     This summary highlights information about us and the exchange offer which
is contained elsewhere or incorporated by reference in this prospectus. This
summary may not contain all the information that is important to you. You should
read the entire prospectus, including the financial statements and related
notes, before making a decision to exchange your old notes. When we refer to NTL
in this prospectus, we mean NTL Communications Corp. and its consolidated
subsidiaries, except where we make it clear that we are only referring to NTL
Communications Corp. The statistical data included in this prospectus is as at
December 31, 1998, unless we indicate otherwise. That statistical data does not
include statistical data relating to ComTel, Partners or Diamond, each of which
we have recently acquired.
    
 
                                   ABOUT NTL
 
     We are a leading communications company in the United Kingdom, providing
residential, business and wholesale customers with the following services:
 
   
     - residential telecoms and television services, including residential
       telephony, cable television and Internet access services;
    
 
   
     - national telecoms services including national business telecoms, national
       and international carrier telecommunications, Internet services and
       satellite and radio communications services; and
    
 
     - broadcast services including digital and analog television and radio
       broadcast transmission services.
 
     We provide a broad range of services over local, national and international
network infrastructure. We operate:
 
     - advanced local broadband networks serving entire communities throughout
       our regional franchise areas;
 
   
     - the UK's first backbone telecommunications network using an advanced
       network transmission standard known as synchronous digital hierarchy
       technology,
    
 
   
     - satellite earth stations and radio communications facilities from our
       tower sites across the UK; and
    
 
     - a broadcast transmission network which provides national, regional and
       local analog and digital transmission services to customers throughout
       the UK.
 
   
     Our objective is to exploit the convergence of the telecommunications,
entertainment and information services industries to become a premier new era
communications company in the UK, which will offer these services to
residential, business and wholesale customers on a national scale. We believe
that we will be able to deliver our strategy, based on our entrepreneurial
approach, innovative marketing and technical excellence.
    
 
   
     We are a Delaware corporation, and were incorporated on April 2, 1993. In
March 1997, we changed our name from International CableTel Incorporated to NTL
Incorporated to reflect the integration of the services we provide following our
acquisition
    
                                        1
<PAGE>   5
 
   
of NTL Group Limited in 1996, and to capitalize on NTL Group Limited's 40-year
history in the UK as a provider of reliable communications services.
    
 
   
     On April 1, 1999, we completed a corporate restructuring to create a
holding company structure. The holding company restructuring was accomplished
through a merger so that all of our stockholders at the effective time of the
merger became stockholders of NTL Incorporated, the new holding company, and we
became a subsidiary of the new holding company and changed our name to NTL
Communications Corp.
    
 
   
                              RECENT DEVELOPMENTS
    
 
   
     On March 19, 1999, the Commonwealth of Australia announced that NTL
Incorporated was the successful bidder to acquire and operate the Australian
National Transmission Network at a purchase price of approximately $407.0
million. This acquisition is expected to close in late April or early May 1999.
While NTL Incorporated ultimately intends to finance the purchase price by a
separate financing at either the NTL Incorporated level or at the level of one
of NTL Incorporated's subsidiaries, the funds necessary to pay the purchase
price for the Australian network may be obtained, subject to applicable legal
and contractual restrictions, from a dividend or other distributions by us to
NTL Incorporated.
    
 
   
     On April 1, 1999, Diamond Cable Communications Plc, a subsidiary of ours,
commenced required offers to the holders of all of the outstanding Diamond and
Diamond subsidiary notes at a price equal to 101% of their accreted value or
principal amount, as applicable. Those offers had an aggregate value of
approximately $1.4 billion (L842 million). Those offers were made as a result of
the "change of control" provisions of the indentures pursuant to which these
notes were issued. The offers will expire on April 30, 1999. As of April 6,
1999, all of these Diamond notes were trading at prices above their redemption
prices.
    
 
   
     If those trading patterns prevail, Diamond would not expect the holders of
the notes to exercise the right to redeem. If the trading prices of the Diamond
notes declined to levels below 101% of their accreted value or principal amount,
as the case may be, redemptions would be more likely to occur. We have entered
into a bridge facility to finance the redemption of Diamond notes tendered, if
any, which is subject to various funding conditions. In addition, the 13 1/4%
Diamond notes are redeemable at the option of Diamond on September 30, 1999 at
107.125% of the principal amount at maturity.

           CONSEQUENCES OF EXCHANGING OLD NOTES IN THE EXCHANGE OFFER
 
   
     The following summary is based on interpretations by the staff of the SEC
in no action letters issued to third parties. Unless you are an affiliate of
NTL, generally if you exchange your old notes for new notes in the exchange
offer you may offer those new notes for resale, resell those new notes, and
otherwise transfer those new notes without compliance with the registration and
prospectus delivery provisions of the Securities Act. However new notes must be
acquired in the ordinary course of your business. In addition, unless you are a
broker-dealer, you must not engage in, intend to engage in or have any
arrangement or understanding with any person to participate in, a distribution
of new notes.
    
 
   
     If you do not exchange your old notes for new notes in the exchange offer,
your old notes will continue to be subject to provisions of the indenture under
which they were issued regarding transfer and exchange of the old notes and the
restrictions on transfer contained in the legend on the old notes. See "Risk
Factors -- If you do not exchange your old notes for new notes you will continue
to hold notes subject to restrictions on transfer," "The exchange offer" and
"Registration rights."
    
 
                      SUMMARY DESCRIPTION OF THE NEW NOTES
 
   
     The terms of the new notes and the old notes are identical in all material
respects, except for:
    
 
   
     (1) the transfer restrictions and registration rights relating to the old
         notes, and
    
 
   
     (2) some provisions under the registration rights agreements providing for
         special interest on the old notes under some circumstances relating to
         timing of the exchange offer, which will terminate on completion of the
         exchange offer.

                             2003. From October 1, 2003, interest on the 12 3/8%
                             new notes will accrue at the rate of 12 3/8% per
                             annum and will be payable in cash, semi-annually in
                             arrears, on April 1 and October 1, commencing on
                             April 1, 2004.
    
 
   
Optional redemption........  On or after October 1, 2003, the new notes will be
                             redeemable at our option, in whole at any time or
                             in part on one or more occasions, at the redemption
                             prices set forth in this prospectus, plus accrued
                             and unpaid interest, if any, to the date of
                             redemption.
    
 
   
Ranking....................  The new notes will rank senior in right of payment
                             to all of our subordinated indebtedness and will
                             rank equal in right of payment with all of our
                             existing and future unsubordinated obligations. As
                             of December 31, 1998, we had approximately $3.7
                             billion of unsubordinated debt outstanding. The new
                             notes will be effectively subordinated to all
                             existing and future indebtedness and other
                             liabilities of our subsidiaries with respect to the
                             cash flow and assets of those subsidiaries. The new
                             notes will rank senior to all our 7% convertible
                             subordinated notes due 2008.
    
 
   
Change of control..........  If a change of control triggering event occurs we
                             will be required to make an offer to purchase all
                             of the notes at 101% of their principal amount plus
                             accrued and unpaid interest to the date of
                             purchase. In the case of repurchases of 12 3/8%
                             notes before October 1, 2003, the purchase price
                             will be equal to 101% of the accreted value at the
                             date of repurchase.
    
 
   
                             We may not have sufficient funds or the financial
                             resources necessary to satisfy our obligations to
                             repurchase the 11 1/2% notes and other debt that
                             may become repayable upon a change of control
                             triggering event.
    
 
   
Certain Covenants..........  The indentures governing the notes contains
                             covenants relating to, among other things, the
                             following matters:
    
 
                             - restricted payments;
 
                             - incurrence of additional indebtedness and
                               issuance of preferred stock;
 
                             - liens;
 
                             - dividend and other payment restrictions affecting
                               subsidiaries;
 
                             - mergers, consolidations and sales of assets;

                                  RISK FACTORS
    
 
   
     You should consider carefully all of the information in this prospectus and
incorporated by reference in this prospectus. See "Where you can find more
information about us." In particular, you should carefully evaluate the
following risks before tendering your old notes in the exchange offer. However,
the risk factors set forth below, other than the first risk factor, are also
generally applicable to the old notes as well as the new notes.
    
 
   
IF YOU DO NOT EXCHANGE YOUR OLD NOTES FOR NEW NOTES YOU WILL CONTINUE TO HOLD
NOTES SUBJECT TO RESTRICTIONS ON TRANSFER AND WHICH ARE NOT FREELY TRADEABLE
    
 
   
     If you do not tender your old notes or you tender your old notes and we do
not accept the tender, your old notes will continue to be subject to their
existing restrictions on transfer and exchange. In general, old notes, unless
registered under the Securities Act, may not be offered or sold except pursuant
to an exemption from, or in a transaction not subject to, the Securities Act and
applicable state securities laws. Except in limited circumstances which we
summarize under "Registration rights" in this prospectus, we will have no
obligation to register your old notes under the Securities Act. We do not expect
that we will take any action to register the old notes under the Securities Act
unless we are required to do so in those limited circumstances.
    
 
   
OUR SUBSTANTIAL LEVERAGE COULD ADVERSELY AFFECT OUR FINANCIAL HEALTH AND PREVENT
US FROM FULFILLING OUR OBLIGATION UNDER THE NOTES
    
 
     We are and, for the foreseeable future will continue to be, highly
leveraged.
 
   
     On December 31, 1998, our total long-term indebtedness, including our 13%
senior redeemable exchangeable preferred stock, was approximately $5.2 billion.
    
 
   
     The degree to which we are leveraged could have important consequences to
you including the following:
    
 
   
     - increasing our vulnerability to adverse changes in general economic
       conditions or increases in prevailing interest rates,
    
 
   
     - limiting our ability to obtain additional financing for working capital,
       capital expenditures, acquisitions and general corporate purposes,
       including the build out of the networks in the franchises and the
       development and expansion of our business,
    
 
   
     - requiring a substantial portion of our cash flow from operations to be
       dedicated to debt service requirements, which reduces the funds available
       for dividends, operations and future business opportunities and
    
 
   
     - increasing our exposure to increases in interest rates given that some of
       our borrowings may be at variable rates of interest.
    
 
   
     In addition, we may under some circumstances be obligated to offer to
repurchase outstanding securities, including the notes, before maturity. We
cannot assure you that we will have available financial resources necessary or
that we will otherwise be able to
    
 
                                        7
<PAGE>   11
 
   
repurchase those securities in those circumstances, including, without
limitation, if a change of control triggering event occurs under those
securities and/or the notes.
    
 
   
     The indentures governing our existing indebtedness allow us to assume
additional debt in order to finance our working capital and capital expenditure
requirements, finance the construction of our network and finance the
acquisition of either tangible or intangible assets, licenses and computer
software that are used in connection with a cable business, as well as entities
that are directly or indirectly engaged in a cable business.
    
 
   
THE ANTICIPATED CONSTRUCTION COSTS OF OUR NETWORK WILL INCREASE AS A RESULT OF
OUR RECENT ACQUISITIONS AND WILL REQUIRE SUBSTANTIAL AMOUNTS OF ADDITIONAL
FUNDING
    
 
   
     Following our recent acquisitions, our capital expenses and cost of
operations for the development, construction and operation of our combined
telecommunications networks will significantly increase. We estimate that
significant amounts of additional funding will be necessary to meet these
capital expenditure requirements.
    
 
     We cannot be certain that:
 
     - we will be able to obtain additional financing with acceptable terms,
 
     - actual construction costs will meet our expectations,
 
     - we will satisfy conditions precedent to advances under future credit
       facilities,
 
     - we will not acquire additional businesses that require additional
       capital,
 
     - we will be able to generate sufficient cash from operations to meet
       capital requirements, debt service and other obligations when required or
 
     - our subsidiaries will withstand exposure to exchange and interest rate
       fluctuations.
 
     We do not have any firm additional financing plans to address the factors
enumerated above, except in relation to our new credit facility which we discuss
below.
 
   
NEED FOR ADDITIONAL FINANCING -- WE DO NOT EXPECT TO GENERATE SUFFICIENT CASH
FLOW TO REPAY AT MATURITY ALL OF OUR OUTSTANDING INDEBTEDNESS
    
 
   
     We anticipate that we will not generate sufficient cash flow from
operations to repay at maturity all of our outstanding indebtedness. Some of the
measures we may take to refinance our debt include:
    
 
   
     - refinancing all or portions of that indebtedness,
    
 
   
     - seeking modifications to the terms of that indebtedness,
    
 
     - seeking additional debt financing, which may require us to obtain the
       consent of some of our lenders, and
 
     - seeking additional equity financing.
 
     We cannot be certain that we will succeed in executing any of these
measures.
 
                                        8
<PAGE>   12
 
   
WE CANNOT BE CERTAIN THAT WE WILL BE SUCCESSFUL IN INTEGRATING ACQUIRED
BUSINESSES INTO OURS, OR THAT WE WILL REALIZE THE BENEFITS WE ANTICIPATE FROM
ANY ACQUISITION
    
 
   
     We will continue to consider strategic acquisitions and combinations that
involve operators or owners of licenses to operate cable, telephone, television
or telecommunications systems or services and related businesses that operate
principally in the UK. If consummated, some of these transactions would
significantly alter our holdings and might require us to incur substantial
indebtedness or raise additional equity. We cannot assure you that, with respect
to the recent acquisitions of Comcast, ComTel, Eastern and Diamond, as well as
future acquisitions, that we:
    
 
     - will realize any anticipated benefits,
 
     - will successfully integrate the businesses with our operations, or
 
   
     - will manage such integration without adversely affecting us.
    
 
   
WE ARE A HOLDING COMPANY THAT IS DEPENDENT UPON CASH FLOW FROM OUR
SUBSIDIARIES -- OUR ABILITY TO ACCESS THAT CASH FLOW MAY BE LIMITED IN SOME
CIRCUMSTANCES
    
 
   
     We are a holding company and conduct our operations through direct and
indirect wholly-owned subsidiaries and affiliated joint ventures. Consequently,
we hold no significant assets other than our investments in and advances to our
subsidiaries and affiliated joint ventures. We depend upon the receipt of
sufficient funds from our subsidiaries and affiliated joint ventures to meet our
obligations. The terms of existing and future indebtedness of our subsidiaries
may limit the payment of dividends, loans and other distributions to us.
    
 
   
     Additionally, following the liquidation of a subsidiary or joint venture,
the creditors of that subsidiary or joint venture will be entitled to be paid in
full before we are entitled to a distribution of any assets in the liquidation.
The claims of the lenders under our credit facility also rank ahead of any
obligations of our subsidiaries to us.
    
 
   
     The old notes are, and the new notes will effectively rank behind all
existing and future indebtedness and other liabilities and commitments of our
subsidiaries, including borrowings under the new credit facility. On December
31, 1998, after giving pro forma effect to the Diamond acquisition, the total
liabilities of our subsidiaries were approximately $2.5 billion.
    
 
WE HAVE HISTORICALLY INCURRED LOSSES AND GENERATED NEGATIVE CASH FLOWS
 
   
     We cannot be certain that we will achieve or sustain profitability in the
future. Failure to achieve profitability could diminish our ability to sustain
our operations and obtain additional required funds. In addition, a failure to
achieve or sustain profitability would adversely affect our ability to make
required payments on our indebtedness and our preferred stock.
    
 
   
     We had net losses for the years ended December 31,
    
 
   
     - 1998: $534.6 million
    
 
     - 1997: $333.1 million
 
                                        9
<PAGE>   13
 
     - 1996: $254.5 million
 
     - 1995: $90.8 million
 
     - 1994: $29.6 million
 
     - 1993: $11.1 million
 
   
     As of December 31, 1998, our accumulated deficit was $1.3 billion.
    
 
   
     Construction and operating expenditures have resulted in negative cash
flow, which we expect will continue at least until we establish an adequate
customer base. We also expect to incur substantial additional losses.
    
 
WE HAVE HISTORICALLY HAD A DEFICIENCY OF EARNINGS TO FIXED CHARGES AND EARNINGS
TO COMBINED FIXED CHARGES AND PREFERRED STOCK DIVIDENDS
 
   
     For the years ended December 31, 1998, 1997, 1996, 1995 and 1994, our
earnings were insufficient to cover fixed charges by approximately $565.7
million, $355.4 million, $257.1 million, $105.4 million and $31.8 million,
respectively. Our earnings for the year ended December 31, 1998 and 1997 were
insufficient to cover combined fixed charges and preferred stock dividends by
approximately $584.5 million and $367.4 million, respectively. Fixed charges
consist of interest expense, including capitalized interest, amortization of
fees related to debt financing and rent expense deemed to be interest.
    
