Borrowing money; revenue bonds; nature of indebtedness; investment in bonds. The Authority shall have continuing power to borrow money for the purpose of carrying out and performing its duties and exercising its powers under this Article.
     For the purpose of evidencing the obligation of the Authority to repay any money borrowed as aforesaid, the Authority may, pursuant to ordinance adopted by the Board, from time to time issue and dispose of its interest bearing revenue bonds, and may also from time to time issue and dispose of its interest bearing revenue bonds to refund any bonds at maturity or pursuant to redemption provisions or at any time before maturity with the consent of the holders thereof. All such bonds shall be payable solely from the revenues or income to be derived from the fairs, expositions, exhibitions, rentals and leases and other authorized activities operated by it, and from funds, if any, received and to be received by the Authority from any other source. Such bonds may bear such date or dates, may mature at such time or times not exceeding forty years from their respective dates, may bear interest at such rate or rates, not exceeding the maximum rate authorized by the Bond Authorization Act, as amended at the time of the making of the contract, payable semi-annually, may be in such form, may carry such registration privileges, may be executed in such manner, may be payable at such place or places, may be made subject to redemption in such manner and upon such terms, with or without premium as is stated on the face thereof, may be executed in such manner and may contain such terms and covenants, all as may be provided in said ordinance. In case any officer whose signature appears on any bond ceases (after attaching his signature) to hold office, his signature shall nevertheless be valid and effective for all purposes. The holder or holders of any bonds, or interest coupons appertaining thereto issued by the Authority may bring mandamus, injunction, or other civil actions or proceedings to compel the performance and observance by the Authority or any of its officers, agents or employees of any contract or covenant made by the Authority with the holders of such bonds or interest coupons, to compel the Authority and any of its officers, agents or employees to perform any duties required to be performed for the benefit of the holders of any such bonds or interest coupons by the provisions of the ordinance authorizing their issuance, and to enjoin the Authority and any of its officers, agents or employees from taking any action in conflict with any such contract or covenant.
     Notwithstanding the form and tenor of any such bonds and in the absence of any express recital on the face thereof that it is non-negotiable, all such bonds shall be negotiable instruments under the Uniform Commercial Code.
     The bonds shall be sold by the corporate authorities of the Authority in such manner as said corporate authorities shall determine except that if issued to bear interest at the maximum rate authorized by the Bond Authorization Act, as amended at the time of the making of the contract, the bonds shall be sold for not less than par and accrued interest and except that the selling price of bonds bearing interest at a rate of less than the maximum rate authorized by the Bond Authorization Act, as amended at the time of the making of the contract, shall be such that the interest cost to the Authority of the money received from the sale of bonds shall not exceed the maximum rate authorized by the Bond Authorization Act, as amended at the time of the making of the contract, computed to absolute maturity of said bonds or certificates according to standard tables of bond values.
     From and after the issuance of any bonds as herein provided it shall be the duty of the corporate authorities of the Authority to fix and establish rates, charges, rents, and fees for the use of its facilities sufficient at all times with other revenues of the Authority to pay:
     (a) the cost of maintaining, repairing, regulating and operating the said facilities; and
     (b) the bonds and interest thereon as they shall become due, and all sinking fund requirements and other requirements provided by the ordinance authorizing the issuance of the bonds or as provided by any trust agreement executed to secure payment thereof.
     To secure the payment of any or all of such bonds and for the purpose of setting forth the covenants and undertakings of the Authority in connection with the issuance thereof and the issuance of any additional bonds payable from such revenue income to be derived from the fairs, recreational, theatrical, cultural, expositions, sport activities, exhibitions, office rentals, and air space leases and rentals, and other revenue, if any, the Authority may execute and deliver a trust agreement or agreements; provided that no lien upon any physical property of the Authority shall be created thereby.
     A remedy for any breach or default of the terms of any such trust agreement by the Authority may be by mandamus, injunction, or other civil actions or proceedings in any court of competent jurisdiction to compel performance and compliance therewith, but the trust agreement may prescribe by whom or on whose behalf such action may be instituted.
     Under no circumstances shall any revenue bonds issued by the Authority be or become an indebtedness or obligation of the State of Illinois or of any other political subdivision of or municipality within the State, nor shall any such bond or obligation be or become an indebtedness of the Authority within the purview of any constitutional limitation or provision, and it shall be plainly stated on the face of each bond that it does not constitute such an indebtedness or obligation but is payable solely from the revenues or income as aforesaid.
     The State and all counties, cities, villages, incorporated towns and other municipal corporations; political subdivisions and public bodies, and public officers of any thereof, all banks, bankers, trust companies, savings banks and institutions, building and loan associations, savings and loan associations, investment companies and other persons carrying on an insurance business and all executors, administrators, guardians, trustees and other fiduciaries may legally invest any sinking funds, moneys or other funds belonging to them or within their control in any bonds issued pursuant to this Article, it being the purpose of this Section to authorize the investment in such bonds of all sinking, insurance, retirement, compensation, pension and trust funds, whether owned or controlled by private or public persons or officers; provided, however, that nothing contained in this Section may be construed as relieving any person from any duty of exercising reasonable care in selecting securities for investment.
     With respect to instruments for the payment of money issued under this Section either before, on, or after the effective date of Public Act 86-4, it is and always has been the intention of the General Assembly (i) that the Omnibus Bond Acts are and always have been supplementary grants of power to issue instruments in accordance with the Omnibus Bond Acts, regardless of any provision of this Article that may appear to be or to have been more restrictive than those Acts, (ii) that the provisions of this Section are not a limitation on the supplementary authority granted by the Omnibus Bond Acts, and (iii) that instruments issued under this Section within the supplementary authority granted by the Omnibus Bond Acts are not invalid because of any provision of this Article that may appear to be or to have been more restrictive than those Acts.
