(a) In the discretion of the authority, any issue of such bonds may be secured by a trust indenture by and between the authority and a corporate trustee, which may be any trust company or bank having the powers of a trust company inside or outside of the state.

(b) Resolutions providing for the issuance of bonds and trust indentures may contain such provisions for protecting and enforcing the rights and remedies of the bondholders, including the right to the appointment of a receiver for any project or projects upon the default of any principal or interest payment upon the bonds thereof, and the right of any receiver or indenture trustee to enforce collections of rents, revenues, or other charges for the use of the project or projects necessary to pay all costs of operation, the principal and interest on the issue, and cost of collection, and all things reasonably necessary to accomplish the collection of such sums in the event of any default of the authority.

(c) Such resolutions or trust indentures may include covenants setting forth the duties of the authority in relation to the acquisition of the property; the construction of the project; the maintenance, operation, repair, and insurance of the project; and the custody, safeguarding, and application of all moneys; may also provide that any project shall be constructed and paid for under the supervision of department engineers or others satisfactory to the original purchasers of the bonds issued for such project or projects. Such resolution or trust indenture may also require that the security given by contractors and by any depository of the proceeds of the bonds or revenues or other moneys be satisfactory to such purchasers and may also contain provisions concerning the conditions, if any, upon which additional revenue bonds may be issued.

(d) It shall be lawful for any bank or trust company incorporated under the laws of this state to act as such depository and to furnish such indemnifying bonds or pledge such securities as may be required by the authority. The trust indenture may set forth the rights and remedies of the bondholders and of the trustee and may restrict the individual right of action of bondholders as is customary in trust indentures securing bonds and debentures of corporations.

(e) In addition to the foregoing, such trust indenture may contain such other provisions as the authority may deem advisable, reasonable, and proper for the security of the bondholders. All expenses incurred in carrying out such trust indenture may be treated as a part of the cost of maintenance, operation, and repair of the project affected by such indenture or as an administrative expense of the authority.
