NGT today received a further notification from the ESOP Trustee; that certain Executive Directors of NGT (E Astle, S Holliday, R Urwin and N Winser) ceased to be technically interested in a total of 17,425 NGT Ordinary shares, by virtue of the Trustee having transferred the shares to a participant on 24 May 2005.

His total personal interest in NGT shares is unchanged, as he retained the shares.
