SECTION 2.01.  FORM AND DATING.

     (a) General.

     The Initial Notes and the Trustee's  certificate of authentication shall be

writing.  Each  Note  shall be dated the date of its  authentication.  The Notes
shall be in  denominations  of 1,000  pounds  sterling  and  integral  multiples
thereof.  The terms  and  provisions  of the  Notes  set forth in  Exhibit A and

     (b) Global Notes.

     The Initial Notes are being offered and sold by the Company pursuant to the
Purchase Agreement.

     Initial  Notes  offered  and sold in  reliance  on  Regulation  S under the
Securities Act ("Regulation S"), as provided in the Purchase Agreement, shall be
issued  initially  in  the  form  of one  or  more  permanent  Global  Notes  in
definitive, fully registered form without interest coupons with the Global Notes
Legend  and  Restricted  Notes  Legend  set  forth  in  Exhibit  A  hereto  (the
"Regulation  S  Global  Note"),  which  shall  be  deposited  on  behalf  of the
purchasers of the Initial Notes represented thereby with the Trustee, at its New
York office, as custodian, for the Depositary, and registered in the name of the
Depositary  or the nominee of the  Depositary  for the  accounts  of  designated
agents holding on behalf of the Euroclear  System  ("Euroclear")  or Cedel Bank,
societe anonyme ("Cedel"), duly executed by the Company and authenticated by the
Trustee  as  hereinafter  provided.   The  aggregate  principal  amount  of  the
Regulation  S Global Note may from time to time be  increased  or  decreased  by
adjustments made on the records of the Trustee and the Depositary or its nominee
as hereinafter provided.

     Initial Notes offered and sold to Qualified  Institutional  Buyers ("QIBs")
in reliance on Rule 144A under the Securities Act ("Rule 144A"),  as provided in
the  Purchase  Agreement,  shall be issued  initially in the form of one or more
permanent  Global Notes in definitive,  fully  registered form without  interest
coupons with the Global Notes  Legend and  Restricted  Notes Legend set forth in
Exhibit A hereto ("Rule 144A Global  Note"),  which shall be deposited on behalf
of the purchasers of the Initial Notes represented  thereby with the Trustee, at
its New York office, as custodian for the Depositary, and registered in the name
of the Depositary or a nominee of the  Depositary,  duly executed by the Company
and  authenticated  by  the  Trustee  as  hereinafter  provided.  The  aggregate
principal amount of the Rule


                                       15
<PAGE>


144A Global Note may from time to time be increased or decreased by  adjustments
made  on the  records  of the  Trustee  and the  Depositary  or its  nominee  as
hereinafter provided.

     Upon consummation of the Registered  Exchange Offer, the Exchange Notes may
be issued in the form of one or more permanent Global Notes in definitive, fully
registered  form without  interest  coupons with the Global Notes Legend but not
the  Restricted  Notes Legend set forth in Exhibit A hereto,  registered  in the
name of the  Depositary  or a nominee of the  Depositary,  duly  executed by the
Company and authenticated by the Trustee as hereinafter provided.  The aggregate
principal  amount of such  Global  Notes may from time to time be  increased  or
decreased by  adjustments  made on the records of the Trustee and the Depositary
or its nominee as hereinafter provided.

     (c) Book-Entry Provisions.

     This Section  2.01(c) shall apply only to the Regulation S Global Note, the
Rule 144A Global Note and the  Exchange  Notes issued in the form of one or more
permanent Global Notes  (collectively,  the "Global Notes") deposited with or on
behalf of the Depositary.

     The Company shall execute and the Trustee  shall,  in accordance  with this
Section  2.01(c),  authenticate  and deliver  initially one or more Global Notes
that (a) shall be registered in the name of the  Depositary for such Global Note
or Global Notes or the nominee of such  Depositary and (b) shall be delivered by
the Trustee to such Depositary or pursuant to such Depositary's  instructions or
held by the Trustee as custodian for the Depositary.

     Members of, or participants in, the Depositary ("Agent Members") shall have
no rights  under this  Indenture  with  respect to any Global Note held on their
behalf by the Depositary or by the Trustee as the custodian of the Depositary or
under such Global Note, and the  Depositary  may be treated by the Company,  the
Trustee  and any agent of the Company or the  Trustee as the  absolute  owner of
such Global Note for all purposes  whatsoever.  Notwithstanding  the  foregoing,
nothing  herein  shall  prevent  the  Company,  the  Trustee or any agent of the
Company or the Trustee from giving effect to any written certification, proxy or
other  authorization  furnished  by the  Depositary  or impair,  as between  the
Depositary and its Agent Members,  the operation of customary  practices of such
Depositary  governing  the  exercise  of the rights of an owner of a  beneficial
interest in any Global Note.

     Without  limitation  of the  preceding  paragraph,  all  payments  to Agent
Members in respect of any Global  Note held by the  Depositary  (except  for the
account of Euroclear of Cedel) shall,  unless notice  requesting  payment in the
currency in which the Notes are  denominated  is given by such Agent  Members in
accordance with applicable procedures of the Depositary, be made in U.S. Dollars
in accordance with applicable procedures of the Depositary, if and to the extent
such payment is required by such procedures and provided that  arrangements  for
the  conversion  of  payments by the Company in respect of such Global Note into
U.S.  Dollars are in form and substance  acceptable to the Paying Agent or other
party to such  conversion  (which may but need not be an affiliate of the Paying
Agent),  including receipt of documentation  satisfactory to the Paying Agent or
such other  party and payment of any  currency  conversion  fee  assessed by the
Paying Agent or such other party at the expense of such Agent  Members.  Nothing
in such procedures or arrangements shall affect the Company's obligation to pay,
and any  Holder's  right to receive,  payment in the currency in which the Notes
are denominated,  or the right of a Holder of a beneficial  interest in a Global
Note to receive a Note in certificated form as contemplated by Section 2.01(d).


                                       16

     (d) Certificated Notes.

     In  addition  to the  provisions  of  Section  2.10,  owners of  beneficial
interests  in  Global  Notes  may,  upon  request  to  the  Trustee,  receive  a
certificated  Initial  Note,  which  certificated  Initial  Note  shall bear the
Restricted Notes Legend set forth in Exhibit A hereto ("Restricted Notes").

     After  a  transfer  of  any  Initial   Notes   during  the  period  of  the
effectiveness  of a Shelf  Registration  Statement  with  respect to the Initial
Notes and pursuant  thereto,  all  requirements  for Restricted Notes Legends on
such Initial Note will cease to apply, and a certificated Initial Note without a
Restricted  Notes Legend will be available to the Holder of such Initial  Notes.
Upon the consummation of a Registered Exchange Offer with respect to the Initial
Notes  pursuant to which Holders of Initial Notes are offered  Exchange Notes in
exchange for their Initial Notes, certificated Initial Notes with the Restricted
Notes  Legend set forth in Exhibit A hereto will be available to Holders of such
Initial Notes that do not exchange  their Initial  Notes,  and Exchange Notes in
certificated  form  without the  Restricted  Notes Legend set forth in Exhibit A
hereto will be  available to Holders that  exchange  such Initial  Notes in such
Registered Exchange Offer.

SECTION 2.02.  EXECUTION AND AUTHENTICATION.

     Two  Officers  shall sign the Notes for the Company by manual or  facsimile
signature.

     If an Officer  whose  signature is on a Note no longer holds that office at
the time the Note is authenticated, the Note shall nevertheless be valid.

     A Note shall not be valid until authenticated by the manual signature of an
authorized  officer of the Trustee.  The signature shall be conclusive  evidence
that the Note has been authenticated under this Indenture.

     The  Trustee  shall,  upon a  written  order of the  Company  signed by two
Officers,  authenticate  (1) Initial Notes for original issue up to an aggregate
principal  amount  stated in  paragraph 6 of the Initial  Notes and (2) Exchange
Notes  for  issue  only  in  a  Registered  Exchange  Offer,   pursuant  to  the
Registration  Rights  Agreement,  in  exchange  for  Initial  Notes  for a  like
principal  amount.  The aggregate  principal amount of Notes  outstanding at any
time shall not exceed the amount set forth herein, except as provided in Section
2.07.

     The Trustee may appoint an  authenticating  agent acceptable to the Company
to authenticate  Notes. An authenticating  agent may authenticate Notes whenever
the Trustee may do so. Each reference in this Indenture to authentication by the
Trustee includes  authentication by such agent. An authenticating  agent has the
same rights as an Agent to deal with Holders, the Company or an Affiliate.

SECTION 2.03.  REGISTRAR AND PAYING AGENT.

     The Company shall  maintain in the Borough of Manhattan,  City of New York,
State of New York and, as long as the Notes are listed on the  Luxembourg  Stock
Exchange,  in  Luxembourg,  (i)  offices  or  agencies  where  the  Notes may be
presented for  registration of transfer or for exchange  ("Registrar")  and (ii)
offices  or  agencies  where the Notes may be  presented  for  payment  ("Paying
Agent").  The Company  initially  designates the Trustee at its corporate  trust
offices in the Borough of Manhattan,  City of New York, State of New York to act
as principal  Registrar and Paying Agent and Banque  Internationale a Luxembourg
S.A. to act as a Registrar and Paying Agent.  Until otherwise  designated by


                                       17
<PAGE>


the  Company,  the Company  shall also  provide a Registrar  and Paying Agent in
London,  England at the offices of the Trustee maintained for that purpose.  The
Paying Agent  located at the offices of the Trustee in London,  England shall be
the principal Paying Agent. The principal Registrar shall keep a register of the
Notes and of their  transfer and  exchange.  The Company may appoint one or more
co-registrars  and one or more additional  paying agents in such other locations
as it shall determine.  The term  "Registrar"  includes any co-registrar and the
term "Paying Agent" includes any additional paying agent. The Company may change
any Paying Agent or Registrar  without  prior notice to any Holder.  The Company
shall  notify the  Trustee  of the name and  address of any Agent not a party to
this  Indenture.  If the Company fails to appoint or maintain  another entity as
Registrar or Paying Agent,  the Trustee shall act as such. The Company or any of
its Affiliates may act as Paying Agent or Registrar.

SECTION 2.04.  PAYING AGENT TO HOLD MONEY IN TRUST.

     The Company shall require each Paying Agent other than the Trustee to agree
in writing  that the Paying  Agent will hold in trust for the benefit of Holders
or the Trustee all money held by the Paying  Agent for the payment of  principal
or  interest  on the Notes,  and will  notify the  Trustee of any default by the
Company  in making  any such  payment.  While any such  default  continues,  the
Trustee  may  require a Paying  Agent to pay all money held by it to the Trustee
and to  account  for any money  disbursed  by it.  The  Company  at any time may
require a Paying Agent to pay all money held by it to the Trustee.  Upon payment
over to the Trustee, the Paying Agent (if other than the Company or an Affiliate
of the Company) shall have no further liability for the money. If the Company or
an Affiliate of the Company acts as Paying Agent, it shall segregate and hold in
a separate  trust fund for the  benefit of the  Holders  all money held by it as
Paying Agent.

SECTION 2.05.  HOLDER LISTS.

     The  Trustee  shall  preserve  in  as  current  a  form  as  is  reasonably
practicable  the most recent list  available to it of the names and addresses of
Holders.  If the Trustee is not the Registrar,  the Company shall furnish to the
Trustee on or before each  interest  payment date and at such other times as the
Trustee  may  request  in writing a list in such form and as of such date as the
Trustee may reasonably require of the names and addresses of Holders.

SECTION 2.06.  TRANSFER AND EXCHANGE.

     Where Notes are presented to the Registrar or a co-registrar with a request
to  register a transfer  or to exchange  them for an equal  principal  amount of
Notes of other denominations,  the Registrar shall register the transfer or make
the  exchange  if its  requirements  for such  transactions  are met.  To permit
registrations  of  transfers  and  exchanges,  the  Company  shall issue and the
Trustee shall authenticate Notes at the Registrar's  request.  No service charge
shall be made for any  registration of transfer or exchange (except as otherwise
expressly  permitted  herein),  but the  Company  may  require  payment of a sum
sufficient to cover any transfer tax or similar  governmental  charge payable in
connection  therewith (other than any such transfer tax or similar  governmental
charge payable upon exchanges pursuant to Sections 2.10, 3.06 or 9.05 hereof).

     The Company shall not be required (i) to issue, register the transfer of or
exchange  any Note for a period  beginning  at the  opening of  business 15 days
before the day of any  selection  of Notes to be  redeemed  under  Section  3.02
hereof and ending at the close of business on the day of  selection,  or (ii) to


                                       18
<PAGE>


register the transfer,  or exchange,  of any Note so selected for  redemption in
whole or in part,  except the  unredeemed  portion of any Note being redeemed in
part.

     (a)  Notwithstanding  any  provision to the contrary  herein,  so long as a
Global Note remains  outstanding  and is held by or on behalf of the Depositary,
transfers of a Global Note, in whole or in part, or of any  beneficial  interest
therein,  shall only be made in accordance with Section 2.01(b) and this Section
2.06(a);  provided,  however,  that beneficial interests in a Global Note may be
transferred  to Persons who take  delivery  thereof in the form of a  beneficial
interest in the same Global Note in  accordance  with the transfer  restrictions
set forth in the  Restricted  Notes  Legend  and under the  heading  "Notice  to
Investors" in the Company's Offering Memorandum dated March 6, 1998.

          (i) Except for transfers or exchanges made in accordance  with clauses
     (ii) through (iv) of this Section 2.06(a), transfers of a Global Note shall
     be limited to transfers of such Global Note in whole,  but not in part,  to
     nominees of the  Depositary  or to a successor  of the  Depositary  or such
     successor's nominee.

          (ii) Rule 144A Global Note to Regulation S Global Note. If an owner of
     a  beneficial  interest  in the Rule 144A Global  Note  deposited  with the
     Depositary  or the Trustee as custodian  for the  Depositary  wishes at any
     time to transfer its interest in such Rule 144A Global Note to a Person who
     is  required  to take  delivery  thereof in the form of an  interest in the
     Regulation  S Global  Note,  such  owner  may,  subject  to the  rules  and
     procedures  of the  Depositary,  exchange  or cause  the  exchange  of such
     interest for an equivalent  beneficial  interest in the Regulation S Global
     Notes. Upon receipt by the principal Registrar of (1) instructions given in
     accordance with the Depositary's  procedures from an Agent Member directing
     the  principal  Registrar  to credit or cause to be  credited a  beneficial
     interest  in the  Regulation  S  Global  Note  in an  amount  equal  to the
     beneficial  interest in the Rule 144A Global  Note to be  exchanged,  (2) a
     written  order  given  in  accordance  with  the  Depositary's   procedures
     containing  information regarding the participant account of the Depositary
     and the  Euroclear or Cedel  account to be credited  with such increase and
     (3) a  certificate  in the form of Exhibit C attached  hereto  given by the
     Holder of such  beneficial  interest,  then the principal  Registrar  shall
     instruct  the  Depositary  to reduce or cause to be reduced  the  principal
     amount  of the  Rule  144A  Global  Note  and to  increase  or  cause to be
     increased  the  principal  amount of the  Regulation  S Global  Note by the
     aggregate  principal  amount of the  beneficial  interest  in the Rule 144A
     Global Note equal to the  beneficial  interest in the  Regulation  S Global
     Note to be exchanged or  transferred,  to credit or cause to be credited to
     the  account of the Person  specified  in such  instructions  a  beneficial
     Interest  in the  Regulation  S Global Note equal to the  reduction  in the
     principal  amount of the Rule 144A  Global Note and to debit or cause to be
     debited from the account of the Person making such exchange or transfer the
     beneficial interest in the Rule 144A Global Note that is being exchanged or
     transferred.

          (iii)  Regulation S Global Note to Rule 144A Global Note.  If an owner
     of a beneficial interest in the Regulation S Global Note deposited with the
     Depositary  or with the Trustee as custodian for the  Depositary  wishes at
     any time to transfer  its  interest in such  Regulation  S Global Note to a
     Person who is required to take delivery  thereof in the form of an interest
     in the Rule 144A Global  Note,  such  Holder may,  subject to the rules and
     procedures of Euroclear or Cedel,  as the case may be, and the  Depositary,
     exchange  or  cause  the  exchange  of  such  interest  for  an  equivalent
     beneficial  interest  in the Rule


                                       19
<PAGE>


     144A  Global  Note.  Upon  receipt  by  the  principal   Registrar  of  (1)
     instructions  from Euroclear or Cedel,  if applicable,  and the Depositary,
     directing  the  principal  Registrar  to credit or cause to be  credited  a
     beneficial  interest in the Rule 144A  Global Note equal to the  beneficial
     interest in the  Regulation S Global Note to be  exchanged or  transferred,
     such instructions to contain information  regarding the participant account
     with the Depositary to be credited with such increase,  (2) a written order
     given in accordance with the Depositary's procedures containing information
     regarding the  participant  account of the Depositary and (3) a certificate
     in the  form of  Exhibit  D  attached  hereto  given  by the  owner of such
     beneficial interest, then Euroclear or Cedel or the principal Registrar, as
     the case may be,  will  instruct  the  Depositary  to reduce or cause to be
     reduced  the  Regulation  S  Global  Note  and to  increase  or cause to be
     increased  the  principal  amount  of the  Rule  144A  Global  Note  by the
     aggregate  principal amount of the beneficial  interest in the Regulation S
     Global Note to be exchanged or  transferred,  and the  principal  Registrar
     shall instruct the Depositary,  concurrently with such reduction, to credit
     or cause to be  credited  to the  account of the Person  specified  in such
     instructions  a  beneficial  interest in the Rule 144A Global Note equal to
     the reduction in the principal  amount of the  Regulation S Global Note and
     to debit or cause to be debited from the account of the Person  making such
     exchange or transfer  the  beneficial  interest in the  Regulation S Global
     Note that is being exchanged or transferred.

          (iv)  Global  Note to  Restricted  Note.  If an owner of a  beneficial
     interest in a Global Note deposited with the Depositary or with the Trustee
     as custodian for the Depositary wishes at any time to transfer its interest
     in such Global Note to a Person who is required to take delivery thereof in
     the form of a  Restricted  Note,  such owner may,  subject to the rules and
     procedures of Euroclear or Cedel, if applicable, and the Depositary,  cause
     the  exchange  of such  interest  for one or more  Restricted  Notes of any
     authorized   denomination  or  denominations  and  of  the  same  aggregate
     principal  amount.   Upon  receipt  by  the  principal   Registrar  of  (1)
     instructions  from Euroclear or Cedel,  if  applicable,  and the Depositary
     directing the principal  Registrar to authenticate  and deliver one or more
     Restricted  Notes of the same aggregate  principal amount as the beneficial
     interest in the Global Note to be exchanged,  such  instructions to contain
     the  name  or  names  of the  designated  transferee  or  transferees,  the
     authorized  denomination or  denominations of the Restricted Notes to be so
     issued and appropriate delivery instructions, (2) a certificate in the form
     of Exhibit E attached hereto given by the owner of such beneficial interest
     to the effect set forth therein, (3) a certificate in the form of Exhibit F
     attached  hereto given by the Person  acquiring  the  Restricted  Notes for
     which such interest is being  exchanged,  to the effect set forth  therein,
     and (4) such other  certifications,  legal opinions or other information as
     the Company may  reasonably  require to confirm that such transfer is being
     made pursuant to an exemption from, or in a transaction not subject to, the
     registration  requirements  of the Securities Act, then Euroclear or Cedel,
     if  applicable,  or the  principal  Registrar,  as the  case  may be,  will
     instruct the  Depositary  to reduce or cause to be reduced such Global Note
     by the aggregate  principal amount of the beneficial interest therein to be
     exchanged  and to  debit or cause to be  debited  from the  account  of the
     Person making such transfer the beneficial interest in the Global Note that
     is being  transferred,  and concurrently  with such reduction and debit the
     Company shall execute,  and the Trustee shall authenticate and deliver, one
     or  more  Restricted  Notes  of the  same  aggregate  principal  amount  in
     accordance with the instructions referred to above.


