Rule 4.7 - Summons: Service upon agent named by statute or agreement Whenever an agent (other than an agent appointed to receive service for a governmental organization of this state) has been designated by or pursuant to statute or valid agreement to receive service for the person being served, service may be made upon such agent as follows:
(1) If the agent is a governmental organization or officer designated by or pursuant to statute, service shall be made as provided in Rule 4.10. (2) If the agent is one other than that described above, service shall be made upon him as provided in Rule 4.1 (service upon individuals) or 4.6 (service upon organizations). If service cannot be made upon such agent, because there is no address furnished as required by statute or valid agreement or his whereabouts in this state are unknown, then his principal shall be deemed to have appointed the Secretary of State as a replacement for the agent and service may be made upon the Secretary of State as provided in Rule 4.10.
