At least 10 days prior to the date set for hearing the Department shall, before refusing to issue or renew or before revocation of a registration, notify in writing the applicant for or holder of a registration, hereinafter called the respondent, that on the date designated a hearing will be held to determine whether the respondent is privileged to be registered, and shall afford the respondent an opportunity to be heard in person or by counsel. Such written notice shall be served personally on the respondent, or by registered or certified mail sent to the respondent's business address as shown in his latest notification to the Department. The Director shall, after a hearing, issue an order either issuing, renewing, refusing to issue or renew, reinstating, or revoking the license.
