1. A district may, at any time, issue obligations for the purpose of carrying out any of its powers, duties or purposes. Such obligations shall be payable out of all, part or any combination of the revenues of the district and may be further secured by all or any part of any property or any interest in any property by mortgage or any other security interest granted. Such obligations shall be authorized by resolution of the district, and if issued by the district, shall bear such date or dates, and shall mature at such time or times, but not more than twenty years from the date of issuance, as the resolution shall specify. Such obligations shall be in such denomination, bear interest at such rate or rates, be in such form, be payable in such place or places, be subject to redemption as such resolution may provide and be sold at either public or private sale at such prices as the district shall determine subject to the provisions of section 108.170. The district may also issue such obligations to refund, in whole or in part, obligations previously issued by the district.

2. No obligation issued by a district that is a political subdivision shall constitute an indebtedness within the meaning of any constitutional, statutory or charter debt limitation or restriction. No such obligation shall be a general obligation of the district, municipality, county, state of Missouri or any political subdivision thereof, and shall not be payable out of any funds or properties other than those specifically pledged as security therefor, unless such obligation is issued as an indebtedness of the district with the approval of the qualified voters as required by the constitution in which instance the obligation shall be a general obligation of the district only.

3. Obligations issued pursuant to this section by a district which is a political subdivision, the interest thereon, and any proceeds from such obligations shall be exempt from taxation in the state of Missouri.

4. The municipality, any land clearance for redevelopment authority, port authority, tax increment financing commission, industrial development authority or planned industrial expansion authority of the municipality may, pursuant to a cooperative agreement with a district, issue obligations and loan the proceeds of such obligations to the district for the purpose of carrying out the powers, duties or purposes of the district.
