All bonds issued by the corporation shall be payable solely out of the revenues and receipts derived from the leasing or sale by the corporation of its projects or of any thereof as may be designated in the proceedings of the board of directors under which the bonds shall be authorized to be issued.
Such bonds may be executed and delivered by the corporation 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 40 years from the date thereof, may be payable at such place or places whether within or without the State of Alabama, may bear interest at such rate or rates payable at such time or times and at such place or places and evidence in such manner, may be executed by such officers of the corporation and in such manner and may contain such provisions not inconsistent with this article, all as shall be provided in the proceedings of the board of directors whereunder the bonds shall be authorized to be issued. If deemed advisable by the board of directors, there may be retained in the proceedings under which any bonds of the corporation are authorized to be issued an option to redeem all or any part thereof as may be specified in such proceedings at such price or prices and after such notice or notices and on such terms and conditions as may be set forth in such proceedings and as may be briefly recited in the face of the bonds, but nothing contained in this section shall be construed to confer on the corporation any right or option to redeem any bonds except as may be provided in the proceedings under which they shall be issued.
Any bonds of the corporation may be sold at public or private sale in such manner and from time to time as may be determined by the board of directors of the corporation to be most advantageous, and the corporation may pay all expenses, premiums and commissions which its board of directors may deem necessary or advantageous in connection with the issuance thereof.
Any bonds of the corporation at any time outstanding may at any time and from time to time be refunded by the corporation by the issuance of its refunding bonds in such amount as the board of directors may deem necessary but not exceeding an amount sufficient to refund the principal of the bonds so to be refunded, together with any unpaid interest thereon and any premiums, commissions and expenses necessary to be paid in connection with such refunding. Any such refunding may be effected whether the bonds to be refunded shall have then matured or shall thereafter mature, either by sale of the refunding bonds and the application of the proceeds thereof for the payment of the bonds to be refunded thereby or by the exchange of the refunding bonds for the bonds to be refunded thereby with the consent of the holders of the bonds so to be refunded and regardless of whether or not the bonds to be refunded were issued in connection with the same projects or separate projects and regardless of whether or not the bonds proposed to be refunded shall be payable on the same date or different dates or shall be due serially or otherwise.
All such bonds and the interest coupons applicable thereto are hereby made and shall be construed to be negotiable instruments.
