Section 261A.44 - Obligations secured by trust agreement1. Obligations issued under this subchapter may be secured by a trust agreement by and between the authority and an incorporated trustee, which may be a trust company or bank having the powers of a trust company within or without the state. The trust agreement or the resolution providing for the issuance of the obligations may pledge or assign the revenue to be received or proceeds of any contract pledged and may convey or mortgage the project or any portion of the project.2. A pledge or assignment made by the authority pursuant to this section is valid and binding from the time that the pledge or assignment is made, and the revenue pledged and thereafter received by the authority is immediately subject to the lien of the pledge or assignment without physical delivery or any further act. The lien of the pledge or assignment is valid and binding against all parties having claims of any kind in tort, contract, or otherwise against the authority irrespective of whether the parties have notice of the lien.3. The resolution or trust agreement by which a pledge is created or an assignment made shall be filed or recorded in the records of the authority, with the secretary of state, and in each county in which the project is located.4. The trust agreement or resolution providing for the issuance of the obligations may contain provisions for protecting and enforcing the rights and remedies of the obligation holders as are reasonable and proper, not in violation of law, or provided for in this subchapter. A bank or trust company incorporated under the laws of this state which acts as depository of proceeds of the obligations, revenue, or other money shall furnish the indemnifying obligations or pledge the securities as required by the authority. The trust agreement may set forth the rights and remedies of the obligation holders and of the trustee, and may restrict the individual right of action by obligation holders. The trust agreement or resolution may contain other provisions the authority deems reasonable and proper for the security of the obligation holders.5. Expense incurred in carrying out the trust agreement or resolution may be treated as a part of the cost of the operation of a project.
