(5)The re-issue of a debenture or the issue of another debenture in its place under the power by this section given to, or deemed to have been possessed by, a company, whether the re-issue or issue was made before or after the commencement of this Act, shall be treated as the issue of a new debenture for the purposes of stamp duty, but it shall not be so treated for the purposes of any provision limiting the amount or number of debentures to be issued:Provided that any person lending money on the security of a debenture re-issued under this section which appears to be duly stamped may give the debenture in evidence in any proceedings for enforcing his security without payment of the stamp duty or any penalty in respect thereof, unless he had notice or, but for his negligence, might have discovered, that the debenture was not duly stamped; but in any such case the company shall be liable to pay the proper stamp duty and penalty.