 
   
WE MAY UTILIZE SOME OF OUR EXISTING FINANCIAL RESOURCES TO REDEEM DIAMOND NOTES
    
 
   
     If holders of the Diamond and Diamond subsidiary notes tender their notes
in the current repurchase offer, we will be required to use our available
financial resources or additional borrowings to fund such redemption. A maximum
of approximately $1.4 billion will be required for this purpose.
    
 
   
WE MAY DISTRIBUTE OR DIVIDEND FUNDS TO NTL INC.
    
 
   
     Under our existing indentures, we are permitted, and under the indenture
for these notes will be permitted, to dividend or distribute certain amounts to
NTL Inc., our parent. A distribution may occur in the near future to finance all
or a portion of NTL Inc.'s purchase of the Australian National Transmission
Network for approximately $407.0 million. If those funds are distributed, NTL
Inc. may, but is not required to, recontribute them to us as and if it obtains
alternative financing for the purchase price. Such dividends and distributions,
to the extent permitted, may be made at other times for other purposes.
    
 
   
WE ARE SUBJECT TO SIGNIFICANT COMPETITION, WHICH WE EXPECT TO INTENSIFY, IN EACH
OF OUR BUSINESS AREAS -- IF WE ARE UNABLE TO COMPETE SUCCESSFULLY OUR FINANCIAL
CONDITION AND RESULTS OF OPERATIONS COULD BE ADVERSELY AFFECTED
    
 
   
     We face significant competition from established and new competitors in the
areas of residential telephony, business telecoms services and cable television.
We believe that competition will intensify in each of these business areas,
particularly business telecommunications and the Internet. If we are unable to
compete successfully our financial condition and results of operations could be
adversely affected.
    
 
                                       10
<PAGE>   14
 
   
     Residential Telephony.   We compete primarily with British
Telecommunications plc in providing telephone services to residential customers.
British Telecommunications, formerly the only major national public telephone
operator in the UK, occupies an established market position and manages fully
built networks with resources that are substantially greater than ours. Our
growth in telecommunications services depends upon our ability to appropriate
British Telecommunications' customers.
    
 
   
     We also compete with mobile networks, which is a technology that may grow
to be competitive with our other networks, particularly if call charges are
reduced further on the mobile networks. We cannot assure you that we will be
able to compete successfully with British Telecommunications or any other
telecommunication operations.
    
 
   
     Business Telecommunications.   Competition in the business
telecommunications services sector is based on price range and quality of
services. We expect price competition to intensify if existing and new market
entrants compete aggressively. British Telecommunications is also our principal
competitor in providing business telecommunications services. Additionally, we
compete with Cable & Wireless Communications, Energis Communications Limited,
Scottish Telecom in Scotland and with other companies that have been granted
telecommunications licenses such as MCI-WorldCom and Colt.
    
 
   
     Cable television.   Our cable television systems compete with a wide range
of communications and entertainment services. Our cable television systems
compete with direct reception over-the-air broadcast television, direct-to-home
satellite services and satellite master antenna systems. Additionally, pay
television and pay-per-view services offered by us compete with other
communications and entertainment media, including home video, cinema exhibition
of feature films, live theater and newly emerging multimedia services.
    
 
   
     Legislation in the UK provides for the introduction of digital terrestrial
television that will initially provide an additional 18 or more new terrestrial
channels serving between 60% and 90% of the UK's population. The introduction of
digital terrestrial television, as well as digital satellite television, will
provide increased competition for our cable television systems.
    
 
   
     Broadcast Services.   In February 1997, the UK Government sold the Home
Service and World Service transmission businesses of the British Broadcasting
Corporation to a consortium led by Castle Tower Corporation. We may encounter
significant competition from this consortium for a range of transmission
services, for example, from local radio stations.
    
 
   
OUR PRINCIPAL BUSINESSES ARE SUBJECT TO EXTENSIVE GOVERNMENT REGULATION,
INCLUDING PRICING REGULATION, WHICH MAY CHANGE ADVERSELY TO US
    
 
   
     Our principal business activities in the UK are regulated and supervised by
various governmental bodies that include the Independent Television Commission,
the Department of Culture, Media and Sport, the Radio Communications Agency, the
Radio Authority and the Office of Telecommunications under the directions of the
Director
    
 
                                       11
<PAGE>   15
 
   
General and the Department of Trade and Industry on behalf of The Secretary of
State for Trade and Industry. Changes in laws, regulations or governmental
policy or the interpretations of such laws or regulations affecting our
activities and those of our competitors, such as licensing requirements, changes
in price regulation and deregulation of interconnection arrangements, could have
a material adverse effect on us.
    
 
   
     In particular, the prices that we may charge the ITV companies, Channel 4
and Welsh Fourth Channel, for television transmission services are subject to
price controls imposed by the OFTEL. These price controls may be reviewed again
prior to 2002 and price controls for the year following December 31, 2002 may
have a material adverse effect on the revenues receivable from the ITV
companies, Channel 4 and Welsh Fourth Channel.
    
 
     As a UK company we are subject to regulatory initiatives of the European
Commission. Changes in EU Directives, particularly television "production" and
"programming" quotas, may reduce the range of programing and increase the costs
of purchasing television programming. In addition, EU Directives may introduce
provisions that require us to provide access to our cable network infrastructure
to other service providers.
 
   
OUR BROADCAST SERVICES BUSINESS IS DEPENDENT UPON SITE SHARING ARRANGEMENTS WITH
OUR PRINCIPAL COMPETITOR
    
 
   
     As a result of, among other factors, a natural shortage of potential
transmission sites and the difficulties in obtaining planning permission for
erection of further masts, the Castle Tower Corporation Consortium and NTL have
made arrangements to share a large number of sites. We cannot assure you that
the site sharing agreement or the site licenses will not be terminated.
Termination of the site sharing arrangements would have a material adverse
effect on us.
    
 
   
     Under the present arrangements, one of the parties is the owner, lessor or
licensor of each site and the other party is entitled to request a license to
use specified facilities at that site. Each site license granted pursuant to the
site sharing agreement is for an initial period expiring on December 31, 2005,
subject to title and to the continuation in force of the site sharing agreement.
Each site sharing agreement provides that, if requested by the sharing party, it
will be extended for further periods. Either party may terminate the agreement
by 5 years' notice in writing to the other expiring on December 31, 2005 or at
any date which is a date 10 years or a multiple of 10 years after December 31,
2005.
    
 
   
FAILURE TO MANAGE OUR GROWTH AND EXPANSION COULD HAVE A MATERIAL ADVERSE EFFECT
ON US
    
 
   
     We have experienced rapid growth and development in a relatively short
period, and we plan to meet our strategic objectives and regulatory milestones.
Management of that growth will require, among other things:
    
 
   
     - stringent control of construction and other costs,
    
 
   
     - continued development of our financial and management controls,
    
 
   
     - increased marketing activities, and
    
                                       12
<PAGE>   16
 
   
     - the training of new personnel.
    
 
     Failure to manage our rapid growth and development successfully could have
a material adverse effect on us.
 
WE ARE DEPENDENT UPON A SMALL NUMBER OF KEY PERSONNEL
 
   
     A small number of key executive officers manage our businesses, and the
loss of one or more of them could have a material adverse effect on us. We
believe that our future success will depend in large part on our continued
ability to attract and retain highly skilled and qualified personnel. We have
not entered into written employment contracts or non-compete agreements with,
nor have we obtained life insurance policies covering, those key executive
officers. Some of our senior managers also serve as members of senior management
of other companies in the telecommunications business.
    
 
THE TELECOMMUNICATIONS INDUSTRY IS SUBJECT TO RAPID TECHNOLOGICAL CHANGES AND WE
CANNOT PREDICT THE EFFECT OF SUCH CHANGES ON OUR BUSINESSES
 
     The telecommunications industry is subject to rapid and significant changes
in technology and the effect of technological changes on our businesses cannot
be predicted. However, the cost of implementation for emerging and future
technologies could be significant, and our ability to fund such implementation
may depend on our ability to obtain additional financing.
 
WE ARE SUBJECT TO CURRENCY RISK TO THE EXTENT WE OBTAIN FINANCING IN US DOLLARS
BUT INCUR EXPENSES IN POUNDS STERLING
 
   
     To the extent that we obtain financing in United States dollars and incur
construction and operating expenses in British pounds sterling, we will
encounter currency exchange rate risks. In addition, we generate revenues
primarily in British pounds sterling while we pay interest and principal
obligations with respect to most of our existing indebtedness in United States
dollars. We cannot assure you that this hedging transaction or any other hedging
transaction we might enter into will be successful and that shifts in the
currency exchange rates will not have a material adverse effect on us.
    
 
WE HAVE LIMITED INSURANCE COVERAGE OF OUR NETWORK
 
     We obtain insurance of the type and in the amounts that we believe are
customary in the UK for similar companies. Consistent with this practice, we do
not insure the underground portion of our cable network. Any catastrophe that
affects a significant portion of a system's underground cable network could
result in substantial uninsured losses.

                               THE EXCHANGE OFFER
    
 
   
TERMS OF THE EXCHANGE OFFER; PERIOD FOR TENDERING OLD NOTES
    
 
   
     This prospectus and the accompanying letter of transmittal set out the
terms and conditions of the exchange offer. On and subject to those terms and
conditions we will accept for exchange old notes which are properly tendered on
or before the expiration date and not withdrawn as permitted below. The
expiration date is 5:00 p.m., New York City time, on                , 1999.
However, if we, in our sole discretion, extend the period of time for which the
exchange offer is open, the expiration date will be the latest time and date to
which we extend the exchange offer.
    
 
   
     This prospectus, together with the letter of transmittal, is first being
sent on or about the date of this prospectus, to all holders of old notes known
to us. Our obligation to accept old notes for exchange under the exchange offer
is subject to the conditions described under "Conditions to the exchange offer"
below.
    
 
   
     We expressly reserve the right, at any time or on one or more occasions, to
extend the period of time during which the exchange offer is open, and delay
acceptance for exchange of any old notes, by giving oral or written notice of
the extension to you. During any extension of the exchange offer, all old notes
previously tendered will remain subject to the exchange offer and may be
accepted for exchange by us. If we do not accept any old notes tendered for
exchange for any reason they will be returned to you. We will return those notes
without expense to you as promptly as practicable after the end of the exchange
offer.
    
 
   
     Old notes tendered in the exchange offer must be in denominations of
principal amount of $1,000 and any whole multiple of $1,000.
    
 
   
     We expressly reserve the right to amend or terminate the exchange offer,
and not to accept for exchange any old notes which we have not already accepted
for exchange, if any of the conditions of the exchange offer specified below
under "Conditions to the exchange offer" occur. We will give oral or written
notice of any extension, amendment, non-acceptance or termination to you as
promptly as practicable. A notice in the case of any extension will be issued by
means of a press release or other public announcement no later than 9:00 a.m.,
New York City time, on the next business day after the previously scheduled
expiration date.
    
 
   
     The tender to us of old notes by you and the acceptance of your tender by
us will be a binding agreement between us on the terms and subject to the
conditions set forth in this prospectus and in the accompanying letter of
transmittal in respect of the old notes tendered by you.
    
 
   
PROCEDURES FOR TENDERING OLD NOTES
    
 
   
     When we refer to a holder of old notes in this section of the prospectus
relating to the exchange offer, we include any participant in the DTC system
whose name appears on a security position listing as the holder of those old
notes. Any holder who wishes to tender old notes for exchange in the exchange
offer must transmit the letter of
    
 
                                       16
<PAGE>   20
 
   
transmittal, properly completed and duly executed, including all other documents
required by the letter of transmittal or, in the case of a book-entry transfer,
an agent's message instead of a letter of transmittal to The Chase Manhattan
Bank as exchange agent at one of the addresses set forth below under "Exchange
agent", on or before the expiration date.
    
 
     In addition, either
 
   
     - certificates for the tendered old notes must be received by the exchange
       agent along with the letter of transmittal before the expiration date,
    
 
   
     - a timely confirmation of a book-entry transfer of the tendered old notes,
       which we refer to as a book-entry confirmation, into the appropriate
       exchange agent's account at DTC pursuant to the procedure for book-entry
       transfer described below, must be received by the exchange agent before
       the expiration date along with the letter of transmittal or an agent's
       message instead of a letter of transmittal, or
    
 
   
     - the holder must comply with the guaranteed delivery procedures we
       describe below.
    
 
   
     An agent's message means a message, transmitted by DTC to and received by
the exchange agent. An agent's message forms a part of a book-entry
confirmation, which states that DTC has received an express acknowledgment from
the tendering participant stating that the participant has received and agrees
to be bound by, and make the representations and warranties contained in, the
appropriate letter of transmittal and that we may enforce such letter of
transmittal against the participant.
    
 
     The method of delivery of old notes, letters of transmittal and all other
required documents is at your election and risk. If delivery is by mail, we
recommend that you use registered mail, properly insured, with return receipt
requested. In all cases, you should allow sufficient time to assure delivery
before the expiration date. No letters of transmittal or old notes should be
sent to NTL.
 
     Signatures on a letter of transmittal or a notice of withdrawal, as the
case may be, must be guaranteed unless
 
     - you have not completed the box entitled "Special Issuance Instructions"
       or "Special Delivery Instructions" on the letter of transmittal or
 
   
     - the old notes are tendered for the account of an eligible institution, as
       we define that term below.
    
 
   
     In the event that a signature on a letter of transmittal or a notice of
withdrawal is required to be guaranteed, the guarantee must be by a firm which
is
    
 
   
     - a member of a registered national securities exchange
    
 
   
     - a member of the National Association of Securities Dealers, Inc.
    
 
                                       17
<PAGE>   21
 
   
     - by a commercial bank or trust company having an office or correspondent
       in the United States or
    
 
   
     - by such other Eligible Institution within the meaning of Rule 17(A)(d)-15
       of the Exchange Act.
    
 
   
We refer to each of the institutions in the bullet points above as eligible
institutions. If old notes are registered in the name of a person other than a
signer of the letter of transmittal, the old notes surrendered for exchange must
be endorsed by, or be accompanied by a written instrument or instruments of
transfer, or exchange, in satisfactory form as determined by us in our sole
discretion, duly executed by the registered holder with the signature on those
documents guaranteed by an eligible institution.
    
 
     All questions as to the validity, form, eligibility, including time of
receipt, and acceptance of old notes tendered for exchange will be determined by
us in our sole discretion. Our determination shall be final and binding. We
reserve the absolute right to reject any and all tenders of any particular old
note not properly tendered or to not accept any particular old note which
acceptance might, in our judgment or the judgment of our counsel, be unlawful.
We also reserve the absolute right to waive any defects or irregularities or
conditions of the exchange offer as to any particular old note either before or
after the expiration date, including the right to waive the ineligibility of any
holder who seeks to tender old notes in the exchange offer.
 
   
     The interpretation by us of the terms and conditions of the exchange offer
as to any particular old note either before or after the expiration date,
including the appropriate letter of transmittal and the instructions to the
letter of transmittal shall be final and binding on all parties. Any defects or
irregularities in connection with tenders of old notes for exchange must be
cured within reasonable period of time determined by us unless we waive those
defects or irregularities. Neither we, the exchange agent nor any other person
shall be under any duty to give you notification of any defect or irregularity
with respect to any tender of old notes by you for exchange, nor shall any of
them incur any liability for failure to give such notification.
    
 
   
     If a letter of transmittal is signed by a person or persons other than the
registered holder or holders of old notes, the old notes must be endorsed or
accompanied by appropriate powers of attorney. The old notes or the power of
attorney should be signed exactly as the name or names of the registered holder
or holders that appear on the old notes.
    
 
   
     If a letter of transmittal, any old notes or powers of attorney are signed
by trustees, executors, administrators, guardians, attorneys-in-fact, officers
of corporations or others acting in a fiduciary or representative capacity, the
person signing should so indicate when signing and, in addition, proper evidence
satisfactory to us of their authority to so act must be submitted with the
letter of transmittal, unless we waive it.
    
 
                                       18
<PAGE>   22
 
   
     By tendering, you will represent to us that, among other things,
    
 
   
     - the new notes acquired in the exchange offer are being obtained in the
       ordinary course of business of the person receiving the new notes,
       whether or not that person is the holder,
    
 
   
     - that neither the holder nor any other person receiving the new notes has
       an arrangement or understanding with any person to participate in the
       distribution of the notes and
    
 
   
     - that neither the holder nor any other person receiving the new notes is
       an affiliate, as defined under Rule 405 of the Securities Act, of NTL.
    
