The board may borrow money for any corporate purpose from any bank or other financial institution provided such money shall be repaid within 2 years from the time the money is borrowed. The president and secretary shall execute a promissory note or similar debt instrument to evidence the indebtedness incurred by the borrowing. The obligation to make the payments due under the promissory note or other debt instrument shall be a lawful direct general obligation of the park district payable from the general funds of that district and such other sources of payment as are otherwise lawfully available. The promissory note or other debt instrument shall be authorized by an ordinance passed by the board and shall be valid whether or not an appropriation with respect to that ordinance is included in any annual or supplemental appropriation adopted by the board. The indebtedness incurred under this Section, when aggregated with the existing indebtedness of the park district, may not exceed any debt limitation otherwise provided for by law.
