	15.2.2	Prior to commencing arbitration, the Parties may, if they so agree, seek the opinion of the relevant manufacturer in relation to the Services under dispute with a view to settling the dispute in good faith. In addition,
each Party shall appoint a designated representative whose task it will be to meet for the purpose of endeavouring to resolve such dispute. The designated representatives shall discuss the problem and negotiate in good faith in an effort to resolve
the dispute without the necessity of any formal proceeding. These procedures shall not prejudice either Party’s right to commence arbitration at any time as per Article 15.2.3. 

 

	15.2.3	If the dispute is not resolved by the Parties under Section 15.2.2, it shall be finally settled under the Rules of Arbitration of the International Chamber of Commerce by three (3) arbitrators appointed in

Party’s success. 

  

	15.2.5	The award of the arbitration may be enforced in any court having jurisdiction over the person or property of the Parties. Nothing in this Agreement shall prevent any Party, before an arbitration has commenced pursuant
to this Article 15.2, from seeking interim or injunctive relief, which will then have to be approved by the arbitral tribunal as per Article 15.2.3. For the sole and exclusive purpose of seeking pre-arbitral interim or injunctive relief, both
Parties hereby consent and submit to the sole and exclusive jurisdiction of the federal courts of the Southern District of New York, and agree that such court is the most appropriate and convenient court to settle any pre-arbitral dispute, and
accordingly waive the right to argue the contrary.
