(2) Failing any designation by the parties, the arbitral tribunal shall apply the law determined by the conflict of laws rules which it considers applicable.
(3) The arbitral tribunal shall decide ex aequo et bono or as amiable compositeur only if the parties have expressly authorized it to do so.
(4) In all cases, the arbitral tribunal shall decide in accordance with the terms of the contract and shall take into account the usages of the trade applicable to the transaction.
