ARTICLE 8

DISPUTE RESOLUTION

8.1                               Disputes.  The Parties recognize that disputes as to certain matters may from time to time arise during the Term which relate to either Party’s rights and/or obligations hereunder.  It is the objective of the Parties to establish under this ARTICLE 8 procedures to facilitate the resolution of disputes arising under this Agreement (other than any disputes relating to matters for which under the Other License Agreement Company or BeiGene has sole decision-making authority and/or discretion (each, a “Non-Escalable Dispute”), in which case, such matter shall be determined by Company or BeiGene, as the case may be, as set forth in the Other License Agreement and shall not be part of the dispute resolution procedure set forth in this ARTICLE 8) in an expedient manner by mutual cooperation and without resort to litigation.  In the event that the Parties are unable to resolve such dispute through diligent review and deliberation by the Senior Executives within thirty (30) days from the day that one Party had designated the issue as a dispute in written notice to the other Party, then either Party shall have the right to escalate such matter to the Executive Officers as set forth in Section 8.2.

8.2                               Escalation to Executive Officers.  Either Party may, by written notice to the other Party, request that a dispute (other than a Non-Escalable Dispute) that remains unresolved by the Senior Executives for a period of thirty (30) days as set forth in Section 8.1 arising between the Parties in connection with this Agreement, or a dispute relating to material breach, be resolved by the Executive Officers, within fifteen (15) days after referral of such dispute to them.  If the Executive Officers cannot resolve such dispute within fifteen (15) days after referral of such dispute to them, then, at any time after such fifteen (15) day period, either Party may proceed to enforce any and all of its rights with respect to such dispute.

8.3                               Arbitration.  If the Parties are unable to resolve the dispute following the procedure set forth in Section 8.2, then the dispute for arbitration shall be submitted in London, England in accordance with the Rules of Conciliation and Arbitration of the International Chamber of Commerce (the “ICC Rules”) then in effect.  Notwithstanding the foregoing, in all events, the provisions contained herein shall govern over any conflicting rules which may now or hereafter be contained in the ICC Rules.  Any judgment upon the award rendered by the panel of the arbitrators shall be entered in any court having jurisdiction over the subject matter thereof.  The panel of the

33

arbitrators shall have the authority to grant any equitable and legal remedies that would be available if any judicial proceeding was instituted to resolve said dispute.  The final decision of such panel of the arbitrators, as entered by a court of competent jurisdiction, will be furnished by such panel of the arbitrator in writing and will constitute a final, conclusive and non-appealable determination of the issue in question, binding upon the Parties, and an order with respect thereto may be entered in any court of competent jurisdiction.  Except as set forth in Section 8.4, the following procedures shall apply:

(a)                                 Each Party shall select one person to act as arbitrator and the two Party-selected arbitrators shall select a third arbitrator within ten (10) days of their appointment.  If the arbitrators selected by the Parties are unable or fail to agree upon the third arbitrator, the third arbitrator shall be appointed by the ICC.

(b)                                 No arbitrator shall have any past or present family, business or other relationship with the Parties or any Affiliate, director or officer thereof, unless following full disclosure of all such relationships, the Parties agree in writing to waive such requirement with respect to an individual in connection with any dispute.

(c)                                  No discovery other than an exchange of relevant documents may occur in any arbitration commenced under the provisions of this ARTICLE 8.  The Parties agree to act in good faith to promptly exchange relevant documents.

(d)                                 The Parties will each pay fifty percent (50%) of the initial compensation to be paid to the arbitrator in any such arbitration and fifty percent (50%) of the costs of transcripts and other normal and regular expenses of the arbitration proceedings; provided, however, that: (i) the prevailing Party in any arbitration will be entitled to an award of attorneys’ fees and costs; and (ii) all costs of arbitration, other than those provided for above, will be paid by the losing Party, and the arbitrator will be authorized to determine the identity of the prevailing Party and the losing Party.

(e)                                  The panel of the arbitrators chosen in accordance with these provisions will not have the power to alter, amend or otherwise affect the terms of these arbitration provisions or any other provisions contained in this Agreement.

34

8.4                               Injunctive Relief.  No provision herein shall be construed as precluding a Party from bringing an action for injunctive relief or other equitable relief prior to the initiation or completion of the above procedure.

ARTICLE 9

MISCELLANEOUS PROVISIONS

9.1                               Relationship of the Parties.  Nothing in this Agreement shall be construed or shall be deemed, for financial, tax, legal or other purposes (a) to create or imply a general partnership between the Parties, (b) to make either Party the agent of the other for any purpose, (c) to alter, amend, supersede or vitiate any other arrangements between the Parties with respect to any subject matters not covered hereunder, (d) to give either Party the right to bind the other, (e) to create any duties or obligations between the Parties except as expressly set forth herein, or (f) to grant any direct or implied licenses or any other right other than as expressly set forth herein.

proposals.  In making his or her selection, the arbitrator shall consider the terms and conditions of this Agreement, the relative merits of the final proposals, the prior investments made by the Company into the Collaboration Compound and Product and the written and oral arguments of the Parties.  In the event the arbitrator seeks the guidance of the law of any jurisdiction, the law of the England and Wales shall govern.
