In the discretion of the authority any bonds issued under the Nebraska Educational, Health, Cultural, and Social Services Finance Authority Act may be secured by a trust indenture, which trust indenture may be in the form of a bond resolution or similar contract, by and between the authority and a corporate trustee or trustees which may be any financial institution having the power of a trust company or any trust company within or outside the state. Such trust indenture providing for the issuance of such bonds may pledge or assign the revenue to be received or proceeds of any contract or contracts pledged and may convey or mortgage the project or any portion thereof. The trust indenture by which a pledge is created or an assignment made shall be filed in the records of the authority.

Any pledge or assignment made by the authority pursuant to this section shall be valid and binding from the time that the pledge or assignment is made, and the revenue so pledged and thereafter received by the authority shall immediately be subject to the lien of such pledge or assignment without physical delivery thereof or any further act. The lien of such pledge or assignment shall be valid and binding against all parties having claims of any kind in tort, contract, or otherwise against the authority irrespective of whether such parties have notice thereof.

Such trust indenture may set forth the rights and remedies of the bondholders and of the trustee or trustees, may restrict the individual right of action by bondholders, and may contain such provisions for protecting and enforcing the rights and remedies of the bondholders and of the trustee or trustees as may be reasonable and proper, not in violation of law, or provided for in the Nebraska Educational, Health, Cultural, and Social Services Finance Authority Act. Any such trust indenture may contain such other provisions as the authority may deem reasonable and proper for the security of the bondholders.

Any bank or trust company which acts as depository of the proceeds of the bonds, any revenue, or other money shall furnish such indemnifying bonds or pledge such securities as may be required by the authority.

All expenses incurred in carrying out the provisions of such trust indenture may be treated as a part of the cost of the operation of a project.
