(C) Obligations and assurances shall be secured by a pledge of and lien on all or such part of the available receipts of the institution of higher education as it provides for in the bond proceedings, excluding moneys raised by taxation and state appropriations except as permitted by section 3333.59 of the Revised Code. Such pledge and lien may be made prior to all other expenses, claims, or payments, excepting any pledge of such available receipts previously made to the contrary and except as provided by any existing restrictions on the use thereof, or such pledge and lien may be made subordinate to such other expenses, claims, or payments, as provided in the bond proceedings. Obligations or assurances may be additionally secured by covenants of the institution to make, fix, adjust, collect, and apply such charges, rates, fees, rentals, and other items of available receipts as will produce pledged available receipts sufficient to meet bond service charges, reserve, and other requirements provided for in the bond proceedings. Notwithstanding this and any other sections of the Revised Code, the holders or owners of the obligations or assurances shall not be given the right and shall have no right to have excises or taxes levied by the general assembly for the payment of bond service charges thereon, and each such obligation or assurance shall bear on its face a statement to that effect and to the effect that the right to such payment is limited to the available receipts and special funds pledged to such purpose under the bond proceedings. All pledged available receipts and funds and the proceeds of obligations or assurances are trust funds and, subject to the provisions of this section and the applicable bond proceedings, shall be held, deposited, invested, reinvested, disbursed, applied, and used to such extent, in such manner, at such times, and for such purposes, as are provided in the bond proceedings.
