and delete all documents (including any computer records and electronic files) containing Confidential Information (including [...***...] Information (in the case of [...***...]) and
other trade secrets) of the other Party or any of its Affiliates or its or their Subcontractors (including any archival [...***...]) and shall immediately cease, and cause its Affiliates and its and their Subcontractors to cease, all further
use of any such Confidential Information (including [...***...] Information (in the case of [...***...]) and other trade secrets); provided that [...***...] shall have the right to retain [...***...] and
[...***...]. In addition, at Regeneron’s request and option, ZLAB shall, and shall cause its Affiliates and Subcontractors to, either (a) destroy or (b) collect and transfer to Regeneron (or its designee(s)), in either case ((a)
or (b)), any remaining inventory of Promotional Materials, sales training materials and Product inventory; provided that (i) if Regeneron requests that ZLAB destroy such Product inventory, ZLAB shall, and shall cause its Affiliates and
Subcontractors to, destroy such Product inventory in accordance with Regeneron’s instructions and ZLAB shall certify such destruction to Regeneron in writing and (ii) if Regeneron requests the collection and transfer of such Product
inventory, Regeneron shall [...***...]. Notwithstanding the foregoing, each Party may retain one (1) copy of any Confidential Information ([...***...]) to the extent required by applicable Law; provided that such retained
copies will continue to be subject to the terms and conditions of this Agreement, including obligations of confidentiality and non-use/non-disclosure in accordance
herewith; provided, further, that any such Confidential Information covered by an exclusion set forth in Section 16.1.2 shall not be subject to the foregoing confidentiality and non-use/non-disclosure obligations. 
 3. Upon notice of termination of this Agreement (or during
any applicable Termination Notice Period), ZLAB shall use Commercially Reasonable Efforts to provide all cooperation and assistance to Regeneron (or its designee(s)) reasonably requested by Regeneron to enable Regeneron (or its designee(s)) to
assume with as little disruption as reasonably possible, the continued Development, Packing/Labeling and Commercialization of the Product in the Field for the Territory. Such cooperation and assistance shall be provided in a prompt and timely manner
(having regard to the nature of the cooperation or assistance requested) and shall include, if and to the extent requested by Regeneron and, except as set forth below, at Regeneron’s cost and expense (unless this Agreement is terminated by ZLAB
pursuant to [...***...] or by Regeneron pursuant to [...***...], in which case such activities shall be at ZLAB’s cost and expense for the reasonable FTE Costs and
Out-of-Pocket Costs incurred by ZLAB in connection therewith), the following: 

  
 1 












 (a) Subject to the remainder of this clause (a), ZLAB shall continue to act as the agent of
Regeneron in the preparation, submission and maintenance of any Registration Filing, Regulatory Approval or other submission or communication to a Regulatory Authority with respect to the Product in the Field in the Territory in accordance with
Article VII and shall continue to perform its obligations under Article VII until Regeneron is able to designate a replacement agent and such responsibilities are transferred to such replacement agent; provided that Regeneron shall use good
faith efforts to designate a replacement promptly. ZLAB shall transfer and assign to Regeneron (or its designee(s)) any Regulatory Documentation made, obtained or otherwise held by ZLAB or its Affiliates or any of its or their Subcontractors
relating to the Product; provided that if under applicable Law any such Regulatory Documentation is not immediately transferable in the Territory (or such transfer would materially delay the Development or Commercialization of the Product in
the Territory), ZLAB shall provide Regeneron (or its designee(s)) with all benefit of such Regulatory Documentation and such assistance and cooperation as necessary or reasonably requested by Regeneron to timely transfer such Regulatory
Documentation, as applicable, to Regeneron or its designee(s) or, at Regeneron’s option, to enable Regeneron (or its designee(s)) to obtain a substitute for such Regulatory Documentation without disruption to Regeneron’s Development,
Manufacture or Commercialization of the Product. ZLAB shall not submit any filing or have any communication with any Regulatory Authority regarding the Product without the prior written consent of Regeneron and shall make such filings and have such
communications with any Regulatory Authority regarding the Product as requested by Regeneron and for Regeneron’s (or its designee’s/designees’) benefit (to the extent not prohibited by applicable Law). In the event any Regulatory
Documentation necessary for the Development, Manufacture or Commercialization of the Product is not assigned from ZLAB to Regeneron (or its designee(s)) pursuant to this Section 3(a) of this Schedule 19.6, ZLAB hereby consents and grants
to Regeneron (or its designee(s)) the exclusive (even as to ZLAB and its Affiliates) right to access and reference through multiple tiers (without any further action required on the part of ZLAB, whose authorization to file this consent with any
Regulatory Authority is hereby granted) any such item. 
 (b) with respect to any clinical trials or other Development activities with
respect to the Product that Regeneron determines should be terminated, unless the continued conduct of such clinical trial or other Development activity is required by the applicable Regulatory Authority or applicable Law or the termination of such
clinical trial or other Development activity would be inconsistent with standards of ethical conduct of human clinical trials, ZLAB shall wind-down such activities in a smooth, orderly and efficient manner in compliance with applicable Law and with
due regard for patient safety and the rights of any subjects that are participants in any such clinical trials, and take any actions that Regeneron deems reasonably necessary or appropriate to avoid any human health or safety problems or that is
otherwise required by applicable Law. 
 (c) subject to Section 3(b) of this Schedule 19.6, unless expressly prohibited by any
Regulatory Authority, at Regeneron’s written request, transition and transfer control to Regeneron (or its designee(s)) of all clinical trials being conducted under this Agreement by or on behalf of ZLAB with respect to the Product as of the
effective date of termination and continue to conduct such clinical trials for up to six (6) months to enable such transfer to be completed without interruption of any such clinical trial unless such transfer is expressly prohibited by the
applicable Regulatory Authority or applicable Law or would be inconsistent with standards of ethical conduct of human clinical trials, in which case ZLAB shall continue to conduct such clinical trial to completion at Regeneron’s direction;
provided that Regeneron shall use Commercially Reasonable Efforts to assume control of such clinical trial but, for clarity, Regeneron shall not have any obligation to continue to conduct any clinical trial unless (i) required by the
applicable Regulatory Authority or applicable Law or (ii) ceasing to conduct such clinical trial would be inconsistent with standards of ethical conduct of human clinical trials. 

