1. Where parties have agreed that disputes between them in respect of a defined legal relationship, whether contractual or not, shall be referred to arbitration under the UNCITRAL Arbitration Rules, then such disputes shall be settled in accordance with these Rules subject to such modification as the parties may agree.

2. The parties to an arbitration agreement concluded after 15 August 2010 shall be presumed to have referred to the Rules in effect on the date of commencement of the arbitration, unless the parties have agreed to apply a particular version of the Rules. That presumption does not apply where the arbitration agree- ment has been concluded by accepting after 15 August 2010 an offer made before that date.

3. These Rules shall govern the arbitration except that where any of these Rules is in conflict with a provision of the law applicable to the arbitration from which the parties cannot derogate, that provision shall prevail.
