The following Development milestone payments will be paid only for the first Licensed Compound or Licensed Product to achieve the indicated milestone event. Following such payment, the subsequent repeated occurrence of the same milestone event by the same or another Licensed Compound or Licensed Product (and irrespective of whether a Licensed Product is Developed or Commercialized in two or more different dosage forms, dosage strengths or formulations) will not under any circumstances trigger any additional milestone payment as a result of such event.


*Milestone Event*		*Milestone Payment*
[*]		[*]

If a milestone event described above for any of [*] is not achieved for a Licensed Compound or Licensed Product but one or more of subsequent milestone events described above does occur for the same Licensed Compound or Licensed Product and is achieved, such earlier skipped Milestone Payment will then be due and payable.

5.3 Royalties. ZAI will pay to UCB, on a Licensed Product-by-Licensed Product basis, running royalties on Net Sales of Licensed Products in the Territory at the applicable royalty rates, as set forth in the following table:


*Aggregate Total of Annual Net Sales of a Product in the Territory*		*Royalty Rate*
With respect to the portion of annual Net Sales less than $[*]		[*]%

With respect to the portion of annual Net Sales equal to or greater than $[] but less than $[]		[*]%

With respect to the portion of annual Net Sales equal to or greater than $[*]		[*]%

For clarity, non-limiting examples of sample royalty calculations are set forth in Exhibit G to illustrate how royalties for Licensed Products are to be calculated, it being acknowledged and agreed that the sales numbers used in those examples are not intended to imply or represent any form of forecast or projection of actual sales results that may occur if one or more Products are approved and subsequently Commercialized in the Territory.

(a) Duration of Royalty Obligations. ZAI’s obligation to pay royalties under Section 5.3 will be in effect during the “Royalty Period” which begins on the date of First Commercial Sale of a Licensed Product in the Territory and shall expire on a Licensed Product-by-Licensed Product and country-by-country basis upon the later of:

(i) The expiration of the last-to-expire UCB Patent in such country having a Valid Claim that Covers such Licensed Product;

(ii) the expiration of all Regulatory Exclusivity Periods that apply to such Licensed Product in such country; or

(iii) ten (10) years after the First Commercial Sale of such Licensed Product in such country.

(b) Additional Provisions Regarding Royalties. For purposes of determining ZAI’s royalty payment obligations under Section 5.3, all Licensed Products [*] will be treated as the same Licensed Product; provided, however, that Licensed Products [*] will be considered as different from any Licensed Products [*]. In addition, ZAI’s royalty obligations under Section 5.3 will be subject to the following conditions:

(i) Only one royalty will be due and payable with respect to the same unit of Licensed Product;

(ii) Royalties when owed or paid hereunder will be non-refundable and non-creditable and not subject to set-off, except as expressly set forth herein;

(iv) No royalties shall accrue on the disposition of Licensed Product by ZAI or its Affiliates or Sublicensees for use in any Phase I Studies, Phase II Studies, Phase III Studies or Phase IV Studies;

(v) No royalties shall accrue on the distribution of Licensed Product in reasonable quantities by ZAI or its Affiliates or Sublicensees as free samples (whether for promotion or otherwise) or as donations (for example to non-profit institutions or government agencies for non-commercial purposes); and

(vi) Notwithstanding the definition of Licensed Product, in the event that ZAI or its Affiliates sells Licensed Product in other than final finished, packaged form (including without limitation sales of bulk active Licensed Compound) to a Third Party, the royalty obligations of this Section 5.3 shall be applicable to such sales of unfinished Licensed Product in the Territory.

(c) Reduction of Royalties due to Generic Competition. The royalty payment due and payable to UCB for Net Sales of a Licensed Product in a country pursuant to Section 5.3 will be reduced, on a Licensed Product-by-Licensed Product and country-by-country basis, by [*] of the amount otherwise due on those Net Sales of such Licensed Product in such country accrued after the launch of a Generic Product during a given calendar year in the event that total unit sales of one or more Generic Product(s) in such country during the same calendar year exceeds [*] of the total unit sales volume for such Product in that country during the same calendar year, as measured by IMS health data (or if such IMS data is not available, another appropriate end user level data base maintained by an independent Third Party). For clarity, the right to reduce royalty payments in any subsequent calendar years shall only apply if unit sales of Generic Product(s) in the relevant country remain at or above the [*] threshold in such subsequent calendar year(s).

(d) Reduction of Royalties due to Third Party Payment. If it is necessary for ZAI to obtain a license from a Third Party under any intellectual property rights controlled by such Third Party in a particular country in the Territory in order to use, import or sell a Licensed Product and ZAI obtains such

a license, ZAI shall have the right to deduct, from the royalty payment that would otherwise have been due pursuant to Section 5.3 with respect to the Net Sales of such Licensed Product in such country in a particular calendar quarter, an amount equal to [*] of the payment made by ZAI to such Third Party pursuant to such license during such calendar quarter; provided, that, in no event shall this Section 5.3(d) operate to reduce the royalty rates by more than [*] of what they otherwise would be without the application of this Section 5.3(d).

