Every applicant for registration under this chapter, federal covered adviser, and every issuer which proposes to offer a security in this State through any person acting on any agency basis in the common-law sense shall file with the securities commissioner, in such form as he by rule prescribes, an irrevocable consent appointing the securities commissioner or his successor in office to be his attorney to receive service of any lawful process in any noncriminal suit, action, or proceeding against him or his successor, executor, or administrator which arises under this chapter or any rule or order hereunder after the consent has been filed, with the same force and validity as if served personally on the person filing the consent. A person who has filed such a consent in connection with a previous registration need not file another. Service may be made by leaving a copy of the process in the office of the securities commissioner, but it is not effective unless (a) the plaintiff, who may be the securities commissioner in a suit, action, or proceeding instituted by him, forthwith sends notice of the service and a copy of the process by registered mail to the defendant or respondent at his last address on file with the securities commissioner and (b) the plaintiff's affidavit of compliance with this section is filed in the case on or before the return day of the process, if any, or within such further time as the court allows.
