Shares in a professional corporation or a foreign professional corporation qualified to render professional services in this state may be transferred only to a licensed person, to a shareholder of the same corporation, to a person licensed to practice the same profession in the jurisdiction or jurisdictions in which the person practices, or to a professional corporation, and any transfer in violation of this restriction shall be void, except as provided herein.

A professional corporation may purchase its own shares without regard to any restrictions provided by law upon the repurchase of shares, if at least one share remains issued and outstanding.

If a professional corporation or a foreign professional corporation qualified to render professional services in this state shall fail to acquire all of the shares of a shareholder who is disqualified from rendering professional services in this state or of a deceased shareholder who was, on his or her date of death, licensed to render professional services in this state, or if such a disqualified shareholder or the representative of such a deceased shareholder shall fail to transfer said shares to the corporation, to another shareholder of the corporation, to a person licensed to practice the same profession in the jurisdiction or jurisdictions in which the person practices, or to a licensed person, within days following the date of disqualification, or within six months following the date of death of the shareholder, as the case may be, then the certificate of registration of the corporation may be suspended or revoked by the governmental agency regulating the profession in which the corporation is engaged.

In the event of such a suspension or revocation, the corporation shall cease to render professional services in this state. Notwithstanding any provision in this part, upon the death or incapacity of a dentist, any individual named in subdivision (
