It shall be unlawful for any beneficial owner, director, or officer, directly or indirectly, to sell any equity security of the company if the person selling the security or his or her principal: (1) does not own the security sold, or (2) if owning the security, does not deliver it against the sale within twenty (20) days thereafter, or does not within five (5) days after the sale deposit it in the mails or other usual channels of transportation. No person shall be deemed to have violated this section if he or she proves that notwithstanding the exercise of good faith he or she was unable to make the delivery or deposit within time, or that to do this would cause undue inconvenience or expense.
