 (b)
rebates actually paid to individual or group purchasers of the Product that are solely on account of the purchase of such Product; 
 (c)
credits issued for the Product recalled or not accepted by customers or other refunds, allowances and chargebacks actually granted and related to the Product; 

(d) (i) freight expense (actual), including insurance, to the extent it is not charged to or reimbursed by the customer, (ii) early
payment discounts, (iii) bad debt written off under GAAP, with reasonable collection efforts and added back if collected; and

but excluding income taxes) actually incurred, paid or collected and remitted to the relevant tax authority for the sale of the Product; provided that any amount of such taxes refunded, recovered or credited back by the relevant tax authority
shall be included in Net Sales. 
 Each of the amounts set forth above shall be determined from the books and records of Zai, its Affiliate or Sublicensee,
maintained in accordance with GAAP or in the case of Sublicensees, such similar accounting principles, consistently applied, and any amounts that are deducted from Net Sales pursuant to one subsection may not be deducted pursuant to another
subsection (i.e., a deduction may only be taken once). 
 The transfer of a Product to an Affiliate, Sublicensee, or other Third Party (i) in
connection with the Development or testing of a Product (including the conduct of clinical studies), (ii) for purposes of distribution as promotional samples, (iii) for indigent or similar public support or compassionate use programs, or
(iv) by and between Zai and its Affiliates or Sublicensees shall not, in any case, be considered a Net Sale of a Product under this Agreement. Subject to the foregoing, any sales income received by Zai, its Affiliates or Sublicensees for
Products prior to or after Regulatory Approval shall be Net Sales and subject to the Royalty Payments under Section 9.4(a). 
 Net Sales shall also
include and be deemed to have been made with respect to any Products used by Zai or any Affiliate, for its own commercial purposes, or transferred to any Third Party for less than what the transferee is then charging in normal arms-length sales
transactions; and Net Sales in all such cases shall be deemed to have been made at the prices therefor at which such Products are then being sold to the customers of such user or transferor (or of Zai, if an Affiliate is a user but not a seller) in
arms-length sales transactions. For clarity, in the event the Product is sold in an arms-length transaction to a governmental agency, a group purchase entity or any other entity having the bargaining power to negotiate the purchase price below
normal retail price in transactions of lesser volume, Net Sales shall be calculated based on the actual price negotiated and agreed to for such agency or entity and not be based on the price charged in other arms-length sales transactions. 

To the extent that Zai or any of its Affiliates, or Sublicensees, provides to the purchasing Third Party discounts or allowances that are applicable to
purchases of the Product and one or more other products (such as in a “bundled sale” arrangement), such discounts and allowances shall be allocated between the Product (for purposes of the deductions used in calculating Net Sales as above)
and such other products in an equitable and commercially reasonable manner that does not unfairly or inappropriately bias the level of discounting against the Product (as compared to the other products). 

If Zai or any of its Affiliates, or Sublicensees, sells a Product as a Licensed Component of a Combination Product in the Territory in any Calendar Quarter,
then Net Sales shall be calculated by multiplying the Net Sales of the Combination Product during such Calendar Quarter by the fraction A/(A+B), where A is the average Net Sales per unit sold of the Licensed Component when sold separately in the
Territory during such Calendar Year (calculated by determining the Net Sales of the Licensed Component during such Calendar Quarter in accordance with the definition of Net Sales set forth herein and dividing such Net Sales by the number of units of
the Licensed Component during such Calendar Quarter) and B is the average Net Sales per unit sold of the Other Component(s) included in the Combination Product when sold separately during such Calendar Quarter (calculated by determining the Net
Sales of such Other Component(s) sold during such Calendar Quarter by applying the definition of Net Sales set forth herein as if it applied to sales of such Other Component(s) and dividing such Net Sales by the number of units of such Other
Component(s) sold during such Calendar Quarter). In each case, A and B shall be adjusted on a pro rata basis to account for dosing differences between the amounts of Licensed Component and Other Component(s) included in the Combination Product
relative to the amounts of Licensed Component and Other Component(s) included in the separately sold product. 
 For purposes of calculating the average Net
Sales per unit sold of a Licensed Component and Other Component(s) of a Combination Product, any of the deductions described herein that apply to such Combination Product shall be allocated among sales of the Licensed Component and sales of the
Other Component(s) included in such Combination Product as follows: (1) deductions that are attributable solely to the Licensed Component or one of the Other Component(s) shall be allocated solely to Net Sales of the Licensed Component or such
Other Component, as applicable, and (2) all other deductions shall be allocated among sales of the Licensed Component and sales of the Other Component(s) in proportion to Zai’s and TPTX’s mutual agreement of the fair market value of
the Licensed Component and the Other Component(s).

 In the event that no separate sales of the Licensed Component or any Other Component(s) included in a
Combination Product are made by Zai or its Affiliates, or Sublicensees, during a Calendar Quarter in which such Combination Product is sold, the average Net Sales per unit sold in the above described equation shall be replaced with Zai’s and
TPTX’s mutual written agreement of the fair market value of the Licensed Component and each of the Other Component(s) included in such Combination Product.

Commercialization activities, including assistance pursuant to Sections 8.1 and 8.4 as requested by Zai.

(i) unless otherwise agreed by the Parties in writing, establish or maintain any branch, warehouse or distribution facility for Products in such countries (except, in the event such Party is Zai, Zai shall have the right to maintain one or more
warehouses outside the Territory solely to support the packaging and labelling activities of the Products by Zai or its Affiliates outside the Territory and, in the event such Party is TPTX, TPTX shall have the right to maintain one or more
warehouses in the Territory solely to support the Retained Rights), (ii) engage in any advertising or promotional activities relating to Products that are directed primarily to customers or other purchaser or users of Products located in such

 8.7. TPTX Acquirer’s Right of First
Negotiation. Zai hereby grants to TPTX for the benefit of the Third Party that is the acquirer of TPTX in a Change of Control of TPTX (the “TPTX Acquirer”) a right of first negotiation to
co-Commercialize the Products in the Territory (the “TPTX Acquirer ROFN”) in accordance with this Section 8.7. Following a Change of Control of TPTX, TPTX Acquirer may provide written
notice to Zai of its interest in negotiating an agreement with Zai to co-Commercialize the Products in the Territory (the “TPTX Acquirer ROFN Exercise Notice”). If TPTX Acquirer
delivers such TPTX Acquirer ROFN Exercise Notice, TPTX Acquirer shall have the exclusive right to negotiate with Zai for a period up to [...***...] days from the date of the TPTX Acquirer ROFN Exercise Notice (or any additional period of time
if mutually agreed in writing by TPTX Acquirer and Zai) (the “TPTX Acquirer ROFN Negotiation Period”) the terms and conditions of such agreement to co-Commercialize the Products
in the Territory. If the TPTX Acquirer ROFN Exercise Notice has not been received by Zai on or prior to the date Zai files the first Regulatory Approval Application for the first Product in the Territory, the TPTX Acquirer ROFN shall automatically
expire upon such date, and Zai shall thereafter be free to enter into an agreement with a Third Party for the co-Commercialization of any and all Products in the Territory. If TPTX Acquirer provides Zai with a
TPTX Acquirer ROFN Exercise Notice prior to the expiration of the TPTX Acquirer ROFN and Zai and TPTX Acquirer fail to enter into a definitive agreement regarding the terms and conditions with respect to such co-Commercialization of Products in the
Territory prior to the expiration of the TPTX Acquirer ROFN Negotiation Period, (i) the TPTX Acquirer ROFN shall automatically expire on the last day of the TPTX Acquirer ROFN Negotiation Period and (ii) Zai shall be free to enter into an
agreement with a Third Party for the co-Commercialization of any and all Products in the Territory. 
 8.8. Medical Affairs.
Zai shall be solely responsible, at its sole cost and expense, for conducting medical affairs activities with respect to the Products in the Territory, including communications with key opinion leaders, medical education, symposia, advisory boards
(to the extent related to medical affairs or clinical guidance), publications, congress presentations and posters, published manuscripts, activities performed in connection with patient registries and post-approval trials, and other medical programs
and communications, including educational grants, research grants (including conducting investigator-initiated studies), and charitable donations to the extent related to medical affairs and not to other activities that do not involve the promotion,
marketing, sale, or other Commercialization of the Products, all of which shall be conducted in accordance with Applicable Law. Zai shall update the JSC at each regularly scheduled JSC meeting regarding Zai’s medical affairs activities. Each
such update shall be in a form to be agreed by the JSC and shall summarize Zai’s, its Affiliates’ and Sublicensees’ significant Commercialization activities with respect to the Products in the Territory, covering subject matter at a
level of detail reasonably required by TPTX and sufficient to enable TPTX to determine Zai’s compliance with its diligence obligations pursuant to Section 8.1. In addition, Zai shall make available to TPTX such additional information about
its Commercialization activities as may be reasonably requested by TPTX from time to time. All updates and reports generated pursuant to this Section 8.3 shall be the Confidential Information of Zai.

accounting firm’s written report so concluding. If such accounting firm concludes that an overpayment was made, then such overpayment shall be credited against any future payment due to TPTX hereunder (if there is no future payment due, then
TPTX shall promptly refund such overpayment to Zai). TPTX shall bear the full cost of such audit unless such audit discloses that the additional payment payable by Zai for the audited period is more than [...***...] of the amount otherwise

(d) Zai shall include in each relevant sublicense granted by it a provision requiring any Sublicensee to maintain records of sales of Products
made pursuant to such sublicense, and to grant access to such records by an accounting firm to the same extent and under the same obligations as required of Zai under this Agreement. TPTX shall advise Zai in advance of each audit of any such
Sublicensee with respect to the Net Sales of the Products either by TPTX or its designated auditor under the terms of such Sublicensee agreement. TPTX shall provide Zai with a summary of the results received from the audit and, if Zai so requests, a
copy of the audit report. TPTX shall pay the full costs charged by the accounting firm, unless the audit discloses that the additional payments payable to TPTX for the audited period is more than [...***...] from the amounts otherwise paid for
that audited period, in which case Zai shall pay the reasonable fees and expenses charged by the accounting firm. 
 9.7.
Interest. Each Party shall pay interest on any amounts overdue under this Agreement [...***...] from the day payment was initially due; provided, however, that in no case shall such interest rate exceed the highest rate

 9.8. Taxes. 

(a) Withholding VAT Taxes. [...***...] any deduction for any VAT that Zai may be required by Applicable Laws in the Territory to

upon receipt of a valid VAT invoice (where such invoice is required under local VAT laws). If Zai is required to deduct or withhold any VAT on any payments payable by Zai under this Agreement (the “Withholding VAT Taxes”), Zai will
(i) pay such Withholding VAT Tax on behalf of TPTX to the appropriate Governmental Authority, (ii) furnish TPTX with proof of payment of such Withholding VAT Tax within [...***...] Business Days following such payment., and
(iii) [...***...]. Zai will promptly provide to TPTX applicable receipts evidencing payment of such Withholding VAT Taxes and other documentation reasonably requested by TPTX. Upon Zai’s request, TPTX shall provide reasonable
assistance to Zai for Zai to recover any such Withholding VAT Taxes. For clarity, [...***...].