 
     If you are an affiliate of NTL, are engaged in or intend to engage in or
have any arrangement with any person to participate in the distribution of the
new notes to be acquired pursuant to the exchange offer, you
 
   
     - cannot rely on the applicable interpretations of the staff of the SEC and
    
 
   
     - must comply with the registration and prospectus delivery requirements of
       the Securities Act in connection with any resale transaction.
    
 
   
     If you are a broker-dealer who holds old notes acquired for your own
account as a result of market-making activities or other trading activities, and
you receive new notes in exchange for those old notes in the exchange offer, you
may be an "underwriter" within the meaning of the Securities Act and must
acknowledge that you will deliver a prospectus meeting the requirements of the
Securities Act in connection with any resale of the new notes. The letter of
transmittal states that by so acknowledging and by delivering a prospectus, you
will not be deemed to admit that you are an "underwriter" within the meaning of
the Securities Act.
    
 
ACCEPTANCE OF OLD NOTES FOR EXCHANGE; DELIVERY OF NEW NOTES
 
     Upon satisfaction or waiver of all of the conditions to the exchange offer,
we will
 
     - accept, promptly after the expiration date, all old notes properly
tendered,
 
     - issue the new notes promptly after acceptance of the old notes and
 
     - cause the new notes to be authenticated by the trustee.
 
   
     For purposes of the exchange offer, we shall be deemed to have accepted
properly tendered old notes for exchange when, as and if we have given oral,
promptly confirmed in writing, or written notice of that acceptance to the
exchange agent. For each old note accepted for exchange, the holder of such old
note will receive a new note of the same class having a principal amount at
maturity equal to that of the surrendered old note.
    
 
   
     The 11 1/2% new notes will bear interest from the most recent date to which
interest has been paid on the 11 1/2% old notes. Accordingly, if the relevant
record date for interest payment occurs after the completion of the exchange
offer, registered holders of 11 1/2% new notes on that record date will receive
interest accruing from the most recent date to which interest has been paid. If,
however, the relevant record date for interest
    
 
                                       19
<PAGE>   23
 
   
payment occurs prior to the completion of the exchange offer, registered holders
of 11 1/2% old notes on such record date will receive interest accruing from the
most recent date to which interest has been paid. 11 1/2% old notes accepted for
exchange will cease to accrue interest from and after the date of completion of
the exchange offer, except as set forth in the immediately preceding sentence.
If you tender 11 1/2% old notes and they are accepted for exchange, you will not
receive any payment in respect of interest, if any, on those 11 1/2% old notes
otherwise payable on any interest payment date the record date for which occurs
on or after completion of the exchange offer.
    
 
   
     If any old notes tendered by you are not accepted for any reason set forth
in the terms and conditions of the exchange offer or if you submitted old notes
for an amount or quantity greater than you desire to exchange, those unaccepted
or non-exchanged old notes will be returned without expense to you. In the case
of old notes tendered by book-entry transfer into the exchange agent's account
at DTC pursuant to the book-entry procedures described below, those
non-exchanged old notes will be credited to an account maintained with DTC as
promptly as practicable after the end of the exchange offer.
    
 
BOOK-ENTRY TRANSFER
 
   
     The exchange agent will request the establishment of accounts with respect
to the old notes at DTC for purposes of the exchange offer within two business
days after the date of this prospectus unless the exchange agent already has
established an account with DTC suitable for the exchange offer. If you are a
financial institution that is a participant in DTC's system you may make
book-entry delivery of old notes by causing DTC to transfer such old notes into
the exchange agent's account at DTC in accordance with DTC's procedures for
transfer.
    
 
     Although you may deliver old notes to the exchange agent in the exchange
offer through book-entry transfer at DTC, the letter of transmittal or a
facsimile of it, with any required signature guarantees or an agent's message
instead and any other required documents, must be transmitted to and received by
the exchange agent at one of the addresses set forth below under "exchange
agent," on or before the expiration date. If this is not possible, the
guaranteed delivery procedures described below must be complied with.
 
GUARANTEED DELIVERY PROCEDURES
 
   
     If you want to tender old notes and your old notes are not immediately
available, or time will not permit your old notes or other required documents to
reach the exchange agent before the expiration date, or you cannot complete the
procedure for book-entry transfer on a timely basis, you may tender your old
notes if
    
 
         - the tender is made through an eligible institution,
 
   
         - before the expiration date, the exchange agent received from the
           eligible institution the appropriate notice of guaranteed delivery,
           substantially in the
    
 
                                       20
<PAGE>   24
 
   
           form provided by us, by telegram, telex, facsimile transmission, mail
           or hand delivery, setting forth your name and address and the amount
           of old notes tendered, stating that the tender is being made by that
           notice. The notice of guaranteed delivery must guarantee that within
           five New York Stock Exchange trading days after the date of execution
           of the notice of guaranteed delivery, the certificates for all
           physically tendered old notes, in proper form for transfer, or a
           book-entry confirmation, as the case may be, together with a properly
           completed and duly executed letter of transmittal, or facsimile of
           the letter of transmittal or agent's message instead, with any
           required signature guarantees, and any other documents required by
           the appropriate letter of transmittal will be deposited by the
           eligible institution with the exchange agent and
    
 
   
         - the certificates for all physically tendered old notes, in proper
           form for transfer, or a book-entry confirmation, as the case may be,
           together with a properly completed and duly executed appropriate
           letter of transmittal, or facsimile of the letter of transmittal or
           agent's message instead, with any required signature guarantees, and
           all other documents required by the letter of transmittal, are
           received by the exchange agent within five New York Stock Exchange
           trading days after the date of execution of the notice of guaranteed
           delivery.
    
 
WITHDRAWAL RIGHTS
 
     You may withdraw tenders of old notes at any time before the expiration
date.
 
   
     For a withdrawal to be effective, a written notice of withdrawal must be
received by the exchange agent at the addresses set forth below under "exchange
agent". Any notice of withdrawal must:
    
 
     - specify the name of the person having tendered the old notes to be
       withdrawn,
 
     - identify the old notes to be withdrawn, including the principal amount in
       the case of 11 1/2% old notes or the principal amount at maturity in the
       case of the 12 3/8% old notes,
 
   
     - and where certificates for old notes have been transmitted, specify the
       name in which those old notes are registered, if different from that of
       the withdrawing holder.
    
 
   
     If certificates for old notes have been delivered or otherwise identified
to the exchange agent then, before the release of such certificates you must
also submit the serial numbers of the particular certificates to be withdrawn
and a signed notice of withdrawal with signatures guaranteed by an eligible
institution unless you are an eligible institution. If tendered old notes under
the procedure for book-entry transfer described above, the executed notice of
withdrawal, guaranteed by an eligible institution, unless you are an eligible
institution, must specify the name and number of the account at DTC to be
credited with the withdrawn old notes and otherwise comply with the procedures
of that facility. All questions as to the validity, form and eligibility,
including
    
 
                                       21
<PAGE>   25
 
   
time of receipt, of notices of withdrawal will be determined by us. Our
determination will be final and binding on all parties. Any old notes withdrawn
will be deemed not to have been validly tendered for exchange for purposes of
the exchange offer. Any old notes which you tender for exchange but which are
not exchanged for any reason will be returned to you without cost to you or, in
the case of old notes tendered by book-entry transfer into the exchange agent's
account at DTC pursuant to the book-entry transfer procedures described above,
such old notes will be credited to an account maintained with DTC for the old
notes) as soon as practicable after withdrawal. Properly withdrawn old notes may
be retendered by following one of the procedures described under "-- Procedures
for tendering old notes" above at any time on or before the expiration date.
    
 
CONDITIONS TO THE EXCHANGE OFFER
 
   
     Notwithstanding any other provision of the exchange offer, we will not be
required to accept for exchange, or to issue new notes in exchange for, the old
notes and may terminate or amend the exchange offer if at any time before the
acceptance of the old notes for exchange or the exchange of the new notes for
the old notes any of the following events occurs:
    
 
         (1) there shall be threatened, instituted or pending any action or
     proceeding before, or any injunction, order or decree shall have been
     issued by, any court or governmental agency or other governmental
     regulatory or administrative agency or commission,
 
   
              (a) seeking to restrain or prohibit the making or consummation of
                  the exchange offer or any other transaction contemplated by
                  the exchange offer, or assessing or seeking any damages as a
                  result of the exchange offer or any transaction contemplated
                  by the exchange offer, or
    
 
   
              (b) resulting in a material delay in our ability to accept for
                  exchange or exchange some or all of the old notes in the
                  exchange offer,
    
 
   
     or any statute, rule, regulation, order or injunction shall be sought,
     proposed, introduced, enacted, promulgated or deemed applicable to the
     exchange offer or any of the transactions contemplated by the exchange
     offer by any government or governmental authority, domestic or foreign, or
     any action shall have been taken, proposed or threatened, by any
     government, governmental authority, agency or court, domestic or foreign,
     that in our sole judgment might directly or indirectly result in any of the
     consequences referred to in clauses (a) or (b) above or, in our sole
     judgement, might result in the holders of new notes having obligations with
     respect to resales and transfers of new notes which are greater than those
     described in the interpretation of the SEC referred to in this prospectus,
     or would otherwise make it inadvisable to proceed with the exchange offer;
     or
    
 
                                       22
<PAGE>   26
 
         (2) there shall have occurred
 
              (a) any general suspension of or general limitation on prices for,
                  or trading in, securities on any national securities exchange
                  or in the over-the-counter market,
 
   
              (b) any limitation by any governmental agency or authority which
                  may adversely affect the ability of NTL to complete the
                  transactions contemplated by the exchange offer,
    
 
              (c) a declaration of a banking moratorium or any suspension of
                  payments in respect of banks in the United States or any
                  limitation by any governmental agency or authority which
                  adversely affects the extension of credit or
 
   
         (3) a commencement of a war, armed hostilities or other similar
     international calamity directly or indirectly involving the United States,
     or, in the case of any of the foregoing existing at the time of the
     commencement of the exchange offer, a material acceleration or worsening of
     those circumstances; or
    
 
         (4) any change or any development involving a prospective change shall
     have occurred or be threatened in the business, properties, assets,
     liabilities, financial condition, operations, results of operations or
     prospects of NTL and our subsidiaries taken as a whole that, in our
     reasonable judgment, is or may be adverse to us, or we shall have become
     aware of facts that, in our reasonable judgment, have or may have adverse
     significance with respect to the value of the old notes or the new notes;
 
   
which, in our reasonable judgment in any case, and regardless of the
circumstances, including any action by us, giving rise to that condition, makes
it inadvisable to proceed with the exchange offer and/or with such acceptance or
exchange or with that exchange.
    
 
   
     The foregoing conditions are for our sole benefit. Those conditions may be
asserted by us regardless of the circumstances giving rise to that condition or
may be waived by us in whole or in part at any time and from time to time in our
sole discretion. The failure by us at any time to exercise any of the foregoing
rights shall not be deemed a waiver of any of our rights and each of our rights
shall be deemed an ongoing right which may be asserted at any time and from time
to time.
    
 
     In addition, we will not accept for exchange any old notes tendered, and no
new notes will be issued in exchange for any such old notes, if at such time any

                                USE OF PROCEEDS
    
 
   
     We will not receive any cash proceeds from the exchange of old notes for
new notes in the exchange offer. We used the net proceeds of approximately
$606.5 million from the sale of the 11 1/2% old notes to repay a portion of the
indebtedness that we incurred under the new credit facility to fund the ComTel
acquisition. We used most of the net proceeds of approximately $242 million from
the sale of the 12 3/8% old notes to repay all the remaining indebtedness of
approximately $185 million that we incurred under the new credit facility to
fund the ComTel acquisition. We intend to use the balance of the net proceeds of
approximately $57 million from the sale of the 12 3/8% old notes to finance our
construction, capital expenditure and working capital requirements, including
debt service and repayment obligations. In addition, a portion of the net
proceeds may also be used to make acquisitions of businesses or assets related
to our business.

(1) The as adjusted column assumes that NTL uses a portion of the net proceeds
    of the offering of the 9 3/4% notes to repay the 13 1/4% Diamond notes
    (excluding the payment of any premium therefor). NTL may, however, use the
    proceeds for other corporate purposes as discussed elsewhere in this
    offering circular. As of December 31, 1998, the accreted value of the
    13 1/4% Diamond notes was approximately $259,159,000. The 13 1/4% Diamond
    notes are redeemable at the option of Diamond on September 30, 1999 at
    107.125% of the principal amount at maturity.

                              DESCRIPTION OF NOTES
    
 
   
GENERAL
    
 
   
     The 11 1/2% new notes will be issued under the 11 1/2% indenture, dated as
of November 2, 1998, between NTL and The Chase Manhattan Bank, as trustee. The
12 3/8% new notes will be issued under the 12 3/8% indenture, dated as of
November 6, 1993, between NTL and The Chase Manhattan Bank as trustee. The
following summary of selected provisions of the indentures is not complete and
is qualified in its entirety by reference to the indentures, including the
definitions in indentures of various terms used below. The definitions of some
terms used in the following summary are set forth below under "-- Definitions."
    
 
   
     In this section of the prospectus entitled "Description of Notes" when we
refer to NTL we are referring only to the parent company, NTL Incorporated and
not any of its subsidiaries.
    
 
   
     The old notes are, and the new notes will be, unsecured obligations of NTL,
ranking equal in right of payment with all senior unsecured Indebtedness of NTL
and senior in right of payment to all subordinated Indebtedness of NTL.
    
 
   
     The operations of NTL are conducted through its subsidiaries. NTL is
dependent upon the cash flow of its subsidiaries to meet its obligations,
including its obligations under the notes. As a result, the old notes are, and
the new notes will be effectively subordinated to all existing and future
indebtedness and other liabilities and commitments of NTL's subsidiaries with
respect to the cash flow and assets of those subsidiaries.
    
 
   
     Application will be made to list the new notes on the Luxembourg Stock
Exchange.
    
 
PRINCIPAL, MATURITY AND INTEREST
 
   
     The 11 1/2% new notes will be limited in aggregate principal amount to
$625,000,000. The 11 1/2% new notes will accrue interest at the rate of 11 1/2%
per annum. Interest on the 11 1/2% new notes will be payable in cash,
semi-annually in arrears, on April 1 and October 1 of each year, beginning on
April 1, 1999. Interest on the 11 1/2% new notes will be payable to the holders
of record on the immediately preceding March 15 in respect of interest payable
on the following April 1 and September 15 in respect of interest payable on the
following October 1. Interest on the 11 1/2% notes will accrue from November 2,
1998, or the most recent date to which interest has been paid or duly provided
for on the 11 1/2% old notes.
    
 
   
     The 12 3/8% new notes will be limited in aggregate principal amount at
maturity to $450,000,000. The 12 3/8% new notes will be issued at a substantial
discount from their principal amount at maturity. Until October 1, 2003, no
interest will accrue on the 12 3/8% new notes, but the Accreted Value of the
12 3/8% new notes will increase, representing amortization of original issue
discount, between the date of original issuance and October 1, 2003, on a
semiannual bond equivalent basis using a 360-day year comprised of twelve 30-day
months, such that the Accreted Value of the 12 3/8% new notes shall be equal to
the full principal amount at maturity of the 12 3/8% new notes on October 1,
    
 
                                       28

2003. From October 1, 2003, interest on the 12 3/8% new notes will accrue at the
rate of 12 3/8% per annum and will be payable in cash, semiannually in arrears,
on each April 1 and October 1, commencing April 1, 2004, to holders of record on
the immediately preceding March 15 in respect of interest payable on the
following April 1 and September 15 in respect of interest payable on the
following October 1.
    
 
   
     The Accreted Value of each 12 3/8% note on each semi-annual accrual date
will be as set forth below:

</TABLE>
    
 
   
     Interest on overdue principal and to the extent permitted by law on overdue
installments of interest will accrue at a rate equal to the rate borne by the
new notes. Interest will be computed on the basis of a 360-day year comprised of
twelve 30-day months. A reference to a payment of interest in respect of the new
notes includes a payment of special interest, if any, and a reference to a
payment of principal includes a reference to a payment of premium, if any.
    
 
   
     The new notes will be payable both as to principal and interest on
presentation of such new notes if in certificated form at the offices or
agencies of NTL maintained for such purpose within the City and State of New
York or, at the option of NTL, payment of interest may be made by check mailed
to the holders of the new notes at their respective addresses set forth in the
register of holders of new notes or, if a holder so requests, by wire transfer
of immediately available funds to an account previously specified in writing by
such holder to NTL and the trustee. Until otherwise designated by NTL, NTL's
office or agency in New York will be the offices of the trustee maintained for
such purpose. NTL has designated Chase Manhattan Bank Luxembourg S.A. to act as
paying agent in Luxembourg if the new notes are approved for listing on the
Luxembourg Stock Exchange. The new notes will be payable on maturity on October
1, 2008 at 100% of their principal amount and will be issued in registered form,
without coupons, and in denominations of $1,000 and integral multiples of
$1,000.
    