(e) Reduction of Royalties due to Patent Expiration. The royalty payment due and payable to UCB for Net Sales of a Licensed Product in a country pursuant to Section 5.3 will be reduced, on a Licensed Product-by-Licensed Product and country-by-country basis, by [*] of the amount otherwise due on those Net Sales of such Licensed Product in such country accrued after expiration of the last-to-expire Patents in such country having a Valid Claim that Covers such Licensed Product.

(f) Reports and Timing of Royalty Payments. Starting on the date of First Commercial Sale of a Licensed Product in the Territory, ZAI will furnish to UCB a quarterly written report for each subsequent calendar quarter showing the Net Sales of all Licensed Products sold by ZAI, its Affiliates and Sublicensees for which royalties are payable hereunder, and the royalties due UCB on such sales. Each such royalty report shall be due within [*] days after the end of the relevant calendar quarter. The royalty payments due under Section 5.3 for each calendar quarter will be due and payable to UCB on the same date that the royalty report for the calendar quarter is due. Each royalty report shall describe in reasonable detail (based upon the data then available to ZAI) the Net Sales of each Licensed Product (including, without limitation, all deductions specified in the Net Sales definition), as well as the calculation of such Net Sales in the relevant local currency and the calculation of the exchange rate into U.S. dollars, and the calculation of royalty payments due for the relevant calendar quarter. The information contained in each report under this Section 5.3(f) shall be considered Confidential Information of ZAI.

5.4 Sublicense Payments.

(a) In the event that ZAI sublicenses to any Third Party any rights to Develop, Manufacture and/or Commercialize a Licensed Compound and/or Licensed Product in the Field in whole or in part, ZAI shall pay to UCB (x) the Royalties set forth in Section 5.3 above on the amount of annual Net Sales of Product booked by such Third Party and (y) an election of the higher of (1) the Milestone payments set forth above applicable to such sublicense and (2) a percentage of any other revenues received by ZAI from such Third Party as follows, and UCB shall make such election on a sublicense-by-sublicense agreement basis at the time ZAI enters into such sublicense agreement:

(i) With respect to a sublicense granted with respect to a Licensed Product prior to [*], [*]%;

(ii) With respect to a sublicense granted with respect to a Licensed Product prior to [*], [*]%; or

(iii) With respect to a sublicense granted with respect to a Licensed Product after [*], [*]%;

(b) “Sublicense Payments” means all payments received by ZAI from its Third Party sublicensee to the extent attributable to the grant to such Third Party of a sublicense under the license granted by UCB to ZAI under this Agreement, but excluding payment for: [*].

5.5 Payment Terms. This Section 5.5 will apply to all payments to be made by one Party to the other hereunder.

(a) Manner of Payment. All payments to be made by one Party to the other Party under this Agreement shall be made in United States dollars and by bank wire transfer in immediately available funds to such bank account as may be designated in writing by such Party from time to time. In the case

of royalties due on sales of Licensed Product outside the United States, the exchange rate to be used in computing on a monthly basis the applicable royalty due UCB in U.S. dollars shall be made at the monthly rate of exchange utilized by ZAI in its worldwide accounting system, prevailing on the third to the last business day of the month preceding the month in which such sales are recorded.

(b) Records and Audits. ZAI will maintain (and will cause its Affiliates and/or Sublicensees to maintain) accurate books and records of accounting to document the sales of Licensed Products and the calculation of royalties payable to UCB in the Territory.

Access to such books and records shall be during normal business hours and upon reasonable prior notice; provided that in no event will any such audits or inspections be conducted more frequently than [*]. The auditors will, upon request, enter into a confidentiality agreement as reasonably requested by ZAI. The auditors will be permitted to disclose to UCB only whether the royalty reports are correct or incorrect, and the details and amounts of any discrepancies. The auditors will also provide to ZAI, upon request, a copy of any audit reports and findings that are provided to UCB as a result of such inspection. If the auditors correctly identify any underpayments or overpayments, the amount of any underpayments will be paid to UCB by ZAI within [*] of notification of the results of such inspection, and any overpayments will be fully creditable against amounts payable to UCB in subsequent periods. UCB will be solely responsible for the costs and expenses of any such audit inspections, except that in the event of an underpayment of aggregate royalties due and payable to UCB for a calendar year of more than [*] of the total amount properly due, ZAI will reimburse UCB for the reasonable documented audit fees expenses charged by the auditors for such audit inspection. For clarity, upon the expiration of [*] following the end of any calendar year, absent willful misconduct or fraud by ZAI or any of its Affiliates or Sublicensees, the calculation of royalties payable to a UCB under this Agreement with respect to such calendar year shall become binding and conclusive upon the Parties and their Affiliates, and ZAI (and its Affiliates and Sublicensees) and UCB and its Affiliates shall be released from any liability or accountability with respect to royalties due or overpayments made under this Agreement for sales of Licensed Products during such calendar year.

