Notwithstanding anything to the contrary, if INCY materially breach’s this Agreement and Zai Lab has the right to terminate this Agreement in accordance with Section 9.2.1 (Termination for Material Breach) as a result of a dispute escalated and resolved subject to the dispute resolution procedures set forth in ARTICLE 12 (Dispute Resolution), then Zai Lab, in its sole discretion and upon written notice to INCY, will have the right to elect to either (a) terminate this Agreement with an immediate effect, or (b) not to terminate this Agreement; provided if Zai Lab elects to not terminate this Agreement, the Parties agree that, in addition to and without prejudice to any damages or remedies (including any equitable relief) that Zai Lab may have under this Agreement or otherwise, any and all payments payable by Zai Lab as of date of such election and during the remainder of the Term shall be reduced by [***].

9.2.2Termination for Convenience. At any time, Zai Lab may terminate this Agreement in its entirety by providing written notice of termination to INCY, which notice includes an effective date of termination at least [***] days after the date of the notice.

9.2.3Termination for Development or Commercial Diligence Failures.

9.2.4Termination for Bankruptcy. If either Party makes a general assignment for the benefit of creditors, appoints or suffers appointment of a receiver or trustee over all or substantially all of its property, files a petition under any bankruptcy or insolvency act or has any such petition filed against it which is not dismissed, discharged, bonded or stayed within [***] days after the filing thereof, the other Party may terminate this Agreement in its entirety effective immediately upon written notice to such Party. All rights and licenses granted under or pursuant to this Agreement by Zai Lab or INCY are, and will otherwise be deemed to be, for purposes of Section 365(n) of the U.S. Bankruptcy Code, licenses of right to “intellectual property” as defined under Section 101 of the U.S. Bankruptcy Code. The Parties agree that the terminating Party, insofar that it is a licensee

under this Agreement will retain and may fully exercise all of its rights and elections as a licensee under the U.S. Bankruptcy Code and any foreign counterparts thereto.

9.2.5Termination for Patent Challenge. If a Party or any of its Affiliates or Sublicensees, individually or in association with any other person or entity, challenges in a legal action or an administrative proceeding the validity, enforceability or patentability of any Patent that is licensed to the other Party under this Agreement, the Party who Controls such Patent may upon [***] days’ advance notice, terminate this Agreement in its entirety unless during such [***] period the subject challenge is permanently dismissed or withdrawn and is not thereafter reinstituted or continued; provided that in the event a Party’s Sublicensee initiates such challenge, the other Party who Controls such Patent many not terminate this Agreement if (a) such Party successfully causes such Sublicensee to abort such challenge within such [***] period, or (b) such Party (i) provides the other Party written notice of its intent to terminate its sublicense with such Sublicensee within such [***] period, and (ii) successfully terminates such sublicense within [***] days after the delivery of such notice. For clarity, a good faith contractual dispute brought by Zai Lab under this Agreement solely with respect to whether or not a particular INCY Patent Covers a Licensed Product, or its manufacture or use, in a Region for purposes of determining when the Royalty Term with respect to such Licensed Product in such Region has ended or a royalty-rate reduction occurs pursuant to Section 7.3.4 (Royalty Reduction) shall not be deemed a “challenge” so long as such dispute with respect to such INCY Patent is limited to such purpose and to determination of (y) the scope of such INCY Patent for purposes of determining whether such INCY Patent Covers such Licensed Product and (z) non-infringement of such Licensed Product of such INCY Patent, and Zai Lab does not dispute or challenge the validity, patentability, priority, inventorship, ownership or enforceability of such INCY Patent.

(a)Upon the expiration of a Royalty Term with respect to a Licensed Product in a Region(s), all licenses granted by INCY to Zai Lab for such Licensed Product in such Region(s) for which Zai Lab has paid all royalties and milestone payments due under this Agreement will be deemed fully paid up and irrevocable, but on a non-exclusive basis, except as provided under clauses (b) and (c) of this Section 9.3.1 (each a “Surviving License”).

(b)If INCY [***], the Commercialization portion only of the Surviving License for such Licensed Product in such Region(s) shall remain an exclusive license for a payment of the higher of: (i) an amount equal to [***] (as defined in this Agreement, but for Licensed Product manufactured by [***] taking the place of INCY in such definition, mutatis mutandis) of Licensed Product sold and counted in Net Sales by Zai Lab after expiration of such Royalty Term; or (ii) [***] of Net Sales of such Licensed

CERTAIN CONFIDENTIAL INFORMATION CONTAINED IN THIS DOCUMENT, MARKED WITH [***], HAS BEEN OMITTED BECAUSE IT IS BOTH (I) NOT MATERIAL AND (II) WOULD BE COMPETITIVELY HARMFUL IF PUBLICLY DISCLOSED.

Product in such Region(s) after expiration of such Royalty Term. Such Surviving License for Commercialization will remain exclusive until [***] days after any of such payments to INCY has become due but is not paid subject to a [***] days’ curing period (at the expiration of such curing period, where the payment has not been cured, such license automatically converts to non-exclusive).

(c)If INCY elects to supply to Zai Lab such Licensed Product for Commercialization in such Region(s) after the expiration of a Royalty Term for a Licensed Product in a Region(s) in accordance with Section 9.1.3 (Option to Obtain Supply After Expiration), upon and after the expiration of such Royalty Term pursuant to Section 7.3.2 (Royalty Term), the Commercialization portion only of the Surviving License for such Licensed Product in such Region(s) shall remain an exclusive license for a payment of the higher of: (i) an amount equal to [***] of Licensed Product supplied by INCY under Section 9.1.3 (Option to Obtain Supply after Expiration) after expiration of such Royalty Term; or (ii) [***] of Net Sales of such Licensed Product in such Region(s) after expiration of such Royalty Term, in each case of clause (i) and (ii), above, minus the amount paid to INCY under clause (a) of Section 9.1.3 (Option to Obtain Supply after Expiration). Such Surviving License for Commercialization will remain exclusive until [***] days after any of such payments to INCY has become due but is not paid subject to a [***] days’ curing period (at the expiration of such curing period, where the payment has not been cured, such license automatically converts to non-exclusive).

(d)For clarity, while any Surviving License remains exclusive, INCY will not, and will cause its Affiliates to not, directly or indirectly, through Third Party(ies), (i) Commercialize the subject Licensed Product(s) in the Field in the applicable Region(s), (ii) supply the subject Licensed Product(s) to any Third Party(ies) in the Field in the applicable Region(s) for Commercialization of the subject Licensed Product(s) in the Field in the applicable Region(s), or (iii) grant a license to any Third Party(ies) for the Commercialization of the subject Licensed Product in the Field in the applicable Region(s).

(e)Upon the termination of this Agreement in its entirety pursuant to Section 9.2 (Early Termination): (i) all Surviving Licenses will be deemed fully paid up and irrevocable, but on a non-exclusive basis, except as provided under clauses (b) and (c) of this Section 9.3.1; and (ii) all other licenses granted by INCY to Zai Lab will terminate and their corresponding rights under the INCY Patents and INCY Technology will revert to INCY. Upon the effective date of such termination, except as provided under clause (a), (b) and (c) of this Section 9.3.1, the licenses granted from INCY to Zai Lab under Section 6.1 (License to Zai Lab) will convert to non-exclusive and remain in effect for the limited duration of, and to the limited extent necessary to complete, the post-termination transition activities contemplated by this Section 9.3 (Effects of Termination).

9.3.2Transition. Upon the effective date of the termination of this Agreement, Zai Lab will:
