(a) No person who is a member of the Board, a Trustee appointed under Section 22, or an officer or employee of the Authority, may be in any manner interested, either directly or indirectly, in his own name or in the name of any other person, partnership, association, trust or corporation, including any corporation subject to "The Medical Corporation Act", as now or hereafter amended, and any professional corporation organized under "The Professional Service Corporation Act", as now or hereafter amended, or organized under any similar law of a sister state applicable to any such corporation, in any contract or the performance of any work of the Authority. No such person may represent, either professionally or as agent or otherwise, any person, partnership, association, trust or corporation, including any corporation subject to "The Medical Corporation Act", as now or hereafter amended, and any professional corporation organized under "The Professional Service Corporation Act", as now or hereafter amended, or organized under any similar law of a sister state applicable to any such corporation, with respect to any application or bid for any contract or work in regard to which such person may be called upon to vote. Nor may any such person take or receive, or offer to take or receive, either directly or indirectly, any money or other thing of value as a gift or bribe or means of influencing his vote or action in his official character. Any contract made and procured in violation hereof is void. Each person who at any time within 2 years prior to the effective date of this amendatory Act of 1985 was a member of the Board and who at any time after so becoming a member ceased to be a member of the Board shall in all respects continue to be governed by and subject to the provisions of this subsection (a) for a period of 2 years from and after the date on which he last ceased or ceases to be a member of such Board. In addition, the provisions of this subsection (a) shall continue to apply equally and in all respects to each person who becomes a member of the Board on or after the effective date of this amendatory Act of 1985 and who thereafter ceases to be a member of the Board, and to any Trustee appointed under Section 22 who ceases to be the Trustee, for a period of 2 years from and after the date on which he ceases to be a member of the Board or to be the Trustee. The foregoing provisions of this subsection (a) shall not apply to render void or to interfere with the performance of any contract of the Authority entered into and in effect prior to the effective date of this amendatory Act of 1985. However any such person may provide materials, merchandise, property, services or labor, if:
(1) the contract is with a person, firm, partnership, association, corporation, or cooperative association in which such interested person has less than a 7 1/2% share in the ownership; and(2) such interested person publicly discloses the nature and extent of his interest prior to or during deliberations concerning the proposed award of the contract; and(3) such interested person, if a Board member, abstains from voting on the award of the contract, though he shall be considered present for the purposes of establishing a quorum; and(4) such contract is approved by a majority vote of those members presently holding office; and(5) the contract is awarded after sealed bids to the lowest responsible bidder if the amount of the contract exceeds $1500, or awarded without bidding if the amount of the contract is less than $1500; and(6) the award of the contract would not cause the aggregate amount of all such contracts so awarded to the same person, firm, association, partnership, corporation or cooperative association in the same fiscal year to exceed $25,000. In addition to the above exemption, any such person may provide materials, merchandise, property, services or labor if:
(1) the award of the contract is approved by a majority vote of the Board provided that any such interested member shall abstain from voting; and(2) the amount of the contract does not exceed $1000; and(3) the award of the contract would not cause the aggregate amount of all such contracts so awarded to the same person, firm, association, partnership, corporation or cooperative association in the same fiscal year to exceed $2000; and(4) such person publicly discloses the nature and extent of his interest prior to or during deliberations concerning the proposed award of the contract; and(5) such person abstains from voting on the award of the contract, though he shall be considered present for the purposes of establishing a quorum. A contract for the procurement of public utility services with a public utility company is not barred by this Section by any such person being an officer or employee of the public utility company or holding an ownership interest of no more than 7 1/2% in the public utility company. Any such person having such an interest shall be deemed not to have a prohibited interest under this Section.