[...***...] Business Days following such payment; and (C) deduct such Withholding Income Taxes from the payment payable to TPTX. Zai will promptly provide to TPTX applicable receipts evidencing payment of such Withholding Incomes Taxes
and other documentation reasonably requested by TPTX. Upon TPTX’s request, Zai shall provide reasonable assistance to TPTX for TPTX to recover any such Withholding Income Taxes. For clarity, in the event that TPTX actually recovers any such
Withholding Income Taxes from the applicable Governmental Authority to which such Taxes were paid, such recovered Withholding Income Taxes shall be retained by TPTX with no obligation to Zai. 

(c) Cooperation. Zai shall inform TPTX in writing of any prescribed forms that are necessary to claim a reduced rate or exemption from
any Withholding Taxes and if TPTX is entitled under any applicable Tax treaty to a reduction of rate of, or the elimination of, applicable Withholding Tax, TPTX shall use Commercially Reasonable Efforts to deliver to Zai or the appropriate
Governmental Authority (with the assistance of Zai to the extent that this is reasonably required) the prescribed forms necessary to reduce the applicable rate of withholding or to relieve Zai of its obligation to withhold such Withholding Taxes,
and Zai shall apply the reduced rate of withholding if so permitted by Applicable Laws.

 (d) Assignment. If TPTX assigns, transfers or otherwise disposes of some or all of
its rights and obligations under this Agreement to any Person and if, as a result of such action, the Withholding Taxes required by Applicable Laws with respect to payments under this Agreement is increased, then any amount payable to TPTX’s
assignee or transferee under this Agreement shall be limited to the amount that would have been payable to TPTX had no such assignment, transfer or disposal occurred. If Zai assigns, transfers or otherwise disposes of some or all of its rights and
obligations under this Agreement to any Person and if, as a result of such action, the Withholding Income Taxes required by Applicable Laws with respect to payments under this Agreement is increased, then any amount payable by Zai’s assignee or
transferee under this Agreement shall be increased to ensure that TPTX receives the amount that would have been payable to TPTX had no such assignment, transfer or disposal occurred and it shall be a condition precedent to any such assignment,
transfer or disposal that such assignee or transferee shall assume Zai’s withholding and payment obligations as set forth in this Section 9.8. 

9.9. Blocked Currency. If by Applicable Laws in a region in the Territory, conversion into Dollars or transfer of funds
of a convertible currency to the United States becomes materially restricted, forbidden or substantially delayed, then Zai shall promptly notify TPTX and, thereafter, amounts accrued in such country or region under this ARTICLE 9 shall be paid to
TPTX (or its designee) in such country or region in local currency by deposit to an escrow account in a local bank designated by TPTX and to the credit of TPTX, unless the Parties otherwise agree.

Information of the other Party (the “Disclosing Party”) shall keep confidential and not publish, make available or otherwise disclose any Confidential Information to any Third Party, without the express prior written consent of the
Disclosing Party; provided, however, the Receiving Party may disclose the Confidential Information to those of its Affiliates, officers, directors, employees, agents, consultants or independent contractors (including licensees and
sublicensees) of such Receiving Party who need to know the Confidential Information in connection with exercising rights or performing obligations as contemplated by this Agreement or any other written agreement between the Parties and are bound by
confidentiality and non-use obligations with respect to such Confidential Information consistent with those set forth herein; the Receiving Party shall remain responsible for the compliance by its Affiliates,
officers, directors, employees, agents, consultants or independent contractors (including licensees and sublicensees) with such confidentiality and non-use obligations. The Receiving Party shall exercise at a
minimum the same degree of care it would exercise to protect its own Confidential Information (and in no event less than a reasonable standard of care) to keep confidential the Confidential Information. The Receiving Party shall use the Confidential
Information solely in connection with exercising rights or performing obligations as contemplated by this Agreement or any other written agreement between the Parties. 

(b) It shall not be considered a breach of this Agreement if the Receiving Party discloses Confidential Information or either Party discloses
the terms and conditions of this Agreement in order to comply with a lawfully issued court or governmental order or with a requirement of Applicable Laws or the rules of any internationally recognized stock exchange; provided that: (i) the
Receiving Party gives prompt written notice of such disclosure requirement to the Disclosing Party and cooperates with the Disclosing Party’s efforts to oppose such disclosure or obtain a protective order for such Confidential Information, and
(ii) if such disclosure requirement is not quashed or a protective order is not obtained, the Receiving Party shall only disclose those portions of the Confidential Information that it is legally required to disclose and shall make a reasonable
effort to obtain confidential treatment for the disclosed Confidential Information. To the extent there is any conflict between this ARTICLE 10 and any other agreement related to Confidential Information entered into between the Parties, including
the Confidentiality Agreement, the terms of this ARTICLE 10 shall control to the extent of such conflict.

Product Development work in order to obtain recognition within the scientific community and to advance the state of scientific knowledge, and the need to protect Confidential Information, intellectual property rights and other business interests of
the Parties. Subject to the immediately preceding sentence, Zai shall provide TPTX with the opportunity to review and comment on any proposed publication that pertains to the Products at least [...***...] days prior to its intended submission
for publication which shall only be permitted in the Territory and as to data, results and the like with respect to patients or subjects located in the Territory. TPTX shall provide Zai with its comments, if any, within [...***...] days after
the receipt of such proposed publication. Zai shall consider in good faith the comments provided by TPTX and shall comply with TPTX’s request to: (a) remove any and all Confidential Information of TPTX from such proposed publication; and
(b) delay the submission for a period up to [...***...] days as may be reasonably necessary to seek patent protection for the information disclosed in the proposed publication. Zai agrees to acknowledge the contribution of TPTX and

 10.2. Publicity; Use of Names. 

(a) Subject to permitted disclosures under Section 10.1(b) or under Section 10.2(c), each of the Parties agrees not to disclose to

regulations. Notwithstanding the foregoing, the Parties agree upon the initial press release(s) to announce the execution of this Agreement as contained in Schedule 10.2(a); thereafter, TPTX and Zai may each disclose to Third Parties the information
contained in such press release(s) or in any other press releases or disclosures made in accordance with this Section 10.2, without the need for further approval by the other. 

(b) The Parties acknowledge the importance of supporting each other’s efforts to publicly disclose results and significant developments
regarding a Product for use in the Field in the Territory and other activities in connection with this Agreement, beyond what may be strictly required by Applicable Laws and the rules of a recognized stock exchange, and each Party may make such
disclosures from time to time with respect to a Product in the case of TPTX, with prior notice to Zai, and in the case of Zai, with the prior written approval of TPTX, which approval shall not be unreasonably withheld, conditioned or delayed. Such
disclosures may include achievement of significant events in the Development (including regulatory process) or Commercialization of a Product for use in the Field in the Territory. Unless otherwise requested by the applicable Party, Zai shall
indicate that TPTX is the licensor of a Product and Licensed Technology in each public disclosure issued by Zai regarding a Product. When Zai elects to make any public disclosure under this Section 10.2(b) or TPTX elects to make any public
disclosure regarding results and significant developments regarding a Product for use in the Field in the Territory under this Section 10.2(b), the disclosing Party shall give the other Party reasonable notice to review and comment on such
statement, and, in the case of proposed disclosures by Zai, (i) if TPTX does not notify Zai in writing within [...***...] days or such shorter period if required by Applicable Laws of any reasonable objections, as contemplated in this
Section 10.2(b), such disclosure shall be deemed approved, and (ii) if TPTX does notify Zai in writing within the time period set forth in clause (i) above, and reasonably determines that such public disclosure would entail the public
disclosure of TPTX’s Confidential Information or of patentable Inventions upon which patent applications should be filed prior to such public disclosure, such public disclosure shall be delayed for such period as may be reasonably necessary for
deleting any such Confidential Information of TPTX, or the drafting and filing of a patent application covering such Inventions; provided that such additional period shall not exceed [...***...] days from the proposed date of the public
disclosure, and, in any event, TPTX shall work diligently and reasonably to agree on the text of any proposed disclosure in an expeditious manner. The principles to be observed in such disclosures shall be accuracy, compliance with Applicable Laws
and regulatory guidance documents, and reasonable sensitivity to potential negative reactions of applicable Regulatory Authorities.

Party’s business under this Agreement, including as required by Applicable Laws or the rules of a recognized stock exchange. To the extent a Party is publicly listed or becomes publicly listed, and subject to Section 10.2(b) as applicable,
such Party may issue press releases or make disclosures to the SEC or other applicable agency as it determines, based on advice of counsel, as reasonably necessary to comply with laws or regulations or for appropriate market disclosure;
provided that each Party shall provide the other Party with advance notice of legally required disclosures to the extent practicable. The Parties shall consult with each other on the provisions of this Agreement to be redacted in any filings

(a) As between the Parties, (i) TPTX shall remain the sole and exclusive owner of all Licensed Technology and (ii) Zai shall remain
the sole and exclusive owner of all Zai IP. 
 (b) Ownership of all Inventions (other than any Invention that is an Improvement) shall be
allocated based on inventorship, as determined in accordance with the rules of inventorship under the United States patent laws. All Improvements, whether invented, discovered, generated or made solely by either Party, its Affiliates, or its or its
Affiliates’ employees, agents or independent contractors or jointly by both Parties, their Affiliates, or their or their Affiliates’ employees, agents or independent contractors, shall be the sole property of TPTX and shall be included in
the Licensed Technology (if within the scope of such definition) and included in the licenses and rights granted to Zai. A Party shall own all Inventions (in the case of Zai, other than Improvements) that are invented, discovered, generated or made
solely by it, its Affiliates, or its or its Affiliates’ employees, agents or independent contractors (“Sole Inventions”), and (i) TPTX’s Sole Inventions shall be included in the Licensed Technology (if within
the scope of such definition) and included in the licenses and rights granted to Zai by TPTX hereunder; and (ii) Zai’s Sole Inventions (which are not Improvements) shall be included in the Zai IP (if within the scope of such definition)
and included in the licenses and rights granted to TPTX by Zai hereunder. The Parties shall jointly own all Inventions (other than Improvements) that are made jointly by a Party, its Affiliate, or its or its Affiliate’s employees, agents or
independent contractors together with the other Party, its Affiliates, or its or its Affiliate’s employees, agents or independent contractors (“Joint Inventions”). Patents claiming the Joint Inventions shall be referred

license of the Joint Inventions or Joint Patents (subject to the licenses granted to the other Party under this Agreement). 
 (c) Zai shall
and hereby does assign to TPTX all right, title and interest in and to all Improvements. Zai shall take (and cause its Affiliates, Sublicensees and their employees, agents, and contractors to take) such further actions reasonably requested by TPTX
to effectuate such assignment and to assist TPTX in obtaining Patent and other intellectual property rights protection for the Improvements. Zai shall obligate its Affiliates, Sublicensees and contractors to assign all Improvements to Zai (or
directly to TPTX) so that Zai can comply with its obligations under this Section 13.1(c), and Zai shall promptly obtain such assignment.

