(a) The principal of and interest on any bonds issued by the authority 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 authority's interest in and rights under the leases, sales contracts, or loan agreements relating to such projects, or any part thereof. The proceedings 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 for any portions thereof leased by the authority to others, the creation and maintenance of special funds from such revenues 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 chapter. Each pledge, agreement, mortgage and deed of trust made for the benefit or security of any of the bonds of the authority 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 authority 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, such 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 such remedies.

(b) The board of directors of any authority issuing bonds under provisions of this chapter shall charge, collect and revise from time to time, whenever necessary, rents and charges for the rental of projects or parts thereof or installment payments under any loan agreement or sales contract with respect thereto, the revenues from which are pledged to the payment of such bonds, sufficient to pay for the operation and maintenance of such projects and such portion of the administrative costs of the authority as may be provided in the lease or leases of such projects or the loan agreement or agreements or the sales contract or contracts with respect thereto, and to pay such bonds and the interest thereon as the same become due, including such reserves as may be determined to be necessary by the board of directors.
