ARTICLE 16

DISPUTE RESOLUTION

16.1 Mandatory Procedures. The Parties agree that any dispute arising out of or relating to this Agreement shall be resolved solely by means of the procedures set forth in this Article 16, and that such procedures constitute legally binding obligations that are an essential provision of this Agreement. If either Party fails to observe the procedures of this Article 16, as may be modified by their written agreement, the other Party may bring an action for specific performance of these procedures in any court of competent jurisdiction. Notwithstanding the foregoing or anything in this Agreement, the provisions of this Article 16 as applied to Board and/or MDACC shall only apply to the extent authorized by the constitution and laws of the State of Texas, and shall not apply to Board or MDACC to the extent that such Party(ies) are not authorized to participate in the Dispute Resolution procedures of this Article 16 pursuant to the constitution and laws of the State of Texas.

16.2 Equitable Remedies. Although the procedures specified in this Article 16 are the sole and exclusive procedures for the resolution of disputes arising out of or relating to this Agreement, either Party may seek a preliminary injunction or other provisional equitable relief if, in its reasonable judgment, such action is necessary to avoid irreparable harm to itself or to preserve its rights under this Agreement.

16.3 Dispute Resolution Procedures. Any controversy or claim arising out of or relating to this Agreement, or the breach thereof, shall be settled by binding confidential arbitration in accordance with the Commercial Arbitration Rules of the American Arbitration Association (“AAA”), and the procedures set forth below. In the event of any inconsistency between the Rules of AAA and the procedures set forth below, the procedures set forth below shall control. Judgment upon the award rendered by the arbitrators may be enforced in any court having jurisdiction thereof.

(a) The arbitration shall be conducted by a panel of three neutral arbitrators who are independent and disinterested with respect to the Parties, this Agreement, and the outcome of the arbitration. Each Party shall appoint one neutral arbitrator, and these two arbitrators so selected by the Parties shall then select the third arbitrator, and all arbitrators must have at least ten (10) years’ experience in mediating or arbitrating cases regarding the same or substantially similar subject matter as the dispute between MDACC and Company. If one Party has given written notice to the other Party as to the identity of the arbitrator appointed by the Party, and the Party thereafter makes a written demand on the other Party to appoint its designated arbitrator within the next [***] days, and the other Party fails to appoint its designated arbitrator within [***] days after receiving said written demand, then the arbitrator who has already been designated shall appoint the other two arbitrators.

(b) The arbitrators shall decide any disputes and shall control the process concerning these pre-hearing discovery matters. Pursuant to the Rules of AAA, the Parties may subpoena witnesses and documents for presentation at the hearing.

(c) Prompt resolution of any dispute is important to the Parties; and the Parties agree that the arbitration of any dispute shall be conducted expeditiously. The arbitrators are instructed and directed to assume case management initiative and control over the arbitration process (including, without limitation, scheduling of events, pre-hearing discovery and activities, and the conduct of the hearing), in order to complete the arbitration as expeditiously as is reasonably practical for obtaining a just resolution of the dispute.

(d) The arbitrators may grant any legal or equitable remedy or relief that the arbitrators deem just and equitable, to the same extent that remedies or relief could be granted by a state

[***] Certain information in this document has been omitted from this exhibit because it is both (i) not material and (ii) would be competitively harmful if publicly disclosed.

or federal court, provided however, that no punitive damages may be awarded. No court action shall be maintained seeking punitive damages. The decision of any two (2) of the three (3) arbitrators appointed shall be binding upon the Parties. Notwithstanding anything to the contrary in this Agreement, prior to or while an arbitration proceeding is pending, either Party has the right to seek and obtain injunctive and other equitable relief from a court of competent jurisdiction to enforce that Party’s rights hereunder.

(e) The expenses of the arbitration, including, without limitation, the arbitrators’ fees, expert witness fees, and attorney’s fees, may be awarded to the prevailing Party, in the discretion of the arbitrators, or may be apportioned between the Parties in any manner deemed appropriate by the arbitrators. Unless and until the arbitrators decide that one Party is to pay for all (or a share) of such expenses, both Parties shall share equally in the payment of the arbitrators’ fees as and when billed by the arbitrators.

(f) Notwithstanding the foregoing, any disputes arising hereunder with respect to the inventorship, validity, enforceability or other aspect of intellectual property rights shall be resolved by a court of competent jurisdiction and not by arbitration.

(g) Except as set forth below and as necessary to obtain or enforce a judgment upon any arbitration award, the Parties shall keep confidential the fact of the arbitration, the dispute being arbitrated, and the decision of the arbitrators. Notwithstanding the foregoing, the Parties may disclose information about the arbitration to persons who have a need to know, such as directors, trustees, management employees, witnesses, experts, investors, attorneys, lenders, insurers, actual or potential collaborators or corporate partners of Company, actual or potential acquirors of Company, and others who may be directly affected provided that such persons are bound to keep such information confidential. Additionally, if a Party has stock which is publicly traded, the Party may make such disclosures as are required by applicable securities laws, but shall use commercially reasonably efforts to seek confidential treatment for such disclosure.

16.4 Performance to Continue. Each Party shall continue to perform its undisputed obligations under this Agreement pending final resolution of any dispute arising out of or relating to this Agreement; provided, however, that a Party may suspend performance of its undisputed obligations during any period in which the other Party fails or refuses to perform its undisputed obligations.

16.5 Statute of Limitations. The Parties agree that all applicable statutes of limitation and time-based defenses (such as estoppel and laches) shall be tolled while the procedures set forth in Article 16 are pending. The Parties shall cooperate in taking any actions necessary to achieve this result.
