Fla. Stat. § 243.74
The state agrees with the holders of any obligations issued under ss. 243.50 - 243.77, and with those parties who may enter into contracts with the authority under ss. 243.50 - 243.77, that the state will not limit or alter the rights vested in the authority until the obligations, together with the interest thereon, are fully met and discharged and the contracts are fully performed on the part of the authority. However, ss. 243.50 - 243.77 do not preclude any limitation or alteration if adequate provision is made by law for the protection of the holders of the obligations of the authority or those entering into contracts with the authority. The authority may include this pledge and undertaking for the state in any obligations or contracts.