(c) Taxes. UCB shall be liable for all income and other taxes (including interest) imposed upon any payments made by ZAI to UCB pursuant to this Agreement. If applicable laws, rules or regulations require the withholding of such taxes, ZAI shall make such withholding payments and shall subtract the amount thereof from the payments due UCB. ZAI shall submit to UCB appropriate proof of payment of the withheld taxes as well as the official receipts within a reasonable period of time. ZAI shall, upon request, provide UCB with reasonable assistance in order to assist UCB in seeking the benefit of any present or future tax exemptions and/or treaties against double taxation which may apply to any payments due UCB under this Agreement.

(d) Interest Due. If any uncontested amount properly due and payable to a Party under this Agreement is overdue, then the paying Party will also pay interest on the amount unpaid amount accrued at the annual rate USD London Interbank Offered Rate (LIBOR) 3 months plus [*] from the date of payment was due.

During the Term, ZAI shall not have the right to disclose UCB’s Format Confidential Information to any of its Affiliates, Sublicensees and/or Third Party consultants and contractors without [*] a written agreement of confidentiality and non-use containing terms at least as restrictive as those set forth in this Agreement. ZAI shall remain responsible for and liable hereunder with respect to any breach caused by its Affiliates, Sublicensees and/ or Third Party consultants or contractors.

(f) Other Permitted Disclosures. Each Party shall have the limited right to disclose the other Party’s Confidential Information if and solely to the extent reasonably necessary (as reasonably determined based upon the advice of such Party’s legal counsel) to be disclosed (1) to Third Parties and their respective legal counsel with whom such Party is negotiating a permitted assignment under Section 12.10, (2) to potential and actual licensees/sublicensees (and their legal counsel) of the license grant in Section 2.1 or 11.6(a)(v) and other collaborators (and their legal counsel), and/or (3) to accredited investors, qualified institutional buyers, and qualified purchasers and their legal counsel (as such terms are defined in the U.S. Securities Act of 1933 and/or the U.S. Securities Exchange Act of 1934, as amended). Prior to making any such disclosure under this Section 9.1(f), such Party shall ensure that the recipient is subject to written obligations of confidentiality and non-use that are no less restrictive than those set forth in this Agreement, and such Party will limit the content and timing of any such disclosure as much as reasonably possibly. Such Party shall remain responsible for and liable hereunder with respect to any breach caused by any of the foregoing.

9.2 Publications. ZAI and UCB each acknowledge the other Party’s interest in publishing the results of its research in order to obtain recognition within the scientific community and to advance the state of scientific knowledge. However, each Party also recognizes their mutual interest in obtaining valid patent protection and in protecting business interests and trade secret information. Consequently, in the event that a Party wishes to make a publication (including without limitation abstracts, papers, or verbal public presentations) related to the discovery, Development, Manufacture or Commercialization of Licensed Compounds and/or Licensed Products, it shall first deliver to the other Party a copy of the proposed publication (or an outline in the case of a planned verbal presentation) at least [*] days prior to submission for publication or presentation. The reviewing Party shall have the rights (1) to request modifications to the publication or presentation for patent reasons, trade secret reasons or business reasons and/or (2) to request a reasonable delay in publication or presentation in order to protect patentable information. If the reviewing Party requests modifications to the publication or presentation, the publishing Party shall edit such publication to prevent disclosure of trade secret or proprietary business information identified by the reviewing Party prior to submission of the proposed publication or presentation. If the reviewing Party requests a delay, the publishing Party shall delay submission or presentation for a period of [*] days to enable patent applications protecting each Party’s rights in such information to be filed in accordance with Section 7.1. Upon expiration of such [*] days, the publishing Party shall be free to proceed with the publication or presentation, subject to compliance with any requests for modification as provided above. However, UCB agrees that it shall not (and shall ensure that its Affiliates and Third Party contractors do not) publish or otherwise publicly disclose in any publication or presentation of any data or information regarding [*] at any time [*].

9.3 Disclosure of Agreement Terms. Promptly after the Effective Date, the Parties shall issue a joint press release in the form attached hereto as Exhibit H. No other public disclosure of the non-public terms and conditions of this Agreement may be made by either Party, without the prior written consent of the other Party. However, each Party shall have the limited right to disclose the non-public terms and conditions of this Agreement to its Affiliates and/or if and solely to the extent reasonably necessary (as reasonably determined based upon the advice of such Party’s legal counsel) to be disclosed (1) to Third Parties and their respective legal counsel with whom such Party is negotiating a permitted assignment under Section 12.10, (2) to potential and actual licensees/sublicensees (and their legal counsel) of the license grant in Section 2.1 or 11.6(a)(v) and other collaborators (and their legal counsel), and/or (3) to accredited investors, qualified institutional buyers, and qualified purchasers and their legal counsel (as such terms are defined in the U.S. Securities Act of 1933 and/or the U.S. Securities Exchange Act of

1934, as amended.). Prior to making any such disclosure under this Section 9.3, such Party shall ensure that the recipient is subject to written obligations of confidentiality and non-use that are no less restrictive than those set forth in this Agreement, and such Party will limit the content and timing of any such disclosure as much as reasonably possible to avoid and/or minimize the disclosure of competitively sensitive information. However, nothing in this Section 9.3 shall prohibit a Party from making such disclosures if and to the extent reasonably required to comply with applicable federal or state securities laws or any rule or regulation of any nationally recognized securities exchange; provided that in such event, the disclosing Party shall notify and consult with the other Party prior to such required disclosure and shall diligently seek confidential treatment to the fullest extent available.

