Code of Alabama
Chapter 15 - Public Building Authorities.
Section 11-15-12 - Warrants - Security for Payment of Principal and Interest.

The principal of and interest on the warrants shall be secured by a pledge of the revenues out of which the warrants shall be made payable, shall be secured by a mortgage covering the project from which the revenues so pledged shall be derived and shall be secured by a pledge of the lease agreement covering such project and of the rental therefrom.
The mortgage may contain any agreements and provisions customarily contained in instruments securing evidences of indebtedness, including, without limiting the generality of the foregoing, provisions respecting the collection and application of the rental from any project covered by such mortgage, the terms to be incorporated in the lease agreement respecting such project, the maintenance and insurance of such project, the creation and maintenance of special funds from the rental of such project and the rights and remedies available in the event of default to the holders of the warrants or the trustee under the mortgage, all as the governing body shall deem advisable and as shall not be in conflict with the provisions of this chapter; provided, that in making any such agreements or provisions the corporation shall not have the power to obligate itself except with respect to the project and the application of the revenues therefrom.
If there is any default by the corporation in the payment of the principal of or interest on the warrants or in any of the agreements on the part of the corporation which may properly be included in any mortgage securing the warrants, any holder of any of the warrants or any of the coupons or the trustee under any mortgage, if so authorized in such mortgage, may, either by civil action, mandamus or other proceedings enforce payment of such items and compel performance of all duties of the directors and officers of the corporation and shall be entitled as a matter of right and regardless of the sufficiency of any such security to the appointment of a receiver with all the powers of such receiver for the operation and maintenance of the project covered by such mortgage and the collection and application of rents therefrom; provided, that any such mortgage shall not be subject to foreclosure and shall not be construed so as to compel the sale of the project covered thereby or any part thereof in satisfaction of the warrants secured thereby. The mortgage may contain provisions regarding the rights and remedies of any trustee thereunder and the holders of the warrants and the coupons and may contain provisions restricting the individual rights of action of the holders of the warrants and coupons.
