Okla. Stat. tit. 11, § 11-51-107: Arbitrators - Selection

Within five (5) days from the date of the request for

arbitration referred to in Section 51-106 of this title, the

bargaining agent and the corporate authorities shall each select and

name one arbitrator and shall immediately thereafter notify each

other in writing of the name and address of the person so selected.

The two arbitrators so selected and named shall, within five (5)

days from and after the expiration of the five-day period

hereinabove mentioned, agree upon and select a third arbitrator. If,

on the expiration of the period allowed therefor, the arbitrators

are unable to agree upon the selection of a third arbitrator, the

bargaining agent and the corporate authorities shall request the

Federal Mediation and Conciliation Service to provide a list of five

arbitrators. Within five (5) days after receipt of the list of

arbitrators from the Federal Mediation and Conciliation Service, the

two arbitrators already selected shall alternately strike the name

of one arbitrator from the list of five until one name remains, with

the employer making the first strike from said list. The third

arbitrator, whether selected as a result of an agreement between the

two arbitrators previously selected or selected from the list

provided by the Federal Mediation and Conciliation Service, shall

act as chairman of the arbitration board.