9.4 Relationship to the Confidentiality Agreement. This Agreement supersedes that certain mutual “Confidentiality Agreement” between the Parties (and/or its Affiliates) dated [*]; provided that all “Confidential Information” (as defined in that agreement) that was disclosed or received by the Parties thereunder will also be deemed to be “Confidential Information” for purposes of this Agreement and will be subject to the terms and conditions of this Agreement.

10. Warranties; Limitations of Liability; Indemnification.

10.1 Representations and Warranties. Each Party hereby represents and warrants to the other Party as of the Effective Date that: (i) it is a corporation or limited liability company duly organized, validly existing, and in good standing under applicable laws; (ii) it has obtained all necessary consents, approvals and authorizations of all governmental authorities and other persons or entities required to be obtained by it in connection with this Agreement; (iii) the execution, delivery and performance of this Agreement have been duly authorized by all necessary corporate action on its part; and (iv) it has the legal right and power to enter into this Agreement, to extend the rights and licenses granted or to be granted to the other in this Agreement, and to fully perform its obligations hereunder.

10.2 Additional Representations and Warranties of UCB. UCB hereby represents and warrants to ZAI as of the Effective Date that, except as otherwise disclosed in writing by UCB on or before the Effective Date: (i) UCB Controls the UCB IP and is entitled to grant the licenses to ZAI specified herein with respect thereto; (ii) UCB has not granted to any Third Party any rights or licenses under the UCB IP that would conflict with the licenses granted to ZAI hereunder; (iii) UCB has disclosed to ZAI all prior art that is material to the patentability of and/or freedom to operate with respect to any existing UCB Patents, in whole or in part; (iv) it has obtained a present written assignment to UCB of all rights to the existing UCB Patents from the inventors named thereof; (v) there are no claims, judgments or settlements against or owed by UCB, and to the best of its knowledge no pending or threatened claims or litigation, relating to the UCB Patents or UCB Know-How or the Licensed Compound; (vi) UCB has not received any written notice from any Third Party asserting or alleging that the development of UCB IP or the Licensed Compound prior to the Effective Date infringed or misappropriated the intellectual property rights of such Third Party; (vii) to UCB’s knowledge, the development of UCB IP and the Licensed Compound prior to the Effective Date did not infringe any valid intellectual property rights owned or possessed by any Third Party and did not breach any obligation of confidentiality or non-use owed by such Party to a Third Party; (viii) to UCB’s knowledge, UCB does not own any Patents or Know-How, other than UCB IP, that would be necessary for the Development, Manufacture and/or Commercialization of the Licensed Compound or Licensed Product; and (ix) to UCB’s knowledge, the use of the UCB IP and the Development of the Licensed Compound and Licensed Product as contemplated by the Parties as of the Effective Date will not infringe or misappropriate the intellectual property rights of any Third Party.

10.3 Disclaimers. Without limiting the respective rights and obligations of the Parties expressly set forth herein, each Party specifically disclaims any guarantee that any Licensed Products will be successful, in whole or in part. The failure of the Parties to successfully Develop or Commercialize a Licensed Product will not, of itself, constitute a breach of this Agreement. EXCEPT AS OTHERWISE EXPRESSLY PROVIDED IN THIS AGREEMENT, THE PARTIES MAKE NO REPRESENTATIONS AND EXTEND NO WARRANTY OF ANY KIND, EITHER EXPRESS OR IMPLIED, WITH RESPECT TO ANY UCB IP, ZAI BACKGROUND IP, DEVELOPMENT IP, LICENSED COMPOUNDS, MATERIALS, LICENSED PRODUCTS, PATENT RIGHTS OR KNOW-HOW, INCLUDING WARRANTIES OF VALIDITY OR ENFORCEABILITY OF ANY RIGHTS, TITLE, QUALITY, MERCHANTABILITY, FITNESS FOR A PARTICULAR USE OR PURPOSE, PERFORMANCE, AND NONINFRINGEMENT OF ANY THIRD PARTY PATENTS OR OTHER INTELLECTUAL PROPERTY RIGHTS.

