Any county commission issuing revenue bonds under the provisions of this article shall thereafter, so long as any such bonds remain outstanding, operate and maintain said courthouse, hospital, other public buildings, jail or regional correctional center, to provide revenues sufficient to pay all operating costs, provide a sinking fund for, and to retire such bonds and pay the interest thereon as the same may become due. The amounts, as and when so set apart by said county commission, shall be remitted to the West Virginia Municipal Bond Commission at least thirty days previous to the time interest or principal payments become due, to be retained and paid out by said commission consistent with the provisions of this article and with the order pursuant to which the bonds have been issued. The West Virginia Municipal Bond Commission is hereby authorized to act as fiscal agent for the administration of such sinking fund under any order passed pursuant to the provisions of this article, and shall invest all sinking funds, as provided by general law. Notwithstanding the foregoing, payments of principal and interest on any bonds owned by the United States or any governmental agency or department thereof may be made by the county commission directly thereto. Revenue bonds issued under the provisions of this article are hereby declared to be and to have all the qualities of negotiable instruments. Such bonds shall bear interest at the rate or rates set by the county commission, not to exceed twelve percent per annum, payable semiannually, and shall mature at any time fixed by the county commission, in not more than thirty years from their date. Such bonds shall be sold at a price not lower than a price which, when computed upon standard tables of bond values, will show a net return of not more than thirteen percent per annum to the purchaser upon the amount paid therefor. Such bonds may be made redeemable at the option of the county commission at such price and under terms and conditions as said county commission may fix, by its order, prior to the issuance of such bonds. Revenue bonds issued hereunder shall be payable at the office of the State Treasurer, or a designated bank or trust company within or without the State of West Virginia.

In case any of the officers whose signatures appear on such bonds or coupons shall cease to be such officers before the delivery of such bonds, such signatures shall, nevertheless, be valid and sufficient for all purposes the same as if they had remained in office until such delivery. The county commission shall by order entered prior to the issuance of said bonds, fix the denominations, times and places of payment of such bonds, the principal and interest of which shall be payable in lawful money of the United States of America. The proceeds of such bonds shall be used solely for the payment of the cost of land, buildings, furniture and equipment thereon, and shall be checked out by the county commission under such restrictions as are contained in the order providing for the issuance of said bonds. If the proceeds of such bonds issued for any courthouse, hospital, other public buildings, jail or regional correctional center, shall exceed the cost thereof, the surplus shall be paid into the fund herein provided for the payment of principal and interest upon such bonds. Such fund may be used for the purchase or redemption of any of the outstanding bonds payable from such fund at the market price, but at not exceeding the price at which any of such bonds shall in the same year be redeemable, as fixed by the commission in its said order, and all bonds redeemed or purchased shall forthwith be canceled, and shall not again be issued.

Prior to the preparation of definitive bonds, the county commission may, under like restrictions, issue temporary bonds, or interim certificates, with or without coupons, exchangeable for definitive bonds upon the issuance of the latter. Such bonds may be issued without any other proceedings or the happening of any other conditions or things than those proceedings, conditions and things which are specified and required by this article.