 
OPTIONAL REDEMPTION
 
   
     Except as referred to in this prospectus under "-- Covenants -- Additional
Amounts; Optional Tax Redemption," the notes are not redeemable at NTL's option
prior to October 1, 2003. Thereafter, the notes will be subject to redemption at
the option of NTL, in whole or in part, upon not less than 30 nor more than 60
days' notice, at the redemption prices set forth below, expressed as percentages
of principal amount,
    
 
                                       29

     In the case of a redemption of any class of notes referred to herein under
"-- Covenants -- Additional Amounts; Optional Tax Redemption," redemption of
such Notes shall be made at the redemption prices specified in the applicable
indenture plus accrued and unpaid interest, if any, to the applicable redemption
date.
    
 
MANDATORY REDEMPTION AND REPURCHASE
 
   
     NTL is not required to make mandatory redemption or sinking fund payments
with respect to the notes. NTL is required to make a Change of Control Offer and
an Asset Sale Offer with respect to a repurchase of the notes under the
circumstances described under the captions "Change of control" and "Asset
sales," respectively.
    
 
CHANGE OF CONTROL
 
   
     If a Change of Control Triggering Event occurs, each holder of notes shall
have the right to require NTL to repurchase all or any part of such holder's
notes equal to $1,000 or an integral multiple of $1,000, pursuant to the Change
of Control Offer at a purchase price equal to 101% of the principal amount of
those notes plus accrued and unpaid interest, if any, to the date of purchase.
In the case of repurchases of 12 3/8% notes prior to October 1, 2003, the
purchase price will be 101% of the Accreted Value of those notes as of the date
of purchase. The payment shall be referred to as the Change of Control Payment.
Within 40 days following any Change of Control Triggering Event, NTL shall mail
a notice to each holder, and, if and as long as the notes are listed on the
Luxembourg Stock Exchange, publish a notice in one leading newspaper with
circulation in Luxembourg, stating:
    
 
   
         (1) that the Change of Control Offer is being made pursuant to the
     covenant entitled Change of Control and that all notes tendered will be
     accepted for payment;
 
         (2) the purchase price and the purchase date, which shall be no earlier
     than 30 days nor later than 40 days from the date such notice is mailed.
     This date is referred to as the Change of Control Payment Date;
    
 
   
         (3) that any notes not tendered will continue to accrue interest and,
     if applicable, the Accreted Value of any 12 3/8% new notes not tendered
     will continue to increase as provided in those notes;
    
 
   
         (4) that, unless NTL defaults in the payment of the Change of Control
     Payment, all notes accepted for payment pursuant to the Change of Control
     Offer shall cease to accrue interest after the Change of Control Payment
     Date and, if
    
 
                                       30
<PAGE>   34
 
   
     applicable, the Accreted Value of any 12 3/8% notes tendered will cease to
     increase as provided in those notes;
    
 
   
         (5) that holders electing to have any notes purchased pursuant to a
     Change of Control Offer will be required to surrender the notes, with the
     form entitled Option of Holder to Elect Purchase on the reverse of the
     notes completed, to the paying agent at the address specified in the notice
     prior to the close of business on the third Business Day preceding the
     Change of Control Payment Date;
    
 
   
         (6) that holders will be entitled to withdraw their election if the
     paying agent receives, not later than the close of business on the second
     Business Day preceding the Change of Control Payment Date, a telegram,
     telex, facsimile transmission or letter setting forth the name of the
     holder, the principal amount of notes delivered for purchase, and a
     statement that such holder is withdrawing his election to have such notes
     purchased; and
    
 
   
         (7) that holders whose notes are being purchased only in part will be
     issued new 11 1/2% notes equal in principal amount to the unpurchased
     portion of the 11 1/2% notes surrendered, which unpurchased portion must be
     equal to $1,000 in principal amount or an integral multiple of $1,000.
    
 
   
     NTL will comply with the requirements of the securities laws and
regulations thereunder to the extent those laws and regulations are applicable
in connection with the repurchase of the notes in connection with a Change of
Control Triggering Event.
    
 
   
     On the Change of Control Payment Date, NTL will, to the extent lawful,
    
 
   
         (1) accept for payment notes or portions of notes tendered pursuant to
     the Change of Control Offer,
    
 
   
         (2) deposit with the Paying Agent an amount equal to the Change of
     Control Payment in respect of all notes or portions of notes so tendered
     and
    
 
   
         (3) deliver or cause to be delivered to the trustee the notes so
     accepted together with an Officers' Certificate stating the notes or
     portions of notes tendered to NTL.
    
 
   
     The paying agent shall promptly mail to each holder of notes so accepted,
or, if such a holder requests, wire transfer immediately available funds to an
account previously specified in writing by such holder to NTL and the paying
agent, payment in an amount equal to the purchase price for such notes. The
trustee shall promptly authenticate and mail to each holder a new note equal in
principal amount to any unpurchased portion of the notes surrendered, if any;
provided that each such new note shall be in a principal amount of $1,000 or an
integral multiple of $1,000. NTL will publicly announce the results of the
Change of Control Offer on or as soon as practicable after the Change of Control
Payment Date.
    
 
   
     Except as described above with respect to a Change of Control Triggering
Event, the indentures do not contain any other provisions that permit the
holders of the notes to require that NTL repurchase or redeem the notes in the
event of a takeover,
    
 
                                       31
<PAGE>   35
 
   
recapitalization or similar restructuring. The indentures contain covenants
which may afford holders of the notes protection in the event of a highly
leveraged transaction, reorganization, restructuring, merger or similar
transaction, including the Change of Control provision described above and the
provisions described under "-- Incurrence of Indebtedness and Issuance of
Preferred Stock" and "-- Merger, Consolidation or Sale of Assets" below. Each of
those covenants is, however, subject to exceptions which may permit NTL to be
involved in a highly leveraged transaction that may adversely affect the holders
of the notes.
    
 
   
     The Change of Control Offer requirement of the notes may in certain
circumstances make more difficult or discourage a takeover of NTL, and, thus,
the removal of incumbent management. Management has not entered into any
agreement or plan involving a Change of Control, although it is possible that
NTL would decide to do so in the future. Subject to the limitations discussed
below, NTL could, in the future, enter into various transactions including
acquisitions, refinancings or other recapitalizations, that would not constitute
a Change of Control Triggering Event under the indentures, but that could
increase the amount of indebtedness outstanding at such time or otherwise affect
NTL's capital structure or credit ratings.
    
 
   
     The indentures for our other outstanding senior notes and convertible notes
also contain change of control provisions.
    
 
   
     NTL's ability to pay cash to the holders of notes pursuant to a Change of
Control Offer may be limited by NTL's then existing financial resources. See
"Risk Factors -- Our substantial leverage could adversely affect the financial
health of the company" and "-- We are a holding company that is dependant upon
cash flow from our subsidiaries -- our ability to access that cash flow may be
limited in some circumstances." The new credit facility does, and any future
credit agreements or other agreements relating to indebtedness of NTL may,
contain prohibitions or restrictions on NTL's ability to effect a Change of
Control Payment. In the event a Change of Control Triggering Event occurs at a
time when such prohibitions or restrictions are in effect, NTL could seek the
consent of its lenders to the purchase of notes and other Indebtedness
containing change of control provisions or could attempt to refinance the
borrowings that contain such prohibition. If NTL does not obtain such a consent
or repay such borrowings, NTL will be effectively prohibited from purchasing
notes. In such case, NTL's failure to purchase tendered notes would constitute
an Event of Default under the indentures. Moreover, the events that constitute a
Change of Control or require an Asset Sale Offer under the indentures constitute
events of default under the Credit Facility and may also constitute events of
default under future debt instruments or credit agreements of NTL or NTL's
Subsidiaries. Such events of default may permit the lenders under such debt
instruments or credit agreements to accelerate the debt and, if such debt is not
paid or repurchased, to enforce their security interests in what may be all or
substantially all of the assets of NTL's Subsidiaries. Any such enforcement may
limit NTL's ability to raise cash to repay or repurchase the notes.
    
 
   
     NTL will not be required to make a Change of Control Offer in the event NTL
enters into a transaction with management or their affiliates who are Permitted
Holders.
    
 
                                       32
<PAGE>   36
 
   
The definition of Change of Control includes a phrase relating to the sale,
lease, transfer, conveyance or other disposition of all or substantially all of
NTL's assets. Although there is a developing body of case law interpreting the
phrase substantially all, there is no precise established definition of the
phrase under applicable law. Accordingly, the ability of a holder of notes to
require NTL to repurchase those notes as a result of a sale, lease, transfer,
conveyance or other disposition of less than all of the assets of NTL and its
Subsidiaries to another Person may be uncertain.
    
 
ASSET SALES
 
   
     The indentures provide that NTL will not and will not permit any of its
Restricted Subsidiaries to cause, make or suffer to exist any Asset Sale, unless
    
 
         (1) no Default exists or is continuing immediately prior to and after
             giving effect to such Asset Sale,
 
   
         (2) NTL 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 covenant 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
    
 
   
         (3) at least 80% of the consideration therefor received by NTL or the
             Restricted Subsidiary is in the form of
    
 
               (a) Cash Equivalents,
 
               (b) Replacement Assets,
 
   
               (c) publicly traded Equity Interests of a Person who is, directly
                   or indirectly, engaged primarily in one or more Cable
                   Businesses; provided, however, that NTL or the Restricted
                   Subsidiary shall Monetize the Equity Interests by sale to one
                   or more Persons, other than to NTL or a Subsidiary NTL, at a
                   price not less than the fair market value thereof within 180
                   days of the consummation of the Asset Sale, or
    
 
               (d) any combination of the foregoing clauses (a) through (c);
 
               provided, however, that the amount of
 
   
               (x) any liabilities, as shown on NTL's or the Restricted
                   Subsidiary's most recent balance sheet or in the notes
                   thereto, of NTL 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 NTL or any
                   Restricted Subsidiary from such transferee that are within
                   five Business Days converted by NTL or the Restricted
                   Subsidiary into cash, shall be
    
 
                                       33
<PAGE>   37
 
   
                 deemed to be Cash Equivalents, to the extent of the Cash
                 Equivalents received in such conversion, for purposes of this
                 clause (3).
    
 
   
     Within 360 days after any Asset Sale, NTL, or the Restricted Subsidiary, as
the case may be, will cause the Net Proceeds from the Asset Sale
    
 
         (1) to be used to permanently reduce Indebtedness of a Restricted
             Subsidiary or
 
         (2) to be invested or reinvested in Replacement Assets.
 
   
     Pending final application of any Net Proceeds, NTL may temporarily reduce
revolving credit borrowings or otherwise invest those Net Proceeds in any manner
that is not prohibited by the indenture.
    
 
   
     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, NTL will make 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 that may be purchased out of the
Excess Proceeds:
    
 
         (1) 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
 
   
         (2) with respect to the notes, at an offer price in cash in an amount
             equal to 100% of the outstanding principal amount thereof plus
             accrued and unpaid interest, if any, to the date fixed for the
             closing of such offer, or, in the case of repurchases of 12 3/8%
             notes prior to October 1, 2003, at a purchase price equal to 100%
             of the Accreted Value of those notes as of the date of repurchase
             in accordance with the procedures set forth in the indentures.
    
 
   
     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 NTL 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 then the remaining Excess Proceeds
will 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
the trustee will select the notes to be purchased from the amount allocated to
the notes on the basis set forth under "Selection and notice" below. Upon
completion of such offers to purchase each of the notes and the Other Qualified
Notes, the amount of Excess Proceeds will be reset at zero.
    
 
   
     Notwithstanding the foregoing, NTL and its Subsidiaries may
    
 
   
         (1) sell, lease, transfer, convey or otherwise dispose of assets or
             property acquired after October 14, 1993, by NTL or any Subsidiary
             in a sale-and-leaseback transaction so long as the proceeds of such
             sale are applied
    
 
                                       34
<PAGE>   38
 
              within five Business Days to permanently reduce Indebtedness of a
              Restricted Subsidiary or if there is no such Indebtedness or such
              proceeds exceed the amount of such Indebtedness then such proceeds
              or excess proceeds are reinvested in Replacement Assets within 360
              days after such sale, lease, transfer, conveyance or disposition,
 
         (2) (x) swap or exchange assets or property with a Cable Controlled
             Subsidiary or
 
   
               (y) issue, sell, lease, transfer, convey or otherwise dispose of
                   equity securities of any of NTL's Subsidiaries to a Cable
                   Controlled Subsidiary, in each of cases (x) and (y) so long
                   as
    
 
   
                    (A) the ratio of Indebtedness to Annualized Pro Forma EBITDA
                        of NTL after such transaction is equal to or less than
                        the ratio of Indebtedness to Annualized Pro Forma EBITDA
                        of NTL immediately preceding such transaction; provided,
                        however, that if the ratio of Indebtedness to Annualized
                        Pro Forma EBITDA of NTL immediately preceding such
                        transaction is 6:1 or less, then the ratio of
                        Indebtedness to Annualized Pro Forma EBITDA of NTL 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 NTL 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 NTL and its Restricted Subsidiaries
                             immediately prior to such transaction or
    
 
                        (II) the assets so contributed consist solely of Cable
                             Assets and the value of the Capital Stock received,
                             immediately after and giving effect to such
                             transaction, as determined by an investment banking
                             firm of recognized standing with knowledge of the
                             Cable Business, equals or exceeds the value of the
                             Cable Assets exchanged for such Capital Stock, or
 
   
         (3) issue, sell, lease, transfer, convey or otherwise dispose of Equity
             Interests of NTL, or any Capital Stock Sales Proceeds therefrom, to
             any Person including Non-Restricted Subsidiaries.

<PAGE>   39
 
   
SELECTION AND NOTICE
    
 
   
     If less than all of the notes are to be redeemed at any time, selection of
notes for redemption will be made by the trustee in compliance with the
requirements of any securities exchange on which the notes are listed. In the
absence of any requirements of any securities exchange or if the notes are not
so listed, selection of the note to be redeemed will be made on a pro rata
basis, provided that no notes of $1,000 or less shall be redeemed in part.
Notice of redemption shall be mailed by first class mail at least 30 but not
more than 60 days before the redemption date to each holder of notes to be
redeemed at its registered address. If any note is to be redeemed in part only,
the notice of redemption that relates to such note shall state the portion of
the principal amount thereof to be redeemed. A new note in principal amount
equal to the unredeemed portion thereof will be issued in the name of the holder
thereof upon cancellation of the original note. On and after the redemption
date, interest ceases to accrue and, if applicable, the Accreted Value of any
12 3/8% notes tendered will cease to increase as provided in those notes on
notes or portions of them called for redemption.
    
 
COVENANTS
 
   Restricted Payments
 
   
     The indentures provide that NTL will not, and will not permit any of its
Restricted Subsidiaries to, directly or indirectly:
    
 
   
         (1) declare or pay any dividend or make any distribution on account of
             NTL's or any of its Restricted Subsidiaries' Equity Interests
             (other than
    
 
   
               (x) dividends or distributions payable in Equity Interests (other
                   than Disqualified Stock) of NTL or such Restricted Subsidiary
                   or
    
 
   
               (y) dividends or distributions payable to NTL or any Wholly Owned
                   Subsidiary of NTL, or
    
 
               (z) pro rata dividends or pro rata distributions payable by a
                   Restricted Subsidiary);
 
   
         (2) purchase, redeem or otherwise acquire or retire for value any
             Equity Interests of NTL, other than any such Equity Interests owned
             by NTL or any Wholly Owned Subsidiary of NTL;
    
 
   
         (3) voluntarily purchase, redeem or otherwise acquire or retire for
             value any Indebtedness that is subordinated to the notes; or
    
 
   
         (4) make any Restricted Investment.
    
 
   
             All such payments and other actions set forth in clauses (1)
             through (4) above are collectively referred to as Restricted
             Payments.

<PAGE>   40
 
   
NTL or the Restricted Subsidiary may make a Restricted Payment if, at the time
of such Restricted Payment:
    
 
               (a) no Default or Event of Default shall have occurred and be
                   continuing or would occur as a consequence thereof; and
 
   
               (b) such Restricted Payment, together with the aggregate of all
                   other Restricted Payments made by NTL and its Restricted

                      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 the
                      applicable 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

                           of Directors.
    
 
     The foregoing provisions will not prohibit
 
   
         (1) 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 the indenture;

assume, guaranty or otherwise become directly or indirectly liable with respect
to any Indebtedness, including Acquired Debt, and that NTL will not issue any
Disqualified Stock and will not permit any of its Restricted Subsidiaries to

             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.
    