 13.3. Patent Prosecution. 

(a) Licensed Patents and Joint Patents in the Territory. TPTX shall have the first right, but not the obligation, to conduct Patent
Prosecution and maintenance of (i) the Licensed Patents in the Territory and (ii) Joint Patents in the Territory, at its sole cost. TPTX shall consult with Zai and keep Zai reasonably informed of the Patent Prosecution or maintenance of
the Licensed Patents and Joint Patents in the Territory and shall provide Zai with all material correspondence received from any patent authority in the Territory in connection therewith. In addition, TPTX shall provide Zai with drafts of all
proposed material filings and correspondence to any patent authority in the Territory in connection with the Patent Prosecution or maintenance of the Licensed Patents or Joint Patents for Zai’s review and comment prior to the submission of such
proposed filings and correspondence. TPTX shall consider in good faith Zai’s comments on such Patent Prosecution or maintenance but shall have final decision-making authority under this Section 13.3(a). Further, TPTX shall notify Zai of
any decision to cease Patent Prosecution or maintenance of any Licensed Patent or Joint Patent in the Territory at least [...***...] days before any due date for filing, payment or other action to avoid loss of rights, in which case Zai shall
have the right to continue the Patent Prosecution or maintenance of such Licensed Patent or Joint Patent in the Territory at Zai’s discretion and expense. If Zai decides to take over Patent Prosecution or maintenance of a Licensed Patent or
Joint Patent in such region(s) in the Territory, then TPTX shall promptly deliver to Zai copies of all necessary files related to such Licensed Patent or Joint Patent in such region(s) in the Territory and shall take all actions and execute all
documents reasonably necessary for Zai to assume such responsibility. For the avoidance of doubt, Zai’s assumption of responsibility for Patent Prosecution or maintenance of any Licensed Patent or Joint Patent in any region(s) in the Territory
pursuant to this Section 13.3(a) shall not change the Parties’ respective ownership rights with respect to such Licensed Patent or Joint Patent. 

(b) Zai Patents. Zai shall, at its sole cost and expense, have the sole right, but not the obligation, in the Territory and the first
right, but not the obligation, outside the Territory, to conduct the Patent Prosecution and maintenance of any Patents within the Zai IP (the “Zai Patent”). Zai shall keep TPTX reasonably informed of the status of all actions
taken, and shall consider in good faith TPTX’s recommendations with respect to the Zai Patents prosecuted by Zai worldwide. Further, Zai shall notify TPTX of any decision to cease Patent Prosecution or maintenance of any Zai Patent outside the
Territory at least [...***...] days before any due date for filing, payment or other action to avoid loss of rights, in which case TPTX shall have the right to continue the Patent Prosecution or maintenance of such Zai Patent outside the
Territory at TPTX’s discretion and expense. If TPTX decides to take over Patent Prosecution or maintenance of a Zai Patent outside the Territory, then Zai shall promptly deliver to TPTX copies of all necessary files related to such Zai Patent
outside the Territory and shall take all actions and execute all documents reasonably necessary for TPTX to assume such responsibility. For the avoidance of doubt, TPTX’s assumption of responsibility for Patent Prosecution or maintenance of any
Zai Patent outside the Territory pursuant to this Section 13.3(b) shall not change the Parties’ respective ownership rights with respect to such Licensed Patent or Joint Patent. 

(c) Joint Patents Outside the Territory. TPTX shall have the sole decision-making authority, at its sole cost and expense, over the
Patent Prosecution and maintenance of Joint Patents outside the Territory.

Third Party of any of the Licensed Patents (including any Joint Patents in the Territory), which infringement adversely affects or is expected to adversely affect any Product in the Field in the Territory, and any related declaratory judgment,
opposition, or similar action by a Third Party alleging the invalidity, unenforceability or non-infringement of any of the Licensed Patents (including any Joint Patents in the Territory) in the Territory

such Product Infringement in the Territory at its own expense as it reasonably determines appropriate. If Zai does not bring such legal action prior to the earlier of: (i) [...***...] days following Zai’s receipt or delivery of the notice
under Section 13.4(a), or (ii) [...***...] days before the deadline, if any, set forth in the Applicable Laws for the filing of such actions, or discontinues the prosecution of any such action after filing without abating such
infringement, TPTX shall have the right to bring and control any legal action in connection with such Product Infringement at its own expense as it reasonably determines appropriate. 

(c) TPTX shall have the exclusive right, but not the obligation, to bring and control any legal action in connection with any alleged or
threatened infringement by a Third Party of any of the Licensed Patents (other than Joint Patents) that is not a Product Infringement, and any related declaratory judgment, opposition, or similar action by a Third Party alleging the invalidity,
unenforceability or non-infringement of any of the Licensed Patents (other than Joint Patents), at its own expense as it reasonably determines appropriate. 

(d) Zai shall have the first right, but not the obligation, to enforce the Joint Patents in the Territory for any infringement that is not a
Product Infringement at its own expense as it reasonably determines appropriate. TPTX shall have the first right, but not the obligation, to enforce the Joint Patents outside the Territory for any infringement at its own expense as it reasonably
determines appropriate. If the Party with the first right of enforcement in respect of Joint Patents under this Section 13.4(d) decides not to bring such legal action in any jurisdiction(s) subject to its first right, it shall so inform the
other Party promptly and the other Party shall have the right, but not the obligation, to bring and control any legal action in connection with such infringement in such jurisdiction(s) at its own expense as it reasonably determines appropriate.

 (e) TPTX shall have the first right to bring and control any legal action in connection with any alleged or threatened infringement by a

action by a Third Party alleging the invalidity, unenforceability or non-infringement of any of the Zai Patents (other than Joint Patents) outside the Territory, at its own expense as it reasonably determines
appropriate. If TPTX does not bring such legal action prior to the earlier of: (i) [...***...] days following receipt or delivery of notice between the Parties regarding such alleged infringement, or (ii) [...***...] days before the
deadline, if any, set forth in the Applicable Laws for the filing of such actions, or discontinues the prosecution of any such action after filing without abating such infringement, Zai shall have the right to bring and control any legal action in
connection with infringement at its own expense as it reasonably determines appropriate. Except as otherwise provided in this Section 13.4(e), Zai shall have the exclusive right, but not the obligation, to bring and control any legal action in
connection with any alleged or threatened infringement by a Third Party of any of the Zai Patents (other than Joint Patents), and any related declaratory judgment, opposition, or similar action by a Third Party alleging the invalidity,
unenforceability or non-infringement of any of the Zai Patents (other than Joint Patents), at its own expense as it reasonably determines appropriate. 

(f) At the request of the Party bringing an action related to Product Infringement or otherwise as described in this Section 13.4, the
other Party shall provide reasonable assistance in connection therewith, including by executing reasonably appropriate documents, cooperating in discovery and joining as a party to the action if required by Applicable Laws to pursue such action, at
each such Party’s sole cost and expense. In connection with an action related to Product Infringement or otherwise as described in this Section 13.4, the Party bringing the action shall not enter into any settlement admitting the
invalidity or non-infringement of, or otherwise impairing the other Party’s rights in the Licensed Patents, Zai Patents or Joint Patents, as applicable, without the prior written consent of the other
Party. The enforcing Party shall keep the non-enforcing Party reasonably informed of the status of any action it brought in connection with such Product Infringement or otherwise as described in this

 (a) Each
Party shall notify the other in writing of any allegations it receives from a Third Party that the Development, Manufacture, use, Commercialization or other exploitation of any Licensed Compound or Product or any embodiment of any technology or
intellectual property licensed by a Party under this Agreement infringes the intellectual property rights of such Third Party. Such notice shall be provided promptly, but in no event after more than [...***...] days following receipt of such
allegations. Such written notice shall include a copy of any summons or complaint (or the equivalent thereof) received regarding the foregoing. Each Party shall assert and not waive the joint defense privilege with respect to all communications
between the Parties. 
 (b) As between the Parties, Zai shall have the first right, but not the obligation to control and be solely
responsible for the defense of any such suit against Zai, at Zai’s sole cost and expense; provided, however, Zai shall not enter into any compromise or settlement relating to such suit that (i) admits the invalidity or
unenforceability of any Licensed Patents or Joint Patents; or (ii) requires abandonment of any Licensed Patents or Joint Patents; or (iii) contemplates payment or other action by TPTX or has a material adverse effect on TPTX’s
business, in all cases ((i) through (iii)), without obtaining the prior written consent of TPTX.

legal action subject to its first right, it shall so inform TPTX promptly and TPTX shall have the right to bring and control any such legal action in connection with such infringement in the Territory at its own expense as it reasonably determines
appropriate; provided, however, TPTX shall not enter into any compromise or settlement relating to such suit that (i) admits the invalidity or unenforceability of any Licensed Patents or Joint Patents; or (ii) requires
abandonment of any Licensed Patents or Joint Patents; or (iii) contemplates payment or other action by Zai or has a material adverse effect on Zai’s business, in all cases ((i) through (iii)), without obtaining the prior written consent of
Zai.

non-defending Party does not join such suit, the defending Party shall keep the non-defending Party reasonably informed of the status of such suit. The non-defending Party shall be entitled to attend any substantive meetings, hearings, or other proceedings related to such suit. The defending Party shall provide the
non-defending Party with copies of all pleadings and other documents to be filed with the court reasonably in advance and shall consider in good faith reasonable and timely input from the non-defending Party during the course of the suit.

