Section 8-15-2-13 - Trust agreements securing bond issue(a) 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, which may be any trust company or bank having the powers of a trust company within or without the state.(b) Any such trust agreement may pledge or assign the tolls and other revenue to be received from such project or any other project or projects constructed under the provisions of this chapter, subject only to valid prior pledges and except as provided by this chapter with respect to succeeding lien bonds, but shall not convey or mortgage any toll road project or any part thereof.(c) Any such trust agreement or any 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 covenants setting forth the duties of the authority in relation to: (1) the acquisition of property and the construction, improvement, maintenance, repair, operation, and insurance of the toll road project or projects in connection with which such bonds shall have been authorized, or of which the revenues are pledged;(2) the rates of toll to be charged, and the custody, safeguarding, and application of all moneys; and(3) the employment of consulting engineers in connection with the construction or operation of such project or projects.(d) It shall be lawful for any bank or trust company incorporated under the laws of the state which may act as depository of the proceeds of bonds or of revenue to furnish such indemnifying bonds or to pledge such securities as may be required by the authority.(e) Any such trust agreement may set forth the rights and remedies of the bondholders and of the trustee, and may restrict the individual right of action by bondholders as is customary in trust agreements or trust indentures securing bonds or debentures of corporations. In addition, any such trust agreement may contain such other provisions as the authority may deem reasonable and proper for the security of the bondholders.(f) All expenses incurred in carrying out the provisions of any such trust agreement may be treated as a part of the cost of the operation of the toll road project or projects.(Formerly: Acts 1951, c.281, s.13; Acts1971 , P.L. 99, SEC.3.)