 
     The foregoing limitations will not apply to

              are, or the credit support provided by any such Indebtedness is,
              in each case, used to finance the construction, capital
              expenditure and working capital needs of a Cable Business,
              including, without limitation, payments made pursuant

              of, such Refinancing Indebtedness shall not exceed the principal
              amount of Indebtedness so extended, refinanced, renewed, replaced
              or refunded plus the amount of reasonable expenses incurred in
              connection therewith;

              paragraph or the preceding paragraph that are being hedged
              thereby, and not for speculation and that the aggregate notional

              such Restricted Subsidiary, or other Persons providing funding on
              their behalf, on a pro rata basis and on substantially identical
              principal financial terms, provided, however, that if any such
              Restricted Subsidiary that is the payee of any such Indebtedness
              ceases to be a Restricted Subsidiary or transfers such
              Indebtedness, other than to NTL or a Restricted Subsidiary of NTL,
              such events shall be deemed, in each case, to constitute the

              operation of a Cable Business.
    
 
   
     Any redesignation of a Non-Restricted Subsidiary as a Restricted Subsidiary
shall be deemed for purposes of the foregoing covenant to be an incurrence of
Indebtedness by NTL 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 NTL or one of its
Restricted Subsidiaries.

     The indentures provide that neither NTL nor any of its Restricted
Subsidiaries may directly or indirectly create, incur, assume or suffer to exist

             issued and secured by such Lien shall not be secured by any
             property or assets of

                  Issuance of Preferred Stock" covenant, provided that the
                  provisions of such agreement permit any action referred to in
                  clause (1) above in aggregate amounts sufficient to enable the
                  payment of interest and principal and mandatory repurchases
                  pursuant to the terms of the indentures and the notes but
                  provided further that:
    
 
                      (x) any such agreement may nevertheless encumber, prohibit
                          or restrict any action referred to in clause (1) 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

              (4) applicable law,
 
   
              (5) any instrument governing Indebtedness or Capital Stock of a
                  Person acquired by NTL or any of its Subsidiaries as in effect
                  at the time of such acquisition, except to the extent such
                  Indebtedness was incurred in connection with such acquisition,
                  which encumbrance or restriction is not applicable to any
                  Person, or the properties or assets of any Person, other than
                  the Person, or the property or assets of the Person, so
                  acquired; provided that the EBITDA of such Person is not taken
                  into account in determining whether such acquisition was
                  permitted by the terms of the indentures,
    
 
              (6) customary nonassignment provisions in leases entered into in

                  as such provisions are determined by a resolution of the Board
                  of Directors to be, at the time of such determination,
                  customary for such agreements,
 
   
              (8) with respect to clause (c) above, purchase money obligations
                  for property acquired in the ordinary course of business or
                  the provisions of any agreement with respect to any Asset
                  Sale, or transaction which, but for its size, would be an
                  Asset Sale, solely with respect to the assets being sold, or
    
 
              (9) 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.
 
   
   Merger, consolidation or sale of assets
    
 
   
     The indentures provide that NTL may not consolidate or merge with or into,
whether or not NTL is the surviving corporation, or sell, assign, transfer,
lease, convey or otherwise dispose of all or substantially all of its properties
or assets in one or more related transactions to, another corporation, Person or
entity unless
    
 
   
         (1) NTL is the surviving corporation or the entity or the Person formed
             by or surviving any such consolidation or merger, if other than
             NTL, or to which such sale, assignment, transfer, lease, conveyance
             or other disposition shall have been made is a corporation
             organized or existing under the laws of the United Kingdom, the
             Netherlands, the Netherlands Antilles, Bermuda or the Cayman
             Islands or of the United States, any state thereof or the District
             of Columbia;
    
 
   
         (2) the entity or Person formed by or surviving any such consolidation
             or merger, if other than NTL, or the entity or Person to which such
             sale, assignment, transfer, lease, conveyance or other disposition
             will have been
    
 
                                       44

              made assumes all the Obligations, including the due and punctual
              payment of Additional Amounts as defined in the indentures if the
              surviving corporation is a corporation organized or existing under
              the laws of the United Kingdom, the Netherlands, the Netherlands
              Antilles, Bermuda or the Cayman Islands, of NTL, pursuant to a
              supplemental indenture in a form reasonably satisfactory to the
              Trustee, under the notes and the indentures;
    
 
         (3) immediately after such transaction no Default or Event of Default
             exists;
 
   
         (4) NTL or any entity or Person formed by or surviving any such
             consolidation or merger, or to which such sale, assignment,
             transfer, lease, conveyance or other disposition will have been
             made will have a ratio of Indebtedness to Annualized Pro Forma
             EBITDA equal to or less than the ratio of Indebtedness to
             Annualized Pro Forma EBITDA of NTL immediately preceding the
             transaction provided, however, that if the ratio of Indebtedness to
             Annualized Pro Forma EBITDA of NTL immediately preceding such
             transaction is 6:1 or less, then the ratio of Indebtedness to
             Annualized Pro Forma EBITDA of NTL may be 0.5 greater than such
             ratio immediately preceding such transaction; and
    
 
   
         (5) such transaction would not result in the loss of any material
             authorization or Material License of NTL or its Subsidiaries.
    
 
   Additional Amounts; Optional Tax Redemption
 
   
     The indentures provide that the "Payment of Additional Amounts" provision
in the indentures, relating to United Kingdom, Netherlands, Netherlands
Antilles, Bermuda and Cayman Islands withholding and other United Kingdom,
Netherlands, Netherlands Antilles, Bermuda and Cayman Islands taxes, and the
"Optional Tax Redemption" provision in the indentures, relating to NTL's option
to redeem the notes under specified circumstances if Additional Amounts are
payable, apply to the notes in specified circumstances. The provisions of the
indentures relating to the payment of Additional Amounts will only apply in the
event that NTL becomes, or a successor to NTL is, a corporation organized or
existing under the laws of the United Kingdom, the Netherlands, the Netherlands
Antilles, Bermuda or the Cayman Islands. In such circumstances, all payments
made by NTL on the notes will be made without deduction or withholding, 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 NTL under the notes, NTL
will pay or cause to be paid such Additional Amounts as may be necessary in
order that the net amounts received by a holder of the notes after such
deduction or withholding shall be not less than the
    
 
                                       45
<PAGE>   49
 
   
amounts specified in the notes to which the holder of such notes is entitled;
provided, however, that NTL shall not be required to make any payment of
Additional Amounts for or on account of:
    
 
         (1) any tax, assessment or other governmental charge to the extent such
             tax, assessment or other governmental charge would not have been
             imposed but for
 
   
               (a) 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 the
                   notes or the receipt of amounts payable in respect of the
                   notes 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 had a permanent establishment
                   therein or
    
 
   
              (b) the presentation of the notes, 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 the notes been presented on the last
                  day of such period of 30 days;
    
 
   
         (2) any governmental charge that is imposed or withheld by reason of
             the failure to comply by the holder of the notes or, if different,
             the beneficial owner of the interest payable on the notes, with a
             timely request of NTL addressed to such holder or beneficial owner
             to provide information, documents or other evidence concerning the
             nationality, 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;
    
 
         (3) any estate, inheritance, gift, sales, transfer, personal property
             or similar tax assessment or other governmental charge;
 
   
         (4) 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 note or withholding from the proceeds of
             a sale or exchange of a note;
    
 
                                       46
<PAGE>   50
 
   
         (5) 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 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;
    
 
   
         (6) any tax, assessment or other governmental charge imposed on a
             holder that is not the beneficial owner of a 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 note;
    
 
         (7) any combination of items (1), (2), (3), (4), (5) and (6) above;
 
   
nor shall Additional Amounts be paid with respect to any payment of the
principal of, or any interest on the notes 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 the notes.
    
 
   
     The notes may be redeemed at the option of NTL, in whole but not in part,
upon not less than 30 nor more than 60 days notice, at any time if the
circumstances set forth below occur. The redemption price will be equal to the
principal amount of the notes plus accrued and unpaid interest to the date fixed
for redemption or in the case of redemption of 12 3/8% notes prior to October 1,
2003, at a redemption price equal to 100% of the Accreted Value of those notes
as of the date of purchase if after the Issuance Date there has occurred any
change in or amendment to the laws, or any regulations or official rulings
promulgated thereunder, of the United Kingdom, the Netherlands, the Netherlands
Antilles, Bermuda or the Cayman Islands, or any political subdivision or taxing
authority thereof or therein, or any change in or amendment to the official
application or interpretation of such laws, regulation or rulings which becomes
effective after the Issuance Date, as a result of which NTL is or would be so
required on the next succeeding Interest Payment Date to pay Additional Amounts
with respect to the notes 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 and
such Withholding Tax is imposed at a rate that exceeds the rate, if any, at
which Withholding Tax was imposed on the Issuance Date provided, that,
    
 
   
         (1) 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,
             Netherlands, 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 Issuance Date,
    
 
                                       47
<PAGE>   51
 
   
         (2) no such notice of redemption may be given earlier than 90 days
             prior to the earliest date on which NTL would be obliged to pay
             such Additional Amounts were a payment in respect of the notes then
             due,
    
 
   
         (3) at the time such notice of redemption is given, such obligation to
             pay such Additional Amount remains in effect and
    
 
   
         (4) the payment of such Additional Amounts cannot be avoided by the use
             of any reasonable measures available to NTL.
    
 
   
     The notes may also be redeemed, in whole but not in part, at any time if
the circumstances described below occur. The redemption price will be equal to
the principal amount of the notes plus accrued and unpaid interest to the date
fixed for redemption or in the case of redemption of 12 3/8% notes prior to
October 1, 2003, at a redemption price equal to 100% of the Accreted Value of
those notes as of the date of purchase if the Person formed after the Issuance
Date by a consolidation, amalgamation, reorganization, reconstruction or other
similar arrangement of NTL or the Person into which NTL is merged after the
Issuance Date or to which NTL conveys, transfers or leases its properties and
assets after the Issuance substantially as an entirety 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 Notes with respect to
Withholding Tax 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. 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.
    
 
   
     NTL will also pay, or make available for payment, to holders on the
redemption date any Additional Amounts resulting from the payment of such
redemption price.
    
 
   Transactions with Affiliates
 
   
     The indentures provide that NTL will not, and will not permit any of its
Restricted Subsidiaries to enter into an Affiliate Transaction. This prohibits
NTL and any Restricted Subsidiary to sell, lease, transfer or otherwise dispose
of any of its properties or assets to, or purchase any property or assets from,
or enter into or amend any contract, agreement, understanding, loan, advance or
guarantee with, or for the benefit of, any Affiliate, unless
    
 
   
         (1) such Affiliate Transaction is on terms that are no less favorable
             to NTL or the relevant Subsidiary than those that could have been
             obtained in a comparable transaction by NTL or such Subsidiary with
             an unrelated Person and
    
 
                                       48
<PAGE>   52
 
   
         (2) NTL delivers to the trustee
    
 
               (a) with respect to any Affiliate Transaction involving aggregate
                   payments in excess of $1 million or any series of Affiliate
                   Transactions with an Affiliate involving aggregate payments
                   in excess of $1 million, a resolution of the Board of
                   Directors set forth in an Officers' Certificate certifying
                   that such Affiliate Transaction complies with clause (1)
                   above and such Affiliate Transaction is approved by a
                   majority of the disinterested directors on the Board of
                   Directors and
 
   
              (b) with respect to any Affiliate Transaction or any series of
                  Affiliate Transactions involving aggregate payments in excess
                  of $25 million, an opinion as to the fairness to NTL or the
                  Subsidiary from a financial point of view issued by an
                  investment banking firm of national standing with high yield
                  experience together with an Officers' Certificate to the
                  effect that such opinion complies with this clause (ii);
    
 
provided, however, that notwithstanding the foregoing provisions, the following
shall not be deemed to be Affiliate Transactions:
 
   
         (1) any employment agreement entered into by NTL or any of its
             Subsidiaries in the ordinary course of business and consistent with
             the past practice of NTL or its predecessor or such Subsidiary;
    
 
   
         (2) transactions between or among NTL and/or its Restricted
             Subsidiaries;
    
 
   
         (3) transactions permitted by the provisions of the indentures
             described above under the covenant "Restricted Payments;"
    
 
   
         (4) Liens permitted under the Liens covenant which are granted by NTL
             or any of its Subsidiaries to an unrelated Person for the benefit
             of NTL or any other Subsidiary of NTL;
    
 
         (5) any transaction pursuant to an agreement in effect on the Issuance
             Date;
 
         (6) the incurrence of Indebtedness by a Restricted Subsidiary where
             such Indebtedness is owed to the holders of the Equity Interests of
             such Restricted Subsidiary on a pro rata basis and on substantially
             identical principal financial terms;
 
   
         (7) management, operating, service or interconnect agreements entered
             into in the ordinary course of business with any Cable Business in
             which NTL or any Restricted Subsidiary has an Investment and which
             is not a Cable Controlled Subsidiary, and of which no Affiliate of
             NTL is an Affiliate other than as a result of such Investment; and
    
 
         (8) any tax sharing agreement.

   Reports
 
   
     Whether or not required by the rules and regulations of the SEC, so long as
any notes are outstanding, NTL will file with the SEC and furnish to the holders
of SEC 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 of
those reports under the Exchange Act for foreign private issuers in the event
NTL 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 by NTL's
certified independent accountants, in each case, as required by the rules and
regulations of the SEC as in effect on the Issuance Date. If and as long as the
SEC notes are listed on the Luxembourg Stock Exchange, copies of such reports
will also be available at the specified office of the Luxembourg Agent. NTL does
not publish unconsolidated financial reports.
    
 
EVENTS OF DEFAULT AND REMEDIES
 
   
     The indentures provide that each of the following constitutes an Event of
Default:
    
 
   
         (1) default for 30 days in the payment when due of interest and
             Additional Amounts, if applicable, on the 11 1/2% notes;
    
 
         (2) default in payment when due of principal on the 11 1/2% notes;
 
   
         (3) failure by NTL to comply with the provisions described under the
             covenants "Change of control," "Restricted payments" or "Incurrence
             of Indebtedness and issuance of Preferred Stock";
    
 
   
         (4) failure by NTL for 60 days after notice to comply with certain
             other covenants and agreements contained in the indentures or the
             notes;
    
 
   
         (5) default under any mortgage, indenture or instrument under which
             there may be issued or by which there may be secured or evidenced
             any Indebtedness for money borrowed by NTL or any of its Restricted
             Subsidiaries, or the payment of which is guaranteed by NTL or any
             of its Restricted Subsidiaries, whether such Indebtedness or
             guarantee now exists, or is created after the Issuance Date, which
             default
    
 
   
               (a) is caused by a failure to pay when due principal or interest
                   on such Indebtedness within the grace period provided in such
                   Indebtedness, which Payment Default continues beyond any
                   applicable grace period or
    
 
               (b) results in the acceleration of such Indebtedness prior to its
                   express maturity and, in each case, the principal amount of
                   any such Indebtedness, together with the principal amount of
                   any other such Indebtedness under which there has been a
                   Payment Default or the maturity of which has been so
                   accelerated, aggregates $10 million or more;
 
                                       50
<PAGE>   54
 
   
         (6) failure by NTL or any Restricted Subsidiary of NTL to pay final
             judgments (other than any judgment as to which a reputable
             insurance company has accepted full liability) aggregating in
             excess of $5 million, which judgments are not stayed within 60 days
             after their entry;
    
 
   
         (7) certain events of bankruptcy or insolvency with respect to NTL or
             any of its Material Subsidiaries; and
    
 
         (8) the revocation of a Material License.
 
   
     If any Event of Default occurs and is continuing, the trustee or the
holders of at least 25% in principal amount of then outstanding class of notes
may declare all the applicable class notes to be due and payable immediately.
Notwithstanding the foregoing, in the case of an Event of Default arising from
certain events of bankruptcy or insolvency, with respect to NTL or any Material
Subsidiary, all outstanding notes will become due and payable without further
action or notice. Holders of the notes may not enforce the indentures or the
notes except as provided in the indentures. Subject to certain limitations,
holders of a majority in principal amount of outstanding notes may direct the
trustee in its exercise of any trust or power. The trustee may withhold from
holders of the notes notice of any continuing Default or Event of Default,
except a Default or Event of Default relating to the payment of principal or
interest, if it determines that withholding notice is in their interest.
    
 
   
     The holders of a majority in aggregate principal amount of each class of
notes then outstanding by notice to the trustee may on behalf of the holders of
all of the applicable class of notes waive any existing Default or Event of
Default and its consequences under the indenture except a continuing Default or
Event of Default in the payment of interest on, or the principal of, the
applicable class of notes.
    