upon request of TPTX, any agreements or arrangements with Third Party to Develop and Commercialize the Products in the Territory. To the extent that any such contract between Zai and a Third Party is not assignable to TPTX or its designee, then Zai
shall reasonably cooperate with TPTX to arrange to continue to and provide such services from such entity. 
 (v) Ongoing
Clinical Trial. If at the time of such termination, any Clinical Trials for the Products are being conducted by or on behalf of Zai, then, at TPTX’s election on a Clinical Trial-by-Clinical Trial basis: (1) Zai shall, and shall cause its Affiliates and Sublicensees to, (A) continue to conduct such Clinical Trial during the Transition Period or another period of time
as determined by TPTX after the effective date of such termination at TPTX’s cost, and (B) after such period, to (y) fully cooperate with TPTX to transfer the conduct of all such Clinical Trial to TPTX or its designee or

for such Clinical Trial after the effective date of such termination, and (2) Zai shall, and shall cause its Affiliates and Sublicensees to, [...***...], orderly wind down the conduct of any such Clinical Trial which is not assumed by
TPTX under clause (1). 
 (vi) Inventory. At TPTX’s election and request, Zai shall (1) transfer to TPTX or its designee
all inventory of the Product [...***...] then in possession or control of Zai, its Affiliates or Sublicensees; provided that TPTX shall pay Zai a price equal to Zai’s costs for such Products or (2) (A) continue to use Commercially
Reasonable Efforts to Commercialize all inventory of the Products then in possession or control of Zai during the Transition Period and make the corresponding payments, including any milestone payments or royalties to TPTX under this Agreement as
though this Agreement had not been terminated and (B) after the Transition Period, transfer to TPTX or its designee any remaining inventory of the Product to TPTX or its designee at a price equal to Zai’s costs for such Products. 

(vii) Return of Confidential Information. At the Disclosing Party’s election, the Receiving Party shall
return (at Disclosing Party’s expense) or destroy all tangible materials comprising, bearing, or containing any Confidential Information of the Disclosing Party relating to the Product that are in the Receiving Party’s or its
Affiliates’ or Sublicensees’ possession or control and provide written certification of such destruction (except to the extent any information is the Confidential Information of both Parties or to the extent that the Receiving Party has
the continuing right to use the Confidential Information under this Agreement); provided that the Receiving Party may retain one copy of such Confidential Information for its legal archives. Notwithstanding anything to the contrary set forth

 DISPUTE
RESOLUTION 
 15.1. General. The Parties recognize that a claim, dispute or controversy may arise relating to this
Agreement or to the breach, enforcement, interpretation or validity of this Agreement (a “Dispute”). Any Dispute, including Disputes that may involve the Affiliates of any Party, shall be resolved in accordance with this ARTICLE 15.

 15.2. Continuance of Rights and Obligations during Pendency of
Dispute Resolution. If there are any Disputes in connection with this Agreement, including Disputes related to termination of this Agreement under ARTICLE 14, all rights and obligations of the Parties shall continue until such time as
any Dispute has been resolved in accordance with the provisions of this ARTICLE 15.

 15.4. Arbitration.

 (a) If the Parties fail to resolve the Dispute through escalation to the Executive Officers under Section 15.3, and a Party desires
to pursue resolution of the Dispute, the Dispute shall be submitted by either Party for final resolution by arbitration under the Rules of Arbitration of the International Chamber of Commerce (“ICC Rules”), excepted as
modified herein. Any disputes concerning the propriety of the commencement of the arbitration or the scope or applicability of this agreement to arbitrate shall be finally settled by the arbitral tribunal. The arbitration shall be conducted by a

 52 

 (b) The Parties agree that any award or decision made by the arbitral tribunal shall be
final and binding upon them and may be enforced in the same manner as a judgment or order of a court of competent jurisdiction, and the Parties undertake to carry out any award without delay. The arbitral tribunal shall render its final award or
decision within nine (9) months from the date on which the request for arbitration by one of the Parties wishing to have recourse to arbitration is received by the ICC Secretariat. The arbitral tribunal shall resolve the Dispute by applying the
provisions of this Agreement and the governing law set forth in Section 16.5. 
 (c) By agreeing to arbitration, the Parties do not
intend to deprive any court of its jurisdiction to issue, at the request of a Party, a pre-arbitral injunction, pre-arbitral attachment or other order to avoid
irreparable harm, maintain the status quo, preserve the subject matter of the Dispute, or aid the arbitration proceedings and the enforcement of any award. Without prejudice to such provisional or interim remedies in aid of arbitration as may be
available under the jurisdiction of a competent court, the arbitral tribunal shall have full authority to grant provisional or interim remedies and to award damages for the failure of any Party to the dispute to respect the arbitral tribunal’s
order to that effect. 
 (d) EACH PARTY HERETO WAIVES: (I) ITS RIGHT TO TRIAL OF ANY ISSUE BY JURY, AND (II) ANY CLAIM FOR
ATTORNEY FEES, COSTS AND PREJUDGMENT INTEREST.

authorized to (i) award non-economic damages, (ii) award punitive damages or any other damages expressly excluded under this Agreement, or (iii) reform, modify or materially change this
Agreement or any other agreements contemplated hereunder; provided, however, that the damage limitations described in clauses (i) and (ii) will not apply if such damages are statutorily imposed. Each
Party shall bear its own attorney’s fees, costs, and disbursements arising out of the arbitration, and shall pay an equal share of the fees and costs of the administrator and the arbitrators; provided, however, that the
arbitrators shall be authorized to determine whether a Party is the prevailing party, and if so, to award to that prevailing party reimbursement for any or all of its reasonable attorneys’ fees, costs and disbursements (including, for example,
expert witness fees and expenses, photocopy charges, travel expenses, etc.), or the fees and costs of the administrator and the arbitrators. 

(f) Notwithstanding anything in this Section 15.4, in the event of a Dispute with respect to (i) the validity, scope, enforceability
or ownership of any Patent or other intellectual property rights, (ii) a matter for which this Agreement assigns decision-making to the Parties or to the JSC or requires the consent of one or both of the Parties, (iii) the necessity of
obtaining a Third Party license by Zai in the Territory in accordance with Section 9.4(c)(iii), or (iv) any antitrust, anti-monopoly or competition law or regulation, whether or not statutory, and such Dispute is not resolved in accordance
with Section 15.3, such Dispute shall not be submitted to an arbitration proceeding in accordance with this Section 15.4, unless otherwise agreed by the Parties in writing, and instead, either Party may initiate litigation in a court of
competent jurisdiction in any country in which such rights apply. 
 ARTICLE 16 

MISCELLANEOUS 

16.1. Force Majeure. Neither Party shall be held liable to the other Party nor be deemed to have defaulted under or
breached this Agreement for failure or delay in performing any obligation under this Agreement to the extent such failure or delay is caused by or results from causes beyond the reasonable control of the affected Party including embargoes, war, acts
of war (whether war be declared or not), insurrections, riots, civil commotions, strikes, lockouts or other labor disturbances, fire, floods, pandemics, epidemics or other acts of God or any other deity (or orders of any Governmental Authority

successor to substantially all of the business of such Party to which this Agreement relates (whether by merger, sale of stock, sale of assets, exclusive license or other transaction), and (b) either Party may assign this Agreement to an
Affiliate without the other Party’s prior written consent for so long as such Affiliate remains an Affiliate of the Party making the assignment. For clarity, each Party may discharge any obligations and exercise any right hereunder through any
of its Affiliates and each Party hereby guarantees the performance by its Affiliates of such Party’s obligations under this Agreement, and shall cause its Affiliates to comply with the provisions of this Agreement in connection with such
performance. This Agreement shall inure to the benefit of and be binding on the Parties’ successors and permitted assignees. Any assignment or transfer in violation of this Section 16.2 shall be null and void and wholly invalid, the
assignee or transferee in any such assignment or transfer shall acquire no rights whatsoever, and the non-assigning non-transferring Party shall not recognize, nor shall
it be required to recognize, such assignment or transfer. 
 16.3. Severability. If any one or more of the provisions
contained in this Agreement is 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. The Parties shall in such an instance use their best efforts to replace the invalid, illegal or unenforceable provision(s) with valid, legal and enforceable
provision(s) which, insofar as practical, implement the purposes of this Agreement.

discovered or created during the Term, to Exploit the Products in the Field in the Territory. For clarity, it is understood that the foregoing license does not include the right to modify the Licensed Compound and Zai agrees that it shall not, and
shall require that its Affiliates and Sublicensees do not, modify the Licensed Compound, except in each case by making pharmaceutically acceptable salts, hydrates and solvates thereof, formulations of any of the foregoing or as expressly authorized
in advance by Cullinan in writing.

provided that Zai shall have the right to cure, if curable, such breach on behalf of such Sublicensee within forty (40) days following the receipt of notice of such breach. 

  
 13 

 (b) Restrictions. Zai shall not grant a sublicense to any Third Party that has been
debarred or disqualified by any Governmental Authority or is subject to any proceedings, sanctions or fines under any Anti-Corruption Law. Zai shall ensure, prior to engaging any Third Party as a Sublicensee that such Third Party is subject to
written agreements containing terms and conditions that: (i) require each such Sublicensee to protect and keep confidential any Confidential Information of the Parties, including in accordance with ARTICLE 10; (ii) provide Cullinan with the
right to audit (either by itself or through Zai or Zai’s designee) the books and records of each such Sublicensee in accordance with this Agreement (including pursuant to Sections 5.7(a), 6.10, 8.6, 9.6(b), 9.6(d), and 11.5(a)(iv)); (iii) do
not impose any payment obligations or liability on Cullinan; and (iv) are otherwise consistent with the terms of this Agreement. Zai shall provide a copy of the complete executed agreement with each Sublicensee to Cullinan; provided that

of its obligations under this Agreement that have been delegated or sublicensed to any Sublicensee, and Cullinan shall have the right to proceed directly against Zai without any obligation to first proceed against such Sublicensee. Cullinan may
require that Zai enforce any provisions of any agreement between Zai and a Sublicensee against the applicable Sublicensee.

licenses granted to it under this Agreement. 
 2.6. Existing Cullinan
In-License. All licenses and other rights granted to Zai under this Agreement (including any sublicense rights) are subject to the rights and obligations of Cullinan under the Taiho Agreement. Zai
acknowledges and agrees that [***], as amended from time to time in accordance with Section 11.2(i) and 11.2(j), (as if sublicensees were expressly named in each such provision, to the extent sublicensees are not so named therein).

