Any amendment to the terms and conditions of this Agreement may only be implemented pursuant to Section 17.7 below.

3.5 Decision-Making.

3.5.1 Actions by Unanimous Vote. Subject to the terms of this Section 3.5, the JSC and the subcommittees will make decisions by unanimous vote with each Party having a single vote, irrespective of the number of representatives actually in attendance at a meeting, or by a written resolution signed by the designated representatives to the JSC or a subcommittee, as applicable, of each of the Parties. For the avoidance of doubt, the approval of all Development budgets and Marketing Budgets and any updates or amendments thereto by the JSC will require the unanimous vote with each Party having a single vote. The JSC members shall use good faith efforts to reach agreement on any and all matters submitted to the JSC. If the JSC fails to reach unanimous consent on a particular matter within thirty (30) days of a Party having requested a formal vote on such matter (or, if such matter is urgent, within seven (7) days of such request) or within thirty (30) days of referral of a matter from a subcommittee, then such dispute will be subject to the resolution procedures described in Sections 3.5.2 and 3.5.3.

3.5.2 Referral of Disputes for Resolution. If any subcommittee fails to reach unanimous agreement on a matter after it is presented for decision for a period in excess of thirty (30) days (or, if such matter is urgent, within seven (7) days of such request), the matter will be referred to the JSC. Unless the JSC decides to continue discussing the issue, the JSC will have meetings within thirty (30) days of receiving the dispute submission to reach unanimous consensus on a resolution.

(c) Disputes Over Non-Conforming Licensed Product. In the event that KHK disagrees with UGNX’s rejection because the Licensed Products are in fact conforming, the Parties shall cooperate to have both UGNX’s returned samples and KHK’s retained samples from the same production batch of the Licensed Products in dispute analyzed by a mutually acceptable independent testing laboratory of recognized reputation in the pharmaceutical industry,

using the analytical methods, tests and criteria for conformance set forth in the Specifications. The out-of-pocket external costs of such arrangement shall be shared [***] by the Parties, unless and until an alternative determination is made as provided below. The results of such laboratory testing shall be conclusive and binding on the Parties on the issue of compliance of such units of Licensed Product with the Specifications at the time of Delivery. If such independent testing laboratory determines that UGNX’s returned samples of such Licensed Product conform to the Specifications, then (i) the applicable Licensed Product shall be deemed to have been improperly rejected by UGNX, and (ii) UGNX shall bear the cost of the independent laboratory testing and all out-of-pocket external costs and expenses of returning the improperly rejected Licensed Product to UGNX. If such independent testing laboratory determines that UGNX’s returned samples of such Licensed Product did not conform to the Specifications and that such returned samples conform to the samples for such batch retained by KHK, then KHK shall bear the cost of the laboratory testing, as well as the costs associated with properly-rejected Licensed Product described in Section 8.2.7(b), and KHK shall promptly supply to UGNX conforming Licensed Products in accordance with Section 8.2.7(b).

(d) Sole Remedy. Except for Third Party Claims otherwise indemnified under this Agreement, the remedies expressly provided in this Section 8.2.7 will be UGNX’s sole and exclusive remedy for the breach of Section 8.2.6 as a result of the delivery by KHK of non-conforming Licensed Products.

(e) No Liability for Subsequent Events. In no event will KHK be liable under this Section 8.2.7 for Licensed Products that conformed to the Specifications at the time of Delivery but that ceased to so conform as a result of any event or occurrence, or any action or omission by UGNX, its Affiliate or a Third Party, following Delivery of such License Products.

