Section A1–112. Revenue Bonds.
   (a)   In addition to the authority conferred by Section A1–111 of this appendix, the municipality may issue revenue bonds to finance the undertaking of any urban renewal project and related activities. Also, it may issue refunding bonds for the payment or retirement of the bonds issued previously by it. The bonds shall be made payable, as to both principal and interest, solely from the income, proceeds, revenues, and funds of the municipality derived from or held in connection with its undertaking and carrying out of urban renewal projects under this appendix. However, payment of the bonds, 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 projects of the municipality under this appendix, and by a mortgage of any urban renewal project, or any part of a project, title to which is in the municipality. In addition, the municipality may enter into an indenture of trust with any private banking institution of this State having trust powers and may make in the indenture of trust covenants and commitments required by any purchaser for the adequate security of the bonds.
   (b)   Bonds issued under this section do not constitute an indebtedness within the meaning of any constitutional or statutory debt limitation or restriction, are not subject to the provisions of any other law or charter relating to the authorization, issuance or sale of bonds, and are exempted specifically from the restrictions contained in Sections 9, 10, and 11 of Article 31 (debts – public) of the Annotated Code of Maryland. Bonds issued under the provisions of this appendix are declared to be issued for an essential public and governmental purpose and, together with interest on them and income from them, are exempt from all taxes.
   (c)    Bonds issued under this section shall be authorized by resolution or ordinance of the legislative body of the municipality. They may be issued in one or more series and:
      (1)   Shall bear a date or dates,
      (2)   Mature at time or times,
      (3)   Bear interest at a rate or rates,
      (4)   Be in a denomination or denominations,
      (5)   Be in a form either with or without coupon or registered,
      (6)   Carry a conversion or registration privilege,
      (7)   Have a rank or priority,
      (8)   Be executed in a manner,
      (9)   Be payable in a medium or payment, at a place or places, and be subject to terms of redemption (with or without premium),
      (10)   Be secured in a manner, and
      (11)   Have other characteristics, as are provided by the resolution, trust indenture or mortgage issued pursuant to it.
   (d)   These bonds may not be sold at less than par value at public sales which are held after notice is published prior to the sale in a newspaper having a general circulation in the area in which the municipality is located and in whatever other medium of publication as the municipality may determine. The bonds may be exchanged also for other bonds on the basis of par. However, the bonds may be sold to the Federal Government at private sale at less than par, and, in the event less than all of the authorized principal amount of the bonds is sold to the Federal Government, the balance may be sold at private sale at less than par at an interest cost to the municipality which does not exceed the interest cost to the municipality of the portion of the bonds sold to the Federal Government.
   (e)   In case any of the public officials of the municipality whose signatures appear on any bonds or coupons issued under this appendix cease to be officials of the municipality before the delivery of the bond, or, in the event any of the officials have become such after the date of issue of them, the bonds are valid and binding obligations of the municipality in accordance with their terms. Any provision of any law to the contrary notwithstanding, any bonds issued pursuant to this appendix are fully negotiable.
   (f)   In any suit, action or proceeding involving the validity or enforceability of any bond issued under this appendix, or the security for it, any bond which recites in substance that it has been issued by the municipality in connection with an urban renewal project shall be considered conclusively to have been issued for that purpose, and the project shall be deemed conclusively considered to have been planned, located and carried out in accordance with the provisions of this appendix.
   (g)   All banks, trust companies, bankers, savings banks and institutions, building and loan associations, savings and loan associations, investment companies and other persons carrying on a banking or investment business; all insurance companies, insurance associations, and other persons carrying on an insurance business; and all executors, administrators, curators, trustees, and other fiduciaries, may legally invest any sinking funds, monies or other funds belonging to them or within their control in any bonds or other obligations issued by the municipality pursuant to this appendix. The bonds and other obligations shall be secured by an agreement between the issuer and the Federal Government in which the issuer agrees to borrow from the Federal Government and the Federal Government agrees to lend to the issuer, prior to the maturity of the bonds or other obligations, monies in an amount which (together with any other monies committed irrevocably to the payment of principal and interest on the bonds or other obligations) will suffice to pay the principal of the bonds or other obligations with interest to maturity on them. The monies under the terms of the agreement shall be required to be used for the purpose of paying the principal of and the interest on the bonds or other obligations at their maturity. The bonds and other obligations shall be authorized security for all public deposits. This section authorizes any persons or public or private political subdivisions and officers to use any funds owned or controlled by them for the purchase of any bonds or other obligations. With regard to legal investments, this section may not be construed to relieve any person of any duty of exercising reasonable care in selecting securities.