that is being Exploited in the Territory (collectively, “Competing Activities”), being performed by the Acquirer or its Affiliates at the closing of the applicable transaction, or (2) any Competing Activities undertaken
after the closing of the Change of Control transaction by an Acquirer or its Affiliates, in each case of (1) and (2) as long as (A) no Licensed Technology or Zai IP (as applicable) or Confidential Information of the other Party (if

(a) If, during the Term, Cullinan enters into any agreement with a Third Party pursuant to which it obtains a licensable or sublicensable (in
accordance with the terms of this Agreement) right or license from such Third Party to any Patents or Know-How that would, but for the provisions of this Section 2.9 constitute Licensed Technology, then

Cullinan shall provide Zai with a copy of the Global Development Plan within thirty (30) days of the Effective Date, which identifies (i) the first Pivotal Study and (ii) such other Global Studies that include clinical sites for
Clinical Trials in the Territory (such other Global Studies, excluding the first Pivotal Study, the “Existing Global Studies”). If Cullinan amends the Global Development Plan after the Effective Date, which amendment adds Global
Studies to include any clinical sites for Clinical Trials in the Territory beyond the Existing Global Studies, Cullinan shall present to the JSC any such additional Global Study for Zai’s potential participation in such Global Study and provide
the JSC with a study schematic and rationale for the study prior to initiation of such study for the JSC’s review (which such review, for the avoidance of doubt, shall not be required to take place at an official meeting of the JSC);
provided, however, that notwithstanding to the contrary herein (including Section 3.2(f)), any amendment to the Global Development Plan to the extent relating to the first Pivotal Study, any Existing Global Study or Joint Global
Study that would materially change Zai’s obligations in the Territory shall be mutually agreed on by the Parties. 

  
 19 

 (b) Zai (i) shall, at its sole cost and expense, participate in the first Pivotal Study

enrolling the percentage of the subjects for such Existing Global Studies as specified in the Global Development Plan existing as of the Effective Date, and (iii) may, in its sole discretion, agree to participate in such other Global Study
presented by Cullinan (each of the Existing Global Studies and any such agreed future Global Studies, a “Joint Global Study”). Within thirty (30) days of the Effective Date, Cullinan shall provide Zai with a list
of the Joint Global Studies as of such date. Zai shall be responsible for all activities (if any) associated with conducting each Joint Global Study in the Territory set forth in the Global Development Plan existing as of the Effective Date and each
additional Joint Global Study as outlined in the plan for such Joint Global Study as mutually agreed by the Parties and any additional Joint Global Study so agreed between the Parties shall be included in an amendment to the Global Development Plan.
Zai shall use Commercially Reasonable Efforts to recruit, enroll, treat, and provide follow-up in a timely manner a certain number or percentage (as applicable) of the total number of patients to be treated
under the protocol set forth in the Regulatory Submission to the FDA and NMPA (or such increased or decreased number of patients as may be required by a Regulatory Authority inside the Territory) for the Joint Global Study and in accordance with the
Global Development Plan, which percentage shall be up to [***] of the total number of subjects for such Joint Global Study; provided that, if the number of subjects for any Joint Global Study that Zai plans to enroll from clinical trial sites
in the Territory would exceed [***] of the total number subjects for such Joint Global Study based on the Global Development Plan, [***]. For the first Pivotal Study, following the Effective Date, Cullinan will transition clinical study sites in the
Territory to Zai pursuant to an agreed transition plan as contemplated by the Development Plan, and Zai will bear the costs of such study in the Territory after the Effective Date, provided that, only to the extent that subjects are enrolled
in such study by Cullinan prior to the Effective Date, Cullinan will reimburse Zai for the costs incurred by or on behalf of Zai for such subjects enrolled in such study prior to the Effective Date on a Calendar Quarterly basis in accordance with a
detailed budget for such costs agreed in advance by the Parties. 
 (c) Zai, itself or with or through any other of its Affiliates or
Sublicensees, shall, in accordance with Section 6.1, be the Authorized Regulatory Agent of each Joint Global Study in the Territory. For any Joint Global Study, Zai shall be responsible for all costs incurred by or on behalf of Zai in the
performance of such Joint Global Study in the Territory (except to the extent of assistance provided by Cullinan without additional charge in accordance with Section 4.2), and Cullinan shall be responsible for all other costs incurred for or in
connection with such Joint Global Study. 

  
 20 

 (d) If Zai elects not to participate in any Global Study presented by Cullinan (other than
the first Pivotal Study and the Existing Global Studies in which Zai is participating) by notifying Cullinan in writing of such election not to participate (or by failing to notify Cullinan in writing of its election to participate) within thirty

(a) Zai shall keep, and shall require its Affiliates and Sublicensees to keep (all in accordance with the GAAP), for a period not less than
[***] years from the end of the Calendar Year to which they pertain, complete and accurate records in sufficient detail to properly reflect Net Sales and to enable any Milestone Payment payable hereunder to be determined. 

(b) Upon the written request of Cullinan, Zai shall permit, and shall cause its Affiliates and Sublicensees to permit, an independent
certified public accounting firm of nationally recognized standing selected by Cullinan and reasonably acceptable to Zai, at Cullinan’s expense, to have access during normal business hours to such records of Zai or its Affiliates as may be
reasonably necessary to verify the accuracy of the payments hereunder for any Calendar Year ending not more than [***] years prior to the date of such request. These rights with respect to any Calendar Year shall terminate [***] years after the end
of any such Calendar Year and shall be limited to once each Calendar Year (provided that the foregoing frequency limit shall not apply if Cullinan has reasonable cause). Cullinan shall provide Zai with a copy of the accounting firm’s

to Zai such accounting firm’s written report so concluding. If such accounting firm concludes that an overpayment was made, then such overpayment shall be credited against any future payment due to Cullinan hereunder (if there is no future
payment due, then Cullinan shall promptly refund such overpayment to Zai). Cullinan shall bear the full cost of such audit unless such audit discloses that the additional payment payable by Zai for the audited period is more than five percent (5%)

granted by it a provision requiring any Sublicensee to maintain records of sales of Products made pursuant to such sublicense, and to grant access to such records by an accounting firm to the same extent and under the same obligations as required of
Zai under this Agreement. Cullinan shall advise Zai in advance of each audit of any such Sublicensee with respect to the Net Sales of the Products either by Cullinan or its designated auditor under the terms of such Sublicensee agreement. Cullinan
shall provide Zai with a summary of the results received from the audit and, if Zai so requests, a copy of the audit report. Cullinan shall pay the full costs charged by the accounting firm, unless the audit discloses that the additional payments
payable to Cullinan for the audited period is more than five percent (5%) from the amounts otherwise paid for that audited period, in which case Zai shall pay the reasonable fees and expenses charged by the accounting firm.

(5%) points above the Prime Rate assessed from the day payment was initially due; provided, however, that in no case shall such interest rate exceed the highest rate permitted by Applicable Laws. The payment of such interest shall not

 ARTICLE 10 

CONFIDENTIALITY; PUBLICATION 

10.1. Nondisclosure Obligation. 

(a) For the Term and five (5) years thereafter, the Party receiving (the “Receiving Party”) the Confidential
Information of the other Party (the “Disclosing Party”) shall keep confidential and not publish, make available or otherwise disclose any Confidential Information to any Third Party, without the express prior written consent of the
Disclosing Party; provided, however, the Receiving Party may disclose the Confidential Information to those of its Affiliates, officers, directors, employees, agents, consultants or independent contractors (including licensees and
sublicensees) of such Receiving Party who need to know the Confidential Information in connection with exercising rights or performing obligations as contemplated by this Agreement or any other written agreement between the Parties and are bound by
confidentiality and non-use obligations with respect to such Confidential Information consistent with those set forth herein; the Receiving Party shall remain responsible for the compliance by its Affiliates,
officers, directors, employees, agents, consultants or independent contractors (including licensees and sublicensees) with such confidentiality and non-use obligations. Either Party may disclose the terms and
existence of this Agreement to any bona fide existing or potential investors, lenders and acquirers and the accountants and advisors of any of the foregoing who are bound by a written agreement (or in the case of attorneys or other professional
advisors, formal ethical duties) requiring such recipients to treat, hold and maintain the terms of this Agreement as Information in a manner that is consistent with the terms and conditions of this Agreement. The Receiving Party shall exercise at a
minimum the same degree of care it would exercise to protect its own Confidential Information (and in no event less than a reasonable standard of care) to keep confidential the Confidential Information. The Receiving Party shall use the Confidential
Information solely in connection with exercising rights or performing obligations as contemplated by this Agreement or any other written agreement between the Parties. 

(b) It shall not be considered a breach of this Agreement if the Receiving Party discloses Confidential Information or either Party discloses
the terms and conditions of this Agreement in order to comply with a lawfully issued court or governmental order or with a requirement of Applicable Laws or the rules of any internationally recognized stock exchange; provided that:
(i) the Receiving Party gives prompt written notice of such disclosure requirement to the Disclosing Party and cooperates with the Disclosing Party’s efforts to oppose such disclosure or obtain a protective order for such Confidential
Information, and (ii) if such disclosure requirement is not quashed or a protective order is not obtained, the Receiving Party shall only disclose those portions of the Confidential Information that it is legally required to disclose and shall
make a reasonable effort to obtain confidential treatment for the disclosed Confidential Information. To the extent there is any conflict between this ARTICLE 10 and any other agreement related to Confidential Information entered into between the
Parties, including the Confidentiality Agreement, the terms of this ARTICLE 10 shall control to the extent of such conflict. 
 (c)
Scientific Publication. The JSC shall discuss the publication strategy for the publication of scientific papers, abstracts, meeting presentations and other disclosure of the results of the Clinical Trials carried out under this
Agreement, taking into consideration the Parties’ interest in publishing the results of the Product Development work in order to obtain recognition within the scientific community and to advance the state of scientific knowledge, and the need
to protect Confidential Information, intellectual property rights and other business interests of the Parties; provided that Zai’s publication outside the Territory (including in any form or media that may be distributed outside the Territory)
shall require Cullinan’s prior written consent, not to be unreasonably withheld. Subject to the immediately preceding sentence, Zai shall provide Cullinan with the opportunity to review and comment on any proposed publication that pertains to
the Products at least forty-five (45) days prior to its intended submission for publication which shall only be permitted in the Territory and as to data, results and the like with respect to patients or subjects located in the Territory.
Cullinan shall provide Zai with its comments, if any, within thirty (30) days after the receipt of such proposed publication. Zai shall consider in good faith the comments provided by Cullinan and shall comply with Cullinan’s request to:
(a) remove any and all Confidential Information of Cullinan from such proposed publication; and (b) delay the submission for a period up to ninety (90) days as may be reasonably necessary to seek patent protection for the information
disclosed in the proposed publication. Zai agrees to acknowledge the contribution of Cullinan and Cullinan’s employees in all publication as scientifically appropriate. Zai shall have no right to publish outside the Territory (including in any
form or media that may be distributed outside the Territory) without Cullinan’s prior written consent. 

