National Grid is currently undertaking a share repurchase programme. Where
repurchases are made, separate covering announcements will, as required,
identify numbers being repurchased and the supporting details indicate resultant
share capital after market settlement and transfer to Treasury, or cancellation,
of the shares involved (and any earlier repurchases which remain to be
registered).
