      Diamond   Cable   Communications   Plc,   which   owns  and   operates   a
telecommunications  and cable  television  business focused on the East Midlands
area of England,  today  announced  that all of the  holders of its  outstanding

Diamond  for  newly  issued  shares  of  Common  Stock of NTL  Incorporated,  an
alternative  telecommunications  company in the UK, the common stock of which is
quoted on NASDAQ (NTLi).


      Under the Share Exchange Agreement, Diamond shareholders will receive four
shares of NTL common  stock for each  Diamond  Ordinary  Share  held  subject to
adjustment  in the event that the average  NTL share  price for a  predetermined
period before closing of the  transaction  exceeds a specified price (which will

approval by NTL  shareholders  and the  consent of holders of NTL's  outstanding
debt.  The  transaction  will not require  the prior  approval of the holders of
Diamond's  outstanding  debt  securities,   but  will  require  that  offers  to
repurchase such debt securities be made to holders of such securities subsequent
to closing. The parties expect the transaction to be completed in autumn of this
year.
