SECTION 2.01. FORM AND DATING.

     (a)  General.   The  Initial  Notes  and  the  Trustee's   certificate   of

the Company and the Trustee,  by their execution and delivery of this Indenture,

to the extent any provision of any Note conflicts with the express provisions of
this   Indenture,   the  provisions  of  this  Indenture  shall  govern  and  be
controlling.

     (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


                                       16
<PAGE>


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 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


                                       17
<PAGE>


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).

     (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.


                                       18

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 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


                                       19
<PAGE>


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
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


                                       20
<PAGE>


     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 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


                                       21
<PAGE>


     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.

          (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


                                       22
<PAGE>


     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  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  certified  Note  shall  be  free  from  any
     restriction on transfer (other than such as are solely attributable to such
     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.


                                       23
<PAGE>


     (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.

     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.


                                       24

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.

     (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.


                                       25
<PAGE>


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.

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

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.

<PAGE>


     (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

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

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.

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


                                       27

     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 Accreted
Value or 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;

          (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;


                                       28
<PAGE>


          (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  contain  all  instructions  and
materials necessary to enable such Holders to tender Notes pursuant to the Asset
Sale Offer or the Purchase Offer, as the case may be.

(10)  calendar days after the Purchase  Date) mail or deliver to each  tendering
Holder an amount  equal to the  purchase  price of the  Notes  tendered  by such
Holder and accepted by the Company for purchase,  and the Trustee shall promptly

     (g) For the purposes of  calculating  the  allocation  of available  Excess
Proceeds  to the Notes  and each  issue of Other  Qualified  Notes on a pro rata
basis according to accreted value or principal  amount,  as the case may be, the
relevant  Accreted  Value or  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  Accreted  Value  or
               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.

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

the Notes on the dates  and in the  manner  provided  in the  Notes.  Principal,
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
that date money  designated for and sufficient to pay all principal and interest
then due.  To the extent  lawful,  the  Company  shall pay  interest  (including
post-petition  interest in any proceeding  under any Bankruptcy  Law) on (i) the
overdue  Accreted Value of the Notes,  if prior to April 1, 2003, or the overdue

(without  regard to any  applicable  grace period) at the same rate,  compounded
semiannually.

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
10-K (or the  equivalent  thereof  under the  Exchange  Act for foreign  private
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.

<PAGE>


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

     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:

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

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

     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

     on a pro rata  basis and on  substantially  identical  principal  financial

     the payee of any such Indebtedness ceases to be a Restricted  Subsidiary or
     transfers  such  Indebtedness  (other than to the  Company or a  Restricted
     Subsidiary of the Company),  such events shall be deemed,  in each case, to

     Restricted Subsidiary, as the case may be, at the time of such event; and

          (xi)  Indebtedness of the Company and/or any Restricted  Subsidiary in

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:

     Restricted Payment:

          than the sum of (x) the difference  between  Cumulative EBITDA and 1.5
          times Cumulative Interest Expense plus (y) Capital Stock Sale Proceeds
          plus (z) cash received by the Company or a Restricted  Subsidiary from
          a Non-Restricted  Subsidiary  (other than cash which is or is required
          to be repaid or returned to such Non-Restricted Subsidiary); provided,
          however,  that to the extent that any Restricted  Investment  that was
          made after the date of this  Indenture  is sold for cash or  otherwise
          liquidated or repaid for cash,  the amount  credited  pursuant to this
          clause (z) shall be the lesser of (A) the cash  received  with respect
          to such sale,  liquidation or repayment of such Restricted  Investment
          (less the cost of such sale, liquidation or repayment, if any) and (B)
          the  initial  amount of such  Restricted  Investment,  in each case as
          determined in good faith by the Company's Board of Directors.