                                       20

          (v)  Restricted  Note to Restricted  Note. If a Holder of a Restricted
     Note wishes at any time to transfer such Restricted Note to a Person who is
     required to take delivery  thereof in the form of a Restricted  Note,  such
     Holder may, subject to the restrictions on transfer set forth herein and in
     such Restricted Note, cause the exchange of such Restricted Note for one or
     more Restricted Notes of any authorized  denomination or denominations  and
     of the same  aggregate  principal  amount.  Upon  receipt by the  principal
     Registrar of (1) such Restricted  Note,  duly endorsed as provided  herein,
     (2)  instructions  from such Holder  directing the  principal  Registrar to
     authenticate and deliver one or more Restricted Notes of the same aggregate
     principal amount as the Restricted Note to be exchanged,  such instructions
     to contain the name or  authorized  denomination  or  denominations  of the
     Restricted Notes to be so issued and appropriate delivery instructions, (3)
     a certificate from the Holder of the Restricted Note to be exchanged in the
     form of Exhibit E attached hereto, (4) a certificate in the form of Exhibit
     F attached  hereto given by the Person  acquiring the Restricted  Notes for
     which such interest is being  exchanged,  to the effect set forth  therein,
     and (5) such other  certifications,  legal opinions or other information as
     the Company may  reasonably  require to confirm that such transfer is being
     made pursuant to an exemption from, or in a transaction not subject to, the
     registration  requirements  of the Securities Act, then the Registrar shall
     cancel  or cause  to be  canceled  such  Restricted  Note and  concurrently
     therewith,  the Company shall execute,  and the Trustee shall  authenticate
     and deliver,  one or more Restricted Notes of the same aggregate  principal
     amount, in accordance with the instructions referred to above.

          (vi) Other  Exchanges.  In the event that a  beneficial  interest in a
     Global Note is exchanged for Notes in definitive  registered  form pursuant
     to  Section  2.10,  prior  to the  effectiveness  of a  Shelf  Registration
     Statement  with respect to such Notes,  such Notes may be exchanged only in
     accordance  with such procedures as are  substantially  consistent with the
     provisions of clauses (ii) through (v) above  (including the  certification
     requirements  intended to ensure that such transfers comply with Rule 144A,
     Rule 144,  Regulation S or any other available exemption from registration,
     as the case may be) and such other  procedures  as may from time to time be
     adopted by the Company.

          (vii) Restricted  Period.  Prior to the termination of the "restricted
     period" (as defined in  Regulation  S) with  respect to the issuance of the
     Notes,  transfers  of  interests  in the  Regulation S Global Note to "U.S.
     Persons" (as defined in Regulation S) shall be limited to transfers to QIBs
     made pursuant to the provisions of Sections 2.06(a)(iii). The Company shall
     advise the Trustee as to the  termination of the restricted  period and the
     Trustee may rely conclusively thereon.

          (viii)  Regulation  S Global Note to  Certificated  Note.  Upon proper
     presentment  to the Trustee of a certificate  substantially  in the form of
     Exhibit G hereto and subject to the rules and  procedures of the Depositary
     or its direct or indirect  participants,  including Euroclear and Cedel, an
     interest in a Regulation S Global Note may be exchanged for a  certificated
     Restricted  Note. At any time following  consummation of the Exchange Offer
     pursuant  to  the  Registration   Rights  Agreement   (provided  that  such
     consummation  is after  the  expiration  of the  40-day  restricted  period
     provided  for in Rule  903 of  Regulation  S),  such  exchange  may be made
     without presentment of the certificate in substantially the form of Exhibit
     G by any Holder who


                                       21
<PAGE>


     certifies  to the  Trustee  that  such  Holder  would  have  been  able  to
     participate  in such  Exchange  Offer and  resell  Exchange  Notes  without
     delivery of a prospectus under applicable rules and  interpretations of the
     Commission,  and such  certificated Note shall be free from any restriction
     on transfer  (other than such as are solely  attributable  to any  holder's
     status).

     (b)  Except  in  connection  with a  Registered  Exchange  Offer or a Shelf
Registration  Statement  contemplated by and in accordance with the terms of the
Registration  Rights  Agreement,  if Initial Notes are issued upon the transfer,
exchange or  replacement  of Initial  Notes  bearing the  Restricted  Securities
Legend  set forth in Exhibit A hereto,  or if a request  is made to remove  such
Restricted Notes Legend on Initial Notes, the Initial Notes so issued shall bear
the  Restricted  Notes  Legend,  or the  Restricted  Notes  Legend  shall not be
removed,  as the case may be,  unless  there is  delivered  to the Company  such
satisfactory  evidence,  which may  include an opinion  of counsel  licensed  to
practice  law in the State of New York,  as may be  reasonably  required  by the
Company,  that  neither the legend nor the  restrictions  on transfer  set forth
therein are required to ensure that transfers thereof comply with the provisions
of Rule 144A,  Rule 144,  Regulation  S or any other  available  exemption  from
registration under the Securities Act or, with respect to Restricted Notes, that
such  Notes  are not  "restricted"  within  the  meaning  of Rule 144  under the
Securities Act. Upon provision of such satisfactory  evidence,  the Trustee,  at
the direction of the Company,  shall authenticate and deliver Initial Notes that
do not bear the legend.

     (c) Neither the Company nor the Trustee shall have any  responsibility  for
any actions taken or not taken by the  Depositary  and the Company shall have no
responsibility  for any  actions  taken or not taken by the  Trustee as agent or
custodian of the Depositary.

SECTION 2.07.  REPLACEMENT NOTES.

     If the Holder of a Note  claims that the Note has been lost,  destroyed  or
wrongfully taken or if such Note is mutilated and is surrendered to the Trustee,
the Company shall issue and the Trustee shall authenticate a replacement Note if
the Trustee's and the Company's requirements are met. If required by the Trustee
or the Company,  an indemnity bond must be sufficient in the judgment of both to
protect the Company, the Trustee, any Agent or any authenticating agent from any
loss which any of them may suffer if a Note is replaced.  The Company may charge
for its expenses in replacing a Note.

     In case any such mutilated, destroyed, lost or stolen Note has become or is
about to become due and  payable,  or is about to be  purchased  by the  Company
pursuant to Article III hereof,  the Company in its discretion  may,  instead of
issuing a new Note, pay or purchase such Note, as the case may be.

     Every replacement Note is an additional obligation of the Company and shall
be entitled to all of the benefits of this Indenture equally and proportionately
with all other Notes duly issued hereunder.

SECTION 2.08.  OUTSTANDING NOTES.

     The Notes  outstanding at any time are all the Notes  authenticated  by the
Trustee except for those canceled by it, those delivered to it for cancellation,
and those described in this Section as not outstanding.


                                       22
<PAGE>


     If a Note is replaced,  paid or purchased  pursuant to Section 2.07 hereof,
it ceases to be outstanding unless the Trustee receives proof satisfactory to it
that the replaced, paid or purchased Note is held by a bona fide purchaser.

     If the principal  amount of any Note is considered  paid under Section 4.01
hereof, it ceases to be outstanding and interest on it ceases to accrue.

     Except as set forth in  Section  2.09  hereof,  a Note does not cease to be
outstanding because the Company or an Affiliate of the Company holds the Note.

SECTION 2.09.  TREASURY NOTES.

     In  determining  whether the Holders of the  required  principal  amount of
Notes have  concurred in any  direction,  waiver or consent,  Notes owned by the
Company or an Affiliate of the Company  shall be  considered  as though they are
not outstanding, except that for the purposes of determining whether the Trustee
shall be protected  in relying on any such  direction,  waiver or consent,  only
Notes that the Trustee knows are so owned shall be so disregarded.

SECTION 2.10.  TEMPORARY NOTES; GLOBAL NOTES.

     (a) Until definitive Notes are ready for delivery,  the Company may prepare
and the Trustee shall  authenticate  temporary  Notes.  Temporary Notes shall be
substantially  in the form of definitive  Notes but may have variations that the
Company considers  appropriate for temporary Notes.  Without unreasonable delay,
the Company shall prepare and the Trustee shall authenticate definitive Notes in
exchange for temporary  Notes.  Holders of temporary  Notes shall be entitled to
all of the benefits of this Indenture.

     (b) A Global  Note  deposited  with the  Depositary  or with the Trustee as
custodian for the  Depositary  pursuant to Section 2.01 shall be  transferred to
the  beneficial  owners  thereof  in the  form  of  certificated  Notes  only in
accordance with Section  2.01(d) or if such transfer  complies with Section 2.06
and (i) the  Depositary  notifies  the Company that it is unwilling or unable to
continue as  Depositary  for such Global Note or if at any time such  Depositary
ceases  to be a  "clearing  agency"  registered  under  the  Exchange  Act and a
successor  depositary  is not  appointed  by the Company  within 90 days of such
notice, or (ii) an Event of Default has occurred and is continuing.

     (c) Any Global Note that is transferable  to the beneficial  owners thereof
in the form of  certificated  Notes pursuant to Section  2.01(d) or this Section
2.10 shall be surrendered by the Depositary to the Trustee to be so transferred,
in whole or from time to time in part,  without  charge,  and the Trustee  shall
authenticate  and  deliver,  upon such  transfer of each  portion of such Global
Note,  an equal  aggregate  principal  amount  of  Initial  Notes of  authorized
denominations  in the form of certificated  Notes.  Any portion of a Global Note
transferred  pursuant  to this  Section  shall be  executed,  authenticated  and
delivered  only in  denominations  of 1,000  pounds  sterling  and any  integral
multiple  thereof and registered in such names as the  Depositary  shall direct.
Any Initial Note in the form of certificated  Notes delivered in exchange for an
interest in the Global  Notes  shall,  except as  otherwise  provided by Section
2.06(b) bear the Restricted Notes Legend set forth in Exhibit A hereto.


                                       23
<PAGE>


     (d) The registered  Holder of a Global Note may grant proxies and otherwise
authorize  any  Person,  including  Agent  Members  and  Persons  that  may hold
interests  through Agent Members,  to take any action which a Holder is entitled
to take under this Indenture or the Notes.

     (e) In the event of the  occurrence  of either of the events  specified  in
Section  2.10(b),  the Company  will  promptly  make  available to the Trustee a
reasonable  supply of certificated  Notes in definitive,  fully  registered form
without interest coupons.

SECTION 2.11.  CANCELLATION.

     The Company at any time may deliver Notes to the Trustee for  cancellation.
The  Registrar  and  Paying  Agent  shall  forward  to  the  Trustee  any  Notes
surrendered  to them for  registration  of  transfer,  exchange or payment.  The
Trustee  shall  promptly  cancel  all  Notes  surrendered  for  registration  of
transfer,  exchange,  payment,  replacement or cancellation and shall dispose of
canceled  Notes as the Company  directs.  The Company may not issue new Notes to
replace  Notes that it has paid or that have been  delivered  to the Trustee for
cancellation.

SECTION 2.12.  DEFAULTED INTEREST.

     If the Company  fails to make a payment of interest on the Notes,  it shall
pay such defaulted interest plus any interest payable on the defaulted interest,
in any lawful manner. It may pay such defaulted interest, plus any such interest
payable on it, to the  Persons who are Holders on a  subsequent  special  record
date. The Company shall fix any such record date and payment date, provided that
no such record date shall be less than 10 days prior to the related payment date
for such defaulted  interest.  At least 15 days before any such record date, the
Company shall mail to Holders a notice that states the special  record date, the
related payment date and amount of such interest to be paid.


                                  ARTICLE III.
                                   REDEMPTION

SECTION 3.01.  NOTICES TO TRUSTEE.

provisions  of the Notes and Section 3.07 hereof or pursuant to the Optional Tax
Redemption  provision of the Notes (Section 8 of the Initial Notes and Section 7
of the Exchange  Notes),  it shall notify the Trustee of the redemption date and
the principal amount of Notes to be redeemed, and in connection with an Optional
Tax Redemption as provided in the Notes,  such notice shall be accompanied by an
Officers'  Certificate  to the effect  that the  conditions  to such  redemption
contained  herein have been  complied  with.  The Company shall give each notice
provided for in this Section  3.01 at least 50 days before the  redemption  date
(unless a shorter notice period shall be satisfactory to the Trustee).

SECTION 3.02.  SELECTION OF NOTES TO BE REDEEMED.

     If less than all of the Notes are to be redeemed at any time,  selection of
Notes  shall be made by the  Trustee  on a pro rata basis or by lot or by method
that  complies  with the  requirements  of any  exchange  on which the Notes are
listed and that the Trustee  considers  fair and  appropriate,  provided that no
Notes of 1,000  pounds  sterling or less shall be redeemed in part.  The Trustee
shall make the  selection not more than 60 days and not less than 30 days before
the redemption date from Notes outstanding not previously called for redemption.
Notes  and  portions  of Notes  selected  shall be in  amounts  of 1,000  pounds
sterling or integral


                                       24
<PAGE>


multiples of 1,000 pounds  sterling.  Provisions of this Indenture that apply to
Notes  called  for  redemption  also  apply  to  portions  of Notes  called  for

portions of Notes to be called for redemption.

SECTION 3.03.  NOTICE OF REDEMPTION.

     At least 30 days but not more than 60 days before a  redemption  date,  the
Company  shall mail,  by first class mail, a notice of redemption to each Holder
whose Notes are to be  redeemed  at its  registered  address.  The notice  shall
identify the Notes to be redeemed and shall state:

     (a) the redemption date;

     (b) the redemption price;

     (c) if any  Note  is to be  redeemed  in  part  only,  the  portion  of the
principal  amount thereof  redeemed,  and that,  after the redemption date, upon
surrender of such Note, a new Note in principal  amount equal to the  unredeemed
portion  thereof  shall  be  issued  in the  name  of the  Holder  thereof  upon
cancellation of the original Note;

     (d) the name and address of the Paying Agent;

     (e) that Notes  called for  redemption  must be  surrendered  to the Paying
Agent to collect the redemption price plus accrued interest;

     (f) that  interest on Notes called for  redemption  ceases to accrue on and
after the redemption date; and

     (g) the  paragraph  of the Notes  pursuant  to which the Notes  called  for
redemption are being redeemed.

     At the  Company's  request,  the Trustee shall give notice of redemption in
the  Company's  name and at its expense;  provided  that the Company  shall have
delivered  to the Trustee,  at least 45 days prior to the  redemption  date,  an
Officers'  Certificate  requesting that the Trustee give such notice and setting
forth the information to be stated in such notice,  as provided in the preceding
paragraph.

SECTION 3.04.  EFFECT OF NOTICE OF REDEMPTION.

     Once notice of redemption is mailed in accordance with Section 3.03 hereof,
Notes called for redemption become due and payable on the redemption date at the
price set forth in the Note. A notice of redemption may not be conditional.

SECTION 3.05.  DEPOSIT OF REDEMPTION PRICE.

     On or before the  redemption  date,  the  Company  shall  deposit  with the
Trustee or with the Paying Agent money sufficient to pay the redemption price of
and accrued  interest  on all Notes to be redeemed on that date.  The Trustee or
the Paying  Agent shall  return to the Company any money not  required  for that
purpose.


                                       25
<PAGE>


SECTION 3.06.  NOTES REDEEMED IN PART.

     Upon  surrender of a Note that is redeemed in part, the Company shall issue
and the Trustee shall  authenticate for the Holder at the expense of the Company
a new Note  equal in  principal  amount to the  unredeemed  portion  of the Note
surrendered.

SECTION 3.07.  OPTIONAL REDEMPTION AND OPTIONAL TAX REDEMPTION.

     The Company may redeem all or any portion of the Notes,  upon the terms and
at the  redemption  prices set forth in each of the Notes.  The Company may also
redeem all of the Notes in accordance with the Optional Tax Redemption provision
of the Notes  (Section  8 of the  Initial  Notes and  Section 7 of the  Exchange
Notes).  Any redemption  pursuant to this Section 3.07 shall be made pursuant to
the provisions of Section 3.01 through 3.06 hereof.

SECTION 3.08.  MANDATORY REDEMPTION

     The Company  shall not be required to make  mandatory  redemption  payments
with respect to the Notes.

SECTION 3.09.  ASSET SALE OFFER AND PURCHASE OFFER.

     (a) In the event  that,  pursuant  to  Sections  4.10 or 4.13  hereof,  the
Company  shall  commence an offer to all Holders of the Notes to purchase  Notes
(the "Asset Sale  Offer" or  "Purchase  Offer"),  the Company  shall  follow the
procedures in this Section 3.09.

     (b) The Asset Sale Offer or the Purchase  Offer,  as the case may be, shall
remain open for a period specified by the Company which shall be no less than 30
calendar days and no more than 40 calendar days following its commencement  (the
"Commencement  Date") (as  determined  in  accordance  with Section 4.10 or 4.13
hereof,  as the case may be),  except  to the  extent  that a longer  period  is
required by applicable  law (the "Tender  Period").  Upon the  expiration of the
Tender Period (the  "Purchase  Date"),  the Company shall purchase the principal
amount of Notes required to be purchased pursuant to Section 4.10 or 4.13 hereof
(the "Offer  Amount") or, if less than the Offer Amount has been  tendered,  all
Notes tendered in response to the Asset Sale Offer or the Purchase Offer, as the
case may be.

     (c) If the Purchase Date is on or after an interest payment record date and
on or before the related  interest  payment date, any accrued  interest shall be
paid to the Person in whose name a Note is  registered  at the close of business
on such record date,  and no additional  interest will be payable to Holders who
tender Notes pursuant to the Asset Sale Offer or the Purchase Offer, as the case
may be.

     (d) The Company  shall  provide  the Trustee  with notice of the Asset Sale
Offer or the  Purchase  Offer,  as the case may be, at least 10 days  before the
Commencement Date.

     (e) On or before the Commencement  Date, the Company or the Trustee (at the
expense of the Company) shall send, by first class mail, a notice to each of the
Holders,  which shall  govern the terms of the Asset Sale Offer or the  Purchase
Offer and shall state:

          (i) that the Asset  Sale  Offer or the  Purchase  Offer is being  made
     pursuant to this  Section  3.09 and, as  applicable,  Section  4.10 or 4.13
     hereof and the length of time the Asset  Sale Offer or the  Purchase  Offer
     will remain open;


                                       26
<PAGE>


          (ii) Offer  Amount,  the purchase  price (as  determined in accordance
     with Section 4.10 or 4.13 hereof) and the Purchase Date, and in the case of
     a Purchase  Offer made  pursuant  to Section  4.13  hereof,  that all Notes
     tendered will be accepted for payment;

          (iii) that any Note or portion  thereof not  tendered or accepted  for
     payment will continue to accrue interest;

          (iv) that,  unless the Company defaults in the payment of the purchase
     price,  any Note or portion  thereof  accepted for payment  pursuant to the
     Asset Sale Offer or the Purchase Offer will cease to accrue  interest after
     the Purchase Date;

          (v) that Holders electing to have a Note or portion thereof  purchased
     pursuant  to any Asset Sale Offer or  Purchase  Offer will be  required  to
     surrender  the  Note,  with the form  entitled  "Option  of Holder to Elect
     Purchase"  on the  reverse  of  the  Note  completed,  to  the  Company,  a
     depositary,  if appointed by the Company,  or a Paying Agent at the address
     specified  in the  notice  prior to the  close  of  business  on the  third
     Business Day preceding the Purchase Date;

          (vi) that Holders will be entitled to withdraw  their  election if the
     Company,  depositary or Paying  Agent,  as the case may be,  receives,  not
     later than the close of business on the second  Business Day  preceding the
     Purchase Date, or such longer period as may be required by law, a letter or
     a telegram,  telex or facsimile transmission (receipt of which is confirmed
     and promptly  followed by a letter)  setting  forth the name of the Holder,
     the principal  amount of the Note or portion  thereof the Holder  delivered
     for purchase and a statement that such Holder is  withdrawing  his election
     to have the Note or portion thereof purchased;

          (vii) that, if the aggregate  principal amount of Notes surrendered by
     Holders  exceeds the Offer Amount (as defined in Section 4.10 hereof),  the
     Trustee will select the Notes to be purchased  pro rata or by a method that
     complies  with the  requirements  of any  exchange  on which  the Notes are
     listed  and that the  Trustee  considers  fair and  appropriate  with  such
     adjustments as may be deemed  appropriate by the Company so that only Notes
     in denominations of 1,000 pounds sterling,  or integral  multiples thereof,
     shall be purchased; and

          (viii) that Holders  whose Notes were  purchased  only in part will be
     issued new Notes equal in principal  amount to the  unpurchased  portion of
     the Notes surrendered.

