(a) All bonds and securities issued by an authority shall be payable solely out of the revenues derived by the authority from the leasing, sale or operation of any or all of its projects as may be designated in the proceedings of its board under which the same shall be authorized to be issued. None of the bonds, securities or notes of an authority shall ever constitute an obligation or debt of the state, of any authorizing subdivision, or of any county or municipality of the state or a charge against the credit or taxing powers of any of them.
(b) Bonds of any authority may be executed and delivered by the authority at any time and from time to time, may be in such form and denominations and of such tenor and maturities, may be in registered or bearer form, either as to principal or interest or both, may be payable at such time or times not exceeding forty years from their date, may be made subject to redemption, may be payable at such place or places whether within or without the State of Alabama, may bear interest at such rate or rates (including variable rates), payable at such time or times and at such place or places and evidenced in such manner, and may contain such other provisions not inconsistent with this chapter, all as shall be provided in the proceedings of its board whereunder the bonds shall be authorized to be issued. Any bond having a stated maturity more than 10 years after its date shall state that it is subject to redemption at the option of the authority at the expiration of ten years from its date and on any interest payment date thereafter at such price or prices and after such notice or notices and on such terms and in such manner as may be provided in the proceedings wherein such bond is authorized to be issued.
(c) Any bonds of an authority may be sold at public or private sale in such manner and from time to time as may be determined by its board to be most advantageous and the authority may pay all expenses, premiums, fees and commissions that its board may deem necessary or advantageous in connection with the issuance thereof.
(d) The issuance by an authority of one or more series of bonds for one or more purposes shall not preclude it from issuing other bonds in connection with the same project or other projects, but the proceedings whereunder any subsequent bonds may be issued shall recognize and protect any prior assignment, lien or indenture for any prior issue of bonds unless in the proceedings authorizing such prior issue the right was reserved to issue subsequent bonds on a parity with such prior issue.
(e) All bonds shall contain a recital that they are issued pursuant to the provisions of this chapter, which recitals shall be conclusive that they have been duly authorized pursuant to the provisions of this chapter.
(f) All bonds issued hereunder and any interest coupons applicable thereto are hereby made and shall be construed to be negotiable instruments.