14.2 Indemnity by KHK. KHK hereby agrees to defend, hold harmless and indemnify UGNX and its Affiliates agents, directors, officers and employees (the “UGNX Indemnitees”) from and against any and all Losses incurred by a UGNX Indemnitee in connection with any and all Third Party claims arising or resulting from (a) any misrepresentation (or alleged misrepresentation) or breach (or alleged breach) of any of the representations, warranties, covenants or agreements made by KHK under this Agreement other than such Losses arising from KHK’s failure to supply Licensed Products hereunder in conformance with the Specifications therefor and in compliance with Applicable Laws (including GMP) in the Profit Share Territory or the European Territory (provided that KHK shall not be responsible for complying with any additional requirements specifically applicable to Licensed Products for Development or Commercialization purposes in Latin America) where such failure could have been identified or detected by UGNX through its application of reasonable and customary quality assurance and quality control practices, or other inspections or activities required under such Applicable Laws with respect to such Licensed Products, prior to distribution of the Licensed Products in Latin America, and (only with respect to clinical supplies) in the Profit Share Territory or in the European Territory, as applicable; (b) any injury, damage or health complication suffered (or alleged to be suffered) as a result of the development, commercialization, use, promotion, marketing, distribution or sale of Licensed Product by or for KHK or its Affiliates or licensees in the Rest of the World or in the European Territory; (c) any violation by KHK or its Affiliates of laws and regulations applicable to Named Patient Sales in connection with any such Named Patient Sales made by KHK or its Affiliates under this Agreement in the European Territory, or (d) or UGNX’s reasonable and appropriate use of any Product Trademarks or KHK Trademarks in accordance with KHK’s instructions in connection with any Development or Commercialization of the Licensed Products in the Territory or in the European Territory, as applicable, except in the case of either (a) or (b), to the extent such Losses arise from UGNX’s breach of its representations, warranties or covenants.

14.3 Procedure for Indemnification. If a KFIK Indemnitee or UGNX Indemnitee (as the case may be, an “Indemnitee”) wishes to seek indemnification hereunder, such Indemnitee shall inform the Party obligated to indemnify the Indemnitee hereunder (the “Indemnifying Party”) of the Third Party claim giving rise to the obligation to indemnify as soon as reasonably practicable

after receiving Notice of such Third Party claim. The Indemnifying Party will have the right to assume and control the defense of any such Third Party claim for which it is obligated to indemnify the Indemnitee under this Agreement. The Indemnitee will cooperate with the Indemnifying Party (and its insurer) as the Indemnifying Party may reasonably request, and at the sole cost and expense of the Indemnifying Party. The Indemnitee will have the right to retain its own counsel, at the expense of the Indemnifying Party, if representation of such Indemnitee by the counsel retained by the Indemnifying Party would be inappropriate because of actual or potential differences in the interests of such Indemnitee and any other Party represented by such counsel. In all other cases, the Indemnitee will have the right to participate in such defense, subject to the Indemnifying Party’s control, using its own counsel at its own expense. The Indemnifying Party will have no obligation to indemnify any Indemnitee in connection with any settlement made without the Indemnifying Party’s prior written consent; provided that the Indemnifying Party does not unreasonably withhold or delay any such written consent. The Indemnifying Party shall seek the prior written consent of the Indemnitee for any settlement of a Third Party claim subject to indemnification hereunder (such consent to not be unreasonably withheld, delayed or conditioned) if such settlement would materially diminish or materially adversely affect the scope, exclusivity or duration of any intellectual property licensed under this Agreement, would require any payment by such Indemnitee, would require an admission of legal wrongdoing in any way on the part of an Indemnitee, or would affect an amendment of this Agreement (otherwise, no such consent shall be required). If the Indemnifying Party does not assume and conduct the defense of the Third Party claim as provided above, (a) the Indemnitee may defend against, and consent to the entry of any judgment or enter into any settlement with respect to the claim in any manner the Indemnitee may deem reasonably appropriate (and the Indemnitee need not consult with, or obtain any consent from, the Indemnifying Party in connection therewith), and (b) the Indemnifying Party will remain responsible to indemnify the Indemnitee as provided in this Article 14.

14.4 Losses for Product Liability Claims. Losses from any Third Party claim alleging product liability, product defect, design, packaging or labeling defect, failure to warn, or any similar action relating to the use or safety of a Licensed Product in the Field in any country of the world (each a “Product Liability Claim”) shall be allocated as follows:

(a) to the extent the Product Liability Claim is covered by a Party’s indemnity obligations under Sections 14.1 or 14.2, the Indemnifying Party shall [***];

(b) to the extent a Product Liability Claim is not covered by either Party’s indemnity obligations under Sections 14.1 or 14.2, then:

(i) For Product Liability Claims arising or resulting from Licensed Products sold in the Field in the Profit Share Territory, the Parties shall [***].