     In addition,  the notice shall, to the extent  permitted by applicable law,
be  accompanied  by a copy of the  information  regarding  the  Company  and its
Subsidiaries  which is required  to be  contained  in the most recent  Quarterly
Report on Form 10-Q or Annual  Report  on Form  10-K  (including  any  financial
statements  or other  information  required to be included  or  incorporated  by
reference  therein)  and any  Reports  on Form 8-K filed  since the date of such
Quarterly  Report or Annual  Report (or would have been  required to file if the
Company remained a company  incorporated in the United States),  as the case may
be,  which the  Company  has filed (or would  have been  required  to file if it
remained a company  incorporated  in the United States) with the SEC on or prior
to the date of the  notice.  The  notice  shall

basis according to accreted value or principal  amount,  as the case may be, the
relevant  principal amount of the Notes and the relevant principal amount or the
accreted value, as the case may be, of any Other Qualified Notes  denominated in
a currency  other than United States  dollars will be notionally  converted into
United States dollars from the currency such Notes or Other  Qualified Notes are
denominated in (the "Base Currency");

          (i)  in the case of determining the maximum  principal amount of Notes
               and Other Qualified Notes that may be purchased out of the Excess
               Proceeds,  if any,  remaining after the  consummation of an Asset
               Sale Offer to holders of  Applicable  Notes,  at the noon  buying
               rate in the City of New York as certified for customs purposes by
               the Federal  Reserve Bank of New York for cable  transfers in the
               Base  Currency (the "Noon Buying Rate") on the Business Day which
               is 10 Business Days prior to the Commencement Date; and

          (ii) in the case of determining the allocation of the remaining Excess
               Proceeds if the aggregate  principal amount or accreted value, as
               the case may be, of Notes and Other Qualified  Notes  surrendered
               by holders in the Asset Sale Offer exceeds the  remaining  amount
               of  Excess  Proceeds,  at the  Noon  Buying  Rate  on the  second
               Business Day preceding the Purchase Date.

     (h) The Asset Sale Offer or the Purchase Offer shall be made by the Company
in  compliance  with all  applicable  provisions  of the  Exchange  Act, and all
applicable  tender offer rules  promulgated  thereunder,  and shall  include all
instructions  and  materials  necessary  to enable such  Holders to tender their

premium,  if any, and interest  shall be considered  paid on the date due if the
Paying Agent  (other than the Company or an  Affiliate of the Company)  holds on

then due.  To the extent  lawful,  the  Company  shall pay  interest  (including

SECTION 4.02.  REPORTS.

     Whether or not required by the rules and regulations of the SEC, so long as
any Notes are  outstanding,  the Company  shall file with the SEC and furnish to
the Trustee  and to the Holders of Notes,  all  quarterly  and annual  financial
information  required to be contained in a filing with the SEC on Forms 10-Q and

issuers in the event the Company becomes a corporation  organized under the laws
of the United Kingdom, the Netherlands, the Netherlands Antilles, Bermuda or the
Cayman Islands), including a "Management's Discussion and Analysis of Results of
Operations and Financial  Condition" and, with respect to the annual information
only, a report thereon by the Company's certified  independent  accountants,  in
each case,  in the form required by the rules and  regulations  of the SEC as in
effect on the Issuance Date. This Section 4.02 will apply  notwithstanding  that
the  Company  becomes  a  corporation  organized  under  the laws of the  United
Kingdom,  the  Netherlands,  the  Netherlands  Antilles,  Bermuda  or the Cayman
Islands.

SECTION 4.03.  COMPLIANCE CERTIFICATE.

     The Company shall  deliver to the Trustee,  within 90 days after the end of
each fiscal year of the Company, an Officers'  Certificate stating that a review
of the  activities  of the Company  and its  subsidiaries  during the  preceding
fiscal year has been made under the  supervision of the signing  Officers with a
view to  determining  whether  the  Company has kept,  observed,  performed  and
fulfilled its obligations  under, and complied with the covenants and conditions
contained  in, this  Indenture,  and further  stating,  as to each such  Officer
signing  such  certificate,  that to the best of his  knowledge  the Company has
kept,  observed,  performed and fulfilled each and every covenant,  and complied
with the  covenants  and  conditions  contained in this  Indenture and is not in
default in the  performance  or observance of any of the terms,  provisions  and
conditions  hereof  (or, if a Default or Event of Default  shall have  occurred,
describing  all  such  Defaults  or  Events  of  Default  of  which  he may have
knowledge)  and that to the best of his  knowledge  no event  has  occurred  and
remains in existence by reason of which  payments on account of the principal or
of interest, if any, on the Notes are prohibited.

     One of the Officers signing such Officers'  Certificate shall be either the
Company's principal executive officer,  principal financial officer or principal
accounting officer.


                                       29
<PAGE>


     The Company  will so long as any of the Notes are  outstanding,  deliver to
the Trustee, forthwith upon becoming aware of any Default or Event of Default an
Officers' Certificate specifying such Default or Event of Default.

     Immediately  upon the occurrence of any event giving rise to the accrual of
Special  Interest (as such term is defined in Exhibit A hereto) or the cessation
of such accrual,  the Company shall give the Trustee  notice  thereof and of the
event giving rise to such  accrual or cessation  (such notice to be contained in
an Officers' Certificate) and prior to receipt of such Officers' Certificate the
Trustee  shall be  entitled  to assume that no such  accrual  has  commenced  or
ceased, as the case may be.

SECTION 4.04.  STAY, EXTENSION AND USURY LAWS.

     The Company  covenants  (to the extent that it may  lawfully do so) that it
will not at any time insist upon,  plead, or in any manner  whatsoever  claim or
take the benefit or  advantage  of, any stay,  extension  or usury law  wherever
enacted,  now or at any time hereafter in force,  which may affect the covenants
or the  performance  of this  Indenture;  and the  Company (to the extent it may
lawfully do so) hereby  expressly  waives all benefit or  advantage  of any such
law, and covenants that it will not, by resort to any such law, hinder, delay or
impede the execution of any power herein granted to the Trustee, but will suffer
and  permit  the  execution  of every  such power as though no such law had been
enacted.

SECTION 4.05.  CORPORATE EXISTENCE.

     Subject to Article V hereof,  the  Company  will do or cause to be done all
things  necessary  to preserve  and keep in full force and effect its  corporate
existence and the corporate,  partnership or other  existence of each subsidiary
of the Company in accordance  with the  respective  organizational  documents of
each subsidiary and the rights (charter and statutory),  licenses and franchises
of the Company and its subsidiaries;  provided,  however, that the Company shall
not be  required  to  preserve  any such  right,  license or  franchise,  or the
corporate,  partnership or other  existence of any  subsidiary,  if the Board of
Directors shall determine that the  preservation  thereof is no longer desirable
in the conduct of the  business of the Company and its  subsidiaries  taken as a
whole and that the loss  thereof is not adverse in any  material  respect to the
Holders. The Company shall notify the Trustee in writing of any subsidiary which
qualifies  as a Material  Subsidiary  and is not  specified in clause (i) of the
definition thereof.

SECTION 4.06.  TAXES.

     The Company shall,  and shall cause each of its  subsidiaries to, pay prior
to  delinquency  all  taxes,  assessments  and  governmental  levies,  except as
contested in good faith and by appropriate proceedings.

SECTION 4.07.  LIMITATIONS ON LIENS.

     Neither the Company nor any of its Restricted Subsidiaries may, directly or
indirectly  create,  incur,  assume or suffer to exist any Lien on any asset now
owned or  hereafter  acquired,  or any income or profits  therefrom or assign or
convey any right to receive income therefrom, except:

     (a) Permitted Liens;

     (b) Liens securing  Indebtedness and related obligations to the extent such
Indebtedness  and related  obligations are permitted under Sections  4.08(b)(i),

Indebtedness permitted to be incurred under Section 4.08 hereof; and

     (d) Liens securing Refinancing  Indebtedness permitted to be incurred under
Section 4.08 hereof;  provided that the  Refinancing  Indebtedness so issued and
secured  by such Lien  shall not be  secured  by any  property  or assets of the
Company or any of its Restricted  Subsidiaries other than the property or assets
subject to the Liens securing such Indebtedness being refinanced.

SECTION 4.08.  INCURRENCE  OF INDEBTEDNESS AND ISSUANCE OF PREFERRED STOCK.

     (a) The  Company  shall not,  and shall not  permit  any of its  Restricted
Subsidiaries to, directly or indirectly,  create, incur, issue, assume, guaranty

issue  any  Disqualified  Stock  and  shall  not  permit  any of its  Restricted
Subsidiaries to issue any shares of preferred stock that is Disqualified  Stock;
provided,  however,  that the Company may incur  Indebtedness or issue shares of
Disqualified  Stock and any of its Restricted  Subsidiaries  may issue shares of
preferred  stock  that is  Disqualified  Stock if after  giving  effect  to such
issuance or incurrence on a pro forma basis,  the sum of (x) Indebtedness of the
Company  and its  Restricted  Subsidiaries,  on a  consolidated  basis,  (y) the
liquidation value of outstanding preferred stock of Restricted  Subsidiaries and
(z) the aggregate amount payable by the Company and its Restricted Subsidiaries,
on a consolidated  basis,  upon redemption of  Disqualified  Stock to the extent
such amount is not included in the  preceding  clause (y) shall be less than the
product of Annualized  Pro Forma EBITDA for the latest fiscal  quarter for which
internal financial  statements are available  immediately  preceding the date on
which such  additional  Indebtedness is incurred or such  Disqualified  Stock or
preferred  stock is issued  multiplied  by 7.0,  determined on a pro forma basis
(including a pro forma  application  of the net proceeds  therefrom),  as if the
additional  Indebtedness  had  been  incurred,  or  the  Disqualified  Stock  or
preferred  stock had been issued,  as the case may be, at the  beginning of such
quarter.

     (b) The foregoing limitations in Section 4.08(a) shall not apply to:

          (i) the  incurrence  by the Company or any  Restricted  Subsidiary  of

     working capital needs of a Cable Business  (including,  without limitation,
     payments made pursuant to any License),  the acquisition of Cable Assets or
     the Capital Stock of a Qualified Subsidiary;

          (iv)  the   incurrence  by  the  Company  or  any  of  its  Restricted

     provided,  however,  that (1) the  principal  amount  of,  and any  premium
     payable in respect of, such Refinancing  Indebtedness  shall not exceed the
     principal amount of Indebtedness so extended, refinanced, renewed, replaced
     or refunded (plus the amount of reasonable  expenses incurred in connection
     therewith);  (2) the  Refinancing  Indebtedness  shall  have (A) a Weighted
     Average Life to Maturity equal to or greater than the Weighted Average Life
     to  Maturity  of,  and (B) a stated  maturity  no  earlier  than the stated
     maturity of, the Indebtedness being extended, refinanced, renewed, replaced
     or refunded; and (3) the Refinancing  Indebtedness shall be subordinated in
     right of  payment  to the Notes as and to the  extent  of the  Indebtedness

     that  are  being  hedged  thereby,  and not for  speculation  and  that the

     on a pro rata  basis and on  substantially  identical  principal  financial
     terms;  provided,  however,  that if any such Restricted Subsidiary that is
     the payee of any such Indebtedness ceases to be a Restricted  Subsidiary or
     transfers  such  Indebtedness  (other than to the  Company or a  Restricted

of  Indebtedness  by  the  Company  and  its  Restricted   Subsidiaries  of  the
Indebtedness  of  such  Non-Restricted   Subsidiary  as  of  the  time  of  such
redesignation  to the  extent  such  Indebtedness  does not  already  constitute
Indebtedness of the Company or one of its Restricted Subsidiaries.

SECTION 4.09.  RESTRICTED PAYMENTS.

     (a) The  Company  shall not,  and shall not  permit  any of its  Restricted
Subsidiaries to, directly or indirectly:

     referred  to as  "Restricted  Payments"),  unless,  at  the  time  of  such
     Restricted Payment:

          (less the cost of such sale, liquidation or repayment, if any) and

     amount of such trade credit shall not exceed $25 million at any one time;

          (viii) the payment of cash  dividends on the Preferred  Stock accruing

SECTION 4.10.  ASSET SALES.

     (a) The  Company  will  not,  and will  not  permit  any of its  Restricted
Subsidiaries to cause, make or suffer to exist any Asset Sale, unless:


                                       35
<PAGE>


          (i) no Default exists or is continuing  immediately prior to and after
     giving effect to such Asset Sale;

          (ii) the Company (or the  Restricted  Subsidiary,  as the case may be)
     receives consideration at the time of such Asset Sale at least equal to the
     fair  market  value  (evidenced  for  purposes  of this  Section  4.10 by a
     resolution of the Board of Directors set forth in an Officers'  Certificate
     delivered to the Trustee) of the assets sold or otherwise disposed of; and

          (iii) at  least  80% of the  consideration  therefor  received  by the
     Company  or  such  Restricted  Subsidiary  is  in  the  form  of  (w)  Cash
     Equivalents,  (x) Replacement  Assets, (y) publicly traded Equity Interests
     of a Person who is,  directly or  indirectly,  engaged  primarily in one or
     more  Cable  Businesses;  provided,  however,  that  the  Company  or  such
     Restricted  Subsidiary  shall Monetize such Equity Interests by sale to one
     or more Persons  (other than to the Company or a  Subsidiary  thereof) at a
     price not less than the fair market  value  thereof  within 180 days of the
     consummation  of such Asset Sale, or (z) any  combination  of the foregoing
     clauses  (w) through  (y);  provided,  however,  that the amount of (x) any
     liabilities (as shown on the Company's or such Restricted Subsidiary's most
     recent  balance  sheet  or in the  notes  thereto)  of the  Company  or any
     Restricted  Subsidiary  (other  than  liabilities  that are by their  terms
     subordinated  to the Notes) that are assumed by the  transferee of any such
     assets and (y) any notes or other  obligations  received  by the Company or
     any such  Restricted  Subsidiary  from such transferee that are within five
     Business Days converted by the Company or such  Restricted  Subsidiary into
     cash,  shall be deemed to be Cash  Equivalents  (to the  extent of the Cash
     Equivalents received in such conversion) for purposes of this clause (iii).

     (b) Within 360 days after any Asset Sale,  the  Company (or the  Restricted
Subsidiary,  as the case may be) shall  cause the Net  Proceeds  from such Asset
Sale:

          (i) to be used to  permanently  reduce  Indebtedness  of a  Restricted
     Subsidiary; or

          (ii) to be invested or reinvested in Replacement Assets.

     Pending  final  application  of any  such Net  Proceeds,  the  Company  may
temporarily  reduce  revolving  credit  borrowings or otherwise  invest such Net
Proceeds  in any  manner  that  is  not  prohibited  by  this  Indenture  or the
indentures for the Applicable Notes or the Other Qualified Notes.

     Any Net  Proceeds  from any Asset Sale that are not used or  reinvested  as
provided  in the  preceding  sentence  constitute  "Excess  Proceeds."  When the
aggregate amount of Excess Proceeds exceeds $15 million,  the Company shall make
an offer (an "Asset  Sale  Offer") to all  holders of Notes and Other  Qualified
Notes to purchase  the  maximum  principal  amount of Notes and Other  Qualified
Notes  (determined  on a pro  rata  basis  according  to the  accreted  value or
principal amount, as the case may be, of the Notes and the Other Qualified Notes
and in accordance with Section  3.09(g)(i);  provided,  however,  that the Asset
Sale Offer must be made first to the holders of the  Applicable  Notes) that may
be  purchased  out  of  the  Excess  Proceeds,   if  any,  remaining  after  the
consummation  of the  aforementioned  Asset  Sale  Offer to the  holders  of the
Applicable  Notes (x) with respect to the Other  Qualified  Notes,  based on the
terms set forth in the  indenture  related to each issue of the Other  Qualified
Notes and (y)


                                       36
<PAGE>


with respect to the Notes,  at an offer price in cash in an amount equal to 100%
of the outstanding principal amount thereof plus accrued and unpaid interest, if
any,  to the date fixed for the closing of such offer,  in  accordance  with the
procedures  set forth in Section 3.09 hereof.  To the extent that the  aggregate
principal  amount  or  accreted  value,  as the case may be,  of Notes and Other
Qualified Notes tendered pursuant to an Asset Sale Offer is less than the Excess
Proceeds,  if any, remaining after the consummation of the aforementioned  Asset
Sale Offer to the  holders of the  Applicable  Notes,  the  Company may use such
deficiency for general corporate purposes.  If the aggregate principal amount or
accreted  value,  as the  case  may be,  of  Notes  and  Other  Qualified  Notes
surrendered by holders  thereof exceeds the amount of Excess  Proceeds,  if any,
remaining after the consummation of the  aforementioned  Asset Sale Offer to the
holders of the Applicable  Notes,  then such remaining  Excess Proceeds shall be
allocated pro rata according to accreted value or principal  amount, as the case
may be,  to the  Notes  and  each  issue of the  Other  Qualified  Notes  and in
accordance with Section  3.09(g)(ii),  and the Trustee shall select the Notes to
be  purchased  from the amount  allocated to the Notes on the basis set forth in
Section 3.09(e)  hereof.  Upon completion of such offers to purchase each of the
Applicable  Notes and the Notes and the Other  Qualified  Notes,  the  amount of
Excess  Proceeds will be reset at zero. No such Asset Sale Offer to purchase the
Notes and Other  Qualified  Notes  shall be  required  to be made by the Company
pursuant to the foregoing  provisions if there are no Excess Proceeds  remaining
after the consummation of the Asset Sale Offer made to holders of the Applicable
Notes.

     (c) Notwithstanding the provisions of Sections 4.10(a) and (b): the Company
and its Subsidiaries may:

          (i) sell,  lease,  transfer,  convey or otherwise dispose of assets or
     property  acquired after October 14, 1993, by the Company or any Subsidiary
     in a  sale-and-leaseback  transaction  so long as the proceeds of such sale
     are applied within five Business Days to permanently reduce Indebtedness of
     a  Restricted  Subsidiary  or if  there  is no  such  Indebtedness  or such
     proceeds  exceed  the amount of such  Indebtedness  then such  proceeds  or
     excess  proceeds are  reinvested  in a  Replacement  Assets within 360 days
     after such sale, lease, transfer, conveyance or disposition;

          (ii) (x) swap or exchange  assets or property with a Cable  Controlled
     Subsidiary or (y) issue, sell, lease, transfer, convey or otherwise dispose
     of  equity  securities  of any of the  Company's  Subsidiaries  to a  Cable
     Controlled  Subsidiary,  in  each of  cases  (x) and (y) so long as (A) the
     ratio of  Indebtedness  to Annualized Pro Forma EBITDA of the Company after
     such  transaction  is equal to or less  than the ratio of  Indebtedness  to
     Annualized  Pro Forma  EBITDA of the  Company  immediately  preceding  such
     transaction;  provided,  however,  that if the  ratio  of  Indebtedness  to
     Annualized  Pro Forma  EBITDA of the  Company  immediately  preceding  such
     transaction is 6:1 or less,  then the ratio of  Indebtedness  to Annualized
     Pro  Forma  EBITDA  of the  Company  may be 0.5  greater  than  such  ratio
     immediately  preceding  such  transaction  and (B) either (I) the assets so
     contributed consist solely of a license to operate a Cable Business and the
     Net  Households  covered  by all of  the  licenses  to  operate  cable  and
     telephone  systems  held by the  Company  and its  Restricted  Subsidiaries
     immediately  after and giving effect to such transaction  equals or exceeds
     the  number of Net  Households  covered by all of the  licenses  to operate
     cable  and  telephone  systems  held  by the  Company  and  its  Restricted
     Subsidiaries  immediately  prior to such  transaction or (II) the assets so
     contributed  consist  solely of Cable  Assets and the value of the  Capital
     Stock received, immediately after and giving effect to such transaction, as
     determined  by an  investment  banking  firm of  recognized  standing  with
     knowledge  of the


                                       37
<PAGE>


     Cable Business,  equals or exceeds the value of Cable Assets  exchanged for
     such Capital Stock;

          (iii) sell,  transfer or otherwise dispose of Long  Distance/Microwave
     Assets; or

          (iv) issue,  sell,  lease,  transfer,  convey or otherwise  dispose of
     Equity  Interests  (other than  Disqualified  Stock) of the Company (or any
     Capital   Stock  Sale  Proceeds   therefrom)   to  any  Person   (including
     Non-Restricted Subsidiaries).