10.4 No Consequential Damages. IN NO EVENT WILL EITHER PARTY HAVE ANY CLAIMS AGAINST OR LIABILITY TO THE OTHER PARTY WITH RESPECT TO ANY INDIRECT, PUNITIVE, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES (INCLUDING ANY CLAIMS FOR LOST PROFITS OR REVENUES) ARISING UNDER OR IN CONNECTION WITH THIS AGREEMENT UNDER ANY THEORY OF LIABILITY, EVEN IF SUCH PARTY HAS BEEN INFORMED OR SHOULD HAVE KNOWN OF THE POSSIBILITY OF SUCH DAMAGES; PROVIDED THAT THE FOREGOING LIMITATION SHALL NOT APPLY WITH RESPECT TO INDEMNITY FOR THIRD PARTY CLAIMS AS PROVIDED IN SECTION 10.5 OR EITHER PARTY’S BREACH OF CONFIDENTIALITY AND NON-USE OBLIGATIONS HEREUNDER.

10.5 Indemnification.

(a) Indemnification by ZAI. ZAI will indemnify, defend and hold harmless UCB, its Affiliates, and their respective directors, officers, employees and agents (collectively, “UCB Indemnitees”) from and against any and all claims, demands, judgments, losses, damages, liabilities, costs and expenses (including reasonable attorneys’ fees and expenses) (collectively, “Liabilities”) arising out of or in connection with any and all Third Party claims relating to: (i) any gross negligence, willful misconduct or breach of this Agreement (including its representations and warranties made under this Agreement) by ZAI or any of its Affiliates or Sublicensees; or (ii) the Development, Manufacture or Commercialization by ZAI or any of its Affiliates or Sublicensees of any Licensed Compounds or Licensed Products, except in each case to the extent such Liabilities result from the gross negligence or willful misconduct of UCB or any of the UCB Indemnitees.

(b) Indemnification by UCB. UCB will indemnify, defend and hold harmless ZAI, its Affiliates, and their respective directors, officers, employees and agents (collectively, “ZAI Indemnitees”) from and against any and all Liabilities arising out of or in connection with any and all Third Party claims relating to any gross negligence, willful misconduct or breach of this Agreement (including its representations and warranties made under this Agreement) by UCB, except to the extent such Liabilities result from the gross negligence or willful misconduct of ZAI or any of the ZAI Indemnitees.

(c) Procedures. In the event that any Party intends to claim indemnification under this Section 10.5 with respect to a Liability, it shall promptly notify the other Party in writing of any such alleged Liability. The indemnifying Party shall have the right to control the defense thereof with counsel of its choice; provided, however, that the indemnified Party shall have the right to retain its own counsel, (with the fees and expenses to be paid by the indemnifying Party), if representation by the counsel retained by the indemnifying Party would be inappropriate due to actual or potential differing interests between the Parties in such proceeding. The affected Indemnitees shall, upon request, cooperate reasonably with the indemnifying Party and its legal representatives in the investigation and defense of any action, claim or liability covered by this Section 10.5. Neither Party may settle any claim or action related to a Liability without the consent of the other Party, if such settlement would (i) impose any

monetary obligation on the other Party (unless the indemnifying Party agreed to be solely responsible for such monetary obligation), (ii) constitute an admission of guilt or wrong-doing by the other Party, or (iii) require the other Party to submit to an injunction or otherwise limit the other Party’s rights under this Agreement. Any payment made by the indemnified Party to settle any such claim or action without the indemnifying Party’s consent shall be at indemnified Party’s own cost and expense.

10.6 Insurance. Each Party will maintain at its sole cost and expense, an adequate liability insurance or self-insurance program (including product liability insurance) to protect against potential liabilities and risk arising out of activities to be performed under this Agreement and any agreement related hereto and upon such terms (including coverages, deductible limits and self-insured retentions) as are customary in the U.S. pharmaceutical industry for the activities to be conducted by such Party under this Agreement. The coverage limits set forth herein will not create any limitation on a Party’s liability to the other under this Agreement.

11. Term and Termination.

11.1 Term. This Agreement will commence as of the Effective Date and, unless sooner terminated in accordance with the terms hereof, will continue in effect until the expiration of ZAI’s royalty obligations to UCB under Section 5.3 in all countries in the Territory (the “Term”). However, effective upon the expiration of ZAI’s royalty obligations to UCB with respect to a given Licensed Product in a given country in the Territory: (i) the licenses granted to ZAI in Section 2.1 under the UCB IP will become fully paid up, irrevocable, royalty-free and non-exclusive with respect to such Licensed Product in such country; and (ii) ZAI and its Affiliates and Sublicensees shall have the right to continue to Commercialize the relevant Licensed Product in such country without further obligation to UCB.

11.2 Discretionary Termination by ZAI. ZAI shall have the unilateral right to terminate this Agreement (with or without cause) by providing UCB with [*] days’ prior written notice to that effect.

11.3 Termination for Breach. Each Party shall have the unilateral right to terminate this Agreement at any time during its Term by providing written notice to that effect if the other Party is in breach of one or more of its material obligations hereunder and has not cured such breach within [*] days after the date of such notice; provided, however, that the period for curing the breach to avoid termination shall only be [*] business days in the case of a breach solely due to failure by a Party to make an uncontested payment when properly due hereunder. In the event of a good faith dispute with respect to the existence of a material breach, the cure period shall be tolled until such time as the dispute is resolved pursuant to Section 12.1.

