(b) Legal process shall be served upon the reciprocal insurer by serving the insurer's attorney at his principal office in this state or by serving the Commissioner as the insurer's agent.

(c) Any judgment based upon legal process served in the manner prescribed in subsection (b) of this Code section shall be binding upon each of the insurer's subscribers as their respective interests may appear but in an amount not exceeding their respective contingent liabilities, if any, as though personal service of process was had upon each subscriber.
