In the discretion of the municipalities any bonds issued under sections 7-136n to 7-136s, inclusive, may be secured by a trust indenture by way of conveyance, deed of trust or mortgage of any project or any other property of the municipalities, whether or not financed in whole or in part from the proceeds of such bonds, or by a trust agreement by and between the municipalities and a corporate trustee, which may be any trust company or bank having the powers of a trust company within or without the state or by both such conveyance, deed of trust or mortgage and indenture or trust agreement. Such trust indenture or agreement may pledge or assign any or all fees, rents and other charges to be received or proceeds of any contract or contracts pledged, and may convey or mortgage any property of the municipalities. Such trust indenture or agreement 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 municipalities authorizing the issue of bonds. Any bank or trust company incorporated under the laws of the state may act as depository of the proceeds of such bonds or of revenues or other moneys and may furnish such indemnifying bonds or pledge such securities as may be required by the municipalities. Such trust indenture may set forth the rights and remedies of the bondholders and of the trustee, and may restrict the individual right of action by bondholders. In addition to the foregoing, such trust indenture or agreement may contain such other provisions as the municipalities may deem reasonable and proper for the security of the bondholders. All expenses incurred in carrying out the provisions of such trust indenture or agreement may be treated as a part of the cost of a project.
