When the Director of the Department of Business and Industry has received requests from one or more charter schools, lessees, purchasers or other obligors, the Director of the Department of Business and Industry may issue revenue bonds to obtain money to fulfill the requests. Title to or in a project may at all times remain in the obligor or the obligor’s designee or assignee and, in that case, the bonds must be secured by a pledge of one or more notes, debentures, bonds or other secured or unsecured debt obligations of the obligor.
