Tennessee Code Title 48. Corporations and Associations § 48-101-311

(a) The principal of and interest on any bonds issued by the corporation shall be secured by a pledge of the revenues and receipts 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 projects from which the revenues or receipts so pledged may be derived, including any enlargements of and additions to any such projects thereafter made, and by an assignment and pledge of all or any part of the corporation's interest in and rights under the leases, sale contracts or loan agreements relating to such projects, or any thereof.

(b) The resolution under which the bonds are authorized to be issued and any such mortgage or deed of trust may contain any agreements and provisions respecting the maintenance of the projects covered thereby; the fixing and collection of rents or payments with respect to any projects or portions thereof covered by such resolution, mortgage or deed of trust, the creation and maintenance of special funds from such revenues and from the proceeds of such bonds, and the rights and remedies available in the event of default, all as the board of directors shall deem advisable and not in conflict with this part.

(c) 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. In the event of default in such payment or in any agreement of the corporation made as a part of the contract under which the bonds were issued, whether contained in the proceedings authorizing the bonds or in any mortgage and deed of trust executed as security therefor, the payment or agreement may be enforced by suit, mandamus, the appointment of a receiver in equity or by foreclosure of any such mortgage and deed of trust, or any one (1) or more of these remedies.
