Notwithstanding any provision in Section 2.20 (a) (ii) of this Act to the contrary, in connection with or incidental to the issuance by the Authority of its bonds or notes under the provisions of Section 4.04 or the exercise of its powers under subsection (b) of Section 2.20, the Authority, for its own benefit or for the benefit of the holders of its obligations or their trustee, may enter into rate protection contracts. The Authority may enter into rate protection contracts only pursuant to a determination by a vote of 12 of the then Directors that the terms of the contracts and any related agreements reduce the risk of loss to the Authority, or protect, preserve or enhance the value of its assets, or provide compensation to the Authority for losses resulting from changes in interest rates. The Authority's obligations under any rate protection contract or credit enhancement or liquidity agreement shall not be considered bonds or notes for purposes of this Act. For purposes of this Section a rate protection contract is a contract determined by the Authority as necessary or appropriate to permit it to manage payment, currency or interest rate risks or levels.
