Where deemed necessary by the licensing authority for any profession in order to prevent violations of the ethical standards of such profession, the licensing authority may by rule further restrict, condition or abridge the authority of a professional corporation to issue shares, but no such rule shall, of itself, have the effect of causing a shareholder of a professional corporation at the time such rule becomes effective to become a disqualified person. All shares issued in violation of this section or any rule adopted under this section shall be void.  3. A shareholder of a professional corporation may transfer or pledge shares, fractional shares and rights or options to purchase shares of the corporation only to natural persons, general partnerships, trustees, in trust, of certain revocable trust agreements as described in subdivision (1) of subsection 1 of this section, and professional corporations or foreign professional corporations qualified under sections 356.011 to 356.261 to hold shares issued directly to them by such professional corporation. Any transfer of shares in violation of this subsection shall be void; except that, nothing contained in this subsection shall prohibit the transfer of shares of a professional corporation by operation of law or court decree.  4. Every certificate representing shares of stock of a professional corporation shall state conspicuously upon its face that the shares represented thereby are subject to restrictions on transfer imposed by sections 356.011 to 356.261 and are subject to such further restrictions on transfer as may be imposed from time to time pursuant to sections 356.011 to 356.261 by any licensing authority governing the practice of a professional service permitted by the articles of incorporation of the corporation. ­­-------- (L. 1986 H.B. 1230, A.L. 1991 H.B. 219, A.L. 1993 S.B. 66 & 20)  Effective 12-01-93
