The authority shall have power and is hereby authorized from time to time to provide by resolution for the issuance of negotiable revenue bonds for the purpose of paying all or any part of the cost as herein defined of any of its projects. Such bonds may also be issued to pay off, refund or refinance any outstanding bonds or other obligation of any nature owed by the authority, whether or not such revenue bonds or other obligations shall then be subject to redemption, and the authority may provide for such arrangements as it may determine for the payment and security of the revenue bonds being issued or for the payment and security of the revenue bonds or other obligations to be paid off, refunded or refinanced. The principal, premium, if any, and interest of such revenue bonds shall be payable solely from the revenues, receipts and earnings to be received by the authority in connection with the lease, sale, financing arrangement or other disposition of the project for which the revenue bonds were issued. All revenue bonds issued by the authority are hereby declared to be negotiable for all purposes notwithstanding their payment from a limited source and without regard to any other law or laws. The authority may limit the negotiability of its obligations by issuing the same in nonnegotiable or registered form or by providing for future registration under such terms and conditions as it may choose. All bonds issued by the authority shall be signed by the chairman of the authority and attested by its secretary, and the seal of the authority shall be affixed thereto and any interest coupons applicable to the bonds of the authority shall be signed by the chairman of the authority; provided, that a facsimile signature of one, but not both, of said officers may be printed or otherwise reproduced on any such bonds in lieu of his manually signing the same, and a facsimile of the signature of the chairman of the authority may be printed or otherwise reproduced on any such interest coupons in lieu of his manually signing the same. Any such bonds may be executed and delivered by the authority at any time and from time to time, shall be in such form and denominations and of such tenor and maturities, shall contain such provisions not inconsistent with the provisions of this chapter and shall bear such rate or rates of interest, payable and evidenced in such manner as may be provided by resolution of the authority. Bonds of the authority may be sold at either public or private sale in such manner and at such price or prices and at such time or times as may be determined by the authority to be most advantageous. The principal of or interest on any bonds issued or obligations assumed by the authority may thereafter at any time (whether before, at or after maturity of any such principal and whether at, after or not exceeding six months prior to the maturity of any such interest) and from time to time be refunded by the issuance of refunding bonds of the authority, which may be sold by the authority at public or private sale at such price or prices as may be determined by the authority to be most advantageous or which may be exchanged from the bonds or other obligations to be refunded. The authority may pay all expenses, premiums and commissions which it may deem necessary and advantageous in connection with any financing done by it. All bonds issued by the authority shall be construed to be negotiable instruments though payable from a specified source. All obligations created or assumed by the authority shall be solely and exclusively an obligation of the authority and shall not create an obligation or debt of any county or municipality or of the state; provided, that the provisions of this sentence shall not be construed to release the original obligor from liability on any bond or other obligation assumed by the authority. Any bonds issued by the authority shall be limited or special obligations of the authority payable solely out of the revenues of the authority specified in the proceedings authorizing those bonds. Any such proceedings may provide that the bonds therein authorized shall be payable solely out of the revenues derived from the operation of all property and facilities, owned or operated by the authority or solely out of the revenues from the operation of any one or more of such property and facilities, or parts thereof, regardless of the fact that those bonds may have been issued with respect to or for the benefit of only certain particular property and facilities of the authority. The authority may pledge for the payment of any of its bonds issued or obligations assumed the revenues from which such bonds or obligations are payable and may execute and deliver a trust indenture evidencing any such pledge or a mortgage and deed of trust conveying as security for such bonds or obligations the property and facilities, or any part of any thereof, the revenues or any part of the revenues from which are so pledged. Any mortgage and deed of trust or trust indenture made by the authority may contain such agreements as the authority may deem advisable respecting the operation and maintenance of the property and the use of the revenues subject to such mortgage and deed of trust or affected by such trust indenture and respecting the rights, duties and remedies of the parties to any such instrument and the parties for the benefit of whom such instrument is made; provided, that no such instrument shall be subject to foreclosure.