(ii) For Product Liability Claims arising or resulting from Licensed Product sold in the Field in the European Territory (except as set forth in Section 14.4(b)(i) above) and/or the Rest of the World, KHK shall [***]; and

(iii) For Product Liability Claims arising or resulting from Licensed Products sold in the Field in Latin America, UGNX shall [***].

14.5 Insurance. Each Party shall procure and maintain, at its sole cost and expense, comprehensive general liability insurance (which may be self insurance), including product liability insurance, with bodily injury, death and property limits and amounts of coverage consistent with industry standards, including contractual liability and product liability coverage. It is understood that such insurance will not be construed to create a limit of a Party’s liability with respect to its indemnification obligations hereunder. Each Party shall provide the other Party with written evidence of such insurance upon request.

If the Parties fail to resolve any Dispute pursuant to Section 16.1, either Party may submit that Dispute for final resolution by binding arbitration administered by the International Chamber of Commerce (“ICC”) in accordance with its Rules of Arbitration (the “Rules”) then in force, to the extent such Rules are not inconsistent with the provisions of this Agreement.

16.3 Number and Appointment of Arbitrators. Except as provided by this Section 16.3 or in Section 16.4, the appointment and confirmation of the arbitrators shall be made in accordance with the relevant provisions of the Rules. The arbitral tribunal shall be composed of three (3) arbitrators (the “Tribunal”) to be appointed in accordance with the Rules, except as expressly provided for herein. Each Party shall select one (1) arbitrator from the list of available ICC arbitrators and such arbitrators shall jointly appoint the third arbitrator who shall act as the chairman of the Tribunal (the “Chairman”). In the event any arbitrator becomes unable to serve, that arbitrator will be replaced in the same manner in which he or she was appointed. If either Party fails to appoint an arbitrator within [***] days of the initiation of arbitration, the other Party may request the ICC to appoint such co-arbitrator (for the non-responsive Party). Such appointment shall be binding on the Parties. If the arbitrators selected by the Parties cannot agree on a Chairman within [***] days after they have been selected, then the ICC shall appoint the Chairman upon request by either Party.

16.4 Special Rules For Certain Specific Disputes (Baseball Arbitration). This Section 16.4 shall only apply to the matters expressly identified in this Agreement as subject to resolution pursuant to this Section 16.4. The Tribunal for such matters shall be composed of one (1) arbitrator. In such arbitration, the arbitrator shall be an independent expert (including in the area of the dispute) in the pharmaceutical or biotechnology industry mutually acceptable to the Parties. The Parties shall use their best efforts to mutually agree upon one (1) arbitrator; provided, however, that if the Parties have not done so within [***] Business Days after initiation of arbitration hereunder, or such longer period of time as the Parties have agreed to in writing, then the ICC shall appoint such arbitrator (which arbitrator shall meet the requirements set forth in the preceding sentence) upon request by either Party. Arbitration pursuant to this Section 16.4 shall be limited to choosing one or the other from among the two proposed resolutions prepared by the two Parties with respect to all matters in dispute, and in connection therewith, each Party shall submit to the arbitrator and to each other in writing its position on and desired resolution of (including any specifics or breakdown of the amounts included within their respective figures) each such matter. Such submission shall be made within [***] Business Days of the selection or appointment of the arbitrator, and the arbitrator shall issue its resolution of all such matters within [***] days of receipt of the written submissions by both Parties. For the avoidance of doubt, the arbitrator’s resolution of all such matters shall be limited to the selection of one or the other of the two competing resolution methods proposed by the Parties and other than minor modification, the arbitrator may not impose a resolution not proposed by either Party or “split the difference” by creating a compromise resolution based on the desired resolutions proposed separately by the Parties. Except as provided in the preceding sentence, such arbitration shall be conducted in accordance with the relevant provisions of the ICC Rules. The arbitrator’s vote shall be final and binding upon the Parties.

