(1) is required by statute to designate or maintain a resident agent or engages in business in this state, but has not designated or maintained a resident agent for service of process;
(2) has one or more resident agents for service of process, but two unsuccessful attempts have been made on different business days to serve each agent; or
(3) is not required to designate an agent for service in this state, but becomes a nonresident after a cause of action arises in this state but before the cause is matured by suit in a court of competent jurisdiction.
(b) The secretary of state is an agent for service of process on a nonresident who engages in business in this state, but does not maintain a regular place of business in this state or a designated agent for service of process, in any proceeding that arises out of the business done in this state and to which the nonresident is a party.
(c) After the death of a nonresident for whom the secretary of state is an agent for service of process under this section, the secretary of state is an agent for service of process on a nonresident administrator, executor, or personal representative of the nonresident.