SECTION 4.11.  TRANSACTIONS WITH AFFILIATES.

     The  Company  shall  not,  and  shall  not  permit  any of  its  Restricted
Subsidiaries  to,  sell,  lease,  transfer  or  otherwise  dispose of any of its
properties  or assets to, or purchase any property or assets from, or enter into
or amend any  contract,  agreement,  understanding,  loan,  advance or guarantee
with, or for the benefit of, any Affiliate (each of the foregoing, an "Affiliate
Transaction"), unless:

     (a) such  Affiliate  Transaction  is on terms that are no less favorable to
the Company or the relevant  Subsidiary than those that could have been obtained
in a comparable  transaction by the Company or such Subsidiary with an unrelated
Person and

     (b) the Company delivers to the Trustee:

          (i) with  respect to any  Affiliate  Transaction  involving  aggregate
     payments  in excess of $1 million or any series of  Affiliate  Transactions
     with an Affiliate  involving  aggregate payments in excess of $1 million, a
     resolution of the Board of Directors set forth in an Officers'  Certificate
     certifying that such Affiliate  Transaction  complies with Section 4.11 (a)
     and  such   Affiliate   Transaction  is  approved  by  a  majority  of  the
     disinterested directors on the Board of Directors; and

          (ii) with respect to any  Affiliate  Transaction  involving  aggregate
     payments in excess of $25 million or any series of  Affiliate  Transactions
     with an Affiliate involving aggregate payments in excess of $25 million, an
     opinion  as to the  fairness  to the  Company  or  such  Subsidiary  from a
     financial  point of view issued by an  investment  banking firm of national
     standing with high yield experience together with an Officers'  Certificate
     to the effect that such opinion  complies with this clause (ii);  provided,
     however, that notwithstanding the foregoing provisions, the following shall
     not be deemed to be Affiliate Transactions:

               (1) any employment  agreement  entered into by the Company or any
          of its  Subsidiaries in the ordinary course of business and consistent
          with the past  practice  of the  Company  or its  predecessor  or such
          Subsidiary;

               (2)  transactions   between  or  among  the  Company  and/or  its
          Restricted Subsidiaries;

               (3)  transactions  permitted  by the  provisions  of Section 4.09

<PAGE>


               (4) Liens  permitted  under Section 4.07 hereof which are granted
          by the Company or any of its  Subsidiaries to an unrelated  Person for
          the benefit of the Company or any other Subsidiary of the Company;

               (5) any  transaction  pursuant to an  agreement  in effect on the
          Issuance Date;

               (6) the  incurrence of  Indebtedness  by a Restricted  Subsidiary
          where such Indebtedness is owed to the holders of the Equity Interests
          of such Restricted Subsidiary on a pro rata basis and on substantially
          identical principal financial terms;

               (7) management,  operating,  service or  interconnect  agreements
          entered  into in the  ordinary  course  of  business  with  any  Cable
          Business  in which the  Company or any  Restricted  Subsidiary  has an
          Investment  and  which is not a Cable  Controlled  Subsidiary  (and of
          which no  Affiliate  of the  Company is an  Affiliate  other than as a
          result of such Investment); and

               (8) any tax sharing agreement.

SECTION 4.12.  DIVIDENDS AND OTHER PAYMENT RESTRICTIONS AFFECTING RESTRICTED
               SUBSIDIARIES.

     The  Company  shall  not,  and  shall  not  permit  any of  its  Restricted
Subsidiaries to, directly or indirectly,  create or otherwise cause or suffer to
exist or become  effective any  encumbrance or restriction on the ability of any
Restricted Subsidiary to:

     (a) (i) pay dividends or make any other distributions to the Company or any
of its  Subsidiaries  (A) on its Capital  Stock or (B) with respect to any other
interest or  participation  in, or  measured  by, its  profits,  or (ii) pay any
indebtedness owed to the Company or any of its Subsidiaries, or

     (b) make loans or advances to the Company or any of its Subsidiaries, or

     (c) transfer any of its  properties  or assets to the Company or any of its
Subsidiaries,  except for such encumbrances or restrictions existing under or by
reason of:

          (i) Existing Indebtedness as in effect on the Issuance Date;

          (ii) this Indenture and the Notes;

          (iii) any agreement covering or relating to Indebtedness  permitted to
     be incurred under Section  4.08(b)(i),  (ii),  (iii),  (iv), (v), (viii) or
     (ix) hereof (but only, in the case of Section 4.08(b)(viii) or (ix), to the
     extent  contemplated by the then-existing  Credit Facility),  provided that
     the  provisions of such agreement  permit any action  referred to in clause
     (a) above in aggregate amounts sufficient to enable the payment of interest
     and  principal  and  mandatory  repurchases  pursuant  to the terms of this
     Indenture and the Notes,  but provided further that: (x) any such agreement
     may nevertheless  encumber,  prohibit or restrict any action referred to in
     clause (a) above if an event of default  under such  agreement has occurred
     and is  continuing  or would occur as a result of any such action;  and (y)
     any such agreement may nevertheless  contain (I) restrictions  limiting the
     payment of dividends or the making of any other  distributions  to all or a


                                       39
<PAGE>


     portion of excess cash-flow (or any similar  formulation  thereof) and (II)
     subordination  provisions governing Indebtedness owed to the Company or any
     Restricted Subsidiary;

          (iv) applicable law;

          (v) any instrument governing Indebtedness or Capital Stock of a Person
     acquired by the Company or any of its Subsidiaries as in effect at the time
     of such acquisition (except to the extent such Indebtedness was incurred in
     connection with such acquisition),  which encumbrance or restriction is not
     applicable to any Person, or the properties or assets of any Person,  other
     than the Person,  or the  property or assets of the  Person,  so  acquired;
     provided  that the  EBITDA  of such  Person is not taken  into  account  in
     determining  whether such  acquisition  was  permitted by the terms of this
     Indenture;  (vi) customary nonassignment  provisions in leases entered into
     in the ordinary course of business and consistent with past practices;

          (vii) provisions of joint venture or stockholder  agreements,  so long
     as such provisions are determined by a resolution of the Board of Directors
     to be, at the time of such determination, customary for such agreements;

          (viii) with respect to clause (c) above,  purchase  money  obligations
     for property  acquired in the ordinary course of business or the provisions
     of any agreement with respect to any Asset Sale (or transaction  which, but
     for its size,  would be an Asset  Sale),  solely with respect to the assets
     being sold; or

          (ix)   permitted   Refinancing   Indebtedness,   provided   that   the
     restrictions   contained  in  the  agreements  governing  such  Refinancing
     Indebtedness are determined by a resolution of the Board of Directors to be
     no more  restrictive  than those contained in the agreements  governing the
     Indebtedness being refinanced.

SECTION 4.13.  CHANGE OF CONTROL.

     (a) Upon the  occurrence  of a Change of  Control  Triggering  Event,  each
Holder of Notes shall have the right to require the Company to repurchase all or
any part (equal to 1,000  pounds  sterling or an integral  multiple  thereof) of
such Holder's Notes pursuant to the offer  described in Section 3.09 hereof (the
"Purchase  Offer") at a purchase  price  equal to 101% of the  principal  amount
thereof  plus  accrued  and  unpaid  interest  thereon,  if any,  to the date of
purchase (the "Change of Control Payment").

     (b) Within 40 days following any Change of Control  Triggering  Event,  the
Company shall mail to each Holder the notice provided by Section 3.09(e).

SECTION 4.14.  PAYMENT OF ADDITIONAL AMOUNTS.

     At least 10 days prior to the first date on which  payment of principal and
any premium or  interest on the Notes is to be made,  and at least 10 days prior
to any  subsequent  such date if there has been any change  with  respect to the
matters set forth in the Officers'  Certificate  described in this Section 4.14,
the Company shall  furnish the Trustee and the Paying  Agent,  if other than the
Trustee,  with an Officers'  Certificate  instructing the Trustee and the Paying
Agent whether the Company is obligated to pay Additional  Amounts (as defined in
Section 3 of the Initial Notes or Section 2 of the Exchange  Notes) with respect
to such payment of principal, or of any premium or interest on the Notes. If the
Company


                                       40
<PAGE>


will be obligated to pay Additional  Amounts with respect to such payment,  then
such Officers' Certificate shall specify by country the amount, if any, required
to be withheld on such  payments to such Holders and the Company will pay to the
Trustee or the Paying Agent such Additional Amounts. The Company shall indemnify
the Trustee and the Paying Agent for, and hold them harmless against,  any loss,
liability or expense  reasonably  incurred  without  negligence  or bad faith on
their part arising out of or in connection  with actions taken or omitted by any
of them in reliance on any Officers'  Certificate  furnished to them pursuant to
this Section 4.14.

     Whenever in this Indenture there is mentioned,  in any context, the payment
of principal (and premium,  if any), Offer Amount,  interest or any other amount
payable  under or with  respect  to any Note  such  mention  shall be  deemed to
include  mention  of the  payment of  Additional  Amounts  provided  for in this
Section  4.14 and Section 3 of the Initial  Notes (or Section 2 of the  Exchange
Notes) to the extent that,  in such  context,  Additional  Amounts are,  were or
would be payable in respect  thereof  pursuant to the provisions of this Section
4.14 and Section 3 of the Initial Notes (or Section 2 of the Exchange Notes) and
express  mention of the payment of  Additional  Amounts (if  applicable)  in any
provisions  hereof shall not be construed  as  excluding  Additional  Amounts in
those provisions hereof where such express mention is not made (if applicable).

Company is the surviving corporation),  or sell, assign, transfer, lease, convey
or otherwise  dispose of all or substantially all of its properties or assets in
one or more  related  transactions  to,  another  corporation,  Person or entity
unless:

     (a) the Company is the  surviving  corporation  or the entity or the Person
formed by or  surviving  any such  consolidation  or merger  (if other  than the

     (c)  immediately  after  such  transaction  no  Default or Event of Default
exists;

     (d) the  Company or any entity or Person  formed by or  surviving  any such
consolidation or merger,  or to which such sale,  assignment,  transfer,  lease,

Indebtedness  to Annualized  Pro Forma EBITDA equal to or less than the ratio of

<PAGE>


Company immediately preceding such transaction is 6:1 or less, then the ratio of
Indebtedness  to  Annualized  Pro Forma EBITDA of the Company may be 0.5 greater
than such ratio immediately preceding such transaction; and

     (e)  such  transaction  would  not  result  in the  loss  of  any  material
authorization or Material License of the Company or its Subsidiaries.

SECTION 5.02.  SUCCESSOR CORPORATION SUBSTITUTED.

     Upon any consolidation or merger, or any sale, assignment, transfer, lease,

such sale, assignment,  transfer, lease, conveyance or other disposition is made
shall succeed to, and be substituted  for and may exercise every right and power
of, the Company under this  Indenture  with the same effect as if such successor
Person  has been  named  as the  Company  herein;  provided,  however,  that the
predecessor  Company  in  the  case  of a  sale,  assignment,  transfer,  lease,
conveyance or other disposition shall not be released from the obligation to pay
the principal of and interest on the Notes.

SECTION 6.02.  ACCELERATION.

     If an Event of Default (other than an Event of Default specified in clauses
(g) and (h) of Section 6.01  hereof)  occurs and is  continuing,  the Trustee by
notice to the Company, or the Holders of at least 25% in principal amount of the
then outstanding Notes by notice to the Company and the Trustee, may declare all
the  Notes to be due and  payable.  Upon such  declaration,  the  principal  of,
premium,  if  any,  and  interest  on,  the  Notes  shall  be  due  and  payable
immediately.  If an Event of Default  specified  in clause (g) or (h) of Section
6.01 hereof  occurs,  such an amount shall ipso facto become and be  immediately
due and payable  without any declaration or other act on the part of the Trustee
or any  Holder.  The  Holders  of a  majority  in  principal  amount of the then
outstanding  Notes by notice to the Trustee may rescind an acceleration  and its
consequences  if the  rescission  would not conflict with any judgment or decree
and if all  existing  Events  of  Default  have  been  cured  or  waived  except
nonpayment  of principal or interest  that has become due solely  because of the
acceleration.  In the case of any Event of Default pursuant to the provisions of
Section 6.01 occurring by reason of any willful  action (or inaction)  taken (or
not taken) by or on behalf of the Company with the intention of avoiding payment
of the premium  that the Company  would have had to pay if the Company  then had
elected to redeem the Notes  pursuant to Section 7 of the Initial Notes (Section
6 in the case of the Exchange Notes),  an equivalent  premium shall, upon demand
of the Holders of at least 25% in principal amount of the then outstanding Notes
delivered to the Company and the Trustee, also become and be immediately due and
payable to the extent  permitted  by law,  anything in this  Indenture or in the
Notes contained to the contrary  notwithstanding.  If an Event of Default occurs
prior to April 1, 2003, by reason of any willful action (or inaction)  taken (or
not taken) by or on behalf of the Company  with the  intention  of avoiding  the
prohibition  on  redemption  of the Notes  prior to April 1, 2003,  pursuant  to
Section 7 of the Initial  Notes  (Section 6 in the case of the Exchange  Notes),
then the premium  payable for purposes of this  paragraph  for each of the years
beginning on April 1 of the years (March 13 in the case of 1998) set forth below
shall,  subject to the foregoing  demand, be as set forth in the following table
expressed as a percentage of the amount that would  otherwise be due pursuant to
this Section 6.02 hereof but for the provisions of this sentence.

             Year                             Percentage
             1998............................ 109.500%
             1999............................ 108.550%
             2000............................ 107.600%
             2001............................ 106.650%
             2002............................ 105.700%


SECTION 6.03.  OTHER REMEDIES.

     If an Event of Default occurs and is continuing, the Trustee may pursue any
available remedy to collect the payment of principal or interest on the Notes or
to enforce the performance of any provision of the Notes or this Indenture.

     The Trustee may  maintain a  proceeding  even if it does not possess any of
the Notes or does not produce any of them in the proceeding. A delay or omission
by the Trustee or any Holder in exercising any right or remedy  accruing upon an
Event of Default  shall not impair the right or remedy or constitute a waiver of
or  acquiescence  in the Event of Default.  All remedies are  cumulative  to the
extent permitted by law.


                                       44
<PAGE>


SECTION 6.04.  WAIVER OF PAST DEFAULTS.

     The Holders of a majority in principal amount of the then outstanding Notes
by notice to the Trustee  may waive an existing  Default or Event of Default and
its consequences  except a continuing Default or Event of Default in the payment
of the principal of or interest on any Note.  When a Default or Event of Default
is  waived,  it is cured and  ceases;  but no such  waiver  shall  extend to any
subsequent or other Default or impair any right consequent thereon.

SECTION 6.05.  CONTROL BY MAJORITY.

     The Holders of a majority in principal amount of the then outstanding Notes
may  direct the time,  method and place of  conducting  any  proceeding  for any
remedy  available to the Trustee or exercising  any trust or power  conferred on
it. However,  the Trustee may refuse to follow any direction that conflicts with
law or this Indenture,  is unduly prejudicial to the rights of other Holders, or
would involve the Trustee in personal liability.

SECTION 6.06.  LIMITATION ON SUITS.

     A Holder may pursue a remedy with  respect to this  Indenture  or the Notes
only if:

     (a) the  Holder  gives  to the  Trustee  notice  of a  continuing  Event of
Default;

     (b) the Holders of at least 25% in principal amount of the then outstanding
Notes make a request to the Trustee to pursue the remedy;

     (c) such Holder or Holders offer to the Trustee  indemnity  satisfactory to
the Trustee against any loss, liability or expense;

     (d) the  Trustee  does not  comply  with the  request  within 60 days after
receipt of the request and the offer of indemnity; and

     (e) during such 60-day period the Holders of a majority in principal amount
of the then outstanding  Notes do not give the Trustee a direction  inconsistent
with the request.

     A Holder  may not use this  Indenture  to  prejudice  the rights of another
Holder or to obtain a preference or priority over another Holder.

SECTION 6.07.  RIGHTS OF HOLDERS TO RECEIVE PAYMENT.

     Notwithstanding  any other  provision of this  Indenture,  the right of any
Holder of a Note to receive payment of principal and interest on the Note, on or
after the respective  due dates  expressed in the Note, or to bring suit for the
enforcement of any such payment on or after such respective dates,  shall not be
impaired  or affected  without  the consent of the Holder made  pursuant to this
Section.

SECTION 6.08.  COLLECTION SUIT BY TRUSTEE.

     If an Event of Default  specified  in Section  6.01(a) or (b) occurs and is
continuing,  the Trustee may recover  judgment in its own name and as trustee of
an express  trust  against  the Company for the whole  amount of  principal  and
interest  remaining  unpaid on the Notes and interest on overdue  principal  and
interest and such further  amount as shall be sufficient to cover the costs and,
to  the  extent  lawful,


                                       45
<PAGE>


expenses  of  collection,  including  the  reasonable  compensation,   expenses,
disbursements and advances of the Trustee, its agents and counsel.

SECTION 6.09.  TRUSTEE MAY FILE PROOFS OF CLAIM.

     The Trustee may file such proofs of claim and other  papers or documents as
may be necessary or advisable in order to have the claims of the Trustee and the
Holders  allowed  in any  judicial  proceedings  relative  to the  Company,  its
creditors or its property. Nothing contained herein shall be deemed to authorize
the  Trustee  to  authorize  or  consent  to or accept or adopt on behalf of any
Holder  any  plan of  reorganization,  arrangement,  adjustment  or  composition
affecting  the Notes or the rights of any Holder  thereof,  or to authorize  the
Trustee to vote in respect of the claim of any Holder in any such proceeding.

SECTION 6.10.  PRIORITIES.

     If the Trustee  collects any money  pursuant to this Article,  it shall pay
out the money in the following order:

     First: to the Trustee for amounts due under Section 7.07 hereof;

     Second:  to Holders for  amounts due and unpaid on the Notes for  principal
and  interest  (and  Additional  Amounts,  if  applicable),   ratably,   without
preference or priority of any kind,  according to the amounts due and payable on
the Notes for principal and interest, respectively; and

     Third: to the Company.

     The  Trustee  may fix a record  date and  payment  date for any  payment to
Holders made pursuant to this Section.

SECTION 6.11.  UNDERTAKING FOR COSTS.

     In any suit for the enforcement of any right or remedy under this Indenture
or in any suit  against the  Trustee for any action  taken or omitted by it as a
Trustee,  a court in its discretion may require the filing by any party litigant
in the suit of an undertaking to pay the costs of the suit, and the court in its
discretion may assess reasonable costs,  including  reasonable  attorneys' fees,
against any party litigant in the suit, having due regard to the merits and good
faith of the claims or defenses  made by the party  litigant.  This Section does
not apply to a suit by the Trustee,  a suit by a Holder pursuant to Section 6.07
hereof,  or a suit by Holders of more than 10% in  principal  amount of the then
outstanding Notes.

