Support facility for variable rate revenue bonds

If revenue bonds issued pursuant to this chapter are issued bearing interest at a rate or rates which vary from time to time and with a right of holders to tender the revenue bonds for purchase, the governing body may authorize the director of finance to contract for such support facility or facilities and remarketing arrangements as are required to market the revenue bonds to the greatest advantage of the county upon such terms and conditions as deemed necessary and proper. The director of finance may enter into contracts or agreement with the entity or entities providing a support facility; provided that any contract or agreement shall provide, in essence, that any amount due and owing by the county under the contract or agreement on an annual basis shall be payable solely from the revenue of the undertaking or loan program and any obligation issued or arising pursuant to the terms of the contract or agreement in the form of bonds, notes, or other evidences of indebtedness shall only arise at such time as either: (1) Moneys or securities have been irrevocably set aside for the full payment of a like principal amount of revenue bonds issued pursuant to this chapter; or (2) A like principal amount of the issue or series of revenue bonds to which the support facility relates are held in escrow by the entity or entities providing the support facility.