  
 34 

 10.2. Publication and Listing of Clinical Trials. With respect to the
listing of Clinical Trials or the publication of Clinical Trial results for the Products and to the extent applicable to a Party’s activities conducted under this Agreement, each Party shall comply with (a) the Pharmaceutical Research and
Manufacturers of America (PhRMA) Guidelines on the listing of Clinical Trials and the Publication of Clinical Trial results, and (b) any Applicable Law or applicable court order, stipulations, consent agreements, and settlements entered into by
such Party. The Parties agree that any such listings or publications made pursuant to this Section 10.2 shall be considered a publication for purposes of this Agreement and shall be subject to Section 10.1. 

10.3. Publicity; Use of Names. 

(a) Subject to permitted disclosures under Section 10.1(b) or under Section 10.2(c), each of the Parties agrees not to disclose to
any Third Party the terms and conditions of this Agreement without the prior approval of the other Party, except to (i) advisors (including consultants, financial advisors, attorneys and accountants), (ii) bona fide potential and existing
investors, acquirers, merger partners or other financial or commercial partners on a need to know basis for the sole purpose of evaluating an actual or potential investment, acquisition or other business relationship, in each case under
circumstances that reasonably protect the confidentiality thereof, (iii) to the extent necessary to comply with the terms of agreements with Third Parties, or (iv) to the extent required by Applicable Laws, including securities laws and
regulations. Notwithstanding the foregoing, the Parties agree upon the initial press release(s) to announce the execution of this Agreement as contained in Schedule 10.3(a); thereafter, Cullinan and Zai may each disclose to Third Parties the
information contained in such press release(s) or in any other press releases or disclosures made in accordance with this Section 10.3, without the need for further approval by the other. 

(b) The Parties acknowledge the importance of supporting each other’s efforts to publicly disclose results and significant developments
regarding a Product for use in the Field in the Territory and other activities in connection with this Agreement, beyond what may be strictly required by Applicable Laws and the rules of a recognized stock exchange, and each Party may make such
disclosures from time to time with respect to a Product in each case with the prior written approval of the other Party, which approval shall not be unreasonably withheld, conditioned or delayed. Such disclosures may include achievement of
significant events in the Development (including regulatory process) or Commercialization of a Product for use in the Field in the Territory. Unless otherwise requested by the applicable Party, Zai shall indicate that Cullinan is the licensor of a
Product and Licensed Technology in each public disclosure issued by Zai regarding a Product. When Zai elects to make any public disclosure under this Section 10.3(b) or Cullinan elects to make any public disclosure regarding results and
significant developments regarding a Product for use in the Field in the Territory under this Section 10.3(b), the disclosing Party shall give the other Party reasonable notice to review and comment on such statement, it being understood that
(i) if the other Party does not notify such Party in writing within thirty (30) days or such shorter period if required by Applicable Laws of any reasonable objections, as contemplated in this Section 10.3(b), such disclosure shall be
deemed approved, and (ii) if the other Party does notify such Party in writing within the time period set forth in clause (i) above, and reasonably determines that such public disclosure would entail the public disclosure of the other
Party’s Confidential Information or of patentable Inventions upon which patent applications should be filed prior to such public disclosure, such public disclosure shall be delayed for such period as may be reasonably necessary for deleting any
such Confidential Information of the other Party, or the drafting and filing of a patent application covering such Inventions; provided that such additional period shall not exceed ninety (90) days from the proposed date of the public
disclosure, and, in any event, the other Party shall work diligently and reasonably to agree on the text of any proposed disclosure in an expeditious manner. The principles to be observed in such disclosures shall be accuracy, compliance with
Applicable Laws and regulatory guidance documents, and reasonable sensitivity to potential negative reactions of applicable Regulatory Authorities. 

  
 35 

 (c) The Parties acknowledge the need to keep investors and others informed regarding such
Party’s business under this Agreement, including as required by Applicable Laws or the rules of a recognized stock exchange. To the extent a Party is publicly listed or becomes publicly listed, and subject to Section 10.3(b) as applicable,
such Party may issue press releases or make disclosures to the SEC or other applicable agency as it determines, based on advice of counsel, as reasonably necessary to comply with laws or regulations or for appropriate market disclosure;
provided that each Party shall provide the other Party with advance notice of legally required disclosures to the extent practicable. The Parties shall consult with each other on the provisions of this Agreement to be redacted in any filings
made by a Party with the SEC or as otherwise required by Applicable Laws; provided that each Party shall have the right to make any such filing as it reasonably determines necessary under Applicable Laws. 

10.4. Prior Confidentiality Agreement.

remain the sole and exclusive owner of all Zai IP. 
 (b) As between the Parties, ownership of all Inventions (other than any Invention that
is an Improvement) shall be allocated based on inventorship, as determined in accordance with the rules of inventorship under the United States patent laws. All Improvements, whether invented, discovered, generated or made solely by either Party,
its Affiliates, or its or its Affiliates’ employees, agents or independent contractors or jointly by both Parties, their Affiliates, or their or their Affiliates’ employees, agents or independent contractors, shall be the sole property of
Cullinan and shall be included in the Licensed Technology, and included in the licenses and rights granted to Zai. A Party shall own all Inventions (in the case of Zai, other than Improvements) that are invented, discovered, generated or made solely
by it, its Affiliates, or its or its Affiliates’ employees, agents or independent contractors (“Sole Inventions”), and (i) Cullinan’s Sole Inventions shall be included in the Licensed Technology (if within the
scope of such definition) and included in the licenses and rights granted to Zai by Cullinan hereunder; and (ii) Zai’s Sole Inventions (which are not Improvements) shall be included in the Zai IP (if within the scope of such definition)
and included in the licenses and rights granted to Cullinan by Zai hereunder. The Parties shall jointly own all Inventions (other than Improvements) that are made jointly by a Party, its Affiliate, or its or its Affiliate’s employees, agents or
independent contractors together with the other Party, its Affiliates, or its or its Affiliate’s employees, agents or independent contractors (“Joint Inventions”). Patents claiming the Joint Inventions shall be referred
to as “Joint Patents.” Each Party shall own an undivided equal interest in the Joint Inventions and Joint Patents, without a duty of accounting or an obligation to seek consent from the other Party for the exploitation or
license of the Joint Inventions or Joint Patents (subject to the licenses granted to the other Party under this Agreement). 

  
 41 

 (c) As between the Parties, Cullinan shall own all Improvements and Zai shall and hereby
does assign to Cullinan all right, title and interest in and to all Improvements. Zai shall take (and cause its Affiliates, Sublicensees and their employees, agents, and contractors to take) such further actions reasonably requested by Cullinan to
effectuate such assignment and to assist Cullinan in obtaining Patent and other intellectual property rights protection for the Improvements. Zai shall obligate its Affiliates, Sublicensees and contractors to assign all Improvements to Zai (or
directly to Cullinan) so that Zai can comply with its obligations under this Section 13.1(c), and Zai shall promptly obtain such assignment. 

13.2. Disclosure of Inventions. Each Party shall promptly disclose to the other Party all Inventions arising from
the Parties’ activities under this Agreement, including all invention disclosure or other similar documents submitted to such Party by its or its Affiliates’ employees, agents, or independent contractors relating to such Inventions, and
shall also promptly respond to reasonable requests from the other Party for additional information relating to such Inventions. 

13.3. Patent Prosecution. 

(a) Licensed Patents in the Territory. Cullinan shall have the first right, but not the obligation, to conduct Patent Prosecution and
maintenance of (i) the Licensed Patents in the Territory and (ii) Joint Patents in the Territory [***]. Cullinan shall consult with Zai and keep Zai reasonably informed of the Patent Prosecution or maintenance of the Licensed Patents and
Joint Patents in the Territory and shall provide Zai with all material correspondence received from any patent authority in the Territory in connection therewith. In addition, Cullinan shall provide Zai with drafts of all proposed material filings
and correspondence to any patent authority in the Territory in connection with the Patent Prosecution or maintenance of the Licensed Patents or Joint Patents for Zai’s review and comment prior to the submission of such proposed filings and
correspondence. Cullinan shall consider in good faith Zai’s comments on such Patent Prosecution or maintenance but shall have final decision-making authority under this Section 13.3(a). Further, Cullinan shall notify Zai of any decision to
cease Patent Prosecution or maintenance of any Licensed Patent or Joint Patents in the Territory at least thirty (30) days before any due date for filing, payment or other action to avoid loss of rights, in which case Zai shall have the right
to continue the Patent Prosecution or maintenance of such Licensed Patent or Joint Patents in the Territory at Zai’s discretion and expense. If Zai decides to take over Patent Prosecution or maintenance of a Licensed Patent or Joint Patents in
such Region(s) in the Territory, then Cullinan shall promptly deliver to Zai copies of all necessary files related to such Licensed Patent or Joint Patents in such Region(s) in the Territory and shall take all actions and execute all documents
reasonably necessary for Zai to assume such responsibility. For the avoidance of doubt, Zai’s assumption of responsibility for Patent Prosecution or maintenance of any Licensed Patent or Joint Patents in any Region(s) in the Territory pursuant
to this Section 13.3(a) shall not change the Parties’ respective ownership rights with respect to such Licensed Patent or Joint Patents. 