                                    TRUSTEE



SECTION 7.01.  DUTIES OF TRUSTEE.

     (a) If an Event of Default  has  occurred  and is  continuing,  the Trustee
shall exercise such of the rights and powers vested in it by this Indenture, and
use the same degree of care and skill in their exercise,  as a prudent man would
exercise or use under the circumstances in the conduct of his own affairs.

     (b) Except during the  continuance of an Event of Default:  (i) the Trustee
need perform only those duties that are specifically set forth in this Indenture

conclusively  rely, as to the truth of the statements and the correctness of the
opinions  expressed  therein,  upon  certificates  or opinions  furnished to the
Trustee and  conforming to the  requirements  of this  Indenture.  However,  the
Trustee shall examine the certificates and opinions to determine  whether or not
they  conform  to  the  requirements  of  this  Indenture  and  to  confirm  the
correctness of all mathematical computations.

     (c) The Trustee may not be relieved  from  liability  for its own negligent
action, its own negligent failure to act, or its own willful misconduct,  except
that:  (i) this  paragraph  does not limit the effect of  paragraph  (b) of this
Section  7.01;  (ii) the  Trustee  shall not be liable for any error of judgment
made in good faith by a Trust Officer,  unless it is proved that the Trustee was

liable  with  respect  to any  action it takes or omits to take in good faith in
accordance with a direction received by it pursuant to Section 6.05 hereof.

Trustee is subject to paragraphs (a), (b) and (c) of this Section 7.01.

it except as the Trustee may agree in writing  with the  Company.  Money held in

SECTION 7.03.  INDIVIDUAL RIGHTS OF TRUSTEE.

     The Trustee in its individual or any other capacity may become the owner or
pledgee of Notes and may  otherwise  deal with the Company or an Affiliate  with
the same rights it would have if it were not Trustee.  Any Agent may do the same

hereof.

     The Trustee makes no  representation as to the validity or adequacy of this
Indenture or the Notes, it shall not be accountable for the Company's use of the

the  Company  in the  Indenture  or any  statement  in the Notes  other than its
authentication  or for  compliance by the Company with the  Registration  Rights
Agreement.

SECTION 7.05.  NOTICE OF DEFAULTS.

     If a Default or Event of  Default  occurs  and is  continuing  and if it is
known to the Trustee,  the Trustee shall mail to Holders a notice of the Default
or Event of  Default  within 90 days  after it  occurs.  Except in the case of a

     Trustee  shall mail to Holders a brief  report  dated as of such  reporting
date that complies with TIA  (Section)  313(a) if and to the extent  required by

limited by any law on compensation of a trustee of


                                       48
<PAGE>


an express trust.  The Company shall  reimburse the Trustee upon request for all
reasonable  disbursements,  expenses and  advances  incurred or made by it. Such

liability incurred by the Trustee through negligence or bad faith.

     To secure the Company's  payment  obligations in this Section,  the Trustee
shall have a lien prior to the Notes on all money or property  held or collected
by the Trustee,  except  money or property  held in trust to pay  principal  and
interest on particular Notes.

     Without  prejudice  to any other  rights  available  to the  Trustee  under
applicable  law, when the Trustee incurs  expenses or renders  services after an
Event of Default  specified in Section  6.01(g) or (h) occurs,  the expenses and
the  compensation  for the  services  are  intended  to  constitute  expenses of
administration under any Bankruptcy Law.

     All amounts owing to the Trustee under this Section shall be payable by the
Company in United States dollars.

SECTION 7.08.  REPLACEMENT OF TRUSTEE.

     A  resignation  or removal of the  Trustee and  appointment  of a successor
Trustee shall become effective only upon the successor  Trustee's  acceptance of
appointment as provided in this Section.

     The  Trustee  may resign by so  notifying  the  Company.  The  Holders of a
majority  in  principal  amount of the then  outstanding  Notes may  remove  the
Trustee by so notifying the Trustee and the Company.  The Company may remove the
Trustee if:

     (a) the  Trustee  fails to comply  with  Section  7.10  hereof,  unless the
Trustee's duty to resign is stayed as provided in TIA (Section) 310(b);

     (b) the  Trustee is  adjudged a bankrupt  or an  insolvent  or an order for
relief is entered with respect to the Trustee under any Bankruptcy Law;

     (c) a  Custodian  or public  officer  takes  charge of the  Trustee  or its
property; or

     (d) the Trustee becomes incapable of acting.

     If the Trustee  resigns or is removed or if a vacancy  exists in the office
of Trustee  for any  reason,  the  Company  shall  promptly  appoint a successor
Trustee.  Within one year after the successor Trustee takes office,  the Holders
of a majority in principal  amount of the then  outstanding  Notes may appoint a
successor Trustee to replace the successor Trustee appointed by the Company.


                                       49
<PAGE>


     If a  successor  Trustee  does not take  office  within  60 days  after the
retiring Trustee resigns or is removed, the retiring Trustee, the Company or the
Holders of at least 10% in principal  amount of the then  outstanding  Notes may
petition any court of competent  jurisdiction for the appointment of a successor
Trustee.

     If the  Trustee  fails to comply  with  Section  7.10  hereof,  unless  the
Trustee's  duty to resign is stayed as provided  in TIA  (Section)  310(b),  any
Holder  who has been a bona fide  Holder of a Note for at least six  months  may
petition any court of competent  jurisdiction for the removal of the Trustee and
the appointment of a successor Trustee.

to the retiring Trustee and to the Company. Thereupon the resignation or removal
of the retiring Trustee shall become effective,  and the successor Trustee shall
have all the rights, powers and duties of the Trustee under this Indenture.  The
successor Trustee shall mail a notice of its succession to Holders. The retiring
Trustee  shall  promptly  transfer  all  property  held by it as  Trustee to the
successor  Trustee,  subject to the lien  provided  for in Section  7.07 hereof.
Notwithstanding replacement of the Trustee pursuant to this Section 7.08 hereof,
the  Company's  obligations  under  Section 7.07 hereof  shall  continue for the
benefit of the  retiring  trustee  with  respect  to  expenses  and  liabilities
incurred by it prior to such replacement.

SECTION 7.09.  SUCCESSOR TRUSTEE BY MERGER, ETC.

     If the Trustee  consolidates,  merges or converts into, or transfers all or
substantially all of its corporate trust business to, another  corporation,  the
successor corporation without any further act shall be the successor Trustee.

SECTION 7.10.  ELIGIBILITY; DISQUALIFICATION.

     This Indenture  shall always have a Trustee who satisfies the  requirements
of TIA  (Section)  310(a)(1)  and (5). The Trustee  shall always have a combined

TIA  (Section)  310(b).   The  following   indentures  shall  be  deemed  to  be

                             DISCHARGE OF INDENTURE

SECTION 8.01.  TERMINATION OF COMPANY'S OBLIGATIONS.

     This  Indenture  shall  cease  to be of  further  effect  (except  that the
Company's  obligations  under  Sections 7.07 and 8.03 hereof shall survive) when
all outstanding Notes  theretofore  authenticated and issued have been delivered
to the  Trustee  for  cancellation  and the  Company  has paid all sums  payable
hereunder.

SECTION 8.02.  OPTION TO EFFECT DEFEASANCE.

     The Company  may, at the option of its Board of  Directors  evidenced  by a
resolution  set forth in an Officers'  Certificate,  at any time,  elect to have
this Section 8.02 be applied to all  outstanding  Notes upon compliance with the
conditions set forth below in this Section.  Upon the Company's election to have
this Section 8.02 apply to all the outstanding Notes, the Company shall, subject
to the satisfaction of the conditions set forth in the next paragraph, be deemed
to have been  discharged  from its  obligations  with respect to all outstanding
Notes on the date such conditions are satisfied (hereinafter, "Defeasance"). For
this purpose, Defeasance means that the Company shall be deemed to have paid and

and this  Indenture  (and the  Trustee,  on demand of and at the  expense of the
Company,  shall execute proper instruments  acknowledging the same),  except for
the  following  provisions  which shall survive  until  otherwise  terminated or
discharged hereunder:  (i) the rights of Holders of outstanding Notes to receive

     sterling  sufficient or U.K.  Government  Obligations  the principal of and
     interest on which will be sufficient or a combination thereof sufficient in
     the  opinion  of  a  nationally   recognized  firm  of  independent  public
     accountants,   expressed  in  a  written  certification  thereof  (in  form
     satisfactory to the Trustee) to pay the principal of, premium,  if any, and
     interest on the outstanding Notes on the stated date for payment thereof or
     on the applicable redemption date, as the case may be, of such principal or
     installment  of  principal  of,  premium,  if  any,  and  interest  on  the
     outstanding Notes;

          (b) the Company  shall have  delivered to the  Trustee,  an Opinion of

     acceptable  to the Trustee  confirming  that:  (A) the Company has received
     from, or there has been published by, the Internal Revenue Service a ruling
     or (B) since the Issuance  Date,  there has been a change in the applicable
     federal  income  tax law,  in either  case to the  effect  that,  and based
     thereon  such Opinion of Counsel  shall  confirm  that,  the Holders of the
     outstanding  Notes  will not  recognize  income,  gain or loss for


                                       51
<PAGE>


     federal  income tax  purposes  as a result of such  Defeasance  and will be
     subject to federal  income tax on the same amounts,  in the same manner and
     at the same  times as would have been the case if such  Defeasance  had not
     occurred;

          (c) no Event of Default  shall have  occurred and be continuing on the
     date of such Defeasance  (other than an Event of Default  resulting from or
     related to the incurrence of Indebtedness,  the proceeds of which are to be
     applied to such deposit) or, insofar as Sections 6.01(g) and (h) hereof are
     concerned,  at any time in the period ending on the 91st day after the date
     of deposit  (or greater  period of time in which any such  deposit of trust
     funds may remain  subject to the effect of any  Bankruptcy  Law  insofar as
     those apply to the deposit by the Company);

          (d) such  Defeasance  shall not result in a breach or violation of, or
     constitute a default  under,  any material  agreement or instrument  (other
     than this  Indenture) to which the Company or any of its  Subsidiaries is a
     party or by which the Company or any of its Subsidiaries is bound;

          (e) the  Company  shall have  delivered  to the  Trustee an Opinion of
     Counsel to the effect  that after the 91st day  following  the  deposit (or
     such greater period referred to in (c) above),  the trust funds will not be
     subject to the effect of any applicable Bankruptcy Law;

          (f) the  Company  shall have  delivered  to the  Trustee an  Officers'
     Certificate  stating  that the deposit was not made by the Company with the
     intent of preferring  the Holders of Notes over any other  creditors of the
     Company with the intent of  defeating,  hindering,  delaying or  defrauding
     creditors of the Company or others;

          (g) the deposit  shall not result in the  Company,  the Trustee or the
     trust fund  established  pursuant to (a) above being  subject to regulation
     under the Investment Company Act of 1940, as amended;

          (h) Holders of the Notes will have a valid,  perfected and unavoidable
     (under applicable  Bankruptcy Law), subject to the passage of time referred
     to clause (e) above,  first priority  security interest in the trust funds;
     and

          (i) the  Company  shall have  delivered  to the  Trustee an  Officers'
     Certificate  and an Opinion of Counsel  (subject to customary  exceptions),
     each stating that all conditions  precedent provided for or relating to the
     Defeasance have been complied with.

     "U.K.  Government  Obligations"  means (i) direct obligations of the United
Kingdom that are issued by the Lords  Commissioners of Her Majesty's Treasury or
(ii) obligations of a Person controlled or supervised by and acting as an agency
or instrumentality of the United Kingdom the payment of which is unconditionally
guaranteed  by the  Lords  Commissioners  of Her  Majesty's  Treasury,  and also
includes a  depository  receipt  issued by a bank or trust  company as custodian
with respect to any such U.K.  Government  Obligation  or a specific  payment of
interest on or principal  of any such U.K.  Government  Obligation  held by such
custodian for the account of the holder of a depository  receipt;  provided that
(except  as  required  by law)  such  custodian  is not  authorized  to make any
deduction from the amount payable to the holder of such depository  receipt from
any  amount  received  by  the  custodian  in  respect  of the  U.K.  Government
Obligation  or the  specific  payment of  interest on or  principal  of the U.K.
Government  Obligation  evidenced by such depository  receipt.  In order to have
money  available  on a payment  date to pay  principal  or  interest  (including
Additional Amounts, if applicable) on the Notes, the


                                       52
<PAGE>


U.K.  Government  Obligations shall be payable as to principal or interest on or
before such payment date in such  amounts as will provide the  necessary  money.
U.K. Government Obligations shall not be callable at the issuer's option.

SECTION 8.03.  APPLICATION OF TRUST MONEY.

     The  Trustee  shall  hold in  trust  money or U.K.  Government  Obligations
deposited with it pursuant to Section 8.02 hereof.  It shall apply the deposited
money and the money from U.K.  Government  Obligations  through the Paying Agent
and in accordance  with this  Indenture to the payment of principal and interest
on the Notes.

SECTION 8.04.  REPAYMENT TO COMPANY.

     The Trustee and the Paying  Agent shall  promptly  pay to the Company  upon
request any excess money or securities held by them at any time.

     The Trustee and the Paying  Agent shall pay to the Company upon request any
money  held by them for the  payment  of  principal  or  interest  that  remains
unclaimed for two years after the date upon which such payment shall have become
due; provided,  however, that the Company shall have first caused notice of such
payment to the Company to be mailed to each Holder entitled thereto no less than
30 days prior to such payment. After payment to the Company, the Trustee and the
Paying  Agent  shall have no further  liability  with  respect to such money and
Holders  entitled  to the money must look to the  Company for payment as general
creditors  unless any  applicable  abandoned  property  law  designates  another
Person.

SECTION 8.05.  REINSTATEMENT.

     If (i) the  Trustee  or  Paying  Agent  is  unable  to apply  any  money in
accordance  with  Section  8.03 hereof by reason of any order or judgment of any
court or governmental authority enjoining,  restraining or otherwise prohibiting
such application and (ii) the Holders of at least a majority in principal amount
of the then outstanding  Notes so request by written notice to the Trustee,  the
Company's  obligations  under this  Indenture and the Notes shall be revived and
reinstated  as though no deposit had  occurred  pursuant to Section  8.02 hereof
until such time as the Trustee or Paying  Agent is  permitted  to apply all such
money in accordance  with Section 8.03 hereof or such request is revoked by such
Holders; provided, however, that if the Company makes any payment of interest on
or principal of any Note following the  reinstatement  of its  obligations,  the
Company  shall be  subrogated  to the  rights of the  Holders  of such  Notes to
receive such payment from the money held by the Trustee or Paying Agent.


                                   ARTICLE IX.
                       AMENDMENTS, SUPPLEMENTS AND WAIVERS

SECTION 9.01.  WITHOUT CONSENT OF HOLDERS.

     The Company and the Trustee may amend or supplement  this  Indenture or the
Notes without the consent of any Holder:

     (a) to cure any ambiguity, defect or inconsistency;


                                       53
<PAGE>


     (b) to comply with Section 5.01 hereof;

     (c) to  provide  for  uncertificated  Notes in  addition  to or in place of
certificated Notes;

     (d) to make  any  change  that  does not  adversely  affect  the  interests
hereunder of any Holder; or

     (e)  to  qualify  the  Indenture  under  the  TIA  or to  comply  with  the
requirements of the SEC in order to maintain the  qualification of the Indenture
under the TIA.

SECTION 9.02.  WITH CONSENT OF HOLDERS.

     Subject to Section  6.07  hereof,  the Company and the Trustee may amend or
supplement  this Indenture or the Notes with the written  consent of the Holders
of at least a  majority  in  principal  amount  of the then  outstanding  Notes.
Subject to Sections 6.04 and 6.07 hereof, the Holders of a majority in principal
amount of the Notes then  outstanding may also waive  compliance in a particular
instance by the  Company  with any  provision  of this  Indenture  or the Notes.
However,  without the consent of each Holder affected, an amendment,  supplement
or waiver under this Section may not:

     (a) reduce the amount of Notes whose  Holders must consent to an amendment,
supplement or waiver;

     (b) reduce the  principal  of or change the fixed  maturity  of any Note or
alter the  provisions of Sections 7 and 8 of the Initial Note and Sections 6 and
7 of the  Exchange  Note  (other  than  provisions  relating  to  the  covenants
described under Sections 4.10 and 4.13);

     (c) reduce the rate of or change the time for  payment of  interest  on any
Note;

     (d) waive a default in the payment of the principal of, or interest on, any
Note  (except a  rescission  of  acceleration  of the Notes by the Holders of at
least a majority in aggregate  principal amount of the Notes and a waiver of the
payment default that resulted from such acceleration);

     (e) except as  contemplated by Section  10.07(e),  make any Note payable in
money other than that stated in the Note;

     (f) make any change in Section 6.04 or 6.07 hereof;

     (g) waive a redemption payment with respect to any Note; or

     (h) make any change in the  foregoing  amendment  and waiver  provisions of
this Article 9.

     To secure a consent of the Holders under this Section 9.02, it shall not be
necessary  for the  Holders  to  approve  the  particular  form of any  proposed
amendment,  supplement  or waiver,  but it shall be  sufficient  if such consent
approves the substance thereof.

     After an  amendment,  supplement  or  waiver  under  this  Section  becomes
effective,  the Company shall mail to Holders a notice  briefly  describing  the
amendment or waiver.


                                       54
<PAGE>


SECTION 9.03.  COMPLIANCE WITH TRUST INDENTURE ACT.

     Every  amendment  to this  Indenture  or the Notes  shall be set forth in a
supplemental indenture that complies with the TIA as then in effect.

SECTION 9.04.  REVOCATION AND EFFECT OF CONSENTS.

     Until an amendment, supplement or waiver becomes effective, a consent to it
by a Holder of a Note is a continuing consent by the Holder and every subsequent
Holder  of a Note or  portion  of a Note  that  evidences  the same  debt as the
consenting  Holder's  Note,  even if  notation of the consent is not made on any
Note. However, any such Holder or subsequent Holder may revoke the consent as to
his Note or portion of a Note if the Trustee  receives the notice of  revocation
before  the  date  on  which  the  Trustee  receives  an  Officers'  Certificate
certifying  that the  Holders of the  requisite  principal  amount of Notes have
consented to the amendment, supplement or waiver.

     The Company may,  but shall not be obligated  to, fix a record date for the
purpose of  determining  the  Holders  entitled  to  consent  to any  amendment,
supplement  or  waiver.  If a record  date is fixed,  then  notwithstanding  the
provisions  of the  immediately  preceding  paragraph,  those  Persons  who were
Holders at such record date (or their duly designated  proxies),  and only those
Persons, shall be entitled to consent to such amendment, supplement or waiver or
to revoke any consent previously given,  whether or not such Persons continue to
be Holders  after such record date.  No consent  shall be valid or effective for
more than 90 days after such  record date unless  consents  from  Holders of the
principal amount of Notes required  hereunder for such amendment or waiver to be
effective shall have also been given and not revoked within such 90-day period.

     After an amendment,  supplement or waiver  becomes  effective it shall bind
every Holder,  unless it is of the type  described in any of clauses (a) through
(h) of Section 9.02  hereof.  In such case,  the  amendment or waiver shall bind
each Holder who has consented to it and every  subsequent  Holder that evidences
the same debt as the consenting Holder's Note.

SECTION 9.05.  NOTATION ON OR EXCHANGE OF NOTES.

     The Trustee may place an appropriate  notation about an amendment or waiver
on any Note thereafter authenticated.  The Company in exchange for all Notes may
issue and the Trustee shall authenticate new Notes that reflect the amendment or
waiver.

     Failure to make such notation on a Note or to issue a new Note as aforesaid
shall not affect the validity and effect of such amendment or waiver.

SECTION 9.06.  TRUSTEE PROTECTED.

     The Trustee shall sign all supplemental indentures, except that the Trustee
may, but need not, sign any  supplemental  indenture that adversely  affects its
rights.

