(1) The attorney-in-fact of every reciprocal transacting business in this State shall file with the Director a duly executed instrument whereby the attorney-in-fact shall appoint and constitute the Director and his successor or successors in office, the true and lawful attorney of such reciprocal upon whom all lawful process in any action or legal proceeding against such reciprocal may be served and shall agree that any lawful process against such reciprocal which may be served upon said attorney shall be of the same force and validity as if served upon the attorney-in-fact and that the authority thereof shall continue in force irrevocably so long as any liability of the reciprocal in the State shall remain outstanding.
     (2) Any reciprocal transacting business in this State may sue or be sued in the name or designation under which its contracts are authorized to be exchanged. Any such suit may be brought in the county in which the cause of action arises or in which the claimant resides, or in the county in which the attorney-in-fact has his principal office. Service may be had upon such reciprocal by service upon the last appointed attorney-in-fact or by service upon the Director. Service of process on an individual subscriber shall not constitute service upon the reciprocal. When such process is served upon the Director, duplicate copies of such process shall be delivered to him and he shall immediately forward one copy of such process to the last appointed attorney-in-fact, by certified or registered mail, postage prepaid, giving the date and hour of such service.
