In the discretion of the authority any bonds issued under the provisions of this chapter may be secured by a trust agreement by and between the authority and a corporate trustee or trustees, which may be any trust company or bank having the powers of a trust company within or without the state. Such trust agreement or the resolution providing for the issuance of such bonds or other instrument of the authority may secure such bonds by a pledge or assignment of any revenues to be received, any contract or proceeds of any contract, or any other property, revenues, moneys or funds available to the authority for such purpose. Any pledge made by the authority pursuant to this section shall be valid and binding from the time when the pledge is made. The lien of any such pledge shall be valid and binding as against all parties having claims of any kind in tort, contract or otherwise against the authority, irrespective of whether the parties have notice of the claims. Notwithstanding any provision of the Uniform Commercial Code, no instrument by which such pledge is created need be recorded or filed. Any revenues or other receipts, funds, moneys, income, contracts or property so pledged and thereafter received by the authority shall be subject immediately to the lien of the pledge without any physical delivery thereof or further act and such lien shall have priority over all other liens. Such trust agreement or other instrument may mortgage, assign or convey any real property to secure such bonds. Such trust agreement or resolution providing for the issuance of such bonds may contain such provisions for protecting and enforcing the rights and remedies of the bondholders as may be reasonable and proper and not in violation of law, including particularly such provisions as have hereinabove been specifically authorized to be included in any resolution or resolutions of the authority authorizing bonds thereof. Any bank or trust company incorporated under the laws of this state which may act as depositary of the proceeds of bonds or of revenues or other moneys may furnish such indemnifying bonds or pledge such securities as may be required by the authority. Any such trust agreement may set forth the rights and remedies of the bondholders and of the trustee or trustees, and may restrict the individual right of action by bondholders. In addition to the foregoing, any such trust agreement or resolution may contain such other provisions as the authority may deem reasonable and proper for the security of the bondholders. All expenses incurred in carrying out the provisions of such trust agreement or resolution may be treated as a part of the cost of the operation of a project.
