Unless otherwise provided by the agreement,
(1) the arbitrators shall set a time and place for the hearing and cause notification to the parties to be served personally or by registered mail not less than five days before the hearing; appearance at the hearing waives the notice; the arbitrators may adjourn the hearing from time to time as necessary and, on request of a party and for good cause or upon their own motion, may postpone the hearing to a time not later than the date fixed by the agreement for making the award unless the parties consent to a later date; the arbitrators may hear and determine the controversy upon the evidence produced notwithstanding the failure of a properly notified party to appear;
(2) the parties are entitled to be heard, to present evidence material to the controversy, and to cross-examine witnesses appearing at the hearing;
(3) the hearing shall be conducted by all the arbitrators but a majority may determine any question and render a final award; if, during the course of the hearing, an arbitrator for any reason ceases to act, the remaining arbitrator or arbitrators appointed to act as neutrals shall continue with the hearing and determination of the controversy.
