The principal of and interest on any bonds issued by the corporation shall be secured by a pledge of the revenues out of which the same shall be made payable and may be secured by a mortgage or deed of trust covering all or any part of the facilities from which the revenues so pledged may be derived, including all supplies, equipment and easement in connection with such facilities and any enlargements of and additions to any thereof thereafter made. Any such mortgage or deed of trust and the resolution under which the bonds are authorized to be issued may contain any agreements and provisions respecting the management, operation and maintenance of the facilities covered thereby, the fixing and collection of rents, fees and charges for any portions thereof leased by the corporation or used by the public or any services rendered respecting the same, the creation and maintenance of special funds from such revenues and the rights and remedies available in the event of default as the board of directors shall deem advisable; except, that no such properties may be sold in foreclosure of such mortgage and deed of trust. Whenever the corporation shall have any of its bonds outstanding, it shall charge, collect and account for sufficient revenues from the operation and lease of its facilities as may be necessary to pay all expenses of operating and maintaining its facilities and as may further be necessary to pay the principal of and interest on its bonds as such principal and interest shall mature and to maintain any special funds which may be provided for in the proceedings pursuant to which such bonds shall have been issued. Each pledge, agreement, mortgage and deed of trust made for the benefit or security of any of the bonds of the corporation shall continue effective until the principal of and interest on the bonds for the benefit of which the same were made shall have been fully paid.
No such mortgage or deed of trust shall be subject to foreclosure and, in the event of default in the payment of the principal of or interest on the bonds secured thereby or in any of the agreements on the part of the corporation contained therein, the remedies available shall be limited either to mandamus to compel performance of the obligations and agreements of the corporation with respect to which the corporation may be in default or to the appointment, as a matter of right, by any court having jurisdiction over the corporation of a receiver with all the powers of such a receiver, including the power under the jurisdiction of such court to operate and lease or license for use by others all or any of its facilities of the corporation and to charge and collect charges, fees and rents for admission to and use of the facilities of the corporation and for the services rendered by it and to apply the revenues so collected toward the expenses of such receivership and the payment of the principal of and interest on the bonds of the corporation. There is hereby granted to any receiver so appointed power to charge and collect such charges, fees and rents for such purposes under the jurisdiction of the court appointing such receiver.
