Disposition of property.

A cooperative may not sell, mortgage, lease or otherwise dispose of or encumber all or any substantial portion of its property unless such sale, mortgage, lease, or other disposition or encumbrance is authorized at a duly held meeting of the members thereof by the affirmative vote of not less than two-thirds of all of the members of the cooperative, and unless the notice of such proposed sale, mortgage, lease or other disposition or encumbrance shall have been contained in the notice of the meeting. However, notwithstanding anything herein contained, or any other provisions of law, the board of trustees of a cooperative, without authorization by the members thereof, shall have full power and authority to authorize the execution and delivery of a mortgage or deed of trust upon, or the pledging or encumbering of, any or all of the property, assets, rights, privileges, licenses, franchises and permits of the cooperative, whether acquired or to be acquired, and wherever situated, as well as the revenues and income therefrom, all upon such terms and conditions as the board of trustees shall determine, to secure any indebtedness of the cooperative to the United States or any instrumentality or agency thereof or to any bank, financial institution, corporation, or person lending money or credit to such cooperative.