16.5 Conduct of Arbitration. The arbitration shall be conducted and the award rendered in the English language.

16.6 Place of Arbitration. The arbitration shall be held in Singapore.

16.7 Powers of the Arbitrators, Limitations on Remedies. With respect to any arbitration conducted pursuant to Section 16.2, the Tribunal will have the power to award all remedies available under Applicable Laws, by a vote of at least two (2) of the three (3) arbitrators.

16.8 Arbitration Award. Except as set forth in Section 16.4 (Baseball Arbitration), the Tribunal will make all reasonable efforts to render a written, reasoned decision within [***] days following the closing of the hearing. The decision of the Tribunal will be final and binding on the Parties, and judgment upon the decision may be confirmed in, and judgment upon the award entered by, any court having jurisdiction over the Parties.

16.9 Confidentiality. Except to the extent necessary for proceedings relating to enforcement of the arbitration agreement, the award, or other related rights of the Parties, the fact of the arbitration, the arbitration proceeding itself, all evidence, written statements or other documents exchanged or used in the arbitration and the Tribunal’s award will be maintained in confidence by the Parties to the fullest extent permitted by law. However, a violation of this covenant will not affect the enforceability of this agreement to arbitrate or of the Tribunal’s award.

16.10 Costs. Each Party shall bear its own costs and expenses in connection with any Dispute resolution under this Article 16 and shall share equally (50/50) the fees, costs and expenses of the Tribunal and related Third Party arbitration expenses. Notwithstanding the foregoing, the prevailing Party may, as determined by the Tribunal under the circumstances, be awarded its attorneys’ fees, costs and expenses of the arbitration, including the arbitrators’ fees and expenses, in full. The Tribunal may also fix such costs and expenses proportionate to the extent each Party prevails in the arbitration, as the circumstances may warrant. If a Party fails to proceed with arbitration, unsuccessfully challenges the arbitration award or fails to comply with the arbitration award, the other Party will be entitled to costs, including reasonable attorneys’ fees and disbursements, for having to compel arbitration or defend or enforce the award.

16.11 Injunctive or Other Interim Relief. Notwithstanding the provisions of this Article 16, the Parties agree that irreparable harm might accrue with respect to a Dispute absent a temporary injunctive or other interim relief and the Parties therefore shall have the right to seek such injunctive or interim relief in a court of competent jurisdiction pending the outcome of Dispute resolution hereunder. In the event interim or injunctive relief is sought by a Party as to a Dispute, and a court of competent jurisdiction grants such interim or injunctive relief, the Parties shall continue to be bound under this Article 16 to resolve by arbitration such Dispute that is the subject of interim or injunctive relief.

16.12 Continued Performance. Pending resolution of any Dispute covered by this Article 16, both Parties shall continue their performance under this Agreement of any obligations (including payment obligations) that are not the subject of such Dispute.

16.13 Governing Law. Resolution of all Disputes arising out of or related to this Agreement or the performance, enforcement, breach or termination of this Agreement and any remedies relating thereto, will be governed by and construed under the substantive laws of the State of New York, U.S.A., without reference to any choice of law principles thereof that would cause the application of the laws of a different jurisdiction.

16.14 Separability and Survival of the Agreement to Arbitrate. The provisions of this agreement to arbitrate are independent of the remaining provisions of this Agreement and the Parties intend that the remaining provisions shall continue in effect even though one or more of the provisions of the Agreement will be determined to be null and void. This agreement to arbitrate will also survive the termination or expiration of this Agreement.

ARTICLE 17.

OTHER PROVISIONS

17.1 Non-Solicitation of Employees. During the Term, neither Party nor its Affiliates shall, directly or through its representatives or agents, solicit for employment or hire any officer, director, or employee of the other Party or its Affiliates with whom it has had contact in connection with, or who otherwise is known by it to participate in, the subject matter of this Agreement or the development of the Drug Substance or a Licensed Product; provided, however, a Party will not be prohibited from soliciting and hiring through general public advertisement or other solicitation that is not directed toward the employees of the other Party, and a Party may hire any former employee of the other Party as long as the discussions with the former employee are initiated after termination of employment by the other Party.

