Section 559 - Bonds of an agency1.(a) An agency shall have power and is hereby authorized from time to time to issue its negotiable bonds and notes in conformity with applicable provisions of the uniform commercial code in such principal amount as, in the opinion of the agency, shall be necessary to provide sufficient funds for achieving its corporate purposes.(b) An agency shall have power, from time to time, to refund any bonds by the issuance of new bonds, whether the bonds to be refunded have or have not matured, and to issue bonds partly to refund bonds then outstanding and partly for any other purpose. The refunding bonds shall be sold and the proceeds applied to the purchase, redemption or payment of the bonds to be refunded.2. Except as may otherwise be expressly provided by the agency, every issue of its notes and bonds shall be general obligations of the agency payable out of any revenues or moneys of the agency, subject only to any agreements with the holders of particular notes or bonds pledging any particular receipts or revenues, provided, however, that the payment of such bonds and notes, both as to principal and interest, may be further secured by a pledge of any loan, grant, or contribution from the federal government or other source, in aid of any urban renewal program or part thereof, or by a mortgage of any such urban renewal program, or part thereof, title to which is in the agency, or that payment of such bonds and notes, both as to principal and interest, or only as to interest, may be guaranteed by the municipality.3. Bonds and notes of an agency shall be authorized by its resolution, shall bear such date or dates, mature at such time or times, in the case of any such note, or any renewals thereof, not exceeding seven years from the date of issue of such original note, and in the case of any such bond not exceeding fifty years from the date of issue, as such resolution or resolutions shall provide. The notes and bonds shall bear interest at such rate or rates, be in such denomination or denominations, be in such form, either coupon or registered, carry such registration privileges, be executed in such manner, be payable in such medium of payment, at such place or places and be subject to such terms of redemption with or without premium, and be secured in such manner, as such resolution or resolutions may provide. The bonds and notes may be sold by the agency at public or private sale, at such price or prices as the agency may determine.4.

In case any of the members or officers of an agency whose signatures appear on the bonds or coupons shall cease to be such members or officers before the delivery of such bonds, such signatures shall, nevertheless, be valid and sufficient for all purposes, the same as if they had remained in office until such delivery.6.