 
   
     NTL is required to deliver to the trustee annually a statement regarding
compliance with the indenture, and NTL is required, upon becoming aware of any
Default or Event of Default, to deliver to the trustee a statement specifying
such Default or Event of Default.
    
 
NO PERSONAL LIABILITY OF DIRECTORS, OFFICERS, EMPLOYEES AND SHAREHOLDERS
 
   
     No director, officer, employee, incorporator or shareholder of NTL, as
such, shall have any liability for any Obligations of NTL under the notes or the
indentures or for any claim based on, in respect of, or by reason of, such
Obligations or their creation. Each holder of the notes by accepting a note
waives and releases all such liability. The waiver and release are part of the
consideration for issuance of the notes. Such waiver may not be effective to
waive liabilities under the federal securities laws, and it is the view of the
commission that a waiver of such liabilities is against public policy.
    
 
DEFEASANCE AND DISCHARGE OF THE INDENTURE AND THE NOTES
 
   
     NTL may cause the defeasance of the notes if NTL irrevocably deposits, or
causes to be deposited, in trust with the trustee or the Paying Agent, at any
time prior to the stated maturity of the notes or the date of redemption of all
the outstanding notes, as
    
 
                                       51
<PAGE>   55
 
   
trust funds in trust, money or direct noncallable obligations of or guaranteed
by the United States of America in an amount sufficient, in the opinion of a
nationally recognized firm of independent public accountants, without
reinvestment thereof, to pay timely and discharge the entire principal of or, if
applicable, all amounts payable in respect of Accreted Value, the then
outstanding notes and all interest due thereon to maturity or redemption. The
indenture will then cease to be of further effect as to all outstanding notes
except, among other things, as to
    
 
   
         (1) remaining rights of registration of transfer and substitution and
             exchange of the notes,
    
 
   
         (2) rights of holders to receive payment of principal of and interest
             on the notes, and
    
 
   
         (3) the rights, obligations and immunities of the trustee.
    
 
     In order to exercise Defeasance:
 
   
         (1) NTL shall have delivered to the trustee an Opinion of Counsel
             reasonably acceptable to the trustee confirming that
    
 
   
               (a) NTL has received from, or there has been published by, the
                   Internal Revenue Service, a ruling or
    
 
   
               (b) since the date of the applicable indenture, 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;
    
 
   
         (2) no Event of Default shall have occurred and be continuing on the
             date of such deposit, other than an Event of Default resulting from
             the borrowing of funds to be applied to such deposit, or insofar as
             Events of Default from bankruptcy or insolvency events are
             concerned, at any time in the period ending on the 91st day after
             the date of deposit;
    
 
   
         (3) such Defeasance shall not result in a breach or violation of, or
             constitute a default under, any material agreement or instrument,
             other than the indenture, to which NTL or any of its Subsidiaries
             is a party or by which NTL or any of its Subsidiaries is bound;
    
 
   
         (4) NTL shall have delivered to the trustee an Opinion of Counsel to
             the effect that after the 91st day following the deposit, the trust
             funds will not be subject to the effect of any applicable
             bankruptcy, insolvency, reorganization or similar laws affecting
             creditors' rights generally;
    
 
   
         (5) NTL shall have delivered to the trustee an Officers' Certificate
             stating that the deposit was not made by NTL with the intent of
             preferring the holders
    
 
                                       52
<PAGE>   56
 
   
             of 11 1/2% notes over the other creditors of NTL with the intent of
             defeating, hindering, delaying or defrauding creditors of NTL or
             others;
    
 
   
         (6) the deposit shall not result in NTL, the trustee or the trust being
             subject to the Investment Company Act;
    
 
   
         (7) holders of the notes will have a valid, perfected and unavoidable,
             under applicable bankruptcy or insolvency laws, subject to the
             passage of time referred to in clause (4) above, first priority
             security interest in the trust funds; and
    
 
   
         (8) NTL shall have delivered to the trustee an Officers' Certificate
             and an Opinion of Counsel, each stating that all conditions
             precedent relating to the Defeasance have been complied with.
    
 
UNCLAIMED MONEY, PRESCRIPTION
 
   
     If money deposited with the trustee or Paying Agent for the payment of
principal or interest remains unclaimed for two years, the trustee and the
Paying Agent shall pay the money back to NTL at its written request. After that,
holders of notes entitled to the money must look to NTL for payment unless an
abandoned property law designates another person and all liability of the
trustee and the Paying Agent shall cease. Other than as set forth in this
paragraph, the indenture does not provide for any prescription period for the
payment of interest and principal on the notes.
    
 
TRANSFER AND EXCHANGE
 
   
     A holder may transfer or exchange interests in the notes in accordance with
procedures described in "Book-Entry; Delivery and Form." The registrar and the
trustee may require a holder, among other things, to furnish appropriate
endorsements and transfer documents and NTL may require a holder to pay any
taxes and fees required by law or permitted by the indenture. NTL is not
required to transfer or exchange any note selected for redemption. Also, NTL is
not required to transfer or exchange any note for a period of 15 days before a
selection of notes to be redeemed.
    
 
   
     The registered holder of a note will be treated as the owner of it for all
purposes.
    
 
AMENDMENT, SUPPLEMENT AND WAIVER
 
   
     Except as provided in the next succeeding paragraph, any indenture or class
of notes may be amended or supplemented with the consent of the holders of at
least a majority in principal amount of the then outstanding notes to which that
indenture applies, including consents obtained in connection with a tender offer
or exchange offer for those notes, and any existing default or compliance with
any provision of any indenture or close of notes may be waived with the consent
of the holders of a majority in principal amount of the then outstanding notes
to which that indenture applies, including consents obtained in connection with
a tender offer or exchange offer for those notes.
    
 
                                       53
<PAGE>   57
 
   
     Without the consent of each holder affected, an amendment or waiver may
not, with respect to any notes held by a non-consenting holder of notes:
    
 
   
         (1) reduce the amount of notes whose holders must consent to an
             amendment, supplement or waiver,
    
 
   
         (2) reduce the principal of or change the fixed maturity of any note or
             alter the provisions with respect to the redemption of the notes,
             except for repurchases of the notes pursuant to the covenants
             described above under the captions "-- Asset Sales" and "-- Change
             of Control",
    
 
   
         (3) reduce the rate of or change the time for payment of interest on
             any note,
    
 
   
         (4) waive a default in the payment of principal of or interest on any
             notes, 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,
    
 
   
         (5) make any note payable in money other than that stated in the notes,
    
 
   
         (6) make any change in the provisions of the indenture relating to
             waivers of past Defaults or the rights of holders of notes to
             receive payments of principal of or interest on the notes,
    
 
   
         (7) waive a redemption payment with respect to any note, or
    
 
         (8) make any change in the foregoing amendment and waiver provisions.
 
   
     Notwithstanding the foregoing, without the consent of any holder of notes,
NTL and the trustee may amend or supplement any indenture or class of notes to
cure any ambiguity, defect or inconsistency, to provide for uncertificated notes
in addition to or in place of certificated notes, to provide for the assumption
of NTL's obligations to holders of the notes in the case of a merger or
consolidation, to make any change that would provide any additional rights or
benefits to the holders of the notes or that does not adversely affect the legal
rights under the indenture of any such holder, or to comply with requirements of
the Commission in order to maintain the qualification of any indenture under the
Trust Indenture Act.
    
 
   
     Any notice or communication to a holder of notes shall be mailed by
first-class mail to such holder's address as shown in the register kept by the
Registrar. If a notice or communication is mailed in the manner provided in the
preceding sentence within the time period prescribed, it is duly given, whether
or not the addressee receives it. In addition, if and as long as the notes are
listed on the Luxembourg Stock Exchange, all notices regarding the notes shall
be published in English in one leading newspaper with circulation in Luxembourg.
It is expected that publication of notices will normally be made in the
Luxembourger Wort in Luxembourg.
    
 
GOVERNING LAW
 
   
     The notes and the indentures will be governed exclusively by the laws of
the State of New York.

CONCERNING THE TRUSTEE
 
   
     The indentures contain limitations on the rights of the trustee, should it
become a creditor of NTL, to obtain payment of claims in certain cases, or to
realize on certain property received in respect of any such claim as security or
otherwise. The trustee will be permitted to engage in other transactions;
however, if it acquires any conflicting interest it must eliminate such conflict
within 90 days, apply to the commission for permission to continue or resign.
    
 
   
     The holders of a majority in principal amount of any class of then
outstanding notes will have the right to direct the time, method and place of
conducting any proceeding for exercising any remedy available to the trustee
under the applicable indenture, subject to certain exceptions. The indentures
provide that in case an Event of Default shall occur, which shall not be cured,
the trustee will be required, in the exercise of its power, to use the degree of
care of a prudent man in the conduct of his own affairs. Subject to such
provisions, the trustee will be under no obligation to exercise any of its
rights or powers under the indenture at the request of any holder of notes,
unless such holder shall have offered to the trustee security and indemnity
satisfactory to it against any loss, liability or expense.
    
 
   
     The Chase Manhattan Bank is also the trustee for all of the existing notes
and the convertible notes.
    
 
LISTING
 
   
     NTL will apply to list the new notes on the Luxembourg Stock Exchange. The
legal notice relating to the issue of the new notes and the Certificate of
Incorporation and By-laws of NTL will be registered prior to the listing with
the Registrar of the District Court in Luxembourg. Those documents will be
available for inspection from the Registrar of the District Court in Luxembourg.
Copies of those documents can also be obtained upon request from the Registrar
of the District Court in Luxembourg. In addition, if and as long as the notes
are listed on the Luxembourg Stock Exchange, an agent for making payments on,
and transfers of, notes will be maintained in Luxembourg. NTL has initially
designated Chase Manhattan Bank Luxembourg S.A. as its agent for such purposes.

     The following summary of the registration rights provided in the
registration rights agreements and the old notes is not complete. You should
refer to the registration rights agreements and the old notes for a full
description of the registration rights that apply to the old notes.
 
   
     Holders of new notes are not generally entitled to any registration rights
with respect to the new notes. Under the registration rights agreements, holders
of old notes are entitled to some registration rights. Under each of the
registration rights agreements, we agreed to file with the SEC a registration
statement, including a prospectus, on the appropriate form under the Securities
Act with respect to an offer to exchange each class of the old notes for new
notes registered under the Securities Act with terms substantially identical to
those of each class of the old notes. If:
    
 
   
     (1) with respect to any class of the old notes we are not required to file
         the exchange offer registration statement or permitted to consummate
         the exchange offer because the exchange offer is not permitted by
         applicable law or SEC policy or
    
 
     (2) any holder of transfer restricted notes notifies us within the
         specified time period that
 
   
         (A) it is prohibited by law or SEC policy from participating in the
             exchange offer or
    
 
         (B) that it may not resell the exchange securities acquired by it in
             the exchange offer to the public without delivering a prospectus
             and the prospectus contained in the exchange offer registration
             statement is not appropriate or available for such resales or
 
   
         (C) that it is a broker-dealer and owns old notes acquired directly
             from us or an affiliate of NTL,
    
 
   
we will file with the SEC a shelf registration statement to cover resales of the
applicable old notes by the holders who satisfy some conditions relating to the
provision of information in connection with the shelf registration statement. We
will use our best efforts to cause the applicable registration statement to be
declared effective as promptly as possible by the SEC.
    
 
   
     For purposes of the foregoing, transfer restricted notes means each old
note until:
    
 
     (1) the date on which such note has been exchanged by a person other than a
         broker-dealer for a new note in the exchange offer,
 
     (2) following the exchange by a broker-dealer in the exchange offer of an
         old note for a new note, the date on which such new note is sold to a
         purchaser who
 
                                       71
<PAGE>   75
 
         receives from such broker-dealer on or prior to the date of such sale a
         copy of the prospectus contained in the exchange offer registration
         statement,
 
     (3) the date on which such old note has been effectively registered under
         the Securities Act and disposed of in accordance with the shelf
         registration statement,
 
     (4) the date on which such old note is distributed to the public pursuant
         to Rule 144 under the Securities Act or any similar provision then in
         effect or is saleable pursuant to Rule 144(k) under the Securities Act
         or
 
     (5) the date upon which such old note ceases to be outstanding.
 
   
     The registration rights agreements provide that:
    
 
   
     (a) we will file an exchange offer registration statement with the SEC on
         or prior to January 31, 1999 with respect to the 11 1/2% new notes, and
         on or prior to February 4, 1999 with respect to the 12 3/8% new notes,
    
 
   
     (b) we will use our best efforts to have the exchange offer registration
         statement declared effective by the SEC on or prior to May 1, 1999 with
         respect to the 11 1/2% new notes, and on or prior to May 5, 1999 with
         respect to the 12 3/8% new notes,
    
 
   
     (c) unless the exchange offer would not be permitted by applicable law or
         SEC policy, we will commence the exchange offer and use our best
         efforts to issue on or prior to June 10, 1999, 11 1/2% new notes in
         exchange for all 11 1/2% old notes tendered before that date in the
         exchange offer and to issue on or prior to June 14, 1999, 12 3/8% new
         notes in exchange for all 12 3/8% old notes tendered before that date
         in the exchange offer and
    
 
   
     (d) if obligated to file the shelf registration statement, we will use our
         best efforts to file the shelf registration statement with the SEC as
         promptly as practicable after such filing obligation arises and to
         cause the shelf registration to be declared effective by the SEC on or
         prior to June 10, 1999 with respect to the 11 1/2% new notes, and on or
         prior to June 14, 1999 with respect to the 12 3/8% new notes.
    
 
   
If, with respect to any class of the notes:
    
 
     (1) we fail to file the exchange offer registration statement on or before
         the date specified for such filing,
 
     (2) the exchange offer registration statement is not declared effective on
         or prior to May 1, 1999 with respect to the 11 1/2% new notes, and on
         or prior to May 5, 1999 with respect to the 12 3/8% new notes or
 
   
     (3) we fail to consummate the exchange offer, or a shelf registration
         statement is not declared effective, within the specified time frames,
         then we will pay special interest pursuant to provisions of the old
         notes to each holder of the applicable old notes.

12 3/8% old notes, as applicable, with respect to each subsequent applicable
accrual period until all registration defaults have been cured, up to a maximum

determined daily. All accrued special interest will be paid by us on each
interest payment date to the applicable global note holder by wire transfer of
immediately available funds or by federal funds check and to holders of
certificated securities by wire transfer to the accounts specified by them or by
mailing checks to their registered addresses if no such accounts have been
specified. Following the cure of all registration defaults, the accrual of
special interest will cease.
    
 
   
     In the event that a shelf registration statement is declared effective
pursuant to the terms of a registration rights agreement, if we fail 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:
    
 
     (1) the date that the shelf registration statement is again deemed
         effective,
 
     (2) November 2, 2000 with respect to the 11 1/2% old notes or November 6,
         2000 with respect to the 12 3/8% old notes or
 
     (3) the date as of which all of the transfer restricted notes are sold
         pursuant to the shelf registration statement,
 
   
special interest pursuant to provisions of the notes shall accrue at a rate per
annum equal to 0.50% of the principal amount of the 11 1/2% old notes or the
accreted value of the 12 3/8% old notes, as applicable, determined daily, or
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 of each year, to the holders of record on the immediately
preceding March 15 and September 15, respectively. We will be permitted to
suspend use of the prospectus that is part of any shelf registration

statement during specified periods of time and in various circumstances relating
to pending corporate developments and public filings with commission and similar
events.
    
 
     Special interest on the old notes, if any, will be computed on the basis of
a 360-day year comprised of twelve 30-day months.
 
     Holders of old notes will be required to make certain representations to us
as described in the registration rights agreement in order to participate in the
exchange offer and will be required to deliver information to be used in
connection with the shelf registration statement and to provide comments on the
shelf registration statement within the time periods set forth in the
registration rights agreement in order to have their notes included in the shelf
registration statement and benefit from the provisions regarding special
interest pursuant to provisions of the old notes, as set forth above.
 
   
     To comply with the securities laws of some jurisdictions, it may be
necessary to qualify for sale or register the new notes before offering or
selling such new notes. We have agreed, subject to some limitations set forth in
the registration rights agreements, to register or qualify the new notes held by
broker-dealers for offer or sale under the securities or blue sky laws of some
jurisdictions as a holder of new notes reasonably requests in writing. Unless we
are so requested, we do not intend to register or qualify the sale of the new
notes in any jurisdictions.

