The transaction of business in this State by such corporation and/or such consent by such corporation to the jurisdiction of any state or federal court in this State without provision for a manner of service of legal process shall be a signification of the agreement of such corporation that any process served upon the Secretary of State when so served shall be of the same legal force and validity as if served upon an authorized officer or agent personally within this State.

This section shall not apply to any insurance company doing business in this State.