     (b) The foregoing provisions in Section 4.09(a) shall not prohibit:

          (i) the  payment  of any  dividend  within  60 days  after the date of
     declaration thereof, if at said date of declaration such payment would have
     complied with the provisions of this Indenture;

          (ii) (x) the redemption,  repurchase,  retirement or other acquisition
     of any Equity Interests of the Company or any Restricted  Subsidiary or (y)
     an Investment  in any Person,  in each case, in exchange for, or out of the
     proceeds of, the substantially  concurrent sale (other than to a Restricted
     Subsidiary  of the  Company)  of other  Equity  Interests  (other  than any
     Disqualified  Stock) of the Company,  provided that the Company delivers to
     the Trustee:

               (1) with  respect to any  transaction  involving  in excess of $1
          million,  a  resolution  of the  Board of  Directors  set  forth in an

          a majority of the directors on the Board of Directors; and

          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 (2),  provided  that the amount of such proceeds from
          the sale of such Equity  Interests shall be excluded in each case from
          Capital  Stock Sale  Proceeds  for  purposes of clause  (a)(iv)(2)(y),
          above;

     permitted by this Indenture or the indentures governing the Other Qualified
     Notes or the Applicable Notes or any other instrument  governing  unsecured
     indebtedness  of the  Company  which is pari  passu  with the Notes) on its
     ability to pay dividends or make any other  distributions to the Company or
     any of its Restricted Subsidiaries,  (C) is or will be a Cable Business and
     (D) uses the proceeds of such Investment for  constructing a Cable Business

     (c) Any  Investment in a Subsidiary  (other than the issuance,  transfer or

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:

          (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


                                       38
<PAGE>


     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) with respect to the Notes,  at an offer price in cash in an amount
equal to 100% of the Accreted  Value on the date fixed for closing of such offer
(if such date is prior to April 1, 2003), or 100% of the  outstanding  principal
amount thereof plus accrued and unpaid  interest,  if any, to the date fixed for
the  closing  of such  offer (if such  date is on or after  April 1,  2003),  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.

     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

     determined  by an  investment  banking  firm of  recognized  standing  with
     knowledge  of the  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,


                                       40

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

     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

     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

          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;


                                       41
<PAGE>


               (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

          (ii) this Indenture and the Notes;

          (iii) any agreement covering or relating to Indebtedness  permitted to

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

     of such acquisition (except to the extent such Indebtedness was incurred in
     connection with such


                                       42
<PAGE>


     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;

     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

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  will be  obligated  to pay  Additional  Amounts  with  respect  to such
payment, then such Officers'

<PAGE>


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

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 immediately  preceding the 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

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

by such  consolidation  or into or with which the  Company is merged or to which
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

may be issued or by which there may be secured or evidenced any Indebtedness for
money  borrowed by the Company or any  Restricted  Subsidiary (or the payment of
which is guaranteed by the Company or any Restricted  Subsidiary),  whether such
Indebtedness  or guarantee  now exists or is created  after the  Issuance  Date,
which default:

          (i) is caused by a failure to pay when due principal of or interest on
     such Indebtedness within the grace period provided for in such Indebtedness

     Default"); or

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 Accreted Value of
(if prior to April 1, 2003) or the principal of,  premium,  if any, and interest
on (if on or  after  April  1,  2003),  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............................ 110.750%
             1999............................ 109.675%
             2000............................ 108.600%
             2001............................ 107.525%
             2002............................ 106.450%


                                       47
<PAGE>


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.

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.


                                       48
<PAGE>


     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,  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.


                                       49

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.


                                  ARTICLE VII.
                                     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
and no others and (ii) in the absence of bad faith on its part,  the Trustee may
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
negligent in ascertaining the pertinent facts and (iii) the Trustee shall not be
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.

     (e) The Trustee  may refuse to perform  any duty or  exercise  any right or
power  unless  it  receives  indemnity  satisfactory  to it  against  any  loss,
liability or expense.

     (f) The Trustee  shall not be liable for interest on any money  received by
it except as the Trustee may agree in writing  with the  Company.  Money held in

SECTION 7.02. RIGHTS OF TRUSTEE.

