If a member of the Authority or officer, agent or employee thereof holds such an interest then he or she shall refrain from any further official involvement in regard to such contract or agreement, from voting on any matter pertaining to such contract or agreement, and from communicating with other members of the Authority or its officers, agents and employees concerning said contract or agreement. Notwithstanding any other provision of law, any contract or agreement entered into in conformity with this subsection (b) shall not be void or invalid by reason of the interest described in this subsection, nor shall any person so disclosing the interest and refraining from further official involvement as provided in this subsection be guilty of an offense, be removed from office or be subject to any other penalty on account of such interest.(c) Any contract or agreement made in violation of paragraphs (a) or (b) of this Section shall be null and void and give rise to no action against the Authority. No real estate to which a member or employee of the Authority holds legal title or in which such person has any beneficial interest, including any interest in a land trust, shall be purchased by the Authority or by a nonprofit corporation or limited-profit entity for a development or any housing related commercial facilities to be financed under this Act. All members and employees of the Authority shall file annually with the Authority a record of all real estate in this State to which such person holds legal title or in which such person has any beneficial interest, including any interest in a land trust. In the event it is later disclosed that the Authority has purchased real estate in which a member or employee had an interest, such purchase shall be voidable by the Authority and the member or employee involved shall be disqualified from membership in or employment by the Authority.