                                  MISCELLANEOUS

SECTION 10.01.  TRUST INDENTURE ACT CONTROLS.

     This Indenture is subject to the provisions of the TIA that are required to
be incorporated  into this Indenture (or, prior to the registration of the Notes
pursuant  to  the  Registration  Rights  Agreement,  would  be  required  to  be
incorporated into this Indenture if it were qualified under the TIA), and shall,
to the extent  applicable,  be governed by such provisions.  If any provision of
this Indenture limits,  qualifies,  or conflicts with another provision which is
required (or would be so required) to be  incorporated  in this Indenture by the
TIA, the incorporated provision shall control.

SECTION 10.02.  NOTICES.

     Any notice or  communication  by the Company or the Trustee to the other is
duly given if in writing and  delivered  in Person or mailed by first class mail
to the  other's  address  stated in Section  10.11  hereof.  The  Company or the
Trustee by notice to the other may designate  additional or different  addresses
for subsequent notices or communications.

     Any notice or communication to a Holder shall be mailed by first class mail
to his address  shown on the register kept by the  Registrar.  Failure to mail a
notice or  communication  to a Holder or any  defect in it shall not  affect its
sufficiency with respect to other Holders.

     If a notice or  communication is mailed in the manner provided above within
the time prescribed, it is duly given, whether or not the addressee receives it.

     If the Company mails a notice or communication to Holders,  it shall mail a
copy to the Trustee and each Agent at the same time.

     All other notices or communications shall be in writing.

     In case by reason of the  suspension of regular mail service,  or by reason
of any other cause, it shall be impossible to mail any notice as required by the
Indenture,  then such method of  notification as shall be made with the approval
of the Trustee shall constitute a sufficient mailing of such notice.

SECTION 10.03.  COMMUNICATION BY HOLDERS WITH OTHER HOLDERS.

     Holders may communicate pursuant to TIA (Section) 312(b) with other Holders
with respect to their rights under this Indenture or the Notes. The Company, the
Trustee,  the  Registrar  and  anyone  else  shall  have the  protection  of TIA
(Section) 312(c).

SECTION 10.04.  CERTIFICATE AND OPINION AS TO CONDITIONS PRECEDENT.

     Upon any request or  application  by the Company to the Trustee to take any
action under this Indenture, the Company shall furnish to the Trustee:

     (a) an Officers'  Certificate  stating that, in the opinion of the signers,
all conditions precedent, if any, provided for in this Indenture relating to the
proposed action have been complied with; and


                                       56
<PAGE>


     (b) an Opinion of Counsel stating that, in the opinion of such counsel, all
such conditions precedent have been complied with.

SECTION 10.05.  STATEMENTS REQUIRED IN CERTIFICATE OR OPINION.

     Each  certificate or opinion with respect to compliance with a condition or
covenant  provided for in this  Indenture  (other than pursuant to Section 4.03)
shall include:

     (a) a statement that the Person signing such  certificate or rendering such
opinion has read such covenant or condition;

     (b) a brief  statement  as to the  nature and scope of the  examination  or
investigation   upon  which  the  statements  or  opinions   contained  in  such
certificate or opinion are based;

     (c) a statement  that, in the opinion of such Person,  such Person has made
such  examination  or  investigation  as is  necessary  to enable such Person to
express an informed  opinion as to whether or not such covenant or condition has
been complied with; and

     (d) a statement as to whether or not, in the opinion of such  Person,  such
condition or covenant has been complied with.

SECTION 10.06.  RULES BY TRUSTEE AND AGENTS.

     The  Trustee  may make  reasonable  rules for action  by, or a meeting  of,
Holders.  The  Registrar  or  Paying  Agent  may make  reasonable  rules and set
reasonable requirements for its functions.

SECTION 10.07.  CONVERSION OF CURRENCY.

     The Company covenants and agrees that the following  provisions shall apply
to conversion of currency in the case of the Notes and this Indenture:

     (a) (i) If for the  purposes of obtaining  judgment  in, or  enforcing  the
judgment of, any court in any country,  it becomes necessary to convert into any
other  currency  (the  "Judgment  Currency")  an amount  due in  British  pounds
sterling,  then the conversion shall be made at the Rate of Exchange  prevailing
on the  Business  Day before the day on which the judgment is given or the order
of  enforcement  is made,  as the case may be  (unless a court  shall  otherwise
determine).

          (ii) If there is a change in the Rate of Exchange  prevailing  between
     the  Business Day before the day on which the judgment is given or an order
     of  enforcement  is made, as the case may be (or such other date as a court
     shall  determine),  and the date of receipt of the amount due,  the Company
     shall pay such additional (or, as the case may be, such lesser) amount,  if
     any, as may be necessary  so that the amount paid in the Judgment  Currency
     when  converted at the Rate of Exchange  prevailing  on the date of receipt
     will produce the amount in British pounds sterling originally due.

     (b) In the event of the  winding-up  of the  Company  at any time while any
amount or damages owing under the Notes and this  Indenture,  or any judgment or
order  rendered in respect  thereof,  remains  outstanding,  the  Company  shall
indemnify  and hold the  Holders of Notes and the Trustee  harmless  against any
deficiency  arising or resulting from any variation in rates of exchange between
(1) the date as of which the equivalent of the amount in British pounds sterling
due or  contingently  due under the Notes and this  Indenture  (other than under
this paragraph  (b)) is calculated  for the purposes of


                                       57
<PAGE>


such  winding-up and (2) the final date for the filing of proofs of claim in the
winding-up  of the  Company,  which  is the  date  fixed  by the  liquidator  or
otherwise in accordance with the relevant  provisions of applicable law as being
the  latest  practicable  date as at which  liabilities  of the  Company  may be
ascertained for such winding-up  prior to payment by the liquidator or otherwise
in respect thereto.

     (c) The obligations contained in paragraphs (a)(ii) and (b) of this Section
10.07 shall:

          (i)  constitute  separate and  independent  obligations of the Company
     from its other obligations under the Notes and this Indenture;

          (ii) give rise to separate and  independent  causes of action  against
     the Company;

          (iii) apply  irrespective  of any waiver or  extension  granted by any
     Holder or the Trustee from time to time; and

          (iv) continue in full force and effect notwithstanding any judgment or
     order or the filing of any proof of claim in the  winding-up of the Company
     for a liquidated sum in respect of amounts due hereunder  (other than under
     paragraph (b) above) or under any such judgment or order.

     Any such  deficiency  as  aforesaid  shall be deemed to  constitute  a loss
suffered  by the  Holders  or the  Trustee,  as the case may be, and no proof or
evidence of any actual loss shall be required by the Company or its liquidators.
In the case of paragraph (b) above,  the amount of such deficiency  shall not be
deemed to be reduced by any variation in rates of exchange occurring between the
said final date and the date of any liquidating distribution.

     (d) "Rate of  Exchange"  means the noon buying rate in the City of New York
as certified for customs purposes by the Federal Reserve Bank of New York on the
relevant date for cable  transfers in the Judgment  Currency  other than British
pounds  sterling  referred to in paragraphs  (a) and (b) above and shall include
any premiums and costs of exchange payable.

     (e) If the United Kingdom adopts the Euro, the  regulations of the European
Commission relating to the Euro shall apply to the Notes and this Indenture. The
circumstances  and consequences  described in this paragraph entitle neither the
Company nor any Holder to early  redemption,  rescission,  notice,  repudiation,
adjustment  or  renegotiation  of the terms and  conditions of the Notes or this
Indenture or to raise other defenses or to request any  compensation  claim, nor
will they affect any of the other obligations of the Company under the Notes and
this Indenture.

SECTION 10.08.  LEGAL HOLIDAYS.

     A  "Legal  Holiday"  is a  Saturday,  a Sunday  or a day on  which  banking
institutions  in the State of New York are not required to be open. If a payment
date is a Legal Holiday at a place of payment, payment may be made at that place
on the next  succeeding day that is not a Legal  Holiday,  and no interest shall
accrue for the intervening  period.  If any other operative date for purposes of
this  Indenture  shall occur on a Legal  Holiday  then for all purposes the next
succeeding day that is not a Legal Holiday shall be such operative date.

     A director, officer, employee or stockholder, as such, of the Company shall
not have any liability for any obligations of the Company under the Notes or the
Indenture  or for any  claim  based  on,  in  respect  of or by  reason  of such
obligations  or their  creation.  Each  Holder by  accepting  a Note  waives and
releases  all  such   liability.   The  waiver  and  release  are  part  of  the
consideration for the issue of the Notes.

     This  Indenture  may be executed by manual or  facsimile  signature  in any
number of counterparts and by the parties hereto in separate counterparts,  each

                        [FORM OF REVERSE OF INITIAL NOTE]

                                NTL INCORPORATED



                           9-1/2% Senior Note Due 2008

     1. Interest. NTL INCORPORATED,  a Delaware corporation (the "Company"),  is
the issuer of 9-1/2%  Senior  Notes Due 2008 (the  "Senior  Notes").  The Senior
Notes will accrue interest at a rate of 9-1/2% per annum.  The Company  promises
to pay  interest on the Senior  Notes in cash  semiannually  on each April 1 and
October  1,  commencing  on  October  1,  1998,  to  Holders  of  record  on the
immediately  preceding March 15 and September 15, respectively.  Interest on the
Senior  Notes will accrue from the most recent date to which  interest  has been
paid,  or if no interest has been paid,  from March 13, 1998.  Interest  will be
computed on the basis of a 360-day  year of twelve  30-day  months.  The Company
will pay interest on overdue  principal at the interest rate borne by the Senior
Notes,   compounded   semiannually,   and  it  shall  pay  interest  on  overdue
installments of interest  (without regard to any applicable grace period) at the
same interest  rate  compounded  semiannually.  Any interest paid on this Senior
Note shall be increased to the extent necessary to pay Additional Amounts as set
forth in this Senior Note.

     2.  Special  Interest.  The Holder of this  Senior  Note is entitled to the
benefits of the  Registration  Rights  Agreement  relating to the Senior  Notes,
dated as of March 13, 1998, between the Company and the Initial Purchasers party
thereto (the "Registration Rights Agreement").

     In the event that either (a) the Exchange Offer Registration  Statement (as
such term is defined in the Registration Rights Agreement) is not filed with the
SEC on or prior to the 90th day following  the date of original  issuance of the
Senior  Notes,  (b) the Exchange  Offer  Registration  Statement is not declared
effective prior to the 270th day following the date of original  issuance of the
Senior Notes (as such period may be extended in  accordance  with the SEC review
delay  provisions of the  Registration  Rights  Agreement) or (c) the Registered
Exchange Offer (as such term is defined in the Registration Rights Agreement) is
not  consummated or a Shelf  Registration  Statement (as such term is defined in
the Registration  Rights Agreement) is not declared effective on or prior to the
310th day following  the date of original  issuance of the Senior Notes (as such
period may be extended in accordance with the SEC review delay provisions of the
Registration  Rights  Agreement)  (each such event  referred  to in clauses  (a)
through (c) above, a "Registration Default"),  interest will accrue (in addition
to the stated  interest  on the Senior  Notes) from and  including  the next day
following  each of (i) such  90-day  period in the case of clause  (a) above and
(ii) such 270-day  period in the case of clause (b) above and (iii) such 310-day
period  in the case of  clause  (c)  above (in each of cases (b) and (c) as such
period is extended,  if applicable,  in the manner  aforesaid) (each such period
referred to in clauses (i)-(iii) above an "Accrual Period"), at a rate per annum
equal to 0.50% of the principal amount of the Senior Notes  (determined  daily).
The amount of such additional interest (the "Special Interest") will increase by
an  additional  0.50% of the  principal  amount with respect to each  subsequent
applicable Accrual Period until all Registration Defaults have been cured, up to
a maximum amount of Special  Interest of 1.50% per annum of the principal amount
(determined  daily).  In each case such  additional  interest will be payable in
cash  semiannually in arrears on each April 1 and October 1, commencing  October
1,  1998,  to  Holders  of  record  on the  immediately  preceding  March 15 and
September 15, respectively.  In the event that a Shelf Registration Statement is
declared effective  pursuant to the terms of the Registration  Rights Agreement,


                                       5
<PAGE>


if the Company fails to keep such Registration  Statement continuously effective
for the period required by the  Registration  Rights  Agreement,  then from such
time as the  Shelf  Registration  Statement  is no  longer  effective  until the
earlier of (i) the date that the Shelf  Registration  Statement  is again deemed
effective, (ii) the date that is the second anniversary of the original issuance
of the Senior  Notes or (iii) the date as of which all of the  Senior  Notes are
sold pursuant to the Shelf Registration Statement, Special Interest shall accrue
at a rate per annum equal to 0.50% of the  principal  amount of the Senior Notes
(1.00% thereof if the Shelf Registration Statement is no longer effective for 30
days or more) and shall be payable in cash semiannually in arrears on each April
1 and  October 1,  commencing  October 1, 1998,  to the Holders of record on the
immediately preceding March 15 and September 15, respectively.

     3.  Additional  Amounts.  This Section 3 shall apply only in the event that
the Company becomes,  or a successor to the Company is, a corporation  organized
or  existing  under  the  laws  of the  United  Kingdom,  the  Netherlands,  the
Netherlands  Antilles,  Bermuda or the Cayman Islands.  All payments made by the
Company on this Senior Note shall be made  without  deduction  for or on account
of, any and all present or future taxes,  duties,  assessments,  or governmental
charges of whatever  nature unless the deduction or  withholding  of such taxes,
duties,  assessments  or  governmental  charges is then  required by law. If any
deduction  or  withholding  for or on  account of any  present or future  taxes,
assessments  or  other   governmental   charges  of  the  United  Kingdom,   the
Netherlands,  the  Netherlands  Antilles,  Bermuda or the Cayman Islands (or any
political  subdivision or taxing authority thereof or therein) shall at any time
be  required  in respect of any  amounts  to be paid by the  Company  under this
Senior Note, the Company shall pay or cause to be paid such  additional  amounts
("Additional  Amounts")  as may be  necessary  in  order  that  the net  amounts
received  by a Holder of this Senior Note after such  deduction  or  withholding
shall be not less than the  amounts  specified  in this Senior Note to which the
Holder of this  Senior Note is  entitled;  provided,  however,  that the Company
shall not be  required  to make any  payment  of  Additional  Amounts  for or on
account of:

          (a) any tax,  assessment  or other  governmental  charge to the extent
     such  tax,  assessment  or other  governmental  charge  would not have been
     imposed  but for (i) the  existence  of any  present  or former  connection
     between such Holder (or between a fiduciary, settlor,  beneficiary,  member
     or  shareholder  of, or  possessor of a power over,  such  Holder,  if such
     Holder is an estate,  nominee,  trust,  partnership or corporation),  other
     than the holding of this  Senior Note or the receipt of amounts  payable in
     respect of this Senior Note, and the United Kingdom,  the Netherlands,  the
     Netherlands  Antilles,  Bermuda or the  Cayman  Islands  (or any  political
     subdivision  or taxing  authority  thereof or therein)  including,  without
     limitation, such Holder (or such fiduciary, settlor,  beneficiary,  member,
     shareholder  or  possessor)  being or  having  been a citizen  or  resident
     thereof or being or having  been  present  or engaged in trade or  business
     therein or having or having had a permanent  establishment  therein or (ii)
     the  presentation of this Senior Note (where  presentation is required) for
     payment on a date more than 30 days  after the date on which  such  payment
     became  due and  payable  or the  date on  which  payment  thereof  is duly
     provided for, whichever occurs later,  except to the extent that the Holder
     would have been  entitled to  Additional  Amounts had this Senior Note been
     presented on the last day of such period of 30 days;

          (b) any tax,  assessment or other governmental  charge that is imposed
     or withheld by reason of the failure to comply by the Holder of this Senior
     Note or, if different, the beneficial owner of the interest payable on this
     Senior Note, with a timely request of the Company  addressed to such Holder
     or beneficial  owner to provide  information,  documents or other  evidence
     concerning  the  nationality,  residence,  identity or connection  with the
     taxing jurisdiction of such Holder or beneficial owner which is required or
     imposed by a statute,  regulation or


                                       6
<PAGE>


     administrative  practice of the taxing  jurisdiction  as a precondition  to
     exemption from all or part of such tax, assessment or governmental charge;

          (c) any estate, inheritance,  gift, sales, transfer, personal property
     or similar tax, assessment or other governmental charge;

          (d)  any  tax,  assessment  or  other  governmental  charge  which  is
     collectible  otherwise  than by  withholding  from  payments  of  principal
     amount,  redemption  amount,  Change of Control  Payment or  interest  with
     respect to a Senior  Note or  withholding  from the  proceeds  of a sale or
     exchange of a Senior Note;

          (e) any tax,  assessment or other  governmental  charge required to be
     withheld  by any  Paying  Agent  from  any  payment  of  principal  amount,
     redemption amount,  Change of Control Payment or interest with respect to a
     Senior Note, if such payment can be made, and is in fact made, without such
     withholding by any other Paying Agent located inside the United States;

          (f) any tax,  assessment  or other  governmental  charge  imposed on a
     Holder that is not the beneficial owner of a Senior Note to the extent that
     the  beneficial  owner  would not have been  entitled to the payment of any
     such Additional  Amounts had the beneficial  owner directly held the Senior
     Note;

          (g) any combination of items (a), (b), (c), (d), (e) and (f) above;

nor  shall  Additional  Amounts  be paid  with  respect  to any  payment  of the
principal  of, or any  interest  on,  this  Senior  Note to any  Holder who is a
fiduciary or partnership or other than the sole beneficial owner of such payment
to the extent that a beneficiary  or settlor would not have been entitled to any
Additional  Amounts  had such  beneficiary  or  settlor  been the Holder of this
Senior Note. All references to principal  amount or interest on the Senior Notes
in the  Indenture  or the Senior  Notes  shall  include any  Additional  Amounts
payable to the Company pursuant to this Section 3.

     4. Method of Payment.  The Company  will pay  interest on the Senior  Notes
(except defaulted  interest) to the Persons who are registered Holders of Senior
Notes at the close of business on the record date for the next interest  payment
date even  though  Senior  Notes are  canceled  after the record  date and on or
before the  interest  payment  date.  Holders must  surrender  Senior Notes to a
Paying Agent to collect  principal  and premium  payments.  The Company will pay
principal,  premium, if any, and interest in money of the United Kingdom that at
the time of payment is legal  tender for  payment of public and  private  debts.
However,  the Company may pay principal,  premium, if any, and interest by check
payable in such money.  It may mail an interest  check to a holder's  registered
address. If a Holder so requests,  principal,  premium, if any, and interest may
be paid by wire transfer of immediately available funds to an account previously
specified in writing by such Holder to the Company and the Trustee.

     5. Paying  Agent and  Registrar.  The Trustee  will act as Paying Agent and
Registrar  in the City of New  York,  New York and in  London,  England.  Banque
Internationale  a  Luxembourg  S.A.  will act as Paying  Agent and  Registrar in
Luxembourg  as long as the  Senior  Notes  are  listed on the  Luxembourg  Stock
Exchange.  The Company may change any Paying  Agent or Registrar  without  prior
notice. The Company or any of its Affiliates may act in any such capacity.

     6. Indenture. The Company issued the Senior Notes under an Indenture, dated
as of March 13,  1998  (the  "Indenture"),  between  the  Company  and The Chase
Manhattan  Bank, as Trustee.  The terms of


                                       7
<PAGE>


the Senior Notes  include  those stated in the  Indenture and those made part of
the  Indenture  by the  Trust  Indenture  Act of 1939 (15 U.S.  Code  (Sections)
77aaa-77bbbb)  as in effect on the date of the  Indenture.  The Senior Notes are
subject to, and  qualified by, all such terms,  certain of which are  summarized
hereon,  and Holders are referred to the  Indenture and such Act for a statement
of such terms. The Senior Notes are unsecured general obligations of the Company
limited to  125,000,000  pounds  sterling  in  aggregate  principal  amount.