     (a) The Trustee may rely on any  document  believed by it to be genuine and
to have been signed or  presented  by the proper  Person.  The Trustee  need not

     (b) Before the Trustee  acts or  refrains  from  acting,  it may require an
Officers'  Certificate or an Opinion of Counsel,  or both. The Trustee shall not
be liable for any action it takes or omits to take in good faith in  reliance on
such Officers' Certificate or Opinion of Counsel.

     (c) The Trustee may act through agents and shall not be responsible for the
misconduct or negligence of any agent  appointed  with due care.

Material  Subsidiary referred to in clause (ii) of the definition thereof unless
either (1) a Trust  Officer of the  Trustee  assigned to its  Corporate  Trustee
Administration  Department  shall  have  actual  knowledge  thereof,  or (2) the
Trustee shall have  received  notice  thereof in  accordance  with Section 10.02

SECTION 7.03. INDIVIDUAL RIGHTS OF TRUSTEE.

     The Trustee in its individual or any other capacity may become the owner or

with like  rights.  However,  the Trustee is subject to  Sections  7.10 and 7.11
hereof.

SECTION 7.04. TRUSTEE'S DISCLAIMER.

     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
Default or Event of Default in payment on any Note, the Trustee may withhold the

compensation for its services hereunder. The Trustee's compensation shall not be
limited by any law on compensation of a trustee of an express trust. The Company

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.


                                       52
<PAGE>


     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.

     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.

     A successor  Trustee shall deliver a written  acceptance of its appointment
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 7.11. PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY.

     The Trustee is subject to TIA  (Section)  311(a),  excluding  any  creditor

                                  ARTICLE VIII.
                             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
discharged the entire  Obligations  represented by the outstanding  Notes, which
shall thereafter be deemed to be "outstanding"  only for the purposes of Section
8.03 hereof and the other Sections of this Indenture  referred to in clauses (a)
and (b) below, and to have satisfied all its other  obligations under


                                       54
<PAGE>


such Notes 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
solely from the trust fund  described in the  following  paragraph,  payments in
respect of the principal of (or, if applicable,  payments in respect of Accreted
Value),  premium, if any, and interest on such Notes when such payments are due;
(ii) the  Company's  obligations  with  respect to such Notes  under  Article II
hereof; (iii) the rights,  powers,  trusts, duties and immunities of the Trustee
hereunder and the Company's obligations in connection  therewith;  and (iv) this
Article VIII.

          In order to exercise Defeasance:

          (a) the Company must irrevocably  deposit with the Trustee,  in trust,
     for the  benefit  of the  Holders,  pursuant  to an  irrevocable  trust and
     security  agreement in form  satisfactory  to the Trustee,  money in pounds
     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 (or, if  applicable,
     payments in respect of Accreted  Value),  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
     Counsel  (which  counsel  may be an  employee  of the  Company)  reasonably
     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  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;


                                       55
<PAGE>


          (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 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.


                                       56
<PAGE>


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;

     (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


                                       57
<PAGE>


     (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, alter
the manner of  calculating  Accreted Value 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.

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.


                                       58
<PAGE>


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:


                                       60
<PAGE>


     (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

     (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


                                       61
<PAGE>


     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 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,


                                       62
<PAGE>


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.

SECTION 10.09. 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 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

                        [FORM OF REVERSE OF INITIAL NOTE]

                                NTL INCORPORATED



                  10-3/4% Senior Deferred Coupon Note Due 2008

     1. Interest. NTL INCORPORATED,  a Delaware corporation (the "Company"),  is
the  issuer of  10-3/4%  Senior  Deferred  Coupon  Notes  Due 2008 (the  "Senior
Notes").  The Senior Notes are being issued at a discount  from their  principal
amount and will accrete (in  accordance  with the  definition of Accreted  Value
contained in the Indenture) at a rate of 10-3/4%, compounded semiannually, to an
aggregate  principal amount of 300,000,000 Pounds Sterling by April 1, 2003. The
Company  promises to pay  interest on the Senior Notes in cash  semiannually  on
each April 1 and October 1,  commencing on October 1, 2003, to Holders of record
on the immediately preceding March 15 and September 15, respectively at the rate
of 103/4% per annum.  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 April 1, 2003.  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 or
overdue  Accreted  Value at the interest or  accretion  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