                       FEDERAL INCOME TAX CONSIDERATIONS
 
     The following is a discussion of the material U.S. federal income tax
consequences of an exchange of old notes for the new notes and the ownership of
the new notes. It deals only with notes held as capital assets by initial
holders of old notes, and does not deal with special situations, such as those
of dealers in securities, financial institutions, insurance companies and
holders whose "functional currency" is not the U.S. dollar, or special rules
with respect to straddle or "hedging" transactions. The discussion below is
based upon the Internal Revenue Code of 1986, as amended and regulations,
rulings and judicial decisions thereunder as of the date hereof, and such
authorities may be repealed, revoked or modified (including retroactively) so as
to result in federal income tax consequences different from those discussed
below.
 
     You are urged to consult your tax advisor regarding the tax consequences
that may be specific to you of the exchange of old notes for new notes and the
ownership of the new notes, as well as any tax consequences arising under any
state, local or foreign laws.
 
     As used herein, the term "U.S. holder" means a beneficial owner of a note
that is for United States federal income tax purposes
 
     (1) a citizen or resident of the United States,
 
     (2) a corporation, partnership or other entity created or organized under
         the laws of the United States or any political subdivision thereof or
         therein,
 
     (3) an estate or trust described in Section 7701(a)(30) of the Internal
         Revenue Code, or
 
     (4) a person whose worldwide income or gain is otherwise subject to U.S.
         federal income taxation on a net income basis.
 
As used herein, the term "Non-U.S. holder" means a holder of a note that is not
a U.S. holder.
 
EXCHANGE OF NOTES
 
     There will be no federal income tax consequences to holders exchanging old
notes for new notes pursuant to the exchange offer since the exchange offer will
be by operation of the original terms of the old notes, pursuant to a unilateral
act by us, and will not result in any material alteration in the terms of the
old notes. Each exchanging holder will have the same adjusted tax basis and
holding period in the new notes as it had in the old notes immediately before
the exchange.
 
TAXATION OF NOTES -- U.S. HOLDERS
 
     Payments of Interest.   Payments of interest on the 11 1/2% notes generally
will be taxable to a U.S. holder as ordinary interest income at the time such
payments are accrued or received (in accordance with the U.S. holder's method of
accounting for federal income tax purposes).
 
                                       75
<PAGE>   79
 
     If NTL meets the Foreign Active Business Requirement discussed below,
interest, including OID as defined below, paid on the notes may be treated as
foreign source income. Due to the factual nature of the issue, however, it is
not certain that NTL will meet such requirement.
 
     Original Issue Discount.   Because the 12 3/8% old notes were issued with
original issue discount ("OID"), the 12 3/8% new notes issued in exchange for
the 12 3/8% old notes will also bear OID that each U.S. holder of a 12 3/8% new
note generally will be required to include in income as it accrues on a
yield-to-maturity basis over the term of the 12 3/8% new note in advance of cash
payments attributable to such income (regardless of whether the holder is a cash
or accrual basis taxpayer). The amount of OID with respect to a 12 3/8% new note
will equal the excess of the stated redemption price at maturity of such 12 3/8%
new note over its issue price. The stated redemption price at maturity will
include all payments required to be made on the 12 3/8% new note, whether
denominated as principal or interest (other than payments subject to remote or
incidental contingencies). The issue price of the 12 3/8% new notes equals the
issue price of the 12 3/8% old notes, which was $55.505 per $1,000 principal
amount at maturity.
 
     A U.S. holder of a debt instrument that bears OID is required to include in
gross income an amount equal to the sum of the daily portions of OID for each
day during the taxable year in which such holder holds the debt instrument. The
daily portions of OID are determined by allocating to each day in an accrual
period the pro rata portion of the OID that is allocable to the accrual period.
The amount of OID that is allocable to an accrual period with respect to 12 3/8%
new notes generally will be equal to the product of the adjusted issue price of
such notes at the beginning of the accrual period (the issue price of the
12 3/8% new notes determined as described above, generally increased by all
prior accruals of OID and decreased by the amount of payments made on such
12 3/8% new notes) and the 12 3/8% new notes' yield-to-maturity (the discount
rate, which, when applied to all payments under the 12 3/8% new notes and
12 3/8% old notes, results in a present value equal to the issue price of such
12 3/8% new notes). In the case of the final accrual period, the allocable OID
generally is the difference between the amount payable at maturity and the
adjusted issue price at the beginning of the accrual period. All payments on a
12 3/8% Note generally will be viewed first as a payment of previously accrued
OID (to the extent thereof), with payments considered made from the earliest
accrual period, and then as a payment of principal.
 
     NTL will furnish annually to the Internal Revenue Service and to U.S.
holders (other than with respect to certain exempt holders, including, in
particular, corporations) information with respect to the OID accruing while the
12 3/8% notes were held by the U.S. Holders.
 
     Under certain circumstances described above, the Company will be required
to pay special interest on the 12 3/8% notes if it fails to comply with certain
of its obligations under the registration rights agreement. Although not free
from doubt, such additional amount should be taxable to a U.S. holder as
ordinary income at the time it accrues or is received in accordance with such
holder's regular method of accounting. It is possible,
 
                                       76
<PAGE>   80
 
however, that the IRS may take a different position, in which case the timing
and the amount of income on the 12 3/8% notes may be different.
 
     Disposition of Notes.   A U.S. holder will generally recognize gain or loss
upon the sale, exchange, retirement or other disposition of new notes equal to
the difference between the amount realized on the disposition (other than
amounts attributable to accrued but unpaid interest) and the U.S. holder's
adjusted tax basis in the new notes. A U.S. holder's adjusted tax basis in a new
note will generally be the cost of the old note, (and, in the case of 12 3/8%
new notes) increased by any OID previously included in income by such holder and
decreased by any amount received on the note that is not treated as ordinary
interest income. Such gain or loss generally would be capital gain or loss. In
the case of a U.S. holder who is an individual, such capital gain will be
subject to tax at a maximum 20% rate if the holding period for the new note
(which includes the holding period of the old note) is more than one year.
 
TAXATION OF NOTES -- NON-U.S. HOLDERS
 
     The following discussion is limited to the U.S. federal income tax
consequences relevant to a holder of a new note that is a Non-U.S. holder.
 
     Subject to the discussion of backup withholding below, payments of interest
(including OID) on a new note to any Non-U.S. holder will generally not be
subject to U.S. federal income or withholding tax, provided that:
 
     (1) the holder is not
 
         (a) a direct or indirect owner of 10% or more of the total voting power
             of all voting stock of NTL,
 
         (b) a controlled foreign corporation related to NTL through stock
             ownership or
 
         (c) a foreign tax-exempt organization or a foreign private foundation
             for U.S. federal income tax purposes,
 
     (2) such interest payments are not effectively connected with the conduct
         by the Non-U.S. holder of a trade or business within the United States
         and
 
     (3) NTL or its paying agent receives
 
         (a) from the Non-U.S. holder, a properly completed Form W-8 (or
             substitute Form W-8) under penalties of perjury which provides the
             Non-U.S. holder's name and address and certifies that the Non-U.S.
             holder of the note is a Non-U.S. holder or
 
         (b) from a security clearing organization, bank or other financial
             institution that holds the notes in the ordinary course of its
             trade or business (a "financial institution") on behalf of the
             Non-U.S. holder, certification under penalties of perjury that such
             a Form W-8 (or substitute Form W-8) has been received by it, or by
             another such financial institution, from the Non-U.S. holder, and a
             copy of the Form W-8 (or substitute Form W-8) is furnished to the
             payor.
 
                                       77
<PAGE>   81
 
     A Non-U.S. holder that does not qualify for exemption from withholding
under the preceding paragraph generally will be subject to withholding of U.S.
federal income tax at the rate of 30% (or lower applicable treaty rate) on
payments of interest (including OID) on the new notes unless the foreign active
business requirement is met, as described below.
 
     If the payments of interest (including OID) on a new note are effectively
connected with the conduct by a Non-U.S. holder of a trade or business in the
United States, such payments will be subject to U.S. federal income tax on a net
basis at the rates applicable to United States persons generally (and, with
respect to corporate holders, may also be subject to a 30% branch profits tax).
If payments are subject to U.S. federal income tax on a net basis in accordance
with the rules described in the preceding sentence, such payments will not be
subject to United States withholding tax so long as the holder provides NTL or
its paying agent with a properly executed Form 4224.
 
     In addition, if NTL can show to the satisfaction of the IRS that at least
80% of the gross income from all sources for the 3-year period ending with the
close of NTL's taxable year preceding the interest payment (or such period as
may be applicable) is "active foreign business income" (the "foreign active
business requirement"), then such interest would be treated as foreign source
income that is not subject to U.S. withholding. Active foreign business income
is generally gross income of a corporation derived from sources outside the
U.S., or is attributable to income so derived by a subsidiary of the
corporation, which is attributable to the active conduct of a trade or business
in the foreign jurisdiction by the corporation (or subsidiary). It is uncertain
whether NTL would meet this test for treating interest income as non-U.S.
source.
 
     Non-U.S. holders should consult any applicable income tax treaties, which
may provide for a lower rate of withholding tax exemption from or reduction of
branch profits tax, or other rules different from those described above.
 
     Sale, Exchange or Redemption of Notes.   Subject to the discussion
concerning backup withholding, any gain realized by a Non-U.S. holder on the
sale, exchange, retirement or other disposition of a new note generally will not
be subject to a U.S. federal income tax, unless
 
     (1) such gain is effectively connected with the conduct by such Non-U.S.
         holder of a trade or business within the United States,
 
     (2) the Non-U.S. holder is an individual who is present in the United
         States for 183 days or more in the taxable year of the disposition and
         certain other conditions are satisfied, or
 
     (3) the Non-U.S. holder is subject to tax pursuant to the provisions of
         U.S. tax law applicable to certain U.S. expatriates.
 
                                       78
<PAGE>   82
 
     Federal Estate Tax.   New notes held (or treated as held) by an individual
who is a Non-U.S. holder at the time of his or her death will not be subject to
U.S. federal estate tax provided that
 
     (1) the individual does not actually or constructively own 10% or more of
         the total voting power of all voting stock of NTL and
 
     (2) income on the notes was not effectively connected with the conduct by
         such Non-U.S. holder of a trade or business within the United States.
 
INFORMATION REPORTING AND BACKUP WITHHOLDING
 
     Payments, including OID, with respect to the new notes and the proceeds
upon the sale or other disposition of the new notes may be subject to the
information reporting and possible U.S. backup withholding at a 31% rate. Backup
withholding will not apply to U.S. holders who furnish a correct taxpayer
identification number and provide other certification or who are otherwise
exempt from backup withholding. Copies of those information returns may also be
made available, under the provisions of a specific treaty or agreement, to the
tax authorities of the country in which the Non-U.S. holder resides.
 
     The regulations provide that backup withholding, which generally is a
withholding tax imposed at the rate of 31% on payments to persons that fail to
furnish certain required information, and information reporting will not apply
to payments made in respect to the new notes by NTL to a Non-U.S. holder, if the
holder certifies as to its non-U.S. status under penalties of perjury or
otherwise establishes an exemption, provided that neither the Company nor its
paying agent has actual knowledge that the holder is a U.S. person or that the
condition of any other exemption are not, if fact, satisfied.
 
     The payment of the proceeds from the disposition of new notes to or through
the United States office of any broker, U.S. or foreign, will be subject to
information reporting and possible backup withholding unless the owner certifies
as to its non-U.S. status under penalty of perjury or otherwise establishes an
exemption, provided that the broker does not have actual knowledge that the
holder is a U.S. person or that the conditions of any other exemption are not,
if fact, satisfied. The payment of the proceeds from the disposition of a new
note to or through a non-U.S. office of a non-U.S. broker that is not a U.S.
related person will not be subject to information reporting or backup
withholding. For this purpose, a "U.S. related person" is
 
         (1)  a "controlled foreign corporation" for U.S. federal income tax
              purposes or
 
         (2) a foreign person 50% or more of whose gross income from all sources
             for the three-year period ending with the close of its taxable year
             preceding the payment (or for such part of the period that the
             broker has been in existence) is derived from activities that are
             effectively connected with the conduct of a U.S. trade or business.
 
     In the case of the payment of proceeds from the disposition of new notes to
or through a non-U.S. office of a broker that is a U.S. related person, the
regulations
 
                                       79
<PAGE>   83
 
require information reporting on the payment unless the broker has documentary
evidence in its files that the owner is a Non-U.S. holder and the broker has no
knowledge to the contrary. Backup withholding will not apply to payments made
through foreign offices of a broker that is a U.S. person or a U.S. related
person, absent actual knowledge that the payee is a U.S. person.
 
     Any amounts withheld under the backup withholding rules from a payment to a
Non-U.S. holder will be allowed as a refund or a credit against such Non-U.S.
holder's federal income tax liability, provided that the requisite procedures
are followed.
 
     The Treasury Department recently promulgated final regulations regarding
the withholding and information reporting rules discussed above. In general, the
final regulations do not significantly alter the substantive withholding and
information reporting requirements but rather unify current certification
procedures and forms and clarify reliance standards. The final regulations are
generally effective for payments made after December 31, 1999, subject to
certain transition rules. Non-U.S. holders should consult their own tax advisors
with respect to the impact, if any, of the final regulations.

                              PLAN OF DISTRIBUTION
 
   
     If you are a broker-dealer and hold old notes for your own account as a
result of market-making activities or other trading activities and you receive
new notes in exchange for old notes in the exchange offer, you may be a
statutory underwriter and must acknowledge that you will deliver a prospectus in
connection with any resale of such new notes. This prospectus, as it may be
amended or supplemented from time to time, may be used by a broker-dealer in
connection with resales of new notes received in exchange for old notes where
such old notes were acquired as a result of market-making activities or other
trading activities. We acknowledge and, unless you are a broker-dealer, you must
acknowledge that you are not engaged in, do not intend to engage in, and have no
arrangement or understanding with any person to participate in a distribution of
new notes. We have agreed that starting on the expiration date of the exchange
offer and ending on the close of business on the 180th day following the
expiration date of the exchange offer, we will make this prospectus, as amended
or supplemented, available to any broker-dealer for use in connection with any
such resale.
    
 
   
     We will not receive any proceeds from any sale of new notes by
broker-dealers. New notes received by broker-dealers for their own account
pursuant to the exchange offer may be sold from time to time in one or more
transactions in the over-the-counter market, in negotiated transactions, through
the writing of options on the new notes or a combination of those methods of
resale, at market prices prevailing at the time of resale, at prices related to
such prevailing market prices or negotiated prices. Any resale of that kind may
be made directly to purchasers or to or through brokers or dealers who may
receive compensation in the form of commissions or concessions from any such
broker-dealer and/or the purchasers of any such new notes. Any broker-dealer
that resells new notes that were received by it for its own account pursuant to
the exchange offer and any broker or dealer that participates in a distribution
of such new notes may be deemed to be an "underwriter" within the meaning of the
Securities Act and any profit on any such resale of new notes and any
commissions or concessions received by any such persons may be deemed to be
underwriting compensation under the Securities Act. The letter of transmittal
states that by acknowledging that it will deliver and by delivering a
prospectus, a broker-dealer will not be deemed to admit that it is an
"underwriter" within the meaning of the Securities Act.
    
 
     For a period of 180 days after the expiration date, we will promptly send
additional copies of this prospectus and any amendment or supplement to this
prospectus to any broker-dealer that requests such documents in the letter of
transmittal.
 
     We have agreed to pay all expenses incident to the exchange offer
(including the expenses of one counsel for the holders of the notes) other than
commissions or concessions of any brokers or dealers and will indemnify the
holders of the notes, including any broker-dealers, against various liabilities,
including liabilities under the Securities Act.

                         BOOK-ENTRY; DELIVERY AND FORM
 
THE EXCHANGE
 
     New notes exchanged for old notes through DTC may be represented by one or
more global notes. The global new notes will be deposited on the date of the
closing of the exchange offer with the trustee as custodian of DTC and pursuant
to a FAST Balance Certificate Agreement between the trustee or the registrar, as
the case may be, and DTC and registered in the name of Cede & Co., as nominee of
DTC. Such nominee is referred to as the "global security holder".
 
     New notes exchanged for old notes which are in the form of registered
definitive certificates will be issued in the form of certificated notes. Such
certificated notes may, unless the global new notes have previously been
exchanged for certificated notes, be exchanged for an interest in the global new
notes representing the principal amount at maturity of new notes being
transferred.
 
DEPOSITORY PROCEDURES
 
     DTC has advised us that DTC is a limited-purpose trust company created to
hold notes for its participating organizations (collectively, the
"participants") and to facilitate the clearance and settlement of transactions
in those securities between the participants through electronic book-entry
changes in accounts of the participants. The participants include securities
brokers and dealers (including the initial purchasers), banks, trust companies,
clearing corporations and certain other organizations. Access to DTC's system is
also available to other entities such as banks, brokers, dealers and trust
companies that clear through or maintain a custodial relationship with a
participant, either directly or indirectly (collectively, the "indirect
participants"). Persons who are not participants may beneficially own notes held
by or on behalf of DTC only through the participants or the indirect
participants. The ownership interest and transfer of ownership interest of each
actual purchaser of each note held by or on behalf of DTC are recorded on the
records of the participants and the indirect participants.
 
   
     Euroclear and CEDEL hold securities for participating organizations and
facilitate the clearance and settlement of securities transactions between their
respective participants through electronic book-entry changes in accounts of
such participants. Euroclear and CEDEL provide to their participants, among
other things, services for safekeeping, administration, clearance and settlement
of internationally traded securities and securities lending and borrowing.
Euroclear and CEDEL interface with domestic securities markets. Euroclear and
CEDEL Participants and financial institutions such as initial purchasers,
securities brokers and dealers, banks, trust companies and certain other
organizations. Indirect access to Euroclear or CEDEL is also available to others
such as banks, brokers, dealers and trust companies that clear through or
maintain a custodian relationship with a Euroclear or CEDEL participant, either
directly or indirectly.
    
 
     DTC has also advised us that pursuant to procedures established by it,
 
         (1) upon deposit of the global new notes, DTC will credit the accounts
             of participants with portions of the principal amount of the global
             new notes representing the new notes and
 
                                       82
<PAGE>   86
 
         (2) ownership of such interests in the global new notes will be shown
             on, and the transfer of ownership thereof will be effected only
             through, records maintained by DTC with respect to the
             participants, or by the participants and the indirect participants
             with respect to other owners of beneficial interests in the global
             new notes.
 
     Investors in a global new note may hold their interests therein directly
through DTC, if they are participants in such system, or indirectly through
organizations including Euroclear and CEDEL which are participants in such
system. Euroclear and CEDEL will hold interests in a global new note on behalf
of their participants through their respective depositories, which in turn will
hold such interests in the global new note customers' securities accounts in
their respective names on the books of DTC. The Morgan Guaranty Trust Company,
Brussels office, will initially act as depository for Euroclear, and Citibank,
N.A., will initially act as depository for CEDEL. All interests in a global new
note, including those held through Euroclear or CEDEL, may be subject to the
procedures and requirements of DTC. Those interests held through Euroclear or
CEDEL may also be subject to the procedures and requirements of such system.
 
   
     The laws of some states require that certain persons take physical delivery
in definitive form of securities that they own. Consequently, the ability to
transfer beneficial interests in a global new note to such persons may be
limited to that extent. Because DTC can act only on behalf of the participants,
which in turn act on behalf of the indirect participants and certain banks, the
ability of a person having beneficial interests in a global new note to pledge
such interests to persons or entities that do not participate in the DTC system,
or otherwise take actions in respect of such interests, may be affected by the
lack of a physical certificate evidencing such interests.
    
 
     Except as described below, owners of interests in the global new notes will
not have new notes registered in their names, will not receive physical delivery
of new notes in certificated form and will not be considered the registered
owners or holders of new notes under the indentures for any purpose.
 
     Payments in respect of the principal of and premium, if any and interest on
a global new note will be made through one or more paying agents appointed under
the indentures (which will initially include the trustee) and will be payable to
DTC or its nominee in its capacity as the registered holder under the applicable
indenture. Under the terms of the indentures, NTL and the trustee will treat the
persons in whose names the new notes, including the global new notes
representing the new notes, are registered as the owners thereof for the purpose
of receiving such payments and for any and all other purposes whatsoever.
Consequently, none of NTL, the trustee, any transfer agent or any agent of NTL,
the trustee or any transfer agent has or will have any responsibility or
liability for
 
     (1) any aspect or accuracy of DTC's records or any participant's or
         indirect participant's records relating to or payments made on account
         of beneficial ownership interests in the global notes, or for
         maintaining, supervising or reviewing any of DTC's records or any
         participant's or indirect participant's records relating to the
         beneficial ownership interests in the global new notes, or
 
                                       83
<PAGE>   87
 
     (2) any other matter relating to the actions and practices of DTC or any of
         the participants or the indirect participants.
 
     DTC has advised us that its current practice, upon receipt of any payment
in respect of notes such as the new notes (including principal and interest), is
to credit the accounts of the relevant participants with the payment on the
payment date, in amounts proportionate to their respective holdings in principal
amount of beneficial interests in the relevant security as shown on the records
of DTC. Payments by the participants and the indirect participants to the
beneficial owners of new notes will be governed by standing instructions and
customary practices and will not be the responsibility of any of DTC, the
trustee, the registrar, the transfer agent or NTL. None of NTL, the registrar,
the transfer agent or the trustee will be liable for any delay by DTC or any of
the participants in identifying the beneficial owners of the notes, and NTL, the
registrar, the transfer agent and the trustee may conclusively rely on and will
be protected in relying on instructions from DTC or its nominee as the
registered owner of the global notes for all purposes.
 
     Except for trades involving only Euroclear and CEDEL participants,
interests in the global notes will trade in DTC's same-day funds settlement
system and secondary market trading activity in such interests will therefore
settle in immediately available funds, subject in all cases to the rules and
procedures of DTC and the participants.
 
     Transfers between participants in DTC will be effected in accordance with
DTC's procedures and will be settled in same-day funds. Transfers between
accountholders in Euroclear and CEDEL will be effected in the ordinary way in
accordance with their respective rules and operating procedures.
 
     Cross-market transfers between the account holders in DTC, on the one hand,
and account holders in Euroclear or CEDEL, on the other hand, will be effected
through DTC in accordance with DTC's rules on behalf of Euroclear or CEDEL, as
the case may be, by its respective depository; however, such cross-market
transactions will require delivery of instructions to Euroclear or CEDEL, as the
case may be, by the counterparty in such system in accordance with the rules and
procedures and within the established deadlines (Brussels time) of such system.
Euroclear or CEDEL, as the case may be, will, if the transaction meets its
settlement requirements, deliver instructions to its respective depository to
take action to effect final settlement on its behalf by delivering or receiving
interests in the relevant global note in DTC, and making or receiving payment in
accordance with normal procedures for same-day funds settlement applicable to
DTC. Euroclear and CEDEL account holders may not deliver instructions directly
to the depositories for Euroclear or CEDEL.
 
   
     Because of time zone differences, the securities account of a Euroclear or
CEDEL account holder purchasing an interest in a global note from an account
holder in DTC will be credited, and any such crediting will be reported to the
relevant Euroclear or CEDEL participant, during the securities settlement
processing day (which must be a business day for Euroclear or CEDEL) immediately
following the settlement date of DTC. Cash received in Euroclear or CEDEL as a
result of sales of interests in a global new note by or through a Euroclear or
CEDEL account holder to a participant in DTC
    
 
                                       84
<PAGE>   88
 
will be received with value on the settlement date of DTC but will be available
in the relevant Euroclear or CEDEL cash account only as of the business day for
Euroclear or CEDEL following DTC's settlement date.
 
     DTC has advised us that it will take any action permitted to be taken by a
holder of new notes only at the direction of one or more participants to whose
account with DTC interests in the global notes are credited and only in respect
of such portion of the aggregate principal amount of the notes as to which such
participant or participants has or have given such direction. However, if any of
the events described under "-- Exchange of book entry notes for certificated
notes" occurs, DTC reserves the right to exchange the global new notes for notes
in certificated form and to distribute such new notes to its participants.
 
     The information in this section concerning DTC, Euroclear and CEDEL and
their book-entry systems has been obtained from sources that we believe to be
reliable, but we take no responsibility for the accuracy thereof.
 
     Although DTC, Euroclear and CEDEL have agreed to the foregoing procedures
to facilitate transfers of interests in the global new notes among account
holders in DTC and account holders of Euroclear and CEDEL, they are under no
obligation to perform or to continue to perform such procedures, and such
procedures may be discontinued at any time. None of NTL, the registrar, the
transfer agent or the trustee nor any agent of NTL, the registrar, the transfer
agent or the trustee will have any responsibility for the performance by DTC,
Euroclear or CEDEL or their respective participants, indirect participants or
account holders of their respective obligations under the rules and procedures
governing their operations.
 
   Exchange of book-entry notes for certificated notes
 
     A global new note is exchangeable for definitive new notes in registered
certificated form if
 
     (1) DTC
 
         (x) notifies us that it is unwilling or unable to continue as
             depository for the global new note and we then fail to appoint a
             successor depository within 90 days or
 
         (y) has ceased to be a clearing agency registered under the Exchange
             Act,
 
     (2) we, at our option, notify the trustee in writing that we elect to cause
         the issuance of the new notes in certificated form or
 
     (3) there shall have occurred and be continuing a Default or an Event of
         Default with respect to the new notes.
 
In all cases, certificated notes delivered in exchange for any global note or
beneficial interests therein will be registered in the names, and issued in any
approved denominations, requested by or on behalf of the depository (in
accordance with its customary procedures).
 
     If certificated new notes are issued and a holder of a certificated new
note claims that the note has been lost, destroyed or wrongfully taken or if
such new note is
 
                                       85
<PAGE>   89
 
mutilated and is surrendered to the trustee (or, as long as the new notes are
listed on the Luxembourg Stock Exchange, at the specified office of the transfer
agent in Luxembourg), we shall issue and the trustee shall authenticate a
replacement new note if the trustee's and our requirements are met. If required
by the trustee or us, an indemnity bond must be sufficient in the judgment of
both to protect NTL, the trustee, any agent or any authenticating agent from any
loss which any of them may suffer if a new note is replaced. We may charge for
our expenses in replacing a new note.
 
     In case any such mutilated, destroyed, lost or stolen new note has become
or is about to become due and payable, or is about to be purchased by us
pursuant to the provisions of the indenture, NTL in its discretion may, instead
of issuing a new new note, pay or purchase such new note, as the case may be.
 
                                 LEGAL MATTERS
 
     The validity of the issuance of the New Notes will be passed upon for the
Company by Skadden, Arps, Slate, Meagher & Flom LLP, New York, New York, special
counsel for the Company.

                      ENFORCEABILITY OF CIVIL LIABILITIES
 
     A substantial majority of our assets are located outside the United States.
As a result, it may not be possible for you to realize in the United States upon
judgments of courts of the United States predicated upon the civil liability
under the federal securities laws of the United States. The United States and
England do not currently have a treaty providing for the reciprocal recognition
and enforcement of judgments, other than arbitration awards, in civil and
commercial matters. Therefore, a final judgment for the payment of a fixed debt
or sum of money rendered by any United States court based on civil liability,
whether or not predicated solely upon the United States federal securities laws,
would not automatically be enforceable in England. In order to enforce in
England a United States judgment, proceedings must be initiated by way of common
law action before a court of competent jurisdiction in England. An English court
will, subject to what is said below, normally order summary judgment on the
basis that there is no defense to the claim for payment and will not
reinvestigate the merits of the original dispute. In such an action, an English
court will treat the United States judgment as creating a valid debt upon which
the judgment creditor could bring an action for payment, as long as
 
     (1) the United States court had jurisdiction over the original proceeding,
 
     (2) the judgment is final and conclusive on the merits,
 
     (3) the judgment does not contravene English public policy,
 
     (4) the judgment must not be for a tax, penalty or a judgment arrived at by
         doubling, trebling or otherwise multiplying a sum assessed as
         compensation for the loss or damage sustained and
 
     (5) the judgment has not been obtained by fraud or in breach of the
         principles of natural justice.
 
Based on the foregoing, there can be no assurance that you will be able to
enforce in England judgments in civil and commercial matters obtained in any
United States court. There is doubt as to whether an English court would impose
civil liability in an original action predicated solely upon the United States
federal securities laws brought in a court of competent jurisdiction in England.

                     INFORMATION NOT REQUIRED IN PROSPECTUS
 
ITEM 20.   INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     As permitted by Section 102 of the Delaware General Corporation Law (the
"DGCL"), the Company's Amended and Restated Certificate of Incorporation
eliminates a director's personal liability for monetary damages to the Company
and its stockholders arising from a breach or alleged breach of a director's
fiduciary duty except for liability under Section 174 of the DGCL or liability
for a breach of the director's duty of loyalty to the Company or its
stockholders, for acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of law or for any transaction in
which the director derived an improper personal benefit. The effect of this
provision in the certificate of incorporation is to eliminate the rights of the
Company and its stockholders (through stockholders, derivative suits on behalf
of the Company) to recover monetary damages against a director for breach of
fiduciary duty as a director (including breaches resulting from negligent or
grossly negligent behavior) except in the situations described above.
 
     The Company's Restated By-laws provide that directors and officers of the
Company shall be indemnified against liabilities arising from their service as
directors and officers to the full extent permitted by law. Section 145 of the
DGCL empowers a corporation to indemnify any person who was or is a party or is
threatened to be made a party to any threatened, pending or completed action,
suit or proceeding, whether civil, criminal, administrative or investigative
(other than an action by or in the right of the corporation) by reason of the
fact that he is or was a director, officer, employee or agent of the corporation
or is or was serving at the request of the corporation as a director, officer,
employee or agent of another corporation, partnership, joint venture, trust or
other enterprise, against expenses (including attorney's fees), judgments, fines
and amounts paid in settlement actually and reasonably incurred by him in
connection with such action, suit or proceeding if he acted in good faith and in
a manner he reasonably believed to be in, or not opposed to, the best interests
of the corporation, and, with respect to any criminal action or proceeding, had
no reasonable cause to believe his conduct was unlawful.
 
     Section 145 also empowers a corporation to indemnify any person who was or
is a party or is threatened to be made a party to any threatened, pending or
completed action or suit by or in the fight of the corporation to procure a
judgment in its favor by reason of the fact that such person acted in any of the
capacities set forth above, against expenses (including attorney's fees)
actually and reasonably incurred by him in connection with the defense or
settlement of such action or suit if he acted under similar standards, except
that no indemnification may be made in respect of any claim, issue or matter as
to which such person shall have been adjudged to be liable to the corporation
unless, and only to the extent that, the Court of Chancery or the court in which
such action was brought shall determine that despite the adjudication of
liability such person
 
                                      II-1
<PAGE>   96
 
is fairly and reasonably entitled to indemnify for such expenses which the court
shall deem proper.
 
     Section 145 further provides that to the extent that a director or officer
of a corporation has been successful in the defense of any action, suit or
proceeding referred to above or in the defense of any claim, issue or matter
therein, he shall be indemnified against expenses (including attorneys' fees)
actually and reasonably incurred by him in connection therewith; that
indemnification provided for by Section 145 shall not be deemed exclusive of any
other rights to which the indemnified party may be entitled; and that the
corporation is empowered to purchase and maintain insurance on behalf of a
director or officer of the corporation against any liability asserted against
him and incurred by him in any such capacity, or arising out of his status as
such, whether or not the corporation would have the power to indemnify him
against such liabilities under Section 145.
 
     The Company has entered into a director and officer indemnity agreement
("Indemnity Agreement") with each officer and director of the Company (an
"Indemnitee"). Under the bylaws and these Indemnity Agreements, the Company must
indemnify an Indemnitee to the fullest extent permitted by the DGCL for losses
and expenses incurred in connection with actions in which the indemnitee is
involved by reason of having been a director or officer of the Company. The
Company is also obligated to advance expenses an indemnitee may incur in
connection with such actions before any resolution of the action.

     ITEM 22.   UNDERTAKINGS
 
     The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
Registrant's annual report pursuant to section 13(a) or section 15(d) of the
Securities Exchange Act (and, where applicable, each filing of an employee
benefit plan's annual report pursuant to section 15(d) of the Securities
Exchange Act) that is incorporated by reference in the Registration Statement
shall be deemed to be a new registration statement relating to the securities
offered therein, and the offering of such securities at that time shall be
deemed to be the initial bona fide offering thereof.
 
     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Commission such indemnification is
against public policy as expressed in the Securities Act and is, therefore,
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by the Registrant of expenses incurred or
paid by a director, officer or controlling person of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.
 
     The undersigned registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Item 4, 10(b), 11, or 13 of this form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of the registration statement through the
date of responding to the request.
 
The undersigned registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the registration statement when it became effective.
 
     The undersigned registrant hereby undertakes to file an application for the
purpose of determining the eligibility of the trustee to act under subsection
(a) of Section 310 of the Trust Indenture Act in accordance with the rules and
regulations prescribed by the Commission under Section 305(b)(2) of the Trust
Indenture Act.
