11.3 Dispute Resolution.

(a) Initiation. Both Parties shall endeavor to settle amicably and promptly any disputes, controversies and differences which may arise between the Parties out of or in relation to this Agreement or any breach thereof.

(b) Escalation. The Executive Officers shall, within [**] days after receipt of such notice, discuss, and attempt to resolve, the dispute. Neither Party may commence arbitration of any matter hereunder until the expiration of such [**] day period.

(c) Arbitration. Any dispute, controversy or claim arising out of or in connection with this Agreement, or breach, termination or invalidity thereof, that is not resolved by the procedure set forth in Section 11.3(b) shall be settled by arbitration in accordance with the commercial arbitration rules of the International Chamber of Commerce (“ICC”). The arbitral tribunal shall be composed of three arbitrators, one to be appointed by Durata and one to be appointed by RaQualia and the chairman to be appointed by the two arbitrators. If the two aforementioned Parties have not appointed their arbitrators within [**] weeks from the date on which arbitration was requested by either Party in writing, or the two arbitrators have not agreed on the chairman within [**] weeks after their appointment, the ICC shall appoint the arbitrator or the chairman, as the case may be.

The obligations under Sections 11.3(a), (b) and (c) shall not be binding upon any Party with respect to requests for preliminary injunctions, temporary restraining orders or other procedures in a court of competent jurisdiction to obtain interim relief when deemed necessary by such court to preserve the status quo or to prevent irreparable injury pending resolution by arbitration of the actual dispute.