                                       5
<PAGE>


Period"), at a rate per annum equal to 0.50% of the Accreted Value of the Senior
Notes (determined  daily). The amount of such additional  interest (the "Special
Interest")  will  increase by an  additional  0.50% of the  Accreted  Value 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 Accreted Value (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,  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 Accreted Value 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


                                       6
<PAGE>


     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 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


                                       7
<PAGE>


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 the Senior Notes include those stated

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
(or the Accreted  Value  thereof at the date of  redemption if prior to April 1,
2003)  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


                                       8
<PAGE>


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  redemption  (or the  Accreted  Value
thereof  at the date  fixed  for  redemption  if prior to April 1,  2003) 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


                                       9
<PAGE>


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  Accreted  Value  thereof on the date of purchase  (if such date is prior to
April 1, 2003), or 101% of the aggregate principal amount thereof,  plus accrued
and unpaid interest to the Purchase Date (if on or after April 1, 2003). 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 Accreted  Value on the date fixed for the
closing  of such  offer (if such date is prior to April 1,  2003) or 100% of the
outstanding  principal amount thereof plus accrued and unpaid interest,  if any,
to the date  fixed for the  closing  of such  offer (if such date is on or after
April 1, 2003).  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


                                       10
<PAGE>


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 or  Accreted  Value 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 or Accreted
Value 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 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.


                                       11
<PAGE>


     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

              10-3/4% Series B Senior Deferred Coupon Note Due 2008

     1. Interest. NTL INCORPORATED,  a Delaware corporation (the "Company"),  is
the  issuer  of  10-3/4%  Series B Senior  Deferred  Coupon  Notes Due 2008 (the
"Senior  Notes").  The Senior  Notes are being  issued at a discount  from their
principal amount and will accrete (in accordance with the definition of Accreted
Value contained in the Indenture) at a rate of 10-3/4%, compounded semiannually,
to an aggregate  principal  amount of  300,000,000  pounds  sterling by April 1,
2003.  The  Company  promises  to pay  interest  on the  Senior  Notes  in  cash
semiannually  on each April 1 and October 1,  commencing  on October 1, 2003, to
Holders  of record  on the  immediately  preceding  March 15 and  September  15,
respectively,  at the rate of 10-3/4% per annum.  Interest  on the Senior  Notes
will accrue from the most  recent  date to which  interest  has been paid on the
Company's  10-3/4% Senior Notes Due 2008, or if no interest has been paid,  from
April 1,  2003.  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, or overdue  Accreted  Value at the interest or accretion  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,


                                       4

     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
     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


                                       5
<PAGE>


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 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  300,000,000  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 ........................... 105.375%
             2004............................ 103.583%
             2005............................ 101.792%
             2006 and thereafter............. 100.000%


                                       6
<PAGE>


     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
(or the Accreted  Value  thereof at the date of  redemption if prior to April 1,
2003)  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  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 to the date fixed for  redemption  interest  (or the  Accreted  Value
thereof  at the date  fixed  for  redemption  if prior to April 1,  2003) 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.


                                       7

     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 purchase price equal to 101% of
the  Accreted  Value  thereof on the date of purchase  (if such date is prior to
April 1, 2003), or 101% of the aggregate principal amount thereof,  plus accrued
and unpaid interest to the Purchase Date (if on or after April 1, 2003). 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 Accreted  Value on the date fixed for the
closing  of such  offer (if such date is prior to April 1,  2003) or 100% of the
outstanding  principal amount thereof plus accrued and unpaid interest,  if any,
to the date  fixed for the  closing  of such  offer (if such date is on or after
April 1, 2003).  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


                                       8
<PAGE>


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 Trustee may declare all the Senior Notes or Accreted Value 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 or Accreted  Value 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


                                       9
<PAGE>


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.

     21.  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:
