An entity created to carry out an agreement authorizing the joint exercise of those governmental powers enumerated in section 28F.1 shall have power to construct, acquire, own, repair, improve, expand, operate and maintain a project or projects necessary to carry out the purposes of such agreement, and to issue from time to time revenue bonds payable from the revenues derived from such project or projects, or any combination of such projects, to finance the cost or part of the cost of the acquisition, construction, reconstruction, repair, extension or improvement of such project or projects, including the acquisition for the purposes of such agreement, of any property, real or personal or mixed therefor. The power of the entity to issue revenue bonds shall not be exercised until authorized by resolution duly adopted by each of the public agencies participating in such agreement. Public agencies participating in such an agreement may not withdraw or in any way terminate, amend, or modify in any manner to the detriment of the bondholders said agreement if revenue bonds or obligations issued in anticipation of the issuance of said revenue bonds have been issued and are then outstanding and unpaid as provided for herein. Any revenue bonds for the payment and discharge of which, upon maturity or upon redemption prior to maturity, provision has been made through the setting apart in a reserve fund or special trust account created pursuant to this chapter to insure the payment thereof, of moneys sufficient for that purpose or through the irrevocable segregation for that purpose in a sinking fund or other fund or trust account of moneys sufficient therefor, shall be deemed to be no longer outstanding and unpaid within the meaning of any provision of this chapter.
