Article 14
DISPUTE RESOLUTION

14.1Disputes. 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 procedures to facilitate the resolution of disputes arising under this Agreement in an expedient manner by mutual cooperation and without resort to litigation. To accomplish this objective, the Parties agree to follow the procedures set forth in this Article 14 to resolve any controversy or claim arising out of, relating to, or in connection with any provision of this Agreement, if and when a dispute arises under this Agreement.

14.2Internal Resolution. With respect to all disputes arising between the Parties under this Agreement, including, without limitation, any alleged breach under this Agreement or any issue relating to the interpretation or application of this Agreement, if the Parties are unable to resolve such dispute within [*] after such dispute is first identified by either Party in writing to the other, the Parties shall refer such dispute to the Executive Officers of the Parties for attempted resolution by good faith negotiations within [*] after such notice is received.

14.3Binding Arbitration.

(a)If the Parties fail to resolve the dispute through escalation to the Executive Officers under Section 14.2, and a Party desires to pursue resolution of the dispute, the dispute shall be submitted by either Party for resolution in arbitration administered by the International Chamber of Commerce (“ICC”) pursuant to its arbitration rules and procedures then in effect.

(b)The arbitration shall be conducted by a panel of three arbitrators experienced in the pharmaceutical business. Within [*] after initiation of arbitration, each Party shall select one person to act as arbitrator and the two Party-selected arbitrators shall select a third arbitrator (who shall be the chairperson of the arbitration panel) within [*] 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 ICC. If, however, the aggregate award sought by the Parties is less than [*] and equitable relief is not sought, the arbitration shall be conducted by a single arbitrator agreed by the Parties (or appointed by ICC if the Parties cannot agree).

(c)The seat and location of the arbitration shall be [*], and the language of the proceedings shall be English. The arbitral tribunal shall determine the dispute by applying the provisions of this Agreement and the governing law set forth in Section 15.6. The Parties agree that any award or decision made by the arbitral tribunal shall be final and binding upon them and may be enforced in the same manner as a judgment or order of a court of competent jurisdiction.

(d)By agreeing to arbitration, the Parties do not intend to deprive any court of its jurisdiction to issue, at the request of a Party, a pre-arbitral injunction, pre-arbitral attachment or other order to avoid irreparable harm, maintain the status quo, preserve the subject matter of the dispute, or aid the arbitration proceedings and the enforcement of any award. Without prejudice to such provisional or interim remedies in aid of arbitration as may be available under the jurisdiction of a competent court, the arbitral tribunal shall have full authority to grant provisional or interim remedies and to award damages for the failure of any Party to the dispute to respect the arbitral tribunal’s order to that effect.

(e)Each Party shall bear its own attorney’s fees, costs, and disbursements arising out of the arbitration, and shall pay an equal share of the fees and costs of the administrator and the arbitrator; provided, however, the arbitrator shall be authorized to determine whether a Party is the prevailing party, and if so, to award to that prevailing party reimbursement for any or all of its reasonable attorneys’ fees, costs and disbursements (including, for example, expert witness fees and expenses, travel expenses, etc.), and/or the fees and costs of the administrator and the arbitrator.

(f)Notwithstanding anything in this Section 14.3, in the event of a dispute with respect to the validity, scope, enforceability or ownership of any Patent or other intellectual property rights, and such dispute is not resolved in accordance with Section 14.2, such dispute shall not be submitted to an arbitration proceeding in accordance with this Section 14.3, unless otherwise agreed by the Parties in writing, and instead either Party may initiate litigation in a court of competent jurisdiction in any country in which such rights apply.

- Ji Xing Pharmaceuticals to develop and commercialize etripamil for patients with PSVT in Greater China -

- Milestone to receive a $15 million upfront cash payment and a $5 million equity investment by RTW Investments, LP -

Montreal and Charlotte, N.C., May 17, 2021 -- Milestone Pharmaceuticals Inc. (Nasdaq: MIST), a biopharmaceutical company focused on the development and commercialization of innovative cardiovascular medicines, today announced an exclusive license and collaboration agreement with Ji Xing Pharmaceuticals (Ji Xing) to develop and, if approved, commercialize the investigational drug etripamil in patients with paroxysmal supraventricular tachycardia (PSVT) and additional cardiovascular conditions in Greater China. Ji Xing is a biotechnology company headquartered in Shanghai and backed by RTW Investments, LP (RTW) focused on advancing innovative medicines in China.

“This agreement marks an important step toward realizing our vision for etripamil to benefit patients living with PSVT globally while strengthening our balance sheet and executional capabilities through partnership,” said Joseph Oliveto, President and Chief Executive Officer of Milestone Pharmaceuticals. “We look forward to partnering with the talented team at Ji Xing to develop and commercialize this promising therapy in the licensed regions.”

“Etripamil has the potential to change the treatment paradigm for PSVT and could serve as a meaningful new therapeutic option for patients,” said Peter Fong, Chief Executive Officer of Ji Xing and Head of Company Creation at RTW. “We are delighted to expand Ji Xing’s cardiovascular focus by partnering with Milestone and look forward to unlocking the full therapeutic potential of etripamil for patients with PSVT in China.”

Under the terms of the agreement, Milestone will grant Ji Xing an exclusive license to develop and, if regulatory approval is obtained, commercialize etripamil in patients with PSVT in Greater China. Milestone will receive an upfront cash payment consisting of $15 million and a $5 million equity investment by RTW. In addition, Milestone is eligible to receive up to $107.5 million in milestone payments and royalties on future sales of etripamil in Greater China. Milestone will supply etripamil and delivery devices to Ji Xing. Ji Xing will be responsible for development and commercialization costs in Greater China.

About Paroxysmal Supraventricular Tachycardia

Paroxysmal supraventricular tachycardia (PSVT) is a rapid heart rate condition characterized by intermittent episodes of supraventricular tachycardia (SVT) that start and stop suddenly and without warning that affects approximately two million Americans. Episodes of SVT are often associated with symptoms including palpitations, sweating, chest pressure or pain, shortness of breath, sudden onset of fatigue, lightheadedness or dizziness, fainting, and anxiety. Certain calcium channel blockers have long been approved for the treatment of PSVT as well as other cardiac conditions. However, calcium channel blockers approved for the

termination of SVT episodes must be administered intravenously under medical supervision, usually in an emergency department or other acute care setting.

About Etripamil

Etripamil, Milestone's lead investigational product, is a novel calcium channel blocker designed to be a rapid-response therapy for episodic cardiovascular conditions. As a nasal spray that is self-administered by the patient, etripamil has the potential to shift the current treatment experience for many patients from the emergency department to the at-home setting. Milestone is conducting a comprehensive development program for etripamil, with Phase 3 trials ongoing in paroxysmal supraventricular tachycardia (PSVT) and a Phase 2 proof-of-concept trial is now underway in patients with atrial fibrillation and rapid ventricular rate (AFib-RVR).

About Ji Xing Pharmaceuticals

Backed by RTW Investments, LP, Ji Xing is a privately held, leading biotechnology company headquartered in Shanghai committed to bringing innovative science and medicines to underserved Chinese patients with serious and life-threatening diseases.