11.4 Termination Upon Bankruptcy.

(a) Termination. Each Party shall have the unilateral right to terminate this Agreement at any time during its Term by providing written notice with immediate effect in the event that: (i) the other Party files in any court or agency pursuant to any statute or regulation of any state, country or jurisdiction, a petition in bankruptcy or insolvency or for reorganization or for an arrangement or for the appointment of a receiver or trustee of that Party or of all or substantially all of its assets, or (ii) if the other Party is served with an involuntary petition against it, filed in any insolvency proceeding, and such petition is not dismissed within [*] days after the filing thereof, or (iii) if the other Party proposes or is a party to any dissolution or liquidation, or (v) if the other Party makes an assignment of all or substantially all of its assets for the benefit of its creditors.

(b) Consequences of Bankruptcy. All rights and licenses granted under or pursuant to this Agreement by ZAI or UCB or their Affiliates 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 non-insolvent Party (and its Affiliates and sublicensees) as licensees of such rights under this Agreement, will retain and may fully exercise all of its rights and elections under the U.S. Bankruptcy Code and any foreign counterparts thereto.

11.5 Termination for challenge to the Patents. In the event that either Party or any of its Affiliates or (Sub)licensees, anywhere in the world, institutes, prosecutes or otherwise participates in (or in any way aids any Third Party in instituting, prosecuting or participating in), at law or in equity or before any administrative or regulatory body, including the U.S. Patent and Trademark Office or its foreign counterparts, any claim, demand, action or cause of action for declaratory relief, damages or any other remedy, or for an enjoinment, injunction or any other equitable remedy, including any interference, re-examination, opposition or any similar proceeding but excluding in response to any infringement claims first filed by the other Party, alleging that any claim in any Patent Rights Controlled by the other Party is invalid, unenforceable or otherwise not patentable, such other Party shall have the right to terminate this Agreement, including the rights of any (Sub)licensees, on [*] day written notice to the first Party, unless such first Party withdraws or causes the withdrawal of such proceedings within such [*]-day period.

11.6 Effects of Termination. The rights and obligations of the Parties upon termination of this Agreement shall be governed by the terms and conditions set forth in this Section 11.6 and in Section 11.7.

(a) Mutual Termination, Termination for Convenience, Force Majeure. In the event of termination of this Agreement under Section 11.2 or 12.15, or by the Parties’ mutual agreement:

(i) Except as may otherwise be agreed in writing by the Parties, ZAI will be responsible at its own expense for an orderly wind-down, in accordance with accepted pharmaceutical industry norms and ethical practices, of any then on-going clinical studies for which it has responsibility.

(ii) All licenses and rights granted by UCB to ZAI hereunder (including, without limitation, in Section 2.1) will terminate and such licenses and rights shall revert to UCB (except for those that expressly survive any such termination hereunder), and ZAI and its Affiliates and Sublicensees will have no further rights to use any UCB IP. ZAI shall promptly return to UCB (or as directed by UCB destroy and certify to UCB in writing as to such destruction) all of UCB’s Confidential Information and any Materials constituting UCB Know-How that are in ZAI’s or its Affiliates’ or Sublicensees’ possession or control.

(iii) [*] the Licensed Compounds and/or Licensed Products that are [*] will be [*].

(iv) ZAI will [*] (it being understood that the foregoing [*] or [*].

(v) ZAI shall [*]. [*] to the extent that [*] and/or [*]. In addition, (1) UCB will [*], which include [*], (2) the provisions of [*] and [*], except that ZAI shall [*], (3) the [*] as set forth in [*] with respect to [*], and (4) UCB will [*] thereto.

(vi) Should ZAI or any of its Affiliates have any remaining inventory of Licensed Compound and/or Licensed Product ZAI will transfer such Licensed Compound or Licensed Product to UCB “AS IS” at a price equal to [*].

(b) Termination pursuant to Diligence Failure or for Material Breach, challenge to the UCB Patents or Bankruptcy of ZAI. In the event of termination of this Agreement by UCB under Section 4.6, 11.3, 11.4 or 11.5:

(iii) [*] the Licensed Compounds and/or Licensed Products that are [*] will be [*].

(iv) ZAI will [*] (it being understood that the foregoing [*] or [*]).

(c) Termination for Material Breach, Challenges of ZAI Patents or Bankruptcy of UCB. In the event of termination of this Agreement by ZAI under Section 11.3, 11.4 or 11.5:

(i) To the extent permitted under applicable law, the licenses granted by UCB to ZAI under Section 2.1 shall continue in full force and effect on a transferable basis and ZAI’s payment obligation under Section 5.2 through 5.5 following the date of such termination shall continue in full force and effect but [*], provided however that in the event of a dispute between the Parties as to whether grounds for termination pursuant to Section 11.3 have arisen, the [*] shall not apply unless and until the dispute is resolved in ZAI’s favor in accordance with Section 12.1 and UCB fails to comply with the arbitrator’s decision within [*] days following such decision and fails to remedy its breach of this Agreement within such [*] day period, following which the [*] shall apply prospectively in respect of [*].

