If within ten days of the appointment of the second of them, the original two arbitrators are unable to agree upon a third arbitrator who will accept the appointment, either party may petition such a court of record of the State of Oregon for the appointment of a third arbitrator.

A copy of the award shall also be served at the same time upon the authorized officer or the State Director, either personally or by registered mail.(d) Costs of the arbitration proceedings shall be assessed by the arbitrators against either or both of the parties, as may appear equitable to the arbitrators, taking into account the original contentions of the parties, the ultimate decision of the arbitrators and such other matter as may appear relevant to the arbitrators.35 FR 9638, June 13, 1970, as amended at 41 FR 21642, May 27, 1976
