thereof,  plus accrued and unpaid interest and any other amounts payable thereon
to the date of redemption in the event of certain tax law changes  requiring the

Change of Control, the Issuer is required to offer to repurchase all outstanding
Senior Notes at 101% of their principal  amount plus accrued and unpaid interest
and  any  other  amounts  payable  thereon  to  the  date  of  repurchase.   See

Issuer  would have the  financial  resources  necessary  or otherwise be able to

         Diamond  Holdings plc is a  wholly-owned  subsidiary  of Diamond  Cable
Communications  Plc.  The  Senior  Notes are  unconditionally  guaranteed  as to
principal,  interest and any other amounts due by Diamond  Cable  Communications
Plc.

         The Senior Notes are unsecured  senior  indebtedness of the Issuer.  At
June 30, 1998, the Company has approximately  (pound)758 million of indebtedness
outstanding,  including approximately (pound)146 million, (pound)240 million and
(pound)172  million in accreted  value of the 13 1/4% Senior  Discount Notes due
September  30,  2004,  the 11 3/4% Senior Notes due December 15, 2005 and the 10
3/4% Senior  Discount  Notes due February 15,  2007,  respectively.  Each of the
Sterling Senior Notes and the Dollar Senior Notes are ranked pari passu in right
of  payment  with  each  other  and  with  any  other  unsubordinated  unsecured
indebtedness  of the  Issuer.  The Issuer is a holding  company  which  conducts
substantially  all of its  business  through  subsidiaries,  all  of  which  are
wholly-owned.   Certain  intercompany   indebtedness  owed  to  the  Company  by
subsidiaries of the Issuer has been subordinated to the Senior Notes. The Senior
Notes  effectively rank junior to any indebtedness of the Issuer's  subsidiaries
to the extent of the assets of such subsidiaries and to any secured indebtedness
of the Issuer to the extent of the assets securing such indebtedness.