11.7 Survival. Except as otherwise set forth in Section 6, the following provisions (as well as any other provision which by its terms is clearly intended to survive termination or expiration of this Agreement) will survive termination or expiration of this Agreement: Sections [*]. Termination or expiration of this Agreement will not relieve the Parties of any liability or obligation which accrued hereunder prior to the effective date of such termination or expiration nor preclude either Party from pursuing all rights and remedies it may have hereunder or at law or in equity with respect to any breach of this Agreement nor prejudice either Party’s right to obtain performance of any obligation. All other rights and obligations will terminate upon termination or expiration of this Agreement.

11.8 Change of Control.

(a) In the event that a Party is subject to a Change of Control (as defined below) such Party, or its successor in interest shall remain subject to all of the terms and conditions of this Agreement and shall, within thirty (30) days after the occurrence of such event, provide the other Party with a written certification signed on behalf of the affected Party or its successor in interest confirming such Party’s (or

its successors) agreement to be bound by and perform its obligations under this Agreement. In the event that the Party undergoing a Change of Control fails to provide such written certification, or if the other Party reasonably determines, based on its assessment of available objective factual considerations, that the affected Party (or its successor in interest) will not be able to perform any of its obligations under this Agreement in accordance with the terms hereof, it shall promptly notify the affected Party in writing to that effect. The Parties shall then promptly meet to negotiate in good faith a mutually acceptable reallocation of responsibilities and/or amendments or other modification of this Agreement to address the relevant obligations of the Party undergoing the Change of Control (or its successor).

(b) As used in this Section 11.8, the term “Change of Control” means, with respect to a Party, the occurrence of any of the following events: (i) the acquisition by any Third Party (or a group of Third Parties acting in concert), whether in a single transaction or a series of transactions, of beneficial ownership of securities of such Party representing more than fifty percent (50%) of the combined voting power of such Party’s then outstanding securities entitled to vote generally in the election of directors; (ii) the consummation of a merger or consolidation of such Party with a Third Party, other than a merger or consolidation which would result in such Party’s voting securities outstanding immediately prior thereto continuing to represent (either by remaining outstanding or by being converted into voting securities of the surviving entity) more than fifty percent (50%) of the combined voting power of such Party’s voting securities or such surviving entity’s voting securities outstanding immediately after such merger or consolidation; or (iii) the bona fide sale, lease, transfer, exclusive license or other disposition, whether in a single transaction or series of related transactions, by such Party (or its Affiliates) of all or substantially all the assets of (A) such Party and its subsidiaries taken as a whole or (B) such Party’s subsidiaries, except in the case of both (A) and (B) if such sale, lease, transfer, exclusive license or other disposition is to a majority owned (direct or indirect) subsidiary of such Party.

12. General Provisions.

12.1 Dispute Resolution. The Parties shall negotiate in good faith and use reasonable efforts to resolve or settle any dispute, controversy or claim arising from or related to this Agreement or the breach thereof. In the event that such dispute, controversy or claim is not resolved on an informal basis within twenty (20) days, any Party may, by written notice to the other, have such dispute referred to senior executives having decision-making authority on behalf of such Party (but not any member of the JSC or Development Forum), who shall attempt in good faith to resolve such dispute for a thirty (30) day period following receipt of such written notice. If the Parties do not fully settle by the foregoing process, and a Party then wishes to pursue the matter, each such dispute, controversy or claim that is not an Excluded Claim (as defined below) shall be finally resolved by binding arbitration in accordance with the [*] of the [*], and the procedures set forth in Exhibit I, attached hereto. Judgment on the arbitration award may be entered in any court having jurisdiction thereof. As used in this Section 12.1, the term “Excluded Claim” means a dispute, controversy or claim that concerns (i) the validity or infringement of a patent, trademark or copyright; or (ii) any antitrust, anti-monopoly or competition law or regulation, whether or not statutory. For clarity, the foregoing dispute resolution mechanism shall not apply to any decision before the JSC, over which ZAI shall have the final decision making authority pursuant to Section 3.2(d).

12.2 Relationship of Parties. The relationship of the Parties hereto is that of independent contractors. Nothing in this Agreement is intended or will be deemed to constitute a partnership, agency, employer-employee or joint venture relationship between the Parties. No Party will incur any debts or make any commitments for the other, except to the extent, if at all, specifically provided therein. There are no express or implied third party beneficiaries hereunder.

12.3 Compliance with Law. Each Party will perform or cause to be performed any and all of its obligations or the exercise of any and all of its rights hereunder in good scientific manner and in compliance with all applicable law.

12.4 Governing Law. This Agreement and any dispute regarding the performance or breach hereof will be governed, interpreted and construed in accordance with the laws of the State of New York, without respect to its conflict of laws rules.