17.2 Force Majeure. Both Parties will be excused from the performance of their obligations under this Agreement, other than the obligation to make monetary payments, and neither Party will be held liable or responsible to the other Party nor be deemed to have defaulted under or breached this Agreement for failure or delay in fulfilling or performing any term of this Agreement, to the extent that such performance is prevented by force majeure and the nonperforming Party promptly provides Notice thereof to the other Party. Such excuse will be continued so long as the condition constituting a force majeure event continues and the nonperforming Party uses Commercially Reasonable Efforts to remove the condition. For purposes of this Agreement, a force majeure event (“Force Majeure Event”) will include conditions beyond the reasonable control and without the fault of a Party, such as an act of God, voluntary or involuntary compliance with any regulation, law or order of any government, war, an act of terrorism, civil commotion, labor strike or lock-out, epidemic, failure or default of public utilities or common carriers, destruction of production facilities or materials by fire, earthquake, storm or like catastrophe, inability to procure necessary raw materials in a commercially reasonable manner or default of suppliers or sub-contractors; provided, however, the payment of invoices due and owing hereunder may not be delayed by the payer because of a force majeure affecting the payer.

17.3 Exclusions of Consequential Damages. EXCEPT IN THE CASE OF A PARTY’S INTENTIONAL OR WILLFUL MISCONDUCT OR EGREGIOUS BAD FAITH CONDUCT OR DAMAGES AWARDED TO THIRD PARTIES COVERED BY THE INDEMNITY OBLIGATIONS SET FORTH IN SECTION 14, IN NO EVENT WILL EITHER PARTY BE LIABLE TO THE OTHER PARTY FOR LOST PROFITS OR FOR ANY INDIRECT, INCIDENTAL, CONSEQUENTIAL, SPECIAL, PUNITIVE OR EXEMPLARY DAMAGES OF THE OTHER PARTY IN CONNECTION WITH THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT, HOWEVER CAUSED, UNDER ANY THEORY OF LIABILITY, AND WHETHER OR NOT SUCH PARTY HAD PRIOR NOTICE THEREOF.

17.4 Assignment. Neither Party may assign this Agreement or any of its obligations hereunder without the prior written consent of the other Party; provided, however, that either Party may assign this Agreement in its entirety without such consent to any of its Affiliates, to any purchaser of all, or substantially all, of its assets or to any successor corporation resulting from any merger, consolidation, share exchange, or other similar transaction, and provided further that either Party may assign or sell its rights to receive any amounts due hereunder. This Agreement will inure to the benefit of UGNX and IGIK and their respective successors and permitted assigns. Any assignment of this Agreement that is not made in accordance with this Section 17.4 shall be null and void and of no legal force or effect.

17.5 Severability. In the event any one or more of the provisions contained in this Agreement should be held invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein will not in any way be affected or impaired thereby, unless the absence of the invalidated provision(s) frustrates the purpose of this Agreement (in which case the Parties will attempt to replace such invalidated provision with an enforceable provision that most clearly implements such purpose). The Parties will in such an instance use their Commercially Reasonable Efforts to replace the invalid, illegal or unenforceable provision(s) with valid, legal and enforceable provision(s) that, insofar as practical, implement the purposes of this Agreement.

17.6 Notices. All notices, consents, approvals and other legally operative communications that are required or permitted hereunder (“Notice”) will be in writing in the English language and sufficient if delivered personally, sent by facsimile or e-mail (and promptly confirmed by personal delivery, registered or certified mail or overnight courier), sent by nationally-recognized overnight courier or sent by registered or certified mail, postage prepaid, return receipt requested, addressed as follows:

17.11 Waiver. The waiver by either Party hereto of any right hereunder or the failure to perform or of a breach by the other Party will not be deemed a waiver of any other right hereunder or of any other breach or failure by said other Party whether of a similar nature or otherwise.

17.12 Counterparts. This Agreement may be executed in identical duplicate copies exchanged by facsimile or e-mail (PDF form) transmission.

17.13 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.
