It shall be unlawful for any beneficial owner of an insurer, or director or officer thereof, described in Section 1104.2, to, directly or indirectly, sell any stock of such insurer if he or his principal does not own the stock sold, or, if he or his principal owns the stock, he does not deliver it against such sale within 20 days thereafter, or does not within five days after such sale deposit it in the mails or other usual channels of transportation; but no person shall be deemed to have violated this section if he proves that notwithstanding the exercise of good faith he was unable to make such delivery or deposit within such time, or that to do so would cause undue inconvenience or expense.