12.5 Counterparts; Facsimiles. This Agreement may be executed in two or more counterparts, each of which will be deemed an original, and all of which together will be deemed to be one and the same instrument. The execution and delivery of facsimile or PDF copies of this Agreement by the Parties will constitute a legal, valid and binding execution and delivery of this Agreement.

12.6 Headings. All headings in this Agreement are for convenience only and will not affect the meaning of any provision hereof.

12.7 Waiver of Rule of Construction. Each Party has had the opportunity to consult with counsel in connection with the review, drafting and negotiation of this Agreement. Accordingly, the rule of construction that any ambiguity in this Agreement will be construed against the drafting party will not apply.

12.8 Interpretation. “Herein,” “hereby,” “hereunder,” “hereof” and other equivalent words refer to this Agreement as an entirety and not solely to the particular portion of this Agreement in which any such word is used. References to any Articles or Sections include Articles, Sections and subsections that are part of the related Article or Section (e.g., a section numbered “Section 2.1” would be part of “Article 2”, and references to “Section 2.1” would also refer to material contained in the subsection described as “Section 2.1(a)”).

12.9 Binding Effect. This Agreement will inure to the benefit of and be binding upon the Parties and their respective lawful successors and assigns.

12.10 Assignment. This Agreement may not be assigned by either Party, nor may either Party delegate its obligations or otherwise transfer licenses or other rights created by this Agreement, except as expressly permitted hereunder or otherwise without the prior written consent of the other Party, which consent will not be unreasonably withheld, delayed or conditioned; provided that, without any requirement for consent, (i) ZAI may assign this Agreement to an Affiliate or to its successor in connection with the merger, consolidation, or sale of all or substantially all of its stock or assets or that portion of its business pertaining to the subject matter of this Agreement, and (ii) UCB may assign this Agreement to an Affiliate or to its successor in connection with the merger, consolidation, or sale of all or substantially all of its stock or assets or that portion of its business pertaining to the subject matter of this Agreement; provided, however, it is expressly understood and agreed that any such assignment shall not relieve ZAI of any of its obligations hereunder.

12.11 Notices. All notices, requests, demands and other communications required or permitted to be given pursuant to this Agreement will be in writing and will be deemed to have been duly given upon the date of receipt if delivered by hand, recognized international overnight courier, confirmed facsimile transmission, or registered or certified mail, return receipt requested, postage prepaid to the following addresses or facsimile numbers:

Either Party may change its designated address and facsimile number by notice to the other Party in the manner provided in this Section 12.11.

12.12 Amendment and Waiver. This Agreement may be amended or modified only by means of a written instrument signed by both Parties. The waiver by either Party hereto of any right hereunder, or of any failure of the other Party to perform, or of any breach by the other Party, shall only be effective if expressly made in writing. Any waiver of any rights or failure to act in a specific instance will relate only to such instance and will not be construed as an agreement to waive any rights or fail to act in any other instance, whether or not similar.

12.13 Severability. In the event that any provision of this Agreement will, for any reason, be held to be invalid or unenforceable in any respect, such invalidity or unenforceability will not affect any other provision hereof, and the Parties will negotiate in good faith to modify this Agreement to preserve (to the extent possible) their original intent.

12.14 Entire Agreement. This Agreement is the sole agreement with respect to the subject matter and supersedes all other agreements and understandings between the Parties with respect to the same subject matter. The Exhibits to this Agreement are expressly incorporated herein by reference and shall be deemed a part of this Agreement.

12.15 Force Majeure. Failure of any Party to perform its obligations under this Agreement (except the obligation to make payments when properly due) shall not subject such Party to any liability or place them in breach of any term or condition of this Agreement to the other Party to the extent (and only to the extent) that such failure is due to fire, explosion, flood, drought, war, terrorism, riot, sabotage, embargo, strikes or other labor trouble, failure of suppliers, a national health emergency, compliance with any order or regulation of any government entity acting with color of right, or any other cause beyond the reasonable control of such non-performing Party and which is not caused by the negligence, intentional conduct or misconduct of the non-performing Party (each such event or cause referred to as “force majeure”). The Party affected shall promptly notify the other Party of the condition constituting force majeure as defined herein and shall exert reasonable diligent efforts to eliminate, cure or overcome any such event of force majeure and to resume performance of its obligations with all possible speed. If a condition constituting force majeure as defined herein exists for more than ninety (90) consecutive days, the Parties shall meet to negotiate a mutually satisfactory resolution to the problem, if practicable. The foregoing notwithstanding, nothing herein shall require any Party to settle on terms unsatisfactory to such Party any strike, lock-out or other labor difficulty, any investigation or proceeding by any public authority or any litigation by any Third Party.

12.16 Further Actions. Each Party hereby agrees to execute, acknowledge and deliver such further instruments, and to do all other acts, as may be necessary or appropriate in order to carry out the purposes and intent of this Agreement including, without limitation, any filings with any government antitrust agency which may be required.
