§ 159‑97.  Taxes for supplementing revenue bond projects.
(a)	For the purpose of supplementing the revenues of a revenue bond project, as defined in this section, any county or city may covenant with, or may enter into an agreement with a municipality for the benefit of the holders of revenue bonds of the issuing municipality issued pursuant to this Article, whereby such county or city agrees to:
(1)	Levy for the life of all revenue bonds issued in connection with the revenue bond project an annual property tax not in excess of the rate set forth in the question submitted to voters as hereinafter provided, such levy to be based upon the operating supplement requirement, as defined in this section, or
(2)	Levy for the life of the revenue bonds in respect of which such tax is being levied an annual property tax not in excess of the rate required to pay the principal of and the interest on the aggregate principal amount of revenue bonds set forth in the question submitted to the voters as hereinafter provided, such levy to be based upon the debt service reserve supplement requirement, as defined in this section.
When any such covenant has been made or any such agreement has been entered into, the issuing municipality shall determine, and, in those instances in which the issuing municipality is not also the taxing county or city, the issuing municipality shall certify to the governing board of the taxing county or city, by not later than June 1 of each fiscal year the amount required, determined as hereinafter provided, to be raised by taxation by such county or city in the next fiscal year. The county or city is obligated to levy such tax only to the extent that an operating supplement requirement or a debt service reserve supplement requirement shall occur during the fiscal year preceding the fiscal year in which the tax is to be levied. In no event shall the county or city be required to levy a tax in excess of the rate required to be levied in accordance with the approval of the voters as provided in subsection (c). When any such tax is to be levied, the county or city shall include in its budget ordinance an appropriation to the issuing municipality or the appropriate fund, as the case may be, equal to the estimated yield of the tax levy, and shall pay such appropriation to the issuing municipality or transfer moneys to the appropriate fund in equal monthly installments unless another mutually satisfactory schedule of payments is agreed upon.
(b)	A covenant made, or the pledge of an agreement entered into, by a county or city pursuant to this section shall be effected by the provisions of the revenue bond order or the trust agreement securing revenue bonds of the issuing municipality and where the issuing municipality is not also the taxing county or city a resolution of the county or city approving the appropriate provisions of the bond order or trust agreement relating to the pledge of the tax. If the taxing county or city is not the issuing municipality, it shall file an application for approval of the resolution with the secretary of the Commission in the manner provided in G.S. 159‑149, and the Commission shall determine whether to approve the application as provided by G.S. 159‑151 and 159‑152; provided, however, that G.S. 159‑148 and 159‑150 shall have no application to this section.
(c)	A covenant made, or agreement entered into, by a county or city pursuant to this section shall take effect only if approved by the affirmative vote of a majority of those who vote thereon in a referendum held in the taxing county or city. The referendum shall be called and held as provided in G.S. 159‑61, except that

After the expiration of this period of limitation, no right of action or defense based upon the invalidity of or any irregularity in the referendum shall be asserted, nor shall the validity of the referendum be open to question in any court upon any ground whatever, except in an action or proceeding begun within the period of limitation prescribed in this subsection.
(e)	An order or agreement submitted to and approved by the voters pursuant to this section may be repealed at any time before bonds are issued pursuant thereto.