     7. Optional Redemption.  Except as provided in Section 8 hereof, the Senior
Notes  are not  redeemable  at the  Company's  option  prior to  April 1,  2003.
Thereafter,  the Senior Notes will be subject to redemption at the option of the
Company,  in  whole or in part,  upon  not less  than 30 nor more  than 60 days'
notice, at the redemption prices (expressed as percentages of principal amount )
set forth  below plus  accrued  and unpaid  interest  thereon to the  applicable
redemption date, if redeemed during the twelve-month period beginning on April 1

             2004........................ 103.167%
             2005........................ 101.583%
             2006 and thereafter......... 100.000%


     8.  Optional  Tax  Redemption.  (a) The Senior Notes may be redeemed at the
option of the Company,  in whole but not in part, upon not less than 30 nor more
than 60 days notice,  at any time at a redemption  price equal to the  principal
amount thereof plus accrued and unpaid interest to the date fixed for redemption
if after the date on which Section 3 of this Senior Note becomes applicable (the
"Relevant  Date")  there has occurred any change in or amendment to the laws (or
any  regulations  or  official  rulings  promulgated  thereunder)  of the United
Kingdom,  the  Netherlands,  the  Netherlands  Antilles,  Bermuda  or the Cayman
Islands (or any political  subdivision or taxing authority  thereof or therein),
or any change in or amendment to the official  application or  interpretation of
such laws, regulation or rulings (a "Change in Tax Law") which becomes effective
after the  Relevant  Date,  as a result of which the  Company  is or would be so
required on the next succeeding  Interest Payment Date to pay Additional Amounts
with  respect to the  Senior  Notes as  described  under  Section 3 hereof  with
respect to withholding taxes imposed by the United Kingdom, the Netherlands, the
Netherlands   Antilles,   Bermuda  or  the  Cayman  Islands  (or  any  political
subdivision or taxing  authority  thereof or therein) (a "Withholding  Tax") and
such  Withholding  Tax is  imposed at a rate that  exceeds  the rate (if any) at
which Withholding Tax was imposed on the Relevant Date, provided,  however, that
(i) this  paragraph  shall not apply to the extent that, at the Relevant Date it
was known or would  have  been  known had  professional  advice of a  nationally
recognized  accounting  firm  in  the  United  Kingdom,  the  Netherlands,   the
Netherlands  Antilles,  Bermuda or the Cayman Islands,  as the case may be, been
sought,  that a Change in Tax Law in the United Kingdom,  the  Netherlands,  the
Netherlands  Antilles,  Bermuda or the  Cayman  Islands  was to occur  after the
Relevant  Date,  (ii) no such notice of redemption  may be given earlier than 90
days prior to the  earliest  date on which the  Company  would be obliged to pay
such Additional  Amounts were a payment in respect of the Senior Notes then due,
(iii) at the time such notice of  redemption  is given,  such  obligation to pay
such Additional Amount remains in effect and (iv) the payment of such Additional
Amounts cannot be avoided by the use of any reasonable measures available to the
Company.

     The Senior  Notes may also be  redeemed,  in whole but not in part,  at any
time at a redemption  price equal to the principal  amount  thereof plus accrued
and unpaid  interest to the date fixed for


                                       8

redemption  if the Person  formed  after the Relevant  Date by a  consolidation,
amalgamation, reorganization or reconstruction (or other similar arrangement) of
the Company or the Person into which the  Company is merged  after the  Relevant
Date or to which the Company  conveys,  transfers or leases its  properties  and
assets after the Relevant Date  substantially  as an entirety  (collectively,  a
"Subsequent  Consolidation")  is required,  as a consequence of such  Subsequent
Consolidation and as a consequence of a Change in Tax Law in the United Kingdom,
the  Netherlands,  the  Netherlands  Antilles,  Bermuda  or the  Cayman  Islands
occurring  after the date of such  Subsequent  Consolidation  to pay  Additional
Amounts  with  respect  to Senior  Notes  with  respect  to  Withholding  Tax as
described  under Section 3 hereof and such  Withholding Tax is imposed at a rate
that exceeds the rate (if any) at which  Withholding  Tax was or would have been
imposed on the date of such Subsequent  Consolidation,  provided,  however, that
this  paragraph  shall  not  apply  to the  extent  that,  at the  date  of such
Subsequent  Consolidation it was known or would have been known had professional
advice of a nationally  recognized  accounting firm in the United  Kingdom,  the
Netherlands,  the Netherlands  Antilles,  Bermuda or the Cayman Islands,  as the
case may be, been sought,  that a Change in Tax Law in the United  Kingdom,  the
Netherlands,  the  Netherlands  Antilles,  Bermuda or the Cayman  Islands was to
occur after such date.

     The Company will also pay, or make available for payment, to Holders on the
Redemption  Date any  Additional  Amounts  (as  described,  but  subject  to the
exceptions  referred to, in Section 3 hereof) resulting from the payment of such
Redemption Price.

     9. Notice of  Redemption.  Notice of redemption  will be mailed at least 30
days but not more than 60 days before the redemption  date to each Holder of the
Senior  Notes to be  redeemed  at his  address  of record.  The Senior  Notes in
denominations larger than 1,000 pounds sterling may be redeemed in part but only
in integral multiples of 1,000 pounds sterling.  In the event of a redemption of
less  than  all of the  Senior  Notes,  the  Senior  Notes  will be  chosen  for
redemption by the Trustee in  accordance  with the  Indenture.  On and after the
redemption  date,  interest  ceases to accrue on the Senior Notes or portions of
them called for redemption.

     If this Senior Note is redeemed subsequent to a record date with respect to
any  interest  payment  date  specified  above and on or prior to such  interest
payment date, then any accrued interest will be paid to the Person in whose name
this Senior Note is registered at the close of business on such record date.

     10.  Mandatory  Redemption.  The  Company  will  not be  required  to  make
mandatory  redemption or  repurchase  payments with respect to the Senior Notes.
There are no sinking fund payments with respect to the Senior Notes.

     11.  Repurchase  at Option of  Holder.  (a) If there is a Change of Control
Triggering  Event,  the  Company  shall be  required to offer to purchase on the
Purchase Date all outstanding  Senior Notes at a purchase price equal to 101% of
the aggregate principal amount thereof,  plus accrued and unpaid interest to the
Purchase Date.  Holders of Senior Notes that are subject to an offer to purchase
will  receive a Change of Control  offer from the  Company  prior to any related
Purchase  Date and may elect to have such Senior  Notes or  portions  thereof in
authorized  denominations  purchased by completing the form entitled  "Option of
Holder to Elect Purchase" appearing below.

     (b) If the Company or a Restricted Subsidiary  consummates any Asset Sales,
and when the aggregate  amount of Excess  Proceeds from such Asset Sales exceeds
$15  million,  the  Company  shall be  required to make an offer (an "Asset Sale
Offer") to all holders of the Senior Notes and Other Qualified Notes to purchase
the  maximum  principal  amount  of  Senior  Notes  and  Other  Qualified  Notes
(determined  on a pro rata basis  according to the principal  amount or accreted
value,  as the case may be, of the Senior Notes and the Other  Qualified  Notes;
provided,  however,  that the asset sale offer must be


                                       9
<PAGE>


made first to the holders of the Applicable  Notes) that may be purchased out of
the Excess Proceeds,  if any,  remaining after the consummation of an asset sale
offer made to the holders of the  Applicable  Notes,  with respect to the Senior
Notes,  at an offer price in cash in an amount equal to 100% of the  outstanding
principal amount thereof plus accrued and unpaid  interest,  if any, to the date
fixed for the closing of such offer. To the extent that the aggregate  principal
amount or accreted value, as the case may be, of Senior Notes,  Applicable Notes
and Other Qualified Notes tendered  pursuant to an Asset Sale Offer is less than
the Excess Proceeds,  the Company may use such deficiency for general  corporate
purposes.  If the aggregate  principal amount or accreted value, as the case may
be, of Senior Notes and Other  Qualified  Notes  surrendered by holders  thereof
exceeds the amount of Excess Proceeds,  if any, remaining after the consummation
of an asset  sale  offer made to  holders  of the  Applicable  Notes,  then such
remaining  Excess  Proceeds  will be allocated  pro rata  according to principal
amount or accreted value, as the case may be, to the Senior Notes and each issue
of the Other Qualified Notes and, the Trustee will select the Senior Notes to be
purchased in accordance with Section  3.09(e) of the Indenture.  Upon completion
of such offer to purchase, the amount of Excess Proceeds will be reset at zero.

     12. Denominations,  Transfer,  Exchange. The Senior Notes are in registered
form,  without  coupons,  in denominations of 1,000 pounds sterling and integral
multiples  of 1,000  pounds  sterling.  The  transfer  of  Senior  Notes  may be
registered, and Senior Notes may be exchanged, as provided in the Indenture. The
Registrar  may require a Holder,  among  other  things,  to furnish  appropriate
endorsements  and transfer  documents  and to pay any taxes and fees required by
law or permitted by the  Indenture.  The Registrar need not exchange or register
the  transfer  of any  Senior  Note or  portion of a Senior  Note  selected  for
redemption  (except the unredeemed  portion of any Senior Note being redeemed in
part).  Also,  it need not  exchange or register the transfer of any Senior Note
for a period of 15 days before a selection of Senior Notes to be redeemed.

     13. Persons Deemed Owners. Except as provided in paragraph 4 of this Senior
Note, the registered Holder of a Senior Note may be treated as its owner for all
purposes.

     14.  Unclaimed  Money.  If money for the payment of  principal  or interest
remains  unclaimed for two years, the Trustee and the Paying Agent shall pay the
money back to the Company at its written request.  After that, Holders of Senior
Notes  entitled  to the money must look to the  Company  for  payment  unless an
abandoned  property  law  designates  another  Person and all  liability  of the
Trustee and such Paying Agent with respect to such money shall cease.

     15.  Defaults  and  Remedies.  The  Senior  Notes  shall have the Events of
Default  set  forth  in  Section  6.01  of the  Indenture.  Subject  to  certain
limitations in the  Indenture,  if an Event of Default occurs and is continuing,
the Trustee by notice to the Company or the Holders of at least 25% in aggregate
principal amount of the then  outstanding  Senior Notes by notice to the Company
and  the  Trustee  may  declare  all the  Senior  Notes  to be due  and  payable
immediately, except that in the case of an Event of Default arising from certain
events of bankruptcy or insolvency, all unpaid principal and interest accrued on
the Senior Notes shall become due and payable immediately without further action
or notice.  The Holders of a majority in  principal  amount of the Senior  Notes
then  outstanding by written  notice to the Trustee may rescind an  acceleration
and its  consequences if the rescission  would not conflict with any judgment or
decree and if all existing  Events of Default  have been cured or waived  except
nonpayment  of principal or interest  that has become due solely  because of the
acceleration.  Holders may not enforce the  Indenture or the Senior Notes except
as  provided  in the  Indenture.  Subject to certain  limitations,  Holders of a
majority in principal amount of the then  outstanding  Senior Notes issued under
the Indenture may direct the Trustee in its exercise of any trust or power.  The
Company must furnish annually compliance  certificates to the Trustee. The above
description  of Events of Default


                                       10
<PAGE>


and remedies is qualified by reference, and subject in its entirety, to the more
complete description thereof contained in the Indenture.

     16. Amendments, Supplements and Waivers. Subject to certain exceptions, the
Indenture or the Senior Notes may be amended or supplemented with the consent of
the Holders of at least a majority in principal  amount of the then  outstanding
Senior Notes (including  consents  obtained in connection with a tender offer or
exchange  offer for Senior Notes),  and any existing  default may be waived with
the  consent  of the  Holders  of a  majority  in  principal  amount of the then
outstanding  Senior Notes.  Without the consent of any Holder,  the Indenture or
the Senior  Notes may be amended  among  other  things,  to cure any  ambiguity,
defect or inconsistency,  to provide for assumption of the Company's obligations
to Holders,  to make any change that does not adversely affect the rights of any
Holder  or to  qualify  the  Indenture  under  the  TIA or to  comply  with  the
requirements of the SEC in order to maintain the  qualification of the Indenture
under the TIA.

     17. Restrictive Covenants. The Indenture imposes certain limitations on the
ability of the Company and its  Subsidiaries  to, among other things,  engage in
certain  transactions  with Affiliates,  incur additional  indebtedness and make
payments in respect of Capital Stock. The limitations are subject to a number of
important qualifications and exceptions.

     18. Trustee  Dealings with the Company.  The Trustee,  in its individual or
any other  capacity  may become the owner or pledgee of the Senior Notes and may
otherwise  deal with the Company or an  Affiliate  with the same rights it would
have, as if it were not Trustee,  subject to certain limitations provided for in
the Indenture and in the TIA. Any Agent may do the same with like rights.

     19.  No  Recourse  Against  Others.  A  director,   officer,   employee  or
stockholder,  as such,  of the  Company  shall  not have any  liability  for any
obligations  of the Company  under the Senior Notes or the  Indenture or for any
claim  based  on,  in  respect  of or by  reason  of such  obligations  or their
creation.  Each Holder of the Senior Notes by accepting a Senior Note waives and
releases  all  such   liability.   The  waiver  and  release  are  part  of  the
consideration for the issue of the Senior Notes.

     20.  Governing Law. THE INTERNAL LAWS OF THE STATE OF NEW YORK SHALL GOVERN
THE INDENTURE AND THE SENIOR NOTES WITHOUT  REGARD TO CONFLICT OF LAW PROVISIONS
THEREOF.

     21. Authentication. The Senior Notes shall not be valid until authenticated
by  the  manual  signature  of  an  authorized  officer  of  the  Trustee  or an
authenticating agent.

     22.  Abbreviations.  Customary  abbreviations  may be used in the name of a
Holder or an  assignee,  such as:  TEN COM (=  tenants  in  common),  TEN ENT (=
tenants by the  entireties),  JT TEN (= joint tenants with right of survivorship
and not as tenants in common), CUST (- Custodian),  and UGMA (= Uniform Gifts to
Minors Act).

     The Company  will  furnish to any Holder of the Senior  Notes upon  written
request and without charge a copy of the Indenture. Request may be made to:

                       (FORM OF REVERSE OF EXCHANGE NOTE)

                                NTL INCORPORATED

                      9-1/2% Series B Senior Note Due 2008

     1. Interest. NTL INCORPORATED,  a Delaware corporation (the "Company"),  is
the issuer of 9-1/2%  Series B Senior Notes Due 2008 (the "Senior  Notes").  The
Senior  Notes will accrue  interest  at a rate of 9-1/2% per annum.  The Company
promises to pay interest on the Senior Notes in cash  semiannually on each April
1 and  October  1,  commencing  October  1,  1998,  to  Holders of record on the
immediately  preceding March 15 and September 15,  respectively,  at the rate of
9-1/2% per annum.  Interest on the Senior Notes will accrue from the most recent
date to which  interest has been paid on the  Company's  9-1/2% Senior Notes Due
2008, or the Senior Notes,  as the case may be, or if no interest has been paid,
from March 13, 1998. Interest will be computed on the basis of a 360-day year of
twelve  30-day  months.  The Company will pay interest on overdue  principal and
premium,  if any, at the  interest  rate borne by the Senior  Notes,  compounded
semiannually,  and it shall pay  interest  on overdue  installments  of interest
(without  regard to any  applicable  grace  period)  at the same  interest  rate
compounded  semiannually.  Any  interest  paid  on this  Senior  Note  shall  be
increased to the extent necessary to pay Additional Amounts as set forth in this
Senior Note.

     2.  Additional  Amounts.  This Section 2 shall apply only in the event that
the Company becomes,  or a successor to the Company is, a corporation  organized
or  existing  under  the  laws  of the  United  Kingdom,  the  Netherlands,  the
Netherlands  Antilles,  Bermuda or the Cayman Islands.  All payments made by the
Company on this Senior Note shall be made  without  deduction  for or on account
of, any and all present or future taxes,  duties,  assessments,  or governmental
charges  of  whatever  nature  unless  the  deduction  of  such  taxes,  duties,
assessments or governmental charges is then required by law. If any deduction or
withholding  for or on account of any present or future  taxes,  assessments  or
other  governmental  charges  of  the  United  Kingdom,  the  Netherlands,   the
Netherlands   Antilles,   Bermuda  or  the  Cayman  Islands  (or  any  political
subdivision or taxing authority  thereof or taxing authority thereof or therein)
shall  at any time be  required  in  respect  of any  amounts  to be paid by the
Company  under this Senior Note,  the Company shall pay or cause to be paid such
additional amounts ("Additional  Amounts") as may be necessary in order that the
net amounts  received by a Holder of this  Senior Note after such  deduction  or
withholding  shall be not less than the amounts specified in this Senior Note to
which the Holder of this Senior Note is entitled;  provided,  however,  that the
Company shall not be required to make any payment of  Additional  Amounts for or
on account of:

          (a) any tax,  assessment  or other  governmental  charge to the extent
     such  tax,  assessment  or other  governmental  charge  would not have been
     imposed  but for (i) the  existence  of any  present  or former  connection
     between such Holder (or between a fiduciary, settlor,  beneficiary,  member
     or  shareholder  of, or  possessor of a power over,  such  Holder,  if such
     Holder is an estate,  nominee,  trust,  partnership or corporation),  other
     than the holding of this  Senior Note or the receipt of amounts  payable in
     respect of this Senior  Note,  the United  Kingdom,  the  Netherlands,  the
     Netherlands  Antilles,  Bermuda  or the  Cayman  Islands  or any  political
     subdivision  or taxing  authority  thereof or therein,  including,  without
     limitation, such Holder (or such fiduciary, settlor,  beneficiary,  member,
     shareholder  or  possessor)  being or  having  been a citizen  or  resident
     thereof or being or having  been  present  or engaged in trade or  business
     therein or having or having had a


                                       4
<PAGE>


     permanent  establishment  therein or (ii) the  presentation  of this Senior
     Note (where  presentation  is required)  for payment on a date more than 30
     days after the date on which  such  payment  became due and  payable or the
     date on which payment thereof is duly provided for, whichever occurs later,
     except to the extent that the Holder would have been entitled to Additional
     Amounts had this Senior Note been  presented on the last day of such period
     of 30 days;

          (b) any tax,  assessment or other governmental  charge that is imposed
     or withheld by reason of the failure to comply by the Holder of this Senior
     Note or, if different, the beneficial owner of the interest payable on this
     Senior Note, with a timely request of the Company  addressed to such Holder
     or beneficial  owner to provide  information,  documents or other  evidence
     concerning  the  nationality,  residence,  identity or connection  with the
     taxing jurisdiction of such Holder or beneficial owner which is required or
     imposed by a statute,  regulation or administrative  practice of the taxing
     jurisdiction  as a precondition  to exemption from all or part of such tax,
     assessment or governmental charge;

          (c) any estate, inheritance,  gift, sales, transfer, personal property
     or similar tax, assessment or other governmental charge;

          (d)  any  tax,  assessment  or  other  governmental  charge  which  is
     collectible  otherwise  than by  withholding  from  payments  of  principal
     amount,  redemption  amount,  Change of Control  Payment or  interest  with
     respect to a Senior  Note or  withholding  from the  proceeds  of a sale or
     exchange of a Senior Note;

          (e) any tax,  assessment or other  governmental  charge required to be
     withheld  by any  Paying  Agent  from  any  payment  of  principal  amount,
     redemption amount,  Change of Control Payment or interest with respect to a
     Senior Note, if such payment can be made, and is in fact made, without such
     withholding by any other Paying Agent located inside the United States;

          (f) any tax,  assessment  or other  governmental  charge  imposed on a
     Holder that is not the beneficial owner of a Senior Note to the extent that
     the  beneficial  owner  would not have been  entitled to the payment of any
     such Additional  Amounts had the beneficial  owner directly held the Senior
     Note;

          (g) any combination of items (a), (b), (c), (d), (e) and (f) above;

nor  shall  Additional  Amounts  be paid  with  respect  to any  payment  of the
principal  of, or any  interest  on,  this  Senior  Note to any  Holder who is a
fiduciary or partnership or other than the sole beneficial owner of such payment
to the extent that a beneficiary  or settlor would not have been entitled to any
Additional  Amounts  had such  beneficiary  or  settlor  been the Holder of this
Senior Note. All references to principal  amount or interest on the Senior Notes
in the  Indenture  or the Senior  Notes  shall  include any  Additional  Amounts
payable to the Company pursuant to this Section 2.

