(a) The units may agree that any joint agency established under G.S. 160A‑462 shall appoint the officers, agents, and employees necessary to execute the undertaking, or that the units jointly shall appoint these personnel, or that one of the units shall appoint the personnel with their services contracted for by the other units or by the joint agency. If the units determine that one unit shall appoint the personnel, the agreement shall provide that the jurisdiction, authority, rights, privileges, and immunities (including coverage under the workers' compensation laws) which the officers, agents, and employees of the appointing unit enjoy within the territory of that unit shall also be enjoyed by them outside its territory when they are acting pursuant to the agreement and within the scope of their authority or the course of their employment.
(b) When the subject of an undertaking is a sovereign function of government, the exercise of which has been delegated to an officer of each participating unit, the agreement may provide that one officer shall exercise the function for all the participating units, with all of the powers, duties, and obligations that an officer exercising the function in a single unit would have.
