(1) Whenever a proposal to issue bonds for any purpose authorized in this article has been approved at an election held in accordance with this article, the district may borrow money without any other election in anticipation of sales taxes or of the receipt of the proceeds of said bonds and to issue interim notes to evidence the amount so borrowed; except that the aggregate amount of the interim notes may not exceed the amount so authorized by the election. Any interim notes may mature at such time not exceeding a period of time equal to the estimated time needed to effect the purposes for which the bonds are authorized to be issued, plus two years, as the board may determine. Except as otherwise provided in this section, interim notes shall be issued as provided in this article for district securities.

(2) Sales taxes, proceeds of bonds to be thereafter issued or reissued, and bonds issued for the purpose of securing the payment of interim notes, or any combination thereof, may be pledged for the purpose of securing the payment of the interim notes. Any bonds pledged as collateral security for the payment of any interim notes shall mature at such time as the board may determine, but in no event exceeding forty years from the date of either any of such bonds or any of such interim notes, whichever date is the earlier. Any such bonds pledged as collateral security shall not be issued in an aggregate principal amount exceeding the aggregate principal amount of the interim notes or interim notes secured by a pledge of such bonds, nor shall they bear interest at any time which, with any interest accruing at the same time on the interim notes so secured, exceeds the maximum net effective interest rate authorized.

(3) For the purpose of funding any interim notes, any bonds pledged as collateral security to secure the payment of such interim notes, upon their surrender as pledged property, may be reissued without an election, and any bonds not previously issued but authorized to be issued at an election may be issued for such a funding. Any such bonds shall mature at such time as the board may determine, but in no event exceeding forty years from the date of either any of the interim notes so funded or any of the bonds so pledged as collateral security, whichever date is earlier. Bonds may be issued separately or issued in combination in one series or more. Except as otherwise provided in this section any such funding bonds shall be issued as is provided in this article for district securities.

(4) No interim note issued pursuant to the provisions of this section shall be extended or funded except by the issuance or reissuance of a bond in compliance with the provisions of this section.
