ARTICLE 15

DISPUTE RESOLUTION

15.1 Internal Resolution. Corvus and Genentech recognize that a dispute, controversy or claim of any nature whatsoever arising out of or relating to this Agreement (each, a “Dispute”) may from time to time arise during the Term. In the event of the occurrence of such a Dispute, the Parties shall first refer such Dispute to the JDC pursuant to Section 3.1(c). If the JDC cannot resolve such Dispute, the Party bringing the Dispute shall provide written notice, including a description of the Dispute and the steps taken to resolve such Dispute, to the other Party. Upon receipt of such notice, the Dispute shall be referred to [***] and [***] for resolution, prior to proceeding under the other provisions of Article 15. In the event that such Dispute is not resolved within [***] of such other Party’s receipt of such notice, [***]. For all other Disputes not subject to final decision making authority of a Party, either Party may commence an arbitration to resolve such Dispute in accordance with Section 15.2.

15.2 Arbitration. Except as otherwise expressly provided in this Agreement, the Parties agree that any Dispute not resolved internally by the Parties pursuant to Section 15.1 shall be resolved through binding arbitration conducted by the American Arbitration Association in accordance with the then prevailing Commercial Arbitration Rules of the American Arbitration Association (for purposes of Article 15, the “Rules”), except as modified in this Agreement, applying the substantive law specified in Section 16.2.

(a) Arbitrators; Location. Each Party shall select one (1) arbitrator, and the two (2) arbitrators so selected shall choose a third arbitrator. All three (3) arbitrators shall serve as neutrals and have at least ten (10) years of both (i) dispute resolution experience (which may include judicial experience) and (ii) legal or business experience in the biotech or pharmaceutical industry. If a Party fails to nominate its arbitrator, or if the Parties’ arbitrators cannot agree on

the third arbitrator, the necessary appointments shall be made in accordance with the Rules. Once appointed by a Party, such Party shall have no ex parte communication with its appointed arbitrator. The arbitration proceedings shall be conducted in [***].

(b) Procedures; Awards. Each Party agrees to use reasonable efforts to make all of its then current employees available, if reasonably needed, and agrees that the arbitrators may deem any employee or person as necessary to the arbitration. The arbitrators shall be instructed and required to render a written, binding, non-appealable resolution and award on each issue that clearly states the basis upon which such resolution and award is made. The written resolution and award shall be delivered to the Parties as expeditiously as possible, but in no event more than ninety (90) days after conclusion of the hearing, unless otherwise agreed by the Parties. Judgment upon such award may be entered in any competent court or application may be made to any competent court for judicial acceptance of such an award and order for enforcement. Each Party agrees that, notwithstanding any provision of applicable law or of this Agreement, it will not request, and the arbitrators shall have no authority to award punitive or exemplary damages against any Party.

(c) Interim Equitable Relief. Notwithstanding anything to the contrary in Article 15, in the event that a Party reasonably requires relief on a more expedited basis than would be possible pursuant to the procedure set forth in Article 15, such Party may seek a temporary injunction or other interim equitable relief in a court of competent jurisdiction pending the opportunity of the arbitrators to review the decision under Article 15. Such court shall have no jurisdiction or ability to resolve disputes beyond the specific issue of temporary injunction or other interim equitable relief.

(d) Protective Orders; Arbitrability. At the request of either Party, the arbitrators shall enter an appropriate protective order to maintain the confidentiality of information produced or exchanged in the course of the arbitration proceedings. The arbitrators shall have the power to decide all questions of arbitrability.

15.3 Subject Matter Exclusions. Notwithstanding the provisions of Section 15.2, any Dispute not resolved internally by the Parties pursuant to Section 15.1 that involves the scope, enforceability, validity or infringement of any Corvus Patent, Genentech Patent or Joint Patent (a) that is issued in the United States shall be subject to actions before the United States Patent and Trademark Office and/or submitted exclusively to the federal court located in the jurisdiction of the district where any of the defendants resides; and (b) that is issued in any other country shall be brought before an appropriate regulatory or administrative body or court in that country, and the Parties hereby consent to the jurisdiction and venue of such courts and bodies.