(b) Zai Patents. Zai shall, at its sole cost and expense, have the sole right, but not the obligation, in the Territory and the first
right, but not the obligation, outside the Territory, to conduct the Patent Prosecution and maintenance of any Patents within the Zai IP (the “Zai Patent”). Zai shall keep Cullinan reasonably informed of the status of all
actions taken, and shall consider in good faith Cullinan’s recommendations with respect to the Zai Patents prosecuted by Zai worldwide. Further, Zai shall notify Cullinan of any decision to cease Patent Prosecution or maintenance of any Zai
Patent outside the Territory at least thirty (30) days before any due date for filing, payment or other action to avoid loss of rights, in which case Cullinan shall have the right to continue the Patent Prosecution or maintenance of such Zai
Patent outside the Territory at Cullinan’s discretion and expense. If Cullinan decides to take over Patent Prosecution or maintenance of a Zai Patent outside the Territory, then Zai shall promptly deliver to Cullinan copies of all necessary
files related to such Zai Patent outside the Territory and shall take all actions and execute all documents reasonably necessary for Cullinan to assume such responsibility. For the avoidance of doubt, Cullinan’s assumption of responsibility for
Patent Prosecution or maintenance of any Zai Patent outside the Territory pursuant to this Section 13.3(b) shall not change the Parties’ respective ownership rights with respect to such Licensed Patent or Joint Patent.

threatened infringement by a Third Party of any of the Licensed Patents (including any Joint Patents in the Territory), which infringement adversely affects or is expected to adversely affect any Product in the Field in the Territory, and any
related declaratory judgment, opposition, or similar action by a Third Party alleging the invalidity, unenforceability or non-infringement of any of the Licensed Patents (including any Joint Patents in the
Territory) within the scope of the license grant in Section 2.1 (collectively “Product Infringement”). 
 (b)
Cullinan shall have the first right to bring and control any legal action in connection with such Product Infringement in the Territory at its own expense as it reasonably determines appropriate. If Cullinan does not bring such legal action prior to
the earlier of: (i) ninety (90) days following Cullinan’s receipt or delivery of the notice under Section 13.4(a), or (ii) thirty (30) days before the deadline, if any, set forth in the Applicable Laws for the filing of such
actions, or discontinues the prosecution of any such action after filing without abating such infringement, Zai shall have the right to bring and control any legal action in connection with such Product Infringement at its own expense as it
reasonably determines appropriate. 
 (c) Cullinan shall have the exclusive right, but not the obligation, to bring and control any legal
action in connection with any alleged or threatened infringement by a Third Party of any of the Licensed Patents (other than Joint Patents) that is not a Product Infringement, and any related declaratory judgment, opposition, or similar action by a
Third Party alleging the invalidity, unenforceability or non-infringement of any of the Licensed Patents (other than Joint Patents), at its own expense as it reasonably determines appropriate. 

(d) Zai shall have the first right, but not the obligation, to enforce the Joint Patents in the Territory for any infringement that is not a
Product Infringement at its own expense as it reasonably determines appropriate. Cullinan shall have the first right, but not the obligation, to enforce the Joint Patents outside the Territory for any infringement at its own expense as it reasonably
determines appropriate. If the Party with the first right of enforcement in respect of Joint Patents under this Section 13.4(d) decides not to bring such legal action in any jurisdiction(s) subject to its first right, it shall so inform the
other Party promptly and the other Party shall have the right, but not the obligation, to bring and control any legal action in connection with such infringement in such jurisdiction(s) at its own expense as it reasonably determines appropriate.

 (e) Cullinan shall have the first right, but not the obligation, to bring and control any legal action in connection with any alleged or
threatened infringement by a Third Party of any of the Zai Patents (other than Joint Patents), which infringement adversely affects or is expected to adversely affect any Product in the Field outside the Territory, and any related declaratory
judgment, opposition, or similar action by a Third Party alleging the invalidity, unenforceability or non-infringement of any of the Zai Patents (other than Joint Patents) outside the Territory, at its own
expense as it reasonably determines appropriate. If Cullinan does not bring such legal action prior to the earlier of: (i) ninety (90) days following receipt or delivery of notice between the Parties regarding such alleged infringement, or
(ii) thirty (30) days before the deadline, if any, set forth in the Applicable Laws for the filing of such actions, or discontinues the prosecution of any such action after filing without abating such infringement, Zai shall have the right to
bring and control any legal action in connection with infringement at its own expense as it reasonably determines appropriate. Except as otherwise provided in this Section 13.4(e), Zai shall have the exclusive right, but not the obligation, to
bring and control any legal action in connection with any alleged or threatened infringement by a Third Party of any of the Zai Patents (other than Joint Patents), and any related declaratory judgment, opposition, or similar action by a Third Party
alleging the invalidity, unenforceability or non-infringement of any of the Zai Patents (other than Joint Patents), at its own expense as it reasonably determines appropriate.

 (f) At the request of the Party bringing an action related to Product Infringement or
otherwise as described in this Section 13.4, the other Party shall provide reasonable assistance in connection therewith, including by executing reasonably appropriate documents, cooperating in discovery and joining as a party to the action if
required by Applicable Laws to pursue such action, at each such Party’s sole cost and expense. In connection with an action related to Product Infringement or otherwise as described in this Section 13.4, the Party bringing the action shall
not enter into any settlement admitting the invalidity or non-infringement of, or otherwise impairing the other Party’s rights in the Licensed Patents, Zai Patents or Joint Patents, as applicable, without
the prior written consent of the other Party. The enforcing Party shall keep the non-enforcing Party reasonably informed of the status of any action it brought in connection with such Product Infringement or
otherwise as described in this Section 13.4. The non-enforcing Party shall be entitled to attend any substantive meetings, hearings, or other proceedings related to any such action pursued by the
enforcing Party. The enforcing Party shall provide the non-enforcing Party with copies of all pleadings and other documents to be filed with the court reasonably in advance and shall consider in good faith
reasonable and timely input from the non-enforcing Party during the course of the action. 
 (g) Any
recoveries resulting from enforcement action relating to a claim of Product Infringement or otherwise as described in this Section 13.4 shall be first applied against payment of the enforcing Party’s costs and expenses in connection
therewith and then the non-enforcing Party’s costs and expenses in connection therewith. [***]. 

13.5. Defense. 

(a) Each Party shall notify the other in writing of any allegations it receives from a Third Party that the Development, Manufacture, use,
Commercialization or other exploitation of any Licensed Compound or Product or any embodiment of any technology or intellectual property licensed by a Party under this Agreement infringes the intellectual property rights of such Third Party. Such
notice shall be provided promptly, but in no event after more than fifteen (15) days following receipt of such allegations. Such written notice shall include a copy of any summons or complaint (or the equivalent thereof) received regarding the
foregoing. Thereafter, the Parties shall promptly meet to consider the claim or assertion and the appropriate course of action and may, if appropriate, agree on and enter into a “common interest agreement” wherein the Parties agree to
their shared, mutual interest in the outcome of such potential dispute. Each Party shall assert and not waive the joint defense privilege with respect to all communications between the Parties. 

(b) As between the Parties, Zai shall have the first right, but not the obligation to control and be solely responsible for the defense of any
such suit against Zai, at Zai’s sole cost and expense; provided, however, Zai shall not enter into any compromise or settlement relating to such suit that (i) admits the invalidity or unenforceability of any Licensed Patents
or Joint Patents; or (ii) requires abandonment of any Licensed Patents or Joint Patents; or (iii) contemplates payment or other action by Cullinan or has a material adverse effect on Cullinan’s business, in all cases ((i) through
(iii)), without obtaining the prior written consent of Cullinan. 

  
 44 

 (c) If Zai decides not to bring such legal action subject to its first right, it shall so
inform Cullinan promptly and Cullinan shall have the right to bring and control any such legal action in connection with such infringement in the Territory at its own expense as it reasonably determines appropriate; provided, however,
Cullinan shall not enter into any compromise or settlement relating to such suit that (i) admits the invalidity or unenforceability of any Licensed Patents or Joint Patents; or (ii) requires abandonment of any Licensed Patents or Joint
Patents; or (iii) contemplates payment or other action by Zai or has a material adverse effect on Zai’s business, in all cases ((i) through (iii)), without obtaining the prior written consent of Zai. 

(d) Upon the defending Party’s request and at the defending Party’s expense, the
non-defending Party shall provide reasonable assistance to the defending Party for such defense and shall join such suit if deemed a necessary party. If the
non-defending Party does not join such suit, the defending Party shall keep the non-defending Party reasonably informed of the status of such suit. The non-defending Party shall be entitled to attend any substantive meetings, hearings, or other proceedings related to such suit. The defending Party shall provide the
non-defending Party with copies of all pleadings and other documents to be filed with the court reasonably in advance and shall consider in good faith reasonable and timely input from the non-defending Party during the course of the suit.

DISPUTE RESOLUTION 

15.1. General. The Parties recognize that a claim, dispute or controversy may arise relating to this Agreement or to the breach,
enforcement, interpretation or validity of this Agreement (a “Dispute”). Any Dispute, including Disputes that may involve the Affiliates of any Party, shall be resolved in accordance with this ARTICLE 15. 

15.2. Continuance of Rights and Obligations during Pendency of Dispute
Resolution. If there are any Disputes in connection with this Agreement, including Disputes related to termination of this Agreement under ARTICLE 14, all rights and obligations of the Parties shall continue until such time as any Dispute has

15.4. Arbitration. 

(a) If the Parties fail to resolve the Dispute through escalation to the Executive Officers under Section 15.3, and a Party desires to
pursue resolution of the Dispute, the Dispute shall be submitted by either Party for final resolution by arbitration under the Rules of Arbitration of the International Chamber of Commerce (“ICC Rules”), excepted as modified
herein. Any disputes concerning the propriety of the commencement of the arbitration or the scope or applicability of this agreement to arbitrate shall be finally settled by the arbitral tribunal. The arbitration shall be conducted by a tribunal of
three (3) arbitrators, each with at least fifteen (15) years of pharmaceutical industry experience. An arbitrator shall be deemed to meet this qualification unless a Party objects within ten (10) days after the arbitrator is
nominated. Within thirty (30) days after initiation of arbitration, each Party shall nominate one (1) arbitrator and the two (2) Party-nominated arbitrators shall nominate a third arbitrator, who shall serve as the chairperson of the
tribunal, within thirty (30) days of the second arbitrator’s appointment. The seat of arbitration shall be New York City, New York and the language of the proceedings, including all communications, shall be English. 