     3. Method of Payment.  The Company  will pay  interest on the Senior  Notes
(except defaulted  interest) to the Persons who are registered Holders of Senior
Notes at the close of business on the record date for the next interest  payment
date even  though  Senior  Notes are  canceled  after the record  date and on or
before the  interest  payment  date.  Holders must  surrender  Senior Notes to a
Paying Agent to collect  principal  and premium  payments.  The Company will pay
principal,  premium, if any, and interest in money of the United Kingdom that at
the time of payment is legal  tender for  payment of public and  private  debts.
However,  the Company may pay principal,  premium, if any, and interest by check
payable


                                       5
<PAGE>


in such money. It may mail an interest check to a holder's  registered  address.
If a Holder so requests, principal, premium, if any, and interest may be paid by
wire transfer of immediately  available funds to an account previously specified
in writing by such Holder to the Company and the Trustee.

     4. Paying  Agent and  Registrar.  The Trustee  will act as Paying Agent and
Registrar in the City of New York and in London,  England. Banque Internationale
a Luxembourg  S.A.  will act as Paying Agent and Registrar in Luxembourg as long
as the Senior Notes are listed on the Luxembourg Stock Exchange. The Company may
change any Paying Agent or Registrar without prior notice. The Company or any of
its Affiliates may act in any such capacity.

     5. Indenture. The Company issued the Senior Notes under an indenture, dated
as of March 13,  1998  (the  "Indenture"),  between  the  Company  and The Chase
Manhattan  Bank, as Trustee.  The terms of the Senior Notes include those stated
in the Indenture and those made part of the Indenture by the Trust Indenture Act
of 1939 (15 U.S. Code (Sections)  77aaa-77bbbb)  as in effect on the date of the
Indenture.  The Senior Notes are subject to, and  qualified  by, all such terms,
certain  of which  are  summarized  hereon,  and  Holders  are  referred  to the
Indenture  and such Act for a  statement  of such  terms.  The Senior  Notes are
unsecured  general  obligations  of the Company  limited to  125,000,000  pounds
sterling in aggregate principal amount.

     6. Optional Redemption.  Except as provided in Section 7 herein, the Senior
Notes  are not  redeemable  at the  Company's  option  prior to  April 1,  2003.
Thereafter,  the Senior Notes will be subject to redemption at the option of the
Company,  in  whole or in part,  upon  not less  than 30 nor more  than 60 days'
notice,  at the redemption prices (expressed as percentages of principal amount)
set forth  below plus  accrued  and unpaid  interest  thereon to the  applicable
redemption date, if redeemed during the twelve-month period beginning on April 1
of the years indicated below:



             Year                             Percentage
             2003 ........................... 104.750%
             2004............................ 103.167%
             2005............................ 101.583%
             2006 and thereafter............. 100.000%


     7.  Optional  Tax  Redemption.  (a) The Senior Notes may be redeemed at the
option of the Company,  in whole but not in part, upon not less than 30 nor more
than 60 days notice,  at any time at a redemption  price equal to the  principal
amount thereof plus accrued and unpaid interest to the date fixed for redemption
if after the date on which Section 2 of this Senior Note becomes applicable (the
"Relevant  Date")  there has occurred any change in or amendment to the laws (or
any  regulations  or  official  rulings  promulgated  thereunder)  of the United
Kingdom,  the  Netherlands,  the  Netherlands  Antilles,  Bermuda  or the Cayman
Islands (or any political  subdivision or taxing authority  thereof or therein),
or any change in or amendment to the official  application or  interpretation of
such  laws,  regulations  or  rulings  (a  "Change  in Tax Law")  which  becomes
effective  after the Relevant Date, as a result of which the Company is or would
be so required on the next  succeeding  Interest  Payment Date to pay Additional
Amounts with respect to the Senior  Notes as  described  under  Section 2 hereof
with  respect  to  withholding   taxes  imposed  by  the  United  Kingdom,   the
Netherlands,  the  Netherlands  Antilles,  Bermuda or the Cayman Islands (or any
political  subdivision or taxing  authority  thereof or therein) (a "Withholding
Tax') and such  Withholding  Tax is imposed at a rate that  exceeds the rate (if
any) at which


                                       6
<PAGE>


Withholding Tax was imposed on the Relevant Date,  provided,  however,  that (i)
this  paragraph  shall not apply to the extent that, at the Relevant Date it was
known  or  would  have  been  known  had  professional  advice  of a  nationally
recognized  accounting  firm  in  the  United  Kingdom,  the  Netherlands,   the
Netherlands  Antilles,  Bermuda or the Cayman Islands,  as the case may be, been
sought,  that a change in Tax Law in the United Kingdom,  the  Netherlands,  the
Netherlands  Antilles,  Bermuda or the  Cayman  Islands  was to occur  after the
Relevant  Date,  (ii) no such notice of redemption  may be given earlier than 90
days prior to the  earliest  date on which the  Company  would be obliged to pay
such Additional  Amounts were a payment in respect of the Senior Notes then due,
(iii) at the time such notice of  redemption  is given,  such  obligation to pay
such Additional Amount remains in effect and (iv) the payment of such Additional
Amounts cannot be avoided by the use of any reasonable measures available to the
Company.

     (b) The Senior Notes may also be redeemed, in whole but not in part, at any
time at a redemption  price equal to the principal  amount  thereof plus accrued
and unpaid  interest to the date fixed for redemption if the Person formed after
the  Relevant  Date  by  a  consolidation,   amalgamation,   reorganization   or
reconstruction (or other similar  arrangement) of the Company or the Person into
which the  Company is merged  after the  Relevant  Date or to which the  Company
conveys,  transfers or leases its  properties and assets after the Relevant Date
substantially as an entirety  (collectively,  a "Subsequent  Consolidation")  is
required, as a consequence of such Subsequent Consolidation and as a consequence
of a Change in Tax Law in the United Kingdom,  the Netherlands,  the Netherlands
Antilles,  Bermuda  or the  Cayman  Islands  occurring  after  the  date of such
Subsequent  Consolidation to pay Additional Amounts with respect to Senior Notes
with respect to  Withholding  Tax as described  under  Section 2 hereof and such
Withholding  Tax is  imposed at a rate that  exceeds  the rate (if any) at which
Withholding  Tax was or would have been  imposed on the date of such  Subsequent
Consolidation,  provided,  however,  that this paragraph  shall not apply to the
extent that, at the date of such Subsequent  Consolidation it was known or would
have been known had professional  advice of a nationally  recognized  accounting
firm in the United Kingdom, the Netherlands,  the Netherlands Antilles,  Bermuda
or the Cayman Islands, as the case may be, been sought, that a Change in Tax Law
in the United Kingdom, the Netherlands, the Netherlands Antilles, Bermuda or the
Cayman Islands was to occur after such date.

     The Company will also pay, or make available for payment, to Holders on the
Redemption  Date any  Additional  Amounts  (as  described,  but  subject  to the
exceptions  referred to, in Section 2 hereof) resulting from the payment of such
Redemption Price.

     8. Notice of  Redemption.  Notice of redemption  will be mailed at least 30
days but not more than 60 days before the redemption  date to each Holder of the
Senior  Notes to be  redeemed  at his  address  of record.  The Senior  Notes in
denominations larger than 1,000 pounds sterling may be redeemed in part but only
in integral multiples of 1,000 pounds sterling.  In the event of a redemption of
less  than  all of the  Senior  Notes,  the  Senior  Notes  will be  chosen  for
redemption by the Trustee in  accordance  with the  Indenture.  On and after the
redemption  date,  interest  ceases to accrue on the Senior Notes or portions of
them called for  redemption.  If this Senior  Note is redeemed  subsequent  to a
record date with respect to any interest  payment date specified above and on or
prior to such interest  payment date, then any accrued  interest will be paid to
the Person in whose name this Senior Note is registered at the close of business
on such record date.

     9. Mandatory Redemption. The Company will not be required to make mandatory
redemption or repurchase payments with respect to the Senior Notes. There are no
sinking fund payments with respect to the Senior Notes.

     10.  Repurchase  at Option of  Holder.  (a) If there is a Change of Control
Triggering  Event,  the  Company  shall be  required to offer to purchase on the
Purchase Date all outstanding  Senior Notes at a


                                       7
<PAGE>


purchase price equal to 101% of the aggregate  principal  amount  thereof,  plus
accrued and unpaid  interest to the Purchase Date.  Holders of Senior Notes that
are subject to an offer to purchase  will receive a Change of Control offer from
the Company prior to any related Purchase Date and may elect to have such Senior
Notes or portions  thereof in authorized  denominations  purchased by completing
the form entitled "Option of Holder to Elect Purchase" appearing below.

     (b) If the Company or a Restricted Subsidiary  consummates any Asset Sales,
and when the aggregate  amount of Excess  Proceeds from such Asset Sales exceeds
$15  million,  the  Company  shall be  required to make an offer (an "Asset Sale
Offer") to all holders of the Senior Notes and Other Qualified Notes to purchase
the  maximum  principal  amount  of  Senior  Notes  and  other  Qualified  Notes
(determined  on a pro rata basis  according to the principal  amount or accreted
value,  as the case may be, of the Senior Notes and the Other  Qualified  Notes;
provided,  however,  that the asset sale offer must be made first to the holders
of the Applicable  Notes) that may be purchased out of the Excess  Proceeds,  if
any, remaining after the consummation of an asset sale offer made to the holders
of the Applicable  Notes with respect to the Senior Notes,  at an offer price in
cash in an amount equal to 100% of the outstanding principal amount thereof plus
accrued and unpaid  interest,  if any, to the date fixed for the closing of such
offer. To the extent that the aggregate  principal  amount or accreted value, as
the case may be, of Senior Notes,  Applicable  Notes and Other  Qualified  Notes
tendered  pursuant to an Asset Sale Offer is less than the Excess Proceeds,  the
Company may use such deficiency for general corporate purposes. If the aggregate
principal  amount or  accreted  value,  as the case may be, of Senior  Notes and
Other  Qualified  Notes  surrendered  by holders  thereof  exceeds the amount of
Excess Proceeds, if any, remaining after the consummation of an asset sale offer
made to the holders of the Applicable  Notes, then any remaining Excess Proceeds
will be allocated pro rata according to principal  amount or accreted  value, as
the case may be, to the Senior Notes and each issue of the Other Qualified Notes
and, the Trustee will select the Senior Notes to be purchased in accordance with
Section 3.09(e) of the Indenture. Upon completion of such offer to purchase, the
amount of Excess Proceeds will be reset at zero.

     11. Denominations,  Transfer,  Exchange. The Senior Notes are in registered
form,  without  coupons,  in denominations of 1,000 pounds sterling and integral
multiples  of 1,000  pounds  sterling.  The  transfer  of  Senior  Notes  may be
registered, and Senior Notes may be exchanged, as provided in the Indenture. The
Registrar  may require a Holder,  among  other  things,  to furnish  appropriate
endorsements  and transfer  documents  and to pay any taxes and fees required by
law or permitted by the  Indenture.  The Registrar need not exchange or register
the  transfer  of any  Senior  Note or  portion of a Senior  Note  selected  for
redemption  (except the unredeemed  portion of any Senior Note being redeemed in
part).  Also,  it need not  exchange or register the transfer of any Senior Note
for a period of 15 days before a selection of Senior Notes to be redeemed.

     12. Persons Deemed Owners. Except as provided in paragraph 3 of this Senior
Note, the registered Holder of a Senior Note may be treated as its owner for all
purposes.

     13.  Unclaimed  Money.  If money for the payment of  principal  or interest
remains  unclaimed for two years, the Trustee and the Paying Agent shall pay the
money back to the Company at its written request.  After that, Holders of Senior
Notes  entitled  to the money must look to the  Company  for  payment  unless an
abandoned  property  law  designates  another  Person and all  liability  of the
Trustee and such Paying Agent with respect to such money shall cease.

     14.  Defaults  and  Remedies.  The  Senior  Notes  shall have the Events of
Default  as set forth in  Section  6.01 of the  Indenture.  Subject  to  certain
limitations in the  Indenture,  if an Event of Default occurs and is continuing,
the Trustee by notice to the Company or the Holders of at least 25% in aggregate
principal amount of the then  outstanding  Senior Notes by notice to the Company
and  the


                                       8
<PAGE>


Trustee  may declare  all the Senior  Notes to be due and  payable  immediately,
except that in the case of an Event of Default  arising from  certain  events of
bankruptcy  or  insolvency,  all unpaid  principal  and interest  accrued on the
Senior Notes shall become due and payable  immediately without further action or
notice.  The Holders of a majority in principal  amount of the Senior Notes then
outstanding by written notice to the Trustee may rescind an acceleration and its
consequences  if the  rescission  would not conflict with any judgment or decree
and if all  existing  Events  of  Default  have  been  cured  or  waived  except
nonpayment  of principal or interest  that has become due solely  because of the
acceleration.  Holders  may not  enforce the  Indenture  or the Senior  Notes as
provided in the Indenture. Subject to certain limitations, Holders of a majority
in  principal  amount of the then  outstanding  Senior  Notes  issued  under the
Indenture  may direct the  Trustee in its  exercise  of any trust or power.  The
Company must furnish annually compliance  certificates to the Trustee. The above
description  of Events of Default and remedies is qualified  by  reference,  and
subject in its entirety,  to the more complete  description thereof contained in
the Indenture.

     15. Amendments, Supplements and Waivers. Subject to certain exceptions, the
Indenture or the Senior Notes may be amended or supplemented with the consent of
the Holders of at least a majority in principal  amount of the then  outstanding
Senior Notes (including  consents  obtained in connection with a tender offer or
exchange  offer for Senior Notes),  and any existing  default may be waived with
the  consent  of the  Holders  of a  majority  in  principal  amount of the then
outstanding  Senior Notes.  Without the consent of any Holder,  the Indenture or
the Senior  Notes may be amended  among  other  things,  to cure any  ambiguity,
defect or inconsistency,  to provide for assumption of the Company's obligations
to Holders,  to make any change that does not adversely affect the rights of any
Holder  or to  qualify  the  Indenture  under  the  TIA or to  comply  with  the
requirements of the SEC in order to maintain the  qualification of the Indenture
under the TIA.

     16. Restrictive Covenants. The Indenture imposes certain limitations on the
ability of the Company and its  Subsidiaries  to, among other things,  engage in
certain  transactions  with Affiliates,  incur additional  Indebtedness and make
payments in respect of Capital Stock. The limitations are subject to a number of
important qualifications and exceptions.

     17. Trustee  Dealings with the Company.  The Trustee,  in its individual or
any other  capacity  may become the owner or pledgee of the Senior Notes and may
otherwise  deal with the Company or an  Affiliate  with the same rights it would
have, as if it were not Trustee,  subject to certain limitations provided for in
the Indenture and in the TIA. Any Agent may do the same with like rights.

     18.  No  Recourse  Against  Others.  A  director,   officer,   employee  or
stockholder,  as such,  of the  Company  shall  not have any  liability  for any
obligations  of the Company  under the Senior Notes or the  Indenture or for any
claim  based  on,  in  respect  of or by  reason  of such  obligations  or their
creation.  Each Holder of the Senior Notes by accepting a Senior Note waives and
releases  all  such   liability.   The  waiver  and  release  are  part  of  the
consideration for the issue of the Senior Notes.

     19.  Governing Law. THE INTERNAL LAWS OF THE STATE OF NEW YORK SHALL GOVERN
THE INDENTURE AND THE SENIOR NOTES WITHOUT  REGARD TO CONFLICT OF LAW PROVISIONS
THEREOF.

     20. Authentication. The Senior Notes shall not be valid until authenticated
by  the  manual  signature  of  an  authorized  officer  of  the  Trustee  or an
authenticating agent.

            Re: NTL Incorporated 9-1/2% Senior Notes
                Due 2008 (the "Senior Notes")


     Reference is hereby made to the Indenture,  dated as of March 13, 1998 (the
"Indenture"), between NTL Incorporated, as Issuer, and The Chase Manhattan Bank,
as Trustee.

     This letter relates to [ ] pounds sterling  aggregate  principal  amount of
Senior Notes which are held in the form of the [Rule 144A Global Note (CUSIP No.
)] with the Depositary in the name of [name of transferor] (the "Transferor") to
effect the transfer of the Senior Notes in exchange for an equivalent beneficial
interest in the Regulation S Global Notes.

     In connection  with such request,  the Transferor  does hereby certify that

forth in the Senior Notes and (i) with respect to transfers  made in reliance on
Regulation S, does hereby certify that:

          (1) the  offer of the  Senior  Notes  was not made to a Person  in the
     United States;

          (2) the transaction was executed in, on or through the facilities of a
     designated  offshore  securities  market and neither the Transferor nor any
     Person  acting on its behalf knows that the  transaction  was  pre-arranged
     with a buyer in the United States;

          (3) no directed selling efforts have been made in contravention of the
     requirements of Rule 903(b) or 904(b) of Regulation S, as applicable; and

          (4) the  transaction  is not part of a plan or  scheme  to  evade  the

     In  connection  with such  request,  and in respect of such Senior Notes we
confirm that:

     1. We  understand  that the  Senior  Notes  were  originally  offered  in a
transaction  not involving  any public  offering in the United States within the
meaning of the United States Securities Act of 1933, as amended (the "Securities
Act"),  that the Senior Notes have not been registered  under the Securities Act
and that (A) the Senior  Notes may be  offered,  resold,  pledged  or  otherwise
transferred  only  (i) to a  Person  who the  seller  reasonably  believes  is a
"qualified  institutional  buyer" (as defined in Rule 144A under the  Securities
Act) in a transaction  meeting the  requirements  of Rule 144A, in a transaction
meeting the  requirements  of Rule 144 under the Securities Act, to a Person who
the seller  reasonably  believes is an institutional  "accredited  investor" (as
defined in Rule 501(a)(1),  (2), (3) or (7) of Regulation D under the Securities
Act),  outside the United States in a transaction  meeting the  requirements  of
Rule 903 or 904 of Regulation S under the Securities  Act or in accordance  with
another exemption from the registration  requirements of the Securities Act (and
based  upon an opinion of  counsel  if the  Company  so  requests),  (ii) to the
Company,  (iii) pursuant to any other available  exemption from  registration or
(iv)  pursuant to an effective  registration  statement,  and, in each case,  in
accordance with any applicable securities laws of any state of the United States
or any  other  applicable  jurisdiction  and (B) the  purchaser  will,  and each
subsequent Holder is required to, notify any subsequent purchaser from it of the
resale restrictions set forth in (A) above.

     2. We are a corporation,  partnership or other entity having such knowledge
and experience in financial and business  matters as to be capable of evaluating
the merits and risks of an investment  in the Senior  Notes,  and we are (or any
account for which we are purchasing under paragraph 4 below is) an

institutional  "accredited  investor" as defined in Rule 501(a)(1),  (2), (3) or
(7) under the  Securities  Act,  able to bear the economic  risk of our proposed
investment in the Notes.

     3. We are  acquiring  the Senior Notes for our own account (or for accounts
as to which we exercise sole  investment  discretion and have authority to make,
and do make, the statements contained in this letter) and not with a view to any
distribution of the Senior Notes,  subject,  nevertheless,  to the understanding
that the disposition of our property shall at all times be and remain within our
control.

Notes is,  purchasing  Senior Notes having an aggregate  principal amount of not
less than 100,000 pounds sterling.

     5. We  understand  that (a) the  Senior  Notes will be  delivered  to us in