  
 2 












 (d) To the extent ZLAB owns the Product Trademark(s) in accordance with Section 11.3,
ZLAB shall assign and transfer to Regeneron (or its designee(s)) ZLAB’s entire right, title and interest in and to the Product Trademark(s) (including, for clarity, any accompanying logos, slogans, trade names, domain names, trade dress or
other indicia of origin) for the Product and Promotional Materials (including any copyrights thereto) relating to the Product; provided that nothing herein is intended to convey any rights in or to ZLAB’s corporate name and logos or any
trade names except for the limited rights set forth herein. 
 (e) ZLAB shall provide to Regeneron (or its designee(s)) [...***...]
consistent with ZLAB’s regular business practices, to the extent [...***...], including [...***...], or [...***...]. 

(f) To the extent fully assignable to Regeneron (or its designee), ZLAB shall assign to Regeneron (or its designee(s)) any applicable
Subcontractor agreements that are specific and solely attributable to the Product and other material service provider contracts that are specific and solely attributable to significant services to be performed by Third Parties to the extent related
to the Development, Packing/Labeling or Commercialization of the Product in the Field for the Territory, as reasonably requested by Regeneron. With respect to any Subcontractor agreements or other material service provider contracts that
(i) otherwise relate to the Product, but are not specific and solely attributable to the Product or (ii) are specific and solely attributable to the Product but are not fully assignable to Regeneron (or its designee), ZLAB shall use
Commercially Reasonable Efforts to partially assign to Regeneron (or its designee(s)) such agreement with respect to the Product or, if such partial assignment is not possible, ZLAB shall use Commercially Reasonable Efforts to obtain for Regeneron
(or its designee(s)) substantially all of the practical benefit and burden under such agreement to the extent applicable to the Product, including by (A) entering into appropriate and reasonable alternative arrangements on terms agreeable to
Regeneron and (B) subject to the consent and control of Regeneron, enforcing, at Regeneron’s cost and expense and for the account of Regeneron, any and all rights of ZLAB, or its Affiliate or its or their Subcontractor, as applicable,
against the other party thereto arising out of the breach or cancellation thereof by such other party or otherwise. 
 4. Without limitation
of the generality of the foregoing, the Parties shall use Commercially Reasonable Efforts to complete the transition of the Development, Packing/Labeling and Commercialization of the Product in the Field in the Territory hereunder to Regeneron (or
its designee(s)) as soon as is reasonably possible. 
 5. For the avoidance of doubt, except as expressly provided in this Agreement,
Regeneron shall not be required to provide ZLAB any consideration in exchange for the transition of the Product pursuant to the provisions of this Schedule 19.6. 

6. Without limitation of any of the foregoing in this Schedule 19.6, ZLAB shall duly execute and deliver, or cause to be duly executed
and delivered, such instruments and shall do and cause to be done such acts and things, including the filing of such assignments, agreements, documents, and instruments, as may be necessary under, or as Regeneron may reasonably request in connection