  
 48 

 (b) The Parties agree that any award or decision made by the arbitral tribunal shall be
final and binding upon them and may be enforced in the same manner as a judgment or order of a court of competent jurisdiction, and the Parties undertake to carry out any award without delay. The arbitral tribunal shall render its final award or
decision within nine (9) months from the date on which the request for arbitration by one of the Parties wishing to have recourse to arbitration is received by the ICC Secretariat. The arbitral tribunal shall resolve the Dispute by applying the
provisions of this Agreement and the governing law set forth in Section 16.5. 
 (c) By agreeing to arbitration, the Parties do not
intend to deprive any court of its jurisdiction to issue, at the request of a Party, a pre-arbitral injunction, pre-arbitral attachment or other order to avoid
irreparable harm, maintain the status quo, preserve the subject matter of the Dispute, or aid the arbitration proceedings and the enforcement of any award. Without prejudice to such provisional or interim remedies in aid of arbitration as may be
available under the jurisdiction of a competent court, the arbitral tribunal shall have full authority to grant provisional or interim remedies and to award damages for the failure of any Party to the dispute to respect the arbitral tribunal’s
order to that effect. 
 (d) EACH PARTY HERETO WAIVES: (I) ITS RIGHT TO TRIAL OF ANY ISSUE BY JURY, AND (II) ANY CLAIM FOR
ATTORNEY FEES, COSTS AND PREJUDGMENT INTEREST. 
 (e) Each Party shall bear its own attorney’s fees, costs, and disbursements arising
out of the arbitration, and shall pay an equal share of the fees and costs of the administrator and the arbitrators; provided, however, that the arbitrators shall be authorized to determine whether a Party is the prevailing party, and
if so, to award to that prevailing party reimbursement for any or all of its reasonable attorneys’ fees, costs and disbursements (including, for example, expert witness fees and expenses, photocopy charges, travel expenses, etc.), or the fees
and costs of the administrator and the arbitrators. 
 (f) Notwithstanding anything in this Section 15.4, in the event of a Dispute
with respect to (i) the validity, scope, enforceability or ownership of any Patent or other intellectual property rights, (ii) a matter for which this Agreement assigns decision-making to the Parties or to the JSC or requires the consent
of one or both of the Parties, (iii) the necessity of obtaining a Third Party license by Zai in the Territory in accordance with Section 9.4(c)(iii), or (iv) any antitrust, anti-monopoly or competition law or regulation, whether or
not statutory, and such Dispute is not resolved in accordance with Section 15.3, such Dispute shall not be submitted to an arbitration proceeding in accordance with this Section 15.4, unless otherwise agreed by the Parties in writing, and
instead, either Party may initiate litigation in a court of competent jurisdiction in any country in which such rights apply.

 MISCELLANEOUS 

16.1. Force Majeure. Neither Party shall be held liable to the other Party nor be deemed to have defaulted under or

of war (whether war be declared or not), insurrections, riots, civil commotions, strikes, lockouts or other labor disturbances, fire, floods, pandemics, epidemics or other acts of God or any other deity (or orders of any Governmental Authority

it be required to recognize, such assignment or transfer. 
 16.3. Severability. If any one or more of the provisions
contained in this Agreement is 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. The Parties shall in such an instance use their best efforts to replace the invalid, illegal or unenforceable provision(s) with valid, legal and enforceable
provision(s) which, insofar as practical, implement the purposes of this Agreement.

Without limiting the foregoing, Zai further agrees that (a) subcontracting shall not relieve Zai of any obligations under this Agreement (except to the extent satisfactorily performed by such subcontractor), and Zai shall remain responsible for

 Section 2.8: 
 Third Party
Technology Acquired after Effective Date. If after the Effective Date, Zai (or a Related Party) desires to use in connection with the Development, Manufacture or Commercialization of the Licensed Compound or a Product any Patents or Know-How acquired from a Third Party and other than Research Tools (such Patents and Know-How, “Third Party Technology,” and such Third Party, a
“Third Party Licensor”), the following shall apply: 
  

	 	a.	 Before the Third Party Technology is so used, Zai shall notify Cullinan in writing, including a description of
such Third Party Technology (such notice, the “Acquiring Party Notice”). Without limiting Section 2.8(d) below, to the extent that Zai has the right to grant a sublicense to such Third Party Technology to Cullinan or Taiho for
use in connection with the Development, Manufacture or Commercialization of the Licensed Compound or a Product by Cullinan in its territory (“Available Third Party Technology”), Zai shall include in such notice a description of all
payments and other obligations that would apply to Cullinan or Taiho if the Third Party Technology were to be licensed to Cullinan or Taiho hereunder (such payments and other obligations (including obligations relating to sublicensing, patent
matters, confidentiality, reporting, audit rights, indemnification and diligence, as applicable) owing to the Third Party Licensor, the “Pass-Thru Obligations”), accompanied by a copy of the relevant license or other agreement with
the applicable Third Party Licensor (such license or other relevant agreement, the “Pass-Thru Agreement”), [***]. 

  

	 	b.	 To the extent Taiho or Cullinan wishes to receive a license to any Available Third Party Technology disclosed
in the Acquiring Party Notice for use in connection with the Development, Manufacture or Commercialization of the Licensed Compound or a Product in territories in which Taiho or Cullinan has such rights with respect to the Licensed Compound and
Products, it shall so notify Zai in writing (such notice, the “Receiving Party Notice”). Upon receipt of the Receiving Party Notice, Zai shall grant (and hereby grants) to Taiho or Cullinan, as applicable, a license or sublicense
under the applicable Third Party Technology to use and exploit the same in connection with the Development, Manufacture or Commercialization of the Licensed Compound or a Product in territories in which Taiho or Cullinan has such rights with respect
to the Licensed Compound and Products, subject to the Pass-Thru Obligations (the “Pass-Thru License”). If requested by Zai, Taiho or Cullinan and Zai shall prepare in good faith and promptly execute a written agreement codifying the
terms of the Pass-Thru License or to the extent mutually agreed, work to put in place a separate agreement between the applicable Third Party and Zai under which the Third Party grants a direct license to Taiho or Cullinan, as applicable under the
Third Party [***]. Taiho and Cullinan, as applicable, shall comply with the Pass-Thru Obligations applicable to such Third Party Technology, in each case to the extent such Pass-Thru Obligations were described in the Pass-Thru Agreement (as
redacted). Such compliance by Taiho and Cullinan, as applicable, shall include taking such actions to comply with the Pass-Thru Obligations in such manner and on such timing as may be required to allow Taiho and Cullinan, as applicable, to comply
with its obligations under the license or other agreement with the applicable Third Party Licensor, as such obligations apply to activities of the Receiving Party. [***]. 

	 	c.	 Until Taiho or Cullinan, as applicable, provides a Receiving Party Notice, or to the extent Taiho or Cullinan
subsequently notifies Zai that it wishes to terminate the applicable Pass-Thru License, [***], as the case may be. In the event Taiho or Cullinan subsequently notifies Zai that it wishes to terminate the applicable Pass-Thru License, [***]. To the
extent Taiho or Cullinan does not provide a Receiving Party Notice with respect to the Third Party Technology, [***]. 

  

	 	d.	 Prior to such time as a Product has received Regulatory Approval in the United States and one of the EU5, if
Zai does not have the right to grant to Taiho or Cullinan a Pass-Thru License with respect to a particular Third Party Technology (i.e., as “Available Third Party Technology”) with respect to the Development, Manufacture and
Commercialization of the Licensed Compound and Product in the Taiho’s or Cullinan’s territory, [***]. Notwithstanding the foregoing, in the event that a Third Party Technology with respect to which Zai is unable to grant a Pass-Thru [***]
(such license, a “Direct License”), then to the extent that Taiho or Cullinan actually obtains such Direct License on such terms, Zai shall [***]. 

 

	 	e.	 Other than pursuant to and in accordance with the provisions of this Section 2.8, neither Party shall
[***]. For clarity, this Section 2.8 shall not apply to Patents or Know-How used by the Zai or a Related Party in connection with the Development, Manufacture or Commercialization of a Licensed Compound
or Product [***]. 

 Section 4.3(b): 

Regulatory Cooperation in the Territory. 
  

	 	i.	 Promptly following written request by Cullinan, Zai shall provide to Cullinan a copy of the final labeling for
the Product (including the Company Core Data Sheet) in the local language in the Territory in which Licensee or Related Party obtains Regulatory Approvals. Zai need supply such copy only once. 

 

	 	ii.	 In addition, Zai shall provide to Cullinan such information as Cullinan may reasonably request from time to
time, so that Cullinan may keep reasonably informed as to other Development and Regulatory activities and progress with respect to the Product. 

 Section 5.4: 

Taiho’s and Cullinan’s Right to Take Supply of Product Materials from Qualified CMO(s). 

(a) The Contracting Party shall provide to Cullinan a complete and correct copy of each Qualified CMO Supply Agreement within [***] days after the execution
thereof. For clarity, a Qualified CMO Supply Agreement shall refer [***]. 
 i) Upon request, the Contracting Party shall cooperate fully and
reasonably with Cullinan and Taiho, as applicable, to enable and facilitate the negotiation and execution by Cullinan and Taiho, as applicable, of a reasonable and customary supply agreement directly between Cullinan and Taiho, as applicable, and
each Qualified CMO for the timely supply to Cullinan and Taiho, as applicable, of the same Product Materials from such Qualified CMO on terms no less favorable than those in the applicable Qualified CMO Supply Agreement (including reasonable
technology transfer provisions, to permit Taiho, Cullinan or their designated suppliers to produce such Product Materials). Zai shall ensure that the Contracting Party authorizes the Qualified CMO to utilize on Taiho’s and Cullinan’s
behalf (and as needed, to make available to Taiho and Cullinan) all information of Zai and its Related Parties in the Qualified CMO’s possession necessary for the production of Product Materials identical to those being produced under the
applicable Qualified CMO Supply Agreements. In no event shall Zai nor a Related Party seek to restrict, impede or discourage any Qualified CMO from manufacturing Product for Taiho or Cullinan. 

(b) For clarity, and without limiting any of the foregoing, it is understood that Taiho and Cullinan may manufacture, or obtain from another source supply of,
some or all of its requirements of a Product (including, for clarity any modified formulation or dosage form of or packaging for a Product), or any Product Materials at any time and from time to time. If Taiho or Cullinan wishes to manufacture
itself, or have manufactured, a Product and/or Product Materials, in no event shall Zai nor any Related Party attempt to limit the transfer to Taiho, Cullinan or its designee of the production process for the manufacture of such Product or Product
Material, as applicable, including without limitation the manufacturing methods, test methods, specifications, materials, and other procedures, directions and controls associated with the manufacture and testing of such Product or Product Material,
as the case may be, used by the Qualified CMO, to the extent the Zai, such Related Party and/or such Qualified CMO Controls such parts of such production process. 

(c) The intent of this Section 5.4 is that Taiho and Cullinan be able to obtain supply of Product Materials produced by the Qualified CMO(s) in
sufficient quantities, on such timelines and otherwise as is reasonably necessary and customary for Taiho and Cullinan to Develop and Commercialize the Product outside the Territory without delay, and Zai shall cooperate fully and reasonably and
take such further actions as Taiho and Cullinan may reasonably request to achieve such objective, provided that this Section 5.4(c) shall not be construed to materially expand or alter Zai obligations under Sections 5.4(a) or (b) above.
